Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Nature of operations - First Northwest Bancorp, a Washington corporation ("First Northwest"), became the holding company of First Federal Savings and Loan Association of Port Angeles ("First Federal" or the "Bank") on January 29, 2015 , upon completion of the Bank's conversion from a mutual to stock form of organization (the "Conversion"). First Northwest and the Bank are collectively referred to as the "Company." In connection with the Conversion, the Company issued an aggregate of 12,167,000 shares of common stock at an offering price of $10.00 per share for gross proceeds of $121.7 million . An additional 933,360 shares of Company common stock and $400,000 in cash were contributed to the First Federal Community Foundation ("Foundation"), a charitable foundation that was established in connection with the conversion, resulting in the issuance of a total of 13,100,360 shares. The Company received $117.6 million in net proceeds from the stock offering of which $58.4 million were contributed to the Bank upon Conversion. At the time of Conversion, the Bank established a liquidation account in an amount equal to its total net worth, approximately $79.7 million , as of June 30, 2014, the latest statement of financial condition appearing in First Northwest's prospectus. The liquidation account is maintained for the benefit of eligible depositors who continue to maintain their accounts at the Bank after the conversion. The liquidation account is reduced annually to the extent that eligible depositors have reduced their qualifying deposits. Subsequent increases will not restore an eligible holder’s interest in the liquidation account. In the event of a complete liquidation, each eligible depositor will be entitled to receive a distribution from the liquidation account in an amount proportionate to the current adjusted qualifying balances for accounts then held. The liquidation account balance is not available for payment of dividends, and the Bank may not pay dividends if those dividends would reduce equity capital below the required liquidation account amount. Pursuant to the Plan of Conversion, the Bank’s Board of Directors adopted an ESOP which purchased in the open market 8% of the common stock originally issued for a total of 1,048,029 shares. As of December 15, 2015 , 1,048,029 shares, or 100.0% of the total, had been purchased. As of December 31, 2018 , First Northwest had allocated 201,026 shares from the total shares purchased to participants. First Northwest's business activities generally are limited to passive investment activities and oversight of its investment in First Federal. Accordingly, the information set forth in this report, including the consolidated financial statements and related data, relates primarily to the Bank. The Bank is a community-oriented financial institution providing commercial and consumer banking services to individuals and businesses in Western Washington State with offices in Clallam, Jefferson, Kitsap, and Whatcom counties. These services include deposit and lending transactions that are supplemented with borrowing and investing activities. Change in Fiscal Year - The Company's Board of Directors approved a change in the Company's fiscal year end from June 30 to December 31, effective December 31, 2017. As a result of this change, the consolidated financial statements include the Company's financial results for the six month transition period from July 1, 2017 to December 31, 2017. The following tables present certain comparative transition period condensed financial information for both the twelve months ended and six months ended December 31, 2018, 2017, and 2016, respectively. For the Six Months Ended December 31, 2017 2016 (Unaudited) Interest income $ 20,286 $ 17,460 Interest expense 3,293 2,441 Net interest income 16,993 15,019 Provision for loan losses 200 760 Net interest income after provision for loan losses 16,793 14,259 Noninterest income 3,055 2,773 Noninterest expense 16,147 14,340 Income before provision for income taxes 3,701 2,692 Provision for income taxes 2,042 853 Net income $ 1,659 $ 1,839 Basic and diluted earnings per share $ 0.16 $ 0.16 Basic weighted average common shares outstanding 10,606,798 11,409,649 Diluted weighted average common shares outstanding 10,703,081 11,452,017 For the Six Months Ended December 31, 2017 2016 (Unaudited) Net cash from operating activities $ 4,959 $ (4,338 ) Net cash from investing activities (117,987 ) (39,392 ) Net cash from financing activities 125,537 43,729 Net increase (decrease) in cash and cash equivalents 12,509 (1 ) Cash and cash equivalents, beginning of period 24,292 22,650 Cash and cash equivalents, end of period $ 36,801 $ 22,649 Supplemental Disclosure of Cash Flow Information Cash paid during the period for: Interest on deposits and borrowings $ 3,176 $ 2,426 Income taxes 661 1,661 Use of estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make assumptions. These assumptions result in estimates that affect the reported amounts of assets and liabilities, revenues and expenses, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to a determination of the allowance for loan losses, fair value of financial instruments, deferred tax assets and liabilities, and the valuation of impaired loans. Principles of consolidation - The accompanying consolidated financial statements include the accounts of First Northwest Bancorp and its wholly owned subsidiary, First Federal. All material intercompany accounts and transactions have been eliminated in consolidation. Subsequent events - The Company has evaluated subsequent events for potential recognition and disclosure and determined there are no such events or transactions requiring recognition or disclosure. Cash and cash equivalents - Cash and cash equivalents consist of currency on hand, due from banks, and interest-bearing deposits with financial institutions with an original maturity of three months or less. The amounts on deposit fluctuate and, at times, exceed the insured limit by the FDIC, which potentially subjects First Federal to credit risk. First Federal has not experienced any losses due to balances exceeding FDIC insurance limits. Restricted assets - Federal Reserve Board regulations require maintenance of certain minimum reserve balances on deposit with the Federal Reserve Bank of San Francisco. The amount required to be on deposit was approximately $9.1 million , $10.1 million and $8.8 million at December 31, 2018 , December 31, 2017 and June 30, 2017 , respectively. First Federal was in compliance with its reserve requirements at December 31, 2018 , December 31, 2017 and June 30, 2017 . Investment securities - Investment securities are classified into one of three categories: (1) held-to-maturity, (2) available-for-sale, or (3) trading. First Federal had no trading securities at December 31, 2018 , December 31, 2017 and June 30, 2017 . Investment securities are categorized as held-to-maturity when First Federal has the positive intent and ability to hold those securities to maturity. Securities that are held-to-maturity are stated at cost and adjusted for amortization of premiums and accretion of discounts, which are recognized as adjustments to interest income. Investment securities categorized as available for sale are generally held for investment purposes (to maturity), although unanticipated future events may result in the sale of some securities. Available-for-sale securities are recorded at fair value, with the unrealized holding gain or loss reported in other comprehensive income (OCI), net of tax, as a separate component of shareholders' equity. Realized gains or losses are determined using the amortized cost basis of securities sold using the specific identification method and are included in earnings. Dividend and interest income on investments are recognized when earned. Premiums and discounts are recognized in interest income using the level yield method over the period to maturity. The Company reviews investment securities for other-than-temporary impairment (OTTI) on a quarterly basis. For debt securities, the Company considers whether management intends to sell a security or if it is likely that the Company will be required to sell the security before recovery of the amortized cost basis of the investment, which may be maturity. For debt securities, if management intends to sell the security or it is likely that the Company will be required to sell the security before recovering its cost basis, the entire impairment loss would be recognized as OTTI and charged against earnings. If management does not intend to sell the security and it is not likely that the Company will be required to sell the security, but management does not expect to recover the entire amortized cost basis of the security, only the portion of the impairment loss representing credit losses would be recognized in earnings. The credit loss on a 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 security being measured for potential OTTI. The remaining impairment related to all other factors, i.e. the difference between the present value of the cash flows expected to be collected and fair value, is recognized as a charge to OCI. Impairment losses related to all other factors are presented as separate categories within OCI. If there is an indication of additional credit losses, the security is re-evaluated according to the procedures described above. Federal Home Loan Bank stock - First Federal’s investment in Federal Home Loan Bank of Des Moines (FHLB) stock is carried at cost, which approximates fair value. As a member of the FHLB system, First Federal is required to maintain a minimum investment in FHLB stock based on specific percentages of its outstanding mortgages, total assets, or FHLB advances. At December 31, 2018 and 2017 , First Federal’s minimum investment requirement was approximately $6.9 million and $7.0 million , respectively. First Federal was in compliance with the FHLB minimum investment requirement at December 31, 2018 and 2017 . First Federal may request redemption at par value of any stock in excess of the amount First Federal is required to hold. Stock redemptions are granted at the discretion of the FHLB. Management evaluates FHLB stock for impairment based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) the significance of any decline in net assets of the FHLB compared with the capital stock amount for the FHLB and the length of time this situation has persisted, (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB, (3) the impact of legislative and regulatory changes on institutions and, accordingly, the customer base of the FHLB, and (4) the liquidity position of the FHLB. Based on its evaluation, First Federal did not recognize an OTTI loss on its FHLB stock at December 31, 2018 and 2017 . Loans held for sale - Mortgage loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or fair value. Fair value is determined based upon market prices from third-party purchasers and brokers. Net unrealized losses, if any, are recognized through a valuation allowance by charges to earnings. Gains or losses on the sale of loans are recognized at the time of sale and determined by the difference between net sale proceeds and the net book value of the loan less the estimated fair value of any retained mortgage servicing rights. Loans receivable - Loans are stated at the amount of unpaid principal, net of charge-offs, unearned income, allowance for loan loss (ALLL) and any