Organization, Consolidation and Presentation of Financial Statements [Abstract]
GENERAL	GENERAL Financial Statement Preparation The Consolidated Condensed Balance Sheet of the Corporation as of December 31, 2021, has been derived from the audited consolidated balance sheet of the Corporation as of that date. Certain information and note disclosures normally included in the Corporation’s annual financial statements, prepared in accordance with accounting principles generally accepted in the United States of America, have been condensed or omitted. These consolidated condensed financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2021 filed with the Securities and Exchange Commission. The results of operations for the three and nine months ended September 30, 2022, are not necessarily indicative of the results to be expected for the year. Reclassifications have been made to prior financial statements to conform to the current financial statement presentation. These reclassifications had no effect on net income. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for credit losses and fair value of financial instruments. Significant Accounting Policies The significant accounting policies followed by the Corporation and its wholly-owned subsidiaries for interim financial reporting are consistent with the accounting policies followed for annual financial reporting. All adjustments, which are of a normal recurring nature and are in the opinion of management necessary for a fair statement of the results for the periods reported, have been included in the accompanying Consolidated Condensed Financial Statements. The Corporation did not adopt any new accounting pronouncements during the first nine months of 2022. The Corporation continually monitors potential accounting pronouncements and the following pronouncements have been deemed to have the most applicability to the Corporation's financial statements: New Accounting Pronouncements Not Yet Adopted FASB Accounting Standards Updates - No. 2020-04 - Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting Summary - The FASB issued ASU No. 2020-04 to provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. LIBOR and other interbank offered rates are widely used benchmarks or reference rates in the United States and globally. Trillions of dollars in loans, derivatives, and other financial contracts reference LIBOR, the benchmark interest rate banks use to make short-term loans to each other. With global capital markets expected to move away from LIBOR and other interbank offered rates and move toward rates that are more observable or transaction based and less susceptible to manipulation, the FASB launched a broad project in late 2018 to address potential accounting challenges expected to arise from the transition. The new guidance provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. The ASU is intended to help stakeholders during the global market-wide reference rate transition period. Entities may apply this ASU as of the beginning of an interim period that includes the March 12, 2020 issuance date of the ASU, through December 31, 2022. The Corporation expects to adopt the practical expedients included in the ASU prior to December 31, 2022. The Corporation is implementing a transition plan to identify and modify its loans and other financial instruments with attributes that are either directly or indirectly influenced by LIBOR. The Corporation is assessing ASU 2020-04 and its impact on the Corporation's transition away from LIBOR for its loans and other financial instruments. FASB Accounting Standards Updates - No. 2021-01 - Reference Rate Reform (Topic 848): Scope Summary - The FASB has published ASU 2021-01, Reference Rate Reform. ASU 2021-01 clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The ASU also amends the expedients and exceptions in Topic 848 to capture the incremental consequences of the scope clarification and to tailor the existing guidance to derivative instruments affected by the discounting transition. An entity may elect to apply the amendments in this Update on a full retrospective basis as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or on a prospective basis to new modifications from any date within an interim period that includes or is subsequent to the date of the issuance of a final Update, up to the date that financial statements are available to be issued. If an entity elects to apply any of the amendments in this Update for an eligible hedging relationship, any adjustments as a result of those elections must be reflected as of the date the entity applies the election. The amendments in this Update do not apply to contract modifications made after December 31, 2022, new hedging relationships entered into after December 31, 2022, and existing hedging relationships evaluated for effectiveness in periods after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that apply certain optional expedients in which the accounting effects are recorded through the end of the hedging relationship (including periods after December 31, 2022). The Corporation expects to adopt the practical expedients included in the ASU prior to December 31, 2022. The Corporation is assessing ASU 2021-01 and its impact on the Corporation's transition away from LIBOR for its loans and other financial instruments. FASB Accounting Standards Updates - No. 2021-08 - Business Combinations (Topic 805) - Accounting for Contract Assets and Contract Liabilities from Contracts with Customers Summary - The FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers , that addresses diversity in practice related to the accounting for revenue contracts with customers acquired in a business combination. Under current GAAP, an acquirer generally recognizes assets acquired and liabilities assumed in a business combination, including contract assets and contract liabilities arising from revenue contracts with customers and other similar contracts that are accounted for in accordance with Topic 606 , Revenue from Contracts with Customers , at fair value on the acquisition date. The FASB indicates that some stakeholders indicated that it is unclear how an acquirer should evaluate whether to recognize a contract liability from a revenue contract with a customer acquired in a business combination after Topic 606 is adopted. Furthermore, it was identified that under current practice, the timing of payment (payment terms) of a revenue contract may subsequently affect the post-acquisition revenue recognized by the acquirer. To address this, the ASU requires entities to apply Topic 606 to recognize and measure contract assets and contract liabilities in a business combination. Finally, the amendments in the ASU improve comparability after the business combination by providing consistent recognition and measurement guidance for revenue contracts with customers acquired in a business combination and revenue contracts with customers not acquired in a business combination. For public business entities, the amendments are effective for fiscal years beginning after December 31, 2022, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 31, 2023, including interim periods within those fiscal years. The amendments in this Update should be applied prospectively to business combinations occurring on or after the effective date of the amendments. Early adoption of the amendments is permitted, including adoption in an interim period. An entity that early adopts in an interim period should apply the amendments (1) retrospectively to all business combinations for which the acquisition date occurs on or after the beginning of the fiscal year that includes the interim period or early application, and (2) prospectively to all business combinations that occur on or after the date of initial application. The Corporation is reviewing the terms of this guidance, but adoption of the standard is not expected to have a significant impact on the Corporation's financial statements or disclosures. FASB Accounting Standards Updates - Accounting Standards Update No. 2022-02 - Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures Summary - The FASB issued ASU No. 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings ("TDRs") and Vintage Disclosures , which is intended to improve the usefulness of information provided to investors about certain loan refinancings, restructurings, and writeoffs. The amendments in the new ASU eliminate the accounting guidance for TDRs by creditors that have adopted CECL while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors made to borrowers experiencing financial difficulty. The amendments also require that a public business entity disclose current-period gross writeoffs by year of origination for financing receivables and net investment in leases. Since the Corporation adopted CECL on January 1, 2021, the amendments in ASU 2022-02 are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Corporation is assessing ASU 2022-02 and its impact on the Corporation's disclosures. The Corporation expects to adopt this ASU in the first quarter of 2023.

