Summary of Significant Accounting Policies Text Block	AUBURN NATIONAL BANCORPORATION, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements (Unaudited) NOTE 1 : SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES General Auburn National Bancorporation, Inc. (the “Company”) provides a full range of banking services to individual and corporate customers in Lee County, Alabama and surrounding counties through its wholly owned subsidiary, AuburnBank (the “Bank”). The Company does not have any segments other than banking that are considered material. Ba sis of Presentation and Use of Estimates The unaudited consolidated financial statements in this report have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. Accordingly, these fin ancial statements do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The unaudited consolidated financial statements include, in the opinion of management, all adjustments necessary to present a fa ir statement of the financial position and the results of operations for all periods presented. All such adjustments are of a normal recurring nature. The results of operations in the interim statements are not necessarily indicative of the results of oper ations that the Company and its subsidiaries may achieve for future interim periods or the entire year. For further information, refer to the consolidated financial statements and footnotes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2016 . The unaudited consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Auburn National Bancorporation Capital Trust I is an affiliate of the Company and was included in these unaudite d consolidated financial statements pursuant to the equity method of accounting. Significant intercompany transactions and accounts are eliminated in consolidation. The preparation of financial statements in conformity with U.S. GAAP requires management t o make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the balance sheet date and the reported amounts of revenues and expenses during the reporting period. Ac tual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term include other-than-temporary impairment on investment securities, the determination of the allowance for loan losse s, fair value of financial instruments, and the valuation of deferred tax assets and other real estate owned. Subsequent Events The Company has evaluated the effects of events and transactions through the date of this filing that have occurred subsequen t to September 30, 2017 . The Company does not believe there were any material subsequent events during this period that would have required further recognition or disclosure in the unaudited consolidated financial statements included in this report . Account ing Developments In the first nine months of 2017 , the Company adopted no new accounting guidance .

Basic and Diluted Earnings Per Share [Abstract]
Basic and Diluted Earnings Per Share Text Block	NOTE 2 : BASIC AND DILUTED NET EARNINGS PER SHARE Basic net earnings per share is computed by dividing net earnings by the weighted average common shares outstanding for the respective period . Diluted net earnings per share reflect the potential dilution that could occur upon exercise of securities or other rights for, or convertible into, shares of the Company’s common stock. At September 30, 2017 and 2016 , respectively, the Company had no such securities or rights issued or outstanding, and therefore, no dilutive effect to consider for the diluted earnings per share calculation. The basic and diluted net earnings per share computations for the respective periods are presented below.

Variable interest entities [Abstract]
Variable interest entity [Text Block]	NOTE 3 : VARIABLE INTEREST ENTITIES Generally, a variable interest entity (“VIE”) is a corporation, partnership, trust, or other legal structure that does not have equity investors with substantive or proportional voting rights or has equity investors that do not provide sufficient financial resources for the entity to support its activities. At September 30, 2017 , the Company did not have any consolidated VIEs to disclose but did have one nonconsolidated VIE, discussed below. Tr ust Preferred Securities The Company owns the common stock of a subsidiary business trust, Auburn National Bancorporation Capital Trust I (the “Trust”), which issued mandatorily redeemable preferred capital securities (“trust preferred securities”) in t he aggregate of approximately $7.0 million at the time of issuance. The Trust meets the definition of a VIE of which the Company is not the primary beneficiary; the Trust’s only assets are junior subordinated debentures issued by the Company, which were ac quired by the trust using the proceeds from the issuance of the trust preferred securities and common stock. In October 2016, the Company purchased $4.0 million par amount of outstanding trust preferred securities issued by the Trust. These securities we re sold to us by the FDIC, as re ceiver of a failed bank that previously held the trust preferred securities. The Company used dividends from the Bank to purchase these trust preferred securities and has deemed an equivalent amount of the related junior subordina ted debentures issued by the Company as no longer outstanding. The remaining junior subordinated debentures of approximately $3.2 million are included in long-term debt and the Company’s equity interest of $0.2 million in the Trust is included in other as sets. Interest expense on the junior subordinated debentures that remain outstanding is included in interest expense on long-term debt. The following table summarizes VIEs that are not consolidated by the Company as of September 30, 2017 .

Securities with aggregate fair values of $155.5 million and $137.2 million at September 30, 2017 and December 31, 2016 , respectively, were pledged to secure public deposits, securities sold under agreements to repurchase, Federal Home Loan Bank (“FHLB”) advances, and for other purposes required or permitted by law. Included in other assets are cost-method investments. The carrying amounts of cost-method investments were $1.4 million at September 30, 2017 and December 31, 2016 , respectively.

Gross Unrealized Losses and Fair Value The fair values and gross unrealized losses on securities at September 30, 2017 and December 31, 2016 , respectively, segregated by those securities that have been in an unrealized loss position for less than 12 months and 12 months or longer, are presented below. Less than 12 Months 12 Months or Longer Total Fair Unrealized Fair Unrealized Fair Unrealized (Dollars in thousands) Value Losses Value Losses Value Losses September 30, 2017: Agency obligations $ 9,871 67 15,655 587 $ 25,526 654 Agency RMBS 46,620 375 34,051 799 80,671 1,174 State and political subdivisions 8,164 151 7,710 212 15,874 363 Total $ 64,655 593 57,416 1,598 $ 122,071 2,191 December 31, 2016: Agency obligations $ 20,352 973 — — $ 20,352 973 Agency RMBS 89,062 1,805 — — 89,062 1,805 State and political subdivisions 20,444 734 — — 20,444 734 Total $ 129,858 3,512 — — $ 129,858 3,512 For the securities in the previous table, the Company does not have the intent to sell and has determined it is not more likely than not that the Company will be required to sell the security before recovery of the amortized cost basis, which may be maturity. On a quarterly basis, the Company assesses each security for credit impairment. For debt securities, the Company evaluates, where necessary, whether credit impairment exists by comparing the present value of the expected cash flows to the securi ties’ amortized cost basis. For cost-method investments, the Company evaluates whether an event or change in circumstances has occurred during the reporting period that may have a significant adverse effect on the fair value of the investment. In determi ning whether a loss is temporary, the Company considers all relevant information including: the length of time and the extent to which the fair value has been less than the amortized cost basis; adverse conditions specifically related to the security, an industry, or a geographic area (for example, changes in the financial condition of the issuer of the security, or in the case of an asset-backed debt security, in the financial condition of the underlying loan obligors, including changes in technology or the discontinuance of a segment of the business that may affect the future earnings potential of the issuer or underlying loan obligors of the security or changes in the quality of the credit enhancement); the historical and implied volatility of the f air value of the security; the payment structure of the debt security and the likelihood of the issuer being able to make payments that increase in the future; failure of the issuer of the security to make scheduled interest or principal payments; an y changes to the rating of the security by a rating agency; and recoveries or additional declines in fair value subsequent to the balance sheet date. Agency obligations The unrealized losses associated with agency obligations were primarily driven by ch anges in interest rates and not due to the credit quality of the securities. These securities were issued by U.S. government agencies or government-sponsored entities and did not have any credit losses given the explicit government guarantee or other gover nment support. Agency RMBS The unr ealized losses associated with a gency residential mortgage-backed securities (“ RMBS ”) were primarily driven by changes in interest rates and not due to the credit quality of the securities. These securities were issued by U.S. government agencies or government-sponsored entities and d id not have any credit losses given the explicit government guarantee or other government support . Securities of U.S. states and political subdivisions The unrealized losses asso ciated with securities of U.S. states and political subdivisions were primarily driven by changes in interest rates and were not due to the credit quality of the securities. Some of these securities are guaranteed by a bond insurer, but management did not rely on the guarantee in making its investment decision. These securities will continue to be monitored as part of the Company’s quarterly impairment analysis, but are expected to perform even if the rating agencies reduce the credit rating of the bond i nsurers. As a result, the Company expects to recover the entire amortized cost basis of these securities. Cost-method investments At September 30, 2017 , cost-method investments with an aggregate cost of $1.4 million were not evaluated for impairment because the Company had not identified any events or changes in circumstances that may have a significant adverse effect on the fair value of these cost-method investments. The carrying values of the Company’s inv estment securities could decline in the future if the financial condition of an issuer deteriorates and the Company determines it is probable that it will not recover the entire amortized cost basis for the security. As a result, there is a risk that other -than-temporary impairment charges may occur in the future. Other-Than-Temporarily Impaired Securities Credit-impaired debt securities are debt securities where the Company has written down the amortized cost basis of a security for other-than-temporary impairment and the credit component of the loss is recognized in earnings. At September 30, 2017 and December 31, 2016 , the Company had no credit-impaired debt securities and there were no additions or reductions in the credit loss component of credit-impaired debt securities during the nine months ended September 30, 2017 an d 2016 , respectively . Realized Gains and Losses The following table presents the gross realized gains and losses on sales of securities.

