(a) Asset values represent the current unpaid principal balance of outstanding consumer and commercial finance receivables and loans within the VIEs.

(b) Maximum exposure to loss represents the current unpaid principal balance of outstanding loans based on our customary representation and warranty provisions. This measure is based on the unlikely event that all of the loans have underwriting defects or other defects that trigger a representation and warranty provision and the collateral supporting the loans are worthless. This required disclosure is not an indication of our expected loss.

(c) Amounts classified as accrued expenses and other liabilities.

(d) Includes a VIE for which we have no management oversight and therefore we are not able to provide the total assets of the VIE.

(e) Our maximum exposure to loss in this VIE is a component of servicer advances made that are allocated to the trust. The maximum exposure to loss presented represents the unlikely event that every loan underlying the excess servicing rights sold defaults, and we, as servicer, are required to advance the entire excess service fee to the trust for the contractually established period. This required disclosure is not an indication of our expected loss.

Schedule Of Cash Flow Received And Paid To Nonconsolidated Securitization Entities [Table Text Block]

The following table summarizes cash flows received from and paid related to securitization entities, asset-backed financings, or other similar transfers of financial assets where the transfer is accounted for as a sale and we have a continuing involvement with the transferred assets (e.g., servicing) that were outstanding during the six months endedJune 30, 2013 and 2012. Additionally, this table contains information regarding cash flows received from and paid to nonconsolidated securitization entities that existed during each period.
