Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business, Basis of Presentation and Significant Accounting Policies	Description of Business The Company is primarily engaged in the business of planning, directing and coordinating the business activities of its wholly-owned subsidiary, the Bank. The Bank is headquartered in Olympia, Washington and conducts business from its 50 branch offices located throughout Washington State, the greater Portland, Oregon area, Eugene, Oregon and Boise, Idaho. The Bank’s business consists primarily of commercial lending and deposit relationships with small and medium-sized businesses and their owners in its market areas and attracting deposits from the general public. The Bank also makes real estate construction and land development loans, consumer loans and originates first mortgage loans on residential properties primarily located in its market areas. The Bank's deposits are insured by the FDIC subject to limitations. (b) Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with GAAP for interim financial information and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. It is recommended these unaudited Condensed Consolidated Financial Statements and accompanying Notes be read with the audited Consolidated Financial Statements and the accompanying Notes included in the 2022 Annual Form 10-K. In management's opinion, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the nine months ended September 30, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023. The accompanying Condensed Consolidated Financial Statements presented for the year end December 31, 2022 were derived from audited financial statements and do not include all disclosures required by GAAP. To prepare unaudited Condensed Consolidated Financial Statements in conformity with GAAP, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided. Management believes the judgments, estimates and assumptions used in the preparation of the unaudited Condensed Consolidated Financial Statements are appropriate based on the facts and circumstances at the time. Actual results, however, could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change relate to management's estimate of the ACL on investment securities, management's estimate of the ACL on loans, management's estimate of the ACL on unfunded commitments, management's evaluation of goodwill impairment and management's estimate of the fair value of financial instruments. The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiary, the Bank. All significant intercompany balances and transactions among the Company and the Bank have been eliminated in consolidation. There have been reclassifications in certain prior year amounts in the unaudited Condensed Consolidated Statements of Income. Reclassifications had no effect on the prior year's net income or stockholders’ equity. (c) Significant Accounting Policies The significant accounting policies used in preparation of the unaudited Condensed Consolidated Financial Statements are disclosed in greater detail in the 2022 Annual Form 10-K. There have not been any material changes in the Company's significant accounting policies from those contained in the 2022 Annual Form 10-K during the nine months ended September 30, 2023.
Recently Issued or Adopted Accounting Pronouncements	Recently Issued or Adopted Accounting Pronouncements FASB ASU 2020-04, Reference Rate Reform (Topic 848), as amended by ASU 2021-01, and ASU 2022-06 was issued in March 2020 and provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this ASU are effective for all entities as of March 12, 2020. In December 2022, FASB amended this ASU and deferred the sunset date of Topic 848 from December 31, 2022, to December 31, 2024. The amendments are elective, apply to all entities, and provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. Effective January 25, 2021, the Company adhered to the Interbank Offered Rate Fallbacks Protocol as published by the International Swaps and Derivatives Association, Inc. and recommended by the Alternative Reference Rates Committee. The majority of the Bank’s interest rate swap-related transactions indexed to LIBOR were transferred to another index during the three months ended June 30, 2023. The remaining instruments including loans and investments are either in the process of transition or will transition to a new index at the next repricing date. The Company does not expect the adoption of this ASU to have a material impact on its business operations or Consolidated Statements of Financial Condition. FASB ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures, was issued in March 2022. The ASU eliminates the accounting guidance for TDR loans by creditors while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Specifically, rather than applying the recognition and measurement guidance for TDRs, the entity will apply the loan refinancing and restructuring guidance to determine whether a modification or other form of restructuring results in a new loan or continuation of an existing loan. Additionally, the ASU requires public business entities to disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases. These amendments are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted in any interim period if an entity has adopted ASU 2016-13 and such election may be made individually to adopt the guidance related to TDRs, including related disclosures, and the presentation of gross write-offs in the vintage disclosure. This update requires prospective transition for the disclosures related to loan restructurings for borrowers experiencing financial difficulty and the presentation of gross write-offs in the vintage disclosures. The guidance related to the recognition and measurement of TDRs may be adopted on a prospective or modified retrospective transition method. The Company adopted ASU 2022-02 on a prospective basis January 1, 2023. The Company elected at the date of adoption to account for existing TDR loans as of December 31, 2022 under the Company's TDR accounting policy which is disclosed in the 2022 Annual Form 10-K. All loan modifications post adoption are accounted for under the loan modification guidance in ASC 310-20. The adoption of this ASU did not have a material impact on business operations or the Consolidated Statements of Financial Condition. FASB ASU 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (a consensus of the Emerging Issues Task Force), was issued in February 2023. The amendments in this ASU permit companies to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method, if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the income tax credits and other income tax benefits received and recognizes the net amortization and income tax credits and other income tax benefits in the statement of operations as a component of income tax expense (benefit). The amendments also require that a reporting entity disclose certain information in annual and interim reporting periods that enable investors to understand the investments that generate income tax credits and other income tax benefits from a tax credit program. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023, with early adoption permitted. The amendments in the ASU can be applied either on a modified retrospective or a retrospective basis. The Company does not expect the adoption of this ASU to have a material impact on its business operations or Consolidated Statements of Financial Condition.
