            PIMCO Funds: Multi-Manager Series
            Prospectus
            March 5, 1997
 
            PIMCO Funds: Multi-Manager Series (the "Trust") is an open-end se-
            ries management investment company offering sixteen separate di-
            versified investment portfolios (each a "Fund") in this Prospec-
            tus, each with different investment objectives and strategies. The
            address of PIMCO Funds: Multi-Manager Series is 840 Newport Center
            Drive, Suite 360, Newport Beach, CA 92660.
 
            Each Fund (except the Opportunity Fund) offers three classes of
            shares in this Prospectus: Class A shares (generally sold subject
            to an initial sales charge), Class B shares (sold subject to a
            contingent deferred sales charge) and Class C shares (sold subject
            to an asset based sales charge). The Opportunity Fund does not of-
            fer Class B shares. Through a separate prospectus, certain Funds
            offer up to two additional classes of shares, Institutional Class
            shares and Administrative Class shares. See "Alternative Purchase
            Arrangements."
 
            This Prospectus concisely describes the information investors
            should know before investing in Class A, Class B and Class C
            shares of the Funds. Please read this Prospectus carefully and
            keep it for further reference.
 
            Information about the investment objective of each Fund, along
            with a detailed description of the types of securities in which
            each Fund may invest, and of investment policies and restrictions
            applicable to each Fund, are set forth in this Prospectus. There
            can be no assurance that the investment objective of any Fund will
            be achieved. Because the market value of each Fund's investments
            will change, the investment returns and net asset value per share
            of each Fund will vary.

            amended or supplemented from time to time, is available free of

            The purpose of the foregoing tables is to assist investors in un-
            derstanding the various costs and expenses of the Trust that are
            borne directly or indirectly by Class A, Class B and Class C
            shareholders of the Funds. Class A, Class B and Class C shares of
            the Funds were not offered prior to the date of this Prospectus,
            although Class A, Class B (except for the Opportunity Fund) and
            Class C shares were previously offered by the predecessor of each
            of the Renaissance, Growth, Target, Opportunity, International,
            Innovation, Precious Metals and Tax Exempt Funds, each of which
            was a series of PIMCO Advisors Funds that reorganized as a Fund of
            the Trust on January 17, 1997. The information provided above for
            each of these Funds reflects the Fund's current fees and expenses
            and not the fees and expenses of its predecessor. The Examples for
            Class A shares assume payment of the current maximum applicable
            sales load. Due to the 12b-1 distribution fee imposed on Class B
            and Class C shares, a Class B or Class C shareholder of the Trust
            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 National Association of
            Securities Dealers, Inc.

            Financial Highlights
            The financial highlights set forth on the following pages present
            certain information and ratios as well as performance information
            for Funds whose predecessors offered Class A, Class B, or Class C
            shares prior to the date of this Prospectus as series of PIMCO Ad-
            visors Funds, each of which reorganized as a series of the Trust
            on January 17, 1997. The expense ratios provided in the financial
            highlights for these Funds reflect fee arrangements in effect for
            PIMCO Advisors Funds which differ from the fee arrangements appli-
            cable to the Funds of the Trust. The information provided below,
            which is included in the PIMCO Advisors Funds' Annual Report dated
            September 30, 1996, has been audited by the former independent ac-
            countants for the predecessors to such Funds for the periods list-
            ed, whose report thereon is also included in such Annual Report.
            The PIMCO Advisors Funds' Annual Report is incorporated by refer-
            ence in the Statement of Additional Information and may be ob-
            tained without charge from the Distributor. Financial Statements
            and related Notes are also incorporated by reference in the State-
            ment of Additional Information. The remaining Funds did not offer
            Class A, Class B or Class C shares prior to the date of this Pro-
            spectus.
               The following schedule of financial highlights for the Renais-
            sance Fund is for shares outstanding throughout the periods list-
            ed. The information provided reflects results of operations under
            the Fund's former investment objective and policies through Janu-
            ary 31, 1992; such results would not necessarily have been
            achieved had the Fund's current objective and policies then been
            in effect.

            the Fund's current objective and policies been in effect. On No-

 PIMCO Funds: Multi-Manager Series
<PAGE>
 
            Investment Objectives and Policies
            The investment objective and general investment policies of each
            Fund are described below. There can be no assurance that the in-
            vestment objective of any Fund will be achieved. Because the mar-
            ket value of each Fund's investments will change, the net asset
            value per share of each Fund will also vary.
 
 
FUND        EQUITY INCOME FUND seeks current income as a primary investment
DESCRIP-    objective, and long-term growth of capital as a secondary objec-
TIONS       tive. The Fund invests primarily in common stocks characterized by
            having below-average price to earnings ("P/E") ratios and higher
            dividend yields relative to their industry groups. In selecting
            securities, the Portfolio Manager classifies a universe of approx-
            imately 2,000 stocks by industry, each of which has a minimum mar-
            ket capitalization of $200 million at the time of investment. The
            universe is then screened to find the lowest P/E ratios in each
            industry, subject to application of quality and price momentum
            screens. From this group, approximately 25 stocks with the highest
            yields are chosen for the Fund. The universe is then rescreened to
            find the highest yielding stock in each industry, subject to ap-
            plication of quality and price momentum screens. From this group,
            approximately 25 stocks with the lowest P/E ratios are added to
            the Fund. Although quarterly rebalancing is a general rule, re-
            placements are made whenever an alternative stock within the same
            industry has a significantly lower P/E ratio or higher dividend
            yield than the current Fund holding. For information on other in-
            vestment policies, see "Investment Objectives and Policies--Equity
            Funds." See "Characteristics and Risks of Securities and Invest-
            ment Techniques" in this Prospectus and "Investment Objectives and
            Policies" in the Statement of Additional Information for more de-
            tails on investment practices and related risks. The Portfolio
            Manager for the Equity Income Fund is NFJ.
 
            RENAISSANCE FUND seeks long-term growth of capital and income. The
            Fund invests primarily in a variety of income-producing equity se-
            curities. Income-producing equity securities include common stocks
            that pay dividends, preferred stocks and securities (including
            debt securities) that are convertible into common stocks ("con-
            vertible securities").
               The Fund may invest a portion of its assets in preferred stocks
            and convertible securities rated at least B by Moody's Investors
            Service, Inc. ("Moody's") or Standard & Poor's Corporation ("S&P")
            (or similarly rated by another Nationally Recognized Statistical
            Rating Organization ("NRSRO"), or unrated but determined by the
            Portfolio Manager to be of comparable quality), and may invest up
            to 10% of its total assets in convertible securities rated below B
            by Moody's or S&P (or similarly rated by another NRSRO or unrated
            but determined by the Portfolio Manager to be of comparable quali-
            ty). Securities rated Ba or below by Moody's or BB or below by S&P
            (or of similar quality) are not considered to be of "investment
            grade" quality. These lesser rated debt securities may involve
            special risks. See "Characteristics and Risks of Securities and
            Investment Techniques--Risks of High Yield Securities ("Junk
            Bonds")." Although the Fund may invest in such securities, it nei-
            ther invests nor has the present intention of investing 35% or
            more of its net assets in securities that are not considered to be
            of "investment grade" quality. The Fund will not invest in con-
            vertible securities that are in default at the time of acquisi-
            tion.
               The non-convertible debt securities in which the Fund may in-
            vest include corporate or government debt securities of any matu-
            rity, including zero coupon securities. These non-convertible debt
            securities may be rated B or higher by Moody's or S&P (or simi-
            larly rated by another NRSRO or unrated and determined by the
            Portfolio Manager to be of comparable quality). The Fund may in-
            vest a portion of its assets in securities of foreign issuers
            traded in foreign securities markets (not including Eurodollar
            certificates of deposit), which will not exceed 15% of the Fund's
            assets at the time of investment. Investing in the securities of
            foreign issuers involves special risks and considerations not typ-
            ically associated with investing in U.S. companies. The Fund may
            also purchase and write call and put options on securities and se-
            curities indexes; enter into futures contracts and use options on
            futures contracts; buy or sell foreign currencies; and enter into
            forward foreign currency contracts. For information on other in-
            vestment policies, see "Investment Objectives and Policies--Equity
            Funds." See "Characteristics and Risks of Securities and Invest-
            ment Techniques" in this Prospectus and "Investment Objectives and
            Policies" in the Statement of Additional Information for more de-
            tails on investment practices and related risks. The Portfolio
            Manager for the Renaissance Fund is Columbus Circle.

            VALUE FUND seeks long-term growth of capital and income. The Fund
            invests primarily in common stocks characterized by having below-
            average P/E ratios relative to their industry group. In selecting
            securities, the Portfolio Manager classifies a universe of approx-
            imately 2,000 stocks by industry, each of which has a minimum mar-
            ket capitalization of $200 million at the time of investment. The
            universe is then screened to find the stocks with the lowest P/E
            ratios in each industry, subject to application of quality and
            price momentum screens. The stocks in each industry with the low-
            est P/E ratios that pass the quality and price momentum screens
            are then selected for the Fund. The Fund usually invests in ap-
            proximately 50 stocks. Although quarterly rebalancing is a general
            rule, replacements are made whenever an alternative stock within
            the same industry has a significantly lower P/E ratio than the
            current Fund holdings. For information on other investment poli-
            cies, see "Investment Objectives and Policies--Equity Funds." See
            "Characteristics and Risks of Securities and Investment Tech-
            niques" in this Prospectus and "Investment Objectives and Poli-
            cies" in the Statement of Additional Information for more details
            on investment practices and related risks. The Portfolio Manager
            for the Value Fund is NFJ.
 
            CAPITAL APPRECIATION FUND seeks growth of capital. The Fund in-
            vests primarily in common stocks of companies that have improving
            fundamentals (such as growth of earnings and dividends) and whose
            stock is reasonably valued by the market. Stocks for the Fund are
            selected from a universe of the approximately 1,000 largest market
            capitalization stocks, all of which are those of companies with
            market capitalizations of at least $100 million at the time of in-
            vestment. The Fund usually invests in approximately 60 to 100 com-
            mon stocks. Each issue is screened and ranked using five distinct
            computerized models, including: (i) a dividend growth screen, (ii)
            an equity growth screen, (iii) an earnings growth screen, (iv) an
            earnings momentum screen, and (v) an earnings surprise screen. The
            Portfolio Manager believes that the models identify the stocks in
            the universe exhibiting growth characteristics with reasonable
            valuations. Stocks are replaced when they score worse-than-median
            screen ranks, have negative earnings surprises, or show poor rela-
            tive price performance. The universe is rescreened frequently to
            obtain a favorable composition of growth and value characteristics
            for the entire Fund. For information on other investment policies,

            practices and related risks. The Portfolio Manager for the Capital
            Appreciation Fund is Cadence.
 
            GROWTH FUND seeks long-term growth of capital. Income is an inci-
            dental consideration. The Fund invests primarily in common stocks
            of companies with medium to large market capitalizations. The Fund
            may invest a portion of its assets in securities of foreign is-
            suers traded in foreign securities markets (not including Eurodol-
            lar certificates of deposit), which will not exceed 15% of the
            Fund's assets at the time of investment. Investing in the securi-
            ties of foreign issuers involves special risks and considerations
            not typically associated with investing in U.S. companies. The
            Fund may also purchase and write call and put options on securi-
            ties and securities indexes; enter into futures contracts and use
            options on futures contracts; buy or sell foreign currencies; and
            enter into forward foreign currency contracts. For information on
            other investment policies, see "Investment Objectives and Poli-
            cies--Equity Funds." See "Characteristics and Risks of Securities
            and Investment Techniques" in this Prospectus and "Investment Ob-
            jectives and Policies" in the Statement of Additional Information

            Portfolio Manager for the Growth Fund is Columbus Circle.
 
            MID CAP GROWTH FUND seeks growth of capital. The Fund invests pri-
            marily in common stocks of middle capitalization companies that
            have improving fundamentals (such as growth of earnings and divi-
            dends) and whose stock is reasonably valued by the market. Stocks
            for the Fund are selected from a universe of companies with market
            capitalizations in excess of $500 million at the time of invest-
            ment, excluding the 200 companies with the highest market capital-
            ization. The Fund usually invests in approximately 60 to 100 com-
            mon stocks. Each issue is screened and ranked using five distinct
            computerized models, including: (i) a dividend growth screen, (ii)
            an equity growth screen, (iii) an earnings

            growth screen, (iv) an earnings momentum screen, and (v) an earn-
            ings surprise screen. The Portfolio Manager believes that the mod-
            els identify the stocks in the universe exhibiting growth charac-
            teristics with reasonable valuations. Stocks are replaced when
            they score worse-than-median screen ranks, have negative earnings
            surprises, or show poor relative price performance. The universe
            is rescreened frequently to obtain a favorable composition of
            growth and value characteristics for the entire Fund. For informa-

            TARGET FUND seeks capital appreciation. No consideration is given
            to income. The Fund invests primarily in common stocks of compa-
            nies with medium market capitalizations. The Fund may invest a
            portion of its assets in securities of foreign issuers traded in
            foreign securities markets (not including Eurodollar certificates
            of deposit), which will not exceed 15% of the Fund's assets at the
            time of investment. Investing in the securities of foreign issuers
            involves special risks and considerations not typically associated
            with investing in U.S. companies. The Fund may also purchase and
            write call and put options on securities and securities indexes;
            enter into futures contracts and use options on futures contracts;
            buy or sell foreign currencies; and enter into forward foreign
            currency contracts. For information on other investment policies,
            see "Investment Objectives and Policies--Equity Funds." See "Char-
            acteristics and Risks of Securities and Investment Techniques" in
            this Prospectus and "Investment Objectives and Policies" in the
            Statement of Additional Information for more details on investment
            practices and related risks. The Portfolio Manager for the Target
            Fund is Columbus Circle.
 
            SMALL CAP VALUE FUND seeks long-term growth of capital and income.
            The Fund invests primarily in common stocks of companies with mar-
            ket capitalizations between $50 million and $1 billion at the time
            of investment. In selecting securities, the Portfolio Manager di-
            vides a universe of up to approximately 2,000 stocks into quar-
            tiles based upon P/E ratio. The lowest quartile in P/E ratio is
            screened for market capitalizations between $50 million and $1
            billion, subject to application of quality and price momentum
            screens. Approximately 100 stocks with the lowest P/E ratios are
            combined in the Fund, subject to limits on the weighting for any
            one industry. Although quarterly rebalancing is a general rule,
            replacements are made whenever a holding achieves a higher P/E ra-
            tio than the S&P 500's P/E ratio or its industry average P/E ra-
            tio, or when an alternative stock within the same industry has a
            significantly lower P/E ratio than the current Fund holding. The
            Fund is intended for aggressive investors seeking above-average
            gains and willing to accept the greater risks associated there-
            with. For information on other investment policies, see "Invest-
            ment Objectives and Policies--Equity Funds." See "Characteristics
            and Risks of Securities and Investment Techniques" in this Pro-
            spectus and "Investment Objectives and Policies" in the Statement

            and related risks. The Portfolio Manager for the Small Cap Value
            Fund is NFJ.
 
            OPPORTUNITY FUND seeks capital appreciation. No consideration is
            given to income. Except to the extent described under "How to Buy
            Shares--Limited Offering of Shares of the Opportunity Fund to New
            Investors," the Fund is closed to new investors. The Fund invests
            primarily in common stocks of companies with market capitaliza-
            tions of less than $1 billion. The Fund is intended for aggressive
            investors seeking above-average gains and willing to accept the
            greater risks associated therewith.
               The Fund may invest a portion of its assets in securities of
            foreign issuers traded in foreign securities markets (not includ-
            ing Eurodollar certificates of deposit), which will not exceed 15%
            of the Fund's assets at the time of investment. Investing in the
            securities of foreign issuers involves special risks and consider-
            ations not typically associated with investing in U.S. companies.
            The Fund may also purchase and write call and put options on secu-
            rities and securities indexes; enter into futures contracts and
            use options on futures contracts; buy or sell foreign currencies;
            and enter into forward foreign currency contracts. For information

             "Investment Objectives and Policies" in the Statement of Addi-

            INTERNATIONAL DEVELOPED FUND seeks long-term growth of capital.
            The Fund invests primarily in a diversified portfolio of interna-
            tional equity securities. The Morgan Stanley Capital International
            EAFE (Europe, Australasia, Far East) Index ("EAFE Index") is used
            as a basis for choosing the countries in which the Fund invests.
            However, the Fund is not limited to the countries and weightings
            of the EAFE Index. Under normal market conditions, the Fund will
            invest no more than 35% of its assets in securities issued by com-
            panies located in countries that the Portfolio Manager determines,
            on the basis of market capitalization, liquidity, and other con-
            siderations, to have underdeveloped securities markets. The Port-
            folio Manager applies two levels of screening in selecting invest-
            ments for the Fund. First, an active country selection model ana-
            lyzes world markets and assigns a relative value ranking, or
            "favorability weighting," to each country in the relevant country
            universe to determine markets which are relatively undervalued.
            Second, at the stock selection level, quality analysis and value
            analysis are applied to each security, assessing variables such as
            balance sheet strength and earnings growth (quality factors) and
            performance relative to the industry, price to earnings ratios and
            price to book ratios (value factors). This two-level screening
            method identifies undervalued securities for purchase and also
            provides a sell discipline for fully valued securities. In select-
            ing securities, the Portfolio Manager considers, to the extent
            practicable and on the basis of information available to it for
            research, a company's environmental business practices.
               For purposes of allocating the Fund's investments, a company is
            considered to be located in the country in which it is domiciled,
            in which it is primarily traded, from which it derives a signifi-
            cant portion of its revenues, or in which a significant portion of
            its goods or services are produced.
               Most of the international equity securities in which the Fund
            invests will be traded in foreign currencies. The Fund may engage
            in foreign currency transactions to protect itself against fluctu-
            ations in currency exchange rates in relation to the U.S. dollar
            or to the weighting of a particular foreign currency on the EAFE
            Index. Such foreign currency transactions may include forward for-
            eign currency contracts, foreign exchange futures contracts, and
            options thereon, currency exchange transactions on a spot (i.e.,
            cash) basis, and put and call options on foreign currencies. Up to
            10% of the Fund's assets may be invested in the securities of
            other investment companies. The Fund may invest in stock index
            futures contracts, and options thereon, and may sell (write) call
            and put options. The Fund also may engage in equity index swap
            transactions.
               Investing in the securities of foreign issuers involves special
            risks and considerations not typically associated with investing
            in U.S. companies. For information on other investment policies,
            see "Investment Objectives and Policies--Equity Funds." See "Char-
            acteristics and Risks of Securities and Investment Techniques" in
            this Prospectus and "Investment Objectives and Policies" in the
            Statement of Additional Information for more details on investment
            practices and related risks. The Portfolio Manager for the Inter-
            national Developed Fund is Blairlogie.
 
            INTERNATIONAL FUND seeks capital appreciation through investments
            in an international portfolio. Income is an incidental considera-
            tion. Under normal market conditions, at least 65% of the Fund's
            total assets will be invested in common stocks, which may or may
            not pay dividends, as well as convertible bonds, convertible pre-
            ferred stocks, warrants, rights or other equity securities, for a
            combination of capital appreciation and income. Convertible secu-
            rities may include securities convertible only by certain classes
            of investors (which may not include the Fund). The Fund may not
            invest in convertible securities which are of less than investment
            grade quality at the time of purchase.
               The Fund will normally invest in securities traded in developed
            foreign securities markets. Particular consideration is given to
            investments principally traded in developed North American (other
            than United States), Japanese, European, Pacific and Australian
            securities markets, and in securities of foreign issuers traded on
            U.S. securities markets. The Fund will also invest in emerging
            markets, where markets may not yet fully reflect the potential of
            the developing economy. There are no prescribed limits on geo-
            graphic asset distribution and the Fund has the authority to

            invest in securities traded in securities markets of any country
            in the world. In allocating the Fund's assets among the various
            securities markets of any country of the world, the Portfolio Man-
            ager will consider such factors as the condition and growth poten-
            tial of the various economies and securities markets, currency and
            taxation considerations and other pertinent financial, social, na-
            tional and political factors. Under certain adverse investment
            conditions, the Fund may restrict the number of securities markets
            in which its assets will be invested, although under normal market
            circumstances the Fund's investments will include securities prin-
            cipally traded in at least three different countries. The Fund
            will not limit its investments to any particular type or size of
            company.
               The Fund may invest up to 10% of its assets in securities of
            other investment companies, such as closed-end management invest-
            ment companies which invest in foreign markets. The Fund may also
            purchase and write call and put options on securities, securities
            indexes, and on foreign currencies; enter into futures contracts
            and use options on futures contracts, including futures contracts
            on stock indexes and on foreign currencies; buy or sell foreign
            currencies; and enter into forward foreign currency contracts.
               The Fund will not normally invest in securities of U.S. issuers
            traded on U.S. securities markets. However, when the Portfolio
            Manager believes that conditions in international securities mar-
            kets warrant a defensive investment strategy, the Fund may invest
            up to 100% of its assets in domestic debt, foreign debt and equity
            securities principally traded in the U.S., including money market
            instruments, obligations issued or guaranteed by the U.S. or a
            foreign government or their respective agencies, authorities or
            instrumentalities, or corporate bonds and sponsored American De-
            pository Receipts.
               Investing in the securities of foreign issuers involves special
            risks and considerations not typically associated with investing
            in U.S. companies. For information on other investment policies,
            see "Investment Objectives and Policies--Equity Funds." See "Char-
            acteristics and Risks of Securities and Investment Techniques" in
            this Prospectus and "Investment Objectives and Policies" in the
            Statement of Additional Information for more details on investment
            practices and related risks. The Portfolio Manager for the Inter-
            national Fund is Blairlogie.
 
