Descriptions,
Performance
and Fees
            The Funds provide a broad range of investment choices. The
            following Fund Summaries identify each Fund's investment
            objective, principal investments and strategies, principal risks,
            performance information and fees and expenses. A more detailed
            "Summary of 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. The
            fact that a Fund had good performance in the past (for example,
            during the year ended 1999) is no assurance that the value of the
            Fund's investments will not decline in the future or appreciate at
            a slower rate. An investment in a Fund is not a deposit of a bank
            and is not insured or guaranteed by the Federal Deposit Insurance
            Corporation or any other government agency.

              objective
</TABLE>


            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in income-producing (e.g.,
            dividend-paying) common stocks of companies with market
            capitalizations of more than $2 billion at the time of investment.
            The Fund may also invest to a limited degree in convertible
            securities and preferred stocks.

             The Fund's initial selection universe consists of the 1,000
            largest publicly traded companies (in terms of market
            capitalization) in the U.S. The portfolio managers classify the
            universe by industry. They then identify the most undervalued
            stocks in each industry based mainly on relative P/E ratios,
            calculated both with respect to trailing operating earnings and
            forward earnings estimates. From this group of stocks, the Fund
            buys approximately 25 stocks with the highest dividend yields. The
            portfolio managers then screen the most undervalued companies in
            each industry by dividend yield to identify the highest yielding
            stocks in each industry. From this group, the Fund buys
            approximately 25 additional stocks with the lowest P/E ratios.

             In selecting stocks, the portfolio managers consider quantitative
            factors such as price momentum (based on changes in stock price
            relative to changes in overall market prices), earnings momentum
            (based on analysts' earnings per share estimates and revisions to
            those estimates), relative dividend yields, valuation relative to
            the overall market and trading liquidity. The portfolio managers
            may replace a stock when a stock within the same industry group
            has a considerably higher dividend yield or lower valuation than
            the Fund's current holding.

             The Fund may invest up to 15% of its assets in foreign
            securities, except that it may invest without limit in American
            Depository Receipts (ADRs). In response to unfavorable market and
            other conditions, the Fund may make temporary investments of some
            or all of its assets in high-quality fixed income securities. This
            would be inconsistent with the Fund's investment objective and
            principal strategies.

Principal
Risks

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

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

Performance
Information The top of the next page shows summary performance 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 and the information to its
            right show performance of the Fund's Institutional Class shares.
            For periods prior to the inception of Administrative Class shares
            (11/30/94), performance information shown in the Average Annual
            Total Returns table for that class is based on the performance of
            the Fund's Institutional Class shares. The prior Institutional
            Class performance has been adjusted to reflect the actual
            distribution and/or service (12b-1) fees and other expenses paid
            by Administrative Class shares. Prior to May 8, 2000, the Fund had
            a different sub-adviser and would not necessarily have achieved
            the performance results shown on the next page under its current
            investment management arrangements. Past performance is no
            guarantee of future results.

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of companies
            with market capitalizations of more than $5 billion at the time of
            investment and below-average valuations whose business
            fundamentals are expected to improve. To achieve income, the Fund
            invests a portion of its assets in income-producing (e.g.,
            dividend-paying) common stocks.

             The portfolio manager selects stocks for the Fund using a "value"
            style. The portfolio manager invests primarily in stocks of
            companies having below-average valuations whose business
            fundamentals are expected to improve. The portfolio manager
            determines valuation based on characteristics such as price-to-
            earnings, price-to-book, and price-to-cash flow ratios. The
            portfolio manager analyzes stocks and seeks to identify the key
            drivers of financial results and catalysts for change, such as new
            management and new or improved products, that indicate a company
            may demonstrate improving fundamentals in the future. The
            portfolio manager looks to sell a stock when he believes that the
            company's business fundamentals are weakening or when the stock's
            valuation has become excessive.

             The Fund may also invest to a limited degree in other kinds of
            equity securities, including preferred stocks and convertible
            securities. The Fund may invest up to 15% of its assets in foreign
            securities, except that it may invest without limit in American
            Depository Receipts (ADR's). In response to unfavorable market and
            other conditions, the Fund may make temporary investments of some
            or all of its assets in high-quality fixed income securities. This
            would be inconsistent with the Fund's investment objective and
            principal strategies.

--------------------------------------------------------------------------------
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          . Foreign Investment Risk
                                                          . Credit 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 and the information to its
            right show performance of the Fund's Institutional Class shares.
            For periods prior to the inception of Administrative Class shares
            (8/21/97), performance information shown in the Average Annual
            Total Returns table for that class is based on the performance of
            the Fund's Institutional Class shares. The prior Institutional
            Class performance has been adjusted to reflect the actual
            distribution and/or service (12b-1) fees and other expenses paid
            by Administrative Class shares. Prior to May 8, 2000, the Fund had
            a different sub-adviser and would not necessarily have achieved
            the performance results shown on the next page under its current
            investment management arrangements. Past performance is no
            guarantee of future results.

            (1)  The Russell 1000 Value Index is an unmanaged index that
                 measures the performance of companies in the Russell 1000
                 Index considered to have less than average growth
                 orientation. It is not possible to invest directly in the
                 index. The Russell 1000 Value Index replaced the S&P 500
                 Index (an unmanaged index of large capitalization common
                 stocks) as the Fund's comparative index because PIMCO
                 Advisors believes that the Russell 1000 Value Index is more
                 representative of the Fund's investment strategies. For
                 periods ended December 31, 1999, the 1 Year, 5 Year and Fund
                 Inception average total returns of the S&P 500 Index were
                 21.04%, 28.56% and 19.70%, respectively.
            (2)  The Lipper Multi-Cap Value Funds Average is a total return
                 performance average of funds tracked by Lipper Analytical
                 Services, Inc. that invest in companies with a variety of
                 capitalization ranges, without concentrating in any one market
                 capitalization range over an extended period of time. It does
                 not take into account sales charges.

            The portfolio manager analyzes stocks and seeks to identify 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 and the information to its
            right show performance of the Fund's Institutional Class shares.
            For periods prior to the inception of Institutional Class shares
            (12/30/97) and Administrative Class shares (8/31/98), performance
            information shown in the bar chart (including the information to
            its right) and in the Average Annual Total Returns table for those
            classes is based on the performance of the Fund's Class C shares,
            which are offered in a different prospectus. The prior Class C
            performance has been adjusted to reflect the actual fees and
            expenses paid by Institutional Class and Administrative Class
            shares, including no sales charges (loads) and lower distribution
            and/or service (12b-1) fees (if any) and administrative fees.
            Prior to May 7, 1999, the Fund had a different sub-adviser and
            would not necessarily have achieved the performance results shown
            on the next page under its current investment management
            arrangements. Past performance is no guarantee of future results.

            (1) The Russell Mid-Cap Value Index is an unmanaged index that
                measures the performance of medium capitalization companies
                in the Russell 1000 Index with lower price-to-book ratios
                and lower forecasted growth values. It is not possible to
                invest directly in the index. The Mid-Cap Value Index
                replaced the Russell 1000 Value Index (an unmanaged index
                that measures the performance of companies in the Russell
                1000 Index considered to have less than average growth
                orientation) and replaced the S&P 500 Index (an unmanaged
                index of large capitalization common stocks) as one of the
                Fund's comparative indexes because PIMCO Advisors believes
                the Russell Mid-Cap Value Index is more representative of
                the Fund's investment strategies. For periods ended December
                31, 1999, the 1 Year, 5 Years, 10 Years and Fund Inception
                average annual total returns of the Russell 1000 Value Index
                were 7.34%, 23.08%, 15.60% and 15.38%, respectively, and of
                the S&P 500 Index were 21.04%, 28.56%, 18.21% and 19.06%,
                respectively.
            (2) The Lipper Multi-Cap Value Funds Average is a total return
                performance average of funds tracked by Lipper Analytical
                Services, Inc. that invest in companies with a variety of
                capitalization ranges without concentrating in any one market
                capitalization range over an extended period of time. It does
                not take into account sales charges.

            cost of investing in Institutional Class or Administrative Class
            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 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.

</TABLE>

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of companies
            with market capitalizations of at least $1 billion at the time of
            investment. The Fund may invest up to 75% of its assets in
            securities selected for their growth potential. The Fund will
            normally invest at least 25% of its assets in securities selected
            for their income potential, including dividend-paying common
            stocks, preferred stocks, corporate bonds, convertible securities
            and real estate investment trusts (REITs).

             When selecting securities for the Fund's "growth" segment, the
            portfolio managers seek to identify companies with well-defined
            "wealth creating" characteristics, including superior earnings
            growth (relative to companies in the same industry or the market
            as a whole), high profitability and consistent, predictable
            earnings. In addition, through fundamental research, the portfolio
            managers seek to identify companies that are gaining market share,
            have superior management and possess a sustainable competitive
            advantage, such as superior or innovative products, personnel and
            distribution systems. The Fund's portfolio managers may choose to
            sell a stock in the "growth" segment when they believe that its
            earnings will be disappointing or that market sentiment on the
            company will turn negative. The portfolio managers will also
            consider selling a stock if the company does not meet the
            managers' estimates on revenues and/or earnings, or if an
            alternative investment is deemed to be more attractive.

             When selecting securities for the Fund's "income" segment, the
            portfolio managers seek to identify companies with strong
            operating fundamentals that offer potential for capital
            appreciation and that also have a dividend yield in excess of the
            yield on the S&P 500 Index. The portfolio managers may replace an
            "income" security when another security with a similar risk-to-
            reward profile offers either better potential for capital
            appreciation or a higher yield than the Fund's current holding. To
            achieve its income objective, the Fund may also invest to a
            limited degree in preferred stocks, convertible securities and
            REITs. The Fund may invest up to 10% of its assets in corporate
            bonds, which will typically consist of investment grade securities
            of varying maturities but may also include high yield securities
            ("junk bonds") rated at least B by Standard & Poor's Rating
            Services or Moody's Investors Service, Inc. or, if unrated,
            determined by the Adviser to be of comparable quality.

             The Fund may invest up to 15% of its assets in foreign
            securities, except that it may invest without limit in American
            Depository Receipts (ADRs). The Fund has in the past invested a
            significant portion of its assets in technology or technology-
            related companies, although there is no assurance that it will
            continue to do so in the future. In response to unfavorable market
            and other conditions, the Fund may make temporary investments of
            some or all of its assets in high-quality fixed income securities.
            This would be inconsistent with the Fund's investment objective
            and principal strategies.

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 and the information to its
            right show performance of the Fund's Institutional Class Shares.
            During the periods shown, Administrative Class shares were
            outstanding only from 8/21/97 (the inception date of
            Administrative Class shares) to 5/27/99 (the date on which all
            Administrative Class shares then outstanding were redeemed). For
            periods prior to 8/21/97 and after 5/27/99, performance
            information shown in the Average Annual Total Returns table for
            Administrative Class shares is based on the performance of the
            Fund's Institutional Class shares, adjusted to reflect the actual
            distribution and/or service (12b-1) fees and other expenses paid
            by Administrative Class shares. The performance information on the
            next page for periods prior to August 1, 2000 reflects the Fund's
            advisory fee rate in effect prior to that date (0.63% per annum),
            which is higher than the current rate (0.60% per annum). Prior to
            July 1, 1999, the Fund had a different sub-adviser and would not
            necessarily have achieved the performance results shown on the
            next page under its current investment management arrangements.
            In addition, the Fund changed its investment objective and
            policies on August 1, 2000; the performance results shown on the
            next page would not necessarily have been achieved had the Fund's
            current objective and policies then been in effect. Past
            performance is no guarantee of future results.

            (1) The S&P Mid-Cap 400 Index is an unmanaged index of middle
                capitalization U.S. stocks. It is not possible to invest
                directly in the index.

            (2) The Lipper Large-Cap Core Funds Average is a total return
                performance average of funds tracked by Lipper Analytical
                Services, Inc. that invest primarily in companies with market
                capitalizations of greater than 300% of the dollar-weighted
                median market capitalization of the S&P Mid-Cap 400 Index.
                It does not take into account sales charges. The Lipper Large-
                Cap Core Funds Average replaced the Lipper Mid-Cap Funds
                Average (a total return performance average of funds tracked
                by Lipper Analytical Services, Inc. that invest primarily in
                companies with market capitalizations of less than $5 billion
                at the time of investment) because PIMCO Advisors believes the
                Large-Cap Core Funds Average is more representative of the
                Fund's investment strategies. For periods ended December 31,
                1999, the 1 Year, 5 Years and Fund Inception average annual
                total returns of the Lipper Mid-Cap Fund Average were 39.38%,
                23.07% and 23.07%, respectively.

            (1)  On August 1, 2000, the Fund's advisory fee rate decreased by
                 0.03%, to 0.60% per annum.
            (2)  Other Expenses reflects a 0.25% Administrative Fee paid by
                 each class and 0.15% in other expenses attributable to
                 Institutional Class shares during the most recent fiscal
                 year, and estimated to be attributable to Administrative
                 Class shares during the current fiscal year.

            Examples. The Examples below are intended to help you compare the
            cost of investing in Institutional Class or Administrative Class
            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 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.

</TABLE>

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of "growth"
            companies with market capitalizations of at least $5 billion at
            the time of investment.

             The portfolio manager selects stocks for the Fund using a
            "growth" style. The portfolio manager seeks to identify companies
            with well-defined "wealth creating" characteristics, including
            superior earnings growth (relative to companies in the same
            industry or the market as a whole), high profitability and
            consistent, predictable earnings. In addition, through fundamental
            research, the portfolio manager seeks to identify companies that
            are gaining market share, have superior management and possess a
            sustainable competitive advantage, such as superior or innovative
            products, personnel and distribution systems. The Fund looks to
            sell a stock when the portfolio manager believes that its
            earnings, market sentiment or relative performance are
            disappointing or if an alternative investment is more attractive.

             The Fund may also invest to a limited degree in other kinds of
            equity securities, including preferred stocks and convertible
            securities. The Fund may invest up to 15% of its assets in foreign
            securities, except that it may invest without limit in American
            Depository Receipts (ADRs). The Fund has in the past invested a
            significant portion of its assets in technology or technology-
            related companies, although there is no assurance that it will
            continue to do so in the future.

             In response to unfavorable market and other conditions, the Fund
            may make temporary investments of some or all of its assets in
            high-quality fixed income securities. This would be inconsistent
            with the Fund's investment objective and principal strategies.

Principal   Among the principal risks of investing in the Fund, which could

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 Class C shares, which are offered in a different
            prospectus. This is because the Fund has not offered Institutional
            Class or Administrative Class shares for a full calendar year.
            Although Class C, Institutional Class and Administrative Class
            shares would have similar annual returns (because all the Fund's
            shares represent interests in the same portfolio of securities),
            Class C performance would be lower than Institutional Class or
            Administrative Class performance because of the higher sales
            charges and expenses paid by Class C shares. The returns in the
            bar chart and the information to its right do not reflect the
            impact of sales charges (loads). If they did, the returns would be
            lower than those shown. Unlike the bar chart, performance figures
            for Class C shares in the Average Annual Total Returns table
            reflect the impact of sales charges. For periods prior to the
            inception of Institutional Class and Administrative Class shares
            (3/31/99), the Average Annual Total Returns table also shows
            estimated historical performance for Institutional Class and
            Administrative Class shares based on the performance of the Fund's
            Class C shares. The prior Class C performance has been adjusted to
            reflect that there are no sales charges and lower distribution
            and/or service (12b-1) fees (if any), administrative fees and
            other expenses paid by Institutional Class and Administrative
            Class shares. Prior to March 6, 1999, the Fund had a different
            sub-adviser and would not necessarily have achieved the
            performance results shown on the next page under its current
            investment management arrangements. Past performance is no
            guarantee of future results.

            Examples. The Examples below are intended to help you compare the
            cost of investing in Institutional Class or Administrative Class
            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 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 at least 65% of its assets in common stocks of "growth"
            companies with market capitalizations of at least $10 billion at
            the time of investment. The Fund normally invests in the
            securities of 15 to 25 issuers.

             The portfolio manager selects stocks for the Fund using a
            "growth" style. The portfolio manager seeks to identify companies
            with well-defined "wealth creating" characteristics, including
            superior earnings growth (relative to companies in the same
            industry or the market as a whole), high profitability and
            consistent, predictable earnings. In addition, through fundamental
            research, the portfolio manager seeks to identify companies that
            are gaining market share, have superior management and possess a
            sustainable competitive advantage, such as superior or innovative
            products, personnel and distribution systems. The Fund looks to
            sell a stock when the portfolio manager believes that its
            earnings, market sentiment or relative performance are
            disappointing or if an alternative investment is more attractive.
            The Fund is "non-diversified," which means that it invests in a
            relatively small number of issuers.

             The Fund may also invest to a limited degree in other kinds of
            equity securities, including preferred stocks and convertible
            securities. The Fund may invest up to 25% of its assets in foreign
            securities, except that it may invest without limit in American
            Depository Receipts (ADRs). The Fund has in the past invested a
            significant portion of its assets in technology or technology-
            related companies, although there is no assurance that it will
            continue to do so in the future. In response to unfavorable market
            and other conditions, the Fund may make temporary investments of
            some or all of its assets in high-quality fixed income securities.
            This would be inconsistent with the Fund's investment objective
            and principal strategies.

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

Performance
Information The top of the next page shows summary performance 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 and the information to its
            right show performance of the Fund's Institutional Class shares.
            For periods prior to the inception of Administrative Class shares
            (5/31/95), performance information shown in the Average Annual
            Total Returns table for that class is based on the performance of
            the Fund's Institutional Class shares. The prior Institutional
            Class performance has been adjusted to reflect the actual
            distribution and/or service (12b-1) fees and other expenses paid
            by Administrative Class shares. The performance information on the
            next page for periods prior to April 1, 2000 reflects the Fund's
            advisory fee rate in effect prior to that date (0.57% per annum);
            these results would have been lower had the current advisory fee
            rate (0.60% per annum) then been in effect. Prior to July 1, 1999,
            the Fund had a different sub-adviser and would not necessarily
            have achieved the performance results shown on the next page under
            its current investment management arrangements. In addition, the
            Fund changed its investment objective and policies on April 1,
            2000; the performance results shown on the next page would not
            necessarily have been achieved had the Fund's current objective
            and policies then been in effect. Past performance is no guarantee
            of future results.

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 Class A shares, which are offered in a different
            prospectus. This is because the Fund has not offered Institutional
            Class or Administrative Class shares for a full calendar year.
            Although Class A, Institutional Class and Administrative Class
            shares would have similar annual returns (because all the Fund's
            shares represent interests in the same portfolio of securities),
            Class A performance would be lower than Institutional Class or
            Administrative Class performance because of the higher sales
            charges and/or expenses paid by Class A shares. The returns in the
            bar chart and the information to its right do not reflect the
            impact of sales charges (loads). If they did, the returns would be
            lower than those shown. Unlike the bar chart, performance figures
            for Class A shares in the Average Annual Total Returns table
            reflect the impact of sales charges. For periods prior to the
            inception of Institutional Class and Administrative Class shares
            (3/31/99), the Average Annual Total Returns table also shows
            estimated historical performance for those classes based on the
            performance of the Fund's Class A shares. The Class A performance
            has been adjusted to reflect that there are no sales charges and
            lower administrative fees and other expenses paid by Institutional
            Class and Administrative Class shares (including no distribution
            and/or service (12b-1) fees paid by Institutional Class shares).
            Prior to March 6, 1999, Fund had a different sub-adviser and would
            not necessarily have achieved the performance results shown on the
            next page under its current investment management arrangements.
            Past performance is no guarantee of future results.

            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 the Fund's
            operating expenses remain the same. Although your actual costs may

                                   60-100

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of "growth"
            companies with market capitalizations of between $100 million and
            $2 billion at the time of investment.

             The portfolio manager selects stocks for the Fund using a
            "growth" style. The portfolio manager seeks to identify companies
            with well-defined "wealth creating" characteristics, including
            superior earnings growth (relative to companies in the same
            industry or the market as a whole), high profitability and
            consistent, predictable earnings. In addition, through fundamental
            research, the portfolio manager seeks to identify companies that
            are gaining market share, have superior management and possess a
            sustainable competitive advantage, such as superior or innovative
            products, personnel and distribution systems. The Fund looks to
            sell a stock when the portfolio manager believes that its
            earnings, market sentiment or relative performance are
            disappointing or if an alternative investment is more attractive.

             The Fund may also invest to a limited degree in other kinds of
            equity securities, including preferred stocks and convertible
            securities. The Fund may invest up to 15% of its assets in foreign
            securities, except that it may invest without limit in American
            Depository Receipts (ADRs). The Fund may invest a substantial
            portion of its assets in the securities of smaller capitalization
            companies and securities issued in initial public offerings
            (IPOs). The Fund has in the past invested a significant portion of
            its assets in technology or technology-related companies, although
            there is no assurance that it will continue to do so in the
            future.

             In response to unfavorable market and other conditions, the Fund
            may make temporary investments of some or all of its assets in
            high-quality fixed income securities. This would be inconsistent
            with the Fund's investment objective and principal strategies.

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 Class C shares, which are offered in a different
            prospectus. This is because the Fund has not offered Institutional
            Class or Administrative Class shares for a full calendar year.
            Although Class C, Institutional Class and Administrative Class
            shares would have similar annual returns (because all the Fund's
            shares represent interests in the same portfolio of securities),
            Class C performance would be lower than Institutional Class or
            Administrative Class performance because of the sales charges and
            higher expenses paid by Class C shares. The returns in the bar
            chart and the information to its right do not reflect the impact
            of sales charges (loads). If they did, the returns would be lower
            than those shown. Unlike the bar chart, performance figures for
            Class C shares in the Average Annual Total Returns table reflect
            the impact of sales charges. For periods prior to the inception of
            Institutional Class and Administrative Class shares (3/31/99), the
            Average Annual Total Returns table also shows estimated historical
            performance for those classes based on the performance of the
            Fund's Class C shares. The Class C performance has been adjusted
            to reflect that there are no sales charges and lower distribution
            and/or service (12b-1) fees (if any), administrative fees and
            other expenses paid by Institutional Class and Administrative
            Class shares. Prior to March 6, 1999, the Fund had a different
            sub-adviser and would not necessarily have achieved the
            performance results shown on the next page under its current
            investment management arrangements. Past performance is no

            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 normally
            investing at least 65% of its assets in common stocks of companies
            which utilize new, creative or different, or "innovative,"
            technologies to gain a strategic competitive advantage in their
            industry, as well as companies that provide and service those
            technologies. The Fund identifies its investment universe of
            technology-related companies primarily by reference to
            classifications made by independent firms, such as Standard &
            Poor's (for example, companies classified as "Information
            Technology" companies), and by identifying companies that derive a
            substantial portion of their revenues from the manufacture, sale
            and/or service of technological products. Although the Fund
            emphasizes companies which utilize technologies, it is not
            required to invest exclusively in companies in a particular
            business sector or industry.

             The portfolio manager selects stocks for the Fund using a
            "growth" style. The portfolio manager seeks to identify
            technology-related companies with well-defined "wealth creating"
            characteristics, including superior earnings growth (relative to
            companies in the same industry or the market as a whole), high
            profitability and consistent, predictable earnings. In addition,
            through fundamental research, the portfolio manager seeks to
            identify companies that are gaining market share, have superior
            management and possess a sustainable competitive advantage, such
            as superior or innovative products, personnel and distribution
            systems. The Fund looks to sell a stock when the portfolio manager
            believes that earnings or market sentiment are disappointing, if
            the company does not meet or exceed consensus estimates on
            revenues and/or earnings or if an alternative investment is more
            attractive.

             Although the Fund invests principally in common stocks, the Fund
            may also invest in other kinds of equity securities, including
            preferred stocks and convertible securities. The Fund may invest a
            substantial portion of its assets in the securities of smaller
            capitalization companies. The Fund may invest up to 15% of its
            assets in foreign securities, except that it may invest without
            limit in American Depository Receipts (ADRs). In response to
            unfavorable market and other conditions, the Fund may make
            temporary investments of some or all of its assets in high-quality
            fixed income securities. This would be inconsistent with the
            Fund's investment objective and principal strategies.

--------------------------------------------------------------------------------
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             .Smaller Company Risk    .Currency Risk
              .Issuer Risk             .Liquidity Risk          .Credit Risk
              .Focused Investment Risk .Foreign Investment Risk .Management Risk
              .Growth Securities Risk  .Technology Related 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 Class A shares, which are offered in a different
            prospectus. This is because the Fund has not offered Institutional
            Class or Administrative Class shares for a full calendar year.
            Although Class A, Institutional Class and Administrative Class
            shares would have similar returns (because all the Fund's shares
            represent interests in the same portfolio of securities), Class A
            performance would be lower than Institutional Class or
            Administrative Class performance because of the higher sales
            charges and/or expenses paid by Class A shares. The returns in the
            bar chart and the information to its right do not reflect the
            impact of sales charges (loads). If they did, the returns would be
            lower than those shown. Unlike the bar chart, performance figures
            for Class A shares in the Average Annual Total Returns table
            reflect the impact of sales charges. For periods prior to the
            inception of Institutional Class shares (3/5/99) and for all
            periods shown for Administrative Class shares (which were not
            offered during those periods), the Average Annual Total Returns
            table also shows estimated historical performance for those
            classes based on the performance of the Fund's Class A shares. The
            Class A performance has been adjusted to reflect that there are no
            sales charges and lower administrative fees and other expenses
            paid by Institutional Class and Administrative Class shares
            (including no distribution and/or service (12b-1) fees paid by
            Institutional Class shares). Prior to March 6, 1999, the Fund had
            a different sub-adviser and would not necessarily have achieved
            the performance results shown on the next page under its current
            investment management arrangements. Past performance is no
            guarantee of future results.

              The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of U.S. and
            non-U.S. companies which utilize new, creative or different, or
            "innovative," technologies to gain a strategic competitive
            advantage in their industry, as well as companies that provide and
            service those technologies. The Fund identifies its investment
            universe of technology-related companies primarily by reference to
            classifications made by independent firms, such as Standard &
            Poor's (for example, companies classified as "Information
            Technology" companies), and by identifying companies that derive a
            substantial portion of their revenues from the manufacture, sale
            and/or service of technological products. Although the Fund
            emphasizes companies which utilize technologies, it is not
            required to invest exclusively in a particular business sector or
            industry.

              The portfolio manager selects stocks for the Fund using a
            "growth" style. The portfolio manager seeks to identify
            technology-related companies with well-defined "wealth creating"
            characteristics, including superior earnings growth (relative to
            companies in the same industry or the market as a whole), high
            profitability and consistent, predictable earnings. In addition,
            through fundamental research, the portfolio manager seeks to
            identify companies that are gaining market share, have superior
            management and possess a sustainable competitive advantage, such
            as superior or innovative products, personnel and distribution
            systems. The Fund looks to sell a stock when the portfolio manager
            believes that earnings or market sentiment are disappointing, if
            the company does not meet or exceed consensus estimates on
            revenues and/or earnings or if an alternative investment is more
            attractive.

              Although the Fund invests principally in common stocks, the Fund
            may also invest in other types of equity securities, including
            preferred stocks and convertible securities. The Fund may invest a
            substantial portion of its assets in the securities of smaller
            capitalization companies and securities issued in initial public
            offerings (IPOs). The Fund will invest in the securities of
            issuers located in at least three countries (one of which may be
            the United States). Although the Fund invests primarily in
            securities traded principally in the securities markets of
            developed countries, the Fund has no other prescribed limits on
            geographic asset distribution and may invest in any foreign
            securities market in the world, including in developing, or
            "emerging," markets. The Fund may utilize foreign currency
            exchange contracts and derivative instruments (such as stock index
            futures contracts), primarily for risk management or hedging
            purposes.

              In response to unfavorable market and other conditions, the Fund
            may make temporary investments of some or all of its assets in
            high-quality fixed income securities. This would be inconsistent
            with the Fund's investment objective and principal strategies.

                PIMCO Advisors to waive, reduce or reimburse its
                Administrative Fees for each class in an amount that, in
                essence, is equal to the Fund's Organizational Expenses
                attributed to the class. Because the Organizational Expenses
                were accounted for in the Fund's initial fiscal year, the
                Fund's reasonable expectation is that the relevant conditions
                will not continue after the Fund's fiscal year ending June 30,
                2000.

                                   30-60

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in an international portfolio
            of common stocks and other equity securities of companies located
            outside of the United States. Although the Fund normally invests
            in issuers from at least five different countries, it may at times
            invest in fewer than five countries, or even a single country. The
            Fund typically invests in approximately 30 to 60 stocks. Although
            the Fund invests primarily in developed market countries, it may
            also invest in developing, or "emerging," markets. The Fund has no
            other limits on geographic asset distribution and may invest in
            any foreign securities market in the world. The Fund may also
            invest in securities of foreign issuers traded on U.S. securities
            markets, but will normally not invest in U.S. issuers. The Fund
            invests most of its assets in foreign securities which trade in
            currencies other than the U.S. dollar and may invest directly in
            foreign currencies.

             The portfolio managers select securities for the Fund using a
            research-driven "bottom-up" approach that seeks to utilize the
            Sub-Adviser's global research capabilities to identify companies
            with above-average long-term growth prospects and attractive
            valuations and that possess a sustainable competitive advantage,
            such as superior or innovative products, personnel and
            distribution systems. The portfolio manager seeks to select those
            stocks with the best long-term performance expectations, using a
            broad range of company fundamentals, such as long-term growth
            prospects, price-to-earnings ratios and other valuation measures,
            dividend and profit growth, balance sheet strength and return on
            assets. The portfolio managers sell stocks in order to adjust or
            rebalance the Fund's portfolio and to replace companies with
            weakening fundamentals.

             The Fund may invest a substantial portion of its assets in the
            securities of small and medium capitalization companies. The Fund
            may utilize foreign currency exchange contracts and derivative
            instruments (such as stock index futures contracts), primarily for
            portfolio management and hedging purposes. The Fund may to a
            limited degree invest in equity securities other than common
            stocks (such as equity-linked securities, preferred stocks and
            convertible securities) and may invest up to 10% of its assets in
            other investment companies. In response to unfavorable market and
            other conditions, the Fund may make temporary investments of some
            or all of its assets in foreign and domestic fixed income
            securities and in equity securities of U.S. issuers. This would be
            inconsistent with the Fund's investment objective and principal
            strategies.

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 and the information to its
            right show performance of the Fund's Institutional Class shares.
            The Fund's Administrative Class shares do not have a performance
            history for the time periods shown. Performance information shown
            in the Average Annual Total Returns table for Administrative Class
            shares is based on the performance of the Fund's Institutional
            Class shares, adjusted to reflect the actual distribution and/or
            service (12b-1) fees and other expenses paid by Administrative
            Class shares. The performance information on the next page for
            periods prior to May 8, 2000 reflects the Fund's advisory fee rate
            in effect prior to that date (0.85% per annum), which is higher
            than the current rate (0.75% per annum). Prior to November 1,
            2000, the Fund had different sub-advisers and would not
            necessarily have achieved the performance results shown on the
            next page under its current investment management arrangements. In
            addition, the Fund changed its investment objectives and policies
            on November 1, 2000; the performance results shown on the next
            page would not necessarily have been achieved had the Fund's
            current objectives and policies then been in effect. Past
            performance is no guarantee of future results.

                                                          At least annually

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of companies
            with very large market capitalizations that have improving
            fundamentals (based on growth criteria) and whose stock is
            reasonably valued by the market (based on value criteria).

             In making investment decisions for the Fund, the portfolio
            management team considers the 250 largest publicly traded
            companies (in terms of market capitalization) in the U.S. The team
            screens the stocks in this universe for a series of growth
            criteria, such as dividend growth, earnings growth, relative
            growth of earnings over time (earnings momentum) and the company's
            history of meeting earnings targets (earnings surprise), and also
            value criteria, such as price-to-earnings, price-to-book and
            price-to-cash flow ratios. The team then selects individual stocks
            by subjecting the top portion of the stocks in the screened
            universe to a rigorous analysis of company factors, such as
            strength of management, competitive industry position, and
            business prospects, and financial statement data, such as
            earnings, cash flows and profitability. The team may interview
            company management in making investment decisions. The Fund's
            capitalization criteria applies at the time of investment.

             The portfolio management team rescreens the universe frequently
            and seeks to consistently achieve a favorable balance of growth
            and value characteristics for the Fund. The team looks to sell a
            stock when it falls below the median ranking, has negative
            earnings surprises, or shows poor price performance relative to
            all stocks in the Fund's capitalization range or to companies in
            the same business sector. A stock may also be sold if its
            weighting in the portfolio becomes excessive (normally above 2% of
            the Fund's investments). The Fund has in the past invested a
            significant portion of its assets in technology or technology-
            related companies, although there is no assurance that it will
            continue to do so in the future.

             The Fund intends to be fully invested in common stock (aside from
            certain cash management practices) and will not make defensive
            investments in response to unfavorable market and other
            conditions.

            (1) Other Expenses reflects a 0.25% Administrative Fee paid by
                each class, 0.55% in organizational expenses ("Organizational
                Expenses") attributable to each class during the most recent
                fiscal year, and 0.01% in other expenses attributable to
                Institutional Class shares during the most recent fiscal year,
                and estimated to be attributable to Administrative Class
                shares during the current fiscal year.

            (2) Net Expenses reflect the effect of a contractual agreement by
                PIMCO Advisors to waive, reduce or reimburse its
                Administrative Fees for each class in an amount that, in
                essence, is equal to the Fund's Organizational Expenses
                attributed to the class. Because the Organizational Expenses
                were accounted for in the Fund's initial fiscal year, the
                Fund's reasonable expectation is that the relevant conditions
                will not continue after the Fund's fiscal year ending June 30,
                2000.

            by Administrative Class shares. Past performance is no guarantee
            of future results.

            Examples. The Examples below are intended to help you compare the
            cost of investing in Institutional Class or Administrative Class
            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 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.

</TABLE>
            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of companies
            with medium market capitalizations that have improving
            fundamentals (based on growth criteria) and whose stock is
            reasonably valued by the market (based on value criteria).

             In making investment decisions for the Fund, the portfolio
            management team considers companies in the U.S. market with market
            capitalizations of more than $500 million, but excluding the 200
            largest capitalization companies. The team screens the stocks in
            this universe for a series of growth criteria, such as dividend
            growth, earnings growth, relative growth of earnings over time
            (earnings momentum) and the company's history of meeting earnings
            targets (earnings surprise), and also value criteria, such as
            price-to-earnings, price-to-book and price-to-cash flow ratios.
            The team then selects individual stocks by subjecting the top 10%
            of the stocks in the screened universe to a rigorous analysis of
            company factors, such as strength of management, competitive
            industry position, and business prospects, and financial statement
            data, such as earnings, cash flows and profitability. The team may
            interview company management in making investment decisions. The
            Fund's capitalization criteria applies at the time of investment.

             The portfolio management team rescreens the universe frequently
            and seeks to consistently achieve a favorable balance of growth
            and value characteristics for the Fund. The team looks to sell a
            stock when it falls below the median ranking, has negative
            earnings surprises, or shows poor price performance relative to
            all stocks in the Fund's capitalization range or to companies in
            the same business sector. A stock may also be sold if its
            weighting in the portfolio becomes excessive (normally above 2% of
            the Fund's investments).

             The Fund intends to be fully invested in common stock (aside from
            certain cash management practices) and will not make defensive
            investments in response to unfavorable market and other
            conditions.

                                   60-100

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of companies
            with very small market capitalizations that have improving
            fundamentals (based on growth criteria) and whose stock is
            reasonably valued by the market (based on value criteria).

             In making investment decisions for the Fund, the portfolio
            management team considers companies in the U.S. market with market
            capitalizations less than $250 million. The team screens the
            stocks in this universe for a series of growth criteria, such as
            dividend growth, earnings growth, relative growth of earnings over
            time (earnings momentum) and the company's history of meeting
            earnings targets (earnings surprise), and also value criteria,
            such as price-to-earnings, price-to-book and price-to-cash flow
            ratios. The team then selects individual stocks by subjecting the
            top 10% of the stocks in the screened universe to a rigorous
            analysis of company factors, such as strength of management,
            competitive industry position, and business prospects, and
            financial statement data, such as earnings, cash flows and
            profitability. The team may interview company management in making
            investment decisions. The Fund's capitalization criteria applies
            at the time of investment.

             The portfolio management team rescreens the universe frequently
            and seeks to consistently achieve a favorable balance of growth
            and value characteristics for the Fund. The team looks to sell a
            stock when it falls below the median ranking, has negative
            earnings surprises, or shows poor price performance relative to
            all stocks in the Fund's capitalization range or to companies in
            the same business sector. A stock may also be sold if its
            weighting in the portfolio becomes excessive (normally above 3% of
            the Fund's investments). The Fund may invest a substantial portion
            of its assets in the securities of smaller capitalization
            companies and securities issued in initial public offerings
            (IPOs). The Fund has in the past invested a significant portion of
            its assets in technology or technology-related companies, although
            there is no assurance that it will continue to do so in the
            future.

             The Fund intends to be fully invested in common stock (aside from
            certain cash management practices) and will not make defensive
            investments in response to unfavorable market and other
            conditions.

            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 and the information to its

            For periods prior to the inception of Administrative Class shares
            (4/1/96), performance information shown in the Average Annual
            Total Returns table for that class is based on the performance of
            the Fund's Institutional Class shares. The prior Institutional
            Class performance has been adjusted to reflect the actual
            distribution and/or service (12b-1) fees and other expenses paid
            by Administrative Class shares. Past performance is no guarantee

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of companies
            with market capitalizations of between $100 million and $1.5
            billion at the time of investment and below average P/E ratios
            relative to the market and their respective industry groups. To
            achieve income, the Fund invests a portion of its assets in
            income-producing (e.g., dividend-paying) common stocks.

              The Fund's initial selection universe consists of approximately
            4,500 stocks of companies within the Fund's capitalization range.
            The portfolio managers screen this universe to identify
            approximately 500 undervalued stocks representing approximately
            160 industry groups. This screening process is based on a number
            of valuation factors, including P/E ratios (calculated both with
            respect to trailing operating earnings and forward earnings
            estimates) and price-to-sales, price-to-book value, and price-to-
            cash flow ratios. These factors are considered both on a relative
            basis (compared to other stocks in the same industry group) and on
            an absolute basis (compared to the overall market).

              From this narrowed universe, the portfolio managers select
            approximately 100 stocks for the Fund, each of which has close to
            equal weighting in the portfolio. They select stocks based on a
            quantitative analysis of factors including price momentum (based
            on changes in stock price relative to changes in overall market
            prices), earnings momentum (based on analysts' earnings per share
            estimates and revisions to those estimates), relative dividend
            yields and trading liquidity. The portfolio is also structured to
            have a maximum weighting of no more than 10% in any one industry.
            The portfolio managers may replace a stock if its market
            capitalization becomes excessive, if its valuation exceeds the
            average valuation of stocks represented in the S&P 500 Index, or
            when a stock within the same industry group has a considerably
            lower valuation than the Fund's current holding.

              Under normal circumstances, the Fund intends to be fully
            invested in common stocks (aside from certain cash management
            practices). The Fund may temporarily hold up to 10% of its assets
            in cash and cash equivalents for defensive purposes in response to
            unfavorable market and other conditions. This would be
            inconsistent with the Fund's investment objective and principal
            strategies.

              S&P 500 Index)     100-200
              that represents
              the performance
              of a reasonably
              broad spectrum
              of common stocks
              that are
              publicly traded
              in the U.S.



            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks represented
            in the S&P 500 Index.

             In making investment decisions for the Fund, the portfolio
            managers first rank the stocks in the S&P 500 Index using a
            quantitative model that analyses each stock's exposure to both
            growth factors (including company revenues and cash flows,
            reported and estimated earnings and earnings estimates revisions)
            and value factors (including relative stock price and price-to-
            earnings ratios). The rankings give more weight to stocks with
            rising earnings expectations where the stock price reflects
            reasonable valuation relative to other stocks in the same industry
            sector.

             Using these rankings, the portfolio managers construct a sector-
            neutral portfolio of between 100 to 200 stocks designed to have
            above-average total return potential relative to the S&P 500
            Index. The portfolio managers also use a computer optimization
            model to provide risk-controlled exposure to the S&P 500 Index,
            such that the portfolio ordinarily has no greater volatility than
            the index and provides diversification across the industry sectors
            represented in the index. The portfolio managers attempt to
            maintain this balance through frequent and modest restructuring of
            the portfolio. Generally, a stock is sold when it drops
            significantly in the portfolio managers' rankings or when a
            replacement is necessary to maintain the Fund's balance of risk
            relative to the S&P 500 Index.

             Notwithstanding these strategies, there is no assurance that the
            Fund's investment performance will equal or exceed that of the S&P
            500 Index.

             The Fund may invest in stocks of foreign issuers if included in
            the S&P 500. The Fund may change the index upon which it bases its
            performance without shareholder approval, although it does not
            expect to make such a change under ordinary circumstances.

             The Fund intends to be fully invested in common stock (aside from
            certain cash management practices) and will not make defensive
            investments in response to unfavorable market and other
            conditions.

            The Fund attempts to provide a total return which exceeds the
            return of the S&P 500 Index by investing in a broadly diversified
            portfolio of at least 200 common stocks. The Fund also attempts to
            achieve higher after-tax returns for its shareholders by using a
            variety of tax-efficient management strategies.

             The Fund seeks to achieve its investment objective by normally
            investing at least 95% of its assets in stocks represented in the
            S&P 500 Index. The Fund's portfolio is designed to have certain
            characteristics that are similar to those of the index, including
            such measures as dividend yield, P/E ratio, relative volatility,
            economic sector exposure, return on equity and market price-to-
            book value ratio. The Fund's return is intended to correlate
            highly with the return of the S&P 500 Index, but the portfolio
            managers attempt to produce a higher total return than the index
            by selecting a portion of the stocks represented in the index
            using the quantitative techniques described below. The portfolio
            managers also use these techniques to make sell decisions.
            Notwithstanding these strategies, there is no assurance that the
            Fund's investment performance will equal or exceed that of the S&P
            500 Index.

             The Fund intends to be fully invested in common stock (aside from
            certain cash management practices) and will not make defensive
            investments in response to unfavorable market and other
            conditions.

             Quantitative Techniques. The portfolio managers use a proprietary
            quantitative model that ranks companies based on long-term (5-10
            years) price appreciation potential. They analyze factors such as
            growth of sustainable earnings and dividend behavior. Stocks in
            the top 50% of the model's ranking are considered for purchase by
            the Fund. The Fund looks to sell stocks selected from the bottom
            20% of the model's ranking based on cost, current market value and
            anticipated benefit of replacement. The portfolio managers' sell
            discipline also focuses on reducing realized capital gains as
            indicated below.

             Tax-Efficient Strategies. The portfolio managers utilize a range
            of active tax management strategies designed to minimize the
            Fund's taxable distributions, including low portfolio turnover and
            favoring investments in low-dividend, growth-oriented companies.
            The portfolio managers also identify specific shares of stock to
            be sold that have the lowest tax cost. When prudent, stocks are
            also sold to realize capital losses in order to offset realized
            capital gains. In limited circumstances, the Fund may also
            distribute appreciated securities to shareholders to meet
            redemption requests so as to avoid realizing capital gains.
            Despite the use of these tax-efficient strategies, the Fund may
            realize gains and shareholders will incur tax liability from time
            to time.

Performance
Information The top of the next page shows summary performance 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 and the information to its
            right show performance of the Fund's Administrative Class shares.
            For periods prior to the inception of Institutional Class shares
            (7/2/99) and Administrative Class shares (9/30/98), performance
            information shown in the bar chart (including the information to
            its right) and in the Average Annual Total Returns table for those
            classes is based on the performance of the Fund's Class D shares,
            which are offered in a different prospectus. The prior Class D
            performance has been adjusted to reflect that there are lower
            administrative fees and other expenses paid by Institutional Class
            and Administrative Class shares (including no distribution and/or
            service (12b-1) fees paid by Institutional Class shares). Past
            performance is no guarantee of future results.

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of companies
            located in, or whose principal business operations are based in,
            emerging markets. The Fund is normally exposed to roughly 20
            emerging market countries and invests in more than 300 stocks. The
            Fund invests most of its assets in foreign securities which trade
            primarily in currencies other than the U.S. dollar and may also
            invest directly in foreign currencies.

             The International Finance Corporation Investable Composite Index
            is the primary source for identifying emerging market countries
            for the Fund. The portfolio managers may identify other emerging
            market countries on the basis of market capitalization and
            liquidity, as well their inclusion (or consideration for
            inclusion) as emerging market countries in other broad-based
            market indexes.

             The portfolio managers follow a disciplined and systematic
            investment process that emphasizes diversification and fairly
            consistent allocation among countries, industries and issuers.
            They select countries based on factors such as level of economic
            development (with emphasis on GNP per capita and local economic
            diversification) and the maturity of equity markets in the country
            (with emphasis on freedom of investment flows and development of
            legal, regulatory, banking and settlement systems). They assign
            equal weight to most countries represented in the portfolio unless
            the size of a country's equity market is prohibitive. Countries
            with smaller equity markets (i.e., less than $5 billion of market
            capitalization) are assigned one-half the weight of countries with
            larger equity markets. The portfolio managers divide all issuers
            in each eligible country into the following five broad economic
            sector groups: financial, industrial, consumer, utilities and
            natural resources. The Fund attempts to maintain exposure across
            all five sectors in each country. The portfolio managers purchase
            and sell individual stocks based on such factors as liquidity,
            industry representation, performance relative to industry and
            long-term profitability. A stock may also be sold when the
            portfolio managers believe its relative weighting in the portfolio
            has become excessive.

             Aside from certain cash management practices, the Fund intends to
            invest substantially all of its assets in common stocks and other
            equity and equity-linked securities (including preferred stocks
            and convertible securities) and will not make defensive
            investments in response to unfavorable market and other
            conditions. The Fund may use derivatives.

Performance Shown below is summary performance information for the Fund in a
Information 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 and the information to its right
            show performance of the Fund's Institutional Class shares, but the
            returns do not reflect the impact of a 1.00% Fund Reimbursement
            Fee charged both at the time of purchase and at the time of
            redemption. If they did, the returns would be lower than those
            shown. The Fund's Administrative Class shares do not have a
            performance history. Performance information shown in the Average
            Annual Total Returns table for Administrative Class shares is
            based on the performance of the Fund's Institutional Class shares,
            adjusted to reflect the actual distribution and/or service (12b-1)
            fees and other expenses paid by Administrative Class shares.
            Unlike the bar chart, performance figures for Institutional Class
            and Administrative Class shares in the Average Annual Total
            Returns table reflect the impact of Fund Reimbursement Fees. Past
            performance is no guarantee of future results.

            Examples: The Examples below are intended to help you compare the
            cost of investing in Institutional Class or Administrative Class
            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. The Examples also
            assume that your investment has a 5% return each year, the
            reinvestment of all dividends and distributions, and 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 at least 65% of its assets in common stocks of companies
            located in, or whose principal business operations are based in,
            emerging markets. The Fund is normally exposed to roughly 20
            emerging market countries and invests in more than 300 stocks. The
            Fund invests most of its assets in foreign securities which trade
            primarily in currencies other than the U.S. dollar and may also
            invest directly in foreign currencies.

             The International Finance Corporation Investable Composite Index
            is the primary source for identifying emerging market countries
            for the Fund. The portfolio managers may identify other emerging
            market countries on the basis of market capitalization and
            liquidity, as well their inclusion (or consideration for
            inclusion) as emerging market countries in other broad-based
            market indexes.

             The portfolio managers follow a disciplined and systematic
            investment process that emphasizes diversification and fairly
            consistent allocation among countries, industries and issuers.
            They select countries based on factors such as level of economic
            development (with emphasis on GNP per capita and local economic
            diversification) and the maturity of equity markets in the country
            (with emphasis on freedom of investment flows and development of
            legal, regulatory, banking and settlement systems). They assign
            equal weight to most countries represented in the portfolio unless
            the size of a country's equity market is prohibitive. Countries
            with smaller equity markets (i.e., less than $5 billion of market
            capitalization) are assigned one-half the weight of countries with
            larger equity markets. The portfolio managers divide all issuers
            in each eligible country into the following five broad economic
            sector groups: financial, industrial, consumer, utilities and
            natural resources. The Fund attempts to maintain exposure across
            all five sectors in each country. The portfolio managers purchase
            and sell individual stocks based on such factors as liquidity,
            industry representation, performance relative to industry and
            long-term profitability. A stock may also be sold when the
            portfolio managers believe its relative weighting in the portfolio
            has become excessive.

             Aside from certain cash management practices, the Fund intends to
            invest substantially all of its assets in common stocks and other
            equity and equity-linked securities (including preferred stocks
            and convertible securities) and will not make defensive
            investments in response to unfavorable market and other
            conditions. The Fund may use derivatives.

             Tax-Efficient Strategies. The portfolio managers utilize a range
            of active tax management strategies designed to minimize the
            Fund's taxable distributions, including low portfolio turnover and
            favoring investments in low-dividend, growth-oriented companies.
            The portfolio managers also identify specific shares of stock to
            be sold that have the lowest tax cost. When prudent, stocks are
            also sold to realize capital losses in order to offset realized
            capital gains. In limited circumstances, the Fund may also
            distribute appreciated securities to shareholders to meet
            redemption requests so as to avoid realizing capital gains.
            Despite the use of these tax-efficient strategies, the Fund may
            realize gains and shareholders will incur tax liability from time
            to time.

Performance Shown below is summary performance information for the Fund in a
Information 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 and the information to its right
            show performance of the Fund's Institutional Class shares, but the
            returns do not reflect the impact of a 1.00% Fund Reimbursement
            Fee charged both at the time of purchase and at the time of
            redemption. If they did, the returns would be lower than those
            shown. The Fund's Administrative Class shares do not have a
            performance history. Performance information shown in the Average
            Annual Total Returns table for Administrative Class shares is
            based on the performance of the Fund's Institutional Class shares,
            adjusted to reflect the actual distribution and/or service (12b-1)
            fees and other expenses paid by Administrative Class shares.
            Unlike the bar chart, performance figures for Institutional Class
            and Administrative Class shares in the Average Annual Total
            Returns table reflect the impact of Fund Reimbursement Fees. Past
            performance is no guarantee of future results.

            assume that your investment has a 5% return each year, the
            reinvestment of all dividends and distributions, and the Fund's
            operating expenses remain the same. Although your actual costs may

              is an incidental       200-250
              consideration

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in an international portfolio
            of common stocks, which may or may not pay dividends. The Fund
            normally invests in securities traded principally in developed
            foreign securities markets, but may also invest up to 30% of its
            assets in developing or "emerging" markets. The Fund has no
            prescribed limits on geographic asset distribution and may invest
            in any foreign securities market in the world. The Fund may also
            invest in securities of foreign issuers traded on U.S. securities
            markets, but will normally not invest in U.S. issuers. The Fund
            invests most of its assets in foreign securities which trade in
            currencies other than the U.S. dollar and may invest directly in
            foreign currencies.


              The portfolio manager uses a "top down" investment approach. He
            first determines regional and country weightings for the Fund by
            considering such factors as the condition and growth potential of
            the various economies and securities markets, currency and
            taxation considerations and other financial, social, national and
            political factors. The Sub-Adviser's country specialists then
            select individual stocks to fill out the desired country
            weightings. In selecting stocks, the specialists analyze a broad
            range of company fundamentals, such as price-to-earnings, price-
            to-book value and price-to-cash flow ratios (value factors),
            earnings, dividend and profit growth (growth factors) and balance
            sheet strength and return on assets (quality factors). The
            portfolio manager sells stocks in order to adjust or rebalance the
            Fund's regional and country weightings or to replace companies
            with weakening fundamentals.

              The Fund may utilize foreign currency exchange contracts and
            derivative instruments (such as stock index futures contracts)
            primarily for risk management or hedging purposes. The Fund may
            also invest in equity securities other than common stocks (such as
            preferred stocks and convertible securities) and may invest up to
            10% of its assets in other investment companies. In response to
            unfavorable market and other conditions, the Fund may make
            temporary investments of some or all of its assets in foreign and
            domestic fixed income securities and in equity securities of U.S.
            issuers. This would be inconsistent with the Fund's investment
            objective and principal strategies.

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 and the information to its
            right show performance of the Fund's Institutional Class shares.
            For periods prior to the inception of Institutional Class and
            Administrative Class shares (9/30/98), performance information
            shown in the bar chart (including the information to its right)
            and in the Average Annual Total Returns table for those classes is
            based on the performance of the Fund's Class C shares, which are
            offered in a different prospectus. The prior Class C performance
            has been adjusted to reflect the actual fees and expenses paid by
            Institutional Class and Administrative Class shares, including no

            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 summarized 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
            each 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.

Market      The market price of securities owned by a Fund may go up or down,
Risk        sometimes rapidly or unpredictably. Each of the Funds normally
            invests most of its assets in common stocks and/or other equity
            securities. A principal risk of investing in each Fund is that the
            equity securities in its portfolio will decline in value due to
            factors affecting equity securities markets generally or
            particular industries represented in those markets. The values of
            equity securities 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 also decline for a number of reasons
Risk        which directly relate to the issuer, such as management
            performance, financial leverage and reduced demand for the
            issuer's goods or services.

Value
Securities  Each Fund may invest in companies that may not be expected to
Risk        experience significant earnings growth, but whose securities its
            portfolio manager believes are selling at a price lower than their
            true value. The Equity Income, Value, Renaissance, Growth &
            Income, Allianz Select International, Mega-Cap, Capital
            Appreciation, Mid-Cap, Micro-Cap, Small-Cap Value, Enhanced
            Equity, Tax-Efficient Equity, Structured Emerging Markets, Tax-
            Efficient Structured Emerging Markets and International Funds may
            place particular emphasis on value securities. Companies that
            issue value securities may have experienced adverse business
            developments or may be subject to special risks that have caused
            their securities to be out of favor. If a portfolio manager's
            assessment of a company's prospects is wrong, or if the market
            does not recognize the value of the company, the price of its
            securities may decline or may not approach the value that the
            portfolio manager anticipates.

Growth
Securities  Each Fund may invest in equity securities of companies that its
Risk        portfolio manager believes will experience relatively rapid
            earnings growth. The Growth & Income, Growth, Select Growth,
            Target, Opportunity, Innovation, Global Innovation, Allianz Select
            International, Mega-Cap, Capital Appreciation, Mid-Cap, Micro-Cap,
            Enhanced Equity, Tax-Efficient Equity, Structured Emerging
            Markets, Tax-Efficient Structured Emerging Markets and
            International Funds may place particular emphasis on growth
            securities. Growth securities typically trade at higher multiples
            of current earnings than other securities. Therefore, the values
            of growth securities may be more sensitive to changes in current
            or expected earnings than the values of other securities.

Smaller
Company
Risk
            The general risks associated with equity securities and liquidity
            risk are particularly pronounced for securities of companies with
            smaller market capitalizations. These companies may have limited
            product lines, markets or financial resources or they may depend
            on a few key employees. Securities of smaller companies may trade
            less

49   PIMCO Funds: Multi-Manager Series
<PAGE>


            frequently and in lesser volume than more widely held securities
            and their values may fluctuate more sharply than other securities.
            They may also trade in the over-the-counter market or on a
            regional exchange, or may otherwise have limited liquidity. The
            Micro-Cap Fund, in particular, and the Innovation, Global
            Innovation, Opportunity and Small-Cap Value Funds generally have
            substantial exposure to this risk. The Growth & Income, Target,
            Allianz Select International and Mid-Cap Funds also have
            significant exposure to this risk because they invest substantial
            assets in companies with medium-sized market capitalizations,
            which are smaller and generally less-seasoned than the largest
            companies.

IPO Risk    The Funds, particularly the Global Innovation Fund, may purchase
            securities in initial public offerings (IPOs). These securities
            are subject to many of the same risks as investing in companies
            with smaller market capitalizations. Securities issued in IPOs
            have no trading history, and information about the companies may
            be available for very limited periods. In addition, the prices of
            securities sold in IPOs may be highly volatile. At any particular
            time or from time to time a Fund may not be able to invest in
            securities issued in IPOs, or invest to the extent desired,
            because, for example, only a small portion (if any) of the
            securities being offered in an IPO may be made available to the
            Fund. In addition, under certain market conditions a relatively
            small number of companies may issue securities in IPOs. Similarly,
            as the number of Funds to which IPO securities are allocated
            increases, the number of securities issued to any one Fund may
            decrease. The investment performance of a Fund during periods when
            it is unable to invest significantly or at all in IPOs may be
            lower than during periods when the Fund is able to do so. In
            addition, as a Fund increases in size, the impact of IPOs on the
            Fund's performance will generally decrease.

Liquidity   All of the Funds are subject to liquidity risk. Liquidity risk
Risk        exists when particular investments are difficult to purchase or
            sell, possibly preventing a Fund from selling such illiquid
            securities at an advantageous time or price. Funds with principal
            investment strategies that involve securities of companies with
            smaller market capitalizations, foreign securities, derivatives or
            securities with substantial market and/or credit risk tend to have
            the greatest exposure to liquidity risk.

Derivatives All Funds except the Mega-Cap, Capital Appreciation, Mid-Cap,
Risk        Micro-Cap and Small-Cap Value Funds may use derivatives, which are
            financial contracts whose 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
            may sometimes use derivatives 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, which
            increases opportunities for gain but also involves greater risk of
            loss due to 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, 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. In addition, a
            Fund's use of derivatives may increase or accelerate the amount of
            taxes payable by shareholders. 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.

Sector
Specific
Risks
            In addition to other risks, Funds that invest a substantial
            portion of their assets in related industries (or "sectors") may
            have greater risk because companies in these sectors may share
            common characteristics and may react similarly to market
            developments.

                                                                   Prospectus 50
<PAGE>


            Technology Related Risk. Because the Global Innovation and
            Innovation Funds concentrate their investments in companies which
            utilize innovative technologies, they are subject to risks
            particularly affecting those companies, such as the risks of short
            product cycles and rapid obsolescence of products and services,
            competition from new and existing companies, signficant losses
            and/or limited earnings, security price volatility and limited
            operating histories. Other Funds may also be subject to these
            risks to the extent they invest their assets in technology or
            technology-related companies.

Foreign
(non-       A Fund that invests in foreign securities, and particularly the
U.S.)       Global Innovation, Allianz Select International, Structured
Investment  Emerging Markets, Tax-Efficient Structured Emerging Markets and
Risk        International Funds, may experience more rapid and extreme changes
            in value than Funds that invest exclusively in securities of U.S.
            issuers or securities that trade exclusively in U.S. markets. The
            securities markets of many foreign countries are relatively small,
            with a 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. To the extent that a Fund, such as the Global
            Innovation, Allianz Select International, Structured Emerging
            Markets, Tax-Efficient Structured Emerging Markets or
            International Fund, invests a significant portion of its assets in
            a narrowly defined geographic area such as Europe, Asia or South
            America, the Fund will generally have more exposure to regional
            economic risks associated with foreign investments. Adverse
            conditions in certain regions (such as Southeast Asia) can also
            adversely affect securities of other countries whose economies
            appear to be unrelated. In addition, special U.S. tax
            considerations may apply to a Fund's investment in foreign
            securities.

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. The Structured Emerging
            Markets and Tax-Efficient Structured Emerging Markets Funds
            normally invest most of their assets in emerging market securities
            and are particularly sensitive to these risks. The Global
            Innovation, Allianz Select International and International Funds
            may also invest a significant portion of their assets in emerging
            market securities. In addition, the risks associated with
            investing in a narrowly defined geographic area (discussed above
            under "Foreign (non-U.S.) Investment Risk") are generally more
            pronounced with respect to investments in emerging market
            countries.

Currency
Risk        Funds that invest directly in foreign currencies or in securities
            that trade in, and receive revenues in, foreign 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. The Global Innovation, Allianz Select
            International, Structured Emerging Markets, Tax-Efficient
            Structured Emerging Markets and International Funds are
            particularly sensitive to currency risk. 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.

Focused
Investment
Risk

            Focusing Fund investments in a small number of issuers, industries
            or foreign currencies or regions increases risk. Funds, such as
            the Select Growth Fund, that are "non-diversified" because they
            invest in a relatively small number of
            issuers may have more risk because changes in the value of a
            single security or the impact of a single economic, political or
            regulatory occurrence may have a greater adverse impact on the
            Fund's net asset value. Some of those

51 PIMCO Funds: Multi-Manager Series

            issuers also may present substantial credit or other risks. The
            Global Innovation, Allianz Select International, Structured
            Emerging Markets, Tax-Efficient Structured Emerging Markets and
            International Funds may be subject to increased risk to the extent
            that they focus their investments in securities denominated in a
            particular foreign currency or in a narrowly defined geographic
            area outside the U.S., because companies in those areas may share
            common characteristics and are often subject to similar business
            risks and regulatory burdens, and their securities may react
            similarly to economic, market, political or other developments.
            Similarly, the Innovation and Global Innovation Funds are
            vulnerable to events affecting companies which use innovative
            technologies to gain a strategic, competitive advantage in their
            industry and companies that provide and service those technologies
            because these funds normally "concentrate" their investments in
            those companies. Also, the Funds may from time to time have
            greater risk to the extent they invest a substantial portion of
            their assets in companies in related industries such as
            "technology" or "financial and business services," which may share
            common characteristics, are often subject to similar business
            risks and regulatory burdens, and whose securities may react
            similarly to economic, market, political or other developments.

Leveraging  Leverage, including borrowing, will cause the value of a Fund's
Risk        shares to be more volatile than if the Fund did not use leverage.
            This is because leverage tends to exaggerate the effect of any
            increase or decrease in the value of a Fund's portfolio
            securities. The Funds, and in particular the Global Innovation,
            Enhanced Equity, Tax-Efficient Equity, Structured Emerging
            Markets, Tax-Efficient Structured Emerging Markets and
            International Funds, may engage in transactions or purchase
            instruments that give rise to forms of leverage. Such transactions
            and instruments may include, among others, the use of reverse
            repurchase agreements and other borrowings, the investment of
            collateral from loans of portfolio securities, or the use of when-
            issued, delayed-delivery or forward commitment transactions. The
            use of derivatives may also involve leverage. The use of leverage
            may also cause a Fund to liquidate portfolio positions when it
            would not be advantageous to do so in order to satisfy its
            obligations or to meet segregation requirements.

Interest    To the extent that Funds purchase fixed income securities for
Rate Risk   investment or defensive purposes, they will be subject to interest
            rate risk, a market risk relating to investments in fixed income
            securities such as bonds and notes. The Growth & Income Fund is
            particularly sensitive to this risk because it may invest in
            interest rate sensitive securities such as corporate bonds.

            As interest rates rise, the value of fixed income securities in a
            Fund's portfolio are likely to decrease. Securities with longer
            "durations" (defined below) tend to be more sensitive to changes
            in interest rates, usually making them more volatile than
            securities with shorter durations. 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. Generally, 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      All of the Funds are subject to credit risk. This is the risk that
Risk        the issuer or the guarantor of a fixed 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 their credit ratings.

High
Yield       Funds that invest in high yield securities and unrated securities
Risk        of similar quality (commonly known as "junk bonds") may be subject
            to greater levels of interest rate, credit and liquidity risk than
            Funds that do not invest in such securities. The Growth & Income
            Fund is particularly susceptible to this risk. These securities
            are considered predominantly 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 these securities and reduce
            a Fund's ability to sell them.

Management
Risk
            Each Fund is subject to management risk because it is an actively
            managed investment portfolio. PIMCO Advisors, the Sub-Advisers 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.

Investment
Adviser
and
Administrator
            PIMCO Advisors serves as the investment adviser and the
            administrator (serving in its capacity as administrator, the
            "Administrator") for the Funds. Subject to the supervision of the
            Board of Trustees, PIMCO Advisors is responsible for managing,
            either directly or through others selected by it, the investment
            activities of the Funds and the Funds' business affairs and other
            administrative matters.

             PIMCO Advisors is located at 800 Newport Center Drive, Newport
            Beach, California 92660. Organized in 1987, PIMCO Advisors
            provides investment management and advisory services to private
            accounts of institutional and individual clients and to mutual
            funds. As of September 30, 2000, PIMCO Advisors and its subsidiary
            partnerships had approximately $272 billion in assets under
            management.

             PIMCO Advisors has retained investment management firms ("Sub-
            Advisers") to manage each Fund's investments, except that the
            PIMCO Equity Advisors division of PIMCO Advisors manages the
            investments of the Equity Income, Value, Renaissance, Growth &
            Income, Growth, Select Growth, Target, Opportunity, Innovation and
            Global Innovation Funds. (PIMCO Equity Advisors is also referred
            to as a "Sub-Adviser" in this capacity.) See "Sub-Advisers" below.

             PIMCO Advisors has retained its affiliate, Pacific Investment
            Management Company LLC ("Pacific Investment Management Company"),
            to provide various administrative and other services required by
            the Funds in its capacity as sub-administrator. PIMCO Advisors and
            the sub-administrator may retain other affiliates to provide
            certain of these services.

Advisory    Each Fund pays PIMCO Advisors fees in return for providing or
Fees        arranging for the provision of investment advisory services. In
            the case of Funds for which PIMCO Advisors has retained a separate
            Sub-Adviser, PIMCO Advisors (and not the Fund) pays a portion of
            the advisory fees it receives to the Sub-Adviser in return for its
            services.

             For the fiscal year ended June 30, 2000, the Funds paid monthly
            advisory fees to PIMCO Advisors at the following annual rates
            (stated as a percentage of the average daily net assets of each
            Fund taken separately):

Administrative
Fees

            Each Fund pays for the administrative services it requires under a
            fee structure which is essentially fixed. Institutional and
            Administrative Class shareholders of each Fund pay an
            administrative fee to PIMCO Advisors, computed as a percentage of
            the Fund's assets attributable in the aggregate to those classes
            of shares. PIMCO Advisors, in turn, provides or procures
            administrative services for Institutional and Administrative Class
            shareholders and also bears the costs of most third-party services
            required by the Funds, including audit, custodial, portfolio
            accounting, legal, transfer agency and printing costs. The Funds
            do bear other expenses which are not covered under the
            administrative fee which may vary and affect the total level of
            expenses paid by Institutional and Administrative Class
            shareholders, such as brokerage fees, commissions and other
            transaction expenses, costs of borrowing money, including interest
            expenses, and fees and expenses of the Trust's disinterested
            Trustees.

             Institutional and Administrative Class shareholders of the Funds
            pay PIMCO Advisors monthly administrative fees at the following

Blairlogie
            Blairlogie provides advisory services to mutual funds and
            institutional accounts. Blairlogie Capital Management Ltd., the
            predecessor investment adviser to Blairlogie, commenced operations
            in 1992. Accounts managed by Blairlogie had combined assets as of
            September 30, 2000 of approximately $1.0 billion.

             Blairlogie is an indirect majority-owned subsidiary of the
            Alleghany Corporation, and is not an affiliate of PIMCO Advisors.
            Blairlogie was formerly an affiliated sub-partnership of PIMCO
            Advisors. On April 30, 1999, PIMCO Advisors sold all of its
            ownership interest in Blairlogie to subsidiaries of the Alleghany
            Corporation. PIMCO Advisors retained Blairlogie as the Sub-Adviser
            of the International Fund both prior and subsequent to this
            transaction.

            The following individual at Blairlogie has primary responsibility
            for the International Fund.

Adviser/Sub-Adviser
Relationship

            Shareholders of each Fund (except the Innovation, Mid-Cap and
            Micro-Cap Funds) have approved a proposal permitting PIMCO
            Advisors to enter into new or amended sub-advisory agreements with
            one or more sub-advisers with respect to each Fund without
            obtaining shareholder approval of such agreements, subject to the
            conditions of an exemptive order that has been granted by the
            Securities and Exchange Commission. One of the conditions requires
            the Board of Trustees to approve any such agreement. In addition,
            the exemptive order prohibits PIMCO Advisors from entering into
            sub-advisory agreements with affiliates of PIMCO Advisors without
            shareholder approval, unless those affiliates are substantially
            wholly-owned by PIMCO Advisors. PIMCO Advisors has the ultimate
            responsibility to oversee the Sub-Advisers and to recommend their
            hiring, termination and replacement.

Distributor The Trust's Distributor is PIMCO Funds Distributors LLC, 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.

                                                                   Prospectus 58


<PAGE>

            Investment Options --
            Institutional Class and Administrative Class Shares

            The Trust offers investors Institutional Class and Administrative
            Class shares of the Funds in this Prospectus.

             The Trust does not charge any sales charges (loads) or other fees
            in connection with purchases, sales (redemptions) or exchanges of
            Institutional Class or Administrative Class shares, except that a
            1.00% Fund Reimbursement Fee may apply to transactions involving
            shares of the Structured Emerging Markets and Tax-Efficient
            Structured Emerging Markets Funds. See "Purchases, Redemptions and
            Exchanges--Fund Reimbursement Fees" below.

             Administrative Class shares are generally subject to a higher
            level of operating expenses than Institutional Class shares due to
            the additional service and/or distribution fees paid by
            Administrative Class shares as described below. Therefore,
            Institutional Class shares will generally pay higher dividends and
            have a more favorable investment return than Administrative Class
            shares.

              . Service and Distribution (12b-1) Fees--Administrative Class
            Shares. The Trust has adopted an Administrative Services Plan for
            the Administrative Class shares of each Fund. It has also adopted
            a Distribution Plan for the Administrative Class shares of each
            Fund. Each Plan has been adopted in accordance with the
            requirements of Rule 12b-1 under the Investment Company Act of
            1940 and is administered in accordance with that rule. However,
            shareholders do not have the voting rights set forth in Rule 12b-1
            with respect to the Administrative Services Plan.

             Each Plan allows the Funds to use its Administrative Class assets
            to reimburse financial intermediaries that provide services
            relating to Administrative Class shares. The Distribution Plan
            permits reimbursement for expenses in connection with the
            distribution and marketing of Administrative Class shares and/or
            the provision of shareholder services to Administrative Class
            shareholders. The Administrative Services Plan permits
            reimbursement for services in connection with the administration
            of plans or programs that use Administrative Class shares of the
            Funds as their funding medium and for related expenses.

             In combination, the Plans permit a Fund to make total
            reimbursements at an annual rate of up to 0.25% of the Fund's
            average daily net assets attributable to its Administrative Class
            shares. The same entity may not receive both distribution and
            administrative services fees with respect to the same
            Administrative Class assets, but may receive fees under each Plan
            with respect to separate assets. Because these fees are paid out
            of a Fund's Administrative Class assets on an ongoing basis, over
            time they will increase the cost of an investment in
            Administrative Class shares and may cost an investor more than
            other types of sales charges.

              . Arrangements with Service Agents. Institutional Class and
            Administrative Class shares of the Funds may 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 and/or
            distribution fees paid with respect to Administrative Class
            shares. Service agents may impose additional or different
            conditions than the Trust on purchases, redemptions or exchanges
            of Fund shares by their customers. Service agents may also
            independently establish and charge their customers transaction
            fees, account fees and other amounts in connection with purchases,
            sales and redemptions of Fund shares in addition to any fees
            charged by the Trust. These additional fees may vary over time and
            would increase the cost of the customer's investment and lower
            investment returns. 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, redemptions and exchanges. Shareholders who
            are customers of service agents should consult their service
            agents for information regarding these fees and conditions.

            Purchases, Redemptions and Exchanges

Purchasing  Investors may purchase Institutional Class and Administrative
Shares      Class shares of the Funds at the relevant net asset value ("NAV")
            of that class without a sales charge or other fee, except that a
            1.00% Fund Reimbursement Fee may apply to transactions involving
            shares of the Structured Emerging Markets and Tax-Efficient
            Structured Emerging Markets Funds. See "Fund Reimbursement Fees"
            below.

             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 their
            customers' investments in the Funds.

             Administrative Class shares are offered primarily through
            employee benefit plan alliances, broker-dealers and other
            intermediaries, and each Fund pays service and/or distribution
            fees to these entities for services they provide to Administrative
            Class shareholders.

             Pension and profit-sharing plans, employee benefit trusts and
            employee benefit plan alliances and "wrap account" programs
            established with broker-dealers or financial intermediaries may
            purchase shares of either class only if the plan or program for
            which the shares are being acquired will maintain an omnibus or
            pooled account for each Fund and will not require a Fund to pay
            any type of administrative payment per participant account to any
            third party.

              . Investment Minimums. The minimum initial investment for shares
            of either class is $5 million, except that the minimum initial
            investment for a registered investment adviser purchasing
            Institutional Class shares for its clients through omnibus
            accounts is $250,000 per Fund. At the discretion of PIMCO
            Advisors, the minimum initial investment may be waived for
            Institutional or Administrative Class shares offered to clients of
            PIMCO Equity Advisors, PAIA Cadence, NFJ, Pacific Investment
            Management Company, Parametric, and their affiliates, and to the
            benefit plans of PIMCO Advisors and its affiliates. In addition,
            the minimum initial investment does not apply to Institutional
            Class shares offered through fee-based programs sponsored and
            maintained by a registered broker-dealer and approved by the
            Distributor in which each investor pays an asset based fee at an
            annual rate of at least 0.50% of the assets in the account to a
            financial intermediary for investment advisory and/or
            administrative services.

             The Trust and the Distributor may waive the minimum initial
            investment for other categories of investors at their discretion.

             The investment minimums discussed in this section and the
            limitations set forth in "Investment Limitations" below do not
            apply to participants in PIMCO Advisors Portfolio Strategies, a
            managed product sponsored by PIMCO Advisors.

              . Timing of Purchase Orders and Share Price Calculations. A
            purchase order received by the Trust's transfer agent, National
            Financial Data Services (the "Transfer Agent"), prior to the close
            of regular trading (normally 4:00 p.m., Eastern time) on the New
            York Stock Exchange, on a day the Trust is open for business,
            together with payment made in one of the ways described below,
            will be effected at that day's net asset value ("NAV"). An order
            received after the close of regular trading on the New York Stock
            Exchange will be effected at the NAV determined on the next
            business day. However, orders received by certain retirement plans
            and other financial intermediaries on a business day prior to the
            close of regular trading on the New York Stock Exchange and
            communicated to the Transfer Agent prior to 9:00 a.m., Eastern
            time, on the following business day will be effected at the NAV
            determined on the prior business day. The Trust is "open for
            business" on each day the New York Stock Exchange is open for
            trading, which excludes the following holidays: New Year's Day,
            Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
            Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
            Christmas Day. Purchase orders will be accepted only on days on
            which the Trust is open for business.

                                                                   Prospectus 60

              . Initial Investment. Investors may open an account by
            completing and signing a Client Registration Application and
            mailing it to PIMCO Funds at 840 Newport Center Drive, Suite 300,
            Newport Beach, California 92660. A Client Registration Application
            may be obtained by calling 1-800-927-4648.

             Except as described below, an investor may purchase Institutional
            Class and Administrative Class shares only by wiring federal funds
            to the Transfer Agent, National Financial Data Services, 330 West
            9th Street, 4th Floor, Kansas City, Missouri 64105. Before wiring
            federal funds, the investor must telephone the Trust at 1-800-927-
            4648 to receive instructions for wire transfer and must provide
            the following information: name of authorized person, shareholder
            name, shareholder account number, name of Fund and share class,
            amount being wired, and wiring bank name.

             An investor may purchase shares without first wiring federal
            funds if the proceeds of the investment are derived from an
            advisory account the investor maintains with PIMCO Advisors or one
            of its affiliates, from surrender or other payment from an
            annuity, insurance, or other contract held by Pacific Life
            Insurance Company LLC, or from an investment by broker-dealers,
            institutional clients or other financial intermediaries which have
            established a shareholder servicing relationship with the Trust on
            behalf of their customers.

              . Additional Investments. An investor may purchase additional
            Institutional Class and Administrative Class shares of the Funds
            at any time by calling the Trust and wiring federal funds to the
            Transfer Agent as outlined above.

              . Other Purchase Information. Purchases of a Fund's
            Institutional Class and Administrative Class shares will be made
            in full and fractional shares. In the interest of economy and
            convenience, certificates for shares will not be issued.

             The Trust and the Distributor each reserves the right, in its
            sole discretion, to suspend the offering of shares of the Funds or
            to reject any purchase order, in whole or in part, when, in the
            judgment of management, such suspension or rejection is in the
            best interests of the Trust.

             An investor should invest in the Funds for long-term investment
            purposes only. The Trust and PIMCO Advisors each reserves the
            right to restrict purchases of Fund shares (including exchanges)
            when a pattern of frequent purchases and sales made in response to
            short-term fluctuations in share price appears evident. Notice of
            any such restrictions, if any, will vary according to the
            particular circumstances.

             Institutional Class and Administrative Class shares of the Trust
            may not be qualified or registered for sale in all states.
            Investors should inquire as to whether shares of a particular Fund
            are available for offer and sale in the investor's state of
            residence. Shares of the Trust may not be offered or sold in any
            state unless registered or qualified in that jurisdiction or
            unless an exemption from registration or qualification is
            available.

             Subject to the approval of the Trust, an investor may purchase
            shares of a Fund with liquid securities that are eligible for
            purchase by the Fund (consistent with the Fund's investment
            policies and restrictions) and that have a value that is readily
            ascertainable in accordance with the Trust's valuation policies.
            These transactions will be effected only if PIMCO Advisors or a
            Sub-Adviser intends to retain the security in the Fund as an
            investment. Assets purchased by a Fund in such a transaction will
            be valued in generally the same manner as they would be valued for
            purposes of pricing the Fund's shares, if such assets were
            included in the Fund's assets at the time of purchase. The Trust
            reserves the right to amend or terminate this practice at any
            time.

              . Retirement Plans. Shares of the Funds are available for
            purchase by retirement and savings plans, including Keogh plans,
            401(k) plans, 403(b) custodial accounts, and Individual Retirement
            Accounts. The administrator of a plan or employee benefits office
            can provide participants or employees with detailed information on
            how to participate in the plan and how to elect a Fund as an
            investment option. Participants in a retirement or savings plan
            may be permitted to elect different investment options, alter the
            amounts

            contributed to the plan, or change how contributions are allocated
            among investment options in accordance with the plan's specific
            provisions. The plan administrator or employee benefits office
            should be consulted for details. For questions about participant
            accounts, participants should contact their employee benefits
            office, the plan administrator, or the organization that provides
            recordkeeping services for the plan. Investors who purchase shares
            through retirement plans should be aware that plan administrators
            may aggregate purchase and redemption orders for participants in
            the plan. Therefore, there may be a delay between the time the
            investor places an order with the plan administrator and the time
            the order is forwarded to the Transfer Agent for execution.

              . Fund Reimbursement Fees. Investors in Institutional Class and
            Administrative Class shares of the Structured Emerging Markets and
            Tax-Efficient Structured Emerging Markets Funds are subject to a
            "Fund Reimbursement Fee," both at the time of purchase and at the
            time of redemption, equal to 1.00% of the net asset value of the
            shares purchased or redeemed. Fund Reimbursement Fees are not paid
            separately, but are deducted automatically from the amount
            invested or the amount to be received in connection with a
            redemption. Fund Reimbursement Fees are paid to and retained by
            the Funds to defray certain costs described below and are not paid
            to or retained by PIMCO Advisors, the Fund's Sub-Adviser, or the
            Distributor. Fund Reimbursement Fees are not sales loads or
            contingent deferred sales charges. Reinvestment of dividends and
            capital gains distributions paid to shareholders by the Funds are
            not subject to Fund Reimbursement Fees, but redemptions and
            exchanges of shares acquired by these reinvestments are subject to
            Fund Reimbursement Fees unless a waiver applies.

             The purpose of the Fund Reimbursement Fees is to defray the costs
            associated with investing the proceeds of the sale of the Fund's
            shares (in the case of purchases) or the costs associated with the
            sale of portfolio securities to satisfy redemption requests (in
            the case of redemptions), thereby insulating existing shareholders
            from such costs. The amount of a Fund Reimbursement Fee represents
            the Sub-Adviser's estimate of the costs reasonably anticipated to
            be incurred by the Funds in connection with the purchase or sale
            of portfolio securities, including international stocks,
            associated with an investor's purchase or redemption. These costs
            include brokerage costs, market impact costs (i.e., the increase
            in market prices which may result when a Fund purchases or sells
            thinly traded stocks) and the effect of "bid/asked" spreads in
            international markets. Transaction costs incurred when purchasing
            or selling stocks of companies in foreign countries, and
            particularly emerging market countries, may be significantly
            higher than those in more developed countries. This is due, in
            part, to less competition among brokers, underutilization of
            technology on the part of foreign exchanges and brokers, the lack
            of less expensive investment options (such as derivative
            instruments) and lower levels of liquidity in foreign and
            underdeveloped markets.

             Waiver of Fund Reimbursement Fees. Former participants in the
            Parametric Portfolio Associates Emerging Markets Trust will not be
            subject to Fund Reimbursement Fees with respect to any shares of
            the Structured Emerging Markets and Tax-Efficient Structured
            Emerging Markets Funds they acquired through June 30, 1998, and
            will not be subject to Fund Reimbursement Fees upon the subsequent
            redemption (including any redemption in connection with an
            exchange) of any shares acquired by any such participant through
            June 30, 1998. Such participants will be subject to such Fund
            Reimbursement Fees to the same extent as any other shareholder on
            any shares of either Fund acquired (whether by reinvestment of
            dividends or capital gain distributions or otherwise) after June
            30, 1998.

Redeeming
Shares
              . Redemptions by Mail. An investor may redeem (sell)
            Institutional Class and Administrative Class shares by submitting
            a written request to PIMCO Funds at 840 Newport Center Drive,
            Suite 300, Newport Beach, California 92660. The redemption request
            should state the Fund from which the shares are to be redeemed,
            the class of shares, the number or dollar amount of the shares to
            be redeemed and the account number. The request must be signed
            exactly as the names of the registered owners appear on the
            Trust's account records,

                                                                   Prospectus 62
<PAGE>

            and the request must be signed by the minimum number of persons
            designated on the Client Registration Application that are
            required to effect a redemption.

              . Redemptions by Telephone or Other Wire Communication. An
            investor that elects this option on the Client Registration
            Application (or subsequently in writing) may request redemptions
            of shares by calling the Trust at 1-800-927-4648, by sending a
            facsimile to 1-949-725-6830, by sending an e-mail to
            [email protected] or by other means of wire
            communication. Investors should state the Fund and class from
            which the shares are to be redeemed, the number or dollar amount
            of the shares to be redeemed, the account number and the signature
            (which may be an electronic signature) of an authorized signatory.
            Redemption requests of an amount of $10 million or more may be
            initiated by telephone or e-mail, but must be confirmed in writing
            by an authorized party prior to processing.

             In electing a telephone redemption, the investor authorizes
            Pacific Investment Management Company and the Transfer Agent to
            act on telephone instructions from any person representing himself
            to be the investor, and reasonably believed by Pacific Investment
            Management Company or the Transfer Agent to be genuine. Neither
            the Trust nor the Transfer Agent may be liable for any loss, cost
            or expense for acting on instructions (whether in writing or by
            telephone) believed by the party receiving such instructions to be
            genuine and in accordance with the procedures described in this
            Prospectus. Shareholders should realize that by electing the
            telephone or wire or e-mail redemption option, they may be giving
            up a measure of security that they might have if they were to
            redeem their shares in writing. Furthermore, interruptions in
            service may mean that a shareholder will be unable to effect a
            redemption by telephone or e-mail when desired. The Transfer Agent
            also provides written confirmation of transactions initiated by
            telephone as a procedure designed to confirm that telephone
            instructions are genuine (written confirmation is also provided
            for redemption requests received in writing or via e-mail). All
            telephone transactions are recorded, and Pacific Investment
            Management Company or the Transfer Agent may request certain
            information in order to verify that the person giving instructions
            is authorized to do so. The Trust or Transfer Agent may be liable
            for any losses due to unauthorized or fraudulent telephone
            transactions if it fails to employ reasonable procedures to
            confirm that instructions communicated by telephone are genuine.
            All redemptions, whether initiated by letter or telephone, will be
            processed in a timely manner, and proceeds will be forwarded by
            wire in accordance with the redemption policies of the Trust
            detailed below. See "Other Redemption Information."

             Shareholders may decline telephone exchange or redemption
            privileges after an account is opened by instructing the Transfer
            Agent in writing at least seven business days prior to the date
            the instruction is to be effective. Shareholders may experience
            delays in exercising telephone redemption privileges during
            periods of abnormal market activity. During periods of volatile
            economic or market conditions, shareholders may wish to consider
            transmitting redemption orders by telegram, facsimile or overnight
            courier.

             Defined contribution plan participants may request redemptions by
            contacting the employee benefits office, the plan administrator or
            the organization that provides recordkeeping services for the
            plan.

              . Other Redemption Information. Redemption requests for Fund
            shares are effected at the NAV per share next determined after
            receipt of a redemption request by the Trust or its designee. The
            request must properly identify all relevant information, such as
            account number, redemption amount (in dollars or shares) and the
            Fund name, and must be executed or initialed by the appropriate
            signatories. A redemption request received by the Trust or its
            designee prior to the close of regular trading on the New York
            Stock Exchange (normally 4:00 p.m., Eastern time), on a day the
            Trust is open for business, is effective on that day. A redemption
            request received after that time becomes effective on the next
            business day.

             Unless eligible for a waiver, shareholders of the Structured
            Emerging Markets and Tax-Efficient Structured Emerging Markets
            Funds who redeem their shares will pay a Fund Reimbursement Fee
            equal to 1.00% of the NAV of the shares redeemed. See "Fund
            Reimbursement Fees" above.

63 PIMCO Funds: Multi-Manager Series
<PAGE>

             Redemption proceeds will ordinarily be wired to the investor's
            bank within three business days after the redemption request, but
            may take up to seven business days. Redemption proceeds will be
            sent by wire only to the bank name designated on the Client
            Registration Application. The Trust may suspend the right of
            redemption or postpone the payment date at times when the New York
            Stock Exchange is closed, or during certain other periods as
            permitted under the federal securities laws.

             For shareholder protection, a request to change information
            contained in an account registration (for example, a request to
            change the bank designated to receive wire redemption proceeds)
            must be received in writing, signed by the minimum number of
            persons designated on the Client Registration Application that are
            required to effect a redemption, and accompanied by a signature
            guarantee from any eligible guarantor institution, as determined
            in accordance with the Trust's procedures. Shareholders should
            inquire as to whether a particular institution is an eligible
            guarantor institution. A signature guarantee cannot be provided by
            a notary public. In addition, corporations, trusts, and other
            institutional organizations are required to furnish evidence of
            the authority of the persons designated on the Client Registration
            Application to effect transactions for the organization.

             Due to the relatively high cost of maintaining small accounts,
            the Trust reserves the right to redeem Institutional Class and
            Administrative Class shares in any account for their then-current
            value (which will be promptly paid to the investor) if at any
            time, due to redemption by the investor, the shares in the account
            do not have a value of at least $100,000. A shareholder will
            receive advance notice of a mandatory redemption and will be given
            at least 30 days to bring the value of its account up to at least
            $100,000. This mandatory redemption policy does not apply to
            participants in PIMCO Advisors Portfolio Strategies, a managed
            product sponsored by PIMCO Advisors.

             The Trust agrees to redeem shares of each Fund solely in cash 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 reserves
            the right to 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 shares would ever
            be redeemed in kind. When shares are redeemed in kind, the
            redeeming shareholder should expect to incur transaction costs
            upon the disposition of the securities received in the
            distribution.

             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.

Exchange
Privilege   Except as provided below, an investor may exchange Institutional
            Class or Administrative Class shares of a Fund for shares of the
            same class of any other Fund or other series of the Trust that
            offers that class based on the respective NAVs of the shares
            involved. An exchange may be made by following the redemption
            procedure described above under "Redemptions by Mail" or, if the
            investor has elected the telephone redemption option, by calling
            the Trust at 1-800-927-4648. An investor may also exchange shares
            of a Fund for shares of the same class of a series of PIMCO Funds:
            Pacific Investment Management Series, an affiliated mutual fund
            family composed primarily of fixed income portfolios managed by
            Pacific Investment Management Company, subject to any restrictions
            on exchanges set forth in the applicable series' prospectus(es).
            Shareholders interested in such an exchange may request a
            prospectus for these other series by contacting PIMCO Funds:
            Pacific Investment Management Series at the same address and
            telephone number as the Trust.

                                                                   Prospectus 64
<PAGE>

             Unless eligible for a waiver, shareholders who exchange their
            Institutional Class or Administrative Class shares of a Fund for
            the same class of shares of the Structured Emerging Markets or
            Tax-Efficient Structured Emerging Markets Fund will be subject to
            a Fund Reimbursement Fee of 1.00% of the NAV of the shares of
            these Funds acquired in connection with the exchange. Also,
            shareholders who exchange shares of the Structured Emerging
            Markets Fund or Tax-Efficient Structured Emerging Markets Fund for
            shares of any other Fund will be subject to a Fund Reimbursement
            Fee of 1.00% of the NAV of the shares of these Funds redeemed in
            connection with the exchange. See "Fund Reimbursement Fees" above.

             An investor may exchange shares only with respect to Funds or
            other eligible series that are registered in the investor's state
            of residence or where an exemption from registration is available.
            In addition, an exchange is generally a taxable event which will
            generate capital gains or losses, and special rules may apply in
            computing tax basis when determining gain or loss. See "Tax
            Consequences" in this Prospectus and "Taxation" in the Statement
            of Additional Information.

             The Trust reserves the right to refuse exchange purchases if, in
            the judgment of PIMCO Advisors, 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 Advisors to be detrimental to the Trust or a
            particular Fund. Currently, the Trust limits the number of "round
            trip" exchanges investors 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 PIMCO 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. The Trust reserves the right
            to impose additional restrictions on exchanges at any time,
            although it will attempt to give shareholders 30 days' prior
            notice whenever it is reasonably able to do so.

            How Fund Shares Are Priced

             The net asset value ("NAV") of a Fund's Institutional and
            Administrative Class 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 the 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 quotes are not readily
            available may be valued, pursuant to procedures established by the
            Board of Trustees, with reference to other securities or 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. In particular, calculation of the NAV
            of the Global Innovation, Allianz Select International, Structured
            Emerging Markets, Tax-Efficient Structured Emerging Markets and
            International Funds may not take place contemporaneously with the
            determination of the prices of foreign securities used in NAV
            calculations.

65  PIMCO Funds: Multi-Manager Series
<PAGE>

             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 their 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 or persons acting at their direction pursuant to
            procedures approved by the Board of Trustees. Fair valuation may
            also be used by the Board of Trustees if extraordinary events
            occur after the close of the relevant market but prior to the NYSE
            Close.

             Under certain circumstances, the per share NAV of the
            Administrative Class shares of the Funds may be lower than the per
            share NAV of the Institutional Class shares as a result of the
            daily expense accruals of the service and/or distribution fees
            paid by Administrative Class 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 the two classes.

            Fund Distributions

            Each Fund distributes substantially all of its net investment
            income to shareholders in the form of dividends. A shareholder
            begins earning dividends on Fund shares the day after the Trust
            receives the shareholder's 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, but dividends on
            Administrative Class shares are expected to be lower than
            dividends on Institutional Class shares as a result of the service
            and/or distribution fees applicable to Administrative Class
            shares. 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.

             A Fund's dividend and capital gain distributions with respect to
            a particular class of shares will automatically be reinvested in
            additional shares of the same class of the Fund at NAV unless the
            shareholder elects to have the distributions paid in cash. A
            shareholder may elect to have distributions paid in cash on the
            Client Registration Application or by submitting a written
            request, signed by the appropriate signatories, indicating the
            account number, Fund name(s) and wiring instructions.

             Shareholders do not pay any sales charges or other fees
            (including Fund Reimbursement Fees) on the receipt of shares
            received through the reinvestment of Fund distributions. However,
            shareholders of the Structured Emerging Markets and Tax-Efficient
            Structured Emerging Markets Funds who receive additional shares
            through the reinvestment of distributions will pay a Fund
            Reimbursement Fee if they subsequently redeem or exchange those
            shares. See "Purchases, Redemptions and Exchanges--Fund
            Reimbursement Fees."

            Tax Consequences

              . Taxes on Fund Distributions. A shareholder subject to U.S.
            federal income tax will be subject to tax on Fund distributions
            whether they are paid in cash or reinvested in additional shares
            of the Funds. For federal income tax purposes, Fund distributions
            will be taxable to the shareholder as either ordinary income or
            capital gains.

             Fund dividends (i.e., distributions of investment income) are
            taxable to shareholders 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 the
            shareholder owned the shares. Distributions of gains from
            investments that a Fund owned for more than 12 months will
            generally be taxable to shareholders as capital gains.
            Distributions of gains from investments that the Fund owned for 12
            months or less will generally be taxable as ordinary income.

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

              . Taxes on Redemptions or Exchanges of Shares. Any gain
            resulting from the sale of Fund shares will generally be subject
            to federal income tax. When a shareholder exchanges shares of a
            Fund for shares of another series, the transaction generally 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.

              . A Note on the Tax-Efficient Equity and Tax-Efficient
            Structured Emerging Markets Funds. The Tax-Efficient Equity and
            Tax-Efficient Structured Emerging Markets Funds utilize a number
            of tax-efficient management techniques designed to minimize
            taxable distributions. For instance, the Funds generally seek to
            minimize realized gains and, when realizing gains, attempt to
            realize gains that will be taxed as capital gains (i.e., as gains
            on investments owned for more than 12 months) when distributed to
            shareholders. Although the Funds attempt to minimize taxable
            distributions, they may be expected to earn and distribute taxable
            income and realize and distribute capital gains from time to time.

              . A Note on Foreign Investments. A Fund's investment in foreign
            securities may be subject to foreign withholding taxes. In that
            case, the Fund's yield on those securities would be decreased. In
            addition, a Fund's investments in foreign securities or foreign
            currencies may increase or accelerate the Fund's recognition of
            ordinary income and may affect the timing or amount of the Fund's
            distributions. Shareholders of the Global Innovation, Allianz
            Select International, Structured Emerging Markets, Tax-Efficient
            Structured Emerging Markets and International Funds may be
            entitled to claim a credit or deduction with respect to foreign
            taxes.

             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
            local income tax laws to Fund dividends and capital distributions.
            Please see the Statement of Additional Information for additional
            information regarding the tax aspects of investing in the Funds.

            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 identified
            under "Summary Information" above. It also describes
            characteristics and risks of additional securities and investment
            techniques that are not necessarily principal investments or
            strategies but may be used by the Funds from time to time. Most of
            these securities and investment techniques are discretionary,
            which means that the portfolio managers 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 must rely on the professional investment judgment and skill
            of PIMCO Advisors, the Sub-Advisers 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.

Fixed       Fixed income securities are obligations of the issuer to make
Income      payments of principal and/or interest on future dates, and include
Securities  corporate and government bonds, notes, certificates of deposit,
and         commercial paper, convertible securities and mortgage-backed and
Defensive   other asset-backed securities.
Strategies

             Aside from the cash management practices described below, the
            Mega-Cap, Capital Appreciation, Mid-Cap, Micro-Cap, Enhanced
            Equity and Tax-Efficient Equity Funds intend to be as fully
            invested in common stocks as practicable at all times. The
            Structured Emerging Markets and Tax-Efficient Structured Emerging
            Markets Funds normally invest substantially all of their assets in
            common stocks and other equity and equity-linked securities, but
            may invest up to 5% of their assets in fixed income securities of
            emerging market issuers. For cash management purposes, each of
            these Funds may maintain a portion of its assets (normally not
            more than 10%) in U.S. Government securities, high quality fixed
            income securities, money market obligations and cash to pay
            certain Fund expenses and to meet redemption requests. None of the
            Funds listed in this paragraph will make defensive investments in
            response to unfavorable market and other conditions and therefore
            may be particularly vulnerable to general declines in stock prices
            and/or other categories of securities in which they invest.

             Under normal circumstances, the Small-Cap Value Fund intends to
            be fully invested in common stocks (aside from cash management
            practices), except that the Fund may temporarily hold up to 10% of
            its assets in cash and cash equivalents for defensive purposes in
            response to unfavorable market and other conditions. The Equity
            Income, Value, Renaissance, Growth, Select Growth, Target,
            Opportunity, Innovation, Global Innovation, Allianz Select
            International and International Funds will each invest primarily
            in common stocks, and may also invest in other kinds of equity
            securities, including preferred stocks and securities (including
            fixed income securities and warrants) convertible into or
            exercisable for common stocks. Each of these Funds may invest a
            portion of its assets in fixed income securities. These Funds may
            temporarily hold up to 100% of their assets in short-term U.S.
            Government securities and other money market instruments for
            defensive purposes in response to unfavorable market and other
            conditions. The Growth & Income Fund will invest primarily in
            common stocks, but may also invest significant portions of its
            assets in preferred stocks, fixed income securities, convertible
            securities and real estate investment trusts, or "REITs." The
            Growth & Income Fund may temporarily hold up to 100% of its assets
            in short-term U.S. Government securities and other money market
            instruments for defensive purposes in response to unfavorable
            market and other conditions. The Allianz Select International and
            International Funds may also hold up to 100% of their assets in
            other domestic fixed income, foreign fixed income and equity
            securities principally traded in the U.S., including obligations
            issued or guaranteed by a foreign government or its agencies,
            authorities or instrumentalities, corporate bonds and

                                                                   Prospectus 68
<PAGE>

            American Depository Receipts, for temporary defensive purposes.
            The temporary defensive strategies described in this paragraph
            would be inconsistent with the investment objective and principal
            investment strategies of each of the noted Funds and may adversely
            affect the Fund's ability to achieve its investment objective.

Companies
With
Smaller
Market
Capitalizations

            Each of the Funds may invest in securities of companies with
            market capitalizations that are small compared to other publicly
            traded companies. The Micro-Cap Fund, in particular, and the
            Opportunity and Small-Cap Value Funds generally invest primarily
            in smaller companies and are especially sensitive to the risks
            described below. In addition, the Innovation and Global Innovation
            Funds generally have substantial exposure to these risks. The
            Target, Growth & Income, Allianz Select International and Mid-Cap
            Funds also have significant exposure to these risks because they
            invest primarily in companies with medium-sized market
            capitalizations, which are smaller and generally less well-known
            or seasoned than the largest companies.

             Companies which are smaller and less well-known or seasoned than
            larger, more widely held companies may offer greater opportunities
            for capital appreciation, but may also involve risks different
            from, or greater than, risks normally associated with larger
            companies. Larger companies generally have greater financial
            resources, more extensive research and development, manufacturing,
            marketing and service capabilities, and more stability and greater
            depth of management and technical personnel than smaller
            companies. Smaller companies may have limited product lines,
            markets or financial resources or may depend on a small,
            inexperienced management group. Securities of smaller companies
            may trade less frequently and in lesser volume than more widely
            held securities and their values may fluctuate more abruptly or
            erratically than securities of larger companies. They may also
            trade in the over-the-counter market or on a regional exchange, or
            may otherwise have limited liquidity. These securities may
            therefore be more vulnerable to adverse market developments than
            securities of larger companies. Also, there may be less publicly
            available information about smaller companies or less market
            interest in their securities as compared to larger companies, and
            it may take longer for the prices of the securities to reflect the
            full value of a company's earnings potential or assets.

             Because securities of smaller companies may have limited
            liquidity, a Fund may have difficulty establishing or closing out
            its positions in smaller companies at prevailing market prices. As
            a result of owning large positions in this type of security, a
            Fund is subject to the additional risk of possibly having to sell
            portfolio securities at disadvantageous times and prices if
            redemptions require the Fund to liquidate its securities
            positions. For these reasons, it may be prudent for a Fund with a
            relatively large asset size to limit the number of relatively
            small positions it holds in securities having limited liquidity in
            order to minimize its exposure to such risks, to minimize
            transaction costs, and to maximize the benefits of research. As a
            consequence, as a Fund's asset size increases, the Fund may reduce
            its exposure to illiquid smaller capitalization securities, which
            could adversely affect performance.

Initial     The Funds, particularly the Global Innovation Fund, may purchase
Public      securities in initial public offerings (IPOs). These securities
Offerings   are subject to many of the same risks of investing in companies
            with smaller market capitalizations. Securities issued in IPOs
            have no trading history, and information about the companies may
            be available for very limited periods. In addition, the prices of
            securities sold in IPOs may be highly volatile. At any particular
            time or from time to time a Fund may not be able to invest in
            securities issued in IPOs, or invest to the extent desired,
            because, for example, only a small portion (if any) of the
            securities being offered in an IPO may be made available to the
            Fund. In addition, under certain market conditions a relatively
            small number of companies may issue securities in IPOs. Similarly,
            as the number of Funds to which IPO securities are allocated
            increases, the number of securities issued to any one Fund may
            decrease. The investment performance of a Fund during periods when
            it is unable to invest significantly or at all in IPOs may be
            lower than during periods when the Fund is able to do so. In
            addition, as a Fund increases in size, the impact of IPOs on the
            Fund's performance will generally decrease.

<PAGE>

Foreign
(non-       The Allianz Select International, Structured Emerging Markets,
U.S.)       Tax-Efficient Structured Emerging Markets and International Funds
Securities  normally invest principally in securities of foreign issuers,
            securities traded principally in securities markets outside the
            United States and/or securities denominated in foreign currencies
            (together, "foreign securities"). The Global Innovation Fund will
            invest in the securities of issuers located in at least three
            countries (one of which may be the United States). The Equity
            Income, Value, Renaissance, Growth & Income, Growth, Target,
            Opportunity and Innovation Funds may invest up to 15% of their
            respective assets in foreign securities. The Select Growth Fund
            may invest up to 25% of its assets in foreign securities. Each of
            these Funds may invest without limit in ADRs (defined below). The
            Enhanced Equity and Tax-Efficient Equity Funds may invest in
            common stocks of foreign issuers if included in the S&P 500 Index.

             All of the Funds may invest in American Depository Receipts
            (ADRs). In addition, the Equity Income, Value, Renaissance, Growth
            & Income, Growth, Select Growth, Target, Opportunity, Innovation,
            Global Innovation, Allianz Select International, Structured
            Emerging Markets, Tax-Efficient Structured Emerging Markets and
            International Funds may invest in European Depository Receipts
            (EDRs) and Global Depository Receipts (GDRs). ADRs are dollar-
            denominated receipts issued generally by domestic banks and
            representing the deposit with the bank of a security of a foreign
            issuer, and are publicly traded on exchanges or over-the-counter
            in the United States. EDRs are receipts similar to ADRs and are
            issued and traded in Europe. GDRs may be offered privately in the
            United States and also traded in public or private markets in
            other countries.

             Investing in foreign securities involves special risks and
            considerations not typically associated with investing in U.S.
            securities and shareholders should consider carefully the
            substantial risks involved for Funds that invest in these
            securities. 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, rate
            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.

Emerging
Market      Each of the Funds that may invest in foreign securities may invest
Securities  in securities of issuers based in or that trade principally in
            countries with developing (or "emerging market") economies. The
            Structured Emerging Markets and Tax-Efficient Structured Emerging
            Markets Funds normally invest most of their assets in emerging
            market securities. The Global Innovation, Allianz Select
            International and International Funds may also invest significant
            portions of their assets in emerging market 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; and possible repatriation of investment
            income and capital. In addition, foreign investors may be required
            to register the proceeds of sales, and future economic or
            political crises could lead to price controls, forced mergers,
            expropriation or confiscatory taxation, seizure, nationalization
            or the creation of government monopolies. The currencies of
            emerging market countries may experience significant declines
            against the U.S. dollar, and devaluation may

                                                                   Prospectus 70

            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 market 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.

             Special Risks of Investing in Russian and Other Eastern European
            Securities. Each of the Global Innovation, Allianz Select
            International, Structured Emerging Markets, Tax-Efficient
            Structured Emerging Markets and International Funds may invest a
            significant portion of its assets in securities of issuers located
            in Russia and in other Eastern European countries. While
            investments in securities of such issuers are subject generally to
            the same risks associated with investments in other emerging
            market countries described above, the political, legal and
            operational risks of investing in Russian and other Eastern
            European issuers, and of having assets custodied within these
            countries, may be particularly acute. A risk of particular note
            with respect to direct investment in Russian securities is the way
            in which ownership of shares of companies is normally recorded.
            When a Fund invests in a Russian issuer, it will normally receive
            a "share extract," but that extract is not legally determinative
            of ownership. The official record of ownership of a company's
            share is maintained by the company's share registrar. Such share
            registrars are completely under the control of the issuer, and
            investors are provided with few legal rights against such
            registrars.

Foreign
Currencies  A Fund that invests directly in foreign currencies or in
            securities that trade in, and receive revenues in, foreign
            currencies will be subject to currency risk. The Global
            Innovation, Allianz Select International, Structured
            Emerging Markets, Tax-Efficient Structured Emerging Markets and
            International Funds are particularly sensitive to this risk.

             Foreign currency exchange rates may fluctuate significantly over
            short periods of time. They generally are determined by supply and
            demand 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, uncertainty
            surrounds the introduction of the euro (a common currency unit for
            the European Union) and the effect it may have on the value of
            European currencies as well as securities denominated in local
            European currencies. The euro 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. The Equity Income, Value,
            Renaissance, Growth & Income, Growth, Select Growth, Target,
            Opportunity, Innovation, Global Innovation, Allianz Select
            International, Structured Emerging Markets, Tax-Efficient
            Structured Emerging Markets and International Funds may enter into
            forward foreign currency exchange contracts, primarily to reduce
            the risks of adverse changes in foreign exchange rates. In
            addition, the Global Innovation, Allianz Select International,
            Structured Emerging Markets, Tax-Efficient Structured Emerging
            Markets and International Funds may buy and sell foreign currency
            futures contracts and options on foreign currencies and foreign
            currency futures. A forward foreign currency exchange contract,

71 PIMCO Funds: Multi-Manager Series
<PAGE>

            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. Contracts to sell foreign
            currency would limit any potential gain which might be realized by
            a Fund if the value of the hedged currency increases. A Fund may
            enter into these contracts to hedge against foreign exchange risk
            arising from the Fund's investment or anticipated investment in
            securities denominated in foreign currencies. 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.

             The Global Innovation, Allianz Select International, Structured
            Emerging Markets, Tax-Efficient Structured Emerging Markets and
            International Funds may also enter into these contracts for
            purposes of increasing exposure to a foreign currency or to shift
            exposure to foreign currency fluctuations from one currency to
            another. To the extent that it does so, a Fund will be subject to
            the additional risk that the relative value of currencies will be
            different than anticipated by the Fund's portfolio manager. The
            Global Innovation, Allianz Select International, Structured
            Emerging Markets, Tax-Efficient Structured Emerging Markets and
            International Funds may use one currency (or basket of currencies)
            to hedge against adverse changes in the value of another currency
            (or basket of currencies) when exchange rates between the two
            currencies are positively correlated. Each Fund will segregate
            assets determined to be liquid by PIMCO Advisors or a Sub-Adviser
            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.

Corporate   Each Fund that may invest in fixed income securities may invest in
Debt        corporate debt securities. The Growth & Income Fund may invest up
Securities  to 10% of its assets in these securities. Corporate debt
            securities are subject to the risk of the issuer's inability to
            meet principal and interest payments on the obligation and may
            also be subject to price volatility due to factors such 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 durations tend to
            be more sensitive to interest rate movements than those with
            shorter durations.

Convertible Each Fund may invest in convertible securities. The Growth &
Securities  Income Fund may place particular emphasis on convertible
            securities. Convertible securities are generally preferred stocks
            and other securities, including fixed income securities and
            warrants, that are convertible into or exercisable for common
            stock at either a stated price or a stated 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. While
            convertible securities generally offer lower interest or dividend
            yields than non-convertible fixed income securities of similar
            quality, their value tends to increase as the market value of the
            underlying stock increases and to decrease when the value of the
            underlying stock decreases. Also, 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.

Derivatives
            Each Fund (except the Mega-Cap, Capital Appreciation, Mid-Cap,
            Micro-Cap and Small-Cap Value Funds) may, but is not required to,
            use a number of 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. 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

                                                                   Prospectus 72
<PAGE>


            succeed. In addition, 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.

             Examples of derivative instruments include options contracts,
            futures contracts, options on futures contracts and swap
            agreements. The Equity Income, Value, Renaissance, Growth &
            Income, Growth, Select Growth, Target, Opportunity, Innovation,
            Global Innovation, Allianz Select International, Tax-Efficient
            Equity, Structured Emerging Markets, Tax-Efficient Structured
            Emerging Markets and International Funds may purchase and sell
            (write) call and put options on securities, securities indexes and
            foreign currencies. Each of these Funds may purchase and sell
            futures contracts and options thereon with respect to securities,
            securities indexes and foreign currencies. The Enhanced Equity
            Fund may purchase and write options on securities indexes and
            enter into securities index futures contracts and options on
            securities index futures contracts. The Global Innovation, Allianz
            Select International, Tax-Efficient Equity, Structured Emerging
            Markets and Tax-Efficient Structured Emerging Markets may enter
            into swap agreements with respect to securities indexes. 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 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.

             Leveraging 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 Advisors or a Sub-Adviser
            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 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
            (taxed at ordinary income tax rates when distributed to
            shareholders who are individuals) than if the Fund had not used
            such instruments.

Equity-
Linked      The Funds may invest in equity-linked securities. Each of the
Securities  Allianz Select International, Structured Emerging Markets and Tax-
            Efficient Structured Emerging Markets Funds may invest up to 15%
            of its assets in equity-linked securities. The International Fund
            may invest up to 5% of its assets in equity-linked securities.
            Equity-linked securities are privately issued securities whose
            investment results are designed to correspond generally to the
            performance of a specified stock index or "basket" of stocks, or
            sometimes a single stock. To the extent that a Fund invests in
            equity-linked securities whose return corresponds to the
            performance of a foreign securities index or one or more of
            foreign stocks, investing in equity-linked securities will involve
            risks similar to the risks of investing in foreign equity
            securities. See "Foreign Securities" above. In addition, an
            investing Fund bears the risk that the issuer of an equity-linked
            security may default on its obligations under the security.
            Equity-linked securities may be considered illiquid and thus
            subject to the Funds' restrictions on investments in illiquid
            securities.

            The Funds may invest in securities based on their credit ratings
Credit      assigned by rating agencies such as Moody's Investors Service,
Ratings     Inc. ("Moody's") and Standard & Poor's Ratings Services ("S&P").
and         Moody's, S&P and other rating agencies are private services that
Unrated     provide ratings of the credit quality of fixed income securities,
Securities  including convertible securities. The Appendix to the Statement of
            Additional Information 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 risk. 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 Advisors and the
            Sub-Advisers do not rely solely on credit ratings, and develop
            their 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.


High
Yield
Securities  Securities rated lower than Baa by Moody's or lower than BBB by
            S&P are sometimes referred to as "high yield securities" or "junk
            bonds." The Funds, particularly the Growth & Income Fund, may
            invest in these securities. Investing in these securities involves
            special risks in addition to the risks associated with investments
            in higher-rated

                                                                   Prospectus 74
<PAGE>


            fixed income securities. While offering a greater potential
            opportunity for capital appreciation and higher yields, these
            securities typically may be subject to greater levels of interest
            rate, credit and liquidity risk and may entail greater potential
            price volatility and may be less liquid than higher-rated
            securities. These 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.

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 the party arranging the loan.

Short       Each Fund may make short sales as part of its overall portfolio
Sales       management strategies or to offset a potential decline in the
            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. A Fund may only enter into short selling transactions if
            the security sold short is held in the Fund's portfolio or if the
            Fund has the right to acquire the security without the payment of
            further consideration. 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.

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
Transactionssettlement date. This risk is in addition to the risk that the
            Fund's other assets will decline in 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 that 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. Those Funds whose investment objectives do not
            include the earning of income will invest in repurchase agreements
            only as a cash management technique with respect to that portion
            of its portfolio maintained in cash. Repurchase agreements
            maturing in more than seven days are considered illiquid
            securities.

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

            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 and other forms of borrowings may create leveraging
            risk for a Fund.

Illiquid    Each Fund may invest in securities that are illiquid so long as
Securities  not more than 15% of the value of the Fund's net assets (taken at
            market value at the time of investment) would be invested in such
            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 held by the
            Fund, 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. Please see "Investment Objectives and Policies" in
            the Statement of Additional Information for a listing of various
            securities that are generally considered to be illiquid for these
            purposes. 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
in Other    The Allianz Select International and International Funds may
Investment  invest up to 10% of their assets in securities of other investment
Companies   companies, such as closed-end management investment companies, or
            in pooled accounts or other investment vehicles which invest in
            foreign markets. Each of the other Funds may invest up to 5% of
            its assets in other investment companies. 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.

Portfolio
Turnover    With the exception of the Tax-Efficient Equity and Tax-Efficient
            Structured Emerging Markets Funds, the length of time a Fund has
            held a particular security is not 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 active and
            frequent trading of portfolio securities to achieve its investment
            objective and principal investment strategies, particularly during
            periods of volatile market movements, although the Tax-Efficient
            Equity and Tax-Efficient Structured Emerging Markets Funds will
            generally attempt to limit portfolio turnover as part of their
            tax-efficient management strategies. 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 taxed at ordinary income tax rates when distributed to
            shareholders who are individuals). The trading costs and tax
            effects associated with portfolio turnover may adversely affect a
            Fund's performance. Funds, such as the Growth & Income, Select
            Growth and Allianz Select International Funds, that have recently
            changed Sub-Advisers and/or investment objectives and policies may
            experience increased portfolio turnover due to the differences
            between the Funds' previous and current investment objectives and
            policies and portfolio management strategies.

Changes     The investment objective of each of the Renaissance, Growth &
in          Income, Growth, Select Growth, Target, Opportunity, Innovation,
Investment  Global Innovation, Allianz Select International, Mega-Cap, Tax-
Objectives  Efficient Equity, Tax-Efficient Structured Emerging Markets and
and         International Funds described in this Prospectus may be changed by
Policies    the Board of Trustees without shareholder approval. The investment
            objective of each other Fund is fundamental and may not be changed
            without shareholder approval. Unless otherwise stated in the
            Statement of Additional Information, all investment policies of
            the Funds may be changed by the Board of Trustees without
            shareholder approval. If there is a change in a Fund's investment
            objective or policies, including a change approved by shareholder
            vote, shareholders should consider whether the Fund remains an
            appropriate investment in light of their then current financial
            position and needs.


                                                                   Prospectus 76

New and
Smaller-    In addition to the risks described under "Summary of Principal
Sized       Risks" above and in this section, several of the Funds are newly
Funds       formed and therefore have limited or no performance history for
            investors to evaluate. Also, it is possible that newer Funds and
            smaller-sized Funds may invest in securities offered in initial
            public offerings and other types of transactions (such as private
            placements) which, because of the Funds' size, may have a
            disproportionate impact on the Funds' performance results. The
            Funds would not necessarily have achieved the same performance
            results if their aggregate net assets had been greater.

Percentage  Unless otherwise stated, all percentage limitations on Fund
Investment  investments listed in this Prospectus will apply at the time of
Limitations investment. A Fund would not violate these limitations unless an
            excess or deficiency occurs or exists immediately after and as a
            result of an investment.

Other       The Funds may invest in other types of securities and use a
Investments variety of investment techniques and strategies which are not
and         described in this Prospectus. These securities and techniques may
Techniques  subject the Funds to additional risks. Please see the Statement of
            Additional Information for additional information about the
            securities and investment techniques described in this Prospectus
            and about additional securities and techniques that may be used by
            the Funds.