Business Combination and Asset Acquisition [Abstract]
ACQUISITIONS	ACQUISITIONS Level One Bancorp, Inc. On April 1, 2022, the Corporation acquired 100 percent of Level One Bancorp, Inc. ("Level One"). Level One, a Michigan corporation, merged with and into the Corporation (the "Merger"), whereupon the separate corporate existence of Level One ceased and the Corporation survived. Immediately following the Merger, Level One's wholly owned subsidiary, Level One Bank, merged with and into the Bank, with the Bank as the surviving bank. Level One was headquartered in Farmington Hills, Michigan and had 17 banking centers serving the Michigan market. Pursuant to the merger agreement, each common shareholder of Level One received, for each outstanding share of Level One common stock, (a) a 0.7167 share (the "Exchange Ratio") of the Corporation's common stock, in a tax-free exchange, and (b) a cash payment of $10.17. Fractional shares of the Corporation's common stock were not issued in respect of fractional interests arising from the Exchange Ratio but were paid in cash pursuant to the merger agreement. The Corporation issued 5.6 million shares of the Corporation's common stock and paid $79.3 million in cash, in exchange for all outstanding shares of Level One common stock. Additionally, each outstanding share of 7.5 percent non-cumulative perpetual preferred stock, Series B, of Level One was exchanged for one share of a newly created 7.5 percent non-cumulative perpetual preferred stock, Series A, of First Merchants with a liquidation preference of $2,500 per share. As a result, the Corporation issued 10,000 shares of Series A preferred stock at the acquisition date. Likewise, each outstanding Level One depositary share representing a 1/100th interest in a share of the Level One preferred stock was converted into a depositary share of the Corporation representing a 1/100th interest in a share of its newly issued preferred stock (Nasdaq: FRMEP). The Corporation engaged in this transaction with the expectation that it would be accretive to income and add to the existing market area in Michigan that has a demographic profile consistent with many of the current Midwest markets served by the Bank. Goodwill resulted from this transaction due to the expected synergies and economies of scale. Under the acquisition method of accounting, the total purchase price is allocated to net tangible and intangible assets based on their current estimated fair values on the date of the acquisition. Based on preliminary valuations of the fair value of tangible and intangible assets acquired and liabilities assumed, which are based on assumptions that are subject to change based on the timing of the transaction, the purchase price for the Level One acquisition is detailed in the following table. If, prior to the end of the one-year measurement period for finalizing the purchase price allocation, information becomes available about facts and circumstances that existed as of the acquisition date, which would indicate adjustments are required to the purchase price allocation, such adjustments will be included in the purchase price allocation retrospectively. Fair Value Cash and due from banks $ 217,104 Investment securities 370,658 Loans held for sale 7,951 Loans 1,626,857 Allowance for credit losses - loans (16,599) Premises and equipment 11,848 Federal Home Loan Bank stock 11,688 Interest receivable 7,188 Cash surrender value of life insurance 30,143 Tax asset, deferred and receivable 16,223 Other assets 41,690 Deposits (1,930,790) Securities sold under repurchase agreements (1,521) Federal Home Loan Bank advances (160,043) Subordinated debentures (32,631) Interest payable (1,065) Other liabilities (42,813) Net tangible assets acquired 155,888 Other intangibles 18,642 Goodwill 167,183 Purchase price $ 341,713 The Corporation performed an evaluation of the loan portfolio in which there were loans that, at acquisition, had more than an insignificant amount of credit quality deterioration and were classified as purchased credit deteriorated ("PCD"). Details of the PCD loans are included in NOTE 4. LOANS AND ALLOWANCE of these Notes to Consolidated Condensed Financial Statements. Of the total purchase price, $18.6 million has been allocated to other intangible assets. Approximately $17.2 million was allocated to a core deposit intangible, which will be amortized over its estimated life of 10 years. Approximately $1.4 million was allocated to a non-compete intangible, which will be amortized over its estimated life of 2 years. The remaining purchase price has been allocated to goodwill, which is not deductible for tax purposes. Hoosier Trust Company On April 1, 2021, the Bank acquired 100 percent of Hoosier Trust Company ("Hoosier") through a merger of Hoosier with and into the Bank. The consideration paid to shareholders of Hoosier at closing was $3,225,000 in cash. Prior to the acquisition, Hoosier was an Indiana corporate trust company, headquartered in Indianapolis, Indiana, with approximately $290 million in assets under management. Hoosier’s sole office is now being operated by the Bank as a limited service trust office. Under the acquisition method of accounting, the total purchase price is allocated to net tangible and intangible assets based on their current estimated fair value on the date of the acquisition. Based on the fair value of tangible and intangible assets acquired and liabilities assumed, which are based on assumptions that are subject to change based on the timing of the transaction, the purchase price for the Hoosier acquisition is detailed in the following table. Fair Value Cash and cash equivalents $ 292 Other assets 35 Other liabilities (816) Net tangible assets acquired (489) Customer relationship intangible 2,247 Goodwill 1,467 Purchase price $ 3,225 Pro Forma Financial Information The results of operations of Level One have been included in the Corporation's consolidated financial statements since the acquisition date. The following schedule includes pro forma results for the three and nine months ended September 30, 2022 and the annual period ended December 31, 2021 as if the Level One acquisition occurred as of the beginning of the periods presented. Pro forma financial information of the Hoosier acquisition is not included in the table below as it is deemed immaterial. Three Months Ended Nine Months Ended Total revenue (net interest income plus other income) $ 169,923 $ 476,074 Net income $ 63,752 $ 148,280 Net income available to common stockholders $ 63,283 $ 146,873 Earnings per common share: Basic $ 1.08 $ 2.49 Diluted $ 1.08 $ 2.48 2021 Total revenue (net interest income plus other income) $ 621,946 Net income $ 237,031 Net income available to common stockholders $ 235,156 Earnings per common share: Basic $ 3.96 Diluted $ 3.95 The pro forma information includes adjustments for interest income on loans and investment securities, interest expense on deposits and borrowings, premises expense for the banking centers acquired and amortization of intangibles arising from the transaction and the related income tax effects. The pro forma information for the three months ended September 30, 2022 includes operating revenue of $18.3 million from Level One, and $2.6 million, net of tax, of acquisition-related expenses. For the nine months ended September 30, 2022, the pro forma includes operating revenue of $38.7 million from Level One since the date of acquisition. Additionally, $12.2 million, net of tax, of acquisition-related expenses were included in the nine months ended September 30, 2022 proforma information. The pro forma information for the year ended December 31, 2021 includes operating results from Level One as if the acquisition occurred at the beginning of the year. The pro forma information is presented for information purposes only and is not indicative of the results of operations that actually would have been achieved had the acquisition been consummated as of that time, nor is it intended to be a projection of future results.

The total amount of accrued interest is excluded from the amortized cost of available for sale and held to maturity securities presented above. In determining the allowance for credit losses on investment securities available for sale that are in an unrealized loss position, the Corporation first assesses whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through the income statement. For investment securities available for sale that do not meet the aforementioned criteria, the Corporation evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, the Corporation considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Unrealized losses that have not been recorded through an allowance for credit losses is recognized in other comprehensive income. Adjustments to the allowance are reported in the income statement as a component of the provision for credit loss. The Corporation has made the accounting policy election to exclude accrued interest receivable on investment securities available for sale from the estimate of credit losses. Investment securities available for sale are charged off against the allowance or, in the absence of any allowance, written down through the income statement when deemed uncollectible or when either of the aforementioned criteria regarding intent or requirement to sell is met. The Corporation did not record an allowance for credit losses on its investment securities available for sale as the unrealized losses were attributable to changes in interest rates, not credit quality. The allowance for credit losses on investment securities held to maturity is a contra asset-valuation account that is deducted from the amortized cost basis of investment securities held to maturity to present the net amount expected to be collected. Investment securities held to maturity are charged off against the allowance when deemed uncollectible. Adjustments to the allowance are reported in the income statement as a component of the provision for credit loss. The Corporation measures expected credit losses on investment securities held to maturity on a collective basis by major security type with each type sharing similar risk characteristics, and considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. The Corporation has made the accounting policy election to exclude accrued interest receivable on investment securities held to maturity from the estimate of credit losses. With regard to U.S. Government-sponsored agency and mortgage-backed securities, all these securities are issued by a U.S. government-sponsored entity and have an implicit or explicit government guarantee; therefore, no allowance for credit losses has been recorded for these securities. With regard to securities issued by states and municipalities and other investment securities held to maturity, management considers (1) issuer bond ratings, (2) historical loss rates for given bond ratings, (3) the financial condition of the issuer, and (4) whether issuers continue to make timely principal and interest payments under the contractual terms of the securities. Historical loss rates associated with securities having similar grades as those in the Corporation's portfolio have been insignificant. Furthermore, as of September 30, 2022, there were no past due principal and interest payments associated with these securities. At CECL adoption, an allowance for credit losses of $245,000 was recorded on the state and municipal securities classified as held to maturity based on applying the long-term historical credit loss rate, as published by Moody’s, for similarly rated securities. The balance of the allowance for credit losses remained unchanged at $245,000 as of September 30, 2022. On a quarterly basis, the Corporation monitors the credit quality of investment securities held to maturity through the use of credit ratings. The following table summarizes the amortized cost of investment securities held to maturity at September 30, 2022, aggregated by credit quality indicator.

