Accounting Policies [Abstract] |
Subsequent Events, Policy [Policy Text Block] | Subsequent Events: The Company has evaluated subsequent events through the filing date of this Quarterly Report on Form 10-Q with the SEC.
Reclassification, Comparability Adjustment [Policy Text Block] | Reclassifications: Certain reclassifications have been made to the prior period’s consolidated financial statements to present them on a basis comparable with the current period’s consolidated financial statements. The reclassifications had no effect on stockholders’ equity and net income of the prior periods.
Goodwill and Intangible Assets, Policy [Policy Text Block] | Goodwill: Goodwill represents the excess of cost over the fair value of net assets acquired. Goodwill resulting from acquisitions is not amortized, but is tested for impairment annually or whenever events change and circumstances indicate that it is more likely than not that an impairment loss has occurred. Goodwill is tested for impairment with an estimation of the fair value of a reporting unit. The fair value of a reporting unit is the price that would be received to sell the unit as a whole in an orderly transaction between market participants at the measurement date. As none of the Company’s reporting units are publicly traded, individual reporting unit fair value determinations cannot be directly correlated to the Company’s stock price. Significant judgment is applied when goodwill is assessed for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions and selecting an appropriate control premium. The Company completed a quantitative assessment of goodwill as of October 1, 2022 which indicated that goodwill was not impaired. Subsequently, the Company determined there were no adverse changes in criteria and key considerations to the previous assessment. Accordingly, the Company concluded there is no impairment of goodwill as of March 31, 2023.
Adoption of New Financial Accounting Standard [Policy Text Block] | Adoption of New Financial Accounting Standard Codification 326 (ASC 326 (CECL)): On January 1, 2023, the Company adopted ASU 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires the recognition of the allowance for credit losses be estimated using the current expected credit loss (CECL) methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet (OBS) credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in leases recognized by a lessor in accordance with Topic 842 on leases. In addition, ASC 326 made changes to the accounting for available-for-sale debt securities. One such change is to require credit losses to be presented as an allowance rather than as a write-down on available-for-sale debt securities management does not intend to sell or believes that it is more likely than not they will be required to sell. The Company adopted ASC 326 using the modified retrospective method for all financial assets measured at amortized cost and OBS credit exposures. Results for reporting periods beginning January 1, 2023 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. The Company recorded a net decrease to retained earnings of $603 thousand as of January 1, 2023 for the cumulative effect of adopting ASC 326, which includes deferred taxes of $188 thousand. The transition adjustment includes a $518 thousand increase to the Allowance for Credit Losses on loans and a $273 thousand increase to the Allowance for Credit Losses on OBS Credit Exposures. The following table illustrates the impact of ASC 326 (amounts in thousands).

Marketable Securities, Policy [Policy Text Block] | Available-For-Sale Debt Securities and the Allowance For Credit Losses On Available-For-Sale Debt Securities: Debt securities that we might not hold until maturity are classified as available for sale ("AFS") and are reported at the fair value in the balance sheet. Fair value measurement is based upon quoted market prices in active markets, if available. If quoted prices in active markets are not available, fair value is measured using pricing models or other model-based valuation techniques such as present value of future cash flows, which consider prepayment assumptions and other factors such as credit losses and market liquidity. Unrealized gains and losses are excluded from earnings and reported, net of tax, in other comprehensive income ("OCI"). Gains and losses on the sale of securities are determined using the specific identification method based on amortized cost and are reflected in results of operation at the time of sale. Interest and dividend income, adjusted by amortization of purchase premium or discount over the estimated life of the security or, in the case of callable securities, through the first call date, using the level yield method, is included in income as earned. AFS debt securities in unrealized loss positions are evaluated for impairment related to credit losses at least quarterly. For AFS debt securities, a decline in fair value due to credit loss results in recording an allowance for credit losses to the extent the fair value is less than the amortized cost basis. Declines in fair value that have not been recorded through an allowance for credit losses, such as declines due to changes in market interest rates, are recorded through other comprehensive income, net of applicable taxes. Impairment may result from credit deterioration of the issuer or collateral underlying the security. In performing an assessment of whether any decline in fair value is due to a credit loss, all relevant information is considered at the individual security level. For asset-backed securities performance indicators considered related to the underlying assets include default rates, delinquency rates, percentage of nonperforming assets, debt-to-collateral ratios, third-party guarantees, current levels of subordination, vintage, geographic concentration, analyst reports and forecasts, credit ratings and other market data. In assessing whether a credit loss exists, we compare the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis for the security, a credit loss exists and an allowance for credit losses is recorded, limited to the amount the fair value is less than amortized cost basis. If we intend to sell a debt security or more likely than not we will be required to sell the security before recovery of its amortized cost basis, the debt security is written down to its fair value and the write down is charged against the allowance for credit losses with any incremental impairment reported in earnings. Accrued interest receivable on AFS debt securities totaled $4.2 million at March 31, 2023 and is excluded from the estimate of credit losses.
