Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The interim unaudited consolidated financial statements contained herein should be read in conjunction with the audited consolidated financial statements and accompanying notes to the consolidated financial statements for the fiscal year ended December 31, 2021, included in the Annual Report on Form 10-K of Heartland Financial USA, Inc. ("HTLF") filed with the Securities and Exchange Commission ("SEC") on February 24, 2022 . Foot note disclosures to the interim unaudited consolidated financial statements which would substantially duplicate the disclosure contained in the footnotes to the audited consolidated financial statements have been omitted. The financial information included herein has been prepared in accordance with U.S. generally accepted accounting principles for interim financial reporting and has been prepared pursuant to the rules and regulations for reporting on Form 10-Q and Rule 10-01 of Regulation S-X. Such information reflects all adjustments (consisting of normal recurring adjustments), that are, in the opinion of management, necessary for a fair presentation of the financial position and results of operations for the periods presented. The results of the interim period ended June 30, 2022, are not necessarily indicative of the results expected for the year ending 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 three- and six- months ended June 30, 2022, and 2021, are shown in the table below, dollars and number of shares in thousands, except per share data: Three Months Ended 2022 2021 Net income $ 51,873 $ 61,605 Preferred dividends (2,012) (2,012) Net income available to common stockholders $ 49,861 $ 59,593 Weighted average common shares outstanding for basic earnings per share 42,475 42,243 Assumed incremental common shares issued upon vesting of outstanding restricted stock units 91 117 Weighted average common shares for diluted earnings per share 42,566 42,360 Earnings per common share — basic $ 1.17 $ 1.41 Earnings per common share — diluted $ 1.17 $ 1.41 Number of antidilutive common stock equivalents excluded from diluted earnings per share computation 172 1 Six Months Ended 2022 2021 Net income $ 94,962 $ 114,419 Preferred dividends (4,025) (4,025) Net income available to stockholders $ 90,937 $ 110,394 Weighted average common shares outstanding for basic earnings per share 42,418 42,210 Assumed incremental common shares issued upon vesting of outstanding restricted stock units 145 147 Weighted average common shares for diluted earnings per share 42,563 42,357 Earnings per common share — basic $ 2.14 $ 2.62 Earnings per common share — diluted $ 2.14 $ 2.61 Number of antidilutive common stock equivalents excluded from diluted earnings per share computation 76 60 Subsequent Events - HTLF has evaluated subsequent events that may require recognition or disclosure through the filing date of this Quarterly Report on Form 10-Q with the SEC. On August 5, 2022, HTLF paid $4.5 million to settle a lawsuit related to pending litigation involving a former customer of AimBank. The aggregate amount of cash consideration paid in the AimBank transaction in December 2020 was reduced by $5.3 million as a holdback against any losses that might be incurred as a result of this pending litigation. The final amount payable to the AimBank shareholders under the holdback will be determined in accordance with the terms of the merger agreement. However, it is the opinion of management that the settlement of this legal action will not have a material effect on HTLF's consolidated position or results of operations. Effect of New Financial Accounting Standards ASU 2018-16 In October 2018, the FASB issued ASU 2018-16, " Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting." In the United States, eligible benchmark interest rates under Topic 815 are interest rates on direct Treasury obligations of the U.S. government, the London Interbank Offered Rate ("LIBOR") swap rate, and the Overnight Index Swap ("OIS") Rate based on the Fed Funds Effective Rate. When the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities , in August 2017, it introduced the Securities Industry and Financial Markets Association ("SIFMA") Municipal Swap Rate as the fourth permissible U.S. benchmark rate. ASU 2018-16 adds the OIS rate based on the Secured Overnight Financing Rate ("SOFR") as a U.S. benchmark interest rate to facilitate the LIBOR to SOFR transition and provide sufficient lead time for entities to prepare for changes to interest rate risk hedging strategies for both risk management and hedge accounting purposes. ASU 2018-16 became effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years and the financial statement impact immediately upon adoption was immaterial. The future financial statement impact will depend on any new contracts entered into using new benchmark rates, as well as any existing contracts that are migrated from LIBOR to new benchmark interest rates. HTLF has a formal working group that is responsible for the planning, assessment and execution of the transition from LIBOR as an interest rate benchmark to term SOFR. Currently, HTLF has adjustable rate loans, several debt obligations and securities and derivative instruments in place that reference LIBOR-based rates. HTLF’s transition plan included the cessation in new contracts of the use of LIBOR as a reference rate at December 31, 2021. ASU 2020-04 In March 2020, the FASB issued ASU 2020-04, " Reference Rate Reform, " which provides optional expedients and exceptions for applying GAAP to loan and lease agreements, derivative contracts, and other transactions affected by the anticipated transition away from LIBOR toward new interest rate benchmarks. For loan and lease agreements that are modified because of reference rate reform and that meet certain scope guidance (i) modifications of loan agreements should be accounted for by prospectively adjusting the effective interest rate, and the modifications would be considered "minor" with the result that any existing unamortized origination fees/costs would carry forward and continue to be amortized and (ii) modifications of lease agreements should be accounted for as a continuation of the existing agreement, with no reassessments of the lease classification and the discount rate or remeasurements of lease payments that otherwise would be required for modifications not accounted for as separate contracts. ASU 2020-04 also provides numerous optional expedients for derivative accounting. ASU 2020-04 is effective March 12, 2020 through December 31, 2022. An entity may elect to apply ASU 2020-04 for contract modifications as of January 1, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. Once elected for a Topic or an Industry Subtopic within the ASC, ASU 2020-04 must be applied prospectively for all eligible contract modifications for that Topic or Industry Subtopic. HTLF anticipates that ASU 2020-04 will simplify any modifications executed between the selected start date and December 31, 2022 that are directly related to LIBOR transition by allowing prospective recognition of the continuation of the contract, rather than extinguishment of the old contract that would result in writing off unamortized fees/costs. Management will continue to actively assess the impacts of ASU 2020-04 and the related opportunities and risks involved in the LIBOR transition. ASU 2022-02 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

