Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation The accompanying unaudited interim consolidated financial statements include the accounts of BancFirst Corporation, Council Oak Partners, LLC, BancFirst Insurance Services, Inc., Pegasus Bank ("Pegasus"), Worthington Bank ("Worthington") and BancFirst and its subsidiaries ("BancFirst"). The principal operating subsidiaries of BancFirst are BFTower, LLC, BFC-PNC LLC, and BancFirst Agency, Inc. All significant intercompany accounts and transactions have been eliminated. Assets held in a fiduciary or agency capacity are not assets of the Company and, accordingly, are not included in the unaudited interim consolidated financial statements. The accompanying unaudited interim consolidated financial statements and notes are presented in accordance with U.S. GAAP for interim financial information and the instructions for Form 10-Q adopted by the Securities and Exchange Commission (“SEC”). The information contained in the consolidated financial statements and footnotes included in BancFirst Corporation’s Annual Report on Form 10-K for the year ended December 31, 2022, should be referred to in connection with these unaudited interim consolidated financial statements. Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period. The unaudited interim consolidated financial statements contained herein reflect all adjustments, which are, in the opinion of management, necessary to provide a fair statement of the financial position and results of operations of the Company for the interim periods presented. All such adjustments are of a normal and recurring nature.
Reclassifications | Reclassifications Certain loan segments from 2022 have been reclassified to conform to the 2023 presentation. Such reclassifications had no effect on previously reported balance sheets, cash flows, stockholders’ equity or comprehensive income.
Use of Estimates in the Preparation of Financial Statements | Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with accounting principles generally accepted in the United States inherently involves the use of estimates and assumptions that affect the amounts reported in the financial statements and the related disclosures. These estimates relate principally to the determination of the allowance for credit losses, income taxes, the fair value of financial instruments and the valuation of assets and liabilities acquired in a business combination, including identifiable intangible assets. Such estimates and assumptions may change over time and actual amounts realized may differ from those reported.
Recent Accounting Pronouncements | Recent Accounting Pronouncements Standards Adopted During the Current Period: In March 2022, FASB issued ASU No. 2022-02, “Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures.” ASU 2022-02 eliminated the Troubled Debt Restructurings (“TDR”) recognition and measurement guidance and, instead, required that the Company evaluate, based on the accounting for loan modifications, whether the modification represents a new loan or a continuation of an existing loan when a borrower is experiencing financial difficulty. In addition, the update required that the Company disclose current-period charge-offs by year of origination for financing receivables. The current-period charge-off amendment was applied prospectively. The amendments were effective for annual periods beginning after December 15, 2022, including interim periods within those annual periods. The Company adopted ASU 2022-02 on January 1, 2023. ASU No. 2022-02 did not have a significant impact on the Company’s consolidated financial statements. In March 2023, FASB issued ASU No. 2023-02, "Investments - Equity Method and Joint Ventures (Topic 323)." ASU 2023-02 permits the election of accounting for 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. Using the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the income tax credits and other income tax benefits received and recognizes the net amortization and income tax credits and other income tax benefits in the income statement as a component of income tax expense (benefit). The amendments are effective for annual periods beginning after December 15, 2023, including interim periods within those annual periods. Early adoption is permitted for all entities in any interim period. The Company adopted the amendment as of January 1, 2023 using the modified retrospective transition. The Company has investments in New Markets Tax Credits ("NMTC") and Low-Income Housing Tax Credits ("LIHTC") that were affected by ASU 2023-02. Upon adoption of ASU No. 2023-02, the Company recorded $21.8 million in other assets and other liabilities on the consolidated balance sheet for unfunded LIHTC commitments and amortized $977,000 of NMTC investments to income tax expense during the period that would have previously been recorded to other expense. ASU No. 2023-02 did no t have a significant impact on the Company’s consolidated financial statements.
