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 individuals and commercial customers in Lee County, Alabama and surrounding areas 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, 2024. The unaudited consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. 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 the determination of allowance for credit losses on loans and investment securities, the fair value of financial instruments, and the valuation of deferred tax assets and other real estate owned (“OREO”). 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, 2025. 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. Reclassifications Certain amounts reported in prior periods have been reclassified to conform to the current-period presentation. These reclassifications had no effect on the Company’s previously reported net earnings or total stockholders’ equity. Accounting Developments I n the first nine months of 2025, the Company did not adopt any new accounting guidance.
