SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2020
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 1 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The accounting policies of First Keystone Corporation and Subsidiary (the “Corporation”) are in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and conform to common practices within the banking industry. The more significant accounting policies follow: Principles of Consolidation The consolidated financial statements include the accounts of First Keystone Corporation and its wholly-owned subsidiary, First Keystone Community Bank (the “Bank”). All significant inter-company balances and transactions have been eliminated in consolidation. Nature of Operations The Corporation, headquartered in Berwick, Pennsylvania, provides a full range of banking, trust and related services through its wholly-owned Bank subsidiary and is subject to competition from other financial institutions in connection with these services. The Bank serves a customer base which includes individuals, businesses, governments, and public and institutional customers primarily located in the Northeast Region of Pennsylvania. The Bank has 18 full service offices, one loan production office, and 20 Automated Teller Machines (“ATM”) located in Columbia, Luzerne, Montour, Monroe, and Northampton counties. The Corporation must also adhere to certain federal and state banking laws and regulations and are subject to periodic examinations made by various state and federal agencies. Segment Reporting The Bank acts as an independent community financial services provider, and offers traditional banking and related financial services to individual, business, government, and public and institutional customers. Through its branch and ATM network, the Bank offers a full array of commercial and retail financial services, including the taking of time, savings and demand deposits; the making of commercial, consumer and mortgage loans; and the providing of other financial services. The Bank also performs personal, corporate, pension and fiduciary services through its Trust Department. Management does not separately allocate expenses, including the cost of funding loan demand, between the commercial, retail, trust and mortgage banking operations of the Corporation. As such, discrete financial information is not available and segment reporting would not be meaningful. Significant Concentrations of Credit Risk The majority of the Corporation’s activities involve customers located primarily in Columbia, Luzerne, Montour, Monroe, Northampton, and Lehigh counties in Pennsylvania. The types of securities in which the Corporation invests are presented in Note 3 – Securities. Credit risk as it relates to investment activities is moderated through the monitoring of ratings and geographic concentrations residing in the portfolio and the observance of minimum rating levels in the investment policy. Note 4 – Loans and Allowance for Loan Losses summarizes the types of lending in which the Corporation engages. The inherent risks associated with lending activities are mitigated by adhering to conservative underwriting practices and policies, as well as portfolio diversification and thorough monitoring of the loan portfolio. It is management’s opinion that the investment and loan portfolios were well balanced at December 31, 2020, to the extent necessary to avoid any significant concentrations of credit risk. Use of Estimates The preparation of these consolidated financial statements, in conformity with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of these consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant changes include the determination of other-than-temporary impairment on securities, the determination of the allowance for loan losses, and the assessment of goodwill for possible impairment. Subsequent Events The Corporation has evaluated events and transactions occurring subsequent to the consolidated balance sheet date of December 31, 2020, for items that should potentially be recognized or disclosed in the consolidated financial statements. The evaluation was conducted through the date these consolidated financial statements were issued. On February 23, 2021, the Board of Directors declared a dividend of $0.27 per share for the first quarter of 2021. The dividend is payable on March 31, 2021 to shareholders of record as of March 11, 2021. In addition, on February 23, 2021, the Board of Directors declared a special dividend of $0.01 per share for the first quarter of 2021. The special dividend is also payable on March 31, 2021 to shareholders of record as of March 11, 2021. Cash and Cash Equivalents For purposes of reporting consolidated cash flows, cash and cash equivalents include cash on hand and due from banks, interest-bearing deposits in other banks, and federal funds sold. The Corporation considers cash classified as interest-bearing deposits with other banks as a cash equivalent since they are represented by cash accounts essentially on a demand basis and mature within one year. Federal funds are also included as a cash equivalent because they are generally purchased and sold for one-day periods. Time Deposits with Other Banks Time deposits with other banks consist of fully insured certificates of deposit in other banks with maturity dates between one and five years. Securities The Corporation classifies its securities as either “Held-to-Maturity” or “Available-for-Sale” at the time of purchase. Securities are accounted for on a trade date basis. Debt securities are classified as Held-to-Maturity when the Corporation has the ability and positive intent to hold the securities to maturity. Securities classified as Held-to-Maturity are carried at cost adjusted for amortization of premium and accretion of discount to maturity. Debt securities not classified as Held-to-Maturity are included in the Available-for-Sale category and are carried at fair value. The amount of any unrealized gain or loss, net of the effect of deferred income taxes, is reported as accumulated other comprehensive income (AOCI) in the consolidated balance sheets and consolidated statements of changes in stockholders’ equity. Management’s decision to sell Available-for-Sale securities is based on changes in economic conditions controlling the sources and applications of funds, terms, availability of and yield of alternative investments, interest rate risk and the need for liquidity. The cost of debt securities classified as Held-to-Maturity or Available-for-Sale is adjusted for amortization of premiums to the earliest call date and accretion of discounts to expected maturity. Such amortization and accretion, as well as interest and dividends, are included in interest and dividend income on investment securities. Realized gains and losses are included in net investment securities gains and losses. The cost of securities sold, redeemed or matured is based on the specific identification method. Beginning January 1, 2018, upon adoption of Accounting Standard Update 2016-01, equity securities with readily determinable fair values are stated at fair value with realized and unrealized gains and losses reported in income. For periods prior to January 1, 2018, equity securities were classified as Available-for-Sale and stated at fair value with unrealized gains and losses reported as a separate component of AOCI, net of tax. Equity securities without readily determinable fair values are recorded at cost less impairment, if any. Management evaluates securities for other-than-temporary impairment (“OTTI”) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. Securities classified as Available-for-Sale or Held-to-Maturity are generally evaluated for OTTI under FASB ASC 320, Investments - Debt and Equity Securities When OTTI occurs on debt securities, the amount of the OTTI recognized in earnings depends on whether an entity intends to sell the security or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss. If an entity intends to sell or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss, the OTTI shall be recognized in earnings equal to the entire difference between the security’s amortized cost basis and its fair value at the balance sheet date. If an entity does not intend to sell the security and it is not more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis less any current-period loss, the OTTI shall be separated into the amount representing the credit loss and the amount related to all other factors. The amount of the total OTTI related to the credit loss is determined based on the present value of cash flows expected to be collected, and the realized loss is recognized as impairment charges on securities on the consolidated statements of income. The amount of the total OTTI related to the other factors shall be recognized in other comprehensive income (loss), net of applicable taxes. The previous amortized cost basis less the OTTI recognized in earnings becomes the new amortized cost basis of the security. The fair market value of the equity securities tends to fluctuate with the overall equity markets as well as the trends specific to each institution. The equity securities portfolio is reviewed in a similar manner as that of the debt securities with greater emphasis placed on the length of time the market value has been less than the carrying value and the financial sector outlook. The Corporation also reviews dividend payment activities, levels of non-performing assets and loan loss reserves. The starting point for the equity analysis is the length and severity of market value decline. The realized loss is recognized as impairment charges on securities on the consolidated statements of income. The previous cost basis less the OTTI recognized in earnings becomes the new cost basis of the investment. Restricted Investment in Bank Stocks The Bank owns restricted stock investments in the Federal Home Loan Bank of Pittsburgh (“FHLB-Pittsburgh”) and Atlantic Community Bankers Bank (“ACBB”). These investments do not have a readily determinable fair value because their ownership is restricted and they can be sold back only to the FHLB-Pittsburgh, ACBB or to another member institution. Therefore, these investments are carried at cost. At December 31, 2020, the Corporation held $2,212,000 in stock of FHLB-Pittsburgh and $35,000 in stock of ACBB. At December 31, 2019, the Corporation held $4,189,000 in stock of FHLB-Pittsburgh and $35,000 in stock of ACBB. Management evaluates the restricted investment in bank stocks for impairment on a quarterly basis. Management’s determination of whether these investments are impaired is based on management’s assessment of the ultimate recoverability of the cost of these investments rather than by recognizing temporary declines in value. The following factors were evaluated to determine the ultimate recoverability of the cost of the Corporation’s restricted investment in bank stocks; (i) the significance of the decline in net assets of the correspondent bank as compared to the capital stock amount for the correspondent bank and the length of time this situation has persisted; (ii) commitments by the correspondent bank to make payments required by law or regulation and the level of such payments in relation to the operating performance of the correspondent bank; (iii) the impact of legislative and regulatory changes on the institutions and, accordingly, on the customer base of the correspondent bank; and (iv) the liquidity position of the correspondent bank. Based on the analysis of these factors, management determined that no impairment charge was necessary related to the restricted investment in bank stocks during 2020 or 2019. Loans Net loans are stated at their outstanding recorded investment, net of deferred fees and costs, unearned income and the allowance for loan losses. Interest on loans is recognized as income over the term of each loan, generally, by the accrual method. Loan origination fees and certain direct loan origination costs have been deferred with the net amount amortized using the straight line method or the interest method over the contractual life of the related loans as an interest yield adjustment. The loans receivable portfolio is segmented into commercial, residential and consumer loans. Commercial loans consist of the following classes: Commercial and Industrial and Commercial Real Estate. Commercial and Industrial Lending The Corporation originates commercial and industrial loans primarily to businesses located in its primary market area and surrounding areas. These loans are used for various business purposes, which include short-term loans and lines of credit to finance machinery and equipment, inventory and accounts receivable. Generally, the maximum term for loans extended on machinery and equipment is based on the projected useful life of such machinery and equipment. Most business lines of credit are written on demand and are reviewed annually. Commercial and industrial loans are generally secured with short-term assets; however, in many cases, additional collateral such as real estate is provided as additional security for the loan. Loan-to-value maximum thresholds have been established by the Corporation and are specific to the type of collateral. Collateral values may be determined using invoices, inventory reports, accounts receivable aging reports, business financial statements, collateral appraisals or internal evaluations, etc. Commercial and industrial loans are typically supported by personal guarantees of the borrower. In underwriting commercial and industrial loans, an analysis is performed to evaluate the borrower’s character and capacity to repay the loan, the adequacy of the borrower’s capital and collateral, as well as the conditions affecting the borrower. Evaluation of the borrower’s past, present and future cash flows is also an important aspect of the Corporation’s analysis of the borrower’s ability to repay. Commercial and industrial loans generally present a higher level of risk than other types of loans due primarily to the effect of general economic conditions. Commercial and industrial loans are typically made on the basis of the borrower’s ability to make repayment from cash flows from the borrower’s primary business activities. As a result, the availability of funds for the repayment of commercial and industrial loans is dependent on the success of the business itself, which in turn, is likely to be dependent upon the general economic environment. As an addition to the commercial loans receivable portfolio, the Corporation may purchase the guaranteed portion of loans secured by the U.S. Government. The originating bank retains the unguaranteed portion of the loan. The loans are sponsored by one of the various government agencies including the U.S. Small Business Administration, United States Department of Agriculture (“USDA”), and the Farm Service Agency (“FSA”). Government Guaranteed Loans ("GGLs") carry no credit risk due to an unconditional and irrevocable guarantee (which is supported by the full faith and credit of the U.S. Government) on all principal and the balance of interest accruing through ninety days beyond the date that demand is made to the originating bank for repurchase of the loan. As of December 31, 2020, the Corporation's balance of GGLs amounted to $5,128,000, compared to $6,150,000 at December 31, 2019. Commercial Real Estate Lending The Corporation engages in