At September 30, 2017 , the Company’s geographic loan distribution was concentrated primarily in Lee County, Alabama , and surrounding areas. In accordance with ASC 310, a portfolio segment is defined as the level at which an entity develops and documents a systematic method for determining its allowance for loan losses. As part of the Company’s quarterly assessment of the allowance, the loan portfolio is disaggregated into the following portfolio segments: commercial and industrial, construction and land development, commercial real estate, residential real estate, and consumer installment. Where appropriate, the Company’s loan portfoli o segments are further disaggregated into classes. A class is generally determined based on the initial measurement attribute, risk characteristics of the loan, and an entity’s method for monitoring and determining credit risk. The following describe the risk characteristics relevant to each of the portfolio segments and classes . Commercial and i ndustrial (“C&I”) — includes loans to finance business operations, equipment purchases, or other needs for small and medium-sized commercial customers. Also inclu ded in this category are loans to finance agricultural production. Generally , the primary source of repayment is the cash flow from business operations and activities of the borrower. Construction and land development (“C&D”) — includes both loans and cr edit lines for the purpose of purchasing, carrying , and developing land into commercial developments or residential subdivisions. Also included are loans and credit lines for construction of residential, multi-family , and commercial buildings. Generally , t he primar y source of repayment is dependent upon the sale or refinance of the real estate collateral. Commercial real estate (“CRE”) — includes loans disaggregated into three classes: (1) owner occupied, (2) multifamily and (3 ) other. Owner occupied – includes loans secured by business facilities to finance business operations, equipment and owner-occupied facilities primarily for small and medium-sized commercial customers. Generally , the primary source of repayment is the cash flow from business oper ations and activities of the borrower, who owns the property. Multi-family – primarily includes loans to finance income-producing multi-family properties . Loans in this class include loans for 5 or more unit residential property and apartments leased to r esidents. Generally , the primary source of repayment is dependent upon income generated from the real estate collateral. The underwriting of these loans takes into consideration the occupancy and rental rates , as well as the financial health of the borrowe r. Other – primarily includes loans to finance income-producing commercial properties that are not owner occupied . Loans in this class include loans for neighborhood retail centers, hotels, medical and professional offices, single retail stores, industrial buildings, and warehouses leased to local businesses . Generally , the primary source of repayment is dependent upon income generated from the real estate collateral. The underwriting of these loans takes into consideration the occupancy and rental rates , as well as the financial health of the borrower. Residential real estate (“RRE”) — includes loans disaggregated into two classes: (1) consumer mortgage and (2) investment property. Consumer mort gage – primarily include s first or second lien mortgages and home equity lines of credit to consumers that are secured by a primary residence or second home. These loans are underwritten in accordance with the Bank’s general loan policies and procedures wh ich require, among other things, proper documentation of each borrower’s financial condition, satisfactory credit history , and property value. Investment property – primarily includes loans to finance income-producing 1-4 family residential properties. Generally , the primary source of repayment is dependent upon income generated from leasing the property securing the loan. The underwriting of these loans takes into consideration the rental rates and property value, as well as the financial health of the borrower. Consumer installment — includes loans to individuals both secured by personal property and unsecured. Loans include personal lines of credit, automobile loans, and other retail loans. These loans are underwritten in a ccordance with the Bank’s general loan policies and procedures which require, among other things, proper documentation of each borrower’s financial condition, satisfactory credit history, and , if applicable, property value. The following is a summary of c urrent, accruing past due , and nonaccrual loans by portfolio segment and class as of September 30, 2017 and December 31, 2016 .

The level of the allowance is based upon management’s evaluation of the loan portfolio, past loan loss experience, current asset quality trends, known and inherent risks in the portfolio, adverse situations that may affect a borrower’s ability to repay (including the timing of future payment), the estimated value of any underlying collateral, composition of the loan po rtfolio, economic conditions, industry and peer bank loan loss rates, and other pertinent factors, including regulatory recommendations. This evaluation is inherently subjective as it requires material estimates including the amounts and timing of future c ash flows expected to be received on impaired loans that may be susceptible to significant change. Loans are charged off, in whole or in part, when management believes that the full collectability of the loan is unlikely. A loan may be partially charged-of f after a “confirming event” has occurred, which serves to validate that full repayment pursuant to the terms of the loan is unlikely. The Company deems loans impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Collection of all amounts due according to the contractual terms means that both the interest and principal payments of a loan will be collected as scheduled in the loan agreement. An impairment allowance is recognized if the fair value of the loan is less than the recorded investment in the loan. The impairment is recognized through the allowance. Loans that are impaired are recorded at the present value of expect ed future cash flows discounted at the loan’s effective interest rate, or if the loan is collateral dependent, the impairment measurement is based on the fair value of the collateral, less estimated disposal costs. The level of allowance maintained is be lieved by management to be adequate to absorb probable losses inherent in the portfolio at the balance sheet date. The allowance is increased by provisions charged to expense and decreased by charge-offs, net of recoveries of amounts previously charged-off . In assessing the adequacy of the allowance, the Company also considers the results of its ongoing internal and independent loan review processes. The Company’s loan review process assists in determining whether there are loans in the portfolio whose cr edit quality has weakened over time and evaluating the risk characteristics of the entire loan portfolio. The Company’s loan review process includes the judgment of management, the input from our independent loan reviewers, and reviews conducted by bank re gulatory agencies as part of their examination process. The Company incorporates loan review results in the determination of whether or not it is probable that it will be able to collect all amounts due according to the contractual terms of a loan. As pa rt of the Company’s quarterly assessment of the allowance, management divides the loan portfolio into five segments: commercial and industrial, construction and land development, commercial real estate, residential real estate, and consumer installment. Th e Company analyzes each segment and estimates an allowance allocation for each loan segment. The allocation of the allowance for loan losses begins with a process of estimating the probable losses inherent for each loan segment. The estimates for these l oans are established by category and based on the Company’s internal system of credit risk ratings and historical loss data. The estimated loan loss allocation rate for the Company’s internal system of credit risk grades is based on its experience with si milarly graded loans. For loan segments where the Company believes it does not have sufficient historical loss data, the Company may make adjustments based, in part, on loss rates of peer bank groups. At September 30, 2017 and December 31, 2016 , and for the periods then ended, the Company adjusted its historical loss rates for the commercial real estate portfolio segment based, in part, on loss rates of peer bank groups. The estimated loan loss allocation for all five loan portfolio segments is then adjusted for management’s estimate of probable losses for several “qualitative and environmental” factors. The allocation for qualitative and environmental factors is particularly subjective and does not lend itself to exact mathematical calculation. This amount represents estimated probable inherent credit losses which exist, but have not yet been identified, as of the balance sheet date, and are based upon quarterly trend assessments in delinquent and nonaccrual loans, credit concentration changes, prevai ling economic conditions, changes in lending personnel experience, changes in lending policies or procedures, and other factors. These qualitative and environmental factors are considered for each of the five loan segments and the allowance allocation, as determined by the processes noted above, is increased or decreased based on the incremental assessment of these factors. The Company regularly re-evaluates its practices in determining the allowance for loan losses. Beginning with the quarter ended Decem ber 31, 2016, the Company implemented cer tain refinements to its allowance for loan losses methodology in order to better capture the effects of the most recent economic cycle on the Company’s loan loss experience. First, the Company increased its look-bac k period for calculating average losses for all loan segments to 31 quarters. Prior to December 31, 2016, the Company calculated average losses for all loan segments using a rolling 20 quarter look-back period. For the quarter ended September 30, 2017 , the Company increased its look-back period to 3 4 quarters to continue to include the losses incurred by the Company beginning with the first quarter of 2009. The Company will likely