NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
September 30, 2020March 31, 2021 (Unaudited)

1. Principles of Consolidation and Presentation and Significant Accounting Policies
The accompanying consolidated financial statements include the accounts of Commerce Bancshares, Inc. and all majority-owned subsidiaries (the Company). Most of the Company's operations are conducted by its subsidiary bank, Commerce Bank (the Bank). The consolidated financial statements in this report have not been audited by an independent registered public accounting firm, but in the opinion of management, all adjustments necessary to present fairly the financial position and the results of operations for the interim periods have been made. All such adjustments are of a normal recurring nature. All significant intercompany accounts and transactions have been eliminated. Certain reclassifications were made to 20192020 data to conform to current year presentation. 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. Management has evaluated subsequent events for potential recognition or disclosure. The results of operations for the three and nine month periodsperiod ended September 30, 2020March 31, 2021 are not necessarily indicative of results to be attained for the full year or any other interim period.

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information and with the instructions to Form 10-Q adopted by the Securities and Exchange Commission. Accordingly, the financial statements do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Company's most recent Annual Report on Form 10-K, containing the latest audited consolidated financial statements and notes thereto.

On January 1, 2020, the Company adopted several FASB Accounting Standards Updates (ASUs). The Company's adoption of ASU 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, and its related amendments, resulted in changes to former accounting policies as described in Note 1 to the consolidated financial statements in the 2019 Annual Report on Form 10-K. Further discussion of the impact of adoption is included below, as well as in Note 2, Loans and Allowance for Credit Losses, and Note 3, Investment Securities. Significant accounting policies that were modified as a result of the adoption of ASU 2016-13 are included below.

The Company adopted ASU 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, and its related amendments on January 1, 2020. Known as the current expected credit loss (CECL), the standard replaced the incurred loss methodology. The new measurement approach requires the calculation of expected lifetime credit losses and is applied to financial assets measured at amortized cost, including loans and held-to-maturity securities, as well as certain off-balance sheet credit exposures such as unfunded lending commitments. The standard also changed the impairment model of available for sale debt securities.

The Company adopted CECL using the modified retrospective method for all financial assets measured at amortized cost and for unfunded lending commitments. Results for reporting periods beginning on or after January 1, 2020 are presented under CECL while prior period amounts continue to be reported in accordance with previously applicable GAAP. The Company recorded a net increase to retained earnings of $3.8 million as of January 1, 2020 for the cumulative effect of adopting CECL. The transition adjustment includes a decrease to the allowance for credit losses of $29.7 million related to the commercial loan portfolio, an increase to the allowance for credit losses of $8.7 million related to the personal banking loan portfolio, an increase to the liability for unfunded commitments of $16.1 million, and a tax impact of $1.2 million.

The following significant accounting policies have been updated since the Company's 2019 Annual Report on Form 10-K to reflect the adoption of ASU 2016-13.

Loans and Related Earnings
The Company's portfolio of held-for-investment loans includes a net investment in direct financing and sales type leases to commercial and industrial and tax-exempt entities, and collectively, the Company's portfolio of loans and leases is referred to as its "loan portfolio" or "loans". Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are reported at amortized cost, excluding accrued interest receivable. Amortized cost is the outstanding principal balance, net of any deferred fees and costs on originated loans. Origination fee income received on loans and amounts representing the estimated direct costs of origination are deferred and amortized to interest income over the life of the loan using the interest method. Loans are presented net of the allowance for credit losses on loans.
Interest on loans is accrued based upon the principal amount outstanding. The Company has elected the practical expedient to exclude all accrued interest receivable from all required disclosures of amortized cost. Additionally, an election was made not to measure an allowance for credit losses for accrued interest receivables. The Company has also made the election that all interest accrued but not received is reversed against interest income.
Loan and commitment fees, net of costs, are deferred and recognized in income over the term of the loan or commitment as an adjustment of yield. Annual fees charged on credit card loans are capitalized to principal and amortized over 12 months to loan fees and sales. Other credit card fees, such as cash advance fees and late payment fees, are recognized in income as an adjustment of yield when charged to the cardholder’s account.

Past Due Loans
Management reports loans as past due on the day following the contractual repayment date if payment was not received by end of the business day. Loans, or portions of loans, are charged off to the extent deemed uncollectible. Loan charge-offs reduce the allowance for credit losses on loans, and recoveries of loans previously charged off are added back to the allowance. Business, business real estate, construction and land real estate, and personal real estate loans are generally charged down to estimated collectible balances when they are placed on non-accrual status. Consumer loans and related accrued interest are normally charged down to the fair value of related collateral (or are charged off in full if not collateralized) once the loans are more than 120 to 180 days delinquent, depending on the type of loan. Revolving home equity loans are charged down to the fair value of the related collateral once the loans are more than 180 days past due. Credit card loans are charged off against the allowance for credit losses when the receivable is more than 180 days past due.

Troubled Debt Restructurings
A loan is accounted for as a troubled debt restructuring if the Company, for economic or legal reasons related to the borrower's financial difficulties, grants a concession to the borrower that it would not otherwise consider. A troubled debt restructuring typically involves (1) modification of terms such as a reduction of the stated interest rate, loan principal, or accrued interest, (2) a loan renewal at a stated interest rate lower than the current market rate for a new loan with similar risk, or (3) debt that was not reaffirmed in bankruptcy. Business, business real estate, construction and land real estate and personal real estate troubled debt restructurings with impairment charges are placed on non-accrual status. The Company measures the impairment loss of a troubled debt restructuring at the time of modification based on the present value of expected future cash flows. Subsequent to modification, troubled debt restructurings are subject to the Company’s allowance for credit loss model, which is discussed below and in Note 2, Loans and Allowance for Credit Losses. Troubled debt restructurings that are performing under their contractual terms continue to accrue interest, which is recognized in current earnings.
Section 4013 of the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act") was signed into law on March 27, 2020 and provides financial institutions the option to suspend the requirement to categorize certain modifications related to the global Coronavirus Disease 2019 (COVID-19) pandemic as troubled debt restructurings. Additionally, bank regulatory agencies issued additional guidance on implementing the provisions of the CARES Act. The Company follows the guidance under the CARES Act. Refer to Note 2 for additional information.

Allowance for Credit Losses on Loans
The allowance for credit losses on loans is a valuation amount that is deducted from the amortized cost basis of loans not held at fair value to present the net amount expected to be collected over the contractual term of the loans. The allowance for credit losses on loans is measured using relevant information about past events, including historical credit loss experience on loans with similar risk characteristics, current conditions, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual term of the loans. An allowance will be created upon origination or acquisition of a loan and is updated at subsequent reporting dates. The methodology is applied consistently for each reporting period and reflects management’s current expectations of credit losses. Changes to the allowance for credit losses on loans resulting from periodic evaluations are recorded through increases or decreases to the credit loss expense for loans, which is recorded in provision for credit losses on the consolidated statements of income. Loans that are deemed to be uncollectible are charged off against the related allowance for credit losses on loans.
The allowance for credit losses on loans is measured on a collective (pool) basis. Loans are aggregated into pools based on similar risk characteristics including borrower type, collateral type and expected credit loss patterns. The allowance for credit losses on a troubled debt restructuring which continues to accrue interest is also measured on a collective basis. Loans that do not share similar risk characteristics, primarily large loans on non-accrual status, are evaluated on an individual basis. The allowance related to these large non-accrual loans is measured using the fair value of the collateral (less selling cost, if applicable) as most of these loans are collateral dependent and the borrower is facing financial difficulty.
As noted above, the allowance for credit losses on loans does not include an allowance for accrued interest.

Liability for Unfunded Lending Commitments
The Company’s unfunded lending commitments are primarily unfunded loan commitments and letters of credit. Expected credit losses for these unfunded lending commitments are calculated over the contractual period during which the Company is exposed to the credit risk. The methodology used to measure credit losses for unfunded lending commitments is the same as the methodology used for loans, however, the estimate of credit risk for unfunded lending commitments takes into consideration the likelihood that funding will occur. The liability for unfunded lending commitments excludes any exposures that are unconditionally cancellable by the Company. The loss estimate is recorded within other liabilities on the consolidated balance sheet. Changes to the liability for unfunded lending commitments are recorded through increases or decreases to the provision for credit losses on the consolidated statements of income.

Investments in Debt and Equity Securities
The majority of the Company's investment portfolio is comprised of debt securities that are classified as available for sale. From time to time, the Company sells securities and utilizes the proceeds to reduce borrowings, fund loan growth, or modify its interest rate profile. Securities classified as available for sale are carried at fair value. Changes in fair value are reported in other comprehensive income (loss), a component of stockholders’ equity. Securities are periodically evaluated for credit losses in accordance with the guidance provided in ASC 326. Further discussion of this evaluation is provided in "Allowance for Credit Losses on Available for Sale Debt Securities" below. Gains and losses realized upon sales of securities are calculated using the specific identification method and are included in investment securities gains (losses), net, in the consolidated statements of income. Purchase premiums and discounts are amortized to interest income using a level yield method over the
11

Table of Contents


estimated lives of the securities. For certain callable debt securities purchased at a premium, the amortization is instead recorded to the earliest call date. For mortgage and asset-backed securities, prepayment experience is evaluated quarterly to determine if a change in a bond's estimated remaining life is necessary. A corresponding adjustment is then made in the related amortization of premium or discount accretion.

