Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business and Significant Accounting Policies	Nature of Business and Significant Accounting Policies Nature of Business MidWest One Financial Group, Inc. (the "Company"), an Iowa corporation formed in 1983, is a bank holding company under the BHCA and a financial holding company under the GLBA. Our principal executive offices are located at 102 South Clinton Street, Iowa City, Iowa 52240. The Company owns all of the outstanding common stock of MidWest One Bank, an Iowa state non-member bank chartered in 1934 with its main office in Iowa City, Iowa. We operate primarily through MidWest One Bank, our bank subsidiary. On June 9, 2022, the Company acquired Iowa First Bancshares Corp., a bank holding company whose wholly-owned banking subsidiaries were First National Bank of Muscatine and First National Bank in Fairfield, community banks located in Muscatine and Fairfield, Iowa, respectively. Immediately following the completion of the acquisition, First National Bank of Muscatine and First National Bank in Fairfield were merged with and into the Bank. As consideration for the merger, we paid cash in the amount of $46.7 million. Basis of Presentation The accompanying interim condensed consolidated financial statements are prepared in accordance with GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X of the Securities Exchange Act of 1934. Accordingly, certain disclosures accompanying annual consolidated financial statements are omitted. In the opinion of management, all significant intercompany accounts and transactions have been eliminated and adjustments, consisting solely of normal recurring accruals and considered necessary for the fair presentation of financial statements for the interim periods, have been included. The current period's results of operations are not necessarily indicative of the results that ultimately may be achieved for the year. The interim condensed consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Form 10-K for the year ended December 31, 2021, filed with the SEC on March 10, 2022. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect: (1) the reported amounts of assets and liabilities, (2) the disclosure of contingent assets and liabilities at the date of the financial statements, and (3) the reported amounts of revenues and expenses during the reporting period. These estimates are based on information available to management at the time the estimates are made. Actual results could differ from those estimates. The results for the six months ended June 30, 2022 may not be indicative of results for the year ending December 31, 2022, or for any other period. All significant accounting policies followed in the preparation of the quarterly financial statements are disclosed in the Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on March 10, 2022, except for the policies related to held to maturity debt securities and acquired loans. Held to Maturity Debt Securities - Certain debt securities that the Company has the positive intent and ability to hold to maturity are classified as held to maturity and recorded at amortized cost. A debt security is placed on nonaccrual status at the time any principal or interest payments become 90 days delinquent. Interest accrued but not received for a security placed on nonaccrual is reversed against interest income. The Company evaluates debt securities held to maturity for current expected credit losses. Held-to-maturity securities are evaluated on a quarterly basis using historical probability of default and loss given default information specific to the investment category. If this evaluation determines that credit losses exist, an allowance for credit loss is recorded and included in earnings as a component of credit loss expense. The Company's mortgage-backed securities and collateralized mortgage obligations are issued by U.S. government agencies and U.S. government-sponsored enterprises and are implicitly guaranteed by the U.S. government, and as such are excluded from the credit loss evaluation. Accrued interest receivable on held to maturity debt securities is recorded within 'Other Assets,' and is excluded from the estimate of credit losses. Acquired Loans - Acquired loans are separated into two categories based on the credit risk characteristics of the underlying borrowers as either PCD, for loans which have experienced more than insignificant credit deterioration since origination, or loans with no credit deterioration (non-PCD). At the date of acquisition, an ACL on PCD loans is determined and added to the amortized cost basis of the individual loans. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. The ACL on PCD loans is recorded in the acquisition accounting and no provision for credit losses is recognized at the acquisition date. Subsequent changes to the ACL are recorded through provision expense. For non-PCD loans, an ACL is established immediately after the acquisition through a charge to the provision for credit losses. Segment Reporting The Company’s activities are considered to be one reportable segment for financial reporting purposes. The Company is engaged in the business of commercial and retail banking and trust and investment management services with operations throughout central and eastern Iowa, the Minneapolis/St. Paul metropolitan area of Minnesota, southwestern Wisconsin, Naples and Fort Myers, Florida, and Denver, Colorado. Substantially all income is derived from a diverse base of commercial, mortgage and retail lending activities, and investments. Effect of New Financial Accounting Standards Accounting Guidance Pending Adoption at June 30, 2022 On March 12, 2020, the FASB issued ASU 2020-04, Reference Rate Reform (ASC 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . ASC 848 contains optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform. Certain optional expedients and exceptions for contract modifications and hedging relationships were amended in ASU 2021-01, Reference Rate Reform (Topic 848): Scope Refinement , issued on January 7, 2021. Entities may apply the provision as of the beginning of the reporting period when the election is made and are available until December 31, 2022. The adoption of ASU ASU 2020-04 is not expected to have a material impact on the Company’s consolidated financial statements. On March 31, 2022, the FASB issued ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. For creditors that have adopted the CECL accounting guidance within ASU 2016-13, the amendments eliminate the accounting guidance for TDRs within ASC 310-40, while also enhancing the disclosure requirements for certain loan refinancings and restructurings when a borrower is experiencing financial difficulty. In addition, public business entities must also disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of ASC 326-20. The amendments are effective for fiscal years beginning after December 15, 2022 and should be applied prospectively, with an option to apply a modified retrospective transition approach for the recognition and measurement of TDRs. The Company is currently evaluating the impact of ASU 2022-02.

The primary reasons for the acquisition were to enter the Muscatine, Iowa market and increase our presence in Fairfield, Iowa. Immediately following the completion of the acquisition, First National Bank of Muscatine and First National Bank in Fairfield were merged with and into the Bank. The assets acquired and liabilities assumed have been accounted for under the acquisition method of accounting. The assets and liabilities, both tangible and intangible, were recorded at their fair values as of the June 9, 2022 acquisition date net of any applicable tax effects using a methodology similar to the Company's legacy assets and liabilities (refer to Note 14. Fair Value of Financial Instruments and Fair Value Measurements for additional information regarding the fair value methodology). Initial accounting for the assets acquired and liabilities assumed was incomplete at June 30, 2022. Thus, such amounts recognized in the financial statements have been determined to be provisional. The bargain purchase gain, which is recorded in 'Other' noninterest income, was generated as a result of the estimated fair value of identifiable net assets acquired exceeding the merger consideration, based on provisional fair values. The revenue and earnings amount specific to IOFB since the acquisition date that are included in the consolidated results for the three and six months ended June 30, 2022 are not readily determinable. The disclosures of these amounts are impracticable due to the merging of certain processes and systems at the acquisition date. The table below summarizes the amounts recognized as of the acquisition date for each major class of assets acquired and liabilities assumed: (in thousands) June 9, 2022 Merger consideration Cash consideration $ 46,672 Identifiable net assets acquired, at fair value Assets acquired Cash and due from banks $ 10,192 Interest earning deposits in banks 67,855 Investment securities 119,230 Total loans held for investment, net 281,470 Premises and equipment 7,363 Core deposit intangible 16,500 Other assets 12,218 Total assets acquired 514,828 Liabilities assumed Deposits (463,638) Other liabilities (3,117) Total liabilities assumed (466,755) Total fair value of identifiable net assets 48,073 Bargain Purchase Gain $ 1,401 Of the $281.5 million net loans acquired, $11.1 million exhibited credit deterioration on the date of purchase. The following table provides a summary of these PCD loans at acquisition: (in thousands) June 9, 2022 Par value of PCD loans acquired $ 15,396 PCD ACL at acquisition (3,371) Non-credit discount on PCD loans (933) Purchase price of PCD loans $ 11,092 For illustrative purposes only, the following table presents certain unaudited pro forma information for the three and six months ended June 30, 2022 and 2021. This unaudited, estimated pro forma information was calculated as if IOFB had been acquired as of the beginning of the year prior to the date of acquisition. This unaudited pro forma information combines the historical results of IOFB and the Company and includes adjustments for the estimated impact of certain fair value purchase accounting, interest expense, acquisition-related expenses, and income tax expense for the respective periods. The pro forma information is not indicative of what would have occurred had the acquisition occurred as of the beginning of the year prior to the acquisition. Additionally, MidWest One expects to achieve further operating cost savings and other business synergies, including revenue growth as a result of the acquisition, which are not reflected in the pro forma amounts that follow. As a result, actual amounts would have differed from the unaudited pro forma information presented.

Debt Securities [Abstract]
Debt Securities	Debt Securities On January 1, 2022, the Company transferred, at fair value, $1.25 billion of mortgage-backed securities, collateralized mortgage obligations, and securities issued by state and political subdivisions from the available for sale classification to the held to maturity classification. The net unrealized after tax loss of $11.5 million associated with those re-classified securities remained in accumulated other comprehensive loss and will be amortized over the remaining life of the securities. No gains or losses were recognized in earnings at the time of the transfer. The following tables summarize the amortized cost, gross unrealized gains and losses and the resulting fair value of debt securities for the periods indicated. There were no held to maturity debt securities as of December 31, 2021.

Accrued interest receivable on available for sale debt securities and held to maturity debt securities is recorded within 'Other Assets,' and is excluded from the estimate of credit losses. At June 30, 2022 the accrued interest receivable on available for sale debt securities and held to maturity debt securities totaled $7.4 million and $3.9 million, respectively. At December 31, 2021 the accrued interest receivable on available for sale debt securities totaled $9.5 million. There was no accrued interest receivable on held to maturity debt securities at December 31, 2021.

Management evaluated these securities through a process that included consideration of credit agency ratings and payment history. In addition, management may evaluate securities by considering the yield spread to treasury securities and the most recent financial information available. Based on this evaluation, management concluded that the decline in fair value was not attributable to credit losses. As of June 30, 2022, 15 mortgage-backed securities and 20 collateralized mortgage obligations with unrealized losses totaling $17.6 million were held by the Company. Management evaluated the payment history of these securities. In addition, management considered the implied U.S. government guarantee of these agency securities and the level of credit enhancement for non-agency securities. Based on this evaluation, management concluded that the decline in fair value was not attributable to credit losses. As of June 30, 2022, 141 corporate debt securities with total unrealized losses of $47.1 million were held by the Company. Management evaluated these securities by considering credit agency ratings and payment history. In addition, management may evaluate securities by considering the yield spread to treasury securities and the most recent financial information available. Based on this evaluation, management concluded that the decline in fair value was not attributable to credit losses. The following table presents debt securities AFS in an unrealized loss position for which an allowance for credit losses has not been recorded at December 31, 2021, aggregated by investment category and length of time in a continuous loss position: As of December 31, 2021 Available for Sale Number of Securities Less than 12 Months 12 Months or More Total Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses (in thousands, except number of securities) State and political subdivisions 136 $ 311,960 $ 5,216 $ 15,343 $ 420 $ 327,303 $ 5,636 Mortgage-backed securities 6 43,319 631 80 — 43,399 631 Collateralized mortgage obligations 44 605,729 15,693 61,984 2,627 667,713 18,320 Corporate debt securities 52 303,750 4,567 27,071 1,838 330,821 6,405 Total 238 $ 1,264,758 $ 26,107 $ 104,478 $ 4,885 $ 1,369,236 $ 30,992 The Company evaluates debt securities held to maturity for current expected credit losses. There were no debt securities held to maturity classified as nonaccrual or past due as of June 30, 2022. Held-to-maturity securities are evaluated on a quarterly basis using historical probability of default and loss given default information specific to the investment category. If this evaluation determines that credit losses exist, an allowance for credit loss is recorded and included in earnings as a component of credit loss expense. Based on this evaluation, management concluded that no allowance for credit loss for these securities was required.

Non-accrual and Delinquent Status Loans are placed on non-accrual when (1) payment in full of principal and interest is no longer expected or (2) principal or interest has been in default for 90 days or more unless the loan is both well secured with marketable collateral and in the process of collection. All loans rated doubtful or worse, and certain loans rated substandard, are placed on non-accrual. A non-accrual loan may be restored to an accrual status when (1) all past due principal and interest has been paid (excluding renewals and modifications that involve the capitalizing of interest) or (2) the loan becomes well secured with marketable collateral and is in the process of collection. An established track record of performance is also considered when determining accrual status. Loans are considered past due or delinquent when the contractual principal or interest due in accordance with the terms of the loan agreement or any portion thereof remains unpaid after the due date of the scheduled payment.

