Receivables [Abstract] |
Allowance for Credit Losses | Allowance for Credit Losses Our provision for credit losses represents the periodic expense of maintaining an allowance sufficient to absorb lifetime expected credit losses in the held for investment loan portfolios. The evaluation of the allowance for credit losses is inherently subjective, as it requires material estimates that may be susceptible to significant changes. We believe the allowance for credit losses is appropriate to cover lifetime losses expected to be incurred in the loan portfolios. See Notes to Consolidated Financial Statements, Note 2, “Significant Accounting Policies — Allowance for Credit Losses 2020 — Allowance for Private Education Loan Losses, — Allowance for FFELP Loan Losses, and — Allowance for Credit Card Loans” in our 2020 Form 10-K for a more detailed discussion.

(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. Allowance for Credit Losses - Forecast Assumptions In determining the adequacy of the allowance for credit losses, we include forecasts of college graduate unemployment and the Consumer Price Index in our loss forecasting models. We obtain forecasts for these two inputs from Moody’s Analytics. Moody’s Analytics provides a range of forecasts for each of these inputs with various likelihoods of occurring. We determine which forecasts we will include in our estimation of allowance for credit losses and the associated weightings for each of these inputs. At both January 1, 2020 (the initial adoption date of the Financial Accounting Standards Board’s Accounting Standards Update No. 2016-13, “Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” or “CECL”), and September 30, 2021, we used the Base (50th percentile likelihood of occurring)/S1 (stronger near-term growth scenario with 10 percent likelihood of occurring)/S3 (downside scenario with 10 percent likelihood of occurring) scenarios and weighted them 40 percent, 30 percent and 30 percent, respectively. Management reviews both the scenarios and their respective weightings each quarter in determining the allowance for credit losses. Provisions for credit losses in the first nine months of 2021 decreased by $427 million compared with the year-ago period. During the first nine months of 2021, the provision for credit losses was primarily affected by improvements in the economic forecasts, the use of the more balanced weightings of the various Moody’s Analytics scenarios described above, and faster prepayment speeds, as compared to the year-ago period. For the nine months ended September 30, 2020, we recognized a significant increase in the provision for credit losses primarily in response to the COVID-19 pandemic and surge in COVID-19 infections that occurred in third quarter 2020. In response to the increase in COVID-19, at September 31, 2020, we were using Moody’s Analytics Base and S4 downturn scenarios, weighted 50 percent each, in determining the allowance for credit losses. During the first quarter of 2021, we increased our estimates of future prepayment speeds during both the two-year reasonable and supportable period as well as the remaining term of the underlying loans. These faster estimated prepayment speeds during the two-year reasonable and supportable period reflect the significant improvement in economic forecasts, as well as the implementation of an updated prepayment speed model. We experienced higher prepayments during the COVID-19 pandemic, when unemployment rates were elevated, than we would have expected based upon our experience during past financial crises. Troubled Debt Restructurings (“TDRs”) All of our loans are collectively assessed for impairment, except for loans classified as TDRs (where we conduct individual assessments of impairment). We adjust the terms of loans for certain borrowers when we believe such changes will help our customers manage their student loan obligations, achieve better student outcomes, and increase the collectability of the loans. These changes generally take the form of a temporary forbearance of payments, a temporary interest rate reduction, a temporary interest rate reduction with a permanent extension of the loan term, and/or a short-term extended repayment alternative. When we give a borrower facing financial difficulty an interest rate reduction, we temporarily reduce the contractual interest rate on a loan to 4.0 percent for a two-year period and, in the vast majority of cases, permanently extend the final maturity date of the loan. The combination of these two loan term changes helps reduce the monthly payment due from the borrower and increases the likelihood the borrower will remain current during the interest rate modification period as well as when the loan returns to its original contractual interest rate. At September 30, 2021 and September 30, 2020, 9.2 percent and 8.8 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 both September 30, 2021 and December 31, 2020, approximately 47 percent of TDRs were classified as such due to their forbearance status. For additional information, including the process we use for determining whether a loan will be classified as a TDR, see Notes to Consolidated Financial Statements, Note 2, “Significant Accounting Policies —Allowance for Loan Losses 2020,” and Note 7, “Allowance for Credit Losses” in our 2020 Form 10-K. Within the Private Education Loan portfolio, loans greater than 90 days past due are 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 perspective at any point in their life cycle prior to claim payment and continue to accrue interest on those loans through the date of claim. At September 30, 2021 and December 31, 2020, 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 (but, for purposes of the table, do not include those loans while they are in forbearance). (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 include 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 Loans Held for Investment - Key Credit Quality Indicators FFELP Loans are at least 97 percent 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 tables highlight the gross principal balance of our Private Education Loan portfolio, by year of origination, stratified by key credit quality indicators.

_______ (1)For some students, going back to school in the fall was not an option because of the pandemic, or for other reasons. Therefore, some students are taking a “gap year” before returning to school. In 2020, for those students that had unexpectedly separated from school, we provided an extension of time through fall 2021 to re-enroll, before beginning their grace period that occurs prior to entering full principal and interest repayment status. At December 31, 2020, the loans in the “in-school/grace/deferment” category above include $401 million of Private Education Loans whose borrowers did not return to school in the fall of 2020 and who received such extension of time from us to re-enroll before beginning their grace period. At December 31, 2020, the loans in the “in forbearance” category above include $30 million of Private Education Loans whose borrowers did not return to school in the fall of 2020 and who received such extension of time from us to re-enroll before beginning their grace period. At December 31, 2020, the loans in the “in repayment” category above include $609 million of Private Education Loans whose borrowers did not return to school in the fall of 2020 and who received such extension of time from us to re-enroll before beginning their grace period. This program ended in September 2021. (2)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). (3)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. (4)The period of delinquency is based on the number of days scheduled payments are contractually past due. Accrued Interest Receivable The following table provides information regarding accrued interest receivable on our Private Education Loans. The table also discloses the amount of accrued interest on loans greater than 90 days past due as compared to our allowance for uncollectible interest on loans making full interest payments. The majority of the total accrued interest receivable represents accrued interest on deferred loans where no payments are due while the borrower is in school and fixed-pay loans where the borrower makes a $25 monthly payment that is smaller than the interest accruing on the loan in that month. The accrued interest on these loans will be capitalized to the balance of the loans when the borrower exits the grace period after separation from school. The allowance for this portion of interest is included in our loan loss reserve. The allowance for uncollectible interest exceeds the amount of accrued interest on our 90 days past due Private Education Loan portfolio for all periods presented.
