Summary of Significant Accounting Policies (Policies)	3 Months Ended
Mar. 31, 2022
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Company’s consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”) as set forth by the Financial Accounting Standards Board (“FASB”) and its Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) as well as the rules and interpretive releases of the Securities and Exchange Commission (“SEC”) under the authority of federal securities laws. The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries and entities in which it holds a controlling financial interest through being the primary beneficiary or through holding a majority of the voting interest. All intercompany accounts and transactions have been eliminated in consolidation. Certain previously reported amounts have been reclassified to conform to the current period’s presentation. The accompanying consolidated balance sheet as of March 31, 2022, the consolidated statements of income and comprehensive income and of changes in equity for the three months ended March 31, 2022 and 2021 and statement of cash flows for the three months ended March 31, 2022 and 2021 are unaudited. The consolidated balance sheet as of December 31, 2021 was derived from the audited consolidated financial statements as of that date. The interim consolidated financial statements and the accompanying notes should be read in conjunction with the annual consolidated financial statements and the accompanying notes contained within the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021 (“2021 Form 10-K”), as filed with the SEC. In the opinion of management, the Company’s consolidated financial statements reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the results of operations for the periods presented. The results for the three months ended March 31, 2022 are not necessarily indicative of results to be expected for the year ending December 31, 2022, any other interim periods, or any future year or period.
Use of Estimates	Use of EstimatesIn preparing the Consolidated Financial Statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheets and income and expenses for the periods reported. Actual results could differ from those estimates based on changing conditions, including economic conditions and future events. Material estimates that are particularly susceptible to change relate to the determination of the allowance for credit losses, valuation and fair value measurements, the liabilities for benefit obligations (particularly pensions), the provision for income taxes and impairment of goodwill and other intangibles.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Relevant standards that were recently issued but not yet adopted as of March 31, 2022: In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”). This update modifies how an acquiring entity measures contract assets and contract liabilities of an acquiree in a business combination in accordance with Topic 606. The amendments in this update require the acquiring entity in a business combination to account for revenue contracts as if they had originated the contract and assess how the acquiree accounted for the contract under Topic 606. ASU 2021-08 improves comparability of recognition and measurement of revenue contracts with customers both before and after a business combination. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2022. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2023. The amendments in this update should be applied prospectively to business combinations occurring on or after the effective date of the amendments with early adoption permitted. The Company expects the adoption of this standard will not have a material impact on its consolidated financial statements. In March 2022, the FASB issued ASU 2022-02, Financial Instruments–Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures (“ASU 2022-02”). The amendments in this update eliminate the accounting guidance on troubled debt restructurings (“TDRs”) for creditors in ASC 310-40 and amends the guidance on vintage disclosures, referenced in ASC 326-20-50, to require disclosure of current-period gross write-offs by year of origination. This update supersedes the existing account guidance for TDRs in ASC 310-40 in its entirety and requires entities to evaluate all receivable modifications under existing accounting guidance in ASC 310-20 to determine whether a modification made to a borrower results in a new loan or a continuation of an existing loan. In addition to the elimination of TDR accounting guidance, entities that adopt this update no longer consider renewals, modification and extensions that result from reasonably expected TDRs in their calculation of the allowance for credit losses. Further, if an entity employs a discounted cash flow method to calculate the allowance for credit losses, it will be required to use a post-modification-derived effective interest rate as part of its calculation. The update also requires new disclosures for receivables for which there has been a modification in their contractual cash flows resulting from borrowers experiencing financial difficulties. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Entities may elect to apply the updated guidance on TDR recognition and measurement by using a modified retrospective transition method. The amendments on TDR disclosures and vintage disclosures should be adopted prospectively. The Company expects the adoption of this standard will not have a material impact on its consolidated financial statements. Relevant standards that were adopted during the three months ended March 31, 2022: In June 2016, the FASB issued ASU 2016-13, Financial Instruments–Credit Losses on Financial Instruments and relevant amendments (Topic 326) (“ASU 2016-13”). This update was created to replace the then-current GAAP method of calculating credit losses. Specifically, the standard replaces the existing incurred loss impairment guidance by requiring immediate recognition of expected credit losses. For financial assets carried at amortized cost that are held at the reporting date (including trade and other receivables, loans and commitments, held-to-maturity debt securities and other financial assets), credit losses are measured based on historical experience, current conditions and reasonable supportable forecasts. The standard also amends existing impairment guidance for available for sale securities, in which credit losses will be recorded as an allowance versus a write-down of the amortized cost basis of the security. It also allows for a reversal of impairment loss when the credit of the issuer improves. The guidance requires a cumulative effect of the initial application to be recognized in retained earnings at the date of initial application. In November 2018, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments – Credit Losses (“ASU 2018-19”). The amendments in ASU 2018-19 were intended to clarify that receivables arising from operating leases are not within the scope of Subtopic 326-20. Instead, impairment of receivables arising from operating leases should be accounted for in accordance with Topic 842, Leases. In November 2019, the FASB issued ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments – Credit Losses. This update requires entities to include expected recoveries of the amortized cost basis previously written off or expected to be written off in the valuation account for purchased financial assets with credit deterioration. In addition, the amendments in this update clarify and improve various aspects of the guidance for ASU 2016-13. On January 1, 2022, the Company adopted ASUs 2016-13, 2018-19 and 2019-11 (codified in ASC 326, “Financial Instruments-Credit Losses”), which replaced the incurred loss methodology (codified in ASC 450, “Contingencies,” ASC 310, “Receivables” and ASC 320, “Debt Securities”) with an expected loss methodology that is referred to as current expected credit losses methodology (“CECL methodology”). The Company adopted ASU 2016-13 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures by means of a cumulative-effect adjustment to the opening retained earnings balance on the Company’s consolidated balance sheet as of the Company’s date of adoption of January 1, 2022. Accordingly, results for reporting periods beginning after December 31, 2021 are presented under ASU 2016-13, while prior period amounts continue to be reported in accordance with previously applicable GAAP. The Company recorded a net decrease to retained earnings of $20.1 million, net of deferred taxes of $7.9 million, as of January 1, 2022, for the cumulative effect of adopting ASU 2016-13. The Company adopted ASU 2016-13 using the prospective transition approach for purchased credit-deteriorated (“PCD”) financial assets that were previously classified as purchased credit-impaired (“PCI”) financial assets and accounted for under ASC 310-30. In accordance with ASU 2016-13, the Company did not reassess whether its assets previously classified as PCI assets met the criteria of PCD assets as of the date of adoption. Rather, loans previously determined to be PCI loans are considered to be PCD loans as of January 1, 2022. On January 1, 2022, the amortized cost basis of the PCD assets was adjusted to reflect the addition of the allowance for loan losses on PCD loans. The remaining noncredit discount will be accreted into the Company’s interest income at the then-effective interest rate as of January 1, 2022. The amount of the adjustment for PCD assets was not material to the Company. In March 2020, the FASB issued ASU 2020-4, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). This update addresses optional expedients and exceptions for applying GAAP to certain contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The new guidance applies only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. For public and nonpublic entities, the guidance is effective as of March 12, 2020 through December 31, 2022 and does not apply to contract modifications made after December 31, 2022. The Company performed a review its contracts and existing processes to assess the risks and potential impact of the transition away from LIBOR and noted no material impact to the Company’s consolidated financial statements as of March 31, 2022.
Allowance for Credit Losses	Allowance for Credit Losses - Available for Sale Securities ASU 2016-13 made targeted changes to ASC 320 to eliminate the concept of “other than temporary” from the impairment loss estimation model for available for sale (“AFS”) securities. A summary of the changes made by the Company to the existing impairment model (previously referred to as the “OTTI” impairment model) as a result of adoption of ASU 2016-13 is as follows: •The use of an allowance approach, rather than a permanent write-down of a security’s cost basis upon determination of an impairment loss. •The amount of the allowance is limited to the amount at which the security’s fair value is less than its amortized cost basis. •The Company may not consider the length of time a security’s fair value has been less than amortized cost. •The Company may not consider recoveries in fair value after the balance sheet date when assessing whether a credit loss exists. The Company’s AFS securities are carried at fair value. For AFS securities in an unrealized loss position, management will first evaluate whether there is intent to sell a security, or if it is more likely than not that the Company will be required to sell a security prior to anticipated recovery of its amortized cost basis. If either of these criteria are met, the Company will record a write-down of the security’s amortized cost basis to fair value through income. For those AFS securities which do not meet the intent or requirement to sell criteria, management will evaluate whether the decline in fair value is a result of credit related matters or other factors. In performing this assessment, management considers the creditworthiness of the issuer including whether the security is guaranteed by the U.S. federal government or other government agency, the extent to which fair value is less than amortized cost, and changes in credit rating during the period, among other factors. If this assessment indicates the existence of credit losses, the security will be written down to fair value, as determined by a discounted cash flow analysis. To the extent the estimated cash flows do not support the amortized cost, the deficiency is considered to be due to credit loss and is recognized in earnings. Changes in the allowance for credit losses are recorded as a provision for (or reversal of) credit loss expense. Losses are charged against the allowance when the security is determined to be uncollectible, or when either of the aforementioned criteria surrounding intent or requirement to sell have been met. On January 1, 2022, the date on which the Company adopted ASU 2016-13, no allowance for credit losses was recorded for AFS securities. Refer to Note 3, “Securities” for additional information regarding the measurement of impairment losses on AFS securities. Allowance for Credit Losses - Held to Maturity Securities The Company measures expected credit losses on held to maturity (“HTM”) securities on a collective basis by major security type which, as of March 31, 2022, includes government-sponsored residential and commercial mortgage-backed securities. Securities in the Company’s held to maturity portfolio are guaranteed by either the U.S. federal government or other government sponsored agencies with a long history of no credit losses. As a result, management has determined that these securities have a zero loss expectation and therefore does not estimate an allowance for credit losses on these securities. The Company held no securities classified as held to maturity at December 31, 2021. Refer to Note 3, “Securities” for additional information regarding the measurement of credit losses on HTM securities. Allowance for Loan Losses - Loans Held for Investment Loans Individually Assessed for Impairment ASU 2016-13 indicates that a loan should be measured for impairment individually if that loan shares no similar risk characteristics with other loans. For the Company, loans which have been identified as those to be individually assessed for impairment under CECL include loans that do not share similar risk characteristics with other loans in the corresponding reserve segment. Characteristics of loans meeting this definition may include, but is not limited to: •Loans previously restructured and determined to be TDR loans; •Loans on non-accrual status; and •Loans with a risk rating of 12 under the Company’s risk rating scale, substandard (well-defined weakness) or worse. Collateral-Dependent Loans Management considers a loan to be collateral-dependent when foreclosure of the underlying collateral is probable. In addition, in accordance with ASU 2016-13, the Company elected to apply the collateral-dependent practical expedient whereby the Company measures expected credit losses using the fair value of the collateral, less any estimated costs to sell, when foreclosure is not probable but repayment of the loan is expected to be provided substantially through the operation or sale of the collateral, and the borrower is experiencing financial difficulty. Troubled Debt Restructured Loans In cases where a borrower experiences financial difficulties and the Company makes certain concessionary modifications to contractual terms, the loan is classified as a TDR. Modifications may include adjustments to interest rates, extensions of maturity, consumer loans where the borrower’s obligations have been effectively discharged through Chapter 7 bankruptcy and the borrower has not reaffirmed the debt to the Company, and other actions intended to minimize economic loss and avoid foreclosure or repossession of collateral. Prior to the Company’s adoption of ASU 2016-13, all TDR loans were subject to a specific review for impairment loss each period beginning in the period in which the modification was executed. Subsequent to the adoption of ASU 2016-13, management identifies loans as TDR loans when it has a reasonable expectation that it will execute a TDR modification with a borrower. In addition, subsequent to adoption of ASU 2016-13, management estimates expected credit losses on a collective basis if a group of TDR loans share similar risk characteristics. If a TDR loan’s risk characteristics are not similar to those of any of the Company’s other TDR loans, expected credit losses on the TDR loan are measured individually. The impairment analysis discounts the present value of the anticipated cash flows by the loan’s contractual rate of interest in effect prior to the loan’s modification or the fair value of collateral if the loan is collateral dependent. The amount of credit loss, if any, is recorded as a specific loss allocation to each individual loan or as a loss allocation to the pool of loans, for those loans for which credit loss is measured on a collective basis, in the allowance for credit losses. Any commercial (commercial and industrial, commercial real estate, commercial construction, and business banking loans) or residential loan that has been classified as a TDR and which subsequently defaults is reviewed to determine if the loan should be deemed collateral-dependent. In such an instance, any shortfall between the value of the collateral and the book value of the loan is determined by measuring the recorded investment in the loan against the fair value of the collateral less costs to sell. The Company’s policy is to retain any restructured loan, which is on non-accrual status prior to being modified, on non-accrual status for approximately six months subsequent to being modified before the Company considers its return to accrual status. If the restructured loan is on accrual status prior to being modified, the Company reviews it to determine if the modified loan should remain on accrual status. Purchased Credit-Deteriorated Loans As described above, the Company applied the prospective transition approach with respect to PCD assets upon adoption of ASU 2016-13. Under this approach, loans previously determined to be PCI loans are considered to be PCD loans as of January 1, 2022. PCD loans are acquired individual loans (or acquired groups of loans with similar risk characteristics) that, as of the date of acquisition, have experienced a more-than-insignificant deterioration in credit quality since origination, as determined by the Company’s assessment. A PCD loan is recorded at its purchase price plus the allowance for loan losses expected at the time of acquisition, or “gross up” of the amortized cost basis, if any. Changes in the current estimate of the allowance for loan losses subsequent to acquisition from the estimated allowance previously recorded are recognized in the income statement as provision for credit losses or reversal of provision for credit losses in subsequent periods as they arise. A purchased loan that does not qualify as a PCD asset is accounted for similar to the Company’s method of accounting for originated assets, whereby an allowance for loan losses is recognized with a corresponding increase to the income statement provision for loan losses. Evidence