Premier Selections All Cap Growth Fund
 Investments, risks and performance

The Premier Selections All Cap Growth Fund is made up of a Large Cap Growth
segment, a Mid Cap Growth segment and a Small Cap Growth segment (collectively
the "All Cap Growth Fund").

Investment objective
Long-term capital growth.

Principal investment strategies
Key investments
Large Cap Growth segment This segment invests primarily in equity securities of
companies with large market capitalizations. Large capitalization companies are
those whose market capitalization is within the market capitalization range of
companies in the Russell 1000 Growth Index (the "Index") at the time of this
segment's investment. The size of the companies in the Index changes with mar-
ket conditions and the size of the Index. Equity securities include U.S.
exchange-traded and over-the-counter common stocks, debt securities convertible
into equity securities, and warrants and rights relating to equity securities.

Mid Cap Growth segment This segment invests primarily in equity securities of
medium sized companies. Medium sized companies are those whose market capital-
ization is within the market capitalization range of companies in the S&P 400
MidCap Index at the time of this segment's investment. The size of the compa-
nies in the Index changes with market conditions and the composition of the
Index. Equity securities include exchange traded and over-the-counter common
stocks, preferred stocks, debt securities convertible into equity securities
and warrants and rights relating to equity securities.

Small Cap Growth segment This segment invests primarily in equity securities of
companies that possess a market capitalization within the market capitalization
range of companies in the Russell 2000 Growth Index (the "Index") at the time
of this segment's investment. The size of the companies in the Index changes
with market conditions and the composition of the Index. Equity securities
include exchange-traded and over-the-counter common stocks, preferred stocks,
debt securities convertible into equity securities and warrants and rights
relating to equity securities.

All segments
Foreign investments The All Cap Growth Fund may invest up to 25% of its assets
(at the time of investment) in foreign securities. The All Cap Growth

Fund may invest directly in foreign issuers or invest in depositary receipts.
The All Cap Growth Fund's investments in securities of foreign issuers involve
greater risk than investments in securities of U.S. issuers. Because the value
of a depositary receipt is dependent upon the market price of an underlying
foreign security, depositary receipts are subject to most of the risks associ-
ated with investing in foreign securities directly. Foreign countries generally
have markets that are less liquid and more volatile than markets in the U.S. In
some foreign countries, less information is available about foreign issuers and
markets because of less rigorous accounting and regulatory standards than in
the U.S. Currency fluctuations could erase investment gains or add to invest-
ment losses.

Selection process The All Cap Growth Fund's strategy is to combine the efforts
of three segment managers and to invest in the stock selections considered most
attractive in the opinion of each segment manager. Each segment manager builds
a portfolio of stocks which he believes will offer superior long-term capital
growth potential. The target allocations are 40% to the Large Cap Growth
segment and 30% to each of the Mid Cap and Small Cap Growth segments. In
connection with the execution of purchases and sales, each segment may hold
temporarily more or fewer assets than represented by its designated segment of
the All Cap Growth Fund's assets. The amount to be invested by the All Cap
Growth Fund in any particular security will be determined by SSB Citi Fund
Management LLC (the "Manager") based on the recommendation of the segment
managers.

In order to maintain approximately the target allocations of the All Cap Growth
Fund's assets among the three segment managers, the Manager will:

 . Divide all daily cash inflows (purchases and reinvested distributions) and
  outflows (redemptions and expense items) among the three segment managers, as
  appropriate

 . Rebalance the allocation of securities in the All Cap Growth Fund's portfolio
  at any time the percentage of the All Cap Growth Fund's portfolio invested in
  any of Large Cap, Mid Cap or Small Cap Growth segment's securities diverges
  by at least 10% from the target allocation for a period of more than 10 days

As a consequence of its efforts to maintain assets at targeted percentages, the
Manager will allocate assets and rebalance when necessary by (1) allocating
cash inflow to portfolio segments that are below their targeted percentages, or
(2) by selling securities in a portfolio segment that exceeds its targeted per-
centage with proceeds being reallocated to a portfolio segment that is below
its targeted percentage. Reallocations may result in early rec-

                                                       Smith Barney Mutual Funds

                                                                               3

ognition of taxable gains and in additional transaction costs to the extent the
sales of securities as part of these reallocations result in higher portfolio
turnover. In addition, if one segment manager buys a security during a time
frame when the other segment manager sells it, the net position of the All Cap
Growth Fund in the security may be approximately the same as it would have been
with a single segment manager and no such sale and purchase. The Manager will
consider these costs in determining the allocation and reallocation of assets.
Where possible, in these instances, the Manager will seek to avoid transaction
costs.

Large Cap Growth segment The Large Cap Growth segment manager emphasizes indi-
vidual security selection while diversifying this segment of the All Cap Growth
Fund's investments across industries, which may help to reduce risk. The Large
Cap Growth segment manager attempts to identify established large capitaliza-
tion companies with the highest growth potential. The Large Cap Growth segment
manager then analyzes each company in detail, ranking its management, strategy
and competitive market position. Finally, the Large Cap Growth segment manager
attempts to identify the best values available among the growth companies iden-
tified.

In selecting individual companies for investment, the Large Cap Growth segment
manager considers:

 . Favorable earnings prospects
 . Technological innovation
 . Industry dominance
 . Competitive products and services
 . Global scope
 . Long term operating history
 . Consistent and sustainable long-term growth in dividends and earnings per
  share
 . Strong cash flow
 . High return on equity
 . Strong financial condition
 . Experienced and effective management

Mid Cap Growth segment The Mid Cap Growth segment manager focuses on medium
capitalization companies that exhibit attractive growth characteristics. The
Mid Cap Growth segment manager selects individual "growth" stocks for invest-
ment in two ways: by identifying those companies which exhibit the most favora-
ble growth prospects and by identifying those companies in the Mid Cap Growth
segment's size range which have favorable valuations relative to their growth
characteristics. This strategy is commonly known as "growth at a reasonable
price" and offers investors style

<PAGE>

diversification. In selecting individual companies for investment, the Mid Cap
Growth segment manager considers:

 . Growth characteristics, including high historic growth rates and high rela-
  tive growth compared with companies in the same industry or sector
 . Increasing profits and sales
 . Competitive advantages that could be more fully exploited by a company
 . Skilled management committed to long-term growth
 . Potential for a long-term investment by this segment of the All Cap Growth
  Fund

The Mid Cap Growth segment manager uses fundamental research to find stocks
with strong growth potential and also uses quantitative analysis to determine
whether these stocks are relatively undervalued or overvalued compared to
stocks with similar fundamental characteristics. The Mid Cap Growth segment
manager's valuations determine whether and when this segment of the All Cap
Growth Fund will purchase or sell the stocks it identifies through fundamental
research.

Small Cap Growth segment The Small Cap Growth segment manager focuses on small
capitalization companies that exhibit attractive growth characteristics. The
Small Cap Growth segment manager selects individual stocks for investment by
identifying those companies which exhibit the most favorable growth prospects.
In selecting individual companies for investment, the Small Cap Growth segment
manager considers:

 . Growth characteristics, including high historic growth rates and high fore-
  casted growth of sales and profits and a high return on equity
 . Innovative companies at the cutting edge of positive and dynamic demographic
  and economic trends
 . Products and services that give the company a competitive advantage
 . Skilled management committed to long-term growth
 . Potential for a long-term investment by this segment of the All Cap Growth
  Fund

The Small Cap Growth segment manager uses a disciplined investment process to
identify small financially sound growth companies that exhibit the potential to
become much larger and more successful. Elements of this process include funda-
mental research, evaluation of key management and screening techniques.

Principal risks of investing in the All Cap Growth Fund
Investors could lose money on their investments in the All Cap Growth Fund, or
the All Cap Growth Fund may not perform as well as other investments, if:

 . U.S. stock markets decline, or perform poorly relative to other types of
  investments
 . An adverse company specific event, such as an unfavorable earnings report,
  negatively affects the stock price of a company in which the All Cap Growth
  Fund invests

 . Large capitalization stocks fall out of favor with investors
 . The segment manager's judgement about the attractiveness, growth prospects or
  potential appreciation of a particular stock proves to be incorrect
 . Medium or small capitalization stocks fall out of favor with investors.
  Because 30% of the All Cap Growth Fund's assets are invested primarily in
  medium capitalization companies and 30% of the All Cap Growth Fund's assets
  are invested primarily in small cap companies, an investment in the All Cap
  Growth Fund may be more volatile and more susceptible to loss than an invest-
  ment in a fund which invests primarily in large capitalization companies.
  Medium and small capitalization companies may have more limited product
  lines, markets and financial resources than large capitalization companies.
  They may have shorter operating histories and less mature businesses. While
  medium capitalization companies generally have more established businesses
  than small capitalization companies, the prices of medium capitalization com-
  pany stocks tend to be more volatile than the prices of large capitalization
  company stocks. In addition, small capitalization company stocks may be less
  liquid than large capitalization company stocks.
 . Key economic trends become materially unfavorable, such as rising interest
  rates and levels of inflation or slowdown of economic growth

Who may want to invest The All Cap Growth Fund may be an appropriate investment
if you:

 . Are seeking to participate in the long-term growth potential of the U.S.
  stock market
 . Are looking for an investment with potentially greater return but higher risk
  than fixed income investments
 . Are willing to accept the risks of the stock market
 . Are looking for an investment with potentially greater return but higher risk
  than a fund that invests primarily in large cap companies
 . Are seeking to participate in the long-term potential of small capitalization
  growth companies
 . Are willing to accept the special risks and potential long-term rewards of
  investing in smaller companies with limited track records
 . Are seeking diversification

 More on the All Cap Growth Fund's investments

All Segments

Derivatives and hedging techniques The All Cap Growth Fund may, but need not,
use derivative contracts, such as futures and options on securities, securities
indices or currencies; options on these futures; forward currency contracts;
and interest rate or currency swaps for any of the following purposes:

 . To hedge against the economic impact of adverse changes in the market value
  of its securities, because of changes in stock market prices, currency
  exchange rates or interest rates.
 . As a substitute for buying or selling securities.

A derivative contract will obligate or entitle the All Cap Growth Fund to
deliver or receive an asset or cash payment based on the change in value of one
or more securities, currencies or indices. Even a small investment in deriva-
tive contracts can have a big impact on the All Cap Growth Fund's stock market,
currency and interest rate exposure. Therefore, using derivatives can dispro-
portionately increase losses and reduce opportunities for gains when stock
prices, currency rates or interest rates are changing. The All Cap Growth 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 All Cap
Growth Fund's holdings.

The other parties to certain derivative contracts present the same types of
credit risk as issuers of fixed income securities. Derivatives can also make
the All Cap Growth Fund less liquid and harder to value, especially in declin-
ing markets.

Defensive Investing The All Cap Growth Fund may depart from its principal
investment strategies in response to adverse market, economic or political con-
ditions by taking temporary defensive positions in money market instruments and
short-term debt securities or cash. If the All Cap Growth Fund takes a tempo-
rary defensive position, it may be unable to achieve its investment goal.

Master/feeder option The All Cap Growth Fund may in the future seek to achieve
its investment objective by investing all of its net assets in another invest-
ment company having the same investment objective and substantially the same
investment policies and restrictions as those applicable to the All Cap Growth
Fund.

Premier Selections Global Growth Fund
 Investments, risks and performance

The Premier Selections Global Growth Fund is made up of a U.S. Equity segment
and an International Equity segment (collectively the "Global Growth Fund").

Investment objective
Long term capital growth.

Principal investment strategies
Key investments
U.S. Equity segment This segment invests primarily in common stocks of compa-
nies that the segment manager believes are experiencing, or will experience,
growth in earnings that exceeds the average rate of earnings growth of the com-
panies which comprise the Russell 2500 Growth Index. This segment of the Global
Growth Fund may invest in the securities of large, well-known companies which
offer prospects of long-term earnings growth. However, because higher earnings
growth rates are often achieved by small to medium-sized companies, a signifi-
cant portion of this segment's assets are invested in the securities of such
companies.

International Equity segment This segment invests primarily in equity securi-
ties of foreign companies. Equity securities include exchange traded and over-
the-counter common stocks and preferred shares, debt securities convertible
into equity securities, and warrants and rights relating to equity securities.
The Global Growth Fund may invest up to 15% of its assets (at the time of
investment) in issuers located or doing business in emerging markets. Emerging
market investments offer the potential of significant gains but also involve
greater risks than investing in more developed countries. Political or economic
instability, lack of market liquidity and government actions such as currency
controls or seizure of private businesses or property are more likely in emerg-
ing markets.

Selection process The Global Growth Fund's strategy is to combine the efforts
of two segment managers and to invest in the stock selections considered most
attractive in the opinion of each segment manager. Each segment manager builds
a portfolio of stocks which he believes will offer superior long-term capital
growth potential. The target allocations are 50% to the U.S. Equity segment and
50% to the International Equity segment. In connection with the execution of
purchases and sales, each segment may hold temporarily more or fewer assets
than represented by one-half of the Global Growth Fund's assets. The amount to
be invested by the Global Growth Fund in any particular security will be deter-
mined by the Manager based on the recommendation of the segment managers.

<PAGE>


In order to maintain an approximately equal division of all of the Global
Growth Fund's assets between the two segment managers, the Manager will:

 . Divide all daily cash inflows (purchases and reinvested distributions) and
  outflows (redemptions and expense items) between the two segment managers, as
  appropriate

 . Rebalance the allocation of securities in the Global Growth Fund's portfolio
  whenever the percentage of the Global Growth Fund's portfolio invested in
  either the U.S. or International Equity segment's securities equals or
  exceeds 60% of the Global Growth Fund's total assets invested in either seg-
  ment for a period of more than 10 days

As a consequence of its efforts to maintain assets at targeted percentages, the
Manager will allocate assets and rebalance when necessary by (1) allocating
cash inflow to the portfolio segment that is below its targeted percentage, or
(2) by selling securities in the portfolio segment that exceeds its targeted
percentage with proceeds being reallocated to the portfolio segment that is
below its targeted percentage. Reallocations may result in early recognition of
taxable gains and in additional transaction costs to the extent the sales of
securities as part of these reallocations result in higher portfolio turnover.
In addition, if one segment manager buys a security during a time frame when
the other segment manager sells it, the net position of the Global Growth Fund
in the security may be approximately the same as it would have been with a sin-
gle segment manager and no such sale and purchase. The Manager will consider
these costs in determining the allocation and reallocation of assets. Where
possible, in these instances, the Manager will seek to avoid transaction costs.

U.S. Equity segment The U.S. Equity segment manager emphasizes individual secu-
rity selection while diversifying across industries, which may help to reduce
risk. The U.S. Equity segment manager focuses primarily, but not exclusively,
on companies that have passed their "start-up" phase and show positive earnings
and the prospect of achieving significant profits beginning in the two to three
years after this acquisition of their stocks. When evaluating an individual
stock, the U.S. Equity segment manager considers whether the company may bene-
fit from:

 . new technologies, products or services
 . new cost reducing measures
 . changes in management
 . favorable changes in government regulations

                                                       Smith Barney Mutual Funds

                                                                              11
<PAGE>


International Equity segment The International Equity segment manager empha-
sizes individual security selection while diversifying across regions and coun-
tries which can help to reduce risk. While the International Equity segment
manager selects investments primarily for their capital appreciation potential,
some investments have an income component as well. Companies may have large-,
mid- or small-size market capitalizations and may operate in any market sector.
Market conditions around the world change constantly as does the location of
potential investment opportunities. Depending on the International Equity seg-
ment manager's assessment of overseas potential for long-term growth, this seg-
ment's emphasis among foreign markets (including emerging markets) and types of
issuers may vary.

In selecting individual companies for investment, the International Equity seg-
ment manager looks for the following:

 . Above average earnings growth
 . High relative return on invested capital
 . Experienced and effective management
 . Effective research, product development and marketing
 . Competitive advantages
 . Strong financial condition or stable or improving credit quality

By spreading the International Equity segment of the Global Growth Fund's
investments across many international markets, the International Equity segment
manager seeks to reduce volatility compared to an investment in a single
region. Unlike global mutual funds which may allocate a substantial segment of
assets to the U.S. markets, this segment of the Global Growth Fund invests sub-
stantially all of its assets in countries outside of the U.S.

In allocating assets among countries and regions, the economic and political
factors the segment manager evaluates include:

 . Low or decelerating inflation which creates a favorable environment for secu-
  rities markets
 . Stable governments with policies that encourage economic growth, equity
  investment and development of securities markets
 . Currency stability
 . The range of individual investment opportunities

Principal risks of investing in the Global Growth Fund
Investors could lose money on their investments, if:

 . Stock prices decline generally
 . Small or medium capitalization companies fall out of favor with investors
 . The segment manager's judgment about the attractiveness, growth prospects or
  potential appreciation of a particular stock proves to be incorrect
 . A particular product or service developed by a company in which the Global
  Growth Fund invests is unsuccessful, the company does not meet earnings
  expectations or other events depress the value of the company's stock

Compared to mutual funds that focus only on large capitalization companies, the
Global Growth Fund's share price may be more volatile because it invests a sig-
nificant portion of its assets in small and medium capitalization companies.
Medium and small capitalization companies may have more limited product lines,
markets and financial resources than large capitalization companies. They may
have shorter operating histories and less mature businesses. While medium capi-
talization companies generally have more established businesses than small cap-
italization companies, the prices of medium capitalization company stocks tend
to be more volatile than the prices of large capitalization company stocks. In
addition, small capitalization company stocks may be less liquid than large
capitalization company stocks.

Investing in foreign securities can bring added benefits, but it may also
involve additional risks. Investors could lose money on their investment if:

 . Foreign securities prices decline
 . Adverse governmental action or political, economic or market instability
  affects a foreign country or region
 . The currency in which a security is priced declines in value relative to the
  U.S. dollar
 . The segment manager's judgment about the attractiveness, value or potential
  appreciation of a particular security proves to be incorrect

Who may want to invest The Global Growth Fund may be an appropriate investment
if you:

 . Are seeking to participate in the long-term growth potential of small and

Performance
Because Global Growth Fund was added as a series to Smith Barney Investment
Funds Inc. this year, Global Growth Fund does not yet have a sufficient operat-
ing history to generate the performance information which other Smith Barney
funds show in bar and table form in this location of the prospectus.

 More on the Global Growth Fund's investments

International Equity segment
Currency transactions The Global Growth Fund may enter into transactions to buy
or sell currencies at a future date, which may be a few days or a number of
months. The Global Growth Fund may enter into these forward currency contracts
to:

 . Settle transactions in securities quoted in foreign currencies

 . Attempt to protect against the economic impact of adverse changes in the
  value of the U.S. dollar
 . Hedge currencies

The Global Growth Fund may not fully benefit from or may lose money on forward
currency transactions if changes in currency rates do not occur as anticipated
or do not correspond accurately to changes in the value of the Global Growth
Fund's holdings.

Debt securities This segment may invest up to 20% of its assets in debt securi-
ties of foreign corporate and governmental issuers as well as U.S. Government
securities and money market obligations of U.S. issuers. The Global Growth Fund
may invest in all types of debt securities of any maturity or credit quality.
These securities may be denominated in U.S. dollars or other currencies and may
pay fixed or variable rates of interest. The value of debt securities will go
down if interest rates go up, or the credit rating of the security is down-
graded or the issuer defaults on its obligation to pay principal or interest.
These risks are greater for debt securities rated below investment grade.

Both segments
Derivatives and hedging techniques The Global Growth Fund may, but need not,
use derivative contracts, such as futures and options on securities, securities
indices or currencies; options on these futures; forward currency contracts;
and interest rate or currency swaps for any of the following purposes:

 . To hedge against the economic impact of adverse changes in the market value
  of its securities, because of changes in stock market prices, currency
  exchange rates or interest rates

 . As a substitute for buying or selling securities

A derivative contract will obligate or entitle the Global Growth Fund to
deliver or receive an asset or cash payment based on the change in value of

Premier Selections Funds

16
<PAGE>

one or more securities, currencies or indices. Even a small investment in
derivative contracts can have a big impact on the Global Growth Fund's stock
market, currency and interest rate exposure. Therefore, using derivatives can
disproportionately increase losses and reduce opportunities for gains when
stock prices, currency rates or interest rates are changing. The Global Growth
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 Global
Growth Fund's holdings.

Defensive investing The Global Growth Fund may depart from its principal
investment strategies in response to adverse market, economic or political con-
ditions by taking temporary defensive positions in money market and short-term
debt securities or cash. If the Global Growth Fund takes a temporary defensive
position, it may be unable to achieve its investment goal.

Master/feeder option The Global Growth Fund may in the future seek to achieve
its investment objective by investing all of its net assets in another invest-
ment company having the same investment objective and substantially the same
investment policies and restrictions as those applicable to the Global Growth
Fund.

Premier Selections Large Cap  Fund

 Investments, risks and performance

The Premier Selections Large Cap Fund is made up of Growth and Value segments
(collectively the "Large Cap Fund").

Investment objective

Long-term capital growth.

Principal investment strategies
Key investments The Large Cap Fund invests primarily in companies with large
market capitalizations--those with total market capitalizations of $5 billion
or more at the time of investment. The Large Cap Fund's holdings will be com-
prised of stocks of approximately 40 companies.

Selection process The Large Cap Fund's strategy is to combine the efforts of
two segment managers with different styles (Value and Growth) and to invest in
the stock selections considered most attractive in the opinion of each segment
manager. Each segment manager builds a portfolio of stocks which he or she
believes will offer superior long-term capital growth potential. Each segment
manager may select up to 20 stocks. In connection with the execution of
purchases and sales, each segment may hold temporarily more or fewer than 20
securities. The size of the Large Cap Fund's position in any particular
security will be determined by the Manager based on the recommendation of the
segment managers.

In order to maintain an approximately equal division of all of the Large Cap
Fund's assets between the two segment managers, the Manager will:
 . Divide all daily cash inflows (purchases and reinvested distributions) and
  outflows (redemptions and expense items) between the two segment managers, as
  appropriate
 . Rebalance the allocation of Value and Growth segment securities in the Large
  Cap Fund's portfolio at any time in which the percentage of the Large Cap
  Fund's portfolio invested in either the Value or Growth segment's securities
  equals or exceeds 55% of the Large Cap Fund's total assets invested in both
  Value and Growth segment securities for a period of more than 10 days

Premier Selections Funds

18
<PAGE>


As a consequence of the rebalancing of assets described above, the Manager will
reallocate assets from the better performing segment to the other.
Reallocations may result in early recognition of taxable gains and in addi-
tional transaction costs to the extent that the sales of securities as part of
these reallocations result in higher portfolio turnover. In addition, if one
segment manager buys a security during a time frame when the other segment man-
ager sells it, the net position of the fund in the security may be approxi-
mately the same as it would have been with a single segment manager and no such
sale and purchase. The Manager will consider these costs in determining the
allocation and reallocation of assets. Where possible, in these instances, the
Manager will seek to avoid transaction costs.

Growth segment The segment manager emphasizes individual security selection.
The segment manager attempts to identify established large capitalization com-
panies with the highest growth potential. The segment manager then analyzes
each company in detail, focusing on its management, strategy and competitive
market position. Finally, the segment manager attempts to identify the most
attractively priced securities among the growth companies identified.

In selecting individual companies for investment, the segment manager consid-
ers:

 . Above average growth prospects
 . Technological innovation
 . Industry dominance
 . Competitive products and services
 . Global scope
 . Long term operating history
 . Strong cash flow
 . High return on equity
 . Strong financial condition
 . Experienced and effective management

Value segment The segment manager employs a two-step stock selection process in
the search for undervalued stocks of established, well recognized but temporar-
ily out of favor companies. First, the segment manager uses proprietary models
and fundamental research to identify stocks that are underpriced in the market
relative to their estimated value. Next, the segment manager looks for a posi-
tive catalyst in the company's near term outlook which the segment manager
believes will accelerate earnings and positively change the market's view of
the company's prospects.

                                                                              19
<PAGE>


In selecting individual companies for investment, the segment manager consid-
ers:

 . demonstrated financial strength
 . improving returns on invested capital and cash flow
 . new management
 . new product development or change in competitive position

 . regulatory changes favoring the company
 . restructuring

 . new business strategy not yet recognized by the marketplace

Principal risks of investing in the Large Cap Fund
Investors could lose money on their investments in the fund, or the fund may
not perform as well as other investments, if:

 . U.S. stock markets go down, or perform poorly relative to other types of
  investments
 . An adverse company specific event, such as an unfavorable earnings report,
  negatively affects the stock price of a company in which the Large Cap Fund
  invests
 . Large capitalization stocks fall out of favor with investors
 . The segment manager's judgment about the attractiveness, growth prospects or
  potential appreciation of a particular stock proves to be incorrect
 . One segment (Value or Growth) underperforms for an extended period

The Large Cap Fund is non-diversified, which means that the Large Cap Fund may
invest more than 5% of its assets in the securities of any one issuer. Invest-
ing in a non-diversified fund, particularly a fund which may invest in the
securities of only approximately 40 companies, may entail greater risk than is
normally associated with more widely diversified funds.

