Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation: The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial reporting and with instructions for Form 10-Q and Regulation S-X. These financial statements include all adjustments (consisting of normal recurring accruals) which in the opinion of management are considered necessary for the fair presentation of the financial position and results of operations for the periods shown. The Company considers that it operates as one business segment, a commercial bank. Operating results for the three month period ended March 31, 2024 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2024. For further information, refer to the consolidated financial statements and footnotes thereto included in the Form 10-K Annual Report of Hills Bancorporation and subsidiary (the “Company”) for the year ended December 31, 2023 filed with the Securities Exchange Commission on March 5, 2024. The consolidated balance sheet as of December 31, 2023, has been derived from the audited consolidated financial statements for that period. The Company evaluated subsequent events through the filing date of its quarterly report on Form 10-Q with the SEC. Accounting Estimates: The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Certain Significant Estimates: The allowance for credit losses, fair values of securities and other financial instruments, and share-based compensation expense involve certain significant estimates made by management. These estimates are reviewed by management routinely and it is reasonably possible that circumstances that exist at March 31, 2024 may change in the near-term and the effect could be material to the consolidated financial statements. Actual amounts and values as of the balance sheet dates may be materially different than the amounts and values reported due to the inherent uncertainty in the estimation process. Revenue Recognition: Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers ("ASC 606"), establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the Company’s contracts to provide goods or services to customers. The core principle requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those goods or services recognized as performance obligations are satisfied. The majority of the Company’s revenue-generating transactions are not subject to ASC 606, including revenue generated from financial instruments, such as loans, letters of credit and investment securities. Interest income on loans and investment securities is recognized on the accrual method in accordance with written contracts. Descriptions of the Company’s revenue-generating activities that are within the scope of ASC 606 are the following: Service charges and fees on deposit accounts represent general service fees for monthly account maintenance and activity- or transaction-based fees and consist of transaction-based revenue which includes interchange income, time-based revenue (service period), item-based revenue or some other individual attribute-based revenue. Revenue is recognized when the Company’s performance obligation is completed which is generally monthly for account maintenance services or when a transaction has been completed (such as a wire transfer). Payment for such performance obligations are generally received at the time the performance obligations are satisfied. Trust income represents monthly fees due from wealth management customers as consideration for managing the customers' assets. Wealth management and trust services include custody of assets, investment management, fees for trust services and similar fiduciary activities. Revenue is recognized when our performance obligation is completed each month, which is generally the time that payment is received. A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration (resulting in a contract receivable) or before payment is due (resulting in a contract asset). A contract liability balance is an entity's obligation to transfer a service to a customer for which the entity has already received payment (or payment is due) from the customer. As of March 31, 2024 and December 31, 2023, the Company did not have any significant contract balances. An entity is required to capitalize, and subsequently amortize into expense, certain incremental costs of obtaining a contract with a customer if these costs are expected to be recovered. The incremental costs of obtaining a contract are those costs that an entity incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained (for example, sales commission). The Company utilizes the practical expedient which allows entities to immediately expense contract acquisition costs when the asset that would have resulted from capitalizing these costs would have been amortized in one year or less. The Company has not incurred or capitalized any contract acquisition costs as of March 31, 2024 and December 31, 2023. Tax credit real estate : Tax credit real estate represents three multi-family rental properties, three assisted living rental properties, a multi-tenant rental property for persons with disabilities, and a multi-family senior living rental property, all of which are affordable housing projects as of March 31, 2024. The Company has a 99% or greater limited partnership interest in each limited partnership. The investment in each was completed after the projects had been developed by the general partner. On a regular basis, the Company evaluates recoverability of the carrying value of the tax credit real estate investments to determine if an allowance for credit losses is necessary. The allowance for credit losses is measured by a comparison of the carrying amount of the investments to the future undiscounted cash flows expected to be generated by the investment properties, including the low-income housing tax credits and any estimated proceeds from eventual disposition. If there is an indication of impairment, the allowance for credit losses would be established with a charge to credit loss expense. There were no indications of impairment based on management's evaluation and therefore no allowance for credit losses was determined necessary as of March 31, 2024. Depreciation expense is provided on a straight-line basis over the estimated useful life of the assets. Expenditures for normal repairs and maintenance are charged to expense as incurred. The investments in tax credit real estate are recorded for all years presented using the equity method of accounting, with the exception of the investment in the affordable housing project described below. The operations of the properties are not expected to contribute significantly to the Company’s income before income taxes. However, the properties do contribute in the form of income tax credits, which lowers the Company’s effective tax rate. Once established, the credits on each property last for ten years and are passed through from the limited partnerships to the Company and reduces the consolidated federal tax liability of the Company. In February 2021, the Company provided construction financing and contributed capital of $4.18 million to Del Ray Ridge LP, as limited partner, which owns and operates an affordable housing property in Iowa City, Iowa. The Company accounts for the investment in this tax credit real estate using the proportional amortization method as provided for under Accounting Standards Codification (ASC) 323-740. The investment qualifies for the proportional amortization method as it meets all of the criteria under ASC 323-740-25-1. Substantially all of the projected benefits are from tax credits and other tax benefits due to the minimum buyout clause included in the partnership agreement. Available-for-sale debt securities and the allowance for credit losses on available-for-sale debt securities : Available-for-sale ("AFS") securities consist of debt securities not classified as trading or held to maturity. Available-for-sale securities are stated at fair value, and unrealized holding gains and losses, net of the related deferred tax effect, are reported as a separate component of stockholders' equity. There were no trading or held to maturity securities as of March 31, 2024 or 2023. 