The CECL model also applies to certain off-balance sheet credit exposures.</span></div><div style="margin-top:9pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company estimates the ACL on loans based on the underlying assets’ amortized cost basis, which is the amount at which the financing receivable is originated or acquired, adjusted for applicable accretion or amortization of premium, discount, net deferred fees or costs, collection of cash, and charge-offs. In the event that collection of principal becomes uncertain, the Company has policies in place to write-off accrued interest receivable by reversing interest income in a timely manner. Therefore, the Company has made a policy election to exclude accrued interest from the amortized cost basis and therefore excludes it from the measurement of the ACL. For loans under forbearance as a result of Coronavirus Disease 2019 (“COVID-19”), the Company made a policy election to include the accrued interest receivable related to such loans in the amortized cost basis and therefore includes it in the measurement of the ACL. Accrued interest receivable related to loans at December 31, 2021 was $26.2 million, of which $4.4 million related to forbearance loans.</span></div><div style="margin-top:9pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Expected credit losses are reflected in the ACL through a charge to credit loss expense. The Company’s estimate of the ACL reflects credit losses currently expected over the remaining contractual life of the assets. When the Company deems all or a portion of a financial asset to be uncollectible the appropriate amount is written off and the ACL is reduced by the same amount. The Company applies judgment to determine when a financial asset is deemed uncollectible. When available information confirms that specific financial assets, or portions thereof, are uncollectible, these amounts are charged off against the ACL. Subsequent recoveries, if any, are credited to the ACL when received. </span></div><div style="margin-top:9pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company measures the ACL of financial assets on a collective portfolio segment basis when the financial assets share similar risk characteristics. The Company has identified the following portfolio segments of financial assets with similar risk characteristics for measuring expected credit losses: commercial and industrial, commercial real estate - owner occupied, commercial real estate - investor (including commercial real estate - construction and land), residential real estate, consumer (including student loans) and HTM debt securities. The Company further segments the commercial loan portfolios by risk rating, and the residential and consumer loan portfolios by delinquency. The total ACL on loans measured on a collective portfolio segment basis was $48.6 million as of December 31, 2021. The HTM portfolio is segmented by rating category. </span></div><div style="margin-top:9pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company’s methodology to measure the ACL incorporates both quantitative and qualitative information to assess lifetime expected credit losses at the portfolio segment level. The quantitative component includes the calculation of loss rates using an open pool method. Under this method, the Company calculates a loss rate based on historical loan level loss experience for portfolio segments with similar risk characteristics. The historical loss rate is adjusted for select macroeconomic variables that consider both historical trends as well as forecasted trends for a single economic scenario. The adjusted loss rate is calculated for an eight quarter forecast period then reverts to the historical loss rate on a straight-line basis over four quarters. The Company differentiates its loss-rate method for HTM debt securities by looking to publicly available historical default and recovery statistics based on the attributes of issuer type, rating category and time to maturity. The Company measures expected credit losses of these financial assets by applying loss rates to the amortized cost basis of each asset taking into consideration amortization, prepayment and default assumptions. </span></div><div style="margin-top:9pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company considers qualitative adjustments to expected credit loss estimates for information not already captured in the loss estimation process. Qualitative factor adjustments may increase or decrease management’s estimate of expected credit losses. Adjustments will not be made for information that has already been considered and included in the quantitative allowance. Qualitative loss factors are based on management's judgment of company, market, industry or business specific data, changes in loan composition, performance trends, regulatory changes, uncertainty of macroeconomic forecasts, and other asset specific risk characteristics.</span></div><div style="margin-top:9pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Collateral Dependent Financial Assets</span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">For collateral dependent financial assets where the Company has determined that foreclosure of the collateral is probable and where the borrower is experiencing financial difficulty, the ACL is measured based on the difference between the fair value of the collateral and the amortized cost basis of the asset as of the measurement date. Fair value is generally calculated based on the value of the underlying collateral less an appraisal discount and the estimated cost to sell. Due to conditions caused by COVID-19, appraisals ordered in the current environment may not be indicative of the underlying loan collateral value. As such, the Company may require multiple valuation approaches (sales comparison approach, income approach, and/or cost </span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">approach), as applicable. The Company will assess the individual facts and circumstances of COVID-19-related loan downgrades and, if a new appraisal is not necessary, an additional discount may be applied to an existing appraisal. </span></div><div style="margin-top:9pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Troubled Debt Restructured (“TDR”) Loans</span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">A loan that has been modified or renewed is considered a TDR when two conditions are met: (1) the borrower is experiencing financial difficulty and (2) concessions are made for the borrower's benefit that would not otherwise be considered for a borrower or transaction with similar credit risk characteristics. So long as they share similar risk characteristics, TDRs may be collectively evaluated and included in the Company’s existing portfolio segments to measure the ACL, unless the TDR is collateral dependent. Loans modified in accordance with the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act are not considered TDRs.</span></div><div style="margin-top:9pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Loan Commitments and Allowance for Loan Credit Losses on Off-Balance Sheet Credit Exposures</span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Financial assets include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs.

Such financial instruments are recorded when they are funded.</span></div><div style="margin-top:9pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company records an allowance for loan credit losses on off-balance sheet credit exposures through a charge to loan credit loss expense for off-balance sheet credit exposures.

Certain acquired loans are grouped together according to similar risk characteristics and are aggregated when applying various valuation techniques. These cash flow evaluations are subjective as they require material estimates, all of which may be susceptible to significant change.</span></div><div style="margin-top:9pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Beginning on January 1, 2020, loans acquired in a business combination that have experienced more-than-insignificant deterioration in credit quality since origination are considered purchased with credit deterioration (“PCD”) loans. The Company evaluated acquired loans for deterioration in credit quality based on any of, but not limited to, the following: (1) non-accrual status; (2) troubled debt restructured designation; (3) risk ratings of special mention, substandard or doubtful; (4) watchlist credits; and (5) delinquency status, including loans that were current on acquisition date, but had been previously delinquent. At the acquisition date, an estimate of expected credit losses was made for groups of PCD loans with similar risk characteristics and individual PCD loans without similar risk characteristics. This initial allowance for credit losses is allocated to individual PCD loans and added to the purchase price or acquisition date fair values to establish the initial amortized cost basis of the PCD loans. As the initial allowance for credit losses is added to the purchase price, there is no credit loss expense recognized upon acquisition of a PCD loan. Any difference between the unpaid principal balance of PCD loans and the amortized cost basis is considered to relate to noncredit factors and results in a discount or premium. Discounts and premiums are recognized through interest income on a level-yield method over the life of the loans.</span></div><div style="margin-top:9pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">For acquired loans not deemed PCD at acquisition, the differences between the initial fair value and the unpaid principal balance are recognized as interest income on a level-yield basis over the lives of the related loans.

The adequacy of the allowance for loan losses was based on management’s evaluation of the Bank’s past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, current economic and regulatory conditions, as well as organizational changes. The allowance for loan losses was maintained at an amount management considered sufficient to provide for probable losses.</span></div>
