Significant Accounting Policies [Abstract]
Significant Accounting Policies	1. Significant Accounting Policies Farmers & Merchants Bancorp (the “Company”) was organized March 10, 1999. Primary operations are related to traditional banking activities through its subsidiary Farmers & Merchants Bank of Central California (the “Bank”) which was established in 1916. The Bank’s wholly owned subsidiaries include Farmers & Merchants Investment Corporation and Farmers/Merchants Corp. Farmers & Merchants Investment Corporation has been dormant since 1991. Farmers/Merchants Corp. acts as trustee on deeds of trust originated by the Bank. The Company’s other wholly owned subsidiaries include F & M Bancorp, Inc. and FMCB Statutory Trust I. F & M Bancorp, Inc. was created in March 2002 to protect the name F & M Bank. During 2002, the Company completed a fictitious name filing in California to begin using the streamlined name “F & M Bank” as part of a larger effort to enhance the Company’s image and build brand name recognition. In December 2003, the Company formed a wholly owned subsidiary, FMCB Statutory Trust I, for the sole purpose of issuing Trust Preferred Securities and related subordinated debentures, in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). FMCB Statutory Trust I is a non-consolidated subsidiary. The accounting and reporting policies of the Company conform to U.S. GAAP and prevailing practice within the banking industry. The following is a summary of the significant accounting and reporting policies used in preparing the consolidated financial statements. Basis of Presentation The accompanying consolidated financial statements and notes thereto have been prepared in accordance with accounting principles generally accepted in the United States of America for financial information. The accompanying consolidated financial statements include the accounts of the Company and the Company’s wholly owned subsidiaries, F & M Bancorp, Inc. and the Bank, along with the Bank’s wholly owned subsidiaries, Farmers & Merchants Investment Corporation and Farmers/Merchants Corp. Significant inter-company transactions have been eliminated in consolidation. The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. Cash and Cash Equivalents For purposes of the Consolidated Statements of Cash Flows, the Company has defined cash and cash equivalents as those amounts included in the balance sheet captions Cash and Due from Banks, Interest Bearing Deposits with Banks, Federal Funds Sold which have maturity dates of 3 months or less. For these instruments, the carrying amount is a reasonable estimate of fair value. Investment Securities Investment securities are classified at the time of purchase as held-to-maturity (“HTM”) if it is management’s intent and the Company has the ability to hold the securities until maturity. These securities are carried at cost, adjusted for amortization of premium to earliest call date and accretion of discount using a level yield of interest over the estimated remaining period until maturity. Losses, reflecting a decline in value judged by the Company to be other than temporary, are recognized in the period in which they occur. Securities are classified as available-for-sale (“AFS”) if it is management’s intent, at the time of purchase, to hold the securities for an indefinite period of time and/or to use the securities as part of the Company’s asset/liability management strategy. These securities are reported at fair value with aggregate unrealized gains or losses excluded from income and included as a separate component of shareholders’ equity, net of related income taxes. Fair values are based on quoted market prices or broker/dealer price quotations on a specific identification basis. Gains or losses on the sale of these securities are computed using the specific identification method. Trading securities, if any, are acquired for short-term appreciation and are recorded in a trading portfolio and are carried at fair value, with unrealized gains and losses recorded in non-interest income. Management evaluates securities for other-than-temporary impairment (“OTTI”) on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss, and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: (1) OTTI related to credit loss, which must be recognized in the income statement; and (2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of a market adjustment is recognized through earnings. Loans & Leases Loans & leases are reported at the principal amount outstanding net of unearned discounts and deferred loan & lease fees and costs. Interest income on loans & leases is accrued daily on the outstanding balances using the simple interest method. Loan & lease origination fees are deferred and recognized over the contractual life of the loan or lease as an adjustment to the yield. Loans & leases are placed on non-accrual status when the collection of principal or interest is in doubt or when they become past due for 90 days or more unless they are both well-secured and in the process of collection. For this purpose, a loan or lease is considered well-secured if it is collateralized by property having a net realizable value in excess of the amount of the loan or lease or is guaranteed by a financially capable party. When a loan or lease is placed on non-accrual status, the accrued and unpaid interest receivable is reversed and charged against current income; thereafter, interest income is recognized only as it is collected in cash. Additionally, cash would be applied to principal if all principal was not expected to be collected. Loans & leases placed on non-accrual status are returned to accrual status when the loans or leases are paid current as to principal and interest and future payments are expected to be made in accordance with the contractual terms of the loan or lease. A loan or lease is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due, including principal and interest, according to the contractual terms of the original agreement. Impaired loans & leases are either: (1) non-accrual loans & leases; or (2) restructured loans & leases that are still accruing interest. Loans or leases determined to be impaired are individually evaluated for impairment. When a loan or lease is impaired, the Company measures impairment based on the present value of expected future cash flows discounted at the loan or lease's effective interest rate, except that as a practical expedient, it may measure impairment based on a loan or lease's observable market price, or the fair value of the collateral if the loan or lease is collateral dependent. A loan or lease is collateral dependent if the repayment of the loan or lease is expected to be provided solely by the underlying collateral. A restructuring of a loan or lease constitutes a troubled debt restructuring (TDR) if the Company for economic or legal reasons related to the borrower’s (the term “borrower” is used herein to describe a customer who has entered into either a loan or lease transaction) financial difficulties grants a more than insignificant concession to the borrower that it would not otherwise consider. Restructured loans & leases typically present an elevated level of credit risk as the borrowers are not able to perform according to the original contractual terms. If the restructured loan or lease was current on all payments at the time of restructure and management reasonably expects the borrower will continue to perform after the restructure, management may keep the loan