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 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. The unrealized losses on HTLF's mortgage and asset-backed securities are the result of changes in market interest rates or widening of market spreads subsequent to the initial purchase of the securities. The losses are not related to concerns regarding the underlying credit of the issuers or the underlying collateral. It is expected that the securities will not be settled at a price less than the amortized cost of the investment. Because the decline in fair value is attributable to changes in interest rates or widening market spreads and not credit quality, and because HTLF has the intent and ability to hold these investments until a market price recovery or to maturity and does not believe it will be required to sell the securities before maturity, no credit losses were recognized on these securities during the three and six months ended June 30, 2022 and 2021. The unrealized losses on HTLF's obligations of states and political subdivisions are the result of changes in market interest rates or widening of market spreads subsequent to the initial purchase of the securities. Management monitors the published credit ratings of these securities and the stability of the underlying municipalities. Because the decline in fair value is attributable to changes in interest rates or widening market spreads due to insurance company downgrades and not underlying credit quality, and because HTLF has the intent and ability to hold these investments until a market price recovery or to maturity and does not believe it will be required to sell the securities before maturity, no credit losses were recognized on these securities during the three and six months ended June 30, 2022 and 2021. In the first quarter of 2022, HTLF sold two obligations of states and political subdivisions securities from the held to maturity portfolio. Because the underlying credit quality of the individual securities showed significant deterioration, it was unlikely HTLF would recover the remaining basis of the securities prior to maturity and therefore inconsistent with HTLF's original intent upon purchase and classification of these held to maturity securities. The carrying value of these securities was $2.2 million, and the associated gross gains were $100,000. The credit loss model under ASC 326-30, applicable to held to maturity debt securities, requires the recognition of lifetime expected credit losses through an allowance account at the time when the security is purchased. The following tables present, in thousands, the activity in the allowance for credit losses for securities held to maturity by obligations of states and political subdivisions securities for the three and six months ended June 30, 2022 and 2021: Three Months Ended 2022 2021 Beginning balance $ — $ 48 Provision (benefit) for credit losses — 3 Balance at period end $ — $ 51 Six Months Ended 2022 2021 Beginning balance $ — $ 51 Provision (benefit) for credit losses — — Balance at period end $ — $ 51 Based on HTLF's credit loss model applicable to held to maturity debt securities, no allowance for credit losses was required at both June 30, 2022 and December 31, 2021. The following table summarizes, in thousands, the carrying amount of HTLF's held to maturity debt securities by investment rating as of June 30, 2022 and December 31, 2021, which are updated quarterly and used to monitor the credit quality of the securities: June 30, 2022 December 31, 2021 Rating AAA $ 3,324 $ 3,265 AA, AA+, AA- 54,154 61,471 A+, A, A- 18,760 15,034 BBB 5,701 4,939 Not Rated — — Total $ 81,939 $ 84,709 Included in other securities were shares of stock in each Federal Home Loan Bank (the "FHLB") of Des Moines, Chicago, Dallas, San Francisco and Topeka at an amortized cost of $24.4 million at June 30, 2022 and $22.6 million at December 31, 2021. The HTLF banks are required by federal law to maintain FHLB stock as members of the various FHLBs. These equity securities are "restricted" in that they can only be sold back to the respective institutions from which they were acquired or another member institution at par. Therefore, the FHLB stock is less liquid than other marketable equity securities, and the fair value approximates amortized cost. HTLF considers its FHLB stock as a long-term investment that provides access to competitive products and liquidity. HTLF evaluates impairment in these investments based on the ultimate recoverability of the par value and, at June 30, 2022, and December 31, 2021, did not consider the investments to be impaired.

HTLF does not consider accrued interest receivable in the allowance for credit losses calculation. The following table shows the balance in the allowance for credit losses at June 30, 2022, and December 31, 2021, and the related loan balances, disaggregated on the basis of measurement methodology, in thousands. 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.

HTLF had $10.4 million of troubled debt restructured loans at December 31, 2021, of which $9.5 million were classified as nonaccrual and $817,000 were accruing according to the restructured terms. The following tables provide information on troubled debt restructured loans that were modified in the during the three- and six- months ended June 30, 2022, and June 30, 2021, dollars in thousands.

HTLF had no troubled debt restructured loans for which there was a payment default during the three- and six- months ended June 30, 2022, and June 30, 2021, that had been modified during the twelve-month period prior to default. HTLF's internal rating system is a series of grades reflecting management's credit risk assessment, based on its analysis of the borrower's financial condition. The "pass" category consists of all loans that are not in the "nonpass" category and categorized into a range of loan grades that reflect increasing, though still acceptable, risk. Movement of risk through the various grade levels in the pass category is monitored for early identification of credit deterioration. The "nonpass" category consists of watch, substandard, doubtful and loss rated loans. The "watch" rating is attached to loans where the borrower exhibits negative trends in financial circumstances due to borrower specific or systemic conditions that, if left uncorrected, threaten the borrower's capacity to meet its debt obligations. The borrower is believed to have sufficient financial flexibility to react to and resolve its negative financial situation. These credits are closely monitored for improvement or deterioration. The "substandard" rating is assigned to loans that are inadequately protected by the current net worth and repaying capacity of the borrower and that may be further at risk due to deterioration in the value of collateral pledged. Well-defined weaknesses jeopardize liquidation of the debt. These loans are still considered collectible; however, a distinct possibility exists that HTLF will sustain some loss if deficiencies are not corrected. Substandard loans may exhibit some or all of the following weaknesses: deteriorating financial trends, lack of earnings, inadequate debt service capacity, excessive debt and/or lack of liquidity. The "doubtful" rating is assigned to loans where identified weaknesses in the borrowers' ability to repay the loan make collection or liquidation in full, on the basis of existing facts, conditions and values, highly questionable and improbable. These borrowers are usually in default, lack liquidity and capital, as well as resources necessary to remain as an operating entity. Specific pending events, such as capital injections, liquidations or perfection of liens on additional collateral, may strengthen the credit, thus deferring the rating of the loan as "loss" until the exact status of the loan can be determined. The "loss" rating is assigned to loans considered uncollectible. HTLF had no loans classified as "loss" or "doubtful" as of June 30, 2022 and December 31, 2021.