In the opinion of management, all adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2024 are not necessarily indicative of the results that are expected for the year ended December 31, 2024. The condensed consolidated balance sheet of the Company as of December 31, 2023, has been derived from the audited consolidated balance sheet of the Company as of that date. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and footnotes thereto included in the Farmers & Merchants Bancorp, Inc. (the "Company")'s Annual Report on Form 10-K for the year ended December 31, 2023.

The Company’s principal source of revenue is interest income from loans and investment securities. The Company also earns noninterest income from various banking and financial services offered primarily through Farmers & Merchants State Bank (the "Bank"). Interest income is primarily recognized on an accrual basis according to nondiscretionary formulas written in contracts, such as loan agreements or investment security contracts. The Company also earns noninterest income from various banking and financial services provided to business and consumer clients such as deposit account, debit card, and mortgage banking services. Revenue is recorded for noninterest income based on the contractual terms for the service or transaction performed.

PPSF shareholders had the opportunity to elect to receive either 0.6597 shares of Farmers & Merchants Bancorp, Inc. (FMAO) stock or $ 24.00 per share in cash for each PPSF share owned, subject to a requirement under the Merger Agreement that the minimum number of PPSF shares exchanged for FMAO shares in the merger was no less than 758,566 . Fractional shares of FMAO common stock were not issued in respect of fractional interests arising from the merger but were paid in cash pursuant to the merger agreement. PPSF had 1,167,025 shares outstanding on October 1, 2022. The share price of FMAO stock on October 1, 2022 was $ 26.87 . Total consideration for the acquisition was approximately $ 23.2 million of which $ 9.8 million was in cash and $ 13.4 million in stock. As a result of the acquisition, the Company increased its deposit base in Sidney and the greater Shelby County and reduced transaction costs. The Company has reduced costs through economies of scale. Under the acquisition method of accounting, the total purchase was allocated to net tangible and intangible assets based on their current estimated fair values on the date of acquisition. Of the total purchase price of $ 23.2 million, $ 6.0 million has been allocated to core deposit intangible included in other assets and is being amortized over seven years on a straight line basis. Goodwill of $ 5.9 million, which resulted from the acquisition, consists largely of the synergies and economies of scale expected from combining the operations of the Company and Peoples Federal Savings and Loan Association. Of that total amount, none of the purchase price is deductible for tax purposes.

Securities	NOTE 3 SECURITIES Mortgage-backed securities, as shown in the following tables, are all government sponsored enterprises. The amortized cost and fair value of securities, with gross unrealized gains and losses at March 31, 2024 and December 31, 2023, are as follows: (In Thousands) March 31, 2024 Amortized Gross Unrealized Gross Unrealized Fair Cost Gains Losses Value Available-for-Sale: U.S. Treasury $ 81,842 $ - $ ( 7,149 ) $ 74,693 U.S. Government agencies 140,928 - ( 13,190 ) 127,738 Mortgage-backed securities 91,485 - ( 13,081 ) 78,404 State and local governments 71,981 87 ( 5,387 ) 66,681 Total available-for-sale securities $ 386,236 $ 87 $ ( 38,807 ) $ 347,516 (In Thousands) December 31, 2023 Amortized Gross Unrealized Gross Unrealized Fair Cost Gains Losses Value Available-for-Sale: U.S. Treasury $ 87,182 $ 1 $ ( 6,913 ) $ 80,270 U.S. Government agencies 140,960 - ( 12,738 ) 128,222 Mortgage-backed securities 94,061 - ( 11,929 ) 82,132 State and local governments 73,000 135 ( 5,281 ) 67,854 Total available-for-sale securities $ 395,203 $ 136 $ ( 36,861 ) $ 358,478 Investment securities will at times depreciate to an unrealized loss position. The Company utilizes the following criteria to assess whether the unrealized loss requires an allowance for credit losses on investment securities. No one item by itself will necessarily signal that an allowance for credit losses on investment securities should be established. 1. The fair value of the security has significantly declined from book value. 2. A downgrade has occurred that lowered the credit rating to below investment grade (below Baa3 by Moody and BBB – by Standard and Poors.) 