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
pending and potential legal actions, arbitration proceedings, claims, investigations, examinations, information gathering requests, subpoenas, inquiries and matters relating to compliance with laws and regulations (collectively, legal proceedings).

A putative merchant class action in the Eastern District of New York, consolidated in 2011 and collectively captioned In re: American
Express Anti-Steering Rules Antitrust Litigation (II), alleged that provisions in American Express merchant agreements prohibiting merchants from differentially surcharging American Express cards or steering a customer to use another
networks card or another type of general-purpose card (anti-steering and nondiscrimination contractual provisions) violate U.S. antitrust laws. On January 15, 2020, American Express motion to compel arbitration of
claims brought by merchants who accept American Express cards and to dismiss claims of merchants who do not was granted. The plaintiffs in this action have sought leave to file a motion seeking the right to file an interlocutory appeal.

On February 25, 2020, American Express was named as a defendant in a case filed in the Superior Court of California, Los Angeles County,
captioned Laurelwood Cleaners LLC v. American Express Co., et al., in which the plaintiff seeks a public injunction prohibiting American Express from enforcing its anti-steering and nondiscrimination provisions and from requiring merchants
to offer the service of Amex-card acceptance for free. American Express intends to vigorously defend the case.

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.

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.

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 subsidiary,
American Express National Bank (AENB)), Exela Technologies, Inc. (Exela) (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 all or a portion of 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, 2019, 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,
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 has confirmed to the Depositor and TRS that it remediated the instance of noncompliance
related to the Trust by distributing to investors the reports that had not been delivered previously in the manner specified under the related transaction agreements. In addition, The Bank of New York Mellon identifies in its report certain
remediation efforts it has taken with respect to the instance of noncompliance with servicing criterion 1122(d)(3)(i)(A), which include:



| |  |  | transaction identifiers will be verified and made uniform, as needed, between The Bank of New York Mellons
investor reporting website and the system that generates investor reports;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | all desktop procedures for the platform were reviewed to make sure the correct transaction identifiers are listed
for all reports that need to be made available to investors on The Bank of New York Mellons investor reporting website; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

---

| |  |  | a review of The Bank of New York Mellons website was undertaken on the relevant payment dates to verify
that all pertinent reports had been successfully posted.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------

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
2019, TRS proprietary facilities conducted paper payment remittance processing services and performed billing dispute services. Exela (through its wholly owned subsidiary, Regulus West, LLC) also performed paper payment remittance processing
services at three locations in the United States. As a remittance processor, Exela 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, Exela 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 Exela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 Exela or The
Bank of New York Mellon.

Item 1123 of Regulation AB: Servicer Compliance Statement.

Each of TRS, AENB, and Exela has been identified by the registrant as a servicer or subservicer with respect to the pool assets held by the
Trust for all or a portion of 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.
