Important Notice about Information Presented in this Prospectus Supplement and the Accompanying Prospectus

We provide information to you about the CHASEseries notes in two separate documents that progressively provide more detail: (a) this prospectus supplement, which will describe the specific terms of the Class A(2015-4) notes and (b) the accompanying prospectus, which provides specific information about the CHASEseries notes and general information about all of the notes that may be issued by the issuing entity, some of which may not apply to the Class A(2015-4) notes, and financial and other information about the issuing entity’s assets.

This prospectus supplement may be used to offer and sell the Class A(2015-4) notes only if accompanied by the accompanying prospectus.

This prospectus supplement may supplement disclosure in the accompanying prospectus. If the terms of the Class A(2015-4) notes vary between this prospectus supplement and the accompanying prospectus, you should rely on the information in this prospectus supplement.

You should rely only on the information provided in this prospectus supplement and the accompanying prospectus including the information incorporated by reference. We have not authorized anyone to provide you with different information. We are not offering the Class A(2015-4) notes in any state where the offer is not permitted. We do not claim the accuracy of the information in this prospectus supplement or the accompanying prospectus as of any date other than the dates stated on their respective covers.

Capital Requirements Regulation

None of Chase Bank USA, National Association, Chase Issuance Trust, the Owner Trustee, the Indenture Trustee or any affiliate makes any representation or agreement that it is undertaking or will have undertaken to comply with the requirements of Articles 404-410 of Regulation (EU) No. 575/2013 of the European Parliament and of the Council of June 26, 2013, known as the Capital Requirements Regulation (“CRR”), which came into effect in all member states of the European Union on January 1, 2014, and replace and in some respects amend Article 122a of Directive 2006/48/EC (as amended by Directive 2009/111/EC), known as Article 122a of the Capital Requirements Directive or CRD Article 122a. As a result, a European Union regulated credit institution (and any other entity required to comply with the CRR and/or any corresponding national implementing measures) seeking to invest in the Class A(2015-4) notes (either on the closing date or thereafter) will generally be unable to satisfy the requirements of the CRR in respect of such investment. Failure to comply with one or more of the requirements set out in the CRR may result in the imposition of a penal capital charge on the notes acquired by applicable noteholders that are subject to the CRR. Prospective noteholders are responsible for analyzing their own regulatory position and are advised to consult with their own advisors regarding the suitability of the notes for investment and compliance with the CRR.

Underwriting

Subject to the terms and conditions of the underwriting agreement for the offered notes, the issuing entity has agreed to sell to each of the underwriters named below, and each of those underwriters has severally agreed to purchase, the principal amount of the offered notes opposite its name:

Underwriters	Principal Amount
J.P. Morgan Securities LLC	$	258,334,000
Barclays Capital Inc.		258,333,000
Wells Fargo Securities, LLC		258,333,000
Total	$	775,000,000

The several underwriters have agreed, subject to the terms and conditions of the underwriting agreement, to purchase all $775,000,000 aggregate principal amount of the offered notes if any of the offered notes are not purchased.

The underwriters have advised the issuing entity that the several underwriters propose initially to offer the offered notes to the public at the public offering price on the cover page of this prospectus supplement, and to certain dealers at that public offering price less a concession not in excess of 0.18000% of the principal amount of the offered notes. The underwriters may allow, and those dealers may reallow to other dealers, a concession not in excess of 0.09000% of the principal amount.

After the public offering, the public offering price and other selling terms may be changed by the underwriters.

Each underwriter of the offered notes has represented and agreed that:

• it has complied and will comply with all applicable provisions of the Financial Services and Markets Act 2000 with respect to anything done by it in relation to the offered notes in, from or otherwise involving the United Kingdom; and

• it has only communicated or caused to be communicated and it will only communicate or cause to be communicated any invitation or inducement to engage in investment activity (within the meaning of section 21 of the Financial Services and Markets Act 2000) received by it in connection with the issue or sale of any offered notes in circumstances in which section 21(1) of the Financial Services and Markets Act 2000 does not apply to the issuing entity.

Further, in relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a Relevant Member State), each underwriter of the Class A(2015-4) notes has represented and agreed that from and including the date on which the Prospectus Directive is implemented in the Relevant Member State it has not made and will not make an offer of the Class A(2015-4) notes to the public in that Relevant Member State other than to any legal entity which is a qualified investor as defined in the Prospectus Directive; provided, that no such offer of the Class A(2015-4) notes shall require the issuing entity or an underwriter to publish a prospectus pursuant to Article 3 of the Prospectus Directive or supplement a prospectus pursuant to Article 16 of the Prospectus Directive.

S-2

For the purposes of the above paragraph and this paragraph, as applicable, (A) the expression an “offer of the Class A(2015-4) notes to the public” in relation to any Class A(2015-4) notes in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the Class A(2015-4) notes to be offered so as to enable an investor to decide to purchase or subscribe the Class A(2015-4) notes, as the same may be varied in that Relevant Member State by any measure implementing the Prospectus Directive in that Relevant Member State, (B) the expression “Prospectus Directive” means Directive 2003/71/EC (and amendments thereto, including the 2010 PD Amending Directive, to the extent implemented in the Relevant Member State), and includes any relevant implementing measure in each Relevant Member State, (C) the expression “2010 PD Amending Directive” means Directive 2010/73/EU and (D) the countries comprising the “European Economic Area” are Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden and the United Kingdom.

In connection with the sale of the offered notes, the underwriters may engage in:

• over-allotments, in which members of the syndicate selling the offered notes sell more notes than the issuing entity actually sold to the syndicate, creating a syndicate short position;

• stabilizing transactions, in which purchases and sales of the offered notes may be made by the members of the selling syndicate at prices that do not exceed a specified maximum;

• syndicate covering transactions, in which members of the selling syndicate purchase the offered notes in the open market after the distribution has been completed in order to cover syndicate short positions; and

• penalty bids, by which the underwriter reclaims a selling concession from a syndicate member when any of the offered notes originally sold by that syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the offered notes to be higher than it would otherwise be. These transactions, if commenced, may be discontinued at any time.

The issuing entity and Chase USA will, jointly and severally, indemnify the underwriters against certain liabilities, including liabilities under applicable securities laws, or contribute to payments the underwriters may be required to make in respect of those liabilities. The issuing entity’s obligation to indemnify the underwriters will be limited to available finance charge collections after making all required payments and required deposits under the indenture.

The issuing entity will receive proceeds of $772,422,118 from the sale of the offered notes. This amount represents 99.66737% of the principal amount of those notes and is net of the underwriting discount of $2,325,000. The underwriting discount represents 0.30000% of the principal amount of those notes. Deposits will be made to Class C reserve subaccounts for outstanding Class C notes in an aggregate amount of $11,625,000. The issuing entity will pay these proceeds to Chase USA which will use the proceeds as described in “Use of Proceeds” in this prospectus supplement. Additional issuance expenses are estimated to be $290,000.
