Nature of Operations and Summary of Significant Accounting Policies
Nature of Operations and Summary of Significant Accounting Policies	Note 1: Nature of Operations Van Wert Federal Savings Bank (Bank) is a federally chartered mutual thrift engaged primarily in the business of making residential mortgage loans and accepting deposits. Its operations are conducted through its office located in Van Wert, Ohio. The Bank faces competition from other financial institutions and is subject to the regulation of certain federal and state agencies and undergoes periodic examinations by those regulatory authorities. On March 3, 2022, the Board of Directors of the Bank adopted a plan of conversion (Plan) under which the Bank proposed to convert into a stock savings bank structure with the establishment of a stock holding company (VWF Bancorp, Inc.), as parent of the Bank. The conversion was completed effective July 13, 2022. See Note 15 for details of the conversion. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, valuation of deferred tax assets and fair values of financial instruments. Change in Accounting Principle In March 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2017-08 Premium Amortization on Purchased Callable Debt Securities . The Bank adopted ASU 2017-08 effective July 1, 2020, as required. As provided for in the ASU, a cumulative effect adjustment, representing a charge of $64,489, was recorded to retained earnings upon adoption, which equaled the difference at that date between use of the shorter amortization period to the call date for securities affected by the change. Cash Equivalents The Bank considers all liquid investments with original maturities of three months or less to be cash equivalents. At June 30, 2022 none of the Bank’s cash accounts at nonfederal government or nongovernmental agencies exceeded FDIC insurance limits. Interest-bearing Time Deposits in Banks Interest-bearing time deposits have original maturities greater than one year and are carried at cost. Debt Securities Debt securities held by the Bank generally are classified and recorded in the financial statements as follows: Classified as ​ Description ​ Recorded at Held to maturity (HTM) ​ Certain debt securities that management has the positive intent and ability to hold to maturity ​ Amortized cost ​ ​ ​ ​ ​ ​ ​ Trading ​ Securities that are bought and held principally for the purpose of selling in the near term and, therefore, held for only a short period of time ​ Fair value, with changes in fair value included in earnings ​ ​ ​ ​ ​ ​ ​ Available for sale (AFS) ​ Securities not classified as HTM or trading ​ Fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income ​ ​ Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities, identified as the call date as to premiums and maturity date as to discounts. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. When the fair value of securities is below amortized cost, the Bank’s accounting treatment for an other-than-temporary impairment (OTTI) is as follows: ​ ​ Accounting Treatment for OTTI ​ ​ Components ​ Circumstances of Impairment Credit Remaining ​ Considerations ​ Component ​ Portion ​ Not intended for sale and more likely than not that the Bank will not have to sell before recovery of cost basis ​ Recognized in earnings ​ Recognized in other comprehensive income ​ ​ ​ ​ ​ ​ ​ Intended for sale or more likely than not that the Bank will be required to sell before recovery of cost basis ​ Recognized in earnings ​ ​ For held-to-maturity debt securities, the amount of OTTI recorded in other comprehensive income for the noncredit portion of a previous OTTI is amortized prospectively over the remaining life of the security on the basis of the timing of future estimated cash flows of the security. When a credit loss component is separately recognized in earnings, the amount is identified as the total of principal cash flows not expected to be received over the remaining term of the security, as projected based on cash flow projections. The Bank recognized no other-than-temporary impairments on debt securities in 2022 or 2021. Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding principal balances adjusted for unearned income, charge-offs, the allowance for loan losses and any unamortized deferred fees or costs on originated loans and unamortized premiums or discounts on purchased loans. For loans amortized at cost, interest income is accrued based on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, as well as premiums and discounts, are deferred and amortized as a level yield adjustment over the respective term of the loan. For all loan portfolio segments except residential and consumer loans, the Bank promptly charges-off loans, or portions thereof, when available information confirms that specific loans are uncollectible based on information that includes, but is not limited to, (1) the deteriorating financial condition of the borrower, (2) declining collateral values, and/or (3) legal action, including bankruptcy, that impairs the borrower’s ability to adequately meet its obligations. For impaired loans that are considered to be solely collateral dependent, a partial charge-off is recorded when a loss has been confirmed by an updated appraisal or other appropriate valuation of the collateral. The Bank charges-off residential and consumer loans, or portions thereof, when the Bank reasonably determines the amount of the loss. The Bank adheres to delinquency thresholds established by applicable regulatory guidance to determine the charge-off timeframe for these loans. Loans at these delinquency thresholds for which the Bank can clearly document that the loan is both well-secured and in the process of collection, such that collection will occur regardless of delinquency status, need not be charged off. For all classes, all interest accrued but not collected for loans that are placed on nonaccrual or charged off is reversed against interest income. The interest on these loans is accounted for on the cash basis or cost recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Nonaccrual loans are returned to accrual status when, in the opinion of management, the financial position of the borrower indicates there is no longer any reasonable doubt as to the timely collection of interest or principal. The Bank requires a period of satisfactory performance of not less than six months before returning a nonaccrual loan to accrual status. When cash payments are received on impaired loans in each loan class, the Bank records the payment as interest income unless collection of the remaining recorded principal amount is doubtful, at which time payments are used to reduce the principal balance of the loan. Troubled debt restructured loans recognize interest income on an accrual basis at the renegotiated rate if the loan is in compliance with the modified terms, no principal reduction has been granted and the loan has demonstrated the ability to perform in accordance with the renegotiated terms for a period of at least six months. Allowance for Loan Losses The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to income. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of allocated and general components. The allocated component relates to loans that are classified as impaired. For those loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers nonimpaired loans and is based on historical charge-off experience by segment. The historical loss experience is determined by portfolio segment and is based on the actual loss history experienced by the Bank over the prior three years. Management believes the three-year historical loss experience methodology is appropriate in the current economic environment. Other adjustments (qualitative/environmental considerations) for each segment may be added to the allowance for each loan segment after an assessment of internal or external influences on credit quality that are not fully reflected in the historical loss or risk rating data. A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due, based on the loan’s current payment status and the borrower’s financial condition, including available sources of cash flows. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for non-homogenous type loans such as commercial, non-owner-occupied residential, multi-family, nonresidential and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price or the fair value of the collateral if the loan is collateral dependent. For impaired loans where the Bank utilizes the discounted cash flows to determine the level of impairment, the Bank includes the entire change in the present value of cash flows as bad debt expense. The fair values of collateral dependent impaired loans are based on independent appraisals of the collateral. In general, the Bank acquires an updated appraisal upon identification of impairment and annually thereafter for commercial, commercial real estate and multi-family loans. If the most recent appraisal is over a year old, and a new appraisal is not performed, due to lack of comparable values or other reasons, the existing appraisal is utilized and discounted based on the age of the appraisal, condition of the subject property and overall economic conditions. After determining the collateral value as described, the fair value is calculated based on the determined collateral value less selling expenses. The potential for outdated appraisal values is considered in our determination of the allowance for loan losses through our analysis of various trends and conditions including the local economy, trends in charge-offs and delinquencies, etc. and the related qualitative adjustments assigned by the Bank. Segments of loans with similar risk characteristics are collectively evaluated for impairment based on the segment’s historical loss experience adjusted for changes in trends, conditions and other relevant factors that affect repayment of the loans. Accordingly, the Bank does not separately identify individual consumer and residential loans for impairment measurements, unless such loans are the subject of a restructuring agreement due to financial difficulties of the borrower. In the course of working with borrowers, the Bank may choose to restructure the contractual terms of certain loans. In this scenario, the Bank attempts to work out an alternative payment schedule with the borrower in order to optimize collectability of the loan. Any loans that are modified are reviewed by the Bank to identify if a troubled debt restructuring (TDR) has occurred, which is when, for economic or legal reasons related to a borrower’s financial difficulties, the Bank grants a concession to the borrower that it would not otherwise consider. Terms may be modified to fit the ability of the borrower to repay in line with the borrower’s current financial status, and the restructuring of the loan may include the transfer of assets from the borrower to satisfy the debt, a modification of loan terms or a combination of the two. If such efforts by the Bank do not result in a satisfactory arrangement, the loan is referred to legal counsel, at which time foreclosure proceedings are initiated. At any time prior to a sale of the property at foreclosure, the Bank may terminate foreclosure proceedings if the borrower is able to work out a satisfactory payment plan. It is the Bank’s policy that any restructured loans on nonaccrual status prior to being restructured remain on nonaccrual status until six months of satisfactory borrower performance, at which time management would consider its return to accrual status. If a loan was accruing at the time of restructuring, the Bank reviews the loan to determine if it is appropriate to continue the accrual of interest on the restructured loan. With regard to determination of the amount of the allowance for credit losses, troubled debt restructured loans are considered to be impaired. As a result, the determination of the amount of impaired loans for each portfolio segment within troubled debt restructurings is the same as detailed previously. Premises and Equipment Depreciable assets are stated at cost less accumulated depreciation. Depreciation is charged to expense using the straight-line method over the estimated useful lives of the assets. Federal Home Loan Bank Stock Federal Home Loan Bank (“FHLB”) stock is a required investment for institutions that are members of the FHLB system and the transfer of the stock is substantially restricted. The required investment in the common stock is based on a predetermined formula. FHLB stock is carried at cost less an impairment, which approximates fair value. FHLB stock is evaluated for impairment on an annual basis. Bank Owned Life Insurance The Bank has purchased life insurance on certain employees. Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Foreclosed Assets Held for Sale Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value less cost to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in net income or expense from foreclosed assets. At June 30, 2022 and 2021, there were no foreclosed residential real estate properties recorded as a result of obtaining physical possession of the property. At June 30, 2022, the Bank had one loan of $39,000 secured residential real estate in process of foreclosure, subsequent to that date, the buyer brought the loan current and the foreclosure process has ceased. At June 30, 2021, there were no loans secured by residential real estate property for which formal foreclosure proceeds are in process. Income Taxes The Bank accounts for income taxes in accordance with income tax accounting guidance (ASC 740, Income Taxes Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. Tax positions are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances and information available at the reporting date and is subject to management’s judgment. If necessary, the Bank recognizes interest and penalties on income taxes as a component of income tax expense. With a few exceptions, the Bank is no longer subject to examination by tax authorities for calendar years before 2019. As of June 30, 2022, the Bank had no material uncertain income tax positions. Comprehensive Income (Loss) Comprehensive income consists of net income and other comprehensive income (loss), net of