commercial real estate lending in its primary market area and surrounding areas. The Corporation’s commercial real estate portfolio is secured primarily by commercial retail space, commercial office buildings, residential housing and hotels. Generally, commercial real estate loans have terms that do not exceed twenty years In underwriting these loans, the Corporation performs a thorough analysis of the financial condition of the borrower, the borrower’s credit history, and the reliability and predictability of the cash flow generated by the property securing the loan. The value of the property is determined by either independent appraisers or internal evaluations performed by Bank officers. Commercial real estate loans generally present a higher level of risk than residential real estate secured loans. Repayment of loans secured by commercial real estate is typically dependent upon the successful operation of the related real estate project and/or the effect of the general economic conditions on income producing properties. Residential Real Estate Lending (Including Home Equity) The Corporation’s residential real estate portfolio is comprised of one-to-four family residential mortgage loan originations, home equity term loans and home equity lines of credit. These loans are generated by the Corporation’s marketing efforts, its present customers, walk-in customers and referrals. These loans originate primarily within or with customers from the Corporation’s market area. The Corporation’s one-to-four family residential mortgage originations are secured primarily by properties located in its primary market area and surrounding areas. The Corporation offers fixed-rate mortgage loans with terms up to a maximum of thirty years for both permanent structures and those under construction. Loans with terms of thirty years are normally held for sale and sold without recourse; most of the residential mortgages held in the Corporation’s residential real estate portfolio have maximum terms of twenty years. Generally, the majority of the Corporation’s residential mortgage loans originate with a loan-to-value of eighty percent or less, or those with primary mortgage insurance at ninety-five percent or less. Home equity term loans are secured by the borrower’s primary residence and typically have a maximum loan-to-value of eighty percent and a maximum term of fifteen years. In general, home equity lines of credit are secured by the borrower’s primary residence with a maximum loan-to-value of eighty percent and a maximum term of twenty years. In underwriting one-to-four family residential mortgage loans, the Corporation evaluates the borrower’s ability to make monthly payments, the borrower’s prior loan repayment history and the value of the property securing the loan. The ability and willingness to repay is assessed based upon the borrower’s employment history, current financial conditions and credit background. A majority of the properties securing residential real estate loans made by the Corporation are appraised by independent appraisers. The Corporation generally requires mortgage loan borrowers to obtain an attorney’s title opinion or title insurance and fire and property insurance, including flood insurance, if applicable. Residential mortgage loans, home equity term loans and home equity lines of credit generally present a lower level of risk than consumer loans because they are secured by the borrower’s primary residence. Risk is increased when the Corporation is in a subordinate position, especially to another lender, for the loan collateral. Residential mortgage loans held for sale are carried at the lower of cost or market on an aggregate basis determined by independent pricing from appropriate federal or state agency investors. These loans are sold without recourse. Loans held for sale amounted to $17,300,000 at December 31, 2020 and $2,292,000 at December 31, 2019. Consumer Lending The Corporation offers a variety of secured and unsecured consumer loans, including vehicle loans, stock loans and loans secured by financial institution deposits. These loans originate primarily within or with customers from the Corporation’s market area. Consumer loan terms vary according to the type and value of collateral and creditworthiness of the borrower. In underwriting personal loans, a thorough analysis is performed regarding the borrower’s willingness and financial ability to repay the loan as agreed. The ability and willingness to repay is assessed based upon the borrower’s employment history, current financial condition and credit background. Consumer loans may entail greater credit risk than residential real estate loans, particularly in the case of personal loans which are unsecured or are secured by rapidly depreciable assets, such as automobiles or recreational equipment. In such cases, repossessed collateral for a defaulted personal loan may not provide an adequate source of repayment of the outstanding loan balance as a result of the greater likelihood of damage, loss or depreciation. In addition, personal loan collections are dependent on the borrower’s continuing financial stability and therefore, are more likely to be affected by adverse personal circumstances. Furthermore, the application of various federal and state laws, including bankruptcy and insolvency laws, may limit the amount which can be recovered on such loans. Coronavirus Pandemic Impact on the Loan Portfolio As a result of the economic impact of the COVID-19 coronavirus pandemic, the Coronavirus Aid Relief, and Economic Security (“CARES”) Act was enacted in the United States on March 27, 2020. The Corporation is approved by the SBA to fund loans under the SBA’s Paycheck Protection Program (“PPP”) created as part of the CARES Act. The PPP loans have 1.00% interest rates, lender fees, two or five-year terms (depending on date of origination), and may qualify for forgiveness. These loans funded by the Corporation are subject to the terms and conditions applicable to all loans made pursuant to the PPP, as administered by the SBA under the CARES Act. The Paycheck Protection Program calls for these loans to be fully guaranteed by the SBA. PPP loan origination fees and certain loan origination costs have been deferred with the net amount accreted using the straight line method over the contractual life of the related loans as an interest yield adjustment. If a loan is forgiven pursuant to the terms and conditions applicable to the PPP, the remaining origination fees and costs are recognized at the time of forgiveness. All PPP loans are carried in the Corporation’s Commercial and Industrial loan portfolio. As of December 31, 2020, the Corporation held 441 PPP loans in its Commercial and Industrial portfolio, which carried a balance of $22,976,000. An additional provision of the CARES Act, Section 4013 provides financial institutions the option to suspend requirements to categorize certain loan modifications as troubled debt restructurings, as long as specific criteria are met. To qualify, the loan modifications must be made on a good-faith basis in response to the COVID-19 pandemic, must occur between March 1, 2020 and the earlier of June 30, 2021 or the termination date of the national emergency related to the COVID-19 pandemic as declared by the President of the United States, and the loans must have been paid current (less than 30 days past due prior to any relief) as of December 31, 2019. In compliance with Section 4013 of the CARES Act, the Corporation has granted modification requests to defer principal and/or interest payments or modify interest rates on various loans across all portfolio segments. Of the loan modifications that have been granted in compliance with Section 4013 of the CARES Act, there were 44 loan modifications still actively on deferral carrying an aggregate balance of $16,541,000 as of December 31, 2020. See page 78 for additional information regarding the Section 4013 CARES Act modifications. Delinquent Loans Generally, a loan is considered to be past-due when scheduled loan payments are in arrears 10 days or more. Delinquent notices are generated automatically when a loan is 10 or 15 days past-due, depending on loan type. Collection efforts continue on past-due loans that have not been brought current, when it is believed that some chance exists for improvement in the status of the loan. Past-due loans are continually evaluated with the determination for charge-off being made when no reasonable chance remains that the status of the loan can be improved. Commercial and Industrial and Commercial Real Estate loans are charged off in whole or in part when they become sufficiently delinquent based upon the terms of the underlying loan contract and when a collateral deficiency exists. Because all or part of the contractual cash flows are not expected to be collected, the loan is considered to be impaired, and the Corporation estimates the impairment based on its analysis of the cash flows or collateral estimated at fair value less cost to sell. Should a Government Guaranteed Loan default, demand is made to the originating bank for repurchase of the loan. If the originating bank does not repurchase the loan, demand for repurchase is then made to the appropriate government agency which has provided the guarantee for the loan. Residential Real Estate and Consumer loans are charged off when they become sufficiently delinquent based upon the terms of the underlying loan contract and when the value of the underlying collateral is not sufficient to support the loan balance and a loss is expected. At that time, the amount of estimated collateral deficiency, if any, is charged off for loans secured by collateral, and all other loans are charged off in full. Loans with collateral are written down to the estimated fair value of the collateral less cost to sell. Existing loans in which the borrower has declared bankruptcy are considered on a case by case basis to determine whether repayment is likely to occur (eg. reaffirmation by the borrower with demonstrated repayment ability). Otherwise, loans are charged off in full or written down to the estimated fair value of collateral less cost to sell. Generally, a loan is classified as non-accrual and the accrual of interest on such a loan is discontinued when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about further collectability of principal or interest, even though the loan may currently be performing. A loan may remain on accrual status if it is well secured (or supported by a strong guarantee) and in the process of collection. When a loan is placed on non-accrual status, unpaid interest credited to income in the current year is reversed and unpaid interest accrued in prior years is charged against interest income. Certain non-accrual loans may continue to perform; that is, payments are still being received. Generally, the payments are applied to principal. These loans remain under constant scrutiny, and if performance continues, interest income may be recorded on a cash basis based on management’s judgment regarding the collectability of principal. Allowance for Loan Losses The allowance for loan losses is established through provisions for loan losses charged against income. Loans deemed to be uncollectible are charged against the allowance for loan losses and subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is maintained at a level estimated by management to be adequate to absorb potential loan losses. Management’s periodic evaluation of the adequacy of the allowance for loan losses 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 (including the timing of future payments), 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 including the amounts and timing of future cash flows expected to be received on impaired loans that may be susceptible to significant change. The allowance consists of specific, general and unallocated components. The specific component relates to loans that are individually classified as impaired. Select loans are not aggregated for collective impairment evaluation, as such; all loans are subject to individual impairment evaluation should the facts and circumstances pertinent to a particular loan suggest that such evaluation is necessary. Factors considered by management in determining impairment include payment status and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. If a loan is impaired, a portion of the allowance may be allocated so that the loan is reported, net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from collateral. Troubled debt restructurings are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using the loan’s effective rate at inception. If a troubled debt restructuring is considered to be a collateral dependent loan, the loan may be reported, net, at the fair value of the collateral. For troubled debt restructurings that subsequently default, the Corporation determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses. The general component covers all other loans not identified as impaired (aside from GGLs, which do not require an allowance) and is based on historical losses and qualitative factors. The historical loss component of the allowance is determined by losses recognized by portfolio segment over a time period that management has determined represents the current credit cycle. Qualitative factors impacting each portfolio segment may include: delinquency trends, loan volume trends, Bank policy changes, management processes and oversight, economic trends (including change in consumer and business disposable incomes, unemployment and under-employment levels, and other conditions), concentrations by industry or product, internal and external loan review processes, collateral value and market conditions, and external factors including regulatory issues and competition. In response to the COVID-19 pandemic and its impact on the current economy, the qualitative factors related to the local/regional economy were increased by two basis points across all loan segments during the first quarter of 2020, and increased by an additional basis point across all loan segments during the second quarter of 2020. The qualitative factor relating to the impact of external factors/conditions for the Commercial Real Estate portfolio segment was increased by an additional basis point during the third quarter of 2020. The qualitative factors relating to the impact of external factors/conditions were increased by two additional basis points across all loan segments during the fourth quarter of 2020. Modifications granted in compliance with Section 4013 of the CARES Act are highest in the Commercial Real Estate portfolio segment, the long-term effects of which are still very unclear, as there is still economic uncertainty related to the COVID-19 pandemic, especially in relation to this segment of the Corporation’s loan portfolio. Government Guaranteed Loans do not require an associated allowance for loan losses due to the underlying irrevocable and unconditional guarantee, which is supported by the full faith and credit of the U.S. Government. Should a GGL default, the loan will be repurchased by the originating bank or the appropriate government agency that has provided the guarantee for the loan. Although PPP loans do not require an associated allowance for loan losses due to the program’s call for a full guarantee by the SBA, the Corporation has taken the conservative approach and has calculated a

