Accounting Policies [Abstract]
Summary of significant accounting policies	1. Summary of significant accounting policies: Nature of Operations: Riverview Financial Corporation, (the “Company” or “Riverview”), a bank holding company incorporated under the laws of Pennsylvania, provides a full range of financial services through its wholly-owned subsidiary, Riverview Bank (the “Bank”). Riverview Bank, with 27 full service offices and three limited purpose offices, is a full-service commercial bank offering a wide range of traditional banking services and financial advisory, insurance and investment services to individuals, municipalities and small to medium sized businesses in the Pennsylvania market areas of Berks, Blair, Bucks, Centre, Clearfield, Cumberland, Dauphin, Huntingdon, Lebanon, Lehigh, Lycoming, Perry, Schuylkill and Somerset Counties. The Bank is state-chartered under the jurisdiction of the Pennsylvania Department of Banking and Securities and the Federal Deposit Insurance Corporation. The Bank’s primary product is loans to small- and medium-sized one-to-four The wealth management and trust divisions did not meet the quantitative thresholds for required segment disclosure in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Bank’s 30 community banking offices, all similar with respect to economic characteristics, share a majority of the following aggregation criteria: (i) products and services; (ii) operating processes; (iii) customer bases; (iv) delivery systems; and (v) regulatory oversight. Accordingly, they were aggregated into a single operating segment. The Company faces competition primarily from commercial banks, thrift institutions and credit unions within the Central, Northern, Southwestern and Southeastern Pennsylvania markets, many of which are substantially larger in terms of assets and capital. In addition, mutual funds and security brokers compete for various types of deposits, and consumer, mortgage, leasing and insurance companies compete for various types of loans and leases. Principal methods of competing for banking and permitted nonbanking services include price, nature of product, quality of service and convenience of location. The Company and the Bank are subject to regulations of certain federal and state regulatory agencies and undergo periodic examinations. Basis of presentation: The consolidated financial statements of the Company have been prepared in conformity with GAAP, Regulation S-X The operating results and financial position of the Company for the year ended as of December 31, 2020, are not necessarily indicative of the results of operations and financial position that may be expected in the future. This is especially true given the outbreak of the Coronavirus (“COVID-19”) pandemic which has adversely affected the Company’s business results of operations and financial condition in 2020. The impact of the pandemic on Riverview’s financial results is evolving and uncertain. The Company expects its net interest income and non-interest COVID-19 COVID-19 Estimates: To prepare financial statements in conformity with accounting principles generally accepted in the United States of America management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ. Investment securities: Investment securities are classified and accounted for as either held-to-maturity, available-for-sale, held-to Held-to-maturity available-for-sale Available-for-sale available-for-sale Management evaluates each investment security at least quarterly, to determine if a decline in fair value below its amortized cost is an other-than-temporary impairment (“OTTI”), and more frequently when economic or market concerns warrant an evaluation. Factors considered in determining whether an other-than-temporary impairment was incurred include: (i) the length of time and the extent to which the fair value has been less than amortized cost; (ii) the financial condition and near-term prospects of the issuer; (iii) whether a decline in fair value is attributable to adverse conditions specifically related to the security or specific conditions in an industry or geographic area; (iv) the credit-worthiness of the issuer of the security; (v) whether dividend or interest payments have been reduced or have not been made; (vi) an adverse change in the remaining expected cash flows from the security such that the Company will not recover the amortized cost of the security; (vii) whether management intends to sell the security; and (viii) if it is more likely than not that management will be required to sell the security before recovery. If a decline is judged to be other-than-temporary, the individual security is written-down to fair value with the credit related component of the write-down included in earnings and the non-credit Loans held for sale: Loans held for sale consist of one-to-four Loans, net: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at their outstanding unpaid principal balances, net of deferred fees or costs. Interest income is accrued on the principal amount outstanding. Loan origination fees, net of certain direct origination costs, are deferred and recognized over the contractual life of the related loan as an adjustment to yield using the effective interest method. Premiums and discounts on purchased loans are amortized as adjustments to interest income using the effective interest method. Delinquency fees are recognized in income when chargeable, assuming collectability is reasonably assured. Transfers of financial assets, which include loan participation sales, are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when: (i) the assets have been isolated from the Company; (ii) 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 (iii) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. The loan portfolio is segmented into business, construction and retail loans. Business loans consist of commercial and commercial real estate loans. Construction loans consist of both commercial and residential loans. Retail loans consist of residential real estate and other consumer loans.​​​​​​​ The Company makes commercial loans for real estate development and other business purposes required by the customer base. The Company’s credit policies determine advance rates against the different forms of collateral that can be pledged against commercial loans. Typically, the majority of loans will be limited to a percentage of their underlying collateral values such as real estate values, equipment, eligible accounts receivable and inventory. Individual loan advance rates may be higher or lower depending upon the financial strength of the borrower and/or term of the loan. The assets financed through commercial loans are used within the business for its ongoing operation. Repayment of these kinds of loans generally comes from the cash flow of the business or the ongoing conversion of assets. Commercial real estate loans include long-term loans financing commercial properties. Repayment of these loans is dependent upon either the ongoing cash flow of the borrowing entity or the resale of or lease of the subject property. Commercial real estate loans typically require a loan to value of not greater than 80% and vary in terms. Commercial and commercial real estate loans generally have higher credit risk compared to residential mortgage loans and consumer loans, as they typically involve larger loan balances concentrated with single borrowers or groups of borrowers. In addition, the payment expectations on loans secured by income-producing properties typically depend on the successful operations of the related business and thus may be subject to a greater extent to adverse conditions in the real estate market and in the general economy. Loans secured by commercial real estate generally have larger balances and involve a greater degree of risk than one-to-four Residential mortgages, including home equity loans, are secured by the borrower’s residential real estate in either a first or second lien position. Residential mortgages have varying loan rates depending on the financial condition of the borrower and the loan to value ratio. Residential mortgages may have amortizations up to 30 years. Consumer loans include installment loans, car loans, and overdraft lines of credit. The majority of these loans are secured. Consumer loans may entail greater risk than do residential mortgage loans, particularly in the case of consumer loans that are unsecured or secured by assets that depreciate rapidly, such as motor vehicles. In the latter case, repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment for the outstanding loan and a small remaining deficiency often does not warrant further substantial collection efforts against the borrower. Consumer loan collections depend on the borrower’s continuing financial stability, and therefore are likely to be adversely affected by various factors, including job loss, divorce, illness or personal bankruptcy. Furthermore, the application of various federal and state laws, including federal and state insolvency laws, may limit the amount that can be recovered on such loans. Leases: The Company’s primary leasing activities relate to certain real estate leases entered into in support of the Company’s branch and back office operations. The Company’s branch locations operating under lease agreements have all been designated as operating leases. In addition, the Company leases certain equipment under operating leases. The Company does not have leases designated as finance leases. The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease pre-payments non-lease non-lease Off-balance In the ordinary course of business, the Company enters into off-balance off-balance Nonperforming assets: Nonperforming assets consist of nonperforming loans and other real estate owned. Nonperforming loans include nonaccrual loans, troubled debt restructured loans and accruing loans past due 90 days or more. Past due status is based on contractual terms of the loan. Generally, a loan is classified as nonaccrual when it is determined that the collection of all or a portion of interest or principal is doubtful or when a default of interest or principal has existed for 90 days or more, unless the loan is well secured and in the process of collection. When a loan is placed on nonaccrual, interest accruals are discontinued, and uncollected accrued interest is reversed against income in the current period. Interest collections after a loan has been placed on nonaccrual status are credited to the principal balance. Interest earned that would have been recognized is credited to income over the remaining life of the loan using the effective yield method if the nonaccrual loan is returned to performing status. A nonaccrual loan is returned to performing status when the loan is current as to principal and interest and has performed according to the contractual terms for a minimum of six months. Troubled debt restructured loans are loans with original terms, interest rate, or both, that have been modified as a result of a deterioration in the borrower’s financial condition and a concession has been granted that the Company would not otherwise consider. Unless on nonaccrual, interest income on these loans is recognized when earned, using the interest method. The Company offers a variety of modifications to borrowers that would be considered concessions. The modification categories offered can generally fall within the following categories: • Rate Modification — A modification in which the interest rate is changed to a below market rate. • Term Modification — A modification in which the maturity date, timing of payments or frequency of payments is changed. • Interest Only Modification — A modification in which the loan is converted to interest only payments for a period of time. • Payment Modification — A modification in which the dollar amount of the payment is changed, other than an interest only modification described above. • Combination Modification — Any other type of modification, including the use of multiple categories above. In March 2020, a joint policy statement was issued by federal and state regulatory agencies to clarify that short-term loan modifications made in good-faith to provide temporary payment relief to borrowers directly impacted by COVID-19 The Company segments loans into risk categories based on relevant information about the ability of borrowers to service their debt such as current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. Loans are individually analyzed for credit risk by classifying them within the Company’s internal risk rating system. The Company’s risk rating classifications are defined as follows: • Pass — A loan to borrowers with acceptable credit quality and risk that is not adversely classified as Substandard, Doubtful, Loss or designated as Special Mention. • Special Mention — A loan that has potential weaknesses that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or in the institution’s credit position at some future date. Special Mention loans are not adversely classified since they do not expose the Company to sufficient risk to warrant adverse classification. • Substandard — A loan that is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. • Doubtful — A loan classified as Doubtful has all the weaknesses inherent in one classified Substandard with the added characteristic that the weaknesses