deferred fees or costs. Interest on loans is calculated using the simple interest method based on the month end balance of the principal amount outstanding and is credited to income as earned. The estimated life is adjusted for prepayments. Each loan segment and class inherently contains differing credit risk profiles depending on the unique aspects of that segment or class of loans. For example, borrowers tend to consider their primary residence and access to transportation for employment-related purposes as basic requirements; accordingly, many consumers prioritize making payments on real estate first-mortgage loans and vehicle loans. Conversely, second-mortgage real estate loans or unsecured loans may not be supported by sufficient collateral; thus, in the event of financial hardship, borrowers may tend to place less importance on maintaining these loans as current and the Bank may not have adequate collateral to provide a secondary source of repayment in the event of default. Notwithstanding the various risk profiles unique to each class of loan, management believes that the credit risk for all loans is similarly dependent on essentially the same factors, including the financial strength of the borrower, the cash flow available to service maturing debt obligations, the condition and value of underlying collateral, the financial strength of any guarantors, and other factors. Loans are classified as impaired when, based on current information and events, it is probable that First Federal will be unable to collect the scheduled payments of principal and interest when due, in accordance with the terms of the original loan agreement. The carrying value of impaired loans is based on the present value of expected future cash flows discounted at each loan’s effective interest rate or, for collateral dependent loans, at fair value of the collateral, less selling costs. If the measurement of each impaired loan’s value is less than the recorded investment in the loan, First Federal recognizes this impairment and adjusts the carrying value of the loan to fair value through the allowance for loan losses. This can be accomplished by charging off the impaired portion of the loan or establishing a specific component to be provided for in the allowance for loan losses. The accrual of interest on loans is discontinued at the time the loan is 90 days delinquent, unless the credit is well secured and in process of collection. In all cases, loans are placed on nonaccrual or charged off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not collected for loans that are placed on nonaccrual or charged off is reversed against interest income. The interest on these loans is accounted for on the cash basis or cost recovery method until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. For those loans placed on non-accrual status due to payment delinquency, return to accrual status will generally not occur until the borrower demonstrates repayment ability over a period of not less than six months. Loan fees - Loan origination fees and certain direct origination costs are deferred and amortized as an adjustment to the yield of the loan over the contractual life using the effective interest method. In the event a loan is sold, the remaining deferred loan origination fees and/or costs are recognized as a component of gains or losses on the sale of loans. Allowance for loan losses - First Federal maintains a general allowance for loan losses based on evaluating known and inherent risks in the loan portfolio, including management’s continuing analysis of the factors underlying the quality of the loan portfolio. These factors include changes in the size and composition of the loan portfolio, actual loan loss experience, and current and anticipated economic conditions. The reserve is an estimate based upon factors and trends identified by management at the time the financial statements are prepared. The ultimate recovery of loans is susceptible to future market factors beyond First Federal’s control, which may result in losses or recoveries differing significantly from those provided in the consolidated financial statements. In addition, various regulatory agencies, as an integral part of their examination processes, periodically review First Federal’s allowance for loan losses. Such agencies may require First Federal to recognize additional provisions for loan losses based on their judgment using information available to them at the time of their examination. Allowances for losses on specific problem loans are charged to income when it is determined that the value of these loans and properties, in the judgment of management, is impaired. First Federal accounts for impaired loans in accordance with Accounting Standards Codification (ASC) 310-10-35, Receivables—Overall—Subsequent Measurement . A loan is considered impaired when, based on current information and events, it is probable that First Federal will be unable to collect all amounts due according to the contractual terms of the loan agreement. When a loan has been identified as being impaired, the amount of the impairment is measured by using discounted cash flows, except when it is determined that the sole source of repayment for the loan is the operation or liquidation of the underlying collateral. In such cases, impairment is measured at current fair value generally based on a current appraisal of the collateral, reduced by estimated selling costs. When the measurement of the impaired loan is less than the recorded investment in the loan (including collected interest that has been applied to principal, net deferred loan fees or costs, and unamortized premiums or discounts), loan impairment is recognized by establishing or adjusting an allocation of the allowance for loan losses. Uncollected accrued interest is reversed against interest income. If ultimate collection of principal is in doubt, all cash receipts on impaired loans are applied to reduce the principal balance. The impairment amount for small balance homogeneous loans is calculated using the adjusted historical loss rate for the class and risk category related to each loan, unless the loan is subject to a troubled debt restructuring ("TDR"). A TDR is a loan for which First Federal, for reasons related to the borrower’s financial difficulties, grants a concession to the borrower that First Federal would not otherwise consider. The loan terms that have been modified or restructured due to the borrower’s financial difficulty include, but are not limited to, a reduction in the stated interest rate; an extension of the maturity; an interest rate below market; a reduction in the face amount of the debt; a reduction in the accrued interest; or extension, deferral, renewal, or rewrite of the original loan terms. The restructured loans may be classified “special mention” or “substandard” depending on the severity of the modification. Loans that were paid current at the time of modification may be upgraded in their classification after a sustained period of repayment performance, usually six months or longer, and there is reasonable assurance that repayment will continue. Loans that are past due at the time of modification are classified “substandard” and placed on nonaccrual status. TDR loans may be upgraded in their classification and placed on accrual status once there is a sustained period of repayment performance, usually six months or longer, and there is a reasonable assurance that repayment will continue. First Federal allows reclassification of a troubled debt restructuring back into the general loan pool (as a non-troubled debt restructuring) if the borrower is able to refinance the loan at then-current market rates and meet all of the underwriting criteria of First Federal required of other borrowers. The refinance must be based on the borrower’s ability to repay the debt and no special concessions of rate and/or term are granted to the borrower. Reserve for unfunded commitments - Management maintains a reserve for unfunded commitments to absorb probable losses associated with off-balance sheet commitments to lend funds such as unused lines of credit and the undisbursed portion of construction loans. Management determines the adequacy of the reserve based on reviews of individual exposures, current economic conditions, and other relevant factors. The reserve is based on estimates and ultimate losses may vary from the current estimates. The reserve is evaluated on a regular basis and necessary adjustments are reported in earnings during the period in which they become known. The reserve for unfunded commitments is included in "Accrued expenses and other liabilities" on the consolidated balance sheets. Real estate owned and repossessed assets - Real estate owned and repossessed assets include real estate and personal property acquired through foreclosure or repossession, and may include in-substance foreclosed properties. In-substance foreclosed properties are those properties for which the Bank has taken physical possession, regardless of whether formal foreclosure proceedings have taken place. Mortgage servicing rights - Originated servicing rights are recorded when mortgage loans are originated and subsequently sold with the servicing rights retained. Servicing assets are initially recognized at fair value with the income statement effect recorded in gains on sales of loans and amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying financial asset. To determine the fair value of servicing rights, management uses a valuation model that calculates the present value of future cash flows. Assumptions used in the valuation model include market discount rates and anticipated prepayment speeds. In addition, estimates of the cost of servicing per loan, an inflation rate, ancillary income per loan, and default rates are used. The initial fair value relating to the servicing rights is capitalized and amortized into noninterest income in proportion to, and over the period of, estimated future net servicing income. Management assesses impairment of the mortgage servicing rights based on recalculations of the present value of remaining future cash flows using updated market discount rates and prepayment speeds. Subsequent loan prepayments and changes in prepayment assumptions in excess of those forecasted can adversely impact the carrying value of the servicing rights. Impairment is assessed on a stratified basis with any impairment recognized through a valuation allowance for each impaired stratum. The servicing rights are stratified based on the predominant risk characteristics of the underlying loans: fixed-rate loans and adjustable-rate loans. The effect of changes in market interest rates on estimated rates of loan prepayments is the predominant risk characteristic for mortgage servicing rights. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds, and default rates and losses. Mortgage servicing income represents fees earned for servicing loans. Fees for servicing mortgage loans are generally based upon a percentage of the principal balance of the loans serviced, as well as related ancillary income such as late charges. Servicing income is recognized as earned, unless collection is doubtful. The caption in the consolidated statement of income “ Mortgage servicing fees, net ” includes mortgage servicing income, amortization of mortgage servicing rights, the effects of mortgage servicing run-off, and impairment, if applicable. Income taxes - First Federal accounts for income taxes in accordance with the provisions of ASC 740-10, Income Taxes , which requires the use of the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities are recognized for their future tax consequences, attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Premises and equipment - Premises and equipment are stated at cost less accumulated depreciation. Depreciation is recognized and computed on the straight-line method over the estimated useful lives as follows: Buildings 37.5 - 50 years Furniture, fixtures, and equipment 3 - 10 years Software 3 years Automobiles 5 years Transfers of financial assets - Transfers of an entire financial asset, a group of financial assets, or a participating interest in an entire financial asset are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when: (1) the assets have been isolated from First Federal, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) First Federal does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. The mortgage loans that are sold with recourse provisions are accounted for as sales until such time as the loan defaults. Periodically, First Federal sells mortgage loans with “life of the loan” recourse provisions, requiring First Federal to repurchase the loan at any time if it defaults. The remaining balance of such loans at December 31, 2018 , December 31, 2017 and June 30, 2017 , was approximately $5.6 million , $5.6 million and $6.5 million , respectively. Of these loans, no loans were repurchased during the year ended December 31, 2018 or six months ended December 31, 2017 , and one loan was repurchased in the amount of $100,000 during the year ended June 30, 2017 . There is an associated allowance of $19,000 , $25,000 and $33,000 at December 31, 2018 , December 31, 2017 and June 30, 2017 , respectively, included in “accrued expenses and other liabilities” on the consolidated balance sheets related to these loans. Bank-owned life insurance - The carrying amount of life insurance approximates fair value. Fair value of life insurance is estimated using the cash surrender value, less applicable surrender charges. The change in cash surrender value is included in noninterest income. Off-balance-sheet credit-related financial instruments - In the ordinary course of business, First Federal has entered into commitments to extend credit, including commitments under lines of credit, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded when they are funded. Advertising costs - First Federal expenses advertising costs as they are incurred. Comprehensive income (loss) - Accounting principles generally require that recognized revenue, expenses, and gains and losses be included in net income (loss) . Although certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale securities, are reported as a separate component of the equity section of the consolidated balance sheets, such items, along with net income (loss) , are components of comprehensive income (loss) . Dividend restriction - Banking regulations require maintaining certain capital levels and may limit the dividends paid by the Bank to the Company or by the Company to shareholders. Fair value measurements - Fair values of financial instruments are estimated using relevant market information and other assumptions ( Note 14 ). Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect these estimates. Segment information - First Federal is engaged in the business of attracting deposits and providing lending services. Substantially all income is derived from a diverse base of commercial, mortgage, and consumer lending activities and investments. The Company’s activities are considered to be a single industry segment for financial reporting purposes. Employee Stock Ownership Plan - The cost of shares issued to the ESOP but not yet allocated to participants is shown as a reduction of shareholders' equity. Compensation expense is based on the market price of shares as they are committed to be released to participants' accounts. Dividends on allocated ESOP shares reduce retained earnings while dividends on unearned ESOP shares reduce debt and accrued interest. Earnings (loss) per Share - Basic earnings (loss) per share ("EPS") is computed by dividing net income or (loss), reduced by earnings allocated to participating shares of restricted stock, by the weighted-average number of common shares outstanding during the period. As ESOP shares are committed to be released they become outstanding for EPS calculation purposes. ESOP shares not committed to be released are not considered outstanding for basic or diluted EPS calculations. The basic EPS calculation excludes the dilutive effect of all common stock equivalents. Diluted earnings per share reflects the weighted-average potential dilution that could occur if all potentially dilutive securities or other commitments to issue common stock were exercised or converted into common stock using the treasury stock method. According to the provisions of 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. At this time the Company has no share-based payment awards nor paid a dividend. Recently adopted accounting pronouncements - In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606) . In August 2015, FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date , which postponed the effective date of 2014-09. Subsequently, in March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations . This amendment clarifies that an entity should determine if it is the principal or the agent for each specified good or service promised in a contract with a customer. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing . The core principle of Topic 606 is that an entity must recognize revenue when it has satisfied a performance obligation of transferring promised goods or services to a customer. In general, the new guidance requires companies to use more judgment and make more estimates than under current guidance, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. These standards were effective for interim and annual periods beginning after December 15, 2017. The Company has analyzed its revenue sources of noninterest income to determine when the satisfaction of the performance obligation occurs and the appropriate recognition of revenue. The adoption of these ASUs did not have

At December 31, 2018 , there were 69 investment securities with $6.7 million of unrealized losses and a fair value of approximately $268.5 million . At December 31, 2017 , there were 63 investment securities with $3.2 million of unrealized losses and a fair value of approximately $233.2 million . At June 30, 2017 , there were 42 investment securities with $1.8 million of unrealized losses and a fair value of approximately $164.9 million . Management believes that the unrealized losses on investment securities relate principally to the general change in interest rates and illiquidity, and not credit quality, that has occurred since the initial purchase, and such unrecognized losses or gains will continue to vary with general interest rate level fluctuations in the future. Certain investments in a loss position are guaranteed by government entities or government sponsored entities. The Company does not intend to sell the securities in an unrealized loss position and believes it is not likely it will be required to sell these investments prior to a market price recovery or maturity. There were no OTTI losses during the year ended December 31, 2018 , six months ended December 31, 2017 , and years ended June 30, 2017 and 2016 . The amortized cost and estimated fair value of investment securities by contractual maturity are shown in the following tables at the dates indicated. Expected maturities of mortgage-backed securities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties; therefore, these securities are shown separately.

An asset is considered substandard if it is inadequately protected by the current net worth and pay capacity of the borrower or of any collateral pledged. Substandard assets include those characterized by the distinct possibility that First Federal will sustain some loss if the deficiencies are not corrected. Assets classified as doubtful have all the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses present make collection or liquidation in full highly questionable and improbable, on the basis of currently existing facts, conditions, and values. Assets classified as loss are those considered uncollectible and of such little value that their continuance as assets without the establishment of a specific loss reserve is not warranted. When First Federal classifies problem assets as either substandard or doubtful, it may establish a specific allowance to address the risk specifically or First Federal may allow the loss to be addressed in the general allowance. General allowances represent loss allowances that have been established to recognize the inherent risk associated with lending activities but that, unlike specific allowances, have not been specifically allocated to particular problem assets. When an insured institution classifies problem assets as a loss, it is required to charge off such assets in the period in which they are deemed uncollectible. Assets that do not currently expose First Federal to sufficient risk to warrant classification as substandard or doubtful but possess identified weaknesses are designated as either watch or special mention assets; risk ratings 4 and 5 in our risk rating system, respectively. Loans not otherwise classified are considered pass graded loans and are rated 1-3 in our risk rating system. Additionally, First Federal categorizes loans as performing or nonperforming based on payment activity. Loans that are more than 90 days past due and nonaccrual loans are considered nonperforming.

If, in the future, this portion of retained earnings is used for any purpose other than to absorb losses on loans or on property acquired through foreclosure, federal income taxes may be imposed at the then-prevailing corporate tax rates. The Company does not contemplate that such amounts will be used for any purpose that would create a federal income tax liability; therefore, no provision has been made. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. These calculations are based on many complex factors including estimates of the timing of reversals of temporary differences, the interpretation of federal income tax laws, and a determination of the differences between the tax and the financial reporting basis of assets and liabilities. Actual results could differ significantly from the estimates and interpretations used in determining the current and deferred income tax assets and liabilities. During the year ended June 30, 2015, the Company contributed $400,000 in cash and $9.3 million in common stock to the Foundation. Under current Federal income tax regulations, charitable contribution deductions are limited to 10% of taxable income. Accordingly, the $9.7 million contribution created a carryforward for income tax purposes with a deferred tax asset of $3.3 million and related valuation allowance of $1.9 million for financial statement reporting purposes. At December 31, 2018 , the balance of the contribution carryforward totaled $7.2 million . The contribution carryforward will expire in 2019. A valuation allowance is provided when it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company evaluates whether its deferred tax assets will be realized and adjusts the amount of its valuation allowance, if necessary. There was a valuation allowance of $1.2 million and $1.2 million , at December 31, 2018 and 2017 , respectively, the reduction of which predominantly relates to the change in corporate tax rate. The Company applies the provisions of FASB ASC 740 that require the application of a more-likely-than-not recognition criterion for the reporting of uncertain tax positions on its financial statements. The Company had no unrecognized tax assets at December 31, 2018 and 2017 . During the year ended December 31, 2018 and six months ended December 31, 2017 , the Company recognized no interest and penalties. The Company recognizes interest and penalties in income tax expense. The Company files income tax returns in the U.S. federal jurisdiction and is no longer subject to U.S. federal income tax examinations by tax authorities for years ending before June 30, 2015 . On December 22, 2017, the U.S. Government enacted the Tax Act. The Tax Act amends the Internal Revenue Code to reduce tax rates and modify policies, credits, and deductions for individuals and businesses. For businesses, the Tax Act reduces the corporate federal tax rate from a maximum of 35% to a flat 21% rate. The corporate tax rate reduction was effective January 1, 2018. The Tax Act required a revaluation the Company’s deferred tax assets and liabilities to account for the future impact of lower corporate tax rates and other provisions of the legislation. As a result of the Company’s revaluation, the net deferred tax asset was reduced through an increase to the provision for income taxes. The Company has also elected to change its tax year end from June 30 to December 31 beginning with the six months ended December 31, 2017. As a result of changing the tax year, the Company recorded an increase to the deferred tax asset valuation allowance to account for the loss of six months of taxable income. The components of net deferred tax assets and liabilities at the periods shown are summarized as follows: December 31, 2018 December 31, 2017 June 30, 2017 (In thousands) Deferred tax assets Allowance for loan losses $ 2,049 $ 1,888 $ 2,957 Unrealized loss on securities available for sale 1,264 425 238 Accrued compensation 397 284 952 Nonaccrual loans 4 4 6 ESOP timing differences 195 138 111 Restricted stock awards 134 124 332 Deferred investment loss — 16 — Contribution carryforward 1,515 1,639 2,716 Total deferred tax assets 5,558 4,518 7,312 Deferred tax liabilities Deferred loan fees 436 440 474 FHLB stock dividends 488 495 801 Accumulated depreciation 734 763 1,249 Deferred investment gain 14 — 11 Other, net 23 85 24 Total deferred tax liabilities 1,695 1,783 2,559 Deferred tax asset, net 3,863 2,735 4,753 Deferred tax asset valuation allowance (1,224 ) (1,225 ) (1,898 ) Deferred tax asset, net of valuation allowance $ 2,639 $ 1,510 $ 2,855

Compensation Related Costs [Abstract]
Benefit Plans	Benefit Plans Multi-employer Pension Plan The Bank participates in the Pentegra Defined Benefit Plan for Financial Institutions (the Pentegra DB Plan), a tax-qualified defined-benefit pension plan that covered substantially all employees after one year of continuous employment. Pension benefits vested over a period of five years of credited service. The Pentegra DB Plan’s Employer Identification Number is 13-5645888 and the Plan Number is 12004. The Pentegra DB Plan operates as a multi-employer plan for accounting purposes and as a multiple-employer plan under the Employee Retirement Income Security Act of 1974 and the Internal Revenue Code. There are no collective bargaining agreements in place that require contributions to the Pentegra DB Plan. The Pentegra Defined Benefit Plan was frozen and no new benefits were allowed as of February 1, 2010. The Pentegra DB Plan is a single plan under Internal Revenue Code Section 413(c) and, as a result, all of the assets stand behind all of the liabilities. Accordingly, under the Pentegra DB Plan, contributions made by a participating employer may be used to provide benefits to participants of other participating employers. The table below presents the funded status (market value of plan assets divided by funding target) of the plan as of July 1: 2018 2017 2016 Source Valuation Report Valuation Report Valuation Report Our plan 112.5% 113.1% 106.3% There was no change to the funded status of the plan as of December 31, 2018 . First Federal’s contributions to the Pentegra DB Plan are not more than 5% of the total contributions to the Pentegra DB Plan. First Federal’s policy is to fund pension costs as accrued. Total contributions during the periods shown were: Year Ended Six Months Ended Years Ended December 31, 2018 December 31, 2017 December 31, 2017 June 30, 2017 Date Paid Amount Date Paid Amount Date Paid Amount Date Paid Date Paid (In thousands) 12/31/2018 $ 386 12/13/2017 $ 400 10/12/2016 $ 75 10/14/2015 $ 74 12/19/2016 524 1/4/2016 425 $ 386 $ 400 $ 599 $ 499 Nonqualified Deferred Compensation Plan First Federal also sponsors a nonqualified Deferred Compensation Plan for members of the board of directors and eligible officer-level employees. This plan, approved by the Board on February 1, 2012, allows eligible participants to defer and invest a portion of their earnings in a selection of investment options identified in the plan at no expense to First Federal. All deferrals are remitted to Pentegra, the Plan Administrator, and held in a trust. The aggregate balance held in trust at December 31, 2018 , was $784,000 . The Company also has agreements with certain key officers that provide for potential payments upon retirement, disability, termination, change in control and death. 401(k) Plan First Federal maintains a single-employer 401(k) plan. Employees may contribute up to 100% of their pre-tax compensation to the 401(k) plan, subject to regulatory limits. First Federal provides matching funds of 50% limited to the first 6% of salary contributed. First Federal's contributions were $245,000 , $110,000 , $177,000 , and $159,000 during the year ended December 31, 2018 , six months ended December 31, 2017 , and years ended June 30, 2017 , and 2016 , respectively. Employee Stock Ownership Plan In connection with the mutual to stock conversion, the Company established an ESOP for eligible employees of the Company and the Bank. Employees of the Company who have been credited with at least 1,000 hours of service during a 12 -month period are eligible to participate in the ESOP. Pursuant to the Plan, the ESOP purchased in the open market 8% of the common stock originally issued in the mutual to stock conversion. As of December 31, 2018 , 1,048,029 shares, or 100% of the total, have been purchased in the open market at an average price of $ 12.45 per share with funds borrowed from First Northwest. The Bank will make contributions to the ESOP in amounts necessary to amortize the ESOP loan payable to First Northwest over a period of 20 years, bearing estimated interest at 2.46% . Shares purchased by the ESOP with the loan proceeds are held in a suspense account and allocated to ESOP participants on a pro rata basis as principal and interest payments are made by the ESOP to the Company. The loan is secured by shares purchased with the loan proceeds and will be repaid by the ESOP with funds from the Bank's discretionary contributions to the ESOP and earnings on the ESOP assets. Annual principal and interest payments of $835,000 , $835,000 , and $810,000 , were made by the ESOP during the years ended December 31, 2018 , and June 30, 2017 , and 2016 , respectively. No payment was made during the six months ended December 31, 2017 . As shares are committed to be released from collateral, the Company reports compensation expense equal to the average daily market prices of the shares and the shares become outstanding for EPS computations. The compensation expense is accrued monthly throughout the year. Dividends on allocated ESOP shares will be recorded as a reduction of retained earnings; dividends on unallocated ESOP shares will be recorded as a reduction of debt and accrued interest. Compensation expense related to the ESOP for the year ended December 31, 2018 , six months ended December 31, 2017 ,and years ended June 30, 2017 and 2016 , was $851,000 , $436,000 , and $763,000 and $677,000 , respectively. Shares issued to the ESOP as of the dates indicated are as follows: December 31, 2018 December 31, 2017 June 30, 2017 (Dollars in thousands) Allocated shares 201,026 148,137 121,695 Unallocated shares 847,003 899,892 926,334 Total ESOP shares issued 1,048,029 1,048,029 1,048,029 Fair value of unallocated shares $ 12,561 $ 14,668 $ 14,608 Stock-based Compensation On November 16, 2015 , the Company's shareholders approved the First Northwest Bancorp 2015 Equity Incentive Plan (the "EIP"), which provides for the grant of incentive stock options, non-qualified stock options, restricted stock and restricted stock units to eligible participants. The cost of awards under the EIP generally is based on the fair value of the awards on their grant date. The maximum number of shares that may be utilized for awards under the EIP is 1,834,050 . Under the EIP stock options may be granted that, upon exercise, result in the issuance of up to 1,310,036 shares of common stock and up to 524,014 shares of restricted stock may be awarded. Shares of common stock issued under the EIP may be authorized but unissued shares or repurchased shares. During the year ended June 30, 2017, the Company purchased and retired 523,014 shares of common stock to be used for future stock awards. During the year ended December 31, 2018 , 65,000 shares of restricted stock were awarded and no stock options were granted. There were 50,000 shares of restricted stock awarded during the six months ended December 31, 2017 , and no stock options were granted. There were 402,500 shares awards during the year ended June 30, 2017 , and no stock options were granted. Awarded shares of restricted stock vest over five years from the date of grant as long as the eligible participant remains in service to the Company. The Company recognizes compensation expense for the restricted stock awards based on the fair value of the shares at the award date. For the year ended December 31, 2018 , six months ended December 31, 2017 , and years ended June 30, 2017 and 2016 , total compensation expense for the EIP was $1.1 million , $589,000 , $977,000 , and $0 , respectively. Included in the above compensation expense for the year ended December 31, 2018 , six months ended December 31, 2017 , and years ended June 30, 2017 and 2016 , was directors' compensation of $343,000 , $174,000 , $383,000 , and $0 , respectively. The following tables provide a summary of changes in non-vested restricted stock awards for the periods shown: For the Year Ended December 31, 2018 Weighted-Average Grant Date Shares Fair Value Non-vested at January 1, 2018 347,600 $ 13.18 Granted 65,000 15.38 Vested (65,324 ) 13.06 Canceled (1) (18,076 ) 13.06 Forfeited (38,600 ) 13.14 Non-vested at December 31, 2018 290,600 13.72 (1) A surrender of vested stock awards by a participant surrendering the number of shares valued at the current stock price at the vesting date to cover the total cost of the vested shares. The surrendered shares are canceled and are unavailable for reissue. As of December 31, 2018 , there was $3.5 million of total unrecognized compensation cost related to non-vested shares granted as restricted stock awards. The cost is expected to be recognized over the remaining weighted-average vesting period of approximately 3.3 years .

