Exhibit 34.15   LOGO  LOGO  Report of Independent Registered Public
Accounting Firm To the Board of Directors Pentalpha Surveillance, LLC We have examined managements assertion, included in the accompanying Managements Report on Assessment of 2018 Compliance with Applicable Regulation AB
Servicing Criteria (Managements Assertion), that Pentalpha Surveillance, LLC (the Company) complied with the servicing criteria set forth in Item 1122(d) of the Securities and Exchange Commissions Regulation AB for services by the
Company that are encompassed by contractual obligations to perform Regulation AB reporting (Platforms A and B), including only those asset-backed securities transactions defined below, as of and for the year ended December 31, 2018, excluding the
following criteria set forth in Items 1122(d)(1)(i-v), 1122(d)(2)(i-vii), 1122(d)(3)(ii-iv), 1122(d)(4)(i-vi) and 1122(d)(4)(viii-xv), which management has determined are not applicable to the activities performed by the Company with respect to
Platform A, and excluding the following criteria set forth in Items 1122(d)(1)(i-v), 1122(d)(2)(i-vii), 1122(d)(3)(i)(C-D), 1122(d)(3)(ii-iv), 1122(d)(4)(i-vi) and 1122(d)(4)(viii-xv), which management has determined are not applicable to the
activities performed by the Company with respect to Platform B covered by this report. Appendix B to Managements Assertion identifies the individual asset-backed transactions defined by management as constituting Platforms A and B. Management
is responsible 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 attestation standards of the Public Company Accounting Oversight Board (United States) and,
accordingly, included examining, on a test basis, evidence about the Companys compliance with the applicable servicing criteria, including tests on a sample basis of the servicing activities related to Platforms A and B, determining whether
the Company performed those activities in compliance with the servicing criteria during the specified period and performing such other procedures as we considered necessary in the circumstances. Our procedures were limited to selected servicing
activities performed by the Company during the period covered by this report and, accordingly, such samples may not have included servicing activities related to each asset-backed transaction in Platforms A
and B. Further, an examination is not designed to detect noncompliance arising from errors that may have occurred prior to the period specified above 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 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 Pentalpha Surveillance, LLC complied with the aforementioned applicable servicing criteria as of and for the year ended
December 31, 2018, for Platforms A and B is fairly stated, in all material respects. /s/ RSM US LLP Los Angeles, California February 26, 2019  LOGO
