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"), was formed in connection with the conversion of First Federal Savings and Loan Association of Port Angeles ("First Federal" or the "Bank") from the mutual to the stock form of organization. First Northwest and the Bank are collectively referred to as the "Company." The conversion and the Company's initial stock offering were completed January 29, 2015 , through the sale and issuance of 12,167,000 shares of common stock of the Company at a price of $10.00 per share in a subscription offering. 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. 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 provides commercial and consumer banking services to individuals and businesses in our primary market area and have expanded our lending activities to other regions of western Washington State in order to diversify our loan portfolio and increase our net interest margin. These services include deposit and lending transactions that are supplemented with borrowing and investing activities. Plan of conversion and change in corporate form - On January 29, 2015 , in accordance with a Plan of Conversion (Plan) adopted by its Board of Directors and as approved by its members, the Bank converted from a mutual savings bank to a stock savings bank and became the wholly-owned subsidiary of First Northwest, a bank holding company registered with the Board of Governors of the Federal Reserve System ("Federal Reserve"). Deferred conversion costs of $4.1 million were deducted from the proceeds of the shares sold in the offering during the third quarter of fiscal year 2015. The net proceeds of the issuance of capital stock were $117.6 million . From the net proceeds, First Northwest made a capital contribution of $58.4 million to the Bank and a $400,000 cash contribution to the Foundation. Pursuant to the Plan, 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 June 30, 2017 , 1,048,029 shares, or 100.0% of the total, had been purchased. As of June 30, 2017 , First Northwest has allocated 121,695 shares from the total shares purchased to participants. 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 will be maintained for the benefit of eligible depositors who continue to maintain their accounts at the Bank after the conversion. The liquidation account will be 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. 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, mortgage servicing rights, fair value of financial instruments, deferred tax assets and liabilities, and the valuation of impaired loans. The conversion has been accounted for as a change in corporate form with the historic basis of the Bank's assets, liabilities, and equity unchanged. Principles of consolidation - The accompanying consolidated financial statements include the accounts of First Northwest Bancorp; its wholly owned subsidiary, First Federal; and First Federal's wholly owned subsidiary, North Olympic Peninsula Services, Inc. ("NOPS"), majority-owned Craft3 Development IV, LLC ("Craft3"), and majority-owned 202 Master Tenant, LLC. NOPS was dissolved on February 12, 2016, at which time the building owned by NOPS and rented in whole to First Federal became the property of the Bank. Craft3 is a partnership investment formed to provide a loan qualifying under the New Markets Tax Credit ("NMTC") rules. The Craft3 partnership was a seven year commitment, commensurate with the NMTC period, which expired June 6, 2015. First Federal subsequently entered a membership redemption and assignment agreement which terminated its membership interest in the Craft3 partnership effective September 30, 2015. In August 2016, First Federal entered into a partnership with the Peninsula College Foundation forming 202 Master Tenant, LLC, in order to receive a historic tax credit. This investment meets the criteria for reporting under the equity method of accounting. All material intercompany accounts and transactions have been eliminated in consolidation. Subsequent events - The Company has evaluated subsequent events for potential recognition and 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 $8.8 million and $6.7 million at June 30, 2017 and 2016 , respectively. First Federal was in compliance with its reserve requirements at June 30, 2017 and 2016 . 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 June 30, 2017 or 2016 . 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 June 30, 2017 and 2016 , First Federal’s minimum investment requirement was approximately $4.4 million . First Federal was in compliance with the FHLB minimum investment requirement at June 30, 2017 and 2016 . 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 June 30, 2017 and 2016 . 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. At the time of foreclosure, foreclosed real estate is recorded at the fair value less estimated costs to sell, which becomes the property’s new cost basis. Any write-downs based on the asset’s fair value at date of acquisition are charged to the allowance for loan losses. After foreclosure, valuations are periodically performed by management and property held for sale is carried at the lower of the new cost basis or fair value less estimated costs to sell. Impairment losses on property to be held and used are measured as the amount by which the carrying amount of a property exceeds its fair value. Subsequent gains, losses, and expenses recognized on the sale of these properties are included in noninterest expense. The amounts ultimately recovered on foreclosed assets may differ substantially from the carrying value of the assets due to future market factors beyond management's control. 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 on the consolidated balance sheets 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 operations “ Mortgage servicing fees, net ” includes mortgage servicing income, amortization of mortgage servicing rights, the effects of mortgage servicing run-off, and impairment. 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 June 30, 2017 and 2016 , was approximately $6.5 million and $7.2 million , respectively. Of these loans, one loan was repurchased for $100,000 during the year ended June 30, 2017 . Two loans were also repurchased in the amount of $151,000 during the year ended June 30, 2016 . There is an associated allowance of $33,000 and $57,000 at June 30, 2017 and 2016 , 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. An additional $10.0 million of life insurance was purchased in August 2016. 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) . 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 issued accounting pronouncements - In August 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2015-14, Revenue from Contracts with Customers (Topic 606) , which defers the effective date of ASU No. 2014-09 one year. ASU No. 2014-09 created Topic 606 and supersedes Topic 605, Revenue Recognition. The core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. 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. ASU No. 2015-14 is effective for public entities for interim and annual periods beginning after December 15, 2017; early adoption is permitted for interim and annual periods beginning after December 15, 2016.

