     The Fund seeks to achieve its investment objective by normally investing at
least 65% of its assets in  securities of companies principally engaged in the
design, manufacture or sale of new, creative or different, or "innovative,"
products or services used for or in connection with health care or medicine.
These companies may include, for example, pharmaceutical companies, companies
involved in biotechnology, medical diagnostic, biochemical or other health care
research and development, companies involved in the operation of health care
facilities, and other companies involved in the design, manufacture or sale of
health care-related products or services such as medical, dental and optical
products, hardware or services.  Although the Fund emphasizes companies which
utilize health care technologies, it is not required to invest exclusively in a
particular business sector or industry, and at any time may not be invested in
any of the industry sectors listed above.

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

     Although the Fund invests principally in common stocks, the Fund may also
invest in other types of equity securities, including preferred stocks and
convertible securities.  The Fund may invest up to 15% of its assets in foreign
securities, usually in the form of American Depository Receipts.

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

</TABLE>

                  (1) Due to the 12b-1 distribution fee imposed on Class B and
                      Class C shares, a Class B or Class C shareholders may,
                      depending upon the length of time the shares are held, pay
                      more than the economic equivalent of the maximum front-end
                      sales charges permitted by relevant rules of the National
                      Association of Securities Dealers, Inc.
                  (2) Other Expenses reflects a 0.50% Administrative Fee paid by
                      the class, which is subject to a reduction of 0.05% on
                      average daily net assets attributable in the aggregate to
                      the Fund's Class A, B and C shares in excess of $2.5
                      billion, and [0.04%] representing the Fund's
                      organizational expenses as attributed to the class
                      ("Organizational Expenses").
                  (3) Net Expenses reflects the effects of a contractual
                      agreement by PIMCO Advisors to waive, reduce or reimburse
                      its Administrative Fee for each class in an amount that,
                      in essence, is equal to the Fund's Organizational Expenses
                      attributed to the class. Because the Organizational
                      Expenses will all be accounted for in the Fund's initial
                      fiscal year, the Fund's reasonable expectation is that the
                      relevant conditions will not continue after the Fund's
                      fiscal year ending June 30, 2001.

                  Examples. The Examples are intended to help you compare the
                  cost of investing in Class A, B or C shares of the Fund with
                  the costs of investing in other mutual funds. The Examples
                  assume that you invest $10,000 in the noted class of shares
                  for the time periods indicated, your investment has a 5%
                  return each year, the reinvestment of all dividends and
                  distributions, and the Fund's operating expenses remain the
                  same. Although your actual costs may be higher or lower, the
                  Examples show what your costs would be based on these
                  assumptions./(1)/

     The Fund seeks to achieve its investment objective by normally investing at
least 65% of its assets in common stocks of companies that derive at least 50%
of their revenues, expenses or profits from the research, design, development,
manufacturing or distribution of new, creative or different, or "innovative,"
products, processes or services for use with Internet- or Internet-related
businesses. Some examples of these companies may include, for example, providers
of broad-band Internet access, web site content, Internet software and
electronic commerce. Although the Fund emphasizes Internet-related companies, it
is not required to invest exclusively in a particular business sector or
industry, and at any time may not be invested in any of the industry sectors
listed above.

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

     Although the Fund invests principally in common stocks, the Fund may also
invest in other types of equity securities, including preferred stocks and
convertible securities. The Fund may invest up to 15% of its assets in foreign
securities, usually in the form of American Depository Receipts.

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

     The Fund seeks to achieve its investment objective by normally investing at
least 65% of its assets in common stocks of technology and technology-related
companies with market capitalizations of between $100 million and $2 billion at
the time of investment. The Fund identifies its investment universe of
technology-related companies primarily by reference to classifications made by
independent firms, such as Standard & Poor's (for example, companies classified
as "Information Technology" companies), and by identifying companies that
derive a substantial portion of their revenues from the manufacture, sale and/or
service of technological products. Although the Fund emphasizes companies which
utilize technologies, it is not required to invest exclusively in a particular
business sector or industry.

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

     Although the Fund invests principally in common stocks, the Fund may also
invest in other types of equity securities, including preferred stocks and
convertible securities. The Fund may invest up to 15% of its assets in foreign
securities, usually in the form of American Depository Receipts.

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

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

                  (1) Imposed only in certain circumstances where Class A shares
                      are purchased without a front-end sales charge at the time
                      of purchase.
                  (2) The maximum CDSC is imposed on shares redeemed in the
                      first year. For shares held longer than one year, the CDSC
                      declines according to the schedule set forth under

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

                      depending upon the length of time the shares are held, pay
                      more than the economic equivalent of the maximum front-end
                      sales charges permitted by relevant rules of the National
                      Association of Securities Dealers, Inc.
                  (2) Other Expenses reflects a 0.50% Administrative Fee paid by
                      the class, which is subject to a reduction of 0.05% on
                      average daily net assets attributable in the aggregate to
                      the Fund's Class A, B and C shares in excess of $2.5
                      billion, and [0.04%] representing the Fund's
                      organizational expenses as attributed to the class
                      ("Organizational Expenses").
                  (3) Net Expenses reflects the effects of a contractual
                      agreement by PIMCO Advisors to waive, reduce or reimburse
                      its Administrative Fee for each class in an amount that,
                      in essence, is equal to the Fund's Organizational Expenses
                      attributed to the class. Because the Organizational
                      Expenses will all be accounted for in the Fund's initial
                      fiscal year, the Fund's reasonable expectation is that the
                      relevant conditions will not continue after the Fund's
                      fiscal year ending June 30, 2001.

                  Examples. The Examples are intended to help you compare the
                  cost of investing in Class A, B or C shares of the Fund with
                  the costs of investing in other mutual funds. The Examples
                  assume that you invest $10,000 in the noted class of shares
                  for the time periods indicated, your investment has a 5%
                  return each year, the reinvestment of all dividends and
                  distributions, and the Fund's operating expenses remain the
                  same. Although your actual costs may be higher or lower, the
                  Examples show what your costs would be based on these
                  assumptions./(1)/

     The Fund seeks to achieve its investment objective by normally investing at
least 65% of its assets in common stocks of companies principally engaged in the
development, manufacture or sale of new, creative or different, or "innovative,"
communications services or communications equipment. These companies may
include, for example, companies that provide traditional local and long-distance
telephone service or equipment, companies that provide cellular, paging, local
and wide area product networks or equipment, companies that provide satellite,
microwave and cable television or equipment, and companies involved in new
technologies such as fiber optics, semiconductors and data transmission.
Although the Fund emphasizes telecommunications-related companies, it is not
required to invest exclusively in a particular business sector or industry, and
at any time may not be invested in any of the industry sectors listed above.

                       pay more than the economic equivalent of the maximum
                       front-end sales charges permitted by relevant rules of
                       the National Association of Securities Dealers, Inc.

                   (2) Other Expenses reflects a 0.50% Administrative Fee paid
                       by the class, which is subject to a reduction of 0.05% on
                       average daily net assets attributable in the aggregate to
                       the Fund's Class A, B and C shares in excess of $2.5
                       billion, and [0.04%] representing the Fund's
                       organizational expenses as attributed to the class
                       ("Organizational Expenses").

                   (3) Net Expenses reflects the effects of a contractual
                       agreement by PIMCO Advisors to waive, reduce or reimburse
                       its Administrative Fee for each class in an amount that,
                       in essence, is equal to the Fund's Organizational
                       Expenses attributed to the class. Because the
                       Organizational Expenses will all be accounted for in the
                       Fund's initial fiscal year, the Fund's reasonable
                       expectation is that the relevant conditions will not
                       continue after the Fund's fiscal year ending June 30,
                       2001.

                   Examples. The Examples are intended to help you compare the
                   cost of investing in Class A, B or C shares of the Fund with
                   the costs of investing in other mutual funds. The Examples
                   assume that you invest $10,000 in the noted class of shares
                   for the time periods indicated, your investment has a 5%
                   return each year, the reinvestment of all dividends and
                   distributions, and the Fund's operating expenses remain the
                   same. Although your actual costs may be higher or lower, the
                   Examples show what your costs would be based on these
                   assumptions./(1)/

     The Fund seeks to achieve its investment objective by normally investing at
least 65% of its assets in common stocks of companies principally engaged in the
development, manufacture or sale of new, creative or different, or "innovative,"
electronics products and services.  These companies may include, for example,
companies engaged in the development, manufacture, sale or service of electronic
components, equipment vendors to electronics manufacturers, electronic component
distributors, electronic instruments and systems vendors, and companies that
provide electronics-related services.  Although the Fund emphasizes companies in
the electronics industry, it is not required to invest exclusively in a
particular business sector or industry, and at any time may not be invested in
any of the types of companies listed above.

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

     Although the Fund invests principally in common stocks, the Fund may also
invest in other types of equity securities, including preferred stocks and
convertible securities.   The Fund may invest up to 15% of its assets in foreign
securities, usually in the form of American Depository Receipts.

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

                 could adversely affect its net asset value, yield and total

     The Fund seeks to achieve its investment objective by normally investing at
least 65% of its assets in an international portfolio of common stocks and other
equity securities of companies located in Asia.  The Fund will primarily invest
in securities of companies located in the Far East, including Australia, China,
Hong Kong, Japan, Indonesia, India, Malaysia, New Zealand, the Philippines,
Singapore, South Korea, Taiwan and Thailand, although the Fund will not
necessarily be invested in all of these countries at any time.  The Fund may
also invest in securities of foreign issuers traded on U.S. securities markets,
but will normally not invest in U.S. issuers.  However, the Fund has no
prescribed limits on geographic asset distribution and may invest in any foreign
securities market in the world.  The Fund invests most of its assets in foreign
securities which trade in currencies other than the U.S. dollar and may invest
directly in foreign currencies.

     The portfolio manager selects securities for the Fund using the Sub-
Adviser's "Growth at a Reasonable Price" (GARP) investment style. The GARP style
uses a research-driven "bottom-up" approach that seeks to identify companies
with above-average long-term growth prospects and attractive valuations and that
possess a sustainable competitive advantage, such as superior or innovative
products, personnel and distribution systems. In selecting stocks, the portfolio
manager analyzes a broad range of company fundamentals, such as long-term growth
prospects, price-to-earnings ratios and other valuation measures, dividend and
profit growth, balance sheet strength and return on assets. A stock's liquidity
and volatility are also considered. The portfolio manager sells stocks in order
to adjust or rebalance the Fund's portfolio and to replace companies with
weakening fundamentals.

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

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

                         aggregate to the Fund's Class A, B and C shares in
                         excess of $2.5 billion, and [0.04%] representing the
                         Fund's organizational expenses as attributed to the
                         class ("Organizational Expenses").
                    (3)  Net Expenses reflects the effects of a contractual
                         agreement by PIMCO Advisors to waive, reduce or
                         reimburse its Administrative Fee for each class in an
                         amount that, in essence, is equal to the Fund's
                         Organizational Expenses attributed to the class.
                         Because the Organizational Expenses will all be
                         accounted for in the Fund's initial fiscal year, the
                         Fund's reasonable expectation is that the relevant
                         conditions will not continue after the Fund's fiscal
                         year ending June 30, 2001.

                    Examples.  The Examples are intended to help you compare the
                    cost of investing in Class A, B or C shares of the Fund with
                    the costs of investing in other mutual funds. The Examples
                    assume that you invest $10,000 in the noted class of shares
                    for the time periods indicated, your investment has a 5%
                    return each year, the reinvestment of all dividends and
                    distributions, and the Fund's operating expenses remain the
                    same. Although your actual costs may be higher or lower, the
                    Examples show what your costs would be based on these
                    assumptions./(1)/

                  (1) Due to the 12b-1 distribution fee imposed on Class B and
                      Class C shares, a Class B or Class C shareholders may,
                      depending upon the length of time the shares are held, pay
                      more than the economic equivalent of the maximum front-end
                      sales charges permitted by relevant rules of the National
                      Association of Securities Dealers, Inc.

                  (2) Other Expenses reflects a 0.70% Administrative Fee paid by
                      the class, which is subject to a reduction of 0.05% on
                      average daily net assets attributable in the aggregate to
                      the Fund's Class A, B and C shares in excess of $2.5
                      billion, and [0.04%] representing the Fund's
                      organizational expenses as attributed to the class
                      ("Organizational Expenses").

                  (3) Net Expenses reflects the effects of a contractual
                      agreement by PIMCO Advisors to waive, reduce or reimburse
                      its Administrative Fee for each class in an amount that,
                      in essence, is equal to the Fund's Organizational Expenses
                      attributed to the class. Because the Organizational
                      Expenses will all be accounted for in the Fund's initial
                      fiscal year, the Fund's reasonable expectation is that the
                      relevant conditions will not continue after the Fund's
                      fiscal year ending June 30, 2001.

                  Examples. The Examples are intended to help you compare the
                  cost of investing in Class A, B or C shares of the Fund with
                  the costs of investing in other mutual funds. The Examples
                  assume that you invest $10,000 in the noted class of shares
                  for the time periods indicated, your investment has a 5%
                  return each year, the reinvestment of all dividends and
                  distributions, and the Fund's operating expenses remain the
                  same. Although your actual costs may be higher or lower, the
                  Examples show what your costs would be based on these
                  assumptions./(1)

     The Fund seeks to achieve its investment objective by normally investing at
least 65% of its assets in an international portfolio of common stocks and other
equity securities of companies located throughout the world. Although the Fund
normally invests in issuers from at least five different countries, including
the United States, it may at times invest in fewer than five countries, or even
a single country. The Fund typically invests in approximately 50 to 60 stocks,
with each stock usually constituting from 1.25% to 2.5% of the Fund's portfolio.
The Fund may invest in both developed and developing, or "emerging," markets.
The Fund has no prescribed limits on geographic asset distribution and may
invest in any foreign securities market in the world. The Fund invests most of
its assets in foreign securities which trade in currencies other than the U.S.
dollar and may invest directly in foreign currencies

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

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

                      the Fund's Class A, B and C shares in excess of $2.5
                      billion, and [0.04%] representing the Fund's
                      organizational expenses as attributed to the class
                      ("Organizational Expenses").

                  (3) Net Expenses reflects the effects of a contractual
                      agreement by PIMCO Advisors to waive, reduce or reimburse
                      its Administrative Fee for each class in an amount that,
                      in essence, is equal to the Fund's Organizational Expenses
                      attributed to the class. Because the Organizational
                      Expenses will all be accounted for in the Fund's initial
                      fiscal year, the Fund's reasonable expectation is that the
                      relevant conditions will not continue after the Fund's
                      fiscal year ending June 30, 2001.

                  Examples. The Examples are intended to help you compare the
                  cost of investing in Class A, B or C shares of the Fund with
                  the costs of investing in other mutual funds. The Examples
                  assume that you invest $10,000 in the noted class of shares
                  for the time periods indicated, your investment has a 5%
                  return each year, the reinvestment of all dividends and
                  distributions, and the Fund's operating expenses remain the
                  same. Although your actual costs may be higher or lower, the
                  Examples show what your costs would be based on these
                  assumptions./(1)/

     The Fund seeks to achieve its investment objective by normally investing at
least 65% of its assets in an international portfolio of common stocks and other
equity securities of companies located in emerging market countries within
Europe, Asia, Latin America and Africa.  The Fund may also invest in securities
of foreign issuers traded on U.S. securities markets, but will normally not
invest in U.S. issuers.  However, the Fund has no prescribed limits on
geographic asset distribution and may invest in any foreign securities market in
the world.  The Fund invests most of its assets in foreign securities which
trade in currencies other than the U.S. dollar and may invest directly in
foreign currencies.

     The portfolio manager selects securities for the Fund using the Sub-
Adviser's "Growth at a Reasonable Price" (GARP) investment style.  The GARP
style uses a research-driven "bottom-up" approach that seeks to identify
companies with above-average long-term growth prospects and attractive
valuations and that possess a sustainable competitive advantage, such as
superior or innovative products, personnel and distribution systems.  In
selecting stocks, the portfolio manager analyzes a broad range of company
fundamentals, such as long-term growth prospects, price-to-earnings ratios and
other valuation measures, dividend and profit growth, balance sheet strength and
return on assets.  A stock's liquidity and volatility are also considered.  The
portfolio manager sells stocks in order to adjust or rebalance the Fund's
portfolio and to replace companies with weakening fundamentals.

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

Summary of Principal Risks

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

Market Risk

The market price of securities owned by a Fund may go up or down, sometimes
rapidly or unpredictably. Each of the Funds normally invests most of its assets
in common stocks and/or other equity securities. A principal risk of investing
in each Fund is that the equity securities in its portfolio will decline in
value due to factors affecting equity securities markets generally or particular
industries represented in those markets. The values of equity securities may
decline due to general market conditions which are not specifically related to a
particular company, such as real or perceived adverse economic conditions,
changes in the general outlook for corporate earnings, changes in interest or
currency rates or adverse investor sentiment generally. They may also decline
due to factors which affect a particular industry or industries, such as labor
shortages or increased production costs and competitive conditions within an
industry. Equity securities generally have greater price volatility than fixed
income securities.

Issuer Risk

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

Growth Securities Risk

Each Fund emphasizes investments in equity securities of companies that its
portfolio manager believes will experience relatively rapid earnings growth. The
Funds place particular emphasis on growth securities. Growth securities
typically trade at higher multiples of current earnings than other securities.
Therefore, the values of growth securities may be more sensitive to changes in
current or expected earnings than the values of other securities.

Value Securities Risk

The Funds may invest in companies that may not be expected to experience
significant earnings growth, but whose securities its portfolio manager believes
are selling at a price lower than their true value. The New Asia, Europe Growth
and Emerging Markets Funds place particular emphasis on value securities.
Companies that issue value securities may have experienced adverse business
developments or may be subject to special risks that have caused their
securities to be out of favor. If a portfolio manager's assessment of a
company's prospects is wrong, or if the market does not recognize the value of
the company, the price of its securities may decline or may not approach the
value that the portfolio manager anticipates.

