Accounting Policies [Abstract]
Description of Business	Description of Business First Financial Northwest, Inc. (“First Financial Northwest”), a Washington corporation, was formed on June 1, 2007 for the purpose of becoming the holding company for First Financial Northwest Bank (the “Bank”) in connection with the conversion from a mutual holding company structure to a stock holding company structure which was completed on October 9, 2007. First Financial Northwest’s business activities generally are limited to passive investment activities and oversight of its investment in the Bank. Accordingly, the information presented in the consolidated financial statements and accompanying data, relates primarily to the Bank. First Financial Northwest is a bank holding company, having converted from a savings and loan holding company on March 31, 2015, and as a bank holding company is subject to regulation by the Federal Reserve Bank of San Francisco (“FRB”). The Bank is regulated by the Federal Deposit Insurance Corporation (“FDIC”) and the Washington State Department of Financial Institutions (“DFI”). At September 30, 2023, the Bank operated in 15 locations in Washington with the headquarters and seven retail branch locations in King County, five retail branch locations in Snohomish County and two retail branches in Pierce County. The Bank’s primary market area consists of King, Snohomish, Pierce and Kitsap counties, Washington. 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. Loans are primarily funded by deposits from the general public, supplemented by borrowings from the FHLB and deposits raised in the national brokered deposit market. As used throughout this report, the terms “we,” “our,” “us,” or the “Company” refer to First Financial Northwest, Inc. and its consolidated subsidiary First Financial Northwest Bank, unless the context otherwise requires.

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, 2022, as filed with the SEC (“2022 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 nine months ended September 30, 2023, are not necessarily indicative of the results that may be expected for the year ending December 31, 2023. 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 credit losses (“ACL”), the valuation of other real estate owned (“OREO”) and the underlying collateral of individually analyzed 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.

Accounting Policies [Abstract]
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Recent Accounting Pronouncements Accounting Standards Update (“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 by the Financial Accounting Standards Board (“FASB”) in June 2016 . This ASU replaces the incurred loss methodology that delays recognition until it is probable a loss has been incurred with an expected loss methodology that is referred to as the current expected credit loss (“CECL”) methodology. 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 measurement of expected credit losses will be based on historical information, current conditions, and reasonable and supportable forecasts that impact the collectability of the reported amount. Available-for-sale securities will bifurcate the fair value mark and establish an allowance for credit losses through the income statement for the credit portion of that mark. The interest portion will continue to be recognized through accumulated other comprehensive income or loss. 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. This ASU was effective for smaller reporting companies, such as the Company, on January 1, 2023. ASU 2019-05 issued in April 2019 further provides that entities that have certain financial instruments measured at amortized cost that have credit losses, to irrevocably elect the fair value option in Subtopic 825-10, upon adoption of Topic 326. The fair value option applies to available-for-sale debt securities. This ASU was effective upon adoption of ASU 2016-13, and should be applied on a modified-retrospective basis as a cumulative-effect adjustment to the opening balance of retained earnings in the statement of financial condition as of the adoption date. On January 1, 2023, the Company adopted this ASU, which resulted in a net of tax charge of $395,000 to retained earnings, and a $500,000 increase to allowance for credit losses for the cumulative effect of adopting this guidance. The impact that the transition to CECL had on the expected credit losses on unfunded commitments was deemed to be immaterial. In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848) . This ASU applies to contracts, hedging relationships and other transactions that reference London Interbank Offering Rate (“LIBOR”) or other rate references expected to be discontinued because of reference rate reform. The amendments in this ASU are elective and apply to all entities that have derivative instruments that use an interest rate that will be modified by reference rate reform. This ASU provides implementation guidance to clarify that certain optional expedients and exceptions in Topic 848 may be applied to derivative instruments. This ASU may be elected on a full retrospective basis for any interim period subsequent to March 12, 2020, or on a prospective basis to new modifications from any date subsequent to the date of issuance. Effective January 25, 2021, the Company adhered to the Interbank Offered Rate Fallbacks Protocol (“Protocol”) as published by the International Swaps and Derivatives Association, Inc. and recommended by the Alternative Reference Rates Committee. Additionally, effective January 1, 2022, the Company was no longer initiating or renewing loans using LIBOR as an index. The Company holds derivative instruments that use LIBOR as the reference rate that were impacted by the discontinuance of LIBOR on June 30, 2023. As of September 30, 2023, the Company’s derivative instruments’ variable-rate interest payments have been converted to be based on Secured Overnight Financing Rate (“SOFR”). In March 2022, the FASB issued ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures . This ASU eliminates the accounting guidance for troubled debt restructured loans (“TDRs”) by creditors while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Additionally, the ASU requires public business entities to disclose current-period gross charge-offs by year of origination for financing receivables and net investments in leases. This ASU is effective upon adoption of ASU 2016-13. On January 1, 2023, the Company adopted this ASU at the same time ASU 2016-13 was adopted. The Company had no loans modified for borrowers experiencing financial difficulty during the nine months ended September 30, 2023.

