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 Capital Corporation, 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, 2021, filed with the Securities and Exchange Commission ("2021 Annual Report on Form 10-K"). Goodwill Goodwill is recorded upon completion of a business combination as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill has been determined to have an indefinite useful life and is not amortized, but tested for impairment at least annually or more frequently if events and circumstances occur that indicate it is more likely than not the fair value of the reporting unit is less than its carrying value necessitating an impairment test. Historically, the Company performed its annual impairment testing on June 30. In 2022, we moved the annual impairment testing date to August 31 and based on that testing determined goodwill was not impaired. The change in impairment date did not have a material effect on the Company’s financial position or results of operations. Dispositions In July 2022, we closed a sale of five retail deposit branches in eastern Washington, including the branches' lending businesses and employees. As part of this transaction, we transferred $191 million of deposits, sold $43 million of loans and recognized a gain on sale of $4.3 million. Recent Accounting Developments In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2020-04, Reference Rate Reform (Topic 848). This ASU provides optional expedients and exceptions for contracts, hedging relationships, and other transactions that reference London Interbank Offered Rate ("LIBOR") rates expected to be discontinued because of reference rate reform. In January 2021, the FASB issued ASU 2021-01, "Reference Rate Reform (Topic 848)," which clarifies certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting applied to derivatives that are affected by the transition to alternative rates. The ASUs are effective for all entities as of March 12, 2020 through December 31, 2022. The adoption of these ASUs is not expected to have a material impact on the Company’s financial position or results of operations. In March 2022, the FASB issued ASU No. 2022-02, Financial Instruments-Credit Losses (Topic 326). The amendments in this ASU eliminate the accounting guidance for Troubled Debt Restructuring ("TDRs") by creditors, while enhancing disclosure requirements for certain loan refinancing and restructurings by creditors when a borrower experiences financial difficulty. In addition, the amendments require that an entity disclose current period gross charge-offs by year of origination in a vintage table. We prospectively adopted the portion of ASU No. 2022-02 with respect to amendments about TDRs and related disclosure enhancements as of January 1, 2022. This adoption did not have a material impact on the Company’s financial position or results of operations. As the change is disclosure only in nature, we do not expect the vintage table disclosure requirement of ASU 2022-02 to have a material impact on the Company's financial position or results of operations when adopted.