make the collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. • Loss — A loan classified as Loss is considered uncollectible and of such little value that its continuance as a bankable loan is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be effected in the future. Other real estate owned is comprised of properties acquired through foreclosure proceedings or in-substance in-substance Allowance for loan losses: The allowance for loan losses represents management’s estimate of losses inherent in the loan portfolio as of the balance sheet date. The allowance for loan losses account is maintained through a provision for loan losses charged to earnings. Loans, or portions of loans, determined to be confirmed losses are charged against the allowance account and subsequent recoveries, if any, are credited to the account. A loss is considered confirmed when information available at the financial statement date indicates the loan, or a portion thereof, is uncollectible. Nonaccrual, troubled debt restructured, and loans deemed impaired at the time of acquisition are reviewed monthly to determine if carrying value reductions are warranted or if these classifications should be changed. Consumer loans are considered losses and charged-off Management evaluates the adequacy of the allowance for loan losses account quarterly. This assessment is based on past charge-off The allowance for loan losses is maintained at a level believed to be adequate to absorb probable credit losses related to specifically identified loans, as well as probable incurred losses inherent in the remainder of the loan portfolio as of the balance sheet date. The allowance for loan losses consists of an allocated element and an unallocated element. The allocated element consists of a specific allowance for impaired loans individually evaluated under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 310, “Receivables,” and a formula portion for loss contingencies on those loans collectively evaluated under FASB ASC 450, “Contingencies.” A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. All amounts due according to the contractual terms means that both the contractual interest and principal payments of a loan will be collected as scheduled in the loan agreement. Factors considered by management in determining impairment include payment status, ability to pay 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 The formula portion of the allowance for loan losses relates to large pools of smaller-balance homogeneous loans and those identified loans considered not individually impaired having similar characteristics as these loan pools. Loss contingencies for each of the major loan pools are determined by applying a total loss factor to the current balance outstanding for each individual pool. The total loss factor is comprised of a historical loss factor using a loss migration method plus qualitative factors, which adjust the historical loss factor for changes in trends, conditions and other relevant factors that may affect repayment of the loans in these pools as of the evaluation date. Loss migration involves determining the percentage of each pool that is expected to ultimately result in loss based on historical loss experience. Historical loss factors are based on the ratio of net loans charged-off charge-off charge-off The unallocated element, if any, is used to cover inherent losses that exist as of the evaluation date, but which have not been identified as part of the allocated allowance using the above impairment evaluation methodology due to limitations in the process. One such limitation is the imprecision of accurately estimating the impact current economic conditions will have on historical loss rates. Variations in the magnitude of impact may cause estimated credit losses associated with the current portfolio to differ from historical loss experience, resulting in an allowance that is higher or lower than the anticipated level. Management establishes the unallocated element of the allowance by considering environmental risks similar to the ones used for determining the qualitative factors. Management continually monitors trends in historical and qualitative factors, including trends in the volume, composition and credit quality of the portfolio. The reasonableness of the unallocated element is evaluated through monitoring trends in its level to determine if changes from period to period are directionally consistent with changes in the loan portfolio. Management believes the level of the allowance for loan losses was adequate to absorb probable credit losses as of December 31, 2020. Premises and equipment, net: Land is stated at cost. Premises, equipment and leasehold improvements are stated at cost less accumulated depreciation and amortization. The cost of routine maintenance and repairs is expensed as incurred. The cost of major replacements, renewals and betterments is capitalized. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation and amortization are eliminated, and any resulting gain or loss is reflected in noninterest income. computed principally using the straight-line method based on the following estimated useful lives of the related assets, or in the case of leasehold improvements, to the expected terms of the leases, if shorter: Premises and leasehold improvements 7 Leasehold improvements 10 Furniture, fixtures and 3 Business combinations, goodwill and other intangible assets, net: The Company accounts for its acquisitions using the purchase accounting method. Purchase accounting requires the total purchase price to be allocated to the estimated fair values of assets acquired and liabilities assumed, including certain intangible assets that must be recognized. Typically, this allocation results in the purchase price exceeding the fair value of net assets acquired, which is recorded as goodwill. Core deposit intangibles are a measure of the value of checking, money market and savings deposits acquired in business combinations accounted for under the purchase method. Core deposit intangibles and other identified intangibles with finite useful lives are amortized using the sum of the year’s digits over their estimated useful lives of up to ten years. Loans that the Company acquires in connection with acquisitions are recorded at fair value with no carryover of the related allowance for credit losses. Fair value of the loans involves estimating the amount and timing of principal and interest cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. The excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is recognized into interest income over the remaining life of the loan. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the non-accretable non-accretable non-accretable non-accretable The Company accounts for performing loans acquired in business combinations using the contractual cash flows method of recognizing discount accretion based on the acquired loans’ contractual cash flows. Purchased performing loans are recorded at fair value, including a credit discount. The fair value discount is accreted as an adjustment to yield over the estimated lives of the loans. There is no allowance for loan losses established at the acquisition date for purchased performing loans. A provision for loan losses is recorded for any further deterioration in these loans subsequent to the acquisition. Customer list intangibles are also included in intangible assets as a result of the purchase of the wealth management companies. These intangibles are amortized as an expense over Goodwill and other intangible assets are tested for impairment annually during the fourth quarter of each year or when circumstances arise which are considered to be a triggering event indicating impairment may have occurred. In making this assessment that impairment has occurred, management considers a number of factors including, but not limited to, operating results, business plans, economic projections, anticipated future cash flows, and current market data. There are inherent uncertainties related to these factors and management’s judgment in applying them to the analysis of impairment. Changes in economic and operating conditions, as well as other factors, could result in impairment in future periods. Any impairment losses arising from such testing would be reported in the Consolidated Statements of Income and Comprehensive Income as a separate line item within operations. The Company recognized an impairment charge equal to the entire amount of its recorded goodwill on the balance sheet at June 30, 2020 totaling $24,754. For additional disclosure related to the goodwill impairment charge refer to the note entitled “Goodwill” in the Notes to Consolidated Financial Statements. There were no impairment losses recognized as a result of periodic impairment testing for the year ended December 31, 2019. Restricted equity securities: As a member of the Federal Home Loan Bank of Pittsburgh (“FHLB-Pgh”) FHLB-Pgh Bank owned life insurance: The Company invests in bank owned life insurance (“BOLI”) as a source of funding for employee benefit expenses. BOLI involves the purchasing of life insurance by the Bank on certain of its directors and employees. The Bank is the owner and beneficiary of the policies. This life insurance investment is carried at the cash surrender value of the underlying policies and is included in other assets. Income from increases in cash surrender value of the policies is included in noninterest income. Pension and post-retirement benefit plans: The Company sponsors various pension plans covering substantially all employees. The Company also provides post-retirement benefit plans other than pensions, consisting principally of life insurance benefits, to eligible retirees. The liabilities and annual income or expense of the Company’s pension and other post-retirement benefit plans are determined using methodologies that involve several actuarial assumptions, the most significant of which are the discount rate and the long-term rate of asset return, based on the market-related value of assets. The fair values of plan assets are determined based on prevailing market prices or estimated fair value for investments with no available quoted prices. Derivative Instruments and Hedging Activities: The Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. As of and for the year ended December 31, 2020, the Company’s derivative instruments and hedging activities consisted entirely of interest rate swap hedges on its holdings of trust preferred securities. These interest rate swaps are designated as cash flow hedges and involve the receipt of variable rate amounts from a counterparty in exchange for the Company making fixed payments. A cash flow hedge is a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Cash flows on hedges are classified in the consolidated statements of cash flows the same as the cash flows of the items being hedged. The Company formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions at the inception of the hedging relationship. This documentation includes linking fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Company discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as other income. When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in other comprehensive income are amortized into earnings over the same periods which the hedged transaction will affect earnings. The Company is exposed to losses if a counterparty fails to make its payments under a contract in which the Company is in the net receiving position. The Company anticipates that the counterparties will be able to fully satisfy their obligations under the agreements. The contract to which the Company is a party settles monthly. Statements of Cash Flows The Consolidated Statements of Cash Flows are presented using the indirect method. For purposes of cash flow, cash and cash equivalents include cash on hand, cash items in the process of collection, noninterest-bearing and interest-bearing deposits in other banks and federal funds sold. Fair value of financial instruments: The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosure under GAAP. Fair value estimates are calculated without attempting to estimate the value of anticipated future business and the value of certain assets and liabilities that are not considered financial. Accordingly, such assets and liabilities are excluded from disclosure requirements. In accordance with FASB ASC 820, “Fair Value Measurements and Disclosures”, fair value is the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets. In many cases, these values cannot be realized in immediate settlement of the instrument. Current fair value guidance provides a consistent definition of fair value, which focuses on exit price in an orderly transaction that is not a forced liquidation or distressed sale between participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions. In accordance with GAAP, the Company groups its assets and liabilities, generally measured at fair value, into three levels based on market information or other fair value estimates in which the assets and liabilities are traded or valued, and the reliability of the assumptions used to determine fair value. These levels include: • Level 1: Unadjusted quoted prices of identical assets or liabilities in active markets that the entity has the ability to access as of