Financing Receivable, Held-for-Sale [Policy Text Block] | Loans Held for Sale: Loans held for sale are stated at the lower of aggregate cost or estimated fair value. Loans are sold on a non-recourse basis with servicing released and gains and losses are recognized based on the difference between sales proceeds and the carrying value of the loan. The Company has had very few experiences of repurchasing loans previously sold into the secondary market. A specific reserve was not considered necessary based on the Company’s historical experience with repurchase activity.
Receivable [Policy Text Block] | Loans Held For Investment: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost net of the allowance for credit losses. Amortized cost is the principal balance outstanding, net of deferred loan fees and costs. Accrued interest receivable on loans held for investment totaled $6.3 million at March 31, 2023 and is excluded from the estimate of credit losses. Interest income is accrued on the unpaid principal balance. Nonrefundable loan fees and origination costs are deferred and recognized as a yield adjustment over the life of the related loan. The policy for charging off loans is consistent throughout all loan categories. A loan is charged off based on criteria that includes but is not limited to: delinquency status, financial condition of the entire customer credit line and underlying collateral coverage, economic or external conditions that might impact full repayment of the loan, legal issues, overdrafts, and the customer’s willingness to work with the Company. The accrual of interest income on loans is discontinued when, in the opinion of management, there is reasonable doubt as to the borrower's ability to meet payments of interest or principal when they become due, which is generally when a loan is 90 days or more past due unless the loan is well secured and in the process of collection. When a loan is placed on nonaccrual status, all previously accrued and unpaid interest is reversed against interest income. Loans are returned to an accrual status when all of the principal and interest amounts contractually due are brought current and repayment of the remaining contractual principal and interest is expected. A loan may also return to accrual status if additional collateral is received from the borrower and, in the opinion of management, the financial position of the borrower indicates that there is no longer any reasonable doubt as to the collection of the amount contractually due. Payment received on nonaccrual loans are applied first to principal. Once principal is recovered, any remaining payments received are applied to interest income.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block] | Allowance for Credit Losses For Loans Held For Investment: Credit quality within the loans held for investment portfolio is continuously monitored by management and is reflected within the allowance for credit losses for loans. The allowance for credit losses is an estimate of expected losses inherent within the Company's existing loans held for investment portfolio. Expected credit loss inherent in non-cancelable off-balance-sheet credit exposures is accounted for as a separate liability on the balance sheet. The allowance for credit losses for loans held for investment, as reported in our consolidated balance sheet, is adjusted by a credit loss expense, which is reported in earnings, and reduced by the charge-off of loan amounts, net of recoveries. The loan loss estimation process involves procedures to appropriately consider the unique characteristics of loan portfolio segments which consist of construction real estate, 1 to 4 family residential real estate, multi-family real estate, commercial real estate, agricultural real estate, commercial, agricultural and consumer and other lending. When computing allowance levels, credit loss assumptions are estimated using a model that categorizes loan pools based on loss history, delinquency status and other credit trends and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. The key components in this estimation process include the following:
| ● | An initial forecast period of one year for all portfolio segments and OBS credit exposures. This period reflects management's expectation of losses based on forward-looking economic scenarios over that time.
| ● | A historical loss forecast period covering the remaining contractual life, adjusted for prepayments, by portfolio segment based on the change in key historical economic variables.
| ● | A reversion period of 1 year connecting the initial loss forecast to the historical loss forecast based on economic conditions at the measurement date.
