Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly the financial position, results of operations and comprehensive income, changes in stockholders’ equity, and cash flows of the Corporation and Parent Company for the periods presented, and all such adjustments are of a normal recurring nature. The consolidated financial statements include the accounts of all subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full year. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and revenues and expenses for the period. Actual results could differ significantly from those estimates. Estimates that are particularly susceptible to significant change include the determination of the ACLL and MSRs valuation. Management has evaluated subsequent events for potential recognition or disclosure. Within the tables presented, certain columns and rows may not sum due to the use of rounded numbers for disclosure purposes.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies The accounting and reporting policies of the Corporation conform to U.S. GAAP and to general practice within the financial services industry. A discussion of these policies can be found in Note 1 Summary of Significant Accounting Policies included in the Corporation’s 2021 Annual Report on Form 10-K. As a result of the irrevocable election to account for MSRs under the fair value measurement methodology, as permitted under ASC 860-50-35-3, there has been a change to the Corporation's significant accounting policies since December 31, 2021, which is described below. Mortgage Servicing Rights The Corporation sells residential mortgage loans in the secondary market and typically retains the rights to service the loans sold. Upon sale, a MSRs asset is capitalized, which represents the then current fair value of future net cash flows expected to be realized for performing servicing activities. On January 1, 2022, the Corporation made the irrevocable election to account for its MSRs asset under the fair value measurement method. As a result of the change, a cumulative effect adjustment of $2 million, increasing retained earnings on the consolidated balance sheets, was recognized. Under this methodology, changes in the fair value are recognized in earnings as they occur through mortgage banking, net on the consolidated statements of income. MSRs are not traded in active markets. A cash flow model is used to determine fair value. Key assumptions and estimates, including projected prepayment speeds, assumed servicing costs, ancillary income, costs to service delinquent loans, costs of foreclosure, and discount rates with option-adjusted spreads, used by this model are based on current market sources. Assumptions used to value MSRs are considered significant unobservable inputs. A separate third-party model is used to estimate prepayment speeds based on interest rates, housing turnover rates, estimated loan curtailment, anticipated defaults and other relevant factors. Fair value estimates from outside sources are received periodically to corroborate the results of the valuation model. New Accounting Pronouncements Adopted There were no applicable material accounting pronouncements adopted by the Corporation since December 31, 2021. Future Accounting Pronouncements The expected impact of applicable material accounting pronouncements recently issued or proposed but not yet required to be adopted are discussed in the table below. To the extent that the adoption of new accounting standards materially affects the Corporation's financial condition, results of operations, liquidity or disclosures, the impacts are discussed in the applicable sections of this financial review. Standard Description Date of anticipated adoption Effect on financial statements ASU 2022-02 Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures The FASB issued these amendments to eliminate accounting guidance for TDRs by creditors in Subtopic 310-40, Receivables-Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty, and to require that an entity disclose current-period gross writeoffs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, Financial Instruments-Credit Losses-Measured at Amortized Cost. The amendments in this Update are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, and should be applied prospectively, except as provided in the next sentence. For the transition method related to the recognition and measurement of TDRs, an entity has the option to apply a modified retrospective transition method, resulting in a cumulative-effect adjustment to retained earnings in the period of adoption. Early adoption is permitted if an entity has adopted the amendments in Update 2016-03, including adoption in an interim period. 1st Quarter 2023 Adoption of this amendment is not expected to have a material impact on the Corporation's results of operation, financial position or liquidity, but will result in additional disclosure requirements related to gross charge offs by vintage year and the removal of TDR disclosures, replaced by additional disclosures on the types of modifications of loans to borrowers experiencing financial difficulties.

Earnings Per Common Share	Jun. 30, 2022
Earnings Per Share [Abstract]
Earnings Per Common Share	Earnings Per Common Share Earnings per common share are calculated utilizing the two-class method. Basic earnings per common share are calculated by dividing the sum of distributed earnings to common shareholders and undistributed earnings allocated to common shareholders by the weighted average number of common shares outstanding. Diluted earnings per common share are calculated by dividing the sum of distributed earnings to common shareholders and undistributed earnings allocated to common shareholders by the weighted average number of common shares outstanding adjusted for the dilutive effect of common stock awards (outstanding stock options and unvested restricted stock awards). Presented below are the calculations for basic and diluted earnings per common share: Three Months Ended Jun 30, Six Months Ended Jun 30, (In Thousands, except per share data) 2022 2021 2022 2021 Net income $ 86,824 $ 91,007 $ 161,086 $ 185,307 Preferred stock dividends (2,875) (4,875) (5,750) (10,082) Net income available to common equity $ 83,949 $ 86,131 $ 155,336 $ 175,226 Common shareholder dividends (30,126) (27,620) (60,499) (55,280) Unvested share-based payment awards (205) (203) (415) (412) Undistributed earnings $ 53,618 $ 58,309 $ 94,422 $ 119,533 Undistributed earnings allocated to common shareholders $ 53,257 $ 57,887 $ 93,807 $ 118,722 Undistributed earnings allocated to unvested share-based payment awards 361 422 615 810 Undistributed earnings $ 53,618 $ 58,309 $ 94,422 $ 119,533 Basic Distributed earnings to common shareholders $ 30,126 $ 27,620 $ 60,499 $ 55,280 Undistributed earnings allocated to common shareholders 53,257 57,887 93,807 118,722 Total common shareholders earnings, basic $ 83,383 $ 85,506 $ 154,306 $ 174,002 Diluted Distributed earnings to common shareholders $ 30,126 $ 27,620 $ 60,499 $ 55,280 Undistributed earnings allocated to common shareholders 53,257 57,887 93,807 118,722 Total common shareholders earnings, diluted $ 83,383 $ 85,506 $ 154,306 $ 174,002 Weighted average common shares outstanding 149,083 152,042 148,933 152,198 Effect of dilutive common stock awards 1,121 1,339 1,332 1,275 Diluted weighted average common shares outstanding 150,203 153,381 150,265 153,473 Basic earnings per common share $ 0.56 $ 0.56 $ 1.04 $ 1.14 Diluted earnings per common share $ 0.56 $ 0.56 $ 1.03 $ 1.13 Anti-dilutive common stock options of approximately 3 million for the three and six months ended June 30, 2022 and 2021 were excluded from the earnings per common share calculation.

Stock-Based Compensation	Jun. 30, 2022
Retirement Benefits [Abstract]
Stock-Based Compensation	Stock-Based Compensation The fair values of stock options and restricted stock awards are amortized as compensation expense on a straight-line basis over the vesting period of the grants. For colleagues who meet the definition of retirement eligible under the 2017 Incentive Compensation Plan and the 2020 Incentive Compensation Plan, expenses related to stock options and restricted stock awards are fully recognized on the date the colleague meets the definition of normal or early retirement. Compensation expense recognized is included in personnel expense on the consolidated statements of income. A summary of the Corporation’s stock option activity for the six months ended June 30, 2022 is presented below: Stock Options Shares (a) Weighted Average Weighted Average Remaining Contractual Term Aggregate Intrinsic Value (a) Outstanding at December 31, 2021 4,814 $ 20.72 5.96 years $ 12,532 Exercised 367 17.64 Outstanding at June 30, 2022 4,447 $ 20.97 5.56 years $ 1,770 Options Exercisable at June 30, 2022 3,805 $ 21.28 5.24 years $ 1,341 (a) In thousands Intrinsic value represents the amount by which the fair market value of the underlying stock exceeds the exercise price of the stock option. For the six months ended June 30, 2022, the intrinsic value of stock options exercised was $3 million compared to $6 million for the six months ended June 30, 2021. For the six months ended June 30, 2022, the total fair value of stock options vested was $2 million compared to $3 million for the six months ended June 30, 2021. The Corporation recognized compensation expense for the vesting of stock options of approximately $469,000 for the six months ended June 30, 2022, compared to approximately $755,000 for the six months ended June 30, 2021. Compensation expense for the six months ended June 30, 2022 related to accelerated vesting of stock options for retirement eligible colleagues was immaterial. At June 30, 2022, the Corporation had approximately $855,000 of unrecognized compensation expense related to stock options that is expected to be recognized over the remaining requisite service periods that extend predominately through the first quarter of 2024. The Corporation also has issued time-based and performance-based restricted stock awards under the 2017 Incentive Compensation Plan and subsequent 2020 Incentive Compensation Plan. Performance awards are based on performance goals determined by the Corporation's Compensation and Benefits Committee, with vesting ranging from a minimum of 0% to a maximum of 150% of the target award. Performance awards are valued utilizing a Monte Carlo simulation model to estimate fair value of the awards at the grant date. The following table summarizes information about the Corporation’s restricted stock awards activity for the six months ended June 30, 2022: Restricted Stock Awards Shares (a) Weighted Average Outstanding at December 31, 2021 2,635 $ 19.87 Granted 673 23.44 Vested 754 23.16 Forfeited 22 21.35 Outstanding at June 30, 2022 2,532 $ 20.64 (a) In thousands The Corporation amortizes the expense related to restricted stock awards as compensation expense over the vesting period specified in the grant's award agreement.

