Management is responsible
for Rialtos compliance with the servicing criteria. Our responsibility is to express an opinion on Managements Assertion about Rialtos compliance with the relevant servicing criteria based on our examination.

Our examination was conducted in accordance with standards of the Public Company Accounting Oversight Board (PCAOB) (United States) and, accordingly, included
examining on a test basis, evidence about Rialtos compliance with the servicing criteria and performing such other procedures as we considered necessary in the circumstances. Our examination included a selection of samples of transactions and
compliance activities related to the platform during the examination period and determining whether Rialto processed those transactions and performed those activities in compliance with the relevant servicing criteria. Our testing of selected
transactions and compliance activities was

limited to calculations, reports, and activities performed by Rialto during the period covered by this report. Our procedures did not include determining whether errors may have occurred prior to
our tests that may have affected the balances or amounts calculated or reported by Rialto during the period covered by this report for the selected transactions or any other transaction. We believe that our examination provides a reasonable basis
for our opinion. Our examination does not provide a legal determination on Rialtos compliance with the servicing criteria.

In our opinion,
Managements Assertion that Rialto complied with the relevant servicing criteria related to the aforementioned Commercial Mortgage-Asset Backed Securities Transactions, backed by the mortgage collateral pledged under such Commercial
Mortgage-Asset Backed Securities Transactions, as of December 31, 2015, and the aforementioned reporting period then ended, is fairly stated, in all material respects.
