Accounting Policies [Abstract] |
Basis of Consolidated Financial Statement Presentation | Basis of consolidated financial statement presentation The consolidated financial statements include the accounts of the Company, the Bank and the Bank's wholly-owned or majority-owned subsidiaries, Carver Asset Corporation, CFSB Realty Corp., CCDC, and CFSB Credit Corp., which is currently inactive. All significant intercompany accounts and transactions have been eliminated in consolidation. The Company's subsidiary, Carver Statutory Trust I, is not consolidated with Carver Bancorp, Inc. for financial reporting purposes. Carver Statutory Trust I was formed in 2003 for the purpose of issuing $13 million aggregate liquidation amount of floating rate Capital Securities due September 17, 2033 (“Capital Securities”) and $0.4 million of common securities (which are the only voting securities of Carver Statutory Trust I), which are 100% owned by Carver Bancorp, Inc., and using the proceeds to acquire Junior Subordinated Debentures issued by Carver Bancorp, Inc. Carver Bancorp, Inc. has fully and unconditionally guaranteed the Capital Securities along with all obligations of Carver Statutory Trust I under the trust agreement relating to the Capital Securities. Variable interest entities (“VIEs”) are consolidated, as required, when Carver has controlling financial interest in these entities and is deemed to be the primary beneficiary. Carver is normally deemed to have a controlling financial interest and be the primary beneficiary if it has both (a) the power to direct activities of a VIE that most significantly impact the entities economic performance; and (b) the obligation to absorb losses of the entity that could benefit from the activities that could potentially be significant to the VIE. The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (GAAP). In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated statement of financial condition and revenues and expenses for the period then ended. Amounts subject to significant estimates and assumptions are items such as the allowance for loan losses, realization of deferred tax assets, assessment of other-than-temporary impairment of securities, and the fair value of financial instruments. While management uses available information to recognize losses on loans, future additions to the allowance for loan losses or future write-downs of real estate owned may be necessary based on changes in economic conditions in the areas where Carver Federal has extended mortgages and other credit instruments. Actual results could differ significantly from those assumptions. Current market conditions increase the risk and complexity of the judgments in these estimates. Recent Events The business climate continues to present significant challenges as banks continue to absorb heightened regulatory costs and compete for limited loan demand. Significant increases in food and energy prices resulted from swift increases in the rate of inflation. Additionally, the Federal Reserve has increased the federal funds rate at each of its meetings since March 2022, and while the rate was held steady at the most recent meeting in June 2023, it has indicated that it will likely increase again later this year. For Carver, the economic climate of New York City (“the City”), in particular, impacts our business as the City lags behind the rest of New York State and the nation both in restoring pandemic job losses and in rebounding to pre-pandemic levels of unemployment. The City's unemployment rate remains high at 5.4%, exceeding the national average, as employment in the arts and entertainment, food and hospitality sectors continue to remain below their pre-pandemic highs. In March 2023, the FDIC was appointed as receiver for Silicon Valley Bank and Signature Bank after they experienced runs on deposits and other liquidity constraints. At the time, Silicon Valley Bank and Signature Bank were the 16th and 29th largest banks in the United States, respectively, as measured by total assets as of December 31, 2022. Following the failures of Silicon Valley Bank and Signature Bank, on May 1, 2023, First Republic Bank was closed by the California Department of Financial Protection and Innovation, which appointed the FDIC as receiver. The closures of those banks led to industry-wide concerns related to liquidity, deposit outflows, unrealized securities losses and eroding confidence in the banking system. In response to these recent developments, the Company took a number of preemptive actions, which included proactive outreach to clients and steps to maximize its funding sources. As a result, the Company's liquidity position remains adequate. The impact of market volatility from the adverse developments in the banking industry along with continued high inflation and rising interest rates, will depend on future developments, which are highly uncertain and difficult to predict. The Company is closely monitoring its asset quality, liquidity, and capital positions, as well as the credit risk in its loan portfolio. Management is actively working to minimize the current and future impact of this unusual situation, and is continuing to make adjustments to operations where appropriate or necessary to mitigate risk. However, these factors and events may have negative effects on the business, financial condition, and results of operations of the Company and its customers.
