Mar. 31, 2024
. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Principles of Consolidation	Principles of Consolidation – The accompanying consolidated financial statements include the accounts of Riverview Bancorp, Inc.; its wholly-owned subsidiary, Riverview Bank (the “Bank”); the Bank’s wholly-owned subsidiaries, Riverview Services, Inc. and Riverview Trust Company (the “Trust Company”) (collectively referred to as the “Company”). As a Washington state-chartered commercial bank, the Bank’s regulators are the Washington State Department of Financial Institutions (“WDFI”) and the Federal Deposit Insurance Corporation (“FDIC”). The Board of Governors of the Federal Reserve System (“Federal Reserve”) is the primary federal regulator for Riverview Bancorp, Inc. All inter-company transactions and balances have been eliminated in consolidation. The Company has three subsidiary grantor trusts which were established in connection with the issuance of trust preferred securities (see Note 9). In accordance with accounting principles generally accepted in the United States of America (“generally accepted accounting principles” or “GAAP”), the accounts and transactions of the trusts are not included in the accompanying consolidated financial statements.
Nature of Operations	Nature of Operations – The Bank is a community-oriented financial institution which operates 17 branches in rural and suburban communities in southwest Washington State and Multnomah, Washington and Marion counties of Oregon. The Bank is engaged primarily in the business of attracting deposits from the general public and using such funds, together with other borrowings, to make various commercial business, commercial real estate, land, multi-family real estate, real estate construction and consumer loans. Additionally, the Trust Company offers trust and investment services and Riverview Services, Inc. acts as a trustee for deeds of trust on mortgage loans granted by the Bank and receives a reconveyance fee for each deed of trust.
Business segments	Business segments – The Company’s operations are managed along two operating segments, consisting of banking operations performed by the Bank and trust and investment services performed by the Trust Company. While the chief operating decision maker uses financial information related to these segments to analyze business performance and allocate resources, the trust and investment services segment does not meet the quantitative threshold under GAAP to be considered a reportable segment. As such, these operating segments are aggregated into a single reportable operating segment in the consolidated financial statements. No revenues are derived from foreign countries.
Use of Estimates in the Preparation of Consolidated Financial Statements	Use of Estimates in the Preparation of Consolidated Financial Statements – The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of certain assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of related revenue and expense during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near-term relate to the determination of the allowance for credit losses (“ACL”), the valuation of investment securities, and the valuation of goodwill for potential impairment.
Cash and Cash Equivalents	Cash and Cash Equivalents – Cash and cash equivalents include amounts on hand, due from banks and interest-earning deposits in other banks. Cash and cash equivalents have a maturity of 90 days or less at the time of purchase.
Certificates of Deposit Held for Investment	Certificates of Deposit Held for Investment – Certificates of deposit held for investment include amounts invested with financial institutions at a stated interest rate and maturity date. Early withdrawal penalties apply; however, the Company plans to hold these investments to maturity.
Investment Securities	Investment Securities – Investments in debt securities are classified as held to maturity when the Company has the ability and positive intent to hold such securities to maturity. Investments in debt securities held to maturity are carried at amortized cost. Investments in debt securities bought and held principally for the purpose of sale in the near-term are classified as trading securities. Investments in debt securities that the Company intends to hold for an indefinite period, but not necessarily to maturity, are classified as available for sale. Such debt securities may be sold to implement the Company’s asset/liability management strategies and in response to changes in interest rates and similar factors. Investments in debt securities available for sale are reported at estimated fair value. Unrealized gains and losses on investment securities available for sale, net of the related deferred tax effect, are included in total comprehensive income and are reported as a net amount in a separate component of shareholders’ equity entitled “accumulated other comprehensive income (loss).” Realized gains and losses on sales of investments in debt securities available for sale, determined using the specific identification method, are included in earnings on the trade date. Amortization of premiums and accretion of discounts are recognized in interest income over the period to contractual maturity or expected call, if sooner. The Company’s investment portfolio consists of debt securities and does not include any equity securities. The Company analyzes investments in debt securities to determine whether there have been any events or economic circumstances to indicate that a security has incurred a credit-related loss. The Company considers many factors including recent events specific to the issuer or industry, and for debt securities, external credit ratings and recent downgrades. Credit component losses are reported in non-interest income when the present value of expected future cash flows is less than the amortized cost. Noncredit component losses are recorded in other comprehensive income (loss) when the Company (1) does not intend to sell the security or (2) is not more likely than not to have to sell the security prior to the security’s anticipated recovery. If the Company is likely to sell an investment in a debt security, any noncredit component losses are recognized and are reported in non-interest income.