            Financial Highlights

            The financial highlights table is intended to help a shareholder
            understand the financial performance of Institutional and
            Administrative Class shares of each Fund for the past 5 years or,
            if the class is less than 5 years old, since the class of shares
            was first offered. Certain information reflects financial results
            for a single Fund share. The total returns in the table represent
            the rate that an investor would have earned or lost on an
            investment in a particular class of shares of a Fund, assuming
            reinvestment of all dividends and distributions. This information
            has been audited by PricewaterhouseCoopers LLP, whose report,
            along with each Fund's financial statements, are included in the
            Trust's annual report to shareholders. The annual report is
            incorporated by reference in the Statement of Additional
            Information and is available free of charge upon request from the
            Distributor.

(iii) Formerly the PIMCO Core Equity Fund. The Fund changed its investment
      objective and policies on April 1, 2000; the performance results shown
      above would not necessarily have been achieved had the Fund's current
      objective and policies been in effect during the periods shown. In
      addition, the performance results shown above reflect the Fund's
      advisory fee level in effect prior to April 1, 2000; these results would

            Summary Information (continued)

Fund        The Funds provide a broad range of investment choices. The
Descrip-    following Fund Summaries identify each Fund's investment
tions,      objective, principal investments and strategies, principal risks,
Performance performance information and fees and expenses. A more detailed
and Fees    "Summary of 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. The fact
            that a fund had good performance in the past (for example, during
            the year ended 1999) is no assurance that the value of the Fund's
            investments will not decline in the future or appreciate at a
            slower rate. 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.

                                                                   Prospectus  4

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of companies
            with larger market capitalizations that have improving
            fundamentals (based on growth criteria) and whose stock is
            reasonably valued by the market (based on value criteria).

             In making investment decisions for the Fund, the portfolio
            management team considers the 1,000 largest publicly traded
            companies (in terms of market capitalization) in the U.S. The team
            screens the stocks in this universe for a series of growth
            criteria, such as dividend growth, earnings growth, relative
            growth of earnings over time (earnings momentum) and the company's
            history of meeting earnings targets (earnings surprise), and also
            value criteria, such as price-to-earnings, price-to-book and
            price-to-cash flow ratios. The team then selects individual stocks
            by subjecting the top 10% of the stocks in the screened universe
            to a rigorous analysis of company factors, such as strength of
            management, competitive industry position, and business prospects,
            and financial statement data, such as earnings, cash flows and
            profitability. The team may interview company management in making
            investment decisions. The Fund's capitalization criteria applies
            at the time of investment.

             The portfolio management team rescreens the universe frequently
            and seeks to consistently achieve a favorable balance of growth
            and value characteristics for the Fund. The team looks to sell a
            stock when it falls below the median ranking, has negative
            earnings surprises, or shows poor price performance relative to
            all stocks in the Fund's capitalization range or to companies in
            the same business sector. A stock may also be sold if its
            weighting in the portfolio becomes excessive (normally above 2% of
            the Fund's investments).

             The Fund intends to be fully invested in common stock (aside from
            certain cash management practices) and will not make defensive
            investments in response to unfavorable market and other
            conditions.

            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 and the information to its
            right show performance of the Fund's Class A shares, but the
            returns do not reflect the impact of sales charges (loads). If
            they did, the returns would be lower than those shown. Unlike the
            bar chart, performance for Class A, B and C shares in the Average
            Annual Total Returns table reflects the impact of sales charges.
            For periods prior to the inception of Class A, B and C shares
            (1/20/97), performance information shown in the bar chart and
            tables for those classes is based on the performance of the Fund's
            Institutional Class shares, which are offered in a different
            prospectus. The prior Institutional Class performance has been
            adjusted to reflect the actual sales charges (in the Average
            Annual Total Returns table only), distribution and/or service
            (12b-1) fees, administrative fees and other expenses paid by Class
            A, B and C shares. Past performance is no guarantee of future
            results.

                net assets attributable in the aggregate to the Fund's Class A,
                B and C shares in excess of $2.5 billion, and 0.01% in other
                expenses attributable to that class during the most recent
                fiscal year.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class A, B or C 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 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.

</TABLE>

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in income-producing (e.g.,
            dividend-paying) common stocks of companies with market
            capitalizations of more than $2 billion at the time of investment.
            The Fund may also invest to a limited degree in convertible
            securities and preferred stocks.

             The Fund's initial selection universe consists of the 1,000
            largest publicly traded companies (in terms of market
            capitalization) in the U.S. The portfolio managers classify the
            universe by industry. They then identify the most undervalued
            stocks in each industry based mainly on relative P/E ratios,
            calculated both with respect to trailing operating earnings and
            forward earnings estimates. From this group of stocks, the Fund
            buys approximately 25 stocks with the highest dividend yields. The
            portfolio managers then screen the most undervalued companies in
            each industry by dividend yield to identify the highest yielding
            stocks in each industry. From this group, the Fund buys
            approximately 25 additional stocks with the lowest P/E ratios.

             In selecting stocks, the portfolio managers consider quantitative
            factors such as price momentum (based on changes in stock price
            relative to changes in overall market prices), earnings momentum
            (based on analysts' earnings per share estimates and revisions to
            those estimates), relative dividend yields, valuation relative to
            the overall market and trading liquidity. The portfolio managers
            may replace a stock when a stock within the same industry group
            has a considerably higher dividend yield or lower valuation than
            the Fund's current holding.

             The Fund may invest up to 15% of its assets in foreign
            securities, except that it may invest without limit in American
            Depository Receipts (ADRs). In response to unfavorable market and
            other conditions, the Fund may make temporary investments of some
            or all of its assets in high-quality fixed income securities. This
            would be inconsistent with the Fund's investment objective and
            principal strategies.

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

</TABLE>

            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 and the information to its
            right show performance of the Fund's Class A shares, but the
            returns do not reflect the impact of sales charges (loads). If
            they did, the returns would be lower than those shown. Unlike the
            bar chart, performance for Class A, B and C shares in the Average
            Annual Total Returns table reflects the impact of sales charges.
            For periods prior to the inception of Class A, B and C shares
            (1/20/97), performance information shown in the bar chart and
            tables for those classes is based on the performance of the Fund's
            Institutional Class shares, which are offered in a different
            prospectus. The prior Institutional Class performance has been
            adjusted to reflect the actual sales charges (in the Average
            Annual Total Returns table only), distribution and/or service
            (12b-1) fees, administrative fees and other expenses paid by Class
            A, B and C shares. Prior to May 8, 2000, the Fund had a different
            sub-adviser and would not necessarily have achieved the
            performance results shown on the next page under its current
            investment management arrangements. Past performance is no
            guarantee of future results.

            (1) Due to the 12b-1 distribution fee imposed on Class B and Class
                C shares, Class B or Class C shareholders may, depending upon
                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 National Association of
                Securities Dealers, Inc.

            (2) Other Expenses reflects a 0.40% Administrative Fee paid by the
             class, which is subject to a reduction of 0.05% on average daily
             net assets attributable in the aggregate to the Fund's Class A, B
             and C shares in excess of $2.5 billion, and 0.02% in other
             expenses attributable to that class during the most recent fiscal
             year.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class A, B or C 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 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.

</TABLE>

              The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of U.S. and
            non-U.S. companies which utilize new, creative or different, or
            "innovative," technologies to gain a strategic competitive
            advantage in their industry, as well as companies that provide and
            service those technologies. The Fund identifies its investment
            universe of technology-related companies primarily by reference to
            classifications made by independent firms, such as Standard &
            Poor's (for example, companies classified as "Information
            Technology" companies), and by identifying companies that derive a
            substantial portion of their revenues from the manufacture, sale
            and/or service of technological products. Although the Fund
            emphasizes companies which utilize technologies, it is not
            required to invest exclusively in a particular business sector or
            industry.

              The portfolio manager selects stocks for the Fund using a
            "growth" style. The portfolio manager seeks to identify
            technology-related companies with well-defined "wealth creating"
            characteristics, including superior earnings growth (relative to
            companies in the same industry or the market as a whole), high
            profitability and consistent, predictable earnings. In addition,
            through fundamental research, the portfolio manager seeks to
            identify companies that are gaining market share, have superior
            management and possess a sustainable competitive advantage, such
            as superior or innovative products, personnel and distribution
            systems. The Fund looks to sell a stock when the portfolio manager
            believes that earnings or market sentiment are disappointing, if
            the company does not meet or exceed consensus estimates on
            revenues and/or earnings or if an alternative investment is more
            attractive.

              Although the Fund invests principally in common stocks, the Fund
            may also invest in other types of equity securities, including
            preferred stocks and convertible securities. The Fund may invest a
            substantial portion of its assets in the securities of smaller
            capitalization companies and securities issued in initial public
            offerings (IPOs). The Fund will invest in the securities of
            issuers located in at least three countries (one of which may be
            the United States). Although the Fund invests primarily in
            securities traded principally in the securities markets of
            developed countries, the Fund has no other prescribed limits on
            geographic asset distribution and may invest in any foreign
            securities market in the world, including in developing, or
            "emerging," markets. The Fund may utilize foreign currency
            exchange contracts and derivative instruments (such as stock index
            futures contracts), primarily for risk management or hedging
            purposes.

              In response to unfavorable market and other conditions, the Fund
            may make temporary investments of some or all of its assets in
            high-quality fixed income securities. This would be inconsistent
            with the Fund's investment objective and principal strategies.

            (1) Due to the 12b-1 distribution fee imposed on Class B and Class
                C shares, Class B or Class C shareholders may, depending upon
                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 National Association of
                Securities Dealers, Inc.

            (2) Other Expenses reflects a 0.60% Administrative Fee paid by the
                class, which is subject to a reduction of 0.05% on average daily
                net assets attributable in the aggregate to the Fund's Class A,
                B and C shares in excess of $2.5 billion, and 0.06%, 0.10% and
                0.10% in organizational expenses ("Organizational Expenses")
                attributable to Class A, Class B, and Class C shares,
                respectively, during the most recent fiscal year.

            (3) Net Expenses reflect the effect of a contractual agreement by
                PIMCO Advisors to waive, reduce or reimburse its Administrative
                Fees for each class in an amount that, in essence, is equal to
                the Fund's Organizational Expenses attributed to the class.
                Because the Organizational Expenses were accounted for in the
                Fund's initial fiscal year, the Fund's reasonable expectation is
                that the relevant conditions will not continue after the Fund's
                fiscal year ending June 30, 2000.


            Examples. The Examples are intended to help you compare the cost
            of investing in Class A, B or C 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

              Growth Stocks

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of "growth"
            companies with market capitalizations of at least $5 billion at
            the time of investment.

             The portfolio manager selects stocks for the Fund using a
            "growth" style. The portfolio manager seeks to identify companies
            with well-defined "wealth creating" characteristics, including
            superior earnings growth (relative to companies in the same
            industry or the market as a whole), high profitability and
            consistent, predictable earnings. In addition, through fundamental
            research, the portfolio manager seeks to identify companies that
            are gaining market share, have superior management and possess a
            sustainable competitive advantage, such as superior or innovative
            products, personnel and distribution systems. The Fund looks to
            sell a stock when the portfolio manager believes that its
            earnings, market sentiment or relative performance are
            disappointing or if an alternative investment is more attractive.

             The Fund may also invest to a limited degree in other kinds of
            equity securities, including preferred stocks and convertible
            securities. The Fund may invest up to 15% of its assets in foreign
            securities, except that it may invest without limit in American
            Depository Receipts (ADRs). The Fund has in the past invested a
            significant portion of its assets in technology or technology-
            related companies, although there is no assurance that it will
            continue to do so in the future.

             In response to unfavorable market and other conditions, the Fund
            may make temporary investments of some or all of its assets in
            high-quality fixed income securities. This would be inconsistent
            with the Fund's investment objective and principal strategies.

            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 and the information to its
            right show performance of the Fund's Class C shares, but the
            returns do not reflect the impact of sales charges (loads). If
            they did, the returns would be lower than those shown. Unlike the
            bar chart, performance for Class A, B and C shares in the Average
            Annual Total Returns table reflects the impact of sales charges.
            For periods prior to the inception of Class A shares (10/26/90)
            and Class B shares (5/23/95), performance information shown in the
            Average Annual Total Returns table for those classes is based on
            the performance of the Fund's Class C shares. The prior Class C
            performance has been adjusted to reflect the actual sales charges,
            distribution and/or service (12b-1) fees, administrative fees and
            other expenses paid by Class A and B shares. Prior to March 6,
            1999, the Fund had a different sub-adviser and would not
            necessarily have achieved the performance results shown on the
            next page under its current investment management arrangements.
            Past performance is no guarantee of future results.

                the length of time the shares are held, pay more than the
                economic equivalent of the maximum front-end sales charges

             net assets attributable in the aggregate to the Fund's Class A, B
             and C shares in excess of $2.5 billion, and 0.01% in other
             expenses attributable to that class during the most recent fiscal
             year.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class A, B or C 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 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
              Blend Stocks

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in securities of companies
            with market capitalizations of at least $1 billion at the time of
            investment. The Fund may invest up to 75% of its assets in
            securities selected for their growth potential. The Fund will
            normally invest at least 25% of its assets in securities selected
            for their income potential, including dividend-paying common
            stocks, preferred stocks, corporate bonds, convertible securities
            and real estate investment trusts (REITs).

             When selecting securities for the Fund's "growth" segment, the
            portfolio managers seek to identify companies with well-defined
            "wealth creating" characteristics, including superior earnings
            growth (relative to companies in the same industry or the market
            as a whole), high profitability and consistent, predictable
            earnings. In addition, through fundamental research, the portfolio
            managers seek to identify companies that are gaining market share,
            have superior management and possess a sustainable competitive
            advantage, such as superior or innovative products, personnel and
            distribution systems. The Fund's portfolio managers may choose to
            sell a stock in the "growth" segment when they believe that its
            earnings will be disappointing or that market sentiment on the
            company will turn negative. The portfolio managers will also
            consider selling a stock if the company does not meet the
            managers' estimates on revenues and/or earnings, or if an
            alternative investment is deemed to be more attractive.

             When selecting securities for the Fund's "Income" segment, the
            portfolio managers seek to identify companies with strong
            operating fundamentals that offer potential for capital
            appreciation and that also have a dividend yield in excess of the
            yield on the S&P 500 Index. The portfolio managers may replace an
            "income" security when another security with a similar risk-to-
            reward profile offers either better potential for capital
            appreciation or a higher yield than the Fund's current holding. To
            achieve its income objective, the Fund may also invest to a
            limited degree in preferred stocks, convertible securities and
            REITs. The Fund may invest up to 10% of its assets in corporate
            bonds, which will typically consist of investment grade securities
            of varying maturities but may also include high yield securities
            ("junk bonds") rated at least B by Standard & Poor's Rating
            Services or Moody's Investors Service, Inc. or, if unrated,
            determined by the Adviser to be of comparable quality.

             The Fund may invest up to 15% of its assets in foreign
            securities, except that it may invest without limit in American
            Depository Receipts (ADRs). The Fund has in the past invested a
            significant portion of its assets in technology or technology-
            related companies, although there is no assurance that it will
            continue to do so in the future. In response to unfavorable market
            and other conditions, the Fund may make temporary investments of
            some or all of its assets in high-quality fixed income securities.
            This would be inconsistent with the Fund's investment objective
            and principal strategies.

            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 and the information to its
            right show performance of the Fund's Institutional Class shares,
            which are offered in a different prospectus. This is because the
            Fund did not offer Class A, B or C shares during the periods
            shown. Although Institutional Class and Class A, B and C shares
            would have similar annual returns (because all the Fund's shares
            represent interests in the same portfolio of securities),
            Institutional Class performance would be higher than Class A, B or
            C performance because of the lower expenses and no sales charges
            paid by Institutional Class shares. The Average Annual Total
            Returns table also shows estimated historical performance for
            Class A, B, and C shares based on the performance of the Fund's
            Institutional Class shares, adjusted to reflect the actual sales
            charges (loads), distribution and/or service (12b-1) fees,
            administrative fees and other expenses paid by Class A, B and C
            shares. The performance information on the next page for periods
            prior to August 1, 2000 reflects the Fund's advisory fee rate in
            effect prior to that date (0.63% per annum), which is higher than
            the current rate (0.60% per annum). Prior to July 1, 1999, the
            Fund had a different sub-adviser and would not necessarily have
            achieved the performance results shown on the next page under its
            current investment management arrangements. In addition, the Fund
            changed its investment objective and policies on August 1, 2000;
            the performance results shown on the next page would not
            necessarily have been achieved had the Fund's current objective
            and policies then been in effect. Past performance is no guarantee
            of future results.

            (1) The S&P Mid-Cap 400 Index is an unmanaged index of middle
                capitalization U.S. stocks. It is not possible to invest
                directly in the index.

            (2) The Lipper Large-Cap Core Funds Average is a total return
                performance average of funds tracked by Lipper Analytical
                Services, Inc. that invest primarily in companies with market
                capitalizations of greater than 300% of the dollar-weighted
                median market capitalization of the S&P Mid-Cap 400 Index. It
                does not take into account sales charges. The Lipper Large-Cap
                Core Funds Average replaced the Lipper Mid-Cap Fund Average (a
                total return performance average of funds tracked by Lipper

                with market capitalizations of less than $5 billion at the
                time of investment) because PIMCO Advisors believes the Large-
                Cap Core Funds Average is more representative of the Fund's
                investment strategies. For periods ended December 31, 1999,
                the 1 Year, 5 Years and Fund Inception average annual total
                returns of the Lipper Mid-Cap Fund Average were 39.38%, 23.07%
                and 23.07%, respectively.

            (2) Due to the 12b-1 distribution fee imposed on Class B and Class
                C shares, Class B or Class C shareholders may, depending upon
                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 National Association of
                Securities Dealers, Inc.

             class, which is subject to a reduction of 0.05% on average daily
             net assets attributable in the aggregate to the Fund's Class A, B
             and C shares in excess of $2.5 billion, and 0.15% in other
             expenses estimated to be attributable to the class during the
             current fiscal year.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class A, B or C 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 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.

              Stocks


            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of companies
            which utilize new, creative or different, or "innovative,"
            technologies to gain a strategic competitive advantage in their
            industry, as well as companies that provide and service those
            technologies. The Fund identifies its investment universe of
            technology-related companies primarily by reference to
            classifications made by independent firms, such as Standard &
            Poor's (for example, companies classified as "Information
            Technology" companies), and by identifying companies that derive a
            substantial portion of their revenues from the manufacture, sale
            and/or service of technological products. Although the Fund
            emphasizes companies which utilize technologies, it is not
            required to invest exclusively in companies in a particular
            business sector or industry.

             The portfolio manager selects stocks for the Fund using a
            "growth" style. The portfolio manager seeks to identify
            technology-related companies with well-defined "wealth creating"
            characteristics, including superior earnings growth (relative to
            companies in the same industry or the market as a whole), high
            profitability and consistent, predictable earnings. In addition,
            through fundamental research, the portfolio manager seeks to
            identify companies that are gaining market share, have superior
            management and possess a sustainable competitive advantage, such
            as superior or innovative products, personnel and distribution
            systems. The Fund looks to sell a stock when the portfolio manager
            believes that earnings or market sentiment are disappointing, if
            the company does not meet or exceed consensus estimates on
            revenues and/or earnings or if an alternative investment is more
            attractive.

             Although the Fund invests principally in common stocks, the Fund
            may also invest in other kinds of equity securities, including
            preferred stocks and convertible securities. The Fund may invest a
            substantial portion of its assets in the securities of smaller
            capitalization companies. The Fund may invest up to 15% of its
            assets in foreign securities, except that it may invest without
            limit in American Depository Receipts (ADRs). In response to
            unfavorable market and other conditions, the Fund may make
            temporary investments of some or all of its assets in high-quality
            fixed income securities. This would be inconsistent with the
            Fund's investment objective and principal strategies.

            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 and the information to its
            right show performance of the Fund's Class A shares, but the
            returns do not reflect the impact of sales charges (loads). If
            they did, the returns would be lower than those shown. Unlike the
            bar chart, performance for Class A, B and C shares in the Average
            Annual Total Returns table reflects the impact of sales charges.
            For periods prior to the inception of Class B shares (5/22/95),
            performance information shown in the Average Annual Total Returns
            table for that class is based on the performance of the Fund's
            Class A shares. The prior Class A performance has been adjusted to
            reflect the actual sales charges, distribution and/or service
            (12b-1) fees, administrative fees and other expenses paid by Class
            B shares. Prior to March 6, 1999, the Fund had a different sub-
            adviser and would not necessarily have achieved the performance
            results shown on the next page under its current investment
            management arrangements. Past performance is no guarantee of
            future results.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class A, B or C 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 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.

              Category
              International
              Stocks

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in an international portfolio
            of common stocks, which may or may not pay dividends. The Fund
            normally invests in securities traded principally in developed
            foreign securities markets, but may also invest up to 30% of its
            assets in developing or "emerging" markets. The Fund has no
            prescribed limits on geographic asset distribution and may invest
            in any foreign securities market in the world. The Fund may also
            invest in securities of foreign issuers traded on U.S. securities
            markets, but will normally not invest in U.S. issuers. The Fund
            invests most of its assets in foreign securities which trade in
            currencies other than the U.S. dollar and may invest directly in
            foreign currencies.

             The portfolio manager uses a "top down" investment approach. He
            first determines regional and country weightings for the Fund by
            considering such factors as the condition and growth potential of
            the various economies and securities markets, currency and
            taxation considerations and other financial, social, national and
            political factors. The Sub-Adviser's country specialists then
            select individual stocks to fill out the desired country
            weightings. In selecting stocks, the specialists analyze a broad
            range of company fundamentals, such as price-to-earnings, price-
            to-book value and price-to-cash flow ratios (value factors),
            earnings, dividend and profit growth (growth factors) and balance
            sheet strength and return on assets (quality factors). The
            portfolio manager sells stocks in order to adjust or rebalance the
            Fund's regional and country weightings or to replace companies
            with weakening fundamentals.

             The Fund may utilize foreign currency exchange contracts and
            derivative instruments (such as stock index futures contracts)
            primarily for risk management or hedging purposes. The Fund may
            also invest in equity securities other than common stocks (such as
            preferred stocks and convertible securities) and may invest up to
            10% of its assets in other investment companies. In response to
            unfavorable market and other conditions, the Fund may make
            temporary investments of some or all of its assets in foreign and
            domestic fixed income securities and in equity securities of U.S.
            issuers. This would be inconsistent with the Fund's investment
            objective and principal strategies.

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 and the information to its
            right show performance of the Fund's Class C shares, but the
            returns do not reflect the impact of sales charges (loads). If
            they did, the returns would be lower than those shown. Unlike the
            bar chart, performance for Class A, B and C shares in the Average
            Annual Total Returns table reflects the impact of sales charges.
            For periods prior to the inception of Class A shares (2/1/91) and
            Class B shares (5/22/95), performance information shown in the
            Average Annual Total Returns table for those classes is based on
            the performance of the Fund's Class C shares. The prior Class C
            performance has been adjusted to reflect the actual sales charges,

                net assets attributable in the aggregate to the Fund's Class A,
                B and C shares in excess of $2.5 billion, and 0.07% in other
                expenses attributable to Class A shares during the most recent

                and Class C shares during the most recent fiscal year.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class A, B or C 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 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 at least 65% of its assets in common stocks of companies
            with medium market capitalizations that have improving
            fundamentals (based on growth criteria) and whose stock is
            reasonably valued by the market (based on value criteria).

             In making investment decisions for the Fund, the portfolio
            management team considers companies in the U.S. market with market
            capitalizations of more than $500 million, but excluding the 200
            largest capitalization companies. The team screens the stocks in
            this universe for a series of growth criteria, such as dividend
            growth, earnings growth, relative growth of earnings over time
            (earnings momentum) and the company's history of meeting earnings
            targets (earnings surprise), and also value criteria, such as
            price-to-earnings, price-to-book and price-to-cash flow ratios.
            The team then selects individual stocks by subjecting the top 10%
            of the stocks in the screened universe to a rigorous analysis of
            company factors, such as strength of management, competitive
            industry position, and business prospects, and financial statement
            data, such as earnings, cash flows and profitability. The team may
            interview company management in making investment decisions. The
            Fund's capitalization criteria applies at the time of investment.

             The portfolio management team rescreens the universe frequently
            and seeks to consistently achieve a favorable balance of growth
            and value characteristics for the Fund. The team looks to sell a
            stock when it falls below the median ranking, has negative
            earnings surprises, or shows poor price performance relative to
            all stocks in the Fund's capitalization range or to companies in
            the same business sector. A stock may also be sold if its
            weighting in the portfolio becomes excessive (normally above 2% of
            the Fund's investments).

             The Fund intends to be fully invested in common stock (aside from
            certain cash management practices) and will not make defensive
            investments in response to unfavorable market and other
            conditions.

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 and the information to its
            right show performance of the Fund's Class A shares, but the
            returns do not reflect the impact of sales charges (loads). If
            they did, the returns would be lower than those shown. Unlike the
            bar chart, performance for Class A, B and C shares in the Average
            Annual Total Returns table reflects the impact of sales charges.
            For periods prior to the inception of Class A, B and C shares
            (1/13/97), performance information shown in the bar chart and
            tables for those classes is based on the performance of the Fund's
            Institutional Class shares, which are offered in a different
            prospectus. The prior Institutional Class performance has been
            adjusted to reflect the actual sales charges (in the Average
            Annual Total Returns table only), distribution and/or service
            (12b-1) fees, administrative fees and other expenses paid by Class
            A, B and C shares. Past performance is no guarantee of future
            results.

             net assets attributable in the aggregate to the Fund's Class A, B
             and C shares in excess of $2.5 billion, and 0.01% in other
             expenses attributable to that class during the most recent fiscal
             year.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class A, B or C 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 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.

              Category
              Growth Stocks


            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of "growth"
            companies with market capitalizations of between $100 million and
            $2 billion at the time of investment.

             The portfolio manager selects stocks for the Fund using a
            "growth" style. The portfolio manager seeks to identify companies
            with well-defined "wealth creating" characteristics, including
            superior earnings growth (relative to companies in the same
            industry or the market as a whole), high profitability and
            consistent, predictable earnings. In addition, through fundamental
            research, the portfolio manager seeks to identify companies that
            are gaining market share, have superior management and possess a
            sustainable competitive advantage, such as superior or innovative
            products, personnel and distribution systems. The Fund looks to
            sell a stock when the portfolio manager believes that its
            earnings, market sentiment or relative performance are
            disappointing or if an alternative investment is more attractive.

             The Fund may also invest to a limited degree in other kinds of
            equity securities, including preferred stocks and convertible
            securities. The Fund may invest up to 15% of its assets in foreign
            securities, except that it may invest without limit in American
            Depository Receipts (ADRs). The Fund may invest a substantial
            portion of its assets in the securities of smaller capitalization
            companies and securities issued in initial public offerings
            (IPOs). The Fund has in the past invested a significant portion of
            its assets in technology or technology-related companies, although
            there is no assurance that it will continue to do so in the
            future.

             In response to unfavorable market and other conditions, the Fund
            may make temporary investments of some or all of its assets in
            high-quality fixed income securities. This would be inconsistent
            with the Fund's investment objective and principal strategies.

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 and the information to its
            right show performance of the Fund's Class C shares, but the
            returns do not reflect the impact of sales charges (loads). If
            they did, the returns would be lower than those shown. Unlike the
            bar chart, performance for Class A, B and C shares in the Average
            Annual Total Returns table reflects the impact of sales charges.
            For periods prior to the inception of Class A shares (12/17/90)
            and Class B shares (4/1/99), performance information shown in the
            Average Annual Total Returns table for those classes is based on
            the performance of the Fund's Class C shares. The prior Class C
            performance has been adjusted to reflect the actual sales charges,
            distribution and/or service (12b-1) fees, administrative fees and
            other expenses paid by Class A and B shares. Prior to March 6,
            1999, the Fund had a different sub-adviser and would not
            necessarily have achieved the performance results shown on the
            next page under its current investment management arrangements.
            Past performance is no guarantee of future results.

                B and C shares in excess of $2.5 billion, and 0.01% in other
                expenses attributable to that class during the most recent

            Examples. The Examples are intended to help you compare the cost
            of investing in Class A, B or C 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 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 at least 65% of its assets in common stocks of companies
            with below-average valuations whose business fundamentals are
            expected to improve. Although the Fund typically invests in
            companies with market capitalizations of $1 billion to $10 billion
            at the time of investment, it may invest in companies in any
            capitalization range. To achieve income, the Fund invests a
            portion of its assets in income-producing (e.g., dividend-paying)
            stocks.

             The portfolio manager selects stocks for the Fund using a "value"
            style. The portfolio manager invests primarily in common stocks of
            companies having below-average valuations whose business
            fundamentals, such as market share, strength of management and
            competitive position, are expected to improve. The portfolio
            manager determines valuation based on characteristics such as
            price-to-earnings, price-to-book, and price-to-cash flow ratios.
            The portfolio manager analyzes stocks and seeks to identify the
            key drivers of financial results and catalysts for change, such as
            new management and new or improved products, that indicate a
            company may demonstrate improving fundamentals in the future. The
            portfolio manager looks to sell a stock when he believes that the
            company's business fundamentals are weakening or when the stock's
            valuation has become excessive.

             The Fund may also invest to a limited degree in other kinds of
            equity securities, including preferred stocks and convertible
            securities. The Fund may invest up to 15% of its assets in foreign
            securities, except that it may invest without limit in American
            Depository Receipts (ADRs).

             In response to unfavorable market and other conditions, the Fund
            may make temporary investments of some or all of its assets in
            high-quality fixed income securities. This would be inconsistent
            with the Fund's investment objective and principal strategies.

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

            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 and the information to its
            right show performance of the Fund's Class C shares, but the
            returns do not reflect the impact of sales charges (loads). If
            they did, the returns would be lower than those shown. Unlike the
            bar chart, performance for Class A, B and C shares in the Average
            Annual Total Returns table reflects the impact of sales charges.
            For periods prior to the inception of Class A shares (2/1/91) and
            Class B shares (5/22/95), performance information shown in the
            Average Annual Total Returns table for those classes is based on
            the performance of the Fund's Class C shares. The prior Class C
            performance has been adjusted to reflect the actual sales charges,
            distribution and/or service (12b-1) fees, administrative fees and
            other expenses paid by Class A and B shares. Prior to May 7, 1999,
            the Fund had a different sub-adviser and would not necessarily
            have achieved the performance results shown on the next page under
            its current investment management arrangements. Past performance
            is no guarantee of future results.

            (1) The Russell Mid-Cap Value Index is an unmanaged index that
                measures the performance of medium capitalization companies in
                the Russell 1000 Index with lower price-to-book ratios and
                lower forecasted growth values. It is not possible to invest
                directly in the index. The Russell Mid-Cap Value Index
                replaced the Russell 1000 Value Index (an unmanaged index that
                measures the performance of companies in the Russell 1000
                Index considered to have less than average growth orientation)
                and the S&P 500 Index (an unmanaged index of large
                capitalization common stocks) as the Fund's comparative index
                because PIMCO Advisors believes the Russell Mid-Cap Value
                Index is more representative of the Fund's investment
                strategies. For periods ended December 31, 1999, the 1 Year, 5
                Years, 10 Years and Fund Inception average annual total
                returns of the Russell 1000 Value Index were 7.34%, 23.08%,
                15.60% and 15.38%, respectively, and of the S&P 500 Index were
                21.04%, 28.56%, 18.21% and 19.06%, respectively.
            (2) The Lipper Multi-Cap Value Funds Average is a total return
                performance average of funds tracked by Lipper Analytical
                Services, Inc. that invest in companies with a variety of
                capitalization ranges without concentrating in any one market
                capitalization range over an extended period of time.

            (1) Due to the 12b-1 distribution fee imposed on Class B and Class

                the length of time the shares are held, pay more than the

                B and C shares in excess of $2.5 billion.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class A, B or C 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 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
              Growth Stocks


            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of "growth"
            companies with market capitalizations of at least $10 billion at
            the time of investment. The Fund normally invests in the
            securities of 15 to 25 issuers.

             The portfolio manager selects stocks for the Fund using a
            "growth" style. The portfolio manager seeks to identify companies
            with well-defined "wealth creating" characteristics, including
            superior earnings growth (relative to companies in the same
            industry or the market as a whole), high profitability and
            consistent, predictable earnings. In addition, through fundamental
            research, the portfolio manager seeks to identify companies that
            are gaining market share, have superior management and possess a
            sustainable competitive advantage, such as superior or innovative
            products, personnel and distribution systems. The Fund looks to
            sell a stock when the portfolio manager believes that its
            earnings, market sentiment or relative performance are
            disappointing or if an alternative investment is more attractive.
            The Fund is "non-diversified," which means that it invests in a
            relatively small number of issuers.

             The Fund may also invest to a limited degree in other kinds of
            equity securities, including preferred stocks and convertible
            securities. The Fund may invest up to 25% of its assets in foreign
            securities, except that it may invest without limit in American
            Depository Receipts (ADRs). The Fund has in the past invested a
            significant portion of its assets in technology or technology-
            related companies, although there is no assurance that it will
            continue to do so in the future. In response to unfavorable market
            and other conditions, the Fund may make temporary investments of
            some or all of its assets in high-quality fixed income securities.
            This would be inconsistent with the Fund's investment objective
            and principal strategies.

Performance
Information
            The top of the next page shows summary performance 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 and the information to its
            right show performance of the Fund's Institutional Class shares,
            which are offered in a different prospectus. This is because the
            Fund did not offer Class A, B or C shares during the periods
            shown. Although Institutional Class and Class A, B and C shares
            would have similar annual returns (because all the Fund's shares
            represent interests in the same portfolio of securities),
            Institutional Class performance would be higher than Class A, B or
            C performance because of the lower expenses and no sales charges
            (loads) paid by Institutional Class shares. The Average Annual
            Total Returns table also shows estimated historical performance
            for Class A, B and C shares based on the performance of the Fund's
            Institutional Class shares, adjusted to reflect the actual sales
            charges, distribution and/or service (12b-1) fees, administrative
            fees and other expenses paid by Class A, B and C shares. The
            performance information on the next page for periods prior to
            April 1, 2000 reflects the Fund's advisory fee rate in effect
            prior to that date (0.57% per annum); these results would have
            been lower had the Fund's current advisory fee rate (0.60% per
            annum) then been in effect. Prior to July 1, 1999, the Fund had a
            different sub-adviser and would not necessarily have achieved the
            performance results shown on the next page under its current
            investment management arrangements. In addition, the Fund changed
            its investment objective and policies on April 1, 2000; the
            performance results shown on the next page would not necessarily
            have been achieved had the Fund's current objective and policies
            then been in effect. Past performance is no guarantee of future
            results.

             and C shares in excess of $2.5 billion.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class A, B or C 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 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 at least 65% of its assets in an international portfolio
            of common stocks and other equity securities of companies located
            outside of the United States. Although the Fund normally invests
            in issuers from at least five different countries, it may at times
            invest in fewer than five countries, or even a single country. The
            Fund typically invests in approximately 30 to 60 stocks. Although
            the Fund invests primarily in developed market countries, it may
            also invest in developing, or "emerging," markets. The Fund has no
            other limits on geographic asset distribution and may invest in
            any foreign securities market in the world. The Fund may also
            invest in securities of foreign issuers traded on U.S. securities
            markets, but will normally not invest in U.S. issuers. The Fund
            invests most of its assets in foreign securities which trade in
            currencies other than the U.S. dollar and may invest directly in
            foreign currencies.

             The portfolio manager selects securities for the Fund using a
            research-driven "bottom-up" approach that seeks to utilize the
            Sub-Adviser's global research capabilities to identify companies
            with above-average long-term growth prospects and attractive
            valuations and that possess a sustainable competitive advantage,
            such as superior or innovative products, personnel and
            distribution systems. The portfolio manager seeks to select those
            stocks with the best long-term performance expectations, using a
            broad range of company fundamentals, such as long-term growth
            prospects, price-to-earnings ratios and other valuation measures,
            dividend and profit growth, balance sheet strength and return on
            assets. The portfolio managers sell stocks in order to adjust or
            rebalance the Fund's portfolio and to replace companies with
            weakening fundamentals.

             The Fund may invest a substantial portion of its assets in the
            securities of small and medium capitalization companies. The Fund
            may utilize foreign currency exchange contracts and derivative
            instruments (such as stock index futures contracts), primarily for
            portfolio management and hedging purposes. The Fund may to a
            limited degree invest in equity securities other than common
            stocks (such as equity-linked securities, preferred stocks and
            convertible securities) and may invest up to 10% of its assets in
            other investment companies. In response to unfavorable market and
            other conditions, the Funds may make temporary investments of some
            or all of its assets in foreign and domestic fixed income
            securities and in equity securities of U.S. issuers. This would be
            inconsistent with the Fund's investment objective and principal
            strategies.

Performance
Information The top of the next page shows summary performance 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 and the information to its
            right show performance of the Fund's Institutional Class shares,
            which are offered in a different prospectus. This is because the
            Fund did not offer Class A, B or C shares during the periods
            shown. Although Institutional Class and Class A, B and C shares
            would have similar annual returns (because all the Fund's shares
            represent interests in the same portfolio of securities),
            Institutional Class performance would be higher than Class A, B or
            C performance because of the lower expenses and no sales charges
            paid by Institutional Class shares. The Average Annual Total
            Returns table also shows estimated historical performance for
            Class A, B, and C shares based on the performance of the Fund's
            Institutional Class shares, adjusted to reflect the actual sales
            charges (loads), distribution and/or service (12b-1) fees,
            administrative fees and other expenses paid by Class A, B and C
            shares. The performance information on the next page for periods
            prior to May 8, 2000 reflects the Fund's advisory fee rate in
            effect prior to that date (0.85% per annum), which is lower than
            the current rate (0.75% per annum). Prior to November 1, 2000, the
            Fund had different sub-advisers and would not necessarily have
            achieved the performance results shown on the next page under its
            current investment management arrangements. In addition, the Fund
            changed its investment objective and policies on November 1, 2000;
            the performance results shown on the next page would not
            necessarily have been achieved had the Fund's current objective
            and policies then been in effect. Past performance is no guarantee
            of future results.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class A, B or C 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 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.

</TABLE>
            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of companies
            with market capitalizations of between $100 million and $1.5
            billion at the time of investment and below average P/E ratios
            relative to the market and their respective industry groups. To
            achieve income, the Fund invests a portion of its assets in
            income-producing (or dividend-paying) common stocks.

             The Fund's initial selection universe consists of approximately
            4,500 stocks of companies within the Fund's capitalization range.
            The portfolio managers screen this universe to identify
            approximately 500 undervalued stocks representing approximately
            160 industry groups. This screening process is based on a number
            of valuation factors, including P/E ratios (calculated both with
            respect to trailing operating earnings and forward earnings
            estimates) and price-to-sales, price-to-book value, and price-to-
            cash flow ratios. These factors are considered both on a relative
            basis (compared to other stocks in the same industry group) and on
            an absolute basis (compared to the overall market).

             From this narrowed universe, the portfolio managers select
            approximately 100 stocks for the Fund, each of which has close to
            equal weighting in the portfolio. They select stocks based on a
            quantitative analysis of factors including price momentum (based
            on changes in stock price relative to changes in overall market
            prices), earnings momentum (based on analysts' earnings per share
            estimates and revisions to those estimates), relative dividend
            yields and trading liquidity. The portfolio is also structured to
            have a maximum weighting of no more than 10% in any one industry.
            The portfolio managers may replace a stock if its market
            capitalization becomes excessive, if its valuation exceeds the
            average valuation of stocks represented in the S&P 500 Index, or
            when a stock within the same industry group has a considerably
            lower valuation than the Fund's current holding.

             Under normal circumstances, the Fund intends to be fully invested
            in common stocks (aside from certain cash management practices).
            The Fund may temporarily hold up to 10% of its assets in cash and
            cash equivalents for defensive purposes in response to unfavorable
            market and other conditions. This would be inconsistent with the
            Fund's investment objective and principal strategies.

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 and the information to its
            right show performance of the Fund's Class A shares, but the
            returns do not reflect the impact of sales charges (loads). If
            they did, the returns would be lower than those shown. Unlike the
            bar chart, performance for Class A, B and C shares in the Average
            Annual Total Returns table reflects the impact of sales charges.
            For periods prior to the inception of Class A, B and C shares
            (1/20/97), performance information shown in the bar chart and
            tables for those classes is based on the performance of the Fund's
            Institutional Class shares, which are offered in a different
            prospectus. The prior Institutional Class performance has been
            adjusted to reflect the actual sales charges (in the Average
            Annual Total Returns table only), distribution and/or service
            (12b-1) fees, administrative fees and other expenses paid by Class
            A, B and C shares. Past performance is no guarantee of future
            results.

            (1) Due to the 12b-1 distribution fee imposed on Class B and Class
                C shares, Class B or Class C shareholders may, depending upon
                the length of time the shares are held, pay more than the

                class, which is subject to a reduction of 0.05% on average daily
                net assets attributable in the aggregate to the Fund's Class A,
                B and C shares in excess of $2.5 billion, and 0.01% in other
                expenses attributed to that class during the most recent fiscal
                year.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class A, B or C 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 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 at least 65% of its assets in common stocks of "growth"
            companies with market capitalizations of between $1 billion and
            $10 billion at the time of investment.

             The portfolio managers select stocks for the Fund using a
            "growth" style. The portfolio managers seek to identify companies
            with well-defined "wealth creating" characteristics, including
            superior earnings growth (relative to companies in the same
            industry or the market as a whole), high profitability and
            consistent, predictable earnings. In addition, through fundamental
            research, the portfolio managers seek to identify companies that
            are gaining market share, have superior management and possess a
            sustainable competitive advantage, such as superior or innovative
            products, personnel and distribution systems. The Fund looks to
            sell a stock when the portfolio managers believe that its
            earnings, market sentiment or relative performance are
            disappointing or if an alternative investment is more attractive.

             The Fund may also invest to a limited degree in other kinds of
            equity securities, including preferred stocks and convertible
            securities. The Fund may invest up to 15% of its assets in foreign
            securities, except that it may invest without limit in American
            Depository Receipts (ADRs). The Fund has in the past invested a
            significant portion of its assets in technology or technology-
            related companies, although there is no assurance that it will
            continue to do so in the future.

             In response to unfavorable market and other conditions, the Fund
            may make temporary investments of some or all of its assets in
            high-quality fixed income securities. This would be inconsistent
            with the Fund's investment objective and principal strategies.

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

            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 and the information to its
            right show performance of the Fund's Class A shares, but the
            returns do not reflect the impact of sales charges (loads). If
            they did, the returns would be lower than those shown. Unlike the
            bar chart, performance for Class A, B and C shares in the Average
            Annual Total Returns table reflects the impact of sales charges.
            For periods prior to the inception of Class B shares (5/22/95),
            performance information shown in the Average Annual Total Returns
            table for that class is based on the performance of the Fund's
            Class A shares. The prior Class A performance has been adjusted to
            reflect the actual sales charges, distribution and/or service
            (12b-1) fees, administrative fees and other expenses paid by Class
            B shares. Prior to March 6, 1999, the Fund had a different sub-
            adviser and would not necessarily have achieved the performance
            results shown on the next page under its current investment
            management arrangements. Past performance is no guarantee of
            future results.

            (1) Due to the 12b-1 distribution fee imposed on Class B and Class
                C shares, Class B or Class C shareholders may, depending upon
                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 National Association of
                Securities Dealers, Inc.

            (2) Other Expenses reflects a 0.40% Administrative Fee paid by the
                class, which is subject to a reduction of 0.05% on average
                daily net assets attributable in the aggregate to the Fund's
                Class A, B and C shares in excess of $2.5 billion, and 0.01%
                in other expenses attributable to that class during the most
                recent fiscal year.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class A, B or C 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 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.

              of capital             the S&P 500 Index

                                     More than 200        annually


            The Fund attempts to provide a total return which exceeds the
            return of the S&P 500 Index by investing in a broadly diversified
            portfolio of at least 200 common stocks. The Fund also attempts to
            achieve higher after-tax returns for its shareholders by using a
            variety of tax-efficient management strategies.

             The Fund seeks to achieve its investment objective by normally
            investing at least 95% of its assets in stocks represented in the
            S&P 500 Index. The Fund's portfolio is designed to have certain
            characteristics that are similar to those of the index, including
            such measures as dividend yield, P/E ratio, relative volatility,
            economic sector exposure, return on equity and market price-to-
            book value ratio. The Fund's return is intended to correlate
            highly with the return of the S&P 500 Index, but the portfolio
            managers attempt to produce a higher total return than the index
            by selecting a portion of the stocks represented in the index
            using the quantitative techniques described below. The portfolio
            managers also use these techniques to make sell decisions.
            Notwithstanding these strategies, there is no assurance that the
            Fund's investment performance will equal or exceed that of the S&P
            500 Index.

             The Fund intends to be fully invested in common stock (aside from
            certain cash management practices) and will not make defensive
            investments in response to unfavorable market and other
            conditions.

             Quantitative Techniques. The portfolio managers use a proprietary
            quantitative model that ranks companies based on long-term (5-10
            years) price appreciation potential. They analyze factors such as
            growth of sustainable earnings and dividend behavior. Stocks in
            the top 50% of the model's ranking are considered for purchase by
            the Fund. The Fund looks to sell stocks selected from the bottom
            20% of the model's ranking based on cost, current market value and
            anticipated benefit of replacement. The portfolio managers' sell
            discipline also focuses on reducing realized capital gains as
            indicated below.

             Tax-Efficient Strategies. The portfolio managers utilize a range
            of active tax management strategies designed to minimize the
            Fund's taxable distributions, including low portfolio turnover and
            favoring investments in low-dividend, growth-oriented companies.
            The portfolio managers also identify specific shares of stock to
            be sold that have the lowest tax cost. When prudent, stocks are
            also sold to realize capital losses in order to offset realized
            capital gains. In limited circumstances, the Fund may also
            distribute appreciated securities to shareholders to meet
            redemption requests so as to avoid realizing capital gains.
            Despite the use of these tax-efficient strategies, the Fund may
            realize gains and shareholders will incur tax liability from time
            to time.

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          . Growth Securities Risk
                                                          . Credit Risk
              . Issuer Risk          . Leveraging Risk    . Management Risk
              . Value Securities Risk. Focused Investment 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 and the information to its
            right show performance of the Fund's Class A shares, but the
            returns do not reflect the impact of sales charges (loads). If
            they did, the returns would be lower than those shown. Unlike the
            bar chart, performance for Class A, B and C shares in the Average
            Annual Total Returns table reflects the impact of sales charges.
            Past performance is no guarantee of future results.

            (1) Due to the 12b-1 distribution fee imposed on Class B and Class
                C shares, Class B or Class C shareholders may, depending upon
                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 National Association of
                Securities Dealers, Inc.

            (2) Other Expenses reflects a 0.40% Administrative Fee paid by the
             class, which is subject to a reduction of 0.05% on average daily
             net assets attributable in the aggregate to the Fund's Class A, B
             and C shares in excess of $2.5 billion, and 0.01% in other
             expenses attributable to that class during the most recent fiscal
             year.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class A, B or C 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 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 at least 65% of its assets in common stocks of companies
            with market capitalizations of more than $5 billion at the time of
            investment and below-average valuations whose business
            fundamentals are expected to improve. To achieve income, the Fund
            invests a portion of its assets in income-producing (e.g.,
            dividend-paying) common stocks.

             The portfolio manager selects stocks for the Fund using a "value"
            style. The portfolio manager invests primarily in stocks of
            companies having below-average valuations whose business
            fundamentals are expected to improve. The portfolio manager
            determines valuation based on characteristics such as price-to-
            earnings, price-to-book, and price-to-cash flow ratios. The
            portfolio manager analyzes stocks and seeks to identify the key
            drivers of financial results and catalysts for change, such as new
            management and new or improved products, that indicate a company
            may demonstrate improving fundamentals in the future. The
            portfolio manager looks to sell a stock when he believes that the
            company's business fundamentals are weakening or when the stock's
            valuation has become excessive.

             The Fund may also invest to a limited degree in other kinds of
            equity securities, including preferred stocks and convertible
            securities. The Fund may invest up to 15% of its assets in foreign
            securities, except that it may invest without limit in American
            Depository Receipts (ADRs). In response to unfavorable market and
            other conditions, the Fund may make temporary investments of some
            or all of its assets in high-quality fixed income securities. This
            would be inconsistent with the Fund's investment objective and
            principal strategies.

--------------------------------------------------------------------------------
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         . Foreign Investment Risk
                                                        . Credit Risk
              . Issuer Risk         . Currency Risk     . Management Risk
              . Value Securities Risk

                                    . Focused Investment 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 and the information to its
            right show performance of the Fund's Class A shares, but the
            returns do not reflect the impact of sales charges (loads). If
            they did, the returns would be lower than those shown. Unlike the
            bar chart, performance for Class A, B and C shares in the Average
            Annual Total Returns table reflects the impact of sales charges.
            For periods prior to the inception of Class A, B and C shares
            (1/13/97), performance information shown in the bar chart and
            tables for those classes is based on the performance of the Fund's
            Institutional Class shares, which are offered in a different
            prospectus. The prior Institutional Class performance has been
            adjusted to reflect the actual sales charges (in the Average
            Annual Total Returns table only), distribution and/or service
            (12b-1) fees, administrative fees and other expenses paid by Class
            A, B and C shares. Prior to May 8, 2000, the Fund had a different
            sub-adviser and would not necessarily have achieved the
            performance results shown on the next page under its current
            investment management arrangements. Past performance is no
            guarantee of future results.

            (1) The Russell 1000 Value Index is an unmanaged index that
                measures the performance of companies in the Russell 1000
                Index considered to have less than average growth orientation.
                It is not possible to invest directly in the index. The
                Russell 1000 Value Index replaced the S&P 500 Index (an
                unmanaged index of large capitalization common stocks.) as the
                Fund's comparative index because PIMCO Advisors believes that
                the Russell 1000 Value Index is more representative of the
                Fund's investment strategies. For periods ended December 31,
                1999, the 1 Year, 5 Year and Fund Inception average annual
                total returns of the S&P 500 Index were 21.04%, 28.56% and
                19.70%, respectively.
            (2) The Lipper Multi-Cap Value Funds Average is a total return
                performance average of funds tracked by Lipper Analytical
                Services, Inc. that invest in companies with a variety of
                capitalization ranges, without concentrating in any one market
                capitalization range over an extended period of time. It does
                not take into account sales charges.

            (1) Due to the 12b-1 distribution fee imposed on Class B and Class
                C shares, Class B or Class C shareholders may, depending upon
                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 National Association of

                net assets attributable in the aggregate to the Fund's Class A,
                B and C shares in excess of $2.5 billion, and 0.01% in other
                expenses attributable to that class during the most recent
                fiscal year.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class A, B or C 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 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 summarized 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.

Market      The market price of securities owned by a Fund may go up or down,
Risk        sometimes rapidly or unpredictably. Each of the Funds normally
            invests most of its assets in common stocks and/or other equity
            securities. A principal risk of investing in each Fund is that the
            equity securities in its portfolio will decline in value due to
            factors affecting equity securities markets generally or
            particular industries represented in those markets. The values of
            equity securities 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 also decline for a number of reasons
Risk        which directly relate to the issuer, such as management
            performance, financial leverage and reduced demand for the
            issuer's goods or services.

Value
Securities  Each Fund may invest in companies that may not be expected to
Risk        experience significant earnings growth, but whose securities its
            portfolio manager believes are selling at a price lower than their
            true value. The Capital Appreciation, Equity Income, Growth &
            Income, International, Mid-Cap, Renaissance, Allianz Select
            International, Small-Cap Value, Tax-Efficient Equity and Value
            Funds may place particular emphasis on value securities. Companies
            that issue value securities may have experienced adverse business
            developments or may be subject to special risks that have caused
            their securities to be out of favor. If a portfolio manager's
            assessment of a company's prospects is wrong, or if the market
            does not recognize the value of the company, the price of its
            securities may decline or may not approach the value that the
            portfolio manager anticipates.

Growth
Securities  Each Fund may invest in equity securities of companies that its
Risk        portfolio manager believes will experience relatively rapid
            earnings growth. The Capital Appreciation, Global Innovation,
            Growth, Growth & Income, Innovation, International Mid-Cap,
            Opportunity, Select Growth, Allianz Select International, Target
            and Tax-Efficient Equity Funds may place particular emphasis on
            growth securities. Growth securities typically trade at higher
            multiples of current earnings than other securities. Therefore,
            the values of growth securities may be more sensitive to changes
            in current or expected earnings than the values of other
            securities.

Smaller
Company
Risk        The general risks associated with equity securities and liquidity
            risk are particularly pronounced for securities of companies with
            smaller market capitalizations. These companies may have limited
            product lines, markets or financial resources or they may depend
            on a few key employees. Securities of smaller companies may trade
            less frequently and in lesser volume than more widely held
            securities and their values may fluctuate more sharply than other
            securities. They may also trade in the over-the-counter market or
            on a regional exchange, or may otherwise have limited liquidity.
            The Global Innovation, Innovation, Opportunity and Small-Cap Value
            Funds generally have substantial exposure to this risk. The Growth
            & Income, Mid-Cap, Allianz Select International and Target Funds
            also have significant exposure to this risk because they invest
            substantial assets in companies with medium-sized market
            capitalizations, which are smaller and generally less-seasoned
            than the largest companies.

IPO Risk

            The Funds, particularly the Global Innovation Fund, may purchase
            securities in initial public offerings (IPOs). These securities
            are subject to many of the same risks as investing in companies
            with smaller market capitalizations. Securities issued in IPOs
            have no trading history, and information about the

37 PIMCO Funds: Multi-Manager Series
<PAGE>


            companies may be available for very limited periods. In addition,
            the prices of securities sold in IPOs may be highly volatile. At
            any particular time or from time to time a Fund may not be able to
            invest in securities issued in IPOs, or invest to the extent
            desired, because, for example, only a small portion (if any) of
            the securities being offered in an IPO may be made available to
            the Fund. In addition, under certain market conditions a
            relatively small number of companies may issue securities in IPOs.
            Similarly, as the number of Funds to which IPO securities are
            allocated increases, the number of securities issued to any one
            Fund may decrease. The investment performance of a Fund during
            periods when it is unable to invest significantly or at all in
            IPOs may be lower than during periods when the Fund is able to do
            so. In addition, as a Fund increases in size, the impact of IPOs
            on the Fund's performance will generally decrease.


Liquidity   All of the Funds are subject to liquidity risk. Liquidity risk
Risk        exists when particular investments are difficult to purchase or
            sell, possibly preventing a Fund from selling such illiquid
            securities at an advantageous time or price. Funds with principal
            investment strategies that involve securities of companies with
            smaller market capitalizations, foreign securities, derivatives or
            securities with substantial market and/or credit risk tend to have
            the greatest exposure to liquidity risk.

Derivatives All Funds except the Capital Appreciation, Mid-Cap and Small-Cap
Risk        Value Funds may use derivatives, which are financial contracts
            whose 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 may sometimes use derivatives
            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, which increases opportunities for gain
            but also involves greater risk of loss due to 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,
            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. In addition, a Fund's
            use of derivatives may increase or accelerate the amount of taxes
            payable by shareholders. 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.

Sector
Specific Risks

            In addition to other risks, Funds that invest a substantial
            portion of their assets in related industries (or "sectors") may
            have greater risk because companies in these sectors may share
            common characteristics and may react similarly to market
            developments.

            Technology Related Risk. Because the Global Innovation and
            Innovation Funds concentrate their investments in companies which
            utilize innovative technologies, they are subject to risks
            particularly affecting those companies, such as the risks of short
            product cycles and rapid obsolescence of products and services,
            competition from new and existing companies, significant losses
            and/or limited earnings, security price volatility and limited
            operating histories. Other Funds may also be subject to these
            risks to the extent they invest their assets in technology or
            technology-related companies.

Foreign
(non-       A Fund that invests in foreign securities, and particularly the
U.S.)       Global Innovation, International and Allianz Select International
Investment  Funds, may experience more rapid and extreme changes in value than
Risk        Funds that invest exclusively in securities of U.S. issuers or
            securities that trade exclusively in U.S. markets. The securities
            markets of many foreign countries are relatively small, with a
            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. To the extent that a Fund, such as the Global
            Innovation, International or Allianz Select International Fund,
            invests a significant portion of its assets in a narrowly defined
            area such as Europe, Asia or South America, the Fund will
            generally have more exposure to regional economic risks associated
            with foreign investments. Adverse conditions in certain regions
            (such as Southeast Asia) can also adversely affect securities of
            other countries whose economies appear to be unrelated. In
            addition, special U.S. tax considerations may apply to a Fund's
            investment in foreign securities.

                                                                   Prospectus 38
<PAGE>

Emerging
Markets     Foreign investment risk may be particularly high to the extent
Risk        that a Fund invests in emerging market securities of issuers based
            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. The Global Innovation,
            International and Allianz Select International Funds may invest
            significant portions of their assets in emerging market
            securities. In addition, the risks associated with investing in a
            narrowly defined geographic area (discussed above under "Foreign
            (non-U.S.) Investment Risk") are generally more pronounced with
            respect to investments in emerging market countries.

Currency
Risk        Funds that invest directly in foreign currencies or in securities
            that trade in, and receive revenues in, foreign 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. The Global Innovation, International and
            Allianz Select International Funds are particularly sensitive to
            currency risk. 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.

Focused
Investment  Focusing Fund investments in a small number of issuers, industries
Risk        or foreign currencies or regions increases risk. Funds, such as
            the Select Growth Fund, that are "non-diversified" because they
            invest in a relatively small number of issuers may have more risk
            because changes in the value of a single security or the impact of
            a single economic, political or regulatory occurrence may have a
            greater adverse impact on the Fund's net asset value. Some of
            those issuers also may present substantial credit or other risks.
            The Global Innovation, International and Allianz Select
            International Funds may be subject to increased risk to the extent
            that they focus their investments in securities denominated in a
            particular foreign currency or in a narrowly defined geographic
            area outside the U.S., because companies in these areas may share
            common characteristics and are often subject to similar business
            risks and regulatory burdens, and their securities may react
            similarly to economic, market, political or other developments.
            Similarly, the Global Innovation and Innovation Funds are
            vulnerable to events affecting companies which use innovative
            technologies to gain a strategic, competitive advantage in their
            industry and companies that provide and service those technologies
            because these Funds normally "concentrate" their investments in
            those companies. Also, the Funds may from time to time have
            greater risk to the extent they invest a substantial portion of
            their assets in companies in related industries such as
            "technology" or "financial and business services," which may share
            common characteristics, are often subject to similar business
            risks and regulatory burdens, and whose securities may react
            similarly to economic, market, political or other developments.

Leveraging
Risk        Leverage, including borrowing, will cause the value of a Fund's
            shares to be more volatile than if the Fund did not use leverage.
            This is because leverage tends to exaggerate the effect of any
            increase or decrease in the value of a Fund's portfolio
            securities. The Funds, and in particular the Global Innovation,
            International and Tax-Efficient Equity Funds, may engage in
            transactions or purchase instruments that give rise to forms of
            leverage. Such transactions and instruments may include, among
            others, the use of reverse repurchase agreements and other
            borrowings, the investment of collateral from loans of portfolio
            securities, or the use of when-issued, delayed-delivery or forward
            commitment transactions. The use of derivatives may also involve
            leverage. The use of leverage may also cause a Fund to liquidate
            portfolio positions when it would not be advantageous to do so in
            order to satisfy its obligations or to meet segregation
            requirements.

Interest
Rate Risk   To the extent that Funds purchase fixed income securities for
            investment or defensive purposes, they will be subject to interest
            rate risk, a market risk relating to investments in fixed income
            securities such as bonds and notes. The Growth & Income Fund is
            particularly sensitive to this risk because it may invest in
            interest rate sensitive securities such as corporate bonds.

             As interest rates rise, the value of fixed income securities in a
            Fund's portfolio are likely to decrease. Securities with longer
            "durations" (defined below) tend to be more sensitive to changes
            in interest rates, usually making them more volatile than
            securities with shorter durations. 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. Generally, 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      All of the Funds are subject to credit risk. This is the risk that
Risk        the issuer or the guarantor of a fixed 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 their credit ratings.

High
Yield       Funds that invest in high yield securities and unrated securities
Risk        of similar quality (commonly known as "junk bonds") may be subject
            to greater levels of interest rate, credit and liquidity risk than
            Funds that do not invest in such securities. The Growth & Income
            Fund is particularly susceptible to this risk. These securities
            are considered predominantly 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 these securities and reduce
            a Fund's ability to sell them.

Management  Each Fund is subject to management risk because it is an actively
Risk        managed investment portfolio. PIMCO Advisors, the Sub-Advisers 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.

            partnerships had approximately $272 billion in assets under
            management.

             PIMCO Advisors has retained investment management firms ("Sub-
            Advisers") to manage each Fund's investments, except that the
            PIMCO Equity Advisors division of PIMCO Advisors manages the
            investments of the Equity Income, Global Innovation, Growth,
            Growth & Income, Innovation, Opportunity, Renaissance, Select

            Advisers" below.

             PIMCO Advisors has retained its affiliate, Pacific Investment
            Management Company LLC ("Pacific Investment Management Company"),

            the Funds in its capacity as sub-administrator. PIMCO Advisors and
            the sub-administrator may retain other affiliates to provide
            certain of these services.

            the advisory fees it receives to the Sub-Adviser in return for its
            services.

            Investment Options -- Class A, B and C Shares

            The Trust offers investors Class A, Class B and Class C shares of
            each Fund in this Prospectus. Each class of shares is subject to
            different types and levels of sales charges than the other classes
            and bears a different level of expenses.

             The class of shares that is best for you depends upon a number of
            factors, including the amount and the intended length of your
            investment. The following summarizes key information about each
            class to help you make your investment decision, including the
            various expenses associated with each class. More extensive
            information about the Trust's multi-class arrangements is included
            in the PIMCO Funds Shareholders' Guide for Class A, B and C Shares
            (the "Guide"), which is included as part of the Statement of
            Additional Information and can be obtained free of charge from the
            Distributor. See "How to Buy and Sell Shares--PIMCO Funds
            Shareholders' Guide" below.

Class A     . You pay an initial sales charge of up to 5.50% when you buy
Shares        Class A shares. The sales charge is deducted from your
              investment so that not all of your purchase payment is invested.

            . You may be eligible for a reduction or a complete waiver of the
              initial sales charge under a number of circumstances. For
              example, you normally pay no sales charge if you purchase
              $1,000,000 or more of Class A shares. Please see the Guide for
              details.

            . Class A shares are subject to lower 12b-1 fees than Class B or
              Class C shares. Therefore, Class A shareholders generally pay
              lower annual expenses and receive higher dividends than Class B
              or Class C shareholders.

            . You normally pay no contingent deferred sales charge ("CDSC")
              when you redeem Class A shares, although you may pay a 1% CDSC
              if you purchase $1,000,000 or more of Class A shares (and
              therefore pay no initial sales charge) and then redeem the
              shares during the first 18 months after your initial purchase.
              The Class A CDSC is waived for certain categories of investors and
              does not apply if you are otherwise eligible to purchase Class A
              shares without a sales charge. Please see the Guide for details.

Class B     . You do not pay an initial sales charge when you buy Class B
Shares        shares. The full amount of your purchase payment is invested
              initially.

            . You normally pay a CDSC of up to 5% if you redeem Class B shares
              during the first six years after your initial purchase. The
              amount of the CDSC declines the longer you hold your Class B
              shares. You pay no CDSC if you redeem during the seventh year and
              thereafter. The Class B CDSC is waived for certain categories of
              investors. Please see the Guide for details.

            . Class B shares are subject to higher 12b-1 fees than Class A
              shares for the first seven years they are held. During this time,
              Class B shareholders normally pay higher annual expenses and
              receive lower dividends than Class A shareholders.

            . Class B shares automatically convert into Class A shares after
              they have been held for seven years. After the conversion takes
              place, the shares are subject to the lower 12b-1 fees paid by
              Class A shares.

Class C     . You do not pay an initial sales charge when you buy Class C
Shares        shares. The full amount of your purchase payment is invested
              initially.

            . You normally pay a CDSC of 1% if you redeem Class C shares
              during the first year after your initial purchase. The Class C
              CDSC is waived for certain categories of investors. Please see
              the Guide for details.

            . Class C shares are subject to higher 12b-1 fees than Class A
              shares. Therefore, Class C shareholders normally pay higher
              annual expenses and receive lower dividends than Class A
              shareholders.

            . Class C shares do not convert into any other class of shares.
              Because Class B shares convert into Class A shares after seven
              years, Class C shares will normally be subject to higher expenses
              and will pay lower dividends than Class B shares if the shares are
              held for more than seven years.

            The following provides additional information about the sales
            charges and other expenses associated with Class A, Class B and
            Class C shares.

                                                                   Prospectus 46

CDSCs on    Unless a waiver applies, investors who purchase $1,000,000 or more
Class A     of Class A shares (and, thus, pay no initial sales charge) will be
Shares      subject to a 1% CDSC if the shares are redeemed within 18 months
            of their purchase. The Class A CDSC does not apply if you are
            otherwise eligible to purchase Class A shares without an initial
            sales charge or if you are eligible for a waiver of the CDSC. See
            "Reductions and Waivers of Initial Sales Charges and CDSCs" below.

--------------------------------------------------------------------------------
How CDSCs   A CDSC is imposed on redemptions of Class B and Class C shares
are         (and where applicable, Class A shares) on the amount of the
Calculated  redemption which causes the current value of your account for the
            particular class of shares of a Fund to fall below the total
            dollar amount of your purchase payments subject to the CDSC.
            However, no CDSC is imposed if the shares redeemed have been
            acquired through the reinvestment of dividends or capital gains
            distributions or if the amount redeemed is derived from increases
            in the value of your account above the amount of the purchase
            payments subject to the CDSC. CDSCs are deducted from the proceeds
            of your redemption, not from amounts remaining in your account. In
            determining whether a CDSC is payable, it is assumed that the
            purchase payment from which the redemption is made is the earliest
            purchase payment for the particular class of shares in your
            account (from which a redemption or exchange has not already been
            effected).

            For instance, the following example illustrates the operation of
            the Class B CDSC:

            . Assume that an individual opens an account and makes a purchase
              payment of $10,000 for Class B shares of a Fund and that six
              months later the value of the investor's account for that Fund
              has grown through investment performance and reinvestment of
              distributions to $11,000. The investor then may redeem up to
              $1,000 from that Fund ($11,000 minus $10,000) without incurring
              a CDSC. If the investor should redeem $3,000, a CDSC would be
              imposed on $2,000 of the redemption (the amount by which the
              investor's account for the Fund was reduced below the amount of
              the purchase payment). At the rate of 5%, the Class B CDSC would
              be $100.

              In determining whether an amount is available for redemption
            without incurring a CDSC, the purchase payments made for all
            shares of a particular class of a Fund in the shareholder's
            account are aggregated, and the current value of all such shares
            is aggregated.

--------------------------------------------------------------------------------
Reductions  The initial sales charges on Class A shares and the CDSCs on Class
and         A, Class B and Class C shares may be reduced or waived under
Waivers     certain purchase arrangements and for certain categories of
of          investors. Please see the Guide for details. The Guide is

Distribu-   The Funds pay fees to the Distributor on an ongoing basis as
tion        compensation for the services the Distributor renders and the
and         expenses it bears in connection with the sale and distribution of
Servicing   Fund shares ("distribution fees") and/or in connection with
(12b-1)     personal services rendered to Fund shareholders and the
Plans       maintenance of shareholder accounts ("servicing fees"). These
            payments are made pursuant to Distribution and Servicing Plans
            ("12b-1 Plans") adopted by each Fund pursuant to Rule 12b-1 under
            the Investment Company Act of 1940.

             There is a separate 12b-1 Plan for each class of shares offered
            in this Prospectus. Class A shares pay only servicing fees. Class
            B and Class C shares pay both distribution and servicing fees. The
            following lists the maximum annual rates at which the distribution
            and/or servicing fees may be paid under each 12b-1 Plan
            (calculated as a percentage of each Fund's average daily net
            assets attributable to the particular class of shares):

</TABLE>

             Because 12b-1 fees are paid out of a Fund's assets on an ongoing
            basis, over time these fees will increase the cost of your
            investment and may cost you more than sales charges which are
            deducted at the time of investment. Therefore, although Class B
            and Class C shares do not pay initial sales charges, the
            distribution fees payable on Class B and Class C shares may, over
            time, cost you more than the initial sales charge imposed on Class
            A shares. Also, because Class B shares convert into Class A shares
            after they have been held for seven years and are not subject to
            distribution fees after the conversion, an investment in Class C
            shares may cost you more over time than an investment in Class B
            shares.

            How Fund Shares Are Priced

            The net asset value ("NAV") of a Fund's Class A, Class B and Class
            C 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 the 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 quotes are not readily
            available may be valued, pursuant to procedures established by the
            Board of Trustees, with reference to other securities or 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

                                                                   Prospectus 48

            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. In particular, calculation of the NAV
            of the Global Innovation, International and Allianz Select
            International Funds may not take place contemporaneously with the
            determination of the prices of foreign securities used in NAV
            calculations.

             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 their 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 or persons acting at their direction pursuant to
            procedures approved by the Board of Trustees. Fair valuation may
            also be used by the Board of Trustees if extraordinary events
            occur after the close of the relevant market but prior to the NYSE
            Close.

            How to Buy and Sell Shares

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

PIMCO       More detailed information about the Trust's purchase, sale and
Funds       exchange arrangements for Fund shares is provided in the PIMCO
Share-      Funds Shareholders' Guide, which is included in the Statement of
holder's    Additional Information and can be obtained free of charge from the
Guide       Distributor by written request or by calling 1-800-426-0107. The
            Guide provides technical information about the basic arrangements
            described below and also describes special purchase, sale and
            exchange features and programs offered by the Trust, including:

            . Automated telephone and wire transfer procedures
            . Automatic purchase, exchange and withdrawal programs
            . Programs that establish a link from your Fund account to your
              bank account
            . Special arrangements for tax-qualified retirement plans
            . Investment programs which allow you to reduce or eliminate the
              initial sales charges on Class A shares
            . Categories of investors that are eligible for waivers or
              reductions of initial sales charges and CDSCs

Calculation When you buy shares of the Funds, you pay a price equal to the NAV
of Share    of the shares, plus any applicable sales charge. When you sell
Price and   (redeem) shares, you receive an amount equal to the NAV of the
Redemption  shares, minus any applicable CDSC. NAVs are determined at the
Payments    close of regular trading (normally, 4:00 p.m., Eastern time) on
            the New York Stock Exchange on each day the New York Stock
            Exchange is open. See "How Fund Shares Are Priced" above 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. There are certain exceptions where an
            order is received by a broker or dealer prior to the close of
            regular trading on the New York Stock Exchange and then
            transmitted to the Distributor after the NAV has been calculated
            for that day (in which case the order may be processed at that
            day's NAV). Please see the Guide for details.

             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 (at
            the succeeding day's NAV).

Buying      You can buy Class A, Class B or Class C shares of the Funds in the
Shares      following ways:

             . Through your broker, dealer or other financial intermediary.
               Your broker, dealer or other intermediary may establish higher
               minimum investment requirements than the Trust and may also
               independently charge you transaction fees and additional
               amounts (which may vary) in return for its services, which will
               reduce your return. Shares you purchase through your broker,
               dealer or other intermediary will normally be held in your
               account with that firm.

             . Directly from the Trust. To make direct investments, you must
               open an account with the Distributor and send payment for your
               shares either by mail or through a variety of other purchase
               options and plans offered by the Trust.

             If you wish to invest directly by mail, please send a check
            payable to PIMCO Funds Distributors LLC, along with a completed
            application form to:

                                    PIMCO Funds Distributors LLC

                                    Providence, RI 02940-0926

             The Trust accepts all purchases by mail subject to collection of
            checks at full value and conversion into federal funds. You may
            make subsequent purchases by mailing a check to the address above
            with a letter describing the investment or with the additional
            investment portion of a confirmation statement. Checks for
            subsequent purchases should be payable to PIMCO Funds Distributors
            LLC and should clearly indicate your account number. Please call
            the Distributor at 1-800-426-0107 if you have any questions
            regarding purchases by mail.

             The Guide describes a number of additional ways you can make
            direct investments, including through the PIMCO Funds Auto-Invest
            and PIMCO Funds Fund Link programs. You can obtain a Guide free of
            charge from the Distributor by written request or by calling 1-
            800-426-0107. See "PIMCO Funds Shareholders' Guide" above.

             The Distributor, in its sole discretion, may accept or reject any
            order for purchase of Fund shares. No share certificates will be
            issued unless specifically requested in writing.

Investment  The following investment minimums apply for purchases of Class A,
Minimums    Class B and Class C shares.

</TABLE>

             Lower minimums may apply for certain categories of investors,
            including certain tax-qualified retirement plans, and for special
            investment programs and plans offered by the Trust, such as the
            PIMCO Funds Auto-Invest and PIMCO Funds Fund Link programs. Please
            see the Guide for details.

Small       Because of the disproportionately high costs of servicing accounts
Account     with low balances, if you have a direct account with the
Fee         Distributor, you will be charged a fee at the annual rate of $16
            if your account balance for any Fund falls below a minimum level
            of $2,500, except for Uniform Gift to Minors, IRA, Roth IRA and
            Auto-Invest accounts for which the limit is $1,000. The fee also
            applies to employer-sponsored retirement plan accounts, Money
            Purchase and/or Profit Sharing plans, 401(k) plans, 403(b)(7)
            custodial accounts, SIMPLE IRAs, SEPs and SAR/SEPs. (A separate
            custodial fee may apply to IRAs, Roth IRAs and other retirement
            accounts.) However, you will not be charged this fee if the
            aggregate value of all of your PIMCO Funds accounts is at least
            $50,000. Any applicable small account fee will be deducted
            automatically from your below-minimum Fund account in quarterly
            installments and paid to the Administrator. Each Fund account will
            normally be valued, and any deduction taken, during the last five
            business days of each calendar quarter. Lower minimum balance
            requirements and waivers of the small account fee apply for
            certain categories of investors. Please see the Guide for details.

Minimum     Due to the relatively high cost to the Funds of maintaining small
Account     accounts, you are asked to maintain an account balance in each
Size        Fund in which you invest of at least the minimum investment
            necessary to open the particular type of account. If your balance
            for any Fund remains below the minimum for three months or longer,
            the Administrator has the right (except in the case of employer-
            sponsored retirement accounts) to redeem your remaining shares and
            close that Fund account after giving you 60 days to increase your
            balance. Your Fund account will not be liquidated if the reduction
            in size is due solely to a decline in market value of your Fund
            shares or if the aggregate value of all your PIMCO Funds accounts
            exceeds $50,000.

                                                                   Prospectus 50

Exchanging  Except as provided below and/or in the applicable Funds' or
Shares      series' prospectus(es), you may exchange your Class A, Class B or
            Class C shares of any Fund for the same Class of shares of any
            other Fund or of another series of the Trust or PIMCO Funds:
            Pacific Investment Management Series. 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. Exchanges are subject to
            the $2,500 minimum initial purchase requirements for each Fund,
            except with respect to tax-qualified programs and exchanges
            effected through the PIMCO Funds Auto-Exchange plan. In addition,
            an exchange is generally a taxable event which will generate
            capital gains or losses, and special rules may apply in computing
            tax basis when determining gain or loss. If you maintain your
            account with the Distributor, you may exchange shares by
            completing a written exchange request and sending it to PIMCO
            Funds Distributors LLC, P.O. Box 9688, Providence, RI 02940-0926.
            You can get an exchange form by calling the Distributor at 1-800-
            426-0107.

             The Trust reserves the right to refuse exchange purchases if, in
            the judgment of PIMCO Advisors, 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 Advisors 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 PIMCO 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 preceeding sentence, it
            reserves the right to do so at any time. Except as otherwise
            permitted by the Securities and Exchange Commission, the Trust
            will give you 60 days' advance notice if it exercises its right to
            terminate or materially modify the exchange privilege with respect
            to Class A, B and C shares.

             The Guide provides more detailed information about the exchange
            privilege, including the procedures you must follow and additional
            exchange options. You can obtain a Guide free of charge from the
            Distributor by written request or by calling 1-800-426-0107. See
            "PIMCO Funds Shareholders' Guide" above.

Selling     You can sell (redeem) Class A, Class B or Class C shares of the
Shares      Funds in the following ways:

              . Through your broker, dealer or other financial intermediary.
            Your broker, dealer or other intermediary may independently charge
            you transaction fees and additional amounts (which may vary) in
            return for its services, which will reduce your return.

              . Directly from the Trust by Written Request. To redeem shares
            directly from the Trust by written request (whether or not the
            shares are represented by certificates), you must send the
            following items to the Trust's Transfer Agent, PFPC, Inc., P.O.
            Box 9688, Providence, RI 02940-0926:

              (1) a written request for redemption signed by all registered
              owners exactly as the account is registered on the Transfer
              Agent's records, including fiduciary titles, if any, and
              specifying the account number and the dollar amount or number of
              shares to be redeemed;

              (2) for certain redemptions described below, a guarantee of all
              signatures on the written request or on the share certificate or
              accompanying stock power, if required, as described under
              "Signature Guarantee" below;

              (3) any share certificates issued for any of the shares to be
              redeemed (see "Certificated Shares" below); and

              (4) any additional documents which may be required by the
              Transfer Agent for redemption by corporations, partnerships or
              other organizations, executors, administrators, trustees,
              custodians or guardians, or if the redemption is requested by
              anyone other than the shareholder(s) of record. Transfers of
              shares are subject to the same requirements.

             A signature guarantee is not required for redemptions requested
            by and payable to all shareholders of record for the account that
            is to be sent to the address of record for that account. To avoid
            delay in redemption or transfer, if you have any questions about
            these requirements you should contact the Transfer Agent in
            writing or call 1-800-426-0107 before submitting a request.
            Written redemption or
            transfer requests will not be honored until all required documents
            in the proper form have been received by the Transfer Agent. You
            can not redeem your shares by written request to the Trust if they
            are held in broker "street name" accounts--you must redeem through
            your broker.

             If the proceeds of your redemption (i) are to be paid to a person
            other than the record owner, (ii) are to be sent to an address
            other than the address of the account on the Transfer Agent's
            records,

            or (iii) are to be paid to a corporation, partnership, trust or
            fiduciary, the signature(s) on the redemption request and on the
            certificates, if any, or stock power must be guaranteed as
            described under "Signature Guarantee" below. The Distributor may,
            however, waive the signature guarantee requirement for redemptions
            up to $2,500 by a trustee of a qualified retirement plan, the
            administrator for which has an agreement with the Distributor.

             The Guide describes a number of additional ways you can redeem
            your shares, including:

                . Telephone requests to the Transfer Agent
                . PIMCO Funds Automated Telephone System (ATS)
                . Expedited wire transfers
                . Automatic Withdrawal Plan
                . PIMCO Funds Fund Link

             Unless you specifically elect otherwise, your initial account
            application permits you to redeem shares by telephone subject to
            certain requirements. To be eligible for ATS, expedited wire
            transfer, Automatic Withdrawal Plan, and Fund Link privileges, you
            must specifically elect the particular option on your account
            application and satisfy certain other requirements. The Guide
            describes each of these options and provides additional
            information about selling shares. You can obtain a Guide free of
            charge from the Distributor by written request or by calling 1-
            800-426-0107.

             Other than an applicable CDSC, you will not pay any special fees
            or charges to the Trust or the Distributor when you sell your
            shares. However, if you sell your shares through your broker,
            dealer or other financial intermediary, that firm may charge you a
            commission or other fee for processing your redemption request.

             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 payments for more than seven days, as permitted by
            law.

Timing of   Redemption proceeds will normally be mailed to the redeeming
Redemption  shareholder within seven calendar days or, in the case of wire
Payments    transfer or Fund Link redemptions, sent to the designated bank
            account within one business day. Fund Link redemptions may be
            received by the bank on the second or third business day. In cases
            where shares have recently been purchased by personal check,
            redemption proceeds may be withheld until the check has been
            collected, which may take up to 15 days. To avoid such
            withholding, investors should purchase shares by certified or bank
            check or by wire transfer. Under unusual circumstances, the Trust
            may delay your redemption payments for more than seven days, as
            permitted by law.


Redemptions The Trust has 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 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.

Certifi-    If you are redeeming shares for which certificates have been
cated       issued, the certificates must be mailed to or deposited with the
Shares      Trust, duly endorsed or accompanied by a duly endorsed stock power
            or by a written request for redemption. Signatures must be
            guaranteed as described under "Signature Guarantee" below. The
            Trust may request further documentation from institutions or
            fiduciary accounts, such as corporations, custodians (e.g., under
            the Uniform Gifts to Minors Act), executors, administrators,

            must be signed exactly as the account is registered, including

            exchanges, registered securities associations and clearing
            agencies (each an "Eligible Guarantor Institution"). The
            Distributor reserves the right to reject any signature guarantee
            pursuant to its written signature guarantee standards or
            procedures, which may permit it to reject signature guarantees
            from Eligible Guarantor Institutions that do not, based on credit
            guidelines, satisfy such written standards or procedures.

             Beginning January 1, 2001, when a signature guarantee is called
            for, a "medallion" signature guarantee will be required. A
            medallion signature guarantee may be obtained from a domestic bank
            or trust company, broker, dealer, clearing agency, savings
            association or other financial institution which is participating
            in a medallion program recognized by the Securities Transfer
            Association. The three recognized medallion programs are the
            Securities Transfer Agents Medallion Program (STAMP), Stock
            Exchanges Medallion Program (SEMP) and New York Stock Exchange,
            Inc. Medallion Signature Program (NYSE MSP). Signature guarantees
            from financial institutions which are not participating in one of
            these programs will not be accepted. Please note that financial
            institutions participating in a recognized medallion program may
            still be ineligible to provide a signature guarantee for
            transactions of greater than a specified dollar amount. The Trust
            may change the signature guarantee requirements from time to time
            upon notice to shareholders, which may be given by means of a new
            or supplemented Prospectus or a new supplemented Guide.
            Shareholders should contact the Distributor for additional details
            regarding the Funds' signature guarantee requirements.

            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, but dividends on Class B and Class C shares are expected to
            be lower than dividends on Class A shares as a result of the
            distribution fees applicable to Class B and Class C shares. 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.

             You can choose from the following distribution options:

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

             . Invest all distributions in shares of the same class of any
               other Fund or another series of the Trust or PIMCO Funds:
               Pacific Investment Management Series which offers that class at
               NAV. You must have an account existing in the Fund or series
               selected for investment with the identical registered name. You
            must elect this option on your account application or by a
            telephone request to the Transfer Agent at 1-800-426-0107.

             . Receive all distributions in cash (either paid directly to you
               or credited to your account with your broker or other financial
               intermediary). You must elect this option on your account
            application or by a telephone request to the Transfer Agent at 1-
            800-426-0107.

             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.

             For further information on distribution options, please contact
            your broker or call the Distributor at 1-800-426-0107.

            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 them 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 generally 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.

             . A Note on the Tax-Efficient Equity Fund. The Tax-Efficient
            Equity Fund utilizes a number of tax-efficient management
            techniques designed to minimize taxable distributions. For
            instance, the Fund generally seeks to minimize realized gains and,
            when realizing gains, attempts to realize gains that will be taxed
            as capital gains (i.e., as gains on investments owned for more
            than 12 months) when distributed to shareholders. Although the
            Fund attempts to minimize taxable distributions, it may be
            expected to earn and distribute taxable income and realize and
            distribute capital gains from time to time.

             . A Note on Foreign Investments. A Fund's investment in foreign
            securities may be subject to foreign withholding taxes. In that
            case, the Fund's yield on those securities would be decreased. In
            addition, a Fund's investments in foreign securities or foreign
            currencies may increase or accelerate the Fund's recognition of
            ordinary income and may affect the timing or amount of the Fund's
            distributions. Shareholders of the Global Innovation,
            International and Allianz Select International Funds may be
            entitled to claim a credit or deduction with respect to foreign
            taxes.

             This section relates only to federal income tax consequences of
            investing in the Funds; the consequences under other tax laws may
            differ. You should consult your tax advisor as to the possible
            application of foreign, state and local income tax laws to Fund
            dividends and capital distributions. Please see the Statement of
            Additional Information for additional information regarding the
            tax aspects of investing in the Funds.

            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 identified
            under "Summary Information" above. It also describes
            characteristics and risks of additional securities and investment
            techniques that are not necessarily principal investments or
            strategies but may be used by the Funds from time to time. Most of
            these securities and investment techniques are discretionary,
            which means that the portfolio managers 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 must rely on the professional investment judgment and skill
            of PIMCO Advisors, the Sub-Advisers 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.
                                                                  Prospectus 54

Fixed       Fixed income securities are obligations of the issuer to make
Income      payments of principal and/or interest on future dates, and include
Securities  corporate and government bonds, notes, certificates of deposit,
and         commercial paper, convertible securities and mortgage-backed and
Defensive   other asset-backed securities.
Strategies

             The Capital Appreciation, Mid-Cap and Tax-Efficient Equity Funds
            intend to be as fully invested in common stocks as practicable at
            all times, although, for cash management purposes, each of these
            Funds may maintain a portion of its assets (normally not more than
            10%) in U.S. Government securities, high quality fixed income
            securities, money market obligations and cash to pay certain Fund
            expenses and to meet redemption requests. None of these Funds will
            make defensive investments in response to unfavorable market and
            other conditions and therefore may be particularly vulnerable to
            general declines in stock prices and/or other categories of
            securities in which they invest.

             Under normal circumstances, the Small-Cap Value Fund intends to
            be fully invested in common stocks (aside from cash management
            practices), except that the Fund may temporarily hold up to 10% of
            its assets in cash and cash equivalents for defensive purposes in
            response to unfavorable market and other conditions. The Equity
            Income, Global Innovation, Growth, Innovation, International,
            Opportunity, Renaissance, Select Growth, Allianz Select
            International, Target and Value Funds will each invest primarily
            in common stocks, and may also invest in other kinds of equity
            securities, including preferred stocks and securities (including
            fixed income securities and warrants) convertible into or
            exercisable for common stocks. Each of these Funds may invest a
            portion of its assets in fixed income securities. These Funds may
            temporarily hold up to 100% of their assets in short-term U.S.
            Government securities and other money market instruments for
            defensive purposes in response to unfavorable market and other
            conditions. The Growth & Income Fund will invest primarily in
            common stocks, but may also invest significant portions of its
            assets in preferred stocks, fixed income securities, convertible
            securities and real estate investment trusts, or "REITs." The
            Growth & Income Fund may temporarily hold up to 100% of its assets
            in short-term U.S. Government securities and other money market
            instruments for defensive purposes in response to unfavorable
            market and other conditions. The International and Allianz Select
            International Funds may also hold up to 100% of their assets in
            other domestic fixed income, foreign fixed income and equity
            securities principally traded in the U.S., including obligations
            issued or guaranteed by a foreign government or its agencies,
            authorities or instrumentalities, corporate bonds and American
            Depository Receipts, for temporary defensive purposes. The
            temporary defensive strategies described in this paragraph would
            be inconsistent with the investment objective and principal
            investment strategies of each of the noted Funds and may adversely
            affect the Fund's ability to achieve its investment objective.


Companies   Each of the Funds may invest in securities of companies with
With        market capitalizations that are small compared to other publicly
Smaller     traded companies. The Opportunity and Small-Cap Value Funds invest
Market      primarily in smaller companies and are especially sensitive to the
Capitali-   risks described below. In addition, the Global Innovation and
zations     Innovation Funds generally have substantial exposure to these
            risks. The Growth & Income, Mid-Cap, Allianz Select International
            and Target Funds also have significant exposure to these risks
            because they invest primarily in companies with medium-sized
            market capitalizations, which are smaller and generally less well-
            known or seasoned than the largest companies.

             Companies which are smaller and less well-known or seasoned than
            larger, more widely held companies may offer greater opportunities
            for capital appreciation, but may also involve risks different
            from, or greater than, risks normally associated with larger
            companies. Larger companies generally have greater financial
            resources, more extensive research and development, manufacturing,
            marketing and service capabilities, and more stability and greater
            depth of management and technical personnel than smaller
            companies. Smaller companies may have limited product lines,
            markets or financial resources or may depend on a small,
            inexperienced management group. Securities of smaller companies
            may trade less frequently and in lesser volume than more widely
            held securities and their values may fluctuate more abruptly or
            erratically than securities of larger companies. They may also
            trade in the over-the-counter market or on a regional exchange, or
            may otherwise have limited liquidity. These securities may
            therefore be more vulnerable to adverse market developments than
            securities of larger companies. Also, there may be less publicly
            available information about smaller companies or less market
            interest in their securities as compared to larger companies, and
            it may take longer for the prices of the securities to reflect the
            full value of a company's earnings potential or assets.

             Because securities of smaller companies may have limited
            liquidity, a Fund may have difficulty establishing or closing out
            its positions in smaller companies at prevailing market prices. As
            a result of owning large positions in this type of security, a
            Fund is subject to the additional risk of possibly having to sell
            portfolio securities at disadvantageous times and prices if
            redemptions require the Fund to liquidate its securities
            positions. For these reasons, it may be prudent for a Fund with a
            relatively large

55 PIMCO Funds: Multi-Manager Series
<PAGE>

            asset size to limit the number of relatively small positions it
            holds in securities having limited liquidity in order to minimize
            its exposure to such risks, to minimize transaction costs, and to
            maximize the benefits of research. As a consequence, as a Fund's
            asset size increases, the Fund may reduce its exposure to illiquid
            smaller capitalization securities, which could adversely affect
            performance.

Initial     The Funds, particularly the Global Innovation Fund, may purchase
Public      securities in initial public offerings (IPOs). These securities
Offerings   are subject to many of the same risks of investing in companies
            with smaller market capitalizations. Securities issued in IPOs
            have no trading history, and information about the companies may
            be available for very limited periods. In addition, the prices of
            securities sold in IPOs may be highly volatile. At any particular
            time or from time to time a Fund may not be able to invest in
            securities issued in IPOs, or invest to the extent desired,
            because, for example, only a small portion (if any) of the
            securities being offered in an IPO may be made available to the
            Fund. In addition, under certain market conditions fewer companies
            may issue securities in IPOs. Similarly, as the number of Funds to
            which IPO securities are allocated increases, the number of
            securities issued to any one Fund may decrease. The investment
            performance of a Fund during periods when it is unable to invest
            significantly or at all in IPOs may be lower than during periods
            when the Fund is able to do so. In addition, as a Fund increases
            in size, the impact of IPOs on the Fund's performance will
            generally decrease.


Foreign     The International and Allianz Select International Funds normally
(non-       invest principally in securities of foreign issuers, securities
U.S.)       traded principally in securities markets outside the United States
Securities  and/or securities denominated in foreign currencies (together,
            "foreign securities"). The Global Innovation Fund will invest in
            the securities of issuers located in at least three countries (one
            of which may be the United States). The Equity Income, Growth,
            Growth & Income, Innovation, Opportunity, Renaissance, Target and
            Value Funds may invest up to 15% of their respective assets in
            foreign securities. The Select Growth Fund may invest up to 25% of
            its assets in foreign securities. Each of these Funds may invest
            without limit in ADRs (defined below). The Tax-Efficient Equity
            Fund may invest in common stocks of foreign issuers if included in
            the S&P 500 Index.

             All of the Funds may invest in American Depository Receipts
            (ADRs). In addition, the Equity Income, Global Innovation, Growth,
            Growth & Income, Innovation, International, Opportunity,
            Renaissance, Select Growth, Allianz Select International, Target
            and Value Funds may invest in European Depository Receipts (EDRs)
            and Global Depository Receipts (GDRs). ADRs are dollar-denominated
            receipts issued generally by domestic banks and representing the
            deposit with the bank of a security of a foreign issuer, and are
            publicly traded on exchanges or over-the-counter in the United
            States. EDRs are receipts similar to ADRs and are issued and
            traded in Europe. GDRs may be offered privately in the United
            States and also traded in public or private markets in other
            countries.

             Investing in foreign securities involves special risks and
            considerations not typically associated with investing in U.S.
            securities and shareholders should consider carefully the
            substantial risks involved for Funds that invest in these
            securities. 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, rate
            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.


Emerging    Each of the Funds that may invest in foreign securities may invest
Market      in securities of issuers based in or that trade principally in
Securities  countries with developing (or "emerging market") economies. The
            Global Innovation, International and Allianz Select International
            Funds may invest significant portions of their assets in emerging
            market 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;
            and possible repatriation of investment income and capital. In
            addition, foreign investors may be required to register

                                                                   Prospectus 56

            the proceeds of sales, and future economic or political crises
            could lead to price controls, forced mergers, expropriation or
            confiscatory taxation, seizure, nationalization or the 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 market 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.

             Special Risks of Investing in Russian and Other Eastern European
            Securities. Each of the Global Innovation, International and
            Allianz Select International Funds may invest a significant
            portion of its assets in securities of issuers located in Russia
            and in other Eastern European countries. While investments in
            securities of such issuers are subject generally to the same risks
            associated with investments in other emerging market countries
            described above, the political, legal and operational risks of
            investing in Russian and other Eastern European issuers, and of
            having assets custodied within these countries, may be
            particularly acute. A risk of particular note with respect to
            direct investment in Russian securities is the way in which
            ownership of shares of companies is normally recorded. When a Fund
            invests in a Russian issuer, it will normally receive a "share
            extract," but that extract is not legally determinative of
            ownership. The official record of ownership of a company's share
            is maintained by the company's share registrar. Such share
            registrars are completely under the control of the issuer, and
            investors are provided with few legal rights against such
            registrars.

Foreign
Currencies  A Fund that invests directly in foreign currencies or in
            securities that trade in, and receive revenues in, foreign
            currencies will be subject to currency risk. The Global
            Innovation, International and Allianz Select International Funds
            are particularly sensitive to this risk.

             Foreign currency exchange rates may fluctuate significantly over
            short periods of time. They generally are determined by supply and
            demand 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, uncertainty
            surrounds the introduction of the euro (a common currency unit for
            the European Union) and the effect it may have on the value of
            European currencies as well as 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. The Equity Income, Global
            Innovation, Growth, Growth & Income, Innovation, International,
            Opportunity, Renaissance, Select Growth, Allianz Select
            International, Target and Value Funds may enter into forward
            foreign currency exchange contracts, primarily to reduce the risks
            of adverse changes in foreign exchange rates. In addition, the
            Global Innovation, International and Allianz Select International
            Funds may buy and sell foreign currency futures contracts and
            options on foreign currencies and foreign currency 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. Contracts to sell foreign currency would limit any
            potential gain which might be realized by a Fund if the value of
            the hedged currency increases. A Fund may enter into these
            contracts to hedge against foreign exchange risk arising from the
            Fund's investment or anticipated investment in securities
            denominated in foreign currencies. 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.

             The Global Innovation, International and Allianz Select
            International Funds may also enter into these contracts for
            purposes of increasing exposure to a foreign currency or to shift
            exposure to foreign currency fluctuations from one currency to
            another. To the extent that it does so, a Fund will be subject to
            the additional risk that the relative value of currencies will be
            different than anticipated by the Fund's portfolio manager. The
            Global Innovation, International and Allianz Select International
            Funds may use one currency (or basket of currencies) to hedge
            against adverse changes in the value of another currency (or
            basket of currencies) when exchange rates between the two
            currencies are positively correlated. Each Fund will segregate
            assets determined to be liquid by PIMCO Advisors or the Fund's
            Sub-Adviser 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.

Corporate
Debt        Each Fund that may invest in fixed income securities may invest in
Securities  corporate debt securities. The Growth & Income Fund may invest up
            to 10% of its assets in these securities. Corporate debt
            securities are subject to the risk of the issuer's inability to
            meet principal and interest payments on the obligation and may
            also be subject to price volatility due to factors such 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 durations tend to
            be more sensitive to interest rate movements than those with
            shorter durations.

Convertible Each Fund may invest in convertible securities. The Growth &
Securities  Income Fund may place particular emphasis on convertible
            securities. Convertible securities are generally preferred stocks
            and other securities, including fixed income securities and
            warrants, that are convertible into or exercisable for common
            stock at either a stated price or a stated 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. While
            convertible securities generally offer lower interest or dividend
            yields than non-convertible fixed income securities of similar
            quality, their value tends to increase as the market value of the
            underlying stock increases and to decrease when the value of the
            underlying stock decreases. Also, 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.

Derivatives
            Each Fund (except the Capital Appreciation, Mid-Cap and Small-Cap
            Value Funds) may, but is not required to, use a number of
            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. 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. In addition, 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.

             Examples of derivative instruments include options contracts,
            futures contracts, options on futures contracts and swap
            agreements. The Equity Income, Global Innovation, Growth, Growth &
            Income, Innovation, International, Opportunity, Renaissance,
            Select Growth, Allianz Select International, Target, Tax-Efficient
            Equity and Value Funds may purchase and sell (write) call and put
            options on securities, securities indexes and foreign currencies.
            Each of these Funds may purchase and sell futures contracts and
            options thereon with respect to securities, securities indexes and
            foreign currencies. The Global Innovation, Allianz Select
            International and Tax-Efficient Equity Funds may enter into swap
            agreements with respect to securities indexes. 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 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

                                                                   Prospectus 58
<PAGE>

            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.

             Leveraging 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 Advisors or a Sub-Adviser
            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 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
            (taxed at ordinary income tax rates when distributed to
            shareholders who are individuals) than if the Fund had not used
            such instruments.

Equity-
Linked      The Funds may invest in equity-linked securities. The Allianz
Securities  Select International Fund may invest up to 15% of its assets in
            equity-linked securities. The International Fund may invest up to
            5% of its assets in equity-linked securities. Equity-linked
            securities are privately issued securities whose investment
            results are designed to correspond generally to the performance of
            a specified stock index or "basket" of stocks, or sometimes a
            single stock. To the extent that the Fund invests in equity-linked
            securities whose return corresponds to the performance of a
            foreign securities index or one or more of foreign stocks,
            investing in equity-linked securities will involve risks similar
            to the risks of investing in foreign equity securities. See
            "Foreign Securities" above. In addition, the Fund bears the risk
            that the issuer of an equity-linked security may default on its
            obligations under the security. Equity-linked securities may be
            considered illiquid and thus subject to the Fund's restrictions on
            investments in illiquid securities.

Credit
Ratings
and
Unrated
Securities
            The Funds may invest in securities based on their credit ratings
            assigned by rating agencies such as Moody's Investors Service,
            Inc. ("Moody's") and Standard and Poor's Ratings Services ("S&P").
            Moody's, S&P and other rating agencies are private services that
            provide ratings of the credit quality of fixed income securities,
            including convertible securities. The Appendix to the Statement of
            Additional
59 PIMCO Funds: Multi-Manager Series
<PAGE>

            Information 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 risk. 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 Advisors and the Sub-
            Advisers do not rely solely on credit ratings, and develop their
            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.

High
Yield       Securities rated lower than Baa by Moody's or lower than BBB by
Securities  S&P are sometimes referred to as "high yield securities" or "junk
            bonds." The Funds, particularly the Growth & Income Fund, may
            invest in these securities. Investing in these 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,
            these securities may be subject to greater levels of interest
            rate, credit and liquidity risk, may entail greater potential
            price volatility and may be less liquid than higher-rated
            securities. These 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.

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 the party arranging the loan.

Short       Each Fund may make short sales as part of its overall portfolio
Sales       management strategies or to offset a potential decline in the
            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. A Fund may only enter into short selling transactions if
            the security sold short is held in the Fund's portfolio or if the
            Fund has the right to acquire the security without the payment of
            further consideration. 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.

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
Transactionssettlement date. This risk is in addition to the risk that the
            Fund's other assets will decline in 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
Agreements
            Each Fund may enter into repurchase agreements, in which the Fund
            purchases a security from a bank or broker-dealer that 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. Those Funds whose investment objectives do not
            include the earning of income will invest in repurchase agreements
            only as a cash management technique with respect to that portion
            of its portfolio maintained in cash. Repurchase agreements
            maturing in more than seven days are considered illiquid
            securities.
                                                                  Prospectus 60

Reverse     Each Fund may enter into reverse repurchase agreements, subject to
Repurchase  the Fund's limitations on borrowings. A reverse repurchase
Agreements  agreement involves the sale of a security by a Fund and its
And Other   agreement to repurchase the instrument at a specified time and
Borrowings  price, and may be considered a form of borrowing for some
            purposes. A Fund will segregate assets determined to be liquid by
            PIMCO Advisors or a Sub-Adviser in accordance with procedures
            established by the Board of Trustees to cover its obligations
            under reverse repurchase agreements. 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 and other
            forms of borrowings may create leveraging risk for a Fund.

Illiquid    Each Fund may invest in securities that are illiquid so long as
Securities  not more than 15% of the value of the Fund's net assets (taken at
            market value at the time of investment) would be invested in such
            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 held by a
            Fund, 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. Please see "Investment Objectives and Policies" in
            the Statement of Additional Information for a listing of various
            securities that are generally considered to be illiquid for these
            purposes. 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  The International and Allianz Select International Funds may
in other    invest up to 10% of their assets in securities of other investment
Investment  companies, such as closed-end management investment companies, or
Companies   in pooled accounts or other investment vehicles which invest in
            foreign markets. Each of the other Funds may invest up to 5% of
            its assets in other investment companies. 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.

Portfolio
Turnover    With the exception of the Tax-Efficient Equity Fund, the length of
            time a Fund has held a particular security is not 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 active and frequent trading of portfolio securities to
            achieve its investment objective and principal investment
            strategies, particularly during periods of volatile market
            movements, although the Tax-Efficient Equity Fund will generally
            attempt to limit portfolio turnover as part of its tax-efficient
            management strategies. 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 taxed
            at ordinary income tax rates when distributed to shareholders who
            are individuals). The trading costs and tax effects associated
            with portfolio turnover may adversely affect a Fund's performance.
            Funds, such as the Growth & Income, Select Growth and Allianz
            Select International Funds, that have recently changed Sub-
            Advisers and/or investment objectives and policies may experience
            increased portfolio turnover due to the differences between the
            Funds' previous and current investment objectives and policies and
            portfolio management strategies.

Changes
in          The investment objective of each of the Global Innovation, Growth,
Investment  Growth & Income, Innovation, International, Opportunity,
Objectives  Renaissance, Select Growth, Allianz Select International, Target
and         and Tax-Efficient Equity Funds described in this Prospectus may be
Policies    changed by the Board of Trustees without shareholder approval. The
            investment objective of each other Fund is fundamental and may not
            be changed without shareholder approval. Unless otherwise stated
            in the Statement of Additional Information, all investment
            policies of the Funds may be changed by the Board of Trustees
            without shareholder approval. If there is a change in a Fund's
            investment objective or policies, including a change approved by
            shareholder vote, shareholders should consider whether the Fund
            remains an appropriate investment in light of their then current
            financial position and needs.

New and
Smaller-    In addition to the risks described under "Summary of Principal
Sized       Risks" above and in this section, several of the Funds are newly
Funds       formed and therefore have limited or no performance history for
            investors to evaluate. Also, it is possible that newer Funds and
            smaller-sized Funds may invest in securities offered in initial
            public offerings and other types of transactions (such as private
            placements) which, because of the Funds' size, may have a
            disproportionate impact on the Funds' performance results. The
            Funds would not necessarily have achieved the same performance
            results if their aggregate net assets had been greater.

Percentage  Unless otherwise stated, all percentage limitations on Fund
Investment  investments listed in this Prospectus will apply at the time of
Limitations investment. A Fund would not violate these limitations unless an
            excess or deficiency occurs or exists immediately after and as a
            result of an investment.

            Financial Highlights

            The financial highlights table is intended to help you understand
            the financial performance of Class A, Class B and Class C shares
            of each Fund for the past 5 years or, if the class is less than 5
            years old, since the class of shares was first offered. Certain
            information reflects financial results for a single Fund share.
            The total returns in the table represent the rate that an investor
            would have earned or lost on an investment in a particular class
            of shares of a Fund, assuming reinvestment of all dividends and
            distributions. This information has been audited by
            PricewaterhouseCoopers LLP, whose report, along with each Fund's
            financial statements, are included in the Trust's annual report to
            shareholders. The annual report is incorporated by reference in
            the Statement of Additional Information and is available free of
            charge upon request from the Distributor.

             The information provided for each of the Growth, Innovation,
            International, Opportunity, Renaissance and Target Funds reflects
            the operational history of a corresponding series of PIMCO
            Advisors Funds which reorganized as a series of the Trust on
            January 17, 1997. In connection with the reorganizations, these
            Funds changed their fiscal year ends from September 30 to June 30.
            The expense ratios provided for these Funds for periods prior to
            January 17, 1997 reflect fee arrangements of PIMCO Advisors Funds
            previously in effect which differ from the current fee
            arrangements of the Trust. The Growth & Income and Allianz Select
            International Funds did not offer Class A, B or C shares during
            the periods ended June 30, 2000.

             It is possible to lose money on investments in the Funds. The
             fact that a Fund had good performance in the past (for example,
             during the year ended 1999) is no assurance that the value of the
             Fund's investments will not decline in the future or appreciate
             at a slower rate. 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.

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of companies
            with larger market capitalizations that have improving
            fundamentals (based on growth criteria) and whose stock is
            reasonably valued by the market (based on value criteria).

             In making investment decisions for the Fund, the portfolio
            management team considers the 1,000 largest publicly traded
            companies (in terms of market capitalization) in the U.S. The team
            screens the stocks in this universe for a series of growth
            criteria, such as dividend growth, earnings growth, relative
            growth of earnings over time (earnings momentum) and the company's
            history of meeting earnings targets (earnings surprise), and also
            value criteria, such as price-to-earnings, price-to-book and
            price-to-cash flow ratios. The team then selects individual stocks
            by subjecting the top 10% of the stocks in the screened universe
            to a rigorous analyses of company factors, such as strength of
            management, competitive industry position, and business prospects,
            and financial statement data, such as earnings, cash flows and
            profitability. The team may interview company management in making
            investment decisions. The Fund's capitalization criteria applies
            at the time of investment.

             The portfolio management team rescreens the universe frequently
            and seeks to consistently achieve a favorable balance of growth
            and value characteristics for the Fund. The team looks to sell a
            stock when it falls below the median ranking, has negative
            earnings surprises, or shows poor price performance relative to
            all stocks in the Fund's capitalization range or to companies in
            the same business sector. A stock may also be sold if its
            weighting in the portfolio becomes excessive (normally above 2% of
            the Fund's investments).

             The Fund intends to be fully invested in common stock (aside from
            certain cash management practices) and will not make defensive
            investments in response to unfavorable market and other
            conditions.

                "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 its not reflected under Distribution
                and/or Service (12b-1) Fees and 0.01% in other expenses
                attributable to the class during the most recent fiscal year.

            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 Class D 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 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.

</TABLE>

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in income-producing (e.g.,
            dividend-paying) common stocks of companies with market
            capitalizations of more than $2 billion at the time of investment.
            The Fund may also invest to a limited degree in convertible
            securities and preferred stocks.

             The Fund's initial selection universe consists of the 1,000
            largest publicly traded companies (in terms of market
            capitalization) in the U.S. The portfolio managers classify the
            universe by industry. They then identify the most undervalued
            stocks in each industry based mainly on relative P/E ratios,
            calculated both with respect to trailing operating earnings and
            forward earnings estimates. From this group of stocks, the Fund
            buys approximately 25 stocks with the highest dividend yields. The
            portfolio managers then screen the most undervalued companies in
            each industry by dividend yield to identify the highest yielding
            stocks in each industry. From this group, the Fund buys
            approximately 25 additional stocks with the lowest P/E ratios.

             In selecting stocks, the portfolio managers consider quantitative
            factors such as price momentum (based on changes in stock price
            relative to changes in overall market prices), earnings momentum
            (based on analysts' earnings per share estimates and revisions to
            those estimates), relative dividend yields, valuation relative to
            the overall market and trading liquidity. The portfolio managers
            may replace a stock when a stock within the same industry group
            has a considerably higher dividend yield or lower valuation than
            the Fund's current holding.

             The Fund may invest up to 15% of its assets in foreign
            securities, except that it may invest without limit in American
            Depository Receipts (ADRs). In response to unfavorable market and
            other conditions, the Fund may make temporary investments of some
            or all of its assets in high-quality fixed income securities. This
            would be inconsistent with the Fund's investment objective and
            principal strategies.

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

              .Market Risk           .Foreign              .Credit Risk
              .Issuer Risk           Investment Risk       .Management
              .Value Securities      .Currency Risk        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. For periods prior to the inception of the
            Fund's Class D shares (4/8/98), performance information shown in
            the bar chart (including the information to its right) and the
            Average Annual Total Returns table is based on the performance of
            the Fund's Institutional Class shares, which are offered in a
            different prospectus. The prior Institutional Class performance
            has been adjusted to reflect the actual distribution and/or
            service (12b-1) fees and other expenses paid by Class D shares.
            Prior to May 8, 2000, the Fund had a different sub-adviser and
            would not necessarily have achieved the performance results shown
            on the next page under its current investment management
            arrangements. 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
                Administrative Fee 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--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.

                attributable to the class during the most recent fiscal year.

            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

            Examples also assume that your investment has a 5% return each
            year, the reinvestment of all dividends and distributions, and 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.

 </TABLE>
            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of U.S. and
            non-U.S. companies which utilize new, creative or different, or
            "innovative," technologies to gain a strategic competitive
            advantage in their industry, as well as companies that provide and
            service those technologies. The Fund identifies its investment
            universe of technology-related companies primarily by reference to
            classifications made by independent firms, such as Standard &
            Poor's (for example, companies classified as "Information
            Technology" companies), and by identifying companies that derive a
            substantial portion of their revenues from the manufacture, sale
            and/or service of technological products. Although the Fund
            emphasizes companies which utilize technologies, it is not
            required to invest exclusively in a particular business sector or
            industry.

              The portfolio manager selects stocks for the Fund using a
            "growth" style. The portfolio manager seeks to identify
            technology-related companies with well-defined "wealth creating"
            characteristics, including superior earnings growth (relative to
            companies in the same industry or the market as a whole), high
            profitability and consistent, predictable earnings. In addition,
            through fundamental research, the portfolio manager seeks to
            identify companies that are gaining market share, have superior
            management and possess a sustainable competitive advantage, such
            as superior or innovative products, personnel and distribution
            systems. The Fund looks to sell a stock when the portfolio manager
            believes that earnings or market sentiment are disappointing, if
            the company does not meet or exceed consensus estimates on
            revenues and/or earnings or if an alternative investment is more
            attractive.

              Although the Fund invests principally in common stocks, the Fund
            may also invest in other types of equity securities, including
            preferred stocks and convertible securities. The Fund may invest a
            substantial portion of its assets in the securities of smaller
            capitalization companies and securities issued in initial public
            offerings (IPOs). The Fund will invest in the securities of
            issuers located in at least three countries (one of which may be
            the United States). Although the Fund invests primarily in
            securities traded principally in the securities markets of
            developed countries, the Fund has no other prescribed limits on
            geographic asset distribution and may invest in any foreign
            securities market in the world, including in developing, or
            "emerging," markets. The Fund may utilize foreign currency
            exchange contracts and derivative instruments (such as stock index
            futures contracts), primarily for risk management or hedging
            purposes.

              In response to unfavorable market and other conditions, the Fund
            may make temporary investments of some or all of its assets in
            high-quality fixed income securities. This would be inconsistent
            with the Fund's investment objective and principal strategies.

</TABLE>
            (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
                 Administrative Fee paid under the administration agreement
                 may be Distribution and/or Service (12b-1) Fees. The Fund
                 will pay a total of 0.85% 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--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, and 0.09% in organizational
                 expenses ("Organizational Expenses") attributable to the
                 class during the most recent fiscal year.

            (3)  Net Expenses reflect the effect of a contractual agreement by
                 PIMCO Advisors to waive, reduce or reimburse its
                 Administrative Fees for each class in an amount that, in
                 essence, is equal to the Fund's Organizational Expenses
                 attributed to the class. Because the Organizational Expenses
                 were accounted for in the Fund's initial fiscal year, the
                 Fund's reasonable expectation is that the relevant conditions
                 will not continue after the Fund's fiscal year ending June
                 30, 2000.

            Examples. The Examples below 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 Class D 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 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.

</TABLE>
            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of "growth"
            companies with market capitalizations of at least $5 billion at
            the time of investment.

             The portfolio manager selects stocks for the Fund using a
            "growth" style. The portfolio manager seeks to identify companies
            with well-defined "wealth creating" characteristics, including
            superior earnings growth (relative to companies in the same
            industry or the market as a whole), high profitability and
            consistent, predictable earnings. In addition, through fundamental
            research, the portfolio manager seeks to identify companies that
            are gaining market share, have superior management and possess a
            sustainable competitive advantage, such as superior or innovative
            products, personnel and distribution systems. The Fund looks to
            sell a stock when the portfolio manager believes that its
            earnings, market sentiment or relative performance are
            disappointing or if an alternative investment is more attractive.

             The Fund may also invest to a limited degree in other kinds of
            equity securities, including preferred stocks and convertible
            securities. The Fund may invest up to 15% of its assets in foreign
            securities, except that it may invest without limit in American
            Depository Receipts (ADRs). The Fund has in the past invested a
            significant portion of its assets in technology or technology-
            related companies, although there is no assurance that it will
            continue to do so in the future.

             In response to unfavorable market and other conditions, the Fund
            may make temporary investments of some or all of its assets in
            high-quality fixed income securities. This would be inconsistent
            with the Fund's investment objective and principal strategies.

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 Class C shares, which are offered in a different
            prospectus. This is because the Fund has not had Class D shares
            outstanding for a full calendar year. Although Class D and Class C
            shares would have similar annual returns (because all of the
            Fund's shares represent interests in the same portfolio of
            securities), Class D performance would be higher than Class C
            performance because of the lower expenses paid by Class D shares.
            The Class C performance in the bar chart and the information to
            its right do not reflect the impact of sales charges (loads). If
            they did, the returns would be lower than those shown. Unlike the
            bar chart, performance figures for Class C shares in the Average
            Annual Total Returns table reflect the impact of sales charges.

             For periods prior to the inception of Class D shares (11/1/99),
            the Average Annual Total Returns table also shows estimated
            historical performance for Class D shares based on the performance
            of Class C shares, adjusted to reflect that there are no sales
            charges and lower distribution and/or service (12b-1) fees paid by
            Class D shares. Prior to March 6, 1999, the Fund had a different
            sub-adviser and would not necessarily have achieved the
            performance results shown on the next page under its current
            investment management arrangements. 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
                Administrative Fee paid under the administration agreement may
                be Distribution and/or Service (12b-1) Fees. The Fund will pay

                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 and 0.01% in other expenses
                attributable to the class during the most recent fiscal year.

            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 Class D 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 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.

                                   40-60

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in securities of companies
            with market capitalizations of at least $1 billion at the time of
            investment. The Fund may invest up to 75% of its assets in
            securities selected for their growth potential. The Fund will
            normally invest at least 25% of its assets in securities selected
            for their income potential, including dividend-paying common
            stocks, preferred stocks, corporate bonds, convertible securities
            and real estate investment trusts (REITs).

