Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organizational Structure and Nature of Operations	Note 1 – Organizational Structure and Nature of Operations Malvern Bancorp, Inc. (the “Company” or “Malvern Bancorp”), a Pennsylvania corporation, is a registered bank holding company registered under the Bank Holding Company Act of 1956, as amended (the “Holding Company Act”). Malvern Bancorp is the holding company for Malvern Bank, National Association (“Malvern Bank” or the “Bank”), a national bank that was originally organized in 1887 as a federally-chartered savings bank. The Company’s primary business is the ownership and operation of the Bank. The Bank’s principal business consists of attracting deposits from businesses and the general public and investing those deposits, together with borrowings and funds generated from operations, in commercial and multi-family real estate loans, one- to four-family residential real estate loans, construction and development loans, commercial business loans, home equity loans and lines of credit and other consumer loans, as well as investing in investment securities. We also maintain a portfolio of investment securities, primarily comprised of corporate bonds, mortgage-backed securities, U.S. agency and bank qualified municipal obligations. Malvern Bank now serves as one of the oldest banks headquartered on the Philadelphia Main Line. For more than a century, the Bank has been committed to helping people build prosperous communities as a trusted financial partner, forging lasting relationships through teamwork, respect and integrity. We derive substantially all of our income from our net interest income (i.e., the difference between the interest we receive on our loans and securities and the interest we pay on deposits and other borrowings). The Bank’s revenues are derived principally from interest on loans and investment securities, loan commitment and customer service fees and our mortgage banking operation. Deposits serve as the primary source of funding for our interest-earning assets, but we also generate non-interest revenue through insufficient funds fees, stop payment fees, safe deposit rental fees, card income, including credit and debit card interchange fees, gift card fees, and other miscellaneous fees. In addition, the Bank generates additional non-interest revenue associated with residential loan origination and sale, back to back customer swaps, loan servicing, late fees and merchant services. The Bank’s primary expenses are interest expense on deposits and borrowings, provisions for loan losses and general operating expenses. The Bank conducts business from its headquarters in Paoli, Pennsylvania, a suburb of Philadelphia, and through its nine other banking locations in Chester and Delaware counties, Pennsylvania, Morristown, New Jersey, its New Jersey regional headquarters and Palm Beach, Florida. The Bank also maintains representative offices in Wellington, Florida and Allentown, Pennsylvania. The Bank’s primary market niche is providing personalized service to its client base. The Bank has the following subsidiary interests: • The Bank owns 100 percent of Malvern Insurance Associates, LLC (“Malvern Associates”), a Pennsylvania limited liability company. Malvern Associates is a licensed insurance broker under Pennsylvania and New Jersey law. • Certain mortgage-backed securities of the Bank are held through Delaware statutory trusts, 5 percent of which are owned by the Bank and 95 percent of which are owned by Coastal Asset Management Co., a Delaware corporation which is wholly owned by the Bank. • The Bank owns 100 percent of Joliet 55 LLC., an Illinois limited liability company which holds an other real estate owned (“OREO”) asset. • The Bank owns a 10 percent non-controlling interest in Bell Rock Capital, LLC (“Bell Rock”), an investment advisor registered with the SEC. • The Bank owns a 3.39 percent interest in Bankers Settlement Services Capital Region, LLC, a Pennsylvania limited liability company which acts as a title insurance agent or agency. The banking industry is highly regulated. The Bank is supervised by the Office of the Comptroller of the Currency (the “OCC”), and the Company is supervised by the Board of Governors of the Federal Reserve Board (the “FRB”). In accordance with the subsequent events topic of the Financial Accounting Standards Board (“FASB”)

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2 – Summary of Significant Accounting Policies Basis of Presentation and Consolidation The consolidated financial statements at and for the years ended September 30, 2020 and 2019 include the accounts of Malvern Bancorp, Inc. and its subsidiaries. All significant intercompany transactions and balances have been eliminated. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) 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 consolidated financial statements and the reported amounts of income and expenses 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 loan losses and the valuation of DTAs. Significant Group Concentrations of Credit Risk Most of the Company’s activities are with customers located within Chester County, Pennsylvania and Morris County, New Jersey. Our lending efforts are also focused in Bucks County, Montgomery County and Delaware County, which are also in southeastern Pennsylvania, New Jersey and the New York metropolitan marketplace. Note 7 discusses the types of investment securities that the Company invests in. Note 8 discusses the types of lending that the Company engages in. The Company does not have any significant concentrations to any one industry or customer. Although the Company has a diversified portfolio, its debtor’s ability to honor their contracts is influenced by, among other factors, the region’s economy. Operating, Accounting and Reporting Considerations related to COVID-19 The COVID-19 pandemic has negatively impacted the global economy. In response to the crisis, the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act was passed by Congress and signed into law on March 27, 2020. The CARES Act provides an estimated $2.2 trillion to fight the COVID-19 pandemic and stimulate the economy by supporting individuals and businesses through loans, grants, tax changes, and other types of relief. Under Section 4013 of the CARES Act, and based upon regulatory guidance promulgated by federal banking regulators, qualifying short-term loan modifications resulting in payment deferrals that are attributable to the adverse impact of COVID-19, are not considered to be troubled debt restructurings (“TDRs”). • Accounting for Loan Modifications – The CARES Act provides that a financial institution may elect to suspend (1) the requirements under GAAP for certain loan modifications that would otherwise be categorized as a troubled debt restructure (“TDR”) and (2) any determination that such loan modifications would be considered a TDR, including the related impairment for accounting purposes. The suspension is applicable for the term of the loan modification that occurs during the applicable period for a loan that was not more than 30 days past due as of December 31, 2019. The suspension is not applicable to any adverse impact on the credit of a borrower that is not related to the pandemic. • Paycheck Protection Program – The CARES Act established the Paycheck Protection Program (“PPP”), an expansion of the Small Business Administration’s 7(a) loan program and the Economic Injury Disaster Loan Program (“EIDL”), administrated directly by the Small Business Administration (“SBA”). • Mortgage Forbearance – Under the CARES Act, through the earlier of December 31, 2020, mortgage customers experiencing financial hardship due to COVID-19 may request forbearance on the loan for up to 30 days, with up to two additional 30-day periods at the borrower’s request. Also in response to the COVID-19 pandemic, the Board of Governors of the Federal Reserve System (“FRB”), the Federal Deposit Insurance Corporation (“FDIC”), the National Credit Union Administration (“NCUA”), the Office of the Comptroller of the Currency (“OCC”), and the Consumer Financial Protection Bureau (“CFPB”), in consultation with the state financial regulators (collectively, the “agencies”) issued a joint interagency statement (issued March 22, 2020; revised statement issued April 7, 2020). Some of the provisions applicable to the Company include, but are not limited to: Note 2 - Summary of Significant Accounting Policies (Continued) • Accounting for Loan Modifications – Loan modifications that do not meet the conditions of the CARES Act may still qualify as a modification that does not need to be accounted for as a TDR. The agencies confirmed with FASB staff that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who are current prior to any relief are not TDRs. This includes short-term (e.g., six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or insignificant delays in payments. Loan modifications were made in accordance with Section 4013 of the CARES Act and the Interagency Statement on Loan Modifications and Reporting for Financial Institutions working with customers affected by COVID-19 and therefore were not classified as TDRs. • Past Due Reporting – With regard to loans not otherwise reportable as past due, financial institutions are not expected to designate loans with deferrals granted due to COVID-19 as past due because of the deferral. A loan’s payment date is governed by the due date stipulated in the legal agreements. If a financial institution agrees to a payment deferral, these loans would not be considered past due during the period of the deferral. • Nonaccrual Status and Charge-offs – During short-term COVID-19 modifications, these loans generally should not be reported as nonaccrual or as classified. Risks and Uncertainties On March 11, 2020, the World Health Organization declared the outbreak of COVID-19 a global pandemic. The COVID-19 pandemic has adversely affected, and may continue to adversely affect local, national and global economic activity. Actions taken to help mitigate the spread of COVID-19 include restrictions on travel, localized quarantines, and government-mandated closures of certain businesses. The spread of the outbreak has caused significant disruptions to the U.S. economy and has disrupted banking and other financial activity in the areas in which the Company operates. On March 3, 2020, the Federal Open Market Committee reduced the targeted federal funds interest rate range by 50 basis points to 1.00 percent to 1.25 percent. This range was further reduced to 0 percent to 0.25 percent on March 16, 2020. On March 27, 2020, the CARES Act was enacted to, among other provisions, provide emergency assistance for individuals, families and businesses affected by the COVID-19 pandemic. These reductions in interest rates and other effects of the COVID-19 pandemic may materially and adversely affect the Company's financial condition and results of operations in future periods. It is unknown how long the adverse conditions associated with the COVID-19 pandemic will last and what the complete financial effect will be to the Company. It is possible that estimates made in the financial statements could be materially and adversely impacted as a result of these conditions, including estimates regarding expected credit losses on loans receivable, and other-than-temporary impairment of investment securities. Cash and Cash Equivalents For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from depository institutions and interest-bearing deposits. The Company maintains cash deposits in other depository institutions that occasionally exceed the amount of deposit insurance available. Management periodically assesses the financial condition of these institutions and believes that the risk of any possible credit loss is minimal. The Company is required to maintain average reserve balances in vault cash with the Federal Reserve Bank based upon outstanding balances of deposit transaction accounts. Based upon the Company’s outstanding transaction deposit balances, the Bank maintained a deposit account with the Federal Reserve Bank of Philadelphia in the amount of zero at September 30, 2020 and 2019. Investment Securities Held-to-maturity (“HTM”) are securities that includes debt securities that the Company has the positive intent and the ability to hold to maturity. These securities are reported at amortized cost and adjusted for unamortized Note 2 - Summary of Significant Accounting Policies (Continued) premiums and discounts. Securities held for trading are securities that are bought and held principally for the purpose of selling in the near term; these securities are reported at fair value, with unrealized gains and losses reported in current earnings. At September 30, 2020 and 2019, the Company had no investment securities classified as trading. Debt securities that will be held for indefinite periods of time and equity securities, including securities that may be sold in response to changes in market interest or prepayment rates, needs for liquidity and changes in the availability of and the yield of alternative investments, are classified as available for sale. Realized gains and losses are recorded on the trade date and are determined using the specific identification method. Securities held as available for sale are reported at fair value, with unrealized gains and losses, net of tax, reported as a component of accumulated other comprehensive income (“AOCI”). Management determines the appropriate classification of investment securities at the time of purchase. Securities are evaluated on a quarterly basis, and more frequently when market conditions warrant such an evaluation, to determine whether declines in their value are other-than-temporary. To determine whether a loss in value is other-than-temporary, management utilizes criteria such as the reasons underlying the decline, the magnitude and duration of the decline and whether or not management intends to sell or expects that it is more likely than not that it will be required to sell the security prior to an anticipated recovery of the fair value. The term “other-than-temporary” is not intended to indicate that the decline is permanent, but indicates that the prospects for a near-term recovery of value is not necessarily favorable, or that there is a lack of evidence to support a realizable value equal to or greater than the carrying value of the investment. Once a decline in value for a debt security is determined to be other-than-temporary, the other-than-temporary impairment is separated into (a) the amount of the total other-than-temporary impairment related to a decrease in cash flows expected to be collected from the debt security (the credit loss) and (b) the amount of the total other-than-temporary impairment related to all other factors. The amount of the total other-than-temporary impairment related to the credit loss is recognized in earnings. The amount of the total other-than-temporary impairment related to all other factors is recognized in other comprehensive income. Loans Receivable The Company, through the Bank, grants mortgage, construction, commercial and consumer loans to customers. Substantially all of our loans are to individuals, businesses and real estate developers in Chester County, Pennsylvania and neighboring areas in southern Pennsylvania, New Jersey and the New York metropolitan marketplace, Delaware and Florida markets. The ability of the Company’s debtors to honor their contracts is dependent upon, among other factors, the real estate and general economic conditions in this area. Loans receivable that management has the intent and ability to hold until maturity or payoff are stated at their outstanding unpaid principal balances, net of an allowance for loan losses and any deferred fees and costs. Interest income is accrued on the unpaid principal balance. Loan origination fees and costs are deferred and recognized as an adjustment of the yield (interest income) of the related loans using the interest method. The Company is amortizing these amounts over the contractual lives of the loans. The loans receivable portfolio is segmented into residential loans, construction and development loans, commercial loans and consumer loans. The residential loan segment has one class, one- to four-family first lien residential mortgage loans. The construction and development loan segment consists of the following classes: residential and commercial and land loans. Residential construction loans are made for the acquisition of and/or construction on a lot or lots on which a residential dwelling is to be built. Commercial construction loans are made for the purpose of acquiring, developing and constructing a commercial structure. The commercial loan segment consists of the following classes: commercial real estate loans, multi-family real estate loans, and other commercial loans, which are also generally known as commercial and industrial loans or commercial business loans. The consumer loan segment consists of the following classes: home equity lines of credit, second mortgage loans and other consumer loans, primarily unsecured consumer lines of credit. For all classes of loans receivable, the accrual of interest is discontinued when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about further collection of principal or interest, even though the loan is currently performing. A loan may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan is placed on nonaccrual status, unpaid interest credited to income in the current year is reversed and unpaid interest accrued in prior years is charged against the allowance for loan losses. Interest received on nonaccrual loans, including impaired loans, generally is either applied against principal or reported as interest income, according to management’s judgment as to the Note 2 - Summary of Significant Accounting Policies (Continued) collectability of principal. Generally, loans are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time (generally six months) and the ultimate collectability of the total contractual principal and interest is no longer in doubt. The past due status of all classes of loans receivable is determined based on contractual due dates for loan payments. In addition to originating loans, the Company purchases consumer and mortgage loans from brokers in our market area. Such purchases are reviewed for compliance with our underwriting criteria before they are purchased, and are generally purchased without recourse to the seller. Premiums and discounts on purchased loans are amortized as adjustments to interest income using the effective yield method. Reserves for unfunded lending commitments represent management’s estimate of losses inherent in its unfunded loan commitments and is recorded in other liabilities on the consolidated statements of financial condition. Allowance for Loan Losses The allowance for credit losses consists of the allowance for loan losses. The allowance for loan losses represents management’s estimate of losses inherent in the loan portfolio as of the consolidated statement of financial condition date and is recorded as a reduction to loans. The allowance for loan losses (“ALLL”, “allowance”) is increased by the provision for loan losses and decreased by charge-offs, net of recoveries. Loans deemed to be uncollectible are charged against the allowance for loan losses, and subsequent recoveries, if any, are credited to the allowance. All, or part, of the principal balance of loans receivable are charged off to the allowance as soon as it is determined that the repayment or collateral recovery of all, or part, of the principal balance is highly unlikely. Non-residential consumer loans a The allowance for credit losses is maintained at a level considered adequate to provide for losses that can be reasonably estimated. Management performs a quarterly evaluation of the adequacy of the allowance. The allowance is based on the Company’s past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral, the composition of the loan portfolio, current economic conditions and other relevant factors. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant revision as more information becomes available. The allowance consists of specific, general and unallocated components. The specific component relates to loans that are classified as impaired. For loans that are classified as impaired, a specific reserve is recognized 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 pools of loans by loan class that are not considered impaired. These pools of loans are evaluated for loss exposure based upon historical loss rates for each of these classes of loans, as adjusted for qualitative factors. These qualitative risk factors include: 1. Lending policies and procedures, including underwriting standards and collection, charge-off, and recovery practices. 2. National, regional, and local economic and business conditions as well as the condition of various market segments, including the value of underlying collateral for collateral dependent loans. 3. The nature and volume of the loan portfolio and terms of loans. 4. The experience, ability, and depth of lending management and staff. 5. The volume and severity of past due, classified and nonaccrual loans as well as any other loan modifications. 6. The quality of the Company’s loan review system, and the degree of oversight by the Company’s Board of Directors. Note 2 - Summary of Significant Accounting Policies (Continued) 7. The existence and effect of any concentrations of credit and changes in the level of such concentrations. 8. Value of underlying collateral. 9. A single calculation figure which is subsequently applied to the loan portfolio by loan type (Commercial, Residential and Consumer) based upon the percent of each to total loans. It is derived from a review of a peer group consisting of ten banks with similar asset size within the same general geographic area of the Bank. The qualitative factors are applied to the historical loss rates for each class of loan. In addition, while not reported as a separate factor, changes in the value of underlying collateral (for regional property values) for collateral dependent loans is considered and addressed within the economic trends factor. A quarterly calculation is made adjusting the reserve allocation for each factor within a risk weighted range as it relates to each particular loan type, collateral type and risk rating within each segment. Data is gathered and evaluated through internal, regulatory, and government sources quarterly for each factor. An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. In addition, the allowance calculation methodology includes further segregation of loan classes into risk rating categories. The borrower’s overall financial condition, repayment sources, guarantors and value of collateral, if appropriate, are evaluated annually for commercial loans or when credit deficiencies arise, such as delinquent loan payments, for commercial and consumer loans. Credit quality risk ratings include categories of “pass,” “special mention,” “substandard” and “doubtful.” Assets classified as “Pass” are those protected by the current net worth and paying capacity of the obligor or by the value of the underlying collateral. Assets which do not currently expose the insured institution to sufficient risk to warrant classification as substandard or doubtful but possess certain identified weaknesses are required to be designated “special mention.” If uncorrected, the potential weaknesses may result in deterioration of the repayment prospects. An asset is considered “substandard” if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. “Substandard” assets include those characterized by the “distinct possibility” that the insured institution will sustain “some loss” if the deficiencies are not corrected. Assets classified as “doubtful” have all of the weaknesses inherent in those classified “substandard” with the added characteristic that the weaknesses present make “collection or liquidation in full,” on the basis of currently existing facts, conditions, and values, “highly questionable and improbable.” Residential Lending. Residential mortgage originations are secured primarily by properties located in the Company’s primary market area and surrounding areas. We currently originate fixed-rate, fully amortizing mortgage loans with maturities of 10 to 30 years. We also offer adjustable rate mortgage (“ARM”) loans where the interest rate either adjusts on an annual basis or is fixed for the initial one, three or seven years and then adjusts annually. We underwrite one- to four-family residential mortgage loans with loan-to-value ratios of up to 95 percent, provided that the borrower obtains private mortgage insurance on loans that exceed 80 percent of the appraised value or sales price, whichever is less, of the secured property. We also require that title insurance, hazard insurance and, if appropriate, flood insurance be maintained on all properties securing real estate loans. We require that a licensed appraiser from our list of approved appraisers perform and submit to us an appraisal on all properties secured by a first mortgage on one- to four-family first mortgage loans. In underwriting one- to four-family residential mortgage loans, the Company evaluates both the borrower’s ability to make monthly payments and the value of the property securing the loan. Most properties securing real estate loans made by the Company are appraised by independent fee appraisers reviewed and approved by the Bank’s third-party appraisal management companies. The Company generally requires borrowers to obtain an attorney’s title opinion or title insurance, and fire and property insurance (including flood insurance, if necessary) in an amount not less than the amount of the loan. Real estate loans originated by the Company generally contain a “due on sale” clause allowing the Company to declare the unpaid principal balance due and payable upon the sale of the security property. The Company has not engaged in sub-prime residential mortgage loan originations. Our single-family residential mortgage loans generally are underwritten on terms and documentation conforming to guidelines issued by The Federal Home Loan Mortgage Company, or Freddie Mac, and The Federal National Mortgage Association, or Fannie Mae. Note 2 - Summary of Significant Accounting Policies (Continued) Construction and Development Lending. We originate construction loans for residential and, to a lesser extent, commercial uses within our market area. We generally limit construction loans to builders and developers with whom we have an established relationship, or who are otherwise known to officers of the Bank. Our construction and development loans currently in the portfolio typically have variable rates of interest tied to the prime rate which improves the interest rate sensitivity of our loan portfolio. Construction and development loans generally are considered to involve a higher level of risk than one-to four-family residential lending, due to the concentration of principal in a limited number of loans and borrowers and the effect of economic conditions on developers, builders and projects. Additional risk is also associated with construction lending because of the inherent difficulty in estimating both a property’s value at completion and the estimated cost (including interest) to complete a project. The nature of these loans is such that they are more difficult to evaluate and monitor. In addition, speculative construction loans to a builder are not pre-sold and thus pose a greater potential risk than construction loans to individuals on their personal residences. In order to mitigate some of the risks inherent in construction lending, we inspect properties under construction, review construction progress prior to advancing funds, work with builders with whom we have established relationships, require annual updating of tax returns and other financial data of developers and obtain personal guarantees from the principals. Commercial Lending. Commercial and multi-family real estate loans generally present a higher level of risk than loans secured by one- to four-family residences. This greater risk is due to several factors, including the concentration of principal in a limited number of loans and borrowers, the effect of general economic conditions on income producing properties and the increased difficulty of evaluating and monitoring these types of loans. Furthermore, the repayment of loans secured by commercial and multi-family real estate is typically dependent upon the successful operation of the related real estate project. If the cash flow from the project is reduced (for example, if leases are not obtained or renewed, or a bankruptcy court modifies a lease term, or a major tenant is unable to fulfill its lease obligations), the borrower’s ability to repay the loan may be impaired. Most of the Company’s commercial business loans have been extended to finance local and regional businesses and include short-term loans to finance machinery and equipment purchases, inventory and accounts receivable. The commercial business loans which we originate may be either a revolving line of credit or for a fixed term of generally 10 years or less. Interest rates are adjustable, indexed to a published prime rate of interest, or fixed. Generally, equipment, machinery, real property or other corporate assets secure such loans. Personal guarantees from the business principals are generally obtained as additional collateral. Consumer Lending. The Company currently originates most of its consumer loans in its primary market area and surrounding areas. The Company originates consumer loans on both a direct and indirect basis. Consumer loans generally have higher interest rates and shorter terms than residential mortgage loans; however, they have additional credit risk due to the type of collateral securing the loan or in some case the absence of collateral. We are continuing to evaluate and monitor the credit conditions of our consumer loan borrowers and the real estate values of the properties securing our second mortgage loans as part of our on-going efforts to assess the overall credit quality of the portfolio in connection with our review of the allowance for loan losses. Consumer loans may entail greater credit risk than do residential mortgage loans, particularly in the case of consumer loans which are unsecured or are secured by rapidly depreciable assets, such as automobiles or recreational equipment. In such cases, any repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment of the outstanding loan balance as a result of the greater likelihood of damage, loss or depreciation. In addition, consumer loan collections are dependent on the borrower’s continuing financial stability, and thus are more likely to be affected by adverse personal circumstances. Furthermore, the application of various federal and state laws, including bankruptcy and insolvency laws, may limit the amount which can be recovered on such loans. Once all factor adjustments are applied, general reserve allocations for each segment are calculated, summarized and reported on the ALLL summary. ALLL final schedules, calculations and the resulting evaluation process are reviewed quarterly. In addition, Federal bank regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance and may require the Company to recognize additions to the allowance based on their judgments about information available to them at the time of their examination. Based on management’s comprehensive analysis of the loan portfolio, management believes the current level of the allowance for loan losses is adequate. Note 2 - Summary of Significant Accounting Policies (Continued) A loan is considered impaired when, based on current information and events, it is probable that the Company 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, cash flow, and the probability of collecting scheduled principal and interest payments when due. 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. A specific reserve is established for an impaired loan if its carrying value exceeds its estimated fair value. The estimated fair values of substantially all of the Company’s impaired loans are measured based on the estimated fair value of the loan’s collateral. For commercial loans secured by real estate, estimated fair values are determined primarily through third-party appraisals. When a real estate secured loan becomes impaired, a decision is made regarding whether an updated appraisal of the real estate is necessary. This decision is based on various considerations, including the age of the most recent appraisal, the loan-to-value ratio based on the original appraisal and the condition of the property. Appraised values are discounted to arrive at the estimated selling price of the collateral, which is considered to be the estimated fair value. The discounts also include estimated costs to sell the property. For commercial and industrial loans secured by non-real estate collateral, such as accounts receivable, inventory and equipment, estimated fair values are determined based on the borrower’s financial statements, inventory reports, accounts receivable aging or equipment appraisals or invoices. Indications of value from these sources are generally discounted based on the age of the financial information or the quality of the assets. Troubled Debt Restructurings Loans whose terms are modified are classified as TDRs if the Company grants such borrowers concessions and it is deemed that those borrowers are experiencing financial difficulty. Concessions granted under a troubled debt restructuring may be modified by means of extending the maturity date of the loan, reducing the interest rate on the loan to a rate which is below market, a combination of rate adjustments and maturity extensions, or by other means including covenant modifications, forbearances or other concessions. However, the Company generally only restructures loans by modifying the payment structure to interest only or by reducing the actual interest rate. We do not accrue interest on loans that were non-accrual prior to the TDR troubled debt restructurings . Management evaluates the ALLL with respect to TDRs under the same policy and guidelines as all other performing loans are evaluated with respect to the ALLL. In March 2020, various regulatory agencies, including the FRB and the FDIC issued an interagency statement on loan modifications and reporting for financial institutions working with customers affected by COVID-19. The interagency statement was effective immediately and impacted accounting for loan modifications. The agencies confirmed with the staff of the FASB that

Restatement Of Previously Issued Consolidated Financial Statements [Abstract]
Restatement of Previously Issued Consolidated Financial Statements	Note 3 - Restatement of Previously Issued Consolidated Financial Statements The consolidated financial statements for the year ended September 30, 2019 have been restated to reflect the correction of misstatements. We have also restated all amounts impacted within the Notes to the consolidated financial statements. The prior period restatement is related to two commercial loan participation agreements that were partial participation sales, originated by Malvern Bank and sold to other financial institutions. Upon further review of the two agreements for compliance with FASB ASC 860-10-40, which relates to sale accounting treatment of participation interests, it was determined that the two agreements should have been recorded as secured borrowing arrangements. The related balance sheet adjustment for treating such participation interests as secured borrowing arrangements as of September 30, 2019 is to gross up “Loans Receivable” by approximately $4.3 million and to record a “Secured Borrowing” of approximately $4.3 million. The related income statement adjustment for treating such participation interests as secured borrowing arrangements for the year ended September 30, 2019 is to increase interest income on loans and interest expense on long-term borrowings by approximately $180,000. Net income for the year ended September 30, 2019 does not change due to the adjustments. The related statement of cash flows adjustment for treating such participation interests as secured borrowing arrangements for the year ended September 30, 2019 is to decrease the “Net increase on loans” and to increase the “Repayment of other borrowed money” by approximately $25,000, which is the change in balance of the secured borrowings from the year ended September 30, 2018 to the year ended September 30, 2019.

Noninterest Income [Abstract]
Non-Interest Income	Note 4 – Non-Interest Income On October 1, 2018, the Company adopted the amendments of ASU 2014-09 - Revenue from Contracts with Customers (Topic 606) and all subsequent ASUs that modified Topic 606. A significant amount of the Company’s revenues is derived from net interest income on financial assets and liabilities, which are excluded from the scope of the amended guidance. Some sources of revenue included within non-interest income fall within the scope of Topic 606, while other sources do not. The Company recognizes revenue when the performance obligations related to the transfer of goods or services under the terms of the contract are satisfied. Some obligations are satisfied at a point in time while others are satisfied over a period of time. Revenue is recognized as the amount of consideration to which the Company expects to be entitled in exchange for transferring goods or services to a customer. When consideration includes a variable component, the amount of consideration attributable to variability is included in the transaction price only to the extent it is probable that significant revenue recognized will not be reversed when uncertainty associated with the variable consideration is subsequently resolved. The Company’s contracts generally do not contain terms that require significant judgement to determine the variability impacting the transaction price. The Company has included the following table regarding the Company’s non-interest income for the periods presented. Year Ended September 30, (In thousands) 2020 2019 Rental income $ 217 $ 243 Net gains on sale and call of investments 330 28 Net gains on sale of loans 116 37 Earnings on bank-owned life insurance 509 488 Non-interest income within the scope of other GAAP topics 1,172 796 ATM fees 10 6 Credit card fee income 21 24 DDA fee income 79 132 DDA service fees 76 75 Debit card fees 245 251 Other loan fee income 621 1,036 Other fee income 257 238 Other non-interest income 7 34 Non-interest income from contracts with customers $ 1,316 $ 1,796 Total Non-interest Income $ 2,488 $ 2,592 The decrease in other loan fee income during the fiscal year ended September 30, 2020 is primarily due to greater activity and recognition of net swap fees through the Bank’s commercial loan hedging program during fiscal 2019.

Earnings Per Share [Abstract]
Earnings Per Share	Note 5 – Earnings Per Share Basic earnings per common share is computed based on the weighted average number of shares outstanding reduced by unearned Employee Stock Ownership Plan (“ESOP”) shares. Diluted earnings per share is computed based on the weighted average number of shares outstanding and common stock equivalents (“CSEs”) that would arise from the exercise of dilutive securities reduced by unearned ESOP shares. For the fiscal year ended September 30, 2020, the Company issued stock options to purchase 7,000 shares of common stock, as well as 22,211 restricted shares, which are considered CSEs. issued stock options to purchase 7,000 shares of common stock, as well as 12,674 restricted shares, which are considered CSEs. The following table sets forth the composition of the weighted average shares (denominator) used in the earnings per share computations.

Employee Stock Ownership Plan E S O P Shares In E S O P [Abstract]
Employee Stock Ownership Plan	Note 6 – Employee Stock Ownership Plan The Company established an ESOP for substantially all of its full-time employees. As of September 30, 2020, the current ESOP trustee is Pentegra. Shares of the Company’s common stock purchased by the ESOP are held until released for allocation to participants. Shares released are allocated to each eligible participant based on the ratio of each such participant’s base compensation to the total base compensation of all eligible plan participants. As the unearned shares are committed to be released and allocated among participants, the Company recognizes compensation expense equal to the fair value of the ESOP shares during the periods in which they become committed to be released. To the extent that the fair value of the ESOP shares released differs from the cost of such shares, the difference is charged or credited to additional paid-in capital. During the period from May 20, 2008 to September 30, 2008, the ESOP purchased 241,178 shares of common stock for approximately $2.6 million, at an average price of $10.86 per share, which was funded by a loan from Malvern Federal Bancorp, Inc. (the Company’s predecessor). The ESOP loan is being repaid principally from the Bank’s contributions to the ESOP. The loan, which bears an interest rate of 5 percent, is being repaid in quarterly installments through 2026. Shares are released to participants proportionately as the loan is repaid. During each of the years ended September 30, 2020 and 2019, there were 14,400 shares committed to be released. At September 30, 2020, there were 85,965 unallocated shares and 173,253 allocated shares held by the ESOP. The unallocated shares had an aggregate fair value of approximately $1.0 million at September 30, 2020.

Investments Debt And Equity Securities [Abstract]
Investment Securities	Note 7 - Investment Securities The Company’s investment securities are classified as available-for-sale or held-to-maturity at September 30, 2020 and 2019. Investment securities available-for-sale are reported at fair value with unrealized gains or losses included in equity, net of tax. Accordingly, the carrying value of such securities reflects their fair value at the balance sheet date. Fair value is based upon either quoted market prices, or in certain cases where there is limited activity in the market for a particular instrument, assumptions are made to determine their fair value. Transfers of debt securities from the available-for-sale category to the held-to-maturity category are made at fair value at the date of transfer. The unrealized holding gain or loss at the date of transfer remains in accumulated other comprehensive income and in the carrying value of the held-to-maturity investment security. Premiums or discounts on investment securities are amortized or accreted using the effective interest method over the life of the security as an adjustment of yield. Unrealized holding gains or losses that remain in accumulated other comprehensive income are amortized or accreted over the remaining life of the security as an adjustment of yield, offsetting the related amortization of the premium or accretion of the discount. The following tables present information related to the Company’s investment securities at September 30, 2020 and 2019.

Given the historic low interest rates prevalent in the market, it is necessary for the Company to protect itself from interest rate exposure. Securities that once appeared to be sound investments can, after changes in the market, become securities that the Company has the flexibility to sell to avoid losses and mismatches of interest-earning assets and interest-bearing liabilities at a later time. The following tables indicate gross unrealized losses not recognized in income and fair value, aggregated by investment category and the length of time individual securities have been in a continuous unrealized loss position at September 30, 2020 and 2019.

These investment securities are comprised of securities that are rated investment grade by at least one bond credit rating service. Although the fair value will fluctuate as the market interest rates move, management believes that these fair values will recover as the underlying portfolios mature and are reinvested in market rate yielding investments. As of September 30, 2020, the Company held Investment securities having a carrying value of approximately $4.6 million and $6.4 million at September 30, 2020 and September 30, 2019, respectively, were pledged to secure public deposits. At September 30, 2020, no investment securities were pledged to secure hedges. Pledged investment securities having a carrying value of $4.0 million at September 30, 2019 were pledged to secure hedges. In addition, no investment securities were pledged to secure short-term borrowings of FHLB borrowings at September 30, 2020 and September 30, 2019. The following table presents information for investment securities at September 30, 2020, based on scheduled maturities.

The estimation of credit losses is not precise; the range of factors considered is wide and is significantly dependent upon management’s judgment, including the outlook and potential changes in the economic environment. At present, components of the commercial loan segments of the portfolio are new originations and the associated volumes continue to see increased growth. At the same time, historical loss levels have decreased as factors in assessing the portfolio. Any unallocated portion of the allowance reflects management’s estimate of probable inherent but undetected losses within the portfolio due to uncertainties in economic conditions, delays in obtaining information, including unfavorable information about a borrower’s financial condition, the difficulty in identifying triggering events that correlate perfectly to subsequent loss rates, and risk factors that have not yet manifested themselves in loss allocation factors. The following table presents impaired loans in portfolio by class, segregated by those for which a specific allowance was required and those for which a specific allowance was not necessary as of September 30, 2020 and 2019.

The increase in non-accrual loans was primarily due to additions of three commercial real estate loans totaling $17.6 million, four residential mortgage loans totaling $617,000, and two second mortgage consumer loans totaling $64,000. Interest income that would have been recognized on nonaccrual loans had they been current in accordance with their original terms was approximately $425,000 and $39,000 Management further monitors the performance and credit quality of the loan portfolio by analyzing the age of the portfolio as determined by whether a loan payment is “current,” that is, it is received from a borrower by the scheduled due date, or the length of time a scheduled payment is past due. The following table presents the classes of the loan portfolio summarized by the aging categories as of September 30, 2020 and 2019.

However, the Company generally only restructures loans by modifying the payment structure to require payments of interest only for a specified period or by reducing the actual interest rate. Once a loan becomes a TDR, it will continue to be reported as a TDR during the term of the restructure. The Company had twenty-six and twenty-four loans classified as TDRs with an aggregate outstanding balance of $21.7 million and $13.3 million at September 30, 2020 and 2019, respectively. At September 30, 2020, these loans were also classified as impaired. Eighteen of the TDR loans continue to perform under the restructured terms through September 30, 2020 and we continued to accrue interest on such loan through such date. The increase in TDRs at September 30, 2020 compared to September 30, 2019 was primarily due to one residential loan and two commercial real estate loans with an aggregate outstanding balance of $203,000, and $10.9 million respectively, moving to TDR status during fiscal 2020, partially offset by one residential mortgage loan paying off its balance of approximately $23,000. L oans that have been classified as TDRs have modified payment terms and in some cases interest rate from the original agreements and allowed the borrowers, who were experiencing financial difficulty, including but not limited to making interest only payments for a period of time in order to relieve some of their overall cash flow burden. Some loan modifications classified as TDRs may not ultimately result in the full collection of principal and interest, as modified, and result in potential incremental losses. These potential incremental losses have been factored into our overall estimate of the allowance for loan losses. The level of any defaults will likely be affected by future economic conditions. A default on a troubled debt restructured loan for purposes of this disclosure occurs when the borrower is 90 days past due or a foreclosure or repossession of the applicable collateral has occurred. Note 8 - Loans Receivable and Related Allowance for Loan Losses (Continued) TDRs may arise in which, due to financial difficulties experienced by the borrower, the Company obtains through physical possession one or more collateral assets in satisfaction of all or part of an existing credit. Once possession is obtained, the Company reclassifies the appropriate portion of the remaining balance of the credit from loans to OREO, which is included in the Consolidated Statements of Financial Condition. For any residential real estate property collateralizing a consumer mortgage loan, the Company is considered to possess the related collateral only if legal title is obtained upon completion of foreclosure, or the borrower conveys all interest in the residential real estate property to the Company through completion of a deed in lieu of foreclosure or similar legal agreement. Excluding OREO, the Company had $175,000 and $111,000 of residential real estate properties in the process of foreclosure at September 30, 2020 and 2019, respectively.

Under Section 4013 of the CARES Act, and separately based upon regulatory guidance promulgated by federal banking regulators (collectively “Interagency Statement”), qualifying short-term loan modifications resulting in payment deferrals that are attributable to the adverse impact of COVID-19, are not considered to be troubled debt restructurings (“TDRs”). As such, the applicable loans are reported as current with regard to payment status and continue to accrue interest during the payment deferral period.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives	Note 12 - Derivatives The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its debt funding and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the payment of future uncertain cash amounts, the value of which are determined by interest rates. The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income (loss) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. At September 30, 2020, such derivatives were used to hedge the variable cash flows associated with FHLB advances. Amounts reported in accumulated other comprehensive (loss) income related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s variable-rate debt. During the next twelve months, the Company estimates approximately $974,000 to be reclassified to earnings in interest expense. The Company is hedging its exposure to the variability in future cash flows for forecasted transactions over a maximum period of twenty months (excluding forecasted transactions related to the payment of variable interest on existing financial instruments). The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting interest rate swaps that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. These derivatives are not designated as hedges and are not speculative. Rather, these derivatives result from a service the Company provides to certain customers, which the Company implemented during the first quarter of fiscal 2019. As the interest rate swaps associated with this program do not meet the hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings.

At September 30, 2020 and 2019, the fair value of derivatives was in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements. There were no adjustments for nonperformance risk at September 30, 2020 and 2019. At September 30, 2020 and 2019, the Company has minimum collateral posting thresholds with certain of its derivative counterparties and has posted collateral of $12.9 million and $6.4 million, respectively, against its obligations under these agreements. If the Company had breached any of these provisions at September 30, 2020, it could have been required to settle its obligations under the agreements at the termination value and would have been required to pay any additional amounts due in excess of amounts previously posted as collateral with the respective counterparty.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 13 - Fair Value Measurements The Company follows FASB ASC Topic 820 “Fair Value Measurement,” to record fair value adjustments to certain assets and to determine fair value disclosures for the Company’s financial instruments. Investment and mortgage-backed securities available for sale are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on a nonrecurring basis, such as impaired loans, real estate owned and certain other assets. These nonrecurring fair value adjustments typically involve application of lower-of-cost-or-market accounting or write-downs of individual assets. The Company groups its assets at fair value in three levels, based on the markets in which the assets are traded and the reliability of the assumptions used to determine fair value. These levels are: Level 1—Valuation is based upon quoted prices for identical instruments traded in active markets. Level 2—Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3—Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect the Company’s own estimates of assumptions that market participants would use in pricing the asset. The Company bases its fair values on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. It is our policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements, in accordance with the fair value hierarchy. Fair value measurements for assets where there exists limited or no observable market data and, therefore, are based primarily upon the Company’s or other third-party’s estimates, are often calculated based on the characteristics of the asset, the economic and competitive environment and other factors. Therefore, the results cannot be determined with precision and may not be realized in an actual sale or immediate settlement of the asset. Additionally, there may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results of current or future valuations. The Company monitors and evaluates available data to perform fair value measurements on an ongoing basis and recognizes transfers among the levels of the fair value hierarchy as of the date event or a change in circumstances that affects the valuation method chosen. There were no changes in valuation technique or transfers between levels as of and for the years ended September 30, 2020 and 2019.

(3) Appraisals may be adjusted by management for qualitative factors such as time, changes in economic conditions and estimated liquidation expense At September 30, 2020 and 2019, the Company did not have any additions to our mortgage servicing assets. At September 30, 2020 the Company sold loans with servicing retained. At September 30, 2019, the Company only sold loans with servicing released. The following disclosure of the estimated fair value of financial instruments is made in accordance with the requirements of FASB ASC 825. The estimated fair value amounts have been determined by the Company using available market information and appropriate valuation methods. However, considerable judgment is necessarily required to interpret market data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company would realize in a current market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. FASB ASC 825 excludes certain financial instruments and all non-financial instruments from its disclosure requirements. Accordingly, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company. The fair value estimates presented herein are based on pertinent information available to management as of September 30, 2020 and 2019. Although management is not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since September 30, 2020 and 2019 and, therefore, current estimates of fair value may differ significantly from the amounts presented herein. The following assumptions were used to estimate the fair value of the Company’s financial instruments: Cash and Cash Equivalents —These assets are carried at historical cost. The carrying amount is a reasonable estimate of fair value because of the relatively short time between the origination of the instrument and its expected realization. Investment Securities — Investment and mortgage-backed securities available for sale (carried at fair value) are measured at fair value on a recurring basis. Fair value measurements for these securities are typically obtained from independent pricing services that we have engaged for this purpose. When available, we, or our independent pricing service, use quoted market prices to measure fair value. If market prices are not available, fair value measurement is based upon models that incorporate available trade, bid and other market information and for structured securities, cash flow and, when available, loan performance data. Because many fixed income securities do not trade on a daily basis, our independent pricing service’s applications apply available information through processes such as benchmark curves, benchmarking of like securities, sector groupings and matrix pricing to prepare evaluations. For Note 1 3 - Fair Value Measurements (Continued) each asset class, pricing applications and models are based on information from market sources and integrate relevant credit information. All of our securities available for sale are valued using either of the foregoing methodologies to determine fair value adjustments recorded to our financial statements. Loans Receivable —We do not record loans at fair value on a recurring basis. As such, valuation techniques discussed herein for loans are primarily for estimating fair value for FASB ASC 825 disclosure purposes. However, from time to time, we record nonrecurring fair value adjustments to loans to reflect partial write-downs for impairment or the full charge-off of the loan carrying value. The valuation of impaired loans is discussed below. The fair value estimate for FASB ASC 825 purposes differentiates loans based on their financial characteristics, such as product classification, loan category, pricing features and remaining maturity. Prepayment and credit loss estimates are evaluated by loan type and rate. The fair value of loans is estimated by discounting contractual cash flows using discount rates based on current industry pricing, adjusted for prepayment and credit loss estimates. Impaired Loans —Impaired loans are valued utilizing independent appraisals that rely upon quoted market prices for similar assets in active markets. These appraisals include adjustments to comparable assets based on the appraisers’ market knowledge and experience. The appraisals are adjusted downward by management, as necessary, for changes in relevant valuation factors subsequent to the appraisal date and are considered level 3 inputs. Accrued Interest Receivable —This asset is carried at historical cost. The carrying amount is a reasonable estimate of fair value because of the relatively short time between the origination of the instrument and its expected realization. Restricted Stock —Although restricted stock is an equity interest in the Federal Reserve Bank, FHLB and ACBB , it is carried at cost because it does not have a readily determinable fair value as its ownership is restricted and it lacks a market. The estimated fair value approximates the carrying amount. Other Real Estate Owned —Assets acquired through foreclosure or deed in lieu of foreclosure are recorded at estimated fair value less estimated selling costs when acquired, thus establishing a new cost basis. Fair value is generally based on independent appraisals. These appraisals include adjustments to comparable assets based on the appraisers’ market knowledge and experience, and are considered level 3 inputs. When an asset is acquired, the excess of the loan balance over fair value, less estimated selling costs, is charged to the allowance for loan losses. If the estimated fair value of the asset declines, a write-down is recorded through expense. The valuation of foreclosed assets is subjective in nature and may be adjusted in the future because of, among other factors, changes in the economic conditions. Deposits —Deposit liabilities are carried at cost. As such, valuation techniques discussed herein for deposits are primarily for estimating fair value for FASB ASC 825 disclosure purposes. The fair value of deposits is discounted based on rates available for time deposits of similar maturities. Fair value approximates book value for Savings accounts, Checking and NOW accounts, and Money Market accounts. Borrowings —Advances from the FHLB are carried at amortized cost. However, we are required to estimate the fair value of long-term debt under FASB ASC 825. The fair value is based on the contractual cash flows discounted using rates currently offered for new notes with similar remaining maturities. Subordinated Debt —The calculation of fair value in level 2 is based on observable market values where available. Note 13 - Fair Value Measurements (Continued) Derivatives — The fair value of derivatives are based on valuation models using observable market data as of the measurement date (level 2). Our derivatives are traded in an over-the-counter market where quoted market prices are not always available. Therefore, the fair values of derivatives are determined using quantitative models that utilize multiple market inputs. The inputs will vary based on the type of derivative, but could include interest rates, prices and indices to generate continuous yield or pricing curves, prepayment rate, and volatility factors to value the position. The majority of market inputs is actively quoted and can be validated through external sources, including brokers, market transactions and third-party pricing services . Accrued Interest Payable —This liability is carried at historical cost. The carrying amount is a reasonable estimate of fair value because of the relatively short time between the origination of the instrument and its expected realization. Commitments to Extend Credit and Letters of Credit —The majority of the Company’s commitments to extend credit and letters of credit carry current market interest rates if converted to loans and are not included in the table below . Because commitments to extend credit and letters of credit are generally unassignable by either the Bank or the borrower, they only have value to the Company and the borrower. The estimated fair value approximates the recorded deferred fee amounts, which are not significant. Mortgage Servicing Rights —The fair value of mortgage servicing rights is based on observable market prices when available or the present value of expected future cash flows when not available. Assumptions, such as loan default rates, costs to service, and prepayment speeds significantly affect the estimate of future cash flows.