On a quarterly basis, management evaluates impaired debt securities to determine if an allowance for credit losses is required. If it is determined that a credit loss exists and an allowance is required, the credit loss on a debt security is measured as the difference between the amortized cost and the present value of the cash flows expected to be collected, limited by the amount of the impairment. For impaired debt securities that the Company does not intend to sell and it is not likely that it will be required to sell but does not expect to recover the entire security’s amortized cost basis, only the portion of the impairment representing a credit loss would be recognized in earnings. 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 would be recognized through earnings. The Company considers many factors including the severity and duration of the impairment, economic circumstances, recent events specific to the issuer or industry, and for debt securities, external credit ratings and recent rating updates. Projected cash flows are discounted by the original or current effective interest rate depending on the nature of the debt security being measured for a potential credit loss. The remaining impairment related to all other factors is recognized as a charge to other comprehensive income (“OCI”). The Company had 131 securities and 123 securities in an unrealized loss position, with 114 and 62 of these securities in an unrealized loss position for 12 months or more, at September 30, 2023, and December 31, 2022, respectively. Management does not believe that the unrealized losses at September 30, 2023 and December 31, 2022 were related to credit losses. The declines in fair market value of these securities were mainly attributed to changes in market interest rates, credit spreads, market volatility and liquidity conditions. Currently, the Company does not intend to sell, and it is not more likely than not that the Company will be required to sell the positions before their recovery of the amortized cost basis, which may be at maturity. As such, no allowance for credit losses was recorded with respect to AFS securities for the three and nine months ended September 30, 2023. The amortized cost and estimated fair value of investments available-for-sale at September 30, 2023, 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.

Investment securities with market values of $26.0 million and $21.0 million were pledged as collateral for public deposits at September 30, 2023, and December 31, 2022, respectively, both of which exceeded the collateral requirements established by the Washington Public Deposit Protection Commission. For the three and nine months ended September 30, 2023, there were no calls, sales or maturities of investment securities. For the three and nine months ended September 30, 2022, there were $399,000 and $3.8 million, respectively, in calls and maturities on investment securities with no gain or loss generated. 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 September 30, 2023, the annuities were reported as investments held-to-maturity at an amortized cost of $2.5 million on the Company’s Consolidated Balance Sheets. The amortized cost is considered the fair value of the investment.

At September 30, 2023, loans totaling $655.7 million were pledged to secure borrowings from the FHLB compared to $605.0 million at December 31, 2022. In addition, loans totaling $81.1 million and $87.7 million were pledged to FRB to secure a line of credit at September 30, 2023 and December 31, 2022, 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 identify 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 Company. 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. The grades for watch and special mention loans are used by the Company to identify and track potential problem loans which do not rise to the levels described for substandard, doubtful, or loss. These are loans which have been criticized 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. Management considers the guidance in Accounting Standards Codification (“ASC”) 310-20 when determining whether a modification, extension, or renewal of loan constitutes a current period origination. As of September 30, 2023, and December 31, 2022, the Company had no loans rated as doubtful or loss. The following tables represent a summary of loans at September 30, 2023, and December 31, 2022 by type and risk category: September 30, 2023 Term Loans by Year of Origination 2023 2022 2021 2020 2019 Prior Total Loans (In thousands) One-to-four family residential Pass $ 56,489 $ 147,961 $ 95,279 $ 63,685 $ 32,015 $ 96,667 $ 492,096 Watch — — — — — 711 711 Special mention — — — — — 401 401 Substandard — — — — — — — Total one-to-four family residential $ 56,489 $ 147,961 $ 95,279 $ 63,685 $ 32,015 $ 97,779 $ 493,208 Current year-to-date (“YTD”) gross charge-offs $ — $ — $ — $ — $ — $ — $ — Multifamily Pass $ 3,335 $ 8,363 $ 22,892 $ 43,492 $ 26,079 $ 32,003 $ 136,164 Watch — — — — — 2,257 2,257 Special mention — — — — — — — Substandard — — — — — 1,601 1,601 Total multifamily $ 3,335 $ 8,363 $ 22,892 $ 43,492 $ 26,079 $ 35,861 $ 140,022 Current YTD gross charge-offs $ — $ — $ — $ — $ — $ — $ — (Continued) September 30, 2023 Term Loans by Year of Origination 2023 2022 2021 2020 2019 Prior Total Loans (In thousands) Commercial Pass $ 19,548 $ 35,248 $ 81,622 $ 78,694 $ 21,206 $ 106,640 $ 342,958 Watch — — 4,134 — — 3,350 7,484 Special mention — — — — — — — Substandard — — — 527 1,295 42,427 44,249 Total commercial real estate $ 19,548 $ 35,248 $ 85,756 $ 79,221 $ 22,501 $ 152,417 $ 394,691 Current YTD gross charge-offs $ — $ — $ — $ — $ — $ — $ — Construction/land Pass $ 6,786 $ 28,395 $ 20,160 $ — $ — $ — $ 55,341 Watch — — — — — — — Special mention — — — — — — — Substandard — — — — — — — Total construction/land $ 6,786 $ 28,395 $ 20,160 $ — $ — $ — $ 55,341 Current YTD gross charge-offs $ — $ — $ — $ — $ — $ — $ — Business Pass $ 1,463 $ 4,525 $ 410 $ 1,385 $ 1,676 $ 18,516 $ 27,975 Watch — — — — — — — Special mention — — — — — — — Substandard — — — — — — — Total business $ 1,463 $ 4,525 $ 410 $ 1,385 $ 1,676 $ 18,516 $ 27,975 Current YTD gross charge-offs $ — $ — $ — $ — $ — $ — $ — Consumer Pass $ 21,630 $ 25,371 $ 11,273 $ 5,747 $ 5,073 $ 2,825 $ 71,919 Watch — 28 — — — 28 Special mention — — — — — — — Substandard — — 201 — — — 201 Total consumer $ 21,630 $ 25,399 $ 11,474 $ 5,747 $ 5,073 $ 2,825 $ 72,148 Current YTD gross charge-offs $ — $ — $ — $ — $ 22 $ — $ 22 Total loans receivable, gross Pass $ 109,251 $ 249,863 $ 231,636 $ 193,003 $ 86,049 $ 256,651 $ 1,126,453 Watch — 28 4,134 — — 6,318 10,480 Special mention — — — — — 401 401 Substandard — — 201 527 1,295 44,028 46,051 Total loans $ 109,251 $ 249,891 $ 235,971 $ 193,530 $ 87,344 $ 307,398 $ 1,183,385 Current YTD gross charge-offs $ — $ — $ — $ — $ 22 $ — $ 22 December 31, 2022 One-to-Four Multifamily Commercial Construction/ Business Consumer Total (1) (In thousands) Risk Rating: Pass, grade 1-4 $ 473,700 $ 122,972 $ 342,827 $ 78,120 $ 31,371 $ 61,632 $ 1,110,622 Pass, grade 5 (watch) 1,113 2,291 14,845 — — 27 18,276 Special mention 1,023 — 4,668 — — 203 5,894 Substandard — 1,632 45,542 — — 193 47,367 Total loans $ 475,836 $ 126,895 $ 407,882 $ 78,120 $ 31,371 $ 62,055 $ 1,182,159 (1) Deferred loan fees (costs) of $151,000 were excluded. ACL . ACL is a valuation account that is deducted from the loans amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged off against the ACL when management believes the non-collectability of a loan balance is confirmed. Expected recoveries may not exceed the aggregate amounts previously charged-off and expected to be charged-off. The ACL, as reported in our consolidated balance sheets, is adjusted by a provision for credit losses, which is reported in earnings, and reduced by the charge-offs of loan amounts, net of recoveries. 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 Company will be able to collect all amounts due according to the contractual terms of the loan, it may establish a specific allowance 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 allowance is subject to review by bank regulators, who can require the establishment of additional allowances for credit losses. At September 30, 2023, total loans receivable included $551,000 of loans originated under the Small Business Administration (“SBA”) Paycheck Protection Program (“PPP”) compared to $784,000 at December 31, 2022. Although these loans were included in the population of loans collectively evaluated for impairment, no general allowance was allocated to them as these loans are 100% guaranteed by the SBA.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value The Company measures the fair value of financial instruments for reporting in accordance with 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, is 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. • Loans individually evaluated: The fair value of individually evaluated loans is based on an analysis utilizing expected cash flows discounted using the original effective interest rate, the observable market price of the loan, or the fair value of the collateral, less selling costs, for collateral-dependent loans as appropriate. • 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 judgement or estimation.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives The Company uses derivative financial instruments, in particular, interest rate swaps, which are designated as cash flow hedges, to manage the risk of changes in future cash flows due to interest rate fluctuations. At September 30, 2023, the hedged cash flows had a total notional amount of $125.0 million and consisted of rolling one-month or three-month FHLB advances that renew at the fixed interest rate at each renewal date. These hedging instruments have two Quarterly, the effectiveness evaluation is based upon the fluctuation of the fixed rate interest the Company pays to the FHLB for the period compared to the one-month or three-month SOFR-based interest received from the counterparty. At September 30, 2023, a $10.7 million net fair value gain of the cash flow hedges was reported with other assets on the Company’s Consolidated Balance Sheet. The tax effected amount of $8.5 million was included in accumulated other comprehensive loss on the Company’s Consolidated Balance Sheet. There were no amounts recorded on the Consolidated Income Statements for the three and nine months ended September 30, 2023 or 2022, 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.