             When selecting securities for the Fund's "growth" segment, the
            portfolio managers seek to identify companies with well-defined
            "wealth creating" characteristics, including superior earnings
            growth (relative to companies in the same industry or the market
            as a whole), high profitability and consistent, predictable
            earnings. In addition, through fundamental research, the portfolio
            managers seek to identify companies that are gaining market share,
            have superior management and possess a sustainable competitive
            advantage, such as superior or innovative products, personnel and
            distribution systems. The Fund's portfolio managers may choose to
            sell a stock in the "growth" segment when they believe that its
            earnings will be disappointing or that market sentiment on the
            company will turn negative. The portfolio managers will also
            consider selling a stock if the company does not meet the
            managers' estimates on revenues and/or earnings, or if an
            alternative investment is deemed to be more attractive.

             When selecting securities for the Fund's "income" segment, the
            portfolio managers seek to identify companies with strong
            operating fundamentals that offer potential for capital
            appreciation and that also have a dividend yield in excess of the
            yield on the S&P 500 Index. The portfolio managers may replace an
            "income" security when another security with a similar risk-to-
            reward profile offers either better potential for capital
            appreciation or a higher yield than the Fund's current holding. To
            achieve its income objective, the Fund may also invest to a
            limited degree in preferred stocks, convertible securities and
            REITs. The Fund may invest up to 10% of its assets in corporate
            bonds, which will typically consist of investment grade securities
            of varying maturities but may also include high yield securities
            ("junk bonds") rated at least B by Standard & Poor's Rating
            Services or Moody's Investors Service, Inc. or, if unrated,
            determined by the Adviser to be of comparable quality.

             The Fund may invest up to 15% of its assets in foreign
            securities, except that it may invest without limit in American
            Depository Receipts (ADRs). The Fund has in the past invested a
            significant portion of its assets in technology or technology-
            related companies, although there is no assurance that it will
            continue to do so in the future. In response to unfavorable market
            and other conditions, the Fund may make temporary investments of
            some or all of its assets in high-quality fixed income securities.
            This would be inconsistent with the Fund's investment objective
            and principal strategies.

Performance
Information The following shows summary performance 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 and the information to its right
            show performance of the Fund's Institutional Class shares, which
            are offered in a different prospectus. This is because the Fund
            did not offer Class D shares during the periods shown. 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 based on the performance of the Fund's Institutional Class
            shares, adjusted to reflect the actual distribution and/or service
            (12b-1) fees and other expenses paid by Class D shares. The
            performance information for periods prior to August 1, 2000
            reflects the Fund's advisory fee rate in

            effect prior to that date (0.63% per annum), which is higher than
            the current rate (0.60% per annum). Prior to July 1, 1999, the
            Fund had a different sub-adviser and would not necessarily have
            achieved the performance results shown under its current
            investment management arrangements. In addition, the Fund changed
            its investment objective and policies on August 1, 2000; the
            performance results shown on the next page would not necessarily
            have been achieved had the Fund's current objective and policies
            then been in effect. Past performance is no guarantee of future
            results.

            (2)  The Lipper Large-Cap Core Funds Average is a total return
                 performance average of funds tracked by Lipper Analytical
                 Services, Inc. that invest primarily in companies with market
                 capitalizations of greater than 300% of the dollar-weighted
                 median market capitalization of the S&P Mid-Cap 400 Index. It
                 does not take into account sales charges. The Lipper Large-Cap

</TABLE>
            (1) On August 1, 2000, the Fund's advisory fee rate decreased by
                0.03% to 0.60% per annum.
            (2) 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
                Administrative Fee paid under the administration agreement may
                be Distribution and/or Service (12b-1) Fees. The Fund will pay
                a total of 0.75% 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--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.

            (3) 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 and 0.15% in other expenses
                estimated to be attributable to the class during the current
                fiscal year.
              Examples. The Examples below 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 Class D 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 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.

  </TABLE>

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of companies
            which utilize new, creative or different, or "innovative,"
            technologies to gain a strategic competitive advantage in their
            industry, as well as companies that provide and service those
            technologies. The Fund identifies its investment universe of
            technology-related companies primarily by reference to
            classifications made by independent firms, such as Standard &
            Poor's (for example, companies classified as "Information
            Technology" companies), and by identifying companies that derive a
            substantial portion of their revenues from the manufacture, sale
            and or/service of technological products. Although the Fund
            emphasizes companies which utilize technologies, it is not
            required to invest exclusively in companies in a particular
            business sector or industry.

             The portfolio manager selects stocks for the Fund using a
            "growth" style. The portfolio manager seeks to identify
            technology-related companies with well-defined "wealth creating"
            characteristics, including superior earnings growth (relative to
            companies in the same industry or the market as a whole), high
            profitability and consistent, predictable earnings. In addition,
            through fundamental research, the portfolio manager seeks to
            identify companies that are gaining market share, have superior
            management and possess a sustainable competitive advantage, such
            as superior or innovative products, personnel and distribution
            systems. The Fund looks to sell a stock when the portfolio manager
            believes that earnings or market sentiment are disappointing, if
            the company does not meet or exceed consensus estimates on
            revenues and/or earnings or if an alternative investment is more
            attractive.

             Although the Fund invests principally in common stocks, the Fund
            may also invest in other kinds of equity securities, including
            preferred stocks and convertible securities. The Fund may invest a
            substantial portion of its assets in the securities of smaller
            capitalization companies. The Fund may invest up to 15% of its
            assets in foreign securities, except that it may invest without
            limit in American Depository Receipts (ADRs). In response to
            unfavorable market and other conditions, the Fund may make
            temporary investments of some or all of its assets in high-quality
            fixed income securities. This would be inconsistent with the
            Fund's investment objective and principal strategies.

            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. For periods prior to the inception of the
            Fund's Class D shares (4/8/98), performance information shown in
            the bar chart (including the information to its right) and the
            Average Annual Total Returns table show performance of the Fund's
            Class A shares, which are offered in a different prospectus. The
            prior Class A performance has been adjusted to reflect that there
            are no sales charges (loads) paid by Class D shares. Prior to
            March 6, 1999, the Fund had a different sub-adviser and would not
            necessarily have achieved the performance results shown on the
            next page under its current investment management arrangements.

            (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
                Administrative 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--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 Class D 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 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.

</TABLE>


            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of companies
            with medium market capitalizations that have improving
            fundamentals (based on growth criteria) and whose stock is
            reasonably valued by the market (based on value criteria).

             In making investment decisions for the Fund, the portfolio
            management team considers companies in the U.S. market with market
            capitalizations of more than $500 million, but excluding the 200
            largest capitalization companies. The team screens the stocks in
            this universe for a series of growth criteria, such as dividend
            growth, earnings growth, relative growth of earnings over time
            (earnings momentum) and the company's history of meeting earnings
            targets (earnings surprise), and also value criteria, such as
            price-to-earnings, price-to-book and price-to-cash flow ratios.
            The team then selects individual stocks by subjecting the top 10%
            of the stocks in the screened universe to a rigorous analyses of
            company factors, such as strength of management, competitive
            industry position, and business prospects, and financial statement
            data, such as earnings, cash flows and profitability. The team may
            interview company management in making investment decisions. The
            Fund's capitalization criteria applies at the time of investment.

             The portfolio management team rescreens the universe frequently
            and seeks to consistently achieve a favorable balance of growth
            and value characteristics for the Fund. The team looks to sell a
            stock when it falls below the median ranking, has negative
            earnings surprises, or shows poor price performance relative to
            all stocks in the Fund's capitalization range or to companies in
            the same business sector. A stock may also be sold if its
            weighting in the portfolio becomes excessive (normally above 2% of
            the Fund's investments).

             The Fund intends to be fully invested in common stock (aside from
            certain cash management practices) and will not make defensive
            investments in response to unfavorable market and other
            conditions.

            (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
                Administrative 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--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 and 0.01% in other expenses
                attributable to the class during the most recent fiscal year.

            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 Class D 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 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.

</TABLE>

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of companies
            with below-average valuations whose business fundamentals are
            expected to improve. Although the Fund typically invests in
            companies with market capitalizations of $1 billion to $10 billion
            at the time of investment, it may invest in companies in any
            capitalization range. To achieve income, the Fund invests a
            portion of its assets in income-producing (e.g., dividend-paying)
            stocks.

             The portfolio manager selects stocks for the Fund using a "value"
            style. The portfolio manager invests primarily in common stocks of
            companies having below-average valuations whose business
            fundamentals, such as market share, strength of management and
            competitive position, are expected to improve. The portfolio
            manager determines valuation based on characteristics such as
            price-to-earnings, price-to-book, and price-to-cash flow ratios.
            The portfolio manager analyzes stocks and seeks to identify the
            key drivers of financial results and catalysts for change, such as
            new management and new or improved products, that indicate a
            company may demonstrate improving fundamentals in the future. The
            portfolio manager looks to sell a stock when he believes that the
            company's business fundamentals are weakening or when the stock's
            valuation has become excessive.

             The Fund may also invest to a limited degree in other kinds of
            equity securities, including preferred stocks and convertible
            securities. The Fund may invest up to 15% of its assets in foreign
            securities, except that it may invest without limit in American
            Depository Receipts (ADRs).

             In response to unfavorable market and other conditions, the Fund
            may make temporary investments of some or all of its assets in
            high-quality fixed income securities. This would be inconsistent
            with the Fund's investment objective and principal strategies.

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

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

                                                            .Credit Risk
              .Issuer Risk           .Currency Risk         .Management 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. For periods prior to the inception of the
            Fund's Class D shares (4/8/98), performance information shown in
            the bar chart (including the information to its right) and the
            Average Annual Total Returns table show performance of the Fund's
            Class C shares, which are offered in a different prospectus. The
            prior Class C performance has been adjusted to reflect that there
            are no sales charges (loads) and lower distribution and/or service
            (12b-1) fees paid by Class D shares. Prior to March 6, 1999, the
            Fund had a different sub-adviser and would not necessarily have
            achieved the performance results shown on the next page under its
            current investment management arrangements. Past performance is no
            guarantee of future results.

             The Average Annual Total Returns table also shows estimated
            historical performance for Class D shares. Prior to the inception
            of Class D shares (4/8/98), the performance is based on the
            performance of the Fund's Class C shares, adjusted to reflect that
            there are no sales charges and lower distribution and/or service
            (12b-1) fees paid by Class D shares. Prior to May 7, 1999, the
            Fund had a different sub-adviser and would not necessarily have
            achieved the performance results shown on the next page under its
            current investment management arrangements. Past performance is no
            guarantee of future results.

</TABLE>

            (1) The Russell Mid-Cap Value Index is an unmanaged index that
                measures the performance of medium capitalization companies in
                the Russell 1000 Index with lower price-to-book ratios and
                lower forecasted growth values. It is not possible to invest
                directly in the index. The Mid-Cap Value Index replaced the
                Russell 1000 Value Index (an unmanaged index that measures the
                performance of companies in the Russell 1000 Index considered
                to have less than average growth orientation) and the S&P 500
                Index (an unmanaged index of large capitalization common
                stocks) as one of the Fund's comparative indexes because PIMCO
                Advisors believes the Russell Mid-Cap Value Index is more
                representative of the Fund's investment strategies. For
                periods ended December 31, 1999, the 1 Year, 5 Years, 10 Years

            (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
                Administrative Fee 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-- 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

            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 Class D 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 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.

</TABLE>

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of "growth"
            companies with market capitalizations of at least $10 billion at
            the time of investment. The Fund normally invests in the
            securities of 15 to 25 issuers.

             The portfolio manager selects stocks for the Fund using a
            "growth" style. The portfolio manager seeks to identify companies
            with well-defined "wealth creating" characteristics, including
            superior earnings growth (relative to companies in the same
            industry or the market as a whole), high profitability and
            consistent, predictable earnings. In addition, through fundamental
            research, the portfolio manager seeks to identify companies that
            are gaining market share, have superior management and possess a
            sustainable competitive advantage, such as superior or innovative
            products, personnel and distribution systems. The Fund looks to
            sell a stock when the portfolio manager believes that its
            earnings, market sentiment or relative performance are
            disappointing or if an alternative investment is more attractive.
            The Fund is "non-diversified," which means that it invests in a
            relatively small number of issuers.

             The Fund may also invest to a limited degree in other kinds of
            equity securities, including preferred stocks and convertible
            securities. The Fund may invest up to 25% of its assets in foreign
            securities, except that it may invest without limit in American
            Depository Receipts (ADRs). The Fund has in the past invested a
            significant portion of its assets in technology or technology-
            related companies, although there is no assurance that it will
            continue to do so in the future. In response to unfavorable market
            and other conditions, the Fund may make temporary investments of
            some or all of its assets in high-quality fixed income securities.
            This would be inconsistent with the Fund's investment objective
            and principal strategies.

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

                .Market Risk        .Focused Investment Risk  .Currency Risk
                .Issuer Risk        .Growth Securities Risk   .Credit Risk
                .Technology Related .Foreign Investment Risk  .Management Risk
                 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 did not offer Class
            D shares during the periods shown. 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 estimated Class D
            performance is based on the performance of the Fund's
            Institutional Class shares, adjusted to reflect the actual
            distribution and/or service (12b-1) fees and other expenses paid
            by Class D shares.

            The performance information on the next page for periods prior to
            April 1, 2000 reflects the Fund's advisory fee rate in effect
            prior to that date (0.57% per annum); these results would have
            been lower had the Fund's current advisory fee rate (0.60% per
            annum) then been in effect. Prior to July 1, 1999, the Fund had a
            different sub-adviser and would not necessarily have achieved the
            performance results shown on the next page under its current
            investment management arrangements. In addition, the Fund changed
            its investment objective and policies on April 1, 2000; the
            performance results shown on the next page would not necessarily
            have been achieved had the Fund's current objective and policies
            then been in effect. Past performance is no guarantee of future
            results.

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in an international portfolio
            of common stocks and other equity securities of companies located
            outside of the United States. Although the Fund normally invests
            in issuers from at least five different countries, it may at times
            invest in fewer than five countries, or even a single country. The
            Fund typically invests in approximately 30 to 60 stocks. Although
            the Fund invests primarily in developed market countries, it may
            also invest in developing, or "emerging," markets. The Fund has no
            other limits on geographic asset distribution and may invest in
            any foreign securities market in the world. The Fund may also
            invest in securities of foreign issuers traded on U.S. securities
            markets, but will normally not invest in U.S. issuers. The Fund
            invests most of its assets in foreign securities which trade in
            currencies other than the U.S. dollar and may invest directly in
            foreign currencies.

             The portfolio manager selects securities for the Fund using a
            research-driven "bottom-up" approach that seeks to utilize the
            Sub-Adviser's global research capabilities to identify companies
            with above-average long-term growth prospects and attractive
            valuations and that possess a sustainable competitive advantage,
            such as superior or innovative products, personnel and
            distribution systems. The portfolio manager seeks to select those
            stocks with the best long-term performance expectations, using a
            broad range of company fundamentals, such as long-term growth
            prospects, price-to-earnings ratios and other valuation measures,
            dividend and profit growth, balance sheet strength and return on
            assets. The portfolio managers sell stocks in order to adjust or
            rebalance the Fund's portfolio and to replace companies with
            weakening fundamentals.

             The Fund may invest a portion of its assets in the securities of
            small and medium capitalization companies. The Fund may utilize
            foreign currency exchange contracts and derivative instruments
            (such as stock index futures contracts), primarily for portfolio
            management and hedging purposes. The Fund may to a limited degree
            invest in equity securities other than common stocks (such as
            equity-linked securities, preferred stocks and convertible
            securities) and may invest up to 10% of its assets in other
            investment companies. In response to unfavorable market and other
            conditions, the Funds may make temporary investments of some or
            all of its assets in foreign and domestic fixed income securities
            and in equity securities of U.S. issuers. This would be
            inconsistent with the Fund's investment objective and principal
            strategies.

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 shows performance
            of the Fund's Institutional Class shares, which are offered in a
            different prospectus. This is because the Fund did not offer Class
            D shares during the periods shown. 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 estimated Class D
            performance is based on performance of the Fund's Institutional
            Class shares, adjusted to reflect the actual distribution and/or
            service (12b-1) fees and other expenses paid by Class D shares.

            The performance information for periods prior to May 8, 2000
            reflects the Fund's advisory fee rate in effect prior to that date
            (0.85% per annum), which is lower than the current rate (0.75% per
            annum). Prior to November 1, 2000, the Fund had different sub-
            advisers and would not necessarily have achieved the performance
            results shown on the next page under its current investment
            management arrangements. In addition, the Fund changed its
            investment objective and policies on November 1, 2000; the
            performance results shown on the next page would not necessarily
            have been achieved had the Fund's current objective and policies
            then been in effect. Past performance is no guarantee of future
            results.

                0.10%, to 0.75% per annum.
            (2) 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
                Administrative Fee paid under the administration agreement may
                be Distribution and/or Service (12b-1) Fees. The Fund will pay
                a total of 0.95% 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--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.
            (3) Other Expenses reflects the portion of the Administrative Fee
                paid by the class that its 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 Class D 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 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.

</TABLE>
            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of "growth"
            companies with market capitalizations of between $1 billion and
            $10 billion at the time of investment.

             The portfolio managers select stocks for the Fund using a
            "growth" style. The portfolio managers seek to identify companies
            with well-defined "wealth creating" characteristics, including
            superior earnings growth (relative to companies in the same
            industry or the market as a whole), high profitability and
            consistent, predictable earnings. In addition, through fundamental
            research, the portfolio managers seek to identify companies that
            are gaining market share, have superior management and possess a
            sustainable competitive advantage, such as superior or innovative
            products, personnel and distribution systems. The Fund looks to
            sell a stock when the portfolio managers believe that its
            earnings, market sentiment or relative performance are
            disappointing or if an alternative investment is more attractive.

             The Fund may also invest to a limited degree in other kinds of
            equity securities, including preferred stocks and convertible
            securities. The Fund may invest up to 15% of its assets in foreign
            securities, except that it may invest without limit in American
            Depository Receipts (ADRs). The Fund has in the past invested a
            significant portion of its assets in technology or technology-
            related companies, although there is no assurance that it will
            continue to do so in the future.

             In response to unfavorable market and other conditions, the Fund
            may make temporary investments of some or all of its assets in
            high-quality fixed income securities. This would be inconsistent
            with the Fund's investment objective and principal strategies.

            would have similar annual returns (because all of the Fund's
            shares represent interests in the same portfolio of securities),
            Class D performance would be higher than Class A performance
            because Class D shares do not pay any sales charges (loads). The
            Class A performance in the bar chart and the information to its
            right do not reflect the impact of sales charges. If they did, the
            returns would be lower than those shown. Unlike the bar chart,
            performance for Class A shares in the Average Annual Total Returns
            table reflects the impact of sales charges.

            The Average Annual Total Returns table also shows estimated
            historical performance for Class D shares based on the performance
            of the Fund's Class A shares, adjusted to reflect that there are
            no sales charges paid by Class D shares. Prior to March 6, 1999,
            the Fund had a different sub-adviser and would not necessarily
            have achieved the performance results shown on the next page under
            its current investment management arrangements. 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
                Administrative Fee 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-- 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 Class D 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 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.

</TABLE>

            The Fund attempts to provide a total return which exceeds the
            return of the S&P 500 Index by investing in a broadly diversified
            portfolio of at least 200 common stocks. The Fund also attempts to
            achieve higher after-tax returns for its shareholders by using a
            variety of tax-efficient management strategies.

             The Fund seeks to achieve its investment objective by normally
            investing at least 95% of its assets in stocks represented in the
            S&P 500 Index. The Fund's portfolio is designed to have certain
            characteristics that are similar to those of the index, including
            such measures as dividend yield, P/E ratio, relative volatility,
            economic sector exposure, return on equity and market price-to-
            book value ratio. The Fund's return is intended to correlate
            highly with the return of the S&P 500 Index, but the portfolio
            managers attempt to produce a higher total return than the index
            by selecting a portion of the stocks represented in the index
            using the quantitative techniques described below. The portfolio
            managers also use these techniques to make sell decisions.
            Notwithstanding these strategies, there is no assurance that the
            Fund's investment performance will equal or exceed that of the S&P
            500 Index.

             The Fund intends to be fully invested in common stock (aside from
            certain cash management practices) and will not make defensive
            investments in response to unfavorable market and other
            conditions.

             Quantitative Techniques. The portfolio managers use a proprietary
            quantitative model that ranks companies based on long-term (5-10
            years) price appreciation potential. They analyze factors such as
            growth of sustainable earnings and dividend behavior. Stocks in
            the top 50% of the model's ranking are considered for purchase by
            the Fund. The Fund looks to sell stocks selected from the bottom
            20% of the model's ranking based on cost, current market value and
            anticipated benefit of replacement. The portfolio managers' sell
            discipline also focuses on reducing realized capital gains as
            indicated below.

             Tax-Efficient Strategies. The portfolio managers utilize a range
            of active tax management strategies designed to minimize the
            Fund's taxable distributions, including low portfolio turnover and
            favoring investments in low-dividend, growth-oriented companies.
            The portfolio managers also identify specific shares of stock to
            be sold that have the lowest tax cost. When prudent, stocks are
            also sold to realize capital losses in order to offset realized
            capital gains. In limited circumstances, the Fund may also
            distribute appreciated securities to shareholders to meet
            redemption requests so as to avoid realizing capital gains.
            Despite the use of these tax-efficient strategies, the Fund may
            realize gains and shareholders will incur tax liability from time
            to time.

            Among the principal risks of investing in the Fund, which could

            (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
                Administrative Fee 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--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 and 0.01% in other expenses
                attributable to that class during the most recent fiscal year.

            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 Class D 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 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.

</TABLE>

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of companies
            with market capitalizations of more than $5 billion at the time of
            investment and below-average valuations whose business
            fundamentals are expected to improve. To achieve income, the Fund
            invests a portion of its assets in income-producing (e.g.,
            dividend-paying) common stocks.

             The portfolio manager selects stocks for the Fund using a "value"
            style. The portfolio manager invests primarily in stocks of
            companies having below-average valuations whose business
            fundamentals are expected to improve. The portfolio manager
            determines valuation based on characteristics such as price-to-
            earnings, price-to-book, and price-to-cash flow ratios. The
            portfolio manager analyzes stocks and seeks to identify the key
            drivers of financial results and catalysts for change, such as new
            management and new or improved products, that indicate a company
            may demonstrate improving fundamentals in the future. The
            portfolio manager looks to sell a stock when he believes that the
            company's business fundamentals are weakening or when the stock's
            valuation has become excessive.

             The Fund may also invest to a limited degree in other kinds of
            equity securities, including preferred stocks and convertible
            securities. The Fund may invest up to 15% of its assets in foreign
            securities, except that it may invest without limit in American
            Depository Receipts (ADR's). In response to unfavorable market and
            other conditions, the Fund may make temporary investments of some
            or all of its assets in high-quality fixed income securities. This
            would be inconsistent with the Fund's investment objective and
            principal strategies.

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

              . Issuer Risk        Risk                     . Management 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. For periods prior to the inception of the
            Fund's Class D shares (4/8/98), performance information shown in
            the bar chart (including 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. The prior Institutional Class performance has been
            adjusted to reflect the actual distribution and/or service (12b-1)
            fees and other expenses paid by Class D shares. Prior to May 8,
            2000, the Fund had a different sub-adviser and would not
            necessarily have achieved the performance results shown on the
            next page under its current investment management arrangements.
            Past performance is no guarantee of future results.

            (1) The Russell 1000 Value Index is an unmanaged index that
                measures the performance of companies in the Russell 1000
                Index considered to have less than average growth orientation.
                It is not possible to invest directly in the index. The
                Russell 1000 Value Index replaced the S&P 500 Index (an
                unmanaged index of large capitalization common stocks) as the
                Fund's comparative index because PIMCO Advisors believes that
                the Russell 1000 Value Index is more representative of the
                Fund's investment strategies. For periods ended December 31,
                1999, the 1 Year, 5 Year and Fund Inception average annual
                total returns of the S&P 500 Index were 21.04%, 28.56% and
                19.70%, respectively.
            (2) The Lipper Multi-Cap Value Funds Average is a total return
                performance average of funds tracked by Lipper Analytical
                Services, Inc. that invest in companies with a variety of
                capitalization ranges, without concentrating in any one market
                capitalization range over an extended period of time. It does
                not take into account sales charges.

            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 summarized 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
            each 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.

Market      The market price of securities owned by a Fund may go up or down,
Risk        sometimes rapidly or unpredictably. Each of the Funds normally
            invests most of its assets in common stocks and/or other equity
            securities. A principal risk of investing in each Fund is that the
            equity securities in its portfolio will decline in value due to
            factors affecting equity securities markets generally or
            particular industries represented in those markets. The values of
            equity securities 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.

Value
Securities  Each Fund may invest in companies that may not be expected to
Risk        experience significant earnings growth, but whose securities its
            portfolio manager believes are selling at a price lower than their
            true value. The Capital Appreciation, Equity Income, Growth &
            Income, Mid-Cap, Renaissance, Allianz Select International, Tax-
            Efficient Equity and Value Funds may place particular emphasis on
            value securities. Companies that issue value securities may have
            experienced adverse business developments or may be subject to
            special risks that have caused their securities to be out of
            favor. If a portfolio manager's assessment of a company's
            prospects is wrong, or if the market does not recognize the value
            of the company, the price of its securities may decline or may not
            approach the value that the portfolio manager anticipates.

Growth
Securities  Each Fund may invest in equity securities of companies that its
Risk        portfolio manager believes will experience relatively rapid
            earnings growth. The Capital Appreciation, Global Innovation,
            Growth, Growth & Income, Innovation, Mid-Cap, Select Growth,
            Allianz Select International, Target and Tax-Efficient Equity
            Funds may place particular emphasis on growth securities. Growth
            securities typically trade at higher multiples of current earnings
            than other securities. Therefore, the values of growth securities
            may be more sensitive to changes in current or expected earnings
            than the values of other securities.

Smaller
Company     The general risks associated with equity securities and liquidity
Risk        risk are particularly pronounced for securities of companies with
            smaller market capitalizations. These companies may have limited
            product lines, markets or financial resources or they may depend
            on a few key employees. Securities of smaller companies may trade
            less frequently and in lesser volume than more widely held
            securities and their values may fluctuate more sharply than other
            securities. They may also trade in the over-the-counter market or
            on a regional exchange, or may otherwise have limited liquidity.
            The Global Innovation and Innovation Funds generally have
            substantial exposure to this risk. The Growth & Income, Mid-Cap,
            Allianz Select International and Target Funds have significant
            exposure to this risk because they invest primarily in companies
            with medium-sized market capitalizations, which are smaller and
            generally less-seasoned than the largest companies.

IPO Risk

            The Funds, particularly the Global Innovation Fund, may purchase
            securities in initial public offerings (IPOs). These securities
            are subject to many of the same risks as investing in companies
            with smaller market capitalizations. Securities issued in IPOs
            have no trading history, and information about the companies may
            be available for very limited periods. In addition, the prices of
            securities sold in IPOs may be highly volatile. At any particular
            time or from time to time a Fund

31 PIMCO Funds: Multi-Manager Series
<PAGE>


            may not be able to invest in securities issued in IPOs, or invest
            to the extent desired, because, for example, only a small portion
            (if any) of the securities being offered in an IPO may be made
            available to the Fund. In addition, under certain market
            conditions a relatively small number of companies may issue
            securities in IPOs. Similarly, as the number of Funds to which IPO
            securities are allocated increases, the number of securities
            issued to any one Fund may decrease. The investment performance of
            a Fund during periods when it is unable to invest significantly or
            at all in IPOs may be lower than during periods when the Fund is
            able to do so. In addition, as a Fund increases in size, the
            impact of IPOs on the Fund's performance will generally decrease.

Liquidity   All of the Funds are subject to liquidity risk. Liquidity risk
Risk        exists when particular investments are difficult to purchase or
            sell, possibly preventing a Fund from selling such illiquid
            securities at an advantageous time or price. Funds with principal
            investment strategies that involve securities of companies with
            smaller market capitalizations, foreign securities, derivatives or
            securities with substantial market and/or credit risk tend to have
            the greatest exposure to liquidity risk.

Derivatives
Risk        All Funds except the Capital Appreciation and Mid-Cap Funds may
            use derivatives, which are financial contracts whose 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 may sometimes use derivatives 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, which increases opportunities for gain but also
            involves greater risk of loss due to 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, 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. In addition, a Fund's use of derivatives may
            increase or accelerate the amount of taxes payable by
            shareholders. 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.

Sector      In addition to other risks, Funds that invest a substantial
Specific    portion of their assets in related industries (or "sectors") may
Risks       have greater risk because companies in these sectors may share
            common characteristics and may react similarly to market
            developments.

            Technology Related Risk. Because the Global Innovation and
            Innovation Funds concentrate their investments in companies which
            utilize innovative technologies, they are subject to risks
            particularly affecting those companies, such as the risks of short
            product cycles and rapid obsolescence of products and services,
            competition from new and existing companies, significant losses
            and/or limited earnings, security price volatility and limited
            operating histories. Other Funds may also be subject to these
            risks to the extent they invest their assets in technology or
            technology-related companies.

Foreign
(non-       A Fund that invests in foreign securities, and particularly the
U.S.)       Global Innovation and Allianz Select International Funds, may
Investment  experience more rapid and extreme changes in value than Funds that
Risk        invest exclusively in securities of U.S. issuers or securities
            that trade exclusively in U.S. markets. The securities markets of
            many foreign countries are relatively small, with a 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. To
            the extent that a Fund, such as the Global Innovation or Allianz
            Select International Fund, invest a significant portion of their
            assets in a narrowly defined area such as Europe, Asia or South
            America, the Fund will generally have more exposure to regional
            economic risks associated with foreign investments. Adverse
            developments in certain regions (such as Southeast Asia) can also
            adversely affect securities of other countries whose economies
            appear to be unrelated. In addition, special U.S. tax
            considerations may apply to a Fund's investment in foreign
            securities.

                                                                   Prospectus 32
<PAGE>

Emerging
Markets     Foreign investment risk may be particularly high to the extent
Risk        that a Fund invests in emerging market securities of issuers based
            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. The Global Innovation
            and Allianz Select International Funds may invest a significant
            portion of their assets in emerging markets securities. In
            addition, the risks associated with investing in a narrowly
            defined geographic area (discussed above under "Foreign (non-U.S.)
            Investment Risk") are generally more pronounced with respect to
            investments in emerging market countries.

Currency
Risk        Funds that invest directly in foreign currencies and in securities
            that trade in, or receive revenues in, foreign 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. The Global Innovation and Allianz Select
            International Funds are particularly sensitive to Currency Risk.
            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.

Focused
Investment  Focusing Fund investments in a small number of issuers, industries
Risk        or foreign currencies or regions increases risk. Funds, such as
            the Select Growth Fund, that are "non-diversified" because they
            invest in a relatively small number of issuers may have more risk
            because changes in the value of a single security or the impact of
            a single economic, political or regulatory occurrence may have a
            greater adverse impact on the Fund's net asset value. Some of
            those issuers also may present substantial credit or other risks.
            The Global Innovation and Allianz Select International Funds may
            be subject to increased risk to the extent that they focus their
            investments in securities denominated in a particular foreign
            currency or in a narrowly defined geographic area outside the
            U.S., because companies in these areas may share common
            characteristics and are often subject to similar business risks
            and regulatory burdens, and their securities may react similarly
            to economic, market, political or other developments. Similarly,
            the Global Innovation and Innovation Funds are vulnerable to
            events affecting companies which use innovative technologies to
            gain a strategic, competitive advantage in their industry and
            companies that provide and service those technologies because
            these Funds normally "concentrate" their investments in those
            companies. Also, the Funds may from time to time have greater risk
            to the extent they invest a substantial portion of their assets in
            companies in related industries such as "technology" or "financial
            and business services," which may share common characteristics,
            are often subject to similar business risks and regulatory
            burdens, and whose securities may react similarly to economic,
            market, political or other developments.

Leveraging
Risk        Leverage, including borrowing, will cause the value of a Fund's
            shares to be more volatile than if the Fund did not use leverage.
            This is because leverage tends to exaggerate the effect of any
            increase or decrease in the value of a Fund's portfolio
            securities. The Funds, and in particular the Global Innovation and
            Tax-Efficient Equity Funds, may engage in transactions or purchase
            instruments that give rise to forms of leverage. Such transactions
            and instruments may include, among others, the use of reverse
            repurchase agreements and other borrowings, the investment of
            collateral from loans of portfolio securities, or the use of when-
            issued, delayed-delivery or forward commitment transactions. The
            use of derivatives may also involve leverage. The use of leverage
            may also cause a Fund to liquidate portfolio positions when it
            would not be advantageous to do so in order to satisfy its
            obligations or to meet segregation requirements.

Interest    To the extent that Funds purchase fixed income securities for
Rate Risk   investment or defensive purposes, they will be subject to interest
            rate risk, a market risk relating to investments in fixed income
            securities such as bonds and notes. The Growth & Income Fund is
            particularly sensitive to this risk because it may invest in
            interest rate sensitive securities such as corporate bonds.

             As interest rates rise, the value of fixed income securities in a
            Fund's portfolio are likely to decrease. Securities with longer
            "durations" (defined below) tend to be more sensitive to changes
            in interest rates, usually making them more volatile than
            securities with shorter durations. 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. Generally, 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.

33 PIMCO Funds: Multi-Manager Series

Credit      All of the Funds are subject to credit risk. This is the risk that
Risk        the issuer or the guarantor of a fixed 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 their credit ratings.

High
Yield       Funds that invest in high yield securities and unrated securities
Risk        of similar quality (commonly known as "junk bonds") may be subject
            to greater levels of interest rate, credit and liquidity risk than
            Funds that do not invest in such securities. The Growth & Income
            Fund is particularly susceptible to this risk. These securities
            are considered predominantly 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 these securities and reduce
            a Fund's ability to sell them .

Management  Each Fund is subject to management risk because it is an actively
Risk        managed investment portfolio. PIMCO Advisors, the Sub-Advisers 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.

            Management of the Funds

Investment  PIMCO Advisors serves as the investment adviser and the
Adviser     administrator (serving in its capacity as administrator, the
and Ad-     "Administrator") for the Funds. Subject to the supervision of the
ministrator Board of Trustees, PIMCO Advisors is responsible for managing,
            either directly or through others selected by it, the investment
            activities of the Funds and the Funds' business affairs and other
            administrative matters.

             PIMCO Advisors is located at 800 Newport Center Drive, Newport
            Beach, California 92660. Organized in 1987, PIMCO Advisors
            provides investment management and advisory services to private
            accounts of institutional and individual clients and to mutual
            funds. As of September 30, 2000, PIMCO Advisors and its subsidiary
            partnerships had approximately $272 billion in assets under
            management.

             PIMCO Advisors has retained investment management firms ("Sub-
            Advisers") to manage the investments of the Capital Appreciation,
            Mid-Cap, Allianz Select International and Tax-Efficient Equity
            Funds. The PIMCO Equity Advisors division of PIMCO Advisors
            manages the investments of the Equity Income, Global Innovation,
            Growth, Growth & Income, Innovation, Renaissance, Select Growth,
            Target and Value Funds. (PIMCO Equity Advisors is also referred to
            as a "Sub-Adviser" in this capacity.) See "Sub-Advisers" below.

             PIMCO Advisors has retained its affiliate, Pacific Investment
            Management Company LLC ("Pacific Investment Management Company"),
            to provide various administrative and other services required by
            the Funds in its capacity as sub-administrator. PIMCO Advisors and
            the sub-administrator may retain other affiliates to provide
            certain of these services.

Advisory    Each Fund pays PIMCO Advisors fees in return for providing or
Fees        arranging for the provision of investment advisory services. In
            the case of Funds for which PIMCO Advisors has retained a separate
            Sub-Adviser, PIMCO Advisors (and not the Fund) pays a portion of
            the advisory fees it receives to the Sub-Adviser in return for its
            services.
                                                                   Prospectus 34

             For the fiscal year ended June 30, 2000, the Funds paid monthly
            advisory fees to PIMCO Advisors at the following annual rates
            (stated as a percentage of the average daily net assets of each
            Fund taken separately):

            * On April 1, 2000, the advisory fee rate for the Select Growth
            Fund increased from 0.57% to 0.60% per annum. On May 8, 2000, the

            advisory fee rate for the Growth & Income Fund decreased from

             The Global Innovation Fund was not operational during the entire
            fiscal year ended June 30, 2000. The annual investment advisory
            fee rate payable by this Fund is 1.00% (stated as a percentage of
            the average daily net assets of the Fund).

Administrative
Fees

            Each Fund pays for the administrative services it requires under a
            fee structure which is essentially fixed. Class D shareholders of
            each Fund pay an administrative fee to PIMCO Advisors, computed as
            a percentage of the Fund's assets attributable in the aggregate to
            Class D shares. PIMCO Advisors, in turn, provides or procures
            administrative services for Class D shareholders and also bears
            the costs of most third-party services required by the Funds,
            including audit, custodial, portfolio accounting, legal, transfer
            agency and printing costs. The Funds do bear other expenses which
            are not covered under the administrative fee which may vary and
            affect the total level of expenses paid by Class D shareholders,
            such as brokerage fees, commissions and other transaction
            expenses, costs of borrowing money, including interest expenses,
            and fees and expenses of the Trust's disinterested Trustees.

             PIMCO Advisors or an affiliate may pay financial service firms a
            portion of the Class D administrative fees in return for the
            firms' 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).

             Class D shareholders of the Funds pay PIMCO Advisors monthly
            administrative fees at the following annual rates (stated as a
            percentage of the average daily net assets attributable in the
            aggregate to the Fund's Class D shares):

             *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
             0.65% (0.75% for the Growth & Income Fund, 0.85% for the Global
             Innovation Fund and 0.95% for the Allianz Select International
             Fund) 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 0.65% (0.75% for the Growth & Income Fund, 0.85% for
             the Global Innovation Fund and 0.95% for the Allianz Select
             International Fund) Administrative Fee rate under two separate
             columns entitled "Distribution and/or Service (12b-1) Fees"
             (0.25%) and "Other Expenses" (0.40%) (0.50% for the Growth &
             Income Fund, 0.60% for the Global Innovation Fund and 0.70% for
             the Select International Fund).

12b-1
Plan for    The Funds' administration agreement includes a plan for Class D
Class D     shares that has been adopted in conformity with the requirements
Shares      set forth in Rule 12b-1 under the 1940 Act. The plan provides that
            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 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 quotes are not readily
            available may be valued, pursuant to procedures established by the
            Board of Trustees, with reference to other securities or 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. In particular, calculation of the NAV
            of the Global Innovation and Allianz Select International Funds
            may not take place contemporaneously with the determination of the
            prices of foreign securities used in NAV calculations.

             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 their 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 or persons acting at their direction pursuant to

            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
Information
              . Financial Service Firms. Broker-dealers, registered investment
            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

39 PIMCO Funds: Multi-Manager Series
<PAGE>

            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
            affiliate (normally not to exceed an annual rate of 0.35% of a
            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
            materials regarding its fees and services.

              . 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" above 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, PFPC, Inc., 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.

             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 New York Stock 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.

                                                                   Prospectus 40

Investment  The following investment minimums apply for purchases of Class D
Minimums    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  Except as provided below or in the applicable Fund's or series'
Shares      prospectus(es), you may exchange your Class D shares of any Fund
            for Class D shares of any other Fund or series of PIMCO Funds:
            Pacific Investment Management 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. In addition, an exchange is generally a
            taxable event which will generate capital gains or losses, and
            special rules may apply in computing tax basis when determining
            gain or loss. 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 Advisors, 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 Advisors 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 PIMCO 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 with respect to Class D shares.

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
            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
In Kind

            The Trust has agreed to redeem shares of each Fund solely in cash
            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

41 PIMCO Funds: Multi-Manager Series
<PAGE>

            for Funds with a tax-efficient management strategy, it is highly
            unlikely that your shares would ever be 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.

            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 its
            Class D 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.

</TABLE>

             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.

            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
              another series of the Trust or PIMCO Funds: Pacific Investment
              Management 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.

             For further information on distribution options, please contact
            your financial service firm or call the Distributor at 1-888-87-
            PIMCO.

            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 them
            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.

                                                                   Prospectus 42
<PAGE>

             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 generally 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.

              . A Note on the Tax-Efficient Equity Fund. The Tax-Efficient
            Equity Fund utilizes a number of tax-efficient management
            techniques designed to minimize taxable distributions. For
            instance, the Fund generally seeks to minimize realized gains and,
            when realizing gains, attempts to realize gains that will be taxed
            as capital gains (i.e., as gains on investments owned for more
            than 12 months) when distributed to shareholders. Although the
            Fund attempts to minimize taxable distributions, it may be
            expected to earn and distribute taxable income and realize and
            distribute capital gains from time to time.

              . A Note on Foreign Investments. A Fund's investment in foreign
            securities may be subject to foreign withholding taxes. In that
            case, the Fund's yield on those securities would be decreased. In
            addition, a Fund's investments in foreign securities or foreign
            currencies may increase or accelerate the Fund's recognition of
            ordinary income and may affect the timing or amount of the Fund's
            distributions. Shareholders of the Global Innovation and Allianz
            Select International Funds may be entitled to claim a credit or
            deduction with respect to foreign taxes.

             This section relates only to federal income tax consequences of
            investing in the Funds; the consequences under other tax laws may
            differ. You should consult your tax advisor as to the possible
            application of foreign, state and local income tax laws to Fund
            dividends and capital distributions. Please see the Statement of
            Additional Information for additional information regarding the
            tax aspects of investing in the Funds.

            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 identified
            under "Summary Information" above. It also describes
            characteristics and risks of additional securities and investment
            techniques that are not necessarily principal investment
            strategies but may be used by the Funds from time to time. Most of
            these securities and investment techniques are discretionary,
            which means that the portfolio managers 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 must rely on the professional investment judgment and skill
            of PIMCO Advisors, the Sub-Advisers 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.

Fixed       Fixed income securities are obligations of the issuer to make

and         commercial paper, convertible securities and mortgage-backed and
Defensive   other asset-backed securities.
Strategies

             The Capital Appreciation, Mid-Cap and Tax-Efficient Equity Funds
            intend to be as fully invested in common stocks as practicable at
            all times, although, for cash management purposes, each of these
            Funds may maintain a portion of its assets (normally not more than
            10%) in U.S. Government securities, high quality fixed income
            securities, money market obligations and cash to pay certain Fund
            expenses and to meet redemption requests. None of these Funds will
            make defensive investments in response to unfavorable market and
            other conditions and therefore may be particularly vulnerable to
            general declines in stock prices and/or other categories of
            securities in which they invest.

             The Equity Income, Global Innovation, Growth, Innovation,
            Renaissance, Select Growth, Allianz Select International, Target
            and Value Funds will each invest primarily in common stocks, and
            may also invest in other kinds of equity securities, including
            preferred stocks and securities (including fixed

            income securities and warrants) convertible into or exercisable
            for common stocks. Each of these Funds may also invest a portion
            of its assets in fixed income securities. These Funds may
            temporarily hold up to 100% of their assets in short-term U.S.
            Government securities and other money market instruments for
            defensive purposes in response to unfavorable market and other
            conditions. The Growth & Income Fund will invest primarily in
            common stocks, but may also invest significant portions of its
            assets in preferred stocks, fixed income securities, convertible
            securities and real estate investment trusts, or "REITs." The
            Growth & Income Fund may temporarily hold up to 100% of its assets
            in short-term U.S. Government securities and other money market
            instruments for defensive purposes in response to unfavorable
            market and other conditions. The Allianz Select International Fund
            may also hold up to 100% of its assets in other domestic fixed
            income, foreign fixed income and equity securities principally
            traded in the U.S., including obligations issued or guaranteed by
            a foreign government or its agencies, authorities or
            instrumentalities, corporate bonds and American Depository
            Receipts, for temporary defensive purposes. The temporary
            defensive strategies described in this paragraph would be
            inconsistent with the investment objective and principal
            investment strategies of each of the noted Funds and may adversely
            affect the Fund's ability to achieve its investment objective.

Companies
With
Smaller
Market
Capitalizations

            Each of the Funds may invest in securities of companies with
            market capitalizations that are small compared to other publicly
            traded companies. The Global Innovation and Innovation Funds may
            invest significant portions of their assets in smaller companies
            and therefore have substantial exposure to the risks described
            below. The Growth & Income, Mid-Cap, Allianz Select International
            and Target Funds also have significant exposure to the risks
            described below because they invest primarily in companies with
            medium-sized market capitalizations, which are smaller and
            generally less well-known or seasoned than the largest companies.

             Companies which are smaller and less well-known or seasoned than
            larger, more widely held companies may offer greater opportunities
            for capital appreciation, but may also involve risks different
            from, or greater than, risks normally associated with larger
            companies. Larger companies generally have greater financial
            resources, more extensive research and development, manufacturing,
            marketing and service capabilities, and more stability and greater
            depth of management and technical personnel than smaller
            companies. Smaller companies may have limited product lines,
            markets or financial resources or may depend on a small,
            inexperienced management group. Securities of smaller companies
            may trade less frequently and in lesser volume than more widely
            held securities and their values may fluctuate more abruptly or
            erratically than securities of larger companies. They may also
            trade in the over-the-counter market or on a regional exchange, or
            may otherwise have limited liquidity. These securities may
            therefore be more vulnerable to adverse market developments than
            securities of larger companies. Also, there may be less publicly
            available information about smaller companies or less market
            interest in their securities as compared to larger companies, and
            it may take longer for the prices of the securities to reflect the
            full value of a company's earnings potential or assets.

             Because securities of smaller companies may have limited
            liquidity, a Fund may have difficulty establishing or closing out
            its positions in smaller companies at prevailing market prices. As
            a result of owning large positions in this type of security, a
            Fund is subject to the additional risk of possibly having to sell
            portfolio securities at disadvantageous times and prices if
            redemptions require the Fund to liquidate its securities
            positions. For these reasons, it may be prudent for a Fund with a
            relatively large asset size to limit the number of relatively
            small positions it holds in securities having limited liquidity in
            order to minimize its exposure to such risks, to minimize
            transaction costs, and to maximize the benefits of research. As a
            consequence, as a Fund's asset size increases, the Fund may reduce
            its exposure to illiquid smaller capitalization securities, which
            could adversely affect performance.

Initial     The Funds, particularly the Global Innovation Fund, may purchase
Public      securities in intial public offerings (IPOs). These securities are
Offerings   subject to many of the same risks of investing in companies with
            smaller market capitalizations. Securities issued in IPOs have no
            trading history, and information about the companies may be
            available for very limited periods. In addition, the prices of
            securities sold in IPOs may be highly volatile. At any particular
            time or from time to time a Fund may not be able to invest in
            securities issued in IPOs, or invest to the extent desired
            because, for example, only a small portion (if any) of the
            securities being offered in an IPO may be made available to the
            Fund. In addition, under certain market conditions a relatively
            small number of companies may issue securities in IPOs. Similarly,
            as the number of Funds to which IPO securities are allocated
            increases, the number of securities issued to any one Fund may
            decrease. The investment performance of a Fund during periods when
            it is unable to invest significantly or at all in IPOs may be
            lower than during periods when the Fund is able to do so. In
            addition, as a Fund increases in size, the impact of IPOs on the
            Fund's performance will generally decrease.

                                                                   Prospectus 44

Foreign
(non-       The Allianz Select International Fund normally invests principally
U.S.)       in securities of foreign issuers, securities traded principally in
Securities  securities markets outside the United States and/or securities
            denominated in foreign currencies (together, "foreign
            securities"). The Global Innovation Fund will invest in the
            securities of issuers located in at least three countries (one of
            which may be the United States). The Equity Income, Growth, Growth
            & Income, Innovation, Renaissance, Target and Value Funds may
            invest up to 15% of their respective assets in securities of
            foreign issuers, securities traded principally in securities
            markets outside the United States and/or securities denominated in
            foreign currencies (together, "foreign securities"). The Select
            Growth Fund may invest up to 25% of its assets in foreign
            securities. Each of these Funds may invest without limit in ADRs
            (defined below). The Tax-Efficient Equity Fund may invest in
            common stocks of foreign issuers if included in the S&P 500 Index.

             All of the Funds may invest in American Depository Receipts
            (ADRs). In addition, the Equity Income, Global Innovation, Growth,
            Growth & Income, Innovation, Renaissance, Select Growth, Allianz
            Select International, Target and Value Funds may invest in
            European Depository Receipts (EDRs) and Global Depository Receipts
            (GDRs). ADRs are dollar-denominated receipts issued generally by
            domestic banks and representing the deposit with the bank of a
            security of a foreign issuer, and are publicly traded on exchanges
            or over-the-counter in the United States. EDRs are receipts
            similar to ADRs and are issued and traded in Europe. GDRs may be
            offered privately in the United States and also traded in public
            or private markets in other countries.

             Investing in foreign securities involves special risks and
            considerations not typically associated with investing in U.S.
            securities and shareholders should consider carefully the
            substantial risks involved for Funds that invest in these
            securities. 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, rate
            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.

Emerging
Market      Each of the Funds that may invest in foreign securities may invest
Securities  in securities of issuers based in countries with developing (or
            "emerging market") economies. The Global Innovation and Allianz
            Select International Funds may invest significant portions of
            their assets in emerging market 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; and possible repatriation of investment income and
            capital. In addition, foreign investors may be required to
            register the proceeds of sales and future economic or political
            crises could lead to price controls, forced mergers, expropriation
            or confiscatory taxation, seizure, nationalization or the 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 market 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.

45 PIMCO Funds: Multi-Manager Series

             Special Risks of Investing in Russian and Other Eastern European
            Securities. Each of the Global Innovation and Allianz Select
            International Funds may invest a significant portion of its assets
            in securities of issuers located in Russia and in other Eastern
            European countries. While investments in securities of such
            issuers are subject generally to the same risks associated with
            investments in other emerging market countries described above,
            the political, legal and operational risks of investing in Russian
            and other Eastern European issuers, and of having assets custodied
            within these countries, may be particularly acute. A risk of
            particular note with respect to direct investment in Russian
            securities is the way in which ownership of shares of companies is
            normally recorded. When a Fund invests in a Russian issuer, it
            will normally receive a "share extract," but that extract is not
            legally determinative of ownership. The official record of
            ownership of a company's share is maintained by the company's
            share registrar. Such share registrars are completely under the
            control of the issuer, and investors are provided with few legal
            rights against such registrars.

Foreign
Currencies  A Fund that invests directly in foreign currencies or in
            securities that trade in, and receive revenues in, foreign
            currencies will be subject to currency risk. The Global Innovation
            and Allianz Select International Funds are particularly sensitive
            to this risk.

             Foreign currency exchange rates may fluctuate significantly over
            short periods of time. They generally are determined by supply and
            demand 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, uncertainty
            surrounds the introduction of the euro (a common currency unit for
            the European Union) and the effect it may have on the value of
            European currencies as well as 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. The Equity Income, Global
            Innovation, Growth, Growth & Income, Innovation, Renaissance,
            Select Growth, Allianz Select International, Target and Value
            Funds may enter into forward foreign currency exchange contracts,
            primarily to reduce the risks of adverse changes in foreign
            exchange rates. In addition, the Global Innovation and Allianz
            Select International Funds may buy and sell foreign currency
            futures contracts and options on foreign currencies and foreign
            currency 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. Contracts to sell foreign
            currency would limit any potential gain which might be realized by
            a Fund if the value of the hedged currency increases. A Fund may
            enter into these contracts to hedge against foreign exchange risk
            arising from the Fund's investment or anticipated investment in
            securities denominated in foreign currencies. 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.

             The Global Innovation and Allianz Select International Funds may
            also enter into these contracts for purposes of increasing
            exposure to a foreign currency or to shift exposure to foreign
            currency fluctuations from one currency to another. To the extent
            that it does so, the Fund will be subject to the additional risk
            that the relative value of currencies will be different than
            anticipated by the Fund's portfolio manager. The Global Innovation
            and Allianz Select International Funds may use one currency (or
            basket of currencies) to hedge against adverse changes in the
            value of another currency (or basket of currencies) when exchange
            rates between the two currencies are positively correlated. The
            Fund will segregate assets determined to be liquid by PIMCO
            Advisors or its Sub-Adviser 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.

Corporate
Debt
Securities

            Each Fund that may invest in fixed income securities may invest in
            corporate debt securities. The Growth & Income Fund may invest up
            to 10% of its assets in these securities. Corporate debt
            securities are subject to the risk of the issuer's inability to
            meet principal and interest payments on the obligation and may
            also be subject to price volatility due to factors such as
            interest rate sensitivity, market perception of the
            creditworthiness of the issuer and general market liquidity. When
            interest rates rise,

                                                                   Prospectus 46
<PAGE>

            the value of corporate debt securities can be expected to decline.
            Debt securities with longer durations tend to be more sensitive to
            interest rate movements than those with shorter durations.

Convertible Each Fund may invest in convertible securities. The Growth &
Securities  Income Fund may place particular emphasis on convertible
            securities. Convertible securities are generally preferred stocks
            and other securities, including fixed income securities and
            warrants, that are convertible into or exercisable for common
            stock at either a stated price or a stated 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. While
            convertible securities generally offer lower interest or dividend
            yields than non-convertible fixed income securities of similar
            quality, their value tends to increase as the market value of the
            underlying stock increases and to decrease when the value of the
            underlying stock decreases. Also, 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.

Derivatives
            Each Fund (except the Capital Appreciation and Mid-Cap Funds) may,
            but is not required to, use a number of 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. 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. In addition, 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.

             Examples of derivative instruments that the Funds may use include
            options contracts, futures contracts, options on futures contracts
            and swap agreements. The Equity Income, Global Innovation, Growth,
            Growth & Income, Innovation, Renaissance, Select Growth, Allianz
            Select International, Target, Tax-Efficient Equity and Value Funds
            may purchase and sell (write) call and put options on securities,
            securities indexes and foreign currencies. Each of these Funds may
            purchase and sell futures contracts and options thereon with
            respect to securities, securities indexes and foreign currencies.
            The Global Innovation, Allianz Select International and Tax-
            Efficient Equity Funds may enter into swap agreements with respect
            to securities indexes. 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 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.

             Leveraging 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

47 PIMCO Funds: Multi-Manager Series
<PAGE>

            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 Advisors or a Sub-Adviser 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 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
            (taxed at ordinary income tax rates when distributed to
            shareholders who are individuals) than if the Fund had not used
            such instruments.

Equity-     The Funds may invest in equity-linked securities. The Allianz
Linked      Select International Fund may invest up to 15% of its assets in
Securities  equity-linked securities. Equity-linked securities are privately
            issued securities whose investment results are designed to
            correspond generally to the performance of a specified stock index
            or "basket" of stocks, or sometimes a single stock. To the extent
            that the Funds invest in equity-linked securities whose return
            corresponds to the performance of a foreign securities index or
            one or more of foreign stocks, investing in equity-linked
            securities will involve risks similar to the risks of investing in
            foreign securities. See "Foreign Securities" above. In addition,
            the Funds bear the risk that the issuer of an equity-linked
            security may default on its obligations under the security.
            Equity-linked securities may be considered illiquid and thus
            subject to each Fund's restrictions on investments in illiquid
            securities.

Credit      The Funds may invest in securities based on their credit ratings
Ratings     assigned by rating agencies such as Moody's Investors Service,
and         Inc. ("Moody's") and Standard & Poor's Ratings Services ("S&P").
Unrated     Moody's, S&P and other rating agencies are private services that
Securities  provide ratings of the credit quality of fixed income securities,
            including convertible securities. The Appendix to the Statement of
            Additional Information 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 risk. 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 Advisors and the
            Sub-Advisers do not rely solely on credit ratings, and develop
            their 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.

High
Yield
Securities

            Securities rated lower than Baa by Moody's or lower than BBB by
            S&P are sometimes referred to as "high yield securities" or "junk
            bonds." The Funds, particularly the Growth & Income Fund, may
            invest in these securities. Investing in these securities involves
            special risks in addition to the risks associated with investments
            in higher-rated fixed income securities. While offering a greater
            potential

                                                                   Prospectus 48
<PAGE>


            opportunity for capital appreciation and higher yields, these
            securities may be subject to greater levels of interest rate,
            credit and liquidity risk, may entail greater potential price
            volatility and may be less liquid than higher-rated securities.
            These securities may be regarded as predominantly 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.

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 the party arranging the loan.

Short       Each Fund may make short sales as part of its overall portfolio
Sales       management strategies or to offset a potential decline in the
            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. A Fund may only enter into short selling transactions if
            the security sold short is held in the Fund's portfolio or if the
            Fund has the right to acquire the security without the payment of
            further consideration. 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.

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
Transactionssettlement date. This risk is in addition to the risk that the
            Fund's other assets will decline in 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 that 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. Those Funds whose investment objectives do not
            include the earning of income will invest in repurchase agreements
            only as a cash management technique with respect to that portion
            of its portfolio maintained in cash. Repurchase agreements
            maturing in more than seven days are considered illiquid
            securities.

Reverse     Each Fund may enter into reverse repurchase agreements, subject to
Repurchase  the Fund's limitations on borrowings. A reverse repurchase
Agreements  agreement involves the sale of a security by a Fund and its
And Other   agreement to repurchase the instrument at a specified time and
Borrowings  price, and may be considered a form of borrowing for some
            purposes. A Fund will segregate assets determined to be liquid by
            PIMCO Advisors or a Sub-Adviser in accordance with procedures
            established by the Board of Trustees to cover its obligations
            under reverse repurchase agreements. 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 and other
            forms of borrowings may create leveraging risk for a Fund.

Illiquid
Securities
            Each Fund may invest in securities that are illiquid so long as
            not more than 15% of the value of the Fund's net assets (taken at
            market value at the time of investment) would be invested in such
            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 held by a
            Fund, and transactions in illiquid securities may entail
            registration expenses and other transaction costs that are higher
            than those for transactions in liquid

49 PIMCO Funds: Multi-Manager Series
<PAGE>

            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. Please see "Investment Objectives
            and Policies" in the Statement of Additional Information for a
            listing of various securities that are generally considered to be
            illiquid for these purposes. 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
in Other    The Allianz Select International Fund may invest up to 10% of its
Investment  assets in securities of other investment companies, such as
Companies   closed-end management investment companies, or in pooled accounts
            or other investment vehicles which invest in foreign markets. Each
            of the other Funds may invest up to 5% of its assets in other
            investment companies. 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.

Portfolio
Turnover    With the exception of the Tax-Efficient Equity Fund, the length of
            time a Fund has held a particular security is not 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 active and frequent trading of portfolio securities to
            achieve its investment objective and principal investment
            strategies, particularly during periods of volatile market
            movements, although the Tax-Efficient Equity Fund will generally
            attempt to limit portfolio turnover as part of its tax-efficient
            management strategies. 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 taxed
            at ordinary income tax rates when distributed to shareholders who
            are individuals). The trading costs and tax effects associated
            with portfolio turnover may adversely affect a Fund's performance.
            Funds, such as the Growth & Income, Select Growth and Allianz
            Select International Funds, that have recently changed Sub-
            Advisers and/or investment objectives and policies may experience
            increased portfolio turnover due to the differences between the
            Funds' previous and current investment objectives and policies and
            portfolio management strategies.

Changes
in          The investment objective of each of the Global Innovation, Growth,
Investment  Growth & Income, Innovation, Renaissance, Select Growth, Allianz
Objectives  Select International, Target and Tax-Efficient Equity Funds
and         described in this Prospectus may be changed by the Board of
Policies    Trustees without shareholder approval. The investment objective of
            each other Fund is fundamental and may not be changed without
            shareholder approval. Unless otherwise stated in the Statement of
            Additional Information, all investment policies of the Funds may
            be changed by the Board of Trustees without shareholder approval.
            If there is a change in a Fund's investment objective or policies,
            including a change approved by shareholder vote, shareholders
            should consider whether the Fund remains an appropriate investment
            in light of their then current financial position and needs.

New and
Smaller-    In addition to the risks described under "Summary of Principal
Sized       Risks" above and in this section, several of the Funds are newly
Funds       formed and therefore have limited or no performance history for
            investors to evaluate. Also, it is possible that newer Funds and
            smaller-sized Funds may invest in securities offered in initial
            public offerings and other types of transactions (such as private
            placements) which, because of the Funds' size, have a
            disproportionate impact on the Funds' performance results. The
            Funds would not necessarily have achieved the same performance
            results if their aggregate net assets had been greater.

Percentage
Investment  Unless otherwise stated, all percentage limitations on Fund
Limitations investments listed in this Prospectus will apply at the time of
            investment. A Fund would not violate these limitations unless an
            excess or deficiency occurs or exists immediately after and as a
            result of an investment.

Other
Investments
and
Techniques
            The Funds may invest in other types of securities and use a
            variety of investment techniques and strategies which are not
            described in this Prospectus. These securities and techniques may
            subject the Funds to additional risks. Please see the Statement of
            Additional Information for additional information about the
            securities and investment techniques described in this Prospectus
            and about additional securities and techniques that may be used by
            the Funds.

            Financial Highlights

            The financial highlights table is intended to help you understand
            the financial performance of Class D shares of each Fund since the
            class of shares was first offered. Certain information reflects
            financial results for a single Fund share. The total returns in
            the table represent the rate that an investor would have earned or
            lost on an investment in Class D shares of a Fund, assuming
            reinvestment of all dividends and distributions. This information
            has been audited by PricewaterhouseCoopers LLP, whose report,
            along with each Fund's financial statements, are included in the
            Trust's annual report to shareholders. The annual report is
            incorporated by reference in the Statement of Additional
            Information and is available free of charge upon request from the
            Distributor. The Growth & Income and Allianz Select International
            Funds did not offer Class D shares during the periods shown.

(a)Per share amounts based upon average number of shares outstanding during the
period.

(b)If the investment manager had not reimbursed expenses, the ratio of operat-
ing expenses to average net assets would have been 1.94% for the period ended
June 30, 2000.
(i) The information provided for the Equity Income, Innovation, Renaissance and
    Value Funds reflects results of operations under each Funds' former Sub-
    Adviser through May 8, 2000, March 6, 1999, May 7, 1999 and May 8, 2000,
    respectively; the Funds would not necessarily have achieved the performance
    results shown above under their current investment management arrangements.

(ii) Formerly the Mid-Cap Growth Fund.

(iii) Formerly the PIMCO Core Equity Fund. The Fund changed its investment
      objective and policies on April 1, 2000; the performance results shown
      above would not necessarily have been achieved had the Fund's current
      objective and policies been in effect during the periods shown. In
      addition, the performance results shown above reflect the Fund's advisory
      fee level in effect prior to April 1, 2000; these results would have been
      lower had the Fund's current advisory fee level then been in effect.

            Summary Information

            The Portfolios are intended for investors who prefer to have their
            asset allocation decisions made by professional money managers.
            Each Portfolio has a distinct investment objective which it seeks
            to achieve by investing within specified equity and fixed income
            targets and ranges among certain Funds in the PIMCO Funds family.
            The Portfolios invest only in Funds in the PIMCO Funds family. The
            PIMCO Funds in which the Portfolios invest are called Underlying
            Funds or Funds in this Prospectus.

              Some of the Underlying Funds invest primarily in equity
            securities and are called Underlying Stock Funds. Other Underlying
            Funds invest primarily in fixed income securities, including money
            market instruments, and are called Underlying Bond Funds. The
            Portfolios are named according to their equity/fixed income
            allocation targets. For instance, the 90/10 Portfolio will
            normally invest approximately 90% of its assets in Underlying
            Stock Funds and 10% of its assets in Underlying Bond Funds.

              The table below lists the investment objectives and compares the
            asset allocation strategies of the Portfolios. Other important
            characteristics are described in the individual Portfolio
            Summaries beginning on page 5, and are discussed in greater detail
            under "Investment Objectives and Principal Investment Strategies."
            A "Summary of Principal Risks" begins on page 14.

</TABLE>

Risk/Return An investor should choose among the Portfolios based on personal
Comparison  investment objectives, investment time horizon, tolerance for risk
            and personal financial circumstances. Generally speaking,
            historical data suggests that the longer the time horizon, the
            greater the likelihood that the total return of a portfolio that
            invests primarily in equity securities will be higher than the
            total return of a portfolio that invests primarily in fixed income
            securities. However, an equity portfolio is generally subject to
            higher levels of overall risk and price volatility than a fixed
            income portfolio and is considered to be a more aggressive
            investment. Based on these assumptions, the following chart gives
            some indication of the comparative risk/return potential of the
            Portfolios according to their equity/fixed income allocation
            targets and ranges. Note that these assumptions may not be correct
            in future market conditions and the chart may not accurately
            predict the actual comparative risk/return of the Portfolios under
            all market conditions.



                90/10 Portfolio might be suitable for investors that have a
                relatively long time horizon, seek long-term capital
                appreciation potential and have a fairly high tolerance for
                risk and volatility.

                60/40 Portfolio might be suitable for investors that have a
                medium-range time horizon, seek a balance of long-term
                capital appreciation potential and income and have medium
                tolerance for risk and volatility.

                30/70 Portfolio might be suitable for investors that have a
                shorter time horizon, seek a higher level of income combined
                with some potential for long-term capital appreciation and
                have a lower tolerance for risk and volatility.



              It is possible to lose money on investments in the Portfolios.
            While each Portfolio provides a relatively high level of
            diversification in comparison to most mutual funds, a single
            Portfolio may not be suitable as a complete investment program.
            The fact that a Portfolio may have had good performance in the
            past (for example, during the year ended 1999) is no assurance
            that the value of the Fund's investments will not decline in the
            future or will appreciate at a slower rate. An investment in a
            Portfolio is not a deposit of a bank and is not guaranteed or
            insured by the Federal Deposit Insurance Corporation or any other
            government agency.

3 PIMCO Funds: Multi-Manager Series
<PAGE>

            Summary Information (continued)

Asset       PIMCO Advisors L.P. serves as the investment adviser to the
Allocation  Portfolios. PIMCO Advisors selects the Underlying Funds in which
Strategies  the Portfolios may invest. PIMCO Advisors' Asset Allocation
            Committee determines how each Portfolio allocates and reallocates
            its assets among the Underlying Funds selected by PIMCO Advisors
            according to the Portfolio's equity/fixed income allocation
            targets and ranges. The Committee attempts to diversify each
            Portfolio's assets broadly among the major asset classes and sub-
            classes represented by the Underlying Funds.

              The major equity asset classes and sub-classes held by the
            Underlying Stock Funds include those categorized by investment
            style/category (growth, blend, value, enhanced index, sector-
            related), region (U.S. equities, international developed markets,
            international emerging markets), and market capitalization (large-
            cap, mid-cap and small-cap). The major fixed income asset classes
            and sub-classes held by the Underlying Bond Funds include those
            categorized by sector/investment specialty (government securities,
            mortgage-related securities, corporate bonds and inflation-indexed
            bonds), region (U.S. fixed income, developed foreign fixed income,
            emerging markets fixed income), credit quality (investment
            grade/money market, medium grade, high yield), and duration (long-
            term, intermediate-term and short-term).

              Please see "Underlying Funds" in this Prospectus for a
            description of the Underlying Funds as categorized by their
            investment styles and main investments.

              The Portfolios may invest in any or all of the Underlying Funds,
            but will not normally invest in every Underlying Fund at any
            particular time. Each Portfolio may invest in shares of the same
            Underlying Funds; however, the percentage of each Portfolio's
            assets so invested will vary depending on the Portfolio's
            investment objective. The Asset Allocation Committee does not
            allocate a Portfolio's assets according to a predetermined blend
            of particular Underlying Funds. Instead, the Committee meets
            regularly to determine the mix of Underlying Funds appropriate for
            each Portfolio by allocating among the asset classes and sub-
            classes held by the Underlying Funds. When making these decisions,
            the Committee considers various quantitative and qualitative data
            relating to the U.S. and foreign economies and securities markets.
            This data includes projected growth trends in the U.S. and foreign
            economies, forecasts for interest rates and the relationship
            between short- and long-term interest rates (yield curve), current
            and projected trends in inflation, relative valuation levels in
            the equity and fixed income markets and various segments within
            those markets, the outlook and projected growth of various
            industrial sectors, information relating to business cycles,
            borrowing trends and the cost of capital, political trends, data
            relating to trade balances and labor information. The Committee
            may also consider proprietary research provided by the investment
            advisers and sub-advisers of the Underlying Funds.

              The Committee then allocates each Portfolio's assets among the
            Underlying Funds selected by PIMCO Advisors to fill out the asset
            class and sub-class weightings it has identified according to the
            Portfolio's equity/fixed income targets and ranges. The Committee
            has the flexibility to reallocate each Portfolio's assets in
            varying percentages among any or all of the Underlying Funds
            selected by PIMCO Advisors based on the Committee's ongoing

"Fund of    The term "fund of funds" is used to describe mutual funds, such as
Funds"      the Portfolios, that pursue their investment objectives by
Structure   investing in other mutual funds. The cost of investing in a
and         Portfolio will generally be higher than the cost of investing in a
Expenses    mutual fund that invests directly in individual stocks and bonds.
            By investing in a Portfolio, an investor will indirectly bear fees
            and expenses charged by the Underlying Funds in which the
            Portfolio invests in addition to the Portfolio's direct fees and
            expenses. In addition, the use of a fund of funds structure could
            affect the timing, amount and character of distibutions to
            shareholders and therefore may increase the amount of taxes
            payable by shareholders.

            The Portfolio seeks to achieve its investment objective by
            normally investing approximately 90% (within a range of 80%--100%)
            of its assets in Underlying Stock Funds and approximately 10%
            (within a range of0%--20%) of its assets in Underlying Bond Funds.
            The Portfolio invests all of its assets in shares of the
            Underlying Funds and does not invest directly in stocks or bonds
            of other issuers. Please see "Asset Allocation Strategies" on page
            3 for a summary of how the Asset Allocation Committee allocates
            and reallocates the Portfolio's assets among particular Underlying
            Funds.

              The Portfolio may concentrate investments in a particular
            Underlying Fund by investing more than 25% of its assets in that
            Fund.

              Based on the Portfolio's equity/fixed income allocation
            strategy, it might be suitable for an investor with a relatively
            long time horizon who seeks long-term capital appreciation
            potential and has a fairly high tolerance for risk and volatility.

--------------------------------------------------------------------------------
Principal
Risks       Allocation Risk The Portfolio's investment performance depends
            upon how its assets are allocated and reallocated among particular
            Underlying Funds. A principal risk of investing in the Portfolio
            is that the Asset Allocation Committee's allocation techniques and
            decisions and/or PIMCO Advisors' selection of Underlying Funds
            will not produce the desired results, and therefore the Portfolio
            may not achieve its investment objective.

            Underlying Fund Risks The value of your investment in the
            Portfolio is directly related to the investment performance of the
            Underlying Funds in which it invests. Therefore, the principal
            risks of investing in the Portfolio are closely related to the
            principal risks associated with the Underlying Funds and their
            investments. Because the Portfolio's allocation among the
            Underlying Funds will vary, an investment may be subject to any
            and all of these risks at different times and to different
            degrees.

            Among the principal risks of the Underlying Funds, which could
            adversely affect the net asset value, yield and total return of
            the Portfolio, are:

              .Market Risk          .Derivatives Risk   .Interest Rate Risk
              .Issuer Risk          .Foreign Investment .Credit Risk
              .Value Securities     Risk                .High Yield Risk
              Risk                  .Emerging Markets   .Mortgage Risk
              .Growth Securities    Risk                .Management Risk
              Risk                  .Currency Risk
              .Smaller Company      .Focused Investment
              Risk                  Risk
              .Liquidity Risk       .Leveraging Risk

            Please see "Summary of Principal Risks" following the Portfolio
            Summaries for a description of these and other risks associated
            with the Underlying Funds and an investment in the Portfolio.

            90/10 Portfolio (continued)

--------------------------------------------------------------------------------
Performance The following shows summary performance information for the
Information Portfolio in a bar chart and an Average Annual Total Returns
            table. The information provides some indication of the risks of
            investing in the Portfolio by showing changes in its performance
            from year to year and by showing how the Portfolio's average
            annual returns compare with the returns of broad-based securities
            market indices and an index of mutual funds. The bar chart, the
            information to its right and the Average Annual Total Returns
            table show performance of the Portfolio's Class A shares, which
            are offered in a different prospectus. This is because the
            Portfolio has not offered Institutional Class or Administrative
            Class shares for a full calendar year. Although Class A,
            Institutional Class and Administrative Class shares would have
            similar returns (because all the Portfolio's shares represent
            interests in the same portfolio of securities), Class A
            performance would be lower than Institutional Class or
            Administrative Class performance because of the higher sales
            charges and/or expenses paid by Class A shares. The returns in the
            bar chart and the information to its right do not reflect the
            impact of sales charges (loads). If they did, the returns would be
            lower than those shown. Unlike the bar chart, performance figures
            for Class A shares in the Average Annual Total Returns table
            reflect the impact of sales charges. For periods prior to the
            inception of Institutional Class and Administrative Class shares
            (2/26/99), the Average Annual Total Returns table also shows
            estimated historical performance for those classes based on the
            performance of the Portfolio's Class A shares. The Class A
            performance has been adjusted to reflect that there are no sales
            charges and lower distribution and/or service (12b-1) fees (if
            any), administrative fees and other expenses paid by Institutional
            Class and Administrative Class shares. Past performance is no
            guarantee of future results.

            (1) The Administrative Fees for the Portfolio do not reflect a
                voluntary fee waiver of 0.05% currently in effect. While the
                fee waiver is in effect, actual Administrative Fees will be
                0.10%, and Total Annual Portfolio Operating Expenses are
                estimated to be as follows: Institutional Class - 0.88%;
                Administrative Class - 1.13%.
            (2) Based on estimated expenses for the current fiscal year.
                Underlying Fund Expenses for the Portfolio are estimated based
                upon a recent allocation of the Portfolio's assets among
                Underlying Funds and upon the total annual operating expenses
                of Institutional Class shares of these Underlying Funds. For a
                listing of the expenses associated with each Underlying Fund,
                please see "Management of the Portfolios--Underlying Fund
                Expenses." Total Annual Portfolio Operating Expenses and the
                Examples set forth below are based on estimates of the
                Underlying Fund Expenses the Portfolio will incur. Actual
                Underlying Fund Expenses for the Portfolio are expected to
                vary with changes in the allocation of the Portfolio's assets,
                and may be higher or lower than those shown above.

            Examples. The Examples are intended to help you compare the cost
            of investing in Institutional Class or Administrative Class shares
            of the Portfolio 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 the
            Portfolio'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 Portfolio seeks to achieve its investment objective by
            normally investing approximately 60% (within a range of 50%--70%)
            of its assets in Underlying Stock Funds and approximately 40%
            (within a range of 30%--50%) of its assets in Underlying Bond
            Funds. The Portfolio invests all of its assets in shares of the
            Underlying Funds and does not invest directly in stocks or bonds
            of other issuers. Please see "Asset Allocation Strategies" on page
            3 for a summary of how the Asset Allocation Committee allocates
            and reallocates the Portfolio's assets among particular Underlying
            Funds.

              The Portfolio may concentrate investments in a particular
            Underlying Fund by investing more than 25% of its assets in that
            Fund.

              Based on the Portfolio's equity/fixed income allocation
            strategy, it might be suitable for an investor with a medium-range
            time horizon who seeks a balance of long-term capital appreciation
            potential and income and has a medium tolerance for risk and
            volatility.

Principal
Risks       Allocation Risk The Portfolio's investment performance depends
            upon how its assets are allocated and reallocated among particular
            Underlying Funds. A principal risk of investing in the Portfolio
            is that the Asset Allocation Committee's allocation techniques and
            decisions and/or PIMCO Advisors' selection of Underlying Funds
            will not produce the desired results, and therefore the Portfolio
            may not achieve its investment objective.

            Underlying Fund Risks The value of your investment in the
            Portfolio is directly related to the investment performance of the
            Underlying Funds in which it invests. Therefore, the principal
            risks of investing in the Portfolio are closely related to the
            principal risks associated with the Underlying Funds and their
            investments. Because the Portfolio's allocation among the
            Underlying Funds will vary, an investment may be subject to any
            and all of these risks at different times and to different
            degrees.

            Among the principal risks of the Underlying Funds, which could
            adversely affect the net asset value, yield and total return of
            the Portfolio, are:

              .Market Risk          .Credit Risk        .Emerging Markets
              .Issuer Risk          .High Yield Risk    Risk
              .Value Securities     .Mortgage Risk      .Currency Risk
               Risk                 .Liquidity Risk     .Focused Investment
              .Growth Securities    .Derivatives Risk    Risk
               Risk                 .Foreign Investment .Leveraging Risk
              .Smaller Company       Risk               .Management Risk
               Risk
              .Interest Rate Risk

            Please see "Summary of Principal Risks" following the Portfolio
            Summaries for a description of these and other risks associated
            with the Underlying Funds and an investment in the Portfolio.

Performance The following shows summary performance information for the
Information Portfolio in a bar chart and an Average Annual Total Returns
            table. The information provides some indication of the risks of
            investing in the Portfolio by showing changes in its performance
            from year to year and by showing how the Portfolio's average
            annual returns compare with the returns of broad-based securities
            market indices and an index of mutual funds. The bar chart, the
            information to its right and the Average Annual Total Returns
            table show performance of the Portfolio's Class A shares, which
            are offered in a different prospectus. This is because the
            Portfolio has not offered Institutional Class or Administrative
            Class shares for a full calendar year. Although Class A,
            Institutional Class and Administrative Class shares would have
            similar returns (because all the Portfolio's shares represent
            interests in the same portfolio of securities), Class A
            performance would be lower than Institutional Class or
            Administrative Class performance because of the higher sales
            charges and/or expenses paid by Class A shares. The returns in the
            bar chart and the information to its right do not reflect the
            impact of sales charges (loads). If they did, the returns would be
            lower than those shown. Unlike the bar chart, performance figures
            for Class A shares in the Average Annual Total Returns table
            reflect the impact of sales charges. For periods prior to the
            inception of Institutional Class and Administrative Class shares
            (2/26/99), the Average Annual Total Returns table also shows
            estimated historical performance for those classes based on the
            performance of the Portfolio's Class A shares. The Class A
            performance has been adjusted to reflect that there are no sales
            charges and lower distribution and/or service (12b-1) fees (if
            any), administrative fees and other expenses paid by Institutional
            Class and Administrative Class shares. Past performance is no
            guarantee of future results.

                 0.10%, and Total Annual Portfolio Operating Expenses are
                 estimated to be as follows: Institutional Class - 0.77%;

            (2)  Based on estimated expenses for the current fiscal year.
                 Underlying Fund Expenses for the Portfolio are estimated
                 based upon a recent allocation of the Portfolio's assets
                 among Underlying Funds and upon the total annual operating
                 expenses of Institutional Class shares of these Underlying
                 Funds. For a listing of the expenses associated with each
                 Underlying Fund, please see "Management of the Portfolios--
                 Underlying Fund Expenses." Total Annual Portfolio Operating
                 Expenses and the Examples set forth below are based on
                 estimates of the Underlying Fund Expenses the Portfolio will
                 incur. Actual Underlying Fund Expenses for the Portfolio are
                 expected to vary with changes in the allocation of the
                 Portfolio's assets, and may be higher or lower than those
                 shown above.

            Examples. The Examples are intended to help you compare the cost
            of investing in Institutional Class or Administrative Class shares
            of the Portfolio 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 the
            Portfolio'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 Portfolio seeks to achieve its investment objective by
            normally investing approximately 30% (within a range of 25%--35%)
            of its assets in Underlying Stock Funds and approximately 70%
            (within a range of 65%--75%) of its assets in Underlying Bond
            Funds. The Portfolio invests all of its assets in shares of the
            Underlying Funds and does not invest directly in stocks or bonds
            of other issuers. Please see "Asset Allocation Strategies" on page
            3 for a summary of how the Asset Allocation Committee allocates
            and reallocates the Portfolio's assets among particular Underlying
            Funds.

              The Portfolio may concentrate investments in a particular
            Underlying Fund by investing more than 25% of its assets in that
            Fund.

              Based on the Portfolio's equity/fixed income allocation
            strategy, it might be suitable for an investor with a shorter time
            horizon who seeks a higher level of income combined with some
            potential for long-term capital appreciation and has a lower
            tolerance for risk and volatility.

--------------------------------------------------------------------------------
Principal
Risks       Allocation Risk The Portfolio's investment performance depends
            upon how its assets are allocated and reallocated among particular
            Underlying Funds. A principal risk of investing in the Portfolio
            is that the Asset Allocation Committee's allocation techniques and
            decisions and/or PIMCO Advisors' selection of Underlying Funds
            will not produce the desired results, and therefore the Portfolio
            may not achieve its investment objective.

            Underlying Fund Risks The value of your investment in the
            Portfolio is directly related to the investment performance of the
            Underlying Funds in which it invests. Therefore, the principal
            risks of investing in the Portfolio are closely related to the
            principal risks associated with the Underlying Funds and their
            investments. Because the Portfolio's allocation among the
            Underlying Funds will vary, an investment may be subject to any
            and all of these risks at different times and to different
            degrees.

            Among the principal risks of the Underlying Funds, which could
            adversely affect the net asset value, yield and total return of
            the Portfolio, are:

              . Interest Rate    . Value Securities     . Emerging Markets
                Risk               Risk                   Risk

--------------------------------------------------------------------------------
Performance The following shows summary performance information for the
Information Portfolio in a bar chart and an Average Annual Total Returns
            table. The information provides some indication of the risks of
            investing in the Portfolio by showing changes in its performance
            from year to year and by showing how the Portfolio's average
            annual returns compare with the returns of broad-based securities
            market indices and an index of mutual funds. The bar chart, the
            information to its right and the Average Annual Total Returns
            table show performance of the Portfolio's Class A shares, which
            are offered in a different prospectus. This is because the
            Portfolio has not offered Institutional Class or Administrative
            Class shares for a full calendar year. Although Class A,
            Institutional Class and Administrative Class shares would have
            similar returns (because all the Portfolio's shares represent
            interests in the same portfolio of securities), Class A
            performance would be lower than Institutional Class or
            Administrative Class performance because of the higher sales
            charges and/or expenses paid by Class A shares. The returns in the
            bar chart and the information to its right do not reflect the
            impact of sales charges (loads). If they did, the returns would be
            lower than those shown. Unlike the bar chart, performance figures
            for Class A shares in the Average Annual Total Returns table
            reflect the impact of sales charges. For periods prior to the
            inception of Institutional Class and Administrative Class shares
            (2/26/99), the Average Annual Total Returns table also shows
            estimated historical performance for those classes based on the
            performance of the Portfolio's Class A shares. The Class A
            performance has been adjusted to reflect that there are no sales
            charges and lower distribution and/or service (12b-1) fees (if
            any), administrative fees and other expenses paid by Institutional
            Class and Administrative Class shares. Past performance is no
            guarantee of future results.

                 expenses of Institutional Class shares of these Underlying
                 Funds. For a listing of the expenses associated with each
                 Underlying Fund, please see "Management of the Portfolios--
                 Underlying Fund Expenses." Total Annual Portfolio Operating
                 Expenses and the Examples set forth below are based on
                 estimates of the Underlying Fund Expenses the Portfolio will
                 incur. Actual Underlying Fund Expenses for the Portfolio are
                 expected to vary with changes in the allocation of the
                 Portfolio's assets, and may be higher or lower than those
                 shown above.

            Examples. The Examples are intended to help you compare the cost
            of investing in Institutional Class or Administrative Class shares
            of the Portfolio 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 the
            Portfolio'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 an investment in a Portfolio changes with the values
            of that Portfolio's investments in the Underlying Funds. Many
            factors can affect those values. The factors that are most likely
            to have a material effect on a particular Portfolio's investments
            as a whole are called "principal risks." The principal risks of
            each Portfolio are identified in the Portfolio Summaries beginning
            on page 5 and are summarized in this section. There is no
            guarantee that a Portfolio will be able to achieve its investment
            objective.

            Allocation Risk

            Each Portfolio's investment performance depends upon how its
            assets are allocated and reallocated among particular Underlying
            Funds according to the Portfolio's equity/fixed income allocation
            targets and ranges. A principal risk of investing in each
            Portfolio is that PIMCO Advisors' Asset Allocation Committee will
            make less than optimal or poor asset allocation decisions and/or
            that PIMCO Advisors will make less than optimal decisions in
            selecting the Underlying Funds in which the Portfolios invest. The
            Committee attempts to identify asset classes and sub-classes
            represented by the Underlying Funds that will provide consistent,
            quality performance for the Portfolios, but there is no guarantee
            that the Committee's allocation techniques will produce the
            desired results. It is possible that the Committee and/or PIMCO
            Advisors will focus on Underlying Funds that perform poorly or
            underperform other available Funds under various market
            conditions. You could lose money on your investment in a Portfolio
            as a result of these allocation decisions.

            Underlying Fund Risks

            Because each Portfolio invests all of its assets in Underlying
            Funds, the risks associated with investing in the Portfolios are
            closely related to the risks associated with the securities and
            other investments held by the Underlying Funds. The ability of a
            Portfolio to achieve its investment objective will depend upon the
            ability of the Underlying Funds to achieve their objectives. There
            can be no assurance that the investment objective of any
            Underlying Fund will be achieved.

              Each Portfolio's net asset value will fluctuate in response to
            changes in the net asset values of the Underlying Funds in which
            it invests. The extent to which the investment performance and
            risks associated with a particular Portfolio correlate to those of
            a particular Underlying Fund will depend upon the extent to which
            the Portfolio's assets are allocated from time to time for
            investment in the Underlying Fund, which will vary. A Portfolio's
            investment in a particular Underlying Fund may and in some cases
            is expected to exceed 25% of its assets. To the extent that a
            Portfolio invests a significant portion of its assets in an
            Underlying Fund, it will be particularly sensitive to the risks
            associated with that Fund.

              The following summarizes principal risks associated with
            investments in the Underlying Funds and, indirectly, with your
            investment in a Portfolio. Each Underlying Fund may be subject to
            additional principal risks other than those described below
            because the types of investments made by an Underlying Fund can
            change over time. The summary is not intended to be exhaustive.
            For a more complete description of these risks and the securities
            and investment techniques used by the Underlying Funds, please
            refer to the Statement of Additional Information and the
            Underlying Fund prospectuses, which are incorporated herein by
            reference and are available free of charge by telephoning the
            Trust at 1-800-927-4648.

Market      The market price of securities owned by an Underlying Fund may go
Risk        up or down, 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 and the Underlying Stock
            Funds are particularly sensitive to these market risks.

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

                                                                   Prospectus 14

            securities the Fund's portfolio manager believes are selling at a
            price lower than their true value. PIMCO Equity Income,
            Renaissance, Value, Small-Cap Value, Capital Appreciation, Mid-Cap
            and Micro-Cap Funds and PIMCO Allianz Select International Fund
            place particular emphasis on value securities. Companies that
            issue value securities may have experienced adverse business
            developments or may be subject to special risks that have caused
            their securities to be out of favor. If a portfolio manager's
            assessment of a company's prospects is wrong, or if the market
            does not recognize the value of the company, the price of its
            securities may decline or may not approach the value that the
            portfolio manager anticipates.

Growth
Securities  Each Underlying Stock Fund may invest in equity securities of
Risk        companies that its portfolio manager believes will experience
            relatively rapid earnings growth. PIMCO Growth, Target,
            Opportunity, Capital Appreciation, Mid-Cap, Micro-Cap and
            Innovation Funds and PIMCO Allianz Select International Fund place
            particular emphasis on growth securities. Growth securities
            typically trade at higher multiples of current earnings than other
            securities. Therefore, the values of growth securities may be more
            sensitive to changes in current or expected earnings than the
            values of other securities.

Smaller
Company     The general risks associated with equity securities and liquidity
Risk        risk are particularly pronounced for securities of companies with
            market capitalizations that are small compared to other publicly
            traded companies. These companies may have limited product lines,
            markets or financial resources or they may depend on a few key
            employees. Securities of smaller companies may trade less
            frequently and in lesser volume than more widely held securities
            and their values may fluctuate more sharply than other securities.
            They may also trade in the over-the-counter market or on a
            regional exchange, or may otherwise have limited liquidity. PIMCO
            Opportunity, Micro-Cap, Small-Cap Value and Innovation Funds
            generally have substantial exposure to this risk. PIMCO Target and
            Mid-Cap Funds and PIMCO Allianz Select International Fund also
            have significant exposure to this risk because they invest
            substantial assets in companies with medium-sized market
            capitalizations, which are smaller and generally less-seasoned
            than the largest companies. Smaller company risk also applies to
            fixed income securities issued by smaller companies and may affect
            certain investments of the Underlying Bond Funds.

Liquidity
Risk        Many of the Underlying Funds are subject to liquidity risk.
            Liquidity risk exists when particular investments are difficult to
            purchase or sell, possibly preventing a Fund from selling out of
            these illiquid securities at an advantageous time or price.
            Underlying Funds with principal investment strategies that involve
            securities of companies with smaller market capitalizations,
            foreign securities, derivatives or securities with substantial
            market and/or credit risk tend to have the greatest exposure to
            liquidity risk.

Derivatives Many of the Underlying Funds may, but are not required to, use a
Risk        number of derivative instruments for risk management purposes or
            as part of their 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. An
            Underlying 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. Also, an Underlying Fund's 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 the various derivative instruments in which the
            Underlying Funds may invest and the risks associated with each
            instrument is included in the Underlying Fund prospectuses and 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 Underlying 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.

              Leveraging 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 an Underlying 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 leveraging risk, the Underlying Funds
            observe asset segregation requirements to cover their 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 an
            Underlying 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 considerations.

              Market and Other Risks Like most other investments, derivative
            instruments are subject to the general risk that the market value
            of the instrument will change in a way detrimental to an
            Underlying 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 an Underlying
            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 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 investments of an
            Underlying Fund. An Underlying 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 an Underlying 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, an Underlying Fund's use
            of derivatives may also cause the Fund to realize higher amounts
            of short-term capital gains (taxed at ordinary income tax rates
            when distributed to shareholders who are individuals) than if the
            Fund had not used such instruments.

Foreign
(non-       Many Underlying Funds (in particular, PIMCO International,
U.S.)       Structured Emerging Markets, Tax-Efficient Structured Emerging
Investment  Markets, Global Bond, Foreign Bond and Emerging Markets Bond Funds
Risk        and PIMCO Allianz Select International Fund) invest in securities
            of foreign issuers, securities traded principally in securities
            markets outside the United States and/or securities denominated in
            foreign currencies (together, "foreign securities"). These Funds
            may experience more rapid and extreme changes in value than Funds
            that invest exclusively in securities of U.S. issuers or
            securities that trade exclusively in U.S. markets.

              The securities markets of many foreign countries are relatively
            small, with a limited number of companies representing a small
            number of industries. Foreign securities often trade with less
            frequency and volume than domestic securities and therefore may
            exhibit greater price volatility. 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 an Underlying 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. To
            the extent that an Underlying Fund invests a significant portion
            of its assets in a narrowly defined geographic area such as
            Eastern Europe, South Africa or Asia, the Fund will generally have
            more exposure to regional economic risks associated with foreign
            investments. Adverse conditions in certain regions (such as
            Southeast Asia) can also adversely affect securities of other
            countries whose economies appear to be unrelated. In addition,
            special U.S. tax considerations may apply to an Underlying Fund's
            investment in foreign securities.


                                                                   Prospectus 16
<PAGE>

              Certain Underlying Bond Funds 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    Certain Underlying Funds (in particular, PIMCO Structured Emerging
Markets     Markets, Tax-Efficient Structured Emerging Markets and Emerging
Risk        Markets Bond Funds) may invest in the securities of issuers based
            in countries with developing or "emerging market" 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
Risk        Many Underlying Funds may invest directly in foreign currencies or
            in securities that trade in, or receive revenues in, foreign
            currencies. To the extent that they do so, these Funds 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. PIMCO Global Bond, Foreign Bond, Emerging Markets Bond,
            International, Structured Emerging Markets and Tax-Efficient
            Structured Emerging Markets Funds and PIMCO Allianz Select
            International Fund are particularly sensitive to currency risk.
            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. For example, uncertainty
            surrounds the introduction of the euro (a common currency unit for
            the European Union) and its effect on the value of European
            currencies as well as securities denominated in local European
            currencies. These and other currencies in which Underlying Fund
            assets are denominated may be devalued against the U.S. dollar,
            resulting in a loss to such Funds.

Focused
Investment  Focusing Fund investments in a small number of issuers, industries
Risk        or foreign currencies increases risk. PIMCO Global Bond, Foreign
            Bond and Emerging Markets Bond Funds are "non-diversified," which
            means that they invest in a smaller number of issuers than
            diversified mutual funds. Other Underlying Funds also normally
            invest in a relatively small number of issuers. In addition, many
            Underlying Bond Funds may invest a substantial portion of their
            assets in the bonds of similar projects or from issuers in the
            same state. To the extent that they focus their investments, the
            Underlying Funds may have more risk because changes in the value
            of a single security or the impact of a single economic, political
            or regulatory occurrence may have a greater adverse impact on the
            Underlying Fund's net asset value. Some of those investments also
            may present substantial credit or other risks. PIMCO
            International, Structured Emerging Markets, Tax-Efficient
            Structured Emerging Markets, Global Bond, Foreign Bond and
            Emerging Markets Bond Funds and PIMCO Allianz Select International
            Fund may be subject to increased risk to the extent they focus
            their assets in securities denominated in a particular foreign
            currency or in a narrowly defined geographic area outside the
            U.S., because companies in these areas may share common
            characteristics and are often subject to similar business risks
            and regulatory burdens, and their securities may react similarly
            to economic, market, political or other developments. Similarly,
            PIMCO Innovation Fund is vulnerable to events affecting companies
            which use innovative technologies to gain a strategic, competitive
            advantage in their industry and companies that provide and service
            those technologies because it normally concentrates its
            investments in those companies. Also, the Underlying Funds may
            from time to time have greater risk to the extent they invest a
            substantial portion of their assets in companies in related
            industries such as "technology" or "financial and business
            services," which may share common characteristics, are often
            subject to similar business risks and regulatory burdens, and
            whose securities may react similarly to economic, market,
            political or other developments.

             Although each Portfolio normally invests in a number of different
            Underlying Funds, to the extent that a Portfolio concentrates a
            significant portion of its assets in a single Underlying Fund, it
            will be particularly sensitive to the risks associated with that
            Fund and any investments in which that Fund concentrates.

Leveraging
Risk        Leverage, including borrowing, will cause the value of an
            Underlying  Fund's shares to be more volatile that if the Fund did
            not use leverage. This is because leverage tends to exaggerate the
            effect of any increase or decrease in the value of a Fund's
            portfolio securities. Certain Underlying Funds may engage in
            transactions or purchase instruments that give rise to forms of
            leverage. Such transactions and instruments may include, among
            others, the use of reverse repurchase agreements and other
            borrowings, the investment of collateral from loans of portfolio
            securities, or the use of when-issued, delayed-delivery or forward
            commitment transactions. An Underlying Fund's use of derivatives
            may also involve leverage. The use of leverage may also cause an
            Underlying Fund to liquidate portfolio positions when it may not
            be advantageous to do so in order to satisfy its obligations or to
            meet segregation requirements.

Interest    All of the Underlying Funds that invest in fixed income
Rate Risk   securities, and particularly the Underlying Bond Funds, are
            subject to interest rate risk. Changes in the market values of
            fixed income securities are largely a function of changes in the
            current level of interest rates. The value of an Underlying Fund's
            investments in fixed income securities will typically change as
            the level of interest rates fluctuate. During periods of declining
            interest rates, the value of fixed income securities generally
            rise. Conversely, during periods of rising interest rates, the
            value of fixed income securities generally decline.

             "Duration" is one 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. Securities with longer
            durations tend to be more sensitive to changes in interest rates,
            usually making them more volatile than securities with shorter
            durations. Accordingly, Underlying Bond Funds with longer average
            portfolio durations (e.g., PIMCO Long-Term U.S. Government Fund)
            will generally be more sensitive to changes in interest rates than
            Funds with shorter average portfolio durations (e.g., PIMCO Money
            Market, Short-Term and Low Duration Funds). Also, some portfolios
            (e.g., those with mortgage-backed and other prepayable securities)
            have changing durations and may have increasing durations
            precisely when that is least advantageous (i.e., when interest
            rates are rising).

             Many Underlying Funds, including most of the Underlying Bond
            Funds, may invest in securities that are particularly sensitive to
            fluctuations in prevailing interest rates and have relatively high
            levels of interest rate risk. These include various mortgage-
            related securities (for instance, the interest-only or "IO" class
            of a stripped mortgage-backed security) and "zero coupon"
            securities (fixed income securities, including certain U.S.
            Government securities, that do not make periodic interest payments
            and are purchased at a discount from their value at maturity).

Credit      All of the Underlying Funds are subject to credit risk. This is
Risk        the risk that the issuer or the guarantor of a fixed income
            security, or the counterparty to a derivatives contract,
            repurchase agreement or a loan of portfolio securities, will be
            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
            reflecting in credit ratings provided by rating agencies such as
            Moody's Investors Service, Inc. ("Moody's") and Standard & Poor's
            Ratings Services ("S&P").

             The Underlying Funds that invest in fixed income securities
            (particularly the Underlying Bond Funds) are subject to varying
            degrees of risk that the issuers of the securities will have their
            credit ratings downgraded or will default, potentially reducing
            the Underlying Fund's share price and income level. Nearly all
            fixed income securities are subject to some credit risk, whether
            the issuers of the securities are corporations, states and local
            governments or foreign governments. Even certain U.S. Government
            securities are subject to credit risk.

High
Yield       High yield securities (commonly known as "junk bonds") are fixed
Risk        income securities rated lower than Baa by Moody's or BBB by S&P,
            or unrated securities determined to be of comparable quality.
            Underlying Bond Funds which invest in high yield securities (in
            particular, PIMCO High Yield and Emerging Markets Bond Funds) may
            be subject to greater levels of interest rate, credit and
            liquidity risk than Funds that invest exclusively in higher
            quality fixed income securities (e.g., PIMCO Money Market and
            Long-Term U.S. Government Funds). These securities are considered
            predominately speculative with respect to the issuer's continuing
            ability to make principal and interest payments (credit risk).
            These securities may also be more susceptible to real or perceived
            adverse economic and competitive industry conditions than higher
            quality fixed income securities. An economic downturn or period of
            rising interest rates could adversely affect the market for these
            securities and reduce an Underlying Bond Fund's ability to sell
            them (liquidity risk).

Mortgage    Most of the Underlying Bond Funds may invest in mortgage-related
Risk        securities. 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, an Underlying Fund that holds mortgage-related securities
            may exhibit additional volatility. This is sometimes referred to
            as extension risk. In addition, mortgage-related securities may
            involve special risks relating to unanticipated rates of
            prepayment on the mortgages underlying the securities. This is
            sometimes referred to as prepayment risk. Declining interest rates
            may tend to increase prepayments, and these prepayments would have
            to be reinvested at the then-prevailing lower interest rates.
            Therefore, an Underlying Fund that holds mortgage-related
            securities may have less potential for capital appreciation during
            periods of declining interest rates than Funds that invest in
            other types of fixed income securities of similar maturities.

                                                                  Prospectus 18

Management
Risk        Each Underlying Fund is subject to management risk because it is
            an actively managed investment portfolio. PIMCO Advisors, Pacific
            Investment Management Company LLC ("Pacific Investment Management
            Company"), and the sub-advisers and individual portfolio managers
            of the Underlying Funds will apply investment techniques and risk
            analyses in making investment decisions for the Funds, but there
            can be no guarantee that they will produce the desired results.

A Note on
PIMCO       Each Portfolio may invest in PIMCO StocksPLUS Fund. While the
StocksPLUS  investment objective of that Fund is to achieve a total return
Fund        which exceeds the total return performance of the S&P 500 Index,
            it does so by investing substantially all of its assets in a
            combination of equity-based (S&P 500 Index) derivative
            instruments, backed by a portfolio of fixed income securities.
            Consequently, the risks of investing in the Fund include
            derivatives risk and the risks generally associated with the
            Underlying Bond Funds. To the extent that the Fund invests in S&P
            500 Index derivatives backed by a portfolio of fixed income
            securities, under certain conditions, generally in a market where
            the value of both S&P 500 Index derivatives and fixed income
            securities are declining, the Fund may experience greater losses
            than would be the case if it were to invest directly in a
            portfolio of S&P 500 Index stocks.

            Investment Objectives and Principal Investment Strategies

            The investment objective and principal investment strategies of
            each Portfolio are described below. There can be no assurance that
            the investment objective of any Portfolio will be achieved.
            Because the market value of each Portfolio's investments will
            change, the net asset value per share of each Portfolio will also
            vary.

             The Portfolios are intended for investors who prefer to have
            their asset allocation decisions made by professional money
            managers. Each Portfolio seeks to achieve its investment objective
            by investing within specified equity and fixed income ranges among
            the Underlying Funds. Each Underlying Fund is a series of the
            Trust or PIMCO Funds: Pacific Investment Management Series and is
            managed by PIMCO Advisors and/or its affiliates.

Portfolio   90/10 Portfolio seeks long-term capital appreciation. Under normal
Descriptionsconditions, approximately 90% of the Portfolio's assets will be
            allocated among Underlying Stock Funds and 10% among Underlying
            Bond Funds.

            60/40 Portfolio seeks long-term capital appreciation and current
            income. Under normal conditions, approximately 60% of the
            Portfolio's assets will be allocated among Underlying Stock Funds
            and 40% among Underlying Bond Funds.

            30/70 Portfolio seeks current income. Long-term capital
            appreciation is a secondary objective. Under normal conditions,
            approximately 30% of the Portfolio's assets will be allocated
            among Underlying Stock Funds and 70% among Underlying Bond Funds.

             PIMCO Advisors serves as the investment adviser to the Portfolios
            and selects the Underlying Funds in which the Portfolios may
            invest. PIMCO Advisors' Asset Allocation Committee determines how
            each Portfolio allocates and reallocates its assets among the
            Underlying Funds selected by PIMCO Advisors according to the
            Portfolio's equity/fixed income allocation targets and ranges.
            Please see "Asset Allocation Strategies" in the Summary
            Information section above for a description of the allocation
            strategies and techniques used by the Committee. The table below
            illustrates the equity and fixed income allocation targets and
            typical ranges for each Portfolio under normal market conditions.

              Each Portfolio invests all of its assets in Underlying Funds and
            may invest in any or all of the Funds. However, it is expected
            that a Portfolio will invest in only some of the Underlying Funds
            at any particular time. A Portfolio's investment in a particular
            Underlying Fund may exceed 25% of the Portfolio's total assets. To
            the extent that a Portfolio invests a significant portion of its
            assets in an Underlying Fund, it will be particularly sensitive to
            the risks associated with that Fund. The particular Underlying
            Funds in which each Portfolio may invest, the equity and fixed
            income allocation targets and ranges specified above, and the
            percentage of each Portfolio's assets invested from time to time
            in any Underlying Fund or combination of Funds may be changed from
            time to time without the approval of the Portfolio's shareholders.
            Each Portfolio is also subject to certain investment restrictions
            that are described under "Investment Restrictions" in the
            Statement of Additional Information.

                                                                   Prospectus 20

Temporary   In response to unfavorable market and other conditions, each
Defensive   Portfolio may invest up to 100% of its assets in PIMCO Money
Strategies  Market Fund (and may deviate from its asset allocation range) for
            temporary defensive purposes. A Portfolio may also borrow money
            for temporary or emergency purposes. These temporary strategies
            would be inconsistent with the Portfolio's investment objective
            and principal investment strategies and may adversely affect the
            Portfolio's ability to achieve its investment objective.

Portfolio   A change in the securities held by a Portfolio is known as
Turnover    "portfolio turnover." Because PIMCO Advisors does not expect to
            reallocate the Portfolios' assets among the Underlying Funds on a
            frequent basis, the portfolio turnover rates for the Portfolios
            are expected to be modest (i.e., less than 25%) in comparison to
            most mutual funds. However, the Portfolios' indirectly bear the
            expenses associated with portfolio turnover of the Underlying
            Funds, a number of which have fairly high portfolio turnover rates
            (i.e., in excess of 100%). High portfolio turnover involves
            correspondingly greater expenses to an Underlying Fund, including
            brokerage commissions or dealer mark-ups and other transaction
            costs on the sale of securities and reinvestments in other
            securities. Shareholders in the Portfolios may also bear expenses
            directly or indirectly through sales of securities held by the
            Portfolios and the Underlying Funds which result in realization of
            taxable capital gains. To the extent such gains relate to
            securities held for twelve months or less, such gains will be
            short-term capital gains taxed at ordinary income tax rates when
            distributed to shareholders who are individuals. The trading costs
            and tax effects associated with portfolio turnover may adversely
            affect a Portfolio's performance and the return to shareholders.


Changes     The investment objective, the equity/fixed income allocation
in          targets and ranges, and, unless otherwise noted, other investment
Investment  policies of each Portfolio described in this Prospectus may be
Objectives  changed by the Board of Trustees without shareholder approval. If
and         there is a change in a Portfolio's investment objective,
Policies    allocation target or range, or other investment policies,
            shareholders should consider whether the Portfolio remains an
            appropriate investment in light of their then current financial
            positions and needs.

                                                                   Prospectus 22

            Underlying Funds

            Each Portfolio invests all of its assets in Underlying Funds.
            Accordingly, each Portfolio's investment performance depends upon
            a favorable allocation among the Underlying Funds as well as the
            ability of the Underlying Funds to achieve their objectives. There
            can be no assurance that the investment objective of any
            Underlying Fund will be achieved. Shares of the Underlying Funds
            are not offered in this Prospectus.

Underlying  The investment objective of each Underlying Bond Fund (except as
Bond        provided below) is to seek to realize maximum total return,
Funds       consistent with preservation of capital and prudent investment
            management. The "total return" sought by most of the Underlying
            Bond Funds will consist 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. The investment
            objective of PIMCO Real Return Bond Fund is to seek to realize
            maximum real return, consistent with preservation of real capital
            and prudent investment management. "Real return" is a measure of
            the change in purchasing power of money invested in a particular
            investment after adjusting for inflation. The investment objective
            of each of PIMCO Money Market Fund and PIMCO Short-Term Fund is to
            seek to obtain maximum current income, consistent with
            preservation of capital and daily liquidity. PIMCO Money Market
            Fund also attempts to maintain a stable net asset value of $1.00
            per share, although there can be no assurance that it will be
            successful in doing so.

             The following provides a concise description of the main
            investments of and other information relating to each Underlying
            Bond Fund. For a complete description of these Funds, please see

            These and the other types of securities and investment techniques
            used by the Underlying Funds all have attendant risks. The
            Portfolios are indirectly subject to some or all of these risks to
            varying degrees because they invest all of their assets in the
            Underlying Funds. For further information concerning the
            investment practices of and risks associated with the Underlying
            Funds, please see "Investment Objectives and Policies" in the

Additional
Underlying Funds
            In addition to the Funds listed above, a Portfolio may invest in
            additional Underlying Funds, including those that may become
            available for investment in the future, at the discretion of PIMCO
            Advisors and without shareholder approval.

            Other Risk Information

Potential   PIMCO Advisors has broad discretion to allocate and reallocate the
Conflicts   Portfolios' assets among the Underlying Funds consistent with the
of          Portfolios' investment objectives and policies and asset
Interest    allocation targets and ranges. Although PIMCO Advisors does not
            charge an investment advisory fee for its asset allocation
            services, PIMCO Advisors and its affiliates indirectly receive
            fees (including investment advisory and administrative fees) from
            the Underlying Funds in which the Portfolios invest. In this
            regard, PIMCO Advisors has a financial incentive to invest a
            Portfolio's assets in Underlying Funds with higher fees than other
            Funds, even if it believes that alternate investments would better
            serve the Portfolio's investment program. PIMCO Advisors is
            legally obligated to disregard that incentive in making asset
            allocation decisions for the Portfolios. The Trustees and officers
            of the Trust may also have conflicting interests in fulfilling
            their fiduciary duties to both the Portfolios and the Underlying
            Funds of the Trust.

Investment
Adviser
and
Administrator
            PIMCO Advisors serves as the investment adviser and the
            administrator (serving in its capacity as administrator, the
            "Administrator") for the Portfolios. Subject to the supervision of
            the Board of Trustees, PIMCO Advisors is responsible for managing,
            either directly or through others selected by it, the investment
            activities of the Portfolios and the Portfolios' business affairs
            and other administrative matters.

              PIMCO Advisors is located at 800 Newport Center Drive, Newport
            Beach, California 92660. Organized in 1987, PIMCO Advisors
            provides investment management and advisory services to private
            accounts of institutional and individual clients and to mutual
            funds. As of September 30, 2000, PIMCO Advisors and its subsidiary
            partnerships had approximately $272 billion in assets under
            management.

              PIMCO Advisors has retained its affiliate, Pacific Investment
            Management Company, to provide various administrative and other
            services required by the Portfolios in its capacity as sub-
            administrator. PIMCO Advisors and the sub-administrator may retain
            other affiliates to provide certain of these services.

Advisory    The Portfolios do not pay any fees to PIMCO Advisors under the
Fees        Trust's investment advisory agreement in return for the advisory
            and asset allocation services provided by PIMCO Advisors. The
            Portfolios do, however, indirectly pay their proportionate share
            of the advisory fees paid to PIMCO Advisors and Pacific Investment
            Management Company by the Underlying Funds in which the Portfolios
            invest. See "Underlying Fund Expenses" below.


Administrative
Fees
            Institutional Class and Administrative Class shareholders of each
            Portfolio pay an administrative fee to PIMCO Advisors, computed as
            a percentage of the Portfolio's assets attributable in the
            aggregate to those classes of shares. PIMCO Advisors, in turn,
            provides or procures administrative services for Institutional
            Class and Administrative Class shareholders and also bears the
            costs of most third-party services required by the Portfolios,
            including audit, custodial, portfolio accounting, legal, transfer
            agency and printing costs. The Portfolios do bear other expenses
            which are not covered under the administrative fee which may vary
            and affect the total level of expenses paid by Institutional Class
            and Administrative Class shareholders, such as brokerage fees,
            commissions and other transaction expenses, costs of borrowing
            money, including interest expenses, and fees and expenses of the
            Trust's disinterested Trustees.

              Each Portfolio pays monthly administrative fees to PIMCO
            Advisors at an annual rate of 0.15% based on the average daily net
            assets attributable in the aggregate to the Portfolio's
            Institutional Class and Administrative Class shares. In order to
            reduce expenses, PIMCO Advisors has voluntarily undertaken to
            waive a portion of the administrative fees it is entitled to
            receive for Institutional Class and Administrative Class shares of
            each Portfolio until further notice. As a result, while the waiver
            is in effect, each Portfolio will pay administrative fees to PIMCO
            Advisors at the annual rate of 0.10%, calculated in the manner
            specified above. The Portfolios also indirectly pay their
            proportionate share of the administrative fees charged by PIMCO
            Advisors and Pacific Investment Management Company to the
            Underlying Funds in which the Portfolios invest. See "Underlying
            Fund Expenses" below.

Underlying
Fund        The expenses associated with investing in a "fund of funds," such
Expenses    as the Portfolios, are generally higher than those for mutual
            funds that do not invest primarily in other mutual funds. This is
            because shareholders in a "fund of funds" indirectly pay a portion
            of the fees and expenses charged at the underlying fund level.

<PAGE>

              The Portfolios are structured in the following ways to lessen
            the impact of expenses incurred at the Underlying Fund level:

              .  The Portfolios do not pay any fees for asset allocation or
                 advisory services under the Trust's investment advisory
                 agreement.

              .  The Underlying Funds invest in Institutional Class shares of
                 the Underlying Funds, which are not subject to any sales
                 charges or 12b-1 fees.

              The following table summarizes the annual expenses borne by
            Institutional Class shareholders of the Underlying Funds (based on
            estimates for the current fiscal year). Because the Portfolios
            invest in Institutional Class shares of the Underlying Funds,
            shareholders of each Portfolio indirectly bear a proportionate
            share of these expenses, depending upon how the Portfolio's assets
            are allocated from time to time among the Underlying Funds. See
            "Fees and Expenses of the Portfolio" in each Portfolio Summary
            above.

Distributor
            The Trust's Distributor is PIMCO Funds Distributors LLC, a wholly
            owned subsidiary of PIMCO Advisors. The Distributor, located at
            2187 Atlantic Street, Stamford, CT 06902, is a broker-dealer
            registered with the Securities and Exchange Commission.

                                                                   Prospectus 28
<PAGE>

            Investment Options --
            Institutional Class and Administrative Class Shares

            The Trust offers investors Institutional Class and Administrative
            Class shares of the Portfolios in this Prospectus.

             The Trust does not charge any sales charges (loads) or other fees
            in connection with purchases, sales (redemptions) or exchanges of
            Institutional Class or Administrative Class shares. Administrative
            Class shares are generally subject to a higher level of operating
            expenses than Institutional Class shares due to the additional
            service and/or distribution fees paid by Administrative Class
            shares as described below. Therefore, Institutional Class shares
            will generally pay higher dividends and have a more favorable
            investment return than Administrative Class shares.

              . Service and Distribution (12b-1) Fees--Administrative Class
            Shares. The Trust has adopted an Administrative Services Plan and
            a Distribution Plan for the Administrative Class shares of each
            Portfolio. Each Plan has been adopted in accordance with the
            requirements of Rule 12b-1 under the Investment Company Act of
            1940 and is administered in accordance with that rule. However,
            shareholders do not have the voting rights set forth in Rule 12b-1
            with respect to the Administrative Services Plan.

             Each Plan allows the Portfolios to use their Administrative Class
            assets to reimburse financial intermediaries that provide services
            relating to Administrative Class shares. The Distribution Plan
            permits reimbursement for expenses in connection with the
            distribution and marketing of Administrative Class shares and/or
            the provision of shareholder services to Administrative Class
            shareholders. The Administrative Services Plan permits
            reimbursement for services in connection with the administration
            of plans or programs that use Administrative Class shares of the
            Portfolios as their funding medium and for related expenses.

             In combination, the Plans permit a Portfolio to make total
            reimbursements at an annual rate of up to 0.25% of the Portfolio's
            average daily net assets attributable to its Administrative Class
            shares. The same entity may not receive both distribution and
            administrative services fees with respect to the same
            Administrative Class assets, but may receive fees under each Plan
            with respect to separate assets. Because these fees are paid out
            of a Portfolio's Administrative Class assets on an ongoing basis,
            over time they will increase the cost of an investment in
            Administrative Class shares and may cost an investor more than
            other types of sales charges.

              . Arrangements with Service Agents. Institutional Class and
            Administrative Class shares of the Portfolios may 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
            and/or distribution fees paid with respect to Administrative Class
            shares. Service agents may impose additional or different
            conditions than the Trust on purchases, redemptions or exchanges
            of Portfolio shares by their customers. Service agents may also
            independently establish and charge their customers transaction
            fees, account fees and other amounts in connection with purchases,
            sales and redemptions of Portfolio shares in addition to any fees
            charged by the Trust. These additional fees may vary over time and
            would increase the cost of the customer's investment and lower
            investment returns. 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, redemptions and exchanges. Shareholders who
            are customers of service agents should consult their service
            agents for information regarding these fees and conditions.

            Purchases, Redemptions and Exchanges

            Investors may purchase Institutional Class and Administrative
Purchasing  Class shares of the Portfolios at the relevant net asset value
Shares      ("NAV") of that class without a sales charge or other fee.

             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 their
            customers' investments in the Portfolios.

             Administrative Class shares are offered primarily through
            employee benefit plan alliances, broker-dealers and other
            intermediaries, and each Portfolio pays service and/or
            distribution fees to these entities for services they provide to
            Administrative Class shareholders.

             Pension and profit-sharing plans, employee benefit trusts and
            employee benefit plan alliances and "wrap account" programs
            established with broker-dealers or financial intermediaries may
            purchase shares of either class only if the plan or program for
            which the shares are being acquired will maintain an omnibus or
            pooled account for each Portfolio and will not require a Portfolio
            to pay any type of administrative payment per participant account
            to any third party.

              . Investment Minimums. The minimum initial investment for shares
            of either class is $5 million, except that the minimum initial
            investment for a registered investment adviser purchasing
            Institutional Class shares for its clients through omnibus
            accounts is $250,000 per Portfolio. At the discretion of PIMCO
            Advisors, the minimum initial investment may be waived for
            Institutional or Administrative Class shares offered to clients of
            PIMCO Equity Advisors, PIMCO/Allianz International Advisors,
            Cadence, NFJ, Pacific Investment Management Company, Parametric
            and their affiliates, and to the benefit plans of PIMCO Advisors
            and its affiliates. In addition, the minimum initial investment
            does not apply to Institutional Class shares offered through fee-
            based programs sponsored and maintained by a registered broker-
            dealer and approved by the Distributor in which each investor pays
            an asset based fee at an annual rate of at least 0.50% of the
            assets in the account to a financial intermediary for investment
            advisory and/or administrative services.

             The Trust and the Distributor may waive the minimum initial
            investment for other categories of investors at their discretion.

             The investment minimums discussed in this section do not apply to
            participants in PIMCO Advisors Portfolio Strategies, a managed
            product sponsored by PIMCO Advisors.

              . Timing of Purchase Orders and Share Price Calculations. A
            purchase order received by the Trust's transfer agent, National
            Financial Data Services (the "Transfer Agent"), prior to the close
            of regular trading (normally 4:00 p.m., Eastern time) on the New
            York Stock Exchange, on a day the Trust is open for business,
            together with payment made in one of the ways described below,
            will be effected at that day's net asset value ("NAV"). An order
            received after the close of regular trading on the New York Stock
            Exchange will be effected at the NAV determined on the next
            business day. However, orders received by certain retirement plans
            and other financial intermediaries on a business day prior to the
            close of regular trading on the New York Stock Exchange and
            communicated to the Transfer Agent prior to 9:00 a.m., Eastern
            time, on the following business day will be effected at the NAV
            determined on the prior business day. The Trust is "open for
            business" on each day the New York Stock Exchange is open for
            trading, which excludes the following holidays: New Year's Day,
            Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
            Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
            Christmas Day. Purchase orders will be accepted only on days on
            which the Trust is open for business.

              . Initial Investment. Investors may open an account by
            completing and signing a Client Registration Application and
            mailing it to PIMCO Funds at 840 Newport Center Drive, Suite 300,
            Newport Beach, California 92660. A Client Registration Application
            may be obtained by calling 1-800-927-4648.

             Except as described below, an investor may purchase Institutional
            Class and Administrative Class shares only by wiring federal funds
            to the Transfer Agent, National Financial Data Services, 330 West
            9th Street, 4th Floor, Kansas City, Missouri 64105. Before wiring
            federal funds, the investor must telephone the Trust at 1-800-927-
            4648 to receive instructions for wire transfer and must provide
            the following information: name of authorized person, shareholder
            name, shareholder account number, name of Portfolio and share
            class, amount being wired, and wiring bank name.

                                                                   Prospectus 30
<PAGE>

             An investor may purchase shares without first wiring federal
            funds if the proceeds of the investment are derived from an
            advisory account the investor maintains with PIMCO Advisors or one
            of its affiliates, from surrender or other payment from an
            annuity, insurance, or other contract held by Pacific Life
            Insurance Company LLC, or from an investment by broker-dealers,
            institutional clients or other financial intermediaries which have
            established a shareholder servicing relationship with the Trust on
            behalf of their customers.

              . Additional Investments. An investor may purchase additional
            Institutional Class and Administrative Class shares of the
            Portfolios at any time by calling the Trust and wiring federal
            funds to the Transfer Agent as outlined above.

              . Other Purchase Information. Purchases of a Portfolio's
            Institutional Class and Administrative Class shares will be made
            in full and fractional shares. In the interest of economy and
            convenience, certificates for shares will not be issued.

             The Trust and the Distributor each reserves the right, in its
            sole discretion, to suspend the offering of shares of the
            Portfolios or to reject any purchase order, in whole or in part,
            when, in the judgment of management, such suspension or rejection
            is in the best interests of the Trust.

             An investor should invest in the Portfolios for long-term
            investment purposes only. The Trust and PIMCO Advisors each
            reserves the right to restrict purchases of Portfolio shares
            (including exchanges) when a pattern of frequent purchases and
            sales made in response to short-term fluctuations in share price
            appears evident. Notice of any such restrictions, if any, will
            vary according to the particular circumstances.

             Institutional Class and Administrative Class shares of the Trust
            may not be qualified or registered for sale in all states.
            Investors should inquire as to whether shares of a particular
            Portfolio are available for offer and sale in the investor's state
            of residence. Shares of the Trust may not be offered or sold in
            any state unless registered or qualified in that jurisdiction or
            unless an exemption from registration or qualification is
            available.

              . Retirement Plans. Shares of the Portfolios are available for
            purchase by retirement and savings plans, including Keogh plans,
            401(k) plans, 403(b) custodial accounts, and Individual Retirement
            Accounts. The administrator of a plan or employee benefits office
            can provide participants or employees with detailed information on
            how to participate in the plan and how to elect a Portfolio as an
            investment option. Participants in a retirement or savings plan
            may be permitted to elect different investment options, alter the
            amounts contributed to the plan, or change how contributions are
            allocated among investment options in accordance with the plan's
            specific provisions. The plan administrator or employee benefits
            office should be consulted for details. For questions about
            participant accounts, participants should contact their employee
            benefits office, the plan administrator, or the organization that
            provides recordkeeping services for the plan. Investors who
            purchase shares through retirement plans should be aware that plan
            administrators may aggregate purchase and redemption orders for
            participants in the plan. Therefore, there may be a delay between
            the time the investor places an order with the plan administrator
            and the time the order is forwarded to the Transfer Agent for
            execution.


Redeeming     . Redemptions by Mail. An investor may redeem (sell)
Shares      Institutional Class and Administrative Class shares by submitting
            a written request to PIMCO Funds at 840 Newport Center Drive,
            Suite 300, Newport Beach, California 92660. The redemption request
            should state the Portfolio from which the shares are to be
            redeemed, the class of shares, the number or dollar amount of the
            shares to be redeemed and the account number. The request must be
            signed exactly as the names of the registered owners appear on the
            Trust's account records, and the request must be signed by the
            minimum number of persons designated on the Client Registration
            Application that are required to effect a redemption.

              . Redemptions by Telephone or Other Wire Communication. An
            investor that elects this option on the Client Registration
            Application (or subsequently in writing) may request redemptions
            of shares by calling the Trust at 1-800-927-4648, by sending a
            facsimile to 1-949-725-6830, by sending an e-mail to
            [email protected], or by other means of wire
            communication. Investors should state the Portfolio and class from
            which the shares are to be redeemed, the number or dollar amount
            of the shares to be redeemed, the account number and the signature
            (which may be an electronic signature) of an authorized signatory.
            Redemption requests of an amount of $10 million or more may be
            initiated by telephone, wire or e-mail, but must be confirmed in
            writing by an authorized party prior to processing.

             In electing a telephone redemption, the investor authorizes
            Pacific Investment Management Company and the Transfer Agent to
            act on telephone instructions from any person representing himself
            to be the investor, and reasonably believed by Pacific Investment
            Management Company or the Transfer Agent to be genuine. Neither
            the Trust nor the Transfer Agent may be liable for any loss, cost
            or expense for acting on

            instructions (whether in writing or by telephone) believed by the
            party receiving such instructions to be genuine and in accordance
            with the procedures described in this Prospectus. Shareholders
            should realize that by electing the telephone, wire or e-mail
            redemption option, they may be giving up a measure of security
            that they might have if they were to redeem their shares in
            writing. Furthermore, interruptions in service may mean that a
            shareholder will be unable to effect a redemption by telephone or
            e-mail when desired. The Transfer Agent also provides written
            confirmation of transactions initiated by telephone as a procedure
            designed to confirm that telephone instructions are genuine
            (written confirmation is also provided for redemption requests
            received in writing or via e-mail). All telephone transactions are
            recorded, and Pacific Investment Management Company or the
            Transfer Agent may request certain information in order to verify
            that the person giving instructions is authorized to do so. The
            Trust or Transfer Agent may be liable for any losses due to
            unauthorized or fraudulent telephone transactions if it fails to
            employ reasonable procedures to confirm that instructions
            communicated by telephone are genuine. All redemptions, whether
            initiated by letter or telephone, will be processed in a timely
            manner, and proceeds will be forwarded by wire in accordance with
            the redemption policies of the Trust detailed below. See "Other
            Redemption Information."

             Shareholders may decline telephone exchange or redemption
            privileges after an account is opened by instructing the Transfer
            Agent in writing at least seven business days prior to the date
            the instruction is to be effective. Shareholders may experience
            delays in exercising telephone redemption privileges during
            periods of abnormal market activity. During periods of volatile
            economic or market conditions, shareholders may wish to consider
            transmitting redemption orders by telegram, facsimile or overnight
            courier.

             Defined contribution plan participants may request redemptions by
            contacting the employee benefits office, the plan administrator or
            the organization that provides recordkeeping services for the
            plan.

              . Timing of Redemption Requests and Share Price Calculations. A
            redemption request received by the Trust or its designee prior to
            the close of regular trading on the New York Stock Exchange
            (normally 4:00 p.m., Eastern time), on a day the Trust is open for
            business, is effective on that day. A redemption request received
            after that time becomes effective on the next business day.
            Redemption requests for Portfolio shares are effected at the NAV
            per share next determined after receipt of a redemption request by
            the Trust or its designee. The request must properly identify all
            relevant information, such as account number, redemption amount
            (in dollars or shares) and the Portfolio name, and must be
            executed or initialed by the appropriate signatories.

              . Other Redemption Information. Redemption proceeds will
            ordinarily be wired to the investor's bank within three business
            days after the redemption request, but may take up to seven
            business days. Redemption proceeds will be sent by wire only to
            the bank name designated on the Client Registration Application.
            The Trust may suspend the right of redemption or postpone the
            payment date at times when the New York Stock Exchange is closed,
            or during certain other periods as permitted under the federal
            securities laws.

             For shareholder protection, a request to change information
            contained in an account registration (for example, a request to
            change the bank designated to receive wire redemption proceeds)
            must be received in writing, signed by the minimum number of
            persons designated on the Client Registration Application that are
            required to effect a redemption, and accompanied by a signature
            guarantee from any eligible guarantor institution, as determined
            in accordance with the Trust's procedures. Shareholders should
            inquire as to whether a particular institution is an eligible
            guarantor institution. A signature guarantee cannot be provided by
            a notary public. In addition, corporations, trusts, and other
            institutional organizations are required to furnish evidence of
            the authority of the persons designated on the Client Registration
            Application to effect transactions for the organization.

             Due to the relatively high cost of maintaining small accounts,
            the Trust reserves the right to redeem Institutional Class and
            Administrative Class shares in any account for their then-current
            value (which will be promptly paid to the investor) if at any
            time, due to redemption by the investor, the shares in the account
            do not have a value of at least $100,000. A shareholder will
            receive advance notice of a mandatory redemption and will be given
            at least 30 days to bring the value of its account up to at least
            $100,000. This mandatory redemption policy does not apply to
            participants in PIMCO Advisors Portfolio Strategies, a managed
            product sponsored by PIMCO Advisors.

             The Trust agrees to redeem shares of each Portfolio solely in
            cash up to the lesser of $250,000 or 1% of the Portfolio's net
            assets during any 90-day period for any one shareholder. In
            consideration of the best interests of the remaining shareholders,
            the Trust reserves the right to pay any redemption proceeds
            exceeding this amount in whole or in part by a distribution in
            kind of securities held by a Portfolio in lieu of cash. When
            shares are redeemed in kind, the redeeming shareholder may incur
            transaction costs upon the disposition of the securities received
            in the distribution.

                                                                   Prospectus 32
<PAGE>

             Redemption of Portfolio shares may be suspended when trading on
            the New York Stock Exchange is restricted or during an emergency
            which makes it impracticable for the Portfolios or the Underlying
            Funds to dispose of their securities or to determine fairly the
            value of their net assets, or duing 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.


Exchange
Privilege   An investor may exchange Institutional Class or Administrative
            Class shares of a Portfolio for shares of the same class of any
            other Portfolio or other series of the Trust that offers that
            class based on the respective NAVs of the shares involved, subject
            to any restrictions on exchanges set forth in the applicable
            Fund's or series' prospectus(es). An exchange may be made by
            following the redemption procedure described above under
            "Redemptions by Mail" or, if the investor has elected the
            telephone redemption option, by calling the Trust at 1-800-927-
            4648. An investor may also exchange shares of a Portfolio for
            shares of the same class of a series of PIMCO Funds: Pacific
            Investment Management Series, an affiliated mutual fund family
            composed primarily of fixed income portfolios managed by Pacific
            Investment Management Company. Shareholders interested in such an
            exchange may request a prospectus for these other series by
            contacting PIMCO Funds: Pacific Investment Management Series at
            the same address and telephone number as the Trust.

             An investor may exchange shares only with respect to Portfolios
            or other eligible series that are registered in the investor's
            state of residence or where an exemption from registration is
            available. In addition, an exchange is generally a taxable event
            which will generate capital gains or losses, and special rules may
            apply in computing tax basis when determining gain or loss. See
            "Tax Consequences" in this Prospectus and "Taxation" in the
            Statement of Additional Information.

             The Trust reserves the right to refuse exchange purchases if, in
            the judgment of PIMCO Advisors, the purchase would adversely
            affect a Portfolio and its shareholders. In particular, a pattern
            of exchanges characteristic of "market-timing" strategies may be
            deemed by PIMCO Advisors to be detrimental to the Trust or a
            particular Portfolio. Currently, the Trust limits the number of
            "round trip" exchanges investors may make. An investor makes a
            "round trip" exchange when the investor purchases shares of a
            particular Portfolio, subsequently exchanges those shares for
            shares of a different Portfolio or other PIMCO Fund, and then
            exchanges back into the originally purchased Portfolio. 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 Portfolio) more than six round trip exchanges
            in any twelve-month period. The Trust reserves the right to impose
            additional restrictions on exchanges at any time, although it will
            attempt to give shareholders 30 days' prior notice whenever it is
            reasonably able to do so.

            How Portfolio Shares Are Priced

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

             The assets of each Portfolio consist of shares of the Underlying
            Funds, which are valued at their respective NAVs at the time of
            valuation of the Portfolios' shares. For purposes of calculating
            the NAV of Underlying Fund shares, portfolio securities and other
            assets of the Funds 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 quotes are not
            readily available may be valued, pursuant to procedures
            established by the Board of Trustees of the Underlying Fund, with
            reference to other securities or 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 Fund's Board of Trustees or persons acting at the Board's
            direction.

             Underlying Fund 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 an
            Underlying 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

33 PIMCO Funds: Multi-Manager Series
<PAGE>

            may be affected significantly on a day that the New York Stock
            Exchange is closed. As a result, to the extent that a Portfolio
            invests in Underlying Funds that hold foreign securities, the NAV
            of the Portfolio's shares may change at times when you can not
            purchase, redeem or exchange shares.

             Portfolio and Underlying 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 Underlying 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
            Underlying Funds or their 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 Underlying Funds may value securities at fair
            value or estimate their value as determined in good faith by the
            Fund's Board of Trustees or persons acting at their direction
            pursuant to procedures approved by the Board of Trustees. Fair
            valuation may also be used by the Underlying Fund's Board of
            Trustees if extraordinary events occur after the close of the
            relevant market but prior to the NYSE Close.

            Portfolio Distributions

            Each Portfolio distributes substantially all of its net investment
            income to shareholders in the form of dividends. A shareholder
            begins earning dividends on Portfolio shares the day after the
            Trust receives the shareholder's purchase payment. Dividends paid
            by each Portfolio with respect to each class of shares are
            calculated in the same manner and at the same time, but dividends
            on Administrative Class shares are expected to be lower than
            dividends on Institutional Class shares as a result of the service
            and/or distribution fees applicable to Administrative Class
            shares. The following shows when each Portfolio intends to declare
            and distribute income dividends to shareholders of record.

            ---------------------------------------------------------------------------
</TABLE>

             In addition, each Portfolio 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.

             A Portfolio's dividend and capital gain distributions with
            respect to a particular class of shares will automatically be
            reinvested in additional shares of the same class of the Portfolio
            at NAV unless the shareholder elects to have the distributions
            paid in cash. A shareholder may elect to have distributions paid
            in cash on the Client Registration Application or by submitting a
            written request, signed by the appropriate signatories, indicating
            the account number, Portfolio name(s) and wiring instructions.
            Shareholders do not pay any sales charges or other fees on the
            receipt of shares received through the reinvestment of Portfolio
            distributions.

             For further information on distribution options, please contact
            the Trust at 1-800-927-4648.

            Tax Consequences

             . Taxes on Portfolio Distributions. A shareholder subject to U.S.
            federal income tax will be subject to tax on Portfolio
            distributions whether they are paid in cash or reinvested in
            additional shares of the Portfolios. For federal income tax
            purposes, Portfolio distributions will be taxable to the
            shareholder as either ordinary income or capital gains.

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

                                                                   Prospectus 34
<PAGE>


             Portfolio distributions are taxable to shareholders even if they
            are paid from income or gains earned by a Portfolio prior to the
            shareholder's investment and thus were included in the price paid
            for the shares. For example, a shareholder who purchases shares on
            or just before the record date of a Portfolio distribution will
            pay full price for the shares and may receive a portion of his or
            her investment back as a taxable distribution.

             The Portfolios' use of a fund of funds structure could affect the
            amount, timing and character of distributions to shareholders. See
            "Taxation--Distributions" in the Statement of Additional
            Information.

             . Taxes on Redemptions or Exchanges of Shares. Any gain resulting
            from the sale of Portfolio shares will generally be subject to
            federal income tax. When a shareholder exchanges shares of a
            Portfolio for shares of another Portfolio or series of the Trust,
            the transaction will be treated as a sale of the first Portfolio's
            shares for these purposes, and any gain on those shares will
            generally be subject to federal 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
            local income tax laws to Portfolio dividends and capital
            distributions. Please see the Statement of Additional Information
            for additional information regarding the tax aspects of investing
            in the Portfolios.

            Financial Highlights

            The financial highlights table is intended to help you understand
            the financial performance of Institutional Class and
            Administrative Class shares of each Portfolio since the class of
            shares was first offered. Certain information reflects financial
            results for a single Portfolio share. The total returns in the
            table represent the rate that an investor would have earned or
            lost on an investment in a particular class of shares of a
            Portfolio, assuming reinvestment of all dividends and
            distributions. This information has been audited by
            PricewaterhouseCoopers LLP, whose report, along with each
            Portfolio's financial statements, are included in the Trust's
            annual report to shareholders. The annual report is incorporated
            by reference in the Statement of Additional Information and is
            available free of charge upon request from the Distributor.

            Summary Information

            The Portfolios are intended for investors who prefer to have their
            asset allocation decisions made by professional money managers.
            Each Portfolio has a distinct investment objective which it seeks
            to achieve by investing within specified equity and fixed income
            targets and ranges among certain Funds in the PIMCO Funds family.
            The Portfolios invest only in Funds in the PIMCO Funds family. The
            PIMCO Funds in which the Portfolios invest are called Underlying
            Funds or Funds in this Prospectus.

              Some of the Underlying Funds invest primarily in equity
            securities and are called Underlying Stock Funds. Other Underlying
            Funds invest primarily in fixed income securities, including money
            market instruments, and are called Underlying Bond Funds. The
            Portfolios are named according to their equity/fixed income
            allocation targets. For instance, the 90/10 Portfolio will
            normally invest approximately 90% of its assets in Underlying
            Stock Funds and 10% of its assets in Underlying Bond Funds.

              The table below lists the investment objectives and compares the
            asset allocation strategies of the Portfolios. Other important
            characteristics are described in the individual Portfolio
            Summaries beginning on page 5, and are discussed in greater detail
            under "Investment Objectives and Principal Investment Strategies."
            A "Summary of Principal Risks" begins on page 14.

Risk/Return You should choose among the Portfolios based on personal
Comparison  investment objectives, investment time horizon, tolerance for risk
            and personal financial circumstances. Generally speaking,
            historical data suggests that the longer the time horizon, the
            greater the likelihood that the total return of a portfolio that
            invests primarily in equity securities will be higher than the
            total return of a portfolio that invests primarily in fixed income
            securities. However, an equity portfolio is generally subject to
            higher levels of overall risk and price volatility than a fixed
            income portfolio and is considered to be a more aggressive
            investment. Based on these assumptions, the following chart gives
            some indication of the comparative risk/return potential of the
            Portfolios according to their equity/fixed income allocation
            targets and ranges. Note that these assumptions may not be correct
            in future market conditions and the chart may not accurately
            predict the actual comparative risk/return of the Portfolios under
            all market conditions.


                  90/10 Portfolio might be suitable if you have a relatively
                  long time horizon, seek long-term capital appreciation
                  potential and have a fairly high tolerance for risk and
                  volatility.

                  60/40 Portfolio might be suitable if you have a medium-
                  range time horizon, seek a balance of long-term capital
                  appreciation potential and income and have medium tolerance
                  for risk and volatility.

                  30/70 Portfolio might be suitable if you have a shorter
                  time horizon, seek a higher level of income combined with
                  some potential for long-term capital appreciation and have
                  a lower tolerance for risk and volatility.


              It is possible to lose money on investments in the Portfolios.
            While each Portfolio provides a relatively high level of
            diversification in comparison to most mutual funds, a single
            Portfolio may not be suitable as a complete investment program.
            The fact that a Portfolio may have had good performance in the
            past (for example, during the year ended 1999) is no assurance
            that the value of the Fund's investments will not decline in the
            future or appreciate at a slower rate. An investment in a

3 PIMCO Funds: Multi-Manager Series
<PAGE>

             Summary Information (continued)

Asset        PIMCO Advisors L.P. serves as the investment adviser to the
Allocation   Portfolios. PIMCO Advisors selects the Underlying Funds in which
Strategies   the Portfolios may invest. PIMCO Advisors' Asset Allocation
             Committee determines how each Portfolio allocates and reallocates
             its assets among the Underlying Funds selected by PIMCO Advisors
             according to the Portfolio's equity/fixed income allocation
             targets and ranges. The Committee attempts to diversify each
             Portfolio's assets broadly among the major asset classes and sub-
             classes represented by the Underlying Funds.

              The major equity asset classes and sub-classes held by the
             Underlying Stock Funds include those categorized by investment
             style/category (growth, blend, value, enhanced index, sector-
             related), region (U.S. equities, international developed markets,
             international emerging markets), and market capitalization (large-
             cap, mid-cap and small-cap). The major fixed income asset classes
             and sub-classes held by the Underlying Bond Funds include those
             categorized by sector/investment specialty (government securities,
             mortgage-related securities, corporate bonds and inflation-indexed
             bonds), region (U.S. fixed income, developed foreign fixed income,
             emerging markets fixed income), credit quality (investment
             grade/money market, medium grade, high yield), and duration (long-
             term, intermediate-term and short-term).

              Please see "Underlying Funds" in this Prospectus for a
             description of the Underlying Funds as categorized by their
             investment styles and main investments.

              The Portfolios may invest in any or all of the Underlying Funds,
             but will not normally invest in every Underlying Fund at any
             particular time. Each Portfolio may invest in shares of the same
             Underlying Funds; however, the percentage of each Portfolio's
             assets so invested will vary depending on the Portfolio's
             investment objective. The Asset Allocation Committee does not
             allocate a Portfolio's assets according to a predetermined blend
             of particular Underlying Funds. Instead, the Committee meets
             regularly to determine the mix of Underlying Funds appropriate for
             each Portfolio by allocating among the asset classes and sub-
             classes held by the Underlying Funds. When making these decisions,
             the Committee considers various quantitative and qualitative data
             relating to the U.S. and foreign economies and securities markets.
             This data includes projected growth trends in the U.S. and foreign
             economies, forecasts for interest rates and the relationship
             between short- and long-term interest rates (yield curve), current
             and projected trends in inflation, relative valuation levels in
             the equity and fixed income markets and various segments within
             those markets, the outlook and projected growth of various
             industrial sectors, information relating to business cycles,
             borrowing trends and the cost of capital, political trends, data
             relating to trade balances and labor information. The Committee
             may also consider proprietary research provided by the investment
             advisers and sub-advisers of the Underlying Funds.

              The Committee then allocates each Portfolio's assets among the
             Underlying Funds selected by PIMCO Advisors to fill out the asset
             class and sub-class weightings it has identified according to the
             Portfolio's equity/fixed income targets and ranges. The Committee
             has the flexibility to reallocate each Portfolio's assets in
             varying percentages among any or all of the Underlying Funds
             selected by PIMCO Advisors based on the Committee's ongoing
             analyses of the equity and fixed income markets, although these
             tactical shifts are not expected to be large or frequent in
             nature.

"Fund of     The term "fund of funds" is used to describe mutual funds, such as
Funds"       the Portfolios, that pursue their investment objectives by
Structure    investing in other mutual funds. Your cost of investing in a
and          Portfolio will generally be higher than the cost of investing in a
Expenses     mutual fund that invests directly in individual stocks and bonds.
             By investing in a Portfolio, you will indirectly bear fees and
             expenses charged by the Underlying Funds in which the Portfolio
             invests in addition to the Portfolio's direct fees and expenses.
             In addition, the use of a fund of funds structure could affect the
             timing, amount and character of distributions to you and therefore
             may increase the amount of taxes payable by you.

               Frequency
               At least annually

            The Portfolio seeks to achieve its investment objective by
            normally investing approximately 90% (within a range of 80%-100%)
            of its assets in Underlying Stock Funds and approximately 10%
            (within a range of 0%-20%) of its assets in Underlying Bond Funds.
            The Portfolio invests all of its assets in shares of the
            Underlying Funds and does not invest directly in stocks or bonds
            of other issuers.

              Please see "Asset Allocation Strategies" on page 3 for a summary
            of how the Asset Allocation Committee allocates and reallocates
            the Portfolio's assets among particular Underlying Funds.

              The Portfolio may concentrate investments in a particular
            Underlying Fund by investing more than 25% of its assets in that
            Fund.

              Based on the Portfolio's equity/fixed income allocation
            strategy, it might be suitable for an investor with a relatively
            long time horizon who seeks long-term capital appreciation
            potential and has a fairly high tolerance for risk and volatility.

--------------------------------------------------------------------------------
Principal
Risks       Allocation Risk The Portfolio's investment performance depends
            upon how its assets are allocated and reallocated among particular
            Underlying Funds. A principal risk of investing in the Portfolio
            is that the Asset Allocation Committee's allocation techniques and
            decisions and/or PIMCO Advisors' selection of Underlying Funds
            will not produce the desired results, and therefore the Portfolio
            may not achieve its investment objective.

            Underlying Fund Risks The value of your investment in the
            Portfolio is directly related to the investment performance of the
            Underlying Funds in which it invests. Therefore, the principal
            risks of investing in the Portfolio are closely related to the
            principal risks associated with the Underlying Funds and their
            investments. Because the Portfolio's allocation among the
            Underlying Funds will vary, your investment may be subject to any
            and all of these risks at different times and to different
            degrees.

            Among the principal risks of the Underlying Funds, which could
            adversely affect the net asset value, yield and total return of
            the Portfolio, are:

              .Market Risk           .Derivatives Risk    .Interest Rate Risk
              .Issuer Risk           .Foreign Investment Risk
                                                          .Credit Risk
              .Value Securities Risk .Emerging Markets Risk
                                                          .High Yield Risk
              .Growth Securities Risk.Currency Risk       .Mortgage Risk
              .Smaller Company Risk  .Focused Investment Risk
                                                          .Management Risk
              .Liquidity Risk        .Leveraging Risk

            Please see "Summary of Principal Risks" following the Portfolio
            Summaries for a description of these and other risks associated
            with the Underlying Funds and an investment in the Portfolio.

--------------------------------------------------------------------------------
Performance Shown below is summary performance information for the Portfolio
Information in a bar chart and an Average Annual Total Returns table. The
            information provides some indication of the risks of investing in
            the Portfolio by showing changes in its performance from year to
            year and by showing how the Portfolio's average annual returns
            compare with the returns of broad-based securities market indices
            and an index of mutual funds. The bar chart and the information to
            its right show performance of the Portfolio's Class A shares, but
            the returns do not reflect the impact of sales charges (loads). If
            they did, the returns would be lower than those shown. Unlike the
            bar chart, performance for Class A, B and C shares in the Average
            Annual Total Returns table reflects the impact of sales charges.
            Past performance is no guarantee of future results.

            (1) Due to the 12b-1 distribution fee imposed on Class B and Class
                C shares, a Class B or Class C shareholders may, depending
                upon 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 National Association of
                Securities Dealers, Inc.
            (2) The Administrative Fees are subject to a reduction of 0.05% on
                average net assets attributable in the aggregate to the
                Portfolio's Class A, B and C shares in excess of $2.5 billion.
            (3) Based on estimated expenses for the current fiscal year.
                Underlying Fund Expenses for the Portfolio are estimated based
                upon a recent allocation of the Portfolio's assets among
                Underlying Funds and upon the total annual operating expenses
                of Institutional Class shares of these Underlying Funds. For a
                listing of the expenses associated with each Underlying Fund,
                please see "Management of the Portfolios--Underlying Fund
                Expenses." Total Annual Portfolio Operating Expenses and the
                Examples set forth below are based on estimates of the
                Underlying Fund Expenses the Portfolio will incur. Actual
                Underlying Fund Expenses for the Portfolio are expected to
                vary with changes in the allocation of the Portfolio's assets,
                and may be higher or lower than those shown above.


            Examples. The Examples are intended to help you compare the cost
            of investing in Class A, B or C shares of the Portfolio 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 the
            Portfolio'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 Portfolio seeks to achieve its investment objective by
            normally investing approximately 60% (within a range of 50%-70%)
            of its assets in Underlying Stock Funds and approximately 40%
            (within a range of 30%-50%) of its assets in Underlying Bond
            Funds. The Portfolio invests all of its assets in shares of the
            Underlying Funds and does not invest directly in stocks or bonds
            of other issuers.

              Please see "Asset Allocation Strategies" on page 3 for a summary
            of how the Asset Allocation Committee allocates and reallocates
            the Portfolio's assets among particular Underlying Funds.

              The Portfolio may concentrate investments in a particular
            Underlying Fund by investing more than 25% of its assets in that
            Fund.

              Based on the Portfolio's equity/fixed income allocation
            strategy, it might be suitable for an investor with a medium-range
            time horizon who seeks a balance of long-term capital appreciation
            potential and income and has a medium tolerance for risk and
            volatility.

--------------------------------------------------------------------------------
Principal
Risks       Allocation Risk The Portfolio's investment performance depends
            upon how its assets are allocated and reallocated among particular
            Underlying Funds. A principal risk of investing in the Portfolio
            is that the Asset Allocation Committee's allocation techniques and
            decisions and/or PIMCO Advisors' selection of Underlying Funds
            will not produce the desired results, and therefore the Portfolio
            may not achieve its investment objective.

            Underlying Fund Risks The value of your investment in the
            Portfolio is directly related to the investment performance of the
            Underlying Funds in which it invests. Therefore, the principal
            risks of investing in the Portfolio are closely related to the
            principal risks associated with the Underlying Funds and their
            investments. Because the Portfolio's allocation among the
            Underlying Funds will vary, your investment may be subject to any
            and all of these risks at different times and to different
            degrees.

            Among the principal risks of the Underlying Funds, which could
            adversely affect the net asset value, yield and total return of
            the Portfolio, are:

              .Market Risk           .Credit Risk         .Emerging Markets
              .Issuer Risk           .High Yield Risk     Risk
              .Value Securities Risk .Mortgage Risk       .Currency Risk
              .Growth Securities Risk.Liquidity Risk      .Focused Investment
              .Smaller Company Risk  .Derivatives Risk    Risk
              .Interest Rate Risk                         .Leveraging Risk

            Please see "Summary of Principal Risks" following the Portfolio
            Summaries for a description of these and other risks associated
            with the Underlying Funds and an investment in the Portfolio.

Performance Shown below is summary performance information for the Portfolio
Information in a bar chart and an Average Annual Total Returns table. The
            information provides some indication of the risks of investing in
            the Portfolio by showing changes in its performance from year to
            year and by showing how the Portfolio's average annual returns
            compare with the returns of broad-based securities market indices
            and an index of mutual funds. The bar chart and the information to
            its right show performance of the Portfolio's Class A shares, but
            the returns do not reflect the impact of sales charges (loads). If
            they did, the returns would be lower than those shown. Unlike the
            bar chart, performance for Class A, B and C shares in the Average
            Annual Total Returns table reflects the impact of sales charges.
            Past performance is no guarantee of future results.

            (1) Due to the 12b-1 distribution fee imposed on Class B and Class
                C shares, a Class B or Class C shareholders may, depending
                upon 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 National Association of
                Securities Dealers, Inc.
            (2) The Administrative Fees are subject to a reduction of 0.05% on
                average net assets attributable in the aggregate to the
                Portfolio's Class A, B and C shares in excess of $2.5 billion.
            (3) Based on estimated expenses for the current fiscal year.
                Underlying Fund Expenses for the Portfolio are estimated based
                upon a recent allocation of the Portfolio's assets among
                Underlying Funds and upon the total annual operating expenses
                of Institutional Class shares of these Underlying Funds. For a
                listing of the expenses associated with each Underlying Fund,
                please see "Management of the Portfolios--Underlying Fund
                Expenses." Total Annual Portfolio Operating Expenses and the
                Examples set forth below are based on estimates of the
                Underlying Fund Expenses the Portfolio will incur. Actual
                Underlying Fund Expenses for the Portfolio are expected to
                vary with changes in the allocation of the Portfolio's assets,
                and may be higher or lower than those shown above.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class A, B or C shares of the Portfolio 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 the
            Portfolio'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 Portfolio seeks to achieve its investment objective by
            normally investing approximately 30% (within a range of 25%-35%)
            of its assets in Underlying Stock Funds and approximately 70%
            (within a range of 65%-75%) of its assets in Underlying Bond
            Funds. The Portfolio invests all of its assets in shares of the
            Underlying Funds and does not invest directly in stocks or bonds
            of other issuers.

              Please see "Asset Allocation Strategies" on page 3 for a summary
            of how the Asset Allocation Committee allocates and reallocates
            the Portfolio's assets among particular Underlying Funds.

              The Portfolio may concentrate investments in a particular
            Underlying Fund by investing more than 25% of its assets in that
            Fund.

              Based on the Portfolio's equity/fixed income allocation
            strategy, it might be suitable for an investor with a shorter time
            horizon who seeks a higher level of income combined with some
            potential for long-term capital appreciation and has a lower
            tolerance for risk and volatility.

--------------------------------------------------------------------------------
Principal
Risks       Allocation Risk The Portfolio's investment performance depends
            upon how its assets are allocated and reallocated among particular
            Underlying Funds. A principal risk of investing in the Portfolio
            is that the Asset Allocation Committee's allocation techniques and
            decisions and/or PIMCO Advisors' selection of Underlying Funds
            will not produce the desired results, and therefore the Portfolio
            may not achieve its investment objective.

            Underlying Fund Risks The value of your investment in the
            Portfolio is directly related to the investment performance of the
            Underlying Funds in which it invests. Therefore, the principal
            risks of investing in the Portfolio are closely related to the
            principal risks associated with the Underlying Funds and their
            investments. Because the Portfolio's allocation among the
            Underlying Funds will vary, your investment may be subject to any
            and all of these risks at different times and to different
            degrees.

            Among the principal risks of the Underlying Funds, which could
            adversely affect the net asset value, yield and total return of
            the Portfolio, are:

              .Interest Rate Risk .Value Securities Risk   .Emerging Markets
              .Credit Risk        .Growth Securities Risk   Risk
              .High Yield Risk    .Smaller Company Risk    .Currency Risk
              .Mortgage Risk      .Liquidity Risk          .Focused Investment
              .Market Risk        .Derivatives Risk         Risk
              .Issuer Risk        .Foreign Investment Risk .Leveraging Risk
                                                           .Management Risk

            Please see "Summary of Principal Risks" following the Portfolio
            Summaries for a description of these and other risks associated
            with the Underlying Funds and an investment in the Portfolio.

Performance Shown below is summary performance information for the Portfolio
Information in a bar chart and an Average Annual Total Returns table. The
            information provides some indication of the risks of investing in
            the Portfolio by showing changes in its performance from year to
            year and by showing how the Portfolio's average annual returns
            compare with the returns of broad-based securities market indices
            and an index of mutual funds. The bar chart and the information to
            its right show performance of the Portfolio's Class A shares, but
            the returns do not reflect the impact of sales charges (loads). If
            they did, the returns would be lower than those shown. Unlike the
            bar chart, performance for Class A, B and C shares in the Average
            Annual Total Returns table reflects the impact of sales charges.
            Past performance is no guarantee of future results.

                 billion.
            (3)  Based on estimated expenses for the current fiscal year.
                 Underlying Fund Expenses for the Portfolio are estimated
                 based upon a recent allocation of the Portfolio's assets
                 among Underlying Funds and upon the total annual operating
                 expenses of Institutional Class shares of these Underlying
                 Funds. For a listing of the expenses associated with each
                 Underlying Fund, please see "Management of the Portfolios--
                 Underlying Fund Expenses." Total Annual Portfolio Operating
                 Expenses and the Examples set forth below are based on
                 estimates of the Underlying Fund Expenses the Portfolio will
                 incur. Actual Underlying Fund Expenses for the Portfolio are
                 expected to vary with changes in the allocation of the
                 Portfolio's assets, and may be higher or lower than those
                 shown above.


            Examples. The Examples are intended to help you compare the cost
            of investing in Class A, B or C shares of the Portfolio 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 the
            Portfolio'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 Portfolio changes with the
            values of that Portfolio's investments in the Underlying Funds.
            Many factors can affect those values. The factors that are most
            likely to have a material effect on a particular Portfolio's
            investments as a whole are called "principal risks." The principal
            risks of each Portfolio are identified in the Portfolio Summaries
            beginning on page 5 and are summarized in this section. There is
            no guarantee that a Portfolio will be able to achieve its
            investment objective.

            Allocation Risk

            Each Portfolio's investment performance depends upon how its
            assets are allocated and reallocated among particular Underlying
            Funds according to the Portfolio's equity/fixed income allocation
            targets and ranges. A principal risk of investing in each
            Portfolio is that PIMCO Advisors' Asset Allocation Committee will
            make less than optimal or poor asset allocation decisions and/or
            that PIMCO Advisors will make less than optimal decisions in
            selecting the Underlying Funds in which the Portfolios invest. The
            Committee attempts to identify asset classes and sub-classes
            represented by the Underlying Funds that will provide consistent,
            quality performance for the Portfolios, but there is no guarantee
            that the Committee's allocation techniques will produce the
            desired results. It is possible that the Committee and/or PIMCO
            Advisors will focus on Underlying Funds that perform poorly or
            underperform other available Funds under various market
            conditions. You could lose money on your investment in a Portfolio
            as a result of these allocation decisions.

            Underlying Fund Risks

            Because each Portfolio invests all of its assets in Underlying
            Funds, the risks associated with investing in the Portfolios are
            closely related to the risks associated with the securities and
            other investments held by the Underlying Funds. The ability of a
            Portfolio to achieve its investment objective will depend upon the
            ability of the Underlying Funds to achieve their objectives. There
            can be no assurance that the investment objective of any
            Underlying Fund will be achieved.

              Each Portfolio's net asset value will fluctuate in response to
            changes in the net asset values of the Underlying Funds in which
            it invests. The extent to which the investment performance and
            risks associated with a particular Portfolio correlate to those of
            a particular Underlying Fund will depend upon the extent to which
            the Portfolio's assets are allocated from time to time for
            investment in the Underlying Fund, which will vary. A Portfolio's
            investment in a particular Underlying Fund may and in some cases
            is expected to exceed 25% of its assets. To the extent that a
            Portfolio invests a significant portion of its assets in an
            Underlying Fund, it will be particularly sensitive to the risks
            associated with that Fund.

              The following summarizes principal risks associated with
            investments in the Underlying Funds and, indirectly, with your
            investment in a Portfolio. Each Underlying Fund may be subject to
            additional principal risks other than those described below
            because the types of investments made by an Underlying Fund can
            change over time. The summary is not intended to be exhaustive.
            For a more complete description of these risks and the securities
            and investment techniques used by the Underlying Funds, please
            refer to the Statement of Additional Information and the
            Underlying Fund prospectuses, which are incorporated herein by
            reference and are available free of charge by telephoning the
            Distributor at 1-800-426-0107.

Market      The market price of securities owned by an Underlying Fund may go
Risk        up or down, 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 and the Underlying Stock
            Funds are particularly sensitive to these market risks.

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

                                                                   Prospectus 14
<PAGE>

Value
Securities  Each Underlying Stock Fund may invest in companies that may not be
Risk        expected to experience significant earnings growth, but whose
            securities the Fund's portfolio manager believes are selling at a
            price lower than their true value. PIMCO Equity Income,
            Renaissance, Value, Small-Cap Value, Capital Appreciation, Mid-Cap
            and Micro-Cap Funds and PIMCO Allianz Select International Fund
            place particular emphasis on value securities. Companies that
            issue value securities may have experienced adverse business
            developments or may be subject to special risks that have caused
            their securities to be out of favor. If a portfolio manager's
            assessment of a company's prospects is wrong, or if the market
            does not recognize the value of the company, the price of its
            securities may decline or may not approach the value that the
            portfolio manager anticipates.

Growth
Securities  Each Underlying Stock Fund may invest in equity securities of
Risk        companies that its portfolio manager believes will experience
            relatively rapid earnings growth. PIMCO Growth, Target,
            Opportunity, Capital Appreciation, Mid-Cap, Micro-Cap and
            Innovation Funds and PIMCO Allianz Select International Fund place
            particular emphasis on growth securities. Growth securities
            typically trade at higher multiples of current earnings than other
            securities. Therefore, the values of growth securities may be more
            sensitive to changes in current or expected earnings than the
            values of other securities.

Smaller
Company     The general risks associated with equity securities and liquidity
Risk        risk are particularly pronounced for securities of companies with
            market capitalizations that are small compared to other publicly
            traded companies. These companies may have limited product lines,
            markets or financial resources or they may depend on a few key
            employees. Securities of smaller companies may trade less
            frequently and in lesser volume than more widely held securities
            and their values may fluctuate more sharply than other securities.
            They may also trade in the over-the-counter market or on a
            regional exchange, or may otherwise have limited liquidity. PIMCO
            Opportunity, Micro-Cap, Small-Cap Value and Innovation Funds
            generally have substantial exposure to this risk. PIMCO Target and
            Mid-Cap Funds and PIMCO Allianz Select International Fund also
            have significant exposure to this risk because they invest
            substantial assets in companies with medium-sized market
            capitalizations, which are smaller and generally less-seasoned
            than the largest companies. Smaller company risk also applies to
            fixed income securities issued by smaller companies and may affect
            certain investments of the Underlying Bond Funds.

Liquidity   Many of the Underlying Funds are subject to liquidity risk.
Risk        Liquidity risk exists when particular investments are difficult to
            purchase or sell, possibly preventing a Fund from selling out of
            these illiquid securities at an advantageous time or price.
            Underlying Funds with principal investment strategies that involve
            securities of companies with smaller market capitalizations,
            foreign securities, derivatives or securities with substantial
            market and/or credit risk tend to have the greatest exposure to
            liquidity risk.

Derivatives
Risk        Many of the Underlying Funds may, but are not required to, use a
            number of derivative instruments for risk management purposes or
            as part of their 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. An
            Underlying 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. Also, an Underlying Fund's 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 the various derivative instruments in which the
            Underlying Funds may invest and the risks associated with each
            instrument is included in the Underlying Fund prospectuses and 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 Underlying 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.

              Leveraging 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 an Underlying 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 leveraging risk, the Underlying Funds
            observe asset segregation requirements to cover their 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 an
            Underlying 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 considerations.

              Market and Other Risks Like most other investments, derivative
            instruments are subject to the general risk that the market value
            of the instrument will change in a way detrimental to an
            Underlying 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 an Underlying
            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 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 investments of an
            Underlying Fund. An Underlying 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 an Underlying 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, an Underlying Fund's use
            of derivatives may also cause the Fund to realize higher amounts
            of short-term capital gains (taxed at ordinary income tax rates
            when distributed to shareholders who are individuals) than if the
            Fund had not used such instruments.

Foreign     Many Underlying Funds (in particular, PIMCO International,
(non-       Structured Emerging Markets, Tax-Efficient Structured Emerging
U.S.)       Markets, Global Bond, Foreign Bond and Emerging Markets Bond Funds
Investment  and PIMCO Allianz Select International Fund) invest in securities
Risk        of foreign issuers, securities traded principally in securities
            markets outside the United States and/or securities denominated in
            foreign currencies (together, "foreign securities"). These Funds
            may experience more rapid and extreme changes in value than Funds
            that invest exclusively in securities of U.S. issuers or
            securities that trade exclusively in U.S. markets.

              The securities markets of many foreign countries are relatively
            small, with a limited number of companies representing a small
            number of industries. Foreign securities often trade with less
            frequency and volume than domestic securities and therefore may
            exhibit greater price volatility. 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 an Underlying 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. To
            the extent that an Underlying Fund invests a significant portion
            of its assets in a narrowly defined geographic area such as
            Eastern Europe, South Africa or Asia, the Fund will generally have
            more exposure to regional economic risks associated with foreign
            investments. Adverse conditions in certain regions (such as
            Southeast Asia) can also adversely affect securities of other
            countries whose economies appear to be unrelated. In addition,
            special U.S. tax considerations may apply to an Underlying Fund's
            investment in foreign securities.


                                                                   Prospectus 16
<PAGE>

              Certain Underlying Bond Funds 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    Certain Underlying Funds (in particular, PIMCO Structured Emerging
Markets     Markets, Tax-Efficient Structured Emerging Markets and Emerging
Risk        Markets Bond Funds) may invest in the securities of issuers based
            in countries with developing or "emerging market" 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
Risk        Many Underlying Funds may invest directly in foreign currencies or
            in securities that trade in, or receive revenues in, foreign
            currencies. To the extent that they do so, these Funds 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. PIMCO Global Bond, Foreign Bond, Emerging Markets Bond,
            International, Structured Emerging Markets and Tax-Efficient
            Structured Emerging Markets Funds and PIMCO Allianz Select
            International Fund are particularly sensitive to currency risk.
            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. For example, uncertainty
            surrounds the introduction of the euro (a common currency unit for
            the European Union) and its effect on the value of European
            currencies as well as securities denominated in local European
            currencies. These and other currencies in which Underlying Fund
            assets are denominated may be devalued against the U.S. dollar,
            resulting in a loss to such Funds.

Focused
Investment  Focusing Fund investments in a small number of issuers, industries
Risk        or foreign currencies increases risk. PIMCO Global Bond, Foreign
            Bond and Emerging Markets Bond Funds are "non-diversified," which
            means that they invest in a smaller number of issuers than
            diversified mutual funds. Other Underlying Funds also normally
            invest in a relatively small number of issuers. In addition, many
            Underlying Bond Funds may invest a substantial portion of their
            assets in the bonds of similar projects or from issuers in the
            same state. To the extent that they focus their investments, the
            Underlying Funds may have more risk because changes in the value
            of a single security or the impact of a single economic, political
            or regulatory occurrence may have a greater adverse impact on the
            Underlying Fund's net asset value. Some of those investments also
            may present substantial credit or other risks. PIMCO
            International, Structured Emerging Markets, Tax-Efficient
            Structured Emerging Markets, Global Bond, Foreign Bond and
            Emerging Markets Bond Funds and PIMCO Allianz Select International
            Fund may be subject to increased risk to the extent they focus
            their assets in securities denominated in a particular foreign
            currency or in a narrowly defined geographic area outside the
            U.S., because companies in these areas may share common
            characteristics and are often subject to similar business risks
            and regulatory burdens, and their securities may react similarly
            to economic, market, political or other developments. Similarly,
            PIMCO Innovation Fund is vulnerable to events affecting companies
            which use innovative technologies to gain a strategic, competitive
            advantage in their industry and companies that provide and service
            those technologies because it normally concentrates its
            investments in those companies. Also, the Underlying Funds may
            from time to time have greater risk to the extent they invest a
            substantial portion of their assets in companies in related
            industries such as "technology" or "financial and business
            services," which may share common characteristics, are often
            subject to similar business risks and regulatory burdens, and
            whose securities may react similarly to economic, market,
            political or other developments.

             Although each Portfolio normally invests in a number of different
            Underlying Funds, to the extent that a Portfolio concentrates a
            significant portion of its assets in a single Underlying Fund, it
            will be particularly sensitive to the risks associated with that
            Fund and any investments in which that Fund concentrates.

Leveraging
Risk        Leverage, including borrowing, will cause the value of an
            Underlying  Fund's shares to be more volatile that if the Fund did
            not use leverage. This is because leverage tends to exaggerate the
            effect of any increase or decrease in the value of a Fund's
            portfolio securities. Certain Underlying Funds may engage in
            transactions or purchase instruments that give rise to forms of
            leverage. Such transactions and instruments may include, among
            others, the use of reverse repurchase agreements and other
            borrowings,

            the investment of collateral from loans of portfolio securities,
            or the use of when-issued, delayed-delivery or forward commitment
            transactions. An Underlying Fund's use of derivatives may also
            involve leverage. The use of leverage may also cause an Underlying
            Fund to liquidate portfolio positions when it may not be
            advantageous to do so in order to satisfy its obligations or to
            meet segregation requirements.

Interest    All of the Underlying Funds that invest in fixed income
Rate Risk   securities, and particularly the Underlying Bond Funds, are
            subject to interest rate risk. Changes in the market values of
            fixed income securities are largely a function of changes in the
            current level of interest rates. The value of an Underlying Fund's
            investments in fixed income securities will typically change as
            the level of interest rates fluctuate. During periods of declining
            interest rates, the value of fixed income securities generally
            rise. Conversely, during periods of rising interest rates, the
            value of fixed income securities generally decline.

             "Duration" is one 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. Securities with longer
            durations tend to be more sensitive to changes in interest rates,
            usually making them more volatile than securities with shorter
            durations. Accordingly, Underlying Bond Funds with longer average
            portfolio durations (e.g., PIMCO Long-Term U.S. Government Fund)
            will generally be more sensitive to changes in interest rates than
            Funds with shorter average portfolio durations (e.g., PIMCO Money
            Market, Short-Term and Low Duration Funds). Also, some portfolios
            (e.g., those with mortgage-backed and other prepayable securities)
            have changing durations and may have increasing durations
            precisely when that is least advantageous (i.e., when interest
            rates are rising).

             Many Underlying Funds, including most of the Underlying Bond
            Funds, may invest in securities that are particularly sensitive to
            fluctuations in prevailing interest rates and have relatively high
            levels of interest rate risk. These include various mortgage-
            related securities (for instance, the interest-only or "IO" class
            of a stripped mortgage-backed security) and "zero coupon"
            securities (fixed income securities, including certain U.S.
            Government securities, that do not make periodic interest payments
            and are purchased at a discount from their value at maturity).

Credit      All of the Underlying Funds are subject to credit risk. This is
Risk        the risk that the issuer or the guarantor of a fixed income
            security, or the counterparty to a derivatives contract,
            repurchase agreement or a loan of portfolio securities, will be
            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
            reflecting in credit ratings provided by rating agencies such as
            Moody's Investors Service, Inc. ("Moody's") and Standard & Poor's
            Ratings Services ("S&P").

             The Underlying Funds that invest in fixed income securities
            (particularly the Underlying Bond Funds) are subject to varying
            degrees of risk that the issuers of the securities will have their
            credit ratings downgraded or will default, potentially reducing
            the Underlying Fund's share price and income level. Nearly all
            fixed income securities are subject to some credit risk, whether
            the issuers of the securities are corporations, states and local
            governments or foreign governments. Even certain U.S. Government
            securities are subject to credit risk.


High        High yield securities (commonly known as "junk bonds") are fixed
Yield       income securities rated lower than Baa by Moody's or BBB by S&P,
Risk        or unrated securities determined to be of comparable quality.
            Underlying Bond Funds which invest in high yield securities (in
            particular, PIMCO High Yield and Emerging Markets Bond Funds) may
            be subject to greater levels of interest rate, credit and
            liquidity risk than Funds that invest exclusively in higher
            quality fixed income securities (e.g., PIMCO Money Market and
            Long-Term U.S. Government Funds). These securities are considered
            predominately speculative with respect to the issuer's continuing
            ability to make principal and interest payments (credit risk).
            These securities may also be more susceptible to real or perceived
            adverse economic and competitive industry conditions than higher
            quality fixed income securities. An economic downturn or period of
            rising interest rates could adversely affect the market for these
            securities and reduce an Underlying Bond Fund's ability to sell
            them (liquidity risk).

Mortgage    Most of the Underlying Bond Funds may invest in mortgage-related
Risk        securities. 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, an Underlying Fund that holds mortgage-related securities
            may exhibit additional volatility. This is sometimes referred to
            as extension risk. In addition, mortgage-related securities may
            involve special risks relating to unanticipated rates of
            prepayment on the mortgages underlying the securities. This is
            sometimes referred to as prepayment

                                                                   Prospectus 18
<PAGE>

            risk. Declining interest rates may tend to increase prepayments,
            and these prepayments would have to be reinvested at the then-
            prevailing lower interest rates. Therefore, an Underlying Fund
            that holds mortgage-related securities may have less potential for
            capital appreciation during periods of declining interest rates
            than Funds that invest in other types of fixed income securities
            of similar maturities.


Management  Each Underlying Fund is subject to management risk because it is
Risk        an actively managed investment portfolio. PIMCO Advisors, Pacific
            Investment Management Company LLC ("Pacific Investment Management
            Company"), and the sub-advisers and individual portfolio managers
            of the Underlying Funds will apply investment techniques and risk
            analyses in making investment decisions for the Funds, but there
            can be no guarantee that they will produce the desired results.

A Note on   Each Portfolio may invest in PIMCO StocksPLUS Fund. While the
PIMCO       investment objective of that Fund is to achieve a total return
StocksPLUS  which exceeds the total return performance of the S&P 500 Index,
Fund        it does so by investing substantially all of its assets in a
            combination of equity-based (S&P 500 Index) derivative
            instruments, backed by a portfolio of fixed income securities.
            Consequently, the risks of investing in the Fund include
            derivatives risk and the risks generally associated with the
            Underlying Bond Funds. To the extent that the Fund invests in S&P
            500 Index derivatives backed by a portfolio of fixed income
            securities, under certain conditions, generally in a market where
            the value of both S&P 500 Index derivatives and fixed income
            securities are declining, the Fund may experience greater losses
            than would be the case if it were to invest directly in a
            portfolio of S&P 500 Index stocks.

            Investment Objectives and Principal Investment Strategies

            The investment objective and principal investment strategies of
            each Portfolio are described below. There can be no assurance that
            the investment objective of any Portfolio will be achieved.
            Because the market value of each Portfolio's investments will
            change, the net asset value per share of each Portfolio will also
            vary.

             The Portfolios are intended for investors who prefer to have
            their asset allocation decisions made by professional money
            managers. Each Portfolio seeks to achieve its investment objective
            by investing within specified equity and fixed income ranges among
            the Underlying Funds. Each Underlying Fund is a series of the
            Trust or PIMCO Funds: Pacific Investment Management Series and is
            managed by PIMCO Advisors and/or its affiliates.

Portfolio   90/10 Portfolio seeks long-term capital appreciation. Under normal
Descriptionsconditions, approximately 90% of the Portfolio's assets will be
            allocated among Underlying Stock Funds and 10% among Underlying
            Bond Funds.

            60/40 Portfolio seeks long-term capital appreciation and current
            income. Under normal conditions, approximately 60% of the
            Portfolio's assets will be allocated among Underlying Stock Funds
            and 40% among Underlying Bond Funds.

            30/70 Portfolio seeks current income. Long-term capital
            appreciation is a secondary objective. Under normal conditions,
            approximately 30% of the Portfolio's assets will be allocated
            among Underlying Stock Funds and 70% among Underlying Bond Funds.

             PIMCO Advisors serves as the investment adviser to the Portfolios
            and selects the Underlying Funds in which the Portfolios may
            invest. PIMCO Advisors' Asset Allocation Committee determines how
            each Portfolio allocates and reallocates its assets among the
            Underlying Funds selected by PIMCO Advisors according to the
            Portfolio's equity/fixed income allocation targets and ranges.
            Please see "Asset Allocation Strategies" in the Summary
            Information section above for a description of the allocation
            strategies and techniques used by the Committee. The table below
            illustrates the equity and fixed income allocation targets and
            typical ranges for each Portfolio under normal market conditions.

              Each Portfolio invests all of its assets in Underlying Funds and
            may invest in any or all of the Funds. However, it is expected
            that a Portfolio will invest in only some of the Underlying Funds
            at any particular time. A Portfolio's investment in a particular
            Underlying Fund may exceed 25% of the Portfolio's total assets. To
            the extent that a Portfolio invests a significant portion of its
            assets in an Underlying Fund, it will be particularly sensitive to
            the risks associated with that Fund. The particular Underlying
            Funds in which each Portfolio may invest, the equity and fixed
            income allocation targets and ranges specified above, and the
            percentage of each Portfolio's assets invested from time to time
            in any Underlying Fund or combination of Funds may be changed from
            time to time without the approval of the Portfolio's shareholders.
            Each Portfolio is also subject to certain investment restrictions
            that are described under "Investment Restrictions" in the
            Statement of Additional Information.

Equity      The equity portion of each Portfolio will be allocated among a

of the      equity-based asset classes and sub-classes and a variety of
Portfolios  investment objectives and strategies. By allocating assets among
            these Funds, the equity portions of the Portfolios can be
            diversified in multiple ways, including the following:

            investment objectives and strategies, please see "Underlying
            Funds."

Temporary   In response to unfavorable market and other conditions, each
Defensive   Portfolio may invest up to 100% of its assets in PIMCO Money
Strategies  Market Fund (and may deviate from its asset allocation range) for
            temporary defensive purposes. A Portfolio may also borrow money
            for temporary or emergency purposes. These temporary strategies
            would be inconsistent with the Portfolio's investment objective
            and principal investment strategies and may adversely affect the
            Portfolio's ability to achieve its investment objective.


Portfolio   A change in the securities held by a Portfolio is known as
Turnover    "portfolio turnover." Because PIMCO Advisors does not expect to
            reallocate the Portfolios' assets among the Underlying Funds on a
            frequent basis, the portfolio turnover rates for the Portfolios
            are expected to be modest (i.e., less than 25%) in comparison to
            most mutual funds. However, the Portfolios' indirectly bear the
            expenses associated with portfolio turnover of the Underlying
            Funds, a number of which have fairly high portfolio turnover rates
            (i.e., in excess of 100%). High portfolio turnover involves
            correspondingly greater expenses to an Underlying Fund, including
            brokerage commissions or dealer mark-ups and other transaction
            costs on the sale of securities and reinvestments in other
            securities. Shareholders in the Portfolios may also bear expenses
            directly or indirectly through sales of securities held by the
            Portfolios and the Underlying Funds which result in realization of
            taxable capital gains. To the extent such gains relate to
            securities held for twelve months or less, such gains will be
            short-term capital gains taxed at ordinary income tax rates when
            distributed to shareholders who are individuals. The trading costs
            and tax effects associated with portfolio turnover may adversely
            affect a Portfolio's performance and the return to shareholders.


Changes     The investment objective, equity/fixed income allocation targets
in          and ranges, and, unless otherwise noted, other investment policies
Investment  of each Portfolio described in this Prospectus may be changed by
Objectives  the Board of Trustees without shareholder approval. If there is a
and         change in a Portfolio's investment objective, allocation target or
Policies    range, or other investment policies, shareholders should consider

Underlying  The investment objective of each Underlying Bond Fund (except as
Bond        provided below) is to seek to realize maximum total return,
Funds       consistent with preservation of capital and prudent investment
            management. The "total return" sought by most of the Underlying
            Bond Funds will consist 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. The investment
            objective of PIMCO Real Return Bond Fund is to seek to realize
            maximum real return, consistent with preservation of real capital
            and prudent investment management. "Real return" is a measure of
            the change in purchasing power of money invested in a particular
            investment after adjusting for inflation. The investment objective
            of each of PIMCO Money Market Fund and PIMCO Short-Term Fund is to
            seek to obtain maximum current income, consistent with
            preservation of capital and daily liquidity. PIMCO Money Market
            Fund also attempts to maintain a stable net asset value of $1.00
            per share, although there can be no assurance that it will be
            successful in doing so.

             The following provides a concise description of the main
            investments of and other information relating to each Underlying
            Bond Fund. For a complete description of these Funds, please see

            These and the other types of securities and investment techniques

            Underlying Funds. For further information concerning the

Additional  In addition to the Funds listed above, a Portfolio may invest in

            Advisors and without shareholder approval.

            Other Risk Information

Potential   PIMCO Advisors has broad discretion to allocate and reallocate the
Conflicts   Portfolios' assets among the Underlying Funds consistent with the
of          Portfolios' investment objectives and policies and asset
Interest    allocation targets and ranges. Although PIMCO Advisors does not
            charge an investment advisory fee for its asset allocation
            services, PIMCO Advisors and its affiliates indirectly receive
            fees (including investment advisory and administrative fees) from
            the Underlying Funds in which the Portfolios invest. In this
            regard, PIMCO Advisors has a financial incentive to invest a
            Portfolio's assets in Underlying Funds with higher fees than other
            Funds, even if it believes that alternate investments would better
            serve the Portfolio's investment program. PIMCO Advisors is
            legally obligated to disregard that incentive in making asset
            allocation decisions for the Portfolios. The Trustees and officers
            of the Trust may also have conflicting interests in fulfilling
            their fiduciary duties to both the Portfolios and the Underlying
            Funds of the Trust.

            management.

              PIMCO Advisors has retained its affiliate, Pacific Investment
            Management Company, to provide various administrative and other
            services required by the Portfolios in its capacity as sub-
            administrator. PIMCO Advisors and the sub-administrator may retain
            other affiliates to provide certain of these services.

Asset       PIMCO Advisors selects the Underlying Funds in which the
Allocation  Portfolios may invest. PIMCO Advisors' Asset Allocation Committee
Committee   is responsible for determining how the Portfolios' assets are
            allocated and reallocated from time-to-time among the Underlying
            Funds selected by PIMCO Advisors. The following provides
            information about the individuals who comprise the Asset
            Allocation Committee and are primarily responsible for making
            asset allocation and other investment decisions for the
            Portfolios.

Advisory    The Portfolios do not pay any fees to PIMCO Advisors under the
Fees        Trust's investment advisory agreement in return for the advisory
            and asset allocation services provided by PIMCO Advisors. The
            Portfolios do, however, indirectly pay their proportionate share
            of the advisory fees paid to PIMCO Advisors and Pacific Investment
            Management Company by the Underlying Funds in which the Portfolios
            invest. See "Underlying Fund Expenses" below.

Administrative
Fees

            Each Portfolio pays for the administrative services it requires
            under a fee structure which is essentially fixed. Class A, Class B
            and Class C shareholders of each Portfolio pay an administrative
            fee to PIMCO Advisors, computed as a percentage of the Portfolio's
            assets attributable in the aggregate to those classes of shares.
            PIMCO Advisors, in turn, provides or procures administrative
            services for Class A, Class B and Class C shareholders and also
            bears the costs of most third-party services required by the
            Portfolios, including audit, custodial, portfolio accounting,
            legal, transfer agency and printing costs. The Portfolios do bear
            other expenses which are not covered under the administrative fee
            which may vary and affect the total level of expenses paid by
            Class A, Class B and Class C shareholders, such as brokerage fees,
            commissions and other transaction expenses, costs of borrowing
            money, including interest expenses, and fees and expenses of the
            Trust's disinterested Trustees.

              Each Portfolio pays monthly administrative fees to PIMCO
            Advisors at an annual rate of 0.40% based on the average daily net
            assets attributable in the aggregate to the Portfolio's Class A,
            Class B

<PAGE>


            and Class C shares up to $2.5 billion, and 0.35% based on such
            average daily net assets in excess of $2.5 billion. The Portfolios
            also indirectly pay their proportionate share of the
            administrative fees charged by PIMCO Advisors and Pacific
            Investment Management Company to the Underlying Funds in which the
            Portfolios invest. See "Underlying Fund Expenses" below.

Underlying  The expenses associated with investing in a "fund of funds," such
Fund        as the Portfolios, are generally higher than those for mutual
Expenses    funds that do not invest primarily in other mutual funds. This is
            because shareholders in a "fund of funds" indirectly pay a portion
            of the fees and expenses charged at the underlying fund level.

              The Portfolios are structured in the following ways to lessen
            the impact of expenses incurred at the Underlying Fund level:

            . The Portfolios do not pay any fees for asset allocation or
              advisory services under the Trust's investment advisory
              agreement.

            . The Underlying Funds invest in Institutional Class shares of the
              Underlying Funds, which are not subject to any sales charges or
              12b-1 fees.

              The following table summarizes the annual expenses borne by
            Institutional Class shareholders of the Underlying Funds (based on
            estimates for the current fiscal year). Because the Portfolios
            invest in Institutional Class shares of the Underlying Funds,
            shareholders of each Portfolio indirectly bear a proportionate
            share of these expenses, depending upon how the Portfolio's assets
            are allocated from time to time among the Underlying Funds. See
            "Fees and Expenses of the Portfolio" in each Portfolio Summary
            above.

Distributor The Trust's Distributor is PIMCO Funds Distributors LLC, a wholly
            owned subsidiary of PIMCO Advisors. The Distributor, located at
            2187 Atlantic Street, Stamford, CT 06902, is a broker-dealer
            registered with the Securities and Exchange Commission.

            Investment Options -- Class A, B and C Shares

            The Trust offers investors Class A, Class B and Class C shares of
            each Portfolio in this Prospectus. Each class of shares is subject
            to different types and levels of sales charges than the other
            classes and bears a different level of expenses.

             The class of shares that is best for you depends upon a number of
            factors, including the amount and the intended length of your
            investment. The following summarizes key information about each
            class to help you make your investment decision, including the
            various expenses associated with each class. More extensive
            information about the Trust's multi-class arrangements is included
            in the PIMCO Funds Shareholders' Guide for Class A, B and C Shares
            (the "Guide"), which is included as part of the Statement of
            Additional Information and can be obtained free of charge from the
            Distributor. See "How to Buy and Sell Shares--PIMCO Funds
            Shareholders' Guide" below.

Class A     .   You pay an initial sales charge of up to 5.50% when you buy
Shares          Class A shares. The sales charge is deducted from your
                investment so that not all of your purchase payment is
                invested.

            .   You may be eligible for a reduction or a complete waiver of
                the initial sales charge under a number of circumstances. For
                example, you normally pay no sales charge if you purchase
                $1,000,000 or more of Class A shares. Please see the Guide for
                details.

            .   Class A shares are subject to lower 12b-1 fees than Class B or
                Class C shares. Therefore, Class A shareholders generally pay
                lower annual expenses and receive higher dividends than Class
                B or Class C shareholders.

            .   You normally pay no contingent deferred sales charge ("CDSC")
                when you redeem Class A shares, although you may pay a 1% CDSC
                if you purchase $1,000,000 or more of Class A shares (and
                therefore pay no initial sales charge) and then redeem the
                shares during the first 18 months after your initial purchase.
                The Class A CDSC is waived for certain categories of investors
                and does not apply if you are otherwise eligible to purchase
                Class A shares without a sales charge. Please see the Guide
                for details.

Class B     .   You do not pay an initial sales charge when you buy Class B
Shares          shares. The full amount of your purchase payment is invested
                initially.

            .  You normally pay a CDSC of up to 5% if you redeem Class B
               shares during the first six years after your initial purchase.
               The amount of the CDSC declines the longer you hold your Class
               B shares. You pay no CDSC if you redeem during the seventh year
               and thereafter. The Class B CDSC is waived for certain
               categories of investors. Please see the Guide for details.

            .  Class B shares are subject to higher 12b-1 fees than Class A
               shares for the first seven years they are held. During this
               time, Class B shareholders normally pay higher annual expenses
               and receive lower dividends than Class A shareholders.

            .  Class B shares automatically convert into Class A shares after
               they have been held for seven years. After the conversion takes
               place, the shares are subject to the lower 12b-1 fees paid by
               Class A shares.

Class C     .  You do not pay an initial sales charge when you buy Class C
Shares         shares. The full amount of your purchase payment is invested
               initially.

            .  You normally pay a CDSC of 1% if you redeem Class C shares
               during the first year after your initial purchase. The Class C
               CDSC is waived for certain categories of investors. Please see
               the Guide for details.

            .  Class C shares are subject to higher 12b-1 fees than Class A
               shares. Therefore, Class C shareholders normally pay higher
               annual expenses and receive lower dividends than Class A
               shareholders.

            .  Class C shares do not convert into any other class of shares.
               Because Class B shares convert into Class A shares after seven
               years, Class C shares will normally be subject to higher
               expenses and will pay lower dividends than Class B shares if
               the shares are held for more than seven years.

Class A     The initial sales charge varies depending upon the size of your
Shares      purchase, as set forth below. No sales charge is imposed where
            Class A shares are issued to you pursuant to the automatic
            reinvestment of income dividends or capital gains distributions.

CDSCs on    Unless a waiver applies, investors who purchase $1,000,000 or more
Class A     of Class A shares (and, thus, pay no initial sales charge) will be
Shares      subject to a 1% CDSC if the shares are redeemed within 18 months
            of their purchase. The Class A CDSC does not apply if you are
            otherwise eligible to purchase Class A shares without an initial
            sales charge or if you are eligible for a waiver of the CDSC. See
            "Reductions and Waivers of Initial Sales Charges and CDSCs" below.

--------------------------------------------------------------------------------
How CDSCs   A CDSC is imposed on redemptions of Class B and Class C shares
are         (and where applicable, Class A shares) on the amount of the
Calculated  redemption which causes the current value of your account for the
            particular class of shares of a Portfolio to fall below the total
            dollar amount of your purchase payments subject to the CDSC.
            However, no CDSC is imposed if the shares redeemed have been
            acquired through the reinvestment of dividends or capital gains
            distributions or if the amount redeemed is derived from increases
            in the value of your account above the amount of the purchase
            payments subject to the CDSC. CDSCs are deducted from the proceeds
            of your redemption, not from amounts remaining in your account. In
            determining whether a CDSC is payable, it is assumed that the
            purchase payment from which the redemption is made is the earliest
            purchase payment for the particular class of shares in your
            account (from which a redemption or exchange has not already been
            effected).

             For instance, the following example illustrates the operation of
            the Class B CDSC:

              .  Assume that an individual opens an account and makes a
                 purchase payment of $10,000 for Class B shares of a Portfolio
                 and that six months later the value of the investor's account
                 for that Portfolio has grown through investment performance
                 and reinvestment of distributions to $11,000. The investor
                 then may redeem up to $1,000 from that Portfolio ($11,000
                 minus $10,000) without incurring a CDSC. If the investor
                 should redeem $3,000, a CDSC would be imposed on $2,000 of
                 the redemption (the amount by which the investor's account
                 for the Portfolio was reduced below the amount of the
                 purchase payment). At the rate of 5%, the Class B CDSC would
                 be $100.

             In determining whether an amount is available for redemption
            without incurring a CDSC, the purchase payments made for all
            shares of a particular class of a Portfolio in the shareholder's
            account are aggregated, and the current value of all such shares
            is aggregated.

--------------------------------------------------------------------------------
Reductions  The initial sales charges on Class A shares and the CDSCs on Class
and         A, Class B and Class C shares may be reduced or waived under
Waivers     certain purchase arrangements and for certain categories of
of          investors. Please see the Guide for details. The Guide is
Initial     available free of charge from the Distributor. See "How to Buy and
Sales       Sell Shares--PIMCO Funds Shareholders' Guide" below.
Charges
and CDSCs

--------------------------------------------------------------------------------
DistributionThe Portfolios pay fees to the Distributor on an ongoing basis as
and         compensation for the services the Distributor renders and the
Servicing   expenses it bears in connection with the sale and distribution of
(12b-1)     Portfolio shares ("distribution fees") and/or in connection with
Plans       personal services rendered to Portfolio shareholders and the
            maintenance of shareholder accounts ("servicing fees"). These
            payments are made pursuant to Distribution and Servicing Plans
            ("12b-1 Plans") adopted by each Portfolio pursuant to Rule 12b-1
            under the Investment Company Act of 1940.

             There is a separate 12b-1 Plan for each class of shares offered
            in this Prospectus. Class A shares pay only servicing fees. Class
            B and Class C shares pay both distribution and servicing fees. The
            following lists the maximum annual rates at which the distribution
            and/or servicing fees may be paid under each 12b-1 Plan
            (calculated as a percentage of each Portfolio's average daily net
            assets attributable to the particular class of shares):

         All Portfolios                 Fee                                     Fee

            --------------------------------------------------------------------------------
</TABLE>

             Because 12b-1 fees are paid out of a Portfolio's assets on an
            ongoing basis, over time these fees will increase the cost of your
            investment and may cost you more than sales charges which are
            deducted at the time of investment. Therefore, although Class B
            and Class C shares do not pay initial sales charges, the
            distribution fees payable on Class B and Class C shares may, over
            time, cost you more than the initial sales charge imposed on Class
            A shares. Also, because Class B shares convert into Class A shares
            after they have been held for seven years and are not subject to
            distribution fees after the conversion, an investment in Class C
            shares may cost you more over time than an investment in Class B
            shares.

            How Portfolio Shares Are Priced

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

             The assets of each Portfolio consist of shares of the Underlying
            Funds, which are valued at their respective NAVs at the time of
            valuation of the Portfolios' shares. For purposes of calculating
            the NAV of Underlying Fund shares, portfolio securities and other
            assets of the Funds 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 quotes are not
            readily available may be valued, pursuant to procedures
            established by the Board of Trustees of the Underlying Fund, with
            reference to other securities or 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 Fund's Board of Trustees or persons acting at the Board's
            direction.

             Underlying Fund 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 an
            Underlying 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. As a result, to the extent that a Portfolio invests in
            Underlying Funds that hold foreign securities, the NAV of the
            Portfolio's shares may change at times when you can not purchase,
            redeem or exchange shares.

             Portfolio and Underlying 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 Underlying 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
            Underlying Funds or their 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 Underlying Funds may value securities at fair
            value or estimate their value as determined in good faith by the
            Fund's Board of Trustees or persons acting at their direction
            pursuant to procedures approved by the Board of Trustees. Fair
            valuation may also be used by the Underlying Fund's Board of
            Trustees if extraordinary events occur after the close of the
            relevant market but prior to the NYSE Close.

            How to Buy and Sell Shares

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

PIMCO
Funds
Shareholders'
Guide
            More detailed information about the Trust's purchase, sale and
            exchange arrangements for Portfolio shares is provided in the
            PIMCO Funds Shareholders' Guide, which is included in the
            Statement of Additional Information and can be obtained free of
            charge from the Distributor by written request or by calling 1-
            800-426-0107. The Guide provides technical information about the
            basic arrangements described below and also describes special
            purchase, sale and exchange features and programs offered by the
            Trust, including:

            .  Automated telephone and wire transfer procedures
            .  Automatic purchase, exchange and withdrawal programs
            .  Programs that establish a link from your Portfolio account to
               your bank account
            .  Special arrangements for tax-qualified retirement plans
            .  Investment programs which allow you to reduce or eliminate the
               initial sales charges on Class A shares
            .  Categories of investors that are eligible for waivers or
               reductions of initial sales charges and CDSCs

                                                                   Prospectus 32
<PAGE>

Calculation When you buy shares of the Portfolios, you pay a price equal to
of Share    the NAV of the shares, plus any applicable sales charge. When you
Price and   sell (redeem) shares, you receive an amount equal to the NAV of
Redemption  the shares, minus any applicable CDSC. NAVs are determined at the
Payments    close of regular trading (normally, 4:00 p.m., Eastern time) on
            the New York Stock Exchange on each day the New York Stock
            Exchange is open. See "How Portfolio Shares Are Priced" above for
            details. Generally, purchase and redemption orders for Portfolio
            shares are processed at the NAV next calculated after your order
            is received by the Distributor. There are certain exceptions where
            an order is received by a broker or dealer prior to the close of
            regular trading on the New York Stock Exchange and then
            transmitted to the Distributor after the NAV has been calculated
            for that day (in which case the order may be processed at that
            day's NAV). Please see the Guide for details.

             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 (at
            the succeeding day's NAV).

Buying      You can buy Class A, Class B or Class C shares of the Portfolios
Shares      in the following ways:

             . Through your broker, dealer or other financial intermediary.
            Your broker, dealer or other intermediary may establish higher
            minimum investment requirements than the Trust and may also
            independently charge you transaction fees and additional amounts
            (which may vary) in return for its services, which will reduce
            your return. Shares you purchase through your broker, dealer or
            other intermediary will normally be held in your account with that
            firm.

             . Directly from the Trust. To make direct investments, you must
            open an account with the Distributor and send payment for your
            shares either by mail or through a variety of other purchase
            options and plans offered by the Trust.

             The Trust accepts all purchases by mail subject to collection of
            checks at full value and conversion into federal funds. You may
            make subsequent purchases by mailing a check to the address above
            with a letter describing the investment or with the additional
            investment portion of a confirmation statement. Checks for
            subsequent purchases should be payable to PIMCO Funds Distributors
            LLC and should clearly indicate your account number. Please call
            the Distributor at 1-800-426-0107 if you have any questions
            regarding purchases by mail.

             The Guide describes a number of additional ways you can make
            direct investments, including through the PIMCO Funds Auto-Invest
            and PIMCO Funds Fund Link programs. You can obtain a Guide free of
            charge from the Distributor by written request or by calling 1-
            800-426-0107. See "PIMCO Funds Shareholders' Guide" above.

             The Distributor, in its sole discretion, may accept or reject any
            order for purchase of Portfolio shares. No share certificates will
            be issued unless specifically requested in writing.

Investment  The following investment minimums apply for purchases of Class A,
Minimums    Class B and Class C shares:

             Lower minimums may apply for certain categories of investors,
            including certain tax-qualified retirement plans, and for special
            investment programs and plans offered by the Trust, such as the
            PIMCO Funds Auto-Invest and PIMCO Funds Fund Link programs. Please
            see the Guide for details.

Small
Account
Fee
            Because of the disproportionately high costs of servicing accounts
            with low balances, if you have a direct account with the
            Distributor, you will be charged a fee at the annual rate of $16
            if your account balance for any Portfolio falls below a minimum
            level of $2,500, except for Uniform Gift to Minors, IRA, Roth IRA
            and Auto-Invest accounts for which the limit is $1,000. The fee
            also applies to employer-sponsored retirement plan accounts, Money
            Purchase and/or Profit Sharing plans, 401(k) plans, 403(b)(7)
            custodial accounts, SIMPLE IRAs, SEPs and SAR/SEPs. (A separate
            custodial fee may

33 PIMCO Funds: Multi-Manager Series
<PAGE>

            apply to IRAs, Roth IRAs and other retirement accounts.) However,
            you will not be charged this fee if the aggregate value of all of
            your PIMCO Funds accounts is at least $50,000. Any applicable
            small account fee will be deducted automatically from your below-
            minimum Portfolio account in quarterly installments and paid to
            the Administrator. Each Portfolio account will normally be valued,
            and any deduction taken, during the last five business days of
            each calendar quarter. Lower minimum balance requirements and
            waivers of the small account fee apply for certain categories of
            investors. Please see the Guide for details.

Minimum     Due to the relatively high cost to the Portfolios of maintaining
Account     small accounts, you are asked to maintain an account balance in
Size        each Portfolio in which you invest of at least the minimum
            investment necessary to open the particular type of account. If
            your balance for any Portfolio remains below the minimum for three
            months or longer, the Administrator has the right (except in the
            case of employer-sponsored retirement accounts) to redeem your
            remaining shares and close that Portfolio account after giving you
            60 days to increase your balance. Your Portfolio account will not
            be liquidated if the reduction in size is due solely to a decline
            in market value of your Portfolio shares or if the aggregate value
            of all your PIMCO Funds accounts exceeds $50,000.

Exchanging  You may exchange your Class A, Class B or Class C shares of any
Shares      Portfolio for the same Class of shares of any other Portfolio or
            of another series of the Trust or PIMCO Funds: Pacific Investment
            Management Series, subject to any restrictions on exchanges set
            forth in the applicable fund's or series' prospectus(es). 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. Exchanges are subject to the $2,500 minimum
            initial purchase requirements for each Portfolio, except with
            respect to tax-qualified programs and exchanges effected through
            the PIMCO Funds Auto-Exchange plan. In addition, an exchange is
            generally a taxable event which will generate capital gains or
            losses, and special rules may apply in computing tax basis when
            determining gain or loss. If you maintain your account with the
            Distributor, you may exchange shares by completing a written
            exchange request and sending it to PIMCO Funds Distributors LLC,
            P.O. Box 9688, Providence, RI 02940-0926. You can get an exchange
            form by calling the Distributor at 1-800-426-0107.

             The Trust reserves the right to refuse exchange purchases if, in
            the judgment of PIMCO Advisors, the purchase would adversely
            affect a Portfolio and its shareholders. In particular, a pattern
            of exchanges characteristic of "market-timing" strategies may be
            deemed by PIMCO Advisors to be detrimental to the Trust or a
            particular Portfolio. 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 Portfolio, subsequently exchanges those shares for
            shares of a different PIMCO Fund and then exchanges back into the
            originally purchased Portfolio. 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
            Portfolio) 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
            preceeding sentence, it reserves the right to do so at any time.
            Except as otherwise permitted by the Securities and Exchange
            Commission, the Trust will give you 60 days' advance notice if it
            exercises its right to terminate or materially modify the exchange
            privilege with respect to Class A, B and C shares.

             The Guide provides more detailed information about the exchange
            privilege, including the procedures you must follow and additional
            exchange options. You can obtain a Guide free of charge from the
            Distributor by written request or by calling 1-800-426-0107. See
            "PIMCO Funds Shareholders' Guide" above.

Selling     You can sell (redeem) Class A, Class B or Class C shares of the
Shares      Portfolios in the following ways:

              . Through your broker, dealer or other financial intermediary.
            Your broker, dealer or other intermediary may independently charge
            you transaction fees and additional amounts (which may vary) in
            return for its services, which will reduce your return.

              . Directly from the Trust by Written Request. To redeem shares
            directly from the Trust by written request (whether or not the
            shares are represented by certificates), you must send the
            following items to the Trust's Transfer Agent, PFPC, Inc., P.O.
            Box 9688, Providence, RI 02940-0926:

              (1) a written request for redemption signed by all registered
              owners exactly as the account is registered on the Transfer
              Agent's records, including fiduciary titles, if any, and
              specifying the account number and the dollar amount or number of
              shares to be redeemed;

                                                                   Prospectus 34
<PAGE>

              (2) for certain redemptions described below, a guarantee of all
              signatures on the written request or on the share certificate or
              accompanying stock power, if required, as described under
              "Signature Guarantee" below;

              (3) any share certificates issued for any of the shares to be
              redeemed (see "Certificated Shares" below); and

              (4) any additional documents which may be required by the
              Transfer Agent for redemption by corporations, partnerships or
              other organizations, executors, administrators, trustees,
              custodians or guardians, or if the redemption is requested by
              anyone other than the shareholder(s) of record. Transfers of
              shares are subject to the same requirements.

             A signature guarantee is not required for redemptions requested
            by and payable to all shareholders of record for the account that
            is to be sent to the address of record for that account. To avoid
            delay in redemption or transfer, if you have any questions about
            these requirements you should contact the Transfer Agent in
            writing or call 1-800-426-0107 before submitting a request.
            Written redemption or transfer requests will not be honored until
            all required documents in the proper form have been received by
            the Transfer Agent. You can not redeem your shares by written
            request to the Trust if they are held in broker "street name"
            accounts--you must redeem through your broker.

             If the proceeds of your redemption (i) are to be paid to a person
            other than the record owner, (ii) are to be sent to an address
            other than the address of the account on the Transfer Agent's
            records, or (iii) are to be paid to a corporation, partnership,
            trust or fiduciary, the signature(s) on the redemption request and
            on the certificates, if any, or stock power must be guaranteed as
            described under "Signature Guarantee" below. The Distributor may,
            however, waive the signature guarantee requirement for redemptions
            up to $2,500 by a trustee of a qualified retirement plan, the
            administrator for which has an agreement with the Distributor.

             The Guide describes a number of additional ways you can redeem
            your shares, including:

              . Telephone requests to the Transfer Agent
              . PIMCO Funds Automated Telephone System (ATS)
              . Expedited wire transfers
              . Automatic Withdrawal Plan
              . PIMCO Funds Fund Link

             Unless you specifically elect otherwise, your initial account
            application permits you to redeem shares by telephone subject to
            certain requirements. To be eligible for ATS, expedited wire
            transfer, Automatic Withdrawal Plan, and Fund Link privileges, you
            must specifically elect the particular option on your account
            application and satisfy certain other requirements. The Guide
            describes each of these options and provides additional
            information about selling shares. You can obtain a Guide free of
            charge from the Distributor by written request or by calling 1-
            800-426-0107.

             Other than an applicable CDSC, you will not pay any special fees
            or charges to the Trust or the Distributor when you sell your
            shares. However, if you sell your shares through your broker,
            dealer or other financial intermediary, that firm may charge you a
            commission or other fee for processing your redemption request.

             Redemptions of Portfolio shares may be suspended when trading on
            the New York Stock Exchange is restricted or during an emergency
            which makes it impracticable for the Portfolios or the Underlying
            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 payments for more than seven
            days, as permitted by law.

Timing of
Redemption
Payments
            Redemption proceeds will normally be mailed to the redeeming
            shareholder within seven calendar days or, in the case of wire
            transfer or Fund Link redemptions, sent to the designated bank
            account within one business day. Fund Link redemptions may be
            received by the bank on the second or third business day. In cases
            where shares have recently been purchased by personal check,
            redemption proceeds may be withheld until the check has been
            collected, which may take up to 15 days. To avoid such
            withholding, investors should purchase shares by certified or bank
            check or by wire transfer. Under unusual circumstances, the Trust
            may delay your redemption payments for more than seven days, as
            permitted by law.

Redemptions The Trust has agreed to redeem shares of each Portfolio solely in
In Kind     cash up to the lesser of $250,000 or 1% of the Portfolio'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
            Portfolio in lieu of cash. If your shares are redeemed in kind,
            you may incur transaction costs upon the disposition of the
            securities received in the distribution.

CertificatedIf you are redeeming shares for which certificates have been
Shares      issued, the certificates must be mailed to or deposited with the
            Trust, duly endorsed or accompanied by a duly endorsed stock power
            or by a written request for redemption. Signatures must be
            guaranteed as described under "Signature Guarantee" below. The
            Trust may request further documentation from institutions or
            fiduciary accounts, such as corporations, custodians (e.g., under
            the Uniform Gifts to Minors Act), executors, administrators,
            trustees or guardians. Your redemption request and stock power
            must be signed exactly as the account is registered, including
            indication of any special capacity of the registered owner.

Signature   When a signature guarantee is called for, you should have
Guarantee   "Signature Guaranteed" stamped under your signature and guaranteed
            by any of the following entities: U.S. banks, foreign banks having
            a U.S. correspondent bank, credit unions, savings associations,
            U.S. registered dealers and brokers, municipal securities dealers
            and brokers, government securities dealers and brokers, national
            securities exchanges, registered securities associations and
            clearing agencies (each an "Eligible Guarantor Institution"). The
            Distributor reserves the right to reject any signature guarantee
            pursuant to its written signature guarantee standards or
            procedures, which may permit it to reject signature guarantees
            from Eligible Guarantor Institutions that do not, based on credit
            guidelines, satisfy such written standards or procedures.

            Beginning January 1, 2001, when a signature guarantee is called
            for, a "medallion" signature guarantee will be required. A
            medallion signature guarantee may be obtained from a domestic bank
            or trust company, broker, dealer, clearing agency, savings
            association or other financial institution which is participating
            in a medallion program recognized by the Securities Transfer
            Association. The three recognized medallion programs are the
            Securities Transfer Agents Medallion Program (STAMP), Stock
            Exchanges Medallion Program (SEMP) and New York Stock Exchange,
            Inc. Medallion Signature Program (NYSE MSP). Signature guarantees
            from financial institutions which are not participating in a
            recognized medallion program may still be ineligible to provide a
            signature guarantee for transactions of greater than a specified
            dollar amount. The Trust may change the signature guarantee
            requirements from time to time upon notice to shareholders, which
            may be given by means of a new or supplemented Prospectus or a new
            or supplemented Guide. Shareholders should contact the Distributor
            for additional details regarding the Portfolios' signature
            guarantee requirements.

            Portfolio Distributions

            Each Portfolio distributes substantially all of its net investment
            income to shareholders in the form of dividends. You begin earning
            dividends on Portfolio shares the day after the Trust receives
            your purchase payment. Dividends paid by each Portfolio with
            respect to each class of shares are calculated in the same manner
            and at the same time, but dividends on Class B and Class C shares
            are expected to be lower than dividends on Class A shares as a
            result of the distribution fees applicable to Class B and Class C
            shares. The following shows when each Portfolio intends to declare
            and distribute income dividends to shareholders of record.

</TABLE>

             In addition, each Portfolio 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 36

             You can choose from the following distribution options:

            .  Reinvest all distributions in additional shares of the same
               class of your Portfolio at NAV. This will be done unless you
               elect another option.

            .  Invest all distributions in shares of the same class of any
               other Portfolio or another series of the Trust or PIMCO Funds:
               Pacific Investment Management Series which offers that class at
               NAV. You must have an account existing in the Portfolio or
               series selected for investment with the identical registered
               name. You must elect this option on your account application or
               by a telephone request to the Transfer Agent at 1-800-426-0107.

            .  Receive all distributions in cash (either paid directly to you
               or credited to your account with your broker or other financial
               intermediary). You must elect this option on your account
               application or by a telephone request to the Transfer Agent at
               1-800-426-0107.

             You do not pay any sales charges on shares you receive through
            the reinvestment of Portfolio distributions.

             If you elect to receive Portfolio 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.

             For further information on distribution options, please contact
            your broker or call the Distributor at 1-800-426-0107.

            Tax Consequences

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

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

             Portfolio distributions are taxable to you even if they are paid
            from income or gains earned by a Portfolio 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 Portfolio distribution, you will pay full price
            for the shares and may receive a portion of your investment back
            as a taxable distribution.

             The Portfolios' use of a fund of funds structure could affect the
            amount, timing and character of distributions to shareholders. See
            "Taxation--Distributions" in the Statement of Additional
            Information.

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

             This section relates only to federal income tax consequences of
            investing in the Portfolios; the consequences under other tax laws
            may differ. You should consult your tax advisor as to the possible
            application of foreign, state and local income tax laws to
            Portfolio dividends and capital distributions. Please see the
            Statement of Additional Information for additional information
            regarding the tax aspects of investing in the Portfolios.

            Financial Highlights

            The financial highlights table is intended to help you understand
            the financial performance of Class A, Class B and Class C shares
            of each Portfolio since the class of shares was first offered.
            Certain information reflects financial results for a single
            Portfolio share. The total returns in the table represent the rate
            that an investor would have earned or lost on an investment in a
            particular class of shares of a Portfolio, assuming reinvestment
            of all dividends and distributions. This information has been
            audited by PricewaterhouseCoopers LLP, whose report, along with
            each Portfolio's financial statements, are included in the Trust's
            annual report to shareholders. The annual report is incorporated
            by reference in the Statement of Additional Information and is
            available free of charge upon request from the Distributor.

Fund
Descriptions,
Performance
and Fees

             It is possible to lose money on investments in the Funds. The
            fact that a Fund may have had good performance in the past (for
            example, during the year ended 1999) is no assurance that the
            value of the Fund's investments will not decline in the future or
            appreciate at a slower rate. An investment in a Fund is not a
            deposit of a bank and is not insured or guaranteed by the Federal
            Deposit Insurance Corporation or any other government agency.

                                  40-50

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in income-producing (e.g.,
            dividend-paying) common stocks of companies with market
            capitalizations of more than $2 billion at the time of investment.

             The Fund's initial selection universe consists of the 1,000
            largest publicly traded companies (in terms of market
            capitalization) in the U.S. The portfolio managers classify the
            universe by industry. They then identify the most undervalued
            stocks in each industry based mainly on relative P/E ratios,
            calculated both with respect to trailing operating earnings and
            forward earnings estimates. From this group of stocks, the Fund
            buys approximately 25 stocks with the highest dividend yields. The
            portfolio managers then screen the most undervalued companies in
            each industry by dividend yield to identify the highest yielding
            stocks in each industry. From this group, the Fund buys
            approximately 25 additional stocks with the lowest P/E ratios.

             In selecting stocks, the portfolio managers consider quantitative
            factors such as price momentum (based on changes in stock price
            relative to changes in overall market prices), earnings momentum
            (based on analysts' earnings per share estimates and revisions to
            those estimates), relative dividend yields, valuation relative to
            the overall market and trading liquidity. The portfolio managers
            may replace a stock when a stock within the same industry group
            has a considerably higher dividend yield or lower valuation than
            the Fund's current holding.

             Under normal circumstances, the Fund intends to be fully invested
            in common stocks (aside from certain cash management practices).
            The Fund may temporarily hold up to 10% of its assets in cash and
            cash equivalents for defensive purposes in response to unfavorable
            market and other conditions. This would be inconsistent with the
            Fund's investment objective and principal strategies.

-------------------------------------------------------------------------------
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          . Value Securities Risk
                                                          . Management Risk
              . Issuer Risk          . Credit 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 Fund does not yet have a full calendar year of performance.
Information Thus, no bar chart or average annual total returns table is
            included for the Fund.

            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 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 at least 65% of its assets in common stocks of companies
            with market capitalizations of more than $2 billion at the time of
            investment and below average P/E ratios relative to the market and
            their respective industry groups. To achieve income, the Fund
            invests a portion of its assets in income-producing (e.g.,
            dividend-paying) common stocks.

             The Fund's initial selection universe consists of the 1,000
            largest publicly traded companies (in terms of market
            capitalization) in the U.S. The portfolio managers classify the
            universe by industry. They then identify the most undervalued
            stocks in each industry based mainly on relative P/E ratios,
            calculated both with respect to trailing operating earnings and
            forward earnings estimates. After narrowing this universe to
            approximately 150 candidates, the portfolio managers select
            approximately 40 stocks for the Fund, each representing a
            different industry group. The portfolio managers select stocks
            based on a quantitative analysis of factors including price
            momentum (based on changes in stock price relative to changes in
            overall market prices), earnings momentum (based on analysts'
            earnings per share estimates and revisions to those estimates),
            relative dividend yields, valuation relative to the overall market
            and trading liquidity. The Fund's portfolio is generally
            rebalanced quarterly. The portfolio managers may also replace a
            stock when a stock within the same industry group has a
            considerably lower valuation than the Fund's current holding.

             Under normal circumstances, the Fund intends to be fully invested
            in common stocks (aside from certain cash management practices).
            The Fund may temporarily hold up to 10% of its assets in cash and
            cash equivalents for defensive purposes in response to unfavorable
            market and other conditions. This would be inconsistent with the

            cost of investing in Institutional Class or Administrative Class
            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 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 at least 65% of its assets in common stocks of companies
            with market capitalizations of between $1 billion and $5 billion
            at the time of investment and below average P/E ratios relative to
            their respective industry groups. The Fund normally invests in
            approximately 25 common stocks. To achieve income, the Fund
            invests a portion of its assets in income-producing (e.g.,
            dividend-paying) common stocks.

              The Fund's initial selection universe consists of approximately
            600 stocks of companies within the Fund's capitalization range.
            The portfolio managers classify the universe by industry. They
            then identify the most undervalued stocks in each industry based
            mainly on relative P/E ratios, calculated both with respect to
            trailing operating earnings and forward earnings estimates. The
            portfolio managers then select approximately 25 stocks, each
            representing a different industry group. Each stock has close to
            equal weighting in the portfolio. The portfolio managers select
            stocks based on an analysis of factors including price momentum
            (based on changes in stock price relative to changes in overall
            market prices), earnings momentum (based on analysts' earnings per
            share estimates and revisions to those estimates), relative
            dividend yields and trading liquidity. The Fund's portfolio is
            generally rebalanced quarterly. The portfolio managers may also
            replace a stock when a stock within the same industry group has a
            considerably lower valuation than the Fund's current holding.

              Under normal circumstances, the Fund intends to be fully
            invested in common stocks (aside from certain cash management
            practices). The Fund may temporarily hold up to 25% of its assets
            in cash and cash equivalents for defensive purposes in response to
            unfavorable market and other conditions. This would be
            inconsistent with the Fund's investment objective and principal
            strategies.

--------------------------------------------------------------------------------
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        . Smaller Company Risk      . Credit Risk
            . Issuer Risk        . Liquidity Risk            . Management Risk

            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 summarized 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
            each 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.

Market      The market price of securities owned by a Fund may go up or down,
Risk        sometimes rapidly or unpredictably. Each of the Funds normally
            invests most of its assets in common stocks and/or other equity
            securities. A principal risk of investing in each Fund is that the
            equity securities in its portfolio will decline in value due to
            factors affecting equity securities markets generally or
            particular industries represented in those markets. The values of
            equity securities 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 also decline for a number of reasons
Risk        which directly relate to the issuer, such as management
            performance, financial leverage and reduced demand for the
            issuer's goods or services.

Value       The Funds place particular emphasis on investing in securities of
Securities  companies that may not be expected to experience significant
Risk        earnings growth, but whose securities its portfolio manager
            believes are selling at a price lower than their true value (value
            securities). Companies that issue value securities may have
            experienced adverse business developments or may be subject to
            special risks that have caused their securities to be out of
            favor. If a portfolio manager's assessment of a company's
            prospects is wrong, or if the market does not recognize the value
            of the company, the price of its securities may decline or may not
            approach the value that the portfolio manager anticipates.

Smaller     The general risks associated with equity securities and liquidity
Company     risk are particularly pronounced for securities of companies with
Risk        smaller market capitalizations. These companies may have limited
            product lines, markets or financial resources or they may depend
            on a few key employees. Securities of smaller companies may trade
            less frequently and in lesser volume than more widely held
            securities and their values may fluctuate more sharply than other
            securities. They may also trade in the over-the-counter market or
            on a regional exchange, or may otherwise have limited liquidity.
            The NFJ Value 25 Fund may have significant exposure to this risk
            because it invests substantial assets in companies with medium-
            sized market capitalizations, which are smaller and generally
            less-seasoned than the largest companies.

Liquidity   All of the Funds are subject to liquidity risk. Liquidity risk
Risk        exists when particular investments are difficult to purchase or
            sell, possibly preventing a Fund from selling such illiquid
            securities at an advantageous time or price. Funds with principal
            investment strategies that involve securities of companies with
            smaller market capitalizations, foreign securities, derivatives or
            securities with substantial market and/or credit risk tend to have
            the greatest exposure to liquidity risk.

Focused
Investment  Focusing Fund investments in a small number of issuers, industries
Risk        or foreign currencies increases risk. Funds, such as the NFJ Value
            25 Fund, that invest in a relatively small number of issuers may
            have more risk because changes in the value of a single security
            or the impact of a single economic, political or regulatory
            occurrence may have a greater adverse impact on the Fund's net
            asset value. Some of those issuers also may present substantial
            credit or other risks. Also, the Funds may from time to time have
            greater risk to the extent they invest a substantial portion of
            their assets in companies in related industries such as
            "technology" or "financial and business services," which may share
            common characteristics, are often subject to similar business
            risks and regulatory burdens, and whose securities may react
            similarly to economic, market, political or other developments.

Credit      All of the Funds are subject to credit risk. This is the risk that
Risk        the issuer or the guarantor of a fixed income security, or the
            counterparty to a 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 their credit ratings.

Management  Each Fund is subject to management risk because it is an actively
Risk        managed investment portfolio. PIMCO Advisors, NFJ 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.

            PIMCO Advisors serves as the investment adviser and the
            administrator (serving in its capacity as administrator, the
            "Administrator") for the Funds. Subject to the supervision of the
            Board of Trustees, PIMCO Advisors is responsible for managing,
            either directly or through others selected by it, the investment
            activities of the Funds and the Funds' business affairs and other
            administrative matters.

             PIMCO Advisors is located at 800 Newport Center Drive, Newport
            Beach, California 92660. Organized in 1987, PIMCO Advisors
            provides investment management and advisory services to private
            accounts of institutional and individual clients and to mutual
            funds. As of September 30, 2000, PIMCO Advisors and its subsidiary
            partnerships had approximately $272 billion in assets under
            management.

             PIMCO Advisors has retained an affiliated investment management
            firm, NFJ Investment Group ("NFJ" or the "Sub-Adviser") to manage
            each Fund's investments. See "Sub-Adviser" below. PIMCO Advisors
            has retained its affiliate, Pacific Investment Management Company
            LLC ("Pacific Investment Management Company"), to provide various
            administrative and other services required by the Funds in its
            capacity as sub-administrator. PIMCO Advisors and the sub-
            administrator may retain other affiliates to provide certain of
            these services.

Advisory    Each Fund pays PIMCO Advisors fees in return for providing or
Fees        arranging for the provision of investment advisory services. PIMCO
            Advisors (and not the Funds) pays a portion of the advisory fees
            it receives to NFJ in return for NFJ's services as Sub-Adviser.

             The Funds pay monthly advisory fees to PIMCO Advisors at the
            following annual rates (stated as a percentage of the average
            daily net assets of each Fund taken separately):

Administrative
Fees

            Each Fund pays for the administrative services it requires under a
            fee structure which is essentially fixed. Institutional and
            Administrative Class shareholders of each Fund pay an
            administrative fee to PIMCO Advisors, computed as a percentage of
            the Fund's assets attributable in the aggregate to those classes
            of shares. PIMCO Advisors, in turn, provides or procures
            administrative services for Institutional and Administrative Class
            shareholders and also bears the costs of most third-party services
            required by the Funds, including audit, custodial, portfolio
            accounting, legal, transfer agency and printing costs. The Funds
            do bear other expenses which are not covered under the
            administrative fee which may vary and affect the total level of
            expenses paid by Institutional and Administrative Class
            shareholders, such as brokerage fees, commissions and other
            transaction expenses, costs of borrowing money, including interest
            expenses, and fees and expenses of the Trust's disinterested
            Trustees.

             Institutional and Administrative Class shareholders of the Funds
            pay PIMCO Advisors monthly administrative fees at the annual rate
            of 0.25% (stated as a percentage of the average daily net assets
            attributable in the aggregate to the Fund's Institutional and
            Administrative Class shares):

Distributor The Trust's Distributor is PIMCO Funds Distributors LLC, 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.

Adviser/
Sub-        Shareholders of each Fund have approved a proposal permitting
Adviser     PIMCO Advisors to enter into new or amended sub-advisory
Relationshipagreements with one or more sub-advisers with respect to each Fund
            without obtaining shareholder approval of such agreements, subject
            to the conditions of an exemptive order that has been granted by
            the Securities and Exchange Commission. One of the conditions
            requires the Board of Trustees to approve any such agreement. In
            addition, the exemptive order prohibits PIMCO Advisors from
            entering into sub-advisory agreements with affiliates of PIMCO
            Advisors without shareholder approval, unless those affiliates are
            substantially wholly-owned by PIMCO Advisors. PIMCO Advisors has
            the ultimate responsibility to to oversee the Sub-Adviser and to
            recommend its hiring, termination and replacement.

                                                                   Prospectus12
<PAGE>

            Investment Options --
            Institutional Class and Administrative Class Shares

            The Trust offers investors Institutional Class and Administrative
            Class shares of the Funds in this Prospectus.

             The Trust does not charge any sales charges (loads) or other fees
            in connection with purchases, sales (redemptions) or exchanges of
            Institutional Class or Administrative Class shares. See
            "Purchases, Redemptions and Exchanges" below.

             Administrative Class shares are generally subject to a higher
            level of operating expenses than Institutional Class shares due to
            the additional service and/or distribution fees paid by
            Administrative Class shares as described below. Therefore,
            Institutional Class shares will generally pay higher dividends and
            have a more favorable investment return than Administrative Class
            shares.

              . Service and Distribution (12b-1) Fees--Administrative Class
            Shares. The Trust has adopted both an Administrative Services Plan
            and a Distribution Plan for the Administrative Class shares of
            each Fund. Each Plan has been adopted in accordance with the
            requirements of Rule 12b-1 under the Investment Company Act of
            1940 and is administered in accordance with that rule. However,
            shareholders do not have the voting rights set forth in Rule 12b-1
            with respect to the Administrative Services Plan.

             Each Plan allows the Funds to use its Administrative Class assets
            to reimburse financial intermediaries that provide services
            relating to Administrative Class shares. The Distribution Plan
            permits reimbursement for expenses in connection with the
            distribution and marketing of Administrative Class shares and/or
            the provision of shareholder services to Administrative Class
            shareholders. The Administrative Services Plan permits
            reimbursement for services in connection with the administration
            of plans or programs that use Administrative Class shares of the
            Funds as their funding medium and for related expenses.

             In combination, the Plans permit a Fund to make total
            reimbursements at an annual rate of up to 0.25% of the Fund's
            average daily net assets attributable to its Administrative Class
            shares. The same entity may not receive both distribution and
            administrative services fees with respect to the same
            Administrative Class assets, but may receive fees under each Plan
            with respect to separate assets. Because these fees are paid out
            of a Fund's Administrative Class assets on an ongoing basis, over
            time they will increase the cost of an investment in
            Administrative Class shares and may cost an investor more than
            other types of sales charges.

              . Arrangements with Service Agents. Institutional Class and
            Administrative Class shares of the Funds may 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 and/or
            distribution fees paid with respect to Administrative Class
            shares. Service agents may impose additional or different
            conditions than the Trust on purchases, redemptions or exchanges
            of Fund shares by their customers. Service agents may also
            independently establish and charge their customers transaction
            fees, account fees and other amounts in connection with purchases,
            sales and redemptions of Fund shares in addition to any fees
            charged by the Trust. These additional fees may vary over time and
            would increase the cost of the customer's investment and lower
            investment returns. 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, redemptions and exchanges. Shareholders who
            are customers of service agents should consult their service
            agents for information regarding these fees and conditions.

            Purchases, Redemptions and Exchanges

Purchasing  Investors may purchase Institutional Class and Administrative
Shares      Class shares of the Funds at the relevant net asset value ("NAV")
            of that class without a sales charge or other fee.

             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 their
            customers' investments in the Funds.

             Administrative Class shares are offered primarily through
            employee benefit plan alliances, broker-dealers and other
            intermediaries, and each Fund pays service and/or distribution
            fees to these entities for services they provide to Administrative
            Class shareholders.

             Pension and profit-sharing plans, employee benefit trusts and
            employee benefit plan alliances and "wrap account" programs
            established with broker-dealers or financial intermediaries may
            purchase shares of either class only if the plan or program for
            which the shares are being acquired will maintain an omnibus or
            pooled account for each Fund and will not require a Fund to pay
            any type of administrative payment per participant account to any
            third party.

              . Investment Minimums. The minimum initial investment for shares
            of either class is $5 million, except that the minimum initial
            investment for a registered investment adviser purchasing
            Institutional Class shares for its clients through omnibus
            accounts is $250,000 per Fund. At the discretion of PIMCO
            Advisors, the minimum initial investment may be waived for
            Institutional or Administrative Class shares offered to clients of
            PIMCO Advisors, NFJ and their affiliates. In addition, the minimum
            initial investment does not apply to Institutional Class shares
            offered through fee-based programs sponsored and maintained by a
            registered broker-dealer and approved by the Distributor in which
            each investor pays an asset based fee at an annual rate of at
            least 0.50% of the assets in the account to a financial
            intermediary for investment advisory and/or administrative
            services.

             The Trust and the Distributor may waive the minimum initial
            investment for other categories of investors at their discretion.

              . Timing of Purchase Orders and Share Price Calculations. A
            purchase order received by the Trust's transfer agent, National
            Financial Data Services (the "Transfer Agent"), prior to the close
            of regular trading (normally 4:00 p.m., Eastern time) on the New
            York Stock Exchange, on a day the Trust is open for business,
            together with payment made in one of the ways described below,
            will be effected at that day's net asset value ("NAV"). An order
            received after the close of regular trading on the New York Stock
            Exchange will be effected at the NAV determined on the next
            business day. However, orders received by certain retirement plans
            and other financial intermediaries on a business day prior to the
            close of regular trading on the New York Stock Exchange and
            communicated to the Transfer Agent prior to 9:00 a.m., Eastern
            time, on the following business day will be effected at the NAV
            determined on the prior business day. The Trust is "open for
            business" on each day the New York Stock Exchange is open for
            trading, which excludes the following holidays: New Year's Day,
            Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
            Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
            Christmas Day. Purchase orders will be accepted only on days on
            which the Trust is open for business.

              . Initial Investment. Investors may open an account by
            completing and signing a Client Registration Application and
            mailing it to PIMCO Funds at 840 Newport Center Drive, Suite 300,

                                                                   Prospectus 14
<PAGE>

             Except as described below, an investor may purchase Institutional
            Class and Administrative Class shares only by wiring federal funds
            to the Transfer Agent, National Financial Data Services, 330 West
            9th Street, 4th Floor, Kansas City, Missouri 64105. Before wiring
            federal funds, the investor must telephone the Trust at 1-800-927-
            4648 to receive instructions for wire transfer and must provide
            the following information: name of authorized person, shareholder
            name, shareholder account number, name of Fund and share class,
            amount being wired, and wiring bank name.

             An investor may purchase shares without first wiring federal
            funds if the proceeds of the investment are derived from an
            advisory account the investor maintains with PIMCO Advisors or one
            of its affiliates or from an investment by broker-dealers,
            institutional clients or other financial intermediaries which have
            established a shareholder servicing relationship with the Trust on
            behalf of their customers.

              . Additional Investments. An investor may purchase additional
            Institutional Class and Administrative Class shares of the Funds
            at any time by calling the Trust and wiring federal funds to the
            Transfer Agent as outlined above.

              . Other Purchase Information. Purchases of a Fund's
            Institutional Class and Administrative Class shares will be made
            in full and fractional shares. In the interest of economy and
            convenience, certificates for shares will not be issued.

             The Trust and the Distributor each reserves the right, in its
            sole discretion, to suspend the offering of shares of the Funds or
            to reject any purchase order, in whole or in part, when, in the
            judgment of management, such suspension or rejection is in the
            best interests of the Trust.

             An investor should invest in the Funds for long-term investment
            purposes only. The Trust, PIMCO Advisors and NFJ each reserve the
            right to restrict purchases of Fund shares (including exchanges)
            when a pattern of frequent purchases and sales made in response to
            short-term fluctuations in share price appears evident. Notice of
            any such restrictions, if any, will vary according to the
            particular circumstances.

             Institutional Class and Administrative Class shares of the Trust
            may not be qualified or registered for sale in all states.
            Investors should inquire as to whether shares of a particular Fund
            are available for offer and sale in the investor's state of
            residence. Shares of the Trust may not be offered or sold in any
            state unless registered or qualified in that jurisdiction or
            unless an exemption from registration or qualification is
            available.

             Subject to the approval of the Trust, an investor may purchase
            shares of a Fund with liquid securities that are eligible for
            purchase by the Fund (consistent with the Fund's investment
            policies and restrictions) and that have a value that is readily
            ascertainable in accordance with the Trust's valuation policies.
            These transactions will be effected only if PIMCO Advisors or NFJ
            intends to retain the security in the Fund as an investment.
            Assets purchased by a Fund in such a transaction will be valued in
            generally the same manner as they would be valued for purposes of
            pricing the Fund's shares, if such assets were included in the
            Fund's assets at the time of purchase. The Trust reserves the
            right to amend or terminate this practice at any time.

              . Retirement Plans. Shares of the Funds are available for
            purchase by retirement and savings plans, including Keogh plans,
            401(k) plans, 403(b) custodial accounts, and Individual Retirement
            Accounts. The administrator of a plan or employee benefits office
            can provide participants or employees with detailed information on
            how to participate in the plan and how to elect a Fund as an
            investment option. Participants in a retirement or savings plan
            may be permitted to elect different investment options, alter the
            amounts contributed to the plan, or change how contributions are
            allocated among investment options in accordance with the plan's
            specific provisions. The plan administrator or employee benefits
            office should be consulted for

15 PIMCO Funds: Multi-Manager Series
<PAGE>

            details. For questions about participant accounts, participants
            should contact their employee benefits office, the plan
            administrator, or the organization that provides recordkeeping
            services for the plan. Investors who purchase shares through
            retirement plans should be aware that plan administrators may
            aggregate purchase and redemption orders for participants in the
            plan. Therefore, there may be a delay between the time the
            investor places an order with the plan administrator and the time
            the order is forwarded to the Transfer Agent for execution.

Redeeming     . Redemptions by Mail. An investor may redeem (sell)
Shares      Institutional Class and Administrative Class shares by submitting
            a written request to PIMCO Funds at 840 Newport Center Drive,
            Suite 300, Newport Beach, California 92660. The redemption request
            should state the Fund from which the shares are to be redeemed,
            the class of shares, the number or dollar amount of the shares to
            be redeemed and the account number. The request must be signed
            exactly as the names of the registered owners appear on the
            Trust's account records, and the request must be signed by the
            minimum number of persons designated on the Client Registration
            Application that are required to effect a redemption.

              . Redemptions by Telephone or Other Wire Communication. An
            investor that elects this option on the Client Registration
            Application (or subsequently in writing) may request redemptions
            of shares by calling the Trust at 1-800-927-4648, by sending a
            facsimile to 1-949-725-6830, by sending an e-mail to
            [email protected], or by other means of wire
            communication. Investors should state the Fund and class from
            which the shares are to be redeemed, the number or dollar amount
            of the shares to be redeemed, the account number and the signature
            (which may be an electronic signature) of an authorized signatory.
            Redemption requests of an amount of $10 million or more may be
            initiated by telephone, wire or e-mail, but must be confirmed in
            writing by an authorized party prior to processing.

             In electing a telephone redemption, the investor authorizes
            Pacific Investment Management Company and the Transfer Agent to
            act on telephone instructions from any person representing himself
            to be the investor, and reasonably believed by Pacific Investment
            Management Company or the Transfer Agent to be genuine. Neither
            the Trust nor the Transfer Agent may be liable for any loss, cost
            or expense for acting on instructions (whether in writing or by
            telephone) believed by the party receiving such instructions to be
            genuine and in accordance with the procedures described in this
            Prospectus. Shareholders should realize that by electing the
            telephone, wire or e-mail redemption option, they may be giving up
            a measure of security that they might have if they were to redeem
            their shares in writing. Furthermore, interruptions in service may
            mean that a shareholder will be unable to effect a redemption by
            telephone or e-mail when desired. The Transfer Agent also provides
            written confirmation of transactions initiated by telephone as a
            procedure designed to confirm that telephone instructions are
            genuine (written confirmation is also provided for redemption
            requests received in writing or via e-mail). All telephone
            transactions are recorded, and Pacific Investment Management
            Company or the Transfer Agent may request certain information in
            order to verify that the person giving instructions is authorized
            to do so. The Trust or Transfer Agent may be liable for any losses
            due to unauthorized or fraudulent telephone transactions if it
            fails to employ reasonable procedures to confirm that instructions
            communicated by telephone are genuine. All redemptions, whether
            initiated by letter or telephone, will be processed in a timely
            manner, and proceeds will be forwarded by wire in accordance with
            the redemption policies of the Trust detailed below. See "Other
            Redemption Information."

