​ In the table above, outstanding loan balances are presented net of deferred loan origination fees, net, of $5,719,000 at September 30, 2021 and $6,286,000 at December 31, 2020. The Corporation grants loans to individuals as well as commercial and tax-exempt entities. Commercial, residential and personal loans are made to customers geographically concentrated in northcentral Pennsylvania, the southern tier of New York State, southeastern Pennsylvania and southcentral Pennsylvania. Although the Corporation has a diversified loan portfolio, a significant portion of its debtors’ ability to honor their contracts is dependent on the local economic conditions within the region. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was signed into law. The CARES Act is a $2 trillion stimulus package designed to provide relief to U.S. businesses and consumers struggling as a result of the pandemic. A provision in the CARES Act includes creation of the Paycheck Protection Program (“PPP”) through the Small Business Administration (“SBA”) and Treasury Department. Under the PPP, the Corporation, as an SBA-certified lender, provides SBA-guaranteed loans to small businesses to pay their employees, rent, mortgage interest, and utilities. PPP loans will be forgiven subject to clients’ providing documentation evidencing their compliant use of funds and otherwise complying with the terms of the program. Information related to PPP loans advanced pursuant to the CARES Act are labeled “1st Draw” within the tables. Section 4013 of the CARES Act provides that, from the period beginning March 1, 2020 until 60 days after the date on which the national emergency concerning the coronavirus (COVID-19) pandemic declared by the President of the United States under the National Emergencies Act terminates (the “applicable period”), the Corporation may elect to suspend U.S. GAAP for loan modifications related to the pandemic that would otherwise be categorized as troubled debt restructurings (TDRs) and suspend any determination of a loan modified as a result of the effects of the pandemic as being a TDR, including impairment for accounting purposes. The suspension is applicable for the term of the loan modification that occurs during the applicable period for a loan that was not more than 30 days past due as of December 31, 2019. The suspension is not applicable to any adverse impact on the credit of a borrower that is not related to the pandemic. In addition, the banking regulators and other financial regulators, on March 22, 2020 and revised April 7, 2020, issued a joint interagency statement titled the “Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus” that encourages financial institutions to work prudently with borrowers who are or may be unable to meet their contractual payment obligations due to the effects of the COVID-19 pandemic. Pursuant to the interagency statement, loan modifications that do not meet the conditions of Section 4013 of the CARES Act may still qualify as a modification that does not need to be accounted for as a TDR. Specifically, the agencies confirmed with the FASB staff that short-term modifications made in good faith in response to the pandemic to borrowers who were current prior to any relief are not TDRs under U.S. GAAP. This includes short-term (e.g. six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or delays in payment that are insignificant. Borrowers considered current are those that are less than 30 days past due on their contractual payments at the time a modification program is implemented. Appropriate allowances for loan and lease losses are expected to be maintained. With regard to loans not otherwise reportable as past due, financial institutions are not expected to designate loans with deferrals granted due to the pandemic as past due because of the deferral. The interagency statement also states that during short-term pandemic-related loan modifications, these loans generally should not be reported as nonaccrual. On December 27, 2020, the President of the United States signed into law the Consolidated Appropriations Act, 2021 (the “CAA”), which includes provisions that broadly address additional COVID-19 responses and relief. Among the additional relief measures included are certain extensions to elements of the CARES Act, including extension of temporary relief from troubled debt restructurings established under Section 4013 of the CARES Act to the earlier of a) January 1, 2022, or b) the date that is 60 days after the date on which the national COVID-19 emergency terminates. The CAA also includes additional funding for the PPP with additional eligibility requirements for borrowers with generally the same loan terms as provided under the CARES Act. Information related to PPP loans advanced pursuant to the CAA are labeled “2nd Draw” within the tables. The maximum term of PPP loans is five years. Most of the Corporation’s 1st Draw PPP loans have two-year terms, while 2nd Draw PPP loans have five-year terms and the Corporation will be repaid sooner to the extent the loans are forgiven. The interest rate on PPP loans is 1%, and the Corporation has received fees from the SBA ranging between 1% and 5% per loan, depending on the size of the loan. Fees on PPP loans, net of origination costs and a market rate adjustment on PPP loans acquired from Covenant, are recognized in interest income as a yield adjustment over the term of the loans. The Corporation began accepting and processing applications for loans under the PPP on April 3, 2020. Covenant also engaged in PPP lending starting in early April 2020. As of September 30, 2021, the recorded investment in 1st Draw PPP loans was $5,747,000, including contractual principal balances of $5,982,000, increased by a market rate adjustment on PPP loans acquired from Covenant of $2,000 and reduced by net deferred origination fees of $237,000. The recorded investment in 2nd Draw PPP loans was $56,981,000, including contractual principal balances of $59,190,000 reduced by net deferred origination fees of $2,208,000. Accretion of fees received on PPP loans, net of amortization of the market rate adjustment on PPP loans acquired from Covenant, was $1,409,000 in the three-month period ended September 30, 2021 and $467,000 in the three-month period ended September 30, 2020. Accretion of fees received on PPP loans, net of amortization of the market rate adjustment on PPP loans acquired from Covenant, was $3,975,000 in the nine-month period ended September 30, 2021 and $804,000 in the nine-month period ended September 30, 2020. ​ To work with clients impacted by COVID-19, the Corporation offers short-term loan modifications on a case-by-case basis to borrowers who were current in their payments at the inception of the loan modification program. Prior to the merger, Covenant had a similar program in place, and these modified loans have been incorporated into the Corporation’s program. These efforts have been designed to assist borrowers as they deal with the crisis and help the Corporation mitigate credit risk. For loans subject to the program, each borrower is required to resume making regularly scheduled loan payments at the end of the modification period and the deferred amounts will be moved to the end of the loan term. Consistent with Section 4013 of the CARES Act, the modified loans have not been reported as past due, nonaccrual or as TDRs at September 30, 2021. Most of the initial modifications under the program became effective in 2020 and provided a deferral of interest or principal and interest for 90-to-180 days. At September 30, 2021, there were no loans in deferral status under the program. At December 31, 2020, there were 45 loans with a total recorded investment of $37,397,000, in deferral status under the program. As described in Note 2, effective July 1, 2020, the Corporation acquired loans pursuant to its acquisition of Covenant, and effective April 1, 2019, the Corporation acquired loans pursuant to the acquisition of Monument Bancorp, Inc. (“Monument”). The acquired loans were recorded at their initial fair value, with adjustments made to the gross amortized cost of loans based on movements in interest rates (market rate adjustment) and based on credit fair value adjustments on non-impaired loans and impaired loans. Subsequent to the acquisitions, the Corporation has recognized amortization and accretion of a portion of the market rate adjustments and credit adjustments on non-impaired (performing) loans, and a partial recovery of purchased credit impaired (PCI) loans. For the three-month and nine-month periods ended September 30, 2021 and 2020, adjustments to the initial market rate and credit fair value adjustments of performing loans were recognized as follows: ​

