DESCRIPTION OF EACH PORTFOLIO, ITS INVESTMENT OBJECTIVE AND
PRINCIPAL INVESTMENT STRATEGIES

The investment objective and policies for each Portfolio are stated below. There
is no assurance a Portfolio will meet its objectives.

WESTERN ASSET GOVERNMENT MONEY MARKET PORTFOLIO
Adviser:      Western Asset
Objective:    High current income consistent with liquidity and conservation of
              principal

The Portfolio is a money market fund that seeks to maintain a net asset value of
$1.00 per share by investing in government money market instruments. To achieve
its objective, the Portfolio generally adheres to the following practices:

o    It invests only in obligations of the U.S. Government and its agencies and
     instrumentalities, repurchase agreements secured by such instruments and in
     U.S. dollar-denominated debt obligations of "supranational organizations."
     "Supranational organizations" are non-governmental entities designated or
     supported by a government or governmental entity to promote economic
     development, such as the European Community, the International Monetary
     Fund, the United Nations and the World Bank.
o    It buys instruments maturing in 397 days or less. It can also buy certain
     variable and floating rate securities.
o    It maintains a dollar-weighted average portfolio maturity of 90 days or
     less.
o    It may purchase or sell securities on a forward commitment basis.
o    It may engage in reverse repurchase agreements and other borrowings as
     permitted by applicable law.

Among the principal risks of investing in the Portfolio are Interest Rate Risk
and Credit Risk. Please see "Principal Risks" for a discussion of these and
other risks.

                                                                               3

Western Asset Money Market Portfolio

Adviser:      Western Asset
Objective:    High current income consistent with liquidity and conservation of
              principal

The Portfolio is a money market fund that seeks to maintain a net asset value of
$1.00 per share. To achieve its objective, the Portfolio generally adheres to
the following practices:

o It generally invests in money market instruments, such as:

      (i)  U.S. government obligations
     (ii)  municipal obligations
     (iii) instruments such as certificates of deposit, demand and time
           deposits, savings shares and bankers' acceptances issued by domestic
           and foreign banks and savings and loan institutions that have over $1
           billion in total assets or where the principal amount is insured by
           the Federal Deposit Insurance Corporation
     (iv)  repurchase agreements
     (v) commercial paper and other short-term investments o It invests only in
"high quality" money market instruments. "High quality"
     money market instruments are those that: (i) have received one of the two
     highest ratings by two or more Nationally Recognized Statistical Rating
     Organizations ("NRSRO"); (ii) receive one of the two highest ratings by one
     NRSRO if only one has rated the security; or (iii) if unrated, are
     determined by Western Asset to be of comparable quality.
o    It may not invest more than 5% of its total assets in the "first tier"
     securities of any one issuer (except for U.S. government obligations).
     "First tier" securities are those that: (i) have been rated in the highest
     rating category by two NRSROs; (ii) receive the highest rating by one NRSRO
     if only one has rated the security; or (iii) if unrated, are determined by
     Western Asset to be of comparable quality.
o    It may not invest more than 1% of its total assets or $1 million (whichever
     is greater) in the "second tier" securities of any one issuer. "Second
     tier" securities are all "high quality" securities that are not "first
     tier" securities.
o    It may not invest more than 5% of its total assets in "second tier"
     securities.
o    It may invest only in U.S. dollar-denominated securities. These include
     foreign investments denominated in U.S. dollars.
o    It may engage in reverse repurchase agreements and make other borrowings.
o    It buys money market securities maturing in 397 days or less. It can also
     buy certain variable and floating rate securities.
o    It may purchase or sell securities on a forward commitment basis.
o    It maintains a dollar-weighted average portfolio maturity of 90 days or
     less.

Among the principal risks of investing in the Portfolio are Interest Rate Risk
and Credit Risk. Please see "Principal Risks" for a discussion of these and
other risks.

WESTERN ASSET INTERMEDIATE PORTFOLIO, WESTERN ASSET INTERMEDIATE PLUS PORTFOLIO,
WESTERN ASSET CORE PORTFOLIO, WESTERN ASSET CORE PLUS PORTFOLIO
Advisers:     Western Asset and WAGM (non-U.S. portions of Intermediate Plus and
              Core Plus Portfolios)
Objective:    Maximize  total  return, consistent with prudent investment
              management and liquidity needs, by investing to obtain the average
              duration specified for each Portfolio

Each of these Portfolios invests in a portfolio of fixed income securities of
various maturities. To achieve their objectives, the Portfolios invest primarily
in:

o    U.S. Government obligations
o    mortgage- and other asset-backed securities
o    U.S. dollar-denominated obligations of foreign governments, international
     agencies or supranational organizations
o    U.S. dollar-denominated fixed income securities of non-governmental
     domestic or foreign issuers

4
<PAGE>
In addition to the foregoing principal investment strategies, the Portfolios are
also permitted to:

o    purchase other securities and instruments, including:

     (i)      preferred stocks
     (ii)     structured notes
     (iii)    municipal obligations
     (iv)     convertible securities
     (v)      pay-in-kind securities and zero coupon bonds
     (vi) certificates of deposit, time deposits and bankers' acceptances issued
      by domestic and foreign banks
     (vii) commercial paper and other short-term investments o invest up to 25%
of their total assets in the securities of foreign issuers o buy or sell futures
contracts and options for both hedging and non-hedging
     purposes, including for purposes of enhancing returns o buy or sell
securities on a forward commitment basis o lend its portfolio securities o
engage in foreign currency exchange transactions o engage in repurchase
agreements and reverse repurchase agreements o borrow money for temporary or
emergency purposes

Each of the Portfolios may buy and sell investments relatively often, which
involves higher brokerage commissions and other expenses, and may increase taxes
payable by shareholders.

Each Portfolio in this group differs from the others in terms of its investment
policies regarding its target dollar weighted average duration, and the two
"Plus" Portfolios, the Intermediate Plus and Core Plus, differ from the other
Portfolios in terms of their policies with respect to U.S. dollar-denominated
securities and the credit quality of their investments. These differences are
summarized in the following table. "Duration" refers to the range within which
the dollar weighted average duration of a Portfolio is expected to fluctuate.
With respect to the Core and Core Plus Portfolios, the average duration is
expected to range within 20% of the duration of the domestic bond market as a
whole (normally four to six years, although this may vary) as measured by
Western Asset. "Foreign Currency Exposure" refers to whether a Portfolio
presently intends to limit its investments to U.S. dollar-denominated
securities. "Credit Quality" refers to the percentage of a Portfolio's net
assets that may be invested in debt securities that are rated, at the time of
purchase, below investment grade, but at least B or higher by an NRSRO or, if
unrated, determined by the Adviser to be of comparable quality. The continued
holding of securities downgraded below investment grade or, if unrated,
determined by Western Asset to be of comparable quality, will be evaluated by
Western Asset on a case by case basis.

Among the principal risks of investing in these Portfolios are Interest Rate
Risk, Credit Risk,CallRisk, Special Risks of Mortgage-Backed and Asset-Backed
Securities, Foreign Securities Risk, Borrowing Risk, Derivatives Risk and
Hedging Risk. In addition to those risks, Special Risks of High Yield
Securities, Liquidity Risk and Currency Risk are among the principal risks of
investing in the Intermediate Plus and Core Plus Portfolios. Please see
"Principal Risks" for a discussion of these and other risks.

WESTERN ASSET HIGH YIELD PORTFOLIO
Adviser:    Western Asset
Objective:  Maximize total return, consistent with prudent investment management

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 that are
rated below investment grade at the time of purchase 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.

To achieve its objective, the Portfolio may also make other investments,
including:

o mortgage- and other asset-backed securities o municipal obligations o variable
and floating rate debt securities o commercial paper and other short-term
investments o corporate obligations ("Corporate obligations" include preferred
stock,
     convertible securities, zero coupon securities and pay-in-kind securities.)
o    common stocks and warrants
o    certificates of deposit, fixed time deposits and bankers' acceptances
     issued by domestic banks

 The Portfolio is also permitted to:

o    invest up to 25% of its total assets in foreign currency-denominated
     foreign securities
o    buy or sell futures contracts and options for both hedging and non-hedging
     purposes, including for purposes of enhancing returns
o engage in foreign currency exchange transactions o lend its portfolio
securities o borrow money for temporary or emergency purposes o buy or sell
securities on a forward commitment basis o engage in repurchase agreements and
reverse repurchase agreements

 The Portfolio may buy and sell investments relatively often, which involves
higher brokerage commissions and other expenses, and may increase taxes payable
by shareholders.

Among the principal risks of investing in the Portfolio are Interest Rate Risk,
Credit Risk,CallRisk, Special Risks of High Yield Securities, Special Risks of
Mortgage-Backed and Asset-Backed Securities, Market Risk, Foreign Securities
Risk, Liquidity Risk, Borrowing Risk, Emerging Markets Risk, Currency Risk,
Derivatives Risk and Hedging Risk. Please see "Principal Risks" for a discussion
of these and other risks.

WESTERN ASSET NON-U.S. FIXED INCOME PORTFOLIO
Adviser:    WAGM
Objective:  Maximize total return, consistent with prudent investment management

Under normal market conditions, the Portfolio invests at least 75% of its total
assets in debt and fixed income securities denominated in major foreign
currencies. WAGM anticipates that, under normal market conditions, all or
substantially all of the Portfolio's assets will be invested in securities of
foreign issuers and that these foreign issuers will represent at least three
foreign countries. Under current market conditions, the Portfolio expects that
substantially all of its currency risk will be hedged to U.S. dollars.