Accrued interest receivable on available for sale debt securities is reported in other assets on the consolidated balance sheet. The Company has elected the practical expedient to exclude the accrued interest from all required disclosures of amortized cost. Additionally, an election was made not to measure an allowance for credit losses for accrued interest receivables. Interest accrued but not received is reversed against interest income.

Equity securities include common and preferred stock with readily determinable fair values. These are also carried at fair value. Certain equity securities do not have readily determinable fair values. The Company has elected under ASU 2016-01 to measure these equity securities without a readily determinable fair value at cost minus impairment, if any, plus or minus changes resulting from observable price changes for the identical or similar investment of the same issuer. The Company has not recorded any impairment or other adjustments to the carrying amount of these equity investments without readily determinable fair values.

Other securities include Federal Reserve Bank stock and Federal Home Loan Bank stock, which are held for debt and regulatory purposes. They are carried at cost and periodically evaluated for impairment. Also included are investments in portfolio concerns held by the Company’s private equity subsidiaries, which consist of both debt and equity instruments. Private equity investments are carried at fair value in accordance with ASC 946-10-15, with changes in fair value reported in current earnings. In the absence of readily ascertainable market values, fair value is estimated using internally developed methods. Changes in fair value which are recognized in current earnings and gains and losses from sales are included in investment securities gains (losses), net in the consolidated statements of income.

Trading account securities, which are debt securities bought and held principally for the purpose of resale in the near term, are carried at fair value. Gains and losses, both realized and unrealized, are recorded in non-interest income.

Purchases and sales of securities are recognized on a trade date basis. A receivable or payable is recognized for pending transaction settlements.

Allowance for Credit Losses on Available for Sale Debt Securities
For available for sale debt securities in an unrealized loss position, the entire loss in fair value is required to be recognized in current earnings if the Company intends to sell the securities or believes it more likely than not that it will be required to sell the security before the anticipated recovery. If neither condition is met, and the Company does not expect to recover the amortized cost basis, the Company determines whether the decline in fair value resulted from credit losses or other factors. If the assessment indicates that a credit loss exists, the present value of cash flows expected to be collected is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss has occurred, and an allowance for credit losses is recorded. The allowance for credit losses is limited by the amount that the fair value is less than the amortized cost basis. Any impairment not recorded through the provision for credit losses is recognized in other comprehensive income.

Changes in the allowance for credit losses are recorded as a provision for (or reversal of) credit losses on the consolidated statements of income. Losses are charged against the allowance for credit losses on securities when management believes the uncollectibility of an available for sale security is confirmed or when either of the conditions regarding intent or requirement to sell is met.

Accrued interest receivable on available for sale debt securities is excluded from the estimate of credit losses.

Allowance for credit losses
The allowance for credit losses is measured using an average historical loss model which incorporates relevant information about past events including(including historical credit loss experience on loans with similar risk characteristics,characteristics), current conditions, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual term of the loans. The allowance for credit losses is measured on a collective (pool) basis. Loans are aggregated into pools based on similar risk characteristics including borrower type, collateral type and expected credit loss patterns. Loans that do not share similar risk characteristics, primarily large loans on non-accrual status, are evaluated on an individual basis.

For loans evaluated for credit losses on a collective basis, average historical loss rates are calculated for each pool using the Company’s historical net charge-offs (combined charge-offs and recoveries by observable historical reporting period) and outstanding loan balances during a lookback period. Lookback periods can be different based on the individual pool and represent management’s credit expectations for the pool of loans over the remaining contractual life. In certain loan pools, if the Company’s own historical loss rate is not reflective of the loss expectations, the historical loss rate is augmented by industry and peer data. The calculated average net charge-off rate is then adjusted for current conditions and reasonable and supportable forecasts. These adjustments increase or decrease the average historical loss rate to reflect expectations of future losses given a single path economic forecast of key macroeconomic variables including GDP, disposable income, unemployment rate, various interest rates, CPI inflation rate, HPI, CREPI and market volatility. The adjustments are based on results from various regression models projecting the impact of the macroeconomic variables to loss rates. The forecast is used for a reasonable and supportable period before reverting back to historical averages using a straight-line method. The forecast adjusted loss rate is applied to the amortized cost of loans over the remaining contractual lives, adjusted for expected prepayments. The contractual term excludes expected extensions (except for contractual extensions at the option of the customer), renewals and modifications unless there is a reasonable expectation that a troubled debt restructuring will be executed. Credit cards and certain similar consumer lines of credit do not have stated maturities and therefore, for these loan classes, remaining contractual lives are determined by estimating future cash flows expected to be received from customers until payments have been fully allocated to outstanding balances. Additionally, the allowance for credit losses considers other qualitative factors not included in historical loss rates or macroeconomic forecast such as changes in portfolio composition, underwriting practices, or significant unique events or conditions.

The liability for unfunded lending commitments utilizes the same model as the allowance for credit losses on loans, however, the liability for unfunded lending commitments incorporates an assumption for the portion of unfunded commitments that are expected to be funded.

Sensitivity in the Allowance for Credit Loss model
The allowance for credit losses is an estimate that requires significant judgment including projections of the macro-economic environment. The forecasted macro-economic environment continuously changes which can cause fluctuations in estimated expected losses.

The current forecast projects a sharp recession with acontinued recovery in the next two years as a result of the COVID-19 outbreak.pandemic induced recession. This pandemic is unprecedented and information that could be used in the estimation of the allowance for credit losses changes frequently. Events such asTrends in health conditions and vaccine distribution could significantly modify economic projections used in the timingestimation of governmental required business lock downs or possible additional waves of infection could prolong and deepen the projected recession.allowance for credit losses.

Credit quality indicators
The following table provides information about the credit quality of the Commercial loan portfolio. The Company utilizes an internal risk rating system comprised of a series of grades to categorize loans according to perceived risk associated with the expectation of debt repayment based on borrower specific information including but not limited to current financial information, historical payment experience, industry information, collateral levels and collateral types. The “pass” category consists of a range of loan grades that reflect increasing, though still acceptable, risk. A loan is assigned the risk rating at origination and then monitored throughout the contractual term for possible risk rating changes. Movement of risk through the various grade levels in the “pass” category is monitored for early identification of credit deterioration. The “special mention” rating is applied to loans where the borrower exhibits negative financial trends due to borrower specific or systemic conditions that, if left uncorrected, threaten its capacity to meet its debt obligations. The borrower is believed to have sufficient financial flexibility to react to and resolve its negative financial situation. It is a transitional grade that is closely monitored for improvement or deterioration. The “substandard” rating is applied to loans where the borrower exhibits well-defined weaknesses that jeopardize its continued performance and are of a severity that the distinct possibility of default exists. Loans are placed on “non-accrual” when management does not expect to collect payments consistent with acceptable and agreed upon terms of repayment.

All loans are analyzed for risk rating updates annually. For larger loans, rating assessments may be more frequent if relevant information is obtained earlier through debt covenant monitoring or overall relationship management. Smaller loans

are monitored as identified by the loan officer based on the risk profile of the individual borrower or if the loan becomes past

due related to credit issues. Loans rated Special Mention, Substandard or Non-accrual are subject to quarterly review and monitoring processes. In addition to the regular monitoring performed by the lending personnel and credit committees, loans are subject to review by a credit review department which verifies the appropriateness of the risk ratings for the loans chosen as part of its risk-based review plan.

The risk category of loans in the Commercial portfolio as of September 30,March 31, 2021 and December 31, 2020 are as follows:

Other Personal Banking loan information
As noted above, the credit quality of Personal Banking loans is monitored primarily on the basis of aging/delinquency, and this information is provided in the table in the above section on "Credit quality indicators." In addition, FICO scores are obtained and updated on a quarterly basis for most of the loans in the Personal Banking portfolio. This is a published credit score designed to measure the risk of default by taking into account various factors from a borrower's financial history and is considered supplementary information utilized by the Company, as management does not consider this information in evaluating the allowance for credit losses on loans. The Bank normally obtains a FICO score at the loan's origination and renewal dates, and updates are obtained on a quarterly basis. Excluded from the table below are certain personal real estate loans for which FICO scores are not obtained because the loans generally pertain to commercial customer activities and are often underwritten with other collateral considerations. These loans totaled $183.3$188.6 million at September 30, 2020March 31, 2021 and $198.2$191.1 million at December 31, 2019.2020. The table also excludes consumer loans related to the Company's patient healthcare loan program, which totaled $193.2$179.8 million at September 30, 2020March 31, 2021 and $199.2$188.1 million at December 31, 2019.2020. As the healthcare loans are guaranteed by the hospital, customer FICO scores are not obtained for these loans. The personal real estate loans and consumer loans excluded below totaled less than 7% of the Personal Banking portfolio. For the remainder of loans in the Personal Banking portfolio, the table below shows the percentage of balances outstanding at September 30, 2020March 31, 2021 and December 31, 20192020 by FICO score.

