Summary of Significant Accounting Policies (Policies)	9 Months Ended
Dec. 31, 2023
Accounting Policies [Abstract]
Nature of Operations	Nature of Operations—Central Plains Bancshares, Inc. (the “Company”) was formed to serve as the holding company for Home Federal Savings and Loan Association of Grand Island (the “Association”), upon conversion into the stock form of organization, which was completed on October 19, 2023. Accordingly, the unaudited financial statements, as well as other financial information at or prior to October 19, 2023, contained in this Quarterly Report on Form 10-Q relate solely to the consolidated financial results of Home Federal Savings and Loan Association of Grand Island and Subsidiary. The Company completed its stock offering on October 19, 2023. The Company sold 4,130,815 shares of common stock at $10.00 per share in its subscription offering for gross proceeds of approximately $41.3 million. Shares of the Company's common stock began trading on October 20, 2023 on the Nasdaq Capital Market under the trading symbol "CPBI." The consolidated financial statements include the accounts of the Company and the Association, a wholly owned subsidiary. All intercompany balances and transactions have been eliminated in consolidation. The consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States of America (GAAP) as codified in the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC). The Association is a federally chartered stock savings and loan association whose primary business is providing mortgage, consumer, commercial real estate, and commercial loans in the Grand Island, Nebraska area, with additional lending opportunities through the Association’s participation network of banks in Nebraska and other states, and acquiring consumer and commercial deposits to fund these investments. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates—In preparing the 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. Significant estimates that are particularly susceptible to change in the near term relate to the determination of the allowance for loan losses, the determination of the pension liability, as well as the fair value measurements of investment securities. As with any estimate, actual results could differ from those estimates.
Employee Stock Ownership Plan	Employee Stock Ownership Plan—The ESOP shares pledged as collateral are reported as unearned ESOP shares in the Consolidated Statements of Financial Condition. As shares are committed to be released from collateral, the Association reports compensation expense equal to the average market price of the shares during the year, and the shares become outstanding for basic net income per common share computations. Dividends on allocated ESOP shares reduce retained earnings; dividends on unearned ESOP shares reduce the ESOP's debt and accrued interest.
Earnings Per Share	Earnings per Share—Basic earnings per share represents income available to common stockholders divided by the weighted-average number of common shares outstanding during the period. Unallocated ESOP shares are not deemed outstanding for earnings per share calculations. ESOP shares committed to be released are considered to be outstanding for purposes of the earnings per share computation. ESOP shares that have not been legally released, but that relate to employee services rendered during an accounting period (interim or annual) ending before the related debt service payment is made, are considered committed to be released. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustments to income that would result from the assumed issuance.
Accounting Developments	Accounting Developments—In June 2016, the FASB issued Accounting Standards Update (ASU) No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” also known as Current Expected Credit Losses, or CECL. ASU 2016-13 was issued to provide financial statement users with more useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date to enhance the decision making process. The CECL model utilizes a lifetime “expected credit loss” measurement objective for the recognition of credit losses for loans, held-to-maturity securities, and other receivables at the time the financial asset is originated or acquired. The expected credit losses are adjusted each period for changes in expected lifetime credit losses. For available for-sale securities where fair value is less than cost, credit-related impairment, if any, will be recognized in an allowance for credit losses and adjusted each period for changes in expected credit risk. This model replaced the previous existing impairment models, which generally required that a loss be incurred before it is recognized. The Company adopted ASC 326 and all related subsequent amendments thereto effective on April 1, 2023 using the modified retrospective approach for all financial assets measured at amortized cost and off-balance sheet credit exposures. The transition adjustment for the adoption of CECL resulted in an increase in the allowance for credit losses on loans of $299, which is presented as a reduction to net loans outstanding, and the establishment of an allowance for credit losses on unfunded loan commitments of $210, which is recorded within accounts payable, accrued expenses and other liabilities on the consolidated statement of financial condition. The Company recorded a net decrease to retained earnings of $402, as of April 1, 2023, for the cumulative effect of adopting CECL, which reflects the transition adjustments noted above, net of the applicable deferred tax assets recorded. Results for reporting periods beginning after April 1, 2023 are presented under CECL while prior period amounts continue to be reported in accordance with previously applicable accounting standards (“Incurred Loss”). In March 2022, the FASB issued ASU 2022-02, Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The amendments in this update eliminate the accounting guidance and related disclosures for troubled debt restructurings (TDRs) by creditors in Subtopic 310-40, Receivables—Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty and requiring an entity to disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, Financial Instruments—Credit Losses—Measured at Amortized Cost. The Company adopted the amendments in this update on April 1, 2023, and is applying the amendments prospectively with the exception of the recognition and measurement of existing TDRs for which the entity has elected to apply a modified retrospective transition method.
