rate prospectuses, certain Funds and other series of the Trust of-
fer up to five additional classes of shares, Institutional Class,
Administrative Class, Class A, Class B and Class C shares. See
"Description of the Trust--Multiple Classes of Shares."
This Prospectus concisely describes the information investors
should know before investing in Class D shares of the Funds.

1. The Funds' administration agreement includes a plan for Class D
shares that has been adopted in conformity with the requirements
set forth in Rule 12b-1 of the Investment Company Act of 1940. The
plan provides that up to .25% per annum of the total fees paid un-
der the administration agreement may represent reimbursement for
expenses in respect of activities ("subject activities") that may
be deemed to be primarily intended to result in the sale of Class
D shares. The Short-Term, Low Duration and Total Return Funds will
pay a total of .50% per annum, the Municipal Bond Fund will pay a
total of .60% per annum, the Foreign Bond Fund will pay a total of
.70% per annum, and each remaining Fund will pay a total of .65%
per annum, under the administration agreement regardless of
whether a portion or none of the .25% authorized under the plan is
paid for subject services. To the extent that any payments are
deemed to be made pursuant to the plan, the Funds intend to treat
such payments as "service fees" for purposes of applicable rules
of the National Association of Securities Dealers, Inc. (the
"NASD"). See "Management of the Trust--Fund Administrator." To the
extent that such payments for subject activities are deemed not to
be "service fees," Class D shareholders may, depending on the
length of time the shares are held, pay more than the economic
equivalent of the maximum front-end sales charges permitted by
relevant rules of the NASD.
The purpose of the foregoing tables is to assist investors in un-
derstanding the various costs and expenses of the Trust that are
borne directly or indirectly by Class D shareholders of the Funds.
The information is based upon each Fund's current fees and ex-
penses.
NOTE: THE FIGURES SHOWN IN THE EXAMPLE ARE ENTIRELY HYPOTHETICAL.
THEY ARE NOT REPRESENTATIONS OF PAST OR FUTURE PERFORMANCE OR EX-