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 . At June 30, 2016 , there were 15 investment securities with $1.3 million of unrealized losses and a fair value of approximately $65.6 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 years ended June 30, 2017 , 2016 and 2015 . 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.

In the process of identifying loans as impaired, management takes into consideration factors that include payment history and status, collateral value, financial condition of the borrower, and the probability of collecting scheduled payments in the future. Minor payment delays and insignificant payment shortfalls typically do not result in a loan being classified as impaired. The significance of payment delays and shortfalls is considered by management on a case-by-case basis after taking into consideration the totality of circumstances surrounding the loans and the borrowers, including payment history and amounts of any payment shortfall, length and reason for delay, and likelihood of return to stable performance. Impairment is measured on a loan-by-loan basis for all loans in the portfolio except smaller balance homogeneous loans and certain qualifying TDR loans.

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. At June 30, 2017 and June 30, 2016 , First Federal had $3.3 million and $4.6 million , respectively, of loans classified as substandard and no loans classified as doubtful or loss. 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.

First Federal has granted a variety of concessions to borrowers in the form of loan modifications. The modifications granted can generally be described in the following categories: Rate modification - A modification in which the interest rate is changed. Term modification - A modification in which the maturity date, timing of payments, or frequency of payments is changed. Payment modification - A modification in which the dollar amount of the payment is changed. Interest-only modifications in which a loan is converted to interest-only payments for a period of time are included in this category. Combination modification - Any other type of modification, including the use of multiple categories above. Upon identifying a receivable as a troubled debt restructuring, First Federal classifies the loan as impaired for purposes of determining the allowance for loan losses. This requires the loan to be evaluated individually for impairment, generally based on the expected cash flows under the new terms discounted at the loan’s original effective interest rates. For TDR loans that subsequently default, the method of determining impairment is generally the fair value of the collateral less estimated selling costs. The following is a summary of information pertaining to TDR loans included in impaired loans at the dates indicated: June 30, 2017 2016 (In thousands) Total TDR loans $ 6,145 $ 6,545 Allowance for loan losses related to TDR loans 315 267 Total nonaccrual TDR loans 673 944 The following table presents newly restructured and renewals or modifications of existing TDR loans by class that occurred during the year ended June 30, 2017 , by type of concession granted: Number of Contracts Rate Modification Term Modification Combination Total Modifications (Dollars in thousands) Pre-modification outstanding recorded investment One- to four-family 3 $ 95 $ 89 $ 244 $ 428 Commercial real estate 1 — — 134 134 4 $ 95 $ 89 $ 378 $ 562 Post-modification outstanding recorded investment One- to four-family 3 $ 92 $ 87 $ 236 $ 415 Commercial real estate 1 — — 129 129 4 $ 92 $ 87 $ 365 $ 544 The following is a summary of TDR loans which incurred a payment default within 12 months of the restructure date during the year ended June 30, 2017 .

