 Indexing

The Funds in this Prospectus share the same basic investment strategy. They are
designed to track the performance of a stock or bond market index.

This strategy distinguishes an index fund from an "actively managed" mutual
fund. Instead of choosing investments based on judgment, a portfolio manager
looks to an index to determine which securities the Fund should own. Instead of
trying to outperform the market or segment it tracks, each Fund tries to pro-
vide investment results that match, as closely as possible, the performance of
its Index. And if the securities contained in a Fund's Index are losing value
or are downgraded by investment analysts, the Fund will continue to purchase
and hold those securities, even if the Fund loses money as a result.

The Funds may use replication or sampling techniques to track the performance
of their Indexes. Replication involves a Fund holding each security in its
Index in the same proportion as the security appears in the Index. Sampling
techniques involve investing in a smaller number of securities included in the
Index that are selected to resemble the Index in terms of industry weightings,
market capitalization, price/earnings ratio, dividend yield or other character-
istics. A Fund may also purchase and sell securities in anticipation of addi-
tions or deletions to its Index.

Each of the Funds attempts to achieve, in rising and falling markets, a corre-
lation of at least 95% between the total return of its net assets before fees
and expenses and its respective Index. Of course, like most index funds, there
is no guarantee that a Fund will be able to achieve or maintain this level of
correlation. And, like other mutual funds, a Fund will have operating expenses
that affect the Fund's ability to track its Index.

The Funds may use derivatives to track the performance of their Indexes. Deriv-
atives are financial instruments whose values are derived, at least in part,
from the prices of other securities or specified assets, indexes or rates. The
Funds might use derivatives to simulate full investment in the Fund's Index
while maintaining sufficient liquidity to satisfy redemptions and operating
expenses, to facilitate trading in the securities of companies that comprise
the Index, to reduce transaction costs or to seek higher investment returns
when a contract is priced more attractively than the securities comprising the
Fund's Index.

Because the composition of an Index tends to be comparatively stable, index
funds historically have experienced lower portfolio turnover than actively man-
aged funds.

Smith Barney S&P 500 Index Shares

The Fund's goal is to provide investment results that, before fees and
expenses, correspond to the price and yield performance of the Standard &
Poor's 500(R) Composite Stock Price Index (S&P 500 Index).

The Index

The S&P 500 Index is one of the most widely used benchmarks of U.S. equity per-
formance. The S&P 500 Index consists of 500 stocks chosen for market capital-
ization, liquidity and industry group representation. The S&P 500 Index is
market-value-weighted, so the larger of the 500 companies generally have a big-
ger impact on the performance of the Index. The S&P 500 Index does not show
actual investment returns or reflect payment of management or brokerage fees,
which would lower the S&P 500 Index's performance. The S&P 500 Index is unman-
aged and does not have to maintain liquidity to meet redemption requests or pay
expenses.

Principal Strategies

Key investments The S&P 500 Index Fund will hold a broadly diversified portfo-
lio of common stocks that is comparable to the S&P 500 Index in terms of eco-
nomic sector weightings, market capitalization and liquidity. The Fund invests
at least 80% of its assets in common stocks included in the Index. The Fund
holds stocks of substantially all of the companies which comprise the S&P 500
Index. The Fund also may enter into repurchase agreements, lend portfolio secu-
rities and use certain types of derivative instruments to help implement its
goal.

Selection process The S&P 500 Index Fund is managed as a "pure" index Fund.
This means that the manager does not evaluate individual companies to identify
attractive investment candidates. Instead, the manager attempts to mirror the
investment performance of the Index as closely as possible by adjusting the
Fund's portfolio daily to reflect the companies included in the Index and their
weightings. Like most index funds, the Fund does not mirror the Index exactly
because, unlike the Index, the Fund must maintain a portion of its assets in
cash and liquid short-term securities to meet redemption requests and pay the
Fund's expenses. The Fund's returns are likely to be below those of the Index
because of the Fund's short-term investments and its operating expenses.

Who may want to invest

The S&P 500 Index Fund may be an appropriate investment if you:

 . Are seeking to participate in the long-term growth potential of U.S. large
  capitalization stocks

                                                       Smith Barney Mutual Funds

                                                                              3
<PAGE>


 . Are seeking an investment which tracks the performance of the S&P 500 Index

 . Are looking for an investment with potentially greater return but higher risk
  than a fund investing primarily in fixed income securities

 . Are willing to accept the risks of the stock market

Principal Risks

As with any mutual fund, you may lose money if you invest in the Fund. The
Fund's principal risks are:

Index Investing Risk Because the Fund is managed as an index fund, it will not
ordinarily sell a portfolio security because of the security's poor perfor-
mance. The Fund normally buys or sells a portfolio security only to reflect
additions or deletions of stocks that comprise its Index or to adjust their
relative weightings. Although the manager for the Fund seeks to replicate the
performance of the Index, the Fund may underperform its Index even before
deducting fees and expenses because the Fund must maintain a portion of its
assets in liquid short-term debt securities which historically have generated
significantly lower returns than common stocks. In addition, expenses and
transaction costs, the size of the Fund and the size and frequency of cash
flows into and out of the Fund, and the differences between how and when the
Fund and its Index are valued can also cause differences in performance.

Market Risk The Fund is exposed to the risks of investing in common stocks. The
Fund may not perform as well as other investments, if, among other things: the
Index declines or performs poorly relative to other related indexes or individ-
ual securities; an adverse event, such as an unfavorable earnings report, nega-
tively affects the price of an issuer in the Index; or the securities issued by
companies which comprise the Index fall out of favor with investors.

Derivatives Derivatives may be more sensitive than direct securities to changes
in interest rates or sudden market moves. Some derivatives also may be suscep-
tible to fluctuations in yield or value because of their structure or contract
terms. Even a small investment in derivative contracts can have a big impact on
the Fund's stock market exposure. Therefore, using derivatives can dispropor-
tionately increase losses and reduce opportunities for gains when stock prices
are changing. The Fund may not fully benefit from or may lose money on deriva-
tives if changes in their value do not correspond accurately to changes in the
value of the Fund's holdings. This may adversely affect the Fund's ability to
track its Index.

Certain derivative contracts present the risk that the other party to the con-
tract may not perform. Derivatives can also make the Fund less liquid and
harder to value, especially in declining markets.

More on the Fund's Investments and Risks

Money Market Instruments

The Fund may temporarily invest in money market instruments. The Fund invests
in money market instruments pending investment of proceeds of the sale of
shares of the Fund or settlement of purchases of securities by the Fund or to
maintain liquidity to meet anticipated redemptions. The Fund's investments in
money market instruments will likely cause the Fund's returns to differ from
those of the Index.

Foreign Investments

The Fund may purchase common stocks and ADRs of the foreign companies included
in the S&P 500 Index. These securities are publicly traded on U.S. securities
exchanges or over-the-counter markets. ADRs are U.S. dollar-denominated securi-
ties which represent an interest in an underlying foreign security. These com-
mon stocks and ADRs are subject to most of the special risks associated with
foreign investing, including currency, political, legal, regulatory and opera-
tional risks.

Securities Lending

If the Fund lends its securities to earn income, it will receive cash or other
securities as collateral for the loan, which must be returned to the borrower
at the completion of the loan. The Fund typically invests cash collateral
received in short-term investments. The Fund could lose money if the lent secu-
rities are not returned by the borrower at the termination of the loan, or if
the value of its short-term investment of the cash collateral declines over the
period of the loan.

                     Expenses on a $10,000 investment

This example is intended to help you compare the cost of investing in the Fund
to the cost of investing in other mutual funds. The example assumes that:

 .you invest $10,000 in the Fund for the time periods indicated;

 .you reinvest all dividends;

 .you then sell all of your shares at the end of those periods;

 .your investment has a 5% return each year--the assumption of a 5% return is
  required by the SEC for the purpose of this example and is not a prediction
  of the Fund's future performance; and

 .the Fund's operating expenses as shown in the table remain the same--the exam-
  ple reflects the cap on operating expenses.

More About the Index

The bar chart below sets forth the annual total returns of the S&P 500 Index
for each of the past ten calendar years. The line graph below shows the growth
of a $10,000 investment in the stocks comprising the Index over the past ten
calendar years. The data is provided to illustrate the past performance of the
Fund's Index and does not represent the performance of the Fund. Investors
should not consider this performance data as an indication of future perfor-
mance of the Fund. The returns are not intended to predict or suggest the
returns that might be experienced by the Fund or an individual investing in the
Fund.

All returns presented were calculated on a total return basis, which includes
the reinvestment of all distributions. Performance of the Fund for the periods
shown below would have been lower because of the Fund's short-term investments
and its operating expenses.

Smith Barney U.S. 5000 Index Shares

The Fund's goal is to provide long-term capital growth by approximating, before
fees and expenses, the performance of the Wilshire 5000 Total Stock Market
Index (Wilshire 5000 Index).

The Fund invests all of its assets in a separate mutual fund, called a Master
Portfolio, that has a substantially identical investment objective. For
simplicity's sake, all discussions of investment objectives, strategies and
risks of the Fund refers also to the objectives, strategies and risks of its
corresponding Master Portfolio, unless otherwise indicated.

The Index

The Wilshire 5000 Index, an unmanaged capitalization-weighted index of over
7,000 U.S. equity securities, consists of all the U.S. stocks regularly traded
on the New York and American Stock Exchanges and The Nasdaq Stock Market for
which daily pricing is available. The Wilshire 5000 Index does not show actual
investment returns or reflect payment of management or brokerage fees, which
would lower the Wilshire 5000 Index's performance. The Wilshire 5000 Index does
not have to maintain liquidity to meet redemption requests or pay expenses.

The Wilshire 5000 Index is comprised of the U.S. stocks in the S&P 500 Index,
and the stocks in the Wilshire 4500 Index.

Principal Strategies

Key investments The U.S. 5000 Index Fund invests in a sampling of securities
that are selected and weighted to result in investment characteristics compara-
ble to, and performance that will correlate with the performance before fees
and expenses of, the Wilshire 5000 Index. The statistical sampling techniques
are based on capitalization, industry exposures, dividend yield, price/earnings
ratio, price/book ratio and earnings growth. Under normal market conditions,
the Fund invests at least 90% of its assets in common stocks included in the
Wilshire 5000 Index.

Selection process The U.S. 5000 Index Fund follows an indexed or "passively
managed" approach to investing. This means that the Fund's manager determines
how the Fund's assets will be invested to match, to the extent feasible, the
capitalization range and returns of the Index and determines which securities
are to be purchased or sold to match or sample the Index. Also, the Fund's man-
ager does not evaluate individual companies to identify attractive investment
candidates. Instead, the manager attempts to mirror the performance of the
Index as closely as possible by adjusting the Fund's investments periodically
to reflect a sampling of the companies included in the Wilshire 5000 Index and
their weightings. Like most index funds, the Fund does not mirror the Index
exactly because, unlike the Index, the Fund must maintain a portion of its
assets in cash and liquid

short-term securities to meet redemption requests and pay the Fund's expenses.
The Fund's returns are likely to be below those of the Index because of the
Fund's short-term investments and its operating expenses.

Investment Structure The U.S. 5000 Index Fund is structured as a feeder fund.
The Fund does not buy individual securities directly. Instead, it invests all
of its assets in a corresponding Master Portfolio, the US Equity Index Master
Portfolio. The Master Portfolio invests in securities in accordance with
investment goals, policies and limitations that are similar to those of the
Fund.

The US Equity Index Master Portfolio seeks to achieve its objective by invest-
ing substantially all of its assets in two other Master Portfolios--the
Extended Index Master Portfolio (which invests substantially all of its assets
in a representative sample of stocks comprising the Wilshire 4500 Index) and
the S&P 500 Index Master Portfolio (which invests substantially all of its
assets in stocks comprising the S&P 500 Index). The US Equity Index Portfolio's
assets will be invested in the Extended Index Master Portfolio and the S&P 500
Index Master Portfolio in proportions adjusted periodically to approximate the
capitalization range of the Wilshire 5000 Index.


As other investors invest their assets in the Master Portfolio, certain eco-
nomic efficiencies may be realized with respect to the Master Portfolio. For
example, fixed expenses that otherwise would have been borne solely by the Fund
(and the other existing interestholders in the Master Portfolio) would be
spread across a larger asset base as more funds invest in the Master Portfolio.
However, if a mutual fund or other investor withdraws its investment from the
Master Portfolio, the economic efficiencies that should be available through
investment in the Master Portfolio may not be fully achieved or maintained. In
addition, given the relatively complex nature of the master/feeder structure,
accounting and operational difficulties could occur. For example, coordination
of calculation of net asset value could be affected at the master and/or feeder
level.

The U.S. 5000 Index Fund may withdraw its investment in its Master Portfolio,
without a shareholder vote, if the Board of Trustees determines that it is in
the best interests of the Fund and its shareholders to do so. Upon any such
withdrawal, the Board would consider what action might be taken, including the
investment of all the assets of the Fund in another pooled investment entity
having the same investment objective as the Fund or the hiring of a subadviser
to manage the Fund's assets.

Who may want to invest

The U.S. 5000 Index Fund may be an appropriate investment if you:

 . Are seeking to participate in the long term growth potential of U.S. stocks

 . Are looking for an investment with potentially greater return but higher risk
  than a fund investing primarily in fixed income securities

 . Are willing to accept the risks of the stock market

Principal Risks

As with any mutual fund, you may lose money if you invest in the Fund. The
Fund's principal risks are:

Index Investing Risk Because the Fund is managed as an index fund, it will not
ordinarily sell a portfolio security because of the security's poor perfor-
mance. The Fund normally buys or sells a portfolio security only to reflect
additions or deletions of stocks that comprise its Index or to adjust their
relative weightings. Although the manager seeks to replicate the performance of
the Index, the Fund may underperform its Index even before deducting fees and
expenses because the Fund must maintain a portion of its assets in liquid
short-term debt securities which historically have generated significantly
lower returns than common stocks. In addition, expenses and transaction costs,
the size of the Fund and the size and frequency of cash flows into and out of
the Fund, and the differences between how and when the Fund and its Index are
valued can also cause differences in performance. Because the Fund uses a sam-
pling strategy, it may not track its Index perfectly and differences between
the underlying Index and the Fund's portfolio will cause differences in perfor-
mance.

Market Risk The Fund is exposed to the risks of investing in common stocks. The
Fund may not perform as well as other investments, if, among other things: the
Index declines or performs poorly relative to other related indexes or individ-
ual securities; an adverse event, such as an unfavorable earnings report, nega-
tively affects the price of an issuer in the Index; or the securities issued by
companies which comprise the Index fall out of favor with investors.


Derivatives In seeking to match the performance of their Indexes, the Master
Portfolios may engage in futures and options transactions and other derivative
securities transactions which involve risk. The futures contracts and options
on futures contracts the Master Portfolios may purchase are considered deriva-
tives.

Derivatives may be more sensitive than direct securities to changes in interest
rates or sudden market moves. Some derivatives also may be susceptible to fluc-
tuations in yield or value because of their structure or contract terms. Even a
small investment in derivative contracts can have a big impact on the Fund's
stock market exposure. Therefore, using derivatives can disproportionately
increase losses and reduce opportunities for gains when stock prices are chang-
ing. The Fund may not fully benefit from or may lose money on derivatives if
changes in their value do not correspond accurately to changes in the value of
the Fund's holdings. This may adversely affect the Fund's ability to track its
Index.

Certain derivative contracts present the risk that the other party to the con-
tract may not perform. Derivatives can also make the Fund less liquid and
harder to value, especially in declining markets.

This example is intended to help you compare the cost of investing in the Fund
to the cost of investing in other mutual funds. The example assumes that:

 .you invest $10,000 in the Fund for the time periods indicated;

 .you reinvest all dividends;

 .you then sell all of your shares at the end of those periods;

 .your investment has a 5% return each year--the assumption of a 5% return is
  required by the SEC for the purpose of this example and is not a prediction
  of the Fund's future performance; and

 .the Fund's operating expenses as shown in the table remain the same--the exam-
  ple reflects the cap on operating expenses.

Smith Barney International Index Shares

The Fund's goal is to provide long-term capital growth and diversification by
approximating, before fees and expenses, the performance of the Morgan Stanley
Capital International Europe, Australasia, and Far East Free Index (MSCI
EAFE(R) Free Index).

The Fund invests all of its assets in a separate mutual fund, called a Master
Portfolio, that has a substantially identical investment objective. For
simplicity's sake, all discussions of investment objectives, strategies and
risks of the Fund refers also to the objectives, strategies and risks of its
corresponding Master Portfolio, unless otherwise indicated.

The Index

The MSCI EAFE(R) Free Index is a broadly diversified index of approximately
1100 securities that are listed on the stock exchanges of European countries
and Australia, New Zealand, Hong Kong, Japan, and Singapore and that is
intended to represent broadly the performance of foreign stock markets. The
Index is market-value weighted, so the larger of the companies included in the
Index have a greater impact on the performance of the Index than the smaller
companies. For this reason, issuers from certain countries or regions could be
disproportionately represented in the Index from time to time. The MSCI EAFE(R)
Free Index does not show actual investment returns or reflect payment of man-
agement or brokerage fees, which would lower the Index's performance. The MSCI
EAFE(R) Free Index is unmanaged and does not have to maintain liquidity to meet
redemption requests or pay expenses.

Principal Strategies

Key investments The International Index Fund invests in a sampling of securi-
ties that are selected and weighted to result in investment characteristics
comparable to, and performance that will correlate with the performance before
fees and expenses of, the MSCI EAFE(R) Free Index. The statistical sampling
techniques are based on capitalization, industry exposures, dividend yield,
price/earnings ratio, price/book ratio, earnings growth, country weightings and
the effect of foreign taxes. Under normal market conditions, the Fund invests
at least 90% of its assets in common stocks included in the MSCI EAFE(R) Free
Index. The Fund attempts to achieve, in both rising and falling markets, a cor-
relation of at least 95% between the total return of its net assets before fees
and expenses and the Index.

Selection process The International Index Fund's manager follows an indexed or
"passively managed" approach to investing. This means that the manager does not
evaluate individual companies to identify attractive investment candidates.
Instead, the manager attempts to mirror the performance of the Index as closely
as possible by adjusting the Fund's portfolio

Index Funds

16
<PAGE>


periodically to reflect a sampling of the companies included in the Index and
their weightings. Like most index funds, the Fund does not mirror the Index
exactly because, unlike the Index, the Fund must maintain a portion of its
assets in cash and liquid short-term securities to meet redemption requests and
pay the Fund's expenses. The Fund's returns are likely to be below those of the
Index because of the Fund's short-term investments and its operating expenses.



Investment Structure The International Index Fund is structured as a feeder
fund. The Fund does not buy individual securities directly. Instead, it invests
all of its assets in a corresponding Master Portfolio, International Index Mas-
ter Portfolio. The Master Portfolio invests in securities in accordance with
investment goals, policies and limitations that are similar to those of the
Fund.

As other investors invest their assets in the Master Portfolio, certain eco-
nomic efficiencies may be realized with respect to the Master Portfolio. For
example, fixed expenses that otherwise would have been borne solely by the Fund
(and the other existing interestholders in the Master Portfolio) would be
spread across a larger asset base as more funds invest in the Master Portfolio.
However, if a mutual fund or other investor withdraws its investment from the
Master Portfolio, the economic efficiencies that should be available through
investment in the Master Portfolio may not be fully achieved or maintained. In
addition, given the relatively complex nature of the master/feeder structure,
accounting and operational difficulties could occur. For example, coordination
of calculation of net asset value could be affected at the master and/or feeder
level.

The International Index Fund may withdraw its investment in its Master Portfo-
lio, without a shareholder vote, if the Board of Trustees determines that it is
in the best interests of the Fund and its shareholders to do so. Upon any such
withdrawal, the Board would consider what action might be taken, including the
investment of all the assets of the Fund in another pooled investment entity
having the same investment objective as the Fund or the hiring of a subadviser
to manage the Fund's assets.

Who may want to invest

The International Index Fund may be an appropriate investment if you:

 . Are seeking to participate in the long term growth potential of international
  markets

 . Currently have exposure to U.S. stock markets and wish to diversify your
  investment portfolio by adding non-U.S. stocks that may not move in tandem
  with U.S. stocks

 . Are comfortable with the risks of the stock market and the special risks of
  investing in foreign securities, including emerging market securities

Principal Risks

As with any mutual fund, you may lose money if you invest in the Fund. The
Fund's principal risks are:

Index Investing Risk Because the Fund is managed as an index fund, it will not
ordinarily sell a portfolio security because of the security's poor perfor-
mance. The Fund normally buys or sells a portfolio security only to reflect
additions or deletions of stocks that comprise its Index or to adjust their
relative weightings. Although the manager seeks to replicate the performance of
the Index, the Fund may underperform its Index even before deducting fees and
expenses because the Fund must maintain a portion of its assets in liquid
short-term debt securities which historically have generated significantly
lower returns than common stocks. In addition, expenses and transaction costs,
the size of the Fund and the size and frequency of cash flows into and out of
the Fund, and the differences between how and when the Fund and its Index are
valued can also cause differences in performance. Because the Fund may use a
sampling strategy, it may not track its Index perfectly and differences between
the underlying Index and the Fund's portfolio will cause differences in perfor-
mance.

Market Risk The Fund is exposed to the risks of investing in common stocks. The
Fund may not perform as well as other investments, if, among other things: the
Index declines or performs poorly relative to other related indexes or individ-
ual securities; an adverse event, such as an unfavorable earnings report, nega-
tively affects the price of an issuer in the Index; or the securities issued by
companies which comprise the Index fall out of favor with investors.

Derivatives In seeking to match the performance of its Index, International
Index Master Portfolio may engage in futures and options transactions and other
derivative securities transactions which involve risk. The futures contracts
and options on futures contracts the Master Portfolio may purchase are consid-
ered derivatives.

Derivatives may be more sensitive than direct securities to changes in interest
rates or sudden market moves. Some derivatives also may be susceptible to fluc-
tuations in yield or value because of their structure or contract terms. Even a
small investment in derivative contracts can have a big impact on the Fund's
stock market exposure. Therefore, using derivatives can disproportionately
increase losses and reduce opportunities for gains when stock prices are chang-
ing. The Fund may not fully benefit from or may lose money on derivatives if
changes in their value do not correspond accurately to changes in the value of
the Fund's holdings. This may adversely affect the Fund's ability to track its
Index.

Index Funds

<PAGE>


Certain derivative contracts present the risk that the other party to the con-
tract may not perform. Derivatives can also make the Fund less liquid and
harder to value, especially in declining markets.

Foreign Securities The Fund is exposed to the risks of investing in foreign
securities, which can be affected by currency, political, legal, regulatory and
operational factors. Foreign markets can be less liquid and more volatile than
the U.S. market because of increased risks of adverse issuer, political, regu-
latory, market or economic developments and can perform differently than the
U.S. market. In some foreign countries, there is also less information avail-
able about foreign issuers and markets because of less rigorous accounting and
regulatory standards than in the U.S. The value of securities of smaller, less
well-known issuers can perform differently than the market as a whole and other
types of stocks and can be more volatile than that of larger issuers. Because
the value of ADRs, in which the Fund may invest, is dependent upon the market
price of an underlying foreign security, ADRs are subject to most of the risks
associated with foreign investing. The Fund may lose money if the currency in
which a security is priced declines in value relative to the U.S. dollar. Cur-
rency fluctuations could erase investment gains or add to investment losses.

More on the Fund's Investments and Risks

Money Market Instruments

The Fund may temporarily invest in money market instruments. The Fund invests
in money market instruments pending investment of proceeds of the sale of
shares of the Fund or settlement of purchases of securities by the Fund or to
maintain liquidity to meet anticipated redemptions. The Fund's investments in
money market instruments will likely cause the Fund's returns to differ from
those of the Index.

Smith Barney U.S. 1000 Index Shares

The Fund's goal is to provide investment results that, before fees and
expenses, correspond to the performance of the Russell 1000(R) Index.

The Index

The Russell 1000 Index measures the performance of the 1,000 largest U.S. pub-
lic companies based on total market capitalization. As of May 31, 2000, the
average market capitalization of companies in the Russell 1000 Index was
approximately $14.1 billion, and the smallest company in the Russell 1000 Index
had a market capitalization of approximately $1.6 billion. The Russell 1000
Index does not show actual investment returns or reflect payment of management
or brokerage fees, which would lower the Russell 1000 Index's performance. The
Russell 1000 Index is unmanaged and does not have to maintain liquidity to meet
redemption requests or pay expenses.

Principal Strategies

Key investments The U.S. 1000 Index Fund may use replication or sampling tech-
niques to track the performance of the Russell 1000 Index. The Fund may use
derivatives and investment techniques such as buying and selling options and
futures contracts, entering into swap agreements and purchasing indexed securi-
ties to track the performance of the Russell 1000 Index. The Fund also may
enter into repurchase agreements and lend portfolio securities.

Selection process The U.S. 1000 Index Fund is a "pure" index Fund. This means
that the manager does not evaluate individual companies to identify attractive
investment candidates. Instead, the manager attempts to mirror the performance
of the Index as closely as possible by adjusting the Fund's portfolio periodi-
cally to match or sample the Index or its performance. Like most index funds,
the Fund does not mirror the Index exactly, because, unlike the Index, the Fund
must maintain a portion of its assets in cash and liquid short-term securities
to meet redemption requests and pay the Fund's expenses. The Fund's returns are
likely to be below those of the Index because of the Fund's short-term invest-
ments and its operating expenses.

Who may want to invest

The U.S. 1000 Index Fund may be an appropriate investment if you:

 . Are seeking to participate in the long-term growth potential of U.S. large
  capitalization stocks

                                                  Smith Barney Mutual Funds

                                                                              23
<PAGE>


 . Are looking for an investment with potentially greater return but higher risk
  than a fund investing primarily in fixed income securities

 . Are willing to accept the risks of the stock market

Principal Risks

As with any mutual fund, you may lose money if you invest in the Fund. The
Fund's principal risks are:

Index Investing Risk Because the Fund is managed as an index fund, it will not
ordinarily sell a portfolio security because of the security's poor perfor-
mance. The Fund normally buys or sells a portfolio security only to reflect
additions or deletions of stocks that comprise its Index or to adjust their
relative weightings. Although the manager seeks to replicate the performance of
the Index, the Fund may underperform its Index even before deducting fees and
expenses because the Fund must maintain a portion of its assets in liquid
short-term debt securities which historically have generated significantly
lower returns than common stocks. In addition, expenses and transaction costs,
the size of the Fund and the size and frequency of cash flows into and out of
the Fund, and the differences between how and when the Fund and its Index are
valued can also cause differences in performance. Because the Fund may use a
sampling strategy, it may not track its Index perfectly and differences between
the underlying Index and the Fund's portfolio will cause differences in perfor-
mance.

Market Risk The Fund is exposed to the risks of investing in common stocks. The
Fund may not perform as well as other investments, if, among other things: the
Index declines or performs poorly relative to other related indexes or individ-
ual securities; an adverse event, such as an unfavorable earnings report, nega-
tively affects the price of an issuer in the Index; or the securities issued by
companies which comprise the Index fall out of favor with investors.

Derivatives Derivatives may be more sensitive than direct securities to changes
in interest rates or sudden market moves. Some derivatives also may be suscep-
tible to fluctuations in yield or value because of their structure or contract
terms. Even a small investment in derivative contracts can have a big impact on
the Fund's stock market exposure. Therefore, using derivatives can dispropor-
tionately increase losses and reduce opportunities for gains when stock prices
are changing. The Fund may not fully benefit from or may lose money on deriva-
tives if changes in their value do not correspond accurately to changes in the
value of the Fund's holdings. This may adversely affect the Fund's ability to
track its Index.

Index Funds

<PAGE>


Certain derivative contracts present the risk that the other party to the con-
tract may not perform. Derivatives can also make the Fund less liquid and
harder to value, especially in declining markets.

Non-Diversification The Fund is "non-diversified", which means it may invest a
relatively high percentage of its assets in the securities of a single issuer
or a limited number of issuers. As a result, the Fund may be more sensitive to
a single economic, political or regulatory occurrence than a diversified fund.

More on the Fund's Investments and Risks

Money Market Instruments

The Fund may temporarily invest in money market instruments. The Fund invests
in money market instruments pending investment of proceeds of the sale of
shares of the Fund or settlement of purchases of securities by the Fund or to
maintain liquidity to meet anticipated redemptions. The Fund's investments in
money market instruments will likely cause the Fund's returns to differ from
those of the Index.

Securities Lending

If the Fund lends its securities to earn income, it will receive cash or other
securities as collateral for the loan, which must be returned to the borrower
at the completion of the loan. The Fund typically invests cash collateral
received in short-term investments. The Fund could lose money if the lent secu-
rities are not returned by the borrower at the termination of the loan, or if
the value of its short-term investment of the cash collateral declines over the
period of the loan.

Investment Structure

U.S. 1000 Index Fund invests directly in securities, but may, in the future,
invest in securities through one or more underlying mutual funds, or portfo-
lios.

Fund Performance

Because the Fund is a new fund, performance information for the Fund is not
included in this prospectus.

(2) Management has agreed to cap the Fund's other expenses at 0.25%. This cap
    is voluntary and may be modified or terminated at any time.

Expenses on a $10,000 investment

This example is intended to help you compare the cost of investing in the Fund
to the cost of investing in other mutual funds. The example assumes that:

 . you invest $10,000 in the Fund for the time periods indicated;

 . you reinvest all dividends;

 . you then sell all of your shares at the end of those periods;

 . your investment has a 5% return each year--the assumption of a 5% return is
  required by the SEC for the purpose of this example and is not a prediction
  of the Fund's future performance; and

 . the Fund's operating expenses as shown in the table remain the same--the
  example does not include voluntary fee caps.

Although your actual costs may be higher or lower, based on these assumptions
your costs would be:

More About the Index

The chart below sets forth the annual total returns of the Russell 1000 Index
for each of the past ten calendar years. The data is provided to illustrate the
past performance of the Fund's Index and does not represent the performance of
the Fund. Investors should not consider this performance data as an indication
of future performance of the Fund. The returns are not intended to predict or
suggest the returns that might be experienced by the Fund or an individual
investing in the Fund.

All returns presented were calculated on a total return basis, which includes
the reinvestment of all distributions. Performance of the Fund for the periods
shown below would have been lower because of the operating expenses associated
with an investment in the Fund.

Smith Barney Small Cap Index Shares

The Fund's goal is to provide investment results that, before fees and
expenses, correspond to the performance of the Russell 2000(R) Index.

The Index

The Russell 2000 Index is comprised of the 2,000 smallest companies out of the
3,000 largest U.S. public companies based on total market capitalization. As of
May 31, 2000, the average market capitalization of companies in the Russell
2000 Index was approximately $580 million, and the largest company in the Index
had a market capitalization of approximately $1.5 billion. The Russell 2000
Index does not show actual investment returns or reflect payment of management
or brokerage fees, which would lower the Russell 2000 Index's performance. The
Russell 2000 Index is unmanaged and does not have to maintain liquidity to meet
redemption requests or pay expenses.

Principal Strategies

Key investments The Small Cap Index Fund may use replication or sampling tech-
niques to track the performance of the Russell 2000 Index. The Fund also may
use derivatives and investment techniques such as buying and selling options
and futures contracts, entering into swap agreements and purchasing indexed
securities to track the performance of the Index. The Fund also may enter into
repurchase agreements and lend portfolio securities.

Selection process The Small Cap Index Fund is a "pure" index Fund. This means
that the manager does not evaluate individual companies to identify attractive
investment candidates. Instead, the manager attempts to mirror the performance
of the Index as closely as possible by adjusting the Fund's portfolio periodi-
cally to match or sample the Index or its performance. Like most index funds,
the Fund does not mirror the Index exactly, because, unlike the Index, the Fund
must maintain a portion of its assets in cash and liquid short-term securities
to meet redemption requests and pay the Fund's expenses. The Fund's returns are
likely to be below those of the Russell 2000 Index because of the Fund's short-
term investments and its operating expenses.

  capitalization stocks

Principal Risks

As with any mutual fund, you may lose money if you invest in the Fund. The

Market Risk The Fund is exposed to the risks of investing in common stocks. The
Fund may not perform as well as other investments, if, among other things: the

nies.

Expenses on a $10,000 investment

This example is intended to help you compare the cost of investing in the Fund
to the cost of investing in other mutual funds. The example assumes that:

 . you invest $10,000 in the Fund for the time periods indicated;

 . you reinvest all dividends;

 . you then sell all of your shares at the end of those periods;

 . your investment has a 5% return each year--the assumption of a 5% return is
  required by the SEC for the purpose of this example and is not a prediction
  of the Fund's future performance; and

 . the Fund's operating expenses as shown in the table remain the same--the
  example does not include voluntary fee caps.

Although your actual costs may be higher or lower, based on these assumptions
your costs would be:

More About the Index

The chart below sets forth the annual total returns of the Russell 2000 Index
over each of the past ten calendar years. The line graph below shows the growth
of a $10,000 investment in the stocks comparing the Index over the past ten
calendar years. The data is provided to illustrate the past performance of the
Fund's Index and does not represent the performance of the Fund. Investors
should not consider this performance data as an indication of future perfor-
mance of the Fund. The returns are not intended to predict or suggest the
returns that might be experienced by the Fund or an individual investing in the
Fund.

All returns presented were calculated on a total return basis, which includes
the reinvestment of all distributions. Performance of the Fund for the periods
shown below would have been lower because of the operating expenses associated
with an investment in the Fund.

Smith Barney Global Titans Index Shares

The Fund's goal is to provide investment results that, before fees and
expenses, correspond to the performance of the Dow Jones Global Titans Index SM
(Global Titans Index).

The Index

The Global Titans Index consists of securities of 50 companies, and includes
some of the world's most well-known and well-established blue-chip companies.
The Global Titans Index includes only the largest of large-cap companies in the
world and currently consists of stocks of companies with capitalizations of at
least $20 billion. The Global Titans Index began to be calculated in July 1999
and consists of securities of companies that are selected based on a global or
multi-national standard and, therefore, (1) may be headquartered anywhere in
the world; (2) are market and industry leaders on a global level, rather than
merely at a local level; and (3) have international exposure either from sell-
ing products outside their home markets or providing services to overseas cli-
ents. The companies whose securities comprise the Global Titans Index are
selected from the 100 largest companies in the world, as measured by assets,
book value, sales/revenue, net profit and foreign sales rankings.

Principal Strategies

Key investments The Global Titans Index Fund may use replication or sampling
techniques to track the performance of the Global Titans Index. The Fund also
may use derivatives and investment techniques such as buying and selling
options and futures contracts, entering into swap agreements and purchasing
indexed securities to track the performance of the Global Titans Index. The
Fund also may enter into repurchase agreements and lend portfolio securities.

Selection process The Global Titans Index Fund is a "pure" index Fund. This
means that the manager does not evaluate individual companies to identify
attractive investment candidates. Instead, the manager attempts to mirror the
performance of the Index as closely as possible by adjusting the Fund's portfo-
lio periodically to match or sample the Index or its performance. Like most
index funds, the Fund does not mirror the Index exactly. Also, unlike the
Index, the Fund must maintain a portion of its assets in cash and liquid short-
term securities to meet redemption requests and pay the Fund's expenses. The
Fund's returns are likely to be below those of the Index because of the Fund's
short-term investments and its operating expenses.

                                                  Smith Barney Mutual Funds

                                                                              35

Who may want to invest

The Global Titans Index Fund may be an appropriate investment if you:

 . Are seeking to participate in the long-term growth potential of U.S. and for-
  eign large capitalization stocks

 . Are looking for an investment with potentially greater return but higher risk
  than a Fund investing primarily in fixed income securities

 . Are willing to accept the risks of the stock markets worldwide, including the
  special risks of investing in foreign securities

Principal Risks

As with any mutual fund, you may lose money if you invest in the Fund. The
Fund's principal risks are:

Index Investing Risk Because the Fund is managed as an index fund, it will not
ordinarily sell a portfolio security because of the security's poor perfor-
mance. The Fund normally buys or sells a portfolio security only to reflect
additions or deletions of stocks that comprise its Index or to adjust their
relative weightings. Although the manager seeks to replicate the performance of
the Index, the Fund may underperform its Index even before deducting fees and
expenses because the Fund must maintain a portion of its assets in liquid
short-term debt securities which historically have generated significantly
lower returns than common stocks. In addition, expenses and transaction costs,
the size of the Fund and the size and frequency of cash flows into and out of
the Fund, and the differences between how and when the Fund and its Index are
valued can also cause differences in performance. Because the Fund may use a
sampling strategy, it may not track its Index perfectly and differences between
the underlying Index and the Fund's portfolio will cause differences in perfor-
mance.

Market Risk The Fund is exposed to the risks of investing in common stocks. The
Fund may not perform as well as other investments, if, among other things: the
Index declines or performs poorly relative to other related indexes or individ-
ual securities; an adverse event, such as an unfavorable earnings report, nega-
tively affects the price of an issuer in the Index; or the securities issued by
companies which comprise the Index fall out of favor with investors.

Derivatives Derivatives may be more sensitive than direct securities to changes
in interest rates or sudden market moves. Some derivatives also may be suscep-
tible to fluctuations in yield or value because of their structure or contract
terms. Even a small investment in derivative contracts can have a big impact on
the Fund's stock market exposure. Therefore, using

Index Funds

36
<PAGE>


derivatives can disproportionately increase losses and reduce opportunities for
gains when stock prices are changing. The Fund may not fully benefit from or
may lose money on derivatives if changes in their value do not correspond accu-
rately to changes in the value of the Fund's holdings. This may adversely
affect the Fund's ability to track its Index.

Certain derivative contracts present the risk that the other party to the con-
tract may not perform. Derivatives can also make the Fund less liquid and
harder to value, especially in declining markets.

Non-Diversification The Fund is "non-diversified", which means it may invest a
relatively high percentage of its assets in the securities of a single issuer
or a limited number of issuers. As a result, the Fund may be more sensitive to
a single economic, political or regulatory occurrence than a diversified fund.

Foreign Securities The Fund may purchase common stocks and ADRs of the foreign
companies included in its Index. ADRs are U.S. dollar-denominated securities
which represent an interest in an underlying foreign security. The Fund is
exposed to the risks of investing in foreign securities, which can be affected
by currency, political, legal, regulatory and operational factors. Foreign mar-
kets can be less liquid and more volatile than the U.S. market because of
increased risks of adverse issuer, political, regulatory, market or economic
developments and can perform differently that the U.S. market. In some foreign
countries, there is also less information available about foreign issuers and
markets because of less rigorous accounting and regulatory standards than in
the U.S. Because the value of ADRs, in which the Fund may invest, is dependent
upon the market price of an underlying foreign security, ADRs are subject to
most of the risks associated with foreign investing. The Fund may lose money if
the currency in which a security is priced declines in value relative to the
U.S. dollar. Currency fluctuations could erase investment gains or add to
investment losses.

More on the Fund's Investments and Risks

Money Market Instruments

The Fund may temporarily invest in money market instruments. The Fund invests
in money market instruments pending investment of proceeds of the sale of
shares of the Fund or settlement of purchases of securities by the Fund or to
maintain liquidity to meet anticipated redemptions. The Fund's investments in
money market instruments will likely cause the Fund's returns to differ from
those of the Index.

<PAGE>


Securities Lending

If the Fund lends its securities to earn income, it will receive cash or other
securities as collateral for the loan, which must be returned to the borrower
at the completion of the loan. The Fund typically invests cash collateral
received in short-term investments. The Fund could lose money if the lent secu-
rities are not returned by the borrower at the termination of the loan, or if
the value of its short-term investment of the cash collateral declines over the
period of the loan.

Investment Structure

Global Titans Index Fund invests directly in securities, but may, in the
future, invest in securities through one or more underlying mutual funds, or
portfolios.

Fund Performance

Because the Fund is a new fund, performance information for the Fund is not
included in this prospectus.

 . the Fund's operating expenses as shown in the table remain the same--the
  example does not include voluntary fee caps.

More About the Index

Dow Jones, the sponsor of the Global Titans Index, calculates the value of the
Index at three different times during the day, based on the close of various
markets world-wide. For the purposes of tracking the performance of its bench-
mark Index, the Fund will use the value of the Index calculated at the close of
the U.S. markets.

Performance for the Dow Jones Global Titans Index is not presented because this
Index has been in existence only since July, 1999.

Smith Barney Nasdaq-100 Index Shares

The Fund's goal is to provide investment results that, before fees and
expenses, correspond to the performance of the Nasdaq-100 Index(R).

The Index

The Nasdaq-100 Index includes the largest (based on market capitalization) and
most active non-financial domestic and international stocks listed on The
Nasdaq Stock Market. The Nasdaq-100 Index does not show actual investment
returns or reflect payment of management or brokerage fees, which would lower
the Nasdaq-100 Index's performance. The Nasdaq-100 Index is unmanaged and does
not have to maintain liquidity to meet redemption requests or pay expenses.

Principal Strategies

Key investments The Nasdaq-100 Fund may use replication or sampling techniques
to track the performance of the Nasdaq-100 Index. The Fund also may use deriva-
tives and investment techniques such as buying and selling options and futures
contracts, entering into swap agreements and purchasing indexed securities to
track the performance of the Index. The Fund also may enter into repurchase
agreements and lend portfolio securities.

Selection process The Nasdaq-100 Fund is a "pure" index Fund. This means that
the manager does not evaluate individual companies to identify attractive
investment candidates. Instead, the manager attempts to mirror the performance
of the Index as closely as possible by adjusting the Fund's portfolio periodi-
cally to match or sample the Index or its performance. Like most index funds,
the Fund does not mirror the Index exactly, because, unlike the Index, the Fund
must maintain a portion of its assets in cash and liquid short-term securities
to meet redemption requests and pay the Fund's expenses. The Fund's returns are
likely to be below those of the Index because of the Fund's short-term invest-
ments and its operating expenses.

Who may want to invest

The Nasdaq-100 Fund may be an appropriate investment if you:

 . Are seeking to participate in the long term growth potential of U.S. stocks

 . Are looking for an investment with potentially greater return but higher risk
  than a Fund investing primarily in fixed income securities

Principal Risks

As with any mutual fund, you may lose money if you invest in the Fund. The
Fund's principal risks are:

ual securities; an adverse event, such as an unfavorable earnings report, nega-
tively affects the price of an issuer in the Index; or the securities issued by
companies which comprise the Index fall out of favor with investors.

Technology Risk Although the composition of the Index changes from time to
time, many of the stocks in the Index may be issued by companies in the tech-
nology sector. Market conditions, interest rates, and economic, regulatory or
financial developments could significantly affect the technology sector and the
securities of companies in that sector could react similarly to these or other
developments. Technology companies can be significantly affected by obsoles-
cence of existing technology, short product cycles, falling prices and profits,
and competition from new market entrants. The technology sector may be subject
to greater governmental regulation than many other areas, and changes in gov-
ernmental policies and the need for regulatory approvals may have a material
adverse effect

on the sector. The performance of the technology sector may differ in direction
and degree from that of the overall stock market.

Derivatives Derivatives may be more sensitive than direct securities to changes
in interest rates or sudden market moves. Some derivatives also may be suscep-
tible to fluctuations in yield or value because of their structure or contract

tract may not perform. Derivatives can also make the Fund less liquid and
harder to value, especially in declining markets.

relatively high percentage of its assets in the securities of a single issuer
or a limited number of issuers. As a result, the Fund may be more sensitive to
a single economic, political or regulatory occurrence than a diversified fund.

Smaller Companies The Fund's investments may include smaller capitalization
companies whose stocks tend to have more price volatility than larger compa-
nies.

Securities Lending

If the Fund lends its securities to earn income, it will receive cash or other
securities as collateral for the loan, which must be returned to the borrower
at the completion of the loan. The Fund typically invests cash collateral
received in short-term investments. The Fund could lose money if the lent secu-
rities are not returned by the borrower at the termination of the loan, or if
the value of its short-term investment of the cash collateral declines over the
period of the loan.

Investment Structure

The Nasdaq-100 Index Fund invests directly in securities, but may, in the
future, invest in securities through one or more underlying mutual funds, or

Expenses on a $10,000 investment

This example is intended to help you compare the cost of investing in the Fund
to the cost of investing in other mutual funds. The example assumes that:

 . you invest $10,000 in the Fund for the time periods indicated;

 . you reinvest all dividends;

 . you then sell all of your shares at the end of those periods;

 . your investment has a 5% return each year--the assumption of a 5% return is
  required by the SEC for the purpose of this example and is not a prediction
  of the Fund's future performance; and

 . the Fund's operating expenses as shown in the table remain the same--the
  example does not include voluntary fee caps.

Although your actual costs may be higher or lower, based on these assumptions
your costs would be:

More About the Index

The chart below sets forth the annual returns of the Nasdaq 100 Index over each
of the past ten calendar years. The line graph below shows the growth of a
$10,000 investment in the stocks comparing the Index over the past ten calendar
years. The data is provided to illustrate the past performance of the Fund's
Index and does not represent the performance of the Fund. Investors should not
consider this performance data as an indication of future performance of the
Fund. The returns are not intended to predict or suggest the returns that might
be experienced by the Fund or an individual investing in the Fund. In particu-
lar, investors should note the performance of the Index for the past two calen-
dar years was exceptional and will not likely be repeated.

All returns presented were calculated on a total return basis which includes
the reinvestment of all distributions. Performance of the Fund for the periods
shown below would have been lower because of the operating expenses associated
with an investment in the Fund.

Smith Barney U.S. Bond Index Shares

The Fund's goal is to provide investment results that, before fees and
expenses, correspond to the performance of the Lehman Brothers Aggregate Bond
Index(R) (Lehman Bond Index).

The Index

The Lehman Bond Index measures the total universe of public investment-grade
fixed income securities in the U.S., including government, corporate, mortgage-
backed, asset-backed, and international U.S. dollar-denominated bonds, all with
maturities of over 1 year. As of December 31, 1999, the Lehman Bond Index
included more than 5,500 bonds. The Index does not show actual investment
returns or reflect payment of management or brokerage fees, which would lower
the Index's performance. The Index is unmanaged and does not have to maintain
liquidity to meet redemption requests or pay expenses.

Principal Strategies

Key investments The U.S. Bond Index Fund may use replication or sampling tech-
niques to track the performance of the Lehman Bond Index. The Fund also may use
derivatives and investment techniques such as buying and selling options and
futures contracts, entering into swap agreements and purchasing indexed securi-
ties to track the performance of the Index. The Fund also may enter into repur-
chase agreements and lend portfolio securities.

Selection process The U.S. Bond Index Fund is a "pure" index Fund. This means
that the manager does not evaluate individual bonds to identify attractive
investment candidates. Instead, the manager attempts to mirror the performance
of the Index as closely as possible by adjusting the Fund's portfolio periodi-
cally to reflect the companies included in the Index and their weightings. Like
most index funds, the Fund does not mirror the Index exactly because, unlike
the Index, the Fund must maintain a portion of its assets in cash and liquid
short-term securities to meet redemption requests and pay the Fund's expenses.
The Fund's returns are likely to be below those of the Index because of the
Fund's short-term investments and its operating expenses.

Who may want to invest

The U.S. Bond Index Fund may be an appropriate investment if you:

 . Are seeking to participate in the bond market

 . Are willing to accept the risks of the bond market

Principal Risks

As with any mutual fund, you may lose money if you invest in the Fund. The
Fund's principal risks are:

Index Investing Risk Because the Fund is managed as an index fund, it will not
ordinarily sell a portfolio security because of the security's poor perfor-
mance. The Fund normally buys or sells a portfolio security only to reflect
additions or deletions of securities that comprise its Index or to adjust their
relative weightings. Although the manager seeks to replicate the performance of
the Index, the Fund may underperform its Index even before deducting fees and
expenses because the Fund must maintain a portion of its assets in liquid
short-term debt securities which historically have generated lower returns than
longer term debt securities. In addition, expenses and transaction costs, the
size of the Fund and the size and frequency of cash flows into and out of the
Fund, and the differences between how and when the Fund and its Index are val-
ued can also cause differences in performance. Because the Fund may use a sam-
pling strategy, it may not track its Index perfectly and differences between
the underlying Index and the Fund's portfolio will cause differences in perfor-
mance.

Interest Rate Risk In general, the prices of debt securities rise when interest
rates fall, and fall when interest rates rise. Longer-term obligations are usu-
ally more sensitive to interest rate changes. A change in interest rates could
cause the Fund's share price to go down.

Credit Risk Some issuers may not make payments on debt securities held by the
Fund. Or, an issuer's financial condition may deteriorate, leading to greater
volatility in the price of the security and making the security more difficult
for the Fund to sell.

Income Risk If interest rates decline, the amount of income paid to you by the
Fund as dividends may also decline.


