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, 2020, as filed with the SEC on March 30, 2021 (“2020 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.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Accounting Pronouncements Recently Issued or Adopted	Accounting Pronouncements Recently Issued or Adopted The Coronavirus Aid, Relief and Economic Security Act ("CARES Act"), signed into law on March 27, 2020, provides relief from certain accounting and financial reporting requirements under U.S. GAAP. Section 4013 of the CARES Act provides temporary relief from the accounting and reporting requirements for troubled debt restructurings (“TDRs”) under Accounting Standards Codification ("ASC") 310-40 for loan modifications related to the novel coronavirus disease 2019 ("COVID-19") pandemic. In addition, on April 7, 2020, a group of banking agencies issued an interagency statement (“Interagency Statement”) for evaluating whether loan modifications that occur in response to the COVID-19 pandemic are TDRs. The Interagency Statement was originally issued on March 22, 2020, but the banking agencies revised it to address the relationship between their TDR accounting and disclosure guidance and the TDR guidance in Section 4013 of the CARES Act. Section 4013 of the CARES Act permits the suspension of ASC 310-40 for loan modifications that are made by financial institutions in response to the COVID-19 pandemic if (1) the borrower was not more than 30 days past due as of December 31, 2019, and (2) the modifications are related to arrangements that defer or delay the payment of principal or interest, or change the interest rate on the loan. The Interagency Statement indicates that a lender can conclude that a borrower is not experiencing financial difficulty if either (1) short-term (e.g., six months) modifications are made in response to COVID-19, such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant related to loans in which the borrower is less than 30 days past due on its contractual payments at the time a modification program is implemented, or (2) the modification or deferral program is mandated by the federal government or a state government. Accordingly, any loan modification made in response to the COVID-19 pandemic that meets either of these practical expedients would not be considered a TDR. The Company adopted this guidance effective March 27, 2020. On December 27, 2020, the Consolidated Appropriations Act 2021 (“CAA 2021”) was signed into law. Among other purposes, CAA 2021 provides coronavirus emergency response and relief, including extending relief offered under the CARES Act related to restructured loans as a result of COVID-19 through January 1, 2022 or 60 days after the end of the national emergency declared by the President, whichever is earlier. In October 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-08, “ Receivables – Nonrefundable Fees and Other Costs ” (“ASU 2020-08”). ASU 2020-08 clarifies that the Company should reevaluate whether a callable debt security is within the scope of paragraph 310-20-35-33 for each reporting period. ASU 2020-08 is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The adoption of ASU 2018-13 did not have a material impact on the Company's consolidated financial statements. On March 2020, the 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 contract modifications 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 period 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 December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This ASU simplifies the accounting for income taxes by removing the exception to the incremental approach for intra-period tax allocation when there is a loss from continuing operations and income or a gain from other items, removing the requirement to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment, and removing the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The adoption of ASU 2019-12 did not have a material impact on the Company's consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans. This ASU modifies disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. Disclosure requirements removed from FASB Subtopic 715-20 include the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year, the amount and timing of plan assets expected to be returned to the employer, related party disclosures about the amount of future annual benefits covered by insurance and annuity contracts and significant transactions between the employer or related parties and the plan, and, for public entities, the effects of a one-percentage-point change in assumed health care cost trend rates on the aggregate of the service and interest cost components of net periodic benefit costs and benefit obligation for postretirement health care benefits. Disclosure requirements added to FASB Subtopic 715-20 include the weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates, and an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. This ASU is effective for fiscal years ending after December 15, 2020. The adoption of ASU No. 2018-14 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 . 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 change in allowance recognized as a result of adoption will occur through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the ASU is adopted. The new guidance may result in an increase in the allowance for loan losses; however, the Company is still in the process of determining the magnitude of the change and its impact on the Company's consolidated financial statements. The FASB issued ASU No. 2019-10, Financial Instruments - Credit Losses (Topic 326) , delaying implementation of ASU No. 2016-13 for SEC smaller reporting company filers until fiscal years beginning after December 15, 2022. The Bank meets the requirements of a smaller reporting company and will delay implementation of ASU No. 2016-13.

Expected maturities of AFS securities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Investments not due at a single maturity date, primarily mortgage-backed investments, are shown separately.

