Loan modifications that were classified as TDRs, and the recorded investment in those loans at the time of their modification, during the years ended December 31, 2020 and 2019 and 2018 were as follows:


	Year Ended December 31,
	2020			2019			2018
	Number of	Recorded		Number of	Recorded		Number of	Recorded
(Dollars in thousands)	Loans	Investment		Loans	Investment		Loans	Investment

Equity lines	1		84	—		—	—		—
Consumer	—		—	1		121	1		5
Total	3	$	260	3	$	216	2	$	145

Each of the TDRs during the year ended December 31, 2020, two TDRs during the year ended December 31, 2019 and one during the year ended December 31, 2018 included modifications of the loan’s payment structure. One TDR during the year ended December 31, 2019 and one during the year ended December 31, 2018 included modifications of the loan’s interest rate. There were no TDRs in the years ended December 31, 2020, 2019 or 2018 that included a reduction in principal as part of the loan’s 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 years ended December 31, 2020, 2019 or 2018.

In response to the effects of the COVID-19 pandemic, including economic disruption and adverse impacts to commercial and consumer borrowers, the Bank has accommodated certain borrowers by granting short-term payment deferrals or periods of interest-only payments, which generally were less than six months for each borrower. Generally, a short-term payment deferral does not result in a loan modification being classified as a TDR. As of December 31, 2020, there were $30.74 million of loans whose modification periods had not ended or had been extended. Of these loans, $30.17 million were not required to be evaluated as TDRs as a result of the CARES Act.

Impaired loans, which included TDRs of $3.58 million, and the related allowance at December 31, 2020 were as follows:
