Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	NOTE 2 - Summary of Significant Accounting Policies Organization From October 2017 until January 2020, as discussed below, we operated in a two-tier mutual holding company structure. The predecessor FFBW, Inc. (“Old FFBW”) was a federal corporation that was the publicly traded stock holding company of First Federal Bank of Wisconsin (the “Bank”). At December 31, 2019, Old FFBW had 7,702,478 shares of common stock outstanding, of which 3,436,424 shares, or 44.6%, were owned by the public, including 29,325 shares owned by FFBW Community Foundation, and the remaining 4,266,054 shares were held by FFBW, MHC (the “MHC”), a federally chartered mutual holding company and former parent company of Old FFBW. ​ The Bank is a community bank headquartered in Waukesha, Wisconsin that provides financial services to individuals and businesses from our offices in Waukesha, Brookfield, and the South Side of Milwaukee. ​ FFBW, Inc. (the “Company”) is a Maryland corporation that was organized in September 2019 to be the successor to Old FFBW and be the savings and loan holding company for the Bank upon completion of the second step mutual-to-stock conversion (the “Conversion”) of the MHC. Prior to completion of the Conversion, approximately 55.4% of the shares of common stock of the Company were owned by the MHC. The Conversion was completed on January 16, 2020. In the Conversion, the Company sold 4,268,570 shares of common stock at $10.00 per share, for net proceeds of approximately $37.9 million (including the purchase of 341,485 ESOP shares), and issued 3,436,430 shares of common stock in exchange for the shares of Old FFBW common stock owned by Old FFBW stockholders, other than the MHC, as of the effective date of the conversion. As a result of the conversion, the MHC and Old FFBW ceased to exist. The Conversion was conducted pursuant to the MHC’s Plan of Conversion. The Plan of Conversion provided for the establishment, upon the completion of the Conversion, of special “liquidation accounts” for the benefit of certain depositors of the Bank in an amount equal to the MHC’s ownership interest in the stockholders’ equity of Old FFBW as of the date of the latest balance sheet contained in the prospectus plus the MHC’s net assets (excluding its ownership of Old FFBW). Following the completion of the Conversion, the Company and the Bank are not permitted to pay dividends on their capital stock if the Company’s shareholder’s equity, or the shareholder's equity of the Bank, would be reduced below the amount of the liquidation accounts. The liquidation accounts are reduced annually to the extent that eligible account holders have reduced their qualifying deposits. Subsequent increases in these accounts will not restore an eligible account holder's interest in the liquidation accounts. Direct costs of the Conversion and public offering, totaling approximately $1.2 million, were applied against the proceeds from the shares sold in the public offering. ​ Use of Estimates In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the fair values of securities, fair value of financial instruments, the valuation of other real estate owned and the valuation of deferred income tax assets. Revenue Recognition ​ Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers ("ASC 606"), establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity's contracts to provide goods or services to customers. The core principle requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those goods or services recognized as performance obligations are satisfied. ​ The majority of the Company's revenue-generating transactions are not subject to ASC 606, including all interest and dividend income generated from financial instruments. Certain noninterest income items, including loan servicing income, gain on sales of loans, gain on sales of securities, and other noninterest income have been evaluated and were determined to not fall within the scope of ASC 606. Elements of noninterest income that are within the scope of ASC 606, are as follows: ​ Service charges and other fees - The Company earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Management reviewed the deposit account agreements and determined that the agreements can be terminated at any time by either the Company or the account holder. Transaction fees, such as balance transfers, wires and overdraft charges are settled the day the performance obligation is satisfied. The Company's monthly service charges and maintenance fees are for services provided to the customer on a monthly basis and are considered a series of services that have the same pattern of transfer each month. The review of service charges assessed on deposit accounts included the amount of variable consideration that is a part of the monthly charges. It was found that the waiver of service charges due to insufficient funds and dormant account fees is immaterial and would not require a change in the accounting treatment for these fees under the new revenue standards. ​ Interchange fees - Customers use a Bank-issued debit card to purchase goods and services, and the Company earns interchange fees on those transactions, typically a percentage of the sale amount of the transaction. The Company records the amount due when it receives the settlement from the payment network. Payments from the payment network are received and recorded into income on a daily basis. These fees are included in “service charges and other fees” on the Consolidated Statements of Operations. There are no contingent debit card interchange fees recorded by the Company that could be subject to a clawback in future periods. ​ Cash and Cash Equivalents For purposes of reporting cash flows, cash and cash equivalents include cash and balances due from banks, non-maturity deposits in the Federal Home Loan Bank of Chicago (FHLB), and fed funds sold. The Company has not experienced any losses in such accounts. ​ Available for Sale Securities Securities classified as available for sale are those securities that the Company intends to hold for an indefinite period of time, but not necessarily to maturity. Any decision to sell a security classified as available for sale would be based on various factors, including significant movements in interest rates, changes in the maturity mix of the Company’s assets and liabilities, liquidity needs, regulatory capital requirements, and other similar factors. Securities classified as available for sale are carried at fair value. Unrealized gains or losses are reported as increases or decreases in other comprehensive income, net of the related deferred tax effect. Realized gains or losses, determined on the basis of the cost of specific securities sold, are included in earnings. Gains and losses on the sale of securities are recorded on the trade date and determined using the specific-identification method. ​ Declines in fair value of securities that are deemed to be other than temporary, if applicable, are reflected in earnings as realized losses. In estimating other-than-temporary impairment losses, management considers the length of time and the extent to which fair value has been less than cost, the financial condition and near-term prospects of the issuer, and the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient enough to allow for any anticipated recovery in fair value. ​ Loans Acquired in a Transfer The Company acquires loans (including debt securities) individually and in groups or portfolios. These loans are initially measured at fair value with no allowance for loan losses. The Company’s allowance for loan losses on all acquired loans reflect only those losses incurred subsequent to acquisition. Certain acquired loans may have experienced deterioration of credit quality between origination and the Company’s acquisition of the loans. At acquisition, the Company reviews each loan to determine whether there is evidence of deterioration of credit quality since origination and if it is probable that the Company will be unable to collect all amounts due according to the loan’s contractual terms. If both conditions exist, the Company determines whether each such loan is to be accounted for individually or whether such loans will be assembled into pools of loans based on common risk characteristics (for example, credit score, loan type, and date of origination). The Company considers expected prepayments and estimates the amount and timing of undiscounted principal, interest, and other cash flows expected at acquisition for each loan and aggregated pool of loans. The excess of the loan’s or pool’s scheduled contractual principal and interest payments over all cash flows expected at acquisition is calculated as the nonaccretable difference. The excess of cash flows expected to be collected over the fair value of each loan or pool (accretable yield) is accreted into interest income over the remaining life of the loan or pool. At each reporting date, the Company continues to estimate cash flows expected to be collected for each loan or pool. If expected cash flows have decreased from the acquisition date estimate, the Company recognizes an allowance for loan losses. If expected cash flows have increased from the acquisition date estimate, the Company increases the amount of accretable yield to be recognized as interest income over the remaining life of the loan or pool. Loans Held for Sale Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value in the aggregate. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. Mortgage loans held for sale are sold with the mortgage servicing rights released by the Company. Gains or losses on sales of mortgage loans are recognized based on the difference between the selling price and the carrying value of the related mortgage loan sold. Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff generally are reported at their outstanding unpaid principal balances adjusted for deferred loan fees and costs, charge-offs, and an allowance for loan losses. Interest on loans is accrued and credited to income based on the unpaid principal balance. Loan-origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method. The accrual of interest on loans is discontinued when, in the opinion of management, there is an indication that the borrower may be unable to make payments as they become due. When loans are placed on nonaccrual status or charged off, all unpaid accrued interest is reversed against interest income. The interest on these loans is subsequently accounted for on the cash-basis or cost-recovery method until qualifying for return to accrual status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Allowance for Loan Losses The allowance for loan losses is maintained at the level considered adequate by management to provide for losses that are probable as of the balance sheet date. The allowance for loan losses is established through a provision for loan losses charged to expense as losses are estimated to have occurred. Loan losses are charged against the allowance when management believes that the collectability of the principal is unlikely. Subsequent recoveries, if any, are credited to the allowance. In determining the adequacy of the allowance balance, the Company makes evaluations of the loan portfolio and related off-balance sheet commitments, considers current economic conditions and historical loss experience, and reviews specific problem loans and other factors. When establishing the allowance for loan losses, management categorizes loans into risk categories generally based on the nature of the collateral and the basis of repayment. These risk categories and their relevant risk characteristics are as follows: Commercial development: Commercial real estate: Commercial and industrial: One-to-four family owner-occupied: One-to-four family investor-owned: Multifamily real estate: Consumer: Management regularly evaluates the allowance for loan losses using the Company’s past loan loss experience, known and inherent risks in the loan portfolio, composition of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, current economic conditions, and other relevant factors. This evaluation is inherently subjective since it requires material estimates that may be susceptible to significant change. A loan is impaired when, based on current information, it is probable that the Company will not collect all amounts due in accordance with the contractual terms of the loan agreement. Management determines whether a loan is impaired on a case-by-case basis, taking into consideration the payment status, collateral value, length and reason of any payment delays, the borrower’s prior payment record, and any other relevant factors. Large groups of smaller-balance homogeneous loans, such as residential mortgage and consumer loans, are collectively evaluated in the allowance for loan losses analysis and are not subject to impairment analysis unless such loans have been subject to a restructuring agreement. Specific allowances for impaired loans are based on discounted cash flows of expected future payments using the loan’s initial effective interest rate or the fair value of the collateral if the loan is collateral dependent. In addition, various regulatory agencies periodically review the allowance for loan losses. These agencies may require the Company to make additions to the allowance for loan losses based on their judgments of collectability based on information available to them at the time of their examination. Troubled Debt Restructurings Loans are accounted for as troubled debt restructurings when a borrower is experiencing financial difficulties that lead to a restructuring of the loan and the Company grants a “concession” to the borrower that they would not otherwise consider. These concessions include a modification of terms, such as a reduction of the stated interest rate or loan balance, a reduction of accrued interest, an extension of the maturity date at an interest rate lower than a current market rate for a new loan with similar risk, or some combination thereof to facilitate repayment. Troubled debt restructurings are considered impaired loans. Foreclosed Assets Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value, less costs to sell, at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less costs to sell. Revenue and expenses from operations and changes in the valuation allowance are included in net expenses from foreclosed assets. Premises and Equipment Depreciable assets are stated at cost less accumulated depreciation. Provisions for depreciation are computed on straight-line and accelerated methods over the estimated useful lives of the assets. Other Equity Investments ​ Other Equity Investments consist of Federal Home Loan Bank of Chicago (“FHLB”) stock and Bankers’ Bank stock. The value. The Company is required to hold the stock as a member of the FHLB and transfer of the stock is substantially restricted. The stock is evaluated for impairment on an annual basis. The Company is required to Income Taxes ​ Amounts provided for income tax expense are based on income reported for financial statement purposes and do not necessarily represent amounts currently payable under tax laws. Deferred income tax assets and liabilities are computed annually for differences between the financial statement and income tax basis of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. As changes in tax laws or rates are enacted, deferred income tax assets and liabilities are adjusted through the provision for income taxes. The differences relate principally to the allowances for loan losses, deferred compensation, depreciation, FHLB stock dividends and non-accrual interest. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. The tax effects from an uncertain tax position can be recognized in the financial statements only if the position is more likely than not to be sustained on audit, based on the technical merits of the position. The Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more likely than not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. Based on its evaluation, the Company has concluded that there are no significant uncertain tax positions requiring recognition in its financial statements. The Company’s policy is to recognize interest and penalties related to income tax issues as components of income tax expense. During the periods shown, the Company did not recognize any interest or penalties related to income tax expense in its statements of operations. Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Advertising Advertising costs are expensed as incurred. Other Comprehensive Income (Loss) Other comprehensive income (loss) is shown on the statements of comprehensive income. The Company’s accumulated other comprehensive income (loss) is composed of the unrealized gains (losses) on securities available for sale, net of tax and is shown on the statements of changes in equity. Reclassification adjustments out of other comprehensive income (loss) for losses realized on sales of securities available for sale comprise the entire balance of “net gain on sale of securities” on the statements of operations. Off-Balance Sheet Financial Instruments In the ordinary course of business, the Company has entered into off-balance-sheet financial instruments consisting of commitments to extend credit, unfunded commitments under lines of credit, and standby letters of credit. Such financial instruments are recorded in the financial statements when they become payable. Life Insurance The Company has purchased life insurance policies on certain key members of the management team. Life insurance is measured at the amount that could be realized under the insurance contract as of the balance sheet date, which is generally the cash surrender value of the policy. Recent Accounting Pronouncements The Company qualifies as an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). For as long as the Company is an emerging growth company, it may choose to take advantage of exemptions from various reporting requirements applicable to other public companies. An emerging growth company may elect to use the extended transition period to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies, but must make such election when the Company is first required to file a registration statement. The Company has elected to use the extended transition period described above and intends to maintain its emerging growth company status as allowed under the JOBS Act. The following ASUs have been issued by the FASB and may impact the Company's financial statements in future reporting periods: ​ ASU No. 2016-13, “Credit Losses (Topic 326).” ASU No. 2019-04, “Codification Improvements to Topic 326.” ASU No. 2019-05, “Financial Instruments-Credit Losses.” ​ ASU 2016-13 requires organizations to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Early adoption will be permitted for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is currently assessing the impact of adopting ASU 2016-13 on its financial statements. ​ ​ ASU No. 2016-02, “Leases (Topic 842): Amendments to the Leases Analysis.” ASU No. 2018-10, "Codification Improvements to Topic 842." ASU No. 2018-11, "Targeted Improvements" ​ For lessees, Topic 842 requires leases to be recognized on the balance sheet, along with disclosure of key information about leasing arrangements. Topic 842 was subsequently amended by ASU 2018-01, 2018-10 and 2018-11. The new standard establishes a right-of-use (ROU) model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification expense recognition in the income statement. ​ For lessors, Topic 842 requires lessors to classify leases as sales-type, direct financing or operating leases. A lease is a sales-type lease if any one of five criteria are met, each of which indicate that the lease, in effect, transfers control of the underlying asset to the lessee. If none of those five criteria are met, but two additional criteria are both met, indicating the lessor has transferred substantially all the risks and benefits of the underlying asset to the lessee and a third party, the lease is a direct financing lease. All leases that are not sales-type or direct financing leases are operating leases. ​ The new standard is effective for the Company on January 1, 2022, with early adoption permitted. A modified retrospective transition approach is required, applying the new standard to all leases existing at the date of initial application. An entity may choose to use either (1) the new standard's effective date or (2) the beginning of the earliest comparative period presented in the financial statements as its date of initial application. The Company expects to adopt the new standard on January 1, 2022 using the effective date as its date of initial application. The Company is expecting to record a right of use asset and corresponding lease obligation for its outstanding leases. ​

Earnings per share
Earnings Per Share	NOTE 3 – Earnings Per Share Basic earnings per common share is computed by dividing net income by the weighted average number of common shares outstanding, adjusted for weighted average unallocated ESOP shares, during the applicable period, excluding outstanding participating securities. Participating securities include non-vested restricted stock awards and restricted stock units, though no actual shares of common stock related to restricted stock units are issued until the settlement of such units, to the extent holders of these securities receive non-forfeitable dividends or dividend equivalents at the same rate as holders of the Company’s common stock. Diluted earnings per share is computed using the weighted-average number of shares determined for the basic earnings per common share computation plus the dilutive effect of stock compensation using the treasury stock method. Antidilutive options are disregarded in earnings per share calculations. ​ The following table presents the earnings per share calculations for the three and nine months ended September 30: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended Nine months ended ​ ​ ​ September 30, ​ September 30, ​ ​ ​ 2021 2020 2021 2020 ​ Net income ​ $ 459 ​ $ 484 ​ $ 1,581 ​ $ 1,327 ​ Basic potential common shares ​ ​ ​ ​ ​ ​ Weighted average shares outstanding ​ 6,912,234 ​ 7,707,375 ​ 7,182,779 ​ 7,706,025 ​ Weighted average unallocated Employee Stock Ownership Plan Shares ​ (560,767) ​ (591,355) ​ (569,689) ​ (600,277) ​ Basic weighted average shares outstanding ​ 6,351,467 ​ 7,116,020 ​ 6,613,090 ​ 7,105,748 ​ Dilutive potential common shares ​ 22,535 ​ — ​ 15,713 ​ 83 ​ Dilutive weighted average shares outstanding ​ 6,374,002 ​ 7,116,020 ​ 6,628,803 ​ 7,105,831 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Basic earnings per share ​ $ 0.07 ​ $ 0.07 ​ $ 0.24 ​ $ 0.19 ​ Diluted earnings per share ​ $ 0.07 ​ $ 0.07 ​ $ 0.24 ​ $ 0.19 ​ ​

At December 31, 2020, the investment portfolio included 4 securities available for sale, which had been in an unrealized loss position for greater than twelve months, and 13 securities available for sale, which had been in an unrealized loss position for less than twelve months. Because these securities have a fixed interest rate, their fair value is sensitive to movements in market interest rates. These unrealized losses are considered temporary because the Company does not currently have the intent to sell the securities before recovery of the losses; therefore we expect to collect all contractually due amounts from these securities. Accordingly, these investments were reduced to their fair values through accumulated other comprehensive income, not through earnings. ​ We regularly assess our securities portfolio for other than temporary impairment (“OTTI”). These assessments are based on the nature of the securities, the underlying collateral, the financial condition of the issuer, the extent and duration of the loss, our intent related to the individual securities, and the likelihood that we will have to sell securities prior to expected recovery. We did not have any impairment losses recognized in earnings for the three and nine months ended September 30, 2021 or September 30, 2020. ​ The amortized cost and fair value of available for sale securities by contractual maturity are shown below. Expected maturities will differ from contractual maturities in mortgage-backed securities since the anticipated maturities are not readily determinable.

The credit quality indicators monitored differ depending on the class of loan. Commercial loans and one-to-four family investor-owned and multifamily loans are generally evaluated using the following internally prepared ratings: “Pass” ratings are assigned to loans with adequate collateral and debt service ability such that collectability of the contractual loan payments is highly probable. “Special mention” ratings are assigned to loans where management has some concern that the collateral or debt service ability may not be adequate, though the collectability of the contractual loan payments is still probable. “Substandard” ratings are assigned to loans that do not have adequate collateral and/or debt service ability such that collectability of the contractual loan payments is no longer probable. “Doubtful” ratings are assigned to loans that do not have adequate collateral and/or debt service ability, and collectability of the contractual loan payments is unlikely.

