Notes to Consolidated Financial Statements

These interim consolidated financial statements have been prepared according to the rules and regulations of the SEC and, therefore, certain information and footnote disclosures normally presented in accordance with GAAP have been omitted or abbreviated. The information contained on the consolidated financial statements and footnotes in Associated Banc-Corp's 2020 Annual Report on Form 10-K should be referred to in connection with the reading of these unaudited interim consolidated financial statements.

Note 1 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, goodwill impairment assessment, MSRs valuation, and income taxes. 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.

Note 2 Acquisitions and Dispositions

Acquisitions:

The Corporation has not had any acquisitions during the first nine months of 2021.

2020

First Staunton Acquisition

On February 14, 2020, the Corporation completed its acquisition of First Staunton. The purchase price was based on an assumed 4% deposit premium at announcement. The conversion of the branches was completed simultaneously with the close of the transaction, expanding the Bank's presence into nine new Metro-East St. Louis communities. As a result of the acquisition and other consolidations, a net of seven branch locations were added.

The Corporation recorded $15 million in goodwill related to the First Staunton acquisition. Goodwill created by the acquisition is not tax deductible.

For a description of methods used to determine the fair value of significant assets and liabilities presented on the balance sheet above, see Assumptions section of this Note.

The Corporation has purchased loans with the First Staunton acquisition, for which there was, at acquisition, evidence of more than insignificant deterioration of credit quality since origination (PCD). The carrying amount of those loans is as follows:

($ in Thousands)	February 14, 2020
Purchase price of loans at acquisition	$	77,221
Allowance for credit losses at acquisition	3,504
Non-credit discount/(premium) at acquisition	(951)
Par value of acquired loans at acquisition	$	79,774

The Corporation acquired no PCD securities in connection with the acquisition.

Assumptions

Investment Securities: The fair value of investments on the date of acquisition was determined utilizing an external third party broker opinion of the market value.

Loans: Fair values for loans were based on a discounted cash flow methodology that considered factors including the type of loan and related collateral, classification status, fixed or variable interest rate, term of loan, amortization status and current discount rates. For the non-credit (interest and liquidity) premium, loans were grouped together according to similar characteristics when applying various valuation techniques. For the credit discount, loans were also grouped based on whether they had more than insignificant deterioration in credit since origination.

CDIs: This intangible asset represents the value of the relationships with deposit customers. The fair value was estimated based on a discounted cash flow methodology that gave appropriate consideration to expected customer attrition rates, net maintenance cost of the deposit base, alternative cost of funds, and the interest costs associated with customer deposits. The CDIs are being amortized on a straight-line basis over 10 years.

Time Deposits: The fair value for time deposits are estimated using a discounted cash flow calculation that applies interest rates currently being offered to the contractual interest rates on such time deposits.

FHLB Borrowings: The fair value of FHLB advances is estimated based on quoted market prices for the instrument if available, or for similar instruments if not available, or by using discounted cash flow analyses, based on current incremental borrowing rates for similar types of instruments.

Dispositions:

2021

On February 26, 2021, the Bank completed the sale of one branch located in Monroe, Wisconsin to Summit Credit Union. Under the terms of the transaction, Associated Bank sold $31 million in total deposits and no loans. Associated Bank received an approximately 4% purchase premium on deposits transferred.

Note 4 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:

Diluted earnings per common share	$	0.56	$	0.26	$	1.69	$	1.46

Non-dilutive common stock options of approximately 3 million and 8 million for the three months ended September 30, 2021 and 2020, respectively, and 3 million and 7 million for the nine months ended September 30, 2021 and 2020, respectively, were excluded from the earnings per common share calculation.

Note 5 Stock-Based Compensation

The fair values of stock options and restricted stock awards (including restricted stock units) 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.

Assumptions are used in estimating the fair value of stock options granted. The weighted average expected life of the stock option represents the period of time stock options are expected to be outstanding and is estimated using historical data of stock option exercises and forfeitures. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. The expected volatility is based on the implied volatility of the Corporation’s stock.

15

The Corporation did not grant stock options in the first nine months of 2021. The following assumptions were used in estimating the fair value for options granted for the full year 2020:

	2020
Dividend yield	3.50	%
Risk-free interest rate	1.60	%
Weighted average expected volatility	21.00	%
Weighted average expected life	5.75 years
Weighted average per share fair value of options	$2.39

A summary of the Corporation’s stock option activity for the nine months ended September 30, 2021 is presented below:

Stock Options	Shares(a)	Weighted Average Exercise Price		Weighted Average Remaining Contractual Term	Aggregate Intrinsic Value(a)
Outstanding at December 31, 2020	6,473	$	19.77	6.23 years	$	2,005
Exercised	1,116	16.36
Forfeited or expired	97	22.61
Outstanding at September 30, 2021	5,260	$	20.44	6.01 years	$	11,044
Options Exercisable at September 30, 2021	3,694	$	20.58	5.19 years	$	8,062

(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 nine months ended September 30, 2021, the intrinsic value of stock options exercised was $6 million compared to less than $1 million for the nine months ended September 30, 2020. For the nine months ended September 30, 2021, the total fair value of stock options vested was $3 million compared to $4 million for the nine months ended September 30, 2020.

The Corporation recognized compensation expense for the vesting of stock options of $1 million for the nine months ended September 30, 2021, compared to $3 million for the nine months ended September 30, 2020. Included in compensation expense for 2021 was approximately $65,000 for the accelerated vesting of stock options granted to retirement eligible colleagues. At September 30, 2021, the Corporation had $2 million 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 of earnings per share and total shareholder return 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 nine months ended September 30, 2021:

Restricted Stock Awards	Shares(a)	Weighted Average Grant Date Fair Value
Outstanding at December 31, 2020	2,293	$	20.70
Granted	1,212	20.00
Vested	797	21.23
Forfeited	52	22.39
Outstanding at September 30, 2021	2,656	$	19.86

(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. Performance-based restricted stock awards granted during 2020 and 2021 will cliff-vest after the three year performance period has ended. Service-based restricted stock awards granted during 2020 and 2021 will vest ratably over a period of four years. Expense for restricted stock awards issued of $11 million was recorded for the nine months ended September 30, 2021 and $15 million was recorded for the nine months ended September 30, 2020. Included in compensation expense for the first nine months of 2021 was $2 million of expense for the accelerated vesting of restricted stock awards granted to retirement eligible colleagues. The Corporation had $24 million of unrecognized compensation costs related to restricted stock awards at September 30, 2021 that are expected to be recognized over the remaining requisite service periods that extend predominately through the first quarter of 2025.

16

The Corporation has the ability to issue shares from treasury or new shares upon the exercise of stock options or the granting of restricted stock awards. 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 second quarter of 2021, the Corporation sold $107 million of lower yielding FFELP student loan asset backed securities at a slight gain and reinvested the proceeds into higher yielding mortgage backed securities. During the first quarter of 2021, the Corporation sold $51 million of lower yielding U.S. Treasury and Agency securities at a slight loss to take advantage of the steeper yield curve by reinvesting the proceeds into similar but higher yielding, longer duration securities.

During the second quarter of 2020, the Corporation sold $261 million of less liquid securities at a gain of $3 million, reinvesting the proceeds into more liquid securities in order to further improve portfolio liquidity. During the first quarter of 2020, the Corporation sold $281 million of primarily prepayment sensitive mortgage-related securities at a gain of $6 million. Additionally, in February 2020, the Corporation sold $84 million of certain securities acquired in the First Staunton acquisition that did not fit the parameters of the Corporation's current investment strategy.

Investment securities with a carrying value of $2.2 billion and $1.6 billion at September 30, 2021 and December 31, 2020, respectively, were pledged to secure certain deposits or for other purposes as required or permitted by law.

Accrued interest receivable on HTM securities totaled $12 million and $14 million at September 30, 2021 and December 31, 2020, respectively. Accrued interest receivable on AFS securities totaled $9 million and $8 million at September 30, 2021 and December 31, 2020, 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 September 30, 2021 and 2020.

A security is considered past due once it is 30 days past due under the terms of the agreement. At both September 30, 2021 and December 31, 2020, the Corporation had no past due HTM securities.

The allowance for credit losses on HTM securities was approximately $49,000 at September 30, 2021 and approximately $67,000 at December 31, 2020, attributable entirely to the Corporation's municipal securities, included in investment securities HTM, 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.

The Corporation reviews the AFS investment securities portfolio on a quarterly basis to monitor its credit exposure. 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

20

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 September 30, 2021 represent credit deterioration as these unrealized losses are primarily attributable to changes in interest rates and the current market conditions. The U.S. Treasury 3 year and 5 year rates increased by 36 bp and 62 bp, respectively, from December 31, 2020. 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 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 $82 million at both September 30, 2021 and December 31, 2020. The Corporation had Federal Reserve Bank stock of $87 million at both September 30, 2021 and December 31, 2020. Accrued interest receivable on FHLB stock totaled approximately $974,000 and $972,000 at September 30, 2021 and December 31, 2020, respectively. There was $327,000 accrued interest receivable on Federal Reserve Bank stock at September 30, 2021 and none at December 31, 2020. 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 a money market mutual fund. At September 30, 2021 and December 31, 2020, the Corporation had equity securities with readily determinable fair values of $4 million and $2 million, respectively.

Equity securities without readily determinable fair values: The Corporation's portfolio of equity securities without readily determinable fair values primarily consists of 77,996 Visa Class B restricted shares, 77,000 of which the Corporation received in 2008 as part of Visa's initial public offering and carried at fair value after the Corporation donated 42,039 Visa Class B restricted shares to the Corporation's Charitable Remainder Trust during the second quarter of 2019, with the subsequent sale of those shares resulting in an observable market price after the shares were previously carried at a zero cost basis. During the first quarter of 2020, the Corporation acquired 996 Visa Class B restricted shares from the acquisition of First Staunton, and those shares are carried at a zero cost basis due to the lack of an observable market price since the time of acquisition. The Corporation had equity securities without readily determinable fair values of $14 million at September 30, 2021 and $13 million at December 31, 2020.

(a) Revolving loans converted to term loans are also reported in their year of origination.

(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) Accruing TDRs are included in pass unless otherwise rated as special mention.

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 allowance for loan losses, allowance for unfunded commitments, 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.

26

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. 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.

(a) Nonaccrual restructured loans have been included within nonaccrual loans.
(b) Does not include any restructured loans related to the COVID-19 pandemic in accordance with Section 4013 of the CARES Act.

The Corporation had a recorded investment of $14 million in loans modified as TDRs during the nine months ended September 30, 2021, of which $7 million were in accrual status, included in pass or special mention based on their risk rating within the credit quality tables, and $7 million were in nonaccrual within the credit quality tables, pending a sustained period of repayment. Short-term loan modifications made in good faith to help ease the adverse effects of the COVID-19 pandemic are not categorized as TDRs in accordance with the CARES Act. The following table provides the number of loans modified in a TDR by loan portfolio, the recorded investment, and unpaid principal balance for the nine months ended September 30, 2021 and 2020:

	Nine months ended Sep 30, 2021					Nine months ended Sep 30, 2020

(a) Represents post-modification outstanding recorded investment.
(b) Represents pre-modification outstanding recorded investment.

Restructured loan modifications may include payment schedule modifications, interest rate concessions, maturity date extensions, modification of note structure (A/B Note), non-reaffirmed Chapter 7 bankruptcies, principal reduction, or some combination of these concessions. During the nine months ended September 30, 2021, restructured loan modifications of commercial loans primarily included maturity date extensions and payment schedule modifications. 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 nine months ended September 30, 2021.

The following table provides the number of loans modified in a TDR during the previous twelve months which subsequently defaulted during the nine months ended September 30, 2021 and 2020, and the recorded investment in these restructured loans as of September 30, 2021 and 2020:

	Nine months ended Sep 30, 2021			Nine months ended Sep 30, 2020
($ in Thousands)	Number of Loans	Recorded Investment		Number of Loans	Recorded Investment
Residential mortgage	2	$	200	5	$	1,036
Home equity	—	—		4	208
Total loans modified	2	$	200	9	$	1,244

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 September 30, 2021, the Corporation had $17 million in loans meeting this classification compared to $68 million at December 31, 2020. Of the loans classified as probable TDRs at September 30, 2021, the entire $17 million was related to the oil and gas portfolio.

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 September 2021, 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.

