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, 2022, filed with the SEC on March 13, 2023. 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 three months ended March 31, 2023 may not be indicative of results for the year ending December 31, 2023, 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, 2022, filed with the SEC on March 13, 2023. 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 March 31, 2023 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. In addition, ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848 , deferred the sunset date of Topic 848 from December 31, 2022 to December 31, 2024, after which time entities will no longer be permitted to apply the relief in Topic 848. The adoption of ASU 2020-04 is not expected to have a material impact on the Company’s consolidated financial statements. Accounting Guidance Adopted at March 31, 2023 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 adoption of ASU 2022-02 was applied prospectively and did not have a material impact on the Company's consolidated financial statements.

Business Combination and Asset Acquisition [Abstract]
Business Combinations	Business Combinations On June 9, 2022, the Company acquired 100% of the equity of IOFB through a merger and acquired its wholly-owned subsidiaries FNBM and FNBF for cash consideration of $46.7 million. 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, FNBM and FNBF 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). 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. Bargain purchase gains are recorded net of deferred taxes and are treated as permanent differences, resulting in lower effective tax rate in the period recorded. The table below summarizes the amounts recognized as of the acquisition date for each major class of assets acquired and liabilities assumed.

There were no debt securities held to maturity classified as nonaccrual or past due as of March 31, 2023. 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. Proceeds and gross realized gains and losses on debt securities available for sale for the three months ended March 31, 2023 and 2022, were as follows: Three Months Ended (in thousands) March 31, 2023 March 31, 2022 Proceeds from sales of debt securities available for sale $ 218,667 $ — Gross realized gains from sales of debt securities available for sale — — Gross realized losses from sales of debt securities available for sale (13,170) — Net realized gain from sales of debt securities available for sale (1) $ (13,170) $ — (1) The difference in investment security gains, net reported herein as compared to the Consolidated Statements of Income is associated with the net realized gain from the call or maturity of debt securities of $0 for the three months ended March 31, 2023 and $40 thousand for the three months ended March 31, 2022.

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 for all loan types, except owner occupied residential real estate, which are moved to non-accrual at 120 days or more past due, 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. The following table presents the amortized cost basis of loans based on delinquency status: Age Analysis of Past-Due Financial Assets 90 Days or More Past Due And Accruing (in thousands) Current 30 - 59 Days Past Due 60 - 89 Days Past Due 90 Days or More Past Due Total March 31, 2023 Agricultural $ 105,506 $ 851 $ — $ 284 $ 106,641 $ — Commercial and industrial 1,078,687 627 378 822 1,080,514 — Commercial real estate: Construction and development 320,924 — — — 320,924 — Farmland 180,721 31 — 1,776 182,528 — Multifamily 255,065 — — — 255,065 — Commercial real estate-other 1,289,988 — 48 418 1,290,454 — Total commercial real estate 2,046,698 31 48 2,194 2,048,971 — Residential real estate: One- to four- family first liens 444,724 3,124 156 455 448,459 2 One- to four- family junior liens 161,357 120 30 896 162,403 — Total residential real estate 606,081 3,244 186 1,351 610,862 2 Consumer 72,235 125 10 7 72,377 — Total $ 3,909,207 $ 4,878 $ 622 $ 4,658 $ 3,919,365 $ 2 Age Analysis of Past-Due Financial Assets 90 Days or More Past Due And Accruing (in thousands) Current 30 - 59 Days Past Due 60 - 89 Days Past Due 90 Days or More Past Due Total December 31, 2022 Agricultural $ 114,922 $ 100 $ — $ 298 $ 115,320 $ — Commercial and industrial 1,052,406 922 111 1,723 1,055,162 — Commercial real estate: Construction and development 270,905 86 — — 270,991 — Farmland 182,115 729 — 1,069 183,913 — Multifamily 252,129 — — — 252,129 — Commercial real estate-other 1,266,874 5,574 45 492 1,272,985 — Total commercial real estate 1,972,023 6,389 45 1,561 1,980,018 — Residential real estate: One- to four- family first liens 446,066 3,177 954 1,013 451,210 565 One- to four- family junior liens 161,989 301 78 850 163,218 — Total residential real estate 608,055 3,478 1,032 1,863 614,428 565 Consumer 75,443 110 17 26 75,596 — Total $ 3,822,849 $ 10,999 $ 1,205 $ 5,471 $ 3,840,524 $ 565 The following table presents the amortized cost basis of loans on non-accrual status, amortized cost basis of loans on non-accrual status with no allowance for credit losses recorded, and loans past due 90 days or more and still accruing by class of loan: Nonaccrual Nonaccrual with no Allowance for Credit Losses 90 Days or More Past Due And Accruing (in thousands) March 31, 2023 December 31, 2022 March 31, 2023 December 31, 2022 March 31, 2023 December 31, 2022 Agricultural $ 307 $ 377 $ 224 $ 281 $ — $ — Commercial and industrial 2,192 2,728 483 1,049 — — Commercial real estate: Construction and development — — — — — — Farmland 1,931 2,278 1,776 1,997 — — Multifamily — — — — — — Commercial real estate-other 6,191 6,397 4,121 5,647 — — Total commercial real estate 8,122 8,675 5,897 7,644 — — Residential real estate: One- to four- family first liens 2,536 2,275 910 928 2 565 One- to four- family junior liens 1,258 1,165 — — — — Total residential real estate 3,794 3,440 910 928 2 565 Consumer 25 36 — — — — Total $ 14,440 $ 15,256 $ 7,514 $ 9,902 $ 2 $ 565 The interest income recognized on loans that were on nonaccrual for the three months ended March 31, 2023 and March 31, 2022 was $56 thousand and $70 thousand, respectively. 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, commercial real estate and non-owner occupied residential 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 owner occupied 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 following table sets forth the amortized cost basis of loans by class of receivable by credit quality indicator, and vintage, in addition to the current period gross write-offs by class of receivable and vintage, based on the most recent analysis performed, as of March 31, 2023. As of March 31, 2023, there were no 'loss' rated credits.

