Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying financial information is unaudited and has been prepared from the consolidated financial statements of Sound Financial Bancorp, Inc., and its wholly owned subsidiaries, Sound Community Bank and Sound Community Insurance Agency, Inc. References in this document to Sound Financial Bancorp refer to Sound Financial Bancorp, Inc. and references to the “Bank” refer to Sound Community Bank. References to “we,” “us,” and “our” or the “Company” refers to Sound Financial Bancorp and its wholly-owned subsidiaries, Sound Community Bank and Sound Community Insurance Agency, Inc., unless the context otherwise requires. These unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission (“SEC”). In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the financial position and results of operations for the periods presented have been included. Certain information and disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. These unaudited financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC on March 14, 2023 (“2022 Form 10-K”). The results for the interim periods are not necessarily indicative of results for a full year or any other future period. Certain amounts in the prior period’s consolidated financial statements have been reclassified to conform to the current presentation. These classifications do not have an impact on previously reported consolidated net income, stockholders’ equity or earnings per share. We have not made any changes in our significant accounting policies from those disclosed in the 2022 Form 10-K, except for the accounting for debt securities, the allowance for credit losses (“ACL”) on loans and unfunded commitments, and loan modifications as described below. Allowance for Credit Losses on Investment Securities . The ACL on investment securities is determined for both the held-to-maturity and available-for-sale classifications of the investment portfolio in accordance with Accounting Standards Codification (“ASC”) 326 - Financial Instruments - Credit Losses . For available-for-sale investment 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 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. We determine expected credit losses on available-for-sale and held-to-maturity securities through a discounted cash flow approach, using the security’s effective interest rate. However, as previously mentioned, the measurement of credit losses on available-for-sale securities only occurs when, through our qualitative assessment, it is determined all or a portion of the unrealized loss is deemed 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 available-for-sale securities are measured on an individual basis, while credit losses on held-to-maturity securities are measured on a collective basis according to shared risk characteristics. Credit losses on held-to-maturity securities are only recognized at the individual security level when we determine a security no longer possesses risk characteristics similar to others 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 Condensed Consolidated Balance Sheets. Allowance for Credit Losses on Loans and Unfunded Loan Commitments. We maintain an ACL on loans and unfunded loan commitments in accordance with ASC 326. ASC 326 requires us to recognize estimates for lifetime credit losses on loans and unfunded loan commitments at the time of origination or acquisition. The recognition of credit losses at origination or acquisition represents our best estimate of lifetime expected credit losses, given the facts and circumstances associated with a particular loan or group of loans with similar risk characteristics. Determining the ACL involves the use of significant management judgement and estimates, which are subject to change based on management’s ongoing assessment of the credit quality of the loan portfolio and changes in economic forecasts used in the model. We use a historical loss rate model when determining estimates for the ACL for our loan portfolio. We also utilize proxy loan data in our ACL model where our own historical data is not sufficiently available. We do not measure credit losses on a loan’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 loans is included in accrued interest receivable balances in the Condensed Consolidated Balance Sheets. Our ACL model forecasts primarily over a two-year time horizon, which we believe is a reasonable and supportable period. Beyond the two-year forecast time horizon, our ACL model reverts to historical long-term average loss rates. The duration of the forecast horizon, the period over which forecasts revert to long-term averages, the economic forecasts that management utilizes, as well as additional internal and external indicators of economic forecasts that management considers, may change over time depending on the nature and composition of our loan portfolio. We utilize a discounted cash flow ACL model for individually analyzed loans using internally derived estimates for prepayments in determining the amount and timing of future contractual cash flows we expect to collect, unless the loan is deemed collateral dependent, which requires measurement of the ACL based on the estimated expected fair value of the underlying collateral, less costs to sell. The estimate of future cash flows also incorporates estimates for contractual amounts we believe may not be collected, which are based on assumptions for our estimated exposure at default. Our estimated exposure at default is determined by the contractual payment schedule and expected payment profile of the loan, incorporating estimates for expected prepayments and future draws on revolving credit facilities. Our ACL methodology for unfunded loan commitments also includes assumptions concerning the probability an unfunded commitment will be drawn upon by the borrower. These assumptions are based on the historical experience of banks in an independent third party database. Expectations of future cash flows are discounted at the loan’s