Organization and Basis of Presentation |
Organization and Basis of Presentation | ​ First Hawaiian, Inc. (“FHI” or the “Parent”), a bank holding company, owns 100% of the outstanding common stock of First Hawaiian Bank (“FHB” or the “Bank”), its only direct, wholly owned subsidiary. FHB offers a comprehensive suite of banking services, including loans, deposit products, wealth management, insurance, trust, retirement planning, credit card and merchant processing services, to consumer and commercial customers. ​ The accompanying unaudited interim consolidated financial statements of First Hawaiian, Inc. and Subsidiary (the “Company”) have been prepared in accordance with generally accepted accounting principles 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, certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. ​ The accompanying unaudited interim consolidated financial statements and notes thereto should be read in conjunction with the Company’s audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. ​ In the opinion of management, all adjustments, which consist of normal recurring adjustments necessary for a fair presentation of the interim period consolidated financial information, have been made. Results of operations for interim periods are not necessarily indicative of results to be expected for the entire year. Intercompany account balances and transactions have been eliminated in consolidation.
Use of Estimates in the Preparation of Financial Statements | Use of Estimates in the Preparation of Financial Statements ​ The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management’s best knowledge of current events, actual results may differ from these estimates.
Accounting Standards Adopted in 2024 | Accounting Standards Adopted in 2024 ​ In March 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-01, Leases (Topic 842), Common Control Arrangements. This update clarifies the accounting for leasehold improvements associated with common control leases. Prior to this update, Topic 842 generally required leasehold improvements to have an amortization period consistent with the shorter of the useful life of those improvements or the remaining lease term. This update will require leasehold improvements associated with common control leases to be (1) amortized by the lessee over the useful life of the leasehold improvements to the common control group (regardless of the lease term) as long as the lessee controls the use of the underlying asset (the leased asset) through a lease, and (2) accounted for as a transfer between entities under common control through an adjustment to equity if, and when, the lessee no longer controls the use of the underlying asset. In addition, this update also subjects leasehold improvements to the impairment guidance in Topic 360, Property, Plant, and Equipment. The Company adopted the provisions of ASU No. 2023-01 on January 1, 2024, and it did not have a material impact on the Company’s consolidated financial statements. ​ In March 2023, the FASB issued ASU No. 2023-02, Investments—Equity Method and Joint Ventures (Topic 323), Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. This update expands the population of tax equity investments for which a reporting entity may elect to apply the proportional amortization method (“PAM”). Under legacy guidance, an entity can only elect to apply the PAM to investments in low-income housing tax credit (“LIHTC”) structures. This update permits an entity to make an election to account for tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the PAM if certain conditions are met. An accounting policy election is made to apply the PAM on a tax credit program-by-program basis rather than electing to apply the PAM at the reporting entity level or to individual investments. By applying the PAM, a reporting entity must account for the receipt of the investment tax credits using the flow-through method under Topic 740, Income Taxes, even if the entity applies the deferral method for other investment tax credits received. For all tax equity investments accounted for using the PAM, this update also requires the use of the delayed equity contribution guidance. LIHTC investments not accounted for using the PAM will no longer be permitted to use the delayed equity contribution guidance. In addition, LIHTC investments accounted for using the equity method must apply the impairment guidance in Subtopic 323-10, Investments—Equity Method and Joint Ventures—Overall. Further, LIHTC investments that are not accounted for using the PAM or the equity method must use the guidance in Topic 321, Investments—Equity Securities, when accounting for equity investments. In addition, the amendments in this update require specific disclosures that must be applied to all investments that generate income tax credits and other income tax benefits from a tax credit program for which the entity has elected to apply the PAM, including investments within that elected program that do not meet the conditions to apply the PAM. Such disclosures include the nature of its tax equity investments and the effect of such investments and related income tax credits and other income tax benefits on its financial position and results of operations. The Company adopted the provisions of ASU No. 2023-02 on January 1, 2024, and it did not have a material impact on the Company’s consolidated financial statements. See “Note 5. Other Assets” for required disclosures related to this new guidance.
Recent Accounting Pronouncements | Recent Accounting Pronouncements ​ The following ASUs have been issued by the FASB and are applicable to the Company in future reporting periods. ​ In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures. This update improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments will require public entities to disclose significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within segment profit or loss, an amount and description of its composition for other segment items to reconcile to segment profit or loss, and the title and position of the entity’s CODM. In addition, the amendments clarify circumstances in which an entity can disclose multiple measures of segment profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and expand interim disclosure requirements. The purpose of the amendments is to enable investors to better understand an entity’s overall performance and assess potential future cash flows. The amendments are effective for the Company’s annual periods beginning January 1, 2024 and interim periods beginning January 1, 2025, with early adoption permitted, and requires retrospective application to all prior periods presented in the financial statements. The Company is currently evaluating the impact of the incremental segment information that will be required to be disclosed as well as the impact to the Reportable Operating Segments footnote. ​ In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740), Improvements to Income Tax Disclosures. This update includes amendments that further enhance the transparency and decision usefulness of income tax disclosures, primarily through standardizing and disaggregating rate reconciliation categories and income taxes paid by jurisdiction. This update is effective for the Company’s annual periods beginning January 1, 2025. Early adoption is permitted. The Company is currently evaluating the impact of the incremental income taxes information that will be required to be disclosed as well as the impact to the Income Taxes footnote. ​