or lease on accrual. Loans & leases that are on nonaccrual status at the time they become TDR, remain on nonaccrual status until the borrower demonstrates a sustained period of performance, which the Company generally believes to be six Generally, the Company will not restructure loans or leases for borrowers unless: (1) the existing loan or lease is brought current as to principal and interest payments; and (2) the restructured loan or lease can be underwritten to reasonable underwriting standards. If these standards are not met other actions will be pursued (e.g., foreclosure) to collect outstanding loan or lease amounts. After restructure, a determination is made whether the loan or lease will be kept on accrual status based upon the underwriting and historical performance of the restructured credit. On March 27, 2020, the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was signed into law by Congress. The CARES Act provides financial institutions, under specific circumstances, the opportunity to temporarily suspend certain requirements under generally accepted accounting principles related to modifications for a limited period of time to account for the effects of COVID-19. In March 2020, a joint statement was issued by federal and state regulatory agencies, after consultation with the FASB, to clarify that short-term loan modifications, such as payment deferrals, fee waivers, extensions of repayment terms or other insignificant payment delays, are not TDRs if made on a good-faith basis in response to COVID-19 to borrowers who were current prior to any relief. Under this guidance, six months or less is provided as an example of short-term, and current is defined as less than 30 days past due at the time the modification program is implemented. The guidance also provides that these modified loans generally are not classified as nonaccrual during the term of the modification. See “Note 2 – Risks and Uncertainties” for additional information on the CARES Act and the impact of COVID-19 on the Company. Allowance for Credit Losses The allowance for credit losses is an estimate of probable incurred credit losses inherent in the Company's loan & lease portfolio as of the balance sheet date. The allowance is established through a provision for credit losses, which is charged to expense. Additions to the allowance are expected to maintain the adequacy of the total allowance after credit losses and loan & lease growth. Credit exposures determined to be uncollectible are charged against the allowance. Cash received on previously charged off amounts is recorded as a recovery to the allowance. The overall allowance consists of three primary components: specific reserves related to impaired loans & leases; general reserves for inherent losses related to loans & leases that are not impaired; and an unallocated component that takes into account the imprecision in estimating and allocating allowance balances associated with macro factors. The determination of the general reserve for loans & leases that are collectively evaluated for impairment is based on estimates made by management, to include, but not limited to, consideration of historical losses by portfolio segment, internal asset classifications, qualitative factors that include economic trends in the Company's service areas, industry experience and trends, geographic concentrations, estimated collateral values, the Company's underwriting policies, the character of the loan & lease portfolio, and probable losses inherent in the portfolio taken as a whole. The Company maintains a separate allowance for each portfolio segment (loan & lease type). These portfolio segments include: (1) commercial real estate; (2) agricultural real estate; (3) real estate construction (including land and development loans); (4) residential 1 st The Company assigns a risk rating to all loans & leases and periodically performs detailed reviews of all such loans & leases over a certain threshold to identify credit risks and assess overall collectability. For smaller balance loans & leases, such as consumer and residential real estate, a credit grade is established at inception, and then updated only when the loan or lease becomes contractually delinquent or when the borrower requests a modification. For larger balance loans, management monitors and analyzes the financial condition of borrowers and guarantors, trends in the industries in which borrowers operate and the fair values of collateral securing these loans & leases. These credit quality indicators are used to assign a risk rating to each individual loan or lease. These risk ratings are also subject to examination by independent specialists engaged by the Company. The risk ratings can be grouped into five major categories, defined as follows: Pass – A pass loan or lease is a strong credit with no existing or known potential weaknesses deserving of management's close attention. Special Mention – A special mention loan or lease has potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or lease or in the Company's credit position at some future date. Special mention loans & leases are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification. Substandard – A substandard loan or lease is not adequately protected by the current financial condition and paying capacity of the borrower or the value of the collateral pledged, if any. Loans or leases classified as substandard have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. Well-defined weaknesses include a project's lack of marketability, inadequate cash flow or collateral support, failure to complete construction on time or the project's failure to fulfill economic expectations. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Doubtful – Loans or leases classified doubtful have all the weaknesses inherent in those classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, based on currently known facts, conditions and values, highly questionable or improbable. Loss – Loans or leases classified as loss are considered uncollectible. Once a loan or lease becomes delinquent and repayment becomes questionable, the Company will address collateral shortfalls with the borrower and attempt to obtain additional collateral. If this is not forthcoming and payment in full is unlikely, the Company will estimate its probable loss and immediately charge-off some or all of the balance. The general reserve component of the allowance for credit losses also consists of reserve factors that are based on management's assessment of the following for each portfolio segment: (1) inherent credit risk; (2) historical losses; and (3) other qualitative factors. These reserve factors are inherently subjective and are driven by the repayment risk associated with each portfolio segment described below: Commercial Real Estate – Commercial real estate mortgage loans are generally considered to possess a higher inherent risk of loss than the Company’s commercial, agricultural and consumer loan types. Adverse economic developments or an overbuilt market impact commercial real estate projects and may result in troubled loans. Trends in vacancy rates of commercial properties impact the credit quality of these loans. High vacancy rates reduce operating revenues and the ability for properties to produce sufficient cash flow to service debt obligations. Real Estate Construction – Real estate construction loans, including land loans, are generally considered to possess a higher inherent risk of loss than the Company’s