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"). Premiums on debt securities are amortized to the earliest call date and discounts on debt securities are accreted over the period to maturity of those securities. The method of amortization results in a constant effective yield on those securities (the interest method). Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. 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 $5.02 million at March 31, 2024 and is excluded from the estimate of credit losses. 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. 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 ("ACL"). Amortized cost is the principal balance outstanding, net of deferred loan fees and costs. Accrued interest receivable on loans held for investment totaled $16.84 million at March 31, 2024 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 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. 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. Allowance for credit losses for loans held for investment : The allowance for credit losses is an estimate of the expected losses over the remaining life of the Company's existing loans held for investment portfolio. 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 agricultural, 1 to 4 family first and junior liens, commercial, and consumer lending. These segments are further disaggregated into loan classes, the level at which credit risk is monitored. For each of these pools, the Company generates cash flow projections at the instrument level wherein payment expectations are adjusted for estimated prepayment speed, curtailments, time to recovery, probability of default, and loss given default. The modeling of expected prepayment speeds, curtailment rates, and time to recovery are based on historical internal data. 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. Agricultural - Agricultural operating loans include loans made to finance agricultural production and other loans to farmers and farming operations. Agricultural loans also include mortgage loans secured by farmland. Agricultural operating loans, most of which are secured by crops and machinery, are provided to finance capital improvement and farm operations as well as acquisitions of livestock and machinery. The ability of the borrower to repay may be affected by many factors outside of the borrower’s control including adverse weather conditions, loss of livestock due to disease or other factors, declines in market prices for agricultural products and the impact of government regulations. The ultimate repayment of agricultural operating loans is dependent upon the profitable operation or management of the agricultural entity. Agricultural operating loans generally have a term of one year and may have a fixed or variable rate. Mortgage loans secured by farmland are made to individuals and businesses within the Company's trade area. The primary source of repayment is the cash flow generated by the collateral underlying the loan. The secondary repayment source would be the liquidation of the collateral. Terms for real estate loans secured by farmland range from one to ten years with an amortization period of 25 years or less. Generally, interest rates are fixed for mortgage loans secured by farmland. Key economic forecasts used in estimating expected credit losses for this segment include the Iowa unemployment rate and the Iowa real gross domestic product (GDP). 1 to 4 Family First and Junior Liens - The 1 to 4 family first and junior liens portfolio segment is comprised of the single family and home equity loan classes, which are underwritten after evaluating a borrower's capacity to repay, credit, and collateral. Several factors are considered when assessing a borrower's capacity, including the borrower's employment, income, current debt, assets, and level of equity in the property. Credit refers to how well a borrower manages their current and prior debts as documented by a credit report that provides credit scores and the borrower's current and past information about their credit history. Collateral refers to the type and use of property, occupancy, and market value. Property appraisals are obtained to assist in evaluating collateral. Loan-to-property value and debt-to-income ratios, loan amount, and lien position are also considered in assessing whether to originate a loan. These borrowers are particularly susceptible to downturns in economic trends such as conditions that negatively affect housing prices and demand and levels of unemployment. Key economic forecasts used in estimating expected credit losses for this segment include the Iowa unemployment rate and the all-transactions house price index for Iowa. Commercial - The commercial loan portfolio segment is comprised of the commercial real estate mortgage including obligations of states and political subdivisions, multifamily residential mortgage, construction/land development and commercial and financial loan classes, whose underwriting standards consider the factors described for single family and home equity loan classes as well as others when assessing the borrower's and associated guarantors or other related party's financial position. These other factors include assessing liquidity, the level and composition of net worth, leverage, considering all other lender amounts and position, an analysis of cash expected to flow through the obligors including the outflow to other lenders, vacancies and prior experience with the borrower. This information is used to assess adequate financial capacity, profitability, and experience. Ultimate repayment of these loans is sensitive to interest rate changes, general economic conditions, liquidity, and availability of long-term financing. Key economic forecasts used in estimating expected credit losses for this segment include the Iowa unemployment rate, the all-transactions house price index for Iowa and the Iowa real GDP. Consumer Lending - The Company offers consumer loans to individuals including personal loans and automobile loans. These consumer loans typically have shorter terms, lower balances, higher yields and higher risks of default than real estate-related loans. Consumer collections are dependent on the borrower's continuing financial stability and are more likely to be affected by adverse personal circumstances. Collateral for these loans generally includes automobiles, boats, recreational vehicles and real estate. However, depending on the overall financial condition of the borrower, some loans are made on an unsecured basis. The collateral securing these loans may depreciate over time, may be difficult to recover and may fluctuate in value based on condition. Key economic forecasts used in estimating expected credit losses for this segment include the Iowa unemployment rate and the Iowa real GDP. 