Cash and due from banks	2. Cash and due from banks: Historically the Bank was required to maintain average reserve balances in cash or on deposit with the Federal Reserve Bank. On March 26, 2020, the Federal Reserve Bank reduced the reserve percentages to 0%. There was no required reserve at December 31, 2020 and 2019. In addition, the Bank’s other correspondents may require average compensating balances as part of their agreements to provide services. The Bank maintains balances with correspondent banks that may exceed federal insured limits, which management considers to be a normal business risk.

Loans, net and allowance for loan losses	4. Loans, net and allowance for loan losses: The major classifications of loans outstanding, net of deferred loan origination fees and costs at December 31, 2020 and 2019 are summarized as follows. Net deferred December 31 2020 2019 Commercial $ 359,080 $ 118,658 Real estate: Construction 73,402 61,831 Commercial 502,495 455,901 Residential 197,596 207,354 Consumer 6,666 8,365 Total $ 1,139,239 $ 852,109 The Company participated in the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”), Paycheck Protection Program (“PPP”), a multi-billion dollar specialized low-interest of PPP loans, net of unearned fees of $5,075, included in commercial loans at December 31, 2020. The Company is utilizing the Federal Reserve’s Paycheck Protection Program Liquidity Facility (“PPPLF”) to meet the funding needs of its borrowers of PPP loans. Additionally, the Company is working with borrowers impacted by COVID-19 and providing modifications to include interest only deferral or principal and interest deferral up to 180 days. The majority of deferrals approved by the Company were 90 days or less. The modifications are excluded from troubled debt restructuring classification under the CARES Act. The Company modified 325 commercial and 176 consumer loans with outstanding balances of $256,422 at time of deferral, during the year ended December 31, 2020. As of December 31, 2020, 19 modified loans remained on deferral with an outstanding balance of $21,854. Loans outstanding to directors, executive officers, principal stockholders or to their affiliates totaled $17,800 and $9,518 at December 31, 2020 and 2019, respectively. Advances and repayments during 2020, totaled $15,880 and $7,598, respectively. There were no related party loans that were classified as nonaccrual, past due, or restructured or considered a potential credit risk at December 31, 2020 and 2019. At December 31, 2020, the majority of the Company’s loans were at least partially secured by real estate located in Central and Southwestern Pennsylvania. Therefore, a primary concentration of credit risk is directly related to the real estate market in these areas. Changes in the general economy, local economy or in the real estate market could affect the ultimate collectability of this portion of the loan portfolio. Management does not believe there are any other significant concentrations of credit risk that could affect the loan portfolio. The changes in the allowance for loan losses account by major classification of loan for the years ended December 31, 2020 and 2019 are summarized as follows: Real Estate December 31, 2020 Commercial Construction Commercial Residential Consumer Unallocated Total Allowance for loan losses: Beginning Balance January 1, 2020 $ 1,953 $ 473 $ 3,115 $ 1,820 $ 155 $ $ 7,516 Charge-offs (909 ) (595 ) (2 ) (333 ) (1,839 ) Recoveries 11 61 1 168 241 Provisions 650 644 3,913 608 152 315 6,282 Ending balance $ 1,705 $ 1,117 $ 6,494 $ 2,427 $ 142 $ 315 $ 12,200 Real Estate December 31, 2019 Commercial Construction Commercial Residential Consumer Unallocated Total Allowance for loan losses: Beginning Balance January 1, 2019 $ 1,162 $ 404 $ 3,298 $ 1,286 $ 50 $ 148 $ 6,348 Charge-offs (1,128 ) (254 ) (26 ) (476 ) (1,884 ) Recoveries 484 6 7 149 646 Provisions 1,435 69 65 553 432 (148 ) 2,406 Ending balance $ 1,953 $ 473 $ 3,115 $ 1,820 $ 155 $ $ 7,516 The allocation of the allowance for loan losses and the related loans by major classifications of loans at December 31, 2020 and December 31, 2019 is summarized as follows: Real Estate December 31, 2020 Commercial Construction Commercial Residential Consumer Unallocated Total Allowance for loan losses: Ending balance $ 1,705 $ 1,117 $ 6,494 $ 2,427 $ 142 $ 315 $ 12,200 Ending balance: individually evaluated for impairment Ending balance: collectively evaluated for impairment 1,705 1,117 6,494 2,427 142 315 12,200 Ending balance: purchased credit impaired loans $ $ $ $ $ $ $ Loans receivable: Ending balance $ 359,080 $ 73,402 $ 502,495 $ 197,596 $ 6,666 $ $ 1,139,239 Ending balance: individually evaluated for impairment 1,565 6,444 2,494 10,503 Ending balance: collectively evaluated for impairment 357,515 73,402 495,674 194,939 6,666 1,128,196 Ending balance: purchased credit impaired loans $ $ $ 377 $ 163 $ $ $ 540 Real Estate December 31, 2020 Commercial Construction Commercial Residential Consumer Unallocated Total Allowance for loan losses: Ending balance $ 1,953 $ 473 $ 3,115 $ 1,820 $ 155 $ $ 7,516 Ending balance: individually evaluated for impairment 712 218 930 Ending balance: collectively evaluated for impairment 1,241 473 2,897 1,820 155 6,586 Ending balance: purchased credit impaired loans $ $ $ $ $ $ $ Loans receivable: Ending balance $ 118,658 $ 61,831 $ 455,901 $ 207,354 $ 8,365 $ $ 852,109 Ending balance: individually evaluated for impairment 2,260 1,224 2,085 5,569 Ending balance: collectively evaluated for impairment 116,390 61,831 453,156 205,026 8,365 844,768 Ending balance: purchased credit impaired loans $ 8 $ $ 1,521 $ 243 $ $ $ 1,772 The following tables present the major classification of loans summarized by the aggregate pass rating and the classified ratings of special mention, substandard and doubtful within the Company’s internal risk rating system at December 31, 2020 and 2019: December 31, 2020: Pass Special Mention Substandard Doubtful Total Commercial $ 353,758 $ 3,147 $ 2,175 $ $ 359,080 Real estate: Construction 63,838 1,817 7,747 73,402 Commercial 451,190 29,180 22,125 502,495 Residential 191,775 2,670 3,151 197,596 Consumer 6,666 6,666 Total $ 1,067,227 $ 36,814 $ 35,198 $ $ 1,139,239 December 31, 2019: Pass Special Mention Substandard Doubtful Total Commercial $ 109,190 $ 5,992 $ 3,476 $ $ 118,658 Real estate: Construction 61,678 153 61,831 Commercial 430,771 9,271 15,859 455,901 Residential 203,381 1,437 2,536 207,354 Consumer 8,365 8,365 Total $ 813,385 $ 16,853 $ 21,871 $ $ 852,109 The following tables present the classes of the loan portfolio summarized by the aging categories of performing loans and nonaccrual loans as of December 31, 2020 and 2019.

Off-balance sheet financial instruments	5. Off-balance The Company is a party to financial instruments with off-balance The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit, unused portions of lines of credit and standby letters of credit is represented by the contractual amounts of those instruments. The Company follows the same credit policies in making commitments and conditional obligations as it does for on-balance off-balance The contractual amounts of off-balance December 31 2020 2019 Commitments to extend credit $ 70,474 $ 105,403 Unused portions of lines of credit 75,517 66,114 Standby letters of credit 6,577 4,726 $ 152,568 $ 176,243 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. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The Company evaluates each customer’s credit worthiness on a case-by-case Unused portions of lines of credit, including home equity and overdraft protection agreements, are commitments for possible future extensions of credit to existing customers. Unused portions of home equity lines are collateralized and generally have fixed expiration dates. Overdraft protection agreements are uncollateralized and usually do not carry specific maturity dates. Unused portions of lines of credit ultimately may not be drawn upon to the total extent to which the Company is committed. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Generally, all standby letters of credit expire within twelve months. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending other loan commitments. The Company requires collateral supporting these standby letters of credit as deemed necessary. The carrying value of the liability for the Company’s obligations under guarantees for standby letters of credit was not material at December 31, 2020 and 2019.

Goodwill	8. Goodwill: The following table summarizes activity related to the carrying value of goodwill for the year ended December 31, 2020: Balance, January 1, 2020 $ 24,754 Less: Goodwill impairment 24,754 Balance, December 31, 2020 $ Accounting guidance requires the Company to test its goodwill impairment at least annually, or more frequently, if an event occurs or circumstances change which are considered to be a triggering event that would more likely than not reduce the fair value of its goodwill below the carrying value of the reporting unit, Riverview Bank. The Company noted that at the beginning of the second quarter of 2020, as a result of the onset of the COVID-19 pandemic, the market price of its common shares decreased significantly below the carrying value of its equity per share and that it did not recover during the second quarter of 2020. This decrease prompted the Company to assess its goodwill utilizing a quantitative test to determine whether it was more-likely-than-not the fair value of the Company was less than the carrying amount as of the end of the second quarter of 2020. The Company utilized multiple valuations approaches, including discounted income, change in control premium to parent market price and change in control premium to peer market price to determine the fair value of its goodwill. Each approach was assigned a weight to arrive at the fair value of the reporting unit. Based on the results of the quantitative test, it was determined the carrying amount of a reporting unit exceeded its fair value and that an impairment loss must be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. Based on the results of the quantitative test, the Company recognized an impairment charge equal to the entire amount of its recorded goodwill on the balance sheet at June 30, 2020 totaling $24,754.