Who may want to invest The Large Cap Fund may be an appropriate investment if
you:

 . Are seeking to participate in the long-term growth potential of the U.S.
  stock market
 . Are looking for an investment with potentially greater return but higher risk
  than fixed income investments
 . Are willing to accept the risks of the stock market
 . Wish to invest indirectly in selected large capitalization companies

ating history to generate the performance information which other Smith Barney

 More on the Large Cap Fund's investments

Other investments While the Large Cap Fund intends to be substantially fully
invested in equity securities of large capitalization companies, the Large Cap
Fund may invest a portion of its assets in equity securities of companies with
total market capitalizations below $5 billion and in money market instruments
and/or cash to pay expenses and meet redemption requests.

The Large Cap Fund may also invest up to 10% of its assets (at the time of
investment) in foreign securities. The Large Cap Fund may invest directly in
foreign issuers or invest in depositary receipts. The Large Cap Fund's invest-
ments in foreign securities may involve greater risk than investments in secu-
rities of U.S. issuers. Because the value of a depositary receipt is dependent
upon the market price of an underlying foreign security, depositary receipts
are subject to most of the risks associated with investing in foreign securi-
ties directly. Foreign countries generally have markets that are less liquid
and more volatile than markets in the U.S. In some foreign countries, less
information is available about foreign issuers and markets because of less rig-
orous accounting and regulatory standards than in the U.S. Currency fluctua-
tions could erase investment gains or add to investment losses.

Defensive investing The Large Cap Fund may depart from its principal investment
strategies in response to adverse market, economic or political conditions by
taking temporary defensive positions in money market and short-term debt secu-
rities or cash. If the Large Cap Fund takes a temporary defensive position, it
may be unable to achieve its investment goal.

Master/feeder option The Large Cap Fund may in the future seek to achieve its
investment objective by investing all of its net assets in another investment
company having the same investment objective and substantially the same invest-
ment policies and restrictions as those applicable to the Large Cap Fund.

Frances A. Root, CFA, investment officer of the Manager and managing director
of Salomon Smith Barney, is the segment manager responsible for the day-to-day
management of the Large Cap Fund's Value segment. Ms. Root has 19 years of
securities business experience.

The Manager will monitor each fund's investments to ensure that each fund
complies with its investment policies. The Manager will rebalance the alloca-
tion of securities in the All Cap Growth and Global Growth Fund's portfolio,
respectively, at any time in which the percentage of each fund's portfolio
invested in a segment's securities deviates by at least 10% from a segment's
target allocation for a period of more than 10 days. The Manager will rebalance
the Large Cap Fund's allocation of securities at any time in which the percent-
age of the fund's portfolio invested in either value or growth segments securi-
ties equal or exceeds 55% of the fund's total assets invested in both the Value
and Growth securities for a period of more than 10 days. The Manager will also
monitor each fund's portfolio to ensure that no more than 25% of the fund's
assets are concentrated in the securities of companies in the same industry.

Management fees The Manager will be paid advisory fees equal to 0.75% of the

Growth Fund's average daily net assets and equal to 0.75% of Large Cap Fund's
average daily net assets.

Distribution plan Each fund has adopted a Rule 12b-1 distribution plan for its
Class A, B and L shares. Under the plan, each fund pays distribution and/or
service fees. These fees are an ongoing expense and, over time, may cost you
more than other types of sales charges.

In addition, the distributor may make payments for distribution and/or share-
holder servicing activities out of its past profits and other available sourc-
es. The distributor may also make payments for marketing, promotional or
related expenses to dealers. The amount of these payments is determined by the
distributor and may be substantial. The Manager or an affiliate may make simi-
lar payments under similar arrangements.

Transfer agent and shareholder servicing agent Citi Fiduciary Trust Company
serves as each fund's transfer agent and shareholder servicing agent (the
"transfer agent"). The transfer agent has entered into sub-transfer agency and
services agreements with PFPC Global Fund Services and PFS Shareholder Services
to serve as the fund's sub-transfer agents (the "sub-transfer agents") The sub-
transfer agents will perform certain functions including shareholder record
keeping and accounting services.

 Choosing a class of shares to buy

You can choose among four classes of shares: Classes A, B, L and Y. Each class
has different sales charges and expenses, allowing you to choose the class that
best meets your needs. Which class is more beneficial to you depends on the
amount and intended length of the investment.

 . If you plan to invest regularly or in large amounts, buying Class A shares
  may help you reduce sales charges and ongoing expenses

 . For Class B shares, all of your purchase amount and, for Class L shares, more
  of your purchase amount (compared to Class A shares) will be immediately
  invested. This may help offset the higher expenses of Class B and Class L
  shares, but only if a fund performs well

 . Class L shares have a shorter deferred sales charge period than Class B
  shares. However, because Class B shares convert to Class A shares, and Class
  L shares do not, Class B shares may be more attractive to long-term investors

You may buy shares from:

 . A broker-dealer, financial intermediary, financial institution or a
  distributor's financial consultants (each called a "Service Agent")
 . A fund, but only if you are investing through certain qualified plans or
  Service Agents

All Classes of shares are not available through all Service Agents. You should
contact your Service Agent for further information.

Investment minimums Minimum initial and additional investment amounts vary
depending on the class of shares you buy and the nature of your investment
account.

 Sales charges

Class A shares
You buy Class A shares at the offering price, which is the net asset value plus
a sales charge. You pay a lower sales charge as the size of your investment
increases to certain levels called breakpoints. You do not pay a sales charge
on each fund's distributions or dividends you reinvest in additional Class A
shares.

The table below shows the rate of sales charge you pay, depending on the amount
you purchase.

The table below also shows the amount of broker/dealer compensation that is
paid out of the sales charge. This compensation includes commissions and other
fees which Service Agents that sell shares of a fund receive. The distributors
keep up to approximately 10% of the sales charges imposed on Class A shares.
Service Agents also will receive the service fee payable on Class A shares at
an annual rate equal to 0.25% of the average daily net assets represented by
the Class A shares serviced by them.

Investments of $1,000,000 or more You do not pay an initial sales charge when
you buy $1,000,000 or more of Class A shares. However, if you redeem these
Class A shares within one year of purchase, you will pay a deferred sales
charge of 1.00%.

Qualifying for a reduced Class A sales charge There are several ways you can
combine multiple purchases of Class A shares of Smith Barney funds to take
advantage of the breakpoints in the sales charge schedule.

 . Accumulation privilege - lets you combine the current value of Class A shares
  owned

 . by you, or
 . by members of your immediate family

 and for which a sales charge was paid, with the amount of your next purchase
 of Class A shares for purposes of calculating the initial sales charge. Cer-
 tain trustees and fiduciaries may be entitled to combine accounts in deter-
 mining their sales charge.

 . Letter of intent - lets you purchase Class A shares of the funds and other
  Smith Barney funds over a 13-month period and pay the same sales charge, if
  any, as if all shares had been purchased at once. You may include purchases
  on which you paid a sales charge made within 90 days before you sign the let-
  ter.

Waivers for certain Class A investors Class A initial sales charges are waived
for certain types of investors, including:

 . Employees of NASD members
 . Investors participating in a fee-based program sponsored by certain broker-
  dealers affiliated with Citigroup
 . Investors who redeemed Class A shares of a Smith Barney fund in the past 60
  days, if the investor's Service Agent is notified

1f you want to learn about additional waivers of Class A initial sales charges,
contact your Service Agent or consult the Statement of Additional Information
("SAI").

Class B shares
You buy Class B shares at net asset value without paying an initial sales
charge. However, if you redeem your Class B shares within six years of pur-
chase, you will pay a deferred sales charge. The deferred sales charge
decreases as the number of years since your purchase increases.

Service Agents selling Class B shares receive a commission of up to 4.50% of
the purchase price of the Class B shares they sell. Service Agents also receive
a service fee at an annual rate equal to 0.25% of the average daily net assets
represented by the Class B shares they are servicing.

Class B conversion After 8 years, Class B shares automatically convert into
Class A shares. This helps you because Class A shares have lower annual
expenses. Your Class B shares will convert to Class A shares as follows:

Class L shares (available through certain Service Agents)
You buy Class L shares at the offering price, which is the net asset value plus
a sales charge of 1.00% (1.01% of the net amount invested). In addition, if you
redeem your Class L shares within one year of purchase, you will pay a deferred
sales charge of 1.00%. If you held Class C shares of the fund and/or other
Smith Barney funds on June 12, 1998 you will not pay an initial sales charge on
Class L shares you buy before June 22, 2001.

Service Agents selling Class L shares receive a commission of up to 2.00% of
the purchase price of the Class L shares they sell. Starting in the thirteenth
month, Service Agents also receive an annual fee of up to 1.00% of the average
daily net assets represented by the Class L shares held by their clients.

Class Y shares (available through certain Service Agents)
You buy Class Y shares at net asset value with no initial sales charge and no
deferred sales charge when you redeem. You must meet the $15,000,000 initial
investment requirement. You can use a letter of intent to meet this requirement
by buying Class Y shares of a fund over a 13-month period. To qualify, you must
initially invest $5,000,000.

 More about deferred sales charges

The deferred sales charge is based on the net asset value at the time of pur-
chase or redemption, whichever is less, and therefore, you do not pay a sales
charge on amounts representing appreciation or depreciation.

In addition, you do not pay a deferred sales charge on:

 . Shares exchanged for shares of another Smith Barney fund
 . Shares representing reinvested distributions and dividends
 . Shares no longer subject to the deferred sales charge

Each time you place a request to redeem shares, a fund will first redeem any
shares in your account that are not subject to a deferred sales charge and then
the shares in your account that have been held the longest.

If you redeemed shares of a Smith Barney fund in the past 60 days and paid a
deferred sales charge, you may buy shares of a fund at the current net asset
value and be credited with the amount of the deferred sales charge, if you
notify your Service Agent.

The fund's distributor receives deferred sales charges as partial compensation
for its expenses in selling shares, including the payment of compensation to
your Service Agent.

Deferred sales charge waivers
The deferred sales charge for each share class will generally be waived:

 . On payments made through certain systematic withdrawal plans
 . On certain distributions from a retirement plan
 . For involuntary redemptions of small account balances
 . For 12 months following the death or disability of a shareholder

If you want to learn more about additional waivers of deferred sales charges,
contact your Service Agent or consult the SAI.

                 If you do not have a brokerage account, contact your Service
                 Agent or write to a sub-transfer agent at the address on the
                 following page.

 Redeeming shares

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

                 If you hold share certificates, the sub-transfer agent must
                 receive the certificates endorsed for transfer or with signed
                 stock powers before the redemption is effective.

                 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.

                 rize telephone redemptions. If eligible, you may request
                 redemptions by telephone on any day the New York Stock

                 Requests received after the close of regular trading on the
                 Exchange are priced at the net asset value next determined.

                 Your redemption proceeds can be sent by check to your address
                 of record or by wire or electronic transfer (ACH) to a bank
                 account designated on your authorization form. You must sub-

                 ignated to receive wire or electronic transfers and you may
                 be asked to provide certain other documents. The sub-transfer
                 agent may charge a fee on an electronic transfer (ACH).

     Automatic   You can arrange for the automatic redemption of a portion of
          cash   your shares on a monthly or quarterly basis. To qualify you
    withdrawal   must own shares of a fund with a value of at least $10,000
         plans   ($5,000 for retirement plan accounts) and each automatic
                 redemption must be at least $50. If your shares are subject
                 to a deferred sales charge, the sales charge will be waived
                 if your automatic payments do not exceed 1% per month of the
                 value of your shares subject to a deferred sales charge.

                 The following conditions apply:

                 . Your shares must not be represented by certificates
                 . All dividends and distributions must be reinvested

                 the SAI.

 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, 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 of shares

 . Are sending signed share certificates or stock powers to a sub-transfer agent

 . Instruct a sub-transfer agent to mail the check to an address different from
  the one on your account
 . Changed your account registration

 . Changed your address within 45 days or less of your redemption request
 . 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

Premier Selections Funds

<PAGE>

 . 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 the applicable minimum investment amounts. If you choose not to
do so within 60 days, the fund may close your account and send you the redemp-
tion proceeds.

Excessive exchange transactions The Manager may determine that a pattern of
frequent exchanges is detrimental to a fund's performance and other sharehold-
ers. If so, a fund may limit additional purchases and/or exchanges by the
shareholder.

Share certificates The funds do not issue share certificates unless a written
request signed by all registered owners is made to a sub-transfer agent. If you
hold share certificates it will take longer to exchange or redeem shares.

 Dividends, distributions and taxes

Dividends Each fund generally pays dividends and makes capital gain distribu-
tions, if any, once a year, typically in December. Each fund may pay additional
distributions and dividends at other times if necessary for the fund to avoid a
federal tax. Capital gain distributions and dividends are reinvested in addi-
tional fund shares of the same class you hold. Each fund expects distributions
to be primarily from capital gain. You do not pay a sales charge on reinvested
distributions or dividends. Alternatively, you can instruct your Service Agent,
the transfer agent, or a sub-transfer agent, to have your distributions and/or
dividends paid in cash. You can change your choice at any time to be effective
as of the next distribution or dividend, except that any change given to the
transfer agent less than five days before the payment date will not be effec-
tive until the next distribution or dividend is paid.

Taxes In general, redeeming shares, exchanging shares and receiving distribu-
tions (whether in cash or additional shares) are all taxable events.

                                       shares owned more than

Long-term capital gain distributions are taxable to you as long-term capital
gain regardless of how long you have owned your shares. You may want to avoid
buying shares when a fund is about to declare a capital gain distribution or a
dividend, because it will be taxable to you even though it may actually be a
return of a portion of your investment.

After the end of each year, each fund will provide you with information about
the distributions and dividends you received and any redemptions of shares dur-
ing the previous year. If you do not provide the funds with your correct tax-
payer identification number and any required certifications, you may be subject
to back-up withholding of 31% of your distributions, dividends, and redemption
proceeds. Because each shareholder's circumstances are different and special
tax rules may apply, you should consult your tax adviser about your investment
in a fund.

 Share price

You may buy, exchange or redeem shares at their net asset value, plus any
applicable sales charge, next determined after receipt of your request in good
order. Each fund's net asset value is the value of its assets minus its liabil-
ities. 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. The Exchange is closed on certain holidays listed in the SAI. This calcu-
lation is done when regular trading closes on the Exchange (normally 4 p.m.
Eastern time).

Each fund generally values its portfolio securities based on market prices or
quotations. A fund's currency conversions are done when the London Stock
Exchange closes which is 12 noon Eastern time. 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 value. Fair value is determined in accor-
dance with procedures approved by a fund's board. A 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 New York Stock 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 orders to buy, exchange or redeem shares to a
fund's sub-transfer agent before the sub-transfer 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 audi-
tors, whose report, along with the fund's financial statements, is included in
the annual report (available upon request). No information is presented for
Class Y shares of Large Cap Fund because no Class Y shares were outstanding for
the period shown. No information is presented for Classes A, B, L or Y of All
Cap Growth Fund and Global Growth Fund because these funds have not been in
existence for a year.
