Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1 - Summary of Significant Accounting Policies Nature of Operations The Farmers & Merchants Bancorp, Inc. (the Company) through its bank subsidiary, The Farmers & Merchants State Bank (the Bank) provides a variety of financial services to individuals and small businesses through its offices in Northwest Ohio and Northeast Indiana. Consolidation Policy The consolidated financial statements include the accounts of Farmers & Merchants Bancorp, Inc. and its wholly-owned subsidiaries, The Farmers & Merchants State Bank (the Bank), a commercial banking institution and Farmers & Merchants Risk Management, Inc. (the Captive), a Captive insurance company. All significant inter-company balances and transactions have been eliminated. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses and the valuation of mortgage servicing rights. Actual results could differ from those estimates. The determination of the adequacy of the allowance for loan losses is based on estimates that are particularly susceptible to significant changes in the economic environment and market conditions. In connection with the determination of the estimated losses on loans, management obtains independent appraisals for significant collateral. The Bank’s loans are generally secured by specific items of collateral including real property, consumer assets, and business assets. Although the Bank has a diversified loan portfolio, a substantial portion of its debtors’ ability to honor their contracts is dependent on local economic conditions in the agricultural industry. While management uses available information to recognize losses on loans, further reductions in the carrying amounts of loans may be necessary based on changes in local economic conditions. In addition regulatory agencies, as an integral part of their examination process, periodically review the estimated losses on loans. Such agencies may require the Bank to recognize additional losses based on their judgments about information available to them at the time of their examination. Because of these factors, it is reasonably possible that the estimated losses on loans may change materially in the near term. However, the amount of the change that is reasonably possible cannot be estimated. Cash and Cash Equivalents For purposes of the consolidated statement of cash flows, the Company considers all highly liquid debt instruments purchased with an original maturity of three months or less to be cash equivalents. This includes cash on hand, amounts due from banks, and federal funds sold. Generally, federal funds are purchased for one day periods. Restrictions on Cash and Amounts Due from Banks The Bank is required to maintain average balances on hand with the Federal Reserve Bank. The aggregate reserve was $12.6 million for December 31, 2018 and it was $11.4 million for December 31, 2017. The Company and its subsidiaries maintain cash balances with high quality credit institutions. At times such balances may be in excess of the federally insured limits. Securities Debt securities are classified as available-for-sale. Securities available-for-sale are carried at fair value with unrealized gains and losses reported in other comprehensive income (loss). Net realized gains and losses on securities available for sale are included in noninterest income and, when applicable, are reported as a reclassification adjustment, net of tax, in other comprehensive income (loss). Gains and losses on sales of securities are determined on the specific-identification method. Declines in the fair value of securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses. In estimating other-than-temporary impairment losses, management considers (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. The related write-downs are included in earnings as realized losses. Other Securities Other Securities is the Federal Home Loan Bank of Cincinnati stock which is held to enable the Bank to conduct business with the entity. The Federal Home Loan Bank sells and purchases their stock at par. The Federal Home Loan Bank of Cincinnati stock is carried at cost and held as collateral security for all indebtedness of the Bank to the Federal Home Loan Bank. The Federal Home Loan Bank of Cincinnati is evaluated for impairment as conditions warrant. Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are reported at the amount of unpaid principal, reduced by unearned discounts and deferred loan fees and costs, as well as, by the allowance for loan losses. Interest income is accrued on a daily basis based on the principal outstanding. Generally, a loan is classified as nonaccrual and the accrual of interest income is generally discontinued when a loan becomes ninety days past due as to principal or interest and these loans are placed on a “cash basis” for purposes of income recognition. Management may elect to continue the accrual of interest when the estimated net realizable value of collateral is sufficient to cover the principal and accrued interest, and the loan is in the process of collection. When a loan is placed on nonaccrual status, all previously accrued and unpaid interest receivable is charged against income. Loan origination and commitment fees and certain direct loan origination costs are deferred and amortized as a net adjustment to the related loan’s yield. The Bank is generally amortizing these costs over the contractual life of such loans. Allowance for Loan Losses The allowance for loan losses is established through a provision for loan losses charged to income. Loans deemed to be uncollectable and changes in the allowance relating to loans are charged against the allowance for loan losses, and subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based on management’s periodic review of the collectability of the loans in light of historical experiences, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective, as it requires estimates that are subject to revision as more information becomes available. The allowance consists of specific, general and unallocated components. The specific component relates to loans that are classified as doubtful, substandard or special mention. For such loans that are also classified as impaired, an allowance is established when the discounted cash flows (or collateral value) of the impaired loan is lower than the carrying value of that loan. The general component covers non-classified loans and is based on historical loss experience adjusted for qualitative factors. The unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including length of the delay, the reasons for the delay, the borrower's prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan by loan basis for commercial and agricultural loans by either the present value of expected future cash flows discounted at the loan's effective interest rate or the fair value of the collateral if the loan is collateral dependent. At 90 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. 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. Large groups of homogeneous loans are collectively evaluated for impairment. Accordingly, the Bank does not separately identify individual consumer loans for impairment, unless such loans are the subject of a restructuring agreement due to financial difficulties of the borrower. For more information regarding the actual composition and classification of loans involved in the establishment of the allowance for loan loss, please see Note 4 provided here with the notes to consolidated financial statements. Loans Held for Sale Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value in the aggregate. Net unrealized losses, if any, are recognized in a valuation allowance by charges to income. Servicing Assets Servicing assets are recognized as separate assets when rights are acquired through purchase or sale of financial assets. Capitalized servicing rights are amortized into noninterest expense in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets. Servicing assets are evaluated for impairment based upon the fair value of the rights as compared to amortized cost. Impairment is determined by stratifying rights by predominant characteristics, such as interest rates and terms. Fair value is determined using prices for similar assets with similar characteristics, when available, or based upon discounted cash flows using market based assumptions. Impairment is recognized through a valuation allowance for an individual stratum, to the extent that fair value is less than the capitalized amount for the stratum. Fees received for servicing loans owned by investors are based on a percentage of the outstanding monthly principal balance of such loans and are included in operating income as loan payments are received. Costs of servicing loans are charged to expense as incurred. Goodwill and Other Intangible Assets Goodwill results from business acquisitions and represents the excess of the purchase price over the fair value of acquired tangible assets and liabilities and identifiable intangible assets. Goodwill is assessed at least annually. If possible impairment is likely, the Bank will utilize the assistance of an independent third party for impairment and any such impairment is recognized in the period identified. Periodically the Bank will have an independent third party assess the possibility of impairment of Goodwill. Such an assessment was performed as of September 30, 2017. The goodwill impairment analysis consisted of a first step goodwill impairment test which was used to identify potential impairment by comparing the fair value of the relevant reporting unity with its carrying value, including goodwill. The analysis was performed under guidance of FASB ASC 350. The engagement would have expanded to the second step goodwill impairment valuation if necessary; however, the findings showed the second step was not warranted. The analysis confirmed no impairment was likely. In quantitative testing done in 2018, the excess fair value of capital was $58.5 million or 51.1% over the carrying value and was over fourteen times the value of the goodwill being carried Therefore, the Bank concluded it is unlikely impairment of Goodwill has occurred from the goodwill established from the Bank’s acquisition which occurred on December 31, 2007. Other intangible assets consist of core deposit intangible assets arising from business acquisitions. They are initially measured at fair value and then are amortized on a straight line method over their estimated useful lives and evaluated for impairment. These assets are included in other assets on the consolidated balance sheets. Off Balance Sheet Instruments In the ordinary course of business, the Bank has entered into commitments to extend credit, including commitments under credit card arrangements, commercial letters of credit and standby letters of credit. Such financial instruments are recorded when they are funded. Foreclosed Real Estate Foreclosed real estate held for sale is carried at the lower of fair value minus estimated costs to sell, or cost. Costs of holding foreclosed real estate are charged to expense in the current period, except for significant property improvements, which are capitalized. Valuations are periodically performed by management and an allowance is established by a charge to non-interest expense if the carrying value exceeds the fair value minus the estimated costs to sell. Foreclosed real estate is classified as other real estate owned. The net loss from operations of foreclosed real estate held for sale is reported in non-interest expense. At December 31, the Bank’s holding of other real estate owned totaled $600 thousand and approximately $674 thousand for 2018 and 2017 Bank Premises and Equipment Land is carried at cost. Bank premises and equipment are stated at cost less accumulated depreciation. Depreciation is based on the estimated useful lives of the various properties and is computed using straight line and accelerated methods. Costs for maintenance and repairs are charged to operations as incurred. Gains and losses on dispositions are included in current operations. Revenue Recognition Accounting Standards Codification 606, “Revenue from Contracts with Customer” (ASC 606) provides that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Revenue generated from financial instruments, including loans and investment securities, are not included within the scope of ASC 606. The adoption of ASC 606 did not result in a change to the accounting for any of the Company’s revenue streams that are within scope of the amendments. Revenue-generating activities that are within the scope of ASC 606 that are presented as non-interest income in the Company’s consolidated statements of income include: o Customer service fees – these include miscellaneous service fees and transaction-based fees charged for certain services, such as debit card or credit card. Revenue is recognized when the performance obligation is completed, which is generally after a transaction is completed or monthly for account maintenance services. o Other service charges and fees – these include service fees charged for deposit account maintenance and activity along with transaction-based fees charged for certain services, such as overdraft activities, returned check charges and wire transfers. Revenue is recognized when the performance obligation is completed, which is generally after a transaction is completed or monthly for account maintenance services. Federal Income Tax The Company’s income tax expense consists of the following components: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management’s judgment. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits in tax expense. Based on management’s analysis, the Company did not have any uncertain tax positions as of December 31, 2018 and 2017 Earnings Per Share Basic earnings per share represent income available to common stockholders divided by the weighted-average number of common shares outstanding during the period. On August 18, 2017, the Company’s Board of Directors authorized a two-for-one stock split payable on September 20, 2017, for shareholders of record on September 5, 2017. See Note 12 for additional information. Stock-Based Compensation The fair value of restricted common stock is their fair market value on the date of grant. The fair value of restricted stock is amortized as compensation expense on a straight-line basis over the vesting period of the grants. Compensation expense recognized is included in salaries and wages in the consolidated statements of income. Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Corporation – put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets and (3) the Corporation does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets. Treasury Stock Common stock shares repurchased are recorded at market value on date of purchase. Other Comprehensive Income (Loss) Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale securities, are reported as a separate component of the equity section of the balance sheet. Such items, along with net income, are components of other comprehensive income (loss). The company adopted ASU 2018-02 on January 1, 2018 and elected to reclassify the income tax effects of the Tax Cuts and Job Act from AOCI to retained earnings. The reclassification increased retained earnings and decreased AOCI by $359 thousand, with zero net effect on total stockholder’s equity. The components of other comprehensive income (loss) and related tax effects are as follows: (In Thousands) 2018 2017 2016 Net unrealized gain (loss) on available-for-sale securities $ (1,058 ) $ 267 $ (2,721 ) Reclassification adjustment for (gain) loss on sale of available-for-sale securities 9 (47 ) (588 ) Net unrealized gain (loss) on available-for-sale securities (1,049 ) 220 (3,309 ) Tax expense (benefit) (220 ) 74 (1,125 ) Other comprehensive income (loss) $ (829 ) $ 146 $ (2,184 ) Reclassification Certain amounts in the 2017 and 2016 2018 Recent Accounting Pronouncements In May 2014, the FASB issued ASU No. 2014-09 “Revenue from Contracts with Customers (Topic 606) i.e In January 2016, the FASB issued ASU No. 2016-01 “Financial Instruments - Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities.” In February 2016, the FASB issued ASU No. 2016-02 “Leases (Topic 842).” In June Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The ASU is effective for SEC filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019 (i.e., January 1, 2020, for calendar year entities). Early application will be permitted for all organizations for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company has contracted with an external advisor and has formed a committee to determine the methodology to be used. Most importantly, the Company is gathering as much data as possible to enable review scenarios and determine which calculations will produce the most reliable results. The Company is in the early stages of CECL conversion analysis with use of a third party service provider. In November 2016, the FASB issued ASU No. 2016-18 “Statement of Cash Flows (Topic 230) – Restricted Cash.” In January 2017, the FASB issued ASU No. 2017-01 “Business Combinations (Topic 805) – Clarifying the Definition of a Business.” In January 2017, the FASB issued ASU No. 2017-04 “Intangibles – Goodwill and other (Topic 350) – Simplifying the Test for Goodwill Impairment.” In March 2017, the FASB issued ASU No. 2017-08 “Receivables – Nonrefundable Fees and Other Cost (Subtopic 310-20), Premium Amortization on Purchased Callable Debit Securities.” In February 2018, the FASB issued ASU No. 2018-02 “ Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” In March 2018, the FASB issued No. ASU 2018-05 “Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin (SAB) No. 118.” In June 2018, the FASB issued ASU No. 2018-07 “Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting.” These amendments expand the scope of Topic 718, Compensation – Stock Compensation (which currently only includes share-based payments to employees) to include share-based payments issued to nonemployees for goods or services. Consequently, the accounting for share-based payments to nonemployees and employees will be substantially aligned. The ASU supersedes Subtopic 505-50, Equity – Equity-Based Payments to Non-Employees. The guidance is effective for public companies for fiscal years, and interim fiscal periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, but no earlier than a company’s adoption date of Topic 606, Revenue from Contracts with Customers. At this time, the Company has adopted as of December 31, 2018 and does not recognize the existence of any non-employee relationships involving share-based payments. In August 2018, the FASB issued ASU No. 2018-13 “Fair Value Measurement (Topic 820) - Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measuremen

The Bank 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 Bank currently does not hold any securities with other than temporary impairment.

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 others. 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.

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, 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 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. 1. 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. 2. 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. 3. 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. 1. 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. 1. 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.

To determine the 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 and heavily relied upon. 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 down 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.

Federal Income Taxes	Note 10 - Federal Income Taxes The Tax Cuts and Jobs Act was enacted on December 22, 2017. Among other things, the new law (i) establishes a new, flat corporate federal statutory income tax rate of 21%, (ii) eliminates the corporate alternative minimum tax and allows the use of any such carryforwards to offset regular tax liability for any taxable year, (iii) limits the deduction for net interest expense incurred by U.S. corporations, (iv) allows businesses to immediately expense, for tax purposes, the cost of new investments in certain qualified depreciable assets, (v) eliminates or reduces certain deductions related to meals and entertainment expenses, (vi) modifies the limitation on excessive employee remuneration to eliminate the exception for performance-based compensation and clarifies the definition of a covered employee and (vii) limits the deductibility of deposit insurance premiums. The Tax Cuts and Jobs Act also significantly changes U.S. tax law related to foreign operations, however, such changes do not currently impact us. As stated above, as a result of the enactment of the Tax Cuts and Jobs Act on December 22, 2017, we remeasured our deferred tax assets and liabilities based upon the newly enacted U.S. statutory federal income tax rate of 21%, which is the tax rate at which these assets and liabilities are expected to reverse in the future. We recognized a net tax benefit related to the remeasurement of our deferred tax assets and liabilities totaling $8 thousand in 2017.

