                                  PROSPECTUS
                                October 1, 1995
 
  PIMCO Funds (the "Trust") is a no-load, open-end, management investment
company ("mutual fund") consisting of eighteen separate investment portfolios
(the "Funds"). Each Fund has its own investment objective and policies. The
Trust is designed to provide access to the professional investment management
services offered by Pacific Investment Management Company ("PIMCO"), which
serves as investment adviser to the Funds.
 
  The PIMCO Funds described in this Prospectus are as follows:
 
                FIXED INCOME FUNDS           EQUITY FUNDS
                Money Market Fund*           StocksPLUS Fund

                Foreign Fund
                Global Fund
                International Fund
 
  Information about the investment objective of each Fund, along with a
detailed description of the types of securities in which each Fund may invest,
and of investment policies and restrictions applicable to each Fund, are set
forth in this Prospectus. There can be no assurance that the investment
objective of any Fund will be achieved. Because the market value of the Funds'
investments will change, the investment returns and net asset value per share
of each Fund also will vary.
 
  Each Fund offers two classes of shares: the "Institutional Class" and the
"Administrative Class." Shares of the Institutional Class are offered
primarily for direct investment by investors such as pension and profit
sharing plans, employee benefit trusts, endowments, foundations, corporations,
other institutions, and high net worth individuals. They also are offered
through certain financial intermediaries that charge their customers
transaction or other fees with respect to the customers' investment in the
Funds. Shares of the Administrative Class are offered primarily through
brokers, retirement plan administrators and other financial intermediaries.
Administrative Class shares pay service fees to such entities for services
they provide to shareholders of that class. Shares of each class of the Funds
are offered for sale at the relevant next determined net asset value for that
class with no sales charge. Shares of the PIMCO International Fund are offered
only to private account clients of PIMCO.
 
  THE PIMCO HIGH YIELD FUND INVESTS PRIMARILY, AND THE PIMCO COMMERCIAL
MORTGAGE SECURITIES FUND INVESTS UP TO 35% OF ITS ASSETS, IN JUNK BONDS, WHICH
ARE SUBJECT TO HIGH RISK, AND SPECULATIVE WITH REGARD TO PAYMENT OF INTEREST
AND RETURN OF PRINCIPAL. INVESTORS SHOULD CAREFULLY CONSIDER THESE RISKS
BEFORE INVESTING IN THESE FUNDS.
 
  Each of the Funds, except the PIMCO Money Market Fund, may invest all of its
assets in derivative instruments, some of which may be particularly sensitive
to changes in prevailing interest rates. Unexpected changes in interest rates
may adversely affect the value of a Fund's investments in particular
derivative instruments.
 
  This Prospectus sets forth concisely the information a prospective investor
should know before investing in the Funds. It should be read and retained for
ready reference to information about the Funds. A Statement of Additional
Information, dated October 1, 1995, as supplemented from time to time,
containing additional and more detailed information about the Funds, has been
filed with the Securities and Exchange Commission and is hereby incorporated
by reference into this Prospectus. It is available without charge and may be
obtained by writing or calling:

company ("mutual fund"), organized as a Massachusetts business trust on
February 19, 1987. The Trust consists of eighteen separate investment
portfolios (the "Funds"). The investment objective of each of the PIMCO Money
Market Fund and PIMCO Short-Term Fund is to seek to obtain maximum current

prudent investment management. The investment objective of the PIMCO Growth
Stock Fund is to seek long-term growth of capital. The investment objective of
both the PIMCO StocksPLUS Fund and the PIMCO VersaSTYLE Equity Fund is to seek

                      INVESTMENT RISKS AND CONSIDERATIONS
 
  The following are some of the primary risks relevant to an investment in the
Funds and to the securities in which the Funds invest. Investors should read
the Prospectus carefully for a more complete discussion of the risks relating
to an investment in the Funds. The value of all securities and other
instruments held by the Funds will vary from time to time in response to a wide
variety of market factors. Consequently, the net asset value per share of each
Fund will vary, except that the PIMCO Money Market Fund shall attempt to
maintain a net asset value of $1.00 per share, although there can be no
assurance that the Fund will be successful in doing so. The net asset value per
share of any Fund may be less at the time of redemption than it was at the time
of investment. The value of fixed income securities can be expected to vary
inversely with changes in prevailing interest rates, i.e., as interest rates
rise, market value tends to decrease, and vice versa. In addition, certain of
the Funds may invest in securities rated lower than Baa by Moody's Investors
Service, Inc. ("Moody's") or BBB by Standard & Poor's Corporation ("S&P"). Such
securities carry a high degree of credit risk and are considered speculative by
the major rating agencies. Certain Funds may invest in securities of foreign
issuers, which may be subject to additional risk factors, including foreign
currency and political risks, not applicable to securities of U.S. issuers.
Certain of the Funds' investment techniques may involve a form of borrowing,
which may tend to exaggerate the effect on net asset value of any increase or
decrease in the market value of a Fund's portfolio and may require liquidation
of portfolio positions when it is not advantageous to do so. Certain Funds may
sell securities short, which exposes the Fund to a risk of loss if the value of
the security sold short should increase.
 
  All Funds, except the PIMCO Money Market Fund, may use derivative
instruments, consisting of futures, options, options on futures and swap
agreements for hedging purposes or as part of their investment strategies. Use
of these instruments may involve certain costs and risks, including the risk
that a Fund could not close out a position when it would be most advantageous
to do so, the risk of an imperfect correlation between the value of the
securities being hedged and the value of the particular derivative instrument,
and the risk that unexpected changes in interest rates may adversely affect the
value of a Fund's investments in particular derivative instruments.
 
  The PIMCO Commercial Mortgage Securities, Foreign, Global and International
Funds are "non-diversified" for purposes of the Investment Company Act of 1940,
meaning that they may invest a greater percentage of their assets in the
securities of one issuer than the other Funds. As "non-diversified" portfolios,
these Funds may be more susceptible to risks associated with a single economic,
political or regulatory occurrence than a diversified portfolio might be. See
"Investment Objectives and Policies" and "Characteristics and Risks of
Securities and Investment Techniques" for additional information.
 
                   INVESTMENT ADVISER AND FUND ADMINISTRATOR
 
  Pacific Investment Management Company ("PIMCO") serves as investment adviser
("Adviser") to the Trust, and also serves as the Trust's administrator. The
Adviser is an investment management firm established in 1971 that currently has
over $66 billion of assets under management. The Adviser is a subsidiary of
PIMCO Advisors L.P. ("PIMCO Advisors"), which has over $84 billion of assets
under management. See "Management of the Trust."
 
                               PURCHASE OF SHARES
 
  Each Fund offers two classes of shares: the "Institutional Class" and the
"Administrative Class." Shares of the Institutional Class are offered primarily
for direct investment by institutional investors and high net worth
individuals. They also are offered through certain financial intermediaries
that charge their customers transaction or other fees with respect to the
customers' investment in the Funds. Shares of the Administrative Class are
offered primarily through brokers, retirement plan administrators and other
financial intermediaries. Administrative Class shares pay service fees to such
entities for services they provide to shareholders of that class.
 
  Shares of each class of the Funds are offered at the relevant next determined
net asset value with no sales charge. The minimum initial investment for shares
of either class is $1,000,000. Shares of the PIMCO International Fund are
offered only to private account clients of PIMCO. See "Purchase of Shares."
 
<PAGE>
 
                                                                               5
 
                           REDEMPTIONS AND EXCHANGES
 
  Shares of each class of each Fund may be redeemed without cost at the
relevant net asset value per share of the class of that Fund next determined
after receipt of the redemption request. The redemption price may be more or
less than the purchase price.
 
  Shares of a class of any Fund may be exchanged for shares of the same class
of any other Fund of the Trust offered generally to the public on the basis of
relative net asset values, except that only private account clients of PIMCO
may purchase shares of the PIMCO International Fund. Effective November 1, 1995
shares of a Fund may also be exchanged for shares of the same class of a Series
of the PIMCO Funds: Equity Advisors Series, an affiliated, open-end, management
investment company, comprised primarily of equity portfolios managed by the
subsidiary partnerships of PIMCO Advisors. See "Redemption of Shares."
 
                          DIVIDENDS AND DISTRIBUTIONS
 
  Each Fund will distribute dividends from net investment income at least
monthly (quarterly in the case of the PIMCO International Fund and Equity
Funds), and any net realized capital gains at least annually. All dividends and
distributions will be reinvested automatically at net asset value in additional
shares of the same class of the same Fund, unless cash payment is requested.
Dividends from net investment income with respect to Administrative Class
shares will be lower than those paid with respect to Institutional Class

  The Funds formerly operated under an expense limitation arrangement under
which PIMCO agreed to reimburse or waive certain fees and expenses, subject to
later recoupment, to limit the effective operating expense ratio of each Fund.
The expense limitation provision has been replaced by the new service
arrangements under which PIMCO provides services necessary for the operation of
the Funds for a single administrative fee as shown. See "Fund Administrator"
and "Advisory and Administrative Fees."

                      INVESTMENT OBJECTIVES AND POLICIES
 
  The investment objective and general investment policies of each Fund are
described below. There can be no assurance that the investment objective of
any Fund will be achieved. Because the market value of each Fund's investments
will change, the net asset value per share of each Fund, except the PIMCO
Money Market Fund, also will vary. Specific portfolio securities eligible for
purchase by the Funds, investment techniques that may be used by the Funds,
and the risks associated with these securities and techniques are described
more fully under "Characteristics and Risks of Securities and Investment
Techniques" in the Prospectus and "Investment Objectives and Policies" in the
Statement of Additional Information.
 
FIXED INCOME FUNDS
 
  Each of the Fixed Income Funds differs from the others primarily in the
length of the Fund's duration or the proportion of its investments in certain
types of fixed income securities. For a discussion of the concept of duration,
see "Duration" below.
 
  The investment objective of the PIMCO Money Market Fund and PIMCO Short-Term
Fund is to seek to obtain maximum current income consistent with preservation
of capital and daily liquidity. The PIMCO Money Market Fund also attempts to
maintain a stable net asset value of $1.00 per share, although there can be no
assurance that it will be successful in doing so. Each of the remaining Fixed
Income Funds seeks to maximize total return, consistent with preservation of
capital and prudent investment management.
 
  In selecting securities for each Fixed Income Fund, the Adviser utilizes
economic forecasting, interest rate anticipation, credit and call risk
analysis, foreign currency exchange rate forecasting, and other security
selection techniques. The proportion of each Fund's assets committed to
investment in securities with particular characteristics (such as maturity,
type and coupon rate) will vary based on the Adviser's outlook for the U.S.
and foreign economies, the financial markets, and other factors.
 
  Each of the Fixed Income Funds will invest at least 65% of its assets in the
following types of securities, which, unless specifically provided otherwise
in the description of the Funds that follows, may be issued by domestic or
foreign entities and denominated in U.S. dollars or foreign currencies:
securities issued or guaranteed by the U.S. Government, its agencies or
instrumentalities ("U.S. Government securities"); corporate debt securities,
including convertible securities and corporate commercial paper; mortgage-
backed and other asset-backed securities; structured notes and loan
participations; bank certificates of deposit, fixed time deposits and bankers'
acceptances; repurchase agreements and reverse repurchase agreements;
obligations of foreign governments or their subdivisions, agencies and
instrumentalities; and obligations of international agencies or supranational
entities. Fixed income securities may have fixed, variable, or floating rates
of interest, including rates of interest that vary inversely at a multiple of
a designated or floating rate, or that vary according to changes in relative
values of currencies. Each of the Fixed Income Funds may hold different
percentages of its assets in these various types of securities, and each Fund,
except the PIMCO Money Market Fund, may invest all of its assets in derivative
instruments or in mortgage- or asset-backed securities.
 
  The compositions of the Fixed Income Funds differ as follows:
 
  PIMCO Money Market Fund seeks maximum current income consistent with the
preservation of capital and daily liquidity. It attempts to achieve this
objective by investing at least 95% of its total assets, measured at the time
of investment, in a diversified portfolio of highest quality money market
securities. The Fund may also invest up to 5% of its total assets, measured at
the time of investment, in money market securities that are in the second-
highest rating category for short-term obligations. The Fund's investments in
securities will be limited to U.S. dollar-denominated securities that mature
in 13 months or less from the date of purchase. The Fund may invest in the
following: obligations of the U.S. Government (including its agencies and
instrumentalities); short-term corporate debt securities from domestic and
foreign corporations; obligations of domestic and foreign commercial banks,
savings banks, and savings and loan associations; and commercial paper. The
Fund may invest more than 25% of its total assets in securities or obligations
issued by U.S. banks. The dollar-weighted average portfolio maturity of the
Fund will not exceed 90 days.

                                                                              13
 
  The PIMCO Money Market Fund may invest only in U.S. dollar-denominated money
market instruments that present minimal credit risk and, with respect to at
least 95% of its total assets, measured at the time of investment, that are of
the highest quality. The Adviser will make a determination as to whether a
security presents minimal credit risk under procedures adopted by the Board of
Trustees. A money market instrument will be considered to be highest quality
(1) if rated in the highest rating category (i) by any two nationally
recognized statistical rating organizations ("NRSROs") (e.g., Aaa or Prime-1
by Moody's, AAA or A-1 by S&P, or, (ii) if rated by only one NRSRO, by that
NRSRO, and whose acquisition is approved or ratified by the Board of Trustees;
(2) if unrated but issued by an issuer that has short-term debt obligations of
comparable maturity, priority, and security, and that are rated in the highest
rating category by (i) any two NRSROs or, (ii) if rated by only one NRSRO, by
that NRSRO, and whose acquisition is approved or ratified by the Board of
Trustees; or (3) an unrated security that is of comparable quality to a
security rated in the highest rating category as determined by the Adviser and
whose acquisition is approved or ratified by the Board of Trustees. With
respect to no more than 5% of its total assets, measured at the time of
investment, the Fund may also invest in money market instruments that are in
the second-highest rating category for short-term debt obligations (e.g.,
rated Aa or Prime-2 by Moody's or AA or A-2 by S&P). A money market instrument
will be considered to be in the second-highest rating category under the
criteria described above with respect to instruments considered highest
quality, as applied to instruments in the second-highest rating category.
 
  The PIMCO Money Market Fund may not invest more than 5% of its total assets,
measured at the time of investment, in securities of any one issuer that are
of the highest quality, except that (1) the Fund may invest more than 5% of
its total assets in the securities of a single issuer if rated in the highest
rating category for a period of up to three business days after purchase,
provided that the Fund may not make more than one investment at a time in
accordance with this exception, and (2) this limitation shall not apply to
U.S. Government securities and repurchase agreements with respect thereto. The
Fund may not invest more than the greater of 1% of its total assets or
$1,000,000, measured at the time of investment, in securities of any one
issuer that are in the second-highest rating category, except that this
limitation shall not apply to U.S. Government securities. In the event that an
instrument acquired by the Fund is downgraded or otherwise ceases to be of the
quality that is required for securities purchased by the Fund, the Adviser,
under procedures approved by the Board of Trustees (or the Board of Trustees
itself if the Adviser becomes aware an unrated security is downgraded below
high quality and the Adviser does not dispose of the security or such security
does not mature within five business days) shall promptly reassess whether
such security presents minimal credit risk and determine whether to retain the
instrument.
 
  PIMCO Short-Term Fund invests in a diversified portfolio of fixed income
securities of varying maturities with a maximum portfolio duration of one
year. The Fund may invest up to 10% of its assets in fixed income securities
that are rated below investment grade (rated below Baa by Moody's or BBB by
S&P) but rated B or higher by Moody's or S&P (or, if unrated, determined by
the Adviser to be of comparable quality). Securities rated below investment
grade may be referred to colloquially as "junk bonds." For information on the
risks associated with investments in securities rated below investment grade,
see "Credit and Quality Standards." The Fund may invest up to 20% of its
assets in securities denominated in foreign currencies, and may invest beyond
this limit in U.S. dollar-denominated securities of foreign issuers. Under a
revised investment policy adopted by the Fund, effective December 31, 1995,
the Fund will limit its investments in foreign currency-denominated securities
to 5% of its assets.
 
  PIMCO Low Duration Fund invests in a diversified portfolio of fixed income
securities of varying maturities with a portfolio duration of from one to
three years. The Fund may invest up to 10% of its assets in fixed income
securities that are rated below investment grade but rated B or higher by
Moody's or S&P (or, if unrated, determined by the Adviser to be of comparable
quality). For information on the risks associated with investments in
securities rated below investment grade, see "Credit and Quality Standards."
The Fund may invest up to 20% of its assets in securities denominated in
foreign currencies, and may invest beyond this limit in U.S. dollar-
denominated securities of foreign issuers. The total rate of return for this
Fund is expected to exhibit less volatility than that of the PIMCO Moderate
Duration Fund or the PIMCO Total Return Fund because its duration will be
shorter.
 
  PIMCO Low Duration Fund II has the same policies as the PIMCO Low Duration
Fund, except that its investments in fixed income securities are limited to
those of domestic (U.S.) issuers that are rated at least A by Moody's or S&P
(or, if unrated, determined by the Adviser to be of comparable quality).
 
                                                                    PIMCO FUNDS

  PIMCO Low Duration Fund III has the same policies as the PIMCO Low Duration
Fund, except that it limits its investments with respect to certain socially
sensitive issues. As a matter of non-fundamental policy, the Fund will not
invest in the securities of any issuer determined by the Adviser to be engaged
principally in the provision of healthcare services, the manufacture of
alcoholic beverages, tobacco products, pharmaceuticals or military equipment,
or the operation of gambling casinos. The Fund will also avoid, to the extent
possible on the basis of information available to the Adviser, the purchase of
securities of issuers engaged in the production or trade of pornographic
materials. An issuer will be deemed to be principally engaged in an activity
if it derives more than 10% of its gross revenues from such activities.
 
  PIMCO Moderate Duration Fund invests in a diversified portfolio of fixed
income securities of varying maturities with a portfolio duration range of two
to four years. The Fund may invest up to 10% of its assets in fixed income
securities that are rated below investment grade but rated B or higher by
Moody's or S&P (or, if unrated, determined by the Adviser to be of comparable
quality). For information on the risks associated with investments in
securities rated below investment grade, see "Credit and Quality Standards."
The Fund may invest up to 20% of its assets in securities denominated in
foreign currencies, and may invest beyond this limit in U.S. dollar-
denominated securities of foreign issuers. The total rate of return for this
Fund is expected to exhibit less volatility than that of the PIMCO Total
Return Fund because its duration will normally be shorter. However, the total
rate of return for this Fund is expected to exhibit more volatility than that
of the PIMCO Low Duration Fund because its duration will normally be longer.
 
  PIMCO High Yield Fund invests under normal circumstances at least 65% of its
assets in a diversified portfolio of fixed income securities rated lower than
Baa by Moody's or lower than BBB by S&P but rated at least B by Moody's or S&P
(or, in either case, if unrated, deemed by the Adviser to be of comparable
quality). Such securities are colloquially referred to as "junk bonds." The
remainder of the Fund's assets may be invested in investment grade fixed
income securities (i.e., securities rated at least Baa by Moody's or BBB by
S&P, or, if unrated, deemed by the Adviser to be of comparable quality). The
portfolio duration of the PIMCO High Yield Fund will vary within a range of
from two to six years, depending on the Adviser's view of the potential for
total return offered by a particular duration strategy. The Fund may invest in
securities of foreign issuers, but only those that are U.S. dollar-
denominated. The Fund may also engage in hedging strategies involving equity
options.
 
  Investments in high yield securities, while generally providing greater
potential opportunity for capital appreciation and higher yields than
investments in higher rated securities, also entail greater risk, including
the possibility of default or bankruptcy of the issuer of such securities.
Risk of default or bankruptcy may be greater in periods of economic
uncertainty or recession, as the issuers of high yield securities may be less
able to withstand general economic downturns. The Adviser seeks to reduce risk
through diversification, credit analysis and attention to current developments
and trends in both the economy and financial markets. The value of all fixed
income securities, including those held by the Fund, can be expected to change
inversely with interest rates. For a further discussion of the special risks
of investing in lower rated securities, see "Characteristics and Risks of
Securities and Investment Techniques--High Yield Securities."
 
  PIMCO Total Return Fund invests under normal circumstances at least 65% of
its assets in a diversified portfolio of fixed income securities of varying
maturities with a portfolio duration range of three to six years. The duration
of this Fund will vary within the three- to six-year timeframe based on the
Adviser's forecast for interest rates, but under current conditions is
expected to stay within one year of what the Adviser believes to be the
average duration of the bond market as a whole. The Fund may invest up to 10%
of its assets in fixed income securities that are rated below investment grade
but rated B or higher by Moody's or S&P (or, if unrated, determined by the
Adviser to be of comparable quality). For information on the risks associated
with investments in securities rated below investment grade, see "Credit and
Quality Standards." The Fund may also invest up to 20% of its assets in
securities denominated in foreign currencies, and may invest beyond this limit
in U.S. dollar-denominated securities of foreign issuers. Portfolio holdings
will be concentrated in areas of the bond market (based on quality, sector,
coupon or maturity) which the Adviser believes to be relatively undervalued.
The total rate of return for this Fund is expected to exhibit less volatility
than that of the PIMCO Long-Term U.S. Government Fund because its duration
will normally be shorter.
 
  PIMCO Total Return Fund II has the same policies as the PIMCO Total Return
Fund, except that its investments in fixed income securities are limited to
those of domestic (U.S.) issuers that are rated at least Baa by Moody's or BBB
by S&P (or, if unrated, determined by the Adviser to be of comparable
quality.)

  PIMCO Total Return Fund III has the same policies as the PIMCO Total Return
Fund, except that it limits its investments with respect to certain socially
sensitive issues in the same manner as the PIMCO Low Duration Fund III.
 
  PIMCO Commercial Mortgage Securities Fund invests at least 65% of its assets
in commercial mortgage-backed securities rated at least Baa by Moody's or BBB
by S&P (or, if unrated, determined by the Adviser to be of comparable
quality). The Fund also may invest up to 35% of its assets in lower-rated
securities (but rated at least B, or, if unrated, determined by the Adviser to
be of comparable quality) if such securities are considered by the Adviser to
have attractive investment characteristics. For information on the risks
associated with investments in securities rated below investment grade, see
"Credit and Quality Standards." The portfolio duration of this Fund will vary
within a range of from three to eight years, depending on the Adviser's view
of the potential for total return offered by a particular duration strategy.
The Fund may invest in securities of foreign issuers, but only those that are
U.S. dollar-denominated.
 
  PIMCO Long-Term U.S. Government Fund invests in a diversified portfolio of
primarily U.S. Government securities, which may be represented by futures
contracts (including related options) with respect to such securities, and
options on such securities, when the Adviser deems it appropriate to do so.
The Fund will have a minimum portfolio duration of eight years. For point of
reference, the dollar-weighted average portfolio maturity of the Fund is
expected to be more than ten years. The total rate of return is expected to
exhibit more volatility than that of the other Fixed Income Funds due to the
greater investment risk normally associated with longer duration investments.
The PIMCO Long-Term U.S. Government Fund's investments in fixed income
securities are limited to those of U.S. dollar-denominated securities of
domestic and foreign issuers that are rated at least A by Moody's or S&P (or,
if unrated, determined by the Adviser to be of comparable quality). In
addition, the Fund will not acquire a security if, as a result, more than 10%
of the Fund's total assets would be invested in securities rated below Aa by
Moody's or below AA by S&P, or if more than 25% of the Fund's total assets
would be invested in securities rated Aa by Moody's or AA by S&P.
 
  PIMCO Foreign Fund invests in a portfolio of fixed income securities
primarily denominated in major foreign currencies and baskets of foreign
currencies (such as the European Currency Unit, or "ECU"). The Adviser will
invest the assets of the Fund in a number of international bond markets so
that, under normal circumstances, the Fund will invest at least 85% of its
assets in securities of issuers located outside the United States,
representing at least three foreign countries, which may be represented by
futures contracts (including related options) with respect to such securities,
and options on such securities, when the Adviser deems it appropriate to do
so. The Fund may invest up to 10% of its assets in fixed income securities
that are rated below investment grade but rated B or higher by Moody's or S&P
(or, if unrated, determined by the Adviser to be of comparable quality). For
information on the risks associated with investments in securities rated below
investment grade, see "Credit and Quality Standards." The portfolio duration
of the Fund will vary from three to six years.
 
  PIMCO Global Fund invests in a portfolio of fixed income securities
denominated in major foreign currencies, baskets of foreign currencies (such
as the ECU), and the U.S. dollar. Under normal circumstances, at least 65% of
its assets will be invested in fixed income securities of issuers located in
at least three countries (one of which may be the United States), which may be
represented by futures contracts (including related options) with respect to
such securities, and options on such securities, when the Adviser deems it
appropriate to do so. Depending on the Adviser's current opinion as to the
proper allocation of assets among domestic and foreign issuers, investments in
the securities of issuers located outside the United States will normally vary
between 25% and 75% of the Fund's assets. The Fund may invest up to 10% of its
assets in fixed income securities that are rated below investment grade but
rated B or higher by Moody's or S&P (or, if unrated, determined by the Adviser
to be of comparable quality). For information on the risks associated with
investments in securities rated below investment grade, see "Credit and
Quality Standards." The portfolio duration of the Fund will vary from three to
eight years.
 
  The PIMCO Foreign and Global Funds differ primarily in the extent to which
assets are invested in the securities of issuers located outside the United
States. The Adviser will select the PIMCO Foreign and Global Funds' foreign
country and currency compositions based on an evaluation of relative interest
rates, exchange rates, monetary and fiscal policies, trade and current account
balances, and any other specific factors the Adviser believes to be relevant.
 
  PIMCO International Fund invests in a portfolio of fixed income securities
denominated in major foreign currencies, baskets of foreign currencies, and
the U.S. dollar. The PIMCO International Fund is available only
 
                                                                    PIMCO FUNDS

to private account clients of PIMCO. The Adviser will invest the assets of the
Fund in a number of international bond markets so that, under normal
conditions, the Fund will invest at least 65% of its assets in fixed income
securities of foreign issuers representing at least three foreign countries or
currencies, which may be represented by futures contracts (including related
options) with respect to such securities, and options on such securities, when
the Adviser deems it appropriate to do so. The PIMCO International Fund will
invest only in investment grade securities, i.e., in securities rated at least
Baa by Moody's or BBB by S&P (or, if unrated, deemed by the Adviser to be of
comparable quality). The portfolio duration of the PIMCO International Fund
will vary based on the strategy currently being used by the Adviser in
managing the assets of the Fund within the overall PIMCO private account
management program, but is not expected to exceed eight years. The Adviser
will select the Fund's foreign country and currency composition based on its
evaluation of relative interest rates, inflation rates, exchange rates,
monetary and fiscal policies, trade and current account balances, and any
other specific factors the Adviser believes to be relevant.
 
  As a non-fundamental, operating policy, the Adviser intends to use foreign
currency-related derivative instruments (currency futures and related options,
currency options, forward contracts and swap agreements) in an effort to hedge
foreign currency risk with respect to at least 75% of the assets of the Fixed
Income Funds (other than the Global Fund) denominated in currencies other than
the U.S. dollar. There can be no assurance that the Adviser will be successful
in doing so. The active use of currency derivatives involves transaction costs
which may adversely effect yield and return.
 
  The PIMCO Commercial Mortgage Securities, Foreign, Global and International
Funds are "non-diversified" for purposes of the Investment Company Act of 1940
("1940 Act"), meaning that they may invest a greater percentage of their
assets in the securities of one issuer than the other Funds. As "non-
diversified" portfolios, these Funds may be more susceptible to risks
associated with a single economic, political or regulatory occurrence than a
diversified portfolio might be.
 
INVESTMENT TECHNIQUES USED BY THE FIXED INCOME FUNDS
 
  The Fixed Income Funds, except the PIMCO Money Market Fund, may buy or sell
interest rate futures contracts, options on interest rate futures contracts
and options on fixed income securities for the purpose of hedging against
changes in the value of securities which a Fund owns or anticipates purchasing
due to anticipated changes in interest rates. All of the Fixed Income Funds
that may invest in securities denominated in foreign currencies also may
engage in foreign currency exchange transactions by means of buying or selling
foreign currencies on a spot basis, entering into foreign currency forward
contracts, and buying and selling foreign currency options, foreign currency
futures, and options on foreign currency futures. Foreign currency exchange
transactions may be entered into for the purpose of hedging against foreign
currency exchange risk arising from a Fund's investment or anticipated
investment in securities denominated in foreign currencies. The Fixed Income
Funds that may invest in securities denominated in foreign currencies also may
enter into foreign currency forward contracts and buy or sell foreign
currencies or foreign currency options for purposes of increasing exposure to
a particular foreign currency or to shift exposure to foreign currency
fluctuations from one country to another. The Fixed Income Funds, except the
PIMCO Money Market Fund, may enter into swap agreements for purposes of
attempting to obtain a particular investment return at a lower cost to the
Fund than if the Fund had invested directly in an instrument that provided
that desired return. In addition, the Fixed Income Funds may purchase and sell
securities on a when-issued or delayed-delivery basis, sell securities short
(except the PIMCO High Yield and Total Return III Funds), enter into forward
commitments to purchase securities and lend their securities to brokers,
dealers and other financial institutions to earn income. See "Characteristics
and Risks of Securities and Investment Techniques" for a description of
securities and investment techniques listed above and restrictions generally
applicable to a Fund's investment in or use of them.
 
CREDIT AND QUALITY STANDARDS
 
  Each of the PIMCO Short-Term, Low Duration, Low Duration III, Moderate
Duration, Total Return, Total Return III, Foreign, Global and StocksPLUS Funds
may invest up to 10% of its assets in fixed income securities that are rated
below "investment grade," i.e., rated below Baa by Moody's or BBB by S&P, but
at least B (or, if unrated, determined by the Adviser to be of comparable
quality). The PIMCO Commercial Mortgage Securities Fund may invest up to 35%
of its assets in such securities. Securities rated below investment grade are
described as "speculative" by both Moody's and S&P. Securities rated B are
judged to be predominately
 
<PAGE>
 
                                                                              17

speculative with respect to their capacity to pay interest and repay principal
in accordance with the terms of the obligations. The Adviser seeks to reduce
the risks associated with investing in such securities by limiting the Fund's
holdings in such securities and by the depth of its own credit analysis. The
PIMCO High Yield Fund's investments in high yield securities are discussed
separately under "Characteristics of Securities and Investment Techinques--
High Yield Securities."
 
  Certain of the Funds make use of average portfolio credit quality standards
to assist institutional investors whose own investment guidelines limit their
investments accordingly. In determining a Fund's overall dollar-weighted
average quality, unrated securities are treated as if rated, based on the
Adviser's view of their comparability to rated securities. A Fund's use of
average quality criteria is intended to be a guide for those institutional
investors whose investment guidelines require that assets be invested
according to comparable criteria. Reference to an overall average quality
rating for a Fund does not mean that all securities held by the Fund will be
rated in that category or higher. A Fund's investments may range in quality
from securities rated in the lowest category in which the Fund is permitted to
invest to securities rated in the highest category (as rated by Moody's or S&P
or, if unrated, determined by the Adviser to be of comparable quality). The
percentage of a Fund's assets invested in securities in a particular rating
category will vary. See "Appendix A--Description of Securities Ratings," for a
description of Moody's and S&P's ratings applicable to fixed income
securities.
 
TOTAL RETURN
 
  The "total return" sought by certain of the Fixed Income Funds will consist
of interest and dividends from underlying securities, capital appreciation
reflected in unrealized increases in value of portfolio securities (realized
by the shareholder only upon selling shares), or realized from the purchase
and sale of securities and use of futures and options, or gains from favorable
changes in foreign currency exchange rates. Generally, over the long term, the
total return obtained by a portfolio investing primarily in fixed income
securities is not expected to be as great as that obtained by a portfolio that
invests primarily in equity securities. At the same time, the market risk and
price volatility of a fixed income portfolio is expected to be less than that
of an equity portfolio, so that a fixed income portfolio is generally
considered to be a more conservative investment. The change in market value of
fixed income securities (and therefore their capital appreciation or
depreciation) is largely a function of changes in the current level of
interest rates. When interest rates are falling, a portfolio with a shorter
duration generally will not generate as high a level of total return as a
portfolio with a longer duration. Conversely, when interest rates are rising,
a portfolio with a shorter duration will generally outperform longer duration
portfolios. When interest rates are flat, shorter duration portfolios
generally will not generate as high a level of total return as longer duration
portfolios (assuming that long-term interest rates are higher than short-term
rates, which is commonly the case). With respect to the composition of any
fixed income portfolio, the longer the duration of the portfolio, the greater
the anticipated potential for total return, with, however, greater attendant
market risk and price volatility than for a portfolio with a shorter duration.
The market value of securities denominated in currencies other than the U.S.
dollar also may be affected by movements in foreign currency exchange rates.
 
DURATION
 
  Duration is a measure of the expected life of a fixed income security that
was developed as a more precise alternative to the concept of "term to
maturity." Duration incorporates a bond's yield, coupon interest payments,
final maturity and call features into one measure. Duration is one of the
fundamental tools used by the Adviser in portfolio selection for the Fixed
Income Funds.
 
  Traditionally, a fixed income security's "term to maturity" has been used as
a proxy for the sensitivity of the security's price to changes in interest
rates (which is the "interest rate risk" or "volatility" of the security).
However, "term to maturity" measures only the time until a fixed income
security provides its final payment, taking no account of the pattern of the
security's payments prior to maturity. Duration is a measure of the expected
life of a fixed income security on a present value basis. Duration takes the
length of the time intervals between the present time and the time that the
interest and principal payments are scheduled or, in the case of a callable
bond, expected to be received, and weights them by the present values of the
cash to be received at each future point in time. For any fixed income
security with interest payments occurring prior to the payment of principal,
duration is always less than maturity. In general, all other things being
equal, the lower the stated or
 
                                                                    PIMCO FUNDS
<PAGE>

coupon rate of interest of a fixed income security, the longer the duration of
the security; conversely, the higher the stated or coupon rate of interest of
a fixed income security, the shorter the duration of the security.
 
  Futures, options and options on futures have durations which, in general,
are closely related to the duration of the securities which underlie them.
Holding long futures or call option positions (backed by a segregated account
of cash and cash equivalents) will lengthen a Fund's duration by approximately
the same amount that holding an equivalent amount of the underlying securities
would.
 
  Short futures or put option positions have durations roughly equal to the
negative duration of the securities that underlie these positions, and have
the effect of reducing portfolio duration by approximately the same amount
that selling an equivalent amount of the underlying securities would.
 
  There are some situations where even the standard duration calculation does
not properly reflect the interest rate exposure of a security. For example,
floating and variable rate securities often have final maturities of ten or
more years; however, their interest rate exposure corresponds to the frequency
of the coupon reset. Another example where the interest rate exposure is not
properly captured by duration is the case of mortgage pass-through securities.
The stated final maturity of such securities is generally 30 years, but
current prepayment rates are more critical in determining the securities'
interest rate exposure. In these and other similar situations, the Adviser
will use more sophisticated analytical techniques that incorporate the
economic life of a security into the determination of its interest rate
exposure.
 
EQUITY FUNDS
 
  The Equity Funds are the PIMCO StocksPLUS Fund, the PIMCO Growth Stock Fund,
and the PIMCO VersaSTYLE Equity Fund. The investment objective of the PIMCO
Growth Stock Fund is to seek long-term growth of capital. The investment
objective of both the PIMCO StocksPLUS and the PIMCO VersaSTYLE Equity Funds
is to seek to achieve a total return which exceeds the total return
performance of the Standard and Poor's 500 Composite Stock Price Index
("S&P 500").
 
  Each of the Equity Funds invests in common stocks, options, futures, options
on futures and swaps consistent with its portfolio management strategy as set
forth below. Assets not invested in equity securities may be invested in
securities eligible for purchase by the Fixed Income Funds. In addition, each
of the Funds may lend its portfolio securities to brokers, dealers and other
financial institutions in order to earn income. Each of the Equity Funds may
invest all of its assets in derivative instruments, as described below and
under "Characteristics of Securities and Investment Techniques--Derivative
Instruments."
 
  Each of the PIMCO Growth Stock and PIMCO VersaSTYLE Equity Funds may invest
in other equity securities, including securities convertible into common
stocks and warrants, may invest up to 25% of its assets in the securities of
foreign issuers, primarily in the form of American Depositary Receipts (ADRs),
European Depositary Receipts (EDRs), or Global Depositary Receipts (GDRs), and
may purchase and sell options and futures on foreign currencies and enter into
forward currency contracts.
 
  The Equity Funds differ in composition or strategy as follows:
 
  PIMCO StocksPLUS Fund invests only in common stocks that are represented in
the S&P 500 ("S&P 500 stocks"), stock index futures, options on stock indexes,
and options on stock index futures that are based on the S&P 500 and swap
agreements with respect to the S&P 500 ("S&P 500 derivatives"). StocksPLUS is
the name of a proprietary portfolio management strategy which utilizes S&P 500
derivatives in addition to or in place of S&P 500 stocks to equal or exceed
the performance of the S&P 500. The Fund will seek to remain invested in S&P
500 stocks and S&P 500 derivatives even when the S&P 500 is declining.
 
  The percentage of the PIMCO StocksPLUS Fund's assets invested directly in
S&P 500 stocks will vary depending primarily on whether S&P 500 derivatives
appear, in the Adviser's opinion, overvalued or undervalued with respect to
the stocks underlying the S&P 500. The Fund may invest up to 100% of its
assets in S&P 500 derivatives. The Fund will maintain a segregated account
consisting of liquid assets, such as cash, U.S. Government securities, or high
grade debt obligations or otherwise maintain offsetting positions to cover its
open positions in S&P 500 derivatives.
 
<PAGE>
 
                                                                              19
 
  The S&P 500 is composed of 500 selected common stocks, most of which are
listed on the New York Stock Exchange. Standard and Poor's Corporation ("S&P")
chooses the stocks to be included in the S&P 500 solely on a statistical
basis. The weightings of stocks in the index are based on each stock's
relative total market value, that is, its market price per share times the
number of shares outstanding. Stocks represented currently in the S&P 500
represent approximately two-thirds of the total market value of all U.S.
common stocks. The Fund is neither sponsored by nor affiliated with S&P.
 
  When S&P 500 derivatives appear to be overvalued relative to the S&P 500,
the Fund may invest up to 100% of its assets in a "basket" of S&P 500 stocks.
The composition of this basket will be determined by standard statistical
techniques that analyze the historical correlation between the return of every
stock currently in the S&P 500 and the return on the S&P 500 itself. The
Adviser may employ fundamental stock analysis only to choose among stocks that
have already satisfied the statistical correlation tests. Stocks chosen for
the Fund are not limited to those with any particular weighting in the S&P
500.
 
  Positions in S&P 500 futures and options on futures will be entered into
only to the extent they constitute permissible positions for the Fund
according to applicable rules of the Commodity Futures Trading Commission
("CFTC"). From time to time, the Adviser may be constrained in its ability to
use S&P 500 derivatives either by requirements of the Internal Revenue Code or
by an unanticipated inability to close out positions when it would be most
advantageous to do so. A large number of investors use S&P derivatives for
both hedging and speculative purposes, and although generally this helps
guarantee a liquid market in those instruments, at times liquidity may be
limited. For more information about S&P 500 derivatives, see "Characteristics
and Risks of Securities and Investment Techniques--Derivative Instruments."
 
  PIMCO Growth Stock Fund invests primarily in a diversified, actively managed
portfolio of common stocks of domestic and foreign issuers. The Fund may
invest up to 25% of its assets in securities denominated in foreign
currencies. The Adviser's methodology of stock selection utilizes quantitative
and fundamental equity analysis to identify stocks which it believes to have
above-average market appreciation potential over a full market cycle. Such
potential may be due, for example, to superior underlying growth rates of
earnings, undervaluation of share prices, or technological advances that have
not been recognized by the market.
 
  The Adviser selects stocks from a universe of primarily growth and cyclical
growth stocks. New issues may occasionally be purchased, but generally only if
the issuer has a sufficient existing operating history to provide a basis for
the Adviser's quantitative analysis. The PIMCO Growth Stock Fund will normally
be fully invested in equity securities, although the Adviser will vary the
percentage of assets committed to the equity market based on economic and
market conditions.
 
  The PIMCO Growth Stock Fund may purchase and sell options on equity
securities, stock indexes, and foreign currencies, and for hedging purposes,
the Fund may purchase and sell stock index and foreign currency futures and
related options and enter into forward contracts for foreign currencies. See
"Characteristics and Risks of Securities and Investment Techniques" for more
details on investment practices.
 
  PIMCO VersaSTYLE Equity Fund invests primarily in common stocks of domestic
and foreign issuers. The Fund may invest up to 25% of its assets in securities
denominated in foreign currencies. Although the Adviser will vary the
percentage of assets committed to the equity market based on economic or
market conditions, the PIMCO VersaSTYLE Equity Fund will normally be fully
invested in equity securities or equity derivatives.
 
  VersaSTYLE is a proprietary portfolio management strategy that seeks to
identify the investment style or styles such as "small capitalization,"
"growth," or "value investing" that the Adviser believes are most likely to
provide superior total return at a given time. The Adviser then tailors the
Fund's investment strategy and changes the Fund's holdings in a manner
consistent with the strategy's outlook. The Adviser's methodology of stock
selection utilizes economic and other data in seeking to identify appropriate
investment styles and to select individual securities. "Small capitalization"
investing involves the purchase of securities of relatively small issuers with
little equity and few shares of common stock outstanding, which the Adviser
believes may present the potential for significant growth. Small-
capitalization stocks tend to be subject to large price fluctuations, and
therefore the potential for short-term gains and losses is greater. "Growth"
investing involves the purchase of
 
                                                                    PIMCO FUNDS

securities of issuers characterized as having relatively low ratios of book to
market value that are expected to have above-average increases in revenues and
earnings. These firms normally retain most earnings for reinvestment and
therefore pay small dividends, emphasizing growth of capital over time as
opposed to current yield or income. "Value" investing involves the purchase of
securities based more upon the value of the issuer's assets than upon
projected earnings. "Value" firms are characterized as having relatively
higher ratios of book to market value. For example, such an issuer's current
assets may exceed its total liabilities on a per share basis by more than the
market price of the stock.
 
  The Fund may take positions in individual equity and index options, index
futures and options on index futures. The Fund may purchase and sell options
and futures on foreign currencies, and may enter into forward currency
contracts. Additionally, the Fund may enter into certain over-the-counter
transactions, including swap agreements. The primary purpose of futures and
derivative positions is to hedge risks arising from current or anticipated
equity positions, or to tailor the Fund's risk profile or to achieve exposure
to particular market sectors in a manner more cost-effective than undertaking
transactions in individual equity securities. See "Characteristics and Risks
of Securities and Investment Techniques" for more details on investment
practices.
 
                            INVESTMENT RESTRICTIONS
 
  Each Fund's investment objective, as set forth under "Investment Objectives
and Policies," and the investment restrictions set forth below are fundamental
policies of the Fund and may not be changed with respect to a Fund without the
approval of a majority of the outstanding voting shares of that Fund. Under
these restrictions, a Fund may not:
 
    (1) invest in a security if, as a result of such investment, more than
  25% of its total assets (taken at market value at the time of such
  investment) would be invested in the securities of issuers in any
  particular industry, except that this restriction does not apply (a) to
  securities issued or guaranteed by the U.S. Government or its agencies or
  instrumentalities (or repurchase agreements with respect thereto) and
  (b) with respect to the Money Market Fund, to securities or obligations
  issued by U.S. banks;
 
    (2) with respect to 75% of its assets, invest in a security if, as a
  result of such investment, more than 5% of its total assets (taken at
  market value at the time of such investment) would be invested in the
  securities of any one issuer, except that this restriction does not apply
  to securities issued or guaranteed by the U.S. Government or its agencies
  or instrumentalities (This investment restriction is not applicable to the
  Commercial Mortgage Securities Fund, the Foreign Fund, the Global Fund or
  the International Fund.);
 
    (3) with respect to 75% of its assets, invest in a security if, as a
  result of such investment, it would hold more than 10% (taken at the time
  of such investment) of the outstanding voting securities of any one issuer
  (This restriction is not applicable to the Commercial Mortgage Securities
  Fund, the Foreign Fund, the Global Fund or the International Fund.);
 
    (4) purchase or sell real estate (although it may purchase securities
  secured by real estate or interests therein, or securities issued by
  companies which invest in real estate or interests therein);
 
    (5) purchase or sell commodities or commodities contracts or oil, gas or
  mineral programs. This restriction shall not prohibit a Fund, subject to
  restrictions described in this Prospectus and in the Statement of
  Additional Information, from purchasing, selling or entering into futures
  contracts, options on futures contracts, foreign currency forward
  contracts, foreign currency options, or any interest rate, securities-
  related or foreign currency-related hedging instrument, including swap
  agreements and other derivative instruments, subject to compliance with any
  applicable provisions of the federal securities or commodities laws;
 
    (6) for the High Yield, Total Return III, International and StocksPLUS
  Funds: purchase securities on margin, except for use of short-term credit
  necessary for clearance of purchases and sales of portfolio securities, but
  it may make margin deposits in connection with transactions in options,
  futures and options on futures;
 
    (7) borrow money, issue senior securities, or pledge, mortgage or
  hypothecate its assets, except that a Fund may (i) borrow from banks or
  enter into reverse repurchase agreements, or employ similar investment
  techniques, and pledge its assets in connection therewith, but only if
  immediately after each borrowing there is asset coverage of 300% and (ii)
  enter into transactions in options, futures and options on futures and
  other derivative instruments as described in this Prospectus and in the
  Statement of Additional Information (the

  deposit of assets in escrow in connection with the writing of covered put
  and call options and the purchase of securities on a when-issued or delayed
  delivery basis, collateral arrangements with respect to initial or
  variation margin deposits for futures contracts, and commitments entered
  into under swap agreements or other derivative instruments will not be
  deemed to be pledges of a Fund's assets);
 
    (8) lend any funds or other assets, except that a Fund may, consistent
  with its investment objective and policies: (a) invest in debt obligations
  including bonds, debentures or other debt securities, bankers' acceptances
  and commercial paper, even though the purchase of such obligations may be
  deemed to be the making of loans, (b) enter into repurchase agreements, and
  (c) lend its portfolio securities in an amount not to exceed one-third of
  the value of its total assets, provided such loans are made in accordance
  with applicable guidelines established by the Securities and Exchange
  Commission and the Trustees of the Trust;
 
    (9) act as an underwriter of securities of other issuers, except to the
  extent that in connection with the disposition of portfolio securities, it
  may be deemed to be an underwriter under the federal securities laws; or
 
    (10)(a) for the High Yield, Total Return III, and StocksPLUS Funds:
  maintain a short position, or purchase, write or sell puts, calls,
  straddles, spreads or combinations thereof, except as set forth in this
  Prospectus and in the Statement of Additional Information for transactions
  in options, futures, and options on futures and transactions arising under
  swap agreements or other derivative instruments;
 
        (b) for the Money Market, Short-Term, Low Duration, Low Duration II, Low
  Duration III, Moderate Duration, Total Return, Total Return II, Commercial
  Mortgage Securities, Long-Term U.S. Government, Foreign, Global,
  International, Growth Stock and VersaSTYLE Equity Funds: maintain a short
  position, or purchase, write or sell puts, calls, straddles, spreads or
  combinations thereof, except on such conditions as may be set forth in this
  Prospectus and in the Statement of Additional Information.
 
  Each Fund is also subject to the following non-fundamental restrictions and
policies (which may be changed without shareholder approval) relating to the
investment of its assets and activities. Unless otherwise indicated, a Fund
may not:
 
    (A) invest for the purpose of exercising control or management;
 
    (B) purchase securities of other investment companies, except that a Fund
  may, for temporary purposes, purchase shares of money market mutual funds,
  subject to such restrictions as may be imposed by the Investment Company
  Act of 1940 and rules thereunder, or by any State in which shares of the
  Fund are registered (collateral arrangements with respect to securities on
  loan from a Fund are not considered to involve the purchase of securities
  by the Fund and are not subject to this restriction);
 
    (C) invest more than 15% of the net assets of a Fund (10% in the case of
  the PIMCO Money Market Fund) (taken at market value at the time of the
  investment) in "illiquid securities," illiquid securities being defined to
  include securities subject to legal or contractual restrictions on resale
  (which may include private placements), repurchase agreements maturing in
  more than seven days, certain loan participation interests, fixed time
  deposits which are not subject to prepayment or provide for withdrawal
  penalties upon prepayment (other than overnight deposits), certain options
  traded over the counter that a Fund has purchased, and securities and other
  liquid assets being used to cover such options a Fund has written,
  securities for which market quotations are not readily available, or other
  securities which legally or in the Adviser's opinion may be deemed illiquid
  (other than securities issued pursuant to Rule 144A and certain commercial
  paper that PIMCO has determined to be liquid under procedures approved by
  the Board of Trustees);
 
    (D) invest in a security if, as a result of such investment, more than 5%
  of its total assets (taken at market value at the time of such investment)
  would be invested in securities of issuers (other than issuers of Federal
  agency obligations) having a record, together with predecessors or
  unconditional guarantors, of less than three years of continuous operation;
 
    (E) purchase or retain securities of any issuer if 5% of the securities
  of such issuer are owned by those officers and Directors or Trustees of the
  Trust or of the Adviser who each own beneficially more than one-half of 1%
  of its securities;
 
    (F) purchase securities for the Fund from, or sell portfolio securities
  to, any of the officers and Directors or Trustees of the Trust or of the
  Adviser;
 
                                                                     PIMCO FUNDS

    (G) for the PIMCO Money Market, Short-Term, Low Duration, Low Duration
  II, Low Duration III, Moderate Duration, Total Return, Total Return II,
  Commercial Mortgage Securities, Long-Term U.S. Government, Foreign, Global,
  Growth Stock and VersaSTYLE Equity Funds: purchase securities on margin,
  except for use of short-term credit necessary for clearance of purchases
  and sales of portfolio securities, but it may make margin deposits in
  connection with covered transactions in options, futures, options on
  futures and short positions;
 
    (H) (effective December 31, 1995) invest more than 5% of the assets of a
  Fund (taken at market value at the time of investment) in any combination
  of interest only, principal only, or inverse floating rate securities;
 
    (I) borrow money (excluding dollar rolls and reverse repurchase
  agreements, which are subject to the Funds' fundamental borrowing
  restriction), except for temporary administrative purposes, in an amount up
  to 5% of its total assets; or
 
    (J) (a) for the PIMCO Short-Term, Low Duration and Low Duration III
  Funds, invest greater than 5% of its assets in the securities of issuers
  based in Newly Industrialized Countries ("NICs"); and
 
        (b) for the remaining Fixed Income Funds, invest greater than 10% of its
  assets in the securities of issuers based in NICs.
 
  In addition, the Trust has adopted a non-fundamental policy pursuant to
which each Fund that may invest in securities denominated in foreign
currencies, except the PIMCO Global Fund, will hedge at least 75% of its
exposure to foreign currency using the techniques described in this
Prospectus. There can be no assurance that currency hedging techniques will be
successful.
 
