Delinquent Loans

The following tables present the amortized cost, at the dates indicated, by class, of loans 30 to 89 days delinquent, loans 90 or more days delinquent or in foreclosure, total delinquent loans, current loans, and total loans. At December 31, 2023 and September 30, 2023, all loans 90 or more days delinquent were on nonaccrual status. The increase in correspondent and bulk purchased one- to four-family loans 30 to 89 days delinquent and in nonaccrual one- to four-family loans was due mainly to delinquencies returning to more historical levels as government payment assistance programs expired. The increase in commercial loans 30 to 89 days delinquent was a mix of several different borrowers and property types. There was not one underlying reason for the increase in commercial loan delinquencies from September 30, 2023. Management is working closely with the borrowers to address payment issues.