Cash and Cash Equivalents | Cash and cash equivalents For the purpose of reporting cash flows, cash and cash equivalents include cash, amounts due from depository institutions and other short-term instruments with an original maturity of three months or less. The amounts due from depository institutions include an interest-bearing account held at the Federal Reserve Bank where any additional cash reserve required on demand deposits would be maintained. Currently, this reserve requirement is zero since the Bank's vault cash satisfies cash reserve requirements for deposits.
Investment Securities | Investment Securities When purchased, debt securities are designated as either investment securities held-to-maturity, available-for-sale or trading. Securities are classified as held-to-maturity and carried at amortized cost only if the Bank has a positive intent and ability to hold such securities to maturity. Securities held-to-maturity are carried at cost, adjusted for the amortization of premiums and the accretion of discounts using the level-yield method over the remaining period until maturity. If not classified as held-to-maturity or trading, securities are classified as available-for-sale based upon management's ability to sell in response to actual or anticipated changes in interest rates, resulting prepayment risk or any other factors. Available-for-sale securities are reported at fair value. Estimated fair values of securities are based on either published or security dealers' market value if available. If quoted or dealer prices are not available, fair value is estimated using quoted or dealer prices for similar securities. Securities that are bought and held principally for the purpose of selling them in the near term are classified as trading securities and are reported at fair value with unrealized gains and losses included in earnings. The Company conducts periodic reviews to identify and evaluate each investment that has an unrealized holding loss. Unrealized holding gains or losses for securities available-for-sale are excluded from earnings and reported net of deferred income taxes in accumulated other comprehensive loss, a component of Stockholders' Equity. The amount of an other-than-temporary impairment when there are credit and non-credit losses on a debt security that management does not intend to sell, and for which it is more likely than not that the Bank will not be required to sell the security prior to the recovery of the non-credit impairment, the portion of the total impairment that is attributable to the credit loss would be recognized in earnings. The remaining difference between the debt security's amortized cost basis and its fair value would be included in other comprehensive income (loss). There were no other-than-temporary impairment charges recorded during the fiscal year ended March 31, 2023. Gains or losses on sales of securities of all classifications are recognized based on the specific identification method.
Loans Held-for-Sale | Loans Held-for-Sale Loans are only transferred to held-for-sale classification upon the determination by Carver to sell a loan. Held-for-sale loans are carried at the lower of cost or fair value. The initial charge-off, if any is required, will be taken upon the transfer to held-for-sale and absorbed through Carver's loan loss reserve. Subsequent changes in fair value are recognized in earnings as a valuation allowance. The valuation methodology for loans held-for-sale varies based upon the circumstances. Held-for-sale values may be based upon accepted offer amounts, appraised value of underlying mortgaged premises, prior loan loss experience of Carver in connection with recent loan sales for the loan type in question, and/or other acceptable valuation methods.
Loans Receivable | Loans Receivable Loans receivable are carried at unpaid principal balances plus unamortized premiums, certain deferred direct loan origination costs and deferred loan origination fees and discounts, less the allowance for loan losses and charge-offs. The Bank defers loan origination fees and certain direct loan origination costs and amortizes or accretes such amounts as an adjustment of yield over the contractual lives of the related loans using methodologies which approximate the interest method. Premiums and discounts on loans purchased are amortized or accreted as an adjustment of yield over the contractual lives of the related loans, adjusted for prepayments when applicable, using methodologies which approximate the interest method. Loans are placed on nonaccrual status when they are past due 90 days or more as to contractual obligations or when other circumstances indicate that collection is not probable. When a loan is placed on nonaccrual status, any interest accrued but not received is reversed against interest income. Payments received on a nonaccrual loan are either applied to protective advances, the outstanding principal balance or recorded as interest income, depending on an assessment of the ability to collect the loan. A nonaccrual loan may be restored to accrual status when principal and interest payments have been brought current and the loan has performed in accordance with its contractual terms for a reasonable period (generally six months). If the Bank determines, after considering factors such as payment status and collateral value, that a loan is impaired, the Bank next determines the amount of the impairment. The amount of impairment on collateral dependent loans is charged off within the given fiscal quarter. Generally the amount of the loan and negative escrow in excess of the appraised value less estimated selling costs, for the fair value of collateral valuation method, is charged off. For all other loans, impairment is measured as described below in Allowance for Loan and Lease Losses.