There were no sales of AFS securities during the three and nine months ended September 30, 2021 or 2020. The following table summarizes the aggregate fair value and gross unrealized loss by length of time of those investments that have been in a continuous unrealized loss position at the dates indicated (in thousands): September 30, 2021 Less Than 12 Months 12 Months or Longer Total Fair Unrealized Fair Unrealized Fair Unrealized Municipal bonds $ 660 $ (6) $ — $ — $ 660 $ (6) Agency mortgage-backed securities 434 (11) — — 434 (11) Total $ 1,094 $ (17) $ — $ — $ 1,094 $ (17) December 31, 2020 Less Than 12 Months 12 Months or Longer Total Fair Unrealized Fair Unrealized Fair Unrealized Agency mortgage-backed securities $ 1,618 $ (6) $ — $ — $ 1,618 $ (6) Total $ 1,618 $ (6) $ — $ — $ 1,618 $ (6) There were no credit losses recognized in earnings related to other than temporary impairments during the three and nine months ended September 30, 2021 or 2020. At September 30, 2021, the securities portfolio consisted of 11 agency mortgage-backed securities and nine municipal bonds with a total portfolio fair value of $7.1 million. At December 31, 2020, the securities portfolio consisted of 16 agency mortgage-backed securities and ten municipal bonds with a fair value of $10.2 million. At September 30, 2021, there were three securities in an unrealized loss position for less than 12 months, and there were no securities in an unrealized loss position for more than 12 months. At December 31, 2020, there were three securities in an unrealized loss position for less than 12 months, and there were no 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. The unrealized losses on these investments are not considered other-than-temporary impairment ("OTTI") as of September 30, 2021, 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 . Deterioration in market and economic conditions related to the COVID-19 pandemic may, however, have an adverse impact on credit quality in the future and result in OTTI charges.

A loan is considered impaired when we determine 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 take 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 do not result in a loan being classified as impaired. The significance of payment delays and shortfalls is 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 is measured on a loan by loan basis for all loans in the portfolio. All TDRs are also classified as impaired loans and are 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): September 30, 2021 Recorded Investment Unpaid Principal Without With Total Related One-to-four family $ 3,901 $ 2,749 $ 1,042 $ 3,791 $ 137 Home equity 226 150 76 226 7 Commercial and multifamily — — — — — Construction and land 256 220 35 255 5 Manufactured homes 201 45 156 201 105 Floating homes 504 504 — 504 — Other consumer 108 — 108 108 27 Commercial business 182 182 — 182 — Total $ 5,378 $ 3,850 $ 1,417 $ 5,267 $ 281 December 31, 2020 Recorded Investment Unpaid Principal Without With Total Related One-to-four family $ 3,791 $ 2,392 $ 1,313 $ 3,705 $ 165 Home equity 293 156 137 293 14 Commercial and multifamily 353 353 — 353 — Construction and land 77 40 37 77 6 Manufactured homes 268 47 218 265 163 Floating homes 518 518 — 518 — Other consumer 114 — 114 114 30 Commercial business 615 615 — 615 — Total $ 6,029 $ 4,121 $ 1,819 $ 5,940 $ 378 The following table presents the average recorded investment and interest income recognized on impaired loans for the periods indicated, by loan types (in thousands): Three Months Ended September 30, 2021 2020 Average Interest Income Average Interest Income One-to-four family $ 3,069 $ 60 $ 6,027 $ 69 Home equity 321 3 336 3 Commercial and multifamily — — 465 16 Construction and land 166 11 315 20 Manufactured homes 225 3 349 5 Floating homes 507 5 405 15 Other consumer 109 1 127 — Commercial business 93 1 1,076 12 Total $ 4,490 $ 84 $ 9,100 $ 140 Nine Months Ended September 30, 2021 2020 Average Interest Income Average Interest Income One-to-four family $ 3,322 $ 118 $ 6,650 $ 208 Home equity 305 11 341 12 Commercial and multifamily 176 — 409 26 Construction and land 121 12 579 21 Manufactured homes 244 12 391 19 Floating homes 511 12 406 23 Other consumer 111 4 134 4 Commercial business 353 1 1,174 12 Total $ 5,143 $ 170 $ 10,084 $ 325 Forgone interest on nonaccrual loans was $89 thousand and $62 thousand for the three months ended September 30, 2021 and 2020, respectively, and $138 thousand and $126 thousand for the nine months ended September 30, 2021 and 2020, respectively. There were no commitments to lend additional funds to borrowers whose loans were classified as nonaccrual or impaired at