Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	NOTE 1. SIGNIFICANT ACCOUNTING POLICIES Nature of Operations First Busey Corporation, a Nevada corporation organized in 1980, is a $12.0 billion financial holding company headquartered in Champaign, Illinois. Busey’s common stock is traded on The Nasdaq Global Select Market under the symbol “BUSE.” Busey operates and reports its business in three segments: Banking, Wealth Management, and FirsTech. •The Banking operating segment provides a full range of banking services to individual and corporate customers through its banking center network in Illinois; the St. Louis, Missouri metropolitan area; southwest Florida; and Indianapolis, Indiana. •The Wealth Management operating segment provides a full range of asset management, investment, brokerage, fiduciary, philanthropic advisory, tax preparation, and farm management services to individuals, businesses, and foundations. •The FirsTech operating segment provides comprehensive and innovative payment technology solutions including online, mobile, and voice-recognition bill payments; money management and credit card networks; direct debit services; lockbox remittance processing for payments made by mail; and walk-in payments. FirsTech also provides additional tools to help clients with billing, reconciliation, bill reminders, and treasury services. For additional information about First Busey's operating segments, see “Note 15. Operating Segments and Related Information.” Basis of Financial Statement Presentation These unaudited consolidated financial statements and related notes should be read in conjunction with the audited consolidated financial statements included in Busey's 2023 Annual Report. These interim unaudited consolidated financial statements serve to update our 2023 Annual Report and may not include all information and notes necessary to constitute a complete set of financial statements. We prepared these unaudited consolidated financial statements in conformity with GAAP. We have eliminated intercompany accounts and transactions. We have also reclassified certain prior year amounts to conform to the current period presentation. These reclassifications did not have a material impact on our consolidated financial condition or results of operations. In our opinion, the unaudited consolidated financial statements reflect all normal, recurring adjustments needed to present fairly our results for the interim periods. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period. Use of Estimates In preparing the accompanying unaudited consolidated financial statements in conformity with GAAP, Busey’s management is required to make estimates and assumptions that affect the amounts reported in the financial statements and the disclosures provided. Actual results could differ from those estimates. Material estimates which are particularly susceptible to significant change in the near term relate to the fair value of debt securities available for sale, fair value of assets acquired and liabilities assumed in business combinations, goodwill, income taxes, and the determination of the ACL. Income Taxes During the three and six months ended June 30, 2024, Busey recorded a one-time deferred tax valuation adjustment of $1.4 million resulting from a change to our Illinois apportionment rate due to recently enacted regulations. These new regulations are expected to lower our ongoing tax obligation in future periods, but create a negative adjustment to the carrying value of our deferred tax asset in the current period. Impact of Recently Adopted Accounting Standards In March 2023, the FASB issued ASU 2023‑02 “Investments—Equity Method and Joint Ventures (Topic 323),” permitting an election to use the proportional amortization method to account for equity investments made primarily for the purpose of receiving income tax credits and other income tax benefits, regardless of the tax credit program from which the income tax credits are received, provided that certain conditions are met. The proportional amortization method results in the cost of the investment being amortized in proportion to the income tax credits and other income tax benefits received, with the amortization of the investment and the income tax credits being presented net in the income statement as a component of income tax expense. Busey adopted this standard on a modified retrospective basis on January 1, 2024. Upon adoption, Busey recorded an after-tax decrease to retained earnings of $1.4 million for the cumulative effect of adopting ASU 2023‑02. This transition adjustment included a $2.4 million decrease in other assets, a $0.5 million decrease in other liabilities, and a $0.5 million increase in deferred tax assets. In March 2023, the FASB issued ASU 2023‑01 “Leases (Topic 842): Common Control Arrangements,” which requires amortization over the useful life of leasehold improvements (not the lease term) when the lease is between entities under common control, and any value of such leasehold improvements remaining at the end of the lease term is to be accounted for as a transfer between entities under common control. Busey adopted this standard on a prospective basis on January 1, 2024. Adoption of this standard did not have a material impact on Busey’s financial position or results of operations. In June 2022, the FASB issued ASU 2022-03 “Fair Value Measurements (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions,” which clarifies that contractual restrictions on the sale of equity securities are not considered in measuring the fair value of those equity securities, and further that contractual sale restrictions cannot be recognized and measured as a separate unit of account. Busey adopted this standard on a prospective basis on January 1, 2024. Adoption of this standard did not have a material impact on Busey’s financial position or results of operations. Recently Issued Accounting Standards Not Yet Adopted In March 2024, the FASB issued ASU 2024-01 “Compensation-Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards” to clarify that certain “profits interests” are within the scope of Topic 718 by amending the language and providing illustrative examples on how the scope guidance in paragraph 718-10-15-3 should be applied. This update is intended to improve clarity of the accounting standards codification, not to change the guidance. This update may be applied on a retrospective or prospective basis and will be effective for Busey for annual and interim periods beginning January 1, 2025. Early adoption is permitted. Busey is currently evaluating the potential effects of adoption of this ASU on its financial position and results of operations. In December 2023, the FASB issued ASU 2023‑09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which requires more detailed disclosures of income taxes paid net of refunds received, income from continuing operations before income tax expense or benefit, and income tax expense from continuing operations. This standard is to be applied on a prospective basis, with retrospective application permitted, and will be effective for Busey for annual reporting periods beginning with the fiscal year ending December 31, 2025. Busey does not expect adoption of this standard to have a material impact on its financial position or results of operations. In November 2023, the FASB issued ASU 2023‑07 “Segment Reporting (Topic 820): Improvements to Reportable Segment Disclosures” requiring enhanced disclosures related to significant segment expenses. This standard is to be applied on a retrospective basis and is effective for Busey for annual reporting periods beginning with the fiscal year ending December 31, 2024, and for interim reporting periods within fiscal years starting January 1, 2025. Busey does not expect adoption of this standard to have a material impact on the Company’s financial position or results of operations. In October 2023, the FASB issued ASU 2023‑06 “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative” which aligns certain GAAP disclosure requirements with the SEC’s disclosure requirements, in order to better facilitate comparisons between entities that are subject to the SEC’s existing disclosures with entities that were not previously subject to the SEC’s requirements. Amendments in this update should be applied prospectively, and the effective date for Busey for each amendment in this ASU will be the date on which the SEC removes the related disclosure from Regulation S‑X or Regulation S‑K. Early adoption is prohibited. Busey does not expect adoption of this standard to have a material impact on its financial position or results of operations. Subsequent Events Busey has evaluated subsequent events for potential recognition and/or disclosure through the date the unaudited consolidated financial statements included in this Quarterly Report were issued. There were no significant events subsequent to the quarter ended June 30, 2024, through the filing date of these unaudited consolidated financial statements.
