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.

Basis 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 financial 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 fair 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 operations 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, 2015.

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 unaudited 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 to 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. Actual 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 losses, 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 subsequent to September 30, 2016. 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 except as reported in Note 9, Subsequent Events.

Accounting Developments

In the first quarter of 2016, the Company adopted new guidance related to the following Accounting Standards Updates (“Updates” or “ASUs”):

Table of Contents

Information about these pronouncements is described in more detail below.

ASU 2015-02, Amendments to the Consolidation Analysis, affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. Specifically, the amendments: (1) Modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities (“VIEs”) or voting interest entities; (2) Eliminate the presumption that a general partner should consolidate a limited partnership; (3) Affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships; and (4) Provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. Adoption of this ASU did not have a material impact on the Company’s consolidated financial statements.

ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, requires that debt issuance costs related to a recognized debt liability be presented on the balance sheet as a direct deduction from the debt liability, rather than as an asset. Adoption of this ASU did not have a material impact on the Company’s consolidated financial statements.

ASU 2015-05, Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement , provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The new guidance does not change the accounting for a customer’s accounting for service contracts. Adoption of this ASU did not have a material impact on the Company’s consolidated financial statements.

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, 2016 and 2015, 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.

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, 2016, the Company did not have any consolidated VIEs to disclose but did have one nonconsolidated VIE, discussed below.

Trust Preferred Securities

The Company owns the common stock of a subsidiary business trust, Auburn National Bancorporation Capital Trust I, which issued mandatorily redeemable preferred capital securities (“trust preferred securities”) in the aggregate of approximately $7.0 million at the time of issuance. This 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 acquired by the trust using the proceeds from the issuance of the trust preferred securities and common stock. The junior subordinated debentures of approximately $7.2 million are included in long-term debt and the Company’s equity interest of $0.2 million in the business trust is included in other assets. Interest expense on the junior subordinated debentures 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, 2016.

At September 30, 2016 and December 31, 2015, respectively, all securities within the scope of Accounting Standards Codification (“ASC”) 320, Investments – Debt and Equity Securities, were classified as available-for-sale. The fair value and amortized cost for securities available-for-sale by contractual maturity at September 30, 2016 and December 31, 2015, respectively, are presented below.

Securities with aggregate fair values of $143.6 million and $133.3 million at September 30, 2016 and December 31, 2015, 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, 2016 and December 31, 2015, respectively. Cost-method investments primarily include non-marketable equity investments, such as FHLB of Atlanta stock and Federal Reserve Bank (“FRB”) stock.

Gross Unrealized Losses and Fair Value

The fair values and gross unrealized losses on securities at September 30, 2016 and December 31, 2015, 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.

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 securities’ 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 determining whether a loss is temporary, the Company considers all relevant information including:

Agency obligations

The unrealized losses associated with agency obligations 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 did not have any credit losses given the explicit government guarantee or other government support.

11

Table of Contents

Agency RMBS

The unrealized losses associated with agency 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 did 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 associated 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 insurers. As a result, the Company expects to recover the entire amortized cost basis of these securities.

Cost-method investments

At September 30, 2016, cost-method investments with an aggregate cost of $1.4 million were not evaluated for impairment because the Company did not identify 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 investment 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, 2016 and December 31, 2015, 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, 2016 and 2015, respectively.

Realized Gains and Losses

The following table presents the gross realized gains and losses on sales of securities.

Table of Contents

Loans secured by real estate were approximately 86.0% of the Company’s total loan portfolio at September 30, 2016. At September 30, 2016, 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 portfolio 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 industrial (“C&I”) — includes loans to finance business operations, equipment purchases, or other needs for small and medium-sized commercial customers. Also included 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 credit 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, the primary source of repayment is dependent upon the sale or refinance of the real estate collateral.

Table of Contents

Commercial real estate ( “ CRE ” ) — includes loans disaggregated into three classes: (1) owner occupied, (2) multifamily and (3) other.

Residential real estate (“RRE”) — includes loans disaggregated into two classes: (1) consumer mortgage and (2) investment property.

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 accordance 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.

Table of Contents

The following is a summary of current, accruing past due, and nonaccrual loans by portfolio segment and class as of September 30, 2016 and December 31, 2015.

Allowance for Loan Losses

The Company assesses the adequacy of its allowance for loan losses prior to the end of each calendar quarter. 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 portfolio, 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 cash 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-off 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.

Table of Contents

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 expected 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 believed 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 credit 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 that may have been conducted by bank regulatory 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 part 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. The 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 loans are established by category and based on the Company’s internal system of credit risk ratings and historical loss data. The Company calculates average losses for all loan segments using a rolling 20 quarter historical period. The estimated loan loss allocation rate for the Company’s internal system of credit risk grades is based on its experience with similarly 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, 2016 and December 31, 2015, 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, prevailing economic conditions, changes in lending personnel experience, changes in lending policies or procedures, and other influencing 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.