September 30, 2021 and December 31, 2020. Troubled debt restructurings. TDRs are loans accounted for under ASC 310-40, which have renegotiated loan terms to assist borrowers who are unable to meet the original terms of their loans. Such modifications to loan terms may include a lower interest rate, a reduction in principal, or a longer term to maturity. Once a TDR has performed according to its modified terms for six months and the collection of principal and interest under the revised terms is deemed probable, we remove the TDR from nonperforming status. Loans classified as TDRs totaled $2.6 million and $3.2 million at September 30, 2021 and December 31, 2020, respectively, and are included in impaired loans. The Company has granted, in its TDRs, a variety of concessions to borrowers in the form of loan modifications. The modifications granted can generally be described in the following categories: 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. There were no loans modified as a TDR during the three and nine months ended September 30, 2021. There were two TDRs totaling $484 thousand that were paid off during the nine months ended September 30, 2021. There was one loan totaling $146 thousand modified as a TDR during the three months ended September 30, 2020 and four loans totaling $795 thousand modified as TDRs during the nine months ended September 30, 2020. There were two TDR loan totaling $2.9 million that were paid off during the nine months ended September 30, 2020. There were no post-modification changes for the unpaid principal balance in loans, net of partial charge-offs, that were recorded as a result of the TDRs for the three and nine months ended September 30, 2021 and 2020. There were no loans modified as a TDR for which there was a payment default within the first 12 months of modification during the three and nine months ended September 30, 2021. There was one loan totaling $161 thousand modified as a TDR for which there was a payment default within the first 12 months of modification during the nine months ended September 30, 2020. The Company had no commitments to extend additional credit to borrowers owing receivables whose terms have been modified into TDRs. In March 2020, the Company began offering short-term loan modifications to assist borrowers during the COVID-19 pandemic. The CARES Act, and the Interagency Statement provides that a short-term modification made to a loan in response to COVID-19 which meets certain criteria does not need to be placed on nonaccrual status or accounted for as a TDR pursuant to applicable accounting and regulatory guidance until the earlier of 60 days after the national emergency termination date or January 1, 2022. The majority of these borrowers had resumed making payments as of September 30, 2021, and as of that date, there were six residential loans totaling $933 thousand on deferral status under COVID-19 loan modification forbearance agreements. We continue to monitor these loans through our normal credit risk processes and any request for continuation of relief beyond the initial modification is reassessed at that time to determine if a further modification should be granted and if a downgrade in risk rating is appropriate." id="sjs-B4">Loans The composition of the loans-held-for portfolio at the dates indicated, excluding loans held-for-sale, was as follows (in thousands): September 30, December 31, Real estate loans: One-to-four family $ 194,346 $ 130,657 Home equity 14,012 16,265 Commercial and multifamily 246,794 265,774 Construction and land 81,576 62,752 Total real estate loans 536,728 475,448 Consumer loans: Manufactured homes 21,459 20,941 Floating homes 58,358 39,868 Other consumer 15,732 15,024 Total consumer loans 95,549 75,833 Commercial business loans 36,620 64,217 Total loans held-for-portfolio 668,897 615,498 Deferred fees, net (1,346) (2,135) Total loans held-for-portfolio, gross 667,551 613,363 Allowance for loan losses (6,327) (6,000) Total loans held-for-portfolio, net $ 661,224 $ 607,363 The Company was automatically authorized to participate in the U.S. Small Business Administration (“SBA”) Paycheck Protection Program (“PPP”), as a qualified lender since the inception of the program.

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 establish a specific allowance in an amount we deem prudent to address specific impairments. General allowances represent loss allowances which have been established to recognize the inherent risk associated with lending activities, 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, since our conversion to a Washington-chartered commercial bank, 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.

