The securities, which represent the fifth securitization of the year offered by AmeriCredit Financial Services, Inc. (ACF), are issued with a note guaranty insurance policy from Ambac Assurance Corporation (Ambac), whose insurer financial strength rating is 'AAA' by Fitch. The note policy ensures full and timely payment of interest and principal by the legal final distribution date. The ratings address the likelihood that noteholders will receive full payments of interest and principal in accordance with the terms of the transaction documents. The ratings are based on the terms of the financial guaranty insurance policy and insurer financial strength rating of Ambac, the transaction's sound legal and cash flow structures, and the strength of ACF as originator and servicer of the receivables.

Interest and principal on the notes are distributed monthly on the sixth day of each month, commencing on Dec. 6, 2005. Principal is distributed sequentially beginning with the class A-1 notes until paid in full. Before drawing upon the insurance policy, losses will be covered by excess spread, overcollateralization (OC), and a reserve account. Excess spread will be available to make accelerated principal payments on the notes, thereby increasing OC to its targeted level. The initial enhancement is provided by OC of 7.50% of the initial pool balance growing to 13.00% of the then outstanding pool balance, and a fully funded, non-declining reserve account of 2.00% of the initial pool balance.

The receivables in the 2005-D-A trust are simple interest receivables made with respect to new (30.98%) and used (69.02%) automobiles and light-duty trucks and vans. The weighted average APR is 16.97%. The pool is well-diversified geographically, with the largest state concentrations in California (11.9%), Texas (11.1%), Florida (10.6%), Ohio (4.2%), Pennsylvania (4.1%), and New York (4.0%). Geographic diversification acts to insulate the transaction against regional economic downturns.