  Unless otherwise indicated, all limitations applicable to Fund investments
apply only at the time a transaction is entered into. Any subsequent change in
a rating assigned by any rating service to a security (or, if unrated, deemed
to be of comparable quality), or change in the percentage of Fund assets
invested in certain securities or other instruments resulting from market
fluctuations or other changes in a Fund's total assets will not require a Fund
to dispose of an investment until the Adviser determines that it is
practicable to sell or close out the investment without undue market or tax
consequences to the Fund. In the event that ratings services assign different
ratings to the same security, the Adviser will determine which rating it
believes best reflects the security's quality and risk at that time, which may
be the higher of the several assigned ratings.
 
       CHARACTERISTICS AND RISKS OF SECURITIES AND INVESTMENT TECHNIQUES
 
  The following describes in greater detail different types of securities and
investment techniques used by the individual Funds, and discusses certain
concepts relevant to the investment policies of the Funds. Additional
information about the Funds' investments and investment practices may be found
in the Statement of Additional Information.
 
U.S. GOVERNMENT SECURITIES
 
  U.S. Government securities are obligations of, or guaranteed by, the U.S.
Government, its agencies or instrumentalities. The U.S. Government does not
guarantee the net asset value of the Funds' shares. Some U.S. Government
securities, such as Treasury bills, notes and bonds, and securities guaranteed
by the Government National Mortgage Association ("GNMA"), are supported by the
full faith and credit of the United States; others, such as those of the
Federal Home Loan Banks, are supported by the right of the issuer to borrow
from the U.S. Treasury; others, such as those of the Federal National Mortgage
Association ("FNMA"), are supported by the discretionary authority of the U.S.
Government to purchase the agency's obligations; and still others, such as
those of the Student Loan Marketing Association, are supported only by the
credit of the instrumentality. U.S. Government securities include securities
that have no coupons, or have been stripped of their unmatured interest
coupons, individual interest coupons from such securities that trade
separately, and evidences of receipt of such securities. Such securities may
pay no cash income, and are purchased at a deep discount from their value at
maturity. Because interest on zero coupon securities is not distributed on a
current basis but is, in effect,
 
<PAGE>
 
                                                                              23
compounded, zero coupon securities tend to be subject to greater market risk
than interest-paying securities of similar maturities. Custodial receipts
issued in connection with so-called trademark zero coupon securities, such as
CATs and TIGRs, are not issued by the U.S. Treasury, and are therefore not
U.S. Government securities, although the underlying bond represented by such
receipt is a debt obligation of the U.S. Treasury. Other zero coupon Treasury
securities (STRIPs and CUBEs) are direct obligations of the U.S. Government.
 
CORPORATE DEBT SECURITIES
 
  Corporate debt securities include corporate bonds, debentures, notes and
other similar corporate debt instruments, including convertible securities.
Debt securities may be acquired with warrants attached. Corporate income-
producing securities may also include forms of preferred or preference stock.
The rate of interest on a corporate debt security may be fixed, floating or
variable, and may vary inversely with respect to a reference rate. See
"Variable and Floating Rate Securities." The rate of return or return of
principal on some debt obligations may be linked or indexed to the level of
exchange rates between the U.S. dollar and a foreign currency or currencies.
 
  Investments in corporate debt securities that are below investment grade
(rated below Baa (Moody's) or BBB (S&P)) are described as "speculative" both
by Moody's and S&P. Such securities are sometimes referred to as "junk bonds,"
and may be subject to greater market fluctuations, less liquidity and greater
risk of loss of income or principal, including a greater possibility of
default or bankruptcy of the issuer of such securities, than are more highly
rated debt securities. Moody's also describes securities rated Baa as having
speculative characteristics. The Adviser seeks to minimize these risks through
diversification, in-depth credit analysis and attention to current
developments in interest rates and market conditions. See "Appendix A--
Description of Securities Ratings." Investments in high yield securities are
discussed separately below, see "High Yield Securities."
 
VARIABLE AND FLOATING RATE SECURITIES
 
  Variable and floating rate securities provide for a periodic adjustment in
the interest rate paid on the obligations. The terms of such obligations must
provide that interest rates are adjusted periodically based upon an interest
rate adjustment index as provided in the respective obligations. The
adjustment intervals may be regular, and range from daily up to annually, or
may be event based, such as based on a change in the prime rate.
 
  Each of the Fixed Income Funds may invest in floating rate debt instruments
("floaters"). The interest rate on a floater is a variable rate which is tied
to another interest rate, such as a money-market index or Treasury bill rate.
The interest rate on a floater resets periodically, typically every six
months. While, because of the interest rate reset feature, floaters provide a
Fund with a certain degree of protection against rises in interest rates, a
Fund will participate in any declines in interest rates as well.
 
  Each of the Fixed Income Funds, except the PIMCO Money Market Fund, may also
invest in inverse floating rate debt instruments ("inverse floaters"). The
interest rate on an inverse floater resets in the opposite direction from the
market rate of interest to which the inverse floater is indexed. An inverse
floating rate security may exhibit greater price volatility than a fixed rate
obligation of similar credit quality. The Funds have adopted a policy under
which, effective December 31, 1995, no Fund will invest more than 5% of its
net assets in any combination of inverse floater, interest only ("IO"), or
principal only ("PO") securities. See "Mortgage-Related and Other Asset-Backed
Securities" for a discussion of IOs and POs.
 
MORTGAGE-RELATED AND OTHER ASSET-BACKED SECURITIES
 
  Each Fund, except the PIMCO Money Market Fund, may invest all of its assets
in mortgage- or asset-backed securities. The value of some mortgage- or asset-
backed securities in which the Funds invest may be particularly sensitive to
changes in prevailing interest rates, and, like the other investments of the
Funds, the ability of a Fund to successfully utilize these instruments may
depend in part upon the ability of the Adviser to forecast interest rates and
other economic factors correctly.
 
                                                                     PIMCO FUNDS

  Mortgage pass-through securities are securities representing interests in
"pools" of mortgage loans secured by residential or commercial real property
in which payments of both interest and principal on the securities are
generally made monthly, in effect "passing through" monthly payments made by
the individual borrowers on the mortgage loans which underlie the securities
(net of fees paid to the issuer or guarantor of the securities). Early
repayment of principal on some mortgage-related securities (arising from
prepayments of principal due to sale of the underlying property, refinancing,
or foreclosure, net of fees and costs which may be incurred) may expose a Fund
to a lower rate of return upon reinvestment of principal. Also, if a security
subject to prepayment has been purchased at a premium, in the event of
prepayment the value of the premium would be lost. Like other fixed income
securities, when interest rates rise, the value of a mortgage-related security
generally will decline; however, when interest rates are declining, the value
of mortgage-related securities with prepayment features may not increase as
much as other fixed income securities.
 
  Payment of principal and interest on some mortgage pass-through securities
(but not the market value of the securities themselves) may be guaranteed by
the full faith and credit of the U.S. Government (in the case of securities
guaranteed by GNMA); or guaranteed by agencies or instrumentalities of the
U.S. Government (in the case of securities guaranteed by FNMA or the Federal
Home Loan Mortgage Corporation ("FHLMC"), which are supported only by the
discretionary authority of the U.S. Government to purchase the agency's
obligations). Mortgage-related securities created by non-governmental issuers
(such as commercial banks, savings and loan institutions, private mortgage
insurance companies, mortgage bankers and other secondary market issuers) may
be supported by various forms of insurance or guarantees, including individual
loan, title, pool and hazard insurance and letters of credit, which may be
issued by governmental entities, private insurers or the mortgage poolers.
 
  Collateralized Mortgage Obligations ("CMOs") are hybrid mortgage-related
instruments. Similar to a bond, interest and pre-paid principal on a CMO are
paid, in most cases, semiannually. CMOs may be collateralized by whole
mortgage loans but are more typically collateralized by portfolios of mortgage
pass-through securities guaranteed by GNMA, FHLMC, or FNMA. CMOs are
structured into multiple classes, with each class bearing a different stated
maturity. Monthly payments of principal, including prepayments, are first
returned to investors holding the shortest maturity class; investors holding
the longer maturity classes receive principal only after the first class has
been retired. CMOs that are issued or guaranteed by the U.S. Government or by
any of its agencies or instrumentalities will be considered U.S. Government
securities by the Funds, while other CMOs, even if collateralized by U.S.
Government securities, will have the same status as other privately issued
securities for purposes of applying a Fund's diversification tests.
 
  Commercial mortgage-backed securities include securities that reflect an
interest in, and are secured by, mortgage loans on commercial real property.
The market for commercial mortgage-backed securities developed more recently
and in terms of total outstanding principal amount of issues is relatively
small compared to the market for residential single-family mortgage-backed
securities. Many of the risks of investing in commercial mortgage-backed
securities reflect the risks of investing in the real estate securing the
underlying mortgage loans. These risks reflect the effects of local and other
economic conditions on real estate markets, the ability of tenants to make
loan payments, and the ability of a property to attract and retain tenants.
Commercial mortgage-backed securities may be less liquid and exhibit greater
price volatility than other types of mortgage- or asset-backed securities.
 
  Mortgage-related securities include securities other than those described
above that directly or indirectly represent a participation in, or are secured
by and payable from, mortgage loans on real property, such as CMO residuals or
stripped mortgage-backed securities ("SMBS"), and may be structured in classes
with rights to receive varying proportions of principal and interest.
 
  A common type of SMBS will have one class receiving some of the interest and
most of the principal from the mortgage assets, while the other class will
receive most of the interest and the remainder of the principal. In the most
extreme case, one class will receive all of the interest (the "IO" class),
while the other class will receive all of the principal (the principal-only or
"PO" class). The yield to maturity on an IO class is extremely sensitive to
the rate of principal payments (including prepayments) on the related
underlying mortgage assets, and a rapid rate of principal payments may have a
material adverse effect on a Fund's yield to maturity from these securities.

                                                                              25
The Funds have adopted a policy under which, effective December 31, 1995, no
Fund will invest more than 5% of its net assets in any combination of IO, PO,
or inverse floater securities. The Funds may invest in other asset-backed
securities that have been offered to investors. For a discussion of the
characteristics of some of these instruments, see the Statement of Additional
Information.
 
REPURCHASE AGREEMENTS
 
  For the purpose of achieving income, each Fund may enter into repurchase
agreements, which entail the purchase of a portfolio eligible security from a
bank or broker-dealer that agrees to repurchase the security at the Fund's
cost plus interest within a specified time (normally one day). If the party
agreeing to repurchase should default, as a result of bankruptcy or otherwise,
the Fund will seek to sell the securities which it holds, which action could
involve procedural costs or delays in addition to a loss on the securities if
their value should fall below their repurchase price. No Fund will invest more
than 15% of its net assets (taken at current market value) in repurchase
agreements maturing in more than seven days.
 
REVERSE REPURCHASE AGREEMENTS, DOLLAR ROLLS, AND OTHER BORROWINGS
 
  A reverse repurchase agreement is a form of leverage that involves the sale
of a security by a Fund and its agreement to repurchase the instrument at a
specified time and price. The Fund will maintain a segregated account
consisting of liquid assets, such as cash, U.S. Government securities or high-
grade debt obligations, maturing not later than the expiration of the reverse
repurchase agreement, to cover its obligations under reverse repurchase
agreements.
 
  A Fund may enter into dollar rolls, in which the Fund sells mortgage-backed
or other securities for delivery in the current month and simultaneously
contracts to purchase substantially similar securities on a specified future
date. In the case of dollar rolls involving mortgage-backed securities, the
mortgage-backed securities that are purchased will be of the same type and
will have the same interest rate as those sold, but will be supported by
different pools of mortgages. The Fund forgoes principal and interest paid
during the roll period on the securities sold in a dollar roll, but the Fund
is compensated by the difference between the current sales price and the lower
price for the future purchase as well as by any interest earned on the
proceeds of the securities sold. The Fund also could be compensated through
the receipt of fee income equivalent to a lower forward price. The Fund will
maintain a segregated account consisting of liquid assets, such as cash, U.S.
Government securities or high-grade debt obligations, to cover its obligations
under dollar rolls.
 
  Dollar rolls and reverse repurchase agreements will be subject to the Funds'
limitations on borrowings, which will restrict the aggregate of such
transactions (plus any other borrowings) to 33 1/3% of a Fund's total assets.
Apart from transactions involving reverse repurchase agreements and dollar
rolls, a Fund will not borrow money, except for temporary administrative
purposes, in an amount up to 5% of its total assets.
 
LOANS OF PORTFOLIO SECURITIES
 
  For the purpose of achieving income, the Funds may lend their portfolio
securities, provided: (i) the loan is secured continuously by collateral
consisting of U.S. Government securities or cash or cash equivalents (cash,
U.S. Government securities, negotiable certificates of deposit, bankers'
acceptances or letters of credit) maintained on a daily mark-to-market basis
in an amount at least equal to the current market value of the securities
loaned; (ii) the Fund may at any time call the loan and obtain the return of
the securities loaned; (iii) the Fund will receive any interest or dividends
paid on the loaned securities; and (iv) the aggregate market value of
securities loaned will not at any time exceed one-third of the total assets of
the Fund.
 
DELAYED DELIVERY TRANSACTIONS
 
  A Fund may purchase or sell securities on a when-issued or delayed delivery
basis. These transactions involve a commitment by the Fund to purchase or sell
securities for a predetermined price or yield, with payment and delivery
taking place more than seven days in the future, or after a period longer than
the customary settlement period for that type of security. When delayed
delivery purchases are outstanding, the Fund will set aside and maintain until
the settlement date in a segregated account, liquid assets, such as cash, U.S.
Government
 
                                                                     PIMCO FUNDS
<PAGE>

securities or high grade debt obligations in an amount sufficient to meet the
purchase price. Typically, no income accrues on securities purchased on a
delayed delivery basis prior to the time delivery of the securities is made,
although a Fund may earn income on securities it has deposited in a segregated
account. When purchasing a security on a delayed delivery basis, the Fund
assumes the rights and risks of ownership of the security, including the risk
of price and yield fluctuations, and takes such fluctuations into account when
determining its net asset value. Because the Fund is not required to pay for
the security until the delivery date, these risks are in addition to the risks
associated with the Fund's other investments. If the Fund remains
substantially fully invested at a time when delayed delivery purchases are
outstanding, the delayed delivery purchases may result in a form of leverage.
When the Fund has sold a security on a delayed delivery basis, the Fund does
not participate in future gains or losses with respect to the security. If the
other party to a delayed delivery transaction fails to deliver or pay for the
securities, the Fund could miss a favorable price or yield opportunity or
could suffer a loss. A Fund may dispose of or renegotiate a delayed delivery
transaction after it is entered into, and may sell when-issued securities
before they are delivered, which may result in a capital gain or loss. There
is no percentage limitation on the extent to which the Funds may purchase or
sell securities on a delayed-delivery basis.
 
SHORT SALES
 
  Certain Funds may from time to time effect short sales as part of their
overall portfolio management strategies, including the use of derivative
instruments, or to offset potential declines in value of long positions in
similar securities as those sold short. A short sale (other than a short sale
against the box) is a transaction in which a Fund sells a security it does not
own at the time of the sale in anticipation that the market price of that
security will decline. To the extent that a Fund engages in short sales, it
must (except in the case of short sales "against the box") maintain asset
coverage in the form of liquid assets, such as cash, U.S. Government
securities or high grade debt obligations in a segregated account, or
otherwise cover its position in a permissible manner. A short sale is "against
the box" to the extent that the Fund contemporaneously owns, or has the right
to obtain at no added cost, securities identical to those sold short.
 
FOREIGN SECURITIES
 
  Each of the Fixed Income Funds (except the PIMCO Low Duration II and Total
Return II Funds) may invest directly in fixed income securities of non-U.S.
issuers. The PIMCO Money Market, High Yield, Commercial Mortgage Securities
and Long-Term U.S. Government Funds may only invest in U.S. dollar-denominated
fixed income securities of non-U.S. issuers. The PIMCO Growth Stock and
VersaSTYLE Equity Funds may invest directly in foreign equity securities and
in securities represented by European Depositary Receipts ("EDRs"), American
Depositary Receipts ("ADRs") or Global Depositary 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 trade in public or
private markets in other countries.
 
  Each Fund (except the PIMCO VersaSTYLE Equity Fund) will limit its foreign
investments to securities of issuers based in developed countries (including
Newly Industrialized Countries ("NICs"), such as Taiwan, South Korea and
Mexico). The PIMCO Short-Term, Low Duration and Low Duration III Funds limit
their investments in securities of issuers based in NICs to 5% of their
assets, and the remaining Fixed Income Funds limit their investments in
securities of issuers based in NICs to 10% of their assets. Investing in the
securities of issuers in any foreign country involves special risks and
considerations not typically associated with investing in U.S. companies.
Shareholders should consider carefully the substantial risks involved in
investing in securities issued by companies and governments of foreign
nations. These risks include: differences in accounting, auditing and
financial reporting standards; generally higher commission rates on foreign
portfolio transactions; the possibility of nationalization, expropriation or
confiscatory taxation; adverse changes in investment or exchange control
regulations (which may include suspension of the ability to transfer currency
from a country); and political instability which could affect U.S. investments
in foreign countries. Additionally, 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. Additional costs associated
with an investment in

foreign securities may include higher custodial fees than apply to domestic
custodial arrangements, and transaction costs of foreign currency conversions.
Changes in foreign exchange rates also will affect the value of securities
denominated or quoted in currencies other than the U.S. dollar.
 
  The PIMCO VersaSTYLE Equity Fund may invest in the securities of issuers
based in countries with developing economies. Investing in developing
countries involves certain risks not typically associated with investing in
U.S. securities, and imposes risks greater than, or in addition to, risks of
investing in foreign, developed countries. These risks include: greater risk
of nationalization or expropriation of assets or confiscatory taxation;
currency devaluations and other currency exchange rate fluctuations; greater
social, economic and political uncertainty and instability (including the risk
of war); more substantial government involvement in the economy; higher rates
of inflation; less government supervision and regulation of the securities
markets and participants in those markets; controls on foreign investment and
limitations on repatriation of invested capital and on the Fund's ability to
exchange local currencies for U.S. dollars; unavailability of currency hedging
techniques in certain developing countries; the fact that companies in
developing countries may be smaller, less seasoned and newly organized
companies; the difference in, or lack of, auditing and financial reporting
standards, which may result in unavailability of material information about
issuers; the risk that it may be more difficult to obtain and/or enforce a
judgment in a court outside the United States; and greater price volatility,
substantially less liquidity and significantly smaller market capitalization
of securities markets.
 
  Each of the Fixed Income Funds (except the PIMCO Low Duration II and Total
Return II Funds) may invest in Brady Bonds. Brady Bonds are securities created
through the exchange of existing commercial bank loans to sovereign entities
for new obligations in connection with debt restructurings under a debt
restructuring plan introduced by former U.S. Secretary of the Treasury,
Nicholas F. Brady. Brady Bonds have been issued only recently, and for that
reason do not have a long payment history. Brady Bonds may be collateralized
or uncollateralized, are issued in various currencies (but primarily the U.S.
dollar), and are actively traded in the over-the-counter secondary market.
Brady Bonds are not considered to be U.S. Government securities. In light of
the residual risk of Brady Bonds and, among other factors, the history of
defaults with respect to commercial bank loans by public and private entities
in countries issuing Brady Bonds, investments in Brady Bonds may be viewed as
speculative. There can be no assurance that Brady Bonds acquired by a Fund
will not be subject to restructuring arrangements or to requests for new
credit, which may cause the Fund to suffer a loss of interest or principal on
any of its holdings. For further information, see the Statement of Additional
Information.
 
FOREIGN CURRENCY TRANSACTIONS
 
  Foreign currency exchange rates may fluctuate significantly over short
periods of time. They generally are determined by the forces of supply and
demand in the foreign exchange markets and the relative merits of investments
in different countries, actual or perceived changes in interest rates and
other complex factors, as seen from an international perspective. Currency
exchange rates also can be affected unpredictably by intervention by U.S. or
foreign governments or central banks or the failure to intervene, or by
currency controls or political developments in the U.S. or abroad. Currencies
in which the Funds' assets are denominated may be devalued against the U.S.
dollar, resulting in a loss to the Funds.
 
  All Funds that may invest in securities denominated in foreign currencies
may, in addition to buying and selling foreign currency futures contracts and
options on foreign currencies and foreign currency futures, enter into forward
foreign currency exchange contracts to reduce the risks of adverse changes in
foreign exchange rates. A forward foreign currency exchange contract involves
an obligation to purchase or sell a specific currency at a future date, which
may be any fixed number of days from the date of the contract agreed upon by
the parties, at a price set at the time of the contract. By entering into a
forward foreign currency contract, the Fund "locks in" the exchange rate
between the currency it will deliver and the currency it will receive for the
duration of the contract. As a result, a Fund reduces its exposure to changes
in the value of the currency it will deliver and increases its exposure to
changes in the value of the currency it will exchange into. The effect on the
value of a Fund is similar to selling securities denominated in one currency
and purchasing securities denominated in another. Contracts to sell foreign
currency would limit any potential gain which might be realized by a Fund if
the value of the hedged currency increases. A Fund may enter into these
contracts for the purpose of hedging against foreign exchange risk arising
from the Fund's investment or anticipated investment in securities denominated
in foreign currencies. A Fund also may enter into these contracts for purposes
of increasing exposure to a foreign currency or to shift exposure to foreign
currency fluctuations from one country to another.
 
                                                                     PIMCO FUNDS
<PAGE>

A Fund may use one currency (or a basket of currencies) to hedge against
adverse changes in the value of another currency (or a basket of currencies)
when exchange rates between the two currencies are positively correlated. Each
Fund that may invest in securities denominated in foreign currencies, except
the PIMCO Global Fund, will use these techniques to hedge at least 75% of its
exposure to foreign currency. A Fund will segregate liquid assets, such as
cash or high grade debt obligations in a segregated account to cover forward
currency contracts entered into for non-hedging purposes.
 
  The Funds also may invest in foreign currency exchange-related securities,
such as foreign currency warrants and other instruments whose return is linked
to foreign currency exchange rates. For a description of these instruments,
see the Statement of Additional Information.
 
HIGH YIELD SECURITIES ("JUNK BONDS")
 
  The PIMCO High Yield Fund invests at least 65% of its assets, and the PIMCO
Commercial Mortgage Securities Fund may invest up to 35% of its assets, in
fixed income securities rated lower than Baa by Moody's or lower than BBB by
S&P but rated at least B by Moody's or S&P (or, if not rated, of comparable
quality). In addition, each of the PIMCO Short-Term, Low Duration, Low
Duration III, Moderate Duration, Total Return, Total Return III, Foreign,
Global and StocksPLUS Funds may invest up to 10% of its assets in such
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. Securities
rated Baa are considered by Moody's to have some speculative characteristics.
Investors should consider the following risks associated with high yield
securities before investing in these Funds.
 
  Investing in high yield securities involves special risks in addition to the
risks associated with investments in higher rated fixed income securities.
High yield securities may be regarded as predominately speculative with
respect to the issuer's continuing ability to meet principal and interest
payments. Analysis of the creditworthiness of issuers of high yield securities
may be more complex than for issuers of higher quality debt securities, and
the ability of a Fund to achieve its investment objective may, to the extent
of its investments in high yield securities, be more dependent upon such
creditworthiness analysis than would be the case if the Fund were investing in
higher quality securities.
 
  High yield securities may be more susceptible to real or perceived adverse
economic and competitive industry conditions than higher grade securities. The
prices of high yield securities have been found to be less sensitive to
interest rate changes than more highly rated investments, but more sensitive
to adverse economic downturns or individual corporate developments. A
projection of an economic downturn or of a period of rising interest rates,
for example, could cause a decline in high yield security prices because the
advent of a recession could lessen the ability of a highly leveraged company
to make principal and interest payments on its debt securities. If the issuer
of high yield securities defaults, a Fund may incur additional expenses to
seek recovery. In the case of high yield securities structured as zero coupon
or payment-in-kind securities, the market prices of such securities are
affected to a greater extent by interest rate changes, and therefore tend to
be more volatile than securities which pay interest periodically and in cash.
 
  The secondary markets on which high yield securities are traded may be less
liquid than the market for higher grade securities. Less liquidity in the
secondary trading markets could adversely affect and cause large fluctuations
in the daily net asset value of a Fund's shares. Adverse publicity and
investor perceptions, whether or not based on fundamental analysis, may
decrease the values and liquidity of high yield securities, especially in a
thinly traded market.
 
  There may be special tax considerations associated with investing in high
yield securities structured as zero coupon or payment-in-kind securities. Each
Fund records the interest on these securities as income even though it
receives no cash interest until the security's maturity or payment date. The
Funds will be required to distribute all or substantially all such amounts
annually and may have to obtain the cash to do so by selling securities which
otherwise would continue to be held. Shareholders generally will be taxed on
these distributions.
 
<PAGE>
 
                                                                              29
 
  The use of credit ratings as the sole method of evaluating high yield
securities can involve certain risks. For example, credit ratings evaluate the
safety of principal and interest payments, not the market value risk of high
yield securities. Also, credit rating agencies may fail to change credit
ratings in a timely fashion to reflect events since the security was last
rated. The Adviser does not rely solely on credit ratings when selecting
securities for the Funds, and develops its own independent analysis of issuer
credit quality. If a credit rating agency changes the rating of a portfolio
security held by a Fund, the Fund may retain the portfolio security if the
Adviser deems it in the best interest of shareholders.
 