As a result, the Corporation expects to recover the amortized cost basis over the term of the securities. The Corporation does not intend to sell the investments and it is not more likely than not that the Corporation will be required to sell the investments before recovery of their amortized cost basis, which may be maturity. Certain investment securities available for sale are reported in the financial statements at an amount less than their historical cost as indicated in the table below. September 30, 2022 December 31, 2021 Investments available for sale reported at less than historical cost: Historical cost $ 2,351,925 $ 658,858 Fair value 1,959,311 645,218 Gross unrealized losses $ 392,614 $ 13,640 Percent of the Corporation's investments available for sale 98.8 % 27.5 % In determining the fair value of the investment securities portfolio, the Corporation utilizes a third party for portfolio accounting services, including market value input, for those securities classified as Level 1 and Level 2 in the fair value hierarchy. The Corporation has obtained an understanding of what inputs are being used by the vendor in pricing the portfolio and how the vendor classified these securities based upon these inputs. From these discussions, the Corporation’s management is comfortable that the classifications are proper. The Corporation has gained trust in the data for two reasons: (a) independent spot testing of the data is conducted by the Corporation through obtaining market quotes from various brokers on a periodic basis; and (b) actual gains or loss resulting from the sale of certain securities has proven the data to be accurate over time. Fair value of securities classified as Level 3 in the valuation hierarchy was determined using a discounted cash flow model that incorporated market estimates of interest rates and volatility in markets that have not been active. The amortized cost and fair value of investment securities available for sale and held to maturity at September 30, 2022 and December 31, 2021, by contractual maturity are shown below. Expected maturities will differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. Securities not due at a single maturity are shown separately.

At the time the accrual is discontinued, all unpaid accrued interest is reversed against earnings. Interest income accrued in prior years, if any, is charged to the allowance for credit losses. Payments subsequently received on non-accrual loans are applied to principal. A loan is returned to accrual status when principal and interest are no longer past due and collectability is probable, typically after a minimum of six consecutive months of performance. The following table summarizes the Corporation’s non-accrual loans by loan class for the periods indicated: September 30, 2022 December 31, 2021 Non-Accrual Loans Non-Accrual Loans with no Allowance for Credit Losses Non-Accrual Loans Non-Accrual Loans with no Allowance for Credit Losses Commercial and industrial loans $ 2,945 $ 1,354 $ 7,598 $ 263 Agricultural land, production and other loans to farmers 57 — 631 524 Real estate loans: Construction — — 685 — Commercial real estate, non-owner occupied 20,189 288 23,029 6,133 Commercial real estate, owner occupied 4,997 3,471 411 — Residential 10,703 722 9,153 2,160 Home equity 4,607 — 1,552 — Individuals' loans for household and other personal expenditures 10 — 3 — Loans $ 43,508 $ 5,835 $ 43,062 $ 9,080 There was no interest income recognized on non-accrual loans for the three and nine months ended September 30, 2022 or 2021. Determining fair value for collateral dependent loans requires obtaining a current independent appraisal of the collateral and applying a discount factor, which includes selling costs if applicable, to the value. The fair value of real estate is generally based on appraisals by qualified licensed appraisers. The appraisers typically determine the value of the real estate by utilizing an income or market valuation approach. If an appraisal is not available, the fair value may be determined by using a cash flow analysis. Fair value on other collateral such as business assets is typically ascertained by assessing, either singularly or some combination of, asset appraisals, accounts receivable aging reports, inventory listings and or customer financial statements. Both appraised values and values based on borrower’s financial information are discounted as considered appropriate based on age and quality of the information and current market conditions. The tables below present the amortized cost basis of collateral dependent loans by loan class and their respective collateral type, which are individually evaluated to determine expected credit losses. The increase in collateral dependent loans of $46.2 million, mostly due to the commercial and industrial loan class, is primarily related to loans from the acquisition of Level One.

A concession is deemed to be granted when, as a result of the restructuring, the Corporation does not expect to collect all original amounts due, including interest accrued at the original contract rate. If the payment of principal at original maturity is primarily dependent on the value of collateral, the current value of the collateral is considered in determining whether the principal will be repaid. The following tables summarize troubled debt restructures in the Corporation's loan portfolio that occurred during the three and nine months ended September 30, 2022 and 2021. There were no troubled debt restructures that occurred in the three months ended September 30, 2022.

Loans secured by commercial real estate, non owner occupied made up 99.9 percent and 92.3 percent, respectively, of the post-modification balances that occurred during the three and nine months ended September 30, 2021. The following tables summarize troubled debt restructures that occurred during the twelve month ended September 30, 2021, that subsequently defaulted during the period indicated and remained in default at period end. For purposes of this schedule, a loan is considered in default if it is 30-days or more past due. There were no loans that subsequently defaulted during the three and nine months ended September 30, 2022.

Commercial troubled debt restructures that are not individually evaluated for a specific reserve are included in the calculation of allowance for credit losses through the loan segment loss analysis. For all consumer loan modifications, an evaluation to identify if a troubled debt restructure has occurred is performed prior to making the modification. Any subsequent deterioration is addressed through the charge-off process or through a specific reserve allocation included in the allowance for credit losses. Consumer troubled debt restructures that are not individually evaluated for a specific reserve are included in the calculation of the allowance for credit losses through the loan segment loss analysis. Consumer loans secured by residential real estate properties for which formal foreclosure proceedings are in process totaled $2.0 million and $3.9 million at September 30, 2022 and 2021. Purchased Credit Deteriorated Loans The Corporation acquired Level One on April 1, 2022 and performed an evaluation of the loan portfolio in which there were loans that, at acquisition, had more than an insignificant amount of credit quality deterioration. The carrying amount of those loans is shown in the table below: Level One Purchase price of loans at acquisition $ 41,347 CECL Day 1 PCD ACL 16,599 Par value of acquired loans at acquisition $ 57,946 Allowance for Credit Losses on Loans The Allowance for Credit Losses on Loans ("ACL - Loans") is a valuation account that is deducted from the amortized cost basis of loans to present the net amount expected to be collected on loans over the contractual term. The ACL - Loans is adjusted by the provision for credit losses, which is reported in earnings, and reduced by charge offs for loans, net of recoveries. Provision for credit losses on loans reflects the totality of actions taken on all loans for a particular period including any necessary increases or decreases in the allowance related to changes in credit loss expectations associated with specific loans or pools of loans. Loans are charged off against the allowance when the uncollectibility of the loan is confirmed. Expected recoveries do not exceed the aggregate of amounts previously charged off and expected to be charged off. The allowance represents the Corporation’s best estimate of current expected credit losses on loans using relevant available information, from internal and external sources, related to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. The current expected credit loss ("CECL") calculation is performed and evaluated quarterly and losses are estimated over the expected life of the loan. The level of the allowance for credit losses is believed to be adequate to absorb all expected future losses inherent in the loan portfolio at the measurement date. In calculating the allowance for credit losses, the loan portfolio was pooled into ten loan segments with similar risk characteristics. Common characteristics include the type or purpose of the loan, underlying collateral and historical/expected credit loss patterns. In developing the loan segments, the Corporation analyzed the degree of correlation in how loans within each portfolio respond when subjected to varying economic conditions and scenarios as well as other portfolio stress factors. The expected credit losses are measured over the life of each loan segment utilizing the Probability of Default / Loss Given Default methodology combined with economic forecast models to estimate the current expected credit loss inherent in the loan portfolio. This approach is also leveraged to estimate the expected credit losses associated with unfunded loan commitments incorporating expected utilization rates. The Corporation sub-segmented certain commercial portfolios by risk level and certain consumer portfolios by delinquency status where appropriate. The Corporation utilized a four-quarter reasonable and supportable economic forecast period followed by a six-quarter, straight-line reversion period to the historical macroeconomic mean for the remaining life of the loans. Econometric modeling was performed using historical default rates and a selection of economic forecast scenarios published by Moody’s to develop a range of estimated credit losses for which to determine the best credit loss estimate within. Macroeconomic factors utilized in the modeling process include the national unemployment rate, BBB US corporate index, CRE price index and the home price index. The Corporation qualitatively adjusts model results for risk factors that are not inherently considered in the quantitative modeling process, but are nonetheless relevant in assessing the expected credit losses within the loan portfolio. These adjustments may increase or decrease the estimate of expected credit losses based upon the assessed level of risk for each qualitative factor. The various risks that may be considered in making qualitative adjustments include, among other things, the impact of (i) changes in the nature and volume of the loan portfolio, (ii) changes in the existence, growth and effect of any concentrations in credit, (iii) changes in lending policies and procedures, including changes in underwriting standards and practices for collections, write-offs, and recoveries, (iv) changes in the quality of the credit review function, (v) changes in the experience, ability and depth of lending management and staff, and (vi) other environmental factors of a borrower such as regulatory, legal and technological considerations, as well as competition. In some cases, management may determine that an individual loan exhibits unique risk characteristics which differentiate the loan from other loans within the loan segments. In such cases, the loans are evaluated for expected credit losses on an individual basis and excluded from the collective evaluation. Specific reserve allocations of the allowance for credit losses are determined by analyzing the borrower’s ability to repay amounts owed, collateral deficiencies, the relative risk grade of the loan and economic conditions affecting the borrower’s industry, among other things. A loan is considered to be collateral dependent when, based upon management's assessment, the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. In such cases, expected credit losses are based on the fair value of the collateral at the measurement date, adjusted for estimated selling costs if satisfaction of the loan depends on the sale of the collateral. The fair value of collateral supporting collateral dependent loans is evaluated on a quarterly basis. No allowance for credit losses has been recognized for PPP loans as such loans are fully guaranteed by the Small Business Administration ("SBA"). The risk characteristics of the Corporation’s portfolio segments are as follows: Commercial Commercial lending is primarily based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not be as expected and the collateral securing these loans may fluctuate in value. Most commercial loans are secured by the tangible assets being financed such as equipment or real estate or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee. Other loans may be unsecured, secured but under-collateralized or otherwise made on the basis of the enterprise value of an organization. In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its customers. Commercial real estate Commercial real estate loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts and the repayment of these loans is generally dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. The Corporation monitors commercial real estate loans based on collateral and risk grade criteria, as well as the levels of owner-occupied versus non-owner occupied loans. Construction Construction loans are underwritten utilizing a combination of tools and techniques including feasibility and market studies, independent appraisals and appraisal reviews, absorption and interest rate sensitivity analysis as well as the financial analysis of the developer and all guarantors. Construction loans are monitored by either in house or third party inspectors limiting advances to a percentage of costs or stabilized project value. These loans frequently involve the disbursement of significant funds with the repayment dependent upon the successful completion and, where necessary, the future stabilization of the project. The predominant inherent risk of this portfolio is associated with the borrower's ability to successfully complete a project on time, within budget and stabilize the projected as originally projected. Consumer and Residential With respect to residential loans that are secured by 1-4 family residences, which are typically owner occupied, the Corporation generally establishes a maximum loan-to-value ratio and requires private mortgage insurance if that ratio is exceeded. Home equity loans are secured by a subordinate interest in 1-4 family residences, and consumer loans are secured by consumer assets such as automobiles or recreational vehicles. Some consumer loans, such as small installment loans and certain lines of credit, are unsecured. Repayment of these loans is primarily dependent on the personal income and credit rating of the borrowers and can also be impacted by changes in property values. Risk is mitigated by the fact that the loans are of smaller individual amounts and spread over a large number of borrowers. The allowance for credit losses increased $427,000 during the three months ended September 30, 2022. The allowance for credit losses increased $31.3 million for the nine months ended September 30, 2022, primarily due to $16.6 million of allowance for credit losses on PCD loans acquired in the Level One acquisition established through accounting adjustments on the acquisition date. In addition, a provision of $14.0 million was recorded to establish an allowance for credit losses on non-PCD loans acquired in the Level One acquisition. The allowance also includes net recoveries of $427,000 and $751,000 for the three and nine months ended September 30, 2022, respectively.