applicable income taxes. Other comprehensive income (loss) includes unrealized appreciation (depreciation) on available-for-sale securities and, if necessary, unrealized appreciation (depreciation) on available-for-sale securities for which a portion of an other-than-temporary impairment has been recognized in income. Accumulated other comprehensive loss consists solely of the cumulative unrealized gains and losses on available-for-sale securities, net of tax. Revenue Recognition The Bank accounts for revenue recognition in accordance with Accounting Standards Update (ASU) 2014-09 "Revenue from Contracts with Customers" (Accounting Standards Codification (ASC) 606). ASC 606 provides that an entity should recognize revenue to depict the transfer of promised goods and services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Interest income, net securities gains (losses) and income from bank-owned life insurance are not included within the scope of ASC 606. For the revenue streams in the scope of ASC 606, service charges on deposits and electronic banking fees, there are no significant judgments related to the amount and timing of revenue recognition. All of the Bank’s in scope revenue from contracts with customers is recognized within other noninterest income. Deposit Services. ​

Future Change In Accounting Principle
Future Change in Accounting Principle	Note 2: The FASB issued ASU No. 2016- 13, Financial Instruments—Credit Losses (Topic 326) The CECL model utilizes a lifetime “expected credit loss” measurement objective for the recognition of credit losses for loans, held-to-maturity securities and other receivables at the time the financial asset is originated or acquired. The expected credit losses are adjusted each period for changes in expected lifetime credit losses. For available-for-sale securities where fair value is less than cost, credit-related impairment, if any, will be recognized in an allowance for credit losses and adjusted each period for changes in expected credit risk. This model replaces the multiple existing impairment models, which generally require that a loss be incurred before it is recognized. The CECL model represents a significant change from existing practice and may result in material changes to the Bank’s accounting for financial instruments. The Bank is evaluating the effect ASU 2016-13 will have on its financial statements and related disclosures. The impact of the ASU will depend upon the state of the economy and the nature of our portfolios at the date of adoption. The new standard is effective for the Bank for fiscal years beginning after December 15, 2022 (July 1, 2023 as to the Bank), including interim periods within those fiscal years.

Expected maturities will differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Available-for-sale ​ ​ Amortized ​ Fair ​ Cost Value Within one year ​ $ — ​ $ — One to five years ​ 6,000,000 ​ 5,681,280 Five to ten years ​ 950,155 ​ 853,968 After ten years ​ 3,173,719 ​ 2,558,204 ​ ​ ​ 10,123,874 ​ ​ 9,093,452 Mortgage-backed GSEs ​ 17,022,130 ​ 15,400,958 Totals ​ $ 27,146,004 ​ $ 24,494,410 ​ The carrying value of securities pledged as collateral, to secure public deposits and for other purposes, was $4,652,000 and at Proceeds from sales of securities totaled $9,708,000 during the fiscal year ended June 30, 2022. Such sales resulted in realized losses of $291,000. There were no sales of securities during the fiscal year ended June 30, 2021. Certain investments in debt securities are reported in the financial statements at an amount less than their historical cost. Total fair value of these investments at June 30, 2022 and 2021, was $22,516,560 and $20,458,896, which is approximately 92 percent and 72 percent, respectively, of the fair value of the Bank’s total investment portfolio. These declines primarily resulted from changes in market interest rates. Based on evaluation of available evidence, including recent changes in market interest rates and information obtained from regulatory filings, management believes the declines in fair value for these securities are temporary. Should the impairment of any of these securities become other than temporary, the cost basis of the investment will be reduced and the resulting loss recognized in net income in the period the other-than-temporary impairment is identified. The following tables show the Bank’s investments’ gross unrealized losses and fair value of the Bank’s investments with unrealized losses that are not deemed to be other-than-temporarily impaired, aggregated by investment class and length of time that individual securities have been in a continuous unrealized loss position at June 30, 2022 and 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2022 ​ ​ Less than 12 Months 12 Months or More Total ​ ​ Fair Unrealized ​ Fair Unrealized ​ Fair Unrealized Description of Securities ​ Value ​ Losses ​ Value ​ Losses ​ Value ​ Losses U.S. Government agencies ​ $ 5,681,280 ​ $ 318,720 ​ $ — ​ $ — ​ $ 5,681,280 ​ $ 318,720 Mortgage-backed Government ​ ​ ​ ​ ​ ​ Sponsored Enterprises (GSEs) ​ 8,327,314 ​ 802,556 ​ 5,095,794 ​ 827,021 ​ 13,423,108 ​ 1,629,577 State and political subdivisions ​ 1,856,557 ​ 347,775 ​ 1,555,615 ​ 363,927 ​ 3,412,172 ​ 711,702 Total temporarily impaired securities ​ $ 15,865,151 ​ $ 1,469,051 ​ $ 6,651,409 ​ $ 1,190,948 ​ $ 22,516,560 ​ $ 2,659,999 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2021 ​ ​ Less than 12 Months 12 Months or More Total ​ ​ Fair Unrealized ​ Fair Unrealized ​ Fair Unrealized Description of Securities ​ Value ​ Losses ​ Value ​ Losses ​ Value ​ Losses U.S. Government agencies ​ $ 8,907,020 ​ $ 92,068 ​ $ — ​ $ — ​ $ 8,907,020 ​ $ 92,068 Mortgage-backed Government ​ ​ ​ ​ ​ ​ Sponsored Enterprises (GSEs) ​ 9,571,406 ​ 130,703 ​ 89,672 ​ 362 ​ 9,661,078 ​ 131,065 State and political subdivisions ​ 1,890,798 ​ 38,195 ​ — ​ — ​ 1,890,798 ​ 38,195 Total temporarily impaired securities ​ $ 20,369,224 ​ $ 260,966 ​ $ 89,672 ​ $ 362 ​ $ 20,458,896 ​ $ 261,328 ​ U.S. Government Agencies and State and Political Subdivisions Unrealized losses on these securities have not been recognized into income because the issuers’ bonds are of high credit quality, values have only been impacted by changes in interest rates since the securities were purchased, and the Bank has the intent and ability to hold the securities for the foreseeable future. The fair value is expected to recover as the bonds approach the maturity date. Mortgage-backed GSE’s The unrealized losses on the Bank’s investment in residential mortgage-backed securities were caused by changes in interest rates and illiquidity. The Bank expects to recover the amortized cost basis over the term of the securities. Because the decline in market value is attributable to changes in interest rates and illiquidity, and not credit quality, and because the Bank does not intend to sell the investments and it is not more likely than not the Bank will be required to sell the investments before recovery of their amortized cost basis, which may be maturity, the Bank does not consider those investments to be other-than-temporarily impaired at June 30, 2022.