3. Dividends have been reduced or eliminated or scheduled interest payments have not been made. 4. Management does not possess both the intent and ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value. If the unrealized loss is determined to be the result of a credit loss, the present value of the cash flows expected to be collected is compared to the amortized cost basis. If the present value of the cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded, limited by the amount that the fair value is less than the amortized cost basis. Adjustments to the allowance are recorded in the Company's consolidated statement of income as a component of the provision for credit losses. The table below is presented by category of security and length of time in a continuous loss position. The Company did not record an allowance for credit losses on its investment securities available for sale as the unrealized losses were attributable to changes in interest rates, not credit quality. Information pertaining to securities with gross unrealized losses at March 31, 2024 and December 31, 2023, aggregated by investment category and length of time that individual securities have been in a continuous loss position follows: (In Thousands) March 31, 2024 Less Than Twelve Months Twelve Months & Over Total Gross Unrealized Fair Gross Unrealized Fair Gross Unrealized Fair Losses Value Losses Value Losses Value U.S. Treasury $ ( 3 ) $ 561 $ ( 7,146 ) $ 74,132 $ ( 7,149 ) $ 74,693 U.S. Government agencies - - ( 13,190 ) 127,738 ( 13,190 ) 127,738 Mortgage-backed securities ( 33 ) 4,321 ( 13,048 ) 74,083 ( 13,081 ) 78,404 State and local governments ( 38 ) 1,245 ( 5,349 ) 59,278 ( 5,387 ) 60,523 Total available-for-sale securities $ ( 74 ) $ 6,127 $ ( 38,733 ) $ 335,231 $ ( 38,807 ) $ 341,358 (In Thousands) December 31, 2023 Less Than Twelve Months Twelve Months & Over Total Gross Unrealized Fair Gross Unrealized Fair Gross Unrealized Fair Losses Value Losses Value Losses Value U.S. Treasury $ ( 4 ) $ 494 $ ( 6,909 ) $ 79,528 $ ( 6,913 ) $ 80,022 U.S. Government agencies - - ( 12,738 ) 128,222 ( 12,738 ) 128,222 Mortgage-backed securities ( 20 ) 4,372 ( 11,909 ) 77,759 ( 11,929 ) 82,131 State and local governments ( 2 ) 931 ( 5,279 ) 60,402 ( 5,281 ) 61,333 Total available-for-sale securities $ ( 26 ) $ 5,797 $ ( 36,835 ) $ 345,911 $ ( 36,861 ) $ 351,708 Unrealized losses on securities have not been recognized into income because the issuers’ bonds are of high credit quality, values have only been impacted by changes in interest rates since the securities were purchased, and the Company has the intent and ability to hold the securities for the foreseeable future. The fair value is expected to recover as the bonds approach the maturity date. Below are the gross realized gains and losses for the three months ended March 31, 2024 and March 31, 2023.

The Company recognized $ 22 thousand and $ 61 thousand of interest income on nonaccrual loans for the three months ending March 31, 2024 and March 31, 2023, respectively. Following are the characteristics and underwriting criteria for each major type of loan the Bank offers: Consumer Real Estate: Purchase, refinance, or equity financing of one to four family owner occupied dwelling. Success in repayment is subject to borrower’s income, debt level, character in fulfilling payment obligations, employment, and others. Agricultural Real Estate: Purchase of farm real estate or for permanent improvements to the farm real estate. Cash flow from the farm operation is the repayment source and is therefore subject to the financial success of the farm operation. Agricultural: Loans for the production and housing of crops, fruits, vegetables, and livestock or to fund the purchase or re-finance of capital assets such as machinery and equipment and livestock. The production of crops and livestock is especially vulnerable to commodity prices and weather. The vulnerability to commodity prices is offset by the farmer’s ability to hedge their position by the use of the future contracts. The risk related to weather is often mitigated by requiring crop insurance. Commercial Real Estate: Construction, purchase, and refinance of business purpose real estate. Risks include potential construction delays and overruns, vacancies, collateral value subject to market value fluctuations, interest rate, market demands, borrower’s ability to repay in orderly fashion, and others. The Bank does employ stress testing on higher balance loans to mitigate risk by ensuring the customer’s ability to repay in a changing rate environment before granting loan approval. Commercial and Industrial: Loans to proprietorships, partnerships, or corporations to provide temporary working capital and seasonal loans as well as long term loans for capital asset acquisition. Risks include adequacy of cash flow, reasonableness of projections, financial leverage, economic trends, management ability and estimated capital expenditures during the fiscal year. The Bank does employ stress testing on higher balance loans to mitigate risk by ensuring the customer's ability to repay in a changing rate environment before granting loan approval. Consumer: Funding for individual and family purposes. Success in repayment is subject to borrower’s income, debt level, character in fulfilling payment obligations, employment, and other factors. Other: Primarily funds public improvements in the Bank’s service area. Repayment ability is based on the continuance of the taxation revenue as the source of repayment. The Bank uses a nine tier risk rating system to grade its loans. The grade of a loan may change during the life of the loan. The risk ratings are described as follows. 1. Zero (0) Unclassified. Any loan which has not been assigned a classification. 