Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business, Basis of Presentation and Significant Accounting Policies and Recently Issued Accounting Pronouncements	Description of Business, Basis of Presentation, Significant Accounting Policies and Recently Issued Accounting Pronouncements (a) 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 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 2023 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 three months ended March 31, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. The accompanying Condensed Consolidated Financial Statements presented for the year end December 31, 2023 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. (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 2023 Annual Form 10-K. There have not been any material changes in the Company's significant accounting policies during the three months ended March 31, 2024 from those contained in the 2023 Annual Form 10-K. (d) 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 Company’s instruments indexed to LIBOR were transferred to another index during the year ended December 31, 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. 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 had already applied proportional amortization to its LIHTC investments prior to January 1, 2024. The amendments in this ASU allow the Company to expand the use of proportional amortization to other types of qualifying tax credit investments. The Company has chosen not to expand the use of proportional amortization beyond its LIHTC investment portfolio. Thus, at this time, this ASU only impacts disclosure requirements.

(c) ACL on Investment Securities The Company evaluated investment securities available for sale as of March 31, 2024 and December 31, 2023, 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 either March 31, 2024 or December 31, 2023. 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 March 31, 2024 and December 31, 2023. The Company also evaluated investment securities held to maturity for current expected credit losses as of March 31, 2024 and December 31, 2023. There were no investment securities held to maturity classified as nonaccrual or past due as of March 31, 2024 and December 31, 2023, 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 March 31, 2024 and December 31, 2023. (d) Realized Gains and Losses The following table presents the gross realized gains and losses on the sale of investment securities available for sale determined using the specific identification method for the dates indicated: Three Months Ended March 31, 2024 2023 (Dollars in thousands) Gross realized gains $ — $ 36 Gross realized losses (9,973) (322) Net realized losses $ (9,973) $ (286) (e) Pledged Securities The following table summarizes the amortized cost and fair value of investment securities that were pledged as collateral for the following obligations at the dates indicated: March 31, 2024 December 31, 2023 Amortized Fair Amortized Fair (Dollars in thousands) State and local governments public deposits $ 235,829 $ 219,951 $ 238,060 $ 224,879 FRB 619,972 520,685 845,098 742,197 Other securities pledged 54,376 48,457 54,636 49,032 Total $ 910,177 $ 789,093 $ 1,137,794 $ 1,016,108 (f) Accrued Interest Receivable Accrued interest receivable excluded from the amortized cost of investment securities available for sale totaled $3.6 million and $3.8 million at March 31, 2024 and December 31, 2023, respectively. Accrued interest receivable excluded from the amortized cost on investment securities held to maturity totaled $2.2 million and $2.3 million at March 31, 2024 and December 31, 2023, respectively. No amounts of accrued interest receivable on investment securities available for sale or held to maturity were reversed against interest income on investment securities during the three months ended March 31, 2024 and 2023.

Receivables [Abstract]
Loans Receivable	Loans Receivable The Company originates loans in the ordinary course of business and has also acquired loans through mergers and acquisitions. Accrued interest receivable was excluded from disclosures presenting the Company's amortized cost of loans receivable as it was deemed insignificant. In addition to originating loans, the Company may also purchase loans through pool purchases, participation purchases and syndicated loan purchases. (a) Loan Origination/Risk Management The Company categorizes the individual loans in the total loan portfolio into four segments: commercial business; residential real estate; real estate construction and land development; and consumer. Within these segments are classes of loans for which management monitors and assesses credit risk in the loan portfolios. A detailed description of the portfolio segments and classes is contained in the 2023 Annual Form 10-K. The Company has certain lending policies and guidelines in place that are designed to maximize loan income within an acceptable level of risk. Management reviews and approves these policies and guidelines on a regular basis. A reporting system supplements the review process by providing management with frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies and nonperforming and criticized loans. The Company also conducts internal loan reviews and validates the credit risk assessment on a periodic basis and presents the results of these reviews to management. The loan review process complements and reinforces the risk identification and assessment decisions made by loan officers and credit personnel. The amortized cost of loans receivable, net of ACL on loans, consisted of the following portfolio segments and classes at the dates indicated: March 31, 2024 December 31, 2023 (Dollars in thousands) Commercial business: Commercial and industrial $ 760,391 $ 718,291 March 31, 2024 December 31, 2023 (Dollars in thousands) Owner-occupied CRE 951,583 958,620 Non-owner occupied CRE 1,702,665 1,697,574 Total commercial business 3,414,639 3,374,485 Residential real estate 386,357 375,342 Real estate construction and land development: Residential 84,081 78,610 Commercial and multifamily 372,532 335,819 Total real estate construction and land development 456,613 414,429 Consumer 170,556 171,371 Loans receivable 4,428,165 4,335,627 ACL on loans (49,736) (47,999) Loans receivable, net $ 4,378,429 $ 4,287,628 Balances included in the amortized cost of loans receivable: Unamortized net discount on acquired loans $ (1,701) $ (1,923) Unamortized net deferred fee $ (10,477) $ (11,063) (b) Concentrations of Credit Most of the Company’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 Company'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 and commercial and multifamily real estate construction and land development 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. (c) Credit Quality Indicators As part of the on-going monitoring of the credit quality of the Company’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, Oregon and Idaho. The Company 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 2023 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 Company 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 Company 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 pass 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 Company is almost certain of the losses and the outstanding principal balances are generally charged off to the realizable value. There were no loans graded doubtful or loss as of March 31, 2024 and December 31, 2023.