Allowance for Loan and Lease Losses (ALLL) | Allowance for Loan and Lease Losses ("ALLL") The adequacy of the Bank's ALLL is determined in accordance with ASC Subtopics 450-20 "Loss Contingencies" and 310-10 "Accounting by Creditors for Impairment of a Loan." Management reviews the Bank's loan portfolio to identify and review individual problem situations that may affect a borrower's ability to repay. In addition, management reviews the overall portfolio quality through an analysis of delinquency and non-performing loan data, estimates of the value of underlying collateral, current charge-offs and other factors that may affect the portfolio, including an assessment of current and expected economic conditions and changes in the size and composition of the loan portfolio. The ALLL reflects management's evaluation of the loans presenting identified loss potential, as well as the risk inherent in various components of the portfolio. There is significant judgment applied in estimating the ALLL. These assumptions and estimates are susceptible to significant changes based on the current environment. Further, any change in the size of the loan portfolio or any of its components could necessitate an increase in the ALLL even though there may not be a decline in credit quality or an increase in potential problem loans. The Bank utilizes an internal loan classification system as a means of reporting problem loans within its loan categories. Loans may be classified as "Pass," “Special Mention,” “Substandard,” “Doubtful,” and “Loss.” Loans rated Pass have demonstrated satisfactory asset quality, earning history, liquidity, and other adequate margins of creditor protection. They represent a moderate credit risk and some degree of financial stability. Loans are considered collectible in full, but perhaps require greater than average amount of loan officer attention. Borrowers are capable of absorbing normal setbacks without failure. Loans rated Special Mention have potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Bank's credit position at some future date. Loans rated Substandard are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified must have a well-defined weakness, or weaknesses, that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. Loans rated Doubtful have all the weaknesses inherent in those classified Substandard with the added characteristic that the weaknesses present make collection or liquidation in full, based on currently existing facts, conditions and values, highly questionable and improbable. Loans classified as Loss are those considered uncollectible with insignificant value and are charged off immediately to the allowance for loan losses. One-to-four family residential loans and consumer and other loans are rated non-performing if they are delinquent in payments ninety or more days, a troubled debt restructuring with less than six months contractual performance or past maturity. All other one-to-four family residential loans and consumer and other loans are performing loans. General Reserve Allowance Carver's maintenance of a general reserve allowance includes the Bank's evaluation of the risk to potential loss on homogeneous pools of loans based upon historical loss factors and a review of nine different environmental factors that are then applied to each pool. The pools of loans (“Loan Type”) are: •One-to-four family •Multifamily •Commercial Real Estate •Business Loans •Consumer (including Overdraft Accounts) The Bank next applies to each pool a risk factor that determines the level of general reserves for that specific pool. The Bank estimates its historical charge-offs via a lookback analysis. The actual historical loss experience by major loan category is expressed as a percentage of the outstanding balance of all loans within the category. As the loss experience for a particular loan category increases or decreases, the level of reserves required for that particular loan category also increases or decreases. The Bank’s historical charge-off rate reflects the period over which the charge-offs were confirmed and recognized, not the period over which the earlier losses occurred. That is, the charge-off rate measures the confirmation of losses over a period that occurs after the earlier actual losses. During the period between the loss-causing events and the eventual confirmations of losses, conditions may have changed. There is always a time lag between the period over which average charge-off rates are calculated and the date of the financial statements. During that period, conditions may have changed. Another factor influencing the General Reserve is the Bank’s loss emergence period ("LEP") assumptions which represent the Bank’s estimate of the average amount of time from the point at which a loss is incurred to the point at which the loss is confirmed, either through the identification of the loss or a charge-off. Based upon adequate management information systems and effective methodologies for estimating losses, management has established a LEP floor of one year on all pools. In some pools, such as Commercial Real Estate, Multifamily and Business pools, the Bank demonstrates a LEP in excess of 12 months. Because actual loss experience may not adequately predict the level of losses inherent in a portfolio, the Bank reviews nine qualitative factors to determine if reserves should be adjusted based upon any of those factors. As the risk ratings worsen, some of the qualitative factors tend to increase. The nine qualitative factors the Bank considers and may utilize are: 1.Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses (Policy & Procedures). 2.Changes in relevant economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments (Economy). 3.Changes in the nature or volume of the loan portfolio and in the terms of loans (Nature & Volume). 4.Changes in the experience, ability, and depth of lending management and other relevant staff (Management). 5.Changes in the volume and severity of past due loans, the volume of nonaccrual loans, and the volume and severity of adversely classified loans (Problem Assets). 6.Changes in the quality of the loan review system (Loan Review). 7.Changes in the value of underlying collateral for collateral dependent loans (Collateral Values). 8.The existence and effect of any concentrations of credit and changes in the level of such concentrations (Concentrations). 9.The effect of other external forces such as competition and legal and regulatory requirements on the level of estimated credit losses in the existing portfolio (External Forces). The following discussion describes the general risks associated with the Bank’s lending activities: •One-to-four family - Carver Federal purchases first mortgage loans secured by one-to-four family properties that serve as the primary residence of the owner. The loans are underwritten in accordance with applicable secondary market underwriting guidelines and requirements for sale. These loans present a moderate level of risk due primarily to general economic conditions. During fiscal year 2021, the Bank also started purchasing non-qualified mortgages for one-to-four family residential loans. The Bank has approved guidelines for these loans. •Multifamily - Carver Federal originates and purchases recourse and non-recourse multifamily loans. These loans can be affected by economic conditions and the value of the underlying properties. The Bank primarily considers the property's ability to generate net operating income sufficient to support the debt service, the financial resources, income level and managerial expertise of the borrower, the marketability of the property and the Bank's lending experience with the owner/guarantor. •Commercial - Commercial real estate ("CRE") lending consists predominantly of originating loans for the purpose of purchasing or refinancing office, mixed-use properties, retail and church buildings in the Bank's market area. Mixed-use loans are secured by properties that are intended for both commercial and residential use, but predominantly commercial, and are classified as CRE. In originating CRE loans, the Bank primarily considers the ability of the net operating income generated by the real estate to support the debt service, the financial resources, income level and managerial expertise of the borrower, the marketability of the property and the Bank's lending experience with the owner/guarantor. The Bank also requires the assignment of rents of all tenants' leases in the mortgaged property and personal guarantees may be obtained for additional security from these borrowers. CRE loans generally present a higher level of risk than other types of loans due primarily to the effect of general economic conditions and the complexities involved in valuing the underlying collateral. •Business - The Bank originates and purchases business and SBA loans primarily to businesses located in its primary market area and surrounding areas. Business loans are typically personally guaranteed by the owners and may also be secured by additional collateral, including real estate, equipment and inventory. Business loans are also subject to increased risk from the effect of general economic conditions. SBA loans are guaranteed by the U.S. government based on the percentage of each individual program. •Consumer - The Consumer portfolio includes student loans to medical students enrolled in several Caribbean schools, as well as unsecured consumer loans purchased from or originated through strategic partnerships with Bankers Healthcare Group, LLC and Upstart Holdings, Inc.. Specific Reserve Allowance Carver also maintains a specific reserve allowance for criticized and classified loans individually reviewed for impairment. The amount assigned to the specific reserve allowance is individually determined based upon the loan. Carver uses one of three methods to estimate the amount to be reserved and/or charged off for such credits. The three methods are as follows: 1.The present value of expected future cash flows discounted at the loan's effective interest rate; 2.The loan's observable market price; or 3.The fair value of the collateral if the loan is collateral dependent. The Bank may choose the appropriate method on a loan-by-loan basis for an individually impaired loan, except for an impaired collateral dependent loan. Impairment of a collateral dependent loan is measured using the fair value of collateral method. A loan is considered "collateral dependent" when the repayment of the debt will be provided solely by the underlying collateral, and there are no other available and reliable sources of repayment. All substandard and doubtful loans and any other loans that the Chief Credit Officer deems appropriate for review, are identified and reviewed for individual evaluation for impairment. Carver also performs impairment analysis for all troubled debt restructurings (“TDRs”). All TDRs are classified as impaired. For non-TDRs, if it is determined that it is probable the Bank will be unable to collect all amounts due according with the contractual terms of the loan agreement, the loan is categorized as impaired. Loans determined to be impaired are evaluated to determine the amount of impairment based on one of the three measurement methods noted above. In accordance with guidance, if there is no impairment amount, no reserve is established for the loan. An unallocated loan loss allowance is appropriate when it reflects an estimate of probable loss, determined in accordance with GAAP, and is properly supported.
Troubled Debt Restructured Loans | Troubled Debt Restructured Loans TDRs are those loans where the borrower is experiencing financial difficulty and a concession is made. A concession could include extension of the terms of the loan, reduced interest rates, capitalization of interest, a significant delay in payment terms and forgiveness of accrued interest and/or principal. Once an obligation has been restructured because of such credit problems, it continues to be considered a TDR until paid in full. For a collateral dependent loan, the Bank records an impairment charge when the current estimated fair value (less estimated costs of disposal) of the property that collateralizes the impaired loan, if any, is less than the recorded investment in the loan. For all other TDRs, the Bank records a specific valuation allowance reserve equal to the difference between the present value of estimated future cash flows under the restructured terms discounted at the loan's original effective interest rate, and the loan's recorded investment. TDR loans remain on nonaccrual status until they have performed in accordance with the restructured terms for a period of at least six months.
Representation and Warranty Reserve | Representation and Warranty Reserve During the period 2004 through 2009, the Bank originated 1-4 family residential mortgage loans and sold the loans to the Federal National Mortgage Association (“FNMA”). The loans were sold to FNMA with the standard representations and warranties for loans sold to the Government Sponsored Entities (GSEs). The Bank may be required to repurchase these loans in the event of breaches of these representations and warranties. In the event of a repurchase, the Bank is typically required to pay the unpaid principal balance as well as outstanding interest and fees. The Bank then recovers the loan or, if the loan has been foreclosed, the underlying collateral. The Bank is exposed to any losses on repurchased loans after giving effect to any recoveries on the collateral. Management has established a representation and warranty reserve for losses associated with the repurchase of mortgage loans sold by the Bank to FNMA that we consider to be both probable and reasonably estimable. These reserves are reported in the consolidated statement of financial condition as a component of other liabilities. The calculation of the reserve is based on estimates, which are uncertain, and require the application of judgment. In establishing the reserves, we consider a variety of factors, including those loans that are under review by FNMA that have not yet received a repurchase request. The Bank tracks the FNMA claims monthly and evaluates the reserve on a quarterly basis.
Segment Reporting | Segment Reporting The Company has determined that all of its activities constitute one reportable operating segment.
Concentration Risk | Concentration of Risk The Bank's principal lending activities are concentrated in loans secured by real estate, a substantial portion of which are located in New York City. Accordingly, the ultimate collectability of a substantial portion of the Company's loan portfolio is susceptible to changes in New York's real estate market conditions. Qualitative factors in the ALLL calculation considers the Bank's concentration risk.