            EMERGING MARKETS FUND seeks long-term growth of capital. The Fund
            invests primarily in common stocks of companies located in coun-
            tries identified as emerging market countries. The Morgan Stanley
            Capital International Emerging Markets Free Index ("MSCI Free In-
            dex") and the International Finance Corporation Emerging Markets
            Index ("IFC Index") are used as the bases for choosing the coun-
            tries in which the Fund invests. However, the Fund is not limited
            to the countries and weightings of these indexes. The Portfolio
            Manager applies two levels of screening in selecting investments
            for the Fund. First, an active country selection model analyzes
            world markets and assigns a relative value ranking, or
            "favorability weighting," to each country in the relevant country
            universe to determine markets which are relatively undervalued.
            Second, at the stock selection level, quality analysis and value
            analysis are applied to each security, assessing variables such as
            balance sheet strength and earnings growth (quality factors) and
            performance relative to the industry, price to earnings ratios,
            and price to book ratios (value factors). This two-level screening
            method identifies undervalued securities for purchase as well as
            provides a sell discipline for fully valued securities. In select-
            ing securities, the Portfolio Manager considers, to the extent
            practicable and on the basis of information available to it for
            research, a company's environmental business practices.
               For purposes of implementing its investment objective, the Fund
            invests primarily in some or all of the following emerging market
            countries (this list is not exclusive):
 
              Argentina      Greece     Jordan      Poland       Thailand

               For purposes of allocating the Fund's investments, a company is
            considered to be located in the country in which it is domiciled,
            in which it is primarily traded, from which it derives a signifi-

            its goods or services are produced.
               Most of the foreign securities in which the Fund invests will
            be denominated in foreign currencies. The Fund may engage in for-
            eign currency transactions to protect itself against fluctuations
            in currency exchange rates in relation to the U.S. dollar or to
            the weighting of a particular foreign currency on the MSCI Free
            Index or the IFC Index. Such foreign currency transactions may in-
            clude forward foreign currency contracts, foreign exchange futures
            contracts, and options thereon, currency exchange transactions on
            a spot (i.e., cash) basis, and put and call options on foreign
            currencies. Up to 10% of the Fund's assets may be invested in the
            securities of other investment companies. The Fund may invest in
            stock index futures contracts, and options thereon, and may sell
            (write) call and put options. The Fund may also engage in equity
            index swap transactions.

            INNOVATION FUND seeks capital appreciation. No consideration is
            given to income. The Fund invests primarily (i.e., 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 tech-
            nologies. Securities will be selected with minimal emphasis on
            more traditional factors such as growth potential or value rela-
            tive to intrinsic worth. Instead, the Fund will be guided by the
            theory of Positive Momentum & Positive Surprise (see "Management
            of the Trust--Portfolio Managers--Columbus Circle"), with special
            emphasis on common stocks of companies whose perceived strength
            lies in their use of innovative technologies in new products, en-
            hanced distribution systems and improved management techniques.
            Although the Fund emphasizes the utilization of technologies, it
            is not restricted to investment in companies in a particular busi-
            ness sector or industry.
               The Fund may invest a portion of its assets in securities of
            foreign issuers traded in foreign securities markets (not includ-
            ing Eurodollar certificates of deposit), which will not exceed 15%
            of the Fund's assets at the time of investment. Investing in the
            securities of foreign issuers involves special risks and consider-
            ations not typically associated with investing in U.S. companies.
            The Fund may also purchase and write call and put options on secu-
            rities and securities indexes; enter into futures contracts and
            use options on futures contracts; buy or sell foreign currencies;
            and enter into forward foreign currency contracts. For information
            on other investment policies, see "Investment Objectives and Poli-
            cies--Equity Funds." See "Characteristics and Risks of Securities
            and Investment Techniques" in this Prospectus and "Investment Ob-
            jectives and Policies" in the Statement of Additional Information
            for more details on investment practices and related risks. The
            Portfolio Manager for the Innovation Fund is Columbus Circle.
 
            PRECIOUS METALS FUND seeks capital appreciation. No consideration
            is given to income. The Fund concentrates investments in a global
            portfolio of common stocks of companies principally engaged in
            precious metals-related activities, which include companies prin-
            cipally engaged in the extraction, processing, distribution or
            marketing of precious metals (the "precious metals industry"). A
            particular company is deemed to be "principally engaged" in the
            precious metals industry if at the time of investment the Portfo-
            lio Manager considers that at least 50% of the company's assets,
            revenues or profits are derived from the precious metals industry.
            Normally, at least 65% of the assets of the Fund will be invested
            in the precious metals industry and in securities the value of
            which is linked to the price of a precious metal. See "Character-
            istics and Risks of Securities and Investment Techniques--Precious
            Metals."

               The Fund will seek to identify securities of companies which,
            based upon the Portfolio Manager's evaluation of their fundamental
            investment characteristics, are undervalued in comparison to the
            present or anticipated value of the precious metals relevant to
            them. Examples of precious metals include gold, silver and plati-
            num. To the extent permitted by federal tax law, the Fund may in-
            vest directly in gold bullion and other precious metals. The Fund
            has no present intention of investing directly in precious metals
            other than gold.
               The Fund does not presently intend to invest more than 10% of
            its assets in either precious metals such as gold bullion or in
            futures on precious metals, such as gold futures, and options
            thereon. The Fund may invest up to 100% of its assets in securi-
            ties principally traded on foreign securities markets and in secu-
            rities of foreign issuers that are traded on U.S. securities mar-
            kets, and may invest up to 100% of its assets in securities of
            companies whose assets, revenues or profits are derived from a
            single precious metal. At the present time, the Fund has no inten-
            tion of investing more than 5% of its assets in securities the
            value of which is linked to the price of a single precious metal.
               The Fund may invest without limit in securities of foreign is-
            suers traded in foreign securities markets. Investing in the secu-
            rities of foreign issuers involves special risks and considera-
            tions not typically associated with investing in U.S. companies.
            The Fund may also purchase and write call and put options on secu-
            rities, securities indexes, commodity indexes, and on foreign cur-
            rencies; enter into futures contracts and use options on futures
            contracts, including futures contracts on stock indexes, foreign
            currencies, and precious metals; buy or sell foreign currencies;
            and enter into forward foreign currency contracts.
               The Fund, because of its emphasis on one industrial sector,
            should be considered as one aspect of a diversified portfolio and
            may not be suitable by itself as a balanced investment program.
            For information on other investment policies, see "Investment Ob-
            jectives and Policies--Equity Funds." See "Characteristics and
            Risks of Securities and Investment Techniques" in this Prospectus
            and "Investment Objectives and Policies" in the Statement of Addi-
            tional Information for more details on investment practices and
            related risks. The Portfolio Manager for the Precious Metals Fund
            is Van Eck.
 
            BALANCED FUND seeks total return consistent with prudent invest-
            ment management. The Fund attempts to achieve this objective
            through a management policy of investing in the following asset
            classes: common stock, fixed income securities, and money market
            instruments. The proportion of the Fund's total assets allocated
            among common stocks, fixed income securities, and money market in-
            struments will vary from time to time and will be determined by
            the Advisor. In determining the allocation of the Fund's assets
            among the three asset classes, the Advisor will employ asset allo-
            cation principles which take into account certain economic fac-
            tors, market conditions, and the expected relative total return
            and risk of the various asset classes. Under normal circumstances,
            it is anticipated that the Fund will generally maintain a balance
            among the types of securities in which it invests. Thus, the Fund
            will normally maintain 40% to 65% of its assets in common stock,
            at least 25% of its assets in fixed income securities, and less
            than 10% of its assets in money market instruments. However, in no
            event would the Fund invest in any common stock if, at the time of
            investment, more than 80% of the Fund's assets would be invested
            in common stock; in no event would the Fund invest in a fixed in-
            come security (other than a short-term instrument) if, at the time
            of investment, more than 80% of the Fund's assets would be in-
            vested in fixed income securities; nor would the Fund invest in a
            money market instrument if, at the time of investment, more than
            60% of its assets would be invested in money market instruments.
               In managing the Fund, the Advisor uses a specialist approach
            and has engaged three of the Trust's Portfolio Managers to manage
            certain portions of the Fund's assets. The portion of the assets
            of the Fund allocated by the Advisor for investment in common
            stock (the "Common Stock Segment") will be further allocated by
            the Advisor for investment by NFJ and Cadence. The portion of the
            Common Stock Segment allocated to NFJ will be managed in accor-
            dance with the investment policies of the Value Fund; the portion
            allocated to Cadence will be managed in accordance with the in-
            vestment policies of the Capital Appreciation Fund. Allocations of
            the Common Stock Segment to NFJ and Cadence will vary from time to
            time as determined by the Advisor.

               The portion of the assets of the Fund allocated by the Advisor
            for investment in fixed income debt securities (the "Fixed Income
            Securities Segment") will be managed by Pacific Investment Manage-
            ment. The Fund may invest the Fixed Income Securities Segment in
            the following types of securities: securities issued or guaranteed
            by the U.S. Government, its agencies or instrumentalities; corpo-
            rate debt securities, including convertible securities and corpo-
            rate commercial paper; mortgage-related and other asset-backed se-
            curities; inflation-indexed bonds issued by both governments and
            corporations; structured notes and loan participations; bank cer-
            tificates of deposit, fixed time deposits and bankers' accept-
            ances; repurchase agreements and reverse repurchase agreements;
            obligations of foreign governments or their subdivisions, agencies
            and instrumentalities; and obligations of international agencies
            or supranational entities. Fixed income securities may have fixed,
            variable, or floating rates of interest.
               The Fund invests the Fixed Income Securities Segment in fixed
            income securities of varying maturities. Portfolio holdings will
            be concentrated in areas of the bond market (based on quality,
            sector, coupon or maturity) that Pacific Investment Management be-
            lieves to be relatively undervalued. Fixed income securities in
            which the Fund may invest will, at the time of investment, be
            rated Baa or better by Moody's, BBB or better by S&P or, if not
            rated by Moody's or S&P, will be of comparable quality as deter-
            mined by Pacific Investment Management, except that up to 10% of
            the Fixed Income Securities Segment may be invested in lower rated
            securities that are rated B or higher by Moody's or S&P or, if not
            rated by Moody's or S&P, determined by Pacific Investment Manage-
            ment to be of comparable quality. High yield fixed income securi-
            ties rated lower than Baa by Moody's or BBB by S&P, or of equiva-
            lent quality, are not considered to be investment grade, and are
            commonly referred to as "junk bonds." Securities rated below in-
            vestment grade and comparable unrated securities are subject to
            greater risks than higher quality fixed income securities. See
            "Characteristics and Risks of Securities and Investment Tech-
            niques--Risks of High Yield Securities ("Junk Bonds")." The Fund
            also may invest up to 20% of the Fixed Income Securities Segment
            in securities denominated in foreign currencies, and may invest
            beyond this limit in U.S. dollar-denominated securities of foreign
            issuers.
               Each Portfolio Manager generally invests a portion of its allo-
            cation in liquid securities to facilitate redemptions. In addi-
            tion, PIMCO Advisors reserves the right to allocate a portion of
            the Fund's assets (the "Money Market Segment") for investment in
            money market instruments and reserves the right to manage the in-
            vestment of such assets. Because of the Fund's flexible investment
            policy, portfolio turnover may be greater than for a fund that
            does not allocate assets among various types of securities. See
            "Characteristics and Risks of Securities and Investment Tech-
            niques--Portfolio Turnover."
               The Fund may engage in the purchase and writing of put and call
            options on debt securities and securities indexes and may also
            purchase or sell interest rate futures contracts, stock index
            futures contracts, and options thereon. The Fund also may enter
            into swap agreements with respect to foreign currencies, interest
            rates, and securities indexes. With respect to securities of the
            Fixed Income Securities Segment denominated in foreign currencies,
            the Fund may engage in foreign currency exchange transactions by
            means of buying or selling foreign currencies on a spot basis, en-
            tering into forward foreign currency contracts, and buying and
            selling foreign currency options, foreign currency futures, and
            options on foreign currency futures. Foreign currency exchange
            transactions may be entered into for the purpose of hedging
            against foreign currency exchange risk arising from the Fund's in-
            vestment or anticipated investment in securities denominated in
            foreign currencies and for purposes of increasing exposure to a
            particular foreign currency or to shift exposure to foreign cur-
            rency fluctuations from one country to another. See "Characteris-
            tics and Risks of Securities and Investment Techniques" in this
            Prospectus and "Investment Objectives and Policies" in the State-

            practices and related risks.
 
            TAX EXEMPT FUND seeks high current income exempt from federal in-
            come tax, consistent with preservation of capital, by investing in
            debt securities whose interest is, in the opinion of bond counsel
            for the issuer at the time of issuance, exempt from federal income
            tax ("Tax Exempt Bonds"). Tax Exempt Bonds generally are issued by
            states and local governments and their agencies, authorities and
            other instrumentalities. It is a policy of the Fund that, under
            normal market conditions, at least 80% of its net assets will be
            invested in Tax Exempt Bonds rated Baa or higher by Moody's or BBB
            or higher by S&P, or which are similarly rated by another NRSRO,
            or if unrated, determined by the Portfolio

            Manager to be of quality comparable to obligations so rated. Tax
            Exempt Bonds rated in the fourth highest rating category (e.g.,
            Baa by Moody's) may be considered to possess some speculative
            characteristics by certain NRSROs.
               The Fund may invest up to 20% of its net assets, under normal
            market conditions, in any combination of (1) Tax Exempt Bonds
            which are rated at least Ba by Moody's or BB by S&P (or similarly
            rated by another NRSRO or, if unrated, determined by the Portfolio
            Manager to be of comparable quality) and (2) U.S. Government secu-
            rities, money market instruments or "private activity" bonds. Se-
            curities rated below investment grade and comparable unrated secu-
            rities are subject to greater risks than higher quality fixed in-
            come securities. See "Characteristics and Risks of Securities and
            Investment Techniques--Risks of High Yield Securities ("Junk
            Bonds")." For temporary defensive purposes the Fund may invest all
            or a portion of its assets in U.S. Government securities and money
            market instruments. The Fund may purchase put or call options on
            U.S. Government securities, Tax Exempt Bonds and Tax Exempt Bond
            indexes, purchase and sell futures contracts on U.S. Government
            securities, Tax Exempt Bonds and Tax Exempt Bond indexes, and pur-
            chase put and call options on such futures contracts. The Fund may
            enter into repurchase agreements with banks and broker-dealers;
            make short sales of securities held in the Fund's portfolio or
            which the Fund has the right to acquire without the payment of
            further consideration; and purchase and sell securities on a when-
            issued or delayed delivery basis and enter into forward commit-
            ments to purchase securities. The Fund may also invest a portion
            or, for temporary defensive purposes, up to 100% of its assets in
            money market instruments.
               Dividends to Fund shareholders derived from money market in-
            struments and U.S. Government securities are taxable as ordinary
            income. The Fund may seek to reduce fluctuations in its net asset
            value by engaging in portfolio strategies involving options on se-
            curities, futures contracts, and options on futures contracts. Any
            gain derived by the Fund from the use of such instruments will be
            treated as a combination of short-term and long-term capital gain
            and, if not offset by realized capital losses incurred by the
            Fund, will be distributed to shareholders and will be taxable to
            shareholders as a combination of ordinary income and long-term
            capital gain. See "Characteristics and Risks of Securities and In-
            vestment Techniques" in this Prospectus and "Investment Objectives
            and Policies" in the Statement of Additional Information for more
            details on investment practices and related risks. The Portfolio
            Manager for the Tax Exempt Fund is Columbus Circle.
 
 
EQUITY      The Equity Income, Value, Capital Appreciation, Mid Cap Growth,
FUNDS       Small Cap Value, International Developed and Emerging Markets
            Funds will each invest primarily (normally at least 65% of its as-
            sets) in common stock. Each of these Funds may maintain a portion
            of its assets, which will usually not exceed 10%, in U.S. Govern-
            ment securities, high quality debt securities (whose maturity or
            remaining maturity will not exceed five years), money market obli-
            gations, and in cash to provide for payment of the Fund's expenses
            and to meet redemption requests. It is the policy of these Funds
            to be as fully invested in common stocks as practicable at all
            times. This policy precludes these Funds from investing in debt
            securities as a defensive investment posture (although these Funds
            may invest in such securities to provide for payment of expenses
            and to meet redemption requests). Accordingly, investors in these
            Funds bear the risk of general declines in stock prices and the
            risk that a Fund's exposure to such declines cannot be lessened by
            investment in debt securities. These Funds may also invest in con-
            vertible securities, preferred stocks, and warrants, subject to
            certain limitations.
               The Renaissance, Growth, Target, Opportunity, International,
            Innovation and Precious Metals Funds (together with the Funds
            listed in the preceding paragraph, the "Equity Funds") will each
            invest primarily (normally at least 65% of its assets) in equity
            securities (income-producing equity securities in the case of the
            Renaissance Fund), including common stocks, preferred stocks and
            securities (including debt securities and warrants) convertible
            into or exercisable for common stocks. Each of these Funds may in-
            vest a portion of its assets in debt securities and, for temporary
            defensive purposes, up to 100% of its assets in short-term U.S.
            Government securities and other money market instruments.
               One or more of the Equity Funds may temporarily not be invested
            primarily in equity securities immediately following the commence-
            ment of operations or after receipt of significant new monies. Any
            of the Equity Funds may

            temporarily not contain the number of securities in which the Fund
            normally invests if the Fund does not have sufficient assets to be
            fully invested, or pending the Portfolio Manager's ability to pru-
            dently invest new monies.
               The Equity Funds may also lend portfolio securities; enter into
            repurchase agreements and reverse repurchase agreements (subject
            to the Funds' investment limitations described below); purchase
            and sell securities on a when-issued or delayed delivery basis;
            and enter into forward commitments to purchase securities. Each of
            the Equity Funds may invest in American Depository Receipts
            ("ADRs"). The International Developed, International, Emerging
            Markets and Precious Metals Funds may invest in European Deposi-
            tory Receipts ("EDRs") and Global Depository Receipts ("GDRs").
            The Equity Funds that invest primarily in securities of foreign
            issuers may invest a portion of their assets in debt securities
            and money market obligations issued by U.S. and foreign issuers
            that are either U.S. dollar-denominated or denominated in foreign
            currency. For more information on these investment practices, see
            "Characteristics and Risks of Securities and Investment Tech-
            niques" in this Prospectus and "Investment Objectives and Poli-
            cies" in the Statement of Additional Information.
 
 
DURATION    Under normal circumstances, the average portfolio duration of the
            Fixed Income Securities Segment of the Balanced Fund will vary
            within a three- to six-year time frame, and the average portfolio
            duration of the Tax Exempt Fund will vary within a three- to ten-
            year time frame, based on the relevant Portfolio Manager's fore-
            cast for interest rates. Duration is a measure of the expected
            life of a fixed income security that was developed as a more pre-
            cise alternative to the concept of "term to maturity." Tradition-
            ally, a fixed income security's "term to maturity" has been used
            as proxy for the sensitivity of the security's price to changes in
            interest rates (which is the "interest rate risk" or "volatility"
            of the security). However, "term to maturity" measures only the
            time until a fixed income security provides its final payment,
            taking no account of the pattern of the security's payments prior
            to maturity. In contrast, duration incorporates a bond's yield,
            coupon interest payments, final maturity and call features into
            one measure of the average life of a fixed income security on a
            present value basis. Duration management is one of the fundamental
            tools used by the Portfolio Managers for the Fixed Income Securi-
            ties Segment of the Balanced Fund and the Tax Exempt Fund. For
            more information on investments in fixed income securities, see
            "Characteristics and Risks of Securities and Investment Tech-
            niques" in this Prospectus and "Investment Objectives and Poli-
            cies" in the Statement of Additional Information.
 
            Characteristics and Risks of
            Securities and Investment Techniques
 
            The different types of securities and investment techniques used
            by the individual Funds all have attendant risks of varying de-
            grees. For example, with respect to common stock, there can be no
            assurance of capital appreciation, and there is a risk of market
            decline. With respect to debt securities, including money market
            instruments, there is the risk that the issuer of a security may
            not be able to meet its obligation to make scheduled interest or
            principal payments. Because each Fund seeks a different investment
            objective and has different investment policies, each is subject
            to varying degrees of financial, market and credit risks. There-
            fore, investors should carefully consider the investment objec-
            tive, investment policies, and potential risks of any Fund or
            Funds before investing.
               The following describes potential risks associated with differ-
            ent types of investment techniques that may be used by the indi-
            vidual Funds. For more detailed information on these investment
            techniques, as well as information on the types of securities in
            which some or all of the Funds may invest, see the Statement of
            Additional Information.
 
