Exhibit 33.3

[FIRST REPUBLIC BANK LOGO]

Management Assessment

Management of
First Republic Bank (the Bank) is responsible for assessing compliance with the applicable servicing criteria set forth in Item 1122(d) of Regulation AB of the Securities and Exchange Commission relating to the servicing of residential mortgage
loans serviced for others (the Platform) as of and for the year ended December 31, 2015, except for servicing criteria 1122(d)(1)(iii), 1122(d)(1)(v), 1122(d)(2)(iv), 1122(d)(3)(i)(C), and 1122(d)(4)(xv), which the Bank has determined are not
applicable to the activities it performs with respect to the Platform. Appendix A identifies the individual asset-backed transactions and securities defined by management as constituting the Platform.

With respect to servicing criteria 1122(d)(4)(iv), 1122(d)(4)(xi), and 1122(d)(4)(xii), management has engaged various vendors to perform the activities
required by these servicing criteria. The Banks management has determined that none of these vendors is considered a servicer as defined in Item 1101(j) of Regulation AB, and the Banks management has elected to take
responsibility for assessing compliance with the servicing criteria applicable to each vendor as permitted by the SECs Compliance and Disclosure Interpretation (C&DI) 200.06, Vendors Engaged by Servicers(C&DI
200.06) (formerly SEC Manual Telephone Interpretation 17.06). Management has policies and procedures in place designed to provide reasonable assurance that the vendors activities comply in all material respects with the servicing criteria
applicable to each vendor. The Banks management is solely responsible for determining that it meets the SEC requirements to apply C&DI 200.06 for the vendors and related criteria.

The Banks management has assessed the Banks compliance with the applicable servicing criteria as of and for the year ended December 31, 2015.
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, management believes that, as of and for the year ended December 31, 2015, the Bank has complied in all material respects
with the servicing criteria set forth in Item 1122(d) of Regulation AB of the Securities and Exchange Commission relating to the servicing of the Platform.

KPMG LLP, an independent registered public accounting firm, has issued an attestation report with respect to managements assessment of compliance with
the applicable servicing criteria as of and for the year ended December 31, 2015.
