Accounting Policies [Abstract]
Organization and Significant Accounting Policies	Organization and Significant Accounting Policies Sound Financial Bancorp, a Maryland corporation (“Sound Financial Bancorp”), is the parent holding company for its wholly owned subsidiary, Sound Community Bank (the “Bank”) and the Bank's wholly-owned subsidiary, Sound Community Insurance Agency, Inc. Substantially all of Sound Financial Bancorp's business is conducted through Sound Community Bank, a Washington state-chartered commercial bank. As a Washington commercial bank that is not a member of the Board of Governors of the Federal Reserve System (“Federal Reserve”), the Bank's regulators are the Washington State Department of Financial Institutions (“WDFI”) and the Federal Deposit Insurance Corporation (“FDIC”). As a bank holding company, Sound Financial Bancorp is regulated by the Federal Reserve. Sound Financial Bancorp’s business activities generally are limited to passive investment activities and oversight of its investment in the Bank. Accordingly, the information set forth in this report relates primarily to the Bank. References to the “Company,” “we,” “us,” and “our” mean Sound Financial Bancorp and the Bank unless the context otherwise requires. Subsequent events – The Company has evaluated subsequent events for potential recognition and disclosure. See “Note 21—Subsequent Events” for further information. Basis of Presentation and Use of Estimates – The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for credit losses and the fair value of MSRs. The accompanying consolidated financial statements include the accounts of Sound Financial Bancorp and its wholly-owned subsidiaries, Sound Community Bank and Sound Community Insurance Agency, Inc. All significant intercompany balances and transactions between Sound Financial Bancorp and its subsidiaries have been eliminated in consolidation. Cash and cash equivalents – For purposes of reporting cash flows, cash and cash equivalents include cash on hand and in banks and interest-bearing deposits. All have original maturities of three months or less and may exceed federally insured limits. Investment securities – Investment securities are classified as HTM securities or AFS securities. HTM securities are those securities that the Company has the positive intent and ability to hold until maturity. These securities are carried at amortized cost, adjusted for the amortization or accretion of premiums or discounts. Securities not classified as HTM or trading are considered AFS securities. AFS securities may be sold to implement the Company's asset/liability management strategies and/or in response to changes in interest rates and similar factors. AFS securities are reported at fair value. Dividend and interest income on investment securities are recognized when earned. Unrealized gains and losses, net of the related deferred tax effect, are reported as a net amount in accumulated other comprehensive income (loss) on AFS securities in the Consolidated Balance Sheets. Realized gains and losses on AFS securities, determined using the specific identification method, are included in earnings. Amortization of premiums and accretion of discounts are recognized as adjustments to interest income using the interest method over the period to the earlier of call date or maturity. Allowance for Credit Losses on Investment Securities ( after adoption of ASC 326 ) – The ACL on investment securities is determined for both the HTM and AFS securities in accordance with Accounting Standards Codification (“ASC”) 326 - Financial Instruments - Credit Losses . For AFS securities, we perform a quarterly qualitative evaluation for securities in an unrealized loss position to determine if, for those investments in an unrealized loss position, the decline in fair value is credit related or non-credit related. In determining whether a security’s decline in fair value is credit related, we consider a number of factors including, but not limited to: (i) the extent to which the fair value of the investment is less than its amortized cost; (ii) the financial condition and near-term prospects of the issuer; (iii) downgrades in credit ratings; (iv) payment structure of the security, (v) the ability of the issuer of the security to make scheduled principal and interest payments and (vi) general market conditions, which reflect prospects for the economy as a whole, including interest rates and sector credit spreads. If it is determined that the unrealized loss can be attributed to credit loss, we record the amount of credit loss through a charge to provision for credit losses in current period earnings. However, the amount of credit loss recorded in current period earnings is limited to the amount of the total unrealized loss on the security, which is measured as the amount by which the security’s fair value is below its amortized cost. If we intend to sell, or it is likely we will be required to sell the security in an unrealized loss position, the total amount of the loss is recognized in current period earnings. For unrealized losses deemed non-credit related, we record the loss, net of tax, through accumulated other comprehensive income. For HTM securities, we evaluate at the end of each quarter whether any expected credit losses exist. We determine expected credit losses on AFS and HTM securities through a discounted cash flow approach, using the security’s effective interest rate. However, as previously mentioned, the measurement of credit losses on AFS securities only occurs when, through our qualitative assessment, all or a portion of the unrealized loss is determined to be credit related. Our discounted cash flow approach incorporates assumptions about the collectability of future cash flows. The amount of credit loss is measured as the amount by which the security’s amortized cost exceeds the present value of expected future cash flows. Credit losses on AFS securities are measured on an individual basis, while credit losses on HTM securities are measured on a collective basis according to shared risk characteristics. Credit losses on HTM securities are only recognized at the individual security level when we determine a security no longer possesses risk characteristics similar to other HTM securities in the portfolio. We do not measure credit losses on an investment’s accrued interest receivable, but rather promptly reverse from current period earnings the amount of accrued interest that is no longer deemed collectable. Accrued interest receivable for investment securities is included in accrued interest receivable balances in the Consolidated Balance Sheets. Loans held-for-sale – To mitigate interest-rate sensitivity, from time to time, certain fixed-rate mortgage loans are identified as held-for-sale in the secondary market. Accordingly, such loans are classified as held-for-sale in the Consolidated Balance Sheets and are carried at the lower of cost or estimated fair market value. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. Mortgage loans held-for-sale are generally sold with the mortgage servicing rights retained by the Company. Gains or losses on sales of loans are recognized based on the difference between the selling price and the carrying value of the related loans sold based on the specific identification method. Loans held-for-portfolio – The Company originates mortgage, commercial, and consumer loans to clients. A substantial portion of the loan portfolio is represented by loans secured by real estate located throughout the Puget Sound region, especially King, Snohomish and Pierce Counties, and in Clallam and Jefferson Counties of Washington State. The ability of the Company’s debtors to honor their contracts is dependent upon employment, real estate and general economic conditions in these areas. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balance adjusted for any charge-offs, the ACL, and any premiums, discounts, deferred fees or costs on origination of loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method over the contractual life of the loan for term loans or the straight-line method for open-ended loans. The accrual of interest is discontinued at the time the loan is 90 days past due or if, in management's opinion, the borrower may be unable to meet payment of obligations as they become due, as well as when required by regulatory provisions. Loans are typically charged off no later than 120 days past due, unless secured by collateral. Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not collected for loans that are placed on nonaccrual or charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all of the principal and interest amounts contractually due are brought current, future payments are reasonably assured and payments have been received for six Allowance for Credit Losses on Loans ( after adoption of ASC 326 ) – The ACL is measured using the current expected credit losses (“CECL”) approach for financial instruments measured at amortized cost and other commitments to extend credit. CECL requires the immediate recognition of estimated credit losses expected to occur over the estimated remaining life of the asset. The forward-looking concept of CECL requires loss estimates to consider historical experience, current conditions and reasonable and supportable forecasts. The ACL consists of two elements: (1) identification of loans that do not share risk characteristics with collectively evaluated loan pools are individually analyzed for expected credit loss and (2) establishment of an ACL for collectively evaluated loan pools based upon loans that share similar risk characteristics. We maintain a loan review system that provides a periodic review of the loan portfolio and the identification of individually analyzed loans. For loans that do not share risk characteristics with other loans, expected credit loss is measured on net realizable value that is the difference between the discounted value of the expected future cash flows, based on the original effective interest rate and the amortized cost basis of the loan. For these loans, we recognize expected credit loss equal to the amount by which the net realizable value of the loan is less than the amortized cost basis of the loan (which is net of previous charge-offs and deferred loan fees and costs), except when the loan is collateral dependent, which is when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral (collateral dependent loans). For collateral dependent loans we elected the practical expedient under ASC 326 to estimate expected credit losses based on the fair value of collateral, which considers selling costs in the event sale of the collateral is expected. We estimate the ACL using relevant and reliable information from internal and external sources, related to past events, current conditions, and a reasonable and supportable forecast. The ACL is measured on a collective (segment) basis when similar risk characteristics exist. Historical credit loss experience for both the Company and segment-specific peers provides the basis for the estimate of expected credit losses. Segments are based upon federal call report segmentation. The reserve was applied on a loan-by-loan basis and condensed into the applicable segments reported in “Note 5— Loans.” The ACL is measured on a collective basis for pools of loans with similar risk characteristics. We have identified the following pools of financial assets with similar risk characteristics for measuring expected credit losses: • Construction — While secured by real estate, construction loans represent a greater level of risk than term real estate loans due to the nature of the additional risks associated with not only the completion of construction within an estimated time period and budget, but also the need to sell the building or reach a level of stabilized occupancy sufficient to generate cash flows necessary to support debt service and operating costs. Some loans are originated to a borrower who will occupy the property. There is risk the borrower will not be able to obtain permanent financing upon the completion of construction. We seek to mitigate the additional risks associated with construction lending by requiring borrowers to comply with lower loan-to-value ratios and additional covenants as well as strong financial support of guarantors or borrowers. • One-to-four family residential closed end loans secured by first liens — The most significant drivers of potential loss within our residential real estate portfolio relate to general, regional, or individual changes in economic conditions and their effect on employment and borrowers cash flow. Risk in this portfolio is best measured by changes in borrower credit score and loan-to-value. Loss estimates are based on the general movement in credit score, economic outlook and its effects on employment and the value of homes and historical loss experience adjusted to reflect the economic outlook and the unemployment rate. • One-to-four family residential secured by junior liens — Similar to residential real estate first lien loans, junior liens performance is also primarily driven by borrower cash flows based on employment status. However, junior liens carry additional risks associated with the fact that most of these loans are secured by a deed of trust in a position that is junior to the primary lien holder. Furthermore, for home equity lines of credit (“HELOCs”), there is risk that as the borrower's financial strength deteriorates, the outstanding balance on these credit lines may increase since they may only be canceled by the Company if certain limited criteria are met. For HELOCs, in addition to the ACL maintained as a percent of the outstanding loan balance, we maintain additional reserves for the unfunded portion of the HELOC. • Commercial and multifamily real estate — Non-owner occupied commercial and multifamily properties typically consist of buildings which are leased to others for their use and rely on rents as the primary source of repayment. Owner occupied commercial generally rely on the financial condition of the business operated by the property owner. Property types are predominantly office, retail, light industrial, or multifamily but the portfolio also has some special use properties. As such, the risk of loss associated with these properties is primarily driven by general economic changes or changes in regional economies and the impact of such on a tenant’s or the operating business’ ability to pay. Due to the nature of their use and the greater likelihood of tenant turnover, the management of these properties is more intensive and therefore is more critical to the preclusion of loss. Ultimately this can affect occupancy, rental rates, or both. Additional risk of loss can come from new construction resulting in oversupply, the costs to hold or operate the property, or changes in interest rates. The terms on these loans at origination typically have maturities from five to 10 years with amortization periods from 15 to 25 years. • Commercial and industrial — Repayment of these loans is primarily based on the cash flow of the borrower, and secondarily on the underlying collateral provided by the borrower. A borrower's cash flow may be unpredictable, and collateral securing these loans may fluctuate in value. Most often, collateral includes accounts receivable, inventory, or equipment. Collateral securing these loans may depreciate over time, may be difficult to appraise, may be illiquid and may fluctuate in value based on the success of the business. Actual and forecast changes in gross domestic product are believed to be corollary to losses associated with these loans. • Other consumer loans — These loans are susceptible to three primary risks; non-payment due to income loss, over-extension of credit and, when the borrower is unable to pay, shortfall in collateral value, if any. Typically, non-payment is due to loss of job and will follow general economic trends in the marketplace driven primarily by rises in the unemployment rate. Loss of collateral value can be due to market demand shifts, damage to collateral itself or a combination of those factors. Revolving lines of credit are unsecured and while collection efforts are pursued in the event of default, there is typically limited opportunity for recovery. The ACL quantitative allowance for each segment is measured using a discounted cash flow methodology incorporating a gross historical loss rate. Required cash flows over the contractual life of the loans are the basis for the cash flows utilized in the model, adjusted for defaults, recoveries, and expected prepayments. The contractual term excludes expected extensions, renewals, and modifications. The quantitative analysis utilizes macroeconomic variables to establish a quantitative relationship between economic conditions and loan performance through an economic cycle. Using the historical relationship between economic conditions and loan performance, our expectation of future loan performance is incorporated using an economic forecast based upon unemployment. The forecast is applied over a period that we determined to be reasonable and supportable. Beyond the period over which we can develop or source a reasonable and supportable forecast, the model reverts to long-term average historical loss rates using a straight-line, time-based methodology over the next four quarters. Our current forecast period is four quarters, with a four-quarter reversion period to long-term average historical loss rates. After quantitative considerations, we apply additional qualitative adjustments that consider the expected impact of certain factors not fully captured in the quantitative reserve. The qualitative considerations are constructed within a framework that ranges from zero expected losses (minimum) to a maximum historical loss rate. The maximum historical loss rate is the highest two-year loss rate produced by the base historical loss rate model. Qualitative adjustments include but are not limited to changes in lending policies; changes in nature and volume of the portfolio; change in staff experience level; changes in the volume or trends of classified loans, delinquencies, and nonaccrual; concentration risk; value of underlying collateral; competitive, legal, and regulatory factors; changes in the loan review system; and economic conditions. Management has assigned weightings for each qualitative factor as to the relative importance of that factor to each segment. The qualitative factors are evaluated using a five-point scale ranging from improvement to major risk. Improvement represents an adjustment down to the minimum historical loss rate. Major risk represents an adjustment up to the maximum historical loss rate. The rating of the qualitative factor and the allocated weighting determines the adjustment to the historical loss rate. The ACL is established through the provision for credit losses that is reported in the Consolidated Statements of Income, which is based upon an evaluation of estimated losses in the current loan portfolio, including the evaluation of individually analyzed loans. Charge-offs against the ACL are taken on loans where we determine that the collection of loan principal and interest is unlikely. Recoveries made on loans that have been charged-off are credited to the ACL. Although we believe we have established and maintained the ACL on loans at appropriate levels, changes in reserves may be necessary if actual economic and other conditions differ substantially from the forecast used in estimating the ACL. We evaluate our ACL policy and judgments on an ongoing basis and update them as necessary based on changing conditions. As part of our continuous enhancement to the ACL methodology, during the year ended December 31, 2023, an assessment of the loss rates utilized for each segment was performed and updated to use peer loss rates. Additionally, we enhanced the inputs related to our reasonable and supportable forecast through the inclusion of a quantitative model as part of our forecast which replaced a previous qualitative method. This change in the ACL is considered a change in accounting estimate as per ASC 250-10 provisions, where adjustments should be made prospectively. Accrued interest receivable for loans is reported in accrued interest receivable balances in the Consolidated Balance Sheets. We elected not to measure an ACL for accrued interest receivable and instead elected to reverse interest income on loans that are placed on nonaccrual status, which is generally when the instrument is 90 days past due, or earlier if we believe the collection of interest is doubtful. We concluded that this policy results in the timely reversal of uncollectable interest. Allowance for Credit Losses on Unfunded Commitments (after adoption of ASC 326) – We are required to include unfunded commitments that are expected to be funded in the future within the ACL calculation, other than for those that are unconditionally cancellable. To arrive at that reserve, the reserve percentage for each applicable segment is applied to the unused portion of the expected commitment balance and is multiplied by the expected funding rate. To determine the expected funding rate, we utilize a peer-based historical utilization rate for each segment. The ACL for off-balance-sheet exposures is reported in other liabilities in the Consolidated Balance Sheets. The liability represents an estimate of expected credit losses arising from off-balance-sheet exposures such as unfunded commitments. Modified Loans to Borrowers Experiencing Financial Difficulty – Modified loans are reviewed to determine if the modification was done for borrowers experiencing financial difficulty. Concessions may be granted in various forms, including a reduction in the stated interest rate, reduction in the loan balance or accrued interest, extension of the maturity date, or a combination of these. We refer to these loan modifications to borrowers experiencing financial difficulty as modified loans to troubled borrowers. Such loans are typically placed on nonaccrual status when there is doubt concerning the full repayment of principal and interest or the loan has been past due for a period of 90 days or more. Such loans may be returned to accrual status when all contractual amounts past due have been brought current, and the borrower’s performance under the modified terms of the loan agreement and the ultimate collectability of all contractual amounts due under the modified terms is no longer in doubt. We typically measure the ACL on modified loans to troubled borrowers on an individual basis when the loans are deemed to no longer share risk characteristics that are similar with other loans in the portfolio. Allowance for loan losses ( before adoption of ASC 326 ) – The allowance for loan losses was a reserve established through a provision for loan losses charged to expense and represented management's best estimate of probable incurred losses within the existing loan portfolio as of the balance sheet date. The level of the allowance reflected management's view of trends in loan loss activity, then-current loan portfolio quality and then-present economic, political and regulatory conditions. Portions of the allowance were allocated for specific loans; however, the allowance was available for any loan that was charged off. The allowance was increased by provisions charged to earnings and by recoveries of amounts previously charged off, and was reduced by charge-offs on loans (or portions thereof) deemed to be uncollectible. Loan charge-offs were recognized when management believed the collectability of the principal balance outstanding was unlikely. Full or partial charge-offs on collateral dependent impaired loans were generally recognized when the collateral was deemed to be insufficient to support the carrying value of the loan. The allowance for loan losses was maintained at a level sufficient to provide for probable credit losses based upon evaluating known and inherent risks in the loan portfolio. The allowance was provided based upon management's continuing analysis of the pertinent factors underlying the quality of the loan portfolio. These factors included changes in the size and composition of the loan portfolio, delinquency levels, actual loan loss experience, then-current economic conditions, and detailed analysis of individual loans for which full collectability may not have been assured. The detailed analysis included techniques to estimate the fair value of loan collateral and the existence of potential alternative sources of repayment. The allowance consisted of specific, general and unallocated components. Transfers of financial assets – Transfers of an entire financial asset, or a participating interest in an entire financial asset, are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when: (1) a group of financial assets or a participating interest in an entire financial asset has been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Mortgage servicing rights – MSRs represent the value associated with servicing residential mortgage loans when the mortgage loans have been sold into the secondary market and the related servicing has been retained by the Company. The Company may also purchase MSRs. The value is determined through a discounted cash flow analysis, which uses interest rates, prepayment speeds and delinquency rate assumptions as inputs. The Company measures its mortgage servicing assets at fair value and reports changes in fair value through earnings under the caption fair value adjustment on MSRs in other income in the period in which the change occurs. Changes in the fair values of servicing rights occur primarily due to the collection/realization of expected cash flows, as well as changes in valuation inputs and assumptions. Currently, we do not hedge the effects of changes in fair value of our servicing assets. Premises and equipment – Premises, leasehold improvements and furniture and equipment are carried at cost, less accumulated depreciation and amortization. Furniture and equipment are depreciated using the straight-line method over the estimated useful lives of the assets, which range from 1 to 10 years. The cost of leasehold improvements is amortized using the straight-line method over the terms of the related leases. The cost of premises is amortized using the straight-line method over the estimated useful life of the building, up to 39 years. Management reviews premises, leasehold improvements and furniture and equipment for impairment when factors exist indicating potential impairment. Bank-owned life insurance, net – The carrying amount of BOLI approximates its fair value, and is estimated using the cash surrender value, net of any surrender charges. Federal Home Loan Bank stock – The Company is a member of the FHLB of Des Moines. FHLB stock represents the Company's investment in the FHLB and is carried at cost, which reasonably approximates its fair value. As a member of the FHLB, the Company is required to maintain a minimum level of investment in FHLB stock based on specific percentages of its outstanding mortgages, total assets, or FHLB advances. At December 31, 2023 and 2022, the Company's minimum required investment in FHLB stock was $2.4 million and $2.8 million, respectively. Typically, the Company may request redemption at par value of any stock in excess of the minimum required investment. Stock redemptions are at the discretion of the FHLB. Other real estate owned and repossessed assets – OREO and repossessed assets represent real estate and other assets which the Company has taken control of in partial or full satisfaction of loans. At the time of foreclosure, OREO and repossessed assets are recorded at fair value less estimated costs to sell, which becomes the new basis. Any write-downs based on the asset's fair value at the date of acquisition are charged to the allowance for credit losses. After foreclosure, management periodically performs valuations such that the property is carried at the lower of its new cost basis or fair value, net of estimated costs to sell. Revenue and expenses from operations and subsequent adjustments to the carrying amount of the property are included in other noninterest expense in the Consolidated Statements of Income. In some instances, the Company may make loans to facilitate the sales of OREO. Management reviews all sales for which it is the lending institution. Any gains related to sales of other real estate owned may be deferred until the buyer has a sufficient investment in the property. Leases – We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use assets and operating lease liabilities in our Consolidated Balance Sheets. Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we generally use our incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. The operating lease right-of-use asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Additionally, for equipment leases, we apply a portfolio approach to effectively account for the operating lease right-of-use assets and liabilities. The Company has not entered into leases that meet the definition of a financing lease. Income Taxes – Income taxes are accounted for using the asset and liability method. Under this method a deferred tax asset or liability is determined based on the enacted tax rates which will be in effect when the differences between the financial statement carrying amounts and tax basis of existing assets and liabilities are expected to be reported in the Company's income tax returns. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established to reduce the net carrying amount of deferred tax assets if it is determined to be more likely than not, that all or some portion of the potential deferred tax asset will not be realized. Segment reporting – The Company operates in one segment and makes management decisions based on consolidated results. The Company's operations are solely in the financial services industry and include providing to it

Accounting Standards Update and Change in Accounting Principle [Abstract]
Accounting Pronouncements Recently Issued or Adopted	Accounting Pronouncements Recently Issued or Adopted On 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 guidance for a limited time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this update apply to modifications to eligible contracts (e.g., loans, debt securities, derivatives, borrowings) that replace a reference rate affected by reference rate reform (including rates referenced in fallback provisions) and contemporaneous modifications of other contract terms related to the replacement of the reference rate (including contract modifications to add or change fallback provisions). The following optional expedients for applying the requirements of certain Topics or Industry Subtopics in the related Codification are permitted for contracts that are modified because of reference rate reform and that meet certain scope guidance: 1) Modifications of contracts within the scope of Topics 310, Receivables, and 470, Debt, should be accounted for by prospectively adjusting the effective interest rate; 2) Modifications of contracts within the scope of Topics 840, Leases, and 842, Leases, should be accounted for as a continuation of the existing contracts with no reassessments of the lease classification and the discount rate (for example, the incremental borrowing rate) or remeasurements of lease payments that otherwise would be required under those Topics for modifications not accounted for as separate contracts; and 3) Modifications of contracts do not require an entity to reassess its original conclusion about whether that contract contains an embedded derivative that is clearly and closely related to the economic characteristics and risks of the host contract under Subtopic 815-15, Derivatives and Hedging— Embedded Derivatives. In January 2021, ASU 2021-01 updated amendments in the new ASU to clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The ASU also amends the expedients and exceptions in Topic 848 to capture the incremental consequences of the scope clarification. The amendments in this ASU had differing effective dates, beginning with interim period including and subsequent to March 12, 2020 through December 31, 2022. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and subsequent amendments to the initial guidance in November 2018, ASU No. 2018-19, April 2019, ASU 2019-04, May 2019, ASU 2019-05, November 2019, ASU 2019-11, February 2020, ASU 2020-02, and March 2020, ASU 2020-03, all of which clarify the codification and correct unintended application of the guidance. This ASU replaces the incurred loss impairment methodology that recognizes credit losses when a probable loss has been incurred with new methodology where loss estimates are based upon lifetime expected credit losses. The amendments in this ASU require a financial asset that is measured at amortized cost to be presented at the net amount expected to be collected. The income statement would then reflect the measurement of credit losses for newly recognized financial assets as well as changes to the expected credit losses that have taken place during the reporting period. The Company adopted the provisions of ASC 326 through the application of the modified retrospective transition approach and recorded a net decrease of approximately $1.1 million to the beginning balance of retained earnings as of January 1, 2023 for the cumulative effect adjustment, reflecting an initial adjustment to the ACL of $1.5 million, net of related deferred tax assets arising from temporary differences of $305 thousand, commonly referred to as the “Day 1” adjustment. The Day 1 adjustment to the ACL is reflective of expected lifetime credit losses associated with the composition of financial assets within in the scope of ASC 326 as of January 1, 2023, which is comprised of loans held for investment and off-balance sheet credit exposures at January 1, 2023, as well as management’s expectation of future economic conditions. The following table presents the impact of adopting ASU 2016-13 on January 1, 2023: (dollars in thousands) As Reported Prior to Adopting Impact of ASC 326 ACL - loans Real estate loans: One- to four- family $ 2,126 $ 1,771 $ 355 Home equity 201 132 69 Commercial and multifamily 2,181 2,501 (320) Construction and land 2,568 1,209 1,359 Total real estate loans 7,075 5,613 1,462 Consumer loans: Manufactured homes 282 462 (180) Floating homes 622 456 166 Other consumer 161 324 (163) Total consumer loans 1,065 1,242 (177) Commercial business loans 221 256 (35) Unallocated (3) 488 (491) Total loans 8,359 7,599 760 ACL - unfunded commitments Reserve for unfunded commitments 1,030 335 695 Total $ 9,389 $ 7,934 $ 1,455 In March 2022, the FASB issued ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures . This ASU eliminates the accounting guidance for troubled debt restructured loans (“TDRs”) by creditors while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Additionally, this ASU requires public business entities to disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases. This ASU was effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, upon the Company’s adoption of the amendments in ASU 2016-13, which is commonly referred to as the current expected credit loss methodology. The Company adopted ASU 2022-02 on January 1, 2023 using the prospective transition guidance which allows the entity to continue estimating expected credit losses in accordance with legacy U.S. GAAP for receivables modified in a TDR until the receivables are subsequently modified or settled. Once a legacy TDR is modified after adoption of ASU 2022-02, the prospective transition guidance no longer applies and the impact to the ACL is recognized in earnings in the period of modification. The adoption of this ASU did not have a material impact on the Company’s consolidated results of operations, financial position or cash flows. As a result of the election to adopt this ASU on a prospective basis, the impact in future periods is not expected to be material. 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, Improvements to Income Tax Disclosures . This ASU requires public business entities to annually (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold. This ASU was released in response to stakeholder feedback indicating that the existing income tax disclosures should be enhanced to provide information to better assess how an entity’s operations and related tax risks and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. This ASU’s amendments are effective for public business entities for annual periods beginning after December 15, 2024, with early adoption permitted. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated results of operations, financial position or cash flows.

Cash and Cash Equivalents [Abstract]
Restricted Cash	Restricted Cash Federal Reserve regulations previously required that the Company maintain certain minimum reserve balances either as cash on hand or on deposit with the Federal Reserve Bank, based on a percentage of deposits. In March 2020, the Federal Reserve announced that it would be reducing the reserve requirement for all depository institutions to zero percent effective March 26, 2020; therefore, there was no reserve requirement at December 31, 2023 and 2022.

At December 31, 2023, the securities portfolio consisted of 11 municipal bonds and 12 agency mortgage-backed securities with a total portfolio fair value of $10.1 million. At December 31, 2022, the securities portfolio consisted of one treasury bill security, 11 municipal bonds and 12 agency mortgage-backed securities with a fair value of $12.0 million. At December 31, 2023, there was one security in an unrealized loss position for less than 12 months, and sixteen securities in an unrealized loss position for more than 12 months. At December 31, 2022, there were 16 securities in an unrealized loss position for less than 12 months, and three securities in an unrealized loss position for more than 12 months. For both 2023 and 2022, the unrealized losses were caused by changes in market interest rates or the widening of market spreads subsequent to the initial purchase of these securities, and not related to the underlying credit of the issuers or the underlying collateral. It is expected that these securities will not be settled at a price less than the amortized cost of each investment. The unrealized losses on these investments are not considered credit losses during the years ended December 31, 2023 and 2022, because the decline in fair value is not attributable to credit quality and because we do not intend, and it is not likely that we will be required, to sell these securities before recovery of their amortized cost basis

Premiums resulting from purchased loans totaled $507 thousand on one-to-four family loans, $320 thousand on commercial and multifamily loans, and $146 thousand on commercial business loans as of December 31, 2022. The Company purchased no loans during the year ended December 31, 2023. During the year ended December 31, 2022, the Company purchased $2.6 million of commercial business loan participations with United States Department of Agriculture guarantees.

Federal regulations provide for the classification of lower quality loans and other assets (such as OREO and repossessed assets), debt and equity securities considered as "substandard," "doubtful" or "loss." An asset is considered "substandard" if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. "Substandard" assets include those characterized by the "distinct possibility" that the insured institution will sustain "some loss" if the deficiencies are not corrected. Assets classified as "doubtful" have all of the weaknesses in those classified "substandard," with the added characteristic that the weaknesses present make "collection or liquidation in full," on the basis of currently existing facts, conditions and values, "highly questionable and improbable." Assets classified as "loss" are those considered "uncollectible" and of such little value that their continuance as assets without the establishment of a specific loss reserve is not warranted. Management regularly reviews loans in the portfolio to assess credit quality indicators and to determine appropriate loan classification and grading. The grades for watch and special mention loans are used by the Company to identify and track potential problem loans which do not rise to the levels described for substandard, doubtful, or loss. These are loans which have been criticized and deserve management's close attention based upon known characteristics such as periodic payment delinquency, failure to comply with contractual terms of the loan, or collateral concerns. Loans identified as watch, special mention, substandard, doubtful, or loss are subject to additional problem loan reporting to management every three months. When we classify problem assets as either substandard or doubtful, we may determine that these assets should be individually analyzed if they no longer share common risk characteristics with the rest of the portfolio. When we classify problem assets as a loss, we are required to charge off those assets in the period in which they are deemed uncollectible. Our determination as to the classification of our assets and the amount of our valuation allowances is subject to review by the FDIC (the Bank’s federal regulator) and the WDFI (the Bank’s state banking regulator), which can order the establishment of additional credit loss allowances. Assets which do not currently expose us to sufficient risk to warrant classification as substandard or doubtful but possess weaknesses are required to be designated as special mention. There were no loans classified as doubtful or loss as of December 31, 2023 and 2022.

The Company has granted modifications which can generally be described in the following categories: Principal Forgiveness : A modification in which the principal is reduced. Rate Modification : A modification in which the interest rate is changed. Term Modification : A modification in which the maturity date, timing of payments or frequency of payments is changed. Payment Modification : A modification in which the dollar amount of the payment is changed. Interest only modifications in which a loan is converted to interest only payments for a period of time are included in this category. Combination Modification : Any other type of modification, including the use of multiple categories above. At December 31, 2023, the Company had no commitments to extend additional credit to borrowers owing loan receivables with modified terms. During the year ended December 31, 2023, there was one modified one-to-four family loan to a borrower experiencing financial difficulty. This loan received a term extension for 90 days, with an amortized cost basis of $90 thousand representing 0.03% of the total class of loans. We have no modified loans to troubled borrowers that have subsequently defaulted at December 31, 2023. Troubled debt restructurings. Prior to the adoption of ASU 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures , the Company had granted a variety of concessions to borrowers in the form of loan modifications that were considered TDRs. Loans classified as legacy TDRs totaled $1.7 million and $2.0 million at December 31, 2023 and 2022, respectively. Collateral Dependent Loans . Loans that have been classified as collateral dependent are loans where substantially all repayment of the loan is expected to come from the operation of or eventual liquidation of the collateral. Collateral dependent loans are evaluated individually for purposes of determining the ACL, which is determined based on the estimated fair value of the collateral. Estimates for costs to sell are included in the determination of the ACL when liquidation of the collateral is anticipated. In cases where the loan is well secured and the estimated value of the collateral exceeds the amortized cost of the loan, no ACL is recorded. The following tables summarize collateral dependent loans by collateral type as of the dates indicated (in thousands): December 31, 2023 Commercial Real Estate Residential Real Estate Land Other Residential Total Real estate loans: One- to four- family $ — $ 664 $ — $ 545 $ 1,209 Home equity — 84 — — 84 Total real estate loans — 748 — 545 1,293 Consumer loans: Manufactured homes — — — 228 228 Total consumer loans — — — 228 228 Commercial business loans — — — 2,135 2,135 Total loans $ — $ 748 $ — $ 2,908 $ 3,656 Impaired Loans . Prior to the adoption of ASC 326 on January 1, 2023, we classified loans as impaired when we determined that we might be unable to collect payments of principal or interest when due under the terms of the loan. In the process of identifying loans as impaired, we took into consideration factors which include payment history and status, collateral value, financial condition of the borrower, and the probability of collecting scheduled payments in the future. Minor payment delays and insignificant payment shortfalls typically did not result in a loan being classified as impaired. The significance of payment delays and shortfalls was considered on a case-by-case basis, after taking into consideration the totality of circumstances surrounding the loan and the borrower, including payment history. Impairment was measured on a loan-by-loan basis for all loans in the portfolio. All TDRs were also classified as impaired loans and were included in the loans individually evaluated for impairment in the calculation of the allowance for loan losses. Impaired loans at December 31, 2022, by type of loan were as follows (in thousands): December 31, 2022 Recorded Investment Unpaid Principal Without With Total Related One-to-four family $ 3,758 $ 3,038 $ 708 $ 3,746 $ 102 Home equity 210 142 68 210 5 Construction and land 358 324 34 358 3 Manufactured homes 187 93 94 187 52 Other consumer 343 261 82 343 22 Total $ 4,856 $ 3,858 $ 986 $ 4,844 $ 184 The following table provides the average recorded investment and interest income on impaired loans for the year ended December 31, 2022, by type of loan (in thousands): Year Ended December 31, 2022 Average Interest Income One-to-four family $ 3,628 $ 106 Home equity 216 16 Commercial and multifamily 1,405 — Construction and land 124 20 Manufactured homes 202 15 Floating homes 98 — Other consumer 299 17 Commercial business 69 — Total $ 6,041 $ 174 Related Parties and Regulatory Matters.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company determines the fair values of its financial instruments based on the requirements established in ASC 820 , Fair Value Measurements , which provides a framework for measuring fair value in accordance with U.S. GAAP and requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 defines fair values for financial instruments as the exit price, the price that would be received for an asset or paid to transfer a liability, in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date under current market conditions. The Company’s fair values for financial instruments at December 31, 2023 and 2022 were determined based on these requirements. The following methods and assumptions were used to estimate the fair value of other financial instruments: Cash and cash equivalents - The estimated fair value is equal to the carrying amount. Available-for-sale securities – AFS securities are recorded at fair value based on quoted market prices, if available. If quoted market prices are not available, management utilizes third-party pricing services or broker quotations from dealers in the specific instruments. Level 2 securities include those traded on an active exchange, as well as U.S. government securities. Held-to-maturity securities – The fair value is based on quoted market prices, if available. If quoted market prices are not available, management utilizes third-party pricing services or broker quotations from dealers in the specific instruments. Level 2 securities include those traded on an active exchange, as well as U.S. government securities. Loans held-for-sale - The fair value of fixed-rate one-to-four family loans is based on whole loan forward prices obtained from government sponsored enterprises. At December 31, 2023 and 2022, loans held-for-sale were carried at cost, as no impairment was required. Loans held-for-portfolio - The estimated fair value of loans-held-for portfolio consists of a credit adjustment to reflect the estimated adjustment to the carrying value of the loans due to credit-related factors and a yield adjustment to reflect the estimated adjustment to the carrying value of the loans due to a differential in yield between the portfolio loan yields and estimated current market rate yields on loans with similar characteristics. The estimated fair values of loans held-for-portfolio reflect exit price assumptions. The liquidity premium/discounts are part of the valuation for exit pricing. Mortgage servicing rights –The fair value of MSRs is determined through a discounted cash flow analysis, which uses interest rates, prepayment speeds, discount rates, and delinquency rate assumptions as inputs. Time deposits - The estimated fair value of time deposits is based on the difference between interest costs paid on the Company’s time deposits and current market rates for time deposits with comparable characteristics. Borrowings - The fair value of borrowings are estimated using the contractual cash flows of each debt instrument discounted using the Company’s current incremental borrowing rates for similar types of borrowing arrangements. Subordinated notes - The fair value of subordinated notes is estimated using discounted cash flows based on current lending rates for similar long-term debt instruments with similar terms and remaining time to maturity. A description of the valuation methodologies used for impaired loans and OREO is as follows: Collateral dependent loans - The fair value of collateral dependent loans is based on the current appraised value of the collateral less estimated costs to sell. OREO and repossessed assets – The fair value of OREO and repossessed assets is based on the current appraised value of the collateral less estimated costs to sell. Off-balance sheet financial instruments - The fair value for the off-balance sheet loan commitments is estimated based on fees charged to others to enter into similar agreements taking into account the remaining terms of the agreements and credit standing of the Company’s clients. The estimated fair value of these commitments is not significant. In certain cases, the inputs used to measure fair value may fall into different levels of the hierarchy. In such cases, the lowest level of inputs that is significant to the measurement is used to determine the hierarchy for the entire asset or liability. Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer, which generally coincides with the Company’s quarterly valuation process. There were no transfers between levels during the years ended December 31, 2023 and 2022. The following tables present information about the level in the fair value hierarchy for the Company’s financial assets and liabilities, whether or not recognized or recorded at fair value, as of December 31, 2023 and 2022 (in thousands): December 31, 2023 Fair Value Measurements Using: Carrying Estimated Level 1 Level 2 Level 3 FINANCIAL ASSETS: Cash and cash equivalents $ 49,690 $ 49,690 $ 49,690 $ — $ — AFS securities 8,287 8,287 — 8,287 — HTM securities 2,166 1,787 — 1,787 — Loans held-for-sale 603 603 — 603 — Loans held-for-portfolio, net 885,718 837,579 — — 837,579 MSRs 4,632 4,632 — — 4,632 FINANCIAL LIABILITIES: Time deposits 307,962 308,604 — 308,604 — Borrowings 40,000 40,000 — 40,000 — Subordinated notes 11,717 9,996 — 9,996 — December 31, 2022 Fair Value Measurements Using: Carrying Estimated Level 1 Level 2 Level 3 FINANCIAL ASSETS: Cash and cash equivalents $ 57,836 $ 57,836 $ 57,836 $ — $ — AFS securities 10,207 10,207 — 10,207 — HTM securities 2,199 1,810 — 1,810 — Loans held-for-portfolio, net 858,382 801,153 — — 801,153 MSRs 4,687 4,687 — — 4,687 FINANCIAL LIABILITIES: Time deposits 210,305 209,965 — 209,965 — Borrowings 43,000 43,000 — 43,000 — Subordinated notes 11,676 10,420 — 10,420 — The following tables present the balance of assets measured at fair value on a recurring basis at December 31, 2023 and 2022 (in thousands): Fair Value at December 31, 2023 Description Total Level 1 Level 2 Level 3 Municipal bonds $ 5,528 $ — $ 5,528 $ — Agency mortgage-backed securities 2,759 — 2,759 — MSRs 4,632 — — 4,632 Fair Value at December 31, 2022 Description Total Level 1 Level 2 Level 3 Treasury bills $ 1,594 $ — $ 1,594 $ — Municipal bonds $ 5,421 $ — $ 5,421 $ — Agency mortgage-backed securities 3,192 — 3,192 — MSRs 4,687 — — 4,687 The following table provides a description of the valuation technique, unobservable input, and qualitative information about the unobservable inputs for the Company's assets and liabilities classified as Level 3 and measured at fair value on a recurring basis at December 31, 2023: Financial Valuation Unobservable Input(s) Range MSRs Discounted cash flow Prepayment speed assumption 109%-208% (129%) Discount rate 10.5%-14.5% (12.5%) The following table provides a description of the valuation technique, unobservable input, and qualitative information about the unobservable inputs for the Company's assets and liabilities classified as Level 3 and measured at fair value on a recurring basis at December 31, 2022: Financial Valuation Unobservable Input(s) Range MSRs Discounted cash flow Prepayment speed assumption 119%-461% (132%) Discount rate 10.5%-14.5% (12.5%) Generally, any significant increases in the constant prepayment rate and discount rate utilized in the fair value measurement of the MSRs will result in a negative fair value adjustment (and decrease in the fair value measurement). Conversely, a decrease in the constant prepayment rate and discount rate will result in a positive fair value adjustment (and increase in the fair value measurement). An increase in the weighted average life assumptions will result in a decrease in the constant prepayment rate and conversely, a decrease in the weighted average life will result in an increase of the constant prepayment rate. As a result of the difficulty in observing certain significant valuation inputs affecting our “Level 3” fair value assets, we are required to make judgments regarding these items’ fair values. There were no assets or liabilities (excluding MSRs) measured at fair value using significant unobservable inputs (Level 3) on a recurring basis during the years ended December 31, 2023 and 2022. MSRs are measured at fair value using significant unobservable input (Level 3) on a recurring basis and a reconciliation of this asset can be found in “Note 6—Mortgage Servicing Rights.” The following table presents the balance of assets measured at fair value on a nonrecurring basis (in thousands): Fair Value at December 31, 2023 Description Total Level 1 Level 2 Level 3 OREO and repossessed assets $ 575 $ — $ — $ 575 Collateral-dependent loans 3,656 — — 3,656 Fair Value at December 31, 2022 Description Total Level 1 Level 2 Level 3 OREO and repossessed assets $ 659 $ — $ — $ 659 Impaired loans 4,844 — — 4,844 There were no liabilities carried at fair value, measured on a recurring or nonrecurring basis, at December 31, 2023 and 2022.

Share-Based Payment Arrangement [Abstract]
Employee Benefits	Employee Benefits The Company has a 401(k) retirement plan that allows employees to defer a portion of their salary into the 401(k) plan. The Company matches a portion of employees' salary deferrals. 401(k) plan costs are accrued and funded on a current basis. The Company contributed $249 thousand and $259 thousand to the plan for the years ended December 31, 2023 and 2022, respectively. The Bank maintains a deferred compensation account for the benefit of the chief executive officer, established in 1994 in connection with an incentive plan which is no longer active. The chief executive officer is fully vested in the benefits under this plan as of January 2005. Pursuant to the terms of the plan, payments in an amount equal to the fair market value of the assets in the deferred compensation account shall be made to the chief executive officer (or to the designated beneficiary in the event of death) in 120 equal monthly installments commencing on the last day of the month following the month in which her employment with the Bank is terminated. In the event of the death of the chief executive officer and the designated beneficiary prior to the account being fully paid, the remaining value of the account shall be paid in a lump sum to the beneficiary’s estate. The assets in the deferred compensation account consist of cash, which is held in a certificate of deposit at the Bank and earns interest at market rates. At both December 31, 2023 and 2022, the amount held in the certificate of deposit at the Bank was $113 thousand and $111 thousand, respectively. The Bank maintains a nonqualified deferred compensation plan (the “NQDC Plan”), which became effective on January 1, 2017. The purpose of the NQDC Plan is to provide a select group of management or highly-compensated employees of the Bank with an opportunity to defer the receipt of up to eighty percent (80%) of their annual base salary, bonus, performance-based compensation and any commission income and to assist the Company in attracting, retaining and motivating employees of high caliber and experience. In addition to elective deferrals, the Bank may make discretionary and other contributions to be credited to the account of any or all participants, subject to the vesting requirements set forth in the NQDC Plan. Discretionary contributions by the Bank become 100% vested upon the completion of three years of service from a participant’s effective date of participation in the NQDC Plan (with accelerated vesting upon death, disability or a change in control), while other Bank contributions (including matching contributions) vest at the rate of 20% per year, beginning with the participant’s two-year anniversary of his or her date of hire. During the years ended December 31, 2023, and 2022, the Bank made discretionary contributions to the NQDC Plan of $230 thousand and $205 thousand, respectively. Each participant’s deferred compensation account is credited with an investment return determined as if the account was invested in one or more investment funds. Each participant elects the investment funds in which his or her account shall be deemed to be invested. Distributions of vested account balances are made upon death, disability, separation from service, or a specified in-service date unforeseeable emergency. Distributions shall be made in a single cash payment or, at the election of the participant, in annual installments for a period of up to ten (10) years in the case of a separation from service and in annual installments for a period of up to five (5) years in the case of an in-service distribution. The obligations of the Bank under the NQDC Plan are general unsecured obligations of the Bank to pay deferred compensation in the future to eligible participants in accordance with the terms of the NQDC Plan from the general assets of the Bank, although the Bank may establish a trust to hold amounts which the Bank may use to satisfy NQDC Plan distributions from time to time. Distributions from the NQDC Plan are governed by the Internal Revenue Code and the NQDC Plan. The Company may, at any time, in its sole discretion, terminate the NQDC Plan or amend or modify the NQDC Plan, in whole or in part, except that no such termination, amendment or modification shall have any retroactive effect to reduce any amounts deemed to be accrued and vested prior to such amendment. Supplemental Executive Retirement Plans. The Company maintains two supplemental executive retirement plans for the benefit of the chief executive officer, which are intended to be unfunded, non-contributory defined benefit plans maintained primarily to provide her with supplemental retirement income. The first supplemental executive retirement plan ("SERP 1") was effective as of August 14, 2007. The second supplemental executive retirement plan ("SERP 2") was effective as of December 30, 2011, at which time the benefits under SERP 1 were frozen. Under the terms of SERP 1, as amended, the chief executive officer is entitled to receive $53,320 per year for life commencing on the first day of the month following separation from service (as defined in SERP 1) for any reason from Sound Community Bank, subject to a six-month delay if required by Section 409A of the Internal Revenue Code. No payments will be made under SERP 1 in the event of the chief executive officer’s death and any payments that have commenced will cease upon death. In the event the chief executive officer is involuntarily terminated in connection with a change in control (as defined in SERP 1), the chief executive officer will be entitled to receive the annual benefit described in the first sentence of this paragraph commencing upon such termination, subject to a six-month delay if required by Section 409A of the Internal Revenue Code. Under the terms of SERP 2, as amended, upon the chief executive officer’s termination of employment with Sound Community Bank for any reason other than death, the chief executive officer will be entitled to receive additional retirement benefits each month for life commencing on the first day of the month following separation from service (as defined in SERP 2) from Sound Community Bank, subject to a six-month delay if required by Section 409A of the Internal Revenue Code. The additional retirement benefits will equal the amount payable from the annuity underlying SERP 2, which benefits would equal $99,450 per year as of December 31, 2023. In the event of the chief executive officer’s death prior to the commencement of the additional retirement benefits, the beneficiary will be entitled to a single lump sum payment within 90 days thereafter in an amount equal to the Bank's accrual for her retirement benefit under SERP 2 as of the date of death, or approximately $1.1 million at December 31, 2023. If a change in control occurs (as defined in SERP 2), the chief executive officer will receive full retirement benefit under SERP 2 commencing upon the first day of the month following her separation from service from Sound Community Bank, subject to a six-month delay if required by Section 409A of the Internal Revenue Code. Stock Options and Restricted Stock The Company currently has one active stockholder approved equity incentive plan, the Amended and Restated 2013 Equity Incentive Plan (the “2013 Plan”). The 2013 Plan permits the grant of restricted stock, restricted stock units, stock options, and stock appreciation rights. The equity incentive plan approved by stockholders in 2008 (the "2008 Plan") expired in November 2018 and no further awards may be made under the 2008 Plan; provided, however, all awards outstanding under the 2008 Plan remain outstanding in accordance with