  During the year ended March 31, 1995, based upon the dollar-weighted average
ratings of the Funds' portfolio holdings at the end of each month in the
Funds' fiscal year, each Fund that may invest greater than 5% of its assets in
securities rated below investment grade had the following percentages of its
net assets invested in securities rated in the categories indicated as rated
by Moody's (or, if unrated, determined by the Adviser to be of comparable
quality). See "Appendix A--Description of Securities Ratings," for further
information.

represented by such figures. In addition, the categories reflect ratings by
Moody's, and ratings assigned by  S&P may not be consistent with ratings

DERIVATIVE INSTRUMENTS
 
  To the extent permitted by the investment objectives and policies of the
Funds, the Funds may, except the PIMCO Money Market Fund, purchase and write
call and put options on securities, securities indexes and foreign currencies,
and enter into futures contracts and use options on futures contracts as
further described below. The Funds also may enter into swap agreements with
respect to foreign currencies, interest rates, and securities indexes. The
Funds may use these techniques to hedge against changes in interest rates,
foreign currency exchange rates or securities prices or as part of their
overall investment strategies. The Funds may also purchase and sell options
relating to foreign currencies for purposes of increasing exposure to a
foreign currency or to shift exposure to foreign currency fluctuations from
one country to another. Each Fund will maintain segregated accounts consisting
of liquid assets, such as cash, U.S. Government securities, or other high
grade debt obligations (or, as permitted by applicable regulation, enter into
certain offsetting positions) to cover its obligations under options, futures,
and swaps to avoid leveraging of the Fund.
 
  The Funds consider derivative instruments to consist of securities or other
instruments whose value is derived from or related to the value of some other
instrument or asset, and not to include those securities whose payment of
principal and/or interest depend upon cash flows from underlying assets, such
as mortgage- or asset-backed securities. Each Fund, except the PIMCO Money
Market Fund, may invest all of its assets in derivative instruments, subject
only to the Fund's investment objective and policies. The value of some
derivative instruments in which the Funds invest may be particularly sensitive
to changes in prevailing interest rates, and, like the other investments of
the Funds, the ability of a Fund to successfully utilize these instruments may
depend in part upon the ability of the Adviser to forecast interest rates and
other economic factors correctly. If the Adviser incorrectly forecasts such
factors and has taken positions in derivative instruments contrary to
prevailing market trends, the Funds could be exposed to the risk of a loss.
 
                                                                     PIMCO FUNDS

  The Funds might not employ any of the strategies described below, and no
assurance can be given that any strategy used will succeed. If the Adviser
incorrectly forecasts interest rates, market values or other economic factors
in utilizing a derivatives strategy for a Fund, the Fund might have been in a
better position if it had not entered into the transaction at all. The use of
these strategies involves certain special risks, including a possible
imperfect correlation, or even no correlation, between price movements of
derivative instruments and price movements of related investments; the fact
that, while some strategies involving derivative instruments can reduce the
risk of loss, they can also reduce the opportunity for gain, or even result in
losses, by offsetting favorable price movements in related investments; and
the possible inability of a Fund to purchase or sell a portfolio security at a
time that otherwise would be favorable for it to do so, or the possible need
for a Fund to sell a portfolio security at a disadvantageous time, due to the
need for the Fund to maintain asset coverage or offsetting positions in
connection with transactions in derivative instruments and the possible
inability of a Fund to close out or to liquidate its derivatives positions.
 
  Options on Securities, Securities Indexes, and Currencies A Fund may
purchase put options on securities. One purpose of purchasing put options is
to protect holdings in an underlying or related security against a substantial
decline in market value. A Fund may also purchase call options on securities.
One purpose of purchasing call options is to protect against substantial
increases in prices of securities the Fund intends to purchase pending its
ability to invest in such securities in an orderly manner. A Fund may sell put
or call options it has previously purchased, which could result in a net gain
or loss depending on whether the amount realized on the sale is more or less
than the premium and other transaction costs paid on the put or call option
which is sold. A Fund may write a call or put option only if the option is
"covered" by the Fund holding a position in the underlying securities or by
other means which would permit immediate satisfaction of the Fund's obligation
as writer of the option. Prior to exercise or expiration, an option may be
closed out by an offsetting purchase or sale of an option of the same series.
 
  The Funds may write covered straddles consisting of a combination of a call
and a put written on the same underlying security. A straddle will be covered
when sufficient assets are deposited to meet the Funds' immediate obligations.
The Funds may use the same liquid assets to cover both the call and put
options where the exercise price of the call and put are the same, or the
exercise price of the call is higher than that of the put. In such cases, the
Funds will also segregate liquid assets equivalent to the amount, if any, by
which the put is "in the money."
 
  The purchase and writing of options involves certain risks. During the
option period, the covered call writer has, in return for the premium on the
option, given up the opportunity to profit from a price increase in the
underlying securities above the exercise price, but, as long as its obligation
as a writer continues, has retained the risk of loss should the price of the
underlying security decline. The writer of an option has no control over the
time when it may be required to fulfill its obligation as a writer of the
option. Once an option writer has received an exercise notice, it cannot
effect a closing purchase transaction in order to terminate its obligation
under the option and must deliver the underlying securities at the exercise
price. If a put or call option purchased by the Fund is not sold when it has
remaining value, and if the market price of the underlying security, in the
case of a put, remains equal to or greater than the exercise price or, in the
case of a call, remains less than or equal to the exercise price, the Fund
will lose its entire investment in the option. Also, where a put or call
option on a particular security is purchased to hedge against price movements
in a related security, the price of the put or call option may move more or
less than the price of the related security. There can be no assurance that a
liquid market will exist when a Fund seeks to close out an option position.
Furthermore, if trading restrictions or suspensions are imposed on the options
markets, a Fund may be unable to close out a position.
 
  Funds that invest in foreign currency-denominated securities may buy or sell
put and call options on foreign currencies. Currency options traded on U.S. or
other exchanges may be subject to position limits which may limit the ability
of a Fund to reduce foreign currency risk using such options. Over-the-counter
options differ from traded options in that they are two-party contracts with
price and other terms negotiated between buyer and seller and generally do not
have as much market liquidity as exchange-traded options. The Funds may be
required to treat as illiquid over-the-counter options purchased and
securities being used to cover certain written over-the-counter options.
 
  Swap Agreements The Funds may enter into interest rate, index, equity and
currency exchange rate swap agreements. These transactions would be entered
into in an attempt to obtain a particular return when it is considered
desirable to do so, possibly at a lower cost to the Fund than if the Fund had
invested directly in the
 
<PAGE>
 
                                                                              31
asset that yielded the desired return. Swap agreements are two-party contracts
entered into primarily by institutional investors for periods ranging from a
few weeks to more than one year. In a standard swap transaction, two parties
agree to exchange the returns (or differentials in rates of return) earned or
realized on particular predetermined investments or instruments, which may be
adjusted for an interest factor. The gross returns to be exchanged or
"swapped" between the parties are generally calculated with respect to a
"notional amount," i.e., the return on or increase in value of a particular
dollar amount invested at a particular interest rate, in a particular foreign
currency, or in a "basket" of securities representing a particular index.
Forms of swap agreements include interest rate caps, under which, in return
for a premium, one party agrees to make payments to the other to the extent
that interest rates exceed a specified rate, or "cap"; interest rate floors,
under which, in return for a premium, one party agrees to make payments to the
other to the extent that interest rates fall below a specified level, or
"floor"; and interest rate collars, under which a party sells a cap and
purchases a floor or vice versa in an attempt to protect itself against
interest rate movements exceeding given minimum or maximum levels.
 
  Most swap agreements entered into by the Funds would calculate the
obligations of the parties to the agreement on a "net basis." Consequently, a
Fund's current obligations (or rights) under a swap agreement will generally
be equal only to the net amount to be paid or received under the agreement
based on the relative values of the positions held by each party to the
agreement (the "net amount"). A Fund's current obligations under a swap
agreement will be accrued daily (offset against amounts owed to the Fund) and
any accrued but unpaid net amounts owed to a swap counterparty will be covered
by the maintenance of a segregated account consisting of liquid assets such as
cash, U.S. Government securities, or high grade debt obligations, to avoid any
potential leveraging of the Fund's portfolio. Obligations under swap
agreements so covered will not be construed to be "senior securities" for
purposes of the Funds' investment restriction concerning senior securities. A
Fund will not enter into a swap agreement with any single party if the net
amount owed or to be received under existing contracts with that party would
exceed 5% of the Fund's assets.
 
  Whether a Fund's use of swap agreements will be successful in furthering its
investment objective will depend on the Adviser's ability to predict correctly
whether certain types of investments are likely to produce greater returns
than other investments. Because they are two-party contracts and because they
may have terms of greater than seven days, swap agreements may be considered
to be illiquid investments. Moreover, a Fund bears the risk of loss of the
amount expected to be received under a swap agreement in the event of the
default or bankruptcy of a swap agreement counterparty. The Funds will enter
into swap agreements only with counterparties that meet certain standards for
creditworthiness (generally, such counterparties would have to be eligible
counterparties under the terms of the Funds' repurchase agreement guidelines).
Certain restrictions imposed on the Funds by the Internal Revenue Code may
limit the Funds' ability to use swap agreements. The swaps market is a
relatively new market and is largely unregulated. It is possible that
developments in the swaps market, including potential government regulation,
could adversely affect a Fund's ability to terminate existing swap agreements
or to realize amounts to be received under such agreements.
 
  Futures Contracts and Options on Futures Contracts The Funds may invest, as
set forth under "Investment Objectives and Policies," in interest rate futures
contracts, stock index futures contracts and foreign currency futures
contracts and options thereon ("futures options") that are traded on a United
States or foreign exchange or board of trade.
 
  There are several risks associated with the use of futures and futures
options for hedging purposes. There can be no guarantee that there will be a
correlation between price movements in the hedging vehicle and in the
portfolio securities being hedged. An incorrect correlation could result in a
loss on both the hedged securities in a Fund and the hedging vehicle so that
the portfolio return might have been greater had hedging not been attempted.
There can be no assurance that a liquid market will exist at a time when a
Fund seeks to close out a futures contract or a futures option position. Most
futures exchanges and boards of trade limit the amount of fluctuation
permitted in futures contract prices during a single day; once the daily limit
has been reached on a particular contract, no trades may be made that day at a
price beyond that limit. In addition, certain of these instruments are
relatively new and without a significant trading history. As a result, there
is no assurance that an active secondary market will develop or continue to
exist. Lack of a liquid market for any reason may prevent a
 
                                                                     PIMCO FUNDS

Fund from liquidating an unfavorable position and the Fund would remain
obligated to meet margin requirements until the position is closed.
 
  The Funds may write covered straddles consisting of a call and a put written
on the same underlying futures contract. A straddle will be covered when
sufficient assets are deposited to meet the Funds' immediate obligations. A
Fund may use the same liquid assets to cover both the call and put options
where the exercise price of the call and put are the same, or the exercise
price of the call is higher than that of the put. In such cases, the Funds
will also segregate liquid assets equivalent to the amount, if any, by which
the put is "in the money."
 
  The Funds will only enter into futures contracts or futures options which
are standardized and traded on a U.S. or foreign exchange or board of trade,
or similar entity, or quoted on an automated quotation system. Each Fund will
use financial futures contracts and related options only for "bona fide
hedging" purposes, as such term is defined in applicable regulations of the
Commodity Futures Trading Commission ("CFTC"), or, with respect to positions
in financial futures and related options that do not qualify as "bona fide
hedging" positions, will enter such non-hedging positions only to the extent
that aggregate initial margin deposits plus premiums paid by it for open
futures option positions, less the amount by which any such positions are "in-
the-money," would not exceed 5% of the Fund's total net assets.
 
ILLIQUID SECURITIES
 
  The Funds may invest up to 15% of their net assets in illiquid securities
(10% in the case of the PIMCO Money Market Fund). The term "illiquid
securities" for this purpose means securities that cannot be disposed of
within seven days in the ordinary course of business at approximately the
amount at which a Fund has valued the securities. Illiquid securities are
considered to include, among other things, written over-the-counter options,
securities or other liquid assets being used as cover for such options,
repurchase agreements with maturities in excess of seven days, certain loan
participation interests, fixed time deposits which are not subject to
prepayment or provide for withdrawal penalties upon prepayment (other than
overnight deposits), and other securities whose disposition is restricted
under the federal securities laws (other than securities issued pursuant to
Rule 144A and certain commercial paper that PIMCO has determined to be liquid
under procedures approved by the Board of Trustees).
 
                            MANAGEMENT OF THE TRUST
 
  The business affairs of the Trust are managed under the direction of the
Board of Trustees. The Trustees are Guilford C. Babcock, Thomas P. Kemp, Brent
R. Harris, Vern O. Curtis, and William J. Popejoy. Additional information
about the Trustees and the Trust's executive officers may be found in the
Statement of Additional Information under the heading "Management--Trustees
and Officers."
 
INVESTMENT ADVISER
 
  Pacific Investment Management Company ("PIMCO") serves as investment adviser
("Adviser") to the Funds pursuant to an investment advisory contract. The
Adviser is an investment counseling firm founded in 1971, and currently has
over $66 billion in assets under management. PIMCO is a subsidiary partnership
of PIMCO Advisors L.P. ("PIMCO Advisors"). A majority interest in PIMCO
Advisors is held by PIMCO Partners, G.P., a general partnership between
Pacific Investment Management Company, a California corporation and indirect
wholly owned subsidiary of Pacific Mutual Life Insurance Company ("Pacific
Mutual"), and PIMCO Partners, LLC, a limited liability company controlled by
the PIMCO Managing Directors. PIMCO's address is 840 Newport Center Drive,
Suite 360, Newport Beach, California 92660. PIMCO is registered as an
investment adviser with the Securities and Exchange Commission and as a
commodity trading advisor with the CFTC.
 
  The Adviser manages the investment and reinvestment of the assets of each
Fund. The Adviser is responsible for placing orders for the purchase and sale
of each Fund's investments directly with brokers or dealers selected by it in
its discretion. See "Portfolio Transactions."

administration agreement. PIMCO provides administrative services to the Funds,
which include clerical help and accounting, bookkeeping, internal audit
services, and certain other services required by the Funds, preparation of
reports to the Funds' shareholders and regulatory filings. In addition, PIMCO,
at its own expense, arranges for the provision of legal, audit, custody,
transfer agency and other services for the Funds, and is responsible for the
costs of registration of the Trust's shares and the printing of prospectuses
and shareholder reports for current shareholders.
 
  The Trust is responsible for the following expenses: (i) salaries and other
compensation of any of the Trust's executive officers and employees who are
not officers, directors, stockholders or employees of PIMCO or its
subsidiaries or affiliates; (ii) taxes and governmental fees; (iii) brokerage

including costs of litigation and indemnification expenses; (vii) expenses,
such as organizational expenses, which are capitalized in accordance with
generally accepted accounting principles; and (viii) any expenses allocated or
allocable to a specific class of shares, which include service fees payable
with respect to the Administrative Class shares and may include certain other
expenses as permitted by the Trust's Dual Class Plan adopted pursuant to Rule
18f-3 under the 1940 Act and subject to review and approval by the Trustees.
 
 
ADVISORY AND ADMINISTRATIVE FEES
 
  The PIMCO Funds feature fixed advisory and administrative fee rates. For
providing investment advisory and administrative services to the Funds as

  Both the investment advisory contract and administration agreement for the
Funds may be terminated by the Trustees at any time on 60 days' written
notice. The investment advisory contract may be terminated by PIMCO on 60
days' written notice. Following the expiration of the two-year period
commencing with the effectiveness of the administration agreement, it may be
terminated by PIMCO on 60 days' written notice. Following their initial two-
year terms, the investment advisory contract and administration agreement will
continue from year to year if approved by the Trustees.
 
SERVICE FEES
 
  The Trust has adopted an Administrative Services Plan and a Distribution
Plan with respect to the Administrative Class shares of each Fund. Under the
terms of each Plan, the Trust is permitted to reimburse, out of the
Administrative Class assets of each Fund, in an amount up to 0.25% on an
annual basis of the average daily net assets of that class, financial
intermediaries that provide services in connection with the distribution of
shares or administration of plans or programs that use Fund shares as their
funding medium, and to reimburse certain other distribution-related expenses.
The same entity may not receive both distribution and administrative services
fees with respect to the same assets but may with respect to separate assets
receive fees under both a Distribution Plan and Administrative Services Plan.
Fees paid pursuant to either type of Plan may be paid for shareholder service
and the maintenance of accounts and therefore may constitute "service fees"
for purposes of applicable rules of the National Association of Securities
Dealers, Inc. Each Plan has been adopted in

                                                                              35
accordance with the requirements of Rule 12b-1 under the 1940 Act and will be
administered in accordance with the provisions of that Rule, except that
shareholders will not have the voting rights set forth in Rule 12b-1 with
respect to the Administrative Services Plan that they will have with respect
to the Distribution Plan. For a more complete disclosure of the Plans and
their terms, see the Statement of Additional Information.
 
  Institutional Class shares of the Trust may also be offered through certain
brokers and financial intermediaries ("service agents") that have established
a shareholder servicing relationship with the Trust on behalf of their
customers. The Trust pays no compensation to such entities. Service agents may
impose additional or different conditions on the purchase or redemption of
Trust shares by their customers and may charge their customers transaction or
other account fees on the purchase and redemption of Trust shares. Each
service agent is responsible for transmitting to its customers a schedule of
any such fees and information regarding any additional or different conditions
regarding purchases and redemptions. Shareholders who are customers of service
agents should consult their service agent for information regarding these fees
and conditions.
 
DISTRIBUTOR
 
  Shares of the Trust are distributed through PIMCO Advisors Distribution
Company (the "Distributor"), an indirect wholly owned subsidiary of PIMCO
Advisors. The Distributor is a broker-dealer registered with the Securities
and Exchange Commission.
 
                              PURCHASE OF SHARES
 
  Each Fund offers its shares in two classes: the "Institutional Class" and
the "Administrative Class." Shares of the Institutional Class are offered
primarily for direct investment by institutional investors and high net worth
individuals. They also are offered through certain financial intermediaries
that charge their customers transaction or other fees with respect to their
customers' investment in the Funds. Shares of the Administrative Class are
offered primarily through broker-dealers, retirement plan administrators and
other financial intermediaries. Administrative Class shares pay service fees
to such entities for services they provide to shareholders of that class.
 
  Shares of either class of the Funds may be purchased at the relevant net
asset value of that class without a sales charge. The minimum initial
investment for shares of either class is $1,000,000. Shares of the PIMCO
International Fund are offered only to clients of PIMCO who maintain
separately managed private accounts.
 
INITIAL INVESTMENT
 
  An account may be opened by completing and signing a Client Registration
Application and mailing it to PIMCO Funds at the following address: 840
Newport Center Drive, Suite 360, Newport Beach, California 92660.
 
  Purchases of shares can only be made by wiring Federal funds to Investors
Fiduciary Trust Company (the "Transfer Agent"). Before wiring Federal funds,
the investor must first telephone the Trust at (800) 927-4648 to receive
instructions for wire transfer. On the telephone the following information
will be requested: name of authorized person; shareholder name; shareholder
account number; name of Fund and share class; amount being wired; and wiring
bank name.
 
  All purchase orders are effected at the relevant net asset value for that
class next determined after receipt of the purchase order. A purchase order,
together with payment in proper form, received by the Transfer Agent prior to
the close of business (4:00 p.m., Eastern Time; 3:00 p.m., Eastern Time for
the PIMCO StocksPLUS Fund) on a day the Trust is open for business will be
effected at that day's net asset value; an order received after the close of
business will be effected at the net asset value determined on the next
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, 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.
 
                                                                     PIMCO FUNDS
<PAGE>
36 
 
  With respect to the Funds whose policy is to declare dividends daily (i.e.,
each of the Fixed Income Funds except the PIMCO International Fund), if a
purchase order for shares is received prior to 12:00 noon, Eastern Time, and
payment in Federal funds is received by the Transfer Agent by the close of the
Federal funds wire on the day the purchase order is received, dividends will
accrue starting that day. If a purchase order is received after 12:00 noon,
Eastern Time, and payment in Federal funds is received by the Transfer Agent
by the close of the Federal funds wire on the day the purchase order is
received, or as otherwise agreed to by the Trust, the order will be effected
that day as of 4:00 p.m., Eastern Time, but dividends will not begin to accrue
until the following business day.
 
ADDITIONAL INVESTMENTS
 
  Additional investments may be made at any time at the relevant net asset
value for that class by calling the Trust and wiring Federal funds to the
Transfer Agent as outlined above.
 
OTHER PURCHASE INFORMATION
 
  Purchases of a Fund's 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 its 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; to waive the
minimum initial investment for certain investors; and to redeem shares if
information provided in the Client Registration Application should prove to be
incorrect in any manner judged by the Trust to be material (e.g., in a manner
such as to render the shareholder ineligible to purchase shares of the Trust).
 
  Shares of the Trust are not qualified or registered for sale in all states.
Prospective investors should inquire as to whether shares of a particular Fund
are available for offer and sale in their 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.
 
  Investors may, subject to the approval of the Trust, purchase shares of a
Fund with liquid securities that are eligible for purchase by the Fund
(consistent with such 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 the Adviser
intends to retain the security in the Fund as an investment. Assets so
purchased by a Fund 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.
 
  The offer and sale of shares of the PIMCO Money Market Fund and PIMCO Total
Return Fund II is contingent upon the consummation of a reorganization of the
Funds as series of the Trust, anticipated to take place November 1, 1995 (the
"Reorganization"). The Trust has entered into an Agreement and Plan of
Reorganization with PIMCO Advisors Institutional Funds, another registered
open-end investment company, pursuant to which two of its series, the Money
Market Fund and PIMCO Managed Bond and Income Fund, will transfer all of their
respective assets, subject to any liabilities, to two currently non-
operational series of the Trust, the PIMCO Income and Capital Preservation
Fund and the PIMCO Income and Capital Preservation Fund II, in exchange for
shares of those Funds, which are to be renamed the PIMCO Money Market Fund and
PIMCO Total Return Fund II. A non-operational series of the Trust formerly
known as the PIMCO Total Return Fund II will be liquidated prior to the
Reorganization.
 
RETIREMENT PLANS
 
  Shares of the Funds are available for purchase by retirement plans,
including Keogh plans, 401(k) plans, 403(b) plans and IRAs. 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 his order with the plan administrator, and the time the order is
forwarded to the Transfer Agent for execution.

                             REDEMPTION OF SHARES
 
REDEMPTIONS BY MAIL
 
  Shares may be redeemed by submitting a written request to PIMCO Funds, 840
Newport Center Drive, Suite 360, Newport Beach, California 92660, stating 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
 
  If an election is made on the Client Registration Application (or
subsequently in writing), redemptions of shares may be requested by calling
the Trust at (800) 927-4648, by sending a facsimile to (714) 760-4456, 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 $10,000,000 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 PIMCO and the
Transfer Agent to act on telephone instructions from any person representing
himself to be the investor, and reasonably believed by PIMCO and the Transfer
Agent to be genuine. Neither the Trust nor its Transfer Agent will 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 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 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 under the heading "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.
 
OTHER REDEMPTION INFORMATION
 
  Payment of the redemption price will ordinarily be wired to the investor's
bank one business day after the tender request in the case of the Fixed Income
Funds, and three business days after the tender request in the case of the
Equity Funds, 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 Fund may suspend the right of redemption or postpone the
payment date at times when the New York Stock Exchange is closed, or during
certain other periods as permitted under the federal securities laws.
 
  For shareholder protection, a request to change information contained in an
account registration (for example, a request to change the bank designated to
receive wire redemption proceeds) must be received in writing, signed by the
minimum number of persons designated on the Client Registration Application
that are required to effect a redemption, and accompanied by a signature
guarantee from any eligible guarantor institution, as determined in accordance
with the Trust's procedures. Shareholders should inquire as to whether a
particular institution is an eligible guarantor institution. A signature
guarantee cannot be provided by a notary public. In addition, corporations,

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 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 $10,000 ($100,000 with respect to accounts opened after January 1,
1995). 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 $10,000, or $100,000, as the case may be.
 
  The Trust agrees to redeem shares of each Fund solely in cash up to the
lesser of $250,000 or 1% of its 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 price
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. If shares are redeemed in kind, however, the
redeeming shareholder should expect to incur transaction costs upon the
disposition of the securities received in the distribution.
 
EXCHANGE PRIVILEGE
 
  Shares of a Fund may be exchanged for shares of the same class of any other
Fund based on the respective net asset values of the shares involved, except
that shares of the PIMCO International Fund are available only to private
account clients of PIMCO. An exchange may be made by following the redemption
procedure described above under "Redemptions by Mail" or, if the telephone
redemption option has been elected, by calling the Trust at (800) 927-4648.
Effective November 1, 1995, shares of a Fund may also be exchanged for shares
of the same class of a series of the PIMCO Funds: Equity Advisors Series, an
affiliated, open-end, management investment company, comprised primarily of
equity portfolios managed by the subsidiary partnerships of PIMCO Advisors.
Shareholders interested in such an exchange may request a prospectus for these
funds by contacting the PIMCO Funds: Equity Advisors Series at the same
address and telephone number as the Trust.
 
  Exchanges may be made only with respect to Funds registered in the state of
residence of the investor or where an exemption from registration is
available. An exchange order is treated the same as a redemption followed by a
purchase and may result in a capital gain or loss for tax purposes, and
special rules may apply in computing tax basis when determining gain or loss.
See "Taxation" in the Statement of Additional Information.
 
                            PORTFOLIO TRANSACTIONS
 
  Pursuant to the Advisory Contract, the Adviser places orders for the
purchase and sale of portfolio investments for the Funds' accounts with
brokers or dealers selected by it in its discretion. In effecting purchases
and sales of portfolio securities for the account of the Funds, the Adviser
will seek the best price and execution of the Funds' orders. In doing so, a
Fund may pay higher commission rates than the lowest available when the
Adviser believes it is reasonable to do so in light of the value of the
brokerage and research services provided by the broker effecting the
transaction. The Adviser also may consider sales of shares of the Trust as a
factor in the selection of broker-dealers to execute portfolio transactions
for the Trust.
 