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, a pooled component for estimated expected credit losses for pools of loans that share similar risk characteristics; and second, 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. Depending on the nature of the pool of financial assets with similar risk characteristics, the Company uses a discounted cash flow method or remaining life method to estimate expected credit losses. Discounted cash flow method : 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 probability of default, using life-of-loan analysis periods for all loan segments, and the historical severity of loss, based on the aggregate net lifetime losses incurred per loan class. The default and severity 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 default and loss severity 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, ability, and depth of the lending management and other relevant staff; (5) the volume and severity of past due and adversely classified or graded loans and the volume of nonaccrual loans; (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 probabilities of default and severity of loss so that they reflect management expectation of future conditions based on a reasonable and supportable forecast. The Company uses regression analysis of historical internal and peer data to determine which variables are best suited to be economic variables utilized when modeling lifetime probability of default and loss given default. This analysis also determines how expected probability of default and loss given default will react to forecasted levels of the economic variables. For all DCF models, management has determined that four quarters represents a reasonable and supportable forecast period and reverts back to a historical loss rate over twelve quarters on a straight-line basis. Other internal and external indicators of economic forecasts are also considered by management when developing the forecast metrics. Remaining life method: Expected credit losses for credit cards and overdrafts are determined through use of the remaining life method. The remaining life method utilizes average annual charge-off rates and remaining life to estimate the allowance for credit losses. This is done by estimating the amount and timing of principal payments expected to be received as payment for the balance outstanding as of the reporting period and applying those principal payments against the balance outstanding as of the reporting period along with the average annual charge-off rate until the expected payments have been fully allocated. Collateral dependent financial assets : 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 Company’s estimate of the ACL reflects losses expected over the contractual life of the assets, adjusted for estimated prepayments or curtailments. The contractual term does not consider extensions, renewals or modifications unless the Company has identified a modification including a concession to a borrower experiencing financial difficulties. A modification of a loan to a borrower experiencing financial difficulties occurs when two conditions are met: 1) the borrower is experiencing financial difficulty and 2) concessions are made for the borrower's benefit that would not otherwise be considered for a borrower or transaction with similar credit risk characteristics. 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 disclosed on the balance sheet. 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 ACL 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 (OBS) credit exposures that are unconditionally cancellable by the Company, such as credit card receivables, 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 credit loss expense. Categories of OBS credit exposures correspond to the loan portfolio segments described previously. Effect of New Financial Accounting Standards: In March 2022, the FASB issued ASU 2022-02, Financial Instruments - Credit Losses (Topic 326) Troubled Debt Restructurings and Vintage Disclosures . The FASB issued these amendments to eliminate accounting guidance for 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 to require that an entity disclose current-period gross writeoffs 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 amendments in this Update are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, and should be applied prospectively, except as provided in the next sentence. For the transition method related to the recognition and measurement of TDRs, an entity has the option to apply a modified retrospective transition method, resulting in a cumulative-effect adjustment to retained earnings in the period of adoption. Early adoption is permitted if an entity has adopted the amendments in Update 2016-03, including adoption in an interim period. The adoption of the ASU on a prospective basis by the Company on January 1, 2023 did not have a material impact on the financial statements, however it resulted in new disclosures. In March 2023, the FASB issued ASU 2023-02, Investments - Equity Method and Joint Ventures (Topic 323) Accounting for Investments in Tax Credit Structures Using Proportional Amortization Method . The FASB is issuing this ASU to allow reporting entities to consistently account for equity investments made primarily for the purposes of receiving income tax credits and other income tax benefits. The ASU permits reporting entities to elect to account for tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted for all entities in any interim period. If an entity adopts the amendments in an interim period, it shall adopt them as of the beginning of the fiscal year that includes that interim period. The adoption of the ASU on a prospective basis by the Company on January 1, 2024 did not have a material impact on the financial statements. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) Improvements to Reportable Segment Disclosures . The FASB is issuing this ASU to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. A public entity should apply the amendments in this Update retrospectively to all prior periods presented in the financial statements. Upon transition, the segment expense categories and amounts disclosed in the prior periods should be based on the significant segment expense categories identified and disclosed in the period of adoption. The Company is in the process of evaluating the impact of this ASU on the financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) Improvements to Income Tax Disclosures . The FASB is issuing this ASU to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this ASU require that public business entities on an annual basis disclose specific categories in the rate reconciliation, provide additional information for reconciling items that meet

None of the unrealized losses in the above table was due to the deterioration in the credit quality of any of the issues that might result in the non-collection of contractual principal and interest. The unrealized losses are due to changes in interest rates. The Company has not recognized any unrealized loss in income because management does not have the intent to sell the securities included in the previous table. Management has concluded that it is more likely than not that the Company will not be required to sell these securities prior to recovery of the amortized cost basis. The securities are of high credit quality (investment grade credit ratings) and principal and interest payments are made timely with no payments past due as of March 31, 2024. The fair value is expected to recover as the securities approach maturity. The U.S. Treasury and other securities are issued and guaranteed by U.S. government-sponsored entities and agencies. The MBS and CMOs have implied U.S. government guarantees of the agency securities. The Company evaluates if a credit loss exists by monitoring to ensure it has adequate credit support considering the nature of the investment, number and significance of investments in an unrealized loss position, collectability or delinquency issues, the underlying financial statements of the issuers, credit ratings and subsequent changes thereto, and other available relevant information. Considering the above factors, management has determined that no allowance for credit losses is necessary for the securities portfolio as of March 31, 2024.