Stock-Based Compensation

Stock-Based Compensation	9 Months Ended

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, non-qualified stock options, 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. As a result of the approval of the 2016 Plan, the First Financial Northwest, Inc. 2008 Equity Incentive Plan (“2008 Plan”) was frozen with no additional awards being made under the 2008 Plan. Restricted stock awards and stock options that were granted under the 2008 Plan are fully vested and unexercised options remain exercisable, subject to the provision of the 2008 Plan and the respective award agreements. At September 30, 2023, there were 848,598 total shares available for grant under the 2016 Plan, including 144,299 shares available to be granted as restricted stock. 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. For the three months ended September 30, 2023 and 2022, total compensation expense for awards granted under the 2016 Plan was $270,000 and $327,000, respectively, and the related income tax benefit was $57,000 and $69,000, respectively. For the nine months ended September 30, 2023 and 2022, total compensation expense for awards granted under the 2016 Plan was $497,000 and $641,000, respectively, and the related income tax benefit was $104,000 and $135,000 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. At September 30, 2023, there were 122,500 stock options from the 2008 Plan vested and available for exercise, subject to the 2008 Plan provisions. 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. At September 30, 2023, there were 40,000 stock options granted from the 2016 Plan. 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. The Company’s stock option plan awards and activity for the three and nine months ended September 30, 2023 are summarized as follows: For the Three Months Ended September 30, 2023 Shares Weighted-Average Exercise Price Weighted-Average Remaining Contractual Term in Years Aggregate Intrinsic Value Weighted-Average Grant Date Fair Value Outstanding at July 1, 2023 217,519 $ 11.20 $ 104,584 $ 4.10 Granted 40,000 12.06 — 2.98 Exercised (95,019) 10.78 114,438 3.85 Outstanding at September 30, 2023 162,500 11.65 3.40 186,025 3.98 Vested and expected to vest assuming a 3% forfeiture rate over the vesting term 161,300 11.65 3.35 185,233 3.99 Exercisable at September 30, 2023 122,500 11.52 1.30 159,625 4.30 For the Nine Months Ended September 30, 2023 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, 2023 217,519 $ 11.20 $ 823,028 $ 4.10 Granted 40,000 12.06 — 2.98 Exercised (95,019) 10.78 114,438 3.85 Outstanding at September 30, 2023 162,500 11.65 3.40 186,025 3.98 Vested and expected to vest assuming a 3% forfeiture rate over the vesting term 161,300 11.65 3.35 185,233 3.99 Exercisable at September 30, 2023 122,500 11.52 1.30 159,625 4.30 As of September 30, 2023, there was $111,140 of total unrecognized compensation cost related to nonvested stock options. The cost is expected to be recognized over the remaining weighted-average vesting period of 3.8 years. There were 40,000 stock options granted during the nine months ended September 30, 2023. 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.