The Board of Directors has authorized management to repurchase shares of the Corporation’s common stock in the market, to be made available for issuance in connection with the Corporation’s employee incentive plans and for other corporate purposes. The repurchase of shares, if any, will be based on market and investment opportunities, capital levels, growth prospects, and regulatory constraints. Such repurchases may occur from time to time in open market purchases, block transactions, private transactions, accelerated share repurchase programs, or similar facilities.

During the first quarter of 2021, the Corporation sold $51 million of lower yielding U.S. Treasury and Agency securities at an immaterial loss to take advantage of the steeper yield curve by reinvesting the proceeds into similar but higher yielding, longer duration securities. Investment securities with a carrying value of $2.6 billion and $2.3 billion at June 30, 2022 and December 31, 2021, respectively, were pledged to secure certain deposits or for other purposes. Accrued interest receivable on HTM securities totaled $18 million and $15 million at June 30, 2022 and December 31, 2021, respectively. Accrued interest receivable on AFS securities totaled $7 million and $9 million at June 30, 2022 and December 31, 2021, respectively. Accrued interest receivable on both HTM and AFS securities is included in interest receivable on the consolidated balance sheets. There was no interest income reversed for investments going into nonaccrual at both June 30, 2022 and 2021. A security is considered past due once it is 30 days past due under the terms of the agreement. At both June 30, 2022 and December 31, 2021, the Corporation had no past due HTM securities. The allowance for credit losses on HTM securities was approximately $63,000 at June 30, 2022 and approximately $55,000 at December 31, 2021, attributable entirely to the Corporation's municipal securities, included in HTM investment securities, net, at amortized cost on the consolidated balance sheets. The Corporation also holds U.S. Treasury, municipal and mortgage-related securities issued by the U.S. government or a GSE which are backed by the full faith and credit of the U.S. government and, as a result, no allowance for credit losses has been recorded related to these securities.

A determination as to whether a security’s decline in fair value is the result of credit risk takes into consideration numerous factors and the relative significance of any single factor can vary by security. Some factors the Corporation may consider in this impairment analysis include the extent to which the security has been in an unrealized loss position, the change in security rating, financial condition and near-term prospects of the issuer, as well as the security and industry specific economic conditions. Based on the Corporation’s evaluation, management does not believe any unrealized losses at June 30, 2022 represent credit deterioration as these unrealized losses are primarily attributable to changes in interest rates and the current market conditions. The Corporation does not intend to sell nor does it believe that it will be required to sell the securities in an unrealized loss position before recovery of their amortized cost basis. FHLB and Federal Reserve Bank stocks: The Corporation is required to maintain Federal Reserve Bank stock and FHLB stock as a member bank of both the Federal Reserve System and the FHLB, and in amounts as required by these institutions. These equity securities are “restricted” in that they can only be sold back to the respective institutions or another member institution at par. Therefore, they are less liquid than other marketable equity securities and their fair value is equal to amortized cost. The Corporation had FHLB stock of $151 million and $82 million at June 30, 2022 and December 31, 2021, respectively. The Corporation had Federal Reserve Bank stock of $87 million at both June 30, 2022 and December 31, 2021. Accrued interest receivable on FHLB stock totaled $1 million and approximately $975,000 at June 30, 2022 and December 31, 2021, respectively. There was no accrued interest receivable on Federal Reserve Bank stock at both June 30, 2022 and December 31, 2021. Accrued interest receivable on both FHLB stock and Federal Reserve Bank stock is included in interest receivable on the consolidated balance sheets. Equity Securities Equity securities with readily determinable fair values: The Corporation's portfolio of equity securities with readily determinable fair values is primarily comprised of CRA Qualified Investment mutual funds and other mutual funds. At June 30, 2022 and December 31, 2021, the Corporation had equity securities with readily determinable fair values of $6 million and $5 million, respectively.

(b) The Corporation’s policy is to assign risk ratings at the borrower level. PPP loans are 100% guaranteed by the SBA and therefore the Corporation considers these loans to have a risk profile similar to pass rated loans. (c) Includes asset-based lending & equipment finance. Factors that are important to managing overall credit quality are sound loan underwriting and administration, systematic monitoring of existing loans and commitments, effective loan review on an ongoing basis, early identification of potential problems, and appropriate policies for ACLL, nonaccrual loans, and charge offs. For commercial loans, management has determined the pass credit quality indicator to include credits exhibiting acceptable financial statements, cash flow, and leverage. If any risk exists, it is mitigated by the loan structure, collateral, monitoring, or control. For consumer loans, performing loans include credits performing in accordance with the original contractual terms. Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Special mention credits have potential weaknesses that warrant specific attention from management. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the credit. Accruing TDRs could be pass or special mention, depending on the risk rating on the loan. Potential problem loans are considered inadequately protected by the current net worth and paying capacity of the obligor or the collateral pledged. These loans generally have a well-defined weakness, or weaknesses, which may jeopardize liquidation of the debt, and are characterized by the distinct possibility the Corporation will sustain some loss if the deficiencies are not corrected. Management has determined commercial loan relationships in nonaccrual status, and commercial and consumer loan relationships with their terms restructured in a TDR, meet the criteria to be individually evaluated. Commercial loans classified as special mention, potential problem, and nonaccrual are reviewed at a minimum on a quarterly basis, while pass credits, which are performing rated credits, are generally reviewed on an annual basis or more frequently if the loan renewal is less than one year or if otherwise warranted.

