Organization, Consolidation and Presentation of Financial Statements [Abstract]

Summary of Significant Accounting Policies

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.

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. Loan origination customers are mainly located in the greater Chicago metropolitan area. 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: The preparation of the consolidation 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, actual results could differ from those estimates.

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 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.

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. Declines in the fair value of securities below their cost that are other-than-temporary are reflected as realized losses. In determining if losses are other-than-temporary, management considers: (1) the length of time and extent that fair value has been less than cost or adjusted cost, as applicable, (2) the financial condition and near term prospects of the issuer, and (3) whether the Company has the intent to sell the debt security or it is more likely than not that the Company will be required to sell the debt security before the anticipated recovery.

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”).

Equity Securities: Equity securities are accounted for in accordance with ASC 321-10 Investments - Equity Securities. Our equity securities may be classified into two categories and accounted for as follows:


•	Equity securities with a readily determinable fair value are reported at fair value, with unrealized gains and losses included in earnings. Any dividends received are recorded in interest income.


•	Equity securities without a readily determinable fair value are reported at their cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer and their impact on fair value. Any dividends received are recorded in interest income.

The fair value of equity investments with readily determinable fair values is primarily obtained from third-party pricing services. For equity investments without readily determinable fair values, when an orderly transaction for the identical or similar investment of the same issuer is identified, we use the valuation techniques permitted under ASC 820 Fair Value to evaluate the observed transaction(s) and adjust the fair value of the equity investment.

ASC 321-10 also provides guidance related to accounting for impairment of equity securities without readily determinable fair values. The qualitative assessment to determine whether impairment exists requires the use of our judgment in certain circumstances. If, after completing the qualitative assessment we conclude an equity investment without a readily determinable fair value is impaired, a loss for the difference between the equity investment’s carrying value and its fair value may be recognized as a reduction to noninterest income in the Consolidated Statements of Operations.

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 (“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.

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 loan losses, premiums and discounts on loans purchased, and net deferred 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 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.

Impaired Loans: Impaired loans principally consist of nonaccrual loans and troubled debt restructurings (“TDRs”). A loan is considered impaired when, based on current information and events, management believes that it is probable that we will be unable to collect all amounts due (both principal and interest) according to the original contractual terms of the loan agreement. Once a loan is determined to be impaired, the amount of impairment is measured based on the loan's observable fair value, the fair value of the underlying collateral less selling costs if the loan is collateral-dependent, or the present value of expected future cash flows discounted at the loan's effective interest rate. If the measurement of the impaired loan is less than the recorded investment in the loan, the bank's allowance for the impaired collateral dependent loan under ASC 310-10-35 is based on fair value (less costs to sell), but the charge-off (the confirmed “loss”) is based on the appraised value. The remaining recorded investment in the loan after the charge-off will have a loan loss allowance for the amount by which the estimated fair value of the collateral (less costs to sell) is less than its appraised value.

Impaired loans with specific reserves are reviewed quarterly for any changes that would affect the specific reserve. Any impaired loan for which a determination has been made that the economic value is permanently reduced is charged-off against the allowance for loan losses to reflect its current economic value in the period in which the determination has been made.

At the time a collateral-dependent loan is initially determined to be impaired, we review the existing collateral appraisal. If the most recent appraisal is greater than a year old, a new appraisal is obtained on the underlying collateral. Appraisals are updated with a new independent appraisal at least annually and are formally reviewed by our internal appraisal department upon receipt of a new appraisal. All impaired loans and their related reserves are reviewed and updated each quarter.

Troubled Debt Restructurings: A loan is classified as a troubled debt restructuring when a borrower is experiencing financial difficulties that leads to a restructuring of the loan, and the Company grants concessions to the borrower in the restructuring that it would not otherwise consider. These concessions may include rate reductions, principal forgiveness, extension of maturity date and other actions intended to minimize potential losses.

In determining whether a debtor is experiencing financial difficulties, the Company considers if the debtor is in payment default or would be in payment default in the foreseeable future without the modification, the debtor declared or is in the process of declaring bankruptcy, there is substantial doubt that the debtor will continue as a going concern, the debtor has securities that have been or are in the process of being delisted, the debtor's entity-specific projected cash flows will not be sufficient to service any of its debt, or the debtor cannot obtain funds from sources other than the existing creditors at a market rate for debt with similar risk characteristics.

In determining whether the Company has granted a concession, the Company assesses, if it does not expect to collect all amounts due, whether the current value of the collateral will satisfy the amounts owed, whether additional collateral or guarantees from the debtor will serve as adequate compensation for other terms of the restructuring, and whether the debtor otherwise has access to funds at a market rate for debt with similar risk characteristics.