             Shareholders may decline telephone exchange or redemption
            privileges after an account is opened by instructing the Transfer
            Agent in writing at least seven business days prior to the date
            the instruction is to be effective. Shareholders may experience
            delays in exercising telephone redemption privileges during
            periods of abnormal market activity. During periods of volatile
            economic or market conditions, shareholders may wish to consider
            transmitting redemption orders by telegram, facsimile or overnight
            courier.

                                                                   Prospectus 16
<PAGE>

             Defined contribution plan participants may request redemptions by
            contacting the employee benefits office, the plan administrator or
            the organization that provides recordkeeping services for the
            plan.

              . Other Redemption Information. Redemption requests for Fund
            shares are effected at the NAV per share next determined after
            receipt of a redemption request by the Trust or its designee. The
            request must properly identify all relevant information, such as
            account number, redemption amount (in dollars or shares) and the
            Fund name, and must be executed or initialed by the appropriate
            signatories. A redemption request received by the Trust or its
            designee prior to the close of regular trading on the New York
            Stock Exchange (normally 4:00 p.m., Eastern time), on a day the
            Trust is open for business, is effective on that day. A redemption
            request received after that time becomes effective on the next
            business day.

             Redemption proceeds will ordinarily be wired to the investor's
            bank within three business days after the redemption request, but
            may take up to seven business days. Redemption proceeds will be
            sent by wire only to the bank name designated on the Client
            Registration Application. The Trust may suspend the right of
            redemption or postpone the payment date at times when the New York
            Stock Exchange is closed, or during certain other periods as
            permitted under the federal securities laws.

             For shareholder protection, a request to change information
            contained in an account registration (for example, a request to
            change the bank designated to receive wire redemption proceeds)
            must be received in writing, signed by the minimum number of
            persons designated on the Client Registration Application that are
            required to effect a redemption, and accompanied by a signature
            guarantee from any eligible guarantor institution, as determined
            in accordance with the Trust's procedures. Shareholders should
            inquire as to whether a particular institution is an eligible
            guarantor institution. A signature guarantee cannot be provided by
            a notary public. In addition, corporations, trusts, and other
            institutional organizations are required to furnish evidence of
            the authority of the persons designated on the Client Registration
            Application to effect transactions for the organization.

             Due to the relatively high cost of maintaining small accounts,
            the Trust reserves the right to redeem Institutional Class and
            Administrative Class shares in any account for their then-current
            value (which will be promptly paid to the investor) if at any
            time, due to redemption by the investor, the shares in the account
            do not have a value of at least $100,000. A shareholder will
            receive advance notice of a mandatory redemption and will be given
            at least 30 days to bring the value of its account up to at least
            $100,000.

             The Trust agrees to redeem shares of each Fund solely in cash 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 reserves
            the right to 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 shares would ever
            be redeemed in kind. When shares are redeemed in kind, the
            redeeming shareholder should expect to incur transaction costs
            upon the disposition of the securities received in the
            distribution.

             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.

Exchange
Privilege
            An investor may exchange Institutional Class or Administrative
            Class shares of a Fund described in this prospectus for shares of
            the same class of any other Fund described in this prospectus
            based on the respective NAVs of the shares involved. An exchange
            may be made by following the redemption procedure described

17 PIMCO Funds: Multi-Manager Series
<PAGE>

            above under "Redemptions by Mail" or, if the investor has elected
            the telephone redemption option, by calling the Trust at 1-800-
            927-4648.

             An investor may exchange shares only with respect to Funds or
            other eligible series that are registered in the investor's state
            of residence or where an exemption from registration is available.
            In addition, an exchange is generally a taxable event which will
            generate capital gains or losses, and special rules may apply in
            computing tax basis when determining gain or loss. See "Tax
            Consequences" in this Prospectus and "Taxation" in the Statement
            of Additional Information.

             The Trust reserves the right to refuse exchange purchases if, in
            the judgment of PIMCO Advisors, 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 Advisors to be detrimental to the Trust or a
            particular Fund. The Trust reserves the right to impose additional
            restrictions on exchanges at any time, although it will attempt to
            give shareholders 30 days' prior notice whenever it is reasonably
            able to do so.

            How Fund Shares Are Priced

            The net asset value ("NAV") of a Fund's Institutional and
            Administrative Class 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 the 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 quotes are not readily
            available may be valued, pursuant to procedures established by the
            Board of Trustees, with reference to other securities or 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 their 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 or persons acting at their direction pursuant to
            procedures approved by the Board of Trustees. Fair valuation may
            also be used by the Board of Trustees if extraordinary events
            occur after the close of the relevant market but prior to the NYSE
            Close.

                                                                   Prospectus 18
<PAGE>

             Under certain circumstances, the per share NAV of the
            Administrative Class shares of the Funds may be lower than the per
            share NAV of the Institutional Class shares as a result of the
            daily expense accruals of the service and/or distribution fees
            paid by Administrative Class 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 the two classes.

            Fund Distributions

            Each Fund distributes substantially all of its net investment
            income to shareholders in the form of dividends. A shareholder
            begins earning dividends on Fund shares the day after the Trust
            receives the shareholder's 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, but dividends on
            Administrative Class shares are expected to be lower than
            dividends on Institutional Class shares as a result of the service
            and/or distribution fees applicable to Administrative Class
            shares.

             The NFJ Equity Income and NFJ Value Funds each intend to declare
            and distribute income dividends to shareholders of record at least
            quarterly. The NFJ Value 25 Fund intends to declare and distribute
            income dividends to shareholders of record at least annually. 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.

             A Fund's dividend and capital gain distributions with respect to
            a particular class of shares will automatically be reinvested in
            additional shares of the same class of the Fund at NAV unless the
            shareholder elects to have the distributions paid in cash. A
            shareholder may elect to have distributions paid in cash on the
            Client Registration Application or by submitting a written
            request, signed by the appropriate signatories, indicating the
            account number, Fund name(s) and wiring instructions. Shareholders
            do not pay any sales charges or other fees on the receipt of
            shares received through the reinvestment of Fund distributions.

             For further information on distribution options, please contact
            the Trust at 1-800-927-4648.

            Tax Consequences

              . Taxes on Fund Distributions. A shareholder subject to U.S.
            federal income tax will be subject to tax on Fund distributions
            whether they are paid in cash or reinvested in additional shares
            of the Funds. For federal income tax purposes, Fund distributions
            will be taxable to the shareholder as either ordinary income or
            capital gains.

             Fund dividends (i.e., distributions of investment income) are
            taxable to shareholders 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 the
            shareholder owned the shares. Distributions of gains from
            investments that a Fund owned for more than 12 months will
            generally be taxable to shareholders as capital gains.
            Distributions of gains from investments that the Fund owned for 12
            months or less will generally be taxable as ordinary income.

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


19 PIMCO Funds: Multi-Manager Series
<PAGE>

              . Taxes on Redemptions or Exchanges of Shares. Any gain
            resulting from the sale of Fund shares will generally be subject
            to federal income tax. When a shareholder exchanges shares of a
            Fund for shares of another series, the transaction generally 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.

              . A Note on Foreign Investments. A Fund's investments in foreign
            securities, if any, may be subject to foreign withholding taxes.
            In that case, the Fund's yield on those securities would be
            decreased. In addition, a Fund's investments in foreign securities
            or foreign currencies may increase or accelerate the Fund's
            recognition of ordinary income and may affect the timing or amount
            of the Fund's distributions.

             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
            local income tax laws to Fund dividends and capital distributions.
            Please see the Statement of Additional Information for additional
            information regarding the tax aspects of investing in the Funds.

            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 identified
            under "Summary Information" above. It also describes
            characteristics and risks of additional securities and investment
            techniques that are not necessarily principal investments or
            strategies but may be used by the Funds from time to time. Most of
            these securities and investment techniques are discretionary,
            which means that the portfolio managers 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 must rely on the professional investment judgment and skill
            of the Funds' Adviser and Sub-Adviser 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.

Fixed       Fixed income securities are obligations of the issuer to make
Income      payments of principal and/or interest on future dates, and include
Securities  corporate and government bonds, notes, certificates of deposit,
and         commercial paper, convertible securities and mortgage-backed and
Defensive   other asset-backed securities.
Strategies

             Under normal circumstances, the Funds intend to be fully invested
            in common stocks (aside from cash management practices), except
            that each of the Funds may temporarily hold up to 10% of its
            assets in cash and cash equivalents for defensive purposes in
            response to unfavorable market and other conditions. These
            temporary defensive strategies would be inconsistent with the
            investment objective and principal investment strategies of each
            of the Funds and may adversely affect a Fund's ability to achieve
            its investment objective.

Companies
With
Smaller
Market
Capitalizations
            Each of the Funds may invest in securities of companies with
            market capitalizations that are small compared to other publicly
            traded companies. The NFJ Value 25 Fund has significant exposure
            to the risks described below because it invests primarily in
            companies with medium-sized market capitalization, which are
            smaller and generally less well-known or seasoned than the largest
            companies. Companies which are smaller and less well-known or
            seasoned than larger, more widely held companies may offer greater
            opportunities for capital appreciation, but may also involve risks
            different from, or greater than, risks normally associated with
            larger companies. Larger companies generally have greater
            financial resources, more extensive research and development,
            manufacturing, marketing and service capabilities, and more
            stability and greater depth of management and technical personnel
            than smaller companies. Smaller companies may have limited product
            lines, markets or financial resources or may depend on a small,
            inexperienced management group. Securities of

                                                                   Prospectus 20
<PAGE>

            smaller companies may trade less frequently and in lesser volume
            than more widely held securities and their values may fluctuate
            more abruptly or erratically than securities of larger companies.
            They may also trade in the over-the-counter market or on a
            regional exchange, or may otherwise have limited liquidity. These
            securities may therefore be more vulnerable to adverse market
            developments than securities of larger companies. Also, there may
            be less publicly available information about smaller companies or
            less market interest in their securities as compared to larger
            companies, and it may take longer for the prices of the securities
            to reflect the full value of a company's earnings potential or
            assets.

             Because securities of smaller companies may have limited
            liquidity, a Fund may have difficulty establishing or closing out
            its positions in smaller companies at prevailing market prices. As
            a result of owning large positions in this type of security, a
            Fund is subject to the additional risk of possibly having to sell
            portfolio securities at disadvantageous times and prices if
            redemptions require the Fund to liquidate its securities
            positions. For these reasons, it may be prudent for a Fund with a
            relatively large asset size to limit the number of relatively
            small positions it holds in securities having limited liquidity in
            order to minimize its exposure to such risks, to minimize
            transaction costs, and to maximize the benefits of research. As a
            consequence, as a Fund's asset size increases, the Fund may reduce
            its exposure to illiquid smaller capitalization securities, which
            could adversely affect performance.

Intial      The Funds may purchase securities in initial public offerings
Public      (IPOs). These securities are subject to many of the same risks of
Offerings   investing in companies with smaller market capitalizations.
            Securities issued in IPOs have no trading history, and information
            about the companies may be available for very limited periods. In
            addition, the prices of securities sold in IPOs may be highly
            volatile. At any particular time or from time to time, a Fund may
            not be able to invest in securities issued in IPOs, or invest to
            the extent desired, because, for example, only a small portion (if
            any) of the securities being offered in an IPO may be made
            available to the Fund. In addition, under certain market
            conditions a relatively small number of companies may issue
            securities in IPOs. Similarly, as the number of Funds to which IPO
            securities are allocated increases, the number of securities
            issued to any one Fund may decrease. The investment performance of
            a Fund during periods when it is unable to invest significantly or
            at all in IPOs may be lower than during periods when the Fund is
            able to do so. In addition, as a Fund increases in size, the
            impact of IPOs on the Fund's performance will generally decrease.

Foreign
(non-       Each of the Funds may invest in foreign securities, including
U.S.)       American Depository Receipts (ADRs). ADRs are dollar-denominated
Securities  receipts issued generally by domestic banks and representing the
            deposit with the bank of a security of a foreign issuer, and are
            publicly traded on exchanges or over-the-counter in the United
            States.

             Investing in foreign securities involves special risks and
            considerations not typically associated with investing in U.S.
            securities and shareholders should consider carefully the
            substantial risks involved for Funds that invest in these
            securities. 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, rate
            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.

Emerging    Each of the Funds may invest in securities of issuers based in or
Market      that trade principally in countries with developing (or "emerging
Securities  market") economies. 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;
            and possible repatriation of investment income and capital. In
            addition, foreign investors may be required to register the
            proceeds of sales, and future economic or political crises could
            lead to price controls, forced mergers, expropriation or
            confiscatory taxation, seizure, nationalization or the 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 market 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.

             Special Risks of Investing in Russian and Other Eastern European
            Securities. Each of the Funds may invest a portion of its assets
            in securities of issuers located in Russia and in other Eastern
            European countries. While investments in securities of such
            issuers are subject generally to the same risks associated with
            investments in other emerging market countries described above,
            the political, legal and operational risks of investing in Russian
            and other Eastern European issuers, and of having assets custodied
            within these countries, may be particularly acute. A risk of
            particular note with respect to direct investment in Russian
            securities is the way in which ownership of shares of companies is
            normally recorded. When a Fund invests in a Russian issuer, it
            will normally receive a "share extract," but that extract is not
            legally determinative of ownership. The official record of
            ownership of a company's share is maintained by the company's
            share registrar. Such share registrars are completely under the
            control of the issuer, and investors are provided with few legal
            rights against such registrars.



Foreign
Currencies  A Fund that invests directly in foreign currencies or in
            securities that trade in, and receive revenues in, foreign
            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 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, uncertainty surrounds the introduction
            of the euro (a common currency unit for the European Union) and
            the effect it may have on the value of European currencies as well
            as 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.

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

                                                                   Prospectus 22
<PAGE>

            stock at either a stated price or a stated 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. While
            convertible securities generally offer lower interest or dividend
            yields than non-convertible fixed income securities of similar
            quality, their value tends to increase as the market value of the
            underlying stock increases and to decrease when the value of the
            underlying stock decreases. Also, 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.

Credit      The Funds may invest in securities based on their credit ratings
Ratings     assigned by rating agencies such as Moody's Investors Service,
and         Inc. ("Moody's") and Standard & Poor's Ratings Services ("S&P").
Unrated     Moody's, S&P and other rating agencies are private services that
Securities  provide ratings of the credit quality of fixed income securities,
            including convertible securities. The Appendix to the Statement of
            Additional Information 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 risk. 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 Advisors and NFJ
            do not rely solely on credit ratings, and develop their 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.

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 the party arranging the loan.

Short       Each Fund may make short sales as part of its overall portfolio
Sales       management strategies or to offset a potential decline in the
            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. A Fund may only enter into short selling transactions if
            the security sold short is held in the Fund's portfolio or if the
            Fund has the right to acquire the security without the payment of
            further consideration. 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.

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
Transactions settlement date. This risk is in addition to the risk that the
             Fund's other assets will decline in value. Therefore,

23 PIMCO Funds: Multi-Manager Series

            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 that 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, subject to
Repurchase  the Fund's limitations on borrowings. A reverse repurchase
Agreements  agreement involves the sale of a security by a Fund and its
and Other   agreement to repurchase the instrument at a specified time and
Borrowings  price, and may be considered a form of borrowing for some
            purposes. A Fund will segregate assets determined to be liquid by
            PIMCO Advisors or NFJ in accordance with procedures established by
            the Board of Trustees to cover its obligations under reverse
            repurchase agreements. 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 and other forms of borrowings may
            create leveraging risk for a Fund.

Illiquid    Each Fund may invest in securities that are illiquid so long as
Securities  not more than 15% of the value of the Fund's net assets (taken at
            market value at the time of investment) would be invested in such
            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 held by the
            Fund, 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. Please see "Investment Objectives and Policies" in
            the Statement of Additional Information for a listing of various
            securities that are generally considered to be illiquid for these
            purposes. 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 of the Funds may invest up to 5% of its assets in securities
in Other    of other investment companies, such as closed-end management
Investment  investment companies, or in other pooled investment vehicles. As a
Companies   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.

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 active and frequent trading of portfolio
            securities to achieve its investment objective and principal
            investment strategies, 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 taxed
            at ordinary income tax rates when distributed to shareholders who
            are individuals). The trading costs and tax effects associated
            with portfolio turnover may adversely affect a Fund's performance.

                                                                   Prospectus 24

Changes     The investment objective of each Fund may be changed by the Board
in          of Trustees without shareholder approval. Unless otherwise stated
Investment  in the Statement of Additional Information, all investment
Objectives  policies of the Funds may be changed by the Board of Trustees
and         without shareholder approval. If there is a change in a Fund's
Policies    investment objective or policies, including a change approved by
            shareholder vote, shareholders should consider whether the Fund
            remains an appropriate investment in light of their then current
            financial position and needs.

</TABLE>

          The Fund seeks to achieve its investment objective by normally
          investing at least 65% of its assets in common stocks of companies
          with larger market capitalizations that have improving fundamentals
          (based on growth criteria) and whose stock is reasonably valued by the
          market (based on value criteria).

             In making investment decisions for the Fund, the portfolio
          management team considers the 1,000 largest publicly traded companies
          (in terms of market capitalization) in the U.S.  The team screens the
          stocks in this universe for a series of growth criteria, such as
          dividend growth, earnings growth, relative growth of earnings over
          time (earnings momentum) and the company's history of meeting earnings
          targets (earnings surprise), and also value criteria, such as price-
          to-earnings, price-to-book and price-to-cash flow ratios.  The team
          then selects individual stocks by subjecting the top 10% of the stocks
          in the screened universe to a rigorous analysis of company factors,
          such as strength of management, competitive industry position, and
          business prospects, and financial statement data, such as earnings,
          cash flows and profitability.  The team may interview company
          management in making investment decisions.  The Fund's capitalization
          criteria applies at the time of investment.

             The portfolio management team rescreens the universe frequently and
          seeks to consistently achieve a favorable balance of growth and value
          characteristics for the Fund.  The team sells a stock when it falls
          below the median ranking, has negative earnings surprises, or shows
          poor performance relative to all stocks in the Fund's capitalization
          range or to companies in the same business sector.  A stock may also
          be sold if its weighting in the portfolio becomes excessive (normally
          above 2% of the Fund's investments).

             The Fund intends to be fully invested in common stock (aside from
          certain cash management practices) and will not make defensive
          investments in response to unfavorable market and other conditions.

Examples.  The Examples below are intended to help you compare the cost of
investing in Institutional Class or Administrative Class 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 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 at least 65% of its assets in common stocks of companies
          with medium market capitalizations that have improving fundamentals
          (based on growth criteria) and whose stock is reasonably valued by the
          market (based on value criteria).

             In making investment decisions for the Fund, the portfolio
          management team considers companies in the U.S. with market
          capitalizations of more than $500 million, but excluding the 200
          largest capitalization companies. The team screens the stocks in this
          universe for a series of growth criteria, such as dividend growth,
          earnings growth, relative growth of earnings over time (earnings
          momentum) and the company's history of meeting earnings targets
          (earnings surprise), and also value criteria, such as price-to-
          earnings, price-to-book and price-to-cash flow ratios. The team then
          selects individual stocks by subjecting the top 10% of the stocks in
          the screened universe to a rigorous analysis of company factors, such
          as strength of management, competitive industry position, and business
          prospects, and financial statement data, such as earnings, cash flows
          and profitability. The team may interview company management in making
          investment decisions. The Fund's capitalization criteria applies at
          the time of investment.

             The portfolio management team rescreens the universe frequently and
          seeks to consistently achieve a favorable balance of growth and value
          characteristics for the Fund. The team sells a stock when it falls
          below the median ranking, has negative earnings surprises, or shows
          poor price performance relative to all stocks in the Fund's
          capitalization range or to companies in the same business sector. A
          stock may also be sold if its weighting in the portfolio becomes
          excessive (normally above 2% of the Fund's investments).

             The Fund intends to be fully invested in common stock (aside from
          certain cash management practices) and will not make defensive
          investments in response to unfavorable market and other conditions.

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 summarized 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 each 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.


Market Risk

The market price of securities owned by a Fund may go up or down, sometimes
rapidly or unpredictably. Each of the Funds normally invests most of its assets
in common stocks and/or other equity securities. A principal risk of investing
in each Fund is that the equity securities in its portfolio will decline in
value due to factors affecting equity securities markets generally or particular
industries represented in those markets. The values of equity securities 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 Risk

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

Value Securities Risk

The Funds place particular emphasis on investing in securities of companies that
may not be expected to experience significant earnings growth, but whose
securities its portfolio manager believes are selling at a price lower than
their true value (value securities). Companies that issue value securities may
have experienced adverse business developments or may be subject to special
risks that have caused their securities to be out of favor. If a portfolio
manager's assessment of a company's prospects is wrong, or if the market does
not recognize the value of the company, the price of its securities may decline
or may not approach the value that the portfolio manager anticipates.

Growth Securities Risk

The Funds place particular emphasis on investing in equity securities of
companies that its portfolio manager believes will experience relatively rapid
earnings growth (growth securities).  Growth securities typically trade at
higher multiples of current earnings than other securities. Therefore, the
values of growth securities may be more sensitive to changes in current or
expected earnings than the values of other securities.
<PAGE>

Smaller Company Risk

The general risks associated with equity securities and liquidity risk are
particularly pronounced for securities of companies with smaller market
capitalizations. These companies may have limited product lines, markets or
financial resources or they may depend on a few key employees. Securities of
smaller companies may trade less frequently and in lesser volume than more
widely held securities and their values may fluctuate more sharply than other
securities. They may also trade in the over-the-counter market or on a regional
exchange, or may otherwise have limited liquidity. The Cadence Mid-Cap Growth
Fund has significant exposure to this risk because it invests substantial assets
in companies with medium-sized market capitalizations, which are smaller and
generally less well-known or seasoned than the largest companies.

Liquidity Risk

Each of the Funds are subject to liquidity risk. Liquidity risk exists when
particular investments are difficult to purchase or sell, possibly preventing a
Fund from selling such illiquid securities at an advantageous time or price.
Funds with principal investment strategies that involve securities of companies
with smaller market capitalizations or securities with substantial market and/or
credit risk tend to have the greatest exposure to liquidity risk.

Credit Risk

Each of the Funds are subject to credit risk. This is the risk that the issuer
or the guarantor of a fixed income security, or the counterparty to a 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 their credit ratings.

Management Risk

Each Fund is subject to management risk because it is an actively managed
investment portfolio. PIMCO Advisors, Cadence 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.

Management of the Funds

Investment Adviser and Administrator

PIMCO Advisors serves as the investment adviser and the administrator (serving
in its capacity as administrator, the "Administrator") for the Funds. Subject to
the supervision of the Board of Trustees, PIMCO Advisors is responsible for
managing, either directly or through others selected by it, the investment
activities of the Funds and the Funds' business affairs and other administrative
matters.

  PIMCO Advisors is located at 800 Newport Center Drive, Newport Beach,
California 92660. Organized in 1987, PIMCO Advisors provides investment
management and advisory services to private accounts of institutional and
individual clients and to mutual funds. As of September 30, 2000, PIMCO Advisors
and its subsidiary partnerships had approximately $272 billion in assets under
management.

  PIMCO Advisors has retained an affiliated investment management firm, Cadence
Capital Management ("Cadence " or the "Sub-Adviser") to manage each Fund's
investments. See "Sub-Adviser" below. PIMCO Advisors has retained its affiliate,
Pacific Investment Management Company LLC, to provide various administrative
and other services required by the Funds in its capacity as sub-administrator.
PIMCO Advisors and the sub-administrator may retain other affiliates to provide
certain of these services.

<PAGE>
Advisory Fees

  Each Fund pays PIMCO Advisors fees in return for providing or arranging for
the provision of investment advisory services. PIMCO Advisors (and not the
Funds) pays a portion of the advisory fees it receives to Cadence in return for
Cadence's services as Sub-Advisor.

  The Funds pay monthly advisory fees to PIMCO Advisors at the following annual
rates (stated as a percentage of the average daily net assets of each Fund taken
separately):

Administrative Fees


            Each Fund pays for the administrative services it requires under a
            fee structure which is essentially fixed. Institutional and
            Administrative Class shareholders of each Fund pay an
            administrative fee to PIMCO Advisors, computed as a percentage of
            the Fund's assets attributable in the aggregate to those classes
            of shares. PIMCO Advisors, in turn, provides or procures
            administrative services for Institutional and Administrative Class
            shareholders and also bears the costs of most 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 that Institutional and Administrative
            Class shareholders of each Fund bear expenses for administrative
            services at a level that is precise and predictable under ordinary
            circumstances. The Funds do bear other expenses which are not
            covered under the administrative fee which may vary and effect the
            total level of expenses paid by Institutional and Administrative
            Class shareholders, such as brokerage fees, commissions and other
            transaction expenses, costs of borrowing money, including interest
            expenses, and fees and expenses of the trust's disinterested
            trustees.

  Institutional and Administrative Class shareholders of the Funds pay PIMCO
Advisors monthly administrative fees at the annual rate of 0.25% (stated as a
percentage of the average daily net assets attributable in the aggregate to the
Fund's Institutional and Administrative Class shares).

Adviser/Sub-Adviser Relationship

Shareholders of each Fund have approved a proposal permitting PIMCO Advisors to
enter into new or amended sub-advisory agreements with one or more sub-advisers
with respect to each Fund without obtaining shareholder approval of such
agreements, subject to the conditions of an exemptive order that has been
granted by the Securities Exchange Commission. One of the conditions requires
the Board of Trustees to approve any such agreement. In addition, the exemptive
order prohibits PIMCO Advisors from entering into sub-advisory agreements with
affiliates of PIMCO Advisors without shareholder approval, unless those
affiliates are substantially wholly-owned by PIMCO Advisors. PIMCO ADVISORS HAS
THE ULTIMATE RESPONSIBLITY TO OVERSEE THE SUB-ADVISERS AND TO RECOMMEND THEIR
HIRING, TERMINATION AND REPLACEMENT.

Distributor

The Trust's Distributor is PIMCO Funds Distributors LLC, 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

Investment Options --
Institutional Class and Administrative Class Shares

The Trust offers investors Institutional Class and Administrative Class shares
of the Funds in this Prospectus.

     The Trust does not charge any sales charges (loads) or other fees in
connection with purchases, sales (redemptions) or exchanges of Institutional
Class or Administrative Class shares. See "Purchases, Redemptions and Exchanges"
below.

     Administrative Class shares are generally subject to a higher level of
operating expenses than Institutional Class shares due to the additional service
and/or distribution fees paid by Administrative Class shares as described below.
Therefore, Institutional Class shares will generally pay higher dividends and
have a more favorable investment return than Administrative Class shares.

 .  Service and Distribution (12b-1) Fees--Administrative Class Shares. The Trust
has adopted both an Administrative Services Plan and a Distribution Plan for the
Administrative Class shares of each Fund. Each Plan has been adopted in
accordance with the requirements of Rule 12b-1 under the Investment Company Act
of 1940 and is administered in accordance with that rule. However, shareholders
do not have the voting rights set forth in Rule 12b-1 with respect to the
Administrative Services Plan.

     Each Plan allows the Funds to use its Administrative Class assets to
reimburse financial intermediaries that provide services relating to
Administrative Class shares. The Distribution Plan permits reimbursement for
expenses in connection with the distribution and marketing of Administrative
Class shares and/or the provision of shareholder services to Administrative
Class shareholders. The Administrative Services Plan permits reimbursement for
services in connection with the administration of plans or programs that use
Administrative Class shares of the Funds as their funding medium and for related
expenses.

     In combination, the Plans permit a Fund to make total reimbursements at an
annual rate of up to 0.25% of the Fund's average daily net assets attributable
to its Administrative Class shares. The same entity may not receive both
distribution and administrative services fees with respect to the same
Administrative Class assets, but may receive fees under each Plan with respect
to separate assets. Because these fees are paid out of a Fund's Administrative
Class assets on an ongoing basis, over time they will increase the cost of an
investment in Administrative Class shares and may cost an investor more than
other types of sales charges.

 .  Arrangements with Service Agents. Institutional Class and Administrative
Class shares of the Funds may 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 and/or distribution fees paid
with respect to Administrative Class shares. Service agents may impose
additional or different conditions than the Trust on purchases, redemptions or
exchanges of Fund shares by their customers. Service agents may also
independently establish and charge their customers transaction fees, account
fees and other amounts in connection with purchases, sales and redemptions of
Fund shares in addition to any fees charged by the Trust. These additional fees
may vary over time and would increase the cost of the customer's investment and
lower investment returns. 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, redemptions and
exchanges. Shareholders who are customers of service agents should consult their
service agents for information regarding these fees and conditions.

Purchases, Redemptions and Exchanges
<PAGE>

 .  Purchasing Shares. Investors may purchase Institutional Class and
Administrative Class shares of the Funds at the relevant net asset value
("NAV") of that class without a sales charge or other fee.

     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 their customers' investments in the Funds.

     Administrative Class shares are offered primarily through employee benefit
plan alliances, broker-dealers and other intermediaries, and each Fund pays
service and/or distribution fees to these entities for services they provide to
Administrative Class shareholders.

     Pension and profit-sharing plans, employee benefit trusts and employee
benefit plan alliances and "wrap account" programs established with broker-
dealers or financial intermediaries may purchase shares of either class only if
the plan or program for which the shares are being acquired will maintain an
omnibus or pooled account for each Fund and will not require a Fund to pay any
type of administrative payment per participant account to any third party.

 .  Investment Minimums. The minimum initial investment for shares of either
class is $5 million, except that the minimum initial investment for a registered
investment adviser purchasing Institutional Class shares for its clients through
omnibus accounts is $250,000 per Fund. The minimum initial investment may be
waived for Institutional or Administrative Class shares offered to clients of
Cadence and its affiliates. In addition, the minimum initial investment does not
apply to Institutional Class shares offered through fee-based programs sponsored
and maintained by a registered broker-dealer and approved by the Distributor in
which each investor pays an asset based fee at an annual rate of at least 0.50%
of the assets in the account to a financial intermediary for investment advisory
and/or administrative services.

     The Trust and the Distributor may waive the minimum initial investment for
other categories of investors at their discretion.

 .  Timing of Purchase Orders and Share Price Calculations. A purchase order
received by the Trust's transfer agent, National Financial Data Services (the
"Transfer Agent") prior to the close of regular trading (normally 4:00 p.m.,
Eastern time) on the New York Stock Exchange, on a day the Trust is open for
business, together with payment made in one of the ways described below, will be
effected at that day's net asset value ("NAV"). An order received after the
close of regular trading on the New York Stock Exchange will be effected at the
NAV determined on the next business day. However, orders received by certain
retirement plans and other financial intermediaries on a business day prior to
the close of regular trading on the New York Stock Exchange and communicated to
the Transfer Agent prior to 9:00 a.m., Eastern time, on the following business
day will be effected at the NAV determined on the prior business day. The Trust
is "open for business" on each day the New York Stock Exchange is open for
trading, which excludes the following holidays: New Year's Day, Martin Luther
King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day,
Labor Day, Thanksgiving Day and Christmas Day. Purchase orders will be accepted
only on days on which the Trust is open for business.

 .  Initial Investment. Investors may open an account by completing and signing a
Client Registration Application and mailing it to PIMCO Funds at 840 Newport
Center Drive, Suite 300, Newport Beach, California 92660. A Client Registration
Application may be obtained by calling 1-800-927-4648.

     Except as described below, an investor may purchase Institutional Class and
Administrative Class shares only by wiring federal funds to the Transfer Agent,
National Financial Data Services, 330 West 9th Street, 4th Floor, Kansas City,
Missouri 64105. Before wiring federal funds, the investor must telephone the
Trust at 1-800-927-4648 to receive instructions for wire transfer and must
provide the following information: name of authorized person, shareholder name,
shareholder account number, name of Fund and share class, amount being wired,
and wiring bank name.
<PAGE>

    An investor may purchase shares without first wiring federal funds if the
proceeds of the investment are derived from an advisory account the investor
maintains with PIMCO Advisors or one of its affiliates, from surrender or other
payment from an annuity, insurance, or other contract held by Pacific Life
Insurance Company LLC, or from an investment by broker-dealers, institutional
clients or other financial intermediaries which have established a shareholder
servicing relationship with the Trust on behalf of their customers.

 .  Additional Investments. An investor may purchase additional Institutional
Class and Administrative Class shares of the Funds at any time by calling the
Trust and wiring federal funds to the Transfer Agent as outlined above.

 .  Other Purchase Information. Purchases of a Fund's Institutional Class and
Administrative Class shares will be made in full and fractional shares. In the
interest of economy and convenience, certificates for shares will not be issued.

     The Trust and the Distributor each reserves the right, in its sole
discretion, to suspend the offering of shares of the Funds or to reject any
purchase order, in whole or in part, when, in the judgment of management, such
suspension or rejection is in the best interests of the Trust.

     An investor should invest in the Funds for long-term investment purposes
only.  The Trust, PIMCO Advisors and Cadence each reserve the right to restrict
purchases of Fund shares (including exchanges) when a pattern of frequent
purchases and sales made in response to short-term fluctuations in share price
appears evident. Notice of any such restrictions, if any, will vary according to
the particular circumstances.

     Institutional Class and Administrative Class shares of the Trust are not
qualified or registered for sale in all states. Investors should inquire as to
whether shares of a particular Fund are available for offer and sale in the
investor's state of residence. Shares of the Trust may not be offered or sold in
any state unless registered or qualified in that jurisdiction or unless an
exemption from registration or qualification is available.

     Subject to the approval of the Trust, an investor may purchase shares of a
Fund with liquid securities that are eligible for purchase by the Fund
(consistent with the Fund's investment policies and restrictions) and that have
a value that is readily ascertainable in accordance with the Trust's valuation
policies. These transactions will be effected only if PIMCO Advisors or Cadence
intends to retain the security in the Fund as an investment. Assets purchased by
a Fund in such a transaction will be valued in generally the same manner as they
would be valued for purposes of pricing the Fund's shares, if such assets were
included in the Fund's assets at the time of purchase. The Trust reserves the
right to amend or terminate this practice at any time.

 .  Retirement Plans. Shares of the Funds are available for purchase by
retirement and savings plans, including Keogh plans, 401(k) plans, 403(b)
custodial accounts, and Individual Retirement Accounts. The administrator of a
plan or employee benefits office can provide participants or employees with
detailed information on how to participate in the plan and how to elect a Fund
as an investment option. Participants in a retirement or savings plan may be
permitted to elect different investment options, alter the amounts contributed
to the plan, or change how contributions are allocated among investment options
in accordance with the plan's specific provisions. The plan administrator or
employee benefits office should be consulted for details. For questions about
participant accounts, participants should contact their employee benefits
office, the plan administrator, or the organization that provides recordkeeping
services for the plan. Investors who purchase shares through retirement plans
should be aware that plan administrators may aggregate purchase and redemption
orders for participants in the plan. Therefore, there may be a delay between the
time the investor places an order with the plan administrator and the time the
order is forwarded to the Transfer Agent for execution.

Redeeming Shares

 .  Redemptions by Mail. An investor may redeem (sell) Institutional Class and
Administrative Class shares by submitting a written request to PIMCO Funds at
840 Newport Center Drive, Suite 300, Newport Beach, California 92660. The
redemption request should state the Fund from which the shares are to be
redeemed, the class
<PAGE>

of shares, the number or dollar amount of the shares to be redeemed and the
account number. The request must be signed exactly as the names of the
registered owners appear on the Trust's account records, and the request must be
signed by the minimum number of persons designated on the Client Registration
Application that are required to effect a redemption.

     Redemptions by Telephone or Other Wire Communication. An investor that
elects this option on the Client Registration Application (or subsequently in
writing) may request redemptions of shares by calling the Trust at 1-800-927-
4648, by sending a facsimile to 1-949-725-6830, or by other means of wire
communication (excluding electronic mail). Investors should state the Fund and
class from which the shares are to be redeemed, the number or dollar amount of
the shares to be redeemed, the account number and the signature of an authorized
signatory. Redemption requests of an amount of $10 million or more may be
initiated by telephone, but must be confirmed in writing by an authorized party
prior to processing.

     In electing a telephone redemption, the investor authorizes Pacific
Investment Management Company LLC and the Transfer Agent to act on telephone
instructions from any person representing himself to be the investor, and
reasonably believed by Pacific Investment Management Company LLC or the Transfer
Agent to be genuine. Neither the Trust nor the Transfer Agent may be liable for
any loss, cost or expense for acting on instructions (whether in writing or by
telephone) believed by the party receiving such instructions to be genuine and
in accordance with the procedures described in this Prospectus. Shareholders
should realize that by electing the telephone or wire redemption option, they
may be giving up a measure of security that they might have if they were to
redeem their shares in writing. Furthermore, interruptions in telephone service
may mean that a shareholder will be unable to effect a redemption by telephone
when desired. The Transfer Agent also provides written confirmation of
transactions initiated by telephone as a procedure designed to confirm that
telephone instructions are genuine (written confirmation is also provided for
redemption requests received in writing). All telephone transactions are
recorded, and Pacific Investment Management Company LLC or the Transfer Agent
may request certain information in order to verify that the person giving
instructions is authorized to do so. The Trust or Transfer Agent may be liable
for any losses due to unauthorized or fraudulent telephone transactions if it
fails to employ reasonable procedures to confirm that instructions communicated
by telephone are genuine. All redemptions, whether initiated by letter or
telephone, will be processed in a timely manner, and proceeds will be forwarded
by wire in accordance with the redemption policies of the Trust detailed below.
See "Other Redemption Information."

     Shareholders may decline telephone exchange or redemption privileges after
an account is opened by instructing the Transfer Agent in writing at least seven
business days prior to the date the instruction is to be effective. Shareholders
may experience delays in exercising telephone redemption privileges during
periods of abnormal market activity. During periods of volatile economic or
market conditions, shareholders may wish to consider transmitting redemption
orders by telegram, facsimile or overnight courier.

     Defined contribution plan participants may request redemptions by
contacting the employee benefits office, the plan administrator or the
organization that provides recordkeeping services for the plan.

     Other Redemption Information. Redemption requests for Fund shares are
effected at the NAV per share next determined after receipt of a redemption
request by the Trust or its designee. The request must properly identify all
relevant information, such as account number, redemption amount (in dollars or
shares) and the Fund name, and must be executed or initialed by the appropriate
signatories. A redemption request received by the Trust or its designee prior to
the close of regular trading on the New York Stock Exchange (normally 4:00 p.m.,
Eastern time), on a day the Trust is open for business, is effective on that
day. A redemption request received after that time becomes effective on the next
business day.

     Redemption proceeds will ordinarily be wired to the investor's bank within
three business days after the redemption request, but may take up to seven
business days. Redemption proceeds will be sent by wire only to the bank name
designated on the Client Registration Application. The Trust may suspend the
right of redemption or postpone the payment date at times when the New York
Stock Exchange is closed, or during certain other periods as permitted under the
federal securities laws.
<PAGE>

     For shareholder protection, a request to change information contained in an
account registration (for example, a request to change the bank designated to
receive wire redemption proceeds) must be received in writing, signed by the
minimum number of persons designated on the Client Registration Application that
are required to effect a redemption, and accompanied by a signature guarantee
from any eligible guarantor institution, as determined in accordance with the
Trust's procedures. Shareholders should inquire as to whether a particular
institution is an eligible guarantor institution. A signature guarantee cannot
be provided by a notary public. In addition, corporations, trusts, and other
institutional organizations are required to furnish evidence of the authority of
the persons designated on the Client Registration Application to effect
transactions for the organization.

     Due to the relatively high cost of maintaining small accounts, the Trust
reserves the right to redeem Institutional Class and Administrative Class shares
in any account for their then-current value (which will be promptly paid to the
investor) if at any time, due to redemption by the investor, the shares in the
account do not have a value of at least $100,000. A shareholder will receive
advance notice of a mandatory redemption and will be given at least 30 days to
bring the value of its account up to at least $100,000.

     The Trust agrees to redeem shares of each Fund solely in cash 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 reserves the right to 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 shares would ever be redeemed in
kind. When shares are redeemed in kind, the redeeming shareholder should expect
to incur transaction costs upon the disposition of the securities received in
the distribution.

Exchange Privilege

An investor may exchange Institutional Class or Administrative Class shares of a
Fund for shares of the same class of any other Fund or other series of the Trust
that offers that class based on the respective NAVs of the shares involved. An
exchange may be made by following the redemption procedure described above under
"Redemptions by Mail" or, if the investor has elected the telephone redemption
option, by calling the Trust at 1-800-927-4648. An investor may also exchange
shares of a Fund for shares of the same class of a series of PIMCO Funds:
Pacific Investment Management Series, an affiliated mutual fund family composed
primarily of fixed income portfolios managed by Pacific Investment Management
Company [LLC]. Shareholders interested in such an exchange may request a
prospectus for these other series by contacting PIMCO Funds: Pacific Investment
Management Series at the same address and telephone number as the Trust.

     An investor may exchange shares only with respect to Funds or other
eligible series that are registered in the investor's state of residence or
where an exemption from registration is available. In addition, an exchange is
generally a taxable event which will generate capital gains or losses, and
special rules may apply in computing tax basis when determining gain or loss.
See "Tax Consequences" in this Prospectus and "Taxation" in the Statement of
Additional Information.

     The Trust reserves the right to refuse exchange purchases if, in the
judgment of PIMCO Advisors, 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 Advisors to be detrimental to the
Trust or a particular Fund. Currently, the Trust limits the number of "round
trip" exchanges investors 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 PIMCO 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. The Trust reserves the right to impose additional restrictions on
exchanges at any time, although it will attempt to give shareholders 30 days'
prior notice whenever it is reasonably able to do so.
<PAGE>

How Fund Shares Are Priced

     The net asset value ("NAV") of a Fund's Institutional and Administrative
Class 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 the 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 quotes are not readily available may be
valued, pursuant to procedures established by the Board of Trustees, with
reference to other securities or 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 their 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 or persons acting at their
direction, generally based upon recommendations provided by PIMCO Advisors
and/or Cadence. Fair valuation may also be used by the Board of Trustees if
extraordinary events occur after the close of the relevant market but prior to
the NYSE Close.

     Under certain circumstances, the per share NAV of the Administrative Class
shares of the Funds may be lower than the per share NAV of the Institutional
Class shares as a result of the daily expense accruals of the service and/or
distribution fees paid by Administrative Class 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 the two
classes.


Fund Distributions

Each Fund distributes substantially all of its net investment income to
shareholders in the form of dividends. A shareholder begins earning dividends on
Fund shares the day after the Trust receives the shareholder's 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, but dividends on Administrative Class
shares are expected to be lower than dividends on Institutional Class shares as
a result of the service and/or distribution fees applicable to Administrative
Class shares.
<PAGE>

     Each Fund intends to declare and distribute income dividends to
shareholders of record at least annually. 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 pa id more
frequently.

     A Fund's dividend and capital gain distributions with respect to a
particular class of shares will automatically be reinvested in additional shares
of the same class of the Fund at NAV unless the shareholder elects to have the
distributions paid in cash. A shareholder may elect to have distributions paid
in cash by calling the Trust at 1-800-927-4648.

     Shareholders do not pay any sales charges or other fees on shares received
through the reinvestment of Fund distributions.

     For further information on distribution options, please contact the Trust
at 1-800-927-4648.


Tax Consequences

 .  Taxes on Fund Distributions. A shareholder subject to U.S. federal income tax
will be subject to tax on Fund distributions whether they are paid in cash or
reinvested in additional shares of the Funds. For federal income tax purposes,
Fund distributions will be taxable to the shareholder as either ordinary income
or capital gains.

     Fund dividends (i.e., distributions of investment income) are taxable to
shareholders 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 the shareholder owned the shares. Distributions of
gains from investments that a Fund owned for more than 12 months will generally
be taxable to shareholders as capital gains. Distributions of gains from
investments that the Fund owned for 12 months or less will generally be taxable
as ordinary income.

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

 .  Taxes on Redemptions or Exchanges of Shares. Any gain resulting from the sale
of Fund shares will generally be subject to federal income tax. When a
shareholder exchanges shares of a Fund for shares of another series, the
transaction generally 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.

 .  A Note on Foreign Investments. A Fund's investment in foreign securities may
be subject to foreign withholding taxes. In that case, the Fund's yield on those
securities would be decreased. In addition, a Fund's investments in foreign
securities or foreign currencies may increase or accelerate the Fund's
recognition of ordinary income and may affect the timing or amount of the Fund's
distributions.

 .    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 local income tax laws to Fund
dividends and capital distributions. Please see the Statement of Additional
Information for additional information regarding the tax aspects of investing in
the Funds.

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 identified under "Summary
Information" above. It also describes characteristics and risks of additional
securities and investment techniques that are not necessarily principal
investments or strategies but may be used by the Funds from time to time. Most
of these securities and investment techniques are discretionary, which means
that the portfolio managers 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 must rely on the professional investment judgment
and skill of the Funds' Adviser and Sub-Adviser 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.

Fixed Income Securities and Defensive Strategies

Fixed income securities are obligations of the issuer to make payments of
principal and/or interest on future dates, and include corporate and government
bonds, notes, certificates of deposit, commercial paper, convertible securities
and mortgage-backed and other asset-backed securities.

     Aside from the cash management practices described below, the Funds intend
to be as fully invested in common stocks as practicable at all times. For cash
management purposes, each of the Funds may maintain a portion of its assets
(normally not more than 10%) in U.S. Government securities, high quality fixed
income securities, money market obligations and cash to pay certain Fund
expenses and to meet redemption requests. Neither of the Funds will make
defensive investments in response to unfavorable market and other conditions and
therefore may be particularly vulnerable to general declines in stock prices
and/or other categories of securities in which they invest.
<PAGE>

Companies With Smaller Market Capitalizations

Each of the Funds may invest in securities of companies with market
capitalizations that are small compared to other publicly traded companies. The
Cadence Mid-Cap Growth Fund has significant exposure to these risks because it
invests primarily in companies with medium-sized market capitalizations, which
are smaller and generally less well-known or seasoned than the largest
companies.

     Companies which are smaller and less well-known or seasoned than larger,
more widely held companies may offer greater opportunities for capital
appreciation, but may also involve risks different from, or greater than, risks
normally associated with larger companies. Larger companies generally have
greater financial resources, more extensive research and development,
manufacturing, marketing and service capabilities, and more stability and
greater depth of management and technical personnel than smaller companies.
Smaller companies may have limited product lines, markets or financial resources
or may depend on a small, inexperienced management group. Securities of smaller
companies may trade less frequently and in lesser volume than more widely held
securities and their values may fluctuate more abruptly or erratically than
securities of larger companies. They may also trade in the over-the-counter
market or on a regional exchange, or may otherwise have limited liquidity. These
securities may therefore be more vulnerable to adverse market developments than
securities of larger companies. Also, there may be less publicly available
information about smaller companies or less market interest in their securities
as compared to larger companies, and it may take longer for the prices of the
securities to reflect the full value of a company's earnings potential or
assets.

     Because securities of smaller companies may have limited liquidity, a Fund
may have difficulty establishing or closing out its positions in smaller
companies at prevailing market prices. As a result of owning large positions in
this type of security, a Fund is subject to the additional risk of possibly
having to sell portfolio securities at disadvantageous times and prices if
redemptions require the Fund to liquidate its securities positions. For these
reasons, it may be prudent for a Fund with a relatively large asset size to
limit the number of relatively small positions it holds in securities having
limited liquidity in order to minimize its exposure to such risks, to minimize
transaction costs, and to maximize the benefits of research. As a consequence,
as a Fund's asset size increases, the Fund may reduce its exposure to illiquid
smaller capitalization securities, which could adversely affect performance.

Foreign (non-U.S.) Securities

All of the Funds may invest in foreign securities, including American Depository
Receipts ("ADRs"). ADRs are dollar-denominated receipts issued generally by
domestic banks and representing the deposit with the bank of a security of a
foreign issuer, and are publicly traded on exchanges or over-the-counter in the
United States.

     Investing in foreign securities involves special risks and considerations
not typically associated with investing in U.S. securities and shareholders
should consider carefully the substantial risks involved for Funds that invest
in these securities. 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, rate 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.

<PAGE>
Emerging Market Securities

Each of the Funds that may invest in foreign securities may invest in securities
of issuers based in or that trade principally in countries with developing (or
"emerging market") economies. 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;
and possible repatriation of investment income and capital. In addition, foreign
investors may be required to register the proceeds of sales, and future economic
or political crises could lead to price controls, forced mergers, expropriation
or confiscatory taxation, seizure, nationalization or the 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 market 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.

Foreign Currencies

A Fund that invests directly in foreign currencies or in securities that trade
in, and receive revenues in, foreign 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 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.

Convertible Securities

Each Fund may invest in convertible securities. Convertible securities are
generally preferred stocks and other securities, including fixed income
securities and warrants, that are convertible into or exercisable for common
stock at either a stated price or a stated 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. While convertible securities
generally offer lower interest or dividend yields than non-convertible fixed
income securities of similar quality, their value tends to increase as the
market value of the underlying stock increases and to decrease when the value of
the underlying stock decreases. Also, 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.
<PAGE>

Credit Ratings and Unrated Securities

The Funds may invest in securities based on their credit ratings assigned by
rating agencies such as Moody's Investors Service, Inc. ("Moody's") and Standard
& Poor's Ratings Services ("S&P"). Moody's, S&P and other rating agencies are
private services that provide ratings of the credit quality of fixed income
securities, including convertible securities. The Appendix to the Statement of
Additional Information 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 risk. 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 Advisors and Cadence do not rely solely on
credit ratings, and develop their 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.

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 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 the party arranging
the loan.

Short Sales

Each Fund may make short sales as part of its overall portfolio management
strategies or to offset a potential decline in the 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. A Fund may only enter into short selling
transactions if the security sold short is held in the Fund's portfolio or if
the Fund has the right to acquire the security without the payment of further
consideration. 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.

When-Issued, Delayed Delivery and Forward Commitment Transactions

Each Fund may purchase securities which it is eligible to purchase on a when-
issued basis, may purchase and sell such securities for delayed delivery and may
make contracts to purchase such securities for a fixed price at a future date
beyond normal settlement time (forward commitments). When-issued transactions,
delayed delivery purchases and forward commitments involve a risk of loss if the
value of the securities declines prior to the settlement date. This risk is in
addition to the risk that the 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.
<PAGE>

Repurchase Agreements

Each Fund may enter into repurchase agreements, in which the Fund purchases a
security from a bank or broker-dealer that 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. The
Funds will invest in repurchase agreements only as a cash management technique
with respect to that portion of its portfolio maintained in cash. Repurchase
agreements maturing in more than seven days are considered illiquid securities.

Reverse Repurchase Agreements and Other Borrowings

Each Fund may enter into reverse repurchase agreements, subject to the Fund's
limitations on borrowings. A reverse repurchase agreement involves the sale of a
security by a Fund and its agreement to repurchase the instrument at a specified
time and price, and may be considered a form of borrowing for some purposes. A
Fund will segregate assets determined to be liquid by PIMCO Advisors or Cadence
in accordance with procedures established by the Board of Trustees to cover its
obligations under reverse repurchase agreements. 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 and other forms of borrowings may create leveraging risk
for a Fund.

Portfolio Turnover

The length of time a Fund has held a particular security is not 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 active and frequent
trading of portfolio securities to achieve its investment objective and
principal investment strategies, 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 taxed at ordinary income tax rates
when distributed to shareholders who are individuals). The trading costs and tax
effects associated with portfolio turnover may adversely affect a Fund's
performance.

Illiquid Securities

Each Fund may invest in securities that are illiquid so long as not more than
15% of the value of the Fund's net assets (taken at market value at the time of
investment) would be invested in such 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 held by the Fund, 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. Please
see "Investment Objectives and Policies" in the Statement of Additional
Information for a listing of various securities that are generally considered to
be illiquid for these purposes. 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.
<PAGE>

Investment in Other Investment Companies

Each of the Funds may invest up to 5% of its assets in securities of other
investment companies, such as closed-end management investment companies, or in
other pooled investment vehicles. 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.

Changes in Investment Objectives and Policies

The investment objective of each Fund may be changed by the Board of Trustees
without shareholder approval. Unless otherwise stated, all other investment
policies of the Funds may be changed by the Board of Trustees without
shareholder approval. If there is a change in a Fund's investment objective or
policies, including a change approved by shareholder vote, shareholders should
consider whether the Fund remains an appropriate investment in light of their
then current financial position and needs.

Percentage Investment Limitations

Unless otherwise stated, all percentage limitations on Fund investments listed
in this Prospectus will apply at the time of investment. A Fund would not
violate these limitations unless an excess or deficiency occurs or exists
immediately after and as a result of an investment.

Other Investments and Techniques

The Funds may invest in other types of securities and use a variety of
investment techniques and strategies which are not described in this Prospectus.
These securities and techniques may subject the Funds to additional risks.
Please see the Statement of Additional Information for additional information
about the securities and investment techniques described in this Prospectus and
about additional securities and techniques that may be used by the Funds.

         The Fund seeks to achieve its investment objective by normally
investing at least 65% of its assets in common stocks of companies principally
engaged in the design, manufacture or sale of new, creative or different, or
"innovative," products or services used for or in connection with healthcare or
medicine. These companies may (but are not required to) include, for example,
pharmaceutical companies, companies involved in biotechnology, medical
diagnostic, biochemical or other healthcare research and development, companies
involved in the operation of healthcare facilities, and other companies involved
in the design, manufacture or sale of healthcare-related products or services
such as medical, dental and optical products, hardware or services. Except as
indicated above, the Fund is not required to invest exclusively in a particular
business sector or industry.

         The portfolio manager selects stocks for the Fund using a "growth"
style. The portfolio manager seeks to identify health care-related companies
with well-defined "wealth creating" characteristics, including superior earnings
growth (relative to companies in the same industry or the market as a whole),
high profitability and consistent, predictable earnings. In addition, through
fundamental research, the portfolio manager seeks to identify companies that are
gaining market share, have superior management and possess a sustainable
competitive advantage, such as superior or innovative products, personnel and
distribution systems. The Fund looks to sell a stock when the portfolio manager
believes that earnings or market sentiment are disappointing, if the company
does not meet or exceed consensus estimates on revenues and/or earnings or if an
alternative investment is more attractive.

         Although the Fund invests principally in common stocks, the Fund may
also invest in other types of equity securities, including preferred stocks and
convertible securities. The Fund may invest to a significant degree in the
securities of smaller-capitalization companies and in securities issued in
initial public offerings ("IPOs"). The Fund may invest up to 15% of its assets
in foreign securities except that it may invest without limit in American
Depository Receipts.

         In response to unfavorable market and other conditions, the Fund may
make temporary investments of some or all of its assets in high-quality fixed
income securities. This would be inconsistent with the Fund's investment
objective and principal strategies.

Principal Risks  Among the principal risks of investing in the
                 Fund, which could adversely affect its net asset value,

                     (2)      Net Expenses reflect the effect of a contractual
                          agreement by PIMCO Advisors to waive, reduce or

                          Organizational Expenses attributed to the class.
                          Because the Organizational Expenses will all be
                          accounted for in the Fund's initial fiscal year, the
                          Fund's reasonable expectation is that the relevant
                          conditions will not continue after the Fund's fiscal
                          year ending June 30, 2001.

                     Examples. The Examples below are intended to help you
                     compare the cost of investing in Institutional Class or
                     Administrative Class 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 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.(1)

         The Fund seeks to achieve its investment objective by normally
investing at least 65% of its assets in common stocks of companies that derive
at least 50% of their revenues, expenses or profits from the research, design,
development, manufacturing or distribution of new, creative or different, or
"innovative," products, processes or services for use with Internet- or
Internet-related businesses. Some examples of these companies may (but are not
required to) include, for example, providers of broad-band Internet access, web
site content, Internet software and electronic commerce. Except as indicated
above, the Fund is not required to invest exclusively in a particular business
sector or industry.

         The portfolio manager selects stocks for the Fund using a "growth"

         The Fund seeks to achieve its investment objective by normally
investing at least 65% of its assets in common stocks of technology and
technology-related companies with market capitalizations of between $100 million
and $2 billion at the time of investment. The Fund identifies its investment
universe of technology-related companies primarily by reference to
classifications made by independent firms, such as Standard & Poor's (for
example, companies classified as "Information Technology" companies), and by
identifying companies that derive a substantial portion of their revenues from
the manufacture, sale and/or service of technological products. Except as
indicated above, the Fund is not required to invest exclusively in a particular
business sector or industry.

         The portfolio manager selects stocks for the Fund using a "growth"
style. The portfolio manager seeks to identify companies with well-defined
"wealth creating" characteristics, including superior earnings growth (relative
to companies in the same industry or the market as a whole), high profitability
and consistent, predictable earnings. In addition, through fundamental research,
the portfolio manager seeks to identify companies that are gaining market share,
have superior management and possess a sustainable competitive advantage, such
as superior or innovative products, personnel and distribution systems. The Fund
looks to sell a stock when the portfolio manager believes that earnings or
market sentiment are disappointing, if the company does not meet or exceed
consensus estimates on revenues and/or earnings or if an alternative investment
is more attractive.

         Although the Fund invests principally in common stocks, the Fund may
also invest to a significant degree in the securities of smaller-capitalization
companies and in other types of equity securities, including preferred stocks
and convertible securities. The Fund may invest in securities issued in initial
public offerings ("IPOs"). The Fund may invest up to 15% of its assets in
foreign securities, except that it may invest without limit in American
Depository Receipts.

         In response to unfavorable market and other conditions, the Fund may
make temporary investments of some or all of its assets in high-quality fixed
income securities. This would be inconsistent with the Fund's investment
objective and principal strategies.

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

</TABLE>

(1)       Other Expenses, which are based on estimated amounts for the Fund's
     initial fiscal year, reflect a 0.25% Administrative Fee paid by the class
     and [0.04%] representing the Fund's organizational expenses as attributed
     to the class ("Organizational Expenses").


(2)       Net Expenses reflect the effect of a contractual agreement by PIMCO
     Advisors to waive, reduce or reimburse its Administrative Fees for each
     class in an amount that, in essence, is equal to the Fund's Organizational
     Expenses attributed to the class. Because the Organizational Expenses will
     all be accounted for in the Fund's initial fiscal year, the Fund's
     reasonable expectation is that the relevant conditions will not continue
     after the Fund's fiscal year ending June 30, 2001.

Examples. The Examples below are intended to help you compare the cost of
investing in Institutional Class or Administrative Class 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 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.(1)

         The Fund seeks to achieve its investment objective by normally
investing at least 65% of its assets in common stocks of companies principally
engaged in the development, manufacture or sale of new, creative or different,
or "innovative," communications services or communications equipment. These
companies may (but are not required to) include, for example, companies that
provide traditional local and long-distance telephone service or equipment,
companies that provide cellular, paging, local and wide area product networks or
equipment, companies that provide satellite, microwave and cable television or
equipment, and companies involved in new technologies such as fiber optics,

     Expenses will all be accounted for in the Fund's initial fiscal year, the
     Fund's reasonable expectation is that the relevant conditions will not
     continue after the Fund's fiscal year ending June 30, 2001.

Examples. The Examples below are intended to help you compare the cost of
investing in Institutional Class or Administrative Class 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 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.(1)

         The Fund seeks to achieve its investment objective by normally
investing at least 65% of its assets in an international portfolio of common
stocks and other equity securities of companies located in Asia. The Fund will
primarily invest in securities of companies located in the Far East, including
Australia, China, Hong Kong, Indonesia, India, Malaysia, New Zealand, the
Philippines, Singapore, South Korea, Taiwan and Thailand but excluding Japan,
although the Fund will not necessarily be invested in all of these countries at
any time. The Fund may also invest in securities of foreign issuers traded on
U.S. securities markets, but will normally not invest in U.S. issuers. However,
the Fund has no other limits on geographic asset distribution and may invest in
any foreign securities market in the world. The Fund invests most of its assets
in foreign securities which trade in currencies other than the U.S. dollar and
may invest directly in foreign currencies.

         The portfolio manager selects securities for the Fund using a
research-driven "bottom-up" approach that seeks to identify companies with
above-average long-term growth prospects and attractive valuations and that
possess a sustainable competitive advantage, such as superior or innovative
products, personnel and distribution systems. In selecting stocks, the portfolio
manager analyzes a broad range of company fundamentals, such as long-term growth
prospects, price-to-earnings ratios and other valuation measures, dividend and
profit growth, balance sheet strength and return on assets. A stock's liquidity
and volatility are also considered. The portfolio manager sells stocks in order
to adjust or rebalance the Fund's portfolio and to replace companies with
weakening fundamentals.

         The Fund may utilize foreign currency exchange contracts and derivative
instruments (such as stock index futures contracts), primarily for portfolio
management and hedging purposes. The Fund may to a limited degree invest in
equity securities other than common stocks (such as equity-linked securities,
preferred stocks and convertible securities) and may invest up to 10% of its
assets in other investment companies. In response to unfavorable market and
other conditions, the Fund may make temporary investments of some or all of its
assets in foreign and domestic fixed income securities and in equity securities
of U.S. issuers. This would be inconsistent with the Fund's investment objective
and principal strategies.

</TABLE>

         The Fund seeks to achieve its investment objective by normally
investing at least 65% of its assets in an international portfolio of common
stocks and other equity securities of companies located throughout the world.
Although the Fund normally invests in issuers from at least five different
countries, including the United States, it may at times invest in fewer than
five countries, or even a single country. The Fund typically invests in
approximately 30 to 60 stocks. Although the Fund invests primarily in developed
market countries, it may also invest in developing, or "emerging," markets. The
Fund has no other limits on geographic asset distribution and may invest in any
foreign securities market in the world. The Fund invests most of its assets in
foreign securities which trade in currencies other than the U.S. dollar and may
invest directly in foreign currencies.

         The portfolio manager selects securities for the Fund using a
research-driven "bottom-up" approach that seeks to utilize the Sub-Adviser's
global research capabilities to identify companies with above-average long-term
growth prospects and attractive valuations and that possess a sustainable
competitive advantage, such as superior or innovative products, personnel and
distribution systems. The portfolio manager seeks to select those stocks with
the best long-term performance expectations, using a broad range of company
fundamentals, such as long-term growth prospects, price-to-earnings ratios and
other valuation measures, dividend and profit growth, balance sheet strength and
return on assets. The portfolio managers sell stocks in order to adjust or
rebalance the Fund's portfolio and to replace companies with weakening
fundamentals.

         The Fund may utilize foreign currency exchange contracts and derivative
instruments (such as stock index futures contracts), primarily for portfolio
management and hedging purposes. The Fund may to a limited degree invest in
equity securities other than common stocks (such as equity-linked securities,
preferred stocks and convertible securities) and may invest up to 10% of its
assets in other investment companies. In response to unfavorable market and
other conditions, the Fund may make temporary investments of some or all of its
assets in foreign and domestic fixed income securities and in equity securities
of U.S. issuers. This would be inconsistent with the Fund's investment objective
and principal strategies.

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 summarized 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 each 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.

Market Risk

The market price of securities owned by a Fund may go up or down, sometimes
rapidly or unpredictably. Each of the Funds normally invests most of its assets
in common stocks and/or other equity securities. A principal risk of investing
in each Fund is that the equity securities in its portfolio will decline in
value due to factors affecting equity securities markets generally or particular
industries represented in those markets. The values of equity securities 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 Risk

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

Growth Securities Risk

Each Fund emphasizes investments in equity securities of companies that its
portfolio manager believes will experience relatively rapid earnings growth. The
Funds place particular emphasis on growth securities. Growth securities
typically trade at higher multiples of current earnings than other securities.
Therefore, the values of growth securities may be more sensitive to changes in
current or expected earnings than the values of other securities.

Value Securities Risk

The Funds may invest in companies that may not be expected to experience
significant earnings growth, but whose securities its portfolio manager believes
are selling at a price lower than their true value. The New Asia, Europe Growth
and Emerging Markets Funds place particular emphasis on value securities.
Companies that issue value securities may have experienced adverse business
developments or may be subject to special risks that have caused their
securities to be out of favor. If a portfolio manager's assessment of a
company's prospects is wrong, or if the market does not recognize the value of
the company, the price of its securities may decline or may not approach the
value that the portfolio manager anticipates.

Smaller Company Risk

The general risks associated with equity securities and liquidity risk are
particularly pronounced for securities of companies with smaller market
capitalizations. These companies may have limited product lines, markets or
financial resources or they may depend on a few key employees. Securities of
smaller companies may trade less frequently and in lesser volume than more
widely held securities and their values may fluctuate more sharply than other
securities. They may also trade in the over-the-counter market or on a regional
exchange, or may otherwise have limited liquidity. The Small-Cap Technology Fund
has substantial exposure to this risk because it invests primarily in the
securities of companies with market

                                       23
<PAGE>


capitalizations below $200 million. The Healthcare Innovation, Internet
Innovation, Telecom Innovation, Electronics Innovation, New Asia, Europe Growth,
Select World and Emerging Markets Funds also have significant exposure to this
risk.

IPO Risk

The Funds, particularly the Healthcare Innovation, Internet Innovation,
Small-Cap Technology, Telecom Innovation and Electronics Innovation Funds, may
purchase securities in initial public offerings (IPOs). These securities are
subject to many of the same risks of investing in companies with smaller market
capitalizations. Securities issued in IPOs have no trading history, and
information about the companies may be available for very limited periods. In
addition, the prices of securities sold in IPOs may be highly volatile. At any
particular time or from time to time a Fund may not be able to invest in
securities issued in IPOs, or invest to the extent desired, because, for
example, only a small portion of the securities being offered in an IPO may be
made available to the Fund or because under certain market conditions few
companies may issue securities in IPOs. In addition, as a Fund increases in
size, the impact of IPOs on the Fund's performance will generally decrease.

Liquidity Risk

All of the Funds are subject to liquidity risk. Liquidity risk exists when
particular investments are difficult to purchase or sell, possibly preventing a
Fund from selling such illiquid securities at an advantageous time or price.
Funds with principal investment strategies that involve securities of companies
with smaller market capitalizations, foreign securities, derivatives or
securities with substantial market and/or credit risk tend to have the greatest
exposure to liquidity risk.

Derivatives Risk

All of the Funds may use derivatives, which are financial contracts whose 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 may sometimes use derivatives 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, which increases opportunities for gain but
also involves greater risk of loss due to 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, 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. In addition, a Fund's use of
derivatives may increase or accelerate the amount of taxes payable by
shareholders. 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.

Sector Specific Risks

In addition to other risks, Funds that invest a substantial portion of their
assets in related industries (or "sectors") may have greater risk because
companies in these sectors may share common characteristics and may react
similarly to market developments. The Funds that "concentrate" their investments
in certain sectors and some of the risks of investing in those sectors are
provided below.

         Healthcare Related Risk. The Healthcare Innovation Fund concentrates
         its investments in the healthcare industry. Therefore, it is subject to
         risks particular to that industry, including rapid obsolescence of
         products and services, patent expirations, risks associated with new
         regulations and changes to existing regulations, changes in government
         subsidy and reimbursement levels, and risks associated with the
         government approval process.

         Internet Related Risk. The Internet Innovation Fund is subject to risks
         prevalent in the Internet sector, such as the risks of rapid

         limited earnings, security price volatility and limited operating
         histories, because it concentrates its investments in that sector.

         Technology Related Risk. Because the Small-Cap Technology Fund
         concentrates its investments in the technology sector, it is subject to
         risks prevalent in that sector, such as the risks of short product
         cycles and rapid obsolescence of products and services, competition
         from new and existing companies, significant losses and/or limited
         earnings, security price volatility and limited operating histories.

         Telecommunications Related Risk. The Telecom Innovation Fund
         concentrates its investments in the telecommunications industry.
         Therefore, it is subject to risks particularly affecting that industry,
         such as risks associated with government regulation of products,
         services and rates of return, new regulations and changes to existing
         regulations, changes to government subsidy levels, and increasing
         competition.

         Electronics Related Risk. The Electronics Innovation Fund is subject to
         risks prevalent in the electronics sector, such as the risks of short
         product cycles and rapid obsolescence of products and services, intense
         competition, significant losses and/or limited earnings, security price
         volatility and limited operating histories, because it concentrates its
         investments in that sector.

Foreign (non-U.S.) Investment Risk

A Fund that invests in foreign securities, and particularly the New Asia, Europe
Growth, Select World and Emerging Markets Funds, may experience more rapid and
extreme changes in value than Funds that invest exclusively in securities of
U.S. issuers or securities that trade exclusively in U.S. markets. The
securities markets of many foreign countries are relatively small, with a
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. To the extent that a Fund, such as New
Asia, Europe Growth, Select World and Emerging Markets Funds, invests a
significant portion of its assets in a narrowly defined geographic area such as
Europe, Asia or South America, the Fund will generally have more exposure to
regional economic risks associated with foreign investments. Adverse conditions
in certain regions (such as Southeast Asia) can also adversely affect securities
of other countries whose economies appear to be unrelated. In addition, special
U.S. tax considerations may apply to a Fund's investment in foreign securities.

Emerging Markets Risk

Foreign investment risk may be particularly high to the extent that a Fund
invests in emerging market securities of issuers based 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. The Emerging Markets Fund is
particularly susceptible to these risks because it invests principally in
companies located in emerging markets countries. The New Asia and Select World
Funds also have substantial exposure to these risks because these Funds may
invest a significant portion of their assets in emerging market securities. In
addition, risks associated with investing in a narrowly defined geographic area
(discussed above under "Foreign (non-U.S.) Investment Risk") are more pronounced
for the Funds that invest in emerging markets.

Currency Risk

Funds that invest directly in foreign currencies or in securities that trade in,
and receive revenues in, foreign 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. The New Asia, Europe Growth, Select World and Emerging
Markets Funds are particularly sensitive to currency risk. 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.

                                       25
<PAGE>

Focused Investment Risk

Focusing Fund investments in a small number of issuers, industries or foreign
currencies or regions increases risk. Funds, that invest in a relatively small
number of issuers may have more risk because changes in the value of a single
security or the impact of a single economic, political or regulatory occurrence
may have a greater adverse impact on the Fund's net asset value. Some of those
issuers also may present substantial credit or other risks. The New Asia, Europe
Growth, Select World and Emerging Markets Funds may be subject to increased risk
to the extent that they focus their investments in securities denominated in a
particular foreign currency or in a narrowly defined geographic area such as
Europe, Asia or South America, because companies in those areas may share common
characteristics and react similarly to market developments. Also, the Funds may
from time to time have greater risk to the extent they invest a substantial
portion of their assets in related industries such as "financial and business
services" or "technology" which may also share common characteristics and react
similarly to market developments.

Leveraging Risk

Leverage, including borrowing, will cause the value of a Fund's shares to be
more volatile than if the Fund did not use leverage. This is because leverage
tends to exaggerate the effect of any increase or decrease in the value of a
Fund's portfolio securities. The Funds may engage in transactions or purchase
instruments that give rise to forms of leverage. Such transactions and
instruments may include, among others, the use of reverse repurchase agreements
and other borrowings, the investment of collateral from loans of portfolio
securities, or the use of when-issued, delayed-delivery or forward commitment
transactions. The use of derivatives may also involve leverage. The use of
leverage may also cause a Fund to liquidate portfolio positions when it would
not be advantageous to do so in order to satisfy its obligations or to meet
segregation requirements.

Interest Rate Risk

To the extent that Funds purchase fixed income securities for investment or
defensive purposes, they will be subject to interest rate risk, a market risk
relating to investments in fixed income securities such as bonds and notes. As
interest rates rise, the value of fixed income securities in a Fund's portfolio
are likely to decrease. Securities with longer "durations" (defined below) tend
to be more sensitive to changes in interest rates, usually making them more
volatile than securities with shorter durations. 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. 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 Risk

All of the Funds are subject to credit risk. This is the risk that the issuer or
the guarantor of a fixed 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 their credit ratings.

Management Risk

Each Fund is subject to management risk because it is an actively managed
investment portfolio. PIMCO Advisors, the Sub-Advisers 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.

Management of the Funds

Investment Adviser and Administrator

PIMCO Advisors serves as the investment adviser and the administrator (serving
in its capacity as administrator, the "Administrator") for the Funds. Subject to
the supervision of the Board of Trustees, PIMCO Advisors is responsible for
managing, either directly or through others selected by it, the investment
activities of the Funds and the Funds' business affairs and other administrative
matters.

PIMCO Advisors is located at 800 Newport Center Drive, Newport Beach, California
92660. Organized in 1987, PIMCO Advisors provides investment management and
advisory services to private accounts of institutional and individual clients
and to mutual funds. As of [ ], 2000, PIMCO Advisors and its subsidiary
partnerships had more than $[ ] billion in assets under management.

PIMCO Advisors has retained its subsidiary PIMCO/Allianz International Advisors
LLC to manage the investments of the New Asia, Europe Growth, Select World and
Emerging Markets Funds The PIMCO Equity Advisors division of PIMCO Advisors
manages the investments of the Healthcare Innovation, Internet Innovation,
Small-Cap Technology, Telecom Innovation and Electronics Innovation Funds (PIMCO
Equity Advisors and PIMCO/Allianz International Advisors LLC are each referred
to as a "Sub-Adviser" in this prospectus). See "Sub-Advisers" below.

PIMCO Advisors has retained its affiliate, Pacific Investment Management Company
LLC, to provide various administrative and other services required by the Funds
in its capacity as sub-administrator. PIMCO Advisors and the sub-administrator
may retain other affiliates to provide certain of these services.

Advisory Fees

Each Fund pays PIMCO Advisors fees in return for providing or arranging for the
provision of investment advisory services. In the case of Funds for which PIMCO
Advisors has retained PIMCO/Allianz International Advisors LLC, PIMCO Advisors
(and not the Fund) pays a portion of the advisory fees it receives to the
Sub-Adviser in return for its services.

The Funds will pay monthly advisory fees to PIMCO Advisors at the following
annual rates (stated as a percentage of the average daily net assets of each
Fund taken separately):


Fund                                                         Advisory Fees

Administrative Fees

Each Fund pays for the administrative services it requires under a fee structure
which is essentially fixed. Institutional and Administrative Class shareholders
of each Fund pay an administrative fee to PIMCO Advisors, computed as a
percentage of the Fund's assets attributable in the aggregate to those classes
of shares. PIMCO Advisors, in turn, provides or procures administrative services
for Institutional and Administrative Class shareholders and also bears the costs
of most third-party services required by the Funds, including audit, custodial,
portfolio accounting, legal, transfer agency and printing costs. The Funds do
bear other expenses which are not covered under the administrative fee which may
vary and affect the total level of expenses paid by Institutional and
Administrative Class shareholders, such as brokerage fees, commissions and other
transaction expenses, costs of borrowing money, including interest expenses, and
fees and expenses of the Trust's disinterested Trustees.

In managing the portfolios of the New Asia and Emerging Markets Funds, Mr.
Kaldun will be assisted by Mr. Ian Lui of Allianz Asset Management (HK) Limited
in Singapore and his Allianz research team.

Each Fund pays for the administrative services it requires under a fee structure
which is essentially fixed. Institutional and Administrative Class shareholders
of each Fund pay an administrative fee to PIMCO Advisors, computed as a
percentage of the Fund's assets attributable in the aggregate to those classes
of shares. PIMCO Advisors, in turn, provides or procures administrative services
for Institutional and Administrative Class shareholders and also bears the costs
of most 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 that Institutional and Administrative Class shareholders
of each Fund bear expenses for administrative services at a level that is
precise and predictable under ordinary circumstances. The Funds do bear other
expenses which are not covered under the administrative fee which may vary and
effect the total level of expenses paid by Institutional and Administrative
Class shareholders, such as brokerage fees, commissions and other transaction
expenses, costs of borrowing money, including interest expenses, and fees and
expenses of the trust's disinterested trustees.

Adviser/Sub-Adviser Relationship

Shareholders of each Fund have approved a proposal permitting PIMCO Advisors to
enter into new or amended sub-advisory agreements with one or more sub-advisers
with respect to each Fund without obtaining shareholder approval of such
agreements, subject to the conditions of an exemptive order that has been
granted by the Securities and Exchange Commission. One of the conditions
requires the Board of Trustees to approve any such agreement. In addition, the
exemptive order prohibits PIMCO Advisors from entering into sub-advisory
agreements with affiliates of PIMCO Advisors without shareholder approval,
unless those affiliates are substantially wholly-owned by PIMCO Advisors. PIMCO
Advisors has the ultimate responsibility to oversee the Sub-Advisers and to
recommend their hiring, termination and replacement.

Distributor

The Trust's Distributor is PIMCO Funds Distributors LLC, 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.

Investment Options -
Institutional Class and Administrative Class Shares

The Trust offers investors Institutional Class and Administrative Class shares
of the Funds in this Prospectus.

The Trust does not charge any sales charges (loads) or other fees in connection
with purchases, sales (redemptions) or exchanges of Institutional Class or
Administrative Class shares.

Administrative Class shares are generally subject to a higher level of operating
expenses than Institutional Class shares due to the additional service and/or
distribution fees paid by Administrative Class shares as described below.
Therefore, Institutional Class shares will generally pay higher dividends and
have a more favorable investment return than Administrative Class shares.

Service and Distribution (12b-1) Fees--Administrative Class Shares. The Trust
has adopted an Administrative Services Plan for the Administrative Class shares
of each Fund. It has also adopted a Distribution Plan for the Administrative
Class shares of each Fund. Each Plan has been adopted in accordance with the
requirements of Rule 12b-1 under the Investment Company Act of 1940 and is
administered in accordance with that rule. However, shareholders do not have the
voting rights set forth in Rule 12b-1 with respect to the Administrative
Services Plan.

Each Plan allows the Funds to use its Administrative Class assets to reimburse
financial intermediaries that provide services relating to Administrative Class
shares. The Distribution Plan permits reimbursement for expenses in connection
with the distribution and marketing of Administrative Class shares and/or the
provision of shareholder services to Administrative Class shareholders. The
Administrative Services Plan permits reimbursement for services in connection
with the administration of plans or programs that use Administrative Class
shares of the Funds as their funding medium and for related expenses.

In combination, the Plans permit a Fund to make total reimbursements at an
annual rate of up to 0.25% of the Fund's average daily net assets attributable
to its Administrative Class shares. The same entity may not receive both
distribution and administrative services fees with respect to the same
Administrative Class assets, but may receive fees under each Plan with respect
to separate assets. Because these fees are paid out of a Fund's Administrative
Class assets on an ongoing basis, over time they will increase the cost of an
investment in Administrative Class shares and may cost an investor more than
other types of sales charges.

Arrangements with Service Agents. Institutional Class and Administrative Class
shares of the Funds may 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 and/or distribution fees paid
with respect to Administrative Class shares. Service agents may impose
additional or different conditions than the Trust on purchases, redemptions or
exchanges of Fund shares by their customers. Service agents may also
independently establish and charge their customers transaction fees, account
fees and other amounts in connection with purchases, sales and redemptions of
Fund shares in addition to any fees charged by the Trust. These additional fees
may vary over time and would increase the cost of the customer's investment and
lower investment returns. 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, redemptions and
exchanges. Shareholders who are customers of service agents should consult their
service agents for information regarding these fees and conditions.

                                       31

Purchases, Redemptions and Exchanges

Purchasing Shares

Investors may purchase Institutional Class and Administrative Class shares of
the Funds at the relevant net asset value ("NAV") of that class without a sales
charge or other fee.

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 their customers' investments in the Funds.

Administrative Class shares are offered primarily through employee benefit plan
alliances, broker-dealers and other intermediaries, and each Fund pays service
and/or distribution fees to these entities for services they provide to
Administrative Class shareholders.

Pension and profit-sharing plans, employee benefit trusts and employee benefit
plan alliances and "wrap account" programs established with broker-dealers or
financial intermediaries may purchase shares of either class only if the plan or
program for which the shares are being acquired will maintain an omnibus or
pooled account for each Fund and will not require a Fund to pay any type of
administrative payment per participant account to any third party.

Investment Minimums. The minimum initial investment for shares of either class
is $5 million, except that the minimum initial investment for a registered
investment adviser purchasing Institutional Class shares for its clients through
omnibus accounts is $250,000 per Fund. At the discretion of PIMCO Advisors, the
minimum initial investment may be waived for Institutional or Administrative
Class shares offered to clients of PIMCO Equity Advisors and [Allianz Sub], and
their affiliates, and to the benefit plans of PIMCO Advisors and its affiliates.
In addition, the minimum initial investment does not apply to Institutional
Class shares offered through fee-based programs sponsored and maintained by a
registered broker-dealer and approved by the Distributor in which each investor
pays an asset based fee at an annual rate of at least 0.50% of the assets in the
account to a financial intermediary for investment advisory and/or
administrative services.

The Trust and the Distributor may waive the minimum initial investment for other
categories of investors at their discretion.

The investment minimums discussed in this section and the limitations set forth
in "Investment Limitations" below do not apply to participants in PIMCO Advisors
Portfolio Strategies, a managed product sponsored by PIMCO Advisors.

Timing of Purchase Orders and Share Price Calculations. A purchase order
received by the Trust's transfer agent, National Financial Data Services (the
"Transfer Agent"), prior to the close of regular trading (normally 4:00 p.m.,
Eastern time) on the New York Stock Exchange, on a day the Trust is open for
business, together with payment made in one of the ways described below, will be
effected at that day's net asset value ("NAV"). An order received after the
close of regular trading on the New York Stock Exchange will be effected at the
NAV determined on the next business day. However, orders received by certain
retirement plans and other financial intermediaries on a business day prior to
the close of regular trading on the New York Stock Exchange and communicated to
the Transfer Agent prior to 9:00 a.m., Eastern time, on the following business
day will be effected at the NAV determined on the prior business day. The Trust
is "open for business" on each day the New York Stock Exchange is open for
trading, which excludes the following holidays: New Year's Day, Martin Luther
King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day,
Labor Day, Thanksgiving Day and Christmas Day. Purchase orders will be accepted
only on days on which the Trust is open for business.

Initial Investment. Investors may open an account by completing and signing a
Client Registration Application and mailing it to PIMCO Funds at 840 Newport
Center Drive, Suite 300, Newport Beach, California 92660. A Client Registration
Application may be obtained by calling 1-800-927-4648.

Except as described below, an investor may purchase Institutional Class and
Administrative Class shares only by wiring federal funds to the Transfer Agent,
National Financial Data Services, 330 West 9th Street, 4th Floor, Kansas City,
Missouri 64105. Before wiring federal funds, the investor must telephone the
Trust at 1-800-927-4648 to receive instructions for wire

                                       32
<PAGE>

transfer and must provide the following information: name of authorized person,
shareholder name, shareholder account number, name of Fund and share class,
amount being wired, and wiring bank name.

An investor may purchase shares without first wiring federal funds if the
proceeds of the investment are derived from an advisory account the investor
maintains with PIMCO Advisors or one of its affiliates, from surrender or other
payment from an annuity, insurance, or other contract held by Pacific Life
Insurance Company, or from an investment by broker-dealers, institutional
clients or other financial intermediaries which have established a shareholder
servicing relationship with the Trust on behalf of their customers.

Additional Investments. An investor may purchase additional Institutional Class
and Administrative Class shares of the Funds at any time by calling the Trust
and wiring federal funds to the Transfer Agent as outlined above.

Other Purchase Information. Purchases of a Fund's Institutional Class and
Administrative Class shares will be made in full and fractional shares. In the
interest of economy and convenience, certificates for shares will not be issued.

The Trust and the Distributor each reserves the right, in its sole discretion,
to suspend the offering of shares of the Funds or to reject any purchase order,
in whole or in part, when, in the judgment of management, such suspension or
rejection is in the best interests of the Trust.

An investor should invest in the Funds for long-term investment purposes only.
The Trust and PIMCO Advisors each reserves the right to restrict purchases of
Fund shares (including exchanges) when a pattern of frequent purchases and sales
made in response to short-term fluctuations in share price appears evident.
Notice of any such restrictions, if any, will vary according to the particular
circumstances.

Institutional Class and Administrative Class shares of the Trust are not
qualified or registered for sale in all states. Investors should inquire as to
whether shares of a particular Fund are available for offer and sale in the
investor's state of residence. Shares of the Trust may not be offered or sold in
any state unless registered or qualified in that jurisdiction or unless an
exemption from registration or qualification is available.

Subject to the approval of the Trust, an investor may purchase shares of a Fund
with liquid securities that are eligible for purchase by the Fund (consistent
with the Fund's investment policies and restrictions) and that have a value that
is readily ascertainable in accordance with the Trust's valuation policies.
These transactions will be effected only if PIMCO Advisors or a Sub-Adviser
intends to retain the security in the Fund as an investment. Assets purchased by
a Fund in such a transaction will be valued in generally the same manner as they
would be valued for purposes of pricing the Fund's shares, if such assets were
included in the Fund's assets at the time of purchase. The Trust reserves the
right to amend or terminate this practice at any time.

Retirement Plans. Shares of the Funds are available for purchase by retirement
and savings plans, including Keogh plans, 401(k) plans, 403(b) custodial
accounts, and Individual Retirement Accounts. The administrator of a plan or
employee benefits office can provide participants or employees with detailed
information on how to participate in the plan and how to elect a Fund as an
investment option. Participants in a retirement or savings plan may be permitted
to elect different investment options, alter the amounts contributed to the
plan, or change how contributions are allocated among investment options in
accordance with the plan's specific provisions. The plan administrator or
employee benefits office should be consulted for details. For questions about
participant accounts, participants should contact their employee benefits
office, the plan administrator, or the organization that provides recordkeeping
services for the plan. Investors who purchase shares through retirement plans
should be aware that plan administrators may aggregate purchase and redemption
orders for participants in the plan. Therefore, there may be a delay between the
time the investor places an order with the plan administrator and the time the
order is forwarded to the Transfer Agent for execution.

Redeeming Shares

Redemptions by Mail. An investor may redeem (sell) Institutional Class and
Administrative Class shares by submitting a written request to PIMCO Funds at
840 Newport Center Drive, Suite 300, Newport Beach, California 92660. The
redemption request should state the Fund from which the shares are to be
redeemed, the class of shares, the number or dollar amount of the shares to be
redeemed and the account number. The request must be signed exactly as the names
of the registered owners

                                       33
<PAGE>

appear on the Trust's account records, and the request must be signed by the
minimum number of persons designated on the Client Registration Application that
are required to effect a redemption.

Redemptions by Telephone or Other Wire Communication. An investor that elects
this option on the Client Registration Application (or subsequently in writing)
may request redemptions of shares by calling the Trust at 1-800-927-4648, by
sending a facsimile to 1-949-725-6830, or by other means of wire communication.
Investors should state the Fund and class from which the shares are to be
redeemed, the number or dollar amount of the shares to be redeemed and the
account number. Redemption requests of an amount of $10 million or more may be
initiated by telephone, but must be confirmed in writing by an authorized party
prior to processing.

In electing a telephone redemption, the investor authorizes Pacific Investment
Management Company and the Transfer Agent to act on telephone instructions from
any person representing himself to be the investor, and reasonably believed by
Pacific Investment Management Company or the Transfer Agent to be genuine.
Neither the Trust nor the Transfer Agent may be liable for any loss, cost or
expense for acting on instructions (whether in writing or by telephone) believed
by the party receiving such instructions to be genuine and in accordance with
the procedures described in this Prospectus. Shareholders should realize that by
electing the telephone or wire redemption option, they may be giving up a
measure of security that they might have if they were to redeem their shares in
writing. Furthermore, interruptions in telephone service may mean that a
shareholder will be unable to effect a redemption by telephone when desired. The
Transfer Agent also provides written confirmation of transactions initiated by
telephone as a procedure designed to confirm that telephone instructions are
genuine (written confirmation is also provided for redemption requests received
in writing). All telephone transactions are recorded, and Pacific Investment
Management Company or the Transfer Agent may request certain information in
order to verify that the person giving instructions is authorized to do so. The
Trust or Transfer Agent may be liable for any losses due to unauthorized or
fraudulent telephone transactions if it fails to employ reasonable procedures to
confirm that instructions communicated by telephone are genuine. All
redemptions, whether initiated by letter or telephone, will be processed in a
timely manner, and proceeds will be forwarded by wire in accordance with the
redemption policies of the Trust detailed below. See "Other Redemption
Information."

Shareholders may decline telephone exchange or redemption privileges after an
account is opened by instructing the Transfer Agent in writing at least seven
business days prior to the date the instruction is to be effective. Shareholders
may experience delays in exercising telephone redemption privileges during
periods of abnormal market activity. During periods of volatile economic or
market conditions, shareholders may wish to consider transmitting redemption
orders by telegram, facsimile or overnight courier.

Defined contribution plan participants may request redemptions by contacting the
employee benefits office, the plan administrator or the organization that
provides recordkeeping services for the plan.

Other Redemption Information. Redemption requests for Fund shares are effected
at the NAV per share next determined after receipt of a redemption request by
the Trust or its designee. The request must properly identify all relevant
information, such as account number, redemption amount (in dollars or shares)
and the Fund name, and must be executed or initialed by the appropriate
signatories. A redemption request received by the Trust or its designee prior to
the close of regular trading on the New York Stock Exchange (normally 4:00 p.m.,
Eastern time), on a day the Trust is open for business, is effective on that
day. A redemption request received after that time becomes effective on the next
business day.

Redemption proceeds will ordinarily be wired to the investor's bank within three
business days after the redemption request, but may take up to seven business
days. Redemption proceeds will be sent by wire only to the bank name designated
on the Client Registration Application. The Trust may suspend the right of
redemption or postpone the payment date at times when the New York Stock
Exchange is closed, or during certain other periods as permitted under the
federal securities laws.

For shareholder protection, a request to change information contained in an
account registration (for example, a request to change the bank designated to
receive wire redemption proceeds) must be received in writing, signed by the
minimum number of persons designated on the Client Registration Application that
are required to effect a redemption, and accompanied by a signature guarantee
from any eligible guarantor institution, as determined in accordance with the
Trust's procedures. Shareholders should inquire as to whether a particular
institution is an eligible guarantor institution. A signature guarantee cannot
be provided by a notary public. In addition, corporations, trusts, and other
institutional organizations are required to furnish evidence of the authority of
the persons designated on the Client Registration Application to effect
transactions for the organization.

                                       34
<PAGE>

Due to the relatively high cost of maintaining small accounts, the Trust
reserves the right to redeem Institutional Class and Administrative Class shares
in any account for their then-current value (which will be promptly paid to the
investor) if at any time, due to redemption by the investor, the shares in the
account do not have a value of at least $100,000. A shareholder will receive
advance notice of a mandatory redemption and will be given at least 30 days to
bring the value of its account up to at least $100,000. This mandatory
redemption policy does not apply to participants in PIMCO Advisors Portfolio
Strategies, a managed product sponsored by PIMCO Advisors.

The Trust agrees to redeem shares of each Fund solely in cash 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 reserves the right to 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. It is highly unlikely that shares
would ever be redeemed in kind. When shares are redeemed in kind, the redeeming
shareholder should expect to incur transaction costs upon the disposition of the
securities received in the distribution.

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.

Exchange Privilege

Except as provided below, an investor may exchange Institutional Class or
Administrative Class shares of a Fund for shares of the same class of any other
Fund or other series of the Trust that offers that class based on the respective
NAVs of the shares involved. An exchange may be made by following the redemption
procedure described above under "Redemptions by Mail" or, if the investor has
elected the telephone redemption option, by calling the Trust at 1-800-927-4648.
An investor may also exchange shares of a Fund for shares of the same class of a
series of PIMCO Funds: Pacific Investment Management Series, an affiliated
mutual fund family composed primarily of fixed income portfolios managed by
Pacific Investment Management Company, subject to any restrictions on exchanges
set forth in the applicable series' prospectus(es). Shareholders interested in
such an exchange may request a prospectus for these other series by contacting
PIMCO Funds: Pacific Investment Management Series at the same address and
telephone number as the Trust.

An investor may exchange shares only with respect to Funds or other eligible
series that are registered in the investor's state of residence or where an
exemption from registration is available. In addition, an exchange is generally
a taxable event which will generate capital gains or losses, and special rules
may apply in computing tax basis when determining gain or loss. See "Tax
Consequences" in this Prospectus and "Taxation" in the Statement of Additional
Information.

The Trust reserves the right to refuse exchange purchases if, in the judgment of
PIMCO Advisors, 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 Advisors to be detrimental to the Trust or a
particular Fund. Currently, the Trust limits the number of "round trip"
exchanges investors 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 PIMCO 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. The Trust reserves the right to impose additional
restrictions on exchanges at any time, although it will attempt to give
shareholders 30 days' prior notice whenever it is reasonably able to do so.


How Fund Shares Are Priced

The net asset value ("NAV") of a Fund's Institutional and Administrative Class
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.

                                       35
<PAGE>

For purposes of calculating the 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 quotes are not readily available may be
valued, pursuant to guidelines established by the Board of Trustees, with
reference to other securities or 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. In particular, calculation of the NAV of the New Asia, Europe Growth,
Select World and Emerging Markets Funds may not take place contemporaneously
with the determination of the prices of foreign securities used in NAV
calculations.

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 their 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 or persons acting at their direction
pursuant to procedures approved by the Board of Trustees. Fair valuation may
also be used by the Board of Trustees if extraordinary events occur after the
close of the relevant market but prior to the NYSE Close.


Under certain circumstances, the per share NAV of the Administrative Class
shares of the Funds may be lower than the per share NAV of the Institutional
Class shares as a result of the daily expense accruals of the service and/or
distribution fees paid by Administrative Class 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 the two
classes.

Fund Distributions

Each Fund distributes substantially all of its net investment income to
shareholders in the form of dividends. A shareholder begins earning dividends on
Fund shares the day after the Trust receives the shareholder's 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, but dividends on Administrative Class
shares are expected to be lower than dividends on Institutional Class shares as
a result of the service and/or distribution fees applicable to Administrative
Class shares. 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.

                                       36
<PAGE>

A Fund's dividend and capital gain distributions with respect to a particular
class of shares will automatically be reinvested in additional shares of the
same class of the Fund at NAV unless the shareholder elects to have the
distributions paid in cash. A shareholder may elect to have distributions paid
in cash on the Client Registration Application or by submitting a written
request, signed by the appropriate signatories, indicating the account number,
Fund name(s) and wiring instructions.

For further information on distribution options, please contact the Trust at
1-800-927-4648.

Tax Consequences

Taxes on Fund Distributions. A shareholder subject to U.S. federal income tax
will be subject to tax on Fund distributions whether they are paid in cash or
reinvested in additional shares of the Funds. For federal income tax purposes,
Fund distributions will be taxable to the shareholder as either ordinary income
or capital gains.

Fund dividends (i.e., distributions of investment income) are taxable to
shareholders 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 the shareholder owned the shares. Distributions of
gains from investments that a Fund owned for more than 12 months will generally
be taxable to shareholders as capital gains. Distributions of gains from
investments that the Fund owned for 12 months or less will generally be taxable
as ordinary income.

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

Taxes on Redemptions or Exchanges of Shares. Any gain resulting from the sale of
Fund shares will generally be subject to federal income tax. When a shareholder
exchanges shares of a Fund for shares of another series, the transaction
generally 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.

A Note on Foreign Investments. A Fund's investment in foreign securities may be
subject to foreign withholding taxes. In that case, the Fund's yield on those
securities would be decreased. In addition, a Fund's investments in foreign
securities or foreign currencies may increase or accelerate the Fund's
recognition of ordinary income and may affect the timing or amount of the Fund's
distributions. Shareholders of the New Asia, Europe Growth, Select World and
Emerging Markets Funds may be entitled to claim a credit or deduction with
respect to foreign taxes.

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 local income tax laws to Fund
dividends and capital distributions. Please see the Statement of Additional
Information for additional information regarding the tax aspects of investing in
the Funds.

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 identified under "Summary
Information" above. It also describes characteristics and risks of additional
securities and investment techniques that are not necessarily principal
investments or strategies but may be used by the Funds from time to time. Most
of these securities and investment techniques are discretionary, which means
that the portfolio managers 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 must rely on the professional investment judgment
and skill of PIMCO Advisors, the Sub-Advisers 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.

Fixed Income Securities and Defensive Strategies

Fixed income securities are obligations of the issuer to make payments of
principal and/or interest on future dates, and include corporate and government
bonds, notes, certificates of deposit, commercial paper, convertible securities
and mortgage-backed and other asset-backed securities.

The Healthcare Innovation, Internet Innovation, Small-Cap Technology, Telecom
Innovation, Electronics Innovation, New Asia, Europe Growth, Select World and
Emerging Markets Funds will each invest primarily in common stocks, and may also
invest in other kinds of equity securities, including preferred stocks and
securities (including fixed income securities and warrants) convertible into or
exercisable for common stocks. Each of these Funds may invest a portion of their
assets in fixed income securities. The Funds may temporarily hold up to 100% of
their assets in short-term U.S. Government securities and other money market
instruments for defensive purposes in response to unfavorable market and other
conditions. The New Asia, Europe Growth, Select World and Emerging Markets Funds
may also hold up to 100% of their assets in other domestic fixed income, foreign
fixed income and equity securities principally traded in the U.S., including
obligations issued or guaranteed by a foreign government or its agencies,
authorities or instrumentalities, corporate bonds and American Depository
Receipts, for temporary defensive purposes.

The temporary defensive strategies described in this section would be
inconsistent with the investment objective and principal investment strategies
of each of the noted Funds and may adversely affect the Fund's ability to
achieve its investment objective.

Companies With Smaller Market Capitalizations

Each of the Funds may invest in securities of companies with market
capitalizations that are small compared to other publicly traded companies. The
Small-Cap Technology Fund invests primarily in smaller companies and is
especially sensitive to the risks described below. In addition, the Healthcare
Innovation, Internet Innovation, Telecom Innovation, Electronics Innovation, New
Asia, Europe Growth, Select World and Emerging Markets Funds generally have
significant exposure to these risks.

Companies which are smaller and less well-known or seasoned than larger, more
widely held companies may offer greater opportunities for capital appreciation,
but may also involve risks different from, or greater than, risks normally
associated with larger companies. Larger companies generally have greater
financial resources, more extensive research and development, manufacturing,
marketing and service capabilities, and more stability and greater depth of
management and technical personnel than smaller companies. Smaller companies may
have limited product lines, markets or financial resources or may depend on a
small, inexperienced management group. Securities of smaller companies may trade
less frequently and in lesser volume than more widely held securities and their
values may fluctuate more abruptly or erratically than securities of larger
companies. They may also trade in the over-the-counter market or on a regional
exchange, or may otherwise have limited liquidity. These securities may
therefore be more vulnerable to adverse market developments than securities of
larger companies. Also, there may be less publicly available information about
smaller companies or less market

                                       38
<PAGE>

interest in their securities as compared to larger companies, and it may take
longer for the prices of the securities to reflect the full value of a company's
earnings potential or assets.

Because securities of smaller companies may have limited liquidity, a Fund may
have difficulty establishing or closing out its positions in smaller companies
at prevailing market prices. As a result of owning large positions in this type
of security, a Fund is subject to the additional risk of possibly having to sell
portfolio securities at disadvantageous times and prices if redemptions require
the Fund to liquidate its securities positions. For these reasons, it may be
prudent for a Fund with a relatively large asset size to limit the number of
relatively small positions it holds in securities having limited liquidity in
order to minimize its exposure to such risks, to minimize transaction costs, and
to maximize the benefits of research. As a consequence, as a Fund's asset size
increases, the Fund may reduce its exposure to illiquid smaller capitalization
securities, which could adversely affect performance.


Initial Public Offerings

The Funds, particularly the Healthcare Innovation, Internet Innovation,
Small-Cap Technology, Telecom Innovation and Electronics Innovation Funds, may
purchase securities in initial public offerings (IPOs). These securities are
subject to many of the same risks of investing in companies with smaller market
capitalizations. Securities issued in IPOs have no trading history, and
information about the companies may be available for very limited periods. In
addition, the prices of securities sold in IPOs may be highly volatile. At any
particular time or from time to time a Fund may not be able to invest in
securities issued in IPOs, or invest to the extent desired, because, for
example, only a small portion of the securities being offered in an IPO may be
made available to the Fund or because under certain market conditions few
companies may issue securities in IPOs. In addition, as a Fund increases in
size, the impact of IPOs on the Fund's performance will generally decrease.

Foreign Securities


The New Asia, Europe Growth, Select World and Emerging Markets Funds normally
invest principally in securities of foreign issuers, securities traded
principally in securities markets outside the United States and/or securities
denominated in foreign currencies (together, "foreign securities"). The
Healthcare Innovation, Internet Innovation, Small-Cap Technology, Telecom
Innovation and Electronics Innovation Funds may invest up to 15% of their
respective assets in foreign securities, and may invest without limit in
ADRs.

All of the Funds may invest in American Depository Receipts ("ADRs"), European
Depository Receipts ("EDRs") and Global Depository Receipts ("GDRs"). ADRs are
dollar-denominated receipts issued generally by domestic banks and representing
the deposit with the bank of a security of a foreign issuer, and are publicly
traded on exchanges or over-the-counter in the United States. EDRs are receipts
similar to ADRs and are issued and traded in Europe. GDRs may be offered
privately in the United States and also traded in public or private markets in
other countries.

Investing in foreign securities involves special risks and considerations not
typically associated with investing in U.S. securities and shareholders should
consider carefully the substantial risks involved for Funds that invest in these
securities. 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, rate 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.

Emerging Market Securities

The Funds may invest in securities of issuers based in or that trade principally
in countries with developing (or "emerging market") economies. The Emerging
Markets Fund is particularly susceptible to these risks because it invests
principally in

                                       39
<PAGE>

companies located in emerging market countries. The New Asia and Select World
Funds also have substantial exposure to these risks because these Funds may
invest significant portions of their assets in emerging market 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; and possible repatriation of
investment income and capital. In addition, foreign investors may be required to
register the proceeds of sales, and future economic or political crises could
lead to price controls, forced mergers, expropriation or confiscatory taxation,
seizure, nationalization or the 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 market 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.


Special Risks of Investing in Russian and Other Eastern European Securities. The
Select World and Emerging Markets Funds may invest a significant portion of
their assets in securities of issuers located in Russia and in other Eastern
European countries. While investments in securities of such issuers are subject
generally to the same risks associated with investments in other emerging market
countries described above, the political, legal and operational risks of
investing in Russian and other Eastern European issuers, and of having assets
custodied within these countries, may be particularly acute. A risk of
particular note with respect to direct investment in Russian securities is the
way in which ownership of shares of companies is normally recorded. When a Fund
invests in a Russian issuer, it will normally receive a "share extract," but
that extract is not legally determinative of ownership. The official record of
ownership of a company's share is maintained by the company's share registrar.
Such share registrars are completely under the control of the issuer, and
investors are provided with few legal rights against such registrars.

Foreign Currencies

A Fund that invests directly in foreign currencies or in securities that trade
in, and receive revenues in, foreign currencies will be subject to currency
risk. The New Asia, Europe Growth, Select World and Emerging Markets Funds are
particularly sensitive to this risk.

Foreign currency exchange rates may fluctuate significantly over short periods
of time. They generally are determined by supply and demand 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. The Europe Growth Fund is especially susceptible
to risks associated with the introduction of the Euro because it invests
principally in European companies, many of which are located in European
Monetary Union countries. The Euro 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. The Funds may enter into forward foreign currency
exchange contracts, primarily to reduce the risks of adverse changes in foreign
exchange rates. In addition, the Funds may buy and sell foreign currency futures
contracts and options on foreign currencies and foreign currency 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.

                                       40
<PAGE>

Contracts to sell foreign currency would limit any potential gain which might be
realized by a Fund if the value of the hedged currency increases. A Fund may
enter into these contracts to hedge against foreign exchange risk arising from
the Fund's investment or anticipated investment in securities denominated in
foreign currencies. 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.

The New Asia, Europe Growth, Select World and Emerging Markets Funds may also
enter into these contracts for purposes of increasing exposure to a foreign
currency or to shift exposure to foreign currency fluctuations from one currency
to another. To the extent that it does so, a Fund will be subject to the
additional risk that the relative value of currencies will be different than
anticipated by the Fund's portfolio manager. The Funds 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. Each Fund will segregate assets determined
to be liquid by PIMCO Advisors or a Sub-Adviser 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.

Corporate Debt Securities

Corporate debt securities are subject to the risk of the issuer's inability to
meet principal and interest payments on the 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 durations tend to be more sensitive to
interest rate movements than those with shorter durations.

Convertible Securities

Each Fund may invest in convertible securities. Convertible securities are
generally preferred stocks and other securities, including fixed income
securities and warrants, that are convertible into or exercisable for common
stock at either a stated price or a stated 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. While convertible securities
generally offer lower interest or dividend yields than non-convertible fixed
income securities of similar quality, their value tends to increase as the
market value of the underlying stock increases and to decrease when the value of
the underlying stock decreases. Also, 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.

Derivatives

Each Fund may, but is not required to, use a number of 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. 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.

Examples of derivative instruments include options contracts, futures contracts,
options on futures contracts and swap agreements. The Funds may purchase and
sell (write) call and put options on securities, securities indexes and foreign
currencies. Each Fund may purchase and sell futures contracts and options
thereon with respect to securities, securities indexes and foreign currencies. 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 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.

                                       41
<PAGE>

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.

Leveraging 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 Advisors or a
Sub-Adviser 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 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 (taxed at ordinary income tax rates when distributed to
shareholders who are individuals) than if the Fund had not used such
instruments.

Equity-Linked Securities


The Funds may invest up to 15% of their assets in equity-linked securities.
Equity-linked securities are privately issued securities whose investment
results are designed to correspond generally to the performance of a specified
stock index or "basket" of stocks, or sometimes a single stock. To the extent
that a Fund invests in equity-linked securities whose return corresponds to the
performance of a foreign securities index or one or more of foreign stocks,
investing in equity-linked securities will involve risks similar to the risks of
investing in foreign equity securities. See "Foreign Securities" above. In
addition, an investing Fund bears the risk that the issuer of an equity-linked
security may default on its obligations under the security. Equity-linked
securities may be considered illiquid and thus subject to the Funds'
restrictions on investments in illiquid securities.

                                       42
<PAGE>

Credit Ratings and Unrated Securities

The Funds may invest in securities based on their credit ratings assigned by
rating agencies such as Moody's Investors Service, Inc. ("Moody's") and Standard
& Poor's Ratings Services ("S&P"). Moody's, S&P and other rating agencies are
private services that provide ratings of the credit quality of fixed income
securities, including convertible securities. The Appendix to the Statement of
Additional Information 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 risk. 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 Advisors and the Sub-Advisers do not rely
solely on credit ratings, and develop their 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.

High Yield Securities


Securities rated lower than Baa by Moody's or lower than BBB by S&P are
sometimes referred to as "high yield securities" or "junk bonds." The Funds may
invest in these securities. 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, these securities may be subject to greater
levels of interest rate, credit and liquidity risk. These securities typically
entail greater potential price volatility and may be less liquid than
higher-rated securities. They may be regarded as predominately speculative with
respect to the issuer's continuing ability to meet principal and interest
payments and may also be more susceptible to real or perceived adverse economic
and competitive industry conditions than higher-rated securities.

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 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 the party arranging
the loan.

Short Sales

Each Fund may make short sales as part of its overall portfolio management
strategies or to offset a potential decline in the 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. A Fund may only enter into short selling
transactions if the security sold short is held in the Fund's portfolio or if
the Fund has the right to acquire the security without the payment of further
consideration. 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.

When-Issued, Delayed Delivery and Forward Commitment Transactions

Each Fund may purchase securities which it is eligible to purchase on a
when-issued basis, may purchase and sell such securities for delayed delivery
and may make contracts to purchase such securities for a fixed price at a future
date beyond normal settlement time (forward commitments). When-issued
transactions, delayed delivery purchases and forward commitments involve a risk
of loss if the value of the securities declines prior to the settlement date.
This risk is in addition to the risk that the Fund's other assets will decline
in value. Therefore, these transactions may result in a form of leverage and

                                       43
<PAGE>

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 Agreements

Each Fund may enter into repurchase agreements, in which the Fund purchases a
security from a bank or broker-dealer that 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. Those
Funds whose investment objectives do not include the earning of income will
invest in repurchase agreements only as a cash management technique with respect
to that portion of its portfolio maintained in cash. Repurchase agreements
maturing in more than seven days are considered illiquid securities.

Reverse Repurchase Agreements and Other Borrowings

Each Fund may enter into reverse repurchase agreements, subject to the Fund's
limitations on borrowings. A reverse repurchase agreement involves the sale of a
security by a Fund and its agreement to repurchase the instrument at a specified
time and price, and may be considered a form of borrowing for some purposes. A
Fund will segregate assets determined to be liquid by PIMCO Advisors or a
Sub-Adviser in accordance with procedures established by the Board of Trustees
to cover its obligations under reverse repurchase agreements. 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 and other forms of borrowings may
create leveraging risk for a Fund.

Illiquid Securities

Each Fund may invest in securities that are illiquid so long as not more than
15% of the value of the Fund's net assets (taken at market value at the time of
investment) would be invested in such 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 held by the Fund, 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. Please
see "Investment Objectives and Policies" in the Statement of Additional
Information for a listing of various securities that are generally considered to
be illiquid for these purposes. 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 in Other Investment Companies

The New Asia, Europe Growth, Select World and Emerging Markets Funds may each
invest up to [10%] of their assets in securities of other investment companies,
such as closed-end management investment companies, or in pooled accounts or
other investment vehicles which invest in foreign markets. The Healthcare
Innovation, Internet Innovation, Small-Cap Technology, Telecom Innovation and
Electronics Innovation Funds may invest up to 5% of their assets in such
securities. 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.

Portfolio Turnover

The length of time a Fund has held a particular security is not 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 active and frequent
trading of portfolio securities to achieve its investment objective and
principal investment strategies, 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

                                       44
<PAGE>

are taxed at ordinary income tax rates when distributed to shareholders who are
individuals). The trading costs and tax effects associated with portfolio
turnover may adversely affect a Fund's performance.

Changes in Investment Objectives and Policies

The investment objective of each Fund described in this Prospectus may be
changed by the Board of Trustees without shareholder approval. Unless otherwise
stated in the Statement of Additional Information, all investment policies of
the Funds may be changed by the Board of Trustees without shareholder approval.
If there is a change in a Fund's investment objective or policies, including a
change approved by shareholder vote, shareholders should consider whether the
Fund remains an appropriate investment in light of their then current financial
position and needs.

New Funds

In addition to the risks described under "Summary of Principal Risks" above and
in this section, the Funds are newly formed and therefore have no history upon
which investors can evaluate their likely performance. Also, it is possible that
a Fund may invest in securities offered in initial public offerings and other
types of transactions (such as private placements) which, because of the Fund's
size, may have a disproportionate impact on the Fund's performance results. The
Funds would not necessarily have achieved the same performance results if their
aggregate net assets had been greater.

Percentage Investment Limitations

Unless otherwise stated, all percentage limitations on Fund investments listed
in this Prospectus will apply at the time of investment. A Fund would not
violate these limitations unless an excess or deficiency occurs or exists
immediately after and as a result of an investment.

Other Investments and Techniques

The Funds may invest in other types of securities and use a variety of
investment techniques and strategies which are not described in this Prospectus.
These securities and techniques may subject the Funds to additional risks.
Please see the Statement of Additional Information for additional information
about the securities and investment techniques described in this Prospectus and
about additional securities and techniques that may be used by the Funds.

</TABLE>

         The Fund seeks to achieve its investment objective by normally
investing at least 65% of its assets in common stocks of companies principally
engaged in the design, manufacture or sale of new, creative or different, or
"innovative," products or services used for or in connection with healthcare or
medicine. These companies may (but are not required to) include, for example,
pharmaceutical companies, companies involved in biotechnology, medical
diagnostic, biochemical or other healthcare research and development, companies
involved in the operation of healthcare facilities, and other companies involved
in the design, manufacture or sale of healthcare-related products or services
such as medical, dental and optical products, hardware or services. Except as
indicated above, the Fund is not required to invest exclusively in a particular
business sector or industry.

         The portfolio manager selects stocks for the Fund using a "growth"
style. The portfolio manager seeks to identify health care-related companies
with well-defined "wealth creating" characteristics, including superior earnings
growth (relative to companies in the same industry or the market as a whole),
high profitability and consistent, predictable earnings. In addition, through
fundamental research, the portfolio manager seeks to identify companies that are
gaining market share, have superior management and possess a sustainable
competitive advantage, such as superior or innovative products, personnel and
distribution systems. The Fund looks to sell a stock when the portfolio manager
believes that earnings or market sentiment are disappointing, if the company
does not meet or exceed consensus estimates on revenues and/or earnings or if an
alternative investment is more attractive.

         Although the Fund invests principally in common stocks, the Fund may
also invest in other types of equity securities, including preferred stocks and
convertible securities. The Fund may invest to a significant degree in the
securities of smaller-capitalization companies and in securities issued in
initial public offerings ("IPOs"). The Fund may invest up to 15% of its assets
in foreign securities, except that it may invest without limit in American
Depository Receipts.

         In response to unfavorable market and other conditions, the Fund may
make temporary investments of some or all of its assets in high-quality fixed
income securities. This would be inconsistent with the Fund's investment
objective and principal strategies.

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

                            the shares are held, pay more than the economic

                            the aggregate to the Fund's Class A, B and C shares
                            in excess of $2.5 billion, and [0.04%] representing
                            the Fund's organizational expenses as attributed to
                            the class ("Organizational Expenses").

                            an amount that, in essence, is equal to the Fund's
                            Organizational Expenses attributed to the class.
                            Because the Organizational Expenses will all be
                            accounted for in the Fund's initial fiscal year, the
                            Fund's reasonable expectation is that the relevant
                            conditions will not continue after the Fund's fiscal
                            year ending June 30, 2001.

                     Examples. The Examples are intended to help you compare the
                     cost of investing in Class A, B or C 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 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.(1)

</TABLE>

       The Fund seeks to achieve its investment objective by normally investing
at least 65% of its assets in common stocks of companies that derive at least
50% of their revenues, expenses or profits from the research, design,
development, manufacturing or distribution of new, creative or different, or
"innovative," products, processes or services for use with Internet- or
Internet-related businesses. Some examples of these companies may (but are not
required to) include, for example, providers of broad-band Internet access, web
site content, Internet software and electronic commerce. Except as indicated
above, the Fund is not required to invest exclusively in a particular business
sector or industry.

       The portfolio manager selects stocks for the Fund using a "growth" style.
The portfolio manager seeks to identify Internet-related companies with
well-defined "wealth creating" characteristics, including superior earnings
growth (relative to companies in the same industry or the market as a whole),
high profitability and consistent, predictable earnings. In addition, through
fundamental research, the portfolio manager seeks to identify companies that are
gaining market share, have superior management and possess a sustainable
competitive advantage, such as superior or innovative products, personnel and
distribution systems. The Fund looks to sell a stock when the portfolio manager
believes that earnings or market sentiment are disappointing, if the company
does not meet or exceed consensus estimates on revenues and/or earnings or if an
alternative investment is more attractive.

       Although the Fund invests principally in common stocks, the Fund may also
invest in other types of equity securities, including preferred stocks and
convertible securities. The Fund may invest to a significant degree in the
securities of smaller-capitalization companies and in securities issued in
initial public offerings ("IPOs"). The Fund may invest up to 15% of its assets
in foreign securities, except that it may invest without limit in American
Depository Receipts.

       In response to unfavorable market and other conditions, the Fund may make
temporary investments of some or all of its assets in high-quality fixed income
securities. This would be inconsistent with the Fund's investment objective and
principal strategies.

                  could adversely affect its net asset value, yield and total

       The Fund seeks to achieve its investment objective by normally investing
at least 65% of its assets in common stocks of technology and technology-related
companies with market capitalizations of between $100 million and $2 billion at
the time of investment. The Fund identifies its investment universe of
technology-related companies primarily by reference to classifications made by
independent firms, such as Standard & Poor's (for example, companies classified
as "Information Technology" companies), and by identifying companies that derive
a substantial portion of their revenues from the manufacture, sale and/or
service of technological products. Except as indicated above, the Fund is not
required to invest exclusively in a particular business sector or industry.


       The portfolio manager selects stocks for the Fund using a "growth" style.
The portfolio manager seeks to identify companies with well-defined "wealth
creating" characteristics, including superior earnings growth (relative to
companies in the same industry or the market as a whole), high profitability and
consistent, predictable earnings. In addition, through fundamental research, the
portfolio manager seeks to identify companies that are gaining market share,
have superior management and possess a sustainable competitive advantage, such
as superior or innovative products, personnel and distribution systems. The Fund
looks to sell a stock when the portfolio manager believes that earnings or
market sentiment are disappointing, if the company does not meet or exceed
consensus estimates on revenues and/or earnings or if an alternative investment
is more attractive.

       Although the Fund invests principally in common stocks, the Fund may also
invest to a significant degree in the securities of smaller-capitalization
companies and in other types of equity securities, including preferred stocks
and convertible securities. The Fund may invest in securities issued in initial
public offerings ("IPOs"). The Fund may invest up to 15% of its assets in
foreign securities, except that it may invest without limit in American
Depository Receipts.

       In response to unfavorable market and other conditions, the Fund may make
temporary investments of some or all of its assets in high-quality fixed income
securities. This would be inconsistent with the Fund's investment objective and
principal strategies.

                     could adversely affect its net asset value, yield and total

                            the aggregate to the Fund's Class A, B and C shares
                            in excess of $2.5 billion, and [0.04%] representing
                            the Fund's organizational expenses as attributed to
                            the class ("Organizational Expenses").
                     (3)    Net Expenses reflects the effects of a contractual
                            agreement by PIMCO Advisors to waive, reduce or
                            reimburse its Administrative Fee for each class in
                            an amount that, in essence, is equal to the Fund's
                            Organizational Expenses attributed to the class.
                            Because the Organizational Expenses will all be
                            accounted for in the Fund's initial fiscal year, the
                            Fund's reasonable expectation is that the relevant
                            conditions will not continue after the Fund's fiscal
                            year ending June 30, 2001.

                     Examples. The Examples are intended to help you compare the
                     cost of investing in Class A, B or C 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 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.(1)

       The Fund seeks to achieve its investment objective by normally investing
at least 65% of its assets in common stocks of companies principally engaged in
the development, manufacture or sale of new, creative or different, or
"innovative," communications services or communications equipment. These
companies may (but are not required to) include, for example, companies that
provide traditional local and long-distance telephone service or equipment,
companies that provide cellular, paging, local and wide area product networks or
equipment, companies that provide satellite, microwave and cable television or
equipment, and companies involved in new technologies such as fiber optics,
semiconductors and data transmission. Except as indicated above, the Fund is not
required to invest exclusively in a particular business sector or industry.

       The portfolio manager selects stocks for the Fund using a "growth" style.

       The Fund seeks to achieve its investment objective by normally investing
at least 65% of its assets in common stocks of companies principally engaged in
the development, manufacture or sale of new, creative or different, or
"innovative," electronics products and services. These companies may (but are
not required to) include, for example, companies engaged in the development,
manufacture, sale or service of electronic components, equipment vendors to
electronics manufacturers, electronic component distributors, electronic
instruments and systems vendors, and companies that provide electronics-related
services. Except as indicated above, the Fund is not required to invest
exclusively in a particular business sector or industry.

       The portfolio manager selects stocks for the Fund using a "growth" style.
The portfolio manager seeks to identify electronics-related companies with
well-defined "wealth creating" characteristics, including superior earnings
growth (relative to companies in the same industry or the market as a whole),
high profitability and consistent, predictable earnings. In addition, through
fundamental research, the portfolio manager seeks to identify companies that are
gaining market share, have superior management and possess a sustainable
competitive advantage, such as superior or innovative products, personnel and
distribution systems. The Fund looks to sell a stock when the portfolio manager
believes that earnings or market sentiment are disappointing, if the company
does not meet or exceed consensus estimates on revenues and/or earnings or if an
alternative investment is more attractive.


       Although the Fund invests principally in common stocks, the Fund may also
invest in other types of equity securities, including preferred stocks and
convertible securities. The Fund may invest to a significant degree in the
securities of smaller-capitalization companies and in securities issued in
initial public offerings ("IPOs"). The Fund may invest up to 15% of its assets
in foreign securities, except that it may invest without limit in American
Depository Receipts.

       In response to unfavorable market and other conditions, the Fund may make
temporary investments of some or all of its assets in high-quality fixed income
securities. This would be inconsistent with the Fund's investment objective and
principal strategies.

                  could adversely affect its net asset value, yield and total

       The Fund seeks to achieve its investment objective by normally investing
at least 65% of its assets in an international portfolio of common stocks and
other equity securities of companies located in Asia. The Fund will primarily
invest in securities of companies located in the Far East, including Australia,
China, Hong Kong, Indonesia, India, Malaysia, New Zealand, the Philippines,
Singapore, South Korea, Taiwan and Thailand but excluding Japan, although the
Fund will not necessarily be invested in all of these countries at any time. The
Fund may also invest in securities of foreign issuers traded on U.S. securities
markets, but will normally not invest in U.S. issuers. However, the Fund has no
other limits on geographic asset distribution and may invest in any foreign
securities market in the world. The Fund invests most of its assets in foreign
securities which trade in currencies other than the U.S. dollar and may invest
directly in foreign currencies.


       The portfolio manager selects securities for the Fund using a
research-driven "bottom-up" approach that seeks to identify companies with
above-average long-term growth prospects and attractive valuations and that
possess a sustainable competitive advantage, such as superior or innovative
products, personnel and distribution systems. In selecting stocks, the portfolio
manager analyzes a broad range of company fundamentals, such as long-term growth
prospects, price-to-earnings ratios and other valuation measures, dividend and
profit growth, balance sheet strength and return on assets. A stock's liquidity
and volatility are also considered. The portfolio manager sells stocks in order
to adjust or rebalance the Fund's portfolio and to replace companies with
weakening fundamentals.


       The Fund may utilize foreign currency exchange contracts and derivative
instruments (such as stock index futures contracts), primarily for portfolio
management and hedging purposes. The Fund may to a limited degree invest in
equity securities other than common stocks (such as equity-linked securities,
preferred stocks and convertible securities) and may invest up to 10% of its
assets in other investment companies. In response to unfavorable market and
other conditions, the Fund may make temporary investments of some or all of its
assets in foreign and domestic fixed income securities and in equity securities
of U.S. issuers. This would be inconsistent with the Fund's investment objective
and principal strategies.

                  could adversely affect its net asset value, yield and total

                            the aggregate to the Fund's Class A, B and C shares
                            in excess of $2.5 billion, and [0.04%] representing
                            the Fund's organizational expenses as attributed to
                            the class ("Organizational Expenses").
                     (3)    Net Expenses reflects the effects of a contractual
                            agreement by PIMCO Advisors to waive, reduce or
                            reimburse its Administrative Fee for each class in
                            an amount that, in essence, is equal to the Fund's
                            Organizational Expenses attributed to the class.
                            Because the Organizational Expenses will all be
                            accounted for in the Fund's initial fiscal year, the
                            Fund's reasonable expectation is that the relevant
                            conditions will not continue after the Fund's fiscal
                            year ending June 30, 2001.

                     Examples. The Examples are intended to help you compare the
                     cost of investing in Class A, B or C 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 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.(1)

                            the aggregate to the Fund's Class A, B and C shares
                            in excess of $2.5 billion, and [0.04%] representing
                            the Fund's organizational expenses as attributed to
                            the class ("Organizational Expenses").
                     (3)    Net Expenses reflects the effects of a contractual
                            agreement by PIMCO Advisors to waive, reduce or
                            reimburse its Administrative Fee for each class in
                            an amount that, in essence, is equal to the Fund's
                            Organizational Expenses attributed to the class.
                            Because the Organizational Expenses will all be
                            accounted for in the Fund's initial fiscal year, the
                            Fund's reasonable expectation is that the relevant
                            conditions will not continue after the Fund's fiscal
                            year ending June 30, 2001.

                     Examples. The Examples are intended to help you compare the
                     cost of investing in Class A, B or C 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 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.(1)

       The Fund seeks to achieve its investment objective by normally investing
at least 65% of its assets in an international portfolio of common stocks and
other equity securities of companies located throughout the world. Although the
Fund normally invests in issuers from at least five different countries,
including the United States, it may at times invest in fewer than five
countries, or even a single country. The Fund typically invests in approximately
30 to 60 stocks. Although the Fund invests primarily in developed market
countries, it may also invest in developing, or "emerging," markets. The Fund
has no other limits on geographic asset distribution and may invest in any
foreign securities market in the world. The Fund invests most of its assets in
foreign securities which trade in currencies other than the U.S. dollar and may
invest directly in foreign currencies


       The portfolio manager selects securities for the Fund using a research-
driven "bottom-up" approach that seeks to utilize the Sub-Adviser's global
research capabilities to identify companies with above-average long-term growth
prospects and attractive valuations and that possess a sustainable competitive
advantage, such as superior or innovative products, personnel and distribution
systems. The portfolio manager seeks to select those stocks with the best long-
term performance expectations, using a broad range of company fundamentals, such
as long-term growth prospects, price-to-earnings ratios and other valuation
measures, dividend and profit growth, balance sheet strength and return on
assets. The portfolio managers sell stocks in order to adjust or rebalance the
Fund's portfolio and to replace companies with weakening fundamentals.


       The Fund may utilize foreign currency exchange contracts and derivative
instruments (such as stock index futures contracts), primarily for portfolio
management and hedging purposes. The Fund may to a limited degree invest in
equity securities other than common stocks (such as equity-linked securities,
preferred stocks and convertible securities) and may invest up to 10% of its
assets in other investment companies. In response to unfavorable market and
other conditions, the Fund may make temporary investments of some or all of its
assets in foreign and domestic fixed income securities and in equity securities
of U.S. issuers. This would be inconsistent with the Fund's investment objective
and principal strategies.

                     could adversely affect its net asset value, yield and total

                            agreement by PIMCO Advisors to waive, reduce or
                            reimburse its Administrative Fee for each class in
                            an amount that, in essence, is equal to the Fund's
                            Organizational Expenses attributed to the class.
                            Because the Organizational Expenses will all be
                            accounted for in the Fund's initial fiscal year, the
                            Fund's reasonable expectation is that the relevant
                            conditions will not continue after the Fund's fiscal
                            year ending June 30, 2001.

                     Examples. The Examples are intended to help you compare the
                     cost of investing in Class A, B or C 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 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.(1)

       The Fund seeks to achieve its investment objective by normally investing
at least 65% of its assets in an international portfolio of common stocks and
other equity securities of companies located in emerging market countries within
Europe, Asia, Latin America and Africa. The Fund may also invest in securities
of foreign issuers traded on U.S. securities markets, but will normally not
invest in U.S. issuers. However, the Fund has no other limits on geographic
asset distribution and may invest in any foreign securities market in the world.
The Fund invests most of its assets in foreign securities which trade in
currencies other than the U.S. dollar and may invest directly in foreign
currencies.


       The portfolio manager selects securities for the Fund using a
research-driven "bottom-up" approach that seeks to identify companies with
above-average long-term growth prospects and attractive valuations and that
possess a sustainable competitive advantage, such as superior or innovative
products, personnel and distribution systems. In selecting stocks, the portfolio
manager analyzes a broad range of company fundamentals, such as long-term growth
prospects, price-to-earnings ratios and other valuation measures, dividend and
profit growth, balance sheet strength and return on assets. A stock's liquidity
and volatility are also considered. The portfolio manager sells stocks in order
to adjust or rebalance the Fund's portfolio and to replace companies with
weakening fundamentals.


       The Fund may utilize foreign currency exchange contracts and derivative
instruments (such as stock index futures contracts), primarily for portfolio
management and hedging purposes. The Fund may to a limited degree also invest in
equity securities other than common stocks (such as equity-linked securities,
preferred stocks and convertible securities) and may invest up to 10% of its
assets in other investment companies. In response to unfavorable market and
other conditions, the Fund may make temporary investments of some or all of its
assets in foreign and domestic fixed income securities and in equity securities
of U.S. issuers. This would be inconsistent with the Fund's investment objective
and principal strategies.

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 summarized 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.

Market Risk

The market price of securities owned by a Fund may go up or down, sometimes
rapidly or unpredictably. Each of the Funds normally invests most of its assets
in common stocks and/or other equity securities. A principal risk of investing
in each Fund is that the equity securities in its portfolio will decline in
value due to factors affecting equity securities markets generally or particular
industries represented in those markets. The values of equity securities 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 Risk

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

Growth Securities Risk

Each Fund emphasizes investments in equity securities of companies that its
portfolio manager believes will experience relatively rapid earnings growth. The
Funds place particular emphasis on growth securities. Growth securities
typically trade at higher multiples of current earnings than other securities.
Therefore, the values of growth securities may be more sensitive to changes in
current or expected earnings than the values of other securities.

Value Securities Risk

The Funds may invest in companies that may not be expected to experience
significant earnings growth, but whose securities its portfolio manager believes
are selling at a price lower than their true value. The New Asia, Europe Growth
and Emerging Markets Funds place particular emphasis on value securities.
Companies that issue value securities may have experienced adverse business
developments or may be subject to special risks that have caused their
securities to be out of favor. If a portfolio manager's assessment of a
company's prospects is wrong, or if the market does not recognize the value of
the company, the price of its securities may decline or may not approach the
value that the portfolio manager anticipates.


Smaller Company Risk

                                       32
<PAGE>

The general risks associated with equity securities and liquidity risk are
particularly pronounced for securities of companies with smaller market
capitalizations. These companies may have limited product lines, markets or
financial resources or they may depend on a few key employees. Securities of
smaller companies may trade less frequently and in lesser volume than more
widely held securities and their values may fluctuate more sharply than other
securities. They may also trade in the over-the-counter market or on a regional
exchange, or may otherwise have limited liquidity. The Small-Cap Technology Fund
has substantial exposure to this risk because it invests primarily in the
securities of companies with market capitalizations below $200 million. The
Healthcare Innovation, Internet Innovation, Telecom Innovation, Electronics
Innovation, New Asia, Europe Growth, Select World and Emerging Markets Funds
also have significant exposure to this risk.


IPO Risk

The Funds, particularly the Healthcare Innovation, Internet Innovation,
Small-Cap Technology, Telecom Innovation and Electronics Innovation Funds, may
purchase securities in initial public offerings (IPOs). These securities are
subject to many of the same risks of investing in companies with smaller market
capitalizations. Securities issued in IPOs have no trading history, and
information about the companies may be available for very limited periods. In
addition, the prices of securities sold in IPOs may be highly volatile. At any
particular time or from time to time a Fund may not be able to invest in
securities issued in IPOs, or invest to the extent desired, because, for
example, only a small portion of the securities being offered in an IPO may be
made available to the Fund or because under certain market conditions few
companies may issue securities in IPOs. In addition, as a Fund increases in
size, the impact of IPOs on the Fund's performance will generally decrease.

Liquidity Risk

All of the Funds are subject to liquidity risk. Liquidity risk exists when
particular investments are difficult to purchase or sell, possibly preventing a
Fund from selling such illiquid securities at an advantageous time or price.
Funds with principal investment strategies that involve securities of companies
with smaller market capitalizations, foreign securities, derivatives or
securities with substantial market and/or credit risk tend to have the greatest
exposure to liquidity risk.

Derivatives Risk

All of the Funds may use derivatives, which are financial contracts whose 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 may sometimes use derivatives 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, which increases opportunities for gain but
also involves greater risk of loss due to 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, 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. In addition, a Fund's use of
derivatives may increase or accelerate the amount of taxes payable by
shareholders. 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.

Sector Specific Risks

In addition to other risks, Funds that invest a substantial portion of their
assets in related industries (or

                                       33
<PAGE>


"sectors") may have greater risk because companies in these sectors may share
common characteristics and may react similarly to market developments. The Funds
that "concentrate" their investments in certain sectors and some of the risks of
investing in those sectors are provided below.


       Healthcare Related Risk. The Healthcare Innovation Fund concentrates its
       investments in the healthcare industry. Therefore, it is subject to risks
       particular to that industry, including rapid obsolescence of products and
       services, patent expirations, risks associated with new regulations and
       changes to existing regulations, changes in government subsidy and
       reimbursement levels, and risks associated with the government approval
       process.


       Internet Related Risk. The Internet Innovation Fund is subject to risks
       prevalent in the Internet sector, such as the risks of rapid obsolescence
       of products and services, intense competition, significant losses and/or
       limited earnings, security price volatility and limited operating
       histories, because it concentrates its investments in that sector.


       Technology Related Risk. Because the Small-Cap Technology Fund
       concentrates its investments in the technology sector, it is subject to
       risks prevalent in that sector, such as the risks of short product cycles
       and rapid obsolescence of products and services, competition from new and
       existing companies, significant losses and/or limited earnings, security
       price volatility and limited operating histories.


       Telecommunications Related Risk. The Telecom Innovation Fund concentrates
       its investments in the telecommunications industry. Therefore, it is
       subject to risks particularly affecting that industry, such as risks
       associated with government regulation of products, services and rates of
       return, new regulations and changes to existing regulations, changes to
       government subsidy levels, and increasing competition.


       Electronics Related Risk. The Electronics Innovation Fund is subject to
       risks prevalent in the electronics sector, such as the risks of short
       product cycles and rapid obsolescence of products and services, intense
       competition, significant losses and/or limited earnings, security price
       volatility and limited operating histories, because it concentrates its
       investments in that sector.

Foreign (non-U.S.) Investment Risk

A Fund that invests in foreign securities, and particularly the New Asia, Europe
Growth, Select World and Emerging Markets Funds, may experience more rapid and
extreme changes in value than Funds that invest exclusively in securities of
U.S. issuers or securities that trade exclusively in U.S. markets. The
securities markets of many foreign countries are relatively small, with a
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. To the extent that a Fund, such as the
New Asia, Europe Growth, Select World and Emerging Markets Funds, invests a
significant portion of its assets in a narrowly defined area such as Europe,
Asia or South America, the Fund will generally have more exposure to regional
economic risks associated with foreign investments. Adverse conditions in
certain regions (such as Southeast Asia) can also adversely affect securities of
other countries whose economies appear to be unrelated. In addition, special
U.S. tax considerations may apply to a Fund's investment in foreign securities.

Emerging Markets Risk

                                       34
<PAGE>

Foreign investment risk may be particularly high to the extent that a Fund
invests in emerging market securities of issuers based 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. The Emerging Markets Fund is
particularly susceptible to these risks because it invests principally in
companies located in emerging markets countries. The New Asia and Select World
Funds also have substantial exposure to these risks because these Funds may
invest significant portions of their assets in emerging market securities. In
addition, the risks associated with investing in a narrowly defined geographic
area (discussed above under "Foreign (non-U.S.) Investment Risk") are more
pronounced for the Funds that invest in emerging market countries.

Currency Risk

Funds that invest directly in foreign currencies or in securities that trade in,
and receive revenues in, foreign 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. The New Asia, Europe Growth, Select World and Emerging
Markets Funds are particularly sensitive to currency risk. 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.

Focused
Investment Risk


Focusing Fund investments in a small number of issuers, industries or foreign
currencies or regions increases risk. Funds that invest in a relatively small
number of issuers may have more risk because changes in the value of a single
security or the impact of a single economic, political or regulatory occurrence
may have a greater adverse impact on the Fund's net asset value. Some of those
issuers also may present substantial credit or other risks. The New Asia, Europe
Growth, Select World and Emerging Markets Funds may be subject to increased risk
to the extent that they focus their investments in securities denominated in a
particular foreign currency or in a narrowly defined geographic area such as
Europe, Asia or South America, because companies in those areas may share common
characteristics and react similarly to market developments. Also, the Funds may
from time to time have greater risk to the extent they invest a substantial
portion of their assets in related industries such as "financial and business
services" or "technology," which may also share common characteristics and react
similarly to market developments.

Leveraging Risk


Leverage, including borrowing, will cause the value of a Fund's shares to be
more volatile than if the Fund did not use leverage. This is because leverage
tends to exaggerate the effect of any increase or decrease in the value of a
Fund's portfolio securities. The Funds may engage in transactions or purchase
instruments that give rise to forms of leverage. Such transactions and
instruments may include, among others, the use of reverse repurchase agreements
and other borrowings, the investment of collateral from loans of portfolio
securities, or the use of when-issued, delayed-delivery or forward commitment
transactions. The use of derivatives may also involve leverage. The use of
leverage may also cause a Fund to liquidate portfolio positions when it would
not be advantageous to do so in order to satisfy its obligations or to meet
segregation requirements.

Interest Rate Risk

To the extent that Funds purchase fixed income securities for investment or
defensive purposes, they will be subject to interest rate risk, a market risk
relating to investments in fixed income securities such as bonds and notes. As
interest rates rise, the value of fixed income securities in a Fund's portfolio
are likely to decrease. Securities with longer "durations" (defined below) tend
to be more sensitive to changes in interest rates,

                                       35
<PAGE>

usually making them more volatile than securities with shorter durations.
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. 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 Risk

All of the Funds are subject to credit risk. This is the risk that the issuer or
the guarantor of a fixed 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 their credit ratings.

Management Risk

Each Fund is subject to management risk because it is an actively managed
investment portfolio. PIMCO Advisors, the Sub-Advisers 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.

Management of the Funds

Investment Adviser and Administrator

PIMCO Advisors serves as the investment adviser and the administrator (serving
in its capacity as administrator, the "Administrator") for the Funds. Subject to
the supervision of the Board of Trustees, PIMCO Advisors is responsible for
managing, either directly or through others selected by it, the investment
activities of the Funds and the Funds' business affairs and other administrative
matters.


PIMCO Advisors is located at 800 Newport Center Drive, Newport Beach, California
92660. Organized in 1987, PIMCO Advisors provides investment management and
advisory services to private accounts of institutional and individual clients
and to mutual funds. As of ______________, 2000, PIMCO Advisors and its
subsidiary partnerships had more than $____ billion in assets under
management.

PIMCO Advisors has retained its subsidiary PIMCO/Allianz International Advisors
LLC to manage the investments of the New Asia, Europe Growth, Select World and
Emerging Markets Funds. The PIMCO Equity Advisors division of PIMCO Advisors
manages the investments of the Healthcare Innovation, Internet Innovation,
Small-Cap Technology, Telecom Innovation and Electronics Innovation Funds (PIMCO
Equity Advisors and PIMCO/Allianz International Advisors LLC are each referred
to as a "Sub-Adviser" in this prospectus). See "Sub-Advisers" below.


PIMCO Advisors has retained its affiliate, Pacific Investment Management Company
LLC, to provide various administrative and other services required by the Funds
in its capacity as sub-administrator. PIMCO Advisors and the sub-administrator
may retain other affiliates to provide certain of these services.

Advisory Fees

Each Fund pays PIMCO Advisors fees in return for providing or arranging for the
provision of investment advisory services. In the case of Funds for which PIMCO
Advisors has retained PIMCO/Allianz International Advisors LLC, PIMCO Advisors
(and not the Fund) pays a portion of the advisory fees it receives to the
Sub-Adviser in return for its services.

The Funds will pay monthly advisory fees to PIMCO Advisors at the following
annual rates (stated as a percentage of the average daily net assets of each
Fund taken separately):


Fund                                                         Advisory Fees

Healthcare Innovation and Telecom Innovation Funds               0.70%

Europe Growth and Select World Funds                             0.75%

Internet Innovation, Small-Cap Technology and                    0.80%
Electronics Innovation Funds

New Asia and Emerging Markets Funds                              1.00%

                                       37
<PAGE>


Each Fund pays for the administrative services it requires under a fee structure
which is essentially fixed. Institutional and Administrative Class shareholders
of each Fund pay an administrative fee to PIMCO Advisors, computed as a
percentage of the Fund's assets attributable in the aggregate to those classes
of shares. PIMCO Advisors, in turn, provides or procures administrative services
for Institutional and Administrative Class shareholders and also bears the costs
of most third-party services required by the Funds, including audit, custodial,
portfolio accounting, legal, transfer agency and printing costs. The Funds do
bear other expenses which are not covered under the administrative fee which may
vary and affect the total level of expenses paid by Institutional and
Administrative Class shareholders, such as brokerage fees, commissions and other
transaction expenses, costs of borrowing money, including interest expenses, and
fees and expenses of the Trust's disinterested Trustees.

Class A, B and C shareholders of the Funds will pay PIMCO Advisors monthly
administrative fees at the following annual rates (stated as a percentage of the
average daily net assets attributable in the aggregate to the Fund's Class A,
Class B and Class C shares):

Fund                                                       Administrative Fees*

Healthcare Innovation, Internet Innovation, Small-Cap             0.50%
Technology, Telecom Innovation and Electronics
Innovation Funds

New Asia, Europe Growth, Select World and Emerging                0.70%
Markets Funds

* The Administrative Fee rate for each Fund is subject to a reduction of 0.05%
  per year on average daily net assets attributable in the aggregate to the
  Fund's Class A, B and C shares in excess of $2.5 billion.

Sub-Advisers

Each Sub-Adviser has full investment discretion and makes all determinations
with respect to the investment of a Fund's assets. The following provides
summary information about each Sub-Adviser, including the Fund(s) it manages.

Adviser/Sub-Adviser
Relationship

                     Shareholders of each Fund have approved a proposal
                     permitting PIMCO Advisors to enter into new or amended sub-
                     advisory agreements with one or more sub-advisers with
                     respect to each Fund without obtaining shareholder approval
                     of such agreements, subject to the conditions of an
                     exemptive order that has been granted by the Securities and
                     Exchange Commission. One of the conditions requires the
                     Board of Trustees to approve any such agreement. In
                     addition, the exemptive order prohibits PIMCO Advisors from
                     entering into sub-advisory agreements with affiliates of
                     PIMCO Advisors without shareholder approval, unless those
                     affiliates are substantially wholly-owned by PIMCO
                     Advisors. PIMCO Advisors has the ultimate responsibility to
                     oversee the Sub-Advisers and to recommend their hiring,
                     termination and replacement.

Distributor          The Trust's Distributor is PIMCO Funds Distributors LLC, 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.



Investment Options -- Class A, B and C Shares

The Trust offers investors Class A, Class B and Class C shares of each Fund in
this Prospectus. Each class of shares is subject to different types and levels
of sales charges than the other classes and bears a different level of expenses.

The class of shares that is best for you depends upon a number of factors,
including the amount and the intended length of your investment. The following
summarizes key information about each class to help you

                                       40


<PAGE>

make your investment decision, including the various expenses associated with
each class. More extensive information about the Trust's multi-class
arrangements is included in the PIMCO Funds Shareholders' Guide for Class A, B
and C Shares (the "Guide"), which is included as part of the Statement of
Additional Information and can be obtained free of charge from the Distributor.
See "How to Buy and Sell Shares--PIMCO Funds Shareholders' Guide" below.

Class A Shares

 . You pay an initial sales charge of up to 5.50% when you buy Class A shares.
The sales charge is deducted from your investment so that not all of your
purchase payment is invested.

 . You may be eligible for a reduction or a complete waiver of the initial sales
charge under a number of circumstances. For example, you normally pay no sales
charge if you purchase $1,000,000 or more of Class A shares. Please see the
Guide for details.

 . Class A shares are subject to lower 12b-1 fees than Class B or Class C shares.
Therefore, Class A shareholders generally pay lower annual expenses and receive
higher dividends than Class B or Class C shareholders.

 . You normally pay no contingent deferred sales charge ("CDSC") when you redeem
Class A shares, although you may pay a 1% CDSC if you purchase $1,000,000 or
more of Class A shares (and therefore pay no initial sales charge) and then
redeem the shares during the first 18 months after your initial purchase. The
Class A CDSC is waived for certain categories of investors and does not apply if
you are otherwise eligible to purchase Class A shares without a sales charge.
Please see the Guide for details.

Class B Shares

 . You do not pay an initial sales charge when you buy Class B shares. The full
amount of your purchase payment is invested initially.

 . You normally pay a CDSC of up to 5% if you redeem Class B shares during the
first six years after your initial purchase. The amount of the CDSC declines the
longer you hold your Class B shares. You pay no CDSC if you redeem during the
seventh year and thereafter. The Class B CDSC is waived for certain categories
of investors. Please see the Guide for details.

 . Class B shares are subject to higher 12b-1 fees than Class A shares for the
first seven years they are held. During this time, Class B shareholders normally
pay higher annual expenses and receive lower dividends than Class A
shareholders.

 . Class B shares automatically convert into Class A shares after they have been
held for seven years. After the conversion takes place, the shares are subject
to the lower 12b-1 fees paid by Class A shares.

Class C Shares

 . You do not pay an initial sales charge when you buy Class C shares. The full
amount of your purchase payment is invested initially.

 . You normally pay a CDSC of 1% if you redeem Class C shares during the first
year after your initial purchase. The Class C CDSC is waived for certain
categories of investors. Please see the Guide for details.

 . Class C shares are subject to higher 12b-1 fees than Class A shares.
Therefore, Class C shareholders normally pay higher annual expenses and receive
lower dividends than Class A shareholders.

                                       41
<PAGE>

 . Class C shares do not convert into any other class of shares. Because Class B
shares convert into Class A shares after seven years, Class C shares will
normally be subject to higher expenses and will pay lower dividends than Class B
shares if the shares are held for more than seven years.

The following provides additional information about the sales charges and other
expenses associated with Class A, Class B and Class C shares.


Initial Sales Charges -- Class A Shares

Unless you are eligible for a waiver, the public offering price you pay when you
buy Class A shares of the Funds is the net asset value ("NAV") of the shares
plus an initial sales charge. The initial sales charge varies depending upon the
size of your purchase, as set forth below. No sales charge is imposed where
Class A shares are issued to you pursuant to the automatic reinvestment of
income dividends or capital gains distributions.

CDSCs on Class A Shares

                                       42
<PAGE>

Unless a waiver applies, investors who purchase $1,000,000 or more of Class A
shares (and, thus, pay no initial sales charge) will be subject to a 1% CDSC if
the shares are redeemed within 18 months of their purchase. The Class A CDSC
does not apply if you are otherwise eligible to purchase Class A shares without
an initial sales charge or if you are eligible for a waiver of the CDSC. See
"Reductions and Waivers of Initial Sales Charges and CDSCs" below.


How CDSCs are Calculated

A CDSC is imposed on redemptions of Class B and Class C shares (and where
applicable, Class A shares) on the amount of the redemption which causes the
current value of your account for the particular class of shares of a Fund to
fall below the total dollar amount of your purchase payments subject to the
CDSC. However, no CDSC is imposed if the shares redeemed have been acquired
through the reinvestment of dividends or capital gains distributions or if the
amount redeemed is derived from increases in the value of your account above the
amount of the purchase payments subject to the CDSC. CDSCs are deducted from the
proceeds of your redemption, not from amounts remaining in your account. In
determining whether a CDSC is payable, it is assumed that the purchase payment
from which the redemption is made is the earliest purchase payment for the
particular class of shares in your account (from which a redemption or exchange
has not already been effected).

For instance, the following example illustrates the operation of the Class B
CDSC:

Assume that an individual opens an account and makes a purchase payment of
$10,000 for Class B shares of a Fund and that six months later the value of the
investor's account for that Fund has grown through investment performance and
reinvestment of distributions to $11,000. The investor then may redeem up to
$1,000 from that Fund ($11,000 minus $10,000) without incurring a CDSC. If the
investor should redeem $3,000, a CDSC would be imposed on $2,000 of the
redemption (the amount by which the investor's account for the Fund was reduced
below the amount of the purchase payment). At the rate of 5%, the Class B CDSC
would be $100.

In determining whether an amount is available for redemption without incurring a
CDSC, the purchase payments made for all shares of a particular class of a Fund
in the shareholder's account are aggregated, and the current value of all such
shares is aggregated.

Reductions and Waivers of Initial Sales Charges and CDSCs

The initial sales charges on Class A shares and the CDSCs on Class A, Class B
and Class C shares may be reduced or waived under certain purchase arrangements
and for certain categories of investors. Please see the Guide for details. The
Guide is available free of charge from the Distributor. See "How to Buy and Sell
Shares--PIMCO Funds Shareholders' Guide" below.


Distribution and Servicing (12b-1) Plans

The Funds pay fees to the Distributor on an ongoing basis as compensation for
the services the Distributor renders and the expenses it bears in connection
with the sale and distribution of Fund shares ("distribution fees") and/or in
connection with personal services rendered to Fund shareholders and the
maintenance of shareholder accounts ("servicing fees"). These payments are made
pursuant to Distribution and Servicing Plans ("12b-1 Plans") adopted by each
Fund pursuant to Rule 12b-1 under the Investment Company Act of 1940.

There is a separate 12b-1 Plan for each class of shares offered in this
Prospectus. Class A shares pay only servicing fees. Class B and Class C shares
pay both distribution and servicing fees. The following lists the maximum annual
rates at which the distribution and/or servicing fees may be paid under each
12b-1 Plan

                                       43
<PAGE>

(calculated as a percentage of each Fund's average daily net assets attributable
to the particular class of shares):


                                 Servicing      Distribution
All Funds                        Fee            Fee

Class A                          0.25%          None
Class B                          0.25%          0.75%
Class C                          0.25%          0.75%



Because 12b-1 fees are paid out of a Fund's assets on an ongoing basis, over
time these fees will increase the cost of your investment and may cost you more
than sales charges which are deducted at the time of investment. Therefore,
although Class B and Class C shares do not pay initial sales charges, the
distribution fees payable on Class B and Class C shares may, over time, cost you
more than the initial sales charge imposed on Class A shares. Also, because
Class B shares convert into Class A shares after they have been held for seven
years and are not subject to distribution fees after the conversion, an
investment in Class C shares may cost you more over time than an investment in
Class B shares.

How Fund Shares Are Priced

The net asset value ("NAV") of a Fund's Class A, Class B and Class C 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 the 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 quotes are not readily available may be valued, pursuant
to guidelines established by the Board of Trustees, with reference to other
securities or 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. In particular, calculation of the NAV of the New Asia, Europe Growth,
Select World and Emerging Markets Funds may not take place contemporaneously
with the determination of the prices of foreign securities used in NAV
calculations.

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 their 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.

                                       44
<PAGE>


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 or persons acting at their direction
pursuant to procedures approved by the Board of Trustees. Fair valuation may
also be used by the Board of Trustees if extraordinary events occur after the
close of the relevant market but prior to the NYSE Close.

How to Buy and Sell Shares

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

PIMCO Funds Shareholders' Guide

More detailed information about the Trust's purchase, sale and exchange
arrangements for Fund shares is provided in the PIMCO Funds Shareholders' Guide,
which is included in the Statement of Additional Information and can be obtained
free of charge from the Distributor by written request or by calling
1-800-426-0107. The Guide provides technical information about the basic
arrangements described below and also describes special purchase, sale and
exchange features and programs offered by the Trust, including:

 . Automated telephone and wire transfer procedures

 . Automatic purchase, exchange and withdrawal programs

 . Programs that establish a link from your Fund account to your bank account

 . Special arrangements for tax-qualified retirement plans

 . Investment programs which allow you to reduce or eliminate the initial sales
  charges on Class A shares

 . Categories of investors that are eligible for waivers or reductions of initial
  sales charges and CDSCs

Calculation of Share Price and Redemption Payments

When you buy shares of the Funds, you pay a price equal to the NAV of the
shares, plus any applicable sales charge. When you sell (redeem) shares, you
receive an amount equal to the NAV of the shares, minus any applicable CDSC.
NAVs are determined at the close of regular trading (normally, 4:00 p.m.,
Eastern time) on the New York Stock Exchange on each day the New York Stock
Exchange is open. See "How Fund Shares Are Priced" above 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. There are certain
exceptions where an order is received by a broker or dealer prior to the close
of regular trading on the New York Stock Exchange and then transmitted to the
Distributor after the NAV has been calculated for that day (in which case the
order may be processed at that day's NAV). Please see the Guide for details.

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
(at the succeeding day's NAV).


Buying Shares

You can buy Class A, Class B or Class C shares of the Funds in the following
ways:

 . Through your broker, dealer or other financial intermediary. Your broker,
dealer or other intermediary may establish higher minimum investment
requirements than the Trust and may also independently charge you transaction
fees and additional amounts (which may vary) in return for its services, which
will reduce your

                                       46
<PAGE>

return. Shares you purchase through your broker, dealer or other intermediary
will normally be held in your account with that firm.

 . Directly from the Trust. To make direct investments, you must open an account
with the Distributor and send payment for your shares either by mail or through
a variety of other purchase options and plans offered by the Trust.

If you wish to invest directly by mail, please send a check payable to PIMCO
Funds Distributors LLC, along with a completed application form to:

PIMCO Funds Distributors LLC
P.O. Box 9688
Providence, RI 02940-0926

The Trust accepts all purchases by mail subject to collection of checks at full
value and conversion into federal funds. You may make subsequent purchases by
mailing a check to the address above with a letter describing the investment or
with the additional investment portion of a confirmation statement. Checks for
subsequent purchases should be payable to PIMCO Funds Distributors LLC and
should clearly indicate your account number. Please call the Distributor at
1-800-426-0107 if you have any questions regarding purchases by mail.

The Guide describes a number of additional ways you can make direct investments,
including through the PIMCO Funds Auto-Invest and PIMCO Funds Fund Link
programs. You can obtain a Guide free of charge from the Distributor by written
request or by calling 1-800-426-0107. See "PIMCO Funds Shareholders' Guide"
above.

The Distributor, in its sole discretion, may accept or reject any order for
purchase of Fund shares. No share certificates will be issued unless
specifically requested in writing.

Investment Minimums

The following investment minimums apply for purchases of Class A, Class B and
Class C shares.


                Initial Investment                Subsequent Investments
                ------------------                ----------------------
                 $2,500 per Fund                      $100 per Fund


Lower minimums may apply for certain categories of investors, including certain
tax-qualified retirement plans, and for special investment programs and plans
offered by the Trust, such as the PIMCO Funds Auto-Invest and PIMCO Funds Fund
Link programs. Please see the Guide for details.


Small Account Fee

Because of the disproportionately high costs of servicing accounts with low
balances, if you have a direct account with the Distributor, you will be charged
a fee at the annual rate of $16 if your account balance for any Fund falls below
a minimum level of $2,500, except for Uniform Gift to Minors, IRA, Roth IRA and
Auto-Invest accounts for which the limit is $1,000. The fee also applies to
employer-sponsored retirement plan accounts, Money Purchase and/or Profit
Sharing plans, 401(k) plans, 403(b)(7) custodial accounts, SIMPLE IRAs, SEPs and
SAR/SEPs. (A separate custodial fee may apply to IRAs, Roth IRAs and other
retirement accounts.) However, you will not be charged this fee if the aggregate
value of all of your PIMCO Funds accounts is at least $50,000. Any applicable
small account fee will be deducted automatically from your below-minimum Fund
account in quarterly installments and paid to the Administrator. Each Fund
account will

                                       47
<PAGE>

normally be valued, and any deduction taken, during the last five business days
of each calendar quarter. Lower minimum balance requirements and waivers of the
small account fee apply for certain categories of investors. Please see the
Guide for details.

Minimum Account Size

Due to the relatively high cost to the Funds of maintaining small accounts, you
are asked to maintain an account balance in each Fund in which you invest of at
least the minimum investment necessary to open the particular type of account.
If your balance for any Fund remains below the minimum for three months or
longer, the Administrator has the right (except in the case of employer-
sponsored retirement accounts) to redeem your remaining shares and close that
Fund account after giving you 60 days to increase your balance. Your Fund
account will not be liquidated if the reduction in size is due solely to a
decline in market value of your Fund shares or if the aggregate value of all
your PIMCO Funds accounts exceeds $50,000.

Exchanging Shares

Except as provided below and/or in the applicable Funds' or series'
prospectus(es), you may exchange your Class A, Class B or Class C shares of any
Fund for the same Class of shares of any other Fund or of another series of the
Trust or PIMCO Funds: Pacific Investment Management Series. 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. Exchanges are subject to the $2,500 minimum initial
purchase requirements for each Fund, except with respect to tax-qualified
programs and exchanges effected through the PIMCO Funds Auto-Exchange plan. In
addition, an exchange is generally a taxable event which will generate capital
gains or losses, and special rules may apply in computing tax basis when
determining gain or loss. If you maintain your account with the Distributor, you
may exchange shares by completing a written exchange request and sending it to
PIMCO Funds Distributors LLC, P.O. Box 9688, Providence, RI 02940-0926. You can
get an exchange form by calling the Distributor at 1-800-426-0107.

The Trust reserves the right to refuse exchange purchases if, in the judgment of
PIMCO Advisors, 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 Advisors 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 PIMCO 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 the Securities and Exchange Commission, the Trust will give you 60
days' advance notice if it exercises its right to terminate or materially modify
the exchange privilege with respect to Class A, B and C shares.

The Guide provides more detailed information about the exchange privilege,
including the procedures you must follow and additional exchange options. You
can obtain a Guide free of charge from the Distributor by written request or by
calling 1-800-426-0107. See "PIMCO Funds Shareholders' Guide" above.

Selling Shares

You can sell (redeem) Class A, Class B or Class C shares of the Funds in the
following ways:

 . Through your broker, dealer or other financial intermediary. Your broker,
dealer or other intermediary may independently charge you transaction fees and
additional amounts (which may vary) in return for its services, which will
reduce your return.


Directly from the Trust by Written Request. To redeem shares directly from the
Trust by written request (whether or not the shares are represented by
certificates), you must send the following items to the Trust's Transfer Agent,
PFPC, Inc., P.O. Box 9688, Providence, RI 02940-0926:

(1) a written request for redemption signed by all registered owners exactly as
the account is registered on the Transfer Agent's records, including fiduciary
titles, if any, and specifying the account number and the dollar amount or
number of shares to be redeemed;

(2) for certain redemptions described below, a guarantee of all signatures on
the written request or on the share certificate or accompanying stock power, if
required, as described under "Signature Guarantee" below;

(3) any share certificates issued for any of the shares to be redeemed (see
"Certificated Shares" below); and

(4) any additional documents which may be required by the Transfer Agent for
redemption by corporations, partnerships or other organizations, executors,
administrators, trustees, custodians or guardians, or if the redemption is
requested by anyone other than the shareholder(s) of record. Transfers of shares
are subject to the same requirements.


A signature guarantee is not required for redemptions requested by and payable
to all shareholders of record for the account that is to be sent to the address
of record for that account. To avoid delay in redemption or transfer, if you
have any questions about these requirements you should contact the Transfer
Agent in writing or call 1-800-426-0107 before submitting a request. Written
redemption or transfer requests will not be honored until all required documents
in the proper form have been received by the Transfer Agent. You can not redeem
your shares by written request to the Trust if they are held in broker "street
name" accounts--you must redeem through your broker.

If the proceeds of your redemption (i) are to be paid to a person other than the
record owner, (ii) are to be sent to an address other than the address of the
account on the Transfer Agent's records, and/or (iii) are to be paid to a
corporation, partnership, trust or fiduciary, the signature(s) on the redemption
request and on the certificates, if any, or stock power must be guaranteed as
described under "Signature Guarantee" below. The Distributor may, however, waive
the signature guarantee requirement for redemptions up to $2,500 by a trustee of
a qualified retirement plan, the administrator for which has an agreement with
the Distributor.

The Guide describes a number of additional ways you can redeem your shares,
including:

   .   telephone requests to the Transfer Agent
   .   PIMCO Funds Automated Telephone System (ATS)
   .   expedited wire transfers
   .   automatic Withdrawal Plan
   .   PIMCO Funds Fund Link

Unless you specifically elect otherwise, your initial account application
permits you to redeem shares by telephone subject to certain requirements. To be
eligible for ATS, expedited wire transfer, Automatic Withdrawal Plan and Fund
Link privileges, you must specifically elect the particular option on your
account

                                       49
<PAGE>

application and satisfy certain other requirements. The Guide describes each of
these options and provides additional information about selling shares. You can
obtain a Guide free of charge from the Distributor by written request or by
calling 1-800-426-0107.

Other than an applicable CDSC, you will not pay any special fees or charges to
the Trust or the Distributor when you sell your shares. However, if you sell
your shares through your broker, dealer or other financial intermediary, that
firm may charge you a commission or other fee for processing your redemption
request.

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 payments
for more than seven days, as permitted by law.

Timing of Redemption Payments

Redemption proceeds will normally be mailed to the redeeming shareholder within
seven calendar days or, in the case of wire transfer or Fund Link redemptions,
sent to the designated bank account within one business day. Fund Link
redemptions may be received by the bank on the second or third business day. In
cases where shares have recently been purchased by personal check, redemption
proceeds may be withheld until the check has been collected, which may take up
to 15 days. To avoid such withholding, investors should purchase shares by
certified or bank check or by wire transfer. Under unusual circumstances, the
Trust may delay your redemption payments for more than seven days, as permitted
by law.

Redemptions In Kind

The Trust had agreed to redeem shares of each Fund solely in cash 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. It is highly unlikely that your shares would ever be 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.

Certificated Shares

If you are redeeming shares for which certificates have been issued, the
certificates must be mailed to or deposited with the Trust, duly endorsed or
accompanied by a duly endorsed stock power or by a written request for
redemption. Signatures must be guaranteed as described under "Signature
Guarantee" below. The Trust may request further documentation from institutions
or fiduciary accounts, such as corporations, custodians (e.g., under the Uniform
Gifts to Minors Act), executors, administrators, trustees or guardians. Your
redemption request and stock power must be signed exactly as the account is
registered, including indication of any special capacity of the registered
owner.


Signature Guarantee


When a signature guarantee is called for, you should have "Signature Guaranteed"
stamped under your signature and guaranteed by any of the following entities:
U.S. banks, foreign banks having a U.S. correspondent bank, credit unions,
savings associations, U.S. registered dealers and brokers, municipal securities
dealers and brokers, government securities dealers and brokers, national
securities exchanges, registered securities associations and clearing agencies
(each an "Eligible Guarantor Institution"). The Distributor reserves the right
to reject any signature guarantee pursuant to its written signature guarantee
standards or procedures, which permit it to reject signature guarantees from
Eligible Guarantor

                                       50
<PAGE>

Institutions that do not, based on credit guidelines, satisfy such written
standards or procedures.

Beginning January 1, 2001, when a signature guarantee is called for, a
"medallion" signature guarantee will be required. A medallion signature
guarantee may be obtained from a domestic bank or trust company, broker, dealer,
clearing agency, savings association or other financial institution which is
participating in a medallion program recognized by the Securities Transfer
Association. The three recognized medallion programs are Securities Transfer
Agents Medallion Program (STAMP), Stock Exchanges Medallion Program (SEMP) and
New York Stock Exchange, Inc. Medallion Signature Program (NYSE MSP). Signature
guarantees from financial institutions which are not participating in one of
these programs will not be accepted. Please note that financial institutions
participating in a recognized medallion program may still be ineligible to
provide a signature guarantee for transactions of greater than a specified
dollar amount.

The Trust may change the signature guarantee requirements from time to time upon
notice to shareholders, which may be given by means of a new or supplemented
Prospectus or a new or supplemented Guide. Shareholders should contact the
Distributor for additional details regarding the Funds' signature guarantee
requirements.


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, but dividends on Class B and Class C shares are expected
to be lower than dividends on Class A shares as a result of the distribution
fees applicable to Class B and Class C shares. The following shows when each
Fund intends to declare and distribute income dividends to shareholders of
record.




Fund                                               At Least Annually   Quarterly

Healthcare Innovation, Internet Innovation,                *
Small-Cap Technology, Telecom Innovation and
Electronic Innovation Funds

New Asia, Europe Growth, Select World and                  *
Emerging Markets Funds



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.

You can choose from the following distribution options:

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

 . Invest all distributions in shares of the same class of any other Fund or
another series of the Trust or PIMCO Funds: Pacific Investment Management Series
which offers that class at NAV. You must have an account existing in the Fund or
series selected for investment with the identical registered name. You must
elect this option on your account application or by a telephone request to the
Transfer Agent at 1-800-426-0107.

                                       51
<PAGE>

 . Receive all distributions in cash (either paid directly to you or credited to
your account with your broker or other financial intermediary). You must elect
this option on your account application or by a telephone request to the
Transfer Agent at 1-800-426-0107.

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.

For further information on distribution options, please contact your broker or
call the Distributor at 1-800-426-0107.


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 them 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
generally 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.

 . A Note on Foreign Investments. A Fund's investment in foreign securities may
be subject to foreign withholding taxes. In that case, the Fund's yield on those
securities would be decreased. In addition, a Fund's investments in foreign
securities or foreign currencies may increase or accelerate the Fund's
recognition of ordinary income and may affect the timing or amount of the Fund's
distributions. Shareholders of the New Asia, Europe Growth, Select World and
Emerging Markets Funds may be entitled to claim a credit or deduction with
respect to foreign taxes.

This section relates only to federal income tax consequences of investing in the
Funds; the consequences under other tax laws may differ. You should consult your
tax advisor as to the possible application of foreign, state and local income
tax laws to Fund dividends and capital distributions. Please see the Statement
of Additional Information for additional information regarding the tax aspects
of investing in the Funds.

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 identified under "Summary
Information" above. It also describes characteristics and risks of additional
securities and investment techniques that are not necessarily principal
investments or strategies but may be used by the Funds from time to time. Most
of these securities and investment techniques are discretionary, which means
that the portfolio managers 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 must rely on the professional investment judgment
and skill of PIMCO Advisors, the Sub-Advisers 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.

Fixed Income Securities and Defensive Strategies

Fixed income securities are obligations of the issuer to make payments of
principal and/or interest on future dates, and include corporate and government
bonds, notes, certificates of deposit, commercial paper, convertible securities
and mortgage-backed and other asset-backed securities.

The Healthcare Innovation, Internet Innovation, Small-Cap Technology, Telecom
Innovation, Electronics Innovation, New Asia, Europe Growth, Select World and
Emerging Markets Funds will each invest primarily in common stocks, and may also
invest in other kinds of equity securities, including preferred stocks and
securities (including fixed income securities and warrants) convertible into or
exercisable for common stocks. Each of these Funds may invest a portion of its
assets in fixed income securities. The Funds may temporarily hold up to 100% of
their assets in short-term U.S. Government securities and other money market
instruments for defensive purposes in response to unfavorable market and other
conditions. The New Asia, Europe Growth, Select World and Emerging Markets Funds
may also hold up to 100% of their assets in other domestic fixed income, foreign
fixed income and equity securities principally traded in the U.S., including
obligations issued or guaranteed by a foreign government or its agencies,
authorities or instrumentalities, corporate bonds and American Depository
Receipts, for temporary defensive purposes.

The temporary defensive strategies described in this section would be
inconsistent with the investment objective and principal investment strategies
of each of the noted Funds and may adversely affect the Fund's ability to
achieve its investment objective.


Companies With Smaller Market Capitalizations

Each of the Funds may invest in securities of companies with market
capitalizations that are small compared to other publicly traded companies. The
Small-Cap Technology Fund invests primarily in smaller companies and is
especially sensitive to the risks described below. In addition, the Healthcare
Innovation, Internet Innovation, Telecom Innovation, Electronics Innovation, New
Asia, Europe Growth, Select World and Emerging Markets Funds generally have
significant exposure to these risks.

Companies which are smaller and less well-known or seasoned than larger, more
widely held companies may offer greater opportunities for capital appreciation,
but may also involve risks different from, or greater than, risks normally
associated with larger companies. Larger companies generally have greater
financial resources, more extensive research and development, manufacturing,
marketing and service capabilities, and more stability and greater depth of
management and technical personnel than smaller companies. Smaller companies

                                       53
<PAGE>

may have limited product lines, markets or financial resources or may depend on
a small, inexperienced management group. Securities of smaller companies may
trade less frequently and in lesser volume than more widely held securities and
their values may fluctuate more abruptly or erratically than securities of
larger companies. They may also trade in the over-the-counter market or on a
regional exchange, or may otherwise have limited liquidity. These securities may
therefore be more vulnerable to adverse market developments than securities of
larger companies. Also, there may be less publicly available information about
smaller companies or less market interest in their securities as compared to
larger companies, and it may take longer for the prices of the securities to
reflect the full value of a company's earnings potential or assets.

Because securities of smaller companies may have limited liquidity, a Fund may
have difficulty establishing or closing out its positions in smaller companies
at prevailing market prices. As a result of owning large positions in this type
of security, a Fund is subject to the additional risk of possibly having to sell
portfolio securities at disadvantageous times and prices if redemptions require
the Fund to liquidate its securities positions. For these reasons, it may be
prudent for a Fund with a relatively large asset size to limit the number of
relatively small positions it holds in securities having limited liquidity in
order to minimize its exposure to such risks, to minimize transaction costs, and
to maximize the benefits of research. As a consequence, as a Fund's asset size
increases, the Fund may reduce its exposure to illiquid smaller capitalization
securities, which could adversely affect performance.

Initial Public Offerings

The Funds, particularly the Healthcare Innovation, Internet Innovation,
Small-Cap Technology, Telecom Innovation and Electronics Innovation Funds, may
purchase securities in initial public offerings (IPOs). These securities are
subject to many of the same risks of investing in companies with smaller market
capitalizations. Securities issued in IPOs have no trading history, and
information about the companies may be available for very limited periods. In
addition, the prices of securities sold in IPOs may be highly volatile. At any
particular time or from time to time a Fund may not be able to invest in
securities issued in IPOs, or invest to the extent desired, because, for
example, only a small portion of the securities being offered in an IPO may be
made available to the Fund or because under certain market conditions few
companies may issue securities in IPOs. In addition, as a Fund increases in
size, the impact of IPOs on the Fund's performance will generally decrease.

Foreign Securities

The New Asia, Europe Growth, Select World and Emerging Markets Funds normally
invest principally in securities of foreign issuers, securities traded
principally in securities markets outside the United States and/or securities
denominated in foreign currencies (together, "foreign securities"). The
Healthcare Innovation, Internet Innovation, Small-Cap Technology, Telecom
Innovation and Electronics Innovation Funds may invest up to 15% of their
respective assets in foreign securities, and may invest without limit in
ADRs.

All of the Funds may invest in American Depository Receipts ("ADRs"), European
Depository Receipts ("EDRs") and Global Depository Receipts ("GDRs"). ADRs are
dollar-denominated receipts issued generally by domestic banks and representing
the deposit with the bank of a security of a foreign issuer, and are publicly
traded on exchanges or over-the-counter in the United States. EDRs are receipts
similar to ADRs and are issued and traded in Europe. GDRs may be offered
privately in the United States and also traded in public or private markets in
other countries.

Investing in foreign securities involves special risks and considerations not
typically associated with investing in U.S. securities and shareholders should
consider carefully the substantial risks involved for Funds that invest in these
securities. 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

                                       54
<PAGE>

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, rate 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.

Emerging Market Securities

Each Fund may invest in securities of issuers based in or that trade principally
in countries with developing (or "emerging market") economies. The Emerging
Markets Fund is particularly susceptible to these risks because it invests
principally in companies located in emerging markets countries. The New Asia and
Select World Funds also have substantial exposure to these risks because these
Funds may invest significant portions of their assets in emerging market
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; and possible
repatriation of investment income and capital. In addition, foreign investors
may be required to register the proceeds of sales, and future economic or
political crises could lead to price controls, forced mergers, expropriation or
confiscatory taxation, seizure, nationalization or the 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 market 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.

   Special Risks of Investing in Russian and Other Eastern European Securities.
The Select World and Emerging Markets Funds may invest a significant portion of
their assets in securities of issuers located in Russia and in other Eastern
European countries. While investments in securities of such issuers are subject
generally to the same risks associated with investments in other emerging market
countries described above, the political, legal and operational risks of
investing in Russian and other Eastern European issuers, and of having assets
custodied within these countries, may be particularly acute. A risk of
particular note with respect to direct investment in Russian securities is the
way in which ownership of shares of companies is normally recorded. When a Fund
invests in a Russian issuer, it will normally receive a "share extract," but
that extract is not legally determinative of ownership. The official record of
ownership of a company's share is maintained by the company's share registrar.
Such share registrars are completely under the control of the issuer, and
investors are provided with few legal rights against such registrars.

Foreign Currencies

                                      55
<PAGE>

A Fund that invests directly in foreign currencies or in securities that trade
in, and receive revenues in, foreign currencies will be subject to currency
risk. The New Asia, Europe Growth, Select World and Emerging Markets Funds are
particularly sensitive to this risk.

Foreign currency exchange rates may fluctuate significantly over short periods
of time. They generally are determined by supply and demand 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. The Europe Growth Fund is especially susceptible
to risks associated with the introduction of the euro because it invests
principally in European companies, many of which are located in European
Monetary Union countries. The euro 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. The Funds may enter into forward foreign
currency exchange contracts, primarily to reduce the risks of adverse changes in
foreign exchange rates. In addition, the Funds may buy and sell foreign currency
futures contracts and options on foreign currencies and foreign currency
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.
Contracts to sell foreign currency would limit any potential gain which might be
realized by a Fund if the value of the hedged currency increases. A Fund may
enter into these contracts to hedge against foreign exchange risk arising from
the Fund's investment or anticipated investment in securities denominated in
foreign currencies. 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.

The New Asia, Europe Growth, Select World and Emerging Markets Funds may also
enter into these contracts for purposes of increasing exposure to a foreign
currency or to shift exposure to foreign currency fluctuations from one currency
to another. To the extent that it does so, a Fund will be subject to the
additional risk that the relative value of currencies will be different than
anticipated by the Fund's portfolio manager. The Funds 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. Each Fund will segregate assets determined
to be liquid by PIMCO Advisors or the Fund's Sub-Adviser 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.



Corporate Debt Securities

Corporate debt securities are subject to the risk of the issuer's inability to
meet principal and interest payments on the 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 durations tend to be more sensitive to
interest rate movements than those with shorter durations.

                                       56
<PAGE>

Convertible Securities

Each Fund may invest in convertible securities. Convertible securities are
generally preferred stocks and other securities, including fixed income
securities and warrants, that are convertible into or exercisable for common
stock at either a stated price or a stated 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. While convertible securities
generally offer lower interest or dividend yields than non-convertible fixed
income securities of similar quality, their value tends to increase as the
market value of the underlying stock increases and to decrease when the value of
the underlying stock decreases. Also, 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.

Derivatives

Each Fund may, but is not required to, use a number of 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. 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.

Examples of derivative instruments include options contracts, futures contracts,
options on futures contracts and swap agreements. The Funds may purchase and
sell (write) call and put options on securities, securities indexes and foreign
currencies. Each Fund may purchase and sell futures contracts and options
thereon with respect to securities, securities indexes and foreign currencies. 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
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.

   Leveraging 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

                                       57
<PAGE>

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 Advisors or a Sub-Adviser 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 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 (taxed at ordinary income tax rates when distributed to
shareholders who are individuals) than if the Fund had not used such
instruments.

Equity-Linked Securities

The Funds may invest up to 15% of their assets in equity-linked securities.
Equity-linked securities are privately issued securities whose investment
results are designed to correspond generally to the performance of a specified
stock index or "basket" of stocks, or sometimes a single stock. To the extent
that the Funds invest in equity-linked securities whose return corresponds to
the performance of a foreign securities index or one or more of foreign stocks,
investing in equity-linked securities will involve risks similar to the risks of
investing in foreign equity securities. See "Foreign Securities" above. In
addition, the Funds bear the risk that the issuer of an equity-linked security
may default on its obligations under the security. Equity-linked securities may
be considered illiquid and thus subject to each Fund's restrictions on
investments in illiquid securities.

Credit Ratings and Unrated Securities

The Funds may invest in securities based on their credit ratings assigned by
rating agencies such as Moody's Investors Service, Inc. ("Moody's") and Standard
and Poor's Ratings Services ("S&P"). Moody's, S&P and other rating agencies are
private services that provide ratings of the credit quality of fixed income
securities, including convertible securities. The Appendix to the Statement of
Additional Information 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 risk. 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

                                       58
<PAGE>

indicates. A Fund will not necessarily sell a security when its rating is
reduced below its rating at the time of purchase. PIMCO Advisors and the
Sub-Advisers do not rely solely on credit ratings, and develop their 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.

High Yield Securities

Securities rated lower than Baa by Moody's or lower than BBB by S&P are
sometimes referred to as "high yield securities" or "junk bonds." The Funds may
invest in high yield securities. 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, these securities may be
subject to greater levels of interest rate, credit and liquidity risk. These
securities typically entail greater potential price volatility and may be less
liquid than higher-rated securities. They may be regarded as predominantly
speculative with respect to the issuer's continuing ability to meet principal
and interest payments and may also be more susceptible to real or perceived
adverse economic and competitive industry conditions than higher-rated
securities.

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 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 the party arranging
the loan.

Short Sales

Each Fund may make short sales as part of its overall portfolio management
strategies or to offset a potential decline in the 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. A Fund may only enter into short selling
transactions if the security sold short is held in the Fund's portfolio or if
the Fund has the right to acquire the security without the payment of further
consideration. 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.

When-Issued, Delayed Delivery and Forward Commitment Transactions

Each Fund may purchase securities which it is eligible to purchase on a
when-issued basis, may purchase and sell such securities for delayed delivery
and may make contracts to purchase such securities for a fixed price at a future
date beyond normal settlement time (forward commitments). When-issued
transactions, delayed delivery purchases and forward commitments involve a risk
of loss if the value of the securities declines prior to the settlement date.
This risk is in addition to the risk that the Fund's other assets will decline
in 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

                                       59
<PAGE>

delivery of the securities is made, although a Fund may earn income on
securities it has segregated to cover these positions.

Repurchase Agreements

Each Fund may enter into repurchase agreements, in which the Fund purchases a
security from a bank or broker-dealer that 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. Those
Funds whose investment objectives do not include the earning of income will
invest in repurchase agreements only as a cash management technique with respect
to that portion of its portfolio maintained in cash. Repurchase agreements
maturing in more than seven days are considered illiquid securities.

Reverse Repurchase Agreements And Other Borrowings

Each Fund may enter into reverse repurchase agreements, subject to the Fund's
limitations on borrowings. A reverse repurchase agreement involves the sale of a
security by a Fund and its agreement to repurchase the instrument at a specified
time and price, and may be considered a form of borrowing for some purposes. A
Fund will segregate assets determined to be liquid by PIMCO Advisors or a
Sub-Adviser in accordance with procedures established by the Board of Trustees
to cover its obligations under reverse repurchase agreements. 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 and other forms of borrowings may
create leveraging risk for a Fund.

Illiquid Securities

Each Fund may invest in securities that are illiquid so long as not more than
15% of the value of the Fund's net assets (taken at market value at the time of
investment) would be invested in such 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 held by a Fund, 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. Please
see "Investment Objectives and Policies" in the Statement of Additional
Information for a listing of various securities that are generally considered to
be illiquid for these purposes. 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 in Other Investment Companies

The New Asia, Europe Growth, Select World and Emerging Markets Funds may each
invest up to 10% of their assets in securities of other investment companies,
such as closed-end management investment companies, or in pooled accounts or
other investment vehicles which invest in foreign markets. The Healthcare
Innovation, Internet Innovation, Small-Cap Technology, Telecom Innovation and
Electronics Innovation Funds may invest up to 5% of their assets in such
securities. 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.


Portfolio Turnover

                                       60
<PAGE>

The length of time a Fund has held a particular security is not 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 active and frequent
trading of portfolio securities to achieve its investment objective and
principal investment strategies, 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 taxed at ordinary income tax rates
when distributed to shareholders who are individuals). The trading costs and tax
effects associated with portfolio turnover may adversely affect a Fund's
performance.


Changes in Investment Objectives and Policies

The investment objective of each Fund described in this Prospectus may be
changed by the Board of Trustees without shareholder approval. Unless otherwise
stated in the Statement of Additional Information, all investment policies of
the Funds may be changed by the Board of Trustees without shareholder approval.
If there is a change in a Fund's investment objective or policies, including a
change approved by shareholder vote, shareholders should consider whether the
Fund remains an appropriate investment in light of their then current financial
position and needs.


New Funds

In addition to the risks described under "Summary of Principal Risks" above and
in this section, the Funds are newly formed and therefore have no history upon
which investors can evaluate their likely performance. Also, it is possible that
a Fund may invest in securities offered in initial public offerings and other
types of transactions (such as private placements) which, because of the Fund's
size, have a disproportionate impact on the Fund's performance results. The
Funds would not necessarily have achieved the same performance results if their
aggregate net assets had been greater.

<PAGE>

Percentage Investment Limitations

Unless otherwise stated, all percentage limitations on Fund investments listed
in this Prospectus will apply at the time of investment. A Fund would not
violate these limitations unless an excess or deficiency occurs or exists
immediately after and as a result of an investment.

Other Investments and Techniques

The Funds may invest in other types of securities and use a variety of
investment techniques and strategies which are not described in this Prospectus.
These securities and techniques may subject the Funds to additional risks.
Please see the Statement of Additional Information for additional information
about the securities and investment techniques described in this Prospectus and
about additional securities and techniques that may be used by the Funds.

         The Fund seeks to achieve its investment objective by normally
investing at least 65% of its assets in common stocks of companies principally
engaged in the design, manufacture or sale of new, creative or different, or
"innovative," products or services used for or in connection with healthcare or
medicine. These companies may (but are not required to) include, for example,
pharmaceutical companies, companies involved in biotechnology, medical
diagnostic, biochemical or other healthcare research and development, companies
involved in the operation of healthcare facilities, and other companies involved
in the design, manufacture or sale of healthcare-related products or services
such as medical, dental and optical products, hardware or services. Except as
indicated above, the Fund is not required to invest exclusively in a particular
business sector or industry.

         The portfolio manager selects stocks for the Fund using a "growth"
style. The portfolio manager seeks to identify health care-related companies
with well-defined "wealth creating" characteristics, including superior earnings
growth (relative to companies in the same industry or the market as a whole),
high profitability and consistent, predictable earnings. In addition, through
fundamental research, the portfolio manager seeks to identify companies that are
gaining market share, have superior management and possess a sustainable
competitive advantage, such as superior or innovative products, personnel and
distribution systems. The Fund looks to sell a stock when the portfolio manager
believes that earnings or market sentiment are disappointing, if the company
does not meet or exceed consensus estimates on revenues and/or earnings or if an
alternative investment is more attractive.


         Although the Fund invests principally in common stocks, the Fund may
also invest in other types of equity securities, including preferred stocks and
convertible securities. The Fund may invest to a significant degree in the
securities of smaller-capitalization companies and in securities issued in
initial public offerings ("IPOs"). The Fund may invest up to 15% of its assets
in foreign securities, except that it may invest without limit in American
Depository Receipts.

         In response to unfavorable market and other conditions, the Fund may
make temporary investments of some or all of its assets in high-quality fixed
income securities. This would be inconsistent with the Fund's investment
objective and principal strategies.


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

Fees and Expenses
of the Fund
                     These tables describe the fees and expenses you may pay if
                     you buy and hold Institutional Class or Administrative
                     Class shares of the Fund:

</TABLE>


                     (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 Administrative Fee paid under the
                          administration agreement may be Distribution and/or
                          Service (12b-1) Fees. The Fund will pay a total of
                          [0.85%] 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 - 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, which is based on estimated amounts
                          for the Fund's initial fiscal year, reflects the
                          portion of the Administrative Fee paid by the class
                          that is not reflected under Distribution and/or
                          Service (12b-1) Fees, and [0.04%] representing the
                          Fund's organizational expenses as attributed to the
                          class ("Organizational Expenses").


                     (3)  Net Expenses reflect the effect of a contractual
                          agreement by PIMCO Advisors to waive, reduce or
                          reimburse its Administrative Fee for Class D shares in
                          an amount that, in essence, is equal to the Fund's
                          Organizational Expenses attributed to the class.
                          Because the Organizational Expenses will all be
                          accounted for in the Fund's initial fiscal year, the
                          Fund's reasonable expectation is that the relevant
                          conditions will not continue after the Fund's fiscal
                          year ending June 30, 2001.


                     Examples. The Examples below are intended to help you
                     compare the cost of investing in Institutional Class or
                     Administrative Class 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 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.(1)

         The Fund seeks to achieve its investment objective by normally
investing at least 65% of its assets in common stocks of companies that derive
at least 50% of their revenues, expenses or profits from the research, design,
development, manufacturing or distribution of new, creative or different, or
"innovative," products, processes or services for use with Internet- or
Internet-related businesses. Some examples of these companies may (but are not
required to) include, for example, providers of broad-band Internet access, web
site content, Internet software and electronic commerce. Except as indicated
above, the Fund is not required to invest exclusively in a particular business
sector or industry.

         The portfolio manager selects stocks for the Fund using a "growth"
style. The portfolio manager seeks to identify Internet-related companies with
well-defined "wealth creating" characteristics, including superior earnings
growth (relative to companies in the same industry or the market as a whole),
high profitability and consistent, predictable earnings. In addition, through

                     (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 Administrative Fee paid
                          under the administration agreement may be Distribution
                          and/or Service (12b-1) Fees. The Fund will pay a total
                          of [0.85%] 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 - 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, which is based on estimated
                          amounts for the Fund's initial fiscal year, reflects
                          the portion of the Administrative Fee paid by the
                          class that is not reflected under Distribution and/or
                          Service (12b-1) Fees, and [0.04%] representing the
                          Fund's organizational expenses as attributed to the
                          class ("Organizational Expenses").

                          (3)  Net Expenses reflect the effect of a contractual
                          agreement by PIMCO Advisors to waive, reduce or
                          reimburse its Administrative Fee for Class D shares in
                          an amount that, in essence, is equal to the Fund's
                          Organizational Expenses attributed to the class.
                          Because the Organizational Expenses will all be
                          accounted for in the Fund's initial fiscal year, the
                          Fund's reasonable expectation is that the relevant
                          conditions will not continue after the Fund's fiscal
                          year ending June 30, 2001.

                     Examples. The Examples below are intended to help you
                     compare the cost of investing in Institutional Class or
                     Administrative Class 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 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.(1)

</TABLE>

       The Fund seeks to achieve its investment objective by normally investing
at least 65% of its assets in common stocks of technology and technology-related
companies with market capitalizations of between $100 million and $2 billion at
the time of investment. The Fund identifies its investment universe of
technology-related companies primarily by reference to classifications made by
independent firms, such as Standard & Poor's (for example, companies classified
as "Information Technology" companies), and by identifying companies that derive
a substantial portion of their revenues from the manufacture, sale and/or
service of technological products. Except as indicated above, the Fund is not
required to invest exclusively in a particular business sector or industry.

       The portfolio manager selects stocks for the Fund using a "growth" style.
The portfolio manager seeks to identify companies with well-defined "wealth
creating" characteristics, including superior earnings growth (relative to
companies in the same industry or the market as a whole), high profitability and
consistent, predictable earnings. In addition, through fundamental research, the
portfolio manager seeks to identify companies that are gaining market share,
have superior management and possess a sustainable competitive advantage, such
as superior or innovative products, personnel and distribution systems. The Fund
looks to sell a stock when the portfolio manager believes that earnings or
market sentiment are disappointing, if the company does not meet or exceed
consensus estimates on revenues and/or earnings or if an alternative investment
is more attractive.

       Although the Fund invests principally in common stocks, the Fund may also
invest to a significant degree in the securities of smaller-capitalization
companies and in other types of equity securities, including preferred stocks
and convertible securities. The Fund may invest in securities issued in initial
public offerings ("IPOs"). The Fund may invest up to 15% of its assets in
foreign securities, except that it may invest without limit in American
Depository Receipts.

       In response to unfavorable market and other conditions, the Fund may make
temporary investments of some or all of its assets in high-quality fixed income
securities. This would be inconsistent with the Fund's investment objective and
principal strategies.

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

</TABLE>


                 (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 Administrative Fee paid under the
                        administration agreement may be Distribution and/or
                        Service (12b-1) Fees. The Fund will pay a total of
                        [0.85%] 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 - 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, which is based on estimated amounts for
                        the Fund's initial fiscal year, reflects the portion of
                        the Administrative Fee paid by the class that is not
                        reflected under Distribution and/or Service (12b-1)
                        Fees, and [0.04%] representing the Fund's organizational
                        expenses as attributed to the class ("Organizational
                        Expenses").

                 (3)    Net Expenses reflect the effect of a contractual
                        agreement by PIMCO Advisors to waive, reduce or
                        reimburse its Administrative Fee for Class D shares in
                        an amount that, in essence, is equal to the Fund's
                        Organizational Expenses attributed to the class. Because
                        the Organizational Expenses will all be accounted for in
                        the Fund's initial fiscal year, the Fund's reasonable
                        expectation is that the relevant conditions will not
                        continue after the Fund's fiscal year ending June 30,
                        2001.

                 Examples. The Examples below are intended to help you compare
                 the cost of investing in Institutional Class or Administrative
                 Class 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
                 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.(1)

         The Fund seeks to achieve its investment objective by normally
investing at least 65% of its assets in common stocks of companies principally
engaged in the development, manufacture or sale of new, creative or different,
or "innovative," communications services or communications equipment. These
companies may (but are not required to) include, for example, companies that
provide traditional local and long-distance telephone service or equipment,
companies that provide cellular, paging, local and wide area product networks or
equipment, companies that provide satellite, microwave and cable television or
equipment, and companies involved in new technologies such as fiber optics,
semiconductors and data transmission. Except as indicated above, the Fund is not
required to invest exclusively in a particular business sector or industry.

         The portfolio manager selects stocks for the Fund using a "growth"
style. The portfolio manager seeks to identify telecommunications-related
companies with well-defined "wealth creating" characteristics, including
superior earnings growth (relative to companies in the same industry or the
market as a whole), high profitability and consistent, predictable earnings. In
addition, through fundamental research, the portfolio manager seeks to identify
companies that are gaining market share, have superior management and possess a
sustainable competitive advantage, such as superior or innovative products,
personnel and distribution systems. The Fund looks to sell a stock when the
portfolio manager believes that earnings or market sentiment are disappointing,
if the company does not meet or exceed consensus estimates on revenues and/or
earnings or if an alternative investment is more attractive.

         Although the Fund invests principally in common stocks, the Fund may
also invest in other types of equity securities, including preferred stocks and
convertible securities. The Fund may invest to a significant degree in the
securities of smaller-capitalization companies and in securities issued in
initial public offerings ("IPOs"). The Fund may invest up to 15% of its assets
in foreign securities, except that it may invest without limit in American
Depository Receipts.

         In response to unfavorable market and other conditions, the Fund may
make temporary investments of some or all of its assets in high-quality fixed
income securities. This would be inconsistent with the Fund's investment
objective and principal strategies.

Principal        Risks Among the principal risks of investing in the

                     (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 Administrative Fee paid
                          under the administration agreement may be Distribution
                          and/or Service (12b-1) Fees. The Fund will pay a total
                          of [0.85%] 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 - 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, which is based on estimated amounts
                          for the Fund's initial fiscal year, reflects the
                          portion of the Administrative Fee paid by the class
                          that is not reflected under Distribution and/or
                          Service (12b-1) Fees, and [0.04%] representing the
                          Fund's organizational expenses as attributed to the
                          class ("Organizational Expenses").

                     (3)  Net Expenses reflect the effect of a contractual
                          agreement by PIMCO Advisors to waive, reduce or
                          reimburse its Administrative Fee for Class D shares in
                          an amount that, in essence, is equal to the Fund's
                          Organizational Expenses attributed to the class.
                          Because the Organizational Expenses will all be
                          accounted for in the Fund's initial fiscal year, the
                          Fund's reasonable expectation is that the relevant
                          conditions will not continue after the Fund's fiscal
                          year ending June 30, 2001.

                     Examples. The Examples below are intended to help you
                     compare the cost of investing in Institutional Class or
                     Administrative Class 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 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.(1)

         The Fund seeks to achieve its investment objective by normally
investing at least 65% of its assets in common stocks of companies principally
engaged in the development, manufacture or sale of new, creative or different,
or "innovative," electronics products and services. These companies may (but are
not required to) include, for example, companies engaged in the development,
manufacture, sale or service of electronic components, equipment vendors to
electronics manufacturers, electronic component distributors, electronic
instruments and systems vendors, and companies that provide electronics-related
services. Except as indicated above, the Fund is not required to invest
exclusively in a particular business sector or industry.

         The portfolio manager selects stocks for the Fund using a "growth"
style. The portfolio manager seeks to identify electronics-related companies
with well-defined "wealth creating" characteristics, including superior earnings
growth (relative to companies in the same industry or the market as a whole),
high profitability and consistent, predictable earnings. In addition, through
fundamental research, the portfolio manager seeks to identify companies that are
gaining market share, have superior management and possess a sustainable
competitive advantage, such as superior or innovative products, personnel and
distribution systems. The Fund looks to sell a stock when the portfolio manager
believes that earnings or market sentiment are disappointing, if the company
does not meet or exceed consensus estimates on revenues and/or earnings or if an
alternative investment is more attractive.

         Although the Fund invests principally in common stocks, the Fund may
also invest in other types of equity securities, including preferred stocks and
convertible securities. The Fund may invest to a significant degree in the
securities of smaller-capitalization companies and in securities issued in
initial public offerings ("IPOs"). The Fund may invest up to 15% of its assets
in foreign securities, except that it may invest without limit in American
Depository Receipts.

         In response to unfavorable market and other conditions, the Fund may
make temporary investments of some or all of its assets in high-quality fixed
income securities. This would be inconsistent with the Fund's investment
objective and principal strategies.

         The Fund seeks to achieve its investment objective by normally
investing at least 65% of its assets in an international portfolio of common
stocks and other equity securities of companies located in Asia. The Fund will
primarily invest in securities of companies located in the Far East, including
Australia, China, Hong Kong, Indonesia, India, Malaysia, New Zealand, the
Philippines, Singapore, South Korea, Taiwan and Thailand but excluding Japan,
although the Fund will not necessarily be invested in all of these countries at
any time. The Fund may also invest in securities of foreign issuers traded on
U.S. securities markets, but will normally not invest in U.S. issuers. However,
the Fund has no other limits on geographic asset distribution and may invest in
any foreign securities market in the world. The Fund invests most of its assets
in foreign securities which trade in currencies other than the U.S. dollar and
may invest directly in foreign currencies.

         The portfolio manager selects securities for the Fund using a
research-driven "bottom-up" approach that seeks to identify companies with
above-average long-term growth prospects and attractive valuations and that
possess a sustainable competitive advantage, such as superior or innovative
products, personnel and distribution systems. In selecting stocks, the portfolio
manager analyzes a broad range of company fundamentals, such as long-term growth
prospects, price-to-earnings ratios and other valuation measures, dividend and
profit growth, balance sheet strength and return on assets. A stock's liquidity
and volatility are also considered. The portfolio manager sells stocks in order
to adjust or rebalance the Fund's portfolio and to replace companies with
weakening fundamentals.

         The Fund may utilize foreign currency exchange contracts and derivative
instruments (such as stock index futures contracts), primarily for portfolio
management and hedging purposes. The Fund may to a limited degree invest in
equity securities other than common stocks (such as equity-linked securities,
preferred stocks and convertible securities) and may invest up to 10% of its
assets in other investment companies. In response to unfavorable market and
other conditions, the Fund may make temporary investments of some or all of its
assets in foreign and domestic fixed income securities and in equity securities
of U.S. issuers. This would be inconsistent with the Fund's investment objective
and principal strategies.

</TABLE>
                     (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 Administrative Fee paid under the
                          administration agreement may be Distribution and/or
                          Service (12b-1) Fees. The Fund will pay a total of
                          [0.85%] 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 - 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, which is based on estimated amounts
                          for the Fund's initial fiscal year, reflects the
                          portion of the Administrative Fee paid by the class
                          that is not reflected under Distribution and/or
                          Service (12b-1) Fees, and [0.04%] representing the
                          Fund's organizational expenses as attributed to the
                          class ("Organizational Expenses").

                     (3)  Net Expenses reflect the effect of a contractual
                          agreement by PIMCO Advisors to waive, reduce or
                          reimburse its Administrative Fee for Class D shares in
                          an amount that, in essence, is equal to the Fund's
                          Organizational Expenses attributed to the class.
                          Because the Organizational Expenses will all be
                          accounted for in the Fund's initial fiscal year, the
                          Fund's reasonable expectation is that the relevant
                          conditions will not continue after the Fund's fiscal
                          year ending June 30, 2001.

                     Examples. The Examples below are intended to help you
                     compare the cost of investing in Institutional Class or
                     Administrative Class 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 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.(1)

                     (3)  Net Expenses reflect the effect of a contractual
                          agreement by PIMCO Advisors to waive, reduce or
                          reimburse its Administrative Fee for Class D shares in
                          an amount that, in essence, is equal to the Fund's
                          Organizational Expenses attributed to the class.
                          Because the Organizational Expenses will all be
                          accounted for in the Fund's initial fiscal year, the
                          Fund's reasonable expectation is that the relevant
                          conditions will not continue after the Fund's fiscal
                          year ending June 30, 2001.

                     Examples. The Examples below are intended to help you
                     compare the cost of investing in Institutional Class or
                     Administrative Class 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 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.(1)

</TABLE>


         The Fund seeks to achieve its investment objective by normally
investing at least 65% of its assets in an international portfolio of common
stocks and other equity securities of companies located throughout the world.
Although the Fund normally invests in issuers from at least five different
countries, including the United States, it may at times invest in fewer than
five countries, or even a single country. The Fund typically invests in
approximately 30 to 60 stocks. Although the Fund invests primarily in developed
market countries, it may also invest in developing, or "emerging," markets. The
Fund has no other limits on geographic asset distribution and may invest in any
foreign securities market in the world. The Fund invests most of its assets in
foreign securities which trade in currencies other than the U.S. dollar and may
invest directly in foreign currencies.

         The portfolio manager selects securities for the Fund using a
research-driven "bottom-up" approach that seeks to utilize the Sub-Adviser's
global research capabilities to identify companies with above-average long-term
growth prospects and attractive valuations and that possess a sustainable
competitive advantage, such as superior or innovative products, personnel and
distribution systems. The portfolio manager seeks to select those stocks with
the best long-term performance expectations, using a broad range of company
fundamentals, such as long-term growth prospects, price-to-earnings ratios and
other valuation measures, dividend and profit growth, balance sheet strength and
return on assets. The portfolio managers sell stocks in order to adjust or
rebalance the Fund's portfolio and to replace companies with weakening
fundamentals.

         The Fund may utilize foreign currency exchange contracts and derivative
instruments (such as stock index futures contracts), primarily for portfolio
management and hedging purposes. The Fund may to a limited degree invest in
equity securities other than common stocks (such as equity-linked securities,
preferred stocks and convertible securities) and may invest up to 10% of its
assets in other investment companies. In response to unfavorable market and
other conditions, the Fund may make temporary investments of some or all of its
assets in foreign and domestic fixed income securities and in equity securities
of U.S. issuers. This would be inconsistent with the Fund's investment objective
and principal strategies.

</TABLE>

                     (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 Administrative Fee paid under the
                          administration agreement may be Distribution and/or
                          Service (12b-1) Fees. The Fund will pay a total of
                          [0.85%] 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 - 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, which is based on estimated amounts
                          for the Fund's initial fiscal year, reflects the
                          portion of the Administrative Fee paid by the class
                          that is not reflected under Distribution and/or
                          Service (12b-1) Fees, and [0.04%] representing the
                          Fund's organizational expenses as attributed to the
                          class ("Organizational Expenses").

                     (3)  Net Expenses reflect the effect of a contractual
                          agreement by PIMCO Advisors to waive, reduce or
                          reimburse its Administrative Fee for Class D shares in
                          an amount that, in essence, is equal to the Fund's
                          Organizational Expenses attributed to the class.
                          Because the Organizational Expenses will all be
                          accounted for in the Fund's initial fiscal year, the
                          Fund's reasonable expectation is that the relevant
                          conditions will not continue after the Fund's fiscal
                          year ending June 30, 2001.

                     Examples. The Examples below are intended to help you
                     compare the cost of investing in Institutional Class or
                     Administrative Class 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 the Fund's
                     operating expenses remain the same. Although your actual

         The Fund seeks to achieve its investment objective by normally
investing at least 65% of its assets in an international portfolio of common
stocks and equity securities of companies located in emerging market countries
within Europe, Asia, Latin America and Africa. The Fund may also invest in
securities of foreign issuers traded on U.S. securities markets, but will
normally not invest in U.S. issuers. However, the Fund has no other limits on
geographic asset distribution and may invest in any foreign securities market in
the world. The Fund invests most of its assets in foreign securities which trade
in currencies other than the U.S. dollar and may invest directly in foreign

                     (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 Administrative Fee paid under the
                          administration agreement may be Distribution and/or
                          Service (12b-1) Fees. The Fund will pay a total of
                          [0.85%] 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 - 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, which is based on estimated amounts
                          for the Fund's initial fiscal year, reflects the
                          portion of the Administrative Fee paid by the class
                          that is not reflected under Distribution and/or
                          Service (12b-1) Fees, and [0.04%] representing the
                          Fund's organizational expenses as attributed to the
                          class ("Organizational Expenses").

                     (3)  Net Expenses reflect the effect of a contractual
                          agreement by PIMCO Advisors to waive, reduce or
                          reimburse its Administrative Fee for Class D shares in
                          an amount that, in essence, is equal to the Fund's
                          Organizational Expenses attributed to the class.
                          Because the Organizational Expenses will all be
                          accounted for in the Fund's initial fiscal year, the
                          Fund's reasonable expectation is that the relevant
                          conditions will not continue after the Fund's fiscal
                          year ending June 30, 2001.

                     Examples. The Examples below are intended to help you
                     compare the cost of investing in Institutional Class or
                     Administrative Class 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 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.(1)

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 summarized 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 each 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.

Market Risk

The market price of securities owned by a Fund may go up or down, sometimes
rapidly or unpredictably. Each of the Funds normally invests most of its assets
in common stocks and/or other equity securities. A principal risk of investing
in each Fund is that the equity securities in its portfolio will decline in
value due to factors affecting equity securities markets generally or particular
industries represented in those markets. The values of equity securities 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 Risk

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

Growth Securities Risk

Each Fund emphasizes investments in equity securities of companies that its
portfolio manager believes will experience relatively rapid earnings growth. The
Funds place particular emphasis on growth securities. Growth securities
typically trade at higher multiples of current earnings than other securities.
Therefore, the values of growth securities may be more sensitive to changes in
current or expected earnings than the values of other securities.

Value Securities Risk

The Funds may invest in companies that may not be expected to experience
significant earnings growth, but whose securities its portfolio manager believes
are selling at a price lower than their true value. The New Asia, Europe Growth
and Emerging Markets Funds place particular emphasis on value securities.
Companies that issue value securities may have experienced adverse business
developments or may be subject to special risks that have caused their
securities to be out of favor. If a portfolio manager's assessment of a
company's prospects is wrong, or if the market does not recognize the value of
the company, the price of its securities may decline or may not approach the
value that the portfolio manager anticipates.

Smaller Company Risk

The general risks associated with equity securities and liquidity risk are
particularly pronounced for securities of companies with smaller market
capitalizations. These companies may have limited product lines, markets or
financial resources or they may depend on a few key employees. Securities of
smaller companies may trade less frequently and in lesser volume than more
widely held securities and their values may fluctuate more sharply than other
securities. They may also trade in the over-the-counter market or on a regional
exchange, or may otherwise have limited liquidity. The Small-Cap Technology Fund
has substantial exposure to this risk because it invests primarily in the
securities of companies with market capitalizations below $200 million. The
Healthcare Innovation,

                                       23
<PAGE>

Internet Innovation, Telecom Innovation, Electronics Innovation, New Asia,
Europe Growth, Select World and Emerging Markets Funds also have significant
exposure to this risk because they invest substantial assets in companies with
medium-sized market capitalizations, which are smaller and generally
less-seasoned than the largest companies.


IPO Risk


The Funds, particularly the Healthcare Innovation, Internet Innovation,
Small-Cap Technology, Telecom Innovation and Electronics Innovation Funds, may
purchase securities in initial public offerings (IPOs). These securities are
subject to many of the same risks of investing in companies with smaller market
capitalizations. Securities issued in IPOs have no trading history, and
information about the companies may be available for very limited periods. In
addition, the prices of securities sold in IPOs may be highly volatile. At any
particular time or from time to time a Fund may not be able to invest in
securities issued in IPOs, or invest to the extent desired, because, for
example, only a small portion of the securities being offered in an IPO may be
made available to the Fund or because under certain market conditions few
companies may issue securities in IPOs. In addition, as a Fund increases in
size, the impact of IPOs on the Fund's performance will generally decrease.

Liquidity Risk

All of the Funds are subject to liquidity risk. Liquidity risk exists when
particular investments are difficult to purchase or sell, possibly preventing a
Fund from selling such illiquid securities at an advantageous time or price.
Funds with principal investment strategies that involve securities of companies
with smaller market capitalizations, foreign securities, derivatives or
securities with substantial market and/or credit risk tend to have the greatest
exposure to liquidity risk.

Derivatives Risk

All of the Funds may use derivatives, which are financial contracts whose 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 may sometimes use derivatives 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, which increases opportunities for gain but
also involves greater risk of loss due to 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, 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. In addition, a Fund's use of
derivatives may increase or accelerate the amount of taxes payable by
shareholders. 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.


Sector Specific Risks


In addition to other risks, Funds that invest a substantial portion of their
assets in related industries (or "sectors") may have greater risk because
companies in these sectors may share common characteristics and may react
similarly to market developments. The Funds that "concentrate" their investments
in certain sectors and some of the risks of investing in those sectors are
provided below.


         Healthcare Related Risk. The Healthcare Innovation Fund concentrates
         its investments in the healthcare industry. Therefore, it is subject to
         risks particular to that industry, including rapid obsolescence of
         products and services, patent expirations, risks associated with new
         regulations and changes to existing regulations, changes in government
         subsidy and reimbursement levels, and risks associated with the
         government approval process.

                                       24
<PAGE>


         Internet Related Risk. The Internet Innovation Fund is subject to risks
         prevalent in the Internet sector, such as the risks of rapid
         obsolescence of products and services, intense competition, significant
         losses and/or limited earnings, security price volatility and limited
         operating histories, because it concentrates its investments in that
         sector.


         Technology Related Risk. Because the Small-Cap Technology Fund
         concentrates its investments in the technology sector, it is subject to
         risks prevalent in that sector, such as the risks of short product
         cycles and rapid obsolescence of products and services, competition
         from new and existing companies, significant losses and/or limited
         earnings, security price volatility and limited operating histories.



         Telecommunications Related Risk. The Telecom Innovation Fund
         concentrates its investments in the telecommunications industry.
         Therefore, it is subject to risks particularly affecting that industry,
         such as risks associated with government regulation of products,
         services and rates of return, new regulations and changes to existing
         regulations, changes to government subsidy levels, and increasing
         competition.


         Electronics Related Risk. The Electronics Innovation Fund is subject to
         risks prevalent in the electronics sector, such as the risks of short
         product cycles and rapid obsolescence of products and services, intense
         competition, significant losses and/or limited earnings, security price
         volatility and limited operating histories, because it concentrates its
         investments in that sector.


Foreign (non-U.S.) Investment Risk

A Fund that invests in foreign securities, and particularly the New Asia, Europe
Growth, Select World and Emerging Markets Funds, may experience more rapid and
extreme changes in value than Funds that invest exclusively in securities of
U.S. issuers or securities that trade exclusively in U.S. markets. The
securities markets of many foreign countries are relatively small, with a
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. To the extent that a Fund, such as New
Asia, Europe Growth, Select World and Emerging Markets Funds, invests a
significant portion of its assets in a narrowly defined geographic area such as
Europe, Asia or South America, the Fund will generally have more exposure to
regional economic risks associated with foreign investments. Adverse conditions
in certain regions (such as Southeast Asia) can also adversely affect securities
of other countries whose economies appear to be unrelated. In addition, special
U.S. tax considerations may apply to a Fund's investment in foreign securities.

Emerging Markets Risk

Foreign investment risk may be particularly high to the extent that a Fund
invests in emerging market securities of issuers based 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. The Emerging Markets Fund is
particularly susceptible to these risks because it invests principally in
companies located in emerging markets countries. The New Asia and Select World
Funds also have substantial exposure to these risks because these Funds may
invest a significant portion of their assets in emerging market securities. In
addition, the risks associated with investing in a narrowly defined geographic
area (discussed above under "Foreign (non-U.S.) Investment Risk") are more
pronounced for the Funds that invest in emerging markets.

Currency Risk

Funds that invest directly in foreign currencies or in securities that trade in,
and receive revenues in, foreign

                                       25
<PAGE>

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. The New
Asia, Europe Growth, Select World and Emerging Markets Funds are particularly
sensitive to currency risk. 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.

Focused Investment Risk


Focusing Fund investments in a small number of issuers, industries or foreign
currencies or regions increases risk. Funds that invest in a relatively small
number of issuers may have more risk because changes in the value of a single
security or the impact of a single economic, political or regulatory occurrence
may have a greater adverse impact on the Fund's net asset value. Some of those
issuers also may present substantial credit or other risks. The New Asia, Europe
Growth, Select World and Emerging Markets Funds may be subject to increased risk
to the extent that they focus their investments in securities denominated in a
particular foreign currency or in a narrowly defined geographic area such as
Europe, Asia or South America, because companies in those areas may share common
characteristics and react similarly to market developments. Also, the Funds may
from time to time have greater risk to the extent they invest a substantial
portion of their assets in related industries such as "financial and business
services" or "technology," which may also share common characteristics and react
similarly to market developments.

Leveraging Risk


Leverage, including borrowing, will cause the value of a Fund's shares to be
more volatile than if the Fund did not use leverage. This is because leverage
tends to exaggerate the effect of any increase or decrease in the value of a
Fund's portfolio securities. The Funds may engage in transactions or purchase
instruments that give rise to forms of leverage. Such transactions and
instruments may include, among others, the use of reverse repurchase agreements
and other borrowings, the investment of collateral from loans of portfolio
securities, or the use of when-issued, delayed-delivery or forward commitment
transactions. The use of derivatives may also involve leverage. The use of
leverage may also cause a Fund to liquidate portfolio positions when it would
not be advantageous to do so in order to satisfy its obligations or to meet
segregation requirements.

Interest Rate Risk


To the extent that Funds purchase fixed income securities for investment or
defensive purposes, they will be subject to interest rate risk, a market risk
relating to investments in fixed income securities such as bonds and notes. As
interest rates rise, the value of fixed income securities in a Fund's portfolio
are likely to decrease. Securities with longer "durations" (defined below) tend
to be more sensitive to changes in interest rates, usually making them more
volatile than securities with shorter durations. 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. 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 Risk

All of the Funds are subject to credit risk. This is the risk that the issuer or
the guarantor of a fixed 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 their credit ratings.

Management Risk

Each Fund is subject to management risk because it is an actively managed
investment portfolio. PIMCO Advisors, the Sub-Advisers 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.

                                       26

Management of the Funds

Investment Adviser and Administrator

PIMCO Advisors serves as the investment adviser and the administrator (serving
in its capacity as administrator, the "Administrator") for the Funds. Subject to
the supervision of the Board of Trustees, PIMCO Advisors is responsible for
managing, either directly or through others selected by it, the investment
activities of the Funds and the Funds' business affairs and other administrative
matters.


PIMCO Advisors is located at 800 Newport Center Drive, Newport Beach, California
92660. Organized in 1987, PIMCO Advisors provides investment management and
advisory services to private accounts of institutional and individual clients
and to mutual funds. As of [ ], 2000, PIMCO Advisors and its subsidiary
partnerships had more than $[ ] billion in assets under management.

PIMCO Advisors has retained its subsidiary PIMCO/Allianz International Advisors
LLC to manage the investments of the New Asia, Europe Growth, Select World and
Emerging Markets Funds. The PIMCO Equity Advisors division of PIMCO Advisors
manages the investments of the Healthcare Innovation, Internet Innovation,
Small-Cap Technology, Telecom Innovation and Electronics Innovation Funds (PIMCO
Equity Advisors and PIMCO/Allianz International Advisors LLC are each referred
to as a "Sub-Adviser" in this prospectus). See "Sub-Advisers" below.


PIMCO Advisors has retained its affiliate, Pacific Investment Management Company
LLC, to provide various administrative and other services required by the Funds
in its capacity as sub-administrator. PIMCO Advisors and the sub-administrator
may retain other affiliates to provide certain of these services.

Advisory Fees

Each Fund pays PIMCO Advisors fees in return for providing or arranging for the
provision of investment advisory services. In the case of Funds for which PIMCO
Advisors has retained PIMCO/Allianz International Advisors LLC, PIMCO Advisors
(and not the Fund) pays a portion of the advisory fees it receives to the
Sub-Adviser in return for its services.

The Funds will pay monthly advisory fees to PIMCO Advisors at the following
annual rates (stated as a percentage of the average daily net assets of each
Fund taken separately):

Fund                                                         Advisory Fees

Healthcare Innovation and Telecom                                0.70%
Innovation Funds

Europe Growth and Select World Funds                             0.75%

Internet Innovation, Small-Cap Technology                        0.80%
and Electronics Innovation Funds

New Asia and Emerging Markets Funds                              1.00%


Administrative Fees


Each Fund pays for the administrative services it requires under a fee structure
which is essentially fixed. Institutional and Administrative Class shareholders
of each Fund pay an administrative fee to PIMCO Advisors, computed as a
percentage of the Fund's assets attributable in the aggregate to those classes
of shares. PIMCO Advisors, in turn, provides or procures administrative services
for Institutional and Administrative Class shareholders and also bears the costs
of most third-party services required by the Funds, including audit, custodial,
portfolio accounting, legal, transfer agency and printing costs. The Funds do
bear other expenses which are not covered under the administrative fee which may
vary and affect the total level of expenses paid by Institutional and
Administrative Class shareholders, such as brokerage fees, commissions and other
transaction expenses, costs of borrowing money, including interest expenses, and
fees and expenses of the Trust's disinterested Trustees.

Class D shareholders of the Funds will pay PIMCO Advisors monthly administrative
fees at the following annual rates (stated as a percentage of the average daily
net assets attributable in the aggregate to the Fund's Class D

                                       27
<PAGE>

shares):

Fund                                                       Administrative Fees

Healthcare Innovation, Internet Innovation,                     [0.50]%
Small-Cap Technology, Telecom Innovation
and Electronics Innovation Funds

New Asia, Europe Growth, Select World and                       [0.70]%
Emerging Markets Funds

12b-1 Plan for Class D Shares

The Funds' 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 1940 Act. The plan provides that 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.

Sub-Advisers

Each Sub-Adviser has full investment discretion and makes all determinations

Adviser/Sub-Adviser Relationship

Shareholders of each Fund have approved a proposal permitting PIMCO Advisors to
enter into new or amended sub-advisory agreements with one or more sub-advisers
with respect to each Fund without obtaining shareholder approval of such
agreements, subject to the conditions of an exemptive order that has been
granted by the Securities and Exchange Commission. One of the conditions
requires the Board of Trustees to approve any such agreement. In addition, the
exemptive order prohibits PIMCO Advisors from entering into sub-advisory
agreements with affiliates of PIMCO Advisors without shareholder approval,
unless those affiliates are substantially wholly-owned by PIMCO Advisors. PIMCO
Advisors has the ultimate responsibility to oversee the Sub-Advisers and to
recommend their hiring, termination and replacement.

Distributor

The Trust's Distributor is PIMCO Funds Distributors LLC, 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.

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 quotes are not readily available may be
valued, pursuant to guidelines established by the Board of Trustees, with
reference to other securities or 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. In particular, the calculation of the NAV of the New Asia, Europe
Growth, Select World and Emerging Markets Funds may not take place
contemporaneously with the determination of the prices of foreign securities
used in the NAV calculations.

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 their 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 or persons acting at their direction
pursuant to procedures approved by the Board of Trustees. Fair valuation may
also be used by the Board of Trustees if extraordinary events occur after the
close of the relevant market but prior to the NYSE Close.


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 Information


 . Financial Service Firms. Broker-dealers, registered investment 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.

                                       31
<PAGE>

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 affiliate (normally not to exceed an annual rate of
0.35% of a 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 materials
regarding its fees and services.

 . 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" above 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 Shares

Class D shares of each Fund are continuously offered through 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, PFPC,
Inc., 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.

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 New York Stock 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.

                                       32
<PAGE>


                    Initial Investment              Subsequent Investments
                     $2,500 per Fund                     $100 per Fund


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 Shares

Except as provided below or in the applicable Fund's or series' prospectus(es),
you may exchange your Class D shares of any Fund for Class D shares of any other
Fund or series of PIMCO Funds: Pacific Investment Management 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. In addition, an exchange is generally a
taxable event which will generate capital gains or losses, and special rules may
apply in computing tax basis when determining gain or loss. 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 Advisors, 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 Advisors 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 PIMCO 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 with respect to Class D shares.

Selling Shares

You can sell (redeem) Class D shares through your financial 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 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 In Kind

The Trust had agreed to redeem shares of each Fund solely in cash 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. It is highly unlikely that your shares would ever be 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.


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 its Class D 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.

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 another series
of the Trust or PIMCO Funds: Pacific Investment Management 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.

For further information on distribution options, please contact your financial
service firm or call the Distributor at 1-888-87-PIMCO.

Tax Consequences

                                       34
<PAGE>

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 them 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
generally 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.

A Note on Foreign Investments. A Fund's investment in foreign securities may be
subject to foreign withholding taxes. In that case, the Fund's yield on those
securities would be decreased. In addition, a Fund's investments in foreign
securities or foreign currencies may increase or accelerate the Fund's
recognition of ordinary income and may affect the timing or amount of the Fund's
distributions.

This section relates only to federal income tax consequences of investing in the
Funds; the consequences under other tax laws may differ. You should consult your
tax advisor as to the possible application of foreign, state and local income
tax laws to Fund dividends and capital distributions. Please see the Statement
of Additional Information for additional information regarding the tax aspects
of investing in the Funds.

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 identified under "Summary
Information" above. It also describes characteristics and risks of additional
securities and investment techniques that are not necessarily principal
investments or strategies but may be used by the Funds from time to time. Most
of these securities and investment techniques are discretionary, which means
that the portfolio managers 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 must rely on the professional investment judgment
and skill of PIMCO Advisors, the Sub-Advisers 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.

Fixed Income Securities and Defensive Strategies

Fixed income securities are obligations of the issuer to make payments of
principal and/or interest on future dates, and include corporate and government
bonds, notes, certificates of deposit, commercial paper, convertible securities
and mortgage-backed and other asset-backed securities.

The Healthcare Innovation, Internet Innovation, Small-Cap Technology, Telecom
Innovation, Electronics Innovation, New Asia, Europe Growth, Select World and
Emerging Markets Funds will each invest primarily in common stocks, and may also
invest in other kinds of equity securities, including preferred stocks and
securities (including fixed income securities and warrants) convertible into or
exercisable for common stocks. Each of these Funds may invest a portion of their
assets in fixed income securities. The Funds may temporarily hold up to 100% of
their assets in short-term U.S. Government securities and other money market
instruments for defensive purposes in response to unfavorable market and other
conditions. The New Asia, Europe Growth, Select World and Emerging Markets Funds
may also hold up to 100% of their assets in other domestic fixed income, foreign
fixed income and equity securities principally traded in the U.S., including
obligations issued or guaranteed by a foreign government or its agencies,
authorities or instrumentalities, corporate bonds and American Depository
Receipts, for temporary defensive purposes.

The temporary defensive strategies described in this section would be
inconsistent with the investment objective and principal investment strategies
of each of the noted Funds and may adversely affect the Fund's ability to
achieve its investment objective.

Companies With Smaller Market Capitalizations

Each of the Funds may invest in securities of companies with market
capitalizations that are small compared to other publicly traded companies. The
Small-Cap Technology Fund invests primarily in smaller companies and is
especially sensitive to the risks described below. In addition, the Healthcare
Innovation, Internet Innovation, Telecom Innovation, Electronics Innovation, New
Asia, Europe Growth, Select World and Emerging Markets Funds generally have
significant exposure to these risks.

Companies which are smaller and less well-known or seasoned than larger, more
widely held companies may offer greater opportunities for capital appreciation,
but may also involve risks different from, or greater than, risks normally
associated with larger companies. Larger companies generally have greater
financial resources, more extensive research and development, manufacturing,
marketing and service capabilities, and more stability and greater depth of
management and technical personnel than smaller companies. Smaller companies may
have limited product lines, markets or financial resources or may depend on a
small, inexperienced management group. Securities of smaller companies may trade
less frequently and in lesser volume than more widely held securities and their
values may fluctuate more abruptly or erratically than securities of larger
companies. They may also trade in the over-the-counter market or on a regional
exchange, or may otherwise have limited liquidity. These securities may
therefore be more vulnerable to adverse market developments than securities of
larger companies. Also, there may

                                       36
<PAGE>

be less publicly available information about smaller companies or less market
interest in their securities as compared to larger companies, and it may take
longer for the prices of the securities to reflect the full value of a company's
earnings potential or assets.

Because securities of smaller companies may have limited liquidity, a Fund may
have difficulty establishing or closing out its positions in smaller companies
at prevailing market prices. As a result of owning large positions in this type
of security, a Fund is subject to the additional risk of possibly having to sell
portfolio securities at disadvantageous times and prices if redemptions require
the Fund to liquidate its securities positions. For these reasons, it may be
prudent for a Fund with a relatively large asset size to limit the number of
relatively small positions it holds in securities having limited liquidity in
order to minimize its exposure to such risks, to minimize transaction costs, and
to maximize the benefits of research. As a consequence, as a Fund's asset size
increases, the Fund may reduce its exposure to illiquid smaller capitalization
securities, which could adversely affect performance.


Initial Public Offerings


The Funds, particularly the Healthcare Innovation, Internet Innovation,
Small-Cap Technology, Telecom Innovation and Electronics Innovation Funds, may
purchase securities in initial public offerings (IPOs). These securities are
subject to many of the same risks of investing in companies with smaller market
capitalizations. Securities issued in IPOs have no trading history, and
information about the companies may be available for very limited periods. In
addition, the prices of securities sold in IPOs may be highly volatile. At any
particular time or from time to time a Fund may not be able to invest in
securities issued in IPOs, or invest to the extent desired because, for example,
only a small portion of the securities being offered in an IPO may be made
available to the Fund or because under certain market conditions few companies
may issue securities in IPOs. In addition, as a Fund increases in size, the
impact of IPOs on the Fund's performance will generally decrease.

Foreign Securities


The New Asia, Europe Growth, Select World and Emerging Markets Funds normally
invest principally in securities of foreign issuers, securities traded
principally in securities markets outside the United States and/or securities
denominated in foreign currencies (together, "foreign securities"). The
Healthcare Innovation, Internet Innovation, Small-Cap Technology, Telecom
Innovation and Electronics Innovation Funds may invest up to 15% of their
respective assets in foreign securities, and may invest without limit in
American Depository Receipts ("ADRs").


All of the Funds may invest in ADRs, European Depository Receipts ("EDRs") and
Global Depository Receipts ("GDRs"). ADRs are dollar-denominated receipts issued
generally by domestic banks and representing the deposit with the bank of a
security of a foreign issuer, and are publicly traded on exchanges or
over-the-counter in the United States. EDRs are receipts similar to ADRs and are
issued and traded in Europe. GDRs may be offered privately in the United States
and also traded in public or private markets in other countries.

Investing in foreign securities involves special risks and considerations not
typically associated with investing in U.S. securities and shareholders should
consider carefully the substantial risks involved for Funds that invest in these
securities. 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, rate 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.

Emerging Market Securities

                                       37
<PAGE>

The Funds may invest in securities of issuers based in or that trade principally
in countries with developing (or "emerging market") economies. The Emerging
Markets Fund is particularly susceptible to these risks because it invests
principally in companies located in emerging markets countries. The New Asia and
Select World Funds also have substantial exposure to these risks because these
Funds may invest significant portions of their assets in emerging market
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; and possible
repatriation of investment income and capital. In addition, foreign investors
may be required to register the proceeds of sales, and future economic or
political crises could lead to price controls, forced mergers, expropriation or
confiscatory taxation, seizure, nationalization or the 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 market 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.


Special Risks of Investing in Russian and Other Eastern European Securities. The
Select World and Emerging Markets Funds may invest a significant portion of
their assets in securities of issuers located in Russia and in other Eastern
European countries. While investments in securities of such issuers are subject
generally to the same risks associated with investments in other emerging market
countries described above, the political, legal and operational risks of
investing in Russian and other Eastern European issuers, and of having assets
custodied within these countries, may be particularly acute. A risk of
particular note with respect to direct investment in Russian securities is the
way in which ownership of shares of companies is normally recorded. When a Fund
invests in a Russian issuer, it will normally receive a "share extract," but
that extract is not legally determinative of ownership. The official record of
ownership of a company's share is maintained by the company's share registrar.
Such share registrars are completely under the control of the issuer, and
investors are provided with few legal rights against such registrars.

Foreign Currencies

A Fund that invests directly in foreign currencies or in securities that trade
in, and receive revenues in, foreign currencies will be subject to currency
risk. The New Asia, Europe Growth, Select World and Emerging Markets Funds are
particularly sensitive to this risk.

Foreign currency exchange rates may fluctuate significantly over short periods
of time. They generally are determined by supply and demand 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. The Europe Growth Fund is especially susceptible
to risks associated with the introduction of the euro because it invests
principally in European companies, many of which are located in European
Monetary Union countries. The euro 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. The Funds may enter into forward foreign currency
exchange contracts, primarily to reduce the risks of adverse changes in foreign
exchange rates. In addition, the Funds may buy and sell foreign

                                       38
<PAGE>

currency futures contracts and options on foreign currencies and foreign
currency 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.
Contracts to sell foreign currency would limit any potential gain which might be
realized by a Fund if the value of the hedged currency increases. A Fund may
enter into these contracts to hedge against foreign exchange risk arising from
the Fund's investment or anticipated investment in securities denominated in
foreign currencies. 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.

The New Asia, Europe Growth, Select World and Emerging Markets Funds may also
enter into these contracts for purposes of increasing exposure to a foreign
currency or to shift exposure to foreign currency fluctuations from one currency
to another. To the extent that it does so, a Fund will be subject to the
additional risk that the relative value of currencies will be different than
anticipated by the Fund's portfolio manager. The Funds 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. Each Fund will segregate assets determined
to be liquid by PIMCO Advisors or a Sub-Adviser 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.

Corporate Debt Securities

Corporate debt securities are subject to the risk of the issuer's inability to
meet principal and interest payments on the 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 durations tend to be more sensitive to
interest rate movements than those with shorter durations.

Convertible Securities

Each Fund may invest in convertible securities. Convertible securities are
generally preferred stocks and other securities, including fixed income
securities and warrants, that are convertible into or exercisable for common
stock at either a stated price or a stated 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. While convertible securities
generally offer lower interest or dividend yields than non-convertible fixed
income securities of similar quality, their value tends to increase as the
market value of the underlying stock increases and to decrease when the value of
the underlying stock decreases. Also, 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.

Derivatives

Each Fund may, but is not required to, use a number of 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. 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.

Examples of derivative instruments include options contracts, futures contracts,
options on futures contracts and swap agreements. The Funds may purchase and
sell (write) call and put options on securities, securities indexes and foreign
currencies. Each Fund may purchase and sell futures contracts and options
thereon with respect to securities, securities indexes and foreign currencies. A
description of these and other derivative instruments that the Funds

                                       39
<PAGE>

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 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.

Leveraging 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 Advisors or a
Sub-Adviser 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 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 (taxed at ordinary income tax rates when distributed to
shareholders who are individuals) than if the Fund had not used such
instruments.

                                       40
<PAGE>

Equity-Linked Securities


The Funds may invest up to 15% of their assets in equity-linked securities.
Equity-linked securities are privately issued securities whose investment
results are designed to correspond generally to the performance of a specified
stock index or "basket" of stocks, or sometimes a single stock. To the extent
that a Fund invests in equity-linked securities whose return corresponds to the
performance of a foreign securities index or one or more of foreign stocks,
investing in equity-linked securities will involve risks similar to the risks of
investing in foreign equity securities. See "Foreign Securities" above. In
addition, an investing Fund bears the risk that the issuer of an equity-linked
security may default on its obligations under the security. Equity-linked
securities may be considered illiquid and thus subject to the Funds'
restrictions on investments in illiquid securities.

Credit Ratings and Unrated Securities

The Funds may invest in securities based on their credit ratings assigned by
rating agencies such as Moody's Investors Service, Inc. ("Moody's") and Standard
& Poor's Ratings Services ("S&P"). Moody's, S&P and other rating agencies are
private services that provide ratings of the credit quality of fixed income
securities, including convertible securities. The Appendix to the Statement of
Additional Information 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 risk. 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 Advisors and the Sub-Advisers do not rely
solely on credit ratings, and develop their 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.

High Yield Securities


Securities rated lower than Baa by Moody's or lower than BBB by S&P are
sometimes referred to as "high yield securities" or "junk bonds." The Funds may
invest in these securities. 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, these securities may be subject to greater
levels of interest rate, credit and liquidity risk. These securities typically
entail greater potential price volatility and may be less liquid than
higher-rated securities. They may be regarded as predominately speculative with
respect to the issuer's continuing ability to meet principal and interest
payments and may also be more susceptible to real or perceived adverse economic
and competitive industry conditions than higher-rated securities.

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 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 the party arranging
the loan.

Short Sales

Each Fund may make short sales as part of its overall portfolio management
strategies or to offset a potential decline in the 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. A Fund may only enter into short selling
transactions if the security sold short is held in the Fund's portfolio or if
the Fund has the right to acquire the security without the payment of further
consideration. For these purposes, a Fund may also hold or have the right to
acquire securities which, without the

                                       41
<PAGE>

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.

When-Issued, Delayed Delivery and Forward Commitment Transactions

Each Fund may purchase securities which it is eligible to purchase on a
when-issued basis, may purchase and sell such securities for delayed delivery
and may make contracts to purchase such securities for a fixed price at a future
date beyond normal settlement time (forward commitments). When-issued
transactions, delayed delivery purchases and forward commitments involve a risk
of loss if the value of the securities declines prior to the settlement date.
This risk is in addition to the risk that the Fund's other assets will decline
in 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 Agreements

Each Fund may enter into repurchase agreements, in which the Fund purchases a
security from a bank or broker-dealer that 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. Those
Funds whose investment objectives do not include the earning of income will
invest in repurchase agreements only as a cash management technique with respect
to that portion of its portfolio maintained in cash. Repurchase agreements
maturing in more than seven days are considered illiquid securities.

Reverse Repurchase Agreements and Other Borrowings

Each Fund may enter into reverse repurchase agreements, subject to the Fund's
limitations on borrowings. A reverse repurchase agreement involves the sale of a
security by a Fund and its agreement to repurchase the instrument at a specified
time and price, and may be considered a form of borrowing for some purposes. A
Fund will segregate assets determined to be liquid by PIMCO Advisors or a
Sub-Adviser in accordance with procedures established by the Board of Trustees
to cover its obligations under reverse repurchase agreements. 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 and other forms of borrowings may
create leveraging risk for a Fund.

Illiquid Securities

Each Fund may invest in securities that are illiquid so long as not more than
15% of the value of the Fund's net assets (taken at market value at the time of
investment) would be invested in such 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 held by the Fund, 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. Please
see "Investment Objectives and Policies" in the Statement of Additional
Information for a listing of various securities that are generally considered to
be illiquid for these purposes. 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 in Other Investment Companies


The New Asia, Europe Growth, Select World and Emerging Markets Funds may each
invest up to [10%] of their assets in securities of other investment companies,
such as closed-end management investment companies, or in

                                       42
<PAGE>

pooled accounts or other investment vehicles which invest in foreign markets.
The Healthcare Innovation, Internet Innovation, Small-Cap Technology, Telecom
Innovation and Electronics Innovation Funds may invest up to 5% of their assets
in such securities. 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.

Portfolio Turnover

The length of time a Fund has held a particular security is not 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 active and frequent
trading of portfolio securities to achieve its investment objective and
principal investment strategies, 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 taxed at ordinary income tax rates
when distributed to shareholders who are individuals). The trading costs and tax
effects associated with portfolio turnover may adversely affect a Fund's
performance.

Changes in Investment Objectives and Policies

The investment objective of each Fund described in this Prospectus may be
changed by the Board of Trustees without shareholder approval. Unless otherwise
stated in the Statement of Additional Information, all investment policies of
the Funds may be changed by the Board of Trustees without shareholder approval.
If there is a change in a Fund's investment objective or policies, including a
change approved by shareholder vote, shareholders should consider whether the
Fund remains an appropriate investment in light of their then current financial
position and needs.

New Funds


In addition to the risks described under "Summary of Principal Risks" above and
in this section, the Funds are newly formed and therefore have no history upon
which investors can evaluate their likely performance. Also, it is possible that
a Fund may invest in securities offered in initial public offerings and other
types of transactions (such as private placements) which, because of the Fund's
size, may have a disproportionate impact on the Fund's performance results. The
Funds would not necessarily have achieved the same performance results if their
aggregate net assets had been greater.

Percentage Investment Limitations

Unless otherwise stated, all percentage limitations on Fund investments listed
in this Prospectus will apply at the time of investment. A Fund would not
violate these limitations unless an excess or deficiency occurs or exists
immediately after and as a result of an investment.

Other Investments and Techniques

The Funds may invest in other types of securities and use a variety of
investment techniques and strategies which are not described in this Prospectus.
These securities and techniques may subject the Funds to additional risks.
Please see the Statement of Additional Information for additional information
about the securities and investment techniques described in this Prospectus and
about additional securities and techniques that may be used by the Funds.

which has been filed with the Securities and Exchange Commission ("SEC") and
portions of which are incorporated herein by reference.  In the Institutional
Prospectus, references to the "Funds" or a "Fund" are deemed to refer to PIMCO
Select Value Fund unless otherwise set forth herein or therein or unless the
context otherwise requires.

                            ________________________

THE SECURITIES OFFERED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT

INFORMATION WITH RESPECT TO THE SHARES EXCEPT SUCH INFORMATION AS IS CONTAINED
IN THIS MEMORANDUM AND IN THE STATEMENT OF ADDITIONAL INFORMATION OR IN OTHER
MATERIALS APPROVED BY THE TRUST.  NO SALES MADE HEREUNDER SHALL UNDER ANY
CIRCUMSTANCES CREATE AN IMPLICATION THAT THERE HAS BEEN NO CHANGE IN MATTERS
DISCUSSED HEREIN SINCE THE DATE HEREOF.
<PAGE>

     This Private Placement Memorandum concisely describes the information which
investors ought to know about the Fund before investing. Please read this
Memorandum carefully and keep it for further reference.  The Institutional
Prospectus and a Statement of Additional Information for the Trust dated August
4, 2000, as revised or supplemented from time to time (as so revised or
supplemented, the "Statement of Additional Information"), are available free of
charge by writing to PIMCO Funds: Multi-Manager Series, 840 Newport Center
Drive, Suite 300, Newport Beach, CA 92660 or by calling 1-800-927-4648.  The
Statement of Additional Information, which contains more detailed information
about the Fund and the Trust, has been filed with the SEC and is incorporated by
reference into this Private Placement Memorandum.

     The Fund does not intend to offer its shares for sale to the public at this
time.  The Fund may in the future offer shares to the public pursuant to an
amendment to the Trust's Registration Statement, as discussed below under
"Investment Options."

INVESTMENT OBJECTIVES, PRINCIPAL INVESTMENT STRATEGIES AND RELATED RISKS

     The Fund's investment objective is long-term growth of capital and income.
The Fund seeks to achieve its investment objective by normally investing at
least 65% of its assets in common stocks of companies with below-average
valuations whose business fundamentals are expected to improve.  Although the
Fund typically invests in companies with market capitalizations of at least $5
billion at the time of investment, it may invest in companies in any
capitalization range.  To achieve income, the Fund invests a portion of its
assets in income producing (e.g., dividend-paying) stocks.  The Fund normally
invests in the securities of 20 to 30 issuers.

     The portfolio manager selects stocks for the Fund using a "value" style.
The portfolio manager invests primarily in common stocks of companies having
below-average valuations whose business fundamentals are expected to improve.
The portfolio manager determines valuation based on characteristics such as
price-to-earnings, price-to-book, and price-to-cash flow ratios.  The portfolio
manager analyzes stocks and seeks to identify the key drivers of financial
results and catalysts for change, such as new management and new or improved
products, that indicate a company may demonstrate improving fundamentals in the
future.  The portfolio manager looks to sell a stock when he believes that the
company's business fundamentals are weakening or when the stock's valuation has
become excessive.  The Fund is "non-diversified," which means it invests in a
relatively small number of issuers.

     The Fund may also invest to a limited degree in other kinds of equity
securities, including preferred stocks and convertible securities. The Fund may
invest up to 15% of its assets in foreign securities, except that it may invest
without limit in American Depository Receipts (ADRs).

     In response to unfavorable market and other conditions, the Fund may make
temporary investments of some or all of its assets in high-quality fixed income
securities.  This would be inconsistent with the Fund's investment objective and
principal strategies.

                                      -2-

PRINCIPAL RISKS
---------------

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

 .  Market Risk                         .  Management Risk
 .  Issuer Risk                         .  Foreign Investment Risk
 .  Focused Investment Risk             .  Currency Risk
 .  Credit Risk

Please see "Summary of Principal Risks" following the Fund Summaries in the
Institutional Prospectus for a description of these and other risks of investing
in the Fund.  In addition, "Summary of Principal Risks--Focused Investment Risk"
is supplemented to indicate that Funds, such as the Select Value Fund, that are
"non-diversified" because they invest in a relatively small number of issuers
may have more risk because changes in the value of a single security or the
impact of a single economic, political or regulatory occurrence may have a
greater adverse impact on the Fund's net asset value.

ADDITIONAL RISKS OF INVESTING IN THE FUND
-----------------------------------------

     In addition to the risks described under "Principal Risks" above, the Fund
is newly formed and therefore has no history upon which investors can evaluate
its likely performance.  Accordingly, there can be no assurance that the Fund
will achieve its investment objective.  Also, it is possible that the Fund may
invest in securities offered in initial public offerings and other types of
transactions (such as private placements) which, because of the Fund's small
size, may have a disproportionate impact on the Fund's performance results.  The
Fund would not necessarily achieve the same performance results if its aggregate
net assets were greater.

MANAGEMENT OF THE FUND

MANAGEMENT OF THE FUND'S INVESTMENT PORTFOLIO
---------------------------------------------

     The Fund's investment portfolio is managed by John K. Schneider, a Vice
President of the Trust.  Mr. Schneider is also a Portfolio Manager at the PIMCO
Equity Advisors division ("PIMCO Equity Advisors") of PIMCO Advisors L.P.
("PIMCO Advisors").  PIMCO Advisors serves as investment adviser to the other
series of the Trust.  Additional information about Mr. Schneider, PIMCO Advisors
and PIMCO Equity Advisors can be found in the Institutional Prospectus under
"Management of the Funds--Investment Adviser and Administrator" and  "Management
of the Funds--PIMCO Equity Advisors," which are incorporated herein by
reference.

     The Fund does not pay any fee to Mr. Schneider or to PIMCO Advisors for Mr.
Schneider's services as the Fund's portfolio manager.  However, it is
anticipated that in the future the Fund may offer shares to the public, as
discussed below under "Investment Options," at which time the Fund would,
subject to the approval of the Board of Trustees of the Trust and the
shareholders of the Fund, enter into an Investment Advisory Agreement with PIMCO
Advisors

                                      -3-
<PAGE>

pursuant to which PIMCO Advisors will assume responsibility for
managing the Fund's investment portfolio.  Mr. Schneider is expected to continue
as the Fund's portfolio manager if and when PIMCO Advisors assumes
responsibility for managing the Fund's portfolio.  The Trust believes that the
assumption by PIMCO Advisors of this responsibility will have no material effect
on how the Fund's portfolio is managed.

FUND ADMINISTRATOR
------------------

     PIMCO Advisors serves as the Fund's administrator.  Information about the
Fund's administration arrangements is found in the Institutional Prospectus
under "Management of the Funds--Administrative Fees," which is incorporated
herein by reference.  The Fund pays PIMCO Advisors administrative fees at the
annual rate of 0.25% of the Fund's average daily net assets attributable to the
Fund's Institutional Class shares, and 0.40% attributable to the Fund's Class A
shares.

DISTRIBUTOR
-----------

     The Fund's distributor is PIMCO Funds Distributor LLC, a wholly owned
subsidiary of PIMCO Advisors.  Information about the Distributor is found in the
Institutional Prospectus under the caption "Management of the Funds--
Distributor," which is incorporated herein by reference.

INVESTMENT OPTIONS

     The Fund does not intend to offer its shares for sale to the public at this
time. In the future, the Fund may offer Class A, Class B, Class C, Class D,
Institutional Class and/or Administrative Class shares to the public pursuant to
an amendment to the Trust's Registration Statement. Information about the
various classes of shares of the Fund is incorporated by reference herein as
provided below. Information about Institutional and Administrative Class shares
of the Trust is found in the section of the Institutional Prospectus captioned
"Investment Options--Institutional and Administrative Class Shares." Information
about Class A, B and C shares of the Trust is found in the Trust's Prospectus
for Class A, B and C shares dated April 3, 2000, as from time to time revised or
supplemented, in the section captioned "Investment Options--Class A, B and C
Shares," which is incorporated herein by reference. Information about Class D
shares of the Trust is found in the Trust's Prospectus for Class D shares dated
June 1, 2000, as from time to time revised or supplemented, in the section
captioned "How to Buy and Sell Shares," which is incorporated herein by
reference.

     Purchase of Fund Shares:
     ------------------------

     Until such time as the Fund offers Class A, Class B, Class C, Class D,
Institutional Class and/or Administrative Class shares as set forth above, the
Fund will have only two classes of shares, Class A and Institutional Class,
which currently are not offered for sale to the public. Currently, all investors
in the Fund must be "accredited investors" as defined in Regulation D under the
Securities Act of 1933.

     All investments are made at the net asset value next determined after an
order and payment for the investment are received by the Fund by the designated
cutoff time for each

                                      -4-
<PAGE>

accredited investor. There is no minimum initial or subsequent investment in the
Fund. The Fund reserves the right to cease accepting investments in the Fund at
any time or to reject any investment order.

     Shares may be purchased (i) in cash, (ii) in exchange for securities
subject to the determination by the Fund that the securities to be exchanged are
acceptable, or (iii) by a combination of such securities and cash.  Securities
acceptable to the Fund as consideration for Fund shares will be valued as set
forth under "How Fund Shares are Priced" in the Institutional Prospectus as of
the time of the next determination of net asset value after such acceptance.
All dividends, subscription or other rights which are reflected in the market
price of accepted securities at the time of valuation become the property of the
Fund and must be delivered to the Trust upon receipt by the investor from the
issuer.  A gain or loss for federal income tax purposes may be realized by
investors upon the exchange, depending upon the investor's basis in the
securities tendered.  The Fund will not approve securities as acceptable
consideration for Fund shares unless (i) the Fund, in its sole discretion,
believes the securities are appropriate investments for the Fund; (ii) the
investor represents and agrees that all securities offered to the Fund are not
subject to any restrictions upon their sale by the Fund under the Securities Act
of 1933, or otherwise; and (iii) the securities may be acquired under the
investment restrictions applicable to the Fund.

     Redemption of Fund Shares:
     --------------------------

     An investor in the Fund may redeem all or a portion of its investment at
the net asset value next determined after receipt by the Fund of a redemption
request in proper form on any day the New York Stock Exchange ("Exchange") is
open for business ("business day").  The redemption request must be received by
the close of regular trading on the Exchange (normally 4:00 p.m. Eastern time).
Proceeds of the redemption will be paid as promptly as possible but in any event
within seven business days after receipt of the request.

     If the Fund determines, in its sole discretion, that it would be
detrimental to the best interests of the remaining shareholders of the Fund to
make payment wholly or partly in cash, the Fund may pay the redemption price in
whole or in part by a distribution in-kind of securities held by the Fund in
lieu of cash.  Securities used to redeem Fund shares in-kind will be valued in
accordance with the Fund's procedures for valuation described under "How Fund
Shares are Priced" in the Institutional Prospectus.  Securities distributed by
the Fund in-kind will be selected by the Fund in light of the Fund's objective
and will not generally represent a pro rata distribution of each security held
in the Fund's portfolio.  Any in-kind redemptions will be of readily marketable
securities to the extent available.  Investors may incur brokerage charges on
the sale of any such securities so received in payment of redemptions.

     The Fund may suspend the right of redemption and may postpone payment for
more than seven days when the Exchange is closed for other than weekends or
holidays, or if permitted by the rules of the Securities and Exchange Commission
during periods when trading on the Exchange is restricted or during an emergency
which makes it impracticable for the Fund to dispose of its securities or to
fairly determine the value of the net assets of the Fund, or during

                                      -5-
<PAGE>

any other period permitted by the Securities and Exchange Commission for the
protection of investors.

     Currently, the Fund does not charge any sales load, contingent deferred
sales charge ("CDSC") or Rule 12b-1 fees, although Class A, B, C and D and
Administrative Class shares may charge sales loads, CDSCs and/or 12b-1 fees.

CHANGES IN INVESTMENT OBJECTIVES AND POLICIES

     The investment objective of the Fund described above may be changed by the
Board of Trustees without shareholder approval.  Unless otherwise stated in the
Statement of Additional Information, all investment policies of the Fund may be
changed by the Board of Trustees without shareholder approval.  If there is a
change in the Fund's investment objective or policies, including a change
approved by shareholder vote, shareholders should consider whether the Fund
remains an appropriate investment in light of their then current financial
position and needs.

ADVISER/SUB-ADVISER RELATIONSHIP

     PIMCO Advisors is permitted to enter into new or amended sub-advisory
agreements with one or more sub-advisers with respect to the Fund without
obtaining shareholder approval of such agreements, subject to the conditions of
an exemptive order that has been granted by the Securities and Exchange
Commission. One of the conditions requires the Board of Trustees to approve any
such agreement. In addition, the exemptive order prohibits PIMCO Advisors from
entering into sub-advisory agreements with affiliates of PIMCO Advisors without
shareholder approval, unless those affiliates are substantially wholly-owned by
PIMCO Advisors.

ADDITIONAL INFORMATION

     Information about how Fund shares are priced, Fund distributions and the
tax consequences of investing in the Fund can be found in the sections of the
Institutional Prospectus captioned, respectively, "How Fund Shares Are Priced,"
"Fund Distributions," and "Tax Consequences," which are incorporated herein by
reference.  The Fund intends to declare and distribute income dividends at least
annually. In addition, the Fund intends to distribute any capital gains it
earns from the sale of portfolio securities to shareholders no less frequently
than  annually.

3.  Investment Objectives and Policies.

    In addition to the principal investment strategies and the principal risks
of the Fund described in the Private Placement Memorandum, the Fund may employ
other investment practices and may be subject to additional risks.  The Fund may
invest in the same securities and other instruments and use the same investment
techniques as the PIMCO Renaissance Fund.  Such securities, instruments and
investment techniques are described under "Investment Objectives and Policies"
in the Statement of Additional Information.

4.  Investment Restrictions.

    Fundamental Policies
    --------------------

    The investment restrictions set forth below are fundamental policies of the
Fund and may not be changed without shareholder approval by vote of a majority
of the outstanding voting securities of the Fund.  Under these restrictions:

    1. the Fund may borrow money to the maximum extent permitted by law,
including without limitation (i) borrowing from banks or entering into reverse
repurchase agreements, or employing similar investment techniques, and pledging
its assets in connection therewith, if immediately after each borrowing and
continuing thereafter, there is asset coverage of 300%, and (ii) entering into
reverse repurchase agreements and transactions in options, futures, options on
futures, and forward foreign currency contracts;

    2. the Fund may not pledge, hypothecate, mortgage or otherwise encumber its
assets in excess of 10% of such Fund's total assets (taken at cost) and then
only to secure borrowings permitted by Restriction (a) 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.);

    3. the Fund may not underwrite securities issued by other persons except to
the extent that, in connection with the disposition of its portfolio
investments, it may be deemed to be an underwriter under federal securities
laws;

    4. the Fund may not 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;

                                      -2-
<PAGE>

    5. the Fund may not acquire more than 10% of the voting securities of any
issuer, both with respect to the Fund and to the other series of the Trust to
which this policy relates, in the aggregate;

    6. the Fund may not concentrate more than 25% of the value of its total
assets in any one industry;

    7. the Fund may not purchase or sell commodities or commodity contracts
except that the Fund may purchase and sell financial futures contracts and

                                    THE TRUST

     PIMCO Funds: Multi-Manager Series (the "Trust"), is an open-end management
investment company ("mutual fund") that currently consists of thirty-eight
separate investment series, although not all of these series currently offer
their shares to the public. Except for the Select Growth Fund, each of these
series is "diversified" within the meaning of the Investment Company Act of
1940, as amended (the "1940 Act"). The following twenty-nine series (the
"Funds") invest directly in common stocks and other securities and instruments:
the Equity Income Fund, the Value Fund, the Renaissance Fund, the Tax-Efficient
Equity Fund, the Enhanced Equity Fund, the Growth Fund, the Mega-Cap Fund, the
Capital Appreciation Fund, the Mid-Cap Fund (f/k/a the "Mid-Cap Growth Fund"),
the Select Growth Fund (f/k/a the "Core Equity Fund"), the Growth & Income Fund
(f/k/a the "Mid-Cap Equity Fund"), the Target Fund, the Small-Cap Value Fund,
the Opportunity Fund, the Micro-Cap Fund (f/k/a the "Micro-Cap Growth Fund"),
the Innovation Fund, the Global Innovation Fund, the International Fund, the
Select International Fund (f/k/a the "International Growth Fund"),the Tax-
Efficient Structured Emerging Markets Fund, the Structured Emerging Markets
Fund, the NFJ Equity Income Fund, the NFJ Value Fund and the NFJ Value 25 Fund.
Three additional series, PIMCO Funds Asset Allocation Series - 90/10 Portfolio
(the "90/10 Portfolio"), PIMCO Funds Asset Allocation Series - 60/40 Portfolio
(the "60/40 Portfolio"), and PIMCO Funds Asset Allocation Series - 30/70
Portfolio (the "30/70 Portfolio," and together with the 90/10 Portfolio and the
60/40 Portfolio, the "Portfolios"), are so-called "funds-of-funds" which invest
all of their assets in certain of the Funds and other series in the PIMCO Funds
family. Eleven other series of the Trust,the Healthcare Innovation, Telecom
Innovation, Electronics Innovation, Internet Innovation, Small-Cap
Technology,PIMCO/Allianz Select World, PIMCO/Allianz Europe Growth,
PIMCO/Allianz New Asia, PIMCO/Allianz Emerging Markets, Cadence Capital
Appreciation and Cadence Mid-Cap Funds, as of the date of this Statement of
Additional Information do not offer their shares to the public.

     The PIMCO Tax Exempt, International Developed, Emerging Markets, Balanced,
Precious Metals and Small-Cap Funds, which are referred to elsewhere in this
Statement of Additional Information, were formerly series of the Trust. The Tax
Exempt Fund reorganized with and into the Municipal Bond Fund of PIMCO Funds:
Pacific Investment Management Series ("PIMS"), an open-end series management
investment company advised by Pacific Investment Management Company LLC
("Pacific Investment Management"), in a transaction that took place on June 26,
1998. The Tax Exempt Fund was liquidated in connection with the transaction and
is no longer a series of the Trust. The International Developed and Emerging
Markets Funds reorganized with and into newly-formed series of Alleghany Funds
in a transaction that took place on April 30, 1999. The International Developed
and Emerging Markets Funds were liquidated in connection with the transaction
and are no longer series of the Trust. The Balanced Fund reorganized with and
into the Strategic Balanced Fund of PIMS in a transaction that took place on
September 17, 1999. The Balanced Fund was liquidated in connection with the
transaction and is no longer a series of the Trust. The Precious Metals Fund was
liquidated on March 3, 2000 and is no longer a series of the Trust. The
Small-Cap Fund (f/k/a the "Small-Cap Growth Fund") was liquidated on July 28,
2000 and is no longer a series of the Trust. The PIMCO Value 25 Fund is also
referred to in this Statement of Additional Information. The Value 25 Fund
transferred substantially all of its assets to the Value Fund in a transaction
that took place on March 3, 2000. As part of the transaction, the Value 25 Fund
exchanged substantially all of its assets for shares of the Value Fund, which
were then distributed to shareholders of the Value 25 Fund in complete
redemption of their interests in and liquidation of the Value 25 Fund. The Value
25 Fund was not dissolved in the transaction; instead, on or about April 3,
2000, the series constituting the Value 25 Fund was renamed the NFJ Value 25
Fund.


     The Trust was organized as a Massachusetts business trust on August 24,
1990. On January 17, 1997, the Trust and PIMCO Advisors Funds, a separate trust,
were involved in a transaction in which certain series of PIMCO Advisors Funds
reorganized into series of the Trust. In connection with this transaction, the
Trust changed its name from PIMCO Funds: Equity Advisors Series to its current
name. Prior to being known as PIMCO Funds: Equity Advisors Series, the Trust was
named PIMCO Advisors Institutional Funds, PFAMCO Funds and PFAMCO Fund.

                       INVESTMENT OBJECTIVES AND POLICIES

     In addition to the principal investment strategies and the principal risks
of the Funds and Portfolios described in the Prospectuses, each Fund may employ
other investment practices and may be subject to additional risks which are
described below. Because the following is a combined description of investment
strategies and risks for all the Funds and Portfolios, certain strategies and/or
risks described below may not apply to particular Funds and/or Portfolios.
Unless a strategy or policy described below is specifically prohibited by the
investment restrictions listed in the Prospectuses, under "Investment
Restrictions" in this Statement of Additional Information, or by applicable law,
a Fund or Portfolio may engage in each of the practices described below.

     The 90/10 Portfolio, 60/40 Portfolio and 30/70 Portfolio invest all of
their assets in certain Funds and series of PIMS. PIMS is sometimes referred to
in the Prospectuses as PIMCO Funds: Pacific Investment Management Series. These
Funds and other series in which the Portfolios invest are referred to in this
Statement as "Underlying PIMCO Funds." By investing in Underlying PIMCO Funds,
the Portfolios may have an indirect investment interest in some or all of the
securities and instruments described below, depending upon how their assets are
allocated among the Underlying PIMCO Funds. The Portfolios may also have an
indirect investment interest in other securities and instruments utilized by the
Underlying PIMCO Funds which are series of PIMS. These securities and
instruments are described in the current PIMS prospectus for Institutional Class
and Administrative Class shares and in the PIMS Statement of Additional
Information. The PIMS prospectus and statement of additional information are
incorporated in this document by reference. See "Investment Strategies of the
Portfolios--Incorporation by Reference" below.

     The Funds' sub-advisers, which are responsible for making investment
decisions for the Funds, are referred to in this section and the remainder of
this Statement of Additional Information as "Sub-Advisers." As discussed below
under "Management of the Trust--Investment Adviser," the PIMCO Equity Advisors
division of PIMCO Advisors is also referred to as a "Sub-Adviser."

U.S. Government Securities

     U.S. Government securities are obligations of, or guaranteed by, the U.S.
Government, its agencies or instrumentalities. The U.S. Government does not
guarantee the net asset value of the Funds' shares. Some U.S. Government
securities, such as Treasury bills, notes and bonds, and securities guaranteed
by the Government National Mortgage Association ("GNMA"), are supported by the
full faith and credit of the United States; others, such as those of the Federal
Home Loan Banks, are supported by the right of the issuer to borrow from the
U.S. Treasury; others, such as those of the Federal National Mortgage
Association ("FNMA"), are supported by the discretionary authority of the U.S.
Government to purchase the agency's obligations; and still others, such as those
of the Student Loan Marketing Association, are supported only by the credit of
the instrumentality. U.S. Government securities include securities that have no
coupons, or have been stripped of their unmatured interest coupons, individual
interest coupons from such securities that trade separately, and evidences of
receipt of such securities. Such securities may pay no cash income, and are
purchased at a deep discount from their value at maturity. Because interest on
zero coupon securities is not distributed on a current basis but is, in effect,
compounded, zero coupon securities tend to be subject to greater market risk
than interest-paying securities of similar maturities. Custodial receipts issued
in connection with so-called trademark zero coupon securities, such as CATs and
TIGRs, are not issued by the U.S. Treasury, and are therefore not U.S.
Government securities, although the underlying bond represented by such receipt
is a debt obligation of the U.S. Treasury. Other zero coupon Treasury securities
(e.g., STRIPs and CUBEs) are direct obligations of the U.S. Government.

Borrowing


     Subject to the limitations described under "Investment Restrictions" below,
a Fund may be permitted to borrow for temporary purposes and/or for investment
purposes. Such a practice will result in leveraging of a Fund's assets and may
cause a Fund to liquidate portfolio positions when it would not be advantageous
to do so. This borrowing may be unsecured. Provisions of the 1940 Act, require a
Fund to maintain continuous asset

                                      -2-
<PAGE>

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. 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.

     From time to time, the Trust may enter into, and make borrowings for
temporary purposes related to the redemption of shares under, a credit agreement
with third-party lenders. Borrowings made under such a credit agreement will be
allocated among the Funds and Portfolios pursuant to guidelines approved by the
Board of Trustees.

     In addition to borrowing for temporary purposes, a Fund may enter into
reverse repurchase agreements if permitted to do so under its investment
restrictions. 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. The Fund will segregate assets
determined to be liquid by the Adviser or the Fund's Sub-Adviser in accordance
with procedures established by the Board of Trustees and equal (on a daily mark-
to-market basis) to its obligations under reverse repurchase agreements with
broker-dealers (but not banks). 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. Reverse repurchase agreements will be subject to the
Funds' limitations on borrowings as specified under "Investment Restrictions"
below.

Preferred Stock

     All Funds may invest in preferred stock. Preferred stock is a form of
equity ownership in a corporation. The dividend on a preferred stock is a fixed
payment which the corporation is not legally bound to pay. Certain classes of
preferred stock are convertible, meaning the preferred stock is convertible into
shares of common stock of the issuer. By holding convertible preferred stock, a
Fund can receive a steady stream of dividends and still have the option to
convert the preferred stock to common stock.

Corporate Debt Securities

     All Funds may invest in corporate debt securities and/or hold their assets
in these securities for cash management purposes. The investment return of
corporate debt securities reflects interest earnings and changes in the market
value of the security. The market value of a corporate debt obligation may be
expected to rise and fall inversely with interest rates generally. There also
exists the risk that the issuers of the securities may not be able to meet their
obligations on interest or principal payments at the time called for by an
instrument.

     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 ratings criteria set forth for the Fund, or, if unrated, are deemed to
be comparable in quality to corporate debt securities in which the Fund may
invest. 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.

                                      -3-
<PAGE>

     Among the corporate debt securities in which the Funds may invest are
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.

     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.

High Yield Securities ("Junk Bonds")

     Certain of the Funds may invest in debt/fixed income securities of domestic
or foreign issuers that meet minimum ratings criteria set forth for a Fund, or,
if unrated, are of comparable quality in the opinion of the Fund's Sub-Adviser.
A description of the ratings categories used is set forth in the Appendix to
this Statement of Additional Information.

     A security is considered to be below "investment grade" quality if it is
either (1) not rated in one of the four highest rating categories by one of the
Nationally Recognized Statistical Rating Organizations ("NRSROs") (i.e., rated
Ba or below by Moody's Investors Service, Inc. ("Moody's") or BB or below by
Standard & Poor's Ratings Services ("S&P")) or (2) if unrated, determined by the
relevant Sub-Adviser to be of comparable quality to obligations so rated.

     Certain Funds, particularly the Growth & Income Fund, may invest a portion
of their assets in fixed income securities rated lower than Baa by Moody's or
lower than BBB by S&P but rated at least B by Moody's or S&P or, if not rated,
determined by the Sub-Adviser to be of comparable quality. In addition, certain
of these Funds may invest in convertible securities rated below B by Moody's or
S&P (or, if unrated, considered by the Sub-Adviser to be of comparable quality).
Securities rated lower than Baa by Moody's or lower than BBB by S&P are
sometimes referred to as "high yield" or "junk" bonds. Investors should consider
the risks associated with high yield securities before investing in these Funds.
Although each of the Funds that invests in high yield securities reserves the
right to do so at any time, as of the date of this Statement of Additional
Information, none of these Funds invest or has the present intention to invest
more than 5% of its assets in high yield securities, except that the Growth &
Income Fund may invest up to 10% of its assets in high yield securities.
Investment in high yield securities generally provides greater income and
increased opportunity for capital appreciation than investments in higher
quality securities, but it also typically entails greater price volatility as
well as principal and income risk. High yield securities are regarded as
predominantly speculative with respect to the issuer's continuing ability to
meet principal and interest payments. The market for these securities is
relatively new, and many of the outstanding high yield securities have not
endured a major business recession. A long-term track record on default rates,
such as that for investment grade corporate bonds, does not exist for this
market. Analysis of the creditworthiness of issuers of high yield securities may
be more complex than for issuers of higher quality debt/fixed income securities.
Each Fund of the Trust that may purchase high yield securities may continue to
hold such securities following a decline in their rating if in the opinion of
the Adviser or the Sub-Adviser, as the case may be, it would be advantageous to
do so. Investments in high yield securities that are eligible for purchase by
certain of the Funds are described as "speculative" by both Moody's and
S&P.

     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 than investments in higher rated debt securities, high yield
securities typically entail greater potential price volatility and may be less
liquid than investment grade debt. High yield securities may be regarded as
predominately speculative with respect to the issuer's continuing ability to
meet principal and interest payments.

Analysis of the creditworthiness of issuers of high yield securities may be more
complex than for issuers of higher quality debt securities, and achievement of a
Fund's investment objective may, to the extent of its investments in high yield
securities, depend more heavily on the Sub-Adviser's creditworthiness analysis
than would be the case if the Fund were investing in higher quality 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 are likely to be 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/fixed income 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. Even
though such securities do not pay current interest in cash, a Fund nonetheless
is required to accrue interest income on these investments and to distribute the
interest income on a current basis. Thus, a Fund could be required at times to
liquidate other investments in order to satisfy its distribution requirements.

     Prices of high yield/high risk securities have been found to be less
sensitive to interest rate changes than more highly rated investments, but more
sensitive to economic downturns or individual corporate developments. 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. Lower liquidity in secondary markets could adversely affect the value of
high yield/high risk securities held by the Funds. While lower rated securities
typically are less sensitive to interest rate changes than higher rated
securities, the market prices of high yield/high risk securities structured as
"zero coupon" or "pay-in-kind" securities may be affected to a greater extent by
interest rate changes. See Appendix A to this Statement of Additional
Information for further information regarding high yield/high risk securities.
For instance, 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.

     Debt securities are purchased and sold principally in response to current
assessments of future changes in business conditions and the levels of interest
rates on debt/fixed income securities of varying maturities, the availability of
new investment opportunities at higher relative yields, and current evaluations
of an issuer's continuing ability to meet its obligations in the future. The
average maturity or duration of the debt/fixed income securities in a Fund's
portfolio may vary in response to anticipated changes in interest rates and to
other economic factors. Securities may be bought and sold in anticipation of a
decline or a rise in market interest rates. In addition, a Fund may sell a
security and purchase another of comparable quality and maturity (usually, but
not always, of a different issuer) at approximately the same time to take
advantage of what are believed to be short-term differentials in values or
yields.

Loan Participations and Assignments

     Certain Funds may invest in fixed- and floating-rate loans arranged through
private negotiations between an issuer of debt instruments and one or more
financial institutions ("lenders"). Generally, a Fund's investments in loans are
expected to take the form of loan participations and assignments of portions of
loans from third parties.

                                      -5-
<PAGE>

     Large loans to corporations or governments may be shared or syndicated
among several lenders, usually banks. A Fund may participate in such syndicates,
or can buy part of a loan, becoming a direct lender. Participations and
assignments involve special types of risk, including 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. In assignments, a Fund's rights against
the borrower may be more limited than those held by the original lender.

Participation on Creditors Committees

     A 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 the Fund an "insider" of the issuer for purposes of the
federal securities laws, and therefore may restrict the 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 would
participate on such committees only when the Adviser and the relevant Sub-
Adviser believe 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.

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.

     Certain of the Funds may invest in floating rate debt instruments
("floaters"). The interest rate on a floater is a variable rate which is tied to
another interest rate, such as a money-market index or U.S. Treasury bill rate.
The interest rate on a floater resets periodically, typically every six months.
Because of the interest rate reset feature, floaters provide a Fund with a
certain degree of protection against rises in interest rates, but generally do
not allow the Fund to participate fully in appreciation resulting from any
general decline in interest rates.

     Certain 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 generally will exhibit greater
price volatility than a fixed rate obligation of similar credit quality. See
"Mortgage-Related and Asset-Backed Securities" below.

Mortgage-Related and Asset-Backed Securities

     All Funds that may purchase debt securities for investment purposes may
invest in mortgage-related securities, and in other asset-backed securities
(unrelated to mortgage loans) that are offered to investors currently or in the
future. 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. The value of some mortgage-
related or asset-backed securities in which the Funds invest may be particularly
sensitive to changes in prevailing interest rates, and, like other fixed income
investments, the ability of a Fund to successfully utilize these instruments may
depend in part upon the ability of the Sub-Adviser to forecast interest rates
and other economic factors correctly. See "Mortgage Pass-Through Securities"
below. Certain debt securities are also secured with collateral consisting of
mortgage-related securities. See "Collateralized Mortgage Obligations"
below.

                                      -6-
<PAGE>

     Mortgage Pass-Through Securities. Mortgage Pass-Through Securities are
securities representing interests in "pools" of mortgage loans secured by
residential or commercial real property. 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 the
Government National Mortgage Association ("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. Early repayment of principal on some mortgage-related
securities (arising from prepayments of principal due to sale of the underlying
property, refinancing, or foreclosure, net of fees and costs which may be
incurred) may expose a Fund to a lower rate of return upon reinvestment of
principal. Also, if a security subject to prepayment has been purchased at a
premium, the value of the premium would be lost in the event of prepayment. Like
other fixed income securities, 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. To the extent that
unanticipated rates of prepayment on underlying mortgages increase the effective
maturity of a mortgage-related security, the volatility of such security can be
expected to increase.

     Payment of principal and interest on some mortgage pass-through securities
(but not the market value of the securities themselves) may be guaranteed by the
full faith and credit of the U.S. Government (in the case of securities
guaranteed by the GNMA) or guaranteed by agencies or instrumentalities of the
U.S. Government (in the case of securities guaranteed by the Federal National
Mortgage Association ("FNMA") or the Federal Home Loan Mortgage Corporation
("FHLMC"). The principal governmental guarantor of mortgage-related securities
is the GNMA. GNMA is a wholly-owned U.S. Government corporation within the
Department of Housing and Urban Development. GNMA is authorized to guarantee,
with the full faith and credit of the U.S. 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 U.S. Government) include the FNMA and the 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/services 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 U.S. Government. Instead, they are supported only by the discretionary
authority of the U.S. Government to purchase the agency's obligations.

     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

                                      -7-
<PAGE>

faith and credit of the U.S. Government. Instead, they are supported only by the
discretionary authority of the U.S. Government to purchase the agency's
obligations.

     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 services 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. 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. A Fund 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 Sub- Adviser determines
that the securities meet the Fund's quality standards. Although the market for
such securities is becoming increasingly liquid, securities issued by certain
private organizations may not be readily marketable. A Fund will not purchase
mortgage-related securities or any other assets which in the Sub-Adviser's
opinion are illiquid if, as a result, more than 15% of the value of the Fund's
net assets (taken at market value at the time of investment) will be invested in
illiquid securities.

     Mortgage-related securities that are issued or guaranteed by the U.S.
Government, its agencies or instrumentalities, are not subject to a Fund's
industry concentration restrictions, see "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 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, semi-annually. 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

                                      -8-
<PAGE>

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 begin 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.

     CMOs that are issued or guaranteed by the U.S. Government or by any of its
agencies or instrumentalities will be considered U.S. Government securities by a
Fund, while other CMOs, even if collateralized by U.S. Government securities,
will have the same status as other privately issued securities for purposes of
applying a Fund's diversification tests.

     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
semi-annual 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. 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 CMO residuals or stripped mortgage-backed
securities. 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.

                                      -9-
<PAGE>

     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
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 some or all of 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 developed fairly recently 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. 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.

     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 "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, the 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 developed fairly recently. 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 and Sub-Advisers
expect that other asset-backed securities (unrelated to mortgage loans) will be
offered to investors in the future and may be purchased by the Funds that may
invest in mortgage-related securities. Several types of asset-backed securities
have already been

                                     -10-
<PAGE>

offered to investors, including Certificates for Automobile Receivables/SM/
("CARS/SM/"). CARS/SM/ 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 CARS/SM/ 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 CARS/SM/ 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
and Sub-Adviser also may invest in other types of asset-backed securities.

Convertible Securities

     Many of the Funds may invest in convertible securities. A Fund's Sub-
Adviser will select convertible securities to be purchased by the Fund based
primarily upon its evaluation of the fundamental investment characteristics and
growth prospects of the issuer of the security. As a fixed income security, a
convertible security tends to increase in market value when interest rates
decline and to decrease in value when interest rates rise. While convertible
securities generally offer lower interest or dividend yields than non-
convertible fixed income securities of similar quality, their value tends to
increase as the market value of the underlying stock increases and to decrease
when the value of the underlying stock decreases.

     Certain Funds may invest in so-called "synthetic convertible securities,"
which are composed of two or more different securities whose investment
characteristics, taken together, resemble those of convertible securities. For
example, a Fund may purchase a non-convertible debt security and a warrant or
option. The synthetic convertible differs from the true convertible security in
several respects. Unlike a true convertible security, which is a single security
having a unitary market value, a synthetic convertible comprises two or more
separate securities, each with its own market value. Therefore, the "market
value" of a synthetic convertible is the sum of the values of its fixed income
component and its convertible component. For this reason, the values of a
synthetic convertible and a true convertible security may respond differently to
market fluctuations.

Equity-Linked Securities

     Each of the Structured Emerging Markets and Tax-Efficient Structured
Emerging Markets Funds may invest up to 15% of its net assets in equity-linked
securities. The Select International may invest up to 10% of their assets in
equity-linked securities. The International Fund may invest up to 5% of its
assets in equity-linked securities. Equity-linked securities are privately
issued securities whose investment results are designed to correspond generally
to the performance of a specified stock index or "basket" of stocks, or
sometimes a single stock. To the extent that a Fund invests in an equity-linked
security whose return corresponds to the performance of a foreign securities
index or one or more foreign stocks, investing in equity-linked securities will
involve risks similar to the risks of investing in foreign equity securities.
See "Foreign Securities" in this Statement of Additional Information. In
addition, the Funds bear the risk that the issuer of an equity-linked security
may default on its obligations under the security. Equity-linked securities may
be considered illiquid and thus subject to the Funds' restrictions on
investments in illiquid securities.

                                     -11-

Foreign Securities

     The Structured Emerging Markets, Tax-Efficient Structured Emerging Markets,
Select International, International and Global Innovation Funds may invest in
U.S. dollar or foreign currency-denominated corporate debt securities of foreign
issuers; foreign equity securities, including preferred securities of foreign
issuers; certain foreign 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
Structured Emerging Markets, Tax-Efficient Structured Emerging Markets, Select
International, International and Global Innovation Funds may also invest in
common stocks issued by foreign companies. The Equity Income, Value,
Renaissance, Select Growth, Growth & Income, Growth, Target, Opportunity, and
Innovation Funds each may invest up to 15% of their respective net assets in
securities which are traded principally in securities markets outside the United
States (Eurodollar certificates of deposit are excluded for purposes of these
limitations), and may invest without limit in securities of foreign issuers that
are traded in U.S. securities markets (including American Depository Receipts
("ADRs"). The Enhanced Equity Fund may invest in common stock of foreign issuers
if it is included in the index from which stocks are selected.

      Each of the Funds may invest in ADRs. The Equity Income, Value,
Renaissance, Growth, Target, Select Growth, Growth & Income, Opportunity,
Innovation, Structured Emerging Markets, Tax-Efficient Structured Emerging
Markets, Select International, International and Global Innovation Funds may
invest in European Depository Receipts ("EDRs") or Global Depository Receipts
("GDRs"). ADRs are dollar-denominated receipts issued generally by domestic
banks and represent the deposit with the bank of a security of a foreign issuer.
EDRs are foreign currency-denominated receipts similar to ADRs and are issued
and traded in Europe, and are publicly traded on exchanges or over-the-counter
in the United States. GDRs may be offered privately in the United States and
also trade in public or private markets in other countries. ADRs, EDRs and GDRs
may be issued as sponsored or unsponsored programs. In sponsored programs, an
issuer has made arrangements to have its securities trade in the form of ADRs,
EDRs or GDRs. In unsponsored programs, the issuer may not be directly involved
in the creation of the program. Although regulatory requirements with respect to
sponsored and unsponsored programs are generally similar, in some cases it may
be easier to obtain financial information from an issuer that has participated
in the creation of a sponsored program.

     Investing in the securities of foreign issuers involves special risks and
considerations not typically associated with investing in U.S. companies. These
include: differences in accounting, auditing and financial reporting standards,
generally higher commission rates on foreign portfolio transactions, the
possibility of expropriation or confiscatory taxation, adverse changes in
investment or exchange control regulations (which may include suspension of the
ability to transfer currency from a country), political instability which can
affect U.S. investments in foreign countries and potential restrictions on the
flow of international capital. In addition, 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. Changes in foreign exchange rates will affect
the value of those securities which are denominated or quoted in currencies
other than the U.S. dollar.

     The risks of investing in foreign securities are particularly high when
securities of issuers based in developing (or "emerging market") countries are
involved. Investing in emerging market countries involves certain risks not
typically associated with investing in U.S. securities, and imposes risks
greater than, or in addition to, risks of investing in foreign, developed
countries. These risks include: greater risks of nationalization or
expropriation of assets or confiscatory taxation; currency devaluations and
other currency exchange rate fluctuations; greater social, economic and
political uncertainty and instability (including the risk of war); more
substantial government involvement in the economy; less government supervision
and regulation of the securities markets and participants in those markets;
controls on foreign investment and limitations on repatriation of invested
capital and on the Fund's ability to exchange local currencies for U.S. dollars;
unavailability of currency hedging techniques in certain emerging market
countries; the fact that companies in emerging market countries may be smaller,
less seasoned and newly organized companies; the difference in, or lack of,
auditing and financial reporting standards, which may result in unavailability
of material information about issuers; the risk that it may

                                     -12-
<PAGE>

be more difficult to obtain and/or enforce a judgment in a court outside the
United States; and greater price volatility, substantially less liquidity and
significantly smaller market capitalization of securities markets. In addition,
a number of emerging market countries restrict, to various degrees, foreign
investment in securities, and high rates of 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. Also, any
change in the leadership or politics of emerging market countries, or the
countries that exercise a significant influence over those countries, may halt
the expansion of or reverse the liberalization of foreign investment policies
now occurring and adversely affect existing investment opportunities.

     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.

     Special Risks of Investing in Russian and Other Eastern European
Securities. The International, Global Innovation, Select International, Tax-
Efficient Structured Emerging Markets and Structured Emerging Markets Funds may
each invest a portion of their assets in securities of issuers located in Russia
and in other Eastern European countries. The political, legal and operational
risks of investing in the securities of Russian and other Eastern European
issuers, and of having assets custodied within these countries, may be
particularly acute. Investments in Eastern European countries may involve acute
risks of nationalization, expropriation and confiscatory taxation. The communist
governments of a number of Eastern European countries expropriated large amounts
of private property in the past, in many cases without adequate compensation,
and there can be no assurance that such expropriation will not occur in the
future. Also, certain Eastern European countries, which do not have market
economies, are characterized by an absence of developed legal structures
governing private and foreign investments and private property.

     In addition, governments in certain Eastern European countries may require
that a governmental or quasi-governmental authority act as custodian of a Fund's
assets invested in such country. To the extent such governmental or quasi-
governmental authorities do not satisfy the requirements of the 1940 Act to act
as foreign custodians of the Fund's cash and securities, the Fund's investment
in such countries may be limited or may be required to be effected through
intermediaries. The risk of loss through governmental confiscation may be
increased in such circumstances.

     Investments in securities of Russian issuers may involve a particularly
high degree of risk and special considerations not typically associated with
investing in U.S. and other more developed markets, many of which stem from
Russia's continuing political and economic instability and the slow-paced
development of its market economy. Investments in Russian securities should be
considered highly speculative. Such risks and special considerations include:
(a) delays in settling portfolio transactions and the risk of loss arising out
of Russia's system of share registration and custody (see below); (b)
pervasiveness of corruption, insider trading, and crime in the Russian economic
system; (c) difficulties associated in obtaining accurate market valuations of
many Russian securities, based partly on the limited amount of publicly
available information; (d) the general financial condition of Russian companies,
which may involve particularly large amounts of inter-company debt; and (e) the
risk that the Russian tax system will not be reformed to prevent inconsistent,
retroactive and/or exorbitant taxation or, in the alternative, the risk that a
reformed tax system may result in the inconsistent and unpredictable enforcement
of the new tax laws. Also, there is the risk that the government of Russia or
other executive or legislative bodies may decide not to continue to support the
economic reform programs implemented since the dissolution of the Soviet Union
and could follow radically different political and/or economic policies to the
detriment of investors, including non-market-oriented policies such as the
support of certain industries at the expense of other sectors or investors, a
return to the centrally planned economy that existed prior to the dissolution of
the Soviet Union, or the nationalization of privatized enterprises.

     A risk of particular note with respect to direct investment in Russian
securities is the way in which ownership of shares of companies is normally
recorded. Ownership of shares (except where shares are held

                                     -13-
<PAGE>

through depositories that meet the requirements of the 1940 Act) is defined
according to entries in the company's share register and normally evidenced by
"share extracts" from the register or, in certain limited circumstances, by
formal share certificates. However, there is no central registration system for
shareholders and these services are carried out by the companies themselves or
by registrars located throughout Russia. The share registrars are controlled by
the issuer of the securities, and investors are provided with few legal rights
against such registrars. These registrars are not necessarily subject to
effective state supervision nor are they licensed with any governmental entity.
It is possible for a Fund to lose its registration through fraud, negligence or
even mere oversight. While a Fund will endeavor to ensure that its interest
continues to be appropriately recorded, which may involve a custodian or other
agent inspecting the share register and obtaining extracts of share registers
through regular confirmations, these extracts have no legal enforceability and
it is possible that subsequent illegal amendment or other fraudulent act may
deprive the Fund of its ownership rights or improperly dilute its interests. In
addition, while applicable Russian regulations impose liability on registrars
for losses resulting from their errors, it may be difficult for a Fund to
enforce any rights it may have against the registrar or issuer of the securities
in the event of loss of share registration.

     Also, although a Russian public enterprise with more than 500 shareholders
is required by law to contract out the maintenance of its shareholder register
to an independent entity that meets certain criteria, this regulation has not
always been strictly enforced in practice. Because of this lack of independence,
management of a company may be able to exert considerable influence over who can
purchase and sell the company's shares by illegally instructing the registrar to
refuse to record transactions in the share register. In addition, so-called
"financial-industrial groups" have emerged in recent years that seek to deter
outside investors from interfering in the management of companies they control.
These practices may prevent a Fund from investing in the securities of certain
Russian companies deemed suitable by the Fund's Sub-Adviser. Further, this also
could cause a delay in the sale of Russian securities held by a Fund if a
potential purchaser is deemed unsuitable, which may expose the Fund to potential
loss on the investment.

Foreign Currencies

     The Equity Income, Value, Renaissance, Select Growth, Growth & Income,
Growth, Target, Opportunity, Innovation,International, Select International,
Structured Emerging Markets, Tax-Efficient Structured Emerging Markets and
Global Innovation Funds invest directly in foreign currencies and may enter into
forward foreign currency exchange contracts to reduce the risks of adverse
changes in foreign exchange rates. In addition, the Structured Emerging Markets,
Tax-Efficient Structured Emerging Markets, International, Select International,
and Global Innovation Funds may buy and sell foreign currency futures contracts
and options on foreign currencies and foreign currency futures.

     A forward foreign currency exchange contract 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. By entering into a forward foreign
currency exchange contract, the fund "locks in" the exchange rate between the
currency it will deliver and the currency it will receive for the duration of
the contract. As a result, a Fund reduces its 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 exchange into. Contracts to sell foreign
currencies would limit any potential gain which might be realized by a Fund if
the value of the hedged currency increases. A Fund may enter into these
contracts for the purpose of hedging against foreign exchange risks arising from
the Funds' investment or anticipated investment in securities denominated in
foreign currencies. Suitable hedging transactions may not be available in all
circumstances. Also, such hedging transactions may not be successful and may
eliminate any chance for a Fund to benefit from favorable fluctuations in
relevant foreign currencies.

     The International, Global Innovation, Select International, Structured
Emerging Markets and Tax-Efficient Structured Emerging Markets Funds may also
enter into forward foreign currency exchange contracts for purposes of
increasing exposure to a foreign currency or to shift exposure to foreign
currency fluctuations from one currency to another. To the extent that they do
so, the International, Global Innovation, Select

                                     -14-
<PAGE>


International, Structured Emerging Markets and Tax-Efficient Structured Emerging
Markets Funds will be subject to the additional risk that the relative value of
currencies will be different than anticipated by the particular Fund's
Sub-Adviser. 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. A Fund will segregate assets determined to be liquid by the Adviser
or a Sub-Adviser in accordance with procedures established by the Board of
Trustees to cover forward currency contracts entered into for non-hedging
purposes. The Funds may also use foreign currency futures contracts and related
options on currencies for the same reasons for which forward foreign currency
exchange contracts are used.

     Special Risks Associated with the Introduction of the Euro. The
introduction of a single currency, the euro, on January 1, 1999 for
participating European nations in the European Economic and Monetary Union
presents unique uncertainties for European securities in the markets in which
they trade and with respect to the operation of the Funds that invest in
securities denominated in European currencies and other European securities. The
introduction of the euro will result in the redenomination of European debt and
equity securities over a period of time. Uncertainties raised by the
introduction of the euro include whether the payment and operational systems of
banks and other financial institutions will function correctly, whether clearing
and settlement payment systems developed for the new currency will be suitable,
the valuation and legal treatment of outstanding financial contracts after
January 1, 1999 that refer to existing currencies rather than the euro, and
possible adverse accounting or tax consequences that may arise from the
transition to the euro. These or other factors could cause market disruptions
and could adversely affect the value of securities and foreign currencies held
by the Funds.

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 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 generally 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 (taken at market
value at the time of investment) would be invested in such deposits, repurchase
agreements maturing in more than seven days and other illiquid assets. Each Fund
may also hold funds on deposit with its sub-custodian bank in an interest-
bearing account for temporary purposes.

     Each Fund limits its investments in United States bank obligations to
obligations of United States banks (including foreign branches) which have more
than $1 billion in total assets at the time of investment and are members of the
Federal Reserve System or are examined by the Comptroller of the Currency or
whose deposits are insured by the Federal Deposit Insurance Corporation. A Fund
also may invest in certificates of deposit of savings and loan associations
(federally or state chartered and federally insured) having total assets in
excess of $1 billion.

     The Equity Income, Value, Renaissance, Growth, Target, Select Growth,
Growth & Income, Opportunity, Innovation, International, Structured Emerging
Markets, Tax-Efficient Structured Emerging Markets, Select International and
Global Innovation Funds limit their investments in foreign bank obligations to
obligations of foreign banks (including United States branches of foreign banks)
which at the time of investment (i) have more than $10 billion, or the
equivalent in other currencies, in total assets; (ii) are among the 75 largest
foreign banks in the world in terms of total assets; (iii) have branches or
agencies (limited purpose offices which do not offer all banking services) in
the United States; and (iv) in the opinion of the relevant Sub-Adviser, are of


                                     -15-
<PAGE>

an investment quality comparable to obligations of United States banks in which
the Funds may invest. Subject to each Fund'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
above.

     Obligations of foreign banks involve certain risks associated with
investing in foreign securities described under "Foreign Securities" above,
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.

Commercial Paper

     All Funds may invest in commercial paper. Commercial paper represents
short-term unsecured promissory notes issued in bearer form by banks or bank
holding companies, corporations and finance companies. The commercial paper
purchased by the Funds consists of U.S. dollar-denominated obligations of
domestic issuers, or, additionally for the Equity Income, Value, Renaissance,
Growth, Target, Select Growth, Growth & Income, Opportunity,
Innovation,Structured Emerging Markets, Tax-Efficient Structured Emerging
Markets, International, Select International and Global Innovation Funds,
foreign currency-denominated obligations of domestic or foreign issuers which,
at the time of investment, are (i) rated "P-1" or "P-2" by Moody's or "A-1" or
"A-2" or better by S&P, (ii) issued or guaranteed as to principal and interest
by issuers or guarantors having an existing debt security rating of "A" or
better by Moody's or "A" or better by S&P, or (iii) securities which, if not
rated, are, in the opinion of the Sub-Adviser, of an investment quality
comparable to rated commercial paper in which the Fund may invest. The rate of
return on commercial paper may be linked or indexed to the level of exchange
rates between the U.S. dollar and a foreign currency or currencies.

Money Market Instruments

     Each of the Funds may invest at least a portion of its assets in the
following kinds of money market instruments: (1) short-term U.S. Government
securities; (2) certificates of deposit, bankers' acceptances and other bank
obligations rated in the two highest rating categories by at least two NRSROs,
or, if rated by only one NRSRO, in such agency's two highest grades, or, if
unrated, determined to be of comparable quality by the Adviser or a Sub-Adviser.
Bank obligations must be those of a bank that has deposits in excess of $2
billion or that is a member of the Federal Deposit Insurance Corporation. A Fund
may invest in obligations of U.S. branches or subsidiaries of foreign banks
("Yankee dollar obligations") or foreign branches of U.S. banks ("Eurodollar
obligations"); (3) commercial paper rated in the two highest rating categories
by at least two NRSROs, or, if rated by only one NRSRO, in such agency's two
highest grades, or, if unrated, determined to be of comparable quality by the
Adviser or a Sub-Adviser; (4) corporate obligations with a remaining maturity of
397 days or less whose issuers have outstanding short-term debt obligations
rated in the highest rating category by at least two NRSROs, or, if rated by
only one NRSRO, in such agency's highest grade, or, if unrated, determined to be
of comparable quality by the Adviser or a Sub-Adviser; and (5) repurchase
agreements with domestic commercial banks or registered broker-dealers.

Derivative Instruments

     The following describes certain derivative instruments and products in
which certain Funds may invest and risks associated therewith.

     The Funds might not employ any of the strategies described below, and no
assurance can be given that any strategy used will succeed. Also, suitable
derivative and/or hedging transactions may not be available in all circumstances
and there can be no assurance that a Fund will be able to identify or employ a
desirable derivative and/or hedging transaction at any time or from time to
time.

     Options on Securities and Indexes. As described under "Characteristics and
Risks of Securities and Investment Techniques--Derivatives" in the Prospectuses,
certain Funds may purchase and sell both put and call options on equity, 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 National Association of Securities Dealers Automated Quotations
("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. Among other reasons, a Fund may purchase put options to
protect holdings in an underlying or related security against a decline in
market value, and may purchase call options to protect against increases in the
prices of securities it intends to purchase pending its ability to invest in
such securities in an orderly manner.

     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 under lying 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 Sub-Adviser in accordance with procedures established by the Board of
Trustees in such amount are segregated) 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 segregates assets determined to be liquid by the Adviser or
a Sub-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 segregated by the Fund in assets
determined to be liquid by the Adviser or a Sub-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 Sub-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 segregated by the Fund in assets determined to be liquid by
the Adviser or a Sub-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,

                                     -17-
<PAGE>

exchange, underlying security or index, exercise price, and expiration). In
addition, 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. There can be no assurance, however, that a
closing purchase or sale transaction can be effected when the Fund desires.

     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.

     OTC Options. The Equity Income, Value, Renaissance, Growth, Select Growth,
Growth & Income, Target, Opportunity, Innovation,International, Select
International and Global Innovation Funds may enter into over-the-counter
("OTC") options transactions only with primary dealers in U.S. Government
securities and only pursuant to agreements that will assure that the relevant
Fund will at all times have the right to repurchase the option written by it
from the dealer at a specified formula price. Over-the-counter options in which
certain Funds may invest 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. The
Funds may be required to treat as illiquid over-the-counter options purchased
and securities being used to cover certain written over-the-counter options, and
they will treat the amount by which such formula price exceeds the intrinsic
value of the option (i.e., the amount, if any, by which the market price of the
underlying security exceeds the exercise price of the option) as an illiquid
investment.

     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 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.

     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 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

                                     -18-
<PAGE>

of the put or call option may move more or less than the price of the related
security. Furthermore, if trading restrictions or suspensions are imposed on the
options markets, a Fund may be unable to close out a position. Similarly, 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.

     For each of the International, Select International,Renaissance, Growth,
Target, Opportunity,Global Innovation and Innovation Funds, in the case of a
written call option on a securities index, the Fund will own corresponding
securities whose historic volatility correlates with that of the index.

     Foreign Currency Options. The Equity Income, Global Innovation, Growth,
Innovation, International, Select International, Growth & Income, Opportunity,
Renaissance, Select Growth, Structured Emerging Markets, Target, Tax-Efficient
Structured Emerging Markets and Value Funds may buy or sell put and call options
on foreign currencies as a hedge against changes in the value of the U.S. dollar
(or another currency) in relation to a foreign currency in which a Fund's
securities may be denominated. In addition, each of the Funds that may buy or
sell foreign currencies 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.


     Futures Contracts and Options on Futures Contracts. Certain Funds may use
interest rate, foreign currency or index futures contracts. The Equity Income,
Global Innovation, Growth, Innovation, International, Select International,
Growth & Income, Opportunity, Renaissance, Select Growth, Structured Emerging
Markets, Target, Tax-Efficient Structured Emerging Markets and Value Funds may
invest in foreign exchange futures contracts and options thereon ("futures
options") that are traded on a U.S. or foreign exchange or board of trade, or
similar entity, or quoted on an automated quotation system as an adjunct to
their securities activities. The Equity Income, Global Innovation, Growth,
Innovation, International, Select International, Growth & Income, Opportunity,
Renaissance, Select Growth, Structured Emerging Markets, Target, Tax-Efficient
Structured Emerging Markets and Value Funds may purchase and sell futures
contracts on various securities indexes ("Index Futures") and related options
for hedging purposes and for investment purposes. A Fund's purchase and sale of
Index Futures is limited to contracts and exchanges which have been approved by
the Commodity Futures Trading Commission ("CFTC"). Each of the International,
Global Innovation, Select International, Structured Emerging Markets and
Tax-Efficient Structured Emerging Markets Funds may invest to a significant
degree in Index Futures on stock indexes and related options (including those
which may trade outside of the United States) as an alternative to purchasing
individual stocks in order to adjust the Fund's exposure to a particular market.
These Funds may invest in Index Futures and related options when a Sub-Adviser
believes that there are not enough attractive securities available to maintain
the standards of diversification and liquidity set for a Fund pending investment
in such securities if or when they do become available. Through the use of Index
Futures and related options, a Fund may diversify risk in its portfolio without
incurring the substantial brokerage costs which may be associated with
investment in the securities of multiple issuers. A Fund may also avoid
potential market and liquidity problems which may result from increases in
positions already held by the Fund.

     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. An Index Future 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 a securities index ("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 unit is the value of the relevant Index from time to time.
Entering into a contract to buy units is commonly referred to as buying or
purchasing a contract or holding a long

                                     -19-

position in an Index. Index Futures contracts can be traded through all major
commodity brokers. A Fund's purchase and sale of Index Futures is limited to
contracts and exchanges which have been approved by the CFTC. A Fund will
ordinarily be able to close open positions on the futures exchange on which
Index Futures are then traded at any time up to and including the expiration
day. As described below, a Fund will be required to segregate initial margin in
the name of the futures broker upon entering into an Index Future. Variation
margin will be paid to and received from the broker on a daily basis as the
contracts are marked to market. For example, when a Fund has purchased an Index
Future and the price of the relevant Index has risen, that position will have
increased in value and the Fund will receive from the broker a variation margin
payment equal to that increase in value. Conversely, when a Fund has purchased
an Index Future and the price of the relevant Index has declined, the position
would be less valuable and the Fund would be required to make a variation margin
payment to the broker.

     A Fund may close open positions on the futures exchanges on which Index
Futures are traded at any time up to and including the expiration day. All
positions which remain open at the close of the last business day of the
contract's life are required to settle on the next business day (based upon the
value of the relevant index on the expiration day), with settlement made with
the appropriate clearing house. Because the specific procedures for trading
foreign stock Index Futures on futures exchanges are still under development,
additional or different margin requirements as well as settlement procedures may
be applicable to foreign stock Index Futures at the time a Fund purchases such
instruments. Positions in Index Futures may be closed out by a Fund only on the
futures exchanges upon which the Index Futures are then traded.

     The following example illustrates generally the manner in which Index
Futures operate. The Standard & Poor's 100 Stock Index is composed of 100
selected common stocks, most of which are listed on the New York Stock Exchange.
The S&P 100 Index assigns relative weightings to the common stocks included in
the Index, and the Index fluctuates with changes in the market values of those
common stocks. In the case of the S&P 100 Index, contracts are to buy or sell
100 units. Thus, if the value of the S&P 100 Index were $180, one contract would
be worth $18,000 (100 units x $180). The Index Future specifies that no delivery
of the actual stocks making up the Index will take place. Instead, settlement in
cash must occur upon the termination of the contract, with the settlement being
the difference between the contract price and the actual level of the Index at
the expiration of the contract. For example, if a Fund enters into a futures
contract to buy 100 units of the S&P 100 Index at a specified future date at a
contract price of $180 and the S&P 100 Index is at $184 on that future date, the
Fund will gain $400 (100 units x gain of $4). If the Fund enters into a futures
contract to sell 100 units of the Index at a specified future date at a contract
price of $180 and the S&P 100 Index is at $182 on that future date, the Fund
will lose $200 (100 units x loss of $2).

     A public market exists in futures contracts covering a number of Indexes as
well as financial instruments and foreign currencies, including but not limited
to: 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
European Currency Unit ("ECU"). It is expected that other futures contracts in
which the Funds may invest will be developed and traded in the future.

     Certain Funds may purchase and write call and put futures options. 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 holder acquires a short position and
the writer is assigned the opposite long position.

     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 in the case of futures options, for which an established
over-the-counter market exists.

                                     -20-
<PAGE>

     When a purchase or sale of a futures contract is made by a Fund, the Fund
is required to segregate a specified amount of assets determined to be liquid by
the Adviser or a Sub-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.

     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 (i.e.,
with the 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. Any transaction costs must also be included in these calculations.

     Limitations on Use of Futures and Futures Options. The Funds may only enter
into futures contracts or futures options which are standardized and traded on a
U.S. or foreign exchange or board of trade, or similar entity, or quoted on an
automated quotation system. The Funds may enter into positions in futures
contracts and related options for "bona fide hedging" purposes (as such term is
defined in applicable regulations of the CFTC), for example, to hedge against
changes in interest rates, foreign currency exchange rates or securities prices.
In addition, certain Funds may utilize futures contracts for investment
purposes. For instance, the International, Global Innovation, Select
International, Structured Emerging Markets and Tax-Efficient Structured Emerging
Markets Funds may invest to a significant degree in Index Futures on stock
indexes and related options (including those which may trade outside of the
United States) as an alternative to purchasing individual stocks in order to
adjust their exposure to a particular market. 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 segregate (and mark-to-
market on a daily basis) assets determined to be liquid by the Adviser or a Sub-
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 total 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 segregate (and mark-to-market
on a daily basis) assets determined to be liquid by the Adviser or a Sub-Adviser
in accordance with procedures established by the Board

                                     -21-
<PAGE>

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 Future, 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 segregate
(and mark-to-market on a daily basis) assets determined to be liquid by the
Adviser or a Sub-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.

     When selling a put option on a futures contract, a Fund will segregate (and
mark-to-market on a daily basis) assets determined to be liquid by the Adviser
or a Sub-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.

     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. Some of the risk may be
caused by an imperfect correlation between movements in the price of the futures
contract and the price of the security or other investment being hedged. The
hedge will not be fully effective where there is such imperfect correlation.
Also, an incorrect correlation could result in a loss on both the hedged
securities in a Fund and the hedging vehicle, so that the portfolio return might
have been greater had hedging not been attempted. For example, if the price of
the futures contract moves more than the price of the hedged security, a Fund
would experience either a loss or gain on the future which is not completely
offset by movements in the price of the hedged securities. 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. To compensate for imperfect correlations, a Fund
may purchase or sell futures contracts in a greater dollar amount than the
hedged securities if the volatility of the hedged securities is historically
greater than the volatility of the futures contracts. Conversely, a Fund may
purchase or sell fewer contracts if the volatility of the price of the hedged
securities is historically less than that of the futures contracts. The risk of
imperfect correlation generally tends to diminish as the maturity date of the
futures contract approaches. 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. Also, suitable hedging transactions may not be available in all
circumstances.

     Additionally, the price of Index Futures may not correlate perfectly with
movement in the relevant index due to certain market distortions. First, all
participants in the futures market are subject to margin deposit and maintenance
requirements. Rather than meeting additional margin deposit requirements,
investors may close futures contracts through offsetting transactions which
could distort the normal relationship between the index and futures markets.
Second, the deposit requirements in the futures market are less onerous than
margin requirements in the securities market, and as a result, the futures
market may attract more speculators than does the securities


                                     -22-
<PAGE>

market. Increased participation by speculators in the futures market may also
cause temporary price distortions. In addition, trading hours for foreign stock
Index Futures may not correspond perfectly to hours of trading on the foreign
exchange to which a particular foreign stock Index Future relates. This may
result in a disparity between the price of Index Futures and the value of the
relevant index due to the lack of continuous arbitrage between the Index Futures
price and the value of the underlying index.

     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.

     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. Some foreign exchanges may be principal markets so that no common
clearing facility exists and a trader may look only to the broker for
performance of the contract. 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. In addition, unless a Fund hedges against fluctuations in the
exchange rate between the U.S. dollar and the currencies in which trading is
done on foreign exchanges, any profits that a Fund might realize in trading
could be eliminated by adverse changes in the exchange rate, or the Fund could
incur losses as a result of those changes. The value of some derivative
instruments in which the Funds may 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 Sub-Adviser to forecast interest rates
and other economic factors correctly. If the Sub-Adviser incorrectly forecasts
such factors and has taken positions in derivative instruments contrary to
prevailing market trends, the Funds could be exposed to risk of loss. In
addition, a Fund's use of such instruments may cause the Fund to realize higher
amounts of short-term capital gains (generally taxed to shareholders at ordinary
income tax rates) than if the Fund had not used such instruments.

     Swap Agreements. The Tax-Efficient Equity, Structured Emerging Markets and
Tax-Efficient Structured Emerging Markets Funds may enter into equity index swap
agreements for purposes of attempting to gain exposure to the stocks making up
an index of securities in a market without actually purchasing those stocks.
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

                                     -23-
<PAGE>

parties are 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, or in a "basket" of securities representing a particular index.

     Most swap agreements entered into by the Funds 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 owing to the Fund) and any accrued but unpaid net
amounts owed to a swap counter party will be covered by segregating assets
determined to be liquid by the Adviser or a Sub-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 a 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 will depend on the Sub-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
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 counter parties that meet certain standards of
creditworthiness (generally, such counter parties would have to be eligible
counter parties under the terms of the Funds' repurchase agreement guidelines).
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.

When-Issued, Delayed Delivery and Forward Commitment Transactions

     A Fund may purchase or sell securities on a when-issued or delayed delivery
basis. These transactions involve a commitment by the Fund to purchase or sell
securities for a predetermined price or yield, with payment and delivery taking
place more than seven days in the future, or after a period longer than the
customary settlement period for that type of security. When delayed delivery
purchases are outstanding, the Fund will segregate until the settlement date
assets determined to be liquid by the Adviser or a Sub-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 purchased on
a delayed delivery basis prior to the time delivery of the securities is made,
although a Fund may earn income on segregated securities. When purchasing a
security on a delayed delivery 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 a 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
delayed delivery purchases are outstanding, the delayed delivery purchases may
result in a form of leverage. When the Fund has sold a security on a delayed
delivery basis, the Fund does not participate in future gains or losses with
respect to the security. If the other party to a delayed delivery 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 delayed delivery transaction after it is entered into, and may
sell when-issued 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 delayed delivery basis.

     Each Fund may make contracts to purchase securities for a fixed price at a
future date beyond customary settlement time ("forward commitments") if the Fund
either (i) segregates until the settlement date assets determined to be liquid
by the Adviser or a Sub-Adviser in accordance with procedures established by the
Board of Trustees in an amount sufficient to meet the purchase price or (ii)
enters into an offsetting contract for the forward sale of

                                     -24-
<PAGE>

securities of equal value that it owns. Certain Funds may enter into forward
commitments for the purchase or sale of foreign currencies. Forward commitments
may be considered securities in themselves. They involve a risk of loss if the
value of the security to be purchased declines prior to the settlement date,
which risk is in addition to the risk of decline in value of the Fund's other
assets. A Fund may dispose of a commitment prior to settlement and may realize
short-term profits or losses upon such disposition.

Warrants to Purchase Securities

     Certain Funds may invest in 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.

Repurchase Agreements

     For the purposes of maintaining liquidity and achieving income, each Fund
may enter into repurchase agreements with domestic commercial banks or
registered broker/dealers. A repurchase agreement is a contract under which a
Fund would acquire a security for a relatively short period (usually not more
than one week) subject to the obligation of the seller to repurchase and the
Fund to resell such security at a fixed time and price (representing the Fund's
cost plus interest). In the case of repurchase agreements with broker-dealers,
the value of the underlying securities (or collateral) will be at least equal at
all times to the total amount of the repurchase obligation, including the
interest factor. The Fund bears a risk of loss in the event that the other party
to a repurchase agreement defaults on its obligations and the Fund is delayed or
prevented from exercising its rights to dispose of the collateral securities.
This risk includes the risk of procedural costs or delays in addition to a loss
on the securities if their value should fall below their repurchase price. The
Adviser and the Sub-Advisers, as appropriate, will monitor the creditworthiness
of the counter parties.

Securities Loans

     Subject to certain conditions described in the Prospectuses and below, each
of the Equity Income, Value, NFJ Equity Income, NFJ Value, NFJ Value 25, Tax-
Efficient Equity, Enhanced Equity, Mega-Cap, Capital Appreciation, Mid-Cap,
Small-Cap Value, Select Growth, Growth & Income, Target, Micro-Cap, Structured
Emerging Markets and Tax-Efficient Structured Emerging Markets Funds may make
secured loans of its portfolio securities to brokers, dealers and other
financial institutions amounting to no more than 33% of its total assets, and
each of the Renaissance, Growth, Opportunity, Innovation, International, Select
International, and Global Innovation Funds may make such loans amounting to no
more than 25% of its total assets. The risks in lending portfolio securities, as
with other extensions of credit, consist of possible delay in recovery of the
securities or possible loss of rights in the collateral should the borrower fail
financially. However, such loans will be made only to broker-dealers that are
believed by the Adviser or the Sub-Advisers to be of relatively high credit
standing. Securities loans are made to broker-dealers pursuant to agreements
requiring that loans be continuously secured by collateral consisting of U.S.
Government securities, cash or cash equivalents (negotiable certificates of
deposit, bankers' acceptances or letters of credit) maintained on a daily mark-
to-market basis in an amount at least equal at all times to the market value of
the securities lent. The borrower pays to the lending Fund an amount equal to
any dividends or interest received on the securities lent. The Fund may invest
only the cash collateral received in interest-bearing, short-term securities or
receive a fee from the borrower. In the case of cash collateral, the Fund
typically pays a rebate to the lender. Although voting rights or rights to
consent with respect to the loaned securities pass to the borrower, the Fund
retains the right to call the loans and obtain the return of the securities
loaned at any time on reasonable notice, and it will do so in order that the
securities may be voted by the Fund if the holders of such securities are asked
to vote upon or consent to matters materially affecting the investment. The Fund
may also call such loans in order to sell the securities involved. Each Fund's
performance will continue to reflect changes in the value of the securities
loaned and will also reflect the receipt of either

                                     -25-
<PAGE>

interest, through investment of cash collateral by the Fund in permissible
investments, or a fee, if the collateral is U.S. Government securities.

Stocks of Small and Medium Capitalization Companies

     Certain of the Funds may invest in common stock of companies with market
capitalizations that are small compared to those of other publicly traded
companies. Generally, small market capitalization is considered to be less than
$1.5 billion and large market capitalization is considered to be more than $5
billion. Investments in larger companies present certain advantages in that such
companies generally have greater financial resources, more extensive research
and development, manufacturing, marketing and service capabilities, and more
stability and greater depth of management and technical personnel. Investments
in smaller, less seasoned companies may present greater opportunities for growth
but also may involve greater risks than customarily are associated with more
established companies. The securities of smaller companies may be subject to
more abrupt or erratic market movements than larger, more established companies.
These companies may have limited product lines, markets or financial resources,
or they may be dependent upon a limited management group. Their securities may
be traded in the over-the-counter market or on a regional exchange, or may
otherwise have limited liquidity. As a result of owning large positions in this
type of security, a Fund is subject to the additional risk of possibly having to
sell portfolio securities at disadvantageous times and prices if redemptions
require the Fund to liquidate its securities positions. In addition, it may be
prudent for a Fund with a relatively large asset size to limit the number of
relatively small positions it holds in securities having limited liquidity in
order to minimize its exposure to such risks, to minimize transaction costs, and
to maximize the benefits of research. As a consequence, as a Fund's asset size
increases, the Fund may reduce its exposure to illiquid small capitalization
securities, which could adversely affect performance.

     Many of the Funds may also invest in stocks of companies with medium market
capitalizations. Whether a U.S. issuer's market capitalization is medium is
determined by reference to the capitalization for all issuers whose equity
securities are listed on a United States national securities exchange or which
are reported on NASDAQ. Issuers with market capitalizations within the range of
capitalization of companies included in the S&P Mid Cap 400 Index may be
regarded as being issuers with medium market capitalizations. Such investments
share some of the risk characteristics of investments in stocks of companies
with small market capitalizations described above, although such companies tend
to have longer operating histories, broader product lines and greater financial
resources, and their stocks tend to be more liquid and less volatile than those
of smaller capitalization issuers.

Illiquid Securities

     Each Fund may invest in securities that are illiquid so long as no more
than 15% of the net assets of the Fund (taken at market value at the time of
investment) would be invested in such securities. Certain illiquid securities
may require pricing at fair value as determined in good faith under the
supervision of the Board of Trustees. A Sub-Adviser 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. 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
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), securities that are subject to legal or contractual
restrictions on resale (such as privately placed debt securities), and other
securities which legally or in the Adviser's or a Sub-Adviser's opinion may be
deemed illiquid (not including securities issued pursuant to Rule 144A under the
Securities Act of 1933 and certain commercial paper that the Adviser or a Sub-
Adviser has determined to be liquid under procedures approved by the Board of
Trustees).

Inflation-Indexed Bonds

     Certain Funds may invest in inflation-indexed bonds, which are fixed income
securities whose value is periodically adjusted according to the rate of
inflation. Two structures are common. The U.S. Treasury and some other issuers
utilize a structure that accrues inflation into the principal value of the bond.
Most other issuers pay out the Consumer Price Index ("CPI") accruals as part of
a semiannual coupon.

     Inflation-indexed securities issued by the U.S. Treasury have maturities of
approximately 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 the rate of inflation over the first
six months was 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 year's
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. A Fund 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
amount.

     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 the rate of inflation rises 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 increase 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.

Delayed Funding Loans and Revolving Credit Facilities

     The Funds may also 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. 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 a
time when the company's financial condition makes it unlikely that such amounts
will be repaid).

     The Funds may acquire a participation interest in delayed funding loans or
revolving credit facilities from a bank or other financial institution. See
"Loan Participations and Assignments." The terms of the participation require a
Fund to make a pro rata share of all loans extended to the borrower and entitles
a Fund to a pro rata share of all payments made by the borrower. Delayed funding
loans and revolving credit facilities usually provide for floating or variable
rates of interest. 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 or a Sub-Adviser in accordance with procedures established by the Board
of Trustees, in an amount sufficient to meet such commitments.

Catastrophe Bonds

     The Funds may invest in "catastrophe bonds." Catastrophe 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" catastrophic event,
such as a hurricane or an earthquake. 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 catastrophe 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
catastrophe 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, catastrophe bonds may also expose a
Fund to certain unanticipated risks including but not limited to issuer (credit)
default, adverse regulatory or jurisdictional interpretations and adverse tax
consequences.

     Catastrophe 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
"Characteristics and Risks of Securities and Investment Techniques--Illiquid
Securities" in the Class A, B and C, Class D and Institutional Prospectuses.
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. Catastrophe bonds are typically rated, and the Fund
will only invest in catastrophe bonds that meet the credit quality requirements
for the Fund.

Hybrid Instruments

     The Funds may invest in "hybrid" or indexed securities. 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.

                                     -28-
<PAGE>

     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-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 a Fund. Accordingly, no
Fund will invest more than 5% of its assets (taken at market value at the time
of investment) 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, a
Fund's 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.

the 300% asset coverage requirement of fundamental investment restriction (5).

     Notwithstanding any other fundamental investment restriction or policy,
each Portfolio may invest some or all of its assets in a single registered open-
end investment company or a series thereof. Unless specified above, any
fundamental investment restriction or policy of any such registered open-end
investment company or series thereof shall not be considered a fundamental
investment restriction or policy of a Portfolio investing therein.

     The investment objective of each of the Portfolios is non-fundamental and
may be changed with respect to each such Portfolio by the Trustees without
shareholder approval.

Non-Fundamental Investment Restrictions

     Each Fund (but not any Portfolio) is also subject to the following non-
fundamental restrictions and policies (which may be changed without shareholder
approval) and, unless otherwise indicated, may not:

     (1) 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 above under "Derivative
Instruments -- OTC Options"), and (e) IO/PO SMBS (as described above under
"Mortgage-Related and Asset-Backed Securities -- Stripped Mortgage - Backed
Securities") if, as a result, more than 15% of a 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);

     (2) 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 a Fund of initial or variation

                                      -33-
<PAGE>

margin in connection with futures contracts or related options transactions is
not considered the purchase of a security on margin.);

     (3) make short sales of securities or maintain a short position for the
account of a Fund unless at all times when a short position is open such Fund
owns an equal amount of such securities or owns or has the right to acquire
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;


     (4) with respect to the Renaissance, Growth, Target, Opportunity,
Innovation, International, Select International, and Global Innovation Funds,
and in each case with respect to 75% of such Fund's total assets, invest in
securities of any issuer if, immediately after such investment, more than 5% of
the total assets of such Fund (taken at current value) would be invested in the
securities of such issuer; provided that this limitation does not apply to bank
certificates of deposit or to obligations issued or guaranteed as to interest
and principal by the U.S. government or its agencies or instrumentalities;

     (5) 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 1933 Act and Section 4(2)
commercial paper) if, as a result, such investments would exceed 15% of the
value of the net assets of the relevant Fund;

     (6) write (sell) or purchase options except that each Fund may (a) write
covered call options or covered put options on securities that it is eligible to
purchase 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, and (c) each Fund may engage
in options on securities indexes, options on foreign currencies, options on
futures contracts, and options on other financial instruments or one or more
groups of instruments; provided that the premiums paid by each Fund on all
outstanding options it has purchased do not exceed 5% of its total assets. Each
Fund may enter into closing sale transactions with respect to options it has
purchased; or

     (7) invest more than 15% of the net assets of a Fund (taken at market value
at the time of the investment) in "illiquid securities," illiquid securities
being defined to include repurchase agreements maturing in more than seven days,
certain loan participation interests, fixed time deposits which are not subject
to prepayment or provide withdrawal penalties upon prepayment (other than
overnight deposits), or other securities which legally or in the Adviser's or
Sub-Adviser's opinion may be deemed illiquid (other than securities issued
pursuant to Rule 144A under the 1933 Act and certain commercial paper that the
Adviser or Sub-Adviser has determined to be liquid under procedures approved by
the Board of Trustees).

     (8) borrow money, except for temporary administrative purposes as provided
above and as provided in the fundamental investment restrictions set forth
above.

     The Trust has not adopted any non-fundamental investment restrictions or
policies for the 90/10 Portfolio, 60/40 Portfolio or 30/70 Portfolio.

     Unless otherwise indicated, all limitations applicable to a Fund's or
Portfolio's investments 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 a Fund's or Portfolio's assets invested in certain securities or
other instruments resulting from market fluctuations or other changes in a
Fund's or Portfolio's total assets will not require the Fund or Portfolio to
dispose of an investment until the Adviser or Sub-Adviser determines that it is
practicable to sell or close out the investment without undue market or tax
consequences to the Fund or Portfolio. In the event that ratings services assign
different ratings to the same security, the Adviser or Sub-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.

* Trustee is an "interested person" of the Trust (as defined in Section 2(a)(19)
of the 1940 Act).


Trustees' Compensation

     Trustees, other than those affiliated with PIMCO Advisors, a Sub-Adviser,
or Pacific Investment Management, receive an annual retainer of $47,000, plus
$2,000 for each Board of Trustees meeting attended ($1,000 if the meeting is
attended by telephone), and $1,000 for each Audit and Performance Committee
meeting attended, plus reimbursement of related expenses. Each Audit and
Performance Committee member receives an additional annual retainer of $2,000,
the Chairman of the Audit and Performance Committees receives an additional
annual retainer of $2,000, the Chairman of the Independent Trustees receives an
additional annual retainer of $6,000, and each Vice Chairman of the Independent
Trustees receives an additional annual retainer of $3,000. If in the judgment of
the Independent Trustees, it is necessary or appropriate for any Independent
Trustee, including the Chairman, to perform services in connection with
extraordinary Fund activities or circumstances, the Trustee shall be compensated
for such services at the rate of $2,000 per day, plus reimbursement of
reasonable expenses. Trustees do not currently receive any pension or retirement
benefits from the Trust or the Fund Complex (see below). The Trust has adopted a
deferred compensation plan for the Trustees, which went into place during 1997,
which permits the Trustees to defer their receipt of compensation from the
Trust, at their election, in accordance with the terms of the plan.

Investment Adviser


     PIMCO Advisors serves as investment adviser to each of the Funds and
Portfolios pursuant to an investment advisory agreement ("Advisory Agreement")
between PIMCO Advisors and the Trust. PIMCO Advisors was organized as a limited
partnership under Delaware law in 1987. PIMCO Advisors sole general partner is
Pacific-Allianz Partners LLC. Pacific-Allianz Partners LLC is a Delaware limited
liability company with two members, Allianz GP Sub LLC, a Delaware limited
liability company, and Pacific Asset Management LLC, a Delaware limited
liability company. Allianz GP Sub LLC is a wholly-owned subsidiary of Allianz of
America, Inc., which is a wholly-owned subsidiary of Allianz AG. Pacific Asset
Management LLC is a wholly-owned subsidiary of Pacific Life Insurance Company,
which is a wholly-owned subsidiary of Pacific Mutual Holding Company.

     The general partner of PIMCO Advisors has substantially delegated its
management and control of PIMCO Advisors to an Executive Committee.  The
Executive Committee of PIMCO Advisors is comprised of Joachim Faber, Udo Frank,
Kenneth M. Poovey, William S. Thompson, Jr. and Marcus Riess.


     PIMCO Advisors is located at 800 Newport Center Drive, Newport Beach,
California 92660. PIMCO Advisors and its subsidiary partnerships had
approximately $272 billion of assets under management as of


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

     /1/ The amounts listed in column (3) include total compensation paid to the
Trustees for their services as Trustees of the Trust (for all Trustees) and
Pacific Select Fund (for Messrs. Nelson, Porter, and Richards) for the twelve-
month period ended June 30, 2000. As of May 16, 2000, Mr. Cannon also began
serving as Trustee of PIMS, PVIT, and PCM and received compensation for the
period ended June 30, 2000. By virtue of having PIMCO Advisors or an affiliate
of PIMCO Advisors as investment adviser, the Trust, PIMS, PVIT, PCM and Pacific
Select Fund were considered to be part of the same "Fund Complex" for these
purposes.

     /2/ The Trust has adopted a deferred compensation plan (the "Plan") which
went into place during fiscal 1997. Of the amounts listed in column (2), the
following Trustees elected to have the following amounts deferred from the Trust
and all investment companies in the Fund Complex, respectively: Cannon -
$65,000, $84,250; Porter - $65,000, $65,000; and Thorne - $65,000, $65,000.

     /3/ Mr. Segall retired as a Trustee in December 1999.

Agreement with Allianz AG
-------------------------

     On May 5, 2000 the general partners of PIMCO Advisors closed the
transactions contemplated by the Implementation and Merger Agreement dated as of
October 31, 1999 ("Implementation Agreement"), as amended March 3, 2000, with
Allianz of America, Inc., Pacific Asset Management LLC, PIMCO Partners, LLC,
PIMCO Holding LLC, PIMCO Partners, G.P., and other parties to the Implementation
Agreement. As a result of completing these transactions, PIMCO Advisors is now
majority-owned indirectly by Allianz AG, with subsidiaries of Pacific Life
Insurance Company retaining a significant minority interest. Allianz AG is a
German based insurer. Pacific Life Insurance Company is a Newport Beach,
California based insurer.

     In connection with the closing, Allianz of America entered into a put/call
arrangement for the possible disposition of Pacific Life's indirect interest in
PIMCO Advisors. The put option held by Pacific Life will allow it to require
Allianz of America, on the last business day of each calendar quarter following
the closing, to purchase at a formula-based price all of the PIMCO Advisors'
units owned directly or indirectly by Pacific Life. The call option held by
Allianz of America will allow it, beginning January 31, 2003 or upon a change in
control of Pacific Life, to require Pacific Life to sell or cause to be sold to
Allianz of America, at the same formula-based price, all of the PIMCO Advisors'
units owned directly or indirectly by Pacific Life.


     Allianz AG's address is Koniginstrasse 28, D-80802, Munich, Germany.
Pacific Life's address is 700 Newport Center Drive, Newport Beach, CA 92660.

Advisory Agreement
------------------


     PIMCO Advisors, subject to the supervision of the Board of Trustees, is
responsible for providing advice and guidance with respect to the Funds and
Portfolios and for managing, either directly or through others selected by the
Adviser, the investments of the Funds and Portfolios. PIMCO Advisors also
furnishes to the Board of Trustees periodic reports on the investment
performance of each Fund and Portfolio. As more fully discussed below, for all
of the Funds except the Equity Income, Value, Growth, Target, Opportunity,
Innovation, Global Innovation, Renaissance, International, Select Growth, and
Growth & Income Funds, PIMCO Advisors has engaged affiliates to serve as Sub-
Advisers. PIMCO Advisors has engaged an unaffiliated firm to serve as Sub-
Adviser to the International Fund. The PIMCO Equity Advisors division ("PIMCO
Equity Advisors") of PIMCO Advisors manages the investment portfolios of the
Equity Income, Value, Growth, Target, Opportunity, Innovation, Global
Innovation, Renaissance, Select Growth,and Growth & Income Funds. Acting in this
capacity, PIMCO Equity Advisors is also referred to herein as a "Sub- Adviser."
If a Sub-Adviser ceases to manage the portfolio of a Fund, PIMCO Advisors will
either assume full responsibility for the management of that Fund, or retain a
new Sub-Adviser subject to the approval of the Trustees and, if required, the
Fund's shareholders.

     PIMCO Advisors selects the Underlying Funds in which the 90/10 Portfolio,
the 60/40 Portfolio and the 30/70 Portfolio invest. PIMCO Advisors' Asset
Allocation Committee is responsible for determining how the assets of the
Portfolios are allocated and reallocated from time to time among the Underlying
PIMCO Funds selected by PIMCO Advisors. The Portfolios do not pay any fees to
PIMCO Advisors in return for these services under the Advisory Agreement. The
Portfolios do, however, indirectly pay a proportionate share of the advisory
fees paid to PIMCO Advisors and Pacific Investment Management by the Underlying
PIMCO Funds in which the Portfolios invest.

     Under the terms of the Advisory Agreement, PIMCO Advisors is obligated to
manage the Funds and the Portfolios in accordance with applicable laws and
regulations. The investment advisory services of PIMCO Advisors to the Trust are
not exclusive under the terms of the Advisory Agreement. PIMCO Advisors is free
to, and does, render investment advisory services to others.

                                      -40-
<PAGE>

     The Advisory Agreement will continue in effect with respect to a Fund and
Portfolio for two years from its effective date, and thereafter on a yearly
basis, provided such continuance is approved annually (i) by the holders of a
majority of the outstanding voting securities of the Fund or Portfolio, or by
the Board of Trustees, and (ii) by 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 Advisory Agreement. The Advisory
Agreement may be terminated without penalty by vote of the Trustees or the vote
of a majority of the outstanding voting shares of the Trust (or with respect to
a particular Fund or Portfolio, by the vote of a majority of the outstanding
voting shares of such Fund or Portfolio), or by the Adviser, on 60 days' written
notice to the other party and will terminate automatically in the event of its
assignment. In addition, the Advisory Agreement may be terminated with regard to
the Renaissance, Growth, Target, Opportunity, Innovation and International Funds
by vote of a majority of the Trustees who are not interested persons of the
Trust, on 60 days' written notice to PIMCO Advisors.

     The Adviser currently receives a monthly investment advisory fee from each
Fund at the following annual rates (based on the average daily net assets of the
particular Funds):

Portfolio Management Agreements


    PIMCO Equity Advisors manages the investment portfolios of the Growth,
Target, Opportunity, Innovation, Renaissance, Select Growth, Equity Income,
Value, and Growth & Income Funds. The Adviser employs Sub-Advisers to provide
investment advisory services to each other Fund pursuant to portfolio management
agreements (each a "Portfolio Management Agreement") between the Adviser and the
Fund's Sub-Adviser. Each Sub-Adviser retained by the Adviser is an affiliate of
the Adviser except for Blairlogie Capital Management ("Blairlogie"), which
advises the International Fund. The Adviser currently has eight subsidiaries,
the following four of which manage one or more of the Funds: PIMCO/Allianz
Investment Advisors LLC ("PAIA"), Parametric Portfolio Associates
("Parametric"), Cadence Capital Management ("Cadence") and NFJ Investment Group
("NFJ"). On April 30, 1999, the Adviser sold all of its ownership interest in

    Shareholders of each Fund (except the Innovation, Mid-Cap and Micro-Cap
Funds) have approved a proposal permitting PIMCO Advisors to enter into new or
amended sub-advisory agreements with one or more sub-advisers with respect to
each Fund without obtaining shareholder approval of such agreements, subject to
the conditions of an exemptive order that has been granted by the Securities and
Exchange Commission. One of the conditions requires the Board of Trustees to
approve any such agreement. In addition, the exemptive order prohibits PIMCO
Advisors from entering into sub-advisory agreements with affiliates of PIMCO
Advisors without shareholder approval, unless such affiliates are substantially
wholly-owned by PIMCO Advisors.

* The Administrator receives administrative fees based on a Fund's or
Portfolio's average daily net assets attributable in the aggregate to its
Institutional and Administrative Class shares on the one hand, and to its Class
A, Class B and Class C shares on the other.

** As described below, the Administration Agreement includes a plan adopted in
conformity with 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.

*** The Administrative Fee for Institutional and Administrative Class shares of
each Portfolio reflects a fee waiver currently in effect. In the absence of this
waiver, the Administrative Fee rate for Institutional and Administrative Class
shares of each Portfolio would be 0.15% per annum.

(1) The Administrator has contractually agreed to waive, reduce or reimburse its
Administrative Fee for each class of shares for each of these Funds in an amount
that, in essence, is equal to such Fund's organizational expenses and
disinterested Trustees' expenses (as defined below) attributed to that class.


     Except for the expenses paid by the Administrator, the Trust bears all
costs of its operations. The Trust is responsible for the following expenses:
(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
Advisors, Pacific Investment Management, or their 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 Advisors, any Sub-Adviser, or the Trust, and any counsel
retained exclusively for their benefit ("disinterested Trustees' expenses");
(vi) extraordinary expenses, including costs of litigation and indemnification
expenses; (vii) expenses which are capitalized in accordance with generally
accepted accounting principals; and (viii) any expenses allocated or allocable
to a specific class of shares ("Class-specific expenses").

     Class-specific expenses include distribution and/or service fees payable
with respect to the Class A, Class B, Class C, Class D or Administrative Class
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 (the
"Multi-Class Plan") adopted pursuant to Rule 18f-3 under the 1940 Act, which is
subject to review and approval by the Trustees. It is not presently anticipated
that any expenses other than distribution and/or service fees and administrative
fees will be allocated on a class-specific basis.

     The Administration Agreement may be terminated by the Trust at any time by
vote of (1) a majority of the Trustees, (2) a majority of the outstanding voting
securities of the Trust, or (3) with respect to the Renaissance, Growth, Target,
Opportunity, Innovation and International Funds, by a majority of the Trustees
who are not interested persons of the Trust or PIMCO Advisors, on 60 days'
written notice to PIMCO Advisors.

     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 purchased
through such firms). The Administration Agreement includes a plan specific to
Class D shares which 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

                                      -48-

payments may be made are services in connection with the distribution of Class D
shares and/or the provision of shareholder services. See "Distribution of Trust
Shares--Plan for Class D Shares."

     After an initial two-year term, the Sub-Administration Agreement will
continue from year to year upon the approval of the parties thereto. The Sub-
Administration Agreement may be terminated at any time by PIMCO Advisors or
Pacific Investment Management upon 60 days' written notice to the other party
and, with respect to the services rendered to the Trust, at any time by vote of
a majority of the disinterested Trustees of the Trust. The Sub-Administration
Agreement will also terminate upon termination of the Administration Agreement.

     For the fiscal years ended June 30, 2000, June 30, 1999 and June 30, 1998,
the aggregate amount of the administration fees paid by the Funds and Portfolios
was as follows (Class D shares were not offered prior to April 8, 1998):

                                          Year             Year            Year

                         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 (the "Distribution Contract") with the Trust. 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, Portfolio or class of shares without penalty, at any
time, by the Fund, Portfolio 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 Portfolio, 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 entire Board of Trustees or by the majority of the
outstanding shares of the Fund, Portfolio or class, and (ii) by a majority of
the Trustees who are not interested persons (as defined in the 1940 Act) of the
Trust and who have no direct or indirect interest financial interest in the
Distribution Contract or the Distribution and/or Servicing Plans described
below, by vote cast in person at a meeting called for the purpose. If the
Distribution Contract is terminated (or not renewed) with respect to one or more
Funds, Portfolios or classes, it may continue in effect with respect to any
Fund, Portfolio or class as to which it has not been terminated (or has been
renewed).

     The Trust currently offers up to six classes of shares of each of the
Funds: Class A, Class B, Class C, Class D, Institutional Class and
Administrative Class shares. The Trust currently offers Class A, Class B, Class
C, Institutional Class and Administrative Class shares of each Portfolio.

     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 advisers, with which the
Distributor has an agreement for the use of PIMCO Funds: Multi-Manager 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 customers' investments in the Funds). Administrative Class shares
are offered primarily through employee benefit plan 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.

                                      -50-
<PAGE>

     Under the Trust's Multi-Class Plan, shares of each class of each Fund and
Portfolio represent an equal pro rata interest in the Fund or Portfolio 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 has exclusive voting rights on any matter submitted to shareholders that
relates solely to its distribution or service arrangements; and (c) 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. 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 and the Retail Portfolio
Prospectus under the caption "Investment Options (Class A, B and C Shares)," a
contingent deferred sales charge is imposed upon certain redemptions of 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 series-
by-series basis, shareholders should consider whether to exchange shares of one
Fund or Portfolio for shares of another Fund or Portfolio prior to redeeming an
investment if such an exchange would reduce the contingent deferred sales charge
applicable to such redemption.

     During the fiscal years ended June 30, 2000, June 30, 1999 and June 30,
1998, 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 and the Portfolios:

             Year        Year        Year
             Ended       Ended       Ended
Class        6/30/00     6/30/99     6/30/98
---------  ----------  ----------  ----------

Class A    $  171,399  $    5,341  $  2,273

Class B     2,328,986   2,063,747   945,353

Class C       612,618     618,030   480,061

     As described in the Class A, B and C Prospectus and the Retail Portfolio
Prospectus under the caption "Investment Options (Class A, B and C Shares),"
Class A shares of the Trust are sold pursuant to an initial sales charge, which
declines as the amount of the purchase reaches certain defined levels. For the
fiscal years ended June 30, 2000, June 30, 1999 and June 30, 1998, the
Distributor received an aggregate of $16,118,114, $7,013,745 and $4,878,434,
respectively, and retained an aggregate of $2,703,541, $904,586 and $506,878,
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 Class A, B and C Prospectus and the Retail Portfolio
Prospectus under the caption "Investment Options -- Class A, B and C Shares --
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"), the Distributor receives (i) in
connection with the distribution of Class B and Class C shares of the Trust,
certain distribution fees from the Trust, and (ii) in connection with personal
services rendered to Class A, Class B and Class C shareholders of the Trust and
the maintenance of shareholder accounts, 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.

     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 the Distribution Agreement, with respect to each Fund's or
Portfolio'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.

Class A Servicing Fees
----------------------

     As compensation for services rendered and expenses borne by the Distributor
in connection with personal services rendered to Class A shareholders of the
Trust and the maintenance of Class A shareholder accounts, the Trust pays the
Distributor servicing fees up to the annual rate of .25% (calculated as a
percentage of each Fund's or Portfolio's average daily net assets attributable
to Class A shares).

Class B and Class C Distribution and Servicing Fees
---------------------------------------------------

     As compensation for services rendered and expenses borne by the Distributor
in connection with the distribution of Class B and Class C shares of the Trust,
and in connection with personal services rendered to Class B and Class C
shareholders of the Trust and the maintenance of Class B and Class C shareholder
accounts, the Trust pays the Distributor servicing and distribution fees up to
the annual rates set forth below (calculated as a percentage of each Fund's or
Portfolio's average daily net assets attributable to Class B and Class C shares,
respectively):


                                      Servicing        Distribution
                                         Fee                Fee
                                     -----------        ----------
          All Funds and Portfolios     .25%                .75%

                                      -52-
<PAGE>

     The Retail Plans were adopted pursuant to Rule 12b-1 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 distributions of sales
literature. The servicing fee, which is 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 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 or Portfolio'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 or
Portfolio may indirectly support sales and servicing efforts relating to the
other Funds' or Portfolios' 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 or Portfolio's shares, and
allocates other expenses among the Funds or Portfolios based on their relative
net assets. Expenses allocated to each Fund or Portfolio 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:

All Funds and Portfolios/(1)/
                                       Servicing   Distribution
                                          Fee           Fee
                                       ----------  -------------

Class A                                      .25%        N/A
Class B /(2)/                                .25%       None
Class C (purchased before July 1,            .25%       None
1991)
Class C/(3)/ (purchased on or after          .25%       .65%
July 1, 1991)

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 transactions 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.

                                      -53-
<PAGE>

     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 or Portfolios. 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 or Portfolio and/or all
of the Funds or Portfolios 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. In its
capacity as administrator for the Funds and Portfolios, PIMCO Advisors may 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 such 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 or Portfolio 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 Retail Plan Trustees"), or by vote of a
majority of the outstanding voting securities of the relevant class of that Fund
or Portfolio. Any change in any Retail Plan that would materially increase the
cost to the class of shares of any Fund or Portfolio to which the Plan relates
requires approval by the affected class of shareholders of that Fund or
Portfolio. 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 Trustees, including a majority of the disinterested
Retail Plan 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
Portfolio, 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 Retail Plan Trustees and (ii) by the vote of a
majority of the entire Board of Trustees cast in person at a meeting called for
the purpose of voting on such approval.

     If a Retail Plan is terminated (or not renewed) with respect to one or more
Funds or Portfolios, or classes thereof, it may continue in effect with respect
to any class of any Fund or Portfolio 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. In this regard, 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 expenses of the Funds and Portfolios are
essentially fixed, the Trustees believe that the effect of the Retail Plans on
sales and/or redemptions may benefit the Trust by reducing expense ratios and/or
by affording greater flexibility to the Sub-Advisers. From time to time,
expenses of the Distributor incurred in connection with the sale of Class B and
Class C shares of the Trust, and in connection with the servicing of Class B and
Class C shareholders 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 and Portfolios to continue payments of distribution and
servicing fees in the future with respect to Class B and Class C shares.

Information for information about these Funds.

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 or Portfolio, 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: 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; and performing
similar account administrative services.

The same entity may be the recipient of fees under both the Administrative
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 increase
materially 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 ("disinterested Administrative 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.

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 Administrative Plan Trustees. The Administrative 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 Administrative Plan Trustees. 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 than 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 Administrative 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 and/or distribution 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 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.

The Administrative Plans were not in effect in prior fiscal years.

Plan for Class D Shares

     As described above under "Management of the Trust--Fund Administrator," the
Trust's Administration Agreement includes a plan (the "Class D Plan") adopted in
conformity with 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 advisers ("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 Class D
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 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.

                                      -64-

     The Administrator has entered into an agreement with the Distributor under
which the Distributor is compensated for providing or procuring certain of the
Special Class D Services at the rate of 0.25% 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 provided 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
0.25% 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 the 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 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 only 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
expense 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.


     For the fiscal years ended June 30, 2000, June 30, 1999 and June 30, 1998,
the Trust paid qualified service providers an aggregate of $120,680, $22,580 and
$353, respectively, pursuant to the Class D Plan. Such payments were allocated
among the Funds as follows:

     The Portfolios do not offer Class D shares.

Purchases, Exchanges and Redemptions

     Purchases, exchanges and redemptions of the Trust's shares are discussed in
the Class A, B and C Prospectus, the Class D Prospectus and the Retail Portfolio
Prospectus under the headings "Investment Options--Class A, B and C Shares" and
"How to Buy and Sell Shares," and in the Institutional Prospectus and the
Institutional Portfolio Prospectus under the headings ""Investment Options--
Institutional Class and Administrative Class Shares" and "Purchases, Redemptions
& Exchanges."

     Certain clients of the Adviser or a Sub-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.

     One or more classes of shares of the Funds and Portfolios may not be
qualified or registered for sale in all States. Prospective investors should
inquire as to whether shares of a particular Fund or Portfolio, or class of
shares thereof, are available for offer and sale in their State of domicile or
residence. Shares of a Fund or Portfolio 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.


     As described and subject to any limits in the Class A, B and C Prospectus,
the Class D Prospectus and the Retail Portfolio Prospectus under the caption
"How to Buy and Sell Shares--Exchanging Shares," and in the Institutional
Prospectus and the Institutional Portfolio Prospectus under the caption
"Purchases, Redemptions and Exchanges--Exchange Privilege," a shareholder may
exchange shares of any Fund or Portfolio for shares of the same class of any
other Fund or Portfolio of the Trust that is available for investment, or any
series of PIMS, 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 or
Portfolio. For example, if a shareholder invests in 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 and the Retail Portfolio Prospectus
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, 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 or Portfolio


                                      -66-
<PAGE>

from which the exchange was made. For federal income tax purposes, an exchange
is treated as a sale of shares and generally results in a capital gain or loss.

     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 New York Stock 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 year. For example, the Trust currently 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 or
Portfolio, subsequently exchanges those shares for shares of a different Fund or
Portfolio and then exchanges back into the originally purchased Fund or
Portfolio. 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 or Portfolio) 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 as described in the Prospectuses.

     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 or Portfolios 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 payments for more than seven days, as permitted by law.

     The Trust is committed to paying in cash all requests for redemptions by
any shareholder of record of the Funds and Portfolios, 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
redeem amounts in excess of the lesser of (i) or (ii) above by payment in kind
of securities held by the particular Fund or Portfolio. When shares are redeemed
in kind, the redeeming shareholder should expect to incur transaction costs upon
the disposition of the securities received in the distribution.

     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 set forth in the applicable
Prospectus or in the Guide. An investor will be notified that the value of the
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 Trust's Agreement and Declaration of Trust, as amended and
restated (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 Funds and Portfolios may also charge periodic account fees for
accounts that fall below minimum balances as described in the Prospectuses.

Fund Reimbursement Fees

     Investors in Institutional Class and Administrative Class shares of the
Structured Emerging Markets and Tax-Efficient Structured Emerging Markets Funds
are subject to a fee (a "Fund Reimbursement Fee"), both at the time of purchase
and at the time of redemption, equal to 1.00% of the net asset value of the
shares purchased or redeemed. Fund Reimbursement Fees are deducted automatically
from the amount invested or the amount to be received in connection with a
redemption; the fees are not paid separately. Fund Reimbursement Fees are paid
to

                                      -67-
<PAGE>

and retained by the Funds to defray certain costs described below and no portion
of such fees are paid to or retained by the Adviser, the Distributor or the
Sub-Adviser. Fund Reimbursement Fees are not sales loads or contingent deferred
sales charges. Reinvestment of dividends and capital gains distributions paid to
shareholders by the Funds are not subject to Fund Reimbursement Fees, but
redemptions of shares acquired by such reinvestments are subject to Fund
Reimbursement Fees.

     The purpose of Fund Reimbursement Fees is to defray the costs associated
with investing the proceeds of the sale of shares to investors (in the case of
purchases) or the costs associated with the sale of portfolio securities to
satisfy redemption requests (in the case of redemptions), thus insulating
existing shareholders from such costs. The amount of a Fund Reimbursement Fee
represents the Sub-Adviser's estimate of the costs reasonably anticipated to be
incurred by the Funds in connection with the purchase or sale of portfolio
securities, including international stocks, associated with an investor's
purchase or redemption proceeds. These costs include brokerage costs, market
impact costs (i.e., the increase in market prices which may result when a Fund
purchases or sells thinly traded stocks), and the effect of "bid/asked" spreads
in international markets. Transaction costs incurred when purchasing or selling
stocks of companies in foreign countries, and particularly emerging market
countries, may be significantly higher than those in more developed countries.
This is due, in part, to less competition among brokers, underutilization of
technology on the part of foreign exchanges and brokers, the lack of less
expensive investment options (such as derivative instruments) and lower levels
of liquidity in foreign and underdeveloped markets.

     On July 1, 1998, the Structured Emerging Markets and Tax-Efficient
Structured Emerging Markets Funds commenced investment operations immediately
following a transaction (the "Parametric Transaction") in which each Fund issued
Institutional Class shares to unit holders of the Parametric Portfolio
Associates Emerging Markets Trust, a separate account managed by Parametric (the
"EM Trust"), in exchange for the EM Trust's assets. The EM Trust's unit holders
were divided into two categories: participants who pay taxes ("Taxable
Participants") and participants that are non-taxable entities ("Non-Taxable
Participants" and, together with the Taxable Participants, the "Participants").
Assets in the EM Trust equal in value to the value of the Taxable Participants'
participation in the EM Trust were transferred to the Tax- Efficient Structured
Emerging Markets Fund in exchange for Institutional Class shares of that Fund.
Assets in the EM Trust equal in value to the value of the Non-Taxable
Participants' participation in the EM Trust were transferred to the Structured
Emerging Markets Fund in exchange for Institutional Class shares of that Fund.
The Participants' interests in the EM Trust were then terminated and
Institutional Class shares of the Tax-Efficient Structured Emerging Markets Fund
were distributed to the Taxable Participants and Institutional Class shares of
the Structured Emerging Markets Fund were distributed to the Non-Taxable
Participants, in each case in proportion to each Participant's interest in the
EM Trust. After the completion of the Parametric Transaction, the portfolio
securities which were owned by the EM Trust became portfolio securities of the
Funds (allocated to the Funds on a substantially pro-rata basis), to be held or
sold as Parametric deems appropriate.

     Portfolio securities transferred to the Funds pursuant to the Parametric
Transaction will have the same tax basis as they had when held by the EM Trust.
Such securities have "built-in" capital gains if their market value at the time
of the Parametric Transaction was greater than their tax basis (other securities
may have "built-in" capital losses for tax purposes if their market value at the
time of the Parametric Transaction was less than their tax basis). Built-in
capital gains realized upon the disposition of these securities will be
distributed to all Fund shareholders who are shareholders of record on the
record date for the distribution, even if such shareholders were not
Participants in the EM Trust prior to the Parametric Transaction. This means
that investors purchasing Fund shares after the date of this Prospectus may be
required to pay taxes on distributions that economically represent a return of a
portion of the amount invested. For further information, see "Taxation--
Distributions" below.

     In connection with the Parametric Transaction, the Participants in the EM
Trust will not be subject to Fund Reimbursement Fees with respect to any shares
of these Funds they acquired through June 30, 1998, and will not be subject to
Fund Reimbursement Fees upon the subsequent redemption (including any redemption
in connection with an exchange) of any shares acquired by any such Participant
through June 30, 1998. Such

                                      -68-
<PAGE>

Participants will be subject to such Fund Reimbursement Fees to the same extent
as any other shareholder on any shares of either Fund acquired (whether by
reinvestment of dividends or capital gain distributions or otherwise) after June
30, 1998.


                      PORTFOLIO TRANSACTIONS AND BROKERAGE

Investment Decisions and Portfolio Transactions

     Investment decisions for the Trust and for the other investment advisory
clients of the Adviser and Sub-Advisers 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 investment by the Funds
may also be appropriate for other clients served by the Adviser or a Sub-
Adviser. Thus, a particular security may be bought or sold for certain clients
even 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 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 or Sub-
Adviser. Particularly when investing in less liquid or illiquid securities of
smaller capitalization companies, such allocation may take into account the
asset size of a Fund in determining whether the allocation of an investment is
suitable. As a result, larger Funds may become more concentrated in more liquid
securities than smaller Funds or private accounts of the Adviser or a Sub-
Adviser pursuing a small capitalization investment strategy, which could
adversely affect performance. The Adviser or a Sub-Adviser may aggregate orders
for the Funds with simultaneous transactions entered into on behalf of its other
clients so long as price and transaction expenses are averaged either for the
portfolio transaction or for that 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 or the Sub-
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 trans actions 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 and/or each Sub-Adviser places orders for the purchase and sale
of portfolio securities, options and futures contracts 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 or Sub-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 or Sub-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. Because the Portfolios invest
exclusively in Institutional Class shares of

                                      -69-
<PAGE>

Underlying PIMCO Funds, they generally do not pay brokerage commissions and
related costs, but do indirectly bear a proportionate share of these costs
incurred by the Underlying PIMCO Funds in which they invest.

(1) Please see the section captioned "The Trust" in this Statement of Additional
Information for information about these Funds.



     The Adviser or, pursuant to the portfolio management agreements, a Sub-
Adviser, places orders for the purchase and sale of portfolio investments for a
Fund's accounts with brokers or dealers selected by it in its discretion. In
effecting purchases and sales of portfolio securities for the accounts of the
Funds, the Adviser and

                                      -70-
<PAGE>

the Sub-Advisers 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 or Sub-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 and Sub-Advisers 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 and Sub-Advisers receive research services from many broker-dealers
with which the Adviser and Sub-Advisers place the Trust's portfolio
transactions. 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, evaluations of securities and recommendations as
to the purchase and sale of securities. Some of these services are of value to
the Adviser and Sub-Advisers in advising various of their clients (including the
Trust), although not all of these services are necessarily useful and of value
in managing the Trust. The advisory fees paid by the Trust are not reduced
because the Adviser and Sub-Advisers receive such services.

     In reliance on the "safe harbor" provided by Section 28(e) of the
Securities Exchange Act of 1934, as amended (the "1934 Act"), the Adviser and
Sub-Advisers may cause the Trust to pay broker-dealers which provide them with
"brokerage and research services" (as defined in the 1934 Act) an amount of
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 or Sub-Advisers 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.

     The Adviser or a Sub-Adviser may place orders for the purchase and sale of
exchange-listed portfolio securities with a broker-dealer that is an affiliate
of the Adviser or Sub-Adviser where, in the judgment of the Adviser or Sub-
Adviser, such firm will be able to obtain a price and execution at least as
favorable as other qualified broker-dealers.


     Pursuant to rules of the SEC, a broker-dealer that is an affiliate of the
Adviser or a Sub-Adviser may receive and retain compensation for effecting
portfolio transactions for a Fund on a securities exchange if the commissions
paid to such an affiliated broker-dealer by a Fund on exchange transactions do
not exceed "usual and customary brokerage commissions." The rules define "usual
and customary" commissions to include amounts which are "reasonable and fair
compared to the commission, fee or other remuneration received or to be received
by other brokers in connection with comparable transactions involving similar
securities being purchased or sold on a securities exchange during a comparable
period of time." As required by applicable SEC rules, the Board of Trustees has
adopted procedures which are reasonably designed to provide that any
commissions, fees or other remuneration paid to an affiliated broker are
consistent with the foregoing standards.

Portfolio Turnover

     A change in the securities held by a Fund is known as "portfolio turnover."
With the exception of the Tax-Efficient Structured Emerging Markets and
Tax-Efficient Equity Funds (which may attempt to minimize portfolio turnover as
a tax-efficient management strategy), the Sub-Advisers manage the Funds without
regard generally to restrictions on portfolio turnover. The use of futures
contracts and other 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

                                      -71-
<PAGE>

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).
To the extent portfolio turnover results in the realization of net short-term
capital gains, such gains are generally taxed to shareholders at ordinary income
tax rates. See "Taxation."

     The portfolio turnover rate of a Fund or Portfolio 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 or Portfolio 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.

     Because the Adviser does not expect to reallocate the Portfolio's assets
among the Underlying Funds on a frequent basis, the portfolio turnover rates for
the Portfolios are expected to be modest (i.e., less than 25%) in comparison to
most mutual funds. However, the Portfolios indirectly bear the expenses
associated with the portfolio turnover of the Underlying Funds, a number of
which have high (i.e., greater than 100%) portfolio turnover rates.


