(a)Primarily loans secured by owner-occupied real estate. During the year ended December 31, 2024, mo difications to borrowers experiencing financial difficulty included restructurings with other-than-insignificant payment delays of $4 million in the Commercial category, $2 million in the International category and $3 million in the Home Equity category, compared to $6 million in the Commercial category at December 31, 2023. On an ongoing basis, the Corporation monitors the performance of modified loans related to their restructured terms. Of the loans restructured during the year, $10 million were past due at December 31, 2024 compared to all being current at 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, 2024, there were $13 million of Commercial loans that subsequently defaulted. There were no subsequent defaults as of December 31, 2023 of loans restructured during that 12 month period.