RESTRICTED CASH BALANCES	NOTE 2 — RESTRICTED CASH BALANCES The Bank was previously required to maintain certain average reserve balances as established by the Federal Reserve Board. The amount of the reserve balance for the reserve computation period, which included December 31, 2019, was $1,352,000 , which was satisfied through the restriction of vault cash. Effective March 26, 2020, the average cash reserve requirement was suspended, as the Federal Reserve Board reduced reserve requirement ratios to zero percent in response to the COVID-19 pandemic in order to support the flow of credit to households and businesses. The Bank maintains a clearing balance at the Federal Reserve Bank to offset daily cash management activities and specific charges for services. At December 31, 2020 and 2019, the amount of this balance was $15,251,000 and $463,000, respectively.

The mortgage backed securities are issued by FHLMC (“Federal Home Loan Mortgage Corporation”), FNMA (“Federal National Mortgage Association”) or GNMA (“Government National Mortgage Association”). The municipal securities consist of general obligations and revenue bonds. The fair market value of the above securities is influenced by market interest rates, prepayment speeds on mortgage securities, bid-offer spreads in the market place and credit premiums for various types of agency debt. These factors change continuously and therefore the market value of these securities may be higher or lower than the Corporation’s carrying value at any measurement date. Management does not believe any of their 14 debt securities with a less than one year unrealized loss position, or any of their 17 debt securities with a one year or greater unrealized loss position, as of December 31, 2020, represent an other-than-temporary impairment, as these unrealized losses relate principally to changes in interest rates subsequent to the acquisition of the specific securities. The Corporation expects to collect all principal and interest payments defined under the original terms as all contracted payments on securities in the portfolio are current as of December 31, 2020.

SHORT-TERM BORROWINGS	NOTE 7 — SHORT-TERM BORROWINGS Short-term borrowings include federal funds purchased, securities sold under agreements to repurchase, Federal Discount Window, and FHLB advances, which generally represent overnight or less than 30 -day borrowings. Short-term borrowings and weighted-average interest rates at and for the years ended December 31, 2020 and 2019 are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (Dollars in thousands) ​ 2020 ​ ​ 2019 ​ ​ ​ ​ ​ Average ​ ​ ​ ​ ​ Average ​ Amount Rate ​ Amount Rate Federal funds purchased $ — ​ 0.37 % ​ $ — 2.01 % Securities sold under agreements to repurchase ​ 19,494 ​ 0.58 % ​ 14,042 1.03 % Federal Discount Window ​ — ​ 0.37 % ​ — 2.92 % Federal Home Loan Bank of Pittsburgh ​ — ​ 1.00 % ​ 40,621 2.59 % ​ ​ $ 19,494 ​ 0.82 % ​ $ 54,663 2.37 % ​ At December 31, 2020, the maximum borrowing capacity of federal funds purchased and the Federal Discount Window was $15,000,000 and $4,215,000, respectively. Please refer to Note 8 ― Long-Term Borrowings for the Corporation’s maximum borrowing capacity at FHLB. Securities Sold Under Agreements to Repurchase (“Repurchase Agreements”) The Corporation enters into agreements under which it sells securities subject to an obligation to repurchase the same or similar securities. Under these arrangements, the Corporation may transfer legal control over the assets but still retain effective control through an agreement that both entitles and obligates the Corporation to repurchase the assets. As a result, these repurchase agreements are accounted for as collateralized financing agreements (i.e., secured borrowings) and not as a sale and subsequent repurchase of securities. The obligation to repurchase the securities is reflected as a liability on the Corporation’s consolidated balance sheets, while the securities underlying the repurchase agreements remain in the respective investment securities asset accounts. In other words, there is not offsetting or netting of the investment securities assets with the repurchase agreement liabilities. In addition, as the Corporation does not enter into reverse repurchase agreements, there is no such offsetting to be done with the repurchase agreements. The right of setoff for a repurchase agreement resembles a secured borrowing, whereby the collateral would be used to settle the fair value of the repurchase agreement should the Corporation be in default (e.g., fails to make an interest payment to the counterparty). The collateral is held by a correspondent bank in the counterparty’s custodial account. The counterparty has the right to sell or repledge the investment securities. ​ ​ ​ ​ ​ ​ ​ The following table presents the short-term borrowings subject to an enforceable master netting arrangement or repurchase agreements as of December 31, 2020 and 2019. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (Dollars in thousands) ​ ​ Gross Net Amounts ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amounts ​ of Liabilities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Offset ​ Presented ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gross ​ in the ​ in the ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amounts of ​ Consolidated ​ Consolidated ​ ​ ​ ​ Cash ​ ​ ​ ​ ​ Recognized ​ Balance ​ Balance ​ Financial ​ Collateral ​ Net ​ ​ Liabilities ​ Sheet ​ Sheet ​ Instruments ​ Pledge ​ Amount December 31, 2020 ​ ​ ​ ​ ​ ​ Repurchase agreements (a) ​ $ 19,494 ​ $ — ​ $ 19,494 ​ $ (19,494) ​ $ — ​ $ — ​ ​ ​ ​ ​ ​ ​ December 31, 2019 ​ ​ ​ ​ ​ ​ Repurchase agreements (a) ​ $ 14,042 ​ $ — ​ $ 14,042 ​ $ (14,042) ​ $ — ​ $ — (a) As of December 31, 2020 and 2019, the fair value of securities pledged in connection with repurchase agreements was $23,695,000 and $22,413,000 , respectively .

SUBORDINATED DEBENTURES	NOTE 9 — SUBORDINATED DEBENTURES On December 10, 2020, the Corporation issued $25,000,000 aggregate principal amount of Subordinated Notes due 2030 (the “2020 Notes”) to accredited investors. The 2020 Notes are intended to be treated as Tier 2 capital for regulatory capital purposes. The 2020 Notes bear a fixed interest rate of 4.375% per year for the first five years and then float based on a benchmark rate (as defined). Interest will be payable semi-annually in arrears on June 30 and December 31 of each year, beginning on June 30, 2021, for the first five years after issuance and will be payable quarterly in arrears thereafter on March 31, June 30, September 30 and December 31.

The valuation allowance relates to state net operating loss carryforwards for which realizability is uncertain. At December 31, 2020 and 2019, the Corporation had state net operating loss carryforwards, net of a valuation allowance, of $0, which are available to offset future state taxable income, and expire at various dates through 2040 In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. Based on the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible and tax planning strategies, management believes it is more likely than not that the Corporation will realize the benefits of these deferred tax assets, net of any valuation allowance at December 31, 2020. The Corporation did not have any uncertain tax positions at December 31, 2020 and 2019. The Corporation and its subsidiary file a consolidated federal income tax return. The Corporation is no longer subject to examination by Federal or State taxing authorities for the years before 2017.

EMPLOYEE BENEFIT PLANS AND DEFERRED COMPENSATION AGREEMENTS
EMPLOYEE BENEFIT PLANS AND DEFERRED COMPENSATION AGREEMENTS	NOTE 11 — EMPLOYEE BENEFIT PLANS AND DEFERRED COMPENSATION AGREEMENTS The Corporation maintains a 401k Plan which has a combined tax qualified savings feature and profit sharing feature for the benefit of its employees. Effective January 1, 2014, the plan became a Safe Harbor Plan. Under the savings feature, the Corporation makes safe harbor matching contributions of 100% of the first 3% of compensation an employee contributes to the Plan and 50% of the next 2% of compensation an employee contributes to the Plan. The safe harbor matching contributions amounted to $330,000 and $309,000 in 2020 and 2019, respectively. Under the profit sharing feature, contributions, at the discretion of the Board of Directors, are funded currently and amounted to $455,000 and $329,000 in 2020 and 2019, respectively. The Corporation also has non-qualified deferred compensation agreements with one of its current officers and five retired officers. These agreements are essentially unsecured promises by the Corporation to make monthly payments to the officers over fifteen or twenty year periods. Payments begin based upon specific criteria — generally, when the officer retires. To account for the cost of payments yet to be made in the future, the Corporation recognizes an accrued liability in years prior to when payments begin based on the present value of those future payments. The Corporation’s accrued liability for these deferred compensation agreements, reported in other liabilities on the consolidated balance sheets, as of December 31, 2020 and 2019, was $995,000 and $1,056,000, respectively. The related expense for these agreements, reported in salaries and employee benefits on the consolidated statements of income, amounted to $70,000 and $73,000 in 2020 and 2019, respectively.

COMMITMENTS AND CONTINGENCIES
COMMITMENTS AND CONTINGENCIES	NOTE 12 — COMMITMENTS AND CONTINGENCIES In the normal course of business, there are various pending legal actions and proceedings that are not reflected in the consolidated financial statements. Management does not believe the outcome of these actions and proceedings will have a material effect on the consolidated financial position of the Corporation. The Corporation currently leases three branch banking facilities and one parcel of land under operating leases. At December 31, 2020, right-of-use assets and lease liabilities were recorded related to these operating leases totaling $1,061,000 and $1,513,000, respectively. Further options to extend or terminate the leases are not applicable for any of the four leases. No significant assumptions or judgements were made in determining whether a contract contained a lease or in the consideration of lease versus non-lease components. None of the leases contained an implicit rate; therefore, our incremental borrowing rate was used for each of the leases. The Corporation recognized total operating lease costs for the years ended December 31, 2020 and 2019 of $413,000 and $257,000, respectively. Cash payments totaled $154,000 and $156,000 for the years ended December 31, 2020 and 2019, respectively. The Corporation currently has three finance leases for equipment. At December 31, 2020, right-of-use assets and lease liabilities were recorded related to these finance leases totaling $94,000 and $84,000, respectively. Amounts recognized as right-of-use assets related to finance leases are included in Premises and equipment, net in the accompanying balance sheet. Further options to extend or terminate the lease are not applicable for any of the three leases. No significant assumptions or judgements were made in determining whether a contract contained a lease or in the consideration of lease versus non-lease components. None of the leases contained an implicit rate; therefore, our incremental borrowing rate was used for each of the leases. Total finance lease costs that were recognized by the Corporation for the year ended December 31, 2020 were immaterial. Cash payments totaled $4,000.

The loans do not involve more than the normal risk of collectability nor present other unfavorable features. A summary of the activity on the related party loans consists of the following: (Dollars in thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ 2020 2019 Balance at January 1 $ 16,240 ​ $ 19,948 Additions ​ 11,108 ​ 4,139 Deductions ​ (12,524) ​ (7,847) Balance at December 31 ​ $ 14,824 ​ $ 16,240 ​ The summary of activity on the related party loans represent funds drawn and outstanding at the date of the consolidated financial statements.

Deposits from certain officers, directors and immediate family members and/or their related companies held by the Bank amounted to $25,332,000 and $21,140,000 at December 31, 2020 and 2019, respectively.