The following tables show the composition of the loan portfolio and credit quality characteristics by collateral classification, excluding loans held for sale. Loans held for sale at September 30, 2022 and December 31, 2021, were $25.4 million and $11.2 million, respectively. The following table illustrates the composition of the Corporation’s loan portfolio by loan class for the periods indicated: September 30, 2022 December 31, 2021 Commercial and industrial loans $ 3,330,529 $ 2,714,565 Agricultural land, production and other loans to farmers 221,954 246,442 Real estate loans: Construction 828,923 523,066 Commercial real estate, non-owner occupied 2,299,272 2,135,459 Commercial real estate, owner occupied 1,268,567 986,720 Residential 1,990,668 1,159,127 Home equity 621,619 523,754 Individuals' loans for household and other personal expenditures 173,225 146,092 Public finance and other commercial loans 915,245 806,636 Loans $ 11,650,002 $ 9,241,861 The Level One acquisition added $1.6 billion in loans at acquisition, which included $43.5 million of Paycheck Protection Program ("PPP") loans. Additional details of the Level One acquisition are included in NOTE 2. ACQUISITIONS of these Notes to Consolidated Condensed Financial Statements. As of September 30, 2022, the Corporation had $11.2 million of PPP loans compared to the December 31, 2021 balance of $106.6 million. Additional details of the PPP are included in The CARES Act and the Paycheck Protection Program sections of the "COVID-19 UPDATE AND RELATED LEGISLATIVE ACTION" in the Management’s Discussion and Analysis of Financial Condition and Results of Operations included in this Form 10-Q. Credit Quality As part of the ongoing monitoring of the credit quality of the Corporation's loan portfolio, management tracks certain credit quality indicators including trends related to: (i) the level of criticized commercial loans, (ii) net charge-offs, (iii) non-performing loans, (iv) covenant failures and (v) the general national and local economic conditions. The Corporation utilizes a risk grading of pass, special mention, substandard, doubtful and loss to assess the overall credit quality of large commercial loans. All large commercial credit grades are reviewed at a minimum of once a year for pass grade loans. Loans with grades below pass are reviewed more frequently depending on the grade. A description of the general characteristics of these grades is as follows: • Pass - Loans that are considered to be of acceptable credit quality. • Special Mention - Loans which possess some credit deficiency or potential weakness, which deserves close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Corporation's credit position at some future date. Special mention assets are not adversely classified and do not expose the Corporation to sufficient risk to warrant adverse classification. • Substandard - A substandard loan is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified have a well-defined weakness that jeopardizes the liquidation of the debt. They are characterized by the distinct possibility that the Corporation will sustain some loss if the deficiencies are not corrected. • Doubtful - Loans that have all of the weaknesses of those classified as Substandard. However, based on currently existing facts, conditions and values, these weaknesses make full collection of principal highly questionable and improbable. • Loss – Loans that are considered uncollectible and of such little value that continuing to carry them as an asset is not warranted. Loans will be classified as Loss when it is neither practical or desirable to defer writing off or reserving all or a portion of a basically worthless asset, even though partial recovery may be possible at some time in the future. The following tables summarize the risk grading of the Corporation’s loan portfolio by loan class and by year of origination for the years indicated. Consumer loans are not risk graded. For the purposes of this disclosure, the consumer loans are classified in the following manner: loans that are less than 30 days past due are Pass, loans 30-89 days past due are Special Mention and loans greater than 89 days past due are Substandard. The entire balance of a loan is considered delinquent if the minimum payment contractually required to be made is not received by the specified due date. Commercial and industrial loan balances as of September 30, 2022 include PPP loans with an origination year of 2021 and 2020 of $11.1 million and $156,000, respectively. Commercial and industrial loan balances as of December 31, 2021 include PPP loans with an origination year of 2021 and 2020 of $100.3 million and $6.3 million, respectively.