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL, CORE DEPOSIT PREMIUM AND OTHER INTANGIBLE ASSETS	GOODWILL, CORE DEPOSIT PREMIUM AND OTHER INTANGIBLE ASSETS HTLF had goodwill of $576.0 million at both June 30, 2022 and December 31, 2021. HTLF conducts its annual internal assessment of the goodwill both at the consolidated level and at its subsidiaries as of September 30. HTLF performed its annual quantitative assessment of goodwill as of September 30, 2021, which was the most recent annual assessment, and there was no goodwill impairment. At June 30, 2022, HTLF's intangible assets consisted of core deposit intangibles and mortgage servicing rights. At December 31, 2021, HTLF's intangible assets consisted of core deposit intangibles, mortgage servicing rights, customer relationship intangibles, and commercial servicing rights. The gross carrying amount of these intangible assets and the associated accumulated amortization at June 30, 2022, and December 31, 2021, are presented in the table below, in thousands: June 30, 2022 December 31, 2021 Gross Accumulated Net Gross Accumulated Net Amortizing intangible assets: Core deposit intangibles $ 101,185 $ 72,334 $ 28,851 $ 101,185 $ 68,330 $ 32,855 Customer relationship intangibles 1,177 1,177 — 1,177 1,044 133 Mortgage servicing rights 13,531 5,243 8,288 12,790 6,378 6,412 Commercial servicing rights 7,054 7,054 — 7,054 6,576 478 Total $ 122,947 $ 85,808 $ 37,139 $ 122,206 $ 82,328 $ 39,878 The following table shows the estimated future amortization expense for amortizable intangible assets, in thousands: Core Deposit Mortgage Servicing Six months ending December 31, 2022 $ 3,697 $ 562 $ 4,259 Year ending December 31, 2023 6,739 1,931 8,670 2024 5,591 1,655 7,246 2025 4,700 1,380 6,080 2026 3,533 1,104 4,637 2027 2,601 828 3,429 Thereafter 1,990 828 2,818 Total $ 28,851 $ 8,288 $ 37,139 Projections of amortization expense for mortgage servicing rights are based on existing asset balances and the existing interest rate environment as of June 30, 2022. HTLF's actual experience may be significantly different depending upon changes in mortgage interest rates and market conditions. Mortgage loans serviced for others at First Bank & Trust were approximately $736.6 million at June 30, 2022, compared to $723.3 million at December 31, 2021. Custodial escrow balances maintained in connection with the mortgage loan servicing portfolio were approximately $12.8 million at June 30, 2022, and $4.5 million at December 31, 2021. Fees collected for the servicing of mortgage loans for others were $466,000 and $459,000 for the quarters ended June 30, 2022 and June 30, 2021, respectively. Fees collected for the servicing of mortgage loans for others were $919,000 and $923,000 for the six months ended June 30, 2022 and June 30, 2021, respectively. The following table summarizes, in thousands, the changes in capitalized mortgage servicing rights for the six months ended June 30, 2022, and June 30, 2021: 2022 2021 Balance at January 1, $ 6,412 $ 5,189 Originations 904 703 Amortization (686) (724) Valuation adjustment 1,658 391 Balance at period end $ 8,288 $ 5,559 Mortgage servicing rights, net to servicing portfolio 1.13 % 0.77 % Mortgage rights are initially recorded at fair value in net gains on sale of loans held for sale when they are capitalized through loan sales. Fair value is based on market prices for comparable servicing contracts, when available, or based on a valuation model that calculates the present value of estimated future net servicing income. Mortgage rights are subsequently measured using the amortization method, which requires the asset to be amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. Servicing rights are evaluated for impairment at each HTLF subsidiary which has servicing rights based upon the fair value of the assets as compared to the carrying amount. Impairment is recognized through a valuation allowance for specific tranches to the extent that fair value is less than the carrying amount at each HTLF subsidiary which has servicing rights, and a valuation adjustment is recorded into noninterest income. At June 30, 2022, no valuation allowance was required on the mortgage servicing rights 15-year tranche, and no valuation allowance was required on the mortgage servicing rights 30-year tranche. At December 31, 2021, a $327,000 valuation allowance was required on the mortgage servicing rights 15-year tranche and a $1.3 million valuation allowance was required on the mortgage servicing rights 30-year tranche. For the three months ended June 30, 2022 and June 30, 2021, a valuation adjustment of $0 and $526,000, respectively, was recorded for the total mortgage servicing rights portfolio. For the six months ended June 30, 2022 and June 30, 2021, a valuation adjustment benefit of $1.7 million and $391,000, respectively, was recorded for the total mortgage servicing rights portfolio. The following table summarizes, in thousands, the book value, the fair value of each tranche of the mortgage servicing rights and any recorded valuation allowance at June 30, 2022, and December 31, 2021: Book Value 15-Year Tranche Fair Value 15-Year Tranche Valuation Allowance Book Value 30-Year Tranche Fair Value 30-Year Tranche Valuation Allowance June 30, 2022 $ 1,595 $ 1,838 $ — $ 6,693 $ 7,582 $ — December 31, 2021 1,607 1,280 327 6,463 5,132 1,331 The fair value of mortgage servicing rights is calculated based upon a discounted cash flow analysis.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTS HTLF uses derivative financial instruments as part of its interest rate risk management strategy. As part of the strategy, HTLF considers the use of interest rate swaps, risk participation agreements, caps, floors, collars, and certain interest rate lock commitments and forward sales of securities related to mortgage banking activities. HTLF's current strategy includes the use of interest rate swaps, interest rate lock commitments and forward sales of mortgage securities. In addition, HTLF is facilitating back-to-back loan swaps to assist customers in managing their interest rate risk while executing offsetting interest rate swaps with dealer counterparties. HTLF'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 amounts to be exchanged between the counterparties. HTLF is exposed to credit risk in the event of nonperformance by counterparties to financial instruments. HTLF minimizes this risk by entering into derivative contracts with counterparties that meet HTLF’s credit standards, and the contracts contain collateral provisions protecting the at-risk party. HTLF has not experienced any losses from nonperformance by these counterparties. HTLF monitors counterparty risk in accordance with the provisions of ASC 815. In addition, interest rate-related derivative instruments generally 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 the credit ratings of each counterparty. HTLF was required