                              CERTAIN RISK FACTORS
- --------------------------------------------------------------------------------

         In addition to the typical risks of investing in securities, and in
fixed income securities in particular (as well as equity securities for the
Western Asset Enhanced Equity Portfolio), the Portfolios may be subject to
certain special risks. These risks include the risks associated with investing
in: foreign markets and the securities of foreign issuers (these risks increase
to the extent a Portfolio invests in emerging markets); derivative securities
(which tend to be more volatile than the underlying security); and lower rated
securities (high yield or junk bonds). See "Description of Each Portfolio and
Its Investment Strategy" and "Common Investment Policies and Techniques; Risk
Factors" for more information about which Portfolios are likely to be subject to
the foregoing risks and a description of other risks to which the Portfolios are
subject.

                               PURCHASE OF SHARES
- --------------------------------------------------------------------------------

         The Portfolios offer two classes of shares:  Institutional Class and
Financial Intermediary Class.  Shares in the Financial Intermediary Class bear a
12b-1 fee.  See "Distribution Plans" below for more information.  The minimum
initial investment is $1 million, subject to certain exceptions.  See "Purchase
of Shares."

                           REDEMPTIONS AND EXCHANGES
- --------------------------------------------------------------------------------

         Shares of each Portfolio may be redeemed without cost at the relevant
net asset value per share next determined after receipt of the redemption
request. The redemption price may be more or less than the purchase price. See
"Redemption of Shares." Shares of any Portfolio may be exchanged on the basis of
relative net asset values for shares of the same class of any other Portfolio or
of any portfolio of LM Institutional Fund Advisors II, Inc. See "Exchange
Privilege."

                          DIVIDENDS AND DISTRIBUTIONS
- --------------------------------------------------------------------------------

         The Western Asset Government Money Market Portfolio and the Western
Asset Money Market Portfolio declare dividends daily (out of their net
investment income for that day) and pay dividends monthly. Each of the other
Portfolios declares and pays dividends quarterly out of its net investment
income for that quarter. Distributions of net realized capital gains are made
annually. All dividends and distributions will be reinvested automatically at
net asset value in additional shares of the same class of the same Portfolio,
unless cash payment is requested. See "Dividends and Distributions to
Shareholders."

EXPENSE INFORMATION
- --------------------------------------------------------------------------------

         Expenses are one of several factors to consider when investing. The
following tables contain annualized expense information about the Portfolios
based on the most recent nine month fiscal period (in the case of the Western
Asset Limited Duration Portfolio, the Western Asset Intermediate Portfolio and
the Western Asset Core Portfolio) or amounts expected to be incurred in the
current fiscal year (in the case of the other Portfolios). Information for the
Western Asset Limited Duration Portfolio, the Western Asset Intermediate and the
Western Asset Core Portfolio has been restated to give effect to revised
investment advisory and administration arrangements recently approved by
shareholders. The examples show the cumulative expenses attributable to a
hypothetical $1,000 investment over specified periods, assuming 5% annual return
and redemption at the end of each period. The paragraph following the tables and
examples contains additional information about the tables, the examples and the
Portfolios' expenses.

        The tables are provided to help you understand the expenses of investing
in a Portfolio and your share of the Portfolio's operating expenses. The
management fees shown in the table for each Portfolio reflect voluntary expense
limitations currently in effect, which are expected to continue through the
current fiscal year. The following table shows what management fees and total
operating expenses would be for each of the Portfolios in the absence of the
expense limitations. The information in the table for the Western Asset Limited
Duration Portfolio, the Western Asset Intermediate Portfolio and the Western
Asset Core Portfolio has been annualized and has been restated to give effect to
revised investment advisory and administration arrangements, the net effect of
which was to increase the contractual rate of the management fee by 0.05% on an
annual basis and eliminate administratives fees.

         "Other expenses" are based on estimated amounts for the current fiscal
year in the case of each of the Portfolios other than the Western Asset Limited
Duration Portfolio, the Western Asset Intermediate Portfolio and the Western
Asset Core Portfolio, which are based on the most recent nine month period. THE
EXAMPLES DO NOT REPRESENT PAST OR FUTURE EXPENSE LEVELS. ACTUAL EXPENSES MAY BE
GREATER OR LESS THAN THOSE SHOWN. Federal regulations require the examples to
assume a 5% annual return, but actual annual returns will vary. As a result of
Rule 12b-1 fees, long-term shareholders of the Financial Intermediary Class may
pay more than the economic equivalent of the maximum sales charge permitted by
the National Association of Securities Dealers.

DESCRIPTION OF EACH PORTFOLIO AND ITS
INVESTMENT STRATEGY
- -------------------------------------------------------------------------------

         The investment objective and policies for each Portfolio are stated
below. The Portfolios are not intended to be a complete investment program, and
there is no assurance that any Portfolio will achieve its investment objective.
Please see "Common Investment Policies and Techniques; Risk Factors" below and
the SAI for additional information concerning the Portfolios' investment
programs and the risks associated with investing in the Portfolios. Each of the
Portfolios may from time to time depart from the policies described below for
temporary "defensive" purposes. See "Common Investment Policies and Techniques;
Risk Factors -- Alternative Investment Strategies" for more information.


                WESTERN ASSET GOVERNMENT MONEY MARKET PORTFOLIO

- --------------------------------------------------------------------------------
Adviser:     Western Asset
- --------------------------------------------------------------------------------
Objective:   obtain high current income consistent with liquidity and
             conservation of principal
- --------------------------------------------------------------------------------

         The Portfolio invests only in U.S. Government obligations, repurchase
agreements with respect to such instruments and debt obligations of
"supranational organizations" as described below. U.S. Government obligations
include: (1) U.S. Treasury obligations, which differ only in their interest
rates, maturities and times of issuance, and (2) obligations issued or
guaranteed by U.S. Government agencies and instrumentalities which are supported
by any of the following: (a) the full faith and credit of the U.S. Government
(such as certificates of the Governmental National Mortgage Association
("GNMA")), (b) the right of the issuer to borrow an amount limited to a specific
line of credit from the U.S. Government (such as obligations of the Federal Home
Loan Banks), (c) the discretionary authority of the U.S. Government to purchase
certain obligations of an agency or instrumentality (such as securities issued
by Fannie Mae ("FNMA"), formerly the Federal National Mortgage Association) or
(d) only the credit of the instrumentality (such as the securities issued by
Freddie Mac (formerly the Federal Home Loan Mortgage Corporation)). In the case
of obligations not backed by the full faith and credit of the U.S. Government,
the Portfolio must look to the agency or instrumentality issuing or guaranteeing
the obligation for ultimate repayment and may not be able to assert a claim
against the United States itself in the event the agency or instrumentality does
not meet its commitments. The U.S. Government does not insure or guarantee the
market value of the Portfolio's shares.

         Although the Portfolio attempts to maintain a stable net asset value of
$1.00 per share, the Portfolio, of course, cannot guarantee a net asset value of
$1.00 per share. In an

                                      -18-



<PAGE>



attempt to maintain a stable net asset value per share, the Portfolio pursues
several practices intended to minimize the effect of interest rate fluctuations.
The Portfolio will not purchase instruments having a remaining term to maturity
of more than 397 days, will maintain an average maturity, computed on a
dollar-weighted basis, of 90 days or less, and will buy only high quality
securities which Western Asset believes present minimal credit risk. The
Portfolio may invest in variable and floating rate obligations that have stated
maturities in excess of 397 days if such obligations comply with conditions
established by the SEC. Securities held by the Portfolio as collateral for
repurchase agreements and other collateralized transactions may have remaining
maturities in excess of 397 days.

         The Portfolio also may invest in fixed income securities issued by
"supranational organizations," which are entities designated or supported by a
government or governmental entity to promote economic development, and include,
among others, the Asian Development Bank, the European Community, the European
Investment Bank, the Inter-American Development Bank, the International Monetary
Fund, the United Nations, the International Bank for Reconstruction and
Development ("World Bank") and the European Bank for Reconstruction and
Development. These organizations have no taxing authority and are dependent upon
their members for payments of interest and principal. Moreover, the lending
activities of such supranational entities may be limited to a percentage of
their total capital (including "callable capital" contributed by members at an
entity's call), reserves and net income.

         The Portfolio may purchase or sell securities on a forward commitment
basis. To the extent permitted by applicable law, the Portfolio may also engage
in reverse repurchase agreements and other borrowings. See "Common Investment
Policies and Techniques; Risk Factors" below.

instruments of domestic and foreign banks and savings and loan institutions
(such as certificates of deposit, demand and time deposits, savings shares and
bankers' acceptances), provided that the issuing bank or institution has total
assets of over $1 billion at the time of purchase or the principal amount of the
instrument is insured by the Federal Deposit Insurance Corporation; and
commercial paper and other short-term investments. The Portfolio may also invest
in repurchase

                                      -19-

agreements involving any of the foregoing instruments. A money market instrument
is considered to be "high quality" if it has received one of the two highest
ratings by two or more Nationally Recognized Statistical Rating Organizations
("NRSROs") (or by one NRSRO if only one has rated the security) or, if unrated,
is determined by Western Asset to be of comparable quality.

         Although the Portfolio attempts to maintain a stable net asset value of
$1.00 per share, the Portfolio, of course, cannot guarantee a net asset value of
$1.00 per share. In an attempt to maintain a stable net asset value per share,
the Portfolio pursues several practices intended to minimize the effect of
interest rate fluctuations. The Portfolio will not purchase instruments having a
remaining term to maturity of more than 397 days, and will maintain an average
maturity, computed on a dollar-weighted basis, of 90 days or less. The Portfolio
may invest in variable and floating rate obligations that have stated maturities
in excess of 397 days if such obligations comply with conditions established by
the SEC. Securities held by the Portfolio as collateral for repurchase
agreements and other collateralized transactions may have remaining maturities
in excess of 397 days. The Portfolio may purchase or sell securities on a
forward commitment basis, and will invest only in U.S. dollar-denominated
securities.

         High quality money market instruments can be divided into two
categories: "first tier" securities and "second tier" securities. An instrument
rated in the highest rating category by at least two NRSROs (or one NRSRO if
only one has rated the security) or, if unrated, determined by Western Asset to
be of comparable quality, is a "first tier" security. "Second tier" securities
are all other high quality securities. The Portfolio may not invest more than
five percent of its total assets in first tier securities of any one issuer
(other than the U.S. Government, its agencies or instrumentalities), except on a
temporary basis. The Portfolio may not invest more than one percent of its total
assets, or $1 million, whichever is greater, in the second tier securities of
any one issuer, and may not invest more than five percent of its total assets in
second tier securities generally. Both the percentages and the quality standards
set forth in this paragraph are measured at the time a security is purchased.

         The Portfolio's foreign investments (all of which will be U.S.
dollar-denominated) subject the Portfolio to investment risks different from
those associated with domestic investments. For additional information
concerning these risks, see "Common Investment Policies and Techniques; Risk
Factors -- Foreign Securities" below. To the extent permitted by applicable law,
the Portfolio may also engage in reverse repurchase agreements and other
borrowings. See "Common Investment Policies and Techniques; Risk Factors" below.

                    WESTERN ASSET LIMITED DURATION PORTFOLIO
                      WESTERN ASSET INTERMEDIATE PORTFOLIO
                   WESTERN ASSET INTERMEDIATE PLUS PORTFOLIO
                          WESTERN ASSET CORE PORTFOLIO
                       WESTERN ASSET CORE PLUS PORTFOLIO

- --------------------------------------------------------------------------------
Advisers:   Western Asset (each Portfolio) and WAGM (non-U.S. portion of the
            Western Asset Intermediate Plus and Western Asset Core Plus
            Portfolios)
- --------------------------------------------------------------------------------
Objective:  maximize total return, consistent with prudent investment management
            and liquidity needs, by investing to obtain the average duration
            specified for that Portfolio.  "Total return" includes interest from
            underlying securities, capital gains and appreciation on the
            securities held in the Portfolio, and gains from the sale of futures
            and options.
- --------------------------------------------------------------------------------

         As set forth below, the Portfolios differ from one another primarily in
the range of duration and/or in the proportion of assets invested in certain
types of securities. Further, the Western Asset Intermediate Plus Portfolio and
the Western Asset Core Plus Portfolio (the "Western Asset Plus Portfolios")
differ from the other Portfolios in the percentage of their assets that they may
invest in securities of foreign issuers, in non-U.S. dollar-denominated
securities and in non-investment grade debt securities.

         Duration is a measure of the expected life of a fixed income security
on a cash flow basis. Most debt obligations provide interest payments and a
final payment at maturity. Some also have call provisions that allow the issuer
to redeem the security at specified dates prior to maturity. Duration
incorporates yield, coupon interest payments, final maturity and call features
into a single measure. It is therefore considered a more accurate measure of a
security's expected life and sensitivity to interest rate changes than is the
security's term to maturity. See "Common Investment Policies and Techniques;
Risk Factors" for a further explanation of the term "duration" and its
application to various fixed income securities.

         The Portfolios invest primarily in the following types of securities:
obligations issued or guaranteed by the U.S. Government, its agencies or
instrumentalities; U.S. dollar-denominated fixed income securities of
non-governmental domestic or foreign issuers rated at the time of purchase Baa
or better by Moody's Investors Service ("Moody's") or BBB or better by Standard
& Poor's ("S&P"), securities comparably rated by another NRSRO or, if unrated,
determined by an Adviser to be of comparable quality; mortgage- and other
asset-backed securities; and U.S. dollar-denominated obligations of foreign
governments or their subdivisions, agencies and instrumentalities, international
agencies or supranational organizations. The Portfolios may also invest in other
securities or investments, including certificates of deposit, time deposits and
bankers' acceptances issued

                                      -21-



<PAGE>



by domestic and foreign banks and denominated in U.S. dollars and commercial
paper and other short-term investments, and may engage in repurchase agreements
and reverse repurchase agreements.  See "Common Investment Policies and
Techniques; Risk Factors" for more information.

         Each Portfolio is authorized to invest up to 25% of its total assets in
the securities of foreign issuers. However, each Portfolio, other than the
Western Asset Plus Portfolios, presently intends to limit such investments to
securities denominated in U.S. dollars. Each of the Western Asset Plus
Portfolios may invest up to 20% of its total assets in the non-dollar
denominated securities of foreign issuers. See "Common Investment Policies and
Techniques; Risk Factors -- Foreign Securities" for more information.

         Each Portfolio, other than the Western Asset Plus Portfolios, may
invest up to 5% of its net assets in debt securities that are rated at the time
of purchase below investment grade but rated at least B or higher by an NRSRO
or, if unrated, determined by an Adviser to be of comparable quality. Each of
the Western Asset Plus Portfolios may invest up to 15% of its total assets in
debt securities that are rated at the time of purchase below investment grade
but rated at least B or higher by an NRSRO or, if unrated, determined by an
Adviser to be of comparable quality. See the Appendix to the Prospectus for a
description of Moody's, S&P's and Fitch Investors Service, Inc.'s ratings
applicable to fixed income securities and "Common Investment Policies and
Techniques; Risk Factors -- Debt and Fixed Income Securities -- Lower-Rated
Securities" for more information concerning fixed income securities of below
investment grade quality. If the rating of a security in which a Portfolio has
invested falls below the minimum rating in which the Portfolio is permitted to
invest, the Portfolio will either dispose of that security within a reasonable
time or hold the security for so long as the relevant Adviser determines
appropriate for that Portfolio, having due regard for market conditions, tax
implications and other applicable factors.

         Each Portfolio may buy or sell futures contracts on fixed income
instruments, options on such futures contracts and options on securities to
hedge against changes in the value of securities which the Portfolio owns or
anticipates purchasing due to anticipated changes in interest rates or for
non-hedging purposes. Each Portfolio may also purchase and sell options on debt
securities. See "Common Investment Policies and Techniques -- Options and
Futures."

         Each Portfolio also may purchase preferred stocks, structured notes,
municipal securities, convertible securities, pay-in-kind securities and zero
coupon bonds, may purchase or sell securities on a forward commitment basis,
lend its portfolio securities, and borrow money for temporary or emergency
purposes. See "Common Investment Policies and Techniques; Risk Factors" below
for more information about these practices.

         In selecting securities for each Portfolio, the Advisers may utilize
economic forecasting, interest rate anticipation, credit and call risk analysis,
and other security

                                      -22-



<PAGE>



selection techniques. The proportion of each Portfolio's assets committed to
investment in securities with particular characteristics (such as maturity, type
and coupon rate) will vary based on the Advisers' outlook for the U.S. and
foreign economies, the financial markets and other factors.

         The composition of the Portfolios is as follows:

WESTERN ASSET LIMITED DURATION PORTFOLIO . . .
- --------------------------------------------------------------------------------

invests in a portfolio with a dollar-weighted average duration normally ranging
between one and three years. The total rate of return for this Portfolio is
expected to exhibit less volatility than that of the other Portfolios because
its average duration will be shorter.

WESTERN ASSET INTERMEDIATE PORTFOLIO AND
WESTERN ASSET INTERMEDIATE PLUS PORTFOLIO . . .
- --------------------------------------------------------------------------------

invest in a portfolio with a dollar-weighted average duration normally ranging
between two and four years. The total rate of return for each of these
Portfolios is expected to exhibit less volatility than that of the Western Asset
Core Portfolio or the Western Asset Core Plus Portfolio because its average
duration will be shorter.

WESTERN ASSET CORE PORTFOLIO AND
WESTERN ASSET CORE PLUS PORTFOLIO  . . .
- --------------------------------------------------------------------------------

invest in a portfolio with a dollar-weighted average duration that will normally
stay within (plus/minus) 20% of what Western Asset believes to be the average
duration of the domestic bond market as a whole, but may have a longer or
shorter duration during periods of unusual market conditions, as judged by
Western Asset. Western Asset bases its analysis of the average duration of the
domestic bond market on bond market indices which it believes to be
representative. Western Asset currently uses the Lehman Brothers Aggregate Bond
Index for this purpose. As the average duration of the domestic bond market is
currently about four and one-half years, the duration of these Portfolios is
currently expected to range between four and six years. Portfolio holdings will
be focused in areas of the bond market (based on quality, sector, coupon,
maturity, country or currency) which the relevant Adviser believes to be
relatively undervalued.

         The average duration of any Portfolio may be less than that specified
during periods of unusual liquidity needs or immediately following a major
contribution of cash.

         With respect to the Western Asset Plus Portfolios, Western Asset will
determine the relative portion of a Portfolio's assets that is allocated to
foreign securities (and therefore to the investment discretion of WAGM).

                       WESTERN ASSET HIGH YIELD PORTFOLIO

- --------------------------------------------------------------------------------
Adviser:    Western Asset
- --------------------------------------------------------------------------------
Objective:  maximize total return, consistent with prudent investment
            management. "Total return" includes interest from underlying
            securities, capital gains and appreciation on the securities held in
            the Portfolio, and gains from the sale of futures and options.
- --------------------------------------------------------------------------------

         Under normal market conditions, the Portfolio will invest at least 75%
of its total assets in U.S. dollar-denominated debt or fixed income securities
of non-governmental domestic issuers that are rated below investment grade by
one or more NRSROs or are of a comparable quality as determined by Western
Asset. These securities are commonly known as "junk bonds" or "high yield
bonds." Western Asset expects that, under normal market conditions, all or
substantially all of the Portfolio's assets will be invested in such securities.
Non-investment grade securities and certain investment grade securities have
speculative characteristics and are therefore more volatile. A rating in the
lowest category indicates that the security is highly speculative and may be in
default or in danger of default as to principal and interest. Lower-rated
securities generally provide greater income than higher-rated securities, but
are subject to greater market fluctuations and risks of loss of income and
principal than higher-rated securities. See "Common Investment Policies and
Techniques; Risk Factors -- Debt and Fixed Income Securities -- Lower-Rated
Securities" for more information concerning fixed income securities of below
investment grade quality.

         In selecting securities for the Portfolio, Western Asset may utilize
economic forecasting, interest rate anticipation, credit and call risk analysis,
and other security selection techniques. The proportion of assets committed to
investment in securities with particular characteristics (such as maturity, type
and coupon rate) will vary based on Western Asset's outlook for the U.S. and
foreign economies, the financial markets and other factors.

         The Portfolio may also invest in the following U.S. dollar-denominated
securities: mortgage- and other asset-backed securities; municipal obligations;
variable and floating rate debt securities; commercial paper and other
short-term investments; various corporate obligations (including preferred
stock, convertible securities, zero coupon securities and pay- in-kind
securities); common stocks and warrants; and certificates of deposit, fixed time
deposits and bankers' acceptances issued by domestic banks. The Portfolio may
also engage in repurchase agreements, reverse repurchase agreements and dollar
roll transactions. For more information, see "Common Investment Policies and
Techniques; Risk Factors" below.

         The Portfolio may invest up to 25% of its total assets in non-U.S.
dollar-denominated foreign securities. See "Common Investment Policies and
Techniques; Risk Factors -- Foreign Securities" for more information concerning
such investments.

                                      -24-



<PAGE>



         The Portfolio also may buy or sell interest rate futures contracts and
options on fixed income instruments and bond indices and options on interest
rate futures contracts to hedge against changes in the value of securities it
owns or anticipates purchasing or for non-hedging purposes. The Portfolio also
may purchase or sell securities on a forward commitment basis, engage in foreign
currency exchange transactions, lend its securities, and borrow money for
temporary or emergency purposes. See "Common Investment Policies and Techniques;
Risk Factors" below for more information about these practices.

                 WESTERN ASSET NON-U.S. FIXED INCOME PORTFOLIO

- --------------------------------------------------------------------------------
Adviser:     WAGM
- --------------------------------------------------------------------------------
Objective:   maximize total return, consistent with prudent investment
             management. "Total return" includes interest from underlying
             securities, capital gains and appreciation on the securities held
             in the Portfolio, and gains from the use of futures and options and
             from favorable changes in foreign currency exchange rates.
- --------------------------------------------------------------------------------

         Under normal market conditions, the Portfolio invests at least 75% of
its total assets in securities denominated in major foreign currencies and in
baskets of currencies (which may include U.S. and foreign currencies), such as
the European Currency Unit, or "ECU," or as other baskets of currencies may
further develop. WAGM anticipates that, under normal market conditions, all or
substantially all of the Portfolio's assets will be invested in securities of
foreign issuers. WAGM will manage the investments of the Portfolio across
different international bond markets so that, under normal market conditions,
the Portfolio's assets will be invested in securities of foreign issuers
representing at least three foreign countries. WAGM will select the Portfolio's
foreign country and currency composition based on its evaluation of relative
interest rates, inflation rates, exchange rates, monetary and fiscal policies,
trade and current account balances, and any other specific factors WAGM believes
relevant.

         In selecting securities for the Portfolio, WAGM may utilize economic
forecasting, interest rate anticipation, credit and call risk analysis, and
other security selection techniques. The proportion of assets committed to
investment in securities with particular characteristics (such as maturity, type
and coupon rate) will vary based on WAGM's outlook for the U.S. and foreign
economies, the financial markets and other factors.

         The Portfolio's foreign investments subject the Portfolio to greater
risks than those associated with domestic investments. See "Common Investment
Policies and Techniques; Risk Factors -- Foreign Securities" for more
information concerning these risks.

                                      -25-



<PAGE>



         Within the limits described above, the Portfolio may invest in a
variety of securities, including: U.S. dollar-denominated or foreign
currency-denominated obligations of foreign governments or their subdivisions,
agencies and instrumentalities, international agencies (such as the World Bank)
or supranational entities; foreign currency exchange-related securities,
including foreign currency warrants; obligations issued or guaranteed by the
U.S. Government, its agencies or instrumentalities; mortgage- and other
asset-backed securities; variable and floating rate debt securities; commercial
paper and other short-term investments; corporate obligations (including
preferred stock, convertible securities, zero coupon securities and pay-in-kind
securities); certificates of deposit, fixed time deposits and bankers'
acceptances; loan participations and assignments; indexed securities and
structured notes; and repurchase agreements collateralized by any security in
which it may invest. The Portfolio may also engage in reverse repurchase
agreements and dollar roll transactions and may borrow money for temporary or
emergency purposes. See "Common Investment Policies and Techniques; Risk
Factors" for more information.

         The Portfolio may invest up to 25% of its net assets in securities that
are rated at the time of purchase below investment grade or are of comparable
quality at the time of purchase as determined by WAGM. These securities are
commonly known as "junk bonds" or "high yield bonds." It is likely that a
substantial portion of these securities will be issued by issuers located in
emerging market countries. As a result, these securities are subject to special
risks. See "Common Investment Policies and Techniques; Risk Factors" below for
more information concerning lower-rated securities and securities issued by
issuers located in emerging market countries. In evaluating the credit risk of a
foreign debt security, the Portfolio may use ratings assigned by rating agencies
recognized in the primary market for those securities. In the event that the
rating of any security held by the Portfolio falls below its rating at the time
of purchase, the Portfolio will not be obligated to dispose of such security and
may continue to hold the security if, in the opinion of WAGM, such investment is
considered appropriate in the circumstances.

         The Portfolio also may buy or sell interest rate futures contracts and
options on fixed income instruments and bond indices and options on interest
rate futures contracts to hedge against changes in the value of securities it
owns or anticipates purchasing or for non-hedging purposes. The Portfolio may
buy or sell foreign currencies, foreign currency options, or foreign currency
futures contracts and related options, and may enter into foreign currency
forward contracts and other foreign currency exchange transactions for the
purpose of hedging against foreign exchange risk arising from the Portfolio's
investment or anticipated investment in securities denominated in foreign
currencies. The Portfolio also may engage in such transactions for purposes of
increasing exposure to a particular foreign currency or to shift exposure to
foreign currency fluctuations from one country to another. See "Common
Investment Policies and Techniques; Risk Factors" for more information about
these practices.

                                      -26-

         The Portfolio is "non-diversified" within the meaning of the Investment
Company Act. Accordingly, the Portfolio may invest a greater percentage of its
total assets in securities of any one issuer, or may invest in a smaller number
of different issuers, than it would if it were a "diversified" company under the
Investment Company Act. The Portfolio is therefore more susceptible to risks
associated with particular issuers and with the economic, political or
regulatory issues in a particular country or group of countries than would a
diversified portfolio.

         It is anticipated that from time to time over 25% of the Portfolio's
assets may be invested in securities of issuers located in a single country,
which is currently expected to be the case with respect to both Japanese and
German issuers. Such issuers may include the foreign governments of these
countries and their subdivisions, agencies, and instrumentalities, and also
non-governmental issuers. Whether the Portfolio will concentrate in foreign
governmental issuers or other issuers of these countries will depend on relative
market and economic circumstances from time to time. Among such circumstances
are the relative performance of these and other countries' fixed income markets,
expectations as to future relative performance of those markets, relative
foreign exchange rates, relative economic performance and expectations for these
and other foreign countries, and similar investment factors. The Portfolio will
concentrate in these countries or other countries when such circumstances
suggest the potential of a relatively higher return from such concentration. The
investment of a substantial amount of the Portfolio's assets in securities of
issuers from any such country raises special considerations for investors in
addition to the considerations generally applicable to foreign securities
described above.

         Japan currently has the second largest GNP in the world. While the
Japanese economy has grown substantially over the last three decades, with its
growth rate averaging over 5% in the 1970s and 1980s, the growth rate in Japan
has slowed substantially this decade. The economy is currently very weak and the
Bank of Japan continues to maintain a very loose monetary policy. The official
discount rate has been at .50 percent since September 1995.

         Germany currently has the third largest GNP in the world. It too has
grown substantially over the past few decades. The economy is now recovering
from a period of weak growth. The German Central Bank has reacted by raising
interest rates. This was also done to satisfy the requirement for rate
convergence in anticipation of the expected single currency in Europe. Inflation
remains at very moderate levels.

                WESTERN ASSET GLOBAL STRATEGIC INCOME PORTFOLIO

- --------------------------------------------------------------------------------
Advisers:         WAGM (Non-U.S. portion) and Western Asset (U.S. portion)
- --------------------------------------------------------------------------------
Objective:        income and capital appreciation
- --------------------------------------------------------------------------------

         The Portfolio seeks to achieve its investment objective by allocating
and reallocating its assets primarily among various types of U.S.
dollar-denominated and foreign currency denominated fixed income securities,
including mortgage-related and asset-backed securities; U.S. and foreign
investment-grade corporate securities; U.S. and foreign non-investment grade
corporate securities; sovereign debt obligations of developed nations; and debt
obligations of corporate and governmental issuers in developing countries, which
are sometimes referred to as emerging markets countries. Under normal market
conditions, the Portfolio will invest at least 80% of its total assets in
securities of issuers representing at least three countries, one of which may be
the U.S., and at least 65% of its total assets in income producing securities.

         WAGM will select the Portfolio's foreign country and currency
composition based on its evaluation of relative interest rates, inflation rates,
exchange rates, monetary and fiscal policies, trade and current account
balances, and any other specific factors WAGM believes relevant. In selecting
securities for the Portfolio, Western Asset and WAGM may utilize economic
forecasting, interest rate anticipation, credit and call risk analysis, and
other security selection techniques. The proportion of assets committed to
investment in securities with particular characteristics (such as maturity, type
and coupon rate) will vary based on WAGM's or Western Asset's outlook for the
U.S. and foreign economies, the financial markets and other factors.

         Mortgage-related securities in which the Portfolio may invest include
mortgage obligations collateralized by mortgage loans or mortgage pass-through
certificates. Asset- backed securities in which the Portfolio may invest include
obligations collateralized by credit card receivables, automotive loans and
leases as well as home equity loans.

         Investment-grade securities in which the Portfolio may invest include
bonds, debentures and notes of U.S. and foreign corporate issuers and warrants
on the same. At the time of purchase, these securities will be rated at least
investment grade by an NRSRO or, if not rated, will be deemed by Western Asset
or WAGM to be of comparable quality.

         The Portfolio may invest up to 100% of its assets in securities that
are rated at the time of purchase below investment grade or are of comparable
quality at the time of purchase as determined by WAGM or Western Asset. These
securities are commonly known as "junk bonds" or "high yield bonds." The
Portfolio may invest in securities that have an NRSRO's lowest rating, or in
non-rated securities deemed by WAGM or Western Asset to be of comparable
quality. Such ratings indicate that the obligations are highly speculative and
may

                                      -28-



<PAGE>



be in default or in danger of default as to principal and interest.
High-yielding corporate fixed income securities of foreign issuers in which the
Portfolio may invest will include securities of companies, wherever organized,
that have their principal business activities and interests outside the United
States. A substantial portion of these securities may be issued by issuers
located in emerging market countries. As a result, these securities are subject
to special risks. See "Common Investment Policies and Techniques; Risk Factors"
below for more information concerning lower-rated securities and securities
issued by issuers located in emerging market countries. In evaluating the credit
risk of a foreign debt security, the Portfolio may use ratings assigned by
rating agencies recognized in the primary market for those securities. In the
event that the rating of any security held by the Portfolio falls below its
rating at the time of purchase, the Portfolio will not be obligated to dispose
of such security and may continue to hold the security if, in the opinion of
WAGM or Western Asset, such investment is considered appropriate in the
circumstances.

         The Portfolio also may invest in securities issued by supranational
organizations, which are entities designated or supported by a government or
governmental entity to promote economic development, and include, among others,
the Asian Development Bank, the European Community, the European Investment
Bank, the Inter-American Development Bank, the International Monetary Fund, the
United Nations, the International Bank for Reconstruction and Development
("World Bank") and the European Bank for Reconstruction and Development. These
organizations have no taxing authority and are dependent upon their members for
payments of interest and principal. Moreover, the lending activities of such
supranational entities may be limited to a percentage of their total capital
(including "callable capital" contributed by members at an entity's call),
reserves and net income. Sovereign and supranational debt obligations in which
the Portfolio invests may have an NRSRO's lowest rating or in securities deemed
by WAGM to be of comparable quality.

         As noted above the Portfolio may also invest in debt obligations of
private and governmental issuers in countries with developing economies, which
are sometimes referred to as emerging market countries. These investments
include "Brady Bonds"; bonds issued as a result of a debt restructuring plan;
Eurobonds; domestic and international bonds issued under the laws of a
developing country; and emerging market loans. For more information concerning
the risks associated with investments in emerging markets, see "Common
Investment Policies and Techniques; Risk Factors -- Foreign Securities."

         The Portfolio's investments may be denominated in either U.S. dollars
or a variety of other currencies. The Portfolio's foreign investments subject
the Portfolio to greater risks than those associated with domestic investments.
See "Common Investment Policies and Techniques; Risk Factors -- Foreign
Securities" for more information concerning these risks.

         The Portfolio may invest in a variety of other securities, including:
foreign currency exchange-related securities, including foreign currency
warrants; shares of other investment companies; variable and floating rate debt
securities; commercial paper and other short-term

                                      -29-

investments; corporate obligations (including preferred stock, convertible
securities, zero coupon securities and pay-in-kind securities); municipal
obligations; certificates of deposit, fixed time deposits and bankers'
acceptances; loan participations and assignments; indexed securities and
structured notes; and repurchase agreements. The Portfolio may engage in reverse
repurchase agreements and dollar roll transactions, borrow money for temporary
or emergency purposes, loan its portfolio securities and purchase or sell
securities on a forward commitment basis. See "Common Investment Policies and
Techniques; Risk Factors" for more information.

         In addition, the Portfolio may buy or sell bond or interest rate
futures contracts and options on fixed income instruments and bond indices and
options on bond or interest rate futures contracts to hedge against changes in
the value of securities it owns or anticipates purchasing or for non-hedging
purposes. The Portfolio may buy or sell foreign currencies, foreign currency
options, or foreign currency futures contracts and related options, and may
enter into foreign currency forward contracts and other foreign currency
exchange transactions for the purpose of hedging against foreign exchange risk
arising from the Portfolio's investment or anticipated investment in securities
denominated in foreign currencies. The Portfolio also may engage in such
transactions for purposes of increasing exposure to a particular foreign
currency or to shift exposure to foreign currency fluctuations from one country
to another. See "Common Investment Policies and Techniques; Risk Factors" for
more information about these practices.

         The Portfolio is "non-diversified" within the meaning of the Investment
Company Act. Accordingly, the Portfolio may invest a greater percentage of its
total assets in securities of any one issuer, or may invest in a smaller number
of different issuers, than it would if it were a "diversified" company. The
Portfolio is therefore more susceptible to risks associated with particular

                    WESTERN ASSET ENHANCED EQUITY PORTFOLIO

- --------------------------------------------------------------------------------
Adviser:    Western Asset Management Company ("Western Asset")
- --------------------------------------------------------------------------------
Objective:  long term total return.  "Total return" includes all interest,
            dividends and other income, net of expenses, paid on the Portfolio's
            investments, as well as all realized and unrealized gains and
            losses.
- --------------------------------------------------------------------------------

          The Portfolio's assets will be comprised of two components: an equity
component and a fixed income component. As more fully described below, Western
Asset attempts to manage the equity component so that the Portfolio generally
maintains full exposure to the U.S. equity market as represented by the S&P 500
Index (the "Index"). Western Asset attempts to manage the Portfolio's fixed
income component in order to generate interest and

                                      -30-




<PAGE>



gains in excess of the Portfolio's expenses, including transaction costs related
to its investments. By investing in both components, the Portfolio expects that
its performance will approximate that of the Index, with the extent to which the
Portfolio outperforms or underperforms the Index depending largely on whether
the fixed income component has earned sufficient amounts to offset the
Portfolio's expenses.

         EQUITY COMPONENT. The Portfolio's equity component invests in common
stocks that are represented in the Index ("S&P stocks"), stock index futures,
options on stock indexes, options on stock index futures and other derivative
instruments that are based on the Index ("S&P derivatives"). The Portfolio may
invest in any combination of S&P stocks and S&P derivatives. Western Asset will
determine the appropriate mix of S&P stocks and S&P derivatives for the
Portfolio based on current market conditions and the expected costs and returns
of each, while seeking to control and limit overall risk. Based on current
market conditions, Western Asset currently expects that the Portfolio's equity
component will invest predominantly, and likely exclusively, in S&P derivatives.
To the extent S&P stocks are purchased by the Portfolio, the Portfolio will not
be limited to purchasing S&P stocks in the same proportion as such stocks are
weighted in the Index.

         The Index is composed of 500 selected common stocks, most of which are
listed on the New York Stock Exchange ("Exchange"). S&P chooses the stocks to be
included in the Index solely on a statistical basis. The weightings of stocks in
the Index are based on each stock's relative total market value, that is, its
market price per share times the number of shares outstanding. Stocks
represented currently in the Index represent approximately two-thirds of the
total market value of all U.S. publicly traded common stocks.

         Positions in S&P derivatives will be entered into only to the extent
they constitute permissible positions for the Portfolio according to applicable
rules of the Commodity Futures Trading Commission ("CFTC"). From time to time
Western Asset may be constrained in its ability to use S&P derivatives by, among
other things, CFTC rules or an unanticipated inability to close out positions
when it would be most advantageous to do so. For more information about S&P
derivatives, see "Common Investment Policies and Techniques; Risk Factors --
Options and Futures."

         The Portfolio is neither sponsored by nor affiliated with S&P. The
Portfolio will seek to remain invested in S&P stocks and S&P derivatives even
when the Index is declining.

         FIXED INCOME COMPONENT. The fixed income component will invest
primarily in the following types of securities: obligations issued or guaranteed
by the U.S. Government, its agencies or instrumentalities; fixed income
securities of non-governmental domestic or foreign issuers; municipal
securities; mortgage- and other asset-backed securities; preferred stocks; and
obligations of foreign governments or their subdivisions, agencies and
instrumentalities, international agencies or supranational entities. The fixed
income component may also invest in other securities or instruments, including
certificates of

                                      -31-




<PAGE>



deposit, time deposits and bankers' acceptances issued by domestic and foreign
banks and commercial paper and other short-term investments, and may engage in
repurchase agreements, reverse repurchase agreements and other borrowings and
purchase or sell futures contracts and options. Up to 10% of the Portfolio's net
assets may be invested in lower- rated securities (i.e., securities rated below
investment grade at the time of purchase or unrated securities of comparable
quality at the time of purchase) and up to 20% of its net assets may be invested
in foreign securities. The fixed income component may engage in foreign currency
exchange transactions in connection with its foreign investments. For more
information, see "Common Investment Policies and Techniques; Risk Factors."

COMMON INVESTMENT POLICIES AND TECHNIQUES;
RISK FACTORS
- --------------------------------------------------------------------------------

         Some or all of the Portfolios may engage in the following investment
practices and techniques to the extent described in this Prospectus. See the SAI
for a further description of the uses, risks and costs of these practices.

                               FOREIGN SECURITIES
- --------------------------------------------------------------------------------

         Investing in the securities of issuers in any foreign country, or in
securities denominated in a foreign currency, involves special risks and
considerations not typically associated with investing in U.S. issuers or U.S.
dollar-denominated securities. These include risks resulting from differences in
accounting, auditing and financial reporting standards; lower liquidity than
U.S. securities; the possibility of nationalization, expropriation or
confiscatory taxation; adverse changes in investment or exchange control
regulations (which may include suspension of the ability to transfer currency
out of a country); and political instability. In many cases, there is less
publicly available information concerning foreign issuers than is available
concerning U.S. issuers. Additionally, purchases and sales of foreign securities
and dividends and interest payable on those securities may be subject to foreign
taxes and tax withholding. Foreign securities generally exhibit greater price
volatility and a greater risk of illiquidity.

         To the extent a Portfolio purchases securities denominated in a foreign
currency, a change in the value of any such currency against the U.S. dollar
will result in a change in the U.S. dollar value of the Portfolio's assets and
the Portfolio's income available for distribution. In addition, a Portfolio is
required to compute and distribute its income in U.S. dollars. Therefore, if the
exchange rate for a foreign currency declines after a Portfolio's income has
been earned and translated into U.S. dollars (but before payment), the Portfolio
could be required to liquidate portfolio securities to make such distributions.
Similarly, if an

                                      -32-




<PAGE>



exchange rate declines between the time a Portfolio incurs expenses in U.S.
dollars and the time such expenses are paid, the amount of such currency
required to be converted into U.S. dollars in order to pay such expenses in U.S.
dollars will be greater than the equivalent amount in any such currency of such
expenses at the time they were incurred.

         The relative performance of various countries' securities markets
historically has reflected wide variations relating to the unique
characteristics of each country's economy. Individual foreign economies may
differ favorably or unfavorably from the U.S. economy in such respects as growth
of gross domestic product, rate of inflation, capital reinvestment, resource
self-sufficiency and balance of payments position. Bank deposit insurance, if
any, may be subject to widely varying regulations and limits in foreign
countries.

         Foreign securities purchased by a Portfolio may be listed on foreign
exchanges, traded over-the-counter or purchased in private transactions.
Transactions on foreign exchanges are usually subject to mark-ups or commissions
higher than negotiated commissions on U.S. transactions. There is less
government supervision and regulation of exchanges and brokers in many foreign
countries than in the United States. Additional costs associated with an
investment in foreign securities may include higher custodial fees than apply to
domestic custodial arrangements and transaction costs of foreign currency
conversions.

         Certain of the foregoing risks may also apply to some extent to
securities of U.S. issuers that are denominated in foreign currencies or that
are traded in foreign markets, or to securities of U.S. issuers having
significant foreign operations.

         EMERGING MARKET ISSUERS. The risks of foreign investment, described
above, are greater for investments in emerging market issuers, and such
investments should therefore be considered speculative. Debt securities of
governmental and other issuers in emerging market countries will typically be
rated below investment grade or be of comparable quality. For more information
about lower-rated securities, see "Debt and Fixed Income Securities --
Lower-Rated Securities" below.

         Investors are strongly advised to consider carefully the special risks
involved in emerging markets, which are in addition to the usual risks of
investing in developed markets around the world. Emerging market countries may
experience substantial rates of inflation or deflation. Inflation, deflation and
rapid fluctuations in such rates have had, and may continue to have, very
negative effects on the economies and securities markets of certain emerging
market countries. While some emerging market countries have sought to develop a
number of corrective mechanisms to reduce inflation or deflation or mitigate
their effects, inflation and deflation may continue to have significant effects
both on emerging market countries and their securities markets. In addition,
many of the currencies of emerging market countries have experienced steady
devaluations relative to the U.S. dollar, and major devaluations have occurred
in certain countries.

                                      -33-




<PAGE>



         Economies in emerging market countries generally are dependent heavily
upon international trade and, accordingly, have been and may continue to be
affected adversely by economic conditions, trade barriers, exchange controls,
managed adjustments in relative currency values and other protectionist measures
imposed or negotiated by the countries with which they trade.

         Because of the high levels of foreign-denominated debt owed by many
emerging market countries, fluctuating exchange rates can significantly affect
the debt service obligations of those countries. This could, in turn, affect
local interest rates, profit margins and exports, which are a major source of
foreign exchange earnings. Hedging instruments are not typically available with
respect to investments in emerging market countries and, to the extent they are
available, the ongoing and indeterminate nature of the foregoing risks (and the
costs associated with hedging transactions) would make it virtually impossible
to hedge effectively against such risks.

         To the extent an emerging market country faces a liquidity crisis with
respect to its foreign exchange reserves, it may increase restrictions on the
outflow of any foreign exchange. Repatriation is ultimately dependent on the
ability of a Portfolio to liquidate its investments and convert the local
currency proceeds obtained from such liquidation into U.S. dollars. Where this
conversion must be done through official channels (usually the central bank or
certain authorized commercial banks), the ability to obtain U.S. dollars is
dependent on the supply of such U.S. dollars through those channels and, if
available, upon the willingness of those channels to allocate those U.S. dollars
to the Portfolio. In such a case, a Portfolio's ability to obtain U.S. dollars
may be adversely affected by any increased restrictions imposed on the outflow
of foreign exchange. If the Portfolio is unable to repatriate any amounts due to
exchange controls, it may be required to accept an obligation payable at some
future date by the central bank or other governmental entity of the jurisdiction
involved. If such conversion can legally be done outside official channels,
either directly or indirectly, a Portfolio's ability to obtain U.S. dollars may
not be affected as much by any increased restrictions except to the extent of
the price which may be required to be paid for the U.S. dollars.

         Many emerging market countries have little experience with the
corporate form of business organization, and may not have well developed
corporation and business laws or concepts of fiduciary duty in the business
context. The securities markets of emerging market countries are substantially
smaller, less developed, less liquid and more volatile than the securities
markets of the U.S. and other more developed countries. Disclosure and
regulatory standards in many respects are less stringent than in the U.S. and
other major markets. There also may be a lower level of monitoring and
regulation of an emerging market country's securities markets and the activities
of investors in such markets; enforcement of existing regulations has been
extremely limited.

                                      -34-




<PAGE>



         Some emerging markets have different settlement and clearance
procedures, which, for example, may not call for delivery of a security to a
Portfolio until well after the Portfolio has paid for such security. In certain
markets there have been times when settlements have been unable to keep pace
with the volume of securities transactions, making it difficult to conduct such
transactions. The inability of a Portfolio to make intended securities purchases
due to settlement problems could cause that Portfolio to miss attractive
investment opportunities. Inability to dispose of a portfolio security caused by
settlement problems could result either in losses to the Portfolio due to
subsequent declines in value of the portfolio security or, if the Portfolio has
entered into a contract to sell the security, in possible liability to the
purchaser.

         The risk also exists that an emergency situation may arise in one or
more emerging market countries as a result of which trading of securities may
cease or may be substantially curtailed and prices for a Portfolio's portfolio
securities in such markets may not be readily available.

         SOVEREIGN DEBT SECURITIES. Sovereign debt is subject to risks in
addition to those relating to foreign investments generally. As a sovereign
entity, the issuing government may be immune from lawsuits in the event of its
failure or refusal to pay the obligations when due. The debtor's willingness or
ability to repay in a timely manner may be affected by, among other factors, its
cash flow situation, the extent of its foreign reserves, the availability of
sufficient foreign exchange on the date a payment is due, the relative size of
the debt service burden to the economy as a whole, the sovereign debtor's policy
toward principal international lenders and the political constraints to which
the sovereign debtor may be subject. Sovereign debtors also may be dependent on
expected disbursements from foreign governments or multinational agencies, the
country's access to trade and other international credits, and the country's
balance of trade. Some emerging market sovereign debtors have in the past
rescheduled their debt payments or declared moratoria on payments, and similar
occurrences may happen in the future.

         DEPOSITARY RECEIPTS. American Depositary Receipts, or "ADRs," are
securities issued by a U.S. depositary (usually a bank) and represent a
specified quantity of underlying non-U.S. securities on deposit with a custodian
bank as collateral. A foreign issuer of the security underlying an ADR is
generally not subject to the same reporting requirements in the United States as
a domestic issuer. Accordingly, the information available to a U.S. investor
will be limited to the information the foreign issuer is required to disclose in
its own country and the market value of an ADR may not reflect undisclosed
material information concerning the issuer or the underlying security. ADRs may
also be subject to exchange rate risks if the underlying securities are
denominated in foreign currency. The Portfolios may also invest in similar
non-U.S. instruments issued by foreign banks or trust companies such as "GDRs"
and "EDRs." For purposes of its investment policies, each Portfolio will treat
ADRs and similar instruments as equivalent to investment in the underlying
securities.

<PAGE>




                              OPTIONS AND FUTURES
- --------------------------------------------------------------------------------

         A futures contract is an agreement between the parties to buy or sell a
specified amount of one or more securities, units of an index or currencies at a
specified price and date; futures contracts are generally closed out by the
parties in advance of that date for a cash settlement. Under an option contract,
one party generally has the right to require the other to buy or sell a
specified amount of securities, units of an index, currencies or futures
contracts, and may exercise that right if the market price of the underlying
instrument moves in a direction advantageous to the holder of the option.
Options with respect to securities indices typically call for cash settlement
instead of delivery of the securities that comprise the index. Options and
futures are generally considered to be "derivatives."

         The Portfolios may buy, sell and write options and futures for hedging
purposes and, to the extent permitted by applicable law, for non-hedging
purposes, such as to earn additional income. Futures contracts and options may
also be used for other non-hedging purposes, such as to simulate full investment
in underlying securities while retaining a cash balance for Portfolio management
purposes, as a substitute for direct investment in a security, to facilitate
trading, to reduce transaction costs, or to seek higher investment returns when
a futures contract or option is priced more attractively than the underlying
security or index.

         The use of options and futures involves certain investment risks and
transaction costs. These risks include (1) difficulty in predicting movements in
the prices of individual securities or an index, fluctuations in the general
securities markets or in market sectors and movements in interest rates and
currency markets; (2) imperfect correlation, or no correlation at all, between
movements in the price of options and futures contracts, movements in the price
of the underlying instruments, index or currencies and movements in the
securities or currencies that are the subject of a hedge; (3) the fact that
skills needed to use these instruments are different from those needed to select
a Portfolio's other investments; (4) the possible lack of a liquid secondary
market for any particular instrument at any particular time; (5) the possibility
that the use of cover or segregation involving a large percentage of a
Portfolio's assets could impede portfolio management or the Portfolio's ability
to meet redemption requests or other short-term obligations; and (6) the fact
that, although use of these instruments for hedging purposes can reduce the risk
of loss, they can also reduce the opportunity for gain, or even result in
losses, by offsetting favorable price movements in hedged investments. There can
be no assurance that a Portfolio's use of futures contracts or options will be
successful. Moreover, in the event that an anticipated change in the price of
the instruments, index or currencies that are the subject of the strategy does
not occur, the Portfolio might have been in a better position had it not used
that strategy at all. Options and futures traded on U.S. or other exchanges may
be subject to position and daily fluctuation limits, which may limit the ability
of a Portfolio to reduce risk using such options and futures and may limit their
liquidity.

                                      -36-




<PAGE>



         The use of options and futures contracts for speculative purposes,
e.g., to enhance income or to increase a Portfolio's exposure to a particular
security or type of security or a particular foreign currency, subjects the
Portfolio to additional risk. The use of options and futures to hedge an
anticipated purchase also subjects a Portfolio to additional risk until the
purchase is completed or the position is closed out.

         Many options on securities are traded primarily on the over-the-counter
("OTC") market. OTC options are two-party contracts with price and other terms
negotiated between buyer and seller and generally do not have much, if any,
liquidity. Thus, when a Portfolio purchases an OTC option, it relies on the
dealer from which it has purchased the option to make or take delivery of the
instruments underlying the option or otherwise fulfill its obligations under the
contract. Failure by the dealer to do so would result in the loss of the premium
paid by that Portfolio as well as the loss of the expected benefit of the
transaction. OTC options may be considered "illiquid securities" for purposes of
each Portfolio's investment limitations.

                     FOREIGN CURRENCY EXCHANGE TRANSACTIONS
- --------------------------------------------------------------------------------

         Each Portfolio that may invest in securities that are denominated in
foreign currencies may engage in a variety of foreign currency exchange
transactions to protect against uncertainty in the level of future exchange
rates. These transactions may be engaged in connection with the purchase and
sale of portfolio securities ("transaction hedging") and to protect the value of
specific portfolio positions ("position hedging").

         A Portfolio may engage in transaction hedging to protect against a
change in the foreign currency exchange rates between the date on which the
Portfolio contracts to purchase or sell the security and the settlement date, or
to "lock in" the U.S. dollar equivalent of a dividend or interest payment in a
foreign currency. A Portfolio may purchase or sell a foreign currency on a spot
(or cash) basis at the prevailing spot rate. If conditions warrant, for
transaction hedging purposes, a Portfolio may also enter into contracts to
purchase or sell foreign currencies at a future date ("forward contracts") and
may purchase and sell foreign currency futures contracts. A foreign currency
forward contract is a negotiated agreement to exchange currency at a future time
at a rate or rates that may be higher or lower than the spot rate. Foreign
currency futures contracts are standardized exchange-traded contracts and have
margin requirements. Each Portfolio may also purchase, sell and write
exchange-listed and over-the-counter call and put options on foreign currency
futures contracts and on foreign currencies.

         A Portfolio may engage in "position hedging" to protect against a
decline in the value relative to the U.S. dollar of the currencies in which its
portfolio securities are denominated or quoted (or an increase in the value of
the currency in which securities the Portfolio intends to buy are denominated,
when the Portfolio holds cash reserves or short-term investments).

                                      -37-




<PAGE>



For position hedging purposes, each Portfolio may purchase, sell or write
foreign currency futures contracts, foreign currency forward contracts, and
options on exchanges or over-the-counter markets. In connection with position
hedging, a Portfolio may also purchase or sell foreign currency on a spot basis.

         A Portfolio's currency hedging transactions may call for the delivery
of one foreign currency in exchange for another foreign currency and may at
times involve currencies other than those in which its portfolio securities are
then denominated. "Cross hedging" activities will be used when a Portfolio's
Adviser believes that such transactions provide significant hedging
opportunities for the Portfolio. Cross hedging transactions by a Portfolio
involve the further risk of imperfect correlation between changes in the values
of the currencies to which such transactions relate and changes in the values of
such currencies and of the currency or other asset or liability which is the
subject of the hedge.

         The decision as to whether and to what extent a Portfolio will engage
in foreign currency exchange transactions will depend on a number of factors,
including prevailing market conditions, the composition of a Portfolio's
investments and the availability of suitable transactions. Accordingly, there
can be no assurance that a Portfolio will engage in foreign currency exchange
transactions at any given time or from time to time.

         For a further discussion of the risks associated with purchasing and
selling futures contracts and options, see "Options and Futures" above. A
Portfolio may also use other foreign currency exchange instruments and
techniques when available and deemed appropriate by its Adviser.

                  PREFERRED STOCKS AND CONVERTIBLE SECURITIES
- --------------------------------------------------------------------------------

         A preferred stock pays dividends at a specified rate and has preference
over common stock in the payment of dividends and the liquidation of an issuer's
assets but is junior to the debt securities of the issuer in those same
respects. The market prices of preferred stocks are subject to changes in
interest rates and are more sensitive to changes in an issuer's creditworthiness
than are the prices of debt securities. Shareholders of preferred stock may
suffer a loss of value if dividends are not paid. Under ordinary circumstances,
preferred stock does not carry voting rights.

         A convertible security is a bond, debenture, note, preferred stock or
other security that may be converted into or exchanged for a prescribed amount
of common stock (or another equity security) of the same or a different issuer
within a particular period of time at a specified price or formula. A
convertible security entitles the holder to receive interest paid or accrued on
debt or the dividend paid on preferred stock until the convertible security
matures or is redeemed, converted or exchanged. Before conversion, convertible
securities have characteristics similar to nonconvertible debt securities in
that they ordinarily provide a

                                      -38-




<PAGE>



stream of income with generally higher yields than those of common stocks of the
same or similar issuers. Convertible securities are usually subordinated to
comparable-tier nonconvertible securities but rank senior to common stock in a
corporation's capital structure.

         The value of a convertible security is a function of (1) its yield in
comparison with the yields of other securities of comparable maturity and
quality that do not have a conversion privilege and (2) its worth, at market
value, if converted into the underlying common stock. A convertible security may
be subject to redemption at the option of the issuer at a price established in
the convertible security's governing instrument. If a convertible security held
by a Portfolio is called for redemption, the Portfolio will be required to (1)
permit the issuer to redeem the security, (2) convert it into the underlying
common stock or (3) sell it to a third party. Any of these actions could have an
adverse effect on a Portfolio's ability to achieve its investment objective.

                        DEBT AND FIXED INCOME SECURITIES
- --------------------------------------------------------------------------------

         The Portfolios may invest in a variety of debt and fixed income
securities. These securities share one principal risk: their values fluctuate
with changes in interest rates. Thus, a decrease in interest rates will
generally result in an increase in the value of a Portfolio's fixed income
investments. Conversely, during periods of rising interest rates, the value of a
Portfolio's fixed income investments will generally decline. The magnitude of
these fluctuations will generally be greater when a Portfolio's duration or
average maturity is longer. Changes in the value of portfolio securities will
not affect interest income from those securities, but will be reflected in a
Portfolio's net asset value. The most common types of these instruments, and the
associated risks, are described below. Subject to its investment policies and
applicable law, each of the Portfolios may invest in these instruments.

         U.S. GOVERNMENT OBLIGATIONS. U.S. Government securities include (1)
U.S. Treasury bills (maturity of one year or less), U.S. Treasury notes
(maturity of one to ten years) and U.S. Treasury bonds (maturities generally
greater than ten years) and (2) obligations issued or guaranteed by U.S.
Government agencies or instrumentalities which are supported by any of the
following: (a) the full faith and credit of the U.S. Government (such as GNMA
certificates); (b) the right of the issuer to borrow an amount limited to a
specific line of credit from the U.S. Government (such as obligations of the
Federal Home Loan Banks); (c) the discretionary authority of the U.S. Government
to purchase certain obligations of agencies or instrumentalities (such as
securities issued by FNMA); or (d) only the credit of the instrumentality (such
as securities issued by Freddie Mac). In the case of obligations not backed by
the full faith and credit of the United States, a Portfolio must look
principally to the agency or instrumentality issuing or guaranteeing the
obligation for ultimate repayment and may not be able to assert a claim against
the United States itself in the event the agency or instrumentality does not
meet its commitments. Neither the U.S.

                                      -39-




<PAGE>



Government nor any of its agencies or instrumentalities guarantees the market
value of the securities they issue. Therefore, the market value of such
securities will fluctuate in response to changes in interest rates.

         INFLATION-INDEXED SECURITIES. The Portfolios may also invest in
inflation-indexed U.S. Treasury securities (also known as "Treasury
Inflation-Protection Securities"). The principal value of Treasury
Inflation-Protection Securities is adjusted daily in accordance with changes in
the Consumer Price Index, while interest is calculated on the basis of the
adjusted principal value on the payment date. The principal value of these
securities declines in periods of deflation, but holders at maturity receive no
less than par. If inflation is lower than expected during the period a Portfolio
holds the security, the Portfolio may earn less on the security than on a
conventional bond. Any increase in principal value is taxable in the year the
increase occurs, even though holders do not receive cash representing the
increase at that time. Changes in market interest rates from causes other than
inflation will likely affect the price of these securities in the same manner as
more traditional obligations.

         MORTGAGE-RELATED SECURITIES. Mortgage-related securities represent an
interest in a pool of mortgages made by lenders such as commercial banks,
savings and loan institutions, mortgage bankers and others. Mortgage-related
securities may be issued by governmental, government-related or non-governmental
entities, and provide regular payments which consist of interest and, in most
cases, principal. In contrast, other forms of debt securities normally provide
for periodic payment of interest in fixed amounts with principal payments at
maturity or specified call dates. In effect, payments on mortgage-related
securities are a "pass-through" of the payments made by the individual borrowers
on their mortgage loans, net of any fees paid to the issuer or guarantor of such
securities. Additional payments to holders of mortgage-related securities are
caused by repayments resulting from the sale of the underlying property,
refinancing or foreclosure, net of fees or costs which may be incurred.

         As prepayment rates of individual pools of mortgage loans vary widely,
it is not possible to predict accurately the average life of a particular
security. Although mortgage-related securities are issued with stated maturities
of up to forty years, unscheduled or early payments of principal and interest on
the underlying mortgages may shorten considerably the securities' effective
maturities. The volume of prepayments of principal on a pool of mortgages
underlying a particular mortgage-related security will influence the yield of
that security, and the principal returned to a Portfolio may be reinvested in
instruments whose yield may be higher or lower than that which might have been
obtained had such prepayments not occurred. When interest rates are declining,
such prepayments usually increase, and reinvestments of such principal
prepayments will be at a lower rate than that on the original mortgage-related
security. An increase in mortgage prepayments could cause the Portfolio to incur
a loss on a mortgage-related security that was purchased at a premium. On the
other hand, a decrease in the rate of prepayments, resulting from an increase in
market interest rates or other causes, may extend the effective maturities of
mortgage-related securities, increasing their sensitivity to changes in market
interest rates and potentially

                                      -40-




<PAGE>



increasing the volatility of a Portfolio's shares. The rate of prepayment may
also be affected by general economic conditions, the location and age of the
mortgages, and other social and demographic conditions. In determining the
average maturity or duration of a mortgage-related security, a Portfolio's
Adviser must apply certain assumptions and projections about the maturity and
prepayment of such security; actual prepayment rates may differ. Because of
prepayments, mortgage-related securities may have less potential for capital
appreciation during periods of declining interest rates than other securities of
comparable maturities, although they may have a similar risk of decline in
market value during periods of rising interest rates.

         GOVERNMENT MORTGAGE-RELATED SECURITIES. GNMA is the principal federal
government guarantor of mortgage-related securities. GNMA is a wholly owned U.S.
Government corporation within the Department of Housing and Urban Development.
GNMA pass-through securities are considered to have a relatively low risk of
default in that (1) the underlying mortgage loan portfolio is comprised entirely
of government-backed loans and (2) the timely payment of both principal and
interest on the securities is guaranteed by the full faith and credit of the
U.S. Government, regardless of whether they have been collected. GNMA
pass-through securities are, however, subject to the same market risk as
comparable debt securities. Therefore, the effective maturity and market value
of a Portfolio's GNMA securities can be expected to fluctuate in response to
changes in interest rate levels.

         Residential mortgage loans are also pooled by Freddie Mac, a corporate
instrumentality of the U.S. Government. The mortgage loans in Freddie Mac's
portfolio are not government backed; Freddie Mac, not the U.S. Government,
guarantees the timely payment of interest and ultimate collection of principal
on Freddie Mac securities. Freddie Mac also issues guaranteed mortgage
certificates, on which it guarantees semiannual interest payments and a
specified minimum annual payment of principal.

         FNMA is a government-sponsored corporation owned entirely by private
stockholders. It is subject to general regulation by the Secretary of Housing
and Urban Development. FNMA purchases residential mortgages from a list of
approved seller/servicers, which include savings and loan associations, savings
banks, commercial banks, credit unions and mortgage bankers. Pass-through
securities issued by FNMA are guaranteed as to timely payment of principal and
interest only by FNMA, not the U.S. Government.

         PRIVATELY ISSUED MORTGAGE-RELATED SECURITIES. Mortgage-related
securities offered by private issuers include pass-through securities comprised
of pools of residential mortgage loans; mortgage-backed bonds which are
considered to be debt obligations of the institution issuing the bonds and are
collateralized by mortgage loans; and bonds and collateralized mortgage
obligations ("CMOs") which are collateralized by mortgage-related securities
issued by Freddie Mac, FNMA or GNMA or by pools of mortgages.

                                      -41-

         CMOs are typically structured with classes or series which have
different maturities and are generally retired in sequence. Each class of
obligations receives periodic interest payments according to the coupon rate on
the obligations. However, all monthly principal payments and any prepayments
from the collateral pool are generally paid first to the "Class 1" holders.
Thereafter, all payments of principal are generally allocated to the next most
senior class of obligations until that class of obligations has been fully
repaid. Although full payoff of each class of obligations is contractually
required by a certain date, any or all classes of obligations may be paid off
sooner than expected because of an increase in the payoff speed of the pool.
Other allocation methods may be used. Payment of interest or principal on some
classes or series of a CMO may be subject to contingencies or some classes or
series may bear some or all of the risk of default on the underlying mortgages.

         Mortgage-related securities created by non-governmental issuers
generally offer a higher rate of interest than government and government-related
securities because there are no direct or indirect government guarantees of
payment in the former securities, resulting in higher risks. Where privately
issued securities are collateralized by securities issued by Freddie Mac, FNMA
or GNMA, the timely payment of interest and principal is supported by the
government-related securities collateralizing such obligations. The market for
conventional pools is smaller and less liquid than the market for the government
and government-related mortgage pools.

         ASSET-BACKED SECURITIES. Asset-backed securities refer to securities
that directly or indirectly represent a participation in, or are secured by and
payable from, assets such as motor vehicle installment sales, installment loan
contracts, leases of various types of real and personal property and receivables
from revolving credit (credit card) agreements. Such assets are securitized
through the use of trusts or special purpose corporations. Asset-backed
securities are backed by a pool of assets representing the obligations often of
a number of different parties. Certain of such securities may be illiquid.

         The principal on asset-backed securities, like that on mortgage-backed
securities, may be prepaid at any time. As a result, if such securities are
purchased at a premium, a prepayment rate that is faster than expected will
reduce yield to maturity, while a prepayment rate that is slower than expected
will have the opposite effect. Conversely, if the securities are purchased at a
discount, prepayments faster than expected will increase yield to maturity and
prepayments slower than expected will decrease it. Accelerated prepayments also
reduce the certainty of the yield because the Portfolio must reinvest the assets
at the then-current rates. Accelerated prepayments on securities purchased at a
premium also impose a risk of loss of principal.

         Each type of asset-backed security also entails unique risks depending
on the type of assets involved and the legal structure used. For example, credit
card receivables are generally unsecured obligations of the credit card holder
and the debtors are entitled to the protection of a number of state and federal
consumer credit laws, many of which give such

                                      -42-




<PAGE>



debtors the right to set off certain amounts owed on the credit cards, thereby
reducing the balance due. There have also been proposals to cap the interest
rate that a credit card issuer may charge. In some transactions, the value of
the asset-backed security is dependent on the performance of a third party
acting as credit enhancer or servicer. Furthermore, in some transactions (such
as those involving the securitization of vehicle loans or leases) it may be
administratively burdensome to perfect the interest in the underlying
collateral, and the underlying collateral may become damaged or stolen.

         MUNICIPAL OBLIGATIONS. Municipal obligations include obligations issued
to obtain funds for various public purposes, including constructing a wide range
of public facilities, such as bridges, highways, housing, hospitals, mass
transportation, schools and streets. Other public purposes for which municipal
obligations may be issued include the refunding of outstanding obligations, the
obtaining of funds for general operating expenses and the making of loans to
other public institutions and facilities. In addition, certain types of
industrial development bonds ("IDBs") and private activity bonds ("PABs") are
issued by or on behalf of public authorities to finance various privately
operated facilities, including certain pollution control facilities, convention
or trade show facilities, and airport, mass transit, port or parking facilities.

         Municipal obligations also include short-term tax anticipation notes,
bond anticipation notes, revenue anticipation notes and other forms of
short-term debt obligations. Such notes may be issued with a short-term maturity
in anticipation of the receipt of tax payments, the proceeds of bond placements
or other revenues. Municipal obligations also include municipal lease
obligations and certificates of participation. Municipal lease obligations,
which are issued by state and local governments to acquire land, equipment and
facilities, typically are not fully backed by the municipality's credit, and, if
funds are not appropriated for the following year's lease payments, a lease may
terminate, with the possibility of default on the lease obligation and
significant loss to the Portfolio. Certificates of participation are
participations in municipal lease obligations or installment sales contracts.
Each certificate represents a proportionate interest in or right to the payments
made.

         The two principal classifications of municipal obligations are "general
obligation" and "revenue" bonds. "General obligation" bonds are secured by the
issuer's pledge of its faith, credit and taxing power. "Revenue" bonds are
payable only from the revenues derived from a particular facility or class of
facilities or from the proceeds of a special excise tax or other specific
revenue source such as the corporate user of the facility being financed. IDBs
and PABs are usually revenue bonds and are not payable from the unrestricted
revenues of the issuer. The credit quality of IDBs and PABs is usually directly
related to the credit standing of the corporate user of the facilities.

         The ability of state, county or local governments to meet their
obligations will depend primarily on the availability of tax and other revenues
to those governments and on their fiscal conditions generally. The amounts of
tax and other revenues available to governmental

                                      -43-




<PAGE>



issuers may be affected from time to time by economic, political and demographic
conditions within or outside of the particular state. In addition,
constitutional or statutory restrictions may limit a government's power to raise
revenues or increase taxes. The availability of federal, state and local aid to
issuers of municipal securities may also affect their ability to meet their
obligations. Payments of principal and interest on revenue bonds will depend on
the economic condition of the facility or specific revenue source from whose
revenues the payments will be made. The facility's economic status, in turn,
could be affected by economic, political and demographic conditions affecting
the particular state.