Loans Receivable	Loans Receivable – Loans are stated at the amount of unpaid principal, reduced by net deferred loan origination fees and an ACL. Interest on loans is accrued daily based on the principal amount outstanding. Loans are reviewed regularly and it is the Company’s general policy that a loan is past due when it is 30 days to 89 days delinquent. In general, when a loan is 90 days or more delinquent or when collection of principal or interest appears doubtful, it is placed on non-accrual status, at which time the accrual of interest ceases and a reserve for unrecoverable accrued interest is established and charged against operations. As a general practice, payments received on non-accrual loans are applied to reduce the outstanding principal balance on a cost recovery method. Also, as a general practice, a loan is not removed from non-accrual status until all delinquent principal, interest and late fees have been brought current and the borrower has demonstrated a history of performance based upon the contractual terms of the note. A history of repayment performance generally would be a minimum of six months. Loan origination and commitment fees and certain direct loan origination costs are deferred and amortized as an adjustment of the yield of the related loan.
Acquired Loans	Acquired Loans – Purchased loans, including loans acquired in business combinations, are recorded at their estimated fair value at the acquisition date. Credit discounts are included in the determination of fair value; therefore, an ACL is not recorded at the acquisition date. Acquired loans are evaluated upon acquisition and classified as either purchased credit-impaired (“PCI”) or purchased non-credit-impaired. PCI loans reflect credit deterioration since origination such that it is probable at acquisition that the Company will be unable to collect all contractually required payments. The excess of the cash flows expected to be collected over a PCI loan’s carrying value is considered to be the accretable yield and is recognized as interest income over the estimated life of the PCI loan using the effective yield method. The excess of the undiscounted contractual balances due over the cash flows expected to be collected is considered to be the nonaccretable difference. The nonaccretable difference represents the Company’s estimate of the credit losses expected to occur and would be considered in determining the estimated fair value of the loans as of the acquisition date. Subsequent to the acquisition date, any increases in expected cash flows over those expected at the purchase date in excess of fair value are adjusted through a change to the accretable yield on a prospective basis. Any subsequent decreases in expected cash flows attributable to credit deterioration are recognized by recording an ACL. The Company had no PCI loans as of March 31, 2024 and 2023. For purchased non-credit-impaired loans, the difference between the fair value and unpaid principal balance of the loan at the acquisition date is amortized or accreted to interest income over the lives of the related loans. Any subsequent deterioration in credit quality is recognized by recording an ACL.
ACL	ACL on Available for Sale Debt Securities - Each reporting period, the Company assesses each available for sale debt security that is in an unrealized loss position to determine whether the decline in fair value below the amortized cost basis results from a credit loss or other factors. The Company did not record an ACL on available for sale debt securities at March 31, 2024 or upon adoption of ASU 2016-13 on April 1, 2023. As of both dates, the Company considered the unrealized losses across the classes of major security-type to be related to fluctuations in market conditions, primarily interest rates, and not reflective of a deterioration in credit value. For available-for-sale debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If the Company intends to sell the security or it is more likely than not that the Company will be required to sell the security before recovering its cost basis, the entire impairment loss would be recognized in earnings. If the Company does not intend to sell the security and it is not more likely than not that the Company will be required to sell the security, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, Management considers the extent to which fair value is less than amortized costs, any changes to the rating of the security by a rating agency and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. Projected cash flows are discounted by the current effective interest rate. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. The remaining impairment related to all other factors, the difference between the present value of the cash flows expected to be collected and fair value, is recognized as a charge to accumulated other comprehensive income (loss) (“AOCI”). ACL on Held to Maturity Debt Securities – The Company separately evaluates its held to maturity debt securities for any credit losses based on probability of default and loss given default utilizing historical industry data based on investment category. The probability of default and loss given default are incorporated into the present value of expected cash flows and compared against amortized cost. The Company did not record an ACL on held to maturity debt securities at March 31, 2024 or upon adoption of ASU 2016-13 on April 1, 2023 as the impact was insignificant. ACL on Loans – The Company adopted the new accounting standard for the ACL (ASU 2016-13), commonly referred to as the current expected credit losses or CECL methodology, as of April 1, 2023. All disclosures as of and for the year ended March 31, 2024 are presented in accordance with ASU 2016-13. The comparative financial periods prior to the adoption of this new accounting standard are presented and disclosed under previously applicable GAAP’s incurred loss methodology, which is not directly comparable to the recently adopted CECL methodology. For further information regarding the ACL, see Note 4 to the Consolidated Financial Statements. As a result of implementing ASU 2016-13, there was a one-time adjustment to the fiscal year 2024 opening ACL balance of $42,000. The Company elected not to measure an ACL for accrued interest receivable on loans and instead elected to reverse interest income on loans or securities that are placed on nonaccrual status, which is generally when the instrument is 90 days past due, or earlier if the Company believes the collection of interest is doubtful. The Company has concluded that this policy results in the timely reversal of uncollectible interest. The ACL for loans is an estimate of the expected credit losses on financial assets measured at amortized cost. The ACL for loans is evaluated based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. Historical loss experience is generally the starting point for estimating expected credit losses. The Company then considers whether the historical loss experience should be adjusted for asset-specific risk characteristics or current conditions at the reporting date that did not exist over the period that historical experience was based for each loan type. Finally, the Company consider forecasts about future economic conditions or changes in collateral values that are reasonable and supportable. The Company estimates the expected credit losses over the loans’ contractual terms, adjusted for expected prepayments. The ACL for loans is calculated for loan segments utilizing loan level information and relevant information from internal and external sources related to past events and current conditions. The methodology for estimating the amount of expected credit losses has two basic components: a general component for estimated expected credit losses for pools of loans that share similar risk characteristics and an individual component involving individual loans that do not share risk characteristics with other loans and the measurement of expected credit losses for such individual loans. The Company's ACL model methodology is to build a reserve rate using historical life of loan default rates combined with assessments of current loan portfolio information and current and forecasted economic environment and business cycle information. The model uses statistical analysis to determine the life of loan default rates for the quantitative component and analyzes qualitative factors (Q-Factors) that assess the current loan portfolio conditions and forecasted economic environment and collateral values. For loans that are individually evaluated, 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. When available information confirms that specific loans or portions thereof are uncollectible, identified amounts are charged against the ACL. 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 ACL for loans is based on ongoing, quarterly assessments of the known and inherent risks in the loan portfolio. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Company’s ACL for loans and may require the Company to make additions to the ACL for loans based on their judgment about information available to them at the time of their examinations.
ACL for Unfunded Loan Commitments	ACL for Unfunded Loan Commitments – The allowance for unfunded loan commitments is maintained at a level believed by management to be sufficient to absorb estimated expected losses related to these unfunded credit facilities. The determination of the adequacy of the allowance is based on periodic evaluations of the unfunded credit facilities including an assessment of the probability of commitment usage, credit risk factors for loans outstanding to these same customers, and the terms and expiration dates of the unfunded credit facilities. Changes in the allowance for credit losses – unfunded loan commitments are recognized as provision for (or recapture of) credit loss expense and added to the allowance for credit losses – unfunded loan commitments, which is included in accrued expenses and other liabilities in the consolidated balance sheets.
REO	REO – REO consists of properties acquired through foreclosure and is initially recorded at the estimated fair value of the properties, less estimated costs of disposal. At the time of foreclosure, specific charge-offs are taken against the ACL based upon a detailed analysis of the fair value of collateral on the underlying loans on which the Company is in the process of foreclosing. Subsequently, the Company performs an evaluation of the properties and records a valuation allowance with an offsetting charge to REO expenses for any declines in value. Management considers third-party appraisals, as well as independent fair market value assessments from realtors or persons involved in selling real estate, in determining the estimated fair value of particular properties. In addition, as certain of these third-party appraisals and independent fair market value assessments are only updated periodically, changes in the values of specific properties may have occurred subsequent to the most recent appraisals. The amounts the Company will ultimately recover and record in the accompanying consolidated financial statements from the disposition of REO may differ from the amounts used in arriving at the net carrying value of these assets because of future market factors beyond the Company’s control or because of changes in the Company’s strategy for the sale of the property. Costs relating to development and improvement of the properties or assets are capitalized, while costs relating to holding the properties or assets are expensed. The Company held no REO at March 31, 2024 and 2023. At March 31, 2024, there were no mortgage loans secured by residential real estate for which formal foreclosure proceedings were in process.
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock – The Bank, as a member of the Federal Home Loan Bank of Des Moines (“FHLB”), is required to maintain a minimum investment in capital stock of the FHLB based on specific percentages of its outstanding FHLB advances. The Company’s investment in FHLB stock is carried at cost, which approximates fair value. The Company views its investment in FHLB stock as a long-term investment. Accordingly, when evaluating FHLB stock for impairment, the value is determined based on the ultimate redemption of the par value rather than recognizing temporary declines in value. The determination of whether a decline affects the ultimate redemption value is influenced by criteria such as: (1) the significance of any decline in net assets of the FHLB as compared to the capital stock amount of the FHLB and the length of time this situation has persisted, (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB, (3) the impact of legislative and regulatory changes on institutions and, accordingly, the customer base of the FHLB, and (4) the liquidity position of the FHLB. The Company has determined there is no impairment on the FHLB stock investment at March 31, 2024 and 2023.
Premises and Equipment	Premises and Equipment – Premises and equipment are stated at cost less accumulated depreciation and amortization. Leasehold improvements are amortized over the estimated term of the related lease or the estimated useful life of the improvements, whichever is less. Depreciation and amortization are generally computed on the straight-line method over the following estimated useful lives: buildings and improvements – up to 45 years; furniture and equipment – 3 to 20 years; and leasehold improvements – 15 to 25 years, or estimated lease term if shorter. Gains or losses on dispositions are reflected in earnings. The cost of maintenance and repairs is charged to expense as incurred. Assets are reviewed for impairment when events indicate their carrying value may not be recoverable. If management determines impairment exists the asset is reduced by an offsetting charge to expense. The assets held under the finance lease are amortized on a straight-line basis over the lease term and the amortization is included in depreciation and amortization expense.
Mortgage Servicing Rights ("MSRs")	Mortgage Servicing Rights (“MSRs”) – The Company services certain loans that it has originated and sold to the Federal Home Loan Mortgage Corporation (“FHLMC”). Loan servicing includes collecting payments; remitting funds to investors, insurance companies and tax authorities; collecting delinquent payments; and foreclosing on properties when necessary. Fees earned for servicing loans for the FHLMC are reported as income when the related mortgage loan payments are collected. Loan servicing costs are charged to expense as incurred. In addition, the Company has recorded MSRs, which represent the rights to service loans. The Company records its originated MSRs at fair value in accordance with GAAP, which requires the Company to allocate the total cost of all mortgage loans sold between loans sold with MSRs retained and loans with MSRs released, based on their relative fair values if it is practicable to estimate those fair values. The Company stratifies its MSRs based on the predominant characteristics of the underlying financial assets including the coupon interest rate and the contractual maturity of the mortgage. The Company is amortizing the MSRs in proportion to and over the period of estimated net servicing income. MSRs were fully amortized at March 31, 2023.
Business Combinations, CDI and Goodwill	Business Combinations, CDI and Goodwill – GAAP requires the total purchase price in a business combination to be allocated to the estimated fair values of assets acquired and liabilities assumed, including certain intangible assets. Subsequent adjustments to the initial allocation of the purchase price may be made related to fair value estimates for which all relevant information has not been obtained, known, or discovered relating to the acquired entity during the allocation period (which is the period of time required to identify and measure the estimated fair values of the assets acquired and liabilities assumed in a business combination). The allocation period is generally limited to one year following consummation of a business combination. CDI represents the value assigned to demand, interest checking, money market and savings accounts acquired as part of a business combination. CDI represents the future economic benefit of the potential cost savings from acquiring core deposits as part of a business combination compared to the cost of alternative funding sources. CDI is amortized to non-interest expense using an accelerated method based on an estimated runoff of related deposits over a period of ten years. CDI is evaluated for impairment and recoverability whenever events or changes in circumstances indicate that its carrying amount may not be recoverable, with any changes in estimated useful life accounted for prospectively over the revised remaining life. At both March 31, 2024 and 2023, gross CDI was $1.4 million. At March 31, 2024 and 2023, accumulated amortization was $1.1 million and $984,000, respectively. The amortization expense for CDI in future years is estimated to be $100,000, $93,000, and $78,000, for the years ending March 31, 2025, 2026, and 2027, respectively. Goodwill and certain other intangibles generally arise from business combinations. Goodwill and other intangibles generated from business combinations that are deemed to have indefinite lives are not subject to amortization and are instead tested for impairment not less than annually. The Company performs an annual review in the third quarter of each year, or more frequently if indicators of potential impairment exist, to determine if the recorded goodwill is impaired (see Note 6).
BOLI	BOLI – BOLI policies are recorded at their cash surrender value less applicable surrender charges. Income from BOLI is recognized when earned.
Advertising and Marketing	Advertising and Marketing – Costs incurred for advertising, merchandising, market research, community investment and business development are classified as advertising and marketing expense and are expensed as incurred.
Income Taxes	Income Taxes – Income taxes are accounted for using the asset and liability method. Under this method, a deferred tax asset or liability is determined based on the enacted tax rates which will be in effect when the differences between the financial statement carrying amounts and tax basis of existing assets and liabilities are expected to be reported in the Company’s income tax returns. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established to reduce the net carrying amount of deferred tax assets if it is determined to be more likely than not that all or some portion of the potential deferred tax asset will not be realized. The Company files a consolidated federal income tax return. The Bank provides for income taxes separately and remits to the Company amounts currently due.
Transfer of financial assets	Transfers of financial assets – Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Trust Assets	Trust Assets – Assets held by the Trust Company in a fiduciary or agency capacity for trust customers are not included in the consolidated financial statements because such items are not assets of the Company. Assets totaling $961.8 million were held in trust as of March 31, 2024 compared to $890.6 million as of March 31, 2023.
Earnings Per Share	Earnings Per Share – GAAP requires all companies whose capital structure includes dilutive potential common shares to make a dual presentation of basic and diluted earnings per share for all periods presented. The Company’s basic earnings per share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding for the period, without consideration of any dilutive items. Nonvested shares of restricted stock are included in the computation of basic earnings per share because the holder has voting rights and shares in non-forfeitable dividends during the vesting period. The Company’s diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised and has been computed after considering to the weighted average diluted effect of the Company’s stock options.
Stock-Based Compensation	Stock-Based Compensation – The Company measures compensation cost for all stock-based awards based on the grant-date fair value of the awards and recognizes compensation cost over the service period of stock-based awards. The fair value of stock options is determined using the Black-Scholes valuation model. The fair value of restricted stock is determined based on the grant date fair value of the Company’s common stock.
Accounting Pronouncements Recently Issued or Adopted	Accounting Pronouncements Recently Issued or Adopted – 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 ASU 2016-13, 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 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 year ended March 31, 2024. The Company had $13,000 in write offs and $26,000 in recoveries from other installment loans for the year ended March 31, 2024.
Reclassifications	Reclassifications – 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.

. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation – The accompanying consolidated financial statements include the accounts of Riverview Bancorp, Inc.; its wholly-owned subsidiary, Riverview Bank (the “Bank”); the Bank’s wholly-owned subsidiaries, Riverview Services, Inc. and Riverview Trust Company (the “Trust Company”) (collectively referred to as the “Company”). As a Washington state-chartered commercial bank, the Bank’s regulators are the Washington State Department of Financial Institutions (“WDFI”) and the Federal Deposit Insurance Corporation (“FDIC”). The Board of Governors of the Federal Reserve System (“Federal Reserve”) is the primary federal regulator for Riverview Bancorp, Inc. All inter-company transactions and balances have been eliminated in consolidation.

The Company has three subsidiary grantor trusts which were established in connection with the issuance of trust preferred securities (see Note 9). In accordance with accounting principles generally accepted in the United States of America (“generally accepted accounting principles” or “GAAP”), the accounts and transactions of the trusts are not included in the accompanying consolidated financial statements.

Nature of Operations

Nature of Operations – The Bank is a community-oriented financial institution which operates 17 branches in rural and suburban communities in southwest Washington State and Multnomah, Washington and Marion counties of Oregon. The Bank is engaged primarily in the business of attracting deposits from the general public and using such funds, together with other borrowings, to make various commercial business, commercial real estate, land, multi-family real estate, real estate construction and consumer loans. Additionally, the Trust Company offers trust and investment services and Riverview Services, Inc. acts as a trustee for deeds of trust on mortgage loans granted by the Bank and receives a reconveyance fee for each deed of trust.

Business segments

Business segments – The Company’s operations are managed along two operating segments, consisting of banking operations performed by the Bank and trust and investment services performed by the Trust Company. While the chief operating decision maker uses financial information related to these segments to analyze business performance and allocate resources, the trust and investment services segment does not meet the quantitative threshold under GAAP to be considered a reportable segment. As such, these operating segments are aggregated into a single reportable operating segment in the consolidated financial statements. No revenues are derived from foreign countries.

Use of Estimates in the Preparation of Consolidated Financial Statements

Use of Estimates in the Preparation of Consolidated Financial Statements – The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of certain assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of related revenue and expense during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near-term relate to the determination of the allowance for credit losses (“ACL”), the valuation of investment securities, and the valuation of goodwill for potential impairment.

Cash and Cash Equivalents

Cash and Cash Equivalents – Cash and cash equivalents include amounts on hand, due from banks and interest-earning deposits in other banks. Cash and cash equivalents have a maturity of 90 days or less at the time of purchase.

Certificates of Deposit Held for Investment

Certificates of Deposit Held for Investment – Certificates of deposit held for investment include amounts invested with financial institutions at a stated interest rate and maturity date. Early withdrawal penalties apply; however, the Company plans to hold these investments to maturity.

Investment Securities

Investment Securities – Investments in debt securities are classified as held to maturity when the Company has the ability and positive intent to hold such securities to maturity. Investments in debt securities held to maturity are carried at amortized cost. Investments in debt securities bought and held principally for the purpose of sale in the near-term are classified as trading securities. Investments in debt securities that the Company intends to hold for an indefinite period, but not necessarily to maturity, are classified as available for sale. Such debt securities may be sold to implement the Company’s asset/liability management strategies and in response to changes in interest rates and similar factors. Investments in debt securities available for sale are reported at estimated fair value. Unrealized gains and losses on investment securities available for sale, net of the related deferred tax effect, are included in total comprehensive income and are reported as a net amount in a separate component of shareholders’ equity entitled “accumulated other comprehensive income (loss).” Realized gains and losses on sales of investments in debt securities available for sale, determined using the specific identification method, are included in earnings on the trade date. Amortization of premiums and accretion of discounts are recognized in interest income over the period to contractual maturity or expected call, if sooner. The Company’s investment portfolio consists of debt securities and does not include any equity securities.

The Company analyzes investments in debt securities to determine whether there have been any events or economic circumstances to indicate that a security has incurred a credit-related loss. The Company considers many factors including recent events specific to the issuer or industry, and for debt securities, external credit ratings and recent downgrades. Credit component losses are reported in non-interest income when the present value of expected future cash flows is less than the amortized cost. Noncredit component losses are recorded in other comprehensive income (loss) when the Company (1) does not intend to sell the security or (2) is not more likely than not to have to sell the security prior to the security’s anticipated recovery. If the Company is likely to sell an investment in a debt security, any noncredit component losses are recognized and are reported in non-interest income.

Loans Receivable

Loans Receivable – Loans are stated at the amount of unpaid principal, reduced by net deferred loan origination fees and an ACL. Interest on loans is accrued daily based on the principal amount outstanding.

Loans are reviewed regularly and it is the Company’s general policy that a loan is past due when it is 30 days to 89 days delinquent. In general, when a loan is 90 days or more delinquent or when collection of principal or interest appears doubtful, it is placed on non-accrual status, at which time the accrual of interest ceases and a reserve for unrecoverable accrued interest is established and charged against operations. As a general practice, payments received on non-accrual loans are applied to reduce the outstanding principal balance on a cost recovery method. Also, as a general practice, a loan is not removed from non-accrual status until all delinquent principal, interest and late fees have been brought current and the borrower has demonstrated a history of performance based upon the contractual terms of the note. A history of repayment performance generally would be a minimum of six months.

Loan origination and commitment fees and certain direct loan origination costs are deferred and amortized as an adjustment of the yield of the related loan.

Acquired Loans

Acquired Loans – Purchased loans, including loans acquired in business combinations, are recorded at their estimated fair value at the acquisition date. Credit discounts are included in the determination of fair value; therefore, an ACL is not recorded at the acquisition date. Acquired loans are evaluated upon acquisition and classified as either purchased credit-impaired (“PCI”) or purchased non-credit-impaired. PCI loans reflect credit deterioration since origination such that it is probable at acquisition that the Company will be unable to collect all contractually required payments. The excess of the cash flows expected to be collected over a PCI loan’s carrying value is considered to be the accretable yield and is recognized as interest income over the estimated life of the PCI loan using the effective yield method. The excess of the undiscounted contractual balances due over the cash flows expected to be collected is considered to be the nonaccretable difference. The nonaccretable difference represents the Company’s estimate of the credit losses expected to occur and would be considered in determining the estimated fair value of the loans as of the acquisition date. Subsequent to the acquisition date, any increases in expected cash flows over those expected at the purchase date in excess of fair value are adjusted through a change to the accretable yield on a prospective basis. Any subsequent decreases in expected cash flows attributable to credit deterioration are recognized by recording an ACL. The Company had no PCI loans as of March 31, 2024 and 2023.

For purchased non-credit-impaired loans, the difference between the fair value and unpaid principal balance of the loan at the acquisition date is amortized or accreted to interest income over the lives of the related loans. Any subsequent deterioration in credit quality is recognized by recording an ACL.

ACL

ACL on Available for Sale Debt Securities - Each reporting period, the Company assesses each available for sale debt security that is in an unrealized loss position to determine whether the decline in fair value below the amortized cost basis results from a credit loss or other factors. The Company did not record an ACL on available for sale debt securities at March 31, 2024 or upon adoption of ASU 2016-13 on April 1, 2023. As of both dates, the Company considered the unrealized losses across the classes of major security-type to be related to fluctuations in market conditions, primarily interest rates, and not reflective of a deterioration in credit value.

For available-for-sale debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If the Company intends to sell the security or it is more likely than not that the Company will be required to sell the security before recovering its cost basis, the entire impairment loss would be recognized in earnings. If the Company does not intend to sell the security and it is not more likely than not that the Company will be required to sell the security, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, Management considers the extent to which fair value is less than amortized costs, any changes to the rating of the security by a rating agency and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. Projected cash flows are discounted by the current effective interest rate. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. The remaining impairment related to all other factors, the difference between the present value of the cash flows expected to be collected and fair value, is recognized as a charge to accumulated other comprehensive income (loss) (“AOCI”).

ACL on Held to Maturity Debt Securities – The Company separately evaluates its held to maturity debt securities for any credit losses based on probability of default and loss given default utilizing historical industry data based on investment category. The probability of default and loss given default are incorporated into the present value of expected cash flows and compared against amortized cost. The Company did not record an ACL on held to maturity debt securities at March 31, 2024 or upon adoption of ASU 2016-13 on April 1, 2023 as the impact was insignificant.

ACL on Loans – The Company adopted the new accounting standard for the ACL (ASU 2016-13), commonly referred to as the current expected credit losses or CECL methodology, as of April 1, 2023. All disclosures as of and for the year ended March 31, 2024 are presented in accordance with ASU 2016-13. The comparative financial periods prior to the adoption of this new accounting standard are presented and disclosed under previously applicable GAAP’s incurred loss methodology, which is not directly comparable to the recently adopted CECL methodology. For further information regarding the ACL, see Note 4 to the Consolidated Financial Statements. As a result of implementing ASU 2016-13, there was a one-time adjustment to the fiscal year 2024 opening ACL balance of $42,000. The Company elected not to measure an ACL for accrued interest receivable on loans and instead elected to reverse interest income on loans or securities that are placed on nonaccrual status, which is generally when the instrument is 90 days past due, or earlier if the Company believes the collection of interest is doubtful. The Company has concluded that this policy results in the timely reversal of uncollectible interest.

The ACL for loans is an estimate of the expected credit losses on financial assets measured at amortized cost. The ACL for loans is evaluated based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. Historical loss experience is generally the starting point for estimating expected credit losses. The Company then considers whether the historical loss experience should be adjusted for asset-specific risk characteristics or current conditions at the reporting date that did not exist over the period that historical experience was based for each loan type. Finally, the Company consider forecasts about future economic conditions or changes in collateral values that are reasonable and supportable. The Company estimates the expected credit losses over the loans’ contractual terms, adjusted for expected prepayments. The ACL for loans is calculated for loan segments utilizing loan level information and relevant information from internal and external sources related to past events and current conditions.