2. One (1) Excellent. Credit to premier customers having the highest credit rating based on an extremely strong financial condition, which compares favorably with industry standards (upper quartile of RMA ratios). Financial statements indicate a sound earnings and financial ratio trend for several years with satisfactory profit margins and excellent liquidity exhibited. Prime credits may also be borrowers with loans fully secured by highly liquid collateral such as traded stocks, bonds, certificates of deposit, savings account, etc. No credit or collateral exceptions exist, and the loan adheres to The Bank's loan policy in every respect. Financing alternatives would be readily available and would qualify for unsecured credit. This rate is summarized by high liquidity, minimum risk, strong ratios, and low handling costs. 3. Two (2) Good. Desirable loans of somewhat less stature than rate 1, but with strong financial statements. Loan supported by financial statements containing strong balance sheets and a history of profitability. Probability of serious financial deterioration is unlikely. Possessing a sound repayment source (and a secondary source), which would allow repayment in a reasonable period of time. Individual loans backed by liquid personal assets, established history and unquestionable character. 4. Three (3) Satisfactory. Satisfactory loans of average or slightly above average risk – having some deficiency or vulnerability to changing economic conditions, but still fully collectible. Projects should normally demonstrate acceptable debt service coverage. There may be some weakness but with offsetting features of other support readily available. Loans that are meeting the terms of repayment. Loans may be rated 3 when there is no recent information on which to base a current risk evaluation and the following conditions apply: At inception, the loan was properly underwritten and did not possess an unwarranted level of credit risk; a. At inception, the loan was secured with collateral possessing a loan-to-value adequate to protect The Bank from loss; b. The loan exhibited two or more years of satisfactory repayment with a reasonable reduction of the principal balance; c. During the period that the loan has been outstanding, there has been no evidence of any credit weakness. Some examples of weakness include slow payment, lack of cooperation by the borrower, breach of loan covenants, or the business is in an industry which is known to be experiencing problems. If any of these credit weaknesses is observed, a lower risk rating is warranted. 5. Four (4) Satisfactory / Monitored. A “4” (Satisfactory/Monitored) risk rating may be established for a loan considered satisfactory but which is of average credit risk due to financial weakness or uncertainty. The loans warrant a higher than average level of monitoring to ensure that weaknesses do not advance. The level of risk in Satisfactory/Monitored classification is considered acceptable and within normal underwriting guidelines, so long as the loan is given management supervision. 6. Five (5) Special Mention. Loans that possess some credit deficiency or potential weakness which deserve close attention, but which do not yet warrant substandard classification. Such loans pose unwarranted financial risk that, if not corrected, could weaken the loan and increase risk in the future. The key distinctions of a 5 (Special Mention) classification are that (1) it is indicative of an unwarranted level of risk, and (2) weaknesses are considered “potential” versus “defined” impairments to the primary source of loan repayment and collateral. 7. Six (6) Substandard. One or more of the following characteristics may be exhibited in loans classified substandard: a. Loans which possess a defined credit weakness and the likelihood that a loan will be paid from the primary source are uncertain. Financial deterioration is underway and very close attention is warranted to ensure that the loan is collected without loss. b. Loans are inadequately protected by the current net worth and paying capacity of the borrower. c. The primary source of repayment is weakened, and The Bank is forced to rely on a secondary source of repayment such as collateral liquidation or guarantees. d. Loans are characterized by the distinct possibility that The Bank will sustain some loss if deficiencies are not corrected. e. Unusual courses of action are needed to maintain a high probability of repayment. f. The borrower is not generating enough cash flow to repay loan principal; however, continues to make interest payments. g. The lender is forced into a subordinate position or unsecured collateral position due to flaws in documentation. h. Loans have been restructured so that payment schedules, terms and collateral represent concessions to the borrower when compared to the normal loan terms. i. The lender is seriously contemplating foreclosure or legal action due to the apparent deterioration in the loan. j. There is significant deterioration in the market conditions and the borrower is highly vulnerable to these conditions. 