continue to increase its look-back period to incorporate the effects of at least one economic downturn in its loss history. The Company believes the extension of its look-back period is appropriate due to the risks inherent in the loan portfolio. Absent this extension, the early cycle periods in which the Company experienced significant losses would be excluded from the determination of the allowance for loan losses and its balance would decrease. Second, the Company increased the range of basis point adjustments allowed for qualitative and environmental factors to approximate ly 200 basis points, an increase of 65 basis points, or 48%, compared to the 135 basis point range used prior to December 31, 2016. After performing sensitivity testing of its calculation of the allowance for loan losses, the Company determined that it sho uld increase the range of basis points allowed for qualitative and environmental factors in order to provide sufficient latitude in determining estimated probable credit losses during periods of economic stress. Third, the Company reduced the percentage al location for qualitative and environmental factors on a weighted average basis to 21% of total basis points allocable at December 31, 2016, compared to 25% of total basis points allocable at September 30, 2016. The Company believes a decrease in the percen tage allocation of qualitative environmental factors on a weighted average basis was appropriate due to the extension of its look-back period described above. If the Company did not make the changes described above, the Company’s calculated allowance for l oan loss allocation would have decreased by approximately $0.9 million, or 0.21% of total loans, at December 31, 2016. Other than the changes discussed above, the Company has not made any material changes to its methodology that would impact the calculatio n of the allowance for loan losses or provision for loan losses for the periods included in the accompanying consolidated balance sheets and statements of earnings. The following table details the changes in the allowance for loan losses by portfolio seg ment for the respective periods .

Credit Quality Indicators The credit quality of the loan portfolio is summarized no less frequently than quarterly using categories similar to the standard asset classification system used by the federal banking agencies. The following table presents credit quality indicators for the loan portfolio segments and classes. These categories are utilized to develop the associated allowance for loan losses using historical losses adjusted for qualitative and environmental factors and are defined as follows: Pass – loans which are well protected by the current net worth and paying capacity of the obligor (or guarantors, if any) or by the fair value, less cost to acquire and sell, of any underlying collateral. Special Mention – loans with potential weakness that may, if not reversed or c orrected, weaken the credit or inadequately protect the Company’s position at some future date. These loans are not adversely classified and do not expose an institution to sufficient risk to warrant an adverse classification. Substandard Accruing – loans that exhibit a well-defined weakness which presently jeopardizes debt repayment, even though they are currently performing. These loans are characterized by the distinct possibility that the Company may incur a loss in the future if these weaknesses are n ot corrected . Nonaccrual – includes loans where management has determined that full payment of principal and i nterest is not expected.

In the normal course of business, management may grant concessions to borrowers that are experiencing financial difficulty. A concession may include, but is not limited to, delays in required payments of principal and interest for a specified period, reduction of the stated interest rate of the loan, reduction of accrued interest, extension of the maturity date, or reduction of the face amount or maturity a mount of the debt. A concession has been granted when, as a result of the restructuring, the Bank does not expect to collect, where due, all amounts owed, including interest at the original stated rate. A concession may have also been granted if the debtor is not abl e to access funds elsewhere at a market rate for debt with similar risk characteristics as the restructured debt. In making the determination of whether a loan modification is a TDR, the Company considers the individual facts and circumstances surrounding each modification. As part of the credit approval process, the restructured loans are evaluated for adequate collateral protection in determining the appropriate accrual status at the time of restructure. Similar to other impaired loans, TDRs are meas ured for impairment based on the present value of expected payments using the loan’s original effective interest rate as the discount rate, or the fair value of the collateral, less selling costs if the loan is collateral dependent. If the recorded investm ent in the loan exceeds the measure of fair value, impairment is recognized by establishing a valuation allowance as part of the allowance for loan losses or a charge-off to the allowance for loan losses. In periods subsequent to the modification, all TDR s are individually evaluated for possible impairment. The following is a summary of accruing and nonaccrual TDRs, which are included in the impaired loan totals, and the related allowance for loan losses, by portfolio segment and class as of September 30, 2017 and December 31, 2016 .

During the three and nine months ended September 30, 2017 and 2016 , there were no loans modified in a TDR within the previous 12 months for which there was a payment default (defined as 90 days or more past due).

