BASIS OF PRESENTATION
BASIS OF PRESENTATION	BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements were prepared in accordance with instructions for Quarterly Reports on Form 10-Q and, therefore, do not include all disclosures necessary for a complete presentation of financial condition, results of operations and cash flows in conformity with accounting principles generally accepted in the United States of America (“generally accepted accounting principles” or “GAAP”). However, all adjustments that are, in the opinion of management, necessary for a fair presentation of the interim unaudited consolidated financial statements have been included. All such adjustments are of a normal recurring nature. The accompanying unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Riverview Bancorp, Inc. Annual Report on Form 10-K for the year ended March 31, 2023 (“2023 Form 10-K”). The unaudited consolidated results of operations for the six months ended September 30, 2023 are not necessarily indicative of the results which may be expected for the entire fiscal year ending March 31, 2024. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Certain prior period amounts have been reclassified to conform to the current period presentation; such reclassifications had no effect on previously reported net income or total shareholders’ equity.
PRINCIPLES OF CONSOLIDATION	The accompanying consolidated financial statements include the accounts of Riverview Bancorp, Inc.; its wholly-owned subsidiary, Riverview Bank (the “Bank”); and the Bank’s wholly-owned subsidiaries, Riverview Services, Inc. and Riverview Trust Company (the “Trust Company”) (collectively referred to as the “Company”). All inter-company transactions and balances have been eliminated in consolidation. For the period from April 1, 2017 through December 2019, the Trust Company was a wholly-owned subsidiary of the Bank. In December 2019, the Trust Company issued 1,500 shares of Trust Company stock in conjunction with the exercise of 1,500 Trust Company stock options by the Trust Company’s President and Chief Executive Officer. In both October 2020 and May 2021, the Trust Company issued an additional 500 shares of Trust Company stock upon the exercise of options for 500 shares of Trust Company common stock by the Trust Company’s President and Chief Executive Officer. In August 2022, the Trust Company repurchased all the outstanding shares held by its noncontrolling interest owner. Upon repurchase, these shares were retired. This transaction resulted in the Bank’s ownership increasing from 97.3% to 100%. The book value of the noncontrolling interest was $234,000 prior to the share repurchase. These amounts were insignificant and are not presented separately in the accompanying consolidated financial statements.
NEW ACCOUNTING PRONOUNCEMENTS	Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments - Credit Losses (Topic 326) as amended by ASU 2018-19, ASU 2019-04 and ASU 2019-05, was originally issued by the Financial Accounting Standards Board (“FASB”) in June 2016. This ASU replaces the incurred loss methodology that delays recognition until it is probable a loss has been incurred with an expected loss methodology that is referred to as the CECL methodology. The amendments in this ASU require a financial asset that is measured at amortized cost to be presented at the net amount expected to be collected. The income statement would then reflect the measurement of credit losses for newly recognized financial assets as well as changes to the expected credit losses that have taken place during the reporting period. The measurement of expected credit losses will be based on historical information, current conditions, and reasonable and supportable forecasts that impact the collectability of the reported amount. Available-for-sale securities will bifurcate the fair value mark and establish an ACL for available-for-sale securities through the income statement for the credit portion of that mark. The adoption of CECL had an insignificant impact on the Company’s held to maturity and available for sale securities portfolios. The interest portion will continue to be recognized through accumulated other comprehensive income or loss. The change in the ACL recognized as a result of adoption will occur through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the ASU is adopted. This ASU is effective for smaller reporting companies, such as the Company, for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, with early adoption permitted. ASU 2019-05 issued in April 2019 further provides that entities that have certain financial instruments measured at amortized cost that has credit losses, to irrevocably elect the fair value option in Subtopic 825-10, upon adoption of ASU 2016-13. The fair value option applies to available-for-sale debt securities. This ASU is effective upon adoption of ASU 2016-13, and should be applied on a modified-retrospective basis as a cumulative-effect adjustment to the opening balance of retained earnings in the statement of financial condition as of the adoption date. On April 1, 2023, the Company adopted this ASU, which resulted in a net of tax charge of $53,000 to retained earnings, a $42,000 increase to ACL for loans, and a $28,000 increase to ACL for credit losses on unfunded commitments for the cumulative effect of adopting this guidance. In March 2022, the FASB issued ASU 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. This ASU eliminates the accounting guidance for TDRs by creditors while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Additionally, the ASU requires public business entities to disclose current-period gross write offs by year of origination for financial receivables and net investments in leases. This ASU is effective upon adoption of ASU 2016-13. On April 1, 2023, the Company adopted this ASU at the same time ASU 2016-13 was adopted. The Company had no loans modified to borrowers experiencing financial difficulty during the six months ended September 30, 2023. The Company had $11,000 in write offs from other installment loans and no recoveries for the six months ended September 30, 2023.