that purchased loans, measured at amortized cost, have more-than-insignificant deterioration in credit quality since origination and, therefore meet the PCD definition, may include past-due status, non-accrual status, risk rating and other standard indicators (i.e., TDRs, charge-offs, bankruptcy). Allowance for Credit Losses Through December 31, 2021, the allowance for loan losses represented management’s best estimate of incurred probable losses in the Company’s loan portfolios based upon management’s assessment of various factors, including the risk characteristics of its loan portfolio, current economic conditions, and trends in loan delinquencies and charge-offs. The Company’s methodology for determining the qualitative component through December 31, 2021 included an assessment of factors affecting the determination of incurred losses in the loan portfolio. Such factors included trends in economic conditions, loan growth, credit underwriting policy exceptions, regulatory and audit findings, and peer comparisons, among others. Upon adoption of ASU 2016-13, effective January 1, 2022, the Company changed its reserve methodology to estimate expected credit losses over the contractual life of loans and leases. The allowance for credit losses, or ACL, is established to provide for the Company’s current estimate of expected lifetime credit losses on loans measured at amortized cost and unfunded lending commitments at the balance sheet date and is established through a provision for credit losses charged to net income. Credit losses are charged directly to the ACL. Subsequent recoveries, if any, are credited to the ACL. Commercial and residential loans are charged-off in the period in which they are deemed uncollectible. Delinquent loans in these product types are subject to ongoing review and analysis to determine if a charge-off in the current period is appropriate. For consumer finance loans, policies and procedures exist that require charge-off consideration upon a certain triggering event depending on the product type. Charge-off triggers include: 120 days delinquent for automobile, home equity, and other consumer loans with the exception of cash reserve loans for which the trigger is 150 days delinquent; death of the borrower; or Chapter 7 bankruptcy. In addition to those events, the charge-off determination includes other loan quality indicators, such as collateral position and adequacy or the presence of other repayment sources. The ACL is evaluated on a regular basis by management. Management uses a methodology to systematically estimate the amount of expected lifetime losses in the portfolio. Expected lifetime losses are estimated on a collective basis for loans sharing similar risk characteristics and are determined using a quantitative model combined with an assessment of certain qualitative factors designed to address forecast risk and model risk inherent in the quantitative model output. For commercial and industrial, commercial real estate, commercial construction and business banking portfolios, the quantitative model uses a loan rating system which is comprised of management’s determination of a financial asset’s probability of default (“PD”), loss given default (“LGD”) and exposure at default (“EAD”), which are derived from historical loss experience and other factors. For residential real estate, consumer home equity and other consumer portfolios, the Company’s quantitative model uses historical loss experience. The quantitative model estimates expected credit losses using loan level data over the estimated life of the exposure, considering the effect of prepayments. Economic forecasts are incorporated into the estimate over a reasonable and supportable forecast period, beyond which is a reversion to the Company’s historical loss average. Management has determined that a reasonable and supportable forecast period of eight quarters, and a straight-line reversion period of four quarters, are appropriate forecast periods for purposes of estimating expected credit losses. As described above, quantitative model results are adjusted for risk factors not considered within the model but which are relevant in estimating the expected credit losses within the loan portfolio. The qualitative risk factors impacting the expected risk of loss within the loan portfolio include the following: •Lending policies and procedures, including underwriting standards and collection, charge-off and recovery practices; •Nature and volume of the portfolio; •Volume and severity of past-due, non-accrual and classified loans; •The value of the underlying collateral for loans that are not collateral dependent; •Concentrations of credit risk; •Model and data limitations; and •Other external factors, such as changes in legal, regulatory or competitive environments. Loans that do not share similar risk characteristics with any pools of assets are subject to individual evaluation and are removed from the collectively assessed pools. For loans that are individually evaluated, the Company uses either a discounted cash flow (“DCF”) approach or, for loans deemed to be collateral dependent or when foreclosure is probable, a fair value of collateral approach. Accrued interest receivable amounts are excluded from balances of loans held at amortized cost and are included within other assets on the consolidated balance sheet. Management has elected not to measure an allowance for credit losses on these amounts as the Company employs a timely write-off policy. Consistent with the Company's policy for non-accrual loans, accrued interest receivable is typically written off when loans reach 90 days past due and are placed on non-accrual status. In the ordinary course of business, the Company enters into commitments to extend credit and standby letters of credit. Such financial instruments are recorded in the financial statements when they become payable. The credit risk associated with these commitments is evaluated in a manner similar to the reserving method for loans receivable previously described. The reserve for unfunded lending commitments is included in other liabilities in the balance sheet. Additionally, various regulatory agencies, as an integral part of the Company’s examination process, periodically assess the appropriateness of the allowance for credit losses and may require the Company to increase its allowance for loan losses or recognize further loan charge-offs, in accordance with GAAP.

Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2022

The Company’s consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”) as set forth by the Financial Accounting Standards Board (“FASB”) and its Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) as well as the rules and interpretive releases of the Securities and Exchange Commission (“SEC”) under the authority of federal securities laws.

The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries and entities in which it holds a controlling financial interest through being the primary beneficiary or through holding a majority of the voting interest. All intercompany accounts and transactions have been eliminated in consolidation.

Certain previously reported amounts have been reclassified to conform to the current period’s presentation.

The accompanying consolidated balance sheet as of March 31, 2022, the consolidated statements of income and comprehensive income and of changes in equity for the three months ended March 31, 2022 and 2021 and statement of cash flows for the three months ended March 31, 2022 and 2021 are unaudited. The consolidated balance sheet as of December 31, 2021 was derived from the audited consolidated financial statements as of that date. The interim consolidated financial statements and the accompanying notes should be read in conjunction with the annual consolidated financial statements and the accompanying notes contained within the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021 (“2021 Form 10-K”), as filed with the SEC. In the opinion of management, the Company’s consolidated financial statements reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the results of operations for the periods presented. The results for the three months ended March 31, 2022 are not necessarily indicative of results to be expected for the year ending December 31, 2022, any other interim periods, or any future year or period.

Use of Estimates

Use of EstimatesIn preparing the Consolidated Financial Statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheets and income and expenses for the periods reported. Actual results could differ from those estimates based on changing conditions, including economic conditions and future events. Material estimates that are particularly susceptible to change relate to the determination of the allowance for credit losses, valuation and fair value measurements, the liabilities for benefit obligations (particularly pensions), the provision for income taxes and impairment of goodwill and other intangibles.

Recent Accounting Pronouncements

Relevant standards that were recently issued but not yet adopted as of March 31, 2022:

In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”). This update modifies how an acquiring entity measures contract assets and contract liabilities of an acquiree in a business combination in accordance with Topic 606. The amendments in this update require the acquiring entity in a business combination to account for revenue contracts as if they had originated the contract and assess how the acquiree accounted for the contract under Topic 606. ASU 2021-08 improves comparability of recognition and measurement of revenue contracts with customers both before and after a business combination. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2022. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2023. The amendments in this update should be applied prospectively to business combinations occurring on or after the effective date of the amendments with early adoption permitted. The Company expects the adoption of this standard will not have a material impact on its consolidated financial statements.

In March 2022, the FASB issued ASU 2022-02, Financial Instruments–Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures (“ASU 2022-02”). The amendments in this update eliminate the accounting guidance on troubled debt restructurings (“TDRs”) for creditors in ASC 310-40 and amends the guidance on vintage disclosures, referenced in ASC 326-20-50, to require disclosure of current-period gross write-offs by year of origination. This update supersedes the existing account guidance for TDRs in ASC 310-40 in its entirety and requires entities to evaluate all receivable modifications under existing accounting guidance in ASC 310-20 to determine whether a modification made to a borrower results in a new loan or a continuation of an existing loan. In addition to the elimination of TDR accounting guidance, entities that adopt this update no longer consider renewals, modification and extensions that result from reasonably expected TDRs in their calculation of the allowance for credit losses. Further, if an entity employs a discounted cash flow method to calculate the allowance for credit losses, it will be required to use a post-modification-derived effective interest rate as part of its calculation. The update also requires new disclosures for receivables for which there has been a modification in their contractual cash flows resulting from borrowers experiencing financial difficulties. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Entities may elect to apply the updated guidance on TDR recognition and measurement by using a modified retrospective transition method. The amendments on TDR disclosures and vintage disclosures should be adopted prospectively. The Company expects the adoption of this standard will not have a material impact on its consolidated financial statements.

Relevant standards that were adopted during the three months ended March 31, 2022:

In June 2016, the FASB issued ASU 2016-13, Financial Instruments–Credit Losses on Financial Instruments and relevant amendments (Topic 326) (“ASU 2016-13”). This update was created to replace the then-current GAAP method of calculating credit losses. Specifically, the standard replaces the existing incurred loss impairment guidance by requiring immediate recognition of expected credit losses. For financial assets carried at amortized cost that are held at the reporting date (including trade and other receivables, loans and commitments, held-to-maturity debt securities and other financial assets), credit losses are measured based on historical experience, current conditions and reasonable supportable forecasts. The standard also amends existing impairment guidance for available for sale securities, in which credit losses will be recorded as an allowance versus a write-down of the amortized cost basis of the security. It also allows for a reversal of impairment loss when the credit of the issuer improves. The guidance requires a cumulative effect of the initial application to be recognized in retained earnings at the date of initial application.