commercial, agricultural and consumer loan types. A major risk arises from the necessity to complete projects within specified cost and time lines. Trends in the construction industry significantly impact the credit quality of these loans, as demand drives construction activity. In addition, trends in real estate values significantly impact the credit quality of these loans, as property values determine the economic viability of construction projects. Commercial – These loans are generally considered to possess a moderate inherent risk of loss because they are shorter-term; typically made to relationship customers; generally underwritten to existing cash flows of operating businesses; and may be collateralized by fixed assets, inventory and/or accounts receivable. Debt coverage is provided by business cash flows and economic trends influenced by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans. Agricultural Real Estate and Agricultural – These loans are generally considered to possess a moderate inherent risk of loss since they are typically made to relationship customers and are secured by crop production, livestock and related real estate. These loans are vulnerable to two risk factors that are largely outside the control of Company and borrowers: commodity prices and weather conditions. Leases – Equipment leases are generally considered to possess a moderate inherent risk of loss. As lessor, the Company is subject to both the credit risk of the borrower and the residual value risk of the equipment. Credit risks are underwritten using the same credit criteria the Company would use when making an equipment term loan. Residual value risk is managed through the use of qualified, independent appraisers that establish the residual values the Company uses in structuring a lease. Residential 1st Mortgages and Home Equity Lines and Loans – These loans are generally considered to possess a lower inherent risk of loss. The degree of risk in residential real estate lending depends primarily on the loan amount in relation to collateral value, the interest rate and the borrower's ability to repay in an orderly fashion. Economic trends determined by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans. Weak economic trends indicate that the borrowers' capacity to repay their obligations may be deteriorating. Consumer & Other – A consumer installment loan portfolio is usually comprised of a large number of small loans scheduled to be amortized over a specific period. Most installment loans are made for consumer purchases. Economic trends determined by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans. Weak economic trends indicate that the borrowers' capacity to repay their obligations may be deteriorating. At least quarterly, the Board of Directors reviews the adequacy of the allowance, including consideration of the relative risks in the portfolio, current economic conditions and other factors. If the Board of Directors and management determine that changes are warranted based on those reviews, the allowance is adjusted. In addition, the Company's and Bank's regulators, including the Federal Reserve Board (“FRB”), the California Department of Business Oversight (“DBO”) and the Federal Deposit Insurance Corporation (“FDIC”), as an integral part of their examination process, review the adequacy of the allowance. These regulatory agencies may require additions to the allowance based on their judgment about information available at the time of their examinations. Acquired Loans Loans acquired through purchase or through a business combination are recorded at their fair value at the acquisition date. Credit discounts, which reflect estimates of credit losses, expected to be incurred over the life of the loan, are included in the determination of fair value; therefore, an allowance for loan losses is not recorded at the acquisition date. Allowance for Credit Losses on Off-Balance-Sheet Credit Exposures The Company also maintains a separate allowance for off-balance-sheet commitments. Management estimates anticipated losses using historical data and utilization assumptions. The allowance for off-balance-sheet commitments is included in Interest Payable and Other Liabilities on the Company’s Consolidated Balance Sheet. Premises and Equipment Premises, equipment, and leasehold improvements are stated at cost, less accumulated depreciation and amortization. Depreciation is computed principally by the straight-line method over the estimated useful lives of the assets. Estimated useful lives of buildings range from 30 to 40 years, and for furniture and equipment from 3 to 7 years. Leasehold improvements are amortized over the lesser of the terms of the respective leases, or their useful lives, which are generally 5 to 10 years. Remodeling and capital improvements are capitalized while maintenance and repairs are charged directly to occupancy expense. Other Real Estate Other real estate, which is included in other assets, is expected to be sold and is comprised of properties no longer utilized for business operations and property acquired through foreclosure in satisfaction of indebtedness. These properties are recorded at fair value less estimated selling costs upon acquisition. Revised estimates to the fair value less cost to sell are reported as adjustments to the carrying amount of the asset, provided that such adjusted value is not in excess of the carrying amount at acquisition. Initial losses on properties acquired through full or partial satisfaction of debt are treated as credit losses and charged to the allowance for credit losses at the time of acquisition. Subsequent declines in value from the recorded amounts, routine holding costs, and gains or losses upon disposition, if any, are included in non-interest expense as incurred. On March 27, 2020 the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was signed into law by Congress. The CARES Act restricts the ability of financial institutions to exercise their foreclosure rights on residential and multi-family properties backed by federally guaranteed mortgage loans. The State of California has gone further and temporarily suspended all residential and commercial foreclosures. The Company is working with its borrowers when they make requests to defer payments on their mortgage loans. See “Note 2 – Risks and Uncertainties” for additional information on the CARES Act and the impact of COVID-19 on the Company. Income Taxes The Company uses the liability method of accounting for income taxes. This method results in the recognition of deferred tax assets and liabilities that are reflected at currently enacted income tax rates applicable to the period in which the deferred tax assets or liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. The deferred provision for income taxes is the result of the net change in the deferred tax asset and deferred tax liability balances during the year. This amount combined with the current taxes payable or refundable results in the income tax expense for the current year. The Company follows the standards set forth in the “Income Taxes” topic of the Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”), which clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. This standard prescribes a recognition threshold and measurement standard for the financial statement recognition and measurement of an income tax position taken or expected to be taken in a tax return. It also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. The Company