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. The table below presents basic and diluted earnings per share for the years ended December 31, 2018, 2017, and 2016.

Commitments And Contingencies Disclosure [Abstract]
Off Balance Sheet Activities	Note 14 - Off Balance Sheet Activities Credit Related Financial Instruments The Bank is a party to credit related financial instruments with off-balance-sheet risk in the normal course of business to meet the financing need of its customers. These financial instruments include commitments to extend credit, Standby Letters of Credit, and Commercial Letters of Credit. Such commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets. The Bank's exposure to credit loss is represented by the contractual amount of these commitments. The Bank follows the same credit policies in making commitments as it does for on-balance-sheet instruments. The allowance for credit losses as it relates to unfunded loan commitments (AULC) is included under other liabilities. The AULC as of December 31, 2018 and 2017 At December 31, 2018 and 2017 (In Thousands) 2018 2017 Commitments to extend credit $ 267,166 $ 237,774 Credit card arrangements 20,993 20,184 Standby letters of credit 691 791 Commitments to extend credit, credit card arrangements and Standby Letters of Credit all include exposure to some credit loss in the event of nonperformance of the customer. The Bank’s credit policies and procedures for credit commitments and financial guarantees are the same as those for extensions of credit that are recorded in the financial statements. Due to the fact that these instruments have fixed maturity dates, and because many of them expire without being drawn upon, they generally do not present any significant liquidity risk to the Bank. Collateral Requirements To reduce credit risk related to the use of credit-related financial instruments, the Bank might deem it necessary to obtain collateral. The amount and nature of the collateral obtained is based on the Bank's credit evaluation of the customer. Collateral held varies but may include cash, securities, accounts receivable, inventory, property, plant, and real estate. Legal Contingencies Various legal claims also arise from time to time in the normal course of business, which, in the opinion of management, will have no material effect on the Company’s consolidated financial statements.

Minimum Regulatory Capital Requ

Banking And Thrift [Abstract]
Minimum Regulatory Capital Requirements	Note 15 - Minimum Regulatory Capital Requirements The Company (on a consolidated basis) and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company's and Bank's financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Prompt corrective action provisions are not applicable to bank holding companies. The Basel III Capital Rules, a new comprehensive capital framework for U.S. banking organizations, became effective for on January 1, 2015 (subject to a phase-in period for certain provisions). Quantitative measures established by the Basel III Capital Rules to ensure capital adequacy require the maintenance of minimum amounts and ratios (set forth in the table below) of Common Equity Tier 1 capital, Tier 1 capital and Total capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital to adjusted quarterly average assets (as defined). In connection with the adoption of the Basel III Capital Rules, we elected to opt-out of the requirement to include most components of accumulated other comprehensive income in Common Equity Tier 1. Common Equity Tier 1 is reduced by, goodwill and other intangible assets, net of associated deferred tax liabilities, and subject to transition provisions. The Common Equity Tier 1 (beginning in 2015), Tier 1 and Total capital ratios are calculated by dividing the respective capital amounts by risk-weighted assets. Risk-weighted assets are calculated based on regulatory requirements and include total assets, with certain exclusions, allocated by risk weight category, and certain off-balance-sheet items, among other things. The leverage ratio is calculated by dividing Tier 1 capital by adjusted quarterly average total assets, which exclude goodwill and other intangible assets, among other things. When fully phased in on January 1, 2019, the Basel III Capital Rules will require the Bank to maintain (i) a minimum ratio of Common Equity Tier 1 capital to risk-weighted assets of at least 4.5%, plus a 2.5% “capital conservation buffer” (which is added to the 4.5% Common Equity Tier 1 capital ratio as that buffer is phased in, effectively resulting in a minimum ratio of Common Equity Tier 1 capital to risk-weighted assets of at least 7.0% upon full implementation), (ii) a minimum ratio of Tier 1 capital to risk-weighted assets of at least 6.0%, plus the capital conservation buffer (which is added to the 6.0% Tier 1 capital ratio as that buffer is phased in, effectively resulting in a minimum Tier 1 capital ratio of 8.5% upon full implementation), (iii) a minimum ratio of Total capital (that is, Tier 1 plus Tier 2) to risk-weighted assets of at least 8.0%, plus the capital conservation buffer (which is added to the 8.0% total capital ratio as that buffer is phased in, effectively resulting in a minimum total capital ratio of 10.5% upon full implementation) and (iv) a minimum leverage ratio of 4.0%, calculated as the ratio of Tier 1 capital to average quarterly assets. The implementation of the capital conservation buffer began on January 1, 2016 at the 0.625% level and will be phased in over a four-year period (increasing by that amount on each subsequent January 1, until it reaches 2.5% on January 1, 2019). The capital conservation buffer was 1.875% at December 31, 2018. Management believes, as of December 31, 2018 As of December 31, 2018 The following tables present actual and required capital ratios as of December 31, 2018 and December 31, 2017 December 31, 2018 and December 31, 2017.

Equity [Abstract]
Restrictions of Dividends & Inter-company Borrowings	Note 16 - Restrictions of Dividends & Inter-company Borrowings The Bank is restricted as to the amount of dividends that can be paid. Dividends declared by the Bank that exceed the net income for the current year plus retained income for the preceding two years must be approved by federal and state regulatory agencies. Under this formula dividends of $18.3 million may be paid without prior regulatory approval. Regardless of formal regulatory restrictions, the Bank may not pay dividends that would result in its capital levels being reduced below the minimum requirements shown above. Under current Federal Reserve regulations, the Bank is limited as to the amount and type of loans it may make to the Company. These loans are subject to qualifying collateral requirements on which the amount of the loan may be based.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Note 17 - 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. S ecurities – Available-for-sale Fair values for securities, excluding Federal Home Loan Bank 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 stock approximates fair value based on the redemption provisions of the Federal Home Loan Bank. Loans Held for Sale The carrying amount approximates fair value due to insignificant amount of time between origination and date of sale. Loans, net For 2018, 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. For 2017, the fair values used for net variable-rate loans that reprice frequently, and with no significant change in credit risk, fair values are based on carrying values. The fair values of the fixed rate and all other loans are estimated using discounted cash flow analysis, using interest rates currently being offered for loans with similar terms to borrowers with similar credit quality. 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 Agreement to Repurchase The carrying value of Federal Funds purchased and securities sold under agreement 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 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 counterparties' credit standing. The estimated fair values, and related carrying or notional amounts, for on and off-balance sheet financial instruments as of December 31, 2018 and 2017 (In Thousands) December 31, 2018 December 31, 2017 Carrying Fair Carrying Fair Amount Value Level 1 Level 2 Level 3 Amount Value Level 1 Level 2 Level 3 Financial Assets: Cash and cash equivalents $ 38,365 $ 38,365 $ 38,365 $ - $ - $ 34,467 $ 34,467 $ 34,467 $ - $ - Interest-bearing time deposits 4,019 3,954 - 3,954 - 4,018 4,009 - 4,009 - Securities - available-for-sale 168,447 168,447 36,935 130,085 1,427 196,398 196,398 20,978 173,992 1,428 Other securities 3,679 3,679 - - 3,679 3,679 3,679 - - 3,679 Loans held for sale 495 495 - - 495 1,221 1,221 - - 1,221 Loans, net 839,599 823,914 - - 823,914 816,156 819,193 - - 819,193 Interest receivable 4,542 4,542 - - 4,542 4,276 4,276 - - 4,276 Financial Liabilities: Interest bearing deposits $ 525,955 $ 525,955 $ - $ - $ 525,955 $ 532,660 $ 532,660 $ - $ - $ 532,660 Noninterest bearing deposits 215,422 215,422 - 215,422 - 199,114 199,114 - 199,114 - Time deposits 187,413 187,545 - - 187,545 187,566 188,335 - - 188,335 Total Deposits 928,790 928,922 - 215,422 713,500 919,340 920,109 - 199,114 720,995 Fed funds purchased and securities sold under agreement to repurchase 32,181 32,181 - - 32,181 39,495 39,495 - - 39,495 Federal Home Loan Bank advances - - - - - 5,000 5,021 - - 5,021 Interest payable 418 418 - - 418 318 318 - - 318 Fair Value Measurements The following table presents information about the Company’s assets and liabilities measured at fair value on a recurring basis at December 31, 2018 and 2017, 2018. 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. The quoted prices are not adjusted. 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 two 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.

There have been no transfers into or out of Level 3 during 2018 and 2017. The Company also has assets that, under certain conditions, are subject to measurement at fair value on a non-recurring basis. At December 31, 2018 and 2017, At December 31, 2018 and 2017, collateral dependent impaired loans categorized as Level 3 were $215 and $508 thousand, respectively. The specific allocation for collateral dependent impaired loans was $31 thousand as of December 31, 2018 December 31, 2017 Other real estate is reported at the lower of either the fair value of the real estate, minus the estimated costs to sell the asset, or the cost of the asset. The determination of the 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.