Income Tax Disclosure [Abstract]
Income Taxes	Note 14 - Income Taxes In accordance with ASC Topic 740, the Company evaluates on a quarterly basis, all evidence, both positive and negative, to determine whether, based on the weight of that evidence, a valuation allowance for DTAs is needed. In conducting this evaluation, management explores all possible sources of taxable income available under existing tax laws to realize the net DTA beginning with the most objectively verifiable evidence first, including available carry back claims and viable tax planning strategies. If needed, management will look to future taxable income as a potential source. Management reviews the Company’s current financial position and its results of operations for the current and preceding years. That historical information is supplemented by all currently available information about future years. The Company understands that projections about future performance are subjective. Deferred income taxes at September 30, 2020 and 2019 were as follows: September 30, 2020 2019 (In thousands) DTAs: Allowance for loan losses $ 2,855 $ 2,431 Non-accrual interest 29 84 Supplement Employer Retirement Plan 193 216 Federal and State net operating loss — 56 Unrealized loss on investments available-for-sale 296 158 Depreciation 36 — Lease liability 656 — Other 88 45 Total DTAs 4,153 2,990 Valuation allowance for DTAs — — Total DTAs, Net of Valuation Allowance $ 4,153 $ 2,990 DTLs: Unrealized gain on derivatives — — Mortgage servicing rights (27 ) (46 ) Right of use asset (648 ) 0 Depreciation — (87 ) Other (2 ) (17 ) Total DTLs (677 ) (150 ) DTAs, Net $ 3,476 $ 2,840 Of these DTAs, the carryforward periods for certain tax attributes are as follows: • The Company has recorded state net operating loss carryforwards of approximately $12,000 and $3.0 million as of September 30, 2020 and 2019, respectively. These net operating losses will begin to expire in 2033. Note 14 – Income Taxes (Continued) Income tax expense for the fiscal years ended September 30, 2020 and 2019 was comprised of the following: September 30, 2020 2019 (In thousands) Federal: Current $ 1,019 $ 1,579 Deferred (335 ) 570 684 2,149 State: Current 435 228 Deferred (162 ) 92 273 320 Total income tax expense $ 957 $ 2,469 A reconciliation from the expected federal income tax expense computed at the statutory federal income tax rate to the actual income tax expense included in the consolidated statements of income for the fiscal years ended September 30, 2020 and 2019: September 30, 2020 2019 (In thousands) Tax at statutory rate $ 957 21.0 % $ 2,478 21.0 % Adjustments resulting from: State tax, net of federal benefit 216 4.7 252 2.1 Tax-exempt interest (59 ) (1.3 ) (53 ) (0.4 ) Earnings on bank-owned life insurance (107 ) (2.3 ) (103 ) (0.9 ) Other (50 ) (1.1 ) (105 ) (0.9 ) Total $ 957 21.0 % $ 2,469 20.9 % It is the Company’s policy to provide for uncertain tax positions and the related interest and penalties based upon management’s assessment of whether a tax benefit is more like than not to be sustained upon examination by tax authorities. As of September 30, 2020 and 2019, there were no material uncertain tax positions related to federal and state income tax matters. The Company is currently open to audit under the statute of limitation by the Internal Revenue Service and state taxing authorities for the years ended September 30, 2017 to September 30, 2020. The Small Business Job Protection Act of 1996 provides for the repeal of the tax bad debt deduction computed under the percentage-of-taxable-income method. Upon repeal, the Company was required to recapture into income, over a six-year period, the portion of its tax bad debt reserves that exceeds its base year reserves (i.e., tax reserves for tax years beginning before 1988). The base year tax reserves, which may be subject to recapture if the Company ceases to qualify as a bank for federal income tax purposes, are restricted with respect to certain distributions and have been treated as a permanent tax difference.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 16 - Commitments and Contingencies The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, unused lines of credit and standby letters of credit. Such commitments involve, to varying degrees, elements of credit, and interest rate risk in excess of the amount recognized in the statements of financial condition. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Letters of credit are conditional commitments issued by the Company guaranteeing payments of drafts in accordance with the terms of the letter of credit agreements. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Collateral may be required to support letters of credit based upon management’s evaluation of the creditworthiness of each customer. The credit risk involved in issuing letters of credit is substantially the same as that involved in extending loan facilities to customers. Most letters of credit expire within one year. At September 30, 2020 and 2019, the uncollateralized portion of the letters of credit extended by the Company was approximately $9.1 million and $11.6 million, respectively. The current amount of the liability for guarantees under letters of credit was not material as of September 30, 2020 or 2019. Note 16 – Commitments and Contingencies (Continued) At September 30, 2020 and 2019, the following financial instruments were outstanding whose contract amounts represent credit risk: September 30, 2020 2019 (In thousands) Commitments to extend credit: Future loan commitments $ 7,687 $ 40,976 Undisbursed construction loans 24,551 27,645 Undisbursed home equity lines of credit 24,751 21,447 Undisbursed commercial lines of credit 22,918 27,782 Undisbursed commercial unsecured lines of credit 58,445 60,382 Overdraft protection lines 1,362 1,363 Standby letters of credit 9,074 11,589 Total Commitments $ 148,788 $ 191,184 Commitments to extend credit 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. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation. Collateral held varies but generally includes personal or commercial real estate. Unfunded commitments under commercial lines of credit are collateralized except for the overdraft protection lines of credit and commercial unsecured lines of credit. The amount of collateral obtained is based on management’s credit evaluation, and generally includes personal or commercial real estate. Various legal claims arise from time to time in the normal course of business which, in the opinion of management, will have no material effect on the Company’s consolidated financial statements.

Regulatory Matters Disclosure [Abstract]
Regulatory Matters	Note 17 - Regulatory Matters Shareholders’ Equity On March 14, 2019, the Company’s Board of Directors approved a stock repurchase plan, under which the Company is authorized to repurchase up to 194,516 shares, or approximately 2.5 percent of the Company’s current outstanding common stock. On February 28, 2020, the Company’s Board of Directors extended the timeframe for its current stock repurchase program from March 31, 2020 to December 31, 2020. This repurchase authority may be exercised from time to time and in such amounts as market conditions warrant. The repurchases may be made on the open market, in block trades or otherwise. The program may be suspended or discontinued at any time. During the fiscal year ended September 30, 2020, the Company purchased 177,653 shares of its common stock in the open market under the repurchase plan at an average cost of $14.23 per share. As of September 30, 2020, no shares remain available for issuance under the repurchase plan. Regulatory Capital Requirements 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 regulatory accounting practices. The Bank’s capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk-weightings and other factors.

As of September 30, 2020, the Company’s and the Bank’s current capital levels exceed the required capital amounts to be considered “well capitalized” and we believe they also meet the fully-phased in minimum capital requirements, including the related capital conservation buffers, as required by the Basel III capital rules.

Equity Based Incentive Compensation Plan	Note 19 – Equity Based Incentive Compensation Plan The Company maintains the Malvern Bancorp, Inc. 2014 Long-Term Incentive Compensation Plan (the “2014 Plan”), which permits the grant of long-term incentive and other stock and cash awards. The purpose of the 2014 Plan is to promote the success of the Company and the Bank by providing incentives to officers, employees and directors of the Company and the Bank that will link their personal interests to the financial success of the Company and to growth in shareholder value. The maximum total number of shares of the Company’s common stock available for grants under the 2014 Plan is 400,000. As of September 30, 2020, there were 318,651 remaining shares available for future grants. Restricted stock and option awards granted during fiscal 2020 vest in 20 percent increments beginning on the one- year Note 1 9 - Equity Based Incentive Compensation Plan (Continued) All awards are issued at fair value of the underlying shares at the grant date. The Company expenses the cost of the awards, which is determined to be the fair market value of the awards at the date of grant. During fiscal 2020 and 2019, stock options covering a total 7,000 and 7,000 During fiscal 2020, 23,821 shares of restricted stock were awarded and 1,610 of those shares were forfeited. During fiscal 2019, 12,674 shares of restricted stock were awarded and 1,772 of those shares were forfeited. Stock-based compensation expense for the cost of the awards granted is based on the grant-date fair value. For stock option awards, the fair value is estimated at the date of grant using the Black-Scholes option-pricing model. This model requires the input of highly subjective assumptions, changes to which can materially affect the fair value estimate. Additionally, there may be other factors that would otherwise have a significant effect on the value of employee stock options granted but are not considered by the model. Accordingly, while management believes that the Black-Scholes option-pricing model provides a reasonable estimate of fair value, the model does not necessarily provide the best single measure of fair value for the Company’s employee stock options. Stock Options The assumptions used in determining the fair value of stock option grants for the year ended September 30, 2020 are as follows: Weighted average fair value of awards $ 4.72 Risk-free rate 1.22 % Dividend yield — % Volatility 19.86 % Expected life 6.5 years The assumptions used in determining the fair value of stock option grants for the year ended September 30, 2019 are as follows: Weighted average fair value of awards $ 5.72 Risk-free rate 2.50 % Dividend yield — % Volatility 20.39 % Expected life 6.5 years The following is a summary of currently outstanding options at September 30, 2020: Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term (In Years) Aggregate Intrinsic Value Outstanding, beginning of year 18,830 $ 22.05 $ 21,350 Granted 7,000 $ 20.28 $ — Exercised — $ — $ — Forfeited/cancelled/expired — $ — $ — Outstanding, end of year 25,830 $ 21.57 7.819 $ — Exercisable at end of year 8,140 $ 21.50 6.794 $ — Nonvested at end of year 17,690 $ 21.60 Note 1 9 - Equity Based Incentive Compensation Plan  (Continued) The following is a summary of currently outstanding options at September 30, 2019: Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term (In Years) Aggregate Intrinsic Value Outstanding, beginning of year 15,996 $ 22.34 $ 41,490 Granted 7,000 $ 20.90 — Exercised — — — Forfeited/cancelled/expired (4,166 ) $ 21.24 $ 4,120 Outstanding, end of year 18,830 $ 22.05 8.231 $ 21,350 Exercisable at end of year 4,370 $ 21.02 7.421 $ 8,632 Nonvested at end of year 14,460 $ 22.36 As of September 30, 2020, there was $84,000 of total unrecognized compensation cost related to non-vested options under the Plan.

Debt Disclosure [Abstract]
Subordinated Debt	Note 20 – Subordinated Debt On February 7, 2017, the Company issued $25.0 million in aggregate principal amount of its 6.125 percent fixed-to-floating rate subordinated notes due 2027 (the “Notes”). The Notes have a stated maturity of February 15, 2027, are redeemable, in whole or in part, on or after February 15, 2022, and at any time upon the occurrences of certain events. The Notes bear interest at a fixed rate of 6.125 percent per year, from and including February 7, 2017 to, but excluding February 15, 2022. From and including February 15, 2022 to the maturity date or earlier redemption date, the interest rate will reset quarterly at a variable rate equal to the then current 3-month LIBOR plus 414.5 basis points. The Notes were structured to qualify as Tier 2 capital for regulatory purposes. The Company’s net subordinated debt totaled $24.8 million ($737,000 represent original debt issuance costs) at September 30, 2020. The Company may not redeem the Notes prior to February 15, 2022, except that the Company may redeem the Notes at any time, at its option, in whole but not in part, subject to obtaining any required regulatory approvals, if (i) a change or prospective change in law occurs that could prevent the Company from deducting interest payable on the Notes for U.S. federal income tax purposes, (ii) a subsequent event occurs that precludes the Notes from being recognized as Tier 2 capital for regulatory capital purposes, or (iii) the Company is required to register as an investment company under the Investment Company Act of 1940, as amended, in each case, at a redemption price equal to 100 percent of the principal amount of the Notes plus any accrued and unpaid interest through, but excluding, the redemption date.

Subsequent Events [Abstract]
Subsequent Event	Note 23 – Subsequent Event The Company started accepting and processing applications for loans under the PPP in early April 2020, when the program was officially launched by the SBA and Treasury Department under the CARES Act. As of September 30, 2020, the Company obtained approval from the SBA for 255 PPP loans totaling $20.8 million for both existing and new customers, with an average loan size of approximately $81,000. Recognizing the significance of operational risk that this portfolio poses, and the continued complexity and uncertainty surrounding evolving regulatory pronouncements regarding various aspects of the PPP, management reviewed several options for continued servicing of the PPP loan portfolio through forgiveness and beyond. After thoughtful consideration, management decided that it is in the best interests of both the Bank and our PPP borrowers that the loans be serviced by an organization that has the servicing infrastructure in place to support the significant volume and short timeframe involved in the complex and evolving PPP forgiveness process. In that regard, in mid December the Bank sold substantially all of its PPP loans to a seasoned and experienced non-bank lender and servicer of SBA loans. In connection with the sale, the Company recognized a $202,000 gross gain on the sale of approximately $19.7 million of PPP loans which was recorded as non-interest income.

