PRINCIPAL-PROTECTED
TRUST CERTIFICATES

LINKED TO THE DOW JONES INDUSTRIAL AVERAGE(SM) AND THE NIKKEI 225 STOCK
AVERAGE(SM)
DUE                  , 2010

This offering summary represents a summary of the terms and conditions of the
certificates. We encourage you to read the preliminary prospectus and pricing
supplement related to this offering. Capitalized terms used in this summary are
defined in "Preliminary Terms" on page 4 of this offering summary.

Overview of the Trust Certificates
The Principal-Protected Trust Certificates Linked to the Dow Jones Industrial
Average(SM) and the Nikkei 225 Stock Average(SM) due           , 2010 are
equity-linked preferred securities issued by Safety First Trust Series 2006-1
that have a maturity of approximately 3.50 to 3.65 years. Some key
characteristics of the Certificates include:

- -   Principal Protection like a Fixed-Income Investment.  Similar to a fixed
    income investment, an investor's initial investment is 100% principal
    protected if the investor holds the Certificates to maturity.

- -   No Periodic Payments.  The Certificates do not offer current income, which
    means that investors do not receive any periodic interest or other payments
    on the Certificates prior to maturity. Instead of a periodic fixed or
    floating rate of interest, return on the Certificates is paid at maturity
    and is based upon the appreciation, if any, of the values of the Dow Jones
    Industrial Average and the Nikkei 225 Stock Average. In addition, you will
    not receive any dividend payments or other distributions, if any, on the
    stocks included in the indices.

- -   Equity Market Participation.  If you hold the Certificates to maturity, you
    will be entitled to receive (i) $10 (your initial investment), plus (ii) a
    supplemental distribution amount, which may be positive or zero, based on
    the appreciation, if any, of the value of the Underlying Basket.

- -   Citigroup Guarantee of Trust Assets.  The payments under the Certificates
    will be made to the extent that Citigroup Funding makes payments under the
    Securities and Warrants, the assets of the Trust. Payment obligations of
    Citigroup Funding under the Securities and Warrants are guaranteed by its
    parent company Citigroup Inc.

- -   No Interim Income Recognition; Short-Term Capital Gain or Loss.  U.S.
    investors who make a "mixed straddle" election should not be required to
    recognize income or gain until maturity or sale of the Certificates. Upon
    maturity or sale of the Certificates, investors should recognize short-term
    capital gain or loss, regardless of how long they have held the
    Certificates. U.S. investors can make the mixed straddle election by
    complying with the identification requirements described in the preliminary
    prospectus and pricing supplement related to this offering and by filing IRS
    form 6781 attached to it.

Beginning on the date the Certificates are issued and ending on the date that is
one business day prior to the Valuation Date, you will have the right to
exchange each Certificate you hold for a pro rata portion of the assets of the
Trust, which consist of the Securities and Warrants issued by Citigroup Funding
Inc., upon proper notice to the trustee. You cannot recognize long-term capital
gain from your investment in the Certificates unless you exercise your Exchange
Right, then dispose of either the Securities or the Warrants, and then hold the
remaining instrument for more than one year after that disposition.

Neither the Securities nor the Warrants are principal protected. You should be
aware that if you choose to exercise your Exchange Right and hold only the
Securities or only the Warrants, you will lose the benefit of principal
protection at maturity and may receive substantially less than the amount of
your initial investment in the Certificates.

In order to exercise your Exchange Right, your account must be approved for
options trading. You should consult with your financial advisor to determine
whether your account would meet the options trading requirements.

Types of Investors
The Certificates are hybrid investments that combine characteristics of equity
and fixed income instruments. They may be an attractive investment for an
investor seeking growth potential on a principal protected basis and willing to
forego current income. This type of investor may include, but is not limited to:

- -   Fixed-income investors currently invested in zero coupon bonds who are
    seeking an opportunity to earn potentially higher equity-linked returns.

- -   Conservative equity investors who wish to participate in the upside
    potential of broad-based equity market indices, while limiting their
    exposure to the downside.

- -   Investors who can hold the Certificates for approximately 3.50 to 3.65
    years.

                                date that is one business day prior to the Valuation Date,

                                the Trust (each Certificate is exchangeable into one

Key Benefits
- -   Growth Potential.  The Supplemental Distribution Amount payable at maturity
    is based on the Ending Value of the Underlying Basket on the Valuation Date,
    enabling you to participate in the potential increase in the value of the
    Underlying Basket during the term of the Certificates without directly
    investing in the indices comprising the Underlying Basket or having to
    acquire each of the component stocks of the indices.

- -   Capital Preservation.  At maturity, unless you have exercised your Exchange
    Right, we will pay you at least the principal amount of the Certificates
    regardless of the performance of the Underlying Basket.

- -   Diversification.  The Certificates are linked to the Dow Jones Industrial
    Average and the Nikkei 225 Stock Average and may allow you to diversify an
    existing portfolio mix of stocks, bonds, mutual funds and cash.

- -   No Interim Income Recognition.  If you make the tax elections as described
    in detail in the preliminary prospectus and pricing supplement related to
    this offering, you should not be required to accrue income or to take into
    account any gain or loss with respect to the Certificates until maturity or
    disposition of the Certificates.

Key Risks
An investment in the Certificates, Securities and Warrants involves significant
risks. While some of the risk considerations are summarized below, please review
the "Risk Factors" section of the preliminary prospectus and pricing supplement
related to this offering for a full description of risks.

- -   Possibility of No Appreciation.  If the Ending Value, which will be the
    closing value of the Underlying Basket on the Valuation Date, is equal to or
    less than the Starting Value, the payment you receive at maturity will be
    limited to the amount of your initial investment in the Certificates, even
    if the closing value of the Underlying Basket is greater than the Starting
    Value at one or more times during the term of the Certificates or if the
    closing value of the Underlying Basket at maturity exceeds the Starting
    Value. In addition, neither the Securities nor the Warrants are principal
    protected. Thus, if you choose to exercise your Exchange Right and do not
    hold both the Securities and the Warrants to maturity, you could receive
    substantially less than the amount of your initial investment in the
    Certificates.

- -   No Periodic Payments.  You will not receive any periodic payments of
    interest or any other periodic payments on the Certificates. In addition,
    you will not be entitled to receive dividend payments or other
    distributions, if any, made on the stocks included in the indices comprising
    the Underlying Basket.

- -   Potential for a Lower Comparable Yield.  The Certificates do not pay any
    periodic interest. As a result, even if the Ending Value is greater than the
    Starting Value, the effective yield on the Certificates may be less than
    that which would be payable on a conventional fixed-rate debt security of
    Citigroup Funding of comparable maturity.

- -   Secondary Market May Not Be Liquid.  Citigroup Funding will apply to list
    the Certificates on the American Stock Exchange, but the secondary market
    may not be liquid and may not continue for the term of the Certificates. In
    addition, neither the Securities nor the Warrants will be listed on any
    exchange. Although Citigroup Global Markets intends to make a market in the
    Certificates, Securities and Warrants, it is not obligated to do so.

- -   Resale Value of the Certificates May Be Lower Than Your Initial
    Investment.  Due to, among other things, changes in the price of and
    dividend yields on the stocks included in the indices comprising the
    Underlying Basket, interest rates, the earnings performance of the issuers
    of the stocks included in the indices, other economic conditions and
    Citigroup Funding

    and Citigroup's perceived creditworthiness, the Certificates may trade at
    prices below their initial issue price of $10 per certificate. You could
    receive substantially less than the amount of your initial investment if you
    sell your Certificates prior to maturity.

- -   Fees and Conflicts.  Citigroup Global Markets Inc. and its affiliates
    involved in this offering are expected to receive compensation for
    activities and services provided in connection with the Certificates.
    Further, Citigroup Funding expects to hedge its obligations under the
    Certificates through the trading of the stocks included in the indices
    comprising the Underlying Basket or other instruments, such as options,
    swaps or futures, based upon the Underlying Basket, the indices comprising
    the Underlying Basket or the stocks included in the indices by one or more
    of its affiliates. Each of Citigroup Funding's or its affiliates' hedging
    activities and Citigroup Global Market's role as the Calculation Agent for
    the Certificates may result in a conflict of interest.

- -   Citigroup Credit Risk.  The Certificates are subject to the credit risk of
    Citigroup, Citigroup Funding's parent company and the guarantor of the
    payments due on the Certificates.

- -   Neither the Securities nor the Warrants are Principal-Protected
    Individually.  If you exercise your Exchange Right, you will receive a pro
    rata portion of the assets of the Trust, which consist of the Securities and
    the Warrants. In order to exercise your Exchange Right, your account must be
    approved for options trading. You should consult with your financial advisor
    to determine whether your account would meet the options trading
    requirements. Neither the Securities nor the Warrants are principal
    protected. Thus, if you choose to exercise your Exchange Right and hold only
    the Securities or only the Warrants, you will lose the benefit of principal
    protection at maturity and could receive substantially less than the amount
    of your initial investment. If you hold only the Securities, your investment
    may result in a loss if the Ending Value is less than the Starting Value. If
    you hold only the Warrants, the payment on the Warrants will be zero unless
    the Ending Value is less than the Starting Value. These additional risks
    also include that the Securities and the Warrants may trade at prices
    substantially below their initial purchase prices.