​ The Corporation maintains an allowance for loan losses that represents management’s estimate of the losses inherent in the loan portfolio as of the balance sheet date and recorded as a reduction of the investment in loans. The allowance for loan losses is maintained at a level considered adequate to provide for losses that can be reasonably anticipated. Management performs a quarterly evaluation of the adequacy of the allowance. The allowance is based on the Corporation’s past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral, composition of the loan portfolio, current economic conditions and other relevant factors. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant revision as more information becomes available. In the process of evaluating the loan portfolio, management also considers the Corporation’s exposure to losses from unfunded loan commitments. As of September 30, 2021 and December 31, 2020, management determined that no allowance for credit losses related to unfunded loan commitments was required. Transactions within the allowance for loan losses, summarized by segment and class, for the three-month and nine-month periods ended September 30, 2021 and 2020 were as follows: ​

​ For the three months ended September 30, 2021, the provision for loan losses was $1,530,000, a decrease in expense of $411,000 as compared to $1,941,000 for the three months ended September 30, 2020. The third quarter 2021 provision included a net charge of $611,000 related to specific loans (net charge-offs of $1,205,000 offset by a net decrease in specific allowances on loans of $594,000), and an increase of $919,000 in the collectively determined portion of the allowance. In the third quarter 2021, the Corporation recorded a partial charge-off of $1,194,000 on a commercial loan with an outstanding balance of $3,496,000 at the time of the charge-off. The partial charge-off amount exceeded the specific allowance of $583,000 that had been established on this loan at June 30, 2021. The provision for loan losses in the third quarter 2020 included the net impact of a charge-off of $2,219,000 on a commercial loan of $3,500,000 for which the previously-established allowance had been $1,193,000. ​

​ ​ For the nine months ended September 30, 2021, the provision for loan losses was $2,533,000, a decrease in expense of $760,000 as compared to $3,293,000 recorded for the nine months ended September 30, 2020. The provision for the nine months ended September 30, 2021, includes the impact of a charge-off of $1,194,000 on a commercial loan with an ouststanding balance of $3,496,000, as previously discussed. In comparison, the provision for loan losses in the first nine months of 2020 included the impact of the $2,219,000 charge-off of a commercial loan of $3,500,000. In determining the larger loan relationships for detailed assessment under the specific allowance component, the Corporation uses an internal risk rating system. Under the risk rating system, the Corporation classifies problem or potential problem loans as “Special Mention,” “Substandard,” or “Doubtful” on the basis of currently existing facts, conditions and values. Substandard loans include those characterized by the distinct possibility that the Corporation will sustain some loss if the deficiencies are not corrected. Loans classified as Doubtful have all the weaknesses inherent in those classified as Substandard with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. Loans that do not currently expose the Corporation to sufficient risk to warrant classification as Substandard or Doubtful, but possess weaknesses that deserve management’s close attention, are deemed to be Special Mention. Risk ratings are updated any time that conditions or the situation warrants. Loans not classified are included in the “Pass” column in the table that follows. The following tables summarize the aggregate credit quality classification of outstanding loans by risk rating as of September 30, 2021 and December 31, 2020: ​

​ ​ In the table immediately above, loans to two borrowers are presented under the Residential mortgage loans – first liens and Residential mortgage loans – junior liens classes. Each of these loans is collateralized by one property, and the allowance associated with each of these loans was determined based on an analysis of the total amounts of the Corporation’s exposure in comparison to the estimated net proceeds if the Corporation were to sell the property. The total allowance related to these two borrowers was $139,000 at September 30, 2021 and $153,000 at December 31, 2020. The average balance of impaired loans, excluding purchased credit impaired loans, and interest income recognized on these impaired loans is as follows: ​