Regulatory Capital Requirements

Regulatory Capital Requirements	12 Months Ended
	Dec. 31, 2018
Banking and Thrift [Abstract]
Regulatory Capital Requirements	Regulatory Capital Requirements Under Federal regulations, pre-conversion retained earnings are restricted for the protection of pre-conversion depositors. The Company is a bank holding company under the supervision of the Federal Reserve Bank of San Francisco. Bank holding companies are subject to capital adequacy requirements of the Federal Reserve Board under the Bank Holding Company Act of 1956, as amended, and the regulations of the Federal Reserve Board. The Bank is a federally insured institution and thereby is subject to the capital requirements established by the FDIC. The Federal Reserve Board capital requirements generally parallel the FDIC requirements. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company's financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Prompt corrective action provisions are not applicable to bank holding companies. Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the table that follows) of total and Tier I capital to risk-weighted assets (as defined in the regulations) and of Tier 1 capital to average assets. Effective January 1, 2015 (with some changes transitioned into full effectiveness over two to four years), First Northwest Bancorp and First Federal became subject to capital requirements which created a required ratio for common equity Tier 1 (“CET1”) capital, increased the leverage and Tier 1 capital ratios, changed the risk-weightings of certain assets for purposes of the risk-based capital ratios, created an additional capital conservation buffer over the required capital ratios and changed what qualifies as capital for purposes of meeting these various capital requirements. First Northwest Bancorp and First Federal are required to maintain additional levels of Tier 1 common equity over the minimum risk-based capital levels to avoid limitations on dividends, repurchase shares and paying discretionary bonuses. The minimum requirements are a ratio of common equity Tier 1 capital ("CET1 capital") to total risk-weighted assets the (“CET1 risk-based ratio”) of 4.5% , a Tier 1 capital ratio of 6.0% , a total capital ratio of 8.0% , and a leverage ratio of 4.0% . In addition to the capital requirements, there were a number of changes in what constitutes regulatory capital, subject to a certain transition period. These changes include the phasing-out of certain instruments as qualifying capital. The Bank does not have any of these instruments. Mortgage servicing and deferred tax assets over designated percentages of CET1 are deducted from capital, subject to a transition period ending December 31, 2017. CET1 consists of Tier 1 capital less all capital components that are not considered common equity. In addition, Tier 1 capital includes accumulated other comprehensive income, which includes all unrealized gains and losses on available for sale debt and equity securities, subject to a transition period ending December 31, 2017. Because of the Bank’s asset size, the Bank is not considered an advanced approaches banking organization and has elected to permanently opt-out of the inclusion of unrealized gains and losses on available for sale debt and equity securities in its capital calculations. The requirements also include changes in the risk-weighting of assets to better reflect credit risk and other risk exposure. These include a 150% risk weight (up from 100% ) for certain high volatility commercial real estate acquisition, development and construction loans and for non-residential mortgage loans that are 90 days past due or otherwise in nonaccrual status; a 20% (up from 0% ) credit conversion factor for the unused portion of a commitment with an original maturity of one year or less that is not unconditionally cancellable; and a 250% risk weight (up from 100% ) for mortgage servicing and deferred tax assets that are not deducted from capital. In order to avoid limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses based on percentages of eligible retained income that could be utilized for such actions, First Northwest Bancorp and First Federal must maintain CET1 capital at an amount greater than the required minimum levels plus a capital conservation buffer. This new capital conservation buffer requirement was phased in starting in January 2016 requiring a buffer of 0.625% of risk-weighted assets and will increase each year until fully implemented to an amount of 2.5% of risk-weighted assets in January 2019. As of December 31, 2018 , the conservation buffer was 1.875% . Under the new standards, in order to be considered well-capitalized, the Bank must maintain a CET1 risk-based ratio of 6.5% (new), a Tier 1 risk-based ratio of 8% (increased from 6% ), a total risk-based capital ratio of 10% (unchanged) and a leverage ratio of 5% (unchanged). As of December 31, 2018 , the most recent regulatory notifications categorized First Federal as “well capitalized” under the regulatory framework for prompt corrective action. To be categorized as “well capitalized,” the Bank must maintain minimum total risk-based, CET1 risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the following table. There are no conditions or events since that notification that management believes have changed First Federal’s category. At periodic intervals, banking regulators routinely examine First Northwest and First Federal as part of their legally prescribed oversight of the banking industry. A future examination could include a review of certain transactions or other amounts reported in the Company's consolidated financial statements. Based on these examinations, the regulators can direct that the Company's consolidated financial statements be adjusted in accordance with their findings. In view of the uncertain regulatory environment in which First Northwest and First Federal operate, the extent, if any, to which a forthcoming regulatory examination may ultimately result in adjustments to the accompanying consolidated financial statements cannot presently be determined. At December 31, 2018 , First Federal exceeded all regulatory capital requirements. Effective with the September 30, 2018 as-of-date, First Northwest Bancorp was transitioned back to the small bank holding company filing requirements which do not require capital ratios to be reported.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies First Federal is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments generally represent a commitment to extend credit in the form of loans. The instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets. First Federal’s exposure to credit loss, in the event of nonperformance by the other party to the financial instrument for commitments to extend credit, is represented by the contractual notional amount of those instruments. First Federal uses the same credit policies in making commitments as it does for on-balance-sheet instruments. Management does not anticipate any material loss as a result of these transactions. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established by the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of these commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. First Federal evaluates each customer’s creditworthiness on a case-by-case basis. First Federal did not incur any significant losses on its commitments for the year ended December 31, 2018 , six months ended December 31, 2017 , and year ended June 30, 2017 . The following financial instruments were outstanding whose contract amounts represent credit risk at: December 31, 2018 December 31, 2017 June 30, 2017 (In thousands) Commitments to grant loans $ 625 $ 543 $ 670 Standby letters of credit 223 183 183 Unfunded commitments under lines of credit or existing loans 98,847 99,416 67,800 Legal contingencies - Various legal claims may arise from time to time in the normal course of business, which, in the opinion of management, have no current material effect on First Federal’s consolidated financial statements. Significant group concentrations of credit risk - Concentration of credit risk is the risk associated with a lack of diversification, such as having substantial loan concentrations in a specific type of loan within First Federal’s loan portfolio, thereby exposing First Federal to greater risks resulting from adverse economic, political, regulatory, geographic, industrial, or credit developments. Loans to one borrower are subject to the state banking regulations general limitation of 20 percent of First Federal’s equity, excluding accumulated other comprehensive income. At December 31, 2018 , December 31, 2017 and June 30, 2017 First Federal’s most significant concentration of credit risk was in loans secured by real estate. These loans totaled approximately $767.6 million , $742.9 million and $697.5 million , or 88.3% , 94.5% , and 95.0% , of First Federal’s total loan portfolio at December 31, 2018 , December 31, 2017 and June 30, 2017 , respectively. Real estate construction, including land acquisition and land development, commercial real estate, multi-family, home equity, and one- to four-family residential loans are included in the total loans secured by real estate for purposes of this calculation. After a period of decline the real estate market has begun to recover, which has helped stabilize nonperforming loans and the allowance for loan losses. At December 31, 2018 , December 31, 2017 and June 30, 2017 , First Federal’s most significant investment concentration of credit risk was with the U.S. Government, its agencies, and Government-Sponsored Enterprises (GSEs). First Federal’s exposure, which results from positions in securities issued by the U.S. Government, its agencies, and securities guaranteed by GSEs, was $243.4 million , $256.8 million , and $238.7 million or 77.7% , 73.9% , and 83.8% , of First Federal’s total investment portfolio (including FHLB stock) at December 31, 2018 , December 31, 2017 , and June 30, 2017 , respectively.

Fair Value Disclosures [Abstract]
Fair Value Accounting and Measurement	Fair Value Accounting and Measurement Fair value is the price to sell an asset or transfer a liability in an orderly transaction between market participants in the Company’s principal market. The Company has established and documented its process for determining the fair values of its assets and liabilities, where applicable. Fair value is based on quoted market prices, when available, for identical or similar assets or liabilities. In the absence of quoted market prices, management determines the fair value of the Company’s assets and liabilities using valuation models or third-party pricing services, both of which rely on market-based parameters when available, such as interest rate yield curves, option volatilities and credit spreads, or unobservable inputs. Unobservable inputs may be based on management’s judgment, assumptions, and estimates related to credit quality, liquidity, interest rates, and other relevant inputs. Any changes to valuation methodologies are reviewed by management to ensure they are relevant and justified. Valuation methodologies are refined as more market-based data becomes available. A three-level valuation hierarchy is used in determining fair value that is based on the transparency of the inputs used in the valuation process. The inputs used in determining fair value in each of the three levels of the hierarchy are as follows: Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 - Either: (i) quoted prices for similar assets or liabilities; (ii) observable inputs, such as interest rates or yield curves; or (iii) inputs derived principally from or corroborated by observable market data. Level 3 - Unobservable inputs. The hierarchy gives the highest ranking to Level 1 inputs and the lowest ranking to Level 3 inputs. The level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the overall fair value measurement. Qualitative disclosures of valuation techniques - Securities available for sale: where quoted prices are available in an active market, securities are classified as Level 1. Level 1 instruments include highly liquid government bonds, securities issued by the U.S. Treasury, and exchange-traded equity securities. If quoted prices are not available, management determines fair value using pricing models, quoted prices of similar securities, which are considered Level 2, or discounted cash flows. In certain cases, where there is limited activity in the market for a particular instrument, assumptions must be made to determine their fair value. Such instruments are classified as Level 3. Assets and liabilities measured at fair value on a recurring basis - Assets and liabilities are considered to be fair valued on a recurring basis if fair value is measured regularly (i.e., daily, weekly, monthly, or quarterly). The following tables show the Company’s assets and liabilities measured at fair value on a recurring basis at the dates indicated: December 31, 2018 Quoted Prices in or Liabilities Significant Inputs Significant Inputs (Level 1) (Level 2) (Level 3) Total (In thousands) Securities available for sale Municipal bonds $ — $ 869 $ — $ 869 ABS agency — 25,752 — 25,752 ABS corporate — 36,723 — 36,723 SBA — 9,888 — 9,888 Corporate debt — 35,670 — 35,670 MBS agency — 143,455 — 143,455 MBS corporate — 10,610 — 10,610 $ — $ 262,967 $ — $ 262,967 December 31, 2017 Quoted Prices in Significant Significant (Level 1) (Level 2) (Level 3) Total (In thousands) Securities available for sale Municipal bonds $ — $ 13,434 $ — $ 13,434 ABS agency — 21,770 — 21,770 ABS corporate — 22,768 — 22,768 SBA — 19,908 — 19,908 Corporate debt — 47,274 — 47,274 MBS agency — 144,542 — 144,542 MBS corporate — 20,546 — 20,546 $ — $ 290,242 $ — $ 290,242 June 30, 2017 Quoted Prices in Significant Significant (Level 1) (Level 2) (Level 3) Total (In thousands) Securities available for sale Municipal bonds $ — $ 22,223 $ — $ 22,223 Agency bonds — 4,926 — 4,926 ABS agency — 7,648 — 7,648 ABS corporate — 9,813 — 9,813 SBA — 14,178 — 14,178 MBS agency — 143,436 — 143,436 MBS corporate — 26,369 — 26,369 $ — $ 228,593 $ — $ 228,593 Assets measured at fair value on a nonrecurring basis - Assets are considered to be fair valued on a nonrecurring basis if the fair value measurement of the instrument does not necessarily result in a change in the amount recorded on the consolidated balance sheets. Generally, nonrecurring valuation is the result of the application of other accounting pronouncements that require assets or liabilities to be assessed for impairment or recorded at the lower of cost or fair value.