Investment Objectives and Policies
The investment objective and general investment policies of each
Fund are described below. There can be no assurance that the in-
vestment objective of any Fund will be achieved. For temporary,
defensive or emergency purposes, a Fund may invest without limit
in U.S. debt securities, including short-term money market securi-
ties, when in the opinion of the Advisor it is appropriate to do
so. It is impossible to predict for how long such alternative
strategies will be utilized. The value of all securities and other
instruments held by the Funds will vary from time to time in re-
sponse to a wide variety of market factors. Consequently, the net
asset value per share of each Fund will vary.
The investment objective of each Fund is fundamental and may
not be changed without shareholder approval by vote of a majority
of the outstanding shares of that Fund. If there is a change in a
Fund's investment objective, including a change approved by a
shareholder vote, shareholders should consider whether the Fund
remains an appropriate investment in light of their then current
financial position and needs.
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 de-
scribed more fully under "Characteristics and Risks of Securities
and Investment Techniques" in this Prospectus and "Investment Ob-
jectives and Policies" in the Statement of Additional Information.
FIXED With the exception of the Strategic Balanced and StocksPLUS Funds,
INCOME FUND each remaining Fund (together, the "Fixed Income Funds") differs
DESCRIP- from the others primarily in the length of the Fund's duration or
TIONS the proportion of its investments in certain types of fixed income
securities. For a discussion of the concept of duration, see "Ap-
pendix A--Description of Duration."
The investment objective of the Short-Term Fund is to seek to
obtain maximum current income consistent with preservation of cap-
ital and daily liquidity. The investment objective of the Real Re-
turn Bond Fund is to seek to realize maximum real return, consis-
tent with the preservation of real capital and prudent investment
management. For a discussion of "real return," see "Total Return
and Real Return," below. The investment objective of the Municipal
Bond Fund is to seek high current income exempt from federal in-
come tax, consistent with preservation of capital. Capital appre-
ciation is a secondary objective of the Municipal Bond Fund. Each
of the remaining Fixed Income Funds and the Strategic Balanced
Fund seek to maximize total return, consistent with preservation
of capital and prudent investment management.
In selecting securities for each Fixed Income Fund, the Advisor
utilizes economic forecasting, interest rate anticipation, credit
and call risk analysis, foreign currency exchange rate forecast-
ing, and other security selection techniques. The proportion of
each Fund's assets committed to investment in securities with par-
ticular characteristics (such as maturity, type and coupon rate)
will vary based on the Advisor'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 specif-
ically provided otherwise in the descriptions of the Funds that
follow, may be issued by domestic or foreign entities and denomi-
nated in U.S. dollars or foreign currencies: securities issued or
guaranteed by the U.S. Government, its agencies or instrumentali-
ties ("U.S. Government securities"); corporate debt securities,
including convertible securities and corporate commercial paper;
mortgage-backed and other asset-backed securities; inflation-in-
dexed bonds issued by both governments and corporations; struc-
tured notes, including hybrid or "indexed" securities, and loan
participations; delayed funding loans and revolving credit facili-
ties; bank certificates of deposit, fixed time deposits and bank-
ers' acceptances; repurchase agreements and reverse repurchase
agreements; debt securities issued by states or local governments
and their agencies, authorities and other instrumentalities; obli-
gations 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 inter-
est that vary inversely at a multiple of a designated or floating
rate, or that vary according to changes in relative values of cur-
rencies. Each of the Fixed Income Funds may hold different per-
centages of its assets in these various types of securities, and
each Fund may invest all of its assets in derivative instruments
or in mortgage- or asset-backed securities. Each of the Fixed In-
come
April 8, 1998 Prospectus 5
<PAGE>
Funds may adhere to its investment policy by entering into a se-
ries of purchase and sale contracts or utilizing other investment
techniques by which it may obtain market exposure to the securi-
ties in which it primarily invests.
In addition, each of the Fixed Income Funds may lend its port-
folio securities to brokers, dealers and other financial institu-
tions in order to earn income. Each of the Fixed Income Funds may
purchase and sell options and futures subject to the limits dis-
cussed below, engage in credit spread trades and enter into for-
ward foreign currency contracts.
The Real Return Bond and Foreign Bond Funds will normally in-
vest at least 80% of its total assets in "bonds." For this pur-
pose, each of these Funds considers the various types of debt or
fixed income securities in which it invests, as specifically de-
scribed elsewhere in this Prospectus, to be "bonds" as referenced
in that Fund's name. The use of this name is not meant to restrict
a Fund's investment to the narrow category of debt securities that
are formally called "bonds."
As a non-fundamental, operating policy, the Advisor 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 denominated in currencies other than the U.S. dollar. There
can be no assurance that the Advisor will be successful in doing
so. The active use of currency derivatives involves transaction
costs which may adversely effect yield and return.
The compositions of the Fixed Income Funds differ as follows:
SHORT-TERM FUND invests in a diversified portfolio of fixed income
securities of varying maturities. The average portfolio duration
of this Fund will normally not exceed one year. The Fund may in-
vest up to 10% of its assets in fixed income securities that are
rated below investment grade (rated below Baa by Moody's Investors
Service, Inc. ("Moody's") or BBB by Standard & Poor's Ratings
Services ("S&P")) but rated B or higher by Moody's or S&P (or, if
unrated, determined by the Advisor to be of comparable quality).
For information on the risks associated with investments in secu-
rities rated below investment grade, see "Appendix B--Description
of Securities Ratings." The Fund may invest up to 5% of its assets
in securities denominated in foreign currencies, and may invest
beyond this limit in U.S. dollar-denominated securities of foreign
issuers.
LOW DURATION FUND invests in a diversified portfolio of fixed in-
come securities of varying maturities. The average portfolio dura-
tion of this Fund will normally vary within a one- to three-year
time frame based on the Advisor's forecast for interest rates. 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 Advisor to be of
comparable quality). For information on the risks associated with
investments in securities rated below investment grade, see "Ap-
pendix B--Description of Securities Ratings." The Fund may invest
up to 20% of its assets in securities denominated in foreign cur-
rencies, and may invest beyond this limit in U.S. dollar-denomi-
nated securities of foreign issuers.
The total rate of return for this Fund is expected to exhibit less
volatility than that of the Total Return Fund because its duration
will be shorter.
REAL RETURN BOND FUND invests under normal circumstances at least
65% of its total assets in inflation-indexed bonds issued by U.S.
and foreign governments, their agencies or instrumentalities. All
securities purchased by the Fund must be rated at least A by
Moody's or S&P (or, if unrated, determined by the Advisor to be of
comparable quality), and the Fund will maintain a minimum average
quality of Aa. The Fund may invest up to 35% of its assets in
other types of fixed income instruments, including securities de-
nominated in foreign currencies (and the Fund may also invest be-
yond this limit in U.S. dollar-denominated securities of foreign
issuers).
Inflation-indexed bonds are fixed income securities whose prin-
cipal value is periodically adjusted according to the rate of in-
flation. Such bonds generally are issued at an interest rate lower
than non-inflation related bonds, but are
6 PIMCO Funds: Pacific Investment Management Series
<PAGE>
expected to retain their value against inflation over time. For a
more complete discussion of inflation-indexed bonds, including the
risks associated with investing in such securities, see "Charac-
teristics and Risks of Securities and Investment Techniques--In-
flation-Indexed Bonds." See "Taxes" for information about the pos-
sible tax consequences of investing in the Fund and in inflation-
indexed bonds.
In managing fixed income securities, one of the principal tools
generally used by the Advisor is "duration," which is a measure of
the expected life of a fixed income security on a present value
basis, incorporating a bond's yield, coupon interest payments, fi-
nal maturity and call features. See "Appendix A--Description of
Duration." Because of the unique features of inflation-indexed
bonds, the Advisor utilizes a modified form of duration for the
Real Return Bond Fund ("modified real duration") which measures
price changes in such bonds as a result of changes in real, rather
than nominal, interest rates. Although there is no limit on the
modified real duration of the Real Return Bond Fund, it is ex-
pected that the average modified real duration of the Fund will
normally vary approximately with the range of the average modified
real duration of all inflation-indexed bonds issued by the U.S.
Treasury in the aggregate.
TOTAL RETURN FUND invests under normal circumstances at least 65%
of its assets in a diversified portfolio of fixed income securi-
ties of varying maturities. The average portfolio duration of this
Fund will normally vary within a three- to six-year time frame
based on the Advisor's forecast for interest rates. 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 Advisor to be of comparable
quality). For information on the risks associated with investments
in securities rated below investment grade, see "Appendix B--De-
scription of Securities Ratings." 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 secu-
rities of foreign issuers. Portfolio holdings will be concentrated
in areas of the bond market (based on quality, sector, coupon or
maturity) which the Advisor believes to be relatively undervalued.
The total rate of return for this Fund is expected to exhibit less
volatility than that of the Long-Term U.S. Government Fund because
its duration will normally be shorter.
TOTAL RETURN MORTGAGE FUND invests under normal circumstances at
least 80% of its assets in a diversified portfolio of mortgage-re-
lated securities. 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 Aaa by Moody's of AAA by S&P, subject to
a minimum rating of Baa by Moody's or BBB by S&P (or, if unrated,
determined by the Advisor to be of comparable quality). The aver-
age portfolio duration of this Fund will normally vary approxi-
mately within a range of plus or minus one and one-half years of
the average duration of the Lehman Brothers Mortgage-Backed Secu-
rities Index, which, as of May 31, 1997, had an average duration
of approximately four years.
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, if unrated, determined by the
Advisor to be of comparable quality). 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 Advisor to be of comparable quality).
The average portfolio duration of this Fund will normally vary
within a two- to six-year time frame depending on the Advisor's
view of the potential for total return offered by a particular du-
ration strategy. The Fund may invest in securities of foreign is-
suers, 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
April 8, 1998 Prospectus 7
<PAGE>
downturns. The Advisor seeks to reduce risk through diversifica-
tion, 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 secu-
rities, see "Characteristics and Risks of Securities and Invest-
ment Techniques--High Yield Securities ("Junk Bonds")."
MUNICIPAL BOND FUND seeks high current income exempt from federal
income tax, consistent with preservation of capital. Capital ap-
preciation is a secondary objective. The Fund seeks its objectives
by investing in debt securities whose interest is, in the opinion
of bond counsel for the issuer at the time of issuance, exempt
from federal income tax ("Municipal Bonds"). Municipal Bonds gen-
erally are issued by states and local governments and their agen-
cies, authorities and other instrumentalities. It is a policy of
the Fund that, under normal market conditions, at least 80% of its
net assets will be invested in Municipal Bonds. The Fund may in-
vest up to 20% of its net assets in U.S. Government securities,
money market instruments and/or "private activity" bonds. Under
normal circumstances, the average portfolio duration of the Munic-
ipal Bond Fund will vary within a three- to ten-year time frame,
based on the Advisor's forecast for interest rates.
The Fund may invest up to 10% of its net assets in Municipal
Bonds or "private activity" bonds which are rated below Baa by
Moody's or BBB by S&P but which are rated at least Ba by Moody's
or BB by S&P (or, if unrated, determined by the Advisor to be of
comparable quality). For information on the risks associated with
investments in securities rated below investment grade, see "Ap-
pendix B--Description of Securities Ratings."
FOREIGN BOND FUND invests in a portfolio of fixed income securi-
ties primarily denominated in major foreign currencies and baskets
of foreign currencies (such as the European Currency Unit, or
"ECU"). The Advisor 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 con-
tracts (including related options) with respect to such securi-
ties, and options on such securities, when the Advisor 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, deter-
mined by the Advisor 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 invest-
ments in securities rated below investment grade, see "Appendix
B--Description of Securities Ratings." The average portfolio dura-
tion of this Fund will normally vary within a three- to six-year
time frame.
STOCK AND STRATEGIC BALANCED FUND has as its investment objective the maxi-
BOND FUND mization of total return, consistent with preservation of capital
DESCRIPTION and prudent investment management. In seeking to achieve this ob-
jective, the Fund invests in the securities eligible for purchase
by the StocksPLUS Fund and the Total Return Fund. The percentage
of the Fund's assets allocated to equity or fixed income exposure
will vary in accordance with an asset allocation methodology de-
veloped by the Advisor. The methodology builds upon the Advisor's
long-standing process of economic forecasting of business cycle
stages by applying to this process a disciplined asset allocation
model which employs certain statistical variance techniques. De-
pending on the outcome of this asset allocation methodology, the
Fund's equity exposure will vary between 45% and 75% of its total
assets, and its fixed income exposure will vary between 25% and
55%. There can be no assurance that the Advisor's asset allocation
methodology will be successful.
STOCK FUND STOCKSPLUS FUND, as its investment objective, seeks to achieve to-
DESCRIPTION tal return which exceeds the total return performance of the Stan-
dard & Poor's 500 Composite Stock Price Index ("S&P 500").
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
8 PIMCO Funds: Pacific Investment Management Series
<PAGE>
or exceed the performance of the S&P 500. The Advisor expects that
under normal market conditions, the Fund will invest substantially
all of its assets in S&P 500 derivatives, backed by a portfolio of
fixed income securities. The Advisor will actively manage the
fixed income assets serving as cover for derivatives, as well as
any other fixed income assets held by the Fund, with a view toward
enhancing the Fund's total return investment performance, subject
to an overall portfolio duration which is normally not expected to
exceed one year. See "Appendix A--Description of Duration."
The S&P 500 is composed of 500 selected common stocks, most of
which are listed on the New York Stock Exchange. S&P chooses the
stocks to be included in the S&P 500 solely on a statistical ba-
sis. 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. The Fund will seek to remain
invested in S&P 500 derivatives or S&P 500 stocks even when the
S&P 500 is declining.
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 Advisor
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 par-
ticular weighting in the S&P 500.
Positions in S&P 500 futures and options on futures will be en-
tered into only to the extent they constitute permissible posi-
tions for the Fund according to applicable rules of the Commodity
Futures Trading Commission ("CFTC"). From time to time, the Advi-
sor may be constrained in its ability to use S&P 500 derivatives
either by requirements of the Internal Revenue Code or by an unan-
ticipated inability to close out positions when it would be most
advantageous to do so. A large number of investors use S&P 500 de-
rivatives for both hedging and speculative purposes, and although
generally this helps guarantee a liquid market in those instru-
ments, at times liquidity may be
limited. For more information about S&P 500 derivatives, see
"Characteristics and Risks of Securities and Investment Tech-
niques--Derivative Instruments."
Assets of the StocksPLUS Fund not invested in equity securities
may be invested in securities eligible for purchase by the Fixed
Income Funds. The Fund may invest up to 10% of its assets in fixed
income securities that are 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 Advisor to be of comparable quality).
In addition, the StocksPLUS Fund may lend its portfolio securities
to brokers, dealers and other financial institutions in order to
earn income. The Fund may also invest all of its assets in deriva-
tive instruments, as described under "Characteristics of Securi-
ties and Investment Techniques--Derivative Instruments." In addi-
tion, the Fund may invest up to 20% of its assets in securities of
foreign issuers, may purchase and sell options and futures on for-
eign currencies, and may enter into forward foreign currency con-
tracts.
TOTAL The "total return" sought by certain of the Funds will consist of
RETURN AND interest and dividends from underlying securities, capital appre-
REAL RETURN ciation 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 port-
folio 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 in-
come securities (and therefore their capital appreciation or de-
preciation) is largely a function of changes in the current level
of interest rates. Generally, when interest rates are falling, a
portfolio with a shorter duration will not generate as high a
level of total return as a portfolio with a longer duration. Con-
versely, when interest rates are rising, a portfolio with a
shorter duration will generally outperform longer duration portfo-
lios. When interest rates are flat, shorter duration portfolios
generally will not generate as high a
April 8, 1998 Prospectus 9
<PAGE>
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, how-
ever, greater attendant market risk and price volatility than for
a portfolio with a shorter duration. The market value of fixed in-
come securities denominated in currencies other than the U.S. dol-
lar also may be affected by movements in foreign currency ex-
change rates.
The change in market value of equity securities (and therefore
their capital appreciation or depreciation) may depend upon a num-
ber of factors, including: conditions in the securities markets,
the business success of the security's issuer, changing interest
rates, real or perceived economic and competitive industry condi-
tions, and foreign currency exchange rates. Historically, the to-
tal return performance of equity-oriented portfolios has generally
been greater over the long term than fixed income portfolios. How-
ever, the market risk and price volatility of an equity portfolio
is generally greater than that of a fixed income portfolio, and is
generally considered to be a more aggressive investment.
"Real Return," or "Inflation Adjusted Return," as referenced in
the name and investment objective of the Real Return Bond Fund, is
a measure of the change in purchasing power of money invested in a
particular instrument after adjusting for inflation. An investment
in a security generating a high nominal return (such as a typical
U.S. Government Treasury bond) may not generate a high real return
once inflation is considered. For example, an instrument generat-
ing a 9% nominal return at a time when inflation is 6% has a real
return of approximately 3%; that is, the purchasing power of the
money invested in that instrument would only increase by approxi-
mately 3%. On the other hand, an inflation-indexed instrument gen-
erating a 5% real return would generate a 5% increase in purchas-
ing power regardless of the rate of inflation. As stated above,
the investment objective of the Fund is to seek to achieve maximum
real return. The total return (not adjusted for inflation) at-
tained by this Fund may be less than the total return attained by
other of the Funds that do not invest primarily in inflation-in-
dexed securities.
In the case of inflation-indexed bonds, changes in market value
are tied to the relationship between nominal interest rates and
the rate of inflation. If inflation were to rise at a faster rate
than nominal interest rates, real interest rates might decline,
leading to an increase in value of inflation-indexed bonds. In
contrast, if nominal interest rates increase at a faster rate than
inflation, real interest rates might increase, leading to a de-
crease in value of inflation-indexed bonds.
Investment Risks and Considerations
The following are some of the principal risks of investing in the
Funds. Investors should read this Prospectus carefully for a more
complete discussion of the risks relating to an investment in the
Funds. 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. Gen-
erally, 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, although this may not be true in the case of inflation-
indexed bonds. In addition, certain of the Funds may invest in se-
curities rated lower than Baa by Moody's or 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 posi-
tions 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 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
10 PIMCO Funds: Pacific Investment Management Series
<PAGE>
of an imperfect correlation between the value of the securities
being hedged and the value of the particular derivative instru-
ment, and the risk that unexpected changes in interest rates may
adversely affect the value of a Fund's investments in particular
derivative instruments. Unless otherwise indicated, all limita-
tions applicable to Fund investments (as stated in this Prospectus
and in the Statement of Additional Information) 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, or change in the average duration of a Fund's invest-
ment portfolio, resulting from market fluctuations or other
changes in a Fund's total assets, will not require a Fund to dis-
pose of an investment until the Advisor determines that is practi-
cable 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 Advisor will
determine which rating it believes best reflects the security's
quality and risk at that time, which may be the higher of the sev-
eral assigned ratings.
Investors should carefully consider the possible tax conse-
quences from investing in the Real Return Bond Fund. The Fund in-
vests primarily in securities that for tax purposes may be consid-
ered to have been issued originally at a discount. Accordingly,
the Fund may be required to make annual distributions to share-
holders in excess of the cash received by the Fund in a given pe-
riod from those investments. See "Characteristics and Risks of Se-
curities and Investment Techniques--Inflation-Indexed Bonds" and
"Taxes" for additional information.
The Real Return Bond and Foreign Bond Funds are "non-diversi-
fied" 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. The
Funds are still, however, subject to diversification requirements
imposed by the Internal Revenue Code of 1986, as amended, which
means that as of the end of each calendar quarter, a Fund may have
no more than 25% of its assets invested in the securities of a
single issuer, and may, with respect to 50% of its assets, have no
more than 5% of its assets invested in the securities of a single
issuer. 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.
The Funds offer their shares to both retail and institutional
investors. Institutional shareholders, some of whom also may be
investment advisory clients of Pacific Investment Management, may
hold large positions in certain of the Funds. Such shareholders
may on occasion make large redemptions of their holdings in the
Funds to meet their liquidity needs, in connection with strategic
adjustments to their overall portfolio of investments, or for
other purposes. Large redemptions from some Funds could require
the Advisor to liquidate portfolio positions when it is not most
desirable to do so. Liquidation of portfolio holdings also may
cause a Fund to realize taxable capital gains.
Characteristics and Risks of
Securities and Investment Techniques
The following describes in greater detail different types of secu-
rities 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 U.S. Government securities are obligations of, or guaranteed by,
SECURITIES 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 Na-
tional 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 is-
suer 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,
April 8, 1998 Prospectus 11
<PAGE>
are supported only by the credit of the instrumentality. U.S. Gov-
ernment securities include securities that have no coupons, or
have been stripped of their unmatured interest coupons, individual
interest coupons from such securities that trade separately, and
evidences of receipt of such securities. Such securities may pay
no cash income, and are purchased at a deep discount from their
value at maturity. Because interest on zero coupon securities is
not distributed on a current basis but is, in effect, compounded,
zero coupon securities tend to be subject to greater market risk
than interest-paying securities of similar maturities. Custodial
receipts issued in connection with so-called trademark zero coupon
securities, such as CATs and TIGRs, are not issued by the U.S.
Treasury, and are therefore not U.S. Government securities, al-
though the underlying bond represented by such receipt is a debt
obligation of the U.S. Treasury. Other zero coupon Treasury secu-
rities (STRIPs and CUBEs) are direct obligations of the U.S. Gov-
ernment.
CORPORATE Corporate debt securities include corporate bonds, debentures,
DEBT notes and other similar corporate debt instruments, including con-
SECURITIES vertible 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" below. 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 rated below
investment grade (rated below Baa (Moody's) or BBB (S&P)) are de-
scribed 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 securi-
ties rated Baa as having speculative characteristics. The Advisor
seeks to minimize these risks through diversification, in-depth
credit analysis and attention to current developments in interest
rates and market conditions. See "Appendix B--Description of Secu-
rities Ratings." Investments in high yield securities are dis-
cussed separately below under "High Yield Securities ("Junk
Bonds")."
CONVERTIBLE Each Fund (except the Municipal Bond Fund) may invest in convert-
SECURITIES ible securities, which may offer higher income than the common
stocks into which they are convertible. Typically, convertible se-
curities are callable by the company, which may, in effect, force
conversion before the holder would otherwise choose.
The convertible securities in which the Funds may invest con-
sist of bonds, notes, debentures and preferred stocks which may be
converted or exchanged at a stated or determinable exchange ratio
into underlying shares of common stock. A Fund may be required to
permit the issuer of a convertible security to redeem the securi-
ty, convert it into the underlying common stock, or sell it to a
third party. Thus, a Fund may not be able to control whether the
issuer of a convertible security chooses to convert that security.
If the issuer chooses to do so, this action could have an adverse
effect on a Fund's ability to achieve its investment objectives.
While the Fixed Income Funds intend to invest primarily in
fixed income securities, each may invest in convertible securities
or equity securities. While some countries or companies may be re-
garded as favorable investments, pure fixed income opportunities
may be unattractive or limited due to insufficient supply, legal
or technical restrictions. In such cases, a Fund may consider eq-
uity securities or convertible bonds to gain exposure to such in-
vestments.
LOAN Certain Funds may invest in fixed- and floating-rate loans ar-
PARTICIPA- ranged through private negotiations between an issuer of debt in-
TIONS AND struments and one or more financial institutions ("lenders"). Gen-
ASSIGNMENTS erally, the Funds' investments in loans are expected to take the
form of loan participations and assignments of portions of loans
from third parties.
Large loans to corporations or governments may be shared or
syndicated among several lenders, usually banks. The Funds may
participate in such syndicates, or can buy part of a loan, becom-
ing a direct lender. Participations and assignments involve spe-
cial types of risk, including limited marketability and the risks
of being a lender. See "Illiquid Securities" for a discussion of
the limits on a Fund's investments in loan participations and as-
signments with limited
12 PIMCO Funds: Pacific Investment Management Series

