The Company provides diversified financial services through its subsidiaries, Five Star Bank, SDN Insurance Agency, LLC (“SDN”), Courier Capital, LLC (“Courier Capital”) and HNP Capital, LLC (“HNP Capital”). The Company offers a broad array of deposit, lending and other financial services to individuals, municipalities and businesses in Western and Central New York through its wholly-owned New York chartered banking subsidiary, Five Star Bank (the “Bank”).

Courier Capital and HNP Capital provide customized investment management, investment consulting and retirement plan services to individuals, businesses, institutions, foundations and retirement plans. Basis of Presentation The consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The accounting and reporting policies conform to U.S. generally accepted accounting principles (“GAAP”). Certain information and footnote disclosures normally included in financial statements prepared in conformity with GAAP have been condensed or omitted pursuant to such rules and regulations. However, in the opinion of management, the accompanying consolidated financial statements reflect all adjustments of a normal and recurring nature necessary for a fair presentation of the consolidated statements of financial condition, income, comprehensive income, changes in shareholders’ equity and cash flows for the periods indicated and contain adequate disclosure to make the information presented not misleading. These consolidated financial statements should be read in conjunction with the Company’s 2019 Annual Report on Form 10-K for the year ended December 31, 2019. The results of operations for any interim periods are not necessarily indicative of the results which may be expected for the entire year. Allowance for Credit Losses On January 1, 2020, the Company adopted Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments ASU 2016-13 also expands the disclosure requirements regarding an entity’s assumptions, models, and methods for estimating the reserve for credit losses. In addition, entities need to disclose the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination. The Company adopted ASU 2016-13 using the modified retrospective approach. Results for the periods beginning after January 1, 2020 are presented under Accounting Standards Codification (“ASC”) 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. The Company recorded a net reduction of retained earnings of $8.7 million upon adoption. The transition adjustment includes an increase in credit-related reserves of $9.6 million, $14 thousand, and $2.1 million for loans, held to maturity investment securities and unfunded commitments, respectively, net of the corresponding increase in deferred tax assets of $3.0 million. The allowance for credit losses is evaluated on a regular basis and This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. a. Portfolio Segmentation (“Pooled Loans”) Portfolio segmentation is defined as the pooling of loans based upon similar risk characteristics such that quantitative methodologies and qualitative adjustment factors for estimating the allowance for credit losses is constructed for each segment. The Company has identified six portfolio segments of loans including Commercial Loans/Lines, Commercial Mortgage, Indirect Loans, Direct Loans, Residential Lines of Credit, and Residential Loans. The allowance for credit losses for Pooled Loans estimate is based upon periodic review of the collectability of the loans quantitatively correlating historical loan experience with reasonable and supportable forecasts using forward looking information. Adjustments to the quantitative evaluation may be made for differences in current or expected qualitative risk characteristics such as changes in: underwriting standards, delinquency level, regulatory environment, economic condition, Company management and the status of portfolio administration including the Company’s Loan Review function. (1.) BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) b. Individually Evaluated Loans The Company establishes a specific reserve for individually evaluated loans which do not share similar risk characteristics with the loans included in the forecasted allowance for credit losses. These individually evaluated loans are removed from the pooling approach discussed above for the forecasted allowance for credit losses, and include nonaccrual loans, troubled debt restructurings (“TDRs”), and other loans deemed appropriate by management. c. Held to Maturity (“HTM”) Debt Securities The Company’s HTM debt securities are also required to utilize the current expected credit losses approach to estimate expected credit losses. The Company’s HTM debt securities included securities that are issued by U.S. government or U.S. government-sponsored enterprises. These securities carry the explicit and/or implicit guarantee of the U.S. government, are widely recognized as “risk free,” and have a long history of zero credit loss. The Company also carries a portfolio of HTM municipal bonds. The Company measures its allowance for credit losses on HTM debt securities on a collective basis by major security type. The estimate is based on historical credit losses, if any, adjusted for current conditions and reasonable and supportable forecasts. The Company considers the nature of the collateral, potential future changes in collateral values and available loss information. d. Available for Sale (“AFS”) Debt Securities For AFS securities in an unrealized loss position, we first assess whether (i) we intend to sell, or (ii) it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. If either case is affirmative, any previously recognized allowances are charged-off and the security's amortized cost is written down to fair value through income. If neither case is affirmative, the security is evaluated to determine whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and any adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Adjustments to the allowance are reported in our income statement as a component of credit loss expense. AFS securities are charged-off against the allowance or, in the absence of any allowance, written down through income when deemed uncollectible by management or when either of the aforementioned criteria regarding intent or requirement to sell is met. e. Accrued Interest Receivable Upon adoption of ASU 2016-13 and its related amendments on January 1, 2020, the Company made the following elections regarding accrued interest receivable: • Presenting accrued interest receivable balances separately within another line item on the statement of financial condition. • Excluding accrued interest receivable that is included in the amortized cost of financing receivables and debt securities from related disclosure requirements. • Continuing our policy to write off accrued interest receivable by reversing interest income. For commercial loans, the write off typically occurs upon becoming 90 days past due. For consumer loans, the write off typically occurs upon becoming 120 days past due. Historically, the Company has not experienced uncollectible accrued interest receivable on its investment securities. However, the Company would generally write off accrued interest receivable by reversing interest income if the Company does not reasonably expect to receive payments. Due to the timely manner in which accrued interest receivables are written off, the amounts of such write offs are immaterial. • Not measuring an allowance for credit losses for accrued interest receivable due to the Company’s policy of writing off uncollectible accrued interest receivable balances in a timely manner, as described above. f. Reserve for Unfunded Commitments The reserve for unfunded commitments (the “Unfunded Reserve”) represents the expected credit losses on off-balance sheet commitments such as unfunded commitments to extend credit and standby letters of credit. However, a liability is not recognized for commitments unconditionally cancellable by the Company. The Unfunded Reserve is recognized as a liability (other liabilities in the consolidated statements of financial condition), with adjustments to the reserve recognized as a provision for credit loss expense in the consolidated statements of income. The Unfunded Reserve is determined by estimating expected future fundings, under each segment, and applying the expected loss rates. Expected future fundings are based on historical averages of funding rates (i.e., the likelihood of draws taken). To estimate future fundings on unfunded balances, current funding rates are compared to historical funding rates. (1.) BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Operating, Accounting and Reporting Considerations related to COVID-19 The COVID-19 pandemic has negatively impacted the global economy, including our operating footprint of Western and Central New York. In response to this crisis, the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act was passed by Congress and signed into law on March 27, 2020. The CARES Act provides an estimated $2.2 trillion to fight the COVID-19 pandemic and stimulate the economy by supporting individuals and businesses through loans, grants, tax changes, and other types of relief. Some of the provisions applicable to the Company include, but are not limited to: • Accounting for Loan Modifications - The CARES Act provides that a financial institution may elect to suspend (1) the application of GAAP for certain loan modifications related to COVID-19 that would otherwise be categorized as a TDR and (2) any determination that such loan modifications would be considered a TDR, including the related impairment for accounting purposes. • Paycheck Protection Program - The CARES Act established the Paycheck Protection Program (“PPP”), an expansion of the Small Business Administration’s (“SBA”) 7(a) loan program and the Economic Injury Disaster Loan Program (“EIDL”), administered directly by the SBA. • Mortgage Forbearance - Under the CARES Act, through the earlier of December 31, 2020, or the termination date of the COVID-19 national emergency, a borrower with a federally backed mortgage loan that is experiencing financial hardship due to COVID-19 may request a forbearance. Also, in response to the COVID-19 pandemic, the Board of Governors of the Federal Reserve System (“FRB”), the Federal Deposit Insurance Corporation (“FDIC”), the National Credit Union Administration (“NCUA”), the Office of the Comptroller of the Currency (“OCC”), and the Consumer Financial Protection Bureau (“CFPB”), in consultation with the state financial regulators (collectively, the “agencies”) issued a joint interagency statement (issued March 22, 2020; revised statement issued April 7, 2020). Some of the provisions applicable to the Company include, but are not limited to: • Accounting for Loan Modifications - Loan modifications that do not meet the conditions of the CARES Act may still qualify as a modification that does not need to be accounted for as a TDR. The agencies confirmed with FASB staff that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not TDRs. This includes short-term (e.g., six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or insignificant delays in payment. • Past Due Reporting - With regard to loans not otherwise reportable as past due, financial institutions are not expected to designate loans with deferrals granted due to COVID-19 as past due because of the deferral. A loan’s payment date is governed by the due date stipulated in the legal agreement. If a financial institution agrees to a payment deferral, these loans would not be considered past due during the period of the deferral. • Nonaccrual Status and Charge-offs - During short-term COVID-19 modifications, these loans generally should not be reported as nonaccrual or as classified. Effective March 23, 2020 through July 9, 2020, for consumer customers, the Bank waived early CD penalty fees for withdrawals up to $20,000 (limited to one penalty-free withdrawal per CD account); eliminated all insufficient funds (overdrafts) and returned item fees; eliminated all Pay by Phone fees; waived all late fees; offered the opportunity for monthly mortgage, home equity loan or home equity line payment relief; offered the opportunity to defer unsecured consumer loans or lines of credit and secured consumer loans and lines of credit payments; and offered unsecured personal loans up to $5,000, up to 60 months at 2.95% APR subject to credit approval (additional terms and conditions may apply). In addition, ATM access fees were reinitiated on September 19, 2020. Reclassifications Certain reclassifications of previously reported amounts have been made to conform to the current year presentation. Such reclassifications did not impact net income or shareholders’ equity as previously reported. Subsequent Events Subordinated Note Issuance On October 7, 2020, the Company completed a private placement of $35.0 million in aggregate principal amount of fixed-to-floating rate subordinated notes due 2030 (the “Notes”) to qualified institutional buyers and accredited institutional investors. The Notes have a maturity date of October 15, 2030 and bear interest, payable semi-annually, at the rate of 4.375% per annum, until October 15, 2025. Commencing on that date, the interest rate will reset quarterly to an interest rate per annum equal to the then current three-month secured overnight financing rate (“SOFR”) plus 4.265%, payable quarterly until maturity. (1.) BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) The Company is entitled to redeem the Notes, in whole or in part, on any interest payment date on or after October 15, 2025, and to redeem the Notes in whole at any time upon certain other specified events. The Company intends to use the net proceeds for general corporate purposes, organic growth and to support regulatory capital ratios at Five Star Bank. In connection with the issuance and sale of the Notes, the Company entered into a registration rights agreement with the purchasers of the Notes pursuant to which the Company has agreed to take certain actions to provide for the exchange of the Notes for subordinated notes that are registered under the Securities Act of 1933, as amended, with substantially the same terms as the Notes. Enterprise Standardization Program In October 2020, the Company announced the planned closure of one additional branch in January 2021. This location was not included in the branch consolidations announced in July, as alternative options were being considered and consolidation was not possible given its significant distance from other Five Star Bank branches. This closure is expected to result in one-time expenses related to severance costs and real estate related charges of approximately $130 thousand in the fourth quarter of 2020. Expected expense savings are anticipated at $340 thousand on an annualized basis. Stock Repurchase Program In November 2020, the Company announced that its Board of Directors approved a stock repurchase program for up to 801,879 shares of its common stock, or approximately 5% of the Company’s outstanding common shares. The repurchase program permits shares to be repurchased in open market transactions and pursuant to any trading plan that may be adopted in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934. The timing and number of shares repurchased will depend on a variety of factors including price, corporate and regulatory requirements, market conditions, and other corporate liquidity requirements and priorities. The repurchase program does not obligate the Company to purchase any shares and it may be extended, modified or discontinued at any time. Use of Estimates The preparation of these financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates relate to the determination of the allowance for credit losses, the carrying value of goodwill and deferred tax assets, and assumptions used in the defined benefit pension plan accounting. Cash Flow Reporting Supplemental cash flow information is summarized as follows for the nine months ended September 30 (in thousands): 2020 2019 Supplemental information: Cash paid for interest $ 23,533 $ 28,672 Cash paid for income taxes 5,656 8,666 Noncash investing and financing activities: Real estate and other assets acquired in settlement of loans 2,966 159 Accrued and declared unpaid dividends 4,534 4,363 Increase in net unsettled security purchases — (2,650 ) Common stock issued for Courier Capital contingent earn-out — 1,151 (1.) BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Recent Accounting Pronouncements In April 2019, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. With respect to Topic 815, Derivatives and Hedging, ASU 2019-04 clarifies that the reclassification of a debt security from Held to Maturity (“HTM”) to Available for Sale (“AFS”) under the transition guidance in ASU No. 2017-12, Derivatives and Hedging (Topic 815) – Targeted Improvements to Accounting for Hedging Activities In March 2020, the FASB issued ASU No. 2020-04, “Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” This ASU provides temporary optional expedients and exceptions to GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative rates, such as SOFR. For instance, entities can elect not to apply certain modification accounting requirements to contracts affected by reference rate reform, if certain criteria are met. An entity that makes this election would not have to remeasure the contracts at the modification date or reassess a previous accounting determination. Entities can also elect various optional expedients that would allow them to continue applying hedge accounting for hedging relationships affected by reference rate reform, if certain criteria are met. Finally, entities can make a one-time election to sell and/or reclassify HTM debt securities that reference an interest rate affected by reference rate reform. ASU 2020-04 is effective March 12, 2020, through December 31, 2022. The Company is in the process of determining which optional expedients to elect, if any, as well as the timing and application of those elections. At this time, the Company does not expect any elections to have a significant impact on its financial statements.

Restructuring And Related Activities [Abstract]
Restructuring Charges	(2.) RESTRUCTURING CHARGES On July 17, 2020, the Bank announced management’s decision to adapt to a full-service branch model to streamline retail branches to better align with shifting customer needs and preferences. The transformation resulted in six branch closures and a reduction in staffing. The announcement was the result of a nine-month comprehensive assessment of all lines of business and functional areas, conducted in partnership with a leading process improvement organization. The data-driven analysis identified, among other things, overlapping service areas, automation opportunities and streamlining of processes and operations that would enhance customer experiences and facilitate the long-term sustainability of current and future branches. The announced consolidations represented about ten percent of the branch network and impacted approximately six percent of the total Company workforce. Where possible, those impacted were offered alternative roles or the opportunity to apply for open positions in other areas of the Company. Separated associates received a comprehensive severance package based on tenure. The Company expects to complete a substantial majority of these actions by December 31, 2020. The Company incurred total pre-tax expense related to the branch closures of approximately $1.6 million, including approximately $0.2 million in employee severance, $0.5 million in lease termination costs and $0.9 million in valuation adjustments on branch facilities. The Company expects $0.7 million of total costs will result in future cash expenditures. The Company recognized all of these expenses during the third quarter of 2020. The Company anticipates annual expense savings of approximately $2.6 million as a result of these branch closures. (2.)

At September 30, 2020, the Company had a position in one investment security with a fair value of $8 thousand and a total unrealized loss of less than $1 thousand that has been in a continuous unrealized loss position for more than 12 months. At September 30, 2020, there were a total of 15 securities positions in the Company’s investment portfolio with a fair value of $83.2 million and a total unrealized loss of $206 thousand that had been in a continuous unrealized loss position for less than 12 months. At December 31, 2019, the Company had positions in 34 investment securities with a fair value of $47.2 million and a total unrealized loss of $659 thousand that had been in a continuous unrealized loss position for more than 12 months. At December 31, 2019, there were a total of 57 securities positions in the Company’s investment portfolio with a fair value of $178.7 million and a total unrealized loss of $1.6 million that had been in a continuous unrealized loss position for less than 12 months. The unrealized loss on investment securities was predominantly caused by changes in market interest rates subsequent to purchase. The fair value of most of the investment securities in the Company’s portfolio fluctuates as market interest rates change. Securities Available for Sale As of September 30, 2020, no allowance for credit losses has been recognized on available for sale securities in an unrealized loss position as management does not believe any of the securities are impaired due to reasons of credit quality. This is based upon our analysis of the underlying risk characteristics, including credit ratings, and other qualitative factors related to our available for sale securities and in consideration of our historical credit loss experience and internal forecasts. The issuers of these securities continue to make timely principal and interest payments under the contractual terms of the securities. Furthermore, management does not have the intent to sell any of the securities classified as available for sale in the table above and believes that it is more likely than not that we will not have to sell any such securities before a recovery of cost. The unrealized losses are due to increases in market interest rates over the yields available at the time the underlying securities were purchased. The fair value is expected to recover as the securities approach their maturity date or repricing date or if market yields for such investments decline. Securities Held to Maturity The Company’s HTM investment securities include debt securities that are issued by U.S. government agencies or U.S. government-sponsored enterprises. These securities carry the explicit and/or implicit guarantee of the U.S. government, are widely recognized as “risk free,” and have a long history of zero credit loss. In addition, the Company’s HTM investment securities include debt securities that are issued by state and local government agencies, or municipal bonds. The Company monitors the credit quality of our municipal bonds through the use of a credit rating agency or by ratings that are derived by an internal scoring model. The scoring methodology for the internally derived ratings is based on a series of financial ratios for the municipality being reviewed as compared to typical industry figures. This information is used to determine the financial strengths and weaknesses of the municipality, which is indicated with a numeric rating. This number is then converted into a letter rating to better match the system used by the credit rating agencies. As of September 30, 2020, $151.6 million of our municipal bonds were rated as an equivalent to Standard & Poor’s A/AA/AAA, with $8.5 million internally rated to be the equivalent of Standard & Poor’s A/AA/AAA rating. Additionally, one municipal bond is rated below investment grade, with a BB+ Standard & Poor’s equivalent rating. The below investment grade bond was recently upgraded from a Standard & Poor’s equivalent rating of BB-, represents exposure of $279 thousand, or 0.18% of the municipal bond portfolio and is closely monitored for repayment. As of September 30, 2020, the Company had no past due or nonaccrual held to maturity investment securities.

The CARES Act was passed by Congress and signed into law on March 27, 2020. The CARES Act established the PPP, an expansion of the SBA’s 7(a) loan program and the EIDL, administered directly by the SBA. The Company had $270.5 million of PPP loans (included in Commercial business above) as of September 30, 2020. In addition, the CARES Act provides that a financial institution may elect to suspend (1) the application of GAAP for certain loan modifications related to COVID-19 that would otherwise be categorized as a TDR and (2) any determination that such loan modifications would be considered a TDR, including the related impairment for accounting purposes. Accordingly, the Company had $526.7 million of loans with modifications related to COVID-19 as of September 30, 2020. The Company elected to exclude AIR from the amortized cost basis of loans disclosed throughout this footnote. As of September 30, 2020 and December 31, 2019, AIR for loans totaled $13.7 million and $9.1 million, respectively, and is included in other assets on the Company’s consolidated statements of financial condition.

LOANS (Continued) Past Due Loans Aging The Company’s recorded investment, by loan class, in current and nonaccrual loans, as well as an analysis of accruing delinquent loans is set forth as of the dates indicated (in thousands): 30-59 Days Past Due 60-89 Days Past Due Greater Than 90 Days Total Past Due Nonaccrual Current Total Loans Nonaccrual with no allowance September 30, 2020 Commercial business $ 139 $ 2 $ — $ 141 $ 2,628 $ 820,842 $ 823,611 $ 894 Commercial mortgage — — — — 3,372 1,200,981 1,204,353 3,175 Residential real estate loans 389 35 — 424 3,305 580,234 583,963 3,305 Residential real estate lines 288 — — 288 207 90,404 90,899 207 Consumer indirect 3,520 566 — 4,086 1,244 808,015 813,345 1,244 Other consumer 126 20 141 287 6 16,410 16,703 6 Total loans, gross $ 4,462 $ 623 $ 141 $ 5,226 $ 10,762 $ 3,516,886 $ 3,532,874 $ 8,831 December 31, 2019 Commercial business $ 361 $ — $ — $ 361 $ 1,177 $ 569,684 $ 571,222 Commercial mortgage 531 — — 531 3,146 1,104,638 1,108,315 Residential real estate loans 929 114 — 1,043 2,484 557,190 560,717 Residential real estate lines 231 37 — 268 102 100,678 101,048 Consumer indirect 3,729 1,019 — 4,748 1,725 815,706 822,179 Other consumer 116 8 6 130 — 15,854 15,984 Total loans, gross $ 5,897 $ 1,178 $ 6 $ 7,081 $ 8,634 $ 3,163,750 $ 3,179,465 There were no loans past due greater than 90 days and still accruing interest as of September 30, 2020 and December 31, 2019. There were $141 thousand and $6 thousand in consumer overdrafts which were past due greater than 90 days as of September 30, 2020 and December 31, 2019, respectively. Consumer overdrafts are overdrawn deposit accounts which have been reclassified as loans but by their terms do not accrue interest. The Company recognized no interest income on nonaccrual loans during the nine months ended September 30, 2020 and 2019. Troubled Debt Restructurings A modification of a loan constitutes a TDR when a borrower is experiencing financial difficulty and the modification constitutes a concession. Commercial loans modified in a TDR may involve temporary interest-only payments, term extensions, reducing the interest rate for the remaining term of the loan, extending the maturity date at an interest rate lower than the current market rate for new debt with similar risk, collateral concessions, forgiveness of principal, forbearance agreements, or substituting or adding a new borrower or guarantor. There were no loans modified as a TDR during the nine months ended September 30, 2020 and 2019. During the third quarter of 2020, the Company discovered that the previously reported 2020 TDR was reported in error. This correction had no impact to any other section within our consolidated financial statements and the Company does not consider this correction to be material to any previously issued consolidated financial statement. There were no loans modified as a TDR within the previous 12 months that defaulted during the nine months ended September 30, 2020 and 2019. For purposes of this disclosure, a loan modified as a TDR is considered to have defaulted when the borrower becomes 90 days Collateral Dependent Loans Management has determined that specific commercial loans on nonaccrual status and all loans that have had their terms restructured in a troubled debt restructuring where repayment is expected to be provided substantially through the operation or sale of the collateral to be collateral dependent loans. The following table presents the amortized cost basis of collateral dependent loans by collateral type as of September 30, 2020 (in thousands): Collateral type Business assets Real property Total September 30, 2020 Commercial business $ 4,287 $ 77 $ 4,364 Commercial mortgage — 14,465 14,465 Total $ 4,287 $ 14,542 $ 18,829 ( 5 .) LOANS (Continued) Credit Quality Indicators The Company categorizes 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 such as the fair value of collateral. The Company analyzes commercial business and commercial mortgage loans individually by classifying the loans as to credit risk. Risk ratings are updated any time the situation warrants. The Company uses the following definitions for risk ratings: Special Mention: Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the Company’s credit position at some future date. Substandard: Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Doubtful: Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loans that do not meet the criteria above that are analyzed individually as part of the process described above are considered “uncriticized” or pass-rated loans and are included in groups of homogeneous loans with similar risk and loss characteristics.

These loans are of higher risk and typically are made on the basis of the borrower’s ability to make repayment from the cash flow of the borrower’s business. Further, the collateral securing the loans may depreciate over time, may be difficult to appraise and may fluctuate in value. The credit risk related to commercial loans is largely influenced by general economic conditions, including the impact of the COVID-19 pandemic on small to mid-sized business in our market area, and the resulting impact on a borrower’s operations or on the value of underlying collateral, if any. Commercial mortgage loans generally have larger balances and involve a greater degree of risk than residential mortgage loans, potentially resulting in higher potential losses on an individual customer basis. Loan repayment is often dependent on the successful operation and management of the properties, as well as on the collateral securing the loan. Economic events, including the impact of the COVID-19 pandemic on the ability of the tenants to pay rent at these properties, or conditions in the real estate market could have an adverse impact on the cash flows generated by properties securing the Company’s commercial real estate loans and on the value of such properties. (5 .) LOANS (Continued) Residential real estate loans (comprised of conventional mortgages and home equity loans) and residential real estate lines (comprised of home equity lines) are generally made based on the borrower’s ability to make repayment from his or her employment and other income but are secured by real property whose value tends to be more easily ascertainable. Credit risk for these types of loans is generally influenced by general economic conditions, including the impact of the COVID-19 pandemic on the employment income of these borrowers, the characteristics of individual borrowers, and the nature of the loan collateral. Consumer indirect and other consumer loans may entail greater credit risk than residential mortgage loans and home equities, particularly in the case of other consumer loans which are unsecured or, in the case of indirect consumer loans, secured by depreciable assets, such as automobiles. In such cases, any repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment of the outstanding loan balance. In addition, consumer loan collections are dependent on the borrower’s continuing financial stability, and thus are more likely to be affected by adverse personal circumstances such as job loss, illness or personal bankruptcy, including the heightened risk that such circumstances may arise as a result of the COVID-19 pandemic. Furthermore, the application of various federal and state laws, including bankruptcy and insolvency laws, may limit the amount which can be recovered on such loans.

Leases [Abstract]
Leases	(6 .) LEASES ASC 842, Leases (“ASC 842”), establishes a right of use model that requires a lessee to record a right of use asset and a lease liability for all leases with terms longer than 12 months. The Company is obligated under a number of non-cancellable operating lease agreements for land, buildings and equipment with terms, including renewal options reasonably certain to be exercised, extending through 2047. One building lease is subleased for terms extending through 2021. The following table represents the consolidated statements of financial condition classification of the Company’s right of use assets and lease liabilities: September 30, December 31, Balance Sheet Location 2020 2019 Operating Lease Right of Use Assets: Gross carrying amount Other assets $ 23,690 $ 23,224 Accumulated amortization Other assets (3,266 ) (1,861 ) Net book value $ 20,424 $ 21,363 Operating Lease Liabilities: Right of use lease obligations Other liabilities $ 21,947 $ 22,800 The weighted average remaining lease term for operating leases was 21.5 years at September 30, 2020 and the weighted-average discount rate used in the measurement of operating lease liabilities was 3.80%. The Company utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term for the discount rate. The following table represents lease costs and other lease information: Three months ended September 30, Nine months ended September 30, 2020 2019 2020 2019 Lease costs: Operating lease costs $ 663 $ 706 $ 2,018 $ 2,096 Variable lease costs (1) 111 112 313 321 Sublease income (12 ) (12 ) (35 ) (35 ) Net lease costs $ 762 $ 806 $ 2,296 $ 2,382 Other information: Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 1,947 $ 1,332 Initial recognition of operating lease right of use assets $ — $ 23,275 Initial recognition of operating lease liabilities $ — $ 23,985 Right of use assets obtained in exchange for new operating lease liabilities $ 470 $ 346 (1) ( 6 .)