to pledge no cash as collateral at both June 30, 2022 and December 31, 2021. At both June 30, 2022 and December 31, 2021, no collateral was required to be pledged by HTLF's counterparties. HTLF's derivative and hedging instruments are recorded at fair value on the consolidated balance sheets. See Note 7, "Fair Value," for additional fair value information and disclosures. Cash Flow Hedges During the third quarter of 2021, the interest rate swap transactions associated with Heartland Financial Statutory VI and VII were terminated, and the debt was converted to variable rate subordinated debentures. In addition, HTLF had two swap transactions associated with an unaffiliated bank, one of which matured in the second quarter, and the other was terminated in the third quarter. The underlying debt with the unaffiliated bank was paid off in the third quarter of 2021. For the next twelve months, HTLF estimates that cash payments and reclassification from accumulated other comprehensive income (loss) to interest expense related to the terminated swaps will total $733,000. At both June 30, 2022 and December 31, 2021, HTLF had no derivative instruments designated as cash flow hedges. Fair Value Hedges HTLF uses interest rate swaps to convert certain long term fixed rate loans to floating rates to hedge interest rate risk exposure. HTLF uses hedge accounting in accordance with ASC 815, with the 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, being recorded in the consolidated statements of income. The ineffective portions of the unrealized gains or losses, if any, are recorded in interest income and interest expense 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 the 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 was required to pledge $481,000 and $3.8 million of cash as collateral for these fair value hedges at June 30, 2022, and December 31, 2021, respectively. The table below identifies the notional amount, fair value and balance sheet category of HTLF's fair value hedges at June 30, 2022, and December 31, 2021, in thousands: Notional Amount Fair Value Balance Sheet Category June 30, 2022 Fair value hedges $ 1,287 $ 17 Other assets December 31, 2021 Fair value hedges $ 16,755 $ (1,208) Other liabilities The table below identifies the gains and losses recognized on HTLF's fair value hedges for the three- and six- months ended June 30, 2022, and June 30, 2021, in thousands: Three Months Ended Six Months Ended 2022 2021 2022 2021 Gain recognized in interest income on fair value hedges $ 42 $ 132 $ 1,225 $ 895 Embedded Derivatives HTLF has fixed rate loans with embedded derivatives. These loans contain terms that affect the cash flows or value of the loan similar to a derivative instrument, and therefore are considered to contain an embedded derivative. The embedded derivatives are bifurcated from the loans because the terms of the derivative instrument are not clearly and closely related to the loans. The embedded derivatives are recorded at fair value on the consolidated balance sheets as a part of other assets, and changes in the fair value are a component of noninterest income. The table below identifies the notional amount, fair value and balance sheet category of the embedded derivatives at June 30, 2022, and December 31, 2021, in thousands: Notional Amount Fair Value Balance Sheet Category June 30, 2022 Embedded derivatives $ 6,207 $ 8 Other assets December 31, 2021 Embedded derivatives $ 7,496 $ (317) Other liabilities The table below identifies the gains and losses recognized on HTLF's embedded derivatives for the three- and six- months ended June 30, 2022, and June 30, 2021, in thousands: Three Months Ended Six Months Ended 2022 2021 2022 2021 Gain (loss) recognized in other noninterest income on embedded derivatives $ 100 $ (54) $ 325 $ (183) Back-to-Back Loan Swaps HTLF has interest rate swap loan relationships with customers to meet their financing needs. Upon entering into these loan swaps, HTLF enters into offsetting positions with counterparties in order to minimize interest rate risk. 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. HTLF was required to post $945,000 of collateral at June 30, 2022 compared to $24.1 million as of December 31, 2021, respectively, as collateral related to these back-to-back swaps. HTLF's counterparties were required to pledge $24.2 million at June 30, 2022 compared to $0 at December 31, 2021. Any gains and losses on these back-to-back swaps are recorded in noninterest income on the consolidated statements of income, and for the three and six months ended June 30, 2022 and June 30, 2021, no gain or loss was recognized. The table below identifies the balance sheet category and fair values of the derivative instruments designated as loan swaps at June 30, 2022, and December 31, 2021, in thousands: Notional Fair Balance Sheet Weighted Weighted June 30, 2022 Customer interest rate swaps $ 675,070 $ 19,029 Other assets 4.24 % 4.34 % Customer interest rate swaps 675,070 (19,029) Other liabilities 4.34 4.24 December 31, 2021 Customer interest rate swaps $ 463,069 $ 23,574 Other assets 4.44 % 2.35 % Customer interest rate swaps 463,069 (23,574) Other liabilities 2.35 4.44 Other Free Standing Derivatives HTLF has entered into interest rate lock commitments to originate residential mortgage loans held for sale and forward commitments to sell residential mortgage loans and mortgage backed securities that are considered derivative instruments. HTLF enters into forward commitments for the future delivery of residential mortgage loans when interest rate lock commitments are entered into and to economically hedge the effect of future changes in interest rates on the commitments to fund the loans as well as on residential mortgage loans available for sale. 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. HTLF was required to pledge no collateral at both June 30, 2022, and December 31, 2021. HTLF's counterparties were required to pledge no collateral at both June 30, 2022 and December 31, 2021, as collateral for these forward commitments. HTLF acquired undesignated interest rate swaps in 2015. These swaps were entered into primarily for the benefit of customers seeking to manage their interest rate risk and are not designated against specific assets or liabilities on the consolidated balance sheets or forecasted transactions and therefore do not qualify for hedge accounting in accordance with ASC 815. These swaps are carried at fair value on the consolidated balance sheets as a component of other liabilities, with changes in the fair value recorded as a component of other noninterest income. The table below identifies the balance sheet category and fair values of HTLF's other free standing derivative instruments not designated as hedging instruments at June 30, 2022, and December 31, 2021, in thousands: Balance Sheet Category Notional Amount Fair Value June 30, 2022 Interest rate lock commitments (mortgage) Other assets $ 32,651 $ 955 Forward commitments Other assets 27,500 201 Forward commitments Other liabilities 17,500 (196) Undesignated interest rate swaps Other liabilities 6,207 (8) December 31, 2021 Interest rate lock commitments (mortgage) Other assets $ 37,046 $ 1,306 Forward commitments Other assets 19,000 32 Forward commitments Other liabilities 35,500 (95) Undesignated interest rate swaps Other assets 7,496 317 HTLF recognizes gains and losses on other free standing derivatives in two separate income statement categories.

FAIR VALUE

FAIR VALUE	6 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE	FAIR VALUE HTLF utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Securities carried at fair value, which include available for sale, trading securities and equity securities with a readily determinable fair value, and derivatives are recorded in the consolidated balance sheets at fair value on a recurring basis. Additionally, from time to time, HTLF may be required to record at fair value other assets on a nonrecurring basis such as loans held for sale, loans held to maturity and certain other assets including, but not limited to, mortgage servicing rights, commercial servicing rights and other real estate owned. These nonrecurring fair value adjustments typically involve application of the lower of cost or fair value accounting or write-downs of individual assets. Fair Value Hierarchy Under ASC 820, assets and liabilities are grouped at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are: Level 1 — Valuation is based upon quoted prices for identical instruments in active markets. Level 2 — Valuation is based upon quoted prices for similar instruments in active markets, or similar instruments in markets that are not active, and model-based valuation techniques for all significant assumptions are observable in the market. 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. The following is a description of valuation methodologies used for assets and liabilities recorded at fair value on a recurring or non-recurring basis. Securities Available for Sale and Held to Maturity Securities available for sale are recorded at fair value on a recurring basis. Securities held to maturity are generally recorded at cost. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security's credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange, as well as U.S. Treasury securities. Level 2 securities include U.S. government and agency securities, mortgage and asset-backed securities and private collateralized mortgage obligations, municipal bonds and corporate debt securities. On a quarterly basis, a secondary independent pricing service is used for the securities portfolio to validate the pricing from HTLF's primary pricing service. Equity Securities with a Readily Determinable Fair Value Equity securities with a readily determinable fair value generally include Community Reinvestment Act mutual funds and are classified as Level 2 due to the infrequent trading of these securities. The fair value is based on the price per share. Loans Held for Sale Loans held for sale are carried at the lower of cost or fair value on an aggregate basis. The fair value of loans held for sale is based on what secondary markets are currently offering for portfolios with similar characteristics. As such, HTLF classifies loans held for sale subjected to nonrecurring fair value adjustments as Level 2. Loans Held to Maturity HTLF does not record loans held to maturity at fair value on a recurring basis. However, from time to time, certain loans are considered collateral dependent and an allowance for credit losses is established. The fair value of individually assessed loans is measured using the fair value of the collateral. In accordance with ASC 820, individually assessed loans measured at fair value are classified as nonrecurring Level 3 in the fair value hierarchy. Premises, Furniture and Equipment Held for Sale HTLF values premises, furniture and equipment held for sale based on third-party appraisals less estimated disposal costs. HTLF considers third party appraisals, as well as independent fair value assessments from realtors or persons involved in selling bank premises, furniture and equipment, in determining the fair value of particular properties. Accordingly, the valuation of premises, furniture and equipment held for sale is subject to significant external and internal judgment. HTLF periodically reviews premises, furniture and equipment held for sale to determine if the fair value of the property, less disposal costs, has declined below its recorded book value and records any adjustments accordingly. Premises, furniture and equipment held for sale are classified as nonrecurring Level 3 in the fair value hierarchy. Mortgage Servicing Rights Mortgage servicing rights assets represent the value associated with servicing residential real estate loans that have been sold to outside investors with servicing retained. The fair value for servicing assets is determined through discounted cash flow analysis and utilizes discount rates, prepayment speeds and delinquency rate assumptions as inputs. All of the assumptions in the discounted cash flow analysis require a significant degree of management estimation and judgment. Mortgage servicing rights are subject to impairment testing. The carrying values of these rights are reviewed quarterly for impairment based upon the calculation of fair value as performed by an outside third party. For purposes of measuring impairment, the rights are stratified into certain risk characteristics including note type and note term. If the valuation model reflects a fair value less than the carrying value, mortgage servicing rights are adjusted to fair value through a valuation allowance. HTLF classifies mortgage servicing rights as nonrecurring with Level 3 measurement inputs. Derivative Financial Instruments HTLF's current interest rate risk strategy includes interest rate swaps. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. To comply with the provisions of ASC 820, HTLF incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty's nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, HTLF has considered the impact of netting any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. Although HTLF has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of June 30, 2022, and December 31, 2021, HTLF has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, HTLF has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. Interest rate lock commitments HTLF uses an internal valuation model that relies on internally developed inputs to estimate the fair value of its interest rate lock commitments which is based on unobservable inputs that reflect management's assumptions and specific information about each borrower. Interest rate lock commitments are classified in Level 3 of the fair value hierarchy. Forward commitments The fair value of forward commitments are estimated using an internal valuation model, which includes current trade pricing for similar financial instruments in active markets that HTLF has the ability to access and are classified in Level 2 of the fair value hierarchy. Other Real Estate Owned Other real estate owned ("OREO") represents property acquired through foreclosures and settlements of loans. Property acquired is carried at the fair value of the property at the time of acquisition (representing the property's cost basis), plus any acquisition costs, or the estimated fair value of the property, less disposal costs. HTLF considers third party appraisals, as well as independent fair value assessments from realtors or persons involved in selling OREO, in determining the fair value of particular properties. Accordingly, the valuation of OREO is subject to significant external and internal judgment. HTLF periodically reviews OREO to determine if the fair value of the property, less disposal costs, has declined below its recorded book value and records any adjustments accordingly. OREO is classified as nonrecurring Level 3 of the fair value hierarchy. The table below presents HTLF's assets and liabilities that are measured at fair value on a recurring basis as of June 30, 2022, and December 31, 2021, in thousands, aggregated by the level in the fair value hierarchy within which those measurements fall: Total Fair Value Level 1 Level 2 Level 3 June 30, 2022 Assets Securities available for sale U.S. treasuries $ 13,890 $ 13,890 $ — $ — U.S. agencies 45,216 — 45,216 — Obligations of states and political subdivisions 1,665,343 — 1,665,343 — Mortgage-backed securities - agency 1,965,309 — 1,965,309 — Mortgage-backed securities - non-agency 2,192,437 — 2,192,437 — Commercial mortgage-backed securities - agency 97,851 — 97,851 — Commercial mortgage-backed securities - non-agency 714,241 — 714,241 — Asset-backed securities 382,822 — 382,822 — Corporate bonds 8,672 — 8,672 — Equity securities with a readily determinable fair value 20,437 — 20,437 — Derivative financial instruments (1) 19,054 — 19,054 — Interest rate lock commitments 955 — — 955 Forward commitments 201 — 201 — Total assets at fair value $ 7,126,428 $ 13,890 $ 7,111,583 $ 955 Liabilities Derivative financial instruments (2) $ 19,037 $ — $ 19,037 $ — Forward commitments 196 — 196 — Total liabilities at fair value $ 19,233 $ — $ 19,233 $ — December 31, 2021 Assets Securities available for sale U.S. treasuries $ 1,008 $ 1,008 $ — $ — U.S. agencies 193,384 — 193,384 — Obligations of states and political subdivisions 2,085,033 — 2,085,033 — Mortgage-backed securities - agency 2,349,289 — 2,349,289 — Mortgage-backed securities - non-agency 1,743,379 — 1,743,379 — Commercial mortgage-backed securities - agency 123,912 — 123,912 — Commercial mortgage-backed securities - non-agency 600,888 — 600,888 — Asset-backed securities 409,653 — 409,653 — Corporate bonds 3,040 — 3,040 — Equity securities with a readily determinable fair value 20,788 — 20,788 — Derivative financial instruments (2) 23,891 — 23,891 — Interest rate lock commitments 1,306 — — 1,306 Forward commitments 32 — 32 — Total assets at fair value $ 7,555,603 $ 1,008 $ 7,553,289 $ 1,306 Liabilities Derivative financial instruments (3) $ 25,099 $ — $ 25,099 $ — Forward commitments 95 — 95 — Total liabilities at fair value $ 25,194 $ — $ 25,194 $ — (1) Includes fair value hedges, embedded derivatives and back-to-back loan swaps.