The main risks are changes in the value of the collateral and changes in the economy or borrowers’ business operations. Management specifically considers unemployment and changes in real estate values in the Bank’s market area. Residential Real Estate These loans include first liens, junior liens and construction loans on 1-4 family residential real estate (both owner and non-owner occupied). The main risks for these loans are changes in the value of the collateral and stability of the local economic environment and its impact on the borrowers’ employment. Management specifically considers unemployment and changes in real estate values in the Bank’s market area. Multifamily These loans include loans on residential real estate secured by property with five or more units. The main risks are changes in the value of the collateral, ability of borrowers to collect rents, vacancy and changes in the tenants’ employment status. Management specifically considers unemployment and changes in real estate values in the Bank’s market area. Agriculture Real Estate These loans include loans on farm ground, vacant land for development and loans on commercial real estate. The main risks are changes in the value of the collateral and changes in the economy or borrowers’ business operations. Management specifically considers unemployment and changes in real estate values in the Bank’s market area. Construction and Land Real Estate These loans include construction loans for 1-4 family residential and commercial properties (both owner and non-owner occupied) and first liens on land. The main risks for construction loans include uncertainties in estimating costs of construction and in estimating the market value of the completed project. The main risks for land loans are changes in the value of the collateral and stability of the local economic environment. Management specifically considers unemployment and changes in real estate values in the Bank’s market area. HELOC These loans are generally secured by owner-occupied 1-4 family residences. The main risks for these loans are changes in the value of the collateral and stability of the local economic environment and its impact on the borrowers’ employment. Management specifically considers unemployment and changes in real estate values in the Bank’s market area. Commercial and Industrial The commercial and industrial portfolio includes loans to commercial customers for use in financing working capital needs, equipment purchases and expansions. The loans in this category are repaid primarily from the cash flow of a borrower’s principal business operation. Credit risk in these loans is driven by creditworthiness of the borrower and the economic conditions that impact the cash flow stability from business operations. Consumer Loans These loans include vehicle loans, share loans and unsecured loans. The main risks for these loans are the depreciation of the collateral values (vehicles) and the financial condition of the borrowers. Major employment changes are specifically considered by management.

This amount represents an allocation of income to bad debt deductions for tax purposes only. Reduction of amounts so allocated for purposes other than tax bad debt losses or adjustments arising from carryback of net operating losses would create income for tax purposes only, which would be subject to the then-current corporate income tax rate. The deferred income tax liability on the preceding amount that would have been recorded if it was expected to reverse into taxable income in the foreseeable future was approximately $375,000 at June 30, 2022 and 2021.

Regulatory Matters	Note 9: The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities and certain off-balance-sheet items as calculated under U.S. GAAP reporting requirements and regulatory capital standards. The Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Furthermore, the Bank’s regulators could require adjustments to regulatory capital not reflected in these financial statements. On November 13, 2019, the federal regulators finalized and adopted a regulatory capital rule establishing a new community bank leverage ratio (CBLR), which became effective on January 1, 2020. The intent of the CBLR is to provide a simple alternative measure of capital adequacy for electing qualifying depository institutions and depository institution holding companies, as directed under the Economic Growth, Regulatory Relief, and Consumer Protection Act i.e. two Coronavirus Aid, Relief, and Economic Security Act

Related Party Transactions	Note 10: The Bank had loans outstanding to certain of its executive officers, directors and their related interests, in the amount of approximately $4,151,000, of which $2,200,000 is committed and undispersed, and $5,154,000, at June 30, 2022 and 2021, respectively. During this time, there were $2.0 of principal additions while total reductions associated with these loans were $3.0 million. In management’s opinion, such loans and other extensions of credit and deposits were made in the ordinary course of business and were made on substantially the same terms (including interest rates and collateral) as those prevailing at the time for comparable transactions with other persons. Further, in management’s opinion, these loans did not involve more than normal risk of collectability or present other unfavorable features. Deposits from related parties held by the Bank at June 30, 2022 and 2021, totaled approximately $2,394,000 and $2,563,000, respectively.