When, for economic or legal reasons related to the borrower’s financial difficulties, the Company grants a concession to the borrower that the Company would not otherwise consider, the modified loan is classified as a troubled debt restructuring. Loan modifications may consist of forgiveness of interest and/or principal, a reduction of the interest rate, allowing interest-only payments for a period of time, and/or extending amortization terms. During the nine months ended and as of September 30, 2021, there was one commercial real estate loan totaling $116 and one 1-4 family owner-occupied loan totaling $115 that were new troubled debt restructurings. No troubled debt restructurings defaulted within 12 months of their modification date during the nine months ended September 30, 2021. During the year ended and as of December 31, 2020, there were no new troubled debt restructurings. No troubled debt restructurings defaulted within 12 months of their modifications during the year ended December 31, 2020. During April 2020, the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”) was signed into law which provides optional, temporary relief from accounting for certain pandemic-related loan modifications as a TDR. During 2020, the Bank offered payment deferrals to loan customers that were excluded from TDR classification based on the CARES Act. There were no loans remaining on a modified status as of September 30, 2021. Management regularly monitors impaired loan relationships. In the event facts and circumstances change, an additional provision for loan losses may be necessary. ​

The Company has a master contract agreement with the FHLB that provides for a borrowing up to the lesser of a determined multiple of FHLB stock owned or a determined percentage of the book value of the Company’s qualifying one-to-four family, multifamily, commercial real estate and commercial business loans. The Company pledged approximately $154,650 and $149,304 of one-to-four family, multifamily, commercial real estate and commercial business loans to secure FHLB advances at September 30, 2021 and December 31, 2020, respectively. FHLB provides both fixed and floating rate advances. Floating rates are tied to short-term market rates of interest, such as Federal funds, FHLB discount note or prime rates. Fixed rate advances are priced in reference to market rates of interest at the time of the advance, namely the rates that FHLB pays to borrowers at various maturities. Certain FHLB advances are subject to a prepayment penalty if they are repaid prior to maturity. FHLB advances are also secured by $851 and $825 of FHLB stock owned by the Company at September 30, 2021 and December 31, 2020, respectively. At September 30, 2021, the Company’s available and unused portion of this borrowing agreement based on the amount of FHLB stock was $16,014. In addition, the Company has a $7,000 federal funds line of credit through Bankers’ Bank of Wisconsin, which was not drawn on as of September 30, 2021. The Company also has the authority to borrow through the Federal Reserve’s Discount Window

Employee Stock Ownership Plan
Employee Stock Ownership Plan	NOTE 8 – Employee Stock Ownership Plan The Company maintains a leveraged employee stock ownership plan (“ESOP”) that covers substantially all employees. The ESOP was established in conjunction with Old FFBW’s initial stock offering completed in October 2017 and operates on a plan year ending December 31. The loan to fund the acquisition of stock by the ESOP was made by Old FFBW. Additional shares were purchased by the ESOP in conjunction with the Company’s stock offering completed in January 2020, which was financed by a loan from the Company. The Bank makes annual contributions to the ESOP equal to the ESOP’s debt service. The ESOP shares initially were pledged as collateral for this debt. As the debt is repaid, shares are released from collateral and allocated to active participants, based on the proportion of debt service paid in the year. Because the debt is intercompany, it is eliminated in consolidation for presentation in these financial statements. The shares pledged as collateral are reported as unearned ESOP shares in the balance sheet. As shares are committed to be released from collateral and allocated to active participants, the Company reports compensation expense equal to the current market price of the shares and the shares will become outstanding for earnings-per-shares (EPS) computations. During the nine months ended September 30, 2021 and 2020, 22,941 and 22,941 shares were committed to be released, respectively. During the nine months ended September 30, 2021 the average fair value per share of stock was $11.20 resulting in total ESOP compensation expense of $257 for the nine months ended September 30, 2021. During the nine months ended September 30, 2020 the average fair value per share of stock was $8.63 resulting in total ESOP compensation expense of $195 for the nine months ended September 30, 2020. The ESOP shares as of September 30, 2021 and December 31, 2020 were as follows: ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2021 December 31, 2020 Shares allocated to active participants ​ 62,305 ​ 33,861 Shares committed to be released and allocated to participants ​ 22,941 ​ 30,584 Shares distributed ​ ​ — ​ ​ (2,140) Total unallocated shares ​ 558,152 ​ 581,093 Total ESOP shares ​ 643,398 ​ 643,398 Fair value of unallocated shares (based on $12.04 and $10.02 share price at September 30, 2021 and December 31, 2020, respectively) ​ $ 6,720 ​ $ 5,823 ​

