AmeriCredit Financial Services Inc., the Sponsor and the servicer, is a Delaware corporation and is the originator of 100% of the automobile loan contracts. The Sponsor
purchases automobile loan contracts that are originated and assigned to it by automobile dealers and, to a lesser extent, third-party lenders and also originates automobile loan contracts directly with consumers, either directly or through a wholly

Delaware statutory trust.

The Sponsor sold and assigned the pool of initial automobile loan contracts to AFS Sensub Corp., the Depositor, a Nevada
corporation. The Depositor then sold the pool of sub-prime automobile loan contracts to the Issuing Entity and is the sole-owner of the certificate of the Issuing Entity.

AmeriCredit Financial Services of Canada Ltd., is a subsidiary of the Sponsor and AmeriCredit Corp. and is an affiliated servicer and will service a portion of automobile loan contracts in the United States on behalf
of the Issuing Entity through its service center in Peterborough, Ontario.
