Nature of Operations - Heartland Financial USA, Inc. ("HTLF") is a bank holding company with locations in Iowa, Illinois, Wisconsin, New Mexico, Arizona, Colorado, Montana, Minnesota, Kansas, Missouri, Texas and California. The principal services of HTLF, which are provided through HTLF Bank, are FDIC-insured deposit accounts and related services, and loans to businesses and consumers. The loans consist primarily of commercial and industrial, owner-occupied commercial real estate, non-owner occupied commercial real estate, real estate construction, agricultural and agricultural real estate, residential real estate and consumer loans.

Principles of Presentation - The consolidated financial statements include the accounts of HTLF and its subsidiaries: HTLF Bank; DB&T Community Development Corp.; Heartland Community Development, Inc.; Heartland Financial USA, Inc. Insurance Services; Heartland Financial Statutory Trust IV; Heartland Financial Statutory Trust V; Heartland Financial Statutory Trust VI; Heartland Financial Statutory Trust VII; Morrill Statutory Trust I; Morrill Statutory Trust II; Sheboygan Statutory Trust I, CBNM Capital Trust I, Citywide Capital Trust III, Citywide Capital Trust IV, Citywide Capital Trust V, OCGI Statutory Trust III, OCGI Capital Trust IV, BVBC Capital Trust II, and BVBC Capital Trust III. All HTLF’s subsidiaries are wholly-owned as of December 31, 2023.

In the second quarter of 2023, HTLF amended and restated its Certificate of Incorporation and filed Certificates of Elimination with the state of Delaware with respect to Series A, B, C, and D preferred stock issuances, which returned these previously designated shares to authorized but unissued. The following shows the details of Series A, B, C and D preferred stock at December 31, 2022:

The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") and prevailing practices within the banking industry. In preparing such financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the balance sheets and revenues and expenses for the years then ended. Actual results could differ significantly from those estimates. A material estimate that is particularly susceptible to significant change relates to the determination of the allowance for credit losses.

Business Combinations - HTLF applies the acquisition method of accounting in accordance with the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 805, Business Combinations. Under the acquisition method, HTLF recognizes assets acquired, including identified intangible assets, and the liabilities assumed in acquisitions at fair value as of the acquisition date, with the acquisition-related transaction costs expensed in the period incurred. Determining the fair value of assets acquired and liabilities assumed often involves estimates based on third-party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques that may include estimates of attrition, inflation, asset growth rates, discount rates, multiples of earnings or other relevant factors. In addition, the determination of the useful lives over which an intangible asset will be amortized is subjective.

Cash and Cash Equivalents - For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, interest bearing deposits held at the Federal Reserve Bank, federal funds sold to other banks and other short-term investments. Generally, federal funds are purchased and sold for one-day periods.

Available for Sale ("AFS") Debt Securities and Equity Securities - Available for sale securities consist of those securities not classified as held to maturity or trading, which management intends to hold for indefinite periods of time or that may be sold in response to changes in interest rates, prepayments or other similar factors. Available for sale securities are stated at fair value with any unrealized gain or loss, net of applicable income tax, reported as a separate component of stockholders’ equity. Security premiums and discounts are amortized/accreted using the interest method over the period from the purchase date to the expected maturity or call date of the related security.

HTLF reviews the investment securities portfolio at the security level on a quarterly basis for potential credit losses, which takes into consideration numerous factors, and the relative significance of any single factor can vary by security. Some factors HTLF may consider include changes in security ratings, the financial condition of the issuer, as well as security and industry-specific economic conditions. In addition, regarding debt securities, HTLF may also evaluate payment structure, whether there are defaulted payments or expected defaults, prepayment speeds and the value of any underlying collateral. For certain debt securities in unrealized loss positions, HTLF prepares cash flow analyses to compare the present value of cash flows expected to be collected from the security with the amortized cost basis of the security.