INVESTMENTS Certain of the Funds may invest in common stock of companies with
IN COM-     market capitalizations that are small compared to other publicly
PANIES WITH traded companies. Generally, small market capitalization is con-
SMALL AND   sidered to be less than $1 billion and large market capitalization
MEDIUM      is considered to be more than $5 billion. Under normal market con-
MARKET      ditions, the Small Cap Value and Opportunity Funds will invest
CAPITALIZA- primarily in companies with market capitalizations of $1 billion
TIONS       or less. Investments in larger companies present certain advan-
            tages in that such companies generally have greater financial re-
            sources, more

            extensive research and development, manufacturing, marketing and
            service capabilities, and more stability and greater depth of man-
            agement and technical personnel. Investments in smaller, less sea-
            soned companies may present greater opportunities for growth but
            also may involve greater risks than customarily are associated
            with more established companies. The securities of smaller compa-
            nies may be subject to more abrupt or erratic market movements
            than larger, more established companies. These companies may have
            limited product lines, markets or financial resources, or they may
            be dependent upon a limited management group. Their securities may
            be traded only in the over-the-counter market or on a regional se-
            curities exchange. As a result, the disposition of securities to
            meet redemptions may require a Fund to sell these securities at a
            disadvantageous time, or at disadvantageous prices, or to make
            many small sales over a lengthy period of time.
               Many of the Funds may also invest in stocks of companies with
            medium market capitalizations. The Target Fund may invest primar-
            ily in such securities. Whether a U.S. issuer's market capitaliza-
            tion is medium is determined by reference to the capitalization
            for all issuers whose equity securities are listed on a United
            States national securities exchange or which are reported on
            NASDAQ. Issuers with market capitalizations within the range of
            capitalization of companies included in the S&P Mid Cap 400 Index
            may be regarded as being issuers with medium market capitaliza-
            tions. Such investments share some of the risk characteristics of
            investments in stocks of companies with small market capitaliza-
            tions described above, although such companies tend to have longer
            operating histories, broader product lines and greater financial
            resources and their stocks tend to be more liquid and less vola-
            tile than those of smaller capitalization issuers.
 
FOREIGN     The International Developed, International and Emerging Markets
INVEST-     Funds may invest directly in foreign equity securities; U.S. dol-
MENTS       lar- or foreign currency-denominated foreign corporate debt secu-
            rities; foreign preferred securities; certificates of deposit,
            fixed time deposits and bankers' acceptances issued by foreign
            banks; obligations of foreign governments or their subdivisions,
            agencies and instrumentalities, international agencies and supra-
            national entities; and securities represented by ADRs, EDRs, or
            GDRs. ADRs are dollar-denominated receipts issued generally by do-
            mestic banks and representing the deposit with the bank of a secu-
            rity 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 trade in public or private
            markets in other countries. The Precious Metals Fund may invest
            primarily in securities of foreign issuers, securities denominated
            in foreign currencies, securities principally traded on securities
            markets outside of the United States and in securities of foreign
            issuers that are traded on U.S. securities markets, including
            ADRs, EDRs, and GDRs. The remaining Equity Funds and the Balanced
            Fund may also invest in ADRs. The Balanced Fund may invest up to
            20% of its Fixed Income Securities Segment in securities denomi-
            nated in foreign currencies, and may invest beyond this limit in
            U.S. dollar-denominated securities of foreign issuers. The Renais-
            sance, Growth, Target, Opportunity and Innovation Funds may invest
            up to 15% of their respective assets in securities which are
            traded principally in securities markets outside the United States
            (Eurodollar certificates of deposit are excluded for purposes of
            these limitations), and may invest without limit in securities of
            foreign issuers that are traded in U.S. markets.
               Investing in the securities of issuers in any foreign country
            involves special risks and considerations not typically associated
            with investing in U.S. companies. Shareholders should consider
            carefully the substantial risks involved in investing in securi-
            ties issued by companies and governments of foreign nations. These
            risks include: differences in accounting, auditing and financial
            reporting standards; generally higher commission rates on foreign
            portfolio transactions; the possibility of nationalization, expro-
            priation or confiscatory taxation; adverse changes in investment
            or exchange control regulations (which may include suspension of
            the ability to transfer currency from a country); and political
            instability which could affect U.S. investments in foreign coun-
            tries. Additionally, foreign securities and dividends and interest
            payable on those securities may be subject to foreign taxes, in-
            cluding taxes withheld from payments on those securities. Foreign
            securities often trade with less frequency and volume than domes-
            tic securities and therefore may exhibit greater price volatility.
            Additional costs associated with an investment in foreign securi-
            ties may include

                                                                              25

            higher custodial fees than apply to domestic custodial arrange-
            ments and transaction costs of foreign currency conversions.
            Changes in foreign exchange rates also will affect the value of
            securities denominated or quoted in currencies other than the U.S.
            dollar.
               A Fund's investments in foreign currency denominated debt obli-
            gations and hedging activities will likely produce a difference
            between its book income and its taxable income. This difference
            may cause a portion of the Fund's income distributions to consti-
            tute returns of capital for tax purposes or require the Fund to
            make distributions exceeding book income to qualify as a regulated
            investment company for federal tax purposes.
               Certain of the Funds and, in particular, the Emerging Markets
            Fund, may invest in the securities of issuers based in countries
            with developing economies. Investing in developing (or "emerging
            market") countries involves certain risks not typically associated
            with investing in U.S. securities, and imposes risks greater than,
            or in addition to, risks of investing in foreign, developed coun-
            tries. A number of emerging market countries restrict, to varying
            degrees, foreign investment in stocks. Repatriation of investment
            income, capital, and the proceeds of sales by foreign investors
            may require governmental registration and/or approval in some
            emerging market countries. A number of the currencies of emerging
            market countries have experienced significant declines against the
            U.S. dollar in recent years, 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. Many of the emerging securities
            markets are relatively small, have low trading volumes, suffer pe-
            riods of relative illiquidity, and are characterized by signifi-
            cant price volatility. There is a risk in emerging market coun-
            tries that a future economic or political crisis could lead to
            price controls, forced mergers of companies, expropriation or con-
            fiscatory taxation, seizure, nationalization, or creation of gov-
            ernment monopolies, any of which may have a detrimental effect on
            a Fund's investment.
               Additional risks of investing in emerging market countries may
            include: currency exchange rate fluctuations; greater social, eco-
            nomic and political uncertainty and instability (including the
            risk of war); more substantial governmental involvement in the
            economy; less governmental supervision and regulation of the secu-
            rities markets and participants in those markets; unavailability
            of currency hedging techniques in certain emerging market coun-
            tries; the fact that companies in emerging market countries may be
            newly organized and may be smaller and less seasoned companies;
            the difference in, or lack of, auditing and financial reporting
            standards, which may result in unavailability of material informa-
            tion about issuers; the risk that it may be more difficult to ob-
            tain and/or enforce a judgment in a court outside the United
            States; and significantly smaller market capitalization of securi-
            ties markets.
 
 
FOREIGN     Foreign currency exchange rates may fluctuate significantly over
CURRENCY    short periods of time. They generally are determined by the forces
TRANSAC-    of supply and demand in the foreign exchange markets and the rela-
TIONS       tive merits of investments in different countries, actual or per-
            ceived changes in interest rates and other complex factors, as
            seen from an international perspective. 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 in the U.S. or
            abroad. Currencies in which the Funds' assets are denominated may
            be devalued against the U.S. dollar, resulting in a loss to the
            Funds.
               The Renaissance, Growth, Target, Opportunity, International De-
            veloped, International, Emerging Markets, Innovation, Precious
            Metals and Balanced Funds may enter into forward foreign currency
            exchange contracts to reduce the risks of adverse changes in for-
            eign exchange rates. In addition, the International Developed, In-
            ternational, Emerging Markets, Precious Metals and Balanced Funds
            may buy and sell foreign currency futures contracts and options on
            foreign currencies and foreign currency futures. All of the Funds
            that may buy or sell foreign currencies may enter into forward
            foreign currency exchange contracts to reduce the risks of adverse
            changes in foreign exchange rates. A forward foreign currency ex-
            change contract involves an obligation to purchase or sell a spe-
            cific currency at a future date, which may be any fixed number of
            days from the date of the contract agreed upon by the parties, at
            a price set at the time of the contract. By entering into a for-
            ward foreign currency exchange contract, the Fund "locks in" the
            exchange rate

            between the currency it will deliver and the currency it will re-
            ceive for the duration of the contract. As a result, a Fund re-
            duces its exposure to changes in the value of the currency it will
            deliver and increases its exposure to changes in the value of the
            currency it will exchange into. 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 for the purpose
            of hedging against foreign exchange risk arising from the Fund's
            investment or anticipated investment in securities denominated in
            foreign currencies. Such hedging transactions may not be success-
            ful and may eliminate any chance for a Fund to benefit from favor-
            able fluctuations in relevant foreign currencies. The Interna-
            tional Developed, International and Emerging Markets Funds may
            also enter into hedging contracts for purposes of increasing expo-
            sure to a foreign currency or to shift exposure to foreign cur-
            rency fluctuations from one currency to another. To the extent
            that they do so, the International Developed, International and
            Emerging Markets Funds will be subject to the additional risk that
            the relative value of currencies will be different than antici-
            pated by the particular Fund's Portfolio Manager. These Funds may
            use one currency (or a basket of currencies) to hedge against ad-
            verse changes in the value of another currency (or a basket of
            currencies) when exchange rates between the two currencies are
            positively correlated. Each Fund will segregate assets determined
            to be liquid by the Advisor or a Portfolio Manager in accordance
            with procedures established by the Board of Trustees in a segre-
            gated account to cover its obligations under forward foreign cur-
            rency exchange contracts entered into for non-hedging purposes.
 
 
MONEY       Each of the Funds may invest at least a portion of its assets in
MARKET      the following kinds of money market instruments:
INSTRUMENTS    (1) short-term U.S. Government securities;
               (2) certificates of deposit, bankers' acceptances and other
               bank obligations rated in the two highest rating categories by
               at least two NRSROs, or, if rated by only one NRSRO, in such
               agency's two highest grades, or, if unrated, determined to be
               of comparable quality by the Advisor or a Portfolio Manager.
               Bank obligations must be those of a bank that has deposits in
               excess of $2 billion or that is a member of the Federal Deposit
               Insurance Corporation. A Fund may invest in obligations of U.S.
               branches or subsidiaries of foreign banks ("Yankee dollar obli-
               gations") or foreign branches of U.S. banks ("Eurodollar obli-
               gations");
               (3) commercial paper rated in the two highest rating categories
               by at least two NRSROs, or, if rated by only one NRSRO, in such
               agency's two highest grades, or, if unrated, determined to be
               of comparable quality by the Advisor or a Portfolio Manager;
               (4) corporate obligations with a remaining maturity of 397 days
               or less whose issuers have outstanding short-term debt obliga-
               tions rated in the highest rating category by at least two
               NRSROs, or, if rated by only one NRSRO, in such agency's high-
               est grade, or, if unrated, determined to be of comparable qual-
               ity by the Advisor or a Portfolio Manager; and
               (5) repurchase agreements with domestic commercial banks or
               registered broker-dealers.
 
 
MORTGAGE-   All Funds that may purchase debt securities for investment pur-
RELATEDAND  poses (and in particular, the Balanced Fund) may invest in mort-
OTHERASSET- gage-related securities, and in other asset-backed securities (un-
BACKED      related to mortgage loans) that are offered to investors in the
SECURITIES  future. The value of some mortgage-related or asset-backed securi-
            ties in which the Funds invest may be particularly sensitive to
            changes in prevailing interest rates, and, like the other fixed
            income investments, the ability of a Fund to successfully utilize
            these instruments may depend in part upon the ability of the Port-
            folio Manager to forecast interest rates and other economic fac-
            tors correctly.
 
            MORTGAGE PASS-THROUGH SECURITIES are securities representing in-
            terests in "pools" of mortgage loans secured by residential or
            commercial real property in which payments of both interest and
            principal on the securities are generally made monthly, in effect
            "passing through" monthly payments made by the individual borrow-
            ers on the mortgage loans which underlie the securities (net of
            fees paid to the issuer or guarantor of the securities). Early re-
            payment of principal on some mortgage-related securities (arising
            from prepayments of principal due to sale of the underlying prop-
            erty, refinancing, or
 
                                                                             27

            foreclosure, net of fees and costs which may be incurred) may ex-
            pose a Fund to a lower rate of return upon reinvestment of princi-
            pal. Also, if a security subject to prepayment has been purchased
            at a premium, the value of the premium would be lost in the event
            of prepayment. Like other fixed income securities, when interest
            rates rise, the value of a mortgage-related security generally
            will decline; however, when interest rates are declining, the
            value of mortgage-related securities with prepayment features may
            not increase as much as other fixed income securities. The rate of
            prepayments on underlying mortgages will affect the price and vol-
            atility of a mortgage-related security, and may have the effect of
            shortening or extending the effective maturity of the security be-
            yond what was anticipated at the time of purchase. To the extent
            that unanticipated rates of prepayment on underlying mortgages in-
            crease the effective maturity of a mortgage-related security, the
            volatility of such security can be expected to increase.
               Payment of principal and interest on some mortgage pass-through
            securities (but not the market value of the securities themselves)
            may be guaranteed by the full faith and credit of the U.S. Govern-
            ment (in the case of securities guaranteed by the Government Na-
            tional Mortgage Association ("GNMA")); or guaranteed by agencies
            or instrumentalities of the U.S. Government (in the case of secu-
            rities guaranteed by the Federal National Mortgage Association
            ("FNMA") or the Federal Home Loan Mortgage Corporation ("FHLMC"),
            which are supported only by the discretionary authority of the
            U.S. Government to purchase the agency's obligations). Mortgage-
            related securities created by non-governmental issuers (such as
            commercial banks, savings and loan institutions, private mortgage
            insurance companies, mortgage bankers and other secondary market
            issuers) may be supported by various forms of insurance or guaran-
            tees, including individual loan, title, pool and hazard insurance
            and letters of credit, which may be issued by governmental enti-
            ties, private insurers or the mortgage poolers.
 
            COLLATERALIZED MORTGAGE OBLIGATIONS ("CMOs") are hybrid mortgage-
            related instruments. Similar to a bond, interest and pre-paid
            principal on a CMO are paid, in most cases, semi-annually. CMOs
            may be collateralized by whole mortgage loans but are more typi-
            cally collateralized by portfolios of mortgage pass-through secu-
            rities guaranteed by GNMA, FHLMC, or FNMA. CMOs are structured
            into multiple classes, with each class bearing a different stated
            maturity. Monthly payments of principal, including prepayments,
            are first returned to investors holding the shortest maturity
            class; investors holding the longer maturity classes receive prin-
            cipal only after the first class has been retired. CMOs that are
            issued or guaranteed by the U.S. Government or by any of its agen-
            cies or instrumentalities will be considered U.S. Government secu-
            rities by a Fund, while other CMOs, even if collateralized by U.S.
            Government securities, will have the same status as other pri-
            vately issued securities for purposes of applying the Fund's di-
            versification tests.
 
            COMMERCIAL MORTGAGE-BACKED SECURITIES include securities that re-
            flect an interest in, and are secured by, mortgage loans on com-
            mercial real property. The market for commercial mortgage-backed
            securities developed more recently and in terms of total outstand-
            ing principal amount of issues is relatively small compared to the
            market for residential single-family mortgage-backed securities.
            Many of the risks of investing in commercial mortgage-backed secu-
            rities reflect the risks of investing in the real estate securing
            the underlying mortgage loans. These risks reflect the effects of
            local and other economic conditions on real estate markets, the
            ability of tenants to make loan payments, and the ability of a
            property to attract and retain tenants. Commercial mortgage-backed
            securities may be less liquid and exhibit greater price volatility
            than other types of mortgage-related or asset-backed securities.
 
            MORTGAGE-RELATED SECURITIES include securities other than those
            described above that directly or indirectly represent a participa-
            tion in, or are secured by and payable from, mortgage loans on
            real property, such as CMO residuals or stripped mortgage-backed
            securities ("SMBS"), and may be structured in classes with rights
            to receive varying proportions of principal and interest.
               A common type of SMBS will have one class receiving some of the
            interest and most of the principal from the mortgage assets, while
            the other class will receive most of the interest and the remain-
            der of the principal. In the most extreme case, one class will re-
            ceive all of the interest (the interest-only, or "IO" class),
            while the other class will receive

            all of the principal (the principal-only, or "PO" class). The
            yield to maturity on an IO class is extremely sensitive to the
            rate of principal payments (including prepayments) on the related
            underlying mortgage assets, and a rapid rate of principal payments
            may have a material adverse effect on the Fund's yield to maturity
            from these securities. The Balanced Fund has adopted a policy un-
            der which it will not invest more than 5% of its net assets in any
            combination of IO, PO, or inverse floater securities. For a dis-
            cussion of the characteristics of some of these instruments, see
            the Statement of Additional Information.
 
 
TAX EXEMPT  The Tax Exempt Fund invests in Tax Exempt Bonds which are gener-
BONDS       ally issued by states and local governments and their agencies,
            authorities and other instrumentalities. Tax Exempt Bonds are sub-
            ject to credit and market risk. Credit risk relates to the ability
            of the issuer to make payments of principal and interest. The is-
            suer of a Tax Exempt Bond may make such payments from money raised
            through a variety of sources, including (1) the issuer's general
            taxing power, (2) a specific type of tax, or (3) a particular fa-
            cility or project. The ability of an issuer to make such payments
            could be affected by litigation, legislation or other political
            events or the bankruptcy of the issuer. Market risk relates to
            changes in a security's value as a result of changes in interest
            rates. Lower rated Tax Exempt Bonds generally provide higher
            yields but are subject to greater credit and market risk than
            higher quality Tax Exempt Bonds.
 
 
CONVERTIBLE Many of the Funds may invest in convertible securities. Convert-
SECURITIES  ible securities are generally preferred stocks or fixed income se-
            curities that are convertible into common stock at either a stated
            price or a stated rate. The price of the convertible security will
            normally vary in some proportion to changes in the price of the
            underlying common stock because of this conversion feature. A con-
            vertible security will normally also provide a fixed income
            stream. For this reason, the convertible security may not decline
            in price as rapidly as the underlying common stock.
               A Fund's Portfolio Manager will select convertible securities
            to be purchased by the Fund based primarily upon its evaluation of
            the fundamental investment characteristics and growth prospects of
            the issuer of the security. As a fixed income security, a convert-
            ible security tends to increase in market value when interest
            rates decline and to decrease in value when interest rates rise.
            While convertible securities generally offer lower interest or
            dividend yields than non-convertible fixed income securities of
            similar quality, their value tends to increase as the market value
            of the underlying stock increases and to decrease when the value
            of the underlying stock decreases.
               The Renaissance Fund may invest in so-called "synthetic con-
            vertible securities," which are composed of two or more different
            securities whose investment characteristics, taken together, re-
            semble those of convertible securities. For example, the Renais-
            sance Fund may purchase a non-convertible debt security and a war-
            rant or option. The synthetic convertible differs from the true
            convertible security in several respects. Unlike a true convert-
            ible security, which is a single security having a unitary market
            value, a synthetic convertible comprises two or more separate se-
            curities, each with its own market value. Therefore, the "market
            value" of a synthetic convertible is the sum of the values of its
            fixed income component and its convertible component. For this
            reason, the values of a synthetic convertible and a true convert-
            ible security may respond differently to market fluctuations.
 
 
RISKS OF    The Renaissance, Growth, Balanced and Tax Exempt Funds may invest
HIGH YIELD  a portion of their assets in fixed income securities rated lower
SECURITIES  than Baa by Moody's or lower than BBB by S&P but rated at least B
("JUNK      by Moody's or S&P or, if not rated, determined by the Portfolio
BONDS")     Manager to be of comparable quality. Securities rated lower than
            Baa by Moody's or lower than BBB by S&P are sometimes referred to
            as "high yield" or "junk" bonds. Investors should consider the
            risks associated with high yield securities before investing in
            these Funds.
               Investing in high yield securities involves special risks in
            addition to the risks associated with investments in higher rated
            fixed income securities. While offering a greater potential oppor-
            tunity for capital appreciation and higher yields than investments
            in higher rated debt securities, high yield securities typically
            entail greater potential price volatility and may be less liquid
            than investment grade debt. High yield securities may be regarded
            as predominately speculative with respect to the issuer's continu-
            ing ability to meet principal and interest payments. Analysis of
            the
                                                      March 5, 1997 Prospectus
                                                                              29

            creditworthiness of issuers of high yield securities may be more
            complex than for issuers of higher quality debt securities, and
            achievement of a Fund's investment objective may, to the extent of
            its investments in high yield securities, depend more heavily on
            the Portfolio Manager's creditworthiness analysis than would be
            the case if the Fund were investing in higher quality securities.
            High yield securities may be more susceptible to real or perceived
            adverse economic and competitive industry conditions than higher
            grade securities.
               The following chart provides information on the weighted aver-
            age percentage of rated and unrated debt or fixed income securi-
            ties in the portfolios of each Fund that invested at least 5% of
            its average assets in high yield securities during the Fund's most
            recent fiscal year. The numerical rating designations correspond
            to the associated rating categories. The designation "1st" corre-
            sponds to the top rating category (i.e., Aaa by Moody's and/or AAA
            by S&P), "2nd" corresponds to the second highest rating category
            (i.e., Aa by Moody's and/or AA by S&P), etc. For a description of
            these rating categories, see the Appendix to the Statement of Ad-
            ditional Information. The columns related to unrated securities
            present the percentage of a Fund's total net assets invested dur-
            ing such fiscal year (1) in unrated high yield securities believed
            by the Advisor or the relevant Portfolio Manager to be equivalent
            in quality to fixed income securities of the indicated rating and
            (2) in all unrated fixed income securities.

