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 (“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 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, 2019, as filed with the SEC on March 12, 2020 (“2019 Form 10-K”). The results for the interim periods are not necessarily indicative of results for a full year. 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, retained earnings, stockholders’ equity or earnings per share.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Accounting Pronouncements Recently Issued or Adopted	Accounting Pronouncements Recently Issued or Adopted On March 27, 2020, President Trump signed into law the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), which 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 ASC 310-40 for loan modifications related to the coronavirus disease (“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 the COVID-19 pandemic, 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. In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2020-04, Reference Rate Reform (Topic 848). This ASU provides optional guidance for a limited 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. The amendments in this update are effective for all entities as of 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 (ASU 2019-12). 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 Company does not expect the adoption of ASU 2019-12 to have a material impact on its 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 Company does not expect the adoption of ASU 2018-14 to have a material impact on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement: Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. This ASU modifies the disclosure requirements on fair value measurements by removing the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of transfers between levels, and the valuation processes for Level 3 fair value measurements. This ASU clarifies that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. The ASU adds disclosure requirements for Level 3 measurements, including changes in unrealized gains and losses for the period included in other comprehensive income for the recurring Level 3 fair value measurements held at the end of the reporting period, and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. Amendments in this ASU are effective for fiscal years beginning after December 15, 2019, 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. In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. This ASU amends the accounting for share-based payments awards to nonemployees to align with the accounting for employee awards. Under the new guidance, the existing employee guidance will apply to nonemployee share-based transactions (as long as the transaction is not effectively a form of financing), with the exception of specific guidance related to the attribution of compensation cost. The cost of nonemployee awards will continue to be recorded as if the grantor had paid cash for the goods or services. In addition, the contractual term will be able to be used in lieu of an expected term in the option-pricing model for nonemployee awards. Amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018 and early adoption is permitted. The adoption of ASU No. 2018-07 on January 1, 2019 did not have a material impact on the Company's consolidated financial statements. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This ASU amends the hedge accounting recognition and presentation requirements in ASC 815 to improve the transparency and understandability of information conveyed to financial statement users about an entity's risk management activities by better aligning the entity's financial reporting for hedging relationships with those risk management activities and reduce the complexity of and simplify the application of hedge accounting by preparers. The amendments in this ASU permit hedge accounting for hedging relationships involving nonfinancial risk and interest rate risk by removing certain limitations in cash flow and fair value hedging relationships. In addition, the ASU requires an entity to present the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedged item is reported. The amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018 and early adoption is permitted. The adoption of ASU No. 2017-12 on January 1, 2019, did not have a material impact on the Company's consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20) . ASU 2017-08 is intended to amend the amortization period for certain purchased callable debt securities held at a premium. Under ASU 2017-08, the FASB is shortening the amortization period for the premium to the earliest call date. Under current GAAP, entities generally amortize the premium as an adjustment of yield over the contractual life of the instrument. ASU 2017-08 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018. The adoption of ASU No. 2017-08 on January 1, 2019 did not have a material impact on the Company's consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment , or ASU 2017-04, which eliminates Step 2 from the goodwill impairment test. ASU 2017-04 also eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. Adoption of ASU 2017-04 is required for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019 with early adoption permitted for annual or interim goodwill impairment tests performed on testing dates after January 1, 2017. The Company’s adoption of ASU 2017-04 did not 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 . 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 FASB issued ASU 2019-10, Financial Instruments- Credit Losses (Topic 326) , delaying implementation of ASU 2016-13 for SEC smaller reporting company filers until fiscal year beginning after 2022. The Bank meets the requirements of a smaller reporting company and delayed implementation of ASU 2016-13. In February 2016, FASB issued ASU No. 2016-02, Leases (Topic 842) . ASU No. 2016-02 requires lessees to recognize, on the balance sheet, the assets and liabilities arising from operating leases. A lessee should recognize a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. A lessee should include payments to be made in an optional period only if the lessee is reasonably certain to exercise an option to extend the lease or not to exercise an option to terminate the lease. For a finance lease, interest payments should be recognized separately from amortization of the right-of-use asset in the statement of comprehensive income. For operating leases, the lease cost should be allocated over the lease term on a generally straight-line basis. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842), Targeted Improvements . This ASU amended the new leases standard to give entities another option for transition and to provide lessors with a practical expedient. The transition option allows entities to not apply the new leases standard in the comparative periods they present in their financial statements in the year of adoption. The practical expedient provides lessors with an option to not separate non-lease components from the associated lease components when certain criteria are met and requires them to account for the combined component in accordance with the new revenue standard if the associated non-lease components are the predominant components. The Company adopted these ASUs on January 1, 2019. In March 2019, FASB issued ASU 2019-01, Leases (Topic 842), Codification Improvements . The amendments in this ASU include determining the fair value of the underlying asset by lessors that are not manufacturers or dealers, requiring cash received from lessors from sales-type and direct financing leases to be presented in the cash flow statement within investing activities, and clarifying interim disclosure requirements. The effective date and transition requirements for the first and second items of this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2019 and early adoption is permitted. We have adopted the third item of this ASU and provided the required interim disclosures in this report. See Note 12- Leases for further information.

Investments [Abstract]
Investments	Investments The amortized cost and fair value of our available-for-sale (“AFS”) securities and the corresponding amounts of gross unrealized gains and losses at the dates indicated were as follows (in thousands): Amortized Gross Gross Estimated June 30, 2020 Municipal bonds $ 4,161 $ 202 $ — $ 4,363 Agency mortgage-backed securities 5,706 129 — 5,835 Total $ 9,867 $ 331 $ — $ 10,198 December 31, 2019 Municipal bonds $ 3,197 $ 173 $ — $ 3,370 Agency mortgage-backed securities 5,888 56 (8) 5,936 Total $ 9,085 $ 229 $ (8) $ 9,306 The amortized cost and fair value of AFS securities at June 30, 2020, by contractual maturity, are shown below (in thousands). 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. June 30, 2020 Amortized Fair Due within one year $ 1,043 $ 1,046 Due after one year through five years 490 508 Due after five years through ten years 1,433 1,485 Due after ten years 1,195 1,324 Mortgage-backed securities 5,706 5,835 Total $ 9,867 $ 10,198 There were no pledged securities at June 30, 2020 or December 31, 2019. There were no sales of AFS securities during the three and six months ended June 30, 2020 or 2019. There were no securities in gross unrealized position at June 30, 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 December 31, 2019 (in thousands): December 31, 2019 Less Than 12 Months 12 Months or Longer Total Fair Unrealized Fair Unrealized Fair Unrealized Municipal bonds $ 3,387 $ (8) $ — $ — $ 3,387 $ (8) Total $ 3,387 $ (8) $ — $ — $ 3,387 $ (8) There were no credit losses recognized in earnings during the three and six months ended June 30, 2020 or 2019 relating to the Company’s securities. At June 30, 2020, the securities portfolio consisted of 14 agency mortgage-backed securities and nine municipal securities with a total portfolio fair value of $10.2 million. At December 31, 2019, the securities portfolio consisted of 13 agency mortgage- backed securities and eight municipal securities with a fair value of $9.3 million. At June 30, 2020, there were no securities in an unrealized loss position for less than 12 months or more than 12 months. At December 31, 2019, there were five 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 June 30, 2020, 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 . Additional 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.

Federal regulations provide for the classification of lower quality loans as substandard, doubtful or loss. An asset is considered substandard if it is inadequately protected by the current net worth and payment capacity of the borrower or of any collateral pledged. Substandard assets include those characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected. Assets classified as doubtful have all the weaknesses inherent in assets classified substandard with the added characteristic that the weaknesses make collection or liquidation of the assets 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 establishment of a specific loss reserve is not warranted. When we classify problem loans as either substandard or doubtful, we may establish a specific allowance in an amount we deem prudent to address the risk specifically (if the loan is impaired) or we may allow the loss to be addressed in the general allowance (if the loan is not impaired). General allowances represent loss reserves 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 loans. When the Company classifies problem loans as a loss, we charge-off such assets in the period in which they are deemed uncollectible. Assets that do not currently expose us to sufficient risk to warrant classification as substandard, doubtful or loss, but possess identified weaknesses, are classified as either watch or special mention assets. 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, the Bank’s federal regulator, and the Washington Department of Financial Institutions, the Bank’s state banking regulator, both of whom can order the establishment of additional loss allowances. Pass rated loans are loans that are not otherwise classified or criticized.

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 are not placed on nonaccrual for short-term loan modifications made in response to the COVID-19 pandemic.

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 June 30, 2020 and December 31, 2019, by type of loan were as follows (in thousands): June 30, 2020 Recorded Investment Unpaid Principal Without With Total Related One-to-four family $ 6,114 $ 4,463 $ 1,531 $ 5,994 $ 199 Home equity 378 233 145 378 19 Commercial and multifamily 353 353 — 353 — Construction and land 38 — 38 38 6 Manufactured homes 371 103 262 365 214 Floating homes 282 282 — 282 — Other consumer 136 — 136 136 49 Commercial business 1,834 714 819 1,533 242 Total $ 9,506 $ 6,148 $ 2,931 $ 9,079 $ 729 December 31, 2019 Recorded Investment Unpaid Principal Without With Total Related One-to-four family $ 8,748 $ 7,236 $ 1,384 $ 8,620 $ 205 Home equity 335 256 79 335 25 Commercial and multifamily 353 353 — 353 — Construction and land 1,215 1,177 38 1,215 7 Manufactured homes 445 46 394 440 349 Floating homes 290 290 — 290 — Other consumer 143 — 143 143 54 Commercial business 997 714 283 997 84 Total $ 12,526 $ 10,072 $ 2,321 $ 12,393 $ 724 The following tables present the average recorded investment and interest income recognized on impaired loans for the three and six months ended June 30, 2020 and 2019, respectively, by loan types (in thousands): Three Months Ended June 30, 2020 Three Months Ended June 30, 2019 Average Interest Income Average Interest Income One-to-four family $ 5,961 $ 74 $ 2,536 $ 61 Home equity 368 4 549 9 Commercial and multifamily 353 5 585 8 Construction and land 255 (13) 124 2 Manufactured homes 396 6 475 18 Floating homes 403 — — — Other consumer 138 2 158 5 Commercial business 1,542 18 933 19 Total $ 9,416 $ 96 $ 5,360 $ 122 Six Months Ended June 30, 2020 Six Months Ended June 30, 2019 Average Interest Income Average Interest Income One-to-four family $ 6,847 $ 147 $ 3,590 $ 99 Home equity 357 9 682 15 Commercial and multifamily 353 10 1,607 15 Construction and land 575 1 424 4 Manufactured homes 411 15 431 28 Floating homes 366 8 — — Other consumer 139 4 163 8 Commercial business 1,360 41 1,274 37 Total $ 10,408 $ 235 $ 8,171 $ 206 Forgone interest on nonaccrual loans was $109,000 and $91,000 for the six months ended June 30, 2020 and 2019, respectively. There were no commitments to lend additional funds to borrowers whose loans were classified as nonaccrual or impaired at June 30, 2020 and December 31, 2019. Troubled debt restructurings. TDRs are accounted for under ASC 310-40, are loans 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 $5.7 million and $7.9 million at June 30, 2020 and December 31, 2019, 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 was one loan totaling $431,000 modified as a TDR during the three months ended June 30, 2020 and three loans totaling $649,000 modified as TDRs during the six months ended June 30, 2020. There was one TDR loan totaling $2.8 million paid-off during the six months ended June 30, 2020. There were no loans modified as TDRs during the three and six months ended June 30, 2019. Two TDR loans totaling $40,000 were paid off during the three months ended June 30, 2019, and three TDR loans totaling $145,000 were paid-off during the six months ended June 30, 2019. 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 six months ended June 30, 2020 and 2019. There was one loan totaling $161,000 modified as a TDR for which there was a payment default within the first 12 months of modification during the six months ended June 30, 2020. During the six months ended June 30, 2019, there were six loans totaling $297,000 modified as TDRs for which there was a payment default within the first 12 months of modification. 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 related bank regulatory guidance provides that a short-term modification made in response to COVID-19 and which meets certain criteria does not need to be accounted for as a TDR. As of June 30, 2020, the Company had approved 122 loan modifications related to the COVID-19 pandemic with an outstanding loan balance totaling $51.3 million in accordance with the CARES Act. Accordingly, the Company does not account for such loan modifications as TDRs. Loan modifications in accordance with the CARES Act and related regulatory guidance are still subject to an evaluation in regard to determining whether or not a loan is deemed to be impaired.