Troubled debt restructurings
Restructured loans are those extended to borrowers who are experiencing financial difficulty and who have been granted a concession. Restructured loans are placed on non-accrual status if the Company does not believe it probable that amounts due under the contractual terms will be collected. Commercial performing restructured loans are primarily comprised of certain business, construction and business real estate loans classified as substandard but renewed at rates judged to be non-market. These loans are performing in accordance with their modified terms, and because the Company believes it probable that all amounts due under the modified terms of the agreements will be collected, interest on these loans is being recognized on an accrual basis. Troubled debt restructurings also include certain credit card and other small consumer loans under various debt management and assistance programs. Modifications to these loans generally involve removing the available line of credit, placing loans on amortizing status, and lowering the contractual interest rate. Certain personal real estate, revolving home equity, and consumer loans were classified as consumer bankruptcy troubled debt restructurings because they were not reaffirmed by the borrower in bankruptcy proceedings. Interest on these loans is being recognized on an accrual basis, as the borrowers are continuing to make payments. Other consumer loans classified as troubled debt restructurings consist of various other workout arrangements with consumer customers.

Section 4013 of the CARES Act was signed into law on March 27, 2020, and includes a provision that short-term modifications are not troubled debt restructurings, if made on a good-faith basis in response to COVID-19 to borrowers who were current prior to December 31, 2019. In addition to the CARES Act, bank regulatory agencies issued interagency guidance stating suspending the troubled debt restructuring classification would be appropriate if the borrower was less than 30 days past due at the time the modification program is implemented. The guidance also provides that loans generally will not be adversely classified if the short-term modification is related to COVID-19 relief programs. The Company follows the guidance under the CARES Act when determining if a customer’s modification is subject to troubled debt restructuring classification. If it is deemed the modification is not short-term, not COVID-19 related or the customer does not meet the criteria under the guidance to be scoped out of troubled debt restructuring classification, the Company will evaluate the loan modifications under its existing framework which requires modifications that result in a concession to a borrower experiencing financial difficulty be accounted for as a troubled debt restructuring.

The initial guidance issued under the CARES Act was due to expire on December 31, 2020. During January 2021, the Consolidated Appropriations Act, 2021 was enacted and extended relief offered under the CARES Act related to the accounting and disclosure requirements for troubled debt restructurings as a result of COVID-19. The Company elected to adopt the extension of this guidance.

Table of Contents
For those loans on non-accrual status also classified as restructured, the modification did not create any further financial effect on the Company as those loans were already recorded at net realizable value. For those performing commercial loans classified as restructured, there were no concessions involving forgiveness of principal or interest and, therefore, there was no financial impact to the Company as a result of modification to these loans. No financial impact resulted from those performing loans where the debt was not reaffirmed in bankruptcy, as no changes to loan terms occurred in that process. However, the effects of modifications to loans under various debt management and assistance programs were estimated to decrease interest income by approximately $1.1$1.0 million on an annual, pre-tax basis, compared to amounts contractually owed. Other modifications to consumer loans mainly involve extensions and other small modifications that did not include the forgiveness of principal or interest.

The allowance for credit losses related to troubled debt restructurings on non-accrual status is determined by individual evaluation, including collateral adequacy, using the same process as loans on non-accrual status which are not classified as troubled debt restructurings. Those performing loans classified as troubled debt restructurings are accruing loans which

management expects to collect under contractual terms. Performing commercial loans having no other concessions granted other than being renewed at non-market interest rates are judged to have similar risk characteristics as non-troubled debt commercial loans and are collectively evaluated based on internal risk rating, loan type, delinquency, historical experience and current economic factors. Performing personal banking loans classified as troubled debt restructurings resulted from the borrower not reaffirming the debt during bankruptcy and have had no other concession granted, other than the Bank's future limitations on collecting payment deficiencies or in pursuing foreclosure actions. As such, they have similar risk characteristics as non-troubled debt personal banking loans and are evaluated collectively based on loan type, delinquency, historical experience and current economic factors.

If a troubled debt restructuring defaults and is already on non-accrual status, the allowance for credit losses continues to be based on individual evaluation, using discounted expected cash flows or the fair value of collateral. If an accruing troubled debt restructuring defaults, the loan's risk rating is downgraded to non-accrual status and the loan's related allowance for credit losses is determined based on individual evaluation, or if necessary, the loan is charged off and collection efforts begun.begin.

Allowance for credit losses on available for sale debt securities
As described in Note 1, theThe Company adopted ASU 2016-13, Measurement of Credit Losses on Financial Instruments, on January 1, 2020. The adoption of ASU 2016-13 had no impact to the Company's available for sale securities reported in its consolidated financial statements at January 1, 2020. For the three and nine months ended September 30,March 31, 2021 and 2020, the Company did not recognize a credit loss expense on any available for sale debt securities.

The Company’s impairment policy requires a reviewmodel for establishing its allowance for credit losses uses cash flows projected to be received over the estimated life of allthe securities, discounted to present value, and compared to the current amortized cost bases of the securities. Securities for which fair value is less than amortized cost.cost are reviewed for impairment. Special emphasis is placed on securities whose credit rating has fallen below Baa3 (Moody's) or BBB- (Standard & Poor's), whose fair values have fallen more than 20% below purchase price, or who have been identified based on management’s judgment. These securities are placed on a watch list and cash flow analyses are prepared on an individual security basis. Inputs to these models includeCredit impairment is determined using input factors such as cash flow projections, contractual payments required, expected delinquency rates, credit support from other tranches, prepayment speeds, collateral loss severity rates (including loan to values), and various other information related to the underlying collateral. Stress tests are performed at varying levels of delinquency rates, prepayment speeds and loss severities in order to gauge probable ranges of credit loss. At September 30, 2020,March 31, 2021, the fair value of securities on this watch list was $53.3$25.6 million compared to $51.6$31.0 million at December 31, 2019.

The table below summarizes debt securities available for sale in an unrealized loss position, aggregated by length of loss period, for which an allowance for credit losses has not been recorded at September 30,March 31, 2021 and December 31, 2020. Unrealized losses on these available for sale securities have not been recognized into income because after review, the issuers' bondssecurities were deemed not to be impaired. The unrealized losses on these securities are of investment grade quality (rated Baa3, BBB- or higher), their fair values have not fallen more than 20% below purchase price,primarily attributable to changes in interest rates and they have not been identified by management as a security needing a more detailed review.current market conditions. Additionally, management does not intend to sell the securities, and it is more likely than not that management will not be required to sell the securities prior to their anticipated recovery. The cash flow analyses prepared for securities included on the watch list discussed above did not identify any instances where the present value of expected cash flows were less than the amortized cost basis of the security.

5. Guarantees
The Company, as a provider of financial services, routinely issues financial guarantees in the form of financial and performance standby letters of credit. Standby letters of credit are contingent commitments issued by the Company generally to guarantee the payment or performance obligation of a customer to a third party. While these represent a potential outlay by the Company, a significant amount of the commitments may expire without being drawn upon. The Company has recourse against the customer for any amount it is required to pay to a third party under a standby letter of credit. The letters of credit are subject to the same credit policies, underwriting standards and approval process as loans made by the Company. Most of the standby letters of credit are secured, and in the event of nonperformance by customers, the Company has rights to the underlying collateral, which could include commercial real estate, physical plant and property, inventory, receivables, cash and marketable securities.

Upon issuance of standby letters of credit, the Company recognizes a liability for the fair value of the obligation undertaken, which is estimated to be equivalent to the amount of fees received from the customer over the life of the agreement. At September 30, 2020,March 31, 2021, that net liability was $3.3$3.0 million, which will be accreted into income over the remaining life of the respective commitments. The contractual amount of these letters of credit, which represents the maximum potential future payments guaranteed by the Company, was $318.0$440.4 million at September 30, 2020.March 31, 2021.

Table of Contents
The Company periodically enters into credit risk participation agreements (RPAs) as a guarantor to other financial institutions, in order to mitigate those institutions’ credit risk associated with interest rate swaps with third parties. The RPA stipulates that, in the event of default by the third party on the interest rate swap, the Company will reimburse a portion of the loss borne by the financial institution. These interest rate swaps are normally collateralized (generally with real property, inventories and equipment) by the third party, which limits the credit risk associated with the Company’s RPAs. The third parties usually have other borrowing relationships with the Company. The Company monitors overall borrower collateral and at September 30, 2020,March 31, 2021, believes sufficient collateral is available to cover potential swap losses. The RPAs are carried at fair value throughout their term with all changes in fair value, including those due to a change in the third party’s creditworthiness, recorded in current earnings. The terms of the RPAs, which correspond to the terms of the underlying swaps, range from 2 years to 11 years. At September 30, 2020,March 31, 2021, the fair value of the Company's guarantee liabilities for RPAs was $1.2 million,$339 thousand, and the notional amount of the underlying swaps was $272.8$272.0 million. The maximum potential future payment guaranteed by the Company cannot be readily estimated but is dependent upon the fair value of the interest rate swaps at the time of default.

Presented below is a summary of the components used to calculate basic and diluted income per share. The Company applies the two-class method of computing income per share, as nonvested share-based awards that containpay nonforfeitable rights tocommon stock dividends are considered securities which participate in undistributed earnings with common stock. The two-class method requires the calculation of separate income per share amounts for the nonvested share-based awards and for common stock. Income per share attributable to common stock is shown in the table below. Nonvested share-based awards are further discussed in Note 13.

On September 1, 2020, the Company redeemed all outstanding shares of its 6.00% Series B Non-Cumulative Perpetual Preferred Stock, $1.00 par value per share (Series B Preferred Stock) and the corresponding depositary shares representing fractional interests in the Series B Preferred Stock (Series B Depositary Shares). The 6,000,000 depositary shares, each representing a 1/1,000th interest in a share of Series B Preferred Stock, were redeemed simultaneously with the redemption of the Series B Preferred Stock at a redemption price of $25 per depositary share. Regular dividends on the outstanding shares of the Series B Preferred Stock were paid separately on September 1, 2020 to all holders of record as of August 14, 2020, in the customary manner, and future dividends ceased to accrue. For the nine month period ended September 30, 2020, preferred stock dividends totaled $12.0 million, and included $5.2 million related to the preferred stock redemption, which is the excess of the redemption costs over the book value of the preferred stock.

9. Accumulated Other Comprehensive Income
The table below shows the activity and accumulated balances for components of other comprehensive income. The largest component is the unrealized holding gains and losses on available for sale debt securities. Another component is the amortization from other comprehensive income of losses associated with pension benefits, which occurs as the losses are included in current net periodic pension cost. The remaining component is gains and losses in fair value on certain interest rate floors that have been designated as cash flow hedging instruments. The interest rate floors were terminated during 2020, and the realized gains will be amortized into interest income through the original maturity dates of the interest rate floors. Information about unrealized gains and losses on securities can be found in Note 3, and information about unrealized gains and losses on cash flow hedge derivatives is located in Note 11.

The Company adopted ASU 2016-13 (CECL) on January 1, 2020, which changed the impairment model for available for sale debt securities. The new standard requires an allowance for credit losses when the present value of the cash flows expected to be collected is less than the security's amortized cost basis. See further discussion of the Company's CECL adoption in Note 1 and Note 3 to the consolidated financial statements. Further, the new standard superceded the guidance related to other-than-temporary impairment (OTTI), including the requirement to separately disclose the unrealized gains and losses on securities with OTTI. Prior to the Company's adoption of CECL, unrealized gains and losses on debt securities for which an OTTI has been recorded in current earnings were shown separately below. As a result of adopting CECL, the table below will separately disclose unrealized gains and losses on debt securities for which an allowance for credit losses has been recorded. During the first nine months of 2020, there were no securities for which an allowance for credit losses was recorded.

The information presented above was derived from the internal profitability reporting system used by management to monitor and manage the financial performance of the Company. This information is based on internal management accounting procedures and methods, which have been developed to reflect the underlying economics of the businesses. The methodologies are applied in connection with funds transfer pricing and assignment of overhead costs among segments. Funds transfer pricing was used in the determination of net interest income by assigning a standard cost (credit) for funds used (provided) by(provided by) assets and liabilities based on their maturity, prepayment and/or repricing characteristics.

The segment activity, as shown above, includes both direct and allocated items. Amounts in the “Other/Elimination” column include activity not related to the segments, such as that relating to administrative functions, the investment securities portfolio, and the effect of certain expense allocations to the segments. The provision for credit losses in this category contains the difference between net loan charge-offs assigned directly to the segments and the recorded provision for credit loss expense. Included in this category’s net interest income are earnings of the investment portfolio, which are not allocated to a segment.

The performance measurement of the operating segments is based on the management structure of the Company and is not necessarily comparable with similar information for any other financial institution. The information is also not necessarily indicative of the segments' financial condition and results of operations if they were independent entities.

11. Derivative Instruments
The notional amounts of the Company’s derivative instruments are shown in the table below. These contractual amounts, along with other terms of the derivative, are used to determine amounts to be exchanged between counterparties and are not a measure of loss exposure. At September 30, 2020, with the exception of the interest rate floor (discussed below),March 31, 2021, the Company’s derivative instruments are accounted for as free-standing derivatives, and changes in their fair value are recorded in current earnings.

The largest group of notional amounts relate to interest rate swap contracts sold to commercial customers who wish to modify their interest rate sensitivity. The customers are engaged in a variety of businesses, including real estate, manufacturing, retail product distribution, education, and retirement communities. These customer swaps are offset by matching contracts purchased by the Company from other financial dealer institutions. Contracts with dealers that require central clearing are novated to a clearing agency who becomes the Company's counterparty. Because of the matching terms of the offsetting contracts, in addition to collateral provisions which mitigate the impact of non-performance risk, changes in fair value subsequent to initial recognition have a minimal effect on earnings.

Many of the Company’s interest rate swap contracts with large financial institutions contain contingent features relating to debt ratings or capitalization levels. Under these provisions, if the Company’s debt rating falls below investment grade or if the Company ceases to be “well-capitalized” under risk-based capital guidelines, certain counterparties can require immediate and ongoing collateralization on interest rate swaps in net liability positions or instant settlement of the contracts. The Company maintains debt ratings and capital well above these minimum requirements.

As of September 30, 2020, the Company has entered into one interest rate floor with a notional value of $500.0 million, to hedge the risk of declining interest rates on certain floating rate commercial loans indexed to one month LIBOR. The interest rate floor has a purchased strike rate of 2.00% and is effective on December 15, 2020 and matures on December 15, 2026. The premium paid for the floor totaled $10.7 million. As of September 30, 2020, the maximum length of time over which the Company is hedging its exposure to the variability in future cash flows is approximately 6.2 years. The interest rate floor qualified and was designated as a cash flow hedge, and was assessed for effectiveness using regression analysis. The change in the fair value of the interest rate floor is recorded in AOCI, net of the amortization of the premium paid, which is recorded against interest and fees on loans in the consolidated statements of income. As of September 30, 2020, net deferred gains on the interest rate floor totaled $38.7 million (pre-tax) and was recorded in AOCI in the consolidated balance sheet. As of September 30, 2020, it is expected that $1.4 million (pre-tax) of interest rate floor premium amortization will be reclassified from AOCI into earnings over the next twelve months.

During the quarteryear ended September 30,December 31, 2020, the Company monetized twothree interest rate floors that were previously classified as cash flow hedges with a combined notional balance of $1.0$1.5 billion and an asset fair value of $115.9$163.2 million. As of September 30, 2020,March 31, 2021, the total unrealizedrealized gains on the monetized cash flow hedges remaining in AOCI was $90.4$117.7 million (pre-tax). The unrealized gains will be reclassified into interest income as the underlying forecasted transactions impact earnings through the original maturity dates of the hedged forecasted transactions, or approximately 5.7 years.

In October 2020, the Company monetized the above interest rate floor that is effective on December 15, 2020 and will amortize a gain of $37.6 million into earnings through December 15, 2026, the original maturity date.

The Company also contracts with other financial institutions, as a guarantor or beneficiary, to share credit risk associated with certain interest rate swaps through risk participation agreements. The Company’s risks and responsibilities as guarantor are further discussed in Note 5 on Guarantees. In addition, the Company enters into foreign exchange contracts, which are mainly comprised of contracts to purchase or deliver foreign currencies for customers at specific future dates.

Under its program to sell residential mortgage loans in the secondary market, the Company designates certain newly-originated residential mortgage loans as held for sale. Derivative instruments arising from this activity include mortgage loan commitments and forward loan sale contracts. Changes in the fair values of the loan commitments and funded loans prior to sale that are due to changes in interest rates are economically hedged with forward contracts to sell residential mortgage-backed securities in the to-be-announced (TBA) market. These forward TBA contracts are also considered to be derivatives and are settled in cash at the security settlement date.

The fair values of the Company's derivative instruments, whose notional amounts are listed above, are shown in the table below. Information about the valuation methods used to determine fair value is provided in Note 17 on Fair Value Measurements in the 20192020 Annual Report on Form 10-K.

The Company's policy is to present its derivative assets and derivative liabilities on a gross basis in its consolidated balance sheets and these are reported in other assets and other liabilities. Certain collateral posted to and from the Company's clearing counterparty has been applied to the fair values of the cleared swaps, such that at September 30, 2020March 31, 2021 in the table below, the positive fair values of cleared swaps were reduced by $312 thousand and the negative fair values of cleared swaps were reduced by $46.9 million. At December 31, 2020, there were 0 reductions to the positive fair values of cleared swaps and the negative fair values of cleared swaps were reduced by $77.8 million. At December 31, 2019, the positive fair values of cleared swaps were reduced by $617 thousand and the negative fair values of cleared swaps were reduced by $28.5$69.2 million.