Accounting Policies [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The consolidated financial statements at and for the years ended September 30, 2020 and 2019 include the accounts of Malvern Bancorp, Inc. and its subsidiaries. All significant intercompany transactions and balances have been eliminated.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) 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 consolidated financial statements and the reported amounts of income and expenses 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 loan losses and the valuation of DTAs.
Significant Group Concentrations of Credit Risk	Significant Group Concentrations of Credit Risk Most of the Company’s activities are with customers located within Chester County, Pennsylvania and Morris County, New Jersey. Our lending efforts are also focused in Bucks County, Montgomery County and Delaware County, which are also in southeastern Pennsylvania, New Jersey and the New York metropolitan marketplace. Note 7 discusses the types of investment securities that the Company invests in. Note 8 discusses the types of lending that the Company engages in. The Company does not have any significant concentrations to any one industry or customer. Although the Company has a diversified portfolio, its debtor’s ability to honor their contracts is influenced by, among other factors, the region’s economy.
Operating, Accounting and Reporting Considerations related to COVID-19	Operating, Accounting and Reporting Considerations related to COVID-19 The COVID-19 pandemic has negatively impacted the global economy. In response to the crisis, the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act was passed by Congress and signed into law on March 27, 2020. The CARES Act provides an estimated $2.2 trillion to fight the COVID-19 pandemic and stimulate the economy by supporting individuals and businesses through loans, grants, tax changes, and other types of relief. Under Section 4013 of the CARES Act, and based upon regulatory guidance promulgated by federal banking regulators, qualifying short-term loan modifications resulting in payment deferrals that are attributable to the adverse impact of COVID-19, are not considered to be troubled debt restructurings (“TDRs”). • Accounting for Loan Modifications – The CARES Act provides that a financial institution may elect to suspend (1) the requirements under GAAP for certain loan modifications that would otherwise be categorized as a troubled debt restructure (“TDR”) and (2) any determination that such loan modifications would be considered a TDR, including the related impairment for accounting purposes. The suspension is applicable for the term of the loan modification that occurs during the applicable period for a loan that was not more than 30 days past due as of December 31, 2019. The suspension is not applicable to any adverse impact on the credit of a borrower that is not related to the pandemic. • Paycheck Protection Program – The CARES Act established the Paycheck Protection Program (“PPP”), an expansion of the Small Business Administration’s 7(a) loan program and the Economic Injury Disaster Loan Program (“EIDL”), administrated directly by the Small Business Administration (“SBA”). • Mortgage Forbearance – Under the CARES Act, through the earlier of December 31, 2020, mortgage customers experiencing financial hardship due to COVID-19 may request forbearance on the loan for up to 30 days, with up to two additional 30-day periods at the borrower’s request. Also in response to the COVID-19 pandemic, the Board of Governors of the Federal Reserve System (“FRB”), the Federal Deposit Insurance Corporation (“FDIC”), the National Credit Union Administration (“NCUA”), the Office of the Comptroller of the Currency (“OCC”), and the Consumer Financial Protection Bureau (“CFPB”), in consultation with the state financial regulators (collectively, the “agencies”) issued a joint interagency statement (issued March 22, 2020; revised statement issued April 7, 2020). Some of the provisions applicable to the Company include, but are not limited to: Note 2 - Summary of Significant Accounting Policies (Continued) • Accounting for Loan Modifications – Loan modifications that do not meet the conditions of the CARES Act may still qualify as a modification that does not need to be accounted for as a TDR. The agencies confirmed with FASB staff that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who are current prior to any relief are not TDRs. This includes short-term (e.g., six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or insignificant delays in payments. Loan modifications were made in accordance with Section 4013 of the CARES Act and the Interagency Statement on Loan Modifications and Reporting for Financial Institutions working with customers affected by COVID-19 and therefore were not classified as TDRs. • Past Due Reporting – With regard to loans not otherwise reportable as past due, financial institutions are not expected to designate loans with deferrals granted due to COVID-19 as past due because of the deferral. A loan’s payment date is governed by the due date stipulated in the legal agreements. If a financial institution agrees to a payment deferral, these loans would not be considered past due during the period of the deferral. • Nonaccrual Status and Charge-offs – During short-term COVID-19 modifications, these loans generally should not be reported as nonaccrual or as classified.
Risks and Uncertainties	Risks and Uncertainties On March 11, 2020, the World Health Organization declared the outbreak of COVID-19 a global pandemic. The COVID-19 pandemic has adversely affected, and may continue to adversely affect local, national and global economic activity. Actions taken to help mitigate the spread of COVID-19 include restrictions on travel, localized quarantines, and government-mandated closures of certain businesses. The spread of the outbreak has caused significant disruptions to the U.S. economy and has disrupted banking and other financial activity in the areas in which the Company operates. On March 3, 2020, the Federal Open Market Committee reduced the targeted federal funds interest rate range by 50 basis points to 1.00 percent to 1.25 percent. This range was further reduced to 0 percent to 0.25 percent on March 16, 2020. On March 27, 2020, the CARES Act was enacted to, among other provisions, provide emergency assistance for individuals, families and businesses affected by the COVID-19 pandemic. These reductions in interest rates and other effects of the COVID-19 pandemic may materially and adversely affect the Company's financial condition and results of operations in future periods. It is unknown how long the adverse conditions associated with the COVID-19 pandemic will last and what the complete financial effect will be to the Company. It is possible that estimates made in the financial statements could be materially and adversely impacted as a result of these conditions, including estimates regarding expected credit losses on loans receivable, and other-than-temporary impairment of investment securities.
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from depository institutions and interest-bearing deposits. The Company maintains cash deposits in other depository institutions that occasionally exceed the amount of deposit insurance available. Management periodically assesses the financial condition of these institutions and believes that the risk of any possible credit loss is minimal. The Company is required to maintain average reserve balances in vault cash with the Federal Reserve Bank based upon outstanding balances of deposit transaction accounts. Based upon the Company’s outstanding transaction deposit balances, the Bank maintained a deposit account with the Federal Reserve Bank of Philadelphia in the amount of zero at September 30, 2020 and 2019.
Investment Securities	Investment Securities Held-to-maturity (“HTM”) are securities that includes debt securities that the Company has the positive intent and the ability to hold to maturity. These securities are reported at amortized cost and adjusted for unamortized Note 2 - Summary of Significant Accounting Policies (Continued) premiums and discounts. Securities held for trading are securities that are bought and held principally for the purpose of selling in the near term; these securities are reported at fair value, with unrealized gains and losses reported in current earnings. At September 30, 2020 and 2019, the Company had no investment securities classified as trading. Debt securities that will be held for indefinite periods of time and equity securities, including securities that may be sold in response to changes in market interest or prepayment rates, needs for liquidity and changes in the availability of and the yield of alternative investments, are classified as available for sale. Realized gains and losses are recorded on the trade date and are determined using the specific identification method. Securities held as available for sale are reported at fair value, with unrealized gains and losses, net of tax, reported as a component of accumulated other comprehensive income (“AOCI”). Management determines the appropriate classification of investment securities at the time of purchase. Securities are evaluated on a quarterly basis, and more frequently when market conditions warrant such an evaluation, to determine whether declines in their value are other-than-temporary. To determine whether a loss in value is other-than-temporary, management utilizes criteria such as the reasons underlying the decline, the magnitude and duration of the decline and whether or not management intends to sell or expects that it is more likely than not that it will be required to sell the security prior to an anticipated recovery of the fair value. The term “other-than-temporary” is not intended to indicate that the decline is permanent, but indicates that the prospects for a near-term recovery of value is not necessarily favorable, or that there is a lack of evidence to support a realizable value equal to or greater than the carrying value of the investment. Once a decline in value for a debt security is determined to be other-than-temporary, the other-than-temporary impairment is separated into (a) the amount of the total other-than-temporary impairment related to a decrease in cash flows expected to be collected from the debt security (the credit loss) and (b) the amount of the total other-than-temporary impairment related to all other factors. The amount of the total other-than-temporary impairment related to the credit loss is recognized in earnings. The amount of the total other-than-temporary impairment related to all other factors is recognized in other comprehensive income.
Loans Receivable	Loans Receivable The Company, through the Bank, grants mortgage, construction, commercial and consumer loans to customers. Substantially all of our loans are to individuals, businesses and real estate developers in Chester County, Pennsylvania and neighboring areas in southern Pennsylvania, New Jersey and the New York metropolitan marketplace, Delaware and Florida markets. The ability of the Company’s debtors to honor their contracts is dependent upon, among other factors, the real estate and general economic conditions in this area. Loans receivable that management has the intent and ability to hold until maturity or payoff are stated at their outstanding unpaid principal balances, net of an allowance for loan losses and any deferred fees and costs. Interest income is accrued on the unpaid principal balance. Loan origination fees and costs are deferred and recognized as an adjustment of the yield (interest income) of the related loans using the interest method. The Company is amortizing these amounts over the contractual lives of the loans. The loans receivable portfolio is segmented into residential loans, construction and development loans, commercial loans and consumer loans. The residential loan segment has one class, one- to four-family first lien residential mortgage loans. The construction and development loan segment consists of the following classes: residential and commercial and land loans. Residential construction loans are made for the acquisition of and/or construction on a lot or lots on which a residential dwelling is to be built. Commercial construction loans are made for the purpose of acquiring, developing and constructing a commercial structure. The commercial loan segment consists of the following classes: commercial real estate loans, multi-family real estate loans, and other commercial loans, which are also generally known as commercial and industrial loans or commercial business loans. The consumer loan segment consists of the following classes: home equity lines of credit, second mortgage loans and other consumer loans, primarily unsecured consumer lines of credit. For all classes of loans receivable, the accrual of interest is discontinued when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about further collection of principal or interest, even though the loan is currently performing. A loan may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan is placed on nonaccrual status, unpaid interest credited to income in the current year is reversed and unpaid interest accrued in prior years is charged against the allowance for loan losses. Interest received on nonaccrual loans, including impaired loans, generally is either applied against principal or reported as interest income, according to management’s judgment as to the Note 2 - Summary of Significant Accounting Policies (Continued) collectability of principal. Generally, loans are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time (generally six months) and the ultimate collectability of the total contractual principal and interest is no longer in doubt. The past due status of all classes of loans receivable is determined based on contractual due dates for loan payments. In addition to originating loans, the Company purchases consumer and mortgage loans from brokers in our market area. Such purchases are reviewed for compliance with our underwriting criteria before they are purchased, and are generally purchased without recourse to the seller. Premiums and discounts on purchased loans are amortized as adjustments to interest income using the effective yield method. Reserves for unfunded lending commitments represent management’s estimate of losses inherent in its unfunded loan commitments and is recorded in other liabilities on the consolidated statements of financial condition.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for credit losses consists of the allowance for loan losses. The allowance for loan losses represents management’s estimate of losses inherent in the loan portfolio as of the consolidated statement of financial condition date and is recorded as a reduction to loans. The allowance for loan losses (“ALLL”, “allowance”) is increased by the provision for loan losses and decreased by charge-offs, net of recoveries. Loans deemed to be uncollectible are charged against the allowance for loan losses, and subsequent recoveries, if any, are credited to the allowance. All, or part, of the principal balance of loans receivable are charged off to the allowance as soon as it is determined that the repayment or collateral recovery of all, or part, of the principal balance is highly unlikely. Non-residential consumer loans a The allowance for credit losses is maintained at a level considered adequate to provide for losses that can be reasonably estimated. Management performs a quarterly evaluation of the adequacy of the allowance. The allowance is based on the Company’s past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral, the composition of the loan portfolio, current economic conditions and other relevant factors. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant revision as more information becomes available. The allowance consists of specific, general and unallocated components. The specific component relates to loans that are classified as impaired. For loans that are classified as impaired, a specific reserve is recognized 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 pools of loans by loan class that are not considered impaired. These pools of loans are evaluated for loss exposure based upon historical loss rates for each of these classes of loans, as adjusted for qualitative factors. These qualitative risk factors include: 1. Lending policies and procedures, including underwriting standards and collection, charge-off, and recovery practices. 