Periodically, the Company will restructure a note into two separate notes (A/B structure), charging off the entire B portion of the note. The A note is structured with appropriate loan-to-value and cash flow coverage ratios that provide for a high likelihood of repayment. The A note is classified as a nonperforming note until the borrower has displayed a historical payment performance for a reasonable time prior to and subsequent to the restructuring. A period of sustained repayment for at least six months generally is required to return the note to accrual status provided that management has determined that the performance is reasonably expected to continue. The A note will be classified as a restructured note (either performing or nonperforming) through the calendar year of the restructuring that the historical payment performance has been established.

Allowance for Loan Losses: The Company establishes provisions for loan losses, which are charged to the Company’s results of operations to maintain the allowance for loan losses to absorb probable incurred credit losses in the loan portfolio. In determining the level of the allowance for loan losses, the Company considers past and current loss experience, trends in classified loans, evaluations of real estate collateral, current economic conditions, volume and type of lending, adverse situations that may affect a borrower’s ability to repay a loan and the levels of nonperforming and other classified loans. The amount of the allowance is based on estimates and the ultimate losses may vary from the estimates as more information becomes available or events change.

The Company provides for loan losses based on the allowance method. Accordingly, all loan losses are charged to the related allowance and all recoveries are credited to it. Additions to the allowance for loan losses are provided by charges to income based on various factors that, in our judgment, deserve current recognition in estimating probable incurred credit losses. The Company reviews the loan portfolio on an ongoing basis and makes provisions for loan losses on a quarterly basis to maintain the allowance for loan losses in accordance with US GAAP. The allowance for loan losses consists of two components:


•	specific allowances established for any impaired residential non-owner occupied mortgage, multi-family mortgage, nonresidential real estate, construction and land, commercial, and commercial lease loans for which the recorded investment in the loan exceeds the measured value of the loan; and


•	general allowances for loan losses for each loan class based on historical loan loss experience; and adjustments to historical loss experience (general allowances), maintained to cover uncertainties that affect our estimate of probable incurred credit losses for each loan class.

The adjustments to historical loss experience are based on our evaluation of several factors, including levels of, and trends in, past due and classified loans; levels of, and trends in, charge–offs and recoveries; trends in volume and terms of loans, including any credit concentrations in the loan portfolio; experience and ability of lending management and other relevant staff; and national and local economic trends and conditions.

The Company evaluates the allowance for loan losses based upon the combined total of the specific and general components. Generally, when the loan portfolio increases, absent other factors, the allowance for loan loss methodology results in a higher dollar amount of estimated probable incurred credit losses than would be the case without the increase. Conversely, when the loan portfolio decreases, absent other factors, the allowance for loan loss methodology generally results in a lower dollar amount of estimated probable losses than would be the case without the decrease.

The loss ratio used in computing the required general loan loss reserve allowance for a given class of loan consists of (i) the actual loss ratio (measured on a weighted, rolling twelve-quarter basis), (ii) the change in credit quality within the specific loan class during the period, (iii) the actual inherent risk factor assigned to the specific loan class and (iv) the actual concentration of risk factor assigned to the specific loan class (collectively, the “Specific Loan Class Risk Factors”). The Specific Loan Class Risk Factors are weighted equally in the calculation. In addition, two additional quantitative factors, the National Economic risk factor and the Local Economic risk factor, are also components of the computation but are given different weightings in their computation due to their relative applicability to the specific loan class in the context of the effect of national and local economic conditions on their risk profile and performance.

Mortgage Servicing Rights: Mortgage servicing rights are recognized separately when they are acquired through sales of loans. When mortgage loans are sold, servicing rights are initially recorded at fair value and gains on sales of loans are recorded in the statement of operations. 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 servicing cost per loan, the discount rate, the escrow float rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. The Company compares the valuation model inputs and results to published industry data in order to validate the model results and assumptions. All classes of servicing assets are subsequently measured using the amortization method which requires servicing rights to be amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans.

Servicing assets are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is determined by stratifying rights into groupings based on predominant risk characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. If the Company later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the allowance may be recorded as an increase to income. Changes in valuation allowances are reported with amortization and impairment of servicing assets on the statement of operations. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses.

Servicing fee income that is reported on the statement of operations as loan servicing fees is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal; or a fixed amount per loan and are recorded as income when earned. Late fees and ancillary fees related to loan servicing are not material.

First mortgage loans serviced for others are not included in the accompanying consolidated statements of financial condition. The unpaid principal balances of these loans were $63.4 million and $76.2 million at December 31, 2019 and 2018, respectively. Custodial escrow balances maintained in connection with the foregoing loan servicing activities were $2.2 million and $1.8 million at December 31, 2019 and 2018, respectively. Capitalized mortgage servicing rights are included in other assets in the accompanying consolidated statements of financial condition. Servicing rights were $335,000 and $420,000 at December 31, 2019 and 2018, respectively, with no valuation allowance at December 31, 2019 and 2018.

Other Real Estate Owned ("OREO"): 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. 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 other real estate owned.

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.

On April 23, 2018, the Bank sold its office corporate office building in Burr Ridge, Illinois. A net gain of $93,000 was recorded in the second quarter of 2018 in connection with the sale.

Other Intangible Assets: Intangible assets acquired in a purchase business combination with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Core deposit intangible assets (“CDI”), are recognized at the time of acquisition based on valuations prepared by independent third parties or other estimates of fair value. In preparing such valuations, variables such as deposit servicing costs, attrition rates, and market discount rates are considered. CDI assets are amortized to expense over their useful lives. CDI were $41,000 and $102,000 at December 31, 2019 and 2018, respectively, and are included in other assets in the accompanying consolidated statements of financial condition.

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.

Long-Term Assets: Premises and equipment, core deposit and other intangible 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 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 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, 2019, the Company had a net deferred tax asset of $3.9 million.

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.

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 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 restricted stock shares.

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, 2019.

Restrictions on Cash: The Bank is required to maintain reserve balances in cash or on deposit with the Federal Reserve Bank, based on a percentage of deposits. As December 31, 2019 and 2018, the Bank has met the requirements.

The nature of the Company’s business requires that it maintain amounts with banks and federal funds sold which, at times, may exceed federally insured limits. Management monitors these correspondent relationships and the Company has not experienced any losses in such accounts.

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: 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 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.

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.

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.

Lease Accounting: The Company adopted FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”), including the adoption of the practical expedients, effective January 1, 2019. Lessees are required to recognize assets and liabilities on the balance sheet for leases with lease terms greater than 12 months. The Company recorded assets and liabilities of $6.7 million as a result of recording additional lease contracts where the Company is lessee. The Company did not restate comparative periods. The right of use assets are included in other assets and the lease obligations are included in other liabilities in the accompanying consolidated statements of financial condition.

Newly Issued Not Yet Effective Accounting Standards

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). These amendments require the measurement of 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 today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. For SEC filers who are smaller reporting companies, ASU 2016-13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022.

The Company evaluates marketable investment securities with significant declines in fair value on a quarterly basis to determine whether they should be considered other-than-temporarily impaired under current accounting guidance, which generally provides that if a marketable security is in an unrealized loss position, whether due to general market conditions or industry or issuer-specific factors, the holder of the securities must assess whether the impairment is other-than-temporary.

Certain collateralized mortgage obligations that the Company holds in its investment portfolio were in an unrealized loss position at December 31, 2019, but the unrealized loss was not considered significant under the Company’s impairment testing methodology. In addition, the Company does not intend to sell these securities, and it is not likely that the Company will be required to sell the securities before their anticipated recovery occurs.

The Bank, as a member of Visa USA, received 51,404 unrestricted shares of Visa, Inc. Class B common stock in connection with Visa, Inc.’s initial public offering in 2007 and a related retroactive responsibility plan. The retroactive responsibility plan obligates all former Visa USA members to indemnify Visa USA, in proportion to their equity interests in Visa USA, for certain litigation losses and expenses, including settlement expenses, for the lawsuits covered by the retrospective responsibility plan. Due to the restrictions that the retrospective responsibility plan imposes on the Company’s Visa, Inc. Class B shares, the Company had not recorded the Class B shares as an asset.

The Bank sold 25,702 shares of Visa Class B common stock in the fourth quarter of 2018 and recorded a gain of $3.6 million. For equity investments without readily determinable fair values, when an orderly transaction for the identical or similar investment of the same issuer is identified, we use the valuation techniques permitted under ASC 820 Fair Value to evaluate the observed transaction(s) and adjust the fair value of the equity investment.

Based on the existing transfer restriction and the uncertainty of the outcome of the Visa litigation mentioned above, the remaining 25,702 Visa Class B shares that the Company owned as of December 31, 2018 were carried at $3.4 million in other assets with a corresponding gain.

The Bank sold the remaining 25,702 shares of Visa Class B common stock in the first quarter of 2019 and recorded a gain of $295,000.

Loan Origination/Risk Management. The Company has certain lending policies and procedures in place that are designed to maximize loan income within an acceptable level of risk. The Company reviews and approves these policies and procedures on a periodic basis. A reporting system supplements the review process by providing management with frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies and nonperforming and potential problem loans via trend and risk rating migration. The Company requires title insurance insuring the priority of our lien on real estate collateral, fire and extended coverage casualty insurance, and, if appropriate, flood insurance, in order to protect our security interest in the underlying real property collateral.

The majority of the loans the Company originates are commercial-related loans, such as multi-family, nonresidential real estate, commercial, construction and land loans, and commercial leases. In addition, we originated one-to-four family residential mortgage loans and consumer loans until December 31, 2017. We also occasionally purchase and sell loan participations. The following briefly describes our principal loan products.

The Company originates real estate loans principally secured by first liens, both non-owner occupied and owner occupied commercial real estate. The non-owner occupied commercial real estate properties are predominantly multi-family apartment buildings, office buildings, light industrial buildings, shopping centers and mixed-use developments and, to a much lesser extent, more specialized properties such as nursing homes and other healthcare facilities.

Multi-family mortgage loans generally are secured by multi-family rental properties such as apartment buildings, including subsidized apartment units. In general, loan amounts range between $500,000 and $5.0 million at December 31, 2019. Approximately 57.0% of the collateral is located outside of our primary market area; however, we do not have a concentration in any single market in excess of 25% of our loan portfolio outside of our primary market area. In underwriting multi-family mortgage loans, the Company considers a number of factors, which include the projected net cash flow to the loan’s debt service requirement (generally requiring a minimum ratio of 120%), the age and condition of the collateral, the financial resources and income level of the borrower, the borrower’s experience in owning or managing similar properties and, proximity to diverse employment opportunities. Multi-family mortgage loans are generally originated in amounts up to 80% of the appraised value of the property securing the loan. Personal guarantees are usually obtained on multi-family mortgage loans if the borrower/property owner is a legal entity.

Loans secured by multi-family mortgages generally involve a greater degree of credit risk as a result of several factors, including the concentration of principal in a limited number of loans and borrowers, the effects 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 multi-family mortgages typically depends upon the successful operation of the related real estate property. If the cash flow from the project is reduced below acceptable thresholds, the borrower’s ability to repay the loan may be impaired.

The Company emphasizes nonresidential real estate loans with initial principal balances between $500,000 and $5.0 million. Substantially all of our nonresidential real estate loans are secured by properties located in our primary market area. The Company’s nonresidential real estate loans are generally written as three- or five-year adjustable-rate mortgages or mortgages with balloon maturities of three or five years. Amortization on these loans is typically based on 20- to 30-year schedules. The Company also originates some 15-year fixed-rate, fully amortizing loans.

In the underwriting of nonresidential real estate loans, the Company generally lends up to 80% of the property’s appraised value. Decisions to lend are based on the economic viability of the property as the primary source of repayment and the creditworthiness of the borrower. In evaluating a proposed commercial real estate loan, we emphasize the ratio of the property’s projected net cash flow to the loan’s debt service requirement (generally requiring a minimum ratio of 120%), computed after deduction for a vacancy factor and property expenses we deem appropriate. Personal guarantees are usually pursued and obtained from nonresidential real estate borrowers.

Nonresidential real estate loans generally carry higher interest rates and have shorter terms and typically involve larger loan balances concentrated with single borrowers or groups of related borrowers. In addition, the payment of loans secured by income-producing properties typically depends on the successful operation of the related real estate project and thus may be subject to a greater extent to adverse conditions in the real estate market and in the general economy.

The Company makes various types of secured and unsecured commercial loans to customers in our market area for the purpose of financing equipment acquisition, expansion, working capital and other general business purposes. The terms of these loans generally range from less than one year to five years. The loans are either negotiated on a fixed-rate basis or carry adjustable interest rates indexed to (i) a lending rate that is determined internally, or (ii) a short-term market rate index.

Commercial credit decisions are based upon our assessment of the borrower’s cash flow, proposed collateral, business and credit history and any additional positive or negative credit risk factors. The Company determines the borrower’s ability to repay in accordance with the proposed terms of the loans and we assess the risks involved. An evaluation is made of the borrower to determine character and capacity to manage. Personal guarantees of the principals are pursued and usually obtained. In addition to evaluating the loan borrower’s financial statements, we consider the adequacy of the primary and secondary sources of repayment for the loan. Independent reports of the borrower’s credit history supplement our analysis of the borrower’s creditworthiness and at times are supplemented with inquiries to other banks and trade investigations. Moreover, certain assets listed on personal financial statements are verified. Proposed collateral for a secured transaction also is analyzed to determine its marketability. Commercial business loans generally have higher interest rates because they have a higher risk of default since their repayment generally depends on the successful operation of the borrower’s business and the sufficiency of any collateral. Pricing of commercial loans is based primarily on the credit risk of the borrower, with due consideration given to borrowers with appropriate deposit relationships.

The Company also lends money to small and mid-size leasing companies for equipment financing leases. Generally, commercial leases are secured by an assignment by the leasing company of the lease payments and by a secured interest in the equipment being leased. In most cases, the lessee acknowledges our security interest in the leased equipment and agrees to send lease payments directly to us. Consequently, the Company underwrites lease loans by examining the creditworthiness of the lessee rather than the lessor. Lease loans generally are non-recourse to the leasing company.