Credit Quality Information The Company aggregates loans into risk categories based on relevant information about the ability of borrowers to service their debt, such as: current financial information, historical payment experience, credit documentation, and other factors. The Company analyzes loans individually to classify the loans as to credit risk. This analysis includes non-homogenous loans, such as agricultural, commercial and industrial, and commercial real estate loans. Loans not meeting the criteria described below that are analyzed individually are considered to be pass-rated. The Company uses the following definitions for risk ratings: Special Mention/Watch - A special mention/watch asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Company’s credit position at some future date. Special mention/watch assets are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification. Substandard - Substandard loans are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Doubtful - Loans classified as doubtful have all the weaknesses inherent in those classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently known facts, conditions and values, highly questionable and improbable. Loss - Loans classified as loss are considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value but rather it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be affected in the future. Homogenous loans, including residential real estate and consumer loans, are not individually risk rated. Instead, these loans are categorized based on performance: performing and nonperforming. Nonperforming loans include those loans on nonaccrual and loans greater than 90 days past due and on accrual.

The increase in the ACL between the six-months ended June 30, 2021 and the six-months ended June 30, 2022 is reflective of the initial allowance for credit losses of $3.4 million recorded for the PCD loans acquired, as well as $3.1 million related to the acquired non-PCD loans.

Net loan charge-offs were $2.5 million for the six-months ended June 30, 2022 as compared to net loan charge-offs of $0.7 million for the six-months ended June 30, 2021.

Derivatives, Hedging Activities and Balance Sheet Offsetting	Derivatives, Hedging Activities and Balance Sheet Offsetting The following table presents the total notional amounts and gross fair values of the Company’s derivatives as of the dates indicated. The derivative asset and liability balances are presented on a gross basis, prior to the application of master netting agreements, as included in other assets and other liabilities, respectively, on the consolidated balance sheets. The fair values of the Company's derivative instrument assets and liabilities are summarized as follows: As of June 30, 2022 As of December 31, 2021 Notional Amount Fair Value Notional Amount Fair Value (in thousands) Assets Liabilities Assets Liabilities Designated as hedging instruments: Fair value hedges: Interest rate swaps $ 24,414 $ 1,541 $ — $ 24,802 $ 424 $ 1,400 Total $ 24,414 $ 1,541 $ — $ 24,802 $ 424 $ 1,400 Not designated as hedging instruments: Interest rate swaps $ 339,518 $ 14,560 $ 14,562 $ 356,636 $ 5,352 $ 5,363 RPAs - protection sold 4,105 — — 4,229 — — RPAs - protection purchased 9,528 — — 9,629 — 2 Interest rate lock commitments 8,710 112 — 17,438 330 — Interest rate forward loan sales contracts 11,242 — 5 22,710 — (24) Total $ 373,103 $ 14,672 $ 14,567 $ 410,642 $ 5,682 $ 5,341 Derivatives Designated as Hedging Instruments The Company uses derivative instruments to hedge its exposure to economic risks, including interest rate, liquidity, and credit risk. Certain hedging relationships are formally designated and qualify for hedge accounting under GAAP as fair value or cash flow hedges. Fair Value Hedges - Derivatives are designated as fair value hedges to limit the Company's exposure to changes in the fair value of assets or liabilities due to movements in interest rates. The Company entered into pay-fixed receive-floating interest rate swaps to manage its exposure to changes in fair value in certain fixed-rate assets. The gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in interest income. The table below presents the effect of the Company’s derivative financial instruments designated as hedging instruments on the consolidated statements of income for the periods indicated: Location and Amount of Gain or Loss Recognized in Income on Fair Value Hedging Relationships For the Three Months Ended June 30, For the Six Months Ended June 30, 2022 2021 2022 2021 (in thousands) Interest Income Other Income Interest Income Other Income Interest Income Other Income Interest Income Other Income Total amounts of income and expense line items presented in the consolidated statements of income in which the effects of fair value hedges are recorded $ (67) $ — $ (111) $ — $ (171) $ — $ (219) $ — Gain (loss) on fair value hedging relationships in subtopic 815-20: Interest contracts: Hedged items (963) — 578 — (2,516) — (1,055) — Derivative designated as hedging instruments 896 — (370) — 2,344 — 753 — As of June 30, 2022, the following amounts were recorded on the balance sheet related to cumulative basis adjustment for fair value hedges: Line Item in the Balance Sheet in Which the Hedged Item is Included Carrying Amount of the Hedged Assets Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Asset (in thousands) Loans $ 22,902 $ (1,537) Derivatives Not Designated as Hedging Instruments Interest Rate Swaps - The Company periodically enters into commercial loan interest rate swap agreements in order to provide commercial loan customers with the ability to convert from variable to fixed interest rates. These derivative contracts relate to transactions in which the Company enters into an interest rate swap with a customer, while simultaneously entering into an offsetting interest rate swap with an institutional counterparty. Credit Risk Participation Agreements -The Company enters into RPAs to manage the credit exposure on interest rate contracts associated with a syndicated loan. The Company may enter into protection purchased RPAs with institutional counterparties to decrease or increase its exposure to a borrower. Under the RPA, the Company will receive or make payment if a borrower defaults on the related interest rate contract. The notional amount of the RPAs reflects the Company’s pro-rata share of the derivative instrument. Interest Rate Forward Loan Sales Contracts & Interest Rate Lock Commitments - The Company enters into forward delivery contracts to sell residential mortgage loans at specific prices and dates in order to hedge the interest rate risk in its portfolio of mortgage loans held for sale and its residential mortgage interest rate lock commitments. The following table presents the net gains (losses) recognized on the consolidated statements of income related to the derivatives not designated as hedging instruments for the periods indicated: Location in the Consolidated Statements of Income For the Three Months Ended June 30, For the Six Months Ended June 30, (in thousands) 2022 2021 2022 2021 Interest rate swaps Other income $ 3 $ 1 $ 8 $ 35 RPAs Other income — 1 1 1 Interest rate lock commitments Loan revenue 163 — (218) — Interest rate forward loan sales contracts Loan revenue (339) — (28) — Total $ (173) $ 2 $ (237) $ 36 Offsetting of Derivatives The Company has entered into agreements with certain counterparty financial institutions, which include master netting agreements. However, the Company has elected to account for all derivatives with counterparty institutions on a gross basis. The Company manages the risk of default by its borrower counterparties through its normal loan underwriting and credit monitoring policies and procedures. The table below presents gross derivatives and the respective collateral received or pledged in the form of other financial instruments as of June 30, 2022 and December 31, 2021, which are generally marketable securities and/or cash. The collateral amounts in the table below are limited to the outstanding balances of the related asset or liability (after netting is applied); thus instances of over-collateralization are not shown. Further, the net amounts of derivative assets or liabilities can be reconciled to the tabular disclosure of fair value. The tabular disclosure of fair value provides the location that derivative assets and liabilities are presented on the consolidated balance sheets.

