Accounting Standards Update and Change in Accounting Principle [Abstract]
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Recent Accounting Pronouncements Adopted in 2021 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 (i) 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; (ii) the requirement to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment, and (iii) the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The Company adopted this ASU in January 2021 with no material impact on its consolidated financial statements. In October 2020, the FASB issued 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. The Company adopted this ASU in January 2021 with no material impact on its consolidated financial statements. Recent Accounting Pronouncements ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) as amended by ASU 2018-19, ASU 2019-04 and ASU 2019-05, was originally issued in June 2016 .

The Bank is a portfolio lender, originating and purchasing one-to-four family residential, multifamily, commercial real estate, construction/land development, business, and consumer loans.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and footnotes required by U.S. Generally Accepted Accounting Principles (“GAAP”) for complete financial statements. These unaudited interim consolidated 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 (“2020 Form 10-K”). In our opinion, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation of the unaudited interim consolidated financial statements in accordance with GAAP have been included. All significant intercompany balances and transactions between the Company and its subsidiaries have been eliminated in consolidation. Operating results for the three months ended March 31, 2021, are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. In preparing the unaudited consolidated financial statements, we are required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the allowance for loan and lease losses (“ALLL”), the valuation of other real estate owned (“OREO”) and the underlying collateral of impaired loans, deferred tax assets, the right-of-use asset and lease liability on our operating leases, and the fair value of financial instruments. The Company’s activities are considered to be a single industry segment for financial reporting purposes. The Company is engaged in the business of attracting deposits from the general public and originating and purchasing loans for its portfolio. Substantially all income is derived from a diverse base of commercial, multifamily, and residential real estate loans, consumer lending activities, and investments. Certain amounts in the unaudited interim consolidated financial statements for prior periods have been reclassified to conform to the current unaudited financial statement presentation with no effect on consolidated net income or stockholders’ equity.

The Company considers many factors including the severity and duration of the impairment, recent events specific to the issuer or industry, and for debt securities, external credit ratings and recent downgrades. Securities on which there is an unrealized loss that is deemed to be an other-than-temporary impairment (“OTTI”) are written down to fair value. If the Company intends to sell a debt security, or it is likely that the Company will be required to sell the debt security before recovering its cost basis, the entire impairment loss would be recognized in earnings as an OTTI. If the Company does not intend to sell the debt security and it is not likely that it will be required to sell the debt security but does not expect to recover the entire amortized cost basis of the debt security, only the portion of the impairment loss representing credit losses would be recognized in earnings. The credit loss on a debt security is measured as the difference between the amortized cost basis and the present value of the cash flows expected to be collected. Projected cash flows are discounted by the original or current effective interest rate depending on the nature of the debt security being measured for potential OTTI. The remaining impairment related to all other factors, the difference between the present value of the cash flows expected to be collected and fair value, is recognized as a charge to other comprehensive income (“OCI”). Impairment losses related to all other factors are presented as separate categories within OCI. The Company had 44 securities and 20 securities in an unrealized loss position, respectively, with 15 and 18 of these securities in an unrealized loss position for 12 months or more, at both March 31, 2021, and December 31, 2020, respectively. Management does not believe that any individual unrealized loss as of March 31, 2021, or December 31, 2020, represented OTTI. The decline in fair market value of these securities was generally due to changes in interest rates and changes in market-desired spreads subsequent to their purchase. Management also reviewed the financial condition of the entities issuing municipal or corporate bonds at March 31, 2021, and December 31, 2020, and determined that an OTTI charge was not warranted. The amortized cost and estimated fair value of investments available-for-sale at March 31, 2021, by contractual maturity, are shown below. Expected maturities will 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. March 31, 2021 Amortized Cost Fair Value (In thousands) Due after one year through five years $ 8,908 $ 8,946 Due after five years through ten years 16,134 16,232 Due after ten years 79,074 78,671 104,116 103,849 Mortgage-backed investments 64,013 64,193 Total $ 168,129 $ 168,042 Under Washington state law, in order to participate in the public funds program the Company is required to pledge eligible securities as collateral in an amount equal to 50% of the public deposits held less the FDIC insured amount. Investment securities with market values of $24.2 million and $23.4 million were pledged as collateral for public deposits at March 31, 2021, and December 31, 2020, respectively, both of which exceeded the collateral requirements established by the Washington Public Deposit Protection Commission. For the three months ended March 31, 2021, there was a $2.0 million call on one investment security that did not generate a gain or loss. For the three months ended March 31, 2020, there were no calls, sales, or maturities on investment securities. In January 2020, the Bank purchased three annuity contracts, totaling $2.4 million, to be held long-term to satisfy the benefit obligation associated with certain supplemental executive retirement plan agreements. At March 31, 2021, the annuities were reported as investments held-to-maturity at an amortized cost of $2.4 million on the Company’s Consolidated Balance Sheet. The amortized cost is considered the fair value of the investment.