DERIVATIVE  Certain Funds may purchase and write call and put options on secu-
INSTRUMENTS rities, securities indexes and foreign currencies, and enter into
            futures contracts and use options on futures contracts as further
            described below. In pursuit of their investment objectives, the
            Renaissance, Growth, Target, Opportunity, International Developed,
            International, Emerging Markets, Innovation, Precious Metals and
            Balanced Funds may engage in the purchase and writing of call and
            put options on securities and may engage in the purchase and writ-
            ing of options on securities indexes. The Tax Exempt Fund may pur-
            chase call or put options on U.S. Government securities, Tax Ex-
            empt Bonds and Tax Exempt Bond indexes. The Precious Metals Fund
            may purchase and write options on commodities indexes. The Funds
            that may invest in foreign-currency denominated securities may en-
            gage in the purchase and writing of call and put options on for-
            eign currencies. The International Developed, Emerging Markets and
            Balanced Funds may also enter into swap agreements with respect to
            securities indexes. The Balanced Fund may also enter into swap
            agreements with respect to foreign currencies and interest rates.
            The Funds may use these techniques to hedge against changes in in-
            terest rates, foreign currency exchange rates or securities pric-
            es; and for the International Developed, International and Emerg-
            ing Markets Funds, to increase exposure to a foreign currency, to
            shift exposure to foreign currency fluctuations from one country
            to another, or as part of their overall investment strategies.
            Each Fund will maintain a segregated account consisting of assets
            determined to be liquid by the Advisor or a Portfolio Manager in
            accordance with procedures

            established by the Board of Trustees (or, as permitted by applica-
            ble regulation, enter into certain offsetting positions) to cover
            its obligations under options, futures, and swaps to avoid
            leveraging of the Fund.
               For these purposes, derivative instruments are deemed to con-
            sist of securities or other instruments whose value is derived
            from or related to the value of some other instrument or asset,
            and not to include those securities whose payment of principal
            and/or interest depend upon cash flows from underlying assets,
            such as mortgage-related or asset-backed securities. See "Mort-
            gage-Related and Other Asset-Backed Securities." The value of some
            derivative instruments in which the Funds invest may be particu-
            larly sensitive to changes in prevailing interest rates, and, like
            the other investments of the Funds, the ability of a Fund to suc-
            cessfully utilize these instruments may depend in part upon the
            ability of the Portfolio Manager to forecast interest rates and
            other economic factors correctly. If the Portfolio Manager incor-
            rectly forecasts such factors and has taken positions in deriva-
            tive instruments contrary to prevailing market trends, the Funds
            could be exposed to the risk of loss.
               The Funds might not employ any of the strategies described be-
            low, and no assurance can be given that any strategy used will
            succeed. If the Portfolio Manager incorrectly forecasts interest
            rates, market values or other economic factors in utilizing a de-
            rivatives strategy for a Fund, the Fund might have been in a bet-
            ter position if it had not entered into the transaction at all.
            The use of these strategies involves certain special risks, in-
            cluding a possible imperfect correlation, or even no correlation,
            between price movements of derivative instruments and price move-
            ments of related investments. While some strategies involving de-
            rivative instruments can reduce the risk of loss, they can also
            reduce the opportunity for gain or even result in losses by off-
            setting favorable price movements in related investments, or due
            to the possible inability of a Fund to purchase or sell a portfo-
            lio security at a time that otherwise would be favorable for it to
            do so, or the possible need for a Fund to sell a portfolio secu-
            rity at a disadvantageous time, because the Fund is required to
            maintain asset coverage or offsetting positions in connection with
            transactions in derivative instruments, and the possible inability
            of a Fund to close out or to liquidate its derivatives positions.
 
            OPTIONS ON SECURITIES, SECURITIES INDEXES, COMMODITY INDEXES AND
            CURRENCIES Certain Funds may purchase put options on securities.
            One purpose of purchasing put options is to protect holdings in an
            underlying or related security against a substantial decline in
            market value. These Funds may also purchase call options on secu-
            rities. One purpose of purchasing call options is to protect
            against substantial increases in prices of securities the Fund in-
            tends to purchase pending its ability to invest in such securities
            in an orderly manner. A Fund may sell put or call options it has
            previously purchased, which could result in a net gain or loss de-
            pending on whether the amount realized on the sale is more or less
            than the premium and other transaction costs paid on the put or
            call option which is sold. A Fund may write a call or put option
            only if the option is "covered" by the Fund holding a position in
            the underlying securities or by other means which would permit im-
            mediate satisfaction of the Fund's obligation as writer of the op-
            tion. Prior to exercise or expiration, an option may be closed out
            by an offsetting purchase or sale of an option of the same series.
               The purchase and writing of options involves certain risks.
            During the option period, the covered call writer has, in return
            for the premium on the option, given up the opportunity to profit
            from a price increase in the underlying security above the exer-
            cise price, but, as long as its obligation as a writer continues,
            has retained the risk of loss should the price of the underlying
            security decline. The writer of an option has no control over the
            time when it may be required to fulfill its obligation as a writer
            of the option. Once an option writer has received an exercise no-
            tice, it cannot effect a closing purchase transaction in order to
            terminate its obligation under the option and must deliver the un-
            derlying security at the exercise price. If a put or call option
            purchased by the Fund is not sold when it has remaining value, and
            if the market price of the underlying security remains equal to or
            greater than the exercise price (in the case of a put), or remains
            less than or equal to the exercise price (in the case of a call),
            the Fund will lose its entire investment in the option. Also,
            where a put or call option on a particular security is purchased
            to hedge against price movements in a related security, the price
            of the put or call option may move more or less than the price of
            the related security. There can be no assurance that a liquid mar-
            ket will exist when a Fund seeks to close out an option position.
                                                      March 5, 1997 Prospectus
                                                                              31

            Furthermore, if trading restrictions or suspensions are imposed on
            the options markets, a Fund may be unable to close out a position.
               For each of the Renaissance, Growth, Target, Opportunity, In-
            ternational, Innovation, and Precious Metals Funds, in the case of
            a written call option on a securities index, the Fund will own
            corresponding securities whose historic volatility correlates with
            that of the index.
               The International Developed, International, Emerging Markets,
            Precious Metals and Balanced Funds may buy or sell put and call
            options on foreign currencies as a hedge against changes in the
            value of the U.S. dollar (or another currency) in relation to a
            foreign currency in which a Fund's securities may be denominated.
            Currency options traded on U.S. or other exchanges may be subject
            to position limits which may limit the ability of a Fund to reduce
            foreign currency risk using such options. Over-the-counter options
            differ from traded options in that they are two-party contracts,
            with price and other terms negotiated between buyer and seller,
            and generally do not have as much market liquidity as exchange-
            traded options. The Funds may be required to treat as illiquid
            over-the-counter options purchased and securities being used to
            cover certain written over-the-counter options.
 
            SWAP AGREEMENTS The International Developed and Emerging Markets
            Funds may enter into equity index swap agreements for purposes of
            gaining exposure to the stocks making up an index of securities in
            a foreign market without actually purchasing those stocks. The
            Balanced Fund may enter into swap agreements to hedge against
            changes in interest rates, foreign currency exchange rates or se-
            curities prices. Swap agreements are two-party contracts entered
            into primarily by institutional investors for periods ranging from
            a few weeks to more than one year. In a standard swap transaction,
            two parties agree to exchange the returns (or differentials in
            rates of return) earned or realized on particular predetermined
            investments or instruments, which may be adjusted for an interest
            factor. The gross returns to be exchanged or "swapped" between the
            parties are generally calculated with respect to a "notional
            amount," i.e., the return on or increase in value of a particular
            dollar amount invested at a particular interest rate, or in a
            "basket" of securities representing a particular index.
               Most swap agreements entered into by the Funds calculate the
            obligations of the parties to the agreement on a "net basis." Con-
            sequently, a Fund's current obligations (or rights) under a swap
            agreement will generally be equal only to the net amount to be
            paid or received under the agreement based on the relative values
            of the positions held by each party to the agreement (the "net
            amount"). A Fund's current obligations under a swap agreement will
            be accrued daily (offset against amounts owed to the Fund), and
            any accrued but unpaid net amounts owed to a swap counterparty
            will be covered by the maintenance of a segregated account con-
            sisting of assets determined to be liquid by the Portfolio Manager
            in accordance with procedures established by the Board of Trustees
            to limit any potential leveraging of the Fund's portfolio. Obliga-
            tions under swap agreements so covered will not be construed to be
            "senior securities" for purposes of a Fund's investment restric-
            tion concerning senior securities. A Fund will not enter into a
            swap agreement with any single party if the net amount owed or to
            be received under existing contracts with that party would exceed
            5% of the Fund's assets.
               Whether a Fund's use of swap agreements will be successful in
            furthering its investment objective will depend on the Portfolio
            Manager's ability to predict correctly whether certain types of
            investments are likely to produce greater returns than other in-
            vestments. Because they are two-party contracts and because they
            may have terms of greater than seven days, swap agreements may be
            considered to be illiquid investments. Moreover, a Fund bears the
            risk of loss of the amount expected to be received under a swap
            agreement in the event of the default or bankruptcy of a swap
            agreement counterparty. The Funds will enter into swap agreements
            only with counterparties that meet certain standards for credit-
            worthiness (generally, such counterparties would have to be eligi-
            ble counterparties under the terms of the Funds' repurchase agree-
            ment guidelines). Certain restrictions imposed on the Funds by the
            Internal Revenue Code may limit the Funds' ability to use swap
            agreements. The swaps market is a relatively new market and is
            largely unregulated. It is possible that developments in the swaps
            market, including potential government regulation, could adversely
            affect a Fund's ability to terminate existing swap agreements or
            to realize amounts to be received under such agreements.

            FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS The Balanced
            Fund may invest in interest rate futures contracts and options
            thereon. The Precious Metals Fund may purchase and sell futures
            contracts on precious metals (such as gold), and purchase and
            write options on precious metals futures contracts. The Interna-
            tional Developed, International, Emerging Markets, Precious Metals
            and Balanced Funds may invest in stock index futures contracts and
            options thereon. The International Developed, International,
            Emerging Markets, Precious Metals and Balanced Funds may invest in
            foreign exchange futures contracts and options thereon ("futures
            options") that are traded on a U.S. or foreign exchange or board
            of trade, or similar entity, or quoted on an automated quotation
            system. The Tax Exempt Fund may purchase and sell futures con-
            tracts on U.S. Government securities and Tax Exempt Bonds, as well
            as purchase put and call options on such futures contracts. These
            Funds may engage in such futures transactions as an adjunct to
            their securities activities.
               There are several risks associated with the use of futures and
            futures options for hedging purposes. There can be no guarantee
            that there will be a correlation between price movements in the
            hedging vehicle and in the portfolio securities being hedged. An
            incorrect correlation could result in a loss on both the hedged
            securities in a Fund and the hedging vehicle, so that the portfo-
            lio return might have been greater had hedging not been attempted.
            There can be no assurance that a liquid market will exist at a
            time when a Fund seeks to close out a futures contract or a
            futures option position. Most futures exchanges and boards of
            trade limit the amount of fluctuation permitted in futures con-
            tract prices during a single day; once the daily limit has been
            reached on a particular contract, no trades may be made that day
            at a price beyond that limit. In addition, certain of these in-
            struments are relatively new and without a significant trading
            history. As a result, there is no assurance that an active second-
            ary market will develop or continue to exist. Lack of a liquid
            market for any reason may prevent a Fund from liquidating an unfa-
            vorable position, and the Fund would remain obligated to meet mar-
            gin requirements until the position is closed.
               The Funds will only enter into futures contracts or futures op-
            tions which are standardized and traded on a U.S. or foreign ex-
            change or board of trade, or similar entity, or quoted on an auto-
            mated quotation system. Each Fund will use financial futures con-
            tracts and related options only for "bona fide hedging" purposes,
            as such term is defined in applicable regulations of the Commodity
            Futures Trading Commission ("CFTC"), or, with respect to positions
            in financial futures and related options that do not qualify as
            "bona fide hedging" positions, will enter such positions only to
            the extent that aggregate initial margin deposits plus premiums
            paid by it for open futures option positions, less the amount by
            which any such positions are "in-the-money," would not exceed 5%
            of the Fund's net assets.
 
 
PRECIOUS    The Precious Metals Fund will concentrate its investments in the
METALS      precious metals industry. Prices of precious metals can be ex-
            pected to respond to changes in rates of inflation and to percep-
            tions of economic and political instability. The values of compa-
            nies engaged in precious metal-related activities whose securities
            are principally traded on foreign securities exchanges may also be
            affected by changes in the exchange rate between the relevant for-
            eign currency and the U.S. dollar. Based on historical experience,
            the prices of precious metals and of securities of companies en-
            gaged in precious metal-related activities may be subject to ex-
            treme fluctuations, reflecting wider economic or political insta-
            bility or for other reasons.
 
 
LOANS OF    For the purpose of achieving income, each Fund (with the exception
PORTFOLIO   of the Tax Exempt Fund) may lend its portfolio securities to bro-
SECURITIES  kers, dealers, and other financial institutions, provided: (i) the
            loan is secured continuously by collateral consisting of U.S. Gov-
            ernment securities, cash or cash equivalents (negotiable certifi-
            cates of deposit, bankers' acceptances or letters of credit) main-
            tained on a daily mark-to-market basis in an amount at least equal
            to the current market value of the securities loaned; (ii) the
            Fund may at any time call the loan and obtain the return of the
            securities loaned; (iii) the Fund will receive any interest or
            dividends paid on the loaned securities; and (iv) the aggregate
            market value of securities loaned will not at any time exceed the
            Fund's limitation on lending its portfolio securities. Each Fund's
            performance will continue to reflect changes in the value of the
            securities loaned and will also reflect the receipt of either in-
            terest, through investment of cash collateral by the Fund in per-
            missible investments, or a fee, if the collateral is U.S. Govern-
            ment securities. Securities lending involves the risk of loss of
            rights in the collateral or delay in recovery of
                                                      March 5, 1997 Prospectus
                                                                              33

            the collateral should the borrower fail to return the security
            loaned or become insolvent. The Funds may pay lending fees to the
            party arranging the loan.
 
 
SHORT SALES Each Fund may from time to time make short sales involving securi-
            ties held in the Fund's portfolio or which the Fund has the right
            to acquire without the payment of further consideration. Short
            sales expose the Fund to the risk that it will be required to pur-
            chase securities to cover its short position at a time when the
            securities 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 securi-
DELIVERY    ties for a fixed price at a future date beyond normal settlement
AND         time (forward commitments). When-issued transactions, delayed de-
FORWARD     livery purchases and forward commitments involve a risk of loss if
COMMITMENT  the value of the securities declines prior to the settlement date,
TRANSAC-    which risk is in addition to the risk of decline in the value of
TIONS       the Fund's other assets. No income accrues to the purchaser of
            such securities prior to delivery.
 
 
REPURCHASE  For the purposes of maintaining liquidity and achieving income,
AGREEMENTS  each Fund may enter into repurchase agreements, which entail the
            purchase of a portfolio-eligible security from a bank or broker-
            dealer that agrees to repurchase the security at the Fund's cost
            plus interest within a specified time (normally one day). If the
            party agreeing to repurchase should default, as a result of bank-
            ruptcy or otherwise, the Fund will seek to sell the securities
            which it holds, which action could involve procedural costs or de-
            lays 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 re-
            purchase agreements only as a cash management technique with re-
            spect to that portion of the portfolio maintained in cash. Each
            Fund will limit its investment in repurchase agreements maturing
            in more than seven days consistent with the Fund's policy on in-
            vestment in illiquid securities.
 
 
REVERSE     A reverse repurchase agreement may for some purposes be considered
REPURCHASE  borrowing that involves the sale of a security by a Fund and its
AGREEMENTS  agreement to repurchase the instrument at a specified time and
AND OTHER   price. The Fund will maintain a segregated account consisting of
BORROWINGS  assets determined to be liquid by the Advisor or Portfolio Manager
            in accordance with procedures established by the Board of Trustees
            to cover its obligations under reverse repurchase agreements. Re-
            verse repurchase agreements will be subject to the Funds' limita-
            tions on borrowings. A Fund also may borrow money for investment
            purposes subject to any policies of the Fund currently described
            in this Prospectus or in the Statement of Additional Information.
            Such a practice will result in leveraging of a Fund's assets. Lev-
            erage will tend to exaggerate the effect on net asset value of any
            increase or decrease in the value of a Fund's portfolio and may
            cause a Fund to liquidate portfolio positions when it would not be
            advantageous to do so.
 
 
PORTFOLIO   The length of time a Fund has held a particular security is not
TURNOVER    generally a consideration in investment decisions. The investment
            policies of a Fund may lead to frequent changes in the Fund's in-
            vestments, particularly in periods of volatile market movements. A
            change in the securities held by a Fund is known as "portfolio
            turnover." High portfolio turnover (e.g., over 100%) involves cor-
            respondingly greater expenses to a Fund, including brokerage com-
            missions or dealer mark-ups and other transaction costs on the
            sale of securities and reinvestments in other securities. Such
            sales may result in realization of taxable capital gains. See
            "Taxes." The portfolio turnover rate for each Fund which offered
            Class A, Class B or Class C shares prior to the date of this Pro-
            spectus is set forth under "Financial Highlights." Portfolio turn-
            over for the remaining Funds which offered Institutional or Admin-
            istrative Class shares prior to the date of this Prospectus is in-
            corporated by reference in the Statement of Additional Informa-
            tion.

ILLIQUID    Each of the Equity Income, Value, Capital Appreciation, Mid Cap
SECURITIES  Growth, Small Cap Value and Balanced Funds may invest in securi-
            ties that are illiquid, but will not acquire such securities if
            they would compose more than 10% of the value of the Fund's net
            assets (taken at market value at the time of investment), and will
            not invest in securities that are illiquid because they are sub-
            ject to legal or contractual restrictions on resale if such secu-
            rities would compose more than 5% of the value of the Fund's net
            assets (taken at market value at the time of investment). Each of
            the Renaissance, Growth, Target, Opportunity, International Devel-
            oped, International, Emerging Markets, Innovation, Precious Metals
            and Tax Exempt Funds may invest in securities that are illiquid so
            long as no more than 15% of the value of the Fund's net assets
            (taken at market value at the time of investment) would be in-
            vested in such securities. Certain illiquid securities may require
            pricing at fair value as determined in good faith under the super-
            vision of the Board of Trustees. A Portfolio Manager may be sub-
            ject to significant delays in disposing of illiquid securities,
            and transactions in illiquid securities may entail registration
            expenses and other transaction costs that are higher than transac-
            tions in liquid securities.
               The term "illiquid securities" for this purpose means securi-
            ties that cannot be disposed of within seven days in the ordinary
            course of business at approximately the amount at which a Fund has
            valued the securities. Illiquid securities are considered to in-
            clude, among other things, written over-the-counter options, secu-
            rities or other liquid assets being used as cover for such op-
            tions, repurchase agreements with maturities in excess of seven
            days, certain loan participation interests, fixed time deposits
            which are not subject to prepayment or provide for withdrawal pen-
            alties upon prepayment (other than overnight deposits), securities
            that are subject to legal or contractual restrictions on resale
            (such as privately placed debt securities), and other securities
            whose disposition is restricted under the federal securities laws
            (other than securities issued pursuant to Rule 144A under the Se-
            curities Act of 1933 and certain commercial paper that the Advisor
            or a Portfolio Manager has determined to be liquid under proce-
            dures approved by the Board of Trustees).
 
INVESTMENT  The International Developed, International and Emerging Markets
IN          Funds may invest in securities of other investment companies, such
INVESTMENT  as closed-end management investment companies, or in pooled ac-
COMPANIES   counts or other investment vehicles which invest in foreign mar-
            kets. As a shareholder of an investment company, these Funds may
            indirectly bear service and other fees which are in addition to
            the fees the Funds pay their service providers.
 
 
CREDIT AND  All fixed income securities are subject to market risk and credit
MARKET RISK risk. Market risk relates to market-induced changes in a
OF          security's value, usually as a result of changes in interest
FIXEDINCOME rates. The value of a Fund's investments in fixed income securi-
SECURITIES  ties will change as the general level of interest rates fluctuate.
            During periods of falling interest rates, the value of a Fund's
            fixed income securities generally rise. Conversely, during periods
            of rising interest rates, the value of a Fund's fixed income secu-
            rities generally decline. Credit risk relates to the ability of
            the issuer to make payments of principal and interest.
        
"FUNDA-     The investment objective of each of the Renaissance, Growth, Tar-
MENTAL"     get, Opportunity, International, Innovation, Precious Metals and
POLICIES    Tax Exempt Funds described in this Prospectus may be changed by
            the Board of Trustees without shareholder approval. The investment
            objective of each other Fund is fundamental and may not be changed
            without shareholder approval by vote of a majority of the out-
            standing shares of that Fund. If there is a change in a Fund's in-
            vestment objective, including a change approved by shareholder
            vote, shareholders should consider whether the Fund remains an ap-
            propriate investment in light of their then current financial po-
            sition and needs.
 