Management regularly reviews loans in the portfolio to assess credit quality indicators and to determine appropriate loan classification and grading in accordance with applicable bank regulations. The Company's risk rating methodology assigns risk ratings ranging from 1 to 6, where a higher rating represents higher risk. The Company differentiates its lending portfolios into loans sharing common risk characteristics for which expected credit loss is measured on a pool basis and loans not sharing common risk characteristics for which credit loss is measured individually. The below are descriptions of the credit quality indicators: Excellent – Excellent rated loans are prime quality loans covered by highly liquid collateral with generous margins or supported by superior current financial conditions reflecting substantial net worth, relative to total credit extended, and based on assets of a stable and non-speculative nature whose values can be readily verified. Identified repayment source or cash flow is abundant and assured. Loans are secured with cash, cash equivalents, or collateral with very low loan to values. The borrower would qualify for unsecured debt and guarantors provide excellent secondary support to the relationship. The borrower has a long-term relationship with the Company, maintains high deposit balances and has an established payment history with the Company and an established business in an established industry. Good – Good rated loans are adequately secured by readily marketable collateral or good financial condition characterized by liquidity, flexibility and sound net worth. Loans are supported by sound primary and secondary payment sources and timely and accurate financial information. The relationship is not quite as strong as a borrower that is assigned an excellent rating but still has a very strong liquidity position, low leverage, and track record of strong performance. These loans have a strong collateral position with limited risk to bank capital. The collateral will not materially lose value in a distressed liquidation. Guarantors provide additional secondary support to mitigate possible bank losses. The borrower has a long-term relationship with the Company with an established track record of payments; loans with shorter remaining loan amortization; deposit balances are consistent; loan payments could be made from cash reserves in the interim period; and source of income is coming from a stable industry. Satisfactory – Satisfactory rated loans are loans to borrowers of average financial means not especially vulnerable to changes in economic or other circumstances, where the major support for the extension is sufficient collateral of a marketable nature, and the primary source of repayment is seen to be clear and adequate. The borrower's financial performance is consistent, ratios and trends are positive and the primary repayment source can clearly be identified and supported with acceptable financial information. The loan relationship could be vulnerable to changes in economic or industry conditions but have the ability to absorb unexpected issues. The loan collateral coverage is considered acceptable and guarantors can provide financial support but net worth might not be as liquid as a 1 or 2 rated relationship. The borrower has an established relationship with the Company. The relationship is making timely loan payments, any operating line is revolving and deposit balances are positive with limited to no overdrafts. Management and industry is considered stable. Monitor – Monitor rated loans are identified by management as warranting special attention for a variety of reasons that may bear on ultimate collectability. This may be due to adverse trends, a particular industry, loan structure, or repayment that is dependent on projections, or a one-time occurrence . The relationship l iquidity levels are minimal and the borrower’s leverage position is brought into question. The primary repayment source is showing signs of being stressed or is not proven. If the borrower performs as planned, the loan will be repaid. The collateral coverage is still considered acceptable but there might be some concern with the type of real estate securing the debt or highly dependent on chattel assets. Some loans may be better secured than others. Guarantors still provide some support but there is not an abundance of financial strength supporting the guaranty. A monitor credit may be appropriate when the borrower is experiencing rapid growth which is impacting liquidity levels and increasing debt levels. Other attributes to consider would include if the business is a start-up or newly acquired, if the relationship has significant financing relationships with other financial institutions, the quality of financial information being received, management depth of the company, and changes to the business model. The track history with the Company has some deficiencies such as slow payments or some overdrafts. Special Mention – Special mention rated loans are supported by a marginal payment capacity and are marginally protected by collateral. There are identified weaknesses that if not monitored and corrected may adversely affect the Company’s credit position. A special mention credit would typically have a weakness in one of the general categories (cash flow, collateral position or payment history) but not in all categories. Potential indicators of a special mention would include past due payments, overdrafts, management issues, poor financial performance, industry issues, or the need for additional short-term borrowing. The ability to continue to make payments is in question; there are “red flags” such as past due payments, non-revolving credit lines, overdrafts, and the inability to sell assets. The borrower is experiencing delinquent taxes, legal issues, etc., obtaining financial information has become a challenge, collateral coverage is marginal at best, and the value and condition could be brought into question. Collateral document deficiencies have been noted and if not addressed, could become material. Guarantors provide minimal support for this relationship. The credit may include an action plan or follow up established in the asset quality process. There is a change in the borrower’s communication pattern. Industry issues may be impacting the relationship. Adverse credit scores or history of payment deficiencies could be noted. Substandard – Substandard loans are not adequately supported by the paying capacity of the borrower and may be inadequately collateralized. These loans have a well-defined weakness or weaknesses. Full repayment of the loan(s) according to the original terms and conditions is in question or not expected. For these loans, it is more probable than not that the Company could sustain some loss if the deficiency(ies) is not corrected. There are identified shortfalls in the primary repayment source such as carry over debt, past due payments, and overdrafts. Obtaining quality and timely financial information is a weakness. The loan is under secured with exposure that could impact the Company's capital. It appears the liquidation of collateral has become the repayment source. The collateral may be difficult to foreclose or have little to no value. Collateral documentation deficiencies have been noted during the review process. Guarantor(s) provide minimal to no support of the relationship. The borrower’s communication with the Company continues to decrease and the borrower is not addressing the situation. There is some concern about the borrower’s ability and willingness to repay the loans. Problems may be the result of external issues such as economic or industry related issues.

Certain nonaccrual loan information by loan type at March 31, 2024 and December 31, 2023, was as follows: March 31, 2024 December 31, 2023 Non-accrual Accruing loans Non- Accruing loans (Amounts In Thousands) (Amounts In Thousands) Agricultural $ 279 $ — $ — $ — Commercial and financial 493 — 524 — Real estate: Construction, 1 to 4 family residential 5,242 — 5,505 — Construction, land development and commercial 6,993 — 8,049 30 Mortgage, farmland — — — — Mortgage, 1 to 4 family first liens 6,008 129 5,805 515 Mortgage, 1 to 4 family junior liens 259 — 221 — Mortgage, multi-family 7,576 — 7,685 — Mortgage, commercial 3,277 — 3,099 — Loans to individuals — — — — Obligations of state and political subdivisions — — — — $ 30,127 $ 129 $ 30,888 $ 545 Loans 90 days or more past due that are still accruing interest decreased $0.42 million from December 31, 2023 to March 31, 2024. As of March 31, 2024, there was 1 accruing loan past due 90 days or more with an average loan balance of $0.13 million. There were 7 accruing loans past due 90 days or more as of December 31, 2023 with an average loan balance of $0.08 million. The accruing loans past due 90 days or more balances are believed to be adequately collateralized and the Company expects to collect all principal and interest as contractually due under these loans. There was no interest income recognized on nonaccrual loans for the three months ended March 31, 2024 and year ended December 31, 2023. As of March 31, 2024, nonaccrual loans had no ACL allocation recorded except for $0.08 million recorded for 1 to 4 family first lien mortgages, $0.05 million for commercial mortgages and $0.01 million for agricultural loans. As of December 31, 2023, nonaccrual loans had no ACL allocation recorded except for $0.10 million recorded for 1 to 4 family first lien mortgages. The allowance for credit losses incorporates an estimate of lifetime expected credit losses and is recorded on each asset upon asset origination or acquisition. The starting point for the estimate of the allowance for credit losses is historical loss information, which includes losses from modifications of receivables to borrowers experiencing financial difficulty. An assessment of whether a borrower is experiencing financial difficulty is made on the date of a modification. Because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses because of the measurement methodologies used to estimate the allowance, a change to the allowance for credit losses is generally not recorded upon modification. In some cases, the Company will modify a certain loan by providing multiple types of concessions. Typically, one type of concession, such as a term extension, is granted initially. If the borrower continues to experience financial difficulty, another concession, such as principal forgiveness, may be granted. The following table shows the amortized cost basis at the end of the reporting period of the loans modified to borrowers experiencing financial difficulty, disaggregated by class of financing receivable and type of concession granted (numbers in thousands): Loan Modifications Made to Borrowers Experiencing Financial Difficulty March 31, 2024 March 31, 2023 Amortized Cost Basis % of Total Class of Financing Receivable Amortized Cost Basis % of Total Class of Financing Receivable Loan Type Mortgage, farmland $ 2,274 6 month payment deferral 0.80% $ 1,236 Term extension 0.46% Agricultural — None —% 176 Term extension 0.17% Mortgage, commercial 436 Interest only 4 months 0.10% — None —% Commercial and financial 417 Term extension 0.13% — None —% Total $ 3,127 $ 1,412 The following table describes the financial effect of the modifications made to borrowers experiencing financial difficulty: March 31, 2024 March 31, 2023 Loan Type Financial Effect Loan Type Financial Effect Mortgage, farmland Provided a payment deferral, which temporarily reduced monthly payment amounts for the borrowers. Mortgage, farmland Added a weighted-average 4.6 years to the life of loans, which reduced monthly payment amounts for the borrowers. Agricultural None Agricultural Added a weighted-average 0.5 year to the life of loans, which reduced monthly payment amounts for the borrowers. Mortgage, commercial Provided interest only payments, which temporarily reduced monthly payment amounts for the borrowers. Mortgage, commercial None Commercial and financial Added a weighted-average 0.73 year to the life of loans, which reduced monthly payment amounts for the borrowers. Commercial and financial None Upon the Company's determination that a modified loan (or portion of a loan) has subsequently been deemed uncollectible, the loan (or a portion of the loan) is written off. Therefore, the amortized cost basis of the loan is reduced by the uncollectible amount and the allowance for credit losses is adjusted by the same amount. There were no financing receivables that had a payment default during the period and were modified in the 12 months before default to borrowers experiencing financial difficulty as of March 31, 2024 and for the three months ending March 31, 2023. The Company closely monitors the performance of the loans that are modified to borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts. The following table depicts the performance of loans that have been modified in the last 12 months (numbers in thousands): March 31, 2024 Payment Status (Amortized Cost Basis) Current 30-89 Days Past Due 90+ Days Past Due Loan Type Mortgage, farmland $ 2,274 $ — $ — Agricultural 2,497 — — Mortgage, commercial 312 436 — Commercial and financial 417 — — $ 5,500 $ 436 $ — March 31, 2023 Payment Status (Amortized Cost Basis) Current 30-89 Days Past Due 90+ Days Past Due Loan Type Mortgage, Farmland $ 1,236 $ — $ — Agricultural 176 — — $ 1,412 $ — $ — The following table presents the amortized cost basis of collateral dependent loans, by the primary collateral type, which are individually evaluated to determine expected credit losses, and the related ACL allocated to these loans: Primary Type of Co

Leases [Abstract]
Leases	Leases The Bank leases certain of its branch offices, parking facilities and certain equipment under operating leases. The leases have remaining lease terms of 1 year to 10 years, some of which include options to extend the leases for up to 10 years, and some of which include options to terminate the leases within 1 year. As the options are reasonably certain to be exercised, they are recognized as part of the right-of-use assets and lease liabilities. For the three months ended March 31, 2024 and 2023, total operating lease expense was $0.12 million and $0.14 million respectively, and is included in occupancy expenses in the consolidated statements of income. Included in this for the three months ended March 31, 2024 and 2023 were $0.10 million and $0.12 million, respectively, of operating lease costs, $0.01 million and $0.01 million, respectively, of short term lease costs, and $0.01 million and $0.01 million, respectively, of variable lease costs. For the three months ended March 31, 2024 and 2023, cash paid for amounts included in the measurement of operating lease liabilities was $0.10 million and $0.12 million, respectively. As of March 31, 2024 and December 31, 2023, operating lease right-of-use assets included in other assets was $2.06 million and $2.13 million respectively. Operating lease liabilities included in other liabilities were $2.16 million and $2.22 million as of March 31, 2024 and December 31, 2023. As of March 31, 2024 and December 31, 2023, the weighted average remaining lease term for operating leases was 8.36 years and 8.56 years, respectively, and the weighted average discount rate for operating leases was 3.68% and 3.69%, respectively. Discount rates used were determined from FHLB borrowing rates for comparable terms. As of March 31, 2024, maturities of lease liabilities were as follows: Year ending December 31: (Amounts In Thousands) 2024 (excluding the three months ended March 31, 2024) $ 248 2025 332 2026 335 2027 333 2028 295 Thereafter 984 Total lease payments 2,527 Less imputed interest (366) Total operating lease liabilities $ 2,161