2. National, regional, and local economic and business conditions as well as the condition of various market segments, including the value of underlying collateral for collateral dependent loans. 3. The nature and volume of the loan portfolio and terms of loans. 4. The experience, ability, and depth of lending management and staff. 5. The volume and severity of past due, classified and nonaccrual loans as well as any other loan modifications. 6. The quality of the Company’s loan review system, and the degree of oversight by the Company’s Board of Directors. Note 2 - Summary of Significant Accounting Policies (Continued) 7. The existence and effect of any concentrations of credit and changes in the level of such concentrations. 8. Value of underlying collateral. 9. A single calculation figure which is subsequently applied to the loan portfolio by loan type (Commercial, Residential and Consumer) based upon the percent of each to total loans. It is derived from a review of a peer group consisting of ten banks with similar asset size within the same general geographic area of the Bank. The qualitative factors are applied to the historical loss rates for each class of loan. In addition, while not reported as a separate factor, changes in the value of underlying collateral (for regional property values) for collateral dependent loans is considered and addressed within the economic trends factor. A quarterly calculation is made adjusting the reserve allocation for each factor within a risk weighted range as it relates to each particular loan type, collateral type and risk rating within each segment. Data is gathered and evaluated through internal, regulatory, and government sources quarterly for each factor. An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. In addition, the allowance calculation methodology includes further segregation of loan classes into risk rating categories. The borrower’s overall financial condition, repayment sources, guarantors and value of collateral, if appropriate, are evaluated annually for commercial loans or when credit deficiencies arise, such as delinquent loan payments, for commercial and consumer loans. Credit quality risk ratings include categories of “pass,” “special mention,” “substandard” and “doubtful.” Assets classified as “Pass” are those protected by the current net worth and paying capacity of the obligor or by the value of the underlying collateral. Assets which do not currently expose the insured institution to sufficient risk to warrant classification as substandard or doubtful but possess certain identified weaknesses are required to be designated “special mention.” If uncorrected, the potential weaknesses may result in deterioration of the repayment prospects. An asset is considered “substandard” if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. “Substandard” assets include those characterized by the “distinct possibility” that the insured institution will sustain “some loss” if the deficiencies are not corrected. Assets classified as “doubtful” have all of the weaknesses inherent in those classified “substandard” with the added characteristic that the weaknesses present make “collection or liquidation in full,” on the basis of currently existing facts, conditions, and values, “highly questionable and improbable.” Residential Lending. Residential mortgage originations are secured primarily by properties located in the Company’s primary market area and surrounding areas. We currently originate fixed-rate, fully amortizing mortgage loans with maturities of 10 to 30 years. We also offer adjustable rate mortgage (“ARM”) loans where the interest rate either adjusts on an annual basis or is fixed for the initial one, three or seven years and then adjusts annually. We underwrite one- to four-family residential mortgage loans with loan-to-value ratios of up to 95 percent, provided that the borrower obtains private mortgage insurance on loans that exceed 80 percent of the appraised value or sales price, whichever is less, of the secured property. We also require that title insurance, hazard insurance and, if appropriate, flood insurance be maintained on all properties securing real estate loans. We require that a licensed appraiser from our list of approved appraisers perform and submit to us an appraisal on all properties secured by a first mortgage on one- to four-family first mortgage loans. In underwriting one- to four-family residential mortgage loans, the Company evaluates both the borrower’s ability to make monthly payments and the value of the property securing the loan. Most properties securing real estate loans made by the Company are appraised by independent fee appraisers reviewed and approved by the Bank’s third-party appraisal management companies. The Company generally requires borrowers to obtain an attorney’s title opinion or title insurance, and fire and property insurance (including flood insurance, if necessary) in an amount not less than the amount of the loan. Real estate loans originated by the Company generally contain a “due on sale” clause allowing the Company to declare the unpaid principal balance due and payable upon the sale of the security property. The Company has not engaged in sub-prime residential mortgage loan originations. Our single-family residential mortgage loans generally are underwritten on terms and documentation conforming to guidelines issued by The Federal Home Loan Mortgage Company, or Freddie Mac, and The Federal National Mortgage Association, or Fannie Mae. Note 2 - Summary of Significant Accounting Policies (Continued) Construction and Development Lending. We originate construction loans for residential and, to a lesser extent, commercial uses within our market area. We generally limit construction loans to builders and developers with whom we have an established relationship, or who are otherwise known to officers of the Bank. Our construction and development loans currently in the portfolio typically have variable rates of interest tied to the prime rate which improves the interest rate sensitivity of our loan portfolio. Construction and development loans generally are considered to involve a higher level of risk than one-to four-family residential lending, due to the concentration of principal in a limited number of loans and borrowers and the effect of economic conditions on developers, builders and projects. Additional risk is also associated with construction lending because of the inherent difficulty in estimating both a property’s value at completion and the estimated cost (including interest) to complete a project. The nature of these loans is such that they are more difficult to evaluate and monitor. In addition, speculative construction loans to a builder are not pre-sold and thus pose a greater potential risk than construction loans to individuals on their personal residences. In order to mitigate some of the risks inherent in construction lending, we inspect properties under construction, review construction progress prior to advancing funds, work with builders with whom we have established relationships, require annual updating of tax returns and other financial data of developers and obtain personal guarantees from the principals. Commercial Lending. Commercial and multi-family real estate loans generally present a higher level of risk than loans secured by one- to four-family residences. This greater risk is due to several factors, including the concentration of principal in a limited number of loans and borrowers, the effect of general economic conditions on income producing properties and the increased difficulty of evaluating and monitoring these types of loans. Furthermore, the repayment of loans secured by commercial and multi-family real estate is typically dependent upon the successful operation of the related real estate project. If the cash flow from the project is reduced (for example, if leases are not obtained or renewed, or a bankruptcy court modifies a lease term, or a major tenant is unable to fulfill its lease obligations), the borrower’s ability to repay the loan may be impaired. Most of the Company’s commercial business loans have been extended to finance local and regional businesses and include short-term loans to finance machinery and equipment purchases, inventory and accounts receivable. The commercial business loans which we originate may be either a revolving line of credit or for a fixed term of generally 10 years or less. Interest rates are adjustable, indexed to a published prime rate of interest, or fixed. Generally, equipment, machinery, real property or other corporate assets secure such loans. Personal guarantees from the business principals are generally obtained as additional collateral. Consumer Lending. The Company currently originates most of its consumer loans in its primary market area and surrounding areas. The Company originates consumer loans on both a direct and indirect basis. Consumer loans generally have higher interest rates and shorter terms than residential mortgage loans; however, they have additional credit risk due to the type of collateral securing the loan or in some case the absence of collateral. We are continuing to evaluate and monitor the credit conditions of our consumer loan borrowers and the real estate values of the properties securing our second mortgage loans as part of our on-going efforts to assess the overall credit quality of the portfolio in connection with our review of the allowance for loan losses. Consumer loans may entail greater credit risk than do residential mortgage loans, particularly in the case of consumer loans which are unsecured or are secured by rapidly depreciable assets, such as automobiles or recreational equipment. In such cases, any repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment of the outstanding loan balance as a result of the greater likelihood of damage, loss or depreciation. In addition, consumer loan collections are dependent on the borrower’s continuing financial stability, and thus are more likely to be affected by adverse personal circumstances. Furthermore, the application of various federal and state laws, including bankruptcy and insolvency laws, may limit the amount which can be recovered on such loans. Once all factor adjustments are applied, general reserve allocations for each segment are calculated, summarized and reported on the ALLL summary. ALLL final schedules, calculations and the resulting evaluation process are reviewed quarterly. In addition, Federal bank regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance and may require the Company to recognize additions to the allowance based on their judgments about information available to them at the time of their examination. Based on management’s comprehensive analysis of the loan portfolio, management believes the current level of the allowance for loan losses is adequate. Note 2 - Summary of Significant Accounting Policies (Continued) A loan is considered impaired when, based on current information and events, it is probable that the Company 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, cash flow, and the probability of collecting scheduled principal and interest payments when due. 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. A specific reserve is established for an impaired loan if its carrying value exceeds its estimated fair value. The estimated fair values of substantially all of the Company’s impaired loans are measured based on the estimated fair value of the loan’s collateral. For commercial loans secured by real estate, estimated fair values are determined primarily through third-party appraisals. When a real estate secured loan becomes impaired, a decision is made regarding whether an updated appraisal of the real estate is necessary. This decision is based on various considerations, including the age of the most recent appraisal, the loan-to-value ratio based on the original appraisal and the condition of the property. Appraised values are discounted to arrive at the estimated selling price of the collateral, which is considered to be the estimated fair value. The discounts also include estimated costs to sell the property. For commercial and industrial loans secured by non-real estate collateral, such as accounts receivable, inventory and equipment, estimated fair values are determined based on the borrower’s financial statements, inventory reports, accounts receivable aging or equipment appraisals or invoices. Indications of value from these sources are generally discounted based on the age of the financial information or the quality of the assets.
Troubled Debt Restructurings	Troubled Debt Restructurings Loans whose terms are modified are classified as TDRs if the Company grants such borrowers concessions and it is deemed that those borrowers are experiencing financial difficulty. Concessions granted under a troubled debt restructuring may be modified by means of extending the maturity date of the loan, reducing the interest rate on the loan to a rate which is below market, a combination of rate adjustments and maturity extensions, or by other means including covenant modifications, forbearances or other concessions. However, the Company generally only restructures loans by modifying the payment structure to interest only or by reducing the actual interest rate. We do not accrue interest on loans that were non-accrual prior to the TDR troubled debt restructurings . Management evaluates the ALLL with respect to TDRs under the same policy and guidelines as all other performing loans are evaluated with respect to the ALLL. In March 2020, various regulatory agencies, including the FRB and the FDIC issued an interagency statement on loan modifications and reporting for financial institutions working with customers affected by COVID-19. The interagency statement was effective immediately and impacted accounting for loan modifications. The agencies confirmed with the staff of the FASB that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief, are not to be considered TDRs. Provisions of the CARES Act largely mirrored the provisions of the interagency statement, providing that modified loans were not to be considered TDRs if they were performing at December 31, 2019 and other consideration set forth in the interagency statements were met. Borrowers considered current were those that are less than 30 days past due on their contractual payments at the time a modification program is implemented or at December 31, 2019.
Loan Servicing	Note 2 - Summary of Significant Accounting Policies (Continued) Loan Servicing Servicing assets are recognized as separate assets when rights are acquired through purchase or through sale of financial assets. For sales of mortgage loans, a portion of the cost of originating the loan is allocated to the servicing right based on relative fair value. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. Capitalized servicing rights are reported in other assets and are amortized into other expense in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets. Servicing assets are evaluated for impairment based upon the fair value of the rights as compared to amortized cost. Impairment is determined by stratifying rights into tranches based on predominant risk characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual tranche, to the extent that fair value is less than the capitalized amount for the tranche. If the Company later determines that all or a portion of the impairment no longer exists for a particular tranche, a reduction of the allowance may be recorded as an increase to income. The Company also sells loans in the secondary market with servicing released.
Other Real Estate Owned	Other Real Estate Owned Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value 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 the previously established carrying amount or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in other expenses from OREO.
