Accounting Policies [Abstract]
Basis of Presentation And Summary Of Significant Accounting Policies	(1.) 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, Scott Danahy Naylon, 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 across 45 states. 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 2017 Annual Report on Form 10-K for the year ended December 31, 2017. The results of operations for any interim periods are not necessarily indicative of the results which may be expected for the entire year. 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 The Company has evaluated events and transactions for potential recognition or disclosure through the day the financial statements were issued and determined there were no material recognizable subsequent events. 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 loan 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): 2018 2017 Supplemental information: Cash paid for interest $ 19,803 $ 10,189 Cash paid for income taxes 3,790 8,677 Noncash investing and financing activities: Real estate and other assets acquired in settlement of loans 596 379 Accrued and declared unpaid dividends 4,187 3,637 Increase in net unsettled security purchases — 75 Assets acquired and liabilities assumed in business combinations: Fair value of assets acquired 2,561 812 Fair value of liabilities assumed 128 44 (1.) Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606). In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 is intended to improve the recognition and measurement of financial instruments by requiring equity investments to be measured at fair value with changes in fair value recognized in net income; requiring entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; requiring separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements; eliminating the requirement for entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured and amortized at cost on the balance sheet; and requiring an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. ASU 2016-01 is effective for annual periods and interim periods within those annual periods, beginning after December 15, 2017. The amendments should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption. The adoption of ASU 2016-01, as of January 1, 2018, did not have a significant impact on the Company’s financial statements, except for the fair value disclosures as presented in Note 13 – Fair Value Measurements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments (1.) In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230) – Classification of Certain Cash Receipts and Cash Payments In March 2017, the FASB issued ASU No. 2017-07, Compensation – Retirement Benefits (Topic 715) – Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost In March 2017, the FASB issued ASU No. 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) – Premium Amortization on Purchased Callable Debt Securities In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815) – Targeted Improvements to Accounting for Hedging Activities In February 2018, the FASB issued ASU No. 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220) – Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (1.) Revenue Recognition Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers (“ASC 606”), establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity’s contracts to provide goods or services to customers. The core principle requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those goods or services recognized as performance obligations are satisfied. The majority of our revenue-generating transactions are not subject to ASC 606, including revenue generated from financial instruments, such as our loans, letters of credit, derivatives and investment securities, as well as revenue related to our loan servicing activities, as these activities are subject to other GAAP. Descriptions of our primary revenue-generating activities that are within the scope of ASC 606, which are presented in our income statements as components of noninterest income are as follows: • Transactions and service-based revenues - these include service charges on deposits, investment advisory, and ATM and debit card fees. Revenue is recognized when the transactions occur or as services are performed over primarily monthly or quarterly periods. Payment is typically received in the period the transactions occur or, in some cases, within 90 days of the service period. Fees may be fixed or, where applicable, based on a percentage of transaction size or managed assets. • Insurance income - Insurance commissions are received on the sale of insurance products, and revenue is recognized upon the placement date of the insurance policies. Payment is normally received within the policy period. In addition to placement, SDN also provides insurance policy related risk management services. Revenue is recognized as these services are provided.