Loans Acquired in Acquisitions

Loans acquired in a business combination after January 1, 2020 are recorded in accordance with ASC Topic 326. See Note 2 for more information on loans acquired in a business combination. After January 1, 2020, acquired loans were segregated into two types:

•Non-PCD loans are accounted for in accordance with ASC Topic 310-20 "Nonrefundable Fees and Other Costs" as these loans do not show evidence of credit deterioration since origination. The allowance for loan losses on these loans is recorded through provision for credit losses on the consolidated statements of income at acquisition.

•PCD loans are loans demonstrating more than insignificant credit deterioration and are accounted for in accordance with ASC Topic 326-30. Under this guidance, the credit mark on acquired assets grosses up the ACLL and the amortized cost of the loan.

Note 8 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 2021, 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 2021 impairment test that have changed the Corporation's impairment assessment conclusion. There were no impairment charges recorded in 2020 or the first nine months of 2021.

At both September 30, 2021 and December 31, 2020, the Corporation had goodwill of $1.1 billion. During the first quarter of 2021, there was a reduction of $4 million of goodwill related to the sale of Whitnell.

Other Intangible Assets

The Corporation has other intangible assets that are amortized, consisting of CDIs and MSRs. For CDIs and other intangibles, changes in the gross carrying amount, accumulated amortization, and net book value were as follows:

($ in Thousands)	Nine months ended Sep 30, 2021		Year Ended Dec 31, 2020
Core deposit intangibles
Gross carrying amount at the beginning of period	$	88,109	$	80,730

Accumulated amortization	(683)		(20,385)
Net book value	$	—	$	1,350
Amortization during the period	$	33	$	1,443

Mortgage Servicing Rights

The Corporation sells residential mortgage loans in the secondary market and typically retains the right to service the loans sold. MSRs are amortized in proportion to and over the period of estimated net servicing income and assessed for impairment at each reporting date.

32

The Corporation evaluates its MSRs asset for impairment at minimum on a quarterly basis. Impairment is 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 fall, prepayment speeds are usually faster and the value of the MSRs asset generally decreases, requiring additional valuation reserve. Conversely, as mortgage interest rates rise, prepayment speeds are usually slower and the value of the MSRs asset generally increases, requiring less valuation reserve. A valuation allowance is established, through a charge to earnings, to the extent the amortized cost of the MSRs exceeds the estimated fair value by stratification. An other-than-temporary impairment (i.e., recoverability is considered remote when considering interest rates and loan pay off activity) is recognized as a write-down of the MSRs asset and the related valuation allowance (to the extent a valuation allowance is available) and then against earnings. A direct write-down permanently reduces the carrying value of the MSRs asset and valuation allowance, precluding subsequent recoveries. 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 and the MSRs valuation allowance is as follows:

($ in Thousands)	Nine months ended Sep 30, 2021			Year Ended Dec 31, 2020
Mortgage servicing rights
Mortgage servicing rights at beginning of period	$	59,967		$	67,607

(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 are based on existing asset balances, the current interest rate environment, and prepayment speeds as of September 30, 2021. The actual amortization 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. The following table shows the estimated future amortization expense for amortizing intangible assets:

($ in Thousands)	Core Deposit Intangibles		Mortgage Servicing Rights

Securities Sold Under Agreements to Repurchase

The Corporation enters into agreements under which it sells securities subject to an obligation to repurchase the same or similar securities. 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. As of September 30, 2021, the Corporation pledged agency mortgage-related securities with a fair value of $364 million as collateral for the repurchase agreements. Securities pledged as collateral under repurchase agreements are maintained with the Corporation's safekeeping agents and are monitored on a daily basis due to the market risk of fair value changes in the underlying securities. The Corporation generally pledges excess securities to ensure there is sufficient collateral to satisfy short-term fluctuations in both the repurchase agreement balances and the fair value of the underlying securities.

The remaining contractual maturity of the securities sold under agreements to repurchase on the consolidated balance sheets as of September 30, 2021 and December 31, 2020 are presented in the following table:

	Remaining Contractual Maturity of the Agreements
($ in Thousands)	Overnight and Continuous		Up to 30 days		30-90 days		Greater than 90 days		Total

Long-Term Funding

Senior Notes 

In August 2018, the Bank issued $300 million of senior notes, due August 2021, and callable July 2021. The senior notes had a fixed coupon interest rate of 3.50% and were issued at a discount. The Bank redeemed all of the senior notes on July 13, 2021, the initial redemption date under the terms of the notes.

34

Subordinated Notes 

In November 2014, the Corporation issued $250 million of 10-year subordinated notes, due January 2025, and callable October 2024. The subordinated notes have a fixed coupon interest rate of 4.25% and were issued at a discount.

Finance Leases

In connection with the construction of a new branch in Oshkosh, Wisconsin, the Corporation entered into a land lease with the option to purchase the underlying land for a fixed price, which the Corporation now expects to exercise. The finance lease has a fixed interest rate of 1.07%. See Note 18 for additional disclosure regarding the Corporation’s leases.

Note 10 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 $78 million and $72 million of investment securities as collateral at September 30, 2021, and December 31, 2020, respectively. At September 30, 2021, the Corporation posted $18 million of cash collateral compared to $31 million at December 31, 2020.

Federal regulations require the Corporation to clear all LIBOR 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 commodity prices. 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 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

35

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: Commodity contracts are entered into primarily for the benefit of commercial customers seeking to manage their exposure to fluctuating commodity prices. The Corporation mitigates 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 to sell residential mortgage loans 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.

The following table presents the total notional amounts and gross fair values of the Company’s derivatives, as well as the balance sheet netting adjustments as of September 30, 2021 and December 31, 2020. 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 September 30, 2021 and December 31, 2020. 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.

The Corporation terminated its $500 million fair value hedge during the fourth quarter of 2019. At September 30, 2021, the amortized cost basis of the closed portfolios which had previously been used in the terminated hedging relationship was $446 million and is included in loans on the consolidated balance sheets. This amount includes $2 million of hedging adjustments on the discontinued hedging relationships.

Note 11 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, commodity contracts to manage commercial customers' exposure to fluctuating commodity prices, 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. 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, commodity, 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 on a net basis, net of cash collateral, 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, commodity, and foreign exchange assets and liabilities subject to an enforceable master netting arrangement. The interest, commodity and foreign exchange agreements the Corporation has with its commercial customers are not subject to an enforceable master netting arrangement and are therefore excluded from this table:

Note 12 Commitments, Off-Balance Sheet Arrangements, Legal Proceedings and Regulatory Matters

The Corporation utilizes a variety of financial instruments in the normal course of business to meet the financial needs of its customers and to manage its own exposure to fluctuations in interest rates. These financial instruments include lending-related and other commitments (see below) as well as derivative instruments (see Note 10). The following is a summary of lending-related commitments:

($ in Thousands)	Sep 30, 2021		Dec 31, 2020
Commitments to extend credit, excluding commitments to originate residential mortgage loans held for sale(a)(b)	$	10,618,161	$	10,010,492
Commercial letters of credit(a)	6,309		3,642
Standby letters of credit(c)	264,123		278,798

(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 September 30, 2021 or December 31, 2020.
(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 for both September 30, 2021 and December 31, 2020, as an estimate of the fair value of these financial instruments.

38

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)	Nine months ended Sep 30, 2021		Year Ended Dec 31, 2020
Allowance for Unfunded Commitments
Balance at beginning of period	$	47,776	$	21,907
Cumulative effect of ASU 2016-13 adoption (CECL)	N/A		18,690
Balance at beginning of period, adjusted	47,776		40,597
Provision for unfunded commitments	(6,500)		7,000
Amount recorded at acquisition	N/A		179
Balance at end of period	$	41,276	$	47,776

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 to sell residential mortgage loans 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, federal and state 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 September 30, 2021 was $277 million, compared to $272 million at December 31, 2020, 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 $24 million and $18 million for the nine months ended September 30, 2021 and 2020, respectively, and $8 million and $6 million for the three months ended September 30, 2021 and 2020, respectively. The Corporation's remaining investment in qualified affordable housing projects accounted for under the proportional amortization method totaled $270 million at September 30, 2021 and $268 million at December 31, 2020.

The Corporation’s unfunded equity contributions relating to investments in federal and state qualified affordable housing and federal and state historic projects are recorded in accrued expenses and other liabilities on the consolidated balance sheets. The Corporation’s remaining unfunded equity contributions totaled $101 million and $118 million at September 30, 2021 and December 31, 2020, respectively.

For the nine months ended September 30, 2021 and the year ended December 31, 2020, 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 and public 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 $24 million and $25 million at September 30, 2021 and December 31, 2020, respectively, 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.

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

40

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 $6 million and $10 million for the nine months ended September 30, 2021 and the year ended December 31, 2020, respectively. There were approximately $114,000 of loss reimbursement and settlement claims paid for the nine months ended September 30, 2021 and there were no such claims for the year ended December 31, 2020. Make whole requests during 2020 and the first nine months of 2021 generally arose from loans sold during the period of January 1, 2012 to December 31, 2020. Since January 1, 2012, loans sold totaled $15.7 billion at the time of sale, and consisted primarily of loans sold to GSEs. As of September 30, 2021, $6.5 billion of these sold loans 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 as of September 30, 2021 and $2 million as of December 31, 2020.

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 September 30, 2021 and December 31, 2020, there were $27 million and $36 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 September 30, 2021 and December 31, 2020, there were $26 million and $33 million, respectively, of such residential mortgage loans with credit risk recourse, upon which there have been negligible historical losses to the Corporation.

Note 13 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 2020 Annual Report on Form 10-K.

Note 14 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 First Staunton acquisition closed on February 14, 2020, and the employees who met the required criteria became eligible to participate in the RAP on February 15, 2020, with their vesting service credit based on their prior hours of service with First Staunton. See Note 2 for additional information on the First Staunton acquisition.

The components of net periodic pension cost and net periodic benefit cost for the RAP and Postretirement Plan for the three and nine months ended September 30, 2021 and 2020 were as follows:

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 nine months ended September 30, 2021 and 2020.

Note 15 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 2020 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) 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.

A 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 2020 Annual Report on

45

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 2020 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. In addition, until June 30, 2020, the Corporation offered insurance and risk consulting services. 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).

Note 17 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.

49

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.

Note 18 Leases

The Corporation has operating leases for retail and corporate offices, land, and equipment. The Corporation also has a finance lease for land.

These leases have original terms of 1 year or longer with remaining maturities up to 41 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:

Overview

The following discussion and analysis is presented to assist in the understanding and evaluation of the Corporation’s financial condition and results of operations. It is intended to complement the unaudited consolidated financial statements, footnotes, and supplemental financial data appearing elsewhere in this Quarterly Report on Form 10-Q and should be read in conjunction therewith. Management continually evaluates strategic acquisition opportunities and various other strategic alternatives that could involve the sale or acquisition of branches or other assets, or the consolidation or creation of subsidiaries. Within the tables presented, certain columns and rows may not sum due to the use of rounded numbers for disclosure purposes.

On September 9, 2021, the Corporation presented a new growth focused and digital forward strategic vision which included taking the following actions or committing to future actions:

Expanding our Lending Capabilities:

•Diversifying our consumer portfolio by growing auto finance

•Broadening current asset-based lending capabilities

•Launching equipment finance vertical in our commercial business

Growing our Core Businesses:

•Accelerating core commercial middle market lending growth

•Enhancing small business, consumer direct and home equity line of credit lending

•Retooling our mass affluent strategy

Investing in our Digital Transformation:

•Redirecting $50 million of investment over the next five years to digital with incremental costs expected to be funded by the annual run-rate savings from the planned branch consolidations, back-office facilities consolidations, and the transformation of legacy IT infrastructure

•Preparing to deploy new mobile and online systems in the next six months

•Transforming our legacy IT infrastructure to deliver greater differentiation

52

Optimizing Capital Proactively:

•Optimizing tangible common equity to accelerate return on average tangible common equity expansion

•Paying a dividend commensurate with performance

•Reducing our preferred capital layers

Performance Summary

•Average loans of $24.1 billion decreased $343 million, or 1%, compared to the first nine months of 2020. The Corporation expects 2021 commercial loan growth, excluding PPP, of approximately 2%.

•Average deposits of $27.5 billion increased $1.7 billion, or 7%, from the first nine months of 2020, driven primarily by government stimulus related inflows and changing savings habits by customers in response to the pandemic.