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.

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 June 30, 2017 , the balance of the contribution carryforward totaled $8.0 million . The contribution carryforward will expire in 2020. 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 $1.9 million at both June 30, 2017 and 2016 . 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 June 30, 2017 and June 30, 2016 . During the years ended June 30, 2017 and 2016 , 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, 2014 . The components of net deferred tax assets and liabilities at June 30 are summarized as follows: 2017 2016 (In thousands) Deferred tax assets Allowance for loan losses $ 2,957 $ 2,527 Unrealized loss on securities available for sale 238 — Accrued compensation 952 535 Nonaccrual loans 6 15 Real estate owned — 36 ESOP timing differences 111 69 Restricted stock awards 332 — Contribution carryforward 2,716 2,976 Total deferred tax assets 7,312 6,158 Deferred tax liabilities Deferred loan fees 474 537 Unrealized gain on securities available for sale — 960 FHLB stock dividends 801 807 Accumulated depreciation 1,249 1,281 Deferred investment gain 11 — Other, net 24 152 Total deferred tax liabilities 2,559 3,737 Deferred tax asset, net 4,753 2,421 Deferred tax asset valuation allowance (1,898 ) (1,917 ) Deferred tax asset, net of valuation allowance $ 2,855 $ 504

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: 2016 2015 Source Valuation Report Valuation Report Our plan 106.3% 106.8% There was no change to the funded status of the plan as of June 30, 2017 . 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 years ended June 30 were: 2017 2016 2015 Date Paid Amount Date Paid Amount Date Paid Amount (In thousands) 10/12/2016 $ 75 10/14/2015 $ 74 12/26/2014 $ 700 12/19/2016 524 1/4/2016 425 $ 599 $ 499 $ 700 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 June 30, 2017 , was $566,000 . 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 During the year ended June 30, 1994, First Federal began participation in a multi-employer 401(k) plan funded by employees and a Bank matching program. In December 2012, the Plan converted to a single-employer 401(k) plan. Beginning July 1, 2015, employees may contribute up to 100% of their pre-tax compensation to the 401(k) plan, an increase from the 20% limitation in prior plan years. First Federal provides matching funds of 50% limited to the first 6% of salary contributed. First Federal's contributions were $177,000 , $159,000 , and $163,000 during the years ended June 30, 2017 , 2016 , and 2015 , 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 June 30, 2017 , 1,048,029 shares, or 100.0% 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 and $810,000 , and $274,000 , were made by the ESOP during the years ended June 30, 2017 , 2016 , and 2015 , respectively. 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 years ended June 30, 2017 , 2016 , and 2015 , was $763,000 , $677,000 and $216,000 , respectively. Shares held by the ESOP as of the dates indicated are as follows: June 30, 2017 June 30, 2016 (Dollars in thousands) Allocated shares 121,695 70,356 Unallocated shares 926,334 977,673 Total ESOP shares 1,048,029 1,048,029 Fair value of unallocated shares $ 14,608 $ 12,456 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 June 30, 2017 , 402,500 shares of restricted stock were awarded and no stock options were granted. There were no awards or related expenses during years ended June 30, 2016 and 2015 . 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. On July 7, 2017 , the Company reissued 50,000 shares of common stock and granted them as restricted share awards to certain employees pursuant to the EIP. The restricted shares will vest in equal installments of 20% per year over a five -year period. For the year ended June 30, 2017 , total compensation expense for the EIP was $977,000 . Included in the above compensation expense for the year ended June 30, 2017 , was directors' compensation of $383,000 . The following table provides a summary of changes in non-vested restricted stock awards for the year ended June 30, 2017 : For the Year Ended June 30, 2017 Weighted-Average Grant Date Shares Fair Value Non-vested at July 1, 2016 — Granted 402,500 $ 12.70 Vested — Forfeited (12,500 ) 12.70 Non-vested at June 30, 2017 390,000 Expected to vest assuming a 3% forfeiture rate over the vesting term 378,300 As of June 30, 2017 , there was $4.0 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 4 years .

