Troubled Debt Restructurings: A modification of a loan may result in classification as a TDR when a borrower is experiencing financial difficulty and the modification constitutes a concession. The Corporation offers various types of modifications which may involve a change in the schedule of payments, a reduction in the interest rate, an extension of the maturity date, extending the maturity date at an interest rate lower than the current market rate for new debt with similar risk, requesting additional collateral, releasing collateral for consideration, substituting or adding a new borrower or guarantor, a permanent reduction of the recorded investment in the loan or a permanent reduction of the interest on the loan. Under Section 4013 of the CARES Act, loans less than 30 days past due as of December 31, 2019 will be considered current for COVID-19 related modifications and therefore will not be treated as TDRs. At its highest point as of May 31, 2020, in conformance with Section 4013 of the CARES Act, total loan forbearances represented 15.77% of the Corporation's total loan portfolio, or $242.5 million. As of September 30, 2021, 11 loans totaling $3.0 million remained in modified status, representing 0.20% of the Corporation's total loan portfolio, of which 5 loans totaling $2.9 million had been modified more than once. As of September 30, 2021 and December 31, 2020, the Corporation has a recorded investment in TDRs of $10.8 million and $6.7 million, respectively. There were specific reserves of $2.2 million and $0.4 million allocated for TDRs at September 30, 2021 and December 31, 2020, respectively. As of September 30, 2021, TDRs totaling $5.7 million were accruing interest under the modified terms and $5.1 million were on non-accrual status. As of December 31, 2020, TDRs totaling $2.8 million were accruing interest under the modified terms and $3.9 million were on non-accrual status. The Corporation has committed no additional amounts as of both September 30, 2021 and December 31, 2020, to customers with outstanding loans that are classified as TDRs. During the three months ended September 30, 2021, the terms and conditions of two commercial and industrial loans were modified as TDRs. The modification of the terms of both of these loans included a postponement or reduction of the scheduled amortized payments for greater than a three month period. During the three month period ended September 30, 2020, the terms of certain loans were modified as TDRs. During the three months ended September 30, 2020, the modification of terms of one residential mortgage loan included the postponement of scheduled amortized payments for a period greater than three-months. Additionally, two commercial and industrial loans were modified with the maturity date extended on both loans and one with an extension at a stated rate lower than the current market rate for new debt with similar risk. In addition to the modifications noted above, during the nine months ended September 30, 2021 the terms and conditions of two commercial and industrial loans and two commercial mortgage loans were modified as TDRs. The modification of the terms of all of these loans included a postponement or reduction of the scheduled amortized payments for greater than a three month period. In addition to the modifications noted above, during the nine month period ended September 30, 2020 modifications included two commercial and industrial loans where deferral of payments were granted and both loans were risk rated Substandard while one loan was in non-accrual status prior to the modification. The modifications of four commercial mortgage loans included the deferral of payments with three of the the loans risk rated Substandard and in non-accrual status, three of the borrowers were over one year past due in real estate taxes and two of the loans were over 30 days past due in payments. The modifications of three residential mortgages included the deferral of payments while all three were in non-accrual status prior to the modifications, two were risk rated Substandard and one was over thirty days past due in payments. The modifications of three home equity lines and loans included the deferral of payments while all three loans were risk rated Substandard and in non-accrual status prior to the modifications. The following table presents loans by class modified as TDRs that occurred during the three month period ended September 30, 2021 and September 30, 2020 (dollars in thousands):

The TDRs described above increased the allowance for loan losses by $1.9 million and resulted in no charge-offs during the nine month period ended September 30, 2021. The TDRs described above increased the allowance for loan losses by $0.1 million and resulted in no charge-offs during the nine month period ended September 30, 2020. A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms. There were no payment defaults on any loans previously modified as TDRs within twelve months following the modification during the three and nine month periods ended September 30, 2021 and 2020. Credit Quality Indicators The Corporation establishes a risk rating at origination for all commercial loans. The main factors considered in assigning risk ratings include, but are not limited to: historic and future debt service coverage, collateral position, operating performance, liquidity, leverage, payment history, management ability, and the customer’s industry. Commercial relationship managers monitor all loans in their respective portfolios for any changes in the borrower’s ability to service its debt and affirm the risk ratings for the loans at least annually. For the retail loans, which include residential mortgages, indirect and direct consumer loans, home equity lines and loans, and credit cards, once a loan is properly approved and closed, the Corporation evaluates credit quality based upon loan repayment. The Corporation uses the risk rating system to identify criticized and classified loans. Commercial relationships within the criticized and classified risk ratings are analyzed quarterly. The Corporation uses the following definitions for criticized and classified loans (which are consistent with regulatory guidelines): Special Mention – Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or the institution’s credit position at some future date. Substandard – Loans classified as substandard are inadequately protected by the current net worth and paying capability of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful – Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Commercial loans not meeting the criteria above to be considered criticized or classified are considered to be pass rated loans. Loans listed as not rated are included in groups of homogeneous loans performing under terms of the loan notes. Based on the analyses performed as of September 30, 2021 and December 31, 2020, the risk category of the recorded investment of loans by class of loans is as follows (in thousands):