8. Seven (7) Doubtful. One or more of the following characteristics may be exhibited in loans classified Doubtful: a. Loans have all of the weaknesses of those classified as Substandard. Additionally, however, these weaknesses make collection or liquidation in full based on existing conditions improbable. b. The primary source of repayment is gone, and there is considerable doubt as to the quality of the secondary source of repayment. c. The possibility of loss is high, but, because of certain important pending factors which may strengthen the loan, loss classification is deferred until its exact status is known. A Doubtful classification is established deferring the realization of the loss. 9. Eight (8) Loss. Loans are considered uncollectable and of such little value that continuing to carry them as assets on the institution’s financial statements is not feasible. Loans will be classified Loss when it is neither practical nor desirable to defer writing 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 modifications normally do not result in the contractual forgiveness of principal. During the three months ended March 31, 2024 and March 31, 2023 , there were no new loan modifications to borrowers experiencing financial difficulty. One modified loan previous to 2024 was paid off during the first quarter of 2024. One modification completed prior to 2024 was paid off during the first quarter of 2024. For the three months ended March 31, 2024 and 2023 , there were no modifications to borrowers experiencing financial difficulty that subsequently defaulted after modification. For the majority of the Bank’s collateral dependent loans, the Bank applied the fair value of collateral or used a measurement incorporating the present value of expected future cash flows discounted at the loan’s effective rate of interest. To determine fair value of collateral, collateral asset values securing a collateral dependent loan were periodically evaluated. Maximum time of re-evaluation was every 12 months for chattels and titled vehicles and every two years for real estate. In this process, third party evaluations were obtained. Until such time that updated appraisals were received, the Bank may have discounted the collateral value used. The Bank used the following guidelines as stated in policy to determine when to realize a charge-off, whether a partial or full loan balance. A charge-off in whole or in part was realized when unsecured consumer loans and overdraft lines of credit reached 90 days delinquency. At 90 days delinquent, secured consumer loans were charged down to the value of the collateral, if repossession of the collateral was assured and/or in the process of repossession. Consumer mortgage loan deficiencies were charged down upon the sale of the collateral or sooner upon the recognition of collateral deficiency. A broker’s price opinion or appraisal was completed on all home loans in litigation and any deficiency was charged off before reaching 150 days delinquent. Commercial and agricultural credits were charged down/allocated at 120 days delinquency, unless an established and approved work-out plan was in place or litigation of the credit was likely to result in recovery of the loan balance. Upon notification of bankruptcy, unsecured debt was charged off. Additional charge-off was realized as further unsecured positions were recognized. As of March 31, 2024 , the Company had no foreclosed residential real estate property obtained by physical possession and $ 270 thousand of consumer mortgage loans secured by residential real estate properties for which foreclosure proceedings are in process according to local jurisdictions. This compares to the Company having no foreclosed residential real estate property obtained by physical possession and $ 679 thousand of consumer mortgage loans secured by residential real estate properties for which foreclosure proceeding were in process according to local jurisdictions as of December 31, 2023. As of March 31, 2023 , the Company had no foreclosed residential real estate property obtained by physical possession and $ 52 thousand of consumer mortgage loans secured by residential real estate properties for which foreclosure proceedings were in process according to local jurisdictions. On January 1, 2023, the Company adopted Accounting Standards Update ("ASU") No. 2016-13 - "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" and implemented the current expected credit losses accounting standard. As a result, the Company recorded a one-time adjustment from equity into the allowance for credit losses for loan losses and unfunded commitment liability in the amount of $ 4.5 million, or $ 3.4 million, net of tax. Allowance for Credit Losses (ACL) has a direct impact on the provision expense. An increase in the ACL is funded through recoveries and provision expense. The Company segregates its allowance into two reserves: The Allowance for Credit Losses (ACL) and the Allowance for Unfunded Loan Commitments and Letters of Credit (AULC). When combined, these reserves constitute the total Current Expected Credit Losses (CECL). The allowance does not include an accretable yield of $ 3.5 million and $ 4.0 million as of March 31, 2024 and December 31, 2023, respectively, related to the acquisitions of Bank of Geneva in 2019 and Ossian State Bank and Perpetual Federal Savings Bank in 2021 and Peoples Federal Savings and Loan Bank in 2022 as previously discussed in Note 2. The AULC is reported within other liabilities while the ACL portion associated with loans is netted within the loans, net asset line on the condensed consolidated balance sheets. The following tables break