accounts for leases with Investment Tax Credits (ITC) under the deferred method as established in ASC 740-10. ITC are viewed and accounted for as a reduction of the cost of the related assets and presented as deferred income on the Company’s financial statement. The Company accounts for its interest in Low Income Housing Tax Credits (LIHTC) using the cost method as established in ASC 323-740. As an investor, the Company obtains income tax credits and deductions from the operating losses of these tax credit entities. The income tax credits and deductions are allocated to the investors based on their ownership percentages and are recorded as a reduction of income tax expense (or an increase to income tax benefit) and a reduction of federal income taxes payable. When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the accompanying consolidated balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination. For the three and six months ended June 30, 2020 and 2019, the Company has no material uncertain tax positions and recognized no interest or penalties. The Company's policy is to recognize interest and penalties related to income taxes in the provision for income taxes in the Consolidated Statement of Income. Basic and Diluted Earnings Per Common Share The Company’s common stock is not traded on any exchange. However, trades are reported on the OTCQX under the symbol "FMCB". The shares are primarily held by local residents and are not actively traded. Basic earnings per common share amounts are computed by dividing net income by the weighted average number of common shares outstanding for the period. There are no common stock equivalent shares. Therefore, diluted and basic earnings per common share are the same. See Note 8 – “Dividends and Basic Earnings Per Common Share” for additional information. Segment Reporting The “Segment Reporting” topic of the FASB ASC requires that public companies report certain information about operating segments. It also requires that public companies report certain information about their products and services, the geographic areas in which they operate, and their major customers. The Company is a holding company for a community bank, which offers a wide array of products and services to its customers. Pursuant to its banking strategy, emphasis is placed on building relationships with its customers, as opposed to building specific lines of business. As a result, the Company is not organized around discernible lines of business and prefers to work as an integrated unit to customize solutions for its customers, with business line emphasis and product offerings changing over time as needs and demands change. Comprehensive Income The “Comprehensive Income” topic of the FASB ASC establishes standards for the reporting and display of comprehensive income and its components in the financial statements. Other comprehensive income refers to revenues, expenses, gains, and losses that U.S. GAAP recognize as changes in value to an enterprise but are excluded from net income. For the Company, comprehensive income includes net income and changes in fair value of its available-for-sale investment securities. Loss Contingencies Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there now are such matters that will have a material effect on the consolidated financial statements. Business Combinations And Related Matters Business combinations are accounted for under the acquisition method of accounting in accordance with ASC 805, Business Combinations. Under the acquisition method, the acquiring entity in a business combination recognizes 100 percent of the acquired assets and assumed liabilities, regardless of the percentage owned, at their estimated fair values as of the date of acquisition. Any excess of the fair value over the purchase price of net assets and other identifiable intangible assets acquired is recorded as bargain purchase gain. Assets acquired and liabilities assumed from contingencies must also be recognized at fair value, if the fair value can be determined during the measurement period. Results of operations of an acquired business are included in the statement of operations from the date of acquisition. Acquisition-related costs, including conversion charges, are expensed as incurred. Goodwill and Other Intangible Assets Goodwill is determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill that arises from a business combination is periodically evaluated for impairment at the reporting unit level, at least annually. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Core deposit intangible ("CDI") represents the estimated future benefit of deposits related to an acquisition and is booked separately from the related deposits and evaluated periodically for impairment. The CDI asset is amortized on a straight-line method over its estimated useful life of ten years. At June 30, 2020, the future estimated amortization expense for the CDI arising from our past acquisitions is as follows: (in thousands) 2020 2021 2022 2023 2024 Thereafter Total Core Deposit Intangible Amortization $ 312 $ 611 $ 593 $ 573 $ 549 $ 1,688 $ 4,326 We make a qualitative assessment of whether it is more likely than not that the fair value of a reporting unit where goodwill is assigned is less than its carrying amount. If we conclude that it is more likely than not that the fair value is more than its carrying amount, no impairment is recorded. Goodwill is tested for impairment on an interim basis if circumstances change or an event occurs between annual tests that would more likely than not reduce the fair value of the reporting unit below its carrying amount. The qualitative assessment includes adverse events or circumstances identified that could negatively affect the reporting units’ fair value as well as positive and mitigating events. Such indicators may include, among others, a significant change in legal factors or in the general business climate, significant change in our stock price and market capitalization, unanticipated competition, and an action or assessment by a regulator. If the fair value of a reporting unit is less than its carrying amount, an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value is recognized. The loss recognized should not exceed the total amount of goodwill allocated to that reporting un

Risks and Uncertainties	2. Risks and Uncertainties The COVID-19 pandemic has affected all of us. Designated as an “essential business”, the Company’s subsidiary, Farmers & Merchants Bank of Central California, has kept all branches open and maintained regular business hours during these difficult times. Our staffing levels have remained stable during the COVID-19 crisis. We have taken what we believe are prudent measures to protect our employees and customers, while still providing core banking services. On March 27, 2020, the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was signed into law. Through this legislation, as well as related federal and state regulatory actions, the federal government has taken extraordinary efforts to provide financial assistance to individuals and companies to help them move through these difficult times. However, there are no guaranties how long the COVID-19 virus may continue to impact our economy, and therefore, the Company. While we expect the effects of COVID-19 to have an adverse future impact on our business, financial condition and results of operations, we are unable to predict the full extent or nature of these impacts at the current time.