            Performance Information
 
            From time to time the Trust may make available certain information
            about the performance of the Class A, Class B and Class C shares
            of some or all of the Funds. Information about a Fund's perfor-
            mance is based on that Fund's (or its
 
                                                                             35

            predecessor's) record to a recent date and is not intended to in-
            dicate future performance. Performance information is computed
            separately for each Fund's Class A, Class B and Class C shares in
            accordance with the formulas described below. Because Class B and
            Class C shares bear the expense of the distribution fee attending
            the deferred sales charge (Class B) and asset based sales charge
            (Class C) alternatives and certain other expenses, it is expected
            that, under normal circumstances, the level of performance of a
            Fund's Class B and Class C shares will be lower than that of the
            Fund's Class A shares, although an investment in Class B or Class
            C shares is not reduced by the front-end sales charge generally
            applicable to an investment in Class A shares.
               The total return of Class A, Class B and/or Class C shares of
            all Funds may be included in advertisements or other written mate-
            rial. When a Fund's total return is advertised with respect to its
            Class A, Class B and/or Class C shares, it will be calculated for
            the past year, the past five years, and the past ten years (or if
            the Fund has been offered for a period shorter than one, five or
            ten years, that period will be substituted) since the establish-
            ment of the Fund or its predecessor series of PIMCO Advisors
            Funds, as more fully described in the Statement of Additional In-
            formation. Consistent with Securities and Exchange Commission
            rules and informal guidance, for periods prior to the initial of-
            fering date of a particular class, total return presentations for
            the class will be based on the historical performance of an older
            class of the Fund (the older class to be used in each case is set
            forth in the Statement of Additional Information) restated to re-
            flect current sales charges (if any) of the newer class, but not
            reflecting any higher operating expenses (such as 12b-1 distribu-
            tion and servicing fees and administrative fee charges) associated
            with the newer class. All other things being equal, such higher
            expenses would have adversely affected (i.e., reduced) total re-
            turn for a newer class (i.e., if the newer class had been issued
            since the inception of the Fund) by the amount of such higher ex-
            penses, compounded over the relevant period. Total return for each
            class is measured by comparing the value of an investment in the
            Fund at the beginning of the relevant period (in the case of Class
            A shares, giving effect to the maximum initial sales charge) to
            the redemption value of the investment in the Fund at the end of
            the period (assuming immediate reinvestment of any dividends or
            capital gains distributions at net asset value and giving effect
            to the deduction of the maximum CDSC which would be payable). To-
            tal return may be advertised using alternative methods that re-
            flect all elements of return, but that may be adjusted to reflect
            the cumulative impact of alternative fee and expense structures,
            such as the currently effective advisory and administrative fees
            for the Funds.
               Quotations of yield for a Fund or class will be based on the
            investment income per share (as defined by the Securities and Ex-
            change Commission) during a particular 30-day (or one-month) pe-
            riod (including dividends and interest), less expenses accrued
            during the period ("net investment income"), and will be computed
            by dividing net investment income by the maximum public offering
            price per share on the last day of the period. The tax equivalent
            yield of the Tax Exempt Fund's Class A, Class B and Class C shares
            may also be advertised, calculated like yield except that, for any
            given tax bracket, net investment income will be calculated as the
            sum of (i) any taxable income of the class plus (ii) the tax ex-
            empt income of the class divided by the difference between 1 and
            the effective federal income tax rates for taxpayers in that tax
            bracket.
               Current distribution information may also be provided to the
            Trust's shareholders in shareholder reports or other shareholder
            communications, or in certain types of sales literature provided
            to prospective investors. Current distribution information for a
            particular class of a Fund will be based on distributions for a
            specified period (i.e., total dividends from net investment in-
            come), divided by the relevant class net asset value per share on
            the last day of the period and annualized. The rate of current
            distributions does not reflect deductions for unrealized losses
            from transactions in derivative instruments such as options and
            futures, which may reduce total return. Current distribution rates
            differ from standardized yield rates in that they represent what a
            class of Fund has declared and paid to shareholders as of the end
            of a specified period rather than the Fund's actual net investment
            income for that period.
               The Advisor and each Portfolio Manager may also report to
            shareholders or to the public in advertisements concerning its
            performance as adviser to clients other than the Funds, and on its
            comparative performance or standing in relation to other money
            managers. Such comparative information may be compiled or provided
            by independent ratings services or by news organizations. Any per-
            formance information, whether related to the Funds, the Advisor or

            the Portfolio Managers, should be considered in light of the
            Fund's investment objectives and policies, characteristics and
            quality of the Funds, and the market conditions during the time
            period indicated, and should not be considered to be representa-
            tive of what may be achieved in the future.
               Investment results of the Funds will fluctuate over time, and
            any representation of the Funds' total return or yield for any
            prior period should not be considered as a representation of what
            an investor's total return or yield may be in any future period.
 
            How to Buy Shares
 
            Class A, Class B (except the Opportunity Fund) and Class C shares
            of each Fund of the Trust are continuously offered through the
            Trust's principal underwriter, PIMCO Funds Distribution Company
            (the "Distributor"), and through other firms which have dealer
            agreements with the Distributor ("participating brokers") or which
            have agreed to act as introducing brokers for the Distributor
            ("introducing brokers"). Except to the extent described under
            "Limited Offering of Shares of the Opportunity Fund to New Invest-
            ors" below, the Opportunity Fund is closed to new investors. See
            "Restrictions on Sales of and Exchanges for Shares of the Opportu-
            nity Fund." The Opportunity Fund does not offer Class B shares.
               There are two ways to purchase Class A, Class B or Class C
            shares: either 1) through your dealer or broker which has a dealer
            agreement with the Distributor; or 2) directly by mailing a PIMCO
            Funds Account Application (an "Account Application") with payment,
            as described below under the heading Direct Investment, to the
            Distributor (if no dealer is named in the Account Application, the
            Distributor may act as dealer).
               Each Fund (except the Opportunity Fund) currently offers and
            sells three classes of shares in this Prospectus (Class A, Class B
            and Class C). The Opportunity Fund does not offer Class B shares.
            Institutional Class and Administrative Class shares of certain of
            the Funds are offered through a separate prospectus. Shares may be
            purchased at a price equal to their net asset value per share next
            determined after receipt of an order, plus a sales charge which,
            at the election of the purchaser, may be imposed either (i) at the
            time of the purchase in the case of Class A shares (the "initial
            sales charge alternative"), (ii) on a contingent deferred basis in
            the case of Class B shares (the "deferred sales charge alterna-
            tive"), or (iii) by the deduction of an ongoing asset based sales
            charge in the case of Class C shares (the "asset based sales
            charge alternative"). In certain circumstances, Class A and Class
            C shares are also subject to a CDSC. See "Alternative Purchase Ar-
            rangements." Purchase payments for Class B and Class C shares are
            fully invested at the net asset value next determined after ac-
            ceptance of the trade. Purchase payments for Class A shares, less
            the applicable sales charge, are invested at the net asset value
            next determined after acceptance of the trade.
               All purchase orders received by the Distributor prior to the
            close of regular trading (normally 4:00 p.m. Eastern time) on the
            New York Stock Exchange (the "Exchange"), on a regular business
            day, are processed at that day's offering price. However, orders
            received by the Distributor from dealers or brokers after the of-
            fering price is determined that day will receive such offering
            price if the orders were received by the dealer or broker from its
            customer prior to such determination and were transmitted to and
            received by the Distributor prior to its close of business that
            day (normally 5:00 p.m. Eastern time) or, in the case of certain
            retirement plans, received by the Distributor prior to 10:00 a.m.
            Eastern time on the next business day. Purchase orders received on
            other than a regular business day will be executed on the next
            succeeding regular business day. The Distributor, in its sole dis-
            cretion, may accept or reject any order for purchase of Fund
            shares. The sale of shares will be suspended during any period in
            which the Exchange is closed for other than weekends or holidays,
            or if permitted by the rules of the Securities and Exchange Com-
            mission, 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 as-
            sets, or during any other period as permitted by the Securities
            and Exchange Commission for the protection of investors.

               Except for gifts to minors or purchases through the PIMCO Auto
            Invest plan, the PIMCO Auto Exchange plan and tax-qualified pro-
            grams referred to below, the minimum initial investment in Class
            A, Class B or Class C shares of the Trust and series of PIMCO

            Fund. The minimum initial investment for gifts to minors is $250
            per Fund. For information about dealer commissions, see "Alterna-
            tive Purchase Arrangements" below. Persons selling Fund shares may
            receive different compensation for selling Class A, Class B or
            Class C shares. Normally, Fund shares purchased through partici-
            pating brokers are held in the investor's account with that bro-
            ker. No share certificates will be issued unless specifically re-
            quested in writing by an investor or broker-dealer.

INVESTMENT  of the Trust directly, rather than through a participating broker,
            may do so by opening an account with the Distributor. To open an
            account, an investor should complete the Account Application. All

            chase, redemption, dividend reinvestment, exchange or transfer of
            Trust shares, including the total number of Trust shares owned as
            of the confirmation date, except that purchases which result from
            the reinvestment of daily-accrued dividends and/or distributions
            will be confirmed once each calendar quarter. See "Distributions"
            below. Information regarding direct investment or any other fea-
            tures or plans offered by the Trust may be obtained by calling the

INVEST      the shareholder's account with the Trust by means of automatic
            transfers of a designated amount from the shareholder's bank ac-
            count. Investments may be made monthly or quarterly, and may be in
            any amount subject to a minimum of $50 per month for each Fund in
            which shares are purchased through the plan. Further information
            regarding the PIMCO Auto Invest plan is available from the Dis-
            tributor or participating brokers. You may enroll by completing

PIMCO AUTO  The PIMCO Auto Exchange plan establishes regular, periodic ex-
EXCHANGE    changes from one Fund to another Fund or a series of PIMCO Funds:
            Pacific Investment Management Series which offers Class A, Class B
            or Class C shares. The plan provides for regular investments into
            a shareholder's account in a specific Fund by means of automatic
            exchanges of a designated amount from another Fund account of the
            same class of shares and with identical account registration. Ex-
            changes for shares of the Opportunity Fund are currently re-
            stricted to the extent provided under "Limited Offering of Shares
            of the Opportunity Fund to New Investors" and "Restrictions on
            Sales of and Exchanges for Shares of the Opportunity Fund" below.
               Exchanges may be made monthly or quarterly, and may be in any
            amount subject to a minimum of $50 for each Fund whose shares are
            purchased through the plan. Further information regarding the
            PIMCO Auto Exchange plan is available from the Distributor at 800-
            426-0107 or participating brokers. You may enroll by completing an

            phone request at 800-426-0107. For more information on exchanges,
            see "Exchange Privilege."
 
 
PIMCOFUND   PIMCO Fund Link ("Fund Link") connects your Fund account with a
LINK        bank account. Fund Link may be used for subsequent purchases and
            for redemptions and other transactions described under "How to Re-
            deem." Purchase transactions are effected by electronic funds
            transfers from the shareholder's account at a U.S. bank or other
            financial institution that is an Automated Clearing House ("ACH")
            member. Investors may use Fund Link to make subsequent purchases
            of shares in amounts from $50 to $10,000. To initiate such pur-
            chases, call 800-852-8457. All such calls will be recorded. Fund
            Link is normally established within 45 days of receipt of a Fund
            Link Application by Shareholder Services, Inc. (the "Transfer
            Agent"). The minimum investment by Fund Link is $50 per Fund.
            Shares will be purchased on the regular business day the Distribu-
            tor receives the funds through the ACH system, provided the funds
            are received before the close of regular trading on the Exchange.
            If the funds are received after the close of regular trading, the
            shares will be purchased on the next regular business day.
               Fund Link privileges must be requested on the Account Applica-
            tion. To establish Fund Link on an existing account, complete a
            Fund Link Application, which is available from the Distributor or
            your broker, with signatures guaranteed from all shareholders of
            record for the account. See "Signature Guarantee" below. Such
            privileges apply to each shareholder of record for the account un-
            less and until the Distributor receives written instructions from
            a shareholder of record canceling such privileges. Changes of bank
            account information must be made by completing a new Fund Link Ap-
            plication signed by all owners of record of the account, with all
            signatures guaranteed. The Distributor, the Transfer Agent and the
            Fund may rely on any telephone instructions believed to be genuine
            and will not be responsible to shareholders for any damage, loss
            or expenses arising out of such instructions. The Fund reserves
            the right

            to amend, suspend or discontinue Fund Link privileges at any time

            LIMITED OFFERING OF SHARES OF THE OPPORTUNITY FUND TO NEW INVEST-
            ORS As described below under "Restrictions on Sales of and Ex-
            changes for Shares of the Opportunity Fund," shares of the Oppor-
            tunity Fund are normally not available for purchase by new invest-
            ors in the Fund. However, on January 27, 1997, the Opportunity
            Fund began offering Class A shares and, subsequently, Class C
            shares to new investors (the "Offering") on a limited basis as de-
            scribed below.
               With the exception of certain benefit plans not currently eli-
            gible to acquire Opportunity Fund shares, all investors eligible
            to purchase shares of other Funds of the Trust may participate in
            the Offering. Existing Class A shareholders and Class C sharehold-
            ers of other Funds of the Trust or series of PIMCO Funds: Pacific
            Investment Management Series may, in addition to purchasing
            shares, acquire Opportunity Fund shares during the Offering by ex-
            changing their Class A or Class C shares for the same class of Op-
            portunity Fund shares in the manner described under "Exchange
            Privilege" below.
               The Offering will close (and the Opportunity Fund will again be
            closed to new investors) at the close of business on the day (the
            "Closing Date") on which an aggregate gross amount of $250 million
            of the Fund's Class A and Class C shares has been sold to new in-
            vestors (including shares acquired through exchanges as described
            above). Shares purchased and subsequently redeemed during the Of-
            fering will not be resold during the Offering. All purchase orders
            for the Opportunity Fund's shares received on the Closing Date
            will be honored even if the result would be to exceed the $250
            million limit.
               For additional information regarding the terms of the Offering,
            please contact the Distributor (at 800-426-0107) or your broker.
 
            RESTRICTIONS ON SALES OF AND EXCHANGES FOR SHARES OF THE OPPORTU-
            NITY FUND Except to the extent described under "Limited Offering
            of Shares of the Opportunity Fund to New Investors" above, shares
            of the Opportunity Fund are not available for purchase by new in-
            vestors in the Fund. The following categories of existing share-
            holders will still be permitted to purchase additional shares of
            the Fund: (i) shareholders who owned shares of the Opportunity
            Fund on December 31, 1992 will be permitted to purchase additional
            shares of the Fund for as long as they continue to own some shares
            of the Fund; (ii) participants in any self-directed qualified ben-
            efit plan (for example, 401(k), 403(b) and Keogh Plans, but not
            IRAs or SEP IRAs) that owned Opportunity Fund shares on March 1,
            1993 for any single plan participant will be eligible to direct
            the purchase of the Fund's shares by their plan account for so
            long as the plan continues to own some shares of the Fund for any
            single plan participant; and (iii) shareholders who acquired
            shares during the Offering described under "Limited Offering of

            they continue to own some shares of the Fund. In the event a
            shareholder redeems all of his or her shares of the Opportunity
            Fund, or all participants in a self-directed qualified benefit
            plan described above redeem their shares of the Opportunity Fund,
            such shareholder, or the participants in such plan, will no longer
            be eligible to purchase shares of the Opportunity Fund. The Oppor-
            tunity Fund does not offer Class B shares to new or existing in-
            vestors.
               Shareholders of other Funds are not permitted to exchange any
            of their shares for Opportunity Fund shares unless the sharehold-
            ers are independently eligible to purchase Opportunity Fund shares
            because they already owned such shares of the Fund on December 31,
            1992 (March 1, 1993, in the case of the self-directed qualified
            benefit plans described above) or acquired such shares during the
            Offering described under "Limited Offering of Shares of the Oppor-
            tunity Fund to New Investors" above.
               The Trust reserves the right at any time to modify these re-
            strictions, including the suspension of all sales of Opportunity
            Fund shares or the lifting of restrictions on different classes of
            investors and/or transactions.

            Alternative Purchase Arrangements
 
            The Trust offers investors three classes of shares in this Pro-
            spectus (Class A, Class B and Class C) which bear sales charges in
            different forms and amounts and which bear different levels of ex-
            penses. Through a separate prospectus, certain of the Funds offer
            up to two additional classes of shares, Institutional Class shares
            and Administrative Class shares, to pension and profit sharing
            plans, employee benefit trusts, endowments, foundations, corpora-
            tions and other high net worth individuals. Institutional Class
            shares and Administrative Class shares are sold without sales
            charges and have different expenses than Class A, Class B and
            Class C shares. As a result of lower sales charges and/or operat-
            ing expenses, Administrative Class and Institutional Class shares
            are generally expected to achieve a higher investment return than
            Class A, Class B or Class C shares. To obtain more information
            about Institutional Class or Administrative Class shares, please
            call the Distributor at 800-426-0107.
               The alternative purchase arrangements offered in this Prospec-
            tus are designed to enable a retail investor to choose the method
            of purchasing Fund shares that is most beneficial to the investor
            based on all factors to be considered, which include: the amount
            and intended length of the investment; the particular Fund; and
            whether the investor intends to exchange shares for shares of
            other Funds. Generally, when making an investment decision, in-
            vestors should consider the anticipated life of an intended in-
            vestment in the Funds, the accumulated distribution and servicing
            fees plus CDSCs on Class B or Class C shares, the initial sales
            charge plus accumulated servicing fees on Class A shares (plus a
            CDSC in certain circumstances), the possibility that the antici-
            pated higher return on Class A shares due to the lower ongoing
            charges will offset the initial sales charge paid on such shares,
            the automatic conversion of Class B shares to Class A shares and
            the difference in the CDSCs applicable to Class A, Class B and
            Class C shares.
 
            CLASS A The initial sales charge alternative (Class A) might be
            preferred by investors purchasing shares of sufficient aggregate
            value to qualify for reductions in the initial sales charge appli-
            cable to such shares. Similar reductions are not available on the
            contingent deferred sales charge alternative (Class B) or the as-
            set based sales charge alternative (Class C). Class A shares are
            subject to a servicing fee but are not subject to a distribution
            fee and, accordingly, such shares are expected to pay correspond-
            ingly higher dividends on a per share basis. However, because ini-
            tial sales charges are deducted at the time of purchase, not all
            of the purchase payment for Class A shares is invested initially.
            Class B and Class C shares might be preferable to investors who
            wish to have all purchase payments invested initially, although
            remaining subject to higher distribution and servicing fees and,
            for certain periods, being subject to a CDSC. An
 
                                                                             41

            investor who qualifies for an elimination of the Class A initial
            sales charge should also consider whether he or she anticipates
            redeeming shares in a time period which will subject such shares
            to a CDSC as described below. See "Initial Sales Charge Alterna-
            tive--Class A Shares--Class A Deferred Sales Charge" below.
 
            CLASS B Class B shares might be preferred by investors who intend
            to invest in the Funds for longer periods and who do not intend to
            purchase shares of sufficient aggregate value to qualify for sales
            charge reductions applicable to Class A shares. Both Class B and
            Class C shares can be purchased at net asset value without an ini-
            tial sales charge. However, unlike Class C shares, Class B shares
            convert into Class A shares after the shares have been held for
            seven years. After the conversion takes place, the shares will no
            longer be subject to a CDSC, and will be subject to the servicing
            fees charged for Class A shares which are lower than the distribu-
            tion and servicing fees charged on either Class B or Class C
            shares. See "Deferred Sales Charge Alternative -- Class B Shares"
            below.
 
            CLASS C Class C shares might be preferred by investors who intend
            to purchase shares which are not of sufficient aggregate value to
            qualify for Class A sales charges of 1% or less and who wish to
            have all purchase payments invested initially. Class C shares are
            preferable to Class B shares for investors who intend to maintain
            their investment for intermediate periods and therefore may also
            be preferable for investors who are unsure of the intended length
            of their investment. Unlike Class B shares, Class C shares are not
            subject to a CDSC after they have been held for one year and are
            subject to only a 1% CDSC during the first year. However, because
            Class C shares do not convert into Class A shares, Class B shares
            are preferable to Class C shares for investors who intend to main-
            tain their investment in the Funds for long periods. See "Asset
            Based Sales Charge Alternative--Class C Shares" below.
               In determining which class of shares to purchase, an investor
            should always consider whether any waiver or reduction of a sales
            charge or a CDSC is available. See generally "Initial Sales Charge
            Alternative--Class A Shares" and "Waiver of Contingent Deferred
            Sales Charges" below.
               The maximum single purchase of Class B shares of the Trust and
            series of PIMCO Funds: Pacific Investment Management Series ac-
            cepted is $249,999. The maximum single purchase of Class C shares
            of the Trust and series of PIMCO Funds: Pacific Investment Manage-
            ment Series accepted is $999,999. The Funds may refuse any order
            to purchase shares.
               For a description of the Distribution and Servicing Plans and
            distribution and servicing fees payable thereunder with respect to
            Class A, Class B and Class C shares, see "Distributor and Distri-
            bution and Servicing Plans" below.
 