         CORPORATE DEBT SECURITIES. A Portfolio may invest in debt securities
(i.e., bonds, debentures, notes and other similar debt instruments) of domestic
or foreign non-governmental issuers which meet the minimum credit quality
criteria, if any, set forth for the Portfolio. Corporate debt securities may pay
fixed or variable rates of interest, or interest at a rate contingent upon some
other factor, such as the price of some commodity. These securities may include
warrants, may be convertible into preferred or common equity, or may be bought
as part of a unit containing common stock.

         LOWER-RATED SECURITIES. Non-investment grade securities, i.e.,
securities rated below Baa by Moody's or BBB by S&P or comparable ratings of
other NRSROs or unrated securities of comparable quality, are described as
"speculative" by Moody's and S&P and may be subject to greater market
fluctuations 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. Such securities are commonly
referred to as "junk bonds." A Portfolio's Adviser seeks to minimize the risks
of investing in all securities through diversification, in-depth credit analysis
and attention to current developments in interest rates and market conditions
and will monitor the ratings of securities held by the Portfolios and the
creditworthiness of their issuers. If the rating of a security in which a
Portfolio has invested falls below the minimum rating in which the Portfolio is
permitted to invest, the Portfolio will either dispose of that security within a
reasonable time or hold the security for so long as the Portfolio's Adviser
determines appropriate for that Portfolio, having due regard for market
conditions, tax implications and other applicable factors. See the Appendix to
this Prospectus for a description of the ratings assigned to fixed income
securities by the rating agencies.

         A debt security may be callable, i.e., subject to redemption at the
option of the issuer at a price established in the security's governing
instrument. If a debt security held by a Portfolio is called for redemption, the
Portfolio will be required to permit the issuer to redeem the security or sell
it to a third party. Either of these actions could have an adverse effect on a
Portfolio's ability to achieve its investment objective because, for example,
the Portfolio may be able to reinvest the proceeds only in securities with lower
yields or may receive a price upon sale that is lower than it would have
received in the absence of the redemption.

                                      -44-




<PAGE>



         The prices of debt securities fluctuate in response to perceptions of
the issuer's creditworthiness. Generally, lower-rated securities offer a higher
current yield than that provided by higher grade issues, but also involve higher
risks. Debt securities rated C by an NRSRO are bonds on which no interest is
being paid and which can be regarded as having extremely poor prospects of ever
attaining any real investment standing. Debt securities rated D by an NRSRO are
bonds that are in default or arrears and have questionable value. Lower-rated
securities are especially affected by adverse changes in the industries in which
the issuers are engaged and by changes in the financial condition of the
issuers. Highly leveraged issuers may also experience financial stress during
periods of rising interest rates.

         The market for lower-rated securities has expanded rapidly in recent
years. This growth has paralleled a long economic expansion. At certain times in
the past, the prices of many lower-rated securities declined, indicating
concerns that issuers of such securities might experience financial
difficulties. At those times, the yields on lower-rated securities rose
dramatically, reflecting the risk that holders of such securities could lose a
substantial portion of their value as a result of the issuers' financial
restructuring or default. There can be no assurance that such declines will not
recur.

         The market for lower-rated securities is generally thinner and less
active than that for higher quality debt securities, which may make it difficult
for a Portfolio to value its securities or may limit a Portfolio's ability to
sell such securities at fair value. As a result, judgment plays a greater role
in pricing such securities than is the case for securities having more active
markets. Adverse publicity and investor perceptions, whether or not based on
fundamental analysis, may also decrease the values and liquidity of lower-rated
securities, especially in a thinly traded market.

         The ratings of Moody's and S&P represent the opinions of those agencies
as to the quality of the debt securities which they rate. Such ratings are
relative and subjective, and are not absolute standards of quality. Unrated debt
securities are not necessarily of lower quality than rated securities, but they
may not be attractive to as many buyers. If securities are rated investment
grade by one rating organization and below investment grade by the other, a
Portfolio's investment adviser may rely on the rating that it believes is more
accurate. Each Portfolio's Adviser will consider a security's quality and credit
rating when determining whether such security is an appropriate investment.
Subject to its investment objective, policies and applicable law, a Portfolio
may purchase a security with the lowest rating.

         STRIPPED SECURITIES. Stripped securities are created by separating
bonds into their principal and interest components and selling each piece
separately (commonly referred to as IOs and POs). The yield to maturity on an IO
or PO class of stripped mortgage-backed securities is extremely sensitive not
only to changes in prevailing interest rates but also to the rate of principal
payments (including prepayments) on the underlying assets. A rapid rate of
principal prepayments may have a measurably adverse effect on a Portfolio's
yield to

                                      -45-




<PAGE>



maturity to the extent it invests in IOs. If the assets underlying the IOs
experience greater than anticipated prepayments of principal, the fund may fail
to recoup fully its initial investment in these securities. Conversely, POs tend
to increase in value if prepayments are greater than anticipated and decline if
prepayments are slower than anticipated. The secondary market for stripped
mortgage-backed securities may be more volatile and less liquid than that for
other mortgage-backed securities, potentially limiting a Portfolio's ability to
buy or sell those securities at any particular time.

         ZERO COUPON AND PAY-IN-KIND SECURITIES. A zero coupon bond is a
security that makes no fixed interest payments but instead is sold at a discount
from its face value. The bond is redeemed at its face value on the specified
maturity date. Zero coupon bonds may be issued as such, or they may be created
by a broker who strips the coupons from a bond and separately sells the rights
to receive principal and interest. The prices of zero coupon bonds tend to
fluctuate more in response to changes in market interest rates than do the
prices of interest-paying debt securities with similar maturities. A Portfolio
investing in zero coupon bonds generally accrues income on such securities prior
to the receipt of cash payments. Since each Portfolio must distribute
substantially all of its income to shareholders to qualify as a regulated
investment company under federal income tax law, a Portfolio investing in zero
coupon bonds may have to dispose of other securities to generate the cash
necessary for the distribution of income attributable to its zero coupon bonds.
Pay-in-kind securities have characteristics similar to those of zero coupon
securities, but interest on such securities may be paid in the form of
obligations of the same type rather than cash.

               COMMERCIAL PAPER AND OTHER SHORT-TERM INVESTMENTS
- --------------------------------------------------------------------------------

         Each of the Portfolios may invest or hold cash or other short-term
investments, including commercial paper. Commercial paper represents short-term
unsecured promissory notes issued in bearer form by banks or bank holding
companies, corporations and finance companies. The Portfolios may purchase
commercial paper issued pursuant to the private placement exemption in Section
4(2) of the Securities Act of 1933. Section 4(2) paper is restricted as to
disposition under federal securities laws in that any resale must similarly be
made in an exempt transaction. The Portfolios may or may not regard such
securities as illiquid, depending on the circumstances of each case.

         Any Portfolio may also invest in obligations (including certificates of
deposit, demand and time deposits and bankers' acceptances) of U.S. banks and
savings and loan institutions. While domestic bank deposits are insured by an
agency of the U.S. Government, the Portfolios will generally assume positions
considerably in excess of the insurance limits.

<PAGE>




                      LOAN PARTICIPATIONS AND ASSIGNMENTS
- --------------------------------------------------------------------------------

         The purchase of loan participations and assignments entails special
risks. A Portfolio's ability to receive payments of principal and interest and
other amounts in connection with loan participations and assignments will depend
primarily on the financial condition of the borrower. The failure by the
Portfolio to receive scheduled interest or principal payments on a loan
participation or assignment would adversely affect the income of the Portfolio
and would likely reduce the value of its assets. Because loan participations are
not generally rated by independent credit rating agencies, a decision by a
Portfolio to invest in a particular loan participation will depend almost
exclusively on its Adviser's credit analysis of the borrower. In addition to the
other risks associated with investments in debt securities, participations and
assignments involve the additional risk that the insolvency of any financial
institution interposed between the Portfolio and the borrower could delay or
prevent the flow of payments from the borrower on the underlying loan. A
Portfolio may have limited rights to enforce the terms of the underlying loan,
and the liquidity of loan participations and assignments may be limited.

         The borrower of a loan in which a Portfolio holds a participation
interest may, either at its own election or pursuant to terms of the loan
documentation, prepay amounts of the loan from time to time. There is no
assurance that the Portfolio will be able to reinvest the proceeds of any loan
prepayment at the same interest rate or on the same terms as those of the
original loan participation.

         Corporate loans in which a Portfolio may purchase a loan participation
or assignment are made generally to finance internal growth, mergers,
acquisitions, stock repurchases, leveraged buy-outs, and other corporate
activities. The highly leveraged capital structure of the borrowers in certain
of these transactions may make such loans especially vulnerable to adverse
changes in economic or market conditions.

         Certain of the loan participations or assignments acquired by a
Portfolio may involve unfunded commitments of the lenders or revolving credit
facilities under which a borrower may from time to time borrow and repay amounts
up to the maximum amount of the facility. In such cases, the Portfolio would
have an obligation to advance its portion of such additional borrowings upon the
terms specified in the loan documentation.

                    INDEXED SECURITIES AND STRUCTURED NOTES
- --------------------------------------------------------------------------------

         The values of indexed securities and structured notes are linked to
currencies, other securities, interest rates, commodities, indices or other
financial indicators ("reference instruments"). These instruments differ from
other types of debt securities in several respects. The interest rate or
principal amount payable at maturity may vary based on

                                      -47-




<PAGE>



changes in one or more specified reference instruments, such as a floating
interest rate compared with a fixed interest rate or the currency exchange rates
between two currencies (neither of which need be the currency in which the
instrument is denominated). An indexed security or structured note may be
positively or negatively indexed; that is, its value or interest rate may
increase or decrease if the value of the reference instrument increases.
Further, the change in the principal amount payable with respect to, or the
interest rate of, an indexed security or structured note may be a multiple of
the percentage change (positive or negative) in the value of the underlying
reference instrument(s).

         Investment in indexed securities and structured notes involves certain
risks, including the credit risk of the issuer and the normal risks of price
changes in response to changes in interest rates. Further, in the case of
certain indexed securities or structured notes, a decline in the reference
instrument may cause the interest rate to be reduced to zero, and any further
declines in the reference instrument may then reduce the principal amount
payable on maturity. Finally, these securities may be less liquid than other
types of securities, and may be more volatile than their underlying reference
instruments.

                              FORWARD COMMITMENTS
- --------------------------------------------------------------------------------

         Each Portfolio may enter into commitments to purchase securities on a
"forward commitment" basis, including purchases on a "when-issued" basis or a
"to be announced" basis. When such transactions are negotiated, certain terms
may be fixed at the time the commitment is made, but delivery and payment for
the securities takes place at a later date. Such securities are often the most
efficiently priced and have the best liquidity in the bond market. During the
period between a commitment and settlement, no payment is made by the purchaser
for the securities purchased and, thus, no interest accrues to the purchaser
from the transaction. In a "to be announced" transaction, a Portfolio commits to
purchase securities for which all specific information is not yet known at the
time of the trade, particularly the exact face amount in forward commitment
mortgage-backed securities transactions.

         A Portfolio may sell the securities subject to a forward commitment
purchase, which may result in a gain or loss. When a Portfolio purchases
securities on a forward commitment basis, it assumes the risks of ownership,
including the risk of price fluctuation, at the time of purchase, not at the
time of receipt. Purchases of forward commitment securities also involve a risk
of loss if the seller fails to deliver after the value of the securities has
risen. Depending on market conditions, a Portfolio's forward commitment
purchases could cause its net asset value to be more volatile.

         Each Portfolio may also enter into a forward commitment to sell
securities it owns and will generally do so only with the intention of actually
delivering the securities. The use of forward commitments enables a Portfolio to
hedge against anticipated changes in interest

                                      -48-




<PAGE>



rates and prices. In a forward sale, a Portfolio does not participate in gains
or losses on the security occurring after the commitment date. Forward
commitments to sell securities also involve a risk of loss if the seller fails
to take delivery after the value of the securities has declined.

         Forward commitment transactions involve additional risks similar to
those associated with investments in options and futures contracts. See "Options
and Futures Contracts." It is not expected that any Portfolio's purchases of
forward commitments will at any time exceed, in the aggregate, 20% of that
Portfolio's total assets.

                       RESTRICTED AND ILLIQUID SECURITIES
- --------------------------------------------------------------------------------

         Restricted securities are securities subject to legal or contractual
restrictions on their resale, such as private placements. Such restrictions
might prevent the sale of restricted securities at a time when the sale would
otherwise be desirable. No securities for which there is not a readily available
market ("illiquid securities") will be acquired by any Portfolio if such
acquisition would cause the aggregate value of illiquid securities to exceed 15%
of the Portfolio's net assets (10% of net assets for the Western Asset Money
Market Portfolio and the Western Asset Government Money Market Portfolio).

         Under SEC regulations, certain securities acquired through private
placements can be traded freely among qualified purchasers. The SEC has stated
that an investment company's board of directors, or its investment adviser
acting under authority delegated by the board, may determine that a security
eligible for trading under this rule is "liquid." The Portfolios intend to rely
on this rule, to the extent appropriate, to deem specific securities acquired
through private placement as "liquid." The Boards have delegated to a
Portfolio's Adviser the responsibility for determining whether a particular
security eligible for trading under this rule is "liquid." Investing in these
restricted securities could have the effect of increasing a Portfolio's
illiquidity if qualified purchasers become, for a time, uninterested in buying
these securities.

         Illiquid securities may be difficult to value, and a Portfolio may have
difficulty disposing of such securities promptly. The Portfolios do not consider
foreign securities to be restricted if they can be freely sold in the principal
markets in which they are traded, even if they are not registered for sale in
the U.S.

                    SECURITIES OF OTHER INVESTMENT COMPANIES
- --------------------------------------------------------------------------------

         Investments in other investment companies may involve the payment of
substantial premiums above the net asset value of such issuers' portfolio
securities, and the total return on such investments will be reduced by the
operating expenses and fees of such investment

                                      -49-




<PAGE>



companies, including advisory fees.  The Portfolios may invest in both
closed-end and open-end investment companies.

                             REPURCHASE AGREEMENTS
- --------------------------------------------------------------------------------

         A repurchase agreement is an agreement under which securities are
acquired from a securities dealer or bank subject to resale at an agreed upon
price and date. The securities are held by a Portfolio as collateral until
retransferred and will be supplemented by additional collateral if necessary to
maintain a total market value equal to or in excess of the value of the
repurchase agreement. The Portfolio bears a risk of loss in the event that the
other party to a repurchase agreement defaults on its obligations and the
Portfolio is delayed or prevented from exercising its rights to dispose of the
collateral securities. A Portfolio also bears the risk that the proceeds from
any sale of collateral will be less than the repurchase price.

               REVERSE REPURCHASE AGREEMENTS AND OTHER BORROWING
- --------------------------------------------------------------------------------

         A reverse repurchase agreement is a portfolio management technique in
which a Portfolio temporarily transfers possession of a portfolio instrument to
another person, such as a financial institution or broker-dealer, in return for
cash. At the same time, the Portfolio agrees to repurchase the instrument at an
agreed upon time (normally within seven days) and price, including interest
payment. While engaging in reverse repurchase agreements, each Portfolio will
maintain cash or securities in a segregated account at its custodian bank with a
value at least equal to the Portfolio's obligation under the agreements,
adjusted daily. Reverse repurchase agreements may expose a Portfolio to greater
fluctuations in the value of its assets and renders the segregated assets
unavailable for sale or other disposition.

         The Portfolios may also enter into dollar roll transactions in which a
Portfolio sells a fixed income security for delivery in the current month and
simultaneously contracts to purchase substantially similar (same type, coupon
and maturity) securities at an agreed upon future time. By engaging in the
dollar roll transaction the Portfolio foregoes principal and interest paid on
the security that is sold, but receives the difference between the current sales
price and the forward price for the future purchase. The Portfolio would also be
able to earn interest on the income that is received from the initial sale.

         Each Portfolio will limit its investments in reverse repurchase
agreements and other borrowing (including dollar roll transactions) to no more
than one-third of its total assets. To avoid potential leveraging effects of
such borrowing (including reverse repurchase agreements and dollar rolls), a
Portfolio will not make investments while its borrowing is in excess of 5% of
its total assets.

                                      -50-




<PAGE>




                         LOANS OF PORTFOLIO SECURITIES
- --------------------------------------------------------------------------------

         A Portfolio may lend its portfolio securities, provided that cash or
equivalent collateral, equal to at least 100% of the market value of the
securities loaned, is continuously maintained by the borrower with the
Portfolio. During the time securities are on loan, the borrower will pay the
Portfolio an amount equivalent to any dividends or interest paid on such
securities, and the Portfolio may invest the cash collateral and earn additional
income, or it may receive an agreed upon amount of interest income from the
borrower who has delivered equivalent collateral. These loans are subject to
termination at the option of the Portfolio or the borrower. A Portfolio may pay
administrative and custodial fees in connection with a loan and may pay a
negotiated portion of the interest earned on the cash or equivalent collateral
to the borrower or placing broker. No Portfolio presently expects to have on
loan at any given time securities totaling more than one-third of its net
assets. A Portfolio runs the risk that the counterparty to a loan transaction
will default on its obligation and that the value of the collateral received may
decline before the Portfolio can dispose of it.

                                    DURATION
- --------------------------------------------------------------------------------

         Duration is a measure of the expected life of a fixed income security
on a cash flow basis. Duration takes the time intervals over which the interest
and principal payments are scheduled and weights each by the present values of
the cash to be received at the corresponding future point in time. For any fixed
income security with interest payments occurring prior to the payment of
principal, duration is always less than maturity. For example, a current coupon
bond with a maturity of 3.5 years will have a duration of approximately three
years. In general, the lower the stated or coupon rate of interest of a fixed
income security, the longer its duration; conversely, the higher the stated or
coupon rate of interest of a fixed income security, the shorter its duration.

                               PORTFOLIO TURNOVER
- --------------------------------------------------------------------------------

         The turnover rates of the Western Asset Limited Duration Portfolio, the
Western Asset Intermediate Portfolio and the Western Asset Core Portfolio for
the nine month period ended March 31, 1998 on an annualized basis were 373%,
401.4% and 226.9%, respectively. While it is impossible to predict portfolio
turnover rates, the Western Asset Enhanced Equity Portfolio, the Western Asset
Intermediate Plus Portfolio, the Western Asset Core Plus Portfolio, the Western
Asset High Yield Portfolio, the Western Asset Non-U.S. Fixed Income Portfolio
and the Western Asset Global Strategic Income Portfolio expect that their
average turnover rate will not exceed 400%, 400%, 400%, 200%, 200% and 200%,
respectively.

         The length of time a Portfolio has held a particular security is not
generally a consideration in investment decisions. A change in the securities
held by a Portfolio is known as "portfolio turnover." As a result of a
Portfolio's investment policies, under certain market conditions a Portfolio's
portfolio turnover rate may be higher than that of other mutual funds. Portfolio
turnover generally involves some expense to a Portfolio, including brokerage
commissions or dealer mark-ups and other transaction costs on the sale of
securities and reinvestment in other securities. These transactions may result
in realization of taxable capital gains. Higher portfolio turnover rates, such
as those above 100%, are likely to result in higher brokerage commissions or
other transactions costs and could give rise to a greater amount of taxable
capital gains.

                       ALTERNATIVE INVESTMENT STRATEGIES
- --------------------------------------------------------------------------------

         At times a Portfolio's Adviser may judge that conditions in the
securities markets make pursuing the Portfolio's typical investment strategy
inconsistent with the best interests of its shareholders. At such times, the
Adviser may temporarily use alternative strategies, primarily designed to reduce
fluctuations in the value of the Portfolio's assets. In implementing these
defensive strategies, a Portfolio may invest without limit in a variety of
securities that the Adviser believes present less risk to a Portfolio, including
equity securities, debt securities, preferred stocks, U.S. Government and agency
obligations, cash or money market instruments, or in other securities the
Adviser considers consistent with such defensive strategies. It is impossible to
predict when, or for how long, a Portfolio will use these alternative
strategies.

                            NEW INVESTMENT PRODUCTS
- --------------------------------------------------------------------------------

         New types of mortgage-backed and asset-backed securities, derivative
instruments and hedging instruments are developed and marketed from time to
time. Consistent with its investment limitations, each Portfolio expects to
invest in those new types of securities and instruments that its Adviser
believes may assist the Portfolio in achieving its investment objective.

                              INVESTMENT POLICIES
- --------------------------------------------------------------------------------

         The investment objective of each of the Western Asset Core, the Western
Asset Limited Duration, the Western Asset Intermediate and the Western Asset
Money Market Portfolio are "fundamental." Except for investment policies
designated as fundamental in this prospectus or the SAI, the investment policies
described in this prospectus and in the SAI are not fundamental policies.
Changes to fundamental investment policies require shareholder approval; the
Directors may change any non-fundamental investment policy without shareholder
approval.

PERFORMANCE DATA
- --------------------------------------------------------------------------------

         Advertisements and other communications to shareholders or prospective
investors may include performance information about a Portfolio. "Yield" for
each class of shares of a Portfolio (other than the Western Asset Money Market
Portfolio and the Western Asset Government Money Market Portfolio) is calculated
by dividing the annualized net investment income per share during a recent
30-day period by the maximum public offering price per share of the class on the
last day of that period. Yield for the Western Asset Money Market Portfolio and
the Western Asset Government Money Market Portfolio is derived from the income
generated by an investment in a Portfolio over a stated seven-day period. This
income is "annualized," i.e., the average daily net income generated by the
investment during that week is assumed to be generated each day over a 365-day
period, and is shown as a percentage of the investment. "Effective yield" is
calculated similarly but assumes that the income earned by an investment is
reinvested.

         "Total return" is a measurement of the overall change in value,
including changes in share price and assuming reinvestment of distributions, of
an investment in a Portfolio. "Cumulative total return" shows a Portfolio's
performance over a specific period of time. "Average annual total return" for
the one-, five- and ten-year periods (or for the life of a class, if shorter)
through the most recent calendar quarter represents the average annual
compounded rate of return on an investment of $1,000 in a Portfolio invested at
the maximum public offering price.

         Investment performance, which will vary, is based on many factors,
including market conditions, portfolio composition, Portfolio operating expenses
and the class of shares the investor purchases. Investment performance also
often reflects the risks associated with a Portfolio's investment objective and
policies. These factors should be considered when comparing a Portfolio's
investment results with those of other mutual funds and other investment
vehicles. Performance information is based on historical performance and should
not be viewed as representative of a Portfolio's future performance. The
investment return and principal value of an investment in a Portfolio (other
than the Western Asset Money Market Portfolio and the Western Asset Government
Money Market Portfolio, which attempt to maintain a stable net asset value per
share) will fluctuate so that an investor's shares, when redeemed, may be worth
more or less than their original cost.

