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.

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.</span></div><div style="margin-top:6pt;text-indent:54pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Changes in the allowance for credit losses are recorded as a provision for (or reversal of) credit loss expense.

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.</span></div><div style="margin-top:12pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Troubled Debt Restructured Loans</span></div><div style="margin-top:6pt;text-indent:54pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">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. </span></div><div style="margin-top:6pt;text-indent:54pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">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.

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).</span></div><div style="margin-top:12pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Allowance for Credit Losses</span></div><div style="margin-top:6pt;text-indent:54pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">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.</span></div><div style="margin-top:6pt;text-indent:54pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">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. </span></div><div style="margin-top:6pt;text-indent:54pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">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. </span></div><div style="margin-top:6pt;text-indent:54pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">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:</span></div><div style="margin-top:6pt;padding-left:54pt;text-indent:-18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt">Lending policies and procedures, including underwriting standards and collection, charge-off and recovery practices;</span></div><div style="margin-top:6pt;padding-left:54pt;text-indent:-18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt">Nature and volume of the portfolio;</span></div><div style="margin-top:6pt;padding-left:54pt;text-indent:-18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt">Volume and severity of past-due, non-accrual and classified loans;</span></div><div style="margin-top:6pt;padding-left:54pt;text-indent:-18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt">The value of the underlying collateral for loans that are not collateral dependent;</span></div><div style="margin-top:6pt;padding-left:54pt;text-indent:-18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt">Concentrations of credit risk;</span></div><div style="margin-top:6pt;padding-left:54pt;text-indent:-18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt">Model and data limitations; and</span></div><div style="margin-top:6pt;padding-left:54pt;text-indent:-18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt">Other external factors, such as changes in legal, regulatory or competitive environments.</span></div><div style="margin-top:6pt;text-indent:54pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">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.