Smaller Company Risk

The general risks associated with equity securities and liquidity risk are
particularly pronounced for securities of companies with smaller market
capitalizations. These companies may have limited product lines, markets or
financial resources or they may depend on a few key employees. Securities of
smaller companies may trade less frequently and in lesser volume than more
widely held securities and their values may fluctuate more sharply than other
securities. They may also trade in the over-the-counter market or on a regional
exchange, or may otherwise have limited liquidity.  The Small-Cap Technology
Fund has substantial exposure to this risk because it invests primarily in the
securities of companies with market capitalizations below $200 million.  The
Healthcare Innovation, Internet Innovation, Telecom Innovation, Electronics
Innovation, New Asia, Europe Growth, Select World and Emerging Markets Funds
also have significant exposure to this risk.

Liquidity Risk

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

Derivatives Risk

All of the Funds may use derivatives, which are financial contracts whose value
depends on, or is derived from, the value of an underlying asset, reference rate
or index. The various derivative instruments that the Funds may use are
referenced under "Characteristics and Risks of Securities and Investment
Techniques--Derivatives" in this Prospectus and described in more detail under
"Investment Objectives and Policies" in the Statement of Additional
Information. The Funds may sometimes use derivatives as part of a strategy
designed to reduce exposure to other risks, such as interest rate or currency
risk. The Funds may also use derivatives for leverage, which increases
opportunities for gain but also involves greater risk of loss due to leveraging
risk. A Fund's use of derivative instruments involves risks different from, or
possibly greater than, the risks associated with investing directly in
securities and other traditional investments. Derivatives are subject to a
number of risks described elsewhere in this section, such as liquidity risk,
market risk, credit risk and management risk. They also involve the risk of
mispricing or improper valuation and the risk that changes in the value of the
derivative may not correlate perfectly with the underlying asset, rate or index.
In addition, a Fund's use of derivatives may increase or accelerate the amount
of taxes payable by shareholders. A Fund investing in a derivative instrument
could lose more than the principal amount invested. Also, suitable derivative
transactions may not be available in all circumstances and there can be no
assurance that a Fund will engage in these transactions to reduce exposure to
other risks when that would be beneficial.

Foreign (non-U.S.) Investment Risk

A Fund that invests in foreign securities, and particularly the New Asia, Europe
Growth, Select World and Emerging Markets Funds, may experience more rapid and
extreme changes in value than Funds that invest exclusively in securities of
U.S. issuers or securities that trade exclusively in U.S. markets. The
securities markets of many foreign countries are relatively small, with a
limited number of companies representing a small number of industries.
Additionally, issuers of foreign securities are usually not subject to the same
degree of regulation as U.S. issuers. Reporting, accounting and auditing
standards of foreign countries differ, in some cases significantly, from U.S.
standards. Also, nationalization, expropriation or confiscatory taxation,

                                       33
<PAGE>

currency blockage, political changes or diplomatic developments could adversely
affect a Fund's investments in a foreign country. In the event of
nationalization, expropriation or other confiscation, a Fund could lose its
entire investment in foreign securities. To the extent that a Fund, such as the
New Asia, Europe Growth, Select World and Emerging Markets Funds, invests a
significant portion of its assets in a narrowly defined area such as Europe,
Asia or South America, the Fund will generally have more exposure to regional
economic risks associated with foreign investments. Adverse conditions in
certain regions (such as Southeast Asia) can also adversely affect securities of
other countries whose economies appear to be unrelated. In addition, special
U.S. tax considerations may apply to a Fund's investment in foreign securities.

Emerging Markets Risk

Foreign investment risk may be particularly high to the extent that a Fund
invests in emerging market securities of issuers based in countries with
developing economies. These securities may present market, credit, currency,
liquidity, legal, political and other risks different from, or greater than, the
risks of investing in developed foreign countries. The Emerging Markets Fund is
particularly susceptible to these risks because it invests principally in
companies located in emerging markets countries.  The New Asia and Select World
Funds also have substantial exposure to these risks because these Funds may
invest significant portions of their assets in emerging market securities.  In
addition, the risks associated with investing in a narrowly defined geographic
area (discussed above under "Foreign (non-U.S.) Investment Risk") are more
pronounced for the Funds that invest in emerging market countries.

Currency Risk

Funds that invest directly in foreign currencies or in securities that trade in,
and receive revenues in, foreign currencies are subject to the risk that those
currencies will decline in value relative to the U.S. Dollar, or, in the case of
hedging positions, that the U.S. Dollar will decline in value relative to the
currency being hedged.  The New Asia, Europe Growth, Select World and Emerging
Markets Funds are particularly sensitive to currency risk. Currency rates in
foreign countries may fluctuate significantly over short periods of time for a
number of reasons, including changes in interest rates, intervention (or the
failure to intervene) by U.S. or foreign governments, central banks or
supranational entities such as the International Monetary Fund, or by the
imposition of currency controls or other political developments in the U.S. or
abroad.

Focused
Investment Risk

Focusing Fund investments in a small number of issuers, industries or foreign
currencies increases risk. Funds, such as the Select World Fund, that invest in
a relatively small number of issuers may have more risk because changes in the
value of a single security or the impact of a single economic, political or
regulatory occurrence may have a greater adverse impact on the Fund's net asset
value. Some of those issuers also may present substantial credit or other risks.
The New Asia, Europe Growth, Select World and Emerging Markets Funds may be
subject to increased risk to the extent that they focus their investments in
securities denominated in a particular foreign currency or in a narrowly defined
geographic area outside the U.S. The Internet Innovation, Electronics Innovation
and Small-Cap Technology Funds are subject to risks prevalent in the Internet,
electronics and technology sectors, respectively, such as the risks of rapid
obsolescence of products and services, significant losses, increased volatility
of these companies' securities and limited operating histories, because they
"concentrate" their investments in these sectors. Similarly, the Telecom
Innovation and Healthcare Innovation Funds "concentrate" their investments in
the telecommunications and health care industries, respectively, and therefore
are subject to the risks particular to those industries, such as the risks
associated with additional government regulation of the telecommunications and
health care industries and changes to existing regulations and government
subsidy levels. Also, the Funds may from time to time have
                                       34
<PAGE>

greater risk to the extent they invest a substantial portion of their assets in
related industries such as "technology" or "financial and business
services," which may share common characteristics and react similarly to market
developments.

Leveraging Risk

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

Interest Rate Risk

To the extent that Funds purchase fixed income securities for investment or
defensive purposes, they will be subject to interest rate risk, a market risk
relating to investments in fixed income securities such as bonds and notes.   As
interest rates rise, the value of fixed income securities in a Fund's portfolio
are likely to decrease.  Securities with longer "durations" (defined below) tend
to be more sensitive to changes in interest rates, usually making them more
volatile than securities with shorter durations.  Duration is a measure of the
expected life of a fixed income security that is used to determine the
sensitivity of a security's price to changes in interest rates.  A Fund with a
longer average portfolio duration will be more sensitive to changes in interest
rates than a Fund with a shorter average portfolio duration.

Credit Risk

All of the Funds are subject to credit risk. This is the risk that the issuer or
the guarantor of a fixed income security, or the counterparty to a derivatives
contract, repurchase agreement or a loan of portfolio securities, is unable or
unwilling to make timely principal and/or interest payments, or to otherwise
honor its obligations. Securities are subject to varying degrees of credit risk,
which are often reflected in their credit ratings.

Management Risk

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

Management of the Funds

Investment Adviser and Administrator

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

PIMCO Advisors is located at 800 Newport Center Drive, Newport Beach, California
92660. Organized in 1987, PIMCO Advisors provides investment management and
advisory services to private accounts of institutional and individual clients
and to mutual funds. As of March 31, 2000, PIMCO Advisors and its subsidiary
partnerships had more than $264 billion in assets under management.


PIMCO Advisors has retained its subsidiary PIMCO/Allianz International Advisors
LLC to manage the investments of the New Asia, Europe Growth, Select World and
Emerging Markets Funds.  The PIMCO Equity Advisors division of PIMCO Advisors
manages the investments of the Healthcare Innovation, Internet Innovation,
Small-Cap Technology, Telecom Innovation and Electronics Innovation Funds (PIMCO
Equity Advisors and PIMCO/Allianz International Advisors LLC are each referred
to as a "Sub-Adviser" in this prospectus). See "Sub-Advisers" below.

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

Advisory Fees

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

The Funds will pay monthly advisory fees to PIMCO Advisors at the following
annual rates (stated as a percentage of the average daily net assets of each
Fund taken separately):



Fund                                                        Advisory Fees

Healthcare Innovation and Telecom Innovation Funds              0.70%

Europe Growth and Select World Funds                            0.75%

Internet Innovation, Small-Cap Technology and                   0.80%

Administrative Fees

Each Fund pays for the administrative services it requires under a fee structure
which is essentially fixed. Class A, Class B and Class C shareholders of each
Fund pay an administrative fee to PIMCO Advisors, computed as a percentage of
the Fund's assets attributable in the aggregate to those classes of shares.
PIMCO Advisors, in turn, provides or procures administrative services for Class
A, Class B and Class C shareholders and also bears the costs of various third-
party services required by the Funds, including audit, custodial, portfolio
accounting, legal, transfer agency and printing costs. The result of this fee
structure is an expense level for Class A, Class B and Class C shareholders of
each Fund that, with limited exceptions, is precise and predictable under
ordinary circumstances.

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

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


Investment Options -- Class A, B and C Shares

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

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

Class A Shares

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

                                       39
<PAGE>

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

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

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

Class B Shares

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

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

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

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

Class C Shares

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

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

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

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

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

Initial Sales Charges-- Class A Shares

Unless you are eligible for a waiver, the public offering price you pay when you
buy Class A shares of the Funds is the net asset value ("NAV") of the shares
plus an initial sales charge. The initial sales charge varies depending upon the
size of your purchase, as set forth below. No sales charge is imposed where
Class A shares are issued to you pursuant to the automatic reinvestment of
income dividends or capital gains distributions.

CDSCs on Class A Shares

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


How CDSCs are Calculated

A CDSC is imposed on redemptions of Class B and Class C shares (and where
applicable, Class A shares) on the amount of the redemption which causes the
current value of your account for the particular class of shares of a Fund to
fall below the total dollar amount of your purchase payments subject to the
CDSC. However, no CDSC is imposed if the shares redeemed have been acquired
through the reinvestment of dividends or capital gains distributions or if the
amount redeemed is derived from increases in the value of your account above the

                                       42
<PAGE>

amount of the purchase payments subject to the CDSC. CDSCs are deducted from the
proceeds of your redemption, not from amounts remaining in your account. In
determining whether a CDSC is payable, it is assumed that the purchase payment
from which the redemption is made is the earliest purchase payment for the
particular class of shares in your account (from which a redemption or exchange
has not already been effected).

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

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

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

Reductions and Waivers of Initial Sales Charges and CDSCs

The initial sales charges on Class A shares and the CDSCs on Class A, Class B
and Class C shares may be reduced or waived under certain purchase arrangements
and for certain categories of investors. Please see the Guide for details. The
Guide is available free of charge from the Distributor. See "How to Buy and
Sell Shares--PIMCO Funds Shareholders' Guide" below.

Distribution and Servicing (12b-1) Plans

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

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

                                              Servicing         Distribution
All Funds                                     Fee               Fee
Class A                                       0.25%             None
Class B                                       0.25%             0.75%
Class C                                       0.25%             0.75%

Because 12b-1 fees are paid out of a Fund's assets on an ongoing basis, over
time these fees will increase the cost of your investment and may cost you more
than sales charges which are deducted at the time of

                                       43
<PAGE>

investment. Therefore, although Class B and Class C shares do not pay initial
sales charges, the distribution fees payable on Class B and Class C shares may,
over time, cost you more than the initial sales charge imposed on Class A
shares. Also, because Class B shares convert into Class A shares after they have
been held for seven years and are not subject to distribution fees after the
conversion, an investment in Class C shares may cost you more over time than an
investment in Class B shares.

How Fund Shares Are Priced

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

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

Investments initially valued in currencies other than the U.S. dollar are
converted to U.S. dollars using exchange rates obtained from pricing services.
As a result, the NAV of a Fund's shares may be affected by changes in the value
of currencies in relation to the U.S. dollar. The value of securities traded in
markets outside the United States or denominated in currencies other than the
U.S. dollar may be affected significantly on a day that the New York Stock
Exchange is closed and an investor is not able to purchase, redeem or exchange
shares. In particular, calculation of the NAV of the New Asia, Europe Growth,
Select World and Emerging Markets Funds may not take place contemporaneously
with the determination of the prices of foreign securities used in NAV
calculations.

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

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

How to Buy and Sell Shares

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

PIMCO Funds Shareholders' Guide

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

 .   Automated telephone and wire transfer procedures

 .   Automatic purchase, exchange and withdrawal programs

 .   Programs that establish a link from your Fund account to your bank account

 .   Special arrangements for tax-qualified retirement plans

 .   Investment programs which allow you to reduce or eliminate the initial sales
    charges on Class A shares

 .   Categories of investors that are eligible for waivers or reductions of
    initial sales charges and CDSCs

Calculation of Share Price and Redemption Payments

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

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


Buying Shares

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

                                       45
<PAGE>

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

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

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

PIMCO Funds Distributors LLC
P.O. Box 9688
Providence, RI 02940-0926

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

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

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

Investment Minimums

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


             Initial Investment              Subsequent Investments
             ------------------              ----------------------
              $2,500 per Fund                     $100 per Fund


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

Small Account Fee

Because of the disproportionately high costs of servicing accounts with low
balances, if you have a direct account with the Distributor, you will be charged
a fee at the annual rate of $16 if your account balance for any Fund falls below
a minimum level of $2,500, except for Uniform Gift to Minors, IRA, Roth IRA and

                                       46
<PAGE>

Auto-Invest accounts for which the limit is $1,000. The fee also applies to
employer-sponsored retirement plan accounts, Money Purchase and/or Profit
Sharing plans, 401(k) plans, 403(b)(7) custodial accounts, SIMPLE IRAs, SEPs and
SAR/SEPs. (A separate custodial fee may apply to IRAs, Roth IRAs and other
retirement accounts.) However, you will not be charged this fee if the aggregate
value of all of your PIMCO Funds accounts is at least $50,000. Any applicable
small account fee will be deducted automatically from your below-minimum Fund
account in quarterly installments and paid to the Administrator. Each Fund
account will normally be valued, and any deduction taken, during the last five
business days of each calendar quarter. Lower minimum balance requirements and
waivers of the small account fee apply for certain categories of investors.
Please see the Guide for details.

Minimum Account Size

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

Exchanging Shares

Except as provided below and/or in the applicable Funds' or series'
prospectus(es), you may exchange your Class A, Class B or Class C shares of any
Fund for the same Class of shares of any other Fund or of another series of the
Trust or PIMCO Funds: Pacific Investment Management Series. Shares are exchanged
on the basis of their respective NAVs next calculated after your exchange order
is received by the Distributor. Currently, the Trust does not charge any
exchange fees or charges. Exchanges are subject to the $2,500 minimum initial
purchase requirements for each Fund, except with respect to tax-qualified
programs and exchanges effected through the PIMCO Funds Auto-Exchange plan. In
addition, an exchange is generally a taxable event which will generate capital
gains or losses, and special rules may apply in computing tax basis when
determining gain or loss. If you maintain your account with the Distributor, you
may exchange shares by completing a written exchange request and sending it to
PIMCO Funds Distributors LLC, P.O. Box 9688, Providence, RI 02940-0926. You can
get an exchange form by calling the Distributor at 1-800-426-0107.

The Trust reserves the right to refuse exchange purchases if, in the judgment of
PIMCO Advisors, the purchase would adversely affect a Fund and its shareholders.
In particular, a pattern of exchanges characteristic of "market-timing"
strategies may be deemed by PIMCO Advisors to be detrimental to the Trust or a
particular Fund. Currently, the Trust limits the number of "round trip"
exchanges an investor may make. An investor makes a "round trip" exchange when
the investor purchases shares of a particular Fund, subsequently exchanges those
shares for shares of a different PIMCO Fund and then exchanges back into the
originally purchased Fund. The Trust has the right to refuse any exchange for
any investor who completes (by making the exchange back into the shares of the

Selling Shares

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

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

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

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

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

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

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

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

If the proceeds of your redemption (i) are to be paid to a person other than the
record owner, (ii) are to be sent to an address other than the address of the
account on the Transfer Agent's records, and/or (iii) are to be paid to a
corporation, partnership, trust or fiduciary, the signature(s) on the redemption
request and on the certificates, if any, or stock power must be guaranteed as
described under "Signature Guarantee" below. The Distributor may, however,
waive the signature guarantee requirement for redemptions up to $2,500 by a
trustee of a qualified retirement plan, the administrator for which has an
agreement with the Distributor.

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

     .   telephone requests to the Transfer Agent
     .   PIMCO Funds Automated Telephone System (ATS)

                                       48
<PAGE>

     .   expedited wire transfers
     .   automatic Withdrawal Plan
     .   PIMCO Funds Fund Link

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

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

Redemptions of Fund shares may be suspended when trading on the New York Stock
Exchange is restricted or during an emergency which makes it impracticable for
the Funds to dispose of their securities or to determine fairly the value of
their net assets, or during any other period as permitted by the Securities and
Exchange Commission for the protection of investors. Under these and other
unusual circumstances, the Trust may suspend redemptions or postpone payments
for more than seven days, as permitted by law.

Timing of Redemption Payments

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

Redemptions In Kind

The Trust had agreed to redeem shares of each Fund solely in cash up to the
lesser of $250,000 or 1% of the Fund's net assets during any 90-day period for
any one shareholder. In consideration of the best interests of the remaining
shareholders, the Trust may pay any redemption proceeds exceeding this amount in
whole or in part by a distribution in kind of securities held by a Fund in lieu
of cash. It is highly unlikely that your shares would ever be redeemed in kind.
If your shares are redeemed in kind, you should expect to incur transaction
costs upon the disposition of the securities received in the distribution.

Certificated Shares

If you are redeeming shares for which certificates have been issued, the
certificates must be mailed to or deposited with the Trust, duly endorsed or
accompanied by a duly endorsed stock power or by a written request for
redemption. Signatures must be guaranteed as described under "Signature
Guarantee" below. The Trust may request further documentation from institutions
or fiduciary accounts, such as corporations, custodians (e.g., under the Uniform
Gifts to Minors Act), executors, administrators, trustees or guardians. Your
redemption request and stock power must be signed exactly as the account is
registered, including indication of any special capacity of the registered
owner.