At the time the accrual is discontinued, all unpaid accrued interest is reversed against earnings. Interest income accrued in prior years, if any, is charged to the allowance for credit losses. Payments subsequently received on non-accrual loans are applied to principal. A loan is returned to accrual status when principal and interest are no longer past due and collectability is probable, typically after a minimum of six consecutive months of performance. The following table summarizes the Corporation’s non-accrual loans by loan class for the periods indicated: September 30, 2022 December 31, 2021 Non-Accrual Loans Non-Accrual Loans with no Allowance for Credit Losses Non-Accrual Loans Non-Accrual Loans with no Allowance for Credit Losses Commercial and industrial loans $ 2,945 $ 1,354 $ 7,598 $ 263 Agricultural land, production and other loans to farmers 57 — 631 524 Real estate loans: Construction — — 685 — Commercial real estate, non-owner occupied 20,189 288 23,029 6,133 Commercial real estate, owner occupied 4,997 3,471 411 — Residential 10,703 722 9,153 2,160 Home equity 4,607 — 1,552 — Individuals' loans for household and other personal expenditures 10 — 3 — Loans $ 43,508 $ 5,835 $ 43,062 $ 9,080 There was no interest income recognized on non-accrual loans for the three and nine months ended September 30, 2022 or 2021. Determining fair value for collateral dependent loans requires obtaining a current independent appraisal of the collateral and applying a discount factor, which includes selling costs if applicable, to the value. The fair value of real estate is generally based on appraisals by qualified licensed appraisers. The appraisers typically determine the value of the real estate by utilizing an income or market valuation approach. If an appraisal is not available, the fair value may be determined by using a cash flow analysis. Fair value on other collateral such as business assets is typically ascertained by assessing, either singularly or some combination of, asset appraisals, accounts receivable aging reports, inventory listings and or customer financial statements. Both appraised values and values based on borrower’s financial information are discounted as considered appropriate based on age and quality of the information and current market conditions. The tables below present the amortized cost basis of collateral dependent loans by loan class and their respective collateral type, which are individually evaluated to determine expected credit losses. The increase in collateral dependent loans of $46.2 million, mostly due to the commercial and industrial loan class, is primarily related to loans from the acquisition of Level One.

A concession is deemed to be granted when, as a result of the restructuring, the Corporation does not expect to collect all original amounts due, including interest accrued at the original contract rate. If the payment of principal at original maturity is primarily dependent on the value of collateral, the current value of the collateral is considered in determining whether the principal will be repaid. The following tables summarize troubled debt restructures in the Corporation's loan portfolio that occurred during the three and nine months ended September 30, 2022 and 2021.

The following tables summarize troubled debt restructures that occurred during the twelve month ended September 30, 2021, that subsequently defaulted during the period indicated and remained in default at period end. For purposes of this schedule, a loan is considered in default if it is 30-days or more past due. There were no loans that subsequently defaulted during the three and nine months ended September 30, 2022.

Commercial troubled debt restructures that are not individually evaluated for a specific reserve are included in the calculation of allowance for credit losses through the loan segment loss analysis. For all consumer loan modifications, an evaluation to identify if a troubled debt restructure has occurred is performed prior to making the modification. Any subsequent deterioration is addressed through the charge-off process or through a specific reserve allocation included in the allowance for credit losses. Consumer troubled debt restructures that are not individually evaluated for a specific reserve are included in the calculation of the allowance for credit losses through the loan segment loss analysis. Consumer loans secured by residential real estate properties for which formal foreclosure proceedings are in process totaled $2.0 million and $3.9 million at September 30, 2022 and 2021. Purchased Credit Deteriorated Loans The Corporation acquired Level One on April 1, 2022 and performed an evaluation of the loan portfolio in which there were loans that, at acquisition, had more than an insignificant amount of credit quality deterioration. The carrying amount of those loans is shown in the table below: Level One Purchase price of loans at acquisition $ 41,347 CECL Day 1 PCD ACL 16,599 Par value of acquired loans at acquisition $ 57,946 Allowance for Credit Losses on Loans The Allowance for Credit Losses on Loans ("ACL - Loans") is a valuation account that is deducted from the amortized cost basis of loans to present the net amount expected to be collected on loans over the contractual term. The ACL - Loans is adjusted by the provision for credit losses, which is reported in earnings, and reduced by charge offs for loans, net of recoveries. Provision for credit losses on loans reflects the totality of actions taken on all loans for a particular period including any necessary increases or decreases in the allowance related to changes in credit loss expectations associated with specific loans or pools of loans. Loans are charged off against the allowance when the uncollectibility of the loan is confirmed. Expected recoveries do not exceed the aggregate of amounts previously charged off and expected to be charged off. The allowance represents the Corporation’s best estimate of current expected credit losses on loans using relevant available information, from internal and external sources, related to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. The current expected credit loss ("CECL") calculation is performed and evaluated quarterly and losses are estimated over the expected life of the loan. The level of the allowance for credit losses is believed to be adequate to absorb all expected future losses inherent in the loan portfolio at the measurement date. In calculating the allowance for credit losses, the loan portfolio was pooled into ten loan segments with similar risk characteristics. Common characteristics include the type or purpose of the loan, underlying collateral and historical/expected credit loss patterns. In developing the loan segments, the Corporation analyzed the degree of correlation in how loans within each portfolio respond when subjected to varying economic conditions and scenarios as well as other portfolio stress factors. The expected credit losses are measured over the life of each loan segment utilizing the Probability of Default / Loss Given Default methodology combined with economic forecast models to estimate the current expected credit loss inherent in the loan portfolio. This approach is also leveraged to estimate the expected credit losses associated with unfunded loan commitments incorporating expected utilization rates. The Corporation sub-segmented certain commercial portfolios by risk level and certain consumer portfolios by delinquency status where appropriate. The Corporation utilized a four-quarter reasonable and supportable economic forecast period followed by a six-quarter, straight-line reversion period to the historical macroeconomic mean for the remaining life of the loans. Econometric modeling was performed using historical default rates and a selection of economic forecast scenarios published by Moody’s to develop a range of estimated credit losses for which to determine the best credit loss estimate within. Macroeconomic factors utilized in the modeling process include the national unemployment rate, BBB US corporate index, CRE price index and the home price index. The Corporation qualitatively adjusts model results for risk factors that are not inherently considered in the quantitative modeling process, but are nonetheless relevant in assessing the expected credit losses within the loan portfolio. These adjustments may increase or decrease the estimate of expected credit losses based upon the assessed level of risk for each qualitative factor. The various risks that may be considered in making qualitative adjustments include, among other things, the impact of (i) changes in the nature and volume of the loan portfolio, (ii) changes in the existence, growth and effect of any concentrations in credit, (iii) changes in lending policies and procedures, including changes in underwriting standards and practices for collections, write-offs, and recoveries, (iv) changes in the quality of the credit review function, (v) changes in the experience, ability and depth of lending management and staff, and (vi) other environmental factors of a borrower such as regulatory, legal and technological considerations, as well as competition. In some cases, management may determine that an individual loan exhibits unique risk characteristics which differentiate the loan from other loans within the loan segments. In such cases, the loans are evaluated for expected credit losses on an individual basis and excluded from the collective evaluation. Specific reserve allocations of the allowance for credit losses are determined by analyzing the borrower’s ability to repay amounts owed, collateral deficiencies, the relative risk grade of the loan and economic conditions affecting the borrower’s industry, among other things. A loan is considered to be collateral dependent when, based upon management's assessment, the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. In such cases, expected credit losses are based on the fair value of the collateral at the measurement date, adjusted for estimated selling costs if satisfaction of the loan depends on the sale of the collateral. The fair value of collateral supporting collateral dependent loans is evaluated on a quarterly basis. No allowance for credit losses has been recognized for PPP loans as such loans are fully guaranteed by the Small Business Administration ("SBA"). The risk characteristics of the Corporation’s portfolio segments are as follows: Commercial Commercial lending is primarily based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not be as expected and the collateral securing these loans may fluctuate in value. Most commercial loans are secured by the tangible assets being financed such as equipment or real estate or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee. Other loans may be unsecured, secured but under-collateralized or otherwise made on the basis of the enterprise value of an organization. In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its customers. Commercial real estate Commercial real estate loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts and the repayment of these loans is generally dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. The Corporation monitors commercial real estate loans based on collateral and risk grade criteria, as well as the levels of owner-occupied versus non-owner occupied loans. Construction Construction loans are underwritten utilizing a combination of tools and techniques including feasibility and market studies, independent appraisals and appraisal reviews, absorption and interest rate sensitivity analysis as well as the financial analysis of the developer and all guarantors. Construction loans are monitored by either in house or third party inspectors limiting advances to a percentage of costs or stabilized project value. These loans frequently involve the disbursement of significant funds with the repayment dependent upon the successful completion and, where necessary, the future stabilization of the project. The predominant inherent risk of this portfolio is associated with the borrower's ability to successfully complete a project on time, within budget and stabilize the projected as originally projected. Consumer and Residential With respect to residential loans that are secured by 1-4 family residences, which are typically owner occupied, the Corporation generally establishes a maximum loan-to-value ratio and requires private mortgage insurance if that ratio is exceeded. Home equity loans are secured by a subordinate interest in 1-4 family residences, and consumer loans are secured by consumer assets such as automobiles or recreational vehicles. Some consumer loans, such as small installment loans and certain lines of credit, are unsecured. Repayment of these loans is primarily dependent on the personal income and credit rating of the borrowers and can also be impacted by changes in property values. Risk is mitigated by the fact that the loans are of smaller individual amounts and spread over a large number of borrowers. The allowance for credit losses increased $427,000 during the three months ended September 30, 2022. The allowance for credit losses increased $31.3 million for the nine months ended September 30, 2022, primarily due to $16.6 million of allowance for credit losses on PCD loans acquired in the Level One acquisition established through accounting adjustments on the acquisition date. In addition, a provision of $14.0 million was recorded to establish an allowance for credit losses on non-PCD loans acquired in the Level One acquisition. The allowance also includes net recoveries of $427,000 and $751,000 for the three and nine months ended September 30, 2022, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTS Risk Management Objective of Using Derivatives The Corporation is exposed to certain risks arising from both its business operations and economic conditions. The Corporation principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Corporation manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities and through the use of derivative financial instruments. Specifically, the Corporation enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Corporation’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Corporation’s known or expected cash payments principally related to certain variable-rate liabilities. The Corporation also has derivatives that are a result of a service the Corporation provides to certain qualifying customers, and, therefore, are not used to manage interest rate risk in the Corporation’s assets or liabilities. The Corporation manages a matched book with respect to its derivative instruments offered as a part of this service to its customers in order to minimize its net risk exposure resulting from such transactions. Derivatives Designated as Hedges The Corporation’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish these objectives, the Corporation primarily uses interest rate swaps and interest rate caps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the payment of fixed amounts to a counterparty in exchange for the Corporation receiving variable payments over the life of the agreements without exchange of the underlying notional amount. Interest rate caps designated as cash flow hedges involve the receipt of variable amounts from a counterparty if interest rates rise above the strike rate on the contract in exchange for an up-front premium. As of September 30, 2022 the Corporation had one interest rate swap with a notional amount of $10.0 million that was designated as a cash flow hedge. As of December 31, 2021, the Corporation had four interest rate swaps with a notional amount of $60.0 million that were designated as cash flow hedges. A $24.0 million interest rate swap, which was used to hedge the variable cash outflows (Ameribor-based) associated with a brokered deposit, matured in the first quarter of 2022. Two interest rate swaps totaling $26.0 million, which were used to hedge the variable cash outflows (LIBOR-based) associated with existing trust preferred securities when the outflows converted from a fixed rate to variable rate in September 2012, matured in the third quarter of 2022. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income (loss) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During 2022, $10.0 million of interest rate swaps were used to hedge the variable cash outflows (LIBOR-based) associated with one Federal Home Loan Bank advance. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. During the three and nine months ended September 30, 2022 and 2021, the Corporation did not recognize any ineffectiveness. Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest expense as interest payments are made on the Corporation's variable-rate liabilities. During the next twelve months, the Corporation expects to reclassify $167,000 from accumulated other comprehensive income (loss) to interest income. The following table summarizes the Corporation's derivatives designated as hedges: Asset Derivatives Liability Derivatives September 30, 2022 December 31, 2021 September 30, 2022 December 31, 2021 Balance Fair Balance Fair Balance Fair Balance Fair Cash flow hedges: Interest rate swaps on borrowings Other Assets $ 167 Other Assets $ — Other Liabilities $ — Other Liabilities $ 835 The amount of loss recognized in other comprehensive income (loss) is included in the table below for the periods indicated.

