Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	Organization and Basis of Presentation The consolidated financial statements include the accounts of First Bancorp (the “Company”) and its wholly owned subsidiary First Bank (the “Bank”). The Bank has three wholly owned subsidiaries that are fully consolidated, SBA Complete, Inc. (“SBA Complete”), Magnolia Financial, Inc. ("Magnolia Financial"), and First Troy SPE, LLC. All significant intercompany accounts and transactions have been eliminated. The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all information and notes necessary for complete financial statements in accordance with GAAP. In the opinion of the Company, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly the consolidated financial position of the Company as of September 30, 2023, the consolidated results of operations for the three and nine months ended September 30, 2023 and 2022, and the consolidated cash flows for the nine months ended September 30, 2023 and 2022. Any such adjustments were of a normal, recurring nature. These interim financial statements should be read in conjunction with the Company's audited consolidated financial statements and notes in the Annual Report on Form 10-K for the year ended December 31, 2022. Operating results for interim period are not necessarily indicative of the results that may be expected for the full year. Reference is made to Note 1 of the 2022 Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) for a discussion of accounting policies and other relevant information with respect to the financial statements. Certain reclassifications have been made to the September 30, 2022 and December 31, 2022 consolidated financial statements to be comparable to September 30, 2023. These reclassifications had no effect on net income. The Company has evaluated all subsequent events through the date the financial statements were issued. Accounting Standards Adopted in 2023 ASU 2022-02, "Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures." The amendments contained in this Accounting Standards Update ("ASU") eliminate the accounting guidance for troubled debt restructurings ("TDR") by creditors, while enhancing disclosure requirements for certain loan refinancing and restructurings by creditors when a borrower is experiencing financial difficulty. This ASU also requires entities to disclose current period gross write-offs by year of origination for financing receivables. The Company adopted ASU 2022-02 effective January 1, 2023 using a modified retrospective transition approach for the amendments related to the recognition and measurement of TDRs. The impact of the adoption resulted in an immaterial change to the allowance for credit losses ("ACL"), thus no adjustment to retained earnings was recorded. Disclosures have been updated to reflect information on loan modifications given to borrowers experiencing financial difficulty as presented in Note 4. TDR disclosures are presented for comparative periods only and are not required to be updated in current periods. Additionally, the current year vintage disclosure included in Note 4 has been updated to reflect gross charge-offs by year of origination for the nine months ended September 30, 2023. ASU 2022-03, "Fair Value Measurements (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions." This ASU 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 Company adopted ASU 2022-03 January 1, 2023 with no material impact on its financial statements. ASU 2022-06, "Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848." In 2020, the Financial Accounting Standards Board ("FASB") issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provided optional guidance to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform. The objective of the guidance in Topic 848 was to provide relief during the temporary transition period and the FASB included a sunset provision based on expectations of when the London Interbank Offered Rate ("LIBOR") would cease being published. The United Kingdom Financial Conduct Authority has extended the intended LIBOR cessation date from December 31, 2021 to June 30, 2023. As such, ASU 2022-06 deferred the sunset date previously set to December 31, 2024, after which entities will no longer be permitted to apply the relief in Topic 848; moreover, it applies to all entities, subject to meeting certain criteria, that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. ASU 2022-06 was adopted upon issuance. The Company will continue to elect various optional expedients for contract modifications affected by rate reference reform through the effective date of this guidance with no material effect on its financial statements. Accounting Standards Pending Adoption ASU 2023-02, “Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method” permits reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. This update is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. The adoption of ASU 2023-02 is not expected to have a significant impact on the Company's consolidated financial statements. Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies are not expected to have a material impact on the Company’s financial position, results of operations or cash flows.