In addition, loans totaling $127.4 million and $127.1 million were pledged to the Federal Reserve Bank of San Francisco to secure a line of credit at March 31, 2021 and December 31, 2020, respectively. Credit Quality Indicators . The Company assigns a risk rating to all credit exposures based on a risk rating system designed to define the basic characteristics and identified risk elements of each credit extension. The Company utilizes a nine point risk rating system. A description of the general characteristics of the risk grades is as follows: • Grades 1 through 5: These grades are considered to be “pass” credits. These include assets where there is virtually no credit risk, such as cash secured loans with funds on deposit with the Bank. Pass credits also include credits that are on the Company’s watch list (grade 5), where the borrower exhibits potential weaknesses, which may, if not checked or corrected, negatively affect the borrower’s financial capacity and threaten their ability to fulfill debt obligations in the future. • Grade 6: These credits, classified as “special mention”, possess weaknesses that deserve management’s close attention. Special mention assets do not expose the Company to sufficient risk to warrant adverse classification in the substandard, doubtful or loss categories. If left uncorrected, these potential weaknesses may result in deterioration in the Company’s credit position at a future date. • Grade 7: These credits, classified as “substandard”, present a distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. These credits have well defined weaknesses which jeopardize the orderly liquidation of the debt and are inadequately protected by the current net worth and payment capacity of the borrower or of any collateral pledged. • Grade 8: These credits are classified as “doubtful” and possess well defined weaknesses which make the full collection or liquidation of the loan highly questionable and improbable. This classification is used where significant risk exposures are perceived but the exact amount of the loss cannot yet be determined due to pending events. • Grade 9: Assets classified as “loss” are considered uncollectible and cannot be justified as a viable asset for the Company. There is little or no prospect of near term recovery and no realistic strengthening action of significance is pending. Loan grades are used by the Company to identify and track potential problem loans which do not rise to the levels described for substandard, doubtful, or loss. The grades for watch and special mention are assigned to loans which have been criticized based upon known characteristics such as periodic payment delinquency, failure to comply with contractual terms of the loan or stale financial information from the borrower and/or guarantors. Loans identified as criticized (watch and special mention) or classified (substandard, doubtful or loss) are subject to problem loan reporting every three months. As of March 31, 2021, and December 31, 2020, the Company had no loans rated as doubtful or loss. The following tables represent a summary of loans at March 31, 2021, and December 31, 2020 by type and risk category: March 31, 2021 One-to-Four Multifamily Commercial Construction/ Business Consumer Total (In thousands) Risk Rating: Pass, grade 1-4 $ 374,330 $ 135,685 $ 317,968 $ 92,294 $ 77,851 $ 38,731 $ 1,036,859 Pass, grade 5 (watch) 3,969 2,347 41,193 2,251 443 37 50,240 Special mention 422 — 26,309 — — — 26,731 Substandard 525 2,036 — — — — 2,561 Total loans $ 379,246 $ 140,068 $ 385,470 $ 94,545 $ 78,294 $ 38,768 $ 1,116,391 December 31, 2020 One-to-Four Multifamily Commercial Construction/ Business Consumer Total (In thousands) Risk Rating: Pass, grade 1-4 $ 376,918 $ 132,243 $ 316,955 $ 89,957 $ 80,208 $ 40,477 $ 1,036,758 Pass, grade 5 (watch) 3,914 2,347 52,375 2,250 455 144 61,485 Special mention 601 — 15,935 — — — 16,536 Substandard 527 2,104 — — — — 2,631 Total loans $ 381,960 $ 136,694 $ 385,265 $ 92,207 $ 80,663 $ 40,621 $ 1,117,410 ALLL . When the Company classifies problem assets as either substandard or doubtful, pursuant to Federal regulations, or identifies a loan where it is uncertain if the Bank will be able to collect all amounts due according to the contractual terms of the loan, it may establish a specific reserve in an amount deemed prudent to address the risk specifically. 