(1) Considered Level 2 under ASC 820. (2) Considered Level 3 under ASC 820 and are based on valuation models that use significant assumptions that are not observable in an active market. Fair value of financial instruments : FASB ASC 820, Fair Value Measurements and Disclosures (“ASC 820”) provides a single definition for fair value, a framework for measuring fair value and expanded disclosures concerning fair value. Fair value is defined under ASC 820 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company determines the fair market value of its financial instruments based on the fair value hierarchy established in ASC 820. There are three levels of inputs that may be used to measure fair value as follows: Level 1 Quoted prices in active markets for identical assets or liabilities. Level 2 Observable inputs other than quoted prices included within Level 1. Observable inputs include the quoted prices for similar assets or liabilities in markets that are not active and inputs other than quoted prices that are observable for the asset or liability. Level 3 Unobservable inputs supported by little or no market activity for financial instruments. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. It is the Company’s policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements. The Company is required to use observable inputs, to the extent available, in the fair value estimation process unless that data results from forced liquidations or distressed sales. The following is a description of valuation methodologies used for assets and liabilities recorded at fair value. ASSETS Investment securities available for sale : Investment securities available for sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted prices, if available. If a quoted price is not available, the fair value is obtained from benchmarking the security against similar securities. U.S. Treasury securities are considered Level 1 with the remaining securities considered Level 2. The pricing for investment securities is obtained from an independent source. There are no Level 3 investment securities owned by the Company. The Company obtains an understanding of the independent source’s valuation methodologies used to determine fair value by level of security. The Company validates assigned fair values on a sample basis using an additional third-party provider pricing service to determine if the fair value measurement is reasonable. Due to the nature of our investment portfolio, we do not expect significant and unusual fluctuations as fair value changes primarily relate to interest rate changes. No unusual fluctuations were identified during the three months ended March 31, 2024. If a fluctuation requiring investigation was identified, the Company would research the change with the independent source or other available information. Individually analyzed loans under ASC 326 CECL : See Note 1 for further discussion of individually analyzed loans under CECL. A loan is considered to be non-performing when it is probable that all of the principal and interest due may not be collected according to its contractual terms. Generally, when a loan is considered non-performing, the amount of reserve is measured based on the fair value of the underlying collateral. The Company makes such measurements on all material loans deemed non-performing using the fair value of the collateral for collateral dependent loans or based on the present value of the estimated future cash flows of interest and principal discounted at the loans effective interest rate or the fair value of the loan if determinable. The fair value of collateral used by the Company is determined by obtaining an observable market price or by obtaining an appraised 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. All appraised values are adjusted for market-related trends based on the Company's experience in sales and other appraisals of similar property types as well as estimated selling costs. These loans are considered Level 3 as the instruments used to determine fair market value require significant management judgment and estimation. Foreclosed assets : The Company does not record foreclosed assets at fair value on a recurring basis. Foreclosed assets consist mainly of other real estate owned but may include other types of assets repossessed by the Company. Foreclosed assets are adjusted to the lower of carrying value or fair value less the cost of disposal. Fair value is generally based upon independent market prices or appraised values of the collateral, and may include a marketability discount as deemed necessary by management based on its experience with similar types of real estate. The value of foreclosed assets is evaluated periodically as a nonrecurring fair value adjustment. Foreclosed assets are classified as Level 3. Off-balance sheet instruments : Fair values for outstanding letters of credit are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties' credit standing. The fair value of the outstanding letters of credit is not significant. Unfunded loan commitments are not valued since the loans are generally priced at market at the time of funding (Level 2). Interest rate swap agreements : The fair value is estimated using forward-looking interest rate curves and is calculated using discounted cash flows that are observable or that can be corroborated by observable market data (Level 2). Assets and Liabilities Recorded at Fair Value on a Recurring Basis The table below represents the balances of assets and liabilities measured at fair value on a recurring basis: March 31, 2024 Readily Observable Company Total at Fair Securities available for sale (Amounts In Thousands) U.S. Treasury $ 394,540 $ — $ — $ 394,540 State and political subdivisions — 285,091 — 285,091 Mortgage-backed securities and collateralized mortgage obligations — 71,216 — 71,216 Other securities (FHLB, FHLMC and FNMA) — 33,183 — 33,183 Total $ 394,540 $ 389,490 $ — $ 784,030 December 31, 2023 Readily Observable Company Total at Fair Securities available for sale (Amounts In Thousands) U.S. Treasury $ 422,490 $ — $ — $ 422,490 State and political subdivisions — 262,953 — 262,953 Mortgage-backed securities and collateralized mortgage obligations — 60,929 — 60,929 Other securities (FHLB, FHLMC and FNMA) — 33,049 — 33,049 Total $ 422,490 $ 356,931 $ — $ 779,421 (1) Considered Level 1 under ASC 820.

