(1) We had 8 loans that were modified totaling $28.8 million under the CARES Act at December 31, 2021 compared to 52 loans that were modified totaling $195.6 million at December 31, 2020. These customers were not considered past due as a result of their delayed payments. Upon exiting the loan modification deferral program, the measurement of loan delinquency will resume where it left off upon entry into the program. Due to the modification program, this delinquency table may not accurately reflect the credit risk associated with these loans.
