Basis of Presentation and Significant Accounting Policies [Text Block]	Note 1 - 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"). On December 18, 2015, the ESOP completed its open market purchases, with funds borrowed from the Company, of 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 is a community-oriented financial institution providing commercial and consumer banking services to individuals and businesses in Western Washington State with offices in Clallam, Jefferson, Kitsap, King, and Whatcom counties. These services include deposit and lending transactions that are supplemented with 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 year ended December 31, 2019. 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 and nine months ended September 30, 2020, are not necessarily indicative of the results that may be expected for future periods. 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"), fair value of financial instruments, and deferred tax assets and liabilities. Principles of consolidation - The accompanying consolidated financial statements include the accounts of First Northwest Bancorp and its wholly owned subsidiary, First Federal. All material intercompany accounts and transactions have been eliminated in consolidation. Subsequent Events - The Company has evaluated subsequent events for potential recognition and disclosure and has included additional information where appropriate. Recently adopted accounting pronouncements In August 2018, FASB issued ASU No. 2018-13, Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement, which removes, modifies, and adds certain disclosure requirements related to fair value measurements in ASC 820. This guidance eliminates certain disclosure requirements for fair value measurements: the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, an entity’s policy for the timing of transfers between levels of the fair value hierarchy and an entity’s valuation processes for Level 3 fair value measurements. This guidance also adds new disclosure requirements for public entities: changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements of instruments held at the end of the reporting period, and the range and weighted average of significant unobservable inputs used to develop recurring and nonrecurring Level 3 fair value measurements, including how the weighted average is calculated. Furthermore, this guidance modifies certain requirements which will involve disclosing: transfers into and out of Level 3 of the fair value hierarchy, purchases and issuances of Level 3 assets and liabilities, and information about the measurement uncertainty of Level 3 fair value measurements as of the reporting date. This guidance is effective for public companies in fiscal years beginning after December 15, 2019, with early adoption permitted. This ASU did not have a material impact on the Company's consolidated financial statements. In August 2018, FASB issued ASU No. 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, to provide guidance on implementation costs incurred in a cloud computing arrangement that is a service contract. The ASU aligns the accounting for such costs with the guidance on capitalizing costs associated with developing or obtaining internal-use software. Specifically, the ASU amends ASC 350 to include in its scope implementation costs of such arrangements that are service contracts and clarifies that a customer should apply ASC 350-40 to determine which implementation costs should be capitalized. This ASU, which is effective for fiscal years beginning after December 15, 2019, did not have a material impact on the Company’s financial statements. In March 2020, the FASB issued ASU No. 2020-03, Codification Improvements to Financial Instruments. The amendments represent clarification and improvements to the codification and correct unintended application. This standard was effective immediately upon issuance and its adoption did not have a material effect on the Company’s financial statements. Credit Losses 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. Additional updates were issued in ASU No. 2019-04, Codification Improvements to Topic 326,* Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging (Topic 825), Financial Instruments. This ASU clarifies and improves guidance related to the previously issued standards on credit losses, hedging and recognition and measurement of financial instruments. The amendments provide entities with various measurement alternatives and policy elections related to accounting for credit losses and accrued interest receivable balances. Entities are also able to elect a practical expedient to separately disclose the total amount of accrued interest included in the amortized cost basis as a single balance to meet certain disclosure requirements. The amendments clarify that the estimated allowance for credit losses should include all expected recoveries of financial assets and trade receivables that were previously written off and expected to be written off. The amendments also allow entities to use projections of future interest rate environments when using a discounted cash flow method to measure expected credit losses on variable-rate financial instruments. In addition, new updates were issued through ASU No.* 2019-05, Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief. This amendment allows entities to elect the fair value option on certain financial instruments. On adoption, an entity is allowed to irrevocably elect the fair value option on an instrument-by-instrument basis. This alternative is available for all instruments in the scope of Subtopic 326-20 except for existing held-to-maturity debt securities. If an entity elects the fair value option, the difference between the instrument’s fair value and carrying amount is recognized as a cumulative-effect adjustment. In November 2019, the FASB issued ASU 2019-10 which defers the effective date for this guidance for smaller reporting companies from the interim and annual periods beginning after December 15, 2020 to the interim and annual periods beginning after December 15, 2022. Early adoption is permitted for interim and annual periods beginning after December 15, 2018. The Company plans to defer adoption of CECL until January 1, 2023. The Company is evaluating the provisions of ASU No. 2016-13, ASU No. 2019-04 and ASU No. 2019-05, and will closely monitor developments and additional guidance to determine the potential impact on the Company’s consolidated financial statements. At this time, we cannot reasonably estimate the impact the implementation of these ASUs will have on the Company's consolidated financial statements. The Company's internal project management team continues to review models, work with our third-party vendor, and discuss changes to processes and procedures to ensure the Company is fully compliant with the amendments at the adoption date. Other Pronouncements In December 2019, FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. ASU 2019-12 simplifies various aspects related to accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The standard also clarifies and amends existing guidance to improve consistent application. This ASU, which is effective for fiscal years beginning after December 15, 2020, is not expected to have a material impact on the Company's financial statements. Early adoption is permitted. In January 2020, the FASB issued ASU No. 2020-01, Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)-Clarifying the Interactions between Topic 321, Topic 323, and Topic 815. ASU 2020-01 clarifies the interaction between accounting standards related to equity securities, equity method investments, and certain derivatives including accounting for the transition into and out of the equity method and measuring certain purchased options and forward contracts to acquire investments. The ASU, which is effective for fiscal years beginning after December 15, 2020, is not expected to have a material effect on the Company's financial statements. In March 2020, the FASB issued ASU No. 2020-04 Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ASU 2020-04 provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments are effective for the Company as of March 12, 2020 through December 31, 2022. The Company does not believe this standard will have a material impact on its 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.
