BASIS OF PRESENTATION
BASIS OF PRESENTATION	1. 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, 2022 (“2022 Form 10-K”). The unaudited consolidated results of operations for the three months ended June 30, 2022 are not necessarily indicative of the results which may be expected for the entire fiscal year ending March 31, 2023. ​ 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
PRINCIPLES OF CONSOLIDATION	2. PRINCIPLES OF CONSOLIDATION The accompanying consolidated financial statements include the accounts of Riverview Bancorp, Inc.; its wholly-owned subsidiary, Riverview Community Bank (the “Bank”); the Bank’s wholly-owned subsidiary, Riverview Services, Inc., and the Bank’s majority-owned subsidiary, Riverview Trust Company (the “Trust Company”) (collectively referred to as the “Company”). All intercompany 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. As a result of these transactions, the Bank's ownership in the Trust Company decreased from 100% to 97.3%, resulting in a 2.7% noncontrolling interest held by the Trust Company’s President and Chief Executive Officer. The noncontrolling interest was $213,000 and $212,000 as of June 30, 2022 and March 31, 2022, respectively. Net income attributable to the noncontrolling interest was $2,000 for both the three months ended June 30, 2022 and 2021. These amounts are not presented separately in the accompanying consolidated financial statements due to their insignificance.

STOCK PLANS AND STOCK-BASED COMPENSATION
STOCK PLANS AND STOCK-BASED COMPENSATION	3. STOCK PLANS AND STOCK-BASED COMPENSATION Stock Option Plans - In July 2003, shareholders of the Company approved the adoption of the 2003 Stock Option Plan (“2003 Plan”). The 2003 Plan was effective in July 2003 and expired in July 2013. Accordingly, no further option awards may be granted under the 2003 Plan; however, any awards granted prior to their respective expiration dates remain outstanding subject to their terms. Each option granted under the 2003 Plan has an exercise price equal to the fair value of the Company’s common stock on the date of the grant, a maximum term of ten years and a vesting period from zero to five years . ​ In July 2017, the shareholders of the Company approved the Riverview Bancorp, Inc. 2017 Equity Incentive Plan (“2017 Plan”). The 2017 Plan provides for the grant of incentive stock options, non-qualified stock options, restricted stock and restricted stock units. The Company has reserved 1,800,000 shares of its common stock for issuance under the 2017 Plan. The 2003 Plan and the 2017 Plan are collectively referred to as “the Stock Option Plans”. ​ The fair value of each stock option granted is estimated on the date of grant using the Black-Scholes stock option valuation model. The fair value of all awards is amortized on a straight-line basis over the requisite service periods, which are generally the vesting periods. The expected life of options granted represents the period of time that they are expected to be outstanding. The expected life is determined based on historical experience with similar options, giving consideration to the contractual terms and vesting schedules. Expected volatility is estimated at the date of grant based on the historical volatility of the Company's common stock. Expected dividends are based on dividend trends and the market value of the Company's common stock at the time of grant. The risk-free interest rate for periods within the contractual life of the options is based on the U.S. Treasury yield curve in effect at the time of the grant. There were no stock options granted under the 2017 Stock Option Plan during the three months ended June 30, 2022 and 2021. ​ As of June 30, 2022, all outstanding stock options were fully vested and there was no remaining unrecognized compensation expense related to stock options granted under the Stock Option Plans. There was no stock-based compensation expense related to stock options for the three months ended June 30, 2022 and 2021 under the Stock Option Plans. ​ The following table presents the activity related to stock options under the Stock Option Plans for the periods shown: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended June 30, ​ Three Months Ended June 30, ​ ​ 2022 ​ 2021 ​ ​ Weighted ​ Weighted ​ ​ ​ ​ Average ​ ​ ​ Average ​ ​ ​ Number of ​ Exercise ​ Number of ​ Exercise ​ ​ Shares Price Shares Price Balance, beginning of period 17,332 ​ $ 2.78 23,332 ​ $ 2.78 Options exercised (1,511) ​ 2.78 — ​ — Balance, end of period 15,821 ​ $ 2.78 23,332 ​ $ 2.78 ​ The following table presents information on stock options outstanding, less estimated forfeitures, as of June 30, 2022 and 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2022 ​ 2021 ​ Stock options fully vested and expected to vest: ​ ​ ​ Number ​ 15,821 ​ 23,332 ​ Weighted average exercise price ​ $ 2.78 ​ $ 2.78 ​ Aggregate intrinsic value (1) ​ $ 60,000 ​ $ 101,000 ​ Weighted average contractual term of options (years) ​ 1.04 ​ 2.04 ​ Stock options fully vested and currently exercisable: ​ ​ ​ ​ ​ Number ​ 15,821 ​ 23,332 ​ Weighted average exercise price ​ $ 2.78 ​ $ 2.78 ​ Aggregate intrinsic value (1) ​ $ 60,000 ​ $ 101,000 ​ Weighted average contractual term of options (years) ​ 1.04 ​ 2.04 ​ ​ (1) The aggregate intrinsic value of a stock option in the table above represents the total pre-tax intrinsic value (the amount by which the current market value of the underlying stock exceeds the exercise price) that would have been received by the option holders had all option holders exercised. This amount changes based on changes in the market value of the Company’s stock. The total intrinsic value of stock options exercised was $7,000 for the three months ended June 30, 2022 under the Stock Option Plans. There were no stock options exercised for the three months ended June 30, 2021 under the Stock Option Plans. ​ The Company may grant restricted stock pursuant to the 2017 Plan of which vesting can either be time based or performance based. Performance based awards are subject to attaining certain performance metrics and all, or a portion of, the performance based awards can subsequently be cancelled for not attaining the predetermined performance metrics. The fair value of restricted stock awards is equal to the fair value of the Company’s stock on the date of grant. The related stock-based compensation expense is recorded over the requisite service period. Stock-based compensation related to restricted stock grants was $63,000 and $55,000 for the three months ended June 30, 2022 and 2021, respectively. The unrecognized stock-based compensation related to restricted stock was $316,000 and $293,000 at June 30, 2022 and 2021, respectively. The weighted average vesting period for the restricted stock was 1.27 years and 1.38 years at June 30, 2022 and 2021, respectively. ​ The following tables presents the activity related to restricted stock for the periods shown: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Time Based Performance Based Total ​ ​ Number ​ Weighted ​ Number ​ Weighted ​ Number ​ Weighted ​ ​ of ​ Average ​ of ​ Average ​ of ​ Average ​ ​ Unvested ​ Grant Date ​ Unvested ​ Grant Date ​ Unvested ​ Grant Date Three Months Ended June 30, 2022 Shares Fair Value Shares Fair Value Shares Fair Value Balance, beginning of period 26,855 ​ $ 6.02 121,492 ​ $ 5.70 148,347 ​ $ 5.76 Forfeited — ​ — (2,977) ​ 7.56 (2,977) ​ 7.56 Vested (2,517) ​ 8.35 (10,968) ​ 8.35 (13,485) ​ 8.35 Balance, end of period 24,338 ​ $ 5.78 107,547 ​ $ 5.38 131,885 ​ $ 5.45 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Time Based Performance Based Total ​ ​ Number ​ Weighted ​ Number ​ Weighted ​ Number ​ Weighted ​ ​ of ​ Average ​ of ​ Average ​ of ​ Average ​ ​ Unvested ​ Grant Date ​ Unvested ​ Grant Date ​ Unvested ​ Grant Date Three Months Ended June 30, 2021 Shares Fair Value Shares Fair Value Shares Fair Value Balance, beginning of period 45,616 ​ $ 6.57 96,772 ​ $ 5.27 142,388 ​ $ 5.69 Vested (23,133) ​ 8.35 (12,732) ​ 8.35 (35,865) ​ 8.35 Balance, end of period 22,483 ​ $ 4.74 84,040 ​ $ 4.80 106,523 ​ $ 4.79 ​ Trust Company Stock Options –