Loans Receivable Concentrations of Credit	Concentrations of CreditMost of the Bank’s lending activity occurs within its primary market areas which are concentrated along the I-5 corridor from Whatcom County, Washington to Lane County, Oregon, as well as Yakima County in Washington and Ada County in Idaho. Additionally, the Bank's loan portfolio is concentrated in commercial business loans, which include commercial and industrial, owner-occupied and nonowner-occupied CRE, and commercial and multifamily real estate construction and land development loans. Commercial business loans are generally considered as having a more inherent risk of default than residential real estate loans or other consumer loans. Also, the commercial loan balance per borrower is typically larger than that for residential real estate loans and consumer loans, implying higher potential losses on an individual loan basis
ACL on Investment Securities	ACL on Investment Securities The Company evaluated investment securities available for sale as of September 30, 2023 and December 31, 2022 and determined that any declines in fair value were attributable to changes in interest rates relative to where these investments fall within the yield curve and individual characteristics. Management monitors published credit ratings for adverse changes for all rated investment securities and none of these securities had a below investment grade credit rating as of both September 30, 2023 and December 31, 2022. In addition, the Company does not intend to sell these securities nor does the Company consider it more likely than not that it will be required to sell these securities before the recovery of the amortized cost basis, which may be upon maturity. Therefore, no ACL on investment securities available for sale was recorded as of September 30, 2023 and December 31, 2022. The Company also evaluated investment securities held to maturity for current expected credit losses as of September 30, 2023 and December 31, 2022. There were no investment securities held to maturity classified as nonaccrual or past due as of September 30, 2023 and December 31, 2022 and all were issued by the U.S. government and its agencies and either explicitly or implicitly guaranteed by the U.S. government, highly rated by major credit rating agencies and had a long history of no credit losses. Accordingly, the Company did not measure expected credit losses on investment securities held to maturity since the historical credit loss information adjusted for current conditions and reasonable and supportable forecasts results in an expectation that nonpayment of the amortized cost basis is zero. Therefore, no ACL on investment securities held to maturity was recorded as of September 30, 2023 and December 31, 2022.
Loans Receivable Credit Quality Indicators	Credit Quality Indicators As part of the on-going monitoring of the credit quality of the Bank’s loan portfolio, management tracks certain credit quality indicators including trends related to (i) the risk grade of the loans, (ii) the level of classified loans, (iii) net charge-offs, (iv) nonperforming loans, (v) past due status, and (vi) the general economic conditions of the United States of America, and specifically the states of Washington and Oregon. The Bank utilizes a risk grading matrix to assign a risk grade to each of its loans. Loans are graded on a scale of 1 to 10. Risk grades are aggregated to create the risk categories of Pass for grades 1 to 6, Special Mention or "SM" for grade 7, Substandard or "SS" for grade 8, Doubtful for grade 9 and Loss for grade 10. Descriptions of the general characteristics of the risk grades, including qualitative information on how the risk grades relate to the risk of loss, are contained in the 2022 Annual Form 10-K. Numerical loan grades for loans are established at the origination of the loan. Changes to loan grades are considered at the time new information about the performance of a loan becomes available, including the receipt of updated financial information from the borrower, results of annual term loan reviews and scheduled loan reviews. For consumer loans, the Bank follows the FDIC’s Uniform Retail Credit Classification and Account Management Policy for subsequent classification in the event of payment delinquencies or default. Typically, an individual loan grade will not be changed from the prior period unless there is a specific indication of credit deterioration or improvement. Credit deterioration is evidenced by delinquency, direct communications with the borrower or other borrower information that becomes known to management. Credit improvements are evidenced by known facts regarding the borrower or the collateral property. Loan grades relate to the likelihood of losses in that the higher the grade, the greater the loss potential. Loans with a pass grade may have some estimated inherent losses, but to a lesser extent than the other loan grades. The SM loan grade is transitory in that the Bank is waiting on additional information to determine the likelihood and extent of any potential loss. The likelihood of loss for SM graded loans, however, is greater than Watch graded loans because there has been measurable credit deterioration. Loans with a SS grade have further credit deterioration and include both accrual loans and nonaccrual loans. For Doubtful and Loss graded loans, the Bank is almost certain of the losses and the outstanding principal balances are generally charged off to the realizable value.
Commitments and Contingencies	Commitments and ContingenciesIn the ordinary course of business, the Bank may enter into various types of transactions that include commitments to extend credit that are not included in its unaudited Condensed Consolidated Financial Statements. The Bank applies the same credit standards to these commitments as it uses in all its lending activities and has included these commitments in its lending risk evaluations. The majority of the commitments presented below are variable rate. Loan commitments can be either revolving or non-revolving. The Bank’s exposure to credit and market risk under commitments to extend credit is represented by the amount of these commitments.
