(a)Includes all loans not included in the categories of special mention, substandard or nonaccrual. (b)Includes loans with an internal rating of special mention, substandard loans for which the accrual of interest has not been discontinued and nonaccrual loans. Special mention loans have potential credit weaknesses that deserve management’s close attention, such as loans to borrowers who may be experiencing financial difficulties that may result in deterioration of repayment prospects from the borrower at some future date. Accruing substandard loans have a well-defined weakness, or weaknesses, such as loans to borrowers who may be experiencing losses from operations or inadequate liquidity of a degree and duration that jeopardizes the orderly repayment of the loan. Substandard loans are also distinguished by the distinct possibility of loss in the future if these weaknesses are not corrected. Nonaccrual loans are loans for which the accrual of interest has been discontinued. For further information regarding nonaccrual loans, refer to the Nonperforming Assets subheading in Note 1 - Basis of Presentation and Accounting Policies. These categories are generally consistent with the "special mention" and "substandard" categories as defined by regulatory authorities. A minority of nonaccrual loans are consistent with the "doubtful" category. Loan interest receivable totaled $313 million and $261 million at December 31, 2023 and 2022, respectively, and was included in accrued income and other assets on the Consolidated Balance Sheets.

Foreclosed Properties Foreclosed properties were insignificant at December 31, 2023 and December 31, 2022. Retail loans secured by residential real estate properties in process of foreclosure included in nonaccrual loans were insignificant at December 31, 2023 and December 31, 2022. Loan Modifications Made to Borrowers Experiencing Financial Difficulty Effective January 1, 2023, the Corporation adopted the provisions of ASU 2022-02, which eliminated the accounting for TDRs while expanding loan modification and vintage disclosure requirements. The update specifically required additional disclosures on loan modifications to borrowers experiencing financial difficulties that involved an interest rate reduction, other-than-insignificant payment delay, a term extension, principal forgiveness or a combination thereof. The following table displays the amortized cost basis at December 31, 2023 of loan modifications made to borrowers experiencing financial difficulty that were restructured during the year ended December 31, 2023 by type of modification.

(a)Primarily loans secured by owner-occupied real estate. During the year ended December 31, 2023, mo difications to borrowers experiencing financial difficulty included restructurings with other-than-insignificant payment delays of $6 million in the Commercial loan category. On an ongoing basis, the Corporation monitors the performance of modified loans related to their restructured terms. Loans restructured during the year ended December 31, 2023 were current under modified terms at year ended December 31, 2023. Nonperforming restructured loans are classified as nonaccrual loans and are individually evaluated in the allowance for loan losses. For restructured loans, a subsequent payment default is defined in terms of delinquency, when a principal or interest payment is 90 days past due or classified into nonaccrual status during the reporting period. Of the loans restructured during the 12 month period ended December 31, 2023, there were no subsequent defaults as of December 31, 2023. Troubled Debt Restructurings Prior to the Adoption of ASU 2022-02 The following table details the amortized cost basis at December 31, 2022 of loans considered to be TDRs that were restructured during the year ended December 31, 2022 by type of modification. In cases of loans with more than one type of modification, the loans were categorized based on the most significant modification.

(a)Primarily represents loan balances where terms were extended by more than an insignificant time period, typically more than 180 days, at or above contractual interest rates. Also includes commercial loans restructured in bankruptcy. (b)Primarily loans secured by owner-occupied real estate. (c)Includes bankruptcy loans for which the court has discharged the borrower's obligation and the borrower has not reaffirmed the debt. The Corporation charges interest on principal balances outstanding during deferral periods. Additionally, none of the modifications involved forgiveness of principal. There were no significant commitments to lend additional funds to borrowers whose terms have been modified in TDRs at December 31, 2022. For principal deferrals, incremental deterioration in the credit quality of the loan, represented by a downgrade in the risk rating of the loan, for example, due to missed interest payments or a reduction of collateral value, was considered a subsequent default. For interest rate reductions, a subsequent payment default was defined in terms of delinquency, when a principal or interest payment was 90 days past due. Of the TDRs modified during the year ended December 31, 2022, there were $6 million of subsequent defaults of principal deferrals and no subsequent defaults of interest rate reductions.
