Exhibit 33.1 Certification Regarding Compliance with Applicable Servicing Criteria  1.
Chase Bank USA, National Association (the Asserting Party) is responsible for assessing compliance
with the servicing criteria applicable to it under paragraph (d) of Item 1122 of Regulation AB, as of and for the 12-month period ending December 31, 2018 (the Reporting Period), as set
forth in Appendix A hereto. The transactions covered by this report include asset-backed securities transactions involving credit card receivables, for which transactions the Asserting Party acted as servicer, that were registered with the

Appendix B hereto;  2.
The Asserting Party has engaged one vendor (the Vendor), which is not considered a
servicer as defined in Item 1101(j) of Regulation AB, to perform specific, limited or scripted activities, and, as permitted by Compliance and Disclosure Interpretation 200.06, Vendors Engaged by Servicers (CD&I 200.06)

the servicing criteria applicable to such Vendors activities as set forth in Appendix A hereto.1 The Asserting Party has policies and procedures in place designed to provide reasonable
assurance that the Vendors activities comply in all material respects with the servicing criteria applicable to such Vendor. The Asserting Party is solely responsible for determining that it meets the SEC requirements to apply CD&I 200.06
for the Vendor and related criterion;  3.
Except as set forth in paragraph 4 below, the Asserting Party used the criteria set forth in paragraph
(d) of Item 1122 of Regulation AB to assess the compliance with the applicable servicing criteria;  4.
The criteria listed in the column titled Inapplicable Servicing Criteria on Appendix A hereto are
inapplicable to the Asserting Party based on the activities it performs with respect to the Platform;  5.
The Asserting Party has complied, in all material respects, with the applicable servicing criteria as of
December 31, 2018 and for the Reporting Period with respect to the Platform taken as a whole.  6.
The Asserting Party has not identified and is not aware of any material instance of noncompliance by the Vendor
with the applicable servicing criteria as of December 31, 2018 and for the Reporting Period with respect to the Platform taken as a whole;  1
Note that Wells Fargo Bank, National Association (Wells Fargo) in its capacity as Trustee is not
considered a Vendor for purposes of this report. Wells Fargo is considered a servicer as defined in Item 1101(j) of Regulation AB, and as such, will provide its own report regarding its compliance with Regulation AB.
