LOANS AND ALLOWANCE | LOANS AND ALLOWANCE Loan Portfolio and Credit Quality The Corporation's primary lending focus is small business and middle market commercial, commercial real estate, public finance and residential real estate, which results in portfolio diversification. The following tables show the composition of the loan portfolio and credit quality characteristics by collateral classification, excluding loans held for sale. Loans held for sale at June 30, 2024 and December 31, 2023, were $32.3 million and $18.9 million, respectively. The following table illustrates the composition of the Corporation’s loan portfolio by loan class as of the dates indicated:
| June 30, 2024 |  | December 31, 2023
Commercial and industrial loans | $ | 3,949,817 |  |  | $ | 3,670,948 |
Agricultural land, production and other loans to farmers | 239,926 |  |  | 263,414 |

Construction | 823,267 |  |  | 957,545 |
Commercial real estate, non-owner occupied | 2,323,533 |  |  | 2,400,839 |
Commercial real estate, owner occupied | 1,174,195 |  |  | 1,162,083 |
Residential | 2,370,905 |  |  | 2,288,921 |
Home equity | 631,104 |  |  | 617,571 |

Credit Quality As part of the ongoing monitoring of the credit quality of the Corporation's loan portfolio, management tracks certain credit quality indicators including trends related to: (i) the level of criticized commercial loans, (ii) net charge-offs, (iii) nonperforming loans, (iv) covenant failures and (v) the general national and local economic conditions. The Corporation utilizes a risk grading of pass, special mention, substandard, doubtful and loss to assess the overall credit quality of large commercial loans. All large commercial credit grades are reviewed at a minimum of once a year for pass grade loans. Loans with grades below pass are reviewed more frequently depending on the grade. A description of the general characteristics of these grades is as follows: •Pass - Loans that are considered to be of acceptable credit quality. •Special Mention - Loans which possess some credit deficiency or potential weakness, which deserves close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Corporation's credit position at some future date. Special mention assets are not adversely classified and do not expose the Corporation to sufficient risk to warrant adverse classification. •Substandard - Loans that are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified have a well-defined weakness that jeopardizes the liquidation of the debt. They are characterized by the distinct possibility that the Corporation will sustain some loss if the deficiencies are not corrected. •Doubtful - Loans that have all of the weaknesses of those classified as Substandard. However, based on currently existing facts, conditions and values, these weaknesses make full collection of principal highly questionable and improbable. •Loss – Loans that are considered uncollectible and of such little value that continuing to carry them as an asset is not warranted. Loans will be classified as Loss when it is neither practical or desirable to defer charging-off or reserving all or a portion of a basically worthless asset, even though partial recovery may be possible at some time in the future. The following tables summarize the risk grading of the Corporation’s loan portfolio and gross charge-offs by loan class and by year of origination for the periods indicated. Consumer loans are not risk graded. For the purposes of this disclosure, the consumer loans are classified in the following manner: loans that are less than 30 days past due are Pass, loans 30-89 days past due are Special Mention and loans greater than 89 days past due are Substandard. The entire balance of a loan is considered delinquent if the minimum payment contractually required to be made is not received by the specified due date.

Loans are reclassified to a nonaccruing status when, in management’s judgment, the collateral value and financial condition of the borrower do not justify accruing interest. At the time the accrual is discontinued, all unpaid accrued interest is reversed against earnings. Interest income accrued in prior years, if any, is charged to the allowance for credit losses. Payments subsequently received on nonaccrual loans are applied to principal. A loan is returned to accrual status when principal and interest are no longer past due and collectability is probable, typically after a minimum of six consecutive months of performance. The following table summarizes the Corporation’s nonaccrual loans by loan class as of the dates indicated:
| June 30, 2024 |  | December 31, 2023 |

Interest income on nonaccrual loans is recognized only to the extent that cash payments are received in excess of principal due. There was no interest income recognized on nonaccrual loans for the three and six months ended June 30, 2024 or 2023. Determining fair value for collateral dependent loans requires obtaining a current independent appraisal of the collateral and applying a discount factor, which includes selling costs if applicable, to the value. The fair value of real estate is generally based on appraisals by qualified licensed appraisers. The appraisers typically determine the value of the real estate by utilizing an income or market valuation approach. If an appraisal is not available, the fair value may be determined by using a cash flow analysis. Fair value on other collateral such as business assets is typically ascertained by assessing, either singularly or some combination of, asset appraisals, accounts receivable aging reports, inventory listings and or customer financial statements. Both appraised values and values based on borrower’s financial information are discounted as considered appropriate based on age and quality of the information and current market conditions. The tables below present the amortized cost basis of collateral dependent loans by loan class and their respective collateral type, which are individually evaluated to determine expected credit losses. The total collateral dependent loan balance increased $5.0 million, primarily related to an increase of $8.1 million in commercial real estate, non-owner occupied, offset by a decrease of $3.4 million in commercial and industrial, for the six months ended June 30, 2024. The total related allowance balance decreased $612,000, primarily related to a decrease of $3.0 million in commercial and industrial, offset by an increase of $2.4 million in commercial real estate, non-owner occupied, for the six months ended June 30, 2024.