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 the particular problem assets. When an insured institution classifies problem assets as a loss, pursuant to Federal regulations, it is required to charge-off such assets in the period in which they are deemed uncollectible. The determination as to the classification of the Company’s assets and the amount of valuation allowances is subject to review by bank regulators, who can require the establishment of additional allowances for loan losses. In February 2021, the Company received notification that $5.4 million in commercial real estate participation loans had been downgraded by the lead bank to special mention. To date, the Company has not received sufficient information to make a final determination, and accordingly, the risk rating on these loans have not been further downgraded. At March 31, 2021, these loans that are secured by nursing home/rehabilitation facilities were current on their payments. At March 31, 2021, total loans receivable included $45.2 million of loans originated under the Small Business Administration (“SBA”) Paycheck Protection Program (“PPP”). PPP loans are 100% guaranteed by the SBA. Although these loans were included in the population of loans collectively evaluated for impairment, no general reserve was allocated to them as these loans are 100% guaranteed by the SBA.

Certain loan modifications are accounted for as troubled debt restructured loans (“TDRs”). At March 31, 2021, the TDR portfolio totaled $3.8 million. At December 31, 2020, the TDR portfolio totaled $3.9 million. At both dates, all TDRs were performing according to their modified repayment terms. At March 31, 2021, the Company had no commitments to extend additional credit to borrowers whose loan terms have been modified in TDRs. All TDRs are also classified as impaired loans and are included in the loans individually evaluated for impairment as part of the calculation of the ALLL. No loans accounted for as TDRs were charged-off to the ALLL for the three months ended March 31, 2021 and 2020. The Coronavirus Aid, Relief, and Economic Security Act of 2020 ("CARES Act"), signed into law on March 27, 2020, provided guidance around the modification of loans as a result of the COVID-19 pandemic, which outlined, among other criteria, that short-term modifications made on a good faith basis to borrowers who were current as defined under the CARES Act prior to any relief, are not TDRs. This includes short-term (e.g. generally up to six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant. To qualify as an eligible loan under the CARES Act, a loan modification must be (1) related to the COVID-19 pandemic; (2) executed on a loan that was not more than 30 days past due as of December 31, 2019; and (3) executed between March 1, 2020, and the earlier of (A) 60 days after the date of termination of the National Emergency by the President or (B) January 1, 2022. At March 31, 2021, total loans receivable included $56.7 million of loans that were on active short-term deferrals under the CARES Act and related regulatory guidance. Loan modifications in accordance with the CARES Act are still subject to an impairment evaluation. The following table presents TDR modifications during the three months ended March 31, 2021, and the recorded investment prior to and after the modification. There were no TDR modifications for the three months ended March 31, 2020.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value The Company measures the fair value of financial instruments for reporting in accordance with Accounting Standards Codification (“ASC”) Topic 820, Fair Value Measurements. Fair values of assets or liabilities are based on estimates of the exit price, which is the price that would be received to sell an asset or paid to transfer a liability. When available, observable market transactions or market information is used. The fair value estimate of loans receivable was based on similar techniques, with the addition of current origination spreads, liquidity premiums, or credit adjustments. The fair value of nonperforming loans is based on the underlying value of the collateral. The Company determines the fair values of its financial instruments based on the fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair values. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect its estimate for market assumptions. Valuation inputs refer to the assumptions market participants would use in pricing a given asset or liability using one of the three valuation techniques. Inputs can be observable or unobservable. Observable inputs are those assumptions that market participants would use in pricing the particular asset or liability. These inputs are based on market data and are obtained from an independent source. Unobservable inputs are assumptions based on the Company’s own information or estimate of assumptions used by market participants in pricing the asset or liability. Unobservable inputs are based on the best and most current information available on the measurement date. All inputs, whether observable or unobservable, are ranked in accordance with a prescribed fair value hierarchy: • Level 1 - Quoted prices for identical instruments in active markets. • Level 2 - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable. • Level 3 - Instruments whose significant value drivers are unobservable. The Company used the following methods to measure fair value on a recurring or nonrecurring basis: • Investments available-for-sale: The fair value of all investments, excluding FHLB stock, was based upon quoted market prices for similar investments in active markets, identical or similar investments in markets that are not active, and model-derived valuations whose inputs are observable. • Impaired loans: The fair value of impaired loans is measured using the present value of expected future cash flows discounted at the loan’s effective interest rate. When the sole source of repayment of the loan is the operation or liquidation of the collateral, the fair value is determined using the observable market price less certain completion costs and completion costs. • OREO: The fair value of OREO properties is measured at the lower of the carrying amount or fair value, less costs to sell. Fair values are generally based on third party appraisals of the property, resulting in a Level 3 classification. in cases where the carrying amount exceeds the fair value, less costs to sell, an impairment loss is recognized. • Derivatives: The fair value of derivatives is based on pricing models utilizing observable market data and discounted cash flow methodologies for which the determination of fair value may require significant management judgment or estimation. The tables below present the balances of assets and liabilities measured at fair value on a recurring basis (there were no transfers between Level 1, Level 2 and Level 3 recurring measurements) at March 31, 2021 and December 31, 2020: Fair Value Measurements at March 31, 2021 Fair Value Measurements Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (In thousands) Investments available-for-sale: Mortgage-backed investments: Fannie Mae $ 15,748 $ — $ 15,748 $ — Freddie Mac 12,851 — 12,851 — Ginnie Mae 25,090 — 25,090 — Other 10,504 — 10,504 — Municipal bonds 31,438 — 31,438 — U.S. Government agencies 50,356 — 50,356 — Corporate bonds 22,055 — 22,055 — Total available-for-sale investments 168,042 — 168,042 — Derivative fair value asset 903 — 903 — $ 168,945 $ — $ 168,945 $ — Fair Value Measurements at December 31, 2020 Fair Value Measurements Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (In thousands) Assets: Investments available-for-sale: Mortgage-backed investments: Fannie Mae $ 13,288 $ — $ 13,288 $ — Freddie Mac 4,316 — 4,316 — Ginnie Mae 17,127 — 17,127 — Other 10,729 — 10,729 — Municipal bonds 17,446 — 17,446 — U.S. Government agencies 40,635 — 40,635 — Corporate bonds 24,010 — 24,010 — Total available-for-sale investments 127,551 — 127,551 — Liabilities: Derivative fair value liability $ 2,825 $ — $ 2,825 $ — The estimated fair value of Level 2 investments is based on quoted prices for similar investments in active markets, identical or similar investments in markets that are not active and model-derived valuations whose inputs are observable.

The fair value of impaired loans reflects the exit price and is calculated using the collateral value method or on a discounted cash flow basis.

Leases

Leases [Abstract]
Leases	Leases The Company follows ASC Topic 842, Leases, recognizing a ROU and related lease liabilities on the Company’s consolidated balance sheets. At March 31, 2021, the Company had 13 operating leases for retail branch locations. The remaining lease terms range from three months to 9.8 years, with most leases carrying optional extensions of 3-5 years. The Company will include optional lease term extensions in the ROU and lease liabilities when management believes it is reasonably certain that the term extension will be exercised, and will be determined based on indicators that the Company would have an economic incentive to extend the lease. The Company has elected to not apply ASU 2016-02 to short term leases, which are those that have a term of one year or less. To calculate the present value of lease payments not yet paid, the Company uses the incremental borrowing rate, which is equal to the FHLB advance rate for the remaining term of the lease at the time of the lease inception, or at January 1, 2019, for leases in place at that date. The minimum monthly lease payments are generally based on square footage of the leased premises, with escalating minimum rent over the lease term. At March 31, 2021, the Company was committed to paying $68,000 per month in minimum monthly lease payments. The minimum monthly lease payment over the initial lease term, including any free rent period, was used to calculate the ROU and lease liability. The Company’s current leases do not include any non-lease components. Total lease expense included in the Company’s Consolidated Income Statements includes the amortized lease expense under ASC Topic 842, Leases, combined with variable lease expenses for maintenance or other expenses as defined in the individual lease agreements. The following table includes details on these items at and for the three months ended March 31, 2021, and 2020.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives The Company uses derivative financial instruments, in particular, interest rate swaps, which qualify as cash flow hedges, to manage the risk of changes in future cash flows due to interest rate fluctuations. At March 31, 2021, the Company held six interest rate swap agreements with initial terms of four seven Quarterly, the effectiveness evaluation is based upon the fluctuation of the interest the Company pays to the FHLB for the debt utilized to fund the interest rate swap as compared to the one-month or three-month LIBOR interest received from the counterparty. At March 31, 2021, a $903,000 net fair value asset of the cash flow hedges was reported with other assets. The tax effected amount of $713,000 was included in accumulated other comprehensive income. There were no amounts recorded in the Consolidated Income Statements for the quarters ended March 31, 2021 or 2020, related to ineffectiveness. Fair value for these derivative instruments, which generally changes as a result of changes in the level of market interest rates, is estimated based on dealer quotes and secondary market sources. The following table presents the fair value of these derivative instruments as of March 31, 2021 and December 31, 2020: Balance Sheet Location Fair Value at Fair Value at (In thousands) Interest rate swaps on FHLB debt Other Assets $ 903 $ (2,825) The following table presents the net unrealized gains and losses, net of tax, from these derivative instruments included on the Consolidated Statements of Comprehensive Income at the dates indicated: Amount Recognized in OCI for the Amount Recognized in OCI for the (In thousands) Interest rate swaps on FHLB debt designated as a cash flow hedge $ 2,945 $ (2,933)

Stock-Based Compensation

Share-based Payment Arrangement, Noncash Expense [Abstract]
Stock-Based Compensation	Stock-Based Compensation In June 2016, First Financial Northwest’s shareholders approved the First Financial Northwest, Inc. 2016 Equity Incentive Plan (“2016 Plan”). This plan provides for the granting of incentive stock options (“ISO”), non-qualified stock options (“NQSO”), restricted stock and restricted stock units until June 2026. The 2016 Plan established 1,400,000 shares available to grant with a maximum of 400,000 of these shares available to grant as restricted stock awards. Each share issued as a restricted stock award counts as two shares towards the total shares available to award. Under the 2016 Plan, the vesting date for each option award or restricted stock award is determined by an award committee and specified in the award agreement. In the case of restricted stock awards granted in lieu of cash payments of directors’ fees, the grant date is used as the vesting date unless the award agreement provides otherwise. As a result of the approval of the 2016 Plan, the First Financial Northwest, Inc. 2008 Equity Incentive Plan (“2008 Plan”) was frozen and no additional awards will be made. At March 31, 2021, there were 311,000 stock options from the 2008 Plan vested and