The level of the allowance is determined under the CECL methodology and includes management's evaluation of historical default and loss experience, current and projected economic conditions, asset quality trends, known and inherent risks in the portfolio, adverse situations that may affect the borrowers' ability to repay a loan (including the timing of future payments), the estimated value of any underlying collateral, composition of the loan portfolio, and other pertinent factors. </span></div><div style="margin-top:10pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Credit losses are estimated on the amortized cost basis of loans, which includes the principal balance outstanding, purchase discounts and premiums, and deferred loan fees and costs. Accrued interest receivable is presented separately on the consolidated balance sheets and excluded from the estimate of credit losses. Loans are charged off when the Company determines that such financial assets are deemed uncollectible. The ACL is increased through provision for loan losses and decreased by charge-offs, net of recoveries of amounts previously charged-off. </span></div><div style="margin-top:10pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The ACL is measured on a collective basis for pools of loans with similar risk characteristics. The Discounted Cash Flow (“DCF”) method is utilized for substantially all pools, with discounted cash flows computed for each loan in a pool based on its individual characteristics (e.g. maturity date, payment amount, interest rate, etc.), and the results are aggregated at the pool level. A probability of default and loss given default, as adjusted for recoveries, are applied to the discounted cash flows for each pool, while considering prepayment and principal curtailment assumptions driven by each loan's collateral type. When the DCF method is used to determine the ACL, management adjusts the effective interest rate used to discount expected cash flows to incorporate expected prepayments. When management determines that foreclosure is probable or when the borrower is experiencing financial difficulty at the reporting date and repayment is expected to be provided substantially through the operation or sale of the collateral, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. </span></div><div style="margin-top:10pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company has identified the following primary pools for measuring expected credit losses.

These loans are generally secured by equipment, inventory, and accounts receivable of the borrower and repayment is primarily dependent on business cash flows. </span></div><div style="padding-left:36pt;text-indent:-18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%;padding-left:14.5pt">Consumer and other loans</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"> - Consumer and other loans include all loans issued to individuals not included in the consumer real estate mortgage classification, including automobile loans, consumer credit cards and loans to finance education, among others. Many consumer loans are unsecured and repayment is primarily dependent on the personal cash flow of the borrower which may be impacted by changes in economic conditions and unemployment</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">.</span></div><div style="margin-top:10pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In determining the proper level of default rates and loss given default, management has determined that the loss experience of the Company provides the best basis for its assessment of expected credit losses. It therefore utilizes its own historical credit loss experience by each loan segment over an economic cycle, while excluding loss experience from certain acquired institutions (i.e., failed banks). Management considers forward-looking information in estimating expected credit losses. For substantially all segments of collectively evaluated loans, the Company incorporates two or more macroeconomic drivers using a statistical regression modeling methodology. The Company subscribes to a third-party service which provides a quarterly macroeconomic baseline forecast and alternative scenarios for the United States economy. The baseline forecast, which incorporates an equal probability of the United States economy performing better or worse than the projection, along with the alternative scenarios, are evaluated by management to determine the best estimate within the range of expected credit losses. </span></div><div style="margin-top:10pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Management has also evaluated the appropriateness of the reasonable and supportable forecast scenarios utilized for each period and has made adjustments as needed. For the contractual term that extends beyond the reasonable and supportable forecast period, the Company reverts to the long-term mean of historical factors over 12 quarters using a straight-line approach. The Company generally utilizes a four-quarter forecast and a 12-quarter reversion period to the long-term average, which is then held static for the remainder of the forecast period.</span></div><div style="margin-top:10pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Included in its systematic methodology to determine its ACL on loans, management considers the need to qualitatively adjust expected credit losses for information not already captured in the loss estimation process. These qualitative adjustments either increase or decrease the quantitative model estimation (i.e., formulaic model results). Each period the Company considers qualitative factors that are relevant within the qualitative framework that includes the following: 1) changes in lending policies, procedures, and strategies, 2) changes in the nature and volume of the portfolio, 3) staff experience, 4) changes in volume and trends in classified loans, delinquencies, and nonaccrual loans, 5) concentration risk, 6) trends in underlying collateral value, 7) external factors, including competition and legal and regulatory factors, 8) changes in the quality of the Company's loan review system, and 9) economic conditions not already captured.</span></div><div style="margin-top:10pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Allowance for Credit Losses - Off-Balance Sheet Credit Exposure</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"> - The Company estimates expected credit losses on commitments to extend credit over the contractual period in which the Company is exposed to credit risk on the underlying commitments, unless the obligation is unconditionally cancellable by the Company. The allowance for off-balance sheet credit exposures, which is reflected within "Other Liabilities," is adjusted for as an increase or decrease to the provision for credit losses for unfunded commitments. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded </span></div>over its estimated life. The allowance is calculated using the same aggregate reserve rates calculated for the funded portion of loans at the portfolio level applied to the amount of commitments expected to fund.