            WAIVER OF CONTINGENT DEFERRED SALES CHARGES The CDSC applicable to
            Class A and Class C shares is currently waived for (i) any partial
            or complete redemption in connection with a distribution without
            penalty under Section 72(t) of the Internal Revenue Code of 1986,
            as amended (the "Code"), from a retirement plan, including a
            403(b)(7) plan or an IRA (a) upon attaining age 59 1/2, (b) as
            part of a series of substantially equal periodic payments, or (c)

            to another employer's plan or to an IRA; (iv) any partial or com-
            plete redemption following death or disability (as defined in the
            Code) of a shareholder (including one who owns the shares as joint
            tenant with his or her spouse) from an account in which the de-
            ceased or disabled is named, provided the redemption is requested
            within one year of the death or initial determination of disabili-
            ty; (v) any redemption resulting from a return of an excess con-
            tribution to a qualified employer retirement plan or an IRA; (vi)

            held in such shareholder's account is less than a minimum account
            size specified in such Fund's prospectus; (ix) involuntary redemp-
            tions caused by operation of law; (x) redemption of shares of any
            Fund that is combined with another Fund, investment company, or
            personal holding company by virtue of a merger, acquisition or
            other similar reorganization transaction; (xi) redemptions by a
            shareholder who is a participant making periodic purchases of not
            less than $50 through certain employer sponsored savings plans
            that are clients of a broker-dealer with which the Distributor has
            an agreement with respect to such purchases; (xii) redemptions ef-
            fected by trustees or other fiduciaries who have purchased shares
            for employer sponsored plans, the trustee, administrator, fiducia-

            Trust is the designated financial institution.

            any partial or complete redemption (a) in connection with a dis-
            tribution without penalty under Section 72(t) of the Code from a
            403(b)(7) plan or an IRA upon attaining age 59 1/2; (b) following
            death or disability (as defined in the Code) of a shareholder (in-
            cluding one who owns the shares as joint tenant with his or her
            spouse) from an account in which the deceased or disabled is
            named, provided the redemption is requested within one year of the
            death or initial determination of disability; and (c) of up to 10%

            1. As shown, investors that purchase more than $1,000,000 of any
            Fund's Class A shares will not pay any initial sales charge on
            such purchase. However, purchasers of $1,000,000 or more of Class
            A shares (other than those purchasers described below under "Sales
            at Net Asset Value" where no commission is paid) will be subject
            to a CDSC of 1% if such shares are redeemed during the first 18
            months after such shares are purchased unless such purchaser is
            eligible for a waiver of the CDSC as described under "Waiver of
            Contingent Deferred Sales Charges" above. See "Class A Deferred
            Sales Charge" below.
 
            2. The Distributor will pay a commission to dealers who sell
            amounts of $1,000,000 or more of Class A shares (or who sell Class
            A shares at net asset value to certain employer-sponsored plans as
            outlined in "Sales at Net Asset Value" below) of each Fund except
            the Tax Exempt Fund, according to the following schedule: 0.75% of
            the first $2,000,000, 0.50% of amounts from $2,000,001 to
            $5,000,000, and 0.25% of amounts over $5,000,000; and for Class A
            shares of the Tax Exempt Fund, according to the following sched-
            ule: 0.50% of the first $2,000,000, and 0.25% of amounts over
            $2,000,000.
 
               Each Fund receives the entire net asset value of its Class A
            shares purchased by investors. The Distributor receives the sales
            charge shown above less any applicable discount or commission
            "reallowed" to participating brokers in the amounts indicated in
            the table above. The Distributor may, however, elect to reallow
            the entire sales charge to participating brokers for all sales
            with respect to which orders are placed with the Distributor for
            any particular Fund during a particular period. During such peri-
            ods as may from time to time be designated by the Distributor, the
            Distributor will pay an additional amount of up to 0.50% of the
            purchase price on sales of Class A shares of all or selected Funds
            purchased to each participating broker which obtains purchase or-
            ders in amounts exceeding thresholds established from time to time
            by the Distributor. From time to time, the Distributor, its parent
            and/or its affiliates may make additional payments to one or more
            participating brokers based upon factors such as the level of
            sales or the length of time clients' assets have remained in the
            Trust.

 PIMCO Funds: Multi-Manager Series
<PAGE>
 
               Shares issued pursuant to the automatic reinvestment of income
            dividends or capital gains distributions are issued at net asset
            value and are not subject to any sales charges.
               Under the circumstances described below, investors may be enti-
            tled to pay reduced sales charges for Class A shares.
 
            COMBINED PURCHASE PRIVILEGE Investors may qualify for a reduced
            sales charge by combining purchases of the Class A shares of one
            or more Funds or series of PIMCO Funds: Pacific Investment Manage-
            ment Series which offer Class A shares (together, "eligible PIMCO
            Funds") into a "single purchase," if the resulting purchase totals
            at least $50,000. The term single purchase refers to: (i) a single
            purchase by an individual, or concurrent purchases, which in the
            aggregate are at least equal to the prescribed amounts, by an in-
            dividual, his or her spouse and their children under the age of 21
            years purchasing Class A shares of the eligible PIMCO Funds for
            his, her or their own account; (ii) a single purchase by a trustee
            or other fiduciary purchasing shares for a single trust, estate or
            fiduciary account although more than one beneficiary is involved;
            or (iii) a single purchase for the employee benefit plans of a
            single employer. For further information, call the Distributor at
            800-426-0107 or your broker.
 
            CUMULATIVE QUANTITY DISCOUNT (RIGHT OF ACCUMULATION) A purchase of
            additional Class A shares of any eligible PIMCO Fund may qualify
            for a Cumulative Quantity Discount at the rate applicable to the
            discount bracket obtained by adding:
                (i) the investor's current purchase;
                (ii) the value (at the close of business on the day of the
                current purchase) of all Class A shares of any eligible PIMCO
                Fund held by the investor computed at the maximum offering
                price; and
                (iii) the value of all shares described in paragraph (ii)
                owned by another shareholder eligible to be combined with the
                investor's purchase into a "single purchase" as defined above
                under "Combined Purchase Privilege."
               For example, if you owned Class A shares of the Tax Exempt Fund
            worth $25,000 at the current maximum offering price and wished to
            purchase Class A shares of the Growth Fund worth an additional
            $30,000, the sales charge for the $30,000 purchase would be at the
            4.50% rate applicable to a single $55,000 purchase of shares of
            the Growth Fund, rather than the 5.50% rate.
 
            LETTER OF INTENT An investor may also obtain a reduced sales
            charge by means of a written Letter of Intent, which expresses an
            intention to invest not less than $50,000 within a period of 13
            months in Class A shares of any eligible PIMCO Fund(s). Each pur-
            chase of shares under a Letter of Intent will be made at the pub-
            lic offering price or prices applicable at the time of such pur-
            chase to a single transaction of the dollar amount indicated in
            the Letter. At the investor's option, a Letter of Intent may in-
            clude purchases of Class A shares of any eligible PIMCO Fund made
            not more than 90 days prior to the date the Letter of Intent is
            signed; however, the 13-month period during which the Letter is in
            effect will begin on the date of the earliest purchase to be in-
            cluded and the sales charge on any purchases prior to the Letter
            will not be adjusted.
               Investors qualifying for the Combined Purchase Privilege de-
            scribed above may purchase shares of the eligible PIMCO Funds un-
            der a single Letter of Intent. For example, if at the time you
            sign a Letter of Intent to invest at least $100,000 in Class A
            shares of any Fund, you and your spouse each purchase Class A
            shares of the Growth Fund worth $30,000 (for a total of $60,000),
            it will only be necessary to invest a total of $40,000 during the
            following 13 months in Class A shares of any of the Funds to qual-
            ify for the 3.50% sales charge on the total amount being invested
            (the sales charge applicable to an investment of $100,000 in any
            of the Funds).
               A Letter of Intent is not a binding obligation to purchase the
            full amount indicated. The minimum initial investment under a Let-
            ter of Intent is 5% of such amount. Shares purchased with the
            first 5% of such amount will be held in escrow (while remaining
            registered in your name) to secure payment of the higher sales
            charge applicable to the shares actually purchased in the event
            the full intended amount is not purchased. If the full amount in-
            dicated is not purchased, a sufficient amount of such escrowed
            shares will be involuntarily redeemed to pay the additional sales
            charge
                                                      March 5, 1997 Prospectus
                                                                              45

            applicable to the amount actually purchased, if necessary. Divi-
            dends on escrowed shares, whether paid in cash or reinvested in
            additional eligible PIMCO Fund shares, are not subject to escrow.
            When the full amount indicated has been purchased, the escrow will
            be released.
               If you wish to enter into a Letter of Intent in conjunction
            with your initial investment in Class A shares of a Fund, you
            should complete the appropriate portion of the Account Applica-
            tion. If you are a current Class A shareholder desiring to do so
            you can obtain a form of Letter of Intent by contacting the Dis-
            tributor at 800-426-0107 or any broker participating in this pro-
            gram.
 
            REINSTATEMENT PRIVILEGE A Class A shareholder who has caused any
            or all of his shares to be redeemed may reinvest all or any por-
            tion of the redemption proceeds in Class A shares of any eligible
            PIMCO Fund at net asset value without any sales charge, provided
            that such reinvestment is made within 120 calendar days after the
            redemption or repurchase date. Shares are sold to a reinvesting
            shareholder at the net asset value next determined. See "How Net
            Asset Value is Determined." A reinstatement pursuant to this priv-
            ilege will not cancel the redemption transaction and, consequent-
            ly, any gain or loss so realized may be recognized for federal tax
            purposes except that no loss may be recognized to the extent that
            the proceeds are reinvested in shares of the same Fund within 30
            days. The reinstatement privilege may be utilized by a shareholder
            only once, irrespective of the number of shares redeemed, except
            that the privilege may be utilized without limit in connection
            with transactions whose sole purpose is to transfer a sharehold-
            er's interest in a Fund to his Individual Retirement Account or
            other qualified retirement plan account. An investor may exercise
            the reinstatement privilege by written request sent to the Dis-
            tributor or to the investor's broker.
 
            SALES AT NET ASSET VALUE Each Fund may sell its Class A shares at
            net asset value without a sales charge to (a) current or retired
            officers, trustees, directors or employees of the Trust, the Advi-
            sor or the Distributor, a parent, brother or sister of any such
            officer, trustee, director or employee or to a spouse or child of
            any of the foregoing persons, or to any trust, profit sharing or
            pension plan for the benefit of any such person, (b) current or
            retired trustees of PIMCO Funds: Pacific Investment Management Se-
            ries and Cash Accumulation Trust, registered investment companies
            for which the Advisor or an affiliate acts as investment adviser,
            (c) current registered representatives and other full-time employ-
            ees of participating brokers or such persons' spouses, (d) trust-
            ees or other fiduciaries purchasing shares for certain employer
            sponsored plans that have at least 100 eligible participants or at
            least $1 million in total plan assets, (e) trustees or other fidu-
            ciaries purchasing shares for certain employer-sponsored plans,
            the trustee, administrator, fiduciary, broker, trust company or
            registered investment adviser for which has an agreement with the
            Distributor with respect to such purchases, (f) participants in-
            vesting through accounts known as "wrap accounts" established with
            brokers or dealers approved by the Distributor where such brokers
            or dealers are paid a single, inclusive fee for brokerage and in-
            vestment management services, (g) broker-dealers or registered in-
            vestment advisers affiliated with such broker-dealers with which
            the Distributor has an agreement for the use of PIMCO Funds: Mul-
            ti-Manager Series in particular investment products for which a
            fee is charged, and (h) trust accounts for which trust companies
            affiliated with the Trust or the Advisor serve as trustee. As de-
            scribed above, the Distributor will not pay any initial commission
            to dealers upon the sale of Class A shares to the purchasers de-
            scribed in this paragraph except for sales to purchasers described
            under (d) or (e) in this paragraph.
 
            NOTIFICATION OF DISTRIBUTOR An investor or participating broker
            must notify the Distributor whenever a quantity discount or re-
            duced sales charge is applicable to a purchase and must provide
            the Distributor with sufficient information at the time of pur-
            chase to verify that each purchase qualifies for the privilege or
            discount. Upon such notification, the investor will receive the
            lowest applicable sales charge. The quantity discounts described
            above may be modified or terminated at any time.

            CLASS A DEFERRED SALES CHARGE For all Funds, investors who pur-
            chase $1,000,000 or more of Class A shares (and, thus, purchase
            such shares without any initial sales charge) may be subject to a
            1% CDSC (the "Class A CDSC") if such shares are redeemed within 18
            months of their purchase. The Class A CDSC does not apply to in-
            vestors purchasing $1,000,000 or more of any Fund's Class A shares
            if such investors are otherwise eligible to purchase Class A
            shares without any sales charge because they are described under
            "Sales at Net Asset Value" above.
               For purchases subject to the Class A CDSC, a 1% CDSC will apply
            for any redemption of such Class A shares that occurs within 18
            months of their purchase. No CDSC will be imposed if the shares
            redeemed have been acquired through the reinvestment of dividends
            or capital gains distributions or if the amount redeemed is de-
            rived from increases in the value of the account above the amount
            of purchase payments subject to the CDSC. In determining whether a
            CDSC is payable, it is assumed that Class A shares acquired
            through the reinvestment of dividends and distributions are re-
            deemed first, and thereafter that Class A shares that have been
            held by an investor for the longest period of time are redeemed
            first.
               The Class A CDSC is currently waived in connection with certain
            redemptions as described above under "Alternative Purchase Ar-
            rangements--Waiver of Contingent Deferred Sales Charges." For more
            information about the Class A CDSC, call the Distributor at 800-
            426-0107.
 
            PARTICIPATING BROKERS Investment dealers and other financial in-
            termediaries provide varying arrangements for their clients to
            purchase and redeem Fund shares. Some may establish higher minimum
            investment requirements than set forth above. Firms may arrange
            with their clients for other investment or administrative services
            and may independently establish and charge additional amounts to
            their clients for such services, which charges would reduce cli-
            ents' return. Firms also may hold Fund shares in nominee or street
            name as agent for and on behalf of their customers. In such in-
            stances, the Trust's transfer agent will have no information with
            respect to or control over accounts of specific shareholders. Such
            shareholders may obtain access to their accounts and information
            about their accounts only from their broker. In addition, certain
            privileges with respect to the purchase and redemption of shares
            or the reinvestment of dividends may not be available through such
            firms. Some firms may participate in a program allowing them ac-
            cess to their clients' accounts for servicing including, without
            limitation, transfers of registration and dividend payee changes;
            and may perform functions such as generation of confirmation
            statements and disbursement of cash dividends. This Prospectus
            should be read in connection with such firms' material regarding
            their fees and services.
 
DEFERRED    Class B shares are sold at their current net asset value without
SALES       any initial sales charge. The full amount of an investor's pur-
CHARGE      chase payment will be invested in shares of the Fund(s) selected.
ALTERNA-    A CDSC will be imposed on Class B shares if an investor redeems an
TIVE --     amount which causes the current value of the investor's account
CLASS B     for a Fund to fall below the total dollar amount of purchase pay-
SHARES      ments subject to the CDSC, except that no CDSC is imposed if the
            shares redeemed have been acquired through the reinvestment of
            dividends or capital gains distributions or if the amount redeemed
            is derived from increases in the value of the account above the
            amount of purchase payments subject to the CDSC. Class B shares
            are not available for purchase by employer sponsored retirement
            plans. The Opportunity Fund does not offer Class B shares.

               Whether a CDSC is imposed and the amount of the CDSC will de-

            *After the seventh year, Class B shares convert into Class A
            shares as described below.
 
               In determining whether a CDSC is payable, it is assumed that
            the purchase payment from which a redemption is made is the earli-
            est purchase payment from which a redemption or exchange has not
            already been fully effected.
               The following example will illustrate the operation of the
            Class B CDSC:
               Assume that an individual opens 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 distribu-
            tions 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 Class
            B shares in the shareholder's account with the particular Fund are
            aggregated, and the current value of all such shares is aggregat-
            ed. Any CDSC imposed on a redemption of Class B shares is paid to
            the Distributor.
               Class B shares are subject to higher distribution fees than
            Class A shares for a fixed period after their purchase, after
            which they automatically convert to Class A shares and are no
            longer subject to such higher distribution fees. Class B shares of
            each Fund automatically convert into Class A shares after they
            have been held for seven years.
               For sales of Class B shares made and services rendered to Class
            B shareholders, the Distributor intends to make payments to par-
            ticipating brokers, at the time a shareholder purchases Class B
            shares, of 4% of the purchase amount for each of the Funds. During
            such periods as may from time to time be designated by the Dis-
            tributor, the Distributor will pay selected participating brokers
            an additional amount of up to .50% of the purchase price on sales
            of Class B shares of all or selected Funds purchased to each par-
            ticipating broker which obtains purchase orders in amounts exceed-
            ing thresholds established from time to time by the Distributor.
               The Class B CDSC is currently waived in connection with certain
            redemptions as described above under "Alternative Purchase Ar-
            rangements --Waiver of Contingent Deferred Sales Charges." For
            more information about the Class B CDSC, call the Distributor at

               In determining whether a CDSC is payable, it is assumed that
            the purchase payment from which the redemption is made is the ear-
            liest purchase payment (from which a redemption or exchange has
            not already been effected).
               The following example will illustrate the operation of the
            Class C CDSC:
               Assume that an individual opens an account and makes a purchase
            payment of $10,000 for Class C shares of a Fund and that six
            months later the value of the investor's account for that Fund has
            grown through investment performance and reinvestment of distribu-
            tions 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 1%, the Class C CDSC would be $20.
               In determining whether an amount is available for redemption
            without incurring a CDSC, the purchase payments made for all Class
            C shares in the shareholder's account with the particular Fund are
            aggregated, and the current value of all such shares is aggregat-
            ed. Any CDSC imposed on a redemption of Class C shares is paid to
            the Distributor. Unlike Class B shares, Class C shares do not au-
            tomatically convert to any other class of shares of the Funds.
               Except as described below, for sales of Class C shares made and
            services rendered to Class C shareholders, the Distributor expects
            to make payments to participating brokers, at the time the share-
            holder purchases Class C shares, of 1.00% (representing .75% dis-
            tribution fees and .25% servicing fees) of the purchase amount for
            all Funds. For sales of Class C shares made to participants making
            periodic purchases of not less than $50 through certain employer
            sponsored savings plans which are clients of a broker-dealer with
            which the Distributor has an agreement with respect to such pur-
            chases, no payments are made at the time of purchase. During such
            periods as may from time to time be designated by the Distributor,
            the Distributor will pay an additional amount of up to .50% of the
            purchase price on sales of Class C shares of all or selected Funds
            purchased to each participating broker which obtains purchase or-
            ders in amounts exceeding thresholds established from time to time
            by the Distributor.
               The Class C CDSC is currently waived in connection with certain
            redemptions as described above under "Alternative Purchase Ar-
            rangements--Waiver of Contingent Deferred Sales Charges." For more
            information about the Class C CDSC, contact the Distributor at
            800-426-0107.
 
            Exchange Privilege
 
            Except with respect to exchanges for shares of the Opportunity
            Fund (which are currently subject to certain restrictions), a
            shareholder may exchange Class A, Class B and Class C shares of
            any Fund for the same Class of shares of any other Fund in an ac-
            count with identical registration on the basis of their respective
            net asset values. For information on restrictions applicable to
            exchanges of shares for shares of the Opportunity Fund, see "Lim-
            ited Offering of Shares of the Opportunity Fund to New Investors"
            and "Restrictions on Sales of and Exchanges for Shares of the Op-
            portunity Fund" under "How to Buy Shares" above. Class A, Class B
            and Class C shares of each Fund may also be exchanged for shares

            of the same class of a series of PIMCO Funds: Pacific Investment
            Management Series, an affiliated mutual fund family comprised pri-
            marily of fixed income portfolios managed by Pacific Investment
            Management, an affiliate of the Advisor. There are currently no
            exchange fees or charges. Except with respect to tax-qualified
            programs and exchanges effected through the PIMCO Auto Exchange
            plan, exchanges are subject to the $250 minimum initial purchase
            requirement for each Fund. An exchange will constitute a taxable
            sale for federal income tax purposes.
               Investors who maintain their account with the Distributor may
            exchange shares by a written exchange request sent to PIMCO Funds
            Distribution Company, P.O. Box 5866, Denver, CO 80217-5866 or, un-
            less the investor has specifically declined telephone exchange
            privileges on the Account Application or elected in writing not to
            utilize telephone exchanges, by a telephone request to the Trans-
            fer Agent at 800-852-8457. The Trust will employ reasonable proce-
            dures to confirm that instructions communicated by telephone are
            genuine, and may be liable for any losses due to unauthorized or
            fraudulent instructions if it fails to employ such procedures. The
            Trust will require a form of personal identification prior to act-
            ing on a caller's telephone instructions, will provide written
            confirmations of such transactions and will record telephone in-
            structions. Exchange forms are available from the Distributor at
            800-426-0107 and may be used if there will be no change in the
            registered name or address of the shareholder. Changes in regis-
            tration information or account privileges may be made in writing
            to the Transfer Agent, Shareholder Services, Inc., P.O. Box 5866,
            Denver, Colorado 80217-5866, or by use of forms which are avail-
            able from the Distributor. A signature guarantee is required. See
            "How to Buy Shares--Signature Guarantee." Telephone exchanges may
            be made between 9:00 a.m. Eastern time and the close of regular
            trading (normally 4:00 p.m. Eastern time) on the Exchange on any
            day the Exchange is open (generally weekdays other than normal
            holidays). The Trust reserves the right to refuse exchange pur-
            chases if, in the judgment of the Advisor, the purchase would ad-
            versely affect the Fund and its shareholders. In particular, a
            pattern of exchanges characteristic of "market-timing" strategies
            may be deemed by the Advisor to be detrimental to the Trust or a
            particular Fund. Although the Trust has no current intention of
            terminating or modifying the exchange privilege, it reserves the
            right to do so at any time. Except as otherwise permitted by Secu-
            rities and Exchange Commission regulations, the Trust will give 60
            days' advance notice to shareholders of any termination or mate-
            rial modification of the exchange privilege. For further informa-
            tion about exchange privileges, contact your participating broker
            or call the Transfer Agent at 800-426-0107.
               With respect to Class B and Class C shares, or Class A shares
            subject to a CDSC, if less than all of an investment is exchanged
            out of a Fund, any portion of the investment attributable to capi-
            tal appreciation and/or reinvested dividends or capital gains dis-
            tributions will be exchanged first, and thereafter any portions
            exchanged will be from the earliest investment made in the Fund
            from which the exchange was made. Shareholders should take into
            account the effect of any exchange on the applicability of any
            CDSC that may be imposed upon any subsequent redemption.
               Investors may also select the PIMCO Auto Exchange plan which
            establishes automatic periodic exchanges. For further information
            on automatic exchanges see "How to Buy Shares--PIMCO Auto Ex-
            change" above."
 