Employee Benefits	Note 11: The Bank participates in a multi-employer defined benefit pension fund through Pentegra Retirement Services (Plan). More specifically, the plan number is 333 and the employer ID number is 13-5645888 Employee Retirement Income and Security Act of 1974 The Plan is a single plan under Internal Revenue Code Section 413(c) and, as a result, all of the assets stand behind all of the liabilities. Accordingly, under the Plan contributions made by a participating employer may be used to provide benefits to participants of other participating employers. The Plan had been maintained for all full-time employees who have been employed for a period longer than one year. In March 2016, the Bank froze its participation in the Plan for new employees and curtailed future benefits for existing employees. Current costs are funded as incurred. The Bank’s contributions to the fund are based on covered employees’ ages and salaries. Pension expense was approximately $96,000 and $202,000 for the fiscal years ended June 30, 2022 and 2021, respectively. The data available from administrators of the multi-employer plan is not sufficient to determine the Bank’s portion of accumulated benefit obligation or its portion of the net assets of the Plan. Under ERISA, a contributor to a multi-employer pension plan may be liable in the event of complete or partial withdrawal for the benefit payments guaranteed under ERISA. 401(k) Plan The Bank sponsors a 401(k) profit sharing plan covering substantially all employees. Employees are eligible to participate once they have reached age 21 Salary Continuation Plan On August 1, 2016, the Bank entered into a salary continuation plan with the Bank’s former President to provide additional retirement benefits for the life of the former President, with a guaranteed payout period of 15 years. The plan is intended to be an unfunded, non-qualified deferred compensation plan. The Bank’s expense relative to the plan totaled approximately $10,000 and $21,000 for the years ended June 30, 2022 and 2021, respectively. The Bank’s liability related to the plan totaled approximately $177,000 and $179,000 as of June 30, 2022 and 2021, respectively.

Disclosures about Fair Value of Assets and Liabilities
Disclosures about Fair Value of Assets and Liabilities	Note 12: Fair value is the exchange price that would be received to sell 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 at the measurement date. Fair value measurements must maximize the use of observable inputs and minimize the use of unobservable inputs. There is a hierarchy of three levels of inputs that may be used to measure fair value: Level 1 Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2 Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3 Significant unobservable inputs that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Recurring Measurements The following table presents the fair value measurements of assets recognized in the accompanying balance sheets measured at fair value on a recurring basis and the level within the fair value hierarchy in which the fair value measurements fall at June 30, 2022 and 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements Using ​ ​ ​ ​ ​ Quoted Prices in ​ ​ ​ ​ Significant ​ ​ ​ Active Markets for Significant Other Unobservable ​ ​ Fair Identical Assets Observable Inputs Inputs ​ Value (Level 1) (Level 2) (Level 3) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2022 ​ ​ ​ ​ U.S. Government agencies ​ $ 5,681,280 ​ $ — ​ $ 5,681,280 ​ $ — Mortgage-backed GSEs ​ 15,400,958 ​ — ​ 15,400,958 ​ — State and political subdivisions ​ 3,412,172 ​ — ​ 3,412,172 ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2021 ​ ​ ​ ​ U.S. Government agencies ​ $ 9,907,300 ​ $ — ​ $ 9,907,300 ​ $ — Mortgage-backed GSEs ​ 15,097,301 ​ — ​ 15,097,301 ​ — State and political subdivisions ​ 3,521,819 ​ — ​ 3,521,819 ​ — ​ Following is a description of the valuation methodologies used for assets measured at fair value on a recurring basis and recognized in the accompanying balance sheets, as well as the general classification of such assets pursuant to the valuation hierarchy. There are no liabilities measured at fair value on a recurring basis. There have been no significant changes in the valuation techniques during the year ended June 30, 2022. Available-for-sale Securities Where quoted market prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. If quoted market prices are not available, then fair values are estimated by using quoted prices of securities with similar characteristics or independent asset pricing services and pricing models, the inputs of which are market-based or independently sourced market parameters, including, but not limited to, yield curves, interest rates, volatilities, prepayments, defaults, cumulative loss projections and cash flows. Such securities are classified in Level 2 of the valuation hierarchy. In certain cases where Level 1 or Level 2 are not available, securities are classified within Level 3 of the hierarchy. The Bank had no Level 3 securities. Nonrecurring Measurements The Bank had no assets or liabilities measured at fair value on a nonrecurring basis at June 30, 2022. At June 30, 2021, the Bank had one loan measured at fair value with a carrying value of $60,000. ​ The estimated fair values of the Bank’s financial instruments not carried at fair value on the balance sheets are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Carrying Fair Fair Value Measurements Using ​ Value Value (Level 1) (Level 2) (Level 3) June 30, 2022 ​ ​ ​ ​ ​ Financial assets: ​ ​ ​ ​ ​ Cash and due from banks ​ $ 36,711,842 ​ $ 36,711,842 ​ $ 36,711,842 ​ $ — ​ $ — Interest-bearing time deposits ​ 1,470,000 ​ 1,470,000 ​ 1,470,000 ​ — ​ — Loans, net ​ 77,710,188 ​ 73,828,181 ​ — ​ — ​ 73,828,181 FHLB Stock ​ 1,012,900 ​ 1,012,900 ​ — ​ 1,012,900 ​ — Accrued interest receivable ​ 219,195 ​ 219,195 ​ 219,195 ​ — ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial liabilities: ​ ​ ​ ​ ​ Deposits ​ 109,990,209 ​ 109,936,154 ​ 74,773,154 ​ — ​ 35,163,000 Accrued interest payable ​ 5 ​ 5 ​ 5 ​ — ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2021 ​ ​ ​ ​ ​ Financial assets: ​ ​ ​ ​ ​ Cash and due from banks ​ $ 11,660,839 ​ $ 11,660,839 ​ $ 11,660,839 ​ $ — ​ $ — Interest-bearing time deposits ​ 4,890,000 ​ 4,890,000 ​ 4,890,000 ​ — ​ — Loans, net ​ 74,384,207 ​ 74,574,181 ​ — ​ — ​ 74,574,181 FHLB Stock ​ 1,012,900 ​ 1,012,900 ​ — ​ 1,012,900 ​ — Accrued interest receivable ​ 193,018 ​ 193,018 ​ 193,018 ​ — ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial liabilities: ​ ​ ​ ​ ​ Deposits ​ 100,922,890 ​ 101,367,630 ​ 62,421,630 ​ — ​ 38,946,000 Accrued interest payable ​ 7 ​ 7 ​ 7 ​ — ​ — ​ Limitations: Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Bank’s entire holdings of a particular financial instrument. Fair value estimates may not be realizable in an immediate settlement of the instrument. In some instances, there are no quoted market prices for the Bank’s various financial instruments, in which case fair values may be based on estimates using present value or other valuation techniques, or based on judgments regarding future expected loss experience, current economic conditions, risk characteristic of the financial instruments, or other factors. Those techniques are significantly affected by the assumptions used, including the discount rate and estimate of future cash flows. Subsequent changes in assumptions could significantly affect the estimates.

Commitments and Credit Risks	Note 13: Commitments to originate loans are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since a portion of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Each customer’s creditworthiness is evaluated on a case-by-case basis. The amount of collateral obtained, if deemed necessary, is based on management’s credit evaluation of the counterparty. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, commercial real estate and residential real estate. Lines of credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Lines of credit generally have fixed expiration dates.

Subsequent Events	Note 16: On March 3, 2022, the Board of Directors of the Bank adopted a plan of conversion (Plan). The Plan was subject to the approval of the Office of the Comptroller of the Currency and the approval by the affirmative vote of at least a majority of the total votes eligible to be cast by the voting members of the Bank at a special meeting. The Plan provided for the Bank to convert into a stock savings bank structure with the establishment of a stock holding company (VWF Bancorp, Inc.), as parent of the Bank. The Bank converted to the stock form of ownership, followed by the issuance of all of the Bank’s outstanding stock to VWF Bancorp, Inc. Pursuant to the Plan, the Bank determined the total offering value and number of shares of common stock based upon an independent appraiser’s valuation. At June 30, 2022, the Bank had collected $15.3 million in stock subscription orders. The conversion was completed on July 13, 2022, with VWF Bancorp Inc. shares issued totaling 1,922,924. The stock was issued at $10.00 per share. Total proceeds from the offering were $19.2 million before consideration of costs of the offering. In addition, the Bank’s Board of Directors adopted an employee stock ownership plan (ESOP) which subscribed for 8% of the common stock sold in the offering, or 153,834 shares. VWF Bancorp, Inc. is organized as a corporation under the laws of the State of Maryland and owns all of the outstanding common stock of the Bank as of completion of the conversion. The costs of issuing the common stock were deferred and deducted from the sales proceeds of the offering. Deferred conversion costs totaled approximately $807,000 at June 30, 2022. The Bank had incurred no deferred conversion costs as of June 30, 2021. At the completion of the conversion to stock form, the Bank established a liquidation account in the amount of retained earnings contained in the final prospectus. The liquidation account will be maintained for the benefit of eligible savings account holders who maintain deposit accounts in the Bank after conversion. The conversion will be accounted for as a change in corporate form with the historic basis of the Bank’s assets, liabilities and equity unchanged as a result. VWF Bancorp, Inc. is an emerging growth company, and, for as long as it continues to be an emerging growth company, it may choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to “emerging growth companies.” VWF Bancorp, Inc. intends to use the extended transition period to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. Accordingly, its financial statements may not be comparable to the financial statements of public companies that comply with such new or revised accounting standards. ​ ​

Nature of Operations and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Jun. 30, 2022
Nature of Operations and Summary of Significant Accounting Policies
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, valuation of deferred tax assets and fair values of financial instruments.
Change in Accounting Principle	Change in Accounting Principle In March 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2017-08 Premium Amortization on Purchased Callable Debt Securities . The Bank adopted ASU 2017-08 effective July 1, 2020, as required. As provided for in the ASU, a cumulative effect adjustment, representing a charge of $64,489, was recorded to retained earnings upon adoption, which equaled the difference at that date between use of the shorter amortization period to the call date for securities affected by the change.