Restricted Stock	Restricted Stock Restricted stock represents required investments in the common stock of a correspondent bank and is carried at cost. As of September 30, 2020 and 2019, restricted stock consists of the common stock of the Federal Reserve Bank, FHLB and Atlantic Community Bankers Bank (“ACBB”). Management’s evaluation and determination of whether these investments are impaired is based on their assessment of the ultimate recoverability of their cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of an investment’s cost is influenced by criteria such as (1) the significance of the decline in net assets of the Federal Reserve Bank, FHLB and ACBB as compared to the capital stock amount for the Federal Reserve Bank, FHLB and ACBB and the length of time this situation has persisted, (2) commitments by the Federal Reserve Bank, FHLB and ACBB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the Federal Reserve Bank, FHLB and ACBB, and (3) the impact of legislative and regulatory changes on institutions and, accordingly, on the customer base of the Federal Reserve Bank, FHLB and ACBB. During the years ended September 30, 2020 and 2019, there were net repurchases of restricted stock of $1.5 million and $2.6 million, respectively. Also, as of September 30, 2020 and 2019, the number of outstanding restricted shares was 122,177 and 137,148, respectively. There were approximately $631,000 and $627,000
Property and Equipment	Property and Equipment Property and equipment is carried at cost. Depreciation is computed using the straight-line and accelerated methods over estimated useful lives ranging from 3 to 39 years beginning when assets are placed in service. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any gain or loss is reflected in income for the period. The cost of maintenance and repairs is charged to income as incurred.
Transfers of Financial Assets	Note 2 - Summary of Significant Accounting Policies (Continued) 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. The Company accounts for certain participation interests in commercial loans receivable (loan participation agreements) sold as a sale of financial assets pursuant to ASC 860, Transfers and Servicing. Loan participation agreements that meet the sale criteria under ASC 860 are derecognized from the Consolidated Statement of Financial Condition at the time of transfer. If the transfer of loans subject to loan participation does not meet the sale criteria or participating interest criteria under ASC 860, the transfer is accounted for as a secured borrowing and the loan is not de-recognized and a participating liability is recorded in the Consolidated Statements of Financial Condition.
Bank-Owned Life Insurance	Bank-Owned Life Insurance The Company invests in bank owned life insurance (“BOLI”) as a source of funding for employee benefit expenses. BOLI involves the purchasing of life insurance by the Bank on a chosen group of employees. The Bank is the owner and beneficiary of the policies. This life insurance investment is carried at the cash surrender value of the underlying policies. Earnings from the increase in cash surrender value of the policies are included in other income on the statements of operations.
Employee Benefit Plans	Employee Benefit Plans The Bank’s 401(k) plan allows eligible participants to set aside a certain percentage of their salaries before taxes. The Company may elect to match employee contributions up to a specified percentage of their respective salaries in an amount determined annually by the Board of Directors. The Company’s matching contribution related to the plan resulted in expenses of $131,000 and $135,000 The Company also maintains an unfunded Supplemental Executive and a Director Retirement Plan (the “Plans”). The accrued amount for the Plans included in other liabilities was $784,000 and $875,000 at September 30, 2020 and 2019, respectively. Distributions from the Plan for each of the fiscal years 2020 and 2019 were approximately $94,000 and $100,000, respectively. The expense associated with the Plans was $4,000 for each of the years ended September 30, 2020 and 2019.
Derivatives and Hedging	Derivatives and Hedging The Company records cash flow hedges at the inception of the derivative contract based on the Company’s intentions and belief as to likely effectiveness as a hedge. The Company documents the strategy for entering into the transactions and the method of assessing ongoing effectiveness. Cash flow hedges represent a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability. For a cash flow hedge that is effective, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. The changes in the fair value of derivatives that are not highly effective in hedging the changes in fair value or expected cash flows of the hedged item are recognized immediately in current earnings. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in earnings, as noninterest income. Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in noninterest income. Cash flows on hedges are classified in the cash flow statement the same as the cash flows of the items being hedged. To determine fair value, the Company uses third party pricing models that incorporate assumptions about market conditions and risks that are current at the reporting date. The Company does not use derivative instruments for speculative purposes. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Company discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended. Note 2 - Summary of Significant Accounting Policies (Continued) When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as noninterest income. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in other comprehensive income are amortized into earnings over the same periods which the hedged transactions will affect earnings. The Company recognized $371,000 and $795,000 of net swap fees through the Bank’s commercial loan hedging program during fiscal 2020 and fiscal 2019, respectively.
Advertising Cost	Advertising Costs The Company follows the policy of charging the costs of advertising to expense as incurred. Advertising expense was $119,000 and $107,000
Income Taxes	Income Taxes DTAs and deferred tax liabilities (“DTLs”) are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. DTAs and DTLs are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on DTAs and DTLs of a change in tax rates is recognized in income in the period that includes the enactment date. These calculations are based on many complex factors including estimates of the timing of reversals of temporary differences, the interpretation of federal income tax laws and a determination of the differences between the tax and the financial reporting basis of assets and liabilities. Actual results could differ significantly from the estimates and interpretations used in determining the current and deferred income tax assets and liabilities. A valuation allowance is required to be recognized if it is “more likely than not” that a portion of the DTAs will not be realized. The Company’s policy is to evaluate the DTA on a quarterly basis and record a valuation allowance for our DTA if we do not have sufficient positive evidence indicating that it is more likely than not that some or all of the DTA will be realized. The Company’s policy is to account for interest and penalties as components of income tax expense.
Commitments and Contingencies	Commitments and Contingencies In the ordinary course of business, the Company has entered into off-balance sheet financial instruments consisting of commitments to extend credit and standby letters of credit. Such financial instruments are recorded in the statement of financial condition when they are funded.
Segment Information	Segment Information The Company has one reportable segment, “Community Banking.” All of the Company’s activities are interrelated, and each activity is dependent and assessed based on how each of the activities of the Company supports the others. For example, lending is dependent upon the ability of the Company to fund itself with deposits and other borrowings and manage interest rate and credit risk. Accordingly, all significant operating decisions are based upon analysis of the Company as one segment or unit.
Comprehensive Income	Comprehensive Income Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available for sale debt securities, are reported as a separate component of the shareholders’ equity section of the statement of financial condition, such items, along with net income, are components of comprehensive income. Note 2 - Summary of Significant Accounting Policies (Continued) For securities transferred from available for sale to held to maturity, the Company records the amortization and/or accretion of unrealized holding losses on such investment securities, in accumulated other comprehensive (loss) income. The Company also records changes in the fair value of interest rate derivatives used in its cash flow hedging activities, net of deferred income tax, in accumulated other comprehensive (loss) income.
Reclassifications	Reclassifications Certain reclassifications have been made to the previous year’s consolidated financial statements to conform to the current year’s presentation. These reclassifications had no effect on the Company’s results of operations.
Revenue Recognition	Revenue Recognition ASC 606, Revenue from Contracts with Customers The majority of our revenue-generating transactions are not subject to ASC 606, including revenue generated from financial instruments, such as our loans, investment securities, derivatives as well as revenue related to BOLI, sales of investment securities, rental income, and gain on sale of loans. Revenue-generating activities that are within the scope of ASC 606, which are presented in our consolidated statements of operations as components of other income include certain fees such as credit card fee income, DDA service and fee income, and debit card fees.
Loans Held-For-Sale	Loans Held-For-Sale Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value on the consolidated statements of financial condition. Gains and losses on loan sales (sales proceeds minus carrying value) are recorded in noninterest income, and direct loan origination costs and fees are deferred at origination of the loan and are recognized in other income upon sale of the loan. Servicing is retained at the Bank for loans sold in the secondary market and are placed as a mortgage servicing asset on the consolidated statement of financial condition.
Treasury Stock	Treasury stock The Company records common stock purchased for treasury at cost. At the date of subsequent reissue, the treasury stock account is reduced by the cost of such stock on the first-in, first-out basis.
Leases	Leases The Company accounts for its leases in accordance with FASB ASC Leases As a lessee, the Company enters into operating leases for certain bank branches, office space, and office equipment. The right-of-use assets and lease liabilities are initially recognized based on the net present value of the remaining lease payments, which include renewal options where management is reasonably certain they will be exercised. The net present value is determined using the incremental borrowing rate based on the FHLB
Recently Adopted Accounting Pronouncements and Recent Accounting Pronouncements Yet to Be Adopted	Note 2 - Summary of Significant Accounting Policies (Continued) Recently Adopted Accounting Pronouncements Leases . In February 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) to increase transparency and comparability among organizations recognizing lease assets and lease liabilities on the balance sheet. This ASU requires lessees to recognize a right-of-use (“ROU”) asset for its right to use the underlying asset and a lease liability for the corresponding lease obligation for leases with terms of more than twelve months. Accounting by lessors remains largely unchanged from current GAAP. This ASU also requires expanded quantitative and qualitative disclosures for both lessees and lessors. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, which provides entities with an additional (and optional) transition method in which the entity applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company has applied the new transition method upon adoption. In December 2018, the FASB issued ASU No. 2018-20, Leases (Topic 842): Narrow Scope Improvements for Lessors, which clarifies the treatment of sales taxes and other taxes collected from lessees, lessor costs paid directly by lessees, and recognition of variable payments for contracts with lease and non-lease components. In March 2019, the FASB issued ASU No. 2019-01, Leases (Topic 842): Codification Improvements, which aligned the new lease guidance with the existing guidance for fair value of the underlying asset by lessors that are not manufacturers or dealers. It also clarified an exemption for lessors and lessees from a certain interim disclosure requirement associated with adopting the board’s new lease accounting standard. The Company adopted the guidance in these ASUs on October 1, 2019 and will not restate comparative periods. As a result, the Company recorded ROU assets and related lease liabilities of $3.3 million at October 1, 2019. At September 30, 2020 the Company had ROU assets and related lease liabilities of $2.7 million. Recent Accounting Pronouncements Yet to Be Adopted Reference Rate Reform. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848) . The guidance allows for companies to: (1) account for certain contract modifications as a continuation of the existing contract without additional analysis; (2) continue hedge accounting when certain critical terms of a hedging relationship change and assess effectiveness in ways that disregard certain potential sources of ineffectiveness; and (3) make a one-time sale and/or transfer of certain debt securities from held-to-maturity to available-for-sale or trading. This ASU is available for adoption effective immediately, or as of January 1, 2020 or any date thereafter for the Company, and applies prospectively to contract modifications and hedging relationships. The one-time election to sell and/or transfer debt securities classified as held-to-maturity may be made at any time after March 12, 2020. The Company anticipates adopting this ASU and will continue to analyze the provisions of the ASU in connection with ongoing procedures to monitor the work of the Alternative Rates Committee of the FRB and Federal Reserve Bank of New York in identifying an alternative U.S. dollar reference interest rate. It is too early to predict a new rate index replacement, but we anticipate will be the Secured Overnight Financing Rate (“SOFR”). The adoption of this new requirement is not expected to have a material impact on the consolidated earnings, financial position or cash flows of the Company. Income Taxes. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740). This ASU identifies, evaluates, and improves areas of GAAP for which cost and complexity can be reduced while maintaining or improving the usefulness of the information provided to users of financial statements. The ASU is effective for fiscal years beginning after December 15, 2020, with early adoption permitted. The adoption of this new requirement is not expected to have a material impact on the consolidated earnings, financial position or cash flows of the Company. Credit Losses. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . This ASU requires an organization to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied currently will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. Organizations will continue to use judgment to determine which loss estimation method is appropriate for their circumstances. Additionally, this ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. In April 2019, the FASB issued ASU 2019-04, Codification Improvements , which provides guidance on accounting for credit losses on accrued interest receivable balances and guidance on including recoveries when estimating the allowance. In May 2019, the FASB issued ASU 2019-05, Targeted Transition Relief, which allows entities with an option to elect fair value for certain instruments upon adoption of Topic 326. This ASU will be effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted . The Bank has a software system in place to assist with the calculation of Current Expected Credit Losses (“CECL”). In November 2019, the FASB issued ASU No. 2019-10, Financial Instruments-Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842) making this ASU effective for interim and annual periods beginning after December 15, 2022. As such the Company would be required to implement the ASU on October 1, 2023. In November 2019, the FASB issued ASU No. 2019-11, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, which provides guidance on stakeholders’ specific issues about certain aspects of the amendments in ASU 2016-13. The Company formed a cross functional implementation team to review the requirements of ASU 2016-13 and contracted with a third-party provider to assist in the development and implementation of the revised credit loss methodology. The impacts on the consolidated earnings, financial position and cash flows of the Company upon adoption of this ASU are currently unknown.
