​ ​ ​ Non-accrual loans that have been subject to partial charge-offs totaled $1.2 million at September 30, 2024 and $0.1 million at December 31, 2023. Loans secured by 1-4 family residential real estate properties in the process of foreclosure totaled $1.6 million at September 30, 2024 and $1.8 million at December 31, 2023. As a percentage of the loan portfolio, accruing loans past due 30 days or more was 0.37% at September 30, 2024 compared to 0.24% at December 31, 2023. ​ The Corporation maintains an ACL at a level that management believes will 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. The Corporation develops and documents a systematic ACL methodology based on the following portfolio segments: (i) commercial real estate; (ii) acquisition and development; (iii) commercial and industrial; (iv) residential mortgage; and (v) consumer. The Corporation’s loan portfolio is segmented by homogeneous loan types that behave similarly to economic cycles. The following is a discussion of the key risks by portfolio segment that management assesses in preparing the ACL. Commercial real estate loans are secured by commercial purpose real estate, including both owner occupied properties and properties obtained for investment purposes, such as hotels, strip malls and apartments. Operations of the individual projects as well as global cash flows of the debtors are the primary source of repayment of these loans. The condition of the local economy is an important indicator of risk, but there are more specific risks depending on the collateral type as well as the business. Acquisition and development loans include both commercial and consumer. Commercial loans are made to finance construction of buildings or other structures, as well as to finance the acquisition and development of raw land for various purposes. The risk of these loans is generally confined to the construction period. If there are problems during such period, then the project might not be completed and, as such, might not provide sufficient cash flow on its own to service the debt or have sufficient value in a liquidation to cover the outstanding principal. The condition of the local economy is an important indicator of risk, but there are also more specific risks depending on the type of project and the experience and resources of the developer. Consumer loans are made for the construction of residential homes for which a binding sales contract exists and generally are for a period of time sufficient to complete construction. Residential construction loans to individuals generally provide for the payment of interest only during the construction phase. Credit risk for residential real estate construction loans can arise from construction delays, cost overruns, failure of the contractor to complete the project to specifications and economic conditions that could impact demand for supply of the property being constructed. Commercial and industrial loans are made to operating companies or manufacturers for the purpose of production, operating capacity, accounts receivable, inventory or equipment financing. Cash flow from the operations of the borrower is the primary source of repayment for these loans. The condition of the local economy is an important indicator of risk, but there are also more specific risks depending on the industry of the borrower. Collateral for these types of loans often do not have sufficient value in a distressed or liquidation scenario to satisfy the outstanding debt. These loans are also made to local municipalities for various purposes including refinancing existing obligations, infrastructure up-fit and expansion, or to purchase new equipment. The primary repayment source for local municipalities include the tax base of the municipality, specific revenue streams related to the infrastructure financed, and other business operations of the municipal authority. The health and stability of state and local economies directly impacts each municipality’s tax basis and are important indicators of risk for this segment. The ability of each municipality to increase taxes and fees to offset service requirements give this type of loan a very low risk profile in the continuum of the Corporation’s loan portfolio. Residential mortgage loans are secured by first and junior liens such as home equity lines of credit and 1-4 family residential mortgages. The primary source of repayment for these loans is the income of the borrower. The condition of the local economy, in particular the unemployment rate, is an important indicator of risk for this segment. The state of the local housing market can also have a significant impact on this segment because low demand and/or declining home values can limit the ability of borrowers to sell a property and satisfy debt. Consumer loans are made to individuals and may be either secured by assets other than 1-4 family residences or unsecured. This segment includes automobile loans and unsecured loans and lines of credit. The primary source of repayment for these loans is the income and assets of the borrower. The condition of the local economy, in particular the unemployment rate, is an important indicator of risk for this segment. The value of the collateral, if there is any, is less likely to be a source of repayment due to less certain collateral values. The following table summarizes the primary segments of the ACL at September 30, 2024 and December 31, 2023, segregated by the amount required for loans individually evaluated for impairment and the amount required for loans collectively evaluated for impairment: ​