     Portfolio turnover rates for each Fund for which financial highlights are
available are provided under "Financial Highlights" in the applicable
Prospectus. In connection with the change in Sub-Advisers of the Equity Income,
Value, Growth, Target, Opportunity, Innovation, Renaissance, Select Growth,
Growth & Income and Select International Funds, these Funds may experience
increased turnover due to the differences, if any, between the portfolio
management strategies of the particular Fund's current Sub-Adviser and previous
sub-adviser. See "Management of the Trust--Portfolio Management Agreements."



                                 NET ASSET VALUE

     As indicated in the Prospectuses under the heading "How Fund Shares are
Priced," the net asset value ("NAV") of a class of a Fund's or Portfolio's
shares is determined by dividing the total value of a Fund's or Portfolio'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 the 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 quotes are not readily available may be
valued, pursuant to guidelines established by the Board of Trustees, with
reference to other securities or 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. In particular, calculation of the NAV of the Select International,
Structured Emerging Markets, Tax-Efficient Structured Emerging Markets, Global
Innovation and International Funds may not take place contemporaneously with the
determination of the prices of foreign securities used in NAV calculations.

                                      -72-
<PAGE>

     Fund and Portfolio 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 their agents after the NAV has been calculated on a particular day
will not generally be used to retroactively adjust the price of the 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 or their designees, pursuant
to procedures approved by the Board of Trustees. Fair valuation may also be used
by the Board of Trustees if extraordinary events occur after the close of the
relevant market but prior to the NYSE Close.

     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 classes of shares of the Funds
and Portfolios with higher service and/or distribution fees applicable to such
shares may be lower than the per share net asset value of the classes of shares
with lower or no service and/or distribution fees as a result of the higher
daily expense accruals of the service and/or distribution fees applicable to
such classes. Generally, for Funds and Portfolios 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 or Portfolio's
classes.

     The Trust expects that the holidays upon which the Exchange will be closed
are as follows: 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.


                                    TAXATION

     The following discussion is general in nature and should not be regarded as
an exhaustive presentation of all possible tax ramifications. All shareholders
should consult a qualified tax adviser regarding their investment in a Fund or
Portfolio.

     Each Fund and Portfolio intends to qualify annually and elect to be treated
as a regulated investment company under Subchapter M of the Internal Revenue
Code of 1986, as amended (the "Code"). To qualify as a regulated investment
company, each Fund and Portfolio 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
(including but not limited to gains from options, futures or forward contracts)
derived with respect to its business of investing in such stock, securities or
currencies ("Qualifying Income Test") and (b) diversify its holdings so that, at
the end of each quarter of the taxable year, (i) at least 50% of the value of
the Fund's or Portfolio's total assets is represented by cash, cash items
(including receivables), U.S. Government securities, 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 or Portfolio'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 (other than U.S.
Government securities or the securities of other regulated investment companies)
of any one issuer or of two or more issuers which the Fund or Portfolio controls
and which are engaged in the same, similar or related trades or businesses. In
order to qualify for the special tax treatment accorded regulated investment
companies, each Fund and Portfolio must distribute each taxable year an amount
at

                                      -73-
<PAGE>

least equal to the sum of (i) 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. For purposes of the Qualifying Income Test,
the Treasury Department is authorized to promulgate regulations under which
gains from foreign currencies (and options, futures, and forward contracts on
foreign currency) would not constitute qualifying income if such gains are not
directly related to investing in securities (or options and futures with respect
to stock or securities). To date, such regulations have not been issued.




Distributions


     As a regulated investment company, each Fund and Portfolio generally will
not be subject to U.S. federal income tax on its investment company taxable
income and net capital gains (that is, 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 or Portfolio as capital gain dividends, if
any, that it distributes to shareholders on a timely basis. Each Fund and
Portfolio intends to distribute to its shareholders, at least annually,
substantially all of its investment company taxable income and any net capital
gains. Amounts not distributed by a Fund or Portfolio on a timely basis in
accordance with a calendar year distribution requirement are subject to a
nondeductible 4% excise tax. To avoid the tax, each Fund and Portfolio must
distribute during each calendar year an amount at least equal to the sum of (1)
98% of its ordinary income (not taking into account any capital gains or losses)
for the calendar year, (2) 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 of the calendar year, 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 or Portfolio in October, November or December of that year
to shareholders of record on a date in such a month and paid by the Fund or
Portfolio during January of the following year.


     Shareholders subject to U.S. federal income tax will be subject to tax on
dividends received from a Fund or Portfolio, regardless of whether received in
cash or reinvested in additional shares. Such distributions will be taxable to
shareholders in the calendar year in which the distributions are declared,
rather than the calendar year in which the distributions are received.
Distributions received by tax-exempt shareholders generally will not be subject
to federal income tax to the extent permitted under applicable tax law.


     All shareholders must treat dividends, other than capital gain dividends,
exempt-interest dividends, if any, and dividends that represent a return of
capital to shareholders, as ordinary income. In particular, distributions
derived from short-term gains will be treated as ordinary income. Dividends, if
any, derived from interest on certain U.S. Government securities may be exempt
from state and local taxes, although interest on mortgage-backed U.S. Government
securities is generally not so exempt. While the Tax-Efficient Equity and Tax-
Efficient Structured Emerging Markets Funds seek to minimize taxable
distributions, the Funds may be expected to earn and distribute taxable income
and may also be expected to realize and distribute capital gains from time to
time. Each Fund will advise shareholders annually of the amount and nature of
the dividends paid to them. The tax status of each Fund and Portfolio and the
distributions which it may make are summarized in the Prospectuses under the
captions "Fund Distributions" (or "Portfolio Distributions") and "Tax
Consequences."

     A portion of the dividends paid by Funds that invest in stock of U.S.
corporations may qualify for the deduction for dividends received by
corporations (subject generally to a 46-day holding period requirement).
Dividends paid by the other Funds generally are not expected to qualify for the
deduction for dividends received by corporations.

     Distributions of net capital gains, if any, designated as capital gain
dividends, are taxable as long-term capital gains (generally subject to a 20%
tax rate for shareholders who are individuals), regardless of how long the

                                      -74-
<PAGE>


shareholder has held a Fund's or Portfolio'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 capital gains may be characterized as a
return of capital to shareholders (that is not taxable to a shareholder and
reduces the shareholder's basis in the shares) or, in some cases, as capital
gain.


     A Portfolio will not be able to offset gains realized by one Underlying
PIMCO Fund in which such Portfolio invests against losses realized by another
Underlying PIMCO Fund in which such Portfolio invests. A Portfolio's use of the
fund-of-funds structure could therefore affect the amount, timing and character
of distributions to shareholders. More generally, Funds that invest in other
investment companies will not be able to offset gains realized by one underlying
investment company against losses realized by another underlying investment
company. A Fund's investment in other investment companies could therefore
affect the amount, timing and character of distributions to shareholders of such
Fund.


     Depending on a Portfolio's percentage ownership in an Underlying PIMCO Fund
both before and after a redemption, a Portfolio's redemption of shares of such
Fund may cause the Portfolio to be treated as not receiving capital gain income
on the amount by which the distribution exceeds the Portfolio's tax basis in the
shares of the Underlying PIMCO Fund, but instead to be treated as receiving a
dividend taxable as ordinary income on the full amount of the distribution. This
could cause shareholders of a Portfolio to recognize higher amounts of ordinary
income than if the shareholders had held the shares of the Underlying PIMCO
Funds directly.

     Taxable shareholders should note that the timing of their investment or
redemptions could have undesirable tax consequences. Dividends and distributions
on shares of a Fund or Portfolio are generally subject to federal income tax as
described herein to the extent they do not exceed the Fund's or Portfolio's
realized income and gains, even though such dividends and distributions may
economically represent a return of a particular shareholder's investment. Such
distributions are likely to occur in respect of shares purchased at a time when
the net asset value of a Fund or Portfolio reflects gains that are either
unrealized, or realized but not distributed. Such realized gains may be required
to be distributed even when a Fund's or Portfolio's net asset value also
reflects unrealized losses.

Sales of Shares


     Upon the disposition of shares of a Fund or Portfolio (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. Long-term capital gains
will generally be taxed at a federal income tax rate of 20% to shareholders who
are individuals. For taxable years beginning after December 31, 2000, the
maximum capital gain tax rates for capital assets (including Fund shares) held
by a non-corporate shareholder for more than 5 years will be 8 percent and 18
percent (rather than 10 percent and 20 percent). The 18-percent rate applies
only to assets the holding period for which begins after December 31, 2000
(including by way of an election to mark the asset to the market, and to pay the
tax on any gain thereon, as of January 2, 2001). The mark-to-market election may
be disadvantageous from a federal tax perspective, and shareholders should
consult their tax advisors before making such an election. 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 or Portfolio may be required to withhold 31% of all taxable
distributions payable to shareholders who fail to provide the Fund or Portfolio
with their correct taxpayer identification number or to make required

                                      -75-
<PAGE>

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, Forward Contracts and Swap Agreements

     To the extent such investments are permissible for a Fund, the Fund's
transactions in options, futures contracts, hedging transactions, forward
contracts, straddles and foreign currencies will be subject to special tax rules
(including mark-to-market, constructive sale, straddle, wash sale and short sale
rules), the effect of which may be to accelerate income to the Fund, defer
losses to the Fund, cause adjustments in the holding periods of the Fund's
securities, convert long-term capital gains into short-term capital gains and
convert short-term capital losses into long-term capital losses. These rules
could therefore affect the amount, timing and character of distributions to
shareholders, including the Portfolios.

Passive Foreign Investment Companies

     Investment by a Fund in certain "passive foreign investment companies"
could subject the Fund to a U.S. federal income tax (including interest charges)
on distributions received from the company or on proceeds received from the
disposition of shares in the company, which tax cannot be eliminated by making
distributions to Fund shareholders. However, the Fund may elect to treat a
passive foreign investment company as a "qualified electing fund," in which case
the Fund will be required to include its share of the company's income and net
capital gains annually, regardless of whether it receives any distribution from
the company. The Fund also may make an election to mark the gains (and to a
limited extent losses) in such holdings "to the market" as though it had sold
and repurchased its holdings in those PFICs on the last day of the Fund's
taxable year. Such gains and losses are treated as ordinary income and loss. The
QEF and mark-to-market elections may accelerate the recognition of income
(without the receipt of cash) and increase the amount required to be distributed
for the Fund to avoid taxation. Making either of these elections therefore may
require a Fund to liquidate other investments (including when it is not
advantageous to do so) to meet its distribution requirement, which also may
accelerate the recognition of gain and affect a Fund's total return.

Foreign Currency Transactions

     A Fund's transactions in foreign currencies, foreign currency-denominated
debt securities and certain foreign currency options, futures contracts and
forward contracts (and similar instruments) may give rise to ordinary income or
loss to the extent such income or loss results from fluctuations in the value of
the foreign currency concerned.

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. If more than 50% of the value of a Fund's total assets at the close of
its 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
eligible 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 or her 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 as a foreign tax credit against his or
her U.S. federal income tax liability, subject to certain limitations. In
particular, shareholders must hold their shares (without protection from risk of
loss) on the ex-dividend date and for at least 15 more days during the 30-day
period surrounding the ex-dividend date to be eligible to claim a foreign tax
credit
                                      -76-
<PAGE>

with respect to a gain dividend. 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 electing Fund's 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,
receiv ables 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. Although a Portfolio
may itself be entitled to a deduction for such taxes paid by an Underlying PIMCO
Fund in which the Portfolio invests, the Portfolio will not be able to pass any
such credit or deduction through to its own shareholders. In addition, a Fund
which invests in other investment companies, including a Portfolio investing in
Underlying PIMCO Funds, may not be able to pass any such credit or deduction for
taxes paid by the underlying investment company through to its own shareholders.


Original Issue Discount and Pay-In-Kind Securities

     Current federal tax law requires the holder of a U.S. Treasury or other
fixed income zero coupon security to accrue as income each year a portion of the
discount at which the security was purchased, even though the holder receives no
interest payment in cash on the security during the year. In addition, pay-in-
kind securities will give rise to income which is required to be distributed and
is taxable even though the Fund holding the security receives no interest
payment in cash on the security during the year.

     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 (including certain pay-in-kind securities)
may be treated as a dividend for U.S. 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.

     Each Fund that holds the foregoing kinds of securities may be required to
pay out as an income distribution each year an amount which is greater than the
total amount of cash interest the Fund actually received.

                                      -77-
<PAGE>

Such distributions may be made from the cash assets of the Fund or by
liquidation of portfolio securities, if necessary. The Fund may realize gains or
losses from such liquidations. In the event the Fund realizes net capital gains
from such transactions, its shareholders may receive a larger capital gain
distribution, if any, than they would in the absence of such transactions.

Other Taxation


     From time to time, certain of the Trust's series may be considered under
the Code to be nonpublicly offered regulated investment companies. Pursuant to
Treasury Department regulations, certain expenses of nonpublicly offered
regulated investment companies, including advisory fees, may not be deductible
by certain shareholders, generally including individuals and entities that
compute their taxable income in the same manner as an individual (thus, for
example, a qualified pension plan is not subject to this rule). Such a
shareholder's pro rata portion of the affected expenses will be treated as an
additional dividend to the shareholder and will be deductible by such
shareholder, subject to the 2% "floor" on miscellaneous itemized deductions and
other limitations on itemized deductions set forth in the Code. A regulated
investment company generally will be classified as nonpublicly offered unless it
either has 500 shareholders at all times during a taxable year or continuously
offers shares pursuant to a public offering.

     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 and Portfolio will provide information
annually to shareholders indicating the amount and percentage of its 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. The Trust is organized as a Massachusetts business trust.
Under current law, so long as each Fund and Portfolio qualifies for the federal
income tax treatment described above, it is believed that neither the Trust nor
any Fund or Portfolio will be liable for any income or franchise tax imposed by
Massachusetts. Shareholders, in any event, are advised to consult their own tax
advisers with respect to the particular tax consequences to them of an
investment in a Fund or Portfolio.


                                OTHER INFORMATION

Capitalization

     The Trust is a Massachusetts business trust established under an Agreement
and Declaration of Trust as amended and restated on January 14, 1997. The
capitalization of the Trust consists solely of an unlimited number of shares of
beneficial interest. 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 or Portfolio, each
shareholder is entitled to receive his pro rata share of the net assets of that
Fund or Portfolio.

     Shares begin earning dividends on Fund shares the day after the Trust
receives the shareholder's purchase payment. Net investment income from interest
and dividends, if any, will be declared and paid monthly to shareholders of
record by the 30/70 Portfolio. Net investment income from interest and
dividends, if any, will be declared and paid quarterly to shareholders of record
by the NFJ Equity Income, NFJ Value, Equity Income,

                                      -78-
<PAGE>

Value and Renaissance Funds and the 60/40 Portfolio. Net investment income from
interest and dividends, if any, will be declared and paid at least annually to
shareholders of record by the other Funds and the 90/10 Portfolio. Any net
capital gains from the sale of portfolio securities will be distributed no less
frequently than once annually. Net short-term capital gains may be paid more
frequently. Dividend and capital gain distributions of a Fund or Portfolio will
be reinvested in additional shares of that Fund or Portfolio unless the
shareholder elects to have them paid in cash.

     Under Massachusetts law, shareholders could, under certain circumstances,
be held liable for the obligations of the Trust. However, the Second Amended and
Restated Agreement and Declaration of Trust (the "Declaration of Trust") of the
Trust disclaims shareholder liability for acts or obligations of the Trust and
requires that notice of such disclaimer be given in each agreement, obligation
or instrument entered into or executed by the Trust or the Trustees. The
Declaration of Trust also provides for indemnification out of a Fund's or
Portfolio's property for all loss and expense of any shareholder of that Fund or
Portfolio held liable on account of being or having been a shareholder. Thus,
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 Fund or Portfolio of which he or she is or was a shareholder 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 classes of shares of some or all of the Funds or
Portfolios. Information about a Fund's or Portfolio's performance is based on
that Fund's (or its predecessor's) or Portfolio's record to a recent date and is
not intended to indicate future performance.

     The total return of the classes of shares of the Funds and Portfolios may
be included in advertisements or other written material. When a Fund's or
Portfolio'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 or Portfolio 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) or Portfolio, as more fully described below. For
periods prior to the initial offering date of the advertised class of shares,
total return presentations for such class will be based on the historical
performance of an older class of the Fund (if any) restated, as necessary, 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
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 or Portfolio at the beginning of the relevant period to the
redemption value of the investment in the Fund or Portfolio 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 and Portfolios may also provide current distribution information
to their 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 or
Portfolio 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 or Portfolio has declared
and paid to shareholders as of the end of a specified period rather than the
Fund's or Portfolio's actual net investment income for that period.

                                      -79-
<PAGE>

     Performance information is computed separately for each class of a Fund or
Portfolio. Each Fund and Portfolio may from time to time include the total
return of each class of its shares in advertisements or in information furnished
to present or prospective shareholders. The Equity Income, Value and Renaissance
Funds and the 60/40 and 30/70 Portfolios may from time to time include the yield
and total return of each class of their shares in advertisements or information
furnished to present or prospective shareholders. Each Fund and Portfolio may
from time to time include in advertisements the total return of each class (and
yield of each class in the case of the Equity Income, Value and Renaissance
Funds and the 60/40 and 30/70 Portfolios) and the ranking of those 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 or Portfolio's net
asset values and public offering prices will separately present each class of
shares. The Funds and Portfolios 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.

     Investment results of the Funds and Portfolios will fluctuate over time,
and any representation of the Funds' or Portfolio's total return or yield for
any prior period should not be considered as a representation of what an
investor's total return or yield may be in any future period. The Trust's Annual
and Semi-Annual Reports contain additional performance information for the Funds
and Portfolios and are available upon request, without charge, by calling the
telephone numbers listed on the cover of this Statement of Additional
Information.

Calculation of Yield

     Quotations of yield for certain of the Funds and Portfolios 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)/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 September 30, 2000, the yields of the Equity
Income, Value and Renaissance Funds and the 60/40 and 30/70 Portfolios were as
follows (Class D shares were not offered during the period listed):

</TABLE>

     The yield of a Fund or Portfolio will vary from time to time depending upon
market conditions, the composition of its portfolio and operating expenses of
the Trust allocated to the Fund or Portfolio or its classes of shares. These
factors, possible differences in the methods used in calculating yield should be
considered when comparing a Fund's or Portfolio'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 or Portfolio's various
classes of shares. These yields do not take into account any applicable
contingent deferred sales charges.

     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 Portfolio, or a
class of shares thereof, will be expressed in terms of the average annual
compounded rate of return of a hypothetical investment in the Fund, Portfolio or
class over periods of one, five, and ten years (up to the life of the Fund or
Portfolio), calculated pursuant to the following formula: P (1 + T)/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 proportionate
share of Fund, Portfolio 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. Quotations of total return may also be shown for other
periods. The Funds and Portfolios may also, with respect to certain periods of
less than one year, provide total return information for that period that is
unannualized. Under applicable regulations, any such information is required to
be accompanied by standardized total return information.

     The performance results shown on the subsequent pages for the Equity
Income, Value, Renaissance, Growth, Select Growth, Target, Opportunity, Growth &
Income, Innovation and Select International Funds reflects the results of
operations under these Funds' previous Sub-Adviser(s). These Funds would not
necessarily have achieved the results shown under their current investment
management arrangements. The NFJ Value 25 Fund did not have any assets as of
June 30, 2000 and therefore no performance information is shown for this Fund.

     The table below sets forth the average annual total return of certain
classes of shares of the following Funds for periods ended June 30, 2000. 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.

     * Average annual total return presentations for a particular class of
     shares assume payment of the current maximum sales charge (if any)
     applicable to that class at the time of purchase and assume that the
     maximum CDSC (if any) for 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.

     ** 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 a particular 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 the
     Administrative Class) of the newer class. The adjusted performance also
     reflects the higher Fund operating expenses applicable to 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 and 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 .25%
     per annum), and may be paid by Class D (at a maximum rate of .25% per
     annum) and (ii) administrative fee charges associated with Class A, Class B
     and Class C shares (a maximum differential of .15% per annum) and Class D
     shares (a maximum differential of 0.40% per annum).

     *** The investment objective and policies of the Select Growth Fund were
     changed effective April 1, 2000. The investment objective and policies of
     the Growth & Income Fund were changed effective August 1, 2000. The
     investment objective and policies of the Select International Fund were
     changed effective November 1, 2000. Performance information for prior
     periods does not necessarily represent results that would have been
     obtained had the current investment objective and policies been in effect
     for all periods.

     The following table sets forth the average annual total return of certain
classes of shares of the following Funds (each of which, except for the Tax-
Efficient Equity Fund, was a series of PAF prior to its reorganization as a Fund
of the Trust on January 17, 1997) for periods ended June 30, 2000. Accordingly,
"Inception Date of Fund" for these Funds refers to the inception date of the PAF
predecessor series. Since Class C shares were offered since the inception of
each PAF series, total return presentations for periods prior to the Inception
Date of the other classes (with the exception of Class D, Institutional Class
and Administrative Class shares of the Innovation Fund, Institutional Class and
Administrative Class shares of the Target Fund and Administrative Class shares
of the Tax-Efficient Equity Fund) are based on the historical performance of
Class C shares, adjusted 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 and administrative fee charges. As described
below, performance presentations for periods prior to the Inception

     * Average annual total return presentations for a particular class of
     shares assume payment of the current maximum sales charge (if any)
     applicable to that class at the time of purchase and assume that the
     maximum CDSC (if any) for Class A, B and C shares was deducted at the
     times, in the amounts, and under the terms discussed in the Class A, B and
     C Prospectus.

     ** The investment objective and policies of the Renaissance Fund, Select
     Growth Fund and International Fund were changed effective February 1, 1992,
     March 31, 2000 and September 1, 1992, respectively. Performance information
     for prior periods does not necessarily represent results that would have
     been obtained had the current investment objective and policies been in
     effect for all periods.

     *** Class A, Class B, Class D, Institutional Class and Administrative Class
     total return presentations for the Funds listed for periods prior to the
     Inception Date of the particular class of a Fund (with the exception of
     Class D, Institutional Class and Administrative Class shares of the
     Innovation Fund, Class D, Institutional Class and Administrative Class
     shares of the Target Fund and Administrative Class shares of the
     Tax-Efficient Equity Fund) reflect the prior performance of Class C shares
     of the Fund, adjusted to reflect the actual sales charges (or no sales
     charges in the case of Class D, Institutional Class and Administrative
     Class shares) of the newer class. The adjusted performance also reflects
     any different operating expenses associated with the newer class. These
     include (i) 12b-1 distribution and servicing fees, which are paid by Class
     C and Class B (at a maximum rate of 1.00% per annum) and Class A and the
     Administrative Class (at a maximum rate of .25% per annum), may be paid by
     Class D (at a maximum rate of .25% per annum), and are not paid by the
     Institutional Class and (ii) administrative fee charges, which are lower
     than Class C charges for the Institutional and Administrative Classes (a
     maximum differential of .15% per annum) and higher for Class D (a maximum
     differential of .25% per annum). (Administrative fee charges are the same
     for Class A, B and C shares.) Performance presentations for periods prior
     to the Inception Date of Class D, Institutional Class and Administrative
     Class shares of the Innovation Fund, Class D, Institutional Class and
     Administrative Class shares of the Target Fund and Administrative Class
     Shares of the Tax-Efficient Equity Fund are based on the historical
     performance of Class A shares (which were also offered since inception of
     the Fund), adjusted in the manner described above.

     Note also that, prior to January 17, 1997, Class A, Class B and Class C
     shares of the former PAF series 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 a Fund attributable to Class
     A, Class B and Class C shares. Under the current fee structure, the Growth
     Fund, Target Fund, Opportunity Fund and International Fund are expected to
     have higher total Fund operating expenses than their predecessors had under
     the fee structure for PAF (prior to January 17, 1997). All other things
     being equal, such higher expenses have an adverse effect on total return
     performance for these Funds after January 17, 1997.

     (#) Where noted, the method of adjustment used in the table above for
     periods prior to the Inception Date of the noted classes of the noted Funds
     resulted in performance for the period shown which is higher than if the
     historical Class C or Class A share performance (i.e., the older class used
     for prior periods) 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 newer
     classes with lower operating expenses were calculated by essentially
     tacking to such classes' actual performance the actual performance (with
     adjustment for actual sales charges) of the older Class of 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 noted classes, on the
     historical performance of the older class adjusted to reflect the current

     The following table sets forth the average annual total return of each
class of shares of the Portfolios for periods ended June 30, 2000. Total return
presentations for periods prior to the Inception Date of Institutional Class and
Administrative Class shares are based on the historical performance of Class A
shares (which were offered since the inception of the Portfolios), adjusted to
reflect that there are no sales charges associated with Institutional Class and
Administrative Class shares and any different operating expenses associated with
these newer classes, such as lower 12b-1 distribution and servicing fees and/or

assume payment of the current maximum sales charge (if any) applicable to that
class at the time of purchase and assume that the maximum CDSC (if any) for
Class A, B and C shares was deducted at the times, in the amounts, and under the
terms discussed in the Retail Portfolio Prospectus.

** Institutional Class and Administrative Class total return presentations for
the Portfolios for periods prior to the Inception Date of these classes reflect
the prior performance of Class A shares, adjusted to reflect that there are no
sales charges associated with Institutional Class and Administrative Class
shares. The adjusted performance also reflects any different operating expenses
associated with the newer classes. These include (i) 12b-1 distribution and
servicing fees, which are the same for Class A and the Administrative Class but
are not paid by the Institutional Class and (ii) administrative fee charges,
which are lower than Class A charges for the Institutional and Administrative
Classes (a differential of .30% per annum).

     Performance information for a Fund or Portfolio may also be compared to:
(i) the Standard & Poor's 500 Composite Stock Price Index, the Dow Jones
Industrial Average, the Morgan Stanley Capital International EAFE (Europe,
Australia, Far East) Index, the Morgan Stanley Capital International Emerging
Markets Free Index, the International Finance Corporation Emerging Markets
Index, the Baring Emerging Markets Index, or other unmanaged indexes that
measure performance of a pertinent group of securities; (ii) other groups of
mutual funds tracked by Lipper Analytical Services ("Lipper"), a widely used
independent research firm which ranks mutual funds by overall performance,
investment objectives, and assets, or tracked by other services, companies,
publications, or persons who rank mutual funds on overall performance or other
criteria; and (iii) the Consumer Price Index (measure for inflation) to assess
the real rate of return from an investment in the Funds. Unmanaged indexes
(i.e., other than Lipper) generally do not reflect deductions for administrative
and management costs or expenses. The Adviser and any of the Sub-Advisers may
also report to shareholders or to the public in advertisements concerning the
performance of the Adviser and/or the Sub-Advisers as advisers to clients other
than the Trust, and on the comparative performance or standing of the Adviser
and/or the Sub-Advisers in relation to other money managers. Such comparative
information may be compiled or provided by independent ratings services or by
news organizations. Any performance information, whether related to the Funds or
Portfolios, the Adviser or the Sub-Advisers, should be considered in light of
the Funds' or Portfolios' investment objectives and policies, characteristics
and quality, and the market conditions during the time period indicated, and
should not be considered to be representative of what may be achieved in the
future.

     The total return of each class (and yield of each class in the case of the
Renaissance Fund and the 30/70 Portfolio) may be used to compare the performance
of each class of a Fund's or Portfolio's shares against certain widely
acknowledged standards or indexes for stock and bond market performance, against
interest rates on certificates of deposit and bank accounts, against the yield
on money market funds, against the cost of living (inflation) index, and against
hypothetical results based on a fixed rate of return.

     The S&P's Composite Index of 500 Stocks (the "S&P 500") is a market value-
weighted and unmanaged index showing the changes in the aggregate market value
of 500 stocks relative to the base period 1941-43. The S&P 500 is composed
almost entirely of common stocks of companies listed on the New York Stock
Exchange, although the common stocks of a few companies listed on the American
Stock Exchange or traded over-the-counter are included. The 500 companies
represented include 380 industrial, 10 transportation, 39 utilities and 71
financial services concerns. The S&P 500 represents about 73% of the market
value of all issues traded on the New York Stock Exchange.

     The S&P's 400 Mid-Cap Index (the "S&P 400 Mid-Cap Index") is a market
value-weighted and unmanaged index showing the changes in the aggregate market
value of 400 stocks of companies whose capitalization range from $100 million to
over $5 billion and which represent a wide range of industries. As of February
26, 1999, approximately 25% of the 400 stocks were stocks listed on the National
Association of

                                      -90-

Securities Dealers Automated Quotations ("NASDAQ") system, 73% were stocks
listed on the New York Stock Exchange and 2% were stocks listed on the American
Stock Exchange. The Standard & Poor's Midcap 400 Index P/TR consists of 400
domestic stocks chosen for market size (median market capitalization of $1.54
billion), liquidity and industry group representation. It is a market
value-weighted index (stock price times shares outstanding), with each stock
affecting the index in proportion to its market value. The index is comprised of
industrials, utilities, financials and transportation, in size order.

     The NASDAQ-OTC Price Index (the "NASDAQ Index") is a market value-weighted
and unmanaged index showing the changes in the aggregate market value of
approximately 3,500 stocks relative to the base measure of 100.00 on February 5,
1971. The NASDAQ Index is composed entirely of common stocks of companies traded
over-the-counter and often through the NASDAQ system. Only those over-
the-counter stocks having only one market maker or traded on exchanges are
excluded.

     The Russell 2000 Small Stock Index is an unmanaged index of the 2000
smallest securities in the Russell 3000 Index, representing approximately 7% of
the Russell 3000 Index. The Russell 3000 Index represents approximately 98% of
the U.S. equity market by capitalization. The Russell 1000 Index is composed of
the 1,000 largest companies in the Russell 3000 Index. The Russell 1000 Index
represents the universe of stocks from which most active money managers
typically select. This large cap index is highly correlated with the S&P 500.
The Russell 1000 Value Index contains stocks from the Russell 1000 Index with a
less-than-average growth orientation. It represents the universe of stocks from
which value managers typically select.

     The Lehman Government Bond Index (the "SL Government Index") is a measure
of the market value of all public obligations of the U.S. Treasury; all
publicly-issued debt of all agencies of the U.S. Government and all quasi-
federal corporations; and all corporate debt guaranteed by the U.S. Government.
Mortgage-backed securities, flower bonds and foreign targeted issues are not
included in the SL Government Index.

     The Lehman Government/Corporate Bond Index (the "SL Government/Corporate
Index") is a measure of the market value of approximately 5,000 bonds. To be
included in the SL Government/Corporate Index, an issue must have amounts
outstanding in excess of $1 million, have at least one year to maturity and be
rated "Baa" or higher by an NRSRO.

     BanXquote Money Market, a service of Masterfund Inc., provides the average
rate of return paid on 3-month certificates of deposit offered by major banks
and the average rate paid by major banks on bank money market funds. The
Donoghue Organization, Inc., a subsidiary of IBC USA Inc., publishes the Money
Fund Report which lists the 7-day average yield paid on money market funds.

     From time to time, the Trust may use, in its advertisements or information
furnished to present or prospective shareholders, data concerning the
performance and ranking of certain countries' stock markets, including
performance and ranking data based on annualized returns over one-, three-,
five- and ten-year periods. The Trust may also use data about the portion of
world equity capitalization represented by U.S. securities. As of December 31,
1998, the U.S. equity market capitalization represented approximately 40% of the
equity market capitalization of all the world's markets. This compares with 52%
in 1980 and 70% in 1972.

          From time to time, the Trust may use, in its advertisements and other
information relating to certain of the Funds and Portfolios, data concerning the
performance of stocks relative to that of fixed income investments and relative
to the cost of living over various periods of time. The table below sets forth
the annual returns for each calendar year from 1973 through 1999 (as well as a
cumulative return and average annual return for this period) for the S&P 500 and
Treasury bills (using the formula set forth after the table) as well as the
rates of inflation (based on the Consumer Price Index) during such periods.

     The average returns for Treasury bills were computed using the following
method. For each month during a period, the Treasury bill having the shortest
remaining maturity (but not less than one month) was selected. (Only the
remaining maturity was considered; the bill's original maturity was not
considered). The return for the selected Treasury bill was computed based on the
price of the bill as of the last trading day of the previous month and the price
on the last trading day of the current month. The price of the bill (P) at each
time (t) is given by:

          P\t\   =  [ 1- rd ]
                      -----
                    [  360  ]
                    where,
                          r = decimal yield on the bill at time t (the average
                              of bid and ask quotes); and
                          d = the number of days to maturity as of time t.

    Advertisements and information relating to the Target Fund may use data
comparing the performance of stocks of medium-sized companies to that of other
companies. The following table sets forth the annual returns for each year from
March 1981 (inception of Mid-Cap Index) through December 31, 1999 (as well as a
cumulative return and average annual return for this period) for stocks of
medium-sized companies (based on the Standard & Poor's Mid-Cap 400 Index),
stocks of small companies (based on the Russell 2000 Index) and stocks of larger
companies (based on the S&P 500).

     From time to time, the Trust may use, in its advertisements and other
information, data concerning the average price-to-earnings ("P/E") ratios of
"Value Stocks" and "Growth Stocks." For these purposes, the P/E ratios of Value
Stocks are measured by the P/E ratios of the stocks comprising the Russell 1000
Value Index, and the P/E ratios of Growth Stocks are measured by the P/E ratios
of the stocks comprising the Russell 1000 Growth Index. Both the Russell 1000
Value Index and Russell 1000 Growth Index are unmanaged indexes, and it is not
possible to invest directly in either index. The table below sets forth the
quarterly average P/E ratio of Value Stocks and the Average P/E ratio of Growth
Stocks for the periods from October 1, 1992 through June 30, 2000.

     From time to time, the Trust may use, in its advertisements and other
information, data comparing the average annual total return of "Small-Caps,"
which are stocks represented by the Ibbotson's U.S. Small Company Stock Total
Return Index, and "Large-Caps," which are stocks represented by the Standard &
Poors 500 Stock Composite Index. Both indexes are unmanaged indexes, and it is
not possible to invest directly in either index. For example, for the period
from December 31, 1926 through December 31, 1999, the average annual total
return of Small-Caps was 29.79%, and for Large-Caps was 21.04%.

     Advertisements and other information and other information relating to the
Funds may list the annual total returns of certain asset classes during
specified years. In such advertisements, the return of "Small Company Stocks"
will be measured by the Russell 2000 Index of small company stocks, the returns
of "Large Company Stocks" will be measured by the S&P 500, and the return of
"Intermediate-Term Government Bonds" will be measured by a one-bond portfolio
with a 5-year maturity as measured by Ibbotson Associates.

     Advertisements and other information relating to the Innovation Fund may
include information pertaining to the number of home internet subscriptions and
cellular phone users and sales of personal computers.

     The Trust may use, in its advertisements and other information, data
concerning the projected cost of a college education in future years based on
1997/1998 costs of college (using tuition and fees only) 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.

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 category* during the period from 1974 through 1999 was:

                Stocks:        15.2%
                Bonds:          9.2%
                T-Bills:        6.9%
                Inflation:      5.1%

     * Returns of unmanaged indexes do not reflect past or future performance of
     any of the Funds or Portfolios of PIMCO Funds: Multi-Manager Series. Stocks
     are represented by Ibbotson's Large Company Stock Total Return Index. Bonds
     are represented by Ibbotson's Long-term Corporate Bond Index. Treasury
     bills are represented by Ibbotson's Treasury Bill Index and Inflation is
     represented by the Cost of Living Index. These are all unmanaged indexes,
     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:

     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 period from
1980 through 1999, 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 Ibbottson's Treasury Bill Index (a "mixed
portfolio") would have ranged from -1.00% to 28.19% over the same period. The
average annual returns of each investment category* for each of the years from
1980 through 1999 is set forth in the following table.

     Articles or reports which include information relating to performance,
rankings and other characteristics of the Funds and Portfolios 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 and the Sub-Advisers,
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
or the Sub-Advisers 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 and
Portfolios.

     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 or Portfolios 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 Sub-Advisers who assist with portfolio management and research
activities on behalf of the Funds.

     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 may develop, from time
to time, model portfolios of the Funds and series of PIMS 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 PIMS. 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, the Sub-Advisers nor
Ibbotson represent or guarantee that investors who allocate their assets
according to Ibbotson's models will achieve their desired investment results.

Compliance Efforts Related to the Euro


     Problems may arise in conjunction with the recent and ongoing introduction
of the euro. Whether introducing the euro to financial companies' systems will
be problematic is not fully known; however, the cost associated with making
systems recognize the euro is not currently expected to be material.

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. Shareholders 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 10% 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.

      Shares entitle their holders to one vote per share (with proportionate
voting for fractional shares). All classes of shares of the Funds and Portfolios
have identical voting rights except that each class of shares has exclusive
voting rights on any matter submitted to shareholders that relates solely to
that class, and 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 has exclusive voting rights with respect
to matters pertaining to any distribution or servicing plan or agreement
applicable to that class. These shares are entitled to vote at meetings of
shareholders. Matters submitted to shareholder vote must be approved by each
Fund and Portfolio separately except (i) when required by the 1940 Act shares
shall be voted together and (ii) when the Trustees have determined that the
matter does not affect all Funds and Portfolios, then only shareholders of the
Fund(s) or Portfolio(s) affected shall be entitled to vote on the matter. All
classes of shares of a Fund or Portfolio will vote together, except with respect
to the Distribution and Servicing Plan applicable to Class A, Class B or Class C
shares, to the Distribution or Administrative Services Plans applicable to
Administrative Class shares, to the Administration Agreement as applicable to a
particular class or classes, or when a class vote is required as specified above
or otherwise by the 1940 Act.

     The Trust's shares do not have cumulative voting rights. Therefore, the
holders 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.


     The Portfolios will vote shares of each Underlying PIMCO Fund which they
own in their discretion in accordance with the Portfolios' proxy voting
policies.

Certain Ownership of Trust Shares


     As of October 4, 2000, the Trust believes that the Trustees and officers of
the Trust, as a group, owned less than one percent of each class of each Fund
and Portfolio and of the Trust as a whole. Appendix B list persons who own of
record or beneficially 5% or more of the noted class of shares of the Funds as
of October 4, 2000, as well as information about owners of 25% or more of the
outstanding shares of beneficial interest of the Funds, and therefore may be
presumed to "control" the Fund, as that term is defined in the 1940 Act.

Custodian

     State Street Bank & Trust Co. ("State Street"), 801 Pennsylvania, Kansas
City, Missouri 64105, serves as custodian for assets of all Funds and
Portfolios, including as custodian of the Trust for the custody of the

                                      -99-
<PAGE>

foreign securities acquired by those Funds that invest in foreign securities.
Under the agreement, State Street may hold foreign securities at its principal
offices and its 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 or other exemptions 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 currently 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; and further risks of
potential nationalization or expropriation of Trust assets, although the
Trustees reserve the right to delegate their selection responsibilities in light
of recent amendments to Rule 17f-5 under the 1940 Act, in which case the factors
for consideration would differ from those referenced above. Currently, the Board
of Trustees reviews annually the continuance of foreign custodial arrangements
for the Trust, but reserves the right to discontinue this practice as permitted
by the recent amendments to Rule 17f-5. 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.

Codes of Ethics


     The Trust, PIMCO Advisors, PAIA, Cadence, NFJ, Parametric, Blairlogie and
the Distributor have adopted Codes of Ethics pursuant to the requirements of the
1940 Act. These Codes of Ethics permit personnel subject to the Codes to invest
in securities, including securities that may be purchased or held by the Funds
or Portfolios.

Independent Accountants

     PricewaterhouseCoopers LLP, 1055 Broadway, Kansas City, Missouri 64105,
serves as the independent public accountants for the Funds and Portfolios.
PricewaterhouseCoopers LLP provides audit services, accounting assistance, and
consultation in connection with SEC filings.

Transfer and Shareholder Servicing Agents

     PFPC, Inc., P.O. Box 9688, Providence, Rhode Island 02940, serves as the
Transfer and Shareholder Servicing Agent for the Trust's Class A, Class B, Class
C and Class D shares. National Financial Data Services, 330 West 9th Street, 4th
Floor, Kansas City, Missouri 64105, serves as the Transfer Agent for the Trust's
Institutional and Administrative Class shares.

Legal Counsel

     Ropes & Gray, One International Place, Boston, Massachusetts 02110 serves
as legal counsel to the Trust.

                                   APPENDIX A

                        DESCRIPTION OF SECURITIES RATINGS

     Certain of the Funds make use of average portfolio credit quality standards
to assist institutional investors whose own investment guidelines limit their
investments accordingly.  In determining a Fund's overall dollar-weighted
average quality, unrated securities are treated as if rated, based on the
Adviser's or Sub-Adviser's view of their comparability to rated securities.  A
Fund's use of average quality criteria is intended to be a guide for those
investors whose investment guidelines require that assets be invested according
to comparable criteria. Reference to an overall average quality rating for a
Fund does not mean that all securities held by the Fund will be rated in that
category or higher. 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 the Adviser or a Sub-Adviser to be of comparable
quality).  The percentage of a Fund's assets invested in securities in a
particular rating category will vary.  Following is a description of Moody's and
S&P's ratings applicable to fixed income securities.

MOODY'S INVESTORS SERVICE, INC.

     CORPORATE AND MUNICIPAL BOND RATINGS

     Aaa:  Bonds which are rated Aaa are judged to be of the best 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
                                      A-1
<PAGE>

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 bond ratings, where specified, are applicable to financial
contracts, senior bank obligations and insurance company senior policyholder and
claims obligations with an original maturity in excess of one year. Obligations
relying upon support mechanisms such as letter-of-credit and bonds of indemnity
are excluded unless explicitly rated.  Obligations of a branch of a bank are
considered to be domiciled in the country in which the branch is located.

     Unless noted as an exception, Moody's rating on a bank's ability to repay
senior obligations extends only to branches located in countries which carry a
Moody's Sovereign Rating for Bank Deposits.  Such branch obligations are rated
at the lower of the bank's rating or Moody's Sovereign Rating for the Bank
Deposits for the country in which the branch is located.  When the currency in
which an obligation is denominated is not the same as the currency of the
country in which the obligation is domiciled, Moody's ratings do not incorporate
an opinion as to whether payment of the obligation will be affected by the
actions of the government controlling the currency of denomination.  In
addition, risk associated with bilateral conflicts between an investor's home
country and either the issuer's home country or the country where an issuer
branch is located are not incorporated into Moody's ratings.

     Moody's makes no representation that rated bank obligations or insurance
company obligations are exempt from registration under the U.S. Securities Act
of 1933 or issued in conformity with any other applicable law or regulation.
Nor does Moody's represent any specific bank or insurance company obligation  is
legally enforceable or a valid senior obligation of a rated issuer.

     Moody's applies numerical modifiers, 1, 2, and 3 in each generic rating
classified from Aa through Caa 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.

     CORPORATE SHORT-TERM DEBT RATINGS

     Moody's short-term debt ratings are opinions of the ability of issuers to
repay punctually senior debt obligations.  These obligations have an original
maturity not exceeding one year, unless explicitly noted.

     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

                                      A-2
<PAGE>

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.

STANDARD & POOR'S RATINGS SERVICES

     ISSUE CREDIT RATING DEFINITIONS

     A Standard & Poor's issue credit rating is a current opinion of the
creditworthiness of an obligor with respect to a specific financial obligation,
a specific class of financial obligations, or a specific financial program
(including ratings on medium term note programs and commercial paper programs).
It takes into consideration the creditworthiness of guarantors, insurers, or
other forms of credit enhancement on the obligation and takes into account the
currency in which the obligation is denominated.  The issue credit rating is not
a recommendation to purchase, sell, or hold a financial obligation, inasmuch as
it does not comment as to market price or suitability for a particular investor.

     Issue credit ratings are based on current information furnished by the
obligors or obtained by Standard & Poor's from other sources it considers
reliable.  Standard & Poor's does not perform an audit in connection with any
credit rating and may, on occasion, rely on unaudited financial information.
Credit ratings may be changed, suspended, or withdrawn as a result of changes
in, or unavailability of, such information, or based on other circumstances.

     Issue credit ratings can be either long-term or short-term.  Short-term
ratings are generally assigned to those obligations considered short term in the
relevant market.  In the U.S., for example, that means obligations with an
original maturity of no more than 365 days -- including commercial paper.
Short-term ratings are also used to indicate the creditworthiness of an obligor
with respect to put features on long-term obligations.  The result is a dual
rating, in which the short-term rating addresses the put feature, in addition to
the usual long-term rating.  Medium-term notes are assigned long-term ratings.

     Issue credit ratings are based, in varying degrees, on the following
considerations:  likelihood of payment -- capacity and willingness of the
obligor to meet its financial commitment on an obligation in accordance with the
terms of the obligation;  nature of and provisions of the obligation; protection
afforded by , and relative position of, the obligation in the event of
bankruptcy, reorganization, or other arrangement under the laws of bankruptcy
and other laws affecting creditors' rights.

     The issue rating definitions are expressed in terms of default risk.  As
such, they pertain to senior obligations of an entity.  Junior obligations are
typically rated lower than senior obligations, to reflect the lower priority in
bankruptcy, as noted above.  (Such differentiation applies when an entity has
both senior and subordinated obligations, secured and unsecured obligations, or
operating company and holding company obligations.)  Accordingly, in the case of
junior debt, the rating may not conform exactly with the category definition.

     CORPORATE AND MUNICIPAL BOND RATINGS

     Investment Grade

     AAA:  An obligation rated AAA has the highest rating assigned by Standard &
Poor's.  The obligor's capacity to meet its financial commitment on the
obligation is extremely strong.

     AA:  An obligation rated 'AA' differs from the highest rated obligations
only in small degree.  The obligor's capacity to meet its financial commitment
on the obligation is very strong.

     A:  An obligation rated 'A' is somewhat more susceptible to the adverse
effects of changes in

                                      A-3
<PAGE>

circumstances and economic conditions than obligations in higher rated
categories. However, the obligor's capacity to meet its financial commitment on
the obligation is still strong.

     BBB:  An obligation rated 'BBB' exhibits adequate protection parameters.
However, adverse economic conditions or changing circumstances are more likely
to lead to a weakened capacity o the obligor to meet its financial commitment on
the obligation.

     Speculative Grade

     Obligations  rated 'BB', 'B', 'CCC', 'CC', and 'C' are 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:  An obligation rated 'BB' is less vulnerable to nonpayment than other
speculative issues.  However, it faces major ongoing uncertainties or exposure
to adverse business, financial, or economic conditions which could lead to the
obligors's inadequate capacity to meet its financial commitment on the
obligation.

     B:  An obligation rated 'B' is more vulnerable to nonpayment than
obligations rated 'BB', but the obligor currently has the capacity to meet its
financial commitment on the obligation.  Adverse business, financial, or
economic conditions will likely impair the obligor's capacity or willingness to
meet its financial commitment on the obligation.

     CCC:  An obligation rated 'CCC' is currently vulnerable to nonpayment, and
is dependent upon favorable business, financial, and economic conditions for the
obligor to meet its financial commitment on the obligation.  In the event of
adverse business, financial, or economic conditions, the obligor is not likely
to have the capacity to meet its financial commitment on the obligation.

     CC:  An obligation rated 'CC' is currently highly vulnerable to nonpayment.

     C:  A subordinated debt or preferred stock obligation rated 'C' is
CURRENTLY HIGHLY VULNERABLE to nonpayment.  The 'C' rating may be used to cover
a situation where a bankruptcy petition has been filed or similar action taken,
but payments on this obligation are being continued.  A 'C' also will be
assigned to a preferred stock issue in arrears on dividends or sinking fund
payments, but that is currently paying.

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

     D:  An obligation rated 'D' is in payment default.  The 'D' rating category
is used when payments on an obligation are not made on the date due even if the
applicable grace period has not expired, unless Standard & Poors's believes that
such payments will be made during such grace period.  The 'D' rating also will
be used upon the filing of a bankruptcy petition or the taking of a similar
action if payments on an obligation 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:  This symbol is attached to the ratings of instruments with significant
noncredit risks.  It highlights risks to principal or volatility of expected
returns which are not addressed in the credit rating.  Examples include:


                                      A-4
<PAGE>

obligations linked or indexed to equities, currencies, or commodities;
obligations exposed to severe prepayment risk -- such as interest-only or
principal-only mortgage securities; and obligations with unusually risky
interest terms, such as inverse floaters.

     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.:  This indicates that no rating has been requested, that there is
insufficient information on which to base a rating, or that Standard & Poor's's
does not rate a particular obligation as a matter of policy.

     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.

     COMMERCIAL PAPER RATING DEFINITIONS

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

     A-1:  A short-term obligation rated 'A-1' is rated in the highest category
by Standard & Poor's.  The obligor's capacity to meet its financial commitment
on the obligation is strong.  Within this category, certain obligations are
designated with a plus sign (+).  This indicates that the obligors's capacity to
meet its financial commitment on these obligations is extremely strong.

     A-2:  A short-term obligation rated 'A-2' is somewhat more susceptible to
the adverse effects of changes in circumstances and economic conditions than
obligations in higher rating categories.  However, the obligor's capacity to
meet its financial commitment on the obligation is satisfactory.

     A-3:  A short-term obligation rated 'A-3' exhibits adequate protection
parameters.  However, adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity of the obligor to meet its financial
commitment on the obligation.

     B:  A short-term obligation rated 'B' is regarded as having significant
speculative characteristics.  The obligor currently has the capacity to meet its
financial commitment on the obligation; however, it faces major ongoing
uncertainties which could lead to the obligor's inadequate capacity to meet its
financial commitment on the obligation.

     C: A short-term obligation rated 'C' is currently vulnerable to nonpayment
and is dependent upon favorable business, financial, and economic conditions for
the obligor to meet its financial commitment on the obligation.

     D:  A short-term obligation rated 'D' is in payment default.  The 'D'
rating category is used when payments on an obligation are not made on the date
due even if the applicable grace period has not expired, unless Standard &
Poor's believes that such payments will be made during such grace period.  The
'D' rating also will be used upon the filing of a bankruptcy petition or the
taking of a similar action if payments on an obligation are jeopardized.

     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 Standard & Poor's by the issuer or obtained from other sources it considers
reliable. Standard & Poor's does not perform an audit in connection with any
rating and may, on occasion, rely on unaudited financial information.  The

PIMCO Funds Shareholders' Guide
  for Class A, B and C Shares


November 1, 2000

This Guide relates to the mutual funds (each, a "Fund") that are series of PIMCO
Funds: Multi-Manager Series (the "MMS Trust") and PIMCO Funds: Pacific
Investment Management Series (the "PIMS Trust" and, together with the MMS Trust,
the "Trusts"). Unless otherwise indicated, references to the Funds include the
PIMCO Funds Asset Allocation Series portfolios (the "Portfolios"). The
Portfolios are so called "funds of funds" which are series of the MMS Trust.
Class A, B and C shares of the MMS Trust, the PIMS Trust and the Portfolios are
offered through four separate prospectuses (each, a "Retail Prospectus"). The
information in this Guide is subject to change without notice at the option of
the Trusts, the Advisers or the Distributor.

This Guide contains detailed information about Fund purchase, redemption and
exchange options and procedures and other information about the Funds. This
Guide is not a prospectus, and should be used in conjunction with the applicable
Retail Prospectus. This Guide, and the information disclosed herein, is
incorporated by reference in, and considered part of, the Statement of
Additional Information corresponding to each Retail Prospectus.

PIMCO Funds Distributors LLC distributes the Funds' shares. You can call PIMCO
Funds Distributors LLC at 1-800-426-0107 to find out more about the Funds and
other funds in the PIMCO Funds family. You can also visit our Web site at

How to Buy Shares

         Class A, Class B and Class C shares of each Fund are continuously
offered through the Trusts' principal underwriter, PIMCO Funds Distributors LLC
(the "Distributor") and through other firms which have dealer agreements with
the Distributor ("participating brokers") or which have agreed to act as
introducing brokers for the Distributor ("introducing brokers"). The Distributor
is a wholly owned subsidiary of PIMCO Advisors L.P. ("PIMCO Advisors"), the
investment adviser to the Funds that are series of the MMS Trust, and an
affiliate of Pacific Investment Management Company LLC ("Pacific Investment
Management Company"), the investment adviser to the Funds that are series of the
PIMS Trust. PIMCO Advisors and Pacific Investment Management Company are each
referred to herein as an "Adviser."

         There are two ways to purchase Class A, Class B or Class C shares:
either (i) through your dealer or broker which has a dealer agreement with the
Distributor or (ii) directly by mailing a PIMCO Funds account application (an
"account application") with payment, as described below under the heading Direct
Investment, to the Distributor (if no dealer is named in the account
application, the Distributor may act as dealer). Class A, Class B and Class C
shares of the Short Duration Municipal Income Fund and Class B and Class C
shares of the California Municipal Bond, California Intermediate Municipal Bond
and New York Municipal Bond Funds are not offered as of the date of this Guide;
however, investment opportunities in these Funds may be available in the future.

         Shares may be purchased at a price equal to their net asset value per
share next determined after receipt of an order, plus a sales charge which, at
the election of the purchaser, may be imposed either (i) at the time of the
purchase in the case of Class A shares (the "initial sales charge alternative"),
(ii) on a contingent deferred basis in the case of Class B shares (the "deferred
sales charge alternative") or (iii) by the deduction of an ongoing asset based
sales charge in the case of Class C shares (the "asset based sales charge
alternative" circumstances, Class A and Class C shares are also subject to a
Contingent Deferred Sales Charge ("CDSC"). See "Alternative Purchase
Arrangements." Purchase payments for Class B and Class C shares are fully
invested at the net asset value next determined after acceptance of the trade.
Purchase payments for Class A shares, less the applicable sales charge, are
invested at the net asset value next determined after acceptance of the trade.

         All purchase orders received by the Distributor prior to the close of
regular trading (normally 4:00 p.m., Eastern time) on the New York Stock
Exchange on a regular business day are processed at that day's offering price.
However, orders received by the Distributor from dealers or brokers after the
offering price is determined that day will receive such offering price if the
orders were received by the dealer or broker 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 5:00 p.m., Eastern time) or, in the
case of certain retirement plans,

                                     SG-3
<PAGE>

received by the Distributor prior to 9:30 a.m., Eastern time on the next
business day. Purchase orders received on other than a regular business day will
be executed on the next succeeding regular business day. 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 New York Stock
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.

         Except for purchases through the PIMCO Funds Auto-Invest plan, the
PIMCO Funds Auto-Exchange plan, investments pursuant to the Uniform Gifts to
Minors Act, and tax-qualified and wrap programs referred to below under "Tax-
Qualified Retirement Plans" and Alternative Purchase Arrangements--Sales at Net
Asset Value," and sales to certain registered representatives as described below
under "Registered Representatives' Investments," the minimum initial investment
in Class A, Class B or Class C shares of any Fund is $2,500, and the minimum
additional investment is $100 per Fund. For information about dealer
commissions, see "Alternative Purchase Arrangements" below. Persons selling Fund
shares may receive different compensation for selling Class A, Class B or Class
C shares. Normally, Fund shares purchased through participating brokers are held
in the investor's account with that broker. No share certificates will be issued
unless specifically requested in writing by an investor or broker-dealer.

Direct Investment

         Investors who wish to invest in Class A, Class B or Class C shares of a
Fund directly, rather than through a participating broker, may do so by opening
an account with the Distributor. To open an account, an investor should complete
the account application. All shareholders who open direct accounts with the
Distributor will receive from the Distributor individual confirmations of each
purchase, redemption, dividend reinvestment, exchange or transfer of Fund
shares, including the total number of Fund shares owned as of the confirmation
date, except that purchases which result from the reinvestment of daily-accrued
dividends and/or distributions will be confirmed once each calendar quarter. See
"Distributions" in the applicable Retail Prospectus. Information regarding
direct investment or any other features or plans offered by the Trusts may be
obtained by calling the Distributor at 1-800-426-0107 or by calling your broker.

Purchase by Mail

         Investors who wish to invest directly may send a check payable to PIMCO
Funds Distributors LLC, along with a completed application form to:

                                     SG-4
<PAGE>

         PIMCO Funds Distributors LLC
         P.O. Box 9688
         Providence, RI  02940-0926

         Purchases are accepted subject to collection of checks at full value
and conversion into federal funds. Payment by a check drawn on any member of the
Federal Reserve System can normally be converted into federal funds within two
business days after receipt of the check. Checks drawn on a non-member bank may
take up to 15 days to convert into federal funds. In all cases, the purchase
price is based on the net asset value next determined after the purchase order
and check are accepted, even though the check may not yet have been converted
into federal funds.

Subsequent Purchases of Shares

         Subsequent purchases of Class A, Class B or Class C shares can be made
as indicated above by mailing a check with a letter describing the investment or
with the additional investment portion of a confirmation statement. Except for
subsequent purchases through the PIMCO Funds Auto-Invest plan, the PIMCO Funds
Auto-Exchange plan, tax-qualified programs and PIMCO Funds Fund Link referred to
below, and except during periods when an Automatic Withdrawal Plan is in effect,
the minimum subsequent purchase is $100 in any Fund. All payments should be made
payable to PIMCO Funds Distributors LLC and should clearly indicate the
shareholder's account number. Checks should be mailed to the address above under
"Purchase by Mail."

Tax-Qualified Retirement Plans

         The Distributor makes available retirement plan services and documents
for Individual Retirement Accounts (IRAs), including Roth IRAs, for which Boston
Safe Deposit & Trust Company serves as trustee and for IRA Accounts established
with Form 5305-SIMPLE under the Internal Revenue Code of 1986, as amended (the
"Code"). These accounts include Simplified Employee Pension Plan (SEP) and
Salary Reduction Simplified Employee Pension Plan (SAR/SEP) IRA and SIMPLE IRA
accounts and prototype documents. In addition, prototype documents are available
for establishing 403(b)(7) custodial accounts with Boston Safe Deposit & Trust
Company as custodian. This type of plan is available to employees of certain
non-profit organizations.

                                     SG-5
<PAGE>

The minimum initial investmentfor all tax-qualified plans (except for employer-
sponsored plans, SIMPLE IRAs, SEPs and SAR/SEPs) is $1,000 per Fund and the
minimum subsequent investment is $100. The minimum initial investment for
employer-sponsored plans, SIMPLE IRAs, SEPs and SAR/SEPs and the minimum
subsequent investment per Fund for all such plans is $50.

PIMCO Funds Auto-Invest

         The PIMCO Funds Auto-Invest plan provides for periodic investments into
the shareholder's account with the Trust by means of automatic transfers of a
designated amount from the shareholder's bank account. The minimum investment
for eligibility in the PIMCO Funds Auto-Invest plan is $1,000 per Fund.
Investments may be made monthly or quarterly, and may be in any amount subject
to a minimum of $50 per month for each Fund in which shares are purchased
through the plan. Further information regarding the PIMCO Funds Auto-Invest plan
is available from the Distributor or participating brokers. You may enroll by
completing the appropriate section on the account application, or you may obtain
an Auto-Invest application by calling the Distributor or your broker.

Registered Representatives' Investments

        Current registered representatives and other full-time employees of
participating brokers or such persons' spouses or trusts or custodial accounts
for their minor children may purchase Class A shares at net asset value without
a sales charge. The minimum initial investment in each case in $500 per Fund and
the minimum subsequent investment is $50.

PIMCO Funds Auto-Exchange

         The PIMCO Funds Auto-Exchange plan establishes regular, periodic
exchanges from one Fund account to another Fund account. The plan provides for
regular investments into a shareholder's account in a specific Fund by means of
automatic exchanges of a designated amount from another Fund account of the same
class of shares and with identical account registration.

         Exchanges may be made monthly or quarterly, and may be in any amount
subject to a minimum of $1,000 to open a new Fund account and of $50 for any
existing Fund account for which shares are purchased through the plan.

         Further information regarding the PIMCO Funds Auto-Exchange plan is
available from the Distributor at 1-800-426-0107 or participating brokers. You
may enroll by completing an application which may be obtained from the
Distributor or by telephone request at 1-800-426-0107. For more information on
exchanges, see "Exchange Privilege."

PIMCO Funds Fund Link

         PIMCO Funds Fund Link ("Fund Link") connects your Fund account(s) with
a bank account. Fund Link may be used for subsequent purchases and for
redemptions and other transactions described under "How to Redeem." Purchase
transactions are effected by

                                     SG-6
<PAGE>

electronic funds transfers from the shareholder's account at a U.S. bank or
other financial institution that is an Automated Clearing House ("ACH") member.
Investors may use Fund Link to make subsequent purchases of shares in any amount
greater than $50 to $10,000. To initiate such purchases, call 1-800-426-0107.
All such calls will be recorded. Fund Link is normally established within
45 days of receipt of a Fund Link application by PFPC, Inc. (the "Transfer
Agent"), the Funds' transfer agent for Class A, B and C shares. The minimum
investment by Fund Link is $50 per Fund. Shares will be purchased on the regular
business day the Distributor receives the funds through the ACH system, provided
the funds are received before the close of regular trading on the New York Stock
Exchange. If the funds are received after the close of regular trading, the
shares will be purchased on the next regular business day.

         Fund Link privileges must be requested on the account application. To
establish Fund Link on an existing account, complete a Fund Link application,
which is available from the Distributor or your broker, with signatures
guaranteed from all shareholders of record for the account. See "Signature
Guarantee" below. Such privileges apply to each shareholder of record for the
account unless and until the Distributor receives written instructions from a
shareholder of record canceling such privileges. Changes of bank account
information must be made by completing a new Fund Link application signed by all
owners of record of the account, with all signatures guaranteed. The
Distributor, the Transfer Agent and the Fund may rely on any telephone
instructions believed to be genuine and will not be responsible to shareholders
for any damage, loss or expenses arising out of such instructions. The Fund
reserves the right to amend, suspend or discontinue Fund Link privileges at any
time without prior notice. Fund Link does not apply to shares held in broker
"street name" accounts.

Signature Guarantee

         When a signature guarantee is called for, the shareholder should have
"Signature Guaranteed" stamped under his signature and guaranteed by any of the
following entities: U.S. banks, foreign banks having a U.S. correspondent bank,
credit unions, savings associations, U.S. registered dealers and brokers,
municipal securities dealers and brokers, government securities dealers and
brokers, national securities exchanges, registered securities associations and
clearing agencies (each an "Eligible Guarantor Institution"). The Distributor
reserves the right to reject any signature guarantee pursuant to its written
signature guarantee standards or procedures, which permit it to reject signature
guarantees from Eligible Guarantor Institutions that do not, based on credit
guidelines or other requirements, satisfy such written standards or procedures.

         Beginning January 1, 2001, when a signature guarantee is called for, a
"medallion" signature guarantee will be required. A medallion signature
guarantee may be obtained from a domestic bank or trust company, broker, dealer,
clearing agency, savings association or other financial institution which is
participating in a medallion program recognized by the Securities Transfer
Association. The three recognized medallion programs are the Securities Transfer

                                     SG-7
<PAGE>

Agents Medallion Program (STAMP), Stock Exchanges Medallion Program (SEMP) and
New York Stock Exchange, Inc. Medallion Signature Program (NYSE MSP). Signature
guarantees from financial institutions which are not participating in one of
these programs will not be accepted. Please note that financial institutions
participating in a recognized medallion program may still be ineligible to
provide a signature guarantee for transactions of greater than a specified
dollar amount.

         The Distributor reserves the right to modify its signature guarantee
standards at any time. The Funds may change the signature guarantee requirements
from time to time upon notice to shareholders, which may, but is not required
to, be given by means of a new or supplemented Retail Prospectus or a new or
supplemented Guide. Shareholders should contact the Distributor for additional
details regarding the Funds' signature guarantee requirements.

Account Registration Changes

         Changes in registration or account privileges may be made in writing to
the Transfer Agent. Signature guarantees may be required. See "Signature
Guarantee" above. All correspondence must include the account number and must be
sent to:

         PIMCO Funds Distributors LLC
         P.O. Box 9688
         Providence, RI  02940-0926

Small Account Fee

         Because of the disproportionately high costs of servicing accounts with
low balances, a fee at an annual rate of $16 (paid to the applicable Fund's
administrator) will automatically be deducted from direct Fund accounts with
balances falling below a minimum level. The valuation of Fund accounts and the
deduction are expected to take place during the last five business days of each
calendar quarter. The fee will be deducted in quarterly installments from Fund
accounts with balances below $2,500, except for Uniform Gift to Minors, IRA,
Roth IRA and Auto-Invest accounts, for which the limit is $1,000. The fee also
applies to employer-sponsored retirement plan accounts, Money Purchase and/or
Profit Sharing plans, 401(k) plans, 403(b)(7) custodial accounts, SIMPLE IRAs,
SEPs and SAR/SEPs. (A separate custodial fee may apply to IRAs, Roth IRAs and
other retirement accounts.) No fee will be charged on any Fund account of a
shareholder if the aggregate value of all of the shareholder's Fund accounts is
at least $50,000. Any applicable small account fee will be deducted
automatically from your below-minimum Fund account in quarterly installments and
paid to the Administrator. Each Fund account will normally be valued, and any
deduction taken, during the last five business days of each calendar quarter. No
small account fee will be charged to employee and employee-related accounts of
PIMCO Advisors and/or, in the discretion of PIMCO Advisors, its affiliates.

                                     SG-8
<PAGE>

Minimum Account Size

         Due to the relatively high cost to the Funds of maintaining small
accounts, you are asked to maintain an account balance in each Fund in which you
invest of at least the amount necessary to open the type of account involved. If
your balance for any Fund is below such minimum for three months or longer, the
applicable Fund's administrator shall have the right (except in the case of
employer-sponsored retirement accounts) to close that Fund account after giving
you 60 days in which to increase your balance. Your Fund account will not be
liquidated if the reduction in size is due solely to market decline in the value
of your Fund shares or if the aggregate value of all your accounts in PIMCO
Funds exceeds $50,000.


Alternative Purchase Arrangements

         The Funds offer investors Class A, Class B and Class C shares in the
applicable Retail Prospectus. Class A, B and C shares bear sales charges in
different forms and amounts and bear different levels of expenses, as described
below. Through separate prospectuses, certain of the Funds currently offer up to
three additional classes of shares in the United States: Class D, Institutional
Class and Administrative Class shares. Class D shares are offered through
financial intermediaries. Institutional Class shares are offered to pension and
profit sharing plans, employee benefit trusts, endowments, foundations,
corporations and other high net worth individuals. Administrative Class shares
are offered primarily through employee benefit plan alliances, broker-dealers
and other intermediaries. Class D, Institutional Class and Administrative Class
shares are sold without a sales charge and have different expenses than Class A,
Class B and Class C shares. As a result of lower sales charges and/or operating
expenses, Class D, Institutional Class and Administrative Class shares are
generally expected to achieve higher investment returns than Class A, Class B or
Class C shares. Certain Funds also offer up to two additional classes of shares
that are offered only to non-U.S. investors outside the United States: Class J
and Class K shares. To obtain more information about the other classes of
shares, please call the applicable Trust at 1-800-927-4648 (for Institutional
and Administrative Class shares) or the Distributor at 1-888-87-PIMCO (for Class
D shares).

         The alternative purchase arrangements described in this Guide are
designed to enable a retail investor to choose the method of purchasing Fund
shares that is most beneficial to the investor based on all factors to be
considered, including the amount and intended length of the investment, the
particular Fund and whether the investor intends to exchange shares for shares
of other Funds. Generally, when making an investment decision, investors should
consider the

                                     SG-9
<PAGE>

anticipated life of an intended investment in the Funds, the accumulated
distribution and servicing fees plus CDSCs on Class B or Class C shares, the
initial sales charge plus accumulated servicing fees on Class A shares (plus a
CDSC in certain circumstances), the possibility that the anticipated higher
return on Class A shares due to the lower ongoing charges will offset the
initial sales charge paid on such shares, the automatic conversion of Class B
shares to Class A shares and the difference in the CDSCs applicable to Class A,
Class B and Class C shares.

Class A The initial sales charge alternative (Class A) might be preferred by
investors purchasing shares of sufficient aggregate value to qualify for
reductions in the initial sales charge applicable to such shares. Similar
reductions are not available on the contingent deferred sales charge alternative
(Class B) or the asset based sales charge alternative (Class C). Class A shares
are subject to a servicing fee but are not subject to a distribution fee and,
accordingly, such shares are expected to pay correspondingly higher dividends on
a per share basis. However, because initial sales charges are deducted at the
time of purchase, not all of the purchase payment for Class A shares is invested
initially. Class B and Class C shares might be preferable to investors who wish
to have all purchase payments invested initially, although remaining subject to
higher distribution and servicing fees and, for certain periods, being subject
to a CDSC. An investor who qualifies for an elimination of the Class A initial
sales charge should also consider whether he or she anticipates redeeming shares
in a time period which will subject such shares to a CDSC as described below.
See "Initial Sales Charge Alternative--Class A Shares--Class A Deferred Sales
Charge" below.

Class B Class B shares might be preferred by investors who intend to invest in
the Funds for longer periods and who do not intend to purchase shares of
sufficient aggregate value to qualify for sales charge reductions applicable to
Class A shares. Both Class B and Class C shares can be purchased at net asset
value without an initial sales charge. However, unlike Class C shares, Class B
shares convert into Class A shares after the shares have been held for seven
years. After the conversion takes place, the shares will no longer be subject to
a CDSC, and will be subject to the servicing fees charged for Class A shares
which are lower than the distribution and servicing fees charged on either Class
B or Class C shares. See "Deferred Sales Charge Alternative--Class B Shares"
below. Class B shares are not available for purchase by employer sponsored
retirement plans.

Class C Class C shares might be preferred by investors who intend to purchase
shares which are not of sufficient aggregate value to qualify for Class A sales
charges of 1% or less and who wish to have all purchase payments invested
initially. Class C shares are preferable to Class B shares for investors who
intend to maintain their investment for intermediate periods and therefore may
also be preferable for investors who are unsure of the intended length of their
investment. Unlike Class B shares, Class C shares are not subject to a CDSC
after they have been held for one year and are subject to only a 1% CDSC during
the first year. However, because Class C shares do not convert into Class A
shares, Class B shares are preferable to

                                     SG-10
<PAGE>

Class C shares for investors who intend to maintain their investment in the
Funds for long periods. See "Asset Based Sales Charge Alternative--Class C
Shares" below.

         In determining which class of shares to purchase, an investor should
always consider whether any waiver or reduction of a sales charge or a CDSC is
available. See generally "Initial Sales Charge Alternative--Class A Shares" and
"Waiver of Contingent Deferred Sales Charges" below.

         The maximum single purchase of Class B shares of a Fund is $249,999.
The maximum single purchase of Class C shares of a Fund is $999,999. The Funds
may refuse any order to purchase shares.

         For a description of the Distribution and Servicing Plans and
distribution and servicing fees payable thereunder with respect to Class A,
Class B and Class C shares, see "Distributor and Distribution and Servicing
Plans" below.

Waiver of Contingent Deferred Sales Charges The CDSC applicable to Class A and
Class C shares is currently waived for (i) any partial or complete redemption in
connection with (a) required minimum distributions to IRA account owners or
beneficiaries who are age 70 1/2 or older or (b) distributions to participants
in employer-sponsored retirement plans upon attaining age 59 1/2 or on account
of death or disability; (ii) any partial or complete redemption in connection
with a qualifying loan or hardship withdrawal from an employer sponsored
retirement plan; (iii) any complete redemption in connection with a distribution
from a qualified employer retirement plan in connection with termination of
employment or termination of the employer's plan and the transfer to another
employer's plan or to an IRA (with the exception of a Roth IRA); (iv) any
partial or complete redemption following death or disability (as defined in the
Internal Revenue Code) of a shareholder (including one who owns the shares as
joint tenant with his or her spouse) from an account in which the deceased or
disabled is named, provided the redemption is requested within one year of the
death or initial determination of disability; (v) any redemption resulting from
a return of an excess contribution to a qualified employer retirement plan or an
IRA (with the exception of a Roth IRA); (vi) up to 10% per year of the value of
a Fund account which (a) has the value of at least $10,000 at the start of such
year and (b) is subject to an Automatic Withdrawal Plan; (vii) redemptions by
Trustees, officers and employees of either Trust, and by directors, officers and
employees of the Distributor, PIMCO Advisors or Pacific Investment Management
Company; (viii) redemptions effected pursuant to a Fund's right to involuntarily
redeem a shareholder's Fund account if the aggregate net asset value of shares
held in such shareholder's account is less than a minimum account size specified
in such Fund's prospectus; (ix) involuntary redemptions caused by operation of
law; (x) redemptions of shares of any Fund that is combined with another Fund,
investment company, or personal holding company by virtue of a merger,
acquisition or other similar reorganization transaction; (xi) redemptions by a

                                     SG-11
<PAGE>


shareholder who is a participant making periodic purchases of not less than $50
through certain employer sponsored savings plans that are clients of a
broker-dealer with which the Distributor has an agreement with respect to such
purchases; (xii) redemptions effected by trustees or other fiduciaries who have
purchased shares for employer-sponsored plans, the trustee, administrator,
fiduciary, broker, trust company or registered investment adviser for which has
an agreement with the Distributor with respect to such purchases; (xiii)
redemptions in connection with IRA accounts established with Form 5305-SIMPLE
under the Code for which the Trust is the designated financial institution;
(xiv) a redemption by a holder of Class A shares who purchased $1,000,000 or
more of Class A shares (and therefore did not pay a sales charge) where the
participating broker or dealer involved in the sale of such shares waived the
commission it would normally receive from the Distributor pursuant to an
agreement with the Distributor; or (xv) a redemption by a holder of Class A
shares where the participating broker or dealer involved in the purchase of such
shares waived the commission it normally would receive from the Distributor in
connection with such purchase pursuant to an agreement with the Distributor.


         The CDSC applicable to Class B shares is currently waived for any
partial or complete redemption in each of the following cases: (a) in connection
with required minimum distributions to IRA account owners or to plan
participants or beneficiaries who are age 70 1/2 or older; (b) involuntary
redemptions caused by operation of law; (c) redemption of shares of any Fund
that is combined with another Fund, investment company, or personal holding
company by virtue of a merger, acquisition or other similar reorganization
transaction; (d) following death or disability (as defined in the Code) of a
shareholder (including one who owns the shares as joint tenant with his or her
spouse) from an account in which the deceased or disabled is named, provided the
redemption is requested within one year of the death or initial determination of
disability; and (e) up to 10% per year of the value of a Fund account which (i)
has a value of at least $10,000 at the start of such year and (ii) is subject to
an Automatic Withdrawal Plan. See "How to Redeem--Automatic Withdrawal Plan."

         The Distributor may require documentation prior to waiver of the CDSC
for any class, including distribution letters, certification by plan
administrators, applicable tax forms, death certificates, physicians'
certificates, etc.

Initial Sales Charge Alternative--Class A Shares

         Class A shares are sold at a public offering price equal to their net
asset value per share plus a sales charge, as set forth below. As indicated
below under "Class A Deferred Sales Charge," certain investors that purchase
$1,000,000 or more of any Fund's Class A shares (and thus pay no initial sales
charge) may be subject to a 1% CDSC if they redeem such shares during the first
18 months after their purchase.

</TABLE>


1.   As shown, investors that purchase more than $1,000,000 of any Fund's Class
     A shares ($250,000 in the case of the Short-Term Fund) will not pay any
     initial sales charge on such purchase. However, except with regard to
     purchases of Class A shares of the Money Market, California Municipal Bond,
     California Intermediate Municipal Bond and New York Municipal Bond Funds,
     purchasers of $1,000,000 or more ($250,000 in the case of the Short-Term
     Fund) of Class A shares (other than those purchasers described below under
     "Sales at Net Asset Value" where no commission is paid) will be subject to
     a CDSC of 1% if such shares are redeemed during the first 18 months after
     such shares are purchased unless such purchaser is eligible for a waiver of
     the CDSC as described under "Waiver of Contingent Deferred Sales Charges"
     above. See "Class A Deferred Sales Charge" below.

2.   The Distributor will pay a commission to dealers who sell amounts of
     $1,000,000 or more of Class A shares (or who sell Class A shares at net
     asset value to certain employer-sponsored plans as outlined in "Sales at
     Net Asset Value" below) of each of these Funds and the Portfolios (except
     for the 30/70 Portfolio) according to the following schedule: 0.75% of the
     first $2,000,000, 0.50% of amounts from $2,000,001 to $5,000,000, and 0.25%
     of amounts over $5,000,000; and of the 30/70 Portfolio according to the
     following schedule: 0.50% of the first $2,000,000, and 0.25% of amounts
     over $2,000,000.

3.   The Distributor will pay a commission to dealers who sell amounts of
     $1,000,000 ($250,000 in the case of the Short-Term Fund) or more of Class A
     shares (or who sell Class A shares at net asset value to certain
     employer-sponsored plans as outlined in "Sales at Net Asset Value") of each
     of these Funds except for the Money Market Fund (for which no payment is
     made) and the Short-Term and Short Duration Municipal Income Funds,
     according to the following schedule: 0.50% of the first $2,000,000 and
     0.25% of amounts over $2,000,000; and 0.25% of sales of Class A shares of
     the Short-Term and Short Duration Municipal Income Funds in excess of
     $250,000.

4.   The Distributor will pay a commission to dealers who sell $250,000 or more
     of Class A shares of the California Municipal Bond, California Intermediate
     Municipal Bond and New York Municipal Bond Funds at an annual rate of
     0.25%, to be paid in quarterly installments.

     Each Fund receives the entire net asset value of its Class A shares
purchased by investors. The Distributor receives the sales charge shown above
less any applicable discount or commission "reallowed" to participating brokers
in the amounts indicated in the table above. The Distributor may, however, elect
to reallow the entire sales charge to participating brokers for all sales with
respect to which orders are placed with the Distributor for any particular

                                     SG-16
<PAGE>

Fund during a particular period. During such periods as may from time to time be
designated by the Distributor, the Distributor will pay an additional amount of
up to 0.50% of the purchase price on sales of Class A shares of all or selected
Funds purchased to each participating broker which obtains purchase orders in
amounts exceeding thresholds established from time to time by the Distributor.
From time to time, the Distributor, its parent and/or its affiliates may make
additional payments to one or more participating brokers based upon factors such
as the level of sales or the length of time clients' assets have remained in the
Trust.

         Shares issued pursuant to the automatic reinvestment of income
dividends or capital gains distributions are issued at net asset value and are
not subject to any sales charges.

         Under the circumstances described below, investors may be entitled to
pay reduced sales charges for Class A shares.

Combined Purchase Privilege Investors may qualify for a reduced sales charge by
combining purchases of the Class A shares of one or more Funds which offer Class
A shares (together, "eligible PIMCO Funds") into a "single purchase," if the
resulting purchase totals at least $50,000. The term single purchase refers to:

         (i)      a single purchase by an individual, or concurrent purchases,
                  which in the aggregate are at least equal to the prescribed
                  amounts, by an individual, his or her spouse and their
                  children under the age of 21 years purchasing Class A shares
                  of the eligible PIMCO Funds for his, her or their own account;

         (ii)     single purchase by a trustee or other fiduciary purchasing
                  shares for a single trust, estate or fiduciary account
                  although more than one beneficiary is involved; or

         (iii)    a single purchase for the employee benefit plans of a single
                  employer.

         For further information, call the Distributor at 1-800-426-0107 or your
broker.

Cumulative Quantity Discount (Right of Accumulation) A purchase of additional
Class A shares of any eligible PIMCO Fund may qualify for a Cumulative Quantity
Discount at the rate applicable to the discount bracket obtained by adding:

         (i)      the investor's current purchase;

         (ii)     the value (at the close of business on the day of the current
                  purchase) of all Class A shares of any eligible PIMCO Fund
                  held by the investor computed at the maximum offering price;
                  and

                                     SG-17
<PAGE>

         (iii)    the value of all shares described in paragraph (ii) owned by
                  another shareholder eligible to be combined with the
                  investor's purchase into a "single purchase" as defined above
                  under "Combined Purchase Privilege."

         For example, if you owned Class A shares of the Equity Income Fund
         worth $25,000 at the current maximum offering price and wished to
         purchase Class A shares of the Growth Fund worth an additional $30,000,
         the sales charge for the $30,000 purchase would be at the 4.50% rate
         applicable to a single $55,000 purchase of shares of the Growth Fund,
         rather than the 5.50% rate.

Letter of Intent An investor may also obtain a reduced sales charge by means of
a written Letter of Intent, which expresses an intention to invest not less than
$50,000 within a period of 13 months in Class A shares of any eligible PIMCO
Fund(s) other than the Money Market Fund. Each purchase of shares under a Letter
of Intent will be made at the public offering price or prices applicable at the
time of such purchase to a single transaction of the dollar amount indicated in
the Letter. At the investor's option, a Letter of Intent may include purchases
of Class A shares of any eligible PIMCO Fund (other than the Money Market Fund)
made not more than 90 days prior to the date the Letter of Intent is signed;
however, the 13-month period during which the Letter is in effect will begin on
the date of the earliest purchase to be included and the sales charge on any
purchases prior to the Letter will not be adjusted.

         Investors qualifying for the Combined Purchase Privilege described
above may purchase shares of the eligible PIMCO Funds under a single Letter of
Intent. For example, if at the time you sign a Letter of Intent to invest at
least $100,000 in Class A shares of any Fund (other than the Money Market Fund),
you and your spouse each purchase Class A shares of the Growth Fund worth
$30,000 (for a total of $60,000), it will only be necessary to invest a total of
$40,000 during the following 13 months in Class A shares of any of the Funds
(other than the Money Market Fund) to qualify for the 3.50% sales charge on the
total amount being invested (the sales charge applicable to an investment of
$100,000 in any of the Funds other than the Money Market, Short-Term, Low
Duration, Real Return Bond, Short Duration Municipal Income, Municipal Bond,
California Municipal Bond, California Intermediate Municipal Bond, New York
Municipal Bond and StocksPLUS Funds).

         A Letter of Intent is not a binding obligation to purchase the full
amount indicated. The minimum initial investment under a Letter of Intent is 5%
of such amount. Shares purchased with the first 5% of such amount will be held
in escrow (while remaining registered in your name) to secure payment of the
higher sales charge applicable to the shares actually purchased in the event the
full intended amount is not purchased. If the full amount indicated is not
purchased, a sufficient amount of such escrowed shares will be involuntarily
redeemed to pay the additional sales charge applicable to the amount actually
purchased, if necessary. Dividends on escrowed shares, whether paid in cash or
reinvested in additional eligible PIMCO Fund

                                     SG-18
<PAGE>

shares, are not subject to escrow. When the full amount indicated has been
purchased, the escrow will be released.


         If you wish to enter into a Letter of Intent in conjunction with your
initial investment in Class A shares of a Fund, you should complete the
appropriate portion of the account application. If you are a current Class A
shareholder desiring to do so you may obtain a form of Letter of Intent by
contacting the Distributor at 1-800-426-0107 or any broker participating in this
program.

Reinstatement Privilege A Class A shareholder who has caused any or all of his
shares (other than the Money Market Fund shares that were not acquired by
exchanging Class A shares of another Fund) to be redeemed may reinvest all or
any portion of the redemption proceeds in Class A shares of any eligible PIMCO
Fund at net asset value without any sales charge, provided that such
reinvestment is made within 120 calendar days after the redemption or repurchase
date. Shares are sold to a reinvesting shareholder at the net asset value next
determined. See "How Net Asset Value is Determined" in the applicable Retail
Prospectus. A reinstatement pursuant to this privilege will not cancel the
redemption transaction and, consequently, any gain or loss so realized may be
recognized for federal tax purposes except that no loss may be recognized to the
extent that the proceeds are reinvested in shares of the same Fund within 30
days. The reinstatement privilege may be utilized by a shareholder only once,
irrespective of the number of shares redeemed, except that the privilege may be
utilized without limit in connection with transactions whose sole purpose is to
transfer a shareholder's interest in a Fund to his Individual Retirement Account
or other qualified retirement plan account. An investor may exercise the
reinstatement privilege by written request sent to the Distributor or to the
investor's broker.

Sales at Net Asset Value Each Fund may sell its Class A shares at net asset
value without a sales charge to (a) current or retired officers, trustees,
directors or employees of either Trust, PIMCO Advisors, Pacific Investment
Management Company or the Distributor, other affiliates of PIMCO Advisors at the
discretion of PIMCO Advisors, Pacific Investment Management Company or the
Distributor, a parent, brother or sister of any such officer, trustee, director
or employee or a spouse or child of any of the foregoing persons, or any trust,
profit sharing or pension plan for the benefit of any such person and to any
other person if the Distributor anticipates that there will be minimal sales
expenses associated with the sale, (b) current registered representatives and
other full-time employees of participating brokers or such persons' spouses or
for trust or custodial accounts for their minor children, (c) trustees or other
fiduciaries purchasing shares for certain plans sponsored by employers,
professional organizations or associations or charitable organizations, the
trustee, administrator, fiduciary, broker, trust company or registered
investment adviser for which has an agreement with the Distributor, PIMCO
Advisors or Pacific Investment Management Company with respect to such purchases
(including provisions related to minimum levels of investment in the Trust), and
to participants in such plans and their spouses purchasing for their account(s)
or IRAs

                                     SG-19
<PAGE>


(with the exception of Roth IRAs), (d) participants investing through accounts
known as "wrap accounts" established with brokers or dealers approved by the
Distributor where such brokers or dealers are paid a single, inclusive fee for
brokerage and investment management services, (e) client accounts of broker-
dealers or registered investment advisers affiliated with such broker-dealers
with which the Distributor, PIMCO Advisors or Pacific Investment Management
Company has an agreement for the use of a Fund in particular investment products
or programs, (f) accounts for which certain trust companies that may be
affiliated with the Trust or the Fund's Adviser serves as trustee or custodian,
and (g) investors who are investing the proceeds from a redemption of shares of
another open-end investment company (mutual fund) on which the investor paid an
initial sales charge, but only to the extent of such proceeds and only if such
redemption is made within 60 days of such redemption. As described above, the
Distributor will only pay service fees and will not pay any initial commission
or other fees to dealers upon the sale of Class A shares to the purchasers
described in this paragraph except for sales to purchasers described under (c)
in this paragraph.

Notification of Distributor An investor or participating broker must notify the
Distributor whenever a quantity discount or reduced sales charge is applicable
to a purchase and must provide the Distributor with sufficient information at
the time of purchase to verify that each purchase qualifies for the privilege or
discount. Upon such notification, the investor will receive the lowest
applicable sales charge. The quantity discounts described above may be modified
or terminated at any time.

Class A Deferred Sales Charge For all Funds, except the Money Market, California
Municipal Bond, California Intermediate Municipal Bond and New York Municipal
Bond Funds, investors who purchase $1,000,000 ($250,000 in the case of the
Short-Term Fund) or more of Class A shares (and, thus, purchase such shares
without any initial sales charge) may be subject to a 1% CDSC (the "Class A
CDSC") if such shares are redeemed within 18 months of their purchase. The Class
A CDSC does not apply to investors purchasing $1,000,000 ($250,000 in the case
of the Short-Term and Short Duration Municipal Income Funds) or more of any
Fund's Class A shares if such investors are otherwise eligible to purchase Class
A shares without any sales charge because they are described under "Sales at Net
Asset Value" above.

         For purchases subject to the Class A CDSC, a 1% CDSC will apply for any
redemption of such Class A shares that occurs within 18 months of their
purchase. No CDSC will be imposed if the shares redeemed have been acquired
through the reinvestment of dividends or capital gains distributions or if the
amount redeemed is derived from increases in the value of the account above the
amount of purchase payments subject to the CDSC. In determining whether a CDSC
is payable, it is assumed that Class A shares acquired through the reinvestment
of dividends and distributions are redeemed first, and thereafter that Class A
shares that have been held by an investor for the longest period of time are
redeemed first.

         The Class A CDSC does not apply to Class A shares of the Money Market,
California Municipal Bond, California Intermediate Municipal Bond
and New York Municipal Bond

                                     SG-20
<PAGE>

Funds but, if Class A shares of these Funds are purchased in a transaction that,
for any other Fund, would be subject to the CDSC (i.e., a purchase of $1,000,000
($250,000 in the case of the Short-Term and Short Duration Municipal Income
Funds) or more) and are subsequently exchanged for Class A shares of any other
Fund, a Class A CDSC will apply to the shares of the Fund(s) acquired by
exchange for a period of 18 months from the date of the exchange.

         The Class A CDSC is currently waived in connection with certain
redemptions as described above under "Alternative Purchase Arrangements--Waiver
of Contingent Deferred Sales Charges." For more information about the Class A
CDSC, call the Distributor at 1-800-426-0107.

Participating Brokers Investment dealers and other financial intermediaries
provide varying arrangements for their clients to purchase and redeem Fund
shares. Some may establish higher minimum investment requirements than set forth
above. Firms may arrange with their clients for other investment or
administrative services and may independently establish and charge transaction
fees and/or other additional amounts to their clients for such services, which
charges would reduce clients' return. Firms also may hold Fund shares in nominee
or street name as agent for and on behalf of their customers. In such instances,
the Trust's transfer agent will have no information with respect to or control
over accounts of specific shareholders. Such shareholders may obtain access to
their accounts and information about their accounts only from their broker. In
addition, certain privileges with respect to the purchase and redemption of
shares or the reinvestment of dividends may not be available through such firms.
Some firms may participate in a program allowing them access to their clients'
accounts for servicing including, without limitation, transfers of registration
and dividend payee changes; and may perform functions such as generation of
confirmation statements and disbursement of cash dividends. This Guide and the
Retail Prospectuses should be read in connection with such firms' material
regarding their fees and services.

Deferred Sales Charge Alternative--Class B Shares

         Class B shares are sold at their current net asset value without any
initial sales charge. The full amount of an investor's purchase payment will be
invested in shares of the Fund(s) selected. A CDSC will be imposed on Class B
shares if an investor redeems an amount which causes the current value of the
investor's account for a Fund to fall below the total dollar amount of purchase
payments subject to the CDSC, except that no CDSC is imposed if the shares
redeemed have been acquired through the reinvestment of dividends or capital
gains distributions or if the amount redeemed is derived from increases in the
value of the account above the amount of purchase payments subject to the CDSC.

         Class B shares of the Short-Term Fund and the Money Market Fund are not
offered for initial purchase but may be obtained through exchanges of Class B
shares of other Funds. See

                                     SG-21
<PAGE>

"Exchange Privilege" below. Class B shares are not available for purchase by
employer sponsored retirement plans.

         Whether a CDSC is imposed and the amount of the CDSC will depend on the
number of years since the investor made a purchase payment from which an amount
is being redeemed. Purchases are subject to the CDSC according to the following
schedule:


         Years Since Purchase                        Percentage Contingent
         Payment was Made                            Deferred Sales Charge

         *    After the seventh year, Class B shares convert into Class A shares
              as described below.

         In determining whether a CDSC is payable, it is assumed that the
purchase payment from which a redemption is made is the earliest purchase
payment from which a redemption or exchange has not already been fully effected.

         The following example will illustrate the operation of the Class B
CDSC:

         Assume that an individual opens a Fund account and makes a purchase
payment of $10,000 for Class B shares of a Fund and that six months later the
value of the investor's account for that Fund has grown through investment
performance and reinvestment of distributions to $11,000. The investor then may
redeem up to $1,000 from that Fund account ($11,000 minus $10,000) without
incurring a CDSC. If the investor should redeem $3,000 from that Fund account, a
CDSC would be imposed on $2,000 of the redemption (the amount by which the
investor's account for the Fund was reduced below the amount of the purchase
payment). At the rate of 5%, the Class B CDSC would be $100.

         In determining whether an amount is available for redemption without
incurring a CDSC, the purchase payments made for all Class B shares in the
shareholder's account for the particular Fund are aggregated, and the current
value of all such shares is aggregated. Any CDSC imposed on a redemption of
Class B shares is paid to the Distributor.

                                     SG-22
<PAGE>

         Class B shares are subject to higher distribution fees than Class A
shares for a fixed period after their purchase, after which they automatically
convert to Class A shares and are no longer subject to such higher distribution
fees. Class B shares of each Fund automatically convert into Class A shares
after they have been held for seven years.

         For sales of Class B shares made and services rendered to Class B
shareholders, the Distributor intends to make payments to participating brokers,
at the time a shareholder purchases Class B shares, of 4.00% of the purchase
amount for each of the Funds. During such periods as may from time to time be
designated by the Distributor, the Distributor will pay selected participating
brokers an additional amount of up to .50% of the purchase price on sales of
Class B shares of all or selected Funds purchased to each participating broker
which obtains purchase orders in amounts exceeding thresholds established from
time to time by the Distributor.

         The Class B CDSC is currently waived in connection with certain
redemptions as described above under "Alternative Purchase Arrangements --Waiver
of Contingent Deferred Sales Charges." For more information about the Class B
CDSC, call the Distributor at 1-800-426-0107.

Asset Based Sales Charge Alternative--Class C Shares

         Class C shares are sold at their current net asset value without any
initial sales charge. A CDSC is imposed on Class C shares if an investor redeems
an amount which causes the current value of the investor's account for a Fund to
fall below the total dollar amount of purchase payments subject to the CDSC,
except that no CDSC is imposed if the shares redeemed have been acquired through
the reinvestment of dividends or capital gains distributions or if the amount
redeemed is derived from increases in the value of the account above the amount
of purchase payments subject to the CDSC. All of an investor's purchase payments
are invested in shares of the Fund(s) selected.

         Whether a CDSC is imposed and the amount of the CDSC will depend on the
number of years since the investor made a purchase payment from which an amount
is being redeemed. Purchases are subject to the CDSC according to the following
schedule:

         Years Since Purchase                        Percentage Contingent
         Payment was Made                            Deferred Sales Charge
         ----------------                            ---------------------

         First                                                1
         Thereafter                                           0

                                     SG-23
<PAGE>

         In determining whether a CDSC is payable, it is assumed that the
purchase payment from which the redemption is made is the earliest purchase
payment (from which a redemption or exchange has not already been effected).


         The following example will illustrate the operation of the Class C
CDSC:

         Assume that an individual opens a Fund account and makes a purchase
payment of $10,000 for Class C shares of a Fund and that six months later the
value of the investor's account for that Fund has grown through investment
performance and reinvestment of distributions to $11,000. The investor then may
redeem up to $1,000 from that Fund account ($11,000 minus $10,000) without
incurring a CDSC. If the investor should redeem $3,000 from that Fund account, a
CDSC would be imposed on $2,000 of the redemption (the amount by which the
investor's account for the Fund was reduced below the amount of the purchase
payment). At the rate of 1%, the Class C CDSC would be $20.

         In determining whether an amount is available for redemption without
incurring a CDSC, the purchase payments made for all Class C shares in the
shareholder's account for the particular Fund are aggregated, and the current
value of all such shares is aggregated. Any CDSC imposed on a redemption of
Class C shares is paid to the Distributor. Unlike Class B shares, Class C shares
do not automatically convert to any other class of shares of the Funds.

         Except as described below, for sales of Class C shares made and
services rendered to Class C shareholders, the Distributor expects to make
payments to participating brokers, at the time the shareholder purchases Class C
shares, of 1.00% (representing .75% distribution fees and .25% servicing fees)
of the purchase amount for all Funds, except the Money Market, Short-Term,
Real Return Bond, Municipal Bond and StocksPLUS Funds. For the Low Duration,
Real Return Bond, Municipal Bond and StocksPLUS Funds, the Distributor expects
to make payments of .75% (representing .50% distribution fees and .25% service
fees); for the Short-Term Fund, the Distributor expects to make payments of .55%
(representing .30% distribution fees and .25% service fees); and for the Money
Market Fund, the Distributor expects to make no payment. For sales of Class C
shares made to participants making periodic purchases of not less than $50
through certain employer sponsored savings plans which are clients of a broker-
dealer with which the Distributor has an agreement with respect to such
purchases, no payments are made at the time of purchase. During such periods as
may from time to time be designated by the Distributor, the Distributor will pay
an additional amount of up to .50% of the purchase price on sales of Class C
shares of all or selected Funds purchased to each participating broker which
obtains purchase orders in amounts exceeding thresholds established from time to
time by the Distributor.

         The Class C CDSC is currently waived in connection with certain
redemptions as described above under "Alternative Purchase Arrangements--Waiver
of Contingent Deferred

                                     SG-24

Sales Charges." For more information about the Class C CDSC, contact the
Distributor at 1-800-426-0107.



Exchange Privilege

         Except with respect to exchanges for shares of Funds for which sales
may be suspended to new investors or as provided in the applicable Retail
Prospectus or in this Guide, a shareholder may exchange Class A, Class B and
Class C shares of any Fund for the same Class of shares of any other Fund in an
account with identical registration on the basis of their respective net asset
values (except that a sales charge will apply on exchanges of Class A shares of
the Money Market Fund on which no sales charge was paid at the time of
purchase.) Class A shares of the Money Market Fund may be exchanged for Class A
shares of any other Fund, but the usual sales charges applicable to investments
in such other Fund apply on shares for which no sales charge was paid at the
time of purchase. There are currently no exchange fees or charges. All exchanges
are subject to the $2,500 minimum initial purchase requirement for each Fund,
except with respect to tax-qualified programs and exchanges effected through the
PIMCO Funds Auto-Exchange plan. An exchange will constitute a taxable sale for
federal income tax purposes.

         Investors who maintain their account with the Distributor may exchange
shares by a written exchange request sent to PIMCO Funds Distributors LLC, P.O.
Box 9688, Providence, RI 02940-0926 or, unless the investor has specifically
declined telephone exchange privileges on the account application or elected in
writing not to utilize telephone exchanges, by a telephone request to the
Distributor at 1-800-426-0107. Each Trust will employ reasonable procedures to
confirm that instructions communicated by telephone are genuine, and may be
liable for any losses due to unauthorized or fraudulent instructions if it fails
to employ such procedures. Each Trust will require a form of personal
identification prior to acting on a caller's telephone instructions, will
provide written confirmations of such transactions and will record telephone
instructions. Exchange forms are available from the Distributor at
1-800-426-0107 and may be used if there will be no change in the registered name
or address of the shareholder. Changes in registration information or account
privileges may be made in writing to the Transfer Agent, PFPC, Inc., P.O. Box
9688, Providence, RI 02940-0926, or by use of forms which are available from the
Distributor. A signature guarantee is required. See "How to Buy
Shares--Signature Guarantee." Telephone exchanges may be made between 9:00 a.m.,
Eastern time and the close of regular trading (normally 4:00 p.m., Eastern time)
on the New York Stock Exchange on any day the Exchange is open (generally
weekdays other than normal holidays). The Trusts reserve the right to refuse
exchange purchases if, in the judgment of the Fund's Adviser, the purchase would
adversely affect the Fund and its shareholders. In particular, a pattern of
exchanges characteristic of

                                     SG-25
<PAGE>

"market-timing" strategies may be deemed by an Adviser to be detrimental to a
Trust or a particular Fund.

         The Trusts reserve the right to refuse exchange purchases if, in the
judgment of an Adviser or a Fund's sub-adviser, 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 an Adviser to be
detrimental to a Trust or a particular Fund. Currently, each 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 PIMCO Fund, and
then exchanges back into the originally purchased Fund. The Trusts have 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 Trusts have no
current intention of terminating or modifying the exchange privilege other than
as set forth in the preceding sentence, each reserves the right to do so at any
time. Except as otherwise permitted by the Securities and Exchange Commission,
each Trust will give 60 days' advance notice to shareholders of any termination
or material modification of the exchange privilege. For further information
about exchange privileges, contact your participating broker or call the
Distributor at 1-800-426-0107.

         With respect to Class B and Class C shares, or Class A shares subject
to a CDSC, 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. Shareholders should take into account the
effect of any exchange on the applicability of any CDSC that may be imposed upon
any subsequent redemption.

         Investors may also select the PIMCO Funds Auto-Exchange plan which
establishes automatic periodic exchanges. For further information on automatic
exchanges see "How to Buy Shares--PIMCO Funds Auto-Exchange" above.

Exchange Limitations

         Until July 3, 2000, shareholders will not be permitted to exchange
their shares of any Fund or series of the Trusts for shares of the Global
Innovation Fund, although investors will be permitted to exchange their shares
of the Global Innovation Fund for shares of the same class of any other Fund or
series of the Trusts, subject to any restrictions on exchanges in the applicable
Prospectus(es). This restriction may be changed or eliminated at any time at the
discretion of the Distributor.

How to Redeem

         Class A, Class B or Class C shares may be redeemed through a
participating broker, by telephone, by submitting a written redemption request
directly to the Transfer Agent (for non-broker accounts), or through an
Automatic Withdrawal Plan or PIMCO Funds Fund Link.

         A CDSC may apply to a redemption of Class A, Class B or Class C shares.
See "Alternative Purchase Arrangements" above. Shares are redeemed at their net
asset value next determined after a redemption request has been received as
described below, less any applicable CDSC. There is no charge by the Distributor
(other than an applicable CDSC) with respect to a redemption; however, a
participating broker who processes a redemption for an investor may charge
customary commissions for its services (which may vary). Dealers and other
financial services firms are obligated to transmit orders promptly. Requests for
redemption received by dealers or other firms prior to the close of regular
trading (normally 4:00 p.m., Eastern time) on the New York Stock Exchange on a
regular business day and received by the Distributor prior to the close of the
Distributor's business day will be confirmed at the net asset value effective at
the closing of the Exchange on that day, less any applicable CDSC.

         Other than an applicable CDSC, you will not pay any special fees or
charges to the Trust or the Distributor when you sell your shares. However, if
you sell your shares through your broker, dealer or other financial
intermediary, that firm may charge you a commission or other fee for processing
your redemption request.

         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 payments for more than seven days, as permitted by law.


Direct Redemption

         A shareholder's original account application permits the shareholder to
redeem by written request and by telephone (unless the shareholder specifically
elects not to utilize telephone redemptions) and to elect one or more of the
additional redemption procedures described below. A shareholder may change the
instructions indicated on his original account application, or may request
additional redemption options, only by transmitting a written direction to the
Transfer Agent. Requests to institute or change any of the additional redemption
procedures will require a signature guarantee.

                                     SG-27
<PAGE>

         Redemption proceeds will normally be mailed to the redeeming
shareholder within seven days or, in the case of wire transfer or Fund Link
redemptions, sent to the designated bank account within one business day. Fund
Link redemptions may be received by the bank on the second or third business
day. In cases where shares have recently been purchased by personal check,
redemption proceeds may be withheld until the check has been collected, which
may take up to 15 days. To avoid such withholding, investors should purchase
shares by certified or bank check or by wire transfer.

Written Requests

         To redeem shares in writing (whether or not represented by
certificates), a shareholder must send the following items to the Transfer
Agent, PFPC, Inc., P.O. Box 9688, Providence, RI 02940-0926.

(1)      a written request for redemption signed by all registered owners
         exactly as the account is registered on the Transfer Agent's records,
         including fiduciary titles, if any, and specifying the account number
         and the dollar amount or number of shares to be redeemed;

(2)      for certain redemptions described below, a guarantee of all signatures
         on the written request or on the share certificate or accompanying
         stock power, if required, as described under "How to Buy
         Shares--Signature Guarantee";

(3)      any share certificates issued for any of the shares to be redeemed (see
         "Certificated Shares" below); and

(4)      any additional documents which may be required by the Transfer Agent
         for redemption by corporations, partnerships or other organizations,
         executors, administrators, trustees, custodians or guardians, or if the
         redemption is requested by anyone other than the shareholder(s) of
         record.

         Transfers of shares are subject to the same requirements. A signature
guarantee is not required for a redemption requested by and payable to all
shareholders of record for the account that is to be sent to the address of
record for that account. To avoid delay in redemption or transfer, shareholders
having any questions about these requirements should contact the Transfer Agent
in writing or call the Distributor at 1-800-426-0107 before submitting a
request. Redemption or transfer requests will not be honored until all required
documents have been completed by the shareholder and received by the Transfer
Agent. This redemption option does not apply to shares held in broker "street
name" accounts. Shareholders whose shares are held in broker "street name"
accounts must redeem through their broker.

                                     SG-28
<PAGE>

         If the proceeds of the redemption (i) are to be paid to a person other
than the record owner, (ii) are to be sent to an address other than the address
of the account on the Transfer Agent's records or (iii) are to be paid to a
corporation, partnership, trust or fiduciary, the signature(s) on the redemption
request and on the certificates, if any, or stock power must be guaranteed as
described above, except that the Distributor may waive the signature guarantee
requirement for redemptions up to $2,500 by a trustee of a qualified retirement
plan, the administrator for which has an agreement with the Distributor.

Telephone Redemptions

         Each Trust accepts telephone requests for redemption of uncertificated
shares, except for investors who have specifically declined telephone redemption
privileges on the account application or elected in writing not to utilize
telephone redemptions. The proceeds of a telephone redemption will be sent to
the record shareholder at his record address. Changes in account information
must be made in a written authorization with a signature guarantee. See "How to
Buy Shares--Signature Guarantee." Telephone redemptions will not be accepted
during the 30-day period following any change in an account's record address.
This redemption option does not apply to shares held in broker "street name"
accounts. Shareholders whose shares are held in broker "street name" accounts
must redeem through their broker.

         By completing an account application, an investor agrees that the
applicable Trust, the Distributor and the Transfer Agent shall not be liable for
any loss incurred by the investor by reason of the Trust accepting unauthorized
telephone redemption requests for his account if the Trust reasonably believes
the instructions to be genuine. Thus, shareholders risk possible losses in the
event of a telephone redemption not authorized by them. Each Trust may accept
telephone redemption instructions from any person identifying himself as the
owner of an account or the owner's broker where the owner has not declined in
writing to utilize this service. Each Trust will employ reasonable procedures to
confirm that instructions communicated by telephone are genuine, and may be
liable for any losses due to unauthorized or fraudulent instructions if it fails
to employ such procedures. Each Trust will require a form of personal
identification prior to acting on a caller's telephone instructions, will
provide written confirmations of such transactions and will record telephone
instructions.

         A shareholder making a telephone redemption should call the Distributor
at 1-800-426-0107 and state (i) the name of the shareholder as it appears on the
Transfer Agent's records, (ii) his account number with the Trust, (iii) the
amount to be withdrawn and (iv) the name of the person requesting the
redemption. Usually the proceeds are sent to the investor on the next Trust
business day after the redemption is effected, provided the redemption request
is received prior to the close of regular trading (normally 4:00 p.m., Eastern
time) on the New York Stock Exchange that day. If the redemption request is
received after the close of the New

                                     SG-29
<PAGE>

York Stock Exchange, the redemption is effected on the following Trust business
day at that day's net asset value and the proceeds are usually sent to the
investor on the second following Trust business day. Each Trust reserves the
right to terminate or modify the telephone redemption service at any time.
During times of severe disruptions in the securities markets, the volume of
calls may make it difficult to redeem by telephone, in which case a shareholder
may wish to send a written request for redemption as described under "Written
Requests" above. Telephone communications may be recorded by the Distributor or
the Transfer Agent.

Fund Link Redemptions

         If a shareholder has established Fund Link, the shareholder may redeem
shares by telephone and have the redemption proceeds sent to a designated
account at a financial institution. Fund Link is normally established within 45
days of receipt of a Fund Link application by the Transfer Agent. To use Fund
Link for redemptions, call the Distributor at 1-800-426-0107. Subject to the
limitations set forth above under "Telephone Redemptions," the Distributor, a
Trust and the Transfer Agent may rely on instructions by any registered owner
believed to be genuine and will not be responsible to any shareholder for any
loss, damage or expense arising out of such instructions. Requests received by
the Transfer Agent prior to the close of regular trading (normally 4:00 p.m.,
Eastern time) on the New York Stock Exchange on a business day will be processed
at the net asset value on that day and the proceeds (less any CDSC) will
normally be sent to the designated bank account on the following business day
and received by the bank on the second or third business day. If the redemption
request is received after the close of regular trading on the New York Stock
Exchange, the redemption is effected on the following business day. Shares
purchased by check may not be redeemed through Fund Link until such shares have
been owned (i.e., paid for) for at least 15 days. Fund Link may not be used to
redeem shares held in certificated form.

         Changes in bank account information must be made by completing a new
Fund Link application, signed by all owners of record of the account, with all
signatures guaranteed. See "How to Buy Shares--Signature Guarantee." See "How to
Buy Shares--PIMCO Funds Fund Link" for information on establishing the Fund Link
privilege. Either Trust may terminate the Fund Link program at any time without
notice to its shareholders. This redemption option does not apply to shares held
in broker "street name" accounts. Shareholders whose shares are held in broker
"street name" accounts must redeem through their broker.

PIMCO Funds Automated Telephone System

         PIMCO Funds Automated Telephone System ("ATS") is an automated
telephone system that enables shareholders to perform a number of account
transactions automatically using a touch-tone telephone. ATS may be used on
already-established Fund accounts after you obtain a Personal Identification
Number (PIN) by calling the special ATS number: 1-800-223-2413.

                                     SG-30
<PAGE>

Purchasing Shares. You may purchase shares in amounts up to $100,000 by
telephone by calling 1-800-223-2413. You must have established ATS privileges to
link your bank account with the Fund to pay for these purchases.

Exchanging Shares. With the PIMCO Funds Exchange Privilege, you can exchange
shares automatically by telephone from your Fund Link Account to another PIMCO
Funds account you have already established by calling 1-800-223-2413. Please
refer to "Exchange Privilege" for details.

Redemptions. You may redeem shares by telephone automatically by calling
1-800-223-2413 and the Fund will send the proceeds directly to your Fund bank
account. Please refer to "How to Redeem" for details.

Expedited Wire Transfer Redemptions

         If a shareholder has given authorization for expedited wire redemption,
shares can be redeemed and the proceeds sent by federal wire transfer to a
single previously designated bank account. Requests received by a Trust prior to
the close of the New York Stock Exchange will result in shares being redeemed
that day at the next determined net asset value (less any CDSC). Normally the
proceeds will be sent to the designated bank account the following business day.
The bank must be a member of the Federal Reserve wire system. Delivery of the
proceeds of a wire redemption request may be delayed by the applicable Trust for
up to 7 days if the Distributor deems it appropriate under then current market
conditions. Once authorization is on file with a Trust, such Trust will honor
requests by any person identifying himself as the owner of an account or the
owner's broker by telephone at 1-800-426-0107 or by written instructions. A
Trust cannot be responsible for the efficiency of the Federal Reserve wire
system or the shareholder's bank. Neither Trust currently charges for wire
transfers. The shareholder is responsible for any charges imposed by the
shareholder's bank. The minimum amount that may be wired is $2,500. Each Trust
reserves the right to change this minimum or to terminate the wire redemption
privilege. Shares purchased by check may not be redeemed by wire transfer until
such shares have been owned (i.e., paid for) for at least 15 days. Expedited
wire transfer redemptions may be authorized by completing a form available from
the Distributor. Wire redemptions may not be used to redeem shares in
certificated form. To change the name of the single bank account designated to
receive wire redemption proceeds, it is necessary to send a written request with
signatures guaranteed to PIMCO Funds Distributors LLC, P.O. Box 9688,
Providence, RI 02940-0926. See "How to Buy Shares--Signature Guarantee." This
redemption option does not apply to shares held in broker "street name"
accounts. Shareholders whose shares are held in broker "street name" accounts
must redeem through their broker.

                                     SG-31
<PAGE>

Certificated Shares

         To redeem shares for which certificates have been issued, the
certificates must be mailed to or deposited with the applicable Trust, duly
endorsed or accompanied by a duly endorsed stock power or by a written request
for redemption. Signatures must be guaranteed as described under "How to Buy
Shares--Signature Guarantee." Further documentation may be requested from
institutions or fiduciary accounts, such as corporations, custodians (e.g.,
under the Uniform Gifts to Minors Act), executors, administrators, trustees or
guardians ("institutional account owners"). The redemption request and stock
power must be signed exactly as the account is registered, including indication
of any special capacity of the registered owner.

Automatic Withdrawal Plan

         An investor who owns or buys shares of a Fund having a net asset value
of $10,000 or more may open an Automatic Withdrawal Plan and have a designated
sum of money (not less than $100 per Fund) paid monthly (or quarterly) to the
investor or another person. Such a plan may be established by completing the
appropriate section of the account application or by obtaining an Automatic
Withdrawal Plan application from the Distributor or your broker. If an Automatic
Withdrawal Plan is set up after the account is established providing for payment
to a person other than the record shareholder or to an address other than the
address of record, a signature guarantee is required. See "How to Buy
Shares--Signature Guarantee." Class A, Class B and Class C shares of any Fund
are deposited in a plan account and all distributions are reinvested in
additional shares of the particular class of the Fund at net asset value. Shares
in a plan account are then redeemed at net asset value (less any applicable
CDSC) to make each withdrawal payment. Any applicable CDSC may be waived for
certain redemptions under an Automatic Withdrawal Plan. See "Alternative
Purchase Arrangements--Waiver of Contingent Deferred Sales Charges."

         Redemptions for the purpose of withdrawals are ordinarily made on the
business day preceding the day of payment at that day's closing net asset value
and checks are mailed on the day of payment selected by the shareholder. The
Transfer Agent may accelerate the redemption and check mailing date by one day
to avoid weekend delays. Payment will be made to any person the investor
designates; however, if the shares are registered in the name of a trustee or
other fiduciary, payment will be made only to the fiduciary, except in the case
of a profit-sharing or pension plan where payment will be made to the designee.
As withdrawal payments may include a return of principal, they cannot be
considered a guaranteed annuity or actual yield of income to the investor. The
redemption of shares in connection with an Automatic Withdrawal Plan may result
in a gain or loss for tax purposes. Continued withdrawals in excess of income
will reduce and possibly exhaust invested principal, especially

                                     SG-32
<PAGE>

in the event of a market decline. The maintenance of an Automatic Withdrawal
Plan concurrently with purchases of additional shares of the Fund would be
disadvantageous to the investor because of the CDSC that may become payable on
such withdrawals in the case of Class A, Class B or Class C shares and because
of the initial sales charge in the case of Class A shares. For this reason, the
minimum investment accepted for a Fund while an Automatic Withdrawal Plan is in
effect for that Fund is $1,000, and an investor may not maintain a plan for the
accumulation of shares of the Fund (other than through reinvestment of
distributions) and an Automatic Withdrawal Plan at the same time. The Trust or
the Distributor may terminate or change the terms of the Automatic Withdrawal
Plan at any time.

         Because the Automatic Withdrawal Plan may involve invasion of capital,
investors should consider carefully with their own financial advisers whether
the plan and the specified amounts to be withdrawn are appropriate in their
circumstances. The Trust and the Distributor make no recommendations or
representations in this regard.

Redemptions In Kind

         Each Trust agrees to redeem shares of its Funds solely in cash 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, each Trust reserves the right to 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 shares would ever be redeemed in
kind. When shares are redeemed in kind, the redeeming shareholder should expect
to incur transaction costs upon the disposition of the securities received in
the distribution.

Item 24.  Persons Controlled by or Under Common Control with Registrant.

          Not applicable.

Item 25.  Indemnification

     Reference is made to Article VIII, Section 1, of the Registrant's Second
Amended and Restated Agreement and Declaration of Trust, which is incorporated
by reference herein.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (the "Act"), may be permitted to trustees, officers and
controlling persons of the Registrant by the Registrant pursuant to the Trust's
Second Amended and Restated Agreement and Declaration of Trust, its By-Laws 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, 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 the successful defense of any action, suit or
proceeding) is asserted by such trustees, officers or controlling persons in
connection with the securities 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 issue.

Item 26.  Business and Other Connections of Investment Advisor and Portfolio
          Managers.

     Unless otherwise stated, the principal business address of each
organization listed in 800 Newport Center Drive, Newport Beach, CA 92660.
