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, HomeStreet Foundation, 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 primarily 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. The Company allocates resources and assesses financial performance on a consolidated basis and therefore has one reporting segment. 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, 2023 ("2023 Annual Report on Form 10-K"), filed with the U.S. Securities and Exchange Commission ("SEC"). Branch Acquisition On February 10, 2023, the Company completed its acquisition of three branches in southern California, whereby we assumed approximately $376 million in deposits and purchased approximately $21 million in loans. The application of the acquisition method of accounting resulted in recording goodwill of $12 million and a core deposit intangible of $11 million. Merger On April 30, 2024, the Company entered into Amendment No. 1 to the previously announced definitive merger agreement with FirstSun Capital Bancorp (“FirstSun”), the holding company of Sunflower Bank, N.A ("Sunflower Bank"), and Dynamis Subsidiary, Inc., whereby, under the merger agreement, as amended, the Company and the Bank will merge with and into FirstSun and Sunflower Bank, respectively (collectively, the "Merger"). Subject to terms and conditions of the merger agreement, as amended, the companies will combine in an all-stock transaction in which HomeStreet shareholders will receive 0.3867 of a share of FirstSun common stock for each share of HomeStreet common stock. The parties to the Merger expect to complete the Merger in late 2024, subject to the satisfaction of closing conditions, including receipt of required regulatory approvals and satisfaction or waiver of other closing conditions. 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 align 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. ASU 2023-06 will not have an impact on the Company's financial position or results of operation as it is disclosure only. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which expands disclosures about a public entity’s reportable segments and requires more enhanced information about a reportable segment’s expenses, interim segment profit or loss, and how a public entity’s chief operating decision maker uses reported segment profit or loss information in assessing segment performance and allocating resources. The update will be effective for annual periods beginning after December 15, 2023. ASU 2023-07 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 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 regarding cash taxes paid both in the U.S. and foreign jurisdictions. The update will be effective for annual periods beginning after December 15, 2024. 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
