 Exhibit 4.1 
 CITIBANK CREDIT CARD ISSUANCE TRUST 
 Citiseries 

Class 2013-A2 Notes 
 Issuer Certificate 
 Pursuant to Sections 202 and 301(h) of the Indenture

 Reference is made to the Amended and Restated Indenture dated as of September 26, 2000, as amended and restated as
of August 9, 2011, between Citibank Credit Card Issuance Trust (the “Issuer”) and Deutsche Bank Trust Company Americas, as trustee (as so amended and restated, the “Indenture”). Capitalized terms used herein that are not
otherwise defined have the meanings set forth in the Indenture. All references herein to designated Sections are to the designated Sections of the Indenture. 
 Section 301(h) provides that the Issuer may from time to time create a tranche of Notes either by or pursuant to an Issuer Certificate setting forth the principal terms thereof. Pursuant to this
Issuer Certificate, there is hereby created a tranche of Notes having the following terms: 
 Series Designation: Citiseries. This series
is included in Group 1. 
 Tranche Designation: $750,000,000 Floating Rate Class 2013-A2 Notes of May 2018 (Legal Maturity Date May 2020)
(hereinafter, the “Class 2013-A2 Notes”) 
 Currency: The Class 2013-A2 Notes will be payable, and denominated, in Dollars.

 Denominations: The Class 2013-A2 Notes will be issuable in minimum denominations of $100,000 and multiples of $1,000 in excess of that
amount. 
 Issuance Date: May 30, 2013 
 Initial Principal Amount: $750,000,000 
 Issue Price: 100% 

Interest Rate: The Class 2013-A2 Notes will accrue interest with respect to any interest period at a per annum rate equal to the Class 2013-A2
Note Rate for such interest period, calculated on the basis of the actual number of days in such interest period divided by 360. The “Class 2013-A2 Note Rate” means, with respect to the first interest period, 0.50190% per annum and,
with respect to each interest period thereafter, a per annum rate equal to LIBOR for such interest period plus 0.28%. 
 The Issuer will
determine LIBOR for each applicable interest period on the second business day before the beginning of that interest period. For purposes of calculating LIBOR, a business day is any day on which dealings in deposits in U.S. Dollars are transacted in
the London interbank market. 







 “LIBOR” means, as of any date of determination, the rate for deposits in U.S. Dollars for
the Designated Maturity (commencing on the first day of the relevant interest period) which appears on the Reuters Screen LIBOR01 Page as of 11:00 a.m., London time, on such date. If such rate does not appear on the Reuters Screen LIBOR01 Page, the
rate for that day will be determined on the basis of the rates at which deposits in U.S. Dollars are offered by the Reference Banks at approximately 11:00 a.m., London time, on that day to prime banks in the London interbank market for the
Designated Maturity (commencing on the first day of the relevant interest period). The Issuer will request the principal London office of each of the Reference Banks to provide a quotation of its rate. If at least two such quotations are provided,
the rate for that day will be the arithmetic mean of the quotations. If fewer than two quotations are provided as requested, the rate for that day will be the arithmetic mean of the rates quoted by major banks in New York City, selected by the
Issuer, at approximately 11:00 a.m., New York City time, on that day for loans in U.S. Dollars to leading European banks for a period of the Designated Maturity (commencing on the first day of the relevant interest period). 

“Reuters Screen LIBOR01 Page” means the display page currently so designated on the Reuters Monitor Money Rates service (or such other
page as may replace that page on that service or any successor service for the purpose of displaying comparable rates or prices). 

“Designated Maturity” means one month. 
 “Reference Banks” means four major banks in the London interbank market selected by the Issuer. 
 Scheduled Interest Payment Dates: The 24th day of each month, beginning July 2013. 
 Each
payment of interest on the Class 2013-A2 Notes will include all interest accrued from and including the preceding Interest Payment Date — or, for the first interest period, from and including the Issuance Date — to and including the day
preceding the current Interest Payment Date, plus any interest accrued but not previously paid. 
 The first deposit targeted to be made to the
Interest Funding sub-Account for the Class 2013-A2 Notes will be on the July 23, 2013 Interest Deposit Date and in an amount equal to $575,093.75. 
 Expected Principal Payment Date: May 24, 2018 
 Legal Maturity Date:
May 26, 2020 
 Monthly Principal Date: For the month in which the Expected Principal Payment Date occurs, May 24, 2018, and
for each other month, the 24th day of such month, or if such day is not a Business Day, the next following Business Day. 
 Required
Subordinated Amount of Class B Notes: $44,871,825 
 Required Subordinated Amount of Class C Notes: $59,829,075 

Controlled Accumulation Amount: $62,500,000 
 Form of Notes: The Class 2013-A2 Notes will be issued as Global Notes. The Global Notes will initially be registered in the name of Cede & Co., as nominee of The Depository Trust Company,
and will be exchangeable for individual Notes only in accordance with the provisions of Section 204(c). 

  
 2 








 Additional Issuances of Class 2013-A2 Notes: The Issuer may at any time and from time to time issue
additional Class 2013-A2 Notes, subject to the satisfaction of (i) the conditions precedent set forth in Section 311(a) and (ii) the following conditions: 

 

	 	(a)	The Issuer has obtained written confirmation from each Rating Agency that there will be no Ratings Effect with respect to the then outstanding Class 2013-A2 Notes as a
result of the issuance of such additional Class 2013-A2 Notes; 

  

	 	(b)	As of the date of issuance of the additional Class 2013-A2 Notes, all amounts due and owing to the Holders of the then outstanding Class 2013-A2 Notes have been paid
and there is no Nominal Liquidation Amount Deficit with respect to the then outstanding Class 2013-A2 Notes; 

  

	 	(c)	The additional Class 2013-A2 Notes will be fungible with the original Class 2013-A2 Notes for federal income tax purposes; 


 

	 	(d)	If Holders of the then outstanding Class 2013-A2 Notes have benefit of a Derivative Agreement, the Issuer will have obtained a Derivative Agreement for the benefit of
the Holders of the additional Class 2013-A2 Notes; and 

  

	 	(e)	The ratio of the Controlled Accumulation Amount to the Initial Dollar Principal Amount of the Class 2013-A2 Notes, including the additional Class 2013-A2 Notes, will be
equal to the ratio of the Controlled Accumulation Amount (before giving effect to the additional issuance) to the Initial Dollar Principal Amount of the Class 2013-A2 Notes, excluding the additional Class 2013-A2 Notes. 


As of the date of issuance of additional Class 2013-A2 Notes, the Outstanding Dollar Principal Amount and Nominal Liquidation Amount of the Class 2013-A2
Notes will be increased to reflect the Initial Dollar Principal Amount of the additional Class 2013-A2 Notes. 
 Any outstanding Class 2013-A2
Notes and any additional Class 2013-A2 Notes will be equally and ratably entitled to the benefits of the Indenture without preference, priority or distinction. 
 Optional Redemption Provisions other than Section 1202 “Clean-Up Call”: None 

Additional Early Redemption Events or changes to Early Redemption Events: None 
 Additional Events of Default or changes to Events of Default: None 
 Business Day:
means any day other than (a) a Saturday or Sunday or (b) any other day on which national banking associations or state banking institutions in New York, New York or South Dakota, or any other state in which the principal executive offices
of any Additional Seller are located, are authorized or obligated by law, executive order or governmental decree to be closed.