Also shown is collateral received or pledged in the form of other financial instruments, which is generally cash or marketable securities. The collateral amounts in this table are limited to the outstanding balances of the related asset or liability (after netting is applied); thus, amounts of excess collateral are not shown. Most of the derivatives in the following table were transacted under master netting arrangements that contain a conditional right of offset, such as close-out netting, upon default.

its swap derivative counterparties, the Company does not offset derivative assets and liabilities under these agreements on its consolidated balance sheet. Collateral exchanged between the Company and dealer bank counterparties is generally subject to thresholds and transfer minimums, and usually consists of marketable securities. By contract, these may be sold or re-pledged by the secured party until recalled at a subsequent valuation date by the pledging party. For those swap transactions requiring central clearing, the Company posts cash or securities to its clearing agent. Collateral positions are valued daily, and adjustments to amounts received and pledged by the Company are made as appropriate to maintain proper collateralization for these transactions. Swap derivative transactions with customers are generally secured by rights to non-financial collateral, such as real and personal property, which is not shown in the table below.

12. Resale and Repurchase Agreements
The following table shows the extent to which assets and liabilities relating to securities purchased under agreements to resell (resale agreements) and securities sold under agreements to repurchase (repurchase agreements) have been offset in the consolidated balance sheets, in addition to the extent to which they could potentially be offset. Also shown is collateral received or pledged, which consists of marketable securities. The collateral amounts in the table are limited to the outstanding balances of the related asset or liability (after netting is applied); thus, amounts of excess collateral are not shown. The agreements in the following table were transacted under master netting arrangements that contain a conditional right of offset, such as close-out netting, upon default.

Resale and repurchase agreements are agreements to purchase/sell securities subject to an obligation to resell/repurchase the same or similar securities. They are accounted for as collateralized financing transactions, not as sales and purchases of the securities portfolio. The securities collateral accepted or pledged in resale and repurchase agreements with other financial institutions also may be sold or re-pledged by the secured party but is usually delivered to and held by third party trustees. The Company generally retains custody of securities pledged for repurchase agreements with customers.

Table of Contents
The Company is party to agreements commonly known as collateral swaps. These agreements involve the exchange of collateral under simultaneous repurchase and resale agreements with the same financial institution counterparty. These repurchase and resale agreements have the same principal amounts, inception dates, and maturity dates and have been offset against each other in the consolidated balance sheets, as permitted under the netting provisions of ASC 210-20-45. The collateral swaps totaled $200.0 million at September 30, 2020March 31, 2021 and December 31, 2019.2020. At September 30, 2020,March 31, 2021, the Company had posted collateral of $209.6$203.2 million in marketable securities, consisting of agency mortgage-backed bonds, and had accepted $209.0$209.3 million in agency mortgage-backed bonds.

13. Stock-Based Compensation
The Company issues stock-based compensation in the form of nonvested restricted stock and stock appreciation rights (SARs). Most of the awards are issued during the first quarter of each year. The stock-based compensation expense that has been charged against income was $3.8$3.9 million and $3.5$3.7 million in the three months ended September 30,March 31, 2021 and 2020, and 2019, respectively, and $11.2 million and $10.4 million in the nine months ended September 30, 2020 and 2019, respectively.

Nonvested stock awards granted generally vest in 4 to 7 years and contain restrictions as to transferability, sale, pledging, or assigning, among others, prior to the end of the vesting period. Dividend and voting rights are conferred upon grant. A summary of the status of the Company’s nonvested share awards as of September 30, 2020,March 31, 2021, and changes during the ninethree month period then ended, is presented below.

14. Revenue from Contracts with Customers
The core principle of ASU 2014-09, "Revenue from Contracts with Customers," is that an entity should recognize revenue to reflect the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. For the ninethree months ended September 30, 2020,March 31, 2021, approximately 63%60% of the Company’s total revenue was comprised of net interest income, which is not within the scope of this guidance. Of the remaining revenue, those items that were subject to this guidance mainly included fees for bank card, trust, deposit account services and consumer brokerage services.

For bank card transaction fees, the majority of debit and credit card fees are earned in the Consumer segment, while corporate card and merchant fees are earned in the Commercial segment. The Consumer and Commercial segments each contribute approximately half of the Company's deposit account charge revenue. All trust fees and nearly all of the consumer brokerage services income are earned in the Wealth segment.

15. Fair Value Measurements
The Company uses fair value measurements to record fair value adjustments to certain financial and nonfinancial assets and liabilities and to determine fair value disclosures. Various financial instruments such as available for sale debt securities, equity securities, trading debt securities, certain investments relating to private equity activities, and derivatives are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets and liabilities on a nonrecurring basis, such as mortgage servicing rights and certain other investment securities. These nonrecurring fair value adjustments typically involve lower of cost or fair value accounting or write-downs of individual assets.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, the Company uses various valuation techniques and assumptions when estimating fair value. For accounting disclosure purposes, a three-level valuation hierarchy of fair value measurements has been established. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows:
Level 1 – inputs to the valuation methodology are quoted prices for identical assets or liabilities in active markets.
Level 2 – inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, and inputs that are observable for the assets or liabilities, either directly or indirectly (such as interest rates, yield curves, and prepayment speeds).
Level 3 – inputs to the valuation methodology are unobservable and significant to the fair value. These may be internally developed, using the Company’s best information and assumptions that a market participant would consider.
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 Company's 20192020 Annual Report on Form 10-K. There have been no significant changes in these methodologies since then.

16. Fair Value of Financial Instruments
The carrying amounts and estimated fair values of financial instruments held by the Company are set forth below. Fair value estimates are made at a specific point in time based on relevant market information. They do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for many of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, risk characteristics and economic conditions. These estimates are subjective, involve uncertainties, and cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Table of Contents
The estimated fair values of the Company’s financial instruments and the classification of their fair value measurement within the valuation hierarchy are as follows at September 30, 2020March 31, 2021 and December 31, 2019:2020:

Forward-Looking Information
This report may contain "forward-looking statements" that are subject to risks and uncertainties and include information about possible or assumed future results of operations. Many possible events or factors could affect the future financial results and performance of the Company. This could cause results or performance to differ materially from those expressed in the forward-looking statements. Words such as "expects", "anticipates", "believes", "estimates", variations of such words and other similar expressions are intended to identify such forward-looking statements. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict. Therefore, actual outcomes and results may differ materially from what is expressed or forecasted in, or implied by, such forward-looking statements. Readers should not rely solely on the forward-looking statements and should consider all uncertainties and risks discussed throughout this report. Forward-looking statements speak only as of the date they are made. The Company does not undertake to update forward-looking statements to reflect circumstances or events that occur after the date the forward-looking statements are made or to reflect the occurrence of unanticipated events. Such possible events or factors include: changes in economic conditions in the Company's market area, the effects of the COVID-19 pandemic, changes in policies by regulatory agencies, governmental legislation and regulation, fluctuations in interest rates, changes in liquidity requirements, demand for loans in the Company's market area, changes in accounting and tax principles, estimates made on income taxes, competition with other entities that offer financial services, cybersecurity threats, and such other factors as discussed in Part I Item 1A - "Risk Factors" and Part II Item 7 - "Management's Discussion and Analysis of Financial Condition and Results of Operations" in the Company's 20192020 Annual Report on Form 10-K and in Part II Item 1A of this Quarterly Report on Form 10-Q. Except as set forth in Part II, Item 1A, during the quarter ended September 30, 2020,March 31, 2021, there were no material changes to the Risk Factors disclosed in the Company's 20192020 Annual Report on Form 10-K.

Critical Accounting Policies
The Company has identified several policies as being critical because they require management to make particularly difficult, subjective and/or complex judgments about matters that are inherently uncertain and because of the likelihood that materially different amounts would be reported under different conditions or using different assumptions. These policies relate to the allowance for credit losses and the valuation of certain investment securities. A discussion of these policies can be found in the sections captioned "Critical Accounting Policies" and "Allowance for Credit Losses on Loans and Liability for Unfunded Lending Commitments" in Management's Discussion and Analysis of Financial Condition and Results of Operations included in the Company's 20192020 Annual Report on Form 10-K. On January 1, 2020, the Company adopted ASU 2016-13 (CECL), and as a result, the Company's "Allowance for Loan Losses" accounting policy has been replaced by its "Allowance for Credit Losses" policy. There have been no other changes in the Company's application of critical accounting policies since December 31, 2019.2020.

