KEY RATING DRIVERS

High Fitch Leverage: The transaction has higher leverage than other recent Fitch-rated transactions. The pool's Fitch debt service coverage ratio (DSCR) of 1.11x is below both the year-to-date 2015 average of 1.20x and the 2014 average of 1.19x. The pool's Fitch loan-to-value (LTV) of 113.6% is above both the year-to-date 2015 average of 110% and the 2014 average of 106.2%.

Single-Tenant Properties: The pool consists of 47 (36.3%) single-tenanted properties, including collateral for three of the top 10 loans - Patriots Park, Stanford Research Park and 45 Waterview Boulevard. Patriots Park (9.9%) is 97.5% occupied by the GSA (rated 'AAA') and 45 Waterview Boulevard (2.8%) is 100% occupied by DSM Nutritional Products, Inc. (parent rating of 'A-'), both on long-term leases.

Above-Average Collateral Quality: The pool's collateral exhibits above-average quality relative to other recent Fitch-rated transactions. Thirteen properties (50.8%), including nine properties collateralizing the top 10 loans, received property quality grades of 'B+' or better. Stanford Research Park (5.2%), 100 West 57th Street (3.7%) and Hotel Andra (2.5%) received property quality grades of 'A-'.

RATING SENSITIVITIES

For this transaction, Fitch's net cash flow (NCF) was 12.8% below the most recent net operating income (NOI; for properties for which a recent 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 could result in potential rating actions on the certificates. Fitch evaluated the sensitivity of the ratings assigned to WFCM 2015-NXS1 certificates and found that the transaction displays slightly above-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 junior '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 junior 'AAAsf' certificates to 'BBB-sf' could result. The presale report includes a detailed explanation of additional stresses and sensitivities on page 13.

The master servicer will be Wells Fargo, National Association rated 'CMS1-' by Fitch. The special servicer will be Rialto Capital Advisors, LLC rated 'CSS2' by Fitch.