Allowance for Credit Losses	Allowance for Credit Losses The allowance for credit losses (“ACL”) is an estimate of the expected credit losses on the loans held for investment, unfunded loan commitments, held to maturity securities, and available-for-sale debt securities portfolios. Allowance for Credit Losses on Loans—The ACL is maintained by management at a level believed adequate to absorb estimated credit losses that are expected to occur within the existing loan portfolio through their contractual terms adjusted for expected prepayments. The ACL is a valuation account that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on loans. Determination of the ACL is inherently subjective in nature since it requires significant estimates and management judgment, and includes a level of imprecision given the difficulty of identifying and assessing the factors impacting loan repayment and estimating the timing and amount of losses. While management utilizes its best judgment and information available, the ultimate adequacy of the ACL is dependent upon a variety of factors beyond the Company's direct control, including, but not limited to, the performance of the loan portfolio, consideration of current economic trends, changes in interest rates and property values, estimated losses on pools of homogeneous loans based on an analysis that uses historical loss experience for prior periods that are determined to have like characteristics with the current period such as pre-recessionary, recessionary, or recovery periods, portfolio growth and concentration risk, management and staffing changes, the interpretation of loan risk classifications by regulatory authorities and other credit market factors. The ACL methodology consists of measuring loans on a collective (pool) basis when similar risk characteristics exist. The Company has identified seven portfolio segments and measures the ACL using the Scaled CECL Allowance for Losses Estimator (“SCALE”) method. The loan portfolios are real estate – construction, real estate – commercial, real estate – residential, commercial, agriculture, other consumer and land development/sanitary improvement districts (SIDS). The SCALE method uses publicly available data from Schedule RI-C of the Call Report to derive the initial proxy expected lifetime loss rates. These proxy expected lifetime loss rates are then adjusted for Company-specific facts and circumstances to arrive at the final ACL estimate that adequately reflects the Company's loss history and credit risk within our portfolio. The qualitative factors applied to each loan portfolio consist of the impact of other internal and external qualitative and credit market factors as assessed by management through a detailed loan review, ACL analysis and credit discussions. These internal and external qualitative and credit market factors used include the following: • The nature and volume of the Company’s financial assets; • The existence, growth, and effect of any concentration of credit; • The volume and severity of past due financial assets, the volume of nonaccrual assets, and the volume and severity of adversely classified or graded assets; • The value of the underlying collateral for loans that are non-collateral-dependent; • The Company’s lending policies and procedures, including changes in underwriting standards and practices for collections, write-offs, and recoveries; • The quality of the Company’s credit review function; • The experience, ability, and depth of the Company’s lending, investment, collection, and other relevant management and staff; • The effect of other external factors such as the regulatory, legal and technological environments; competition; and events such as natural disasters; and • Actual and expected changes in international, national, regional, and local economic and business conditions and developments in which the Company operates that affect the collectability of financial assets. The impact of the above listed internal and external qualitative and credit market risk factors is assessed within predetermined ranges to adjust the ACL totals calculated. In addition to the pooled analysis performed for the majority of our loan and commitment balances, we also review those loans that have collateral dependency or nonperforming status which requires a specific review of that loan, per our individually analyzed CECL calculations. Loans are charged off against the ACL when management believes the uncollectability of a loan balance is confirmed, while recoveries of amounts previously charged-off are credited to the ACL. Approved releases from previously established ACL reserves authorized under our ACL methodology also reduce the ACL. Additions to the ACL are established through the provision for credit losses on loans, which is charged to expense. The Company’s ACL methodology is intended to reflect all loan portfolio risk, but management recognizes the inability to accurately depict all future credit losses in a current ACL estimate, as the impact of various factors cannot be fully known. Accrued interest receivable on loans is excluded from the amortized cost basis of financing receivables for the purpose of determining the allowance for credit losses. Allowance for Credit Losses on Unfunded Loan Commitments—The Company estimates expected credit losses over the contractual period in which the Company is exposed to credit risk by a contractual obligation to extend credit, unless that obligation is unconditionally cancelable by the Company. The ACL related to off-balance sheet credit exposures, which is recorded within accounts payable, accrued expenses and other liabilities on the consolidated statement of financial condition, is estimated at each balance sheet date under the CECL model, and is adjusted as