Allowance for Credit Losses
The Company’s Allowance for Credit Losses policy covers the collectability of its loan portfolio, the exposure of its unfunded lending commitments, and the potential for credit losses in its available for sale investment portfolio.The Company performs periodic and systematic detailed reviews of its loan portfolio and unfunded lending commitments to assess overall collectability. The level of the allowance for credit losses on loans and unfunded lending commitments reflects the Company's estimate of the losses inherent in the loan portfolio and unfunded lending commitments at any point in time. While these estimates are based on substantive methods for determining allowance requirements, actual outcomes may differ significantly from estimated results, especially when determining allowances for business, construction and business real estate loans, as well as for their related unfunded lending commitments. These loans and commitments are normally larger and more complex, and their collection rates are harder to predict. Personal banking loans, including personal real estate, credit card and consumer loans, are individually smaller and perform in a more homogenous manner, making loss estimates more predictable. Additionally, the allowance for credit losses requires the calculation of expected lifetime credit losses utilizing a forward-looking forecast of macroeconomic conditions, which may differ significantly from actual results. Further discussion of the methodology used in establishing the allowance is provided in the Allowance for Credit Losses on Loans and Liability for Unfunded Lending Commitments section of Item 2 and in Note 1 to the consolidated financial statements.

The level of the allowance for credit losses on available for sale securities reflects the Company’s estimate of the losses inherent in the available for sale debt security portfolio. In order to estimate the allowance for credit losses on available for sale debt securities, the Company performs quarterly reviews of its investment portfolio to identify securities in an unrealized loss position. If the unrealized loss is not expected to be recovered, the Company performs further analyses to determine whether any portion of the unrealized loss indicates that a credit loss exists. Further discussion of the methodology used in establishing the allowance for credit losses on available for sale securities is provided in Note 1 to the consolidated financial statements.

(3) The efficiency ratio is calculated as non-interest expense (excluding intangibles amortization) as a percent of revenue.
(4) The tangible common equity to tangible assets ratio is a measurement which management believes is a useful indicator of capital adequacy and utilization. It provides a meaningful basis for period to period and company to company comparisons, and also assists regulators, investors and analysts in analyzing the financial position of the Company. Tangible common equity and tangible assets are non-GAAP measures and should not be viewed as substitutes for, or superior to, data prepared in accordance with GAAP.

The Company has an established process to determine the amount of the allowance for credit losses on loans and the liability for unfunded lending commitments, which assesses the risks and losses inherentexpected in its portfolios. This process provides an allowance based on estimates of allowances for pools of loans and unfunded lending commitments, as well as a second, smaller component based on certain individually evaluated loans and unfunded lending commitments. The Company's policies and processes for determining the allowance for credit losses on loans and the liability for unfunded lending commitments are discussed in Note 1 to the consolidated financial statements and in the "Allowance for Credit Losses" discussion within Critical Accounting Policies in Item 2 above.7 of the 2020 Annual Report on Form 10-K.

Net loan charge-offs in the thirdfirst quarter of 20202021 amounted to $7.6$10.0 million, compared to $8.4$8.0 million in the prior quarter and $11.5$10.9 million in the thirdfirst quarter of last year. During the thirdfirst quarter of 2020,2021, the Company recorded net charge-offs on commercial loans of $194$17 thousand, compared to net charge-offs of $3.2 million$572 thousand in the prior quarter. The decrease in commercial loan net charge-offs was primarily driven by a $3.0 million$585 thousand decrease in net charge-offs on business loans this quarter, compared to the second quarter of 2020.prior quarter. In addition to the decrease in commercial net loan charge-offs, net charge-offs on consumer loans decreased $1.2 million$397 thousand in the thirdfirst quarter of 20202021 compared to the prior quarter. These decreases were partially offset by an increase of $3.7$3.0 million in net charge-offs on consumer credit card loans in the thirdfirst quarter of 20202021 compared to the prior quarter. The increase in consumer credit card net charge-offs compared to prior quarter was a result of a COVID-related relief program offered during 2020 that caused the past due and charge-off process on some loans to not advance for several months. As the short-term relief expired, those loans progressed into past due stages during the fourth quarter of 2020 and were ultimately charged-off during the first quarter of 2021. Compared to the same period last year, net loan charge-offs in the thirdfirst quarter of 20202021 decreased $3.9 million.$906 thousand. The decrease in net charge-offs during the thirdfirst quarter of 20202021 compared to the same quarter last year was driven by lower net charge-offs on consumer, loansoverdraft, and consumer credit card loans of $1.9 million$948 thousand, $273 thousand, and $1.3 million, respectively. These decreases were primarily the result$176 thousand, respectively, partly offset by lower net recoveries on business loans of various COVID-19 relief programs that allowed customers to defer loan payments without advancing in past due or charge-off status.$369 thousand.

For the three months ended September 30, 2020,March 31, 2021, annualized net charge-offs on average consumer credit card loans totaled 4.47%5.98%, compared to 2.17%3.72% in the previous quarter and 4.45%5.06% in the same period last year. Consumer loan annualized net charge-offs in the current quarter amounted to .04%.16%, compared to .28%.23% in the prior quarter and .43%.35% in the same period last year. In the thirdfirst quarter of 2020,2021, total annualized net loan charge-offs were .18%.25%, compared to .21%.19% in the previous quarter, and .32%.30% in the same period last year.

As noted in Note 1, the Company adopted ASU 2016-13, known as CECL, on January 1, 2020. Upon adoption, the allowance for credit losses on loans was reduced $21.0 million and the liability for unfunded lending commitments increased $16.1 million. The decrease in the allowance for credit losses on loans was significantly influenced by the forecasted economic environment used in the estimation process as required by CECL, which was forecasted to be stable in both the short term and the long term, characterized by low unemployment. As the estimation model for credit losses on lending commitments became governed by CECL, the Company increased the related liability for unfunded lending commitments, mostly related to construction lending as the Company expected to fully fund the commitments under these contracts.

In the current quarter, the provision for credit losses on loans totaled $3.2was a recovery of $10.4 million, which was a $74.3$2.8 million decreaseincrease from the recovery on the provision of $77.5$7.5 million in the prior quarter. The provision for credit losses on loans in the current quarter and decreased $7.8$53.2 million compared to the thirdprovision expense in the first quarter of 2019. 2020. The continued recovery of the provision for credit losses on loans is the result of an improved forecast coupled with lower than projected net charge-offs. The allowance for credit losses significantly increased during the first half of 2020 due to the pandemic-induced recession. The economic forecast utilized in the first half of 2020 captured extreme uncertainty with high unemployment rates, but through various governmental stimulus programs, improvements in the public health crisis due to the development and increasing availability of a COVID-19 vaccine, the projected net charge-offs were not realized and the economic forecast improved, thus allowing the release of the allowance for credit losses during the fourth quarter of 2020 and the first quarter of 2021.

In the current quarter, there was a recovery on the provision for credit losses on unfunded lending commitments totaled $4.1 million, a $1.0 million increase over the provision of $99 thousand, compared to provision expense of $3.0$3.1 million in the prior quarter. The economic forecast usedquarter, and decreased $11.0 million compared to estimatethe first quarter of 2020.

For the quarter ended March 31, 2021, the allowance for credit losses in

September was slightly more optimistic than the forecast utilized in June, which resulted in no additional increase to the allowance for credit losses as of September 30, 2020, and significantly decreased the provision for credit losses this quarter, compared to the prior quarter.

For the quarter ended September 30, 2020, the allowance for credit losses related to commercialon loans decreased $2.1 million and the allowance for credit losses related to personal banking loans decreased $2.3$20.3 million, compared to the allowance for credit losses on loans as of June 30,December 31, 2020. The decrease was primarily due to the slight improvement in the forecastedimproved economic environment compared to the forecast as of June 30, 2020. Due to the pandemic induced recession that started during the first quarter of 2020, the allowance for credit losses increased in the 1st and 2nd quarters of 2020 to capture the expected losses over the life of loans using projections of how the pandemic will impact the economic environment along with other data and assumptions. At September 30, 2020 the projected economic environment was similar to the projected environment at June 30, 2020, just slightly improved. As such, additional reserves were not needed to estimate the expected losses over the life of the loans. Businesses continue to experience disruptions caused by COVID-19 even though state and local governments have partially reopened non-essential businesses throughout the country. Consumer spending has been negatively impacted by the sudden and dramatic increase in unemployment in addition to health risks associated with the virus.forecast. The allowance for credit losses related to business loans decreased $11.0 million due to slight decreases in loan balances coupled with the slight improvement in the economic forecast and was partially offset by an increase in the allowance for credit losses on business real estate loans of $8.1 million, primarily related to certain loans with a potential to be impacted by the pandemic. Additionally, the allowance for credit losses on personal banking loans decreased $2.3 million compared to June 30, 2020, primarily related to the slightly improved forecast projections.

For the nine months ended September 30, 2020, net loan charge-offs totaled $26.8 million, compared to $34.5 million in the same period last year. During the first nine months of 2020, the Company recorded net charge-offs of $3.0 million on commercial loans, compared to net charge-offs of $854 thousand in the first nine months of 2019. Offsetting the increase in commercial loan net charge-offs, consumer credit card loan and consumer loan net charge-offs decreased $6.6 million and $2.4 million, respectively, in the first nine months of 2020, compared to the first nine months of the prior year. The provision for credit losses on loans for the first nine months of 2020 was $123.6 million and exceeded net loan charge-offs for the period by $96.7 million. In the same period last year, provision expense totaled $35.2 million and exceeded net loan charge-offs by $750 thousand.