REGULATORY MATTERS

REGULATORY MATTERS
REGULATORY MATTERS	NOTE 14 — REGULATORY MATTERS Under Pennsylvania banking law, the Bank is subject to certain restrictions on the amount of dividends that it may declare without prior regulatory approval. At December 31, 2020, $13,179,000 of retained earnings were available for dividends without prior regulatory approval, subject to the regulatory capital requirements discussed below. Regulations also limit the amount of loans and advances from the Bank to the Corporation to 10% of consolidated net assets. The Corporation is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory — and possibly additional discretionary — actions by regulators that, if undertaken, could have a direct material effect on the Corporation’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Corporation must meet specific capital guidelines that involve quantitative measures of the Corporation’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Corporation’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Management believes, as of December 31, 2020 and 2019, that the Corporation and the Bank met all capital adequacy requirements to which they are subject. On July 2, 2013, the Board of Governors of the Federal Reserve System finalized its rule implementing the Basel III regulatory capital framework, which the FDIC adopted on July 9, 2013. Under the rule, minimum requirements increased both the quantity and quality of capital held by banking organizations. Consistent with the Basel III framework, the rule included a new minimum ratio of common equity tier 1 capital to risk-weighted assets of 4.5 percent, and a common equity tier 1 conservation buffer of 2.5 percent of risk-weighted assets, that applies to all supervised financial institutions, which was phased in over a three year period beginning January 1, 2016, with the full 2.5 percent required as of January 1, 2019. The rule also raised the minimum ratio of tier 1 capital to risk-weighted assets from 4 percent to 6 percent, and includes a minimum leverage ratio of 4 percent for all banking organizations. Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the table below) of total capital, tier I capital and common equity tier 1 capital (as defined in the regulations) to risk weighted assets (as defined), and of tier I capital (as defined) to average assets (as defined). As of December 31, 2020 the most recent notification from the Federal Deposit Insurance Corporation categorized the Bank as Well Capitalized under the regulatory framework for prompt corrective action. To be categorized as Well Capitalized, the Bank must maintain minimum total risk-based, tier I risk-based, common equity tier 1 risk-based and tier I leverage ratios as set forth in the table. There are no conditions or events since the notification that management believes have changed the Bank’s category. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (Dollars in thousands) ​ ​ ​ ​ ​ ​ ​ For Capital ​ ​ Minimum Capital ​ ​ To Be Well Capitalized ​ ​ ​ ​ ​ ​ ​ ​ Adequacy ​ ​ Adequacy with ​ ​ Under Prompt Corrective ​ ​ Actual ​ ​ Purposes ​ ​ Capital Buffer ​ ​ Action Provisions ​ Amount Ratio ​ Amount Ratio ​ Amount Ratio ​ Amount Ratio As of December 31, 2020: ​ ​ ​ ​ ​ ​ ​ ​ Total Capital (to Risk-Weighted Assets) ​ $ 129,704 17.05 % ​ $ 60,842 8.00 % ​ $ 79,856 10.50 % ​ $ 76,053 10.00 % Tier I Capital (to Risk-Weighted Assets) ​ $ 121,642 15.99 % ​ $ 45,632 6.00 % ​ $ 64,645 8.50 % ​ $ 60,842 8.00 % Common Equity Tier 1 Capital (to Risk-Weighted Assets) ​ $ 121,642 15.99 % ​ $ 34,224 4.50 % ​ $ 53,237 7.00 % ​ $ 49,434 6.50 % Tier I Capital (to Average Assets) ​ $ 121,642 10.81 % ​ $ 45,006 4.00 % ​ $ 45,006 4.00 % ​ $ 56,258 5.00 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (Dollars in thousands) ​ ​ ​ ​ ​ ​ ​ For Capital ​ ​ Minimum Capital ​ ​ To Be Well Capitalized ​ ​ ​ ​ ​ ​ ​ ​ Adequacy ​ ​ Adequacy with ​ ​ Under Prompt Corrective ​ ​ Actual ​ ​ Purposes ​ ​ Capital Buffer ​ ​ Action Provisions ​ Amount Ratio ​ Amount Ratio ​ Amount Ratio ​ Amount Ratio As of December 31, 2019: ​ ​ ​ ​ ​ ​ ​ ​ Total Capital (to Risk-Weighted Assets) ​ $ 100,193 14.53 % ​ $ 55,168 8.00 % ​ $ 72,409 10.50 % ​ $ 68,961 10.00 % Tier I Capital (to Risk-Weighted Assets) ​ $ 93,063 13.50 % ​ $ 41,376 6.00 % ​ $ 58,617 8.50 % ​ $ 55,168 8.00 % Common Equity Tier 1 Capital (to Risk-Weighted Assets) ​ $ 93,063 13.50 % ​ $ 31,032 4.50 % ​ $ 48,272 7.00 % ​ $ 44,824 6.50 % Tier I Capital (to Average Assets) ​ $ 93,063 9.42 % ​ $ 39,531 4.00 % ​ $ 39,531 4.00 % ​ $ 49,414 5.00 % ​ The capital conservation buffer phase-in began January 1, 2016.

FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK AND CONCENTRATIONS OF CREDIT RISK
FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK AND CONCENTRATIONS OF CREDIT RISK	NOTE 15 — FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK AND CONCENTRATIONS OF CREDIT RISK Financial Instruments with Off-Balance Sheet Risk The Corporation is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets. The contract or notional amounts of those instruments reflect the extent of involvement the Corporation has in particular classes of financial instruments. The Corporation does not engage in trading activities with respect to any of its financial instruments with off-balance sheet risk. The Corporation’s exposure to credit loss in the event of non-performance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments. The Corporation uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The Corporation may require collateral or other security to support financial instruments with off-balance sheet credit risk. The contract or notional amounts at December 31, 2020 and 2019 were as follows: ​ ​ ​ ​ ​ ​ ​ (Dollars in thousands) ​ ​ ​ ​ ​ ​ ​ 2020 2019 Financial instruments whose contract amounts represent credit risk: ​ ​ Commitments to extend credit ​ $ 114,836 ​ $ 122,082 Financial standby letters of credit ​ $ 1,175 ​ $ 335 Performance standby letters of credit ​ $ 3,448 ​ $ 3,230 ​ Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses that may require payment of a fee. Since some of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Corporation evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Corporation upon extension of credit, is based on management’s credit evaluation of the borrower. Collateral held varies but may include accounts receivable, inventory, property, plant and equipment, owner-occupied income-producing commercial properties, and residential real estate. Standby letters of credit are conditional commitments issued by the Corporation to guarantee payment to a third party when a customer either fails to repay an obligation or fails to perform some non-financial obligation. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Corporation may hold collateral (similar to the items held as collateral for commitments to extend credit) to support standby letters of credit for which collateral is deemed necessary. Financial Instruments with Concentrations of Credit Risk The Corporation originates primarily commercial and residential real estate loans to customers in northeastern Pennsylvania. The ability of the majority of the Corporation’s customers to honor their contractual loan obligations is dependent on the economy and real estate market in this area. At December 31, 2020, the Corporation had $623,711,000 in loans secured by real estate, which represented 86.6% of total loans. The real estate loan portfolio is largely secured by lessors of residential buildings and dwellings, lessors of non-residential buildings, and lessors of hotels/motels. As of December 31, 2020 and 2019, management is of the opinion that there were no concentrations exceeding 10% of total loans with regard to loans to borrowers who were engaged in similar activities that were similarly impacted by economic or other conditions. As all financial instruments are subject to some level of credit risk, the Corporation requires collateral and/or guarantees for all loans. Collateral may include, but is not limited to property, plant, and equipment, commercial and/or residential real estate property, land, and pledge of securities. In the event of a borrower’s default, the collateral supporting the loan may be seized in order to recoup losses associated with the loan. The Corporation also establishes an allowance for loan losses that constitutes the amount available to absorb losses within the loan portfolio that may exist due to deficiencies in collateral values.

STOCKHOLDERS' EQUITY	NOTE 16 — STOCKHOLDERS’ EQUITY The Corporation also offers to its shareholders a Dividend Reinvestment and Stock Purchase Plan. Participation in this plan by shareholders began in 2001. The plan provides First Keystone shareholders a convenient and economical way to purchase additional shares of common stock by reinvesting dividends. A plan participant can elect full dividend reinvestment or partial dividend reinvestment provided at least 25 shares are enrolled in the plan. In addition, plan participants may make additional voluntary cash purchases of common stock under the plan of not less than $100 per calendar quarter or more than $2,500 in any calendar quarter. Shares transferred under this Dividend Reinvestment and Stock Purchase Plan were 66,775 in 2020 and 52,184 in 2019. Remaining shares authorized in the plan were 458,089 as of December 31, 2020. Shares of First Keystone common stock are purchased for the plan either in the open market by an independent broker on behalf of the plan, directly from First Keystone as original issue shares, or through negotiated transactions. A combination of the previous methods could also occur.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS
FAIR VALUE MEASUREMENTS	NOTE 17 — FAIR VALUE MEASUREMENTS Fair value measurement and disclosure guidance defines fair value as the price that would be received to sell the asset or transfer the liability in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. This guidance provides additional information on determining when the volume and level of activity for the asset or liability has significantly decreased. The guidance also includes information on identifying circumstances when a transaction may not be considered orderly. Fair value measurement and disclosure guidance provides a list of factors that a reporting entity should evaluate to determine whether there has been a significant decrease in the volume and level of activity for the asset or liability in relation to normal market activity for the asset or liability. When the reporting entity concludes there has been a significant decrease in the volume and level of activity for the asset or liability, further analysis of the information from that market is needed and significant adjustments to the related prices may be necessary to estimate fair value in accordance with the fair value measurement and disclosure guidance. This guidance clarifies that when there has been a significant decrease in the volume and level of activity for the asset or liability, some transactions may not be orderly. In those situations, the entity must evaluate the weight of the evidence to determine whether the transaction is orderly. The guidance provides a list of circumstances that may indicate that a transaction is not orderly. A transaction price that is not associated with an orderly transaction is given little, if any, weight when estimating fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity’s own belief about the assumptions market participants would use in pricing the asset or liability based upon the best information available in the circumstances. Fair value measurement and disclosure guidance establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: Level 1 Inputs Level 2 Inputs Level 3 Inputs: A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth as follows. Financial Assets Measured at Fair Value on a Recurring Basis At December 31, 2020 and 2019, securities measured at fair value on a recurring basis and the valuation methods used are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (Dollars in thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ Level 1 Level 2 Level 3 Total Debt Securities Available-for-Sale: ​ ​ ​ ​ U.S. Treasury securities ​ $ — ​ $ — ​ $ — ​ $ — Obligations of U.S. Government Agencies and Sponsored Agencies: ​ ​ ​ ​ ​ ​ Mortgaged-backed ​ — ​ 77,573 ​ — ​ 77,573 Other ​ — ​ 10,430 ​ — ​ 10,430 Other mortgage backed debt securities ​ — ​ 39,844 ​ — ​ 39,844 Obligations of state and political subdivisions ​ — ​ 165,101 ​ — ​ 165,101 Asset backed securities ​ — ​ 44,821 ​ — ​ 44,821 Corporate debt securities ​ — ​ 28,942 ​ — ​ 28,942 Total debt securities available-for-sale ​ — ​ 366,711 ​ — ​ 366,711 Marketable equity securities ​ 1,646 ​ — ​ — ​ 1,646 Total recurring fair value measurements ​ $ 1,646 ​ $ 366,711 ​ $ — ​ $ 368,357 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (Dollars in thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2019 ​ Level 1 Level 2 Level 3 Total Debt Securities Available-for-Sale: ​ ​ ​ ​ U.S. Treasury securities ​ $ — ​ $ 2,855 ​ $ — ​ $ 2,855 Obligations of U.S. Government Agencies and Sponsored Agencies: ​ ​ ​ ​ Mortgaged-backed ​ — ​ 77,283 ​ — ​ 77,283 Other ​ — ​ 10,297 ​ — ​ 10,297 Other mortgage backed debt securities ​ — ​ 11,138 ​ — ​ 11,138 Obligations of state and political subdivisions ​ — ​ 120,376 ​ — ​ 120,376 Asset backed securities ​ — ​ 37,536 ​ — ​ 37,536 Corporate debt securities ​ — ​ 18,443 ​ — ​ 18,443 Total debt securities available-for-sale ​ — ​ 277,928 ​ — ​ 277,928 Marketable equity securities ​ 1,933 ​ — ​ — ​ 1,933 Total recurring fair value measurements ​ $ 1,933 ​ $ 277,928 ​ $ — ​ $ 279,861 ​ The estimated fair values of equity securities classified as Level 1 are derived from quoted market prices in active markets; these assets consist mainly of stocks held in other banks. The estimated fair values of all debt securities classified as Level 2 are obtained from nationally-recognized third-party pricing agencies. The estimated fair values are derived primarily from cash flow models, which include assumptions for interest rates, credit losses, and prepayment speeds. The significant inputs utilized in the cash flow models are based on market data obtained from sources independent of the Corporation (observable inputs), and are therefore classified as Level 2 within the fair value hierarchy. The Corporation does not have any Level 3 inputs for securities. There were no transfers between Level 1 and Level 2 during 2020 and 2019. Financial Assets Measured at Fair Value on a Nonrecurring Basis At December 31, 2020 and 2019, impaired loans measured at fair value on a nonrecurring basis and the valuation methods used are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (Dollars in thousands) Level 1 Level 2 Level 3 Total Assets at December 31, 2020 ​ ​ ​ ​ Impaired loans: ​ ​ ​ ​ Commercial Real Estate ​ $ — ​ $ — ​ $ 6,497 ​ $ 6,497 Residential Real Estate ​ — ​ — ​ 111 ​ 111 Total impaired loans ​ $ — ​ $ — ​ $ 6,608 ​ $ 6,608 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (Dollars in thousands) Level 1 Level 2 Level 3 Total Assets at December 31, 2019 ​ ​ ​ ​ Impaired loans: ​ ​ ​ ​ Commercial Real Estate ​ $ — ​ $ — ​ $ 6,218 ​ $ 6,218 Residential Real Estate ​ — ​ — ​ 221 ​ 221 Total impaired loans ​ $ — ​ $ — ​ $ 6,439 ​ $ 6,439 ​ The Corporation’s impaired loan valuation procedure for any loans greater than $250,000 requires an appraisal to be obtained and reviewed annually at year end unless the Board of Directors waives such requirement for a specific loan, in favor of obtaining a Certificate of Inspection instead. A quarterly collateral evaluation is performed which may include a site visit, property pictures and discussions with realtors and other similar business professionals to ascertain current values. For impaired loans less than $250,000 upon classification and annually at year end, the Corporation completes a Certificate of Inspection, which includes an onsite inspection, and considers value indicators such as insured values, tax assessed values, recent sales comparisons and a review of the previous evaluations. These assets are included as Level 3 fair values, based upon the lowest level that is significant to the fair value measurements. The fair value consists of the impaired loan balances less the valuation allowance and/or charge-offs. There were no transfers between valuation levels in 2020 and 2019. Nonfinancial Assets Measured at Fair Value on a Nonrecurring Basis At December 31, 2020 and 2019, foreclosed assets held for resale measured at fair value on a nonrecurring basis and the valuation methods used are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (Dollars in thousands) Level 1 Level 2 Level 3 Total Assets at December 31, 2020 ​ ​ ​ ​ Foreclosed assets held for resale: ​ ​ ​ ​ Commercial Real Estate ​ $ — ​ $ — ​ $ 28 ​ $ 28 Total foreclosed assets held for resale ​ $ — ​ $ — ​ $ 28 ​ $ 28 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (Dollars in thousands) Level 1 Level 2 Level 3 Total Assets at December 31, 2019 ​ ​ ​ ​ Foreclosed assets held for resale: ​ ​ ​ ​ Commercial Real Estate ​ $ — ​ $ — ​ $ 81 ​ $ 81 Total foreclosed assets held for resale ​ $ — ​ $ — ​ $ 81 ​ $ 81 ​ The Corporation’s foreclosed asset valuation procedure requires an appraisal or a Certificate of Inspection, which considers the sales prices of similar properties in the proximate vicinity, to be completed periodically with the exception of those cases in which the Bank has obtained a sales agreement. These assets are included as Level 3 fair values, based upon the lowest level that is significant to the fair value measurements. There were no transfers between valuation levels in 2020 and 2019. The following table presents additional quantitative information about assets measured at fair value on a nonrecurring basis and for which the Corporation has utilized Level 3 inputs to determine the fair value: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (Dollars in thousands) ​ Quantitative Information about Level 3 Fair Value Measurements ​ ​ Fair Value ​ ​ ​ ​ ​ ​ ​ Weighted December 31, 2020 Estimate Valuation Technique Unobservable Input Range Average Impaired loans - collateral dependent ​ $ 3,679 Appraisal of collateral 1,3 Certificate of Inspection 1,3 Appraisal adjustments 2 Qualitative Adjustments 4 ( 15% ) – ( 73% ) (17%) Impaired loans - other ​ $ 2,929 Discounted cash flow Discount rate ( 7% ) – ( 7% ) (7%) Foreclosed assets held for resale ​ $ 28 Appraisal of collateral 1,3 Certificate of Inspection 1,3 Appraisal adjustments 2 Qualitative Adjustments 4 ( 28% ) –( 28% ) (28%) ​ ​ December 31, 2019 ​ Impaired loans - collateral dependent ​ $ 3,419 Appraisal of collateral 1,3 Certificate of Inspection 1,3 Appraisal adjustments 2 Qualitative Adjustments 4 ( 10% ) – ( 77% ) (17%) Impaired loans - other ​ $ 3,020 Discounted cash flow Discount rate ( 7% ) – ( 8% ) (7%) Foreclosed assets held for resale ​ $ 81 Appraisal of collateral 1,3 Certificate of Inspection 1,3 Appraisal adjustments 2 Qualitative Adjustments 4 ( 35% ) – ( 35% ) (35%) 1.