(4) The significant unobservable input used in the discounted cash flow analysis are the discount rate and constant prepayment rate. The changes in fair value of the interest rate lock commitments, which are Level 3 financial instruments measured on a recurring basis, are summarized in the following table, in thousands: For the Six Months Ended For the Year Ended Balance at January 1, $ 1,306 $ 1,827 Total net gains included in earnings (672) (2,345) Issuances 2,494 15,403 Settlements (2,173) (13,579) Balance at period end $ 955 $ 1,306 Gains included in gains (losses) on sale of loans held for sale attributable to interest rate lock commitments held at June 30, 2022, and December 31, 2021, were $955,000 and $1.3 million, respectively. The table below is a summary of the estimated fair value of HTLF's financial instruments (as defined by ASC 825) as of June 30, 2022, and December 31, 2021, in thousands. The carrying amounts in the following tables are recorded in the consolidated balance sheets under the indicated captions. In accordance with ASC 825, the assets and liabilities that are not financial instruments are not included in the disclosure, including the value of the commercial and mortgage servicing rights, premises, furniture and equipment, premises, furniture and equipment held for sale, OREO, goodwill, and other intangibles and other liabilities. HTLF does not believe that the estimated information presented herein is representative of the earnings power or value of HTLF. The following analysis, which is inherently limited in depicting fair value, also does not consider any value associated with either existing customer relationships or the ability of HTLF to create value through loan origination, deposit gathering or fee generating activities. Many of the estimates presented herein are based upon the use of highly subjective information and assumptions and, accordingly, the results may not be precise. Management believes that fair value estimates may not be comparable between financial institutions due to the wide range of permitted valuation techniques and numerous estimates which must be made. Furthermore, because the disclosed fair value amounts were estimated as of the balance sheet date, the amounts actually realized or paid upon maturity or settlement of the various financial instruments could be significantly different.

(2) Includes embedded derivatives, fair value hedges, and back-to-back loan swaps. Cash and Cash Equivalents — The carrying amount is a reasonable estimate of fair value due to the short-term nature of these instruments. Time Deposits in Other Financial Institutions — The carrying amount is a reasonable estimate of fair value due to the short-term nature of these instruments. Securities — For equity securities with a readily determinable fair value and debt securities either held to maturity, available for sale or trading, fair value equals quoted market price if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities. For Level 3 securities, HTLF utilizes independent pricing provided by third party vendors or brokers. Other Investments — Fair value measurement of other investments, which consists primarily of FHLB stock, are based on their redeemable value, which is at cost due to the restrictions placed on their transferability. The market for these securities is restricted to the issuer of the stock and subject to impairment evaluation. Loans — The fair value of loans is determined using an exit price methodology. The exit price estimation of fair value is based on the present value of the expected cash flows. The projected cash flows are based on the contractual terms of the loans, adjusted for prepayments and a discount rate based on the relative risk of the cash flows. Other considerations include the loan type, remaining life of the loan and credit risk. The fair value of individually assessed or impaired loans is measured using the fair value of the underlying collateral. The fair value of loans held for sale is estimated using quoted market prices. Cash surrender value on life insurance — Life insurance policies are held on certain officers. The carrying value of these policies approximates fair value as it is based on the cash surrender value adjusted for other charges or amounts due that are probable at settlement. As such, HTLF classifies the estimated fair value of the cash surrender value on life insurance as Level 2. Derivative Financial Instruments — The fair value of all derivatives is estimated based on the amount that HTLF would pay or would be paid to terminate the contract or agreement, using current rates and prices, and, when appropriate, the current creditworthiness of the counter-party. Interest Rate Lock Commitments — The fair value of interest rate lock commitments is estimated using an internal valuation model, which includes grouping the interest rate lock commitments by interest rate and terms, applying an estimated closing ratio based on historical experience, and then multiplying by quoted investor prices determined to be reasonably applicable to the loan commitment groups based on interest rate, terms, and rate lock expiration dates of the loan commitment group. Forward Commitments — The fair value of these instruments is estimated using an internal valuation model, which includes current trade pricing for similar financial instruments. Deposits — The fair value of demand deposits, savings accounts and certain money market deposits is the amount payable on demand at the reporting date. The fair value of fixed maturity certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities. If the fair value of the fixed maturity certificates of deposit is calculated at less than the carrying amount, the carrying value of these deposits is reported as the fair value. Short-term and Other Borrowings — Rates currently available to HTLF for debt with similar terms and remaining maturities are used to estimate fair value of existing debt. Commitments to Extend Credit, Unused Lines of Credit and Standby Letters of Credit — Based upon management's analysis of the off balance sheet financial instruments, there are no significant unrealized gains or losses associated with these financial instruments based upon review of the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties.