At September 30, 2020, the allowance for credit losses on loans amounted to $236.4 million, an increase of $96.8 million compared to $139.6 million at January 1, 2020, the adoption date of CECL. Additionally, the liability for unfunded lending commitments increased $18.0 million from $17.2 million at January 1, 2020 to $35.2 million at September 30, 2020. The allowance for credit losses related to commercial loans increased $66.4 million, due to increases in the allowance on business, construction and business real estate loans of $40.7 million, $9.3 million, and $16.4 million, respectively. Compared to January 1, 2020, the allowance for credit losses on consumer credit card loans decreased $14.5 million as a result of the improved economic forecast combined with lower loan balances and lower than expected net charge-offs. Additionally, the allowance for credit losses related to personal real estate, andbanking loans, excluding consumer credit card loans, increased $22.7 million,decreased $3.9 million, and $3.6 million, respectively. These large increases resulted fromwhile the sudden entrance into a sharp recession broughtallowance for credit losses on by an unprecedented pandemic. The economic outlook quickly shifted from a stable economy with low unemployment atcommercial loans decreased $1.9 million. While the beginning offorecast continued to improve, the year to an uncertain economic projection at September 30, 2020, defined by high unemployment, periods of governmental shut down of non-essential businesses, and other business and personal disruptions caused by COVID-19. Givenallowance considers the significant uncertainty of future potential COVID-19 disruptions on both the economic projections of a pandemic induced recession, the estimate uses a short reasonableconsumer and supportable forecasted period. As the length and depth of the current recession becomes more certain in the coming months, key assumptions utilized in the Company's CECL model may be modified. See Note 2 for explanations of the various model assumptions utilized in this estimate. Traditional credit quality indicators, such as net charge-off experience, greater than 90 days delinquent statistics and decreases in the internal risk rating to special mention or substandard ratings, are lagging credit quality indicators and do not yet reflect the expected impacts of this crisis. Changes in these indicators are delayed as the Company offered certain assistance programs to impacted customers as allowed by various regulations and as customers are able to participate in various governmental support programs. See Note 2 for further discussion of the credit quality indicators, and refer to Risk Elements of the Loan Portfolio, Loans with Special Risk Characteristics for further information about the assistance programs offered by the Company to its customers.commercial portfolios.

The allowance for credit losses on loans and the liability for unfunded lending commitments are estimates that require significant judgment including projections of the macro-economic environment. The Company utilizes a third-party macro-economic forecast that continuously changes due to economic conditions and events. These changes in the forecast cause fluctuations in the allowance for credit losses on loans and the liability for unfunded lending commitments. The Company used its best judgment to assess the macro-economic forecast and internal loss data in estimating the allowance for credit losses on

loans and the liability for unfunded lending commitments. These estimates are subject to periodic refinement based on changes in the underlying external and internal data. Events such as the timing of governmental required business lock downs or possible additional waves of infection could prolong and deepen the projected recession. Alternatively, events such as

Risk Elements of Loan Portfolio
The following table presents non-performing assets and loans which are past due 90 days and still accruing interest. Non-performing assets include non-accruing loans and foreclosed real estate. Loans are placed on non-accrual status when management does not expect to collect payments consistent with acceptable and agreed upon terms of repayment. Loans that are 90 days past due as to principal and/or interest payments are generally placed on non-accrual, unless they are both well-secured and in the process of collection, or they are personal banking loans that are exempt under regulatory rules from being classified as non-accrual. During 2020, Section 4013 of the CARES Act was signed into law and provided financial institutions the option to suspend the requirement to categorize modifications related to the COVID-19 pandemic as troubled debt restructurings. The 2021 Consolidated Appropriations Act signed on December 27, 2020 extends this temporary suspension through January 1, 2022. The Company follows the guidance under the CARES Act when determining if a customer's modification is subject to troubled debt restructuring classification.

Based on the amount and type of collateral pledged, the FHLB establishes a collateral value from which the Company may draw advances against the collateral. Also, this collateral is used to enable the FHLB to issue letters of credit in favor of public fund depositors of the Company. The Federal Reserve Bank also establishes a collateral value of assets pledged and permits borrowings from the discount window.

As a result, the two-year deferral period for the Company extends through December 31, 2021. Beginning on January 1, 2022, the Company will be required to phase in 25% of the previously deferred estimated capital impact of CECL, with an additional 25% to be phased in at the beginning of each subsequent year until fully phased in by the first quarter of 2025.

Commitments, Off-Balance Sheet Arrangements and Contingencies
In the normal course of business, various commitments and contingent liabilities arise which are not required to be recorded on the balance sheet. The most significant of these are loan commitments, which at September 30, 2020March 31, 2021 totaled $12.8$13.3 billion (including $4.9 billion in unused, approved credit card lines).

The Other/Elimination category in the preceding table includes the activity of various support and overhead operating units of the Company, in addition to the investment securities portfolio and other items not allocated to the segments. In accordance with the Company’s transfer pricing procedures, the difference between the total provision for credit losses and total net charge-offs/recoveries is not allocated to a business segment and is included in this category. The pre-tax profitability of this category was lowerhigher than in the same period last year by $179.8$61.1 million. This decreaseincrease was partly due to higher non-interest income of $3.8 million, partly offset by lower net interest income of $53.2$23.0 million and a decreasean increase in non-interest income of $17.4 million, partly offset by lower non-interest expense of $9.6$6.0 million.

Impact of Recently Issued Accounting Standards

Financial Instruments ASU 2016-13, "Measurement of Credit Losses on Financial Instruments", known as the current expected credit loss (CECL) model, was issued in June 2016, and has been followed by additional clarifying guidance on specified implementation issues. This new standard is effective for fiscal years beginning after December 15, 2019 and was adopted by the Company on January 1, 2020 using the modified retrospective method.

This new measurement approach requires the calculation of expected lifetime credit losses and is applied to financial assets measured at amortized cost, including loans and held-to-maturity securities as well as certain unfunded lending commitments such as loan commitments. The standard also changes the impairment model of available for sale debt securities.

The allowance for loan losses under the previously required incurred loss model that is reported on the Company's consolidated balance sheet is different under the requirements of the CECL model. At adoption, a cumulative-effect adjustment for the change in the allowance for credit losses increased retained earnings by $3.8 million. The cumulative-effect adjustment to retained earnings, net of taxes, was comprised of the impact to the allowance for credit losses on outstanding loans and the impact to the liability for unfunded lending commitments. There is no implementation impact on held-to-maturity debt securities as the Company does not hold any held-to-maturity debt securities.

The new accounting standard does not require the use of a specific loss estimation method for purposes of determining the allowance for credit losses. The Company selected a methodology that uses historical net charge-off rates, adjusted by the impacts of a reasonable and supportable forecast and the impacts of other qualitative factors to determine the expected credit losses. Key assumptions include the application of historical loss rates, prepayment speeds, forecast results of a reasonable and supportable period, the period to revert to historical loss rates, and qualitative factors. The forecast is determined using projections of certain macroeconomic variables, such as, unemployment rate, prime rate, BBB corporate yield, and house price index. The model design and methodology requires management judgment.

The allowance for credit losses on the commercial portfolio decreased due to the relatively short contractual lives of the commercial loan portfolios coupled with an economic forecast predicting stable macroeconomic factors similar to the current environment at adoption. The allowance for credit losses on the personal banking portfolio increased due to the relatively longer contractual lives of certain portfolios, primarily those collateralized with personal real estate. Because the commercial loan portfolio represented 63% of total loans at December 31, 2019, the change in its allowance for credit losses had a more
70

Table of Contents
significant impact on the total allowance for credit losses, and resulted in a net reduction in the allowance for credit losses. The Company's allowance for loan losses to total loans ratio declined from 1.09% at December 31, 2019, to .95% at adoption. Offsetting the overall reduction in the allowance for credit losses for outstanding loans was an increase in the liability for unfunded lending commitments. The liability increased as the loss estimation was required to be expanded over the contractual commitment period. The adoption also resulted in an immaterial adjustment to retained earnings at January 1, 2020. Further discussion of the accounting impact of the Company's adoption is included in Note 1 to the consolidated financial statements.

Additionally, the Company elected to phase the estimated impact of CECL into regulatory capital in accordance with the interim final rule of the Federal Reserve Bank and other U.S. banking agencies. Further discussion of the impact of this election is discussed in Capital Management within Liquidity and Capital Resources.

Intangible Assets The FASB issued ASU 2017-04, "Simplifying the Test for Goodwill Impairment", in January 2017. Under current guidance, a goodwill impairment loss is measured by comparing the implied fair value of a reporting unit's goodwill with the carrying amount of that goodwill by following procedures that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Under the new amendments, the goodwill impairment test compares the fair value of a reporting unit with its carrying amount and an impairment charge is measured as the amount by which the carrying amount exceeds the reporting unit's fair value. The amendments were effective for impairment tests beginning January 1, 2020 and did not have a significant effect on the Company's consolidated financial statements.