Restructured loan modifications of consumer loans primarily included maturity date extensions, interest rate concessions, non-reaffirmed Chapter 7 bankruptcies, or a combination of these concessions for the six months ended June 30, 2022. The following table provides the number of loans modified in a TDR during the previous twelve months which subsequently defaulted during the six months ended June 30, 2022 and 2021, and the recorded investment in these restructured loans as of June 30, 2022 and 2021: Six Months Ended June 30, 2022 Six Months Ended June 30, 2021 ($ in Thousands) Number of Recorded Number of Recorded Residential mortgage 4 $ 1,178 1 $ 97 All loans modified in a TDR are individually evaluated for impairment. The nature and extent of the impairment of restructured loans, including those which have experienced a subsequent payment default, are considered in the determination of an appropriate level of the ACLL. The Corporation analyzes loans for classification as a probable TDR. This analysis includes identifying customers that are showing possible liquidity issues in the near term without reasonable access to alternative sources of capital. At June 30, 2022, the Corporation had no loans meeting this classification compared to $7 million at December 31, 2021. Allowance for Credit Losses on Loans The ACLL is comprised of the allowance for loan losses and the allowance for unfunded commitments. The level of the ACLL represents management’s estimate of an amount appropriate to provide for expected lifetime credit losses in the loan portfolio at the balance sheet date. The expected lifetime credit losses are the product of multiplying the Corporation's estimates of probability of default, loss given default, and the individual loan level exposure at default on an undiscounted basis. A main factor in the determination of the ACLL is the economic forecast. The Corporation utilized Moody's baseline forecast, updated during May 2022 and reviewed against the June 2022 forecast for material updates, in the allowance model. The forecast is applied over a 2 year reasonable and supportable period with straight-line reversion to the historical losses over the second year of the period. The allowance for unfunded commitments is maintained at a level believed by management to be sufficient to absorb expected lifetime losses related to unfunded credit facilities (including unfunded loan commitments and letters of credit). See Note 12 for additional information on the change in the allowance for unfunded commitments.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill Goodwill is not amortized but is instead subject to impairment tests on at least an annual basis, and more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Corporation conducted its most recent annual impairment testing in May 2022, utilizing a qualitative assessment. Factors that management considered in this assessment included macroeconomic conditions, industry and market considerations, overall financial performance of the Corporation and each reporting unit (both current and projected), changes in management strategy, and changes in the composition or carrying amount of net assets. In addition, management considered the changes in both the Corporation's common stock price and in the overall bank common stock index (based on the S&P 400 Regional Bank Sub-Industry Index), as well as the Corporation's earnings per common share trend over the past year. Based on these assessments, management concluded that it is more likely than not that the estimated fair value exceeded the carrying value (including goodwill) for each reporting unit. Therefore, a step one quantitative analysis was not required. There have been no events since the May 2022 impairment test that have changed the Corporation's impairment assessment conclusion. There were no impairment charges recorded in 2021 or the first six months of 2022. The Corporation had goodwill of $1.1 billion at both June 30, 2022 and December 31, 2021. Other Intangible Assets The Corporation has CDIs and historically had other intangible assets, both of which are amortized. For CDIs and other intangibles, changes in the gross carrying amount, accumulated amortization, and net book value were as follows: ($ in Thousands) Six Months Ended June 30, 2022 Year Ended Dec 31, 2021 Core deposit intangibles Gross carrying amount at the beginning of period $ 88,109 $ 88,109 Accumulated amortization (34,422) (30,016) Net book value $ 53,687 $ 58,093 Amortization during the period $ 4,405 $ 8,811 Other intangibles Gross carrying amount at the beginning of period $ — $ 2,000 Reductions due to sale — (1,317) Accumulated amortization — (683) Net book value $ — $ — Amortization during the period $ — $ 33 Mortgage Servicing Rights The Corporation sells residential mortgage loans in the secondary market and typically retains the right to service the loans sold. On January 1, 2022, the Corporation made the irrevocable election to account for its MSRs under the fair value measurement method, with any change in fair value being recognized through earnings in mortgage banking, net on the consolidated statements of income. MSRs are not traded in active markets. As a result, a cash flow model is used to determine fair value. Key assumptions and estimates, projected prepayment speeds, assumed servicing costs, ancillary income, costs to service delinquent loans, costs of foreclosure, and discount rates with option-adjusted spreads, are used in measuring the fair value of the MSRs asset. These assumptions are considered significant unobservable inputs. See Note 12 for a discussion of the recourse provisions on sold residential mortgage loans. See Note 13 which further discusses fair value measurement relative to the MSRs asset. A summary of changes in the balance of the MSRs asset under the fair value measurement method for the six months ended June 30, 2022 is as follows: ($ in Thousands) Six Months Ended June 30, 2022 Mortgage servicing rights Mortgage servicing rights at beginning of period $ 54,862 Cumulative effect of accounting methodology change 2,296 Balance at beginning of period, adjusted $ 57,158 Additions 5,231 Paydowns (5,220) Valuation: Change in fair value model assumptions 6,034 Changes in fair value of asset 13,366 Mortgage servicing rights at end of period $ 76,570 Portfolio of residential mortgage loans serviced for others (“servicing portfolio”) $ 6,910,382 Mortgage servicing rights to servicing portfolio 1.11 % Prior to January 1, 2022, the Corporation accounted for its MSRs under the amortization methodology. Under this methodology the Corporation evaluated its MSRs asset for impairment at minimum on a quarterly basis. Impairment was assessed based on fair value at each reporting date using estimated prepayment speeds of the underlying mortgage loans serviced and stratifications based on the risk characteristics of the underlying loans (predominantly loan type and note interest rate). As mortgage interest rates fell, prepayment speeds were usually faster and the value of the MSRs asset generally decreased, requiring additional valuation reserve. Conversely, as mortgage interest rates rose, prepayment speeds were usually slower and the value of the MSRs asset generally increased, requiring less valuation reserve. A valuation allowance was established, through a charge to earnings, to the extent the amortized cost of the MSRs exceeded the estimated fair value by stratification. An other-than-temporary impairment (i.e., recoverability was considered remote when considering interest rates and loan pay off activity) was recognized as a write-down of the MSRs asset and the related valuation allowance (to the extent a valuation allowance was available) and then against earnings. A direct write-down permanently reduced the carrying value of the MSRs asset and valuation allowance, precluding subsequent recoveries. A summary of changes in the balance of the MSRs asset and the MSRs valuation allowance under the amortization method for the year ended December 31, 2021 is as follows: ($ in Thousands) Year Ended Dec 31, 2021 Mortgage servicing rights Mortgage servicing rights at beginning of period $ 59,967 Additions 16,151 Amortization (19,436) Mortgage servicing rights at end of period $ 56,682 Valuation allowance at beginning of period $ (18,006) Recoveries, net 16,186 Valuation allowance at end of period $ (1,820) Mortgage servicing rights, net $ 54,862 Fair value of mortgage servicing rights $ 57,259 Portfolio of residential mortgage loans serviced for others (“servicing portfolio”) $ 6,994,834 Mortgage servicing rights, net to servicing portfolio 0.78 % Mortgage servicing rights expense (a) $ 3,250 (a) Includes the amortization of mortgage servicing rights and additions / recoveries to the valuation allowance of mortgage servicing rights, and is a component of mortgage banking, net on the consolidated statements of income. The projections of amortization expense for CDIs and decay for MSRs are based on existing asset balances, the current interest rate environment, and prepayment speeds as of June 30, 2022. The actual expense the Corporation recognizes in any given period may be significantly different depending upon acquisition or sale activities, changes in interest rates, prepayment speeds, market conditions, regulatory requirements, and events or circumstances that indicate the carrying amount of an asset may not be recoverable.

Under these arrangements, the Corporation may transfer legal control over the assets but still retain effective control through an agreement that both entitles and obligates the Corporation to repurchase the assets. The obligation to repurchase the securities is reflected as a liability on the Corporation’s consolidated balance sheets, while the securities underlying the repurchase agreements remain in the respective investment securities asset accounts (i.e., there is no offsetting or netting of the investment securities assets with the repurchase agreement liabilities). The Corporation utilizes securities sold under agreements to repurchase to facilitate the needs of its customers. The fair value of securities pledged to secure repurchase agreements may decline. At June 30, 2022, the Corporation had pledged securities valued at 133% of the gross outstanding balance of repurchase agreements to manage this risk. The remaining contractual maturity of the securities sold under agreements to repurchase on the consolidated balance sheets as of June 30, 2022 and December 31, 2021 are presented in the following table: Overnight and Continuous ($ in Thousands) Jun 30, 2022 Dec 31, 2021 Repurchase agreements Agency mortgage-related securities $ 273,659 $ 319,412 Long-Term Funding Subordinated Notes In November 2014, the Corporation issued $250 million of 10-year subordinated notes, due January 2025, and callable October 2024.

