Basis Of Presentation [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements included herein have been prepared without an audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”), except for the Consolidated Statement of Financial Condition at December 31, 2022, which was from the audited financial statements included in the Company’s 2022 Annual Report on Form 10-K. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such SEC rules and regulations. The consolidated financial statements include the accounts of Hope Bancorp and its wholly owned subsidiaries, principally Bank of Hope. All intercompany transactions and balances have been eliminated in consolidation. The Company has made all adjustments, that, in the opinion of management, are necessary to fairly present the Company’s financial position at June 30, 2023 and December 31, 2022, and the results of operations for the three and six months ended June 30, 2023 and 2022. Certain reclassifications have been made to prior period amounts to conform to the current year presentation. The results of operations for the interim periods are not necessarily indicative of results to be anticipated for the full year. The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“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. Actual results could differ significantly from those estimates. These unaudited consolidated financial statements should be read along with the audited consolidated financial statements and accompanying notes included in the Company’s 2022 Annual Report on Form 10-K. Significant Accounting Policies Our accounting policies are described in Note 1 - Summary of Significant Accounting Policies, of our audited consolidated financial statements included in our 2022 Annual Report Form 10-K. Significant changes to accounting policies from those disclosed in our audited consolidated financial statements included in our 2022 Annual Report Form 10-K are presented below. Loan Modifications to Borrowers Experiencing Financial Difficulty. Prior to the adoption of ASU 2022-02, we accounted for the modification to the contractual terms of a loan that resulted in granting a concession to a borrower experiencing financial difficulties as a troubled debt restructuring (“TDR”). Effective January 1, 2023, we adopted ASU 2022-02, which eliminated TDR accounting prospectively for all restructurings occurring on or after January 1, 2023. Loans that were considered a TDR prior to the adoption of ASU 2022-02 will be collectively evaluated for Allowance for Credit Losses (“ACL”) purposes until the loan is paid off, liquidated, or subsequently modified. Since adoption of ASU 2022-02 on January 1, 2023, we have evaluated all loan modifications under ASC 310-20 to determine whether a modification made to a borrower results in a new loan or is a continuation of the existing loan. GAAP requires the Company to make certain disclosures related to these loans, including certain types of modifications, as well as how such loans have performed since their modifications. Please see Note 6—“Loans Receivable and Allowance for Credit Losses” for additional information concerning loan modifications to borrowers experiencing financial difficulty.