The Company primarily utilizes loss rate based undiscounted cash flow (UDCF) methods to estimate credit losses by portfolio segment. The UDCF methods obtain estimated life-time credit losses using the conceptual components described above. Determining the appropriateness of the allowance is complex and requires judgment by management about the effect of matters that are inherently uncertain. In future periods evaluations of the overall loan portfolio, in light of the factors and forecasts then prevailing, may result in significant changes in the allowance and credit loss expense in those future periods. Credit quality is assessed and monitored by evaluating various attributes and the results of those evaluations are utilized in underwriting new loans and in our process for estimation of expected credit losses. The following provides the credit quality indicators and risk elements that are most relevant and most carefully considered and monitored for each loan portfolio segment. Construction Real Estate – Construction loans are underwritten utilizing independent appraisals, sensitivity analysis of absorption, vacancy and lease rates and financial analysis of the developers and property owners. Construction loans are generally based upon estimates of costs and value associated with the completed project. These estimates may prove to be inaccurate primarily due to unforeseen circumstances beyond the control of the borrower or lender. Construction loans often involve the disbursement of funds with repayment substantially dependent on the success of the ultimate project. These loans are closely monitored by on-site inspections and are considered to have higher risks than other real estate loans due to their ultimate repayment being sensitive to interest rate changes, general economic conditions and the availability of long-term financing. The Company may require guarantees on these loans. The Company’s construction loans are secured primarily by properties located in its primary market area. National unemployment rate is a key economic forecast used in estimating expected credit losses for this segment. 1-4 Family Residential Real Estate – The Company originates 1-4 family real estate loans utilizing credit reports to supplement the underwriting process. The Company’s underwriting standards for 1-4 family loans are generally in accordance with FHLMC and FNMA manual underwriting guidelines. Properties securing 1-4 family real estate loans are appraised by either staff appraisers or fee appraisers, both of which are independent of the loan origination function and have been approved by the Board of Directors. The loan-to-value ratios normally do not exceed 90% without credit enhancements such as mortgage insurance. The Company will lend up to 100% of the lesser of the appraised value or purchase price for conventional 1-4 family real estate loans, provided private mortgage insurance is obtained. The Company’s 1-4 family real estate loans are secured primarily by properties located in its primary market area. The national unemployment rate is a key economic forecast used in estimating expected credit losses for this segment. Multi-family, Commercial and Agricultural Real Estate – Multi-family, commercial and agricultural real estate loans are subject to underwriting standards and processes similar to commercial and agricultural operating loans, in addition to those unique to real estate loans. These loans are viewed primarily as cash flow loans and, secondarily, as loans secured by real estate. Multi-family, commercial and agricultural real estate lending typically involves higher loan principal amounts and the repayment of these loans is generally dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. Loan-to-value generally does not exceed 80% of the cost or value of the assets. Loans are typically subject to interest rate adjustments between five and seven years from origination. Fully amortized monthly repayment terms normally do not exceed twenty-five years. Projections and cash flows that show ability to service debt within the amortization period are required. Property and casualty insurance is required to protect the Banks’ collateral interests. Appraisals on properties securing these loans are generally performed by fee appraisers approved by the Board of Directors. Because payments on multi-family, commercial and agricultural real estate loans are often dependent on the successful operation or management of the properties, repayment of such loans may be subject to adverse conditions in the real estate market or the economy. Management monitors and evaluates commercial and agricultural real estate loans based on collateral and risk rating criteria. The Company may require guarantees on these loans. The Company’s multi-family, commercial and agricultural real estate loans are secured primarily by properties located in its primary market areas. The national unemployment rate and the national real gross domestic product (GDP) are key economic forecasts used in estimating expected credit losses for the multi-family and commercial real estate segments. The national real GDP is a key economic forecast used in estimating expected credit losses for the agricultural real estate segment. Commercial and Agricultural – Commercial and agricultural operating loans are underwritten based on the Company’s examination of current and projected cash flows to determine the ability of the borrower to repay their obligations as agreed. This underwriting includes the evaluation of cash flows of the borrower, underlying collateral, if applicable, and the borrower’s ability to manage its business activities. The cash flows of borrowers and the collateral securing these loans may fluctuate in value after the initial evaluation. A first priority lien on the general assets of the business normally secures these types of loans. Loan-to-value limits vary and are dependent upon the nature and type of the underlying collateral and the financial strength of the borrower. Crop and hail insurance is required for most agricultural borrowers. Loans are generally guaranteed by the principal(s). The Company’s commercial and agricultural operating lending is primarily in its primary market area. The national unemployment rate and the national real GDP are key economic forecasts used in estimating expected credit losses for the commercial operating segment. The national real GDP is a key economic forecast used in estimating expected credit losses for the agricultural operating segment. Consumer and Other – Consumer and other loans utilize credit reports to supplement the underwriting process. The underwriting standards include a determination of the applicant’s payment history on other debts and an assessment of their ability to meet existing obligations and payments on the proposed loan. To monitor and manage loan risk, policies and procedures are developed and modified, as needed by management. This activity, coupled with smaller loan amounts that are spread across many individual borrowers, minimizes risk. Additionally, market conditions are reviewed by management on a regular basis. The Iowa real GDP and Iowa retail trade earnings are key economic forecasts used in estimating expected credit losses for this segment. Determining the Contractual Term: Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals and modifications unless the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by the Company. Credit Loss Measurement: The allowance level is influenced by loan volumes, loan