Accounting Policies [Abstract] |
Basis of Accounting, Policy [Policy Text Block] | Basis of Presentation: BankFinancial Corporation, a Maryland corporation headquartered in Burr Ridge, Illinois, is the owner of all of the issued and outstanding capital stock of BankFinancial, National Association (the “Bank”). BankFinancial Corporation is a registered Bank Holding Company and its wholly-owned bank subsidiary is operating as BankFinancial, National Association.
Consolidation, Policy [Policy Text Block] | Principles of Consolidation: The consolidated financial statements include the accounts of and transactions of BankFinancial Corporation, the Bank, and the Bank’s wholly-owned subsidiaries, Financial Assurance Services, Inc. and BFIN Asset Recovery Company, LLC (formerly BF Asset Recovery Corporation) (collectively, “the Company”) and have been prepared in conformity with accounting principles generally accepted in the United States of America (“US GAAP”). All significant intercompany accounts and transactions have been eliminated. The Company’s revenues, operating income, and assets are primarily from the banking industry. To supplement loan originations, the Company purchases loans. The loan portfolio is concentrated in loans that are primarily secured by real estate.
Use of Estimates, Policy [Policy Text Block] | Use of Estimates: The preparation of the consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Although these estimates and assumptions are based on the best available information, actual information, and actual results could differ from those estimates.
Subsequent Events, Policy [Policy Text Block] | Subsequent events: The Company has evaluated subsequent events for potential recognition and/or disclosures through the date the consolidated financial statements included in this Annual Report on Form 10-K were issued.
Interest-bearing Deposits in Other Financial Institutions [Policy Text Block] | Interest-bearing Deposits in Other Financial Institutions: Interest-bearing deposits in other financial institutions maturing in less than 90 days are carried at cost.
Cash and Cash Equivalents, Policy [Policy Text Block] | Cash Flows: Cash and cash equivalents include cash, deposits with other financial institutions maturing in less than 90 days, and daily federal funds sold. Net cash flows are reported for customer loan and deposit transactions, interest bearing deposits in other financial institutions, borrowings, and advance payments by borrowers for taxes and insurance.
Marketable Securities, Policy [Policy Text Block] | Securities: Debt securities are classified as available-for-sale when they might be sold before maturity. Securities available-for-sale are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income (loss), net of tax. Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are amortized on the level-yield method without anticipating prepayments, except for mortgage-backed securities where prepayments are anticipated. Gains and losses on sales are based on the amortized cost of the security sold. Realized gains and losses from sales are included in other non-interest income. Securities available-for-sale in an unrealized loss position, are evaluated to determine whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and any adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Adjustments to the allowance are reported in our income statement as a component of provision for credit losses. Securities also include investments in certificates of deposit with maturities of greater than 90 days. These certificates of deposit are placed with insured institutions for varying maturities and amounts that are fully insured by the Federal Deposit Insurance Corporation (“FDIC”).
Federal Home Loan Bank Stock, Policy [Policy Text Block] | Federal Home Loan Bank (“FHLB”) Stock: The Bank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income.
Federal Reserve Bank Stock, Policy [Policy Text Block] | Federal Reserve Bank (“FRB”) Stock: The Bank is a member of its regional Federal Reserve Bank. FRB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income.