- -   Additional Risks Upon Exchange If You Hold Only the Securities or Only the
    Warrants.  If you exercise your Exchange Right and hold only the Securities
    or only the Warrants, you will be subject to other risks in addition to the
    loss of principal protection at maturity. These additional risks include, in
    the case of the Securities, that the Securities will participate fully in
    the depreciation of the Underlying Basket and, in the case of the Warrants,
    that the Warrants may lose substantially all their value due to relatively
    small increases in the value of the Underlying Basket, particularly
    increases above the Starting Value.

Certain U.S. Federal Income Tax Considerations
The following summarizes certain federal income tax considerations for U.S.
investors that purchase the Certificates at the initial offering and hold the
Certificates as capital assets. In general, a U.S. investor will be treated as
owning a pro rata share of the assets of the Trust. Under the treatment that
each holder will agree to with the Trust and Citigroup Funding, the Securities
and the Warrants will be treated as two separate financial instruments.

A U.S. holder's tax treatment may depend on the applicability of certain
elections. The Trust will make a "mixed straddle" election on behalf of all
holders of the Certificates by identifying on its records the Securities and the
Warrants as a mixed straddle and by filing IRS form 6781. The Trust also will
make an "identified straddle" election on behalf of all holders of the
Certificates by identifying on its records each Security and each Warrant as a
separate identified straddle. It is unclear, however, whether such elections
made by the Trust on behalf of a holder will be effective. Therefore, it is
generally advisable that U.S. investors


    EQUITY FIRST A FAMILY OF INTELLIGENT INVESTMENTS EQUITY

                                                    SAFETY FIRST(SM) INVESTMENTS
                                                                               7

also make a mixed straddle election and an identified straddle election by
complying with the identification requirements described in the preliminary
prospectus and pricing supplement and by filing IRS form 6781 (applicable to the
mixed straddle election) attached thereto. Assuming that the "mixed straddle"
election and the identified straddle election will apply, the Certificates will
be taxed as follows:

- -   A U.S. holder will not be required to accrue income or take into account
    gain with respect to Certificates until maturity or disposition.

- -   At maturity or upon a sale of all of U.S. holder's Certificates, such holder
    will recognize net capital gain or loss equal to the difference between the
    amount of cash received and the amount that U.S. holder paid for the
    Certificates. Such capital gain or loss will be short-term gain or loss
    regardless of how long the U.S. holder has held the Certificates.

- -   If a U.S. holder exchanges its Certificates for Securities and Warrants and
    disposes of one but not the other, such holder will have long-term capital
    gain or loss at maturity or on disposition of the Securities or the Warrants
    only if the U.S. holder has held the Securities or the Warrants for more
    than one year after the disposition of the other instrument, respectively.
    In order to exercise your Exchange Right, your account must be approved for
    options trading. You should consult with your financial advisor to determine
    whether your account would meet the options trading requirements. You should
    be aware, however, that if you hold only the Securities or only the
    Warrants, you will lose the benefit of principal protection at maturity.
    Losses realized on the disposition of the Securities or the Warrants may be
    required to be capitalized into the tax basis of the Warrants or the
    Securities (as the case may be) retained by the U.S. Holder.

No statutory, judicial or administrative authority addresses the
characterization of the Securities and the Warrants or similar instruments for
U.S. federal income tax purposes. As a result, significant aspects of the U.S.
federal income tax consequences of an investment in the Certificates are not
certain. ACCORDINGLY, A PROSPECTIVE INVESTOR (INCLUDING A TAX EXEMPT INVESTOR)
IN THE CERTIFICATES SHOULD CONSULT ITS OWN TAX ADVISOR IN DETERMINING THE TAX
CONSEQUENCES OF AN INVESTMENT IN THE CERTIFICATES.

In the case of a holder of the Certificates that is not a U.S. person, any gain
realized upon the sale, maturity, exchange or other taxable disposition of the
Certificates, the Securities or the Warrants generally will not be subject to
U.S. income or withholding tax provided that: (i) the holder complies with
applicable certification requirements (including in general the furnishing of an
IRS form W-8 or substitute form), (ii) in the case of an individual, such
individual is not present in the United States for 183 days or more in the

The Underlying Basket

General.  The Underlying Basket will be established on the Pricing Date and will
be calculated by the Calculation Agent. The Underlying Basket will represent the
values of two equity indices: the Dow Jones Industrial Average and the Nikkei
225 Stock Average. The Starting Value of the Underlying Basket will be set to
100 on the Pricing Date and each of the two indices comprising the Underlying
Basket will initially represent 50% of the value of the Underlying Basket. The
closing value of the Underlying Basket on any index business day will equal the
sum of the products of (i) the closing value on that day of each index
comprising the basket and (ii) a fixed factor (the "Multiplier") applicable to
each index. The Multiplier for each index will be determined on the Pricing Date
and will equal 50 divided by the closing value of the applicable index on the
Pricing Date.

The following graph sets forth the hypothetical historical closing values of the
Underlying Basket on each index business day from January 1, 1996 through
October 16, 2006, each calculated as if the Underlying Basket had been created
on January 1, 1996 with an initial value of 100. The Underlying Basket actually
will be established on the Pricing Date with a value of 100.

Actual historical closing values of each of the two component indices were used
to calculate the hypothetical historical closing values of the Underlying
Basket. However, these hypothetical historical closing values should not be
taken as an indication of the actual composition of the Underlying Basket on the
Pricing Date or the future performance of the Underlying Basket. Any
hypothetical historical upward or downward trend in the value of the Underlying
Basket during any period set forth below is not an indication that the
Underlying Basket is more or less likely to increase or decrease at any time
during the term of the Certificates.

Hypothetical Maturity Payment Examples
The examples of hypothetical maturity payments set forth below are intended to
illustrate the effect of different Ending Values on the amount payable on the
Certificates at maturity. All of the hypothetical examples are based on the
following assumptions:

<Table>
                                             
- -   Issue Price: $10.00                         -   Term of the Certificates: 3.65 years
- -   Starting Value: 100
- -   The Certificates are held to maturity and are not exchanged for the Securities and
the Warrants.
</Table>

As shown by the examples below, if the Basket Return is 0% or less, you will
receive an amount at maturity equal to $10.00 per certificate, the amount of
your initial investment in the Certificates. If the Basket Return is greater
than 0%, you will receive an amount at maturity that is greater than your
initial investment in the Certificates.

ERISA and IRA Purchase Considerations
Employee benefit plans subject to ERISA, entities the assets of which are deemed
to constitute the assets of such plans, governmental or other plans subject to
laws substantially similar to ERISA and retirement accounts (including Keogh,
SEP and SIMPLE plans, individual retirement accounts and individual retirement
annuities) are permitted to purchase the Certificates, the Securities and the
Warrants as long as either (A) (1) no Citigroup Global Market affiliate or
employee is a fiduciary to such plan or retirement account that has or exercises
any discretionary authority or control with respect to the assets of such plan
or retirement account used to purchase the Certificates, the Securities or the
Warrants or renders investment advice with respect to those assets, and (2) such
plan or retirement account is paying no more than adequate consideration for the
Certificates, the Securities or the Warrants or (B) its acquisition and holding
of the Certificates, the Securities or the Warrants is not prohibited by any
such provisions or laws or is exempt from any such prohibition.

However, individual retirement accounts, individual retirement annuities and
Keogh plans, as well as employee benefit plans that permit participants to
direct the investment of their accounts, will NOT be permitted to purchase or
hold the Certificates, the Securities or the Warrants if the account, plan or
annuity is for the benefit of an employee of Citigroup Global Markets or a
family member and the employee receives any compensation (such as, for example,
an addition to bonus) based on the purchase of the Certificates, the Securities
or the Warrants by the account, plan or annuity.

You should refer to the section "ERISA Matters" in the preliminary prospectus
and pricing supplement related to this offering for more information.

Additional Considerations
If the closing value of any of the indices comprising the Underlying Basket is
not available on the Valuation Date, the Calculation Agent may determine the
Ending Value in accordance with the procedures set forth in the preliminary
prospectus and pricing supplement related to this offering. In addition, if any
of the indices comprising the Underlying Basket is discontinued, the Calculation
Agent may determine the Ending Value by reference to a successor index or, if no
successor index is available, in accordance with the procedures last used to
calculate the relevant index prior to any such discontinuance. You should refer
to the sections "Description of the Certificates -- Supplemental Distribution
Amount" and "-- Discontinuance of an Index Comprising the Underlying Basket" in
the preliminary prospectus and pricing supplement for more information.

Citigroup Global Markets is an affiliate of the Trust and Citigroup Funding.
Accordingly, the offering will conform to the requirements set forth in Rule
2810 of the Conduct Rules of the National Association of Securities Dealers
regarding direct participation programs.

Client accounts over which Citigroup or its affiliates have investment
discretion are NOT permitted to purchase the Certificates, either directly or
indirectly.