At December 31, 2023, there were $6.6 million in commitments to lend additional funds to borrowers experiencing financial difficulty whose terms have been modified during the year ended December 31, 2023. The Company closely monitors the performance of loans that are modified for borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts. The Company considers a modified loan as a payment default if the borrower is 90 or more days past due. There were no loans past due or in default that have been modified in the past 12 months. (h) Accrued interest receivable on loans receivable Accrued interest receivable on loans receivable totaled $13.8 million and $13.3 million at March 31, 2024 and December 31, 2023, respectively, and is excluded from the calculation of the ACL on loans as interest accrued, but not received, is reversed timely. (i) Foreclosure proceedings in process At March 31, 2024, there were no consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings were in process.

Allowance for Credit Loss [Abstract]
Allowance for Credit Losses on Loans	Allowance for Credit Losses on Loans The Company's methodology for determining the ACL on loans is based upon key assumptions, including the lookback periods, historic net charge-off factors, economic forecasts, reversion periods, prepayments and qualitative adjustments. The allowance is measured on a collective, or pool, basis when similar risk characteristics exist. Loans that do not share common risk characteristics are evaluated on an individual basis and are excluded from the collective evaluation. For a description of the Company's ACL policy, see Note 1 - Description of Business, Basis of Presentation, Significant Accounting Policies and Recently Issued Accounting Pronouncements included in Item 8. Financial Statements And Supplementary Data in our 2023 Annual Form 10-K. GAAP requires the Company to develop reasonable and supportable forecasts of future conditions, and estimate how those forecasts are expected to impact a borrower’s ability to satisfy their obligation to the Company and the ultimate collectability of future cash flows over the life of a loan. Management has adopted a historic loss, open pool CECL methodology to calculate the ACL on loans. Under this methodology, loans are either collectively evaluated if they share similar risk characteristics, including performing modified loans, or individually evaluated if they do not share similar risk characteristics, including nonaccrual loans. The allowance for individually evaluated loans is calculated using either the collateral value method, which considers the likely source of repayment as the value of the collateral less estimated costs to sell, or the net present value method, which considers the contractual principal and interest terms and estimated cash flows available from the borrower to satisfy the debt. The allowance for collectively evaluated loans is comprised of the baseline loss allowance, the macroeconomic allowance and the qualitative allowance. The baseline loss allowance begins with the baseline loss rates calculated using the Company's average quarterly historical loss information for an economic cycle. The Company evaluates the historical period on a quarterly basis with the assumption that economic cycles have historically lasted between 10 and 15 years. The baseline loss rates are applied to each loan's estimated cash flows over the life of the loan under the remaining life method to determine the baseline loss estimate for each loan. Estimated cash flows consider the principal and interest in accordance with the contractual term of the loan and estimated prepayments. Contractual cash flows are based on the amortized cost and are adjusted for balances guaranteed by governmental entities, such as Small Business Administration or USDA, resulting in the unguaranteed amortized cost. The contractual term excludes expected extensions, renewals and modifications unless the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by the Company. Prepayments are established for each segment based on historical averages for the segment, which management believes is an accurate representation of future prepayment activity. Management reviews the adequacy of the prepayment assumption on a quarterly basis. The macroeconomic allowance includes consideration of the forecasted direction of the economic and business environment and its likely impact on the estimated allowance as compared to the historical losses over the reasonable and supportable time frame. The Company uses macroeconomic scenarios from an independent third party. These scenarios are based on past events, current conditions, the likelihood of future events occurring and include consideration of the forecasted direction of the economic and business environment and its likely impact on the estimated allowance as compared to the historical losses over the reasonable and supportable time frame. Economic forecast models for the current period are uploaded to the model, which targets certain forecasted macroeconomic factors, such as unemployment rate, gross domestic product, housing price index, commercial real estate price index, and certain rate and market indices. Macroeconomic factor multipliers are determined through regression analysis and applied to loss rates for each segment of loans with similar risk characteristics. Each of the forecasted segment balances is impacted by a mix of these macroeconomic factors. Further, each of the macroeconomic factors is utilized differently by segment, including the application of lagged factors and various transformations such as percent change year over year. A macroeconomic sensitive model is developed for each segment given the current and forecasted conditions and a macroeconomic multiplier is calculated for each forecast period considering the forecasted losses as compared to the long-term average actual losses of the dataset. The impact of those macroeconomic factors on each segment, both positive or negative, using the reasonable and supportable period, are added to the calculated baseline loss allowance. After the reasonable and supportable period, forecasted loss rates revert to historical baseline loss levels over the predetermined reversion period on a straight-lined basis. The Company’s ACL model also includes adjustments for qualitative factors, where appropriate. Since historical information (such as historical net losses and economic cycles) may not always, by themselves, provide a sufficient basis for determining future expected credit losses, the Company periodically considers the need for qualitative adjustments to the ACL. Qualitative adjustments may be related to and include, but not be limited to, factors such as: (i) management’s assessment of economic forecasts used in the model and how those forecasts align with management’s overall evaluation of current and expected economic conditions, (ii) organization specific risks such as credit concentrations, collateral specific risks, regulatory risks, and external factors that may ultimately impact credit quality, (iii) potential model limitations such as those identified through back-testing, underwriting changes, acquisition of new portfolios and changes in portfolio segmentation, and (iv) management’s overall assessment of the adequacy of the ACL, including an assessment of model data inputs used to determine the ACL. As of March 31, 2024, qualitative adjustments primarily related to certain segments of the loan portfolio deemed by management to be of a higher-risk profile where management believes the quantitative component of the Company’s ACL model may not have fully captured the associated impact to the ACL. Qualitative adjustments also related to heightened uncertainty as to future macroeconomic conditions and the related impact on certain loan segments. Management reviews the need for an appropriate level of qualitative adjustments on a quarterly basis, and as such, the amount and allocation of qualitative adjustments may change in future periods. In general, management's estimate of the ACL on loans uses relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. The evaluation of ACL on loans is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. While management utilizes its best judgment and information available to recognize estimated losses on loans, future additions to the ACL may be necessary based on further declines in local and national economic conditions. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Company’s ACL on loans. Such agencies may require the Company to adjust the ACL based on their judgments about information available to them at the time of their examinations. The Company believes the ACL on loans is appropriate given all the above considerations. During the three months ended March 31, 2024, the ACL on loans increased $1.7 million to $49.7 million from $48.0 million at December 31, 2023 due primarily to growth in loans receivable, net.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments The Company utilizes interest rate swap derivative contracts to facilitate the needs of its commercial customers whereby it enters into an interest rate swap with a customer while at the same time entering into an offsetting interest rate swap with another financial institution. The transaction allows the Company’s customer to effectively convert a variable rate loan to a fixed rate loan, or a fixed rate loan to a variable rate loan, and the Company recognizes immediate income based upon the difference in the bid/ask spread of the underlying transactions with its customers and the third-party. These interest rate swaps are not designated as hedging instruments. The Company is exposed to interest rate risk as part of the transaction. However, the Company acts as an intermediary for its customer therefore changes in the fair value of the underlying derivative contracts for the most part offset each other and do not significantly impact the Company’s results of operations. Fee income related to interest rate swap derivative contract transactions is recorded in Interest rate swap fees on the unaudited Condensed Consolidated Statements of Income. The fair value of derivative positions outstanding is included in Prepaid expenses and other assets and Accrued expenses and other liabilities in the unaudited Condensed Consolidated Statements of Financial Condition. The gains and losses due to changes in fair value and all cash flows are included in Other income in the unaudited Condensed Consolidated Statements of Income, but typically net to zero based on the identical back-to-back interest rate swap derivative contracts unless a credit valuation adjustment is recorded to appropriately reflect nonperformance risk in the fair value measurement. Various factors impact changes in the credit valuation adjustments over time, including changes in the risk ratings of the parties to the contracts, as well as changes in market rates and volatilities, which affect the total expected exposure of the derivative instruments. The following table presents the notional amounts and estimated fair values of interest rate derivative contracts outstanding at the dates indicated: March 31, 2024 December 31, 2023 Notional Amounts Estimated Fair Value Notional Amounts Estimated Fair Value (Dollars in thousands) Non-hedging