Equity securities include Community Reinvestment Act funds with readily determinable fair values and are carried at fair value. Certain equity securities do not have readily determinable fair values, such as Federal Reserve Bank stock and Federal Home Loan Bank stock, which are held for debt and regulatory purposes and are carried at cost minus impairment, if any, plus or minus changes resulting from observable price changes for the identical or similar investment of the same issuer. HTLF did not record any impairment or other adjustments to the carrying amount of these investments during the years ended December 31, 2023, and December 31, 2022.

Allowance for Credit Losses on AFS Debt Securities - HTLF reviews the investment securities portfolio at the security level on a quarterly basis for potential credit losses, which takes into consideration numerous factors, and the relative significance of any single factor can vary by security. Some factors HTLF may consider include changes in security ratings, financial condition of the issuer, as well as security and industry-specific economic conditions. In addition, with regard to debt securities, HTLF may also evaluate payment structure, whether there are defaulted payments or expected defaults, prepayment speeds and the

The decline in fair value of an AFS debt security 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. Although these evaluations involve judgment, an unrealized loss in the fair value of a debt security is generally considered to not be related to credit when the fair value of the security is below the carrying value primarily due to changes in risk-free interest rates, there has not been significant deterioration in the financial condition of the issuer, and HTLF does not intend to sell nor does it believe it will be required to sell the security before the recovery of its cost basis. HTLF had no allowance for credit losses on AFS debt securities recorded at December 31, 2023, and December 31, 2022.

Securities Held to Maturity - Securities which HTLF has the ability and positive intent to hold to maturity are classified as held to maturity. Such securities are stated at amortized cost, adjusted for premiums and discounts that are amortized/accreted using the interest method over the period from the purchase date to the expected maturity or call date of the related security.

Allowance for Credit Losses on Held to Maturity Debt Securities - HTLF measures expected credit losses on held to maturity debt securities on a collective basis based on security type. The estimate of expected credit losses considers historical credit information that is adjusted for current conditions and supportable forecasts. HTLF's held to maturity debt securities consist primarily of investment grade obligations of states and political subdivisions. The forecast and forecast period used in the calculation of the allowance for credit losses for loans is used in calculating the allowance for credit losses on held to maturity debt securities. HTLF had no allowance for credit losses on held to maturity debt securities recorded at both December 31, 2023, and December 31, 2022.

Loans Held to Maturity - Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost, which is the principal amount outstanding, net of cumulative charge-offs, unamortized net deferred loan origination fees and costs and unamortized premiums or discounts on purchased loans. HTLF has a loan policy which establishes the credit risk appetite, lending standards and underwriting criteria designed so that HTLF may extend credit in a prudent and sound manner. The HTLF loan policy is reviewed and approved on a regular basis. A reporting system supplements the review process by providing management and the board with frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies and nonperforming loans and potential problem loans.

HTLF originates commercial and industrial loans and owner occupied commercial real estate loans for a wide variety of business purposes, including lines of credit for capital and operating purposes and term loans for real estate and equipment purchases. Non-owner occupied commercial real estate loans provide financing for various non-owner occupied or income producing properties. Real estate construction loans are generally short-term or interim loans that provide financing for acquiring or developing commercial income properties, multi-family projects or single-family residential homes. Agricultural and agricultural real estate loans provide financing for capital improvements and farm operations, as well as livestock and machinery purchases. Residential real estate loans are originated for the purchase or refinancing of single-family residential properties. Consumer loans include loans for motor vehicles, home improvement, home equity and personal lines of credit.

Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. HTLF’s policy is to discontinue the accrual of interest income on any loan when, in the opinion of management, there is a reasonable doubt as to the timely collection of the interest and principal, normally when a loan is 90 days past due. When interest accruals are deemed uncollectible, interest credited to income in the current year is reversed and interest accrued in prior years is charged to the allowance for credit losses. A loan can be restored to accrual status if the borrower has resumed paying the full amount of the scheduled contractual interest and principal payments on the loan, and (1) all principal and interest amounts contractually due (including arrearages) are reasonably assured of repayment within a reasonable period of time, and (2) there is a sustained period of repayment performance (generally a minimum of six months) by the borrower in accordance with the scheduled contractual terms.