There were no transfers between Levels 1, 2 or 3 during the three months ended March 31, 2024 and the year ended December 31, 2023. Assets and Liabilities Recorded at Fair Value on a Nonrecurring Basis The Company is required to measure certain assets at fair value on a nonrecurring basis in accordance with GAAP. These adjustments to fair value usually result from application of lower-of-cost-or-market accounting or write-downs of individual assets. The valuation methodologies used to measure these fair value adjustments are described above.

Equity [Abstract]
Stock Repurchase Program	Stock Repurchase Program On July 26, 2005, the Company’s Board of Directors authorized a program to repurchase up to a total of 1,500,000 shares of the Company’s common stock (the “2005 Stock Repurchase Program”). On August 9, 2022, the Company’s Board of Directors authorized the expansion of the 2005 Stock Repurchase Program to allow an additional 750,000 shares for repurchase and the continuation through December 31, 2027. The Company expects the purchases pursuant to the 2005 Stock Repurchase Program to be made from time to time in private transactions at a price equal to the most recent quarterly independent appraisal of the shares of the Company’s common stock and with the Board reviewing the overall results of the 2005 Stock Repurchase Program on a quarterly basis. All purchases made pursuant to the 2005 Stock Repurchase Program since its inception have been made on that basis. The amount and timing of stock repurchases will be based on various factors, such as the Board’s assessment of the Company’s capital structure and liquidity, the amount of interest shown by shareholders in selling shares of stock to the Company at their appraised value, and applicable regulatory, legal and accounting factors. The Company has purchased 1,675,483 shares of its common stock in privately negotiated transactions from August 1, 2005 through March 31, 2024. Of these 1,675,483 shares, 47,152 shares were purchased during the quarter ended March 31, 2024, at an average price per share of $66.96.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Concentrations of credit risk : The Company’s loans, commitments to extend credit, unused lines of credit and outstanding letters of credit have been granted to customers within the Company's market area. Investments in securities issued by state and political subdivisions within the state of Iowa totaled approximately $122.26 million. The concentrations of credit by type of loan are set forth in Note 5 to the Consolidated Financial Statements. Outstanding letters of credit were granted primarily to commercial borrowers. Although the Company has a diversified loan portfolio, a substantial portion of its debtors' ability to honor their contracts is dependent upon the economic conditions in Johnson, Linn and Washington Counties, Iowa. Contingencies : In the normal course of business, the Company and its subsidiaries are subject to pending and threatened legal actions, some of which seek substantial relief or damages. While the ultimate outcome of such legal proceedings cannot be predicted with certainty, after reviewing pending and threatened litigation with counsel, management believes at this time that the outcome of such litigation will not have a material adverse effect on the Company’s business, financial conditions, or results of operations. Financial instruments with off-balance sheet risk : The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, credit card participations and standby letters of credit. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheets. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit, credit card participations and standby letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. A summary of the Company’s commitments at March 31, 2024 and December 31, 2023 is as follows: March 31, 2024 December 31, 2023 (Amounts In Thousands) Firm loan commitments and unused portion of lines of credit: Home equity loans $ 84,090 $ 84,939 Credit cards 74,851 73,677 Commercial, real estate and home construction 182,053 245,208 Commercial lines and real estate purchase loans 268,219 282,037 Outstanding letters of credit 8,976 7,654

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments In the normal course of business, the Bank may use derivative financial instruments to manage its interest rate risk. These instruments carry varying degrees of credit, interest rate and market or liquidity risks. Derivative instruments are recognized as either assets or liabilities in the accompanying consolidated financial statements and are measured at fair value. The Bank’s objectives are to add stability to its net interest margin and to manage its exposure to movements in interest rates. The contract or notional amount of a derivative is used to determine, along with the other terms of the derivative, the amount to be exchanged between the counterparties. The Bank is exposed to credit risk in the event of nonperformance by counterparties to financial instruments. The Bank minimizes this risk by entering into derivative contracts with large, stable financial institutions. The Bank has not experienced any losses from nonperformance by counterparties. The Bank monitors counterparty risk in accordance with the provisions of ASC 815. In addition, the Bank’s interest rate-related derivative instruments contain language outlining collateral pledging requirements for each counterparty. Collateral must be posted when the market value exceeds certain threshold limits which are determined by credit ratings of each counterparty. The Bank entered into one interest rate swap agreement in November 2023 and was required to pledge a US Treasury in the amount of approximately $250 thousand of collateral as of March 31, 2024. Cash Flow Hedges: The Bank executed one forward-starting interest rate swap transaction on November 28, 2023. The interest rate swap transaction had an effective date of December 15, 2023, and an expiration date of May 15, 2025, effectively converting variable rate debt to fixed rate debt. For accounting purposes, this swap transaction was designated as a cash flow hedge of the changes in cash flows attributable to changes in the effective federal funds rate, the benchmark interest rate being hedged, associated with the interest payments made on an amount of the Bank’s debt principal equal to the then-outstanding swap notional amount. The underlying principal balance will be matched to future planned advances related to a large customer construction project, however, the FHLB advances will remain equal to the notional amount of the swap making it probable that sufficient effective federal funds rate based interest payments would exist through the maturity date of the swap. The table below identifies the balance sheet category and fair value of the Bank’s derivative instrument designated as a cash flow hedge as of March 31, 2024 and December 31, 2023: Notional Fair Balance Maturity (Amounts in Thousands) March 31, 2024 Interest rate swap $ 11,500 $ 34 Other Liabilities 5/15/2025 December 31, 2023 Interest rate swap $ 2,100 $ (233) Other Liabilities 5/15/2025 The table below identifies the gains and losses recognized on the Bank’s derivative instrument designated as cash flow hedges for the three months ended March 31, 2024 and year ended December 31, 2023: Recognized in Other Comprehensive Income (Loss) Reclassified from AOCI into Income Recognized in Income on Derivatives Amount of Gain (Loss) Category Amount of Gain (Loss) Category Amount of Gain (Loss) (Amounts in Thousands) March 31, 2024 Interest rate swap $ 202 Interest Expense $ — Other Income $ — December 31, 2023 Interest rate swap $ (177) Interest Expense $ — Other Income $ —

Summary of Significant Accounting Policies (Policies)	3 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial reporting and with instructions for Form 10-Q and Regulation S-X. These financial statements include all adjustments (consisting of normal recurring accruals) which in the opinion of management are considered necessary for the fair presentation of the financial position and results of operations for the periods shown. The Company considers that it operates as one business segment, a commercial bank.