Share-based Compensation Plans	NOTE 9 - Share-based Compensation Plans The Company adopted the FFBW, Inc. 2018 Equity Incentive Plan in 2018. In May 2021 the Company adopted the FFBW, Inc. 2021 Equity Incentive Plan. ASC Topic 718 requires that the grant date fair value of equity awards to employees and directors be recognized as compensation expense over the period during which they are required to provide service in exchange for such awards. The following table summarizes the impact of the Company’s share-based payment plans in the financial statements for the period shown: ​ ​ ​ ​ ​ ​ ​ Nine Months Ended ​ September 30, ​ 2021 2020 Total cost of stock grant plan during the year $ 173 ​ $ 154 Total cost of stock option plan during the year 127 ​ 119 Total cost of share-based payment plans during the year $ 300 ​ $ 273 ​ ​ ​ ​ ​ ​ Amount of related income tax benefit recognized in income $ 71 ​ $ 74 ​ ​ Options are granted with an exercise price equal to no less than the market price of the Company’s shares at the date of grant: those option awards generally vest pro-rata over five years of service and have 10-year . In 2021, 4,000 restricted shares were granted to directors under the 2021 plan. Share amounts related to periods prior to the date of the closing of the Offering on January 16, 2020 have been restated to give retroactive recognition to the 1.1730 exchange ratio applied in the offering. ​ The following table summarizes stock options activity for the nine months ended September 30, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Outstanding ​ ​ ​ ​ ​ ​ ​ Weighted ​ ​ ​ ​ ​ ​ ​ Weighted ​ Average ​ ​ ​ ​ ​ ​ ​ Average ​ Remaining ​ Aggregate ​ ​ ​ Stock Option ​ Exercise ​ Contractual ​ Intrinsic ​ ​ Awards ​ Price ​ Term (years) ​ Value Options outstanding as of December 31, 2020 269,220 ​ $ 10.51 ​ ​ ​ ​ ​ ​ Granted 76,000 ​ 11.27 ​ ​ ​ ​ ​ ​ Exercised (6,692) ​ 10.18 ​ ​ ​ ​ ​ ​ Expired or cancelled ​ (2,346) ​ ​ 10.64 ​ ​ ​ ​ ​ ​ Forfeited (19,057) ​ 10.01 ​ ​ ​ ​ ​ ​ Options outstanding as of September 30, 2021 317,125 ​ $ 10.73 7.98 ​ $ 320,559 ​ Options exercisable as of September 30, 2021 126,770 ​ $ 10.71 ​ 7.31 ​ $ 128,851 ​ ​ The fair value of each option award is estimated on the date of grant using the Black-Scholes option pricing model based on certain assumptions. Since the Company does not have sufficient historical fair value estimates of its stock, the Company calculates expected volatility using the historical volatility of the Dow Jones U.S. Financial Services Index. The risk-free interest rate for periods within the contractual term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The expected life of options is estimated based on the assumption that options will be exercised evenly throughout their life after vesting and represents the period of time that options granted are expected to remain outstanding. There were no options granted during the three months ended September 30, 2021. The following is a summary of changes in restricted shares for the nine months ended September 30, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted ​ ​ ​ ​ Average ​ ​ Number of ​ Grant Date Fair ​ ​ Shares Value Nonvested stock awards as of December 31, 2020 ​ 62,060 ​ $ 10.73 Granted ​ 22,750 ​ ​ 11.35 Vested ​ (19,561) ​ ​ 10.77 Forfeited (5,519) ​ 10.08 Nonvested stock awards as of September 30, 2021 59,730 ​ $ 11.02 ​ As of September 30, 2021, there was $1.2 million of total unrecognized compensation cost related to non-vested share-based compensation arrangements (including share option and non-vested share awards) granted under the Company’s equity incentive plans. At September 30, 2021, the weighted-average period over which the unrecognized compensation expense is expected to be recognized was approximately 3.2 years.

Equity and Regulatory Matters
Equity and Regulatory Matters	​ NOTE 10 – Equity and Regulatory Matters The Bank is subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the table below) of Common Equity Tier 1, Tier 1, and Total capital to risk-weighted assets and of Tier 1 capital to average assets. It is management’s opinion, as of September 30, 2021, that the Bank met all applicable capital adequacy requirements. As of September 30, 2021, the Bank is categorized as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the Bank must maintain minimum regulatory capital ratios as set forth in the table. There are no conditions or events since September 30, 2021 that management believes have changed the category. The Bank’s actual capital amounts and ratios are presented in the following tables: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ To Be Well ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Capitalized ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Under Prompt ​ ​ ​ ​ ​ ​ ​ For Capital Adequacy ​ Corrective ​ ​ Actual ​ Purposes ​ Action Provisions ​ Amount Ratio Amount ​ Ratio Amount ​ Ratio ​ September 30, 2021 ​ ​ ​ ​ ​ ​ ​ ​ Common Equity Tier 1 capital (to risk‑weighted assets) ​ $ 75,161 32.4 % $ ≥ 10,438 ≥ 4.5 % $ ≥ 15,077 ≥ 6.5 % Tier 1 capital (to risk‑weighted assets) ​ 75,161 32.4 ​ ≥ 13,917 ≥ 6.0 ​ ≥ 18,557 ≥ 8.0 ​ Total capital (to risk‑weighted assets) ​ 77,587 33.4 ​ ≥ 18,557 ≥ 8.0 ​ ≥ 23,196 ≥ 10.0 ​ Tier 1 capital (to average assets) ​ ​ 75,161 21.4 ​ ≥ 14,034 ≥ 4.0 ​ ≥ 17,543 ≥ 5.0 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ ​ ​ ​ ​ ​ ​ ​ Common Equity Tier 1 capital (to risk‑weighted assets) ​ $ 73,665 33.1 % $ ≥ 10,018 ≥ 4.5 % $ ≥ 14,471 ≥ 6.5 % Tier 1 capital (to risk‑weighted assets) ​ 73,665 33.1 ​ ≥ 13,358 ≥ 6.0 ​ ≥ 17,810 ≥ 8.0 ​ Total capital (to risk‑weighted assets) ​ 76,448 34.3 ​ ≥ 17,810 ≥ 8.0 ​ ≥ 22,263 ≥ 10.0 ​ Tier 1 capital (to average assets) ​ ​ 73,665 25.2 ​ ≥ 11,700 ≥ 4.0 ​ ≥ 14,625 ≥ 5.0 ​ ​

Fair Value

Fair Value
Fair Value	NOTE 11 – Fair Value Accounting standards describe three levels of inputs that may be used to measure fair value (the fair value hierarchy). The level of an asset or liability within the fair value hierarchy is based on the lowest level of input significant to the fair value measurement of that asset or liability. Following is a brief description of each level of the fair value hierarchy: Level 1 - Fair value measurement is based on quoted prices for identical assets or liabilities in active markets. Level 2 - Fair value measurement is based on: (1) quoted prices for similar assets or liabilities in active markets; (2) quoted prices for identical or similar assets or liabilities in markets that are not active; or (3) valuation models and methodologies for which all significant assumptions are or can be corroborated by observable market data. Level 3 - Fair value measurement is based on valuation models and methodologies that incorporate at least one significant assumption that cannot be corroborated by observable market data. Level 3 measurements reflect the Company’s estimates about assumptions market participants would use in measuring fair value of the asset or liability. Some assets and liabilities, such as securities available for sale, are measured at fair value on a recurring basis under accounting principles generally accepted in the United