Exhibit 4.01


 


This Note is a Global
Security within the meaning of the Indenture hereinafter referred to and is registered in the name of the Depository named below
or a nominee of the Depository. This Note is not exchangeable for Notes registered in the name of a Person other than the Depository
or its nominee except in the limited circumstances described herein and in the Indenture, and no transfer of this Note (other than
a transfer of this Note as a whole by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository

Unless this certificate
is presented by an authorized representative of The Depository Trust Company, a New York corporation (the “Depository”),
to the Company or its agent for registration of transfer, exchange, or payment, and any certificate issued is registered in the
name of Cede & Co. or in such other name as is requested by an authorized representative of the Depository (and any payment
is made to Cede & Co. or to such other entity as is requested by an authorized representative of the Depository), ANY TRANSFER,
PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof, Cede
& Co., has an interest herein.

CITIGROUP INC., a
Delaware corporation (the “Company”, which term includes any successor Person under the Indenture), for value received,
hereby promises to pay to Cede & Co., or registered assigns, the principal sum of $500,000,000 on May 1, 2017 and to pay interest
thereon from and including May 1, 2014 or from the most recent Interest Payment Date to which interest has been paid or duly provided
for, quarterly, on the first day of each February, May, August, and November, commencing August 1, 2014, at the rate per annum
for each Interest Period of three-month LIBOR, determined as provided herein, plus 0.5200% until the principal hereof is paid or
made available for payment. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will,
as provided in the Indenture, be paid to the Person in whose name this Note is registered at the close of business on the Record
Date for such interest, which shall be the Business Day immediately preceding such Interest Payment Date.


 


Any such interest
not so punctually paid or duly provided for will forthwith cease to be payable to the holder on such Record Date and may either
be paid to the Person in whose name this Note is registered at the close of business on a subsequent Record Date, such subsequent
Record Date to be not less than ten days prior to the date of payment of such defaulted interest, notice whereof shall be given
to holders of Notes of this series not less than ten days prior to such subsequent Record Date, or be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange on which the Notes of this series may be listed,
and upon such notice as may be required by such exchange, all as more fully provided in the Indenture.


 






    	 



    	 



    

 


Interest hereon
will be calculated on the basis of the actual number of days elapsed in an Interest Period and a 360-day year. Dollar amounts resulting
from such calculation will be rounded to the nearest cent, with one-half cent being rounded upward. An “Interest Period”
shall be the period from and including an Interest Payment Date (or from May 1, 2014 in the case of the first Interest Payment
Date) to and including the day immediately preceding the next Interest Payment Date.


 


If an Interest
Payment Date falls on a day that is not a Business Day, such Interest Payment Date will be the next succeeding Business Day. If
the Maturity of the Notes falls on a day that is not a Business Day, the payment due on Maturity will be postponed to the next
succeeding Business Day, and no further interest will accrue in respect of such postponement. If a date for payment of interest
or principal on the Notes falls on a day that is not a business day in the place of payment, such payment will be made on the next
succeeding business day in such place of payment as if made on the date the payment was due. No interest will accrue on any amounts
payable for the period from and after the due date for payment of such principal or interest.


 


For these purposes,
“Business Day” means any day which is a day on which commercial banks settle payments and are open for general business
in The City of New York.


 


Payment of the principal
of and interest on this Note will be made at the office or agency of the Trustee maintained for that purpose in The City of New
York.


 


Reference is hereby
made to the further provisions of this Note set forth on the reverse hereof, which further provisions shall for all purposes have
the same effect as if set forth at this place.


 


Unless the certificate
of authentication hereon has been executed by the Trustee or by an authenticating agent on behalf of the Trustee by manual signature,
this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

This Note is one of
a duly authorized issue of Securities of the Company (the “Notes”), issued and to be issued in one or more series under
the Indenture, dated as of November 13, 2013 (as amended and supplemented from time to time, the “Indenture”), between
the Company and The Bank of New York Mellon, as Trustee (the “Trustee”, which term includes any successor trustee under
the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the holders of the Notes and of
the terms upon which the Notes are, and are to be, authenticated and delivered. This Note is one of the series designated on the
face hereof, initially limited in aggregate principal to $750,000,000.


