The following table presents credit quality indicators for the credit loss portfolio segments and classes. These categories are utilized to develop the associated allowance for credit losses using historical losses adjusted for current economic conditions defined as follows: ● Pass – loans which are well protected by the current net worth and paying capacity of the obligor (or obligors, if any) or by the fair value, less cost to acquire and sell, of any underlying collateral. ● Special Mention – loans with potential weakness that may, if not reversed or corrected, weaken the credit or inadequately protect the Company’s position at some future date. These loans are not adversely classified and do not expose an institution to sufficient risk to warrant an adverse classification. ● Substandard – loans that exhibit well-defined weakness or weaknesses that presently jeopardize debt repayment. These loans are characterized by the distinct possibility that the institution will sustain some loss if the weaknesses are not corrected. ● Doubtful – loans that have all the weaknesses inherent in loans classified substandard, plus the added characteristic that the weaknesses make collection or liquidation in full on the basis of currently existing facts, conditions, and values highly questionable and improbable.

For loans that do not share similar risk characteristics with the collectively evaluated pools, evaluations are performed on an individual basis. For all loan segments collectively evaluated, losses are predicted over a period of time determined to be reasonable and supportable, and at the end of the reasonable and supportable forecast period losses are reverted to long-term historical averages. The estimated loan losses for all loan segments are adjusted for changes in qualitative factors not inherently considered in the quantitative analyses. The Company uses the discounted cash flow (“DCF”) method to estimate ACL for all loan pools except for commercial and industrial ("C&I") revolving lines of credit and credit cards. C&I revolving lines of credit and credit cards are members of the Commercial, financial and agricultural and Consumer portfolios, respectively. For all loan pools utilizing the DCF method, the Company utilizes and forecasts national unemployment rate as a loss driver. The Company also utilizes and forecasts GDP growth as a second loss driver for its agricultural and consumer loan pools. Consistent forecasts of the loss drivers are used across the loan segments. At September 30, 2024 and December 31, 2023, the Company utilized a reasonable and supportable forecast period of twelve months followed by a six-month straight-line reversion to long term averages. The Company leveraged economic projections from reputable and independent sources to inform its loss driver forecasts. The Company expects the national unemployment rate to fall and the national GDP growth rate to rise compared to the December 31, 2023 forecast. The Company uses a loss-rate method to estimate expected credit losses for its C&I revolving lines of credit and credit card pools. The C&I revolving lines of credit pool incorporates a probability of default (“PD”) and loss given default (“LGD”) modeling approach. This approach involves estimating the pool average life and then using historical correlations of default and loss experience over time to calculate the lifetime PD and LGD. These two inputs are then applied to the outstanding pool balance. The credit card pool incorporates a remaining life modeling approach, which utilizes an attrition-based method to estimate the remaining life of the pool. A quarterly average loss rate is then calculated using the Company’s historical loss data. The model reduces the pool balance quarterly on a straight-line basis over the estimated life of the pool. The quarterly loss rate is multiplied by the outstanding balance at each period-end resulting in an estimated loss for each quarter. The sum of estimated loss for all quarters is the total calculated reserve for the pool. Management has applied the loss-rate method to C&I lines of credit and to credit cards due to their generally short-term nature. An expected loss ratio is applied based on internal and peer historical losses. Each loan pool is adjusted for qualitative factors not inherently considered in the quantitative analyses. The qualitative adjustments either increase or decrease the quantitative model estimation. The Company considers factors that are relevant within the qualitative framework which include the following: lending policy, changes in nature and volume of loans, staff experience, changes in volume and trends of problem loans, concentration risk, trends in underlying collateral values, external factors, quality of loan review system and other economic conditions. Inherent risks in the loan portfolio will differ based on type of loan. Specific risk characteristics by loan portfolio segment are listed below: Commercial, financial and agricultural loans Real estate construction loans Real estate mortgage loans Consumer loans The following table presents changes in the ACL, segregated by loan type, for the three and nine months ended September 30, 2024 and 2023.

The allowance is computed using a methodology similar to that used to determine the ACL for loans, modified to take into account the probability of a drawdown on the commitment. The ACL on unfunded loan commitments is classified as a liability account on the Consolidated Balance Sheet within other liabilities, while the corresponding provision for these credit losses is recorded as a component of other expense. During the third quarter of 2024, we reclassified the provision for Unfunded Commitments from Other Expenses to Provision for Credit Losses. The ACL on unfunded commitments was $1.3 million at September 30, 2023, and $575,000 at December 31, 2023. The provision expense for unfunded commitments was $239,000 and $726,000 for the three and nine months ended September 30, 2024, respectively.

Fair Value Disclosures [Text Block]	NOTE 11 - FAIR VALUE MEASUREMENT Measurement of fair value under U.S. GAAP establishes a hierarchy that prioritizes observable and unobservable inputs used to measure fair value, as of the measurement date, into three broad levels, which are described below: Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs. Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data. Level 3: Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible and also considers counterparty credit risk in its assessment of fair value. Debt Securities. Derivative instruments. Loans Individually Evaluated. Other Real Estate Owned There were five residential real estate loans with a balance of $519,000 foreclosed and classified as OREO as of September 30, 2024, compared to three residential real estate loan foreclosures for $360,000 as of December 31, 2023. Three residential real estate loans totaling $509,000 were in the process of being foreclosed as of September 30, 2024. There were three residential real estate loans for $292,000 that were in the process of being foreclosed as of December 31, 2023.

Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. Current U.S. GAAP excludes certain financial instruments and all nonfinancial instruments from its fair value disclosure requirements. Accordingly, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company. The estimated fair values of the Company’s financial instruments not measured at fair value on a recurring or non-recurring basis as of September 30, 2024 and December 31, 2023 were as follows: September 30, 2024 December 31, 2023 Carrying Carrying Amount Fair Value Amount Fair Value (In Thousands) Financial Assets: Level 1 Inputs: Cash and cash equivalents $ 1,756,689 $ 1,756,689 $ 2,030,513 $ 2,030,513 Held to maturity U.S. Treasury securities 249,349 233,123 508,985 484,267 Level 2 Inputs: Federal funds sold 3,542 3,542 100,575 100,575 Held to maturity debt securities 478,981 439,650 473,429 422,674 Mortgage loans held for sale 8,453 8,453 5,071 5,071 Restricted equity securities 11,300 11,300 10,226 10,226 Level 3 Inputs: Held to maturity debt securities 250 250 250 250 Loans, net 12,177,471 11,826,898 11,505,512 11,032,819 Financial Liabilities: Level 2 Inputs: Deposits $ 13,146,529 $ 13,145,438 $ 13,273,511 $ 13,266,640 Federal funds purchased 1,542,623 1,542,623 1,256,724 1,256,724 Other borrowings 64,741 58,861 64,735 58,083