States. Other assets and liabilities, such as impaired loans, may be measured at fair value on a nonrecurring basis. Following is a description of the Company’s valuation methodology and significant inputs used for each asset and liability measured at fair value on a recurring or nonrecurring basis, as well as the classification of the asset or liability within the fair value hierarchy. Available for sale securities Loans Foreclosed assets Other equity investments Assets measured at fair value on a recurring basis are summarized below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Recurring Fair Value Measurements Using ​ ​ Quoted Prices ​ ​ ​ ​ ​ ​ ​ ​ ​ in Active ​ Significant ​ ​ ​ ​ ​ ​ ​ ​ Markets for ​ Other ​ Significant ​ ​ ​ ​ ​ Identical ​ Observable ​ Unobservable ​ ​ ​ ​ ​ Instruments ​ Inputs ​ Inputs ​ ​ ​ ​ ​ (Level 1) ​ (Level 2) ​ (Level 3) ​ Total ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of September 30, 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Available for sale securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Obligations of the US government and US government sponsored agencies ​ $ — ​ $ 1,093 ​ $ — ​ $ 1,093 Obligations of states and political subdivisions ​ ​ — ​ ​ 14,821 ​ ​ — ​ ​ 14,821 Mortgage-backed securities ​ ​ — ​ ​ 28,234 ​ ​ — ​ ​ 28,234 Certificates of deposit ​ ​ — ​ ​ 1,277 ​ ​ — ​ ​ 1,277 Corporate debt securities ​ ​ — ​ ​ 4,460 ​ ​ — ​ ​ 4,460 Total available for sale securities ​ $ — ​ $ 49,885 ​ $ — ​ $ 49,885 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of December 31, 2020 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Available for sale securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Obligations of the US government and US government sponsored agencies ​ $ — ​ $ 754 ​ $ — ​ $ 754 Obligations of states and political subdivisions ​ ​ — ​ ​ 15,605 ​ ​ — ​ ​ 15,605 Mortgage-backed securities ​ ​ — ​ ​ 37,680 ​ ​ — ​ ​ 37,680 Certificates of deposit ​ ​ — ​ ​ 7,937 ​ ​ — ​ ​ 7,937 Corporate debt securities ​ ​ — ​ ​ 2,267 ​ ​ — ​ ​ 2,267 Total available for sale securities ​ $ — ​ $ 64,243 ​ $ — ​ $ 64,243 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Information regarding the fair value of assets measured at fair value on a nonrecurring basis follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nonrecurring Fair Value Measurements Using ​ ​ ​ ​ Quoted Prices ​ ​ ​ ​ ​ ​ ​ ​ ​ in Active ​ Significant ​ ​ ​ ​ ​ ​ ​ ​ Markets for ​ Other ​ Significant ​ ​ Assets ​ Identical ​ Observable ​ Unobservable ​ ​ Measured at ​ Instruments ​ Inputs ​ Inputs ​ Fair Value ​ (Level 1) ​ (Level 2) ​ (Level 3) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of September 30, 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Other equity investments ​ $ 428 ​ $ — ​ $ 428 ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of December 31, 2020 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Loans ​ $ 254 ​ $ — ​ $ — ​ $ 254 Foreclosed assets ​ ​ 125 ​ ​ — ​ ​ — ​ ​ 125 Other equity investments ​ ​ 225 ​ ​ — ​ ​ 225 ​ ​ — ​ As of September 30, 2021 there were no impaired loans requiring a write down to their estimated fair value.

Summary of Significant Accounting Policies
Organization	Organization From October 2017 until January 2020, as discussed below, we operated in a two-tier mutual holding company structure. The predecessor FFBW, Inc. (“Old FFBW”) was a federal corporation that was the publicly traded stock holding company of First Federal Bank of Wisconsin (the “Bank”). At December 31, 2019, Old FFBW had 7,702,478 shares of common stock outstanding, of which 3,436,424 shares, or 44.6%, were owned by the public, including 29,325 shares owned by FFBW Community Foundation, and the remaining 4,266,054 shares were held by FFBW, MHC (the “MHC”), a federally chartered mutual holding company and former parent company of Old FFBW. ​ The Bank is a community bank headquartered in Waukesha, Wisconsin that provides financial services to individuals and businesses from our offices in Waukesha, Brookfield, and the South Side of Milwaukee. ​ FFBW, Inc. (the “Company”) is a Maryland corporation that was organized in September 2019 to be the successor to Old FFBW and be the savings and loan holding company for the Bank upon completion of the second step mutual-to-stock conversion (the “Conversion”) of the MHC. Prior to completion of the Conversion, approximately 55.4% of the shares of common stock of the Company were owned by the MHC. The Conversion was completed on January 16, 2020. In the Conversion, the Company sold 4,268,570 shares of common stock at $10.00 per share, for net proceeds of approximately $37.9 million (including the purchase of 341,485 ESOP shares), and issued 3,436,430 shares of common stock in exchange for the shares of Old FFBW common stock owned by Old FFBW stockholders, other than the MHC, as of the effective date of the conversion. As a result of the conversion, the MHC and Old FFBW ceased to exist. The Conversion was conducted pursuant to the MHC’s Plan of Conversion. The Plan of Conversion provided for the establishment, upon the completion of the Conversion, of special “liquidation accounts” for the benefit of certain depositors of the Bank in an amount equal to the MHC’s ownership interest in the stockholders’ equity of Old FFBW as of the date of the latest balance sheet contained in the prospectus plus the MHC’s net assets (excluding its ownership of Old FFBW). Following the completion of the Conversion, the Company and the Bank are not permitted to pay dividends on their capital stock if the Company’s shareholder’s equity, or the shareholder's equity of the Bank, would be reduced below the amount of the liquidation accounts. The liquidation accounts are reduced annually to the extent that eligible account holders have reduced their qualifying deposits. Subsequent increases in these accounts will not restore an eligible account holder's interest in the liquidation accounts. Direct costs of the Conversion and public offering, totaling approximately $1.2 million, were applied against the proceeds from the shares sold in the public offering.
Use of Estimates	Use of Estimates In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the fair values of securities, fair value of financial instruments, the valuation of other real estate owned and the valuation of deferred income tax assets.
Revenue Recognition	Revenue Recognition ​ Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers ("ASC 606"), establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity's contracts to provide goods or services to customers. The core principle requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those goods or services recognized as performance obligations are satisfied. ​ The majority of the Company's revenue-generating transactions are not subject to ASC 606, including all interest and dividend income generated from financial instruments. Certain noninterest income items, including loan servicing income, gain on sales of loans, gain on sales of securities, and other noninterest income have been evaluated and were determined to not fall within the scope of ASC 606. Elements of noninterest income that are within the scope of ASC 606, are as follows: ​ Service charges and other fees - The Company earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Management reviewed the deposit account agreements and determined that the agreements can be terminated at any time by either the Company or the account holder. Transaction fees, such as balance transfers, wires and overdraft charges are settled the day the performance obligation is satisfied. The Company's monthly service charges and maintenance fees are for services provided to the customer on a monthly basis and are considered a series of services that have the same pattern of transfer each month. The review of service charges assessed on deposit accounts included the amount of variable consideration that is a part of the monthly charges. It was found that the waiver of service charges due to insufficient funds and dormant account fees is immaterial and would not require a change in the accounting treatment for these fees under the new revenue standards. ​ Interchange fees - Customers use a Bank-issued debit card to purchase goods and services, and the Company earns interchange fees on those transactions, typically a percentage of the sale amount of the transaction. The Company records the amount due when it receives the settlement from the payment network. Payments from the payment network are received and recorded into income on a daily basis. These fees are included in “service charges and other fees” on the Consolidated Statements of Operations. There are no contingent debit card interchange fees recorded by the Company that could be subject to a clawback in future periods.
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of reporting cash flows, cash and cash equivalents include cash and balances due from banks, non-maturity deposits in the Federal Home Loan Bank of Chicago (FHLB), and fed funds sold. The Company has not experienced any losses in such accounts. ​
Available for Sale Securities	Available for Sale Securities Securities classified as available for sale are those securities that the Company intends to hold for an indefinite period of time, but not necessarily to maturity. Any decision to sell a security classified as available for sale would be based on various factors, including significant movements in interest rates, changes in the maturity mix of the Company’s assets and liabilities, liquidity needs, regulatory capital requirements, and other similar factors. Securities classified as available for sale are carried at fair value. Unrealized gains or losses are reported as increases or decreases in other comprehensive income, net of the related deferred tax effect. Realized gains or losses, determined on the basis of the cost of specific securities sold, are included in earnings. Gains and losses on the sale of securities are recorded on the trade date and determined using the specific-identification method. ​ Declines in fair value of securities that are deemed to be other than temporary, if applicable, are reflected in earnings as realized losses. In estimating other-than-temporary impairment losses, management considers the length of time and the extent to which fair value has been less than cost, the financial condition and near-term prospects of the issuer, and the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient enough to allow for any anticipated recovery in fair value. ​
Loans Acquired in a Transfer	Loans Acquired in a Transfer The Company acquires loans (including debt securities) individually and in groups or portfolios. These loans are initially measured at fair value with no allowance for loan losses. The Company’s allowance for loan losses on all acquired loans reflect only those losses incurred subsequent to acquisition. Certain acquired loans may have experienced deterioration of credit quality between origination and the Company’s acquisition of the loans. At acquisition, the Company reviews each loan to determine whether there is evidence of deterioration of credit quality since origination and if it is probable that the Company will be unable to collect all amounts due according to the loan’s contractual terms. If both conditions exist, the Company determines whether each such loan is to be accounted for individually or whether such loans will be assembled into pools of loans based on common risk characteristics (for example, credit score, loan type, and date of origination). The Company considers expected prepayments and estimates the amount and timing of undiscounted principal, interest, and other cash flows expected at acquisition for each loan and aggregated pool of loans. The excess of the loan’s or pool’s scheduled contractual principal and interest payments over all cash flows expected at acquisition is calculated as the nonaccretable difference. The excess of cash flows expected to be collected over the fair value of each loan or pool (accretable yield) is accreted into interest income over the remaining life of the loan or pool. At each reporting date, the Company continues to estimate cash flows expected to be collected for each loan or pool. If expected cash flows have decreased from the acquisition date estimate, the Company recognizes an allowance for loan losses. If expected cash flows have increased from the acquisition date estimate, the Company increases the amount of accretable yield to be recognized as interest income over the remaining life of the loan or pool.
Loans Held for Sale	Loans Held for Sale Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value in the aggregate. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. Mortgage loans held for sale are sold with the mortgage servicing rights released by the Company. Gains or losses on sales of mortgage loans are recognized based on the difference between the selling price and the carrying value of the related mortgage loan sold.
Loans	Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff generally are reported at their outstanding unpaid principal balances adjusted for deferred loan fees and costs, charge-offs, and an allowance for loan losses. Interest on loans is accrued and credited to income based on the unpaid principal balance. Loan-origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method. The accrual of interest on loans is discontinued when, in the opinion of management, there is an indication that the borrower may be unable to make payments as they become due. When loans are placed on nonaccrual status or charged off, all unpaid accrued interest is reversed against interest income. The interest on these loans is subsequently accounted for on the cash-basis or cost-recovery method until qualifying for return to accrual status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses is maintained at the level considered adequate by management to provide for losses that are probable as of the balance sheet date. The allowance for loan losses is established through a provision for loan losses charged to expense as losses are estimated to have occurred. Loan losses are charged against the allowance when management believes that the collectability of the principal is unlikely. Subsequent recoveries, if any, are credited to the allowance. In determining the adequacy of the allowance balance, the Company makes evaluations of the loan portfolio and related off-balance sheet commitments, considers current economic conditions and historical loss experience, and reviews specific problem loans and other factors. When establishing the allowance for loan losses, management categorizes loans into risk categories generally based on the nature of the collateral and the basis of repayment. These risk categories and their relevant risk characteristics are as follows: Commercial development: Commercial real estate: Commercial and industrial: One-to-four family owner-occupied: One-to-four family investor-owned: Multifamily real estate: Consumer: Management regularly evaluates the allowance for loan losses using the Company’s past loan loss experience, known and inherent risks in the loan portfolio, composition of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, current economic conditions, and other relevant factors. This evaluation is inherently subjective since it requires material estimates that may be susceptible to significant change. A loan is impaired when, based on current information, it is probable that the Company will not collect all amounts due in accordance with the contractual terms of the loan agreement. Management determines whether a loan is impaired on a case-by-case basis, taking into consideration the payment status, collateral value, length and reason of any payment delays, the borrower’s prior payment record, and any other relevant factors. Large groups of smaller-balance homogeneous loans, such as residential mortgage and consumer loans, are collectively evaluated in the allowance for loan losses analysis and are not subject to impairment analysis unless such loans have been subject to a restructuring agreement. Specific allowances for impaired loans are based on discounted cash flows of expected future payments using the loan’s initial effective interest rate or the fair value of the collateral if the loan is collateral dependent. In addition, various regulatory agencies periodically review the allowance for loan losses. These agencies may require the Company to make additions to the allowance for loan losses based on their judgments of collectability based on information available to them at the time of their examination.