Upon the Corporation's determination that a modified loan (or portion of a 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 allowance for credit losses is adjusted by the same amount. Allowance for Credit Losses on Loans The Allowance for Credit Losses on Loans ("ACL - Loans") is a valuation account that is deducted from the amortized cost basis of loans to present the net amount expected to be collected on loans over the contractual term. The ACL - Loans is adjusted by the provision for credit losses, which is reported in earnings, and reduced by charge-offs for loans, net of recoveries. Provision for credit losses on loans reflects the totality of actions taken on all loans for a particular period including any necessary increases or decreases in the allowance related to changes in credit loss expectations associated with specific loans or pools of loans. Loans are charged-off against the allowance when the uncollectibility of the loan is confirmed. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. The allowance represents the Corporation’s best estimate of current expected credit losses on loans using relevant available information, from internal and external sources, related to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. The CECL calculation is performed and evaluated quarterly and losses are estimated over the expected life of the loan. The level of the allowance for credit losses is believed to be adequate to absorb all expected future losses inherent in the loan portfolio at the measurement date. In calculating the allowance for credit losses, the loan portfolio was pooled into ten loan segments with similar risk characteristics. Common characteristics include the type or purpose of the loan, underlying collateral and historical/expected credit loss patterns. In developing the loan segments, the Corporation analyzed the degree of correlation in how loans within each portfolio respond when subjected to varying economic conditions and scenarios as well as other portfolio stress factors. The expected credit losses are measured over the life of each loan segment utilizing the Probability of Default / Loss Given Default methodology combined with economic forecast models to estimate the current expected credit loss inherent in the loan portfolio. This approach is also leveraged to estimate the expected credit losses associated with unfunded loan commitments incorporating expected utilization rates. The Corporation sub-segmented certain commercial portfolios by risk level and certain consumer portfolios by delinquency status where appropriate. The Corporation utilized a four-quarter reasonable and supportable economic forecast period followed by a six-quarter, straight-line reversion period to the historical macroeconomic mean for the remaining life of the loans. Econometric modeling was performed using historical default rates and a selection of economic forecast scenarios published by Moody’s to develop a range of estimated credit losses for which to determine the best credit loss estimate within. Macroeconomic factors utilized in the modeling process include the national unemployment rate, BBB US corporate index, Commercial Real Estate ("CRE") price index and the home price index. The Corporation qualitatively adjusts model results for risk factors that are not inherently considered in the quantitative modeling process, but are nonetheless relevant in assessing the expected credit losses within the loan portfolio. These adjustments may increase or decrease the estimate of expected credit losses based upon the assessed level of risk for each qualitative factor. The various risks that may be considered in making qualitative adjustments include, among other things, the impact of (i) changes in the nature and volume of the loan portfolio, (ii) changes in the existence, growth and effect of any concentrations in credit, (iii) changes in lending policies and procedures, including changes in underwriting standards and practices for collections, charge-offs, and recoveries, (iv) changes in the quality of the credit review function, (v) changes in the experience, ability and depth of lending, investment, collection and other relevant management staff, (vi) changes in the volume and severity of past due financial assets, the volume of the nonaccrual assets, and the volume and severity of adversely classified or graded assets, (vii) the value of underlying collateral for loans that are not collateral dependent, and (viii) other environmental factors such as regulatory, legal and technological considerations, as well as competition and changes in the economic and business conditions that affect the collectibility of financial assets. At CECL adoption, the Corporation established certain qualitative factors that were expected to correlate to losses within the loan portfolio. During a scheduled review of qualitative factors in 2023, the Corporation determined there had not been significant evidence of correlation to losses for the qualitative factors that included i) changes in experience, ability and depth of lending management and staff; ii) changes in lending policies and procedures; iii) changes in the quality of the credit review function; iv) portfolio mix and growth; and v) industry concentration. The Corporation decided to refine these qualitative factors in order to improve our ability to assess related risk and enhance our ability to correlate to losses. The Corporation’s evaluation of the qualitative approach resulted in an insignificant change to the ACL – Loans estimate. In some cases, management may determine that an individual loan exhibits unique risk characteristics which differentiate the loan from other loans within the loan segments. In such cases, the loans are evaluated for expected credit losses on an individual basis and excluded from the collective evaluation. Specific reserve allocations of the allowance for credit losses are determined by analyzing the borrower’s ability to repay amounts owed, collateral deficiencies, the relative risk grade of the loan and economic conditions affecting the borrower’s industry, among other things. A loan is considered to be collateral dependent when, based upon management's assessment, the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. In such cases, expected credit losses are based on the fair value of the collateral at the measurement date, adjusted for estimated selling costs if satisfaction of the loan depends on the sale of the collateral. The fair value of collateral supporting collateral dependent loans is evaluated on a quarterly basis. The risk characteristics of the Corporation’s portfolio segments are as follows: Commercial Commercial lending is primarily based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not be as expected and the collateral securing these loans may fluctuate in value. Most commercial loans are secured by the tangible assets being financed such as equipment or real estate or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee. Other loans may be unsecured, secured but under-collateralized or otherwise made on the basis of the enterprise value of an organization. In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its customers. Commercial real estate Commercial real estate loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts and the repayment of these loans is generally dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. The Corporation monitors commercial real estate loans based on collateral and risk grade criteria, as well as the levels of owner-occupied versus non-owner occupied loans. Construction Construction loans are underwritten utilizing a combination of tools and techniques including feasibility and market studies, independent appraisals and appraisal reviews, absorption and interest rate sensitivity analysis as well as the financial analysis of the developer and all guarantors. Construction loans are monitored by either in house or third party inspectors limiting advances to a percentage of costs or stabilized project value. These loans frequently involve the disbursement of significant funds with the repayment dependent upon the successful completion and, where necessary, the future stabilization of the project. The predominant inherent risk of this portfolio is associated with the borrower's ability to successfully complete a project on time, within budget and stabilize the projected as originally projected. Consumer and Residential With respect to residential loans that are secured by 1-4 family residences, which are typically owner occupied, the Corporation generally establishes a maximum loan-to-value ratio and requires private mortgage insurance if that ratio is exceeded. Home equity loans are secured by a subordinate interest in 1-4 family residences, and consumer loans are secured by consumer assets such as automobiles or recreational vehicles. Some consumer loans, such as small installment loans and certain lines of credit, are unsecured. Repayment of these loans is primarily dependent on the personal income and credit rating of the borrowers and can also be impacted by changes in property values. Risk is mitigated by the fact that the loans are of smaller individual amounts and spread over a large number of borrowers. The allowance for credit losses decreased $15.1 million and $15.4 million during the three and six months ended June 30, 2024, respectively. Net charge-offs totaled $39.6 million and $41.9 million during the three and six months ended June 30, 2024, respectively. Provision expense of $24.5 million and $26.5 million was recorded during the three and six months ended June 30, 2024, respectively.

