Report of Independent Registered Public Accounting Firm

To theManagement of American Express Travel Related Services Company, Inc. (the Company, the Servicer, and the Asserting
Party),

We have examined managements assertion, included in the accompanyingCertification Regarding Compliance with Applicable
Servicing Criteria, that American Express Travel Related Services Company, Inc. (the Company) complied with the servicing criteria set forth in Item 1122(d) of the Securities and Exchange Commissions Regulation AB for all
asset-backed securities transactions backed by credit and charge card receivables issued by the American Express Credit Account Master Trust and the American Express Issuance Trust II, for which transactions the Asserting Party acted as Servicer,
that were registered with the Securities and Exchange Commission pursuant to the Securities Act of 1933, as amended, where the related asset-backed securities were outstanding as of December 31, 2017 and for the period from January 1, 2017 through
December 31, 2017 (the Platform), as of December 31, 2017 and for the year then ended from January 1, 2017 to December 31, 2017, excluding criteria 1122(d)(1)(iii), 1122(d)(1)(iv), 1122(d)(2)(iii), 1122(d)(2)(vi), 1122(d)(3)(iii),
1122(d)(4)(i), 1122(d)(4)(x), 1122(d)(4)(xi), 1122(d)(4)(xii), 1122(d)(4)(xiii), and 1122(d)(4)(xv), which the Company has determined are not applicable to the servicing activities performed by it with respect to the Platform.Appendix B to
managements assertion identifies the individual asset-backed transactions and securities defined by management as constituting the Platform. The Companys management is responsible for its assertion and for the Companys compliance
with the applicable servicing criteria. Our responsibility is to express an opinion on managements assertion about the Companys compliance with the applicable servicing criteria based on our examination.

Our examination was conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States) and in accordance with
attestation standards established by the American Institute of Certified Public Accountants. Those standards require that we plan and perform the examination to obtain reasonable assurance about whether managements assertion about compliance
with the applicable servicing criteria is fairly stated, in all material respects, and, accordingly, included examining, on a test basis, evidence about the Companys compliance with the applicable servicing criteria and performing such other
procedures as we considered necessary in the circumstances. Our examination included testing of selected asset-backed transactions and securities that comprise the Platform, testing of selected servicing activities related to the Platform, and
determining whether the Company processed those selected transactions and performed those selected activities in compliance with the applicable servicing criteria. Our procedures were limited to the selected transactions and servicing activities
performed by the Company during the period covered by this report. Our procedures were not designed to detect noncompliance arising from errors that may have occurred prior to or subsequent to our tests that may have affected the balances or amounts
calculated or reported by the Company during the period covered by this report. We believe that our examination provides, and that the evidence we obtained is sufficient and appropriate to provide, a reasonable basis for our opinion. Our examination
does not provide a legal determination on the Companys compliance with the servicing criteria.

In our opinion, managements assertion that the
Company complied with the aforementioned applicable servicing criteria as of and for the year ended December 31, 2017 for the Platform is fairly stated, in all material respects.