In addition, management utilized qualitative factors to adjust the calculated ACL as appropriate. Qualitative factors are based on management’s judgment of company, market, industry or business specific data, changes in underlying loan composition of specific portfolios, trends relating to credit quality, delinquency, non-performing and adversely rated loans, and reasonable and supportable forecasts of economic conditions. The increase in the ACL between March 31, 2023 and December 31, 2022 is primarily driven by reserves taken to support loan growth. Net loan charge-offs were $0.3 million for the three-months ended March 31, 2023 as compared to net loan charge-offs of $2.2 million for the three-months ended March 31, 2022.

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. Cash Flow Hedges - Derivatives are designated as cash flow hedges in order to minimize the variability in cash flows of earning assets or forecasted transactions caused by movement in interest rates. In March 2023, the Company entered into pay-fixed receive-variable interest rate swaps with a cumulative notional amount of $50.0 million to hedge against adverse fluctuations in interest rates by reducing exposure to variability in cash flows relating to interest payments on the Company's variable rate debt. The interest rate swaps were designated as a cash flow hedge. The gain or loss on the derivative was recorded in accumulated other comprehensive income and subsequently reclassified into interest expense, as applicable, in the same period(s) during which the hedged transaction affects earnings. During 2023, the Company estimates that an additional $561 thousand of income will be reclassified into interest expense.

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 Company’s obligation under the junior subordinated notes and other relevant trust agreements, in aggregate, constitutes a full and unconditional guarantee by the Company of each trust’s obligations under the trust preferred securities issued by each trust. The Company has the right to defer payment of interest on the junior subordinated notes and, therefore, distributions on the trust preferred securities, for up to five years, but not beyond the stated maturity date in the table above. During any such deferral period the Company may not pay cash dividends on its stock and generally may not repurchase its stock.

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 March 31, 2023 and December 31, 2022, 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 March 31, 2023 and December 31, 2022, 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 March 31, 2023 Consolidated: Total capital/risk weighted assets $654,151 12.31% $557,940 10.50% N/A N/A Tier 1 capital/risk weighted assets 540,980 10.18 451,666 8.50 N/A N/A Common equity tier 1 capital/risk weighted assets 498,820 9.39 371,960 7.00 N/A N/A Tier 1 leverage capital/average assets 540,980 8.30 260,813 4.00 N/A N/A MidWest One Bank: Total capital/risk weighted assets $653,184 12.31% $557,101 10.50% $530,573 10.00% Tier 1 capital/risk weighted assets 605,014 11.40 450,987 8.50 424,458 8.00 Common equity tier 1 capital/risk weighted assets 605,014 11.40 371,401 7.00 344,872 6.50 Tier 1 leverage capital/average assets 605,014 9.28 260,685 4.00 325,857 5.00 At December 31, 2022 Consolidated: Total capital/risk weighted assets $653,380 12.07% $568,452 10.50% N/A N/A Tier 1 capital/risk weighted assets 544,300 10.05 460,175 8.50 N/A N/A Common equity tier 1 capital/risk weighted assets 502,184 9.28 378,968 7.00 N/A N/A Tier 1 leverage capital/average assets 544,300 8.35 260,891 4.00 N/A N/A MidWest One Bank: Total capital/risk weighted assets $654,297 12.10% $567,684 10.50% $540,652 10.00% Tier 1 capital/risk weighted assets 610,217 11.29 459,554 8.50 432,522 8.00 Common equity tier 1 capital/risk weighted assets 610,217 11.29 378,456 7.00 351,424 6.50 Tier 1 leverage capital/average assets 610,217 9.36 260,776 4.00 325,970 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: March 31, 2023 December 31, 2022 (in thousands) Commitments to extend credit $ 1,205,902 $ 1,190,607 Commitments to sell loans 2,553 612 Standby letters of credit 17,374 18,398 Total $ 1,225,829 $ 1,209,617 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 March 31, 2023 and December 31, 2022, the liability for off-balance-sheet credit losses totaled $4.8 million. For the three-months ended March 31, 2023, no credit loss expense was recorded, while a credit loss expense of $0.3 million was recorded for the three-months ended March 31, 2022. 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 63% of the loans are real estate loans, excluding farmland, and approximately 7% 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 of Financial Instrum

