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. 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, 2017. 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 June 30, 2018. 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. Accounting Developments In the first six months of 2018, the Company adopted new guidance related to the following Accounting Standards Updates (“Updates” or “ASUs”): • ASU 2014-09, Revenue from Contracts with Customers; • ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities; • ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments; and • ASU 2016-18, Restricted Cash Information about these pronouncements is described in more detail below. ASU 2014-09, Revenue from Contracts with Customers (Topic 606), was developed as a joint project with the International Accounting Standards Board to remove inconsistencies in revenue requirements and provide a more robust framework for addressing revenue issues. The ASU’s core principle is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU 2015-14, which deferred the effective date by one year (i.e., interim and annual reporting periods beginning after December 15, 2017). Early adoption is permitted, but not before the original effective date (i.e., interim and annual reporting periods beginning after December 15, 2016). The ASU may be adopted using either a modified retrospective method or a full retrospective method. The Company adopted the ASU during the first quarter of 2018, as required, using a modified retrospective approach. The majority of the Company’s revenue stream is generated from interest income on loans and deposits, which are outside the scope of Topic 606. The Company’s sources of income that fall within the scope of Topic 606 include service charges on deposits, investment services, interchange fees and gains and losses on sales of other real estate, all of which are presented as components of noninterest income. The Company has evaluated the effect of Topic 606 on these fee-based income streams and concluded that adoption of the standard did not materially impact its financial statements. The following is a summary of the implementation considerations for the revenue streams that fall within the scope of Topic 606: Service charges on deposits, investment services, ATM and interchange fees — Fees from these services are either transaction-based, for which the performance obligations are satisfied when the individual transaction is processed, or set periodic service charges, for which the performance obligations are satisfied over the period the service is provided. Transaction-based fees are recognized at the time the transaction is processed, and periodic service charges are recognized over the service period. The adoption of Topic 606 had no impact on the Company’s revenue recognition practice for these services. Gains on sales of other real estate — ASU 2014-09 creates Topic 610-20, under which a gain on sale should be recognized when a contract for sale exists and control of the asset has been transferred to the buyer. Topic 606 lists several criteria required to conclude that a contract for sale exists, including a determination that the institution will collect substantially all of the consideration to which it is entitled. This presents a key difference between the prior and new guidance related to the recognition of the gain when the institution finances the sale of the property. Rather than basing recognition on the amount of the buyer's initial investment, which was the primary consideration under prior guidance, the analysis is now based on various factors including not only the loan to value, but also the credit quality of the borrower, the structure of the loan, and any other factors that may affect collectability. While these differences may affect the decision to recognize or defer gains on sales of other real estate in circumstances where the Company has financed the sale, the effects would not be material to its consolidated financial statements. ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, enhances the reporting model for financial instruments to provide users of financial statements with more decision-useful information. The ASU addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Some of the amendments include the following: (1) Require equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; (2) Simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; (3) Require public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (4) Require 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; among others. For public business entities, the amendments of this ASU are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of this ASU on January 1, 2018 did not have a material impact on the Company’s Consolidated Financial Statements. In accordance with (3) above, the Company measured the fair value of its loan portfolio as of June 30, 2018 using an exit price notion and will continue to do so going forward (see Note 7). ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, provides guidance on eight specific cash flow issues where current GAAP is either unclear or does not include specific guidance on classification in the statement of cash flows. The new guidance is effective for annual and interim reporting periods in fiscal years beginning after December 15, 2017. The Company adopted ASU No. 2016-15 on January 1, 2018. ASU No. 2016-15 did not have a material impact on the Company’s Consolidated Financial Statements. ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, amends guidance on how the statement of cash flows presents the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Under the new guidance, amounts generally described as restricted cash and restricted cash equivalents are included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this Update do not provide a definition of restricted cash or restricted cash equivalents. The new guidance is effective for public business entities for annual and interim reporting periods in fiscal years beginning after December 15, 2017. The Company adopted ASU No. 2016-18 on January 1, 2018. ASU No. 2016-18 did not have a material impact on the Company’s Consolidated Financial Statements.

Accounting Developments

In the first six months of 2018, the Company adopted new guidance related to the following Accounting Standards Updates (“Updates” or “ASUs”):

•

ASU 2014-09, Revenue from Contracts with Customers;

•

ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities;

•

ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments; and

•

ASU 2016-18, Restricted Cash

Information about these pronouncements is described in more detail below.

The Company has evaluated the effect of Topic 606 on these fee-based income streams and concluded that adoption of the standard did not materially impact its financial statements.

Transaction-based fees are recognized at the time the transaction is processed, and periodic service charges are recognized over the service period. The adoption of Topic 606 had no impact on the Company’s revenue recognition practice for these services.