Earnings Per Share [Abstract]
Earnings per Share	Earnings per Share Basic earnings per share are computed by dividing income available to common shareholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. The following table presents a reconciliation of the components used to compute basic and diluted earnings per share for the periods shown. For the Year Ended For the Six Months Ended For the Years Ended June 30, December 31, 2018 December 31, 2017 2017 2016 (In thousands, except share data) Numerator: Net income $ 7,105 $ 1,659 $ 5,118 $ 3,992 Denominator: Basic weighted average common shares outstanding 10,331,902 10,606,798 11,084,726 12,049,621 Dilutive restricted stock grants 102,535 96,283 85,314 — Diluted weighted average common shares outstanding 10,434,437 10,703,081 11,170,040 12,049,621 Basic earnings $ 0.69 $ 0.16 $ 0.46 $ 0.33 Diluted earnings $ 0.68 $ 0.16 $ 0.46 $ 0.33 Potential dilutive shares are excluded from the computation of EPS if their effect is anti-dilutive. For the year ended December 31, 2018 , anti-dilutive shares outstanding related to restricted stock awards totaled 48,040 because the incremental shares under the treasury stock method of calculation resulted in them being anti-dilutive. For the six months ended December 31, 2017 , and the years ended June 30, 2017 and 2016 , there were no anti-dilutive shares outstanding related to restricted stock awards. As of December 15, 2015, the ESOP had purchased 1,048,029 shares of First Northwest Bancorp in the open market. Unallocated ESOP shares are not included as outstanding shares for basic or diluted earnings per share calculations.

Noninterest Income	Noninterest Income On January 1, 2018, the Company adopted the amendments of ASU 2014-09 Revenue from Contracts with Customers (Topic 606) and all subsequent ASUs that modified Topic 606. The Company has included the following table regarding the Company’s noninterest income for the periods presented. Year Ended December 31, 2018 Noninterest income: Loan fees (1) $ 807 Deposit fees 1,671 Debit interchange income 137 Credit card interchange income 1,740 Gain on loan sales, net (1) 577 Investment securities gain (loss), net (1) 77 Increase in cash surrender value of BOLI (1) 595 Other income: Investment services revenue 226 Gain or loss on subsidiary (1) 68 Remaining other income 21 Total other income 315 Total noninterest income $ 5,919 (1) Not within scope of Topic 606 The Company recognizes revenue as it is earned and noted no impact to its revenue recognition policies as a result of the adoption of ASU 2014-09. The following is a discussion of key revenues within the scope of the new revenue guidance. Deposit fees - The Company earns fees from its deposit customers for account maintenance, transaction-based activity 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 the fees are recognized on a monthly basis as the service period is completed. Transaction-based fees on deposit accounts are charged to deposit customers for specific services provided to the customer, such as non-sufficient funds fees, overdraft fees, and wire fees. 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 interchange income - Debit and Automated Teller Machine ("ATM") interchange income represent fees earned when a debit card issued by the Company is used. The Company earns interchange fees from debit cardholder transactions through card networks. In addition, the Company earns interchange fees for use of its ATM by customers of other banking institutions. Interchange fees are based on purchase volumes and other factors and are recognized as transactions occur. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the cardholder's debit card. Certain expenses directly associated with the credit and debit card are netted against interchange income. Credit card interchange income - Credit card interchange income represents fees earned when a credit card issued by the Bank through a third-party vendor is used. Similar to the debit card interchange, the Bank earns an interchange fee for each transaction made with a Bank-branded credit card. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the cardholder's credit card. Certain expenses directly related to the credit card interchange contract are netted against interchange income. Investment services revenue - Commissions received on the sale of investment related products is determined by a percentage of underlying instruments sold and is recognized when the sale is finalized. Gains/losses on the sale of other real estate owned are included in non-interest expense and are generally recognized when the performance obligation is complete. This is typically at delivery of control over the property to the buyer at time of each real estate closing.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies - (Policies)	12 Months Ended
	Dec. 31, 2018
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Use of estimates	Use of estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make assumptions. These assumptions result in estimates that affect the reported amounts of assets and liabilities, revenues and expenses, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to a determination of the allowance for loan losses, fair value of financial instruments, deferred tax assets and liabilities, and the valuation of impaired loans.
Principles of consolidation	Principles of consolidation - The accompanying consolidated financial statements include the accounts of First Northwest Bancorp and its wholly owned subsidiary, First Federal. All material intercompany accounts and transactions have been eliminated in consolidation.
Subsequent events	Subsequent events - The Company has evaluated subsequent events for potential recognition and disclosure and determined there are no such events or transactions requiring recognition or disclosure.
Cash and cash equivalents	Cash and cash equivalents - Cash and cash equivalents consist of currency on hand, due from banks, and interest-bearing deposits with financial institutions with an original maturity of three months or less. The amounts on deposit fluctuate and, at times, exceed the insured limit by the FDIC, which potentially subjects First Federal to credit risk. First Federal has not experienced any losses due to balances exceeding FDIC insurance limits.
Restricted assets	Restricted assets - Federal Reserve Board regulations require maintenance of certain minimum reserve balances on deposit with the Federal Reserve Bank of San Francisco.
Investment securities	Investment securities - Investment securities are classified into one of three categories: (1) held-to-maturity, (2) available-for-sale, or (3) trading. First Federal had no trading securities at December 31, 2018 , December 31, 2017 and June 30, 2017 . Investment securities are categorized as held-to-maturity when First Federal has the positive intent and ability to hold those securities to maturity. Securities that are held-to-maturity are stated at cost and adjusted for amortization of premiums and accretion of discounts, which are recognized as adjustments to interest income. Investment securities categorized as available for sale are generally held for investment purposes (to maturity), although unanticipated future events may result in the sale of some securities. Available-for-sale securities are recorded at fair value, with the unrealized holding gain or loss reported in other comprehensive income (OCI), net of tax, as a separate component of shareholders' equity. Realized gains or losses are determined using the amortized cost basis of securities sold using the specific identification method and are included in earnings. Dividend and interest income on investments are recognized when earned. Premiums and discounts are recognized in interest income using the level yield method over the period to maturity. The Company reviews investment securities for other-than-temporary impairment (OTTI) on a quarterly basis. For debt securities, the Company considers whether management intends to sell a security or if it is likely that the Company will be required to sell the security before recovery of the amortized cost basis of the investment, which may be maturity. For debt securities, if management intends to sell the security or it is likely that the Company will be required to sell the security before recovering its cost basis, the entire impairment loss would be recognized as OTTI and charged against earnings. If management does not intend to sell the security and it is not likely that the Company will be required to sell the security, but management does not expect to recover the entire amortized cost basis of the security, only the portion of the impairment loss representing credit losses would be recognized in earnings. The credit loss on a 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 security being measured for potential OTTI. The remaining impairment related to all other factors, i.e. the difference between the present value of the cash flows expected to be collected and fair value, is recognized as a charge to OCI. Impairment losses related to all other factors are presented as separate categories within OCI. If there is an indication of additional credit losses, the security is re-evaluated according to the procedures described above.
Federal Home Loan Bank stock	Federal Home Loan Bank stock - First Federal’s investment in Federal Home Loan Bank of Des Moines (FHLB) stock is carried at cost, which approximates fair value. As a member of the FHLB system, First Federal is required to maintain a minimum investment in FHLB stock based on specific percentages of its outstanding mortgages, total assets, or FHLB advances. At December 31, 2018 and 2017 , First Federal’s minimum investment requirement was approximately $6.9 million and $7.0 million , respectively. First Federal was in compliance with the FHLB minimum investment requirement at December 31, 2018 and 2017 . First Federal may request redemption at par value of any stock in excess of the amount First Federal is required to hold. Stock redemptions are granted at the discretion of the FHLB. Management evaluates FHLB stock for impairment based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) the significance of any decline in net assets of the FHLB compared with the capital stock amount for the FHLB and the length of time this situation has persisted, (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB, (3) the impact of legislative and regulatory changes on institutions and, accordingly, the customer base of the FHLB, and (4) the liquidity position of the FHLB. Based on its evaluation, First Federal did not recognize an OTTI loss on its FHLB stock at December 31, 2018 and 2017 .
Loans held for sale	Loans held for sale - Mortgage loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or fair value. Fair value is determined based upon market prices from third-party purchasers and brokers. Net unrealized losses, if any, are recognized through a valuation allowance by charges to earnings. Gains or losses on the sale of loans are recognized at the time of sale and determined by the difference between net sale proceeds and the net book value of the loan less the estimated fair value of any retained mortgage servicing rights.