Management periodically evaluates each investment security for other-than-temporary impairment relying primarily on industry analyst reports and observations of market conditions and interest rate fluctuations. Management believes it will be able to collect all amounts due according to the contractual terms of the underlying investment securities. Securities of Government Agency and Government Sponsored Entities – At June 30, 2020 securities of government agency and government sponsored entities were in an unrealized loss position for less than 12 months, and were in an unrealized loss position for 12 months or more. The unrealized losses on the Company's investments in securities of government agency and government sponsored entities were at June 30, 2020, December 31, 2019 and June 30, 2019 respectively. U.S. Treasury Notes – At June 30, 2020 U.S. Treasury Note security investment was in an unrealized loss position for less than 12 months and were in an unrealized loss position for 12 months or more. The unrealized loss on the Company's investment in a U.S. Treasury Note was and at June 30, 2020, December 31, 2019 and June 30, 2019 respectively. The unrealized losses were caused by interest rate fluctuations. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell the securities and it is more likely than not that the Company will not have to sell the securities before recovery of their cost basis, the Company did not consider these investments to be other-than-temporarily impaired at June 30, 2020, December 31, 2019 and June 30, 2019 U.S. Government SBA – At June 30, 2020 U.S. Government SBA security investments were in an unrealized loss position for less than 12 months and were in an unrealized loss position for 12 months or more. The unrealized losses on the Company's investment in U.S. Government SBA securities were and at June 30, 2020, December 31, 2019 and June 30, 2019 respectively. The unrealized losses were caused by interest rate fluctuations. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell the securities and it is more likely than not that the Company will not have to sell the securities before recovery of their cost basis, the Company did not consider these investments to be other-than-temporarily impaired at June 30, 2020, December 31, 2019 and June 30, 2019 Mortgage Backed Securities – At June 30, 2020 mortgage backed security investment was in an unrealized loss position for less than 12 months and were in an unrealized loss position for 12 months or more. The unrealized losses on the Company's investment in mortgage backed securities were and at June 30, 2020, December 31, 2019 and June 30, 2019 respectively. The unrealized losses were caused by interest rate fluctuations. The contractual cash flows of these investments are guaranteed by an agency or government sponsored entity of the U.S. government. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost of the Company's investment. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell the securities and it is more likely than not that the Company will not have to sell the securities before recovery of their cost basis, the Company did not consider these investments to be other-than-temporarily impaired at June 30, 2020, December 31, 2019 and June 30, 2019 Obligations of States and Political Subdivisions – At June 30, 2020 obligations of states and political subdivisions were in an unrealized loss position for less than 12 months. were in an unrealized loss position for 12 months or more. As of June 30, 2020 the Company’s bank-qualified municipal bond portfolio was rated at either the issue or issuer level, and all of these ratings were “investment grade.” The Company monitors the status of all municipal investments in the portfolio and at the current time does not believe any of them to be exhibiting financial problems that could result in a loss in any individual security. The unrealized losses on the Company’s investment in obligations of states and political subdivisions were and at June 30, 2020, December 31, 2019 and June 30, 2019 respectively. Management believes that any unrealized losses on the Company's investments in obligations of states and political subdivisions were caused by interest rate fluctuations. The contractual terms of these investments do not permit the issuer to settle the securities at a price less than the amortized cost of the investment. Because the Company does not intend to sell the securities and it is more likely than not that the Company would not have to sell the securities before recovery of their cost basis, the Company did not consider these investments to be other-than-temporarily impaired at June 30, 2020, December 31, 2019 and June 30, 2019 Corporate Securities - At June 30, 2020 corporate security was in an unrealized loss position for less than 12 months. The unrealized loss on the Company’s investment in the corporate security was Changes in the prices of corporate securities are primarily influenced by: changes in market interest rates; changes in perceived credit risk in the general economy or in particular industries; changes in the perceived credit risk of a particular company; and day to day trading supply, demand and liquidity. Because the Company does not intend to sell the securities and it is more likely than not that the Company will not have to sell the securities before recovery of their cost basis, the Company does not consider these investments to be other-than-temporarily impaired at June 30, 2020 Proceeds from sales and calls of securities were as follows: Three Months Ended Six Months Ended (in s) 2020 2019 2020 2019 Proceeds $ 745 $ 1,310 $ 3,000 $ 1,310 Gains - - 13 - Losses - - - - Pledged Securities As of June 30, 2020, securities carried at $370.4 million were pledged to secure public deposits, Federal Home Loan Bank (“FHLB”) borrowings, and other government agency deposits as required by law.