EARNINGS PER SHARE

EARNINGS PER SHARE	3 Months Ended
	Jun. 30, 2022
EARNINGS PER SHARE
EARNINGS PER SHARE	4. EARNINGS PER SHARE Basic earnings per share (“EPS”) is computed by dividing net income or loss applicable to common stock by the weighted average number of common shares outstanding during the period, without considering any dilutive items. Nonvested shares of restricted stock are included in the computation of basic EPS because the holder has voting rights and shares in non-forfeitable dividends during the vesting period. Diluted EPS is computed by dividing net income applicable to common stock by the weighted average number of common shares and common stock equivalents for items that are dilutive, net of shares assumed to be repurchased using the treasury stock method at the average share price for the Company’s common stock during the period. Common stock equivalents arise from the assumed exercise of outstanding stock options.

The Company expects the fair value of these securities to recover as the securities approach their maturity dates or sooner if market yields for such securities decline. The Company does not believe that these securities are other than temporarily impaired because of their credit quality or related to any issuer or industry specific event. The Company has the ability and intent to hold the investments until the fair value recovers. Based on management’s evaluation and intent, the unrealized losses related to the investment securities in the above tables are considered temporary. The Company had no sales and realized no gains or losses on sales of investment securities for the three months ended June 30, 2022 and 2021. Investment securities available for sale with an amortized cost of $3.7 million and $1.3 million and an estimated fair value of $3.5 million and $1.2 million at June 30, 2022 and March 31, 2022, respectively, were pledged as collateral for government public funds held by the Bank. Investment securities held to maturity with an amortized cost of $13.3 million and $13.7 million and a fair value of $11.6 million and $12.6 million at June 30, 2022 and March 31, 2022, respectively, were pledged as collateral for government public funds held by the Bank.