            How to Redeem
 
            Class A, Class B or Class C shares may be redeemed through a par-
            ticipating broker, by telephone, by submitting a written redemp-
            tion request directly to the Transfer Agent (for non-broker ac-
            counts), or through an Automatic Withdrawal Plan or PIMCO Fund
            Link. In the event a shareholder or participants in certain self-
            directed qualified employee benefit plans eligible to purchase
            shares of the Opportunity Fund redeem(s) all of the shareholder's
            or the participants' shares of the Fund (including shares acquired
            during the Offering described under "How to Buy Shares--Limited
            Offering of Shares of the Opportunity Fund to New Investors"
            above), such shareholder or participants in such plans will no
            longer be eligible to purchase shares of the Opportunity Fund. See
            "How to Buy Shares--Restrictions on Sales of and Exchanges for
            Shares of the Opportunity Fund."

              A CDSC may apply to a redemption of Class A, Class B or Class C
            shares. See "Alternative Purchase Arrangements" above. Shares are
            redeemed at their net asset value next determined after a proper
            redemption request has been received, less any applicable CDSC.
            There is no charge by the Distributor (other than an applicable
            CDSC) with respect to a redemption; however, a participating bro-
            ker who processes a redemption for an investor may charge custom-
            ary commissions for its services. Dealers and other financial
            services firms are obligated to transmit orders promptly. Requests
            for redemption received by dealers or other firms prior to the
            close of regular trading (normally 4:00 p.m. Eastern time) on the
            Exchange on a regular business day and received by the Distributor
            prior to the close of the Distributor's business day will be con-
            firmed at the net asset value effective as of the closing of the
            Exchange on that day, less any applicable CDSC.
 
 
DIRECT      A shareholder's original Account Application permits the share-
REDEMPTION  holder to redeem by written request and by telephone (unless the
            shareholder specifically elects not to utilize telephone redemp-
            tions) and to elect one or more of the additional redemption pro-
            cedures described below. A shareholder may change the instructions
            indicated on his original Account Application, or may request ad-
            ditional redemption options, only by transmitting a written direc-
            tion to the Transfer Agent. Requests to institute or change any of
            the additional redemption procedures will require a signature
            guarantee.
               Redemption proceeds will normally be mailed to the redeeming
            shareholder within seven days or, in the case of wire transfer or
            Fund Link redemptions, sent to the designated bank account within
            one business day. Fund Link redemptions may be received by the
            bank on the second or third business day. In cases where shares
            have recently been purchased by personal check, redemption pro-
            ceeds may be withheld until the check has been collected, which
            may take up to 15 days. To avoid such withholding, investors
            should purchase shares by certified or bank check or by wire
            transfer.
 
 
WRITTEN     To redeem shares in writing (whether or not represented by certif-
REQUESTS    icates), a shareholder must send the following items to the Trans-
            fer Agent, Shareholder Services, Inc., P.O. Box 5866, Denver, Col-
            orado 80217-5866: (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 be-
            low, a guarantee of all signatures on the written request or on
            the share certificate or accompanying stock power, if required, as
            described under "How to Buy Shares--Signature Guarantee"; (3) any
            share certificates issued for any of the shares to be redeemed
            (see "Certificated Shares" below); and (4) any additional docu-
            ments 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 re-
            demption 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 of $50,000
            or less, requested by and payable to all shareholders of record
            for the account, to be sent to the address of record for that ac-
            count. To avoid delay in redemption or transfer, shareholders hav-
            ing any questions about these requirements should contact the
            Transfer Agent in writing or call 1-800-426-0107 before submitting
            a request. Redemption or transfer requests will not be honored un-
            til all required documents in the proper form have been received
            by the Transfer Agent. This redemption option does not apply to
            shares held in broker "street name" accounts.
               If the proceeds of the redemption (i) exceed $50,000, (ii) are
            to be paid to a person other than the record owner, (iii) are to
            be sent to an address other than the address of the account on the
            Transfer Agent's records, or (iv) are to be paid to a corporation,
            partnership, trust or fiduciary, the signature(s) on the redemp-
            tion request and on the certificates, if any, or stock power must
            be guaranteed as described above, except that the Distributor may
            waive the signature guarantee requirement for redemptions up to
            $2,500 by a trustee of a qualified retirement plan, the adminis-
            trator for which has an agreement with the Distributor.

TELEPHONE   The Trust accepts telephone requests for redemption of
REDEMPTIONS uncertificated shares for amounts up to $50,000 within any 7 cal-
            endar day period, except for investors who have specifically de-
            clined telephone redemption privileges on the Account Application
            or elected in writing not to utilize telephone redemptions. The
            proceeds of a telephone redemption will be sent to the record
            shareholder at his record address. Changes in account information
            must be made in a written authorization with a signature guaran-
            tee. See "How to Buy Shares--Signature Guarantee." Telephone re-
            demptions will not be accepted during the 30-day period following
            any change in an account's record address. This redemption option
            does not apply to shares held in broker "street name" accounts.
               By completing an Account Application, an investor agrees that
            the Trust, the Distributor and the Transfer Agent shall not be li-
            able for any loss incurred by the investor by reason of the Trust
            accepting unauthorized telephone redemption requests for his ac-
            count if the Trust reasonably believes the instructions to be gen-
            uine. Thus, shareholders risk possible losses in the event of a
            telephone redemption not authorized by them. The Trust may accept
            telephone redemption instructions from any person identifying him-
            self as the owner of an account or the owner's broker where the
            owner has not declined in writing to utilize this service. The
            Trust will employ reasonable procedures to confirm that instruc-
            tions communicated by telephone are genuine, and may be liable for
            any losses due to unauthorized or fraudulent instructions if it
            fails to employ such procedures. The Trust will require a form of
            personal identification prior to acting on a caller's telephone
            instructions, will provide written confirmations of such transac-
            tions and will record telephone instructions.
               A shareholder making a telephone redemption should call the
            Transfer Agent at 800-852-8457 and state (i) the name of the
            shareholder as it appears on the Transfer Agent's records, (ii)
            his account number with the Trust, (iii) the amount to be with-
            drawn and (iv) the name of the person requesting the redemption.
            Usually the proceeds are sent to the investor on the next Trust
            business day after the redemption is effected, provided the re-
            demption request is received prior to the close of regular trading
            (normally 4:00 p.m. Eastern time) on the Exchange that day. If the
            redemption request is received after the close of the Exchange,
            the redemption is effected on the following Trust business day at
            that day's net asset value and the proceeds are usually sent to
            the investor on the second following Trust business day. The Trust
            reserves the right to terminate or modify the telephone redemption
            service at any time. During times of severe disruptions in the se-
            curities markets, the volume of calls may make it difficult to re-
            deem by telephone, in which case a shareholder may wish to send a
            written request for redemption as described under "Written Re-
            quests" above. Telephone communications may be recorded by the
            Distributor or the Transfer Agent.
 
 
FUND LINK   If a shareholder has established Fund Link, the shareholder may
REDEMPTIONS redeem shares by telephone and have the redemption proceeds sent
            to a designated account at a financial institution. Fund Link is
            normally established within 45 days of receipt of a Fund Link Ap-
            plication by the Transfer Agent. To use Fund Link for redemptions,
            call the Transfer Agent at 800-852-8457. Subject to the limita-
            tions set forth above under "Telephone Redemptions," the Distribu-
            tor, the Trust and the Transfer Agent may rely on instructions by
            any registered owner believed to be genuine and will not be re-
            sponsible to any shareholder for any loss, damage or expense aris-
            ing out of such instructions. Requests received by the Transfer
            Agent prior to the close of regular trading (normally 4:00 p.m.
            Eastern time) on the Exchange on a business day will be processed
            at the net asset value on that day and the proceeds (less any
            CDSC) will normally be sent to the designated bank account on the
            following business day and received by the bank on the second or
            third business day. If the redemption request is received after
            the close of regular trading on the Exchange, the redemption is
            effected on the following business day. Shares purchased by check
            may not be redeemed through Fund Link until such shares have been
            owned (i.e., paid for) for at least 15 days. Fund Link may not be
            used to redeem shares held in certificated form.
               Changes in bank account information must be made by completing
            a new Fund Link Application, signed by all owners of record of the
            account, with all signatures guaranteed. See "How to Buy Shares--
            Signature Guarantee." See "How to Buy Shares--PIMCO Fund Link" for
            information on establishing the Fund Link privilege. The Trust may
            terminate the Fund Link program at any time without notice to
            shareholders. This redemption option does not apply to shares held
            in broker "street name" accounts.

EXPEDITED   If a shareholder has given authorization for expedited wire re-
WIRE        demption, shares can be redeemed and the proceeds sent by federal
TRANSFER    wire transfer to a single previously designated bank account. Re-
REDEMPTIONS quests received by the Trust prior to the close of the Exchange
            will result in shares being redeemed that day at the next deter-
            mined net asset value (less any CDSC) and normally the proceeds
            being sent to the designated bank account the following business
            day. The bank must be a member of the Federal Reserve wire system.
            Delivery of the proceeds of a wire redemption request may be de-
            layed by the Trust for up to 7 days if the Distributor deems it
            appropriate under then current market conditions. Once authoriza-
            tion is on file, the Trust will honor requests by any person iden-
            tifying himself as the owner of an account or the owner's broker
            by telephone at 800-852-8457 or by written instructions. The Trust
            cannot be responsible for the efficiency of the Federal Reserve
            wire system or the shareholder's bank. The Trust does not cur-
            rently charge for wire transfers. The shareholder is responsible
            for any charges imposed by the shareholder's bank. The minimum
            amount that may be wired is $2,500. The Trust reserves the right
            to change this minimum or to terminate the wire redemption privi-
            lege. Shares purchased by check may not be redeemed by wire trans-
            fer until such shares have been owned (i.e., paid for) for at
            least 15 days. Expedited wire transfer redemptions may be autho-
            rized by completing a form available from the Distributor. Wire
            redemptions may not be used to redeem shares in certificated form.
            To change the name of the single bank account designated to re-
            ceive wire redemption proceeds, it is necessary to send a written
            request with signatures guaranteed to PIMCO Funds Distribution
            Company, P.O. Box 5866, Denver, CO 80217-5866. See "How to Buy
            Shares-- Signature Guarantee." This redemption option does not ap-
            ply to shares held in broker "street name" accounts.
 
 
CERTIFICAT- To redeem shares for which certificates have been issued, the cer-
ED SHARES   tificates must be mailed to or deposited with the Trust, duly en-
            dorsed or accompanied by a duly endorsed stock power or by a writ-
            ten request for redemption. Signatures must be guaranteed as de-
            scribed under "How to Buy Shares--Signature Guarantee." Further
            documentation may be requested from institutions or fiduciary ac-
            counts, such as corporations, custodians (e.g., under the Uniform
            Gifts to Minors Act), executors, administrators, trustees or
            guardians ("institutional account owners"). The redemption request
            and stock power must be signed exactly as the account is regis-
            tered, including indication of any special capacity of the regis-
            tered owner.
 
 
AUTOMATIC   An investor who owns or buys shares of a Fund having a net asset
WITHDRAWAL  value of $10,000 or more may open an Automatic Withdrawal Plan and
PLAN        have a designated sum of money (not less than $100 per Fund) paid
            monthly (or quarterly) to the investor or another person. Such a
            plan may be established by completing the appropriate section of
            the Account Application or you may obtain an Automatic Withdrawal
            Plan Application from the Distributor or your broker. If an Auto-
            matic Withdrawal Plan is set up after the account is established
            providing for payment to a person other than the record share-
            holder or to an address other than the address of record, a signa-
            ture guarantee is required. See "How to Buy Shares--Signature
            Guarantee." Class A, Class B and Class C shares of any Fund are
            deposited in a plan account and all distributions are reinvested
            in additional shares of the particular class of the Fund at net
            asset value. Shares in a plan account are then redeemed at net as-
            set value (less any applicable CDSC) to make each withdrawal pay-
            ment. Any applicable CDSC may be waived for certain redemptions
            under an Automatic Withdrawal Plan. See "Alternative Purchase Ar-
            rangements--Waiver of Contingent Deferred Sales Charges."
               Redemptions for the purpose of withdrawals are ordinarily made
            on the business day preceding the day of payment at that day's
            closing net asset value and checks are mailed on the day of pay-
            ment selected by the shareholder. The Transfer Agent may acceler-
            ate the redemption and check mailing date by one day to avoid
            weekend delays. Payment will be made to any person the investor
            designates; however, if the shares are registered in the name of a
            trustee or other fiduciary, payment will be made only to the fidu-
            ciary, except in the case of a profit-sharing or pension plan
            where payment will be made to the designee. As withdrawal payments
            may include a return of principal, they cannot be considered a
            guaranteed annuity or actual yield of income to the investor. The
            redemption of shares in connection with an Automatic Withdrawal
            Plan may result in a gain or loss for tax purposes. Continued
            withdrawals in excess of income will reduce and possibly exhaust
            invested principal, especially in the event of a market decline.

            Automatic Withdrawal Plan concurrently with purchases of addi-
            tional shares of the Fund would be disadvantageous to the investor
            because of the CDSC that may become payable on such withdrawals in
            the case of Class A, Class B or Class C shares and because of the
            initial sales charge in the case of Class A shares. For this rea-
            son, the minimum investment accepted for a Fund while an Automatic
            Withdrawal Plan is in effect for that Fund is $1,000, and an in-
            vestor may not maintain a plan for the accumulation of shares of
            the Fund (other than through reinvestment of distributions) and an
            Automatic Withdrawal Plan at the same time. The Trust or the Dis-
            tributor may terminate or change the terms of the Automatic With-
            drawal Plan at any time.
               Because the Automatic Withdrawal Plan may involve invasion of
            capital, investors should consider carefully with their own finan-
            cial advisers whether the plan and the specified amounts to be
            withdrawn are appropriate in their circumstances. The Trust and
            the Distributor make no recommendations or representations in this
            regard.
 
            Distributor and Distribution and Servicing Plans
 
            PIMCO Funds Distribution Company (the "Distributor"), a wholly
            owned subsidiary of the Advisor, is the principal underwriter of
            the Trust's shares and in that connection makes distribution and
            servicing payments to participating brokers and servicing payments
            to certain banks and other financial intermediaries in connection
            with the sale of Class B and Class C shares and servicing payments
            to participating brokers, certain banks and other financial inter-
            mediaries in connection with the sale of Class A shares. In the
            case of Class A shares, these parties are also compensated based
            on the amount of the front-end sales charge reallowed by the Dis-
            tributor, except in cases where Class A shares are sold without a
            front-end sales charge. In the case of Class B shares, participat-
            ing brokers and other financial intermediaries are compensated by
            an advance of a sales commission by the Distributor. In the case
            of Class C shares, part or all of the first year's distribution
            and servicing fee is generally paid at the time of sale. Pursuant
            to a Distribution Agreement with the Trust, with respect to each
            Fund's Class A, Class B and Class C shares, the Distributor bears
            various other promotional and sales related expenses, including
            the cost of printing and mailing prospectuses to persons other
            than current shareholders.
 
            CLASS A SERVICING FEES: As compensation for services rendered and
            expenses borne by the Distributor in connection with personal
            services rendered to Class A shareholders of the Trust and the
            maintenance of Class A shareholder accounts, the Trust pays the
            Distributor servicing fees up to the annual rate of .25% (calcu-
            lated as a percentage of each Fund's average daily net assets at-
            tributable to Class A shares).
 
            CLASS B AND CLASS C DISTRIBUTION AND SERVICING FEES: As compensa-
            tion for services rendered and expenses borne by the Distributor
            in connection with the distribution of Class B and Class C shares
            of the Trust, and in connection with personal services rendered to
            Class B and Class C shareholders of the Trust and the maintenance
            of Class B and Class C shareholder accounts, the Trust pays the
            Distributor servicing and distribution fees up to the annual rates
            set forth below (calculated as a percentage of each Fund's average
            daily net assets attributable to Class B and Class C shares,
            respectively):

               The Class A servicing fees and Class B and Class C distribution

            1940, as amended (the "1940 Act"), and are of the type known as
            "compensation" plans. This means that, although the Trustees of
            the Trust are expected to take into account the expenses of the
            Distributor and its predecessors in their periodic review of the
            Distribution and Servicing Plans, the fees are payable to compen-
            sate the Distributor for services rendered even if the amount paid
            exceeds the Distributor's expenses.
               The distribution fee applicable to Class B and Class C shares
            may be spent by the Distributor on any activities or expenses pri-
            marily intended to result in the sale of Class B or Class C
            shares, respectively, including compensation to, and expenses (in-
            cluding overhead and telephone expenses) of, financial consultants
            or other employees of the Distributor or of participating or in-
            troducing brokers who engage in distribution of Class B or Class C
            shares, printing of prospectuses and reports for other than exist-
            ing Class B or Class C shareholders, advertising, and preparation,
            printing and distribution of sales literature. The servicing fee,
            applicable to Class A, Class B and Class C shares of the Trust,
            may be spent by the Distributor on personal services rendered to
            shareholders of the Trust and the maintenance of shareholder ac-
            counts, including compensation to, and expenses (including tele-
            phone and overhead expenses) of, financial consultants or other
            employees of participating or introducing brokers, certain banks
            and other financial intermediaries who aid in the processing of
            purchase or redemption requests or the processing of dividend pay-
            ments, who provide information periodically to shareholders show-
            ing their positions in a Fund's shares, who forward communications
            from the Trust to shareholders, who render ongoing advice concern-
            ing the suitability of particular investment opportunities offered
            by the Trust in light of the shareholders' needs, who respond to
            inquiries from shareholders relating to such services, or who
            train personnel in the provision of such services. Distribution
            and servicing fees may also be spent on interest relating to
            unreimbursed distribution or servicing expenses from prior years.
               Many of the Distributor's sales and servicing efforts involve
            the Trust as a whole, so that fees paid by Class A, Class B or
            Class C shares of any Fund may indirectly support sales and ser-
            vicing efforts relating to the other Funds' shares of the same
            class. In reporting its expenses to the Trustees, the Distributor
            itemizes expenses that relate to the distribution and/or servicing
            of a single Fund's shares, and allocates other expenses among the
            Funds based on their relative net assets. Expenses allocated to
            each Fund are further allocated among its classes of shares annu-
            ally based on the relative sales of each class, except for any ex-
            penses that relate only to the sale or servicing of a single
            class. The Distributor may make payments to brokers (and with re-
            spect to servicing fees only, to certain banks and other financial
            intermediaries) of up to the following percentages annually of the
            average daily net assets attributable to shares in the accounts of
            their customers or clients:

            3. Payable only with respect to shares outstanding for one year or

               The Distributor may from time to time pay additional cash bo-
            nuses or other incentives to selected participating brokers in
            connection with the sale or servicing of Class A, Class B and
            Class C shares of the Funds. On some occasions, such bonuses or
            incentives may be conditioned upon the sale of a specified minimum
            dollar amount of the
                                                      March 5, 1997 Prospectus

            shares of a Fund and/or all of the Funds together or a particular
            class of shares, during a specific period of time. The Distributor
            currently expects that such additional bonuses or incentives will
            not exceed .50% of the amount of any sale. In its capacity as ad-
            ministrator for the Funds, PIMCO Advisors may pay participating
            brokers and other intermediaries for sub-transfer agency and other
            services.
               If in any year the Distributor's expenses incurred in connec-
            tion with the distribution of Class B and Class C shares and, for
            Class A, Class B and Class C shares, in connection with the ser-
            vicing of shareholders and the maintenance of shareholder ac-
            counts, exceed the distribution and/or servicing fees paid by the
            Trust, the Distributor would recover such excess only if the Dis-
            tribution and Servicing Plan with respect to such class of shares
            continues to be in effect in some later year when the distribution
            and/or servicing fees exceed the Distributor's expenses. The Trust
            is not obligated to repay any unreimbursed expenses that may exist
            at such time, if any, as the relevant Distribution and Servicing
            Plan terminates.
               From time to time, expenses of principal underwriters incurred
            in connection with the sale of Class B and Class C shares of the
            Funds and, in connection with the servicing of Class B and Class C
            shareholders of the Funds and the maintenance of Class B and Class
            C shareholder accounts, may exceed the distribution and servicing
            fees collected by the Distributor. Class B and Class C Distribu-
            tion and Servicing Plans, which are similar to the Trust's current
            Plans, were in effect prior to the date of this Prospectus in re-
            spect of certain series of PIMCO Advisors Funds that were prede-
            cessors of the Funds listed below. The remaining Funds did not of-
            fer Class B or Class C shares prior to the date of this Prospec-
            tus. As of September 30, 1996, such expenses were approximately
            $11,408,000 in excess of payments under the PIMCO Advisors Funds'
            Class B Distribution and Servicing Plan and $2,822,000 in excess
            of payments under the PIMCO Advisors Funds' Class C Distribution
            and Servicing Plan. The allocation of such excess (on a pro rata
            basis) among the predecessors to the Funds listed below as of Sep-
            tember 30, 1996 was a follows:

            each Fund of the Trust will be determined once on each day on
            which the Exchange is open (a "Business Day"), as of the close of
            regular trading (normally 4:00 p.m., Eastern time) on the Ex-
            change. Portfolio securities for which market quotations are read-
            ily available are valued at market value. Fixed income securities
            generally are valued on the basis of quotations obtained from bro-
            kers and dealers or pricing services, which take into account ap-
            propriate factors such as institutional-sized trading in similar
            groups of securities, yield, quality, coupon rate, maturity, type
            of issue, trading characteristics, and other market data. Certain
            fixed income securities for which daily market quotations are not
            readily available may be valued, pursuant to guidelines estab-
            lished

            by the Board of Trustees, with reference to fixed income securi-
            ties whose prices are more readily obtainable and whose durations
            are comparable to the securities being valued. Short-term invest-
            ments having a maturity of 60 days or less are valued at amortized
            cost, when the Board of Trustees determines that amortized cost is
            their fair value. Exchange-traded options, futures and options on
            futures are valued at the settlement price as determined by the
            appropriate clearing corporation. All other securities and assets
            are valued at their fair value as determined in good faith by the
            Trustees or by persons acting at their direction.
               Quotations of foreign securities in foreign currency are con-
            verted to U.S. dollar equivalents using foreign exchange quota-
            tions received from independent dealers. The calculation of the
            net asset value of the International Developed, International,
            Emerging Markets and Precious Metals Funds may not take place con-
            temporaneously with the determination of the prices of certain
            portfolio securities of foreign issuers used in such calculation.
            Further, under the Trust's procedures, the prices of foreign secu-
            rities are determined using information derived from pricing serv-
            ices and other sources. Information that becomes known to the
            Trust or its agents after the time that net asset value is calcu-
            lated on any Business Day may be assessed in determining net asset
            value per share after the time of receipt of the information, but
            will not be used to retroactively adjust the price of the security
            so determined earlier or on a prior day. Events affecting the val-
            ues of portfolio securities that occur between the time their
            prices are determined and 4:00 p.m., Eastern time, may not be re-
            flected in the calculation of net asset value. If events materi-
            ally affecting the value of such securities occur during such pe-
            riod, then these securities may be valued at fair value as deter-
            mined by the Advisor or a Portfolio Manager and approved in good
            faith by the Board of Trustees.
               Each Fund's liabilities are allocated among its classes. The
            total of such liabilities allocated to a class plus that class's
            distribution and/or servicing fees and any other expenses spe-
            cially allocated to that class are then deducted from the class's
            proportionate interest in the Fund's assets, and the resulting
            amount for each class is divided by the number of shares of that
            class outstanding to produce the class's "net asset value" per
            share. Under certain circumstances, the per share net asset value
            of the Class B and Class C shares of the Funds that do not declare
            regular income dividends on a daily basis may be lower than the
            per share net asset value of the Class A shares as a result of the
            daily expense accruals of the distribution fee applicable to the
            Class B and Class C shares. Generally, for Funds that pay income
            dividends, those dividends are expected to differ over time by ap-
            proximately the amount of the expense accrual differential between
            the classes.
 