Loans receivable	Loans receivable - Loans are stated at the amount of unpaid principal, net of charge-offs, unearned income, allowance for loan loss (ALLL) and any deferred fees or costs. Interest on loans is calculated using the simple interest method based on the month end balance of the principal amount outstanding and is credited to income as earned. The estimated life is adjusted for prepayments. Each loan segment and class inherently contains differing credit risk profiles depending on the unique aspects of that segment or class of loans. For example, borrowers tend to consider their primary residence and access to transportation for employment-related purposes as basic requirements; accordingly, many consumers prioritize making payments on real estate first-mortgage loans and vehicle loans. Conversely, second-mortgage real estate loans or unsecured loans may not be supported by sufficient collateral; thus, in the event of financial hardship, borrowers may tend to place less importance on maintaining these loans as current and the Bank may not have adequate collateral to provide a secondary source of repayment in the event of default. Notwithstanding the various risk profiles unique to each class of loan, management believes that the credit risk for all loans is similarly dependent on essentially the same factors, including the financial strength of the borrower, the cash flow available to service maturing debt obligations, the condition and value of underlying collateral, the financial strength of any guarantors, and other factors. Loans are classified as impaired when, based on current information and events, it is probable that First Federal will be unable to collect the scheduled payments of principal and interest when due, in accordance with the terms of the original loan agreement. The carrying value of impaired loans is based on the present value of expected future cash flows discounted at each loan’s effective interest rate or, for collateral dependent loans, at fair value of the collateral, less selling costs. If the measurement of each impaired loan’s value is less than the recorded investment in the loan, First Federal recognizes this impairment and adjusts the carrying value of the loan to fair value through the allowance for loan losses. This can be accomplished by charging off the impaired portion of the loan or establishing a specific component to be provided for in the allowance for loan losses. The accrual of interest on loans is discontinued at the time the loan is 90 days delinquent, unless the credit is well secured and in process of collection. In all cases, loans are placed on nonaccrual or charged off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not collected for loans that are placed on nonaccrual or charged off is reversed against interest income. The interest on these loans is accounted for on the cash basis or cost recovery method until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. For those loans placed on non-accrual status due to payment delinquency, return to accrual status will generally not occur until the borrower demonstrates repayment ability over a period of not less than six months.
Loan fees	Loan fees - Loan origination fees and certain direct origination costs are deferred and amortized as an adjustment to the yield of the loan over the contractual life using the effective interest method. In the event a loan is sold, the remaining deferred loan origination fees and/or costs are recognized as a component of gains or losses on the sale of loans.
Allowance for loan losses	Allowance for loan losses - First Federal maintains a general allowance for loan losses based on evaluating known and inherent risks in the loan portfolio, including management’s continuing analysis of the factors underlying the quality of the loan portfolio. These factors include changes in the size and composition of the loan portfolio, actual loan loss experience, and current and anticipated economic conditions. The reserve is an estimate based upon factors and trends identified by management at the time the financial statements are prepared. The ultimate recovery of loans is susceptible to future market factors beyond First Federal’s control, which may result in losses or recoveries differing significantly from those provided in the consolidated financial statements. In addition, various regulatory agencies, as an integral part of their examination processes, periodically review First Federal’s allowance for loan losses. Such agencies may require First Federal to recognize additional provisions for loan losses based on their judgment using information available to them at the time of their examination. Allowances for losses on specific problem loans are charged to income when it is determined that the value of these loans and properties, in the judgment of management, is impaired. First Federal accounts for impaired loans in accordance with Accounting Standards Codification (ASC) 310-10-35, Receivables—Overall—Subsequent Measurement . A loan is considered impaired when, based on current information and events, it is probable that First Federal will be unable to collect all amounts due according to the contractual terms of the loan agreement. When a loan has been identified as being impaired, the amount of the impairment is measured by using discounted cash flows, except when it is determined that the sole source of repayment for the loan is the operation or liquidation of the underlying collateral. In such cases, impairment is measured at current fair value generally based on a current appraisal of the collateral, reduced by estimated selling costs. When the measurement of the impaired loan is less than the recorded investment in the loan (including collected interest that has been applied to principal, net deferred loan fees or costs, and unamortized premiums or discounts), loan impairment is recognized by establishing or adjusting an allocation of the allowance for loan losses. Uncollected accrued interest is reversed against interest income. If ultimate collection of principal is in doubt, all cash receipts on impaired loans are applied to reduce the principal balance. The impairment amount for small balance homogeneous loans is calculated using the adjusted historical loss rate for the class and risk category related to each loan, unless the loan is subject to a troubled debt restructuring ("TDR"). A TDR is a loan for which First Federal, for reasons related to the borrower’s financial difficulties, grants a concession to the borrower that First Federal would not otherwise consider. The loan terms that have been modified or restructured due to the borrower’s financial difficulty include, but are not limited to, a reduction in the stated interest rate; an extension of the maturity; an interest rate below market; a reduction in the face amount of the debt; a reduction in the accrued interest; or extension, deferral, renewal, or rewrite of the original loan terms. The restructured loans may be classified “special mention” or “substandard” depending on the severity of the modification. Loans that were paid current at the time of modification may be upgraded in their classification after a sustained period of repayment performance, usually six months or longer, and there is reasonable assurance that repayment will continue. Loans that are past due at the time of modification are classified “substandard” and placed on nonaccrual status. TDR loans may be upgraded in their classification and placed on accrual status once there is a sustained period of repayment performance, usually six months or longer, and there is a reasonable assurance that repayment will continue. First Federal allows reclassification of a troubled debt restructuring back into the general loan pool (as a non-troubled debt restructuring) if the borrower is able to refinance the loan at then-current market rates and meet all of the underwriting criteria of First Federal required of other borrowers. The refinance must be based on the borrower’s ability to repay the debt and no special concessions of rate and/or term are granted to the borrower.
Reserve for unfunded commitments	Reserve for unfunded commitments - Management maintains a reserve for unfunded commitments to absorb probable losses associated with off-balance sheet commitments to lend funds such as unused lines of credit and the undisbursed portion of construction loans. Management determines the adequacy of the reserve based on reviews of individual exposures, current economic conditions, and other relevant factors. The reserve is based on estimates and ultimate losses may vary from the current estimates. The reserve is evaluated on a regular basis and necessary adjustments are reported in earnings during the period in which they become known. The reserve for unfunded commitments is included in "Accrued expenses and other liabilities" on the consolidated balance sheets.
Real estate owned and repossessed assets	Real estate owned and repossessed assets - Real estate owned and repossessed assets include real estate and personal property acquired through foreclosure or repossession, and may include in-substance foreclosed properties. In-substance foreclosed properties are those properties for which the Bank has taken physical possession, regardless of whether formal foreclosure proceedings have taken place.
Mortgage servicing rights	Mortgage servicing rights - Originated servicing rights are recorded when mortgage loans are originated and subsequently sold with the servicing rights retained. Servicing assets are initially recognized at fair value with the income statement effect recorded in gains on sales of loans and amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying financial asset. To determine the fair value of servicing rights, management uses a valuation model that calculates the present value of future cash flows. Assumptions used in the valuation model include market discount rates and anticipated prepayment speeds. In addition, estimates of the cost of servicing per loan, an inflation rate, ancillary income per loan, and default rates are used. The initial fair value relating to the servicing rights is capitalized and amortized into noninterest income in proportion to, and over the period of, estimated future net servicing income. Management assesses impairment of the mortgage servicing rights based on recalculations of the present value of remaining future cash flows using updated market discount rates and prepayment speeds. Subsequent loan prepayments and changes in prepayment assumptions in excess of those forecasted can adversely impact the carrying value of the servicing rights. Impairment is assessed on a stratified basis with any impairment recognized through a valuation allowance for each impaired stratum. The servicing rights are stratified based on the predominant risk characteristics of the underlying loans: fixed-rate loans and adjustable-rate loans. The effect of changes in market interest rates on estimated rates of loan prepayments is the predominant risk characteristic for mortgage servicing rights. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds, and default rates and losses. Mortgage servicing income represents fees earned for servicing loans. Fees for servicing mortgage loans are generally based upon a percentage of the principal balance of the loans serviced, as well as related ancillary income such as late charges. Servicing income is recognized as earned, unless collection is doubtful. The caption in the consolidated statement of income “ Mortgage servicing fees, net ” includes mortgage servicing income, amortization of mortgage servicing rights, the effects of mortgage servicing run-off, and impairment, if applicable.
Income taxes	Income taxes - First Federal accounts for income taxes in accordance with the provisions of ASC 740-10, Income Taxes , which requires the use of the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities are recognized for their future tax consequences, attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.
Premises and equipment	Premises and equipment - Premises and equipment are stated at cost less accumulated depreciation. Depreciation is recognized and computed on the straight-line method over the estimated useful lives as follows: Buildings 37.5 - 50 years Furniture, fixtures, and equipment 3 - 10 years Software 3 years Automobiles 5 years
Transfers of financial assets	Transfers of financial assets - Transfers of an entire financial asset, a group of financial assets, or a participating interest in an entire financial asset are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when: (1) the assets have been isolated from First Federal, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) First Federal does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. The mortgage loans that are sold with recourse provisions are accounted for as sales until such time as the loan defaults. Periodically, First Federal sells mortgage loans with “life of the loan” recourse provisions, requiring First Federal to repurchase the loan at any time if it defaults.
Bank-owned life insurance	Bank-owned life insurance - The carrying amount of life insurance approximates fair value. Fair value of life insurance is estimated using the cash surrender value, less applicable surrender charges. The change in cash surrender value is included in noninterest income.