Paycheck Protection Program (“PPP”) … Under the CARES Act (see “Note 2 – Risks and Uncertainties”) the Small Business Administration (“SBA”) was directed by Congress to provide up to $349 billion (subsequently expanded by an additional $310 billion) in loans to small businesses with less than 500 employees to assist these businesses in meeting their payroll and other financial obligations over the next several months. These government guaranteed loans are made with an interest rate of 1%, a risk weight of 0% under risk-based capital rules, have a term of 2 years, and under certain conditions the SBA can forgive them after eight weeks. Farmers & Merchants Bank of Central California actively participated in the PPP, and since April, 2020 the Bank has funded $347.4 million of loans for 1,536 small business customers.

This is because this table does not include impaired loans that were previously modified in a troubled debt restructuring, are currently performing and are no longer disclosed or classified as TDR’s. A loan or lease can be removed from TDR status if it was restructured at a market rate in a prior calendar year and is currently in compliance with its modified terms. However, these loans or leases continue to be classified as impaired and are individually evaluated for impairment. On March 27, 2020 the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was signed into law. The CARES Act provides financial institutions, under specific circumstances, the opportunity to temporarily suspend certain requirements under generally accepted accounting principles related to TDR’s for a limited period of time to account for the effects of COVID-19. In March 2020, a joint statement was issued by federal and state regulatory agencies, after consultation with the FASB, to clarify that short-term loan modifications are not TDRs if made on a good-faith basis in response to COVID-19 to borrowers who were current prior to any relief. Under this guidance, six months is provided as an example of short-term, and current is defined as less than 30 days past due at the time the modification program is implemented. The guidance also provides that these modified loans generally will not be classified as nonaccrual during the term of the modification. For the quarter ended June we restructured of loans under the CARES Act guidelines (primarily payment or interest deferrals up to months). We believe that these actions will assist these borrowers in getting through these difficult times, but no guaranties can be made that at some time in the future these loans will not be required to be accounted for as a TDR. For borrowers who are 30 days or more past due when enrolling in a loan modification program related to the COVID-19 pandemic, we evaluate the loan modifications under our existing TDR framework, and where such a loan modification would result in a more than insignificant concession to a borrower experiencing financial difficulty, the loan will be accounted for as a TDR and will generally not accrue interest. See “Note 2 – Risks and Uncertainties” for additional information on the CARES Act and the impact of COVID-19 on the Company. At June 30, 2020, the Company allocated $373,000 of specific reserves to $8.1 million of troubled debt restructured loans & leases, all of which were performing. The Company had no commitments at June 30, 2020 to lend additional amounts to customers with outstanding loans or leases that are classified as TDRs. During the six-month period ended June 30, 2020, there were five loans modified as a troubled debt restructuring. The modification involved a reduction of the stated interest rate of the loan for 5 years and extended the maturity date for 10 years. The following table presents loans or leases by class modified as troubled debt restructured loans or leases during the and -month periods ended June (in thousand s) : Three Months Ended June 30, 2020 Six Months Ended June 30, 2020 Troubled Debt Restructurings Number of Loans Pre-Modification Outstanding Recorded Investment Post- Modification Outstanding Recorded Investment Number of Loans Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment Residential 1st Mortgages - $ - $ - 5 $ 634 $ 634 Total - $ - $ - 5 $ 634 $ 634 During the three and six months ended June 30, 2020, the twelve months ended December 31, 2019, and the three and six-month periods ended June 30, 2019 there were no payment defaults on loans or leases modified as troubled debt restructurings within twelve months following the modification. The Company considers a loan or lease to be in payment default once it is greater than 90 days contractually past due under the modified terms. At December 31, 2019, the Company allocated $612,000 of specific reserves to $12.1 million of troubled debt restructured loans, all of which were performing. The Company had no commitments at December 31, 2019 to lend additional amounts to customers with outstanding loans that are classified as troubled debt restructurings. During the year ended December 31, 2019, the terms of certain loans were modified as troubled debt restructurings. The modification of the terms of such loans included one or a combination of the following: a reduction of the stated interest rate of the loan; an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk; or a permanent reduction of the recorded investment in the loan. There were no modifications involving a reduction of the stated interest rate. Modifications involving an extension of the maturity date ranged from 3 months to 6 years.

