Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Critical Accounting Policies	Basis of Presentation and Critical Accounting Policies Organization and Nature of business - First Northwest Bancorp, a Washington corporation, became the holding company of First Federal Savings and Loan Association of Port Angeles, on January 29, 2015, upon completion of the Bank's conversion from a mutual to stock form of organization (the "Conversion"). In connection with the Conversion, the Company issued an aggregate of 12,167,000 shares of common stock at an offering price of $10.00 per share for gross proceeds of $121.7 million . An additional 933,360 shares of Company common stock and $400,000 in cash were contributed to the First Federal Community Foundation ("Foundation"), a charitable foundation that was established in connection with the Conversion, resulting in the issuance of a total of 13,100,360 shares. The Company received $117.6 million in net proceeds from the stock offering of which $58.4 million were contributed to the Bank upon Conversion. Pursuant to the Bank's Plan of Conversion (the "Plan") adopted by its Board of Directors, and as approved by its members, the Company established an employee stock ownership plan ("ESOP") which purchased in the open market, with funds borrowed from the Company, 8% of the common stock issued in the Conversion for a total of 1,048,029 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 unaudited financial statements and related data, relates primarily to the Bank. The Bank provides commercial and consumer banking services to individuals and businesses located primarily on the Olympic Peninsula in the State of Washington. These services include deposit and lending transactions that are supplemented with other borrowing and investing activities. Basis of presentation - The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and footnotes required by U.S. Generally Accepted Accounting Principles ("GAAP") for complete financial statements. These unaudited interim consolidated financial statements should be read in conjunction with our audited consolidated financial statements and accompanying notes included in the Company's Annual Report on Form 10-K for the fiscal year ended June 30, 2016 . In our opinion, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation of the consolidated financial statements in accordance with GAAP have been included. Operating results for the three months ended September 30, 2016 , are not necessarily indicative of the results that may be expected for the year ended June 30, 2017 . In preparing the unaudited interim consolidated financial statements, we are required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to a determination of the allowance for loan losses ("ALLL"), mortgage servicing rights, fair value of financial instruments, deferred tax assets and liabilities, and the valuation of impaired loans. The Company completed its stock offering and became a public company on January 29, 2015 . The Conversion was accounted for as a change in corporate form with the historic basis of the Bank's assets, liabilities, and equity unchanged as a result. 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 ("Master Tenant"). 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. An initial equity contribution of $274,000 was made in September 2016 with a final contribution of $1.1 million due once a historic tax credit has been granted and all remaining items outlined in the agreement satisfied. All material intercompany accounts and transactions have been eliminated in consolidation. Subsequent Events - The Company has evaluated subsequent events for potential recognition and disclosure and determined there are no such events or transactions requiring recognition or disclosure. Recently issued accounting pronouncements - In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("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 Company has early-adopted this ASU. 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 will not have a material impact on the Company's consolidated financial statements. Reclassifications - Certain amounts in the unaudited interim consolidated financial statements for prior periods have been reclassified to conform to the current unaudited financial statement presentation with no effect on net income or shareholders' equity.

At September 30, 2016 , there were 17 investment securities with $954,000 of unrealized losses and a fair value of approximately $56.2 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 . We believe that the unrealized losses on our 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 three months ended September 30, 2016 or 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.

A loan is considered impaired when First Federal has determined that it may be unable to collect payments of principal or interest when due under the contractual terms of the loan. 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 troubled debt restructuring ("TDR") loans.

Federal regulations provide for the classification of lower quality loans and other assets, such as debt and equity securities, as substandard, doubtful, or loss; risk ratings 6, 7, and 8 in our 8-point risk rating system, respectively. 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 September 30, 2016 and June 30, 2016 , First Federal had $4.0 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.

A TDR is a loan to a borrower who is experiencing financial difficulty that has been modified from its original terms and conditions in such a way that First Federal is granting the borrower a concession of some kind. 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 TDR loan, First Federal classifies the loan as impaired for purposes of determining the allowance for loan losses. This requires the loan to initially 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. Certain qualifying TDR loans are subsequently measured for impairment using the factor for the corresponding segment and risk rating. 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.

Federal Taxes on Income

Income Tax Disclosure [Abstract]
Federal Taxes on Income	Federal Taxes on Income 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. Under current Federal income tax regulations, charitable contribution deductions are limited to 10% of taxable income. Due to this limitation, the Company currently has a valuation allowance of $1.9 million for financial statement reporting purposes related to its contribution to the Foundation. The contribution carryforward and related valuation allowance 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. The effective tax rates were 33.9% and 25.3% for the three months ended September 30, 2016 and 2015 , respectively. The Company's tax rate is reduced from the statutory tax rate in part as a result of permanent tax exclusions of noninterest income from bank-owned life insurance ("BOLI") and tax-exempt interest.

Earnings Per Share [Abstract]
Earnings per Share	Earnings per Share Basic earnings per share is 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. In addition, nonvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents are considered participating securities and are included in the computation of earnings per share. Certain of the Company's nonvested restricted stock awards qualify as participating securities. The following table presents a reconciliation of the components used to compute basic and diluted earnings per share for the three months ended September 30, 2016 and 2015 . Three Months Ended September 30, 2016 2015 Numerator: Net income $ 651 $ 1,228 Denominator: Basic weighted average common shares outstanding 11,647,106 12,144,859 Dilutive restricted stock grants 186,399 — Diluted weighted average common shares outstanding 11,833,505 12,144,859 Basic earnings per share $ 0.06 $ 0.10 Diluted earnings per share $ 0.06 $ 0.10 As of September 30, 2016 , the ESOP had purchased 1,048,029 shares in the open market. Unallocated shares are not included as outstanding for either basic or diluted earnings per share calculations. As of September 30, 2016 , there were 964,461 shares in the ESOP that remain unallocated.

Employee Benefits	Employee Benefits Employee Stock Ownership Plan In connection with the Conversion, the Company established an ESOP for eligible employees of the Company and the Bank. Employees of the Company and the Bank 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 issued in the Conversion for a total of 1,048,029 shares at an average price of $ 12.45 per share with funds borrowed from the Company. It is anticipated that the Bank will make contributions to the ESOP in amounts necessary to amortize the ESOP loan payable to the Company over a period of 20 years. At September 30, 2016 , the weighted average interest rate paid on the ESOP loan payable was 2.46% per annum. 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 annually 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. Payments of principal and interest are due annually on June 30 . No payment of principal or interest was made during the three months ended September 30, 2016 . 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 are recorded as a reduction of retained earnings; dividends on unallocated ESOP shares are recorded as a reduction of debt and accrued interest. Compensation expense related to the ESOP for the three months ended September 30, 2016 and 2015 was $195,000 and $148,000 , respectively. Shares held by the ESOP as of the dates indicated are as follows: September 30, 2016 June 30, 2016 (Dollars in thousands) Allocated shares 70,356 70,356 Committed to be released shares 13,212 — Unallocated shares 964,461 977,673 Total ESOP shares 1,048,029 1,048,029 Fair value of unallocated shares $ 13,011 $ 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 . Shares of common stock issued under the EIP may be authorized but unissued shares or repurchased shares. During the three months ended September 30, 2016 , 402,500 shares of restricted stock were awarded and no stock options were granted. There were no awards or related expenses during the three months ended September 30, 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. For the three months ended September 30, 2016 , total compensation expense for the EIP was $256,000 . The following table provides a summary of changes in non-vested restricted stock awards for the three months ended September 30, 2016 : For the Three Months Ended September 30, 2016 Weighted-Average Grant Date Shares Fair Value Non-vested at June 30, 2016 — Granted 402,500 $ 12.70 Vested — Forfeited (12,500 ) Non-vested at September 30, 2016 390,000 Expected to vest assuming a 3% forfeiture rate over the vesting term 378,300 As of September 30, 2016 , there was $4.8 million of total unrecognized compensation costs 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 4.75 years.

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 measured at fair value on a recurring basis at the dates indicated: September 30, 2016 Quoted Prices in or Liabilities Significant Inputs Significant Inputs (Level 1) (Level 2) (Level 3) Total (In thousands) Securities available-for-sale Municipal bonds $ — $ 22,873 $ — $ 22,873 Agency bonds — 10,038 — 10,038 ABS agency — 7,828 — 7,828 ABS corporate — 29,720 — 29,720 SBA — 9,109 — 9,109 MBS agency — 130,230 — 130,230 MBS corporate — 37,307 — 37,307 $ — $ 247,105 $ — $ 247,105 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 and liabilities 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. The following tables present the Company’s assets measured at fair value on a nonrecurring basis at the dates indicated: September 30, 2016 Level 1 Level 2 Level 3 Total (In thousands) Impaired loans $ — $ — $ 8,666 $ 8,666 Real estate owned and repossessed assets — — 131 131 $ — $ — $ 8,797 $ 8,797 June 30, 2016 Level 1 Level 2 Level 3 Total (In thousands) Impaired loans $ — $ — $ 9,072 $ 9,072 Real estate owned and repossessed assets — — 81 81 $ — $ — $ 9,153 $ 9,153 At September 30, 2016 and June 30, 2016 , there were no impaired loans with discounts to appraisal disposition value or other unobservable inputs.

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, 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 held for sale - The fair value of loans held for sale is based on quoted market prices from Federal Home Loan Mortgage Corporation ("Freddie Mac"), which are updated daily and represent prices at which loans are exchanged in high volumes and in a liquid market. 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 September 30, 2016 and June 30, 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	Basis of presentation - The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and footnotes required by U.S. Generally Accepted Accounting Principles ("GAAP") for complete financial statements. These unaudited interim consolidated financial statements should be read in conjunction with our audited consolidated financial statements and accompanying notes included in the Company's Annual Report on Form 10-K for the fiscal year ended June 30, 2016 . In our opinion, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation of the consolidated financial statements in accordance with GAAP have been included. Operating results for the three months ended September 30, 2016 , are not necessarily indicative of the results that may be expected for the year ended June 30, 2017 . In preparing the unaudited interim consolidated financial statements, we are required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to a determination of the allowance for loan losses ("ALLL"), mortgage servicing rights, fair value of financial instruments, deferred tax assets and liabilities, and the valuation of impaired loans. The Company completed its stock offering and became a public company on January 29, 2015 . The Conversion was accounted for as a change in corporate form with the historic basis of the Bank's assets, liabilities, and equity unchanged as a result.
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 ("Master Tenant"). 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. An initial equity contribution of $274,000 was made in September 2016 with a final contribution of $1.1 million due once a historic tax credit has been granted and all remaining items outlined in the agreement satisfied. All material intercompany accounts and transactions have been eliminated in consolidation.
Subsequent Events	Subsequent Events - The Company has evaluated subsequent events for potential recognition and disclosure and determined there are no such events or transactions requiring recognition or disclosure.
Recently issued accounting pronouncements	Recently issued accounting pronouncements - In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("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 Company has early-adopted this ASU. 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 will not have a material impact on the Company's consolidated financial statements.
Reclassifications	Reclassifications - Certain amounts in the unaudited interim consolidated financial statements for prior periods have been reclassified to conform to the current unaudited financial statement presentation with no effect on net income or shareholders' equity.