A loan is considered impaired when we determine 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 take 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 do not result in a loan being classified as impaired. The significance of payment delays and shortfalls is 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 is measured on a loan by loan basis for all loans in the portfolio. All TDRs are also classified as impaired loans and are 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): September 30, 2021 Recorded Investment Unpaid Principal Without With Total Related One-to-four family $ 3,901 $ 2,749 $ 1,042 $ 3,791 $ 137 Home equity 226 150 76 226 7 Commercial and multifamily — — — — — Construction and land 256 220 35 255 5 Manufactured homes 201 45 156 201 105 Floating homes 504 504 — 504 — Other consumer 108 — 108 108 27 Commercial business 182 182 — 182 — Total $ 5,378 $ 3,850 $ 1,417 $ 5,267 $ 281 December 31, 2020 Recorded Investment Unpaid Principal Without With Total Related One-to-four family $ 3,791 $ 2,392 $ 1,313 $ 3,705 $ 165 Home equity 293 156 137 293 14 Commercial and multifamily 353 353 — 353 — Construction and land 77 40 37 77 6 Manufactured homes 268 47 218 265 163 Floating homes 518 518 — 518 — Other consumer 114 — 114 114 30 Commercial business 615 615 — 615 — Total $ 6,029 $ 4,121 $ 1,819 $ 5,940 $ 378 The following table presents the average recorded investment and interest income recognized on impaired loans for the periods indicated, by loan types (in thousands): Three Months Ended September 30, 2021 2020 Average Interest Income Average Interest Income One-to-four family $ 3,069 $ 60 $ 6,027 $ 69 Home equity 321 3 336 3 Commercial and multifamily — — 465 16 Construction and land 166 11 315 20 Manufactured homes 225 3 349 5 Floating homes 507 5 405 15 Other consumer 109 1 127 — Commercial business 93 1 1,076 12 Total $ 4,490 $ 84 $ 9,100 $ 140 Nine Months Ended September 30, 2021 2020 Average Interest Income Average Interest Income One-to-four family $ 3,322 $ 118 $ 6,650 $ 208 Home equity 305 11 341 12 Commercial and multifamily 176 — 409 26 Construction and land 121 12 579 21 Manufactured homes 244 12 391 19 Floating homes 511 12 406 23 Other consumer 111 4 134 4 Commercial business 353 1 1,174 12 Total $ 5,143 $ 170 $ 10,084 $ 325 Forgone interest on nonaccrual loans was $89 thousand and $62 thousand for the three months ended September 30, 2021 and 2020, respectively, and $138 thousand and $126 thousand for the nine months ended September 30, 2021 and 2020, respectively. There were no commitments to lend additional funds to borrowers whose loans were classified as nonaccrual or impaired at September 30, 2021 and December 31, 2020. Troubled debt restructurings. TDRs are loans accounted for under ASC 310-40, which have renegotiated loan terms to assist borrowers who are unable to meet the original terms of their loans. Such modifications to loan terms may include a lower interest rate, a reduction in principal, or a longer term to maturity. Once a TDR has performed according to its modified terms for six months and the collection of principal and interest under the revised terms is deemed probable, we remove the TDR from nonperforming status. Loans classified as TDRs totaled $2.6 million and $3.2 million at September 30, 2021 and December 31, 2020, respectively, and are included in impaired loans. The Company has granted, in its TDRs, a variety of concessions to borrowers in the form of loan modifications. The modifications granted can generally be described in the following categories: 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. There were no loans modified as a TDR during the three and nine months ended September 30, 2021. There were two TDRs totaling $484 thousand that were paid off during the nine months ended September 30, 2021. There was one loan totaling $146 thousand modified as a TDR during the three months ended September 30, 2020 and four loans totaling $795 thousand modified as TDRs during the nine months ended September 30, 2020. There were two TDR loan totaling $2.9 million that were paid off during the nine months ended September 30, 2020. There were no post-modification changes for the unpaid principal balance in loans, net of partial charge-offs, that were recorded as a result of the TDRs for the three and nine months ended September 30, 2021 and 2020. There were no loans modified as a TDR for which there was a payment default within the first 12 months of modification during the three and nine months ended September 30, 2021. There was one loan totaling $161 thousand modified as a TDR for which there was a payment default within the first 12 months of modification during the nine months ended September 30, 2020. The Company had no commitments to extend additional credit to borrowers owing receivables whose terms have been modified into TDRs. In March 2020, the Company began offering short-term loan modifications to assist borrowers during the COVID-19 pandemic. The CARES Act, and the Interagency Statement provides that a short-term modification made to a loan in response to COVID-19 which meets certain criteria does not need to be placed on nonaccrual status or accounted for as a TDR pursuant to applicable accounting and regulatory guidance until the earlier of 60 days after the national emergency termination date or January 1, 2022. The majority of these borrowers had resumed making payments as of September 30, 2021, and as of that date, there were six residential loans totaling $933 thousand on deferral status under COVID-19 loan modification forbearance agreements. We continue to monitor these loans through our normal credit risk processes and any request for continuation of relief beyond the initial modification is reassessed at that time to determine if a further modification should be granted and if a downgrade in risk rating is appropriate.