Fair Value Measurements [Abstract]
Fair Value Measurements	6. Fair Value Measurements The Company follows the “Fair Value Measurement and Disclosures” topic of the FASB ASC, which establishes a framework for measuring fair value in U.S. GAAP and expands disclosures about fair value measurements. This standard applies whenever other standards require, or permit, assets or liabilities to be measured at fair value but does not expand the use of fair value in any new circumstances. In this standard, the FASB clarifies the principle that fair value should be based on the assumptions market participants would use when pricing the asset or liability. In support of this principle, this standard establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. The fair value hierarchy is as follows: Level 1 inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date. Level 2 inputs - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets and liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs - Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. Management monitors the availability of observable market data to assess the appropriate classification of financial instruments within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, the transfer is reported at the beginning of the reporting period. Management evaluates the significance of transfers between levels based upon the nature of the financial instrument and size of the transfer relative to total assets, total liabilities or total earnings. Securities classified as available-for-sale are reported at fair value on a recurring basis utilizing Level 1, 2 and 3 inputs. For these securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond's terms and conditions, among other things. The Company does not record all loans & leases at fair value on a recurring basis. However, from time to time, a loan or lease is considered impaired and an allowance for credit losses is established. Once a loan or lease is identified as individually impaired, management measures impairment in accordance with the “Receivable” topic of the FASB ASC. The fair value of impaired loans or leases is estimated using one of several methods, including collateral value when the loan is collateral dependent, market value of similar debt, enterprise value, and discounted cash flows. Impaired loans & leases not requiring an allowance represent loans & leases for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans & leases. Impaired loans & leases where an allowance is established based on the fair value of collateral require classification in the fair value hierarchy. The fair value of collateral dependent impaired loans is generally based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including sales comparison, cost and the income approach. Adjustments are often made in the appraisal process by the appraisers to take into account differences between the comparable sales and income and other available data. Such adjustments can be significant and typically result in a Level 3 classification of the inputs for determining fair value. The valuation technique used for Level 3 nonrecurring impaired loans is primarily the sales comparison approach less selling costs of 10%. Other Real Estate (“ORE”) is reported at fair value on a non-recurring basis. Fair values are based on recent real estate appraisals. These appraisals may use a single valuation approach or a combination of approaches including sales comparison, cost and the income approach. Adjustments are often made in the appraisal process by the appraisers to take into account differences between the comparable sales and income and other available data. Such adjustments can be significant and typically result in a Level 3 classification of the inputs for determining fair value. The valuation technique used for Level 3 nonrecurring ORE is primarily the sales comparison approach less selling costs of 10%. The following tables present information about the Company’s assets measured at fair value on a recurring basis and indicate the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value for the periods indicated.

These adjustments may increase or decrease an appraised value and can vary significantly depending on the location, physical characteristics and income producing potential of each property. Additionally, the quality and volume of market information available at the time of the appraisal can vary from period to period and cause significant changes to the nature and magnitude of comparable sale adjustments. Given these variations, comparable sale adjustments are generally not a reliable indicator for how fair value will increase or decrease from period to period. Under certain circumstances, management discounts are applied based on specific characteristics of an individual property.

Fair Value of Financial Instruments [Abstract]
Fair Value of Financial Instruments	7. Fair Value of Financial Instruments U.S. GAAP requires disclosure of fair value information about financial instruments, whether or not recognized on the balance sheet, for which it is practical to estimate that value. The estimated fair value amounts have been determined by the Company using available market information and appropriate valuation methodologies. The use of assumptions and various valuation techniques, as well as the absence of secondary markets for certain financial instruments, will likely reduce the comparability of fair value disclosures between financial institutions. In some cases, book value is a reasonable estimate of fair value due to the relatively short period of time between origination of the instrument and its expected realization. The valuation of loans held for investment was impacted by the adoption of ASU 2016-01. In accordance with ASU 2016-01, the fair value of loans held for investment, excluding previously presented impaired loans measured at fair value on a non-recurring basis, is estimated using discounted cash flow analyses. The discount rates used to determine fair value use interest rate spreads that reflect factors such as liquidity, credit, and nonperformance risk of the loans. Loans are considered a Level 3 classification. The following tables summarize the book value and estimated fair value of financial instruments for the periods indicated: Fair Value of Financial Instruments Using June 30, 2020 (in thousands) Carrying Amount Quoted Prices in Active Markets for Identical Assets (Level 1) Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Estimated Fair Value Assets: Cash and