Financing Receivable, Fee and Interest Income [Policy Text Block] | Loans and Loan Income: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding, net of the allowance for credit losses, premiums and discounts on loans purchased, and net deferred fees and loan costs. Interest income on loans is recognized in income over the term of the loan based on the amount of principal outstanding. Premiums and discounts associated with loans purchased are amortized over the contractual term of the loan using the level–yield method. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income using the level-yield method without anticipating prepayments. Interest income is reported on the interest method. Interest income is generally discontinued at the earlier of when a loan is 90 days past due or when we do not expect to receive full payment of interest or principal. Past due status is based on the contractual terms of the loan. All interest accrued but not received for loans that have been placed on nonaccrual status is reversed against interest income. Interest received on such loans is accounted for on the cash–basis or cost–recovery method until qualifying for return to accrual status. Once a loan is placed on nonaccrual status, the borrower must generally demonstrate at least six months of payment performance before the loan is eligible to return to accrual status. Generally, the Company utilizes the “90 days delinquent, still accruing” category of loan classification when: (1) the loan is repaid in full shortly after the period end date; (2) the loan is well secured and there are no asserted or pending legal barriers to its collection; or (3) the borrower has remitted all scheduled payments and is otherwise in substantial compliance with the terms of the loan, but the processing of payments actually received or the renewal of a loan has not occurred for administrative reasons. Factored Receivables: The Company purchases invoices from its factoring customers in schedules or batches. The face value of the invoices purchased or amount advanced is recorded by the Company as factored receivables, and the unadvanced portions of the invoices purchased, less fees, are considered customer reserves. The customer reserves are held to settle any payment disputes or collection shortfalls, may be used to pay customers’ obligations to various third parties as directed by the customer, are periodically released to or withdrawn by customers, and are reported as noninterest-bearing deposits in the Consolidated Statements of Financial Condition. The unpaid principal balances of these receivables were $5.9 million and $7.0 million at December 31, 2023 and December 31, 2022, respectively and are included in commercial loans and leases. The customer reserves associated with the factored receivables were $2.1 million and $1.4 million at December 31, 2023 and December 31, 2022, respectively. Factoring fees are recognized in interest income as incurred by the customer and deducted from the customer's reserve balances. Other factoring-related fees, which include wire transfer fees, broker fees, and other similar fees, are reported by the Company as loan servicing fees in noninterest income.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block] | Allowance for Credit Losses: On January 1, 2023, the Company adopted Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments (“ASC 326”). ASC 326 amends guidance on reporting credit losses for financial assets held at amortized cost basis and available-for-sale debt securities. ASC 326 eliminates the probable initial recognition threshold in current US GAAP and instead, requires an entity to reflect its current estimate of all expected credit losses based on historical experience, current conditions and reasonable and supportable forecasts. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial assets to present the net amount expected to be collected. ASC 326 also expands the disclosure requirements regarding an entity’s assumptions, models, and methods for estimating the reserve for credit losses. In addition, entities need to disclose the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination. The Company adopted ASC 326 using the modified retrospective approach. Results for the periods beginning after January 1, 2023 are presented under Accounting Standards Codification 326 while prior period amounts continue to be reported in accordance with previously applicable US GAAP. The Company recorded a net reduction of retained earnings of $1.7 million upon adoption. The transition adjustment includes an increase in credit related reserves of $1.9 million and the recording of an unfunded commitment reserve of $417,000, respectively, net of the corresponding increase in deferred tax assets of $604,000.

The allowance for credit losses (“ACL”) is evaluated on a regular basis and established through charges to earnings in the form of a provision for credit losses. When a loan or portion of a loan is determined to be uncollectible, the portion deemed uncollectible is charged against the allowance and subsequent recoveries, if any, are credited to the allowance. This valuation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. a. Portfolio Segmentation (“Pooled Loans”) Portfolio segmentation is defined as the pooling of loans based upon similar risk characteristics such that quantitative methodologies and qualitative adjustment factors for estimating the allowance for credit losses is constructed for each segment. The allowance for credit losses for Pooled Loans estimate is based upon periodic review of the collectability of the loans quantitatively correlating historical loan experience with reasonable and supportable forecasts using forward looking information. Adjustments to the quantitative evaluation may be made for differences in current or expected qualitative risk characteristics such as changes in: underwriting standards, delinquency level, regulatory environment, economic condition, Company management and the status of portfolio administration including the Company’s Loan Review function. b. Individually Evaluated Loans The Company establishes a specific loss reserve for individually evaluated loans which do not share similar risk characteristics with the loans included in the forecasted allowance for credit losses. These individually evaluated loans are removed from the pooling approach discussed above for the forecasted allowance for credit losses, and include nonaccrual loans and other loans deemed appropriate by management. Nonaccrual and classified loans are reviewed on a monthly basis to determine if (a) an amount is deemed uncollectible (a charge-off) or (b) it is probable that the Company will be unable to collect amounts due in accordance with the original contractual terms of the loan. In cases in which collectability is not probable, the loan is considered to no longer exhibit shared risk characteristics of a pool and as a result, is individually evaluated for allowance for credit losses measurement purposes. If a loan is individually evaluated, the carrying amount of the loan is compared to the expected payments to be received, discounted at the loan’s original rate, or for foreclosure-probable and collateral dependent loans, to the fair value of the collateral less the estimated costs to sell, when appropriate under accounting rules. Any shortfall is recorded as a specific reserve within the allowance for credit losses or a charge-off. c. Accrued Interest Receivable Upon adoption of ASC 326 and its related amendments on January 1, 2023, the Company made the following elections regarding accrued interest receivable:
● | Presenting accrued interest receivable balances separately within another line item on the Consolidated Statements of Financial Condition.
