Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation Bank of Hawaii Corporation (the “Parent”) is a Delaware corporation and a bank holding company headquartered in Honolulu, Hawai‘i. Bank of Hawaii Corporation and its subsidiaries (collectively, the “Company”), provide a broad range of financial products and services to customers in Hawai‘i, Guam and other Pacific Islands. The majority of the Company’s operations consist of customary commercial and consumer banking services including, but not limited to, lending, leasing, deposit services, trust and investment activities, brokerage services, and trade financing. The accompanying Unaudited Consolidated Financial Statements include the accounts of the Parent and its subsidiaries. The Parent’s principal operating subsidiary is Bank of Hawai‘i (the “Bank”). The Consolidated Financial Statements in this report have not been audited by an independent registered public accounting firm, but, in the opinion of management, reflect all adjustments necessary for a fair presentation of the results for the interim periods. All such adjustments are of a normal recurring nature. Intercompany accounts and transactions have been eliminated in consolidation. Certain prior period information has been reclassified to conform to the current period presentation. Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for the full fiscal year or any future period. The accompanying Unaudited Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and accompanying notes required by GAAP for complete financial statements and should be read in conjunction with the audited Consolidated Financial Statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024. Significant changes to accounting policies from those disclosed in our audited Consolidated Financial Statements and related notes included in the Company’s Annual Report on Form 10-K are presented below. Certain prior period information has been reclassified to conform to the current year presentation.
