KEY RATING DRIVERS

Quality of Wholesale Receivables: The trust receivables backing this series have a high percentage of floorplan loans backing new vehicles (90.3%) and strong aging distribution, with only 5.9% of inventory aged past 270 days. The receivables are geographically diverse.

Adequate Diversification: The top 20 dealers in the trust represent 13.3% of the receivables balance as of Jan. 6, 2015. Dealers are subject to concentration limits, mitigating the risks associated with individual dealer defaults and losses. Concentration limits are also in place to limit exposure to individual vehicle types, manufacturers and segments.

Strength of Dealer Network: Based on a review of dealer financial metrics, the financial health of Ally's dealer network in 2014 is stable, with the majority of dealers profitable at income levels historically high through the third quarter. The U.S. unemployment rate and other domestic macroeconomic indicators drove auto sales historically higher in 2014, which benefitted auto manufacturers and dealers nationwide.

Stable Trust Performance: AMOT is experiencing consistent performance trends, including stable MPRs, low agings and minimal dealer defaults. However, due to increased competition in the floorplan lending market, yields have decreased each year since 2011, averaging 4.03% in 2014.

Sufficient Credit Enhancement: Initial credit enhancement (CE) for the class A notes is 26.5% (25.5% subordination and 1% reserve account, both of initial note balance), consistent with the prior 2014 series issued. Structural features such as early amortization triggers mitigate risks of dealer/manufacturer defaults/bankruptcies.

Consistent Origination and Servicing: Ally demonstrates adequate abilities as originator, underwriter and servicer, as evidenced by loss performance and limited exposure to dealer defaults.

Legal Analysis: The legal structure of the transaction provides that a bankruptcy of Ally would not impair the timeliness of payments on the securities.

RATING SENSITIVITY

To conduct rating sensitivity for the issued notes, under a category B Dealer Floorplan platform, Fitch assumes portfolio default levels at 10%, 25%, and 40%, and under two recovery-level scenarios of 50% and 30%. Fitch modeled the series with the assumption that the above defaults have occurred and recoveries stressed accordingly, reflecting asset performance in a stressed environment. Remaining expected loss levels were compared with the stressed loss assumption grid commensurate with various rating levels.