ALLOWANCE FOR LOAN LOSSES
ALLOWANCE FOR LOAN LOSSES	​ 7. ALLOWANCE FOR LOAN LOSSES The allowance for loan losses is maintained at a level sufficient to provide for estimated probable loan losses based on evaluating known and inherent risks in the loan portfolio. The allowance is provided based upon management’s ongoing quarterly assessment of the pertinent factors underlying the quality of the loan portfolio. These factors include changes in the size and composition of the loan portfolio, delinquency levels, actual loan loss experience, current economic conditions and a detailed analysis of individual loans for which full collectability may not be assured. The detailed analysis includes techniques to estimate the fair value of loan collateral and the existence of potential alternative sources of repayment. The allowance consists of specific, general and unallocated components. The specific component relates to loans that are considered impaired. For loans that are classified as impaired, an allowance is established when the discounted cash flows or collateral value (less estimated selling costs, if applicable) of the impaired loan is lower than the carrying value of that loan. The general component covers non-impaired loans based on the Company’s risk rating system and historical loss experience adjusted for qualitative factors. The Company calculates its historical loss rates using the average of the last four quarterly 24-month periods. The Company calculates and applies its historical loss rates by individual loan types in its loan portfolio. These historical loss rates are adjusted for qualitative and environmental factors. An unallocated component is maintained to cover uncertainties that the Company believes have resulted in incurred losses that have not yet been allocated to specific elements of the general and specific components of the allowance for loan losses. Such factors include uncertainties in economic conditions, uncertainties in identifying triggering events that directly correlate to subsequent loss rates, changes in appraised value of underlying collateral, risk factors that have not yet manifested themselves in loss allocation factors and historical loss experience data that may not precisely correspond to the current loan portfolio or economic conditions. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the loan portfolio. The appropriate allowance level is estimated based upon factors and trends identified by the Company as of the date of the filing of the consolidated financial statements. When available information confirms that specific loans or portions thereof are uncollectible, identified amounts are charged against the allowance for loan losses. The existence of some or all of the following criteria will generally confirm that a loss has been incurred: the loan is significantly delinquent and the borrower has not demonstrated the ability or intent to bring the loan current; the Company has no recourse to the borrower, or if it does, the borrower has insufficient assets to pay the debt; and/or the estimated fair value of the loan collateral is significantly below the current loan balance, and there is little or no near-term prospect for improvement. Management’s evaluation of the allowance for loan losses is based on ongoing, quarterly assessments of the known and inherent risks in the loan portfolio. Loss factors are based on the Company’s historical loss experience with additional consideration and adjustments made for changes in economic conditions, changes in the amount and composition of the loan portfolio, delinquency rates, changes in collateral values, seasoning of the loan portfolio, duration of the current business cycle, a detailed analysis of impaired loans and other factors as deemed appropriate. These factors are evaluated on a quarterly basis. Loss rates used by the Company are affected as changes in these factors increase or decrease from quarter to quarter. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses and may require the Company to make additions to the allowance based on their judgment about information available to them at the time of their examinations. ​ The following tables present a reconciliation of the allowance for loan losses for the periods indicated (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended Commercial Commercial ​ ​ Multi- Real Estate ​ ​ ​ ​ ​ ​ June 30, 2022 ​ Business ​ Real Estate ​ Land ​ Family ​ Construction ​ Consumer ​ Unallocated ​ Total ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Beginning balance ​ $ 2,422 ​ $ 9,037 ​ $ 168 ​ $ 845 ​ $ 393 ​ $ 943 ​ $ 715 ​ $ 14,523 Provision for (recapture of) loan losses ​ 73 ​ ​ (495) ​ ​ (19) ​ ​ 17 ​ ​ 125 ​ ​ 257 ​ ​ 42 ​ ​ — Charge-offs ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ (6) ​ ​ — ​ ​ (6) Recoveries ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ 42 ​ ​ — ​ ​ 42 Ending balance ​ $ 2,495 ​ $ 8,542 ​ $ 149 ​ $ 862 ​ $ 518 ​ $ 1,236 ​ $ 757 ​ $ 14,559 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Beginning balance ​ $ 2,416 ​ $ 14,089 ​ $ 233 ​ $ 638 ​ $ 294 ​ $ 852 ​ $ 656 ​ $ 19,178 Provision for (recapture of) loan losses ​ (214) ​ ​ (1,147) ​ ​ 4 ​ ​ (31) ​ ​ (97) ​ ​ (152) ​ ​ 37 ​ (1,600) Charge-offs ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ (9) ​ ​ — ​ (9) Recoveries ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ 21 ​ ​ — ​ 21 Ending balance ​ $ 2,202 ​ $ 12,942 ​ $ 237 ​ $ 607 ​ $ 197 ​ $ 712 ​ $ 693 ​ $ 17,590 ​ The following tables present an analysis of loans receivable and the allowance for loan losses, based on impairment methodology, at the dates indicated (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Allowance for Loan Losses ​ Recorded Investment in Loans ​ Individually Collectively ​ ​ Individually Collectively ​ ​ ​ ​ Evaluated ​ Evaluated ​ ​ ​ ​ Evaluated ​ Evaluated ​ ​ ​ ​ ​ for ​ for ​ ​ ​ ​ for ​ for ​ ​ ​ June 30, 2022 ​ Impairment ​ Impairment ​ Total ​ Impairment ​ Impairment ​ Total ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial business ​ $ — ​ $ 2,495 ​ $ 2,495 ​ $ 95 ​ $ 226,928 ​ $ 227,023 Commercial real estate ​ — ​ 8,542 ​ ​ 8,542 ​ ​ 117 ​ ​ 578,440 ​ ​ 578,557 Land ​ — ​ 149 ​ ​ 149 ​ ​ — ​ ​ 9,863 ​ ​ 9,863 Multi-family ​ — ​ 862 ​ ​ 862 ​ ​ — ​ ​ 58,943 ​ ​ 58,943 Real estate construction ​ — ​ 518 ​ ​ 518 ​ ​ — ​ ​ 30,754 ​ ​ 30,754 Consumer ​ 7 ​ 1,229 ​ ​ 1,236 ​ ​ 486 ​ ​ 106,839 ​ ​ 107,325 Unallocated ​ — ​ 757 ​ ​ 757 ​ ​ — ​ ​ — ​ ​ — Total ​ $ 7 ​ $ 14,552 ​ $ 14,559 ​ $ 698 ​ $ 1,011,767 ​ $ 1,012,465 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2022 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial business ​ $ — ​ $ 2,422 ​ $ 2,422 ​ $ 100 ​ $ 227,991 ​ $ 228,091 Commercial real estate ​ — ​ 9,037 ​ 9,037 ​ 122 ​ ​ 582,715 ​ 582,837 Land ​ — ​ 168 ​ 168 ​ — ​ ​ 11,556 ​ 11,556 Multi-family ​ — ​ 845 ​ 845 ​ — ​ ​ 60,211 ​ 60,211 Real estate construction ​ — ​ 393 ​ 393 ​ — ​ ​ 24,160 ​ 24,160 Consumer ​ 8 ​ 935 ​ 943 ​ 495 ​ ​ 83,058 ​ 83,553 Unallocated ​ — ​ 715 ​ 715 ​ — ​ ​ — ​ — Total ​ $ 8 ​ $ 14,515 ​ $ 14,523 ​ $ 717 ​ $ 989,691 ​ $ 990,408 ​ Non-accrual loans: The following tables present an analysis of loans by aging category at the dates indicated (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total ​ ​ ​ ​ ​ ​ ​ ​ ​ 90 Days ​ ​ ​ ​ Past ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ and ​ ​ ​ ​ Due and ​ ​ ​ ​ Total ​ ​ 30-89 Days ​ Greater ​ ​ ​ ​ Non- ​ ​ ​ ​ Loans June 30, 2022 ​ Past Due ​ Past Due ​ Non-accrual ​ accrual ​ Current ​ Receivable ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial business ​ $ 1,446 ​ $ 27,254 ​ $ 113 ​ $ 28,813 ​ $ 198,210 ​ $ 227,023 Commercial real estate ​ — ​ — ​ 117 ​ ​ 117 ​ ​ 578,440 ​ ​ 578,557 Land ​ — ​ — ​ — ​ ​ — ​ ​ 9,863 ​ ​ 9,863 Multi-family ​ — ​ — ​ — ​ ​ — ​ ​ 58,943 ​ ​ 58,943 Real estate construction ​ — ​ — ​ — ​ ​ — ​ ​ 30,754 ​ ​ 30,754 Consumer ​ 14 ​ — ​ 50 ​ ​ 64 ​ ​ 107,261 ​ ​ 107,325 Total ​ $ 1,460 ​ $ 27,254 ​ $ 280 ​ $ 28,994 ​ $ 983,471 ​ $ 1,012,465 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2022 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial business ​ $ 7,753 ​ $ 21,808 ​ $ 118 ​ $ 29,679 ​ $ 198,412 ​ $ 228,091 Commercial real estate ​ — ​ — ​ 122 ​ 122 ​ 582,715 ​ 582,837 Land ​ — ​ — ​ — ​ — ​ 11,556 ​ 11,556 Multi-family ​ — ​ — ​ — ​ — ​ 60,211 ​ 60,211 Real estate construction ​ 291 ​ — ​ — ​ 291 ​ 23,869 ​ 24,160 Consumer ​ 9 ​ — ​ 51 ​ 60 ​ 83,493 ​ 83,553 Total ​ $ 8,053 ​ $ 21,808 ​ $ 291 ​ $ 30,152 ​ $ 960,256 ​ $ 990,408 ​ ​ A substantial portion of the 30-89 days past due and 90 days and greater past due loans at June 30, 2022 are comprised of government guaranteed loans. These government guaranteed loans are pass rated loans and are not considered to be nonaccrual loans given the Company expects to receive all principal and interest and not considered to be classified loans because there are no well-defined weaknesses or risk of loss. Given these government guaranteed loans are neither nonaccrual loans nor classified loans, these loans are not considered to be impaired loans based on the Company’s policy. Given these loans are not considered to be impaired loans and are fully guaranteed by the SBA or USDA, these loans are omitted from the required allowance calculation. Interest income foregone on non-accrual loans was $3,000 and $24,000 for the three months ended June 30, 2022 and the year ended March 31, 2022, respectively. ​ Credit quality indicators: Pass of the borrower and/or real estate.