Regulatory Capital Requirements

Regulatory Capital Requirements	12 Months Ended
	Jun. 30, 2017
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), the Bank is 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. The Bank is required to maintain additional levels of Tier 1 common equity over the minimum risk-based capital levels before it may pay dividends, repurchase shares or pay 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 addition to the minimum CET1, Tier 1 and total capital ratios, the Bank has to maintain a capital conservation buffer consisting of additional CET1 capital above the required minimum levels 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. This new capital conservation buffer requirement was phased in starting in January 2016 at 0.625% of risk-weighted assets and will increase each year until fully implemented to an amount equal to 2.5% of risk-weighted assets in January 2019. As of June 30, 2017, the conservation buffer was 1.25% . 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 June 30, 2017 , 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 June 30, 2017 , First Northwest and First Federal each exceeded all regulatory capital requirements.

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 years ended June 30, 2017 and 2016 . The following financial instruments were outstanding whose contract amounts represent credit risk at June 30 : 2017 2016 (In thousands) Commitments to grant loans $ 670 $ 1,111 Standby letters of credit 183 401 Unfunded commitments under lines of credit or existing loans 67,800 65,151 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 June 30, 2017 and 2016 , First Federal’s most significant concentration of credit risk was in loans secured by real estate. These loans totaled approximately $697.5 million and $600.0 million , or 95.0% and 95.9% , of First Federal’s total loan portfolio at June 30, 2017 and 2016 , 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 June 30, 2017 and 2016 , 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 $238.7 million and $261.3 million , or 83.8% and 79.6% , of First Federal’s total investment portfolio (including FHLB stock) at June 30, 2017 and 2016 , 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: June 30, 2017 Quoted Prices in or Liabilities Significant Inputs Significant Inputs (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 June 30, 2016 Quoted Prices in Significant Significant (Level 1) (Level 2) (Level 3) Total (In thousands) Securities available for sale Municipal bonds $ — $ 23,179 $ — $ 23,179 Agency bonds 15,048 — 15,048 ABS agency — 7,935 — 7,935 ABS corporate 29,381 — 29,381 SBA — 9,501 — 9,501 MBS agency — 141,649 — 141,649 MBS corporate 41,164 — 41,164 $ — $ 267,857 $ — $ 267,857 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.

Estimated fair values require subjective judgments and are approximate. The estimates of fair value in the previous table are not necessarily representative of amounts that could be realized in actual market transactions, or of the underlying value of the Company. Fair value estimates, methods, and assumptions are set forth below for the Company's financial instruments: Financial instruments with book value equal to fair value - The fair value of financial instruments that are short-term or reprice frequently and that have little or no risk are considered to have a fair value equal to book value. These instruments include cash and due from banks, interest bearing deposits with banks, loans held for sale, FHLB stock, accrued interest receivable, and accrued interest payable. FHLB stock is not publicly traded, however, it may be redeemed on a dollar-for-dollar basis, for any amount the Bank is not required to hold, subject to the FHLB's discretion. The fair value is therefore equal to the book value. Securities - Fair values for investment securities are primarily measured using information from a third-party pricing service. The pricing service uses evaluated pricing models based on market data. In the event that limited or less transparent information is provided by the third-party pricing service, fair value is estimated using secondary pricing services or non-binding third-party broker quotes. Loans receivable, net - Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type, including fixed and variable one- to four-family residential real estate, commercial, and consumer loans. There is an accurate and reliable secondary market for one- to four-family residential mortgage production, and available market benchmarks are used to establish discount factors for estimating fair value for these types of loans. Commercial and consumer loans use market benchmarks when available; however, due to the varied term structures and credit issues involved, they mainly rely on cash flow projections and repricing characteristics within the loan portfolio. These amounts are discounted further by embedded probable losses expected to be realized in the portfolio. Valuations of impaired loans, real estate owned and repossessed assets are periodically performed by management, and the fair values of these loans are carried at the fair value of the underlying collateral less estimated costs to sell. Fair value of the underlying collateral may be determined using an appraisal performed by a qualified independent appraiser. Mortgage servicing rights - The estimated fair value of mortgage servicing rights is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. Deposits - The fair value of deposits with no stated maturity, such as non-interest bearing deposits, savings and interest checking accounts, and money market accounts, is equal to the amount payable on demand as of June 30, 2017 and 2016 . The fair value of certificates of deposit is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities. Borrowings - The fair value of FHLB advances and other borrowings are calculated using a discounted cash flow method, adjusted for market interest rates and terms to maturity. Off-balance-sheet financial instruments - Commitments to extend credit represent all off-balance-sheet financial instruments. The fair value of these commitments is not significant.