marketability. If a Fund purchases a participation, it may only be
able to enforce its rights through the lender, and may assume the
credit risk of the lender in addition to the borrower. In assign-
ments, the Funds' rights against the borrower may be more limited
than those held by the original lender.
DELAYED The Funds (except the PIMCO Municipal Bond Fund) may also enter
FUNDING into, or acquire participations in, delayed funding loans and re-
LOANS AND volving credit facilities. Delayed funding loans and revolving
REVOLVING credit facilities are borrowing arrangements in which the lender
CREDIT agrees to make loans up to a maximum amount upon demand by the
FACILITIES borrower during a specified term. A revolving credit facility dif-
fers from a delayed funding loan in that as the borrower repays
the loan, an amount equal to the repayment may be borrowed again
during the term of the revolving credit facility. These commit-
ments may have the effect of requiring a Fund to increase its in-
vestment in a company at a time when it might not otherwise decide
to do so (including at a time when the company's financial condi-
tion makes it unlikely that such amounts will be repaid).
The Funds may acquire a participation interest in delayed fund-
ing loans or revolving credit facilities from a bank or other fi-
nancial institution. See "Loan Participations and Assignments."
The terms of the participation require the Fund to make a pro rata
share of all loans extended to the borrower and entitles the Fund
to a pro rata share of all payments made by the borrower. Delayed
funding loans and revolving credit facilities usually provide for
floating or variable rates of interest. To the extent that a Fund
is committed to advance additional funds, it will at all times
segregate assets, determined to be liquid by the Advisor in accor-
dance with procedures established by the Board of Trustees, in an
amount sufficient to meet such commitments.
VARIABLE Variable and floating rate securities provide for a periodic ad-
AND justment in the interest rate paid on the obligations. The terms
FLOATING of such obligations must provide that interest rates are adjusted
RATE periodically based upon an interest rate adjustment index as pro-
SECURITIES vided 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") and (except the Municipal Bond Fund) en-
gage in credit spread trades. 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. A credit spread trade is an investment position relating
to a difference in the prices or interest rates of two securities
or currencies, where the value of the investment position is de-
termined by movements in the difference between the prices or in-
terest rates, as the case may be, of the respective securities or
currencies.
Each of the Fixed Income Funds (except the Municipal Bond Fund)
may also invest in inverse floating rate debt instruments ("in-
verse 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 se-
curity may exhibit greater price volatility than a fixed rate ob-
ligation of similar credit quality. The Funds have adopted a pol-
icy under which no Fund will invest more than 5% (10% in the case
of the Total Return Mortgage Fund) of its net assets in any combi-
nation 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.
INFLATION- Inflation-indexed bonds are fixed income securities whose princi-
INDEXED pal value is periodically adjusted according to the rate of infla-
BONDS tion. The interest rate on these bonds is generally fixed at issu-
ance at a rate lower than typical bonds. Over the life of an in-
flation-indexed bond, however, interest will be paid based on a
principal value which is adjusted for inflation.
Inflation-indexed securities issued by the U.S. Treasury will
initially have maturities of five or ten years, although it is an-
ticipated that securities with other maturities will be issued in
the future. The securities will pay interest on a semi-annual ba-
sis, equal to a fixed percentage of the inflation-adjusted princi-
pal amount. For example, if an investor
April 8, 1998 Prospectus 13
<PAGE>
purchased an inflation-indexed bond with a par value of $1,000 and
a 3% real rate of return coupon (payable 1.5% semi-annually), and
inflation over the first six months were 1%, the mid-year par
value of the bond would be $1,010 and the first semi-annual inter-
est payment would be $15.15 ($1,010 times 1.5%). If inflation dur-
ing the second half of the year reached 3%, the end-of-year par
value of the bond would be $1,030 and the second semi-annual in-
terest payment would be $15.45 ($1,030 times 1.5%).
If the periodic adjustment rate measuring inflation falls, the
principal value of inflation-indexed bonds will be adjusted down-
ward, and consequently the interest payable on these securities
(calculated with respect to a smaller principal amount) will be
reduced. Repayment of the original bond principal upon maturity
(as adjusted for inflation) is guaranteed in the case of U.S.
Treasury inflation-indexed bonds, even during a period of defla-
tion. However, the current market value of the bonds is not guar-
anteed, and will fluctuate. The Funds may also invest in other in-
flation related bonds which may or may not provide a similar guar-
antee. If such a guarantee of principal is not provided, the ad-
justed principal value of the bond repaid at maturity may be less
than the original principal.
The value of inflation-indexed bonds is expected to change in
response to changes in real interest rates. Real interest rates in
turn are tied to the relationship between nominal interest rates
and the rate of inflation. Therefore, if inflation were to rise at
a faster rate than nominal interest rates, real interest rates
might decline, leading to an increase in value of inflation-in-
dexed bonds. In contrast, if nominal interest rates increased at a
faster rate than inflation, real interest rates might rise, lead-
ing to a decrease in value of inflation-indexed bonds.
While these securities are expected to be protected from long-
term inflationary trends, short-term increases in inflation may
lead to a decline in value. If interest rates rise due to reasons
other than inflation (for example, due to changes in currency ex-
change rates), investors in these securities may not be protected
to the extent that the increase is not reflected in the bond's in-
flation measure.
The U.S. Treasury has only recently begun issuing inflation-in-
dexed bonds. As such, there is no trading history of these securi-
ties, and there can be no assurance that a liquid market in these
instruments will develop, although one is expected. Lack of a liq-
uid market may impose the risk of higher transaction costs and the
possibility that a Fund may be forced to liquidate positions when
it would not be advantageous to do so. There also can be no assur-
ance that the U.S. Treasury will issue any particular amount of
inflation-indexed bonds. Certain foreign governments, such as the
United Kingdom, Canada and Australia, have a longer history of is-
suing inflation-indexed bonds, and there may be a more liquid mar-
ket in certain of these countries for these securities.
The periodic adjustment of U.S. inflation-indexed bonds is tied
to the Consumer Price Index for Urban Consumers ("CPI-U"), which
is calculated monthly by the U.S. Bureau of Labor Statistics. The
CPI-U is a measurement of changes in the cost of living, made up
of components such as housing, food, transportation and energy.
Inflation-indexed bonds issued by a foreign government are gener-
ally adjusted to reflect a comparable inflation index, calculated
by that government. There can be no assurance that the CPI-U or
any foreign inflation index will accurately measure the real rate
of inflation in the prices of goods and services. Moreover, there
can be no assurance that the rate of inflation in a foreign coun-
try will be correlated to the rate of inflation in the United
States.
Any increase in the principal amount of an inflation-indexed
bond will be considered taxable ordinary income, even though in-
vestors do not receive their principal until maturity. See "Taxes"
for information about the possible tax consequences of investing
in the Real Return Bond Fund and in inflation-indexed bonds.
MORTGAGE- Each of the Funds (except the Municipal Bond Fund) may invest all
RELATED AND of its assets in mortgage- or other asset-backed securities. The
OTHER value of some mortgage- or asset-backed securities in which the
ASSET- Funds invest may be particularly sensitive to changes in prevail-
BACKED ing interest rates, and, like the other investments of the Funds,
SECURITIES the ability of a Fund to successfully utilize these instruments
may depend in part upon the ability of the Advisor to forecast in-
terest rates and other economic factors correctly.
14 PIMCO Funds: Pacific Investment Management Series
<PAGE>
MORTGAGE-PASS-THROUGH SECURITIES are securities representing in-
terests in "pools" of mortgage loans secured by residential or
commercial real property in which payments of both interest and
principal on the securities are generally made monthly, in effect
"passing through" monthly payments made by the individual borrow-
ers on the mortgage loans which underlie the securities (net of
fees paid to the issuer or guarantor of the securities). Early re-
payment of principal on some mortgage-related securities (arising
from prepayments of principal due to sale of the underlying prop-
erty, refinancing, or foreclosure, net of fees and costs which may
be incurred) may expose a Fund to a lower rate of return upon re-
investment of principal. Also, if a security subject to prepayment
has been purchased at a premium, the value of the premium would be
lost in the event of prepayment. Like other fixed income securi-
ties, 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 prepay-
ment features may not increase as much as other fixed income secu-
rities. The rate of prepayments on underlying mortgages will af-
fect the price and volatility of a mortgage-related security, and
may have the effect of shortening or extending the effective matu-
rity of the security beyond what was anticipated at the time of
purchase. To the extent that unanticipated rates of prepayment on
underlying mortgages increase the effective maturity of a mort-
gage-related security, the volatility of such security can be ex-
pected to increase.
Payment of principal and interest on some mortgage pass-through
securities (but not the market value of the securities themselves)
may be guaranteed by the full faith and credit of the U.S. Govern-
ment (in the case of securities guaranteed by 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 bank-
ers and other secondary market issuers) may be supported by vari-
ous 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 mort-
gage poolers.
COLLATERALIZED MORTGAGE OBLIGATIONS ("CMOs") are hybrid mortgage-
related instruments. Interest and pre-paid principal on a CMO are
paid, in most cases, on a monthly basis. CMOs may be collateral-
ized 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 pay-
ments 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 re-
flect an interest in, and are secured by, mortgage loans on com-
mercial real property. The market for commercial mortgage-backed
securities developed more recently and in terms of total outstand-
ing principal amount of issues is relatively small compared to the
market for residential single-family mortgage-backed securities.
Many of the risks of investing in commercial mortgage-backed secu-
rities reflect the risks of investing in the real estate securing
the underlying mortgage loans. These risks reflect the effects of
local and other economic conditions on real estate markets, the
ability of tenants to make loan payments, and the ability of a
property to attract and retain tenants. Commercial mortgage-backed
securities may be less liquid and exhibit greater price volatility
than other types of mortgage-related or asset-backed securities.
MORTGAGE-RELATED SECURITIES include securities other than those
described above that directly or indirectly represent a participa-
tion in, or are secured by and payable from, mortgage loans on
real property, such as mortgage dollar rolls (see "Reverse Repur-
chase Agreements, Dollar Rolls, and Borrowings"), CMO residuals or
stripped mortgage-backed securities ("SMBS"), and may be struc-
tured in classes with rights to receive varying proportions of
principal and interest.
April 8, 1998 Prospectus 15
<PAGE>
A common type of SMBS will have one class receiving some of the
interest and most of the principal from the mortgage assets, while
the other class will receive most of the interest and the remain-
der of the principal. In the most extreme case, one class will re-
ceive all of the interest (the interest-only, or "IO" class),
while the other class will receive all of the principal (the prin-
cipal-only, or "PO" class). The yield to maturity on an IO class
is extremely sensitive to the rate of principal payments (includ-
ing prepayments) on the related underlying mortgage assets, and a
rapid rate of principal payments may have a material adverse ef-
fect on a Fund's yield to maturity from these securities. The
Funds have adopted a policy under which no Fund will invest more
than 5% (10% in the case of the Total Return Mortgage Fund) of its
net assets in any combination of IO, PO, or inverse floater secu-
rities. The Funds may invest in other asset-backed securities that
have been offered to investors. For a discussion of the character-
istics of some of these instruments, see the Statement of Addi-
tional Information.
MUNICIPAL The Municipal Bond Fund invests in Municipal Bonds which are gen-
BONDS erally issued by states and local governments and their agencies,
authorities and other instrumentalities. The Municipal Bonds which
the Municipal Bond Fund may purchase include general obligation
bonds and limited obligation bonds (or revenue bonds), including
industrial development bonds issued pursuant to former federal tax
law. General obligation bonds are obligations involving the credit
of an issuer possessing taxing power and are payable from such is-
suer's general revenues and not from any particular source. Lim-
ited obligation bonds are payable only from the revenues derived
from a particular facility or class of facilities or, in some
cases, from the proceeds of a special excise or other specific
revenue source. Tax-exempt "private activity" bonds and industrial
development bonds generally are also revenue bonds and thus are
not payable from the issuer's general revenues. The Municipal Bond
Fund may invest in Municipal Bonds with credit enhancements such
as letters of credit, municipal bond insurance and Standby Bond
Purchase Agreements. The Municipal Bond Fund may also invest in
municipal lease obligations, as well as securities derived from
Municipal Bonds, such as residual interest bonds, and participa-
tion interests.
Municipal Bonds are subject to credit and market risk. Credit
risk relates to the ability of the issuer to make payments of
principal and interest. The ability of an issuer to make such pay-
ments could be affected by litigation, legislation or other polit-
ical events or the bankruptcy of the issuer. Market risk relates
to changes in a security's value as a result of changes in inter-
est rates. Lower rated Municipal Bonds generally provide higher
yields but are subject to greater credit and market risk than
higher quality Municipal Bonds.
REPURCHASE For the purpose of achieving income, each of the Funds may enter
AGREEMENTS into repurchase agreements, which entail the purchase of a portfo-
lio-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 repur-
chase 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 A reverse repurchase agreement involves the sale of a security by
REPURCHASE a Fund and its agreement to repurchase the instrument at a speci-
AGREEMENTS, fied time and price. Under a reverse repurchase agreement, the
DOLLAR Fund continues to receive any principal and interest payments on
ROLLS, AND the underlying security during the term of the agreement. The Fund
BORROWINGS generally will maintain a segregated account consisting of assets
determined to be liquid by the Advisor in accordance with proce-
dures established by the Board of Trustees to cover its obliga-
tions under reverse repurchase agreements and, to this extent, a
reverse repurchase agreement (or economically similar transaction)
will not be considered a "senior security" subject to the 300% as-
set coverage requirements otherwise applicable to borrowings by a
Fund.
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 simi-
lar 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
16 PIMCO Funds: Pacific Investment Management Series
<PAGE>
same type and will have the same interest rate as those sold, but
will be supported by different pools of mortgages. The Fund for-
goes principal and interest paid during the roll period on the se-
curities 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 pro-
ceeds 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
assets determined to be liquid by the Advisor in accordance with
procedures established by the Board of Trustees to cover its obli-
gations under dollar rolls.
To the extent that positions in reverse repurchase agreements,
dollar rolls or similar transactions are not covered through the
maintenance of a segregated account consisting of liquid assets at
least equal to the amount of any forward purchase commitment, such
transactions would be subject to the Funds' limitations on
borrowings, which would restrict
the aggregate of such transactions (plus any other borrowings) to
33 1/3% of such Fund's total assets. Apart from such transactions,
a Fund will not borrow money, except for temporary administrative
purposes.
LOANS OF For the purpose of achieving income, each Fund may lend its port-
PORTFOLIO folio securities to brokers, dealers, and other financial institu-
SECURITIES tions, provided:
(i) the loan is secured continuously by collateral consisting
of U.S. Government securities, cash or cash equivalents
(negotiable certificates of deposit, bankers' acceptances
or letters of credit) maintained on a daily mark-to-market
basis in an amount at least equal 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 33 1/3% of the total assets of the
Fund.
Each Fund's performance will continue to reflect changes in the
value of the securities loaned and will also reflect the receipt
of either interest, through investment of cash collateral by the
Fund in permissible investments, or a fee, if the collateral is
U.S. Government securities. Securities lending involves the risk
of loss of rights in the collateral or delay in recovery of the
collateral should the borrower fail to return the security loaned
or become insolvent. The Funds may pay lending fees to the party
arranging the loan.
WHEN- Each of the Funds may purchase or sell securities on a when-is-
ISSUED, sued, delayed delivery, or forward commitment basis. These trans-
DELAYED actions involve a commitment by the Fund to purchase or sell secu-
DELIVERY rities for a predetermined price or yield, with payment and deliv-
AND FORWARD ery taking place more than seven days in the future, or after a
COMMITMENT period longer than the customary settlement period for that type
TRANSAC- of security. When such purchases are outstanding, the Fund will
TIONS set aside and maintain until the settlement date in a segregated
account, assets determined to be liquid by the Advisor in accor-
dance with procedures established by the Board of Trustees, in an
amount sufficient to meet the purchase price. Typically, no income
accrues on securities a Fund has committed to purchase prior to
the time delivery of the securities is made, although a Fund may
earn income on securities it has deposited in a segregated ac-
count. When purchasing a security on a when-issued, delayed deliv-
ery, or forward commitment 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 re-
quired 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 in-
vested at a time when when-issued, delayed delivery, or forward
commitment purchases are outstanding, the purchases may result in
a form of leverage. When the Fund has sold a security on a when-
issued, delayed delivery, or forward commitment basis, the Fund
does not participate in future gains or losses with respect to the
security. If the other party to a 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 transaction after it is entered into, and may sell
when-issued or forward commitment securities before they are de-
livered, which may result in a capital gain or loss. There is no
percentage limitation on the extent to which the Funds may pur-
chase or sell securities on a when-issued, delayed delivery, or
forward commitment basis.

