The certificates represent the beneficial ownership interest in the trust, primary assets of which are 65 loans secured by 96 commercial properties having an aggregate principal balance of approximately $931.6 million as of the cut-off date. The loans were contributed to the trust by German American Capital Corporation, Cantor Commercial Real Estate Lending, L.P., Key Bank National Association and The Bank of New York Mellon.

Fitch reviewed a comprehensive sample of the transaction's collateral, including site inspections on 66.2% of the properties by balance, and asset summary reviews and cash flow analysis of 78% of the pool.

KEY RATING DRIVERS

High Fitch Leverage: The pool demonstrates high leverage statistics with a Fitch debt service coverage ratio (DSCR) and loan-to-value (LTV) of 1.13x and 110.9%, respectively. Excluding the credit-assessed 11 Madison Avenue (7.5% of pool), the Fitch DSCR and LTV are 1.10x and 114.9%. The 2015 year-to-date average Fitch DSCR and LTV are 1.19x and 109.4%, respectively.

Credit Opinion Loan: One loan, 11 Madison Avenue (7.5% of the pool), has an investment-grade credit opinion of 'A-' on a stand-alone basis. Excluding the 11 Madison Avenue loan, Fitch's implied conduit subordination at the junior 'AAAsf' tranche is approximately 26.2% and 'BBB-sf' is approximately 8.9%.

Collateral Quality: The quality of the assets is generally considered to be above average compared to other conduit transactions. Three loans in the top 10, 11 Madison, NMS Portfolio, and The Drake, were assigned Fitch property grades in the 'A' range. As a percentage of Fitch-inspected properties, 41.2% of the pool received a property quality grade of 'B+' or higher. Five properties, 9.9% of the pool, received property quality grades in the 'A' range. Eleven inspected properties (12.0%) received a property quality grade of 'B-.'

RATING SENSITIVITIES

For this transaction, Fitch's net cash flow (NCF) was 15.3% 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). Unanticipated further declines in property-level NCF could result in higher defaults and loss severities on defaulted loans, and in potential rating actions on the certificates.

Fitch evaluated the sensitivity of the ratings assigned to COMM 2015-CCRE27 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 'A-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 page 11.
