A full list of rating actions follows at the end of this ratings action commentary.

The expected ratings are based on information provided by the issuer as November 03, 2015. Fitch does not expect to rate the $33,849,000 class G.

The certificates represent the beneficial ownership interest in the trust, primary assets of which are 39 loans secured by 69 commercial properties having an aggregate principal balance of approximately $820.6 million as of the cut-off date. The loans were contributed to the trust by Goldman Sachs Mortgage Company and Cantor Commercial Real Estate Lending, L.P.

Fitch reviewed a comprehensive sample of the transaction's collateral, including site inspections on 75.9% of the properties by balance, cash flow analysis of 87.6%, and asset summary reviews on 100% of the pool.


Fitch Leverage Below Recent Transactions: The Fitch DSCR and LTV are 1.24x and 102.2%, respectively. The leverage metrics for this transaction are better than for other recent Fitch-rated fixed-rate multiborrower transactions. The 2015 YTD average DSCR and LTV are 1.19x and 109.6% and the 2014 average DSCR and LTV were 1.19x and 106.2%, respectively.

High Pool Concentration: The top 10 loans comprise 65.5% of the pool, which is much higher than recent averages of 48.5% and 50.5% for YTD 2015 and 2014, respectively. Additionally, the LCI is 564 and the SCI is 589, both of which are higher than recent respective averages of 349 and 384 for YTD 2015.

Investment-Grade Credit Opinion Loan: The largest loan in the pool, 590 Madison (12.2% of the pool), was assigned a 'AAA' credit opinion within the context of this pool.

High Quality Collateral: Two properties, 590 Madison Avenue and Element LA, were assigned Fitch's highest property quality grade of 'A' and Deerfield Crossing was assigned a grade of 'A-'. These three properties total 32.8% of the pool in which site inspections were performed. The majority of the inspected pool (57.9%) was assigned a property quality grade of 'B+' or 'B'. Only 9.3% of the inspected pool was assigned a property quality grade of 'B-', indicating below average property quality.}


For this transaction, Fitch's NCF was 4.9% below the most recent year's 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 GSMS 2015-GS1 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 'Asf' 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 10 - 11.