● | Continuing our policy to fully reserve accrued interest receivable by reversing interest income. For commercial loans, the reserve is established upon becoming 90 days past due. For consumer loans, the charge-off typically occurs upon becoming 120 days past due. Historically, the Company has not experienced uncollectible accrued interest receivable on its investment securities.
● | Not measuring an allowance for credit losses for accrued interest receivable due to the Company’s policy of fully reserving uncollectible accrued interest receivable balances in a timely manner, as described above.
d. Reserve for Unfunded Commitments The reserve for unfunded commitments (the “Unfunded Commitment Reserve”) represents the expected credit losses on off-balance sheet commitments such as unfunded commitments to extend credit and standby letters of credit. However, a liability is not recognized for commitments that are unconditionally cancellable by the Company. The Unfunded Commitment Reserve is recognized as a liability (other liabilities on the Consolidated Statements of Financial Condition), with adjustments to the unfunded commitment reserve recognized as a provision for credit loss expense in the Consolidated Statements of Income. The Unfunded Commitment Reserve is determined by estimating expected future fundings, under each segment, and applying the expected loss rates. Expected future fundings are based on historical averages of funding rates (i.e., the likelihood of draws taken). To estimate future fundings on unfunded balances, current funding rates are compared to historical funding rates. Determining the Allowance for Credit Losses The allowance for credit losses on financial assets held at amortized cost is measured on a collective or pooled basis when similar risk characteristics exist, based upon management's loan portfolio segmentation. The Company utilizes modeling methodologies that estimate lifetime credit loss rates on each pool, including methodologies estimating the probability of default and loss given default on specific segments. Expected credit losses are measured over the contractual term of the financial asset with consideration of expected prepayments. A “life of loan” credit loss shall estimate expected credit losses over the contractual term of the financial asset. This includes not extending the contractual term for expected extensions, renewals, and modifications. Discounted Cash Flow methodologies work properly with an amortizing approach. Loans without maturity dates may not have a true exit or end of life. For consistency in its methodology, management elected to use maturity date assumptions for loans without maturity dates; pool-level assumptions have been assigned by management. Credit quality indicators, specifically the Company's internal risk rating systems, reflect how the Company monitors credit losses and represent factors used by the Company when measuring the allowance for credit losses. Historical credit loss history is adjusted for reasonable and supportable forecasts that incorporates peer institution data and third party economic forecasts on a quantitative or qualitative basis. Reasonable and supportable forecasts consider the macroeconomic factors that are most relevant to evaluating and predicting expected credit losses in the Company's financial assets. Qualitative factors assessed by management include the following:
• | Changes in lending policies and procedures, including changes in underwriting standards and collections, charge-offs, and recovery practices; |
• | Changes in national, regional, and local conditions; |
• | Changes in the nature and volume of the portfolio and terms of loans (inherent risk); |
• | Changes in the experience, depth, and ability of lending management; |
• | Changes in the volume and severity of past due loans and other similar conditions; |
• | Changes in the quality of the organization's loan review system; |
• | Changes in the value of underlying collateral for collateral dependent loans; |
• | The existence and effect of any concentrations of credit and changes in the levels of such concentrations; and |
• | The effect of other external factors (i.e. competition, legal and regulatory requirements) on the level of estimated credit losses. |
Financial assets that do not share similar risk characteristics with any pool are assessed for the allowance for credit losses on an individual basis. These typically include assets experiencing financial difficulties, including substandard nonaccrual assets and assets currently classified. Classified loans are reviewed on a quarterly basis to determine if (a) an amount is deemed uncollectible (a charge-off) or (b) it is probable that the Company will be unable to collect amounts due in accordance with the original contractual terms of the loan. In cases in which collectability is not probable, the loan is considered to no longer exhibit shared risk characteristics of a pool and as a result, is individually evaluated for allowance for credit losses measurement purposes. If a loan is individually evaluated, the carrying amount of the loan is compared to the expected payments to be received, discounted at the loan’s original rate, or for foreclosure-probable and collateral dependent loans, to the fair value of the collateral less the estimated cost to sell, when appropriate under accounting rules. Any shortfall is recorded as a specific reserve within the allowance for credit losses.
