Accounting Policies [Abstract]
Organization	Organization 1895 Bancorp of Wisconsin, Inc. (the “Company”) was formed in January 2019 to serve as the mid-tier stock holding company for PyraMax Bank, FSB (the “Bank”) upon the reorganization of the Bank into the two-tier mutual holding company structure. The reorganization was completed on January 8, 2019. Prior to January 8, 2019, the Company had no assets or liabilities and had not conducted any business activities other than organizational activities. Accordingly, the audited consolidated financial statements and other financial information contained in these consolidated financial statements relate solely to the Bank for periods prior to January 8, 2019. On January 8, 2019, PyraMax Bank, FSB (the “Bank”) converted to a stock savings bank and is now organized in the mutual holding company structure. The Bank issued all of its outstanding stock to the Company, which sold 2,145,738 shares of common stock to the public at $10.00 per share, including 175,528 shares purchased by the Bank’s employee stock ownership plan (“ESOP”). In connection with the reorganization, the Company also issued 48,767 shares of common stock to 1895 Bancorp of Wisconsin Community Foundation, Inc. and 2,682,172 shares of common stock to 1895 Bancorp of Wisconsin, MHC, the federally-chartered mutual holding company. The cost of the reorganization and the issuing of the common stock totaling $1,816 were deferred and deducted from the sales proceeds of the offering. The Bank operates as a full-service financial institution, providing a full range of financial services, including the granting of commercial, residential, and consumer loans and acceptance of deposits from individual customers and small businesses in the metropolitan Milwaukee, Wisconsin, area. The Bank is subject to competition from other financial and nonfinancial institutions providing financial products. In addition, the Bank is subject to the regulations of certain regulatory agencies and undergoes periodic examination by those regulatory agencies. Jumpstart Our Business Startups Act The Jumpstart Our Business Startups Act (the JOBS Act), which was signed into law on April 5, 2012, has made numerous changes to the federal securities laws to facilitate access to capital markets. Under the JOBS Act, a company with total annual gross revenues of less than $1.0 billion during its most recently completed fiscal year qualifies as an “emerging growth company.” The Company qualifies as an “emerging growth company” and believes that it will continue to qualify as an “emerging growth company” until five years from the completion of the stock offering. As an “emerging growth company,” the Company has elected 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. Accordingly, the financial statements may not be comparable to the financial statements of companies that comply with such new or revised accounting standards.
Use of Estimates	Use of Estimates In preparing consolidated 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, the fair values of financial instruments, mortgage servicing rights, and the valuation of deferred income tax assets.
Revenue Recognition	Revenue Recognition Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (Topic 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 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. NOTE 1 — Summary of Significant Accounting Policies – (continued) The Company completed its overall assessment of revenue streams and related contracts affected by the Topic 606 guidance. The majority of the Company’s revenue-generating transactions are not subject to Topic 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 to not fall within the scope of Topic 606. Elements of noninterest income that is within the scope Topic 606 are as follows: Fee income on deposit accounts – Revenue from fees charged on deposit accounts is earned through deposit-related services; as well as account maintenance and management, overdraft, non-sufficient funds and other deposit-related fees. Revenue is recognized either over time, corresponding with the deposit accounts’ monthly cycle, or at a point in time when transactional based fees and services occur. 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. Recognition of revenue under Topic 606 did not materially change the timing or magnitude of revenue recognition Sale of foreclosed assets – Revenue from the sale of foreclosed assets is recognized at a point in time when control of the promised asset transfers to the buyer. The Company uses the following indicators to determine when control of a promised asset has been transferred: the seller has a present right to payment for the asset; the buyer has legal title of the asset; the seller has transferred physical possession of the asset; the buyer has the significant risks and rewards of ownership of the asset; or the buyer has accepted the asset. Recognition of revenue under Topic 606 did not materially change the timing or magnitude of revenue recognition Merchant card arrangement fees – Customers use a Bank-issued debit or credit card to purchase goods and services, and the Company earns interchange fees on these 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. There are no contingent debit or credit card interchange fees recorded by the Company that could be subject to a clawback in future periods. Recognition of revenue under Topic 606 did not materially change the timing or magnitude of revenue recognition
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of reporting cash flows, cash and cash equivalents include cash on hand, interest-bearing and non-interest-bearing accounts in other financial institutions, and federal funds sold, all of which have original maturities of three months or less.
Securities	Securities Debt 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. Interest and dividends on available securities are recognized as income when earned. Amortization of premiums and accretion of discounts are recognized in interest income using the interest method over the estimated lives of the securities. Mutual fund investments are held as trading securities until January 1, 2019 upon adoption of ASU 2016-01, and carried at fair value, with changes in fair value reported in net income. These mutual fund investments were reclassified as marketable equity securities as of January 1, 2019 upon adoption of ASU 2016-01 and included in other assets on the balance sheet. 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 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. 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 non-accrual 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 real estate: These loans are dependent on the industries tied to these loans. Commercial real estate loans are secured primarily by office and industrial buildings, warehouses, small retail shopping facilities, and various special-purpose properties, including hotels and restaurants. Financial information is obtained from borrowers and/or the individual project to evaluate cash flow sufficiency to service debt and is periodically updated during the life of the loan. Loan performance may be adversely affected by factors impacting the general economy or conditions specific to the real estate market, such as geographic location and/or property type, Land development: These loans are secured by vacant land and/or property that are in the process of improvement, including (a) land development preparatory to erecting vertical improvements or (b) the on-site construction of industrial, commercial, residential, or farm buildings. 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. In the event a loan is made on property that is not yet improved for the planned development, there is the risk that necessary approvals will not be granted or will be delayed. Construction loans also run the risk that improvements will not be completed on time or in accordance with specifications and projected costs. Commercial Other: This loan category is comprised of commercial and industrial loans. 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. Residential real estate: 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. Underwriting standards for residential real estate 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. 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. Also included in this category are junior liens on 1-4 family residential properties. 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. NOTE 1 — Summary of Significant Accounting Policies – (continued) 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.
Premises and Equipment	Premises and Equipment Depreciable assets are stated at cost less accumulated depreciation. Provisions for depreciation are computed on straight-line method over the estimated useful lives of the assets.
Mortgage Servicing Rights	Mortgage Servicing Rights Mortgage servicing rights are recognized as separate assets when rights are acquired through sale of mortgage loans. Mortgage servicing rights acquired through sale of loans are recognized as a component of loan servicing income and are recorded at fair value. The fair value of mortgage servicing rights is estimated using a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as costs to service, a discount rate, the custodial earnings rate, ancillary income, default rates and losses, and prepayment speeds. The fair value of mortgage servicing rights may change because of changes in the discount rates, prepayment expectations, default rates, and other factors. Mortgage servicing rights are amortized into income in proportion to and over the period of the estimated future net servicing income of the underlying loans. Mortgage servicing rights are evaluated for impairment at least annually and whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The evaluation includes stratifying the mortgage servicing rights by predominant characteristics such as interest rates and terms and estimating fair value of each stratum. Impairment is recognized through a valuation allowance for an individual stratum to the extent that fair value is less than the carrying amount for the stratum.
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock The Company’s investment in Federal Home Loan Bank (“FHLB”) stock is carried at cost. 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 pledged as collateral for outstanding FHLB advances. The stock is evaluated for impairment on an annual basis.
Foreclosed Assets	Foreclosed Assets Assets acquired through or in lieu of loan foreclosure are held for sale and are initially recorded at fair value 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 foreclosed asset expense. There were no foreclosed assets as of December 31, 2019 and 2018, respectively. There were approximately $240 and $161 of residential real estate loans in process of foreclosure at December 31, 2019 and 2018, respectively.
Cash value of life insurance	Cash value of life insurance The Company purchased bank owned life insurance on the lives of certain employees. The Company is the beneficiary of the life insurance policies. The cash surrender value of life insurance is reported at the amount that would be received in cash if the policies were surrendered. Increases in the cash value of the policies and proceeds of death benefits received are recorded in noninterest income. The increase in cash value of life insurance is not subject to income taxes, as long as the Company has the intent and ability to hold the policies until the death benefits are received.
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 consolidated 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 consolidated 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 consolidated 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.