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. Basic and diluted earnings per share are the same amount at June 30, 2017 as the Company does not have any additional potential dilutive common shares. The following table presents a reconciliation of the components used to compute basic and diluted earnings (loss) per share for the periods shown.

Summary of Significant Accoun27

Summary of Significant Accounting Policies - (Policies)	12 Months Ended
	Jun. 30, 2017
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, mortgage servicing rights, fair value of financial instruments, deferred tax assets and liabilities, and the valuation of impaired loans. The conversion has been accounted for as a change in corporate form with the historic basis of the Bank's assets, liabilities, and equity unchanged.
Principles of consolidation	Principles of consolidation - The accompanying consolidated financial statements include the accounts of First Northwest Bancorp; its wholly owned subsidiary, First Federal; and First Federal's wholly owned subsidiary, North Olympic Peninsula Services, Inc. ("NOPS"), majority-owned Craft3 Development IV, LLC ("Craft3"), and majority-owned 202 Master Tenant, LLC. NOPS was dissolved on February 12, 2016, at which time the building owned by NOPS and rented in whole to First Federal became the property of the Bank. Craft3 is a partnership investment formed to provide a loan qualifying under the New Markets Tax Credit ("NMTC") rules. The Craft3 partnership was a seven year commitment, commensurate with the NMTC period, which expired June 6, 2015. First Federal subsequently entered a membership redemption and assignment agreement which terminated its membership interest in the Craft3 partnership effective September 30, 2015. In August 2016, First Federal entered into a partnership with the Peninsula College Foundation forming 202 Master Tenant, LLC, in order to receive a historic tax credit. This investment meets the criteria for reporting under the equity method of accounting. 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.
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 June 30, 2017 or 2016 . 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 June 30, 2017 and 2016 , First Federal’s minimum investment requirement was approximately $4.4 million . First Federal was in compliance with the FHLB minimum investment requirement at June 30, 2017 and 2016 . 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 June 30, 2017 and 2016 .
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. At the time of foreclosure, foreclosed real estate is recorded at the fair value less estimated costs to sell, which becomes the property’s new cost basis. Any write-downs based on the asset’s fair value at date of acquisition are charged to the allowance for loan losses. After foreclosure, valuations are periodically performed by management and property held for sale is carried at the lower of the new cost basis or fair value less estimated costs to sell. Impairment losses on property to be held and used are measured as the amount by which the carrying amount of a property exceeds its fair value. Subsequent gains, losses, and expenses recognized on the sale of these properties are included in noninterest expense. The amounts ultimately recovered on foreclosed assets may differ substantially from the carrying value of the assets due to future market factors beyond management's control.
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 on the consolidated balance sheets 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 operations “ Mortgage servicing fees, net ” includes mortgage servicing income, amortization of mortgage servicing rights, the effects of mortgage servicing run-off, and impairment.
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) .
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 - In August 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2015-14, Revenue from Contracts with Customers (Topic 606) , which defers the effective date of ASU No. 2014-09 one year. ASU No. 2014-09 created Topic 606 and supersedes Topic 605, Revenue Recognition. The core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. 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. ASU No. 2015-14 is effective for public entities for interim and annual periods beginning after December 15, 2017; early adoption is permitted for interim and annual periods beginning after December 15, 2016. For financial reporting purposes, the standard allows for either full retrospective adoption, meaning the standard is applied to all of the periods presented, or modified retrospective adoption, meaning the standard is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the standard recognized at the date of initial application. A significant amount of the Company’s revenues are derived from net interest income on financial assets and liabilities, which are excluded from the scope of the amended guidance. With respect to noninterest income, the Company anticipates completing the review of revenue