Mortgage Servicing [Abstract]
Transfers and Servicing of Financial Assets [Text Block]	NOTE 6 : MORTGAGE SERVICING RIGHTS, NET Mortgage servicing rights (“MSRs”) are recognized based on the fair value of the servicing rights on the date the corresponding mortgage loans are sold. An estimate of the fair value of the Company’s MSRs is determined using assumptions that market participants would use in estimating future net servicing income, including estimates of prepayment speeds, discount rates, default rates, costs to service, escrow account earnings, contractual servicing fee inco me, ancillary income, and late fees. Subsequent to the date of transfer, the Company has elected to measure its MSRs under the amortization method. Under the amortization method, MSRs are amortized in proportion to, and over the period of, estimated net servicing income. The Company has recorded MSRs related to loans sold without recourse to Fannie Mae. The Company generally sells conforming, fixed-rate, closed-end, residential mortgages to Fannie Mae. MSRs are included in other assets on the accompa nying consolidated balance sheets. The Company evaluates MSRs for impairment on a quarterly basis. Impairment is determined by stratifying MSRs into groupings based on predominant risk characteristics, such as interest rate and loan type. If, by individ ual stratum, the carrying amount of the MSRs exceeds fair value, a valuation allowance is established. The valuation allowance is adjusted as the fair value changes.

Derivative instruments and hedging activities disclosure abstract
Derivative Instruments And Hedging Activities Disclosure Text Block	NOTE 7 : DERIVATIVE INSTRUMENTS Financial derivatives are reported at fair value in other assets or other liabilities on the accompanying consolidated balance sheets. The accounting for changes in the fair value of a derivative depends on whether it has been designated and qualifies as part of a hedging relationship. For derivatives not designated as part of a hedging relationship, the gain or loss is recognized in current earnings within other noninterest income on the accompanying consolidated stat ements of earnings. From time to time, the Company may enter into interest rate swaps (“swaps”) to facilitate customer transactions and meet their financing needs. Upon entering into these swaps, the Company enters into offsetting positions in order to min imize the risk to the Company. These swaps qualify as derivatives, but are not designated as hedging instruments. Interest rate swap agreements involve the risk of dealing with counterparties and their ability to meet contractual terms. When the fair va lue of a derivative instrument is positive, this generally indicates that the counterparty or customer owes the Company, and results in credit risk to the Company. When the fair value of a derivative instrument is negative, the Company owes the customer or counterparty and therefore, has no credit risk. A summary of the Company’s interest rate swap agreements at September 30, 2017 and December 31, 2016 is presented below. Other Other Assets Liabilities Estimated Estimated (Dollars in thousands) Notional Fair Value Fair Value September 30, 2017: Pay fixed / receive variable $ 3,704 — 96 Pay variable / receive fixed 3,704 96 — Total interest rate swap agreements $ 7,408 96 96 December 31, 2016: Pay fixed / receive variable $ 3,967 — 241 Pay variable / receive fixed 3,967 241 — Total interest rate swap agreements $ 7,934 241 241

Fair Value Disclosures [Abstract]
Fair Value Disclosures Text Block	NOTE 8 : FAIR VALUE Fair Value Hierarchy “Fair value” is defined by ASC 820, Fair Value Measurements and Disclosures , as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for an asset or liability at the measurement date. GAAP establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: Level 1—inputs to the valuation methodology are quoted prices, unadjusted, for identical assets or liabilities in active markets. Level 2—inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs that are observable fo r the asset or liability, either directly or indirectly. Level 3—inputs to the valuation methodology are unobservable and reflect the Company’s own assumptions about the inputs market participants would use in pricing the asset or liability. Level ch anges in fair value measurements Transfers between levels of the fair value hierarchy are generally recognized at the end of each reporting period. The Company monitors the valuation techniques utilized for each category of financial assets and liabiliti es to ascertain when transfers between levels have been affected. The nature of the Company’s financial assets and liabilities generally is such that transfers in and out of any level are expected to be infrequent. For the nine months ended September 30, 2017 , ther e were no transfers between levels and no changes in valuation techniques for the Company’s financial assets and liabilities. Assets and liabilities measured at fair value on a recurring basis Securities available-for-sale Fair values of securities avai lable for sale were primarily measured using Level 2 inputs. For these securities, the Company obtains pricing from third party pricing services. These third party pricing services consider observable data that may include broker/dealer quotes, market sp reads, cash flows, benchmark yields, reported trades for similar securities, market consensus prepayment speeds, credit information, and the securities’ terms and conditions. On a quarterly basis, management reviews the pricing received from the third par ty pricing services for reasonableness given current market conditions. As part of its review, management may obtain non-binding third party broker quotes to validate the fair value measurements. In addition, management will periodically submit pricing p rovided by the third party pricing services to another independent valuation firm on a sample basis. This independent valuation firm will compare the price provided by the third party pricing service with its own price and will review the significant assu mptions and valuation methodologies used with management. Interest rate swap agreements The carrying amount of interest rate swap agreements was included in other assets and accrued expenses and other liabilities on the accompanying consolidated b alance sheets. The fair value measurements for our interest rate swap agreements were based on information obtained from a third party bank. This information is periodically tested by the Company and validated against other third party valuations. If ne eded, other third party market participants may be utilized to corroborate the fair value measurements for our interest rate swap agreements. The Company classified these derivative assets and liabilities within Level 2 of the valuation hierarchy. These s waps qualify as derivatives, but are not designated as hedging instruments. The following table presents the balances of the assets and liabilities measured at fair value on a recurring basis as of September 30, 2017 and December 31, 2016 , respectively, by caption, on the accompanying c onsolidated balance sheets by ASC 820 valuation hierarchy (as described above).

Assets and liabilities measured at fair value on a nonrecurring basis Loans held for sale Loans held for sale are c arried at the lower of cost or fair value. F air value s of loans held for sale are determined using quoted market secondary market prices for similar loans. L oans held for sale are classified within Level 2 of the fair value hierarchy. Impaired Loans Loans considered impaired under ASC 310-10-35, Receivables , are loans for which, based on current information and events, it is probable tha t the Company will be unable to collect all principal and interest payments due in accordance with the contractual terms of the loan agreement. Impaired loans can be measured based on the present value of expected payments using the loan’s original effecti ve rate as the discount rate, the loan’s observable market price, or the fair value of the collateral less selling costs if the loan is collateral dependent. The fair value of impaired loans were prim arily measured based on the value of the collateral securing these loans. Impaired loans are classified within Level 3 of the fair value hierarchy. Collateral may be real estate and/or business assets including equipment, inventory, and/or accounts receivable. The Company determines the value of the collate ral based on independent appraisals performed by qualified licensed appraisers. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Appraised values are discounted for costs to sell and may be discounted further based on management’s historical knowledge, changes in market conditions from the date of the most recent appraisal, and/or management’s expertise and knowledge of the customer and the customer’s business. Such d iscounts by management are subjective and are typically significant unobservable 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 sam e factors discussed above. Other real estate owned Other real estate owned, consisting of properties obtained through foreclosure or in satisfaction of loans, are initially recorded at the lower of the loan’s carrying amount or the fair value of collateral less costs to sell upon transfer of the loans to other real estate. Subsequently, other real estate is carried at the lower of carrying value or fair value less costs to sell. Fair values are generally based on third party appraisals of the property and are classifi ed within Level 3 of the fair value hierarchy. The appraisals are sometimes further discounted based on management’s historical knowledge, and/or changes in market conditions from the date of the most recent appraisal, and/or management’s expertise and kno wledge of the customer and the customer’s business. Such discounts are typically significant unobservable inputs for determining fair value. In cases where the carrying amount exceeds the fair value, less costs to sell, a loss is recognized in noninterest expense. Mortgage servicing rights, net M ortgage servicing rights, net, included in other assets on the accompanying consolidated balance sheets, are carried at the lower of cost or estimated fair value. MSRs do not trade in an active market with readi ly observable prices. To determine the fair value of MSRs, the Company engages an independent third party. The independent third party’s valuation model calculates the present value of estimated future net servicing income using assumptions that market p articipants would use in estimating future net servicing income, including estimates of prepayment speeds, discount rate s , default rates, cost to service, escrow account earnings, contractual servicing fee income, ancillary income, and late fees. Periodic ally, the Company will review broker surveys and other market research to validate significant assumptions used in the model. The significant unobservable inputs include prepayment speeds or the constant prepayment rate (“CPR”) and the weighted average di scount rate. Because the valuation of MSRs requires the use of significant unobservable inputs, all of the Company’s MSRs are classified within Level 3 of the valuation hierarchy. The following table presents the balances of the assets and liabilities me asured at fair value on a nonrecurring basis as of September 30, 2017 and December 31, 2016 , respectively, by caption, on the accompanying consolidated b ala nce s heets and by FASB ASC 820 valuation hierarchy (as described above): Quoted Prices in Active Markets Other Significant for Observable Unobservable Carrying Identical Assets Inputs Inputs (Dollars in thousands) Amount (Level 1) (Level 2) (Level 3) September 30, 2017: Loans held for sale $ 924 — 924 — Loans, net (1) 2,664 — — 2,664 Other real estate owned 103 — — 103 Other assets (2) 1,703 — — 1,703 Total assets at fair value $ 5,394 — 924 4,470 December 31, 2016: Loans held for sale $ 1,497 — 1,497 — Loans, net (1) 2,099 — — 2,099 Other real estate owned 152 — — 152 Other assets (2) 1,952 — — 1,952 Total assets at fair value $ 5,700 — 1,497 4,203 (1) Loans considered impaired under ASC 310-10-35, Receivables .