SHORT SALES Each of the Funds (except the High Yield and StocksPLUS 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 po-
sitions 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 as-
set coverage in the form of assets determined to be liquid by the
Advisor in accordance with procedures established by the Board of
Trustees, 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 Each of the Funds (except the Municipal Bond Fund) may invest di-
SECURITIES rectly in fixed income securities of non-U.S. issuers. The Total
Return Mortgage and High Yield Funds may only invest in U.S. dol-
lar-denominated fixed income securities of non-U.S. issuers. The
StocksPLUS Fund may invest directly in foreign equity securities.
Each of the Funds will concentrate its foreign investments in
securities of issuers based in developed countries. However, the
Short-Term and Low Duration Funds may each invest up to 5% of its
assets in securities of issuers based in emerging market coun-
tries, and each of the remaining Fixed Income Funds that may in-
vest in foreign securities may invest up to 10% of its assets in
such securities.
Individual foreign economies may differ favorably or unfavor-
ably from the U.S. economy in such respects as growth of gross do-
mestic product, rate of inflation, capital reinvestment, re-
sources, self-sufficiency and balance of payments position. The
securities markets, values of securities, yields, and risks asso-
ciated with securities markets in different countries may change
independently of each other. Investing in the securities of is-
suers in any foreign country involves special risks and considera-
tions not typically associated with investing in U.S. companies.
Shareholders should consider carefully the substantial risks in-
volved in investing in securities issued by companies and govern-
ments of foreign nations. These risks include: differences in ac-
counting, auditing and financial reporting standards; generally
higher commission rates on foreign portfolio transactions; the
possibility of nationalization, expropriation or confiscatory tax-
ation; adverse changes in investment or exchange control regula-
tions (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, for-
eign securities and dividends and interest payable on those secu-
rities 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 there-
fore may exhibit greater price volatility. Additional costs asso-
ciated 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 for-
eign exchange rates also will affect the value of securities de-
nominated or quoted in currencies other than the U.S. dollar.
Certain of the Funds will invest in the securities of issuers
based in countries with developing economies. Investing in devel-
oping (or "emerging market") countries involves certain risks not
typically associated with investing in U.S. securities, and im-
poses risks greater than, or in addition to, risks of investing in
foreign, developed countries. A number of emerging market coun-
tries restrict, to varying degrees, foreign investment in securi-
ties. Repatriation of investment income, capital, and the proceeds
of sales by foreign investors may require governmental registra-
tion and/or approval in some emerging market countries. A number
of the currencies of emerging market countries have experienced
significant declines against the U.S. dollar in recent years, and
devaluation may occur subsequent to investments in these curren-
cies by a Fund. Inflation and rapid fluctuations in inflation
rates have had, and may continue to have, negative effects on the
economies and securities markets of certain emerging market coun-
tries. Many of the emerging securities markets are relatively
small, have low trading volumes, suffer periods of relative illi-
quidity, and are characterized by significant price volatility.
There is a risk in emerging market countries that a future eco-
nomic or political crisis could lead to price controls, forced
mergers of companies, expropriation or confiscatory taxation, sei-
zure, nationalization, or creation of government monopolies, any
of which may have a detrimental effect on a Fund's investment.
18 PIMCO Funds: Pacific Investment Management Series
<PAGE>
Additional risks of investing in emerging market countries may
include: currency exchange rate fluctuations; greater social, eco-
nomic and political uncertainty and instability (including the
risk of war); more substantial governmental involvement in the
economy; less governmental supervision and regulation of the secu-
rities markets and participants in those markets; unavailability
of currency hedging techniques in certain emerging market coun-
tries; the fact that companies in emerging market countries may be
newly organized and may be smaller and less seasoned companies;
the difference in, or lack of, auditing and financial reporting
standards, which may result in unavailability of material informa-
tion about issuers; the risk that it may be more difficult to ob-
tain and/or enforce a judgment in a court outside the United
States; and significantly smaller market capitalization of securi-
ties markets. Also, any change in the leadership or policies of
Eastern European countries, or the countries that exercise a sig-
nificant influence over those countries, may halt the expansion of
or reverse the liberalization of foreign investment policies now
occurring and adversely affect existing investment opportunities.
In addition, emerging securities markets may have different
clearance and settlement procedures, which may be unable to keep
pace with the volume of securities transactions or otherwise make
it difficult to engage in such transactions. Settlement problems
may cause a Fund to miss attractive investment opportunities, hold
a portion of its assets in cash pending investment, or delay in
disposing of a portfolio security. Such a delay could result in
possible liability to a purchaser of the security.
Each of the Fixed Income Funds (except the Municipal Bond Fund)
may invest in Brady Bonds. Brady Bonds are securities created
through the exchange of existing commercial bank loans to sover-
eign entities for new obligations in connection with debt
restructurings under a debt restructuring plan introduced by for-
mer 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. Gov-
ernment 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 in-
formation, see the Statement of Additional Information.
Certain of the Funds also may invest in sovereign debt (other
than Brady Bonds) issued by governments, their agencies or instru-
mentalities, or other government-related entities located in
emerging market countries. Holders of sovereign debt may be re-
quested to participate in the rescheduling of such debt and to ex-
tend further loans to governmental entities. In addition, there is
no bankruptcy proceeding by which defaulted sovereign debt may be
collected.
A Fund's investments in foreign currency denominated debt obli-
gations and hedging activities will likely produce a difference
between its book income and its taxable income. This difference
may cause a portion of the Fund's income distributions to consti-
tute returns of capital for tax purposes or require the Fund to
make distributions exceeding book income to qualify as a regulated
investment company for federal tax purposes.
FOREIGN Foreign currency exchange rates may fluctuate significantly over
CURRENCY short periods of time. They generally are determined by the forces
TRANS- of supply and demand in the foreign exchange markets and the rela-
ACTIONS tive merits of investments in different countries, actual or per-
ceived changes in interest rates and other complex factors, as
seen from an international perspective. Currency exchange rates
also can be affected unpredictably by intervention (or the failure
to intervene) by U.S. or foreign governments or central banks, by
currency controls or political developments in the U.S. or abroad.
For example, significant uncertainty surrounds the proposed intro-
duction of the euro (a common currency for the European Union) in
January 1999 and its effect on the value of securities denominated
in local European currencies. These and other currencies in which
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 buy and sell foreign currencies on a spot and for-
ward basis to reduce the risks of adverse changes in foreign ex-
change rates. A forward foreign currency
April 8, 1998 Prospectus 19
<PAGE>
exchange contract involves an obligation to purchase or sell a
specific currency at a future date, which may be any fixed number
of days from the date of the contract agreed upon by the parties,
at a price set at the time of the contract. By entering into a
forward foreign currency exchange contract, the Fund "locks in"
the exchange rate between the currency it will deliver and the
currency it will receive for the duration of the contract. As a
result, a Fund reduces its exposure to changes in the value of the
currency it will deliver and increases its exposure to changes in
the value of the currency it will exchange into. 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 cur-
rency 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 denomi-
nated in foreign currencies. A Fund also may enter into these con-
tracts for purposes of increasing exposure to a foreign currency
or to shift exposure to foreign currency fluctuations from one
country to another. A Fund may use one currency (or a basket of
currencies) to hedge against adverse changes in the value of an-
other currency (or a basket of currencies) when exchange rates be-
tween the two currencies are positively correlated. Each Fund will
segregate assets determined to be liquid by the Advisor in accor-
dance with procedures established by the Board of Trustees, in a
segregated account to cover its obligations under forward foreign
currency exchange contracts entered into for non-hedging purposes.
All Funds that may invest in securities denominated in foreign
currencies may invest in options on foreign currencies and foreign
currency futures and options thereon. 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. Each Fund that may invest in se-
curities denominated in foreign currencies, except the Emerging
Markets Bond Fund, will use these techniques to hedge at least 75%
of its exposure to foreign currency. For a description of these
instruments, see "Derivative Instruments" below and the Statement
of Additional Information.
HIGH YIELD The High Yield Fund invests at least 65% of its assets in fixed
SECURITIES income securities rated lower than Baa by Moody's or lower than
("JUNK BBB by S&P but rated at least B by Moody's or S&P (or, if not rat-
BONDS") ed, of comparable quality). In addition, each of the Short-Term,
Low Duration, Total Return, Foreign Bond, Strategic Balanced and
StocksPLUS Funds may invest up to 10% of its assets in such secu-
rities. The Municipal Bond Fund may invest up to 10% of its assets
in securities rated lower than Baa by Moody's or BBB by S&P but
rated at least Ba by Moody's or BB by S&P. Securities rated lower
than Baa by Moody's or lower than BBB by S&P are sometimes re-
ferred to as "high yield" or "junk" bonds. Securities rated Baa
are considered by Moody's to have some speculative characteris-
tics. 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 per-
ceived 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 ex-
ample, 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 periodi-
cally and in cash.
20 PIMCO Funds: Pacific Investment Management Series
<PAGE>
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.
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
Advisor does not rely solely on credit ratings when selecting se-
curities 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 Advisor deems it in the best inter-
est of shareholders.
During the year ended March 31, 1997, based upon the dollar-
weighted average ratings of the Funds' portfolio holdings at the
end of each month in the Funds' fiscal year, each operational 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 Advisor to be
of comparable quality). See "Appendix B--Description of Securities
Ratings," for further information.