 


This Note will bear
interest for each Interest Period at a rate determined by Citibank, N.A., acting as Calculation Agent. The interest rate on this
Note for a particular Interest Period will be a per annum rate equal to three-month LIBOR as determined on the related Interest
Determination Date, plus 0.5200%. The Interest Determination Date for an Interest Period will be the second London business day
preceding such Interest Period. The Interest Determination Date for the first Interest Period was July 29, 2014. Promptly upon
determination, the Calculation Agent will inform the Trustee and the Company of the interest rate for the next Interest Period.
Absent manifest error, the determination of the interest rate by the Calculation Agent shall be binding and conclusive on the holders
of Notes, the Trustee and the Company.


 


A London business day
is a day on which dealings in deposits in U.S. dollars are transacted in the London interbank market.


 


On any Interest Determination
Date, LIBOR will be equal to the offered rate for deposits in U.S. dollars having an index maturity of three months for the next
Interest Period, in amounts of at least $1,000,000, as such rate appears on Reuters Screen LIBOR01 at approximately 11:00 a.m.,
London time, on such Interest Determination Date. If the Reuters Screen LIBOR01 is replaced by another service or ceases to exist,
the Calculation Agent will use the replacing service or such other service that is selected to display the London interbank offered
rates for U.S. dollar deposits.


 


If no offered rate
appears on Reuters Screen LIBOR01 on an Interest Determination Date at approximately 11:00 a.m., London time, then the Calculation
Agent (after consultation with the Company) will select four major banks in the London interbank market and shall request each
of their principal London offices to provide a quotation of the rate at which three-month deposits in U.S. dollars in amounts of
at least $1,000,000 are offered by it to prime banks in the London interbank market, on that date and at that time, that is representative
of single transactions at that time. If at least two quotations are provided, LIBOR will be the arithmetic average of the quotations
provided. Otherwise, the Calculation Agent will select three major banks in New York City and shall request each of them to provide
a quotation of the rate offered by them at approximately 11:00 a.m., New York City time, on the Interest Determination Date for
loans in U.S. dollars to leading European banks having an index maturity of three months for the applicable Interest Period in
an amount of at least $1,000,000 that is representative of single transactions at that time. If three quotations are provided,
LIBOR will be the arithmetic average of the quotations provided. Otherwise, the rate of LIBOR for the next Interest Period will
be set equal to the rate of LIBOR for the current Interest Period.


 






    	5



    	 



    

 


Upon request from any
Noteholder, the Calculation Agent will provide the interest rate in effect on this Note for the current Interest Period and, if
it has been determined, the interest rate to be in effect for the next Interest Period.


 


If an event of default
(as defined in the Indenture) with respect to Notes of this series shall occur and be continuing, the principal of the Notes of
this series may be declared due and payable in the manner and with the effect provided in the Indenture.


 


Sections 12.02 and
12.03 of the Indenture containing provisions for defeasance apply to this Note. At any time the entire indebtedness of this Note
may be defeased upon compliance by the Company with certain conditions set forth in Section 12.04 of the Indenture.


 


The Indenture contains
provisions permitting the Company and the Trustee, without the consent of the holders of the Securities, to establish, among other
things, the form and terms of any series of Securities issuable thereunder by one or more supplemental indentures, and, with the
consent of the holders of a majority in aggregate principal amount of Securities at the time outstanding which are affected thereby,
to modify the Indenture or any supplemental indenture or the rights of the holders of Securities of such series to be affected,
provided that no such modification will (i) extend the fixed maturity of any Securities, reduce the rate or extend the time of
payment of interest thereon, reduce the principal amount thereof or the premium, if any, thereon, reduce the amount of the principal
of Original Issue Discount Securities payable on any date, change the currency in which Securities are payable, or impair the right
to institute suit for the enforcement of any such payment on or after the maturity thereof, without the consent of the holder of
each Security so affected, or (ii) reduce the aforesaid percentage of Securities of any series the consent of the holders of which
is required for any such modification without the consent of the holders of all Securities of such series then outstanding, or
(iii) modify the rights, duties or immunities of the Trustee unless the Trustee agrees to such modification.