Financing Receivable, Troubled Debt Restructuring [Policy Text Block] | Troubled Debt Restructurings and Vintage Disclosures: ASU 2022-02 “Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures” eliminates the Troubled Debt Restructurings (“TDR”) accounting model for creditors that have already adopted ASC 326. In lieu of the TDR accounting model, loan refinancing and restructuring guidance in ASC Subtopic 310-20 “Investments—Debt Securities” will apply to all loan modifications, including those made for borrowers experiencing financial difficulty. This standard also enhances disclosure requirements related to certain loan modifications. Additionally, this standard introduces new requirements to disclose gross write-off information in the vintage disclosures of financing receivables by credit quality indicator and class of financing receivable by year of origination. The Company adopted the standard on January 1, 2023
Financing Receivable, Real Estate Acquired Through Foreclosure [Policy Text Block] | Foreclosed Assets: Foreclosed assets are initially recorded at fair value less cost to sell when acquired, establishing a new cost basis. Physical possession of residential real estate property collateralizing a consumer mortgage loan occurs when the legal title is obtained upon completion of foreclosure or when the borrower conveys all interest in the property to satisfy the loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. These assets are subsequently accounted for at a lower of cost or fair value less estimated cost to sell. Assets are classified as foreclosed when physical possession of the collateral is taken regardless of whether foreclosure proceedings have taken place. Other foreclosed assets received in satisfaction of borrowers’ debt are initially recorded at fair value of the asset less estimated costs to sell. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Operating expenses, gains and losses on disposition, and changes in the valuation allowance are reported in noninterest expense as operations of foreclosed assets.
Property, Plant and Equipment, Policy [Policy Text Block] | Premises and Equipment: Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. Depreciation is included in noninterest expense and is computed on the straight-line method over the estimated useful lives of the assets. Useful lives are estimated to be 25 to 40 years for buildings and improvements that extend the life of the original building, ten to 20 years for routine building improvements, five to 15 years for furniture and equipment, two to five years for computer hardware and software and no greater than four years on automobiles. The cost of maintenance and repairs is charged to expense as incurred and significant repairs are capitalized.
Lessee, Leases [Policy Text Block] | Lease Accounting: The Company adopted FASB ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”), including the adoption of the practical expedients, effective January 1, 2019. Leases (Topic 842) establishes a right of use model that requires a lessee to record a right of use (“ROU”) asset and a lease liability for all leases with terms longer than 12 months. The Company enters into operating leases in the normal course of business primarily for several of its branch and corporate locations. Currently the Company is obligated under six non-cancellable operating lease agreements for branch properties, commercial credit origination and customer service offices and its corporate office. The leases have varying terms, the longest of which will end in 2032. The Company's lease agreements include options to renew at the Company's discretion. The extensions are not reasonably certain to be exercised; therefore, they were not considered in the calculation of the ROU asset and lease liability. The Company has also elected not to recognize leases with original lease terms of 12 months or less (short-term leases) in the Company's Consolidated Statement of Financial Condition. The ROU assets are included in other assets and the lease obligations are included in other liabilities in the accompanying Consolidated Statements of Financial Condition.