In November 2018, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments – Credit Losses (“ASU 2018-19”). The amendments in ASU 2018-19 were intended to clarify that receivables arising from operating leases are not within the scope of Subtopic 326-20. Instead, impairment of receivables arising from operating leases should be accounted for in accordance with Topic 842, Leases. In November 2019, the FASB issued ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments – Credit Losses. This update requires entities to include expected recoveries of the amortized cost basis previously written off or expected to be written off in the valuation account for purchased financial assets with credit deterioration. In addition, the amendments in this update clarify and improve various aspects of the guidance for ASU 2016-13.

On January 1, 2022, the Company adopted ASUs 2016-13, 2018-19 and 2019-11 (codified in ASC 326, “Financial Instruments-Credit Losses”), which replaced the incurred loss methodology (codified in ASC 450, “Contingencies,” ASC 310, “Receivables” and ASC 320, “Debt Securities”) with an expected loss methodology that is referred to as current expected credit losses methodology (“CECL methodology”). The Company adopted ASU 2016-13 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures by means of a cumulative-effect adjustment to the opening retained earnings balance on the Company’s consolidated balance sheet as of the Company’s date of adoption of January 1, 2022. Accordingly, results for reporting periods beginning after December

31, 2021 are presented under ASU 2016-13, while prior period amounts continue to be reported in accordance with previously applicable GAAP. The Company recorded a net decrease to retained earnings of $20.1 million, net of deferred taxes of $7.9 million, as of January 1, 2022, for the cumulative effect of adopting ASU 2016-13. The Company adopted ASU 2016-13 using the prospective transition approach for purchased credit-deteriorated (“PCD”) financial assets that were previously classified as purchased credit-impaired (“PCI”) financial assets and accounted for under ASC 310-30. In accordance with ASU 2016-13, the Company did not reassess whether its assets previously classified as PCI assets met the criteria of PCD assets as of the date of adoption. Rather, loans previously determined to be PCI loans are considered to be PCD loans as of January 1, 2022. On January 1, 2022, the amortized cost basis of the PCD assets was adjusted to reflect the addition of the allowance for loan losses on PCD loans. The remaining noncredit discount will be accreted into the Company’s interest income at the then-effective interest rate as of January 1, 2022. The amount of the adjustment for PCD assets was not material to the Company.

In March 2020, the FASB issued ASU 2020-4, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). This update addresses optional expedients and exceptions for applying GAAP to certain contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The new guidance applies only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. For public and nonpublic entities, the guidance is effective as of March 12, 2020 through December 31, 2022 and does not apply to contract modifications made after December 31, 2022. The Company performed a review its contracts and existing processes to assess the risks and potential impact of the transition away from LIBOR and noted no material impact to the Company’s consolidated financial statements as of March 31, 2022.

Allowance for Credit Losses

Allowance for Credit Losses - Available for Sale Securities

ASU 2016-13 made targeted changes to ASC 320 to eliminate the concept of “other than temporary” from the impairment loss estimation model for available for sale (“AFS”) securities. A summary of the changes made by the Company to the existing impairment model (previously referred to as the “OTTI” impairment model) as a result of adoption of ASU 2016-13 is as follows:

•The use of an allowance approach, rather than a permanent write-down of a security’s cost basis upon determination of an impairment loss.

•The amount of the allowance is limited to the amount at which the security’s fair value is less than its amortized cost basis.

•The Company may not consider the length of time a security’s fair value has been less than amortized cost.

•The Company may not consider recoveries in fair value after the balance sheet date when assessing whether a credit loss exists.

The Company’s AFS securities are carried at fair value. For AFS securities in an unrealized loss position, management will first evaluate whether there is intent to sell a security, or if it is more likely than not that the Company will be required to sell a security prior to anticipated recovery of its amortized cost basis. If either of these criteria are met, the Company will record a write-down of the security’s amortized cost basis to fair value through income. For those AFS securities which do not meet the intent or requirement to sell criteria, management will evaluate whether the decline in fair value is a result of credit related matters or other factors. In performing this assessment, management considers the creditworthiness of the issuer including whether the security is guaranteed by the U.S. federal government or other government agency, the extent to which fair value is less than amortized cost, and changes in credit rating during the period, among other factors. If this assessment indicates the existence of credit losses, the security will be written down to fair value, as determined by a discounted cash flow analysis. To the extent the estimated cash flows do not support the amortized cost, the deficiency is considered to be due to credit loss and is recognized in earnings.

Changes in the allowance for credit losses are recorded as a provision for (or reversal of) credit loss expense. Losses are charged against the allowance when the security is determined to be uncollectible, or when either of the aforementioned criteria surrounding intent or requirement to sell have been met. On January 1, 2022, the date on which the Company adopted ASU 2016-13, no allowance for credit losses was recorded for AFS securities.

Refer to Note 3, “Securities” for additional information regarding the measurement of impairment losses on AFS securities.