streams and underlying revenue contracts within the scope of the guidance no later than November 2017. The Company will develop processes and procedures as a component of the review project to ensure it is fully compliant with these amendments. To date, the Company has not yet identified any significant changes in the timing of revenue recognition when considering the amended accounting guidance; however, the Company’s implementation efforts are ongoing and such assessments may change prior to the January 1, 2018 implementation date. In January 2016, the FASB issued ASU 2016-01, Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities . The main provisions of this ASU address the valuation and impairment of equity securities along with enhanced disclosures about those investments. Equity securities with readily determinable fair values will be treated in the same manner as other financial instruments. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of ASU 2016-01 is not expected to have a material impact on the Company's consolidated financial statements. In February 2016, the FASB issued ASU 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. The Company expects to compile an inventory of all leased assets to determine the impact of ASU 2016-02 on its financial condition and results of operations. 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. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting . This ASU includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. ASU 2016-09 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2016. The adoption of this ASU did not have a material impact on the Company's consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit 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 do not anticipate an increase to the ALLL as a result of the implementation of this ASU. The Company continues to review the requirements of ASU 2016-13 and has reviewed preliminary testing of processes and procedures to ensure it is fully compliant with the amendments at the adoption date. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . The ASU provides specific guidance on eight classification issues in order to achieve more consistent reporting. The amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted. The adoption of ASU No. 2016-15 is not expected to have a material impact on the Company's consolidated financial statements. In January 2017, the FASB issued ASU 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments-Equity Method and Joint Ventures (Topic 323) . This ASU amends the Codification for SEC staff announcements made at recent Emerging Issues Task Force (EITF) meetings. The SEC staff view is that a registrant should evaluate ASU updates that have not yet been adopted to determine the appropriate financial disclosures about the potential material effects of the ASU on the financial statements when adopted. If a registrant does not know or cannot reasonably estimate the impact of an ASU, then in addition to making a statement to that effect, the registrant should consider additional qualitative financial statement disclosures to assist the reader in assessing the significance of the impact. The staff expects the additional qualitative disclosures to include a description of the effect of the accounting policies expected to be applied compared to current accounting policies. Also, the registrant should describe the status of its process to implement the new standards and the significant implementation matters yet to be addressed. The amendments specifically addressed recent FASB guidance as well as any amendments issued prior to adoption, on revenue (ASU 2014-09), leases (ASU 2016-02) and credit losses on financial instruments (ASU 2016-13). The Company has adopted the amendments in this ASU and appropriate disclosures have been included in this Note. In March 2017, the FASB issued ASU 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities . The ASU shortens the amortization period for certain callable debt securities held at a premium using the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2019. Early adoption is permitted. The adoption of ASU No. 2017-08 is not expected to have a material impact on the Company's consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting . This ASU provides clarity on the guidance related to stock compensation when there have been changes to the terms or conditions of a share-based payment award to which an entity would be required to apply modification accounting under ASC 718. The ASU provides the three following criteria must be met in order to not account for the effect of the modification of terms or conditions: the fair value, the vesting conditions and the classification as an equity or liability instrument of the modified award is the same as the original award immediately before the original award is modified. The amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted. The adoption of ASU No. 2017-09 is not expected to have a material impact on the Company's consolidated financial statements.