Regulatory Capital Requirements and Restrictions on Subsidiary Cash	Regulatory Capital Requirements and Restrictions on Subsidiary Cash Regulatory Capital and Reserve Requirement - The Company (on a consolidated basis) and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company's consolidated financial statements. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. As of June 30, 2022 and December 31, 2021, the Bank was not required to maintain reserve balances in cash on hand or on deposit with Federal Reserve Banks, and therefore the total amount held in reserve for each of these periods was zero dollars. A comparison of the Company's and the Bank's capital with the corresponding minimum regulatory requirements in effect as of June 30, 2022 and December 31, 2021, is presented below: Actual For Capital Adequacy Purposes With Capital Conservation Buffer (1) To Be Well Capitalized Under Prompt Corrective Action Provisions (dollars in thousands) Amount Ratio Amount Ratio Amount Ratio At June 30, 2022 Consolidated: Total capital/risk weighted assets $627,160 11.73% $561,461 10.50% N/A N/A Tier 1 capital/risk weighted assets 513,805 9.61 454,516 8.50 N/A N/A Common equity tier 1 capital/risk weighted assets 471,777 8.82 374,307 7.00 N/A N/A Tier 1 leverage capital/average assets 513,805 8.51 241,422 4.00 N/A N/A MidWest One Bank: Total capital/risk weighted assets $633,610 11.90% $559,205 10.50% $532,576 10.00% Tier 1 capital/risk weighted assets 585,255 10.99 452,690 8.50 426,061 8.00 Common equity tier 1 capital/risk weighted assets 585,255 10.99 372,803 7.00 346,175 6.50 Tier 1 leverage capital/average assets 585,255 9.70 241,389 4.00 301,736 5.00 At December 31, 2021 Consolidated: Total capital/risk weighted assets $615,060 13.09% $493,283 10.50% N/A N/A Tier 1 capital/risk weighted assets 508,687 10.83 399,324 8.50 N/A N/A Common equity tier 1 capital/risk weighted assets 466,747 9.94 328,855 7.00 N/A N/A Tier 1 leverage capital/average assets 508,687 8.67 234,745 4.00 N/A N/A MidWest One Bank: Total capital/risk weighted assets $584,348 12.46% $492,436 10.50% $468,987 10.00% Tier 1 capital/risk weighted assets 542,975 11.58 398,639 8.50 375,189 8.00 Common equity tier 1 capital/risk weighted assets 542,975 11.58 328,291 7.00 304,841 6.50 Tier 1 leverage capital/average assets 542,975 9.25 234,686 4.00 293,358 5.00 (1) Includes a capital conservation buffer of 2.50%.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Credit-related financial instruments - The Bank is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, commitments to sell loans, and standby letters of credit. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the balance sheets. The Bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. The following table summarizes the Bank’s commitments as of the dates indicated: June 30, 2022 December 31, 2021 (in thousands) Commitments to extend credit $ 1,117,754 $ 1,014,397 Commitments to sell loans 4,991 12,917 Standby letters of credit 18,419 16,342 Total $ 1,141,164 $ 1,043,656 The Bank’s exposure to credit loss in the event of nonperformance by the counterparty to the financial instrument for commitments to extend credit is represented by the contractual amount of those instruments. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Bank evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, is based on management’s credit evaluation of the party. Collateral held varies, but may include accounts receivable, crops, livestock, inventory, property and equipment, residential real estate and income-producing commercial properties. Commitments to sell loans are agreements to sell loans held for sale to third parties at an agreed upon price. Standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements and, generally, have terms of one year or less. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Bank holds collateral, which may include accounts receivable, inventory, property, equipment and income-producing properties, that support those commitments, if deemed necessary. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Bank would be required to fund the commitment. The maximum potential amount of future payments the Bank could be required to make is represented by the contractual amount shown in the summary above. If the commitment is funded, the Bank would be entitled to seek recovery from the customer. Liability for Off-Balance Sheet Credit Losses - The Company records a liability for off-balance sheet credit losses through a charge to credit loss expense (or a reversal of credit loss expense) on the Company's consolidated statements of income and other liabilities on the Company's consolidated balance sheets. At June 30, 2022, the liability for off-balance-sheet credit losses totaled $4.5 million, whereas the total amount of the liability as of December 31, 2021 was $4.0 million. The total amount recorded in credit loss expense (benefit) for the six-months ended June 30, 2022 was an expense of $0.5 million, while a credit loss benefit of $0.1 million was recorded for the six-months ended June 30, 2021. Litigation - In the normal course of business, the Company and its subsidiaries have been named, from time to time, as defendants in various legal actions. Certain of the actual or threatened legal actions may include claims for substantial compensatory and/or punitive damages or claims for indeterminate amounts of damages. Management, after consulting with legal counsel, is of the opinion that the ultimate liability, if any, resulting from these pending or threatened actions and proceedings will not have a material effect on the financial statements of the Company. Concentrations of credit risk - Substantially all of the Bank’s loans, commitments to extend credit and standby letters of credit have been granted to customers in the Bank’s market areas. Although the loan portfolio of the Bank is diversified, approximately 62% of the loans are real estate loans, excluding farmland, and approximately 8% are agriculturally related. The concentrations of credit by type of loan are set forth in Note 4. Loans Receivable and the Allowance for Credit Losses