Subsequent Events [Abstract]
Subsequent Events	Note 20 – Subsequent Events On January 1, 2019, the Company acquired Limberlost Bancshares, Inc. (“Limberlost”), the bank holding company for Bank of Geneva, a community bank based in Geneva, Indiana. Bank of Geneva operated six full-service offices in the northeast Indiana communities of Geneva, Berne, Decatur, Monroe, Portland and Monroeville and was in the process of completing construction to relocate the Decatur office. Shareholders of Limberlost received 1,830 shares of FMAO common stock and $8,465.00 in cash for each share. Limberlost had 1,000 shares outstanding on January 1, 2019. The share price of Farmers & Merchants Bancorp, Inc. (FMAO) stock on January 1, 2019 was $38.49. Total consideration for the acquisition was approximately $78.9 million consisting of $8.5 million in cash and $70.4 million in stock. The most significant assets acquired were loans with a carrying value of $259.3 million and liabilities assumed were deposits with a carrying value of $206.6 million and other borrowings with a carrying value of $49.5 million. The Company has not yet finalized the purchase accounting or its final evaluations of the fair value of certain items. The primary areas of the purchase price allocation that are not yet finalized relate to the valuation of intangible assets, credit mark on loans, deposit and borrowings fair value marks and the residual goodwill. Any changes during the measurement period may have an impact on the allocation of the purchase price, including values assigned to assets, liabilities and the amount of estimated goodwill and intangible assets.

Accounting Policies [Abstract]
Nature of Operations	Nature of Operations The Farmers & Merchants Bancorp, Inc. (the Company) through its bank subsidiary, The Farmers & Merchants State Bank (the Bank) provides a variety of financial services to individuals and small businesses through its offices in Northwest Ohio and Northeast Indiana.
Consolidation Policy	Consolidation Policy The consolidated financial statements include the accounts of Farmers & Merchants Bancorp, Inc. and its wholly-owned subsidiaries, The Farmers & Merchants State Bank (the Bank), a commercial banking institution and Farmers & Merchants Risk Management, Inc. (the Captive), a Captive insurance company. All significant inter-company balances and transactions have been eliminated.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses and the valuation of mortgage servicing rights. Actual results could differ from those estimates. The determination of the adequacy of the allowance for loan losses is based on estimates that are particularly susceptible to significant changes in the economic environment and market conditions. In connection with the determination of the estimated losses on loans, management obtains independent appraisals for significant collateral. The Bank’s loans are generally secured by specific items of collateral including real property, consumer assets, and business assets. Although the Bank has a diversified loan portfolio, a substantial portion of its debtors’ ability to honor their contracts is dependent on local economic conditions in the agricultural industry. While management uses available information to recognize losses on loans, further reductions in the carrying amounts of loans may be necessary based on changes in local economic conditions. In addition regulatory agencies, as an integral part of their examination process, periodically review the estimated losses on loans. Such agencies may require the Bank to recognize additional losses based on their judgments about information available to them at the time of their examination. Because of these factors, it is reasonably possible that the estimated losses on loans may change materially in the near term. However, the amount of the change that is reasonably possible cannot be estimated.
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of the consolidated statement of cash flows, the Company considers all highly liquid debt instruments purchased with an original maturity of three months or less to be cash equivalents. This includes cash on hand, amounts due from banks, and federal funds sold. Generally, federal funds are purchased for one day periods.
Restrictions on Cash and Amounts Due from Banks	Restrictions on Cash and Amounts Due from Banks The Bank is required to maintain average balances on hand with the Federal Reserve Bank. The aggregate reserve was $12.6 million for December 31, 2018 and it was $11.4 million for December 31, 2017. The Company and its subsidiaries maintain cash balances with high quality credit institutions. At times such balances may be in excess of the federally insured limits.
Securities	Securities Debt securities are classified as available-for-sale. Securities available-for-sale are carried at fair value with unrealized gains and losses reported in other comprehensive income (loss). Net realized gains and losses on securities available for sale are included in noninterest income and, when applicable, are reported as a reclassification adjustment, net of tax, in other comprehensive income (loss). Gains and losses on sales of securities are determined on the specific-identification method. Declines in the fair value of securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses. In estimating other-than-temporary impairment losses, management considers (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. The related write-downs are included in earnings as realized losses.
Other Securities	Other Securities Other Securities is the Federal Home Loan Bank of Cincinnati stock which is held to enable the Bank to conduct business with the entity. The Federal Home Loan Bank sells and purchases their stock at par. The Federal Home Loan Bank of Cincinnati stock is carried at cost and held as collateral security for all indebtedness of the Bank to the Federal Home Loan Bank. The Federal Home Loan Bank of Cincinnati is evaluated for impairment as conditions warrant.
Loans	Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are reported at the amount of unpaid principal, reduced by unearned discounts and deferred loan fees and costs, as well as, by the allowance for loan losses. Interest income is accrued on a daily basis based on the principal outstanding. Generally, a loan is classified as nonaccrual and the accrual of interest income is generally discontinued when a loan becomes ninety days past due as to principal or interest and these loans are placed on a “cash basis” for purposes of income recognition. Management may elect to continue the accrual of interest when the estimated net realizable value of collateral is sufficient to cover the principal and accrued interest, and the loan is in the process of collection. When a loan is placed on nonaccrual status, all previously accrued and unpaid interest receivable is charged against income. Loan origination and commitment fees and certain direct loan origination costs are deferred and amortized as a net adjustment to the related loan’s yield. The Bank is generally amortizing these costs over the contractual life of such loans.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses is established through a provision for loan losses charged to income. Loans deemed to be uncollectable and changes in the allowance relating to loans are charged against the allowance for loan losses, and subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based on management’s periodic review of the collectability of the loans in light of historical experiences, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective, as it requires estimates that are subject to revision as more information becomes available. The allowance consists of specific, general and unallocated components. The specific component relates to loans that are classified as doubtful, substandard or special mention. For such loans that are also classified as impaired, an allowance is established when the discounted cash flows (or collateral value) of the impaired loan is lower than the carrying value of that loan. The general component covers non-classified loans and is based on historical loss experience adjusted for qualitative factors. The unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including length of the delay, the reasons for the delay, the borrower's prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan by loan basis for commercial and agricultural loans by either the present value of expected future cash flows discounted at the loan's effective interest rate or the fair value of the collateral if the loan is collateral dependent. At 90 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. 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. Large groups of homogeneous loans are collectively evaluated for impairment. Accordingly, the Bank does not separately identify individual consumer loans for impairment, unless such loans are the subject of a restructuring agreement due to financial difficulties of the borrower. For more information regarding the actual composition and classification of loans involved in the establishment of the allowance for loan loss, please see Note 4 provided here with the notes to consolidated financial statements.
Loans Held for Sale	Loans Held for Sale Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value in the aggregate. Net unrealized losses, if any, are recognized in a valuation allowance by charges to income.
Servicing Assets	Servicing Assets Servicing assets are recognized as separate assets when rights are acquired through purchase or sale of financial assets. Capitalized servicing rights are amortized into noninterest expense in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets. Servicing assets are evaluated for impairment based upon the fair value of the rights as compared to amortized cost. Impairment is determined by stratifying rights by predominant characteristics, such as interest rates and terms. Fair value is determined using prices for similar assets with similar characteristics, when available, or based upon discounted cash flows using market based assumptions. Impairment is recognized through a valuation allowance for an individual stratum, to the extent that fair value is less than the capitalized amount for the stratum. Fees received for servicing loans owned by investors are based on a percentage of the outstanding monthly principal balance of such loans and are included in operating income as loan payments are received. Costs of servicing loans are charged to expense as incurred.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill results from business acquisitions and represents the excess of the purchase price over the fair value of acquired tangible assets and liabilities and identifiable intangible assets. Goodwill is assessed at least annually. If possible impairment is likely, the Bank will utilize the assistance of an independent third party for impairment and any such impairment is recognized in the period identified. Periodically the Bank will have an independent third party assess the possibility of impairment of Goodwill. Such an assessment was performed as of September 30, 2017. The goodwill impairment analysis consisted of a first step goodwill impairment test which was used to identify potential impairment by comparing the fair value of the relevant reporting unity with its carrying value, including goodwill. The analysis was performed under guidance of FASB ASC 350. The engagement would have expanded to the second step goodwill impairment valuation if necessary; however, the findings showed the second step was not warranted. The analysis confirmed no impairment was likely. In quantitative testing done in 2018, the excess fair value of capital was $58.5 million or 51.1% over the carrying value and was over fourteen times the value of the goodwill being carried Therefore, the Bank concluded it is unlikely impairment of Goodwill has occurred from the goodwill established from the Bank’s acquisition which occurred on December 31, 2007. Other intangible assets consist of core deposit intangible assets arising from business acquisitions. They are initially measured at fair value and then are amortized on a straight line method over their estimated useful lives and evaluated for impairment. These assets are included in other assets on the consolidated balance sheets.
Off Balance Sheet Instruments	Off Balance Sheet Instruments In the ordinary course of business, the Bank has entered into commitments to extend credit, including commitments under credit card arrangements, commercial letters of credit and standby letters of credit. Such financial instruments are recorded when they are funded.
Foreclosed Real Estate	Foreclosed Real Estate Foreclosed real estate held for sale is carried at the lower of fair value minus estimated costs to sell, or cost. Costs of holding foreclosed real estate are charged to expense in the current period, except for significant property improvements, which are capitalized. Valuations are periodically performed by management and an allowance is established by a charge to non-interest expense if the carrying value exceeds the fair value minus the estimated costs to sell. Foreclosed real estate is classified as other real estate owned. The net loss from operations of foreclosed real estate held for sale is reported in non-interest expense. At December 31, the Bank’s holding of other real estate owned totaled $600 thousand and approximately $674 thousand for 2018 and 2017
Bank Premises and Equipment	Bank Premises and Equipment Land is carried at cost. Bank premises and equipment are stated at cost less accumulated depreciation. Depreciation is based on the estimated useful lives of the various properties and is computed using straight line and accelerated methods. Costs for maintenance and repairs are charged to operations as incurred. Gains and losses on dispositions are included in current operations.