•Net interest income of $539 million decreased $36 million, or 6%, from the first nine months of 2020, and net interest margin was 2.38% compared to 2.54% for the first nine months of 2020. Both decreases were primarily due to a lower interest rate environment. The Corporation expects a full year margin of approximately 2.40%.

•Provision for credit losses had a release of $82 million, compared to provision expense of $157 million for the first nine months of 2020. The Corporation expects fourth quarter provision to adjust with changes to risk grade, economic conditions, other indications of credit quality, and loan volume.

•Noninterest income of $251 million decreased $177 million, or 41%, from the first nine months of 2020, primarily driven by the $163 million gain on the sale of ABRC in 2020 and the resulting reduction in related insurance revenues. The Corporation expects 2021 noninterest income to be at the upper end of the $315 million to $325 million range.

•Noninterest expense of $528 million decreased $75 million, or 13%, from the first nine months of 2020, primarily due to a $45 million loss on prepayment of FHLB advances incurred during 2020 and a decrease in personnel expense of $15 million, or 5%, from 2020 which was primarily due to having fewer employees partially offset by an increase in funding for the management incentive plan. The Corporation expects 2021 noninterest expense of approximately $705 million to $711 million, including initiatives and proposed facilities exit costs.

Notable Contributions to the Change in Net Interest Income

•Net interest income on the consolidated statements of income (which excludes the fully tax-equivalent adjustment) was $539 million for the first nine months of 2021 compared to $575 million for the first nine months of 2020. Fully tax-equivalent net interest income of $551 million for the first nine months of 2021 was $36 million, or 6%, lower than the first nine months of 2020. The net interest margin for the first nine months of 2021 was 2.38% compared to 2.54% for the first nine months of 2020. The decreases were attributable to a lower interest rate environment and increased liquidity being held in lower yielding interest-bearing deposits in other financial institutions. See sections Interest Rate Risk and Quantitative and Qualitative Disclosures about Market Risk for a discussion of interest rate risk and market risk.

•    Average interest-bearing liabilities of $21.8 billion for the first nine months of 2021 were down $1.5 billion, or 7%, compared to the first nine months of 2020. On average, FHLB advances decreased $1.2 billion, or 43%, primarily driven by the Corporation's prepayment of $950 million in FHLB advances during the third quarter of 2020. Interest-bearing deposits increased $349 million, or 2%, primarily driven by an increase in low cost deposits partially offset by decreases in higher cost deposits. Average noninterest-bearing demand deposits of $8.0 billion for the first nine months of 2021 were up $1.3 billion, or 20%, versus the first nine months of 2020.

•    The cost of interest-bearing liabilities was 0.35% for the first nine months of 2021, which was a 37 bp drop from the first nine months of 2020, primarily attributable to the federal funds rate decreases which occurred in March 2020.

•The Federal Reserve lowered the federal funds target interest to a range of 0.00% to 0.25% in March 2020, which has remained constant through the end of the third quarter of 2021.

Provision for Credit Losses

The provision for credit losses is predominantly a function of the Corporation’s reserving methodology and judgments as to other qualitative and quantitative factors used to determine the appropriate level of the ACLL, which focuses on changes in the size and character of the loan portfolio, changes in levels of individually evaluated and other nonaccrual loans, historical losses and delinquencies in each portfolio category, the risk inherent in specific loans, concentrations of loans to specific borrowers or industries, existing economic conditions and economic forecasts, the fair value of underlying collateral, and other factors which could affect potential credit losses. The forecast the Corporation used for September 30, 2021 was the Moody's baseline scenario from September 2021 over a 2 year reasonable and supportable period with straight-line reversion to historical losses over the second year of the period. See additional discussion under the sections titled, Loans, Credit Risk, Nonperforming Assets, and Allowance for Credit Losses on Loans.

Notable Contributions to the Change in Noninterest Income

•Mortgage banking, net increased $12 million from the first nine months of 2020 due to a $12 million recovery of MSRs impairment during 2021 as a result of market rates recovering, compared to impairment of $18 million during the first nine months of 2020 offset by decreased gains on sold loans due to lower mortgage settlements as well as contracting margins on the loans sold.

•Asset gains (losses), net decreased $147 million from the first nine months of 2020, driven by a gain of $163 million from the sale of ABRC during the second quarter of 2020, offset by a gain of $2 million from the sale of Whitnell and higher gains from private equity investments during the first nine months of 2021.

•Insurance commissions and fees decreased $45 million from the first nine months of 2020, driven by the sale of ABRC during the second quarter of 2020 which largely eliminated the source of noninterest income.

•Service charges and deposit account fees increased $6 million from the first nine months of 2020 as a result of service charges that were waived during 2020 in response to the COVID-19 pandemic.

Notable Contributions to the Change in Noninterest Expense

•Personnel expense decreased $15 million from the first nine months of 2020, primarily due to having fewer employees as a result of the sales of ABRC and Whitnell, corporate restructurings, and branch sales, partially offset by an increase in funding for the management incentive plan.

•Business development and advertising expenses increased $3 million in the first nine months of 2021 as travel and advertising activity has resumed and begun to normalize from the pandemic lows.

•During the third quarter of 2020, the Corporation prepaid $950 million of long-term FHLB advances and incurred a loss of $45 million on the prepayment.

Income Taxes

The Corporation recognized income tax expense of $70 million for the nine months ended September 30, 2021, compared to income tax expense of $3 million for the nine months ended September 30, 2020. The Corporation's effective tax rate was 20.37% for the first nine months of 2021, compared to an effective tax rate of 1.37% for the first nine months of 2020. The increases in the effective tax rate and income tax expense during the first nine months of 2021 were primarily driven by tax planning strategies which occurred during the third quarter of 2020. The Corporation expects a full year effective tax rate of 19% to 21%, assuming no change in the statutory corporate tax rate.

Income tax expense recorded on the consolidated statements of income involves the interpretation and application of certain accounting pronouncements and federal and state tax laws and regulations, and is, therefore, considered a critical accounting policy. The Corporation is subject to examination by various taxing authorities. Examination by taxing authorities may impact the amount of tax expense and / or reserve for uncertainty in income taxes if their interpretations differ from those of management, based on their judgments about information available to them at the time of their examinations. See section Critical Accounting Policies, in the Corporation’s 2020 Annual Report on Form 10-K for additional information on income taxes.

The Corporation has long-term guidelines relative to the proportion of Commercial and Business, CRE, and Consumer loan commitments within the overall loan portfolio, with each targeted to represent 30 to 40% of the overall loan portfolio. The targeted long-term guidelines were unchanged during 2020 and the first nine months of 2021. Furthermore, certain sub-asset classes within the respective portfolios are further defined and dollar limitations are placed on these sub-portfolios. These guidelines and limits are reviewed quarterly and approved annually by the Enterprise Risk Committee of the Corporation’s Board of Directors. These guidelines and limits are designed to create balance and diversification within the loan portfolios.

Credit Risk

An active credit risk management process is used for commercial loans to ensure that sound and consistent credit decisions are made. Credit risk is controlled by detailed underwriting procedures, comprehensive loan administration, and periodic review of borrowers’ outstanding loans and commitments. Borrower relationships are formally reviewed and graded on an ongoing basis for early identification of potential problems. Further analysis by customer, industry, and geographic location are performed to monitor trends, financial performance, and concentrations. See Note 7 Loans of the notes to consolidated financial statements for additional information on managing overall credit quality.

The loan portfolio is widely diversified by types of borrowers, industry groups, and market areas within the Corporation's branch footprint. Significant loan concentrations are considered to exist when there are amounts loaned to numerous borrowers engaged in similar activities that would cause them to be similarly impacted by economic or other conditions. At September 30, 2021, no significant concentrations existed in the Corporation’s portfolio in excess of 10% of total loans.

Commercial and business lending: The commercial and business lending classification primarily includes commercial loans to large corporations, middle market companies, small businesses, and lease financing.

Table 7 Largest Commercial and Business Lending Industry Group Exposures

September 30, 2021	% of Total Loans		% of Total Commercial and Business Lending
Utilities	7	%	19	%
Finance and Insurance	7	%	18	%
Manufacturing and Wholesale Trade	7	%	18	%
Real Estate	6	%	15	%

The remaining commercial and business lending portfolio is spread over a diverse range of industries, none of which exceed 2% of total loans.

The credit risk related to commercial loans is largely influenced by general economic conditions and the resulting impact on a borrower’s operations or on the value of underlying collateral, if any.

60

Commercial real estate - investor: CRE-investor is comprised of loans secured by various non-owner occupied or investor income producing property types.

Table 8 Largest Commercial Real Estate Investor Property Type Exposures

September 30, 2021	% of Total Loans		% of Total Commercial Real Estate - Investor
Multi-Family	6	%	32	%
Office	4	%	23	%
Industrial	3	%	18	%
Retail	3	%	17	%

The remaining CRE-investor portfolio is spread over various other property types, none of which exceed 2% of total loans.

Credit risk is managed in a similar manner to commercial and business lending by employing sound underwriting guidelines, lending primarily to borrowers in local markets and businesses, periodically evaluating the underlying collateral, and formally reviewing the borrower’s financial soundness and relationship on an ongoing basis.

Real estate construction: Real estate construction loans are primarily short-term or interim loans that provide financing for the acquisition or development of commercial income properties, multi-family projects, or residential development, both single family and condominium. Real estate construction loans are made to developers and project managers who are generally well known to the Corporation and have prior successful project experience. The credit risk associated with real estate construction loans is generally confined to specific geographic areas but is also influenced by general economic conditions. The Corporation controls the credit risk on these types of loans by making loans in familiar markets to developers, reviewing the merits of individual projects, controlling loan structure, and monitoring project progress and construction advances.

Table 9 Largest Real Estate Construction Property Type Exposures

September 30, 2021	% of Total Loans		% of Total Real Estate Construction
Multi-Family	3	%	32	%

The remaining real estate construction portfolio is spread over various other property types, none of which exceed 2% of total loans.

The Corporation’s current lending standards for CRE and real estate construction lending are determined by property type and specifically address many criteria, including: maximum loan amounts, maximum LTV, requirements for pre-leasing and / or presales, minimum borrower equity, and maximum loan-to-cost. Currently, the maximum standard for LTV is 80%, with lower limits established for certain higher risk types, such as raw land that has a 50% LTV maximum. The Corporation’s LTV guidelines are in compliance with regulatory supervisory limits. In most cases, for real estate construction loans, the loan amounts include interest reserves, which are built into the loans and sized to fund loan payments through construction and lease up and / or sell out.

Residential mortgages: Residential mortgage loans are primarily first lien home mortgages with a maximum loan-to-collateral value without credit enhancement (e.g. private mortgage insurance) of 80%. The residential mortgage portfolio is focused primarily in the Corporation's three-state branch footprint, with approximately 87% of the outstanding loan balances in the Corporation's branch footprint at September 30, 2021. The majority of the on balance sheet residential mortgage portfolio consists of LIBOR or constant maturity treasury based, hybrid, adjustable rate mortgage loans with initial fixed rate terms of 3, 5, 7, or 10 years. The rates on these mortgages adjust based upon the movement in the underlying index which is then added to a margin and rounded to the nearest 0.125%. That result is then subjected to any periodic caps to produce the borrower's interest rate for the coming term.

In 2014, the Financial Stability Oversight Council and Financial Stability Board raised concerns about the reliability and robustness of LIBOR and called for the development of alternative interest rate benchmarks. The ARRC, through authority from the Federal Reserve, have selected the SOFR as the alternative rate and developed a paced transition plan which addresses the risk that LIBOR may not exist beyond the end of 2021. There are still many components of this plan which have not been fully decided or implemented in the industry. As a result, the Corporation is reaching out to certain borrowers offering an opportunity to refinance or modify their loans to avoid any uncertainty around the LIBOR transition. Performing borrowers can modify or refinance to a fixed interest rate or an adjustable rate mortgage tied to the one-year treasury adjusted to a constant maturity of one-year with an appropriate margin. This provides the Bank and borrower with greater certainty around the loan structure. The Bank has not booked a LIBOR adjustable rate mortgage since the first quarter of 2020.

61

The Corporation generally retains certain fixed-rate residential real estate mortgages in its loan portfolio, including retail and private banking jumbo mortgages and CRA-related mortgages. As part of management’s historical practice of originating and servicing residential mortgage loans, generally the Corporation’s 30 year, agency conforming, fixed-rate residential real estate mortgage loans have been sold in the secondary market with servicing rights retained. Subject to management’s analysis of the current interest rate environment, among other market factors, the Corporation may choose to retain 30 year mortgage loan production on its balance sheet. See section Loans for additional information on loans.