                                       49
<PAGE>

Signature Guarantee

When a signature guarantee is called for, you should have "Signature
Guaranteed" stamped under your signature and guaranteed by any of the following
entities: U.S. banks, foreign banks having a U.S. correspondent bank, credit
unions, savings associations, U.S. registered dealers and brokers, municipal
securities dealers and brokers, government securities dealers and brokers,
national securities exchanges, registered securities associations and clearing
agencies (each an "Eligible Guarantor Institution"). The Distributor reserves
the right to reject any signature guarantee pursuant to its written signature
guarantee standards or procedures, which may be revised in the future to permit
it to reject signature guarantees from Eligible Guarantor Institutions that do
not, based on credit guidelines, satisfy such written standards or procedures.
The Trust may change the signature guarantee requirements from time to time upon
notice to shareholders, which may be given by means of a new or supplemented
Prospectus.

Fund Distributions

Each Fund distributes substantially all of its net investment income to
shareholders in the form of dividends. You begin earning dividends on Fund
shares the day after the Trust receives your purchase payment. Dividends paid by
each Fund with respect to each class of shares are calculated in the same manner
and at the same time, but dividends on Class B and Class C shares are expected
to be lower than dividends on Class A shares as a result of the distribution
fees applicable to Class B and Class C shares. The following shows when each
Fund intends to declare and distribute income dividends to shareholders of
record.

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

You can choose from the following distribution options:

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

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

                                       50

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

You do not pay any sales charges on shares you receive through the reinvestment
of Fund distributions.

If you elect to receive Fund distributions in cash and the postal or other
delivery service is unable to deliver checks to your address of record, the
Trust's Transfer Agent will hold the returned checks for your benefit in a non-
interest bearing account.

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


Tax Consequences

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

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

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

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

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

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

Characteristics and Risks of Securities
and Investment Techniques

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

Fixed Income Securities and Defensive Strategies

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

The Healthcare Innovation, Internet Innovation, Small-Cap Technology, Telecom
Innovation, Electronics Innovation, New Asia, Europe Growth, Select World and
Emerging Markets Funds will each invest primarily in common stocks, and may also
invest in other kinds of equity securities, including preferred stocks and
securities (including fixed income securities and warrants) convertible into or
exercisable for common stocks. Each of these Funds may invest a portion of its
assets in fixed income securities. The Funds may temporarily hold up to 100% of
their assets in short-term U.S. Government securities and other money market
instruments for defensive purposes in response to unfavorable market and other
conditions. The New Asia, Europe Growth, Select World and Emerging Markets Funds
may also hold up to 100% of their assets in other domestic fixed income, foreign
fixed income and equity securities principally traded in the U.S., including
obligations issued or guaranteed by a foreign government or its agencies,
authorities or instrumentalities, corporate bonds and American Depository
Receipts, for temporary defensive purposes.

The temporary defensive strategies described in this section would be
inconsistent with the investment objective and principal investment strategies
of each of the noted Funds and may adversely affect the Fund's ability to
achieve its investment objective.

Companies With Smaller Market Capitalizations

Each of the Funds may invest in securities of companies with market
capitalizations that are small compared to other publicly traded companies. The
Small-Cap Technology Fund invests primarily in smaller companies and is
especially sensitive to the risks described below. In addition, the Healthcare
Innovation, Internet Innovation, Telecom Innovation, Electronics Innovation, New
Asia, Europe Growth, Select World and Emerging Markets Funds generally have
significant exposure to these risks.

                                       52
<PAGE>

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

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

The Funds may purchase securities in initial public offerings (IPOs). These
securities are subject to many of the same risks of investing in companies with
smaller market capitalizations. Securities issued in IPOs have no trading
history, and information about the companies may be available for very limited
periods. In addition, the prices of securities sold in IPOs may be highly
volatile. A Fund may not be able to invest in securities issued in IPOs to the
extent desired because, for example, only a small portion of the securities
being offered in an IPO may be made available to the Fund or because under
certain market conditions few companies may issue securities in IPOs.

Foreign Securities

The New Asia, Europe Growth, Select World and Emerging Markets Funds normally
invest principally in securities of foreign issuers, securities traded
principally in securities markets outside the United States and/or securities
denominated in foreign currencies (together, "foreign securities"). The
Healthcare Innovation, Internet Innovation, Small-Cap Technology, Telecom
Innovation and Electronics Innovation Funds may invest up to 15% of their
respective assets in foreign securities.

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

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

                                       53
<PAGE>

invest in these securities. These risks include: differences in accounting,
auditing and financial reporting standards; generally higher commission rates on
foreign portfolio transactions; the possibility of nationalization,
expropriation or confiscatory taxation; adverse changes in investment or
exchange control regulations; and political instability. Individual foreign
economies may differ favorably or unfavorably from the U.S. economy in such
respects as growth of gross domestic product, rate of inflation, capital
reinvestment, resources, self-sufficiency and balance of payments position. The
securities markets, values of securities, yields and risks associated with
foreign securities markets may change independently of each other. Also, foreign
securities and dividends and interest payable on those securities may be subject
to foreign taxes, including taxes withheld from payments on those securities.
Foreign securities often trade with less frequency and volume than domestic
securities and therefore may exhibit greater price volatility. Investments in
foreign securities may also involve higher custodial costs than domestic
investments and additional transaction costs with respect to foreign currency
conversions. Changes in foreign exchange rates also will affect the value of
securities denominated or quoted in foreign currencies.

Emerging Market Securities

Each Fund may invest in securities of issuers based in or that trade principally
in countries with developing (or "emerging market") economies. The Emerging
Markets Fund is particularly susceptible to these risks because it invests
principally in companies located in emerging markets countries.  The New Asia
and Select World Funds also have substantial exposure to these risks because
these Funds may invest significant portions of their assets in emerging market
securities. Investing in emerging market securities imposes risks different
from, or greater than, risks of investing in domestic securities or in foreign,
developed countries. These risks include: smaller market capitalization of
securities markets, which may suffer periods of relative illiquidity;
significant price volatility; restrictions on foreign investment; and possible
repatriation of investment income and capital. In addition, foreign investors
may be required to register the proceeds of sales, and future economic or
political crises could lead to price controls, forced mergers, expropriation or
confiscatory taxation, seizure, nationalization or the creation of government
monopolies. The currencies of emerging market countries may experience
significant declines against the U.S. dollar, and devaluation may occur
subsequent to investments in these currencies by a Fund. Inflation and rapid
fluctuations in inflation rates have had, and may continue to have, negative
effects on the economies and securities markets of certain emerging market
countries.

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

  Special Risks of Investing in Russian and Other Eastern European Securities.
The Select World and Emerging Markets Funds may invest a portion of their assets
in securities of issuers located in Russia and in other Eastern European
countries. While investments in securities of such issuers are subject generally
to the same risks associated with investments in other emerging market countries
described above, the political, legal and operational risks of investing in
Russian and other Eastern European issuers, and of having assets custodied
within these countries, may be particularly acute. A risk of particular note
with respect to direct investment in Russian securities is the way in which
ownership of shares of companies is normally recorded.

                                       54
<PAGE>

When a Fund invests in a Russian issuer, it will normally receive a "share
extract," but that extract is not legally determinative of ownership. The
official record of ownership of a company's share is maintained by the company's
share registrar. Such share registrars are completely under the control of the
issuer, and investors are provided with few legal rights against such
registrars.

Foreign Currencies

A Fund that invests directly in foreign currencies or in securities that trade
in, and receive revenues in, foreign currencies will be subject to currency
risk. The New Asia, Europe Growth, Select World and Emerging Markets Funds are
particularly sensitive to this risk.

Foreign currency exchange rates may fluctuate significantly over short periods
of time. They generally are determined by supply and demand and the relative
merits of investments in different countries, actual or perceived changes in
interest rates and other complex factors. Currency exchange rates also can be
affected unpredictably by intervention (or the failure to intervene) by U.S. or
foreign governments or central banks, or by currency controls or political
developments. For example, significant uncertainty surrounds the recent
introduction of the euro (a common currency unit for the European Union) in
January 1999 and the effect it may have on the value of securities denominated
in local European currencies. The Europe Growth Fund is especially susceptible
to risks associated with the introduction of the euro because it invests
principally in European companies, many of which are located in European
Monetary Union countries.  The euro and other currencies in which the Funds'
assets are denominated may be devalued against the U.S. dollar, resulting in a
loss to the Funds.

  Foreign Currency Transactions.   The Funds may enter into forward foreign
currency exchange contracts to reduce the risks of adverse changes in foreign
exchange rates. In addition, the Funds may buy and sell foreign currency futures
contracts and options on foreign currencies and foreign currency futures. A
forward foreign currency exchange contract, which involves an obligation to
purchase or sell a specific currency at a future date at a price set at the time
of the contract, reduces a Fund's exposure to changes in the value of the
currency it will deliver and increases its exposure to changes in the value of
the currency it will receive for the duration of the contract. The effect on the
value of a Fund is similar to selling securities denominated in one currency and
purchasing securities denominated in another currency. Contracts to sell foreign
currency would limit any potential gain which might be realized by a Fund if the
value of the hedged currency increases. A Fund may enter into these contracts to
hedge against foreign exchange risk arising from the Fund's investment or
anticipated investment in securities denominated in foreign currencies. Suitable
hedging transactions may not be available in all circumstances and there can be
no assurance that a Fund will engage in such transactions at any given time or
from time to time. Also, such transactions may not be successful and may
eliminate any chance for a Fund to benefit from favorable fluctuations in
relevant foreign currencies.

The New Asia, Europe Growth, Select World and Emerging Markets Funds may also
enter into these contracts for purposes of increasing exposure to a foreign
currency or to shift exposure to foreign currency fluctuations from one currency
to another. To the extent that it does so, a Fund will be subject to the
additional risk that the relative value of currencies will be different than
anticipated by the Fund's portfolio manager.  The Funds may use one currency (or
a basket of currencies) to hedge against adverse changes in the value of another
currency (or a basket of currencies) when exchange rates between the two
currencies are positively correlated. Each Fund will segregate assets determined
to be liquid by PIMCO Advisors or the Fund's Sub-Adviser in accordance with
procedures established by the Board of Trustees to cover its obligations under
forward foreign currency exchange contracts entered into for non-hedging
purposes.

                                       55
<PAGE>

Corporate Debt Securities

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

Convertible Securities

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

Derivatives

Each Fund may, but is not required to, use a number of derivative instruments
for risk management purposes or as part of its investment strategies. Generally,
derivatives are financial contracts whose value depends upon, or is derived
from, the value of an underlying asset, reference rate or index, and may relate
to stocks, bonds, interest rates, currencies or currency exchange rates,
commodities and related indexes. A portfolio manager may decide not to employ
any of these strategies and there is no assurance that any derivatives strategy
used by a Fund will succeed.

Examples of derivative instruments include options contracts, futures contracts,
options on futures contracts and swap agreements. The Funds may purchase and
sell (write) call and put options on securities, securities indexes and foreign
currencies. Each Fund may purchase and sell futures contracts and options
thereon with respect to securities, securities indexes and foreign currencies.
A description of these and other derivative instruments that the Funds may use
are described under "Investment Objectives and Policies" in the Statement of
Additional Information.

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

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

                                       56
<PAGE>

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

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

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

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

  Market and Other Risks Like most other investments, derivative instruments are
subject to the risk that the market value of the instrument will change in a way
detrimental to a Fund's interest. If a portfolio manager incorrectly forecasts
the values of securities, currencies or interest rates or other economic factors
in using derivatives for a Fund, the Fund might have been in a better position
if it had not entered into the transaction at all. While some strategies
involving derivative instruments can reduce the risk of loss, they can also
reduce the opportunity for gain or even result in losses by offsetting favorable
price movements in other Fund investments. A Fund may also have to buy or sell a
security at a disadvantageous time or price because the Fund is legally required
to maintain offsetting positions or asset coverage in connection with certain
derivatives transactions.

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

Equity-Linked Securities

The Funds may invest in equity-linked securities. Equity-linked securities are
privately issued securities whose investment results are designed to correspond
generally to the performance of a specified stock index or "basket" of stocks,
or sometimes a single stock. To the extent that the Funds invest in equity-
linked securities whose return corresponds to the performance of a foreign
securities index or one or more of foreign stocks,

                                       57
<PAGE>

investing in equity-linked securities will involve risks similar to the risks of
investing in foreign equity securities. See "Foreign Securities" above. In
addition, the Funds bear the risk that the issuer of an equity-linked security
may default on its obligations under the security. Equity-linked securities may
be considered illiquid and thus subject to each Fund's restrictions on
investments in illiquid securities.

Credit Ratings and Unrated Securities

The Funds may invest in securities based on their credit ratings assigned by
rating agencies such as Moody's Investors Service, Inc. ("Moody's") and
Standard and Poor's Ratings Services ("S&P"). Moody's, S&P and other rating
agencies are private services that provide ratings of the credit quality of
fixed income securities, including convertible securities. The Appendix to the
Statement of Additional Information describes the various ratings assigned to
fixed income securities by Moody's and S&P. Ratings assigned by a rating agency
are not absolute standards of credit quality and do not evaluate market risk.
Rating agencies may fail to make timely changes in credit ratings and an
issuer's current financial condition may be better or worse than a rating
indicates. A Fund will not necessarily sell a security when its rating is
reduced below its rating at the time of purchase. PIMCO Advisors and the Sub-
Advisers do not rely solely on credit ratings, and develop their own analysis of
issuer credit quality.

A Fund may purchase unrated securities (which are not rated by a rating agency)
if its portfolio manager determines that the security is of comparable quality
to a rated security that the Fund may purchase. Unrated securities may be less
liquid than comparable rated securities and involve the risk that the portfolio
manager may not accurately evaluate the security's comparative credit rating.

High Yield Securities

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

Loans of Portfolio Securities

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

Short Sales

Each Fund may make short sales as part of its overall portfolio management
strategies or to offset a potential decline in the value of a security. A short
sale involves the sale of a security that is borrowed from a broker or other
institution to complete the sale. A Fund may only enter into short selling
transactions if the security sold short is held in the Fund's portfolio or if
the Fund has the right to acquire the security without the payment of

                                       58
<PAGE>

further consideration. For these purposes, a Fund may also hold or have the
right to acquire securities which, without the payment of any further
consideration, are convertible into or exchangeable for the securities sold
short. Short sales expose a Fund to the risk that it will be required to
acquire, convert or exchange securities to replace the borrowed securities (also
known as "covering" the short position) at a time when the securities sold
short have appreciated in value, thus resulting in a loss to the Fund.

When-Issued, Delayed Delivery and Forward Commitment Transactions

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

Repurchase Agreements

Each Fund may enter into repurchase agreements, in which the Fund purchases a
security from a bank or broker-dealer that agrees to repurchase the security at
the Fund's cost plus interest within a specified time. If the party agreeing to
repurchase should default, the Fund will seek to sell the securities which it
holds. This could involve procedural costs or delays in addition to a loss on
the securities if their value should fall below their repurchase price. Those
Funds whose investment objectives do not include the earning of income will
invest in repurchase agreements only as a cash management technique with respect
to that portion of its portfolio maintained in cash. Repurchase agreements
maturing in more than seven days are considered illiquid securities.

Reverse Repurchase Agreements And Other Borrowings

Each Fund may enter into reverse repurchase agreements, subject to the Fund's
limitations on borrowings. A reverse repurchase agreement involves the sale of a
security by a Fund and its agreement to repurchase the instrument at a specified
time and price, and may be considered a form of borrowing for some purposes. A
Fund will segregate assets determined to be liquid by PIMCO Advisors or a Sub-
Adviser in accordance with procedures established by the Board of Trustees to
cover its obligations under reverse repurchase agreements. A Fund also may
borrow money for investment purposes subject to any policies of the Fund
currently described in this Prospectus or in the Statement of Additional
Information. Reverse repurchase agreements and other forms of borrowings may
create leveraging risk for a Fund.

Illiquid Securities

Each Fund may invest in securities that are illiquid so long as not more than
15% of the value of the Fund's net assets (taken at market value at the time of
investment) would be invested in such securities. Certain illiquid securities
may require pricing at fair value as determined in good faith under the
supervision of the Board of Trustees. A portfolio manager may be subject to
significant delays in disposing of illiquid securities held by a Fund, and
transactions in illiquid securities may entail registration expenses and other
transaction costs that are higher than those for transactions in liquid
securities. The term "illiquid securities" for this purpose means securities
that cannot be disposed of within seven days in the ordinary course of business
at approximately the amount at which a Fund has valued the securities. Please
see "Investment Objectives and Policies" in the Statement of Additional
Information for a listing of various securities that are generally considered to
be

                                       59
<PAGE>

illiquid for these purposes. Restricted securities, i.e., securities subject to
legal or contractual restrictions on resale, may be illiquid. However, some
restricted securities (such as securities issued pursuant to Rule 144A under the
Securities Act of 1933 and certain commercial paper) may be treated as liquid,
although they may be less liquid than registered securities traded on
established secondary markets.

Investment in Other Investment Companies

The New Asia, Europe Growth, Select World and Emerging Markets Funds may invest
up to [10%] of their assets in securities of other investment companies, such as
closed-end management investment companies, or in pooled accounts or other
investment vehicles which invest in foreign markets.  The Healthcare Innovation,
Internet Innovation, Small-Cap Technology, Telecom Innovation and Electronics
Innovation Funds may invest up to 5% of their assets in such securities.  As a
shareholder of an investment company, a Fund may indirectly bear service and
other fees which are in addition to the fees the Fund pays its service
providers.


Portfolio Turnover

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


Changes in Investment Objectives and Policies

The investment objective of each Fund described in this Prospectus may be
changed by the Board of Trustees without shareholder approval.  Unless otherwise
stated in the Statement of Additional Information, all investment policies of
the Funds may be changed by the Board of Trustees without shareholder approval.
If there is a change in a Fund's investment objective or policies, including a
change approved by shareholder vote, shareholders should consider whether the
Fund remains an appropriate investment in light of their then current financial
position and needs.


