Significant Accounting Policies
Basis of Presentation	Basis of Presentation The unaudited interim condensed consolidated financial statements included herein reflect all adjustments which are, in the opinion of management, necessary to present a fair statement of the results of operations for the interim periods presented. All such adjustments are of a normal, recurring nature. The condensed consolidated statement of financial condition at June 30, 2019 is derived from the audited consolidated financial statements of Provident Financial Holdings, Inc. and its wholly-owned subsidiary, Provident Savings Bank, F.S.B. (the "Bank") (collectively, the "Corporation"). Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been omitted pursuant to the rules and regulations of the United States Securities and Exchange Commission ("SEC") with respect to interim financial reporting. It is recommended that these unaudited interim condensed consolidated financial statements be read in conjunction with the audited consolidated financial statements and notes thereto included in the Corporation’s Annual Report on Form 10‑K for the year ended June 30, 2019. The results of operations for the quarter ended September 30, 2019 are not necessarily indicative of results that may be expected for the entire fiscal year ending June 30, 2020.
Accounting Standard Updates ("ASU")	Accounting Standard Updates (“ASU”) There have been no accounting standard updates or changes in the status of their adoption that are significant to the Corporation as previously disclosed in Note 1 of the Corporation's Annual Report on Form 10-K for the year ended June 30, 2019, other than: ASU 2016-13: In June 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-13, “Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” and subsequent amendment to the initial guidance in November 2018, ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, in April 2019, ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, and in May 2019, ASU 2019-05 Financial Instruments—Credit Losses, Topic 326, all of which clarifies codification and corrects unintended application of the guidance. These ASUs will be effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years assuming the adoption of an ASU implementing the FASB board decision in October 2019 extending the adoption date for certain registrants, including the Corporation. The Corporation is evaluating its current expected loss methodology of its loan and investment portfolios to identify the necessary modifications in accordance with these standards and expects a change in the 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. A valuation adjustment to its allowance for loan losses or investment portfolio that is identified in this process will be reflected as a one-time adjustment in equity rather than earnings upon adoption. The Corporation is in the process of compiling historical data that will be used to calculate expected credit losses on its loan portfolio to ensure the Corporation is fully compliant with these ASUs at the adoption date and is evaluating the potential impact adoption of this ASU will have on the Corporation’s Consolidated Financial Statements. ASU 2018-11 In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." This ASU introduces a lessee model that brings most leases onto the balance sheet and aligns many of the underlying principles of the new lessor model with those in the new revenue recognition standard, ASC 606, Revenue From Contracts With Customers. The new leases standard represents a wholesale change to lease accounting and did not result in significant implementation challenges during the transition period. 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. The effective date of this ASU for annual periods is beginning after December 15, 2018 (i.e., calendar periods beginning on January 1, 2019) and interim periods therein. In July 2018, the FASB issued ASU 2018-11, Leases, Targeted Improvements, which allows entities the option of initially applying the new leases standard at the adoption date (such as January 1, 2019, for calendar year- end public business entities) and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Corporation adopted the provisions of ASC 842 effective July 1, 2019 utilizing the transition method allowed under ASU 2018-11 and will not restate comparative periods as well as electing to not separate non-lease components from lease components. The Corporation elected the package of practical expedients permitted under ASC 842's transition guidance, which allows the Corporation to carryforward its historical lease classifications and its assessment as to whether a contract is or contains a lease. The Corporation also elected to not recognize lease assets and lease liabilities for leases with an initial term of 12 months or less. The adoption of ASC 842 did not have a material impact on its consolidated financial statements. See Note 10 for additional discussion. ASU 2018-13: In August 2018, the FASB issued ASU 2018-13, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which modifies disclosure requirements on fair value measurements to improve their effectiveness. The guidance permits entities to consider materiality when evaluating fair value measurement disclosures and, among other modifications, requires certain new disclosures related to Level 3 fair value measurements. The guidance will be effective beginning January 1, 2020, with early adoption permitted. The guidance only affects disclosures in the notes to the consolidated financial statements and will not otherwise affect the Corporation's Consolidated Financial Statements.
