| VARIABLE INTEREST ENTITIES                                  | VARIABLE INTEREST ENTITIESVIEsThe Company transfers RICs and leases into newly-formed securitization trusts ("Trusts") that then issue one or more classes of notes payable backed by collateral. The Company’s continuing involvement with the Trusts is in the form of servicing assets held by the Trusts and, generally, through holding residual interests in the Trusts. These transactions are structured without recourse. The Trusts are considered VIEs under GAAP and, when the Company holds the residual interest, are consolidated because the Company has: (a) power over the significant activities of the entity as servicer of its financial assets and (b) residual interest and, in some cases of debt securities held by the Company, an obligation to absorb losses or the right to receive benefits from the VIE which are potentially significant to the VIE. When the Company does not retain any debt or equity interests in its securitizations or subsequently sells such interests it records these transactions as sales of the associated RIC.Revolving credit facilities generally also utilize Trusts that are considered VIEs. The collateral, borrowings under credit facilities and securitization notes payable of the Company's consolidated VIEs remain on the Company's Condensed Consolidated Balance Sheets. The Company recognizes finance charges and fee income on the RICs and leased vehicles and interest expense on the debt, and records a provision for loan and lease losses to cover probable inherent losses on the contracts. All of the Trusts are separate legal entities and the collateral and other assets held by these subsidiaries are owned by them and not available to other creditors.The Company also uses a titling trust to originate and hold its leased vehicles and the associated leases in order to facilitate the pledging of leases to financing facilities or the sale of leases to other parties without incurring the costs and administrative burden of retitling the lease vehicles. This titling trust is considered a VIE.On-balance sheet VIEsThe following table summarizes the assets and liabilities related to the above mentioned VIEs that are included in the Company's Condensed Consolidated Financial Statements as of the date indicated:   March 31, 2016 December 31, 2015  (in thousands)Restricted cash $1,982,611 $1,842,877Loans(1) 23,577,939 23,726,979Leased vehicles, net 7,298,521 6,516,030Various other assets 581,758 620,482Notes payable 30,515,797 30,628,837Various other liabilities 7,654 5,379(1) Includes $1.3 billion and $1.5 billion of RICs held for sale at March 31, 2016 and December 31, 2015, respectively. The Company retains servicing responsibility for receivables transferred to the Trusts and receives a monthly servicing fee on the outstanding principal balance. Supplemental fees, such as late charges, for servicing the receivables are reflected in miscellaneous income. As of March 31, 2016 and December 31, 2015, the Company was servicing $27.9 billion and $27.3 billion, respectively, of RICs that have been transferred to consolidated Trusts. The remainder of the Company’s RICs remains unpledged.NOTE 6. VARIABLE INTEREST ENTITIES (continued)Below is a summary of the cash flows received from the Trusts for the period indicated:       Three-Month PeriodEnded March 31,    2016 2015   (in thousands)Assets securitized $3,621,496 $3,981,855       Net proceeds from new securitizations (1) 2,633,626 3,060,862 Cash received for servicing fees (2) 194,365 159,802 Net distributions from Trusts (2) 431,591 300,487 Total cash received from securitization trusts $3,259,582 $3,521,151 (1)  Includes additional advances on existing securitizations.(2) These amounts are not reflected in the accompanying Condensed Consolidated Statements of Cash Flows because the cash flows are between the VIEs and other entities included in the consolidation.Off-balance sheet VIEsThe Company has completed sales to VIEs that met sale accounting treatment in accordance with the applicable guidance. Due to the nature, purpose, and activity of these transactions, the Company determined for consolidation purposes that it either does not hold potentially significant variable interests or is not the primary beneficiary as a result of the Company's limited further involvement with the financial assets. For such transactions, the transferred financial assets are removed from the Company's Condensed Consolidated Balance Sheets. In certain situations, the Company remains the servicer of the financial assets and receives servicing fees that represent adequate compensation, and may reacquire assets from the Trusts through the exercise of an optional clean-up call, as permitted through the respective servicing agreements. The Company also recognizes a gain or loss in the amount of the difference between the cash proceeds and carrying value of the assets sold. During the three-month period endedMarch 31, 2016, the Company executed no off-balance sheet securitizations with VIEs in which it has continuing involvement. As of March 31, 2016 and December 31, 2015, the Company was servicing $3.4 billion and $3.9 billion, respectively, of gross RICs in off-balance sheet securitizations. Other than repurchases of sold assets due to standard representations and warranties, the Company has no exposure to loss as a result of its involvement with these VIEs.A summary of the cash flows received from the off-balance sheet Trusts for the periods indicated is as follows:  Three-Month PeriodEnded March 31,   2016 2015  (in thousands)Assets securitized $— $—     Net proceeds from new securitizations $— $—Cash received for servicing fees 15,701 5,304Total cash received from securitization trusts $15,701 $5,304 |