The Corporation’s underwriting and risk-based pricing guidelines for residential mortgage loans include minimum borrower FICO and maximum LTV of the property securing the loan. Residential mortgage products generally are underwritten using FHLMC and FNMA secondary marketing guidelines.

Home equity: Home equity consists of both home equity lines of credit and closed-end home equity loans. The Corporation’s credit risk monitoring guidelines for home equity is based on an ongoing review of loan delinquency status, as well as a quarterly review of FICO score deterioration and property devaluation. The Corporation does not routinely obtain appraisals on performing loans to update LTV ratios after origination; however, the Corporation monitors the local housing markets by reviewing the various home price indices and incorporates the impact of the changing market conditions in its ongoing credit monitoring process. For junior lien home equity loans, the Corporation is unable to track the performance of the first lien loan if it does not own or service the first lien loan. However, the Corporation obtains a refreshed FICO score on a quarterly basis and monitors this as part of its assessment of the home equity portfolio.

The Corporation’s underwriting and risk-based pricing guidelines for home equity lines of credit and loans consist of a combination of both borrower FICO and the original cumulative LTV against the property securing the loan. Currently, the Corporation's policy sets the maximum acceptable LTV at 90% and the minimum acceptable FICO at 670. The Corporation's current home equity line of credit offering is priced based on floating rate indices and generally allows 10 years of interest-only payments followed by a 20-year amortization of the outstanding balance. The loans in the Corporation's portfolio generally have an original term of 20 years with principal and interest payments required. See section Loans for additional information on loans.

Other consumer: Other consumer consists of student loans, short-term personal installment loans, and credit cards. The Corporation had $107 million and $118 million of student loans at September 30, 2021 and December 31, 2020, respectively, the majority of which are government guaranteed. As a result of the COVID-19 pandemic and the passage of the CARES Act, and subsequent executive orders, the federal student loan relief was extended through January 31, 2022. Credit risk for non-government guaranteed student loans, short-term personal installment loans, and credit cards is influenced by general economic conditions, the characteristics of individual borrowers, and the nature of the loan collateral. Risks of loss are generally on smaller average balances per loan spread over many borrowers. Once charged off, there is usually less opportunity for recovery of these smaller consumer loans. Credit risk is primarily controlled by reviewing the creditworthiness of the borrowers, monitoring payment histories, and taking appropriate collateral and guarantee positions. The student loan portfolio is in run-off and no new student loans are being originated.

SBA Loans under the PPP:

The Corporation began submitting PPP forgiveness applications on behalf of our customers on September 14, 2020. On December 27, 2020, the Economic Aid Act was signed into law, which included another round of PPP funding. The Corporation began originating the new round of PPP loans in January 2021 until the statutory end of the program in May 2021.

The following table summarizes the balance segmentation of the PPP loans and associated deferred fees as of September 30, 2021:

(a) 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.

Nonaccrual loans: Nonaccrual loans are considered to be one indicator of potential future loan losses. See Note 7 Loans of the notes to consolidated financial statements for additional nonaccrual loan disclosures. See also sections Credit Risk and Allowance for Credit Losses on Loans.

Accruing loans past due 90 days or more: Loans past due 90 days or more but still accruing interest are classified as such where the underlying loans are both well secured (the collateral value is sufficient to cover principal and accrued interest) and are in the process of collection.

Restructured loans: Loans are considered restructured loans if concessions have been granted to borrowers that are experiencing financial difficulty. See also Note 7 Loans of the notes to consolidated financial statements for additional restructured loans disclosures.

Potential problem loans: The level of potential problem loans is another predominant factor in determining the relative level of risk in the loan portfolio and in determining the appropriate level of the ACLL. Potential problem loans are generally defined by management to include loans rated as substandard by management that are collectively evaluated (not nonaccrual loans or accruing TDRs); however, there are circumstances present to create doubt as to the ability of the borrower to comply with present repayment terms. The decision of management to include performing loans in potential problem loans does not necessarily mean that the Corporation expects losses to occur, but that management recognizes a higher degree of risk associated with these loans.

OREO: Management actively seeks to ensure OREO properties held are monitored to minimize the Corporation’s risk of loss.

Other nonperforming assets: During 2020, the Corporation wrote off the ownership interest in an oil and gas limited liability company it had received in partial settlement of a debt.

Allowance for Credit Losses on Loans

Credit risks within the loan portfolio are inherently different for each loan type. Credit risk is controlled and monitored through the use of lending standards, a thorough review of potential borrowers, and ongoing review of loan payment performance. Active asset quality administration, including early problem loan identification and timely resolution of problems, aids in the management of credit risk and the minimization of loan losses. Credit risk management for each loan type is discussed in the section entitled Credit Risk. See Note 7 Loans of the notes to consolidated financial statements for additional disclosures on the ACLL.

To assess the appropriateness of the ACLL, the Corporation focuses on the evaluation of many factors, including but not limited to: evaluation of facts and issues related to specific loans, management’s ongoing review and grading of the loan portfolio, credit report refreshes, consideration of historical loan loss and delinquency experience on each portfolio category, trends in past due and nonaccrual loans, the level of potential problem loans, the risk characteristics of the various classifications of loan segments, changes in the size and character of the loan portfolio, concentrations of loans to specific borrowers or industries, existing economic conditions and economic forecasts, the fair value of underlying collateral, funding assumptions on lines, and other qualitative and quantitative factors which could affect potential credit losses. The Corporation utilized the Moody's baseline forecast for September 2021 in the allowance model. The forecast is applied over a 2 year reasonable and supportable period with straight-line reversion to historical losses over the second year of the period. Assessing these factors involves significant judgment. Because each of the criteria used is subject to change, the ACLL is not necessarily indicative of the trend of future credit losses on loans in any particular segment. Therefore, management considers the ACLL a critical accounting policy, see section Critical Accounting Policies for additional information on the ACLL. See section Nonperforming Assets for a detailed discussion on asset quality. See also Note 7 Loans of the notes to consolidated financial statements for additional ACLL disclosures. Table 5 provides information on loan growth and period end loan composition, Table 11 provides additional information regarding NPAs, and Table 12 and Table 13 provide additional information regarding activity in the ACLL.

The loan segmentation used in calculating the ACLL at September 30, 2021 and December 31, 2020 was generally comparable. The methodology to calculate the ACLL consists of the following components: a valuation allowance estimate is established for commercial and consumer loans determined by the Corporation to be individually evaluated, using discounted cash flows, estimated fair value of underlying collateral, and/or other data available. Loans are segmented for criticized loan pools by loan type as well as for non-criticized loan pools by loan type, primarily based on historical loss rates after considering loan type, historical loss and delinquency experience, credit quality, and industry classifications. Loans that have been criticized are considered to have a higher risk of default than non-criticized loans, as circumstances were present to support the lower loan grade, warranting higher loss factors. The loss factors applied in the methodology are periodically re-evaluated and adjusted to reflect changes in historical loss levels or other risks. Additionally, management allocates ACLL to absorb losses that may not be provided for by the other components due to qualitative factors evaluated by management, such as limitations within the credit risk grading process, known current economic or business conditions that may not yet show in trends, industry or other concentrations with current issues that impose higher inherent risks than are reflected in the loss factors, and other relevant considerations. The total allowance is available to absorb losses from any segment of the loan portfolio.

Notable Contributions to the Change in the Allowance for Credit Losses on Loans

•Potential problem loans decreased $31 million, or 11%, from December 31, 2020, and decreased $42 million, or 14%, from September 30, 2020. The decrease from December 31, 2020 was primarily driven by PPP loans, as they have been forgiven, along with a decrease in CRE-investor lending. The decrease from September 30, 2020 was primarily driven by decreases in CRE-investor, commercial and industrial lending, and PPP loans. These decreases were partially offset by an increase in real estate construction. See Table 11 for additional information regarding potential problem loans.

•Total nonaccrual loans decreased $76 million, or 36%, from December 31, 2020, and decreased $97 million, or 42%, from September 30, 2020. The decrease from December 31, 2020 was primarily due to decreases in commercial and industrial lending along with CRE-investor lending. The decrease from September 30, 2020 was primarily driven by a decrease in commercial and industrial lending. As economic conditions trended downward in 2020, due to the COVID-19 pandemic, nonaccrual loans increased. As economic conditions have been improving throughout 2021, nonaccrual loans have decreased. See Note 7 Loans of the notes to consolidated financial statements and Table 11 for additional disclosures on the changes in asset quality.

•YTD net charge offs decreased $56 million, or 76%, from September 30, 2020, primarily driven by decreased charge off amounts in commercial and industrial loans, partially offset by higher charge off amounts in CRE-investor lending due to COVID-19 related impacts in that industry. See Table 12 and Table 13 for additional information on the activity in the ACLL.

Management believes the level of ACLL to be appropriate at September 30, 2021.

•Total deposits, which are the Corporation's largest source of funds, increased $1.4 billion, or 5%, from December 31, 2020, and increased $1.1 billion, or 4%, from September 30, 2020, as government stimulus related inflows and customer savings habits have changed in response to the pandemic.

•Time deposits decreased $346 million, or 20%, from December 31, 2020, and decreased $616 million, or 30%, from September 30, 2020, due to higher priced time deposits rolling off as they mature.

•Included in the above amounts were $929 million of network deposits, primarily sourced from other financial institutions and intermediaries. These represented 3% of the Corporation's total deposits at September 30, 2021. Network deposits decreased $268 million, or 22%, from December 31, 2020, and decreased $462 million, or 33%, from September 30, 2020.

Liquidity

The objective of liquidity risk management is to ensure that the Corporation has the ability to generate sufficient cash or cash equivalents in a timely and cost effective manner to satisfy the cash flow requirements of depositors and borrowers and to meet its other commitments as they become due. The Corporation’s liquidity risk management process is designed to identify, measure, and manage the Corporation’s funding and liquidity risk to meet its daily funding needs in the ordinary course of business, as well as to address expected and unexpected changes in its funding requirements. The Corporation engages in various activities to manage its liquidity risk, including diversifying its funding sources, stress testing, and holding readily-marketable assets which can be used as a source of liquidity, if needed.

The Corporation performs dynamic scenario analysis in accordance with industry best practices. Measures have been established to ensure the Corporation has sufficient high quality short-term liquidity to meet cash flow requirements under stressed scenarios. In addition, the Corporation also reviews static measures such as deposit funding as a percentage of total assets and liquid asset levels. Strong capital ratios, credit quality, and core earnings are also essential to maintaining cost effective access to wholesale funding markets. At September 30, 2021, the Corporation was in compliance with its internal liquidity objectives and had sufficient asset-based liquidity to meet its obligations under a stressed scenario.

The Corporation maintains diverse and readily available liquidity sources, including:

•Investment securities, which are an important tool to the Corporation’s liquidity objective and can be pledged or sold to enhance liquidity, if necessary. See Note 6 Investment Securities of the notes to consolidated financial statements for additional information on the Corporation's investment securities portfolio, including pledged investment securities.

•Pledgeable loan collateral, which is eligible collateral with both the Federal Reserve Bank and the FHLB under established lines of credit. Based on the amount of collateral pledged, the FHLB established a collateral value from which the Bank may draw advances, and issue letters of credit in favor of public fund depositors, against the collateral. As of September 30, 2021, the Bank had $5.1 billion available for future funding. The Federal Reserve Bank also establishes a

68

collateral value of assets to support borrowings from the discount window. As of September 30, 2021, the Bank had $731 million available for discount window borrowings.

•A $200 million Parent Company commercial paper program, of which $55 million was outstanding as of September 30, 2021.

•Dividends and service fees from subsidiaries, as well as the proceeds from issuance of capital are also funding sources for the Parent Company.

•Acquisition related equity issuances by the Parent Company; the Corporation has filed a shelf registration statement with the SEC under which the Parent Company may, from time to time, offer shares of the Corporation’s common stock in connection with acquisitions of businesses, assets, or securities of other companies.

•Other issuances by the Parent Company; the Corporation maintains on file with the SEC a universal shelf registration statement, under which the Parent Company may offer the following securities, either separately or in units: debt securities, preferred stock, depositary shares, common stock, and warrants.

•Bank issuances; the Bank may also issue institutional CDs, network transaction deposits, and brokered CDs.

•Global Bank Note Program issuances; the Bank has implemented a program pursuant to which it may from time to time offer up to $2.0 billion aggregate principal amount of its unsecured senior and subordinated notes.

Credit ratings relate to the Corporation’s ability to issue debt securities and the cost to borrow money, and should not be viewed as an indication of future stock performance or a recommendation to buy, sell, or hold securities. Adverse changes in these factors could result in a negative change in credit ratings and impact not only the ability to raise funds in the capital markets but also the cost of these funds. The credit ratings of the Parent Company and the Bank at September 30, 2021 are displayed below:

For the nine months ended September 30, 2021, net cash provided by operating activities and financing activities was $364 million and $768 million, respectively, while net cash used in investing activities was $162 million for a net increase in cash and cash equivalents of $970 million since year-end 2020. At September 30, 2021, assets of $34.4 billion increased $1.0 billion, or 3%, from year-end 2020, primarily driven by a $983 million increase in interest-bearing deposits in other financial institutions and an increase of $808 million, or 26%, in investment securities AFS, at fair value, partially offset by a $830 million, or 3%, decrease in loans. On the funding side, deposits of $27.9 billion increased $1.4 billion, or 5%, from year-end related to deposit inflows from government stimulus programs and changing customer savings habits.

For the nine months ended September 30, 2020, net cash provided by operating and financing activities was $423 million and $1.7 billion, respectively, while net cash used in investing activities was $1.6 billion, for a net increase in cash and cash equivalents of $525 million from year-end 2019. At September 30, 2020, assets of $34.7 billion increased $2.3 billion, or 7%, from year-end 2019, primarily due to a $2.2 billion, or 10%, increase in loans, driven by the Corporation adding $1.0 billion in PPP loans and customers drawing on their lines to enhance their liquidity in response to the uncertainty surrounding the COVID-19 pandemic. Additionally, on February 14, 2020, the Corporation added $370 million in loans from the First Staunton acquisition. On the funding side, deposits of $26.7 billion increased $2.9 billion, or 12%, from year-end 2019 as advances on customer's loans were deposited into their deposit accounts, increasing their liquidity. Additionally, on February 14, 2020, the Corporation assumed $439 million of deposits from the First Staunton acquisition.

Quantitative and Qualitative Disclosures about Market Risk

Market risk and interest rate risk are managed centrally. Market risk is the potential for loss arising from adverse changes in the fair value of fixed income securities, equity securities, other earning assets and derivative financial instruments as a result of changes in interest rates or other factors. Interest rate risk is the potential for reduced net interest income resulting from adverse changes in the level of interest rates. As a financial institution that engages in transactions involving an array of financial products, the Corporation is exposed to both market risk and interest rate risk. In addition to market risk, interest rate risk is measured and managed through a number of methods. The Corporation uses financial modeling simulation techniques that measure the sensitivity of future earnings due to changing rate environments to measure interest rate risk.

Policies established by the Corporation’s ALCO and approved by the Board of Directors are intended to limit these risks. The Board has delegated day-to-day responsibility for managing market and interest rate risk to ALCO. The primary objectives of market risk management are to minimize any adverse effect that changes in market risk factors may have on net interest income and to offset the risk of price changes for certain assets recorded at fair value.

Interest Rate Risk

The primary goal of interest rate risk management is to control exposure to interest rate risk within policy limits approved by the Board of Directors. These limits and guidelines reflect the Corporation's risk appetite for interest rate risk over both short-term and long-term horizons. No interest rate limit breaches occurred during the first nine months of 2021.

The major sources of the Corporation's non-trading interest rate risk are timing differences in the maturity and re-pricing characteristics of assets and liabilities, changes in the shape of the yield curve, and the potential exercise of explicit or embedded options. We measure these risks and their impact by identifying and quantifying exposures through the use of sophisticated simulation and valuation models which are employed by management to understand NII at risk, interest rate sensitive EAR, and MVE at risk. The Corporation’s interest rate risk profile is such that a higher or steeper yield curve adds to income while a flatter yield curve is relatively neutral, and a lower or inverted yield curve generally has a negative impact on earnings. The Corporation's EAR profile is asset sensitive at September 30, 2021.

For further discussion of the Corporation's interest rate risk and corresponding key assumptions, see the Interest Rate Risk section of Management’s Discussion and Analysis of Financial Condition and Results of Operations included in the Corporation’s 2020 Annual Report on Form 10-K.

The sensitivity analysis included below is measured as a percentage change in NII and EAR due to gradual moves in benchmark interest rates from a baseline scenario over 12 months. We evaluate the sensitivity using: 1) a dynamic forecast incorporating expected growth in the balance sheet, and 2) a static forecast where the current balance sheet is held constant.

While a gradual shift in interest rates was used in this analysis to provide an estimate of exposure under a probable scenario, an instantaneous shift in interest rates would have a much more significant impact.

Table 16 Estimated % Change in Rate Sensitive Earnings at Risk Over 12 Months

	Sep 30, 2021				Dec 31, 2020
	Dynamic Forecast		Static Forecast		Dynamic Forecast		Static Forecast
Gradual Rate Change
100 bp increase in interest rates	5.8	%	5.5	%	6.2	%	6.3	%
200 bp increase in interest rates	12.1	%	11.0	%	12.8	%	12.7	%

At September 30, 2021, the MVE profile indicates a decrease in net balance sheet value due to instantaneous upward changes in rates.

Table 17 Market Value of Equity Sensitivity

	Sep 30, 2021		Dec 31, 2020
Instantaneous Rate Change
100 bp increase in interest rates	(1.2)	%	1.9	%
200 bp increase in interest rates	(2.6)	%	2.8	%

Since MVE measures the discounted present value of cash flows over the estimated lives of instruments, the change in MVE does not directly correlate to the degree that earnings would be impacted over a shorter time horizon (i.e., the current year). Further, MVE does not take into account factors such as future balance sheet growth, changes in product mix, changes in yield curve relationships, and changes in product spreads that could mitigate the adverse impact of changes in interest rates.

70

The above NII, EAR, and MVE measures do not include all actions that management may undertake to manage this risk in response to anticipated changes in interest rates.

(a) The ratio tangible common equity to tangible assets excludes goodwill and other intangible assets, net. This financial measure has been included as it is considered to be a critical     metric with which to analyze and evaluate financial condition and capital strength.

(b) These capital measurements are used by management, regulators, investors, and analysts to assess, monitor and compare the quality and composition of our capital with the capital of other financial services companies.

(c) The efficiency ratio as defined by the Federal Reserve guidance is noninterest expense (which includes the provision for unfunded commitments) divided by the sum of net interest income plus noninterest income, excluding investment securities gains / losses, net. The fully tax-equivalent efficiency ratio is noninterest expense (which includes the provision for unfunded commitments), excluding other intangible amortization, divided by the sum of fully tax-equivalent net interest income plus noninterest income, excluding investment securities gains / losses, net. The adjusted efficiency ratio is noninterest expense, which excludes the provision for unfunded commitments, other intangible amortization, acquisition related costs, and announced initiatives, divided by the sum of fully tax-equivalent net interest income plus noninterest income, excluding investment securities gains (losses), net, asset gains (losses), net, and gain on sale of branches, net. Management believes the adjusted efficiency ratio is a meaningful measure as it enhances the comparability of net interest income arising from taxable and tax-exempt sources and provides a better measure as to how the Corporation is managing its income and expenses by adjusting for acquisition related costs, provision for unfunded commitments, asset gains (losses), net, branch sales, and announced initiatives.

Sequential Quarter Results

The Corporation reported net income of $89 million for the third quarter of 2021, compared to net income of $91 million for the second quarter of 2021. Net income available to common equity was $85 million for the third quarter of 2021, or $0.56 for both basic and diluted earnings per common share. Comparatively, net income available to common equity for the second quarter of 2021 was $86 million, or $0.56 for both basic and diluted earnings per common share (see Table 1).

Fully tax-equivalent net interest income for the third quarter of 2021 was $188 million, $4 million, or 2%, higher than the second quarter of 2021. The net interest margin in the third quarter of 2021 was up 1 bp to 2.38%. Average earning assets increased $348 million, or 1%, to $31.4 billion in the third quarter of 2021, with investments and other increasing $562 million, or 8%. Average loans decreased $215 million, or 1%. On the funding side, total interest-bearing deposits increased $532 million, or 3%, primarily driven by customers holding proceeds from government stimulus programs in their deposit accounts and changing savings habits in response to the pandemic.(see Table 2).

The provision for credit losses had a release of $24 million for the third quarter of 2021, compared to a release of $35 million for the second quarter of 2021 (see Table 12). See discussion under sections: Provision for Credit Losses, Nonperforming Assets, and Allowance for Credit Losses on Loans.

Noninterest income for the third quarter of 2021 was $82 million, up $9 million, or 12%, from the second quarter of 2021, primarily due to gains on private equity investments of $5 million along with an increase of $3 million in mortgage banking, net, driven by a $2 million recovery of MSRs impairment during the third quarter of 2021 (see Table 3).

Noninterest expense for the third quarter of 2021 was $178 million, up $3 million, or 2%, from the second quarter of 2021 (see Table 4).

For the third quarter of 2021, the Corporation recognized income tax expense of $23 million, compared to income tax expense of $22 million for the second quarter of 2021. See Income Taxes section for a detailed discussion on income taxes.

Comparable Quarter Results

The Corporation reported net income of $89 million for the third quarter of 2021, compared to $45 million for the third quarter of 2020. Net income available to common equity was $85 million for the third quarter of 2021, or $0.56 for both basic and diluted earnings per common share. Comparatively, net income available to common equity for the third quarter of 2020 was $40 million, or $0.26 for both basic and diluted earnings per share (see Table 1).

Fully tax-equivalent net interest income for the third quarter of 2021 was $188 million, $2 million, or 1%, higher than the third quarter of 2020. The net interest margin between the comparable quarters was up 7 bp, to 2.38% in the third quarter of 2021. The increase in net interest income and net interest margin was due to lower interest bearing liability costs as excess liquidity was deployed to control those costs. Average earning assets decreased $726 million, or 2%, to $31.4 billion in the third quarter of 2021 as average loans decreased $1.1 billion, or 4%, partially offset by an increase of $353 million, or 5%, in investments and other, driven by higher interest-bearing deposits in other financial institutions. On the funding side, average interest-bearing deposits increased $505 million, or 3%, from the third quarter of 2020, due to increases in lower cost deposits, partially offset by a decrease in higher cost deposits. Average noninterest-bearing deposits increased $730 million, or 10%, to $8.1 billion. Average short and long-term funding decreased $2.0 billion, or 48%, driven by decreases in PPPLF, which was paid in full in the fourth quarter of 2020, and the Corporation's prepayment of $950 million in long-term FHLB advances during the third quarter of 2020 (see Table 2).

The provision for credit losses had a release of $24 million for the third quarter of 2021, compared to $43 million of provision expense for the third quarter of 2020, as a result of improving credit quality within the loan portfolio and an improving economic forecast (see Table 12). See discussion under sections: Provision for Credit Losses, Nonperforming Assets, and Allowance for Credit Losses on Loans.

Noninterest income for the third quarter of 2021 was $82 million, up $7 million, or 9%, compared to the third quarter of 2020, primarily due to gains on private equity investments of $5 million during the third quarter of 2021 (see Table 3).

Noninterest expense decreased $50 million, or 22%, to $178 million for the third quarter of 2021, primarily due to the prepayment of $950 million of long-term FHLB advances during the third quarter of 2020 that incurred a loss of $45 million on the prepayment. (see Table 4).

The Corporation recognized income tax expense of $23 million for the third quarter of 2021, compared to an income tax benefit of $58 million for the third quarter of 2020. The increase in income tax expense was primarily due to tax planning strategies which occurred during the third quarter of 2020. See section Income Taxes for a detailed discussion on income taxes.

Notable Changes in Segment Financial Data

The Corporate and Commercial Specialty segment consists of lending and deposit solutions to larger businesses, developers, not-for-profits, municipalities, and financial institutions, and 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.

•Revenue increased $11 million from the nine months ended September 30, 2020 and increased $7 million from the three months ended September 30, 2020, driven by higher asset gains.

•Provision for credit losses increased $7 million from the nine months ended September 30, 2020 as a result of the long term annual net charge off rates attributable to the current portfolio.

•Noninterest expense increased $12 million from the nine months ended September 30, 2020 driven by an increase in personnel expense due to an increase in funding of the management incentive plan partially offset by lower salary expense as a result of fewer employees.

•Average loans increased $456 million from the nine months ended September 30, 2020, primarily driven by a $412 million increase in CRE loans.

The Community, Consumer, and Business segment consists of lending, deposit solutions, and historically offered ancillary financial services, primarily insurance and risk consulting, to individuals and small to mid-sized businesses.

•Revenue decreased $42 million from the nine months ended September 30, 2020, primarily driven by the sale of ABRC during the second quarter of 2020, which lowered insurance commissions and fees by $45 million. Revenue increased $4 million from the three months ended September 30, 2020, primarily driven by an increase in service charges and deposit account fees. These fees were waived during 2020 in response to the COVID-19 pandemic.

•Noninterest expense decreased $45 million from the nine months ended September 30, 2020, and decreased $7 million from the three months ended September 30, 2020, primarily driven by a decrease in personnel expense, which was largely due to a reduction in FTEs as a result of branch consolidations and the sale of ABRC, along with lower loan and foreclosure costs.

•Average loans decreased $611 million from the nine months ended September 30, 2020, primarily driven by a decrease in residential mortgages as a result of higher refinances, as well as decreases in home equity and other consumer portfolios. Average loans decreased $772 million from the three months ended September 30, 2020 driven by decreases across all loan categories.

•Average deposits increased $1.9 billion from the nine months ended September 30, 2020, and increased $1.5 billion from the three months ended September 30, 2020. The increase was primarily driven by customers holding proceeds from government stimulus programs, and more recently driven by changes in consumer saving habits.

The Risk Management and Shared Services segment includes key shared Corporate functions, Parent Company activity, intersegment eliminations, and residual revenues and expenses.

•Revenues decreased $183 million from the nine months ended September 30, 2020, primarily driven by the $163 million asset gain on sale of ABRC which occurred during the second quarter of 2020.

•Provision for credit losses decreased $244 million from the nine months ended September 30, 2020, and decreased $65 million from the three months ended September 30, 2020, as a result of improving credit quality within the loan portfolio and an improving economic forecast.

•Noninterest expense decreased $42 million from the nine months ended September 30, 2020 and decreased $48 million from the three months ended September 30, 2020, primarily driven by a loss on the prepayment of FHLB advances incurred during the third quarter of 2020.

•Average loans decreased $188 million from the nine months ended September 30, 2020 and decreased $203 million from the three months ended September 30, 2020 primarily driven by a decrease in commercial and business lending.

76

•Average deposits decreased $571 million from the nine months ended September 30, 2020, and decreased $640 million from the three months ended September 30, 2020. These decreases were primarily driven by a decrease in network deposits for both time periods.

Critical Accounting Policies

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, goodwill impairment assessment, MSRs valuation, and income taxes. A discussion of these policies can be found in the Critical Accounting Policies section in Management's Discussion and Analysis of Financial Condition and Results of Operations included in the Corporation’s 2020 Annual Report on Form 10-K. There have been no changes in the Corporation's application of critical accounting policies since December 31, 2020.

Recent Developments

On October 26, 2021, the Corporation’s Board of Directors declared a regular quarterly cash dividend of $0.20 per common share, payable on December 15, 2021 to shareholders of record at the close of business on December 1, 2021. The Board of Directors also declared a regular quarterly cash dividend of $0.3671875 per depositary share on Associated's 5.875% Series E Perpetual Preferred Stock, payable on December 15, 2021 to shareholders of record at the close of business on December 1, 2021. The Board of Directors also declared a regular quarterly cash dividend of $0.3515625 per depositary share on Associated's 5.625% Series F Perpetual Preferred Stock, payable on December 15, 2021 to shareholders of record at the close of business on December 1, 2021.

In addition, the Board of Directors authorized the repurchase of up to $100 million of Associated's common stock. This repurchase authorization is in addition to the authority remaining under the previous program. See Part II, Item 2, Unregistered Sales of Equity Securities and Use of Proceeds, for more information on the Corporation's share repurchase program.

ITEM 3.     Quantitative and Qualitative Disclosures About Market Risk

Information required by this item is set forth in Item 2 under the captions Quantitative and Qualitative Disclosures about Market Risk and Interest Rate Risk.

77

ITEM 4.     Controls and Procedures

The Corporation maintains disclosure controls and procedures as required under Rule 13a-15 promulgated under the Securities Exchange Act of 1934, as amended, that are designed to ensure that information required to be disclosed in the Corporation's Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the Corporation’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

As of September 30, 2021, the Corporation’s management carried out an evaluation, under the supervision and with the participation of the Corporation’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of its disclosure controls and procedures. Based on the foregoing, its Chief Executive Officer and Chief Financial Officer concluded that the Corporation’s disclosure controls and procedures were effective as of September 30, 2021.

No changes were made to the Corporation’s internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act of 1934) during the last fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Corporation’s internal control over financial reporting.

ITEM 1. Legal Proceedings

The information required by this item is set forth in Part I, Item 1 under Note 12 Commitments, Off-Balance Sheet Arrangements, Legal Proceedings and Regulatory Matters of the notes to consolidated financial statements.

ITEM 1A. Risk Factors

The following risk factors supplement the Risk Factors described in the Corporation’s 2020 Annual Report on Form 10-K and should be read in conjunction therewith

Changes in the federal, state, or local tax laws may negatively impact our financial performance. On March 31, 2021, President Biden unveiled his infrastructure plan, which includes a proposal to increase the federal corporate tax rate from 21% to 28% as part of a package of tax reforms to help fund the spending proposals in the plan. If adopted as proposed, the increase of the corporate tax rate would adversely affect our results of operations in future periods. Congress is expected to debate the adoption of an infrastructure initiative in the coming weeks and months; however, the prospects and timing for the enactment of any such legislation, as well as its specific provisions, including funding options, and the extent of its potential impact on our results of operations if enacted, cannot be predicted at this time.

Cyberattacks, including those targeting critical infrastructure sectors, have become more frequent and sophisticated. Critical infrastructure sectors, including financial services, increasingly have been the targets of cyberattacks, including attacks emanating from foreign countries such as the attack on the information technology company SolarWinds, which affected many Fortune 500 companies as well as U.S. government agencies. Attacks involving large financial institutions, including denial of service attacks designed to disrupt external customer-facing services, nation state cyberattacks and ransomware attacks designed to deny organizations access to key internal resources or systems, and targeted social engineering and email attacks designed to allow unauthorized persons to obtain access to an institution’s information systems and data or that of its customers are becoming more common and increasingly sophisticated and can be difficult to prevent. Reports of ransomware incidents specifically have increased by approximately 300% since the start of 2020 and information technology software supply chain attacks, including those involving financial institutions, also have increased during this period, some of which have resulted in temporary, but impactful, disruptions to the functioning of critical infrastructure sectors or the operations of specific institutions. In addition, cybersecurity risks for financial institutions have evolved as a result of the use of new technologies, devices and delivery channels to transmit data and conduct financial transactions, while the ongoing and widespread remote work environment necessitated by the COVID-19 pandemic has subjected institutions to additional cybersecurity vulnerabilities and risks.

Any successful cyberattack or other security breach involving the misappropriation, loss or other unauthorized disclosure of confidential customer information or that compromises our ability to function could severely damage our reputation, erode confidence in the security of our systems, products and services, expose us to the risk of litigation and liability, disrupt our operations and have a material adverse effect on our business. Any successful cyberattack may also subject the Corporation to regulatory investigations, litigation or enforcement, or require the payment of regulatory fines or penalties or undertaking of costly remediation efforts with respect to third parties affected by a cybersecurity incident, all or any of which could adversely affect the Corporation’s business, financial condition or results of operations and damage its reputation.

Recent actions by the Biden Administration regarding competition in the financial services and technology sectors may adversely impact our business. On July 9, 2021, President Biden issued an Executive Order on Promoting Competition in the American Economy (the “Executive Order”). Among other initiatives, the Executive Order (i) encourages the federal banking agencies to review their current merger oversight practices under the Bank Holding Company Act of 1956, as amended, and the Bank Merger Act and, within 180 days of the date of the Executive Order, adopt a plan for revitalization of such practices; and (ii) directs the Bureau of Consumer Financial Protection (the “CFPB”) to commence or continue a rulemaking to facilitate the portability of consumer financial transaction data for the purpose of providing consumers with greater flexibility in switching financial institutions and using innovative financial products.

Although the scope and substance of any action by the federal banking agencies in response to the directives set forth in the Executive Order cannot be predicted at this time, the potential for increased regulatory scrutiny of bank mergers and acquisitions may adversely affect the marketplace for such transactions in the near- to medium-term and could result in our acquisitions in future periods being delayed, impeded or restricted in certain respects due to enhanced regulatory review processes. Similarly, although the CFPB has published principles for consumer-authorized financial data sharing and aggregation, we cannot predict the scope, substance or timing of any future CFPB rulemaking regarding the portability of financial transaction data in response to the Executive Order. The impact of any such rulemaking on the conduct of our customers also cannot be predicted. However, the adoption of any such rule could result in increased volatility of consumer accounts and expose the Corporation to additional operational, strategic, regulatory and compliance risks.

79

We are subject to environmental, social and governance risks that could adversely affect our reputation and the market price of our securities. The Corporation is subject to a variety of risks arising from environmental, social and governance matters or “ESG” matters. ESG matters include climate risk, hiring practices, the diversity of our work force, and racial and social justice issues involving our personnel, customers and third parties with whom we otherwise do business. Risks arising from ESG matters may adversely affect, among other things, our reputation and the market price of our securities.

In recognition of the risks posed by climate change, the Corporation has taken a variety of actions to manage its carbon footprint and has sought to engage in sustainable lending and investment activities, specifically including supporting renewable energy projects. However, we cannot guarantee the success of these actions, nor can we make any assurances that our regulators, investors in our securities or other third parties, such as environmental advocacy organizations, will find our efforts to support climate-related initiatives to be sufficient. Further, we may be exposed to negative publicity based on the identity and activities of those to whom we lend and with which we otherwise do business and the public’s view of the approach and performance of our customers and business partners with respect to ESG matters. Any such negative publicity could arise from adverse news coverage in traditional media and could also spread through the use of social media platforms. The Corporation’s relationships and reputation with its existing and prospective customers and third parties with which we do business could be damaged if we were to become the subject of any such negative publicity. This, in turn, could have an adverse effect on our ability to attract and retain customers and employees and could have a negative impact on the market price for securities.

Investors have begun to consider the steps taken and resources allocated by financial institutions and other commercial organizations to address ESG matters when making investment and operational decisions. Certain investors are beginning to incorporate the business risks of climate change and the adequacy of companies’ responses to the risks posed by climate change and other ESG matters into their investment theses. These shifts in investing priorities may result in adverse effects on the market price of our securities to the extent that investors determine that the Corporation has not made sufficient progress on ESG matters.

The leadership of each of the Office of the Comptroller of the Currency (the "OCC"), the Federal Reserve Board and the U.S. Treasury Department have indicated increased expectations of larger financial institutions to measure, monitor and manage climate related risk as part of their enterprise risk management processes. For instance, the OCC currently is engaged in multiple collaborative initiatives with other governmental authorities to assess the physical and transition risk posed by climate change and the appropriate corresponding expectations for bank risk management. The OCC also has appointed its first ever Climate Change Risk Officer to assist with these initiatives and to support the agency's efforts to enhance its supervision of climate change risk management. Further, the Federal Reserve Board has signaled that it is in the process of developing scenario analysis to model the possible financial risks associated with climate change. When developed, the resilience of large banking organizations, as well as the broader financial system, will be evaluated against these climate change-related scenarios as part of the stress testing process. Although these requirements would not apply to a banking organization of our size, as the Corporation continues to grow and expand the scope of our operations, our regulators generally will expect us to enhance our internal control programs and processes, including with respect to stress testing under a variety of adverse scenarios and related capital planning. To the extent that these initiatives lead to the promulgation of new regulations or supervisory guidance applicable to the Corporation, we would expect to experience increased compliance costs and other compliance-related risks.