Generally, the Company’s commercial leases are secured primarily by technology equipment, medical equipment, material handling equipment and other capital equipment. Lessees tend to be publicly-traded companies with investment-grade rated debt or companies that have not issued public debt and therefore do not have a public debt rating. Commercial leases to these entities have a maximum outstanding credit exposure of $20.0 million to any single entity. Typically, commercial leases to these lessees have a maximum maturity of five years and a maximum outstanding credit exposure of $10.0 million to any single entity. In addition, the Company will originate commercial leases to lessees with below investment-grade public debt ratings and have a maximum outstanding credit exposure of $10.0 million to any single entity. Lease loans are almost always fully amortizing, with fixed interest rates.

Although the Company does not actively originate construction and land loans presently, construction and land loans generally consist of land acquisition loans to help finance the purchase of land intended for further development, including single-family homes, multi-family housing and commercial income property, development loans to builders in our market area to finance improvements to real estate, consisting mostly of single-family subdivisions, typically to finance the cost of utilities, roads, sewers and other development costs.

Until December 31, 2017, the Company offered conforming and non-conforming, fixed-rate and adjustable-rate residential mortgage loans with maturities of up to 30 years and maximum loan amounts generally of up to $2.5 million. One-to-four family residential mortgage loans were generally underwritten according to Fannie Mae guidelines, and loans that conformed to such guidelines are referred to as “conforming loans.” Private mortgage insurance is required for first mortgage loans with loan-to-value ratios in excess of 80%.

The ability of the Company’s borrowers to repay their loans, and the value of the collateral securing such loans, could be adversely impacted by economic weakness in its local markets as a result of unemployment, declining real estate values, or increased residential, office, industrial and retail shopping vacancies due to changes in business conditions. This not only could result in the Company experiencing charge-offs and/or nonperforming assets, but also could necessitate an increase in the provision for loan losses. These events, if they were to recur, would have an adverse impact on the Company’s results of operations and its capital.

Nonaccrual loans and impaired loans are defined differently. Some loans may be included in both categories, and some may only be included in one category. Nonaccrual loans include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans.

The Company’s reserve for uncollected loan interest was $81,000 and $72,000 at December 31, 2019 and 2018, respectively. When a loan is on non-accrual status and the ultimate collectability of the total principal of an impaired loan is in doubt, all payments are applied to principal under the cost recovery method. Alternatively, when a loan is on non-accrual status but there is doubt concerning only the ultimate collectability of interest, contractual interest is credited to interest income only when received, under the cash basis method pursuant to the provisions of FASB ASC 310–10, as applicable. In all cases, the average balances are calculated based on the month–end balances of the financing receivables within the period reported pursuant to the provisions of FASB ASC 310–10, as applicable.

Troubled Debt Restructurings

The Company evaluates loan extensions or modifications in accordance with FASB ASC 310–40 with respect to the classification of the loan as a TDR. In general, if the Company grants a loan extension or modification to a borrower for other than an insignificant period of time that includes a below–market interest rate, principal forgiveness, payment forbearance or other concession intended to minimize the economic loss to the Company, the loan extension or loan modification is classified as a TDR. In cases where borrowers are granted new terms that provide for a reduction of either interest or principal then due and payable, management measures any impairment on the restructured loan in the same manner as for impaired loans as noted above.

The Company had no TDRs at December 31, 2019 and $17,000 of TDRs at 2018, with no specific valuation reserves allocated at December 31, 2018. The Company had no outstanding commitments to borrowers whose loans are classified as TDRs at December 31, 2018.

During the years ending December 31, 2019 and 2018, there were no loans modified and classified as TDRs. During the year ending December 31, 2018, there were no loans that subsequently defaulted within twelve months of their modification.

A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms.

To determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under the Company’s internal underwriting policy.

Credit Quality Indicators:

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, including current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans based on credit risk. This analysis includes non-homogeneous loans, such as commercial and commercial real estate loans. This analysis is performed on a monthly basis. The Company uses the following definitions for risk ratings:

Special Mention. A Special Mention asset has 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 institution’s credit position at some future date. Special Mention assets are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification.

Substandard. Loans categorized as substandard continue to accrue interest, but exhibit a well-defined weakness or weaknesses that may jeopardize the liquidation of the debt. The loans continue to accrue interest because they are well secured and collection of principal and interest is expected within a reasonable time. The risk rating guidance published by the Office of the Comptroller of the Currency clarifies that a loan with a well-defined weakness does not have to present a probability of default for the loan to be rated Substandard, and that an individual loan’s loss potential does not have to be distinct for the loan to be rated Substandard.

Nonaccrual. An asset classified Nonaccrual has all the weaknesses inherent in one classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered “Pass” rated loans.