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments and Fair Value Measurements	Fair Value of Financial Instruments and Fair Value Measurements Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: • Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. • Level 2 – Significant other observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. • Level 3 – Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. For additional information regarding the valuation methodologies used to measure the Company's assets recorded at fair value, and for estimating fair value for financial instruments not recorded at fair value, see Note 1. Nature of Business and Significant Accounting Policies and Note 20. Estimated Fair Value of Financial Instruments and Fair Value Measurements to the consolidated financial statements in the Company's 2021 Annual Report on Form 10-K, filed with the SEC on March 10, 2022. The Company uses fair value to measure certain assets and liabilities on a recurring basis, primarily available for sale debt securities, derivatives and mortgage servicing rights. For assets measured at the lower of cost or fair value, the fair value measurement criteria may or may not be met during a reporting period, and such measurements are therefore considered "nonrecurring" for purposes of disclosing the Company's fair value measurements. Fair value is used on a nonrecurring basis to adjust carrying values for collateral dependent individually analyzed loans and other real estate owned. Recurring Basis The following table summarizes assets and liabilities measured at fair value on a recurring basis as of the dates indicated, by level within the fair value hierarchy: Fair Value Measurement at June 30, 2022 Using (in thousands) Total Level 1 Level 2 Level 3 Assets: Available for sale debt securities: U.S. Government agencies and corporations $ 7,904 $ — $ 7,904 $ — State and political subdivisions 315,911 — 315,911 — Mortgage-backed securities 6,539 — 6,539 — Collateralized mortgage obligations 165,375 — 165,375 — Corporate debt securities 739,060 — 739,060 — Derivative assets 16,213 — 16,101 112 Mortgage servicing rights 12,864 — 12,864 — Liabilities: Derivative liabilities $ 14,567 $ — $ 14,567 $ — Fair Value Measurement at December 31, 2021 Using (in thousands) Total Level 1 Level 2 Level 3 Assets: Debt securities available for sale: U.S. Government agencies and corporations $ 266 $ — $ 266 $ — State and political subdivisions 765,742 — 765,742 — Mortgage-backed securities 100,626 — 100,626 — Collateralized mortgage obligations 768,899 — 768,899 — Corporate debt securities 652,577 — 652,577 — Derivative assets 6,106 — 5,776 330 Mortgage servicing rights 6,532 — 6,532 — Liabilities: Derivative liabilities $ 6,741 $ — $ 6,741 $ — There were no transfers of assets between Level 3 and other levels of the fair value hierarchy during the six months ended June 30, 2022 or the year ended December 31, 2021.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying interim condensed consolidated financial statements are prepared in accordance with GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X of the Securities Exchange Act of 1934. Accordingly, certain disclosures accompanying annual consolidated financial statements are omitted. In the opinion of management, all significant intercompany accounts and transactions have been eliminated and adjustments, consisting solely of normal recurring accruals and considered necessary for the fair presentation of financial statements for the interim periods, have been included. The current period's results of operations are not necessarily indicative of the results that ultimately may be achieved for the year. The interim condensed consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Form 10-K for the year ended December 31, 2021, filed with the SEC on March 10, 2022.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect: (1) the reported amounts of assets and liabilities, (2) the disclosure of contingent assets and liabilities at the date of the financial statements, and (3) the reported amounts of revenues and expenses during the reporting period. These estimates are based on information available to management at the time the estimates are made. Actual results could differ from those estimates. The results for the six months ended June 30, 2022 may not be indicative of results for the year ending December 31, 2022, or for any other period. All significant accounting policies followed in the preparation of the quarterly financial statements are disclosed in the Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on March 10, 2022, except for the policies related to held to maturity debt securities and acquired loans.