6
<PAGE>
To achieve its objective, the Portfolio may invest in a variety of securities,
including:

o    U.S. dollar-denominated or foreign currency-denominated obligations of
     foreign governments, international agencies or supranational entities
o    foreign currency exchange-related securities, including foreign currency
     warrants
o U.S. Government obligations o mortgage- and other asset-backed securities o
variable and floating rate debt securities o commercial paper and other
short-term investments o corporate obligations o certificates of deposit, fixed
time deposits and bankers' acceptances o loan participations and assignments o
indexed securities and structured notes o repurchase agreements

The Portfolio may also:

o    engage in reverse repurchase agreements
o    borrow money for temporary or emergency purposes
o    buy or sell futures contracts and options for both hedging and non-hedging
     purposes, including for purposes of enhancing returns
o    buy or sell foreign currencies, foreign currency options, or foreign
     currency futures contracts and related options
o    enter into foreign currency forward contracts for hedging and non-hedging
     purposes, including for purposes of enhancing returns
o    loan its portfolio securities

The Portfolio does not currently intend to invest in securities that are rated
at the time of purchase below investment grade, although it may do so if market
conditions are favorable. The Portfolio is "non-diversified" within the meaning
of the Investment Company Act. See "Principal Risks--Non-Diversification." WAGM
anticipates that from time to time over 25% of the Portfolio's assets may be
invested in securities of issuers located in a single country. Because the
Portfolio may concentrate a significant portion of its investments in a single
country or currency, it will be more susceptible to factors adversely affecting
such currency or issuers within that country than would a more diversified
portfolio of securities. The Portfolio may buy and sell investments relatively
often, which involves higher brokerage commissions and other expenses, and may
increase taxes payable by shareholders.

Among the principal risks of investing in the Portfolio are Interest Rate Risk,
Credit Risk,CallRisk, Special Risks of High Yield Securities, Special Risks of
Mortgage-Backed and Asset-Backed Securities, Market Risk, Foreign Securities
Risk, Emerging Markets Risk, Currency Risk, Borrowing Risk, Derivatives Risk,
Liquidity Risk and Hedging Risk. Please see "Principal Risks" for a discussion
of these and other risks.

WESTERN ASSET GLOBAL STRATEGIC INCOME PORTFOLIO
Advisers:     WAGM (non-U.S. portion) and Western Asset (U.S. portion)
Objective:    Income and capital appreciation

To achieve its investment objective, the Portfolio invests primarily in various
types of U.S. dollar-denominated and foreign currency-denominated fixed income
securities, including:

o    U.S. and foreign corporate fixed income securities
o    Debt obligations of corporate and governmental issuers in emerging market
     countries (These 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.)
o    sovereign debt obligations of developed nations, including those of the
     United States
o    debt obligations of "supranational organizations"
o    mortgage- and other asset-backed securities

                                                                               7
<PAGE>
The Portfolio may invest in a variety of other securities, including:

o    foreign currency exchange-related securities, including foreign currency
     warrants
o variable and floating rate debt securities o commercial paper and other
short-term investments o municipal obligations o certificates of deposit, fixed
time deposits and bankers' acceptances o loan participations and assignments o
indexed securities and structured notes o repurchase agreements

The Portfolio may invest up to 60% 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 or Western Asset. These
securities are commonly known as "junk bonds" or "high yield bonds." The
Portfolio may buy and sell investments relatively often, which involves higher
brokerage commissions and other expenses, and may increase taxes payable by
shareholders.

The Portfolio may also:

o engage in reverse repurchase agreements o borrow money for temporary or
emergency purposes o loan its portfolio securities o buy or sell futures
contracts and options for both hedging and non-hedging
     purposes, including for purposes of enhancing returns
o    buy or sell foreign currencies, foreign currency options, or foreign
     currency futures contracts and related options
o    enter into foreign currency forward contracts for hedging and non-hedging
     purposes, including for purposes of enhancing returns

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. Because the Portfolio may concentrate a significant
portion of its investments in a single country or currency, it will be more
susceptible to factors adversely affecting issuers within that country or
currency than would a more diversified portfolio of securities.

The Portfolio is "non-diversified" within the meaning of the Investment Company
Act. See "Principal Risks--Non-Diversification."

Among the principal risks of investing in the Portfolio are Interest Rate Risk,
Credit Risk, Call Risk, Special Risks of High Yield Securities, Special Risks of
Mortgage-Backed and Asset-Backed Securities, Foreign Securities Risk, Emerging
Markets Risk, Currency Risk, Borrowing Risk, Derivatives Risk, Liquidity Risk
and Hedging Risk. Please see "Principal Risks" for a discussion of these and
other risks.

WESTERN ASSET ENHANCED EQUITY PORTFOLIO
Adviser:      Western Asset
Objective:    Long-term total return

The Portfolio's assets will be comprised of two components: an equity component
and a fixed income component.

o    The equity component will generally maintain full exposure to the U.S.
     equity market as represented by the S&P 500 Index (the "Index").
o    The fixed income component will try to generate interest and gains in
     excess of the Portfolio's expenses, including transaction costs related to
     its investments.

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, but not exclusively, on whether the fixed income component
has earned sufficient amounts to offset the Portfolio's expenses. Up to 10% of
the Portfolio's net assets may be invested in securities rated below investment
grade at the time of purchase or unrated securities of comparable quality at the
time of purchase (commonly known as "junk bonds" or "high yield bonds") and up
to 20% of its net assets may be invested in foreign securities. The Portfolio
may buy and sell investments relatively often, which involves higher brokerage
commissions and other expenses, and may increase taxes payable by shareholders.
The following information summarizes the investment practices of the Portfolio's
two components.

8
<PAGE>
Equity Component

The Portfolio's equity component invests primarily in: (i) common stocks that
are represented in the Index ("S&P stocks") and (ii) 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 Equity Component of the Portfolio adheres to the following practices:

o    it may invest in any combination of S&P stocks and S&P derivatives.
o    it currently plans to invest predominantly, and likely exclusively, in S&P
     derivatives.
o    it will not be limited to purchasing S&P stocks in the same proportion as
     such stocks are weighted in the Index.
o    it will seek to remain invested in S&P stocks and S&P derivatives even when
     the Index is declining.

The Index is composed of 500 selected common stocks, most of which are listed on
the New York Stock Exchange. Standard and Poor's ("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. The Portfolio is
neither sponsored by nor affiliated with S&P.

Fixed Income Component

The fixed income component will invest primarily in the following types of fixed
income securities:

o    U.S. Government obligations
o securities of non-governmental domestic or foreign issuers o municipal
securities o mortgage- and other asset-backed securities o preferred stocks o
obligations of foreign governments, international agencies or supranational
     entities

The fixed income component may also invest in other securities or instruments,
including:

     (i)   certificates of deposit, time deposits and bankers' acceptances
           issued by domestic and foreign banks
     (ii) commercial paper and other short-term investments (iii) engage in
     repurchase agreements, reverse repurchase agreements and
           other borrowings
     (iv) purchase or sell futures contracts and options (v) engage in foreign
     currency exchange transactions

Among the principal risks of investing in the Portfolio are Market Risk,
Interest Rate Risk, Credit Risk,CallRisk, Special Risks of High Yield
Securities, Special Risks of Mortgage-Backed and Asset-Backed Securities,
Foreign Securities Risk, Emerging Markets Risk, Currency Risk, Borrowing Risk,
Derivatives Risk and Hedging Risk. Please see "Principal Risks" for a discussion
of these and other risks.

LM VALUE INSTITUTIONAL PORTFOLIO
Adviser:      LMFA
Objective:    Long-term growth of capital

The Portfolio invests primarily in equity securities (including common and
preferred stocks), and securities convertible into equity securities, that, in
the Adviser's opinion, offer the potential for capital growth. The Adviser
follows a value discipline in selecting securities, and therefore seeks to
purchase securities at large discounts to the Adviser's assessment of their
intrinsic value. Intrinsic value, according to the Adviser, is the value of the
company measured, to different extents depending on the type of company, on
factors such as, but not limited to, the discounted value of its projected
future free cash flows, the company's ability to earn returns on capital in
excess of its cost of capital, private market values of similar companies, the
value of its assets, and the costs to replicate the business. Qualitative
factors, such as an assessment of the company's products, competitive
positioning, strategy, industry economics and dynamics, regulatory frameworks
and more, are also important. Securities may be undervalued due to uncertainty
arising from the availability of accurate information, economic growth and
change, changes in competitive conditions, technological change, changes in
government policy or geo-political dynamics, and more. The Adviser takes a
long-term approach to investing, generally characterized by long holding periods
and low portfolio turnover. The Portfolio generally invests in companies with
market capitalizations greater than $5 billion, but may invest in companies of
any size.

                                                                               9

The Adviser typically sells a security when, in the Adviser's assessment, the
security no longer appears to offer a long-term above average risk-adjusted rate

invested in convertible and/or debt securities rated below investment grade,
i.e., not rated at least BBB by Standard & Poor's or Baa by Moody's Investors
Service, Inc. or, if unrated by those entities, deemed by the Adviser to be of
comparable quality, and commonly referred to as junk bonds.

For temporary purposes, or when cash is temporarily available, the Portfolio may
invest without limit in investment grade, short-term debt instruments, including
government, corporate and money market securities. The Portfolio may not achieve
its investment objective when so invested.

LM SPECIAL INVESTMENT INSTITUTIONAL PORTFOLIO
Adviser:      LMFA
Objective:    Capital appreciation

The Portfolio invests primarily in equity securities, and securities convertible
into equity securities, of companies whose market capitalizations are typically
classified as small to mid-sized. The Adviser defines small to mid-sized
companies as those below the top 500 U.S. companies in terms of market
capitalization. It also invests in "special situations" without regard to market
capitalization. Special situations are companies undergoing unusual or possibly
one-time developments that, in the opinion of the Adviser, make them attractive
for investment. Such developments may include actual or anticipated: sale or
termination of an unprofitable part of the company's business; change in the
company's management or in management's philosophy; a basic change in the
industry in which the company operates; introduction of new products or
technologies; or the prospect or effect of acquisition or merger activities.