their terms. Under the 2013 Plan, 181,750 shares of common stock were approved for awards for stock options and stock appreciation rights and 116,700 shares of common stock were approved for awards for restricted stock and restricted stock units. At December 31, 2023, awards for stock options totaling 295,241 shares and awards for restricted stock totaling 159,066 shares of Company common stock have been granted in the aggregate, net of any forfeitures, under the 2008 Plan and 2013 Plan to participants. As of December 31, 2023, 6,469 awards for stock options and 8,048 awards for restricted stock remained available for issuance. During the years ended December 31, 2023 and 2022, share-based compensation expense totaled $450 thousand and $475 thousand, respectively. Stock Option Awards All stock option awards granted under the 2008 Plan vest in 20 percent annual increments commencing one year from the grant date in accordance with the requirements of the 2008 Plan. All remaining stock option awards granted under the 2008 Plan are fully vested as of December 31, 2023. The stock option awards granted to date under the 2013 Plan provide for immediate vesting of a portion of the award with the balance of the award vesting on the anniversary date of each grant date in equal annual installments over periods of one The following is a summary of the Company's stock option plan award activity during the period ended December 31, 2023 (dollars in thousands, except per share amounts): Shares Weighted-Average Weighted-Average Aggregate Outstanding at January 1, 2023 91,525 $ 27.64 4.65 $ 1,109 Granted 12,425 40.13 Exercised (22,547) 17.51 Forfeited (551) 40.69 Expired (117) 42.27 Outstanding at December 31, 2023 80,735 32.28 5.36 603 Exercisable 59,093 29.68 4.31 574 Expected to vest, assuming a 0% forfeiture rate over the vesting term 80,735 $ 32.28 5.36 $ 603 At December 31, 2023, there was $137 thousand of total unrecognized compensation cost related to non-vested stock options. This cost is expected to be recognized over the remaining weighted-average vesting period of 2.3 years. The total intrinsic value of the shares exercised during the years ended December 31, 2023 and 2022 was $477 thousand and $207 thousand, respectively. The fair value of each option grant is estimated as of the grant date using the Black-Scholes option-pricing model. The fair value of options granted in 2023 and 2022 were determined using the following weighted-average assumptions as of the grant date. Year Ended December 31, 2023 2022 Annual dividend yield 1.69 % 1.59 % Expected volatility 28.15 % 26.48 % Risk-free interest rate 3.60 % 1.64 % Expected term 6.00 years 6.00 years Weighted-average grant date fair value per option granted $ 11.33 $ 9.95 Restricted Stock Awards The fair value of the restricted stock awards is equal to the fair value of the Company's common stock at the date of grant. Compensation expense is recognized over the vesting period of the awards. The restricted stock awards granted under the 2008 Plan vest in 20% annual increments commencing one year from the grant date. The restricted stock awards granted to date under the 2013 Plan provide for immediate vesting of a portion of the award with the balance of the award vesting on the anniversary date of each of the grant date in equal annual installments over periods of one The following is a summary of the Company's non-vested restricted stock awards for the year ended December 31, 2023: Non-vested Shares Shares Weighted-Average Aggregate Non-vested at January 1, 2023 17,879 $ 37.63 Granted 8,850 40.13 Vested (10,007) 37.13 Forfeited (755) 40.30 Non-vested at December 31, 2023 15,967 39.20 $ 39.00 Expected to vest assuming a 0% forfeiture rate over the vesting term 15,967 $ 39.20 $ 39.00 At December 31, 2023, there was $384 thousand of unrecognized compensation cost related to non-vested restricted stock awards. The cost is expected to be recognized over the weighted-average vesting period of 2.2 years. The total fair value of shares vested for the years ended December 31, 2023 and 2022 was $372 thousand and $308 thousand, respectively. The weighted average grant date fair value per share for the years ended December 31, 2023 and 2022 was $40.13 and $42.85, respectively. Employee Stock Ownership Plan The funds to purchase shares in the ESOP come from contributions the Bank makes up to twice a year to the Plan. For the years ended December 31, 2023 and 2022, the ESOP trustee purchased 18,573 shares and 19,438 shares of the Company's common stock for inclusion in the Plan. The number of allocated shares under the ESOP was 169,647 and 155,135 at December 31, 2023 and 2022, respectively. The fair value of the 169,647 shares held by the ESOP trust was $6.6 million at December 31, 2023. ESOP compensation expense included in salaries and benefits was $691 thousand and $820 thousand for the years ended December 31, 2023 and 2022, respectively.

Broker-Dealer [Abstract]
Capital	Capital Sound Financial Bancorp is a bank holding company under the supervision of the Federal Reserve. Bank holding companies are subject to capital adequacy requirements of the Federal Reserve under the Bank Holding Company Act of 1956, as amended, and the regulations of the Federal Reserve, except that, pursuant to the Economic Growth, Regulatory Relief and Consumer Protection Act, effective August 30, 2018, a bank holding company with consolidated assets of less than $3.0 billion is generally not subject to the Federal Reserve’s capital regulations, which parallel the FDIC’s capital regulations.The Bank is a state-chartered, federally insured institution and thereby is subject to the capital requirements established by the FDIC. Failure to meet minimum capital requirements can initiate certain mandatory and, possibly, additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital regulations that involve quantitative measures of its assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Prompt corrective action provisions are not applicable to bank holding companies. At December 31, 2023, according to the most recent notification from the FDIC, the Bank was categorized as "well capitalized" under the regulatory framework for prompt corrective action. There are no conditions or events since the notification that management believes have changed the Bank’s category. As of January 1, 2020, the Bank elected to use the Community Bank Leverage Ratio (“CBLR”) framework as provided for in the Economic Growth, Regulatory Relief and Consumer Protection Act. To be eligible to utilize the CBLR, the Bank must have total consolidated assets of less than $10 billion, off-balance sheet exposures of 25% or less of its total consolidated assets, and trading assets and trading liabilities of 5.0% or less of its total consolidated assets, all as of the end of the most recent quarter. Under the CBLR framework, a bank will generally be considered well-capitalized and to have met the risk-based and leverage capital requirements of the capital regulations if it has a CBLR greater than 9.0%. A bank electing the framework that ceases to meet any qualifying criteria in a future period and that has a leverage ratio greater than 8% will be allowed a grace period of two reporting periods to satisfy the CBLR qualifying criteria or comply with the generally applicable capital requirements. A bank may opt out of the framework at any time, without restriction, by reverting to the generally applicable risk-based capital rule. At December 31, 2023, the Bank’s Tier I capital was $113.7 million and the CBLR was 10.99% and at December 31, 2022, the Bank’s Tier I capital was $107.7 million and the CBLR was 10.83%. For a bank holding company with less than $3.0 billion in assets, the capital guidelines apply on a bank-only basis and the Federal Reserve expects the holding company's subsidiary banks to be well-capitalized under the prompt corrective action regulations. If Sound Financial Bancorp were subject to regulatory guidelines for bank holding companies with $3.0 billion or more in assets, at December 31, 2023, Sound Financial Bancorp would have exceeded all regulatory capital requirements. The estimated CBLR calculated for Sound Financial Bancorp at December 31, 2023 was 9.78% On July 25, 2023, the Company announced that its Board of Directors approved an extension of the Company’s existing stock repurchase program, which was set to expire on July 31, 2023, until January 31, 2024. Under this stock repurchase program, the Company is authorized to repurchase up to $4.0 million of its outstanding shares of common stock from time to time in the open market, based on prevailing market prices, or in privately negotiated transactions. During the years ended December 31, 2023 and 2022, the Company repurchased a total of 58,035 and 46,799 shares of Company common stock at an average price of $36.81 and $37.05 per share pursuant to the Company’s stock repurchase programs, leaving $1 thousand available for future repurchases under the existing program as of December 31, 2023.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies The Company is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its clients. These financial instruments generally represent a commitment to extend credit in the form of loans. The instruments involve, to varying degrees, elements of credit- and interest-rate risk in excess of the amount recognized in the Consolidated Balance Sheets. The Company’s exposure to credit loss, in the event of nonperformance by the other party to the financial instrument for commitments to extend credit, is represented by the contractual notional amount of those instruments. The Company uses the same credit policies in making commitments as it does for on-balance-sheet instruments. Commitments to extend credit are agreements to lend to a client as long as there is no violation of any condition established by the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Because many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. These commitments are not reflected in the consolidated financial statements. The Company evaluates each client's creditworthiness on a case-by-case basis. The amount of collateral obtained, if it is deemed necessary by the Company, is based on management's credit evaluation of the client. Financial instruments containing commitments representing credit risk were as follows at the dates indicated (in thousands): December 31, 2023 2022 Residential mortgage commitments $ 10,465 $ 3,184 Unfunded construction commitments 34,667 65,072 Unused lines of credit 27,245 32,793 Irrevocable letters of credit 277 275 Total loan commitments $ 72,654 $ 101,324 At December 31, 2023, fixed-rate loan commitments totaled $10.5 million and had a weighted-average interest rate of 7.12%. At December 31, 2022, fixed-rate loan commitments totaled $3.2 million and had a weighted-average interest rate of 7.60%. At December 31, 2023 and 2022, the Company had letters of credit issued by the FHLB with a notional amount of $10.0 million and $8.0 million, respectively, in order to secure Washington State Public Funds. In the ordinary course of business, the Company sells loans without recourse that may have to be subsequently repurchased due to defects that occurred during the origination of the loan. The defects are categorized as documentation errors, underwriting errors, early payment defaults, and fraud. When a loan sold to an investor without recourse fails to perform, the investor will typically review the loan file to determine whether defects in the origination process occurred. If a defect is identified, the Company may be required to either repurchase the loan or indemnify the investor for losses sustained. If there are no defects, the Company has no commitment to repurchase the loan. At December 31, 2023 and 2022, the maximum amount of these guarantees totaled $448.9 million and $472.5 million, respectively. These amounts represent the unpaid principal balances of the Company's loans serviced for others' portfolios. There was one loan for $448 thousand repurchased during the year ended December 31, 2023, and no loans were repurchased during the year ended December 31, 2022. The Company pays certain medical, dental, prescription, and vision claims for its employees, on a self-insured basis. The Company has purchased stop-loss insurance to cover claims that exceed stated limits and has recorded estimated reserves for the ultimate costs for both reported claims and claims incurred but not reported, which were not considered significant at December 31, 2023. During the year-ended December 31, 2023, the Company recorded no stop loss medical insurance claims exceeding stated coverage limits and recorded $227 thousand during the year-ended December 31, 2022. At various times, the Company may be the defendant in various legal proceedings arising in connection with its business. It is the opinion of management that the financial position and the results of operations of the Company will not be materially adversely affected by the outcome of any currently pending legal proceedings and that adequate provision has been made in the accompanying Consolidated Balance Sheets.

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Revenue from Contracts with Customers All of the Company's revenue from contracts with customers within the scope of ASC 606— Revenue from Contracts with Customers ("ASC 606") is recognized in noninterest income on the Consolidated Income Statements with the exception of the net loss on OREO and repossessed assets, which is included in noninterest expense on the Consolidated Income Statements. The following table presents the Company's sources of noninterest income for the year ended December 31, 2023 and 2022 (in thousands). Items outside of the scope of ASC 606 are noted as such. Year Ended December 31, 2023 2022 Noninterest income: Service charges and fee income Account maintenance fees $ 280 $ 324 Transaction-based and overdraft service charges 511 446 Debit/ATM interchange fees 1,388 1,394 Credit card interchange fees 111 40 Loan fees (a) 101 119 Other fees (a) 136 45 Total service charges and fee income 2,527 2,368 Earnings on cash surrender value of bank-owned life insurance (a) 1,179 219 Mortgage servicing income (a) 1,179 1,242 Fair value adjustment on MSRs (a) (219) 207 Net gain on sale of loans (a) 340 546 Total noninterest income $ 5,006 $ 4,582 (a) Not within scope of ASC 606 Account maintenance fees and transaction-based and overdraft service charges The Company earns fees from its customers for account maintenance, transaction-based and overdraft services. Account maintenance fees consist primarily of account fees and analyzed account fees charged on deposit accounts monthly.The performance obligation is satisfied and fees are recognized monthly as the service period is completed. Transaction-based fees and overdraft service fees on deposit accounts are charged to deposit customers for specific services provided to the customer, such as non-sufficient funds, overdraft, and wire services. The performance obligation is completed as the transaction occurs and the fees are recognized at the time each specific service is provided to the customer. Debit/ATM and credit card interchange income Debit/ATM interchange income represent fees earned when a debit card issued by the Bank is used for a transaction. The Bank earns interchange fees from debit cardholder transactions through the MasterCard payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the cardholders' account. Certain expenses directly associated with the debit card are recorded on a net basis with the interchange income. The Company utilizes a third-party agency relationship to brand credit cards with fees for originating new accounts paid by the issuing bank. Credit card interchange income represents fees earned when a credit card is issued by the third-party agent. Similar to debit card interchange fees, the Bank earns an interchange fee for each transaction made with Sound Community Bank's branded credit cards. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the cardholders' credit card. Certain expenses and rebates directly related to the credit card interchange contract are recorded net of the interchange income. Net loss on OREO and repossessed assets We record a gain or loss from the sale of other real estate owned when control of the property transfers to the buyer, which generally occurs at the time of an executed deed of trust. When the Bank finances the sale of OREO to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on sale, we adjust the transaction price and related gain or loss on sale if a significant financing component is present. The Company generated income/incurred expenses on OREO properties, net of gain/losses on sale of OREO, of $13 thousand and $0 for the years ended December 31, 2023 and 2022, respectively, included under noninterest expense on the Consolidated Statements of Income.

Accounting Policies [Abstract]
Subsequent events	Subsequent events –
Basis of Presentation and Use of Estimates	Basis of Presentation and Use of Estimates – The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for credit losses and the fair value of MSRs. The accompanying consolidated financial statements include the accounts of Sound Financial Bancorp and its wholly-owned subsidiaries, Sound Community Bank and Sound Community Insurance Agency, Inc. All significant intercompany balances and transactions between Sound Financial Bancorp and its subsidiaries have been eliminated in consolidation.
Cash and cash equivalents	Cash and cash equivalents – For purposes of reporting cash flows, cash and cash equivalents include cash on hand and in banks and interest-bearing deposits. All have original maturities of three months or less and may exceed federally insured limits.
Investment securities	Investment securities – Investment securities are classified as HTM securities or AFS securities. HTM securities are those securities that the Company has the positive intent and ability to hold until maturity. These securities are carried at amortized cost, adjusted for the amortization or accretion of premiums or discounts. Securities not classified as HTM or trading are considered AFS securities. AFS securities may be sold to implement the Company's asset/liability management strategies and/or in response to changes in interest rates and similar factors. AFS securities are reported at fair value. Dividend and interest income on investment securities are recognized when earned. Unrealized gains and losses, net of the related deferred tax effect, are reported as a net amount in accumulated other comprehensive income (loss) on AFS securities in the Consolidated Balance Sheets. Realized gains and losses on AFS securities, determined using the specific identification method, are included in earnings. Amortization of premiums and accretion of discounts are recognized as adjustments to interest income using the interest method over the period to the earlier of call date or maturity.
Allowance for Credit Losses and Modified Loans	Allowance for Credit Losses on Investment Securities ( after adoption of ASC 326 ) – The ACL on investment securities is determined for both the HTM and AFS securities in accordance with Accounting Standards Codification (“ASC”) 326 - Financial Instruments - Credit Losses . For AFS securities, we perform a quarterly qualitative evaluation for securities in an unrealized loss position to determine if, for those investments in an unrealized loss position, the decline in fair value is credit related or non-credit related. In determining whether a security’s decline in fair value is credit related, we consider a number of factors including, but not limited to: (i) the extent to which the fair value of the investment is less than its amortized cost; (ii) the financial condition and near-term prospects of the issuer; (iii) downgrades in credit ratings; (iv) payment structure of the security, (v) the ability of the issuer of the security to make scheduled principal and interest payments and (vi) general market conditions, which reflect prospects for the economy as a whole, including interest rates and sector credit spreads. If it is determined that the unrealized loss can be attributed to credit loss, we record the amount of credit loss through a charge to provision for credit losses in current period earnings. However, the amount of credit loss recorded in current period earnings is limited to the amount of the total unrealized loss on the security, which is measured as the amount by which the security’s fair value is below its amortized cost. If we intend to sell, or it is likely we will be required to sell the security in an unrealized loss position, the total amount of the loss is recognized in current period earnings. For unrealized losses deemed non-credit related, we record the loss, net of tax, through accumulated other comprehensive income. For HTM securities, we evaluate at the end of each quarter whether any expected credit losses exist. We determine expected credit losses on AFS and HTM securities through a discounted cash flow approach, using the security’s effective interest rate. However, as previously mentioned, the measurement of credit losses on AFS securities only occurs when, through our qualitative assessment, all or a portion of the unrealized loss is determined to be credit related. Our discounted cash flow approach incorporates assumptions about the collectability of future cash flows. The amount of credit loss is measured as the amount by which the security’s amortized cost exceeds the present value of expected future cash flows. Credit losses on AFS securities are measured on an individual basis, while credit losses on HTM securities are measured on a collective basis according to shared risk characteristics. Credit losses on HTM securities are only recognized at the individual security level when we determine a security no longer possesses risk characteristics similar to other HTM securities in the portfolio. We do not measure credit losses on an investment’s accrued interest receivable, but rather promptly reverse from current period earnings the amount of accrued interest that is no longer deemed collectable. Accrued interest receivable for investment securities is included in accrued interest receivable balances in the Consolidated Balance Sheets. Allowance for Credit Losses on Loans ( after adoption of ASC 326 ) – The ACL is measured using the current expected credit losses (“CECL”) approach for financial instruments measured at amortized cost and other commitments to extend credit. CECL requires the immediate recognition of estimated credit losses expected to occur over the estimated remaining life of the asset. The forward-looking concept of CECL requires loss estimates to consider historical experience, current conditions and reasonable and supportable forecasts. The ACL consists of two elements: (1) identification of loans that do not share risk characteristics with collectively evaluated loan pools are individually analyzed for expected credit loss and (2) establishment of an ACL for collectively evaluated loan pools based upon loans that share similar risk characteristics. We maintain a loan review system that provides a periodic review of the loan portfolio and the identification of individually analyzed loans. For loans that do not share risk characteristics with other loans, expected credit loss is measured on net realizable value that is the difference between the discounted value of the expected future cash flows, based on the original effective interest rate and the amortized cost basis of the loan. For these loans, we recognize expected credit loss equal to the amount by which the net realizable value of the loan is less than the amortized cost basis of the loan (which is net of previous charge-offs and deferred loan fees and costs), except when the loan is collateral dependent, which is when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral (collateral dependent loans). For collateral dependent loans we elected the practical expedient under ASC 326 to estimate expected credit losses based on the fair value of collateral, which considers selling costs in the event sale of the collateral is expected. We estimate the ACL using relevant and reliable information from internal and external sources, related to past events, current conditions, and a reasonable and supportable forecast. The ACL is measured on a collective (segment) basis when similar risk characteristics exist. Historical credit loss experience for both the Company and segment-specific peers provides the basis for the estimate of expected credit losses. Segments are based upon federal call report segmentation. The reserve was applied on a loan-by-loan basis and condensed into the applicable segments reported in “Note 5— Loans.” The ACL is measured on a collective basis for pools of loans with similar risk characteristics. We have identified the following pools of financial assets with similar risk characteristics for measuring expected credit losses: • Construction — While secured by real estate, construction loans represent a greater level of risk than term real estate loans due to the nature of the additional risks associated with not only the completion of construction within an estimated time period and budget, but also the need to sell the building or reach a level of stabilized occupancy sufficient to generate cash flows necessary to support debt service and operating costs. Some loans are originated to a borrower who will occupy the property. There is risk the borrower will not be able to obtain permanent financing upon the completion of construction. We seek to mitigate the additional risks associated with construction lending by requiring borrowers to comply with lower loan-to-value ratios and additional covenants as well as strong financial support of guarantors or borrowers. • One-to-four family residential closed end loans secured by first liens — The most significant drivers of potential loss within our residential real estate portfolio relate to general, regional, or individual changes in economic conditions and their effect on employment and borrowers cash flow. Risk in this portfolio is best measured by changes in borrower credit score and loan-to-value. Loss estimates are based on the general movement in credit score, economic outlook and its effects on employment and the value of homes and historical loss experience adjusted to reflect the economic outlook and the unemployment rate. • One-to-four family residential secured by junior liens — Similar to residential real estate first lien loans, junior liens performance is also primarily driven by borrower cash flows based on employment status. However, junior liens carry additional risks associated with the fact that most of these loans are secured by a deed of trust in a position that is junior to the primary lien holder. Furthermore, for home equity lines of credit (“HELOCs”), there is risk that as the borrower's financial strength deteriorates, the outstanding balance on these credit lines may increase since they may only be canceled by the Company if certain limited criteria are met. For HELOCs, in addition to the ACL maintained as a percent of the outstanding loan balance, we maintain additional reserves for the unfunded portion of the HELOC. • Commercial and multifamily real estate — Non-owner occupied commercial and multifamily properties typically consist of buildings which are leased to others for their use and rely on rents as the primary source of repayment. Owner occupied commercial generally rely on the financial condition of the business operated by the property owner. Property types are predominantly office, retail, light industrial, or multifamily but the portfolio also has some special use properties. As such, the risk of loss associated with these properties is primarily driven by general economic changes or changes in regional economies and the impact of such on a tenant’s or the operating business’ ability to pay. Due to the nature of their use and the greater likelihood of tenant turnover, the management of these properties is more intensive and therefore is more critical to the preclusion of loss. Ultimately this can affect occupancy, rental rates, or both. Additional risk of loss can come from new construction resulting in oversupply, the costs to hold or operate the property, or changes in interest rates. The terms on these loans at origination typically have maturities from five to 10 years with amortization periods from 15 to 25 years. • Commercial and industrial — Repayment of these loans is primarily based on the cash flow of the borrower, and secondarily on the underlying collateral provided by the borrower. A borrower's cash flow may be unpredictable, and collateral securing these loans may fluctuate in value. Most often, collateral includes accounts receivable, inventory, or equipment. Collateral securing these loans may depreciate over time, may be difficult to appraise, may be illiquid and may fluctuate in value based on the success of the business. Actual and forecast changes in gross domestic product are believed to be corollary to losses associated with these loans. • Other consumer loans — These loans are susceptible to three primary risks; non-payment due to income loss, over-extension of credit and, when the borrower is unable to pay, shortfall in collateral value, if any. Typically, non-payment is due to loss of job and will follow