Fair Value Measurements

Fair Value Measurements	6 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 Accounting Standards Codification (“ASC”) 820, Fair Value Measurements , which provides a framework for measuring fair value in accordance with U.S. GAAP and requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 defines fair values for financial instruments as the exit price, the price that would be received for an asset or paid to transfer a liability, in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date under current market conditions. The Company’s fair values for financial instruments at June 30, 2020 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 - Residential mortgage loans held-for-sale are recorded at the lower of cost or fair value. The fair value of fixed-rate residential loans is based on whole loan forward prices obtained from government sponsored enterprises. At June 30, 2020 and December 31, 2019, 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. 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 are 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. 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 June 30, 2020 and December 31, 2019 (in thousands): June 30, 2020 Fair Value Measurements Using: Carrying Estimated Level 1 Level 2 Level 3 FINANCIAL ASSETS: Cash and cash equivalents $ 130,537 $ 130,537 $ 130,537 $ — $ — Available-for-sale securities 10,198 10,198 — 10,198 — Loans held-for-sale 7,364 7,364 — 7,364 — Loans held-for-portfolio, net 684,672 696,385 — — 696,385 Mortgage servicing rights 3,113 3,113 — — 3,113 FHLB stock 1,164 1,164 — 1,164 — FINANCIAL LIABILITIES: Non-maturity deposits 455,480 455,480 — 455,480 — Time deposits 238,842 243,721 — 243,721 — FHLB and other Borrowings 79,841 79,841 — 79,841 — December 31, 2019 Fair Value Measurements Using: Carrying Estimated Level 1 Level 2 Level 3 FINANCIAL ASSETS: Cash and cash equivalents $ 55,770 $ 55,770 $ 55,770 $ — $ — Available-for-sale securities 9,306 9,306 — 9,306 — Loans held-for-sale 1,063 1,063 — 1,063 — Loans held-for-portfolio, net 614,247 622,147 — — 622,147 Mortgage servicing rights 3,239 3,239 — — 3,239 FHLB stock 1,160 1,160 — 1,160 — FINANCIAL LIABILITIES: Non-maturity deposits 365,331 365,331 — 365,331 — Time deposits 251,387 255,261 — 255,261 — FHLB Borrowings 7,500 7,500 — 7,500 — The following tables present the balance of assets measured at fair value on a recurring basis as of June 30, 2020 and December 31, 2019 (in thousands): Fair Value at June 30, 2020 Description Total Level 1 Level 2 Level 3 Municipal bonds $ 4,363 $ — $ 4,363 $ — Agency mortgage-backed securities 5,835 — 5,835 — Mortgage servicing rights 3,113 — — 3,113 Fair Value at December 31, 2019 Description Total Level 1 Level 2 Level 3 Municipal bonds $ 3,370 $ — $ 3,370 $ — Agency mortgage-backed securities 5,936 — 5,936 — Mortgage servicing rights 3,239 — — 3,239 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 at June 30, 2020 and December 31, 2019: June 30, 2020 Financial Instrument Valuation Technique Unobservable Input(s) Range Mortgage Servicing Rights Discounted cash flow Prepayment speed assumption 152%-238% (216%) Discount rate 10%-12% (10.1%) December 31, 2019 Financial Instrument Valuation Technique Unobservable Input(s) Range Mortgage Servicing Rights Discounted cash flow Prepayment speed assumption 132%-485% (187%) Discount rate 12.5%-13.5% (12.5%) 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 six months ended June 30, 2020 and June 30, 2019.

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 pursuant to the two-class method. 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. The following table summarizes the calculation of earnings per share for the periods indicated (in thousands, except per share data): Three Months Ended June 30, Six Months Ended June 30, 2020 2019 2020 2019 Net income available to common shareholders $ 2,113 $ 1,817 $ 3,094 $ 3,261 Weighted-average number of shares outstanding, basic 2,560 2,522 2,553 2,516 Effect of potentially dilutive common shares 20 50 32 57 Weighted-average number of shares outstanding, diluted 2,580 2,572 2,585 2,573 Earnings per share, basic $ 0.83 $ 0.72 $ 1.21 $ 1.29 Earnings per share, diluted $ 0.82 $ 0.71 $ 1.20 $ 1.27 There were 6,809 anti-dilutive securities at June 30, 2020 and no anti-dilutive securities at June 30, 2019.

Share-based Payment Arrangement [Abstract]
Stock-based Compensation	Stock-based CompensationStock Options and Restricted Stock The Company currently has one active shareholder approved Equity Incentive Plan, the Amended and Restated 2013 Equity Incentive Plan (the "2013 Plan"). The 2013 Plan permits the grant of restricted stock, restricted stock units, stock options, and stock appreciation rights. The equity incentive plan approved by stockholders in 2008 (the"2008 Plan") expired in November 2018 and no further awards may be made under the 2008 Plan; provided, however, all awards outstanding under the 2008 Plan remain outstanding in accordance with their terms. Under the 2013 Plan, 181,750 shares of common stock were approved for awards for stock options and stock appreciation rights and 116,700 shares of common stock were approved for awards for restricted stock and restricted stock units. As of June 30, 2020, on an adjusted basis, awards for stock options totaling 267,752 shares and awards for restricted stock totaling 134,148 shares of Company common stock have been granted, net of any forfeitures, to participants in the Plans. Share-based compensation expense was $46,000 and $231,000 for the three and six months ended June 30, 2020, respectively, and was $48,000 and $87,000 or the three and six months ended June 30, 2019, respectively. Stock Option Awards All stock option awards granted under the 2008 Plan vest in 20 percent annual increments commencing one year from the grant date in accordance with the requirements of the 2008 Plan. 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 Company. All of the options granted under the 2008 Plan and the 2013 Plan are exercisable for a period of 10 years from the date of grant, subject to vesting.

The cost is expected to be recognized over the remaining weighted-average vesting period of approximately 2.89 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 six months ended June 30, 2020 and 2019 were determined using the following weighted-average assumptions as of the grant date. June 30, 2020 June 30, 2019 Annual dividend yield 1.60 % 1.72 % Expected volatility 21.67 % 21.68 % Risk-free interest rate 1.38 % 2.64 % Expected term 6.50 years 6.50 years Weighted-average grant date fair value per option granted $ 7.14 $ 7.24 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 six months ended June 30, 2020: Shares Weighted-Average Aggregate Intrinsic Value Per Share Non-vested at January 1, 2020 12,290 $ 33.32 Granted 13,600 36.26 Vested (6,816) 34.60 Forfeited (1,690) 34.15 Non-Vested at June 30, 2020 17,384 $ 35.03 $ 24.15 Expected to vest assuming a 0% forfeiture rate over the vesting term 17,384 $ 35.03 $ 24.15 As of June 30, 2020, there was $535,000 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 3.12 years. The total fair value of shares vested for the six months ended June 30, 2020 and 2019 was $236,000 and $95,000, 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 June 30, 2020, the remaining balance of the ESOP loan was $126,000. Neither the loan balance nor the related interest expense is reflected on the condensed consolidated financial statements. For the calendar year 2020, the ESOP was committed to release 11,340 shares of the Company’s common stock to participants and held 11,340 unallocated shares remaining to be released in 2021. The fair value of the 142,463 shares held by the ESOP trust was $3.4 million at June 30, 2020. ESOP compensation expense included in salaries and benefits was $174,000 and $348,000 for the three and six months ended June 30, 2020, respectively, and was $168,000 and $336,000 for the three and six months ended June 30, 2019, respectively.

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Revenue from Contracts with Customers All of the Company's revenue from contracts with customers in the scope of ASC 606 - Revenue from Contracts with Customers ("ASC 606") is recognized in Noninterest Income with the exception of the net loss on OREO and repossessed assets, which is included in Noninterest Expense. The following table presents the Company's sources of Noninterest Income for the three and six months ended June 30, 2020 and 2019 (in thousands). Items outside of the scope of ASC 606 are noted as such. Three Months Ended June 30, Six Months Ended June 30, 2020 2019 2020 2019 Noninterest income: Service charges and fee income Account maintenance fees $ 45 $ 45 $ 139 $ 96 Transaction-based and overdraft service charges 58 115 158 219 Debit/ATM interchange fees 242 250 472 463 Credit card interchange fees 5 7 12 13 Loan fees (a) 63 45 112 105 Other fees (a) 16 17 30 29 Total service charges and fee income 429 479 923 925 Earnings on cash surrender value of bank-owned life insurance (a) 90 78 105 186 Mortgage servicing income (a) 235 256 479 498 Fair value adjustment on mortgage servicing rights (a) (437) (162) (800) (486) Net gain on sale of loans (a) 1,262 204 1,581 695 Total noninterest income $ 1,579 $ 855 $ 2,288 $ 1,818 (a) Not within scope of Topic 606 Account maintenance fees and transaction-based and overdraft service charges The Company earns fees from its customers for account maintenance, transaction-based and overdraft services. Account maintenance fees consist primarily of account fees and analyzed account fees charged on deposit accounts on a monthly basis. The performance obligation is satisfied and fees are recognized on a monthly basis as the service period is completed. Transaction-based fees and overdraft service fees on deposit accounts are charged to deposit customers for specific services provided to the customer, such as non-sufficient funds, overdraft, and wire services. The performance obligation is completed as the transaction occurs and the fees are recognized at the time each specific service is provided to the customer. Debit/ATM and credit card interchange income Debit/ATM interchange income represent fees earned when a debit card issued by the Bank is used for a transaction. The Bank earns interchange fees from debit cardholder transactions through the MasterCard payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the cardholders' account. Certain expenses directly associated with the debit card are recorded on a net basis with the interchange income. The Company utilizes a third-party agency relationship to brand credit cards with fees for originating new accounts paid by the issuing bank. Credit card interchange income represents fees earned when a credit card is issued by the third-party agent. Similar to debit card interchange fees, the Bank earns an interchange fee for each transaction made with Sound Community Bank's branded credit cards. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the cardholders' credit card. Certain expenses and rebates directly related to the credit card interchange contract are recorded net of the interchange income. Net loss on OREO and repossessed assets We record a gain or loss from the sale of other real estate owned when control of the property transfers to the buyer, which generally occurs at the time of an executed deed of trust. When the Bank finances the sale of other real estate owned to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the other real estate owned asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on sale, we adjust the transaction price and related gain or loss on sale if a significant financing component is present. The

Organization, Consolidation and Presentation of Financial Statements [Abstract]
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 (“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 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, 2019, as filed with the SEC on March 12, 2020 (“2019 Form 10-K”). The results for the interim periods are not necessarily indicative of results for a full year. 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, retained earnings, stockholders’ equity or earnings per share.