down the activity within ACL for each loan portfolio classification and shows the contribution provided by both the recoveries and the provision along with the reduction of the allowance caused by charge-offs for the three months ended March 31, 2024 and March 31, 2023 in addition to the ending balances as of December 31, 2023: (In Thousands) Consumer Agricultural Agricultural Commercial Commercial Consumer Total Three Months Ended March 31, 2024 ALLOWANCE FOR CREDIT LOSSES Beginning balance $ 3,581 $ 312 $ 336 $ 17,400 $ 2,093 $ 1,302 $ 25,024 Provision for credit losses - loans ( 290 ) 859 41 ( 1,450 ) 674 ( 123 ) ( 289 ) Charge-offs ( 10 ) - - - ( 101 ) ( 81 ) ( 192 ) Recoveries 4 - - 3 66 64 137 Ending Balance $ 3,285 $ 1,171 $ 377 $ 15,953 $ 2,732 $ 1,162 $ 24,680 (In Thousands) Consumer Agricultural Agricultural Commercial Commercial Consumer Total Three Months Ended March 31, 2023 ALLOWANCE FOR CREDIT LOSSES Beginning balance $ 998 $ 349 $ 751 $ 11,924 $ 5,382 $ 909 $ 20,313 Adoption of ASU 2016-13 2,874 ( 166 ) ( 650 ) 3,501 ( 2,165 ) 170 3,564 Provision for credit losses - loans ( 256 ) 26 ( 35 ) 661 191 230 817 Charge-offs - - - - - ( 122 ) ( 122 ) Recoveries 7 - - 2 6 47 62 Ending Balance $ 3,623 $ 209 $ 66 $ 16,088 $ 3,414 $ 1,234 $ 24,634 (In Thousands) Consumer Agricultural Agricultural Commercial Commercial Consumer Total Year Ended December 31, 2023 ALLOWANCE FOR CREDIT LOSSES Beginning balance $ 998 $ 349 $ 751 $ 11,924 $ 5,382 $ 909 $ 20,313 Adoption of ASU 2016-13 2,874 ( 166 ) ( 650 ) 3,501 ( 2,165 ) 170 3,564 Provision for credit losses - loans ( 326 ) 24 225 1,967 ( 643 ) 451 1,698 Charge-offs - - - - ( 565 ) ( 425 ) ( 990 ) Recoveries 35 105 10 8 84 197 439 Ending Balance $ 3,581 $ 312 $ 336 $ 17,400 $ 2,093 $ 1,302 $ 25,024 The following tables break down the activity in the AULC for the three months ended March 31, 2024 and March 31, 2023 in addition to the ending balances as of December 31, 2023: (In Thousands) Unfunded Three Months Ended March 31, 2024 ALLOWANCE FOR UNFUNDED LOAN COMMITMENTS AND LETTERS OF CREDIT Beginning balance $ 2,212 Provision for credit losses - off balance sheet credit exposures ( 266 ) Charge-offs - Recoveries - Ending Balance $ 1,946 (In Thousands) Unfunded Three Months Ended March 31, 2023 ALLOWANCE FOR UNFUNDED LOAN COMMITMENTS AND LETTERS OF CREDIT Beginning balance $ 1,262 Adoption of ASU 2016-13 904 Provision for credit losses - off balance sheet credit exposures 62 Charge-offs - Recoveries - Ending Balance $ 2,228 (In Thousands) Unfunded Year Ended December 31, 2023 ALLOWANCE FOR UNFUNDED LOAN COMMITMENTS AND LETTERS OF CREDIT Beginning balance $ 1,262 Adoption of ASU 2016-13 904 Provision for credit losses - off balance sheet credit exposures 46 Charge-offs - Recoveries - Ending Balance $ 2,212

Servicing	NOTE 6 SERVICING Loans serviced for others are not included in the accompanying Company's consolidated balance sheets. The unpaid principal balances of 1-4 family real estate loans serviced for others were $ 363.6 , $ 370.2 and $ 367.8 million at March 31, 2024 and 2023 and at December 31, 2023, respectively. Unpaid principal balances of agricultural real estate loans serviced for others were $ 133.8 , $ 136.3 and $ 135.8 million at March 31, 2024, 2023 and at December 31, 2023, respectively. The balance of capitalized servicing rights included in assets at March 31, 2024 and December 31, 2023 for 1-4 family real estate loans, was $ 3.4 million and $ 3.5 million, respectively. Agricultural real estate loan servicing rights, established in 2023, were $ 2.1 million and $ 2.2 million at March 31, 2024 and December 31, 2023, respectively. The capitalized addition of servicing rights is included in net gain on sale of loans on the Company's consolidated statement of income. The fair value of the capitalized servicing rights for 1-4 family real estate loans as of March 31, 2024 and 2023 was $ 5.5 million and $ 5.8 million, respectively, and at December 31, 2023 was $ 5.5 million. Capitalized servicing rights for agricultural real estate loans had a fair value of $ 2.1 million and $ 1.5 million as of March 31, 2024 and 2023, respectively, and was $ 2.2 million at December 31, 2023. As the Company continues to refine and enhance its process for valuing agricultural real estate loan servicing rights, it may be necessary to adjust their value in future periods. The valuations were completed by stratifying the loans into like groups based on loan type and term. Impairment was measured by estimating the fair value of each stratum, taking into consideration an estimated level of prepayment based upon current market conditions. An average constant prepayment rate for 1-4 family real estate loans of 5.4 % and 5.7 % were utilized at March 31, 2024 and 2023, respectively, and 6.3 % at December 31, 2023. At March 31, 2024, two 1-4 family real estate strata, which included 92 of the total 3,705 loans, were slightly below the carrying value using a discount yield of 6.22 % which resulted in the need to establish a $ 2 thousand valuation allowance. The carrying value of eleven agricultural real estate strata, which included 38 of the total 588 loans, using an approximate discount rate of 9.17 % were lower than market value requiring a $ 5 thousand valuation allowance to be established.