Employee Benefit Plans	Employee Benefit Plans The Company has employee benefit plans for qualified employees. The Company’s policy is to fund contributions as accrued.
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 including commitments to extend credit, unfunded commitments under lines of credit, and standby letters of credit. Such financial instruments are recorded in the consolidated financial statements when they become payable.
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.
Rate Lock Commitments	Rate Lock Commitments The Company enters into commitments to originate loans, whereby the interest rate on the loan is determined prior to funding (rate lock commitments). Rate lock commitments on mortgage loans that are intended to be sold are considered to be derivatives. Accordingly, such commitments, along with any related fees received from potential borrowers, are recorded at fair value in other assets or liabilities, with changes in fair value recorded in the net gain or loss on sale of mortgage loans. Fair value is based on fees currently charged to enter into similar agreements and for fixed-rate commitments also considers the difference between current levels of interest rates and the committed rates.
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 (loss). The Company’s accumulated other comprehensive loss is composed of the unrealized loss on securities available for sale, net of tax and is shown on the statements of changes in equity. Reclassification adjustments out of other comprehensive loss for gains realized on sales of securities available for sale comprise the entire balance of “net gain on sale of securities” on the statements of operations. As part of this reclassification, income tax expense of approximately $0 and $18 was recognized for the years ended December 31, 2019 and 2018, respectively, in “provision (credit) for income taxes” on the statements of operations.
Reclassifications	Reclassifications Certain reclassifications have been made to the 2018 consolidated financial statements to conform to the 2019 classifications.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The Company recently adopted the following Accounting Standards Updates (ASU) issued by the Financial Accounting Standards Board (FASB): ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Liabilities. This ASU applies to all entities that hold financial assets or owe financial liabilities, and is intended to provide more useful information on the recognition, measurement, presentation and disclosure of financial instruments. Among other things, this ASU 1) requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; 2) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; 3) eliminates the requirement to disclose the fair values of financial instruments measured at amortized cost for entities that are not public business entities; 4) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the consolidated financial statements; and 5) clarifies that an entity should evaluate the need for a valuation allowance on deferred tax assets related to available-for-sale securities in combination with the entity’s other deferred tax assets. ASU 2014-09, Revenue from Contracts with Customers (Topic 606). This amendment supersedes and replaces nearly all existing revenue recognition guidance. Under the amended guidance, an entity should recognize revenue to depict the transfer of promised 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 Company adopted this accounting standard January 1, 2019, with no material impact on the Company’s consolidated financial statements. ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU amends previous guidance over eight specific cash flow classification issues with the objective of reducing the existing diversity in practice. Management adopted this new accounting standard on January 1, 2019, with no material impact on the Company’s consolidated financial statements. The following ASUs have been issued by the FASB and may impact the Company’s consolidated financial statements in future reporting periods. ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments (Topic 326). 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, 2021. Early adoption will be permitted for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. On November 15, 2019, the FASB issued ASU 2019-10, Financial Instruments – Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates, amending the effective date for this standard. ASU 2016-13 will be effective for reporting periods beginning after December 15, 2022. Management has elected to defer adoption to the new effective date and is currently evaluating the impact of adopting ASU 2016-13 on the Company’s consolidated financial statements. ASU 2016-02, Leases (Topic 842). This ASU affects any entity that enters into a lease, and is intended to increase the transparency and comparability of financial reporting. The ASU requires, among other changes, a lessee to recognize on its balance sheet a lease asset and a lease liability for those leases previously classified as operating leases. The lease asset will represent the right to use the underlying asset for the lease term, and the lease liability will represent the discounted value of the required lease payments to the lessor. The ASU will also require entities to disclose key information about leasing arrangements. ASU 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2019. Early adoption is permitted. On November 15, 2019, the FASB issued ASU 2019-10, Financial Instruments – Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates, amending the effective date for this standard. ASU 2016-02 will be effective for reporting periods beginning after December 15, 2021. Management has elected to defer adoption to the new effective date and is currently evaluating the impact of adopting ASU 2016-02 on the Company’s consolidated financial statements.