New Funds

In addition to the risks described under "Summary of Principal Risks" above
and in this section, the Funds are newly formed and therefore have no history
upon which investors can evaluate their likely performance. Accordingly, there
can be no assurance that the Funds will achieve their investment objective.
Also, it is possible that the Funds may invest in securities offered in initial
public offerings and other similar transactions which, because of each Fund's
size, have a disproportionate impact on each Fund's performance results. The
Funds would not necessarily have achieved the same performance results if their
aggregate net assets had been greater.


Percentage Investment Limitations

                                       60
<PAGE>

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

Other Investments and Techniques

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

     The Fund seeks to achieve its investment objective by normally investing at
least 65% of its assets in securities of companies principally engaged in the
design, manufacture or sale of new, creative or different, or "innovative,"
products or services used for or in connection with health care or medicine.
These companies may include, for example, pharmaceutical companies, companies
involved in biotechnology, medical diagnostic, biochemical or other health care
research and development, companies involved in the operation of health care
facilities, and other companies involved in the design, manufacture or sale of
health care-related products or services such as medical, dental and optical
products, hardware or services. Although the Fund emphasizes companies which
utilize health care technologies, it is not required to invest exclusively in a
particular business sector or industry, and at any time may not be invested in
any of the industry sectors listed above.

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

     Although the Fund invests principally in common stocks, the Fund may also
invest in other types of equity securities, including preferred stocks and
convertible securities. The Fund may invest up to 15% of its assets in foreign
securities, usually in the form of American Depository Receipts.

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

Risks           could adversely affect its net asset value, yield and total
                return, are:

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

Performance     The Fund recently commenced operations and does not yet have a

</TABLE>

          (1)   Other Expenses, which are based on estimated amounts for the
                Fund's initial fiscal year, reflect a 0.25% Administrative Fee
                paid by the class and [0.04%] representing the Fund's
                organizational expenses as attributed to the class
                ("Organizational Expenses").

          (2)   Net Expenses reflect the effect of a contractual agreement by
                PIMCO Advisors to waive, reduce or reimburse its Administrative
                Fees for each class in an amount that, in essence, is equal to
                the Fund's Organizational Expenses attributed to the class.
                Because the Organizational Expenses will all be accounted for in
                the Fund's initial fiscal year, the Fund's reasonable
                expectation is that the relevant conditions will not continue
                after the Fund's fiscal year ending June 30, 2001.


          Examples. The Examples below are intended to help you compare the cost
          of investing in Institutional Class or Administrative Class shares of
          the Fund with the costs of investing in other mutual funds. The
          Examples assume that you invest $10,000 in the noted class of shares
          for the time periods indicated, and then redeem all your shares at the
          end of those periods. The Examples also assume that your investment
          has a 5% return each year, the reinvestment of all dividends and
          distributions, and the Fund's operating expenses remain the same.
          Although your actual costs may be higher or lower, the Examples show
          what your costs would be based on these assumptions./(1)/

     The Fund seeks to achieve its investment objective by normally investing at
least 65% of its assets in common stocks of technology and technology-related
companies with market capitalizations of between $100 million and $2 billion at
the time of investment. The Fund identifies its investment universe of
technology-related companies primarily by reference to classifications made by
independent firms, such as Standard & Poor's (for example, companies classified
as "Information Technology" companies), and by identifying companies that
derive a substantial portion of their revenues from the manufacture, sale and/or
service of technological products. Although the Fund emphasizes companies which
utilize technologies, it is not required to invest exclusively in a particular
business sector or industry.

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

     Although the Fund invests principally in common stocks, the Fund may also
invest in other types of equity securities, including preferred stocks and
convertible securities.  The Fund may invest up to 15% of its assets in foreign
securities, usually in the form of American Depository Receipts.

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

                         Because the Organizational Expenses will all be
                         accounted for in the Fund's initial fiscal year, the
                         Fund's reasonable expectation is that the relevant

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

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

     Although the Fund invests principally in common stocks, the Fund may also
invest in other types of equity securities, including preferred stocks and
convertible securities. The Fund may invest up to 15% of its assets in foreign
securities, usually in the form of American Depository Receipts.

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

                         Organizational Expenses attributed to the class.
                         Because the Organizational Expenses will all be
                         accounted for in the Fund's initial fiscal year, the
                         Fund's reasonable expectation is that the relevant

                    compare the cost of investing in Institutional Class or

                    investing in other mutual funds. The Examples assume that
                    you invest $10,000 in the noted class of shares for the time
                    periods indicated, and then redeem all your shares at the

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

     The Fund seeks to achieve its investment objective by normally investing at
least 65% of its assets in an international portfolio of common stocks and other
equity securities of companies located in Asia. The Fund will primarily invest
in securities of companies located in the Far East, including Australia, China,
Hong Kong, Japan, Indonesia, India, Malaysia, New Zealand, the Philippines,
Singapore, South Korea, Taiwan and Thailand, although the Fund will not
necessarily be invested in all of these countries at any time. The Fund may also
invest in securities of foreign issuers traded on U.S. securities markets, but
will normally not invest in U.S. issuers. However, the Fund has no prescribed
limits on geographic asset distribution and may invest in any foreign securities
market in the world. The Fund invests most of its assets in foreign securities
which trade in currencies other than the U.S. dollar and may invest directly in
foreign currencies.

     The portfolio manager selects securities for the Fund using the Sub-
Adviser's "Growth at a Reasonable Price" (GARP) investment style. The GARP style
uses a research-driven "bottom-up" approach that seeks to identify companies
with above-average long-term growth prospects and attractive valuations and that
possess a sustainable competitive advantage, such as superior or innovative
products, personnel and distribution systems. In selecting stocks, the portfolio
manager analyzes a broad range of company fundamentals, such as long-term growth
prospects, price-to-earnings ratios and other valuation measures, dividend and
profit growth, balance sheet strength and return on assets. A stock's liquidity
and volatility are also considered. The portfolio manager sells stocks in order
to adjust or rebalance the Fund's portfolio and to replace companies with
weakening fundamentals.

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

                         Because the Organizational Expenses will all be
                         accounted for in the Fund's initial fiscal year, the

</TABLE>

          The Fund seeks to achieve its investment objective by normally
investing at least 65% of its assets in an international portfolio of common
stocks and other equity securities of companies located throughout the world.
Although the Fund normally invests in issuers from at least five different
countries, including the United States, it may at times invest in fewer than
five countries, or even a single country. The Fund typically invests in
approximately 50 to 60 stocks, with each stock usually constituting from 1.25%
to 2.5% of the Fund's portfolio. The Fund may invest in both developed and
developing, or "emerging," markets. The Fund has no prescribed limits on
geographic asset distribution and may invest in any foreign securities market in
the world. The Fund invests most of its assets in foreign securities which trade
in currencies other than the U.S. dollar and may invest directly in foreign
currencies.

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

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

stocks and other equity securities of companies located in emerging market
countries within Europe, Asia, Latin America and Africa. The Fund may also
invest in securities of foreign issuers traded on U.S. securities markets, but
will normally not invest in U.S. issuers. However, the Fund has no prescribed
limits on geographic asset distribution and may invest in any foreign securities
market in the world. The Fund invests most of its assets in foreign securities
which trade in currencies other than the U.S. dollar and may invest directly in
foreign currencies.

          The portfolio manager selects securities for the Fund using the Sub-
Adviser's "Growth at a Reasonable Price" (GARP) investment style. The GARP style
uses a research-driven "bottom-up" approach that seeks to identify companies
with above-average long-term growth prospects and attractive valuations and that
possess a sustainable competitive advantage, such as superior or innovative
products, personnel and distribution systems. In selecting stocks, the portfolio
manager analyzes a broad range of company fundamentals, such as long-term growth
prospects, price-to-earnings ratios and other valuation measures, dividend and
profit growth, balance sheet strength and return on assets. A stock's liquidity
and volatility are also considered. The portfolio manager sells stocks in order
to adjust or rebalance the Fund's portfolio and to replace companies with
weakening fundamentals.

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

                    could adversely affect its net asset value, yield and total

                         Organizational Expenses attributed to the class.
                         Because the Organizational Expenses will all be
                         accounted for in the Fund's initial fiscal year, the
                         Fund's reasonable expectation is that the relevant
                         conditions will not continue after the Fund's fiscal

                    investing in other mutual funds. The Examples assume that
                    you invest $10,000 in the noted class of shares for the time

                    all dividends and distributions, and the Fund's operating
                    expenses remain the same. Although your actual costs may be

Summary of Principal Risks


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

Market Risk

The market price of securities owned by a Fund may go up or down, sometimes
rapidly or unpredictably. Each of the Funds normally invests most of its assets
in common stocks and/or other equity securities. A principal risk of investing
in each Fund is that the equity securities in its portfolio will decline in
value due to factors affecting equity securities markets generally or particular
industries represented in those markets. The values of equity securities may
decline due to general market conditions which are not specifically related to a
particular company, such as real or perceived adverse economic conditions,
changes in the general outlook for corporate earnings, changes in interest or
currency rates or adverse investor sentiment generally. They may also decline
due to factors which affect a particular industry or industries, such as labor
shortages or increased production costs and competitive conditions within an
industry. Equity securities generally have greater price volatility than fixed
income securities.

Issuer Risk

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

Growth Securities Risk

Each Fund emphasizes investments in equity securities of companies that its
portfolio manager believes will experience relatively rapid earnings growth. The
Funds place particular emphasis on growth securities. Growth securities
typically trade at higher multiples of current earnings than other securities.
Therefore, the values of growth securities may be more sensitive to changes in
current or expected earnings than the values of other securities.

Value Securities Risk

The Funds may invest in companies that may not be expected to experience
significant earnings growth, but whose securities its portfolio manager believes
are selling at a price lower than their true value. The New Asia, Europe Growth
and Emerging Markets Funds place particular emphasis on value securities.
Companies that issue value securities may have experienced adverse business
developments or may be subject to special risks that have caused their
securities to be out of favor. If a portfolio manager's assessment of a
company's prospects is wrong, or if the market does not recognize the value of
the company, the price of its securities may decline or may not approach the
value that the portfolio manager anticipates.

Smaller Company Risk

The general risks associated with equity securities and liquidity risk are
particularly pronounced for securities of companies with smaller market
capitalizations. These companies may have limited product lines, markets or
financial resources or they may depend on a few key employees. Securities of
smaller companies may trade less frequently and in lesser volume than more
widely held securities and their values may fluctuate more sharply than other
securities. They may also trade in the over-the-counter market or on a regional
exchange, or may otherwise have limited liquidity. The Small-Cap Technology Fund
has substantial exposure to this risk because it invests primarily in the
securities of companies with market capitalizations below $200 million. The
Healthcare Innovation, Internet Innovation, Telecom Innovation, Electronics
Innovation, New Asia, Europe Growth, Select World and Emerging Markets Funds
also have significant exposure to this risk

                                       23
<PAGE>

because they invest substantial assets in companies with medium-sized market
capitalizations, which are smaller and generally less-seasoned than the largest
companies.

Liquidity Risk

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

Derivatives Risk

All of the Funds may use derivatives, which are financial contracts whose value
depends on, or is derived from, the value of an underlying asset, reference rate
or index. The various derivative instruments that the Funds may use are
referenced under "Characteristics and Risks of Securities and Investment
Techniques--Derivatives" in this Prospectus and described in more detail under
"Investment Objectives and Policies" in the Statement of Additional Information.
The Funds may sometimes use derivatives as part of a strategy designed to reduce
exposure to other risks, such as interest rate or currency risk. The Funds may
also use derivatives for leverage, which increases opportunities for gain but
also involves greater risk of loss due to leveraging risk. A Fund's use of
derivative instruments involves risks different from, or possibly greater than,
the risks associated with investing directly in securities and other traditional
investments. Derivatives are subject to a number of risks described elsewhere in
this section, such as liquidity risk, market risk, credit risk and management
risk. They also involve the risk of mispricing or improper valuation and the
risk that changes in the value of the derivative may not correlate perfectly
with the underlying asset, rate or index. In addition, a Fund's use of
derivatives may increase or accelerate the amount of taxes payable by
shareholders. A Fund investing in a derivative instrument could lose more than
the principal amount invested. Also, suitable derivative transactions may not be
available in all circumstances and there can be no assurance that a Fund will
engage in these transactions to reduce exposure to other risks when that would
be beneficial.

Foreign (non-U.S.) Investment Risk

A Fund that invests in foreign securities, and particularly the New Asia, Europe
Growth, Select World and Emerging Markets Funds, may experience more rapid and
extreme changes in value than Funds that invest exclusively in securities of
U.S. issuers or securities that trade exclusively in U.S. markets. The
securities markets of many foreign countries are relatively small, with a
limited number of companies representing a small number of industries.
Additionally, issuers of foreign securities are usually not subject to the same
degree of regulation as U.S. issuers. Reporting, accounting and auditing
standards of foreign countries differ, in some cases significantly, from U.S.
standards. Also, nationalization, expropriation or confiscatory taxation,
currency blockage, political changes or diplomatic developments could adversely
affect a Fund's investments in a foreign country. In the event of
nationalization, expropriation or other confiscation, a Fund could lose its
entire investment in foreign securities. To the extent that a Fund, such as New
Asia, Europe Growth, Select World and Emerging Markets Funds, invests a
significant portion of its assets in a narrowly defined geographic area such as
Europe, Asia or South America, the Fund will generally have more exposure to
regional economic risks associated with foreign investments. Adverse conditions
in certain regions (such as Southeast Asia) can also adversely affect securities
of other countries whose economies appear to be unrelated. In addition, special
U.S. tax considerations may apply to a Fund's investment in foreign securities.

Emerging Markets Risk

Foreign investment risk may be particularly high to the extent that a Fund
invests in emerging market securities of issuers based in countries with
developing economies. These securities may present market, credit, currency,
liquidity, legal, political and other risks different from, or greater than, the
risks of investing in developed foreign countries. The Emerging Markets Fund is
particularly susceptible to these risks because it invests principally in
companies located in emerging markets countries. The New Asia and Select World
Funds also have substantial exposure to these risks because these Funds may
invest a significant portion of their assets in emerging market securities. In
addition, risks associated with investing in a narrowly defined geographic area
(discussed above under "Foreign (non-U.S.) Investment Risk") are more pronounced
for the Funds that invest in emerging markets.

Currency Risk

Funds that invest directly in foreign currencies or in securities that trade in,
and receive revenues in, foreign currencies are subject to the risk that those
currencies will decline in value relative to the U.S. Dollar, or, in the case of
hedging positions,

                                       24
<PAGE>

that the U.S. Dollar will decline in value relative to the currency being
hedged. The New Asia, Europe Growth, Select World and Emerging Markets Funds are
particularly sensitive to currency risk. Currency rates in foreign countries may
fluctuate significantly over short periods of time for a number of reasons,
including changes in interest rates, intervention (or the failure to intervene)
by U.S. or foreign governments, central banks or supranational entities such as
the International Monetary Fund, or by the imposition of currency controls or
other political developments in the U.S. or abroad.

Focused Investment Risk

Focusing Fund investments in a small number of issuers, industries or foreign
currencies increases risk. Funds, such as the Select World Fund, that invest in
a relatively small number of issuers may have more risk because changes in the
value of a single security or the impact of a single economic, political or
regulatory occurrence may have a greater adverse impact on the Fund's net asset
value. Some of those issuers also may present substantial credit or other risks.
The New Asia, Europe Growth, Select World and Emerging Markets Funds may be
subject to increased risk to the extent that they focus their investments in
securities denominated in a particular foreign currency or in a narrowly defined
geographic area outside the U.S. The Internet Innovation, Electronics Innovation
and Small-Cap Technology Funds are subject to risks prevalent in the Internet,
electronics and technology sectors, respectively, such as the risks of rapid
obsolescence of products and services, significant losses, increased volatility
of these companies' securities and limited operating histories, because they
"concentrate" their investments in those sectors. Similarly, the Telecom
Innovation and Healthcare Innovation Funds "concentrate" their investments in
the telecommunications and health care industries, respectively, and therefore
are subject to the risks particular to those industries, such as the risks
associated with additional government regulation of the telecommunications and
health care industries or changes to existing regulations and government subsidy
levels. Also, the Funds may from time to time have greater risk to the extent
they invest a substantial portion of their assets in related industries such as
"technology" or "financial and business services," which may share common
characteristics and react similarly to market developments.

Leveraging Risk

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

Interest Rate Risk

To the extent that Funds purchase fixed income securities for investment or
defensive purposes, they will be subject to interest rate risk, a market risk
relating to investments in fixed income securities such as bonds and notes. As
interest rates rise, the value of fixed income securities in a Fund's portfolio
are likely to decrease. Securities with longer "durations" (defined below) tend
to be more sensitive to changes in interest rates, usually making them more
volatile than securities with shorter durations. Duration is a measure of the
expected life of a fixed income security that is used to determine the
sensitivity of a security's price to changes in interest rates. A Fund with a
longer average portfolio duration will be more sensitive to changes in interest
rates than a Fund with a shorter average portfolio duration.

Credit Risk

All of the Funds are subject to credit risk. This is the risk that the issuer or
the guarantor of a fixed income security, or the counterparty to a derivatives
contract, repurchase agreement or a loan of portfolio securities, is unable or
unwilling to make timely principal and/or interest payments, or to otherwise
honor its obligations. Securities are subject to varying degrees of credit risk,
which are often reflected in their credit ratings.

Management Risk

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

Management of the Funds

Investment Adviser and Administrator

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

PIMCO Advisors is located at 800 Newport Center Drive, Newport Beach, California
92660. Organized in 1987, PIMCO Advisors provides investment management and
advisory services to private accounts of institutional and individual clients
and to mutual funds. As of March 31, 2000, PIMCO Advisors and its subsidiary
partnerships had more than $264 billion in assets under management.


PIMCO Advisors has retained its subsidiary PIMCO/Allianz International Advisors
LLC to manage the investments of the New Asia, Europe Growth, Select World and
Emerging Markets Funds The PIMCO Equity Advisors division of PIMCO Advisors
manages the investments of the Healthcare Innovation, Internet Innovation,
Small-Cap Technology, Telecom Innovation and Electronics Innovation Funds (PIMCO
Equity Advisors and PIMCO/Allianz International Advisors LLC are each referred
to as a "Sub-Adviser" in this prospectus). See "Sub-Advisers" below.