Premises and Equipment | Premises and Equipment Premises and equipment are comprised of land, at cost, and buildings, building improvements, furnishings and equipment and leasehold improvements, at cost less accumulated depreciation and amortization. Depreciation and amortization charges are included in Non-Interest Expense in the consolidated statements of operations and are computed using the straight-line method over the following estimated useful lives:
Buildings and improvements | 10 to 25 years
Furnishings and equipment | 3 to 5 years
Leasehold improvements | Lesser of useful life or remaining term of lease
Maintenance, repairs and minor improvements are charged to non-interest expense in the period incurred.
Leases | LeasesLeases are classified as operating or finance leases at the lease commencement date. The Company includes lease renewal options in the lease term if it is reasonably certain the option will be exercised. Right-of-use assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of the lease payments over the lease term. The Company uses its incremental borrowing rate, which is the rate for a fully collateralized and fully amortizing loan with a maturity date that is similar to the lease term, at lease commencement to calculate the present value of lease payments when the implicit rate in a lease is not readily determinable.
Federal Home Loan Bank Stock | Federal Home Loan Bank Stock The FHLB-NY has assigned to the Bank a mandated membership stock purchase, based on the Bank's asset size. In addition, for all borrowing activity, the Bank is required to purchase shares of FHLB-NY non-marketable capital stock at par. Such shares are redeemed by FHLB-NY at par with reductions in the Bank's borrowing levels. FHLB stock does not have a readily determinable fair value and we do not consider these shares to be other-than-temporarily impaired at March 31, 2023. The Bank carries this investment at historical cost.
Mortgage Servicing Rights | Mortgage Servicing RightsAll separately recognized servicing assets totaled $152 thousand and $162 thousand, respectively, at March 31, 2023 and 2022, and are included in Other Assets in the consolidated statements of financial condition and measured at fair value. Changes in fair value is included in Non-Interest Income in the consolidated statements of operations. Servicing fee income of $44 thousand and $41 thousand, respectively, was recognized during the years ended March 31, 2023 and 2022, and is included in Non-Interest Income in the consolidated statements of operations.
Other Real Estate Owned | Other Real Estate OwnedReal estate acquired by foreclosure or deed-in-lieu of foreclosure is recorded at fair value at the date of acquisition less estimated selling costs. Any subsequent adjustments will be to the lower of cost or fair value and included in Non-Interest Expense in the consolidated statements of operations. The fair value of such assets is determined based primarily upon independent appraisals and other relevant factors. The amounts ultimately recoverable from real estate owned could differ from the net carrying value of these properties because of economic conditions. Costs incurred to improve properties or prepare them for sale are capitalized. Revenues and expenses related to the holding and operating of properties are recognized in operations as earned or incurred. Gains or losses on sale of properties are recognized as incurred and are included in Non-Interest Expense in the consolidated statements of operations. As of March 31, 2023, the Bank held $60 thousand in a foreclosed residential real estate property as a result of obtaining physical possession. In addition, as of March 31, 2023 and 2022, we had residential loans with a carrying value of $3.2 million and $3.1 million, respectively, collateralized by residential real estate property for which formal foreclosure proceedings were in process.
Income Taxes | Income Taxes The Company records income taxes using the asset and liability method. Income tax expense (benefit) consists of income taxes currently payable (receivable) and deferred income taxes. Temporary differences between the basis of assets and liabilities for financial reporting and tax purposes are measured as of the balance sheet date. Deferred tax liabilities or recognizable deferred tax assets are calculated on such differences, using current statutory rates, which result in future taxable or deductible amounts. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. Where applicable, deferred tax assets are reduced by a valuation allowance for any portion determined more likely than not to be realized. This valuation allowance would subsequently be adjusted by a charge or credit to income tax expense as changes in facts and circumstances warrant. A tax position is recognized as a benefit only if it is "more likely than not" that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. Any interest expense or penalties would be recorded as interest expense.
