DBRS Assigns Provisional Ratings to Connecticut Avenue Securities, Series 2015-C01

DBRS, Inc. (DBRS) has today assigned the following provisional ratings to the Connecticut Avenue Securities, Series 2015-C01 (CAS 2015-C01) notes issued by Fannie Mae (the Notes):

-- $402.5 million Class 1M-1 at BBB (low) (sf)
-- $169.5 million Class 2M-1 at BBB (low) (sf)

The BBB (low) (sf) rating on the Class 1M-1 notes in this transaction reflects the 2.15% of credit enhancement provided by subordination in Group 1. The BBB (low) (sf) rating on Class 2M-1 notes reflects 2.80% of credit enhancement in Group 2. Other than the specified classes above, DBRS does not rate any other classes in this transaction.

The Notes represent unsecured general obligations of Fannie Mae, the Issuer. The Notes are subject to the credit and principal payment risk of a certain reference pool (the Reference Pool) of residential mortgages held in various Fannie Mae-guaranteed mortgage-backed securities. Cash flow from the Reference Pools will not be used to make any payment to the CAS 2015-C01 noteholders; instead, Fannie Mae will be responsible for making monthly interest payments at the note rate, and periodic principal payments on the Notes in accordance with the actual principal payments it collects from the Reference Pools. Furthermore, losses to the CAS 2015-C01 notes are not tied to the actual cumulative losses on the Reference Pool. Rather, they are calculated based on the occurrence of credit events (generally defined as delinquency of 180+ days, short sale, deed-in-lieu, sale of mortgage during the foreclosure process and real estate-owned) and a pre-determined set of loss severities within each loan group.

The reference pool is divided into two separate loan groups: The Group 1 Reference Pool contains 146,212 mortgages with original loan-to-value (LTV) ratios greater than 60% and less than or equal to 80%, and the Group 2 Reference Pool contains 88,416 mortgages with original LTV greater than 80% and lower than or equal to 97%.

The originators for the Group 1 Reference Pool are Wells Fargo Bank, N.A. (Wells Fargo, 24.9%), JPMorgan Chase Bank, N.A. (JPMCB, 7.3%) and various other originators, each comprising less than 5% of the Group 1 Reference Pool. The originators for the Group 2 Reference Pool are Wells Fargo (26.2%) and various other originators, each comprising less than 5% of the Group 2 Reference Pool.

The loans in the Group 1 Reference Pool will be serviced by Wells Fargo (24.9%), JPMCB (7.3%) and various other servicers, each comprising less than 5% of the Group 1 Reference Pool. The loans in the Group 2 Reference Pool will be serviced by Wells Fargo (26.2%) and various other servicers, each comprising less than 5% of Group 2 Reference Pool. Wells Fargo will act as the Global Agent. Fannie Mae will act as the Master Servicer.