effective interest rate for individually analyzed loans. The effective interest rate represents the contractual rate on the loan, adjusted for any purchase premiums, or discounts, and deferred fees and costs associated with an originated loan. We have made an accounting policy election to adjust the effective interest rate to take into consideration the effects of estimated prepayments. The resulting ACL represents the amount by which the loan’s amortized cost exceeds the net present value of a loan’s discounted cash flows. The ACL is recorded through a charge to provision for credit losses and is reduced by charge-offs, net of recoveries on loans previously charged-off. It is our policy to charge-off loan balances at the time they are not expected to be collected. The historical loss rate model is derived from our loan portfolio credit history, as well as the comparable credit history for peer banks in Washington state. Key loan level attributes and economic drivers in determining the loss rate for loans include unemployment rates, changes to interest rates, changes in credit quality, changes to the consumer price index, and changes in real estate prices. In order to develop reasonable and supportable forecasts of future conditions, we estimate how those forecasts are expected to impact a borrower’s ability to satisfy their obligations to us and the ultimate collectability of future cash flows over the life of a loan. Management periodically evaluates appropriateness of economic scenarios and may decide that a particular economic scenario or a combination of probability-weighted economic scenarios should be used in our ACL model. Our ACL model at March 31, 2023 includes assumptions concerning the rising interest rate environment, ongoing inflationary pressures throughout the U.S. economy, higher energy prices, the potential impact of the ongoing war between Russia and Ukraine, general uncertainty concerning future economic conditions, and the potential for recessionary conditions. It is important to note that our ACL model relies on multiple economic variables, which are used in several economic scenarios. Although no one economic variable can fully demonstrate the sensitivity of the ACL calculation to changes in the economic variables used in the model, we have identified certain economic variables that have significant influence in our model for determining the ACL. These key economic variables include changes in the Washington state unemployment rate, residential real estate prices in the Seattle Metropolitan Statistical Area, and interest rates. Recognizing that forecasts of macroeconomic conditions are inherently uncertain, we believe that the process to consider the available information and associated risks and uncertainties is appropriately governed and that estimates of expected credit losses were reasonable and appropriate upon adoption and for the three months ended March 31, 2023. Our ACL model also includes adjustments for qualitative factors, where appropriate. We recognize that historical information used as the basis for determining future expected credit losses may not always, by itself, provide a sufficient basis for determining future expected credit losses. We therefore consider the need for qualitative adjustments to the ACL on a quarterly basis. Qualitative adjustments may be related to and include, but are not limited to, factors such as: (i) management’s assessment of economic forecasts used in the model and how those forecasts align with management’s overall evaluation of current and expected economic conditions, (ii) organization specific risks such as credit concentrations, collateral specific risks, regulatory risks, and external factors that may ultimately impact credit quality, (iii) potential model limitations such as limitations identified through back-testing, and other limitations associated with factors such as underwriting changes, acquisition of new portfolios, and changes in portfolio segmentation, and (iv) management’s overall assessment of the adequacy of the ACL, including an assessment of model data inputs used to determine the ACL. Qualitative adjustments primarily relate to certain segments of the loan portfolio deemed by management to be of a higher-risk profile or other factors where management believes the quantitative component of our ACL model may not be fully reflective of levels deemed adequate in the judgement of management. Certain qualitative adjustments also relate to heightened uncertainty as to future macroeconomic conditions and the related impact on certain loan segments. Management reviews the need for an appropriate level of qualitative adjustments on a quarterly basis, and as such, the amount and allocation of qualitative adjustments may change in future periods. Modified Loans to Borrowers Experiencing Financial Difficulty . We occasionally modify loans to alleviate temporary difficulties in the borrower’s financial condition and/or constraints on the borrower’s ability to repay the loan, and to minimize our potential losses. We refer to these modifications as modified loans to troubled borrowers. Modifications may include: changes in the amortization terms of the loan, reductions in interest rates, acceptance of interest only payments, and, in very limited cases, reductions to the outstanding loan balance. 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 in default 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. The determination of the ACL for these loans is based on a discounted cash flow approach for loans measured individually, unless the loan is deemed collateral dependent, which requires measurement of the ACL based on the estimated fair value of the underlying collateral, less estimated costs to sell. GAAP requires us to make certain disclosures related to these loans, including certain types of modifications, as well as how such loans have performed since their modifications. Refer to Note 4 – Loans for additional information concerning modified loans to troubled borrowers.

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 ASU No. 2020-04, " Reference Rate Reform" ("Topic 848"). This ASU provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this 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 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 have differing effective dates, beginning with interim periods including and subsequent to March 12, 2020 through December 31, 2022. The Company does not expect the adoption of ASU 2020-04 to have a material impact on its 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 clarifies codification and corrects unintended application of the guidance. This ASU replaces the existing 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 current 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 Allowance for credit losses - 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 Allowance for credit losses - 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 . The 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, the ASU requires public business entities to disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases. 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

Accrued interest receivable on securities totaled $78 thousand and $54 thousand at March 31, 2023 and December 31, 2022, respectively, in the accompanying Condensed Consolidated Balance Sheets. Accrued interest receivable is excluded from the estimate of expected credit losses. The following table summarizes the aggregate fair value and gross unrealized loss by length of time of those investments for which an allowance for credit losses has not been recorded that have been in a continuous unrealized loss position at the dates indicated (in thousands): March 31, 2023 Less Than 12 Months 12 Months or Longer Total Fair Unrealized Fair Unrealized Fair Unrealized Available-for-sale securities Municipal bonds $ 597 $ (203) $ 3,193 $ (778) $ 3,790 $ (981) Agency mortgage-backed securities 456 (14) 2,451 (338) 2,907 (352) Total available-for-sale securities $ 1,053 $ (217) $ 5,644 $ (1,116) $ 6,697 $ (1,333) Held-to-maturity securities Municipal bonds $ — $ — $ 533 $ (171) $ 533 $ (171) Agency mortgage-backed securities — — 1,286 (200) 1,286 (200) Total held-to-maturity securities $ — $ — $ 1,819 $ (371) $ 1,819 $ (371) December 31, 2022 Less Than 12 Months 12 Months or Longer Total Fair Unrealized Fair Unrealized Fair Unrealized Available-for-sale securities Treasury bills $ 1,594 $ (2) $ — $ — $ 1,594 $ (2) Municipal bonds 2,506 (641) 1,246 (388) 3,752 (1,029) Agency mortgage-backed securities 2,666 (314) 292 (86) 2,958 (400) Total $ 6,766 $ (957) $ 1,538 $ (474) $ 8,304 $ (1,431) Held-to-maturity securities Municipal bonds $ 536 $ (169) $ — $ — $ 536 $ (169) Agency mortgage-backed securities 1,274 (219) — — 1,274 (219) Total held-to-maturity securities $ 1,810 $ (388) $ — $ — $ 1,810 $ (388) There was no allowance for credit losses on securities at March 31, 2023 or December 31, 2022. At March 31, 2023, the total securities portfolio consisted of 12 agency mortgage-backed securities and 11 municipal bonds with a total portfolio fair value of $10.4 million. At December 31, 2022, the securities portfolio consisted of one treasury bill security, 11 agency mortgage-backed securities and 12 municipal bonds with a fair value of $10.2 million. At March 31, 2023, there were five securities in an unrealized loss position for less than 12 months, and 13 securities in an unrealized loss position for more than 12 months. Of the five securities in an unrealized loss position for less than 12 months, two securities were classified as HTM. 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. 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. There was no provision for credit losses recognized for investment securities during the three months ended March 31, 2023, 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 .