 


No reference herein
to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and interest on this Note at the times, place and rate, and in the coin or
currency, herein prescribed.


 


This Note is a Global
Security registered in the name of a nominee of the Depository. This Note is exchangeable for Notes registered in the name of a
person other than the Depository or its nominee only in the limited circumstances hereinafter described. Unless and until it is
exchanged in whole or in part for definitive Notes in certificated form, this Note may not be transferred except as a whole by
the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository.

The Notes represented
by this Global Security are exchangeable for definitive Notes in certificated form of like tenor as such Notes in denominations
of $1,000 and whole multiples of $1,000 in excess thereof only if (i) the Depository notifies the Company that it is unwilling
or unable to continue as Depository for the Notes and the Company is unable to appoint a successor depository or (ii) the Depository
ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, or (iii) the Company in its sole
discretion decides to allow the Notes to be exchanged for definitive Notes in registered form. Any Notes that are exchangeable
pursuant to the preceding sentence are exchangeable for certificated Notes issuable in authorized denominations and registered
in such names as the Depository shall direct. As provided in the Indenture and subject to certain limitations therein set forth,
the transfer of definitive Notes in certificated form is registrable in the register maintained by the Company in The City of New
York for such purpose, upon surrender of the definitive Note for registration of transfer at the office or agency of the registrar,
duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the registrar duly
executed by, the holder thereof or his attorney duly authorized in writing, and thereupon one or more new Notes of this series
and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee
or transferees. Subject to the foregoing, this Note is not exchangeable, except for a Global Security or Global Securities of this
issue of the same principal amount to be registered in the name of the Depository or its nominee.


 


No service charge shall
be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.


 


Prior to due presentment
of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person
in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the
Company, the Trustee nor any such agent shall be affected by notice to the contrary.


 


The Company will pay
additional amounts (“Additional Amounts”) to the beneficial owner of any Note that is a non-United States person in
order to ensure that every net payment on such Note will not be less, due to payment of U.S. withholding tax, than the amount then
due and payable. For this purpose, a “net payment” on a Note means a payment by the Company or a paying agent, including
payment of principal and interest, after deduction for any present or future tax, assessment or other governmental charge of the
United States. These Additional Amounts will constitute additional interest on the Note.


 


The Company will not
be required to pay Additional Amounts, however, in any of the circumstances described in items (1) through (14) below.


 


		(1)	Additional Amounts will not be payable if a payment
on a Note is reduced as a result of any tax, assessment or other governmental charge that is imposed or withheld solely by reason
of the beneficial owner:



 


		(a)	having a relationship with the United States as a
citizen, resident or otherwise;



		(b)	having had such a relationship in the past or



		(c)	being considered as having had such a relationship.



 






    	7



    	 



    

 


		(2)	Additional Amounts will not be payable if a payment
on a Note is reduced as a result of any tax, assessment or other governmental charge that is imposed or withheld solely by reason
of the beneficial owner:



 


		(a)	being treated as present in or engaged in a trade
or business in the United States;



		(b)	being treated as having been present in or engaged
in a trade or business in the United States in the past or



		(c)	having or having had a permanent establishment in
the United States.



 


		(3)	Additional Amounts will not be payable if a payment
on a Note is reduced as a result of any tax, assessment or other governmental charge that is imposed or withheld in whole or in
part by reason of the beneficial owner being or having been any of the following (as such terms are defined in the Internal Revenue
Code of 1986, as amended):



 


		(a)	personal holding company;



		(b)	foreign private foundation or other foreign tax-exempt
organization;



		(c)	passive foreign investment company;



		(d)	controlled foreign corporation or



		(e)	corporation which has accumulated earnings to avoid
United States federal income tax.



 


		(4)	Additional Amounts will not be payable if a payment
on a Note is reduced as a result of any tax, assessment or other governmental charge that is imposed or withheld solely by reason
of the beneficial owner owning or having owned, actually or constructively, 10 percent or more of the total combined voting power
of all classes of stock of the Company entitled to vote or by reason of the beneficial owner being a bank that has invested in
a Note as an extension of credit in the ordinary course of its trade or business.



 


For purposes of items (1) through (4) above,
“beneficial owner” means a fiduciary, settlor, beneficiary, member or shareholder of the holder if the holder is an
estate, trust, partnership, limited liability company, corporation or other entity, or a person holding a power over an estate
or trust administered by a fiduciary holder.


 


		(5)	Additional Amounts will not be payable to any beneficial
owner of a Note that is a:



 


		(a)	fiduciary;



		(b)	partnership;



		(c)	limited liability company or



		(d)	other fiscally transparent entity



 


			or that is not the sole beneficial owner of the Note, or any portion of the Note. However, this
exception to the obligation to pay Additional Amounts will only apply to the extent that a beneficiary or settlor in relation to
the fiduciary, or a beneficial owner or member of the partnership, limited liability company or other fiscally transparent entity,
would not have been entitled to the payment of an Additional Amount had the beneficiary, settlor, beneficial owner or member received
directly its beneficial or distributive share of the payment.



 






    	8



    	 



    

 


		(6)	Additional Amounts will not be payable if a payment
on a Note is reduced as a result of any tax, assessment or other governmental charge that is imposed or withheld solely by reason
of the failure of the beneficial owner or any other person to comply with applicable certification, identification, documentation
or other information reporting requirements. This exception to the obligation to pay Additional Amounts will only apply if compliance
with such reporting requirements is required by statute or regulation of the United States or by an applicable income tax treaty
to which the United States is a party as a precondition to exemption from such tax, assessment or other governmental charge.



 


		(7)	Additional Amounts will not be payable if a payment
on a Note is reduced as a result of any tax, assessment or other governmental charge that is collected or imposed by any method
other than by withholding from a payment on a Note by the Company or a paying agent.



 


		(8)	Additional Amounts will not be payable if a payment
on a Note is reduced as a result of any tax, assessment or other governmental charge that is imposed or withheld by reason of
a change in law, regulation, or administrative or judicial interpretation that becomes effective more than 15 days after the payment
becomes due or is duly provided for, whichever occurs later.



 


		(9)	Additional Amounts will not be payable if a payment
on a Note is reduced as a result of any tax, assessment or other governmental charge that is imposed or withheld by reason of
the presentation by the beneficial owner of a Note for payment more than 30 days after the date on which such payment becomes
due or is duly provided for, whichever occurs later.



 


		(10)	Additional Amounts will not be payable if a payment
on a Note is reduced as a result of any:



 


		(a)	estate tax;



		(b)	inheritance tax;



		(c)	gift tax;



		(d)	sales tax;



		(e)	excise tax;



		(f)	transfer tax;



		(g)	wealth tax;



		(h)	personal property tax or



		(i)	any similar tax, assessment, withholding, deduction
or other governmental charge.



 






    	9



    	 



    

 


		(11)	Additional Amounts will not be payable if a payment
on a Note is reduced as a result of any tax, assessment, or other governmental charge required to be withheld by any paying agent
from a payment of principal or interest on a Note if such payment can be made without such withholding by any other paying agent.



 


		(12)	Additional amounts will not be payable if a payment
on a Note is reduced as a result of any tax, assessment or other governmental charge that is required to be made pursuant to any
European Union directive on the taxation of savings income or any law implementing or complying with, or introduced to conform
to, any such directive.