Allowance for Credit Losses for Loans - The allowance for credit losses is a valuation account that is deducted from the loans held to maturity amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged-off against the allowance when management believes the loan balance is deemed to be uncollectible. Provisions for credit losses for loans and recoveries on loans previously charged-off by HTLF are added back to the allowance.

Management's estimation of expected credit losses is based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts, including expected defaults and prepayments. Historical loss experience is generally the starting point for estimating expected credit losses. Adjustments are made to historical loss experience to reflect differences in asset-specific risk characteristics, such as underwriting standards, portfolio mix or asset terms and differences in economic conditions, both current conditions and reasonable and supportable forecasts. If HTLF is not able to make or obtain reasonable and supportable forecasts for the entire life of the financial asset, it is required to estimate expected credit losses for the remaining life using an approach that reverts to historical credit loss information. The components of the allowance for credit losses are described more specifically below.

The quantitative component of the allowance for credit losses is measured using historical loss experience using a look back period, currently over the most recent 16 years, on a pool basis for loans with similar risk characteristics. HTLF utilizes third-party software to calculate the expected credit losses using two separate methodologies. For certain commercial and agricultural loans, the expected credit losses are calculated through a transition matrix model derived probability of default and loss given default methodology. The transition matrix model determines the life of loan probability of default using the historical transitions of loans between risk ratings and through default. The probability of default and loss given default methodology has been developed using HTLF’s historical loss experience over the look back period. For smaller commercial and agricultural loans, residential real estate loans and consumer loans, a lifetime average historical loss rate is established for each pool of loans based upon an average loss rate calculated using HTLF historical loss experience over the look back period.

The risks in the commercial and industrial loan portfolio include the unpredictability of the cash flow of the borrowers and the variability in the value of the collateral securing the loans. Owner occupied commercial real estate loans depend upon the cash flow of the borrowers and the collateral value of the real estate. Non-owner occupied commercial real estate loans typically depend, in large part, on sufficient income from the properties securing the loans to cover the operating expenses and debt service. Real estate construction loans involve additional risks because funds are advanced based upon estimates of costs and the estimated value of the completed project. Additionally, real estate construction loans have a greater risk of default in a weaker economy because the source of repayment relies on the successful and timely completion of the project. Agricultural and agricultural real estate loans depend upon the profitable operation or management of the farm property securing the loan. Loans secured by farm equipment, livestock or crops may not provide an adequate source of repayment because of damage or depreciation. Residential real estate loans depend upon the borrower's ability to repay the loan and the underlying collateral value. Consumer loans depend upon the borrower's personal financial circumstances and continued financial stability.

If a loan no longer shares similar risk characteristics with other loans in the pool, it is evaluated on an individual basis and is not included in the collective evaluation. Lending relationships with $500,000 or more of total exposure and on nonaccrual status are individually assessed using a collateral dependency calculation. A loan is collateral-dependent when the debtor is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operation of the collateral. The impairment will be recognized by creating a specific reserve against the loan with a corresponding charge to provision expense. In most cases, the specific reserve will be charged off in the same quarter the loss is probable. In some cases, when HTLF believes certain loans do not share the same risk characteristics with other loans in the pool, the standard allows for these loans to be individually assessed. All individually assessed loan calculations are completed at least semi-annually.

HTLF's allowance methodology also has a qualitative component, the purpose of which is to provide management with a means to take into consideration changes in current conditions that could potentially have an effect on the level of recognized loan losses, that otherwise fail to show up in the quantitative analysis performed in determining its base loan loss rates.

The qualitative adjustments are based on the comparison of the current condition to the average condition over the look back period. The adjustment amount can be either positive or negative depending on whether the current condition is better or worse than the historical average. HTLF incorporates the adjustments for changes in current conditions using an overlay approach. The adjustments are applied as a percentage adjustment in addition to the calculated historical loss rates of each pool. These adjustments reflect the extent to which HTLF expects current conditions to differ from the conditions that existed for the period over which historical information was evaluated. HTLF utilizes an anchoring approach to determine the minimum and maximum amount of qualitative allowance for credit losses, which is determined by comparing the highest and lowest historical rate to the current quantitative allowance rate to calculate the rate for the adjustment.

The allowance for credit losses estimate incorporates a reasonable and supportable forecast of various macro-economic indices over the remaining life of HTLF’s assets. HTLF utilizes an overlay approach for its economic forecasting component, similar to the method utilized for the qualitative factors. The length of the reasonable and supportable forecast period is a judgmental determination based on the level to which the entity can support its forecast of economic conditions that drive its estimate of expected loss. HTLF compares forecasted macro-economic indices, such as unemployment and gross domestic product, to the economic conditions that existed over HTLF's look back period.

HTLF uses Moody's baseline economic forecast scenario, which is updated quarterly in HTLF's methodology, and considers other Moody's forecast scenarios to support the economic forecast component of the allowance for credit losses. The economic forecast reverts to the historical mean immediately at the end of the reasonable and supportable forecast period. HTLF utilized a one-year reasonable and supportable forecast period for the calculation of the December 31, 2023, and December 31, 2022, allowance for credit losses.

It is expected that actual economic conditions will, in many cases, differ from forecasts because the ultimate outcomes during the forecast period may be affected by events that were unforeseen, such as economic disruption and fiscal or monetary policy actions, which are exacerbated by longer forecasting periods. This uncertainty would be relevant to the entity’s confidence level as to the outcomes being forecasted. That is, an entity is likely less confident in the ultimate outcome of events that will occur at the end of the forecast period as compared to the beginning. As a result, actual future economic conditions may not be an effective indicator of the quality of management’s forecasting process, including the length of the forecast period.

Financial Difficulty Modifications - Any loans that are modified are reviewed by HTLF to identify if a financial difficulty modification has occurred, which is when HTLF modifies a loan related to a borrower experiencing financial difficulties. Terms may be modified to fit the ability of the borrower to repay in line with its current financial status. The modification of the terms of such loans includes one or a combination of the following: a reduction of the stated interest rate of the loan, an extension of the maturity date, a permanent reduction of the recorded investment of the loan, or an other-than-insignificant payment delay. The adoption of ASU 2022-02 on January 1, 2023 eliminated the recognition and measurement of TDRs and enhanced disclosures for modifications to loans related to borrowers experiencing financial difficulties. See Note Four to the consolidated financial statements for additional detail regarding the adoption of ASU 2022-02.

Loans Held for Sale - Loans held for sale are stated at the lower of cost or fair value on an aggregate basis. Gains or losses on sales are recorded in noninterest income. Direct loan origination costs and fees are deferred at origination of the loan. These deferred costs and fees are recognized in noninterest income as part of the gain or loss on sales of loans upon sale of the loan.

Allowance for Credit Losses on Unfunded Loan Commitments - HTLF estimates expected credit losses over the contractual term of the loan for the unfunded portion of the loan commitment that is not unconditionally cancellable by HTLF using the same collective allowance methodology for credit losses for loans described above. Management uses an estimated average utilization rate to determine the exposure at default. The allowance for unfunded commitments is recorded in the Accrued Expenses and Other Liabilities section of the consolidated balance sheets.