  The Adviser manages the Funds without regard generally to restrictions on
portfolio turnover, except those imposed on its ability to engage in short-
term trading by provisions of the federal tax laws. The use of futures
contracts and other derivative instruments with relatively short maturities
may tend to exaggerate the portfolio turnover rate for some of the Funds.
Trading in fixed income securities does not generally involve the payment of
brokerage commissions, but does involve indirect transaction costs. The use of
futures contracts may involve the payment of commissions to futures commission
merchants. The higher the rate of portfolio turnover of a Fund, the higher all
these transaction costs borne by the Fund generally will be.
 
  Some securities considered for investment by the Funds may also be
appropriate for other clients served by the Adviser. If a purchase or sale of
securities consistent with the investment policies of a Fund and one or more
of these clients served by the Adviser is considered at or about the same
time, transactions in such securities will be allocated among the Fund and
clients in a manner deemed fair and reasonable by the Adviser.

                                                                              39
                                NET ASSET VALUE
 
  The net asset value per share of each class of each Fund is determined as of
the close of trading on the New York Stock Exchange (currently 4:00 p.m.,
Eastern time) by dividing the total market value of a Fund's portfolio
investments and other assets attributable to that class, less any liabilities,
by the number of total outstanding shares of that class. The net asset values
of the Institutional Class and Administrative Class of a Fund may diverge due
to the effect of rounding at the time net asset value is calculated. Net asset
value will not be determined on days on which the New York Stock Exchange is
closed.
 
  The PIMCO Money Market Fund's securities are normally valued using the
amortized cost method of valuation. This involves valuing a security at cost
on the date of acquisition and thereafter assuming a constant accretion of a
discount or amortization of a premium to maturity. See the Statement of
Additional Information for a description of certain conditions and procedures
followed by the PIMCO Money Market Fund in connection with amortized cost
valuation. For all other Funds, portfolio securities and other assets for
which market quotations are readily available are stated at market value.
Market value is determined on the basis of last reported sales prices, or if
no sales are reported, as is the case for most securities traded over-the-
counter, at the mean between representative bid and asked quotations obtained
from a quotation reporting system or from established market makers. Fixed
income securities, including those to be purchased under firm commitment
agreements (other than obligations having a maturity of 60 days or less), are
normally valued on the basis of quotes obtained from brokers and dealers or
pricing services, which take into account appropriate factors such as
institutional-sized trading in similar groups of securities, yield, quality,
coupon rate, maturity, type of issue, trading characteristics, and other
market data. Quotations of foreign securities in foreign currency are
converted to U.S. dollar equivalents using foreign exchange quotations
received from independent dealers. Short-term investments having a maturity of
60 days or less are valued at amortized cost, when the Board of Trustees
determines that amortized cost is their fair value. Certain fixed income
securities for which daily market quotations are not readily available may be
valued, pursuant to guidelines established by the Board of Trustees, with
reference to fixed income securities whose prices are more readily obtainable
and whose durations are comparable to the securities being valued. Subject to
the foregoing, other securities for which market quotations are not readily
available are valued at fair value as determined in good faith by the Board of
Trustees.
 
                      DIVIDENDS, DISTRIBUTIONS AND TAXES
 
  Shares begin earning dividends on the effective date of purchase, provided
notification deadlines are met (see "Purchase of Shares"). For the Fixed
Income Funds (other than the PIMCO International Fund), dividends are declared
daily from net investment income to shareholders of record at the close of the
previous business day, and distributed to shareholders monthly. The PIMCO
International and Equity Funds intend to declare and pay as a dividend
substantially all of their net investment income on a quarterly basis. Any net
realized capital gains from the sale of portfolio securities will be
distributed no less frequently than once yearly. Dividend and capital gain
distributions of a Fund will be reinvested in additional shares of that Fund
unless the shareholder elects to have them paid in cash. Dividends from net
investment income with respect to Administrative Class shares will be lower
than those paid with respect to Institutional Class shares, reflecting the
payment of service fees by that class.
 
  Each Fund intends to qualify as a regulated investment company annually and
to elect to be treated as a regulated investment company under the Internal
Revenue Code of 1986, as amended. As such, a Fund generally will not pay
Federal income tax on the income and gains it pays as dividends to its
shareholders. In order to avoid a 4% Federal excise tax, each Fund intends to
distribute each year substantially all of its net income and gains.
 
  Distributions received by tax-exempt shareholders will not be subject to
Federal income tax to the extent permitted under applicable tax law. To the
extent that a shareholder is not exempt from tax on Fund distributions, such
shareholder will be subject to tax on dividends received from a Fund,
regardless of whether received in cash or reinvested in additional shares.
Shareholders must treat dividends, other than capital gain dividends or
 
                                                                     PIMCO FUNDS
<PAGE>

dividends that represent a return of capital to shareholders, as ordinary
income. Dividends designated by a Fund as capital gain dividends are taxable
to shareholders as long-term capital gain except as provided by an applicable
tax exemption. Any distributions that are not from a Fund's net investment
income or net capital gain may be characterized as a return of capital to
shareholders or, in some cases, as capital gain. Certain dividends declared in
October, November, or December of a calendar year are taxable to shareholders
(who otherwise are subject to tax on dividends) as though received on December
31 of that year if paid to shareholders during January of the following
calendar year. For state income tax purposes, interest on some Federal
obligations generally is not exempt from taxation, whether received directly
by a shareholder or through distributions of investment company taxable income
(for example, interest on FNMA and GNMA Certificates). Each Fund will advise
shareholders annually of the amount and nature of the dividends paid to them.
 
  The preceding discussion relates only to Federal income tax; the
consequences under other tax laws may differ. For additional information
relating to the tax aspects of investing in a Fund, see the Statement of
Additional Information.
 
                               OTHER INFORMATION
 
CAPITALIZATION
 
  The Trust was organized as a Massachusetts business trust on February 19,
1987. The Board of Trustees may establish additional series in the future. The
capitalization of the Trust consists solely of an unlimited number of shares
of beneficial interest with a par value of $0.0001 each. When issued, shares
of the Trust are fully paid, non-assessable and freely transferable.
 
  Under Massachusetts law, shareholders could, under certain circumstances, be
held personally liable for the obligations of the Trust. However, the
Declaration of Trust disclaims liability of the shareholders, Trustees or
officers of the Trust for acts or obligations of the Trust, which are binding
only on the assets and property of the Trust, and requires that notice of the
disclaimer be given in each contract or obligation entered into or executed by
the Trust or the Trustees. The Declaration of Trust provides for
indemnification out of Trust property for all loss and expense of any
shareholder held personally liable for the obligations of the Trust. The risk
of a shareholder incurring financial loss on account of shareholder liability
is limited to circumstances in which the Trust itself would be unable to meet
its obligations and thus should be considered remote.
 
VOTING
 
  Shareholders have the right to vote in the election of Trustees and on any
and all matters on which the law or the provisions of the Declaration of Trust
states they may be entitled to vote. The Trust is not required to hold regular
annual meetings of Trust shareholders and does not intend to do so.
Shareholders of a class of shares have separate voting rights with respect to
matters that only affect that class. See "Other Information--Voting Rights" in
the Statement of Additional Information.
 
  The Declaration of Trust provides that the holders of not less than two-
thirds of the outstanding shares of the Trust may remove a person serving as
Trustee either by declaration in writing or at a meeting called for such
purpose. The Trustees are required to call a meeting for the purpose of
considering the removal of a person serving as Trustee, if requested in
writing to do so by the holders of not less than 10% of the outstanding shares
of the Trust.
 
  Shares entitle their holders to one vote per share (with proportionate
voting for fractional shares). As of July 26, 1995, Archdiocese of Los Angeles
(Los Angeles, California) owned a controlling interest (as that term is
defined in the Investment Company Act of 1940) of the PIMCO Total Return Fund
III; Optima Funds Management (Atlanta, Georgia) owned a controlling interest
of the PIMCO Long-Term U.S. Government Fund; Southern California Edison
(Rosemead, California) owned a controlling interest of the PIMCO Foreign Fund;
Georgetown University (Washington, D.C.) and Walker Art Center (Minneapolis,
Minnesota) owned controlling interests of the PIMCO Global Fund; Great Lakes
Chemical Corporation (Lafayette, Indiana) owned a controlling interest of the
PIMCO Growth Stock Fund; and Pacific Mutual Life Insurance Company (Newport

                                                                              41
Beach, California) owned a controlling interest of the PIMCO VersaSTYLE Equity
Fund. As used in this Prospectus, the phrase "vote of a majority of the
outstanding shares" of a Fund (or the Trust) means the vote of the lesser of:
(1) 67% of the shares of the Fund (or the Trust) present at a meeting if the
holders of more than 50% of the outstanding shares are present in person or by
proxy; or (2) more than 50% of the outstanding shares of the Fund (or the
Trust).
 
PERFORMANCE INFORMATION
 
  The Trust may, from time to time, include the yield and total return for
each class of shares of its Funds in advertisements or reports to shareholders
or prospective investors. Yield quotations for the PIMCO Money Market Fund may
include current yield and effective yield. Current yield will be based on
income received by a hypothetical investment over a given seven-day period
(less expenses accrued during the period) and "annualized" (i.e., assuming
that the seven-day yield would be received for 52 weeks, stated in the terms
of an annual percentage return on the investment). Effective yield for the
Fund is calculated in the manner similar to that used to calculate current
yield, but reflects the compounding effect on earnings of reinvested
dividends. For the remaining Funds, quotations of yield for a Fund or class
will be based on the investment income per share (as defined by the Securities
and Exchange Commission) during a particular 30-day (or one-month) period
(including dividends and interest), less expenses accrued during the period
("net investment income"), and will be computed by dividing net investment
income by the maximum public offering price per share on the last day of the
period. Quotations of average annual total return for a Fund or class will be
expressed in terms of the average annual compounded rate of return of a
hypothetical investment in the Fund or class over periods of one, five and ten
years (up to the life of the Fund), reflect the deduction of a proportional
share of Fund or class expenses (on an annual basis), and assume that all
dividends and distributions are reinvested when paid.
 
  The Trust also may provide current distribution information to its
shareholders in shareholder reports or other shareholder communications or in
certain types of sales literature provided to prospective investors. Current
distribution information for a particular class of a Fund will be based on
distributions for a specified period (i.e., total dividends from net
investment income), divided by the relevant class net asset value per share on
the last day of the period and annualized. The rate of current distributions
does not reflect deductions for unrealized losses from transactions in
derivative instruments such as options and futures, which may reduce total
return. Current distribution rates differ from standardized yield rates in
that they represent what a Fund class has declared and paid to shareholders as
of the end of a specified period rather than the Fund's actual net investment
income for that period.
 
  Performance information for the Trust may also be compared to various
unmanaged indices, such as the Standard & Poor's 500 Stock Index, the
S&P/BARRA Growth Index, the Lehman Brothers Aggregate Bond Index, the Donoghue
Money Market Institutional Averages, the Merrill Lynch 1 to 3 Year Treasury
Index, the Salomon Brothers World Government Benchmark Bond Index, indices
prepared by Lipper Analytical Services, and other entities or organizations
which track the performance of investment companies or investment advisers.
Unmanaged indices (i.e., other than Lipper) generally do not reflect
deductions for administrative and management costs and expenses. PIMCO may
also report to shareholders or to the public in advertisements concerning the
performance of PIMCO as adviser to clients other than the Trust, and on the
comparative performance or standing of PIMCO in relation to other money
managers. Such comparative information may be compiled or provided by
independent ratings services or by news organizations. Any performance
information, whether related to the Funds or to the Adviser, should be
considered in light of a Fund's investment objectives and policies,
characteristics and quality of the portfolio and the market conditions during
the time period indicated, and should not be considered to be representative
of what may be achieved in the future. For a description of the methods used
to determine yield and total return for the Funds, see the Statement of
Additional Information.
 
  Investment results of the Funds will fluctuate over time, and any
presentation of the Funds' total return or yield for any prior period should
not be considered as a representation of what an investor's total return or
yield may be in any future period. The Trust's Annual Report contains
additional performance information for the Funds and is available upon request
and without charge by calling (800) 927-4648 (Current Shareholders), or (800)
800-0952 (New Accounts).

                       DESCRIPTION OF SECURITIES RATINGS
 
MOODY'S INVESTORS SERVICE, INC.
 
 CORPORATE AND MUNICIPAL BOND RATINGS
 
  Aaa: Bonds that are rated Aaa are judged to be of the best quality. They
carry the smallest degree of investment risk and are generally referred to as
"gilt edge." Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements
are likely to change, such changes as can be visualized are most unlikely to
impair the fundamentally strong position of such issues.
 
  Aa: Bonds that are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known
as high grade bonds. They are rated lower than the best bonds because margins
of protection may not be as large as in Aaa securities or fluctuation of
protective elements may be of greater amplitude or there may be other elements
present that make the long-term risks appear somewhat larger than with Aaa
securities.
 
  A: Bonds that are rated A possess many favorable investment attributes and
are to be considered as upper medium grade obligations. Factors giving
security to principal and interest are considered adequate but elements may be
present that suggest a susceptibility to impairment sometime in the future.
 
  Baa: Bonds that are rated Baa are considered as medium grade obligations,
i.e., they are neither highly protected nor poorly secured. Interest payments
and principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.
 
  Ba: Bonds that are rated Ba are judged to have speculative elements; their
future cannot be considered as well assured. Often the protection of interest
and principal payments may be very moderate and thereby not well safeguarded
during both good and bad times over the future. Uncertainty of position
characterizes bonds in this class.
 
  B: Bonds that are rated B generally lack characteristics of the desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.
 
  Caa: Bonds that are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal
or interest.
 
  Ca: Bonds that are rated Ca represent obligations which are speculative in a
high degree. Such issues are often in default or have other marked
shortcomings.
 
  C: Bonds that are rated C are the lowest rated class of bonds and issues so
rated can be regarded as having extremely poor prospects of ever attaining any
real investment standing.
 
  Moody's applies numerical modifiers, 1, 2, and 3 in each generic rating
classified from Aa through B in its corporate bond rating system. The modifier
1 indicates that the security ranks in the higher end of its generic rating
category; the modifier 2 indicates a mid-range ranking; and the modifier 3
indicates that the issue ranks in the lower end of its generic rating
category.
 
 CORPORATE SHORT-TERM DEBT RATINGS
 
  Moody's short-term debt ratings are opinions of the ability of issuers to
repay punctually senior debt obligations which have an original maturity not
exceeding one year. Obligations relying upon support mechanisms such as
letters of credit and bonds of indemnity are excluded unless explicitly rated.
 
                                                                     PIMCO FUNDS
<PAGE>
A-2 
 
  Moody's employs the following three designations, all judged to be
investment grade, to indicate the relative repayment ability of rated issuers:
 
  PRIME-1: Issuers rated Prime 1 (or supporting institutions) have a superior
ability for repayment of senior short-term debt obligations. Prime-1 repayment
ability will often be evidenced by many of the following characteristics:
leading market positions in well-established industries; high rates of return
on funds employed; conservative capitalization structure with moderate
reliance on debt and ample asset protection; broad margins in earnings
coverage of fixed financial charges and high internal cash generation; and
well-established access to a range of financial markets and assured sources of
alternate liquidity.
 
  PRIME-2: Issuers rated Prime-2 (or supporting institutions) have a strong
ability for repayment of senior short-term debt obligations. This will
normally be evidenced by many of the characteristics cited above but to a
lesser degree. Earnings trends and coverage ratios, while sound, may be more
subject to variation. Capitalization characteristics, while still appropriate,
may be more affected by external conditions. Ample alternate liquidity is
maintained.
 
  PRIME-3: Issuers rated Prime-3 (or supporting institutions) have an
acceptable ability for repayment of senior short-term obligations. The effect
of industry characteristics and market compositions may be more pronounced.
Variability in earnings and profitability may result in changes in the level
of debt protection measurements and may require relatively high financial
leverage. Adequate alternate liquidity is maintained.
 
  NOT PRIME: Issuers rated Not Prime do not fall within any of the Prime
rating categories.
 
STANDARD & POOR'S CORPORATION
 
 CORPORATE AND MUNICIPAL BOND RATINGS
 
 Investment Grade
 
  AAA: Debt rated AAA has the highest rating assigned by Standard & Poor's.
Capacity to pay interest and repay principal is extremely strong.
 
  AA: Debt rated AA has a very strong capacity to pay interest and repay
principal and differs from the highest rated issues only in small degree.
 
  A: Debt rated A has a strong capacity to pay interest and repay principal
although it is somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions than debt in higher-rated categories.
 
  BBB: Debt rated BBB is regarded as having an adequate capacity to pay
interest and repay principal. Whereas it normally exhibits adequate protection
parameters, adverse economic conditions, or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than in higher-rated categories.
 
 Speculative Grade
 
  Debt rated BB, B, CCC, CC, and C is regarded as having predominantly
speculative characteristics with respect to capacity to pay interest and repay
principal. BB indicates the lease degree of speculation and C the highest.
While such debt will likely have some quality and protective characteristics,
these are outweighed by large uncertainties or major exposures to adverse
conditions.
 
  BB: Debt rated BB has less near-term vulnerability to default than other
speculative issues. However, it faces major ongoing uncertainties or exposure
to adverse business, financial, or economic conditions which could lead to
inadequate capacity to meet timely interest and principal payments. The BB
rating category is also used for debt subordinated to senior debt that is
assigned an actual or implied BBB- rating.
 
<PAGE>
 
                                                                             A-3
 
  B: Debt rated B has a greater vulnerability to default but currently has the
capacity to meet interest payments and principal repayments. Adverse business,
financial, or economic conditions will likely impair capacity or willingness
to pay interest and repay principal. The B rating category is also used for
debt subordinated to senior debt that is assigned an actual or implied BB or
BB- rating.
 
  CCC: Debt rated CCC has a currently identifiable vulnerability to default
and is dependent upon favorable business, financial, and economic conditions
to meet timely payment of interest and repayment of principal. In the event of
adverse business, financial or economic conditions, it is not likely to have
the capacity to pay interest and repay principal. The CCC rating category is
also used for debt subordinated to senior debt that is assigned an actual or
implied B or B- rating.
 
  CC: The rating CC is typically applied to debt subordinated to senior debt
that is assigned an actual or implied CCC rating.
 
  C: The rating C is typically applied to debt subordinated to senior debt
that is assigned an actual or implied CCC- debt rating. The C rating may be
used to cover a situation where a bankruptcy petition has been filed, but debt
service payments are continued.
 
  C1: The rating C1 is reserved for income bonds on which no interest is being
paid.
 
  D: Debt rated D is in payment default. The D rating category is used when
interest payments or principal payments are not made on the date due even if
the applicable grace period has not expired, unless S&P believes that such
payments will be made during such grace period. The D rating will also be used
upon the filing of a bankruptcy petition if debt service payments are
jeopardized.
 
  Plus (+) or Minus (-): The ratings from AA to CCC may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.
 
  Provisional ratings: The letter "p" indicates that the rating is
provisional. A provisional rating assumes the successful completion of the
project being financed by the debt being rated and indicates that payment of
debt service requirements is largely or entirely dependent upon the successful
and timely completion of the project. This rating, however, while addressing
credit quality subsequent to completion of the project, makes no comment on
the likelihood of, or the risk of default upon failure of, such completion.
The investor should exercise his own judgment with respect to such likelihood
and risk.
 
  r: The "r" is attached to highlight derivative, hybrid, and certain other
obligations that S&P believes may experience high volatility or high
variability in expected returns due to non-credit risks. Examples of such
obligations are: securities whose principal or interest return is indexed to
equities, commodities, or currencies; certain swaps and options; and interest
only and principal only mortgage securities.
 
  N.R.: Not rated.
 
  Debt obligations of issuers outside the United States and its territories
are rated on the same basis as domestic corporate and municipal issues. The
ratings measure the creditworthiness of the obligor but do not take into
account currency exchange and related uncertainties.
 
 COMMERCIAL PAPER RATING DEFINITIONS
 
  A Standard & Poor's commercial paper rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more
than 365 days. Ratings are graded into several categories, ranging from A for
the highest quality obligations to D for the lowest. These categories are as
follows:
 
  A-1: This highest category indicates that the degree of safety regarding
timely payment is strong. Those issues determined to possess extremely strong
safety characteristics are denoted with a plus sign (+) designation.
 
                                                                     PIMCO FUNDS
<PAGE>
A-4 
 
  A-2: Capacity for timely payment on issues with this designation is
satisfactory. However, the relative degree of safety is not as high as for
issues designated A-1.
 
  A-3: Issues carrying this designation have adequate capacity for timely
payment. They are, however, more vulnerable to the adverse effects of changes
in circumstances than obligations carrying the higher designations.
 
  B: Issues rated B are regarded as having only speculative capacity for
timely payment.
 
  C: This rating is assigned to short-term debt obligations with a doubtful
capacity for payment.
 
  D: Debt rated D is in payment default. The D rating category is used when
interest payments or principal payments are not made on the date due, even if
the applicable grace period has not expired, unless S&P believes that such
payments will be made during such grace period.
 
  A commercial paper rating is not a recommendation to purchase or sell a
security. The ratings are based on current information furnished to Standard &
Poor's by the issuer or obtained from other sources it considers reliable. The
ratings may be changed, suspended, or withdrawn as a result of changes in or
unavailability of such information.

                       INVESTMENT OBJECTIVES AND POLICIES


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

BORROWING

          A Fund may borrow for temporary administrative purposes in an amount
not exceeding five percent of the value of its total assets.  This borrowing may
be unsecured.  Some temporary borrowings are not subject to the requirements
imposed by the Investment Company Act of 1940 ("1940 Act") that otherwise
require a Fund to maintain continuous asset coverage (that is, total assets
including borrowings, less liabilities exclusive of borrowings) of 300% of the
amount borrowed.  These asset coverage limits of the 1940 Act would apply to
borrowings in excess of 5% of the Fund's total assets or borrowings made for
other than temporary administrative purposes.  If the 300% asset coverage should
decline as a result of market fluctuations or other reasons, a Fund may be
required to sell some of its portfolio holdings within three days to reduce the
debt and restore the 300% asset coverage, even though it may be disadvantageous
from an investment standpoint to sell securities at that time.  Borrowing will
tend to exaggerate the effect on net asset value of any increase or decrease in
the market value of a Fund's portfolio.  Money borrowed will be subject to
interest costs which may or may not be recovered by appreciation of the
securities purchased.  A Fund also may be required to maintain minimum average
balances in connection with such borrowing or to pay a commitment or other fee
to maintain a line of credit; either of these requirements would increase the
cost of borrowing over the stated interest rate.

          In addition to borrowing for temporary purposes, a Fund may enter into
reverse repurchase agreements and mortgage dollar rolls.  A reverse repurchase
agreement involves the sale of a portfolio-eligible security by a Fund, coupled
with its agreement to repurchase the instrument at a specified time and price.
The Fund will maintain a segregated account with its Custodian consisting of
liquid assets, such as cash, U.S. Government securities or high quality debt
securities equal (on a daily mark-to-market basis) to its obligations under
reverse repurchase agreements with broker-dealers (but not banks).  However,
reverse repurchase agreements involve the risk that the market value of
securities retained by the Fund may decline below the repurchase price of the
securities sold by the Fund which it is obligated to repurchase.  To the extent
that a Fund collateralizes its obligations under a reverse repurchase agreement,
the asset coverage requirements of the 1940 Act will not apply.  However, the
Funds may elect to impose such requirements as a matter of policy.

          A "mortgage dollar roll," is similar to reverse repurchase agreements
in certain respects.  In a "dollar roll" transaction a Fund sells a mortgage-
related security, such as a security issued by the Government National Mortgage
Association ("GNMA"), to a dealer and 

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

          A Fund's obligations under a dollar roll agreement must be covered by
liquid assets, such as cash or high quality debt securities equal in value to
the securities subject to repurchase by the Fund, maintained in a segregated
account.  To the extent that a Fund collateralizes its obligations under a
dollar roll agreement, the asset coverage requirements of the 1940 Act will not
apply to such transactions.  However, the Funds may elect to impose such limits
as a matter of policy.  Furthermore, because dollar roll transactions may be for
terms ranging between one and six months, dollar roll transactions may be deemed
"illiquid" and subject to a Fund's overall limitations on investments in
illiquid securities.

CORPORATE DEBT SECURITIES

          A Fund's investments in U.S. dollar or foreign currency-denominated
corporate debt securities of domestic or foreign issuers are limited to
corporate debt securities (corporate bonds, debentures, notes and other similar
corporate debt instruments, including convertible securities) which meet the
minimum ratings criteria set forth for the Fund, or, if unrated, are in the
Adviser's opinion comparable in quality to corporate debt securities in which
the Fund may invest.  The rate of return or return of principal on some debt
obligations may be linked or indexed to the level of exchange rates between the
U.S. dollar and a foreign currency or currencies.

          Among the corporate bonds in which the Funds may invest are
convertible securities.  A convertible security is a bond, debenture, note, or
other security that entitles the holder to acquire common stock or other equity
securities of the same or a different issuer.  A convertible security generally
entitles the holder to receive interest paid or accrued until the convertible
security matures or is redeemed, converted or exchanged.  Before conversion,
convertible securities have 

                                      -2-
<PAGE>
 
characteristics similar to nonconvertible debt securities. Convertible
securities rank senior to common stock in a corporation's capital structure and,
therefore, generally entail less risk than the corporation's common stock,
although the extent to which such risk is reduced depends in large measure upon
the degree to which the convertible security sells above its value as a fixed
income security.

