These transactions are accounted for as secured financings and therefore both the securitized retail installment contracts and the related securitization debt issued by SPEs, remain on the Condensed Consolidated Balance Sheet. The maturity of this debt is based on the timing of repayments from the securitized assets.Most of the Company's secured structured financings are in the form of public, SEC-registered securitizations. The Company also executes private securitizations under Rule 144A of the Securities Act of 1933, as amended (the "Securities Act") and periodically issues private term amortizing notes, which are structured similarly to securitizations but are acquired by banks and conduits. The Company's securitizations and private issuances generally are collateralized by vehicle retail installment contracts and loans; however, private issuances also may be collateralized by vehicle leases. |