Fair Value Measurements

Fair Value Measurements	9 Months Ended

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 September 30, 2021 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 – Available-for-sale 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. 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 September 30, 2021 and December 31, 2020, 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 Debt - The fair value of subordinated debt 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: Impaired Loans - The fair value of collateral dependent loans 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 and nine months ended September 30, 2021 and 2020. 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 the dates indicated (in thousands): September 30, 2021 Fair Value Measurements Using: Carrying Estimated Level 1 Level 2 Level 3 FINANCIAL ASSETS: Cash and cash equivalents $ 206,702 $ 206,702 $ 206,702 $ — $ — Available-for-sale securities 7,060 7,060 — 7,060 — Loans held-for-sale 3,884 3,884 — 3,884 — Loans held-for-portfolio, net 661,224 658,604 — — 658,604 Mortgage servicing rights 4,211 4,211 — — 4,211 FHLB stock 1,052 1,052 — 1,052 — FINANCIAL LIABILITIES: Non-maturity deposits 688,212 688,212 — 688,212 — Time deposits 119,441 120,798 — 120,798 — Subordinated notes 11,623 11,623 — 11,623 — December 31, 2020 Fair Value Measurements Using: Carrying Estimated Level 1 Level 2 Level 3 FINANCIAL ASSETS: Cash and cash equivalents $ 193,828 $ 193,828 $ 193,828 $ — $ — Available-for-sale securities 10,218 10,218 — 10,218 — Loans held-for-sale 11,604 11,604 — 11,604 — Loans held-for-portfolio, net 607,363 608,575 — — 608,575 Mortgage servicing rights 3,780 3,780 — — 3,780 FHLB stock 877 877 — 877 — FINANCIAL LIABILITIES: Non-maturity deposits 512,508 512,508 — 512,508 — Time deposits 235,473 238,629 — 238,629 — Subordinated notes 11,592 11,592 — 11,592 — The following tables present the balance of assets measured at fair value on a recurring basis as of the dates indicated (in thousands): Fair Value at September 30, 2021 Description Total Level 1 Level 2 Level 3 Municipal bonds 4,370 — 4,370 — Agency mortgage-backed securities 2,690 — 2,690 — Mortgage servicing rights 4,211 — — 4,211 Fair Value at December 31, 2020 Description Total Level 1 Level 2 Level 3 Municipal bonds $ 5,413 $ — $ 5,413 $ — Agency mortgage-backed securities 4,805 — 4,805 — Mortgage servicing rights 3,780 — — 3,780 The following tables provide 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 as of the dates indicated: September 30, 2021 Financial Instrument Valuation Technique Unobservable Input(s) Range Mortgage Servicing Rights Discounted cash flow Prepayment speed assumption 214%-503% (217%) Discount rate 10.5%-14.5% (12.5%) December 31, 2020 Financial Instrument Valuation Technique Unobservable Input(s) Range Mortgage Servicing Rights Discounted cash flow Prepayment speed assumption 178%-276% (247%) Discount rate 10%-12% (10%) Generally, any significant increases in the constant prepayment rate and discount rate utilized in the fair value measurement of the mortgage servicing rights 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. 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 and nine months ended September 30, 2021 and 2020.

Earnings Per Share [Abstract]
Earnings Per Common Share	Earnings Per Common Share Basic earnings per common share is computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding for the period, reduced for average unallocated ESOP shares and average unvested restricted stock awards. Unvested share-based awards containing non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and are included in the computation of earnings per share. Diluted earnings per common share reflect the potential dilution that could occur if securities or other contracts to issue common stock (such as stock awards and options) were exercised or converted to common stock or resulted in the issuance of common stock that then shared in the Company’s earnings. Diluted earnings per common share is computed by dividing net income by the weighted-average number of common shares outstanding for the period increased for the dilutive effect of unexercised stock options and unvested restricted stock awards. The dilutive effect of the unexercised stock options and unvested restricted stock awards is calculated under the treasury stock method utilizing the average market value of the Company's stock for the period.