 


		(13)	Additional amounts will not be payable if a payment
on a Note is reduced as a result of any withholding, deduction, tax, duty assessment or other governmental charge that would not
have been imposed but for a failure by the holder or beneficial owner of a Note (or any financial institution through which the
holder or beneficial owner holds the Note or through which payment on the Note is made) to take any action (including entering
into an agreement with the Internal Revenue Service, or a governmental authority of another jurisdiction if the holder is entitled
to the benefits of an intergovernmental agreement between that jurisdiction and the United States) or to comply with any applicable
certification, documentation, information or other reporting requirement or agreement concerning accounts maintained by the holder
or beneficial owner (or any such financial institution), or concerning ownership of the holder or beneficial owner, or any substantially
similar requirement or agreement.



 


		(14)	Additional Amounts will not be payable if a payment
on a Note is reduced as a result of any combination of items (1) through (13) above.



 


Except as specifically
provided herein, the Company will not be required to make any payment of any tax, assessment or other governmental charge imposed
by any government or a political subdivision or taxing authority of such government.


 


As used in this Note,
“United States person” means:


 


		(a)	any individual who is a citizen or resident of the
United States;



		(b)	any corporation, partnership or other entity created
or organized in or under the laws of the United States;



		(c)	any estate if the income of such estate falls within
the federal income tax jurisdiction of the United States regardless of the source of such income and



		(d)	any trust if (i) a United States court is able to exercise
primary supervision over its administration and one or more United States persons have the authority to control all of the substantial
decisions of the trust or (ii) it has a valid election in effect under applicable United States Treasury regulations to be treated
as a United States person.



 






    	10



    	 



    




 


Additionally, “non-United
States person” means a person who is not a United States person, and “United States” means the states of the
United States of America and the District of Columbia, but excluding its territories and its possessions.


 


Except as provided
below, the Notes may not be redeemed prior to maturity.


 


		(1)	The Company may, at its option, redeem the Notes if:



 


		(a)	the Company becomes or will become obligated to pay
Additional Amounts as described above;



		(b)	the obligation to pay Additional Amounts arises as
a result of any change in the laws, regulations or rulings of the United States, or an official position regarding the application

and



		(c)	the Company determines, in its business judgment,
that the obligation to pay such Additional Amounts cannot be avoided by the use of reasonable measures available to it, other
than substituting the obligor under the Notes or taking any action that would entail a material cost to the Company.



 


		(2)	The Company may also redeem the Notes, at its option,
if:



 


		(a)	any act is taken by a taxing authority of the United
States on or after April 24, 2014, whether or not such act is taken in relation to the Company or any affiliate, that results
in a substantial probability that the Company will or may be required to pay Additional Amounts as described above;



		(b)	the Company determines, in its business judgment,
that the obligation to pay such Additional Amounts cannot be avoided by the use of reasonable measures available to it, other
than substituting the obligor under the Notes or taking any action that would entail a material cost to the Company and



		(c)	the Company receives an opinion of independent counsel
to the effect that an act taken by a taxing authority of the United States results in a substantial probability that the Company
will or may be required to pay the Additional Amounts described above, and delivers to the Trustee a certificate, signed by a
duly authorized officer, stating that based on such opinion the Company is entitled to redeem the Notes pursuant to their terms.



 


Any redemption of the Notes as set forth
in clauses (1) or (2) above shall be in whole, and not in part, and will be made at a redemption price equal to 100% of the principal
amount of the Notes Outstanding plus accrued interest thereon to the date of redemption. Holders shall be given not less than 30
days’ nor more than 60 days’ prior notice by the Trustee of the date fixed for such redemption.


 


All terms used in this Note which are defined
in the Indenture shall have the meanings assigned to them in the Indenture. The Notes are governed by the laws of the State of
New York.
