MANAGEMENTS ASSESSMENT OF

COMPLIANCE WITH REGULATION AB CRITERIA

Principal Real Estate Investors, LLC and Principal Global Investors, LLC, (the Assessing Parties) are responsible for assessing
compliance for the transactions listed on Attachment A for the period January 1, 2017 through December 31, 2017, (the Reporting Period) with the servicing criteria set forth in Title 17, Section 229.1122(d) of the Code of
Federal Regulations (the CFR), except for the criteria set forth in Sections 229.1122(d)(1)(ii)-(iii), 229.1122(d)(3)(i)  (iv), 229.1122(d)(4)(ix), and 229.1122(d)(4)(xv), in the CFR, which the Assessing Parties have concluded are
not applicable to the servicing of the transactions listed on Attachment A, backed by commercial mortgage loans and primarily serviced by the Assessing Parties (the Applicable Servicing Criteria).

The Assessing Parties have assessed compliance with the Applicable Servicing Criteria for the Reporting Period and have concluded that the
Assessing Parties have complied, in all material respects, with the Applicable Servicing Criteria for the transactions listed on Attachment A backed by commercial mortgages primarily serviced by the Assessing Parties.

With respect to servicing criteria 1122(d)(1)(i) and 1122(d)(4)(i) (the Criteria), the Assessing Parties have engaged various
vendors to perform certain activities required by this Criteria. The Assessing Parties have determined that none of these vendors are considered a servicer as defined in Item 1101(j) of Regulation AB, and the Assessing Parties have
elected to take responsibility for assessing compliance with the servicing criteria applicable to each vendor as permitted by Regulation AB Compliance and Disclosure Interpretations of the Division of Corporation Finance, Section 200.06,
Vendors Engaged by Servicers (C&DI 200.06). The Assessing Parties have assessed that it 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 Assessing Parties are solely responsible for determining that it meets the SEC requirements to apply C&DI 200.06 for the vendors and related criterion as described herein.

Ernst & Young LLP, an independent registered public accounting firm, has issued an attestation report on the assessment of compliance
with the Applicable Servicing Criteria for the Reporting Period as set forth in this assessment.