​ ​ The Corporation’s methodology for estimating the ACL includes: Segmentation. The Corporation’s loan portfolio is segmented by homogeneous loan types that behave similarly to economic cycles. Specific Analysis. A specific reserve analysis is applied to certain individually evaluated loans. These loans are evaluated quarterly generally based on collateral value, observable market value or the present value of expected future cash flows. A specific reserve is established if the fair value is less than the loan balance. A charge-off is recognized when the loss is quantifiable. Individually evaluated loans not specifically analyzed reside in the Quantitative Analysis. Quantitative Analysis. The Corporation elected to use discounted cash flows. Economic forecasts include but are not limited to unemployment, the Consumer Price Index, the Housing Affordability Index, and Gross State Product. These forecasts are assumed to revert to the long term average and are utilized in the model to estimate the probability of default and the loss given default 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 assumption 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. Qualitative Analysis. Based on management’s review and analysis of internal, external and model risks, management may adjust the model output. Management reviews the peaks and troughs of the model’s calibrations, taking into account economic forecasts to develop guardrails that serve as the basis for determining the reasonableness of the model’s output and makes adjustments as necessary. This process challenges unexpected variability resulting from outputs beyond the model’s calibrations that appear to be unreasonable. Management also enhances the calculation through the use of Moody’s economic forecast data in its calculation. Additionally, management may adjust the economic forecast if it is incompatible with known market conditions based on management’s experience and perspective. The ACL is based on estimates, and actual losses may vary from current estimates. Management believes that the granularity of the homogeneous pools and the related historical loss ratios and other qualitative factors, as well as the consistency in the application of assumptions, result in an ACL that is representative of the risk found in the components of the portfolio at any given date. Credit Quality Indicators: The Corporation’s portfolio grading analysis estimates the capability of the borrower to repay the contractual obligations of the loan agreements as scheduled or at all. The Corporation’s internal credit risk grading system is based on debt service coverage, collateral values and other subjective factors. Mortgage and consumer loans are defaulted to pass grade until a loan migrates to past due status. The Corporation has a loan review policy and annual scope report that details the level of loan review for loans in a given year. The annual loan review provides the Credit Risk Committee with an independent analysis of the following: (i) credit quality of the loan portfolio; (ii) compliance with loan policy; (iii) adequacy of documentation in credit files; and (iv) validity of risk ratings. The Corporation’s internally assigned grades are as follows: Pass- The Corporation uses six grades of pass, including its watch rating. Generally, a pass rating indicates that the loan is currently performing and is of high quality. Special Mention- Assets with potential weaknesses that warrant management’s close attention and if left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date. Substandard- Assets that are inadequately protected by the current sound worth and paying capacity of the obligor or by the collateral pledged, if any. Assets so classified have a well-defined weakness, or weaknesses that jeopardize the liquidation of the debt. Such assets are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful- Assets with all weaknesses inherent in one classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently known facts, conditions, and values, highly questionable and improbable. Loss- Assets considered of such little value that its continuance on the books is not warranted. This classification does not mean that the asset has absolutely no recovery or salvage value, but rather it is not practical to defer writing off this basically worthless asset even though partial recovery may be affected in the future. The ability of borrowers to repay commercial loans is dependent upon the success of their business and general economic conditions. Due to the greater potential for loss within our commercial portfolio, we monitor the commercial loan portfolio through an internal risk rating system. Loan risk ratings are assigned based upon the creditworthiness of the borrower and are reviewed on an ongoing basis according to our internal policies. Loans rated special mention or substandard have potential or well-defined weaknesses not generally found in high quality, performing loans, and require attention from management to limit loss. ​ The following tables present loan balances by year of origination and internally assigned risk rating for our portfolio segments for the periods presented: ​

​ ​ Loan Modifications for Borrowers Experiencing Financial Difficulty ​ The Corporation evaluates all loan modifications according to the accounting guidance in ASU 2022-02 to determine if the modification results in a new loan or a continuation of the existing loan. Loan modifications to borrowers experiencing financial difficulties that result in a direct change in the timing or amount of contractual cash flows include situations where there is principal forgiveness, interest rate reductions, other-than-insignificant payment delays, term extensions, or combinations of the listed modifications. Therefore, the disclosures related to loan restructurings are for modifications which have a direct impact on cash flows. ​ The Corporation may offer various types of modifications when restructuring a loan. Commercial and industrial loans modified in a loan restructuring often involve temporary interest-only payments, term extensions, and converting credit lines to term loans. Additional collateral, a co-borrower, or a guarantor is often requested. ​ Commercial mortgage and construction loans modified in a loan restructuring often involve reducing the interest rate for the remaining term of the loan, extending the maturity date at an interest rate lower than the current market rate for new debt with similar risk, or substituting or adding a new borrower or guarantor. Construction loans modified in a loan restructuring may also involve extending the interest-only payment period. ​ Loans modified in a loan restructuring for the Corporation may have the financial effect of increasing the specific allowance associated with the loan. An allowance for loans that have been modified in a loan restructuring is measured based on the present value of expected cash flows discounted at the loan’s effective interest rate or the estimated fair value of the collateral, less any selling costs, if the loan is collateral dependent. Management exercises significant judgment in developing these estimates. ​ Commercial and consumer loans modified in a loan restructuring are closely monitored for delinquency as an early indicator of possible future default. If loans modified in a loan restructuring subsequently default, the Corporation evaluates the loan for possible further loss. The allowance may be increased, adjustments may be made in the allocation of the allowance, or partial charge-offs may be taken to further write-down the carrying value of the loan. ​ The following tables present the amortized cost basis as of September 30, 2024 and the financial effect of loans modified to borrowers experiencing financial difficulty during the nine- and three-month periods ended September 30, 2024: ​

​ There were no loan modifications made to borrowers experiencing financial difficulty during the nine- or three-month periods ended September 30, 2023. ​ The Corporation monitors loan payments on performing and non-performing loans on an ongoing basis to determine if a loan is considered to have a payment default. The loans that were modified in the nine- and three-month periods ended September 30, 2024 have made all contractual payments. ​ If a modified loan with an outstanding balance of $0.1 million or greater subsequently defaults and goes on non-accrual status, then the Corporation individually evaluates the loan when performing its CECL estimate to calculate the ACL. Upon determination that a modified loan (or a portion of a modified loan) has subsequently been deemed uncollectible, the loan (or portion of the loan) is charged off. Therefore, the amortized cost basis of the loan is reduced by the uncollectible amount and the ACL is adjusted by the same amount.
