These unrealized losses relate principally to changes in interest rates and were not caused by changes in the financial condition of the issuers, the quality of any underlying assets or applicable credit enhancements. In analyzing whether unrealized losses on debt securities are other-than-temporary, management considers whether the securities are issued by a government body or agency, whether a rating agency has downgraded the securities, industry analysts’ reports, the financial condition and performance of the issuer and the quality of any underlying assets or credit enhancements. As management has the intent and ability to hold these debt securities to projected recovery, none of these declines are deemed to be other-than-temporary.

Significant loan concentrations are considered to exist for a financial institution when there are amounts loaned to one borrower or to multiple borrowers engaged in similar activities that would cause them to be similarly impacted by economic or other conditions. While the Company’s credit risks are geographically concentrated within the metropolitan Milwaukee, Wisconsin area, there are no concentrations with individual borrowers or groups of related borrowers. During the normal course of business, the Company may transfer a portion of a loan as a participation loan to another financial institution in order to manage portfolio risk. In order to be eligible for sales treatment, all cash flows from the loan must be divided proportionately, and rights of each loan holder must have the same priority, the loan holders must have no recourse to the transferor other than standard representations and warranties, and no loan holder can have the right to pledge or exchange the entire loan. As of September 30, 2021 and December 31, 2020, respectively, the Company had transferred $32.3 million and $29.6 million in participation loans which were eligible for sales treatment to other financial institutions, all of which continue to be serviced by the Company.

The model incorporates various assumptions such as discount rates, prepayment speeds and ancillary income and servicing costs. As of September 30, 2021, the model used discount rates ranging from 10% to 13.5%, and prepayment speeds ranging from 12.5% to 39.7%, respectively, both of which were based on market data from independent organizations. As of September 30, 2020, the model used discount rates ranging from 10% to 13.5%, and prepayment speeds ranging from 20.9% to 46.9%, respectively, both of which were based on market data from independent organizations. The following table summarizes the estimated future amortization expense for mortgage servicing rights for the annual periods indicated.

The Company maintains a master contract agreement with the Federal Home Loan Bank, which provides for borrowing up to the lesser of 22.22 times the value of the Federal Home Loan Bank stock owned, a determined percentage of the book value of the Company’s qualifying real estate loans, or a determined percentage of the Company’s assets. The Federal Home Loan Bank provides both fixed and floating rate advances. Floating rates are tied to short-term market rates of interest such as the London InterBank Offered Rate, federal funds or Treasury bill rates. Federal Home Loan Bank advances are subject to a prepayment penalty if they are repaid prior to maturity. The Company has pledged approximately $150.1 million and $149.1 million of qualifying loans as collateral for Federal Home Loan Bank advances as of September 30, 2021 and December 31, 2020, respectively. Federal Home Loan Bank advances are also secured by approximately $3.0 million of Federal Home Loan Bank stock held by the Company as of September 30, 2021 and December 31, 2020. The Company’s available and unused portion of this borrowing agreement totaled $93.6 million and $79.6 million as of September 30, 2021 and December 31, 2020, respectively. Additional borrowing would require additional stock purchase. Additionally, at September 30, 2021 we had a $15.0 million federal funds rate line of credit with the BMO Harris Bank, none of which was drawn at September 30, 2021. The Company also had a $6.2 million line of credit at the Federal Reserve based on pledged commercial real estate loans of approximately $9.2 million at September 30, 2021. The Company had not drawn on the Federal Reserve line as of September 30, 2021.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 8 – INCOME TAXES Income tax (benefit) expense was ($57,000) and $1.2 million for the three months ended September 30, 2021 and 2020, respectively, and $45,000 and $1.6 million for the nine months ended September 30, 2021 and 2020, respectively. Deferred tax assets are deferred tax consequences attributable to deductible temporary differences and carryforwards. After the deferred tax asset has been measured using the applicable enacted tax rate and provisions of the enacted tax law, it is then necessary to assess the need for a valuation allowance. A valuation allowance is needed when, based on the weight of the available evidence, it is more likely than not that some portion of the deferred asset will not be realized. As required by generally accepted accounting principles, available evidence is weighted heavily on cumulative losses, with less weight placed on future projected profitability. The realization of deferred tax assets is dependent on the existence of taxable income of the appropriate character (e.g., ordinary or capital) within the carry-back and carry-forward periods available under tax law, which would consider future reversals of existing taxable temporary differences and available tax planning strategies. As of September 30, 2021, and December 31, 2020, the deferred tax valuation allowances was $934,000, reducing our net deferred tax asset to $3.4 million at each respective date. Due to recent changes in market conditions and current events related to COVID-19,

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 9 – COMMITMENTS AND CONTINGENCIES In the normal course of business, the Company may be involved in various legal proceedings. In the opinion of management, any liability resulting from such proceedings would not have a material adverse effect on the Company’s financial statements. No material legal proceedings existed at September 30, 2021. In the normal course of business, the Company is party to financial instruments with off-balance-sheet The Company’s exposure to credit losses is represented by the contractual, or notional, amount of these commitments. The Company follows the same credit policies in making commitments as it does for on-balance-sheet The contractual amounts of off-balance-sheet September 30, 2021 Fixed Rate Variable Rate Total (in thousands) Commitments to extend credit $ 8,215 $ 54,658 $ 62,873 Standby letters of credit 23 250 273 Credit enhancement under the FHLB of Chicago Mortgage Partnership Finance Program 1,200 — 1,200 Commitments to sell loans 14,404 — 14,404 Overdraft protection program commitments 4,027 — 4,027 December 31, 2020 Fixed Rate Variable Rate Total (in thousands) Commitments to extend credit $ 12,084 $ 41,778 $ 53,862 Standby letters of credit 23 2,150 2,173 Credit enhancement under the FHLB of Chicago Mortgage Partnership Finance Program 1,087 — 1,087 Commitments to sell loans 53,847 — 53,847 Overdraft protection program commitments 4,104 — 4,104 Commitments to extend credit are agreements to lend to a customer at fixed or variable rates, as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The amount of collateral obtained upon extension of credit is based on management’s credit evaluation of the customer. Collateral held varies but may include accounts receivable; inventory; property, plant and equipment; real estate; and stocks and bonds. Commitments to sell loans represent commitments obtained by the Company from a secondary market agency to purchase mortgages from the Company at specified interest rates and within specified periods of time. Standby letters of credit are conditional lending commitments issued by the Company to guarantee the performance of a customer to a third party. Generally, all standby letters of credit have expiration dates within one year. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loan facilities to customers. The Company generally holds collateral supporting these commitments. Standby letters of credit are not reflected in the financial statements, since recording the fair value of these guarantees would not have a significant impact on the financial statements. The Company participates in the Federal Home Loan Bank of Chicago Mortgage Partnership Finance Program (the “Program”). In addition to entering into forward commitments to sell mortgage loans to a secondary market agency, the Company enters into firm commitments to deliver loans to the Federal Home Loan Bank of Chicago through the Program. Under the Program, loans are funded by the Federal Home Loan Bank of Chicago, and the Company receives an agency fee reported as a component of gain on sale of loans. The Company had $2.5 million of commitments to deliver loans through the Program as of September 30, 2021. Once delivered to the Program, the Company provides a contractually agreed-upon credit enhancement and performs servicing of the loans. Under the credit enhancement, the Company is liable for losses on loans delivered through the Program after application of any mortgage insurance and a contractually agreed-upon credit enhancement provided by the Program, subject to an agreed-upon maximum. The Company receives a fee for this credit enhancement. The Company records a liability for expected losses in excess of anticipated credit enhancement fees. As of September 30, 2021, and December 31, 2020, the Company had no liability outstanding related to the Program. Unfunded commitments under overdraft protection agreements are commitments for possible future extensions of credit to existing customers. These lines of credit may or may not require collateral and may or may not contain a specific maturity date.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Employee Stock Ownership Plan	NOTE 10 – EMPLOYEE STOCK OWNERSHIP PLAN The Company established a tax qualified Employee Stock Ownership Plan (“ESOP”) for the benefit of its employees, effective January 1, 2019, in connection with the mutual holding company reorganization and organization of Old 1895 Bancorp. Eligible employees become 20% vested in their accounts after 1 year of service, 40% vested after 2 years of service, 60% vested after 3 years of service, 80% vested after 4 years of service, and 100% vested after 5 or more years of service, or earlier, upon death, disability or attainment of normal retirement age. On January 8, 2019, the ESOP purchased 175,528 shares of the Company’s common stock, which was funded by a loan from Old 1895 Bancorp. Unreleased ESOP shares collateralize the loan payable, and the cost of the shares is recorded as contra-equity account in the stockholders’ equity of the Company. Shares are to be released as debt payments are made by the ESOP to the loan. The ESOP’s sources of repayment of the loan can include dividends, if any, on the unallocated stock held by the ESOP, and discretionary contributions from the Company to the ESOP and earnings thereon. As part of the mutual-to-stock Compensation expense for the ESOP is recorded at an amount equal to the shares allocated by the ESOP multiplied by the average fair market value of the shares during the period. The Company recognizes compensation expense ratably over the year based upon the Company’s estimate of the number of shares expected to be allocated by the ESOP. Unearned compensation applicable to the ESOP is reflected as a reduction of stockholders’ equity in the consolidated balance sheet. The difference between the average fair market value and the cost of the shares allocated by the ESOP is recorded as an adjustment to stockholders’ equity. The Company recognized $10,000 and $17,000 in compensation expense for the three months ended September 30, 2021 and September 30, 2020, respectively, and $59,000 and $49,000 for the nine months ended September 30, 2021 and September 30, 2020, respectively. The following table provides the allocated and unallocated shares of common stock associated with the ESOP.

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE 12 – FAIR VALUE MEASUREMENTS ASC Topic 820, Fair Value Measurements and Disclosures The fair value hierarchy prioritizes inputs used to measure fair value into three broad levels. Level 1 inputs – In general, fair values determined by Level 1 inputs use quoted market prices in active markets for identical assets or liabilities that we have the ability to access. Level 2 inputs – Fair values determined by Level 2 inputs use inputs other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets where there are few transactions and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs – Level 3 inputs are unobservable inputs for the asset or liability and include situations where there is little, if any, market activity for the asset or liability. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. Some assets and liabilities, such as securities available-for-sale, Following is a description of the Company’s valuation methodology and significant inputs used for each asset and liability measured at fair value on a recurring or nonrecurring basis. Securities available-for-sale Impaired loans Mortgage servicing rights Assets measured at fair value on a recurring basis are summarized below, along with the level of the fair value hierarchy of the inputs utilized to determine such fair value.

Fair value is best determined based on quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. Consequently, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company. Fair value estimates are made at a specific point in time based on relevant market information and information about the financial instrument. These estimates to not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments and other factors. These estimates are subjective in nature and involve uncertainties and matters that could affect the estimates. Fair value estimates are based on existing on- off-balance-sheet Deposits with no stated maturities are defined as having a fair value equivalent to the amount payable on demand. This prohibits adjusting fair value derived from retaining those deposits for an expected future period of time. This component, commonly referred to as a deposit base intangible, is neither considered in the above amounts, nor is it recorded as an intangible assets on the balance sheets. In addition, the tax ramifications related to the realization of unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates.
