Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation and Other	NOTE 1 BASIS OF PRESENTATION AND OTHER The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions for Form 10Q and Rule 10-01 of Regulation S-X; accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation have been included. Share data has been adjusted to reflect a 2-for-1 stock split on September 20, 2017. Operating results for the nine months ended September 30, 2018 are not necessarily indicative of the results that are expected for the year ended December 31, 2018. The condensed consolidated balance sheet of the Company as of December 31, 2017, 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 Company's Annual Report on Form 10-K for the year ended December 31, 2017. The Company recognizes revenues as they are earned based on contractual terms, as transactions occur, or as services are provided and collectability is reasonably assured. 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. 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.

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 September 30, 2018 and December 31, 2017, follows: (In Thousands) September 30, 2018 Amortized Gross Unrealized Gross Unrealized Fair Cost Gains Losses Value Available-for-Sale: U.S. Treasury $ 21,141 $ - $ (370 ) $ 20,771 U.S. Government agencies 78,753 - (2,986 ) 75,767 Mortgage-backed securities 36,350 11 (1,761 ) 34,600 State and local governments 53,040 199 (1,302 ) 51,937 Total available-for-sale securities $ 189,284 $ 210 $ (6,419 ) $ 183,075 (In Thousands) December 31, 2017 Amortized Gross Unrealized Gross Unrealized Fair Cost Gains Losses Value Available-for-Sale: U.S. Treasury $ 21,219 $ - $ (241 ) $ 20,978 U.S. Government agencies 82,198 - (1,732 ) 80,466 Mortgage-backed securities 40,236 64 (790 ) 39,510 State and local governments 55,512 437 (505 ) 55,444 Total available-for-sale securities $ 199,165 $ 501 $ (3,268 ) $ 196,398 Investment securities will at times depreciate to an unrealized loss position. The Company utilizes the following criteria to assess whether impairment is other than temporary. No one item by itself will necessarily signal that a security should be recognized as an other than temporary impairment. 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. The underwater security has longer than 10 years to maturity and the loss position had existed for more than 3 years. 5. 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 impairment is judged to be other than temporary, the cost basis of the individual security shall be written down to fair value, thereby establishing a new cost basis. The new cost basis shall not be changed for subsequent recoveries in fair value. The amount of the write down shall be included in current earnings as a realized loss. The recovery in fair value, if any, shall be recognized in earnings when the security is sold. The table below is presented by category of security and length of time in a continuous loss position. The Company currently does not hold any securities with other than temporary impairment. Information pertaining to securities with gross unrealized losses at September 30, 2018 and December 31, 2017, aggregated by investment category and length of time that individual securities have been in a continuous loss position follows: (In Thousands) September 30, 2018 Less Than Twelve Months Twelve Months & Over Gross Unrealized Fair Gross Unrealized Fair Losses Value Losses Value U.S. Treasury $ (111 ) $ 6,860 $ (259 ) $ 13,910 U.S. Government agencies (166 ) 7,424 (2,820 ) 68,344 Mortgage-backed securities (132 ) 7,220 (1,629 ) 26,657 State and local governments (350 ) 23,413 (952 ) 20,371 Total available-for-sale securities $ (759 ) $ 44,917 $ (5,660 ) $ 129,282 (In Thousands) December 31, 2017 Less Than Twelve Months Twelve Months & Over Gross Unrealized Fair Gross Unrealized Fair Losses Value Losses Value U.S. Treasury $ (36 ) $ 6,924 $ (205 ) $ 14,054 U.S. Government agencies (314 ) 27,328 (1,418 ) 53,139 Mortgage-backed securities (70 ) 7,149 (720 ) 28,080 State and local governments (205 ) 24,999 (300 ) 11,567 Total available-for-sale securities $ (625 ) $ 66,400 $ (2,643 ) $ 106,840 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 rate changes, and the Company has the intent and ability to hold the securities for the foreseeable future. Additionally, the decline in value is primarily due to changes in interest rates since the securities were purchased. 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 and nine months ended September 30, 2018 and September 30, 2017. Three Months Nine Months (In Thousands) (In Thousands) 2018 2017 2018 2017 Gross realized gains $ 51 $ - $ 51 $ 58 Gross realized losses (41 ) - (41 ) (11 ) Net realized gains $ 10 $ - $ 10 $ 47 Tax expense related to net realized gains $ 2 $ - $ 2 $ 16 The net realized gains on sales and related tax expense is a reclassification out of accumulated other comprehensive income (loss). The net realized gain is included in net gain on sale of available-for-sale securities and the related tax expense is included in income taxes in the condensed consolidated statements of income and comprehensive income. The amortized cost and fair value of debt securities at September 30, 2018, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

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. Industrial Development Bonds (IDB): Funds for public improvements in the Bank’s service area. Repayment ability is based on the continuance of the taxation revenue as the source of repayment. 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 others. 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 Risk Management Association 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 grade is summarized by high liquidity, minimum risk, strong ratios, and low handling costs. 3. Two (2) Good. Desirable loans of somewhat less stature than Grade 1, but with strong financial statements. Loan supported by financial statements containing strong balance sheets, generally with a leverage position less than 1.50, 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. Generally, customers should have a leverage position less than 2.00. May be some weakness but with offsetting features of other support readily available. Loans that are meeting the terms of repayment. Loans may be graded 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 are observed, a lower risk grade is warranted. 5. Four (4) Satisfactory / Monitored. A “4” (Satisfactory/Monitored) risk grade 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 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 and 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 but 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, 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 Bank had approximately $98 thousand of its impaired loans classified as troubled debt restructured (TDR) as of September 30, 2018, $534 thousand as of December 31, 2017 and $540 thousand as of September 30, 2017. During the year to date 2018 and 2017, there were no new loans considered TDR. For the three and nine month period ended September 30, 2018 and 2017, there were no TDRs that subsequently defaulted after modification. For the nine month period ended September 30, 2018, $418 thousand of impaired loans classified as TDR involving one relationship was paid off. For the majority of the Bank’s impaired loans, the Bank will apply the fair value of collateral or use 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 an impaired loan are periodically evaluated. Maximum time of re-evaluation is every 12 months for chattels and titled vehicles and every two years for real estate. In this process, third party evaluations are obtained. Until such time that updated appraisals are received, the Bank may discount the collateral value used. The Bank uses 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 is realized when unsecured consumer loans, credit card credits and overdraft lines of credit reach 90 days delinquency. At 120 days delinquent, secured consumer loans are charged down to the value of the collateral, if repossession of the collateral is assured and/or in the process of repossession. Consumer mortgage loan deficiencies are charged down upon the sale of the collateral or sooner upon the recognition of collateral deficiency. Commercial and agricultural credits are charged down at 120 days delinquency, unless an established and approved work-out plan is in place or litigation of the credit will likely result in recovery of the loan balance. Upon notification of bankruptcy, unsecured debt is charged off. Additional charge-off may be realized as further unsecured positions are recognized. The following tables present loans individually evaluated for impairment by class of loans for three months ended September 30, 2018 and September 30, 2017.

Earnings Per Share [Abstract]
Earnings Per Share	NOTE 5 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 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 stock based compensation plans.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	NOTE 6 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. The following assumptions and methods were used in estimating the fair value for financial instruments: Cash and Cash Equivalents The carrying amounts reported in the balance sheet for cash, cash equivalents and federal funds sold approximate their fair values. Also included in this line item are the carrying amounts of interest-bearing deposits maturing within ninety days which approximate their fair values. Fair values of other interest-bearing deposits are estimated using discounted cash flow analyses based on current rates for similar types of deposits. Interest Bearing Time Deposits Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow analysis that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits. Securities – Available-for-sale Fair values for securities, excluding Federal Home Loan Bank and Farmer Mac stock, are based on quoted market price, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments. Other Securities The carrying value of Federal Home Loan Bank and Farmer Mac stock, listed as "other securities", approximates fair value based on the respective redemption provisions. Loans Held for Sale The carrying amount approximates fair value due to insignificant amount of time between origination and date of sale. Loans, net The fair values of the loans are estimated using a credit mark adjustment along with discounted cash flow analysis, using interest rates currently being offered for loans with similar terms to borrowers with similar credit quality. The credit mark adjustment was estimated using merger and acquisition analysis of nationwide bank and thrift deals. Deposits The fair values disclosed for deposits with no defined maturities are equal to their carrying amounts, which represent the amount payable on demand. The carrying amounts for variable-rate, fixed term money market accounts and certificates of deposit approximate their fair value at the reporting date. Fair value for fixed-rate certificates of deposit are estimated using a discounted cash flow analysis that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits. Federal Funds Purchased and Securities Sold Under Agreements to Repurchase The carrying value of federal funds purchased and securities sold under agreements to repurchase approximates fair values. FHLB Advances Fair values or FHLB advances are estimated using discounted cash flow analysis based on the Company’s current incremental borrowing rates for similar types or borrowing arrangements. Accrued Interest Receivable and Payable The carrying amounts of accrued interest approximate their fair values. Off Balance Sheet Financial Instruments Fair values for off-balance sheet, credit related financial instruments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counter-parties' credit standing. The estimated fair values, and related carrying or notional amounts, for on and off-balance sheet financial instruments as of September 30, 2018 and December 31, 2017 are reflected below.

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 September 30, 2018 and December 31, 2017, 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) September 30, 2018 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Observable Inputs (Level 2) Significant Observable Inputs (Level 3) Assets - (Securities Available-for-Sale) U.S. Treasury $ 20,771 $ - $ - U.S. Government agencies - 75,767 - Mortgage-backed securities - 34,600 - State and local governments - 50,544 1,393 Total Securities Available-for-Sale $ 20,771 $ 160,911 $ 1,393 December 31, 2017 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Observable Inputs (Level 2) Significant Observable Inputs (Level 3) Assets - (Securities Available-for-Sale) U.S. Treasury $ 20,978 $ - $ - U.S. Government agencies - 80,466 - Mortgage-backed securities - 39,510 - State and local governments - 54,016 1,428 Total Securities Available-for-Sale $ 20,978 $ 173,992 $ 1,428 The following table represents the changes in the Level 3 fair-value category of which unobservable inputs are relied upon as of September 30, 2018 and September 30, 2017.

The Company also has assets that, under certain conditions, are subject to measurement at fair value on a non-recurring basis. At September 30, 2018 and December 31, 2017, such assets consist primarily of collateral dependent impaired loans. Collateral dependent impaired loans categorized as Level 3 assets consist of non-homogeneous loans that are considered impaired. 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 September 30, 2018 and December 31, 2017, fair value of collateral dependent impaired loans categorized as Level 3 was $822 and $508 thousand, respectively. The specific allocation for impaired loans was $148 and $106 thousand as of September 30, 2018 and December 31, 2017, respectively, which are accounted for in the allowance for loan losses (see Note 4). Other real estate is reported at either the lower of the fair value of the real estate minus the estimated costs to sell the asset or the cost of the asset. The determination of fair value of the real estate relies primarily on appraisals from third parties. If the fair value of the real estate, minus the estimated costs to sell the asset, is less than the asset's cost, the deficiency is recognized as a valuation allowance against the asset through a charge to expense. The valuation allowance is therefore increased or decreased, through charges or credits to expense, for changes in the asset's fair value or estimated selling costs.