interest rate derivatives Interest rate swap asset (1) $ 289,528 26,837 $ 291,740 $ 23,195 Interest rate swap liability (1) 289,528 (26,837) 291,740 (23,195) (1) The estimated fair value of derivatives with customers was $(26.5) million and $(22.5) million as of March 31, 2024 and December 31, 2023, respectively. The estimated fair value of derivatives with third-parties was $26.5 million and $22.5 million as of March 31, 2024 and December 31, 2023, respectively. The Company is exposed to credit-related losses in the event of nonperformance by the counterparty to these agreements. Credit risk for derivatives with the customer is controlled through the credit approval process, amount limits, and monitoring procedures and is concentrated within our primary market areas. Credit risk for derivatives with third-parties is concentrated among four well-known broker dealers.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is the price that would be received to sell an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. There are three levels of inputs that may be used to measure fair values: Level 1 : Valuations for assets and liabilities traded in active exchange markets, or interest in open-end mutual funds that allow the Company to sell its ownership interest back to the fund at net asset value on a daily basis. Valuations are obtained from readily available pricing sources for market transactions involving identical assets, liabilities, or funds. Level 2 : Valuations for assets and liabilities traded in less active dealer or broker markets, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or valuations using methodologies with observable inputs. Level 3 : Valuations for assets and liabilities that are derived from other valuation methodologies, such as option pricing models, discounted cash flow models and similar techniques using unobservable inputs, and not based on market exchange, dealer, or broker traded transactions. Level 3 valuations incorporate certain assumptions and projections in determining the fair value assigned to such assets or liabilities. (a) Recurring and Nonrecurring Basis The Company used the following methods and significant assumptions to measure the fair value of certain assets on a recurring and nonrecurring basis: Investment Securities : The fair values of all investment securities are based upon the assumptions that market participants would use in pricing the security. If available, fair values of investment securities are determined by quoted market prices (Level 1). For investment securities where quoted market prices are not available, fair values are calculated based on market prices on similar securities (Level 2). For investment securities where quoted prices or market prices of similar securities are not available, fair values are calculated by using observable and unobservable inputs such as discounted cash flows or other market indicators (Level 3). Investment security valuations are obtained from third-party pricing services. Collateral-Dependent Loans : Collateral-dependent loans are identified for the calculation of the ACL on loans. The fair value used to measure credit loss for this type of loan is commonly based on recent real estate appraisals which are generally obtained at least every 18 months or earlier if there are changes to risk characteristics of the underlying loan. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by independent appraisers to adjust for differences between the comparable sales and income data available. The Company also incorporates an estimate of cost to sell the collateral when the sale is probable. Such adjustments may be significant and result in a Level 3 classification of the inputs for determining fair value. Non-real estate collateral may be valued using an appraisal, net book value based on the borrower’s financial statements or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation and management’s expertise and knowledge of the customer and customer’s business (Level 3). Individually evaluated loans are analyzed for credit loss on a quarterly basis and the ACL on loans is adjusted as required based on the results. Appraisals on collateral-dependent loans are performed by certified general appraisers for commercial properties or certified residential appraisers for residential properties whose qualifications and licenses have been reviewed and verified by the Company. Once received, the Company's internal appraisal department reviews and approves the assumptions and approaches utilized in the appraisal as well as the resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics. Derivative Financial Instruments: The Company obtains broker or dealer quotes to value its interest rate derivative contracts, which use valuation models using observable market data as of the measurement date (Level 2), and incorporates credit valuation adjustments to reflect nonperformance risk in the measurement of fair value (Level 3). Although the Company has determined that the majority of the inputs used to value its interest rate swap derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as borrower risk ratings, to evaluate the likelihood of default by itself and its counterparties. As of March 31, 2024 and December 31, 2023, the Company assessed the significance of the impact of the credit valuation adjustment on the overall valuation of its interest rate swap derivatives and determined the credit valuation adjustment was not significant to the overall valuation of its interest rate swap derivatives. As a result, the Company has classified its interest rate swap derivative valuations in Level 2 of the fair value hierarchy.