For impaired loans that are not collateral dependent, impairment is measured using the present value of expected future cash flows, discounted at the loan’s original effective interest rate. When the estimated net realizable value of the impaired loan is less than the recorded investment in the loan (including accrued interest, net deferred loan fees or costs, and unamortized premium or discount), an impairment is recognized by adjusting an allocation of the allowance for loan losses. Subsequent to the initial allocation of allowance to the individual loan, the Company may conclude that it is appropriate to record a charge-off of the impaired portion of the loan. When a charge-off is recorded, the loan balance is reduced and the specific allowance is eliminated. Generally, when a collateral dependent loan is initially measured for impairment and has not had an appraisal of the collateral in the last six months, the Company obtains an updated market valuation. Subsequently, the Company generally obtains an updated market valuation of the collateral on an annual basis. The collateral valuation may occur more frequently if the Company determines that there is an indication that the market value may have declined.

TDRs are loans for which the Company, for economic or legal reasons related to the borrower’s financial condition, has granted a concession to the borrower that it would otherwise not consider. A TDR typically involves a modification of terms such as a reduction of the stated interest rate or face amount of the loan, a reduction of accrued interest, and/or an extension of the maturity date(s) at a stated interest rate lower than the current market rate for a new loan with similar risk. TDRs are considered impaired loans and as such, impairment is measured as described for impaired loans above. The following table presents TDRs by interest accrual status at the dates indicated (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2022 ​ March 31, 2022 ​ Accrual Nonaccrual Total Accrual Nonaccrual Total ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial business ​ $ — ​ $ 95 ​ $ 95 ​ $ — ​ $ 100 ​ $ 100 Commercial real estate ​ — ​ ​ 117 ​ ​ 117 ​ — ​ ​ 122 ​ ​ 122 Consumer ​ 486 ​ ​ — ​ ​ 486 ​ 495 ​ ​ — ​ ​ 495 Total ​ $ 486 ​ $ 212 ​ $ 698 ​ $ 495 ​ $ 222 ​ $ 717 ​ At June 30, 2022, the Company had no commitments to lend additional funds on TDR loans. At June 30, 2022, all of the Company’s TDRs were paying as agreed. There were no new TDRs during both the three months ended June 30, 2022 and 2021. In accordance with the Company’s policy guidelines, unsecured loans are generally charged-off when no payments have been received for three consecutive months unless an alternative action plan is in effect. Consumer installment loans delinquent six months or more that have not received at least 75% of their required monthly payment in the last 90 days are charged-off. In addition, loans discharged in bankruptcy proceedings are charged-off. Loans under bankruptcy protection with no payments received for four consecutive months are charged-off. The outstanding balance of a secured loan that is in excess of the net realizable value is generally charged-off if no payments are received for four to five consecutive months. However, charge-offs are postponed if alternative proposals to restructure, obtain additional guarantors, obtain additional assets as collateral or a potential sale of the underlying collateral would result in full repayment of the outstanding loan balance. Once any other potential sources of repayment are exhausted, the impaired portion of the loan is charged-off. Regardless of whether a loan is unsecured or collateralized, once an amount is determined to be a confirmed loan loss it is promptly charged off.

GOODWILL
GOODWILL	8. GOODWILL Goodwill and certain other intangibles generally arise from business combinations accounted for under the purchase method of accounting. Goodwill and other intangibles deemed to have indefinite lives generated from business combinations are not subject to amortization and are instead tested for impairment not less than annually. The Company has two reporting units, the Bank and the Trust Company, for purposes of evaluating goodwill for impairment. All of the Company’s goodwill has been allocated to the Bank reporting unit. The Company performed an impairment assessment as of October 31, 2021 and determined that no impairment of goodwill exists. The goodwill impairment test involves a two-step process. The first step is a comparison of the reporting unit’s fair value to its carrying value. If the reporting unit’s fair value is less than its carrying value, the Company would be required to progress to the second step. In the second step, the Company calculates the implied fair value of goodwill and compares the implied fair value of goodwill to the carrying amount of goodwill in the Company’s consolidated balance sheet. If the carrying amount of the goodwill is greater than the implied fair value of that goodwill, an impairment loss must be recognized in an amount equal to that excess. The implied fair value of goodwill is determined in the same manner as goodwill recognized in a business combination. The results of the Company’s step one test indicated that the reporting unit’s fair value was greater than its carrying value, and, therefore, a step two analysis was not required; however, no assurance can be given that the Company’s goodwill will not be written down in future periods. As a result of the effects of the COVID-19 pandemic and its impacts on the financial markets and economy, the Company completed a qualitative assessment of goodwill as of June 30, 2022, and concluded that it is more likely than not that the fair value of the Bank (the reporting unit), exceeds its carrying value at that date. If adverse economic conditions or decreases in the Company’s common stock price and market capitalization as a result of the COVID-19 pandemic were sustained in the future rather than temporary, it may significantly affect the fair value of the reporting unit and may trigger future goodwill impairment charges. Any impairment charge could have a material adverse effect on our results of operations and financial condition. ​

JUNIOR SUBORDINATED DEBENTURES
JUNIOR SUBORDINATED DEBENTURES	9. JUNIOR SUBORDINATED DEBENTURES The Company has wholly-owned subsidiary grantor trusts that were established for the purpose of issuing trust preferred securities and common securities. The trust preferred securities accrue and pay distributions periodically at specified annual rates as provided in each trust agreement. The trusts used the net proceeds from each of the offerings to purchase a like amount of junior subordinated debentures (the “Debentures”) of the Company. The Debentures are the sole assets of the trusts. The Company’s obligations under the Debentures and related documents, taken together, constitute a full and unconditional guarantee by the Company of the obligations of the trusts. The trust preferred securities are mandatorily redeemable upon maturity of the Debentures or upon earlier redemption as provided in the indentures. The Company has the right to redeem the Debentures in whole or in part on or after specific dates, at a redemption price specified in the indentures governing the Debentures plus any accrued but unpaid interest to the redemption date. The Company also has the right to defer the payment of interest on each of the Debentures for a period not to exceed 20 consecutive quarters, provided that the deferral period does not extend beyond the stated maturity. During such deferral period, distributions on the corresponding trust preferred securities will also be deferred and the Company may not pay cash dividends to the holders of shares of the Company’s common stock. The Debentures issued by the Company to the grantor trusts, totaling $26.9 million and $26.8 million at June 30, 2022 and March 31, 2022, respectively, are reported as “junior subordinated debentures” in the consolidated balance sheets. The common securities issued by the grantor trusts were purchased by the Company, and the Company’s investment in the common securities of $836,000 at both June 30, 2022 and March 31, 2022, is included in prepaid expenses and other assets in the consolidated balance sheets. The Company records interest expense on the Debentures in the consolidated statements of income.

FAIR VALUE MEASUREMENTS
FAIR VALUE MEASUREMENTS	10. FAIR VALUE MEASUREMENTS Fair value is defined under GAAP as the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. GAAP requires that valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs. GAAP also establishes a fair value hierarchy which prioritizes the valuation inputs into three broad levels. Based on the underlying inputs, each fair value measurement in its entirety is reported in one of three levels. These levels are: Quoted prices in active markets for identical assets (Level 1) Other observable inputs (Level 2) Significant unobservable inputs (Level 3) Financial instruments are presented in the tables that follow by recurring or nonrecurring measurement status. Recurring assets are initially measured at fair value and are required to be remeasured at fair value in the consolidated financial statements at each reporting date. Assets measured on a nonrecurring basis are assets that, as a result of an event or circumstance, were required to be remeasured at fair value after initial recognition in the consolidated financial statements at some time during the reporting period. The following tables present assets that are measured at estimated fair value on a recurring basis at the dates indicated (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Estimated ​ Estimated Fair Value Measurements Using June 30, 2022 Fair Value Level 1 Level 2 Level 3 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Investment securities available for sale: ​ ​ ​ ​ Municipal securities ​ $ 40,596 ​ $ — ​ $ 40,596 ​ $ — Agency securities ​ 51,214 ​ — ​ 51,214 ​ — Real estate mortgage investment conduits ​ 33,143 ​ — ​ 33,143 ​ — Residential mortgage-backed securities ​ 15,596 ​ — ​ 15,596 ​ — Other mortgage-backed securities ​ 41,148 ​ — ​ 41,148 ​ — Total assets measured at fair value on a recurring basis ​ $ 181,697 ​ $ — ​ $ 181,697 ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Estimated Estimated Fair Value Measurements Using March 31, 2022 Fair Value Level 1 Level 2 Level 3 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Investment securities available for sale: ​ ​ ​ ​ Municipal securities ​ $ 39,604 ​ $ — ​ $ 39,604 ​ $ — Agency securities ​ 40,705 ​ — ​ 40,705 ​ — Real estate mortgage investment conduits ​ 32,717 ​ — ​ 32,717 ​ — Residential mortgage-backed securities ​ 16,945 ​ — ​ 16,945 ​ — Other mortgage-backed securities ​ 35,811 ​ — ​ 35,811 ​ — Total assets measured at fair value on a recurring basis ​ $ 165,782 ​ $ — ​ $ 165,782 ​ $ — ​ There were no transfers of assets into or out of Levels 1, 2 or 3 for both the three months ended June 30, 2022 and the year ended March 31, 2022. The following methods were used to estimate the fair value of financial instruments above: Investment securities are included within Level 1 of the hierarchy when quoted prices in an active market for identical assets are available. The Company uses a third-party pricing service to assist the Company in determining the fair value of its Level 2 securities, which incorporates pricing models and/or quoted prices of investment securities with similar characteristics. Investment securities are included within Level 3 of the hierarchy when there are significant unobservable inputs. For Level 2 securities, the independent pricing service provides pricing information by utilizing evaluated pricing models supported with market data information. Standard inputs include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data from market research publications. The Company’s third-party pricing service has established processes for the Company to submit inquiries regarding the estimated fair value. In such cases, the Company’s third-party pricing service will review the inputs to the evaluation in light of any new market data presented by the Company. The Company’s third-party pricing service may then affirm the original estimated fair value or may update the evaluation on a go-forward basis. Management reviews the pricing information received from the third-party pricing service through a combination of procedures that include an evaluation of methodologies used by the pricing service, analytical reviews and performance analysis of the prices against statistics and trends. Based on this review, management determines whether the current placement of the security in the fair value hierarchy is appropriate or whether transfers may be warranted. As necessary, management compares prices received from the pricing service to discounted cash flow models or by performing independent valuations of inputs and assumptions similar to those used by the pricing service in order to help ensure prices represent a reasonable estimate of fair value. The following tables present assets that are measured at estimated fair value on a nonrecurring basis at the dates indicated (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total ​ Estimated Fair Value ​ ​ Estimated ​ Measurements Using June 30, 2022 Fair Value Level 1 Level 2 Level 3 ​ ​ ​ ​ ​ ​ ​ ​ ​ Impaired loans ​ $ 99 ​ $ — ​ $ — ​ $ 99 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2022 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Impaired loans ​ $ 228 ​ $ — ​ $ — ​ $ 228 ​ The following table presents quantitative information about Level 3 inputs for financial instruments measured at fair value on a nonrecurring basis at June 30, 2022 and March 31, 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ Valuation Significant Unobservable ​ ​ ​ Technique ​ Inputs ​ Range ​ ​ ​ ​ ​ ​ ​ Impaired loans Appraised Adjustment for market conditions N/A (1) ​ ​ Discounted cash flows ​ Discount rate ​ 5.375% - 8.000% ​ (1) There were no adjustments to appraised values of impaired loans as of June 30, 2022 and March 31, 2022. For information regarding the Company’s method for estimating the fair value of impaired loans, see Note 7 – Allowance for Loan Losses. In determining the estimated net realizable value of the underlying collateral, the Company primarily uses third-party appraisals which may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available and include consideration of variations in location, size, and income production capacity of the property. Additionally, the appraisals are periodically further adjusted by the Company in consideration of charges that may be incurred in the event of foreclosure and are based on management’s historical knowledge, changes in business factors and changes in market conditions. Impaired loans are reviewed and evaluated quarterly for additional impairment and adjusted accordingly based on the same factors identified above. Because of the high degree of judgment required in estimating the fair value of collateral underlying impaired loans and because of the relationship between fair value and general economic conditions, the Company considers the fair value of impaired loans to be highly sensitive to changes in market conditions. The following disclosure of the estimated fair value of financial instruments is made in accordance with GAAP. The Company, using available market information and appropriate valuation methodologies, has determined the estimated fair value amounts. However, considerable judgment is necessary to interpret market data in the development of the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize in the future. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. The carrying amount and estimated fair value of financial instruments is as follows at the dates indicated (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Carrying ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Estimated June 30, 2022 ​ Amount Level 1 ​ Level 2 ​ Level 3 Fair Value ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Assets: ​ ​ ​ ​ ​ Cash and cash equivalents ​ $ 141,836 ​ $ 141,836 ​ $ — ​ $ — ​ $ 141,836 Certificates of deposit held for investment ​ 249 ​ — ​ 249 ​ — ​ 249 Investment securities available for sale ​ 181,697 ​ — ​ 181,697 ​ — ​ 181,697 Investment securities held to maturity ​ 256,002 ​ — ​ 229,589 ​ — ​ 229,589 Loans receivable, net ​ 997,906 ​ — ​ — ​ 984,634 ​ 984,634 FHLB stock ​ 2,019 ​ — ​ 2,019 ​ — ​ 2,019 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Certificates of deposit ​ 110,303 ​ — ​ 107,945 ​ — ​ 107,945 Junior subordinated debentures ​ 26,854 ​ — ​ — ​ 16,533 ​ 16,533 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Carrying ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Estimated March 31, 2022 ​ Amount ​ Level 1 ​ Level 2 ​ Level 3 ​ Fair Value ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Assets: ​ ​ ​ ​ ​ Cash and cash equivalents ​ $ 241,424 ​ $ 241,424 ​ $ — ​ $ — ​ $ 241,424 Certificates of deposit held for investment ​ 249 ​ — ​ 253 ​ — ​ 253 Investment securities available for sale ​ 165,782 ​ — ​ 165,782 ​ — ​ 165,782 Investment securities held to maturity ​ 253,100 ​ — ​ 236,029 ​ — ​ 236,029 Loans receivable, net ​ 975,885 ​ — ​ — ​ 962,893 ​ 962,893 FHLB stock ​ 2,019 ​ — ​ 2,019 ​ — ​ 2,019 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ Certificates of deposit ​ 111,372 ​ — ​ 109,860 ​ — ​ 109,860 Junior subordinated debentures ​ 26,833 ​ — ​ — ​ 16,046 ​ 16,046 ​ Fair value estimates were based on existing financial instruments without attempting to estimate the value of anticipated future business.

NEW ACCOUNTING PRONOUNCEMENTS
NEW ACCOUNTING PRONOUNCEMENTS	11. NEW ACCOUNTING PRONOUNCEMENTS In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, “Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”) as amended by ASU 2018-19, ASU 2019-04, ASU 2019-05, ASU 2019-10 and ASU 2019-11. ASU 2016-13 replaces the existing incurred losses methodology for estimating allowances with a current expected credit losses methodology with respect to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held to maturity investment securities and off-balance sheet commitments. In addition, ASU 2016-13 requires credit losses relating to available for sale debt securities to be recorded through an allowance for credit losses rather than as a reduction of carrying amount. ASU 2016-13 also changes the accounting for purchased credit impaired debt securities and loans. ASU 2016-13 retains many of the current disclosure requirements in GAAP and expands certain disclosure requirements. As a “smaller reporting company” filer with the U.S. Securities and Exchange Commission, ASU 2016-13 is effective for the Company for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Upon adoption, the Company 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. In addition, the current accounting policy and procedures for other-than-temporary impairment of investment securities available for sale will be replaced with an allowance approach. The Company is reviewing the requirements of ASU 2016-13 and has begun developing and implementing processes and procedures to ensure it is fully compliant with the amendments at the adoption date. At this time, management anticipates the allowance for loan losses will change as a result of the implementation of ASU 2016-13; however, until management's evaluation is complete, the magnitude of the change will not be known. In March 2022, the FASB issued ASU 2022-02, "Financial Instruments – Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures" ("ASU 2022-02"). ASU 2022-02 eliminates the accounting guidance for TDRs in Accounting Standards Codification (“ASC”) 310-40, "Receivables - Troubled Debt Restructurings by Creditors" for entities that have adopted the CECL model introduced by ASU 2016-13. ASU 2022-02 also requires that public business entities disclose current-period gross charge-offs by year of origination for financing receivables and net investments in leases within the scope of ASC 326-20, "Financial Instruments—Credit Losses—Measured at Amortized Cost". In January 2017, the FASB issued ASU 2017-04, “Intangibles – Goodwill and Other: Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”). ASU 2017-04 simplifies the subsequent measurement of goodwill and eliminates Step 2 from the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Under ASU 2017-04, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. ASU 2017-04 is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2022. Early application of ASU 2017-04 is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of ASU 2017-04 is not expected to have a material impact on the Company's future consolidated financial statements. In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting" ("ASU 2020-04"). ASU 2020-04 applies to contracts, hedging relationships and other transactions that reference LIBOR or other rate references expected to be discontinued because of reference rate reform. ASU 2020-04 permits an entity to make necessary modifications to eligible contracts or transactions without requiring contract remeasurement or reassessment of a previous accounting determination. The Company's current interest rates on its junior subordinated debentures are based upon the three-month LIBOR plus a spread. In January 2021, ASU 2021-01 updated amendments in ASU 2020-04 to clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. ASU 2021-01 also amends the expedients and exceptions in Topic 848 to capture the incremental consequences of the scope clarification. The amendments in ASU 2021-01 have differing effective dates, beginning with interim periods including and subsequent to March 12, 2020 through December 31, 2022. The Company has not adopted ASU 2020-04 as of June 30, 2022. The adoption of ASU 2020-04 is not expected to have a material impact on the Company's future consolidated financial statements.

REVENUE FROM CONTRACTS WITH CUSTOMERS
REVENUE FROM CONTRACTS WITH CUSTOMERS	12. REVENUE FROM CONTRACTS WITH CUSTOMERS In accordance with ASC Topic 606 “Revenues from Contracts with Customers” (“ASC 606”), revenues are recognized when goods or services are transferred to the customer in exchange for the consideration the Company expects to be entitled to receive. The largest portion of the Company’s revenue is from interest income, which is not within the scope of ASC 606. All of the Company's revenue from contracts with customers within the scope of ASC 606 is recognized in non-interest income with the exception of gains on sales of REO and premises and equipment, which are included in non-interest expense. If a contract is determined to be within the scope of ASC 606, the Company recognizes revenue as it satisfies a performance obligation. Payments from customers are generally collected at the time services are rendered, monthly, or quarterly. For contracts with customers within the scope of ASC 606, revenue is either earned at a point in time or revenue is earned over time. Examples of revenue earned at a point in time are automated teller machine (“ATM”) transaction fees, wire transfer fees, overdraft fees and interchange fees. Revenue earned at a point in time is primarily based on the number and type of transactions that are generally derived from transactional information accumulated by the Company’s systems and is recognized immediately as the transactions occur or upon providing the service to complete the customer’s transaction. The Company is generally the principal in these contracts, with the exception of interchange fees, in which case the Company is acting as the agent and records revenue net of expenses paid to the principal. Examples of revenue earned over time, which generally occur on a monthly basis, are deposit account maintenance fees, investment advisory fees, merchant revenue, trust and investment management fees and safe deposit box fees. Revenue is generally derived from transactional information accumulated by the Company’s systems or those of third-parties and is recognized as the related transactions occur or services are rendered to the customer. For the three months ended June 30, 2022 and 2021, substantially all of the Company’s revenues within the scope of ASC 606 are for performance obligations satisfied at a point in time. Disaggregation of Revenue The following table includes the Company’s non-interest income, net disaggregated by type of service for the periods shown (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ 2022 2021 ​ ​ ​ ​ ​ ​ ​ ​ Asset management fees ​ $ 1,160 ​ $ 976 ​ Debit card and ATM fees ​ 903 ​ 906 ​ Deposit related fees ​ 438 ​ 400 ​ Loan related fees ​ 201 ​ 372 ​ BOLI (1) ​ 190 ​ 190 ​ FHLMC loan servicing fees (1) ​ 21 ​ 22 ​ BOLI death benefit in excess of cash surrender value (1) ​ ​ — ​ ​ 479 ​ Other, net ​ 213 ​ 243 ​ Total non-interest income, net ​ $ 3,126 ​ $ 3,588 ​ ​ (1) Not within scope of ASC 606 Revenues recognized within scope of ASC 606 Asset management fees Debit card and ATM fees Deposit related fees Loan related fees Other Contract Balances As of June 30, 2022 and 2021, the Company had no significant contract liabilities where the Company had an obligation to transfer goods or services for which the Company had already received consideration. In addition, the Company had no material unsatisfied performance obligations as of June 30, 2022 and 2021.

COMMITMENTS AND CONTINGENCIES
COMMITMENTS AND CONTINGENCIES	13. COMMITMENTS AND CONTINGENCIES Off-balance sheet arrangements Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third-party. These guarantees are primarily used to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. Collateral held varies and is required in instances where the Company deems it necessary. Significant off-balance sheet commitments at June 30, 2022 are listed below (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Contract or Notional ​ ​ Amount ​ ​ June 30, ​ 2022 Commitments to extend credit: ​ Adjustable-rate ​ $ 11,363 Fixed-rate ​ 5,575 Standby letters of credit ​ 2,203 Undisbursed loan funds and unused lines of credit ​ 150,472 Total ​ $ 169,613 ​ Other Contractual Obligations - The Bank is a public depository and, accordingly, accepts deposit and other public funds belonging to, or held for the benefit of, Washington and Oregon states, political subdivisions thereof, and municipal corporations. In accordance with applicable state law, in the event of default of a participating bank, all other participating banks in the state collectively assure that no loss of funds are suffered by any public depositor. Generally, in the event of default by a public depository, the assessment attributable to all public depositories is allocated on a pro rata basis in proportion to the maximum liability of each depository as it existed on the date of loss. The Company did not incur any losses related to public depository funds for the three months ended June 30, 2022 and 2021. The Bank has entered into employment contracts with certain key employees, which provide for contingent payments subject to future events. Litigation