Long-term debt	13. Long-term debt: Long-term debt totaled $228,765 at December 31, 2020 and $6,971 at December 31, 2019. For the year ended December 31, long-term debt averaged $147,374 in 2020 and $6,932 in 2019. The increase in long-term debt is primarily attributable to advances taken through the Federal Reserve Board’s PPPLF, whereby loans originated through the PPP program can be pledged as security to facilitate advancements made through the program. As December 31, 2020, we had outstanding borrowing through the program of $176,904 at a rate of 0.35%. The maturity of the PPPLF borrowings have a maturity date based on the term of the PPP loans securing the borrowing, which is 24 months, unless the PPP loans are forgiven prior to the stated maturities. At the end of March 2020, we borrowed $20,000 of term debt from the FHLB to take advantage of reductions in general market rates. These funds were used to bolster our liquidity position and provide necessary funding for new loans. The amount of the term debt was spread over three, five and seven-year maturities. The FHLB borrowing had a weighted average rate of 0.90% and weighted average life of five years. As a FHLB member, we are required to buy a portion of stock in FHLB for each advance. The adjusted weighted average cost of the borrowing decreases to 0.57% considering the addition of the dividend rate on the FHLB stock at the time the borrowing was granted. As a result of the merger with CBT Financial Corp. (“CBT”), the Company assumed the subordinated debentures that were recorded as of the October 1, 2017 effective date. A trust issued $5,155 of floating rate trust preferred securities in 2003 as part of a pooled offering of such securities. The interest rate prior to entering into a fixed interest rate swap in 2020 adjusted quarterly to the three-month LIBOR rate plus 2.95%. CBT issued subordinated debentures to the trust in exchange for ownership of all of the common securities of the trust and the proceeds of the offering; the debentures represent the sole asset of the trust. CBT became eligible to redeem the subordinated debentures, in whole but not in part, beginning in 2008 at a price of 100% of face value. The subordinated debentures must be redeemed no later than 2033. In 2005 a trust formed by CBT issued $4,124 of fixed rate trust preferred securities as part of a pooled offering of such securities. CBT issued subordinated debentures to the trust in exchange for ownership of all of the common securities of the trust and the proceeds of the offering; the debentures represent the sole asset of the trust. CBT became eligible to redeem the subordinated debentures, in whole but not in part, beginning in 2010 at a price of 100% of face value. Interest payments on the debentures may be deferred at any time at the election of the Company for up to 20 consecutive quarterly periods. Interest on the debentures will accrue during the extension period, and all accrued principal and interest must be paid at the end of the extension period. During an extension period, the Company may not declare or pay any dividends or distributions on, or redeem, purchase, acquire, or make a liquidation payment with respect to any of the Company’s capital stock. On October 6, 2020, the Company announced the completion of its private placement of $25,000 of its 5.75% Fixed to Floating Rate Subordinated Notes to certain qualified institutional buyers and accredited institutional investors. The Notes will have a maturity date of October 15, 2030 and initially bear interest, payable semi-annually, at a fixed annual rate of 5.75% per annum until October 15, 2025. Commencing on that date, the interest rate applicable to the outstanding principal amount due will be reset quarterly to an interest rate per annum equal to the then current three-month secured overnight financing rate (“SOFR”) plus 563 basis points, payable quarterly until maturity. The Company may redeem the Notes at par, in whole or in part, at its option, anytime beginning on October 15, 2025 COVID-19 Long-term debt consisting of the following advances at December 31, 2020 and 2019 are as follows: Interest Rate Loan Type Maturity Fixed Adjustable 2020 2019 PPPLF May 3, 2022 0.35 % $ 176,904 FHLB March 10, 2023 0.75 % 6,500 FHLB March 10, 2025 0.88 % 7,000 FHLB March 10, 2027 1.07 % 6,500 Subordinated Debt – Trust Preferred I September 17, 2033 3.18 % 4,420 $ 4,229 Subordinated Debt – Trust Preferred II September 15, 2035 1.76 % 2,913 2,742 Subordinated Debt October 15, 2030 5.75 % 24,528 $ 228,765 $ 6,971 Maturities of long-term debt, by contractual maturity, in years subsequent to December 31, 2020 are as follows: 2021 2022 $ 176,904 2023 6,500 2024 2025 7,000 Thereafter 38,361 $ 228,765

Other noninterest income consists of other recurring revenue streams such as commissions from sales of mutual funds and other investments, investment advisor fees from wealth management products, safety deposit box rental fees, and other miscellaneous revenue streams. Commissions from the sale of mutual funds and other investments are recognized on trade date, which is when the Company has satisfied its performance obligation. The Company also receives periodic service fees or trailers from mutual fund companies typically based on a percentage of net asset value. Trailer revenue is recorded over time, usually monthly or quarterly, as net asset value is determined.

Currently, the Bank’s policy is to match 100% of the employee’s voluntary contribution to the plan up to a maximum of 4% of the employees’ compensation. Additionally, the Bank may make discretionary contributions to the plan after considering current profits and business conditions. The amount charged to expense in 2020 and 2019 totaled $523 and $505, respectively. Of these amounts, no discretionary contributions were made in 2020 and 2019. Director Emeritus Plan: Effective November 2, 2011, a Director Emeritus Agreement (the “Agreement”) was entered into by and between the Company, the Bank and certain Directors. In order to promote orderly succession of the Company’s and Bank’s Board of Directors, the Agreement defines the benefits the Company is willing to provide upon the termination of service to those individuals who served as Directors of the Company and Bank as of December 31, 2011, where the Company will pay the Director $15 per year for services performed as a Director Emeritus, which may be increased at the sole discretion of the Board of Directors. The agreement further states that the benefit is to be paid to a Director Emeritus over five years, in 12 monthly installments: • upon termination of service as a Director on or after the age of 65, provided the Director agrees to provide certain ongoing services for Riverview; • upon termination of service as a Director due to a disability prior to age 65; • upon a change of control; or • upon the death of a Director after electing to be a Director Emeritus. Expenses recorded under the terms of this agreement were $75 for each of the years ended December 31, 2020 and 2019, respectively. Deferred Compensation Agreements: The Bank maintains 12 Supplemental Executive Retirement Plan (“SERP”) agreements that provide specified benefits to certain key executives. The agreements were specifically designed to encourage key executives to remain as employees of the Bank. The agreements are unfunded, with benefits to be paid from the Bank’s general assets. After normal retirement, benefits are payable to the executive or his/her beneficiary in equal monthly installments for a period of 15 years for nine of the executives and 20 years for three of the executives. There are provisions for death benefits should a participant die before his/her retirement date. These benefits are also subject to change of control and other provisions. The Bank maintains a “Director Deferred Fee Agreement” (“DDFA”) which allows electing directors to defer payment of their directors’ fees until a future date. In addition, the Bank maintains an “Executive Deferred Compensation Agreement” (“EDCA”) with eight of its current and former executives. This agreement allows the executives of the Bank to defer payment of their base salary, bonus and performance-based compensation until a future date. For both types of deferred fee agreements during the deferral period, the estimated present value of the future benefits is accrued over the effective dates of the agreements using an interest factor that is evaluated and approved by the compensation committee of the Board of Directors on an annual basis. The agreements are unfunded, with benefits to be paid from the Bank’s general assets. The accrued benefit obligations for all the plans total $4,582 at December 31, 2020 and $4,862 at December 31, 2019 and are included in other liabilities. Expenses relating to these plans totaled $242 and $643 in the years ended December 31, 2020 and 2019, respectively. 2009 Stock Option Plan: The Company has a nonqualified stock option plan to advance the development, growth and financial condition of the Company.

As of December 31, 2020, the Company had no unrecognized compensation expense associated with the stock options since all of the options granted prior to 2018 were fully vested in 2017 as a result of the change in control associated with the merger with CBT . 2019 Equity Incentive Plan: The Company has a non-qualified non-qualified non-qualified The duration of the Plan is 10 years from the approval date. The following table summarizes the award activity for the years ended December 31, 2020 and 2019: 2020 2019 Restricted Fair Restricted Fair Outstanding – January 1, 14,929 $ 12.49 — Granted 16,390 9.15 14,929 $ 12.49 Forfeited and retired (2,512 ) 12.49 Awards vested at year-end (7,828 ) 12.49 — Outstanding – December 31, 20,979 $ 9.88 14,929 $ 12.49 Remaining contractual life 1.11 years 2.17 years Restricted stock awards granted in 2020 and 2019 provide the participant with the right to vote the shares of restricted stock awarded at any time and to receive dividends once the shares are vested. The fair value of the restricted stock awards granted was the closing price of the Company’s common stock as of the date of grant. The expense associated with the grants made December 31, 2020 totaled $150 and $186 for the grants made December 31, 2019 and are respectively expensed over the vesting periods of one year for the awards granted to directors and three equal annual installments for awards granted to employees. The amount expensed for the year ended December 31, 2020 totaled $105 and no expense was recorded for the year ended December 31, 2019. Employee Stock Purchase Plan: The Company has an Employee Stock Purchase Plan (“ESPP”), whereby employees may purchase up to 170,000 shares of common stock of the Company, at a discount of up to a 15%. On April 15, 2015, the Company filed a Registration Statement on Form S-8, S-8, Defined Benefit Pension Plan and Post Retirement Benefit Plan: As a result of the consolidation with Union, the Company took over Union’s noncontributory defined benefit pension plan, which substantially covered all Union employees. The plan benefits were based on average salary and years of service. Union elected to freeze all benefits earned under the plan effective January 1, 2007. The Company also assumed responsibility of Citizens’ noncontributory defined benefit pension plan effective as of the December 31, 2015 merger date. The plan substantially covered all Citizens employees and the plan benefits were based on average salary and years of service. Citizens elected to freeze all benefits earned under the plan effective January 1, 2013. As a result of the merger of equals effective October 1, 2017, the Company assumed responsibility of CBT’s postretirement benefits plan, which is an unfunded postretirement benefit plan covering health insurance costs and postretirement life insurance benefits for certain retirees. The Company accounts for the defined benefit pension plan and the postretirement benefits plan in accordance with FASB ASC Topic 715, “Compensation-Retirement Plans”. This guidance requires the Company to recognize the funded status, which is the difference between the fair value of the plan assets and the projected benefit obligation of the benefit plan. The following table presents the plans’ funded status and the amounts recognized in the Company’s consolidated financial statements for 2020 and 2019. The measurement date, for purposes of these valuations, was December 31, 2020 and 2019.​​​​​​​ Benefit Plans 2020 2019 Obligations and funded status: Change in benefit obligations: Benefit obligation beginning January 1, $ 8,202 $ 7,669 Interest cost 256 313 Benefits paid (547 ) (548 ) Actuarial (gain)/loss 709 768 Benefit obligation at end of year 8,620 8,202 Change in plan assets: Fair value of plan assets at January 1, 8,281 6,310 Adjustment to asset value at January 1 Actual return on plan assets 1,287 1,108 Contributions 2 1,411 Benefits paid (547 ) (548 ) Fair value of plan assets at end of year 9,023 8,281 Funded status included in other liabilities $ 403 $ 79 Amounts related to the plan that have been recognized in accumulated other comprehensive loss but not yet recognized as a component of net periodic pension cost are as follows for the years ended December 31: Benefit Plans 2020 2019 Net loss $ (951 ) $ (1,117 ) Income tax expense (benefit) 200 (235 ) Net amount recognized in other comprehensive loss $ (751 ) $ (882 ) The amount of net periodic benefit credit expected to be accreted in 2021 is $226 for the pension plans.

Analysis of the historic returns on these asset classes and projections of expected future returns were considered in setting the long-term rate of return. • The benefit offered under the postretirement benefits plan is fixed; therefore, the accumulated postretirement benefit obligation is not impacted by health care cost trends or the rate of compensation increase. The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid: Pension Postretirement 2021 $ 535 $ 5 2022 526 5 2023 511 4 2024 508 4 2025 491 4 2026 – 2030 2,310 14 Total $ 4,881 $ 36 The Company’s pension plan asset allocations as of the year ends, by asset category, are as follows: Pension 2020 2019 Cash and cash equivalents 1.51 % 1.64 % Equity 42.62 37.34 Fixed income 55.87 61.02 Total 100.00 % 100.00 % The fair value of the pension plan assets at December 31, 2020 and 2019 by asset category are as follows: 2020 Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Cash and cash equivalents $ 136 $ 136 Mutual fund – equity: Large-cap 378 378 Large-cap 381 381 Mid-cap 478 478 Small-cap 244 244 International growth 651 651 International value 311 311 Large cap growth 774 774 Small / midcap growth 247 247 Mutual funds/ETFs – fixed income: Fixed income – core plus 1,881 1,881 Intermediate duration Long duration – Government credit 2,487 2,487 Long U.S. Treasury – ETF 673 673 Common /collective trusts – equity: Large cap value 382 $ 382 Total assets $ 9,023 $ 8,641 $ 382 2019 Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Cash and cash equivalents $ 136 $ 136 Mutual fund – equity: Large-cap 321 321 Large-cap 343 343 Mid-cap 375 375 Small-cap 152 152 International growth 427 427 International value 214 214 Large cap growth 713 713 Small / midcap growth 202 202 Mutual funds/ETFs – fixed income: Fixed income – core plus 1,928 1,928 Intermediate duration 656 656 Long duration – Government credit 1,812 1,812 Long U.S. Treasury – ETF 657 657 Common /collective trusts – equity: Large cap value 345 $ 345 Total assets $ 8,281 $ 7,936 $ 345 The valuation used is based on quoted market prices provided by an independent third party.

Schedule of Investments [Abstract]
Regulatory matters	20. Regulatory matters: In 2018, the Federal Reserve increased the asset limit to qualify as a small bank holding company from $1 billion to $3 billion. As a result, the Company met the eligibility criteria for a small bank holding company and was exempt from risk-based capital and leverage rules, including Basel III. The Bank’s ability to pay a dividend up to the bank holding company in order to fund the payment of a dividend to shareholders is governed by Section 1302 of the Pennsylvania Banking Code of 1965 which states that the board of directors of an institution may only declare and pay dividends out of accumulated net earnings. Regulatory bodies recently issued guidance reminding bank management of the importance of taking capital preservation actions in these uncertain economic times and encouraging management to remain vigilant on how the current environment impacts their organization’s financial performance, need for capital, and ability to serve customers and communities throughout this crisis. In response to this guidance, the Board of Directors of Riverview decided on July 23, 2020, to suspend the payment of dividends in order to conserve capital. The amount of funds available for transfer from the Bank to the Company in the form of loans and other extensions of credit is also limited. Under Federal Regulation, transfers to any one affiliate are limited to 10.0 percent of capital and surplus. At December 31, 2020, the maximum amount available for transfer from the Bank to the Company in the form of loans amounted to $128,364. At December 31, 2020 and 2019, there were no loans outstanding, nor were any advances made during 2020 and 2019. On October 6, 2020, the Company announced the completion of its private placement of $25,000 of its 5.75% Fixed to Floating Rate Subordinated Notes to certain qualified institutional buyers and accredited institutional investors. The primary purpose of the offering is to enhance the safety and soundness of the Bank’s capital position given the uncertain impact of the COVID-19 The Company and Bank are subject to certain regulatory capital requirements administered by the federal banking agencies, which are defined in Section 38 of the Federal Deposit Insurance Corporation Improvement Act of 1991 (“FDICIA”). 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 Company’s and Bank’s consolidated financial statements. In the event an institution is deemed to be undercapitalized by such standards, FDICIA prescribes an increasing amount of regulatory intervention, including the required institution of a capital restoration plan and restrictions on the growth of assets, branches or lines of business. Further restrictions are applied to the significantly or critically undercapitalized institutions including restrictions on interest payable on accounts, dismissal of management and appointment of a receiver. For well capitalized institutions, FDICIA provides authority for regulatory intervention when the institution is deemed to be engaging in unsafe and unsound practices or receives a less than satisfactory examination report rating. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance The Bank was categorized as “well capitalized” under the regulatory guidance at December 31, 2020 and 2019, based on the most recent notification from the Federal Deposit Insurance Corporation. To be categorized as well capitalized, the Bank must maintain certain minimum Tier I risk-based, total risk-based, Tier I Leverage and Common equity Tier I risk-based capital ratios as set forth in the following tables. The Tier I Leverage ratio is defined as Tier I capital to total average assets less intangible assets. There are no conditions or events since the most recent notification that management believes have changed the Bank’s category. The Bank’s capital ratios and the minimum ratios required for capital adequacy purposes and to be considered well capitalized under the prompt corrective action provisions are summarized below for the years ended December 31, 2020 and December 31, 2019: Actual Minimum Regulatory Capital Ratios under Basel III (with 2.5% capital conservation buffer phase-in) Well Capitalized under Basel III December 31, 2020: Amount Ratio Amount Ratio Amount Ratio Total risk-based capital (to risk-weighted assets: Riverview Bank $ 126,108 14.2 % $ 93,462 > 10.5 % $ 89,011 > 10.0 % Tier 1 capital (to risk-weighted assets): Riverview Bank 114,967 12.9 75,659 > 8.5 71,209 > 8.0 Tier 1 capital (to average total assets): Riverview Bank 114,967 9.8 47,102 > 4.0 58,877 > 5.0 Common equity tier 1 risk-based capital (to risk-weighted assets): Riverview Bank 114,967 12.9 62,308 > 7.0 57,857 > 6.5 Actual Minimum Regulatory Capital Ratios under Basel III (with 2.5% capital conservation buffer phase-in) Well Capitalized under Basel III December 31, 2019: Amount Ratio Amount Ratio Amount Ratio Total risk-based capital (to risk-weighted assets: Riverview Bank $ 104,010 12.4 % $ 88,132 > 10.5 % $ 83,936 > 10.0 % Tier 1 capital (to risk-weighted assets): Riverview Bank 96,405 11.5 71,345 > 8.5 67,148 > 8.0 Tier 1 capital (to average total assets): Riverview Bank 96,405 9.1 42,489 > 4.0 53,112 > 5.0 Common equity tier 1 risk-based capital (to risk-weighted assets): Riverview Bank 96,405 11.5 58,755 > 7.0 54,558 > 6.5 In November 2019, the Federal Financial Institution Examination Council published final rules implementing a simplified measure of capital adequacy for certain banking organizations that have less than $10 billion in total consolidated assets. Under the final rules, which went into effect on January 1, 2020, depository institutions and depository institution holding companies that have less than $10 billion in total consolidated assets and meet other qualifying criteria, including a leverage ratio of greater than 9%, off-balance-sheet assets, are deemed “qualifying community banking organizations” and are eligible to opt into the “community bank leverage ratio framework.” A qualifying community banking organization that elects to use the community bank leverage ratio framework and that maintains a leverage ratio of greater than 9% is considered to have satisfied the generally applicable risk-based and leverage capital requirements under the Basel III rules and, if applicable, is considered to have met the “well capitalized” ratio requirements for purposes of its primary federal regulator’s prompt corrective action rules, discussed below. The final rules include a two-quarter grace period during which a qualifying community banking organization that temporarily fails to meet any of the qualifying criteria, including the greater-than-9% leverage capital ratio requirement, is generally still deemed “well capitalized” so long as the banking organization maintains a leverage capital ratio greater than 8%. A banking organization that fails to maintain a leverage capital ratio greater than 8% is not permitted to use the grace period and must comply with the generally applicable requirements under the Basel III rules and file the appropriate regulatory reports. We are currently evaluating the election to use the community bank leverage ratio framework and may make such an election in the future.

Summary of significant accoun_2

Summary of significant accounting policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Nature of Operations	Nature of Operations: Riverview Financial Corporation, (the “Company” or “Riverview”), a bank holding company incorporated under the laws of Pennsylvania, provides a full range of financial services through its wholly-owned subsidiary, Riverview Bank (the “Bank”). Riverview Bank, with 27 full service offices and three limited purpose offices, is a full-service commercial bank offering a wide range of traditional banking services and financial advisory, insurance and investment services to individuals, municipalities and small to medium sized businesses in the Pennsylvania market areas of Berks, Blair, Bucks, Centre, Clearfield, Cumberland, Dauphin, Huntingdon, Lebanon, Lehigh, Lycoming, Perry, Schuylkill and Somerset Counties. The Bank is state-chartered under the jurisdiction of the Pennsylvania Department of Banking and Securities and the Federal Deposit Insurance Corporation. The Bank’s primary product is loans to small- and medium-sized one-to-four The wealth management and trust divisions did not meet the quantitative thresholds for required segment disclosure in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Bank’s 30 community banking offices, all similar with respect to economic characteristics, share a majority of the following aggregation criteria: (i) products and services; (ii) operating processes; (iii) customer bases; (iv) delivery systems; and (v) regulatory oversight. Accordingly, they were aggregated into a single operating segment. The Company faces competition primarily from commercial banks, thrift institutions and credit unions within the Central, Northern, Southwestern and Southeastern Pennsylvania markets, many of which are substantially larger in terms of assets and capital. In addition, mutual funds and security brokers compete for various types of deposits, and consumer, mortgage, leasing and insurance companies compete for various types of loans and leases. Principal methods of competing for banking and permitted nonbanking services include price, nature of product, quality of service and convenience of location. The Company and the Bank are subject to regulations of certain federal and state regulatory agencies and undergo periodic examinations.
Basis of presentation	Basis of presentation: The consolidated financial statements of the Company have been prepared in conformity with GAAP, Regulation S-X The operating results and financial position of the Company for the year ended as of December 31, 2020, are not necessarily indicative of the results of operations and financial position that may be expected in the future. This is especially true given the outbreak of the Coronavirus (“COVID-19”) pandemic which has adversely affected the Company’s business results of operations and financial condition in 2020. The impact of the pandemic on Riverview’s financial results is evolving and uncertain. The Company expects its net interest income and non-interest COVID-19 COVID-19
Estimates	Estimates: To prepare financial statements in conformity with accounting principles generally accepted in the United States of America management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ.
Investment securities	Investment securities: Investment securities are classified and accounted for as either held-to-maturity, available-for-sale, held-to Held-to-maturity available-for-sale Available-for-sale available-for-sale Management evaluates each investment security at least quarterly, to determine if a decline in fair value below its amortized cost is an other-than-temporary impairment (“OTTI”), and more frequently when economic or market concerns warrant an evaluation. Factors considered in determining whether an other-than-temporary impairment was incurred include: (i) the length of time and the extent to which the fair value has been less than amortized cost; (ii) the financial condition and near-term prospects of the issuer; (iii) whether a decline in fair value is attributable to adverse conditions specifically related to the security or specific conditions in an industry or geographic area; (iv) the credit-worthiness of the issuer of the security; (v) whether dividend or interest payments have been reduced or have not been made; (vi) an adverse change in the remaining expected cash flows from the security such that the Company will not recover the amortized cost of the security; (vii) whether management intends to sell the security; and (viii) if it is more likely than not that management will be required to sell the security before recovery. If a decline is judged to be other-than-temporary, the individual security is written-down to fair value with the credit related component of the write-down included in earnings and the non-credit
Loans held for sale	Loans held for sale: Loans held for sale consist of one-to-four
Loans, net	Loans, net: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at their outstanding unpaid principal balances, net of deferred fees or costs. Interest income is accrued on the principal amount outstanding. Loan origination fees, net of certain direct origination costs, are deferred and recognized over the contractual life of the related loan as an adjustment to yield using the effective interest method. Premiums and discounts on purchased loans are amortized as adjustments to interest income using the effective interest method. Delinquency fees are recognized in income when chargeable, assuming collectability is reasonably assured. Transfers of financial assets, which include loan participation sales, are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when: (i) the assets have been isolated from the Company; (ii) 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 (iii) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. The loan portfolio is segmented into business, construction and retail loans. Business loans consist of commercial and commercial real estate loans. Construction loans consist of both commercial and residential loans. Retail loans consist of residential real estate and other consumer loans.​​​​​​​ The Company makes commercial loans for real estate development and other business purposes required by the customer base. The Company’s credit policies determine advance rates against the different forms of collateral that can be pledged against commercial loans. Typically, the majority of loans will be limited to a percentage of their underlying collateral values such as real estate values, equipment, eligible accounts receivable and inventory. Individual loan advance rates may be higher or lower depending upon the financial strength of the borrower and/or term of the loan. The assets financed through commercial loans are used within the business for its ongoing operation. Repayment of these kinds of loans generally comes from the cash flow of the business or the ongoing conversion of assets. Commercial real estate loans include long-term loans financing commercial properties. Repayment of these loans is dependent upon either the ongoing cash flow of the borrowing entity or the resale of or lease of the subject property. Commercial real estate loans typically require a loan to value of not greater than 80% and vary in terms. Commercial and commercial real estate loans generally have higher credit risk compared to residential mortgage loans and consumer loans, as they typically involve larger loan balances concentrated with single borrowers or groups of borrowers. In addition, the payment expectations on loans secured by income-producing properties typically depend on the successful operations of the related business and thus may be subject to a greater extent to adverse conditions in the real estate market and in the general economy. Loans secured by commercial real estate generally have larger balances and involve a greater degree of risk than one-to-four Residential mortgages, including home equity loans, are secured by the borrower’s residential real estate in either a first or second lien position. Residential mortgages have varying loan rates depending on the financial condition of the borrower and the loan to value ratio. Residential mortgages may have amortizations up to 30 years. Consumer loans include installment loans, car loans, and overdraft lines of credit. The majority of these loans are secured. Consumer loans may entail greater risk than do residential mortgage loans, particularly in the case of consumer loans that are unsecured or secured by assets that depreciate rapidly, such as motor vehicles. In the latter case, repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment for the outstanding loan and a small remaining deficiency often does not warrant further substantial collection efforts against the borrower. Consumer loan collections depend on the borrower’s continuing financial stability, and therefore are likely to be adversely affected by various factors, including job loss, divorce, illness or personal bankruptcy. Furthermore, the application of various federal and state laws, including federal and state insolvency laws, may limit the amount that can be recovered on such loans.
Leases	Leases: The Company’s primary leasing activities relate to certain real estate leases entered into in support of the Company’s branch and back office operations. The Company’s branch locations operating under lease agreements have all been designated as operating leases. In addition, the Company leases certain equipment under operating leases. The Company does not have leases designated as finance leases. The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use available at commencement date in determining the present value of lease payments.