Nonrecurring Basis The Company may be required to measure certain financial assets and liabilities at fair value on a nonrecurring basis. These adjustments to fair value usually result from application of lower-of-cost-or-market accounting or write-downs of individual assets. The following tables represent assets measured at fair value on a nonrecurring basis at the dates indicated: Fair Value at March 31, 2024 Total Level 1 Level 2 Level 3 (Dollars in thousands) Collateral-dependent loans: Owner-occupied CRE $ 177 $ — $ — $ 177 Total assets measured at fair value on a nonrecurring basis $ 177 $ — $ — $ 177 Fair Value at December 31, 2023 Total Level 1 Level 2 Level 3 Collateral-dependent loans: Owner-occupied CRE $ 173 $ — $ — $ 173 Total assets measured at fair value on a nonrecurring basis $ 173 $ — $ — $ 173 The following tables present quantitative information about Level 3 fair value measurements for financial instruments measured at fair value on a non-recurring basis at the dates indicated: March 31, 2024 Fair Valuation Unobservable Input(s) Range of Inputs Weighted Average (1) (Dollars in thousands) Collateral-dependent loans $ 177 Market approach Adjustments to reflect current conditions and selling costs 16.5% - 16.5% 16.5% (1) Weighted by net discount to net appraisal fair value December 31, 2023 Fair Valuation Unobservable Input(s) Range of Inputs Weighted Average (1) (Dollars in thousands) Collateral-dependent loans $ 173 Market approach Adjustments to reflect current conditions and selling costs 16.5% - 16.5% 16.5% (1) Weighted by net discount to net appraisal fair value (b) Fair Value of Financial Instruments Broadly traded markets do not exist for most of the Company’s financial instruments; therefore, the fair value calculations attempt to incorporate the effect of current market conditions at a specific time. These determinations are subjective in nature, involve uncertainties and matters of significant judgment and do not include tax ramifications; therefore, the results cannot be determined with precision, substantiated by comparison to independent markets and may not be realized in an actual sale or immediate settlement of the instruments. There may be inherent weaknesses in any calculation technique and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results. For all of these reasons, the aggregation of the fair value calculations presented herein does not represent, and should not be construed to represent, the underlying value of the Company.

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 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 2023 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 three months ended March 31, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. The accompanying Condensed Consolidated Financial Statements presented for the year end December 31, 2023 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. (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 2023 Annual Form 10-K. There have not been any material changes in the Company's significant accounting policies during the three months ended March 31, 2024 from those contained in the 2023 Annual Form 10-K.
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 Company’s instruments indexed to LIBOR were transferred to another index during the year ended December 31, 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. 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 had already applied proportional amortization to its LIHTC investments prior to January 1, 2024. The amendments in this ASU allow the Company to expand the use of proportional amortization to other types of qualifying tax credit investments. The Company has chosen not to expand the use of proportional amortization beyond its LIHTC investment portfolio. Thus, at this time, this ASU only impacts disclosure requirements. FASB ASU 2023-09 , Income Taxes (Topic 740): Improvements to Income Tax Disclosures, was issued in December 2023. The amendments in this ASU require a public business entity to disclose, on an annual basis, a tabular rate reconciliation using both percentages and currency amounts, broken out into specified categories with certain reconciling items further broken out by nature and jurisdiction to the extent those items exceed a specified threshold. In addition, all entities are required to disclose income taxes paid, net of refunds received disaggregated by federal, state/local, and foreign and by jurisdiction if the amount is at least 5% of total income tax payments, net of refunds received. The new standard is effective for annual periods beginning after December 15, 2024, with early adoption permitted. An entity may apply the amendments in this ASU prospectively by providing the revised disclosures for the period ending December 31, 2025 and continuing to provide the pre-ASU disclosures for the prior periods, or may apply the amendments retrospectively by providing the revised disclosures for all periods presented. The Company expects this ASU to only impact its disclosure requirements and 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 Company’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 Company'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 and commercial and multifamily real estate construction and land development 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 March 31, 2024 and December 31, 2023, 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 either March 31, 2024 or December 31, 2023. 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 March 31, 2024 and December 31, 2023. The Company also evaluated investment securities held to maturity for current expected credit losses as of March 31, 2024 and December 31, 2023. There were no investment securities held to maturity classified as nonaccrual or past due as of March 31, 2024 and December 31, 2023, 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 March 31, 2024 and December 31, 2023.
Loans Receivable Credit Quality Indicators	Credit Quality Indicators As part of the on-going monitoring of the credit quality of the Company’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, Oregon and Idaho. The Company 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 2023 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 Company 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 Company 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 pass 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 Company is almost certain of the losses and the outstanding principal balances are generally charged off to the realizable value. There were no loans graded doubtful or loss as of March 31, 2024 and December 31, 2023.
Commitments and Contingencies	Commitments and Contingencies (a) Commitments to Extend Credit In the ordinary course of business, the Company 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 Company 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 Company’s exposure to credit and market risk under commitments to extend credit is represented by the amount of these commitments.