As of December 31, 2019, and based on the most recent analysis performed, the risk category of loans by class of loans is as follows:

Other Real Estate Owned [Abstract]

Other Real Estate Owned

Real estate that is acquired through foreclosure or a deed in lieu of foreclosure is classified as OREO until it is sold. When real estate is acquired through foreclosure or by deed in lieu of foreclosure, it is recorded at its fair value, less the estimated costs of disposal. If the fair value of the property is less than the loan balance, the difference is charged against the allowance for loan losses.

The following represents the roll forward of OREO and the composition of OREO properties.

The Company maintains a collateral pledge agreement covering secured advances whereby the Company has agreed to keep on hand, free of all other pledges, liens, and encumbrances, specifically identified whole first mortgages on improved residential property not more than 90-days delinquent to secure advances from the FHLB. All of the Bank’s FHLB common stock is pledged as additional collateral for these advances. At December 31, 2019, $32.5 million and $406.0 million of first mortgage and multi-family mortgage loans, respectively, collateralized potential advances. At December 31, 2019, we had the ability to borrow an additional $367.7 million under our credit facilities with the FHLB. The Company also had available pre-approved overnight federal funds borrowing. At December 31, 2019 and 2018, there was no outstanding balance on these lines.

As of December 31, 2019 and 2018, the Company’s net deferred tax asset (“DTA”) was $3.9 million and $6.2 million, respectively.

A DTA valuation allowance is required under ASC 740 when the realization of a DTA is assessed and the assessment indicates that it is “more likely than not” (i.e., more than 50% likely) that all or a portion of the DTA will not be realized. All available evidence, both positive and negative must be considered to determine whether, based on the weight of that evidence, a valuation allowance against the net DTA is required. Objectively verifiable evidence is assigned greater weight than evidence that is not objectively verifiable. The valuation allowance is analyzed quarterly for changes affecting the DTA.

The Company’s ability to realize the DTA is dependent upon the generation of future taxable income during the periods in which the tax attributes underlying the DTA become deductible. The amount of the DTA that will ultimately be realized will be impacted by the Company’s future taxable income, any changes to the many variables that could impact future taxable income and the then applicable corporate tax rate. As of December 31, 2019 and 2018, management determined that it is more likely than not that the Company will be able to utilize the entire DTA.

At December 31, 2019, the Company had a federal net operating loss carryforward of $7.3 million relating to its acquisition of Downers Grove National Bank, which is subject to utilization limitations under Section 382 of the Internal Revenue Code, and will begin to expire in 2030, and $225,000 of alternative minimum tax credit carryforward that does not expire and is subject to utilization limitations under Section 382 of the Internal Revenue Code. At December 31, 2019, the Company had a state net operating loss carryforward for the State of Illinois of $50.1 million, which will begin to expire in 2023.

Regulatory Matters

REGULATORY MATTERS

The Bank is subject to regulatory capital requirements administered by the federal banking agencies. The capital adequacy guidelines and prompt corrective action regulations, involve the quantitative measurement of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. The failure to meet minimum capital requirements can result in regulatory actions. The final rules implementing Basel Committee on Banking Supervision's capital guidelines for U.S. banks (Basel III rules) became effective in 2015. The net unrealized gain or loss on available-for-sale securities is not included in computing regulatory capital.

In addition, as a result of the legislation, the federal banking agencies developed a “Community Bank Leverage Ratio” (the ratio of a bank’s tangible equity capital to average total consolidated assets) for financial institutions with assets of less than $10 billion. A “qualifying community bank” that exceeds this ratio will be deemed to be in compliance with all other capital and leverage requirements, including the capital requirements to be considered “well capitalized” under Prompt Corrective Action statutes. The federal banking agencies may consider a financial institution’s risk profile when evaluating whether it qualifies as a community bank for purposes of the capital ratio requirement. The federal banking agencies must set the minimum capital for the new Community Bank Leverage Ratio at not less than 8% and not more than 10%, and have established 9% as the minimum capital level, effective March 31, 2020. A financial institution can elect to be subject to this new definition.

Prompt corrective action regulations provide five classifications: well-capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If only adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required.

The minimum capital ratios set forth in the Regulatory Capital Plans will be increased and other minimum capital requirements will be established if and as necessary. In accordance with the Regulatory Capital Plans, the Bank will not pursue any acquisition or growth opportunity, declare any dividend or conduct any stock repurchase that would cause the Bank's total risk-based capital ratio and/or its Tier 1 leverage ratio to fall below the established minimum capital levels or the capital levels required for capital adequacy plus the CCB. The minimum CCB is 2.5%.

As of December 31, 2019, the Bank was well-capitalized, with all capital ratios exceeding the well-capitalized requirement. There are no conditions or events that management believes have changed the Bank’s prompt corrective action capitalization category.

The Bank is subject to regulatory restrictions on the amount of dividends it may declare and pay to the Company without prior regulatory approval, and to regulatory notification requirements for dividends that do not require prior regulatory approval.