The Adviser follows a value discipline in selecting securities, and therefore
seeks to purchase securities at large discounts to the Adviser's assessment of
their intrinsic value. Intrinsic value, according to the Adviser, is the value
of the company measured, to different extents depending on the type of company,
on factors such as, but not limited to, the discounted value of its projected
future free cash flows, the company's ability to earn returns on capital in
excess of its cost of capital, private market values of similar companies, the
value of its assets, and the costs to replicate the business. Qualitative
factors, such as an assessment of the company's products, competitive
positioning, strategy, industry economics and dynamics, regulatory frameworks
and more, are also important. Securities may be undervalued due to uncertainty
arising from the availability of accurate information, economic growth and
change, changes in competitive conditions, technological change, changes in
government policy or geo-political dynamics, and more.

The Portfolio also invests in debt securities of companies having one or more of
the above characteristics. The Portfolio may invest up to 35% of its net assets
in debt securities rated below investment grade, i.e., rated below BBB/Baa (or,
if unrated, determined by the Adviser to be of comparable quality) and commonly
referred to as junk bonds. The Portfolio may invest up to 20% of its total
assets in securities of companies involved in actual or anticipated
reorganizations or restructurings.

The Adviser typically sells a security when, in the Adviser's assessment, the
security no longer appears to offer a long-term above average risk-adjusted rate
of return, when a more compelling investment opportunity is found, or when the
investment basis no longer applies.

For temporary defensive purposes, or when cash is temporarily available, the
Portfolio may invest without limit in investment grade, short-term debt
instruments, including government, corporate and money market securities. The
Portfolio may not achieve its investment objective when so invested.

Among the principal risks of investing in the Portfolio are Market Risk,
Interest Rate Risk, Credit Risk, Call Risk, Special Risks of High Yield
Securities, Borrowing Risk, and Hedging Risk. Please see "Principal Risks" for a
discussion of these and other risks.

LM TOTAL RETURN INSTITUTIONAL PORTFOLIO
Adviser:      LMFA
Objective:    Capital appreciation and current income in order to achieve an
              attractive total investment return consistent with reasonable risk

The Portfolio invests primarily in securities that, in the Adviser's opinion,
offer the potential for long-term capital growth and attractive current income.
The Portfolio invests primarily in common stocks, debt securities, and
securities convertible into common stocks, but is not limited to these types of
securities. The Portfolio may invest in securities that do not pay current
income but do, in the Adviser's opinion, offer prospects for capital
appreciation and/or future income. The Adviser follows a value discipline in
selecting securities, and therefore seeks to purchase securities at large
discounts to the Adviser's assessment of their intrinsic value. Intrinsic value,
according to the Adviser, is the value of the company measured, to different
extents depending on the type of company, on factors such as, but not limited
to, the discounted value of its projected future free cash flows, the company's
ability to earn returns on capital in excess of its costs of capital, private
market values of similar companies, the value of its assets, and the costs to
replicate the business. Qualitative factors, such as an assessment of the
company's products, competitive positioning, strategy, industry economics and
dynamics, regulatory frameworks and more, are also important. Securities may be
undervalued due to uncertainty arising from the availability of accurate
information, economic growth and change, changes in competitive conditions,
technological change, changes in government policy or geo-political dynamics,
and more. The Portfolio may invest in companies of any size.

The Adviser typically sells a security when, in the Adviser's assessment, the
security no longer appears to offer long-term attractive total returns at
reasonable risk, when a more compelling investment opportunity is found, or when
the investment basis no longer applies. The Portfolio may invest in money market
securities for temporary defensive purposes or when cash is temporarily
available. The Portfolio may not achieve its investment objective when so
invested. Consistent with the investment objective, the Portfolio may also
invest in debt securities when the Adviser believes the return on such
securities may equal or exceed the return on equity securities. The Portfolio
may invest in debt securities of any maturity of both foreign and domestic
issuers without regard to rating, and may invest its assets in debt securities
without regard to a percentage limit. The Adviser currently anticipates that
under normal market conditions the Portfolio will invest no more than 50% of its
total assets in intermediate-term and long-term debt securities and no more than
5% of its total assets in debt securities not rated investment grade (commonly
referred to as junk bonds).

Among the principal risks of investing in the Portfolio are Market Risk,
Interest Rate Risk, Credit Risk,CallRisk, Special Risks of High Yield
Securities, Liquidity Risk, Borrowing Risk, Foreign Securities Risk, Currency
Risk and Hedging Risk. Please see "Principal Risks" for a discussion of these
and other risks.

LM BALANCED INSTITUTIONAL PORTFOLIO
Adviser:      LMFA
Objective:    Long-term capital appreciation and current income

The Portfolio is a "fund of funds" which is comprised of two separate investment
components: an equity component and a fixed income component. The equity
component will consist solely of Institutional Class shares of the LM Value
Institutional Portfolio ("Value Institutional Portfolio"), a series of LM
Institutional Fund Advisors II, Inc., while the fixed income component will
consist solely of Institutional Class shares of the Western Asset Core Portfolio
("Core Portfolio"), a series of LM Institutional Fund Advisors I, Inc. The
investment objectives, principal investment strategies and related risks of the
Core Portfolio and the Value Institutional Portfolio are described elsewhere in
this Prospectus.

LMFA, the Portfolio's Adviser, will be responsible for allocating assets between
the two components. LMFA currently anticipates that under normal market
conditions approximately 60% of the Portfolio's total assets will be allocated
to the equity component and approximately 40% will be allocated to the fixed
income component. However, LMFA reserves the right to vary these percentages, as
it deems appropriate and market opportunities arise, subject to the limitation
that, under normal market conditions, at least 25% of the Portfolio's total
assets will be allocated to the fixed income component. The Portfolio may also
hold cash or other short-term investments.

                                                                              11
<PAGE>
BATTERYMARCH U.S. MIDCAPITALIZATION EQUITY PORTFOLIO
Adviser:      Batterymarch
Objective:    Long-term capital appreciation

Under normal market conditions, the Portfolio will invest at least 65% of its
total assets in equity securities of companies with medium market
capitalizations domiciled, or having their principal activities, in the United
States. The Adviser defines medium market capitalization companies as those with
market capitalizations similar, in its judgment, to the market capitalization of
companies in the Standard & Poor's MidCap 400 Index, determined at the time of
the Portfolio's investment. The S&P MidCap 400 Index is a market weighted
composite index of 400 stocks in the middle capitalization sector of the U.S.
equities market. A company that was a medium market capitalization company at
the time of the Portfolio's investment will continue to be treated as such for
purposes of the 65% test, even if its market capitalization is no longer similar
to that of companies in the S&P MidCap 400 Index.

Equity securities include common stock, preferred stock, securities convertible
into or exchangeable for common stock, rights and warrants to acquire such
securities and substantially similar forms of equity with comparable risk. The
Portfolio may also invest in securities of companies in the form of American
Depository Receipts, which are typically dollar-denominated instruments traded
on an exchange in the United States.

The Adviser uses a bottom-up, quantitative stock selection process. The
cornerstone of this process is a proprietary stock selection model that ranks
the stocks in the Portfolio's investable universe by relative attractiveness.
The quantitative factors within this model reflect a style neutral investment
philosophy and are intended to measure growth, value, fundamental expectations
and technical indicators.

In addition to its principal investment strategies, the Portfolio may engage in
other transactions. For example, although the Portfolio expects to remain
substantially fully invested in equity securities, the Portfolio may invest in
debt or fixed income securities, cash and money market instruments, including
repurchase agreements. Under normal market conditions, up to 5% of the
Portfolio's total assets may be invested in fixed income securities rated below
investment grade or, if unrated, determined by the Adviser to be of comparable
quality. The Portfolio may also engage in reverse repurchase agreement
transactions and other borrowings, purchase restricted and illiquid securities,
lend its portfolio securities, invest in securities of other investment
companies, engage in foreign currency exchange transactions and engage in
futures and options transactions.

Among the principal risks of investing in the Portfolio are Market Risk,
Interest Rate Risk, Credit Risk, Borrowing Risk, Liquidity Risk, Derivatives
Risk, Special Risks of High Yield Securities and Hedging Risk. Please see
"Principal Risks" for a discussion of these and other risks.

BATTERYMARCH U.S. SMALL CAPITALIZATION EQUITY PORTFOLIO
Adviser:      Batterymarch
Objective:    Long-term capital appreciation

Under normal market conditions, the Portfolio will invest at least 65% of its
total assets in equity securities of companies with small market capitalizations
domiciled, or having their principal activities, in the United States. The
Adviser defines small market capitalization companies as those whose market
capitalizations are similar, in its judgment, to the market capitalization of
companies in the Russell 2000 Index, determined at the time of the Portfolio's
investment. The Russell 2000 Index is a capitalization-weighted broad based
index of 2000 small capitalization U.S. companies. A company that was a small
market capitalization company at the time of the Portfolio's investment will
continue to be treated as such for purposes of the 65% test, even if its market
capitalization is no longer similar to that of companies in the Russell 2000
Index.

Equity securities include common stock, preferred stock, securities convertible
into or exchangeable for common stock, rights and warrants to acquire such
securities and substantially similar forms of equity with comparable risk. The
Portfolio may also invest in securities of companies in the form of American
Depository Receipts which are typically dollar-denominated instruments traded on
an exchange in the United States.

The Adviser uses a bottom-up, quantitative stock selection process. The
cornerstone of this process is a proprietary stock selection model that ranks
the stocks in the Portfolio's investable universe by relative attractiveness on
a daily basis. The quantita-

12

tive factors within this model reflect a style neutral investment philosophy and
are intended to measure growth, value, fundamental expectations and technical
indicators.