(the “Company”) was formed in January 2019 to serve as the mid-tier stock holding company for PyraMax Bank, FSB (the “Bank”) upon the reorganization of the Bank into the two-tier mutual holding company structure. The reorganization was completed on January 8, 2019. Prior to January 8, 2019, the Company had no assets or liabilities and had not conducted any business activities other than organizational activities.

The cost of the reorganization and the issuing of the common stock totaling $1,816 were deferred and deducted from the sales proceeds of the offering.

The Bank operates as a full-service financial institution, providing a full range of financial services, including the granting of commercial, residential, and consumer loans and acceptance of deposits from individual customers and small businesses in the metropolitan Milwaukee, Wisconsin, area. The Bank is subject to competition from other financial and nonfinancial institutions providing financial products. In addition, the Bank is subject to the regulations of certain regulatory agencies and undergoes periodic examination by those regulatory agencies.

Jumpstart Our Business Startups Act

The Jumpstart Our Business Startups Act (the JOBS Act), which was signed into law on April 5, 2012, has made numerous changes to the federal securities laws to facilitate access to capital markets. Under the JOBS Act, a company with total annual gross revenues of less than $1.0 billion during its most recently completed fiscal year qualifies as an “emerging growth company.” The Company qualifies as an “emerging growth company” and believes that it will continue to qualify as an “emerging growth company” until five years from the completion of the stock offering.

As an “emerging growth company,” the Company has elected 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. Accordingly, the financial statements may not be comparable to the financial statements of companies that comply with such new or revised accounting standards.

Use of Estimates

In preparing consolidated 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, the fair values of financial instruments, mortgage servicing rights, and the valuation of deferred income tax assets.

Revenue Recognition

Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (Topic 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 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.

NOTE 1 — Summary of Significant Accounting Policies – (continued)

The Company completed its overall assessment of revenue streams and related contracts affected by the Topic 606 guidance. The majority of the Company’s revenue-generating transactions are not subject to Topic 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 to not fall within the scope of Topic 606. Elements of noninterest income that is within the scope Topic 606 are as follows:

Fee income on deposit accounts – Revenue from fees charged on deposit accounts is earned through deposit-related services; as well as account maintenance and management, overdraft, non-sufficient funds and other deposit-related fees. Revenue is recognized either over time, corresponding with the deposit accounts’ monthly cycle, or at a point in time when transactional based fees and services occur. 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. Recognition of revenue under Topic 606 did not materially change the timing or magnitude of revenue recognition

Sale of foreclosed assets – Revenue from the sale of foreclosed assets is recognized at a point in time when control of the promised asset transfers to the buyer. The Company uses the following indicators to determine when control of a promised asset has been transferred: the seller has a present right to payment for the asset; the buyer has legal title of the asset; the seller has transferred physical possession of the asset; the buyer has the significant risks and rewards of ownership of the asset; or the buyer has accepted the asset. Recognition of revenue under Topic 606 did not materially change the timing or magnitude of revenue recognition

Merchant card arrangement fees – Customers use a Bank-issued debit or credit card to purchase goods and services, and the Company earns interchange fees on these 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. There are no contingent debit or credit card interchange fees recorded by the Company that could be subject to a clawback in future periods. Recognition of revenue under Topic 606 did not materially change the timing or magnitude of revenue recognition

Cash and Cash Equivalents

For purposes of reporting cash flows, cash and cash equivalents include cash on hand, interest-bearing and non-interest-bearing accounts in other financial institutions, and federal funds sold, all of which have original maturities of three months or less.

Securities

Debt 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. Interest and dividends on available securities are recognized as income when earned. Amortization of premiums and accretion of discounts are recognized in interest income using the interest method over the estimated lives of the securities.