Fair Value of Financial Instruments and Fair Value Measurements	3 Months Ended
	Mar. 31, 2023
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 2022 Annual Report on Form 10-K, filed with the SEC on March 13, 2023. 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 March 31, 2023 Using (in thousands) Total Level 1 Level 2 Level 3 Assets: Available for sale debt securities: State and political subdivisions $ 184,581 $ — $ 184,581 $ — Mortgage-backed securities 5,679 — 5,679 — Collateralized loan obligations 54,074 — 54,074 — Collateralized mortgage obligations 144,666 — 144,666 — Corporate debt securities 565,074 — 565,074 — Derivative assets 18,513 — 18,412 101 Mortgage servicing rights 13,736 — 13,736 — Liabilities: Derivative liabilities $ 16,302 $ — $ 16,302 $ — Fair Value Measurement at December 31, 2022 Using (in thousands) Total Level 1 Level 2 Level 3 Assets: Debt securities available for sale: U.S. Government agencies and corporations $ 7,345 $ — $ 7,345 $ — State and political subdivisions 285,356 — 285,356 — Mortgage-backed securities 5,944 — 5,944 — Collateralized mortgage obligations 147,193 — 147,193 — Corporate debt securities 707,709 — 707,709 — Derivative assets 23,655 — 23,648 7 Mortgage servicing rights 13,421 — 13,421 — Liabilities: Derivative liabilities $ 21,087 $ — $ 21,087 $ — There were no transfers of assets between Level 3 and other levels of the fair value hierarchy during the three months ended March 31, 2023 or the year ended December 31, 2022.

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, 2022, filed with the SEC on March 13, 2023.
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 three months ended March 31, 2023 may not be indicative of results for the year ending December 31, 2023, or for any other period.
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 March 31, 2023 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. In addition, ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848 , deferred the sunset date of Topic 848 from December 31, 2022 to December 31, 2024, after which time entities will no longer be permitted to apply the relief in Topic 848. The adoption of ASU 2020-04 is not expected to have a material impact on the Company’s consolidated financial statements. Accounting Guidance Adopted at March 31, 2023 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 adoption of ASU 2022-02 was applied prospectively and did not have a material impact on the Company's consolidated financial statements.
Derivatives Designated as Hedging Instruments	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. Cash Flow Hedges - Derivatives are designated as cash flow hedges in order to minimize the variability in cash flows of earning assets or forecasted transactions caused by movement in interest rates. In March 2023, the Company entered into pay-fixed receive-variable interest rate swaps with a cumulative notional amount of $50.0 million to hedge against adverse fluctuations in interest rates by reducing exposure to variability in cash flows relating to interest payments on the Company's variable rate debt. The interest rate swaps were designated as a cash flow hedge. The gain or loss on the derivative was recorded in accumulated other comprehensive income and subsequently reclassified into interest expense, as applicable, in the same period(s) during which the hedged transaction affects earnings. During 2023, the Company estimates that an additional $561 thousand of income will be reclassified into interest expense. The table below presents the effect of cash flow hedge accounting on AOCI for the three months ended March 31, 2023 and 2022 Amount of Gain (Loss) Recognized in AOCI on Derivative Location of Gain (Loss) Reclassified from AOCI into Income Amount of Gain (Loss) Reclassified from AOCI into Income Three Months Ended March 31, Three Months Ended March 31, (in thousands) 2023 2022 2023 2022 Interest rate swaps $ 138 $ — Interest Expense $ — $ —
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 2022 Annual Report on Form 10-K, filed with the SEC on March 13, 2023. 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.
