Exhibit 33.4

MANAGEMENTS ASSERTION OF COMPLIANCE

Management of the Agency and Trust division of Citibank, N.A. (or Company) is responsible for assessing compliance with the servicing criteria set
forth in Item 1122(d) of Regulation AB promulgated by the Securities and Exchange Commission.

Management has determined that the servicing criteria set
forth in Item 1122(d) of Regulation AB are applicable in regard to the servicing platform as of and for the period as follows:

Platform: Publicly-issued (i.e., transaction-level reporting initially required under the Securities Exchange Act of 1934, as
amended) and certain privately-issued (i.e., for which transaction-level reporting is required pursuant to contractual obligation) residential mortgage-backed securities issued on or after January 1, 2006, as listed in Appendix A, for
which the Company provides the following servicing functions:



| |  |  | paying agent, securities administration and trustee; or
| | - |  | -------------------------------------------------------

| |  |  | securities administration and paying agent; or
| | - |  | ----------------------------------------------

| |  |  | paying agent and trustee; or
| | - |  | ----------------------------

| |  |  | paying agent
| | - |  | ------------

The Platform also includes the transactions listed in Appendix B for which the
Company is not a party to the transaction agreements, but for which securities administration servicing functions have been outsourced to the Company by a party to the transaction agreements.

Applicable Servicing Criteria: All servicing criteria set forth in Item 1122(d), to the extent required by Item 1122(d) servicing
criteria in regards to the activities performed by the Company with respect to the Platform as to any transaction, except for the following servicing criteria: 1122(d)(1)(iii)-1122(d)(1)(iv), 1122(d)(2)(iii), 1122(d)(4)(i)-1122(d)(4)(ii) and
1122(d)(4)(iv)-1122(d)(4)(xiv), which management has determined are not applicable to the activities the Company performs with respect to the Platform (the Applicable Servicing Criteria). Servicing criterion 1122(d)(1)(v) is applicable
only to the activities the Company performs related to the mathematically accurate aggregation of information received from servicers and the accurate conveyance of such information within reports to investors. Servicing criterion 1122(d)(4)(iii) is
applicable to the activities the Company performs with respect to the Platform only as it relates to the Companys obligation to report additions, removals or substitutions on reports to investors in accordance with the transaction agreements.
With respect to servicing criteria 1122(d)(1)(ii) and 1122(d)(4)(iii), there were no activities performed during the twelve months ended December 31, 2017 with respect to the Platform, because there were no occurrences of events that would
require the Company to perform such activities.

Period: Twelve months ended December 31, 2017 (the Period).

With respect to the Platform as of and for the Period, the Companys management provides the following assertion of compliance with respect to the
Applicable Servicing Criteria:



| |  |  | The Companys management is responsible for assessing the Companys compliance with the Applicable Servicing Criteria.
| | - |  | ----------------------------------------------------------------------------------------------------------------------



| |  |  | The Companys management has assessed compliance with the Applicable Servicing Criteria. In making this assessment, management used the criteria set forth by the Securities and Exchange Commission in paragraph
(d) of Item 1122 of Regulation AB.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Based on such assessment, the Company has complied, in all material respects, with the Applicable Servicing Criteria.
| | - |  | ---------------------------------------------------------------------------------------------------------------------

KPMG LLP, an independent registered public accounting firm, has issued an attestation report with respect to Managements assertion of compliance with
the Applicable Servicing Criteria as of and for the Period.