STOCK COMPENSATION

STOCK COMPENSATION	6 Months Ended
	Jun. 30, 2022
Share-Based Payment Arrangement [Abstract]
STOCK COMPENSATION	STOCK COMPENSATION HTLF may grant, through its Compensation, Nominating and Corporate Governance Committee (the "Compensation Committee"), non-qualified and incentive stock options, stock appreciation rights, stock awards, restricted stock, restricted stock units and cash incentive awards, under its 2020 Long-Term Incentive Plan (the "Plan"). The Plan has 1,460,000 shares of common stock authorized for issuance. As of June 30, 2022, 956,640 shares of common stock were available for issuance under future awards that may be granted under the Plan to employees and directors of, and service providers to, HTLF or its subsidiaries. ASC Topic 718, "Compensation-Stock Compensation," requires the measurement of the cost of employee services received in exchange for an award of equity instruments based upon the fair value of the award on the grant date. The cost of the award is based upon its fair value estimated on the date of grant and recognized in the consolidated statements of income over the vesting period of the award. The fair market value of restricted stock and restricted stock units is based on the fair value of the underlying shares of common stock on the date of grant. Forfeitures are accounted for as they occur. HTLF's income tax expense included $129,000 of tax benefit during the six months ended June 30, 2022 and a tax benefit of $303,000 during the six months ended June 30, 2021, related to the exercise, vesting and forfeiture of equity-based awards. Restricted Stock Units The Plan permits the Compensation Committee to grant restricted stock units ("RSUs"). The time-based RSUs are generally granted in March of each year and represent the right, without payment, to receive shares of HTLF common stock on a specified date in the future. Generally, the time-based RSUs vest over three years in equal installments in March of each of the three years following the year of the grant. The Compensation Committee has also granted three-year performance-based RSUs, generally in March of each year. These performance-based RSUs will be earned based on satisfaction of performance targets for the three-year performance period as defined in the RSU agreement. These performance-based RSUs or a portion thereof may vest after measurement of performance in relation to the performance targets. The time-based RSUs may also vest upon death or disability, upon a change in control or upon a "qualified retirement" (as defined in the RSU agreement), and the three-year performance-based RSUs may also vest to the extent that they are earned upon death, disability, upon a change in control or upon a "qualified retirement" (as defined in the RSU agreement). All of HTLF's RSUs will be settled in common stock upon vesting and are not entitled to dividends until vested. A summary of the RSUs outstanding as of June 30, 2022, and June 30, 2021, and changes during the six months ended June 30, 2022 and 2021, follows: 2022 2021 Shares Weighted-Average Grant Date Shares Weighted-Average Grant Date Outstanding at January 1, 389,885 $ 44.19 348,275 $ 38.22 Granted 236,120 48.47 208,513 51.63 Vested (158,519) 45.03 (146,381) 40.89 Forfeited (25,500) 46.60 (18,861) 42.88 Outstanding at June 30, 441,986 $ 46.03 391,546 $ 44.08 Total compensation costs recorded for RSUs were $5.1 million and $4.8 million for the six months ended June 30, 2022 and 2021, respectively. As of June 30, 2022, there were $12.6 million of total unrecognized compensation costs related to the Plan for RSUs that are expected to be recognized through 2025.

BASIS OF PRESENTATION (Policies

BASIS OF PRESENTATION (Policies)	6 Months Ended
	Jun. 30, 2022
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The interim unaudited consolidated financial statements contained herein should be read in conjunction with the audited consolidated financial statements and accompanying notes to the consolidated financial statements for the fiscal year ended December 31, 2021, included in the Annual Report on Form 10-K of Heartland Financial USA, Inc. ("HTLF") filed with the Securities and Exchange Commission ("SEC") on February 24, 2022 . Foot note disclosures to the interim unaudited consolidated financial statements which would substantially duplicate the disclosure contained in the footnotes to the audited consolidated financial statements have been omitted. The financial information included herein has been prepared in accordance with U.S. generally accepted accounting principles for interim financial reporting and has been prepared pursuant to the rules and regulations for reporting on Form 10-Q and Rule 10-01 of Regulation S-X. Such information reflects all adjustments (consisting of normal recurring adjustments), that are, in the opinion of management, necessary for a fair presentation of the financial position and results of operations for the periods presented. The results of the interim period ended June 30, 2022, are not necessarily indicative of the results expected for the year ending 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.
Subsequent Events	HTLF has evaluated subsequent events that may require recognition or disclosure through the filing date of this Quarterly Report on Form 10-Q with the SEC.
Effect of New Financial Accounting Standards	ASU 2018-16 In October 2018, the FASB issued ASU 2018-16, " Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting." In the United States, eligible benchmark interest rates under Topic 815 are interest rates on direct Treasury obligations of the U.S. government, the London Interbank Offered Rate ("LIBOR") swap rate, and the Overnight Index Swap ("OIS") Rate based on the Fed Funds Effective Rate. When the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities , in August 2017, it introduced the Securities Industry and Financial Markets Association ("SIFMA") Municipal Swap Rate as the fourth permissible U.S. benchmark rate. ASU 2018-16 adds the OIS rate based on the Secured Overnight Financing Rate ("SOFR") as a U.S. benchmark interest rate to facilitate the LIBOR to SOFR transition and provide sufficient lead time for entities to prepare for changes to interest rate risk hedging strategies for both risk management and hedge accounting purposes. ASU 2018-16 became effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years and the financial statement impact immediately upon adoption was immaterial. The future financial statement impact will depend on any new contracts entered into using new benchmark rates, as well as any existing contracts that are migrated from LIBOR to new benchmark interest rates. HTLF has a formal working group that is responsible for the planning, assessment and execution of the transition from LIBOR as an interest rate benchmark to term SOFR. Currently, HTLF has adjustable rate loans, several debt obligations and securities and derivative instruments in place that reference LIBOR-based rates. HTLF’s transition plan included the cessation in new contracts of the use of LIBOR as a reference rate at December 31, 2021. ASU 2020-04 In March 2020, the FASB issued ASU 2020-04, " Reference Rate Reform, " which provides optional expedients and exceptions for applying GAAP to loan and lease agreements, derivative contracts, and other transactions affected by the anticipated transition away from LIBOR toward new interest rate benchmarks. For loan and lease agreements that are modified because of reference rate reform and that meet certain scope guidance (i) modifications of loan agreements should be accounted for by prospectively adjusting the effective interest rate, and the modifications would be considered "minor" with the result that any existing unamortized origination fees/costs would carry forward and continue to be amortized and (ii) modifications of lease agreements should be accounted for as a continuation of the existing agreement, with no reassessments of the lease classification and the discount rate or remeasurements of lease payments that otherwise would be required for modifications not accounted for as separate contracts. ASU 2020-04 also provides numerous optional expedients for derivative accounting. ASU 2020-04 is effective March 12, 2020 through December 31, 2022. An entity may elect to apply ASU 2020-04 for contract modifications as of January 1, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. Once elected for a Topic or an Industry Subtopic within the ASC, ASU 2020-04 must be applied prospectively for all eligible contract modifications for that Topic or Industry Subtopic. HTLF anticipates that ASU 2020-04 will simplify any modifications executed between the selected start date and December 31, 2022 that are directly related to LIBOR transition by allowing prospective recognition of the continuation of the contract, rather than extinguishment of the old contract that would result in writing off unamortized fees/costs. Management will continue to actively assess the impacts of ASU 2020-04 and the related opportunities and risks involved in the LIBOR transition. ASU 2022-02 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