Derivatives not designated as hedges are not speculative and result from a service the Corporation provides to certain customers. The Corporation executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting interest rate swaps that the Corporation executes with a third party, such that the Corporation minimizes its net risk exposure resulting from such transactions. As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. Commitments to fund certain mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of mortgage loans to third party investors are considered derivatives. It is the Corporation's practice to enter into forward commitments for the future delivery of residential mortgage loans when interest rate lock commitments are entered into in order to economically hedge the effect of changes in interest rates resulting from its commitments to fund the loans. These mortgage banking derivatives are not designated in hedge relationships. Fair values were estimated based on changes in mortgage interest rates from the date of the commitments. Changes in the fair value of these mortgage banking derivatives are included in net gains and fees on sales of loans. The table below presents the fair value of the Corporation’s non-designated hedges, as well as their classification on the Balance Sheet, as of September 30, 2022, and December 31, 2021.

The counterparties approved by the Corporation are usually financial institutions, which are well capitalized and have credit ratings through Moody’s and/or Standard & Poor’s at or above investment grade. The Corporation’s control of such risk is through quarterly financial reviews, comparing mark-to-market values with policy limitations, credit ratings and collateral pledging. Credit-risk-related Contingent Features The Corporation has agreements with certain of its derivative counterparties that contain a provision where if the Corporation fails to maintain its status as a well or adequately capitalized institution, then the Corporation could be required to terminate or fully collateralize all outstanding derivative contracts. Additionally, the Corporation has agreements with certain of its derivative counterparties that contain a provision where if the Corporation defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Corporation could also be declared in default on its derivative obligations. As of September 30, 2022, the termination value of derivatives in a net liability position related to these agreements was $51,000. As of September 30, 2022, the Corporation has minimum collateral posting thresholds with certain of its derivative counterparties and has posted collateral of $195,000. While the Corporation did not breach any of these provisions as of September 30, 2022, if it had, the Corporation could have been required to settle its obligations under the agreements at their termination value.

Fair Value Disclosures [Abstract]
DISCLOSURES ABOUT FAIR VALUE OF ASSETS AND LIABILITIES	DISCLOSURES ABOUT FAIR VALUE OF ASSETS AND LIABILITIES The Corporation used fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The accounting guidance defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. ASC 820 applies only when other guidance requires or permits assets or liabilities to be measured at fair value; it does not expand the use of fair value in any new circumstances. As defined in ASC 820, fair value is the price to sell an asset or transfer a liability in an orderly transaction between market participants. It represents an exit price at the measurement date. Market participants are buyers and sellers, who are independent, knowledgeable, and willing and able to transact in the principal (or most advantageous) market for the asset or liability being measured. Current market conditions, including imbalances between supply and demand, are considered in determining fair value. The Corporation values its assets and liabilities in the principal market where it sells the particular asset or transfers the liability with the greatest volume and level of activity. In the absence of a principal market, the valuation is based on the most advantageous market for the asset or liability (i.e., the market where the asset could be sold or the liability transferred at a price that maximizes the amount to be received for the asset or minimizes the amount to be paid to transfer the liability). Valuation inputs refer to the assumptions market participants would use in pricing a given asset or liability. Inputs can be observable or unobservable. Observable inputs are those assumptions which market participants would use in pricing the particular asset or liability. These inputs are based on market data and are obtained from a source independent of the Corporation. Unobservable inputs are assumptions based on the Corporation’s own information or estimate of assumptions used by market participants in pricing the asset or liability. Unobservable inputs are based on the best and most current information available on the measurement date. All inputs, whether observable or unobservable, are ranked in accordance with a prescribed fair value hierarchy which gives the highest ranking to quoted prices (unadjusted) in active markets for identical assets or liabilities (Level 1) and the lowest ranking to unobservable inputs for which there is little or no market activity (Level 3). Fair values for assets or liabilities classified as Level 2 are based on one or a combination of the following factors: (i) quoted prices for similar assets; (ii) observable inputs for the asset or liability, such as interest rates or yield curves; or (iii) inputs derived principally from or corroborated by observable market data. The level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Corporation considers an input to be significant if it drives 10 percent or more of the total fair value of a particular asset or liability. RECURRING MEASUREMENTS Assets and liabilities are considered to be measured at fair value on a recurring basis if fair value is measured regularly (i.e., daily, weekly, monthly or quarterly). Recurring valuation occurs at a minimum on the measurement date. Assets and liabilities are considered to be measured at fair value on a nonrecurring basis if the fair value measurement of the instrument does not necessarily result in a change in the amount recorded on the balance sheet. Generally, nonrecurring valuation is the result of the application of other accounting pronouncements which require assets or liabilities to be assessed for impairment or recorded at the lower of cost or fair value. The fair value of assets or liabilities transferred in or out of Level 3 is measured on the transfer date, with any additional changes in fair value subsequent to the transfer considered to be realized or unrealized gains or losses. Following is a description of the valuation methodologies used for instruments measured at fair value on a recurring basis and recognized in the accompanying balance sheets, as well as the general classification of such instruments pursuant to the valuation hierarchy. Investment Securities Where quoted prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities include U.S. Treasury securities. Where significant observable inputs, other than Level 1 quoted prices, are available, securities are classified within Level 2 of the valuation hierarchy. Level 2 securities include U.S. government-sponsored agency and mortgage-backed securities, state and municipal securities and corporate obligations securities. In certain cases where Level 1 or Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy and include state and municipal securities, U.S. government-sponsored mortgage-backed securities and corporate obligations securities. Level 3 fair value for securities was determined using a discounted cash flow model that incorporated market estimates of interest rates and volatility in markets that have not been active. Third party vendors compile prices from various sources and may apply such techniques as matrix pricing to determine the value of identical or similar investment securities (Level 2). Matrix pricing is a mathematical technique widely used in the banking industry to value investment securities without relying exclusively on quoted prices for specific investment securities but rather relying on the investment securities’ relationship to other benchmark quoted investment securities. Any investment security not valued based upon the methods above are considered Level 3. Derivative Financial Agreements See information regarding the Corporation’s derivative financial agreements in NOTE 7. DERIVATIVE FINANCIAL INSTRUMENTS of these Notes to Consolidated Condensed Financial Statements. The following table presents the fair value measurements of assets and liabilities recognized in the accompanying balance sheets measured at fair value on a recurring basis and the level within the ASC 820 fair value hierarchy in which the fair value measurements fall at September 30, 2022, and December 31, 2021.