At September 30, 2018, the Company had positions in 308 investment securities with a fair value of $503.8 million and a total unrealized loss of $25.1 million that have been in a continuous unrealized loss position for more than 12 months. At September 30, 2018, there were a total of 442 securities positions in the Company’s investment portfolio with a fair value of $291.8 million and a total unrealized loss of $6.1 million that had been in a continuous unrealized loss position for less than 12 months. At December 31, 2017, the Company had positions in 172 investment securities with a fair value of $274.8 million and a total unrealized loss of $7.0 million that had been in a continuous unrealized loss position for more than 12 months. At December 31, 2017, there were a total of 239 securities positions in the Company’s investment portfolio with a fair value of $433.1 million and a total unrealized loss of $4.0 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. The Company reviews investment securities on an ongoing basis for the presence of other than temporary impairment (“OTTI”) with formal reviews performed quarterly. When evaluating debt securities for OTTI, management considers many factors, including: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions, and (4) whether the Company has the intention to sell the debt security or whether it is more likely than not that it will be required to sell the debt security before its anticipated recovery. The assessment of whether OTTI exists involves a high degree of subjectivity and judgment and is based on the information then available to management. There was no impairment recorded during the nine months ended September 30, 2018 and 2017. Based on management’s review and evaluation of the Company’s debt securities as of September 30, 2018, the debt securities with unrealized losses were not considered to be OTTI. As of September 30, 2018, the Company did not intend to sell any of the securities in a loss position and believes that it is not likely that it will be required to sell any such securities before the anticipated recovery of amortized cost. Accordingly, as of September 30, 2018, management has concluded that unrealized losses on its investment securities are temporary and no further impairment loss has been realized in the Company’s consolidated statements of income.

There were no loans past due greater than 90 days and still accruing interest as of September 30, 2018 and December 31, 2017. There were $8 thousand and $11 thousand in consumer overdrafts which were past due greater than 90 days as of September 30, 2018 and December 31, 2017, respectively. Consumer overdrafts are overdrawn deposit accounts which have been reclassified as loans but by their terms do not accrue interest. Troubled Debt Restructurings A modification of a loan constitutes a troubled debt restructuring (“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, 2018 and 2017. There were no loans modified as a TDR within the previous 12 months that defaulted during the nine months ended September 30, 2018 and 2017. For purposes of this disclosure, a loan modified as a TDR is considered to have defaulted when the borrower becomes 90 days past due. Impaired 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 are impaired loans. The following table presents the recorded investment, unpaid principal balance and related allowance of impaired loans as of the dates indicated and average recorded investment and interest income recognized on impaired loans for the nine months ended September 30, 2018 and twelve-month period ended December 31, 2017 (in thousands): Recorded Investment (1) Unpaid Principal Balance (1) Related Allowance Average Recorded Investment Interest Income Recognized September 30, 2018 With no related allowance recorded: Commercial business $ 1,155 $ 2,090 $ — $ 1,307 $ — Commercial mortgage 525 525 — 568 — 1,680 2,615 — 1,875 — With an allowance recorded: Commercial business 1,183 1,183 431 2,931 — Commercial mortgage 1,838 1,838 460 2,132 — 3,021 3,021 891 5,063 — $ 4,701 $ 5,636 $ 891 $ 6,938 $ — December 31, 2017 With no related allowance recorded: Commercial business $ 1,635 $ 2,370 $ — $ 853 $ — Commercial mortgage 584 584 — 621 — 2,219 2,954 — 1,474 — With an allowance recorded: Commercial business 3,853 3,853 2,056 4,468 — Commercial mortgage 2,528 2,528 115 1,516 — 6,381 6,381 2,171 5,984 — $ 8,600 $ 9,335 $ 2,171 $ 7,458 $ — (1) Difference between recorded investment and unpaid principal balance represents partial charge-offs. (5.) 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. The following table sets forth the Company’s commercial loan portfolio, categorized by internally assigned asset classification, as of the dates indicated (in thousands): Commercial Business Commercial Mortgage September 30, 2018 Uncriticized $ 505,865 $ 889,608 Special mention 21,141 10,221 Substandard 10,154 7,278 Doubtful — — Total $ 537,160 $ 907,107 December 31, 2017 Uncriticized $ 429,692 $ 791,127 Special mention 7,120 12,185 Substandard 12,951 7,539 Doubtful — — Total $ 449,763 $ 810,851 The Company utilizes payment status as a means of identifying and reporting problem and potential problem retail loans.

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 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 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. 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, 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 or boats. 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. 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.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	(7.) 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 primarily uses interest rate caps 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 2018, such derivatives were used to hedge the variable cash flows associated with short-term borrowings. 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 three and nine months ended September 30, 2018 and 2017. During the next twelve months, the Company estimates that an additional $29 thousand will be reclassified as a decrease 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.

