Receivables [Abstract] |
Allowance for Loan Losses | Allowance for Loan Losses Our provision for credit losses represents the periodic expense of maintaining an allowance sufficient to absorb incurred probable losses in the held-for-investment loan portfolios. The evaluation of the allowance for loan losses is inherently subjective, as it requires material estimates that may be susceptible to significant changes. We believe the allowance for loan losses is appropriate to cover probable losses incurred in the loan portfolios. See Note 2, “Significant Accounting Policies — Allowance for Loan Losses — Allowance for Private Education Loan Losses, — Allowance for Personal Loans, and — Allowance for FFELP Loan Losses” for a more detailed discussion.

Troubled Debt Restructurings All of our loans are collectively assessed for impairment, except for loans classified as TDRs (where we conduct individual assessments of impairment). At December 31, 2018 and 2017, 6.4 percent and 4.9 percent, respectively, of our loans then currently in full principal and interest repayment status were subject to interest rate reductions made under our rate modification program. Once a loan qualifies for TDR status, it remains a TDR for allowance purposes for the remainder of its life. As of December 31, 2018 and 2017, approximately 57 percent and 66 percent, respectively, of TDRs were classified as such due to their forbearance status. See Note 2, “Significant Accounting Policies — Allowance for Loan Losses” for a more detailed discussion. Within the Private Education Loan portfolio, loans greater than 90 days past due are considered to be nonperforming. FFELP Loans are at least 97 percent guaranteed as to their principal and accrued interest by the federal government in the event of default and, therefore, we do not deem FFELP Loans as nonperforming from a credit risk standpoint at any point in their life cycle prior to claim payment, and we continue to accrue interest through the date of claim. At December 31, 2018 and 2017, all of our TDR loans had a related allowance recorded. The following table provides the recorded investment, unpaid principal balance and related allowance for our TDR loans.

(1) | Deferment includes customers who have returned to school or are engaged in other permitted educational activities and are not yet required to make payments on the loans (e.g., residency periods for medical students or a grace period for bar exam preparation).
(2) | Loans for customers who have requested extension of grace period generally during employment transition or who have temporarily ceased making full payments due to hardship or other factors, consistent with established loan program servicing policies and procedures.
(3) | Loans in repayment include loans on which borrowers are making interest only or fixed payments, as well as loans that have entered full principal and interest repayment status after any applicable grace period.
(4) | The period of delinquency is based on the number of days scheduled payments are contractually past due.
The following table provides the amount of modified loans (which includes forbearance and reductions in interest rates) that became TDRs in the periods presented. Additionally, for the periods presented, the table summarizes charge-offs occurring in the TDR portfolio, as well as TDRs for which a payment default occurred in the relevant period presented and within 12 months of the loan first being designated as a TDR. We define payment default as 60 days past due for this disclosure.

_______ (1) Represents the principal balance of loans that have been modified during the period and resulted in a TDR. Private Education Loan Key Credit Quality Indicators FFELP Loans are at least 97 percent insured and guaranteed as to their principal and accrued interest in the event of default; therefore, there are no key credit quality indicators associated with FFELP Loans. For Private Education Loans, the key credit quality indicators are FICO scores, the existence of a cosigner, the loan status and loan seasoning. The FICO scores are assessed at original approval and periodically refreshed/updated through the loan’s term. The following table highlights the gross principal balance of our Private Education Loan portfolio stratified by key credit quality indicators.