Fiscal challenges facing the U.S. government could negatively impact financial markets which, in turn, could have an adverse effect on our financial position or results of operations. Recent federal budget deficit concerns and political conflict over legislation to raise the U.S. government's debt limit have increased the possibility of a default by the U.S. government on its debt obligations, related credit-rating downgrades, or an economic recession in the United States. Many of our investment securities are issued by the U.S. government and government agencies and sponsored entities. As a result of uncertain domestic political conditions, including the possibility of the federal government defaulting on its obligations for a period of time due to debt ceiling limitations or other unresolved political issues, investments in financial instruments issued or guaranteed by the federal government pose liquidity risks. In connection with prior political disputes over U.S. fiscal and budgetary issues leading to the U.S. government shutdown in 2011, S&P lowered its long-term sovereign credit rating on the U.S. from AAA to AA+. A further downgrade, or a similar downgrade by other rating agencies, in response to current political dynamics, as well as sovereign debt issues facing the governments of other countries, could have a material adverse impact on financial markets and economic conditions in the U.S. and worldwide.

ITEM 2. Unregistered Sales of Equity Securities and Use of Proceeds

During the third quarter of 2021, the Corporation repurchased $60 million of common stock, including $60 million of open market purchases and approximately $112,000 of repurchases related to tax withholding on equity compensation, or approximately 2.9 million shares, of common stock. The repurchase details are presented in the table below:

Common Stock Purchases

	Total Number  of Shares Purchased(a)	Average Price Paid per Share		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs	Maximum Number of Shares that May Yet Be Purchased Under the Plans or Programs(b)
Period
July 1, 2021 - July 31, 2021	468,431	$	19.77	468,431	—
August 1, 2021 - August 31, 2021	2,455,088	20.70		2,450,585	—

Total	2,924,539	$	20.55	2,919,016	217,463

(a) During the third quarter of 2021, the Corporation repurchased 5,523 common shares for minimum tax withholding settlements on equity compensation. These purchases do not
    count against the maximum number of shares that may yet be purchased under the Board of Directors’ authorization described below.
(b) At September 30, 2021, there remained approximately $5 million authorized to be repurchased in the aggregate. Approximately 217,000 shares of common stock remained
available to be repurchased under this Board authorization based on the closing share price on September 30, 2021.

Repurchases under Board authorized repurchase programs are subject to any necessary regulatory approvals and other limitations and may occur from time to time in open market purchases, block transactions, private transactions, accelerated share repurchases, or similar facilities.

Preferred Stock Purchases

During the third quarter of 2021, the Corporation redeemed all outstanding depositary shares of the Corporation's Series D Preferred Stock, but did not repurchase any other shares of preferred stock.

The repurchase of depositary shares is 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.

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, goodwill impairment assessment, MSRs valuation, and income taxes. 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.

Acquisitions and Dispositions

Acquisitions:

The Corporation has not had any acquisitions during the first nine months of 2021.

2020

First Staunton Acquisition

On February 14, 2020, the Corporation completed its acquisition of First Staunton. The purchase price was based on an assumed 4% deposit premium at announcement. The conversion of the branches was completed simultaneously with the close of the transaction, expanding the Bank's presence into nine new Metro-East St. Louis communities. As a result of the acquisition and other consolidations, a net of seven branch locations were added.

The Corporation recorded $15 million in goodwill related to the First Staunton acquisition. Goodwill created by the acquisition is not tax deductible.

The following table presents the estimated fair values of the assets acquired and liabilities assumed as of the acquisition date related to the First Staunton acquisition:

For a description of methods used to determine the fair value of significant assets and liabilities presented on the balance sheet above, see Assumptions section of this Note.

The Corporation has purchased loans with the First Staunton acquisition, for which there was, at acquisition, evidence of more than insignificant deterioration of credit quality since origination (PCD). The carrying amount of those loans is as follows:

($ in Thousands)	February 14, 2020
Purchase price of loans at acquisition	$	77,221
Allowance for credit losses at acquisition	3,504
Non-credit discount/(premium) at acquisition	(951)
Par value of acquired loans at acquisition	$	79,774

The Corporation acquired no PCD securities in connection with the acquisition.

Assumptions

Investment Securities: The fair value of investments on the date of acquisition was determined utilizing an external third party broker opinion of the market value.

Loans: Fair values for loans were based on a discounted cash flow methodology that considered factors including the type of loan and related collateral, classification status, fixed or variable interest rate, term of loan, amortization status and current discount rates. For the non-credit (interest and liquidity) premium, loans were grouped together according to similar characteristics when applying various valuation techniques. For the credit discount, loans were also grouped based on whether they had more than insignificant deterioration in credit since origination.

CDIs: This intangible asset represents the value of the relationships with deposit customers. The fair value was estimated based on a discounted cash flow methodology that gave appropriate consideration to expected customer attrition rates, net maintenance cost of the deposit base, alternative cost of funds, and the interest costs associated with customer deposits. The CDIs are being amortized on a straight-line basis over 10 years.

Time Deposits: The fair value for time deposits are estimated using a discounted cash flow calculation that applies interest rates currently being offered to the contractual interest rates on such time deposits.

FHLB Borrowings: The fair value of FHLB advances is estimated based on quoted market prices for the instrument if available, or for similar instruments if not available, or by using discounted cash flow analyses, based on current incremental borrowing rates for similar types of instruments.

Dispositions:

2021

On March 1, 2021, the Corporation closed on the sale of its wealth management subsidiary, Whitnell, to Rockefeller for a purchase price of $8 million. Associated reported a first quarter 2021 pre-tax gain of $2 million, included in asset gains (losses), net on the consolidated statements of income, in conjunction with the sale.

On February 26, 2021, the Bank completed the sale of one branch located in Monroe, Wisconsin to Summit Credit Union. Under the terms of the transaction, Associated Bank sold $31 million in total deposits and no loans. Associated Bank received an approximately 4% purchase premium on deposits transferred.

2020

On June 30, 2020, the Corporation completed the sale of ABRC to USI for $266 million in cash. Associated recorded a second quarter 2020 pre-tax book gain of $163 million in conjunction with the sale.

On December 11, 2020, the Bank completed the sale of five branches in Peoria, Illinois to Morton Community Bank. Under the terms of the transaction, the Bank sold $180 million in total deposits and no loans. Associated Bank received a 4% purchase premium on deposits transferred. With the sale of these branches, the Bank exited the Peoria market.

On December 11, 2020, the Bank completed the sale of two branches in southwest Wisconsin to Royal Bank. Under the terms of the transaction, Associated Bank sold $53 million in total deposits and no loans. Associated Bank received a 4% purchase premium on deposits transferred in the Prairie du Chien and Richland Center branches.

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:

Stock-Based Compensation

9 Months Ended

Sep. 30, 2021

Retirement Benefits [Abstract]

Stock-Based Compensation

Stock-Based Compensation

The fair values of stock options and restricted stock awards (including restricted stock units) 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.

Assumptions are used in estimating the fair value of stock options granted. The weighted average expected life of the stock option represents the period of time stock options are expected to be outstanding and is estimated using historical data of stock option exercises and forfeitures. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. The expected volatility is based on the implied volatility of the Corporation’s stock.

The Corporation did not grant stock options in the first nine months of 2021. The following assumptions were used in estimating the fair value for options granted for the full year 2020:

	2020
Dividend yield	3.50	%
Risk-free interest rate	1.60	%
Weighted average expected volatility	21.00	%
Weighted average expected life	5.75 years
Weighted average per share fair value of options	$2.39

A summary of the Corporation’s stock option activity for the nine months ended September 30, 2021 is presented below:

Stock Options	Shares(a)	Weighted Average Exercise Price		Weighted Average Remaining Contractual Term	Aggregate Intrinsic Value(a)
Outstanding at December 31, 2020	6,473	$	19.77	6.23 years	$	2,005
Exercised	1,116	16.36
Forfeited or expired	97	22.61
Outstanding at September 30, 2021	5,260	$	20.44	6.01 years	$	11,044
Options Exercisable at September 30, 2021	3,694	$	20.58	5.19 years	$	8,062

(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 nine months ended September 30, 2021, the intrinsic value of stock options exercised was $6 million compared to less than $1 million for the nine months ended September 30, 2020. For the nine months ended September 30, 2021, the total fair value of stock options vested was $3 million compared to $4 million for the nine months ended September 30, 2020.

The Corporation recognized compensation expense for the vesting of stock options of $1 million for the nine months ended September 30, 2021, compared to $3 million for the nine months ended September 30, 2020. Included in compensation expense for 2021 was approximately $65,000 for the accelerated vesting of stock options granted to retirement eligible colleagues. At September 30, 2021, the Corporation had $2 million 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 of earnings per share and total shareholder return 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 nine months ended September 30, 2021:

Restricted Stock Awards	Shares(a)	Weighted Average Grant Date Fair Value
Outstanding at December 31, 2020	2,293	$	20.70
Granted	1,212	20.00
Vested	797	21.23
Forfeited	52	22.39
Outstanding at September 30, 2021	2,656	$	19.86

(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. Performance-based restricted stock awards granted during 2020 and 2021 will cliff-vest after the three year performance period has ended. Service-based restricted stock awards granted during 2020 and 2021 will vest ratably over a period of four years. Expense for restricted stock awards issued of $11 million was recorded for the nine months ended September 30, 2021 and $15 million was recorded for the nine months ended September 30, 2020. Included in compensation expense for the first nine months of 2021 was $2 million of expense for the accelerated vesting of restricted stock awards granted to retirement eligible colleagues. The Corporation had $24 million of unrecognized compensation costs related to restricted stock awards at September 30, 2021 that are expected to be recognized over the remaining requisite service periods that extend predominately through the first quarter of 2025.

The Corporation has the ability to issue shares from treasury or new shares upon the exercise of stock options or the granting of restricted stock awards. 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 second quarter of 2021, the Corporation sold $107 million of lower yielding FFELP student loan asset backed securities at a slight gain and reinvested the proceeds into higher yielding mortgage backed securities. During the first quarter of 2021, the Corporation sold $51 million of lower yielding U.S. Treasury and Agency securities at a slight loss to take advantage of the steeper yield curve by reinvesting the proceeds into similar but higher yielding, longer duration securities.

During the second quarter of 2020, the Corporation sold $261 million of less liquid securities at a gain of $3 million, reinvesting the proceeds into more liquid securities in order to further improve portfolio liquidity. During the first quarter of 2020, the Corporation sold $281 million of primarily prepayment sensitive mortgage-related securities at a gain of $6 million. Additionally, in February 2020, the Corporation sold $84 million of certain securities acquired in the First Staunton acquisition that did not fit the parameters of the Corporation's current investment strategy.

Investment securities with a carrying value of $2.2 billion and $1.6 billion at September 30, 2021 and December 31, 2020, respectively, were pledged to secure certain deposits or for other purposes as required or permitted by law.

Accrued interest receivable on HTM securities totaled $12 million and $14 million at September 30, 2021 and December 31, 2020, respectively. Accrued interest receivable on AFS securities totaled $9 million and $8 million at September 30, 2021 and December 31, 2020, 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 September 30, 2021 and 2020.

A security is considered past due once it is 30 days past due under the terms of the agreement. At both September 30, 2021 and December 31, 2020, the Corporation had no past due HTM securities.

The allowance for credit losses on HTM securities was approximately $49,000 at September 30, 2021 and approximately $67,000 at December 31, 2020, attributable entirely to the Corporation's municipal securities, included in investment securities HTM, 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.

The Corporation reviews the AFS investment securities portfolio on a quarterly basis to monitor its credit exposure. 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 September 30, 2021 represent credit deterioration as these unrealized losses are primarily attributable to changes in interest rates and the current market conditions. The U.S. Treasury 3 year and 5 year rates increased by 36 bp and 62 bp, respectively, from December 31, 2020. 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 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 $82 million at both September 30, 2021 and December 31, 2020. The Corporation had Federal Reserve Bank stock of $87 million at both September 30, 2021 and December 31, 2020. Accrued interest receivable on FHLB stock totaled approximately $974,000 and $972,000 at September 30, 2021 and December 31, 2020, respectively. There was $327,000 accrued interest receivable on Federal Reserve Bank stock at September 30, 2021 and none at December 31, 2020. 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 a money market mutual fund. At September 30, 2021 and December 31, 2020, the Corporation had equity securities with readily determinable fair values of $4 million and $2 million, respectively.

Equity securities without readily determinable fair values: The Corporation's portfolio of equity securities without readily determinable fair values primarily consists of 77,996 Visa Class B restricted shares, 77,000 of which the Corporation received in 2008 as part of Visa's initial public offering and carried at fair value after the Corporation donated 42,039 Visa Class B restricted shares to the Corporation's Charitable Remainder Trust during the second quarter of 2019, with the subsequent sale of those shares resulting in an observable market price after the shares were previously carried at a zero cost basis. During the first quarter of 2020, the Corporation acquired 996 Visa Class B restricted shares from the acquisition of First Staunton, and those shares are carried at a zero cost basis due to the lack of an observable market price since the time of acquisition. The Corporation had equity securities without readily determinable fair values of $14 million at September 30, 2021 and $13 million at December 31, 2020

(a) Revolving loans converted to term loans are also reported in their year of origination.