            Distributions
 
            Shares begin earning dividends on the effective date of purchase,
            which is the date that funds are received by the Trust for the
            purchase of Class A, Class B and Class C shares. Net investment
            income from interest and dividends, if any, will be declared daily
            and paid monthly to shareholders of record of the Tax Exempt Fund
            and declared and paid quarterly to shareholders of record by the
            Equity Income, Renaissance, Value and Balanced Funds. Net
            investment income from interest and dividends, if any, will be
            declared and paid at least annually to shareholders of record by
            the Capital Appreciation, Growth, Mid Cap Growth, Target, Small
            Cap Value, Opportunity, International Developed, International,
            Emerging Markets, Innovation and Precious Metals Funds. Any net
            realized capital gains from the sale of portfolio securities will
            be distributed no less frequently than once annually. Net realized
            short-term capital gains may be paid more frequently.
               All dividends and/or distributions will be paid in the form of
            additional shares of the class of shares of the Fund to which the
            dividends and/or distributions relate or, at the election of the
            shareholder, of another Fund of the Trust as described below, at
            net asset value of such Fund, unless the shareholder elects to re-
            ceive cash (either paid to shareholders directly or credited to
            their account with their participating broker). Dividends paid by
            each Fund with respect to each class of shares are calculated in
            the same manner and at the same time, but dividends on Class B and
            Class C

            shares are expected to be lower than dividends on Class A shares
            as a result of the distribution fee applicable to Class B and
            Class C shares. There are no sales charges on reinvested divi-
            dends.
               Class A, Class B and Class C shareholders of the Trust may
            elect to invest dividends and/or distributions paid by any Fund in
            shares of the same class of any other Fund of the Trust or series
            of PIMCO Funds: Pacific Investment Management Series which offers
            such class of shares at net asset value. The shareholder must have
            an account existing in the Fund or series selected for investment
            with the identical registered name and address and must elect this
            option on the Account Application, on a form provided for that
            purpose or by a telephone request to the Transfer Agent at 800-
            852-8457. For further information on this option, contact your
            broker or call the Distributor at 800-426-0107.
 
            Taxes
 
            Each Fund intends to qualify as a regulated investment company an-
            nually and to elect to be treated as a regulated investment com-
            pany under the Internal Revenue Code of 1986, as amended (the
            "Code"). As such, a Fund generally will not pay federal income tax
            on the income and gains it pays as dividends to its shareholders.
            In order to avoid a 4% federal excise tax, each Fund intends to
            distribute each year substantially all of its net income and
            gains.
               Shareholders subject to U.S. federal income tax will be subject
            to tax on dividends received from a Fund, regardless of whether
            received in cash or reinvested in additional shares. Distributions
            received by tax-exempt shareholders will not be subject to federal
            income tax to the extent permitted under applicable tax law. All
            shareholders must treat dividends, other than capital gain divi-
            dends, exempt-interest dividends and dividends that represent a
            return of capital to shareholders, as ordinary income. In particu-
            lar, distributions derived from short-term gains will be treated
            as ordinary income. Dividends designated by a Fund as capital gain
            dividends derived from the Fund's net capital gains (that is, the
            excess of its net long-term capital gains over its net short-term
            capital losses) are taxable to shareholders as long-term capital
            gain except as provided by an applicable tax exemption. Any dis-
            tributions that are not from a Fund's net investment income or net
            capital gain may be characterized as a return of capital to share-
            holders or, in some cases, as capital gain. Certain dividends de-
            clared in October, November or December of a calendar year are
            taxable to shareholders (who otherwise are subject to tax on divi-
            dends) as though received on December 31 of that year if paid to
            shareholders during January of the following calendar year. Each
            Fund will advise shareholders annually of the amount and nature of
            the dividends paid to them.
               Dividends paid to shareholders by the Tax Exempt Fund which are
            derived from interest on Tax Exempt Bonds are expected to be des-
            ignated by the Fund as "exempt-interest dividends," and sharehold-
            ers may exclude such dividends from gross income for federal in-
            come tax purposes. However, if a shareholder receives social secu-
            rity or railroad retirement benefits, the shareholder may be taxed
            on a portion of those benefits as a result of receiving tax-exempt
            income. In addition, certain exempt-interest dividends could, as
            discussed below, cause certain shareholders to become subject to
            the alternative minimum tax and may increase the alternative mini-
            mum tax liability of shareholders already subject to this tax.
            Other distributions from the Tax Exempt Fund may constitute tax-
            able income, and any gain realized on a redemption of shares will
            be taxable gain, subject to any applicable tax exemption for which
            an investor may qualify.
               Dividends derived from interest on certain U.S. Government se-
            curities may be exempt from state and local taxes, although inter-
            est on mortgage-backed U.S. Government securities may not be so
            exempt. The distributions of "exempt-interest dividends" paid by
            the Tax Exempt Fund may be exempt from state and local taxation
            when received by a shareholder to the extent that they are derived
            from interest on Tax Exempt Bonds issued by the state or political
            subdivision in which such shareholder resides. The federal exemp-
            tion for "exempt-interest dividends" attributable to Tax Exempt
            Bonds does not necessarily result in exemption of such dividends
            from income for the purpose of state and local taxes. The Trust
            will report annually on a state-by-state basis the source of in-
            come the Tax Exempt Fund receives on Tax Exempt Bonds that was
            paid out as dividends during the preceding year.

               The Code also provides that exempt-interest dividends allocable
            to interest received from "private activity bonds" issued after
            August 7, 1986 are an item of tax preference for individual and
            corporate alternative minimum tax at the applicable rate for indi-
            viduals and corporations. Therefore, if the Tax Exempt Fund in-
            vests in such private activity bonds, certain of its shareholders
            may become subject to the alternative minimum tax on that part of
            its distributions to them that are derived from interest income on
            such bonds, and certain shareholders already subject to such tax
            may have increased liability therefor. However, it is the present
            policy of the Tax Exempt Fund to invest no more than 20% of its
            assets in such bonds. Other provisions of the Code affect the tax
            treatment of distributions from the Tax Exempt Fund for corpora-
            tions, casualty insurance companies, and financial institutions.
            In particular, under the Code, for corporations, alternative mini-
            mum taxable income will be increased by a percentage of the amount
            by which the corporation's "adjusted current earnings" (which in-
            cludes various items of tax exempt income) exceeds the amount oth-
            erwise determined to be alternative minimum taxable income. Ac-
            cordingly, an investment in the Tax Exempt Fund may cause share-
            holders to be subject to (or result in an increased liability un-
            der) the alternative minimum tax.
               Current federal tax law requires the holder of a U.S. Treasury
            or other fixed income zero-coupon security to accrue as income
            each year a portion of the discount at which the security was pur-
            chased, even though the holder receives no interest payment in
            cash on the security during the year. In addition, pay-in-kind se-
            curities will give rise to income which is required to be distrib-
            uted and is taxable even though the Fund holding the security re-
            ceives no interest payment in cash on the security during the
            year. Also, a portion of the yield on certain high yield securi-
            ties (including certain pay-in-kind securities) issued after July
            10, 1987 may be treated as dividends. Accordingly, each Fund that
            holds the foregoing kinds of securities may be required to pay out
            as an income distribution each year an amount which is greater
            than the total amount of cash interest the Fund actually received.
            Such distributions may be made from the cash assets of the Fund or
            by liquidation of portfolio securities, if necessary. The Fund may
            realize gains or losses from such liquidations. In the event the
            Fund realizes net capital gains from such transactions, its share-
            holders may receive a larger capital gain distribution, if any,
            than they would in the absence of such transactions.
               Taxable shareholders should note that the timing of their in-
            vestment or redemptions could have undesirable tax consequences.
            If shares are purchased on or just before the record date of a
            dividend, taxable shareholders will pay full price for the shares
            and may receive a portion of their investment back as a taxable
            distribution. If shares are redeemed before payment of an exempt-
            interest dividend, shareholders may realize a taxable capital
            gain, whereas by waiting and receiving the exempt-interest divi-
            dend, a portion of their share value would have been received in
            the form of tax-free income.
               The preceding discussion relates only to federal income tax;
            the consequences under other tax laws may differ. Shareholders
            should consult their tax advisers as to the possible application
            of state and local income tax laws to Trust dividends and capital
            gain distributions. For additional information relating to the tax
            aspects of investing in a Fund, see the Statement of Additional
            Information.
 
            Management of the Trust
 
            The business affairs of the Trust are managed under the direction
            of the Board of Trustees. Information about the Trustees and the
            Trust's executive officers may be found in the Statement of Addi-

INVESTMENT  PIMCO ADVISORS serves as investment adviser to the Funds pursuant
ADVISOR     to an investment advisory agreement with the Trust. PIMCO Advisors
            is a Delaware limited partnership organized in 1987. PIMCO Advi-
            sors provides investment management and advisory services to pri-
            vate accounts of institutional and individual clients and to mu-

            its subsidiary partnerships as of November 30, 1996 were approxi-
            mately $111 billion. A portion of the units of the limited partner
            interest in PIMCO Advisors is traded publicly on the

            Exchange. The general partner of PIMCO Advisors is PIMCO Partners,
            G.P. Pacific Mutual Life Insurance Company and its affiliates hold
            a substantial interest in PIMCO Advisors through direct or
            indirect ownership of units of PIMCO Advisors, and indirectly hold
            a majority interest in PIMCO Partners, G.P., with the remainder
            held indirectly by a group composed of the Managing Directors of
            Pacific Investment Management. PIMCO Advisors is governed by an
            Operating Board and an Equity Board, which exercise substantially
            all of the governance powers of the general partner and serve as
            the functional equivalent of a board of directors. Pacific
            Investment Management and the Managing Directors, because of their
            ability to designate a majority of the Members of the Operating
            Board, could be said to control PIMCO Advisors, although they
            disclaim such authority. PIMCO Advisors' address is 800 Newport
            Center Drive, Suite 100, Newport Beach, California 92660. PIMCO
            Advisors is registered as an investment adviser with the
            Securities and Exchange Commission. PIMCO Advisors currently has
            six subsidiary partnerships, the following five of which manage
            one or more of the Funds: Blairlogie, Cadence, Columbus Circle,
            NFJ and Pacific Investment Management.
               Under the investment advisory agreement, PIMCO Advisors, sub-
            ject to the supervision of the Board of Trustees, is responsible
            for providing advice and guidance with respect to the Funds and
            for managing, either directly or through others selected by the
            Advisor, the investment of the Funds. PIMCO Advisors also fur-
            nishes to the Board of Trustees periodic reports on the investment
            performance of each Fund.
 
PORTFOLIO   Pursuant to portfolio management agreements, PIMCO Advisors em-
MANAGERS    ploys Portfolio Managers to provide investment advisory services
            to all of the Funds. With the exception of Van Eck (which manages
            the Precious Metals Fund), each Portfolio Manager is an affiliate
            of PIMCO Advisors. PIMCO Advisors compensates the Portfolio Manag-
            ers from its advisory fee (not from the Trust). Under these agree-
            ments, a Portfolio Manager has full investment discretion and
            makes all determinations with respect to the investment of a
            Fund's assets, or, for the Balanced Fund, with respect to the por-
            tion of the Fund's assets allocated to the Portfolio Manager for
            investment, and makes all determinations respecting the purchase
            and sale of a Fund's securities and other investments.
 
            COLUMBUS CIRCLE manages the Renaissance Fund, the Growth Fund, the
            Target Fund, the Opportunity Fund, the Innovation Fund and the Tax
            Exempt Fund (the "Columbus Circle Funds"). Columbus Circle is an
            investment management firm organized as a general partnership. Co-
            lumbus Circle has two partners: PIMCO Advisors as the supervisory
            partner, and Columbus Circle Investors Management, Inc. as the
            managing partner. Columbus Circle Investors Division of Thomson
            Advisory Group L.P. ("TAG"), the predecessor investment adviser to
            Columbus Circle, commenced operations in 1975. Accounts managed by
            Columbus Circle had combined assets as of November 30, 1996 of ap-
            proximately $14 billion. Columbus Circle's address is Metro Cen-
            ter, One Station Place, 8th Floor, Stamford, Connecticut 06902.
            Columbus Circle is registered as an investment adviser with the
            Securities and Exchange Commission.
               At the center of Columbus Circle's equity investment strategy
            is its theory of Positive Momentum & Positive Surprise. This the-
            ory asserts that a good company doing better than generally ex-
            pected will experience a rise in its stock price, and conversely,
            a company falling short of expectations will experience a drop in
            its stock price. Based on this theory, Columbus Circle attempts to
            manage the Columbus Circle Funds (except the Tax Exempt Fund) with
            a view to investing in growing companies that are surprising the
            market with business results that are better than anticipated. The
            Trust has been informed that investment decisions made by Columbus
            Circle with respect to the Columbus Circle Funds are made by a
            committee rather than by a single person acting as portfolio man-
            ager. No person is primarily responsible for making recommenda-
            tions to that committee.
 
            CADENCE manages the Capital Appreciation Fund, the Mid Cap Growth
            Fund and a portion of the Common Stock Segment of the Balanced

PORTFOLIO   Pursuant to the portfolio management agreements, a Portfolio Man-
TRANSAC-    ager places orders for the purchase and sale of portfolio invest-
TIONS       ments for a Fund's accounts with brokers or dealers selected by it
            in its discretion. In effecting purchases and sales of portfolio
            securities for the accounts of the Funds, the Portfolio Managers
            will seek the best price and execution of the Fund's orders. In
            doing so, a Fund may pay higher commission rates than the lowest
            available when the Portfolio Manager believes it is reasonable to
            do so in light of the value of the brokerage and research services
            provided by the broker effecting the transaction. The Portfolio
            Managers also may consider sales of shares of the Trust as a fac-
            tor in the selection of broker-dealers to execute portfolio trans-
            actions for the Trust.
               Some securities considered for investment by the Funds may also
            be appropriate for other clients served by the Portfolio Managers.
            If a purchase or sale of securities consistent with the investment
            policies of a Fund and one or more of these clients served by a
            Portfolio Manager is considered at or about the same time, trans-
            actions in such securities will be allocated among the Fund and
            clients in a manner deemed fair and reasonable by the Portfolio
            Manager.

            cumstances, be held liable for the obligations of the Trust. How-
            ever, the Second Amended and Restated Agreement and Declaration of
            Trust (the "Declaration of Trust") of the Trust disclaims share-
            holder liability for acts or obligations of the Trust and requires
            that notice of such disclaimer be given in each agreement, obliga-
            tion or instrument entered into or executed by the Trust or the
            Trustees. The Declaration of Trust also provides for indemnifica-
            tion out of a Fund's property for all loss and expense of any
            shareholder of that Fund held liable on account of being or having
            been a shareholder. Thus, the risk of a shareholder incurring fi-
            nancial loss on account of shareholder liability is limited to
            circumstances in which such disclaimer is inoperative or the Fund
            of which he or she is or was a shareholder is unable to meet its
            obligations, and thus should be considered remote.
 
MULTIPLE
CLASSESOF   In addition to Class A shares, Class B shares and Class C shares,
SHARES      certain Funds also offer Institutional and Administrative Class
            shares through a separate prospectus, as described under "Alterna-
            tive Purchase Arrangements." This Prospectus relates only to Class
            A shares, Class B shares and Class C shares of the Funds.
               Class A, Class B and Class C shares of each Fund represent in-
            terests in the assets of that Fund and have identical dividend,
            liquidation and other rights and the same terms and conditions ex-
            cept that expenses related to the distribution and shareholder
            servicing of Class A, Class B and Class C shares are borne solely
            by such class and each class may, at the Trustees' discretion,
            also pay a different share of other expenses, not including advi-
            sory or custodial fees or other expenses related to the management
            of the Trust's assets, if these expenses are actually incurred in
            a different amount by that class, or if the class receives serv-
            ices of a different kind or to a different degree than the other
            classes. All other expenses are allocated to each class on the ba-
            sis of the net asset value of that class in relation to the net
            asset value of the particular Fund.
 
VOTING      Each class of shares of each Fund has identical voting rights ex-
            cept that each class of shares has exclusive voting rights on any
            matter submitted to shareholders that relates solely to that
            class, and has separate voting rights on any matter submitted to
            shareholders in which the interests of one class differ from the
            interests of any other class. Each class of shares has exclusive
            voting rights with respect to matters pertaining to any Distribu-
            tion and Servicing Plan applicable to that class. These shares are
            entitled to vote at meetings of shareholders. Matters submitted to
            shareholder vote must be approved by each Fund separately except
            (i) when required by the 1940 Act shares shall be voted together
            and (ii) when the Trustees have determined that the matter does
            not affect all Funds, then only shareholders of the Fund or Funds
            affected shall be entitled to vote on the matter. All classes of
            shares of a Fund will vote together, except with respect to a Dis-
            tribution and Servicing Plan applicable to a class of shares or
            when a class vote is required as specified above or otherwise by
            the 1940 Act. Shares are freely transferable, are entitled to div-
            idends as declared by the Trustees and, in liquidation of the
            Trust, are entitled to receive the net assets of their Fund, but
            not of the other Funds. The Trust does not generally hold annual
            meetings of shareholders and will do so only when required by law.
            Shareholders may remove Trustees from office by votes cast in per-
            son or by proxy at a meeting of shareholders or by written con-
            sent. Such a meeting will be called at the written request of the
            holders of 10% of the Trust's outstanding shares.
               Shares entitle their holders to one vote per share (with pro-
            portionate voting for fractional shares). As of December 17, 1996,
            the following were shareholders of record of at least 25% of the
            outstanding voting securities of the indicated Fund: Pacific Mu-
            tual Life Insurance Company (Newport Beach, California) with re-
            spect to the Diversified
                                                      March 5, 1997 Prospectus
                                                                              65

            Low P/E Fund (the predecessor of the Value Fund); and Charles
            Schwab & Co., Inc. (San Francisco, California) with respect to the
            Emerging Markets Fund. To the extent such shareholders are also
            the beneficial owners of those shares, they may be deemed to con-
            trol (as that term is defined in the 1940 Act) the relevant Fund.
 
            Mailings to Shareholders
 
            To reduce the volume of mail shareholders receive, it is antici-
            pated that only one copy of most Trust reports, such as the
            Trust's annual report, will be mailed to a shareholder's household
            (same surname, same address). A shareholder may call 800-227-7337
            if additional shareholder reports are desired.