determined necessary through the provision for credit losses on the consolidated statement of income. The estimate for ACL on unfunded loan commitments includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life. Allowance for Credit Losses on Securities Available-for-Sale—For available-for-sale debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more likely than not that it will sell, the security before recovery of its amortized cost basis. If either of the aforementioned criteria exists, the Company will record an ACL related to securities available-for-sale with an offsetting entry to the provision for credit losses on securities on the income statement. If either of these criteria does not exist, the Company will evaluate the securities individually to determine whether the decline in the fair value below the amortized cost basis (impairment) is due to credit-related factors or noncredit-related factors, such as market interest rate fluctuations. In evaluating securities available-for sale for potential impairment, the Company considers many factors, including the financial condition and near-term prospects of the issuer, which for debt securities considers external credit ratings and recent downgrades; and its ability and intent to hold the security for a period of time sufficient for a recovery in value. The Company also considers the extent to which the securities are issued by the federal government or its agencies, and any guarantee of issued amounts by those agencies. The amount of the impairment related to other factors is recognized in other comprehensive income (loss). Allowance for Credit Losses on Held-to Maturity Securities—The allowance for credit losses on held-to-maturity debt securities is estimated using the CECL methodology. Any expected credit loss is provided through the ACL on held-to-maturity securities and is deducted from the amortized cost basis of the security so that the balance sheet reflects the net amount the Company expects to collect. Nearly all the Company's held-to-maturity debt securities are issued by U.S. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies, and have a long history of no credit losses. Accordingly, there is a zero-credit loss expectation on these securities.
Allowance for Loan Losses (Prior to April 1, 2023)	Allowance for Loan Losses (Prior to April 1, 2023)—The allowance for loan losses represents management’s estimate of probable losses inherent in the loan portfolio. Additions to the allowance are recorded in the provision for loan losses charged to expense. Charge-offs, net of recoveries, are deducted from the allowance. The allowance estimate is based on prior experience, the nature and volume of the loan portfolio, review of specific problem loans, and an evaluation of the overall portfolio quality under current economic conditions. Specific reserves for impaired loans are measured and recognized to the extent that the recorded investment of an impaired loan exceeds its value based on either the fair value of the loan’s underlying collateral less estimated costs to sell, the calculated present value of projected cash flows discounted at the contractual interest rate, or the loan’s observable fair value. The Association’s allowance for loan losses consists of various methodologies to determine impairment: (a) loans individually evaluated for impairment are evaluated based upon a specific identified probable loss, and (b) loans collectively evaluated for impairment are evaluated based on historical loan loss experience for similar loans with similar characteristics, adjusted to reflect the impact of current conditions. Factors considered in determining the adjustment for current conditions include the following: (a) changes in asset quality, (b) composition and concentrations of credit risk, and (c) the impact of economic risks on the portfolio. In determining the allowance for loan losses, management considers factors such as economic and business conditions affecting key lending areas, credit concentrations and credit quality trends. Since the evaluation of the inherent loss with respect to these factors is subject to a higher degree of uncertainty, the measurement of the overall allowance is subject to estimation risk and the amount of actual losses can vary significantly from the estimated amounts. The Association’s measurement methods incorporate comparisons between recent experience and historical rates. Loans are generally secured by underlying real estate, business assets, personal property and personal guarantees. The amount of collateral obtained is based upon management’s evaluation of the borrower. The Association periodically may agree to modify the contractual terms of loans. When a loan is modified and a concession is made to a borrower experiencing financial difficulty, the modification is considered a TDR. A loan is considered impaired when it is probable that all principal and interest amounts due will not be collected in accordance with the loan’s contractual terms. Except for TDRs, consumer loans within any class are generally not individually evaluated on a regular basis for impairment. All TDRs, regardless of the outstanding balance amount, are considered to be impaired. The allowance established for probable losses on specific loans is based on a periodic analysis and evaluation of classified loans. Specific reserves for impaired loans are measured and recognized to the extent that the recorded investment of an impaired loan exceeds its value based on either the fair value of the loan’s underlying collateral less costs to sell, the calculated present value of projected cash flows discounted at the contractual effective interest rate or the loan’s observable fair value.
Cash and Cash Equivalents	Cash and Cash Equivalents—Cash and cash equivalents include cash on hand, federal funds sold, demand deposits at other financial institutions, and short-term investments with maturities of three months or less when purchased.