general economic trends in the marketplace driven primarily by rises in the unemployment rate. Loss of collateral value can be due to market demand shifts, damage to collateral itself or a combination of those factors. Revolving lines of credit are unsecured and while collection efforts are pursued in the event of default, there is typically limited opportunity for recovery. The ACL quantitative allowance for each segment is measured using a discounted cash flow methodology incorporating a gross historical loss rate. Required cash flows over the contractual life of the loans are the basis for the cash flows utilized in the model, adjusted for defaults, recoveries, and expected prepayments. The contractual term excludes expected extensions, renewals, and modifications. The quantitative analysis utilizes macroeconomic variables to establish a quantitative relationship between economic conditions and loan performance through an economic cycle. Using the historical relationship between economic conditions and loan performance, our expectation of future loan performance is incorporated using an economic forecast based upon unemployment. The forecast is applied over a period that we determined to be reasonable and supportable. Beyond the period over which we can develop or source a reasonable and supportable forecast, the model reverts to long-term average historical loss rates using a straight-line, time-based methodology over the next four quarters. Our current forecast period is four quarters, with a four-quarter reversion period to long-term average historical loss rates. After quantitative considerations, we apply additional qualitative adjustments that consider the expected impact of certain factors not fully captured in the quantitative reserve. The qualitative considerations are constructed within a framework that ranges from zero expected losses (minimum) to a maximum historical loss rate. The maximum historical loss rate is the highest two-year loss rate produced by the base historical loss rate model. Qualitative adjustments include but are not limited to changes in lending policies; changes in nature and volume of the portfolio; change in staff experience level; changes in the volume or trends of classified loans, delinquencies, and nonaccrual; concentration risk; value of underlying collateral; competitive, legal, and regulatory factors; changes in the loan review system; and economic conditions. Management has assigned weightings for each qualitative factor as to the relative importance of that factor to each segment. The qualitative factors are evaluated using a five-point scale ranging from improvement to major risk. Improvement represents an adjustment down to the minimum historical loss rate. Major risk represents an adjustment up to the maximum historical loss rate. The rating of the qualitative factor and the allocated weighting determines the adjustment to the historical loss rate. The ACL is established through the provision for credit losses that is reported in the Consolidated Statements of Income, which is based upon an evaluation of estimated losses in the current loan portfolio, including the evaluation of individually analyzed loans. Charge-offs against the ACL are taken on loans where we determine that the collection of loan principal and interest is unlikely. Recoveries made on loans that have been charged-off are credited to the ACL. Although we believe we have established and maintained the ACL on loans at appropriate levels, changes in reserves may be necessary if actual economic and other conditions differ substantially from the forecast used in estimating the ACL. We evaluate our ACL policy and judgments on an ongoing basis and update them as necessary based on changing conditions. As part of our continuous enhancement to the ACL methodology, during the year ended December 31, 2023, an assessment of the loss rates utilized for each segment was performed and updated to use peer loss rates. Additionally, we enhanced the inputs related to our reasonable and supportable forecast through the inclusion of a quantitative model as part of our forecast which replaced a previous qualitative method. This change in the ACL is considered a change in accounting estimate as per ASC 250-10 provisions, where adjustments should be made prospectively. Accrued interest receivable for loans is reported in accrued interest receivable balances in the Consolidated Balance Sheets. We elected not to measure an ACL for accrued interest receivable and instead elected to reverse interest income on loans that are placed on nonaccrual status, which is generally when the instrument is 90 days past due, or earlier if we believe the collection of interest is doubtful. We concluded that this policy results in the timely reversal of uncollectable interest. Allowance for Credit Losses on Unfunded Commitments (after adoption of ASC 326) – We are required to include unfunded commitments that are expected to be funded in the future within the ACL calculation, other than for those that are unconditionally cancellable. To arrive at that reserve, the reserve percentage for each applicable segment is applied to the unused portion of the expected commitment balance and is multiplied by the expected funding rate. To determine the expected funding rate, we utilize a peer-based historical utilization rate for each segment. The ACL for off-balance-sheet exposures is reported in other liabilities in the Consolidated Balance Sheets. The liability represents an estimate of expected credit losses arising from off-balance-sheet exposures such as unfunded commitments. Modified Loans to Borrowers Experiencing Financial Difficulty – Modified loans are reviewed to determine if the modification was done for borrowers experiencing financial difficulty. Concessions may be granted in various forms, including a reduction in the stated interest rate, reduction in the loan balance or accrued interest, extension of the maturity date, or a combination of these. We refer to these loan modifications to borrowers experiencing financial difficulty as modified loans to troubled borrowers. Such loans are typically placed on nonaccrual status when there is doubt concerning the full repayment of principal and interest or the loan has been past due for a period of 90 days or more. Such loans may be returned to accrual status when all contractual amounts past due have been brought current, and the borrower’s performance under the modified terms of the loan agreement and the ultimate collectability of all contractual amounts due under the modified terms is no longer in doubt. We typically measure the ACL on modified loans to troubled borrowers on an individual basis when the loans are deemed to no longer share risk characteristics that are similar with other loans in the portfolio. Allowance for loan losses ( before adoption of ASC 326 ) – The allowance for loan losses was a reserve established through a provision for loan losses charged to expense and represented management's best estimate of probable incurred losses within the existing loan portfolio as of the balance sheet date. The level of the allowance reflected management's view of trends in loan loss activity, then-current loan portfolio quality and then-present economic, political and regulatory conditions. Portions of the allowance were allocated for specific loans; however, the allowance was available for any loan that was charged off. The allowance was increased by provisions charged to earnings and by recoveries of amounts previously charged off, and was reduced by charge-offs on loans (or portions thereof) deemed to be uncollectible. Loan charge-offs were recognized when management believed the collectability of the principal balance outstanding was unlikely. Full or partial charge-offs on collateral dependent impaired loans were generally recognized when the collateral was deemed to be insufficient to support the carrying value of the loan.
Loans held-for-sale	Loans held-for-sale – To mitigate interest-rate sensitivity, from time to time, certain fixed-rate mortgage loans are identified as held-for-sale in the secondary market. Accordingly, such loans are classified as held-for-sale in the Consolidated Balance Sheets and are carried at the lower of cost or estimated fair market value. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. Mortgage loans held-for-sale are generally sold with the mortgage servicing rights retained by the Company. Gains or losses on sales of loans are recognized based on the difference between the selling price and the carrying value of the related loans sold based on the specific identification method.
Loans held-for-portfolio	Loans held-for-portfolio – The Company originates mortgage, commercial, and consumer loans to clients. A substantial portion of the loan portfolio is represented by loans secured by real estate located throughout the Puget Sound region, especially King, Snohomish and Pierce Counties, and in Clallam and Jefferson Counties of Washington State. The ability of the Company’s debtors to honor their contracts is dependent upon employment, real estate and general economic conditions in these areas. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balance adjusted for any charge-offs, the ACL, and any premiums, discounts, deferred fees or costs on origination of loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method over the contractual life of the loan for term loans or the straight-line method for open-ended loans. The accrual of interest is discontinued at the time the loan is 90 days past due or if, in management's opinion, the borrower may be unable to meet payment of obligations as they become due, as well as when required by regulatory provisions. Loans are typically charged off no later than 120 days past due, unless secured by collateral. Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not collected for loans that are placed on nonaccrual or charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all of the principal and interest amounts contractually due are brought current, future payments are reasonably assured and payments have been received for six
Transfers of financial assets	Transfers of financial assets – Transfers of an entire financial asset, or a participating interest in an entire financial asset, are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when: (1) a group of financial assets or a participating interest in an entire financial asset has been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Mortgage servicing rights	Mortgage servicing rights – MSRs represent the value associated with servicing residential mortgage loans when the mortgage loans have been sold into the secondary market and the related servicing has been retained by the Company. The Company may also purchase MSRs. The value is determined through a discounted cash flow analysis, which uses interest rates, prepayment speeds and delinquency rate assumptions as inputs. The Company measures its mortgage servicing assets at fair value and reports changes in fair value through earnings under the caption fair value adjustment on MSRs in other income in the period in which the change occurs. Changes in the fair values of servicing rights occur primarily due to the collection/realization of expected cash flows, as well as changes in valuation inputs and assumptions. Currently, we do not hedge the effects of changes in fair value of our servicing assets.
Premises and equipment	Premises and equipment – Premises, leasehold improvements and furniture and equipment are carried at cost, less accumulated depreciation and amortization. Furniture and equipment are depreciated using the straight-line method over the estimated useful lives of the assets, which range from 1 to 10 years. The cost of leasehold improvements is amortized using the straight-line method over the terms of the related leases. The cost of premises is amortized using the straight-line method over the estimated useful life of the building, up to 39 years. Management reviews premises, leasehold improvements and furniture and equipment for impairment when factors exist indicating potential impairment.
Bank-owned life insurance, net	Bank-owned life insurance, net – The carrying amount of BOLI approximates its fair value, and is estimated using the cash surrender value, net of any surrender charges.
Federal Home Loan Bank stock	Federal Home Loan Bank stock
Other real estate owned and repossessed assets	Other real estate owned and repossessed assets – OREO and repossessed assets represent real estate and other assets which the Company has taken control of in partial or full satisfaction of loans. At the time of foreclosure, OREO and repossessed assets are recorded at fair value less estimated costs to sell, which becomes the new basis. Any write-downs based on the asset's fair value at the date of acquisition are charged to the allowance for credit losses. After foreclosure, management periodically performs valuations such that the property is carried at the lower of its new cost basis or fair value, net of estimated costs to sell. Revenue and expenses from operations and subsequent adjustments to the carrying amount of the property are included in other noninterest expense in the Consolidated Statements of Income. In some instances, the Company may make loans to facilitate the sales of OREO. Management reviews all sales for which it is the lending institution. Any gains related to sales of other real estate owned may be deferred until the buyer has a sufficient investment in the property.
Leases	Leases – We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use assets and operating lease liabilities in our Consolidated Balance Sheets. Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we generally use our incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. The operating lease right-of-use asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Additionally, for equipment leases, we apply a portfolio approach to effectively account for the operating lease right-of-use assets and liabilities. The Company has not entered into leases that meet the definition of a financing lease.
Income Taxes	Income Taxes – Income taxes are accounted for using the asset and liability method. Under this method a deferred tax asset or liability is determined based on the enacted tax rates which will be in effect when the differences between the financial statement carrying amounts and tax basis of existing assets and liabilities are expected to be reported in the Company's income tax returns. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established to reduce the net carrying amount of deferred tax assets if it is determined to be more likely than not, that all or some portion of the potential deferred tax asset will not be realized.
Segment reporting	Segment reporting – The Company operates in one segment and makes management decisions based on consolidated results. The Company's operations are solely in the financial services industry and include providing to its clients traditional banking and other financial services.
Off-balance-sheet credit-related financial instruments	Off-balance-sheet credit-related financial instruments – In the normal course of operations, the Company engages in a variety of financial transactions that are not recorded in our financial statements. These transactions involve varying degrees of off-balance sheet credit, interest rate and liquidity risks. These transactions are used primarily to manage customers' requests for funding and take the form of loan commitments, letters of credit and lines of credit. Such financial instruments are recorded when they are funded. The Company also maintains a separate allowance for credit losses for off-balance sheet credit commitments. Management estimates anticipated losses using expected loss factors consistent with those used for the ACL methodology for loans described above, and utilization assumptions based on historical experience. The allowance for credit losses for off-balance sheet credit commitments totaled $193 thousand and $335 thousand at December 31, 2023 and 2022, respectively, and is included in other liabilities on the Consolidated Balance Sheets. Provision for credit losses for off-balance sheet credit commitments is included in provision for credit on the Consolidated Statements of Income.
