Notes to Financial Statements |
Organization, Consolidation, Basis of Presentation, Business Description and Accounting Policies [Text Block] | Note 1. General The accompanying unaudited consolidated financial statements of First National Corporation (the Company) and its subsidiary, First Bank (the Bank), have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and in accordance with guidance provided by the SEC. Accordingly, they do not include all of the information and footnotes required by GAAP for annual year-end financial statements. All significant intercompany balances and transactions have been eliminated. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments and reclassifications of a normal and recurring nature considered necessary to present fairly the financial positions at September 30, 2022 and December 31, 2021, the statements of income and comprehensive (loss) income for the three and nine months ended September 30, 2022 and 2021, the cash flows for the nine months ended September 30, 2022 and 2021, and the changes in shareholders’ equity for the three and nine months ended September 30, 2022 and 2021. The statements should be read in conjunction with the consolidated financial statements and related notes included in the Annual Report on Form 10-K for the year ended December 31, 2021. Operating results for the three and nine months ended September 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. Recent Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (ASU 2016-13). The amendments in this ASU, among other things, require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The FASB has issued multiple updates to ASU 2016-13 as codified in Topic 326, including ASU’s 2019-04, 2019-05, 2019-10, 2019-11, 2020-02, and 2020-03. These ASU’s have provided for various minor technical corrections and improvements to the codification as well as other transition matters. Smaller reporting companies who file with the U.S. Securities and Exchange Commission (SEC), such as the Company, and all other entities who do not file with the SEC are required to apply the guidance for fiscal years, and interim periods within those years, beginning after December 15, 2022. The Company is currently assessing the impact that ASU 2016-13 will have on its consolidated financial statements. The Company has formed a committee to address the compliance requirements of this ASU, which has analyzed gathered data, defined loan pools and segments, and selected methods for applying the concepts included in this ASU. The Company is in the process of testing selected models, building policy and process documentation, modeling the impact of the ASU on the capital and strategic plans, performing model validation, and finalizing policies and procedures. This guidance may result in material changes in the Company's accounting for credit losses of financial instruments. In March 2022, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2022-01, “Derivatives and Hedging (Topic 815), Fair Value Hedging—Portfolio Layer Method.” ASU 2022-01 clarifies the guidance in ASC 815 on fair value hedge accounting of interest rate risk for portfolios of financial assets and is intended to better align hedge accounting with an organization’s risk management strategies. In 2017, FASB issued ASU 2017-12 to better align the economic results of risk management activities with hedge accounting. One of the major provisions of that standard was the addition of the last-of-layer hedging method. For a closed portfolio of fixed-rate prepayable financial assets or one or more beneficial interests secured by a portfolio of prepayable financial instruments, such as mortgages or mortgage-backed securities, the last-of-layer method allows an entity to hedge its exposure to fair value changes due to changes in interest rates for a portion of the portfolio that is not expected to be affected by prepayments, defaults, and other events affecting the timing and amount of cash flows. ASU 2022-01 renames that method the portfolio layer method. For public business entities, ASU 2022-01 is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. The Company does not expect the adoption of ASU 2022-01 to have a material impact on its consolidated financial statements. In March 2022, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2022-02, “Financial Instruments-Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures.” ASU 2022-02 addresses areas identified by the FASB as part of its post-implementation review of the credit losses standard (ASU 2016-13) that introduced the CECL model. The amendments eliminate the accounting guidance for troubled debt restructurings by creditors that have adopted the CECL model and enhance the disclosure requirements for loan refinancings and restructurings made with borrowers experiencing financial difficulty. In addition, the amendments require a public business entity to disclose current-period gross write-offs for financing receivables and net investment in leases by year of origination in the vintage disclosures. For entities that have adopted ASU 2016-13, ASU 2022-02 is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. For entities that have not yet adopted ASU 2016-13, the effective dates for ASU 2022-02 are the same as the effective dates in ASU 2016-13. Early adoption is permitted if an entity has adopted ASU 2016-13. The Company is currently assessing the impact that ASU 2022-02 will have on its consolidated financial statements. Effective November 25, 2019, the SEC adopted Staff Accounting Bulletin (SAB) 119. SAB 119 updated portions of SEC interpretative guidance to align with FASB ASC 326, “Financial Instruments – Credit Losses.” It covers topics including (1) measuring current expected credit losses; (2) development, governance, and documentation of a systematic methodology; (3) documenting the results of a systematic methodology; and (4) validating a systematic methodology. In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (ASU 2020-04). These amendments provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The ASU provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. It is intended to help stakeholders during the global market-wide reference rate transition period. The guidance is effective for all entities as of March 12, 2020 through December 31, 2022. Subsequently, in January 2021, the FASB issued ASU No. 2021-01 “Reference Rate Reform (Topic 848): Scope” (ASU 2021-01). This ASU clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The ASU also amends the expedients and exceptions in Topic 848 to capture the incremental consequences of the scope clarification and to tailor the existing guidance to derivative instruments affected by the discounting transition. An entity may elect to apply ASU 2021-01 on contract modifications that change the interest rate used for margining, discounting, or contract price alignment retrospectively as of any date from the beginning of the interim period that includes March 12, 2020, or prospectively to new modifications from any date within the interim period that includes or is subsequent to January 7, 2021, up to the date that financial statements are available to be issued. An entity may elect to apply ASU 2021-01 to eligible hedging relationships existing as of the beginning of the interim period that includes March 12, 2020, and to new eligible hedging relationships entered into after the beginning of the interim period that includes March 12, 2020. The Company has identified loans and other financial instruments that are directly or indirectly influenced by LIBOR. The Company is assessing ASU 2020-04 and its impact on the Company's transition away from LIBOR for its loan and other financial instruments. In June 2022, the FASB issued ASU 2022-03, “Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions.” ASU 2022-03 clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. The ASU is effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2023. Early adoption is permitted. The Company does not expect the adoption of ASU 2022-03 to have a material impact on its consolidated financial statements.