Earnings Per Share

Earnings Per Share [Abstract]
Earnings Per Share	NOTE 7 EARNINGS PER SHARE Basic earnings per share are calculated using the two-class method. The two-class method is an earnings allocation formula under which earnings per share is calculated from common stock and participating securities according to dividends declared and participation rights in undistributed earnings. Under this method, all earnings distributed and undistributed, are allocated to participating securities and common shares based on their respective rights to receive dividends. Unvested share-based payment awards that contain non-forfeitable rights to dividends are considered participating securities (i.e. unvested restricted stock), not subject to performance based measures. Basic earnings per share is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding. Application of the two-class method for participating securities results in a more dilutive basic earnings per share as the participating securities are allocated the same amount of income as if they are outstanding for purposes of basic earnings per share. There is no additional potential dilution in calculating diluted earnings per share, therefore basic and diluted earnings per share are the same amounts. Other than the restricted stock plan, the Company has no other employee stock based compensation plans. The Compensation Committee of the Company has determined that it is appropriate to award shares of the common stock of the Company to Outside Directors and Employees that are officers of the Company or the Bank who also serve as Directors of the Company and the Bank as a portion of their retainer for services rendered as Directors of the Company and the Bank. The Committee believes that it is appropriate to award the Directors shares equal to a specific dollar amount, rounded to the nearest whole share on an annual basis commencing on June 5, 2020 and thereafter on the first Friday of June in each year. Directors receive a prorated dollar value of shares for a partial year of service. The value for the shares is to be based upon the closing price for shares on June 4, 2020 and thereafter on the first Thursday in June in each year. On June 2, 2023, twelve Directors each received $ 14,997 which equated to 754 shares. The use of stock for Directors’ retainer, does not have an effect on diluted earnings per share as it is immediately vested. Any stock awards to senior management are made in March with other members of management receiving any awards in August. On March 1, 2024, senior management received stock awards of 23,369 shares worth $ 472,054 . On March 1, 2023, senior management received stock awards of 21,700 shares worth $ 562,030 while other members of management received stock awards of 41,225 shares worth $ 844,018 during third quarter 2023.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	NOTE 8 DERIVATIVE FINANCIAL INSTRUMENTS The Bank uses derivative financial instruments to help manage exposure to interest rate risk and the effects that changes in interest rates may have on net income and the fair value of assets and liabilities. The Bank enters into interest rate swap agreements as part of its asset/liability management strategy to help manage its interest rate risk position. The Bank entered into three pay-fixed receive variable interest rate swap transactions, with a combined notional value of $ 100 million, designated and qualifying as accounting hedges during the last quarter of 2023. Designating an interest rate swap as an accounting hedge allows the Company to recognize gains and losses, less any ineffectiveness, in the Company's consolidated statement of income within the same period that the hedged item affects earnings. The Company includes the gain or loss on the hedged items in the same line item as the offsetting loss or gain on the related interest rate swaps. The fair value of interest rate swaps with a positive fair value are reported in other assets in the Company's consolidated balance sheets while interest rate swaps with a negative fair value are reported in accrued expenses and other liabilities in the Company's consolidated balance sheets.

Investments in Affordable Housing Projects [Abstract]
Qualified Affordable Housing Project Investments	NOTE 9 QUALIFIED AFFORDABLE HOUSING PROJECT INVESTMENTS The Company invests in certain qualified affordable housing projects. The Company has elected to account for its investment in qualified affordable housing projects using the proportional amortization method described in FASB ASU 2014-01, "Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Low-Income housing Tax Credit Projects (A Consensus of the FASB Emerging Issues Task Force)", which was updated in March 2023 and released as FASB ASU 2023-02. Under the proportional amortization method, an investor amortizes the initial cost of the investment to income tax expense in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense. At March 31, 2024, the balance of the Company's investments in qualified affordable housing projects was $ 3.9 million. This balance is reflected in the Other assets line on the condensed consolidated balance sheets. The unfunded commitments related to the investments in qualified affordable housing projects totaled $ 1.4 million at March 31, 2024. This balance is reflected in the accrued expense and other liabilities line on the condensed consolidated balance sheets. The funded balance in qualified affordable housing projects was $ 2.4 million out of a total of $ 4.0 million committed at December 31, 2023. During the three months ended March 31, 2024, the Company recognized amortization expense with respect to its investments in qualified affordable housing projects of $ 110 thousand, partially offset by tax credits and other benefits from its investments in affordable housing tax credits of $ 108 thousand. During the three month period ended March 31, 2024, the Company did no t incur any impairment losses related to its investments in qualified affordable housing projects.