Troubled Debt Restructurings	Troubled Debt Restructurings Loans are accounted for as troubled debt restructurings when a borrower is experiencing financial difficulties that lead to a restructuring of the loan and the Company grants a “concession” to the borrower that they would not otherwise consider. These concessions include a modification of terms, such as a reduction of the stated interest rate or loan balance, a reduction of accrued interest, an extension of the maturity date at an interest rate lower than a current market rate for a new loan with similar risk, or some combination thereof to facilitate repayment. Troubled debt restructurings are considered impaired loans.
Foreclosed Assets	Foreclosed Assets Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value, less costs to sell, at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less costs to sell. Revenue and expenses from operations and changes in the valuation allowance are included in net expenses from foreclosed assets.
Premises and Equipment	Premises and Equipment Depreciable assets are stated at cost less accumulated depreciation. Provisions for depreciation are computed on straight-line and accelerated methods over the estimated useful lives of the assets.
Other Equity Investments	Other Equity Investments ​ Other Equity Investments consist of Federal Home Loan Bank of Chicago (“FHLB”) stock and Bankers’ Bank stock. The value. The Company is required to hold the stock as a member of the FHLB and transfer of the stock is substantially restricted. The stock is evaluated for impairment on an annual basis. The Company is required to
Income Taxes	Income Taxes ​ Amounts provided for income tax expense are based on income reported for financial statement purposes and do not necessarily represent amounts currently payable under tax laws. Deferred income tax assets and liabilities are computed annually for differences between the financial statement and income tax basis of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. As changes in tax laws or rates are enacted, deferred income tax assets and liabilities are adjusted through the provision for income taxes. The differences relate principally to the allowances for loan losses, deferred compensation, depreciation, FHLB stock dividends and non-accrual interest. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. The tax effects from an uncertain tax position can be recognized in the financial statements only if the position is more likely than not to be sustained on audit, based on the technical merits of the position. The Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more likely than not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. Based on its evaluation, the Company has concluded that there are no significant uncertain tax positions requiring recognition in its financial statements. The Company’s policy is to recognize interest and penalties related to income tax issues as components of income tax expense. During the periods shown, the Company did not recognize any interest or penalties related to income tax expense in its statements of operations.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Advertising	Advertising Advertising costs are expensed as incurred.
Other Comprehensive Income (Loss)	Other Comprehensive Income (Loss) Other comprehensive income (loss) is shown on the statements of comprehensive income. The Company’s accumulated other comprehensive income (loss) is composed of the unrealized gains (losses) on securities available for sale, net of tax and is shown on the statements of changes in equity. Reclassification adjustments out of other comprehensive income (loss) for losses realized on sales of securities available for sale comprise the entire balance of “net gain on sale of securities” on the statements of operations.
Off-Balance Sheet Financial Instruments	Off-Balance Sheet Financial Instruments In the ordinary course of business, the Company has entered into off-balance-sheet financial instruments consisting of commitments to extend credit, unfunded commitments under lines of credit, and standby letters of credit. Such financial instruments are recorded in the financial statements when they become payable.
Life Insurance	Life Insurance The Company has purchased life insurance policies on certain key members of the management team. Life insurance is measured at the amount that could be realized under the insurance contract as of the balance sheet date, which is generally the cash surrender value of the policy.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The Company qualifies as an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). For as long as the Company is an emerging growth company, it may choose to take advantage of exemptions from various reporting requirements applicable to other public companies. An emerging growth company may elect to use the extended transition period to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies, but must make such election when the Company is first required to file a registration statement. The Company has elected to use the extended transition period described above and intends to maintain its emerging growth company status as allowed under the JOBS Act. The following ASUs have been issued by the FASB and may impact the Company's financial statements in future reporting periods: ​ ASU No. 2016-13, “Credit Losses (Topic 326).” ASU No. 2019-04, “Codification Improvements to Topic 326.” ASU No. 2019-05, “Financial Instruments-Credit Losses.” ​ ASU 2016-13 requires organizations to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Early adoption will be permitted for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is currently assessing the impact of adopting ASU 2016-13 on its financial statements. ​ ​ ASU No. 2016-02, “Leases (Topic 842): Amendments to the Leases Analysis.” ASU No. 2018-10, "Codification Improvements to Topic 842." ASU No. 2018-11, "Targeted Improvements" ​ For lessees, Topic 842 requires leases to be recognized on the balance sheet, along with disclosure of key information about leasing arrangements. Topic 842 was subsequently amended by ASU 2018-01, 2018-10 and 2018-11. The new standard establishes a right-of-use (ROU) model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification expense recognition in the income statement. ​ For lessors, Topic 842 requires lessors to classify leases as sales-type, direct financing or operating leases. A lease is a sales-type lease if any one of five criteria are met, each of which indicate that the lease, in effect, transfers control of the underlying asset to the lessee. If none of those five criteria are met, but two additional criteria are both met, indicating the lessor has transferred substantially all the risks and benefits of the underlying asset to the lessee and a third party, the lease is a direct financing lease. All leases that are not sales-type or direct financing leases are operating leases. ​ The new standard is effective for the Company on January 1, 2022, with early adoption permitted. A modified retrospective transition approach is required, applying the new standard to all leases existing at the date of initial application. An entity may choose to use either (1) the new standard's effective date or (2) the beginning of the earliest comparative period presented in the financial statements as its date of initial application. The Company expects to adopt the new standard on January 1, 2022 using the effective date as its date of initial application. The Company is expecting to record a right of use asset and corresponding lease obligation for its outstanding leases.
