Summary of Significant Accounting Policies | NOTE 2 - Summary of Significan Organization From October 2017 until January 2020, as discussed below, we operated in a two-tier mutual holding company structure. FFBW, Inc. (the “Company”) was a federal corporation that was the publicly traded stock holding company of First Federal Bank of Wisconsin (the “Bank”). At December 31, 2019, the Company 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 the Company. At December 31, 2019, the significant assets of the Company consisted of the capital stock of the Bank. The liabilities of the Company were insignificant. The Company was subject to the financial reporting requirements of the Securities Exchange Act of 1934, as amended. The Company was subject to regulation and examination by the Board of Governors of the Federal Reserve System (“the Federal Reserve Board”). 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. (“New FFBW”), a Maryland corporation that was organized in September 2019, is a savings and loan holding company headquartered in Waukesha, Wisconsin. New FFBW was formed to be the successor to the Company 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. In conjunction with the Conversion, the MHC and the Company merged into New FFBW. The Conversion was completed on January 16, 2020. In the Conversion, New FFBW sold 4,268,570 shares of common stock at $10.00 per share, for net proceeds of approximately $37.9 million (including purchase of 341,485 ESOP shares), and issued 3,436,430 shares of common stock in exchange for the shares of common stock of FFBW, Inc. a federal corporation, (“Old FFBW”) owned by stockholders of Old FFBW, other than FFBW, MHC, as of the effective date of the conversion. As a result of the conversion, FFBW, 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 the Company as of the date of the latest balance sheet contained in the prospectus plus the MHC’s net assets (excluding its ownership of the Company). Following the completion of the Conversion, the Company and the Bank are not permitted to pay dividends on their capital stock if the shareholders' equity of New FFBW, or the shareholder's equity of the Bank, would be reduced below the amount of the liquidation accounts. The liquidation accounts will be reduced annually to the extent that eligible account holders have reduced their qualifying deposits. Subsequent increases 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, have been 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 revenue 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 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: These loans are secured by vacant land and/or property that are in the process of improvement. Repayment of these loans can be dependent on the sale of the property to third parties or the successful completion of the improvements by the builder for the end user. Construction loans include not only construction of new structures, but loans originated to finance additions to or alterations of existing structures. Until a permanent loan originates, or payoff occurs, all commercial construction loans secured by real estate are reported in this loan pool. Development loans also have the risk that improvements will not be completed on time, or in accordance with specifications and projected costs. Commercial real estate: These loans are primarily secured by office and industrial buildings, warehouses, small retail shopping facilities, and various special purpose properties, including restaurants. These loans are subject to underwriting standards and processes similar to commercial and industrial loans. Loans to closely held businesses are generally guaranteed in full by the owners of the business. These loans are viewed primarily as cash flow loans and the repayment of these loans is largely dependent on the successful operation of the property. The cash flows of the borrowers, however, may not behave as forecasted and collateral securing loans may fluctuate in value due to the general economic factors or conditions specific to the real estate market, such as geographic location and/or purpose type. Commercial and industrial: Commercial and industrial loans are extended primarily to small and middle market customers. Such credits typically comprise working capital loans, asset acquisition loans, and loans for other business purposes. Loans to closely held businesses are generally guaranteed in full by the owners of the business. Commercial and industrial loans are made based primarily on the historical and projected cash flow of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of the borrowers, however, may not behave as forecasted and collateral securing loans may fluctuate in value due to economic or individual performance factors. Minimum standards and underwriting guidelines have been established for commercial and industrial loans. One-to-four family owner-occupied: These loans are generally to individuals and are underwritten by evaluating the credit history of the borrower, the ability of the borrower to meet the debt service requirements of the loan and total debt obligations, the underlying collateral, and the loan to collateral value. Also included in this category are junior liens on one-to-four family residential properties. Underwriting standards for one-to-four family owner-occupied loans are heavily influenced by statutory requirements, which include, but are not limited to, loan-to-value and affordability ratios, risk-based pricing strategies, and documentation requirements. One-to-four family investor-owned: These loans may be to individuals or businesses and are subject to underwriting standards and processes similar to commercial and industrial loans. These loans are viewed primarily as cash flow loans and the repayment of these loans is largely dependent on the successful operation of the property(ies). The cash flows of the borrowers, however, may not behave as forecasted and collateral securing loans may fluctuate in value due to the general economic factors or conditions specific to the real estate market, such as geographic location and/or purpose type. Multifamily real estate: These loans include loans to finance non-farm properties with five or more units in structures primarily to accommodate households. Such credits are typically originated to finance the acquisition or refinancing of an apartment building. These loans are subject to underwriting standards and processes similar to commercial and industrial loans. Loans to closely held businesses are generally guaranteed in full by the owners of the business. These loans are viewed primarily as cash flow loans and the repayment of these loans is largely dependent on the successful operation of the subject multifamily property, with assumptions made for vacancy rates. Cash flows of the borrowers rely on the receipt of rental income from the tenants of the property who are themselves subject to fluctuations in national and local economic conditions and unemployment trends. Consumer: These loans may take the form of installment loans, demand loans, or single payment loans, and are extended to individuals for household, family, and other personal expenditures. These loans generally include direct consumer automobile loans and credit card loans. These loans are generally smaller in size and are underwritten by evaluating the credit history of the borrower, the ability of the borrower to meet the debt service requirements of the loan and total debt obligations. 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 Company's investment in the FHLB stock is carried at cost, which approximates fair 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 adjust its reported value of Bankers’ Bank stock, which is considered an equity security without a readily determinable market value, if a comparable transaction is observed. 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 loss 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 memebers 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. Subsequent Events Subsequent events have been evaluated through May 11, 2021, which is the date the financial statements are available to be issued. 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 Company recently adopted the following Accounting Standards Updates (ASU) issued by the Financial Accounting Standards Board (FASB). ASU No. 2019-12, “Simplifying the Accounting for Income Taxes” This standard is intended to simplify the accounting for income taxes and improve the consistent application of accounting guidance through the following changes: 1) removes certain exceptions for recognizing deferred tax liabilities, tax allocations, and the calculation methodology for an interim year-to-date loss that exceeds the anticipated loss for the year; 2) requires a franchise tax or similar tax based partially on income be recognized as an income-based tax and account for any incremental amount incurred as a non-income based tax; 3) requires an entity evaluate when a step up in the tax basis of goodwill should be considered part of a business combination in which goodwill was originally recognized and when it should be considered a separate transaction; 4) does not require the allocation of consolidated current and deferred tax expense to a member entity that is not subject to tax in separate financial statements, but may elect to do so for certain legal entities that are disregarded by the taxing authority; and 5) amends guidance on the handling of an enacted change in tax law or rates within interim tax periods. This new standard is effective for financial statements issued for interim and annual periods beginning after December 15, 2020. The Company does not believe this will have a significant impact on its financial statements. ASU No. 2020-04 “Facilitation of the Effects of Reference Rate Reform on Financial Reporting” This standard provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued due to reference rate reform if certain criteria are met. Effective March 12, 2020, the amendments in this ASU are elective and prospectively applied only to contracts modified on or before December 31, 2022, or hedging relationships entered into or evaluated through December 31, 2022. The adoption of this standard has not impacted the Company’s financial staetments and management does not believe it will have a significant impact moving forward. 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 evaluating what impact this standard will have on its consolidated financial statements. ASU No. 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement” This ASU modifies the disclosure requirements on fair value measurements in Topic 820, including the removal, modification to, and addition of certain disclosure requirements. This ASU was adopted effective January 1, 2020. Given the nature of the Company’s fair value instruments, the i |