Prepayment and Extension Risk The issuers of debt securities held by the Fund
may be able to call a bond or prepay principal due on the securities, particu-
larly during periods of declining interest rates. The Fund may not be able to
reinvest that principal at attractive rates, and the Fund may lose any premium
paid. On the other hand, rising interest rates may cause prepayments to occur
at slower than expected rates. This makes securities more sensitive to interest
rate changes.

Market Risk The Fund may not perform as well as other investments, if, among
other things, the Index declines or performs poorly relative to other

                                                  Smith Barney Mutual Funds

                                                                              49
<PAGE>


related indexes or individual securities, or the securities issued by companies
which comprise the Index fall out of favor with investors.

Derivatives Derivatives may be more sensitive than direct securities to changes
in interest rates or sudden market moves. Some derivatives also may be suscep-
tible to fluctuations in yield or value because of their structure or contract
terms. Even a small investment in derivative contracts can have a big impact on
the Fund's bond market exposure. Therefore, using derivatives can dispropor-
tionately increase losses and reduce opportunities for gains when bond prices
are changing. The Fund may not fully benefit from or may lose money on deriva-
tives if changes in their value do not correspond accurately to changes in the
value of the Fund's holdings. This may adversely affect the Fund's ability to
track its Index.

Certain derivative contracts present the risk that the other party to the con-
tract may not perform. Derivatives can also make the Fund less liquid and
harder to value, especially in declining markets.

Non-Diversification The Fund is "non-diversified", which means it may invest a
relatively high percentage of its assets in the securities of a single issuer
or a limited number of issuers. As a result, the Fund may be more sensitive to
a single economic, political or regulatory occurrence than a diversified fund.


More on the Fund's Investments and Risks

Money market instruments

The Fund may temporarily invest in money market instruments. The Fund invests
in money market instruments pending investment of proceeds of the sale of
shares of the Fund or settlement of purchases of securities by the Fund or to
maintain liquidity to meet anticipated redemptions. The Fund's investments in
money market instruments will likely cause the Fund's returns to differ from
those of the Index.

Foreign investments

The Fund may purchase international U.S. dollar-denominated bonds included in
its Index. Foreign countries generally have markets that are less liquid and
more volatile than markets in the U.S. In some foreign countries, there is also
less information available about foreign issuers and markets because of less
rigorous accounting and regulatory standards than in the U.S.

Securities Lending

If the Fund lends its securities to earn income, it will receive cash or other
securities as collateral for the loan, which must be returned to the borrower
at the completion of the loan. The Fund typically invests cash collateral
received in short-term investments. The Fund could lose money if the lent secu-
rities are not returned by the borrower at the termination of the loan, or if
the value of its short-term investment of the cash collateral declines over the
period of the loan.

Investment Structure

U.S. Bond Index Fund invests directly in securities, but may, in the future,
invest in securities through one or more underlying mutual funds, or
portfolios.

Because the Fund is a new fund, performance information for the Fund is not

Expenses on a $10,000 investment

This example is intended to help you compare the cost of investing in the Fund
to the cost of investing in other mutual funds. The example assumes that:

 . you invest $10,000 in the Fund for the time periods indicated;

 . you reinvest all dividends;

 . you then sell all of your shares at the end of those periods;

 . your investment has a 5% return each year--the assumption of a 5% return is
  required by the SEC for the purpose of this example and is not a prediction
  of the Fund's future performance; and

 . the Fund's operating expenses as shown in the table remain the same--the
  example does not include voluntary fee caps.

Although your actual costs may be higher or lower, based on these assumptions
your costs would be:

U.S. 5000 Index Fund
International Index Fund

Manager U.S. 5000 Index Fund and International Index Fund are feeder funds in a
master/feeder structure. Accordingly, these funds do not buy individual securi-
ties directly. Barclays Global Fund Advisors (BGFA) is the manager of each of
the Master Portfolios in which the Funds invest. BGFA is a wholly owned direct
subsidiary of Barclays Global Investors, N.A. (which is an indirect subsidiary
of Barclays Bank PLC) and is located at 45 Fremont Street, San Francisco, CA
94105. BGFA has provided asset management, administration and advisory services
for over 25 years.

Management fees For the U.S. 5000 Index Fund, BGFA receives a monthly advisory
fee from the Master Portfolio at an annual rate equal to 0.01% of the US Equity
Index Master Portfolio's average daily net assets, 0.08% of the average daily
net assets of the Extended Index Master Portfolio and 0.05% of the average
daily net assets of the S&P 500 Index Master Portfolio. For the International
Index Fund, BGFA receives a monthly advisory fee from the International Index
Master Portfolio at an annual rate equal to 0.15% of the first $1 billion, and
0.10% thereafter, of the International Index Master Portfolio's average daily
net assets. From time to time, BGFA may waive such fees in whole or in part.

Each Fund bears a pro rata portion of the investment advisory fees paid by the
Master Portfolio as well as certain other fees paid by the Master Portfolio,
such as accounting, legal and Securities and Exchange Commission registration
fees.

Administrator The Funds' administrator is SSB Citi.

Administration fees For its services, SSB Citi receives a fee equal on an
annual basis to 0.15% of each of the U.S. 5000 Index and International Index
Funds' average daily net assets.

Distribution Arrangements

The Funds offer two classes of shares, Citi Index Shares and Smith Barney Index
Shares. These classes have different expense levels. Only Smith Barney Shares
are offered in this prospectus. The Funds do not charge any sales loads or
deferred sales loads or other fees in connection with the purchase of Smith
Barney Shares.

The distributor may make payments for distribution and/or shareholder servicing
activities out of its past profits and other available sources. The distributor
may also make payments for marketing, promotional or related expenses to deal-
ers. The amount of these payments is determined by the distributor and may be
substantial. SSB Citi or an affiliate may make similar payments under similar
arrangements.

Distribution plans Each Fund has adopted a Rule 12b-1 service plan for its
Smith Barney Shares. Under the plan, Smith Barney Shares pay a service fee for
the sale of shares and for services provided to shareholders. The fee for Smith
Barney Shares is an ongoing expense and, over time, may cost you more than
other types of sales charges.

Transfer agent and shareholder servicing agent Citi Fiduciary Trust Company
serves as each Fund's transfer agent and shareholder servicing agent (the
"transfer agent"). Pursuant to a sub-transfer agency and services agreement
with the transfer agent, Boston Financial Data Services serves as each Fund's
sub-transfer agent (the "sub-transfer agent"). The sub-transfer agent will per-
form certain functions including shareholder record keeping and account servic-
es.

 Smith Barney Shares

You may purchase Smith Barney Shares which are sold at net asset value with no
initial or deferred sales charge. Smith Barney Shares are subject to an ongoing
service fee.

You may buy shares from:

 .A broker-dealer, financial intermediary, financial institution or the distrib-
  utor's financial consultants (each called a "Service Agent")

 Redeeming shares

     Generally
                 Contact your Service Agent to redeem shares of a Fund.

                 The price of any redemption of Fund shares will be the NAV
                 the next time it is calculated after your redemption request
                 has been received in proper form by the Fund. Fund shares are
                 redeemed without a sales charge, but your redemption may be
                 subject to a redemption fee. As indicated in each Fund's fee
                 table, excluding the S&P 500 Index Fund and the U.S. Bond
                 Index Fund, each Fund charges a redemption fee, payable to
                 the Fund, on the sale or exchange of any shares that have
                 been held for less than 180 days. In attempting to minimize
                 this fee, a Fund will first sell any shares in your account
                 that are not subject to the fee. If you own your shares
                 through a 401(k) plan or an IRA account, you will not be
                 charged a fee when you redeem your shares. The Funds reserve
                 the right to change the redemption fee criteria.

                 If the shares are held by a fiduciary or corporation, other
                 documents may be required.

                 Your redemption proceeds will be sent within three business
                 days after your request is received in good order. However,
                 if you recently purchased your shares by check, your redemp-
                 tion proceeds will not be sent to you until your original
                 check clears, which may take up to 15 days.

                 If you have a brokerage account with a Service Agent, your
                 redemption proceeds will be placed in your account and not
                 reinvested without your specific instruction. In other cases,
                 unless you direct otherwise, your redemption proceeds will be
                 paid by check mailed to your address of record.