DERIVATIVE To the extent permitted by the investment objectives and policies
INSTRUMENTS of the Funds, the Funds may purchase and write call and put op-
tions on securities, securities indexes and foreign currencies,
and enter into futures contracts and use options on futures con-
tracts as further described below. The Funds (except the Municipal
Bond Fund) 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 inter-
est rates, foreign currency exchange rates or securities prices or
as part of their overall investment strategies. The Funds (except
the Municipal Bond Fund) may also purchase and sell options relat-
ing to foreign currencies for purposes of increasing exposure to a
foreign currency or to shift exposure to foreign currency fluctua-
tions from one country to another. Each Fund will maintain a seg-
regated account consisting of assets determined to be liquid by
the Advisor in accordance with procedures established by the Board
of Trustees (or, as permitted by applicable regulation, enter into
certain offsetting positions) to cover its obligations under op-
tions, futures, and swaps to limit leveraging of the Fund.

Derivative instruments are considered for these purposes 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 depends upon cash flows from underlying assets,
such as mortgage-related or asset-backed securities. Each Fund
(except the Municipal Bond Fund) may invest all of its assets in
derivative instruments, subject only to the Fund's investment ob-
jective 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 instru-
ments may depend in part upon the ability of the Advisor to fore-
cast interest rates and other economic factors correctly. If the
Advisor 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 loss.
The Funds might not employ any of the strategies described be-
low, and no assurance can be given that any strategy used will
succeed. If the Advisor incorrectly forecasts interest rates, mar-
ket 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 pos-
sible imperfect correlation, or even no correlation, between price
movements of derivative instruments and price movements of related
investments. While some strategies involving derivative instru-
ments can reduce the risk of loss, they can also reduce the oppor-
tunity for gain or even result in losses by offsetting favorable
price movements in related investments or otherwise, due to the
possible inability of a Fund to purchase or sell a portfolio secu-
rity at a time that otherwise would be favorable or the possible
need to sell a portfolio security at a disadvantageous time be-
cause the Fund is required to maintain asset coverage or offset-
ting positions in connection with transactions in derivative in-
struments, 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 and indexes. 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 and indexes. One
purpose of purchasing call options is to protect against substan-
tial increases in prices of securities the Fund intends to pur-
chase pending its ability to invest in such securities in an or-
derly manner. An option on a security (or index) is a contract
that gives the holder of the option, in return for a premium, the
right to buy from (in the case of a call) or sell to (in the case
of a put) the writer of the option the security underlying the op-
tion (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 op-
tion to deliver the underlying security upon payment of the exer-
cise price or to pay the exercise price upon delivery of the un-
derlying 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 mul-
tiplier 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 may sell put or call options it has previously pur-
chased, 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 under-
lying 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 combina-
tion 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 ex-
ercise 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."
22 PIMCO Funds: Pacific Investment Management Series
<PAGE>
The purchase and writing of options involves certain risks.
During the option period, the covered call writer has, in return
for the premium on the option, given up the opportunity to profit
from a price increase in the underlying security above the exer-
cise price, but, as long as its obligation as a writer continues,
has retained the risk of loss should the price of the underlying
security decline. The writer of an option has no control over the
time when it may be required to fulfill its obligation as a writer
of the option. Once an option writer has received an exercise no-
tice, it cannot effect a closing purchase transaction in order to
terminate its obligation under the option and must deliver the un-
derlying security at the exercise price. If a put or call option
purchased by the Fund is not sold when it has remaining value, and
if the market price of the underlying security remains equal to or
greater than the exercise price (in the case of a put), or remains
less than or equal to the exercise price (in the case of a call),
the Fund will lose its entire investment in the option. Also,
where a put or call option on a particular security is purchased
to hedge against price movements in a related security, the price
of the put or call option may move more or less than the price of
the related security. There can be no assurance that a liquid mar-
ket will exist when a Fund seeks to close out an option position.
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. Cur-
rency 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 in which certain Funds may invest dif-
fer 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 cer-
tain written over-the-counter options.
SWAP AGREEMENTS The Funds (except the Municipal Bond Fund) may en-
ter 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 desir-
able to do so, possibly at a lower cost to the Fund than if the
Fund had invested directly in the asset that yielded the desired
return. Swap agreements are two-party contracts entered into pri-
marily 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 invest-
ments or instruments, which may be adjusted for an interest fac-
tor. 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 partic-
ular 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 ex-
ceed 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 speci-
fied level, or "floor"; and interest rate collars, under which a
party sells a cap and purchases a floor or vice versa in an at-
tempt to protect itself against interest rate movements exceeding
given minimum or maximum levels.
Most swap agreements entered into by the Funds calculate the
obligations of the parties to the agreement on a "net basis." Con-
sequently, a Fund's current obligations (or rights) under a swap
agreement will generally be equal only to the net amount to be
paid or received under the agreement based on the relative values
of the positions held by each party to the agreement (the "net
amount"). A Fund's current obligations under a swap agreement will
be accrued daily (offset against amounts owed to the Fund), and
any accrued but unpaid net amounts owed to a swap counterparty
will be covered by the maintenance of a segregated account con-
sisting of assets determined to be liquid by the Advisor in accor-
dance with procedures established by the Board of Trustees, to
limit any potential leveraging of the Fund's portfolio. Obliga-
tions under swap agreements so covered will not be construed to be
"senior securities" for purposes of the Funds' investment restric-
tion concerning senior securities. A Fund will not enter into a
swap agreement with any single party if the net amount owed or to
be received under existing contracts with that party would exceed
5% of the Fund's assets.

Whether a Fund's use of swap agreements will be successful in
furthering its investment objective will depend on the Advisor's
ability to predict correctly whether certain types of investments
are likely to produce greater returns than other investments. Be-
cause 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 In-
ternal 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 Each of the
Fixed Income Funds (except the Municipal Bond Fund) may invest in
interest rate futures contracts and options thereon ("futures op-
tions"), and to the extent it may invest in foreign currency-de-
nominated securities, may also invest in foreign currency futures
contracts and options thereon. The Municipal Bond Fund may pur-
chase and sell futures contracts on U.S. Government securities and
Municipal Bonds, as well as purchase put and call options on such
futures contracts. The StocksPLUS Fund may invest in interest
rate, stock index and foreign currency futures contracts and op-
tions thereon.
There are several risks associated with the use of futures and
futures options for hedging purposes. There can be no guarantee
that there will be a correlation between price movements in the
hedging vehicle and in the portfolio securities being hedged. An
incorrect correlation could result in a loss on both the hedged
securities in a Fund and the hedging vehicle, so that the portfo-
lio return might have been greater had hedging not been attempted.
There can be no assurance that a liquid market will exist at a
time when a Fund seeks to close out a futures contract or a
futures option position. Most futures exchanges and boards of
trade limit the amount of fluctuation permitted in futures con-
tract prices during a single day; once the daily limit has been
reached on a particular contract, no trades may be made that day
at a price beyond that limit. In addition, certain of these in-
struments are relatively new and without a significant trading
history. As a result, there is no assurance that an active second-
ary market will develop or continue to exist. Lack of a liquid
market for any reason may prevent a Fund from liquidating an unfa-
vorable position, and the Fund would remain obligated to meet mar-
gin requirements until the position is closed.
The Funds 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 as-
sets 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 op-
tions which are standardized and traded on a U.S. or foreign ex-
change or board of trade, or similar entity, or quoted on an auto-
mated quotation system. Each Fund will use financial futures con-
tracts and related options only for "bona fide hedging" purposes,
as such term is defined in applicable regulations of the CFTC or,
with respect to positions in financial futures and related options
that do not qualify as "bona fide hedging" positions, will enter
such positions only to the extent that aggregate initial margin
deposits plus premiums paid by it for open futures option posi-
tions, less the amount by which any such positions are "in-the-
money," would not exceed 5% of the Fund's net assets.
HYBRID A hybrid instrument can combine the characteristics of securities,
INSTRUMENTS futures, and options. For example, the principal amount or inter-
est rate of a hybrid could be tied (positively or negatively) to
the price of some commodity, currency or securities index or an-
other interest rate (each a "benchmark"). The interest rate or
(unlike most fixed income securi-
24 PIMCO Funds: Pacific Investment Management Series
<PAGE>
ties) the principal amount payable at maturity of a hybrid secu-
rity may be increased or decreased, depending on changes in the
value of the benchmark.
Hybrids can be used as an efficient means of pursuing a variety
of investment goals, including currency hedging, duration manage-
ment, and increased total return. Hybrids may not bear interest or
pay dividends. The value of a hybrid or its interest rate may be a
multiple of a benchmark and, as a result, may be leveraged and
move (up or down) more steeply and rapidly than the benchmark.
These benchmarks may be sensitive to economic and political
events, such as commodity shortages and currency devaluations,
which cannot be readily foreseen by the purchaser of a hybrid. Un-
der certain conditions, the redemption value of a hybrid could be
zero. Thus, an investment in a hybrid may entail significant mar-
ket risks that are not associated with a similar investment in a
traditional, U.S. dollar-denominated bond that has a fixed princi-
pal amount and pays a fixed rate or floating rate of interest. The
purchase of hybrids also exposes a Fund to the credit risk of the
issuer of the hybrids. These risks may cause significant fluctua-
tions in the net asset value of the Fund. Accordingly, no Fund
will invest more than 5% of its assets in hybrid instruments.
Certain issuers of structured products such as hybrid instru-
ments may be deemed to be investment companies as defined in the
1940 Act. As a result, the Funds' investments in these products
will be subject to limits applicable to investments in investment
companies and may be subject to restrictions contained in the 1940
Act.
INVESTMENT Each of the Funds may invest in securities of other investment
IN companies, such as closed-end management investment companies, or
INVESTMENT in pooled accounts or other investment vehicles. As a shareholder
COMPANIES of an investment company, a Fund may indirectly bear service and
other fees which are in addition to the fees the Fund pays its
service providers.
PORTFOLIO The length of time a Fund has held a particular security is not
TURNOVER generally a consideration in investment decisions. The investment
policies of a Fund may lead to frequent changes in the Fund's in-
vestments, particularly in periods of volatile market movements.
High portfolio turnover (e.g., over 100%) involves correspondingly
greater expenses to a Fund, including commissions or dealer mark-
ups and other transaction costs on the sale of securities and
reinvestments in other securities. See "Management of the Trust--
Portfolio Transactions." Such sales may result in realization of
taxable capital gains. See "Taxes." The portfolio turnover rate
for the following Funds for the last two fiscal years (1997 and
1996, respectively) was: Short-Term--77% and 215%; Low Duration--
240% and 209%; Total Return--173% and 221%; High Yield--67% and
66%; and Foreign Bond--984% and 1,234%.
ILLIQUID Each of the Funds may invest up to 15% of its net assets in illiq-
SECURITIES uid securities. Certain illiquid securities may require pricing at
fair value as determined in good faith under the supervision of
the Board of Trustees. The Advisor may be subject to significant
delays in disposing of illiquid securities, and transactions in
illiquid securities may entail registration expenses and other
transaction costs that are higher than those for transactions in
liquid securities. The term "illiquid securities" for this purpose
means securities that cannot be disposed of within seven days in
the ordinary course of business at approximately the amount at
which a Fund has valued the securities. Illiquid securities are
considered to include, among other things, written over-the-
counter options, securities or other liquid assets being used as
cover for such options, repurchase agreements with maturities in
excess of seven days, certain loan participation interests, fixed
time deposits which are not subject to prepayment or provide for
withdrawal penalties upon prepayment (other than overnight depos-
its), securities that are subject to legal or contractual restric-
tions on resale and other securities which legally or in the Advi-
sor's opinion may be deemed illiquid (not including securities is-
sued pursuant to Rule 144A under the Securities Act of 1933 and
certain commercial paper that Pacific Investment Management has
determined to be liquid under procedures approved by the Board of
Trustees).
Illiquid securities may include privately placed securities,
which are sold directly to a small number of investors, usually
institutions. Unlike public offerings, such securities are not
registered under the federal securities laws. Although certain of
these securities may be readily sold, for example, under Rule
144A, others may be illiquid, and their sale may involve substan-
tial delays and additional costs.