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	NOTE 10 FAIR VALUE OF FINANCIAL INSTRUMENTS Fair values of financial instruments are management's estimate of the values at which the instruments could be exchanged in a transaction between willing parties. These estimates are subjective and may vary significantly from amounts that would be realized in actual transactions. In addition, other significant assets are not considered financial assets including deferred tax assets, premises, equipment and intangibles. Further, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on the fair value estimates and have not been considered in any of the estimates. Fair Value Measurements: In general, fair values determined by Level 1 inputs use quoted prices in active markets for identical assets or liabilities in active markets that the Company has the ability to access. Available-for-sale securities, when quoted prices are available in an active market, securities are valued using the quoted price and are classified as Level 1. Fair values determined by Level 2 inputs use other inputs that are observable, either directly or indirectly. These Level 2 inputs include quoted prices for similar assets and liabilities in active markets, and other inputs such as interest rates and yield curves that are observable at commonly quoted intervals. Available-for-sale securities classified as Level 2 are valued using the prices obtained from an independent pricing service. The prices are not adjusted. Securities of obligations of state and political subdivisions are valued using a type of matrix, or grid, pricing in which securities are benchmarked against the treasury rate based on credit rating. Substantially all assumptions used by the independent pricing service are observable in the marketplace, can be derived from observable data, or are supported by observable levels at which transactions are executed in the marketplace. Level 3 inputs are unobservable inputs, including inputs that are available in situations where there is little, if any, market activity for the related asset or liability. The Bank holds some local municipals that the Bank evaluates based on the credit strength of the underlying project. The fair value is determined by valuing similar credit payment streams at similar rates. In instances where inputs used to measure fair value fall into different levels in the above fair value hierarchy, fair value measurements in their entirety are categorized based on the lowest level input that is significant to the valuation. The Company's assessment of the significance of particular inputs to these fair value measurements requires judgment and considers factors specific to each asset. The following summarizes financial assets measured at fair value on a recurring basis as of March 31, 2024 and December 31, 2023, segregated by level or the valuation inputs within the fair value hierarchy utilized to measure fair value: Assets and Liabilities Measured at Fair Value on a Recurring Basis (In Thousands) March 31, 2024 Quoted Prices in Significant Significant Assets - (Securities Available-for-Sale) U.S. Treasury $ 74,693 $ - $ - U.S. Government agencies 19,525 108,213 - Mortgage-backed securities - 78,404 - State and local governments - 64,886 1,795 Total Securities Available-for-Sale $ 94,218 $ 251,503 $ 1,795 (In Thousands) December 31, 2023 Quoted Prices in Significant Significant Assets - (Securities Available-for-Sale) U.S. Treasury $ 80,270 $ - $ - U.S. Government agencies 19,630 108,592 - Mortgage-backed securities - 82,132 - State and local governments - 65,394 2,460 Total Securities Available-for-Sale $ 99,900 $ 256,118 $ 2,460 The following tables represent the changes in the Level 3 fair-value category of which unobservable inputs are relied upon as of the three periods ended March 31, 2024 and March 31, 2023.

The Company also has assets that, under certain conditions, are subject to measurement at fair value on a non-recurring basis. At March 31, 2024 and December 31, 2023, such assets consist primarily of collateral dependent loans. Collateral dependent loans categorized as Level 3 assets consist of non-homogeneous loans that have expected credit losses. The Company estimates the fair value of the loans based on the present value of expected future cash flows using management's best estimate of key assumptions. These assumptions include future payment ability, timing of payment streams, and estimated realizable values of available collateral (typically based on outside appraisals.) At March 31, 2024 and December 31, 2023 , fair value of collateral dependent loans categorized as Level 3 was $ 18.8 million and $ 22.7 million, respectively. During 2023, impairment was recognized on loan servicing rights based upon the independent third party's quarterly valuation. A valuation allowance was established by strata to quantify the likely impairment of the value of the loan servicing rights to the Company. If the carrying amount of an individual strata exceeds the fair value, impairment was recorded on that strata so the servicing asset was carried at fair value. Impairment was $ 7 thousand at December 31, 2023. The following table presents assets measured at fair value on a nonrecurring basis at March 31, 2024 and December 31, 2023: (In Thousands) Assets Measured at Fair Value on a Nonrecurring Basis at March 31, 2024 Balance at Quoted Prices Significant Significant Collateral dependent $ 18,849 $ - $ - $ 18,849 Loan servicing rights 54 - - 54 (In Thousands) Assets Measured at Fair Value on a Nonrecurring Basis at December 31, 2023 Balance at Quoted Prices Significant Significant Collateral dependent $ 22,676 $ - $ - $ 22,676 Loan servicing rights 58 - - 58 The following table presents quantitative information about unobservable inputs used in recurring and nonrecurring Level 3 fair value measurements: (In Thousands) Range Fair Value at (Weighted March 31, 2024 Valuation Technique Unobservable Inputs Average) State and local government $ 1,795 Discounted Cash Flow Credit strength of underlying project discount rate 3.47 - 4.80 % 4.49 %) Collateral dependent 18,849 Collateral based Discount to reflect current market 0.00 - 50.00 % 33.79 %) Loan servicing rights 54 Discounted Cash Flow Constant prepayment rate and discount rate 7.64 - 22.80 % 11.86 %) (In Thousands) Range Fair Value at (Weighted December 31, 2023 Valuation Technique Unobservable Inputs Average) State and local government $ 2,460 Discounted Cash Flow Credit strength of underlying project discount rate - 0.17 - 4.92 % 3.49 %) Collateral dependent 22,676 Collateral based Discount to reflect current market 0.00 - 50.00 % 0.41 %) Loan servicing rights 58 Discounted Cash Flow Constant prepayment rate and 5.11 - 22.80 % 10.87 %) The estimated fair values, and related carrying or notional amounts, for on and off-balance sheet financial instruments as of March 31, 2024 and December 31, 2023 are reflected below.