credit quality indicator migration or delinquency status, historic loss experience and other conditions influencing loss expectations, such as reasonable and supportable forecasts of economic conditions. The methodology for estimating the amount of expected credit losses reported in the allowance for credit losses has two basic components: first, an asset-specific component involving individual loans that do not share risk characteristics with other loans and the measurement of expected credit losses for such individual loans; and second, a pooled component for estimated expected credit losses for pools of loans that share similar risk characteristics. For a loan that does not share risk characteristics with other loans, expected credit loss is measured based on net realizable value, that is, the difference between the discounted value of the expected future cash flows, based on the original effective interest rate, and the amortized cost basis of the loan. For these loans, we recognize expected credit loss equal to the amount by which the net realizable value of the loan is less than the amortized cost basis of the loan (which is net of previous charge-offs and deferred loan fees and costs), except when the loan is collateral dependent, that is, when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. In these cases, expected credit loss is measured as the difference between the amortized cost basis of the loan and the fair value of the collateral. The fair value of the collateral is adjusted for the estimated cost to sell if repayment or satisfaction of a loan is dependent on the sale (rather than only on the operation) of the collateral. The fair value of collateral used by the Company is determined by obtaining an observable market price or by obtaining a fair value from an independent, licensed or certified appraiser, using observable market data. This data includes information such as selling price of similar properties and capitalization rates of similar properties sold within the market, expected future cash flows or earnings of the subject property based on current market expectations, and other relevant factors. Each quarter management reviews all collateral-dependent loans on a loan-by-loan basis to determine whether updated appraisals or evaluations are necessary based on loan performance, collateral type and guarantor support. At times, the Company measures the fair value of collateral-dependent loans using appraisals or evaluations with dates prior to one year from the date of review. Third-party appraisals are obtained from a pre-approved list of independent, third-party, local appraisal firms maintained by the credit underwriting department. Approval and addition to the list is based on experience, reputation, character, consistency and knowledge of the respective real estate market. Generally, appraisals are internally reviewed to ensure the quality of the appraisal and the expertise and independence of the appraiser. Once the expected credit loss amount is determined an allowance is provided for equal to the calculated expected credit loss and included in the allowance for credit losses. If the calculated expected credit loss is determined to be permanent or not recoverable, the amount of expected credit loss will be charged off. Factors considered by management in determining if the expected credit loss is permanent or not recoverable include whether management judges the loan to be uncollectible, repayment is deemed to be protracted beyond reasonable time frames, or the loss becomes evident owing to the borrower's lack of assets unless both well-secured and in the process of collection. In estimating the component of the allowance for credit losses for loans that share similar risk characteristics with other loans, such loans are segregated into loan classes. Loans are designated into loan classes based on loans pooled by product types and similar risk characteristics or areas of risk concentration. In determining the allowance for credit losses, we derive an estimated credit loss assumption from a model that categorizes loan pools based on loan type and purpose. This model calculates an expected loss percentage for each loan class by considering the historical loss rate of similar peers. The loss rate factors used to calculate the allowance for credit losses for loans that share similar risk characteristics with other loans are adjusted for differences between the historical period used to calculate historical loss rates and expected conditions over the remaining lives of the loans in the portfolio related to: (1) lending policies and procedures; (2) international, national, regional and local economic business conditions and developments that affect the collectability of the portfolio; (3) the nature and volume of the loan portfolio including the terms of the loans; (4) the experience, depth, and ability of the lending management and other relevant staff; (5) the volume and severity of past due loans and other similar conditions; (6) the quality of our loan review system and (7) the value of underlying collateral for collateralized loans. Additional factors include the existence and effect of any concentrations of credit, and changes in the level of such concentrations and the effect of external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in the existing portfolio. Such factors are used to adjust the historical loss rates so that they reflect management expectation of future conditions based on a reasonable and supportable forecast. To the extent the lives of the loans in the portfolio extend beyond the period for which a reasonable and supportable forecast can be made, the Company reduces, on a straight-line basis over one year, the adjustments so that the model reverts back to the historical loss rates.
Off-Balance-Sheet Credit Exposure, Policy [Policy Text Block] | Allowance for Credit Losses on Off-Balance Sheet Credit Exposures, Including Unfunded Loan Commitments: The Company maintains a separate allowance for credit losses from off-balance-sheet credit exposures, including unfunded loan commitments, which is included in other liabilities. Management estimates the amount of expected losses by calculating a commitment usage factor over the contractual period for exposures that are not unconditionally cancellable by the Company and applying the loss factors used in the allowance for credit loss methodology to the results of the usage calculation to estimate the liability for credit losses related to unfunded commitments for each loan type. No credit loss estimate is reported for off-balance-sheet credit exposures that are unconditionally cancellable by the Company or for undrawn amounts under such arrangements that may be drawn prior to the cancellation of the arrangement. The allowance for credit losses on OBS credit exposures is adjusted as a credit loss expense. Categories of OBS credit exposures correspond to the loan portfolio segments described previously.
New Accounting Pronouncements, Policy [Policy Text Block] | New and Pending Accounting Pronouncements: In March 2023, the FASB issued ASU No. 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using Proportional Amortization Method. The ASU is intended to improve the accounting and disclosures for investments in tax credit structures. It allows reporting entities to elect to adopt for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. The Company is currently evaluating the impact of the ASU on the Company's consolidated financial statements.