Mutual fund investments are held as trading securities until January 1, 2019 upon adoption of ASU 2016-01, and carried at fair value, with changes in fair value reported in net income. These mutual fund investments were reclassified as marketable equity securities as of January 1, 2019 upon adoption of ASU 2016-01 and included in other assets on the balance sheet.

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 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. 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 non-accrual 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 real estate: These loans are dependent on the industries tied to these loans. Commercial real estate loans are secured primarily by office and industrial buildings, warehouses, small retail shopping facilities, and various special-purpose properties, including hotels and restaurants. Financial information is obtained from borrowers and/or the individual project to evaluate cash flow sufficiency to service debt and is periodically updated during the life of the loan. Loan performance may be adversely affected by factors impacting the general economy or conditions specific to the real estate market, such as geographic location and/or property type,

Land development: These loans are secured by vacant land and/or property that are in the process of improvement, including (a) land development preparatory to erecting vertical improvements or (b) the on-site construction of industrial, commercial, residential, or farm buildings. 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. In the event a loan is made on property that is not yet improved for the planned development, there is the risk that necessary approvals will not be granted or will be delayed. Construction loans also run the risk that improvements will not be completed on time or in accordance with specifications and projected costs.

Commercial Other: This loan category is comprised of commercial and industrial loans. 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.

Residential real estate: 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. Underwriting standards for residential real estate 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.

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. Also included in this category are junior liens on 1-4 family residential properties. 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.

NOTE 1 — Summary of Significant Accounting Policies – (continued)

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.

Premises and Equipment

Depreciable assets are stated at cost less accumulated depreciation. Provisions for depreciation are computed on straight-line method over the estimated useful lives of the assets.

Mortgage Servicing Rights

Mortgage servicing rights are recognized as separate assets when rights are acquired through sale of mortgage loans. Mortgage servicing rights acquired through sale of loans are recognized as a component of loan servicing income and are recorded at fair value. The fair value of mortgage servicing rights is estimated using a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as costs to service, a discount rate, the custodial earnings rate, ancillary income, default rates and losses, and prepayment speeds. The fair value of mortgage servicing rights may change because of changes in the discount rates, prepayment expectations, default rates, and other factors. Mortgage servicing rights are amortized into income in proportion to and over the period of the estimated future net servicing income of the underlying loans.

Mortgage servicing rights are evaluated for impairment at least annually and whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The evaluation includes stratifying the mortgage servicing rights by predominant characteristics such as interest rates and terms and estimating fair value of each stratum. Impairment is recognized through a valuation allowance for an individual stratum to the extent that fair value is less than the carrying amount for the stratum.

Federal Home Loan Bank Stock

The Company’s investment in Federal Home Loan Bank (“FHLB”) stock is carried at cost. 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 pledged as collateral for outstanding FHLB advances. The stock is evaluated for impairment on an annual basis.

Foreclosed Assets

Assets acquired through or in lieu of loan foreclosure are held for sale and are initially recorded at fair value 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 foreclosed asset expense. There were no foreclosed assets as of December 31, 2019 and 2018, respectively. There were approximately $240 and $161 of residential real estate loans in process of foreclosure at December 31, 2019 and 2018, respectively.

Cash value of life insurance

The Company purchased bank owned life insurance on the lives of certain employees. The Company is the beneficiary of the life insurance policies. The cash surrender value of life insurance is reported at the amount that would be received in cash if the policies were surrendered. Increases in the cash value of the policies and proceeds of death benefits received are recorded in noninterest income. The increase in cash value of life insurance is not subject to income taxes, as long as the Company has the intent and ability to hold the policies until the death benefits are received.

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 consolidated 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 consolidated 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 consolidated 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.

Employee Benefit Plans

The Company has employee benefit plans for qualified employees. The Company’s policy is to fund contributions as accrued.

Off-Balance Sheet Financial Instruments

In the ordinary course of business, the Company has entered into off-balance-sheet financial instruments including commitments to extend credit, unfunded commitments under lines of credit, and standby letters of credit. Such financial instruments are recorded in the consolidated financial statements when they become payable.