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

Advisory Fees

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

The Funds will pay monthly advisory fees to PIMCO Advisors at the following
annual rates (stated as a percentage of the average daily net assets of each
Fund taken separately):

Administrative Fees

Each Fund pays for the administrative services it requires under a fee structure
which is essentially fixed.  Institutional and Administrative Class shareholders
of each Fund pay an administrative fee to PIMCO Advisors, computed as a
percentage of the Fund's assets attributable in the aggregate to those classes
of shares.  PIMCO Advisors, in turn, provides or procures administrative
services for Institutional and Administrative Class shareholders and also bears
the costs of various third-party services required by the Funds, including
audit, custodial, portfolio accounting, legal, transfer agency and printing
costs. The result of this fee structure is an expense level for Institutional
and

                                       26

Administrative Class shareholders of each Fund that, with limited exceptions, is
precise and predictable under ordinary circumstances.

Institutional and Administrative Class shareholders of the Funds will pay PIMCO
Advisors monthly administrative fees at the following annual rates (stated as a

Investment Options -
Institutional Class and Administrative Class Shares

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

The Trust does not charge any sales charges (loads) or other fees in connection
with purchases, sales (redemptions) or exchanges of Institutional Class or
Administrative Class shares.

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

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

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

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

Arrangements with Service Agents.  Institutional Class and Administrative Class
shares of the Funds may be offered through certain brokers and financial
intermediaries ("service agents") that have established a shareholder
servicing relationship with the Trust on behalf of their customers. The Trust
pays no compensation to such entities other than service and/or distribution
fees paid with respect to Administrative Class shares. Service agents may impose
additional or different conditions than the Trust on purchases, redemptions or
exchanges of Fund shares by their customers. Service agents may also
independently establish and charge their customers transaction fees, account
fees and other amounts in connection with purchases, sales and redemptions of
Fund shares in addition to any fees charged by the Trust. These additional fees
may vary over time and would increase the cost of the customer's investment and
lower investment returns. Each service agent is responsible for transmitting to
its customers a schedule of any such fees and information regarding any
additional or different conditions regarding purchases, redemptions and
exchanges. Shareholders who are customers of service agents should consult their
service agents for information regarding these fees and conditions.

                                       30

Purchases, Redemptions and Exchanges

Purchasing Shares

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

Institutional Class shares are offered primarily for direct investment by
investors such as pension and profit sharing plans, employee benefit trusts,
endowments, foundations, corporations and high net worth individuals.
Institutional Class shares may also be offered through certain financial
intermediaries that charge their customers transaction or other fees with
respect to their customers' investments in the Funds.

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

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

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

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

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

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

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

Except as described below, an investor may purchase Institutional Class and
Administrative Class shares only by wiring federal funds to the Transfer Agent,
National Financial Data Services, 330 West 9th Street, 4th Floor, Kansas City,
Missouri

                                       31
<PAGE>

64105. Before wiring federal funds, the investor must telephone the Trust at 1-
800-927-4648 to receive instructions for wire transfer and must provide the
following information: name of authorized person, shareholder name, shareholder
account number, name of Fund and share class, amount being wired, and wiring
bank name.

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

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

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

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

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

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

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

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

Redeeming Shares

Redemptions by Mail.  An investor may redeem (sell) Institutional Class and
Administrative Class shares by submitting a written request to PIMCO Funds at
840 Newport Center Drive, Suite 300, Newport Beach, California 92660. The
redemption

                                       32
<PAGE>

request should state the Fund from which the shares are to be redeemed, the
class of shares, the number or dollar amount of the shares to be redeemed and
the account number. The request must be signed exactly as the names of the
registered owners appear on the Trust's account records, and the request must be
signed by the minimum number of persons designated on the Client Registration
Application that are required to effect a redemption.

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

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

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

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

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

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

For shareholder protection, a request to change information contained in an
account registration (for example, a request to change the bank designated to
receive wire redemption proceeds) must be received in writing, signed by the
minimum number of persons designated on the Client Registration Application that
are required to effect a redemption, and accompanied by a signature guarantee
from any eligible guarantor institution, as determined in accordance with the
Trust's

                                       33
<PAGE>

procedures. Shareholders should inquire as to whether a particular institution
is an eligible guarantor institution. A signature guarantee cannot be provided
by a notary public. In addition, corporations, trusts, and other institutional
organizations are required to furnish evidence of the authority of the persons
designated on the Client Registration Application to effect transactions for the
organization.

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

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

Redemptions of Fund shares may be suspended when trading on the New York Stock
Exchange is restricted or during an emergency which makes it impracticable for
the Funds to dispose of their securities or to determine fairly the value of
their net assets, or during any other period as permitted by the Securities and
Exchange Commission for the protection of investors. Under these and other
unusual circumstances, the Trust may suspend redemptions or postpone payment for
more than seven days, as permitted by law.

Exchange Privilege

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

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

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

How Fund Shares Are Priced

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

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

Investments initially valued in currencies other than the U.S. dollar are
converted to U.S. dollars using exchange rates obtained from pricing services.
As a result, the NAV of a Fund's shares may be affected by changes in the value
of currencies in relation to the U.S. dollar. The value of securities traded in
markets outside the United States or denominated in currencies other than the
U.S. dollar may be affected significantly on a day that the New York Stock
Exchange is closed and an investor is not able to purchase, redeem or exchange
shares. In particular, calculation of the NAV of the New Asia, Europe Growth,
Select World and Emerging Markets Funds may not take place contemporaneously
with the determination of the prices of foreign securities used in NAV
calculations.

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

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

Under certain circumstances, the per share NAV of the Administrative Class
shares of the Funds may be lower than the per share NAV of the Institutional
Class shares as a result of the daily expense accruals of the service and/or
distribution fees paid by Administrative Class shares. Generally, for Funds that
pay income dividends, those dividends are expected to differ over time by
approximately the amount of the expense accrual differential between the two
classes.

Fund Distributions

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

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

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

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

Tax Consequences

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

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

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

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

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

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

Characteristics and Risks of Securities
and Investment Techniques

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

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

The Healthcare Innovation, Internet Innovation, Small-Cap Technology, Telecom
Innovation, Electronics Innovation, New Asia, Europe Growth, Select World and
Emerging Markets Funds will each invest primarily in common stocks, and may also
invest in other kinds of equity securities, including preferred stocks and
securities (including fixed income securities and warrants) convertible into or
exercisable for common stocks. Each of these Funds may invest a portion of their
assets in fixed income securities. The Funds may temporarily hold up to 100% of
their assets in short-term U.S. Government securities and other money market
instruments for defensive purposes in response to unfavorable market and other
conditions. The New Asia, Europe Growth, Select World and Emerging Markets Funds
may also hold up to 100% of their assets in other domestic fixed income, foreign
fixed income and equity securities principally traded in the U.S., including
obligations issued or guaranteed by a foreign government or its agencies,
authorities or instrumentalities, corporate bonds and American Depository
Receipts, for temporary defensive purposes.

The temporary defensive strategies described in this section would be
inconsistent with the investment objective and principal investment strategies
of each of the noted Funds and may adversely affect the Fund's ability to
achieve its investment objective.

Companies With Smaller Market Capitalizations

Each of the Funds may invest in securities of companies with market
capitalizations that are small compared to other publicly traded companies. The
Small-Cap Technology Fund invests primarily in smaller companies and is
especially sensitive to the risks described below. In addition, the Healthcare
Innovation, Internet Innovation, Telecom Innovation, Electronics Innovation, New
Asia, Europe Growth, Select World and Emerging Markets Funds generally have
significant exposure to these risks.

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

                                       37
<PAGE>

interest in their securities as compared to larger companies, and it may take
longer for the prices of the securities to reflect the full value of a company's
earnings potential or assets.

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

The Funds may purchase securities in initial public offerings (IPOs). These
securities are subject to many of the same risks of investing in companies with
smaller market capitalizations. Securities issued in IPOs have no trading
history, and information about the companies may be available for very limited
periods. In addition, the prices of securities sold in IPOs may be highly
volatile. A Fund may not be able to invest in securities issued in IPOs to the
extent desired because, for example, only a small portion of the securities
being offered in an IPO may be made available to the Fund or because under
certain market conditions few companies may issue securities in IPOs.

Foreign Securities
The New Asia, Europe Growth, Select World and Emerging Markets Funds normally
invest principally in securities of foreign issuers, securities traded
principally in securities markets outside the United States and/or securities
denominated in foreign currencies (together, "foreign securities"). The
Healthcare Innovation, Internet Innovation, Small-Cap Technology, Telecom
Innovation and Electronics Innovation Funds may invest up to 15% of their
respective assets in foreign securities.

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

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

Emerging Market Securities

The Funds may invest in securities of issuers based in or that trade principally
in countries with developing (or "emerging market") economies.  The Emerging
Markets Fund is particularly susceptible to these risks because it invests
principally in companies located in emerging market countries.  The New Asia and
Select World Funds also have substantial exposure to these risks because these
Funds may invest significant portions of their assets in emerging market
securities. Investing in emerging market securities imposes risks different
from, or greater than, risks of investing in domestic securities or in foreign,
developed countries. These risks include: smaller market capitalization of
securities markets, which may suffer periods of relative illiquidity;
significant price volatility; restrictions on foreign investment; and possible
repatriation of investment income and capital. In addition, foreign investors
may be required to register the proceeds of sales, and future

                                       38
<PAGE>

economic or political crises could lead to price controls, forced mergers,
expropriation or confiscatory taxation, seizure, nationalization or the creation
of government monopolies. The currencies of emerging market countries may
experience significant declines against the U.S. dollar, and devaluation may
occur subsequent to investments in these currencies by a Fund. Inflation and
rapid fluctuations in inflation rates have had, and may continue to have,
negative effects on the economies and securities markets of certain emerging
market countries.

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

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

Foreign Currencies

A Fund that invests directly in foreign currencies or in securities that trade
in, and receive revenues in, foreign currencies will be subject to currency
risk. The New Asia, Europe Growth, Select World and Emerging Markets Funds are
particularly sensitive to this risk.

Foreign currency exchange rates may fluctuate significantly over short periods
of time. They generally are determined by supply and demand and the relative
merits of investments in different countries, actual or perceived changes in
interest rates and other complex factors. Currency exchange rates also can be
affected unpredictably by intervention (or the failure to intervene) by U.S. or
foreign governments or central banks, or by currency controls or political
developments. For example, significant uncertainty surrounds the recent
introduction of the euro (a common currency unit for the European Union) in
January 1999 and the effect it may have on the value of securities denominated
in local European currencies.  The Europe Growth Fund is especially susceptible
to risks associated with the introduction of the Euro because it invests
principally in European companies, many of which are located in European
Monetary Union countries.  The Euro and other currencies in which the Funds'
assets are denominated may be devalued against the U.S. dollar, resulting in a
loss to the Funds.

Foreign Currency Transactions. The Funds may enter into forward foreign currency
exchange contracts to reduce the risks of adverse changes in foreign exchange
rates. In addition, the Funds may buy and sell foreign currency futures
contracts and options on foreign currencies and foreign currency futures. A
forward foreign currency exchange contract, which involves an obligation to
purchase or sell a specific currency at a future date at a price set at the time
of the contract, reduces a Fund's exposure to changes in the value of the
currency it will deliver and increases its exposure to changes in the value of
the currency it will receive for the duration of the contract. The effect on the
value of a Fund is similar to selling securities denominated in one currency and
purchasing securities denominated in another currency. Contracts to sell foreign
currency would limit any potential gain which might be realized by a Fund if the
value of the hedged currency increases. A Fund may enter into these contracts to
hedge against foreign exchange risk arising from the Fund's investment or
anticipated investment in securities denominated in foreign currencies. Suitable
hedging transactions may not be available in all circumstances and there can be
no assurance that a Fund will engage in such transactions at any given time or
from time to time. Also, such

                                       39
<PAGE>

transactions may not be successful and may eliminate any chance for a Fund to
benefit from favorable fluctuations in relevant foreign currencies.

The New Asia, Europe Growth, Select World and Emerging Markets Funds may also
enter into these contracts for purposes of increasing exposure to a foreign
currency or to shift exposure to foreign currency fluctuations from one currency
to another. To the extent that it does so, a Fund will be subject to the
additional risk that the relative value of currencies will be different than
anticipated by the Fund's portfolio manager. The Funds may use one currency (or
a basket of currencies) to hedge against adverse changes in the value of another
currency (or a basket of currencies) when exchange rates between the two
currencies are positively correlated. Each Fund will segregate assets determined
to be liquid by PIMCO Advisors or a Sub-Adviser in accordance with procedures
established by the Board of Trustees to cover its obligations under forward
foreign currency exchange contracts entered into for non-hedging purposes.

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

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

Derivatives
Each Fund may, but is not required to, use a number of derivative instruments
for risk management purposes or as part of its investment strategies. Generally,
derivatives are financial contracts whose value depends upon, or is derived
from, the value of an underlying asset, reference rate or index, and may relate
to stocks, bonds, interest rates, currencies or currency exchange rates,
commodities, and related indexes. A portfolio manager may decide not to employ
any of these strategies and there is no assurance that any derivatives strategy
used by a Fund will succeed.

Examples of derivative instruments include options contracts, futures contracts,
options on futures contracts and swap agreements. The Funds may purchase and
sell (write) call and put options on securities, securities indexes and foreign
currencies. Each Fund may purchase and sell futures contracts and options
thereon with respect to securities, securities indexes and foreign currencies.
A description of these and other derivative instruments that the Funds may use
are described under "Investment Objectives and Policies" in the Statement of
Additional Information.

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

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

                                       40
<PAGE>

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

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

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

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

Market and Other Risks  Like most other investments, derivative instruments are
subject to the risk that the market value of the instrument will change in a way
detrimental to a Fund's interest. If a portfolio manager incorrectly forecasts
the values of securities, currencies or interest rates or other economic factors
in using derivatives for a Fund, the Fund might have been in a better position
if it had not entered into the transaction at all. While some strategies
involving derivative instruments can reduce the risk of loss, they can also
reduce the opportunity for gain or even result in losses by offsetting favorable
price movements in other Fund investments. A Fund may also have to buy or sell a
security at a disadvantageous time or price because the Fund is legally required
to maintain offsetting positions or asset coverage in connection with certain
derivatives transactions.

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

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

Credit Ratings and Unrated Securities
The Funds may invest in securities based on their credit ratings assigned by
rating agencies such as Moody's Investors Service, Inc. ("Moody's") and
Standard & Poor's Ratings Services ("S&P"). Moody's, S&P and other rating
agencies are private services that provide ratings of the credit quality of
fixed income securities, including convertible securities. The Appendix to the
Statement of Additional Information describes the various ratings assigned to
fixed income securities by Moody's and S&P. Ratings assigned by a rating agency
are not absolute standards of credit quality and do not evaluate

                                       41
<PAGE>

market risk. Rating agencies may fail to make timely changes in credit ratings
and an issuer's current financial condition may be better or worse than a rating
indicates. A Fund will not necessarily sell a security when its rating is
reduced below its rating at the time of purchase. PIMCO Advisors and the Sub-
Advisers do not rely solely on credit ratings, and develop their own analysis of
issuer credit quality.

A Fund may purchase unrated securities (which are not rated by a rating agency)
if its portfolio manager determines that the security is of comparable quality
to a rated security that the Fund may purchase. Unrated securities may be less
liquid than comparable rated securities and involve the risk that the portfolio
manager may not accurately evaluate the security's comparative credit rating.

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

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

Short Sales
Each Fund may make short sales as part of its overall portfolio management
strategies or to offset a potential decline in the value of a security. A short
sale involves the sale of a security that is borrowed from a broker or other
institution to complete the sale. A Fund may only enter into short selling
transactions if the security sold short is held in the Fund's portfolio or if
the Fund has the right to acquire the security without the payment of further
consideration. For these purposes, a Fund may also hold or have the right to
acquire securities which, without the payment of any further consideration, are
convertible into or exchangeable for the securities sold short. Short sales
expose a Fund to the risk that it will be required to acquire, convert or
exchange securities to replace the borrowed securities (also known as
"covering" the short position) at a time when the securities sold short have
appreciated in value, thus resulting in a loss to the Fund.

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

Repurchase Agreements
Each Fund may enter into repurchase agreements, in which the Fund purchases a
security from a bank or broker-dealer that agrees to repurchase the security at
the Fund's cost plus interest within a specified time. If the party agreeing to
repurchase should default, the Fund will seek to sell the securities which it
holds. This could involve procedural costs or delays in addition to a loss on
the securities if their value should fall below their repurchase price. Those
Funds whose investment objectives do not include the earning of income will
invest in repurchase agreements only as a cash management technique

                                       42
<PAGE>

with respect to that portion of its portfolio maintained in cash. Repurchase
agreements maturing in more than seven days are considered illiquid securities.


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

Illiquid Securities
Each Fund may invest in securities that are illiquid so long as not more than
15% of the value of the Fund's net assets (taken at market value at the time of
investment) would be invested in such securities. Certain illiquid securities
may require pricing at fair value as determined in good faith under the
supervision of the Board of Trustees. A portfolio manager may be subject to
significant delays in disposing of illiquid securities held by the Fund, and
transactions in illiquid securities may entail registration expenses and other
transaction costs that are higher than those for transactions in liquid
securities. The term "illiquid securities" for this purpose means securities
that cannot be disposed of within seven days in the ordinary course of business
at approximately the amount at which a Fund has valued the securities. Please
see "Investment Objectives and Policies" in the Statement of Additional
Information for a listing of various securities that are generally considered to
be illiquid for these purposes. Restricted securities, i.e., securities subject
to legal or contractual restrictions on resale, may be illiquid. However, some
restricted securities (such as securities issued pursuant to Rule 144A under the
Securities Act of 1933 and certain commercial paper) may be treated as liquid,
although they may be less liquid than registered securities traded on
established secondary markets.

Investment in Other Investment Companies
The New Asia, Europe Growth, Select World and Emerging Markets Funds may invest
up to [10%] of their assets in securities of other investment companies, such as
closed-end management investment companies, or in pooled accounts or other
investment vehicles which invest in foreign markets.  The Healthcare Innovation,
Internet Innovation, Small-Cap Technology, Telecom Innovation and Electronics
Innovation Funds may invest up to 5% of their assets in such securities.  As a
shareholder of an investment company, a Fund may indirectly bear service and
other fees which are in addition to the fees the Fund pays its service
providers.