Revenue Recognition	Revenue Recognition: Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers ("ASC 606"), establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the Company’s contracts to provide goods or services to customers. The core principle requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those goods or services recognized as performance obligations are satisfied. The majority of the Company’s revenue-generating transactions are not subject to ASC 606, including revenue generated from financial instruments, such as loans, letters of credit and investment securities. Interest income on loans and investment securities is recognized on the accrual method in accordance with written contracts. Descriptions of the Company’s revenue-generating activities that are within the scope of ASC 606 are the following: Service charges and fees on deposit accounts represent general service fees for monthly account maintenance and activity- or transaction-based fees and consist of transaction-based revenue which includes interchange income, time-based revenue (service period), item-based revenue or some other individual attribute-based revenue. Revenue is recognized when the Company’s performance obligation is completed which is generally monthly for account maintenance services or when a transaction has been completed (such as a wire transfer). Payment for such performance obligations are generally received at the time the performance obligations are satisfied. Trust income represents monthly fees due from wealth management customers as consideration for managing the customers' assets. Wealth management and trust services include custody of assets, investment management, fees for trust services and similar fiduciary activities. Revenue is recognized when our performance obligation is completed each month, which is generally the time that payment is received. A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration (resulting in a contract receivable) or before payment is due (resulting in a contract asset). A contract liability balance is an entity's obligation to transfer a service to a customer for which the entity has already received payment (or payment is due) from the customer. As of March 31, 2024 and December 31, 2023, the Company did not have any significant contract balances.
Effect of New Financial Accounting Standards	Effect of New Financial Accounting Standards: In March 2022, the FASB issued ASU 2022-02, Financial Instruments - Credit Losses (Topic 326) Troubled Debt Restructurings and Vintage Disclosures . The FASB issued these amendments to eliminate accounting guidance for 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 to require that an entity disclose current-period gross writeoffs 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 amendments in this Update are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, and should be applied prospectively, except as provided in the next sentence. For the transition method related to the recognition and measurement of TDRs, an entity has the option to apply a modified retrospective transition method, resulting in a cumulative-effect adjustment to retained earnings in the period of adoption. Early adoption is permitted if an entity has adopted the amendments in Update 2016-03, including adoption in an interim period. The adoption of the ASU on a prospective basis by the Company on January 1, 2023 did not have a material impact on the financial statements, however it resulted in new disclosures. In March 2023, the FASB issued ASU 2023-02, Investments - Equity Method and Joint Ventures (Topic 323) Accounting for Investments in Tax Credit Structures Using Proportional Amortization Method . The FASB is issuing this ASU to allow reporting entities to consistently account for equity investments made primarily for the purposes of receiving income tax credits and other income tax benefits. The ASU permits reporting entities to elect to account for tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted for all entities in any interim period. If an entity adopts the amendments in an interim period, it shall adopt them as of the beginning of the fiscal year that includes that interim period. The adoption of the ASU on a prospective basis by the Company on January 1, 2024 did not have a material impact on the financial statements. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) Improvements to Reportable Segment Disclosures . The FASB is issuing this ASU to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. A public entity should apply the amendments in this Update retrospectively to all prior periods presented in the financial statements. Upon transition, the segment expense categories and amounts disclosed in the prior periods should be based on the significant segment expense categories identified and disclosed in the period of adoption. The Company is in the process of evaluating the impact of this ASU on the financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) Improvements to Income Tax Disclosures . The FASB is issuing this ASU to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this ASU require that public business entities on an annual basis disclose specific categories in the rate reconciliation, provide additional information for reconciling items that meet a quantitative threshold, disclose the amount of income taxes paid disaggregated by federal, state and foreign taxes and other disclosures. For public business entities, the amendments are effective for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The amendments in this ASU should be applied on a prospective basis. The Company is in the process of evaluating the impact of this ASU on the financial statements. In March 2024, the FASB issued ASU 2024-01, Compensation - Stock Compensation (Topic 718) Scope Application of Profits Interest and Similar Awards . The FASB is issuing this ASU to improve generally accepted accounting principles by adding an illustrative example to demonstrate how an entity should apply the scope guidance to determine whether profits interest and similar awards ("profit interest awards") should be accounted for in accordance with Topic 718, Compensation - Stock Compensation. The illustrative example is intended to reduce 1) complexity in determining whether a profits interest award is subject to the guidance in Topic 718 and 2) existing diversity in practice. For public business entities, the amendments are effective for annual periods beginning after December 15, 2024, and interim periods within those annual periods. Early adoption is permitted for both interim and annual financial statements that have not yet been issued or made available for issuance. The amendments in this Update should be applied either (1) retrospectively to all prior periods presented in the financial statements or (2) prospectively to profits interest and similar awards granted or modified on or after the date at which the entity first applies the amendments. The Company is in the process of evaluating the impact of this ASU on the financial statements.