REVENUE RECOGNITION

REVENUE RECOGNITION	12 Months Ended

REVENUE RECOGNITION
REVENUE RECOGNITION	NOTE 18 — REVENUE RECOGNITION As of January 1, 2018, the Corporation adopted ASU 2014-09 Revenue from Contracts with Customers - Topic 606 The main types of revenue contracts included in non-interest income within the Consolidated Statements of Income which are subject to ASC 606 are as follows: Deposits related fees and service charges Service charges and fees on deposits, which are included as liabilities in the consolidated balance sheets, consist of fees related to monthly fees for various retail and business checking accounts, automated teller machine (“ATM”) fees (charged for withdrawals by our deposit customers from other bank ATMs) and insufficient funds fees (“NSF”) (which are charged when customers overdraw their accounts beyond available funds). All deposit liabilities are considered to have one-day terms and therefore related fees are recognized in income at the time when the services are provided to the customers. The Corporation elected to adopt practical expedient related to incremental costs of obtaining deposit contracts. As such, any costs associated with acquiring the deposits, except for certificate of deposits (“CDs”) with maturities in excess of one year, are recognized as an expense within the non-interest expense in the consolidated statements of income when incurred as the amortization period of the deposit liabilities that otherwise would have been recognized is one year or less. Wealth/Asset/Trust Management Fees Wealth management services are delivered to individuals, corporations and retirement funds located primarily within our geographic markets. The Trust Department of the Corporation conducts the wealth management operations, which provides a broad range of personal and corporate fiduciary services, including the administration of estates. Assets held in a fiduciary capacity by the Trust Department are not assets of the Corporation and, therefore, are not included in our Consolidated Financial Statements. Wealth management fees, which are contractually agreed with each customer, are earned each month and recognized on a cash basis based on average fair value of the trust assets under management. The services provided under such a contract are considered a single performance obligation under ASC 606 because they embody a series of distinct goods or services that are substantially the same and have the same pattern of transfer to the customer. Wealth management fees charged by the Trust Department follow a tiered structure based on the type and size of the assets under management. Wealth management fees are included within non-interest income in the consolidated statements of income. As of December 31, 2020 and 2019, the fair value of trust assets under management was $107,336,000 and $111,160,000, respectively. The costs of acquiring asset management customers are incremental and recognized within the non-interest expense of the consolidated statements of income. Interchange Fees and Surcharges Interchange fees are related to the acceptance and settlement of debit card transactions, both point-of-sale and ATM, to cover operating costs and risks associated with the approval and settlement of the transactions. Interchange fees vary by type of transaction and each merchant sector. Net income recognized from interchange fees is included in non-interest income on the consolidated statements of income. A surcharge is assessed for use of the Corporation’s ATMs by non-customers. All interchange fees and surcharges are recognized as received on a daily basis for the prior business day’s transactions. All expenses related to the settlement of debit card transactions (both point-of-sale and ATM) are recognized on a monthly basis and included in non-interest expense on the consolidated statements of income.

GOODWILL

GOODWILL	12 Months Ended

GOODWILL
GOODWILL	NOTE 19 — GOODWILL Impairment testing is performed using either a qualitative or quantitative approach. The Corporation has selected September 30 as the date it performs the annual goodwill impairment test. Management notes that the emergence of COVID-19 as a global pandemic in 2020 has resulted in significant deterioration in general economic conditions and has caused a deterioration in the environment in which the Corporation operates. This uncertainty has resulted in significant decreases in the market prices for the stock of institutions in the financial services industry, including the Corporation. Based on the totality of the circumstances and the impact of the economic conditions on the stock price, the events more likely than not reduce the fair value of a reporting unit below its carrying amount, including goodwill. As such, an interim quantitative analysis of the fair value of the Corporation as of December 31, 2020 was also performed. The interim quantitative analysis considered both income and market valuation approaches. The income approach used a discounted cash flow analysis based on a five-year forecast of results, including potential cost synergies a market participant would consider. The market approaches took into account the fair value of comparable companies as well as the Corporation’s current stock price adjusted for a control premium. We assigned weightings of 40% to the income approach and 60% to the market approach. The results indicated the Corporation’s fair value exceeded its carrying value and no impairment was recognized. The assumptions used in the impairment test of goodwill are susceptible to change based on changes in economic conditions and other factors, including our stock price. Any change in the assumptions which we utilize to determine the carrying value of goodwill could adversely impact our results of operations. ​

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2020
BASIS OF PRESENTATION AND ACCOUNTING POLICIES
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of First Keystone Corporation and its wholly-owned subsidiary, First Keystone Community Bank (the “Bank”). All significant inter-company balances and transactions have been eliminated in consolidation.
Nature of Operations	Nature of Operations The Corporation, headquartered in Berwick, Pennsylvania, provides a full range of banking, trust and related services through its wholly-owned Bank subsidiary and is subject to competition from other financial institutions in connection with these services. The Bank serves a customer base which includes individuals, businesses, governments, and public and institutional customers primarily located in the Northeast Region of Pennsylvania. The Bank has 18 full service offices, one loan production office, and 20 Automated Teller Machines (“ATM”) located in Columbia, Luzerne, Montour, Monroe, and Northampton counties. The Corporation must also adhere to certain federal and state banking laws and regulations and are subject to periodic examinations made by various state and federal agencies.
Segment Reporting	Segment Reporting The Bank acts as an independent community financial services provider, and offers traditional banking and related financial services to individual, business, government, and public and institutional customers. Through its branch and ATM network, the Bank offers a full array of commercial and retail financial services, including the taking of time, savings and demand deposits; the making of commercial, consumer and mortgage loans; and the providing of other financial services. The Bank also performs personal, corporate, pension and fiduciary services through its Trust Department. Management does not separately allocate expenses, including the cost of funding loan demand, between the commercial, retail, trust and mortgage banking operations of the Corporation. As such, discrete financial information is not available and segment reporting would not be meaningful.
Significant Concentrations of Credit Risk	Significant Concentrations of Credit Risk The majority of the Corporation’s activities involve customers located primarily in Columbia, Luzerne, Montour, Monroe, Northampton, and Lehigh counties in Pennsylvania. The types of securities in which the Corporation invests are presented in Note 3 – Securities. Credit risk as it relates to investment activities is moderated through the monitoring of ratings and geographic concentrations residing in the portfolio and the observance of minimum rating levels in the investment policy. Note 4 – Loans and Allowance for Loan Losses summarizes the types of lending in which the Corporation engages. The inherent risks associated with lending activities are mitigated by adhering to conservative underwriting practices and policies, as well as portfolio diversification and thorough monitoring of the loan portfolio. It is management’s opinion that the investment and loan portfolios were well balanced at December 31, 2020, to the extent necessary to avoid any significant concentrations of credit risk.
Use of Estimates	Use of Estimates The preparation of these consolidated financial statements, in conformity with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of these consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant changes include the determination of other-than-temporary impairment on securities, the determination of the allowance for loan losses, and the assessment of goodwill for possible impairment.
Subsequent Events	Subsequent Events The Corporation has evaluated events and transactions occurring subsequent to the consolidated balance sheet date of December 31, 2020, for items that should potentially be recognized or disclosed in the consolidated financial statements. The evaluation was conducted through the date these consolidated financial statements were issued. On February 23, 2021, the Board of Directors declared a dividend of $0.27 per share for the first quarter of 2021. The dividend is payable on March 31, 2021 to shareholders of record as of March 11, 2021. In addition, on February 23, 2021, the Board of Directors declared a special dividend of $0.01 per share for the first quarter of 2021. The special dividend is also payable on March 31, 2021 to shareholders of record as of March 11, 2021.
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of reporting consolidated cash flows, cash and cash equivalents include cash on hand and due from banks, interest-bearing deposits in other banks, and federal funds sold. The Corporation considers cash classified as interest-bearing deposits with other banks as a cash equivalent since they are represented by cash accounts essentially on a demand basis and mature within one year. Federal funds are also included as a cash equivalent because they are generally purchased and sold for one-day periods.
Time Deposits with Other Banks	Time Deposits with Other Banks Time deposits with other banks consist of fully insured certificates of deposit in other banks with maturity dates between one and five years.
Securities	Securities The Corporation classifies its securities as either “Held-to-Maturity” or “Available-for-Sale” at the time of purchase. Securities are accounted for on a trade date basis. Debt securities are classified as Held-to-Maturity when the Corporation has the ability and positive intent to hold the securities to maturity. Securities classified as Held-to-Maturity are carried at cost adjusted for amortization of premium and accretion of discount to maturity. Debt securities not classified as Held-to-Maturity are included in the Available-for-Sale category and are carried at fair value. The amount of any unrealized gain or loss, net of the effect of deferred income taxes, is reported as accumulated other comprehensive income (AOCI) in the consolidated balance sheets and consolidated statements of changes in stockholders’ equity. Management’s decision to sell Available-for-Sale securities is based on changes in economic conditions controlling the sources and applications of funds, terms, availability of and yield of alternative investments, interest rate risk and the need for liquidity. The cost of debt securities classified as Held-to-Maturity or Available-for-Sale is adjusted for amortization of premiums to the earliest call date and accretion of discounts to expected maturity. Such amortization and accretion, as well as interest and dividends, are included in interest and dividend income on investment securities. Realized gains and losses are included in net investment securities gains and losses. The cost of securities sold, redeemed or matured is based on the specific identification method. Beginning January 1, 2018, upon adoption of Accounting Standard Update 2016-01, equity securities with readily determinable fair values are stated at fair value with realized and unrealized gains and losses reported in income. For periods prior to January 1, 2018, equity securities were classified as Available-for-Sale and stated at fair value with unrealized gains and losses reported as a separate component of AOCI, net of tax. Equity securities without readily determinable fair values are recorded at cost less impairment, if any. Management evaluates securities for other-than-temporary impairment (“OTTI”) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. Securities classified as Available-for-Sale or Held-to-Maturity are generally evaluated for OTTI under FASB ASC 320, Investments - Debt and Equity Securities When OTTI occurs on debt securities, the amount of the OTTI recognized in earnings depends on whether an entity intends to sell the security or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss. If an entity intends to sell or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss, the OTTI shall be recognized in earnings equal to the entire difference between the security’s amortized cost basis and its fair value at the balance sheet date. If an entity does not intend to sell the security and it is not more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis less any current-period loss, the OTTI shall be separated into the amount representing the credit loss and the amount related to all other factors. The amount of the total OTTI related to the credit loss is determined based on the present value of cash flows expected to be collected, and the realized loss is recognized as impairment charges on securities on the consolidated statements of income. The amount of the total OTTI related to the other factors shall be recognized in other comprehensive income (loss), net of applicable taxes. The previous amortized cost basis less the OTTI recognized in earnings becomes the new amortized cost basis of the security. The fair market value of the equity securities tends to fluctuate with the overall equity markets as well as the trends specific to each institution. The equity securities portfolio is reviewed in a similar manner as that of the debt securities with greater emphasis placed on the length of time the market value has been less than the carrying value and the financial sector outlook. The Corporation also reviews dividend payment activities, levels of non-performing assets and loan loss reserves. The starting point for the equity analysis is the length and severity of market value decline. The realized loss is recognized as impairment charges on securities on the consolidated statements of income. The previous cost basis less the OTTI recognized in earnings becomes the new cost basis of the investment.
Restricted Investment in Bank Stocks	Restricted Investment in Bank Stocks The Bank owns restricted stock investments in the Federal Home Loan Bank of Pittsburgh (“FHLB-Pittsburgh”) and Atlantic Community Bankers Bank (“ACBB”). These investments do not have a readily determinable fair value because their ownership is restricted and they can be sold back only to the FHLB-Pittsburgh, ACBB or to another member institution. Therefore, these investments are carried at cost. At December 31, 2020, the Corporation held $2,212,000 in stock of FHLB-Pittsburgh and $35,000 in stock of ACBB. At December 31, 2019, the Corporation held $4,189,000 in stock of FHLB-Pittsburgh and $35,000 in stock of ACBB. Management evaluates the restricted investment in bank stocks for impairment on a quarterly basis. Management’s determination of whether these investments are impaired is based on management’s assessment of the ultimate recoverability of the cost of these investments rather than by recognizing temporary declines in value. The following factors were evaluated to determine the ultimate recoverability of the cost of the Corporation’s restricted investment in bank stocks; (i) the significance of the decline in net assets of the correspondent bank as compared to the capital stock amount for the correspondent bank and the length of time this situation has persisted; (ii) commitments by the correspondent bank to make payments required by law or regulation and the level of such payments in relation to the operating performance of the correspondent bank; (iii) the impact of legislative and regulatory changes on the institutions and, accordingly, on the customer base of the correspondent bank; and (iv) the liquidity position of the correspondent bank. Based on the analysis of these factors, management determined that no impairment charge was necessary related to the restricted investment in bank stocks during 2020 or 2019.
Loans	Loans Net loans are stated at their outstanding recorded investment, net of deferred fees and costs, unearned income and the allowance for loan losses. Interest on loans is recognized as income over the term of each loan, generally, by the accrual method. Loan origination fees and certain direct loan origination costs have been deferred with the net amount amortized using the straight line method or the interest method over the contractual life of the related loans as an interest yield adjustment. The loans receivable portfolio is segmented into commercial, residential and consumer loans. Commercial loans consist of the following classes: Commercial and Industrial and Commercial Real Estate. Commercial and Industrial Lending The Corporation originates commercial and industrial loans primarily to businesses located in its primary market area and surrounding areas. These loans are used for various business purposes, which include short-term loans and lines of credit to finance machinery and equipment, inventory and accounts receivable. Generally, the maximum term for loans extended on machinery and equipment is based on the projected useful life of such machinery and equipment. Most business lines of credit are written on demand and are reviewed annually. Commercial and industrial loans are generally secured with short-term assets; however, in many cases, additional collateral such as real estate is provided as additional security for the loan. Loan-to-value maximum thresholds have been established by the Corporation and are specific to the type of collateral. Collateral values may be determined using invoices, inventory reports, accounts receivable aging reports, business financial statements, collateral appraisals or internal evaluations, etc. Commercial and industrial loans are typically supported by personal guarantees of the borrower. In underwriting commercial and industrial loans, an analysis is performed to evaluate the borrower’s character and capacity to repay the loan, the adequacy of the borrower’s capital and collateral, as well as the conditions affecting the borrower. Evaluation of the borrower’s past, present and future cash flows is also an important aspect of the Corporation’s analysis of the borrower’s ability to repay. Commercial and industrial loans generally present a higher level of risk than other types of loans due primarily to the effect of general economic conditions. Commercial and industrial loans are typically made on the basis of the borrower’s ability to make repayment from cash flows from the borrower’s primary business activities. As a result, the availability of funds for the repayment of commercial and industrial loans is dependent on the success of the business itself, which in turn, is likely to be dependent upon the general economic environment. As an addition to the commercial loans receivable portfolio, the Corporation may purchase the guaranteed portion of loans secured by the U.S. Government. The originating bank retains the unguaranteed portion of the loan. The loans are sponsored by one of the various government agencies including the U.S. Small Business Administration, United States Department of Agriculture (“USDA”), and the Farm Service Agency (“FSA”). Government Guaranteed Loans ("GGLs") carry no credit risk due to an unconditional and irrevocable guarantee (which is supported by the full faith and credit of the U.S. Government) on all principal and the balance of interest accruing through ninety days beyond the date that demand is made to the originating bank for repurchase of the loan. As of December 31, 2020, the Corporation's balance of GGLs amounted to $5,128,000, compared to $6,150,000 at December 31, 2019. Commercial Real Estate Lending The Corporation engages in commercial real estate lending in its primary market area and surrounding areas. The Corporation’s commercial real estate portfolio is secured primarily by commercial retail space, commercial office buildings, residential housing and hotels. Generally, commercial real estate loans have terms that do not exceed twenty years In underwriting these loans, the Corporation performs a thorough analysis of the financial condition of the borrower, the borrower’s credit history, and the reliability and predictability of the cash flow generated by the property securing the loan. The value of the property is determined by either independent appraisers or internal evaluations performed by Bank officers. Commercial real estate loans generally present a higher level of risk than residential real estate secured loans. Repayment of loans secured by commercial real estate is typically dependent upon the successful operation of the related real estate project and/or the effect of the general economic conditions on income producing properties. Residential Real Estate Lending (Including Home Equity) The Corporation’s residential real estate portfolio is comprised of one-to-four family residential mortgage loan originations, home equity term loans and home equity lines of credit. These loans are generated by the Corporation’s marketing efforts, its present customers, walk-in customers and referrals. These loans originate primarily within or with customers from the Corporation’s market area. The Corporation’s one-to-four family residential mortgage originations are secured primarily by properties located in its primary market area and surrounding areas. The Corporation offers fixed-rate mortgage loans with terms up to a maximum of thirty years for both permanent structures and those under construction. Loans with terms of thirty years are normally held for sale and sold without recourse; most of the residential mortgages held in the