There were no loan modifications during the three months ended September 30, 2021 that were classified as a troubled debt restructuring (TDR). There were two loan modifications during the three months ended September 30, 2020 that were classified as TDRs. These TDRs were a modification of the payment structure of residential mortgage loans with a recorded investment of $176,000 at the time of the modification. There was one loan modification during the nine months ended September 30, 2021 that was classified as a TDR. This TDR was a modification of the payment structure of a residential mortgage loan with a recorded investment of $4,000 at the time of the modification. There were three loan modifications during the nine months ended September 30, 2020 that were classified as TDRs. These TDRs were a modification of the payment structure of two residential mortgage loans with a recorded investment of $176,000 at the time of modification and an equity line with a recorded investment of $84,000 at the time of modification.

All TDRs are considered impaired loans and are individually evaluated in the determination of the allowance for loan losses. A TDR payment default occurs when, within 12 months of the original TDR modification, either a full or partial charge-off occurs or a TDR becomes 90 days or more past due. The specific reserve associated with a TDR is reevaluated when a TDR payment default occurs. There were no TDR payment defaults during the three and nine months ended September 30, 2021 and 2020.