SERVICE Many of the services provided to the Funds depend on the smooth
SYSTEMS-- functioning of computer systems. Many systems in use today cannot
YEAR 2000 distinguish between the year 1900 and the year 2000. Should any of
PROBLEM the service systems fail to process information properly, that
could have an adverse impact on the Funds' operations and services
provided to shareholders. The Advisor, Distributor, Shareholder
Servicing and Transfer Agent, Custodian, and certain other service
providers to the Funds have reported that each is working toward
mitigating the risks associated with the so-called "year 2000
problem." However, there can be no assurance that the problem will
be corrected in all respects and that the Funds' operations and
services provided to shareholders will not be adversely affected.
Performance Information
From time to time the Trust may make available certain information
about the performance of the Class D shares of some or all of the
Funds. Information about a Fund's performance is based on that
Fund's (or its predecessor's) record to a recent date and is not
intended to indicate future performance.
From time to time, the yield and total return for each class of
shares of the Funds may be included in advertisements or reports
to shareholders or prospective investors. 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 invest-
ment income"), and will be computed by dividing net investment in-
come by the maximum public offering price per share on the last
day of the period. The tax equivalent yield of the Municipal Bond
Fund's Class D shares may also be advertised, calculated like
yield except that, for any given tax bracket, net investment in-
come will be calculated as the sum of (i) any taxable income of
the class plus (ii) the tax exempt income of the class divided by
the difference between 1 and the effective federal income tax
rates for taxpayers in that tax bracket.
The total return of Class D shares of all Funds may be included
in advertisements or other written material. When a Fund's total
return is advertised with respect to its Class D shares, it will
be calculated for the past year, the past five years, and the past
ten years (or if the Fund has been offered for a period shorter
than one, five or ten years, that period will be substituted)
since the establishment of the Fund as more fully described in the
Statement of Additional Information. Consistent with Securities
and Exchange Commission rules and informal guidance, for periods
prior to the initial offering date of Class D shares, total return
presentations for the Class D shares will be based on the histori-
cal performance of an older class of the Fund (the older class to
be used in each case is set forth in the Statement of Additional
Information) restated, as necessary, to reflect that there are no
sales charges associated with Class D shares, but not reflecting
any different operating expenses (such as administrative fee
and/or 12b-1/servicing fee charges) associated with Class D
shares. All other things being equal, any higher expenses of Class
D shares would have adversely affected (i.e., reduced) total re-
turn for Class D shares (i.e., if the Class D shares had been is-
sued since the inception of the Fund) by the amount of such higher
expenses, compounded over the relevant period. Total return is
measured by comparing the value of an investment in Class D shares
of the Fund at the beginning of the relevant period to the redemp-
tion value of the investment in the Fund at the end of the period
(assuming immediate reinvestment of any dividends or capital gains
distributions at net asset value). Total return may be advertised
using alternative methods that reflect all elements of return, but
that may be adjusted to reflect the cumulative impact of alterna-
tive fee and expense structures, such as the currently effective
advisory and administrative fees for Class D shares of the Funds.
The Funds may also provide current distribution information to
its shareholders in shareholder reports or other shareholder com-
munications, or in certain types of sales literature provided to
prospective investors. Current distribution information for a
Class D shares of a Fund will be based on distributions for a
specified period (i.e., total dividends from net investment in-
come), divided by the net asset value per Class D share on the
last day of the period and annualized. The rate of current distri-
butions 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
26 PIMCO Funds: Pacific Investment Management Series
<PAGE>
yield rates in that they represent what Class D shares of a Fund
have declared and paid to shareholders as of the end of a speci-
fied 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 indexes, such as the S&P 500, the Lehman Broth-
ers Aggregate Bond Index, the Lehman Brothers Mortgage-Backed Se-
curities Index, the Merrill Lynch 1 to 3 Year Treasury Index, the
Lehman Intermediate and 20+ Year Treasury Blend Index, the Lehman
Inflation Linked Treasury Index, the Lehman Muncipal Bond Index,
the Lehman BB Intermediate Corporate Index, indexes prepared by
Lipper Analytical Services, the J.P. Morgan Global Index, the J.P.
Morgan Emerging Markets Bond Index Plus, the Salomon Brothers
World Government Bond Index-10 Non U.S.-Dollar Hedged and the J.P.
Morgan Government Bond Index Non U.S.-Dollar Hedged, and other en-
tities or organizations which track the performance of investment
companies or investment advisers. Unmanaged indexes (i.e., other
than Lipper) generally do not reflect deductions for administra-
tive and management costs and expenses. The Advisor may also re-
port to shareholders or to the public in advertisements concerning
the performance of the Advisor as adviser to clients other than
the Trust, and on the comparative performance or standing of the
Advisor in relation to other money managers. Such comparative in-
formation may be compiled or provided by independent ratings serv-
ices or by news organizations. Any performance information,
whether related to the Funds or to the Advisor, should be consid-
ered in light of the Funds' investment objectives and policies,
characteristics and quality of the portfolio, and the market con-
ditions during the time period indicated, and should not be con-
sidered to be representative of what may be achieved in the fu-
ture. For a description of the methods used to determine yield and
total return for the Funds, see the Statement of Additional Infor-
mation.
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 in-
vestor's total return or yield may be in any future period.
How to Buy Shares
Class D shares of each Fund are continuously offered through fi-
nancial service firms, such as broker-dealers or registered in-
vestment advisers, with which the Trust's principal underwriter,
PIMCO Funds Distributors LLC (the "Distributor"), has an agreement
for the use of the Funds in particular investment products, pro-
grams or accounts for which a fee may be charged. See "Financial
Service Firms" below.
You may purchase Class D shares only through your financial
service firm. In connection with purchases, your financial service
firm is responsible for forwarding all necessary documentation to
the Distributor, and may charge you for such services. Investors
who wish to purchase shares of the Funds directly from the Trust
or the Distributor should inquire as to the other classes of
shares. See "Description of the Trust--Multiple Classes of
Shares."
Class D shares may be purchased at a price equal to their net
asset value per share next determined after receipt of an order.
Purchase payments for Class D shares are fully invested at the net
asset value next determined after acceptance of the trade. All
purchase orders received by the Distributor from your financial
service firm prior to the close of regular trading (normally 4:00
p.m., Eastern time) on the New York Stock Exchange (the "Ex-
change"), on a regular business day, are processed at that day's
offering price. In addition, orders received by the Distributor
from financial service firms after the offering price is deter-
mined that day will receive such offering price if the orders were
received by the firm from its customer prior to such determination
and were transmitted to and received by the Distributor prior to
its close of business that day (normally 7:00 p.m., Eastern time).
Purchase orders received on other than a regular business day will
be executed on the next succeeding regular business day.
The Distributor, in its sole discretion, may accept or reject
any order for purchase of Fund shares. The sale of shares will be
suspended during any period in which the Exchange is closed for
other than weekends or holidays, or if
April 8, 1998 Prospectus 27
<PAGE>
permitted by the rules of the Securities and Exchange Commission,
when trading on the Exchange is restricted or during an emergency
which makes it impracticable for the Funds to dispose of their se-
curities or to determine fairly the value of their net assets, or
during any other period as permitted by the Securities and Ex-
change Commission for the protection of investors.
Class D shares of the Funds will be held in your account with
your financial service firm and, generally, your firm will hold
your Class D shares in nominee or street name as your agent. Ac-
cordingly, in most cases, the Trust's transfer agent will have no
information with respect to or control over accounts of specific
Class D shareholders and you may obtain information about your ac-
counts only through your financial service firm. In certain cir-
cumstances, your firm may arrange to have your shares held in your
own name or you may subsequently become a holder of record for
some other reason (for instance, if you terminate your relation-
ship with your firm). In such circumstances, please contact the
Distributor at 888-87-PIMCO for information about your account. If
you wish to invest in the Funds through your own account with the
Trust or the Distributor, please inquire as to the other classes
of shares of the Funds. See "Description of the Trust--Multiple
Classes of Shares." In the interest of economy and convenience,
certificates for Class D shares will not be issued.
FINANCIAL Broker-dealers, registered investment advisors and other financial
SERVICE service firms provide varying investment products, programs or ac-
FIRMS counts, pursuant to arrangements with the Distributor, through
which their clients may purchase and redeem Class D shares of the
Funds. Firms will generally provide or arrange for the provision
of some or all of the shareholder servicing and account mainte-
nance services required by your account, including, without limi-
tation, transfers of registration and dividend payee changes; and
may perform functions such as generation of confirmation state-
ments and disbursement of cash dividends. Firms may also arrange
with their clients for other investment or administrative servic-
es. Your firm may independently establish and charge you transac-
tion fees and/or other additional amounts for such services, which
charges could reduce your investment returns on Class D shares of
the Funds.
Your financial service firm may have omnibus accounts and simi-
lar arrangements with the Trust and may be paid for providing sub-
transfer agency and other services. A firm may be paid for its
services directly or indirectly by the Funds, the Advisor or an
affiliate (normally not to exceed an annual rate of 0.35% of a
Fund's average daily net assets attributable to its Class D shares
and purchased through such firm for its clients). Your firm may
establish various minimum investment requirements for Class D
shares of the Funds and may also establish certain privileges with
respect to purchases, redemptions and exchanges of Class D shares
or the reinvestment of dividends.
This Prospectus should be read in connection with your firm's
materials regarding its fees and services.
Exchange Privilege
A shareholder may exchange Class D shares of any Fund for Class D
shares of any other Fund in an account with identical registration
on the basis of their respective net asset values. Class D shares
of each Fund may also be exchanged for Class D shares of certain
series of PIMCO Funds: Multi-Manager Series, an affiliated mutual
fund family composed primarily of stock portfolios managed by
subsidiaries of PIMCO Advisors L.P., an affiliate of the Advisor.
There are currently no exchange fees or charges imposed by the
Trust, although your financial service firm may impose various
fees and charges, investment minimums and other requirements with
respect to exchanges. Please contact your financial service firm
for details. An exchange will constitute a taxable sale for
federal income tax purposes.
The Trust reserves the right to refuse exchange purchases if,
in the judgment of the Advisor, the purchase would adversely af-
fect a Fund and its shareholders. In particular, a pattern of ex-
changes characteristic of "market-timing" strategies may be deemed
by the Advisor to be detrimental to the Trust or a particular
Fund. Although the Trust has no current intention of terminating
or modifying the exchange privilege, it reserves the right to do
so at any time. Except as otherwise permitted by Securities and
Exchange Commission regulations, the Trust will give 60 days' ad-
vance notice to your financial service firm of any termination or
material modification of the exchange privilege. For further in-
formation about exchange privileges, please contact your financial
service firm.