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

Changes in Investment Objectives and Policies
The investment objective of each Fund described in this Prospectus may be
changed by the Board of Trustees without shareholder approval. Unless otherwise
stated in the Statement of Additional Information, all investment policies of
the Funds may be changed by the Board of Trustees without shareholder approval.
If there is a change in a Fund's investment objective or policies, including a
change approved by shareholder vote, shareholders should consider whether the
Fund remains an appropriate investment in light of their then current financial
position and needs.

New Funds
In addition to the risks described under "Summary of Principal Risks" above
and in this section, the Funds are newly formed and therefore have no history
upon which investors can evaluate their likely performance. Accordingly, there
can be no

                                       43
<PAGE>

assurance that the Funds will achieve their investment objective. Also, it is
possible that the Funds may invest in securities offered in initial public
offerings and other similar transactions which, because of each Fund's size, may
have a disproportionate impact on each Fund's performance results. The Funds
would not necessarily have achieved the same performance results if their
aggregate net assets had been greater.

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

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

     The Fund seeks to achieve its investment objective by normally investing at
least 65% of its assets in securities of companies principally engaged in the
design, manufacture or sale of new, creative or different, or " innovative,"
products or services used for or in connection with health care or medicine.
These companies may include, for example, pharmaceutical companies, companies
involved in biotechnology, medical diagnostic, biochemical or other health care
research and development, companies involved in the operation of health care
facilities, and other companies involved in the design, manufacture or sale of
health care-related products or services such as medical, dental and optical
products, hardware or services.  Although the Fund emphasizes companies which
utilize health care technologies, it is not required to invest exclusively in a
particular business sector or industry, and at any time may not be invested in
any of the industry sectors listed above.

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

     Although the Fund invests principally in common stocks, the Fund may also
invest in other types of equity securities, including preferred stocks and
convertible securities.  The Fund may invest up to 15% of its assets in foreign
securities, usually in the form of American Depository Receipts.

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

</TABLE>

              (1)  The Fund's administration agreement includes a plan for Class
                   D shares that has been adopted in conformity with the
                   requirements set forth in Rule 12b-1 under the Investment
                   Company Act of 1940. Up to 0.25% per year of the total
                   Administrative Fee paid under the administration agreement
                   may be Distribution and/or Service (12b-1) Fees. The Fund
                   will pay a total of [0.85%] per year under the administration
                   agreement regardless of whether a portion or none of the
                   [0.25%] authorized under the plan is paid under the plan.
                   Please see "Management of the Funds - Administrative Fees"
                   for details. The Fund intends to treat any fees paid under
                   the plan as "service fees" for purposes of applicable rules
                   of the National Association of Securities Dealers, Inc. (the
                   "NASD"). To the extent that such fees are deemed not to be
                   "service fees", Class D shareholders may, depending on the
                   length of time the shares are held, pay more than the
                   economic equivalent of the maximum front-end sales charges
                   permitted by relevant rules of the NASD.

               (2) Other Expenses, which is based on estimated amounts for the
                   Fund's initial fiscal year, reflects the portion of the
                   Administrative Fee paid by the class that is not reflected
                   under Distribution and/or Service (12b-1) Fees, and [0.04%]
                   representing the Fund's organizational expenses as attributed
                   to the class ("Organizational Expenses").

               (3) Net Expenses reflect the effect of a contractual agreement by
                   PIMCO Advisors to waive, reduce or reimburse its
                   Administrative Fee for Class D shares in an amount that, in
                   essence, is equal to the Fund's Organizational Expenses
                   attributed to the class. Because the Organizational Expenses
                   will all be accounted for in the Fund's initial fiscal year,
                   the Fund's reasonable expectation is that the relevant
                   conditions will not continue after the Fund's fiscal year
                   ending June 30, 2001.

               Examples. The Examples below are intended to help you compare the
               cost of investing in Institutional Class or Administrative Class
               shares of the Fund with the costs of investing in other mutual
               funds. The Examples assume that you invest $10,000 in the noted
               class of shares for the time periods indicated, and then redeem
               all your shares at the end of those periods. The Examples also
               assume that your investment has a 5% return each year, the
               reinvestment of all dividends and distributions, and the Fund's
               operating expenses remain the same. Although your actual costs
               may be higher or lower, the Examples show what your costs would
               be based on these assumptions./(1)/

     The Fund seeks to achieve its investment objective by normally investing at
least 65% of its assets in common stocks of companies that derive at least 50%
of their revenues, expenses or profits from the research, design, development,
manufacturing or distribution of new, creative or different, or "innovative,"
products, processes or services for use with Internet- or Internet-related
businesses.  Some examples of these companies may include, for example,
providers of broad-band Internet access, web site content, Internet software and
electronic commerce.  Although the Fund emphasizes Internet-related companies,
it is not required to invest exclusively in a particular business sector or
industry, and at any time may not be invested in any of the industry sectors

                   Administrative Fee for Class D shares in an amount that, in
                   essence, is equal to the Fund's Organizational Expenses
                   attributed to the class. Because the Organizational Expenses
                   will all be accounted for in the Fund's initial fiscal year,
                   the Fund's reasonable expectation is that the relevant
                   conditions will not continue after the Fund's fiscal year
                   ending June 30, 2001.

               Examples. The Examples below are intended to help you compare the
               cost of investing in Institutional Class or Administrative Class
               shares of the Fund with the costs of investing in other mutual
               funds. The Examples assume that you invest $10,000 in the noted
               class of shares for the time periods indicated, and then redeem
               all your shares at the end of those periods. The Examples also
               assume that your investment has a 5% return each year, the
               reinvestment of all dividends and distributions, and the Fund's
               operating expenses remain the same. Although your actual costs
               may be higher or lower, the Examples show what your costs would
               be based on these assumptions./(1)/

     The Fund seeks to achieve its investment objective by normally investing at
least 65% of its assets in common stocks of technology and technology-related
companies with market capitalizations of between $100 million and $2 billion at
the time of investment. The Fund identifies its investment universe of
technology-related companies primarily by reference to classifications made by
independent firms, such as Standard & Poor's (for example, companies classified
as "Information Technology" companies), and by identifying companies that
derive a substantial portion of their revenues from the manufacture, sale and/or
service of technological products. Although the Fund emphasizes companies which
utilize technologies, it is not required to invest exclusively in a particular
business sector or industry.

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

     Although the Fund invests principally in common stocks, the Fund may also
invest in other types of equity securities, including preferred stocks and
convertible securities.  The Fund may invest up to 15% of its assets in foreign
securities, usually in the form of American Depository Receipts.

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

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

</TABLE>

              (1)  The Fund's administration agreement includes a plan for Class
                   D shares that has been adopted in conformity with the
                   requirements set forth in Rule 12b-1 under the Investment
                   Company Act of 1940. Up to 0.25% per year of the total
                   Administrative Fee paid under the administration agreement
                   may be Distribution and/or Service (12b-1) Fees. The Fund
                   will pay a total of [0.85%] per year under the administration
                   agreement regardless of whether a portion or none of the
                   [0.25%] authorized under the plan is paid under the plan.
                   Please see "Management of the Funds - Administrative Fees"
                   for details. The Fund intends to treat any fees paid under
                   the plan as "service fees" for purposes of applicable rules
                   of the National Association of Securities Dealers, Inc. (the
                   "NASD"). To the extent that such fees are deemed not to be
                   "service fees", Class D shareholders may, depending on the
                   length of time the shares are held, pay more than the
                   economic equivalent of the maximum front-end sales charges
                   permitted by relevant rules of the NASD.

               (2) Other Expenses, which is based on estimated amounts for the
                   Fund's initial fiscal year, reflects the portion of the
                   Administrative Fee paid by the class that is not reflected
                   under Distribution and/or Service (12b-1) Fees, and [0.04%]
                   representing the Fund's organizational expenses as attributed
                   to the class ("Organizational Expenses").

               (3) Net Expenses reflect the effect of a contractual agreement by
                   PIMCO Advisors to waive, reduce or reimburse its
                   Administrative Fee for Class D shares in an amount that, in
                   essence, is equal to the Fund's Organizational Expenses
                   attributed to the class. Because the Organizational Expenses
                   will all be accounted for in the Fund's initial fiscal year,
                   the Fund's reasonable expectation is that the relevant
                   conditions will not continue after the Fund's fiscal year
                   ending June 30, 2001.

               Examples. The Examples below are intended to help you compare the
               cost of investing in Institutional Class or Administrative Class
               shares of the Fund with the costs of investing in other mutual

     The Fund seeks to achieve its investment objective by normally investing at
least 65% of its assets in common stocks of companies principally engaged in the
development, manufacture or sale of new, creative or different, or "innovative,"
communications services or communications equipment. These companies may
include, for example, companies that provide traditional local and long-distance
telephone service or equipment, companies that provide cellular, paging, local
and wide area product networks or equipment, companies that provide satellite,
microwave and cable television or equipment, and companies involved in new
technologies such as fiber optics, semiconductors and data transmission.
Although the Fund emphasizes telecommunications-related companies, it is not
required to invest exclusively in a particular business sector or industry, and
at any time may not be invested in any of the industry sectors listed above.

     The portfolio manager selects stocks for the Fund using a "growth" style.

                    by PIMCO Advisors to waive, reduce or reimburse its
                    Administrative Fee for Class D shares in an amount that, in
                    essence, is equal to the Fund's Organizational Expenses
                    attributed to the class. Because the Organizational Expenses
                    will all be accounted for in the Fund's initial fiscal year,
                    the Fund's reasonable expectation is that the relevant
                    conditions will not continue after the Fund's fiscal year
                    ending June 30, 2001.

               Examples. The Examples below are intended to help you compare the
               cost of investing in Institutional Class or Administrative Class
               shares of the Fund with the costs of investing in other mutual
               funds. The Examples assume that you invest $10,000 in the noted
               class of shares for the time periods indicated, and then redeem
               all your shares at the end of those periods. The Examples also
               assume that your investment has a 5% return each year, the
               reinvestment of all dividends and distributions, and the Fund's
               operating expenses remain the same. Although your actual costs
               may be higher or lower, the Examples show what your costs would
               be based on these assumptions./(1)/

     The Fund seeks to achieve its investment objective by normally investing at
least 65% of its assets in common stocks of companies principally engaged in the
development, manufacture or sale of new, creative or different, or "innovative,"
electronics products and services. These companies may include, for example,
companies engaged in the development, manufacture, sale or service of electronic
components, equipment vendors to electronics manufacturers, electronic component
distributors, electronic instruments and systems vendors, and companies that
provide electronics-related services. Although the Fund emphasizes companies in
the electronics industry, it is not required to invest exclusively in a
particular business sector or industry, and at any time may not be invested in
any of the types of companies listed above.

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

     Although the Fund invests principally in common stocks, the Fund may also
invest in other types of equity securities, including preferred stocks and
convertible securities. The Fund may invest up to 15% of its assets in foreign
securities, usually in the form of American Depository Receipts.

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

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

</TABLE>

               (1)  The Fund's administration agreement includes a plan for
                    Class D shares that has been adopted in conformity with the
                    requirements set forth in Rule 12b-1 under the Investment
                    Company Act of 1940. Up to 0.25% per year of the total
                    Administrative Fee paid under the administration agreement
                    may be Distribution and/or Service (12b-1) Fees. The Fund
                    will pay a total of [0.85%] per year under the
                    administration agreement regardless of whether a portion or
                    none of the [0.25%] authorized under the plan is paid under
                    the plan. Please see "Management of the Funds -
                    Administrative Fees" for details. The Fund intends to treat
                    any fees paid under the plan as "service fees" for purposes
                    of applicable rules of the National Association of
                    Securities Dealers, Inc. (the "NASD"). To the extent that
                    such fees are deemed not to be "service fees", Class D
                    shareholders may, depending on the length of time the shares
                    are held, pay more than the economic equivalent of the
                    maximum front-end sales charges permitted by relevant rules
                    of the NASD.

               (2)  Other Expenses, which is based on estimated amounts for the
                    Fund's initial fiscal year, reflects the portion of the
                    Administrative Fee paid by the class that is not reflected
                    under Distribution and/or Service (12b-1) Fees, and [0.04%]
                    representing the Fund's organizational expenses as

               (3)  Net Expenses reflect the effect of a contractual agreement
                    by PIMCO Advisors to waive, reduce or reimburse its
                    Administrative Fee for Class D shares in an amount that, in
                    essence, is equal to the Fund's Organizational Expenses
                    attributed to the class. Because the Organizational Expenses
                    will all be accounted for in the Fund's initial fiscal year,
                    the Fund's reasonable expectation is that the relevant
                    conditions will not continue after the Fund's fiscal year

     The Fund seeks to achieve its investment objective by normally investing at
least 65% of its assets in an international portfolio of common stocks and other
equity securities of companies located in Asia. The Fund will primarily invest
in securities of companies located in the Far East, including Australia, China,
Hong Kong, Japan, Indonesia, India, Malaysia, New Zealand, the Philippines,
Singapore, South Korea, Taiwan and Thailand, although the Fund will not
necessarily be invested in all of these countries at any time. The Fund may also
invest in securities of foreign issuers traded on U.S. securities markets, but
will normally not invest in U.S. issuers. However, the Fund has no prescribed
limits on geographic asset distribution and may invest in any foreign securities
market in the world. The Fund invests most of its assets in foreign securities
which trade in currencies other than the U.S. dollar and may invest directly in
foreign currencies.

     The portfolio manager selects securities for the Fund using the Sub-
Adviser's "Growth at a Reasonable Price" (GARP) investment style. The GARP style
uses a research-driven "bottom-up" approach that seeks to identify companies
with above-average long-term growth prospects and attractive valuations and that
possess a sustainable competitive advantage, such as superior or innovative
products, personnel and distribution systems. In selecting stocks, the portfolio
manager analyzes a broad range of company fundamentals, such as long-term growth
prospects, price-to-earnings ratios and other valuation measures, dividend and
profit growth, balance sheet strength and return on assets. A stock's liquidity
and volatility are also considered. The portfolio manager sells stocks in order
to adjust or rebalance the Fund's portfolio and to replace companies with
weakening fundamentals.

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

                    essence, is equal to the Fund's Organizational Expenses
                    attributed to the class. Because the Organizational Expenses
                    will all be accounted for in the Fund's initial fiscal year,
                    the Fund's reasonable expectation is that the relevant
                    conditions will not continue after the Fund's fiscal year
                    ending June 30, 2001.

               Examples. The Examples below are intended to help you compare the
               cost of investing in Institutional Class or Administrative Class
               shares of the Fund with the costs of investing in other mutual
               funds. The Examples assume that you invest $10,000 in the noted
               class of shares for the time periods indicated, and then redeem
               all your shares at the end of those periods. The Examples also
               assume that your investment has a 5% return each year, the
               reinvestment of all dividends and distributions, and the Fund's
               operating expenses remain the same. Although your actual costs
               may be higher or lower, the Examples show what your costs would
               be based on these assumptions./(1)/

     The Fund seeks to achieve its investment objective by normally investing at
least 65% of its assets in an international portfolio of common stocks and other
equity securities of European companies with medium and large market
capitalizations. The Fund may also invest in securities of foreign issuers
traded on U.S. securities markets, but will normally not invest in U.S. issuers.
However, the Fund has no prescribed limits on geographic asset distribution and
may invest in any foreign securities market in the world. The Fund invests most
of its assets in foreign securities which trade in currencies other than the
U.S. dollar (e.g., the euro) and may invest directly in foreign currencies.

     The portfolio manager selects securities for the Fund using the Sub-
Adviser's "Growth at a Reasonable Price" (GARP) investment style. The GARP style
uses a research-driven "bottom-up" approach that seeks to identify companies
with above-average long-term growth prospects and attractive valuations and that
possess a sustainable competitive advantage, such as superior or innovative
products, personnel and distribution systems. In selecting stocks, the portfolio
manager analyzes a broad range of company fundamentals, such as long-term growth
prospects, price-to-earnings ratios and other valuation measures, dividend and
profit growth, balance sheet strength and return on assets. A stock's liquidity
and volatility are also considered. The portfolio manager sells stocks in order
to adjust or rebalance the Fund's portfolio and to replace companies with
weakening fundamentals.

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

Principal Risks     Among the principal risks of investing in the Fund,

</TABLE>

                    (1)  The Fund's administration agreement includes a plan for
                         Class D shares that has been adopted in conformity with
                         the requirements set forth in Rule 12b-1 under the
                         Investment Company Act of 1940. Up to 0.25% per year of
                         the total Administrative Fee paid under the
                         administration agreement may be Distribution and/or
                         Service (12b-1) Fees. The Fund will pay a total of
                         [0.85%] per year under the administration agreement
                         regardless of whether a portion or none of the [0.25%]
                         authorized under the plan is paid under the plan.
                         Please see "Management of the Funds - Administrative
                         Fees" for details. The Fund intends to treat any fees
                         paid under the plan as "service fees" for purposes of
                         applicable rules of the National Association of
                         Securities Dealers, Inc. (the "NASD"). To the extent
                         that such fees are deemed not to be "service fees,"
                         Class D shareholders may, depending on the length of
                         time the shares are held, pay more than the economic
                         equivalent of the maximum front-end sales charges
                         permitted by relevant rules of the NASD.

                    (2)  Other Expenses, which is based on estimated amounts for
                         the Fund's initial fiscal year, reflects the portion of
                         the Administrative Fee paid by the class that is not
                         reflected under Distribution and/or Service (12b-1)
                         Fees, and [0.04%] representing the Fund's
                         organizational expenses as attributed to the class
                         ("Organizational Expenses").

                    (3)  Net Expenses reflect the effect of a contractual
                         agreement by PIMCO Advisors to waive, reduce or
                         reimburse its Administrative Fee for Class D shares in
                         an amount that, in essence, is equal to the Fund's
                         Organizational Expenses attributed to the class.
                         Because the Organizational Expenses will all be
                         accounted for in the Fund's initial fiscal year, the
                         Fund's reasonable expectation is that the relevant
                         conditions will not continue after the Fund's fiscal
                         year ending June 30, 2001.