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

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

          Investments in securities rated below investment grade that are
eligible for purchase by certain of the Funds (i.e., rated B or better by
                                               ----                      
Moody's or S&P), in particular, by the High Yield Fund, are described as
"speculative" by both Moody's and S&P.  Investment in lower rated corporate debt
securities ("high yield securities") generally provides greater income and
increased opportunity for capital appreciation than investments in higher
quality securities, but they also typically entail greater price volatility and
principal and income risk. These high yield securities are regarded as
predominantly speculative with respect to the issuer's continuing ability to
meet principal and interest payments. The market for these securities is
relatively new, and many of the outstanding high yield securities have not
endured a major business recession. A long-term track record on default rates,
such as that for investment grade corporate bonds, does not exist for this
market. Analysis of the creditworthiness of issuers of debt securities that are
high yield may be more complex than for issuers of higher quality debt
securities.

          High yield securities may be more susceptible to real or perceived

                                      -3-
<PAGE>
 
adverse economic and competitive industry conditions than investment grade
securities.  The prices of high yield securities have been found to be less
sensitive to interest-rate changes than higher-rated investments, but more
sensitive to adverse economic downturns or individual corporate developments.  A
projection of an economic downturn or of a period of rising interest rates, for
example, could cause a decline in high yield security prices because the advent
of a recession could lessen the ability of a highly leveraged company to make
principal and interest payments on its debt securities.  If an issuer of high
yield securities defaults, in addition to risking payment of all or a portion of
interest and principal, the Funds may incur additional expenses to seek
recovery.  In the case of high yield securities structured as zero-coupon or
pay-in-kind securities, their market prices are affected to a greater extent by
interest rate changes, and therefore tend to be more volatile than securities
which pay interest periodically and in cash.

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

PARTICIPATION ON CREDITORS COMMITTEES

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

MORTGAGE-RELATED AND OTHER ASSET-BACKED SECURITIES

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

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

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

          Government-related guarantors (i.e., not backed by the full faith and
                                         ----                                  
credit of the United States Government) include the Federal National Mortgage
Association ("FNMA") and the Federal Home Loan Mortgage Corporation ("FHLMC").
FNMA is a government-sponsored corporation owned entirely by private
stockholders.  It is subject to general regulation by the Secretary of Housing
and Urban Development.  FNMA purchases conventional (i.e., not insured or
                                                     ----                
guaranteed by any 

                                      -5-
<PAGE>
 
government agency) residential mortgages from a list of approved
seller/servicers which include state and federally chartered savings and loan
associations, mutual savings banks, commercial banks and credit unions and
mortgage bankers. Pass-through securities issued by FNMA are guaranteed as to
timely payment of principal and interest by FNMA but are not backed by the full
faith and credit of the United States Government.

          FHLMC was created by Congress in 1970 for the purpose of increasing
the availability of mortgage credit for residential housing.  It is a
government-sponsored corporation formerly owned by the twelve Federal Home Loan
Banks and now owned entirely by private stockholders.  FHLMC issues
Participation Certificates ("Pcs") which represent interests in conventional
mortgages from FHLMC's national portfolio.  FHLMC guarantees the timely payment
of interest and ultimate collection of principal, but Pcs are not backed by the
full faith and credit of the United States Government.

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

          Mortgage-backed securities that are issued or guaranteed by the U.S.
Government, its agencies or instrumentalities, are not subject to the Funds'
industry concentration restrictions, set forth below under 

                                      -6-
<PAGE>
 
"Investment Restrictions," by virtue of the exclusion from that test available
to all U.S. Government securities. In the case of privately issued mortgage-
related securities, the Funds take the position that mortgage-related securities
do not represent interests in any particular "industry" or group of industries.
The assets underlying such securities may be represented by a portfolio of first
lien residential mortgages (including both whole mortgage loans and mortgage
participation interests) or portfolios of mortgage pass-through securities
issued or guaranteed by GNMA, FNMA or FHLMC. Mortgage loans underlying a
mortgage-related security may in turn be insured or guaranteed by the FHA or the
VA. In the case of private issue mortgage-related securities whose underlying
assets are neither U.S. Government securities nor U.S. Government-insured
mortgages, to the extent that real properties securing such assets may be
located in the same geographical region, the security may be subject to a
greater risk of default than other comparable securities in the event of adverse
economic, political or business developments that may affect such region and,
ultimately, the ability of residential homeowners to make payments of principal
and interest on the underlying mortgages.

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

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

          In a typical CMO transaction, a corporation ("issuer") issues multiple
series (e.g., A, B, C, Z) of CMO bonds ("Bonds").  Proceeds of the Bond offering
        ----                                                                    
are used to purchase mortgages or mortgage pass-through certificates
("Collateral").  The Collateral is pledged to a third party trustee as security
for the Bonds.  Principal and interest payments from the Collateral are used to
pay principal on the Bonds in the order A, B, C, Z.  The Series A, B, and C
Bonds all bear current interest.  Interest on the Series Z Bond is accrued and
added to principal and a like amount is paid as principal on the Series A, B, or

                                      -7-
<PAGE>
 
C Bond currently being paid off.  When the Series A, B, and C Bonds are paid in
full, interest and principal on the Series Z Bond begins to be paid currently.
With some CMOs, the issuer serves as a conduit to allow loan originators
(primarily builders or savings and loan associations) to borrow against their
loan portfolios.

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

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

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

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

                                      -8-
<PAGE>
 
greater price volatility than other types of mortgage- or asset-backed
securities.

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

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

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

          CMO residuals are generally purchased and sold by institutional
investors through several investment banking firms acting as brokers or dealers.
The CMO residual market has only very recently developed and CMO residuals
currently may not have the liquidity of other more

                                      -9-
<PAGE>
 
established securities trading in other markets. Transactions in CMO residuals
are generally completed only after careful review of the characteristics of the
securities in question. In addition, CMO residuals may, or pursuant to an
exemption therefrom, may not have been registered under the Securities Act of
1933, as amended. CMO residuals, whether or not registered under such Act, may
be subject to certain restrictions on transferability, and may be deemed
"illiquid" and subject to a Fund's limitations on investment in illiquid
securities.

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

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

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

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

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

FOREIGN SECURITIES

          All Funds (except the PIMCO Low Duration II and Total Return II Funds)
may invest in U.S. dollar- or foreign currency-denominated corporate debt
securities of foreign issuers (including preferred or preference stock), certain
foreign bank obligations (see "Bank Obligations") and U.S. dollar- or foreign
currency-denominated obligations of foreign governments or their subdivisions,
agencies and instrumentalities, international agencies and supranational
entities.  The PIMCO Money Market, High Yield, Commercial Mortgage Securities
and Long-Term U.S. Government Funds may invest in securities of foreign issuers
only if they are U.S. dollar-denominated.  The PIMCO Growth Stock Fund and the
PIMCO VersaSTYLE Equity Fund may invest up to 25% of its total assets directly
in common stocks issued by foreign companies or in securities represented by
European Depositary Receipts ("EDRs"), American Depositary Receipts ("ADRs") or
Global Depositary Receipts ("GDRs").  Each of the Fixed Income Funds permitted
to invest in foreign securities, except the PIMCO Foreign, Global and
International Funds, will limit its investment in securities denominated in
foreign currencies to no more than 20% of the Fund's total assets.  Effective
December 31, 1995, the PIMCO Short-Term Fund will limit its investment in
securities denominated in foreign currencies to no more than 5% of the Fund's
total assets.  Each of the Funds, except the PIMCO VersaSTYLE Equity Fund, will
limit its foreign investments to securities of issuers based in developed
countries (which include Newly Industrialized Countries ("NICs") such as Mexico,
Taiwan and South Korea).  The PIMCO Short-Term, Low Duration and Low Duration
III Funds limit their investments in securities of issuers based in NICs to 5%
of their assets, and the remaining Fixed Income Funds limit their investments in
securities of issuers based in NICs to 10% of their assets.  Investing in the
securities of foreign issuers involves special risks and considerations not
typically associated with investing in U.S. companies.  These include:
differences in accounting, auditing and financial reporting standards, generally
higher commission rates on foreign portfolio transactions, the possibility of
expropriation or confiscatory taxation, adverse changes in investment or
exchange control regulations (which may include suspension of the ability to
transfer currency from a country), political instability which can affect U.S.
investments in foreign countries and potential restrictions on the flow of
international capital.  In addition, foreign securities and dividends and
interest payable on those securities may be subject to foreign taxes, including
taxes withheld from payments on those securities.  Foreign securities often
trade with less frequency and volume than domestic securities and therefore may
exhibit greater price volatility.  Changes in foreign exchange rates will affect
the value of those securities which are denominated or quoted in currencies
other than the U.S. dollar.

          The PIMCO VersaSTYLE Equity Fund may invest in the securities of

                                      -12-
<PAGE>
 
issuers based in developing countries.  Investing in developing countries
involves certain risks not typically associated with investing in U.S.
securities, and imposes risks greater than, or in addition to, risks of
investing in foreign, developed countries.  These risks include: greater risks
of nationalization or expropriation of assets or confiscatory taxation; currency
devaluations and other currency exchange rate fluctuations; greater social,
economic and political uncertainty and instability (including the risk of war);
more substantial government involvement in the economy; higher rates of
inflation; less government supervision and regulation of the securities markets
and participants in those markets; controls on foreign investment and
limitations on repatriation of invested capital and on the Fund's ability to
exchange local currencies for U.S. dollars; unavailability of currency hedging
techniques in certain developing countries; the fact that companies in
developing countries may be smaller, less seasoned and newly organized
companies; the difference in, or lack of, auditing and financial reporting
standards, which may result in unavailability of material information about
issuers; the risk that it may be more difficult to obtain and/or enforce a
judgment in a court outside the United States; and greater price volatility,
substantially less liquidity and significantly smaller market capitalization of
securities markets.

          The PIMCO Growth Stock Fund and the PIMCO VersaSTYLE Equity Fund may
invest in securities represented by EDRs, ADRs or 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 trade in public or private markets in
other countries.  ADRs, EDRs and GDRs may be issued as sponsored or unsponsored
programs.  In sponsored programs, an issuer has made arrangements to have its
securities trade in the form of ADRs, EDRs or GDRs.  In unsponsored programs,
the issuer may not be directly involved in the creation of the program.
Although regulatory requirements with respect to sponsored and unsponsored
programs are generally similar, in some cases it may be easier to obtain
financial information from an issuer that has participated in the creation of a
sponsored program.

          All Funds that may invest in foreign currency-denominated securities
also may purchase and sell foreign currency options and foreign currency futures
contracts and related options (see "Derivative Instruments"), and enter into
forward foreign currency exchange contracts in order to protect against
uncertainty in the level of future foreign exchange rates in the purchase and
sale of securities. The Funds may also use foreign currency options and foreign
currency forward contracts to increase exposure to a foreign currency or to
shift exposure to foreign currency fluctuations from one country to another.

                                      -13-
<PAGE>
 
          A forward foreign currency contract involves an obligation to purchase
or sell a specific currency at a future date, which may be any fixed number of
days from the date of the contract agreed upon by the parties, at a price set at
the time of the contract.  These contracts may be bought or sold to protect a
Fund against a possible loss resulting from an adverse change in the
relationship between foreign currencies and the U.S. dollar or to increase
exposure to a particular foreign currency.  Open positions in forward contracts
used for non-hedging purposes will be covered by the segregation with the
Trust's custodian of liquid assets, such as cash, U.S. Government securities and
high quality short-term investments and are marked to market daily.  Although
forward contracts are intended to minimize the risk of loss due to a decline in
the value of the hedged currencies, at the same time, they tend to limit any
potential gain which might result should the value of such currencies increase.

          Each of the Fixed Income Funds (except the PIMCO Low Duration II and
Total Return II Funds) may invest in Brady Bonds.  Brady Bonds are securities
created through the exchange of existing commercial bank loans to sovereign
entities for new obligations in connection with debt restructurings under a debt
restructuring plan introduced by former U.S. Secretary of the Treasury, Nicholas
F. Brady (the "Brady Plan").  Brady Plan debt restructurings have been
implemented in several countries, including in Argentina, Bulgaria, Costa Rica,
the Dominican Republic, Jordan, Mexico, Nigeria, the Philippines, Uruguay, and
Venezuela.  In addition, Brazil has concluded a Brady-like plan.  Ecuador has
reached an agreement with its lending banks, but the full consummation of
Ecuador's Brady Plan is still pending.  It is expected that other countries will
undertake a Brady Plan in the future, including Panama, Peru, and Poland.

          Brady Bonds have been issued only recently, and accordingly do not
have a long payment history.  Brady Bonds may be collateralized or
uncollateralized, are issued in various currencies (primarily the U.S. dollar)
and are actively traded in the over-the-counter secondary market.

          U.S. dollar-denominated, collateralized Brady Bonds, which may be
fixed rate par bonds or floating rate discount bonds, are generally
collateralized in full as to principal by U.S. Treasury zero coupon bonds having
the same maturity as the Brady Bonds.  Interest payments on these Brady Bonds
generally are collateralized on a one-year or longer rolling-forward basis by
cash or securities in an amount that, in the case of fixed rate bonds, is equal
to at least one year of interest payments or, in the case of floating rate
bonds, initially is equal to at least one year's interest payments based on the
applicable interest rate at that time and is adjusted at regular intervals
thereafter. Certain Brady Bonds are entitled to "value recovery payments" in
certain circumstances, which in effect constitute

                                      -14-
<PAGE>
 
supplemental interest payments but generally are not collateralized. Brady Bonds
are often viewed as having three or four valuation components: (i) the
collateralized repayment of principal at final maturity; (ii) the collateralized
interest payments; (iii) the uncollateralized interest payments; and (iv) any
uncollateralized repayment of principal at maturity (these uncollateralized
amounts constitute the "residual risk").

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

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

FOREIGN CURRENCY EXCHANGE-RELATED SECURITIES

                                      -16-
<PAGE>
 
          FOREIGN CURRENCY WARRANTS.  Foreign currency warrants such as Currency
          -------------------------                                             
Exchange Warrants/SM/("CEWs/SM/") are warrants which entitle the holder to
receive from their issuer an amount of cash (generally, for warrants issued in
the United States, in U.S. dollars) which is calculated pursuant to a
predetermined formula and based on the exchange rate between a specified foreign
currency and the U.S. dollar as of the exercise date of the warrant.  Foreign
currency warrants generally are exercisable upon their issuance and expire as of
a specified date and time.  Foreign currency warrants have been issued in
connection with U.S. dollar-denominated debt offerings by major corporate
issuers in an attempt to reduce the foreign currency exchange risk which, from
the point of view of prospective purchasers of the securities, is inherent in
the international fixed-income marketplace. Foreign currency warrants may
attempt to reduce the foreign exchange risk assumed by purchasers of a security
by, for example, providing for a supplemental payment in the event that the U.S.
dollar depreciates against the value of a major foreign currency such as the
Japanese Yen or German Deutschmark. The formula used to determine the amount
payable upon exercise of a foreign currency warrant may make the warrant
worthless unless the applicable foreign currency exchange rate moves in a
particular direction (e.g., unless the U.S. dollar appreciates or depreciates
                      ----
against the particular foreign currency to which the warrant is linked or
indexed). Foreign currency warrants are severable from the debt obligations with
which they may be offered, and may be listed on exchanges. Foreign currency
warrants may be exercisable only in certain minimum amounts, and an investor
wishing to exercise warrants who possesses less than the minimum number required
for exercise may be required either to sell the warrants or to purchase
additional warrants, thereby incurring additional transaction costs. In the case
of any exercise of warrants, there may be a time delay between the time a holder
of warrants gives instructions to exercise and the time the exchange rate
relating to exercise is determined, during which time the exchange rate could
change significantly, thereby affecting both the market and cash settlement
values of the warrants being exercised. The expiration date of the warrants may
be accelerated if the warrants should be delisted from an exchange or if their
trading should be suspended permanently, which would result in the loss of any
remaining "time value" of the warrants (i.e., the difference between the current
                                        ----
market value and the exercise value of the warrants), and, in the case the
warrants were "out-of-the-money," in a total loss of the purchase price of the
warrants. Warrants are generally unsecured obligations of their issuers and are
not standardized foreign currency options issued by the Options Clearing
Corporation ("OCC"). Unlike foreign currency options issued by OCC, the terms of
foreign exchange warrants generally will not be amended in the event of
governmental or regulatory actions affecting exchange rates or in the event of
the imposition of other regulatory controls affecting the international currency
markets. The initial public offering price of foreign currency warrants is
generally considerably

                                      -17-
<PAGE>
 
in excess of the price that a commercial user of foreign currencies might pay in
the interbank market for a comparable option involving significantly larger
amounts of foreign currencies. Foreign currency warrants are subject to
significant foreign exchange risk, including risks arising from complex
political or economic factors.

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

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

BANK OBLIGATIONS

          Bank obligations in which the Funds invest include certificates of
deposit, bankers' acceptances, and fixed time deposits.

                                      -18-
<PAGE>
 
          Certificates of deposit are negotiable certificates issued against
funds deposited in a commercial bank for a definite period of time and earning a
specified return. Bankers' acceptances are negotiable drafts or bills of
exchange, normally drawn by an importer or exporter to pay for specific
merchandise, which are "accepted" by a bank, meaning, in effect, that the bank
unconditionally agrees to pay the face value of the instrument on maturity.
Fixed time deposits are bank obligations payable at a stated maturity date and
bearing interest at a fixed rate. Fixed time deposits may be withdrawn on demand
by the investor, but may be subject to early withdrawal penalties which vary
depending upon market conditions and the remaining maturity of the obligation.
There are no contractual restrictions on the right to transfer a beneficial
interest in a fixed time deposit to a third party, although there is no market
for such deposits. A Fund will not invest in fixed time deposits which (1) are
not subject to prepayment or (2) provide for withdrawal penalties upon
prepayment (other than overnight deposits) if, in the aggregate, more than 15%
of its net assets would be invested in such deposits, repurchase agreements
maturing in more than seven days and other illiquid assets.

          Each Fund limits its investments in United States bank obligations to
obligations of United States banks (including foreign branches) which have more
than $1 billion in total assets at the time of investment and are members of the
Federal Reserve System or are examined by the Comptroller of the Currency or
whose deposits are insured by the Federal Deposit Insurance Corporation.  A Fund
also may invest in certificates of deposit of savings and loan associations
(federally or state chartered and federally insured) having total assets in
excess of $1 billion.

          Each Fund (except the PIMCO Money Market, High Yield, Commercial
Mortgage Securities and Long-Term U.S. Government Funds) limits its investments
in foreign bank obligations to United States dollar-or foreign currency-
denominated obligations of foreign banks (including United States branches of
foreign banks) which at the time of investment (i) have more than $10 billion,
or the equivalent in other currencies, in total assets; (ii) in terms of assets
are among the 75 largest foreign banks in the world; (iii) have branches or
agencies (limited purpose offices which do not offer all banking services) in
the United States; and (iv) in the opinion of the Adviser, are of an investment
quality comparable to obligations of United States banks in which the Funds may
invest.  The PIMCO Money Market, High Yield, Commercial Mortgage Securities and
Long-Term U.S. Government Funds may invest in the same types of bank obligations
as the other Funds, but they must be U.S. dollar-denominated.  Subject to the
Trust's limitation on concentration of no more than 25% of its assets in the
securities of issuers in a particular industry, there is no limitation on the
amount of a Fund's assets which may be invested in obligations of foreign banks
which meet the conditions set forth herein.

                                      -19-
<PAGE>
 
          Obligations of foreign banks involve somewhat different investment
risks than those affecting obligations of United States banks, including the
possibilities that their liquidity could be impaired because of future political
and economic developments, that their obligations may be less marketable than
comparable obligations of United States banks, that a foreign jurisdiction might
impose withholding taxes on interest income payable on those obligations, that
foreign deposits may be seized or nationalized, that foreign governmental
restrictions such as exchange controls may be adopted which might adversely
affect the payment of principal and interest on those obligations and that the
selection of those obligations may be more difficult because there may be less
publicly available information concerning foreign banks or the accounting,
auditing and financial reporting standards, practices and requirements
applicable to foreign banks may differ from those applicable to United States
banks.  Foreign banks are not generally subject to examination by any United
States Government agency or instrumentality.

LOAN PARTICIPATIONS

          Each Fund may purchase participations in commercial loans. Such
indebtedness may be secured or unsecured.  Loan participations typically
represent direct participation in a loan to a corporate borrower, and generally
are offered by banks or other financial institutions or lending syndicates.
When purchasing loan participations, a Fund assumes the credit risk associated
with the corporate borrower and may assume the credit risk associated with an
interposed bank or other financial intermediary.  The participation interests in
which a Fund intends to invest may not be rated by any nationally recognized
rating service.

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

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

                                      -20-
<PAGE>
 
bank for the benefit of a Fund were determined to be subject to the claims of
the agent bank's general creditors, the Fund might incur certain costs and
delays in realizing payment on a loan or loan participation and could suffer a
loss of principal and/or interest. In situations involving other interposed
financial institutions (e.g., an insurance company or governmental agency)
                        ----
similar risks may arise.

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

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

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

          Loans and other types of direct indebtedness may not be readily
marketable and may be subject to restrictions on resale.  In some cases,
negotiations involved in disposing of indebtedness may require weeks to
complete.  Consequently, some indebtedness may be difficult or

                                      -21-
<PAGE>
 
impossible to dispose of readily at what the Adviser believes to be a fair
price. In addition, valuation of illiquid indebtedness involves a greater degree
of judgment in determining a Fund's net asset value than if that value were
based on available market quotations, and could result in significant variations
in the Fund's daily share price. At the same time, some loan interests are
traded among certain financial institutions and accordingly may be deemed
liquid. As the market for different types of indebtedness develops, the
liquidity of these instruments is expected to improve. In addition, the Funds
currently intend to treat indebtedness for which there is no readily available
market as illiquid for purposes of the Funds' 15% limitation on illiquid
investments.

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

SHORT SALES

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

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

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

                                      -22-
<PAGE>
 
          To the extent that a Fund engages in short sales, it will provide
collateral to the broker-dealer and (except in the case of short sales "against
the box") will maintain additional asset coverage in the form of liquid assets,
such as cash, U.S. Government securities or high grade debt obligations in a
segregated account.  The Funds do not intend to enter into short sales (other
than those "against the box") if immediately after such sale the aggregate of
the value of all collateral plus the amount in such segregated account exceeds
one-third of the value of the Fund's net assets.  This percentage may be varied
by action of the Trustees.  A short sale is "against the box" to the extent that
the Fund contemporaneously owns, or has the right to obtain at no added cost,
securities identical to those sold short.  The Funds will engage in short
selling to the extent permitted by the 1940 Act and rules and interpretations
thereunder.

          As an operating policy, the Trust has agreed with a state securities
commission that the dollar amount of short sales (other than short sales against
the box) at any time shall not exceed 25%  of the net equity of a Fund, and the
value of securities of any one issuer in which a Fund is short shall not exceed
2% of the Fund's net assets or 2% of the securities of any class of any issuer.

DERIVATIVE INSTRUMENTS

          In pursuing their individual objectives the Funds may, as described in
the Prospectus, purchase and sell (write) both put options and call options on
securities, securities indexes, and foreign currencies, and enter into interest
rate, foreign currency and index futures contracts and purchase and sell options
on such futures contracts ("futures options") for hedging purposes, except that
those Funds that may not invest in foreign currency-denominated securities may
not enter into transactions involving currency futures or options.  The Funds
also may purchase and sell foreign currency options for purposes of increasing
exposure to a foreign currency or to shift exposure to foreign currency
fluctuations from one country to another.  The Funds also may enter into swap
agreements with respect to foreign currencies, interest rates and indexes of
securities.  The Funds may invest in structured notes.  If other types of
financial instruments, including other types of options, futures contracts, or
futures options are traded in the future, a Fund may also use those instruments,
provided that the Trustees determine that their use is consistent with the
Fund's investment objective, and provided that their use is consistent with
restrictions applicable to options and futures contracts currently eligible for
use by the Trust (i.e., that written call or put options will be "covered" or
                  ----
"secured" and that futures and futures options will be used only for hedging
purposes).

          OPTIONS ON SECURITIES AND INDEXES.  A Fund may, as specified for 
          --------------------------------- 

                                      -23-
<PAGE>
 
the Fund in the Prospectus, purchase and sell both put and call options on fixed
income or other securities or indexes in standardized contracts traded on
foreign or domestic securities exchanges, boards of trade, or similar entities,
or quoted on NASDAQ or on a regulated foreign over-the-counter market, and
agreements, sometimes called cash puts, which may accompany the purchase of a
new issue of bonds from a dealer.

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

          A Fund will write call options and put options only if they are
"covered."  In the case of a call option on a security, the option is "covered"
if the Fund owns the security underlying the call or has an absolute and
immediate right to acquire that security without additional cash consideration
(or, if additional cash consideration is required, cash or other liquid assets
such as U.S. Government securities or high grade debt obligations in such amount
are placed in a segregated account by its custodian) upon conversion or exchange
of other securities held by the Fund.  For a call option on an index, the option
is covered if the Fund maintains with its custodian liquid assets such as cash,
U.S. Government securities or high grade debt obligations in an amount equal to
the contract value of the index.  A call option is also covered if the Fund
holds a call on the same security or index as the call written where the
exercise price of the call held is (i) equal to or less than the exercise price
of the call written, or (ii) greater than the exercise price of the call
written, provided the difference is maintained by the Fund in liquid assets such
as cash, U.S. Government securities or high grade debt obligations in a
segregated account with its custodian. A put option on a security or an index is
"covered" if the Fund maintains liquid assets such as cash, U.S. Government
securities or high grade debt obligations equal to the exercise price in a
segregated account with its custodian. A put option is also covered if the Fund
holds a put on the same security or index as the put written where the exercise
price of the put held is (i) equal to or greater than the exercise price of the
put written, or (ii) less than the exercise price of the put written, provided
the difference is maintained by the Fund in cash or cash equivalents in a

                                      -24-
<PAGE>
 
segregated account with its custodian.