Derivative and Hedging Activities	Jun. 30, 2022
Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative and Hedging Activities	Derivative and Hedging Activities The Corporation is exposed to certain risk 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 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 receipts and its known or expected cash payments principally related to the Corporation's assets. The contract or notional amount of a derivative is used to determine, along with the other terms of the derivative, the amounts to be exchanged between the counterparties. The Corporation is exposed to credit risk in the event of nonperformance by counterparties to financial instruments. To mitigate the counterparty risk, contracts generally contain language outlining collateral pledging requirements for each counterparty. For non-centrally cleared derivatives, collateral must be posted when the market value exceeds certain mutually agreed upon threshold limits. Securities and cash are often pledged as collateral. The Corporation pledged $73 million and $71 million of investment securities as collateral at June 30, 2022 and December 31, 2021, respectively. At June 30, 2022, the Corporation posted immaterial required cash collateral compared to $11 million at December 31, 2021. Federal regulations require the Corporation to clear all LIBOR and compound SOFR interest rate swaps through a clearing house, if possible. For derivatives cleared through central clearing houses, the variation margin payments are legally characterized as daily settlements of the derivative rather than collateral. The Corporation's clearing agent for interest rate derivative contracts that are centrally cleared through the Chicago Mercantile Exchange (CME) and the London Clearing House (LCH) settles the variation margin daily. As a result, the variation margin payment and the related derivative instruments are considered a single unit of account for accounting and financial reporting purposes. Depending on the net position, the fair value is reported in other assets or accrued expenses and other liabilities on the consolidated balance sheets. The daily settlement of the derivative exposure does not change or reset the contractual terms of the instrument. Derivatives to Accommodate Customer Needs The Corporation facilitates customer borrowing activity by entering into various derivative contracts which are designated as free standing derivative contracts. Free standing derivative products are entered into primarily for the benefit of commercial customers seeking to manage their exposures to interest rate risk, foreign currency, and until early 2022, commodity prices. As of the end of the first quarter of 2022, the Corporation no longer had any outstanding commodity contracts. These derivative contracts are not designated against specific assets and liabilities on the consolidated balance sheets or forecasted transactions and, therefore, do not qualify for hedge accounting treatment. Such derivative contracts are carried at fair value in other assets and accrued expenses and other liabilities on the consolidated balance sheets with changes in the fair value recorded as a component of capital markets, net, and typically include interest rate-related instruments (swaps and caps), foreign currency exchange forwards, and until the end of the first quarter of 2022, commodity contracts. See Note 11 for additional information and disclosures on balance sheet offsetting. Interest rate-related instruments: The Corporation provides interest rate risk management services to commercial customers, primarily forward interest rate swaps and caps. The Corporation’s market risk from unfavorable movements in interest rates related to these derivative contracts is generally economically hedged by concurrently entering into offsetting derivative contracts. The offsetting derivative contracts have identical notional values, terms, and indices. Foreign currency exchange forwards: The Corporation provides foreign currency exchange services to customers, primarily forward contracts. The Corporation's customers enter into a foreign currency exchange forward with the Corporation as a means for them to mitigate exchange rate risk. The Corporation mitigates its risk by then entering into an offsetting foreign currency exchange derivative contract. Commodity contracts: As of the end of the first quarter of 2022, the Corporation no longer had any outstanding commodity contracts. Historically, commodity contracts were entered into primarily for the benefit of commercial customers seeking to manage their exposure to fluctuating commodity prices. The Corporation mitigated its risk by then entering into an offsetting commodity derivative contract. Mortgage Derivatives Interest rate lock commitments to originate residential mortgage loans held for sale and forward commitments on residential mortgage loans and TBA securities are considered derivative instruments, and the fair value of these commitments is recorded in other assets and accrued expenses and other liabilities on the consolidated balance sheets with the changes in fair value recorded as a component of mortgage banking, net on the consolidated statements of income. Interest rate-related instruments for MSRs hedge: The fair value of the Corporation's MSRs asset changes in response to changes in primary mortgage loan rates and other assumptions. To mitigate the earnings volatility caused by changes in the fair value of MSRs, the Corporation designates certain financial instruments as an economic hedge. Changes in the fair value of these instruments are generally expected to partially offset changes in the fair value of MSRs and are recorded in other assets and accrued expenses and other liabilities on the consolidated balance sheets with the changes in fair value recorded as a component of mortgage banking, net on the consolidated statements of income. The following table presents the total notional amounts and gross fair values of the Corporation’s derivatives, as well as the balance sheet netting adjustments as of June 30, 2022 and December 31, 2021. The derivative assets and liabilities are presented on a gross basis prior to the application of bilateral collateral and master netting agreements, but after the variation margin payments with central clearing organizations have been applied as settlement, as applicable. Total derivative assets and liabilities are adjusted to take into consideration the effects of legally enforceable master netting agreements and cash collateral received or paid as of June 30, 2022 and December 31, 2021. The resulting net derivative asset and liability fair values are included in other assets and accrued expenses and other liabilities, respectively, on the consolidated balance sheets.

Offsetting [Abstract]
Balance Sheet Offsetting	Balance Sheet Offsetting Interest Rate-Related Instruments, Commodity Contracts, and Foreign Exchange Forwards (“Interest, Commodity, and Foreign Exchange Agreements”) The Corporation enters into interest rate-related instruments to facilitate the interest rate risk management strategies of commercial customers and foreign exchange forwards to manage customers' exposure to fluctuating foreign exchange rates. The Corporation mitigates these risks by entering into equal and offsetting agreements with highly rated third-party financial institutions. Historically, the Corporation entered into commodity contracts to manage commercial customers' exposure to fluctuating commodity prices. As of the end of the first quarter of 2022, the Corporation no longer had any outstanding commodity contracts. The Corporation is party to master netting arrangements with its financial institution counterparties that create single net settlements of all legal claims or obligations to pay or receive the net amount of settlement of the individual interest and foreign exchange agreements. Collateral, usually in the form of investment securities and cash, is posted by the counterparty with net liability positions in accordance with contract thresholds. Derivatives subject to a legally enforceable master netting agreement are reported with assets and liabilities offset resulting in a net position which is further offset by any cash and investment securities collateral, and is reported in other assets and accrued expenses and other liabilities, on the face of the consolidated balance sheets. See Note 10 for additional information on the Corporation’s derivative and hedging activities. The following table presents the interest rate and foreign exchange assets and liabilities subject to an enforceable master netting arrangement as of June 30, 2022 and interest rate, commodity, and foreign exchange assets and liabilities subject to an enforceable master netting arrangement as of December 31, 2021. The interest and foreign exchange agreements the Corporation has with its commercial customers and the commodity agreements the Corporation had with its commercial customers are not subject to an enforceable master netting arrangement and are therefore excluded from this table: Gross Amounts Recognized Gross Amounts Subject to Master Netting Arrangements Offset on the Consolidated Balance Sheets Net Amounts Presented on the Consolidated Balance Sheets ($ in Thousands) Derivative Cash Collateral Received Derivative assets June 30, 2022 $ 27,214 $ (4,369) $ (22,756) $ 89 December 31, 2021 3,567 (2,143) (1,313) 111 Gross Amounts Recognized Gross Amounts Subject to Master Netting Arrangements Offset on the Consolidated Balance Sheets Net Amounts Presented on the Consolidated Balance Sheets ($ in Thousands) Derivative Cash Collateral Pledged Derivative liabilities June 30, 2022 $ 4,618 $ (4,369) $ — $ 249 December 31, 2021 15,620 (2,143) (11,357) 2,120