Goodwill And Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	(7 .) Goodwill The carrying amount of goodwill totaled $66.1 million as of both September 30, 2020 and December 31, 2019. The Company performs a goodwill impairment test on an annual basis as of October 1st or more frequently if events and circumstances warrant. Banking Non-Banking Total Balance, December 31, 2019 $ 48,536 $ 17,526 $ 66,062 No activity during the period — — — Balance, September 30, 2020 $ 48,536 $ 17,526 $ 66,062 Goodwill is not amortized but, instead, is subject to impairment tests on at least an annual basis, and more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Based on the volatility in the capital markets in 2020 and overall economic conditions as a result of the COVID-19 pandemic accompanied by a decline in the Company’s stock price, a quantitative assessment was performed for the Banking segment in the third quarter of 2020. Based on this quantitative assessment, the Company concluded that goodwill was not impaired for the Banking segment. Based on its qualitative assessment for each of the SDN, Courier Capital and HNP Capital reporting units, the Company concluded that it was more likely than not that goodwill was not impaired as of September 30, 2020. Therefore, no quantitative assessment was deemed necessary as of September 30, 2020. Other Intangible Assets The Company has other intangible assets that are amortized, consisting of core deposit intangibles and other intangibles (primarily related to customer relationships). Gross carrying amount, accumulated amortization and net book value, were as follows (in thousands): September 30, December 31, 2020 2019 Other intangibles assets: Gross carrying amount $ 15,925 $ 15,925 Accumulated amortization (7,925 ) (7,064 ) Net book value $ 8,000 $ 8,861 Amortization expense for total other intangible assets was $280 thousand and $861 thousand for the three and nine months ended September 30, 2020, respectively, and $309 thousand and $948 thousand for the three and nine months ended September 30, 2019, respectively.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	( 8 .) Risk Management Objective of Using Derivatives The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities, and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments. Cash Flow Hedges of Interest Rate Risk The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company uses interest rate caps and interest rate swaps as part of its interest rate risk management strategy. Interest rate caps designated as cash flow hedges involve the receipt of variable amounts from a counterparty if interest rates rise above the strike rate on the contract in exchange for an up-front premium. During the first nine months of 2020 and in 2019, such derivatives were used to hedge the variable cash flows associated with short-term borrowings. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The Company is hedging its exposure to the variability in future cash flows for forecasted transactions over a period of approximately 60 months. As of September 30, 2020, the Company had one outstanding forward starting interest rate derivative with a notional value of $50.0 million that was designated as a cash flow hedge of interest rate risk. The derivative becomes effective in April 2022. For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in accumulated other comprehensive income (loss) and subsequently reclassified into interest expense in the same period(s) during which the hedged transaction affects earnings. Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s borrowings. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. The Company’s cash flow hedge derivatives did not have any hedge ineffectiveness recognized in earnings during the nine months ended September 30, 2020 and 2019. During the next twelve months, the Company estimates that $283 thousand will be reclassified as an increase to interest expense. Interest Rate Swaps The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. These interest rate swaps are simultaneously hedged by offsetting interest rate swaps that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate swaps associated with this program do not meet hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. Credit-risk-related Contingent Features The Company has agreements with certain of its derivative counterparties that contain one or more of the following provisions: (a) if the Company defaults on any of its indebtedness, including a default where repayment of the indebtedness has not been accelerated by the lender, the Company could also be declared in default on its derivative obligations, and (b) if the Company fails to maintain its status as a well-capitalized institution, the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements. Mortgage Banking Derivatives The Company extends rate lock agreements to borrowers related to the origination of residential mortgage loans. To mitigate the interest rate risk inherent in these rate lock agreements when the Company intends to sell the related loan, once originated, as well as closed residential mortgage loans held for sale, the Company enters into forward commitments to sell individual residential mortgages. Rate lock agreements and forward commitments are considered derivatives and are recorded at fair value. ( 8 .)

Share Based Compensation [Abstract]
Share-Based Compensation Plans	(1 1 .) SHARE-BASED COMPENSATION PLANS The Company maintains certain share-based compensation plans, approved by the Company’s shareholders, that are administered by the Management Development and Compensation Committee (the “MD&C Committee”) of the Board. The share-based compensation plans were established to allow for the grant of compensation awards to attract, motivate and retain employees, executive officers and non-employee directors who contribute to the long-term growth and profitability of the Company and to give such persons a proprietary interest in the Company, thereby enhancing their personal interest in the Company’s success. The MD&C Committee approved the grant of restricted stock units (“RSUs”) and performance share units (“PSUs”) shown in the table below to certain members of management during the nine months ended September 30, 2020. Number of Underlying Shares Weighted Average Per Share Grant Date Fair Value RSUs 57,306 $ 25.67 PSUs 23,302 25.63 The grant-date fair value for the RSUs granted during the nine months ended September 30, 2020 is equal to the closing market price of our common stock on the date of grant reduced by the present value of the dividends expected to be paid on the underlying shares. Fifty percent of the PSUs that ultimately vest is contingent on achieving specified return on average equity (“ROAE”) targets relative to the SNL Small Cap Bank & Thrift Index, a market index the MD&C Committee has selected as a peer group for this purpose. These shares will be earned based on the Company’s achievement of a relative ROAE performance requirement, on a percentile basis, compared to the SNL Small Cap Bank & Thrift Index over a three-year three-year The grant-date fair values for both the ROAE and the ROAA portions of PSUs granted during the nine months ended September 30, 2020 are equal to the closing market price of our common stock on the date of grant reduced by the present value of the dividends expected to be paid on the underlying shares. During the nine months ended September 30, 2020, the Company issued a total of 5,403 shares of common stock in-lieu of cash for the annual retainer of four non-employee directors and granted a total of 12,798 restricted shares of common stock to non-employee directors, of which 6,399 shares vested immediately and 6,399 shares will vest after completion of a one-year The following is a summary of restricted stock awards and restricted stock units activity for the nine months ended September 30, 2020: Number of Shares Weighted Average Market Price at Grant Date Outstanding at beginning of year 151,808 $ 27.80 Granted 93,406 24.55 Vested (33,433 ) 28.88 Forfeited (39,406 ) 27.99 Outstanding at end of period 172,375 $ 25.78 At September 30, 2020, there was $2.5 million of unrecognized compensation expense related to unvested restricted stock awards and restricted stock units that is expected to be recognized over a weighted average period of 1.96 years. (1 1 .) SHARE-BASED COMPENSATION PLANS (Continued) The Company uses the Black-Scholes valuation method to estimate the fair value of its stock option awards. There were no stock options awarded during the first nine months of 2020 or 2019. There was no unrecognized compensation expense related to unvested stock options as of September 30, 2020. There was no stock option activity for the nine months ended September 30, 2020. The Company amortizes the expense related to share-based compensation awards over the vesting period. Share-based compensation expense is recorded as a component of salaries and employee benefits in the consolidated statements of income for awards granted to management and as a component of other noninterest expense for awards granted to directors. The share-based compensation expense included in the consolidated statements of income, is as follows (in thousands): Three months ended September 30, Nine months ended September 30, 2020 2019 2020 2019 Salaries and employee benefits $ 261 $ 364 $ 793 $ 825 Other noninterest expense 28 29 197 203 Total share-based compensation expense $ 289 $ 393 $ 990 $ 1,028

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	(1 3 .) COMMITMENTS AND CONTINGENCIES Financial Instruments with Off-Balance Sheet Risk The Company has financial instruments with off-balance sheet risk established in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, elements of credit and interest rate risk extending beyond amounts recognized in the financial statements. 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 and standby letters of credit is essentially the same as that involved with extending loans to customers. The Company uses the same credit underwriting policies in making commitments and conditional obligations as for on-balance sheet instruments. Off-balance sheet commitments consist of the following (in thousands): September 30, 2020 December 31, 2019 Commitments to extend credit $ 973,129 $ 820,282 Standby letters of credit 22,652 21,911 (1 3 .) COMMITMENTS AND CONTINGENCIES (Continued) Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the agreement. Commitments generally have fixed expiration dates or other termination clauses which may require payment of a fee. Commitments may expire without being drawn upon; therefore, the total commitment amounts do not necessarily represent future cash requirements. Each customer’s creditworthiness is evaluated on a case-by-case basis. The amount of collateral obtained, if any, is based on management’s credit evaluation of the borrower. Standby letters of credit are conditional lending commitments issued by the Company to guarantee the performance of a customer to a third party. These standby letters of credit are primarily issued to support private borrowing arrangements. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loan facilities to customers. Unfunded Commitments At September 30, 2020 and December 31, 2019, the allowance for credit losses for unfunded commitments totaled $3.1 million and $0, respectively, and was included in other liabilities on the Company's consolidated statements of financial condition. For the three months ended September 30, 2020 and 2019, credit loss expense for unfunded commitments was $461 thousand and $0, respectively. For the nine months ended September 30, 2020 and 2019, credit loss expense for unfunded commitments was $959 thousand and $0, respectively. Contingent Liabilities and Litigation In the ordinary course of business, there are various threatened and pending legal proceedings against the Company. Management believes that the aggregate liability, if any, arising from such litigation, except for the matter described below, would not have a material adverse effect on the Company’s consolidated financial statements. As previously disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 as filed with the SEC on March 4, 2020 and as disclosed in Part II, Item 1 of this Quarterly Report on Form 10-Q, we are party to an action filed against us on May 16, 2017 by Matthew L. Chipego, Charlene Mowry, Constance C. Churchill and Joseph W. Ewing in the Court of Common Pleas in Philadelphia, Pennsylvania. The plaintiffs seek to represent a putative class of consumers who are alleged to have obtained direct or indirect financing from us for the purchase of vehicles that we later repossessed. The plaintiffs specifically claim that the notices the Bank sent to defaulting consumers after their vehicles were repossessed did not comply with the relevant portions of the Uniform Commercial Code in New York and Pennsylvania and are seeking statutory damages, interest and declaratory relief. The Company is pursuing insurance coverage for these claims, including reimbursement for defense costs. We dispute and believe we have meritorious defenses against these claims and plan to vigorously defend ourselves. If we are unsuccessful in defending ourselves from these claims or if we elect to settle these claims and if our insurer does not insure us against legal costs we incur in excess of our deductible, the result may materially adversely affect our business, results of operations and financial condition.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	(1 4 .) FAIR VALUE MEASUREMENTS Determination of Fair Value – Assets Measured at Fair Value on a Recurring and Nonrecurring Basis Valuation Hierarchy The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. ASC Topic 820, “Fair Value Measurements and Disclosures,” establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. There have been no changes in the valuation techniques used during the current period. The fair value hierarchy is as follows: • Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. • Level 2 - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means. • Level 3 - Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. Transfers between levels of the fair value hierarchy are recorded as of the end of the reporting period. (1 4 .) FAIR VALUE MEASUREMENTS (Continued) In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and the Company’s creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. The Company’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Furthermore, the reported fair value amounts have not been comprehensively revalued since the presentation dates, and therefore, estimates of fair value after the balance sheet date may differ significantly from the amounts presented herein. A more detailed description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. Securities available for sale: Securities classified as available for sale are reported at fair value utilizing Level 2 inputs. For these securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. Derivative instruments: The fair value of derivative instruments is determined using quoted secondary market prices for similar financial instruments and are classified as Level 2 in the fair value hierarchy. Loans held for sale: The fair value of loans held for sale is determined using quoted secondary market prices and investor commitments. Loans held for sale are classified as Level 2 in the fair value hierarchy. Collateral dependent loans: Fair value of collateral dependent loans with specific allocations of the allowance for credit losses – loans is measured based on the value of the collateral securing these loans and is classified as Level 3 in the fair value hierarchy. Collateral may be real estate and/or business assets including equipment, inventory and/or accounts receivable and collateral value is determined based on appraisals performed by qualified licensed appraisers hired by the Company. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Appraised and reported values may be discounted based on management’s historical knowledge, changes in market conditions from the time of valuation, and/or management’s expertise and knowledge of the client and the client’s business. Such discounts are typically significant and result in a Level 3 classification of the inputs for determining fair value. Collateral dependent loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly, based on the same factors identified above. Loan servicing rights: Loan servicing rights do not trade in an active market with readily observable market data. As a result, the Company estimates the fair value of loan servicing rights by using a discounted cash flow model to calculate the present value of estimated future net servicing income. The assumptions used in the discounted cash flow model are those that we believe market participants would use in estimating future net servicing income, including estimates of loan prepayment rates, servicing costs, ancillary income, impound account balances, and discount rates. The significant unobservable inputs used in the fair value measurement of the Company’s loan servicing rights are the constant prepayment rates and weighted average discount rate. Significant increases (decreases) in any of those inputs in isolation could result in a significantly lower (higher) fair value measurement. Although the constant prepayment rate and the discount rate are not directly interrelated, they will generally move in opposite directions. Loan servicing rights are classified as Level 3 measurements due to the use of significant unobservable inputs, as well as significant management judgment and estimation. Other real estate owned (foreclosed assets): Nonrecurring adjustments to certain commercial and residential real estate properties classified as other real estate owned are measured at the lower of carrying amount or fair value, less costs to sell. Fair values are generally based on third party appraisals of the property, resulting in a Level 3 classification. The appraisals are sometimes further discounted based on management’s historical knowledge, changes in market conditions from the time of valuation, and/or management’s expertise and knowledge of the client and client’s business. Such discounts are typically significant and result in a Level 3 classification of the inputs for determining fair value. In cases where the carrying amount exceeds the fair value, less costs to sell, an impairment loss is recognized. Commitments to extend credit and letters of credit: Commitments to extend credit and fund letters of credit are principally at current interest rates, and, therefore, the carrying amount approximates fair value. The fair value of commitments is not material. (1 4 .)

(1 4 .) FAIR VALUE MEASUREMENTS (Continued) Disclosures about Fair Value of Financial Instruments The assumptions used below are expected to approximate those that market participants would use in valuing these financial instruments. Fair value estimates are made at a specific point in time, based on available market information and judgments about the financial instrument, including estimates of timing, amount of expected future cash flows and the credit standing of the issuer. Such estimates do not consider the tax impact of the realization of unrealized gains or losses. In some cases, the fair value estimates cannot be substantiated by comparison to independent markets. In addition, the disclosed fair value may not be realized in the immediate settlement of the financial instrument. Care should be exercised in deriving conclusions about our business, its value or financial position based on the fair value information of financial instruments presented below. The estimated fair value approximates carrying value for cash and cash equivalents, Federal Home Loan Bank (“FHLB”) and Federal Reserve Bank (“FRB”) stock, accrued interest receivable, non-maturity deposits, short-term borrowings and accrued interest payable. The following presents (in thousands) the carrying amount, estimated fair value, and placement in the fair value measurement hierarchy of the Company’s financial instruments as of the dates indicated.

Segment Reporting [Abstract]
Segment Reporting	(1 5 .) The Company has two reportable segments: Banking and Non-Banking. These reportable segments have been identified and organized based on the nature of the underlying products and services applicable to each segment, the type of customers to whom those products and services are offered and the distribution channel through which those products and services are made available. The Banking segment includes all of the Company’s retail and commercial banking operations. The Non-Banking segment includes the activities of SDN, a full-service insurance agency that provides a broad range of insurance services to both personal and business clients, and Courier Capital and HNP Capital, our investment advisor and wealth management firms that provide customized investment management, investment consulting and retirement plan services to individuals, businesses, institutions, foundations and retirement plans. Holding company amounts are the primary differences between segment amounts and consolidated totals and are reflected in the Holding Company and Other column below, along with amounts to eliminate balances and transactions between segments.