Revenue Recognition	Revenue Recognition Accounting Standards Codification 606, “Revenue from Contracts with Customer” (ASC 606) provides that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Revenue generated from financial instruments, including loans and investment securities, are not included within the scope of ASC 606. The adoption of ASC 606 did not result in a change to the accounting for any of the Company’s revenue streams that are within scope of the amendments. Revenue-generating activities that are within the scope of ASC 606 that are presented as non-interest income in the Company’s consolidated statements of income include: o Customer service fees – these include miscellaneous service fees and transaction-based fees charged for certain services, such as debit card or credit card. Revenue is recognized when the performance obligation is completed, which is generally after a transaction is completed or monthly for account maintenance services. o Other service charges and fees – these include service fees charged for deposit account maintenance and activity along with transaction-based fees charged for certain services, such as overdraft activities, returned check charges and wire transfers. Revenue is recognized when the performance obligation is completed, which is generally after a transaction is completed or monthly for account maintenance services.
Federal Income Tax	Federal Income Tax The Company’s income tax expense consists of the following components: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management’s judgment. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits in tax expense. Based on management’s analysis, the Company did not have any uncertain tax positions as of December 31, 2018 and 2017
Earnings Per Share	Earnings Per Share Basic earnings per share represent income available to common stockholders divided by the weighted-average number of common shares outstanding during the period. On August 18, 2017, the Company’s Board of Directors authorized a two-for-one stock split payable on September 20, 2017, for shareholders of record on September 5, 2017. See Note 12 for additional information.
Stock-Based Compensation	Stock-Based Compensation The fair value of restricted common stock is their fair market value on the date of grant. The fair value of restricted stock is amortized as compensation expense on a straight-line basis over the vesting period of the grants. Compensation expense recognized is included in salaries and wages in the consolidated statements of income.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Corporation – put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets and (3) the Corporation does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.
Treasury Stock	Treasury Stock Common stock shares repurchased are recorded at market value on date of purchase.
Other Comprehensive Income (Loss)	Other Comprehensive Income (Loss) Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale securities, are reported as a separate component of the equity section of the balance sheet. Such items, along with net income, are components of other comprehensive income (loss). The company adopted ASU 2018-02 on January 1, 2018 and elected to reclassify the income tax effects of the Tax Cuts and Job Act from AOCI to retained earnings. The reclassification increased retained earnings and decreased AOCI by $359 thousand, with zero net effect on total stockholder’s equity. The components of other comprehensive income (loss) and related tax effects are as follows: (In Thousands) 2018 2017 2016 Net unrealized gain (loss) on available-for-sale securities $ (1,058 ) $ 267 $ (2,721 ) Reclassification adjustment for (gain) loss on sale of available-for-sale securities 9 (47 ) (588 ) Net unrealized gain (loss) on available-for-sale securities (1,049 ) 220 (3,309 ) Tax expense (benefit) (220 ) 74 (1,125 ) Other comprehensive income (loss) $ (829 ) $ 146 $ (2,184 )

Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the FASB issued ASU No. 2014-09 “Revenue from Contracts with Customers (Topic 606) i.e In January 2016, the FASB issued ASU No. 2016-01 “Financial Instruments - Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities.” In February 2016, the FASB issued ASU No. 2016-02 “Leases (Topic 842).” In June Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The ASU is effective for SEC filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019 (i.e., January 1, 2020, for calendar year entities). Early application will be permitted for all organizations for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company has contracted with an external advisor and has formed a committee to determine the methodology to be used. Most importantly, the Company is gathering as much data as possible to enable review scenarios and determine which calculations will produce the most reliable results. The Company is in the early stages of CECL conversion analysis with use of a third party service provider. In November 2016, the FASB issued ASU No. 2016-18 “Statement of Cash Flows (Topic 230) – Restricted Cash.” In January 2017, the FASB issued ASU No. 2017-01 “Business Combinations (Topic 805) – Clarifying the Definition of a Business.” In January 2017, the FASB issued ASU No. 2017-04 “Intangibles – Goodwill and other (Topic 350) – Simplifying the Test for Goodwill Impairment.” In March 2017, the FASB issued ASU No. 2017-08 “Receivables – Nonrefundable Fees and Other Cost (Subtopic 310-20), Premium Amortization on Purchased Callable Debit Securities.” In February 2018, the FASB issued ASU No. 2018-02 “ Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” In March 2018, the FASB issued No. ASU 2018-05 “Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin (SAB) No. 118.” In June 2018, the FASB issued ASU No. 2018-07 “Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting.” These amendments expand the scope of Topic 718, Compensation – Stock Compensation (which currently only includes share-based payments to employees) to include share-based payments issued to nonemployees for goods or services. Consequently, the accounting for share-based payments to nonemployees and employees will be substantially aligned. The ASU supersedes Subtopic 505-50, Equity – Equity-Based Payments to Non-Employees. The guidance is effective for public companies for fiscal years, and interim fiscal periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, but no earlier than a company’s adoption date of Topic 606, Revenue from Contracts with Customers. At this time, the Company has adopted as of December 31, 2018 and does not recognize the existence of any non-employee relationships involving share-based payments. In August 2018, the FASB issued ASU No. 2018-13 “Fair Value Measurement (Topic 820) - Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measuremen