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.

Rate Lock Commitments

The Company enters into commitments to originate loans, whereby the interest rate on the loan is determined prior to funding (rate lock commitments). Rate lock commitments on mortgage loans that are intended to be sold are considered to be derivatives. Accordingly, such commitments, along with any related fees received from potential borrowers, are recorded at fair value in other assets or liabilities, with changes in fair value recorded in the net gain or loss on sale of mortgage loans. Fair value is based on fees currently charged to enter into similar agreements and for fixed-rate commitments also considers the difference between current levels of interest rates and the committed rates.

Advertising

Advertising costs are expensed as incurred.

Other Comprehensive Income (Loss)

Other comprehensive income (loss) is shown on the statements of comprehensive income (loss). The Company’s accumulated other comprehensive loss is composed of the unrealized loss on securities available for sale, net of tax and is shown on the statements of changes in equity. Reclassification adjustments out of other comprehensive loss for gains realized on sales of securities available for sale comprise the entire balance of “net gain on sale of securities” on the statements of operations. As part of this reclassification, income tax expense of approximately $0 and $18 was recognized for the years ended December 31, 2019 and 2018, respectively, in “provision (credit) for income taxes” on the statements of operations.

Reclassifications

Certain reclassifications have been made to the 2018 consolidated financial statements to conform to the 2019 classifications.

Recent Accounting Pronouncements

The Company recently adopted the following Accounting Standards Updates (ASU) issued by the Financial Accounting Standards Board (FASB):

ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Liabilities. This ASU applies to all entities that hold financial assets or owe financial liabilities, and is intended to provide more useful information on the recognition, measurement, presentation and disclosure of financial instruments. Among other things, this ASU 1) requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; 2) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; 3) eliminates the requirement to disclose the fair values of financial instruments measured at amortized cost for entities that are not public business entities; 4) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the consolidated financial statements; and 5) clarifies that an entity should evaluate the need for a valuation allowance on deferred tax assets related to available-for-sale securities in combination with the entity’s other deferred tax assets.

ASU 2014-09, Revenue from Contracts with Customers (Topic 606). This amendment supersedes and replaces nearly all existing revenue recognition guidance. Under the amended guidance, an entity should recognize revenue to depict the transfer of promised 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 Company adopted this accounting standard January 1, 2019, with no material impact on the Company’s consolidated financial statements.

ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU amends previous guidance over eight specific cash flow classification issues with the objective of reducing the existing diversity in practice. Management adopted this new accounting standard on January 1, 2019, with no material impact on the Company’s consolidated financial statements.

The following ASUs have been issued by the FASB and may impact the Company’s consolidated financial statements in future reporting periods.

ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments (Topic 326). 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, 2021. Early adoption will be permitted for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. On November 15, 2019, the FASB issued ASU 2019-10, Financial Instruments – Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates, amending the effective date for this standard. ASU 2016-13 will be effective for reporting periods beginning after December 15, 2022. Management has elected to defer adoption to the new effective date and is currently evaluating the impact of adopting ASU 2016-13 on the Company’s consolidated financial statements.

ASU 2016-02, Leases (Topic 842). This ASU affects any entity that enters into a lease, and is intended to increase the transparency and comparability of financial reporting. The ASU requires, among other changes, a lessee to recognize on its balance sheet a lease asset and a lease liability for those leases previously classified as operating leases. The lease asset will represent the right to use the underlying asset for the lease term, and the lease liability will represent the discounted value of the required lease payments to the lessor. The ASU will also require entities to disclose key information about leasing arrangements. ASU 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2019. Early adoption is permitted. On November 15, 2019, the FASB issued ASU 2019-10, Financial Instruments – Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates, amending the effective date for this standard. ASU 2016-02 will be effective for reporting periods beginning after December 15, 2021. Management has elected to defer adoption to the new effective date and is currently evaluating the impact of adopting ASU 2016-02 on the Company’s consolidated financial statements.