Investment Securities	Investment Securities—Debt securities that management has the positive intent and ability to hold to maturity are classified as held to maturity and recorded at amortized cost. Securities not classified as held to maturity are classified as available for sale and recorded at fair value, with unrealized gains and losses on a net-of-tax basis excluded from earnings and reported in other comprehensive income. The fair value of a security is determined based on quoted market prices. If quoted market prices are not available, fair value is determined based on quoted market prices of similar instruments or discounted cash flow models that incorporate market inputs and assumptions including discount rates, prepayment speeds, and loss rates. The Association did not have any securities classified as trading at December 31, 2023 or March 31, 2023. Purchased premiums and discounts are amortized and accreted to the earlier of call or maturity of the related security using the effective interest method. Realized gains and losses on the sale of securities are recognized on the specific identification method in the statements of income. For periods prior to April 1, 2023, management monitored securities for other-than-temporary-impairment (OTTI). If the Association intends to sell the security or will more likely than not be required to sell the security before recovery of the entire amortized cost basis, then an OTTI has occurred. However, even if the Association does not intend to sell the security and will not likely be required to sell the security before recovery of its entire amortized cost basis, the Association must evaluate expected cash flows to be received to determine if a credit loss has occurred. In the event of a credit loss, the credit component of the impairment is recorded as a loss in the statement of income and the non-credit component is recognized through other comprehensive income (loss).
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock—As a member of the Federal Home Loan Bank of Topeka (FHLB), the Association is required to maintain an investment in the capital stock of the FHLB. For financial reporting purposes, such stock is carried at cost, which approximates fair value, based on the redemption provisions.
Loans Held for Sale	Loans Held for Sale—Mortgage loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or fair value, as determined by outstanding commitments from investors. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings. Mortgage loans held for sale are generally sold with servicing rights retained. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related mortgage loan sold, which is reduced by the cost allocated to the servicing right. The Association generally locks in the sale price to the purchaser of the mortgage loan at the same time an interest rate commitment is made to the borrower.
Loans	Loans—Loans that management has the intent and ability to hold for the foreseeable future are stated at the amount of unpaid principal less an allowance for loan losses and any deferred fees or costs on originated loans. Interest on loans is calculated by using the simple interest method on daily balances of the principal amount outstanding. The accrual of interest on loans is discontinued when management believes that the borrower may be unable to make payments as scheduled, generally when a loan becomes contractually delinquent for three months or more. When interest accrual is discontinued, all unpaid accrued interest is reversed. Interest income is subsequently recognized only to the extent that cash payments are received in excess of principal due. Loan origination fees and commitment fees offset by certain direct loan origination costs are deferred and recognized over the contractual life of the loan as a yield adjustment.
Mortgage Servicing Rights	Mortgage Servicing Rights—Mortgage servicing rights are established based on the allocated fair value of servicing rights retained on loans originated by the Association and subsequently sold in the secondary market. Mortgage servicing rights are amortized into servicing fees on loans on the consolidated statements of income in proportion to, and over the period of, the estimated net servicing income and are evaluated for impairment based on their fair value. Each class of separately recognized servicing assets subsequently measured using the amortization method are evaluated and measured for impairment. Impairment is determined by stratifying rights into tranches based on predominant characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance, to the extent that fair value is less than the carrying amount of the servicing assets for that tranche. The valuation allowance is adjusted to reflect changes in the measurement of impairment after the initial measurement of impairment. Fair value in excess of the carrying amount of servicing assets for that stratum is not recognized. Mortgage servicing assets are recognized separately when rights are acquired through purchase or through sale of financial assets. Under the servicing assets and liabilities accounting guidance (ASC 860-50), servicing rights resulting from the sale or securitization of loans originated by the Association are initially measured at fair value at the date of transfer. The Association has elected to subsequently measure the mortgage servicing rights using the amortization method. Under the amortization method, servicing rights are amortized in proportion to and over the period of estimated net servicing income. The amortized assets are assessed for impairment or increased obligation based on fair value at each reporting date. Each class of separately recognized servicing assets subsequently measured using the amortization method are evaluated and measured for impairment. Impairment is determined by stratifying rights into tranches based on predominant characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual tranche, to the extent that fair value is less than the carrying amount of the servicing assets for that tranche. The valuation allowance is adjusted to reflect changes in the measurement of impairment after the initial measurement of impairment. Changes in valuation allowances are reported with other noninterest expense on the income statement. Servicing fee income is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. The amortization of mortgage servicing rights is netted against loan servicing fee income.