Loans modified to borrowers experiencing financial difficulty totaled $2.0 million at March 31, 2023. 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. The Company had no commitments to extend additional credit to borrowers owing loan receivables whose terms have been modified at March 31, 2023. During the three months ended March 31, 2023, there was one one-to-four family loan modified to borrowers experiencing financial difficulty that was in current status as of March 31, 2023. 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 loan receivables that have subsequently defaulted at March 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 TDRs totaled $2.0 million at December 31, 2022, and were previously included in impaired loans. 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): March 31, 2023 Residential Real Estate Land Other Residential Total Real estate loans: One- to four- family $ 985 $ — $ 168 $ 1,153 Home equity 138 — — 138 Construction and land — 322 — 322 Total real estate loans 1,123 322 168 1,614 Consumer loans: Manufactured homes — — 134 134 Total consumer loans — — 134 134 Total loans $ 1,123 $ 322 $ 302 $ 1,748 Impaired Loans. Prior to the adoption of ASC 326 on January 1, 2023, we classified loans as impaired when we determined that we may 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 the dates indicated, 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 Commercial and multifamily — — — — — Construction and land 358 324 34 358 3 Manufactured homes 187 93 94 187 52 Floating homes — — — — — Other consumer 343 261 82 343 22 Commercial business — — — — — Total $ 4,856 $ 3,858 $ 986 $ 4,844 $ 184 The following tables present the average recorded investment and interest income recognized on impaired loans for the periods indicated, by loan types (in thousands): Three Months Ended March 31, 2022 Average Interest Income One-to-four family $ 3,762 $ 25 Home equity 221 4 Commercial and multifamily 2,358 29 Construction and land 67 1 Manufactured homes 218 4 Floating homes 247 — Other consumer 227 4 Commercial business 173 1 Total $ 7,273 $ 68 " id="sjs-B4" xml:space="preserve">Loans Loans-held-for portfolio at the dates indicated, excluding loans held-for-sale, were as follows (in thousands): March 31, December 31, Real estate loans: One-to-four family $ 274,687 $ 274,638 Home equity 19,631 19,548 Commercial and multifamily 307,558 313,358 Construction and land 125,983 116,878 Total real estate loans 727,859 724,422 Consumer loans: Manufactured homes 27,904 26,953 Floating homes 73,579 74,443 Other consumer 17,378 17,923 Total consumer loans 118,861 119,319 Commercial business loans 25,192 23,815 Total loans held-for-portfolio 871,912 867,556 Premiums for purchased loans (1) 946 973 Deferred fees, net (2,313) (2,548) Total loans held-for-portfolio, gross 870,545 865,981 Allowance for credit losses — loans (8,532) (7,599) Total loans held-for-portfolio, net $ 862,013 $ 858,382 (1) Includes premiums resulting from purchased loans of $499 thousand related to one-to-four family loans, $310 thousand related to commercial and multifamily loans, and $137 thousand related to commercial business loans as of March 31, 2023.

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. 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. Therefore we may establish a specific allowance in an amount we deem prudent to address those risks. General allowances represent loss allowances which have been established to recognize the inherent risk associated with lending activities for pooled loans with common risk characteristics, but which, unlike specific allowances, have not been specifically allocated to particular problem assets. When an insured institution classifies problem assets as a loss, it is 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 Federal Deposit Insurance Corporation (“FDIC”), the Bank's federal regulator, and, the Washington Department of Financial Institutions, the Bank's state banking regulator, which can order the establishment of additional loss allowances. Assets which do not currently expose us to sufficient risk to warrant classification in one of the aforementioned categories but possess weaknesses are required to be designated as special mention.

Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Loans are placed on nonaccrual once the loan is 90 days past due or sooner 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 modified to borrowers experiencing financial difficulty totaled $2.0 million at March 31, 2023. 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. The Company had no commitments to extend additional credit to borrowers owing loan receivables whose terms have been modified at March 31, 2023. During the three months ended March 31, 2023, there was one one-to-four family loan modified to borrowers experiencing financial difficulty that was in current status as of March 31, 2023. 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 loan receivables that have subsequently defaulted at March 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 TDRs totaled $2.0 million at December 31, 2022, and were previously included in impaired loans. 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): March 31, 2023 Residential Real Estate Land Other Residential Total Real estate loans: One- to four- family $ 985 $ — $ 168 $ 1,153 Home equity 138 — — 138 Construction and land — 322 — 322 Total real estate loans 1,123 322 168 1,614 Consumer loans: Manufactured homes — — 134 134 Total consumer loans — — 134 134 Total loans $ 1,123 $ 322 $ 302 $ 1,748 Impaired Loans. Prior to the adoption of ASC 326 on January 1, 2023, we classified loans as impaired when we determined that we may 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 the dates indicated, 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 Commercial and multifamily — — — — — Construction and land 358 324 34 358 3 Manufactured homes 187 93 94 187 52 Floating homes — — — — — Other consumer 343 261 82 343 22 Commercial business — — — — — Total $ 4,856 $ 3,858 $ 986 $ 4,844 $ 184 The following tables present the average recorded investment and interest income recognized on impaired loans for the periods indicated, by loan types (in thousands): Three Months Ended March 31, 2022 Average Interest Income One-to-four family $ 3,762 $ 25 Home equity 221 4 Commercial and multifamily 2,358 29 Construction and land 67 1 Manufactured homes 218 4 Floating homes 247 — Other consumer 227 4 Commercial business 173 1 Total $ 7,273 $ 68

Fair Value Measurements

Fair Value Measurements	3 Months Ended
	Mar. 31, 2023
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 (“ASC 820”), 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 March 31, 2023 and December 31, 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 – HTM securities are recorded at amortized cost, adjusted for the amortization or accretion of premiums or discounts. 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 - One-to-four family mortgage loans held-for-sale are recorded at the lower of cost or fair value. The fair value of fixed-rate one-to-four family loans is based on whole loan forward prices obtained from government sponsored enterprises. At March 31, 2023 and December 31, 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 mortgage servicing rights is determined through a discounted cash flow analysis, which uses interest rates, prepayment speeds, discount rates, and delinquency rate assumptions as inputs. FHLB stock - The estimated fair value is equal to the par value of the stock. Non-maturity deposits - The estimated fair value is equal to the carrying amount. 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 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. Troubled debt restructurings (prior to adoption of ASU 2022-02) - The fair value of loan modifications that were considered TDRs prior to the adoption of ASU 2022-02 is based on the current appraised value of the collateral less estimated costs to sell, or internally developed models utilizing a calculation of expected discounted cash flows which contain management’s assumptions. 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 Company’s 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 three months ended March 31, 2023 and 2022.

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 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. Different persons in possession of the same facts may reasonably arrive at different conclusions as to the inputs to be applied in valuing these assets and their fair values. Such differences may result in significantly different fair value measurements. There were no assets or liabilities (excluding mortgage servicing rights) measured at fair value using significant unobservable inputs (Level 3) on a recurring basis during the three months ended March 31, 2023 and 2022. Mortgage servicing rights are measured at fair value using a significant unobservable input (Level 3) on a recurring basis - additional information is included in “Note 6—Mortgage Servicing Rights.” The fair value of individually evaluated loans with specific allocations of the ACL based on collateral values and OREO is generally based on recent real estate appraisals and automated valuation models (“AVMs”). These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers for differences between the comparable sales and income data available. Such adjustments are typically deemed significant unobservable inputs used for determining fair value and result in a Level 3 classification. The following tables present the balance of assets measured at fair value on a nonrecurring basis at the dates indicated (in thousands): Fair Value at March 31, 2023 Total Level 1 Level 2 Level 3 OREO and repossessed assets $ 575 $ — $ — $ 575 Collateral dependent loans 1,748 — — 1,748 Fair Value at December 31, 2022 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 both March 31, 2023 and December 31, 2022.

Stock-based Compensation	Stock-based Compensation Stock Options and Restricted Stock The Company currently has one active stockholder approved stock-based compensation 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. As of March 31, 2023, on an adjusted basis, awards for stock options totaling 295,581 shares and awards for restricted stock totaling 159,396 shares of Company common stock have been granted, net of any forfeitures, to participants in the 2013 Plan and the 2008 Plan. Share-based compensation expense was $192 thousand and $203 thousand for the three months ended March 31, 2023 and March 31, 2022, respectively. Stock Option Awards All stock option awards granted under the 2008 Plan vest in 20% annual increments commencing one year from the grant date in accordance with the requirements of the 2008 Plan. 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 award activity during the three months ended March 31, 2023 (dollars in thousands, except per share amounts): Shares Weighted- Weighted-Average Aggregate Outstanding at January 1, 2023 91,525 $ 27.64 4.65 $ 1,109 Granted 12,425 40.13 Exercised (14,353) 17.23 Forfeited (328) 42.02 Expired — — Outstanding at March 31, 2023 89,269 31.00 5.68 647 Exercisable 66,924 28.23 4.61 627 Expected to vest, assuming a 0% forfeiture rate over the vesting term 89,269 $ 31.00 5.68 $ 647 As of March 31, 2023, there was $199 thousand of total unrecognized compensation cost related to non-vested stock options granted under the Plans. The cost is expected to be recognized over the remaining weighted-average vesting period of approximately 2.9 years. The total intrinsic value of the shares exercised during the three months ended March 31, 2023 and 2022 was $327 thousand and $54 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 during the three months ended March 31, 2023 and 2022 were determined using the following weighted-average assumptions as of the grant date. Three Months Ended March 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 There were 12,425 and 12,800 options granted during the three months ended March 31, 2023 and March 31, 2022, respectively. Restricted Stock Awards The fair value of the restricted stock awards is equal to the fair value of the Company's stock at the date of grant. Compensation expense is recognized over the vesting period that the awards are based. 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 dates 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 award activity during the three months ended March 31, 2023: Shares Weighted-Average Aggregate Intrinsic Value Per Share Non-Vested at January 1, 2023 17,879 $ 37.63 Granted 8,850 40.13 Vested (9,962) 37.14 Forfeited (425) 41.95 Non-Vested at March 31, 2023 16,342 39.17 37.01 Expected to vest assuming a 0% forfeiture rate over the vesting term 16,342 $ 39.17 $ 37.01 As of March 31, 2023, there was $594 thousand of unrecognized compensation cost related to non-vested restricted stock granted under the Plans. The cost is expected to be recognized over the weighted-average vesting period of 2.7 years. The total fair value of shares vested for the three months ended March 31, 2023 and 2022 was $370 thousand and $306 thousand, respectively. Employee Stock Ownership Plan The fair value of the 155,135 shares held by the Company’s Employee Stock Ownership Plan (the “ESOP”) trust was $6.1 million at March 31, 2023.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying financial information is unaudited and has been prepared from the consolidated financial statements of Sound Financial Bancorp, Inc., and its wholly owned subsidiaries, Sound Community Bank and Sound Community Insurance Agency, Inc. References in this document to Sound Financial Bancorp refer to Sound Financial Bancorp, Inc. and references to the “Bank” refer to Sound Community Bank. References to “we,” “us,” and “our” or the “Company” refers to Sound Financial Bancorp and its wholly-owned subsidiaries, Sound Community Bank and Sound Community Insurance Agency, Inc., unless the context otherwise requires. These unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission (“SEC”). In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the financial position and results of operations for the periods presented have been included. Certain information and disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. These unaudited financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC on March 14, 2023 (“2022 Form 10-K”). The results for the interim periods are not necessarily indicative of results for a full year or any other future period. Certain amounts in the prior period’s consolidated financial statements have been reclassified to conform to the current presentation. These classifications do not have an impact on previously reported consolidated net income, stockholders’ equity or earnings per share. We have not made any changes in our significant accounting policies from those disclosed in the 2022 Form 10-K, except for the accounting for debt securities, the allowance for credit losses (“ACL”) on loans and unfunded commitments, and loan modifications as described below.
Accounting Pronouncements Recently Issued or Adopted	Accounting Pronouncements Recently Issued or Adopted On March 2020, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2020-04, " Reference Rate Reform" ("Topic 848"). This ASU provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this 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 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 have differing effective dates, beginning with interim periods including and subsequent to March 12, 2020 through December 31, 2022. The Company does not expect the adoption of ASU 2020-04 to have a material impact on its 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 clarifies codification and corrects unintended application of the guidance. This ASU replaces the existing 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 current 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 Allowance for credit losses - 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 Allowance for credit losses - 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 . The 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, the ASU requires public business entities to disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases. 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
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 (“ASC 820”), 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 March 31, 2023 and December 31, 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 – HTM securities are recorded at amortized cost, adjusted for the amortization or accretion of premiums or discounts. 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 - One-to-four family mortgage loans held-for-sale are recorded at the lower of cost or fair value. The fair value of fixed-rate one-to-four family loans is based on whole loan forward prices obtained from government sponsored enterprises. At March 31, 2023 and December 31, 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 mortgage servicing rights is determined through a discounted cash flow analysis, which uses interest rates, prepayment speeds, discount rates, and delinquency rate assumptions as inputs. FHLB stock - The estimated fair value is equal to the par value of the stock. Non-maturity deposits - The estimated fair value is equal to the carrying amount. 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 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. Troubled debt restructurings (prior to adoption of ASU 2022-02) - The fair value of loan modifications that were considered TDRs prior to the adoption of ASU 2022-02 is based on the current appraised value of the collateral less estimated costs to sell, or internally developed models utilizing a calculation of expected discounted cash flows which contain management’s assumptions. 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 Company’s 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 three months ended March 31, 2023 and 2022.