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	NOTE 13 RECENT ACCOUNTING PRONOUNCEMENTS In March 2022, the Sixth Circuit issued a ruling in CIC Services LLC v IRS vacating a previously referenced IRS Notice 2016-66. That ruling, as it stood, would remove the requirement of disclosure on Form 8886. However, on April 10, 2023, the IRS issued IR-2023-74 proposing regulations that classify Sec. 831(b) captives with less than a 65 % claims loss ratio over a 10-year period as a "listed transaction." This provision would apply to only captives that have been in existence for at least 10 years. This is a change from Notice 2016-66 which classified Sec. 831(b) captives with less than a 70 % claims loss ratio as a "transaction of interest." Final regulations are expected to be issued in Q1 2024. Management and its advisors are in the process of evaluating the impact of these proposed regulations. The Company dissolved its Captive insurance company, F&M Risk Management, in December 2023. In March 2023, the FASB issued ASU 2023-02 "Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (a Consensus of the Emerging Issues Task Force)." The amendments in this Update expands the use of the proportional amortization method of accounting to equity investments in tax credit programs beyond those in low-income-housing tax credit (LIHTC) programs. The ASU allows entities to elect the proportional amortization method, on a tax-credit-program-by-tax-credit-program basis, for all equity investments in tax credit programs meeting the eligibility criteria in Accounting Standards Codification (ASC) 323-74-25-1. While the ASU does not significantly alter the existing eligibility criteria, it does address existing interpretive issues. It also prescribes specific information reporting entities must disclose about tax credit investments each period. The ASU is effective for reporting periods beginning after December 15, 2023, for public business entities. Early adoption is permitted. Entities have the option of applying the ASU using either a modified retrospective or retrospective adoption approach. For some changes related to existing LIHTC investments, prospective application is permitted. The Company adopted ASU 2023-02 effective January 1, 2024 using the prospective approach. The financial impact was immaterial to the financial statements. In October 2023, the FASB issued ASU 2023-06 "Disclosure Improvements - Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative." The amendments in this Update are the result of the FASB’s decision to incorporate into the Accounting Standards Codification certain disclosure requirements, referred by the SEC, that require incremental information to US GAAP. Topics in the ASU that have applicability to the Company are as follows: * Statement of Cash Flows - requires an accounting policy disclosure in annual periods of where cash flows associated with derivative instruments and their related gains and losses are presented in the statement of cash flows. * Debt - requires disclosure of amounts and terms of unused lines of credit and unfunded commitments and the weighted-average interest rate on outstanding short-term borrowings. * Derivatives and Hedging - adds cross-reference to disclosure requirements related to where cash flows associated with derivative instruments and their related gains and losses are presented in the statement of cash flows. The effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. If by June 30, 2027, the SEC has not removed the applicable requirement from Regulation S-X or Regulation S-K, the pending content of the related amendment will be removed from the Accounting Standards Codification and will not become effective for any entity. Management is reviewing the provisions of ASU 2023-06, and does not expect the adoption of the ASU to have a material effect on the Company’s financial statements. In November 2023, the FASB issued ASU 2023-07 " Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures." The amendments in this Update improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in this Update primarily require that a public entity disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker; require that a public entity disclose the title and position of the chief operating decision maker and an explanation of how the chief operating decision maker uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources; require that a public entity that has a single reportable segment provide all the disclosures required by the amendments in this Update and all existing segment disclosures in Topic 280. The amendments in this Update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. A public entity should apply the amendments in this Update retrospectively to all prior periods presented in the financial statements. Management is evaluating the Update and does not expect adoption of the Update to have a material effect on the Company’s financial position or results of operations. In December 2023, the FASB issued ASU 2023-09 "Income Taxes (Topic 740) - Improvements to Income Tax Disclosures." The amendments in this Update require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income [or loss] by the applicable statutory income tax rate). The amendments also require disclosure of the amount of income taxes paid (net of refunds received) disaggregated by federal (national) and state jurisdictions. For public business entities, the amendments in this Update are effective for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The amendments in this Update should be applied on a prospective basis and retrospective application is permitted. Management is evaluating the Update and does not expect adoption of the Update to have a material effect on the Company’s financial position or results of operations.