How to Redeem
Class D shares may be redeemed through your financial service firm
on any day the Exchange is open. Shares are redeemed at their net
asset value next determined after a proper redemption request has
been received from your financial service firm. There is no charge
by the Trust or the Distributor with respect to a redemption, al-
though your financial service firm may charge you for its services
in processing your redemption request. Please contact your finan-
cial service firm for details. If you are the holder of record of
your Class D shares, you may contact the Distributor at 888-87-
PIMCO for information regarding how to redeem your shares directly
from the Trust.
Your financial service firm is obligated to transmit your re-
demption orders to the Distributor promptly and is responsible for
ensuring that your redemption request is in proper form. Requests
for redemption received by financial service firms prior to the
close of regular trading (normally 4:00 p.m., Eastern time) on the
Exchange on a regular business day and received by the Distributor
prior to the close of the Distributor's business day will be con-
firmed at the net asset value effective as of the closing of the
Exchange on that day. Your financial service firm will be respon-
sible for furnishing all necessary documentation to the Distribu-
tor or the Trust's transfer agent and may charge you for its serv-
ices. Redemption proceeds will be forwarded to your financial
service firm as promptly as possible and in any event within seven
days after the redemption request is received by the Distributor
in good order. Under unusual circumstances, the Trust may suspend
redemptions or postpone payment for more than seven days, as per-
mitted by federal securities law.
Distributor
The Distributor, a wholly owned subsidiary of PIMCO Advisors L.P.,
is the principal underwriter of the Trust's shares. Pursuant to a
Distribution Contract with the Trust, with respect to each Fund's
Class D shares, the Distributor bears various promotional and
sales related expenses, including the cost of printing and mailing
prospectuses to persons other than current shareholders. The Dis-
tributor, located at 2187 Atlantic Street, Stamford, Connecticut
06902, is a broker-dealer registered with the SEC.
How Net Asset Value Is Determined
The net asset value per share of Class D shares of each Fund will
be determined once on each day on which the Exchange is open as of
the close of regular trading (normally 4:00 p.m., Eastern time) on
the Exchange by dividing the total market value of a Fund's port-
folio investments and other assets attributable to that class,
less any liabilities, by the number of total outstanding shares of
that class. Net asset value will not be determined on days on
which the Exchange is closed.
For all Funds, portfolio securities and other assets for which
market quotations are readily available are stated at market. Mar-
ket value is determined on the basis of last reported sales pric-
es, or if no sales are reported, as is the case for most securi-
ties traded over-the-counter, at the mean between representative
bid and asked quotations obtained from a quotation reporting sys-
tem 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 quotations obtained from brokers
and dealers or pricing services, which take into account appropri-
ate factors such as institutional-sized trading in similar groups
of securities, yield, quality, coupon rate, maturity, type of is-
sue, trading characteristics, and other market data.
Quotations of foreign securities in foreign currency are con-
verted to U.S. dollar equivalents using foreign exchange quota-
tions 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
April 8, 1998 Prospectus 29
<PAGE>
established by the Board of Trustees, with reference to fixed in-
come 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.
Each Fund's liabilities are allocated among its classes. The
total of such liabilities allocated to a class plus that class's
distribution and/or servicing fees and any other expenses spe-
cially allocated to that class are then deducted from the class's
proportionate interest in the Fund's assets, and the resulting
amount for each class is divided by the number of shares of that
class outstanding to produce the class's "net asset value" per
share. Generally, for Funds that pay income dividends, those divi-
dends are expected to differ over time by approximately the amount
of the expense accrual differential between a particular Fund's
classes.
Distributions
Each Fund pays out as dividends substantially all of its net in-
vestment income (which comes from dividends and interest it re-
ceives or is deemed to receive from its investments) and net real-
ized short-term capital gains. For these purposes and for federal
income tax purposes, a portion of the premiums from certain ex-
pired call or put options written by the Fund, net gains from
closing purchase and sale transactions with respect to such op-
tions, and net gains from futures transactions are treated as
short-term capital gains. Each Fund distributes substantially all
of its net realized capital gains, if any, after giving effect to
any available capital loss carry-over.
Shares begin earning dividends on the day after the date that
funds are received by the Trust for the purchase of shares. For
the Fixed Income Funds, dividends are declared daily from net in-
vestment income to shareholders of record at the close of the pre-
vious business day, and distributed to shareholders monthly. The
StocksPLUS and Strategic Balanced 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. There are no sales
charges on reinvested dividends. If a shareholder has elected to
receive dividends and/or capital gain distributions in cash and
the postal or other delivery service is unable to
deliver checks to the shareholder's address of record, such share-
holder's distributions will automatically be invested in the Money

which you may elect to invest dividends and/or distributions paid
by any Fund in shares of the same class of any other Fund of the
Trust at net asset value. Please contact your financial service
firm for details.
Taxes
Each Fund intends to qualify as a regulated investment company an-
nually and to elect to be treated as a regulated investment com-
pany under the Code. As such, a Fund generally will not pay fed-
eral income tax on the income and gains it pays as dividends to
its shareholders. In order to avoid a 4% federal excise tax, each
Fund intends to distribute each year substantially all of its net
income and gains.
Shareholders subject to U.S. federal income tax will be subject
to tax on dividends received from a Fund, regardless of whether
received in cash or reinvested in additional shares. Distributions
received by tax-exempt shareholders generally will not be subject
to federal income tax to the extent permitted under applicable tax
law. All shareholders must treat dividends, other than capital
gain dividends or dividends that represent a return of capital to
shareholders, as ordinary income.

Dividends designated by a Fund as capital gain dividends de-
rived from the Fund's net capital gain (that is, the excess of net
long-term gain over net short-term loss) are taxable to sharehold-
ers as long-term capital gain except as provided by an applicable
tax exemption. Under the Taxpayer Relief Act of 1997, long-term
capital gains will generally be taxed at a 28% or 20% rate, de-
pending upon the holding period of the portfolio securities. Any
distributions that are not from a Fund's net investment income,
short-term capital gain, or net capital gain may be characterized
as a return of capital to shareholders or, in some cases, as capi-
tal gain. Certain dividends declared in October, November or De-
cember of a calendar year are taxable to shareholders (who other-
wise are subject to tax on dividends) as though received on Decem-
ber 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 distribu-
tions 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.
Dividends paid to shareholders by the Municipal Bond Fund which
are derived from interest on Municipal Bonds are expected to be
designated by the Fund as "exempt-interest dividends," and share-
holders may generally exclude such dividends from gross income for
federal income tax purposes. However, if a shareholder receives
social security or railroad retirement benefits, the shareholder
may be taxed on a portion of those benefits as a result of receiv-
ing tax- exempt income. In addition, certain exempt-interest divi-
dends could, as discussed below, cause certain shareholders to be-
come subject to the alternative minimum tax and may increase the
alternative minimum tax liability of shareholders already subject
to this tax.
To the extent that dividends paid to shareholders by the Munic-
ipal Bond Fund are derived from taxable interest or from capital
gains, such dividends will be subject to federal income tax. Any
gain realized on a redemption of shares will be taxable gain, sub-
ject to any applicable tax exemption for which an investor may
qualify.
Dividends derived from interest on certain U.S. Government se-
curities may be exempt from state and local taxes, although inter-
est on mortgage-backed U.S. Government securities is generally not
so exempt. The distributions of "exempt-interest dividends" paid
by the Municipal Bond Fund may be exempt from state and local tax-
ation when received by a shareholder to the extent that they are
derived from interest on Municipal Bonds issued by the state or
political subdivision in which such shareholder resides. The fed-
eral exemption for "exempt-interest dividends" attributable to Mu-
nicipal Bonds does not necessarily result in exemption of such
dividends from income for the purpose of state and local taxes.
The Trust will report annually on a state-by-state basis the
source of income the Municipal Bond Fund receives on Municipal
Bonds that was paid out as dividends during the preceding year.
The Code also provides that exempt-interest dividends allocable
to interest received from "private activity bonds" issued after
August 7, 1986 are an item of tax preference for individual and
corporate alternative minimum tax at the applicable rate for indi-
viduals and corporations. Therefore, if the Municipal Bond Fund
invests in such private activity bonds, certain of its sharehold-
ers may become subject to the alternative minimum tax on that part
of its distributions to them that are derived from interest income
on such bonds, and certain shareholders already subject to such
tax may have increased liability therefor. However, it is the
present policy of the Municipal Bond Fund to invest no more than
20% of its assets in such bonds. Other provisions of the Code af-
fect the tax treatment of distributions from the Municipal Bond
Fund for corporations, casualty insurance companies, and financial
institutions. In particular, under the Code, for corporations, al-
ternative minimum taxable income will be increased by a percentage
of the amount by which the corporation's "adjusted current earn-
ings" (which includes various items of tax exempt income) exceeds
the amount otherwise determined to be alternative minimum taxable
income. Accordingly, an investment in the Municipal Bond Fund may
cause shareholders to be subject to (or result in an increased li-
ability under) the alternative minimum tax.
Dividends to shareholders of the Municipal Bond Fund derived
from money market instruments and U.S. Government securities are
generally taxable as ordinary income. The Fund may seek to reduce
fluctuations in its net asset value by engaging in portfolio
strategies involving options on securities, futures contracts, and
options on futures contracts. Any gain derived by the Fund from
the use of such instruments, including by reason of "marking to
market," will be treated as a combination of short-term and long-
term capital gain and, if not offset by realized capital losses
incurred by
April 8, 1998 Prospectus 31
<PAGE>
the Fund, will be distributed to shareholders (possibly requiring
the liquidation of other portfolio securities) and will be taxable
to shareholders as a combination of ordinary income and long-term
capital gain.
Interest accrued by a Fund from inflation-indexed bonds will be
includable in the Fund's gross income in the period in which they
accrue. Periodic adjustments for inflation in the principal value
of these securities also may give rise to original issue discount,
which, likewise, will be includable in the Fund's gross income on
a current basis, regardless of whether the Fund receives any cash
payments. See "Taxation--Original Issue Discount" in the Statement
of Additional Information. Amounts includable in a Fund's gross
income become subject to tax-related distribution requirements.
Accordingly, a Fund may be required to make annual distributions
to shareholders in excess of the cash received in a given period
from these investments. As a result, the Fund may be required to
liquidate certain investments at a time when it is not advanta-
geous to do so. If the principal value of an inflation-indexed
bond is adjusted downward in any period as a result of deflation,
the reduction may be treated as a loss to the extent the reduction
exceeds coupon payments received in that period; in that case, the
amount distributable by the Fund may be reduced and amounts dis-
tributed previously in the taxable year may be characterized in
some circumstances as a return of capital.
Taxable shareholders should note that the timing of their in-
vestment could have undesirable tax consequences. If shares are
purchased on or just before the record date of a dividend, taxable
shareholders will pay full price for the shares and may receive a
portion of their investment back as a taxable distribution.
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.