Corporation’s residential real estate portfolio have maximum terms of twenty years. Generally, the majority of the Corporation’s residential mortgage loans originate with a loan-to-value of eighty percent or less, or those with primary mortgage insurance at ninety-five percent or less. Home equity term loans are secured by the borrower’s primary residence and typically have a maximum loan-to-value of eighty percent and a maximum term of fifteen years. In general, home equity lines of credit are secured by the borrower’s primary residence with a maximum loan-to-value of eighty percent and a maximum term of twenty years. In underwriting one-to-four family residential mortgage loans, the Corporation evaluates the borrower’s ability to make monthly payments, the borrower’s prior loan repayment history and the value of the property securing the loan. The ability and willingness to repay is assessed based upon the borrower’s employment history, current financial conditions and credit background. A majority of the properties securing residential real estate loans made by the Corporation are appraised by independent appraisers. The Corporation generally requires mortgage loan borrowers to obtain an attorney’s title opinion or title insurance and fire and property insurance, including flood insurance, if applicable. Residential mortgage loans, home equity term loans and home equity lines of credit generally present a lower level of risk than consumer loans because they are secured by the borrower’s primary residence. Risk is increased when the Corporation is in a subordinate position, especially to another lender, for the loan collateral. Residential mortgage loans held for sale are carried at the lower of cost or market on an aggregate basis determined by independent pricing from appropriate federal or state agency investors. These loans are sold without recourse. Loans held for sale amounted to $17,300,000 at December 31, 2020 and $2,292,000 at December 31, 2019. Consumer Lending The Corporation offers a variety of secured and unsecured consumer loans, including vehicle loans, stock loans and loans secured by financial institution deposits. These loans originate primarily within or with customers from the Corporation’s market area. Consumer loan terms vary according to the type and value of collateral and creditworthiness of the borrower. In underwriting personal loans, a thorough analysis is performed regarding the borrower’s willingness and financial ability to repay the loan as agreed. The ability and willingness to repay is assessed based upon the borrower’s employment history, current financial condition and credit background. Consumer loans may entail greater credit risk than residential real estate loans, particularly in the case of personal loans which are unsecured or are secured by rapidly depreciable assets, such as automobiles or recreational equipment. In such cases, repossessed collateral for a defaulted personal loan may not provide an adequate source of repayment of the outstanding loan balance as a result of the greater likelihood of damage, loss or depreciation. In addition, personal loan collections are dependent on the borrower’s continuing financial stability and therefore, are more likely to be affected by adverse personal circumstances. Furthermore, the application of various federal and state laws, including bankruptcy and insolvency laws, may limit the amount which can be recovered on such loans. Coronavirus Pandemic Impact on the Loan Portfolio As a result of the economic impact of the COVID-19 coronavirus pandemic, the Coronavirus Aid Relief, and Economic Security (“CARES”) Act was enacted in the United States on March 27, 2020. The Corporation is approved by the SBA to fund loans under the SBA’s Paycheck Protection Program (“PPP”) created as part of the CARES Act. The PPP loans have 1.00% interest rates, lender fees, two or five-year terms (depending on date of origination), and may qualify for forgiveness. These loans funded by the Corporation are subject to the terms and conditions applicable to all loans made pursuant to the PPP, as administered by the SBA under the CARES Act. The Paycheck Protection Program calls for these loans to be fully guaranteed by the SBA. PPP loan origination fees and certain loan origination costs have been deferred with the net amount accreted using the straight line method over the contractual life of the related loans as an interest yield adjustment. If a loan is forgiven pursuant to the terms and conditions applicable to the PPP, the remaining origination fees and costs are recognized at the time of forgiveness. All PPP loans are carried in the Corporation’s Commercial and Industrial loan portfolio. As of December 31, 2020, the Corporation held 441 PPP loans in its Commercial and Industrial portfolio, which carried a balance of $22,976,000. An additional provision of the CARES Act, Section 4013 provides financial institutions the option to suspend requirements to categorize certain loan modifications as troubled debt restructurings, as long as specific criteria are met. To qualify, the loan modifications must be made on a good-faith basis in response to the COVID-19 pandemic, must occur between March 1, 2020 and the earlier of June 30, 2021 or the termination date of the national emergency related to the COVID-19 pandemic as declared by the President of the United States, and the loans must have been paid current (less than 30 days past due prior to any relief) as of December 31, 2019. In compliance with Section 4013 of the CARES Act, the Corporation has granted modification requests to defer principal and/or interest payments or modify interest rates on various loans across all portfolio segments. Of the loan modifications that have been granted in compliance with Section 4013 of the CARES Act, there were 44 loan modifications still actively on deferral carrying an aggregate balance of $16,541,000 as of December 31, 2020. See page 78 for additional information regarding the Section 4013 CARES Act modifications.
Delinquent Loans	Delinquent Loans Generally, a loan is considered to be past-due when scheduled loan payments are in arrears 10 days or more. Delinquent notices are generated automatically when a loan is 10 or 15 days past-due, depending on loan type. Collection efforts continue on past-due loans that have not been brought current, when it is believed that some chance exists for improvement in the status of the loan. Past-due loans are continually evaluated with the determination for charge-off being made when no reasonable chance remains that the status of the loan can be improved. Commercial and Industrial and Commercial Real Estate loans are charged off in whole or in part when they become sufficiently delinquent based upon the terms of the underlying loan contract and when a collateral deficiency exists. Because all or part of the contractual cash flows are not expected to be collected, the loan is considered to be impaired, and the Corporation estimates the impairment based on its analysis of the cash flows or collateral estimated at fair value less cost to sell. Should a Government Guaranteed Loan default, demand is made to the originating bank for repurchase of the loan. If the originating bank does not repurchase the loan, demand for repurchase is then made to the appropriate government agency which has provided the guarantee for the loan. Residential Real Estate and Consumer loans are charged off when they become sufficiently delinquent based upon the terms of the underlying loan contract and when the value of the underlying collateral is not sufficient to support the loan balance and a loss is expected. At that time, the amount of estimated collateral deficiency, if any, is charged off for loans secured by collateral, and all other loans are charged off in full. Loans with collateral are written down to the estimated fair value of the collateral less cost to sell. Existing loans in which the borrower has declared bankruptcy are considered on a case by case basis to determine whether repayment is likely to occur (eg. reaffirmation by the borrower with demonstrated repayment ability). Otherwise, loans are charged off in full or written down to the estimated fair value of collateral less cost to sell. Generally, a loan is classified as non-accrual and the accrual of interest on such a loan is discontinued when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about further collectability of principal or interest, even though the loan may currently be performing. A loan may remain on accrual status if it is well secured (or supported by a strong guarantee) and in the process of collection. When a loan is placed on non-accrual status, unpaid interest credited to income in the current year is reversed and unpaid interest accrued in prior years is charged against interest income. Certain non-accrual loans may continue to perform; that is, payments are still being received. Generally, the payments are applied to principal. These loans remain under constant scrutiny, and if performance continues, interest income may be recorded on a cash basis based on management’s judgment regarding the collectability of principal.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses is established through provisions for loan losses charged against income. Loans deemed to be uncollectible are charged against the allowance for loan losses and subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is maintained at a level estimated by management to be adequate to absorb potential loan losses. Management’s periodic evaluation of the adequacy of the allowance for loan losses 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 (including the timing of future payments), 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 including the amounts and timing of future cash flows expected to be received on impaired loans that may be susceptible to significant change. The allowance consists of specific, general and unallocated components. The specific component relates to loans that are individually classified as impaired. Select loans are not aggregated for collective impairment evaluation, as such; all loans are subject to individual impairment evaluation should the facts and circumstances pertinent to a particular loan suggest that such evaluation is necessary. Factors considered by management in determining impairment include payment status and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. If a loan is impaired, a portion of the allowance may be allocated so that the loan is reported, net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from collateral. Troubled debt restructurings are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using the loan’s effective rate at inception. If a troubled debt restructuring is considered to be a collateral dependent loan, the loan may be reported, net, at the fair value of the collateral. For troubled debt restructurings that subsequently default, the Corporation determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses. The general component covers all other loans not identified as impaired (aside from GGLs, which do not require an allowance) and is based on historical losses and qualitative factors. The historical loss component of the allowance is determined by losses recognized by portfolio segment over a time period that management has determined represents the current credit cycle. Qualitative factors impacting each portfolio segment may include: delinquency trends, loan volume trends, Bank policy changes, management processes and oversight, economic trends (including change in consumer and business disposable incomes, unemployment and under-employment levels, and other conditions), concentrations by industry or product, internal and external loan review processes, collateral value and market conditions, and external factors including regulatory issues and competition. In response to the COVID-19 pandemic and its impact on the current economy, the qualitative factors related to the local/regional economy were increased by two basis points across all loan segments during the first quarter of 2020, and increased by an additional basis point across all loan segments during the second quarter of 2020. The qualitative factor relating to the impact of external factors/conditions for the Commercial Real Estate portfolio segment was increased by an additional basis point during the third quarter of 2020. The qualitative factors relating to the impact of external factors/conditions were increased by two additional basis points across all loan segments during the fourth quarter of 2020. Modifications granted in compliance with Section 4013 of the CARES Act are highest in the Commercial Real Estate portfolio segment, the long-term effects of which are still very unclear, as there is still economic uncertainty related to the COVID-19 pandemic, especially in relation to this segment of the Corporation’s loan portfolio. Government Guaranteed Loans do not require an associated allowance for loan losses due to the underlying irrevocable and unconditional guarantee, which is supported by the full faith and credit of the U.S. Government. Should a GGL default, the loan will be repurchased by the originating bank or the appropriate government agency that has provided the guarantee for the loan. Although PPP loans do not require an associated allowance for loan losses due to the program’s call for a full guarantee by the SBA, the Corporation has taken the conservative approach and has calculated a qualitative allocation for the PPP loans under the general component of the allowance for the Commercial and Industrial portfolio. The unallocated component of the allowance is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. A reserve for unfunded lending commitments is provided for possible credit losses on off-balance sheet credit exposures. The reserve for unfunded lending commitments represents management’s estimate of losses inherent in its unfunded loan commitments and, if necessary, is recorded in other liabilities on the consolidated balance sheets. As of December 31, 2020 and 2019 the amount of the reserve for unfunded lending commitments was $129,000 and $125,000, respectively. The Corporation is subject to periodic examination by its federal and state examiners, and may be required by such regulators to recognize additions to the allowance for loan losses based on their assessment of credit information available to them at the time of their examinations. A loan is considered impaired when, based on current information and events, it is probable that the Corporation will be unable to collect all amounts due according to the contractual terms of the original loan agreement. Under current accounting standards, the allowance for loan losses related to impaired loans is based on discounted cash flows using the loan’s effective interest rate at inception or the fair value of the collateral for certain collateral dependent loans. From time to time, the Corporation may agree to modify/restructure the contractual terms of a borrower's loan. The restructuring of a loan is considered a troubled debt restructuring (“TDR”) if both the following conditions are met: (i) the borrower is experiencing financial difficulties, and (ii) the Corporation has granted a concession. The most common concessions granted include one or more modifications to the terms of the debt, such as (a) a reduction in the interest rate for the remaining life of the debt, (b) an extension of the maturity date at an interest rate lower than the current market rate for new debt with similar risk, (c) a temporary period of interest-only payments, and (d) a reduction in the contractual payment amount for either a short period or remaining term of the loan. A less common concession is the forgiveness of a portion of the principal. The determination of whether a borrower is experiencing financial difficulties takes into account not only the current financial condition of the borrower, but also the potential financial condition of the borrower were a concession not granted. Similarly, the determination of whether a concession has been granted is subjective in nature. For example, simply extending the term of a loan at its original interest rate or even at a higher interest rate could be interpreted as a concession unless the borrower could readily obtain similar credit terms from a different lender. Loans modified in a troubled debt restructuring are considered impaired and may or may not be placed on non-accrual status until the Corporation determines the future collection of principal and interest is reasonably assured, which generally requires that the borrower demonstrates a period of performance according to the restructured terms of six months. Any loan modifications made in response to the COVID-19 pandemic are not considered troubled debt restructurings as long as the criteria set forth in Section 4013 of the CARES Act are met. See page 78 for further discussion of the Section 4013 CARES Act modifications. The Corporation utilizes a risk grading matrix as a tool for managing credit risk in the loan portfolio and assigns an asset quality rating (risk grade) to all Commercial and Industrial, Commercial