Substitute Information provided in accordance with General Instruction J to Form 10-K:

Item 1112(b) of Regulation AB: Significant obligors of pool assets (Financial information).

The pool assets held by the American Express Credit Account Master Trust (the Trust) do not include any significant obligors.

Item 1114(b)(2) of Regulation AB: Credit enhancement and other support, except for certain derivatives instruments (Financial information).

Based on the standards set forth in Item 1114(b) of Regulation AB, no information is required in response to this Item.

Item 1115(b) of Regulation AB: Certain derivatives instruments (Financial information).

Based on the standards set forth in Item 1115(b) of Regulation AB, no information is required in response to this Item.

Item 1117 of Regulation AB: Legal proceedings.

In the ordinary course of business, American Express Company and its subsidiaries (American Express) are subject to various claims,
investigations, examinations, pending and potential legal actions, and other matters relating to compliance with laws and regulations (collectively, legal proceedings). During the last several years, as regulatory interest in credit card network
pricing to merchants or terms of merchant rules and contracts has increased, American Express has responded to many inquiries from banking and competition authorities around the world. In addition, the Department of Justice and various merchants
have initiated legal proceedings to challenge aspects of American Express card acceptance agreements with merchants on antitrust grounds.

In 2010, the DOJ, along with Attorneys General from Arizona, Connecticut, Hawaii (Hawaii has since withdrawn its claim), Idaho, Illinois,
Iowa, Maryland, Michigan, Missouri, Montana, Nebraska, New Hampshire, Ohio, Rhode Island, Tennessee, Texas, Utah and Vermont filed a complaint in the U.S. District Court for the Eastern District of New York against American Express alleging a
violation of Section 1 of the Sherman Antitrust Act. The complaint included allegations that provisions in American Express merchant agreements prohibiting merchants from steering a customer to use another networks card or another
type of general-purpose card (anti-steering and non-discrimination contractual provisions) violate the antitrust laws. The complaint sought a judgment permanently enjoining American
Express from enforcing its non-discrimination contractual provisions. The complaint did not seek monetary damages.



2



---

Following a non-jury trial, the trial court found that
the challenged provisions were anticompetitive and on April 30, 2015, the court issued a final judgment entering a permanent injunction. Following American Express appeal of this judgment, on September 26, 2016, the Court of Appeals
for the Second Circuit reversed the trial court decision and judgment in favor of American Express was entered on January 25, 2017. Eleven of the 17 states that are party to the case filed a petition with the Supreme Court seeking a review of
the Second Circuits decision. On October 16, 2017, the Supreme Court granted certiorari and oral argument was held on February 26, 2018 in the case, now captioned Ohio v. American Express Co.

In addition, individual merchant cases and a putative class action, which were consolidated in 2011 and collectively captioned In re:
American Express Anti-Steering Rules Antitrust Litigation (II), are pending in the Eastern District of New York against American Express alleging that its anti-steering provisions in merchant card acceptance agreements violate U.S. antitrust
laws. The individual merchant cases seek damages in unspecified amounts and injunctive relief.

In July 2004, American Express was named
as a defendant in another putative class action filed in the Southern District of New York and subsequently transferred to the Eastern District of New York, captioned The Marcus Corporation v. American Express Co., et al., in which the
plaintiffs allege an unlawful antitrust tying arrangement between certain of American Express charge cards and credit cards in violation of various state and federal laws. The plaintiffs in this action seek injunctive relief and an unspecified
amount of damages.

In re: American Express Anti-Steering Rules Antitrust Litigation (II) and The Marcus Corporation v.
American Express Co., et al., including a trial previously scheduled in the individual merchant cases, are stayed pending resolution of the appeal in Ohio v. American Express Co. Further proceedings are anticipated.

Individual merchants have also initiated arbitration proceedings raising similar claims concerning the anti-steering provisions in American
Express card acceptance agreements and seeking damages. American Express is vigorously defending against those claims, which are similarly stayed.

On March 8, 2016, plaintiffs B&R Supermarket, Inc. d/b/a Milams Market and Grove Liquors LLC, on behalf of themselves and
others, filed a suit, captioned B&R Supermarket, Inc. d/b/a Milams Market, et al. v. Visa Inc., et al., for violations of the Sherman Antitrust Act, the Clayton Antitrust Act, Californias Cartwright Act and unjust enrichment
in the United States District Court for the Northern District of California, against American Express Company, other credit and charge card networks, other issuing banks and EMVCo, LLC. Plaintiffs allege that the defendants, through EMVCo, conspired
to shift liability for fraudulent, faulty and otherwise rejected consumer credit card transactions from themselves to merchants after the implementation of EMV chip payment terminals. Plaintiffs seek damages and injunctive relief. An amended
complaint was filed on July 15, 2016. On September 30, 2016, the court denied American Express motion to dismiss as to claims brought by merchants who do not accept American Express cards, and on May 4, 2017, the California
court transferred the case to the United States District Court for the Eastern District of New York.

Substitute Information provided in accordance with General
Instruction J to Form 10-K:

Item 1119 of Regulation AB: Affiliations and Certain Relationships
and Related Transactions.

Information required by Item 1119 of Regulation AB has been omitted from this report on Form 10-K in reliance on the Instruction to Item 1119.