Financial Instruments The FASB issued ASU 2018-13, "Changes to the Disclosure Requirements of Fair Value Measurement", in August 2018. The amendments in the ASU eliminate or modify certain disclosure requirements for fair value measurements in Topic 820, Fair Value Measurement. In addition, the amendments in the ASU also require the addition of new disclosure requirements on fair value measurement, including the disclosure of changes in unrealized gains and losses for the period included in AOCI for recurring Level 3 fair value measurements and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The guidance was effective January 1, 2020 and did not have a significant effect on the Company's consolidated financial statements.

Retirement Benefits The FASB issued ASU 2018-14, "Compensation - Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20)", in August 2018. The amendments in the ASU eliminate disclosures that are no longer considered cost beneficial and clarify specific requirements of disclosures. In addition, the amendments in the ASU also add new disclosures, including the explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. The amendments were effective January 1, 2020 and did not have a significant effect on the Company's consolidated financial statements.

Intangible Assets The FASB issued ASU 2018-15, "Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract", in August 2018. Under current guidance, the accounting for implementation costs of a hosting arrangement that is a service contract is not specifically addressed. Under the new amendments, the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract are aligned with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software or hosting arrangements that include internal-use software license. The guidance was effective January 1, 2020 and did not have a significant effect on the Company's consolidated financial statements.

Income Taxes The FASB issued ASU 2019-12, "Simplifying the Accounting for Income Taxes", in December 2019. The amendments in the ASU eliminate certain exceptions under current guidance for investments, intraperiod allocations, and the methodology for calculating interim income tax. In addition, the amendments also add new guidance to simplify accounting for income taxes. The amendments arewere effective January 1, 2021, but earlyand the Company adopted them on that date. The adoption is permitted. The Company is still assessing the impactdid not have a significant effect on the Company's consolidated financial statements.

Investment Securities The FASB issued ASU 2020-08, "Codification Improvements to Subtopic 310-20, Receivables - Nonrefundable Fees and Other Costs", in October 2020. The amendments in the ASU clarify that for each reporting period an entity should reevaluateevaluate whether a callable debt security is withinthat has multiple call dates may consider estimates of future principal prepayments when applying the scope of paragraph 310-20-35-33.interest method. The guidance iswas effective January 1, 2021, and isthe Company adopted it on that date. The adoption did not expected to have a significant effect on the Company's consolidated financial statements.

Reference Rate Reform The FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting", in March 2020.2020, and has been followed by additional clarifying guidance related to derivatives that are modified as a result of reference rate reform. The new guidance provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if they reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. Further, the guidance applies to derivative instruments that are affected by the discounting transition. The expedients and exceptions provided by the new guidance do not apply to contract modifications made and hedging relationships entered

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest rate risk management focuses on maintaining consistent growth in net interest income within Board-approved policy limits. The Company primarily uses earnings simulation models to analyze net interest income sensitivity to movement in interest rates. The Company performs monthly simulations that model interest rate movements and risk in accordance with changes to its balance sheet composition. For further discussion of the Company’s market risk, see the Interest Rate Sensitivity section of Management’s Discussion and Analysis of Financial Condition and Results of Operations included in the Company’s 20192020 Annual Report on Form 10-K.

The tables below show the effects of gradual shifts in interest rates over a twelve month period on the Company’s net interest income versus the Company's net interest income in a flat rate scenario.  Simulation A presents three rising rate scenarios and in each scenario, rates are assumed to change evenly over 12 months. In these scenarios, the balance sheet remains flat with the exception of deposit balances, which may fluctuate based on changes in rates. For instance, the Company may experience deposit disintermediation if the spread between market rates and bank deposit rates widens as rates rise.

The sensitivity of deposit balances to changes in rates is particularly difficult to estimate in exceptionally low rate environments. Since the future effects of changes in rates on deposit balances cannot be known with certainty, the Company conservatively models alternate scenarios with greater deposit attrition as rates rise. Simulation B illustrates results from these higher attrition scenarios to provide added perspective on potential effects of higher rates. 

The Company utilizes these simulations both for monitoring interest rate risk and for liquidity planning purposes.  While the future effects of rising rates on deposit balances cannot be known, the Company maintains a practice of running multiple rate scenarios to better understand interest rate risk and its effect on the Company’s performance.

Under Simulation A, in the three rising rates pushrate scenarios, interest income up more quicklyrate risk is less asset sensitive than funding costs. This is predominately duethe previous quarter, which primarily resulted from the addition of PPP loans to interest earning deposits with the Federal Reservesimulation in the current quarter. In the previous quarter, PPP loans were not included in the simulation and variable rate loans repricing up with market rates, whilecontributed to higher deposit rates only partially reprice higher. Depositsbalances at the Federal Reserve declined duringReserve. For the quarter ended March 31, 2021, the addition of the PPP loans to the simulation extended the maturity of the portfolio, causing the assets in the simulation to reprice more gradually, which typically resultsresulted in a less sensitive balance sheet, but this was offset by the monetization of off-balance sheet floors, which no longer lose incomesmaller increase in rising rate scenarios.interest income. The Company did not model a 100 basis point falling scenario due to the already low interest rate environment.

In Simulation B, the assumed higher levels of deposit attrition were modeled to capture the results of a shrinking balance sheet.

Projecting deposit activity in a period of historically low interest rates is difficult, and the Company cannot predict how deposits will actually react to shifting rates.  The comparisons above provide insight into potential effects of changes in rates and deposit levels on net interest income.  The Company believes that its approach to interest rate risk has appropriately considered its susceptibility to both rising and falling rates and has adopted strategies which minimize the impact of interest rate risk.

Item 1. LEGAL PROCEEDINGS

The information required by this item is set forth in Part I, Item 1 under Note 17, Legal and Regulatory Proceedings.

Item 1A. RISK FACTORS

The section titled "Risk Factors" in Part I, Item 1A of the Company's 2019 Annual Report on Form 10-K includes a discussion of the many risks and uncertainties the Company faces, any one or more of which could have a material adverse effect on its business, results of operations, financial condition (including capital and liquidity), or prospects or the value of or return on an investment. The information presented below provides an update to, and should be read in conjunction with, the risk factors and other information contained in the Company's 2019 Annual Report on Form 10-K. Except as presented below, there have been no material changes to the risk factors described in the Company's 2019 Annual Report on Form 10-K.

Public health threats or outbreaks of communicable diseases has adversely affected, and is expected to continue to adversely effect on the Company's operations and financial results
The Company may face risks related to public health threats or outbreaks of communicable diseases. A widespread healthcare crisis, such as an outbreak of a communicable disease could adversely affect the global economy and the Company’s financial performance. For example, the ongoing global COVID-19 pandemic has destabilized the financial markets in which the Company operates, and likely will continue to cause significant disruption in the global economies and financial markets, including the Company's local markets. The Company is dependent upon the willingness and ability of its customers to conduct banking and other financial transactions. In reaction to and as preventative measure to attempt to slow the spread of the pandemic, government authorities have in many states and municipalities implemented mandatory closures, shelter-in-place orders, and social distancing protocols, including orders within many of the geographic areas that the Company operates. Although the Company is considered an essential business, access to its branches and office locations have been restricted, for the safety of its employees and customers. Limiting customers' access to the Company's physical business has prevented some customers from transacting with the Company and lower demand for lending and other services offered by the Company, adversely affecting its cash flows, financial condition, results of operations, profitability and asset quality and could continue to do so for an indefinite period of time. This could have a material adverse effect on the Company’s results of operations, financial condition, and liquidity. In particular, the continued spread of COVID-19 and efforts to contain the virus could:
continue to impact customer demand of the Company’s lending and related services, leading to lower revenue;
cause the Company to experience an increase in costs as a result of the Company implementing operational changes to accommodate its newly-remote workforce;
cause delayed payments from customers and uncollectible accounts, defaults, foreclosures, and declining collateral values, resulting in losses to the Company;
result in losses on the Company's investment portfolio, due to volatility in the markets and lower trading volume driven by economic uncertainty;
cause market interest rates to continue to decline, which could adversely affect the Company's net interest income and profitability;
cause the Company's credit losses to grow substantially;
impact availability of qualified personnel; and
cause other unpredictable events.
The situation surrounding COVID-19 remains uncertain and the potential for a material impact on the Company’s results of operations, financial condition, and liquidity increases the longer the virus impacts activity levels in the United States and globally. The ultimate extent of the impact on our business, financial condition, liquidity, results of operations and cash flows will depend on future developments, which are highly uncertain and cannot be predicted. The Company continues to adapt to the changing dynamics of the COVID-19 impacts to the economy, needs of our employees and customers, and authoritative measures mandated by federal, state, and local governments. However, there is no assurance that our business continuity and disaster recovery program can adequately mitigate the risks of such business disruptions and interruptions. New information regarding the severity of the COVID-19 pandemic and ongoing reactions to the pandemic by customers and government authorities will continue to impact access to the Company's business, as well as the economies and markets in which the Company operates. The COVID-19 pandemic may cause prolonged global or national recessionary economic conditions or
77