Off-balance sheet financial instruments	Off-balance In the ordinary course of business, the Company enters into off-balance off-balance
Nonperforming assets	Nonperforming assets: Nonperforming assets consist of nonperforming loans and other real estate owned. Nonperforming loans include nonaccrual loans, troubled debt restructured loans and accruing loans past due 90 days or more. Past due status is based on contractual terms of the loan. Generally, a loan is classified as nonaccrual when it is determined that the collection of all or a portion of interest or principal is doubtful or when a default of interest or principal has existed for 90 days or more, unless the loan is well secured and in the process of collection. When a loan is placed on nonaccrual, interest accruals are discontinued, and uncollected accrued interest is reversed against income in the current period. Interest collections after a loan has been placed on nonaccrual status are credited to the principal balance. Interest earned that would have been recognized is credited to income over the remaining life of the loan using the effective yield method if the nonaccrual loan is returned to performing status. A nonaccrual loan is returned to performing status when the loan is current as to principal and interest and has performed according to the contractual terms for a minimum of six months. Troubled debt restructured loans are loans with original terms, interest rate, or both, that have been modified as a result of a deterioration in the borrower’s financial condition and a concession has been granted that the Company would not otherwise consider. Unless on nonaccrual, interest income on these loans is recognized when earned, using the interest method. The Company offers a variety of modifications to borrowers that would be considered concessions. The modification categories offered can generally fall within the following categories: • Rate Modification — A modification in which the interest rate is changed to a below market rate. • Term Modification — A modification in which the maturity date, timing of payments or frequency of payments is changed. • Interest Only Modification — A modification in which the loan is converted to interest only payments for a period of time. • Payment Modification — A modification in which the dollar amount of the payment is changed, other than an interest only modification described above. • Combination Modification — Any other type of modification, including the use of multiple categories above. In March 2020, a joint policy statement was issued by federal and state regulatory agencies to clarify that short-term loan modifications made in good-faith to provide temporary payment relief to borrowers directly impacted by COVID-19 The Company segments loans into risk categories based on relevant information about the ability of borrowers to service their debt such as current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. Loans are individually analyzed for credit risk by classifying them within the Company’s internal risk rating system. The Company’s risk rating classifications are defined as follows: • Pass — A loan to borrowers with acceptable credit quality and risk that is not adversely classified as Substandard, Doubtful, Loss or designated as Special Mention. • Special Mention — A loan that has potential weaknesses that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or in the institution’s credit position at some future date. Special Mention loans are not adversely classified since they do not expose the Company to sufficient risk to warrant adverse classification. • Substandard — A loan that is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. • Doubtful — A loan classified as Doubtful has all the weaknesses inherent in one classified Substandard with the added characteristic that the weaknesses make the collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. • Loss — A loan classified as Loss is considered uncollectible and of such little value that its continuance as a bankable loan is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be effected in the future. Other real estate owned is comprised of properties acquired through foreclosure proceedings or in-substance in-substance
Allowance for loan losses	Allowance for loan losses: The allowance for loan losses represents management’s estimate of losses inherent in the loan portfolio as of the balance sheet date. The allowance for loan losses account is maintained through a provision for loan losses charged to earnings. Loans, or portions of loans, determined to be confirmed losses are charged against the allowance account and subsequent recoveries, if any, are credited to the account. A loss is considered confirmed when information available at the financial statement date indicates the loan, or a portion thereof, is uncollectible. Nonaccrual, troubled debt restructured, and loans deemed impaired at the time of acquisition are reviewed monthly to determine if carrying value reductions are warranted or if these classifications should be changed. Consumer loans are considered losses and charged-off Management evaluates the adequacy of the allowance for loan losses account quarterly. This assessment is based on past charge-off The allowance for loan losses is maintained at a level believed to be adequate to absorb probable credit losses related to specifically identified loans, as well as probable incurred losses inherent in the remainder of the loan portfolio as of the balance sheet date. The allowance for loan losses consists of an allocated element and an unallocated element. The allocated element consists of a specific allowance for impaired loans individually evaluated under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 310, “Receivables,” and a formula portion for loss contingencies on those loans collectively evaluated under FASB ASC 450, “Contingencies.” A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. All amounts due according to the contractual terms means that both the contractual interest and principal payments of a loan will be collected as scheduled in the loan agreement. Factors considered by management in determining impairment include payment status, ability to pay 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 The formula portion of the allowance for loan losses relates to large pools of smaller-balance homogeneous loans and those identified loans considered not individually impaired having similar characteristics as these loan pools. Loss contingencies for each of the major loan pools are determined by applying a total loss factor to the current balance outstanding for each individual pool. The total loss factor is comprised of a historical loss factor using a loss migration method plus qualitative factors, which adjust the historical loss factor for changes in trends, conditions and other relevant factors that may affect repayment of the loans in these pools as of the evaluation date. Loss migration involves determining the percentage of each pool that is expected to ultimately result in loss based on historical loss experience. Historical loss factors are based on the ratio of net loans charged-off charge-off charge-off The unallocated element, if any, is used to cover inherent losses that exist as of the evaluation date, but which have not been identified as part of the allocated allowance using the above impairment evaluation methodology due to limitations in the process. One such limitation is the imprecision of accurately estimating the impact current economic conditions will have on historical loss rates. Variations in the magnitude of impact may cause estimated credit losses associated with the current portfolio to differ from historical loss experience, resulting in an allowance that is higher or lower than the anticipated level. Management establishes the unallocated element of the allowance by considering environmental risks similar to the ones used for determining the qualitative factors. Management continually monitors trends in historical and qualitative factors, including trends in the volume, composition and credit quality of the portfolio. The reasonableness of the unallocated element is evaluated through monitoring trends in its level to determine if changes from period to period are directionally consistent with changes in the loan portfolio. Management believes the level of the allowance for loan losses was adequate to absorb probable credit losses as of December 31, 2020.
Premises and equipment, net	Premises and equipment, net: Land is stated at cost. Premises, equipment and leasehold improvements are stated at cost less accumulated depreciation and amortization. The cost of routine maintenance and repairs is expensed as incurred. The cost of major replacements, renewals and betterments is capitalized. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation and amortization are eliminated, and any resulting gain or loss is reflected in noninterest income. computed principally using the straight-line method based on the following estimated useful lives of the related assets, or in the case of leasehold improvements, to the expected terms of the leases, if shorter: Premises and leasehold improvements 7 Leasehold improvements 10 Furniture, fixtures and 3
Business combinations, goodwill and other intangible assets, net	Business combinations, goodwill and other intangible assets, net: The Company accounts for its acquisitions using the purchase accounting method. Purchase accounting requires the total purchase price to be allocated to the estimated fair values of assets acquired and liabilities assumed, including certain intangible assets that must be recognized. Typically, this allocation results in the purchase price exceeding the fair value of net assets acquired, which is recorded as goodwill. Core deposit intangibles are a measure of the value of checking, money market and savings deposits acquired in business combinations accounted for under the purchase method. Core deposit intangibles and other identified intangibles with finite useful lives are amortized using the sum of the year’s digits over their estimated useful lives of up to ten years. Loans that the Company acquires in connection with acquisitions are recorded at fair value with no carryover of the related allowance for credit losses. Fair value of the loans involves estimating the amount and timing of principal and interest cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. The excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is recognized into interest income over the remaining life of the loan. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the non-accretable non-accretable non-accretable non-accretable The Company accounts for performing loans acquired in business combinations using the contractual cash flows method of recognizing discount accretion based on the acquired loans’ contractual cash flows. Purchased performing loans are recorded at fair value, including a credit discount. The fair value discount is accreted as an adjustment to yield over the estimated lives of the loans. There is no allowance for loan losses established at the acquisition date for purchased performing loans. A provision for loan losses is recorded for any further deterioration in these loans subsequent to the acquisition. Customer list intangibles are also included in intangible assets as a result of the purchase of the wealth management companies. These intangibles are amortized as an expense over Goodwill and other intangible assets are tested for impairment annually during the fourth quarter of each year or when circumstances arise which are considered to be a triggering event indicating impairment may have occurred. In making this assessment that impairment has occurred, management considers a number of factors including, but not limited to, operating results, business plans, economic projections, anticipated future cash flows, and current market data. There are inherent uncertainties related to these factors and management’s judgment in applying them to the analysis of impairment. Changes in economic and operating conditions, as well as other factors, could result in impairment in future periods. Any impairment losses arising from such testing would be reported in the Consolidated Statements of Income and Comprehensive Income as a separate line item within operations. The Company recognized an impairment charge equal to the entire amount of its recorded goodwill on the balance sheet at June 30, 2020 totaling $24,754. For additional disclosure related to the goodwill impairment charge refer to the note entitled “Goodwill” in the Notes to Consolidated Financial Statements. There were no impairment losses recognized as a result of periodic impairment testing for the year ended December 31, 2019.