Share Based Compensation [Abstract]
Share-Based Compensation Plans	(10.) The Company maintains certain stock-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, 2018. Number of Underlying Shares Weighted Average Per Share Grant Date Fair Value RSUs 32,655 $ 28.50 PSUs 14,855 27.25 The grant-date fair value for the RSUs granted during the nine months ended September 30, 2018 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. The number of PSUs that ultimately vest is contingent on achieving specified total shareholder return (“TSR”) 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. The shares will be earned based on the Company’s achievement of a relative TSR performance requirement, on a percentile basis, compared to the SNL Small Cap Bank & Thrift Index over a three-year performance period ended December 31, 2020. The shares earned based on the achievement of the TSR performance requirement, if any, will vest on February 27, 2021 assuming the recipient’s continuous service to the Company. The grant-date fair value of the PSUs granted during the nine months ended September 30, 2018 was determined using the Monte Carlo simulation model on the date of grant, assuming the following (i) expected term of 2.84 years, (ii) risk free interest rate of 2.39%, (iii) expected dividend yield of 2.83% and (iv) expected stock price volatility over the expected term of the TSR award of 21.2%. The Monte Carlo simulation model is a risk analysis method that selects a random value from a range of estimates. During the nine months ended September 30, 2018, the company issued a total of 2,724 shares of common stock in-lieu of cash for the annual retainer of five non-employee directors and granted a total of 7,370 restricted shares of common stock to non-employee directors, of which 3,690 shares vested immediately and 3,680 shares will vest after completion of a one-year service requirement. The market price of the stock and restricted stock on the date of grant was $33.90. The following is a summary of restricted stock awards and restricted stock units activity for the nine months ended September 30, 2018: Number of Shares Weighted Average Market Price at Grant Date Outstanding at beginning of year 130,586 $ 24.32 Granted 54,880 28.89 Vested (23,836 ) 25.74 Forfeited (25,251 ) 11.61 Outstanding at end of period 136,379 $ 28.26 At September 30, 2018, there was $2.0 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 1.9 years. (10.) 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 2018 or 2017. There was no unrecognized compensation expense related to unvested stock options as of September 30, 2018. The following is a summary of stock option activity for the nine months ended September 30, 2018 (dollars in thousands, except per share amounts): Number of Options Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value Outstanding at beginning of year 22,199 $ 18.40 Exercised (17,450 ) 18.38 Expired (4,749 ) 18.50 Outstanding and exercisable at end of period — $ — — $ — The aggregate intrinsic value (the amount by which the market price of the stock on the date of exercise exceeded the market price of the stock on the date of grant) of option exercises for the nine months ended September 30, 2018 and 2017 was $236 thousand and $297 thousand, respectively. The total cash received as a result of option exercises under stock compensation plans for the nine months ended September 30, 2018 and 2017 was $320 thousand and $413 thousand, respectively. The Company amortizes the expense related to stock-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, 2018 2017 2018 2017 Salaries and employee benefits $ 306 $ 248 $ 872 $ 676 Other noninterest expense 32 32 225 209 Total share-based compensation expense $ 338 $ 280 $ 1,097 $ 885

Commitments And Contingencies Disclosure [Abstract]
Commitments And Contingencies	(12.) 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, 2018 December 31, 2017 Commitments to extend credit $ 664,138 $ 661,021 Standby letters of credit 12,707 12,181 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. The Company also 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. Forward sales commitments totaled $6.0 million and $566 thousand at September 30, 2018 and December 31, 2017, respectively. The net change in the fair values of these derivatives was recognized as other noninterest income or other noninterest expense in the consolidated statements of income.

Fair Value Disclosures [Abstract]
Fair Value Measurements	(13.) 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. (13.) 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 impaired loans: Fair value of impaired loans with specific allocations of the allowance for loan losses 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. Impaired 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. (13.) Assets Measured at Fair Value The following tables present for each of the fair-value hierarchy levels the Company’s assets that are measured at fair value on a recurring and non-recurring basis as of the dates indicated (in thousands).