Fair Value Hierarchy	Under ASC 820, assets and liabilities are grouped at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are: Level 1 — Valuation is based upon quoted prices for identical instruments in active markets. Level 2 — Valuation is based upon quoted prices for similar instruments in active markets, or similar instruments in markets that are not active, and model-based valuation techniques for all significant assumptions are observable in the market. 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. The following is a description of valuation methodologies used for assets and liabilities recorded at fair value on a recurring or non-recurring basis. Securities Available for Sale and Held to Maturity Securities available for sale are recorded at fair value on a recurring basis. Securities held to maturity are generally recorded at cost. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security's credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange, as well as U.S. Treasury securities. Level 2 securities include U.S. government and agency securities, mortgage and asset-backed securities and private collateralized mortgage obligations, municipal bonds and corporate debt securities. On a quarterly basis, a secondary independent pricing service is used for the securities portfolio to validate the pricing from HTLF's primary pricing service. Equity Securities with a Readily Determinable Fair Value Equity securities with a readily determinable fair value generally include Community Reinvestment Act mutual funds and are classified as Level 2 due to the infrequent trading of these securities. The fair value is based on the price per share. Loans Held for Sale Loans held for sale are carried at the lower of cost or fair value on an aggregate basis. The fair value of loans held for sale is based on what secondary markets are currently offering for portfolios with similar characteristics. As such, HTLF classifies loans held for sale subjected to nonrecurring fair value adjustments as Level 2. Loans Held to Maturity HTLF does not record loans held to maturity at fair value on a recurring basis. However, from time to time, certain loans are considered collateral dependent and an allowance for credit losses is established. The fair value of individually assessed loans is measured using the fair value of the collateral. In accordance with ASC 820, individually assessed loans measured at fair value are classified as nonrecurring Level 3 in the fair value hierarchy. Premises, Furniture and Equipment Held for Sale HTLF values premises, furniture and equipment held for sale based on third-party appraisals less estimated disposal costs. HTLF considers third party appraisals, as well as independent fair value assessments from realtors or persons involved in selling bank premises, furniture and equipment, in determining the fair value of particular properties. Accordingly, the valuation of premises, furniture and equipment held for sale is subject to significant external and internal judgment. HTLF periodically reviews premises, furniture and equipment held for sale to determine if the fair value of the property, less disposal costs, has declined below its recorded book value and records any adjustments accordingly. Premises, furniture and equipment held for sale are classified as nonrecurring Level 3 in the fair value hierarchy. Mortgage Servicing Rights Mortgage servicing rights assets represent the value associated with servicing residential real estate loans that have been sold to outside investors with servicing retained. The fair value for servicing assets is determined through discounted cash flow analysis and utilizes discount rates, prepayment speeds and delinquency rate assumptions as inputs. All of the assumptions in the discounted cash flow analysis require a significant degree of management estimation and judgment. Mortgage servicing rights are subject to impairment testing. The carrying values of these rights are reviewed quarterly for impairment based upon the calculation of fair value as performed by an outside third party. For purposes of measuring impairment, the rights are stratified into certain risk characteristics including note type and note term. If the valuation model reflects a fair value less than the carrying value, mortgage servicing rights are adjusted to fair value through a valuation allowance. HTLF classifies mortgage servicing rights as nonrecurring with Level 3 measurement inputs. Derivative Financial Instruments HTLF's current interest rate risk strategy includes interest rate swaps. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. To comply with the provisions of ASC 820, HTLF incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty's nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, HTLF has considered the impact of netting any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. Although HTLF has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of June 30, 2022, and December 31, 2021, HTLF has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, HTLF has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. Interest rate lock commitments HTLF uses an internal valuation model that relies on internally developed inputs to estimate the fair value of its interest rate lock commitments which is based on unobservable inputs that reflect management's assumptions and specific information about each borrower. Interest rate lock commitments are classified in Level 3 of the fair value hierarchy. Forward commitments The fair value of forward commitments are estimated using an internal valuation model, which includes current trade pricing for similar financial instruments in active markets that HTLF has the ability to access and are classified in Level 2 of the fair value hierarchy. Other Real Estate Owned Other real estate owned ("OREO") represents property acquired through foreclosures and settlements of loans. Property acquired is carried at the fair value of the property at the time of acquisition (representing the property's cost basis), plus any acquisition costs, or the estimated fair value of the property, less disposal costs. HTLF considers third party appraisals, as well as independent fair value assessments from realtors or persons involved in selling OREO, in determining the fair value of particular properties. Accordingly, the valuation of OREO is subject to significant external and internal judgment. HTLF periodically reviews OREO to determine if the fair value of the property, less disposal costs, has declined below its recorded book value and records any adjustments accordingly. OREO is classified as nonrecurring Level 3 of the fair value hierarchy.

The closing ratio calculation takes into consideration historical data and loan-level data. (2) Third party appraisals are obtained and updated at least annually to establish the value of the underlying asset, but the disclosure of the unobservable inputs used by the appraisers would not be meaningful because the range will vary widely from appraisal to appraisal. (3) Discounts applied to the appraised values primarily include estimated sales costs, but also consider the age of the appraisal, changes in local market conditions and changes in the current condition of the collateral. (4) The significant unobservable input used in the fair value measurement are the value indices, which are weighted-average spreads to LIBOR based on maturity groups.

The closing ratio calculation takes into consideration historical data and loan-level data. (2) Third party appraisals are obtained and updated at least annually to establish the value of the underlying asset, but the disclosure of the unobservable inputs used by the appraisers would not be meaningful because the range will vary widely from appraisal to appraisal. (3) Discounts applied to the appraised values primarily include estimated sales costs, but also consider the age of the appraisal, changes in local market conditions and changes in the current condition of the collateral. (4) The significant unobservable input used in the discounted cash flow analysis are the discount rate and constant prepayment rate.
Fair Value, Assets Measured on Recurring Basis, Unobservable Input Reconciliation	The changes in fair value of the interest rate lock commitments, which are Level 3 financial instruments measured on a recurring basis, are summarized in the following table, in thousands: For the Six Months Ended For the Year Ended Balance at January 1, $ 1,306 $ 1,827 Total net gains included in earnings (672) (2,345) Issuances 2,494 15,403 Settlements (2,173) (13,579) Balance at period end $ 955 $ 1,306
Fair Value, by Balance Sheet Grouping	HTLF does not believe that the estimated information presented herein is representative of the earnings power or value of HTLF. The following analysis, which is inherently limited in depicting fair value, also does not consider any value associated with either existing customer relationships or the ability of HTLF to create value through loan origination, deposit gathering or fee generating activities. Many of the estimates presented herein are based upon the use of highly subjective information and assumptions and, accordingly, the results may not be precise. Management believes that fair value estimates may not be comparable between financial institutions due to the wide range of permitted valuation techniques and numerous estimates which must be made. Furthermore, because the disclosed fair value amounts were estimated as of the balance sheet date, the amounts actually realized or paid upon maturity or settlement of the various financial instruments could be significantly different.