          If an option written by a Fund expires, the Fund realizes a capital
gain equal to the premium received at the time the option was written.  If an
option purchased by a Fund expires unexercised, the Fund realizes a capital loss
equal to the premium paid.

          Prior to the earlier of exercise or expiration, an option may be
closed out by an offsetting purchase or sale of an option of the same series
(type, exchange, underlying security or index, exercise price, and expiration).
There can be no assurance, however, that a closing purchase or sale transaction
can be effected when the Fund desires.

          A Fund will realize a capital gain from a closing purchase transaction
if the cost of the closing option is less than the premium received from writing
the option, or, if it is more, the Fund will realize a capital loss.  If the
premium received from a closing sale transaction is more than the premium paid
to purchase the option, the Fund will realize a capital gain or, if it is less,
the Fund will realize a capital loss.  The principal factors affecting the
market value of a put or a call option include supply and demand, interest
rates, the current market price of the underlying security or index in relation
to the exercise price of the option, the volatility of the underlying security
or index, and the time remaining until the expiration date.

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

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

          RISKS ASSOCIATED WITH OPTIONS ON SECURITIES AND INDEXES.  There are
          -------------------------------------------------------            
several risks associated with transactions in options on securities and on
indexes.  For example, there are significant differences between the securities
and options markets that could result in an imperfect correlation between these
markets, causing a given transaction not to

                                      -25-
<PAGE>
 
achieve its objectives. A decision as to whether, when and how to use options
involves the exercise of skill and judgment, and even a well-conceived
transaction may be unsuccessful to some degree because of market behavior or
unexpected events.

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

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

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

          FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS.  A Fund may use
          --------------------------------------------------                 
interest rate, foreign currency or index futures contracts, as specified for
that Fund in the Prospectus.  An interest rate, foreign currency or index
futures contract provides for the future sale by one party and purchase by
another party of a specified quantity of a financial instrument, foreign
currency or the cash value of an index at a specified price and time.  A futures
contract on an index is an agreement pursuant to which two parties agree to take
or make delivery of an amount of cash equal to the difference between the value
of the

                                      -26-
<PAGE>
 
index at the close of the last trading day of the contract and the price at
which the index contract was originally written. Although the value of an index
might be a function of the value of certain specified securities, no physical
delivery of these securities is made. A public market exists in futures
contracts covering a number of indexes as well as financial instruments and
foreign currencies, including: the S&P 500; the S&P Midcap 400; the Nikkei 225;
the NYSE composite; U.S. Treasury bonds; U.S. Treasury notes; GNMA Certificates;
three-month U.S. Treasury bills; 90-day commercial paper; bank certificates of
deposit; Eurodollar certificates of deposit; the Australian dollar; the Canadian
dollar; the British pound; the German mark; the Japanese yen; the French franc;
the Swiss franc; the Mexican peso; and certain multinational currencies, such as
the European Currency Unit ("ECU"). It is expected that other futures contracts
will be developed and traded in the future.

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

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

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

          When a purchase or sale of a futures contract is made by a Fund,

                                      -27-
<PAGE>
 
the Fund is required to deposit with its custodian (or broker, if legally
permitted) a specified amount of liquid assets, such as cash, U.S. Government
securities or high grade debt obligations ("initial margin"). The margin
required for a futures contract is set by the exchange on which the contract is
traded and may be modified during the term of the contract. Margin requirements
on foreign exchanges may be different than U.S. exchanges. The initial margin is
in the nature of a performance bond or good faith deposit on the futures
contract which is returned to the Fund upon termination of the contract,
assuming all contractual obligations have been satisfied. Each Fund expects to
earn interest income on its initial margin deposits. A futures contract held by
a Fund is valued daily at the official settlement price of the exchange on which
it is traded. Each day the Fund pays or receives cash, called "variation
margin," equal to the daily change in value of the futures contract. This
process is known as "marking to market." Variation margin does not represent a
borrowing or loan by a Fund but is instead a settlement between the Fund and the
broker of the amount one would owe the other if the futures contract expired. In
computing daily net asset value, each Fund will mark to market its open futures
positions.

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

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

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

          LIMITATIONS ON USE OF FUTURES AND FUTURES OPTIONS.  In general,
          -------------------------------------------------

                                      -28-
<PAGE>
 
the Funds intend to enter into positions in futures contracts and related
options only for "bona fide hedging" purposes. With respect to positions in
futures and related options that do not constitute bona fide hedging positions,
a Fund will not enter into a futures contract or futures option contract if,
immediately thereafter, the aggregate initial margin deposits relating to such
positions plus premiums paid by it for open futures option positions, less the
amount by which any such options are "in-the-money," would exceed 5% of the
Fund's total net assets. A call option is "in-the-money" if the value of the
futures contract that is the subject of the option exceeds the exercise price. A
put option is "in-the-money" if the exercise price exceeds the value of the
futures contract that is the subject of the option.

          When purchasing a futures contract, a Fund will maintain with its
custodian (and mark-to-market on a daily basis) liquid assets, such as cash,
U.S. Government securities, or other highly liquid debt securities that, when
added to the amounts deposited with a futures commission merchant as margin, are
equal to the market value of the futures contract.  Alternatively, the Fund may
"cover" its position by purchasing a put option on the same futures contract
with a strike price as high or higher than the price of the contract held by the
Fund.

          When selling a futures contract, a Fund will maintain with its
custodian (and mark-to-market on a daily basis) liquid assets, such as cash,
U.S. Government securities or high grade debt obligations that are equal to the
market value of the instruments underlying the contract.  Alternatively, the
Fund may "cover" its position by owning the instruments underlying the contract
(or, in the case of an index futures contract, a portfolio with a volatility
substantially similar to that of the index on which the futures contract is
based), or by holding a call option permitting the Fund to purchase the same
futures contract at a price no higher than the price of the contract written by
the Fund (or at a higher price if the difference is maintained in liquid assets
with the Trust's custodian).

          When selling a call option on a futures contract, a Fund will maintain
with its custodian (and mark-to-market on a daily basis) liquid assets, such as
cash, U.S. Government securities, or other highly liquid debt securities that,
when added to the amounts deposited with a futures commission merchant as
margin, equal the total market value of the futures contract underlying the call
option.  Alternatively, the Fund may cover its position by entering into a long
position in the same futures contract at a price no higher than the strike price
of the call option, by owning the instruments underlying the futures contract,
or by holding a separate call option permitting the Fund to purchase the same
futures contract at a price not higher than the strike price of the call option
sold by the Fund.

                                      -29-
<PAGE>
 
          When selling a put option on a futures contract, a Fund will maintain
with its custodian (and mark-to-market on a daily basis) cash, U.S. Government
securities, or other highly liquid debt securities that equal the purchase price
of the futures contract, less any margin on deposit.  Alternatively, the Fund
may cover the position either by entering into a short position in the same
futures contract, or by owning a separate put option permitting it to sell the
same futures contract so long as the strike price of the purchased put option is
the same or higher than the strike price of the put option sold by the Fund.

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

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

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

                                      -30-
<PAGE>
 
prompt liquidation of positions and subjecting some holders of futures contracts
to substantial losses.

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

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

          SWAP AGREEMENTS.  The Funds may enter into interest rate, index and
          ---------------                                                    
currency exchange rate swap agreements for purposes of attempting to obtain a
particular desired return at a lower cost to the Fund than if the Fund had
invested directly in an instrument that yielded that desired return.  Swap
agreements are two party contracts entered into primarily by institutional
investors for periods ranging from a few weeks to more than one year.  In a
standard "swap" transaction, two parties agree to exchange the returns (or
differentials in rates of return) earned or realized on particular predetermined
investments or instruments.  The gross returns to be exchanged or "swapped"
between the parties are generally calculated with respect to a "notional
amount," i.e., the return on or increase in value of a particular dollar amount
         ----                                                                  
invested at a particular interest rate, in a particular foreign currency, or in
a "basket" of securities representing a particular index.  The "notional amount"
of the swap agreement is only a fictive basis on which to calculate the
obligations which the parties to a swap agreement have agreed to exchange.
Consequently, a Fund's current obligations (or rights) under a swap agreement
will generally be equal only to the net amount to be paid or received under the
agreement based on the relative values of the positions held by each party to
the agreement (the "net amount").  A Fund's current

                                      -31-
<PAGE>
 
obligations under a swap agreement will be accrued daily (offset against any
amounts owing to the Fund) and any accrued but unpaid net amounts owed to a swap
counterparty will be covered by the maintenance of a segregated account
consisting of cash, U.S. Government securities, or high grade debt obligations,
to avoid any potential leveraging of the Fund's portfolio. A Fund will not enter
into a swap agreement with any single party if the net amount owed or to be
received under existing contracts with that party would exceed 5% of the Fund's
assets.

          Whether a Fund's use of swap agreements will be successful in
furthering its investment objective of total return will depend on the Adviser's
ability to correctly predict whether certain types of investments are likely to
produce greater returns than other investments.  Because they are two party
contracts and because they may have terms of greater than seven days, swap
agreements may be considered to be illiquid.  Moreover, a Fund bears the risk of
loss of the amount expected to be received under a swap agreement in the event
of the default or bankruptcy of a swap agreement counterparty. The Adviser will
cause a Fund to enter into swap agreements only with counterparties that would
be eligible for consideration as repurchase agreement counterparties under the
Funds' repurchase agreement guidelines. Certain restrictions imposed on the
Funds by the Internal Revenue Code may limit the Funds' ability to use swap
agreements. The swaps market is a relatively new market and is largely
unregulated. It is possible that developments in the swaps market, including
potential government regulation, could adversely affect a Fund's ability to
terminate existing swap agreements or to realize amounts to be received under
such agreements.

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

                                      -32-
<PAGE>
 
in entering into or determining the terms of the swap agreement, including
pricing, cost or credit enhancement terms. Third, swap agreements may not be
entered into and traded on or through a multilateral transaction execution
facility.

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

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

WARRANTS TO PURCHASE SECURITIES

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

          A Fund will not invest more than 5% of its net assets, valued at the
lower of cost or market, in warrants to purchase securities.  Included within
that amount, but not to exceed 2% of the Fund's net assets, may be warrants that
are not listed on the New York or American Stock Exchanges.  Warrants acquired
in units or attached to securities will be deemed to be without value for
purposes of this restriction.

ILLIQUID SECURITIES

                                      -33-
<PAGE>
 
          The Funds may invest up to 15% of their net assets in illiquid
securities (10% in the case of the PIMCO Money Market Fund).  The term "illiquid
securities" for this purpose means securities that cannot be disposed of within
seven days in the ordinary course of business at approximately the amount at
which a Fund has valued the securities.  Illiquid securities are considered to
include, among other things, written over-the-counter options, securities or
other liquid assets being used as cover for such options, repurchase agreements
with maturities in excess of seven days, certain loan participation interests,
fixed time deposits which are not subject to prepayment or provide for
withdrawal penalties upon prepayment (other than overnight deposits), and other
securities whose disposition is restricted under the federal securities laws
(other than securities issued pursuant to Rule 144A and certain commercial
paper that PIMCO has determined to be liquid under procedures approved by the
Board of Trustees).

SOCIAL INVESTMENT POLICIES

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

                            INVESTMENT RESTRICTIONS

          Each Fund's investment objective as set forth in the Prospectus under
"Investment Objectives and Policies," together with the investment restrictions
set forth below, are fundamental policies of the Fund and may not be changed
with respect to a Fund without the approval of a majority of the outstanding
voting shares of that Fund.  Under these restrictions, a Fund may not:

          (1) invest in a security if, as a result of such investment, more

                                      -34-
<PAGE>
 
than 25% of its total assets (taken at market value at the time of such
investment) would be invested in the securities of issuers in any particular
industry, except that this restriction does not apply (a) to securities issued
or guaranteed by the U.S. Government or its agencies or instrumentalities (or
repurchase agreements with respect thereto) and (b) with respect to the Money
Market Fund, to securities or obligations issued by U.S. banks;

          (2) with respect to 75% of its assets, invest in a security if, as a
result of such investment, more than 5% of its total assets (taken at market
value at the time of such investment) would be invested in the securities of any
one issuer, except that this restriction does not apply to securities issued or
guaranteed by the U.S. Government or its agencies or instrumentalities (This
investment restriction is not applicable to the Commercial Mortgage Securities
Fund, the Foreign Fund, the Global Fund or the International Fund.);

          (3) with respect to 75% of its assets, invest in a security if, as a
result of such investment, it would hold more than 10% (taken at the time of
such investment) of the outstanding voting securities of any one issuer (This
restriction is not applicable to the Commercial Mortgage Securities Fund, the
Foreign Fund, the Global Fund or the International Fund);

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

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

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

          (7) borrow money, issue senior securities, or pledge, mortgage or
hypothecate its assets, except that a Fund may (i) borrow from banks or enter
into reverse repurchase agreements, or employ similar investment techniques, and
pledge its assets in connection therewith, but only if immediately after each
borrowing there is asset coverage of 300% and

                                      -35-
<PAGE>
 
(ii) enter into transactions in options, futures and options on futures and
other derivative instruments as described in the Prospectus and in this
Statement of Additional Information (the deposit of assets in escrow in
connection with the writing of covered put and call options and the purchase of
securities on a when-issued or delayed delivery basis, collateral arrangements
with respect to initial or variation margin deposits for futures contracts and
commitments entered into under swap agreements or other derivative instruments,
will not be deemed to be pledges of a Fund's assets);

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

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

          (10) (a)  for the High Yield, Total Return III, and StocksPLUS Funds:
maintain a short position, or purchase, write or sell puts, calls, straddles,
spreads or combinations thereof, except as set forth in [the] Prospectus and in
[this] Statement of Additional Information for transactions in options, futures,
and options on futures and transactions arising under swap agreements or other
derivative instruments;

               (b) for the Money Market, Short-Term, Low Duration, Low Duration
II, Low Duration III, Moderate Duration, Total Return, Total Return II,
Commercial Mortgage Securities, Long-Term U.S. Government, Foreign, Global,
International, Growth Stock and VersaSTYLE Equity Funds: maintain a short
position, or purchase, write or sell puts, calls, straddles, spreads or
combinations thereof, except on such conditions as may be set forth in the
Prospectus and in this Statement of Additional Information.

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

          (A) invest for the purpose of exercising control or management;

                                      -36-
<PAGE>
 
          (B) purchase securities of other investment companies, except that a
Fund may, for temporary purposes, purchase shares of money market mutual funds,
subject to such restrictions as may be imposed by the Investment Company Act of
1940 and rules thereunder, or by any State in which shares of the Fund are
registered (collateral arrangements with respect to securities on loan from a
Fund are not considered to involve the purchase of securities by the Fund and
are not subject to this restriction);

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

          (D) invest in a security if, as a result of such investment, more than
5% of its total assets (taken at market value at the time of such investment)
would be invested in securities of issuers (other than issuers of Federal agency
obligations) having a record, together with predecessors or unconditional
guarantors, of less than three years of continuous operation;

          (E) purchase or retain securities of any issuer if 5% of the
securities of such issuer are owned by those officers and directors or trustees
of the Trust or of the Adviser who each own beneficially more than one-half of
1% of its securities;

          (F) purchase securities for the Fund from, or sell portfolio
securities to, any of the officers and directors or trustees of the Trust or of
the Adviser;

          (G)  for the PIMCO Money Market, Short-Term, Low Duration, Low
Duration II, Low Duration III, Moderate Duration, Total Return, Total Return II,
Commercial Mortgage Securities, Long-Term U.S. Government,  Foreign, Global,
Growth Stock and VersaSTYLE Equity Funds: purchase securities on margin, except
for use of short-term credit necessary for clearance of purchases and sales of
portfolio securities, but it may make margin deposits in connection with covered
transactions in options, futures, options on futures and short positions;

                                      -37-
<PAGE>
 
          (H) (effective December 31, 1995) invest more than 5% of the assets of
a Fund (taken at market value at the time of investment) in any combination of
interest only, principal only, or inverse floating rate securities;

          (I) borrow money (excluding dollar rolls and reverse repurchase
agreements, which are subject to the Funds' fundamental borrowing restriction),
except for temporary administrative purposes, in an amount up to 5% of its total
assets; or

          (J) (a) for the PIMCO Short-Term, Low Duration and Low Duration III
Funds, invest greater than 5% of its assets in the securities of issuers based
in Newly Industrialized Countries ("NICs"); and

              (b) for the remaining Fixed Income Funds, invest greater than 10%
of its assets in the securities of issuers based in NICs.

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

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

                                      -38-
<PAGE>
 
change or modification by the SEC staff of its position.

          Unless otherwise indicated, all percentage limitations listed above
apply to each Fund only at the time a transaction is entered into.  Accordingly,
if a percentage restriction is adhered to at the time of investment, a later
increase or decrease in the percentage which results from a relative change in
values or from a change in a Fund's net assets will not be considered a
violation.

          The Trust has undertaken with a state securities commission that it
will interpret the provisions of investment restriction (5) to prohibit the
Trust's investment in oil, gas or other mineral leases and that it will
interpret the provisions of investment restriction (4) to prohibit the Trust's
investment in real estate limited partnerships.

          As an operating policy, the Trust has agreed with a state securities
commission that the dollar amount of short sales (other than short sales against
the box) at any time shall not exceed 25%  of the net equity of a Fund, and the
value of securities of any one issuer in which a Fund is short shall not exceed
2% of the Fund's net assets or 2% of the securities of any class of any issuer.

          The Trust has undertaken to a state securities commission that the
aggregate premiums paid on all options held at any time by the Trust will be
limited to 20% of the Trust's total net asset value, and that the Trust will
engage in writing options on securities only if such options are issued by the
Options Clearing Corporation or are written by the Trust with primary U.S.
Government securities dealers recognized by the Federal Reserve Bank of New
York.  Furthermore, pursuant to a restriction imposed by a state securities
commission, the Adviser waives its fee on all Trust assets invested temporarily
in shares of money market mutual funds pursuant to restriction "B", above.

INVESTMENT ADVISER

     PIMCO serves as investment adviser to the Funds pursuant to an Investment
Advisory Contract ("Advisory Contract") between PIMCO and the Trust.  PIMCO is a
subsidiary partnership of PIMCO Advisors. A majority interest of PIMCO Advisors
is held by PIMCO Partners, G.P., a general partnership between Pacific
Investment Management Company, a California corporation and indirect wholly
owned subsidiary of Pacific Mutual, and PIMCO Partners, LLC ("PIMCO Partners"),
a limited liability company controlled by the PIMCO Managing Directors.  William
H. Gross, a Managing Director of PIMCO, holds approximately 41.9% of the
ownership interests in PIMCO Partners (representing an indirect economic
interest in approximately 15.6% of the partnership units of PIMCO Advisors owned
by PIMCO Partners, G.P., or approximately 12.5% of the outstanding partnership
units of PIMCO Advisors).

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

     Under the terms of the Advisory Contract, PIMCO is obligated to manage the
Funds in accordance with applicable laws and regulations.  The investment
advisory services of PIMCO to the Trust are not exclusive under the terms of the
Advisory Contract.  PIMCO is free to, and does, render investment advisory
services to others.  The current Advisory Contract was approved by the Board of
Trustees, including a majority of the Trustees who are not parties to the
Advisory Contract or interested persons of such parties ("Independent
Trustees"), at a meeting held on May 31, 1994, as supplemented at a meeting held
on May 23, 1995 and was last approved by shareholders of all then-operational
Funds on October 17, 1994.

     The Advisory Contract will continue in effect on a yearly basis provided
such continuance is approved annually (i) by the

                                      -44-
<PAGE>
 
holders of a majority of the outstanding voting securities of the Trust or by
the Board of Trustees and (ii) by a majority of the Independent Trustees. The
Advisory Contract may be terminated without penalty by vote of the Trustees or
the shareholders of the Trust, or by the Adviser, on 60 days' written notice by
either party to the contract and will terminate automatically if assigned.

     The current Advisory Contract was executed in connection with the
consolidation of PIMCO, Pacific Investment Administrative Services Company
("PIASCo"), Thomson Advisory Group L.P. and certain other affiliated entities
(the "Consolidation").  Prior to the Consolidation, and since the inception of
each of the Funds, PIMCO had served as investment adviser to the Funds, pursuant
to an advisory contract, last approved by the Trustees April 14, 1993, and by
shareholders of the then-operational Funds on August 21, 1992 (the "Prior
Advisory Contract").  The terms and conditions of the Advisory Contract are
identical in all material respects to the Prior Advisory Contract, with the
exception of the identity of the service provider, its effective date and
termination date, and the amendment recently effected in connection with the
adoption of a new service and fee arrangement for the Funds.

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

 FUND ADMINISTRATOR

          PIMCO also serves as Administrator to the Funds pursuant to an
Administration Agreement.  PIMCO provides the Funds with certain administrative
and shareholder services necessary for Fund operations and is responsible for
the supervision of other Fund service providers.  The administrative services
provided by PIMCO include: (1) shareholder servicing functions, including
preparation of shareholder reports and communications, (2) regulatory
compliance, such as reports and filings with the SEC and state securities
commissions, and (3) general supervision of the operations of the Funds,
including coordination of the services performed by the Funds' transfer agent,
custodian, legal counsel, independent accountants, and others.  PIMCO (or an
affiliate of PIMCO) also furnishes the Funds with office space, facilities
required for conducting the business of the Funds, and pays the compensation of
those officers, employees and Trustees of the Trust affiliated with PIMCO.  In
addition, PIMCO, at its own expense, arranges for the provision of legal, audit,
custody, transfer agency and other services for the Funds, and is responsible
for the costs of registration of the Trust's shares and the printing of
prospectuses and shareholder reports for current shareholders. PIMCO has
contractually agreed to provide these services, and to bear these expenses, at
the following rates (each expressed as a percentage of the Fund's average daily
net assets on an annual basis):

</TABLE> 

          Except for the expenses paid by PIMCO, the Trust bears all costs of
its operations. The Funds are responsible for (i) salaries and other
compensation of any of the Trust's executive officers and employees who are not
officers, directors, stockholders, or employees of PIMCO or its subsidiaries or
affiliates; (ii) taxes and governmental fees; (iii) brokerage fees and
commissions and other portfolio transaction expenses; (iv) costs of borrowing
money, including interest expenses; (v) fees and expenses of the Trustees who
are not "interested persons" of PIMCO or the Trust, and any counsel retained
exclusively for their

                                      -47-
<PAGE>

benefit; (vi) extraordinary expenses, including costs of litigation and
indemnification expenses; (vii) expenses, such as organizational expenses, which
are capitalized in accordance with generally accepted accounting principles; and
(viii) any expenses allocated or allocable to a specific class of shares 
("Class-specific expenses").

          Class-specific expenses include service fees payable with respect to
the Administrative Class shares and may include certain other expenses as
permitted by the Trust's Dual Class Plan adopted pursuant to Rule 18f-3 under
the 1940 Act and subject to review and approval by the Trustees.  It is not
presently anticipated that any expenses other than service fees will be
allocated on a class-specific basis.

          The Administration Agreement for the Funds may be terminated by the
Trustees at any time on 60 days' written notice.  Following the expiration of
the two-year period commencing with the effectiveness of the agreement, it may
be terminated by PIMCO, also on 60 days' written notice.  Following its initial
two-year term, the agreement would continue from year to year if approved by the
Trustees.

          The Administration Agreement is subject to annual approval by the
Board, including a majority of the Trust's Independent Trustees (as that term is
defined in the 1940 Act).  The current Administration Agreement was approved by
the Board of Trustees, including all of the Independent Trustees at a meeting
held on August 22, 1995.  In approving the Administration Agreement, the
Trustees determined that:  (1) the Administration Agreement is in the best
interests of the Funds and their shareholders; (2) the services to be performed
under the Agreement are services required for the operation of the Funds; (3)
the Administrator is able to provide, or to procure, services for the Funds
which are at least equal in nature and quality to services that could be
provided by others; and (4) the fees to be charged pursuant to the Agreement are
fair and reasonable in light of the usual and customary charges made by others
for services of the same nature and quality.  The preceding Administrative
Services Contract between the Trust and PIMCO was approved by the Trustees at
their meeting held on May 31, 1994, and was approved by shareholders of all
then-operational Funds on October 17, 1994.

          A previous Administrative Services Contract ("Prior Contact") between
the Trust and PIASCo was initially approved by the Trustees at their meeting
held on April 29, 1987 (and by the then-sole shareholder of the Trust at a
meeting held on April 30, 1987).  The Prior Contract was last approved by the
Board of Trustees on February 23, 1993.  PIASCo was a wholly owned

                                      -48-
<PAGE>
 
subsidiary of the predecessor of PIMCO. In connection with the Consolidation,
PIMCO assumed the duties of PIASCo as Administrator to the Funds. The terms and
conditions of the Administrative Services Contract are identical in all material
respects to those of the Prior Contract, with the exception of the identity of
the service provider, its effective date and termination date, and the amendment
recently effected in connection with the adoption of a new service and fee
arrangement for the Funds.

          For the fiscal years ended March 31, 1995, 1994, and 1993, the
aggregate amount of the administration fee paid by each operational Fund was as
follows:

EXPENSE LIMITATIONS

     Certain of the states in which the shares of the Trust are qualified for
sale impose limitations on the expenses of the Trust.  If, in any fiscal year,
the total expenses of the Trust (excluding taxes, interest, brokerage
commissions and other portfolio transaction expenses, other expenditures which
are capitalized in accordance with generally accepted accounting principles and
extraordinary expenses, but including the advisory and administrative fees)
exceed the expense limitations applicable to the Trust imposed by the securities
regulations of any state, PIMCO will reimburse the Trust for the excess.

     Fees foregone or payments made by PIMCO with respect to a Fund pursuant to
the expense limitation are contingent liabilities of the Fund which are subject
to potential reimbursement by that Fund to PIMCO, provided the assets of the
Fund reach a sufficient size to permit such reimbursement to be made without
causing the covered expenses of the Fund to exceed the amount as may be imposed
by any state expense limit to which the Trust is subject, and provided such
reimbursement is made within four years of the recognition of the contingent
liability by the Fund.  If a reimbursement appears probable, it will be
accounted for as an expense of the Fund regardless of the time period over which
the reimbursement may actually be paid by the Fund.

DISTRIBUTION OF TRUST SHARES

          Each Fund offers two classes of shares: the "Institutional Class" and
the "Administrative Class." Shares of the

                                      -50-
<PAGE>
 
Institutional Class are offered primarily for direct investment by institutional
investors and high net worth individuals. They also are offered through certain
financial intermediaries that charge their customers transaction or other fees
with respect to the customer's investment in the Funds. Shares of the
Administrative Class are offered primarily through brokers, retirement plan
administrators and other financial intermediaries. Administrative Class shares
pay service fees to such entities for services they provide to shareholders of
that class.

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

          PIMCO Advisors Distribution Company ("PADCO" or the "Distributor")
serves as the Trust's Distributor pursuant to a Distribution Contract
("Distribution Contract") dated November 22, 1994, which is subject to annual
approval by the Board. The Distributor is a wholly owned subsidiary of PIMCO
Advisors. The Distribution Contract is terminable with respect to a Fund without
penalty, at any time, by the Trust upon 60 days' written notice to the
Distributor or by the Distributor upon 60 days' notice, to the Trust. The
Distributor is not obligated to sell any specific amount of Trust shares.

          Prior to the Consolidation, Pacific Equities Network ("PEN"), an
indirect subsidiary of Pacific Mutual, served as the Trust's Distributor,
pursuant to a contract approved by the Board of Trustees, including a majority
of the Independent Trustees, at its meeting held on April 29, 1987 (and by the
then-sole shareholder of the Trust at a meeting held on April 30, 1987) (the
"Prior Distribution Contract"). The Prior Distribution Contract was approved
with respect to the PIMCO International Fund by the Board of Trustees (including
a majority of the Independent Trustees) at a meeting held on August 22, 1989,
and by the then-sole shareholder of the Fund at a meeting held on September 29,
1989. The Prior Distribution Contract was last approved by the Board of Trustees
on February 23, 1993 and by shareholders of the Trust on November 1, 1988. The
Prior Distribution Contract was approved

                                      -51-
<PAGE>
 
with respect to the PIMCO Low Duration III, Total Return III, Foreign, and
Global Funds by the Trustees (including a majority of the Independent Trustees)
on August 28, 1990, and by the then-sole shareholder of such Funds on September
28, 1990. The Prior Distribution Contract was approved with respect to the PIMCO
Low Duration II, Total Return II, and High Yield Funds by the Board of Trustees
on May 28, 1991, and by the then-sole shareholder of these Funds on July 15,
1991.

SERVICE FEES

     The Trust has adopted an Administrative Services Plan and a Distribution
Plan with respect to the Administrative Class shares of each Fund.  Under the
terms of each Plan, the Trust is permitted to reimburse, out of the
Administrative Class assets of each Fund, in an amount up to 0.25% on an annual
basis of the average daily net assets of that class, financial intermediaries
that provide services in connection with the distribution of shares or
administration of plans or programs that use Fund shares as their funding
medium, and to reimburse certain other distribution related expenses.  Under the
terms of the Distribution Plan, these services may include, but are not limited
to, the following functions:  providing facilities to answer questions from
prospective investors about the Fund; receiving and answering correspondence,
including requests for prospectuses and statements of additional information;
preparing, printing and delivering prospectuses and shareholder reports to
prospective shareholders; complying with federal and state securities laws
pertaining to the sale of Administrative Class shares; and assisting investors
in completing application forms and selecting dividend and other account
options.

     Under the terms of the Administrative Services Plan, the services may
include, but are not limited to, the following functions:  receiving,
aggregating and processing shareholder orders; furnishing shareholder sub-
accounting; providing and maintaining elective shareholder services such as
check writing and wire transfer services; providing and maintaining pre-
authorized investment plans; communicating periodically with shareholders;
acting as the sole shareholder of record and nominee for shareholders;
maintaining accounting records for shareholders; answering questions and
handling correspondence from shareholders about their accounts; and performing
similar account administrative services.

     The same entity may be the recipient of fees under both the Distribution
Plan and the Administrative Services Plan, but may not receive fees under both
plans with respect to the same assets.

                                      -52-
<PAGE>
 
     Each Plan provides that it may not be amended to materially increase the
costs which Administrative Class shareholders may bear under the Plan without
the approval of a majority of the outstanding voting securities of the class,
and by vote of a majority of both (i) the Trustees of the Trust and (ii) those
Trustees who are not "interested persons" of the Trust (as defined in the 1940
Act) and who have no direct or indirect financial interest in the operation of
the Plan or any agreements related to it (the "Plan Trustees"), cast in person
at a meeting called for the purpose of voting on the Plan and any related
amendments.

     Each Plan provides that it may not take effect until approved by vote of a
majority of both (i) the Trustees of the Trust and (ii) the Plan Trustees.  The
Distribution Plan further provides that it may not take effect unless approved
by the vote of a majority of the outstanding voting securities of the class.
The Plans were approved by the Trustees, including the Plan Trustees, at a
meeting held May 31, 1994.

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

     Each Plan provides that expenses payable under the Plan may be carried
forward for reimbursement for up to twelve months beyond the date in which the
expense is incurred, subject to the limit that not more that 0.25% of the
average daily net assets of each class may be used in any month to pay expenses
under the Plan.  Each Plan requires that Administrative Class shares will incur
no interest or carrying charges.

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

                                      -53-
<PAGE>
 
     For the fiscal year ended March 31, 1995, the Administrative Class shares
of the PIMCO Low Duration, High Yield, and Total Return Funds paid aggregate
fees under the Distribution Plan to qualified service providers in the amount of
$445.29, $20.45, and $5,325.11, respectively.  All of these amounts constituted
"service fees" under applicable NASD rules.

THE REORGANIZATION

     The offer and sale of shares of the PIMCO Money Market Fund and PIMCO Total
Return Fund II is contingent upon the consummation of a reorganization of these
Funds as series of the Trust (the "Reorganization").  The Trust has entered into
an Agreement and Plan of Reorganization with PIMCO Advisors Institutional Funds
("PAIF"), another registered open-end investment company, pursuant to which the
PIMCO Managed Bond and Income Fund and Money Market Fund would transfer their
respective assets to two currently non-operational series of the Trust, the
Income and Capital Preservation Fund and the Income and Capital Preservation
Fund II, in exchange for shares of those Funds, to be renamed PIMCO Total Return
Fund II and PIMCO Money Market Fund.  A non-operational series of the Trust
formerly known as the PIMCO Total Return Fund II will be liquidated prior to the
Reorganization.

     Prior to the closing of the Reorganization, which is anticipated to take
place November 1, 1995, the sole shareholder of the Income and Capital
Preservation Fund and the Income and Capital Preservation Fund II will change
the names and certain investment policies of the Funds to conform with the PIMCO
Managed Bond and Income Fund and Money Market Fund.  Consummation of the
Reorganization is contingent upon several conditions, including receipt of: 1)
approval of the shareholders of the Funds; 2) a finding by the Trustees of PAIF
and the Trust that the Reorganization is in the best interests of shareholders;
3) an opinion of counsel that the Reorganization will qualify for Federal income
tax purposes as a tax-free reorganization; and 4) any necessary regulatory
approvals.

PURCHASES AND REDEMPTIONS

     Purchases and redemptions are discussed in the Prospectus under the
headings "Purchase of Shares," "Redemption of Shares," and "Net Asset Value,"
and that information is incorporated herein by reference.

     Certain managed account clients of the Adviser may purchase shares of the
Trust.  To avoid the imposition of duplicative fees, the Adviser may be required
to make adjustments in the management

                                      -54-
<PAGE>
 
fees charged separately by the Adviser to these clients to offset the generally
higher level of management fees and expenses resulting from a client's
investment in the Trust.

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

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

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

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

     Due to the relatively high cost of maintaining smaller accounts, the Trust
reserves the right to redeem shares in any account for their then-current value
(which will be promptly paid to the investor) if at any time, due to shareholder
redemption, the shares in the account do not have a value of at least $10,000
($100,000 with respect to accounts opened after January 1, 1995).  An investor
will be notified that the value of his account is less than the minimum and
allowed at least 30 days to bring the value of the account up to at least
$10,000 (or $100,000, as

                                      -55-

applicable) before the redemption is processed. The Declaration of Trust also
authorizes the Trust to redeem shares under certain other circumstances as may
be specified by the Board of Trustees.


                      PORTFOLIO TRANSACTIONS AND BROKERAGE

INVESTMENT DECISIONS

     Investment decisions for the Trust and for the other investment advisory
clients of the Adviser are made with a view to achieving their respective
investment objectives. Investment decisions are the product of many factors in
addition to basic suitability for the particular client involved (including the
Trust). Thus, a particular security may be bought or sold for certain clients
even though it could have been bought or sold for other clients at the same
time. Likewise, a particular security may be bought for one or more clients when
one or more clients are selling the security. In some instances, one client may
sell a particular security to another client. It also sometimes happens that two
or more clients simultaneously purchase or sell the same security, in which
event each day's transactions in such security are, insofar as possible,
averaged as to price and allocated between such clients in a manner which in the
Adviser's opinion is equitable to each and in accordance with the amount being
purchased or sold by each. There may be circumstances when purchases or sales of
portfolio securities for one or more clients will have an adverse effect on
other clients.

BROKERAGE AND RESEARCH SERVICES

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

     The Adviser places all orders for the purchase and sale of portfolio
securities, options and futures contracts for the Trust and buys and sells such
securities, options and futures for the

                                      -56-
<PAGE>
 
Trust through a substantial number of brokers and dealers. In so doing, the
Adviser uses its best efforts to obtain for the Trust the most favorable price
and execution available, except to the extent it may be permitted to pay higher
brokerage commissions as described below. In seeking the most favorable price
and execution, the Adviser, having in mind the Trust's best interests, considers
all factors it deems relevant, including, by way of illustration, price, the
size of the transaction, the nature of the market for the security, the amount
of the commission, the timing of the transaction taking into account market
prices and trends, the reputation, experience and financial stability of the
broker-dealer involved and the quality of service rendered by the broker-dealer
in other transactions. For the fiscal years ended March 31, 1995, 1994, and
1993, the PIMCO Growth Stock Fund paid brokerage commissions in the aggregate
amounts of $52,379, $47,720, and $38,295, respectively. The PIMCO VersaSTYLE
Equity Fund paid brokerage commissions in the aggregate amount of $23,037, for
the fiscal year ended March 31, 1995. None of these amounts were paid to an
affiliate of the Trust, the Adviser, PADCO or PEN.

     The Adviser manages the Funds without regard generally to restrictions on
portfolio turnover, except those imposed on its ability to engage in short-term
trading by provisions of the federal tax laws (see "Taxation").  The use of
futures contracts and other derivative instruments with relatively short
maturities may tend to exaggerate the portfolio turnover rate for some of the
Funds.  Trading in fixed-income securities does not generally involve the
payment of brokerage commissions, but does involve indirect transaction costs.
The use of futures contracts may involve the payment of commissions to futures
commission merchants.  The higher the rate of portfolio turnover of a Fund, the
higher these transaction costs borne by the Fund generally will be.

     The portfolio turnover rate of a Fund is calculated by dividing (a) the
lesser of purchases or sales of portfolio securities for the particular fiscal
year by (b) the monthly average of the value of the portfolio securities owned
by the Fund during the particular fiscal year.  In calculating the rate of
portfolio turnover, there is excluded from both (a) and (b) all securities,
including options, whose maturities or expiration dates at the time of
acquisition were one year or less.   Proceeds from short sales and assets used
to cover short positions undertaken are included in the amounts of securities
sold and purchased, respectively, during the year.

     It has for many years been a common practice in the investment advisory
business for advisers of investment companies and

                                      -57-
<PAGE>
 
other institutional investors to receive research services from broker-dealers
which execute portfolio transactions for the clients of such advisers.
Consistent with this practice, the Adviser receives research services from many
broker-dealers with which the Adviser places the Trust's portfolio transactions.
These services, which in some cases may also be purchased for cash, include such
matters as general economic and security market reviews, industry and company
reviews, evaluations of securities and recommendations as to the purchase and
sale of securities. Some of these services are of value to the Adviser in
advising various of its clients (including the Trust), although not all of these
services are necessarily useful and of value in managing the Trust. The
management fee paid by the Trust is not reduced because the Adviser and its
affiliates receive such services.

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

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

                                NET ASSET VALUE

     As indicated under "Net Asset Value" in the Prospectus, the Trust's net
asset value per share for the purpose of pricing purchase and redemption orders
is determined at 4:00 p.m. (Eastern time) on each day the New York Stock
Exchange is open for trading.  Net asset value will not be determined on the
following holidays:  New Year's Day, President's Day, Good Friday, Memorial Day,
Independence Day, Labor Day, Thanksgiving Day, and Christmas Day.

     The PIMCO Money Market Fund's securities are valued using the amortized
cost method of valuation.  This involves valuing a security at cost on the date
of acquisition and thereafter assuming a constant accretion of a discount or
amortization of a premium to maturity, regardless of the impact of fluctuating
interest rates on the market value of the instrument.  While this method
provides certainty in valuation, it may result in periods during which value, as
determined by amortized cost, is higher or lower than the price the Fund would
receive if it sold the

                                      -58-
<PAGE>
 
instrument. During such periods the yield to investors in the Fund may differ
somewhat from that obtained in a similar investment company which uses available
market quotations to value all of its portfolio securities.

     The Securities and Exchange Commission's regulations require the PIMCO
Money Market Fund to adhere to certain conditions.  The Trustees, as part of
their responsibility within the overall duty of care owed to the shareholders,
are required to establish procedures reasonably designed, taking into account
current market conditions and the Fund's investment objective, to stabilize the
net asset value per share as computed for the purpose of distribution and
redemption at $1.00 per share.  The Trustees' procedures include a requirement
to periodically monitor, as appropriate and at such intervals as are reasonable
in light of current market conditions, the relationship between the amortized
cost value per share and the net asset value per share based upon available
indications of market value.  The Trustees will consider what steps should be
taken, if any, in the event of a difference of more than 1/2 of 1% between the
two.  The Trustees will take such steps as they consider appropriate, (e.g.,
selling securities to shorten the average portfolio maturity) to minimize any
material dilution or other unfair results which might arise from differences
between the two.  The Fund also is required to maintain a dollar-weighted
average portfolio maturity of 90 days or less, to limit its investments to
instruments having remaining maturities of 13 months or less (except securities
held subject to repurchase agreements having 13 months or less maturity) and to
invest only in securities determined by the Adviser under procedures established
by the Board of Trustees to be of high quality with minimal credit risks.
 
                                    TAXATION

     While the Adviser anticipates that many shareholders of the Trust will be
tax-exempt institutions, the following discussion may be of general interest to
these shareholders as well as for those shareholders of the Trust who do not
have tax-exempt status.  The following discussion is general in nature and
should not be regarded as an exhaustive presentation of all possible tax
ramifications.  All shareholders should consult a qualified tax adviser
regarding their investment in a Fund.

     Each Fund intends to qualify annually and elect to be treated as a
regulated investment company under the Internal Revenue Code of 1986, as amended
(the "Code").  To qualify as a regulated investment company, each Fund generally
must, among other things, (a) derive in each taxable year at least 90% of its
gross income from dividends, interest, payments with respect to securities

                                      -59-
<PAGE>
 
loans, and gains from the sale or other disposition of stock, securities or
foreign currencies, or other income derived with respect to its business of
investing in such stock, securities or currencies ("Qualifying Income Test");
(b) derive in each taxable year less than 30% of its gross income from the sale
or other disposition of certain assets held less than three months, namely (1)
stocks or securities, (2) options, futures, or forward contracts (other than
those on foreign currencies), and (3) foreign currencies (or options, futures,
and forward contracts on foreign currencies) not directly related to the Fund's
principal business of investing in stock or securities; (c) diversify its
holdings so that, at the end of each quarter of the taxable year, (i) at least
50% of the market value of the Fund's assets is represented by cash, U.S.
Government securities, the securities of other regulated investment companies
and other securities, with such other securities of any one issuer limited for
the purposes of this calculation to an amount not greater than 5% of the value
of the Fund's total assets and 10% of the outstanding voting securities of such
issuer, and (ii) not more than 25% of the value of its total assets is invested
in the securities of any one issuer (other than U.S. Government securities or
the securities of other regulated investment companies); and (d) distribute at
least 90% of its investment company taxable income (which includes dividends,
interest and net short-term capital gains in excess of any net long-term capital
losses) each taxable year. The Treasury Department is authorized to promulgate
regulations under which gains from foreign currencies (and options, futures, and
forward contracts on foreign currency) would constitute qualifying income for
purposes of the Qualifying Income Test only if such gains are directly relating
to investing in securities. To date, such regulations have not been issued.

     As a regulated investment company, a Fund generally will not be subject to
U.S. federal income tax on its investment company taxable income and net capital
gains (any net long-term capital gains in excess of the sum of net short-term
capital losses and capital loss carryovers from prior years) designated by the
Fund as capital gain dividends, if any, that it distributes to shareholders on a
timely basis.  Each Fund intends to distribute to its shareholders, at least
annually, substantially all of its investment company taxable income and any net
capital gains.  In addition, amounts not distributed by a Fund on a timely basis
in accordance with a calendar year distribution requirement are subject to a
nondeductible 4% excise tax.  To avoid the tax, a Fund must distribute during
each calendar year an amount equal to the sum of (1) at least 98% of its
ordinary income (not taking into account any capital gains or losses) for the
calendar year, (2) at least 98% of its capital gains in excess of its capital
losses (and adjusted for certain ordinary losses) for the twelve

                                      -60-
<PAGE>
 
month period ending on October 31 of the calendar year, and (3) all ordinary
income and capital gains for previous years that were not distributed during
such years. A distribution will be treated as paid on December 31 of the
calendar year if it is declared by a Fund in October, November, or December of
that year to shareholders of record on a date in such a month and paid by the
Fund during January of the following year. Such distributions will be taxable to
shareholders (other than those not subject to federal income tax) in the
calendar year in which the distributions are declared, rather than the calendar
year in which the distributions are received. To avoid application of the excise
tax, each Fund intends to make its distributions in accordance with the calendar
year distribution requirement.

DISTRIBUTIONS

     Dividends paid out of a Fund's investment company taxable income will be
taxable to a U.S. shareholder as ordinary income.  Distributions received by
tax-exempt shareholders will not be subject to federal income tax to the extent
permitted under the applicable tax exemption.

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

                                      -61-
<PAGE>
 
SALES OF SHARES

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

BACKUP WITHHOLDING

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

OPTIONS, FUTURES AND FORWARD CONTRACTS, AND SWAP AGREEMENTS

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

                                      -62-
<PAGE>

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

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

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

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

     The 30% limit on gains from the disposition of certain options, futures,
forward contracts, and swap agreements held less than three months and the
qualifying income and diversification

                                      -63-
<PAGE>
 
requirements applicable to a Fund's assets may limit the extent to which a Fund
will be able to engage in transactions in options, futures contracts, forward
contracts, and swap agreements.

SHORT SALES

     Certain Funds may make short sales of securities.  Short sales may increase
the amount of short-term capital gain realized by a Fund, which is taxed as
ordinary income when distributed to shareholders.  Moreover, the 30% limit on
gains from the disposition of securities held less than three months may limit
the extent to which a Fund will be able to engage in short sales.

PASSIVE FOREIGN INVESTMENT COMPANIES

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

     A Fund may be eligible to elect alternative tax treatment with respect to
PFIC stock.  Under an election that currently is available in some
circumstances, a Fund generally would be required to include in its gross income
its share of the earnings of a PFIC on a current basis, regardless of whether
distributions are received from the PFIC in a given year.  If this election were
made, the special rules, discussed above, relating to the taxation of excess
distributions, would not apply.  In addition, another election may be available
that would involve marking to market a Fund's PFIC shares at the end of each
taxable year (and on certain other dates prescribed in the Code), with the
result that unrealized gains are treated as though they were realized.  If

                                      -64-
<PAGE>
 
this election were made, tax at the Fund level under the PFIC rules would
generally be eliminated, but the Fund could, in limited circumstances, incur
nondeductible interest charges. A Fund's intention to qualify annually as a
regulated investment company may limit its elections with respect to PFIC
shares.

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

FOREIGN CURRENCY TRANSACTIONS

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

                                      -65-
<PAGE>
 
FOREIGN TAXATION

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

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

                                      -66-
<PAGE>
 
ORIGINAL ISSUE DISCOUNT

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

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

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

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

OTHER TAXATION

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

CAPITALIZATION

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

     Expenses incurred by the Trust in connection with its organization and the
public offering of its shares aggregated approximately $75,971.  These costs
have been deferred and amortized on a straight line basis over a period not less
than

                                      -68-

five years. Expenses incurred in the organization of subsequently offered Funds
are charged to those Funds and are being amortized on a straight line basis over
a period not less than five years.

PERFORMANCE INFORMATION

     The Trust may, from time to time, include the yield and effective yield of
the PIMCO Money Market Fund, and the yield and total return for each class of
shares of all of the Funds, computed in accordance with SEC-prescribed formulas,
in advertisements or reports to shareholders or prospective investors.  The
Funds also may compute current distribution rates and use this information in
their prospectuses and statement of additional information, in reports to
current shareholders, or in certain types of sales literature provided to
prospective investors.

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

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

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

                                      -69-
<PAGE>
 
        YIELD = 2[( a-b + 1)/6/-1]
                    ---           
                    cd

where   a =  dividends and interest earned during the period,

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

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

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

     Quotations of average annual total return for a Fund or class will be
expressed in terms of the average annual compounded rate of return of a
hypothetical investment in the Fund or class over periods of one, five and ten
years (up to the life of the Fund), calculated pursuant to the following
formula:  P (1 + T)/n/ = ERV (where P = a hypothetical initial payment of
$1,000, T = the average annual total return, n = the number of years, and ERV =
the ending redeemable value of a hypothetical $1,000 payment made at the
beginning of the period).  All total return figures reflect the deduction of a
proportional share of Fund or class expenses on an annual basis, and assume that
all dividends and distributions are reinvested when paid.  The Funds also may,
with respect to certain periods of less than one year, provide total return
information for that period that is unannualized.  Any such information would be
accomplished by standardized total return information.

     For the one month period ended March 31, 1995, the yield of the Funds
(Institutional Class unless otherwise noted) was as follows (all numbers are
annualized):

     *The total return of the PIMCO Money Market Fund for the one-year period
ended October 31, 1994, was 3.53% and was 3.82% since inception (March 1, 1991).
The total return of the PIMCO Money Market Fund for the six month period ended
April 30, 1995, was 2.73% for the Institutional Class and was 1.44% for the
Administrative Class.  The total return of the PIMCO Total Return Fund II for
the one year period ended October 31, 1994, was (3.58%) and was 5.99% since
inception (December 30, 1991).  The total return of the PIMCO Total Return Fund
II for the six month period ended April 30, 1995, was 7.01% for the
Institutional Class and 7.11% for the Administrative Class; and was 7.25%
(annualized) since inception, for the Institutional Class, and was 18.32%
(annualized) since inception, for the Administrative Class.  See "The
Reorganization" for additional information.

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

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

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

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

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

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

     For the month ended March 31, 1995, the current distribution rates

VOTING RIGHTS

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

     The Trust's shares do not have cumulative voting rights, so that the holder
of more than 50% of the outstanding shares may elect the entire Board of
Trustees, in which case the holders of the remaining shares would not be able to
elect any Trustees.

CODE OF ETHICS

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

     Pursuant to rules adopted under the 1940 Act, the Trust may maintain
foreign securities and cash in the custody of certain eligible foreign banks and
securities depositories.  Selection of these foreign custodial institutions is
made by the Board of Trustees following a consideration of a number of factors,
including (but not limited to) the reliability and financial stability of the
institution; the ability of the institution to perform capably custodial
services for the Trust; the reputation of the institution in its national
market; the political and economic stability of the country in which the
institution is located; and further risks of potential nationalization or
expropriation of Trust assets.  The Board of Trustees reviews annually the
continuance of foreign custodial arrangements for the Trust.  No assurance can
be given that the Trustees' appraisal of the risks in connection with foreign
custodial arrangements will always be correct or that expropriation,
nationalization, freezes, or confiscation of assets that would impact assets of
the Funds will not occur, and shareholders bear the risk of losses arising from
these or other events.

INDEPENDENT ACCOUNTANTS

     Price Waterhouse LLP, 1055 Broadway, Kansas City, MO  64105, serves as
independent accountants for all Funds.  Price Waterhouse LLP provides audit
services, tax return preparation and assistance and consultation in connection
with review of Securities and Exchange Commission filings.  It is anticipated
that Price Waterhouse LLP will serve as independent accountants for the PIMCO
Money Market Fund and PIMCO Total Return Fund II following the Reorganization
discussed above. See "The Reorganization," for additional information.