Actual and required capital amounts and ratios for the Bank were:

EMPLOYEE BENEFIT PLANS

Employee Stock Ownership Plan ("ESOP"). On March 29, 2017, the ESOP was terminated and the ESOP repaid all amounts owing under the ESOP’s Term Loan Agreement with the Company (the “Share Acquisition Loan”). The ESOP repaid the Share Acquisition Loan by transferring 753,490 unallocated shares of the Company’s common stock to the Company in exchange for the full satisfaction of the Share Acquisition Loan, using the valuation method provided for in the ESOP. A total of 78,362 unallocated shares remained in the ESOP after the Share Acquisition Loan was repaid, and these shares were released and were allocated to the accounts of eligible ESOP participants who were actively employed by the Bank as of March 29, 2017, based on their account balances. These transactions resulted in the recording of one-time, non-cash, non-tax deductible equity compensation expense of $1.1 million in the first quarter of 2017. The Share Acquisition Loan had no outstanding principal balance at December 31, 2019 and 2018.

The Company made the Share Acquisition Loan to the ESOP in the original principal amount of $19.6 million in connection with the Company’s mutual to stock conversion in 2005. The proceeds of the Share Acquisition Loan were used by the ESOP to purchase 1,957,300 shares of the Company’s common stock issued in the subscription offering at a price of $10.00 per share. The Share Acquisition Loan was secured by a pledge of the acquired shares and the ESOP made annual loan payments with funds it received from the Bank’s discretionary contributions to the ESOP in subsequent years and dividends it received on unallocated shares. As loan payments were made, the Company recorded compensation expense based on the allocation of shares released.

Contributions to the ESOP were zero for the years ended December 31, 2019 and 2018. Expense related to the ESOP was zero for the years ended December 31, 2019 and 2018.

Shares held by the ESOP were as follows:



	December 31, 2018
Allocated to participants	885,896
Distributed to participants	(885,896	)
Total ESOP shares	—

Profit Sharing Plan/401(k) Plan. The Company has a defined contribution plan (“profit sharing plan”) covering all of its eligible employees. Employees are eligible to participate in the profit sharing plan after attainment of age 21 and completion of one year of service. The Company provides a match of $0.50 on each $1.00 of contribution up to 6% of eligible compensation beginning April 1, 2007. The Company may also contribute an additional amount annually at the discretion of the Board of Directors. Contributions totaling $320,000 and $506,000 were made for the years ended December 31, 2019 and 2018, respectively.

EQUITY INCENTIVE PLANS

On June 27, 2006, the Company’s stockholders approved the BankFinancial Corporation 2006 Equity Incentive Plan, which authorized the Human Resources Committee of the Board of Directors of the Company to grant a variety of cash- and equity-based incentive awards, including stock options, stock appreciation rights, restricted stock, performance shares and other incentive awards, to employees and directors aggregating up to 3,425,275 shares of the Company’s common stock. The Plan provided that no awards may be granted under the Plan after the ten-year anniversary of the Effective Date. Consequently, no further awards will be granted under this Plan.

Restricted stock awards generally vested annually over varying periods from three to five years and vesting was subject to acceleration in certain circumstances. All remaining restricted stock awards vested or were forfeited during 2018. The Company recognized zero expense relating to the grant of shares of restricted stock during the years ended December 31, 2019 and 2018. No further shares of restricted stock will be granted.

Commitments and Contingencies Disclosure [Abstract]

Loan Commitments and Other Off-Balance Sheet Activities

The Company is party to various financial instruments with off-balance-sheet risk. The Company uses these financial instruments in the normal course of business to meet the financing needs of customers and to effectively manage exposure to interest rate risk. These financial instruments include commitments to extend credit, standby letters of credit, unused lines of credit, and commitments to sell loans. When viewed in terms of the maximum exposure, those instruments may involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated statements of financial condition. Credit risk is the possibility that a counterparty to a financial instrument will be unable to perform its contractual obligations. Interest rate risk is the possibility that, due to changes in economic conditions, the Company’s net interest income will be adversely affected.

The following is a summary of the contractual or notional amount of each significant class of off-balance-sheet financial instruments outstanding. The Company’s exposure to credit loss in the event of nonperformance by the counterparty for commitments to extend credit, standby letters of credit, and unused lines of credit is represented by the contractual notional amount of these instruments.

The contractual or notional amounts are as follows:



	December 31,
	2019		2018
Financial instruments wherein contractual amounts represent credit risk
Commitments to extend credit	$	19,737	$	75,180
Standby letters of credit	6,119		5,965
Unused lines of credit	149,771		152,554

Commitments to extend credit are generally made for periods of 60 days or less. The fixed-rate loans commitment totaled $11.9 million with interest rates ranging from 3.15% to 5.25% and maturities ranging from 1 to 30 years.

Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if it is deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the customers.

Fair Value Disclosures [Abstract]

Fair Value

FAIR VALUE

Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values:


•	Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date.


•	Level 2 – Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.


•	Level 3 – Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.

The Company used the following methods and significant assumptions to estimate the fair value of each type of financial instrument:

Securities: The fair values of debt securities are generally determined by matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities, but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2).

Other investments: Other investments includes our investments in equity securities without readily determinable fair values. Equity investments without readily determinable fair values, includes our Visa Class B shares, which are categorized as Level 3. Our Visa Class B ownership includes shares acquired at no cost from our prior participation in Visa’s network while Visa operated as a cooperative.

Impaired Loans: The fair value of impaired loans with specific allocations of the allowance for loan losses is generally based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available for similar loans and collateral underlying such loans. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted in accordance with the allowance policy.

Other Real Estate Owned: Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. Fair value is commonly based on recent real estate appraisals which are updated no less frequently than annually. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach with data from comparable properties. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Real estate owned properties are evaluated on a quarterly basis for additional impairment and adjusted accordingly.

The following table sets forth the Company’s financial assets that were accounted for at fair value and are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

At December 31, 2019 there were no impaired loans that were measured for impairment using the fair value of the collateral for collateral–dependent loans and which had specific valuation allowances. At December 31, 2018 there was one nonresidential impaired loan with a carrying value of $270,000 and a valuation allowance of $27,000 that was measured for impairment using the fair value of the collateral for collateral–dependent loans and which had a specific valuation allowance.

At December 31, 2019 there were no OREO properties with valuation allowances, compared to OREO land carried at the lower of cost or fair value less costs to sell, with a carrying value of $24,000 less a valuation allowance of $23,000, or $1,000, at December 31, 2018.

Loans: The exit price observations are obtained from an independent third-party using its proprietary valuation model and methodology and may not reflect actual or prospective market valuations. The valuation is based on the probability of default, loss given default, recovery delay, prepayment, and discount rate assumptions.

While the above estimates are based on management’s judgment of the most appropriate factors, as of the balance sheet date, there is no assurance that the estimated fair values would have been realized if the assets were disposed of or the liabilities settled at that date, since market values may differ depending on the various circumstances. The estimated fair values would also not apply to subsequent dates.

In addition, other assets and liabilities that are not financial instruments, such as premises and equipment, are not included in the above disclosures.

(1)	Not within the scope of ASC 606

A description of the Company's revenue streams accounted for under ASC 606 follows:

Deposit service charges and fees: The Company earns fees from its deposit customers based on specific types of transactions, account maintenance and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer's request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer's account balance.

Interchange income: The Company earns interchange fees from debit cardholder transactions conducted through the Visa payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. Interchange income is included in deposit service charges and fees. Interchange income for the years ended December 31, 2019 and 2018 was $1.5 million.

Gain on sale of premises held-for-sale: On April 23, 2018, the Bank sold its office building in Burr Ridge, Illinois. The sale was to an unrelated party and title was transferred at closing. As such, the transaction constituted a sale and a net gain was recorded in the second quarter of 2018.

Trust and insurance commissions and annuities income: The Company earns trust, insurance commissions and annuities income from its contracts with trust customers to manage assets for investment, and/or to transact on their accounts. These fees are primarily earned over time as the Company provides the contracted monthly or quarterly services and are generally assessed based on a tiered scale of the market value of assets under management (AUM) at month-end. Fees that are transaction based, including trade execution services, are recognized at the point in time that the transaction is executed, i.e., the trade date.

Gains/losses on sales of OREO and other assets: The Company records a gain or loss from the sale of OREO and other assets when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the Company finances the sale of OREO to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain (loss) on sale if a significant financing component is present. OREO sales for the years ended December 31, 2019 and 2018 were not financed by the Company.

Allowance for Loan Losses


•	specific allowances established for any impaired residential non-owner occupied mortgage, multi-family mortgage, nonresidential real estate, construction and land, commercial, and commercial lease loans for which the recorded investment in the loan exceeds the measured value of the loan; and


•	general allowances for loan losses for each loan class based on historical loan loss experience; and adjustments to historical loss experience (general allowances), maintained to cover uncertainties that affect our estimate of probable incurred credit losses for each loan class.

Uncollected Interest

When a loan is on non-accrual status and the ultimate collectability of the total principal of an impaired loan is in doubt, all payments are applied to principal under the cost recovery method. Alternatively, when a loan is on non-accrual status but there is doubt concerning only the ultimate collectability of interest, contractual interest is credited to interest income only when received, under the cash basis method pursuant to the provisions of FASB ASC 310–10, as applicable. In all cases, the average balances are calculated based on the month–end balances of the financing receivables within the period reported pursuant to the provisions of FASB ASC 310–10, as applicable.