available for exercise at March 31, 2021, subject to the 2008 Plan provisions. At March 31, 2021, there were 1,081,082 total shares available for grant under the 2016 Plan, including 240,541 shares available to be granted as restricted stock. For the three months ended March 31, 2021 and 2020, total compensation expense for both the 2008 Plan and 2016 Plan was $96,000 and $80,000, respectively, and the related income tax benefit was $20,000 and $17,000, respectively. Stock Options Under the 2008 Plan, stock option awards were granted with an exercise price equal to the market price of First Financial Northwest’s common stock at the grant date. These option awards have a vesting period of five years, with 20% vesting on the anniversary date of each grant date, and a contractual life of ten years. Any unexercised stock options expire ten years after the grant date, or sooner in the event of the award recipient’s death, disability or termination of service with the Company and the Bank. Under the 2016 Plan, the exercise price and vesting period for stock options are determined by the award committee and specified in the award agreement, however, the exercise price shall not be less than the fair market value of a share as of the grant date. Any unexercised stock option will expire 10 years after the award date or sooner in the event of the award recipient’s death, disability, retirement, or termination of service. The fair value of each option award is estimated on the grant date using a Black-Scholes model that uses the following assumptions. The dividend yield is based on the current quarterly dividend in effect at the time of the grant. Historical employment data is used to estimate the forfeiture rate. The historical volatility of the Company’s stock price over a specified period of time is used for the expected volatility assumption. First Financial Northwest bases the risk-free interest rate on the U.S. Treasury Constant Maturity Indices in effect on the date of the grant. First Financial Northwest elected to use the “Share-Based Payments” method permitted by the SEC to calculate the expected term. This method uses the vesting term of an option along with the contractual term, setting the expected life at the midpoint. Under certain conditions, a cashless exercise of vested stock options may occur by the option holder surrendering the number of options valued at the current stock price at the time of exercise to cover the total cost to exercise. The surrendered options are canceled and are unavailable for reissue. A summary of the Company’s stock option plan awards and activity for the three months ended March 31, 2021, follows: For the Three Months Ended March 31, 2021 Shares Weighted-Average Exercise Price Weighted-Average Remaining Contractual Term in Years Aggregate Intrinsic Value Weighted-Average Grant Date Fair Value Outstanding at January 1, 2021 313,000 $ 10.34 $ 397,890 $ 3.69 Exercised (2,000) 10.77 5,920 4.16 Outstanding at March 31, 2021 311,000 10.34 2.73 1,217,380 3.69 Expected to vest assuming a 3% forfeiture rate over the vesting term 311,000 10.34 2.73 1,217,380 3.69 Exercisable at March 31, 2021 311,000 10.34 2.73 1,217,380 3.69 As of March 31, 2021, there was no unrecognized compensation cost related to nonvested stock options. There were no stock options granted during the three months ended March 31, 2021. Restricted Stock Awards The 2016 Plan authorizes the grant of restricted stock awards subject to vesting periods or terms as defined by the award committee and specified in the award agreement. Restricted stock awards granted in lieu of cash payments for directors’ fees are subject to immediate vesting on the grant date unless the award agreement provides otherwise. A summary of changes in nonvested restricted stock awards for the three months ended March 31, 2021, follows: For the Three Months Ended March 31, 2021 Shares Weighted-Average Nonvested at January 1, 2021 16,228 $ 13.61 Granted 45,593 13.78 Vested (17,395) 13.62 Nonvested at March 31, 2021 44,426 13.78 Expected to vest assuming a 3% forfeiture rate over the vesting term 43,093 13.78 eleven

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Per the provisions of FASB ASC 260, Earnings Per Share , nonvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents are participating securities and are included in the computation of EPS pursuant to the two-class method. The two-class method is an earnings allocation formula that determines earnings per share for each class of common stock and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings. Certain of the Company’s nonvested restricted stock awards qualify as participating securities. Net income is allocated between the common stock and participating securities pursuant to the two-class method, based on their rights to receive dividends, participate in earnings, or absorb losses. Basic earnings per common shares is computed by dividing net earnings available to common shareholders by