Accounting Policies [Abstract]
Nature of Operations	Nature of Operations Financial Institutions, Inc. (the “Company”) is a financial holding company organized in 1931 under the laws of New York State (“New York”). The Company provides diversified financial services through its subsidiaries, Five Star Bank, SDN Insurance Agency, LLC (“SDN”), Courier Capital, LLC (“Courier Capital”) and HNP Capital, LLC (“HNP Capital”). The Company offers a broad array of deposit, lending and other financial services to individuals, municipalities and businesses in Western and Central New York through its wholly-owned New York chartered banking subsidiary, Five Star Bank (the “Bank”). The Bank also has indirect lending network relationships with franchised automobile dealers in the Capital District of New York and Northern and Central Pennsylvania. SDN provides a broad range of insurance services to personal and business clients. Courier Capital and HNP Capital provide customized investment management, investment consulting and retirement plan services to individuals, businesses, institutions, foundations and retirement plans.
Basis of Presentation	Basis of Presentation The consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The accounting and reporting policies conform to U.S. generally accepted accounting principles (“GAAP”). Certain information and footnote disclosures normally included in financial statements prepared in conformity with GAAP have been condensed or omitted pursuant to such rules and regulations. However, in the opinion of management, the accompanying consolidated financial statements reflect all adjustments of a normal and recurring nature necessary for a fair presentation of the consolidated statements of financial condition, income, comprehensive income, changes in shareholders’ equity and cash flows for the periods indicated and contain adequate disclosure to make the information presented not misleading. These consolidated financial statements should be read in conjunction with the Company’s 2019 Annual Report on Form 10-K for the year ended December 31, 2019. The results of operations for any interim periods are not necessarily indicative of the results which may be expected for the entire year.
Allowance for Credit Losses	Allowance for Credit Losses On January 1, 2020, the Company adopted Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments ASU 2016-13 also expands the disclosure requirements regarding an entity’s assumptions, models, and methods for estimating the reserve for credit losses. In addition, entities need to disclose the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination. The Company adopted ASU 2016-13 using the modified retrospective approach. Results for the periods beginning after January 1, 2020 are presented under Accounting Standards Codification (“ASC”) 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. The Company recorded a net reduction of retained earnings of $8.7 million upon adoption. The transition adjustment includes an increase in credit-related reserves of $9.6 million, $14 thousand, and $2.1 million for loans, held to maturity investment securities and unfunded commitments, respectively, net of the corresponding increase in deferred tax assets of $3.0 million. The allowance for credit losses is evaluated on a regular basis and This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. a. Portfolio Segmentation (“Pooled Loans”) Portfolio segmentation is defined as the pooling of loans based upon similar risk characteristics such that quantitative methodologies and qualitative adjustment factors for estimating the allowance for credit losses is constructed for each segment. The Company has identified six portfolio segments of loans including Commercial Loans/Lines, Commercial Mortgage, Indirect Loans, Direct Loans, Residential Lines of Credit, and Residential Loans. The allowance for credit losses for Pooled Loans estimate is based upon periodic review of the collectability of the loans quantitatively correlating historical loan experience with reasonable and supportable forecasts using forward looking information. Adjustments to the quantitative evaluation may be made for differences in current or expected qualitative risk characteristics such as changes in: underwriting standards, delinquency level, regulatory environment, economic condition, Company management and the status of portfolio administration including the Company’s Loan Review function. (1.) BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) b. Individually Evaluated Loans The Company establishes a specific reserve for individually evaluated loans which do not share similar risk characteristics with the loans included in the forecasted allowance for credit losses. These individually evaluated loans are removed from the pooling approach discussed above for the forecasted allowance for credit losses, and include nonaccrual loans, troubled debt restructurings (“TDRs”), and other loans deemed appropriate by management. c. Held to Maturity (“HTM”) Debt Securities The Company’s HTM debt securities are also required to utilize the current expected credit losses approach to estimate expected credit losses. The Company’s HTM debt securities included securities that are issued by U.S. government or U.S. government-sponsored enterprises. These securities carry the explicit and/or implicit guarantee of the U.S. government, are widely recognized as “risk free,” and have a long history of zero credit loss. The Company also carries a portfolio of HTM municipal bonds. The Company measures its allowance for credit losses on HTM debt securities on a collective basis by major security type. The estimate is based on historical credit losses, if any, adjusted for current conditions and reasonable and supportable forecasts. The Company considers the nature of the collateral, potential future changes in collateral values and available loss information. d. Available for Sale (“AFS”) Debt Securities For AFS securities in an unrealized loss position, we first assess whether (i) we intend to sell, or (ii) it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. If either case is affirmative, any previously recognized allowances are charged-off and the security's amortized cost is written down to fair value through income. If neither case is affirmative, the security is evaluated to determine whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and any adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Adjustments to the allowance are reported in our income statement as a component of credit loss expense. AFS securities are charged-off against the allowance or, in the absence of any allowance, written down through income when deemed uncollectible by management or when either of the aforementioned criteria regarding intent or requirement to sell is met. e. Accrued Interest Receivable Upon adoption of ASU 2016-13 and its related amendments on January 1, 2020, the Company made the following elections regarding accrued interest receivable: • Presenting accrued interest receivable balances separately within another line item on the statement of financial condition. • Excluding accrued interest receivable that is included in the amortized cost of financing receivables and debt securities from related disclosure requirements. • Continuing our policy to write off accrued interest receivable by reversing interest income. For commercial loans, the write off typically occurs upon becoming 90 days past due. For consumer loans, the write off typically occurs upon becoming 120 days past due. Historically, the Company has not experienced uncollectible accrued interest receivable on its investment securities. However, the Company would generally write off accrued interest receivable by reversing interest income if the Company does not reasonably expect to receive payments. Due to the timely manner in which accrued interest receivables are written off, the amounts of such write offs are immaterial. • Not measuring an allowance for credit losses for accrued interest receivable due to the Company’s policy of writing off uncollectible accrued interest receivable balances in a timely manner, as described above. f. Reserve for Unfunded Commitments The reserve for unfunded commitments (the “Unfunded Reserve”) represents the expected credit losses on off-balance sheet commitments such as unfunded commitments to extend credit and standby letters of credit. However, a liability is not recognized for commitments unconditionally cancellable by the Company. The Unfunded Reserve is recognized as a liability (other liabilities in the consolidated statements of financial condition), with adjustments to the reserve recognized as a provision for credit loss expense in the consolidated statements of income. The Unfunded Reserve is determined by estimating expected future fundings, under each segment, and applying the expected loss rates. Expected future fundings are based on historical averages of funding rates (i.e., the likelihood of draws taken). To estimate future fundings on unfunded balances, current funding rates are compared to historical funding rates.