The methodology for estimating the amount of expected credit losses has two basic components: a general component for estimated expected credit losses for pools of loans that share similar risk characteristics and an individual component involving individual loans that do not share risk characteristics with other loans and the measurement of expected credit losses for such individual loans. The Company's ACL model methodology is to build a reserve rate using historical life of loan default rates combined with assessments of current loan portfolio information and current and forecasted economic environment and business cycle information. The model uses statistical analysis to determine the life of loan default rates for the quantitative component and analyzes qualitative factors (Q-Factors) that assess the current loan portfolio conditions and forecasted economic environment and collateral values. For loans that are individually evaluated, 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.

When available information confirms that specific loans or portions thereof are uncollectible, identified amounts are charged against the ACL. 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 ACL for loans is based on ongoing, quarterly assessments of the known and inherent risks in the loan portfolio. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Company’s ACL for loans and may require the Company to make additions to the ACL for loans based on their judgment about information available to them at the time of their examinations.

ACL for Unfunded Loan Commitments

ACL for Unfunded Loan Commitments – The allowance for unfunded loan commitments is maintained at a level believed by management to be sufficient to absorb estimated expected losses related to these unfunded credit facilities. The determination of the adequacy of the allowance is based on periodic evaluations of the unfunded credit facilities including an assessment of the probability of commitment usage, credit risk factors for loans outstanding to these same customers, and the terms and expiration dates of the unfunded credit facilities. Changes in the allowance for credit losses – unfunded loan commitments are recognized as provision for (or recapture of) credit loss expense and added to the allowance for credit losses – unfunded loan commitments, which is included in accrued expenses and other liabilities in the consolidated balance sheets.

REO

REO – REO consists of properties acquired through foreclosure and is initially recorded at the estimated fair value of the properties, less estimated costs of disposal. At the time of foreclosure, specific charge-offs are taken against the ACL based upon a detailed analysis of the fair value of collateral on the underlying loans on which the Company is in the process of foreclosing. Subsequently, the Company performs an evaluation of the properties and records a valuation allowance with an offsetting charge to REO expenses for any declines in value. Management considers third-party appraisals, as well as independent fair market value assessments from realtors or persons involved in selling real estate, in determining the estimated fair value of particular properties. In addition, as certain of these third-party appraisals and independent fair market value assessments are only updated periodically, changes in the values of specific properties may have occurred subsequent to the most recent appraisals. The amounts the Company will ultimately recover and record in the accompanying consolidated financial statements from the disposition of REO may differ from the amounts used in arriving at the net carrying value of these assets because of future market factors beyond the Company’s control or because of changes in the Company’s strategy for the sale of the property. Costs relating to development and improvement of the properties or assets are capitalized, while costs relating to holding the properties or assets are expensed. The Company held no REO at March 31, 2024 and 2023. At March 31, 2024, there were no mortgage loans secured by residential real estate for which formal foreclosure proceedings were in process.

Federal Home Loan Bank Stock

Federal Home Loan Bank Stock – The Bank, as a member of the Federal Home Loan Bank of Des Moines (“FHLB”), is required to maintain a minimum investment in capital stock of the FHLB based on specific percentages of its outstanding FHLB advances. The Company’s investment in FHLB stock is carried at cost, which approximates fair value. The Company views its investment in FHLB stock as a long-term investment. Accordingly, when evaluating FHLB stock for impairment, the value is determined based on the ultimate redemption of the par value rather than recognizing temporary declines in value. The determination of whether a decline affects the ultimate redemption value is influenced by criteria such as: (1) the significance of any decline in net assets of the FHLB as compared to the capital stock amount of the FHLB and the length of time this situation has persisted, (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB, (3) the impact of legislative and regulatory changes on institutions and, accordingly, the customer base of the FHLB, and (4) the liquidity position of the FHLB. The Company has determined there is no impairment on the FHLB stock investment at March 31, 2024 and 2023.

Premises and Equipment

Premises and Equipment – Premises and equipment are stated at cost less accumulated depreciation and amortization. Leasehold improvements are amortized over the estimated term of the related lease or the estimated useful life of the improvements, whichever is less. Depreciation and amortization are generally computed on the straight-line method over the following estimated useful lives: buildings and improvements – up to 45 years; furniture and equipment – 3 to 20 years; and leasehold improvements – 15 to 25 years, or estimated lease term if shorter. Gains or losses on dispositions are reflected in earnings. The cost of maintenance and repairs is charged to expense as incurred. Assets are reviewed for impairment when events indicate their carrying value may not be recoverable. If management determines impairment exists the asset is reduced by an offsetting charge to expense.

The assets held under the finance lease are amortized on a straight-line basis over the lease term and the amortization is included in depreciation and amortization expense.