The following is a summary of lending-related commitments: ($ in Thousands) Jun 30, 2022 Dec 31, 2021 Commitments to extend credit, excluding commitments to originate residential mortgage loans held for sale (a)(b) $ 11,483,648 $ 10,848,136 Commercial letters of credit (a) 5,152 5,992 Standby letters of credit (c) 274,324 248,292 (a) These off-balance sheet financial instruments are exercisable at the market rate prevailing at the date the underlying transaction will be completed and, thus, are deemed to have no current fair value, or the fair value is based on fees currently charged to enter into similar agreements and was not material at June 30, 2022 or December 31, 2021. (b) Interest rate lock commitments to originate residential mortgage loans held for sale are considered derivative instruments and are disclosed in Note 10. (c) The Corporation has established a liability of $3 million and $2 million for June 30, 2022 and December 31, 2021, respectively, as an estimate of the fair value of these financial instruments. Lending-related Commitments As a financial services provider, the Corporation routinely enters into commitments to extend credit. Such commitments are subject to the same credit policies and approval process accorded to loans made by the Corporation, with each customer’s creditworthiness evaluated on a case-by-case basis. The commitments generally have fixed expiration dates or other termination clauses and may require the payment of a fee. The Corporation’s exposure to credit loss in the event of nonperformance by the other party to these financial instruments is represented by the contractual amount of those instruments. The amount of collateral obtained, if deemed necessary by the Corporation upon extension of credit, is based on management’s credit evaluation of the customer. Since a significant portion of commitments to extend credit are subject to specific restrictive loan covenants or may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash flow requirements. An allowance for unfunded commitments is maintained at a level believed by management to be sufficient to absorb expected lifetime losses related to unfunded commitments (including unfunded loan commitments and letters of credit). The following table presents a summary of the changes in the allowance for unfunded commitments: ($ in Thousands) Six Months Ended June 30, 2022 Year Ended December 31, 2021 Allowance for Unfunded Commitments Balance at beginning of period $ 39,776 $ 47,776 Provision for unfunded commitments (3,000) (8,000) Balance at end of period $ 36,776 $ 39,776 Lending-related commitments include commitments to extend credit, commitments to originate residential mortgage loans held for sale, commercial letters of credit, and standby letters of credit. Commitments to extend credit are legally binding agreements to lend to customers at predetermined interest rates, as long as there is no violation of any condition established in the contracts. Interest rate lock commitments to originate residential mortgage loans held for sale and forward commitments on residential mortgage loans and TBA securities are considered derivative instruments, and the fair value of these commitments is recorded in other assets and accrued expenses and other liabilities on the consolidated balance sheets. The Corporation’s derivative and hedging activity is further described in Note 10. Commercial and standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. Commercial letters of credit are issued specifically to facilitate commerce and typically result in the commitment being drawn on when the underlying transaction is consummated between the customer and the third party, while standby letters of credit generally are contingent upon the failure of the customer to perform according to the terms of the underlying contract with the third party. Other Commitments The Corporation invests in qualified affordable housing projects, historic projects, new market projects, and opportunity zone funds for the purpose of community reinvestment and obtaining tax credits and other tax benefits. Return on the Corporation's investment in these projects and funds comes in the form of the tax credits and tax losses that pass through to the Corporation, and deferral or elimination of capital gain recognition for tax purposes. The aggregate carrying value of these investments at June 30, 2022 was $250 million, compared to $268 million at December 31, 2021, included in tax credit and other investments on the consolidated balance sheets. The Corporation utilizes the proportional amortization method to account for investments in qualified affordable housing projects. Under the proportional amortization method, the Corporation amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits. The Corporation recognized additional income tax expense attributable to the amortization of investments in qualified affordable housing projects of $16 million for both the six months ended June 30, 2022 and June 30, 2021, and $8 million for both the three months ended June 30, 2022 and June 30, 2021. The Corporation's remaining investment in qualified affordable housing projects accounted for under the proportional amortization method totaled $245 million at June 30, 2022 and $262 million at December 31, 2021. The Corporation’s unfunded equity contributions relating to investments in qualified affordable housing and historic projects are recorded in accrued expenses and other liabilities on the consolidated balance sheets. The Corporation’s remaining unfunded equity contributions totaled $44 million at June 30, 2022 and $80 million at December 31, 2021. For the six months ended June 30, 2022 and the year ended December 31, 2021, the Corporation did not record any impairment related to qualified affordable housing investments. The Corporation has principal investment commitments to provide capital-based financing to private companies through either direct investment in specific companies or through investment funds and partnerships. The timing of future cash requirements to fund such principal investment commitments is generally dependent on the investment cycle, whereby privately held companies are funded by private equity investors and ultimately sold, merged, or taken public through an initial offering, which can vary based on overall market conditions, as well as the nature and type of industry in which the companies operate. The Corporation also invests in loan pools that support CRA loans. The timing of future cash requirements to fund these pools is dependent upon loan demand, which can vary over time. The aggregate carrying value of these investments was $25 million at both June 30, 2022 and December 31, 2021, included in tax credit and other investments on the consolidated balance sheets. Legal Proceedings The Corporation is party to various pending and threatened claims and legal proceedings arising in the normal course of business activities, some of which involve claims for substantial amounts. Although there can be no assurance as to the ultimate outcomes, the Corporation believes it has meritorious defenses to the claims asserted against it in its currently outstanding matters and intends to continue to defend itself vigorously with respect to such legal proceedings. The Corporation will consider settlement of cases when, in management’s judgment, it is in the best interests of the Corporation and its shareholders. On at least a quarterly basis, the Corporation assesses its liabilities and contingencies in connection with all pending or threatened claims and litigation, utilizing the most recent information available. On a matter by matter basis, an accrual for loss is established for those matters which the Corporation believes it is probable that a loss may be incurred and that the amount of such loss can be reasonably estimated. Once established, each accrual is adjusted as appropriate to reflect any subsequent developments. Accordingly, management’s estimate will change from time to time, and actual losses may be more or less than the current estimate. For matters where a loss is not probable, or the amount of the loss cannot be estimated, no accrual is established. Resolution of legal claims is inherently unpredictable, and in many legal proceedings various factors exacerbate this inherent unpredictability, including where the damages sought are unsubstantiated or indeterminate, it is unclear whether a case brought as a class action will be allowed to proceed on that basis, discovery is not complete, the proceeding is not yet in its final stages, the matters present legal uncertainties, there are significant facts in dispute, there are a large number of parties (including where it is uncertain how liability, if any, will be shared among multiple defendants), or there is a wide range of potential results. A lawsuit, Evans et al v. Associated Banc-Corp et al , was filed in the United States District Court for the Eastern District of Wisconsin - Green Bay Division on January 13, 2021 by one current and one former participant in the Associated Banc-Corp 401(k) and Employee Stock Ownership Plan (the “Plan”) as representatives of a putative class. The plaintiffs alleged that Associated Banc-Corp, the Associated Banc-Corp Plan Administrative Committee, and current and past members of such committee during the relevant time period (the “Defendants”) breached their fiduciary duties with respect to the Plan in violation of Employee Retirement Income Security Act of 1974, as amended, by applying an imprudent and inappropriate preference for products associated with Associated Banc-Corp within the Plan, and that the Defendants failed to monitor or control the recordkeeping expenses paid to Associated Trust Company, N.A. On March 18, 2021, the Defendants filed a motion to dismiss. On April 8, 2021, the plaintiffs filed an amended complaint which dropped the record keeping claim, added Associated Trust Company N.A. and Kellogg Asset Management, LLC as defendants, and alleged various breaches of fiduciary duty related to the selection and monitoring of, and the fees charged by, proprietary collective investment trusts. The plaintiffs, in part, seek an accounting and disgorgement of certain profits, as well as certain equitable restitution and equitable monetary relief. The Corporation intends to vigorously defend against this lawsuit. It is not possible for management to assess the probability of a material adverse outcome or reasonably estimate the amount of any potential loss at this time with respect to this lawsuit. Regulatory Matters A variety of consumer products, including mortgage and deposit products, and certain fees and charges related to such products, have come under increased regulatory scrutiny. It is possible that regulatory authorities could bring enforcement actions, including civil money penalties, or take other actions against the Corporation and the Bank in regard to these consumer products. The Bank could also determine of its own accord, or be required by regulators, to refund or otherwise make remediation payments to customers in connection with these products. It is not possible at this time for management to assess the probability of a material adverse outcome or reasonably estimate the amount of any potential loss related to such matters. Operational Matters In November 2021, we became aware that during several routine purges of old documents, certain documents that were more than seven years old relating to active accounts were inadvertently purged from our electronic database. The active account documents that were inadvertently purged related to (1) certain customer documents obtained as part of bank acquisitions, and (2) certain customer documents that were transferred to a new cold storage system without correct retention coding. Both the acquisitions and the transfer occurred years ago. The majority of the documents inadvertently purged were signature cards. We have undertaken measures to replace (if possible) or otherwise lessen the impact on customers of any inadvertently purged documents. While the impact on the Company of this incident has been immaterial to date, and we are not aware of any material adverse customer impact, it is not possible at this time for management to reasonably estimate the amount of any potential loss related to this incident. Mortgage Repurchase Reserve The Corporation sells residential mortgage loans to investors in the normal course of business. Residential mortgage loans sold to others are predominantly conventional residential first lien mortgages originated under the Corporation's usual underwriting procedures, and are most often sold on a nonrecourse basis, primarily to the GSEs. The Corporation’s agreements to sell residential mortgage loans in the normal course of business usually require certain representations and warranties on the underlying loans sold, related to credit information, loan documentation, collateral, and insurability. Subsequent to being sold, if a material underwriting deficiency or documentation defect is discovered, the Corporation may be obligated to repurchase the loan or reimburse the GSEs for losses incurred (collectively, “make whole requests”). The make whole requests and any related risk of loss under the representations and warranties are largely driven by borrower performance. Additionally, beginning in the third quarter of 2021, qualifying residential mortgage loans guaranteed by U.S. government agencies have been sold into GNMA pools. As a result of make whole requests, the Corporation has repurchased loans with aggregate principal balances of $3 million and $8 million for the six months ended June 30, 2022 and the year ended December 31, 2021, respectively. There were no loss reimbursement and settlement claims paid in the six months ended June 30, 2022, and approximately $114,000 of such claims were paid for the year ended December 31, 2021. Make whole requests during 2021 and the first six months of 2022 generally arose from loans originated during the period of January 1, 2017 to December 31, 2021. Since January 1, 2017, loans sold totaled $7.4 billion at the time of sale, and consisted primarily of loans sold to GSEs. As of June 30, 2022, $4.6 billion of loans originated since January 1, 2017 remain outstanding. The balance in the mortgage repurchase reserve at the balance sheet date reflects the estimated amount of potential loss the Corporation could incur from repurchasing a loan, as well as loss reimbursements, indemnifications, and other settlement resolutions. The mortgage repurchase reserve, included in accrued expenses and other liabilities on the consolidated balance sheets, was $1 million at both June 30, 2022 and December 31, 2021. The Corporation may also sell residential mortgage loans with limited recourse (limited in that the recourse period ends prior to the loan’s maturity, usually after certain time and / or loan paydown criteria have been met), whereby repurchase could be required if the loan had defined delinquency issues during the limited recourse periods. At June 30, 2022 and December 31, 2021, there were $7 million and $10 million, respectively, of residential mortgage loans sold with such recourse risk. There have been limited instances and immaterial historical losses on repurchases for recourse under the limited recourse criteria. The Corporation has a subordinate position to the FHLB in the credit risk on residential mortgage loans it sold to the FHLB in exchange for a monthly credit enhancement fee. The Corporation has not sold loans to the FHLB with such credit risk retention since February 2005. At June 30, 2022 and December 31, 2021, there were $22 million and $24 million, respectively, of such residential mortgage loans with credit risk recourse, upon which there have been immaterial historical losses to the Corporation.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value represents the estimated price at which an orderly transaction to sell an asset or to transfer a liability would take place between market participants at the measurement date under current market conditions (i.e., an exit price concept). The valuation methodologies for assets and liabilities measured at fair value on a recurring and non-recurring basis are described in the Fair Value Measurements note in the Corporation’s 2021 Annual Report on Form 10-K. There has been one significant change to the methodologies for assets and liabilities measured at fair value on a recurring basis: Mortgage Servicing Rights: The Corporation sells residential mortgage loans in the secondary market and typically retains the rights to service the loans sold. Upon sale, a MSRs asset is capitalized, which represents the then current fair value of future net cash flows expected to be realized for performing servicing activities. On January 1, 2022, the Corporation made the irrevocable election to account for its MSRs asset under the fair value measurement method. Under this methodology, changes in the fair value are recognized in earnings as they occur through mortgage banking, net on the consolidated statements of income. MSRs are not traded in active markets. A cash flow model is used to determine fair value. Key assumptions and estimates, including projected prepayment speeds, assumed servicing costs, ancillary income, costs to service delinquent loans, costs of foreclosure, and discount rates with option-adjusted spreads, used by this model are based on current market sources. Assumptions used to value MSRs are considered significant unobservable inputs. A separate third-party model is used to estimate prepayment speeds based on interest rates, housing turnover rates, estimated loan curtailment, anticipated defaults and other relevant factors. Fair value estimates from outside sources are received periodically to corroborate the results of the valuation model. Due to the nature of the valuation inputs, MSRs are classified within Level 3 of the fair value hierarchy. See Note 8 for additional disclosures about the Corporation's MSRs. The table below presents the Corporation’s financial instruments measured at fair value on a recurring basis as of June 30, 2022 and December 31, 2021, aggregated by the level in the fair value hierarchy within which those measurements fall: ($ in Thousands) Fair Value Hierarchy Jun 30, 2022 Dec 31, 2021 Assets AFS investment securities U.S. Treasury securities Level 1 $ 113,109 $ 122,957 Agency securities Level 2 13,959 14,897 Obligations of state and political subdivisions (municipal securities) Level 2 358,842 400,457 Residential mortgage-related securities FNMA / FHLMC Level 2 1,811,603 2,691,879 GNMA Level 2 86,238 67,780 Private-label Level 2 — 329,724 Commercial mortgage-related securities FNMA / FHLMC Level 2 18,606 350,623 GNMA Level 2 105,680 166,799 Asset backed securities FFELP Level 2 161,264 177,325 SBA Level 2 5,281 6,580 Other debt securities Level 2 2,929 2,994 Total AFS investment securities Level 1 $ 113,109 $ 122,957 Total AFS investment securities Level 2 2,564,402 4,209,058 Equity securities with readily determinable fair values Level 1 5,502 4,810 Residential loans held for sale Level 2 42,676 136,638 Mortgage servicing rights, net (a) Level 3 76,570 N/A Interest rate-related instruments (b) Level 2 34,184 83,626 Foreign currency exchange forwards (b) Level 2 4,190 5,490 Commodity contracts (b) Level 2 — 1,264 Interest rate lock commitments to originate residential mortgage loans held for sale Level 3 986 2,617 Forward commitments on residential mortgage loans Level 3 — 30 Forward commitments on TBA securities Level 3 47 — Liabilities Interest rate-related instruments (b) Level 2 $ 173,955 $ 26,231 Foreign currency exchange forwards (b) Level 2 3,764 5,441 Commodity contracts (b) Level 2 — 1,248 Forward commitments on residential mortgage loans Level 3 113 — (a) MSRs at December 31, 2021 were carried at LOCOM.