(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) Accruing TDRs are included in pass unless otherwise rated as special mention.

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 allowance for loan losses, allowance for unfunded commitments, 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. 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.

The Corporation had a recorded investment of $14 million in loans modified as TDRs during the nine months ended September 30, 2021, of which $7 million were in accrual status, included in pass or special mention based on their risk rating within the credit quality tables, and $7 million were in nonaccrual within the credit quality tables, pending a sustained period of repayment. Short-term loan modifications made in good faith to help ease the adverse effects of the COVID-19 pandemic are not categorized as TDRs in accordance with the CARES Act. The following table provides the number of loans modified in a TDR by loan portfolio, the recorded investment, and unpaid principal balance for the nine months ended September 30, 2021 and 2020:

	Nine months ended Sep 30, 2021					Nine months ended Sep 30, 2020

(a) Represents post-modification outstanding recorded investment.
(b) Represents pre-modification outstanding recorded investment.

Restructured loan modifications may include payment schedule modifications, interest rate concessions, maturity date extensions, modification of note structure (A/B Note), non-reaffirmed Chapter 7 bankruptcies, principal reduction, or some combination of these concessions. During the nine months ended September 30, 2021, restructured loan modifications of commercial loans primarily included maturity date extensions and payment schedule modifications. 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 nine months ended September 30, 2021.

The following table provides the number of loans modified in a TDR during the previous twelve months which subsequently defaulted during the nine months ended September 30, 2021 and 2020, and the recorded investment in these restructured loans as of September 30, 2021 and 2020:

	Nine months ended Sep 30, 2021			Nine months ended Sep 30, 2020
($ in Thousands)	Number of Loans	Recorded Investment		Number of Loans	Recorded Investment
Residential mortgage	2	$	200	5	$	1,036
Home equity	—	—		4	208
Total loans modified	2	$	200	9	$	1,244

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 September 30, 2021, the Corporation had $17 million in loans meeting this classification compared to $68 million at December 31, 2020. Of the loans classified as probable TDRs at September 30, 2021, the entire $17 million was related to the oil and gas portfolio.

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 September 2021, 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.

Loans Acquired in Acquisitions

Loans acquired in a business combination after January 1, 2020 are recorded in accordance with ASC Topic 326. See Note 2 for more information on loans acquired in a business combination. After January 1, 2020, acquired loans were segregated into two types:

•Non-PCD loans are accounted for in accordance with ASC Topic 310-20 "Nonrefundable Fees and Other Costs" as these loans do not show evidence of credit deterioration since origination. The allowance for loan losses on these loans is recorded through provision for credit losses on the consolidated statements of income at acquisition.

•PCD loans are loans demonstrating more than insignificant credit deterioration and are accounted for in accordance with ASC Topic 326-30. Under this guidance, the credit mark on acquired assets grosses up the ACLL and the amortized cost of the loan.

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 2021, 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 2021 impairment test that have changed the Corporation's impairment assessment conclusion. There were no impairment charges recorded in 2020 or the first nine months of 2021.

At both September 30, 2021 and December 31, 2020, the Corporation had goodwill of $1.1 billion. During the first quarter of 2021, there was a reduction of $4 million of goodwill related to the sale of Whitnell.

Other Intangible Assets

The Corporation has other intangible assets that are amortized, consisting of CDIs and MSRs. For CDIs and other intangibles, changes in the gross carrying amount, accumulated amortization, and net book value were as follows:

($ in Thousands)	Nine months ended Sep 30, 2021		Year Ended Dec 31, 2020

Mortgage Servicing Rights

The Corporation sells residential mortgage loans in the secondary market and typically retains the right to service the loans sold. MSRs are amortized in proportion to and over the period of estimated net servicing income and assessed for impairment at each reporting date.

The Corporation evaluates its MSRs asset for impairment at minimum on a quarterly basis. Impairment is 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 fall, prepayment speeds are usually faster and the value of the MSRs asset generally decreases, requiring additional valuation reserve. Conversely, as mortgage interest rates rise, prepayment speeds are usually slower and the value of the MSRs asset generally increases, requiring less valuation reserve. A valuation allowance is established, through a charge to earnings, to the extent the amortized cost of the MSRs exceeds the estimated fair value by stratification. An other-than-temporary impairment (i.e., recoverability is considered remote when considering interest rates and loan pay off activity) is recognized as a write-down of the MSRs asset and the related valuation allowance (to the extent a valuation allowance is available) and then against earnings. A direct write-down permanently reduces the carrying value of the MSRs asset and valuation allowance, precluding subsequent recoveries. 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 and the MSRs valuation allowance is as follows:

Securities Sold Under Agreements to Repurchase

The Corporation enters into agreements under which it sells securities subject to an obligation to repurchase the same or similar securities. 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. As of September 30, 2021, the Corporation pledged agency mortgage-related securities with a fair value of $364 million as collateral for the repurchase agreements. Securities pledged as collateral under repurchase agreements are maintained with the Corporation's safekeeping agents and are monitored on a daily basis due to the market risk of fair value changes in the underlying securities. The Corporation generally pledges excess securities to ensure there is sufficient collateral to satisfy short-term fluctuations in both the repurchase agreement balances and the fair value of the underlying securities.

The remaining contractual maturity of the securities sold under agreements to repurchase on the consolidated balance sheets as of September 30, 2021 and December 31, 2020 are presented in the following table:

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 $78 million and $72 million of investment securities as collateral at September 30, 2021, and December 31, 2020, respectively. At September 30, 2021, the Corporation posted $18 million of cash collateral compared to $31 million at December 31, 2020.

Federal regulations require the Corporation to clear all LIBOR 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 commodity prices. 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 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: Commodity contracts are entered into primarily for the benefit of commercial customers seeking to manage their exposure to fluctuating commodity prices. The Corporation mitigates 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 to sell residential mortgage loans 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.

The following table presents the total notional amounts and gross fair values of the Company’s derivatives, as well as the balance sheet netting adjustments as of September 30, 2021 and December 31, 2020. 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 September 30, 2021 and December 31, 2020. 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.

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, commodity contracts to manage commercial customers' exposure to fluctuating commodity prices, 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. 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, commodity, 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 on a net basis, net of cash collateral, 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, commodity, and foreign exchange assets and liabilities subject to an enforceable master netting arrangement. The interest, commodity and foreign exchange agreements the Corporation has with its commercial customers are not subject to an enforceable master netting arrangement and are therefore excluded from this table:

Commitments, Off-Balance Sheet Arrangements, Legal Proceedings and Regulatory Matters

Commitments, Off-Balance Sheet Arrangements, Legal Proceedings and Regulatory Matters The Corporation utilizes a variety of financial instruments in the normal course of business to meet the financial needs of its customers and to manage its own exposure to fluctuations in interest rates. These financial instruments include lending-related and other commitments (see below) as well as derivative instruments (see Note 10). The following is a summary of lending-related commitments:

($ in Thousands)	Sep 30, 2021		Dec 31, 2020

Commercial letters of credit(a)	6,309		3,642
Standby letters of credit(c)	264,123		278,798

(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 September 30, 2021 or December 31, 2020.
(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 for both September 30, 2021 and December 31, 2020, 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)	Nine months ended Sep 30, 2021		Year Ended Dec 31, 2020
Allowance for Unfunded Commitments
Balance at beginning of period	$	47,776	$	21,907
Cumulative effect of ASU 2016-13 adoption (CECL)	N/A		18,690
Balance at beginning of period, adjusted	47,776		40,597
Provision for unfunded commitments	(6,500)		7,000
Amount recorded at acquisition	N/A		179
Balance at end of period	$	41,276	$	47,776

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 to sell residential mortgage loans 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, federal and state 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 September 30, 2021 was $277 million, compared to $272 million at December 31, 2020, 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 $24 million and $18 million for the nine months ended September 30, 2021 and 2020, respectively, and $8 million and $6 million for the three months ended September 30, 2021 and 2020, respectively. The Corporation's remaining investment in qualified affordable housing projects accounted for under the proportional amortization method totaled $270 million at September 30, 2021 and $268 million at December 31, 2020.

The Corporation’s unfunded equity contributions relating to investments in federal and state qualified affordable housing and federal and state historic projects are recorded in accrued expenses and other liabilities on the consolidated balance sheets. The Corporation’s remaining unfunded equity contributions totaled $101 million and $118 million at September 30, 2021 and December 31, 2020, respectively.

For the nine months ended September 30, 2021 and the year ended December 31, 2020, 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 and public 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 $24 million and $25 million at September 30, 2021 and December 31, 2020, respectively, included in tax credit and other investments on the consolidated balance sheets.

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.

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 $6 million and $10 million for the nine months ended September 30, 2021 and the year ended December 31, 2020, respectively. There were approximately $114,000 of loss reimbursement and settlement claims paid for the nine months ended September 30, 2021 and there were no such claims for the year ended December 31, 2020. Make whole requests during 2020 and the first nine months of 2021 generally arose from loans sold during the period of January 1, 2012 to December 31, 2020. Since January 1, 2012, loans sold totaled $15.7 billion at the time of sale, and consisted primarily of loans sold to GSEs. As of September 30, 2021, $6.5 billion of these sold loans 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 as of September 30, 2021 and $2 million as of December 31, 2020.

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 September 30, 2021 and December 31, 2020, there were $27 million and $36 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 September 30, 2021 and December 31, 2020, there were $26 million and $33 million, respectively, of such residential mortgage loans with credit risk recourse, upon which there have been negligible historical losses to the Corporation.

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 2020 Annual Report on Form 10-K.

The table below presents the Corporation’s financial instruments measured at fair value on a recurring basis as of September 30, 2021 and December 31, 2020, aggregated by the level in the fair value hierarchy within which those measurements fall:

The closing ratio on interest rate lock commitments to originate residential mortgage loans held for sale is a Level 3 measurement, and was 82% at September 30, 2021.

The following table presents the carrying value of equity securities without readily determinable fair values still held as of September 30, 2021 that are measured under the measurement alternative and the related adjustments recorded during the periods presented for those securities with observable price changes. These securities are included in the nonrecurring fair value tables when applicable price changes are observable. Also shown are the cumulative upward and downward adjustments for the Corporation's equity securities without readily determinable fair values as of September 30, 2021:

(b) If the fair value of the collateral exceeds the carrying amount of the asset, no charge off or adjustment is necessary, the asset is not considered to be carried at fair value, and is therefore not included in the table.
(c) Includes the full year impact on the consolidated statements of income
(d) When a property's value is written down at the time it is transferred to OREO, the charge off is booked to the provision for credit losses. When a property is already in OREO and subsequently written down, the charge off is booked to other noninterest expense.

Certain nonfinancial assets and nonfinancial liabilities measured at fair value on a nonrecurring basis include the fair value analysis in the goodwill impairment test as well as intangible assets and other nonfinancial long-lived assets measured at fair value for the purpose of impairment assessment.

The Corporation's significant Level 3 measurements which employ unobservable inputs that are readily quantifiable pertain to MSRs and individually evaluated loans.

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 First Staunton acquisition closed on February 14, 2020, and the employees who met the required criteria became eligible to participate in the RAP on February 15, 2020, with their vesting service credit based on their prior hours of service with First Staunton. See Note 2 for additional information on the First Staunton acquisition.

The components of net periodic pension cost and net periodic benefit cost for the RAP and Postretirement Plan for the three and nine months ended September 30, 2021 and 2020 were as follows:

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 nine months ended September 30, 2021 and 2020.

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 2020 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) 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.

A 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 2020 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 2020 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. In addition, until June 30, 2020, the Corporation offered insurance and risk consulting services. 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).

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.

(b) For the nine months ended September 30, 2021, the Corporation recognized a $2 million pre-tax gain on the sale of Whitnell.

(c) For the nine months ended September 30, 2020, the Corporation recognized a $163 million pre-tax gain on the sale of ABRC.

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

The Corporation has operating leases for retail and corporate offices, land, and equipment. The Corporation also has a finance lease for land.

These leases have original terms of 1 year or longer with remaining maturities up to 41 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:

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.

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.