LEASES
LEASES	14. LEASES The Company has a finance lease for the shell of the building constructed as the Company's operations center which expires in November 2039. The Company is also obligated under various noncancelable operating lease agreements for land, buildings and equipment that require future minimum rental payments. For operating each lease, the Company records an operating lease right-of-use asset (representing the right to use the underlying asset for the lease term) and an operating lease liability (representing the obligation to make lease payments required under the terms of the lease). Right-of-use assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The Company uses its estimated incremental borrowing rate – derived from information available at the lease commencement date – as the discount rate when determining the present value of lease payments. The Company does not have any operating leases with an initial term of 12 months or less. Certain operating leases contain various provisions for increases in rental rates, based either on changes in the published Consumer Price Index or a predetermined escalation schedule. Certain operating leases provide the Company with the option to extend the lease term one or more times following expiration of the initial term. Lease extensions are not reasonably certain and the Company generally does not include payments occurring during option periods in the calculation of its operating lease right-of-use assets and operating lease liabilities. In accordance with ASC 842, the Company records in the consolidated balance sheet operating lease right-of-use (“ROU”) assets and operating lease liabilities for leases with an initial term of more than 12 months. The table below presents the ROU assets and lease liabilities recorded in the consolidated balance sheets at the dates indicated (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ March 31, Classification in the Leases 2022 2022 consolidated balance sheets Finance lease ROU assets ​ $ 1,336 $ 1,355 Financing lease ROU assets Finance lease liability ​ $ 2,270 $ 2,283 Finance lease liability Finance lease remaining lease term ​ 17.43 years 17.68 years ​ Finance lease discount rate ​ 7.16 % 7.16 % ​ ​ ​ ​ ​ ​ ​ ​ ​ Operating lease ROU assets ​ $ 7,609 $ 7,907 Prepaid expenses and other assets Operating lease liabilities ​ $ 7,999 $ 8,306 Accrued expenses and other liabilities Operating lease weighted-average remaining lease term ​ 6.80 years 7.02 years ​ Operating lease weighted-average discount rate ​ 1.80 % 1.81 % ​ The table below presents certain information related to the lease costs for operating leases, which are recorded in occupancy and depreciation in the accompanying consolidated statements of income at the dates indicated (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended ​ Three months ended ​ Three months ended Lease Costs June 30, 2022 June 30, 2021 ​ June 30, 2020 Finance lease amortization of right-of-use asset ​ $ 19 ​ $ 19 ​ $ 19 Finance lease interest on lease liability ​ 41 ​ 42 ​ 42 Operating lease costs ​ 283 ​ 315 ​ 349 Variable lease costs ​ 52 ​ 52 ​ 52 Total lease cost (1) ​ $ 395 ​ $ 428 ​ $ 462 ​ (1) Income related to sub-lease activity is not significant and not presented herein. ​ Supplemental cash flow information - The following table reconciles the undiscounted cash flows for the periods presented related to the Company’s lease liabilities as of June 30, 2022 (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ Year Ending March 31: Operating Finance ​ ​ Leases ​ Lease Remaining of 2023 ​ $ 1,016 ​ $ 162 2024 ​ 1,370 ​ 219 2025 ​ 1,375 ​ 222 2026 ​ 1,125 ​ 226 2027 ​ 1,116 ​ 230 Thereafter ​ 2,530 ​ 2,944 Total minimum lease payments ​ 8,532 ​ 4,003 Less: amount of lease payment representing interest ​ (533) ​ (1,733) Lease liabilities ​ $ 7,999 ​ $ 2,270 ​

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, 2022 (“2022 Form 10-K”). The unaudited consolidated results of operations for the three months ended June 30, 2022 are not necessarily indicative of the results which may be expected for the entire fiscal year ending March 31, 2023. ​ 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	PRINCIPLES OF CONSOLIDATION The accompanying consolidated financial statements include the accounts of Riverview Bancorp, Inc.; its wholly-owned subsidiary, Riverview Community Bank (the “Bank”); the Bank’s wholly-owned subsidiary, Riverview Services, Inc., and the Bank’s majority-owned subsidiary, Riverview Trust Company (the “Trust Company”) (collectively referred to as the “Company”). All intercompany 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. As a result of these transactions, the Bank's ownership in the Trust Company decreased from 100% to 97.3%, resulting in a 2.7% noncontrolling interest held by the Trust Company’s President and Chief Executive Officer. The noncontrolling interest was $213,000 and $212,000 as of June 30, 2022 and March 31, 2022, respectively. Net income attributable to the noncontrolling interest was $2,000 for both the three months ended June 30, 2022 and 2021. These amounts are not presented separately in the accompanying consolidated financial statements due to their insignificance.
NEW ACCOUNTING PRONOUNCEMENTS	NEW ACCOUNTING PRONOUNCEMENTS In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, “Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”) as amended by ASU 2018-19, ASU 2019-04, ASU 2019-05, ASU 2019-10 and ASU 2019-11. ASU 2016-13 replaces the existing incurred losses methodology for estimating allowances with a current expected credit losses methodology with respect to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held to maturity investment securities and off-balance sheet commitments.

ASU 2020-04 applies to contracts, hedging relationships and other transactions that reference LIBOR or other rate references expected to be discontinued because of reference rate reform. ASU 2020-04 permits an entity to make necessary modifications to eligible contracts or transactions without requiring contract remeasurement or reassessment of a previous accounting determination. The Company's current interest rates on its junior subordinated debentures are based upon the three-month LIBOR plus a spread.

ASU 2021-01 also amends the expedients and exceptions in Topic 848 to capture the incremental consequences of the scope clarification. The amendments in ASU 2021-01 have differing effective dates, beginning with interim periods including and subsequent to March 12, 2020 through December 31, 2022. The Company has not adopted ASU 2020-04 as of June 30, 2022. The adoption of ASU 2020-04 is not expected to have a material impact on the Company's future consolidated financial statements.