Premises and Equipment	Premises and Equipment—Office properties and equipment are carried at cost less accumulated depreciation. Depreciation is computed based on the straight-line basis over the estimated useful lives of the assets, which range from 3 to 15 years. Leasehold improvements are amortized over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. Costs incurred for maintenance and repairs are expensed as incurred. Premises and equipment are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of a particular asset may not be recoverable.
Leases	Leases—Lease expense for operating and short-term leases is recognized on a straight-line basis over the lease term. Right-of-use assets represent the Association’s right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of the lease payments over the lease term. When the rate implicit in the lease is unknown, the present value of the lease payments is determined using our incremental borrowing rate based on the FHLB amortizing advance rate, adjusted for the lease term and other factors.
Revenue Recognition	Revenue Recognition—Most of the Association’s revenue is not subject to ASC 606, Revenue from Contracts with Customers, including net interest income, fees related to loans and loan commitments, gain on derivatives, and gain on sales of loans and securities. Under ASC 606, the Association must identify the contract with a customer, identify the performance obligation(s) within the contract, determine the transaction price, allocate the transaction price to the performance obligation(s) within the contract, and recognize revenue when (or as) the performance obligation(s) are satisfied. The core principle under ASC 606 requires the Association to recognize revenue to depict the transfer of services or products to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those services or products recognized as performance obligations are satisfied. The Association generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed; charged either on a periodic basis or based on activity. Since performance obligations are satisfied as services are rendered and the transaction prices are fixed, there is little judgment involved in applying Topic 606 that significantly affects the determination of the amount and timing of revenue from contracts with customers.
Transfer of Financial Assets	Transfer of Financial Assets—Transfers of financial assets are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Association, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Association does not maintain effective control over the transferred assets through an agreement to repurchase them before maturity.
Retirement Plans	Retirement Plans—Pension expense is the net of service and interest cost, return on plan assets, and amortization of gains and losses not immediately recognized. Deferred compensation and supplemental retirement plan expense allocates the benefits over years of service.
Interest Rate Risk	Interest Rate Risk—The Association is engaged principally in originating and investing in first mortgage loans, consumer loans to individuals, agricultural loans and commercial loans to businesses primarily in Grand Island, Nebraska. These loans are funded primarily with short-term liabilities that have interest rates that vary with market rates over time. The earnings of the Association are exposed to interest rate risk largely because of the mismatch between the repricing intervals of its assets and liabilities. To reduce interest rate risk, the Association has employed the strategy of selling a majority of the single family fixed-rate home loans the Association originates into the secondary market. The Association holds any adjustable-rate single family home loans in their portfolio. In addition, the commercial loans the Association originates and maintains in its portfolio are either tied to some variant of Wall Street Journal Prime (WSJP) and adjust as WSJP adjusts or they contain shorter term call dates (typically three or five years) when amortized over longer periods of time. The consumer portfolio has three-to-five-year amortized terms which mitigate long term interest rate exposure in this portfolio.
Income Taxes	Income Taxes—The Company and its subsidiary file consolidated income tax returns. Income taxes are accounted for using an asset and liability method. Deferred tax liabilities or assets are recognized for the estimated future tax effects attributable to operating loss and tax credit carryforwards and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes using the currently enacted tax rates expected to apply in the year in which those temporary differences are expected to be recovered or settled. If needed, a valuation allowance is recorded to reduce deferred tax assets to the amount expected to be realized. The Company recognizes tax benefits only for tax positions that are more likely than not to be sustained upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50% likely to be realized upon settlement. A liability for unrecognized tax benefits is recorded for any tax benefits claimed in tax returns that do not meet these recognition and measurement standards. The Company recognizes both interest and penalties (if applicable) as a component of income tax expense.
Comprehensive Income	Comprehensive Income—Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Certain changes in assets and liabilities, such as unrealized gains and losses on available for sale securities and minimum pension liability adjustments, are reported as a separate component of the equity section of the consolidated statements of financial condition; such items, along with net income, are components of comprehensive income, net of tax.
Financial Instruments and Loan Commitments	Financial Instruments and Loan Commitments—Financial instruments include off-balance-sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded. Instruments, such as standby letters of credit, that are considered financial guarantees are recorded at fair value.

Use of Estimates—In preparing the 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. Significant estimates that are particularly susceptible to change in the near term relate to the determination of the allowance for loan losses, the determination of the pension liability, as well as the fair value measurements of investment securities. As with any estimate, actual results could differ from those estimates.

Earnings per Share—Basic earnings per share represents income available to common stockholders divided by the weighted-average number of common shares outstanding during the period. Unallocated ESOP shares are not deemed outstanding for earnings per share calculations. ESOP shares committed to be released are considered to be outstanding for purposes of the earnings per share computation. ESOP shares that have not been legally released, but that relate to employee services rendered during an accounting period (interim or annual) ending before the related debt service payment is made, are considered committed to be released. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustments to income that would result from the assumed issuance.

Allowance for Credit Losses

The allowance for credit losses (“ACL”) is an estimate of the expected credit losses on the loans held for investment, unfunded loan commitments, held to maturity securities, and available-for-sale debt securities portfolios.

Allowance for Credit Losses on Loans—The ACL is maintained by management at a level believed adequate to absorb estimated credit losses that are expected to occur within the existing loan portfolio through their contractual terms adjusted for expected prepayments. The ACL is a valuation account that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on loans. Determination of the ACL is inherently subjective in nature since it requires significant estimates and management judgment, and includes a level of imprecision given the difficulty of identifying and assessing the factors impacting loan repayment and estimating the timing and amount of losses. While management utilizes its best judgment and information available, the ultimate adequacy of the ACL is dependent upon a variety of factors beyond the Company's direct control, including, but not limited to, the performance of the loan portfolio, consideration of current economic trends, changes in interest rates and property values, estimated losses on pools of homogeneous loans based on an analysis that uses historical loss experience for prior periods that are determined to have like characteristics with the current period such as pre-recessionary, recessionary, or recovery periods, portfolio growth and concentration risk, management and staffing changes, the interpretation of loan risk classifications by regulatory authorities and other credit market factors.