Mortgage Servicing Rights ("MSRs")

Mortgage Servicing Rights (“MSRs”) – The Company services certain loans that it has originated and sold to the Federal Home Loan Mortgage Corporation (“FHLMC”). Loan servicing includes collecting payments; remitting funds to investors, insurance companies and tax authorities; collecting delinquent payments; and foreclosing on properties when necessary. Fees earned for servicing loans for the FHLMC are reported as income when the related mortgage loan payments are collected. Loan servicing costs are charged to expense as incurred. In addition, the Company has recorded MSRs, which represent the rights to service loans.

The Company records its originated MSRs at fair value in accordance with GAAP, which requires the Company to allocate the total cost of all mortgage loans sold between loans sold with MSRs retained and loans with MSRs released, based on their relative fair values if it is practicable to estimate those fair values. The Company stratifies its MSRs based on the predominant characteristics of the underlying financial assets including the coupon interest rate and the contractual maturity of the mortgage. The Company is amortizing the MSRs in proportion to and over the period of estimated net servicing income. MSRs were fully amortized at March 31, 2023.

Business Combinations, CDI and Goodwill

Business Combinations, CDI and Goodwill – GAAP requires the total purchase price in a business combination to be allocated to the estimated fair values of assets acquired and liabilities assumed, including certain intangible assets. Subsequent adjustments to the initial allocation of the purchase price may be made related to fair value estimates for which all relevant information has not been obtained, known, or discovered relating to the acquired entity during the allocation period (which is the period of time required to identify and measure the estimated fair values of the assets acquired and liabilities assumed in a business combination). The allocation period is generally limited to one year following consummation of a business combination.

CDI represents the value assigned to demand, interest checking, money market and savings accounts acquired as part of a business combination. CDI represents the future economic benefit of the potential cost savings from acquiring core deposits as part of a business combination compared to the cost of alternative funding sources. CDI is amortized to non-interest expense using an accelerated method based on an estimated runoff of related deposits over a period of ten years. CDI is evaluated for impairment and recoverability whenever events or changes in circumstances indicate that its carrying amount may not be recoverable, with any changes in estimated useful life accounted for prospectively over the revised remaining life. At both March 31, 2024 and 2023, gross CDI was $1.4 million. At March 31, 2024 and 2023, accumulated amortization was $1.1 million and $984,000, respectively. The amortization expense for CDI in future years is estimated to be $100,000, $93,000, and $78,000, for the years ending March 31, 2025, 2026, and 2027, respectively.

Goodwill and certain other intangibles generally arise from business combinations. Goodwill and other intangibles generated from business combinations that are deemed to have indefinite lives are not subject to amortization and are instead tested for impairment not less than annually. The Company performs an annual review in the third quarter of each year, or more frequently if indicators of potential impairment exist, to determine if the recorded goodwill is impaired (see Note 6).

BOLI

BOLI – BOLI policies are recorded at their cash surrender value less applicable surrender charges. Income from BOLI is recognized when earned.

Advertising and Marketing

Advertising and Marketing – Costs incurred for advertising, merchandising, market research, community investment and business development are classified as advertising and marketing expense and are expensed as incurred.

Income Taxes

Income Taxes – Income taxes are accounted for using the asset and liability method. Under this method, a deferred tax asset or liability is determined based on the enacted tax rates which will be in effect when the differences between the financial statement carrying amounts and tax basis of existing assets and liabilities are expected to be reported in the Company’s income tax returns. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date.

Valuation allowances are established to reduce the net carrying amount of deferred tax assets if it is determined to be more likely than not that all or some portion of the potential deferred tax asset will not be realized. The Company files a consolidated federal income tax return. The Bank provides for income taxes separately and remits to the Company amounts currently due.

Transfer of financial assets

Transfers of financial assets – Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.

Trust Assets

Trust Assets – Assets held by the Trust Company in a fiduciary or agency capacity for trust customers are not included in the consolidated financial statements because such items are not assets of the Company. Assets totaling $961.8 million were held in trust as of March 31, 2024 compared to $890.6 million as of March 31, 2023.

Earnings Per Share

Earnings Per Share – GAAP requires all companies whose capital structure includes dilutive potential common shares to make a dual presentation of basic and diluted earnings per share for all periods presented. The Company’s basic earnings per share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding for the period, without consideration of any dilutive items. Nonvested shares of restricted stock are included in the computation of basic earnings per share because the holder has voting rights and shares in non-forfeitable dividends during the vesting period. The Company’s diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised and has been computed after considering to the weighted average diluted effect of the Company’s stock options.

Stock-Based Compensation

Stock-Based Compensation – The Company measures compensation cost for all stock-based awards based on the grant-date fair value of the awards and recognizes compensation cost over the service period of stock-based awards. The fair value of stock options is determined using the Black-Scholes valuation model. The fair value of restricted stock is determined based on the grant date fair value of the Company’s common stock.

Accounting Pronouncements Recently Issued or Adopted

Accounting Pronouncements Recently Issued or Adopted –

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

ASU 2016-13, 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 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 year ended March 31, 2024. The Company had $13,000 in write offs and $26,000 in recoveries from other installment loans for the year ended March 31, 2024.

Reclassifications

Reclassifications – 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.