the weighted-average number of common shares outstanding during the period, excluding participating nonvested restricted shares. The following table presents a reconciliation of the components used to compute basic and diluted earnings per share for the periods indicated: Three Months Ended March 31, 2021 2020 (Dollars in thousands, except share data) Net income $ 2,497 $ 1,684 Less: Earnings allocated to participating securities (11) (3) Earnings allocated to common shareholders $ 2,486 $ 1,681 Basic weighted average common shares outstanding 9,490,058 9,896,234 Dilutive stock options 67,068 72,120 Dilutive restricted stock grants 9,545 9,706 Diluted weighted average common shares outstanding 9,566,671 9,978,060 Basic earnings per share $ 0.26 $ 0.17 Diluted earnings per share $ 0.26 $ 0.17

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition In accordance with Topic 606, revenues are recognized when goods or services are transferred to the customer in exchange for the consideration the Company expects to be entitled to receive. To determine the appropriate recognition of revenue for transactions within the scope of Topic 606, the Company performs the following five steps: (i) identify the contract(s) with the customer; (ii) identify the separate performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the separate performance obligations in the contract; and (v) recognize revenue when the entity satisfies a performance obligation. A contract may not exist if there are doubts as to collectability of the amounts the Company is entitled to in exchange for the goods or services transferred. If a contract is determined to be within the scope of Topic 606, the Company recognizes revenue as it satisfies a performance obligation. The largest portion of the Company’s revenue is from net interest income which is not within the scope of Topic 606. Disaggregation of Revenue The following table includes the Company’s noninterest income disaggregated by type of service for the three months ended March 31, 2021 and 2020: Three Months Ended March 31, 2021 March 31, 2020 (In thousands) BOLI change in cash surrender value (1) $ 269 $ 254 Wealth management revenue 160 165 Deposit related fees 66 68 Debit card and ATM fees 134 108 Loan related fees 132 392 Other 3 3 Total noninterest income $ 764 $ 990 _______________ (1) Not within scope of Topic 606 For the three months ended March 31, 2021 and 2020, substantially all of the Company’s revenues under the scope of Topic 606 are for performance obligations satisfied at a specified date. Revenues recognized within scope of Topic 606 Wealth management revenue: Our wealth management revenue consists of commissions received on the investment portfolio managed by Bank personnel but held by a third party. Commissions are earned on brokerage services and advisory services based on contract terms at the onset of a new customer’s investment agreement or quarterly for ongoing services. Commissions are paid by the third party to the Bank when the performance obligation has been completed by both entities. Deposit related fees: Fees are earned on our deposit accounts for various products or services performed for our customers. Fees include business account fees, non-sufficient fund fees, stop payment fees, wire services, safe deposit box, and others. These fees are recognized on a daily or monthly basis, depending on the type of service. Debit card and ATM fees: Fees are earned when a debit card issued by the Bank is used or when other bank’s customers use our ATM services. Revenue is recognized at the time the fees are collected from the customer’s account or remitted by the VISA interchange network. Loan related fees: Noninterest fee income is earned on our loans for servicing or annual fees on certain loan types. Fees are also earned on the prepayment of certain loans, and are recognized at the time the loan is paid off. Other: Fees earned on other services, such as merchant services or occasional non-recurring type services, are recognized at the time of the event or the applicable billing cycle. Contract Balances

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recently Issued Accounting Pronouncements	Recent Accounting Pronouncements Adopted in 2021 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 (i) 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; (ii) the requirement to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment, and (iii) the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The Company adopted this ASU in January 2021 with no material impact on its consolidated financial statements. In October 2020, the FASB issued 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. The Company adopted this ASU in January 2021 with no material impact on its consolidated financial statements. Recent Accounting Pronouncements ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) as amended by ASU 2018-19, ASU 2019-04 and ASU 2019-05, was originally issued in June 2016 .
