When the transaction launched on Sept. 28, 2015, the Class X-B notes referenced both the Class A-S and Class B notes, and was issued an expected rating of 'AA-sf'. The Class X-B notes now reference only Class A-S notes, resulting in a rating of 'AAAsf'.

The certificates represent the beneficial ownership interest in the trust, primary assets of which are 56 loans secured by 102 commercial properties having an aggregate principal balance of approximately $1.18 billion as of the cut-off date. The loans were contributed to the trust by Morgan Stanley Mortgage Capital Holdings LLC, Bank of America, National Association, CIBC, Inc., and Starwood Mortgage Funding III LLC.

Fitch reviewed a comprehensive sample of the transaction's collateral, including site inspections on 73.2% of the properties by balance, cash flow analysis of 79.7%, and asset summary reviews on 79.7% of the pool.

KEY RATING DRIVERS

Higher Than Average Fitch Leverage: The pool has a Fitch stressed debt service coverage ratio (DSCR) of 1.09x and a stressed loan to value (LTV) of 113.4%. This represents higher leverage than other recent Fitch-rated fixed-rate multiborrower transactions. The 2014 and YTD 2015 Fitch DSCR and LTV averages are 1.19x and 106.2% and 1.21x and 108.9%, respectively.

Above-Average Pool Concentration: The top 10 loans comprise 53.5% of the pool, which is worse than recent averages of 50.5% and 48.2% for 2014 and YTD 2015, respectively. Additionally, the loan concentration index (LCI) and sponsor concentration index (SCI) are 406 and 441, respectively, both of which are greater than recent respective averages of 387 and 419 for YTD 2015.

High-Quality Collateral: Three properties (The Roosevelt New Orleans Waldorf Astoria, The Villas at Dorsey Ridge and The Chapman Apartments) making up 18% of the pool on which site inspections were performed were assigned property quality grades of 'A-'. The majority of the inspected pool (73.3%) were assigned a property quality grade of 'B+' or 'B'. Only 8.8% of the inspected pool were assigned property quality grades of 'B-' or 'C+', indicating below-average property quality.

RATING SENSITIVITIES
For this transaction, net charge-offs (NCF) were 10.1% 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 MSBAM 2015-C25 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 'AA-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 'BBBsf' 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 Deloitte. The third-party due diligence information was provided on Form ABS Due Diligence-15E and focused on a comparison and re-computation of certain characteristics with respect to each mortgage loan. Fitch considered this information in its analysis and the findings did not have an impact on our analysis.