Mortgage Servicing and Transfers of Financial Assets - Prior to dissolving its mortgage operations in 2023, HTLF regularly sold residential mortgage loans to others, primarily government sponsored entities, on a non-recourse basis. Sold loans are not included in the accompanying consolidated balance sheets. HTLF generally retained the right to service the sold loans for a fee prior to the sale of its mortgage servicing rights portfolio in the first quarter of 2023. First Bank & Trust, a division of HTLF Bank, serviced mortgage loans primarily for government sponsored entities with aggregate unpaid principal balance of $0 and $725.9 million, at December 31, 2023 and 2022, respectively.

Premises, Furniture and Equipment, net - Premises, furniture and equipment are stated at cost less accumulated depreciation. The provision for depreciation of premises, furniture and equipment is determined by straight-line and accelerated methods over the estimated useful lives of 18 to 39 years for buildings, 15 years for land improvements and 3 to 7 years for furniture and equipment.

Other Real Estate - Other real estate represents property acquired through foreclosures and settlements of loans. Property acquired is recorded at the estimated fair value of the property less disposal costs. The excess of carrying value over fair value less disposal costs is charged against the allowance for credit losses. Subsequent write downs estimated on the basis of later valuations and gains or losses on sales are charged to gain (loss) on sales/valuation of assets, net. Expenses incurred in maintaining such properties are charged to other real estate and loan collection expenses.

Goodwill - Goodwill represents the excess of the purchase price of acquired subsidiaries’ net assets over their fair value at the purchase date. HTLF assesses goodwill for impairment annually, and more frequently if events occur which may indicate possible impairment, and assesses goodwill at the reporting unit level, also giving consideration to overall enterprise value as part of that assessment.

In evaluating goodwill for impairment, HTLF first assesses qualitative factors to determine whether it is more likely than not (that is, a likelihood of more than 50%) that the fair value of a reporting unit is less than its carrying amount. If HTLF concludes that it is more likely than not that the fair value of a reporting unit is more than its carrying value, then no further testing of goodwill assigned to the reporting unit is required. However, if HTLF concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying value, then HTLF performs a quantitative goodwill impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment to recognize, if any. In addition, the income tax effects of tax-deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. A goodwill impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized cannot exceed the total amount of goodwill allocated to that reporting unit.

Core Deposit Intangibles and Customer Relationship Intangibles, Net - Core deposit intangibles are amortized over 8 to 18 years on an accelerated basis. Customer relationship intangibles were amortized over 22 years on an accelerated basis. Annually, HTLF reviews these intangible assets for events or circumstances that may indicate a change in the recoverability of the underlying basis.

Servicing Rights, Net - Mortgage and commercial servicing rights associated with loans originated and sold, where servicing is retained, are initially capitalized at fair value and recorded on the consolidated statements of income as a component of gains on sale of loans held for sale. The values of these capitalized servicing rights are amortized as an offset to the loan servicing income earned in relation to the servicing revenue expected to be earned.

First Bank & Trust, a division of HTLF Bank, sold its mortgage servicing portfolio in the first quarter of 2023, and the value of the mortgage servicing rights was derecognized on the consolidated balance sheet. In prior periods, the carrying values of these rights were reviewed quarterly for impairment based on the calculation of their fair value as performed by an outside third-party. For purposes of measuring impairment, the rights were stratified into certain risk characteristics including loan type and loan term. At December 31, 2022, no valuation allowance was required on HTLF's mortgage servicing rights with an original term of 15 years, and no valuation allowance was required on HTLF's mortgage servicing rights with an original term of 30 years.

Cash Surrender Value on Life Insurance - HTLF and its subsidiaries have purchased life insurance policies on the lives of certain officers. The one-time premiums paid for the policies, which coincide with the initial cash surrender value, are recorded as an asset. Increases or decreases in the cash surrender value, other than proceeds from death benefits, are recorded as noninterest income in income on bank owned life insurance. Proceeds from death benefits first reduce the cash surrender value attributable to the individual policy and then any additional proceeds are recorded in other noninterest income.