Allowance for Credit Losses - Held to Maturity Securities

The Company measures expected credit losses on held to maturity (“HTM”) securities on a collective basis by major security type which, as of March 31, 2022, includes government-sponsored residential and commercial mortgage-backed securities. Securities in the Company’s held to maturity portfolio are guaranteed by either the U.S. federal government or other government sponsored agencies with a long history of no credit losses. As a result, management has determined that these securities have a zero loss expectation and therefore does not estimate an allowance for credit losses on these securities. The Company held no securities classified as held to maturity at December 31, 2021. Refer to Note 3, “Securities” for additional information regarding the measurement of credit losses on HTM securities.

Allowance for Loan Losses - Loans Held for Investment

Loans Individually Assessed for Impairment

ASU 2016-13 indicates that a loan should be measured for impairment individually if that loan shares no similar risk characteristics with other loans. For the Company, loans which have been identified as those to be individually assessed for impairment under CECL include loans that do not share similar risk characteristics with other loans in the corresponding reserve segment. Characteristics of loans meeting this definition may include, but is not limited to:

•Loans previously restructured and determined to be TDR loans;

•Loans on non-accrual status; and

•Loans with a risk rating of 12 under the Company’s risk rating scale, substandard (well-defined weakness) or worse.

Collateral-Dependent Loans

Management considers a loan to be collateral-dependent when foreclosure of the underlying collateral is probable. In addition, in accordance with ASU 2016-13, the Company elected to apply the collateral-dependent practical expedient whereby the Company measures expected credit losses using the fair value of the collateral, less any estimated costs to sell, when foreclosure is not probable but repayment of the loan is expected to be provided substantially through the operation or sale of the collateral, and the borrower is experiencing financial difficulty.

Troubled Debt Restructured Loans

In cases where a borrower experiences financial difficulties and the Company makes certain concessionary modifications to contractual terms, the loan is classified as a TDR. Modifications may include adjustments to interest rates, extensions of maturity, consumer loans where the borrower’s obligations have been effectively discharged through Chapter 7 bankruptcy and the borrower has not reaffirmed the debt to the Company, and other actions intended to minimize economic loss and avoid foreclosure or repossession of collateral. Prior to the Company’s adoption of ASU 2016-13, all TDR loans were subject to a specific review for impairment loss each period beginning in the period in which the modification was executed. Subsequent to the adoption of ASU 2016-13, management identifies loans as TDR loans when it has a reasonable expectation that it will execute a TDR modification with a borrower. In addition, subsequent to adoption of ASU 2016-13, management estimates expected credit losses on a collective basis if a group of TDR loans share similar risk characteristics. If a TDR loan’s risk characteristics are not similar to those of any of the Company’s other TDR loans, expected credit losses on the TDR loan are measured individually. The impairment analysis discounts the present value of the anticipated cash flows by the loan’s contractual rate of interest in effect prior to the loan’s modification or the fair value of collateral if the loan is collateral dependent. The amount of credit loss, if any, is recorded as a specific loss allocation to each individual loan or as a loss allocation to the pool of loans, for those loans for which credit loss is measured on a collective basis, in the allowance for credit losses. Any commercial (commercial and industrial, commercial real estate, commercial construction, and business banking loans) or residential loan that has been classified as a TDR and which subsequently defaults is reviewed to determine if the loan should be deemed collateral-dependent. In such an instance, any shortfall between the value of the collateral and the book value of the loan is determined by measuring the recorded investment in the loan against the fair value of the collateral less costs to sell.

The Company’s policy is to retain any restructured loan, which is on non-accrual status prior to being modified, on non-accrual status for approximately six months subsequent to being modified before the Company considers its return to accrual status. If the restructured loan is on accrual status prior to being modified, the Company reviews it to determine if the modified loan should remain on accrual status.

Purchased Credit-Deteriorated Loans

As described above, the Company applied the prospective transition approach with respect to PCD assets upon adoption of ASU 2016-13. Under this approach, loans previously determined to be PCI loans are considered to be PCD loans as of January 1, 2022. PCD loans are acquired individual loans (or acquired groups of loans with similar risk characteristics) that, as of the date of acquisition, have experienced a more-than-insignificant deterioration in credit quality since origination, as determined by the Company’s assessment. A PCD loan is recorded at its purchase price plus the allowance for loan losses expected at the time of acquisition, or “gross up” of the amortized cost basis, if any. Changes in the current estimate of the allowance for loan losses subsequent to acquisition from the estimated allowance previously recorded are recognized in the income statement as provision for credit losses or reversal of provision for credit losses in subsequent periods as they arise. A purchased loan that does not qualify as a PCD asset is accounted for similar to the Company’s method of accounting for originated assets, whereby an allowance for loan losses is recognized with a corresponding increase to the income statement provision for loan losses. Evidence that purchased loans, measured at amortized cost, have more-than-insignificant deterioration in credit quality since origination and, therefore meet the PCD definition, may include past-due status, non-accrual status, risk rating and other standard indicators (i.e., TDRs, charge-offs, bankruptcy).