         Quotations of investment performance for any period when an expense
limitation was in effect will be greater than if the limitation had not been in
effect. Portfolio performance may be compared to that of various indexes. See
the SAI.

                               BOARD OF DIRECTORS
- --------------------------------------------------------------------------------

         The business affairs of the Corporation are managed under the direction
of a Board of Directors, and the Directors of the Corporation are responsible

about the Directors and executive officers of the Corporation may be found in
the SAI.

         The Board of Directors has retained the Manager and the Advisers to
manage the Portfolios' affairs, furnish a continuing investment program for the
Portfolios and make investment decisions on their behalf, subject to such
policies as the Directors may determine.

                    MANAGER, ADVISERS AND PORTFOLIO MANAGERS
- --------------------------------------------------------------------------------

         The Portfolios are managed by the Manager. Each Portfolio pays the

of their respective investment strategy groups.

                                  DISTRIBUTORS
- --------------------------------------------------------------------------------

         Legg Mason Wood Walker, Incorporated ("Legg Mason") is the distributor
of each Portfolio's shares. Legg Mason pays certain expenses in connection with
the offering of shares of each Portfolio, including any compensation to its
financial advisors, the printing and distribution of prospectuses, SAIs and
periodic reports used in connection with the offering to prospective investors,
and expenses relating to any supplementary sales literature or advertising. The
Portfolios bear the expenses of preparing, setting in type and mailing the
prospectuses, SAIs and periodic reports to existing shareholders.

         Arroyo Seco, Inc. ("Arroyo Seco"), a wholly owned subsidiary of Western
Asset, is also authorized to offer the Portfolios' shares for sale to its
customers. The Portfolios make no payments to Arroyo Seco in connection with the
offer or sale of their shares, and Arroyo Seco does not collect any commissions
or other fees from customers in connection with the offer or sale of the
Portfolios' shares.

                             PORTFOLIO TRANSACTIONS
- --------------------------------------------------------------------------------

         Each Portfolio's Adviser places all orders for the purchase and sale of
portfolio investments with brokers or dealers selected by it in its discretion.
It will seek the best price and execution of each Portfolio's orders. However,
the Adviser may pay higher commission rates than the lowest available when it
believes it is reasonable to do so in light of the value of brokerage and
research services provided by the broker effecting the transaction. The Adviser
may also consider sales of shares of the Portfolio (or other Portfolios or other
funds managed by it or its affiliates, to the extent permitted by applicable
law) in selecting broker-dealers to execute Portfolio transactions.

         Some securities considered by an Adviser for purchase by a Portfolio
may also be appropriate for other clients served by the Adviser. Transactions in
such securities will be allocated among the Portfolios and such other clients in
a manner considered fair and reasonable by the Adviser.

                                    EXPENSES
- --------------------------------------------------------------------------------

         Each Portfolio pays its share of all expenses of the Corporation that
are not assumed by the Manager, the relevant Adviser or other parties, including
Directors', auditing, legal, custodial, transfer agency and distribution fees
(which are in turn allocated to the Financial Intermediary Class of shares).

ORGANIZATION AND HISTORY
- --------------------------------------------------------------------------------

         LM Institutional Fund Advisors I, Inc. ("LM Institutional I") was
incorporated in Maryland on May 16, 1990. Prior to May 29, 1998, LM
Institutional I was known as "Western Asset Trust, Inc." Each Portfolio is an
open-end, diversified management company, except for Western Asset Non-U.S.
Fixed Income Portfolio and Western Asset Global Strategic Income Portfolio,
which are non-diversified companies. The Directors of the Corporation may,
without shareholder approval, create, in addition to the Portfolios, other
series of shares representing separate investment portfolios. Any such series
may be divided without shareholder approval into two or more classes of shares
having such terms as the Directors may determine.

         The Corporation has a total of 13.1 billion shares of common stock at
par value $0.001. Each share has one vote, with fractional shares voting
proportionally. Voting on matters pertinent only to a particular Portfolio, such
as the adoption of an investment advisory contract for that Portfolio, is
limited to that Portfolio's shareholders. Shares of all classes of a Portfolio
will vote together as a single class except when otherwise required by law or as
determined by the Directors. Shares are freely transferable, are entitled to

                                      -57-




<PAGE>



dividends as declared by the Directors, and, if a Portfolio were liquidated,
would receive the net assets of that Portfolio. Voting rights are not
cumulative, and all shares of the Portfolios are fully paid and nonassessable
and have no preemptive or conversion rights.

         Although no Portfolio intends to hold annual shareholder meetings, it
will hold a special meeting of shareholders when the Investment Company Act of
1940 (the "1940 Act") requires a shareholder vote on certain matters (including
the election of Directors in certain cases or approval of an advisory contract).

PURCHASE OF SHARES
- --------------------------------------------------------------------------------

         The Portfolios offer two classes of shares:  Institutional Class and
Financial Intermediary Class.  Shares in the Financial Intermediary Class bear a
12b-1 fee. See "Distribution Plans" below for more information.

                               INITIAL INVESTMENT
- --------------------------------------------------------------------------------

         Prior to or concurrent with the initial purchase of shares in any
Portfolio, each investor must open an account for that Portfolio by completing
and signing an Application and mailing it to Boston Financial Data Services (the
"Transfer Agent" or "BFDS") at the following address: P.O. Box 953, Boston,
Massachusetts 02103. In general, an investor must make a minimum initial
investment of $1,000,000 to open an account in any Portfolio. Thereafter, there
is no minimum for subsequent investments. The Portfolios reserve the right to
change the minimum requirements at their discretion. An employee benefit or
retirement plan is not subject to the minimum investment requirement provided
the plan has more than $5,000,000 in assets.

         A purchase order, together with payment in proper form, received by the
Transfer Agent prior to the close of regular trading on the Exchange (ordinarily
4:00 p.m., Eastern time) ("close of the Exchange") will be effected at that
day's net asset value. An order received after the close of the Exchange will
generally be effected at the net asset value determined on the next business
day. However, orders received by certain retirement plans and other financial
intermediaries by the close of the Exchange and communicated to the Transfer
Agent by 9:00 a.m., Eastern time, on the following business day will be effected
at the net asset value determined on the prior business day.

         Purchases of shares can be made by wiring federal funds to State Street
Bank and Trust Company. Purchases of shares of the Western Asset Money Market
Portfolio or the Western Asset Government Money Market Portfolio may ONLY by
made by federal funds wire. Before wiring federal funds, the investor must first
telephone the Portfolio at (626) 844-9400 to receive instructions for wire
transfer. On the telephone, the following

                                      -58-




<PAGE>



information will be required: shareholder name; name of the person authorizing
the transaction; shareholder account number; name of the Portfolio and class of
shares to be purchased; amount being wired; and name of the wiring bank.

         Funds should be wired through the Federal Reserve System to:

                  State Street Bank and Trust Company
                  ABA #011-000-028
                  LM Institutional Fund Advisors [insert name of Portfolio]
                  [Insert your account name and number]

         The wire should state that the funds are for the purchase of shares of
a specific Portfolio and include the account name and number. With respect to
Portfolios whose policy is to declare dividends daily, if a purchase order for
shares is received prior to 12:00 noon, Eastern time, and payment in federal
funds is received by the Transfer Agent by the close of the federal funds wire
on the day the purchase order is received, dividends will accrue starting that
day. If a purchase order is received after 12:00 noon, Eastern time, and payment
in federal funds is received by the Transfer Agent by the close of the federal
funds wire on the day the purchase order is received, or as otherwise agreed to
by the relevant Portfolio, the order will be effected at that day's net asset
value, but dividends will not begin to accrue until the following business day.

         Shares may also be purchased and paid for by the contribution of
eligible portfolio securities, subject in each case to approval by the Manager.
Approval will depend on, among other things, the nature and quality of the
securities offered and the current needs of the Portfolio in question.
Securities offered in payment for shares will be valued in the same way and at
the same time the Portfolio values it portfolio securities for purposes of
determining net asset value. See "How Each Portfolio Values Its Shares," below.
Investors who wish to purchase Portfolio shares through the contribution of
securities should contact the Portfolio at (626) 844-9400 for instructions.
Investors should also realize that at the time of contribution they may be
required to recognize a gain or loss for tax purposes on securities contributed.
The Portfolio has full discretion to reject any securities offered as payment
for shares. As described below, each Portfolio may offer Financial Intermediary
Class shares that are offered primarily through financial intermediaries. Each
Portfolio may pay financial intermediaries for their services out of that
class's assets pursuant to the class's distribution plan or otherwise. Legg
Mason and its affiliates (including the Manager and the Advisers) may also from
time to time, at their own expense, make payments to financial intermediaries
that sell shares of the Portfolios or to other parties in connection with the
sale of shares. If investors effect transactions through a broker or agent,
investors may be charged a fee by that broker or agent.

         Any shares purchased or received as a distribution will be credited
directly to the investor's account.

                                      -59-




<PAGE>




                             ADDITIONAL INVESTMENTS
- --------------------------------------------------------------------------------

         Additional investments may be made at any time at the relevant net
asset value for that class by following the procedures outlined above. Investors
should always furnish a shareholder account number when making additional
purchases.

                           OTHER PURCHASE INFORMATION
- --------------------------------------------------------------------------------

         Purchases will be made in full and fractional shares. In the interest
of economy and convenience, certificates for shares will not be issued.

         Each Portfolio and Distributor reserves the right, in its sole
discretion, to suspend the offering of shares or to reject any purchase order,
in whole or in part, when, in the judgment of management, such suspension or
rejection is in the best interests of the Portfolio; to waive the minimum
initial investment for certain investors; and to redeem shares if information
provided in the Application should prove to be incorrect in any manner judged by
a Portfolio to be material (e.g., in a manner such as to render the shareholder
ineligible to purchase shares of a Portfolio). A Portfolio may suspend the
offering of shares at any time and resume it at any time thereafter.

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

         Purchases and sales of Portfolio shares should be made for long-term
investment purposes only. Each Portfolio reserves the right to restrict
purchases of shares (including exchanges) when a pattern of frequent purchases
and sales made in response to short-term fluctuations in share price appears
evident.

                                RETIREMENT PLANS
- --------------------------------------------------------------------------------

         Shares of the Portfolios are available for purchase by retirement
plans, including 401(k) plans, 403(b) plans and Individual Retirement Accounts
("IRAs"). The administrator of a plan or employee benefits office can provide
participants or employees with detailed information on how to participate in the
plan and how to elect a Portfolio as an investment option. Participants in a
retirement or savings plan may be permitted to elect different investment
options, alter the amounts contributed to the plan, or change how contributions
are allocated among investment options in accordance with the plan's specific
provisions. The plan administrator or employee benefits office should be
consulted for details. For

                                      -60-




<PAGE>



questions about participant accounts, participants should contact their employee
benefits office, the plan administrator, or the organization that provides
recordkeeping services for the plan. Investors who purchase shares through
retirement plans should be aware that the plan administrator may aggregate
purchase and redemption orders of participants in the plan. Therefore, there may
be a delay between the time the investor places an order with the plan
administrator and the time the order is forwarded to the Transfer Agent for
execution.

                          ACCOUNT REGISTRATION CHANGES
- --------------------------------------------------------------------------------

         Changes in registration or account privileges may be made in writing to
the Transfer Agent.  Signature guarantees may be required.  See "Signature
Guarantee" below.  All correspondence must include the account number and must
be sent to:

         Boston Financial Data Services
         P.O. Box 953
         Boston, Massachusetts,  02103

DISTRIBUTION PLANS
- --------------------------------------------------------------------------------

         The Board of Directors has adopted Distribution Plans pursuant to Rule
12b-1 under the 1940 Act with respect to shares of the Financial Intermediary
Class of each Portfolio. Under the terms of each Plan, a Portfolio is permitted
to pay, out of the assets of the Financial Intermediary Class of the Portfolio,
in an amount up to 0.40% on an annual basis of the average daily net assets of
that class, financial intermediaries and other parties that provide services in
connection with the distribution of shares or administration of plans or
programs that use Portfolio shares as their funding medium, and to reimburse
certain other distribution-related expenses. Payments under the Plans are
currently limited to an annual rate of .25% of average daily net assets (.10%
for the Western Asset Money Market Portfolio and the Western Asset Government
Money Market Portfolio). For more information regarding the Plans and their
terms, see the SAI.

REDEMPTION OF SHARES
- --------------------------------------------------------------------------------


         Portfolio shares may be redeemed through three methods: (1) by sending
a written request for redemption to the Transfer Agent at P.O. Box 953, Boston,
Massachusetts, 02103; (2) by calling the Portfolio at (626) 844-9400; or (3) by
wire communication with the Transfer Agent. In each case, the investor should
first notify the Portfolio at (626) 844-9400 of the intention to redeem. No
charge is made for redemptions. Shareholders who wish to be able to redeem by
telephone or wire communication must complete an authorization form in advance.
Redemptions over $10,000,000 may be initiated by telephone, but must be
confirmed in writing prior to processing. With respect to telephone redemptions
or transfers,

                                      -61-

the Transfer Agent will process orders based on instructions from a shareholder,
or any person claiming to act as his or her representative, who can provide it
with his or her account registration and address as it appears on its records.
The Transfer Agent will employ these and other reasonable procedures to confirm
that instructions communicated by telephone are genuine; if it fails to employ
reasonable procedures, the Transfer Agent may be liable for any losses due to
unauthorized or fraudulent instructions.

         Upon receipt of a request in good order for redemption before the close
of the Exchange on any day when the Exchange is open, the Transfer Agent will
redeem Portfolio shares at that day's net asset value per share. Requests for
redemption received by the Transfer Agent after the close of the Exchange will
be executed at the net asset value next determined. The Portfolios may refuse to
effect redemption requests during periods permitted by the federal securities
laws.

         Requests for redemption should indicate:

         1. The number of shares or dollar amount to be redeemed and the
investor's shareholder account number;

         2. The investor's name and the names of any co-owner of the account,
using exactly the same name or names used in establishing the account;

         3. Proof of authorization to request redemption on behalf of any
co-owner of the account (please contact BFDS or the Portfolio for further
details); and

         4. The name, address, and account number to which the redemption
payment should be sent.

         Payment of the redemption price normally will be made by wire three
business days after receipt of a redemption request in good order. However, each
Portfolio reserves the right to postpone the payment date when the Exchange is
closed, when trading is restricted, or during other periods as permitted by
federal securities laws, or to take up to seven days to make payment upon
redemption if the Portfolio involved could be adversely affected by immediate
payment. Redemption proceeds may also be paid in kind at the discretion of the
Portfolio. Shareholders who receive a redemption in kind may incur costs to
dispose of such securities.

         Shareholders of some investment companies have experienced difficulty
contacting their funds by telephone during periods of intense market activity.
Shareholders who are unable to contact a Portfolio by telephone and wish to make
a redemption should follow the instructions for redeeming by mail or by wire.

                                      -62-




<PAGE>



         Other supporting legal documents, such as copies of the trust
instrument or power of attorney, may be required from corporations or other
organizations, fiduciaries or persons other than the shareholder of record
making the request for redemption or repurchase. If you have a question
concerning the sale or redemption of shares, please contact the Portfolio or the
Transfer Agent.

         Any Portfolio may elect to close any shareholder account with a current
value of less than $1 million by redeeming all of the shares in the account and
mailing the proceeds to the investor. If a Portfolio elects to redeem the shares
in an account, the shareholder will be notified that the account is below $1
million and will be allowed 30 days in which to make an additional investment in
order to avoid having the account closed. Shares will be redeemed at the net
asset value calculated on the day of redemption. Any Portfolio may change the $1
million minimum account balance from time to time without notice to
shareholders.

                              SIGNATURE GUARANTEE
- --------------------------------------------------------------------------------

         When a signature guarantee is called for, the shareholder should have
"Signature Guaranteed" stamped under his signature and guaranteed by any of the
following entities: U.S. banks, foreign banks having a U.S. correspondent bank,
credit unions, savings associations, U.S. registered dealers and brokers,
municipal securities dealers and brokers, government securities dealers and
brokers, national securities exchanges, registered securities associations and
clearing agencies (each an "Eligible Guarantor Institution"). Each Portfolio and
its agents reserve the right to reject any signature guarantee pursuant to
written signature guarantee standards or procedures, which may be revised in the
future to permit them to reject signature guarantees from Eligible Guarantor
Institutions that do not, based on credit guidelines, satisfy such written
standards or procedures. Any Portfolio may change the signature guarantee
requirements from time to time without prior notice to shareholders.

EXCHANGE PRIVILEGE
- --------------------------------------------------------------------------------

         Shareholders in any Portfolio may exchange their shares for shares of
the same class of any of the other Portfolios or of any of the portfolios
offered by LM Institutional Fund Advisors II, Inc., provided that the shares of
that class are being offered at the time of the proposed exchange. Investments
by exchange are made at the per share net asset values next determined after the
order for exchange is received in good order.

         The exchange privilege is not intended as a vehicle for short-term
trading. Excessive exchange activity may interfere with portfolio management and
have an adverse effect on all shareholders. In order to limit excessive exchange
activity and in other circumstances where a Portfolio believes doing so would be
in its best interest, the Portfolio reserves the right to revise or terminate
the exchange privilege, limit the amount or number of exchanges or reject

                                      -63-




<PAGE>



any exchange. For further information concerning the exchange privilege, or to
make an exchange, please contact the Portfolio at Boston Financial Data
Services, (626) 844-9400.

NET ASSET VALUE
- --------------------------------------------------------------------------------

         Net asset value per share of each class of shares is determined daily
for each Portfolio as of the close of regular trading on the Exchange (normally
4:00 p.m., Eastern time), on every day that the Exchange is open, by subtracting
the Portfolio's liabilities attributable to a given class of shares from its
total assets attributable to the class and dividing the result by the number of
shares of that class outstanding. Net asset value will not be determined on days
on which the Exchange is closed.

         Except for the Western Asset Money Market Portfolio and the Western
Asset Government Money Market Portfolio, portfolio securities and other assets
for which market quotations are readily available are valued at current market
value. Current market value means the last sale price of the day for a
comparable position, or, in the absence of any such sales, the mean between
representative bid and asked prices obtained from a quotation reporting system.
Securities with remaining maturities of 60 days or less are generally valued at
amortized cost. Fixed income securities, including those to be purchased under
firm commitment agreements, are normally valued on the basis of quotations
obtained from brokers and dealers or pricing services which take into account
appropriate factors such as institutional-size trading in similar groups of
securities, yield, quality, coupon rate, maturity, type of issue, trading
characteristics and other market data. Certain fixed income securities for which
daily market quotations are not readily available may be valued with reference
to fixed income securities whose prices are more readily available and whose
durations are comparable to those of the securities being valued.

         Other assets and securities for which no quotations are readily
available are valued at fair value as determined in good faith by the Directors
or persons acting at their direction. The values of foreign securities quoted in
foreign currencies are translated into U.S. dollars at current exchange rates or
at such other rates as the Directors or persons acting at their direction may
determine in computing net asset value.

         Because of time zone differences, foreign exchanges and securities
markets will usually be closed prior to the time of the closing of the Exchange
and values of foreign investments will be determined as of the earlier closing
of such exchanges and securities markets. However, events affecting the values
of such foreign securities may occasionally occur between the earlier closings
of such exchanges and securities markets and the closing of the Exchange which
will not be reflected in the computation of the net asset value. If an event
materially affecting the value of such foreign securities occurs during such
period, then such securities will be valued at fair value as determined in good
faith by the Directors or persons acting at their direction.

                                      -64-




<PAGE>



         The Western Asset Money Market Portfolio and the Western Asset
Government Money Market Portfolio each attempts to maintain a per share net
asset value of $1.00 by using the amortized cost method of valuation as
permitted by SEC Rule 2a-7. Neither Portfolio can guarantee that the net asset
value will always remain at $1.00 per share.

DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS
- --------------------------------------------------------------------------------

         The Western Asset Money Market Portfolio and the Western Asset
Government Money Market Portfolio declare as a dividend at the close of regular
trading on the Exchange each business day, to shareholders of record as of 12:00
noon, Eastern Time, that day, substantially all of their net investment income
since the prior business day's dividend. The Western Asset Money Market
Portfolio and the Western Asset Government Money Market Portfolio pay dividends
monthly. The other Portfolios declare and pay dividends quarterly out of their
net investment income for that quarter. Distributions of net realized capital
gains are made annually.

         Shareholders may elect to receive dividends and distributions in one of
four ways:

                  1)  Receive both dividends and other distributions in shares
                      of the same class of the distributing Portfolio;

                  2)  Receive dividends in cash and other distributions in
                      shares of the same class of the distributing Portfolio;

                  3)  Receive dividends in shares of the same class of the
                      distributing Portfolio and other distributions in cash; or

                  4)  Receive both dividends and other distributions in cash.

         If no election is made, both dividends and other distributions are
credited to a shareholder's Portfolio account in shares (of the same class as
the shares already held) at the net asset value of the shares determined as of
the close of the Exchange on the reinvestment date.

         For the Western Money Market Portfolio and the Western Asset Government
Money Market Portfolio, reinvestment of dividends and other distributions occurs
on the payment date. A shareholder who redeems all shares in the Western Asset
Money Market Portfolio or the Western Asset Government Money Market Portfolio
will receive all dividends and other distributions declared for that month cycle
prior to the redemption date (i.e., all dividends and other distributions from
the first day of that monthly cycle, if invested on that first day, to the date
of the redemption). For the other Portfolios, reinvestment occurs on the ex-
dividend date. An election to receive dividends or other distributions in cash
rather than

                                      -65-




<PAGE>



additional shares may be made by notifying the Transfer Agent in writing. The
election must be received at least ten days before the payment date in order to
be effective for distributions paid as of that date.

         If a shareholder has elected to receive dividends and/or other
distributions in cash and the postal or other delivery service is unable to
deliver checks to the shareholder's address of record, such shareholder's
distribution option will automatically be converted to having all dividends and
other distributions reinvested in additional shares. No interest will accrue on
amounts represented by uncashed distribution or redemption checks.

         The Directors reserve the right to revise the dividend policy or
postpone the payment of dividends if warranted in their judgment due to unusual
circumstances, such as an unexpected large expense, loss or fluctuation in net
asset value.

TAX INFORMATION
- --------------------------------------------------------------------------------

         Each Portfolio intends to qualify as a "regulated investment company"
for federal income tax purposes and to meet all other requirements necessary for
it to be relieved of federal taxes on income and gains it distributes to
shareholders. Each Portfolio will distribute substantially all its net
investment income and net realized capital gains to its shareholders on a
current basis.

         Distributions from a Portfolio (whether paid in cash or reinvested in
shares of the Portfolio) will be taxable to shareholders (other than IRAs, other
qualified retirement plans and other tax-exempt investors) as ordinary income to
the extent derived from the Portfolio's investment income and net short-term
gains. Shareholders will be taxable on distributions of net capital gains (that
is, the excess of net gains from capital assets held for more than one year over
net losses from capital assets held for not more than one year) at two different
tax rates pursuant to the Taxpayer Relief Act of 1997. One rate (generally 28%)
applies to net gains on capital assets held for more than one year but not more
than 18 months ("mid-term gains") and a second, preferred rate (generally 20%)
applies to the balance of such net capital gains ("adjusted net capital gains").
Distributions of net capital gains will be treated in the hands of shareholders
as mid-term gains to the extent designated by a Portfolio as deriving from net
gains from assets held for more than one year but not more than 18 months, and
the balance will be treated as adjusted net capital gains. Distributions of
mid-term gains and adjusted net capital gains will be taxable to shareholders as
such, regardless of how long a shareholder has held the shares in a Portfolio.

         Special tax rules apply to investments through defined contributions
plans and other tax-qualified plans. Shareholders should consult their tax
adviser to determine the suitability of shares of a Portfolio as an investment
through such plans and the precise effect of an investment on their particular
tax situation.

                                      -66-




<PAGE>



         To the extent distributions consist of interest from securities of the
U.S. Government and certain of its agencies and instrumentalities, they may be
exempt from state and local income taxes. Interest from obligations that are
merely guaranteed by the U.S. Government or one of its agencies, such as
mortgage participation certificates guaranteed by GNMA, generally is not
entitled to this exemption. Although there is no assurance that any such state
and local exemptions will be available, shareholders will be advised of the
portion of Portfolio distributions that might qualify for such an exemption.

         A Portfolio's investments in foreign securities may be subject to
withholding taxes at the source on dividend or interest payments. In that case,
a Portfolio's yield on those securities would be decreased.

         If at the end of a Portfolio's fiscal year more than 50% of the value
of its total assets represents securities of foreign corporations, the Portfolio
may make an election to treat any foreign taxes paid by it as paid by its
shareholders. In this case, shareholders who are U.S. citizens, U.S.
corporations and, in some cases, U.S. residents generally will be required to
include in U.S. taxable income their pro rata share of such taxes, but may then
generally be entitled to claim a foreign tax credit or deduction (but not both)
for their share of such taxes. A shareholder's ability to claim a foreign tax
credit or deduction in respect of foreign taxes paid by a Portfolio may be
subject to certain limitations (including a holding period requirement,
applicable to both a Portfolio and its shareholders, imposed by the Taxpayer
Relief Act of 1997).

         A Portfolio's transactions in foreign currencies and hedging activities
may give rise to ordinary income or loss to the extent such income or loss
results from fluctuations in value of the foreign currency concerned. In
addition, such activities will likely produce a difference between book income
and taxable income. This difference may cause a portion of a Portfolio's income
distributions to constitute a return of capital for tax purposes or require a
Portfolio to make distributions exceeding book income to qualify as a regulated
investment company for tax purposes.

         Investment in an entity that qualifies as a "passive foreign investment
company" under the Code could subject a Portfolio to a U.S. federal income tax
or other charge on certain "excess distributions" with respect to the
investment, and on the proceeds from disposition of the investment.

         Early each year each Portfolio will notify its shareholders of the
amount and tax status of distributions paid during that year.

         The foregoing is a summary of certain federal income tax consequences
of investing in a Portfolio. Shareholders are urged to consult their tax
advisers with respect to the effects of this investment on their particular tax
situation (including possible liability for state and local taxes).

APPENDIX  A  --  SECURITIES  RATINGS
- --------------------------------------------------------------------------------

The following rating services describe rated securities as follows:

MOODY'S INVESTORS SERVICE, INC.

BONDS

Aaa -- Bonds which are rated Aaa are judged to be of the best quality. They
carry the smallest degree of investment risk and are generally referred to as
"gilt edged." Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change, such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.

Aa -- Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they compromise 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
which make the long-term risk appear somewhat larger than the Aaa securities.

A -- Bonds which are rated A possess many favorable investment attributes and
are to be considered as upper-medium grade obligations. Factors giving security
to principal and interest are considered adequate, but elements may be present
which suggest a susceptibility 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 elements; their
future cannot be considered as well-assured. Often the protection of interest
and principal payments may be very moderate, and thereby not well safeguarded
during both good and bad times over the future. Uncertainty of position
characterizes bonds in this class.

B -- Bonds which are rated B generally lack characteristics of the desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.



                                      A-1


<PAGE>



Caa -- Bonds which are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal or
interest.

Ca -- Bonds 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 prospects of ever attaining any
real investment standing.

NOTES

MIG 1/VMIG 1 -- This designation denotes best quality. There is present strong
protection by established cash flows, superior liquidity support or demonstrated
broad-based access to the market for refinancing.

MIG 2/VMIG 2 -- This designation denotes high quality. Margins of protection are
ample although not so large as in the preceding group.

COMMERCIAL PAPER

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 the following characteristics:

- --       Leading market positions in well established industries.
- --       High rates of return on funds employed.
- --       Conservative capitalization structure with moderate
         reliance on debt and ample asset protection.
- --       Broad margins in earnings coverage of fixed financial
         charges and high internal cash generation.
- --       Well established access to a range of financial markets
         and assured sources of alternate liquidity.

Issuers rated PRIME-2 (or supporting institutions) have a strong ability for
repayment of senior short-term debt obligations. This will normally be evidenced
by many of the characteristics cited above 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.



                                      A-2


<PAGE>



STANDARD & POOR'S

BONDS

AAA -- Debt rated "AAA" has the highest rating assigned by Standard & Poor's.
Capacity to pay interest and repay principal is extremely strong.

AA -- Debt rated "AA" has a very strong capacity to pay interest and repay
principal and differs from the higher rated issues only in small degree.

A -- Debt rated "A" has a strong capacity to pay interest and repay principal
although it is somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions than debt in higher rated categories.

BBB -- Debt rated "BBB" is regarded as having an adequate capacity to pay
interest and repay principal. Whereas it normally exhibits adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than in higher rated categories.

BB-B-CCC-CC-C -- Debt rated "BB", "B", "CCC", "CC" and "C" is regarded, on
balance, as predominantly speculative with respect to capacity to pay interest
and repay principal in accordance with the terms of the obligation. "BB"
indicates the lowest degree of speculation and "C" the highest. While such debt
will likely have some quality and protective characteristics, these are
outweighed by large uncertainties or major exposures to adverse conditions.

BB -- Debt rated "BB" has less near-term vulnerability to default than other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse business, financial, or economic conditions which could lead to
inadequate capacity to meet timely interest and principal payments. The "BB"
rating category is also used for debt subordinated to senior debt that is
assigned an actual or implied "BBB" rating.

B -- Debt rated "B" has a greater vulnerability to default but currently has the
capacity to meet interest payments and principal repayments. Adverse business,
financial, or economic conditions will likely impair capacity or willingness to
pay interest and repay principal. The "B" rating category is also used for debt
subordinated to senior debt that is assigned an actual or implied "BB" or "BB-"
rating.

CCC -- Debt rated "CCC" has a currently identifiable vulnerability to default,
and is dependent upon favorable business, financial, and economic conditions to
meet timely payment of interest and repayment of principal. In the event of
adverse business, financial, or economic conditions, it is not likely to have
the capacity to pay interest and repay



                                      A-3


<PAGE>



principal. The "CCC" rating category is also used for debt subordinated to
senior debt that is assigned an actual or implied "B" or "B-" rating.

CC -- The rating "CC" typically is applied to debt subordinated to senior debt
that is assigned an actual or implied "CCC" rating.

C -- The rating "C" typically is applied to debt subordinated to senior debt
which is assigned an actual or implied "CCC-" debt rating. The "C" rating may be
used to cover a situation where a bankruptcy petition has been filed, but debt
service payments are continued.

D -- Bonds rated "D" are 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 also will be used
on the filing of a bankruptcy petition if debt service payments are jeopardized.

NOTES

SP-1 -- Strong capacity to pay principal and interest. Those issues determined
to possess overwhelming safety characteristics are given a plus (+) designation.

SP-2 -- Satisfactory capacity to pay principal and interest.

SP-3 -- Speculative capacity to pay principal and interest.

COMMERCIAL PAPER

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 designation is
satisfactory. However, the relative degree of safety is not as high as for
issues designated "A-1."

A-3 -- Issues carrying this designation have adequate capacity for timely
payment. They are, however, more vulnerable to the adverse effects of changes in
circumstances than obligations carrying the higher designations.

FITCH INVESTORS SERVICE, INC.

AAA -- Bonds considered to be investment grade and of the highest credit
quality. The obligor has an exceptionally strong ability to pay interest and
repay principal, which is unlikely to be affected by reasonably foreseeable
events.



                                      A-4


<PAGE>



AA -- Bonds considered to be investment grade and of very high credit quality.
The obligor's ability to pay interest and repay principal is very strong,
although not quite as strong as bonds rated AAA.

A -- Bonds considered to be investment grade and of high credit quality. The
obligor's ability to pay interest and repay principal is considered to be
strong, but may be more vulnerable to adverse changes in economic conditions and
circumstances than bonds with higher ratings.

BBB -- Bonds considered to be investment grade and of satisfactory credit
quality. The obligor's ability to pay interest and repay principal is considered
to be adequate. Adverse changes in economic conditions and circumstances,
however, are more likely to have an adverse impact on these bonds, and therefore
impair timely payment. The likelihood that the ratings of these bonds will fall
below investment grade is higher than for bonds with higher ratings.

BB -- Bonds considered to be speculative. The obligor's ability to pay interest
and repay principal may be affected over time by adverse economic changes.
However, business and financial alternatives can be identified which could
assist the obligor in satisfying its debt service requirements.

B -- Bonds are considered highly speculative. Bonds in this class are lightly
protected as to the obligor's ability to pay interest over the life of the issue
and repay principal when due.

CCC -- Bonds have certain characteristics which, with passing of time, could
lead to the possibility of default on either principal or interest payments.

CC -- Bonds are minimally protected. Default in payment of interest and/or
principal seems probable.

C -- Bonds are in actual or imminent default in payment of interest or
principal.

DDD -- Bonds are in default and in arrears in interest and/or principal
payments. Such bonds are extremely speculative and should be valued only on the
basis of their value in liquidation or reorganization of the obligor.

SHORT TERM RATINGS

Fitch's short-term ratings apply to debt obligations that are payable on demand
or have original maturities of generally up to three years, including commercial
paper, certificates of deposit, medium-term notes, and municipal and investment
notes.



                                      A-5


<PAGE>



The short-term rating places greater emphasis than a long-term rating on the
existence of liquidity necessary to meet the issuer's obligations in a timely
manner.

F-1+ -- Exceptionally Strong Credit Quality. Issues assigned this rating are
regarded as having the strongest degree of assurance for timely payment.

F-1 -- Very Strong Credit Quality. Issues assigned this rating reflect an
assurance of timely payment only slightly less in degree than issues rated
"F-1+".

F-2 -- Good Credit Quality. Issues assigned this rating have a satisfactory
degree of assurance for timely payment, but the margin of safety is not as great
as for issues assigned "F-1+" and "F-1" ratings.

F-3 -- Fair Credit Quality. Issues assigned this rating have characteristics
suggesting that the degree of assurance for timely payment is adequate; however,
near-term adverse changes could cause these securities to be rated below
investment grade.

F-S -- Weak Credit Quality. Issues assigned this rating have characteristics
suggesting a minimal degree of assurance for timely payment and are vulnerable
to near-term adverse changes in financial and economic conditions.

D -- Default. Issues assigned this rating are in actual or imminent payment
default.

LOC -- The symbol LOC indicates that the rating is based on a letter of credit
issued by a commercial bank.

Additional Information

         The fundamental investment limitations set forth above limit a
Portfolio's ability to engage in certain investment practices and purchase
securities to the extent permitted by, or consistent with, the 1940 Act.
Relevant limitations of the 1940 Act are described below, which are based either
on the 1940 Act itself, the rules or regulations thereunder, or interpretations
promulgated by the SEC. As such, these limitations of the 1940 Act are not
"fundamental," that is, the limitations will change as the statute, rules,
regulations or interpretations change, and no shareholder vote will be required
or sought.

         Borrowing, Lending and Issuing Senior Securities.  The 1940 Act
generally limits a Portfolio's ability to borrow to up to one-third of the value
of its total assets.  Borrowing by a Portfolio allows it to leverage its
portfolio, which exposes it to certain risks. Leveraging


                                      -5-


<PAGE>



increases the effect of any increase or decrease in the value of portfolio
securities on a Portfolio's net asset value, and money borrowed will be subject
to interest costs (which may include commitment fees and/or the cost of
maintaining minimum average balances) which may or may not exceed the return
from the securities purchased with borrowed funds.

         The 1940 Act also restricts the ability of any mutual fund to lend.
Under the 1940 Act, a Portfolio may only make loans if expressly permitted to do
so by the Portfolio's investment policies, and a Portfolio may not make loans to
persons who control or are under common control with the Portfolio. Thus, the
1940 Act effectively prohibits a Portfolio from making loans to certain persons
when conflicts of interest or undue influence are most likely present. The
Portfolios may, however, make other loans which if made would expose
shareholders to additional risks, such as the failure of the other party to
repay the loan.

         The ability of a mutual fund to issue senior securities is severely
circumscribed by complex regulatory constraints under the 1940 Act that
restrict, for instance, the amount, timing, and form of senior securities that
may be issued. Certain portfolio management techniques such as the purchase of
securities on margin, short sales, or the writing of puts on portfolio
securities may be considered senior securities unless appropriate steps are
taken to segregate a Portfolio's assets or otherwise cover its obligations.

         Concentration. "Concentration" is interpreted under the 1940 Act to
mean investment of 25% or more of a Portfolio's total assets in a single
industry. If a Portfolio were to "concentrate" its investments in a particular
industry, investors would be exposed to greater risks because the Portfolio's
performance would be largely dependent on that industry's performance.

         Underwriting Securities.  The 1940 Act prohibits a diversified mutual
fund from underwriting securities in excess of 25% of its total assets.

         Commodities and Real Estate. This restriction would permit investment
in commodities, commodities contracts (e.g., futures contracts or options),
forward contracts or real estate to the extent permitted under the 1940 Act.
However, it is unlikely that the Portfolios would make such investments, other
than the use of futures contracts, options, forward contracts and certain real
estate-related securities as explained in the Prospectus and this Statement of
Additional Information. Each Portfolio, however, has the ability to use these
investment techniques in the future. Commodities, as opposed to commodity
futures, represent the actual underlying bulk goods, such as grains, metals and
food stuffs. Real estate-related instruments include real estate investment
trusts, commercial and residential mortgage-backed securities, and real estate
financings, and such instruments are generally sensitive to factors such as
changes in real estate values and property taxes, interest rates, cash flow of
underlying real estate assets, overbuilding, and the management skill and
creditworthiness of the issuer.

                    ADDITIONAL INFORMATION ABOUT SECURITIES,
                     INVESTMENT TECHNIQUES AND RELATED RISKS

RATINGS OF DEBT OBLIGATIONS

         Moody's, S&P and other NRSROs are private organizations that provide
ratings of the credit quality of debt obligations. A description of the ratings
assigned to corporate debt obligations by Moody's and S&P is included as
Appendix A to the Prospectus. A Portfolio may consider these ratings in
determining whether to purchase, sell or hold a security. Ratings are not
absolute assurances of quality. Consequently, securities with the same maturity,
interest rate and rating may have different market prices. Credit rating
agencies attempt to evaluate the safety of principal and interest payments and
do not evaluate the risks of fluctuations in market value. Also, rating agencies
may fail to make timely changes in credit ratings in response to subsequent
events, so that an issuer's current financial condition may be better or worse
than the rating indicates.

MORTGAGE-RELATED SECURITIES

         Mortgage-related securities represent an ownership interest in a pool
of residential mortgage loans. These securities are designed to provide monthly
payments of interest and, in most instances, principal to the investor. The
mortgagor's monthly payments to his/her lending institution are "passed-through"
to investors such as the Portfolios. Most issuers or poolers provide guarantees
of payments, regardless of whether the mortgagor actually makes the payment. The
guarantees made by issuers or poolers are often backed by various forms of
credit, insurance and collateral, although these may be in amounts less than the
full obligation of the pool to its shareholders.

         Pools often consist of whole mortgage loans or participations in loans.
The majority of these loans are made to purchasers of one- to four-family homes.
The terms and characteristics of the mortgage instruments are generally uniform
within a pool but may vary among pools. For example, in addition to fixed-rate,
fixed-term mortgages, the Portfolios may purchase pools of variable-rate
mortgages, growing-equity mortgages, graduated-payment mortgages and other
types.

         All poolers apply standards for qualification to lending institutions
which originate mortgages for the pools. Poolers also establish credit standards
and underwriting criteria for individual mortgages included in the pools. In
addition, many mortgages included in pools are insured through private mortgage
insurance companies.

         The average life of mortgage-related securities varies with the
maturities and the nature of the underlying mortgage instruments. For example,
securities issued by the Government National Mortgage Association ("GNMA") tend
to have a longer average life than participation certificates ("PCs") issued by
the Federal Home Loan Mortgage Corporation ("FHLMC")


                                      -7-


<PAGE>



because there is a tendency for the conventional and privately-insured mortgages
underlying FHLMC PCs to repay at faster rates than the Federal Housing
Administration and Veterans Administration loans underlying GNMAs. In addition,
the term of a security may be shortened by unscheduled or early payments of
principal and interest on the underlying mortgages. The occurrence of mortgage
prepayments is affected by factors including the level of interest rates,
general economic conditions, the location and age of the mortgage and other
social and demographic conditions.

         In determining the dollar-weighted average maturity of a Portfolio, the
Portfolio's Adviser will follow industry practice in assigning an average life
to the mortgage-related securities held by each Portfolio unless the interest
rate on the mortgages underlying the securities is such that a different
prepayment rate is likely. For example, if a GNMA has a high interest rate
relative to the market, that GNMA is likely to have a shorter overall maturity
than a GNMA with a market rate coupon. Moreover, Western Asset may deem it
appropriate to change the projected average life for a Portfolio's
mortgage-related securities as a result of fluctuations in market interest rates
and other factors.

         Yields on mortgage-related securities are typically quoted based on the
maturity of the underlying instruments and the associated average life
assumption. Actual prepayment experience may cause the yield to differ from the
yield expected on the basis of average life. Reinvestment of the prepayments may
occur at higher or lower interest rates than the original investment, thus
affecting the yield of the Portfolio. The compounding effect from reinvestments
of monthly payments received by each Portfolio will increase the yield to
shareholders compared to bonds that pay interest semi-annually.

PRIVATE MORTGAGE-RELATED SECURITIES

         Certain private mortgage pools are organized in such a way that the SEC
staff considers them to be closed-end investment companies. Each Portfolio's
investment in such pools is constrained by federal statute, which restricts
investments in the shares of other investment companies.

         The private mortgage-related securities in which the Portfolios may
invest include foreign mortgage pass-through securities ("Foreign
Pass-Throughs"), which are structurally similar to the pass-through instruments
described above. Such securities are issued by originators of and investors in
mortgage loans, including savings and loan associations, mortgage bankers,
commercial banks, investment bankers, specialized financial institutions and
special purpose subsidiaries of the foregoing. Foreign Pass-Throughs usually are
backed by a pool of fixed rate or adjustable-rate mortgage loans. Certain
Foreign Pass-Throughs in which the Portfolios invest typically are not
guaranteed by an entity having the credit status of GNMA, but generally utilize
various types of credit enhancement.


                                      -8-


<PAGE>




ASSET-BACKED SECURITIES

         Asset-backed securities are structurally similar to mortgage-backed
securities, but are secured by interests in a different type of receivable.
Asset-backed securities therefore present certain risks that are not presented
by mortgage-related debt securities or other securities in which the Portfolios
may invest. Primarily, these securities do not have the benefit of the same
security interest in the related collateral. Credit card receivables are
generally unsecured and the debtors are entitled to the protection of a number
of state and federal consumer credit laws, many of which give such debtors the
right to set off certain amounts owed on the credit cards, thereby reducing the
balance due. Most issuers of automobile receivables permit the servicers to
retain possession of the underlying obligations. If the servicer were to sell
these obligations to another party, there is a risk that the purchaser would
acquire an interest superior to that of the holders of the related automobile
receivables. In addition, because of the large number of vehicles involved in a
typical issuance and technical requirements under state laws, the trustee for
the holders of the automobile receivables may not have a proper security
interest in all of the obligations backing such receivables. Therefore, there is
the possibility that recoveries on repossessed collateral may not, in some
cases, be available to support payments on these securities. Because
asset-backed securities are relatively new, the market experience in these
securities is limited and the market's ability to sustain liquidity through all
phases of the market cycle is not certain.

NON-GOVERNMENTAL FIXED INCOME AND OTHER DEBT SECURITIES

         A Portfolio's investments in fixed income and other debt securities of
non-governmental domestic or foreign issuers are limited to fixed income or
other debt obligations (bonds, debentures, notes and other similar instruments)
which meet the minimum ratings criteria set forth for the Portfolio or, if
unrated, are determined by the Portfolio's Adviser to be of comparable quality
to fixed income or other debt obligations in which the Portfolio may invest.

         Where one of the NRSROs has assigned an investment grade rating to an
instrument and others have given it a lower rating, the Portfolios may consider
the instrument to be investment grade. The market for lower-rated securities may
be thinner and less active than that for higher-rated securities, which can
adversely affect the prices at which these securities can be sold, and may make
it difficult for a Portfolio to obtain market quotations daily. If market
quotations are not available, these securities will be valued by a method that
the Portfolios' Boards of Directors believe accurately reflects fair market
value. Judgment may play a greater role in valuing lower-rated debt securities
than is the case with respect to securities for which a broader range of dealer
quotations and last-sale information is available.

         Although the prices of lower-rated bonds are generally less sensitive
to interest rate changes than are higher-rated bonds, the prices of lower-rated
bonds may be more sensitive to adverse economic changes and developments
regarding the individual issuer. Although the market for lower-rated debt
securities is not new, and the market has previously weathered


                                      -9-


<PAGE>



economic downturns, there has been in recent years a substantial increase in the
use of such securities to fund corporate acquisitions and restructurings.
Accordingly, the past performance of the market for such securities may not be
an accurate indication of its performance during future economic downturns or
periods of rising interest rates. When economic conditions appear to be
deteriorating, medium- to lower-rated securities may decline in value due to
heightened concern over credit quality, regardless of the prevailing interest
rates. Investors should carefully consider the relative risks of investing in
high yield securities and understand that such securities are not generally
meant for short-term investing.

         Adverse economic developments can disrupt the market for lower-rated
securities, and severely affect the ability of issuers, especially highly
leveraged issuers, to service their debt obligations or to repay their
obligations upon maturity which may lead to a higher incidence of default on
such securities. In addition, the secondary market for lower-rated securities,
which is concentrated in relatively few market makers, may not be as liquid as
the secondary market for more highly rated securities. As a result, a Portfolio
could find it more difficult to sell these securities or may be able to sell the
securities only at prices lower than if such securities were widely traded.
Therefore, prices realized upon the sale of such lower rated or unrated
securities, under these circumstances, may be less than the prices used in
calculating a Portfolio's net asset value.

         Lower-rated or unrated debt obligations also present risks based on
payment expectations. If an issuer calls an obligation for redemption, the
Portfolio may have to replace the security with a lower yielding security,
resulting in a decreased return for investors. If a Portfolio experiences
unexpected net redemptions, it may be forced to sell its higher-rated
securities, resulting in a decline in the overall credit quality of the
Portfolio's investment portfolio and increasing the exposure of the Portfolio to
the risks of lower-rated securities.

RESTRICTED SECURITIES

         Restricted securities may be sold only (1) pursuant to SEC Rule 144A or
other exemption, (2) in privately negotiated transactions or (3) in public
offerings with respect to which a registration statement is in effect under the
Securities Act of 1933, as amended. Rule 144A securities, although not
registered in the U.S., may be sold to qualified institutional buyers in
accordance with Rule 144A under the Securities Act of 1933, as amended. Each
Portfolio's Adviser, acting pursuant to guidelines established by its Board of
Directors, may determine that some Rule 144A securities are liquid for purposes
of limitations on the amount of illiquid investments a Portfolio may own. Where
registration is required, a Portfolio may be obligated to pay all or part of the
registration expenses and a considerable period may elapse between the time of
the decision to sell and the time the Portfolio may be permitted to sell a
security under an effective registration statement. If, during such a period,
adverse market conditions were to develop, the Portfolio might obtain a less
favorable price than prevailed when it decided to sell.

BORROWINGS

         The 1940 Act requires a Portfolio to maintain continuous asset coverage
(that is, total assets including borrowings, less liabilities exclusive of
borrowings) of at least 300% of the amount borrowed. If the asset coverage
should decline below 300% as a result of market fluctuations or for other
reasons, a Portfolio may be required to sell some of its holdings within three
days to reduce the debt and restore the 300% asset coverage, even though it may
be disadvantageous from an investment standpoint to sell securities at that
time. Borrowing may increase the effect on net asset value of any increase or
decrease in the market value of the Portfolio.

         Money borrowed will be subject to interest costs which may or may not
be recovered by appreciation of the securities purchased. A Portfolio also may
be required to maintain minimum average balances in connection with such
borrowing or to pay a commitment or other fee to maintain a line of credit;
either of these requirements would increase the cost of borrowing over the
stated interest rate. The Portfolios may enter into reverse repurchase
agreements and dollar roll transactions as a method of borrowing.

OPTIONS ON SECURITIES

         A Portfolio may purchase call options on securities for any purpose.
For example, a call option may be purchased by a Portfolio on a security that
its Adviser intends to include in the Portfolio's investment portfolio in order
to fix the cost of a future purchase. Call options also may be used as a means
of participating in an anticipated price increase of a security on a more
limited risk basis than would be possible if the security itself were purchased.
In the event of a decline in the price of the underlying security, use of this
strategy would serve to limit the Portfolio's potential loss to the option
premium paid; conversely, if the market price of the underlying security
increases above the exercise price and the Portfolio either sells or exercises
the option, any profit realized would be reduced by the premium.

         A Portfolio may purchase put options on securities for any purpose. For
example, a put option may be purchased by a Portfolio in order to hedge against
a decline in the market value of securities held in its portfolio. The put
option enables a Portfolio to sell the underlying security at the predetermined
exercise price; thus the potential for loss to the Portfolio below the exercise
price is limited to the option premium paid. If the market price of the
underlying security is higher than the exercise price of the put option, any
profit the Portfolio realizes on the sale of the security would be reduced by
the premium paid for the put option less any amount for which the put option may
be sold.

         A Portfolio may also write call and put options.

FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS

         Each Portfolio will limit its use of futures contracts and futures
options to hedging transactions or other circumstances permitted to registered
investment companies by regulatory authorities. For example, a Portfolio might
use futures contracts to attempt to hedge against anticipated changes in
interest rates that might adversely affect either the value of the Portfolio's
securities or the price of the securities which the Portfolio intends to
purchase. A Portfolio's hedging may include sales of futures contracts as an
offset against the effect of expected increases in interest rates, and purchases
of futures contracts as an offset against the effect of expected declines in
interest rates. Although other techniques could be used to reduce exposure to
interest rate fluctuations, a Portfolio may be able to hedge its exposure more
effectively and perhaps at a lower cost by using futures contracts and options
on futures contracts.

         A futures contract on a security or foreign currency is a bilateral
agreement pursuant to which one party agrees to make, and the other party agrees
to accept, delivery of the specified type of security or foreign currency called
for in the contract at a specified future time and at a specified price. A
Portfolio may, for example, purchase a futures contract on a security or foreign
currency when it intends to purchase securities or foreign currency but has not
yet done so. This strategy may minimize the effect of all or part of an increase
in the market price of the security or the relative value of the foreign
currency that a Portfolio intends to purchase in the future. A rise in the price
of the security or foreign currency prior to its purchase may either be offset
by an increase in the value of the futures contract purchased by a Portfolio or
avoided by taking delivery of the security or foreign currency under the futures
contract. Conversely, a fall in the market price of the underlying security or
foreign currency may result in a corresponding decrease in the value of the
futures position. A Portfolio may sell a futures contract on a security or
foreign currency, for example, in order to continue to receive the income from a
security or foreign currency, while endeavoring to avoid part or all of the
decline in the market value of that security that would accompany an increase in
interest rates.

         A Portfolio may also purchase a call option on a futures contract to
hedge against a market advance in securities or foreign currency which the
Portfolio plans to acquire at a future date. The purchase of a call option on a
futures contract is analogous to the purchase of a call option on an individual
security or foreign currency which can be used as a temporary substitute for a
position in the security itself. A Portfolio also may write covered call options
on futures contracts as a partial hedge against a decline in the price of
securities or foreign currency held in the Portfolio's investment portfolio, or
purchase put options on futures contracts in order to hedge against a decline in
the value of securities or foreign currency held in the Portfolio's investment
portfolio. A Portfolio may write a covered put option as a partial anticipatory
hedge.

         When a purchase or sale of a futures contract is made by a Portfolio,
the Portfolio is required to deposit with its custodian (or a broker, if legally
permitted) a specified amount of cash or U.S. Government securities ("initial
margin"). The margin required for a futures contract is set by the exchange on
which the contract is traded and may be modified during the term of the


                                      -12-


<PAGE>



contract. The initial margin is in the nature of a performance bond or good
faith deposit on the futures contract which is returned to the Portfolio upon
termination of the contract, assuming all contractual obligations have been
satisfied. Under certain circumstances, such as during periods of high
volatility, a Portfolio may be required by an exchange to increase the level of
its initial margin payment. Additionally, initial margin requirements may be
increased generally in the future by regulatory action. Each Portfolio expects
to earn interest income on its initial margin deposits. A futures contract held
by a Portfolio is valued daily at the official settlement price of the exchange
on which it is traded. Each day the Portfolio pays or receives cash, called
"variation margin," equal to the daily change in value of the futures contract.
This process is known as "marking to market." Variation margin does not
represent a borrowing or loan by a Portfolio but is instead settlement between
the Portfolio and the broker of the amount one would owe the other if the
futures contract expired. In computing daily net asset value, each Portfolio
will mark to market its open futures positions.

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

         Although some futures contracts call for making or taking delivery of
the underlying securities or currencies, generally those contracts are closed
out prior to delivery by offsetting purchases or sales of matching futures
contracts (involving the same currency or underlying security and delivery
month). If an offsetting purchase price is less than the original sale price,
the Portfolio realizes a gain, or if it is more, the Portfolio realizes a loss.
If an offsetting sale price is more than the original purchase price, the
Portfolio realizes a gain, or if it is less, the Portfolio realizes a loss. The
Portfolio will also bear transaction costs for each contract which will be
included in these calculations.

         A Portfolio will not enter into futures contracts or option positions
if, immediately thereafter, the initial margin deposits plus premiums paid by
it, less the amount by which any such options positions are "in-the-money" at
the time of purchase, would exceed 5% of the fair market value of the
Portfolio's total assets. A call option is "in-the-money" if the value of the
futures contract that is the subject of the option exceeds the exercise price. A
put option is "in-the-money" if the exercise price exceeds the value of the
futures contract that is the subject of the option.

         The requirements for qualification as a regulated investment company
also may limit the extent to which a Portfolio may enter into futures or options
on futures.  See "Additional Tax Information."

RISKS ASSOCIATED WITH FUTURES AND OPTIONS

         In considering the Portfolios' use of futures contracts and options,
particular note should

                                      -13-


<PAGE>



be taken of the following:

         (1) Positions in futures contracts and options may be closed out only
on an exchange or board of trade which provides a secondary market for such
futures contracts or options. Futures exchanges may limit the amount of
fluctuation permitted in certain futures contract and option prices during a
single trading day. The daily limit establishes the maximum amount that the
price of a futures contract or option may vary either up or down from the
previous day's settlement price at the end of the current trading session. Once
the daily limit has been reached in a futures contract or option subject to the
limit, no more trades may be made on that day at a price beyond that limit. The
daily limit governs only price movements during a particular trading day and
therefore does not limit potential losses because the limit may work to prevent
the liquidation of unfavorable positions. For example, futures prices have
occasionally moved to the daily limit for several consecutive trading days with
little or no trading, thereby preventing prompt liquidation of positions and
subjecting some holders of futures contracts to substantial losses.

         (2) The ability to establish and close out positions in either futures
contracts or exchange-listed options is also subject to the maintenance of a
liquid secondary market. Consequently, it may not be possible for a Portfolio to
close a position and, in the event of adverse price movements, the Portfolio
would have to make daily cash payments of variation margin (except in the case
of purchased options). However, in the event futures contracts or options have
been used to hedge portfolio securities, such securities generally will not be
sold until the contracts can be terminated. In such circumstances, an increase
in the price of the securities, if any, may partially or completely offset
losses on the futures contract. However, there is no guarantee that the price of
the securities will, in fact, correlate with the price movements in the
contracts and thus provide an offset to losses on the contracts. The inability
to close out a futures or option position may also restrict the Portfolio's
ability to sell the underlying security or currency at a time when the Adviser
might otherwise do so.

         (3) Successful use by a Portfolio of futures contracts and options will
depend upon its Adviser's ability to predict market movements, which may require
different skills and techniques than predicting changes in the prices of
individual securities. Moreover, futures contracts relate not to the current
level of the underlying instrument but to anticipated levels at some point in
the future. There is, in addition, the risk that movements in the price of the
futures contract or option will not correlate with movements in the prices of
the securities or currencies being hedged. If the price of the securities or
currencies being hedged has moved in a favorable direction, this advantage may
be partially offset by losses in the futures or option position. In addition, if
the Portfolio has insufficient cash, it may have to sell assets from its
investment portfolio to meet daily variation margin requirements. Any such sale
of assets may or may not be made at prices that reflect the rising market;
consequently, a Portfolio may need to sell assets at a time when such sales are
disadvantageous to the Portfolio. If the price of the futures or option contract
moves more than the price of the underlying securities or currencies, the
Portfolio will experience either a loss or a gain on the futures contract or
option that may or may not be


                                      -14-


<PAGE>



completely offset by movements in the price of the securities or currencies that
are the subject of the hedge.

         (4) The value of an option position will reflect, among other things,
the current market price of the underlying security, currency or futures
contract, the time remaining until expiration, the relationship of the exercise
price to the market price, the historical price volatility of the underlying
security, currency or futures contract and general market conditions. For this
reason, the successful use of options as a hedging strategy depends upon the
Adviser's ability to forecast the direction of price fluctuations in the
underlying market.

         (5) In addition to the possibility that there may be an imperfect
correlation, or no correlation at all, between price movements in the futures
and options position and the securities or currencies being hedged, movements in
the prices of futures and options contracts may not correlate perfectly with
movements in the prices of the hedged securities or currencies due to price
distortions in the futures and options markets. There may be several reasons
unrelated to the value of the underlying securities or currencies which cause
this situation to occur. First, as noted above, all participants in the futures
market are subject to initial and variation margin requirements. If, to avoid
meeting additional margin deposit requirements or for other reasons, investors
choose to close a significant number of futures contracts through offsetting
transactions, distortions in the normal price relationship between the
securities or currencies and the futures markets may occur. Second, because the
margin deposit requirements in the futures market are less onerous than margin
requirements in the securities market, there may be increased participation by
speculators in the futures market; such speculative activity in the futures
market also may cause temporary price distortions. Third, participants could
make or take delivery of the underlying securities or currencies instead of
closing out their contracts. As a result, a correct forecast of general market
trends may not result in successful hedging through the use of futures or
options contracts over the short term. In addition, activities of large traders
involving arbitrage and other investment strategies may result in temporary
price distortions.

         (6) Options normally have expiration dates of up to nine months. The
exercise price of the options may be below, equal to or above the current market
value of the underlying security, currency or futures contract. Options that
expire unexercised have no value, and the Portfolio will realize a loss in the
amount paid and any transaction costs.

         (7) Like options on securities, options on futures contracts have a
limited life. The ability to establish and close out options on futures will be
subject to the development and maintenance of liquid secondary markets on the
relevant exchanges or boards of trade. There can be no certainty that liquid
secondary markets for all options on futures contracts will develop.

         (8) Purchasers of options on futures contracts pay a premium in cash at
the time of purchase. This amount and the transaction costs are all that is at
risk. Sellers of options on futures contracts, however, must post an initial
margin and are subject to additional margin calls which could be substantial in
the event of adverse price movements. In addition, although the


                                      -15-


<PAGE>



maximum amount at risk when the Portfolio purchases an option is the premium
paid for the option and the transaction costs, there may be circumstances when
the purchase of an option on a futures contract would result in a loss to the
Portfolio when the use of a futures contract would not, such as when there is no
movement in the value of the securities or currencies being hedged.

         (9) A Portfolio's activities in the futures and options markets may
result in a higher portfolio turnover rate and additional transaction costs in
the form of added brokerage commissions; however, a Portfolio also may save on
commissions by using such contracts as a hedge rather than buying or selling
individual securities in anticipation or as a result of market movements.

         (10) A Portfolio may purchase and write both exchange-traded options
and options traded on the OTC market. Exchange markets for options on debt
securities exist but are relatively new, and the ability to establish and close
out positions on the exchanges is subject to the maintenance of a liquid
secondary market. Although the Portfolios intend to purchase or write only those
exchange-traded options for which there appears to be an active secondary
market, there is no assurance that a liquid secondary market will exist for any
particular option at any specific time. Closing transactions may be effected
with respect to options traded in the OTC markets only by negotiating directly
with the other party to the option contract, or in a secondary market for the
option if such market exists. Although the Portfolios will enter into OTC
options only with dealers which agree to enter into, and which are expected to
be capable of entering into, closing transactions with the Portfolios, there can
be no assurance that a Portfolio will be able to liquidate an OTC option at a
favorable price at any time prior to expiration. In the event of insolvency of
the contra-party, a Portfolio may be unable to liquidate an OTC option.
Accordingly, it may not be possible to effect closing transactions with respect
to certain options, with the result that the Portfolio would have to exercise
those options which it has purchased in order to realize any profit. With
respect to options written by a Portfolio, the inability to enter into a closing
transaction may result in material losses to the Portfolio. For example, because
a Portfolio must maintain a covered position with respect to any call option it
writes on a security or futures contract the Portfolio may not sell the
underlying security or futures contract or invest any cash, U.S. Government
securities or short-term debt securities used as cover during the period it is
obligated under such option. This requirement may impair a Portfolio's ability
to sell a portfolio security or make an investment at a time when such a sale or
investment might be advantageous.

ADDITIONAL RISKS OF OPTIONS ON SECURITIES, FUTURES CONTRACTS AND OPTIONS ON
FUTURES CONTRACTS TRADED ON FOREIGN EXCHANGES

         Options on securities, options on currencies, futures contracts and
options on futures contracts may be traded on foreign exchanges. Such
transactions may not be regulated as effectively as similar transactions in the
United States, may not involve a clearing mechanism and related guarantees and
are subject to the risk of governmental actions affecting trading in, or the
price of, foreign securities. The value of such positions also could be
adversely affected by

                                      -16-


<PAGE>



(1) other complex foreign political, legal and economic factors, (2) lesser
availability than in the United States of data on which to make trading
decisions, (3) delays in the Portfolios' ability to act upon economic events
occurring in foreign markets during non-business hours in the United States, (4)
the imposition of different exercise and settlement terms and procedures and
margin requirements than in the United States and (5) lesser trading volume.

COVER FOR HEDGING STRATEGIES

         Each Portfolio will comply with guidelines established by the SEC with
respect to coverage of hedging strategies by mutual funds, and, if the
guidelines so require, will set aside cash or liquid securities in a segregated
account with its custodian in the amount prescribed, as marked to market daily.
Securities, options or futures positions used for cover and securities held in a
segregated account cannot be sold or closed out while the hedging strategy is
outstanding, unless they are replaced with similar assets. As a result, there is
a possibility that the use of cover or segregation involving a large percentage
of a Portfolio's assets could impede portfolio management or a Portfolio's
ability to meet redemption requests or other current obligations.

DURATION

         Traditionally, a fixed income security's term to maturity was used to
evaluate the sensitivity of the security's price to changes in interest rates.
Duration is a measure of the expected life of a fixed income security on a cash
flow basis, that was developed as a more precise method of evaluating such
sensitivity. A security's term to maturity measures only the time until final
payment of the security, and does not take into account the pattern of payments
made prior to maturity. Duration takes time intervals over which the interest
and principal payments are scheduled and weights each by the present values of
the cash to be received at the corresponding future point in time.

         There may be circumstances under which even duration calculations do
not properly reflect the interest rate exposure of a security. For example,
floating variable rate securities may have final maturities of ten or more
years; however, their interest exposure corresponds to the frequency of the
coupon reset. Similarly, many mortgage pass-through securities may have stated
final maturities of 30 years, but current prepayment rates are more critical in

determining the security's interest rate exposure. In these situations, the
Adviser may consider other analytical techniques that incorporate the economic
life of a security into its determination of interest rate exposure.

                          VALUATION OF PORTFOLIO SHARES

         As described in the Prospectus, securities owned by any of the
Portfolios (other than the Money Market Portfolios) for which market quotations
are readily available are valued at current market value. Securities are valued
at the last sale price for a comparable position on the day the

                                      -17-


<PAGE>


securities are being valued or, lacking any sales on such day, at the last
available bid price. In cases where securities are traded on more than one
market, the securities are generally valued on the market considered by the
Adviser as the primary market.

         Occasionally, events affecting the value of foreign investments occur
between the time at which they are determined and the close of trading on the
Exchange, which events will not be reflected in a computation of a Portfolio's
net asset value on that day. If events materially affecting the value of such
investments occur during such time period, the investments will be valued at
their fair value as determined in good faith by, or under the direction of, the
Board of Directors.

USE OF THE AMORTIZED COST METHOD BY THE MONEY MARKET PORTFOLIOS

         The Board of Directors of the Money Market Portfolios has decided that
the best method for determining the value of securities held by the Money Market
Portfolios is amortized cost. Under this method, portfolio instruments are
valued at acquisition cost as adjusted for amortization of premium or accrual of
discount rather than at current market value. The Board of Directors continually
assesses this method of valuation and recommends changes where necessary to
assure that the Money Market Portfolios' investments are valued at their fair
value as determined in good faith by, or under the direction of, the Directors.

         The Money Market Portfolios' use of the amortized cost method of
valuing portfolio instruments held by it depends on its compliance with Rule
2a-7 under the 1940 Act. Under that Rule, the Board of Directors must establish
procedures reasonably designed to stabilize the net asset value per share at
$1.00 per share, taking into account current market conditions and the
Portfolio's investment objective.

MONITORING PROCEDURES

         The Board of Directors' procedures include monitoring the relationship
between the amortized cost value per share and a net asset value per share based
upon available indications of market value. The Board will take any steps it
considers appropriate if there is a difference of more than 0.5% between the two
(such as redeeming in kind or shortening the average portfolio maturity) to
minimize any material dilution or other unfair results arising from differences
between the two methods of determining net asset value.

INVESTMENT RESTRICTIONS

         Rule 2a-7 requires each Money Market Portfolio to limit its investments
to instruments that present minimal credit risk, in the opinion of the Board,
and are of high quality. The Rule also requires each Money Market Portfolio to
maintain a dollar-weighted average portfolio maturity of not more than 90 days
that is appropriate to the objective of maintaining a stable net asset value of
$1.00 per share. In addition, no instrument considered under SEC rules to have a


                                      -18-


<PAGE>



remaining maturity of more than 397 days can be purchased by the Money Market
Portfolios. The Money Market Portfolios may hold securities with maturities
greater than 397 days as collateral for repurchase agreements and other
collateralized transactions of short duration. Should the disposition of a
portfolio security result in a dollar-weighted average portfolio maturity of
more than 90 days, the relevant Money Market Portfolio will invest its available
cash to reduce the average maturity to 90 days or less as soon as possible.

         In periods of declining interest rates, the indicated daily yield on
shares of each Money Market Portfolio computed by dividing the annualized daily
income on the portfolio by the net asset value computed as above may tend to be
higher than a similar computation made by using a method of valuation based upon
market prices and estimates. In periods of rising interest rates, the indicated
daily yield on shares of each Money Market Portfolio computed the same way may
tend to be lower than a similar computation made by using a method of
calculation based upon market prices and estimates.

MANAGER AND ADVISERS

         THE MANAGER. The Manager serves as investment manager to the Fund under
the Investment Management Agreement dated May 29, 1998 between the Manager and
the Fund (the "Management Agreement"). The Management Agreement was most
recently approved by the Board of Directors, including a majority of Independent
Directors, on March 6, 1998.

         Under the Management Agreement, the Manager is responsible, subject to
the general supervision of the Fund's Board of Directors, for the actual
management of the Fund's assets, including the responsibility for making
decisions and placing orders to buy, sell or hold a particular security,
consistent with the investment objectives and policies described in the
Prospectus and this Statement of Additional Information. The Manager also is
responsible for the compensation of Directors and officers of the Fund who are
employees of the Manager or its affiliates. The Manager receives for its
services a fee as described in the Prospectus. As noted below, the Manager has
delegated responsibility for the selection of the Fund's investments to the
Advisers.