There were no transfers between Levels 1 and 2 during the nine months ended September 30, 2018 and 2017. There were no liabilities measured at fair value on a nonrecurring basis during the nine months ended September 30, 2018 and 2017. The following table presents additional quantitative information about assets measured at fair value on a recurring and nonrecurring basis for which the Company has utilized Level 3 inputs to determine fair value (dollars in thousands).

Changes in Level 3 Fair Value Measurements There were no assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) as of or during the nine months ended September 30, 2018. 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.

Basis Of Presentation And Summary Of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2018
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, Scott Danahy Naylon, 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 across 45 states. 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 2017 Annual Report on Form 10-K for the year ended December 31, 2017. The results of operations for any interim periods are not necessarily indicative of the results which may be expected for the entire year.
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 The Company has evaluated events and transactions for potential recognition or disclosure through the day the financial statements were issued and determined there were no material recognizable subsequent events.
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 loan losses, the carrying value of goodwill and deferred tax assets, and assumptions used in the defined benefit pension plan accounting.
Cash Flow Reporting	Cash Flow Reporting Supplemental cash flow information is summarized as follows for the nine months ended September 30 (in thousands): 2018 2017 Supplemental information: Cash paid for interest $ 19,803 $ 10,189 Cash paid for income taxes 3,790 8,677 Noncash investing and financing activities: Real estate and other assets acquired in settlement of loans 596 379 Accrued and declared unpaid dividends 4,187 3,637 Increase in net unsettled security purchases — 75 Assets acquired and liabilities assumed in business combinations: Fair value of assets acquired 2,561 812 Fair value of liabilities assumed 128 44
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606). In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 is intended to improve the recognition and measurement of financial instruments by requiring equity investments to be measured at fair value with changes in fair value recognized in net income; requiring entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; requiring separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements; eliminating the requirement for entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured and amortized at cost on the balance sheet; and requiring an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. ASU 2016-01 is effective for annual periods and interim periods within those annual periods, beginning after December 15, 2017. The amendments should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption. The adoption of ASU 2016-01, as of January 1, 2018, did not have a significant impact on the Company’s financial statements, except for the fair value disclosures as presented in Note 13 – Fair Value Measurements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments (1.) In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230) – Classification of Certain Cash Receipts and Cash Payments In March 2017, the FASB issued ASU No. 2017-07, Compensation – Retirement Benefits (Topic 715) – Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost In March 2017, the FASB issued ASU No. 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) – Premium Amortization on Purchased Callable Debt Securities In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815) – Targeted Improvements to Accounting for Hedging Activities In February 2018, the FASB issued ASU No. 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220) – Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income
Revenue Recognition	(1.) Revenue Recognition Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers (“ASC 606”), establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity’s contracts to provide goods or services to customers. The core principle requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those goods or services recognized as performance obligations are satisfied. The majority of our revenue-generating transactions are not subject to ASC 606, including revenue generated from financial instruments, such as our loans, letters of credit, derivatives and investment securities, as well as revenue related to our loan servicing activities, as these activities are subject to other GAAP. Descriptions of our primary revenue-generating activities that are within the scope of ASC 606, which are presented in our income statements as components of noninterest income are as follows: • Transactions and service-based revenues - these include service charges on deposits, investment advisory, and ATM and debit card fees. Revenue is recognized when the transactions occur or as services are performed over primarily monthly or quarterly periods. Payment is typically received in the period the transactions occur or, in some cases, within 90 days of the service period. Fees may be fixed or, where applicable, based on a percentage of transaction size or managed assets. • Insurance income - Insurance commissions are received on the sale of insurance products, and revenue is recognized upon the placement date of the insurance policies. Payment is normally received within the policy period. In addition to placement, SDN also provides insurance policy related risk management services. Revenue is recognized as these services are provided.