FUND Pacific Investment Management also serves as administrator to the
ADMINISTRA- Funds' Class D shares pursuant to an administration agreement with
TOR the Trust. Pacific Investment Management provides administrative
services for Class D shareholders of the Funds, which include
clerical help and accounting, bookkeeping, internal audit servic-
es, and certain other services required by the Funds, preparation
of reports to the Funds' shareholders and regulatory filings. Pa-
cific Investment Management may also retain certain of its affili-
ates to provide certain of these services. In addition, Pacific
Investment Management, at its own expense, arranges for the provi-
sion of legal, audit, custody, transfer agency (including sub-
transfer agency and other administrative services) and other serv-
ices for the Funds, and is responsible for the costs of registra-
tion of the Trust's shares and the printing of prospectuses and
shareholder reports for current shareholders.
Pacific Investment Management or an affiliate may pay financial
service firms a portion of the Class D administration fees in re-
turn for the firms' services (normally not to exceed an annual
rate of .35% of a Fund's average daily net assets attributable to
Class D shares purchased through such firms). The Funds' adminis-
tration agreement includes a plan for Class D shares that has been
adopted in conformity with the requirements set forth under Rule
12b-1 of the 1940 Act to allow for the payment of up to .25% per
annum of the Class D administrative fees for activities that may
be deemed to be primarily intended to result in the sale of Class
D shares. The principal types of activities for which such pay-
ments may be made are services in connection with the distribution
of Class D shares and/or the provision of shareholder services.
The Funds (and not Pacific Investment Management) are responsi-
ble for the following expenses: (i) salaries and other compensa-
tion of any of the Trust's executive officers and employees who
are not officers, directors, stockholders or employees of Pacific
Investment Management or its subsidiaries or affiliates; (ii)
taxes and governmental fees; (iii) brokerage fees and commissions
and other portfolio transaction expenses; (iv) the costs of bor-
rowing money, including interest expenses; (v) fees and expenses
of the Trustees who are not "interested persons" of Pacific In-
vestment Management or the

Trust, and any counsel retained exclusively for their benefit;
(vi) extraordinary expenses, including costs of litigation and in-
demnification expenses; (vii) expenses, such as organizational ex-
penses, which are capitalized in accordance with generally ac-
cepted accounting principles; and (viii) any expenses allocated or
allocable to a specific class of shares, which include servicing
fees payable with respect to Class D shares, and may include cer-
tain other expenses as permitted by the Trust's Multi-Class Plan
adopted pursuant to Rule 18f-3 under the 1940 Act, subject to re-
view and approval by the Trustees.
ADVISORY The Funds feature fixed advisory and administrative fee rates. For

Both the investment advisory contract and administration agree-
ment with respect to Class D shares of the Funds may be terminated
by the Trustees at any time on 60 days' written notice. The in-
vestment advisory contract may be terminated by Pacific Investment
Management on 60 days' written notice. Following the expiration of
the one-year period commencing with the effectiveness of the ad-
ministration agreement, it may be terminated by Pacific Investment
Management on 60 days' written notice. Following its initial two-
year term, the investment advisory contract will continue from
year to year if approved by the Trustees. Following its initial
one-year term, the administration agreement with respect to Class
D shares of the Funds will continue from year-to-year if approved
by the Trustees.
PORTFOLIO Pursuant to the advisory contract, the Advisor places orders for
TRANS- the purchase and sale of portfolio investments for the Funds' ac-
ACTIONS counts 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 Advisor will seek the best price and ex-
ecution of the Funds' orders. In doing so, a Fund may pay higher
commission rates than the lowest available when the Advisor be-
lieves it is reasonable to do so in light of the value of the bro-
kerage and research services provided by the broker effecting the
transaction.
The Advisor manages the Funds without regard generally to re-
strictions on portfolio turnover, except those imposed on its
ability to engage in short-term trading by provisions of the fed-
eral tax laws. The use of certain derivative instruments with rel-
atively short maturities may tend to exaggerate the portfolio
turnover rate for some of the Funds. Trading in fixed income secu-
rities does not generally involve the payment of brokerage commis-
sions, 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. The portfolio turnover rate for
each Fund for which financial highlights are provided in this Pro-
spectus is set forth under "Financial Highlights."
Some securities considered for investments by the Funds may
also be appropriate for other clients served by the Advisor. If a
purchase or sale of securities consistent with the investment pol-
icies of a Fund and one or more of these
34 PIMCO Funds: Pacific Investment Management Series
<PAGE>
clients served by the Advisor 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 Ad-
visor. The Advisor may aggregate orders for the Funds with simul-
taneous transactions entered into on behalf of other clients of
the Advisor so long as price and transaction expenses are averaged
either for that transaction or for the day.
Description of the Trust
CAPITALIZA- The Trust was organized as a Massachusetts business trust on Feb-
TION ruary 19, 1987. The Board of Trustees may establish additional
portfolios 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 cir-
cumstances, 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 also pro-
vides for indemnification out of Trust property for all loss and
expense of any shareholder held personally liable for the obliga-
tions of the Trust. The risk of a shareholder incurring financial
loss on account of shareholder liability is limited to circum-
stances in which such disclaimer is inoperative or the Trust it-
self is unable to meet its obligations, and thus should be consid-
ered remote.
MULTIPLE In addition to Class D shares, each Fund also offers up to five
CLASSES OF additional classes of shares, Class A, Class B, Class C, Institu-
SHARES tional Class and Administrative Class shares, through separate
prospectuses. The other classes are subject to different sales
charges and expense levels than Class D shares, which will affect
performance accordingly. This Prospectus relates only to the Class
D shares of the Funds. Unlike Class D shares, which may be pur-
chased only through financial service firms, the other classes may
be purchased directly from the Trust and/or the Distributor.
Shareholders of a particular class may also receive additional
services or services different from those received by the other
classes. To obtain more information about the other classes of
shares, please call the Distributor at 800-927-4648 (for Institu-
tional and Administrative Classes) or 800-426-0107 (for Class A,
Class B or Class C).
VOTING Shareholders have the right to vote on the election of Trustees
and on any and all matters on which the law or the Declaration of
Trust states they may be entitled to vote. The Trust is not re-
quired to hold regular annual meetings of Trust shareholders and
does not intend to do so. Shareholders of a class of shares or
Fund have separate voting rights with respect to matters that only
affect that class or Fund. 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 pro-
portionate voting for fractional shares). As of February 28, 1998,
the following were shareholders of record of at least 25% of the
outstanding voting securities of the indicated Fund: National Fi-
nancial Services Corporation (New York, New York) with respect to
the Real Return Bond Fund; Pacific Investment Management Company
(Newport Beach, California) with respect to the Total Return Mort-
gage and Municipal Bond Funds; and California Community Foundation
(Los Angeles, California) with respect to the Strategic Balanced
Fund. To the extent such shareholders are also the beneficial own-
ers of those shares, they may be deemed to control (as that term
is defined in the 1940 Act) the relevant 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).

Appendix A
Description of Duration
Duration is a measure of the expected life of a fixed income secu-
rity that was developed as a more precise alternative to the con-
cept of "term to maturity." 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 securi-
ty). However, "term to maturity" measures only the time until a
fixed income security provides its final payment, taking no ac-
count of the pattern of the security's payments prior to maturity.
In contrast, duration incorporates a bond's yield, coupon interest
payments, final maturity and call features into one measure. Dura-
tion management is one of the fundamental tools used by the Advi-
sor.
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 occur-
ring prior to the payment of principal, duration is always less
than maturity. In general, all other things being equal, the lower
the stated or 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 dura-
tion by approximately the same amount that selling an equivalent
amount of the underlying securities would.
There are some situations where even the standard duration cal-
culation 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 inter-
est rate exposure corresponds to the frequency of the coupon re-
set. For inflation-indexed bonds, duration is calculated on the
basis of modified real duration, which measures price changes of
inflation-indexed bonds on the basis of changes in real, rather
than nominal, interest rates. 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. Finally, the duration of a fixed income security
may vary over time in response to changes in interest rates and
other market factors. In these and other similar situations, the
Advisor will use more sophisticated analytical techniques that in-
corporate the anticipated economic life of a security into the de-
termination of its interest rate exposure.

Appendix B
Description of Securities Ratings
Certain of the Funds make use of average portfolio credit quality
standards to assist institutional investors whose own investment
guidelines limit their investments accordingly. In determining a
Fund's overall dollar-weighted average quality, unrated securities
are treated as if rated, based on the Advisor's view of their com-
parability to rated securities. A Fund's use of average quality
criteria is intended to be a guide for those institutional invest-
ors 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 in-
vestments 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 Advisor to be of comparable quality).
The percentage of a Fund's assets invested in securities in a par-
ticular rating category will vary. Following is a description of
Moody's and S&P's ratings applicable to fixed income securities.
MOODY'S CORPORATE AND MUNICIPAL BOND RATINGS
INVESTORS Aaa: Bonds which are rated Aaa are judged to be of the best
SERVICE, quality. They carry the smallest degree of investment risk and are
INC. generally referred to as "gilt edge." Interest payments are pro-
tected by a large or by an exceptionally stable margin and princi-
pal is secure. While the various protective elements are likely to
change, such changes as can be visualized are most unlikely to im-
pair the fundamentally strong position of such issues.
Aa: Bonds which are rated Aa are judged to be of high quality
by all standards. Together with the Aaa group they comprise what
are generally known as high-grade bonds. They are rated lower than
the best bonds because margins of protection may not be as large
as in Aaa securities or fluctuation of protective elements may be
of greater amplitude or there may be other elements present that
make the long-term risks appear somewhat larger than with Aaa se-
curities.
A: Bonds which are rated A possess many favorable investment
attributes and are to be considered as upper-medium-grade obliga-
tions. Factors giving security to principal and interest are con-
sidered adequate but elements may be present that suggest a sus-
ceptibility to impairment sometime in the future.
Baa: Bonds which are rated Baa are considered as medium-grade
obligations (i.e., they are neither highly protected nor poorly
secured). Interest payments and principal security appear adequate
for the present but certain protective elements may be lacking or
may be characteristically unreliable over any great length of
time. Such bonds lack outstanding investment characteristics and
in fact have speculative characteristics as well.
Ba: Bonds which are rated Ba are judged to have speculative el-
ements; their future cannot be considered as well-assured. Often
the protection of interest and principal payments may be very mod-
erate and thereby not well safeguarded during both good and bad
times over the future. Uncertainty of position characterizes bonds
in this class.
B: Bonds which are rated B generally lack characteristics of a
desirable investment. Assurance of interest and principal payments
or of maintenance of other terms of the contract over any long pe-
riod of time may be small.
Caa: Bonds which are rated Caa are of poor standing. Such is-
sues may be in default or there may be present elements of danger
with respect to principal or interest.
Ca: Bonds which are rated Ca represent obligations which are
speculative in a high degree. Such issues are often in default or
have other marked shortcomings.
C: Bonds which are rated C are the lowest rated class of bonds
and issues so rated can be regarded as having extremely poor pros-
pects of ever attaining any real investment standing.
Moody's applies numerical modifiers, 1, 2, and 3 in each ge-
neric 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 in-
dicates 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 is-
suers 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 indem-
nity are excluded unless explicitly rated.
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 em-
ployed; conservative capitalization structure with moderate reli-
ance on debt and ample asset protection; broad margins in earnings
coverage of fixed financial charges and high internal cash genera-
tion; 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 ob-
ligations. This will normally be evidenced by many of the charac-
teristics 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 ob-
ligations. The effect of industry characteristics and market com-
positions may be more pronounced. Variability in earnings and
profitability may result in changes in the level of debt protec-
tion measurements and may require relatively high financial lever-
age. Adequate alternate liquidity is maintained.
NOT PRIME: Issuers rated Not Prime do not fall within any of
the Prime rating categories.
STANDARD & CORPORATE AND MUNICIPAL BOND RATINGS
POOR'S
RATINGS INVESTMENT GRADE
SERVICES AAA: Debt rated AAA has the highest rating assigned by S&P. Ca-
pacity 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 ca-
pacity to pay interest and repay principal for debt in this cate-
gory than in higher-rated categories.
SPECULATIVE GRADE
Debt rated BB, B, CCC, CC, and C is regarded as having predomi-
nantly speculative characteristics with respect to capacity to pay
interest and repay principal. BB indicates the least degree of
speculation and C the highest. While such debt will likely have
some quality and protective characteristics, these are outweighed
by large uncertainties or major exposures to adverse conditions.
BB: Debt rated BB has less near-term vulnerability to default
than other speculative issues. However, it faces major ongoing un-
certainties or exposure to adverse business, financial, or eco-
nomic 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.
B: Debt rated B has a greater vulnerability to default but cur-
rently 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 ac-
tual 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 re-
payment 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 ac-
tual 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 rat-
ing. The C rating may be used to cover a situation where a bank-
ruptcy petition has been filed, but debt service payments are con-
tinued.
CI: The rating CI is reserved for income bonds on which no in-
terest 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 modi-
fied 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 com-
pletion 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 com-
pletion. The investor should exercise his own judgment with re-
spect 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.
The absence of an "r" symbol should not be taken as an indica-
tion that an obligation will exhibit no volatility or variability
in total return.
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
An S&P 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 catego-
ries, 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.
A-2: Capacity for timely payment on issues with this designa-
tion 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 ad-
verse effects of changes in circumstances than obligations carry-
ing the higher designations.

B: Issues rated B are regarded as having only speculative ca-
pacity 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,
sell or hold a security inasmuch as it does not comment as to mar-
ket price or suitability for a particular investor. The ratings
are based on current information furnished to S&P by the issuer or
obtained from other sources it considers reliable. S&P does not
perform an audit in connection with any rating and may, on occa-
sion, rely on unaudited financial information. The ratings may be
changed, suspended, or withdrawn as a result of changes in or un-
availability of such information.