Income Taxes - HTLF and its subsidiaries file a consolidated federal income tax return and separate or combined income or franchise tax returns as required by the various states. HTLF recognizes certain income and expenses in different time periods for financial reporting and income tax purposes. The provision for deferred income taxes is based on an asset and liability

A tax position is recognized as a benefit only if it is "more likely than not" that the tax position would be sustained in a tax examination. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. HTLF recognizes interest and penalties related to income tax matters in income tax expense.

Derivative Financial Instruments - HTLF uses derivative financial instruments as part of its interest rate risk management, which includes interest rate swaps, certain interest rate lock commitments and forward sales of securities related to mortgage banking activities. FASB ASC Topic 815 establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. As required by ASC 815, HTLF records all derivatives on the consolidated balance sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives used to manage the exposure to changes in the fair value of a recognized asset or liability on the consolidated balance sheets are fair value hedges. To qualify for hedge accounting, HTLF must comply with the detailed rules and documentation requirements at the inception of the hedge, and hedge effectiveness is assessed at inception and periodically throughout the life of each hedging relationship. Hedge ineffectiveness, if any, is measured periodically throughout the life of the hedging relationship.

For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in other comprehensive income (loss) and subsequently reclassified to interest income or expense when the hedged transaction affects earnings, while the ineffective portion of changes in the fair value of the derivative, if any, is recognized immediately in other noninterest income. HTLF assesses the effectiveness of each hedging relationship by comparing the cumulative changes in cash flows of the derivative hedging instrument with the cumulative changes in cash flows of the designated hedged item or transaction. No component of the change in the fair value of the hedging instrument is excluded from the assessment of hedge effectiveness. In the first quarter of 2023 HTLF terminated its cash flow hedges. It was determined that the forecasted transactions remain probable, so the unrealized gains at termination were kept in accumulated comprehensive income and are being amortized into income over the remaining life of the forecasted transaction.

HTLF had multiple fair value hedging relationships at December 31, 2023. HTLF uses hedge accounting in accordance with ASC 815. For hedges where the fair value change in the loan portfolio is being hedged, unrealized gains and losses representing the change in fair value of the derivative and the change in fair value of the risk being hedged on the related loan are being recorded in the consolidated statements of income. The ineffective portions of the unrealized gains or losses, if any, are recorded in interest income in the consolidated statements of income. For hedges where the fair value change in the investment portfolio are being hedged, the change in the fair value of the derivative and the change in the fair value of the risk being hedged on the related investments is being recorded in interest income on the consolidated statements of income. The ineffective portions of the unrealized gains or losses, if any, are recorded in interest income in the consolidated statements of income. HTLF uses statistical regression to assess hedge effectiveness, both at the inception of the hedge as well as on a continual basis. The regression analysis involves regressing the periodic change in fair value of the hedging instrument against the periodic changes in the fair value of the asset being hedged due to changes in the hedge risk.

HTLF also has loan interest rate swap relationships with customers to assist them in managing their interest rate risk. Upon entering into these loan swaps HTLF enters into offsetting positions with counterparties in order to minimize interest rate risk to HTLF. These back-to-back loan swaps qualify as free standing financial derivatives with the fair values reported in other assets and other liabilities on the consolidated balance sheets. Any gains and losses on these back-to-back swaps are recorded in noninterest income on the consolidated statements of income.

Mortgage Derivatives - HTLF uses interest rate lock commitments to originate residential mortgage loans held for sale and forward commitments to sell residential mortgage loans and mortgage-backed securities. These commitments are considered derivative instruments. The fair value of these commitments is recorded on the consolidated balance sheets with the changes in fair value recorded in the consolidated statements of income as a component of gains on sale of loans held for sale. These derivative contracts are designated as free-standing derivative contracts and are not designated against specific assets and liabilities on the consolidated balance sheets or forecasted transactions and therefore do not qualify for hedge accounting treatment. As of December 31, 2023, HTLF was winding out of this activity due to dissolving its mortgage operations.