Accounting Pronouncements Recently Issued or Adopted	Accounting Pronouncements Recently Issued or Adopted On March 27, 2020, President Trump signed into law the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), which 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 ASC 310-40 for loan modifications related to the coronavirus disease (“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 the COVID-19 pandemic, 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. In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2020-04, Reference Rate Reform (Topic 848). This ASU provides optional guidance for a limited 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. The amendments in this update are effective for all entities as of 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 (ASU 2019-12). 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 Company does not expect the adoption of ASU 2019-12 to have a material impact on its 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 Company does not expect the adoption of ASU 2018-14 to have a material impact on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement: Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. This ASU modifies the disclosure requirements on fair value measurements by removing the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of transfers between levels, and the valuation processes for Level 3 fair value measurements. This ASU clarifies that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. The ASU adds disclosure requirements for Level 3 measurements, including changes in unrealized gains and losses for the period included in other comprehensive income for the recurring Level 3 fair value measurements held at the end of the reporting period, and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. Amendments in this ASU are effective for fiscal years beginning after December 15, 2019, 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. In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. This ASU amends the accounting for share-based payments awards to nonemployees to align with the accounting for employee awards. Under the new guidance, the existing employee guidance will apply to nonemployee share-based transactions (as long as the transaction is not effectively a form of financing), with the exception of specific guidance related to the attribution of compensation cost. The cost of nonemployee awards will continue to be recorded as if the grantor had paid cash for the goods or services. In addition, the contractual term will be able to be used in lieu of an expected term in the option-pricing model for nonemployee awards. Amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018 and early adoption is permitted. The adoption of ASU No. 2018-07 on January 1, 2019 did not have a material impact on the Company's consolidated financial statements. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This ASU amends the hedge accounting recognition and presentation requirements in ASC 815 to improve the transparency and understandability of information conveyed to financial statement users about an entity's risk management activities by better aligning the entity's financial reporting for hedging relationships with those risk management activities and reduce the complexity of and simplify the application of hedge accounting by preparers. The amendments in this ASU permit hedge accounting for hedging relationships involving nonfinancial risk and interest rate risk by removing certain limitations in cash flow and fair value hedging relationships. In addition, the ASU requires an entity to present the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedged item is reported. The amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018 and early adoption is permitted. The adoption of ASU No. 2017-12 on January 1, 2019, did not have a material impact on the Company's consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20) . ASU 2017-08 is intended to amend the amortization period for certain purchased callable debt securities held at a premium. Under ASU 2017-08, the FASB is shortening the amortization period for the premium to the earliest call date. Under current GAAP, entities generally amortize the premium as an adjustment of yield over the contractual life of the instrument. ASU 2017-08 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018. The adoption of ASU No. 2017-08 on January 1, 2019 did not have a material impact on the Company's consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment , or ASU 2017-04, which eliminates Step 2 from the goodwill impairment test. ASU 2017-04 also eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. Adoption of ASU 2017-04 is required for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019 with early adoption permitted for annual or interim goodwill impairment tests performed on testing dates after January 1, 2017. The Company’s adoption of ASU 2017-04 did not 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 . 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 FASB issued ASU 2019-10, Financial Instruments- Credit Losses (Topic 326) , delaying implementation of ASU 2016-13 for SEC smaller reporting company filers until fiscal year beginning after 2022. The Bank meets the requirements of a smaller reporting company and delayed implementation of ASU 2016-13. In February 2016, FASB issued ASU No. 2016-02, Leases (Topic 842) . ASU No. 2016-02 requires lessees to recognize, on the balance sheet, the assets and liabilities arising from operating leases. A lessee should recognize a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. A lessee should include payments to be made in an optional period only if the lessee is reasonably certain to exercise an option to extend the lease or not to exercise an option to terminate the lease. For a finance lease, interest payments should be recognized separately from amortization of the right-of-use asset in the statement of comprehensive income. For operating leases, the lease cost should be allocated over the lease term on a generally straight-line basis. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842), Targeted Improvements . This ASU amended the new leases standard to give entities another option for transition and to provide lessors with a practical expedient. The transition option allows entities to not apply the new leases standard in the comparative periods they present in their financial statements in the year of adoption. The practical expedient provides lessors with an option to not separate non-lease components from the associated lease components when certain criteria are met and requires them to account for the combined component in accordance with the new revenue standard if the associated non-lease components are the predominant components. The Company adopted these ASUs on January 1, 2019. In March 2019, FASB issued ASU 2019-01, Leases (Topic 842), Codification Improvements
Fair Value Measurements	The Company determines the fair values of its financial instruments based on the requirements established in Accounting Standards Codification (“ASC”) 820, Fair Value Measurements , which provides a framework for measuring fair value in accordance with U.S. GAAP and requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 defines fair values for financial instruments as the exit price, the price that would be received for an asset or paid to transfer a liability, in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date under current market conditions. The Company’s fair values for financial instruments at June 30, 2020 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 - Residential mortgage loans held-for-sale are recorded at the lower of cost or fair value. The fair value of fixed-rate residential loans is based on whole loan forward prices obtained from government sponsored enterprises. At June 30, 2020 and December 31, 2019, 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. 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 are 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.