Quantitative Disclosures for Level 3 Fair Value Measurements At September 30, 2017 , the Company had no Level 3 assets measured at fair value on a recurring basis. For Level 3 assets measured at fair value on a non-recurring basis at September 30, 2017 , the significant unobservable inputs used in the fair value measurements are presented below. Weighted Carrying Average (Dollars in thousands) Amount Valuation Technique Significant Unobservable Input of Input Nonrecurring: Impaired loans $ 2,664 Appraisal Appraisal discounts (%) 16.9 % Other real estate owned 103 Appraisal Appraisal discounts (%) 18.9 % Mortgage servicing rights, net 1,703 Discounted cash flow Prepayment speed or CPR (%) 11.0 % Discount rate (%) 10.0 % Fair Value of Financial Instruments ASC 825, Financial Instruments , requires disclosure of fair value information about financial instruments, whether or not recognized on the face of the balance sheet, for which it is practicable to estimate that value. The assumptions used in the estimation of the fair value of the Company’s financial instruments are explained below. Where quoted market prices are not available, fair values are based on estimates using discounted cash flow analyses . Discounted cash flow s can be significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. The following fair value estimates cannot be substantiated by comparison to independent markets and should not be considered representa tive of the liquidation value of the Company’s financial instruments, but rather are a good- faith estimate of the fair value of financial instru ments held by the Company. ASC 825 excludes certain financial instruments and all nonfinancial instruments from its disclosure requirements. The following methods and assumptions were used by the Company in estimating the fair value of its financial instruments: Loans, net Fair value s for loans were calculated using discounted cash flows. The discount rates r eflected current rates at which similar loans would be made for the same remaining maturities. This method of estimating fair value does not incorporate the exit-price concept of fair value prescribed by ASC 820 and generally produces a higher value than a n exit-price approach. E xpected future cash flows were projected based on contractual cash flows, adjusted for estimated prepayments. ASU 2016-01 described under “Current Accounting Developments ” requires public company use of exit prices when measuring the f air value of financial instruments for disclosure purposes for fiscal years beginning after December 31, 2017. The effects of ASU 2016-01 on the Company’s consolidated financial statements are being evaluated. Loans held for sale Fair values of loans held for sale are determined using quoted secondary market prices for similar loans. Time Deposits F air values for time deposits we re estimated us ing discounted cash flows . The discount rates were based on rates currently offered f or deposits with similar remaining maturities. Long-term debt The fair value of the Company’s fixed rate long-term debt is estimated using discounted cash flows based on estimated current market rates for similar types of borrowing arrangements. The c arrying amount of the Company’s variable rate long-term debt approximates its fair value. The carrying value , related estimated fair value , and placement in the fair value hierarchy of the Company’s financial instruments at September 30, 2017 and December 31, 2016 are presented below. This table excludes financial instruments for which the carrying amount approximates fair value. Financial assets for which fair value approximates carrying value included cash and cash equivalents. Financial liabilities for which fair value approximates carrying value included noninterest-bearing demand deposits , interest-bearing demand deposits , and savings deposits due to these products having no stated maturity. In addition, financial liabilities for which fair value approximates carrying value included overnight borrowings such as federal funds purchased and securities sold under agreements to repurchase.
