KEY RATING DRIVERS

Leverage Slightly Higher Than 2014 And 2015 Averages: The pool's Fitch debt service coverage ratio (DSCR) and loan to value (LTV) are 1.11x and 110.5%, respectively. The leverage metrics for this transaction are slightly higher than other recent Fitch-rated, fixed-rate multiborrower transactions. The 2014 average Fitch DSCR was 1.19x, and the average Fitch LTV was 106.2%. The 2015 year-to-date (YTD) averages have a DSCR and LTV of 1.21x and 109.1%, respectively.

Investment-Grade Credit Opinion Loans: Two loans totaling 6.7% of the pool have investment grade credit opinions on a stand-alone basis. Pearlridge Center (4.3%) has an investment grade opinion of 'BBBsf' and Scottsdale Quarter (2.5%) has an investment grade opinion of 'BBBsf'.

More Diverse Pool: The top 10 loans comprise 40.3% of the pool, which is lower than recent averages of 50.5% and 47.8% for 2014 and YTD 2015, respectively. Additionally, the loan concentration index (LCI) is 289, which is lower than the YTD 2015 average of 341.

RATING SENSITIVITIES
For this transaction, Fitch's net cash flow (NCF) was 10.8% below the most recent year's net operating income (NOI; for properties for which a full year NOI was provided, excluding properties that were stabilizing during this period). The following rating sensitivities describe how the ratings would react to further NCF declines below Fitch's NCF. The implied rating sensitivities are only indicative of some of the potential outcomes and do not consider other risk factors to which the transaction is exposed. Stressing additional risk factors may result in different outcomes. Furthermore, the implied ratings, after the further NCF stresses are applied, are more akin to what the ratings would be at deal issuance had those further stressed NCFs been in place at that time.

Fitch evaluated the sensitivity of the ratings assigned to COMM 2015-CCRE25 certificates and found that the transaction displays average sensitivity to further declines in NCF. In a scenario in which NCF declined a further 20% from Fitch's NCF, a downgrade of the senior 'AAAsf' certificates to 'BBB+sf' could result. In a more severe scenario, in which NCF declined a further 30% from Fitch's NCF, a downgrade of the senior 'AAAsf' certificates to 'BBB-sf' could result. The presale report includes a detailed explanation of additional stresses and sensitivities on pages 11 - 12.

DUE DILIGENCE USAGE
Fitch was provided with third-party due diligence information from Ernst & Young LLP.

Fitch considered this information in its analysis and the findings did not have an impact on our analysis.