Allowance for Credit Losses

Through December 31, 2021, the allowance for loan losses represented management’s best estimate of incurred probable losses in the Company’s loan portfolios based upon management’s assessment of various factors, including the risk characteristics of its loan portfolio, current economic conditions, and trends in loan delinquencies and charge-offs. The Company’s methodology for determining the qualitative component through December 31, 2021 included an assessment of factors affecting the determination of incurred losses in the loan portfolio. Such factors included trends in economic conditions, loan growth, credit underwriting policy exceptions, regulatory and audit findings, and peer comparisons, among others. Upon adoption of ASU 2016-13, effective January 1, 2022, the Company changed its reserve methodology to estimate expected credit losses over the contractual life of loans and leases.

The allowance for credit losses, or ACL, is established to provide for the Company’s current estimate of expected lifetime credit losses on loans measured at amortized cost and unfunded lending commitments at the balance sheet date and is established through a provision for credit losses charged to net income. Credit losses are charged directly to the ACL. Subsequent recoveries, if any, are credited to the ACL. Commercial and residential loans are charged-off in the period in which they are deemed uncollectible. Delinquent loans in these product types are subject to ongoing review and analysis to determine if a charge-off in the current period is appropriate. For consumer finance loans, policies and procedures exist that require charge-off consideration upon a certain triggering event depending on the product type. Charge-off triggers include: 120 days delinquent for automobile, home equity, and other consumer loans with the exception of cash reserve loans for which the trigger is 150 days delinquent; death of the borrower; or Chapter 7 bankruptcy. In addition to those events, the charge-off determination includes other loan quality indicators, such as collateral position and adequacy or the presence of other repayment sources.

The ACL is evaluated on a regular basis by management. Management uses a methodology to systematically estimate the amount of expected lifetime losses in the portfolio. Expected lifetime losses are estimated on a collective basis for loans sharing similar risk characteristics and are determined using a quantitative model combined with an assessment of certain qualitative factors designed to address forecast risk and model risk inherent in the quantitative model output. For commercial and industrial, commercial real estate, commercial construction and business banking portfolios, the quantitative model uses a loan rating system which is comprised of management’s determination of a financial asset’s probability of default (“PD”), loss given default (“LGD”) and exposure at default (“EAD”), which are derived from historical loss experience and other factors. For residential real estate, consumer home equity and other consumer portfolios, the Company’s quantitative model uses historical loss experience.

The quantitative model estimates expected credit losses using loan level data over the estimated life of the exposure, considering the effect of prepayments. Economic forecasts are incorporated into the estimate over a reasonable and supportable forecast period, beyond which is a reversion to the Company’s historical loss average. Management has determined that a reasonable and supportable forecast period of eight quarters, and a straight-line reversion period of four quarters, are appropriate forecast periods for purposes of estimating expected credit losses. As described above, quantitative model results are adjusted for risk factors not considered within the model but which are relevant in estimating the expected credit losses within the loan portfolio. The qualitative risk factors impacting the expected risk of loss within the loan portfolio include the following:

•Lending policies and procedures, including underwriting standards and collection, charge-off and recovery practices;

•Nature and volume of the portfolio;

•Volume and severity of past-due, non-accrual and classified loans;

•The value of the underlying collateral for loans that are not collateral dependent;

•Concentrations of credit risk;

•Model and data limitations; and

•Other external factors, such as changes in legal, regulatory or competitive environments.

Loans that do not share similar risk characteristics with any pools of assets are subject to individual evaluation and are removed from the collectively assessed pools. For loans that are individually evaluated, the Company uses either a discounted cash flow (“DCF”) approach or, for loans deemed to be collateral dependent or when foreclosure is probable, a fair value of collateral approach.

Accrued interest receivable amounts are excluded from balances of loans held at amortized cost and are included within other assets on the consolidated balance sheet. Management has elected not to measure an allowance for credit losses on these amounts as the Company employs a timely write-off policy. Consistent with the Company's policy for non-accrual loans, accrued interest receivable is typically written off when loans reach 90 days past due and are placed on non-accrual status.

In the ordinary course of business, the Company enters into commitments to extend credit and standby letters of credit. Such financial instruments are recorded in the financial statements when they become payable. The credit risk associated with these commitments is evaluated in a manner similar to the reserving method for loans receivable previously described. The reserve for unfunded lending commitments is included in other liabilities in the balance sheet.

Additionally, various regulatory agencies, as an integral part of the Company’s examination process, periodically assess the appropriateness of the allowance for credit losses and may require the Company to increase its allowance for loan losses or recognize further loan charge-offs, in accordance with GAAP.