Off-balance-sheet credit-related financial instruments	Off-balance-sheet credit-related financial instruments - In the ordinary course of business, First Federal has entered into commitments to extend credit, including commitments under lines of credit, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded when they are funded.
Advertising costs	Advertising costs - First Federal expenses advertising costs as they are incurred.
Comprehensive income (loss)	Comprehensive income (loss) - Accounting principles generally require that recognized revenue, expenses, and gains and losses be included in net income (loss) . Although certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale securities, are reported as a separate component of the equity section of the consolidated balance sheets, such items, along with net income (loss) , are components of comprehensive income (loss) .
Dividend restriction	Dividend restriction - Banking regulations require maintaining certain capital levels and may limit the dividends paid by the Bank to the Company or by the Company to shareholders.
Fair value measurements	Fair value measurements - Fair values of financial instruments are estimated using relevant market information and other assumptions ( Note 14 ). Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect these estimates.
Segment information	Segment information - First Federal is engaged in the business of attracting deposits and providing lending services. Substantially all income is derived from a diverse base of commercial, mortgage, and consumer lending activities and investments. The Company’s activities are considered to be a single industry segment for financial reporting purposes.
Employee Stock Ownership Plan	Employee Stock Ownership Plan - The cost of shares issued to the ESOP but not yet allocated to participants is shown as a reduction of shareholders' equity. Compensation expense is based on the market price of shares as they are committed to be released to participants' accounts. Dividends on allocated ESOP shares reduce retained earnings while dividends on unearned ESOP shares reduce debt and accrued interest.
Earnings (loss) per Share	Earnings (loss) per Share - Basic earnings (loss) per share ("EPS") is computed by dividing net income or (loss), reduced by earnings allocated to participating shares of restricted stock, by the weighted-average number of common shares outstanding during the period. As ESOP shares are committed to be released they become outstanding for EPS calculation purposes. ESOP shares not committed to be released are not considered outstanding for basic or diluted EPS calculations. The basic EPS calculation excludes the dilutive effect of all common stock equivalents. Diluted earnings per share reflects the weighted-average potential dilution that could occur if all potentially dilutive securities or other commitments to issue common stock were exercised or converted into common stock using the treasury stock method. According to the provisions of 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. At this time the Company has no share-based payment awards nor paid a dividend.
Recently issued accounting pronouncements	Recently issued accounting pronouncements Lease Accounting In February 2016, the FASB issued ASU No. 2016-02, Leases . ASU 2016-02 is intended to increase transparency and comparability among organizations by requiring the recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements. The principal change required by this ASU relates to lessee accounting, and is that for operating leases, a lessee is required to (1) recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statement of financial position, (2) recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term on a generally straight-line basis, and (3) classify all cash payments within operating activities in the statement of cash flows. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term. ASU 2016-02 also changes disclosure requirements related to leasing activities, and requires certain qualitative disclosures along with specific quantitative disclosures. The amendments in ASU 2016-02 are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018. Early application of the amendments in ASU 2016-02 is permitted. Once adopted, we expect to report higher assets and liabilities on our Consolidated Balance Sheets as a result of including right-of-use assets and lease liabilities related to certain banking offices and certain equipment under noncancelable operating lease agreements, which currently are not reflected in our Consolidated Balance Sheets. We do not expect the guidance to have a material impact on the Consolidated Statements of Income or Consolidated Statements of Changes in Shareholders' Equity. ASU 2016-02 initially provided for one retrospective transition method; however a second transition method was later added with ASU 2018-11 which permits companies to utilize certain practical expedients. In July 2018, FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases . These amendments provide minor clarifications and corrections to ASU 2016-02, Leases (Topic 842) . In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements . The amendments in this ASU provide entities with an additional optional transition method to adopt ASU 2016-02. Under this new transition method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity’s reporting under this additional transition method for the comparative periods presented in the financial statements in which it adopts the new leases standard would continue to be in accordance with current GAAP (Topic 840, Leases ). The Company adopted ASU 2016-02 (as amended by subsequent ASUs) effective January 1, 2019 utilizing the new transition method described in ASU 2018-11 and availed itself of practical expedients. As a lessee, the Company is party to several office leases for which the Company recorded right-of-use assets and lease liabilities at the present value of the remaining minimum rental payments of $3.9 million upon adoption of ASU 2016-02. As lessee, the Company applied the following practical expedients in the implementation ASU 2016-02: (i) to not separate non-lease components from the associated lease component as described above and (ii) to not apply the right-of-use recognition requirements to short-term leases. Other Accounting Topics In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Loss , which updates the guidance on recognition and measurement of credit losses for financial assets. The new requirements, known as the current expected credit loss model (CECL) will require entities to adopt an impairment model based on expected losses rather than incurred losses. ASU No. 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Upon adoption, the Company will change processes and procedures to calculate the allowance for loan losses, including changes in assumptions and estimates to consider expected credit losses over the life of the loan versus the current accounting practice that utilizes the incurred loss model. In addition, the current accounting policy and procedures for other-than-temporary impairment on investment securities available for sale will be replaced with an allowance approach. At this time, we cannot reasonably estimate the impact the implementation of this ASU will have on the Company's consolidated financial statements. The Company's internal project management team continues to review models, work with our third-party vendor, and discuss changes to processes and procedures to ensure the Company is fully compliant with the amendments at the adoption date. In August 2017, FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815). This ASU was issued to provide investors better insight to an entity’s risk management hedging strategies by permitting companies to recognize the economic results of its hedging strategies in its financial statements. The amendments in this ASU permit hedge accounting for hedging relationships involving non-financial 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. This ASU is effective for fiscal years beginning after December 15, 2018, and early adoption is permitted. Adoption of ASU 2017-12 is not expected to have a material impact on the Company’s consolidated financial statements. In June 2018, FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting . These amendments provide specific guidance for transactions for acquiring goods and services from nonemployees and specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (i) financing to the issuer or (ii) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers . This guidance is effective for fiscal years beginning after December 15, 2018, and interim periods beginning after December 15, 2020. Early adoption is permitted but not earlier than the adoption of Topic 606. The Company does not believe that this guidance will have a material effect on its consolidated financial statements as it has not historically issued share-based payments in exchange for goods or services to be consumed within its operations. In July 2018, FASB issued ASU No. 2018-09, Codification Improvements . These amendments provide clarifications and corrections to certain ASC subtopics including the following: 220-10 (Income Statement - Reporting Comprehensive Income - Overall), 470-50 (Debt - Modifications and Extinguishments), 480-10 (Distinguishing Liabilities from Equity - Overall), 718-740 (Compensation - Stock Compensation - Income Taxes), 805-740 (Business Combinations - Income Taxes), 815-10 (Derivatives and Hedging - Overall), and 820-10 (Fair Value Measurement - Overall). Some of the amendments in ASU 2018-09 do not require transition guidance and will be effective upon issuance; however, many of the amendments do have transition guidance with effective dates for annual periods beginning after December 15, 2018. The Company is currently assessing the impact this guidance will have on its consolidated financial statements. In August 2018, FASB issued ASU No. 2018-13, Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement which removes, modifies, and adds certain disclosure requirements related to fair value measurements in ASC 820. This guidance is effective for public companies in fiscal years beginning after December 15, 2019 with early adoption permitted. The Company is currently assessing the impact this guidance will have on its consolidated financial statements. In August 2018, FASB issued ASU No. 2018-15 Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract to provide guidance on implementation costs incurred in a cloud computing arrangement that is a service contract. The ASU aligns the accounting for such costs with the guidance on capitalizing costs associated with developing or obtaining internal-use software. Specifically, the ASU amends ASC 350 to include in its scope implementation costs of such arrangements that are service contracts and clarifies that a customer should apply ASC 350-40 to determine which implementation costs should be capitalized. This ASU, which is effective for fiscal years beginning after December 15, 2019, is not expected to have a material impact on the Company’s financial statements. In October 2018, the FASB issued ASU No. 2018-16 Derivatives and Hedging (Topic 815), Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes . The amendments in this ASU permit use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to the interest rates on direct Treasury obligations of the U.S. government, the London Interbank Offered Rate (LIBOR) swap rate, the Overnight Index Swap (OIS) Rate based on the Fed Funds Effective Rate and the Securities Industry and Financial Markets Association (SIFMA) Municipal Swap Rate. The amendments in this ASU are required to be adopted concurrently with the amendments in ASU 2017-12. For public companies, this would be for fiscal years, and interim periods within those fiscal years beginning after December 15, 2018. The Company is currently assessing the impact this guidance will have on its consolidated financial statements. In August 2018, the Securities and Exchange Commission issued a final rule that amends certain of its disclosure requirements. The rule simplifies various disclosure requirements for public companies including primarily that it (i) eliminates the requirement for public companies to disclose in their filings a schedule of earnings to fixed charges, (ii) requires an analysis of changes in stockholders’ equity for the current and comparative year-to-date interim periods in interim reports, and (iii) reduces the requirements for market price information disclosures in annual reports. These changes are effective for public companies beginning on November 5, 2018. The Company anticipates complying with these new requirements beginning with its March 31, 2019 Quarterly Report on Form 10-Q.
Reclassifications	Reclassifications - Certain amounts in the unaudited interim consolidated financial statements for prior periods have been reclassified to conform to the current audited financial statement presentation with no effect on net income or shareholders' equity.