Item 1122 of Regulation AB: Compliance
with Applicable Servicing Criteria.

Each of American Express Travel Related Services Company, Inc. (TRS) (for itself and
on behalf of its wholly owned subsidiaries American Express Centurion Bank and American Express Bank, FSB), TransCentra, Inc. (formerly known as Regulus Group LLC) (TransCentra) (for itself and its wholly owned subsidiaries), and The
Bank of New York Mellon (each, a Servicing Participant) has been identified by the registrant as a party participating in the servicing function with respect to the pool assets held by the American Express Credit Account Master Trust for
the period covered by this Form 10-K. Each of the Servicing Participants has completed a report on an assessment of compliance with the servicing criteria applicable to such Servicing Participant
(each, a Report on Assessment) as of and for the year ended December 31, 2017, which Reports on Assessment are attached as exhibits to this Form 10-K. In addition, each of the
Servicing Participants has provided an attestation report (each, an Attestation Report) by a registered independent public accounting firm regarding its related Report on Assessment. Each Attestation Report is attached as an exhibit to
this Form 10-K.

Vendors

A Servicing Participant may engage one or more vendors, who are not considered servicers for purposes of Regulation AB, to perform specific and
limited, or scripted activities that address all or a portion of one or more servicing criteria applicable to such Servicing Participant. In general in these cases, the Servicing Participant has instituted policies and procedures to monitor whether
such vendors activities comply in all material respects with such servicing criteria, and may elect to take responsibility for assessing compliance with the servicing criteria applicable to such vendors activities in such Servicing
Participants Report on Assessment.

Where the Servicing Participant has not instituted such policies and procedures, or where the
Servicing Participant does not otherwise elect to take responsibility for assessing its vendors activities, the vendor is itself treated as a Servicing Participant and is required to provide its own Report on Assessment and related Attestation
Report.

Exceptions

Except as
disclosed below, no Report on Assessment or related Attestation Report has identified any material instance of noncompliance with the servicing criteria identified in such Report on Assessment as applicable to the related Servicing Participant. In
addition, no Report on Assessment or related Attestation Report has identified any material deficiency in such Servicing Participants policies and procedures to monitor vendor compliance.

The Bank of New York Mellon: The Bank of New York Mellons Report on Assessment and related Attestation Report have
identified material noncompliance with one servicing criterion applicable to The Bank of New York Mellon. With regard to servicing criterion 1122(d)(3)(i)(A), The Bank of New York Mellons report states that, during the reporting period, for
certain resecuritization and repackage transactions, certain reports to investors were not prepared in accordance with the timeframes set forth in the related transaction agreements. The Bank of New York Mellon identifies in its report certain
remediation efforts with respect to the instances of noncompliance with servicing criterion 1122(d)(3)(i)(A), which include enhancing controls in order to better ensure reports are delivered timely to investors. The Bank of New York Mellon has
confirmed to the Depositors and TRS that no instance of noncompliance with servicing criterion 1122(d)(3)(i)(A) involved the Trust or investors in the Trust. We have not independently verified the accuracy of The Bank of New York Mellons
assertions, the adequacy of its remediation efforts or the accuracy of its confirmations.

Platform Level Reports

Regulations of the Securities and Exchange Commission (the SEC) require that each Servicing Participant complete a Report on
Assessment at a platform level, meaning that the transactions covered by the Report on Assessment should include all asset-backed securities transactions involving such Servicing Participant that are backed by the same asset type. During
2017, TRS proprietary facilities conducted paper payment remittance processing services and performed billing dispute services. TransCentra also performed paper payment remittance processing services at three locations in the United States. As
a remittance processor, TransCentra is responsible for, among other services, transmitting payment information to TRS, which TRS in turn uses to update its account obligor records. In its Report on Assessment attached as Exhibit 33.2 to this Form 10-K, TransCentra defines its platform to include (i) remittance processing services it provides to customers who are issuers or servicers of asset-backed securities transactions and
(ii) who have requested confirmation of TransCentras compliance in connection with loan and/or receivables portfolios that include pool assets for asset backed securities transactions. The Bank of New York Mellon is Trustee of the Trust.
In its Report on Assessment attached as Exhibit 33.3 to this Form 10-K, The Bank of New York Mellon defines its platform to include publicly issued (i.e., transaction-level reporting initially
required under the Securities Exchange Act of 1934, as amended) asset-backed securities issued on or after January 1, 2006 (and like-kind transactions issued prior to January 1, 2006), that are subject to Regulation AB for which The Bank
of New York Mellon provides trustee, securities administration, paying agent or custodial services, as defined and to the extent applicable in the transaction agreements, other than residential mortgage-backed securities and other mortgage-related
asset-backed securities.

None of TRS or the Trust is an affiliate of TransCentra or The Bank of New York Mellon.

Item 1123 of Regulation AB: Servicer Compliance Statement.

Each of TRS, American Express Centurion Bank, American Express Bank, FSB and TransCentra has been identified by the registrant as a servicer or
subservicer with respect to the pool assets held by the Trust for the period covered by this Form 10-K. Each of them has provided a Statement of Compliance for the period covered by this Form 10-K (a Compliance Statement), in each case signed by an authorized officer thereof. Each Compliance Statement is attached as an exhibit to this
Form 10-K.