Allowance for Credit Losses and Modified Loans	Allowance for Credit Losses on Investment Securities . The ACL on investment securities is determined for both the held-to-maturity and available-for-sale classifications of the investment portfolio in accordance with Accounting Standards Codification (“ASC”) 326 - Financial Instruments - Credit Losses . For available-for-sale investment 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 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. We determine expected credit losses on available-for-sale and held-to-maturity securities through a discounted cash flow approach, using the security’s effective interest rate. However, as previously mentioned, the measurement of credit losses on available-for-sale securities only occurs when, through our qualitative assessment, it is determined all or a portion of the unrealized loss is deemed 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 available-for-sale securities are measured on an individual basis, while credit losses on held-to-maturity securities are measured on a collective basis according to shared risk characteristics. Credit losses on held-to-maturity securities are only recognized at the individual security level when we determine a security no longer possesses risk characteristics similar to others 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 Condensed Consolidated Balance Sheets. Allowance for Credit Losses on Loans and Unfunded Loan Commitments. We maintain an ACL on loans and unfunded loan commitments in accordance with ASC 326. ASC 326 requires us to recognize estimates for lifetime credit losses on loans and unfunded loan commitments at the time of origination or acquisition. The recognition of credit losses at origination or acquisition represents our best estimate of lifetime expected credit losses, given the facts and circumstances associated with a particular loan or group of loans with similar risk characteristics. Determining the ACL involves the use of significant management judgement and estimates, which are subject to change based on management’s ongoing assessment of the credit quality of the loan portfolio and changes in economic forecasts used in the model. We use a historical loss rate model when determining estimates for the ACL for our loan portfolio. We also utilize proxy loan data in our ACL model where our own historical data is not sufficiently available. We do not measure credit losses on a loan’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 loans is included in accrued interest receivable balances in the Condensed Consolidated Balance Sheets. Our ACL model forecasts primarily over a two-year time horizon, which we believe is a reasonable and supportable period. Beyond the two-year forecast time horizon, our ACL model reverts to historical long-term average loss rates. The duration of the forecast horizon, the period over which forecasts revert to long-term averages, the economic forecasts that management utilizes, as well as additional internal and external indicators of economic forecasts that management considers, may change over time depending on the nature and composition of our loan portfolio. We utilize a discounted cash flow ACL model for individually analyzed loans using internally derived estimates for prepayments in determining the amount and timing of future contractual cash flows we expect to collect, unless the loan is deemed collateral dependent, which requires measurement of the ACL based on the estimated expected fair value of the underlying collateral, less costs to sell. The estimate of future cash flows also incorporates estimates for contractual amounts we believe may not be collected, which are based on assumptions for our estimated exposure at default. Our estimated exposure at default is determined by the contractual payment schedule and expected payment profile of the loan, incorporating estimates for expected prepayments and future draws on revolving credit facilities. Our ACL methodology for unfunded loan commitments also includes assumptions concerning the probability an unfunded commitment will be drawn upon by the borrower. These assumptions are based on the historical experience of banks in an independent third party database. Expectations of future cash flows are discounted at the loan’s effective interest rate for individually analyzed loans. The effective interest rate represents the contractual rate on the loan, adjusted for any purchase premiums, or discounts, and deferred fees and costs associated with an originated loan. We have made an accounting policy election to adjust the effective interest rate to take into consideration the effects of estimated prepayments. The resulting ACL represents the amount by which the loan’s amortized cost exceeds the net present value of a loan’s discounted cash flows. The ACL is recorded through a charge to provision for credit losses and is reduced by charge-offs, net of recoveries on loans previously charged-off. It is our policy to charge-off loan balances at the time they are not expected to be collected. The historical loss rate model is derived from our loan portfolio credit history, as