Securitization and Variable Interest Entities	Dec. 31, 2022
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Securitization and Variable Interest Entities	Securitization and Variable Interest Entities Consolidated VIEs We consolidate certain securitization trusts in which we have a variable interest and are deemed to be the primary beneficiary. Our consolidation policy is further discussed in Note 1. The VIEs are SPEs with portfolio loans securing debt obligations. The SPEs were created and designed to transfer credit and interest rate risk associated with consumer loans through the issuance of collateralized notes and trust certificates. We make standard representations and warranties to repurchase or replace qualified portfolio loans. Aside from these representations, the holders of the asset-backed debt obligations have no recourse to the Company if the cash flows from the underlying portfolio loans securing such debt obligations are not sufficient to pay all principal and interest on the asset-backed debt obligations. We hold a significant interest in these financing transactions through our ownership of a portion of the residual interest in certain VIEs. In addition, in some cases, we invest in the debt obligations issued by the VIE. Our investments in consolidated VIEs eliminate in consolidation. The residual interest is the first VIE interest to absorb losses should the loans securing the debt obligations not provide adequate cash flows to satisfy more senior claims and is the interest that we expect to absorb the expected gains and losses of the VIE. Our exposure to credit risk in sponsoring SPEs is limited to our investment in the VIE. VIE creditors have no recourse against our general credit. As of December 31, 2022 and 2021, we had 6 and 13 consolidated VIEs, respectively, on our consolidated balance sheets. During the year ended December 31, 2022, we exercised securitization clean up calls related to 9 consolidated VIEs, and established 2 consolidated VIEs. The assets of consolidated VIEs that were included in our consolidated balance sheets may only be used to settle obligations of consolidated VIEs and were in excess of those obligations as of December 31, 2022 and 2021. Intercompany balances are eliminated upon consolidation. Nonconsolidated VIEs We have created and designed personal loan and student loan trusts to transfer associated credit and interest rate risk associated with the loans through the issuance of collateralized notes and residual certificates. We have a variable interest in the nonconsolidated loan trusts, as we own collateralized notes and residual certificates in the loan trusts that absorb variability. We also have continuing, non-controlling involvement with the trusts as the servicer. As servicer, we have the power to perform the activities which most impact the economic performance of the VIE, but since we hold an insignificant financial interest in the trusts, we are not the primary beneficiary. This financial interest represents the equity ownership interest in the loan trusts, wherein there is an obligation to absorb losses and the right to receive benefits from residual certificate ownership. The maximum exposure to loss as a result of our involvement with the nonconsolidated VIEs is limited to our investment. We did not provide financial support to any nonconsolidated VIEs beyond our initial equity investment. There are no liquidity arrangements, guarantees or other commitments by third parties that may affect the fair value or risk of our variable interests in nonconsolidated VIEs. As of December 31, 2022 and 2021, we had investments in 23 and 33 nonconsolidated VIEs, respectively. During the year ended December 31, 2022, we exercised securitization clean up calls on 9 nonconsolidated VIEs and collapsed the associated trusts, as well as consolidated 1 previously nonconsolidated VIE.