Operating, Accounting and Reporting Considerations related to COVID-19	(1.) BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Operating, Accounting and Reporting Considerations related to COVID-19 The COVID-19 pandemic has negatively impacted the global economy, including our operating footprint of Western and Central New York. In response to this crisis, the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act was passed by Congress and signed into law on March 27, 2020. The CARES Act provides an estimated $2.2 trillion to fight the COVID-19 pandemic and stimulate the economy by supporting individuals and businesses through loans, grants, tax changes, and other types of relief. Some of the provisions applicable to the Company include, but are not limited to: • Accounting for Loan Modifications - The CARES Act provides that a financial institution may elect to suspend (1) the application of GAAP for certain loan modifications related to COVID-19 that would otherwise be categorized as a TDR and (2) any determination that such loan modifications would be considered a TDR, including the related impairment for accounting purposes. • Paycheck Protection Program - The CARES Act established the Paycheck Protection Program (“PPP”), an expansion of the Small Business Administration’s (“SBA”) 7(a) loan program and the Economic Injury Disaster Loan Program (“EIDL”), administered directly by the SBA. • Mortgage Forbearance - Under the CARES Act, through the earlier of December 31, 2020, or the termination date of the COVID-19 national emergency, a borrower with a federally backed mortgage loan that is experiencing financial hardship due to COVID-19 may request a forbearance. Also, in response to the COVID-19 pandemic, the Board of Governors of the Federal Reserve System (“FRB”), the Federal Deposit Insurance Corporation (“FDIC”), the National Credit Union Administration (“NCUA”), the Office of the Comptroller of the Currency (“OCC”), and the Consumer Financial Protection Bureau (“CFPB”), in consultation with the state financial regulators (collectively, the “agencies”) issued a joint interagency statement (issued March 22, 2020; revised statement issued April 7, 2020). Some of the provisions applicable to the Company include, but are not limited to: • Accounting for Loan Modifications - Loan modifications that do not meet the conditions of the CARES Act may still qualify as a modification that does not need to be accounted for as a TDR. The agencies confirmed with FASB staff that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not TDRs. This includes short-term (e.g., six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or insignificant delays in payment. • Past Due Reporting - With regard to loans not otherwise reportable as past due, financial institutions are not expected to designate loans with deferrals granted due to COVID-19 as past due because of the deferral. A loan’s payment date is governed by the due date stipulated in the legal agreement. If a financial institution agrees to a payment deferral, these loans would not be considered past due during the period of the deferral. • Nonaccrual Status and Charge-offs - During short-term COVID-19 modifications, these loans generally should not be reported as nonaccrual or as classified. Effective March 23, 2020 through July 9, 2020, for consumer customers, the Bank waived early CD penalty fees for withdrawals up to $20,000 (limited to one penalty-free withdrawal per CD account); eliminated all insufficient funds (overdrafts) and returned item fees; eliminated all Pay by Phone fees; waived all late fees; offered the opportunity for monthly mortgage, home equity loan or home equity line payment relief; offered the opportunity to defer unsecured consumer loans or lines of credit and secured consumer loans and lines of credit payments; and offered unsecured personal loans up to $5,000, up to 60 months at 2.95% APR subject to credit approval (additional terms and conditions may apply). In addition, ATM access fees were reinitiated on September 19, 2020.
Reclassifications	Reclassifications Certain reclassifications of previously reported amounts have been made to conform to the current year presentation. Such reclassifications did not impact net income or shareholders’ equity as previously reported.
Subsequent Events	Subsequent Events Subordinated Note Issuance On October 7, 2020, the Company completed a private placement of $35.0 million in aggregate principal amount of fixed-to-floating rate subordinated notes due 2030 (the “Notes”) to qualified institutional buyers and accredited institutional investors. The Notes have a maturity date of October 15, 2030 and bear interest, payable semi-annually, at the rate of 4.375% per annum, until October 15, 2025. Commencing on that date, the interest rate will reset quarterly to an interest rate per annum equal to the then current three-month secured overnight financing rate (“SOFR”) plus 4.265%, payable quarterly until maturity. (1.) BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) The Company is entitled to redeem the Notes, in whole or in part, on any interest payment date on or after October 15, 2025, and to redeem the Notes in whole at any time upon certain other specified events. The Company intends to use the net proceeds for general corporate purposes, organic growth and to support regulatory capital ratios at Five Star Bank. In connection with the issuance and sale of the Notes, the Company entered into a registration rights agreement with the purchasers of the Notes pursuant to which the Company has agreed to take certain actions to provide for the exchange of the Notes for subordinated notes that are registered under the Securities Act of 1933, as amended, with substantially the same terms as the Notes. Enterprise Standardization Program In October 2020, the Company announced the planned closure of one additional branch in January 2021. This location was not included in the branch consolidations announced in July, as alternative options were being considered and consolidation was not possible given its significant distance from other Five Star Bank branches. This closure is expected to result in one-time expenses related to severance costs and real estate related charges of approximately $130 thousand in the fourth quarter of 2020. Expected expense savings are anticipated at $340 thousand on an annualized basis.
Stock Repurchase Program	Stock Repurchase Program In November 2020, the Company announced that its Board of Directors approved a stock repurchase program for up to 801,879 shares of its common stock, or approximately 5% of the Company’s outstanding common shares. The repurchase program permits shares to be repurchased in open market transactions and pursuant to any trading plan that may be adopted in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934. The timing and number of shares repurchased will depend on a variety of factors including price, corporate and regulatory requirements, market conditions, and other corporate liquidity requirements and priorities. The repurchase program does not obligate the Company to purchase any shares and it may be extended, modified or discontinued at any time.
Use of Estimates	Use of Estimates The preparation of these financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates relate to the determination of the allowance for credit losses, the carrying value of goodwill and deferred tax assets, and assumptions used in the defined benefit pension plan accounting.

Recent Accounting Pronouncements	(1.) BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Recent Accounting Pronouncements In April 2019, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. With respect to Topic 815, Derivatives and Hedging, ASU 2019-04 clarifies that the reclassification of a debt security from Held to Maturity (“HTM”) to Available for Sale (“AFS”) under the transition guidance in ASU No. 2017-12, Derivatives and Hedging (Topic 815) – Targeted Improvements to Accounting for Hedging Activities In March 2020, the FASB issued ASU No. 2020-04, “Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” This ASU provides temporary optional expedients and exceptions to GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative rates, such as SOFR. For instance, entities can elect not to apply certain modification accounting requirements to contracts affected by reference rate reform, if certain criteria are met. An entity that makes this election would not have to remeasure the contracts at the modification date or reassess a previous accounting determination. Entities can also elect various optional expedients that would allow them to continue applying hedge accounting for hedging relationships affected by reference rate reform, if certain criteria are met. Finally, entities can make a one-time election to sell and/or reclassify HTM debt securities that reference an interest rate affected by reference rate reform. ASU 2020-04 is effective March 12, 2020, through December 31, 2022. The Company is in the process of determining which optional expedients to elect, if any, as well as the timing and application of those elections. At this time, the Company does not expect any elections to have a significant impact on its financial statements.