Nonrecurring Measurements Following is a description of valuation methodologies used for instruments measured at fair value on a non-recurring basis and recognized in the accompanying balance sheets, as well as the general classification of such instruments pursuant to the valuation hierarchy at September 30, 2022, and December 31, 2021. Fair Value Measurements Using September 30, 2022 Fair Value Quoted Prices in Significant Other Significant Unobservable Collateral dependent loans $ 54,756 $ — $ — $ 54,756 Fair Value Measurements Using December 31, 2021 Fair Value Quoted Prices in Significant Other Significant Unobservable Collateral dependent loans $ 24,491 $ — $ — $ 24,491 Other real estate owned 96 — — 96 Collateral Dependent Loans and Other Real Estate Owned Determining fair value for collateral dependent loans and other real estate requires obtaining a current independent appraisal of the collateral and applying a discount factor, which includes selling costs if applicable, to the value. The fair value of real estate is generally based on appraisals by qualified licensed appraisers. The appraisers typically determine the value of the real estate by utilizing an income or market valuation approach. If an appraisal is not available, the fair value may be determined by using a cash flow analysis. Fair value on other collateral such as business assets is typically ascertained by assessing, either singularly or some combination of, asset appraisals, accounts receivable aging reports, inventory listings and or customer financial statements. Both appraised values and values based on borrower’s financial information are discounted as considered appropriate based on age and quality of the information and current market conditions. Unobservable (Level 3) Inputs The following table presents quantitative information about unobservable inputs used in recurring and nonrecurring Level 3 fair value measurements, other than goodwill, at September 30, 2022 and December 31, 2021.

State and Municipal Securities, Corporate Obligations and U.S. Government-sponsored Mortgage-Backed Securities The significant unobservable inputs used in the fair value measurement of the Corporation's state and municipal securities, corporate obligations and U.S. Government-sponsored mortgage-backed securities are premiums for unrated securities and marketability discounts. Significant increases or decreases in either of those inputs in isolation would result in a significantly lower or higher fair value measurement.

SHARE-BASED COMPENSATION

SHARE-BASED COMPENSATION	9 Months Ended

Share-Based Payment Arrangement [Abstract]
SHARE-BASED COMPENSATION	SHARE-BASED COMPENSATION Stock options and RSAs have been issued to directors, officers and other management employees under the Corporation's 2009 Long-term Equity Incentive Plan, the 2019 Long-term Equity Incentive Plan, and the Equity Compensation Plan for Non-Employee Directors. The stock options, which have a ten year life, become 100 percent vested based on time ranging from one year to two years and are fully exercisable when vested. Option exercise prices equal the Corporation's common stock closing price on NASDAQ on the date of grant. The RSAs issued to employees and non-employee directors provide for the issuance of shares of the Corporation's common stock at no cost to the holder and generally vest after three years. The RSAs vest only if the employee is actively employed by the Corporation on the vesting date and, therefore, any unvested shares are forfeited. For non-employee directors, the RSAs vest only if the non-employee director remains as an active board member on the vesting date and, therefore, any unvested shares are forfeited. The RSAs for employees and non-employee directors are either immediately vested at retirement, disability or death, or, continue to vest after retirement, disability or death, depending on the plan under which the shares were granted. The Corporation’s 2019 ESPP provides eligible employees of the Corporation and its subsidiaries an opportunity to purchase shares of common stock of the Corporation through quarterly offerings financed by payroll deductions. The price of the stock to be paid by the employees shall be equal to 85 percent of the average of the closing price of the Corporation’s common stock on each trading day during the offering period. However, in no event shall such purchase price be less than the lesser of an amount equal to 85 percent of the market price of the Corporation’s stock on the offering date or an amount equal to 85 percent of the market value on the date of purchase. Common stock purchases are made quarterly and are paid through advance payroll deductions up to a calendar year maximum of $25,000. Compensation expense related to unvested share-based awards is recorded by recognizing the unamortized grant date fair value of these awards over the remaining service periods of those awards, with no change in historical reported fair values and earnings. Awards are valued at fair value in accordance with provisions of share-based compensation guidance and are recognized on a straight-line basis over the service periods of each award. To complete the exercise of vested stock options, RSA’s and ESPP options, the Corporation generally issues new shares from its authorized but unissued share pool. Share-based compensation for the three and nine months ended September 30, 2022 was $1.2 million and $3.4 million, respectively, compared to $1.2 million and $3.6 million, respectively, for the three and nine months ended September 30, 2021. Share-based compensation has been recognized as a component of salaries and benefits expense in the accompanying Consolidated Condensed Statements of Income. Share-based compensation expense recognized in the Consolidated Condensed Statements of Income is based on awards ultimately expected to vest and is reduced for estimated forfeitures. Share-based compensation guidance requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods, if actual forfeitures differ from those estimates. Pre-vesting forfeitures were estimated to be approximately 0.5 percent for the nine months ended September 30, 2022, based on historical experience. The following table summarizes the components of the Corporation's share-based compensation awards recorded as an expense and the income tax benefit of such awards. Three Months Ended Nine Months Ended 2022 2021 2022 2021 Stock and ESPP Options Pre-tax compensation expense $ 15 $ 16 $ 64 $ 131 Income tax expense (benefit) — — (74) (92) Stock and ESPP option expense, net of income taxes $ 15 $ 16 $ (10) $ 39 Restricted Stock Awards Pre-tax compensation expense $ 1,171 $ 1,201 $ 3,366 $ 3,484 Income tax expense (benefit) (332) (136) (792) (619) Restricted stock awards expense, net of income taxes $ 839 $ 1,065 $ 2,574 $ 2,865 Total Share-Based Compensation Pre-tax compensation expense $ 1,186 $ 1,217 $ 3,430 $ 3,615 Income tax expense (benefit) (332) (136) (866) (711) Total share-based compensation expense, net of income taxes $ 854 $ 1,081 $ 2,564 $ 2,904 The grant date fair value of ESPP options was estimated to be approximately $15,000 at the beginning of the July 1, 2022 quarterly offering period. The ESPP options vested during the three months ending September 30, 2022, leaving no unrecognized compensation expense related to unvested ESPP options at September 30, 2022. Stock option activity under the Corporation's stock option plans as of September 30, 2022 and changes during the nine months ended September 30, 2022, were as follows: Number of Weighted-Average Exercise Price Weighted Average Remaining Aggregate Outstanding at January 1, 2022 28,500 $ 17.14 Transferred Options from Level One 148,600 $ 18.84 Exercised (20,095) $ 16.74 Outstanding September 30, 2022 157,005 $ 18.80 2.69 $ 3,121,261 Vested and Expected to Vest at September 30, 2022 157,005 $ 18.80 2.69 $ 3,121,261 Exercisable at September 30, 2022 157,005 $ 18.80 2.69 $ 3,121,261 The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between the Corporation's closing stock price on the last trading day of the first nine months of 2022 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their stock options on September 30, 2022. The amount of aggregate intrinsic value will change based on the fair market value of the Corporation's common stock. The aggregate intrinsic value of stock options exercised during the nine months ended September 30, 2022 and 2021 was $470,000 and $559,000, respectively. Cash receipts of stock options exercised during this same period were $336,000 and $198,000, respectively. The following table summarizes information on unvested RSAs outstanding as of September 30, 2022: Number of Shares Weighted-Average Unvested RSAs at January 1, 2022 411,259 $ 35.86 Granted 129,040 $ 40.60 Vested (112,443) $ 37.18 Forfeited (11,775) $ 36.54 Unvested RSAs at September 30, 2022 416,081 $ 36.95 As of September 30, 2022, unrecognized compensation expense related to RSAs was $9.9 million and is expected to be recognized over a weighted-average period of 2.0 years. The Corporation did not have any unrecognized compensation expense related to stock options as of September 30, 2022.