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 share 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 September 30, Nine Months Ended September 30, 2023 2022 2023 2022 (Dollars in thousands, except per share data) Net income $ 1,501 $ 3,946 $ 5,111 $ 10,014 Less: Earnings allocated to participating securities (4) (13) (15) (33) Earnings allocated to common shareholders $ 1,497 $ 3,933 $ 5,096 $ 9,981 Basic weighted average common shares outstanding 9,127,568 8,981,037 9,117,554 8,983,806 Dilutive stock options 13,991 75,195 23,069 90,608 Dilutive restricted stock grants 8,500 12,309 6,086 13,792 Diluted weighted average common shares outstanding 9,150,059 9,068,541 9,146,709 9,088,206 Basic earnings per share $ 0.16 $ 0.44 $ 0.56 $ 1.11 Diluted earnings per share $ 0.16 $ 0.43 $ 0.56 $ 1.10

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 and nine months ended September 30, 2023 and 2022: Three Months Ended September 30, Nine Months Ended September 30, 2023 2022 2023 2022 (In thousands) BOLI change in cash surrender value (1) $ 244 $ 243 $ 826 $ 782 Wealth management revenue 53 89 193 276 Deposit related fees 85 79 246 237 Debit card and ATM fees 162 166 476 468 Loan related fees 79 195 215 748 Other 54 6 184 17 Total noninterest income $ 677 $ 778 $ 2,140 $ 2,528 _______________ (1) Not within scope of Topic 606 For both the three and nine months ended September 30, 2023 and 2022, 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 Company when the performance obligation has been completed by both entities. Deposit related fees: Fees are earned on deposit accounts for various products or services performed for the Company’s 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 Company is used or when another financial institution’s customer uses the Company’s 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 loans for servicing or annual fees earned 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. Also included is income relating to our investment in a Fintech Focused Fund. Contract Balances

Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Standards Update (“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 by the Financial Accounting Standards Board (“FASB”) in June 2016 . This ASU replaces the incurred loss methodology that delays recognition until it is probable a loss has been incurred with an expected loss methodology that is referred to as the current expected credit loss (“CECL”) methodology. 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 measurement of expected credit losses will be based on historical information, current conditions, and reasonable and supportable forecasts that impact the collectability of the reported amount. Available-for-sale securities will bifurcate the fair value mark and establish an allowance for credit losses through the income statement for the credit portion of that mark. The interest portion will continue to be recognized through accumulated other comprehensive income or loss. 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. This ASU was effective for smaller reporting companies, such as the Company, on January 1, 2023. ASU 2019-05 issued in April 2019 further provides that entities that have certain financial instruments measured at amortized cost that have credit losses, to irrevocably elect the fair value option in Subtopic 825-10, upon adoption of Topic 326. The fair value option applies to available-for-sale debt securities. This ASU was effective upon adoption of ASU 2016-13, and should be applied on a modified-retrospective basis as a cumulative-effect adjustment to the opening balance of retained earnings in the statement of financial condition as of the adoption date. On January 1, 2023, the Company adopted this ASU, which resulted in a net of tax charge of $395,000 to retained earnings, and a $500,000 increase to allowance for credit losses for the cumulative effect of adopting this guidance. The impact that the transition to CECL had on the expected credit losses on unfunded commitments was deemed to be immaterial. In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848) . This ASU applies to contracts, hedging relationships and other transactions that reference London Interbank Offering Rate (“LIBOR”) or other rate references expected to be discontinued because of reference rate reform. The amendments in this ASU are elective and apply to all entities that have derivative instruments that use an interest rate that will be modified by reference rate reform. This ASU provides implementation guidance to clarify that certain optional expedients and exceptions in Topic 848 may be applied to derivative instruments. This ASU may be elected on a full retrospective basis for any interim period subsequent to March 12, 2020, or on a prospective basis to new modifications from any date subsequent to the date of issuance. Effective January 25, 2021, the Company adhered to the Interbank Offered Rate Fallbacks Protocol (“Protocol”) as published by the International Swaps and Derivatives Association, Inc. and recommended by the Alternative Reference Rates Committee. Additionally, effective January 1, 2022, the Company was no longer initiating or renewing loans using LIBOR as an index. The Company holds derivative instruments that use LIBOR as the reference rate that were impacted by the discontinuance of LIBOR on June 30, 2023. As of September 30, 2023, the Company’s derivative instruments’ variable-rate interest payments have been converted to be based on Secured Overnight Financing Rate (“SOFR”). In March 2022, the FASB issued ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures . This ASU eliminates the accounting guidance for troubled debt restructured loans (“TDRs”) by creditors while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Additionally, the ASU requires public business entities to disclose current-period gross charge-offs by year of origination for financing receivables and net investments in leases. This ASU is effective upon adoption of ASU 2016-13. On January 1, 2023, the Company adopted this ASU at the same time ASU 2016-13 was adopted. The Company had no loans modified for borrowers experiencing financial difficulty during the nine months ended September 30, 2023. The Company had a $22,000 gross charge-off in consumer loans since the adoption of this ASU and the write off was included in the table with the summary of loans by type and risk category at September 30, 2023, in Note 5.