                    Examples. The Examples below are intended to help you
                    compare the cost of investing in Institutional Class or
                    Administrative Class shares of the Fund with the costs of
                    investing in other mutual funds. The Examples assume that
                    you invest $10,000 in the noted class of shares for the time
                    periods indicated, and then redeem all your shares at the
                    end of those periods. The Examples also assume that your
                    investment has a 5% return each year, the reinvestment of
                    all dividends and distributions, and the Fund's operating
                    expenses remain the same. Although your actual costs may be
                    higher or lower, the Examples show what your costs would be
                    based on these assumptions.(1)

          The Fund seeks to achieve its investment objective by normally
investing at least 65% of its assets in an international portfolio of common
stocks and other equity securities of companies located throughout the world.
Although the Fund normally invests in issuers from at least five different
countries, including the United States, it may at times invest in fewer than
five countries, or even a single country. The Fund typically invests in
approximately 50 to 60 stocks, with each stock usually constituting from 1.25%
to 2.5% of the Fund's portfolio. The Fund may invest in both developed and
developing, or "emerging," markets. The Fund has no prescribed limits on
geographic asset distribution and may invest in any foreign securities market in
the world. The Fund invests most of its assets in foreign securities which trade
in currencies other than the U.S. dollar and may invest directly in foreign
currencies.

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

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

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

                    (2)  Other Expenses, which is based on estimated amounts for
                         the Fund's initial fiscal year, reflects the portion of
                         the Administrative Fee paid by the class that is not
                         reflected under Distribution and/or Service (12b-1)
                         Fees, and [0.04%] representing the Fund's
                         organizational expenses as attributed to the class
                         ("Organizational Expenses").

                    (3)  Net Expenses reflect the effect of a contractual
                         agreement by PIMCO Advisors to waive, reduce or
                         reimburse its Administrative Fee for Class D shares in
                         an amount that, in essence, is equal to the Fund's
                         Organizational Expenses attributed to the class.
                         Because the Organizational Expenses will all be
                         accounted for in the Fund's initial fiscal year, the
                         Fund's reasonable expectation is that the relevant
                         conditions will not continue after the Fund's fiscal
                         year ending June 30, 2001.

                    Examples. The Examples below are intended to help you
                    compare the cost of investing in Institutional Class or
                    Administrative Class shares of the Fund with the costs of
                    investing in other mutual funds. The Examples assume that
                    you invest $10,000 in the noted class of shares for the time
                    periods indicated, and then redeem all your shares at the
                    end of those periods. The Examples also assume that your
                    investment has a 5% return each year, the reinvestment of
                    all dividends and distributions, and the Fund's operating
                    expenses remain the same. Although your actual costs may be
                    higher or lower, the Examples show what your costs would be
                    based on these assumptions.(1)

          The Fund seeks to achieve its investment objective by normally
investing at least 65% of its assets in an international portfolio of common
stocks and equity securities of companies located in emerging market countries
within Europe, Asia, Latin America and Africa. The Fund may also invest in
securities of foreign issuers traded on U.S. securities markets, but will
normally not invest in U.S. issuers. However, the Fund has no prescribed limits
on geographic asset distribution and may invest in any foreign securities market
in the world. The Fund invests most of its assets in foreign securities which
trade in currencies other than the U.S. dollar and may invest directly in
foreign currencies.

          The portfolio manager selects securities for the Fund using the Sub-
Adviser's "Growth at a Reasonable Price" (GARP) investment style. The GARP style
uses a research-driven "bottom-up" approach that seeks to identify companies
with above-average long-term growth prospects and attractive valuations and that
possess a sustainable competitive advantage, such as superior or innovative
products, personnel and distribution systems. In selecting stocks, the portfolio
manager analyzes a broad range of company fundamentals, such as long-term growth
prospects, price-to-earnings ratios and other valuation measures, dividend and
profit growth, balance sheet strength and return on assets. A stock's liquidity
and volatility are also considered. The portfolio manager sells stocks in order
to adjust or rebalance the Fund's portfolio and to replace companies with
weakening fundamentals.

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

Summary of Principal Risks

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

Market Risk
The market price of securities owned by a Fund may go up or down, sometimes
rapidly or unpredictably. Each of the Funds normally invests most of its assets
in common stocks and/or other equity securities. A principal risk of investing
in each Fund is that the equity securities in its portfolio will decline in
value due to factors affecting equity securities markets generally or particular
industries represented in those markets. The values of equity securities may
decline due to general market conditions which are not specifically related to a
particular company, such as real or perceived adverse economic conditions,
changes in the general outlook for corporate earnings, changes in interest or
currency rates or adverse investor sentiment generally. They may also decline
due to factors which affect a particular industry or industries, such as labor
shortages or increased production costs and competitive conditions within an
industry. Equity securities generally have greater price volatility than fixed
income securities.

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

Growth Securities Risk
Each Fund emphasizes investments in equity securities of companies that its
portfolio manager believes will experience relatively rapid earnings growth. The
Funds place particular emphasis on growth securities. Growth securities
typically trade at higher multiples of current earnings than other securities.
Therefore, the values of growth securities may be more sensitive to changes in
current or expected earnings than the values of other securities.

Value Securities Risk
The Funds may invest in companies that may not be expected to experience
significant earnings growth, but whose securities its portfolio manager believes
are selling at a price lower than their true value. The New Asia, Europe Growth
and Emerging Markets Funds place particular emphasis on value securities.
Companies that issue value securities may have experienced adverse business
developments or may be subject to special risks that have caused their
securities to be out of favor. If a portfolio manager's assessment of a
company's prospects is wrong, or if the market does not recognize the value of
the company, the price of its securities may decline or may not approach the
value that the portfolio manager anticipates.

Smaller Company Risk
The general risks associated with equity securities and liquidity risk are
particularly pronounced for securities of companies with smaller market
capitalizations. These companies may have limited product lines, markets or
financial resources or they may depend on a few key employees. Securities of
smaller companies may trade less frequently and in lesser volume than more
widely held securities and their values may fluctuate more sharply than other
securities. They may also trade in the over-the-counter market or on a regional
exchange, or may otherwise have limited liquidity. The Small-Cap Technology Fund
has substantial exposure to this risk because it invests primarily in the
securities of companies with market capitalizations below $200 million. The
Healthcare Innovation, Internet Innovation, Telecom Innovation, Electronics
Innovation, New Asia, Europe Growth, Select World and Emerging Markets Funds
also have significant exposure to this risk because they invest substantial
assets

                                       23
<PAGE>

in companies with medium-sized market capitalizations, which are smaller and
generally less-seasoned than the largest companies.

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

Derivatives Risk
All of the Funds may use derivatives, which are financial contracts whose value
depends on, or is derived from, the value of an underlying asset, reference rate
or index. The various derivative instruments that the Funds may use are
referenced under "Characteristics and Risks of Securities and Investment
Techniques--Derivatives" in this Prospectus and described in more detail under
"Investment Objectives and Policies" in the Statement of Additional
Information. The Funds may sometimes use derivatives as part of a strategy
designed to reduce exposure to other risks, such as interest rate or currency
risk. The Funds may also use derivatives for leverage, which increases
opportunities for gain but also involves greater risk of loss due to leveraging
risk. A Fund's use of derivative instruments involves risks different from, or
possibly greater than, the risks associated with investing directly in
securities and other traditional investments. Derivatives are subject to a
number of risks described elsewhere in this section, such as liquidity risk,
market risk, credit risk and management risk. They also involve the risk of
mispricing or improper valuation and the risk that changes in the value of the
derivative may not correlate perfectly with the underlying asset, rate or index.
In addition, a Fund's use of derivatives may increase or accelerate the amount
of taxes payable by shareholders. A Fund investing in a derivative instrument
could lose more than the principal amount invested. Also, suitable derivative
transactions may not be available in all circumstances and there can be no
assurance that a Fund will engage in these transactions to reduce exposure to
other risks when that would be beneficial.

Foreign (non-U.S.) Investment Risk
A Fund that invests in foreign securities, and particularly the New Asia, Europe
Growth, Select World and Emerging Markets Funds, may experience more rapid and
extreme changes in value than Funds that invest exclusively in securities of
U.S. issuers or securities that trade exclusively in U.S. markets. The
securities markets of many foreign countries are relatively small, with a
limited number of companies representing a small number of industries.
Additionally, issuers of foreign securities are usually not subject to the same
degree of regulation as U.S. issuers. Reporting, accounting and auditing
standards of foreign countries differ, in some cases significantly, from U.S.
standards. Also, nationalization, expropriation or confiscatory taxation,
currency blockage, political changes or diplomatic developments could adversely
affect a Fund's investments in a foreign country. In the event of
nationalization, expropriation or other confiscation, a Fund could lose its
entire investment in foreign securities. To the extent that a Fund, such as New
Asia, Europe Growth, Select World and Emerging Markets Funds, invests a
significant portion of its assets in a narrowly defined geographic area such as
Europe, Asia or South America, the Fund will generally have more exposure to
regional economic risks associated with foreign investments. Adverse conditions
in certain regions (such as Southeast Asia) can also adversely affect securities
of other countries whose economies appear to be unrelated. In addition, special
U.S. tax considerations may apply to a Fund's investment in foreign securities.

Emerging Markets Risk
Foreign investment risk may be particularly high to the extent that a Fund
invests in emerging market securities of issuers based in countries with
developing economies. These securities may present market, credit, currency,
liquidity, legal, political and other risks different from, or greater than, the
risks of investing in developed foreign countries. The Emerging Markets Fund is
particularly susceptible to these risks because it invests principally in
companies located in emerging markets countries. The New Asia and Select World
Funds also have substantial exposure to these risks because these Funds may
invest a significant portion of their assets in emerging market securities. In
addition, the risks associated with investing in a narrowly defined geographic
area (discussed above under "Foreign (non-U.S.) Investment Risk") are more
pronounced for the Funds that invest in emerging markets.

                                       24

Currency Risk
Funds that invest directly in foreign currencies or in securities that trade in,
and receive revenues in, foreign currencies are subject to the risk that those
currencies will decline in value relative to the U.S. Dollar, or, in the case of
hedging positions, that the U.S. Dollar will decline in value relative to the
currency being hedged. The New Asia, Europe Growth, Select World and Emerging
Markets Funds are particularly sensitive to currency risk. Currency rates in
foreign countries may fluctuate significantly over short periods of time for a
number of reasons, including changes in interest rates, intervention (or the
failure to intervene) by U.S. or foreign governments, central banks or
supranational entities such as the International Monetary Fund, or by the
imposition of currency controls or other political developments in the U.S. or
abroad.

Focused Investment Risk
Focusing Fund investments in a small number of issuers, industries or foreign
currencies increases risk. Funds, such as the Select World Fund, that invest in
a relatively small number of issuers may have more risk because changes in the
value of a single security or the impact of a single economic, political or
regulatory occurrence may have a greater adverse impact on the Fund's net asset
value. Some of those issuers also may present substantial credit or other risks.
The New Asia, Europe Growth, Select World and Emerging Markets Funds may be
subject to increased risk to the extent that they focus their investments in
securities denominated in a particular foreign currency or in a narrowly defined
geographic area outside the U.S. The Internet Innovation, Electronics Innovation
and Small-Cap Technology Funds are subject to risks prevalent in the Internet,
electronics and technology sectors respectively, such as the risks of rapid
obsolescence of products and services, significant losses, increased volatility
of these companies' securities and limited operating histories, because they
"concentrate" their investments in these sectors. Similarly, the Telecom
Innovation and Healthcare Innovation Funds "concentrate" their investments in
the telecommunications and health care industries, respectively, and therefore
are subject to the risks particular to those industries, such as the risks
associated with additional government regulation of the telecommunications and
health care industries and changes to existing regulations and government
subsidy levels. Also, the Funds may from time to time have greater risk to the
extent they invest a substantial portion of their assets in related industries
such as "technology" or "financial and business services", which may share
common characteristics and react similarly to market developments.

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

Interest Rate Risk
To the extent that Funds purchase fixed income securities for investment or
defensive purposes, they will be subject to interest rate risk, a market risk
relating to investments in fixed income securities such as bonds and notes. As
interest rates rise, the value of fixed income securities in a Fund's portfolio
are likely to decrease. Securities with longer "durations" (defined below) tend
to be more sensitive to changes in interest rates, usually making them more
volatile than securities with shorter durations. Duration is a measure of the
expected life of a fixed income security that is used to determine the
sensitivity of a security's price to changes in interest rates. A Fund with a
longer average portfolio duration will be more sensitive to changes in interest
rates than a Fund with a shorter average portfolio duration.

Credit Risk
All of the Funds are subject to credit risk. This is the risk that the issuer or
the guarantor of a fixed income security, or the counterparty to a derivatives
contract, repurchase agreement or a loan of portfolio securities, is unable or
unwilling to make timely principal and/or interest payments, or to otherwise
honor its obligations. Securities are subject to varying degrees of credit risk,
which are often reflected in their credit ratings.

                                       25
<PAGE>

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

Management of the Funds

Investment Adviser and Administrator

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

PIMCO Advisors is located at 800 Newport Center Drive, Newport Beach, California
92660. Organized in 1987, PIMCO Advisors provides investment management and
advisory services to private accounts of institutional and individual clients
and to mutual funds. As of March 31, 2000, PIMCO Advisors and its subsidiary
partnerships had more than $264 billion in assets under management.

PIMCO Advisors has retained its subsidiary PIMCO/Allianz International Advisors
LLC to manage the investments of the New Asia, Europe Growth, Select World and
Emerging Markets Funds. The PIMCO Equity Advisors division of PIMCO Advisors
manages the investments of the Healthcare Innovation, Internet Innovation,
Small-Cap Technology, Telecom Innovation and Electronics Innovation Funds (PIMCO
Equity Advisors and PIMCO/Allianz International Advisors LLC are each referred
to as a "Sub-Adviser" in this prospectus). See "Sub-Advisers" below.

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

Advisory Fees

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

The Funds will pay monthly advisory fees to PIMCO Advisors at the following
annual rates (stated as a percentage of the average daily net assets of each
Fund taken separately):

Fund                                                    Advisory Fees

Healthcare Innovation and Telecom Innovation Funds          0.70%

Europe Growth and Select World Funds                        0.75%

Internet Innovation, Small-Cap Technology and               0.80%
Electronics Innovation Funds

New Asia and Emerging Markets Funds                         1.00%



Administrative Fees

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

                                       27

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


Fund                                                        Administrative Fees

Healthcare Innovation, Internet Innovation, Small-Cap              [0.50]%
Technology, Telecom Innovation and Electronics
Innovation Funds

New Asia, Europe Growth, Select World and                          [0.70]%
Emerging Markets Funds


12b-1 Plan for Class D Shares

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

Sub-Advisers

Each Sub-Adviser has full investment discretion and makes all determinations
with respect to the investment of a Fund's assets. The following provides
summary information about each Sub-Adviser, including the Fund(s) it manages.

How Fund Shares Are Priced

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

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

Investments initially valued in currencies other than the U.S. dollar are
converted to U.S. dollars using exchange rates obtained from pricing services.
As a result, the NAV of a Fund's shares may be affected by changes in the value
of currencies in relation to the U.S. dollar. The value of securities traded in
markets outside the United States or denominated in currencies other than the
U.S. dollar may be affected significantly on a day that the New York Stock
Exchange is closed and an investor is not able to purchase, redeem or exchange
shares. In particular, the calculation of the NAV of the New Asia, Europe
Growth, Select World and Emerging Markets Funds may not take place
contemporaneously with the determination of the prices of foreign securities
used in the NAV calculations.

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

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


How to Buy and Sell Shares

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

General Information

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

                                       31
<PAGE>

transaction fees and/or other additional amounts for such services, which may
change over time. These fees and additional amounts could reduce your investment
returns on Class D shares of the Funds.

Your financial service firm may have omnibus accounts and similar arrangements
with the Trust and may be paid for providing sub-transfer agency and other
services. A firm may be paid for its services directly or indirectly by the
Funds, PIMCO Advisors or an affiliate (normally not to exceed an annual rate of
0.35% of a Fund's average daily net assets attributable to its Class D shares
and purchased through such firm for its clients). Your firm may establish
various minimum investment requirements for Class D shares of the Funds and may
also establish certain privileges with respect to purchases, redemptions and
exchanges of Class D shares or the reinvestment of dividends. Please contact
your firm for information.

This Prospectus should be read in connection with your firm's materials
regarding its fees and services.

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

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

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

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

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

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

                                       32

Investment Minimums

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


          Initial Investment                      Subsequent Investments
           $2,500 per Fund                            $100 per Fund



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

Exchanging Shares
Except as provided below or in the applicable Fund's or series' prospectus(es),
you may exchange your Class D shares of any Fund for Class D shares of any other
Fund or series of PIMCO Funds: Pacific Investment Management Series that offers
Class D shares. Shares are exchanged on the basis of their respective NAVs next
calculated after your exchange order is received by the Distributor. Currently,
the Trust does not charge any exchange fees or charges. Your financial service
firm may impose various fees and charges, investment minimums and other
requirements with respect to exchanges. In addition, an exchange is generally a
taxable event which will generate capital gains or losses, and special rules may
apply in computing tax basis when determining gain or loss. Please contact your
financial service firm to exchange your shares and for additional information
about the exchange privilege.

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

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

Your financial service firm is obligated to transmit your redemption orders to
the Distributor promptly and is responsible for ensuring that your redemption
request is in proper form. Your financial service firm will be responsible for
furnishing all necessary documentation to the Distributor or the Trust's
transfer agent and may charge you for its services. Redemption proceeds will be
forwarded to your financial service firm as promptly as possible and in any
event within seven days after the redemption request is received by the
Distributor in good order.

Redemptions of Fund shares may be suspended when trading on the Exchange is
restricted or during an emergency which makes it impracticable for the Funds to
dispose of their securities or to determine fairly the value of their net

                                       33
<PAGE>

assets, or during any other period as permitted by the Securities and Exchange
Commission for the protection of investors. Under these and other unusual
circumstances, the Trust may suspend redemptions or postpone payment for more
than seven days, as permitted by law.