In addition to its principal investment strategies, the Portfolio may engage in
other transactions. For example, although the Portfolio expects to remain
substantially fully invested in equity securities, the Portfolio may invest in
debt or fixed income securities, cash and money market instruments, including
repurchase agreements. Under normal market conditions, up to 5% of the
Portfolio's total assets may be invested in fixed income securities rated below
investment grade or, if unrated, determined by the Adviser to be of comparable
quality. The Portfolio may also engage in reverse repurchase agreement
transactions and other borrowings, purchase restricted and illiquid securities,

companies, engage in foreign currency exchange transactions and engage in
futures and options transactions.

BATTERYMARCH INTERNATIONAL EQUITY PORTFOLIO
Adviser:      Batterymarch
Objective:    Long-term total return

Under normal market conditions, the Portfolio will invest substantially all of
its assets, but in any event at least 65% of its total assets, in non-U.S.
equity securities.

The primary focus of the Adviser is stock selection, with a secondary focus on
country allocation. The Adviser uses a bottom-up, quantitative stock selection
process for the developed markets portion of the Portfolio's portfolio. The
cornerstone of this process is a proprietary stock selection model that ranks
the 2,800 stocks in the Portfolio's investable universe by relative
attractiveness on a daily basis. The quantitative factors within this model are
intended to measure growth, value, fundamental expectations and technical
indicators (i.e., supply and demand).

Country allocation for the developed markets portion of the Portfolio is based
on rankings generated by the Adviser's proprietary country model. The Adviser
examines securities from over 20 international stock markets, with emphasis on
several of the largest: Japan, United Kingdom, France, Canada and Germany.

The Portfolio may invest up to 35% of its total assets in emerging market equity
securities. The Adviser's investment strategy for the emerging markets portion
of the Portfolio represents a distinctive combination of tested quantitative
methodology and traditional fundamental analysis. The emerging markets
allocation focuses on higher-quality, dominant companies which the Adviser
believes to have strong growth prospects and reasonable valuations. Country
allocation for the emerging markets portion of the Portfolio also combines
quantitative and fundamental approaches.

The Portfolio will normally be invested across a broad range of industries and
across a number of countries, consistent with the objective of maximum total
return. However, more than 25% of the Portfolio's total 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 Japan and the United Kingdom.
Because the Portfolio may concentrate a significant portion of its investments
in a single country or currency, it will be more susceptible to factors
adversely affecting such currency or issuers within that country than would a
more diversified portfolio of securities.

The Portfolio may invest without limit in cash and money market instruments,
including repurchase agreements, in circumstances when cash is temporarily
available, or for temporary defensive purposes when the Adviser believes such
action is warranted by abnormal market or economic situations. The Portfolio may
not achieve its investment objectives when so invested. Up to 5% of the
Portfolio's total assets may be rated below investment grade or, if unrated,
determined by the Adviser to be below investment grade. The Adviser may also
seek to enhance portfolio returns through active currency hedging strategies,
although there can be no assurances that such strategies will be pursued or, if
pursued, will be successful.

Among the principal risks of investing in the Portfolio are Market Risk, Foreign
Securities Risk, Emerging Markets Risk, Currency Risk, Interest Rate Risk,
Credit Risk, Call Risk, Special Risks of High Yield Securities, Borrowing Risk,
Derivatives Risk and Hedging Risk. Please see "Principal Risks" for a discussion
of these and other risks.

BATTERYMARCH EMERGING MARKETS PORTFOLIO
Adviser:      Batterymarch
Objective:    Long-term capital appreciation

Under normal market conditions, the Portfolio will invest substantially all of
its assets, but in any event at least 65% of its total assets, in equity
securities and convertible securities of emerging market issuers. Emerging
market countries are those countries having less fully developed economic and
political systems and include any country: (i) having an "emerging stock market"
or considered a "frontier market" as defined by the International Finance
Corporation; (ii) with low- to middle-income economies according to the
International Bank for Reconstruction and Development ("World Bank"); (iii)
listed in World Bank publications as developing; or (iv) included in the Morgan
Stanley Capital International (MSCI) Emerging Markets published index. Emerging
market equity securities include common stock, preferred stock, securities
convertible into common stock, rights and warrants to acquire such securities
and substantially similar forms of equity with comparable risk characteristics
that are: (1) publicly traded on emerging market stock exchanges, or whose
principal trading market is over-the-counter (i.e., off-exchange) in an emerging
market country; (2) securities denominated in any currency if issued by
companies to finance operations in an emerging market country; (3) securities of
companies that derive a substantial portion (i.e., in excess of 50%) of their
total revenues from goods or services produced in, or sales made in, emerging
market countries; (4) securities of companies organized under the laws of an
emerging market country or region, which are publicly traded in securities
markets elsewhere; or (5) American depositary receipts ("ADRs") (or similar
instruments) with respect to the foregoing.

The Portfolio intends to invest in Asia, Latin America, the Indian Subcontinent,
Southern and Eastern Europe, the Middle East and Africa, although it may not
invest in all these markets at all times and may not invest in any particular
market when it deems investment in that country or region to be inadvisable.

More than 25% of the Portfolio's total assets may be invested in securities of
issuers located in a single country. Because the Portfolio may concentrate a
significant portion of its investments in a single country or currency, it will
be more susceptible to factors adversely affecting such currency or issuers
within that country than would a more diversified portfolio of securities.

The Adviser focuses on higher-quality, dominant emerging markets companies which
the Adviser believes to have strong growth prospects and reasonable valuations,
selected from an investable universe of approximately 1,000 stocks. The
Adviser's emerging markets investment strategy represents a distinctive
combination of quantitative methodology and traditional fundamental analysis.
Traditional "on-the-ground" fundamental research is combined by the Adviser with
tested quantitative valuation disciplines in those markets where reliable data
is available. In determining country allocation, the Adviser also merges
quantitative and fundamental approaches.

The Portfolio may invest without limit in cash and money market instruments,
including repurchase agreements, in circumstances when cash is temporarily
available, or for temporary defensive purposes when the Adviser believes such
action is warranted by abnormal market or economic situations. The Portfolio may
not achieve its investment objective when so invested. Up to 10% of the
Portfolio's total assets may be rated below investment grade or, if unrated,
determined by the Adviser to be below investment grade (i.e., rated below
BBB/Baa and commonly referred to as junk bonds).

Among the principal risks of investing in the Portfolio are Market Risk, Foreign
Securities Risk, Emerging Markets Risk, Currency Risk, Interest Rate Risk,
Credit Risk, Call Risk, Special Risks of High Yield Securities, Borrowing Risk,
Derivatives Risk and Hedging Risk. Please see "Principal Risks" for a discussion
of those and other risks.

PRINCIPAL RISKS

IN GENERAL

At any time, your investment in a mutual fund may be worth more or less than the
price you originally paid for it. You may lose money by investing in any of
these Portfolios because: (1) the value of the investments it owns changes,
sometimes rapidly and unpredictably; (2) the Portfolio is not successful in
reaching its goal because of its strategy or because it did not implement its
strategy properly; or (3) unforeseen occurrences in the securities markets
negatively affect the Portfolio.

14
<PAGE>
An investment in the Western Asset government Money Market and Western Asset
MoneyMarket Portfolios is not a deposit of a bank and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency. Although the Western Asset Government Money Market and Western Asset
Money Market Portfolios seek to preserve the value of your investment at $1.00
per share, it is possible to lose money by investing in these Portfolios.

The following risks apply to the Portfolios. You should read this section
carefully before you invest in order to learn more about the Portfolio in which
you will invest.

MARKET RISK

Certain of the Portfolios may invest, directly or indirectly, substantially all
of their assets in equity securities. Prices of equity securities generally
fluctuate more than those of other securities. A Portfolio may experience a
substantial or complete loss on an individual stock. Market risk may affect a
single issuer, industry or section of the economy or may affect the market as a
whole. The Batterymarch International Equity Portfolio and the Batterymarch
Emerging Markets Portfolio invest primarily in foreign equity securities.
Foreign securities have additional risks, see "Foreign Securities Risk" and
"CurrencyRisk" below.

Securities of "small cap" companies, such as those in which the Batterymarch
U.S. SmallCapitalizationEquity Portfolio may invest, entail special risks. Such
companies often have limited operating histories and may have more restricted
product lines or more limited financial resources than larger, more established
companies. For these and other reasons, they may be more severely affected by
economic downturns or other adverse developments than are larger, more
established companies. Securities of "small cap" companies may be traded
"over-the-counter" and often trade less frequently and in more limited volume,
may be subject to greater volatility and may be more difficult to value than
securities of larger, more established companies. "Small cap" companies are
often involved in actual or anticipated reorganizations or restructurings, which
involve special risks, including difficulty in obtaining information as to the
financial condition of such companies and the fact that market prices of such
companies' securities are subject to sudden and erratic price volatility. The
securities of "mid-sized" companies, such as those in which the Batterymarch
U.S. MidCapitalization Equity Portfolio may invest, share many of these same
risks.

FOREIGN SECURITIES RISK

Investments in foreign securities (including those denominated in U.S. dollars)
involve certain risks not typically associated with investments in domestic
issuers. The values of foreign securities are subject to economic and political
developments in the countries and regions where the companies operate, such as
changes in economic or monetary policies, and to changes in exchange rates.
Values may also be affected by restrictions on receiving the investment proceeds
from a foreign country.

In general, less information is publicly available about foreign companies than
about U.S. companies. Foreign companies are generally not subject to the same
accounting, auditing and financial reporting standards as are U.S. companies.

Some securities issued by foreign governments or their subdivisions, agencies
and instrumentalities may not be backed by the full faith and credit of the
foreign government. Even where a security is backed by the full faith and credit
of a foreign government, it may be difficult for a Portfolio to pursue its
rights against a foreign government in that country's courts. Some foreign
governments have defaulted on principal and interest payments.

In addition, a Portfolio's investments in foreign securities may be subject to
the risk of nationalization or expropriation of assets, imposition of currency
exchange controls or restrictions on the repatriation of foreign currency,
complications with the European markets' conversion to the Euro, confiscatory
taxation, political or financial instability and diplomatic developments which
could effect the value of a Portfolio's investments in certain foreign
countries. Dividends or interest on, or proceeds from the sale of, foreign
securities may be subject to foreign withholding taxes, and special U.S. tax
considerations may apply.

EMERGING MARKETS RISK

The risks of foreign investment are greater for investments in emerging markets.
Among others, these types of investments can include not only equity securities,
but also "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. Emerging market countries
typically have economic and political systems that are less fully developed, and
can be expected to be less stable than those of more advanced countries. For
example, the economies of such countries can be subject to rapid and
unpredictable

                                                                              15
<PAGE>
rates of inflation or deflation. Low trading volumes may result in a lack of
liquidity and in price volatility. Emerging market countries may have policies
that restrict investment by foreigners, or that prevent foreign investors from
withdrawing their money at will.

Because some of the Portfolios may invest a significant amount of their total
assets in emerging market securities, investors should be able to tolerate
sudden and sometimes substantial fluctuations in the value of their investments.
An investment in any Portfolio that invests in emerging market securities, which
includes the Batterymarch Emerging Markets Portfolio, the Batterymarch
International Equity Portfolio, the Western Asset High Yield Portfolio, the
Western Asset Non-U.S. Fixed Income Portfolio and the Western Asset Global
Strategic Income Portfolio, should be considered speculative.

CURRENCY RISK

Because certain Portfolios may invest significantly in securities denominated in
foreign currencies, their value can be affected by changes in the rates of
exchange between those currencies and the U.S. dollar. Currency exchange rates
can be volatile and affected by, among other factors, the general economics of a
country, the actions of the U.S. and foreign governments or central banks, the
imposition of currency controls, and speculation. A security may be denominated
in a currency that is different from the currency where the issuer is domiciled.

In addition to the policies described elsewhere in this Prospectus, the
Portfolios may from time to time hedge a portion of their currency risk, using a
variety of techniques, including currency futures, forwards, or options.
However, these instruments may not always work as intended, and in specific
cases a Portfolio may be worse off than if it had not used a hedging instrument.
For most emerging market currencies, there are not suitable hedging instruments
available. See "Hedging Risk" below.

INTEREST RATE RISK

Each Portfolio may be subject to interest rate risk, which is the possibility
that the market prices of the Portfolios' investments may decline due to an
increase in market interest rates. Generally, the longer the maturity of a
fixed-income security, the greater is the effect on its value when rates
increase.

Certain securities pay interest at variable or floating rates. Variable rate
securities reset at specified intervals, while floating rate securities reset
whenever there is a change in a specified index rate. In most cases, these reset
provisions reduce the effect of market interest rates on the value of the
security. However, some securities do not track the underlying index directly,
but reset based on formulas that can produce an effect similar to leveraging;
others may provide for interest payments that vary inversely with market rates.
The market prices of these securities may fluctuate significantly when interest
rates change.

CREDIT RISK

A Portfolio is also subject to credit risk, i.e., the risk that an issuer of
securities will be unable to pay principal and interest when due, or that the
value of the security will suffer because investors believe the issuer is less
able to pay. This is broadly gauged by the credit ratings of the securities in
which a Portfolio invests. However, ratings are only the opinions of the
agencies issuing them and are not absolute guarantees as to quality. Not all
securities are rated.

Moody's Investors Service considers debt securities rated Baa to have
speculative characteristics. Debt securities rated below investment grade (i.e.,
securities rated below Baa/BBB) are deemed by the rating agencies to be
speculative and may involve major risk of exposure to adverse conditions. These
ratings may indicate that the securities are highly speculative and may be in
default or in danger of default as to principal and interest. Unrated securities
of comparable quality share these risks.

Not all government securities are backed by the full faith and credit of the
United States. Some are backed only by the credit of the issuing agency or
instrumentality. Accordingly, there is a risk of default on these securities.

16
<PAGE>
CALL RISK

Many fixed income securities, especially those issued at high interest rates,
provide that the issuer may repay them early. Issuers often exercise this right
when interest rates are low. Accordingly, holders of callable securities may not
benefit fully from the increase in value that other fixed income securities
experience when rates decline. Furthermore, a Portfolio reinvests the proceeds
of the payoff at current yields, which are lower than those paid by the security
that was paid off.

SPECIAL RISKS OF HIGH YIELD SECURITIES

Securities rated below Baa/BBB, commonly known as junk bonds or high yield
securities, have speculative characteristics. Accordingly, there is a greater
possibility that the issuers of these securities may be unable to make timely
payments of interest and principal and thus default. If this happens, or is
perceived as likely to happen, the values of these investments will usually be
more volatile. These securities may be less liquid than higher-rated securities,
which means a Portfolio may have difficulty selling them at times, and may have
to apply a greater degree of judgment in establishing a price. When a Portfolio
buys lower rated debt, the achievement of its goals depends more on the
Advisers' ability than would be the case if a Portfolio were buying investment
grade debt. Unrated securities of comparable quality share these risks.

BORROWING RISK

When a Portfolio is borrowing money or otherwise leveraging its portfolio, the
value of an investment in that Portfolio will be more volatile and all other
risks will tend to be compounded. This is because leverage tends to exaggerate
the effect of any increase or decrease in the value of a Portfolio's holdings.
Portfolios may take on borrowing risk by using reverse repurchase agreements,
dollar rolls and other borrowings, by investing collateral from loans of
portfolio securities, through the use of when-issued, delayed-delivery or
forward commitment transactions or by using other derivatives. The use of
leverage may also cause a Portfolio to liquidate positions when it may not be
advantageous to do so to satisfy its obligations or meet segregation
requirements.

LIQUIDITY RISK

Liquidity risk exists when particular investments are difficult to sell. A
Portfolio may not be able to sell these illiquid investments at the best prices.
Investments in derivatives, foreign investments, restricted securities,
securities having small market capitalization, and securities having substantial
market and/or credit risk tend to involve greater liquidity risk.

SPECIAL RISKS OF MORTGAGE-BACKED AND ASSET-BACKED SECURITIES

Mortgage-backed securities represent an interest in a pool of mortgages. When
market interest rates decline, many mortgages are refinanced, and
mortgage-backed securities are paid off earlier than expected. Prepayments may
also occur on a scheduled basis or due to foreclosure. The effect on a
Portfolio's return is similar to that discussed above for call risk.

When market interest rates increase, the market values of mortgage-backed
securities decline. At the same time, however, mortgage refinancings and
prepayments slow, which lengthens the effective maturities of these securities.
As a result, the negative effect of the rate increase on the market value of
mortgage-backed securities is usually more pronounced than it is for other types
of fixed income securities, potentially increasing the volatility of a
Portfolio.

Asset-backed securities are structured like mortgage-backed securities, but
instead of mortgage loans or interests in mortgage loans, the underlying assets
may include such items as motor vehicle installment sales or installment loan
contracts, leases of various types of real and personal property, and
receivables from credit card agreements. The ability of an issuer of
asset-backed securities to enforce its security interest in the underlying
assets may be limited. Asset-backed securities are subject to many of the same
risks as mortgage-backed securities.

Prepayments may cause losses on securities purchased at a premium. At times,
some of the mortgage-backed and asset-backed securities in which a Portfolio may
invest will have higher than market interest rates and therefore will be
purchased at a premium above their par value. Unscheduled prepayments, which are
made at par, will cause a Portfolio to experience a loss equal to any
unamortized premium.

                                                                              17

YEAR 2000

Like other mutual funds (and most organizations around the world), the
Portfolios could be adversely affected by computer problems related to the year
2000. These could interfere with operations of the Portfolios, their Manager,
Distributor or Advisers, or other service providers or could impact companies in
which the Portfolios invest.

While no one knows if these problems will have any impact on the Portfolios or
on financial markets in general, the manager and its affiliates are taking steps
to protect fund investors. These include making modifications to their software
and systems and communicating with major service providers. No assurances can be
given that the Portfolios, their Manager,Distributor or Advisers will not be
adversely affected by computer problems related to the year 2000.

NON-DIVERSIFICATION

The Western Asset Non-U.S. Fixed Income Portfolio and the Western Asset Global
Strategic Income Portfolio are non-diversified, meaning each 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 could if it were a
"diversified" company under the Investment Company Act. When the Portfolios'
assets are invested in the securities of a limited number of issuers, or in a
limited number of countries or currencies, the value of its shares will be more
susceptible to any single economic, political or regulatory event than shares of
a more diversified fund.

DERIVATIVES RISK

A Portfolio may engage in a variety of transactions using "derivatives," such as
futures, options, warrants and swaps. Derivatives are financial instruments
whose value depends upon, or is derived from, the value of something else, such
as one or more underlying investments, indexes or currencies. Derivatives may be
traded on organized exchanges, or in individually negotiated transactions with
other parties (these are known as "over the counter"). A Portfolio may use
derivatives both for hedging and non-hedging purposes, including for purposes of
enhancing returns. Although the Advisers have the flexibility to make use of
derivatives, they may choose not to for a variety of reasons, even under very
volatile market conditions.

Derivatives involve special risks and costs and may result in losses to a
Portfolio. The successful use of derivatives requires sophisticated management,
and a Portfolio will depend on the Adviser's ability to analyze and manage
derivatives transactions. The prices of derivatives may move in unexpected ways,
especially in abnormal market conditions. Some derivatives are "leveraged" and
therefore may magnify or otherwise increase investment losses to a Portfolio. A
Portfolio's use of derivatives may also increase the amount of taxes payable by
shareholders.

Other risks arise from the potential inability to terminate or sell derivatives
positions. A liquid secondary market may not always exist for a Portfolio's
derivatives positions at any time. In fact, many over-the-counter instruments
will not be liquid. Over-the-counter instruments also involve the risk that the
other party will not meet its obligations to a Portfolio.

HEDGING RISK

The decision as to whether and to what extent a Portfolio will engage in hedging
transactions to hedge against such risks as credit risk, currency risk and
market risk will depend on a number of factors, including prevailing market
conditions, the composition of the Portfolio and the availability of suitable
transactions. Accordingly, there can be no assurance that a Portfolio will
engage in hedging transactions at any given time or from time to time or that
any such strategies will be successful. Hedging transactions involve costs and
may result in losses.

TURNOVER

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 turnovers." As a result of a Portfolio's
investment policies, under certain market conditions a Portfolio's 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.

18
<PAGE>
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.

RISKS ASSOCIATED WITH OTHER POLICIES THE PORTFOLIOS MAY PURSUE

In addition to the investment strategies described above, a Portfolio may also
make other types of investments, and therefore may be subject to other risks.
Some of these risks are described in each Portfolio's Statement of Additional
Information ("SAI"). The terms "debt" and "fixed income securities" are used in
this Prospectus interchangeably, and, where used, are not intended to be
limiting.

At times the Advisers may judge that market conditions make pursuing a
Portfolio's investment strategies inconsistent with the best interests of its
shareholders. The Advisers then may temporarily use alternative strategies that
are mainly designed to limit a Portfolio's losses. Although the Advisers have
the flexibility to use these strategies, they may choose not to for a variety of
reasons, even in very volatile market conditions. These strategies may cause a
Portfolio to miss out on investment opportunities, and may prevent a Portfolio
from achieving its goal. In addition, an Adviser may also keep a portion of a
Portfolio's assets in cash for temporary or defensive purposes, in order to meet
redemption requests, or for investment purposes.

Except for the investment objective of each of the Western Asset Core, Western
Asset Intermediate and Western Asset Money Market Portfolios, the Directors may
change a Portfolio's investment objective, investment strategies and other
policies without shareholder approval.

PERFORMANCE INFORMATION

The following information provides some indication of a Portfolio's risks. The
charts and tables show year-to-year changes in the performance of the
Institutional Class shares for the Western Asset Core and Western Asset
Intermediate Portfolios. The tables following the charts compare each
Portfolio's performance to that of a broad measure of market performance. SEC
Rules do not require charts and tables for the other Portfolios or for the
Financial Intermediary Class shares. However, the performance for the Financial
Intermediary Class would be lower for each Portfolio since this Class has higher
expenses. Of course, a Portfolio's past performance is not an indication of
future performance.

FEES AND EXPENSES

The following tables describe the fees and expenses that you may pay if you buy
and hold shares of a Portfolio.

Expenses are based on annualized actual expenses for the one year period (or
since inception, if shorter) ended March 31, 1999 for the Western Asset
Intermediate Portfolio, Western Asset Core Portfolio, Western Asset Core Plus
Portfolio, Western Asset Non-U.S. Fixed Income Portfolio and LM Value
Institutional Portfolio. Expenses for the other Portfolios are based on
estimated amounts for the current fiscal year.

The examples below the tables are intended to help you compare the cost of
investing in a Portfolio with the cost of investing in other mutual funds. The
examples assume that you invest $10,000 in a Portfolio for the time periods
indicated and then redeem all of your shares at the end of those periods. The
examples also assume that your investment has a 5% return each year and that the
Portfolio's operating expenses remain the same. Your actual costs may be higher
or lower. <TABLE> <CAPTION> WESTERN ASSET GOVERNMENT MONEY MARKET PORTFOLIO

     *The 12b-1 fees shown in the tables reflect the amount to which the
     Directors have currently limited payments under the Portfolios'
     Distribution Plans. Pursuant to each Portfolio's Distribution Plan, the
     Directors may increase the 12b-1 fees to 0.40% of average net assets
     without shareholder approval.

     **The Manager is contractually obligated to limit Portfolio expenses to the
     level shown through August 1, 2000.

     + Shareholders of the LMBalanced Institutional Portfolio ("Balanced
     Portfolio") will indirectly bear the Balanced Portfolio's pro rata share of
     the operating expenses incurred by the underlying Portfolios in which the
     Balanced Portfolio invests. Consequently, the fees and corresponding
     examples for the Balanced Portfolio include both the estimated fees of the
     Balanced Portfolio and a composite of the fees of the Core Portfolio and
     the Value Institutional Portfolio actually incurred in the last fiscal
     year. The Manager is contractually obligated to limit the expenses of the
     underlying Portfolios through August 1, 2000. For the purposes of
     calculating the effect of the fees of the underlying Portfolios on
     BalancedPortfolio shareholders, it has been assumed that LMFAwill allocate
     60% of the BalancedPortfolio's assets to the Value Institutional Portfolio
     and 40% to the Core Portfolio. LMFAreserves the right to vary the
     allocation of the Balanced Portfolio's assets as it deems appropriate,
     subject to certain limitations discussed earlier in this Prospectus. The
     actual fees and expenses incurred directly and indirectly by shareholders
     of the Balanced Portfolio may be higher or lower than those shown above.

                                                                              27

MANAGEMENT OF THE PORTFOLIOS

GENERAL

LMIFA I and LMIFA II are open-end management investment companies comprised of a
variety of separate investment portfolios. LMIFA I was incorporated in Maryland
on May 16, 1990. LMIFA II was incorporated in Maryland on January 13, 1998.

BOARD OF DIRECTORS

The business affairs of LMIFA I and LMIFAII are managed under the direction of a
Board of Directors for each corporation, and the Directors of each corporation
are responsible for generally overseeing the conduct of the relevant Portfolio's
business. Information about the Directors and executive officers may be found in
the relevant SAI.

Each 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 Manager a
monthly fee based on the average net assets of the Portfolio at the following
annual rates (shown prior to any waivers or reimbursements):

month the annual rate set forth in the Fees and Expenses section. Any amounts
waived or reimbursed in a particular fiscal year will be subject to repayment by

Neither Western Asset, WAGM nor Batterymarch employs individual portfolio
managers to determine the investments of a Portfolio. Instead, the day-to-day
management of the various Portfolios' investments will be the responsibility of
the Western Asset Investment Strategy Group, the WAGM Investment Strategy Group,
the Batterymarch Developed Markets (U.S.)team, the Batterymarch Developed
Markets (EAFE) team or the Batterymarch Emerging Markets team, as the case may
be.

DISTRIBUTORS

Legg Mason Wood Walker, Incorporated ("LMWW") is the distributor of each
Portfolio's shares. LMWW 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 shares of the LMIFA I Portfolios 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. The
Portfolios may use LMWW, among others, as broker for agency transactions in
listed and over-the-counter securities at commission rates and under
circumstances consistent with the policy of best execution.

Some securities considered by an Adviser for purchase by a Portfolio may also be
appropriate for other clients served by the Adviser. To the extent the Portfolio
and such other clients purchase the same security, transactions in such security
will be allocated among the Portfolio and such other clients in a manner
considered fair and reasonable by the Adviser.

EXPENSES

Each Portfolio pays its share of all expenses that are not assumed by the
Manager, the 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).

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 LMInstitutional Advisors, Inc. at the following
address: P.O. Box 17635, Baltimore, Maryland 21297-1635. The Portfolios have
established minimum investment criteria that vary depending upon which class of
shares you wish to purchase. For Institutional Class shares, investors must have
at least $50 million in investable assets and invest in the aggregate at least
$1 million in the Portfolios. For Financial Intermediary Class shares, investors
must have at least $30 million in investable assets and invest in the aggregate
at least $1 million in the Portfolios. The Portfolios reserve the right to
revise the minimum investment requirement and may waive it at their sole
discretion.

<PAGE>
A purchase order, together with payment in one of the forms described in the
following paragraphs, received by Boston Financial Data Services (the "Transfer
Agent"or "BFDS") prior to the close of regular trading on the New York Stock
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 be made by
federal funds wire. Before wiring federal funds, the investor must first
telephone the Portfolio at 1-888-425-6432 to receive instructions for wire
transfer. On the telephone, the following 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
DDA#99046096
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 its portfolio securities for purposes of determining net asset
value. (See "Net Asset Value" below.) Investors who wish to purchase Portfolio
shares through the contribution of securities should contact the Portfolio at
1-888-425-6432 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' assets pursuant to the class' 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.

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.

                                                                              31
<PAGE>
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 LMWW 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 it determines that 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 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
Portfolio. Signature guarantees may be required. See "Signature Guarantee"
below. All correspondence must include the account number and must be sent to:

                         LM Institutional Advisors, Inc.
                                 P.O. Box 17635
                         Baltimore, Maryland 21297-1635

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, LMWW, financial intermediaries and other parties that provide services in
connection with or are otherwise involved in the distribution of shares or
administration of plans or programs that use Portfolio shares as their funding
medium, and to reimburse certain other expenses and payments. Payments under the
Plans are currently limited to 0.25% (or 0.10% in the case of the Western Asset
Government Money Market Portfolio and the Western Asset Money Market Portfolio)
of average daily net assets. For more information regarding the Plans and their
terms, see the relevant SAI.

REDEMPTION OF SHARES

Portfolio shares may be redeemed through three methods: (1) by sending a written
request for redemption to LM Institutional Advisors, Inc. at P.O. Box 17635,
Baltimore, Maryland 21297-1635; (2) by calling the Portfolio at 1-888-425-6432;
or (3) by wire communication with the Transfer Agent. In each case, the investor
should first notify the Portfolio at 1-888-425-6432 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, 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 for redemption as described below (a request "in good
order") 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.
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. The Portfolios may
refuse to effect redemption requests during periods permitted by 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 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 one business day
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.

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 by calling 1-888-425-6432.

Any Portfolio may elect to close any shareholder account when the current value
of the account is less than $1 million due to redemptions or exchanges by the
shareholder 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.
                                                                              33

SIGNATURE GUARANTEE

When a signature guarantee is called for, the shareholder should have "Signature
Guaranteed" stamped under his or her 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, provided that the shares of that class are
being offered at the time of the proposed exchange. Investments by exchange
among any of the Portfolios 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 without notice to the extent permitted by applicable law,
limit the amount or number of exchanges or reject any exchange. For further
information concerning the exchange privilege, or to make an exchange, please
contact the Portfolio at 1-888-425-6432.