Fair Value Measurements - Fair value represents the estimated price at which an orderly transaction to sell an asset or transfer a liability would take place between market participants at the measurement date under current market conditions (i.e., an exit price concept). Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using discounted cash flow or other valuation techniques. Inputs into the valuation methods are subjective in nature, involve uncertainties, and require judgment and therefore cannot be determined with precision. Accordingly, the derived fair value estimates presented herein are not necessarily indicative of the amounts HTLF could realize in a current market exchange. Assets and liabilities are categorized into three levels based on the markets in which the assets and liabilities are traded, and the reliability of the assumptions used to determine the fair value. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy in which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. HTLF's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Below is a brief description of each fair value level:

Level 3 — Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques.

Segment Reporting - Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker ("CODM"), which is the Chief Executive Officer of HTLF, in deciding how to allocate resources and assess the financial and operating performance of HTLF. HTLF’s operating segments provide, and primarily derive revenue, through full service commercial and consumer banking. HTLF has determined that the economic characteristics, operating models, performance metrics, suite of products and services, customer base, and regulatory requirements are similar for its operating segments and has therefore aggregated them into one reportable segment.

Treasury Stock - Treasury stock is accounted for by the cost method, whereby shares of common stock reacquired are recorded at their purchase price. When treasury stock is reissued, any difference between the sales proceeds, or fair value when issued for business combinations, and the cost is recognized as a charge or credit to capital surplus. HTLF had no treasury stock at December 31, 2023 and December 31, 2022.

Earnings Per Share - Basic earnings per share is determined using net income available to common stockholders and weighted average common shares outstanding. Diluted earnings per share is computed by dividing net income available to common stockholders by the weighted average common shares and assumed incremental common shares issued. Amounts used in the determination of basic and diluted earnings per share for the years ended December 31, 2023, 2022 and 2021, are shown in the table below, dollars and number of shares in thousands, except per share data:


	2023		2022		2021

Subsequent to December 31, 2023, in February of 2024, HTLF announced that HTLF Bank had signed definitive agreements to sell its nine Rocky Mountain Bank division branches to two purchasers. The agreements include the sale of approximately $588.9 million of deposits, $365.9 million of loans and $13.6 million of premises, furniture and equipment. The transaction is expected to close in the latter half of 2024.

In March 2022, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2022-01, "Derivatives and Hedging (Topic 815): Fair Value Hedging-Portfolio Layer Method," which expands the current last-of-layer method by allowing multiple hedged layers to be designated for a single closed portfolio of financial assets or one or more beneficial interests secured by a portfolio of financial instruments. HTLF adopted this ASU on January 1, 2023, and these amendments were applied prospectively.

In March 2022, the FASB issued ASU 2022-02, "Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures." These amendments eliminate the troubled debt restructurings ("TDR") recognition and measurement guidance and, instead, require that an entity evaluate (consistent with the accounting for other loan modifications) whether the modification represents a new loan or a continuation of an existing loan. The amendments also enhance existing disclosure requirements and introduce new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. Additionally, these amendments require that an entity disclose current-period gross charge-offs by year of origination for loans receivable within the scope of Subtopic 326-20. The guidance is effective for entities that have adopted ASU 2016-13 for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. These amendments should be applied prospectively. If an entity elects to early adopt ASU 2022-02 in an interim period, the guidance should be applied as of the beginning of the fiscal year that includes the interim period. An entity may elect to early adopt the amendments about TDRs and related disclosure enhancements separately from the amendments related to vintage disclosures. HTLF adopted this ASU on January 1, 2023, as required, and the adoption did not have a material impact on its results of operations, financial position or liquidity.

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 the Proportional Amortization Method (a consensus of the Emerging Task Force)." ASU 2023-02 expands the permitted use of the proportional amortization method, which is currently only available to low-income housing tax credit investments, to other tax equity investments if certain conditions are met.