Bank owned life insurance	Bank owned life insurance: The Company invests in bank owned life insurance (“BOLI”) as a source of funding for employee benefit expenses. BOLI involves the purchasing of life insurance by the Bank on certain of its directors and employees. The Bank is the owner and beneficiary of the policies. This life insurance investment is carried at the cash surrender value of the underlying policies and is included in other assets. Income from increases in cash surrender value of the policies is included in noninterest income.
Pension and post-retirement benefit plans	Pension and post-retirement benefit plans: The Company sponsors various pension plans covering substantially all employees. The Company also provides post-retirement benefit plans other than pensions, consisting principally of life insurance benefits, to eligible retirees. The liabilities and annual income or expense of the Company’s pension and other post-retirement benefit plans are determined using methodologies that involve several actuarial assumptions, the most significant of which are the discount rate and the long-term rate of asset return, based on the market-related value of assets. The fair values of plan assets are determined based on prevailing market prices or estimated fair value for investments with no available quoted prices.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities: The Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. As of and for the year ended December 31, 2020, the Company’s derivative instruments and hedging activities consisted entirely of interest rate swap hedges on its holdings of trust preferred securities. These interest rate swaps are designated as cash flow hedges and involve the receipt of variable rate amounts from a counterparty in exchange for the Company making fixed payments. A cash flow hedge is a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Cash flows on hedges are classified in the consolidated statements of cash flows the same as the cash flows of the items being hedged. The Company formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions at the inception of the hedging relationship. This documentation includes linking fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Company discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as other income. When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in other comprehensive income are amortized into earnings over the same periods which the hedged transaction will affect earnings. The Company is exposed to losses if a counterparty fails to make its payments under a contract in which the Company is in the net receiving position. The Company anticipates that the counterparties will be able to fully satisfy their obligations under the agreements. The contract to which the Company is a party settles monthly.
Statements of Cash Flows	Statements of Cash Flows The Consolidated Statements of Cash Flows are presented using the indirect method. For purposes of cash flow, cash and cash equivalents include cash on hand, cash items in the process of collection, noninterest-bearing and interest-bearing deposits in other banks and federal funds sold.
Fair value of financial instruments	Fair value of financial instruments: The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosure under GAAP. Fair value estimates are calculated without attempting to estimate the value of anticipated future business and the value of certain assets and liabilities that are not considered financial. Accordingly, such assets and liabilities are excluded from disclosure requirements. In accordance with FASB ASC 820, “Fair Value Measurements and Disclosures”, fair value is the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets. In many cases, these values cannot be realized in immediate settlement of the instrument. Current fair value guidance provides a consistent definition of fair value, which focuses on exit price in an orderly transaction that is not a forced liquidation or distressed sale between participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions. In accordance with GAAP, the Company groups its assets and liabilities, generally measured at fair value, into three levels based on market information or other fair value estimates in which the assets and liabilities are traded or valued, and the reliability of the assumptions used to determine fair value. These levels include: • Level 1: Unadjusted quoted prices of identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. • Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. The following methods and assumptions were used by the Company to construct the summary table containing the fair values and related carrying amounts of financial instruments in the Note entitled “Fair value of financial instruments” in the Notes to the Consolidated Financial Statements. Cash and cash equivalents: The carrying values of cash and cash equivalents as reported on the balance sheet approximate fair value. Investment securities available-for-sale: The fair values of debt securities are based on pricing from a matrix pricing model. Loans held for sale: The fair values of loans held for sale are based upon current delivery prices in the secondary mortgage market. Net Loans: Exit price observations are obtained from an independent third-party using its proprietary valuation model and methodology and may not reflect actual or prospective market valuations. The valuation is based on the probability of default, loss given default, recovery delay, prepayment, and discount rate assumptions. The new methodology is a result of the adoption of ASU No. 2016-01. Adjustable-rate loans that reprice frequently and with no significant credit risk, fair values are based on carrying values. The fair values of other non-impaired In conjunction with the mergers, the loans purchased were recorded at their acquisition date fair value. In order to record the loans at fair value, management made three different types of fair value adjustments. A market rate adjustment was made to adjust for the movement in market interest rates, irrespective of credit adjustments, compared to the stated rates of the acquired loans. A credit adjustment was made on pools of homogeneous loans representing the changes in credit quality of the underlying borrowers from the loan inception to the acquisition date. The credit adjustment on distressed loans represents the portion of the loan balance that has been deemed uncollectible based on the management’s expectations of future cash flows for each respective loan. Impaired loans: The fair value of impaired loans with specific allocations of the allowance for loan losses is generally based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available for similar loans and collateral underlying such loans. Accrued interest receivable: The carrying value of accrued interest receivable as reported on the balance sheet approximates fair value. Other real estate owned: Fair value is commonly based on recent real estate appraisals which are updated no less frequently than annually. Restricted equity securities: The carrying values of restricted equity securities approximate fair value, due to the lack of marketability for these securities. Deposits: The fair values of noninterest-bearing deposits and savings, NOW and money market accounts are the amounts payable on demand at the reporting date. The fair value estimates do not include the benefit that results from such low-cost Short-term borrowings: The carrying values of short-term borrowings approximate fair value. Long-term debt: The fair value of fixed-rate long-term debt is based on the present value of future cash flows. The discount rate used is the current rate offered for long-term debt with the same maturity. Accrued interest payable The carrying value of accrued interest payable as reported on the balance sheet approximates fair value. Interest rate swap hedges: The fair value of the interest rate swap liability is based on an external derivative model using input data as of the valuation date.
Off-balance sheet financial instruments	Off-balance The majority of commitments to extend credit, unused portions of lines of credit and standby letters of credit carry current market interest rates if converted to loans. Because such commitments are generally unassignable of either the Company or the borrower, they only have value to the Company and the borrower. None of the commitments are subject to undue credit risk. The estimated fair values of off-balance off-balance
Loss contingencies	Loss contingencies: Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable, and an amount or range of loss can be reasonably estimated. Management does not believe there now are such matters that will have a material effect on the financial statements.
Advertising	Advertising: The Company follows the policy of charging marketing and advertising costs to expense as incurred. Advertising expense for the years ended December 31, 2020 and 2019 was $369 and $812, respectively.
Income taxes	Income taxes: The Company accounts for income taxes in accordance with the income tax accounting guidance set forth in FASB ASC 740, “Income Taxes”. ASC 740 sets out a consistent framework to determine the appropriate level of tax reserves to maintain for uncertain tax positions. The Company has two accruals for income taxes: (i) an income tax payable representing the estimated net amount currently due to the federal government, net of any reserve for potential audit issues and any tax refunds; and (ii) a deferred federal income tax and related valuation accounts, representing the estimated impact of temporary differences between how the Company recognizes its assets and liabilities under GAAP, and how such assets and liabilities are recognized under federal tax law. Deferred income taxes are provided on the balance sheet method whereby deferred tax assets are recognized for deductible temporary differences and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax basis. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the effective date. A tax position is recognized as a benefit only if it is more likely than not that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that has a likelihood of being realized on examination of more than 50 percent. For tax positions not meeting the more likely than not threshold, no tax benefit is recorded. Under the more likely than not threshold guidelines, the Company believes no significant uncertain tax positions exist, either individually or in the aggregate, that would give rise to the non-recognition two-year As applicable, the Company recognizes accrued interest and penalties assessed as a result of a taxing authority examination through income tax expense. The Company files consolidated income tax returns in the United States of America and various states’ jurisdictions. With limited exception, the Company is no longer subject to federal and state income tax examinations by taxing authorities for years before 2017.
Other comprehensive income (loss)	Other comprehensive income (loss): The components of other comprehensive income (loss) and their related tax effects are reported in the Consolidated Statements of Income and Comprehensive Income (Loss). The accumulated other comprehensive income (loss) included in the Consolidated Balance Sheets relates to net unrealized gains and losses on investment securities available-for-sale, December 31 2020 2019 Net unrealized gain on investment securities available-for-sale $ 1,962 $ 676 Income tax expense 412 142 Net of income taxes 1,550 534 Benefit plan adjustments (951 ) (1,117 ) Income tax benefit (200 ) (235 ) Net of income taxes (751 ) (882 ) Derivative adjustments 172 Income tax expense 36 Net of income taxes 136 Accumulated other comprehensive income (loss) $ 935 $ (348 ) Other comprehensive income and related tax effects for the years ended December 31, 2020 and 2019 are as follows: Year ended December 31 2020 2019 Unrealized gain on investment securities available-for-sale $ 2,101 $ 2,837 Net (gain) loss on the sale of investment securities available-for-sale(1) (815 ) 22 Benefit plans: Amortization of actuarial loss(2) 111 104 Actuarial gain (loss) 55 (88 ) Net change in benefit plan liabilities 166 16 Net change in derivative fair value 172 Other comprehensive income gain before taxes 1,624 2,875 Income tax expense 341 604 Other comprehensive income $ 1,283 $ 2,271 (1) Represents amounts reclassified out of accumulated comprehensive income and included in gains on sale of investment securities on the consolidated statements of income and comprehensive income.

Earnings per share	Earnings (loss) per share: Basic earnings (loss) per share is computed by dividing net income (loss) allocated to common stockholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflect additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. The following table provides a reconciliation between the computation of basic earnings (loss) per share and diluted earnings per share for the years ended December 31, 2020 and 2 0 For the Year Ended December 31 2020 2019 Numerator: Net income $ (21,211 ) $ 4,286 Denominator: Basic 9,258,493 9,167,415 Dilutive options 14,337 Diluted 9,258,493 9,181,752 Earnings (loss) per share: Basic $ (2.29 ) $ 0.47 Diluted $ (2.29 ) $ 0.47 Common stock equivalents outstanding that are anti-dilutive and thus excluded from the calculation of the diluted number of shares represented above were 172,964 in 2020 and 23,700 in 2019.
Stock-based compensation	Stock-based compensation: The Company recognizes all share-based payments to employees in the consolidated statement of operations based on their grant date fair values. The fair value of such equity instruments is recognized as an expense in the historical consolidated financial statements as services are performed. The Company uses the Black-Scholes model to estimate the fair value of stock options on the date of grant. The Black-Scholes model estimates the fair value of employee stock options using a pricing model which takes into consideration the exercise price of the option, the expected life of the option, the current market price and its expected volatility, the expected dividends on the stock and the current risk-free interest rate for the expected life of the option. The Company typically grants stock options to employees with an exercise price equal to the fair value of the shares at the date of grant. The fair value of restricted stock is equivalent to the fair value on the date of grant and is expensed over the vesting period.

Description of Regulatory Requirements for Capital Adequacy Purposes			In November 2019, the Federal Financial Institution Examination Council published final rules implementing a simplified measure of capital adequacy for certain banking organizations that have less than $10 billion in total consolidated assets.
Maximum Threshold Amount for applicability of Simplified measures of Capital Adequacy Rules			$ 10,000,000,000
Description of Other Regulatory Limitations		Under the final rules, which went into effect on January 1, 2020, depository institutions and depository institution holding companies that have less than $10 billion in total consolidated assets and meet other qualifying criteria, including a leverage ratio of greater than 9%, off-balance-sheet exposures of 25% or less of total consolidated assets and trading assets plus trading liabilities of 5% or less of total consolidatedassets, are deemed “qualifying community banking organizations” and are eligible to opt into the “community bank leverage ratio framework.”
Maximum Threshold Amount to maintain in Total Consolidated Assets		$ 10,000,000,000
Bank Regulation Leverage Capital Ratio Undercapitalized Minimum				8
Description of Regulatory Requirements of Prompt Corrective Action Rules				The final rules include a two-quarter grace period during which a qualifying community banking organization that temporarily fails to meet any of the qualifying criteria, including the greater-than-9% leverage capital ratio requirement, is generally still deemed “well capitalized” so long as the banking organization maintains a leverage capital ratio greater than 8%. A banking organization that fails to maintain a leverage capital ratio greater than 8% is not permitted to use the grace period and must comply with the generally applicable requirements under the Basel III rules and file the appropriate regulatory reports.