The ACL methodology consists of measuring loans on a collective (pool) basis when similar risk characteristics exist. The Company has identified seven portfolio segments and measures the ACL using the Scaled CECL Allowance for Losses Estimator (“SCALE”) method. The loan portfolios are real estate – construction, real estate – commercial, real estate – residential, commercial, agriculture, other consumer and land development/sanitary improvement districts (SIDS). The SCALE method uses publicly available data from Schedule RI-C of the Call Report to derive the initial proxy expected lifetime loss rates. These proxy expected lifetime loss rates are then adjusted for Company-specific facts and circumstances to arrive at the final ACL estimate that adequately reflects the Company's loss history and credit risk within our portfolio.

The qualitative factors applied to each loan portfolio consist of the impact of other internal and external qualitative and credit market factors as assessed by management through a detailed loan review, ACL analysis and credit discussions. These internal and external qualitative and credit market factors used include the following:

•

The nature and volume of the Company’s financial assets;

•

The existence, growth, and effect of any concentration of credit;

•

The volume and severity of past due financial assets, the volume of nonaccrual assets, and the volume and severity of adversely classified or graded assets;

•

The value of the underlying collateral for loans that are non-collateral-dependent;

•

The Company’s lending policies and procedures, including changes in underwriting standards and practices for collections, write-offs, and recoveries;

•

The quality of the Company’s credit review function;

•

The experience, ability, and depth of the Company’s lending, investment, collection, and other relevant management and staff;

•

The effect of other external factors such as the regulatory, legal and technological environments; competition; and events such as natural disasters; and

•

Actual and expected changes in international, national, regional, and local economic and business conditions and developments in which the Company operates that affect the collectability of financial assets.

The impact of the above listed internal and external qualitative and credit market risk factors is assessed within predetermined ranges to adjust the ACL totals calculated.

In addition to the pooled analysis performed for the majority of our loan and commitment balances, we also review those loans that have collateral dependency or nonperforming status which requires a specific review of that loan, per our individually analyzed CECL calculations.

Loans are charged off against the ACL when management believes the uncollectability of a loan balance is confirmed, while recoveries of amounts previously charged-off are credited to the ACL. Approved releases from previously established ACL reserves authorized under our ACL methodology also reduce the ACL. Additions to the ACL are established through the provision for credit losses on loans, which is charged to expense.

The Company’s ACL methodology is intended to reflect all loan portfolio risk, but management recognizes the inability to accurately depict all future credit losses in a current ACL estimate, as the impact of various factors cannot be fully known. Accrued interest receivable on loans is excluded from the amortized cost basis of financing receivables for the purpose of determining the allowance for credit losses.

Allowance for Credit Losses on Unfunded Loan Commitments—The Company estimates expected credit losses over the contractual period in which the Company is exposed to credit risk by a contractual obligation to extend credit, unless that obligation is unconditionally cancelable by the Company. The ACL related to off-balance sheet credit exposures, which is recorded within accounts payable, accrued expenses and other liabilities on the consolidated statement of financial condition, is estimated at each balance sheet date under the CECL model, and is adjusted as determined necessary through the provision for credit losses on the consolidated statement of income. The estimate for ACL on unfunded loan commitments includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life.

Allowance for Credit Losses on Securities Available-for-Sale—For available-for-sale debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more likely than not that it will sell, the security before recovery of its amortized cost basis. If either of the aforementioned criteria exists, the Company will record an ACL related to securities available-for-sale with an offsetting entry to the provision for credit losses on securities on the income statement. If either of these criteria does not exist, the Company will evaluate the securities individually to determine whether the decline in the fair value below the amortized cost basis (impairment) is due to credit-related factors or noncredit-related factors, such as market interest rate fluctuations.

In evaluating securities available-for sale for potential impairment, the Company considers many factors, including the financial condition and near-term prospects of the issuer, which for debt securities considers external credit ratings and recent downgrades; and its ability and intent to hold the security for a period of time sufficient for a recovery in value. The Company also considers the extent to which the securities are issued by the federal government or its agencies, and any guarantee of issued amounts by those agencies. The amount of the impairment related to other factors is recognized in other comprehensive income (loss).