Earnings Per Share [Abstract]
NET INCOME PER COMMON SHARE	NET INCOME PER COMMON SHARE Basic net income per common share is computed by dividing net income available to common stockholders by the weighted-average common shares outstanding during the reporting period. Diluted net income per common share is computed by dividing net income available to common stockholders by the combination of the weighted-average common shares outstanding during the reporting period and all potentially dilutive common shares. Potentially dilutive common shares include stock options and RSAs issued under the Corporation's share-based compensation plans. Potentially dilutive common shares are excluded from the computation of diluted earnings per common share in the periods where the effect would be antidilutive. The following table reconciles basic and diluted net income per common share for the three and nine months ended September 30, 2022 and 2021.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Financial Statement Preparation	Financial Statement PreparationThe Consolidated Condensed Balance Sheet of the Corporation as of December 31, 2021, has been derived from the audited consolidated balance sheet of the Corporation as of that date. Certain information and note disclosures normally included in the Corporation’s annual financial statements, prepared in accordance with accounting principles generally accepted in the United States of America, have been condensed or omitted. These consolidated condensed financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2021 filed with the Securities and Exchange Commission. The results of operations for the three and nine months ended September 30, 2022, are not necessarily indicative of the results to be expected for the year. Reclassifications have been made to prior financial statements to conform to the current financial statement presentation. These reclassifications had no effect on net income. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for credit losses and fair value of financial instruments.
New Accounting Pronouncements Not Yet Adopted	The Corporation did not adopt any new accounting pronouncements during the first nine months of 2022. The Corporation continually monitors potential accounting pronouncements and the following pronouncements have been deemed to have the most applicability to the Corporation's financial statements: New Accounting Pronouncements Not Yet Adopted FASB Accounting Standards Updates - No. 2020-04 - Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting Summary - The FASB issued ASU No. 2020-04 to provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. LIBOR and other interbank offered rates are widely used benchmarks or reference rates in the United States and globally. Trillions of dollars in loans, derivatives, and other financial contracts reference LIBOR, the benchmark interest rate banks use to make short-term loans to each other. With global capital markets expected to move away from LIBOR and other interbank offered rates and move toward rates that are more observable or transaction based and less susceptible to manipulation, the FASB launched a broad project in late 2018 to address potential accounting challenges expected to arise from the transition. The new guidance provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. The ASU is intended to help stakeholders during the global market-wide reference rate transition period. Entities may apply this ASU as of the beginning of an interim period that includes the March 12, 2020 issuance date of the ASU, through December 31, 2022. The Corporation expects to adopt the practical expedients included in the ASU prior to December 31, 2022. The Corporation is implementing a transition plan to identify and modify its loans and other financial instruments with attributes that are either directly or indirectly influenced by LIBOR. The Corporation is assessing ASU 2020-04 and its impact on the Corporation's transition away from LIBOR for its loans and other financial instruments. FASB Accounting Standards Updates - No. 2021-01 - Reference Rate Reform (Topic 848): Scope Summary - The FASB has published ASU 2021-01, Reference Rate Reform. ASU 2021-01 clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The ASU also amends the expedients and exceptions in Topic 848 to capture the incremental consequences of the scope clarification and to tailor the existing guidance to derivative instruments affected by the discounting transition. An entity may elect to apply the amendments in this Update on a full retrospective basis as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or on a prospective basis to new modifications from any date within an interim period that includes or is subsequent to the date of the issuance of a final Update, up to the date that financial statements are available to be issued. If an entity elects to apply any of the amendments in this Update for an eligible hedging relationship, any adjustments as a result of those elections must be reflected as of the date the entity applies the election. The amendments in this Update do not apply to contract modifications made after December 31, 2022, new hedging relationships entered into after December 31, 2022, and existing hedging relationships evaluated for effectiveness in periods after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that apply certain optional expedients in which the accounting effects are recorded through the end of the hedging relationship (including periods after December 31, 2022). The Corporation expects to adopt the practical expedients included in the ASU prior to December 31, 2022. The Corporation is assessing ASU 2021-01 and its impact on the Corporation's transition away from LIBOR for its loans and other financial instruments. FASB Accounting Standards Updates - No. 2021-08 - Business Combinations (Topic 805) - Accounting for Contract Assets and Contract Liabilities from Contracts with Customers Summary - The FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers , that addresses diversity in practice related to the accounting for revenue contracts with customers acquired in a business combination. Under current GAAP, an acquirer generally recognizes assets acquired and liabilities assumed in a business combination, including contract assets and contract liabilities arising from revenue contracts with customers and other similar contracts that are accounted for in accordance with Topic 606 , Revenue from Contracts with Customers , at fair value on the acquisition date. The FASB indicates that some stakeholders indicated that it is unclear how an acquirer should evaluate whether to recognize a contract liability from a revenue contract with a customer acquired in a business combination after Topic 606 is adopted. Furthermore, it was identified that under current practice, the timing of payment (payment terms) of a revenue contract may subsequently affect the post-acquisition revenue recognized by the acquirer. To address this, the ASU requires entities to apply Topic 606 to recognize and measure contract assets and contract liabilities in a business combination. Finally, the amendments in the ASU improve comparability after the business combination by providing consistent recognition and measurement guidance for revenue contracts with customers acquired in a business combination and revenue contracts with customers not acquired in a business combination. For public business entities, the amendments are effective for fiscal years beginning after December 31, 2022, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 31, 2023, including interim periods within those fiscal years. The amendments in this Update should be applied prospectively to business combinations occurring on or after the effective date of the amendments. Early adoption of the amendments is permitted, including adoption in an interim period. An entity that early adopts in an interim period should apply the amendments (1) retrospectively to all business combinations for which the acquisition date occurs on or after the beginning of the fiscal year that includes the interim period or early application, and (2) prospectively to all business combinations that occur on or after the date of initial application. The Corporation is reviewing the terms of this guidance, but adoption of the standard is not expected to have a significant impact on the Corporation's financial statements or disclosures. FASB Accounting Standards Updates - Accounting Standards Update No. 2022-02 - Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures Summary - The FASB issued ASU No. 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings ("TDRs") and Vintage Disclosures , which is intended to improve the usefulness of information provided to investors about certain loan refinancings, restructurings, and writeoffs. The amendments in the new ASU eliminate the accounting guidance for TDRs by creditors that have adopted CECL while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors made to borrowers experiencing financial difficulty. The amendments also require that a public business entity disclose current-period gross writeoffs by year of origination for financing receivables and net investment in leases. Since the Corporation adopted CECL on January 1, 2021, the amendments in ASU 2022-02 are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Corporation is assessing ASU 2022-02 and its impact on the Corporation's disclosures. The Corporation expects to adopt this ASU in the first quarter of 2023.