well as the comparable credit history for peer banks in Washington state. Key loan level attributes and economic drivers in determining the loss rate for loans include unemployment rates, changes to interest rates, changes in credit quality, changes to the consumer price index, and changes in real estate prices. In order to develop reasonable and supportable forecasts of future conditions, we estimate how those forecasts are expected to impact a borrower’s ability to satisfy their obligations to us and the ultimate collectability of future cash flows over the life of a loan. Management periodically evaluates appropriateness of economic scenarios and may decide that a particular economic scenario or a combination of probability-weighted economic scenarios should be used in our ACL model. Our ACL model at March 31, 2023 includes assumptions concerning the rising interest rate environment, ongoing inflationary pressures throughout the U.S. economy, higher energy prices, the potential impact of the ongoing war between Russia and Ukraine, general uncertainty concerning future economic conditions, and the potential for recessionary conditions. It is important to note that our ACL model relies on multiple economic variables, which are used in several economic scenarios. Although no one economic variable can fully demonstrate the sensitivity of the ACL calculation to changes in the economic variables used in the model, we have identified certain economic variables that have significant influence in our model for determining the ACL. These key economic variables include changes in the Washington state unemployment rate, residential real estate prices in the Seattle Metropolitan Statistical Area, and interest rates. Recognizing that forecasts of macroeconomic conditions are inherently uncertain, we believe that the process to consider the available information and associated risks and uncertainties is appropriately governed and that estimates of expected credit losses were reasonable and appropriate upon adoption and for the three months ended March 31, 2023. Our ACL model also includes adjustments for qualitative factors, where appropriate. We recognize that historical information used as the basis for determining future expected credit losses may not always, by itself, provide a sufficient basis for determining future expected credit losses. We therefore consider the need for qualitative adjustments to the ACL on a quarterly basis. Qualitative adjustments may be related to and include, but are not limited to, factors such as: (i) management’s assessment of economic forecasts used in the model and how those forecasts align with management’s overall evaluation of current and expected economic conditions, (ii) organization specific risks such as credit concentrations, collateral specific risks, regulatory risks, and external factors that may ultimately impact credit quality, (iii) potential model limitations such as limitations identified through back-testing, and other limitations associated with factors such as underwriting changes, acquisition of new portfolios, and changes in portfolio segmentation, and (iv) management’s overall assessment of the adequacy of the ACL, including an assessment of model data inputs used to determine the ACL. Qualitative adjustments primarily relate to certain segments of the loan portfolio deemed by management to be of a higher-risk profile or other factors where management believes the quantitative component of our ACL model may not be fully reflective of levels deemed adequate in the judgement of management. Certain qualitative adjustments also relate to heightened uncertainty as to future macroeconomic conditions and the related impact on certain loan segments. Management reviews the need for an appropriate level of qualitative adjustments on a quarterly basis, and as such, the amount and allocation of qualitative adjustments may change in future periods. Modified Loans to Borrowers Experiencing Financial Difficulty . We occasionally modify loans to alleviate temporary difficulties in the borrower’s financial condition and/or constraints on the borrower’s ability to repay the loan, and to minimize our potential losses. We refer to these modifications as modified loans to troubled borrowers. Modifications may include: changes in the amortization terms of the loan, reductions in interest rates, acceptance of interest only payments, and, in very limited cases, reductions to the outstanding loan balance. 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 in default 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. The determination of the ACL for these loans is based on a discounted cash flow approach for loans measured individually, unless the loan is deemed collateral dependent, which requires measurement of the ACL based on the estimated fair value of the underlying collateral, less estimated costs to sell. GAAP requires us to make certain disclosures related to these loans, including certain types of modifications, as well as how such loans have performed since their modifications. Refer to Note 4 – Loans for additional information concerning modified loans to troubled borrowers.