Held to Maturity Debt Securities and Acquired Loans	Held to Maturity Debt Securities - Certain debt securities that the Company has the positive intent and ability to hold to maturity are classified as held to maturity and recorded at amortized cost. A debt security is placed on nonaccrual status at the time any principal or interest payments become 90 days delinquent. Interest accrued but not received for a security placed on nonaccrual is reversed against interest income. The Company evaluates debt securities held to maturity for current expected credit losses. Held-to-maturity securities are evaluated on a quarterly basis using historical probability of default and loss given default information specific to the investment category. If this evaluation determines that credit losses exist, an allowance for credit loss is recorded and included in earnings as a component of credit loss expense. The Company's mortgage-backed securities and collateralized mortgage obligations are issued by U.S. government agencies and U.S. government-sponsored enterprises and are implicitly guaranteed by the U.S. government, and as such are excluded from the credit loss evaluation. Accrued interest receivable on held to maturity debt securities is recorded within 'Other Assets,' and is excluded from the estimate of credit losses. Acquired Loans - Acquired loans are separated into two categories based on the credit risk characteristics of the underlying borrowers as either PCD, for loans which have experienced more than insignificant credit deterioration since origination, or loans with no credit deterioration (non-PCD). At the date of acquisition, an ACL on PCD loans is determined and added to the amortized cost basis of the individual loans. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. The ACL on PCD loans is recorded in the acquisition accounting and no provision for credit losses is recognized at the acquisition date. Subsequent changes to the ACL are recorded through provision expense. For non-PCD loans, an ACL is established immediately after the acquisition through a charge to the provision for credit losses.
Segment Reporting	Segment Reporting The Company’s activities are considered to be one reportable segment for financial reporting purposes. The Company is engaged in the business of commercial and retail banking and trust and investment management services with operations throughout central and eastern Iowa, the Minneapolis/St. Paul metropolitan area of Minnesota, southwestern Wisconsin, Naples and Fort Myers, Florida, and Denver, Colorado. Substantially all income is derived from a diverse base of commercial, mortgage and retail lending activities, and investments.
Effect of New Financial Accounting Standards	Effect of New Financial Accounting Standards Accounting Guidance Pending Adoption at June 30, 2022 On March 12, 2020, the FASB issued ASU 2020-04, Reference Rate Reform (ASC 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . ASC 848 contains optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform. Certain optional expedients and exceptions for contract modifications and hedging relationships were amended in ASU 2021-01, Reference Rate Reform (Topic 848): Scope Refinement , issued on January 7, 2021. Entities may apply the provision as of the beginning of the reporting period when the election is made and are available until December 31, 2022. The adoption of ASU ASU 2020-04 is not expected to have a material impact on the Company’s consolidated financial statements. On March 31, 2022, the FASB issued ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. For creditors that have adopted the CECL accounting guidance within ASU 2016-13, the amendments eliminate the accounting guidance for TDRs within ASC 310-40, while also enhancing the disclosure requirements for certain loan refinancings and restructurings when a borrower is experiencing financial difficulty. In addition, public business entities must also disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of ASC 326-20. The amendments are effective for fiscal years beginning after December 15, 2022 and should be applied prospectively, with an option to apply a modified retrospective transition approach for the recognition and measurement of TDRs. The Company is currently evaluating the impact of ASU 2022-02.
Derivatives	Derivatives Designated as Hedging Instruments The Company uses derivative instruments to hedge its exposure to economic risks, including interest rate, liquidity, and credit risk. Certain hedging relationships are formally designated and qualify for hedge accounting under GAAP as fair value or cash flow hedges.
Fair Value Measurements	Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: • Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. • Level 2 – Significant other observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. • Level 3 – Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. For additional information regarding the valuation methodologies used to measure the Company's assets recorded at fair value, and for estimating fair value for financial instruments not recorded at fair value, see Note 1. Nature of Business and Significant Accounting Policies and Note 20. Estimated Fair Value of Financial Instruments and Fair Value Measurements to the consolidated financial statements in the Company's 2021 Annual Report on Form 10-K, filed with the SEC on March 10, 2022. The Company uses fair value to measure certain assets and liabilities on a recurring basis, primarily available for sale debt securities, derivatives and mortgage servicing rights.