Redemptions In Kind
The Trust had agreed to redeem shares of each Fund solely in cash up to the
lesser of $250,000 or 1% of the Fund's net assets during any 90-day period for
any one shareholder. In consideration of the best interests of the remaining
shareholders, the Trust may pay any redemption proceeds exceeding this amount in
whole or in part by a distribution in kind of securities held by a Fund in lieu
of cash. It is highly unlikely that your shares would ever be redeemed in kind.
If your shares are redeemed in kind, you should expect to incur transaction
costs upon the disposition of the securities received in the distribution.


Fund Distributions

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

</TABLE>


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

You can choose from the following distribution options:

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

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

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

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

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

                                       34

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

Tax Consequences

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

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

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

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

A Note on Foreign Investments. A Fund's investment in foreign securities may be
subject to foreign withholding taxes. In that case, the Fund's yield on those
securities would be decreased. In addition, a Fund's investments in foreign
securities or foreign currencies may increase or accelerate the Fund's
recognition of ordinary income and may affect the timing or amount of the Fund's
distributions.

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

Characteristics and Risks of Securities
and Investment Techniques

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

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

The Healthcare Innovation, Internet Innovation, Small-Cap Technology, Telecom
Innovation, Electronics Innovation, New Asia, Europe Growth, Select World and
Emerging Markets Funds will each invest primarily in common stocks, and may also
invest in other kinds of equity securities, including preferred stocks and
securities (including fixed income securities and warrants) convertible into or
exercisable for common stocks. Each of these Funds may invest a portion of their
assets in fixed income securities. The Funds may temporarily hold up to 100% of
their assets in short-term U.S. Government securities and other money market
instruments for defensive purposes in response to unfavorable market and other
conditions. The New Asia, Europe Growth, Select World and Emerging Markets Funds
may also hold up to 100% of their assets in other domestic fixed income, foreign
fixed income and equity securities principally traded in the U.S., including
obligations issued or guaranteed by a foreign government or its agencies,
authorities or instrumentalities, corporate bonds and American Depository
Receipts, for temporary defensive purposes.

The temporary defensive strategies described in this section would be
inconsistent with the investment objective and principal investment strategies
of each of the noted Funds and may adversely affect the Fund's ability to
achieve its investment objective.

Companies With Smaller Market Capitalizations
Each of the Funds may invest in securities of companies with market
capitalizations that are small compared to other publicly traded companies. The
Small-Cap Technology Fund invests primarily in smaller companies and is
especially sensitive to the risks described below. In addition, the Healthcare
Innovation, Internet Innovation, Telecom Innovation, Electronics Innovation, New
Asia, Europe Growth, Select World and Emerging Markets Funds generally have
significant exposure to these risks.

Companies which are smaller and less well-known or seasoned than larger, more
widely held companies may offer greater opportunities for capital appreciation,
but may also involve risks different from, or greater than, risks normally
associated with larger companies. Larger companies generally have greater
financial resources, more extensive research and development, manufacturing,
marketing and service capabilities, and more stability and greater depth of
management and technical personnel than smaller companies. Smaller companies may
have limited product lines, markets or financial resources or may depend on a
small, inexperienced management group. Securities of smaller companies may trade
less frequently and in lesser volume than more widely held securities and their
values may fluctuate more abruptly or erratically than securities of larger
companies. They may also trade in the over-the-counter market or on a regional
exchange, or may otherwise have limited liquidity. These securities

                                       36
<PAGE>

may therefore be more vulnerable to adverse market developments than securities
of larger companies. Also, there may be less publicly available information
about smaller companies or less market interest in their securities as compared
to larger companies, and it may take longer for the prices of the securities to
reflect the full value of a company's earnings potential or assets.

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

The Funds may purchase securities in initial public offerings (IPOs). These
securities are subject to many of the same risks of investing in companies with
smaller market capitalizations. Securities issued in IPOs have no trading
history, and information about the companies may be available for very limited
periods. In addition, the prices of securities sold in IPOs may be highly
volatile. A Fund may not be able to invest in securities issued in IPOs to the
extent desired because, for example, only a small portion of the securities
being offered in an IPO may be made available to the Fund or because under
certain market conditions few companies may issue securities in IPOs.

Foreign Securities
The New Asia, Europe Growth, Select World and Emerging Markets Funds normally
invest principally in securities of foreign issuers, securities traded
principally in securities markets outside the United States and/or securities
denominated in foreign currencies (together, "foreign securities").  The
Healthcare Innovation, Internet Innovation, Small-Cap Technology, Telecom
Innovation and Electronics Innovation Funds may invest up to 15% of their
respective assets in foreign securities.

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

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

Emerging Market Securities
The Funds may invest in securities of issuers based in or that trade principally
in countries with developing (or "emerging market") economies.  The Emerging
Markets Fund is particularly susceptible to these risks because it invests
principally in companies located in emerging markets countries.  The New Asia
and Select World Funds also

                                       37
<PAGE>

have substantial exposure to these risks because these Funds may invest
significant portions of their assets in emerging market securities. Investing in
emerging market securities imposes risks different from, or greater than, risks
of investing in domestic securities or in foreign, developed countries. These
risks include: smaller market capitalization of securities markets, which may
suffer periods of relative illiquidity; significant price volatility;
restrictions on foreign investment; and possible repatriation of investment
income and capital. In addition, foreign investors may be required to register
the proceeds of sales, and future economic or political crises could lead to
price controls, forced mergers, expropriation or confiscatory taxation, seizure,
nationalization or the creation of government monopolies. The currencies of
emerging market countries may experience significant declines against the U.S.
dollar, and devaluation may occur subsequent to investments in these currencies
by a Fund. Inflation and rapid fluctuations in inflation rates have had, and may
continue to have, negative effects on the economies and securities markets of
certain emerging market countries.

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

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

Foreign Currencies
A Fund that invests directly in foreign currencies or in securities that trade
in, and receive revenues in, foreign currencies will be subject to currency
risk. The New Asia, Europe Growth, Select World and Emerging Markets Funds are
particularly sensitive to this risk.

Foreign currency exchange rates may fluctuate significantly over short periods
of time. They generally are determined by supply and demand and the relative
merits of investments in different countries, actual or perceived changes in
interest rates and other complex factors. Currency exchange rates also can be
affected unpredictably by intervention (or the failure to intervene) by U.S. or
foreign governments or central banks, or by currency controls or political
developments. For example, significant uncertainty surrounds the recent
introduction of the euro (a common currency unit for the European Union) in
January 1999 and the effect it may have on the value of securities denominated
in local European currencies.  The Europe Growth Fund is especially susceptible
to risks associated with the introduction of the euro because it invests
principally in European companies, many of which are located in European
Monetary Union countries.  The euro and other currencies in which the Funds'
assets are denominated may be devalued against the U.S. dollar, resulting in a
loss to the Funds.

Foreign Currency Transactions.  The Funds may enter into forward foreign
currency exchange contracts to reduce the risks of adverse changes in foreign
exchange rates. In addition, the Funds may buy and sell foreign currency futures
contracts and options on foreign currencies and foreign currency futures. A
forward foreign currency exchange contract, which involves an obligation to
purchase or sell a specific currency at a future date at a price set at the time
of the contract, reduces a Fund's exposure to changes in the value of the
currency it will deliver and

                                       38
<PAGE>

increases its exposure to changes in the value of the currency it will receive
for the duration of the contract. The effect on the value of a Fund is similar
to selling securities denominated in one currency and purchasing securities
denominated in another currency. Contracts to sell foreign currency would limit
any potential gain which might be realized by a Fund if the value of the hedged
currency increases. A Fund may enter into these contracts to hedge against
foreign exchange risk arising from the Fund's investment or anticipated
investment in securities denominated in foreign currencies. Suitable hedging
transactions may not be available in all circumstances and there can be no
assurance that a Fund will engage in such transactions at any given time or from
time to time. Also, such transactions may not be successful and may eliminate
any chance for a Fund to benefit from favorable fluctuations in relevant foreign
currencies.

The New Asia, Europe Growth, Select World and Emerging Markets Funds may also
enter into these contracts for purposes of increasing exposure to a foreign
currency or to shift exposure to foreign currency fluctuations from one currency
to another. To the extent that it does so, a Fund will be subject to the
additional risk that the relative value of currencies will be different than
anticipated by the Fund's portfolio manager. The Funds may use one currency (or
a basket of currencies) to hedge against adverse changes in the value of another
currency (or a basket of currencies) when exchange rates between the two
currencies are positively correlated. Each Fund will segregate assets determined
to be liquid by PIMCO Advisors or a Sub-Adviser in accordance with procedures
established by the Board of Trustees to cover its obligations under forward
foreign currency exchange contracts entered into for non-hedging purposes.

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

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

Derivatives
Each Fund may, but is not required to, use a number of derivative instruments
for risk management purposes or as part of its investment strategies. Generally,
derivatives are financial contracts whose value depends upon, or is derived
from, the value of an underlying asset, reference rate or index, and may relate
to stocks, bonds, interest rates, currencies or currency exchange rates,
commodities, and related indexes. A portfolio manager may decide not to employ
any of these strategies and there is no assurance that any derivatives strategy
used by a Fund will succeed.

Examples of derivative instruments include options contracts, futures contracts,
options on futures contracts and swap agreements. The Funds may purchase and
sell (write) call and put options on securities, securities indexes and foreign
currencies. Each Fund may purchase and sell futures contracts and options
thereon with respect to securities, securities indexes and foreign currencies.
A description of these and other derivative instruments that the Funds may use
are described under "Investment Objectives and Policies" in the Statement of
Additional Information.

A Fund's use of derivative instruments involves risks different from, or greater
than, the risks associated with investing directly in securities and other more
traditional investments. A description of various risks associated with

                                       39
<PAGE>

particular derivative instruments is included in "Investment Objectives and
Policies" in the Statement of Additional Information. The following provides a
more general discussion of important risk factors relating to all derivative
instruments that may be used by the Funds.

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

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

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

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

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

Market and Other Risks  Like most other investments, derivative instruments are
subject to the risk that the market value of the instrument will change in a way
detrimental to a Fund's interest. If a portfolio manager incorrectly forecasts
the values of securities, currencies or interest rates or other economic factors
in using derivatives for a Fund, the Fund might have been in a better position
if it had not entered into the transaction at all. While some strategies
involving derivative instruments can reduce the risk of loss, they can also
reduce the opportunity for gain or even result in losses by offsetting favorable
price movements in other Fund investments. A Fund may also have to buy or sell a
security at a disadvantageous time or price because the Fund is legally required
to maintain offsetting positions or asset coverage in connection with certain
derivatives transactions.

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

Equity-Linked Securities
The Funds may invest in equity-linked securities. Equity-linked securities are
privately issued securities whose investment results are designed to correspond
generally to the performance of a specified stock index or "basket" of

                                       40
<PAGE>

stocks, or sometimes a single stock. To the extent that a Fund invests in
equity-linked securities whose return corresponds to the performance of a
foreign securities index or one or more of foreign stocks, investing in
equity-linked securities will involve risks similar to the risks of investing in
foreign equity securities. See "Foreign Securities" above. In addition, an
investing Fund bears the risk that the issuer of an equity-linked security may
default on its obligations under the security. Equity-linked securities may be
considered illiquid and thus subject to the Funds' restrictions on investments
in illiquid securities.

Credit Ratings and Unrated Securities
The Funds may invest in securities based on their credit ratings assigned by
rating agencies such as Moody's Investors Service, Inc. ("Moody's") and
Standard & Poor's Ratings Services ("S&P"). Moody's, S&P and other rating
agencies are private services that provide ratings of the credit quality of
fixed income securities, including convertible securities. The Appendix to the
Statement of Additional Information describes the various ratings assigned to
fixed income securities by Moody's and S&P. Ratings assigned by a rating agency
are not absolute standards of credit quality and do not evaluate market risk.
Rating agencies may fail to make timely changes in credit ratings and an
issuer's current financial condition may be better or worse than a rating
indicates. A Fund will not necessarily sell a security when its rating is
reduced below its rating at the time of purchase. PIMCO Advisors and the Sub-
Advisers do not rely solely on credit ratings, and develop their own analysis of
issuer credit quality.

A Fund may purchase unrated securities (which are not rated by a rating agency)
if its portfolio manager determines that the security is of comparable quality
to a rated security that the Fund may purchase. Unrated securities may be less
liquid than comparable rated securities and involve the risk that the portfolio
manager may not accurately evaluate the security's comparative credit rating.

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

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

Short Sales
Each Fund may make short sales as part of its overall portfolio management
strategies or to offset a potential decline in the value of a security. A short
sale involves the sale of a security that is borrowed from a broker or other
institution to complete the sale. A Fund may only enter into short selling
transactions if the security sold short is held in the Fund's portfolio or if
the Fund has the right to acquire the security without the payment of further
consideration. For these purposes, a Fund may also hold or have the right to
acquire securities which, without the payment of any further consideration, are
convertible into or exchangeable for the securities sold short. Short sales
expose a Fund to the risk that it will be required to acquire, convert or
exchange securities to replace the borrowed securities (also known as
"covering" the short position) at a time when the securities sold short have
appreciated in value, thus resulting in a loss to the Fund.

                                       41
<PAGE>

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

Repurchase Agreements
Each Fund may enter into repurchase agreements, in which the Fund purchases a
security from a bank or broker-dealer that agrees to repurchase the security at
the Fund's cost plus interest within a specified time. If the party agreeing to
repurchase should default, the Fund will seek to sell the securities which it
holds. This could involve procedural costs or delays in addition to a loss on
the securities if their value should fall below their repurchase price. Those
Funds whose investment objectives do not include the earning of income will
invest in repurchase agreements only as a cash management technique with respect
to that portion of its portfolio maintained in cash. Repurchase agreements
maturing in more than seven days are considered illiquid securities.

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

Illiquid Securities
Each Fund may invest in securities that are illiquid so long as not more than
15% of the value of the Fund's net assets (taken at market value at the time of
investment) would be invested in such securities. Certain illiquid securities
may require pricing at fair value as determined in good faith under the
supervision of the Board of Trustees. A portfolio manager may be subject to
significant delays in disposing of illiquid securities held by the Fund, and
transactions in illiquid securities may entail registration expenses and other
transaction costs that are higher than those for transactions in liquid
securities. The term "illiquid securities" for this purpose means securities
that cannot be disposed of within seven days in the ordinary course of business
at approximately the amount at which a Fund has valued the securities. Please
see "Investment Objectives and Policies" in the Statement of Additional
Information for a listing of various securities that are generally considered to
be illiquid for these purposes. Restricted securities, i.e., securities subject
to legal or contractual restrictions on resale, may be illiquid. However, some
restricted securities (such as securities issued pursuant to Rule 144A under the
Securities Act of 1933 and certain commercial paper) may be treated as liquid,
although they may be less liquid than registered securities traded on
established secondary markets.

Investment in Other Investment Companies
The New Asia, Europe Growth, Select World and Emerging Markets Funds may invest
up to [10%] of their assets in securities of other investment companies, such as
closed-end management investment companies, or in pooled accounts or other
investment vehicles which invest in foreign markets.  The Healthcare Innovation,
Internet Innovation, Small-Cap Technology, Telecom Innovation and Electronics
Innovation Funds may invest up to 5% of their assets in such securities.  As a
shareholder of an investment company, a Fund may indirectly bear service and
other fees which are in addition to the fees the Fund pays its service
providers.

Portfolio Turnover
The length of time a Fund has held a particular security is not generally a
consideration in investment decisions. A change in the securities held by a Fund
is known as "portfolio turnover." Each Fund may engage in active and

                                       42
<PAGE>

frequent trading of portfolio securities to achieve its investment objective and
principal investment strategies, particularly during periods of volatile market
movements. High portfolio turnover (e.g., over 100%) involves correspondingly
greater expenses to a Fund, including brokerage commissions or dealer mark-ups
and other transaction costs on the sale of securities and reinvestments in other
securities. Such sales may also result in realization of taxable capital gains,
including short-term capital gains (which are taxed at ordinary income tax rates
when distributed to shareholders who are individuals). The trading costs and tax
effects associated with portfolio turnover may adversely affect a Fund's
performance.

Changes in Investment Objectives and Policies
The investment objective of each Fund described in this Prospectus may be
changed by the Board of Trustees without shareholder approval. Unless otherwise
stated in the Statement of Additional Information, all investment policies of
the Funds may be changed by the Board of Trustees without shareholder approval.
If there is a change in a Fund's investment objective or policies, including a
change approved by shareholder vote, shareholders should consider whether the
Fund remains an appropriate investment in light of their then current financial
position and needs.

New Funds
In addition to the risks described under "Summary of Principal Risks" above
and in this section, the Funds are newly formed and therefore have no history
upon which investors can evaluate their likely performance. Accordingly, there
can be no assurance that the Funds will achieve their investment objective.
Also, it is possible that the Funds may invest in securities offered in initial
public offerings and other similar transactions which, because of each Fund's
size, may have a disproportionate impact on each Fund's performance results. The
Funds would not necessarily have achieved the same performance results if their
aggregate net assets had been greater.

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

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

shareholder approval by vote of a majority of the outstanding voting securities
of that Fund.  Under these restrictions:

     a.   each Fund may borrow money to the maximum extent permitted by law,
          ----
including without limitation (i) borrowing from banks or entering into reverse
repurchase agreements, or employing similar investment techniques, and pledging
its assets in connection therewith, if immediately after each borrowing and
continuing thereafter, there is asset coverage of 300%, and (ii) entering into

pledges or other encumbrances.) (For the purpose of this restriction, collateral
arrangements with respect to the writing of options, futures contracts, options
on futures contracts, and collateral arrangements with respect to initial and
variation margin are not deemed to be a pledge of assets and neither such
arrangements nor the purchase or sale of futures or related options are deemed
to be the issuance of a senior security.);

Item 24.  Persons Controlled by or Under Common Control with Registrant.

          Not applicable.

Item 25.  Indemnification

     Reference is made to Article VIII, Section 1, of the Registrant's Second
Amended and Restated Agreement and Declaration of Trust, which is incorporated
by reference herein.

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

Item 27.  Business and Other Connections of Investment Advisor and Portfolio
     Managers.

     Unless otherwise stated, the principal business address of each
organization listed in 800 Newport Center Drive, Newport Beach, CA  92660.