         Each Portfolio pays all of its other expenses which are not assumed by
the Manager. These expenses include, among others, expenses of preparing and
printing prospectuses, statements of additional information, proxy statements
and reports and of distributing them to existing shareholders, custodian
charges, transfer agency fees, organizational expenses, compensation of the
Directors who are not "interested persons" of the Manager, or its affiliates, as
that term is defined in the 1940 Act, legal and audit expenses, insurance
expenses, expenses of registering and qualifying shares of the Portfolios for
sale under federal and state law, Rule 12b-1 fees, governmental fees, expenses
incurred in connection with membership in investment company organizations,
interest expense, taxes and brokerage fees and commissions. The Portfolios also
are liable for such nonrecurring expenses as may arise, including litigation to
which a Portfolio or the Fund may be a party. The Fund may also have an
obligation to indemnify its Directors and officers with respect to litigation.

         Under the Management Agreement, the Manager will not be liable for any
error of judgment or mistake of law or for any loss suffered by the Portfolios
in connection with the performance of the Management Agreement, except a loss
resulting from a breach of fiduciary duty with respect to the receipt of
compensation for services or a loss resulting from willful misfeasance, bad
faith or gross negligence on its part in the performance of its duties or from
reckless disregard by it of its obligations or duties thereunder.


                                      -24-

         The Management Agreement terminates automatically upon assignment and
is terminable with respect to any Portfolio at any time without penalty by vote
of the Fund's Board of Directors, by vote of a majority of that Portfolio's
outstanding voting securities, or by the Manager, on not less than 60 days'
notice to the Fund, and may be terminated immediately upon the mutual written
consent of the Manager and the Fund.

<PAGE>



terminable at any time without penalty by vote of the Fund's Board of Directors,
by vote of a majority of the Portfolio's outstanding voting securities, or by
WAGM, on not less than 60 days' notice, and may be terminated immediately upon
the mutual written consent of the parties.

         DISTRIBUTORS

         Legg Mason acts as a distributor of the shares of LM Institutional Fund
Advisors I, Inc. pursuant to an Underwriting Agreement with the Fund dated
August 24, 1990 and amended May 29, 1998 (the "Underwriting Agreement").

         Legg Mason is not obligated to sell any specific amount of Fund shares
and receives no compensation pursuant to the Underwriting Agreement. The
Underwriting Agreement is terminable with respect to any Portfolio without
penalty, at any time, by vote of a majority of the Fund's Independent Directors,
or by vote of the holders of a majority of the shares of that Portfolio, or by
Legg Mason upon 60 days' notice to the Fund.

         The Fund has adopted a Plan which, among other things, permits the Fund
to pay Legg Mason fees for its services related to sales and distribution of
Financial Intermediary Class shares and the provision of ongoing services to
Financial Intermediary Class shareholders. Payments are made only from assets
attributable to Financial Intermediary Class shares. Under the Plan, the
aggregate fees may not exceed an annual rate of 0.40% (currently limited to
0.25%) of each Portfolio's average daily net assets attributable to Financial
Intermediary Class shares. Fees for the Western Asset Money Market Portfolio and
the Western Asset Government Money Market Portfolio are additionally currently
limited to the annual rate of 0.10% of average daily net assets attributable to
Financial Intermediary Class shares. Distribution activities for which such
payments may be made include, but are not limited to, compensation to persons
who engage in or support distribution and redemption of Shares, printing of
prospectuses and reports for persons other than existing shareholders,
advertising, preparation and distribution of sales literature, overhead, travel
and telephone expenses, all with respect to Financial Intermediary Class shares
only.

         The Plan was approved by Legg Mason Fund Adviser, Inc., as sole
shareholder of the Financial Intermediary Class of each Portfolio on May 29,
1998. Legg Mason may pay all or a portion of the fee to its investment
executives.

         The Plan will continue in effect only so long as it is approved at
least annually by the vote of a majority of the Board of Directors, including a
majority of the 12b-1 Directors, cast in person at a meeting called for the
purpose of voting on the Plan. The Plan may be terminated by a vote of a
majority of the 12b-1 Directors or by a vote of a majority of the outstanding
voting securities of the Financial Intermediary Class shares. Any change in the
Plan that would materially increase the distribution cost to a Portfolio
requires shareholder approval; otherwise the Plan may be amended by the
Directors, including a majority of the 12b-1 Directors, as previously described.


                                      -27-


<PAGE>




         In accordance with Rule 12b-1, the Plan provides that Legg Mason will
submit to the Fund's Board of Directors, and the Directors will review, at least
quarterly, a written report of any amounts expended pursuant to the Plan and the
purposes for which expenditures were made. In addition, as long as the Plan is
in effect, the selection and nomination of the Independent Directors will be
committed to the discretion of such Independent Directors.

         Arroyo Seco, Inc. ("Arroyo Seco"), 117 East Colorado Boulevard,
Pasadena, CA 91105, a wholly owned subsidiary of Western Asset, is also
authorized to offer the shares of LM Institutional fund Advisors I, Inc. for
sale to its customers pursuant to an Agreement dated November 9, 1995. This
Agreement was most recently approved by the Board of Directors of LM
Institutional Fund Advisors I, Inc., including a majority of the Independent
Directors, on March 6, 1998.

         LM Institutional Fund Advisors I, Inc. makes no payments to Arroyo Seco
in connection with the offer or sale of the Fund's shares, and Arroyo Seco does
not collect any commissions or other fees from customers in connection with the
offer or sale of the Fund's shares. Arroyo Seco is not obligated to sell any
specific amount of Fund shares. The Agreement is terminable without penalty, at
any time, by vote of a majority of the Fund's Directors, a majority of the
Fund's Independent Directors, or a majority of the Fund's outstanding shares, or
by Arroyo Seco upon 60 days' notice to the Fund.

                            PURCHASES AND REDEMPTIONS

         The Fund reserves the right to modify or terminate the mail, telephone
or wire redemption services described in the Prospectus at any time. The Fund
also reserves the right to suspend or postpone redemptions (1) for any period
during which the Exchange is closed (other than for customary weekend and
holiday closings), (2) when trading in markets the Fund normally utilizes is
restricted or an emergency, as defined by rules and regulations of the SEC,
exists, making disposal of the Fund's investments or determination of its net
asset value not reasonably practicable, or (3) for such other periods as the SEC
by regulation or order may permit for the protection of the Fund's shareholders.
In the case of any such suspension, an investor may either withdraw the request
for redemption or receive payment based upon the net asset value next determined
after the suspension is lifted.

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

<PAGE>


                               EXCHANGE PRIVILEGE

         Shareholders in any of the Portfolios are entitled to exchange their
shares for shares of the other Portfolios or of any portfolio of LM
Institutional Fund Advisors II, Inc., provided that such shares are eligible for
sale in the shareholder's state of residence, and are being offered at the time.

         When a shareholder decides to exchange shares of a Portfolio, the
Fund's transfer agent will redeem shares of the Portfolio and invest the
proceeds in shares of the Portfolio selected. Redemptions of shares of the
Portfolio will be made at their net asset value determined on the same day that
the request is received in proper order, if received before the close of
business of the Exchange. If the request is received by the transfer agent after
the close of business on the Exchange, shares will be redeemed at their net
asset value determined as of the close of the Exchange on the next day the
Exchange is open.

         There is no charge for the exchange privilege and no sales charge
imposed on an exchange, but the Portfolios reserve the right to modify or
terminate the exchange privilege at any time.  For more information concerning
the exchange privilege, or to make an exchange, please contact the Portfolios.

                      PORTFOLIO TRANSACTIONS AND BROKERAGE

         Under the Advisory Agreements and Sub-Advisory Agreements, the Advisers
are responsible for the execution of the Portfolios' transactions. In selecting
brokers or dealers, the Advisers must seek the most favorable price (including
the applicable dealer spread) and execution for such transactions, subject to
the possible payment as described below of higher brokerage commissions or
spreads to brokers or dealers who provide research and analysis. The Portfolios
may not always pay the lowest commission or spread available. Rather, in placing
orders on behalf of the Portfolios, the Advisers will also take into account
such factors as size of the order, difficulty of execution, efficiency of the
executing broker's or dealer's facilities (including the services described
below) and any risk assumed by the executing broker or dealer.

         Consistent with the policy of obtaining most favorable price and
execution, an Adviser may give consideration to research, statistical and other
services furnished by brokers or dealers to the Adviser for its use, may place
orders with brokers or dealers who provide supplemental investment and market
research and securities and economic analysis, and may pay to those brokers or
dealers a higher brokerage commission or spread than may be charged by other
brokers or dealers. Such research, analysis and other services may be useful to
an Adviser in connection with services to clients other than the Portfolios. An
Adviser's fee is not reduced by reason of its receiving such brokerage and
research services.

         The Portfolios may not buy securities from, or sell securities to, an
Adviser or its affiliated persons as principal, except as permitted by the rules
and regulations of the SEC.


                                      -29-


<PAGE>



Subject to certain conditions, the Portfolios may purchase securities that are
offered in underwritings in which an affiliate of an Adviser is a participant,
although the Portfolios may not make such purchases directly from such
affiliate.

         The Advisers will select brokers to execute portfolio transactions. In
the over-the-counter market, the Portfolios generally will deal with responsible
primary market-makers unless a more favorable execution can otherwise be
obtained.

         Investment decisions for the Portfolios are made independently from
those of other funds and accounts advised by the Advisers. However, the same
security may be held in the portfolios of more than one fund or account. When
two or more accounts simultaneously engage in the purchase or sale of the same
security, the prices and amounts will be equitably allocated to each account. In
some cases, this procedure may adversely affect the price or quantity of the
security available to a particular account. In other cases, however, an
account's ability to participate in larger volume transactions may produce
better executions and prices. Brokerage commissions paid on transactions were as
follows: for the nine month period ended March 31, 1998 and the years ended June
30, 1997, 1996 and 1995, the Western Asset Core Portfolio paid $11,473,
$150,548, and $97,148, respectively; the Western Asset Intermediate Portfolio
paid $59,910, $50,835, and $11,655, respectively; and the Western Asset Limited
Duration Portfolio paid $7,733, $7,170 and $0 for the nine month period ended
March 31, 1998 and the year ended June 30, 1997 and the period ended June 30,
1996, respectively. No brokerage commissions were paid by any Portfolio to
affiliated persons.

                           ADDITIONAL TAX INFORMATION

GENERAL REQUIREMENTS FOR "PASS-THROUGH" TREATMENT

         In order to continue to qualify for treatment as a regulated investment
company ("RIC") under the Code, each Portfolio must distribute annually to its
shareholders at least 90% of its investment company taxable income (consisting
generally of net investment income and net short-term capital gain, if any)
("Distribution Requirement") and must meet several additional requirements. With
respect to each Portfolio, these requirements include the following: (1) the
Portfolio must derive at least 90% of its gross income each taxable year from
dividends, interest, payments with respect to securities loans and gains from
the sale or other disposition of securities or other income (including gains
from options or futures ) derived with respect to its business of investing in
securities ("Income Requirement"); (2) at the close of each quarter of the
Portfolio's taxable year, at least 50% of the value of its total assets must be
represented by cash and cash items, U.S. Government securities and other
securities, with those other securities limited, in respect of any one issuer,
to an amount that does not exceed 5% of the value of the Portfolio's total
assets; and (3) at the close of each quarter of the Portfolio's taxable year,
not more than 25% of its total assets may be invested in securities (other than
U.S. Government securities) of any one issuer.


                                      -30-


<PAGE>




         A distribution declared by a Portfolio in December of any year and
payable to shareholders of record on a date in that month will be deemed to have
been paid by the Portfolio and received by the shareholders on December 31 if
the distribution is paid by the Portfolio during the following January. Such a
distribution, therefore, will be taxable to shareholders for the year in which
that December 31 falls.

ORIGINAL ISSUE DISCOUNT

         A Portfolio may purchase debt securities issued with original issue
discount. Original issue discount that accrues in a taxable year will be treated
as income earned by the Portfolio and therefore an equivalent amount must be
distributed to satisfy the distribution requirement and avoid imposition of the
4% excise tax. Because the original issue discount earned by a Portfolio in a
taxable year may not be represented by cash income, the Portfolio may have to
dispose of other securities and use the proceeds thereof to make distributions
in amounts necessary to satisfy those distribution requirements. A Portfolio may
realize capital gains or losses from such dispositions, which would increase or
decrease the Portfolio's investment company taxable income and/or net capital
gain. In addition, any such gains may be realized on the disposition of
securities held for less than three months. Because of the Short-Short
Limitation, any such gains would reduce the Portfolio's ability to sell other
securities (and options and futures), held for less than three months that it
might wish to sell in the ordinary course of its portfolio management.

MISCELLANEOUS

         If a Portfolio invests in shares of preferred stock or otherwise holds
dividend-paying securities as a result of exercising a conversion privilege, a
portion of the dividends from the Portfolio's investment company taxable income
(whether paid in cash or reinvested in additional shares) may be eligible for
the dividends-received deduction allowed to corporations. The eligible portion
may not exceed the aggregate dividends received by the Portfolio from U.S.
corporations. However, dividends received by a corporate shareholder and
deducted by it pursuant to the dividends-received deduction are subject
indirectly to the alternative minimum tax.

         If shares of any Portfolio are sold at a loss after being held for six
months or less, the loss will be treated as long-term, instead of short-term,
capital loss to the extent of any capital gain distributions received on those
shares. Investors also should be aware that if shares are purchased shortly
before the record date for any distribution, the shareholder will pay full price
for the shares and receive some portion of the price back as a taxable dividend
or capital gain distribution.

         Dividends and interest received by a Portfolio, and gains realized by a
Portfolio on foreign securities, may be subject to income, withholding or other
taxes imposed by foreign countries and U.S. possessions that would reduce the
yield on the Portfolio's securities. Tax conventions between certain countries
and the United States may reduce or eliminate these


                                      -31-

foreign taxes, however, and foreign countries generally do not impose taxes on
capital gains in respect of investments by foreign investors.

                             PERFORMANCE INFORMATION

         Each Portfolio may, from time to time, include its total return in
marketing materials or reports to shareholders or prospective investors.
Quotations of average annual total return for a class of shares of a Portfolio
will be expressed in terms of the average annual compounded rate of return of a
hypothetical investment in that class of shares over periods of one, five and
ten years (up to the life of the class), calculated pursuant to the following
formula: P (1 + T)n = ERV (where P = a hypothetical initial payment of $1,000,
T = the average annual total return, n =


                                      -36-



<PAGE>



number of years, and ERV = the ending redeemable value of a hypothetical $1,000
payment made at the beginning of the period). All total return figures reflect
the deduction of a proportional share of Portfolio expenses on an annual basis
and assume that all dividends and other distributions are reinvested when paid.
The performance of each class of a Portfolio will differ because each class is
subject to different expenses. The performance figures for the Portfolios shown
below represent performance of the Institutional Class shares, the only class of
shares in existence throughout the relevant periods.

         The Western Asset Core Portfolio's total returns as of March 31, 1998

         The current annualized yield for the Money Market Portfolios is based
upon a specified seven-day period and is computed by determining the net change
in the value of a hypothetical account in the Portfolio. The net change in the
value of the account includes the value of dividends and of additional shares
purchased with dividends, but does not include realized gains and losses or
unrealized appreciation and depreciation. In addition, the Money Market
Portfolios may use a compound effective annualized yield quotation which is
calculated as prescribed by SEC regulations, by adding one to the base period
return (calculated as prescribed above), raising the sum to a power equal to 365
divided by 7, and subtracting one.

         Each Portfolio's performance may fluctuate daily depending upon such
factors as the average maturity of its securities, changes in investments,
changes in interest rates and variations in operating expenses. Therefore,
current performance does not provide a basis for determining future performance.
The fact that a Portfolio's performance will fluctuate and that shareholders'
principal is not guaranteed or insured should be considered in comparing the
Portfolio's performance with the performance of fixed-income investments. In
comparing the performance of a Portfolio to other investment vehicles,
consideration should be given to the investment policies of each, including the
types of investments owned, lengths of maturities of the portfolio, the method
used to compute the performance and whether there are any special charges that
may reduce the yield.

         From time to time each Portfolio may compare the performance of a Class
of Shares in advertising and sales literature to the performance of other
investment companies, groups of investment companies or various market indices.
One such market index is the S&P 500, a widely recognized, unmanaged index
composed of the capitalization-weighted average of the prices of 500 of the
largest publicly traded stocks in the U.S. The S&P 500 includes reinvestment of
all dividends. It takes no account of the costs of investing or the tax
consequences of distributions. The Portfolios invest in many securities that are
not included in the S&P 500.

         Each Portfolio may also cite rankings and ratings, and compare the
return of a Class of Shares with data published by Lipper Analytical Services,
Inc., CDA Investment Technologies, Inc., Wiesenberger Investment Company
Services, Value Line, Morningstar, and other services or publications that
monitor, compare and/or rank the performance of investment companies. Each
Portfolio may also refer in such materials to mutual fund performance rankings,
ratings, comparisons with funds having similar investment objectives, and other
mutual funds reported in independent periodicals, including, but not limited to,
FINANCIAL WORLD, MONEY MAGAZINE, FORBES, BUSINESS WEEK, BARRON'S, FORTUNE, THE
KIPLINGER LETTERS, THE WALL STREET JOURNAL, AND THE NEW YORK TIMES.

         Each Portfolio may compare the investment return of a Class of Shares
to the return on certificates of deposit and other forms of bank deposits, and
may quote from organizations that track the rates offered on such deposits. Bank
deposits are insured by an agency of the federal


                                      -38-


<PAGE>



government up to specified limits. In contrast, Portfolio shares are not
insured, the value of Portfolio shares may fluctuate, and an investor's shares,
when redeemed, may be worth more or less than the investor originally paid for
them. Unlike the interest paid on many certificates of deposit, which remains at
a specified rate for a specified period of time, the return of each Class of
Shares will vary.

         Portfolio advertisements may reference the history of Legg Mason and
its affiliates, the education and experience of the portfolio manager, and the
fact that the portfolio manager engages in a particular style of investing
(e.g., growth or value).

         In advertising, each Portfolio may illustrate hypothetical investment
plans designed to help investors meet long-term financial goals, such as saving
for a child's college education or for retirement. Sources such as the Internal
Revenue Service, the Social Security Administration, the Consumer Price Index
and Chase Global Data and Research may supply data concerning interest rates,
college tuitions, the rate of inflation, Social Security benefits, mortality
statistics and other relevant information. Each Portfolio may use other
recognized sources as they become available.

         Each Portfolio may use data prepared by Ibbotson Associates of Chicago,
Illinois ("Ibbotson") to compare the returns of various capital markets and to
show the value of a hypothetical investment in a capital market. Ibbotson relies
on different indices to calculate the performance of common stocks, corporate
and government bonds and Treasury bills.

         Each Portfolio may illustrate and compare the historical volatility of
different portfolio compositions where the performance of stocks is represented
by the performance of an appropriate market index, such as the S&P 500, and the
performance of bonds is represented by a nationally recognized bond index, such
as the Lehman Brothers Long-Term Government Bond Index.

         Each Portfolio may also include in advertising biographical information
on key investment and managerial personnel.

         Each Portfolio may advertise examples of the potential benefits of
periodic investment plans, such as dollar cost averaging, a long-term investment
technique designed to lower average cost per share. Under such a plan, an
investor invests in a mutual fund at regular intervals a fixed dollar amount
thereby purchasing more shares when prices are low and fewer shares when prices
are high. Although such a plan does not guarantee profit or guard against loss
in declining markets, the average cost per share could be lower than if a fixed
number of shares were purchased at the same intervals. Investors should consider
their ability to purchase shares through low price levels.

         Each Portfolio may discuss Legg Mason's tradition of service. Since
1899, Legg Mason and its affiliated companies have helped investors meet their
specific investment goals and have

                                      -39-


<PAGE>



provided a full spectrum of financial services. Legg Mason affiliates serve as
investment advisers for private accounts and mutual funds with assets of more
than $71 billion as of March 31, 1998.

         In advertising, each Portfolio may discuss the advantages of saving
through tax-deferred retirement plans or accounts, including the advantages and
disadvantages of "rolling over" a distribution from a retirement plan into an
IRA, factors to consider in determining whether you qualify for such a rollover,
and the other options available. These discussions may include graphs or other
illustrations that compare the growth of a hypothetical tax-deferred investment
to the after-tax growth of a taxable investment.

                  NOTES TO STATEMENT OF ASSETS AND LIABILITIES

         A. LM Institutional Fund Advisors I, Inc. (the "Corporation"), formerly
Western Asset Trust, Inc. ("Corporation"), was organized on May 16, 1990. The
Western Asset Money Market Portfolio ("Portfolio") constitutes one of the
portfolios established under the Corporation at March 31, 1998. The Portfolio
had no operations other than those matters related to its organization and
registration as an investment company under the Investment Company Act of 1940
and the sale of its shares. Western Asset Management Company ("Western Asset"),
a wholly owned subsidiary of Legg Mason, Inc. (a financial services holding
company), has provided the initial capital for the Portfolio by purchasing 1,000
shares of the Money Market Portfolio at $1.00 per share. Such shares were
acquired for investment and can be disposed of only by redemption. Legg Mason
Wood Walker, Incorporated ("Legg Mason"), a wholly owned subsidiary of Legg
Mason, Inc. and a member of the New York Stock Exchange, and Arroyo Seco, Inc.,
a wholly owned subsidiary of Western Asset, act as distributors of the
Portfolio's shares.

         B. Deferred organization and initial offering costs represent expenses
incurred in



                                      -41-

connection with the Portfolios' organization and will be amortized on a straight
line basis over five years commencing on the effective date of each Portfolio's
initial sale of shares to the public. The Portfolios have agreed to reimburse
Western Asset for the organization expenses advanced by Western Asset. The
advances are repayable on demand but must be fully repaid within five years from
the commencement of operations. The proceeds realized by Western Asset or any
holder thereof upon redemption during the amortization period of any of the
shares constituting initial capital will be reduced by a proportionate amount of
unamortized deferred organization expenses which the number of initial shares
redeemed bears to the number of initial shares then outstanding.

                        REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors of Western Asset Trust, Inc.
and Shareholders of Western Asset Money Market Portfolio

In our opinion, the accompanying statement of assets and liabilities presents
fairly, in all material respects, the financial position of Western Asset Trust
Money Market Portfolio at March 31, 1998, in conformity with generally accepted
accounting principles. This financial statement is the responsibility of the
Trust's management; our responsibility is to express an opinion on these
financial statements based on our audit. We conducted our audit of this
financial statement in accordance with generally accepted auditing standards
which require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statement is free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statement, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for the opinion expressed above.
