(2) Below is a reconciliation of the provisions for credit losses reported in the consolidated statements of income. When a new loan commitment is made, we record the CECL allowance as a liability for unfunded loan commitments by recording a provision for credit losses.

Schedule of Amortized Cost Basis of Financing Receivables

The following tables show the amortized cost basis at the end of the respective reporting periods of the loans to borrowers experiencing financial difficulty that were modified during the period, disaggregated by class of financing receivable and type of modification. When we approve a Private Education Loan at the beginning of an academic year, we do not always disburse the full amount of the loan at the time of approval, but instead have a commitment to fund a portion of the loan at a later date (usually at the start of the second semester or subsequent trimesters). We consider borrowers to be in financial difficulty after they have exited school and have difficulty making their scheduled principal and interest payments.

(1) Deferment includes customers who have returned to school or are engaged in other permitted educational activities and are not yet required to make full principal and interest payments on the loans (e.g., residency periods for medical students or a grace period for bar exam preparation). Deferment also includes loans that have entered a forbearance after the loan modification was granted.

(2) Loans in repayment include loans on which borrowers are making full principal and interest payments after any applicable grace period (but, for purposes of the table, do not include those loans while they are in forbearance).

(3) The period of delinquency is based on the number of days scheduled payments are contractually past due.

The following tables provide information regarding the loan status of our Private Education Loans held for investment, by year of origination. 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 following tables, do not include those loans while they are in forbearance).

Schedule of 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 90 days or greater 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, and the current expected credit losses on accrued interest that will be capitalized is included in our allowance for credit losses.

December 31, 2022	$	1,177,562	$	6,609	$	8,121

(1)The allowance for uncollectible interest at June 30, 2023 represents the expected losses related to the portion of accrued interest receivable on those loans that are in repayment ($139 million of accrued interest receivable) that is not expected to be capitalized. The accrued interest receivable that is expected to be capitalized ($1.1 billion) is reserved in the allowance for credit losses.

(2)The allowance for uncollectible interest at December 31, 2022 represents the expected losses related to the portion of accrued interest receivable on those loans in repayment ($240 million of accrued interest receivable) that was not expected to be capitalized. The accrued interest receivable that was expected to be capitalized ($937 million) was reserved in the allowance for credit losses.