Earnings (Loss) per Common Share | Earnings (Loss) per Common Share The Company has preferred stock which are entitled to receive dividends if declared on the Company's common stock and are therefore considered to be participating securities. Basic earnings (loss) per share (“EPS”) is computed using the two class method. This calculation divides net income (loss) available to common stockholders after the allocation of undistributed earnings to the participating securities by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share takes into account the potential dilution that could occur if securities or other contracts to issue common stock were exercised and converted into common stock. These potentially dilutive shares are then included in the weighted average number of shares outstanding for the period. Dilution calculations are not applicable to net loss periods.
Preferred and Common Dividends | Preferred and Common Dividends The Company is prohibited from paying any dividends without prior regulatory approval pursuant to the terms of the Formal Agreement and Resolution to which it is subject, and is generally subject to regulations governing the payment of dividends. There are no assurances that the payments of common stock dividends will resume.
Treasury Stock | Treasury Stock Treasury stock is recorded at cost and is presented as a reduction of stockholders' equity.
Stock Compensation Plans | Stock Compensation Plans The Company currently has multiple stock plans in place for employees and directors of the Company. The compensation cost related to share-based payment transactions is included in Employee Compensation and Benefits in the consolidated statements of operations. Compensation cost for all stock awards is calculated and recognized over a defined vesting period. Forfeitures are accounted for as they occur. For awards with graded-vesting, compensation cost is recognized on a straight-line basis over the requisite vesting period for the entire award. The Black-Scholes model is used to estimate the fair value of stock options, while the market price of the Company's common stock at the date of grant is used for restricted stock awards.
Off-Balance-Sheet Financial Instruments | Off-Balance Sheet Financial Instruments In the ordinary course of business, the Bank has entered into off-balance sheet financial instruments consisting of commitments to extend credit and letters of credit. Such financial instruments are recorded in the consolidated statements of condition when they are funded. Reserves for unfunded lending commitments are included in Other Liabilities in the consolidated statements of financial condition.
Grant Income | Grant IncomeDesignated as a Community Development Financial Institution ("CDFI") by the U.S. Department of the Treasury, the Bank is eligible for, and on occasion receives, assistance from the government and other financial institutions in the form of grants. The Company earns these grants through compliance with their conditions and by meeting the stated obligations. The Company therefore recognizes the grant income over the periods that bear the cost of meeting the obligations.
Advertising Costs | Advertising Costs The Company follows the policy of charging the costs of advertising to expense as incurred.
Transfers of Financial Assets | Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Recent Accounting Standards | Recent Accounting Standards Accounting Standards Recently Adopted On April 1, 2021, the Company adopted ASU No. 2019-12 "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes," which was part of the FASB's simplification initiative to reduce complexity, while maintaining or improving the usefulness of information provided to users of financial statements. The amendments in this update simplified the accounting for income taxes and improved consistent application of GAAP by removing certain exceptions and clarifying and amending existing guidance for areas of Topic 740. The adoption of the standard did not have a material impact on the Company's financial statements. In November 2021, the FASB issued ASU No. 2021-10 "Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance," to improve the financial reporting of government assistance received by business entities by requiring the disclosure of (1) the types of assistance received, (2) an entity’s accounting for the assistance, and (3) the effect of the assistance on an entity’s financial statements. ASU 2021-10 is effective for all entities for financial statements issued for annual periods beginning after December 15, 2021 (for the Company, the fiscal year ending March 31, 2023). Early application of the guidance is permitted. The adoption of the standard did not have a material impact on the Company's financial statements. Accounting Standards Not Yet Adopted In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Loss," which replaces the guidance on recognition and measurement of credit losses for financial assets. The new requirements, known as the current expected credit loss model ("CECL") will require entities to adopt an impairment model based on expected losses rather than incurred losses. ASU No. 2016-13 is effective for fiscal years beginning after December 15, 2019 (for the Company, the fiscal year ending March 31, 2021), including interim periods within those fiscal years. In May 2019, the FASB issued ASU No. 2019-05, "Financial Instruments - Credit Losses (Topic 326): Target Transition Relief," to provide transition relief by giving entities an option to irrevocably elect the fair value option for certain financial assets measured at amortized cost upon adoption of ASU 2016-13. In November 2019, the FASB issued ASU No. 2019-10, which extended the CECL implementation date for smaller reporting companies, as defined by the SEC. The new effective date is for fiscal years beginning after December 15, 2022 (for the Company, the fiscal year ending March 31, 2024), including interim periods within those fiscal years. In November 2019, the FASB issued ASU No. 2019-11, "Codification Improvements to Topic 326, Financial Instruments - Credit Losses," to amend or clarify guidance regarding expected recoveries for purchased financial assets with credit deterioration, transition relief for troubled debt restructurings, disclosures related to accrued interest receivables, and financial assets secured by collateral maintenance provisions. The Company has conducted testing of the ASU 2016-13 method utilizing historical financial analysis and has engaged a vendor as an additional resource to examine and reaffirm the models as it relates to the implementation of the new methodology utilizing the current expected credit loss model, which will replace our current incurred loss approach. Based on the Company's current CECL model results that it has performed alongside the current process, the adoption of the new guidance will result in an increase of approximately $0.7 million to the allowance for credit loss, including the reserve for off-balance sheet credit exposure recorded in other liabilities. There is no material impact for other assets within the scope of the new CECL guidance, such as held-to-maturity debt securities and other receivables. The Company will adopt ASU 2016-13 effective April 1, 2023. As the Company finalizes the CECL implementation, final decisions made by management may result in a different impact than that stated above for financial statement disclosure purposes. In March 2022, the FASB issued ASU No. 2022-02, "Financial Instruments - Credit Losses (ASC 326): Troubled Debt Restructurings (TDRs) and Vintage Disclosures," which eliminates the accounting guidance for TDRs by creditors, while enhancing disclosure requirements for certain loan refinancing and restructuring activities by creditors when a borrower is experiencing financial difficulty. The amendments also require disclosure of current period gross writeoffs by year of origination. The effective dates for the amendments in ASU 2022-02 are the same as the effective dates in ASU 2016-13. The Company does not expect the adoption of this ASU to have a material impact on the consolidated financial statements. In March 2020, the FASB issued ASU No. 2020-04 "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting," which provides optional expedients and exceptions for applying GAAP to loan and lease agreements, derivative contracts, and other transactions affected by the anticipated transition away from LIBOR toward new interest rate benchmarks. For transactions that are modified because of reference rate reform and that meet certain scope guidance (i) modifications of loan agreements should be accounted for by prospectively adjusting the effective interest rate and the modification will be considered "minor" so that any existing unamortized origination fees/costs would carry forward and continue to be amortized and (ii) modifications of lease agreements should be accounted for as a continuation of the existing agreement with no reassessments of the lease classification and the discount rate or remeasurements of lease payments that otherwise would be required for modifications not accounted for as separate contracts. ASU 2020-04 is effective March 12, 2020 through December 31, 2022. An entity may elect to apply ASU 2020-04 for contract modifications as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. Once elected for a Topic or an Industry Subtopic, the amendments in this ASU must be applied prospectively for all eligible contract modifications for that Topic or Industry Subtopic. In December 2022, the FASB issued ASU No. 2022-06 "Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848," which defers the sunset date of Topic 848 from December 31, 2022 to December 31, 2024, after which entities will no longer be permitted to apply for relief in Topic 848. We anticipate this ASU will simplify any modifications we execute between the selected start date (yet to be determined) and December 31, 2024 that are directly related to LIBOR transition by allowing prospective recognition of the continuation of the contract, rather than extinguishment of the old contract resulting in writing off unamortized fees/costs. The Company is evaluating the impacts of this ASU and has not yet determined whether LIBOR transition and this ASU will have a material impact on the Company's consolidated statements of financial condition and results of operations.