Life Insurance Corporate Or Bank Owned [Policy Text Block] | Bank-Owned Life Insurance: The Company has purchased life insurance policies on certain key executives. The Company owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Impairment or Disposal of Long-Lived Assets, Including Intangible Assets, Policy [Policy Text Block] | Long-Term Assets: Premises and equipment, right of use assets, and other long-term assets are reviewed for impairment when events indicate that their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value.
Loan Commitments, Policy [Policy Text Block] | Loan Commitments and Related Financial Instruments: Financial instruments include off-balance-sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.
Income Tax, Policy [Policy Text Block] | Income Taxes: Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Under US GAAP, a deferred tax asset valuation allowance is required to be recognized if it is “more likely than not” that the deferred tax asset will not be realized. The determination of the realizability of the deferred tax assets is highly subjective and dependent upon judgment concerning management’s evaluation of both positive and negative evidence, the forecasts of future taxable income, applicable tax planning strategies, and assessments of current and future economic and business conditions. The Company considers both positive and negative evidence regarding the ultimate realizability of our deferred tax assets. Examples of positive evidence may include the existence, if any, of taxes paid in available carry-back years and the likelihood that taxable income will be generated in future periods. Examples of negative evidence may include a cumulative loss in the current year and prior two years and negative general business and economic trends. Deferred tax assets and liabilities 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 deferred tax assets and liabilities of a change in tax rates is recognized in income in the period of the enactment date. This analysis is updated quarterly and adjusted as necessary. At December 31, 2023 and 2022, the Company had a net deferred tax asset of $4.5 million and $5.5 million, respectively. 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, presuming that a tax examination will occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely to be realized on examination. For tax positions not meeting the "more likely than not" test, no tax benefit is recorded.
Pension and Other Postretirement Plans, Policy [Policy Text Block] | Retirement Plans: Employee 401(k) and profit sharing plan expense is the amount of matching contributions and any annual discretionary contribution made at the discretion of the Company’s Board of Directors.
Earnings Per Share, Policy [Policy Text Block] | Earnings per Common Share: Basic earnings per common share is net income divided by the weighted average number of common shares outstanding during the period. Diluted earnings per common share is net income divided by the weighted average number of common shares outstanding during the period plus the dilutive effect of potential common shares.
Commitments and Contingencies, Policy [Policy Text Block] | Loss Contingencies: Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe that there are such matters that will have a material effect on the financial statements as of December 31, 2023.
Fair Value of Financial Instruments, Policy [Policy Text Block] | Fair Values of Financial Instruments: Fair values of financial instruments are estimated using relevant market value information and other assumptions, as more fully disclosed in a separate note. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates.
Comprehensive Income, Policy [Policy Text Block] | Comprehensive Income: Comprehensive income consists of net income and other comprehensive income (loss). Other comprehensive income (loss) includes unrealized gains and losses on securities, net of tax, which is also recognized as separate components of stockholders’ equity.
Transfers and Servicing of Financial Assets, Policy [Policy Text Block] | Transfers of Financial Assets: Transfers of financial assets are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, 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 the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Segment Reporting, Policy [Policy Text Block] | Operating Segments: While management monitors the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Company-wide basis. Operating results are not reviewed by senior management to make resource allocation or performance decisions. Accordingly, all of the financial service operations are considered by management to be aggregated in one reportable operating segment.
Reclassification, Comparability Adjustment [Policy Text Block] | Reclassifications: Certain reclassifications have been made in the prior year’s financial statements to conform to the current year’s presentation. Reclassifications had no effect on prior year net income or stockholders’ equity.
New Accounting Pronouncements, Policy [Policy Text Block] | Recently Issued Accounting Standards Not Yet Adopted In December 2023, the FASB issued ASU 2023‑09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which requires more detailed disclosures of income taxes paid net of refunds received, income from continuing operations before income tax expense or benefit, and income tax expense from continuing operations. This standard is to be applied on a prospective basis, with retrospective application permitted, and will be effective for the Company for annual periods beginning on January 1, 2025. We do not expect adoption of this standard to have a material impact on the Company’s financial position or results of operations.