Off-Balance Sheet Arrangements, Commitments And Contingencies In the normal course of business, the Corporation has entered into off-balance sheet financial instruments which include commitments to extend credit and standby letters of credit. Commitments to extend credit are usually the result of lines of credit granted to existing borrowers under agreements that the total outstanding indebtedness will not exceed a specific amount during the term of the indebtedness. Typical borrowers are commercial customers that use lines of credit to supplement their treasury management functions, and thus their total outstanding indebtedness may fluctuate during any time period based on the seasonality of their business and the resultant timing for their cash flows. Other typical lines of credit are related to home equity loans granted to customers. Commitments to extend credit generally have fixed expiration dates or other termination clauses that may require a fee. Standby letters of credit are generally issued on behalf of an applicant (the Corporation’s customer) to a specifically named beneficiary and are the result of a particular business arrangement that exists between the applicant and the beneficiary. Standby letters of credit have fixed expiration dates and are usually for terms of two years or less unless terminated beforehand due to criteria specified in the standby letter of credit. The standby letter of credit would permit the beneficiary to obtain payment from the Corporation under certain prescribed circumstances. Subsequently, the Corporation would seek reimbursement from the applicant pursuant to the terms of the standby letter of credit. The Corporation typically follows the same credit policies and underwriting practices when making these commitments as it does for on-balance sheet instruments. Each customer’s creditworthiness is typically evaluated on a case-by-case basis, and the amount of collateral obtained, if any, is based on management’s credit evaluation of the customer. Collateral held varies but may include cash, real estate, marketable securities, accounts receivable, inventory, equipment and personal property. The contractual amounts of these commitments are not reflected in the consolidated financial statements and only amounts drawn upon would be reflected in the future. Since many of the commitments are expected to expire without being drawn upon, the contractual amounts do not necessarily represent future cash requirements. However, should the commitments be drawn upon and should the Corporation’s customers default on their resulting obligation to the Corporation, the maximum exposure to credit loss, without consideration of collateral, is represented by the contractual amount of those commitments. Financial instruments with off-balance sheet risk were as follows:
| June 30, 2024 |  | December 31, 2023
Amounts of commitments: |  |  |
Loan commitments to extend credit | $ | 5,271,982 |  |  | $ | 5,025,790 |
Standby letters of credit | $ | 69,618 |  |  | $ | 65,580 |
The Corporation maintains an accrual for credit losses on off-balance sheet commitments using the CECL methodology. Reserves for unfunded commitments declined by $3.8 million during the year ended December 31, 2023, which decreased the reserve to $19.5 million at December 31, 2023 and June 30, 2024. This reserve level remains appropriate and is reported in Other Liabilities as of June 30, 2024 in the Consolidated Condensed Balance Sheets. The table below reflects the total allowance for credit losses for the off-balance sheet commitment for the three and six months ended June 30, 2024 and 2023:
