mance and Fees  objective, principal investments and strategies, principal
                risks, performance information and fees and expenses. A more

                It is possible to lose money on investments in the Funds. An
                investment in a Fund is not a deposit of a bank and is not
                guaranteed or insured by the Federal Deposit Insurance
                Corporation or any other government agency.

            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 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.

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
              . Issuer Risk                 . Credit Risk
              . Value Securities Risk       . Management Risk

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

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

            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

              Fund Category              40-50
              Value Stocks


            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in income-producing (or
            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               .Credit Risk
              .Issuer Risk               .Management Risk
              .Value Securities 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
            (1/20/97), 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.

            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

              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 dominant
            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 sells stocks when the portfolio manager believes that
            earnings, sentiment and relative performance are disappointing or
            if an alternative investment is more attractive.

             The Fund may also invest 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, usually
            in the form of 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
             .Growth Securities 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 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 Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of companies
            which utilize 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. 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 dominant 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 sells stocks when the portfolio
            manager believes that earnings, sentiment and relative performance
            are disappointing or if an alternative investment is more
            attractive.

             The Fund may also invest 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, usually
            in the form of 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
              .Concentration Risk     .Foreign Investment Risk  .Management Risk
              .Growth Securities 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 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.

                       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            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
                       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. The
                       Fund had different sub-advisers during the periods prior
                       to November 15, 1994, 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.

                C shares, a 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.

            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 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.

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.

            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 $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 dominant
            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 sells stocks when the portfolio manager believes that
            earnings, sentiment and relative performance are disappointing or
            if an alternative investment is more attractive.

             The Fund may also invest 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, usually
            in the form of 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.

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

            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.

            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 a global portfolio of
            common stocks of companies principally engaged in precious metals-
            related activities, including mining, processing, distribution and
            marketing of precious metals. A company is deemed to be
            "principally engaged" in precious metals-related activities if at
            the time of investment at least 50% of the company's assets,
            revenues or profits are derived from precious metals industries.
            The Fund may invest up to 100% of its assets in companies whose
            activities relate to a single precious metal, such as gold.
            Although the Fund reserves the right to do so at any time, it does
            not presently intend to invest more than 10% of its assets
            directly in precious metals (such as gold bullion). Because the
            Fund concentrates investments in precious metals-related
            companies, it is intended for aggressive investors and is not
            intended as a complete investment program.

              The Fund normally invests a substantial portion of its assets in
            foreign securities of developed and emerging markets issuers,
            including securities which trade primarily in currencies other
            than the U.S. dollar, and may concentrate investments in
            particular foreign countries or regions, such as Canada, South
            Africa or Australia.

              In making investment decisions for the Fund, the portfolio
            manager analyses economic factors (such as current and expected
            growth in the equity and fixed income markets, forecasts for
            interest rates and inflation, and stability in the currency
            markets) to identify precious metals and related industry groups
            that he believes will perform well under current and future
            economic conditions. The portfolio manager then selects individual
            stocks that appear to be undervalued relative to stocks of other
            companies in the same precious metals industry group. He also
            considers company fundamentals, such as strength and depth of
            management, financial stability, labor and production costs,
            access to inventory, and research and development capabilities
            (including those relating to exploration and mining activities).
            The portfolio manager sells a stock when its relative valuation
            becomes excessive or when the company's fundamentals appear to be
            deteriorating.

              The Fund may invest in equity securities other than common
            stocks, including preferred stocks and convertible securities. 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
            may also hold a significant portion of its assets in cash and
            high-quality fixed income securities in order to satisfy
            anticipated liquidity requirements.

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 (6/15/95), 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. 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.

            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.To achieve income, the Fund invests a portion
            of its assets in income-producing (or 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 sells 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 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, usually
            in the form of 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  . Credit Risk
              . Issuer Risk              Risk                . Management Risk
              . Value Securities Risk  . Currency Risk


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

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

            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

            $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 Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of companies
            with smaller 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 $100 million, but excluding the 1,000
            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.

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
            A, B or C shares during the periods listed. Although Institutional
            Class and Class A, B and C shares would have similar annual
            returns (because all of 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. 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 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.

- --------------------------------------------------------------------------------
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
              .Value Securities 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
            (1/20/97), 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.

                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.

            industry or the market as a whole), high profitability and
            consistent, predictable earnings. In addition, through fundamental
            research, the portfolio managers seek to identify dominant
            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 sells stocks when the portfolio managers believe that
            earnings, sentiment and relative performance are disappointing or
            if an alternative investment is more attractive.

             The Fund may also invest 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, usually
            in the form of 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.

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.

               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 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 superior 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 sells 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.

            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 $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 (or 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
            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                   .Credit Risk
              .Issuer Risk                   .Management Risk
              .Value Securities 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. 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 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 (or 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 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 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
            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      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       Each Fund may invest in companies that may not be expected to
Securities  experience significant earnings growth, but whose securities its
Risk        portfolio manager believes are selling at a price lower than their
            true value. The Capital Appreciation, Equity Income, Mid-Cap
            Growth, Renaissance, Small-Cap Growth, Small-Cap Value, Value and
            Value 25 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.

Growth      Each Fund may invest in equity securities of companies that its
Securities  portfolio manager believes will experience relatively rapid
Risk        earnings growth. The Capital Appreciation, Growth, Innovation,
            Mid-Cap Growth, Opportunity, Small-Cap Growth and Target 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.

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 Opportunity, Small-Cap Growth and Small-Cap Value Funds
            generally have substantial exposure to this risk. The Mid-Cap
            Growth, Target and Value 25 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.

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, Equity Income, Mid-Cap
Risk           Growth, Small-Cap Growth, Small-Cap Value, Value and Value 25
               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.

Foreign        A Fund that invests in foreign securities, and particularly the
Investment     International and Precious Metals Funds, may experience more
Risk           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 International
               Fund or Precious Metals Fund, invests a significant portion of
               its assets in a concentrated geographic area like 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 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
Risk           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 International and
               Precious Metals Funds may invest significant portions of their
               assets in emerging market securities.

Currency       Funds that invest directly in foreign currencies or in securities
Risk           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 International and Precious Metals
               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.

Concentration  Concentration of investments in a small number of issuers,
Risk           industries or foreign currencies increases risk. Funds such as
               the Value 25 Fund that invest in a relatively small number of
               issuers are more susceptible to risks associated with a single
               economic, political or regulatory occurrence than a more
               diversified Fund might be. Some of those issuers also may present
               substantial credit or other risks. The International and Precious
               Metals Funds may be subject to this risk to the extent that they
               concentrate their assets in securities denominated in a
               particular foreign currency or in a concentrated geographic area
               outside the U.S. Similarly, the Precious Metals Fund is
               vulnerable to events adversely affecting the precious metals
               industries because it concentrates its assets in those
               industries. Based on historical

                                                                   Prospectus 36

<PAGE>

            experience, the prices of precious metals and of securities of
            companies engaged in precious metals-related activities may be
            subject to extreme fluctuations, reflecting wider economic or
            political instability or for other reasons. Also, the 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.

Leveraging  Certain Funds may engage in transactions or purchase instruments
Risk        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. 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 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. As interest rates rise, the
            value of fixed income securities in a Fund's portfolio are likely to
            decrease.

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.

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         "Administrator") for the Funds. Subject to the supervision of the
Adminis-    Board of Trustees, PIMCO Advisors is responsible for managing,
trator      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, 1999, PIMCO Advisors and its subsidiary partnerships
            had more than $256 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 Growth, Innovation, Opportunity, Renaissance and Target 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, 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
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.

             The Tax-Efficient Equity and Value 25 Funds were not operational
            during the entire fiscal year ended June 30, 1999. The annual
            investment advisory fee rates payable by these Funds are as
            follows (stated as a percentage of the average daily net assets of
            each Fund taken separately): Tax-Efficient Equity--0.45%; Value
            25--0.50%.

Adminis-    Each Fund pays for the administrative services it requires under a
trative     fee structure which is essentially fixed. Class A, Class B and
Fees        Class C 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 Class A, Class B and Class C shareholders and also bears the
            costs of various third-party services required by the Funds,
            including audit, custodial, portfolio accounting, legal, transfer
            agency and printing costs. The result of this fee structure is an
            expense level for Class A, Class B and Class C shareholders of
            each Fund that, with limited exceptions, is precise and
            predictable under ordinary circumstances.

             For the fiscal year ended June 30, 1999, Class A, B and C
            shareholders of the Funds paid 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):

            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.

- --------------------------------------------------------------------------------
Initial     Unless you are eligible for a waiver, the public offering price
Sales       you pay when you buy Class A shares of the Funds is the net asset
Charges--   value ("NAV") of the shares plus an initial sales charge. The
Class A     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.

                                                                   Prospectus 42

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.

            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

             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 International and Precious Metals Funds may not take place
            contemporaneously with the determination of the prices of foreign
            securities used in NAV calculations.

                                                                   Prospectus 44
<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, generally based upon recommendations provided by PIMCO
            Advisors and/or the relevant Sub-Adviser. 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
holders'    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.

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. 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.

Exchanging  You may exchange your Class A, Class B or Class C shares of any
Shares      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,

             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, First Data Investor
            Services Group, 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, and
            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

47  PIMCO Funds: Multi-Manager Series
<PAGE>

             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.

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 had agreed to redeem shares of each Fund solely in cash
In Kind     up to the lesser of $250,000 or 1% of the Fund's net assets during
            any 90-day period for any one shareholder. In consideration of the
            best interests of the remaining shareholders, the Trust may pay
            any redemption proceeds exceeding this amount in whole or in part
            by a distribution in kind of securities held by a Fund in lieu of
            cash. Except for Funds with a tax-efficient management strategy,
            it is highly unlikely that your shares would ever be 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,
            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 be revised in the future to permit it to
            reject signature guarantees from Eligible Guarantor Institutions
            that do not, based on credit guidelines, satisfy such written
            standards or procedures. 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.

            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

                                                                  Prospectus 48
<PAGE>

             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

49  PIMCO Funds: Multi-Manager Series
<PAGE>

            be taxed as capital gains (i.e., on investments owned for more
            than 12 months). 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 International and Precious
            Metals 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       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 Growth, Small-Cap Growth 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 Equity Income, Small-Cap Value,
            Value and Value 25 Funds each intend to be fully invested in
            common stocks (aside from cash management practices), except that
            each of these 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. The Growth, Innovation,
            International, Opportunity, Precious Metals, Renaissance and
            Target 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 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.

                                                                   Prospectus 50
<PAGE>

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, Small-Cap Growth and Small-Cap
Market      Value Funds invest primarily in smaller companies and are
Capitali-   especially sensitive to the risks described below. The Mid-Cap
zations     Growth, Target and Value 25 Funds also have significant exposure
            to these risks because they invest primarily in companies with
            medium-sized market capitalizations, which are smaller 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     The International Fund normally invests principally in securities
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 Precious
            Metals Fund also normally invests a substantial portion of its
            assets (up to 100%) in foreign securities and the Growth,
            Innovation, Opportunity, Renaissance and Target Funds may invest
            up to 15% of their respective assets in foreign securities.

             All of the Funds may invest in American Depository Receipts
            ("ADRs"). In addition, the Growth, Innovation, International,
            Opportunity, Precious Metals, Renaissance and Target 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
            International and Precious Metals 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 International and Precious Metals Funds may invest
            a 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     A Fund that invests directly in foreign currencies or in
Currencies  securities that trade in, and receive revenues in, foreign
            currencies will be subject to currency risk. The International and
            Precious Metals 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. 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 Growth, Innovation,
            International, Opportunity, Precious Metals, Renaissance and
            Target Funds may enter into forward foreign currency exchange
            contracts to reduce the risks of adverse changes in foreign
            exchange rates. In addition, the International and Precious Metals
            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

                                                                   Prospectus 52
<PAGE>

            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 International Fund 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
            International Fund may use one currency (or a basket of
            currencies) to hedge against adverse changes in the value of
            another currency (or a basket of currencies) when exchange rates
            between the two currencies are positively correlated. The Fund
            will segregate assets determined to be liquid by PIMCO 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.

Convertible Each Fund may invest in convertible securities. Convertible
Securities  securities are generally preferred stocks and other securities,
            including fixed income securities and warrants, that are
            convertible into or exercisable for common stock at 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 and 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.

Derivatives Each Fund (except the Capital Appreciation, Equity Income, Mid-Cap
            Growth, Small-Cap Growth, Small-Cap Value, Value and Value 25
            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.

             Examples of derivative instruments include options contracts,
            futures contracts, options on futures contracts and swap
            agreements. The Growth, Innovation, International, Opportunity,
            Precious Metals, Renaissance, Target and Tax-Efficient Equity
            Funds may purchase and sell (write) call and put options on
            securities, securities indexes and foreign currencies. The
            Precious Metals Fund may also purchase and write options on
            commodities indexes. Each of these Funds may purchase and sell
            futures contracts and options thereon with respect to securities,
            securities indexes and foreign currencies. The Precious Metals
            Fund may use futures contracts and related options on precious
            metals (such as gold). The Tax-Efficient Equity Fund 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.

53  PIMCO Funds: Multi-Manager Series
<PAGE>

             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.

Precious    The Precious Metals Fund concentrates its investments in the
Metals      securities of companies in precious metals industries. Prices of
            precious metals can be expected to respond to changes in rates of
            inflation and to perceptions of economic and political
            instability. The values of companies engaged in precious metals-
            related activities whose securities are principally traded on
            foreign securities exchanges may also be affected by changes in
            the exchange rate between the relevant foreign currency and the
            U.S. dollar. Based on historical experience, the prices of
            precious metals and of securities of companies engaged in precious
            metals-related activities may be subject to extreme fluctuations,
            reflecting wider economic or political instability or for other
            reasons.

                                                                   Prospectus 54
<PAGE>

Equity-     The International Fund may invest up to 5% of its assets in
Linked      equity-linked securities. Equity-linked securities are privately
Securities  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.

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
Transac-    settlement date. This risk is in addition to the risk that the
tions       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.

Portfolio   With the exception of the Tax-Efficient Equity Fund, the length of
Turnover    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

55  PIMCO Funds: Multi-Manager Series
<PAGE>

            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.

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 Fund may invest up to 10% of its assets in
in Other    securities of other investment companies, such as closed-end
Investment  management investment companies, or in pooled accounts or other
Companies   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.

Year 2000   Many of the services provided to the Funds depend on the smooth
Readiness   functioning of computer systems. Many systems in use today cannot
Disclosure  distinguish between the year 1900 and the year 2000. Should any of
            the service systems fail to process information properly, this
            could have an adverse impact on the Funds' operations and services
            provided to shareholders. PIMCO Advisors and its subsidiaries have
            surveyed the Funds' material service providers and believe that,
            on the basis of the information supplied, the service providers
            used by the Funds on January 1, 2000 will not be materially
            adversely affected by the so-called "year 2000 problem." However,
            there can be no assurance that the problem will be corrected in
            all respects and that the Funds' operations and services provided
            to shareholders will not be adversely affected, nor can there be
            any assurance that the year 2000 problem will not have an adverse
            effect on the entities whose securities are held by the Funds or
            on domestic or global equity markets or economies, generally.
            Accordingly, PIMCO Advisors and the Sub-Advisers reserve the right
            to vary, during the fourth quarter of 1999 and/or the first
            quarter of 2000, the investments of any Fund to maintain
            sufficient liquidity to satisfy actual or anticipated redemption
            activity.

Changes     The investment objective of each of the Growth, Innovation,
in          International, Opportunity, Precious Metals, Renaissance, Target,
Investment  Tax-Efficient Equity and Value 25 Funds described in this
Objectives  Prospectus may be changed by the Board of Trustees without
and         shareholder approval. The investment objective of each other Fund
Policies    is fundamental and may not be changed 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  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, Precious Metals, 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 Small-
            Cap Growth Fund did not offer Class A, B or C shares during the
            periods shown.

                                   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 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 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.

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
              . Issuer Risk          . Credit Risk
              . Value Securities Risk. Management Risk

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

- --------------------------------------------------------------------------------
Performance The top of the next page shows summary performance information for
Information the Fund in a bar chart and an Average Annual Total Returns table.
            The information provides some indication of the risks of investing
            in the Fund by showing changes in its performance from year to
            year and by showing how the Fund's average annual returns compare
            with the returns of a broad-based securities market index and an
            index of similar funds. The bar chart, the information to its
            right and the Average Annual Total Returns table show performance
            of the Fund's Institutional Class shares, which are offered in a
            different prospectus. This is because the Fund has not offered
            Class D shares for a full calendar year. Although Class D and
            Institutional Class shares would have similar annual returns
            (because all the Fund's shares represent interests in the same
            portfolio of securities), Class D performance would be lower than
            Institutional Class performance because of the higher expenses
            paid by Class D shares.

             The Average Annual Total Returns table also shows estimated
            historical performance for Class D shares. Prior to the inception
            of Class D shares (4/8/98), the 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. 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--Investment Adviser and
                Administrator--Administrative Fees" for details. The Fund
                intends to treat any fees paid under the plan as "service
                fees" for purposes of applicable rules of the National
                Association of Securities Dealers, Inc. (the "NASD"). To the
                extent that such fees are deemed not to be "service fees,"
                Class D shareholders may, depending on the length of time the
                shares are held, pay more than the economic equivalent of the
                maximum front-end sales charges permitted by relevant rules of
                the NASD.
            (2) Other Expenses reflects the portion of the Administrative Fee
                paid by the class that 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.

              Category

</TABLE>


            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in income-producing (or
            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 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           .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 top of the next page shows summary performance information for
Information the Fund in a bar chart and an Average Annual Total Returns table.
            The information provides some indication of the risks of investing
            in the Fund by showing changes in its performance from year to
            year and by showing how the Fund's average annual returns compare
            with the returns of a broad-based securities market index and an
            index of similar funds. The bar chart, the information to its
            right and the Average Annual Total Returns table show performance
            of the Fund's Institutional Class shares, which are offered in a
            different prospectus. This is because the Fund has not offered
            Class D shares for a full calendar year. Although Class D and
            Institutional Class shares would have similar annual returns
            (because all the Fund's shares represent interests in the same
            portfolio of securities), Class D performance would be lower than
            Institutional Class performance because of the higher expenses
            paid by Class D shares.

             The Average Annual Total Returns table also shows estimated
            historical performance for Class D shares. Prior to the inception
            of Class D shares (4/8/98), the 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. 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--Investment Adviser and
                Administrator--Administrative Fees" for details. The Fund
                intends to treat any fees paid under the plan as "service
                fees" for purposes of applicable rules of the National
                Association of Securities Dealers, Inc. (the "NASD"). To the
                extent that such fees are deemed not to be "service fees,"
                Class D shareholders may, depending on the length of time the
                shares are held, pay more than the economic equivalent of the
                maximum front-end sales charges permitted by relevant rules of
                the NASD.

                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.

            industry or the market as a whole), high profitability and
            consistent, predictable earnings. In addition, through fundamental
            research, the portfolio manager seeks to identify dominant
            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 sells stocks when the portfolio manager believes that
            earnings, sentiment and relative performance are disappointing or
            if an alternative investment is more attractive.

             The Fund may also invest 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, usually
            in the form of 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.

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 did not offer Class D shares
            during the periods listed. 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.

             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.

            (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--Investment Adviser and
                Administrator--Administrative Fees" for details. The Fund
                intends to treat any fees paid under the plan as "service
                fees" for purposes of applicable rules of the National
                Association of Securities Dealers, Inc. (the "NASD"). To the
                extent that such fees are deemed not to be "service fees,"
                Class D shareholders may, depending on the length of time the
                shares are held, pay more than the economic equivalent of the
                maximum front-end sales charges permitted by relevant rules of
                the NASD.
            (2) Other Expenses reflects the portion of the Administrative Fee
                paid by the class that is not reflected under Distribution
                and/or Service (12b-1) Fees.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class D shares of the Fund with the costs of
            investing in other mutual funds. The Examples assume that you
            invest $10,000 in 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>      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 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. 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 dominant 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 sells stocks when the portfolio
            manager believes that earnings, sentiment and relative performance
            are disappointing or if an alternative investment is more
            attractive.

             The Fund may also invest 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, usually
            in the form of 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          .Smaller Company Risk .Currency Risk
              .Issuer Risk          .Liquidity Risk       .Credit Risk

            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 Class D
            shares for a full calendar year. Although Class D and Class A
            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 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. It they did, the

            performance figures for Class A shares in the Average Annual Total
            Returns table reflect the impact of sales charges.

             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 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.

                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--Investment Adviser and
                Administrator--Administrative Fees" for details. The Fund
                intends to treat any fees paid under the plan as "service
                fees" for purposes of applicable rules of the National
                Association of Securities Dealers, Inc. (the "NASD"). To the
                extent that such fees are deemed not to be "service fees,"
                Class D shareholders may, depending on the length of time the
                shares are held, pay more than the economic equivalent of the
                maximum front-end sales charges permitted by relevant rules of
                the NASD.

            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.

            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 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.

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

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

             The Average Annual Total Returns table also shows estimated
            historical performance for Class D shares. Prior to the inception
            of Class D shares (4/8/98), the 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. Past performance is no
            guarantee of future results.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class D shares of the Fund with the costs of
            investing in other mutual funds. The Examples assume that you
            invest $10,000 in 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. To achieve income, the Fund invests a portion
            of its assets in income-producing (or 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 sells 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 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, usually
            in the form of 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 Investment Risk
                                                          .Credit Risk
              .Issuer Risk          .Currency Risk        .Management Risk
              .Value Securities 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 C shares, which are offered in a different
            prospectus. This is because the Fund has not offered Class D
            shares for a full calendar year. Although Class D and Class C
            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 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). It 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.

             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 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--Investment Adviser and
                Administrator--Administrative Fees" for details. The Fund
                intends to treat any fees paid under the plan as "service
                fees" for purposes of applicable rules of the National
                Association of Securities Dealers, Inc. (the "NASD"). To the
                extent that such fees are deemed not to be "service fees,"
                Class D shareholders may, depending on the length of time the
                shares are held, pay more than the economic equivalent of the
                maximum front-end sales charges permitted by relevant rules of
                the NASD.
            (2) Other Expenses reflects the portion of the Administrative Fee
                paid by the class that is not reflected under Distribution
                and/or Service (12b-1) Fees.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class D shares of the Fund with the costs of
            investing in other mutual funds. The Examples assume that you
            invest $10,000 in 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.

            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 superior 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 sells 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.

            (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--Investment Adviser and
                Administrator--Administrative Fees" for details. The Fund
                intends to treat any fees paid under the plan as "service
                fees" for purposes of applicable rules of the National
                Association of Securities Dealers, Inc. (the "NASD"). To the
                extent that such fees are deemed not to be "service fees,"
                Class D shareholders may, depending on the length of time the
                shares are held, pay more than the economic equivalent of the
                maximum front-end sales charges permitted by relevant rules of
                the NASD.
            (2) Other Expenses reflects the portion of the Administrative Fee
                paid by the class that is not reflected under Distribution
                and/or Service (12b-1) Fees.

            Examples. The Examples are intended to help you compare the cost
            of investing in Class D shares of the Fund with the costs of
            investing in other mutual funds. The Examples assume that you
            invest $10,000 in 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 $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 (or 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
            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         . Credit Risk
              . Issuer Risk         . Management Risk
              . Value Securities Risk

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

- --------------------------------------------------------------------------------
Performance The top of the next page shows summary performance information for
Information the Fund in a bar chart and an Average Annual Total Returns table.
            The information provides some indication of the risks of investing
            in the Fund by showing changes in its performance from year to
            year and by showing how the Fund's average annual returns compare
            with the returns of a broad-based securities market index and an
            index of similar funds. The bar chart, the information to its
            right and the Average Annual Total Returns table show performance
            of the Fund's Institutional Class shares, which are offered in a
            different prospectus. This is because the Fund has not offered
            Class D shares for a full calendar year. Although Class D and
            Institutional Class shares would have similar annual returns
            (because all the Fund's shares represent interests in the same
            portfolio of securities), Class D performance would be lower than
            Institutional Class performance because of the higher expenses
            paid by Class D shares.

             The Average Annual Total Returns table also shows estimated
            historical performance for Class D shares. Prior to the inception
            of Class D shares (4/8/98), the 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. Past performance is no
            guarantee of future results.