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

34
<PAGE>
securities will be valued at fair value as determined in good faith by the
Directors or persons acting at their direction. In addition, if a Portfolio
holds securities that are primarily listed on foreign exchanges that trade on
days when the Exchange is not open, the net asset value of the Portfolio's
shares may be subject to change on days when shareholders will not be able to
purchase or redeem the Portfolio's shares.

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 LMIFA I Portfolios (other than the Western Asset Money Market and Western
Asset Government Money Market Portfolios), the LM Value Institutional Portfolio
and the LM Total Return Institutional Portfolio declare and pay dividends
quarterly out of their net investment income, if available, for that quarter.
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. All other
Portfolios declare and pay dividends annually out of their net investment
income, if available, for that year. 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 monthly
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 additional shares may be made by notifying the Portfolio in
writing.

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 or continue 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

                                                                              35
<PAGE>
from the Portfolio's investment income and net short-term gains. Portfolio
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) will be taxable as long-term capital gain
(generally at a 20% rate for noncorporate shareholders).

Distributions of income and capital gains are taxable whether received in cash
or reinvested in additional shares. If a dividend or distribution is made
shortly after a shareholder purchases shares in a Portfolio, while in effect a
return of capital to the Shareholder, the dividend or distribution is taxable as
described above.

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.

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 Internal Revenue Code of 1986 (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. A Portfolio may make an election to mark the gains (and to a limited
extent losses) in such investments "to the market" as though it had sold and
repurchased its holdings in those passive foreign investment companies on the
last day of the Portfolio's taxable year.

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

In addition to income tax on a Portfolio's distributions, any gain that results
if a shareholder (other than an IRA or other tax-exempt investor) sells or
exchanges its shares generally is subject to income tax. The LM Balanced
Institutional Portfolio's use of a "fund of funds" structure could adversely
affect the character, timing and amount of distributions to shareholders.

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).

FINANCIAL HIGHLIGHTS

The financial highlights tables are intended to help you understand each
Portfolio's recent financial performance for the past five years or, if shorter,
since the inception of the Portfolio's operations. Certain information reflects
financial results for a single Portfolio share. The total returns represent the
rate that an investor would have earned or lost on an investment in the
Portfolios, assuming reinvestment of all dividends and distributions. This
information has been derived from the financial statements of LMIFA I and LMIFA
II, which have been audited by PricewaterhouseCoopers LLP and Ernst & Young LLP,
respectively. Their reports and the Portfolios' financial statements are
included in the Portfolios' annual reports to shareholders, which are available
upon request.

   APPENDIX A: PRIOR PERFORMANCE OF LMIFA II ADVISERS' OTHER ACCOUNTS


The LM Value Institutional Portfolio has performance results only for the period
from September 22, 1998 to September 30, 1999. The other seven Portfolios of
LMIFA II have not yet commenced operations and have no performance record of
their own. However, other than in the case of the LM Balanced Institutional
Portfolio, the Advisers of LMIFA II have managed other client accounts that have
investment objectives, policies and strategies that are similar, but not
necessarily identical, to those of the Portfolios that they manage. In the case
of the LM Balanced Institutional Portfolio, each of the Portfolios in which that
Portfolio invests has prior performance. Representative investment performance
for these accounts is stated below. The investment performance is shown on an
annual total return basis, with returns for periods of less than one year not
annualized, and on an average annual total return basis. The performance
information is provided through September 30, 1999.

The prior performance information shown is in two categories and reflects the
performance of either: (1) composites of certain of the Adviser's separately
managed accounts and (2) SEC-registered, open-end investment companies. In each
case, the account or accounts have investment objectives, policies and
strategies substantially similar (although not necessarily identical) to those
of the relevant Portfolio and were managed throughout the periods shown using
investment styles and strategies substantially similar (although not necessarily
identical) to those of the relevant Portfolio, except in the case of the LM
Balanced Institutional Portfolio, where information is provided for each of the
equity and fixed income components. To the extent a composite of accounts is
shown, the composite includes all of the fully-discretionary, fee-paying
accounts managed by such Adviser during the periods shown using investment
objectives, policies and strategies substantially similar (although not
necessarily identical) to those of the relevant Portfolio.

The performance information for composites has been adjusted to give effect to
the Portfolios' estimated fees and expenses, before waivers and reimbursements,
for the Financial Intermediary Class shares as shown in the tables beginning on
page 21. The performance information for composites assumes reinvestment of all
dividends and proceeds from capital transactions and has been prepared in
accordance with the Performance Presentation Standards established by the
Association for Investment Management and Research ("AIMR standards"), except
for the deduction of estimated fees and expenses listed in the Fees and Expenses
tables as noted above. The performance results would be more favorable if they
had been adjusted for estimated fees and expenses of the Institutional Class
shares of the Portfolios. Accounts included in composites are generally not
subject to the diversification requirements, specific tax restrictions and
investment limitations imposed on each of the Portfolios by the Investment
Company Act of 1940 (the "1940 Act") or the Code. The performance results for
these accounts might have been adversely affected had the accounts been subject
to these requirements, restrictions and limitations.

Performance for SEC-registered, open-end investment companies is calculated
using the SEC's standardized total return formula, which is based upon the
change in value of an assumed initial investment of $10,000 from the beginning
through the end of a period and assumes reinvestment of all dividends and other
distributions. For periods of more than one year, the result is then annualized
and expressed as a percentage of the initial investment, and includes the effect
of operating expenses, including advisory fees. Information about the investment
objectives, policies, expenses and net assets of each of the investment
companies follows the performance information.

The method for calculating performance for the composites produces a different
result than if the performance were calculated using the SEC's method for
calculating the total return of an open-end investment company.

A Portfolio's expenses, timing of purchases and sales of portfolio securities,
timing and availability of cash flows, cash positions (which are typically
greater for open-end investment companies than for separate accounts), and
brokerage commissions are some of the factors that might cause performance
results of the Portfolio to vary from that of the composites and/or investment
companies shown. In particular, the large infusions of cash that are typically
associated with the commencement of operations of new mutual funds such as the
Portfolios, as well as differences in the amount of assets held by the
Portfolios as opposed to the accounts and/or investment companies shown below,
can affect the ability and the manner in which security positions are
accumulated or liquidated, and thus may cause a Portfolio's performance to vary
from that of the composites and/or investment companies shown below.

As noted above, the investment objectives, policies, styles and strategies of
each Portfolio are not necessarily identical to those of the relevant composites
and/or investment companies shown below. Again, for these and other reasons, the
performance of the Portfolios will vary from that of the composites and/or
investment companies.

Prior Performance of Accounts Similar to the LM Value Institutional Portfolio.

The investment performance for the period from October 1, 1989 to September 30,
1999 of all accounts managed by LMFA and Legg Mason Capital Management, Inc.
("LMCM"), an affiliate of LMFA that shares investment personnel with LMFA, that
have investment objectives, policies and strategies that are substantially
similar to those of the Portfolio is shown below. The benchmark index to which
the accounts are compared is the S&P 500 Index. The S&P 500 Index is an
unmanaged index representing the performance of 500 companies selected by S&P.
Although used as a benchmark, the Index's performance may not be comparable to
the accounts' performance because, unlike the performance of the accounts, the
Index's performance has not been adjusted for any fees or expenses.

The number of accounts included in the composite has ranged from 1 to 12 over
the relevant period and the aggregate assets of the accounts has ranged from
$637 million to $12.4 billion over the period. One of the accounts included in
the composite is a registered investment company. In addition, all of the fully
discretionary accounts of LMCM with assets greater than $25 million are included
in the composite after a period of three months and after the account becomes
fully invested. Accounts included in the composite are generally not subject to
the diversification requirements, specific tax restrictions and investment
limitations imposed on the Portfolio by the 1940 Act or the Code. The
performance results for these accounts might have been adversely affected had
the accounts been subject to these requirements, restrictions and limitations.
These potential differences do not adversely affect the determination that the
accounts included in this composite are managed in a substantially similar
manner to the Portfolio.

Value Trust, which commenced operations on April 16, 1982, is a diversified
open-end investment company. Value Trust's investment objective is long-term
growth of capital. Value Trust invests primarily in equity securities that, in
the Adviser's opinion, offer the potential for capital growth. The Adviser
follows a value discipline in selecting securities, and therefore seeks to
purchase securities at large discounts to the Adviser's assessment of their
intrinsic value. Intrinsic value, according to the Adviser, is the value of the
company measured, to different extents depending on the type of company, on
factors such as, but not limited to, the discounted value of its projected
future free cash flows, the company's ability to earn returns on capital in
excess of its cost of capital, private market values of similar companies, the
value of its assets, and the costs to replicate the business. Qualitative
factors, such as an assessment of the company's products, competitive
positioning, strategy, industry economics and dynamics, regulatory frameworks
and more, are also important. Securities may be undervalued due to uncertainty
arising from the availability of accurate information, economic growth and
change, changes in competitive conditions, technological change, changes in
government policy or geo-political dynamics, and more. The Adviser takes a
long-term approach to investing, generally characterized by long holding periods
and low portfolio turnover. Value Trust generally invests in companies with
market capitalizations greater than $5 billion, but may invest in companies of
any size.

Value Trust may also invest in debt securities of companies having one or more
of the above characteristics. Value Trust may invest up to 25% of its net assets
in long-term debt securities. Up to 10% of its total assets may be invested in
debt securities rated below investment grade.

For temporary purposes, or when cash is temporarily available, Value Trust may
invest without limit in investment grade, short-term debt instruments, including
government, corporate and money market securities.