Allowance for Credit Losses on Held-to Maturity Securities—The allowance for credit losses on held-to-maturity debt securities is estimated using the CECL methodology. Any expected credit loss is provided through the ACL on held-to-maturity securities and is deducted from the amortized cost basis of the security so that the balance sheet reflects the net amount the Company expects to collect. Nearly all the Company's held-to-maturity debt securities are issued by U.S. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies, and have a long history of no credit losses. Accordingly, there is a zero-credit loss expectation on these securities.

Cash and Cash Equivalents

Cash and Cash Equivalents—Cash and cash equivalents include cash on hand, federal funds sold, demand deposits at other financial institutions, and short-term investments with maturities of three months or less when purchased.

Federal Home Loan Bank Stock

Federal Home Loan Bank Stock—As a member of the Federal Home Loan Bank of Topeka (FHLB), the Association is required to maintain an investment in the capital stock of the FHLB. For financial reporting purposes, such stock is carried at cost, which approximates fair value, based on the redemption provisions.

Loans

Loans—Loans that management has the intent and ability to hold for the foreseeable future are stated at the amount of unpaid principal less an allowance for loan losses and any deferred fees or costs on originated loans. Interest on loans is calculated by using the simple interest method on daily balances of the principal amount outstanding. The accrual of interest on loans is discontinued when management believes that the borrower may be unable to make payments as scheduled, generally when a loan becomes contractually delinquent for three months or more. When interest accrual is discontinued, all unpaid accrued interest is reversed. Interest income is subsequently recognized only to the extent that cash payments are received in excess of principal due. Loan origination fees and commitment fees offset by certain direct loan origination costs are deferred and recognized over the contractual life of the loan as a yield adjustment.

Premises and Equipment

Premises and Equipment—Office properties and equipment are carried at cost less accumulated depreciation. Depreciation is computed based on the straight-line basis over the estimated useful lives of the assets, which range from 3 to 15 years. Leasehold improvements are amortized over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. Costs incurred for maintenance and repairs are expensed as incurred. Premises and equipment are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of a particular asset may not be recoverable.

Revenue Recognition

Revenue Recognition—Most of the Association’s revenue is not subject to ASC 606, Revenue from Contracts with Customers, including net interest income, fees related to loans and loan commitments, gain on derivatives, and gain on sales of loans and securities.

Under ASC 606, the Association must identify the contract with a customer, identify the performance obligation(s) within the contract, determine the transaction price, allocate the transaction price to the performance obligation(s) within the contract, and recognize revenue when (or as) the performance obligation(s) are satisfied. The core principle under ASC 606 requires the Association to recognize revenue to depict the transfer of services or products to customers in an amount that reflects the consideration that it expects to be

entitled to receive in exchange for those services or products recognized as performance obligations are satisfied. The Association generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed; charged either on a periodic basis or based on activity. Since performance obligations are satisfied as services are rendered and the transaction prices are fixed, there is little judgment involved in applying Topic 606 that significantly affects the determination of the amount and timing of revenue from contracts with customers.

Retirement Plans

Retirement Plans—Pension expense is the net of service and interest cost, return on plan assets, and amortization of gains and losses not immediately recognized. Deferred compensation and supplemental retirement plan expense allocates the benefits over years of service.

Income Taxes

Income Taxes—The Company and its subsidiary file consolidated income tax returns. Income taxes are accounted for using an asset and liability method. Deferred tax liabilities or assets are recognized for the estimated future tax effects attributable to operating loss and tax credit carryforwards and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes using the currently enacted tax rates expected to apply in the year in which those temporary differences are expected to be recovered or settled. If needed, a valuation allowance is recorded to reduce deferred tax assets to the amount expected to be realized. The Company recognizes tax benefits only for tax positions that are more likely than not to be sustained upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50% likely to be realized upon settlement. A liability for unrecognized tax benefits is recorded for any tax benefits claimed in tax returns that do not meet these recognition and measurement standards. The Company recognizes both interest and penalties (if applicable) as a component of income tax expense.

Financial Instruments and Loan Commitments

Financial Instruments and Loan Commitments—Financial instruments include off-balance-sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded. Instruments, such as standby letters of credit, that are considered financial guarantees are recorded at fair value.