Share-based Payment Arrangement [Abstract]
Stock-based Compensation	Stock-based Compensation Stock Options and Restricted Stock The Company currently has one active shareholder 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 September 30, 2021, on an adjusted basis, awards for stock options totaling 271,874 shares and awards for restricted stock totaling 142,201 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 $65 thousand and $295 thousand for the three and nine months ended months ended September 30, 2021, respectively, and was $52 thousand and $283 thousand for the three and nine months ended September 30, 2020, 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 September 30, 2021 (dollars in thousands, except per share amounts): Shares Weighted- Weighted-Average Aggregate Outstanding at July 1, 2021 95,202 $ 24.35 5.21 $ 1,818 Granted — — Exercised (3,616) 17.55 Forfeited (250) 33.58 Expired — — Outstanding at September 30, 2021 91,336 24.59 5.02 1,858 Exercisable 72,843 22.28 4.12 1,650 Expected to vest, assuming a 0% forfeiture rate over the vesting term 91,336 $ 24.59 5.02 $ 1,858 The following is a summary of the Company’s stock option award activity during the nine months ended September 30, 2021 (dollars in thousands, except per share amounts): Shares Weighted- Weighted-Average Aggregate Outstanding at January 1, 2021 100,977 $ 22.00 4.71 $ 1,045 Granted 12,250 32.46 Exercised (20,651) 15.99 Forfeited (1,170) 34.93 Expired (70) 34.29 Outstanding at September 30, 2021 91,336 24.59 5.02 1,858 Exercisable 72,843 22.28 4.12 1,650 Expected to vest, assuming a 0% forfeiture rate over the vesting term 91,336 $ 24.59 5.02 $ 1,858 As of September 30, 2021, there was $91 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 2.6 years. 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 for the nine months ended September 30, 2021 and 2020 were determined using the following weighted-average assumptions as of the grant date. Nine Months Ended September 30, 2021 2020 Annual dividend yield 1.60 % 1.60 % Expected volatility 21.67 % 21.67 % Risk-free interest rate 0.60 % 1.38 % Expected term 6.50 years 6.50 years Weighted-average grant date fair value per option granted $ 5.64 $ 7.14 There were no options granted during the three months ended September 30, 2021 or 2020. 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 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 award activity during the three months ended September 30, 2021: Shares Weighted-Average Aggregate Intrinsic Value Per Share Non-Vested at July 1, 2021 18,050 $ 34.01 Granted — — Vested — — Forfeited (420) 33.45 Non-Vested at September 30, 2021 17,630 -0.0094814404432133 $ 34.02 $ 44.94 Expected to vest assuming a 0% forfeiture rate over the vesting term 17,630 $ 34.02 $ 44.94 The following is a summary of the Company’s non-vested restricted stock award activity during the nine months ended September 30, 2021: Shares Weighted-Average Aggregate Intrinsic Value Per Share Non-Vested at January 1, 2021 17,114 $ 35.03 Granted 10,168 32.46 Vested (7,762) 33.99 Forfeited (1,890) 34.93 Non-Vested at September 30, 2021 17,630 $ 34.02 $ 44.94 Expected to vest assuming a 0% forfeiture rate over the vesting term 17,630 $ 34.02 $ 44.94 As of September 30, 2021, there was $455 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 2.5 years. The total fair value of shares vested for the nine months ended September 30, 2021 and 2020 was $264 thousand and $236 thousand, respectively. Employee Stock Ownership Plan In January 2008, the ESOP borrowed $1.2 million from the Company to purchase common stock of the Company which was paid in full in 2017. In August 2012, in conjunction with the Company’s conversion to a full stock company from the mutual holding company structure, the ESOP borrowed an additional $1.1 million from the Company to purchase common stock of the Company. The loan is being repaid principally by the Bank through contributions to the ESOP over a period of ten years. The interest rate on the loan is fixed at 2.25% per annum. As of September 30, 2021, the remaining balance of the ESOP loan was $126 thousand. Neither the loan balance nor the related interest expense is reflected on the condensed consolidated financial statements. At September 30, 2021, the ESOP held and is committed to release 11,340 shares of the Company’s common stock to participants during 2021. The fair value of the 147,766 shares held by the ESOP trust was $6.8 million at September 30, 2021. ESOP compensation expense included in salaries and benefits was $180 thousand and $530 thousand for the three and nine months ended September 30, 2021, respectively, and $126 thousand and $474 thousand for the three and nine months ended September 30, 2020, respectively.