 Other things to know about share transactions

When you buy, exchange or redeem shares, your request must be in good order.
This means you have provided the following information without which your
request will not be processed:

 . Name of the Fund
 . Account number
 . Class of shares being bought, exchanged or redeemed
 . Dollar amount or number of shares being bought, exchanged or redeemed
 . Signature of each owner exactly as the account is registered

The Fund will try to confirm that any telephone exchange or redemption request
is genuine by recording calls, asking the caller to provide certain personal
identification information for your account, sending you a written confirmation
or requiring other confirmation procedures from time to time.

Signature guarantees To be in good order, your redemption request must include
a signature guarantee if you:

 . Are redeeming over $50,000

 . Are sending signed stock powers to the sub-transfer agent
 . Instruct the sub-transfer agent to mail the check to an address different
  from the one on your account
 . Changed your account registration
 . Want the check paid to someone other than the account owner(s)
 . Are transferring the redemption proceeds to an account with a different reg-
  istration

You can obtain a signature guarantee from most banks, dealers, brokers, credit
unions and federal savings and loan institutions, but not from a notary public.

Each Fund has the right to:

 . Suspend the offering of shares
 . Waive or change minimum and additional investment amounts
 . Reject any purchase or exchange order
 . Change, revoke or suspend the exchange privilege
 . Suspend telephone transactions
 . Suspend or postpone redemptions of shares on any day when trading on the New
  York Stock Exchange is restricted, or as otherwise permitted by the Securi-
  ties and Exchange Commission

 . Pay redemption proceeds by giving you securities. You may pay transaction
  costs to dispose of the securities.

Small account balances If your account falls below $500 ($250 for IRA accounts)
because of a redemption of Fund shares, a Fund may ask you to bring your
account up to $500. If your account is still below $500 after 60 days, the Fund
may close your account and send you the redemption proceeds.

Excessive exchange transactions SSB Citi may determine that a pattern of fre-
quent exchanges is detrimental to a Fund's performance and other shareholders.
Each Fund may limit additional purchases and/or exchanges by a shareholder.



 Dividends, distributions and taxes

Dividends

Each Fund's dividend policies are described below. Unless you choose to receive
your dividends in cash, you will receive them as full and fractional additional
Fund shares of the same class of shares that you hold.

Nasdaq-100 Index Fund

Small Cap Index Fund

U.S. 1000 Index Fund

Global Titans Index Fund

Each Fund pays substantially all of its net income (if any) from dividends and
interest to its shareholders of record as a dividend semi-annually during the
months of June and December.

Each Fund's net realized short-term and long-term capital gains, if any, will
be distributed to Fund shareholders at least annually, in December. Each Fund
may also make additional distributions to shareholders to the extent necessary
to avoid the application of the 4% non-deductible excise tax on certain undis-
tributed income and net capital gains of mutual funds.

S&P 500 Index Fund

U.S. 5000 Index Fund

International Index Fund

Each Fund generally pays dividends, if any, and makes capital gains distribu-
tions, if any, once a year, typically in December. Each Fund may pay

                                                  Smith Barney Mutual Funds

                                                                              63
<PAGE>


additional distributions and dividends at other times if necessary for the Fund
to avoid a federal tax. Each Fund expects distributions to be primarily from
capital gains.

U.S. Bond Index Fund

The U.S. Bond Index Fund pays substantially all of its net income (if any) from
dividends and interest to its shareholders of record as a dividend monthly.

The U.S. Bond Index Fund's net realized short-term and long-term capital gains,
if any, will be distributed to Fund shareholders at least annually, in Decem-
ber. The Fund may also make additional distributions to shareholders to the
extent necessary to avoid the application of the 4% non-deductible excise tax
on certain undistributed income and net capital gains of mutual funds.

Taxes

This discussion of taxes is very general. You should consult your own tax
adviser about your particular situation.

Taxation Of Distributions You will normally have to pay federal income taxes on
the distributions you receive from a Fund, whether you take the distributions
in cash or reinvest them in additional shares. Distributions designated by a
Fund as capital gain dividends are taxable as long-term capital gains. Other
distributions are generally taxable as ordinary income. Some distributions paid
in January may be taxable to you as if they had been paid the previous Decem-
ber. Each year the Funds will make available to you a report of your distribu-
tions for the prior year and how they are treated for federal tax purposes.

Fund distributions will reduce a Fund's net asset value per share. As a result,
if you buy shares just before a Fund makes a distribution, you may pay the full
price for the shares and then effectively receive a portion of the purchase
price back as a taxable distribution.

Backup Withholding The account application asks each new investor to certify
that the investor's Social Security or taxpayer identification number is cor-
rect and that the shareholder is not subject to 31% backup withholding for
failing to report income to the IRS. A Fund may be required to withhold (and
pay over to the IRS for your credit) 31% of certain distributions it pays you
if you fail to provide this information or otherwise violate IRS regulations.

Index Funds

64
<PAGE>


Foreign Shareholders Each Fund will withhold U.S. federal income tax payments
at the rate of 30% (or any lower applicable treaty rate) on taxable dividends
and other payments subject to withholding taxes that are made to persons who
are not citizens or residents of the United States. Distributions received from
a Fund by non-U.S. persons also may be subject to tax under the laws of their
own jurisdictions.

Taxation Of Transactions If you sell your shares of a Fund, or exchange them for
shares of another Fund, it is considered a taxable event. Depending on your
purchase price and the sales price of the shares you sell or exchange, you may
have a gain or loss on the transaction. You are responsible for any tax
liabilities generated by your transaction.

 Share price

You may buy, exchange or redeem shares at their net asset value next determined
after receipt of your request in good order. Fund shares are redeemed without a
sales charge, but your redemption may be subject to a redemption fee. See "Re-
deeming Shares" above for additional information. Each Fund's net asset value
is the value of its assets minus its liabilities. Net asset value is calculated
separately for each class of shares. Each Fund calculates its net asset value
every day the New York Stock Exchange is open. This calculation is done when
regular trading closes on the Exchange (normally 4:00 p.m., Eastern time). The
Exchange is closed on certain holidays listed in the SAI.

Each Fund's currency conversions are done when the London stock exchange
closes. When reliable market prices or quotations are not readily available, or
when the value of a security has been materially affected by events occurring
after a foreign exchange closes, a fund may price those securities at fair val-
ue. Fair value is determined in accordance with procedures approved by the
Fund's board. Each fund that uses fair value to price securities may value
those securities higher or lower than another fund using market quotations to
price the same securities.

International markets may be open on days when U.S. markets are closed and the
value of foreign securities owned by a Fund could change on days when you can-
not buy or redeem shares.

In order to buy, redeem or exchange shares at that day's price, you must place
your order with your Service Agent or the Fund's sub-transfer agent before the
New York Stock Exchange closes. If the Exchange closes early, you must place
your order prior to the actual closing time. Otherwise, you will receive the
next business day's price.

Service Agents must transmit all order to buy, exchange or redeem shares to the
Fund's sub-transfer agent before the sub-transfer agent's close of business.

U.S. 5000 Index Fund and International Index Fund

The Master Portfolio for each Fund is valued daily by the Master Portfolio and
a Master Portfolio's net asset value is part of the calculation of the fund's
net asset value.

The assets of each feeder fund include its investments in a Master Portfolio,
plus cash and any other assets. Each feeder fund's investment in a Master Port-
folio is valued at the feeder fund's proportionate interest in the net assets
of a Master Portfolio. Each Master Portfolio calculates the net assets on the
same days and at the same time as the Fund.

Each Master Portfolio's assets are valued based on current market prices. If
such prices are not readily available, BGFA estimates the securities' fair
value in accordance with guidelines approved by the applicable Master Portfo-
lio's Board of Trustees.

Salomon Smith Barney or members of the selling group must transmit all orders
to buy, exchange or redeem shares to the Fund's agent before the agent's close
of business.

 Financial highlights

The financial highlights tables are intended to help you understand the perfor-
mance of each class for the past 5 years (or since inception if less than 5
years). Certain information reflects financial results for a single share.
Total return represents the rate that a shareholder would have earned (or lost)
on a fund share assuming reinvestment of all dividends and distributions. The
information in the following tables was audited by KPMG LLP, independent
accountants, whose report, along with the fund's financial statements, are
included in the annual report (available upon request). No information is pres-
ent for Smith Barney U.S. 1000 Index Shares, Smith Barney Small Cap Index
Shares, Smith Barney Global Titans Index Shares, Smith Barney Nasdaq-100 Shares
and Smith Barney U.S. Bond Index Shares because none of these shares were out-
standing for the periods shown.