Retirement Benefits [Abstract]
Retirement Plans	Retirement Plans The Corporation has a noncontributory defined benefit RAP, covering substantially all employees who meet participation requirements. The benefits are based primarily on years of service and the employee’s compensation paid. Employees of acquired entities generally participate in the RAP after consummation of the business combinations. Any retirement plans of acquired entities are typically merged into the RAP after completion of the mergers, and credit is usually given to employees for years of service at the acquired institution for vesting and eligibility purposes. The Corporation also provides legacy healthcare access to a limited group of retired employees from a previous acquisition in the Postretirement Plan. There are no other active retiree healthcare plans. The components of net periodic pension cost and net periodic benefit cost for the RAP and Postretirement Plan for the three and six months ended June 30, 2022 and 2021 were as follows: Three Months Ended Jun 30, Six Months Ended Jun 30, ($ in Thousands) 2022 2021 2022 2021 Components of Net Periodic Benefit Cost RAP Service cost $ 923 $ 2,075 $ 1,847 $ 4,151 Interest cost 1,772 1,623 3,545 3,245 Expected return on plan assets (6,736) (6,430) (13,472) (12,861) Amortization of prior service cost (63) (18) (125) (37) Amortization of actuarial loss 74 1,050 147 2,100 Total net periodic pension cost $ (4,029) $ (1,701) $ (8,059) $ (3,402) Postretirement Plan Interest cost $ 13 $ 13 $ 27 $ 26 Amortization of prior service cost (19) (19) (38) (38) Total net periodic benefit cost $ (6) $ (6) $ (11) $ (12) The components of net periodic pension cost and net periodic benefit cost, other than the service cost component, are included in the line item other of noninterest expense on the consolidated statements of income. The service cost components are included in personnel on the consolidated statements of income. The Corporation’s funding policy is to pay at least the minimum amount required by federal law and regulations, with consideration given to the maximum funding amounts allowed. The Corporation regularly reviews the funding of its RAP. There were no contributions during the six months ended June 30, 2022 and 2021.