            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       Each Fund may invest in companies that may not be expected to
Securities  experience significant earnings growth, but whose securities its
Risk        portfolio manager believes are selling at a price lower than their
            true value. The Capital Appreciation, Equity Income, Mid-Cap
            Growth, Renaissance and Value 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.

Growth      Each Fund may invest in equity securities of companies that its
Securities  portfolio manager believes will experience relatively rapid
Risk        earnings growth. The Capital Appreciation, Growth, Mid-Cap Growth
            and Innovation 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.

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 Mid-Cap Growth Fund has significant exposure to this risk
            because it invests primarily 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.

Derivatives
Risk
            The Growth, Innovation, Renaissance and Tax-Efficient Equity 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

21 PIMCO Funds: Multi-Manager Series
<PAGE>

            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.

Foreign     A Fund that invests in foreign securities may experience more
Investment  rapid and extreme changes in value than Funds that invest
Risk        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 invests a significant portion of its assets in a
            concentrated geographic area like Eastern Europe, South Africa, or
            Asia, 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.

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

Currency    Funds that invest directly in foreign currencies and in securities
Risk        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. 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.

Concentration
Risk
            Concentration of investments in a small number of issuers,
            industries or foreign currencies increases risk. To the extent
            that a Fund invests in a relatively small number of issuers it
            will be more susceptible to risks associated with a single
            economic, political or regulatory occurrence than a more
            diversified Fund might be. Some of those issuers also may present
            substantial credit or other risks. The 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.

Leveraging  Certain Funds may engage in transactions or purchase instruments
Risk        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. 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 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

                                                                   Prospectus 22
<PAGE>

            as bonds and notes. As interest rates rise, the value of fixed
            income securities in a Fund's portfolio are likely to decrease.

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.

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
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, 1999, PIMCO Advisors and its subsidiary
            partnerships had more than $256 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 Growth, Innovation and Renaissance 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, 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, 1999, 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):

         Innovation Fund                                              0.65%
</TABLE>

             The Tax-Efficient Equity Fund was not operational during the
            entire fiscal year ended June 30, 1999. The annual investment
            advisory fee rate payable by the Tax-Efficient Equity Fund is
            0.45%, 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 various third-party services required by the Funds,
            including audit, custodial, portfolio accounting, legal, transfer
            agency and printing costs. The result of this fee structure is an
            expense level for Class D shareholders of each Fund that, with
            limited exceptions, is precise and predictable under ordinary
            circumstances.

             PIMCO 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).

             For the fiscal year ended June 30, 1999, Class D shareholders of
            the Funds paid 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% 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. 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% Administrative Fees rate under two separate
             columns entitled "Distribution and/or Service (12b-1) Fees"
             (0.25%) and "Other Expenses" (0.40%).

             The Growth and Tax-Efficient Equity Funds did not offer Class D
            shares during the entire fiscal year ended June 30, 1999. Class D
            shareholders of each of these Funds pay administrative fees at the
            annual rate of 0.65%, stated as a percentage of the average daily
            net assets attributable in the aggregate to the Fund's Class D
            shares.

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

Disbributor
            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.

            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

                                                                   Prospectus 26
<PAGE>

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

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

27 PIMCO Funds: Multi-Manager Series
<PAGE>

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

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

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

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

             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  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  You may exchange your Class D shares of any Fund for Class D
Shares      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

                                                                   Prospectus 28
<PAGE>

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

              . 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 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., on investments owned for more than 12
            months). 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.

             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.

                                                                   Prospectus 30

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 Growth 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 conditions, the Equity Income and Value Funds each
            intend to be fully invested in common stocks (aside from cash
            management practices), except that each of these 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. The Growth, Innovation and
            Renaissance 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 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 Mid-Cap Growth Fund has significant exposure
            to the risks described below because it invests primarily in
            companies with medium-sized market capitalizations, which are
            smaller 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
Securities
            The Growth, Innovation and Renaissance 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").

             All of the Funds may invest in American Depository Receipts
            ("ADRs"). In addition, the Growth, Innovation and Renaissance
            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

31 PIMCO Funds: Multi-Manager Series
<PAGE>

            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 countries with developing (or
Securities  "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     A Fund that invests directly in foreign currencies or in
Currencies  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.

             Foreign Currency Transactions. The Growth, Innovation and
            Renaissance Funds may enter into forward foreign currency exchange
            contracts to reduce the risks of adverse changes in foreign
            exchange rates. 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

                                                                   Prospectus 32
<PAGE>

            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.

Convertible Each Fund may invest in convertible securities. Convertible
Securities  securities are generally preferred stocks and other securities,
            including fixed income securities and warrants, that are
            convertible into or exercisable for common stock at 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 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.

Derivatives Each Fund (except the Capital Appreciation, Equity Income, Mid-Cap
            Growth and 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.

             Examples of derivative instruments that the Funds may use include
            options contracts, futures contracts, options on futures contracts
            and swap agreements. The Growth, Innovation, Renaissance and Tax-
            Efficient Equity 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 Tax-Efficient Equity Fund 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.

33 PIMCO Funds: Multi-Manager Series
<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.

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
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

                                                                   Prospectus 34
<PAGE>

            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.

Portfolio   With the exception of the Tax-Efficient Equity Fund, the length of
Turnover    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.

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

35 PIMCO Funds: Multi-Manager Series
<PAGE>

            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 other
in Other    investment companies. As a shareholder of an investment company, a
Investment  Fund may indirectly bear service and other fees which are in
Companies   addition to the fees the Fund pays its service providers.

Year 2000   Many of the services provided to the Funds depend on the smooth
Readiness   functioning of computer systems. Many systems in use today cannot
Disclosure  distinguish between the year 1900 and the year 2000. Should any of
            the service systems fail to process information properly, this
            could have an adverse impact on the Funds' operations and services
            provided to shareholders. PIMCO Advisors and its subsidiaries have
            surveyed the Funds' material service providers and believe that,
            on the basis of the information supplied, the service providers
            used by the Funds on January 1, 2000 will not be materially
            adversely affected by the so-called "year 2000 problem." However,
            there can be no assurance that the problem will be corrected in
            all respects and that the Funds' operations and services provided
            to shareholders will not be adversely affected, nor can there be
            any assurance that the year 2000 problem will not have an adverse
            effect on the entities whose securities are held by the Funds or
            on domestic or global equity markets or economies, generally.
            Accordingly, PIMCO Advisors and the Sub-Advisers reserve the right
            to vary, during the fourth quarter of 1999 and/or the first
            quarter of 2000, the investments of any Fund to maintain
            sufficient liquidity to satisfy actual or anticipated redemption
            activity.

Changes     The investment objective of each of the Growth, Innovation,
in          Renaissance and Tax-Efficient Equity Funds described in this
Investment  Prospectus may be changed by the Board of Trustees without

Policies    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.

            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 Fund did not offer Class D shares during
            the periods shown.

            The Fund seeks to achieve its investment objectie 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. To achieve income, the Fund invests a portion
            of its assets in income-producing (or 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 sells 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 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, usually
            in the form of 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

            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 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.

            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 dominant
            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 sells stocks when the portfolio manager believes that
            earnings, sentiment and relative performance are disappointing or
            if an alternative investment is more attractive.

             The Fund may also invest 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, usually
            in the form of 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
              . Growth Securities
                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 C shares, which are offered in a different
            prospectus. This is because the Fund did not offer Institutional
            Class or Administrative Class shares during the periods shown.
            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. 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 Class C performance
            has been adjusted to reflect that there are no sales charges and
            lower distribution and/or service (12b-1 fees) 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.

</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 $10 billion at the time
            of investment. To achieve income, the Fund invests a portion of
            its assets in income-producing (or dividend-paying) stocks.

             The Fund usually invests in approximately 40 common stocks. The
            Fund attempts to achieve a higher total return performance than
            the S&P 500 Index over a reasonable measurement period. In
            selecting stocks, the portfolio managers use two distinct
            investment disciplines. Approximately 50% of the value of the
            Fund's portfolio will be selected using a "Growth" style. The
            portfolio manager of this Growth segment seeks to identify
            companies with well-defined "wealth creating" characteristics,
            including superior earnings growth, high profitability and
            consistent, predictable earnings. In addition, through fundamental
            research, the portfolio manager seeks to identify dominant
            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 sells stocks in the Growth segment when the portfolio manager
            believes that earnings, sentiment and relative performance are
            disappointing or if an alternative investment is more attractive.
            The remainder of the Fund's portfolio (approximately 50% of its
            value) will be selected using a "Value" style. The portfolio
            manager of this Value segment 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 sells a stock in the Value segment when he
            believes that the company's business fundamentals are weakening or
            when the stock's valuation has become excessive.

             The Fund may invest up to 15% of its assets in foreign
            securities, usually in the form of 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.

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
            (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. 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. 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 "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 dominant
            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 sells stocks when the portfolio managers believe that
            earnings, sentiment and relative performance are disappointing or
            if an alternative investment is more attractive.

             The Fund may also invest 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, usually
            in the form of 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

                                         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 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 did not offer Institutional
            Class or Administrative Class shares during the periods shown.
            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. 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 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) fees (if any),
            administrative fees and other expenses paid by Institutional Class
            and Administrative 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.

                                        40

            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 $1 billion to $10 billion at the
            time of investment.

             The Fund usually invests in approximately 40 common stocks. In
            selecting stocks, the portfolio managers use two distinct
            investment disciplines. Approximately 50% of the value of the
            Fund's portfolio will be selected using a "Growth" style. The
            portfolio manager of this Growth segment seeks to identify
            companies with well-defined "wealth creating" characteristics,
            including superior earnings growth, high profitability and
            consistent, predictable earnings. In addition, through fundamental
            research, the portfolio manager seeks to identify dominant
            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 sells stocks in the Growth segment when the portfolio manager
            believes that earnings, sentiment and relative performance are
            disappointing or if an alternative investment is more attractive.
            The remainder of the Fund's portfolio (approximately 50% of its
            value) will be selected using a "Value" style. The portfolio
            manager of this Value segment 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 sells a stock in the Value segment when he
            believes that the company's business fundamentals are weakening or
            when the stock's valuation has become excessive.

             The Fund may invest up to 15% of its assets in foreign
            securities, usually in the form of 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

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 date 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 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. Past performance is no
            guarantee of future results.

            companies with market capitalizations of between $100 million and

             The portfolio manager selects stocks for the Fund using a

             The Fund may also invest 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, usually
            in the form of American Depository Receipts (ADRs).

             In response to unfavorable market and other conditions, the Fund

            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 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 did not offer Institutional
            Class or Administrative Class shares during the periods shown.
            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. 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 Class C performance
            has been adjusted to reflect that there are no sales charges and
            lower distribution and/or service (12b-1 fees) 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.

            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

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in common stocks of companies
            which utilize 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. 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 dominant 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 sells stocks when the portfolio
            manager believes that earnings, sentiment and relative performance
            are disappointing or if an alternative investment is more
            attractive.

             The Fund may also invest 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, usually
            in the form of 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
              .Concentration Risk     .Foreign Investment Risk  .Management Risk
              .Growth Securities 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 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 did not offer Institutional
            Class or Administrative Class shares during the periods shown.
            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. 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 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) 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.

            shares of the Fund with the costs of investing in other mutual

            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

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in an international portfolio
            of common stocks. Although the Fund normally invests in securities
            traded principally in developed foreign securities 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.

             In making investment decisions for the Fund, the portfolio
            managers attempt to identify growth companies whose securities are
            trading at a reasonable price. They first rank the companies in
            the Fund's international investment universe according to a number
            of growth characteristics, including earnings growth, dividend
            growth, profit growth and the company's history of meeting
            earnings targets. The portfolio managers then screen this ranking
            in order to eliminate stocks that appear to be overvalued, based
            on factors such as price-to-earnings, price-to-book and price-to-
            cash flow ratios. They then construct a portfolio for the Fund
            that is reasonably diversified across countries, industries and
            market capitalizations. The portfolio managers sell a stock when
            the company's growth characteristics are deteriorating or when the
            stock's valuation becomes excessive. Stocks are also sold in order
            to rebalance the Fund's country, industry and/or market
            capitalization weightings.

             The Fund invests most of its assets in foreign securities which
            trade primarily in currencies other than the U.S. dollar. It may
            also invest directly in foreign currencies and invest up to 10% of
            its assets in other investment companies.

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

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

             .Foreign Investment   .Growth Securities Risk   .Concentration Risk
              Risk                  Risk
             .Currency Risk        .Value Securities Risk    .Credit Risk
             .Market Risk          .Smaller Company Risk     .Management Risk
             .Issuer Risk          .Liquidity Risk

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

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

            (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 0.30% 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, 2000.


            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
            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.

            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
            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 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

             The portfolio management team rescreens the universe frequently

            in the Fund's capitalization range or to companies in the same

            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 smaller 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 $100 million, but excluding the 1,000
            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.

            The information provides some indication of the risks of investing

            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
            (9/27/95), 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. 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 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 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 3% 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.

                                    40-50

            The Fund seeks to achieve its investment objective by normally
            investing at least 65% of its assets in income-producing (or
            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.

            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 (or 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
            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

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 chart and 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 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 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 (or 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 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 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 Fund's investment objective and principal
            strategies.

          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 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.

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
            (11/1/95), 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. Past performance is no guarantee

                    common stocks that are publicly
                    traded in the U.S.
</TABLE>

            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. 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.

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>

            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 superior 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 sells 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.

</TABLE>

             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 business relates to, 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.

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

</TABLE>

             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 business relates to, 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.

              The Fund intends to invest substantially all of its assets in
             common stocks and other equity and equity-linked securities (aside
             from certain cash management practices) 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.

              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.

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
            (9/30/98), 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. The Fund had different sub-
            advisers during the periods prior to November 15, 1994, 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.

            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       Each Fund may invest in companies that may not be expected to
Securities  experience significant earnings growth, but whose securities its
Risk        portfolio manager believes are selling at a price lower than their
            true value. The Renaissance, Core Equity, Mid-Cap Equity, Mega-
            Cap, Capital Appreciation, Mid-Cap Growth, Small-Cap Growth,
            Micro-Cap Growth, Equity Income, Value, Value 25 and Small-Cap
            Value 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.

Growth      Each Fund may invest in equity securities of companies that its
Securities  portfolio manager believes will experience relatively rapid
Risk        earnings growth. The Growth, Core Equity, Target, Mid-Cap Equity,
            Opportunity, Innovation, International Growth, Mega-Cap, Capital
            Appreciation, Mid-Cap Growth, Small-Cap Growth and Micro-Cap
            Growth 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.

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 Micro-Cap Growth Fund, in
            particular, and the Opportunity, Small-Cap Growth and Small-Cap
            Value Funds generally have substantial exposure to this risk. The
            Target, Mid-Cap Equity, Mid-Cap Growth and Value 25 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.

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        Growth, Small-Cap Growth, Micro-Cap Growth, Equity Income, Value,
            Value 25 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.

Foreign     A Fund that invests in foreign securities, and particularly the
(non-       International Growth, Structured Emerging Markets, Tax-Efficient
U.S.)       Structured Emerging Markets and 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 International Growth,
            Structured Emerging Markets, Tax-Efficient Structured Emerging
            Markets or International Funds, invests a significant portion of
            its assets in a concentrated geographic area like 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 a Fund's investment in foreign
            securities.
                                                                   Prospectus 50
<PAGE>

Emerging       Foreign investment risk may be particularly high to the extent
Markets        that a Fund invests in emerging market securities of issuers
Risk           based inn 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
               International Fund may also invest a significant portion of its
               assets in emerging market securities.

Currency       Funds that invest directly in foreign currencies or in securities
Risk           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 International Growth, 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.

Concentration  Concentration of investments in a small number of issuers,
Risk           industries or foreign currencies increases risk. Funds such as
               the Value 25 Fund that invest in a relatively small number of
               issuers are more susceptible to risks associated with a single
               economic, political or regulatory occurrence than a more
               diversified Fund might be. Some of those issuers also may present
               substantial credit or other risks. The International Growth,
               Structured Emerging Markets, Tax-Efficient Structured Emerging
               Markets and International Funds may be subject to this risk to
               the extent that they concentrate their assets in securities
               denominated in a particular foreign currency or in a concentrated
               geographic area outside the U.S. Similarly, the 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 concentrates its investments in those
               companies.