Special Investment Trust, which commenced operations on December 30, 1985, is a
diversified open-end investment company. Special Investment Trust's investment
objective is capital appreciation. Special Investment Trust invests primarily in
equity securities, and securities convertible into equity securities, of
companies whose market capitalizations are typically classified as small to
mid-sized. The Adviser defines small to mid-sized companies as those below the
top 500 U.S. companies in terms of market capitalization. It also invests in
"special situations" without regard to market capitalization. Special situations
are securities undergoing unusual or possibly one-time developments that, in the
opinion of the Adviser, make them attractive for investment. Such developments
may include actual or anticipated: sale or termination of an unprofitable part
of the company's business; change in the company's management or in management's
philosophy; a basic change in the industry in which the company operates;
introduction of new products or technologies; or the prospect or effect of
acquisition or merger activities.

Special Investment Trust's Adviser follows a value discipline in selecting
securities, and therefore seeks to purchase securities at large discounts to the
Adviser's assessment of their intrinsic value. Intrinsic value, according to the
Adviser, is the value of the company measured, to different extents depending on
the type of company, on factors such as, but not limited to, the discounted
value of its projected future free cash flows, the company's ability to earn
returns on capital in excess of its cost of capital, private market values of
similar companies, the value of its assets, and the costs to replicate the
business. Qualitative factors, such as an assessment of the company's products,
competitive positioning, strategy, industry economics and dynamics, regulatory
frameworks and more, are also important. Securities may be undervalued due to
uncertainty arising from the availability of accurate information, economic
growth and change, changes in competitive conditions, technological change,
changes in government policy or geo-political dynamics, and more.

Special Investment Trust also invests in debt securities of companies having one
or more of the above characteristics. Special Investment Trust may invest up to
35% of its net assets in debt securities rated below investment grade. Special
Investment Trust may invest up to 20% of its total assets in securities of
companies involved in actual or anticipated reorganizations or restructurings.

For temporary defensive purposes, or when cash is temporarily available, Special
Investment Trust may invest without limit in investment grade, short-term debt
instruments, including government, corporate and money market securities.

As of September 30, 1999, Special Investment Trust had approximately $2.1
billion in assets. For its fiscal year ended March 31, 1999, the Primary Class
shares of Special Investment Trust had a total expense ratio of 1.84%.

appreciation and/or future income. The Adviser follows a value discipline in
selecting securities, and therefore seeks to purchase securities at large
discounts to the Adviser's assessment of their intrinsic value. Intrinsic value,
according to the Adviser, is the value of the company measured, to different
extents depending on the type of company, on factors such as, but not limited
to, the discounted value of its projected future free cash flows, the company's
ability to earn returns on capital in excess of its cost of capital, private
market values of similar companies, the value of its assets, and the costs to
replicate the business. Qualitative factors, such as an assessment of the
company's products, competitive positioning, strategy, industry economics and
dynamics, regulatory frameworks and more, are also important. Securities may be
undervalued due to uncertainty arising from the availability of accurate
information, economic growth and change, changes in competitive conditions,
technological change, changes in government policy or geo-political dynamics,
and more. The Total Return Trust may invest in companies of any size.

Total Return Trust may invest in money market securities for temporary defensive
purposes or when cash is temporarily available. Consistent with the investment
objective, Total Return Trust may also invest in debt securities when the
Adviser believes the return on certain debt securities may equal or exceed the
return on equity securities. Total Return Trust may invest in debt securities of
any maturity of both foreign and domestic issuers without regard to rating, and
may invest its assets in such securities without regard to a percentage limit.
The Adviser currently anticipates that under normal market conditions, the fund
will invest no more than 50% of its total assets in intermediate-term and
long-term debt securities and no more than 5% of its total assets in debt
securities not rated investment grade.

As of September 30, 1999, Total Return Trust had approximately $544.5 million in
assets. For its fiscal year ended March 31, 1999, the Primary Class shares of
Total Return Trust had a total expense ratio of 1.87%.

International Equity Trust, which commenced operations on February 17, 1995, is
a diversified open-end investment company. International Equity Trust's
investment objective is maximum long-term total return. International Equity
Trust's Adviser currently intends to invest substantially all of the fund's
assets in non-U.S. equity securities. The primary focus of the Adviser is stock
selection, with a secondary focus on country allocation. The Adviser uses a
bottom-up, quantitative stock selection process

                                                                              52
<PAGE>

for the developed markets portion of the fund's portfolio. The cornerstone of
this process is a proprietary stock selection model that ranks the 2,800 stocks
in the fund's principal investable universe by relative attractiveness on a
daily basis. The quantitative factors within this model are intended to measure
growth, value, fundamental expectations and technical indicators (i.e., supply
and demand). Because the same quantitative factors are not effective across all
markets due to individual market characteristics, the adviser adjusts the stock
selection model to include factors that its research indicates are effective,
eliminating factors that are not valid in a particular market. The Adviser runs
the stock selection model and re-balances the portfolio daily, purchasing all
stocks ranked "buys" by the model and selling all stocks ranked "sells." Stocks
are sold when the original reason for purchase no longer pertains, the
fundamentals have deteriorated or portfolio re-balancing warrants.

Country allocation for the developed markets portion of the fund is based on
rankings generated by the Adviser's proprietary country model. The Adviser
examines securities from over 20 international stock markets, with emphasis on
several of the largest: Japan, United Kingdom, France, Canada and Germany.
International Equity Trust may invest up to 35% of its total assets in emerging
market securities. The Adviser's investment strategy for the emerging markets
portion of the fund represents a distinctive combination of tested quantitative
methodology and traditional fundamental analysis. The emerging markets
allocation focuses on higher-quality, dominant companies which the adviser
believes to have strong growth prospects and reasonable valuations. Country
allocation for the emerging markets portion of the portfolio also combines
quantitative and fundamental approaches.

International Equity Trust's investment portfolio will normally be diversified
across a broad range of industries and across a number of countries, consistent
with the objective of maximum total return. The adviser may also seek to enhance
portfolio returns through active currency hedging strategies. More than 25% of
International Equity Trust's total assets may be denominated in a single
currency or invested in securities of issuers located in a single country.

When cash is temporarily available, or for temporary defensive purposes, when
the adviser believes such action is warranted by abnormal market or economic
situations, International Equity Trust may invest without limit in cash and U.S.
dollar-denominated money market instruments, including repurchase agreements of
domestic issuers. Such securities will be rated investment grade or, if unrated,
will be determined by the fund's adviser to be investment grade.

As of September 30, 1999, International Equity Trust had approximately $254.7
million in assets. For its fiscal year ended December 31, 1998, the Primary
Class shares of International Equity Trust had a total expense ratio of 2.14%.

Prior Performance of Accounts Similar to the Batterymarch Emerging Markets
Portfolio.

The investment performance for the period from January 1, 1994 to September 30,
1999 of all accounts managed by Batterymarch that have investment objectives,
policies and strategies that are substantially similar to those of the Portfolio
is shown below. January 1, 1994 represents the commencement of investment
activities for the initial account included in the composite. The benchmark
index to which the accounts are compared is the MSCI Emerging Markets Free Index
with Gross Dividends ("MSCI EMF"). The MSCI EMF is an unmanaged index
representing the performance of a market weighted aggregate of 26 individual
emerging country indexes and takes into account local and market restrictions on
share ownership

comparable to the accounts' performance since, unlike the performance of the
accounts, the Index's performance has not been adjusted for any fees or
expenses.

The number of accounts included in the composite has ranged from 1 to 4 over the
relevant period and the aggregate assets of the accounts has ranged from $43
million to $1 billion over the period. One of the accounts included in the
composite is a registered investment company. Accounts included in the composite
are generally not subject to the diversification requirements, specific tax
restrictions and investment limitations imposed on the Portfolio by the 1940 Act
or the Code. The performance results for these accounts might have been
adversely affected had the accounts been subject to these requirements,
restrictions and limitations. These potential differences do not adversely
affect the determination that the accounts included in this composite are
managed in a substantially similar manner to the Portfolio.

Emerging Markets Trust, which commenced operations on May 28, 1996, is a
diversified open-end investment company. Emerging Markets Trust's investment
objective is long-term capital appreciation. Emerging Markets Trust's Adviser
intends to invest substantially all of the fund's assets in equity securities
and convertible securities of emerging market issuers.

Emerging Markets Trust intends to invest in Asia, Latin America, the Indian
Subcontinent, Southern and Eastern Europe, the Middle East and Africa, although
it may not invest in all these markets at all times and may not invest in any
particular market when it deems investment in that country or region to be
inadvisable.

More than 25% of Emerging Markets Trust's total assets may be denominated in a
single currency or invested in securities of issuers located in a single
country.

The Adviser focuses on higher-quality, dominant emerging markets companies which
the Adviser believes to have strong growth prospects and reasonable valuations,
selected from a principal investable universe of approximately 1,000 stocks. The
Adviser's emerging markets investment strategy represents a distinctive
combination of quantitative methodology and traditional fundamental analysis.
Traditional "on-the-ground" fundamental research is combined by the Adviser with
tested quantitative valuation disciplines in those markets where reliable data
is available. In determining country allocation, the Adviser also merges
quantitative and fundamental approaches. In markets with reliable historical
data, buy and sell decisions are driven by a combination of quantitative
valuations and the Adviser's fundamental opinions. Stocks are sold when the
original reason for purchase no longer pertains, the fundamentals have
deteriorated or portfolio re-balancing warrants.

When cash is temporarily available, or for temporary defensive purposes, when
the Adviser believes such action is warranted by abnormal market or economic
situations, the fund may invest without limit in cash and U.S.
dollar-denominated money market instruments, including repurchase agreements of
domestic issuers. Such securities will be rated investment grade or, if unrated,
will be determined by the adviser to be investment grade.

As of September 30, 1999, Emerging Markets Trust had approximately $77.5 million
in assets. For its fiscal year ended December 31, 1998, the Primary Class shares
of Emerging Markets Trust had a total expense ratio of 2.50% (after fee waivers;
2.78% in the absence of such waivers).