Segment Reporting

Segment Reporting	Jun. 30, 2022
Segment Reporting [Abstract]
Segment Reporting	Segment Reporting The Corporation utilizes a risk-based internal profitability measurement system to provide strategic business unit reporting. The profitability measurement system is based on internal management methodologies designed to produce consistent results and reflect the underlying economics of the units. Certain strategic business units have been combined for segment information reporting purposes where the nature of the products and services, the type of customer, and the distribution of those products and services are similar. The three reportable segments are Corporate and Commercial Specialty; Community, Consumer, and Business; and Risk Management and Shared Services. The financial information of the Corporation’s segments has been compiled utilizing the accounting policies described in the Corporation’s 2021 Annual Report on Form 10-K with certain exceptions. The more significant of these exceptions are described herein. The reportable segment results are presented based on the Corporation's internal management accounting process. The management accounting policies and processes utilized in compiling segment financial information are highly subjective and, unlike financial accounting, are not based on authoritative guidance similar to U.S. GAAP. As a result, reported segments and the financial information of the reported segments are not necessarily comparable with similar information reported by other financial institutions. Furthermore, changes in management structure or allocation methodologies and procedures may result in changes in previously reported segment financial data. Additionally, the information presented is not indicative of how the segments would perform if they operated as independent entities. To determine financial performance of each segment, the Corporation allocates FTP assignments, the provision for credit losses, certain noninterest expenses, income taxes, and equity to each segment. Allocation methodologies are subject to periodic adjustment as the internal management accounting system is revised, the interest rate environment evolves, and business or product lines within the segments change. Also, because the development and application of these methodologies is a dynamic process, the financial results presented may be periodically reviewed. The Corporation allocates net interest income using an internal FTP methodology that charges users of funds (assets, primarily loans) and credits providers of funds (liabilities, primarily deposits) based on the maturity, prepayment and / or re-pricing characteristics of the assets and liabilities. The net effect of this allocation is offset in the Risk Management and Shared Services segment to ensure consolidated totals reflect the Corporation's net interest income. The net FTP allocation is reflected as net intersegment interest income (expense) in the accompanying tables. The provision for credit losses is allocated to segments based on the expected long-term annual net charge off rates attributable to the credit risk of loans managed by the segment during the period. In contrast, the level of the consolidated provision for credit losses is determined based on an ACLL model using the methodologies described in the Corporation’s 2021 Annual Report on Form 10-K. The net effect of the credit provision is recorded in Risk Management and Shared Services. Indirect expenses incurred by certain centralized support areas are allocated to segments based on actual usage (for example, volume measurements) and other criteria. Certain types of administrative expense and bank-wide expense accruals (including amortization of CDIs and other intangible assets associated with acquisitions, acquisition-related costs, and asset gains on disposed business units) are generally not allocated to segments. Income taxes are allocated to segments based on the Corporation’s estimated effective tax rate, with certain segments adjusted for any tax-exempt income or non-deductible expenses. Equity is allocated to the segments based on regulatory capital requirements and in proportion to an assessment of the inherent risks associated with the business of the segment (including interest, credit and operating risk). A brief description of each business segment is presented below. A more in-depth discussion of these segments can be found in the Segment Reporting note in the Corporation’s 2021 Annual Report on Form 10-K. The Corporate and Commercial Specialty segment serves a wide range of customers including larger businesses, developers, not-for-profits, municipalities, and financial institutions by providing lending and deposit solutions as well as the support to deliver, fund, and manage such banking solutions. In addition, this segment provides a variety of investment, fiduciary, and retirement planning products and services to individuals and small to mid-sized businesses. During the first quarter of 2021, the Corporation sold its wealth management subsidiary Whitnell. The Community, Consumer, and Business segment serves individuals, as well as small and mid-sized businesses, by providing lending and deposit solutions. The Risk Management and Shared Services segment includes key shared operational functions and also includes residual revenue and expenses, representing the difference between actual amounts incurred and the amounts allocated to operating segments, including interest rate risk residuals (FTP mismatches) and credit risk and provision residuals (long-term credit charge mismatches). Effective during the first quarter of 2022, certain support functions and a select group of banking regions were realigned into the Community, Consumer, and Business segment from the Corporate and Commercial Specialty segment.

Revenue Recognition [Abstract]
Revenue from Contracts with Customers	Revenue from Contracts with Customers Revenue from contracts with customers is recognized when obligations under the terms of a contract with the Corporation's customer are satisfied. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. We do not have any material significant payment terms as payment is received at or shortly after the satisfaction of the performance obligation. The Corporation's disaggregated revenue by major source is presented below: Corporate and Commercial Specialty Three Months Ended Jun 30, Six Months Ended Jun 30, ($ in Thousands) 2022 2021 2022 2021 Wealth management fees $ 21,332 $ 22,706 $ 43,735 $ 45,120 Service charges and deposit account fees 3,724 3,859 7,508 7,800 Card-based fees (a) 327 295 744 640 Other revenue 658 1,151 1,893 1,814 Noninterest income (in-scope of Topic 606) $ 26,041 $ 28,010 $ 53,881 $ 55,375 Noninterest income (out-of-scope of Topic 606) (b) 13,092 9,271 23,042 23,734 Total noninterest income $ 39,133 $ 37,281 $ 76,923 $ 79,109 Community, Consumer, and Business Three Months Ended Jun 30, Six Months Ended Jun 30, ($ in Thousands) 2022 2021 2022 2021 Service charges and deposit account fees $ 12,777 $ 11,683 $ 25,846 $ 22,583 Card-based fees (a) 11,135 10,709 20,659 20,123 Other revenue 1,770 2,801 3,632 6,476 Noninterest income (in-scope of Topic 606) $ 25,683 $ 25,193 $ 50,138 $ 49,181 Noninterest income (out-of-scope of Topic 606) 6,438 7,774 15,189 31,116 Total noninterest income $ 32,121 $ 32,967 $ 65,327 $ 80,298 Risk Management and Shared Services Three Months Ended Jun 30, Six Months Ended Jun 30, ($ in Thousands) 2022 2021 2022 2021 Service charges and deposit account fees $ 5 $ 7 $ 8 $ 22 Card-based fees (a) 10 5 17 9 Other revenue (120) 307 (81) 697 Noninterest income (in-scope of Topic 606) $ (105) $ 319 $ (56) $ 728 Noninterest income (out-of-scope of Topic 606) 4,310 2,876 7,731 8,651 Total noninterest income $ 4,204 $ 3,195 $ 7,675 $ 9,379 Consolidated Total Three Months Ended Jun 30, Six Months Ended Jun 30, ($ in Thousands) 2022 2021 2022 2021 Wealth management fees $ 21,332 $ 22,706 $ 43,735 $ 45,120 Service charges and deposit account fees 16,506 15,549 33,363 30,404 Card-based fees (a) 11,472 11,009 21,421 20,773 Other revenue 2,309 4,258 5,444 8,987 Noninterest income (in-scope of Topic 606) $ 51,619 $ 53,522 $ 103,963 $ 105,284 Noninterest income (out-of-scope of Topic 606) (b) 23,840 19,921 45,962 63,502 Total noninterest income $ 75,458 $ 73,443 $ 149,925 $ 168,786 (a) Certain card-based fees are out-of-scope of Topic 606. (b) For the six months ended June 30, 2021, the Corporation recognized a $2 million pre-tax gain on the sale of Whitnell. Below is a listing of performance obligations for the Corporation's main revenue streams: Revenue Stream Noninterest income in-scope of Topic 606 Service charges and deposit account fees Service charges and deposit account fees consist of monthly service fees (i.e. business analyzed fees and consumer service charges) and other deposit account related fees. The Corporation's performance obligation for monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Other deposit account related fees are largely transactional based, and therefore, the Corporation's performance obligation is satisfied, and related revenue recognized, at a point in time. Payment for service charges and deposit account fees is primarily received immediately or in the following month through a direct charge to customers’ accounts. Card-based fees (a) Card-based fees are primarily comprised of debit and credit card income, ATM fees, and merchant services income. Debit and credit card income is primarily comprised of interchange fees earned whenever the Corporation's debit and credit cards are processed through card payment networks. ATM and merchant fees are largely transactional based, and therefore, the Corporation's performance obligation is satisfied, and related revenue recognized, at a point in time. Payment is typically received immediately or in the following month. Trust and asset management fees (b) Trust and asset management income is primarily comprised of fees earned from the management and administration of trusts and other customer assets. The Corporation's performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the month-end market value of the assets under management and the applicable fee rate. Payment is generally received a few days after month end through a direct charge to the customers’ accounts. The Corporation's performance obligation for these transactional-based services is generally satisfied, and related revenue recognized, at a point in time (i.e., as incurred). Payment is received shortly after services are rendered. Brokerage and advisory fees (b) Brokerage and advisory fees primarily consist of investment advisory, brokerage, retirement services, and annuities. The Corporation's performance obligation for investment advisory services and retirement services is generally satisfied, and the related revenue recognized, over the period in which the services are provided. The performance obligation for annuities is satisfied upon sale of the annuity, and therefore, the related revenue is primarily recognized at the time of sale. Payment for these services are typically received immediately or in advance of the service. (a) Certain card-based fees are out-of-scope of Topic 606. (b) Trust and asset management fees and brokerage and advisory fees are included in wealth management fees.