Real Estate, Residential Real Estate and Consumer borrowings. An asset quality rating is assigned using the guidance provided in the Corporation’s loan policy. Primary responsibility for assigning the asset quality rating rests with the credit department. The asset quality rating is validated periodically by both an internal and external loan review process. The commercial loan grading system focuses on a borrower’s financial strength and performance, experience and depth of management, primary and secondary sources of repayment, the nature of the business and the outlook for the particular industry. Primary emphasis is placed on financial condition and trends. The grade also reflects current economic and industry conditions; as well as other variables such as liquidity, cash flow, revenue/earnings trends, management strengths or weaknesses, quality of financial information, and credit history. The loan grading system for Residential Real Estate and Consumer loans focuses on the borrower’s credit score and credit history, debt-to-income ratio and income sources, collateral position and loan-to-value ratio. Risk grade characteristics are as follows: Risk Grade 1 – MINIMAL RISK through Risk Grade 6 – MANAGEMENT ATTENTION (Pass Grade Categories) Risk is evaluated via examination of several attributes including but not limited to financial trends, strengths and weaknesses, likelihood of repayment when considering both cash flow and collateral, sources of repayment, leverage position, management expertise, and repayment history. At the low-risk end of the rating scale, a risk grade of 1 - Minimal Risk is the grade reserved for loans with exceptional credit fundamentals and virtually no risk of default or loss. Loan grades then progress through escalating ratings of 2 through 6 based upon risk. Risk Grade 2 - Modest Risk are loans with sufficient cash flows; Risk Grade 3 - Average Risk are loans with key balance sheet ratios slightly above the borrower’s peers; Risk Grade 4 - Acceptable Risk are loans with key balance sheet ratios usually near the borrower’s peers, but one or more ratios may be higher; and Risk Grade 5 – Marginally Acceptable are loans with strained cash flow, increasing leverage and/or weakening markets. Risk Grade 6 - Management Attention are loans with weaknesses resulting from declining performance trends and the borrower’s cash flows may be temporarily strained. Loans in this category are performing according to terms, but present some type of potential concern. Risk Grade 7 − SPECIAL MENTION (Non-Pass Category) Assets in this category are currently adequately collateralized but have potential weaknesses that may, if not checked or corrected, weaken the asset or inadequately protect the Corporation’s credit position at some future date. The loans may constitute increased credit risk but not to the point of justifying a classification of substandard. No loss of principal or interest is envisioned, but risk is increasing beyond that at which the loan originally would have been granted. Historically, cash flows are inconsistent; financial trends show some deterioration. Liquidity and leverage ratios are above industry averages. Financial information could be incomplete or inadequate. A Special Mention asset has potential weaknesses that deserve management’s close attention. ​ Risk Grade 8 − SUBSTANDARD (Non-Pass Category) Generally, these assets are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified must have “well-defined” weaknesses that jeopardize the full liquidation of the debt. These loans are characterized by the distinct possibility that the Corporation will sustain some loss if the aggregate amount of substandard assets is not fully covered by the liquidation of the collateral used as security. Substandard loans have a high probability of payment default and require more intensive supervision by Corporation management. Risk Grade 9 − DOUBTFUL (Non-Pass Category) Generally, loans graded doubtful have all the weaknesses inherent in a substandard loan with the added factor that the weaknesses are pronounced to a point whereby the basis of current information, conditions, and values, collection or liquidation in full is deemed to be highly improbable. The possibility of loss is extremely high, but because of certain important and reasonably specific pending factors that may work to strengthen the asset, its classification is deferred until, for example, a proposed merger, acquisition, liquidation procedure, capital injection, perfection of liens on additional collateral and/or refinancing plan is completed. Loans are graded doubtful if they contain weaknesses so serious that collection or liquidation in full is questionable.
Premises and Equipment	Premises and Equipment Premises and equipment are stated at cost less accumulated depreciation computed principally utilizing the straight-line method over the estimated useful lives of the assets. Long-lived assets are reviewed for impairment whenever events or changes in business circumstances indicate that the carrying value may not be recovered. Maintenance and minor repairs are charged to operations as incurred. The cost and accumulated depreciation of the premises and equipment retired or sold are eliminated from the property accounts at the time of retirement or sale, and the resulting gain or loss is reflected in current operations.
Mortgage Servicing Rights	Mortgage Servicing Rights The Corporation originates and sells real estate loans to investors in the secondary mortgage market. After the sale, the Corporation may retain the right to service these loans. The mortgage loans sold and serviced for others are not included in the consolidated balance sheets. The unpaid principal balances of mortgage loans serviced for others were $86,981,000 and $94,998,000 at December 31, 2020 and 2019, respectively. When originated mortgage loans are sold and servicing is retained, a servicing asset is capitalized based on relative fair value at the date of the sale. Servicing assets are amortized as an offset to other fees in proportion to, and over the period of, estimated net servicing income. The servicing asset is included in other assets in the consolidated balance sheets and amounted to $282,000 at December 31, 2020 and $283,000 at December 31, 2019. The amount of servicing income earned was $231,000 and $241,000 at December 31, 2020 and 2019, respectively. Amortization recognized in relation to mortgage servicing rights was $130,000 and $112,000 at December 31, 2020 and 2019, respectively. Both income and amortization are included in service charges and fees on the consolidated statements of income. Gains or losses on sales of mortgage loans are recognized based on the differences between the selling price and the carrying value of the related mortgage loans sold.
Bank Owned Life Insurance	Bank Owned Life Insurance The cash surrender value of bank owned life insurance is carried as an asset, and changes in cash surrender value are recorded as non-interest income. The Corporation entered into agreements to provide post-retirement benefits to two retired employees in the form of life insurance payable to the employee’s beneficiaries upon their death through endorsement split dollar life insurance arrangements. The Corporation’s accrued liabilities for this benefit agreement as of December 31, 2020 and 2019 was $36,000 and $38,000, respectively. The related income for this benefit agreement amounted to $2,000 for the years ended December 31, 2020 and 2019.
Investments in Low-Income Housing Partnerships	Investments in Low-Income Housing Partnerships The Corporation is a limited partner in real estate ventures that own and operate affordable residential low-income housing apartment buildings for elderly and mentally challenged adult residents. The investments are accounted for under the cost method. Under the cost method, the Corporation recognizes tax credits as they are allocated and amortizes the initial cost of the investment over the period that the tax credits are allocated to the Corporation. The amount of tax credits allocated to the Corporation were $405,000 in 2020 and 2019, and the amortization of the investments in the limited partnerships were $362,000 and $353,000 in 2020 and 2019, respectively. During 2015, the Corporation became a limited partner in a real estate venture with an initial investment of $590,000, additional capital contributions of $1,430,000 made in 2016 and 2017 and a final capital contribution of $85,000 made in 2019. The construction was completed and the property was occupied in 2017.
Goodwill	Goodwill Goodwill resulted from the acquisition of the Pocono Community Bank in November 2007 and of certain fixed and operating assets acquired and deposit liabilities assumed of the branch of another financial institution in Danville, Pennsylvania, in January 2004. Such goodwill represents the excess cost of the acquired assets relative to the assets fair value at the dates of acquisition. During the first quarter of 2008, $152,000 of liabilities related to the Pocono acquisition were recorded as a purchase accounting adjustment resulting in an increase in the excess purchase price. The amount was comprised of the finalization of severance agreements and contract terminations related to the acquisition. In accordance with current accounting standards, goodwill is not amortized. Management performs an annual evaluation for impairment. Any impairment of goodwill results in a charge to income. The Corporation periodically assesses whether events or changes in circumstances indicate that the carrying amounts of goodwill and other intangible assets may be impaired. Goodwill is evaluated for impairment at the reporting unit level and an impairment loss is recorded to the extent that the carrying amount of goodwill exceeds its implied fair value. Management notes that the emergence of COVID-19 as a global pandemic during 2020 has resulted in significant deterioration in general economic conditions, and has caused a deterioration in the environment in which the Corporation operates. The full impact to earnings in the banking industry and to the Corporation specifically, remains uncertain. Based on the totality of the circumstances, and the impact of economic conditions, management concluded that it is more likely than not that the fair value of the reporting unit is less than its carrying amount. Management engaged an independent third party to perform the quantitative analysis of comparing the fair value of the Corporation to its carrying value, including goodwill. The results of the quantitative goodwill impairment analysis concluded that there was impairment as of December 31, 2020. In addition, the Corporation did not identify any impairment in 2019. No assurance can be given that future impairment tests will not result in a charge to earnings.
Foreclosed Assets Held for Resale	Foreclosed Assets Held for Resale Real estate properties acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value less cost to sell on the date of foreclosure, establishing a new cost basis. After foreclosure, valuations are periodically performed and if fair value less cost to sell declines subsequent to foreclosure, a valuation allowance is recorded through expense. Revenues derived from and costs to maintain the assets and subsequent gains and losses on sales are included in non-interest expense on the consolidated statements of income.
Income Taxes	Income Taxes The Corporation accounts for income taxes in accordance with income tax accounting guidance FASB ASC Topic 740, Income Taxes. Current income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Corporation determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are reduced by a valuation allowance if, based on the weight of the evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. The Corporation accounts for uncertain tax positions if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more-likely-than-not means a likelihood of more than 50%; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management’s judgment. The Corporation recognizes interest and penalties on income taxes, if any, as a component of income tax expense.
Earnings Per Share	Earnings Per Share Basic earnings per share (“EPS”) is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the Corporation. At December 31, 2020 and 2019, there were no potential common shares outstanding. The following table sets forth the computation of basic and diluted earnings per share. ​ ​ ​ ​ ​ ​ ​ ​ (In thousands, except earnings per share) ​ ​ ​ ​ Year Ended December 31, ​ 2020 2019 Net income ​ $ 11,837 ​ $ 10,227 Weighted-average common shares outstanding ​ 5,841 ​ 5,784 Basic and diluted earnings per share ​ $ 2.03 ​ $ 1.77 ​
Treasury Stock	Treasury Stock The purchase of the Corporation’s common stock is recorded at cost. At the date of subsequent reissue, the treasury stock account is reduced by the cost of such stock on a first-in-first-out basis.
Trust Assets And Revenues	Trust Assets and Revenues Property held by the Corporation in a fiduciary or agency capacity for its customers is not included in the accompanying consolidated financial statements since such items are not assets of the Corporation. Assets held in trust were $107,336,000 and $111,160,000 at December 31, 2020 and 2019, respectively. Trust Department income is generally recognized on a cash basis and is not materially different than if it were reported on an accrual basis (see Table 4 – Non-Interest Income for details).
Comprehensive Income (Loss)	Comprehensive Income (Loss) The Corporation is required to present accumulated other comprehensive income (loss) in a full set of general-purpose financial statements for all periods presented. Accumulated other comprehensive income (loss) is comprised of net unrealized holding gains (losses) on the debt securities available-for-sale portfolio. The Corporation has elected to report these effects on the consolidated statements of comprehensive income.
Advertising Costs	Advertising Costs It is the Corporation’s policy to expense advertising costs in the period in which they are incurred.
Recent Accounting Standards Updates (?ASU?) ? Adopted:	Recent Accounting Standards Updates (“ASU”) – Adopted: Except as disclosed below, there were no new accounting pronouncements affecting the Corporation during the year ended December 31, 2020 that were not already adopted by the Corporation in previous periods. Recently adopted ASUs: In January 2017, the Financial Accounting Standards Board (“FASB”) issued ASU 2017-04, Intangibles –Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment In August 2018, the FASB issued ASU 2018-13 , Fair Value Measurement (Topic 820) – Disclosure Framework – Changes to Disclosure Requirements for Fair Value Measurement . The amendments in this update removed required disclosures regarding: 1. The amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, 2. The policy for timing of transfers between levels, 3. The valuation processes for Level 3 fair value measurements, and 4. The update modified the disclosure requirements on fair value measurements in Topic 820: a) The changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and b) The range and weighted average significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. The amendments in this update were effective for all entities for fiscal years, and interim periods within those fiscal years beginning after December 15, 2019. The adoption of this update on January 1, 2020 did not have a material impact on the Corporation's consolidated financial statements and related disclosures. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) , which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by the discontinuation of the London Interbank Offered Rate ("LIBOR"), or by another reference rate that is expected to be discontinued. The amendments are effective for all entities as of March 12, 2020 through December 31, 2022. The Corporation has evaluated the impact of the provisions of ASU 2020-04 on our financial condition, results of operations and cash flows, and determined that there is no material impact on the consolidated financial statements and related disclosures. Pending ASUs: In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326):
Transfer of Financial Assets	Transfer of Financial Assets Transfers of financial assets are accounted for as sales when control over assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Corporation, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Corporation does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Off-Balance Sheet Financial Instruments	Off-Balance Sheet Financial Instruments In the ordinary course of business, the Corporation has entered into off-balance sheet financial instruments consisting of commitments to extend credit and letters of credit. Such financial instruments are recorded in the consolidated balance sheets when they are funded.
Reclassifications	Reclassifications Certain amounts previously reported have been reclassified, when necessary, to conform with presentations used in the 2020 consolidated financial statements. Such reclassifications have no effect on the Corporation’s net income.