Cash Equivalents	Cash Equivalents The Bank considers all liquid investments with original maturities of three months or less to be cash equivalents. At June 30, 2022 none of the Bank’s cash accounts at nonfederal government or nongovernmental agencies exceeded FDIC insurance limits.
Interest-bearing Time Deposits in Banks	Interest-bearing Time Deposits in Banks Interest-bearing time deposits have original maturities greater than one year and are carried at cost.
Debt Securities	Debt Securities Debt securities held by the Bank generally are classified and recorded in the financial statements as follows: Classified as ​ Description ​ Recorded at Held to maturity (HTM) ​ Certain debt securities that management has the positive intent and ability to hold to maturity ​ Amortized cost ​ ​ ​ ​ ​ ​ ​ Trading ​ Securities that are bought and held principally for the purpose of selling in the near term and, therefore, held for only a short period of time ​ Fair value, with changes in fair value included in earnings ​ ​ ​ ​ ​ ​ ​ Available for sale (AFS) ​ Securities not classified as HTM or trading ​ Fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income ​ ​ Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities, identified as the call date as to premiums and maturity date as to discounts. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. When the fair value of securities is below amortized cost, the Bank’s accounting treatment for an other-than-temporary impairment (OTTI) is as follows: ​ ​ Accounting Treatment for OTTI ​ ​ Components ​ Circumstances of Impairment Credit Remaining ​ Considerations ​ Component ​ Portion ​ Not intended for sale and more likely than not that the Bank will not have to sell before recovery of cost basis ​ Recognized in earnings ​ Recognized in other comprehensive income ​ ​ ​ ​ ​ ​ ​ Intended for sale or more likely than not that the Bank will be required to sell before recovery of cost basis ​ Recognized in earnings ​ ​ For held-to-maturity debt securities, the amount of OTTI recorded in other comprehensive income for the noncredit portion of a previous OTTI is amortized prospectively over the remaining life of the security on the basis of the timing of future estimated cash flows of the security. When a credit loss component is separately recognized in earnings, the amount is identified as the total of principal cash flows not expected to be received over the remaining term of the security, as projected based on cash flow projections. The Bank recognized no other-than-temporary impairments on debt securities in 2022 or 2021.
Loans	Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding principal balances adjusted for unearned income, charge-offs, the allowance for loan losses and any unamortized deferred fees or costs on originated loans and unamortized premiums or discounts on purchased loans. For loans amortized at cost, interest income is accrued based on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, as well as premiums and discounts, are deferred and amortized as a level yield adjustment over the respective term of the loan. For all loan portfolio segments except residential and consumer loans, the Bank promptly charges-off loans, or portions thereof, when available information confirms that specific loans are uncollectible based on information that includes, but is not limited to, (1) the deteriorating financial condition of the borrower, (2) declining collateral values, and/or (3) legal action, including bankruptcy, that impairs the borrower’s ability to adequately meet its obligations. For impaired loans that are considered to be solely collateral dependent, a partial charge-off is recorded when a loss has been confirmed by an updated appraisal or other appropriate valuation of the collateral. The Bank charges-off residential and consumer loans, or portions thereof, when the Bank reasonably determines the amount of the loss. The Bank adheres to delinquency thresholds established by applicable regulatory guidance to determine the charge-off timeframe for these loans. Loans at these delinquency thresholds for which the Bank can clearly document that the loan is both well-secured and in the process of collection, such that collection will occur regardless of delinquency status, need not be charged off. For all classes, all interest accrued but not collected for loans that are placed on nonaccrual or charged off is reversed against interest income. The interest on these loans is accounted for on the cash basis or cost recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Nonaccrual loans are returned to accrual status when, in the opinion of management, the financial position of the borrower indicates there is no longer any reasonable doubt as to the timely collection of interest or principal. The Bank requires a period of satisfactory performance of not less than six months before returning a nonaccrual loan to accrual status. When cash payments are received on impaired loans in each loan class, the Bank records the payment as interest income unless collection of the remaining recorded principal amount is doubtful, at which time payments are used to reduce the principal balance of the loan. Troubled debt restructured loans recognize interest income on an accrual basis at the renegotiated rate if the loan is in compliance with the modified terms, no principal reduction has been granted and the loan has demonstrated the ability to perform in accordance with the renegotiated terms for a period of at least six months.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to income. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of allocated and general components. The allocated component relates to loans that are classified as impaired. For those loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers nonimpaired loans and is based on historical charge-off experience by segment. The historical loss experience is determined by portfolio segment and is based on the actual loss history experienced by the Bank over the prior three years. Management believes the three-year historical loss experience methodology is appropriate in the current economic environment. Other adjustments (qualitative/environmental considerations) for each segment may be added to the allowance for each loan segment after an assessment of internal or external influences on credit quality that are not fully reflected in the historical loss or risk rating data. A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due, based on the loan’s current payment status and the borrower’s financial condition, including available sources of cash flows. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for non-homogenous type loans such as commercial, non-owner-occupied residential, multi-family, nonresidential and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price or the fair value of the collateral if the loan is collateral dependent. For impaired loans where the Bank utilizes the discounted cash flows to determine the level of impairment, the Bank includes the entire change in the present value of cash flows as bad debt expense. The fair values of collateral dependent impaired loans are based on independent appraisals of the collateral. In general, the Bank acquires an updated appraisal upon identification of impairment and annually thereafter for commercial, commercial real estate and multi-family loans. If the most recent appraisal is over a year old, and a new appraisal is not performed, due to lack of comparable values or other reasons, the existing appraisal is utilized and discounted based on the age of the appraisal, condition of the subject property and overall economic conditions. After determining the collateral value as described, the fair value is calculated based on the determined collateral value less selling expenses. The potential for outdated appraisal values is considered in our determination of the allowance for loan losses through our analysis of various trends and conditions including the local economy, trends in charge-offs and delinquencies, etc. and the related qualitative adjustments assigned by the Bank. Segments of loans with similar risk characteristics are collectively evaluated for impairment based on the segment’s historical loss experience adjusted for changes in trends, conditions and other relevant factors that affect repayment of the loans. Accordingly, the Bank does not separately identify individual consumer and residential loans for impairment measurements, unless such loans are the subject of a restructuring agreement due to financial difficulties of the borrower. In the course of working with borrowers, the Bank may choose to restructure the contractual terms of certain loans. In this scenario, the Bank attempts to work out an alternative payment schedule with the borrower in order to optimize collectability of the loan. Any loans that are modified are reviewed by the Bank to identify if a troubled debt restructuring (TDR) has occurred, which is when, for economic or legal reasons related to a borrower’s financial difficulties, the Bank grants a concession to the borrower that it would not otherwise consider. Terms may be modified to fit the ability of the borrower to repay in line with the borrower’s current financial status, and the restructuring of the loan may include the transfer of assets from the borrower to satisfy the debt, a modification of loan terms or a combination of the two. If such efforts by the Bank do not result in a satisfactory arrangement, the loan is referred to legal counsel, at which time foreclosure proceedings are initiated. At any time prior to a sale of the property at foreclosure, the Bank may terminate foreclosure proceedings if the borrower is able to work out a satisfactory payment plan. It is the Bank’s policy that any restructured loans on nonaccrual status prior to being restructured remain on nonaccrual status until six months of satisfactory borrower performance, at which time management would consider its return to accrual status. If a loan was accruing at the time of restructuring, the Bank reviews the loan to determine if it is appropriate to continue the accrual of interest on the restructured loan. With regard to determination of the amount of the allowance for credit losses, troubled debt restructured loans are considered to be impaired. As a result, the determination of the amount of impaired loans for each portfolio segment within troubled debt restructurings is the same as detailed previously.
Premises and Equipment	Premises and Equipment Depreciable assets are stated at cost less accumulated depreciation. Depreciation is charged to expense using the straight-line method over the estimated useful lives of the assets.
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock Federal Home Loan Bank (“FHLB”) stock is a required investment for institutions that are members of the FHLB system and the transfer of the stock is substantially restricted. The required investment in the common stock is based on a predetermined formula. FHLB stock is carried at cost less an impairment, which approximates fair value. FHLB stock is evaluated for impairment on an annual basis.
Bank Owned Life Insurance	Bank Owned Life Insurance The Bank has purchased life insurance on certain employees. Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Foreclosed Assets Held for Sale	Foreclosed Assets Held for Sale Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value less cost to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in net income or expense from foreclosed assets. At June 30, 2022 and 2021, there were no foreclosed residential real estate properties recorded as a result of obtaining physical possession of the property. At June 30, 2022, the Bank had one loan of $39,000 secured residential real estate in process of foreclosure, subsequent to that date, the buyer brought the loan current and the foreclosure process has ceased. At June 30, 2021, there were no loans secured by residential real estate property for which formal foreclosure proceeds are in process.
Income Taxes	Income Taxes The Bank accounts for income taxes in accordance with income tax accounting guidance (ASC 740, Income Taxes Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. Tax positions are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances and information available at the reporting date and is subject to management’s judgment. If necessary, the Bank recognizes interest and penalties on income taxes as a component of income tax expense. With a few exceptions, the Bank is no longer subject to examination by tax authorities for calendar years before 2019. As of June 30, 2022, the Bank had no material uncertain income tax positions.
Comprehensive Income (Loss)	Comprehensive Income (Loss) Comprehensive income consists of net income and other comprehensive income (loss), net of applicable income taxes. Other comprehensive income (loss) includes unrealized appreciation (depreciation) on available-for-sale securities and, if necessary, unrealized appreciation (depreciation) on available-for-sale securities for which a portion of an other-than-temporary impairment has been recognized in income. Accumulated other comprehensive loss consists solely of the cumulative unrealized gains and losses on available-for-sale securities, net of tax.
Revenue Recognition	Revenue Recognition The Bank accounts for revenue recognition in accordance with Accounting Standards Update (ASU) 2014-09 "Revenue from Contracts with Customers" (Accounting Standards Codification (ASC) 606). ASC 606 provides that an entity should recognize revenue to depict the transfer of promised goods and services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Interest income, net securities gains (losses) and income from bank-owned life insurance are not included within the scope of ASC 606. For the revenue streams in the scope of ASC 606, service charges on deposits and electronic banking fees, there are no significant judgments related to the amount and timing of revenue recognition. All of the Bank’s in scope revenue from contracts with customers is recognized within other noninterest income. Deposit Services.