Leases [Abstract]
Leases	Leases The Corporation has operating leases for retail and corporate offices, land, and equipment. The Corporation also has a finance lease for retail and corporate offices. These leases have original terms of 1 year or longer with remaining maturities up to 40 years, some of which include options to extend the lease term. An analysis of the lease options has been completed and any purchase options or optional periods that the Corporation is reasonably likely to extend have been included in the capitalization. The discount rate used to capitalize the operating leases is the Corporation's FHLB borrowing rate on the date of lease commencement. When determining the rate to discount specific lease obligations, the repayment period and term are considered. Operating and finance lease costs and cash flows resulting from these leases are presented below: Three Months Ended Jun 30, Six Months Ended Jun 30, ($ in Thousands) 2022 2021 2022 2021 Operating lease costs $ 1,926 $ 2,243 $ 3,724 $ 4,483 Finance lease costs 32 19 73 58 Operating lease cash flows 2,327 2,777 4,735 5,740 Finance lease cash flows 37 40 80 80 The lease classifications on the consolidated balance sheets were as follows: ($ in Thousands) Consolidated Balance Sheets Category Jun 30, 2022 Dec 31, 2021 Operating lease right-of-use asset Premises and equipment $ 26,621 $ 28,299 Finance lease right-of-use asset Other assets 498 143 Operating lease liability Accrued expenses and other liabilities 29,627 31,345 Finance lease liability Other long-term funding 511 163 The lease payment obligations, weighted-average remaining lease term, and weighted-average original discount rate were as follows: Jun 30, 2022 Dec 31, 2021 ($ in Thousands) Lease payments Weighted-average lease term (in years) Weighted-average discount rate Lease payments Weighted-average lease term (in years) Weighted-average discount rate Operating leases Equipment $ 191 1.00 0.44 % $ 192 1.50 0.45 % Retail and corporate offices 26,553 5.71 2.28 % 29,008 5.56 3.26 % Land 5,160 7.93 3.13 % 5,551 8.29 3.12 % Total operating leases $ 31,904 6.02 2.41 % $ 34,751 5.94 3.22 % Finance leases Retail and corporate offices $ 530 5.75 1.32 % $ 112 1.25 1.32 % Land — 0.00 — % 51 0.67 1.07 % Total finance leases $ 530 5.75 1.32 % $ 164 1.07 1.24 % Contractual lease payment obligations for each of the next five years and thereafter, in addition to a reconciliation to the Corporation’s lease liability, were as follows: ($ in Thousands) Operating Leases Finance Leases Total Leases Six months ended December 31, 2022 $ 3,515 $ 45 $ 3,560 2023 6,240 92 6,332 2024 5,650 93 5,742 2025 4,387 93 4,479 2026 3,823 93 3,915 Beyond 2026 8,290 116 8,406 Total lease payments $ 31,904 $ 530 $ 32,434 Less: interest 2,276 19 2,296 Present value of lease payments $ 29,627 $ 511 $ 30,138

Under this methodology the Corporation evaluated its MSRs asset for impairment at minimum on a quarterly basis. Impairment was assessed based on fair value at each reporting date using estimated prepayment speeds of the underlying mortgage loans serviced and stratifications based on the risk characteristics of the underlying loans (predominantly loan type and note interest rate). As mortgage interest rates fell, prepayment speeds were usually faster and the value of the MSRs asset generally decreased, requiring additional valuation reserve. Conversely, as mortgage interest rates rose, prepayment speeds were usually slower and the value of the MSRs asset generally increased, requiring less valuation reserve. A valuation allowance was established, through a charge to earnings, to the extent the amortized cost of the MSRs exceeded the estimated fair value by stratification. An other-than-temporary impairment (i.e., recoverability was considered remote when considering interest rates and loan pay off activity) was recognized as a write-down of the MSRs asset and the related valuation allowance (to the extent a valuation allowance was available) and then against earnings. A direct write-down permanently reduced the carrying value of the MSRs asset and valuation allowance, precluding subsequent recoveries. A summary of changes in the balance of the MSRs asset and the MSRs valuation allowance under the amortization method for the year ended December 31, 2021 is as follows: ($ in Thousands) Year Ended Dec 31, 2021 Mortgage servicing rights Mortgage servicing rights at beginning of period $ 59,967 Additions 16,151 Amortization (19,436) Mortgage servicing rights at end of period $ 56,682 Valuation allowance at beginning of period $ (18,006) Recoveries, net 16,186 Valuation allowance at end of period $ (1,820) Mortgage servicing rights, net $ 54,862 Fair value of mortgage servicing rights $ 57,259 Portfolio of residential mortgage loans serviced for others (“servicing portfolio”) $ 6,994,834 Mortgage servicing rights, net to servicing portfolio 0.78 % Mortgage servicing rights expense (a) $ 3,250

Revenue recognition 606	Below is a listing of performance obligations for the Corporation's main revenue streams: Revenue Stream Noninterest income in-scope of Topic 606 Service charges and deposit account fees Service charges and deposit account fees consist of monthly service fees (i.e. business analyzed fees and consumer service charges) and other deposit account related fees. The Corporation's performance obligation for monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Other deposit account related fees are largely transactional based, and therefore, the Corporation's performance obligation is satisfied, and related revenue recognized, at a point in time. Payment for service charges and deposit account fees is primarily received immediately or in the following month through a direct charge to customers’ accounts. Card-based fees (a) Card-based fees are primarily comprised of debit and credit card income, ATM fees, and merchant services income. Debit and credit card income is primarily comprised of interchange fees earned whenever the Corporation's debit and credit cards are processed through card payment networks. ATM and merchant fees are largely transactional based, and therefore, the Corporation's performance obligation is satisfied, and related revenue recognized, at a point in time. Payment is typically received immediately or in the following month. Trust and asset management fees (b) Trust and asset management income is primarily comprised of fees earned from the management and administration of trusts and other customer assets. The Corporation's performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the month-end market value of the assets under management and the applicable fee rate. Payment is generally received a few days after month end through a direct charge to the customers’ accounts. The Corporation's performance obligation for these transactional-based services is generally satisfied, and related revenue recognized, at a point in time (i.e., as incurred). Payment is received shortly after services are rendered. Brokerage and advisory fees (b) Brokerage and advisory fees primarily consist of investment advisory, brokerage, retirement services, and annuities. The Corporation's performance obligation for investment advisory services and retirement services is generally satisfied, and the related revenue recognized, over the period in which the services are provided. The performance obligation for annuities is satisfied upon sale of the annuity, and therefore, the related revenue is primarily recognized at the time of sale. Payment for these services are typically received immediately or in advance of the service. (a) Certain card-based fees are out-of-scope of Topic 606. (b) Trust and asset management fees and brokerage and advisory fees are included in wealth management fees.

RAP
Net period benefit cost for the pension and postretirement plans
Defined Benefit Plan, Description			The Corporation has a noncontributory defined benefit RAP, covering substantially all employees who meet participation requirements. The benefits are based primarily on years of service and the employee’s compensation paid. Employees of acquired entities generally participate in the RAP after consummation of the business combinations. Any retirement plans of acquired entities are typically merged into the RAP after completion of the mergers, and credit is usually given to employees for years of service at the acquired institution for vesting and eligibility purposes.