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, 2020, as filed with the SEC on March 30, 2021 (“2020 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.
Accounting Pronouncements Recently Issued or Adopted	Accounting Pronouncements Recently Issued or Adopted The Coronavirus Aid, Relief and Economic Security Act ("CARES Act"), signed into law on March 27, 2020, provides relief from certain accounting and financial reporting requirements under U.S. GAAP. Section 4013 of the CARES Act provides temporary relief from the accounting and reporting requirements for troubled debt restructurings (“TDRs”) under Accounting Standards Codification ("ASC") 310-40 for loan modifications related to the novel coronavirus disease 2019 ("COVID-19") pandemic. In addition, on April 7, 2020, a group of banking agencies issued an interagency statement (“Interagency Statement”) for evaluating whether loan modifications that occur in response to the COVID-19 pandemic are TDRs. The Interagency Statement was originally issued on March 22, 2020, but the banking agencies revised it to address the relationship between their TDR accounting and disclosure guidance and the TDR guidance in Section 4013 of the CARES Act. Section 4013 of the CARES Act permits the suspension of ASC 310-40 for loan modifications that are made by financial institutions in response to the COVID-19 pandemic if (1) the borrower was not more than 30 days past due as of December 31, 2019, and (2) the modifications are related to arrangements that defer or delay the payment of principal or interest, or change the interest rate on the loan. The Interagency Statement indicates that a lender can conclude that a borrower is not experiencing financial difficulty if either (1) short-term (e.g., six months) modifications are made in response to COVID-19, such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant related to loans in which the borrower is less than 30 days past due on its contractual payments at the time a modification program is implemented, or (2) the modification or deferral program is mandated by the federal government or a state government. Accordingly, any loan modification made in response to the COVID-19 pandemic that meets either of these practical expedients would not be considered a TDR. The Company adopted this guidance effective March 27, 2020. On December 27, 2020, the Consolidated Appropriations Act 2021 (“CAA 2021”) was signed into law. Among other purposes, CAA 2021 provides coronavirus emergency response and relief, including extending relief offered under the CARES Act related to restructured loans as a result of COVID-19 through January 1, 2022 or 60 days after the end of the national emergency declared by the President, whichever is earlier. In October 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-08, “ Receivables – Nonrefundable Fees and Other Costs ” (“ASU 2020-08”). ASU 2020-08 clarifies that the Company should reevaluate whether a callable debt security is within the scope of paragraph 310-20-35-33 for each reporting period. ASU 2020-08 is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The adoption of ASU 2018-13 did not have a material impact on the Company's consolidated financial statements. On March 2020, the 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 contract modifications 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 period 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 December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This ASU simplifies the accounting for income taxes by removing the exception to the incremental approach for intra-period tax allocation when there is a loss from continuing operations and income or a gain from other items, removing the requirement to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment, and removing the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The adoption of ASU 2019-12 did not have a material impact on the Company's consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans. This ASU modifies disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. Disclosure requirements removed from FASB Subtopic 715-20 include the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year, the amount and timing of plan assets expected to be returned to the employer, related party disclosures about the amount of future annual benefits covered by insurance and annuity contracts and significant transactions between the employer or related parties and the plan, and, for public entities, the effects of a one-percentage-point change in assumed health care cost trend rates on the aggregate of the service and interest cost components of net periodic benefit costs and benefit obligation for postretirement health care benefits. Disclosure requirements added to FASB Subtopic 715-20 include the weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates, and an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. This ASU is effective for fiscal years ending after December 15, 2020. The adoption of ASU No. 2018-14 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 . 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 change in allowance recognized as a result of adoption will occur through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the ASU is adopted. The new guidance may result in an increase in the allowance for loan losses; however, the Company is still in the process of determining the magnitude of the change and its impact on the Company's consolidated financial statements. The FASB issued ASU No. 2019-10, Financial Instruments - Credit Losses (Topic 326)
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 September 30, 2021 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 – Available-for-sale 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. 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 September 30, 2021 and December 31, 2020, 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 Debt - The fair value of subordinated debt 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: Impaired Loans - The fair value of collateral dependent loans 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 and nine months ended September 30, 2021 and 2020.