Advertising costs	Advertising costs
Comprehensive income	Comprehensive income – Accounting principles generally require that recognized revenue, expenses, gains, and losses be included in net income. Certain changes in assets and liabilities, such as unrealized gains and losses on AFS securities, are reported as a separate component of the stockholders’ equity section of the Consolidated Balance Sheets, net of tax. Such items, along with net income, are components of comprehensive income.
Intangible assets	Intangible assets eight
Employee stock ownership plan	Employee stock ownership plan (“ESOP”)
Earnings per common share	Earnings per common share – Earnings per share is computed using the two-class method. Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period, excluding any participating securities. Participating securities include unvested restricted shares. Unvested restricted shares are considered participating securities because holders of these securities receive non-forfeitable dividends at the same rate as the holders of the Company's common stock. Diluted earnings per share is computed by dividing net income available to common stockholders adjusted for reallocation of undistributed earnings of unvested restricted shares by the weighted average number of common shares determined for the basic earnings per share plus the dilutive effect of common stock equivalents using the treasury stock method based on the average market price for the period. Anti-dilutive shares or stock options are excluded from the calculation of diluted earnings per share.
Fair value	Fair value – Fair value is the price that would be received when an asset is sold or a liability is transferred in an orderly transaction between market participants at the measurement date. Fair values of the Company's financial instruments are based on the fair value hierarchy which requires an entity to maximize the use of observable inputs, typically market data obtained from third parties, and minimize the use of unobservable inputs, which reflects its estimates for market assumptions, when measuring fair value. Three levels of valuation inputs are ranked in accordance with the prescribed fair value hierarchy as follows: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2: Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active. Level 3: Assets or liabilities whose significant value drivers are unobservable. In determining the appropriate levels, the Company performs a detailed analysis of the assets and liabilities that are subject to fair value measurements. In certain cases, the inputs used to measure fair value of an asset or liability may fall into different levels of the fair value hierarchy. The level within which the fair value measurement is categorized is based on the lowest level unobservable input that is significant to the fair value measurement in its entirety. Therefore, an item may be classified in Level 3 even though there may be some significant inputs that are readily observable.
Share-Based Compensation	Share-Based Compensation – The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant date fair value of the award. These costs are recognized on a straight-line basis over the vesting period during which an employee is required to provide services in exchange for the award, also known as the requisite service period. The Company uses the Black-Scholes option pricing model to estimate the fair value of stock options granted. When determining the estimated fair value of stock options granted, the Company utilizes various assumptions regarding the expected volatility of the stock price, the risk-free interest rate for periods within the contractual life of the stock option, and the expected dividend yield that the Company expects over the expected life of the options granted. Reductions in compensation expense associated with forfeited options are expensed based on actual forfeiture experience. The Company measures the fair value of the restricted stock using the closing market price of the Company's common stock on the date of grant. The Company expenses the grant date fair value of the Company's stock options and restricted stock with a corresponding increase in equity. When shares are required to be issued under share-based awards, it is typically the Company’s policy to issue new shares of stock.

Accounting Pronouncements Recently Issued or Adopted	Accounting Pronouncements Recently Issued or Adopted On 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 guidance for a limited time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this update apply to modifications to eligible contracts (e.g., loans, debt securities, derivatives, borrowings) that replace a reference rate affected by reference rate reform (including rates referenced in fallback provisions) and contemporaneous modifications of other contract terms related to the replacement of the reference rate (including contract modifications to add or change fallback provisions). The following optional expedients for applying the requirements of certain Topics or Industry Subtopics in the related Codification are permitted for contracts that are modified because of reference rate reform and that meet certain scope guidance: 1) Modifications of contracts within the scope of Topics 310, Receivables, and 470, Debt, should be accounted for by prospectively adjusting the effective interest rate; 2) Modifications of contracts within the scope of Topics 840, Leases, and 842, Leases, should be accounted for as a continuation of the existing contracts with no reassessments of the lease classification and the discount rate (for example, the incremental borrowing rate) or remeasurements of lease payments that otherwise would be required under those Topics for modifications not accounted for as separate contracts; and 3) Modifications of contracts do not require an entity to reassess its original conclusion about whether that contract contains an embedded derivative that is clearly and closely related to the economic characteristics and risks of the host contract under Subtopic 815-15, Derivatives and Hedging— Embedded Derivatives. In January 2021, ASU 2021-01 updated amendments in the new ASU to clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The ASU also amends the expedients and exceptions in Topic 848 to capture the incremental consequences of the scope clarification. The amendments in this ASU had differing effective dates, beginning with interim period including and subsequent to March 12, 2020 through December 31, 2022. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and subsequent amendments to the initial guidance in November 2018, ASU No. 2018-19, April 2019, ASU 2019-04, May 2019, ASU 2019-05, November 2019, ASU 2019-11, February 2020, ASU 2020-02, and March 2020, ASU 2020-03, all of which clarify the codification and correct unintended application of the guidance. This ASU replaces the incurred loss impairment methodology that recognizes credit losses when a probable loss has been incurred with new methodology where loss estimates are based upon lifetime expected credit losses. The amendments in this ASU require a financial asset that is measured at amortized cost to be presented at the net amount expected to be collected. The income statement would then reflect the measurement of credit losses for newly recognized financial assets as well as changes to the expected credit losses that have taken place during the reporting period. The Company adopted the provisions of ASC 326 through the application of the modified retrospective transition approach and recorded a net decrease of approximately $1.1 million to the beginning balance of retained earnings as of January 1, 2023 for the cumulative effect adjustment, reflecting an initial adjustment to the ACL of $1.5 million, net of related deferred tax assets arising from temporary differences of $305 thousand, commonly referred to as the “Day 1” adjustment. The Day 1 adjustment to the ACL is reflective of expected lifetime credit losses associated with the composition of financial assets within in the scope of ASC 326 as of January 1, 2023, which is comprised of loans held for investment and off-balance sheet credit exposures at January 1, 2023, as well as management’s expectation of future economic conditions. The following table presents the impact of adopting ASU 2016-13 on January 1, 2023: (dollars in thousands) As Reported Prior to Adopting Impact of ASC 326 ACL - loans Real estate loans: One- to four- family $ 2,126 $ 1,771 $ 355 Home equity 201 132 69 Commercial and multifamily 2,181 2,501 (320) Construction and land 2,568 1,209 1,359 Total real estate loans 7,075 5,613 1,462 Consumer loans: Manufactured homes 282 462 (180) Floating homes 622 456 166 Other consumer 161 324 (163) Total consumer loans 1,065 1,242 (177) Commercial business loans 221 256 (35) Unallocated (3) 488 (491) Total loans 8,359 7,599 760 ACL - unfunded commitments Reserve for unfunded commitments 1,030 335 695 Total $ 9,389 $ 7,934 $ 1,455 In March 2022, the FASB issued ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures . This ASU eliminates the accounting guidance for troubled debt restructured loans (“TDRs”) by creditors while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Additionally, this ASU requires public business entities to disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases. This ASU was effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, upon the Company’s adoption of the amendments in ASU 2016-13, which is commonly referred to as the current expected credit loss methodology. The Company adopted ASU 2022-02 on January 1, 2023 using the prospective transition guidance which allows the entity to continue estimating expected credit losses in accordance with legacy U.S. GAAP for receivables modified in a TDR until the receivables are subsequently modified or settled. Once a legacy TDR is modified after adoption of ASU 2022-02, the prospective transition guidance no longer applies and the impact to the ACL is recognized in earnings in the period of modification. The adoption of this ASU did not have a material impact on the Company’s consolidated results of operations, financial position or cash flows. As a result of the election to adopt this ASU on a prospective basis, the impact in future periods is not expected to be material. 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, Improvements to Income Tax Disclosures . This ASU requires public business entities to annually (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold. This ASU was released in response to stakeholder feedback indicating that the existing income tax disclosures should be enhanced to provide information to better assess how an entity’s operations and related tax risks and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. This ASU’s amendments are effective for public business entities for annual periods beginning after December 15, 2024, with early adoption permitted. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated results of operations, financial position or cash flows.
Fair Value Measurements	The Company determines the fair values of its financial instruments based on the requirements established in ASC 820 , Fair Value Measurements , which provides a framework for measuring fair value in accordance with U.S. GAAP and requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 defines fair values for financial instruments as the exit price, the price that would be received for an asset or paid to transfer a liability, in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date under current market conditions. The Company’s fair values for financial instruments at December 31, 2023 and 2022 were determined based on these requirements. The following methods and assumptions were used to estimate the fair value of other financial instruments: Cash and cash equivalents - The estimated fair value is equal to the carrying amount. Available-for-sale securities – AFS securities are recorded at fair value based on quoted market prices, if available. If quoted market prices are not available, management utilizes third-party pricing services or broker quotations from dealers in the specific instruments. Level 2 securities include those traded on an active exchange, as well as U.S. government securities. Held-to-maturity securities – The fair value is based on quoted market prices, if available. If quoted market prices are not available, management utilizes third-party pricing services or broker quotations from dealers in the specific instruments. Level 2 securities include those traded on an active exchange, as well as U.S. government securities. Loans held-for-sale - The fair value of fixed-rate one-to-four family loans is based on whole loan forward prices obtained from government sponsored enterprises. At December 31, 2023 and 2022, loans held-for-sale were carried at cost, as no impairment was required. Loans held-for-portfolio - The estimated fair value of loans-held-for portfolio consists of a credit adjustment to reflect the estimated adjustment to the carrying value of the loans due to credit-related factors and a yield adjustment to reflect the estimated adjustment to the carrying value of the loans due to a differential in yield between the portfolio loan yields and estimated current market rate yields on loans with similar characteristics. The estimated fair values of loans held-for-portfolio reflect exit price assumptions. The liquidity premium/discounts are part of the valuation for exit pricing. Mortgage servicing rights –The fair value of MSRs is determined through a discounted cash flow analysis, which uses interest rates, prepayment speeds, discount rates, and delinquency rate assumptions as inputs. Time deposits - The estimated fair value of time deposits is based on the difference between interest costs paid on the Company’s time deposits and current market rates for time deposits with comparable characteristics. Borrowings - The fair value of borrowings are estimated using the contractual cash flows of each debt instrument discounted using the Company’s current incremental borrowing rates for similar types of borrowing arrangements. Subordinated notes - The fair value of subordinated notes is estimated using discounted cash flows based on current lending rates for similar long-term debt instruments with similar terms and remaining time to maturity. A description of the valuation methodologies used for impaired loans and OREO is as follows: Collateral dependent loans - The fair value of collateral dependent loans is based on the current appraised value of the collateral less estimated costs to sell. OREO and repossessed assets – The fair value of OREO and repossessed assets is based on the current appraised value of the collateral less estimated costs to sell. Off-balance sheet financial instruments - The fair value for the off-balance sheet loan commitments is estimated based on fees charged to others to enter into similar agreements taking into account the remaining terms of the agreements and credit standing of the Company’s clients. The estimated fair value of these commitments is not significant. In certain cases, the inputs used to measure fair value may fall into different levels of the hierarchy. In such cases, the lowest level of inputs that is significant to the measurement is used to determine the hierarchy for the entire asset or liability. Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer, which generally coincides with the Company’s quarterly valuation process. There were no transfers between levels during the years ended December 31, 2023 and 2022.