Leveraging     Certain Funds may engage in transactions or purchase instruments
Risk           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. 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
               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. As interest
               rates rise, the value of fixed income securities in a Fund's
               portfolio are likely to decrease.

Credit         All of the Funds are subject to credit risk. This is the risk
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     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.





51 PIMCO Funds: Multi-Manager Series
<PAGE>

            Management of the Funds

Investment     PIMCO Advisors serves as the investment adviser and the
Adviser        administrator (serving in its capacity as administrator, the
and            "Administrator") for the Funds. Subject to the supervision of the
Administrator  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, 1999, PIMCO Advisors and its
               subsidiary partnerships had more than $256 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 Renaissance, Growth, Core Equity, Target, Mid-
               Cap Equity, Opportunity, Innovation and International Growth
               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, 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, 1999, 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):

               Funds were not operational during the entire fiscal year ended
               June 30, 1999. The annual investment advisory fee rates payable
               by these Funds are as follows (stated as a percentage of the
               average daily net assets of each Fund taken separately): Value

Administrative Each Fund pays for the administrative services it requires
Fees           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 various third-
               party services required by the Funds, including

                                                                   Prospectus 52

            audit, custodial, portfolio accounting, legal, transfer agency and
            printing costs. The result of this fee structure is an expense
            level for Institutional and Administrative Class shareholders of
            each Fund that, with limited exceptions, is precise and
            predictable under ordinary circumstances.

             For the fiscal year ended June 30, 1999, Institutional and
            Administrative Class shareholders of the Funds paid PIMCO Advisors
            monthly administrative fees at the following annual rates (stated

            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 except for the Capital Appreciation and Small-Cap Growth
            Funds. 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.

                                                                   Prospectus 58
<PAGE>

            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. The minimum initial investment may
            be waived for Institutional or Administrative Class shares offered
            to clients of PIMCO Equity Advisors, Cadence, NFJ, Pacific
            Investment Management, 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.

              . 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, 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.

              . Investment Limitations. Shares of the Micro-Cap Growth Fund
            are normally not available for purchase by new investors, although
            purchase orders may be accepted in certain circumstances. Existing
            shareholders may continue to invest in this Fund. This restriction
            may be changed or eliminated at any time at the discretion of the
            Trust's Board of Trustees.

                                                                   Prospectus 60
<PAGE>

              . 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.

61 PIMCO Funds: Multi-Manager Series
<PAGE>

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, 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.

                                                                   Prospectus 62
<PAGE>

             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.

             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.

Exchange    An investor may exchange Institutional Class or Administrative
Privilege   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. 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.

             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

63 PIMCO Funds: Multi-Manager Series
<PAGE>

            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 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 International Growth, 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.

             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.

                                                                   Prospectus 64
<PAGE>

            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, generally based upon recommendations provided by PIMCO
            Advisors and/or the relevant Sub-Adviser. 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 by
            calling the Trust at 1-800-927-4648.

             Shareholders do not pay any sales charges or other fees
            (including Fund Reimbursement Fees) on 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., on
            investments owned for more than 12 months). 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 International Growth,
            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

                                                                   Prospectus 66
<PAGE>

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

                      Aside from the cash management practices described below,
                    the International Growth, Mega-Cap, Capital Appreciation,
                    Mid-Cap Growth, Small-Cap Growth, Micro-Cap Growth, 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 Equity Income, Value,
                    Value 25 and Small-Cap Value Funds intend to be fully
                    invested in common stocks (aside from cash management
                    practices), except that each of these 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. The Renaissance, Growth, Core Equity,
                    Target, Mid-Cap Equity, Opportunity, Innovation 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
                    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      Each of the Funds may invest in securities of companies with
Smaller Market      market capitalizations that are small compared to other
Capitalizations     publicly traded companies. The Micro-Cap Growth Fund, in
                    particular, and the Opportunity, Small-Cap Growth and Small-
                    Cap Value Funds generally invest primarily in smaller
                    companies and are especially sensitive to the risks
                    described below. The Target, Mid-Cap Growth, Mid-Cap Equity
                    and Value 25 Funds also have significant exposure to these
                    risks because they invest primarily in companies with
                    medium-sized market capitalizations, which are smaller than
                    the largest companies.

67 PIMCO Funds: Multi-Manager Series
<PAGE>

             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     The International Growth, Structured Emerging Markets, Tax-
Securities  Efficient Structured Emerging Markets and International 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 Renaissance, Growth, Core
            Equity, Target, Mid-Cap Equity, Opportunity and Innovation Funds
            may invest up to 15% of their respective assets in foreign
            securities. The Enhanced 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 Renaissance, Growth, Core Equity,
            Target, Mid-Cap Equity, Opportunity, Innovation, International
            Growth, 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

                                                                   Prospectus 68
<PAGE>

            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
            Structured Emerging Markets and Tax-Efficient Structured Emerging
            Markets Funds normally invest most of their assets in emerging
            market securities. The International Fund may also invest a
            significant portion of its 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. Each of the Structured Emerging Markets, Tax-Efficient
            Structured Emerging Markets and International 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     A Fund that invests directly in foreign currencies or in
Currencies  securities that trade in, and receive revenues in, foreign
            currencies will be subject to currency risk. The International
            Growth, 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, significant
            uncertainty surrounds the recent introduction of the euro (a

            the effect it may have on the value of securities denominated in
            local European currencies. These and other currencies in which the

            International Growth, Structured Emerging Markets, Tax-Efficient
            Structured Emerging Markets and International Funds may enter into
            forward foreign currency exchange contracts to reduce the risks of
            adverse changes in foreign exchange rates. In addition, the
            International Growth, 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, 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 International Growth, 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 International
            Growth, Structured Emerging Markets, Tax-Efficient Structured
            Emerging Markets and International 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. The 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.

Convertible Each Fund may invest in convertible securities. Convertible
Securities  securities are generally preferred stocks and other securities,
            including fixed income securities and warrants, that are
            convertible into or exercisable for common stock at 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.

                                                                   Prospectus 70
<PAGE>

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.

Derivatives Each Fund (except the Mega-Cap, Capital Appreciation, Mid-Cap
            Growth, Small-Cap Growth, Micro-Cap Growth, Equity Income, Value,
            Value 25 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.

             Examples of derivative instruments include options contracts,
            futures contracts, options on futures contracts and swap
            agreements. The Renaissance, Growth, Core Equity, Target, Mid-Cap
            Equity, Opportunity, Innovation, International Growth, 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 International
            Growth, 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-     Each of the Structured Emerging Markets and Tax-Efficient
Linked      Structured Emerging Markets Funds may invest up to 15% of its net
Securities  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.

                                                                   Prospectus 72
<PAGE>

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 the value. Therefore, these
            transactions may result in a form of leverage and increase a
            Fund's overall investment exposure. Typically, no income accrues
            on securities a Fund has committed to purchase prior to the time
            delivery of the securities is made, although a Fund may earn
            income on securities it has segregated to cover these positions.

Repurchase  Each Fund may enter into repurchase agreements, in which the Fund
Agreements  purchases a security from a bank or broker-dealer 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.

Portfolio   With the exception of the Tax-Efficient Equity and Tax-Efficient
Turnover    Structured Emerging Markets Funds, the length of time a Fund has
            held a particular security is not generally a consideration in
            investment decisions.

73 PIMCO Funds: Multi-Manager Series
<PAGE>

            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.

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  The International Growth and International Funds may invest up to
in Other    10% of their assets in securities of other investment companies,
Investment  such as closed-end management investment companies, or in pooled
Companies   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.

Year 2000   Many of the services provided to the Funds depend on the smooth
Readiness   functioning of computer systems. Many systems in use today cannot
Disclosure  distinguish between the year 1900 and the year 2000. Should any of
            the service systems fail to process information properly, this
            could have an adverse impact on the Funds' operations and services
            provided to shareholders. PIMCO Advisors and its subsidiaries have
            surveyed the Funds' material service providers and believe that,
            on the basis of the information supplied, the service providers
            used by the Funds on January 1, 2000 will not be materially
            adversely affected by the so-called "year 2000 problem." However,
            there can be no assurance that the problem will be corrected in
            all respects and that the Funds' operations and services provided
            to shareholders will not be adversely affected, nor can there be
            any assurance that the year 2000 problem will not have an adverse
            effect on the entities whose securities are held by the Funds or
            on domestic or global equity markets or economies, generally.
            Accordingly, PIMCO Advisors and the Sub-Advisers reserve the right
            to vary, during the fourth quarter of 1999 and/or the first
            quarter of 2000, the investments of any Fund to maintain
            sufficient liquidity to satisfy actual or anticipated redemption
            activity.

            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.

            The Mega-Cap Fund did not offer Institutional or Administrative
            Class shares during the periods shown.

            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 11.

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. 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.

<PAGE>

            Summary Information (continued)

Asset       PIMCO Advisors L.P. serves as the investment adviser to the
Allocation  Portfolios. PIMCO Advisors' Asset Allocation Committee determines
Strategies  how each Portfolio allocates and reallocates its assets among the
            Underlying Funds 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 selects representative Underlying Funds for
            each Portfolio 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 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.

Portfolio   The following Portfolio Summaries identify each Portfolio's
Descriptionsinvestment objective, principal investments and strategies,
and Fees    principal risks and fees and expenses. A more detailed "Summary of
            Principal Risks" describing principal risks of investing in the
            Portfolios begins after the Portfolio Summaries. Because the
            Portfolios have not been in operation for a full calendar year, no
            performance information (e.g., a bar chart or average annual total
            returns table) is included for the Portfolios. A fuller discussion
            of the Portfolios' investment strategies and related information
            is included under "Investment Objectives and Principal Investment
            Strategies" in this Prospectus.

            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   Allocation Risk The Portfolio's investment performance depends
Risks       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 will not produce the desired results, and 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 .Concentration 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.

             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   Allocation Risk The Portfolio's investment performance depends
Risks       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 will not produce the desired results, and 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 Risk
              .Issuer Risk          .High Yield Risk    .Currency Risk
              .Value Securities Risk.Mortgage Risk      .Concentration Risk
              .Growth Securities Risk
                                    .Liquidity Risk     .Leveraging Risk
              .Smaller Company Risk .Derivatives Risk   .Management Risk
              .Interest Rate Risk   .Foreign Investment 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.

            (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   Allocation Risk The Portfolio's investment performance depends
Risks       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 will not produce the desired results, and 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 Risk

              .Credit Risk       .Growth Securities Risk.Currency 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.

                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,

                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

            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. 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 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.

11 PIMCO Funds: Multi-Manager Series
<PAGE>

Value       Each Underlying Stock Fund may invest in companies that may not be
Securities  expected to experience significant earnings growth, but whose
Risk        securities the Fund's portfolio manager believes are selling at a
            price lower than their true value. PIMCO Equity Income,
            Renaissance, Value, Value 25, Small-Cap Value, Capital
            Appreciation, Mid-Cap Growth, Small-Cap Growth and Micro-Cap
            Growth 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.

Growth      Each Underlying Stock Fund may invest in equity securities of
Securities  companies that its portfolio manager believes will experience
Risk        relatively rapid earnings growth. PIMCO Growth, Target,
            Opportunity, Capital Appreciation, Mid-Cap Growth, Small-Cap
            Growth, Micro-Cap Growth, International Growth and Innovation
            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.

Smaller     The general risks associated with equity securities and liquidity
Company     risk are particularly pronounced for securities of companies with
Risk        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, Small-Cap Growth, Micro-Cap Growth and Small-Cap
            Value Funds generally have substantial exposure to this risk.
            PIMCO Target, Mid-Cap Growth and Value 25 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. 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.


                                                                   Prospectus 12

              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,
Investment  International Growth, Structured Emerging Markets, Tax-Efficient
Risk        Structured Emerging Markets, Global Bond, Foreign Bond and
            Emerging Markets Bond Funds) 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 concentrated geographic area like 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.


13 PIMCO Funds: Multi-Manager Series
<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    Many Underlying Funds may invest directly in foreign currencies or
Risk        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, International Growth, Structured Emerging Markets
            and Tax-Efficient Structured 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.
            For example, significant uncertainty surrounds the recent
            introduction of the euro (a common currency unit for the European
            Union) in January 1999 and its effect on the value of 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.

Concentration
Risk
            Concentration of investments in a small number of issuers,
            industries or foreign currencies increases risk. PIMCO Global
            Bond, Foreign Bond and Emerging Markets Bond Funds are "non-
            diversified," which means that they may invest a greater
            percentage of their assets in the securities of a single issuer
            than diversified mutual funds. Other Underlying Funds, such as
            PIMCO Value 25 Fund, 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 concentrate investments, the Underlying Funds are more
            susceptible to risks associated with a single economic, political
            or regulatory occurrence than a more diversified portfolio might
            be. Some of those investments also may present substantial credit
            or other risks. PIMCO International, International Growth,
            Structured Emerging Markets, Tax-Efficient Structured Emerging
            Markets, Global Bond, Foreign Bond and Emerging Markets Bond Funds
            may be subject to this risk to the extent they concentrate their
            assets in securities denominated in a particular foreign currency
            or in a concentrated geographic area outside the U.S. 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.

             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  Certain Underlying Funds may engage in transactions or purchase
Risk        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.
            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. 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.


                                                                   Prospectus 14
<PAGE>

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 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 volatility and higher levels of credit,
            liquidity and other risks than Funds that invest exclusively in
            higher quality fixed income securities (e.g., PIMCO Money Market
            and Long-Term U.S. Government Funds). High yield securities are
            considered predominately speculative with respect to the issuer's
            continuing ability to make principal and interest payments (credit
            risk). High yield 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 high yield securities and reduce an Underlying Bond
            Fund's ability to sell its high yield securities (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.

15 PIMCO Funds: Multi-Manager Series

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

                                                                   Prospectus 16

            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. PIMCO Advisors' Asset Allocation Committee determines
            how each Portfolio allocates and reallocates its assets among the
            Underlying Funds 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

              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.

            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
            whether the Portfolio remains an appropriate investment in light
            of their then current financial positions and needs.

            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.

Advisory    PIMCO Advisors serves as investment adviser for each of the

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

            In addition to the Funds listed above, a Portfolio may invest in
            additional Underlying Funds, including those that may become

            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.

Year 2000   Many of the services provided to the Portfolios and the Underlying
Readiness   Funds depend on the smooth functioning of computer systems. Many
Disclosure  systems in use today cannot distinguish between the year 1900 and
            the year 2000. Should any of the service systems fail to process
            information properly, this could have an adverse impact on the
            operations of the Portfolios and/or the Underlying Funds and
            services provided to shareholders. PIMCO Advisors, its
            subsidiaries and Pacific Investment Management Company have
            surveyed the Portfolios' and the Underlying Funds' material
            service providers and believe that, on the basis of the
            information supplied, the service providers used by the Portfolios
            and the Underlying Funds on January 1, 2000 will not be materially
            adversely affected by the so-called "year 2000 problem." However,
            there can be no assurance that the problem will be corrected in
            all respects and that the operations of the Portfolios and the
            Underlying Funds and services provided to shareholders will not be
            adversely affected, nor can there be any assurance that the year
            2000 problem will not have an adverse effect on the entities whose
            securities are held by the Underlying Funds or on domestic or
            global equity or fixed income markets or economies, generally.
            Accordingly, PIMCO Advisors, Pacific Investment Management Company
            and the sub-advisers to the Underlying Funds reserve the right to
            vary, during the fourth quarter of 1999 and/or the first quarter
            of 2000, the investments of any Portfolio or Underlying Fund to
            maintain sufficient liquidity to satisfy actual or anticipated
            redemption activity.

            Management Company, to provide various administrative and other
            services required by the Portfolios in its capacity as sub-

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 various third-party services required by the
            Portfolios, including audit, custodial, portfolio accounting,
            legal, transfer agency and printing costs.

              The Portfolios were not operational for the entire fiscal year
            ended June 30, 1999. 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 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.

                                                                   Prospectus 24

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, Stanford, 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.

                                                                   Prospectus 26

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

Initial     Unless you are eligible for a waiver, the public offering price
Sales       you pay when you buy Class A shares of the Portfolios is the net
Charges--   asset value ("NAV") of the shares plus an initial sales charge.
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):

             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 portfolio 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 guidelines
            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, generally based upon recommendations
            provided by the Fund's investment adviser and/or sub-adviser. 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

<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.

             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:

                                    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 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:

<TABLE>
<CAPTION>
                     Initial Investment                 Subsequent Investments

                     $2,500 per Portfolio                 $100 per Portfolio
</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
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. 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

                                                                   Prospectus 30
<PAGE>

            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. 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, First Data Investor
            Services Group, 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;

31 PIMCO Funds: Multi-Manager Series
<PAGE>

              (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, and
            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
            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 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.

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
In Kind
            The Trust has agreed 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 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.

                                                                   Prospectus 32

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 be revised in the future to permit it to
            reject signature guarantees from Eligible Guarantor Institutions
            that do not, based on credit guidelines, satisfy such written
            standards or procedures. 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.

            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.

             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.

             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.

            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 11.

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. 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' Asset Allocation Committee determines
Strategies  how each Portfolio allocates and reallocates its assets among the
            Underlying Funds 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 selects representative Underlying Funds for
            each Portfolio 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 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. 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 following Portfolio Summaries identify each Portfolio's

            Principal Risks" describing principal risks of investing in the
            Portfolios begins after the Portfolio Summaries. Because the
            Portfolios have not been in operation for a full calendar year, no
            performance information (e.g., a bar chart or average annual total
            returns table) is included for the Portfolios. A fuller discussion
            of the Portfolios' investment strategies and related information
            is included under "Investment Objectives and Principal Investment
            Strategies" in this Prospectus.

            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   Allocation Risk The Portfolio's investment performance depends
Risks       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 will not produce the desired results, and 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 Risk
                                                        .Credit Risk
              .Value Securities Risk.Emerging Markets Risk
                                                        .High Yield Risk
              .Growth Securities Risk
                                    .Currency Risk      .Mortgage Risk
              .Smaller Company Risk .Concentration 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.

                0.10%, and Total Annual Portfolio Operating Expenses are
                estimated to be as follows: Institutional Class - 0.86%;

            (2) Based on estimated expenses for the current fiscal year.
                Underlying Fund Expenses for the Portfolio are estimated based

                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

            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   Allocation Risk The Portfolio's investment performance depends
Risks       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 will not produce the desired results, and 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 Risk
              .Issuer Risk          .High Yield Risk    .Currency Risk

Principal   Allocation Risk The Portfolio's investment performance depends

                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

            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. 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 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.

11 PIMCO Funds: Multi-Manager Series
<PAGE>

Value       Each Underlying Stock Fund may invest in companies that may not be
Securities  expected to experience significant earnings growth, but whose
Risk        securities the Fund's portfolio manager believes are selling at a
            price lower than their true value. PIMCO Equity Income,
            Renaissance, Value, Value 25, Small-Cap Value, Capital
            Appreciation, Mid-Cap Growth, Small-Cap Growth and Micro-Cap
            Growth 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.

Growth      Each Underlying Stock Fund may invest in equity securities of
Securities  companies that its portfolio manager believes will experience
Risk        relatively rapid earnings growth. PIMCO Growth, Target,
            Opportunity, Capital Appreciation, Mid-Cap Growth, Small-Cap
            Growth, Micro-Cap Growth, International Growth and Innovation
            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.

Smaller     The general risks associated with equity securities and liquidity
Company     risk are particularly pronounced for securities of companies with
Risk        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, Small-Cap Growth, Micro-Cap Growth and Small-Cap
            Value Funds generally have substantial exposure to this risk.
            PIMCO Target, Mid-Cap Growth and Value 25 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. 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.


                                                                   Prospectus 12
<PAGE>

              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-       International Growth, Structured Emerging Markets, Tax-Efficient
U.S.)       Structured Emerging Markets, Global Bond, Foreign Bond and
Investment  Emerging Markets Bond Funds) invest in securities of foreign
Risk        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 concentrated geographic area like 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.


13 PIMCO Funds: Multi-Manager Series
<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    Many Underlying Funds may invest directly in foreign currencies or
Risk        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, International Growth, Structured Emerging Markets
            and Tax-Efficient Structured 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.
            For example, significant uncertainty surrounds the recent
            introduction of the euro (a common currency unit for the European
            Union) in January 1999 and its effect on the value of 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.

Concentration
Risk
            Concentration of investments in a small number of issuers,
            industries or foreign currencies increases risk. PIMCO Global
            Bond, Foreign Bond and Emerging Markets Bond Funds are "non-
            diversified," which means that they may invest a greater
            percentage of their assets in the securities of a single issuer
            than diversified mutual funds. Other Underlying Funds, such as
            PIMCO Value 25 Fund, 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 concentrate investments, the Underlying Funds are more
            susceptible to risks associated with a single economic, political
            or regulatory occurrence than a more diversified portfolio might
            be. Some of those investments also may present substantial credit
            or other risks. PIMCO International, International Growth,
            Structured Emerging Markets, Tax-Efficient Structured Emerging
            Markets, Global Bond, Foreign Bond and Emerging Markets Bond Funds
            may be subject to this risk to the extent they concentrate their
            assets in securities denominated in a particular foreign currency
            or in a concentrated geographic area outside the U.S. 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.

             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  Certain Underlying Funds may engage in transactions or purchase
Risk        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.
            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. 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.


                                                                   Prospectus 14
<PAGE>

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 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 volatility and higher levels of credit,
            liquidity and other risks than Funds that invest exclusively in
            higher quality fixed income securities (e.g., PIMCO Money Market
            and Long-Term U.S. Government Funds). High yield securities are
            considered predominately speculative with respect to the issuer's
            continuing ability to make principal and interest payments (credit
            risk). High yield 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 high yield securities and reduce an Underlying Bond
            Fund's ability to sell its high yield securities (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.

15 PIMCO Funds: Multi-Manager Series

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

                                                                   Prospectus 16

            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. PIMCO Advisors' Asset Allocation Committee determines
            how each Portfolio allocates and reallocates its assets among the
            Underlying Funds 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.

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.

                                                                   Prospectus 18
<PAGE>


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.

            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

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.

Disclosure  systems in use today cannot distinguish between the year 1900 and
            the year 2000. Should any of the service systems fail to process
            information properly, this could have an adverse impact on the
            operations of the Portfolios and/or the Underlying Funds and
            services provided to shareholders. PIMCO Advisors, its
            subsidiaries and Pacific Investment Management Company have
            surveyed the Portfolios' and the Underlying Funds' material
            service providers and believe that, on the basis of the
            information supplied, the service providers used by the Portfolios
            and the Underlying Funds on January 1, 2000 will not be materially
            adversely affected by the so-called "year 2000 problem." However,
            there can be no assurance that the problem will be corrected in
            all respects and that the operations of the Portfolios and the
            Underlying Funds and services provided to shareholders will not be
            adversely affected, nor can there be any assurance that the year
            2000 problem will not have an adverse effect on the entities whose
            securities are held by the Underlying Funds or on domestic or
            global equity or fixed income markets or economies, generally.
            Accordingly, PIMCO Advisors, Pacific Investment Management Company
            and the sub-advisers to the Underlying Funds reserve the right to
            vary, during the fourth quarter of 1999 and/or the first quarter
            of 2000, the investments of any Portfolio or Underlying Fund to
            maintain sufficient liquidity to satisfy actual or anticipated
            redemption activity.

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 various third-party services required by the Portfolios,
            including audit, custodial, portfolio accounting, legal, transfer
            agency and printing costs.

              The Portfolios were not operational for the entire fiscal year
            ended June 30, 1999. Each Portfolio is obligated to pay 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.

              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.

                                                                   Prospectus 24
<PAGE>

              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.

            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.


                                                                   Prospectus 26

            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. The minimum initial investment
            may be waived for Institutional or Administrative Class shares
            offered to clients of PIMCO Equity 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.

27 PIMCO Funds: Multi-Manager Series
<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, 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
            are not 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, 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 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

                                                                   Prospectus 28
<PAGE>

            (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.

              . 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.

29 PIMCO Funds: Multi-Manager Series
<PAGE>

Exchange    An investor may exchange Institutional Class or Administrative
Privilege   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. 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 portfolio 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 guidelines
            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

                                                                   Prospectus 30

            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, generally based upon recommendations
            provided by the Fund's investment adviser and/or sub-adviser. 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 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 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.

             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
