The measurement of expected credit losses under CECL is applicable to financial assets measured at amortized cost, including loans, HTM securities and purchased financial assets, held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. It also applies to OBS credit exposures, such as loan commitments, standby letters of credit, financial guarantees and other similar instruments. Financial institutions and other organizations will now use forecasted information to better inform their credit loss estimates. Many of the loss estimation techniques applied previously are still permitted, although the inputs to those techniques changed to reflect the full amount of expected credit losses. </span></div><div style="padding-left:36pt;text-align:justify"><span><br/></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%">The Corporation maintains an ACL at a level determined to be adequate to absorb expected credit losses associated with the Corporation’s financial instruments over the life of those instruments as of the balance sheet date. As part of its process of adopting CECL, management implemented a third-party software solution and determined appropriate loan segments, methodologies, model assumptions and qualitative components. The Corporation’s systematic ACL methodology is based on the following portfolio segments: Commercial and Industrial, Commercial Real Estate, Real Estate Construction, Residential Mortgage, Home Equity Lines of Credit and Consumer. The loan portfolio is segmented by loan types that have similar risk characteristics and types of collateral and that behave similarly during economic cycles. The calculation includes both a quantitative and qualitative component which incorporates the forecasting of certain economic variables. The Bank engaged a third-party to assist in developing the CECL model and to assist with evaluation of data and methodologies related to this standard. The Bank’s CECL Committee, which includes members from Credit Administration, Accounting/Finance, Risk Management and Internal Audit, has oversight by the Chief Executive Officer, Chief Financial Officer, and Chief Credit Officer. The Bank’s implementation plan also included the assessment and documentation of appropriate processes, policies and internal controls. Management had a third-party independent consultant review and validate the CECL model.</span></div><div style="text-align:justify"><span><br/></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%">The ultimate impact of adopting Topic 326, and at each subsequent reporting period, is highly dependent on credit quality, macroeconomic forecasts and conditions, composition of the loans and securities portfolio, along with other management judgments. The Corporation adopted Topic 326 using the modified retrospective method. Results for reporting periods beginning after January 1, 2023 are presented under Topic 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP.</span></div><div style="text-align:justify"><span><br/></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%">The segmentation in the CECL model is different from the segmentation in the incurred loss model, however there was minimal impact on the presentation of the financial statement disclosures.

The Corporation elected to use Discounted Cash Flow and chose unemployment rate as the driving factor of their economic forecasts. In regards to unemployment rates, the Corporation elected to forecast economic factors over the period of the next four quarters. The Corporation chose not to extend beyond four quarters given the inherent risks associated with forecasting. The Corporation utilizes relevant third-party forecasts as a basis and support for its own forecast. These forecasts are assumed to revert to the long-term average and utilized in the model to estimate the PD and LGD through regression. The Corporation elected a reversion period of four quarters. The Corporation deemed four quarters to be a reasonable time period to ensure it did not include irrelevant information, but also not too short to introduce unnecessary volatility. Model assumptions include, but are not limited to the discount rate, prepayment speeds, funding rates, PD, LGD and curtailments. The product of the PD and the LGD is the estimated loss rate, which varies over time. The estimated loss rate is applied within the appropriate periods in the cash flow model to determine the net present value. Net present value is also impacted by assumptions related to the duration between default and recovery. The reserve is based on the difference between the summation of the principal balances taking amortized costs into consideration and the summation of the net present values.</span></div><div style="margin-bottom:8pt;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:112%">Qualitative Analysis.</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:112%"> Based on management’s review and analysis of internal, external and model risks, management may adjust the model output.

For such loans that were also classified as impaired, an ACL was established when the discounted cash flows (or collateral value or observable market price) of the impaired loan was lower than the carrying value of that loan. The general component covered pools of loans by loan class including commercial loans not considered impaired, as well as smaller balance homogeneous loans, such as residential real estate, home equity, and other consumer loans. These pools of loans were evaluated for loss exposure based upon historical loss rates for each of these categories of loans, adjusted for qualitative risk factors.

Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and/or interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan by loan basis for commercial and commercial construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent.</span></div><div style="margin-bottom:8pt;margin-top:8pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">A specific allocation within the ACL is established for an impaired loan if its carrying value exceeds its estimated fair value.

In addition, the Corporation orders third-party valuations on all impaired real estate collateralized loans within 30 days of the loan being classified as impaired. Until the valuations are completed, the Corporation utilizes the most recent independent third-party real estate valuation to estimate the need for a specific allocation to be assigned to the loan. These existing valuations are discounted downward to account for such things as the age of the existing collateral valuation, change in the condition of the real estate, change in local market and economic conditions, and other specific factors involving the collateral. Once the updated valuation is completed, the collateral value is updated accordingly.</span></div><div style="margin-bottom:8pt;margin-top:8pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">For commercial and industrial loans secured by non-real estate collateral, such as accounts receivable, inventory and equipment, estimated fair values are determined based on the borrower’s financial statements, inventory reports, accounts receivable aging reports, equipment appraisals, or invoices.
