Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: HomeStreet, Inc., a State of Washington corporation organized in 1921 (the "Corporation"), is a Washington-based diversified financial services holding company whose operations are primarily conducted through its wholly owned subsidiaries (collectively the "Company") HomeStreet Statutory Trusts and HomeStreet Bank (the "Bank"), and the Bank's subsidiaries, Continental Escrow Company, HS Properties, Inc., HS Evergreen Corporate Center LLC, and Union Street Holdings LLC. The Company is principally engaged in commercial banking, mortgage banking and consumer/retail banking activities serving customers in the Western United States. The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP"). The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant inter-company accounts and transactions have been eliminated in consolidation. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting periods. Actual results could differ significantly from those estimates. Certain amounts in the financial statements from prior periods have been reclassified to conform to the current financial statement presentation. These unaudited interim financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the periods presented. These adjustments are of a normal recurring nature, unless otherwise disclosed in this Quarterly Report on Form 10-Q. The results of operations in the interim financial statements do not necessarily indicate the results that may be expected for the full year. The interim financial information should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2024 ("2024 Annual Report on Form 10-K"), filed with the U.S. Securities and Exchange Commission ("SEC"). Segments Our chief operating decision maker (“CODM”), the Chief Executive Officer, manages the Company’s business activities as one single operating and reportable segment at the consolidated level. Accordingly, our CODM uses consolidated net income to measure segment profit or loss, allocate resources and assess performance. Further, the CODM reviews and utilizes net interest income, noninterest income and noninterest expenses (compensation and benefits, information services, occupancy and general, administrative and other) at the consolidated level to manage the Company’s operations. Recent Developments On March 28, 2025, the Company entered into a definitive merger agreement with Mechanics Bank, whereby the Company and the Bank will merge with and into Mechanics Bank. This merger is expected to close in the third quarter of 2025. Recent Accounting Developments In October 2023, the FASB issued ASU 2023-06, "Disclosure Improvements - Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative." The amendments in ASU 2023-06 modify the disclosure or presentation requirements of a variety of Topics in the Codification, with the intention of clarifying or improving them and aligning the requirements in the codification with the SEC's regulations (and will be removed from the SEC regulations). ASU 2023-06 should be adopted prospectively, and the effective date varies and is determined for each individual disclosure based on the effective date of the SEC's removal of the related disclosure. We are assessing the impact of ASU 2023-06 and believe it will not have an impact on the Company's financial position or results of operation as it impacts disclosures only. In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures", which expands disclosures in an entity’s income tax rate reconciliation table and taxes paid both in the U.S. and foreign jurisdictions. The update will be effective for annual periods beginning after December 15, 2024. The adoption of ASU 2023-09 will not have an impact on the Company's financial position or results of operation as it impacts disclosures only. We are assessing the impact on our disclosures. In November 2024, the FASB issued ASU 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” ASU 2024-03 requires public companies to disclose, in the notes to the financial statements, specific information about certain costs and expenses at each interim and annual reporting period. This includes disclosing amounts related to employee compensation, depreciation, and intangible asset amortization. In addition, public companies will need to provide qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively. ASU 2024-03 is effective for public business entities for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Implementation of ASU 2024-03 may be applied prospectively or retrospectively. The adoption of ASU 2024-03 will not have an impact on the Company's financial position or results of operation as it impacts disclosures only. We are assessing the impact on our disclosures.