Cash Equivalents $ 371,439 $ 371,439 $ - $ - $ 371,439 Investment Securities Available-for-Sale 569,407 80,691 488,716 - 569,407 Investment Securities Held-to-Maturity 69,036 - 28,893 41,301 70,194 Loans & Leases, Net 3,009,454 - - 3,001,079 3,001,079 Accrued Interest Receivable 18,083 - 18,083 - 18,083 Liabilities: Deposits 3,782,033 3,250,311 533,650 - 3,783,961 Subordinated Debentures 10,310 - 6,936 - 6,936 Accrued Interest Payable 2,183 - 2,183 - 2,183 Fair Value of Financial Instruments Using December 31, 2019 (in thousands) Carrying Amount Quoted Prices in Active Markets for Identical Assets (Level 1) Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Estimated Fair Value Assets: Cash and Cash Equivalents $ 294,758 $ 294,758 $ - $ - $ 294,758 Investment Securities Available-for-Sale 507,386 55,200 452,186 - 507,386 Investment Securities Held-to-Maturity 60,229 - 31,253 29,844 61,097 Loans & Leases, Net 2,618,015 - - 2,584,805 2,584,805 Accrued Interest Receivable 16,733 - 16,733 - 16,733 Liabilities: Deposits 3,278,019 2,760,097 517,172 - 3,277,269 Subordinated Debentures 10,310 - 7,325 - 7,325 Accrued Interest Payable 2,795 - 2,795 - 2,795 Fair Value of Financial Instruments Using June 30, 2019 (in thousands) Carrying Amount Quoted Prices in Active Markets for Identical Assets (Level 1) Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Estimated Fair Value Assets: Cash and Cash Equivalents $ 114,717 $ 114,717 $ - $ - $ 114,717 Investment Securities Available-for-Sale 488,093 175,111 308,683 4,299 488,093 Investment Securities Held-to-Maturity 60,310 - 35,400 25,754 61,154 Loans & Leases, Net of Deferred Fees & Allowance 2,543,773 - - 2,527,799 2,527,799 Accrued Interest Receivable 15,688 - 15,688 - 15,688 Liabilities: Deposits 3,025,276 2,505,769 517,607 - 3,023,376 Subordinated Debentures 10,310 - 7,431 - 7,431 Accrued Interest Payable 2,465 - 2,465 - 2,465

The shares are primarily held by local residents and are not actively traded. However, trades are reported on the OTCQX under the symbol “FMCB”. On May 14, 2020, the Board of Directors declared a mid-year cash dividend of $7.25 per share, a 2.8% increase over the $7.05 per share paid on June 27, 2019. The cash dividend was paid on July 1, 2020, to shareholders of record on June 12, 2020. Basic earnings per common share amounts are computed by dividing net income by the weighted average number of common shares outstanding for the period. There are no common stock equivalent shares. Therefore diluted and basic earnings per common share are the same. The following table calculates the basic earnings per common share for the three and six months ended June 30, 2020 and 2019.

Leases [Abstract]
Leases	9. Leases Lessee – Operating Leases Operating leases in which we are the lessee are recorded as operating lease right-of-use (“ROU”) assets and operating lease liabilities, included in other assets and other liabilities, respectively, on our consolidated balance sheets. We do not currently have any significant finance leases in which we are the lessee. Operating lease ROU assets represent our right to use an underlying asset during the lease term and operating lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and operating lease liabilities are recognized at lease commencement based on the present value of the remaining lease payments using a discount rate that represents our incremental borrowing rate at the lease commencement date. ROU assets are further adjusted for lease incentives. Operating lease expense, which is comprised of amortization of the ROU asset and the implicit interest accreted on the operating lease liability, is recognized on a straight-line basis over the lease term, and is recorded net in occupancy expense in the consolidated statements of income. Our leases relate primarily to office space and bank branches with remaining lease terms of generally 1 to 10 years. Certain lease arrangements contain extension options which typically range from 5 to 10 years at the then fair market rental rates. ASC 842 requires lessees to evaluate whether option periods, if available, will be exercised in order to determine the full life of the lease. The Company used the first option period, unless it is a relatively new lease that has a long initial lease term or other extenuating circumstances. As of June 30, 2020, operating lease ROU assets and liabilities were $4.64 million and $4.71 million, respectively. As of June 30, 2019, operating lease ROU assets and liabilities were $5.31 million and $5.34 million, respectively. As of December 31, 2019, operating lease ROU assets and liabilities were $4.98 million and $5.03 million, respectively.

Lessor - Direct Financing Leases The Company is the lessor in direct finance lease arrangements. Leases are recorded at the principal balance outstanding, net of unearned income and charge-offs. Interest income is recognized using the interest method. Leases typically have a maturity of three Lease payments due to the Company are typically fixed and paid in equal installments over the lease term. Variable lease payments that do not depend on an index or a rate (e.g., property taxes) that are paid directly by the Company are minimal. The majority of property taxes are paid directly by the client to a third party and are not considered part of variable payments and therefore are not recorded by the Company. As a lessor, the Company leases certain types of agriculture equipment, solar equipment, construction equipment and other equipment to its customers. The Company's net investment in direct financing leases was $104.1 million at June 30, 2020, $107.3 million at December 31, 2019 and $103.3 million at June 30, 2019.

Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	10. Recent Accounting Pronouncements Recently Adopted Accounting Guidance The following paragraphs provide descriptions of recently adopted accounting standards that may have had a material effect on the Company’s financial position or results of operations. In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The ASU will require the earlier recognition of credit losses on loans and other financial instruments based on an expected loss model, replacing the incurred loss model that is currently in use. Under the new guidance, an entity will measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. The expected loss model will apply to loans and leases, unfunded lending commitments, held-to-maturity debt securities and other debt instruments measured at amortized cost. The impairment model for available-for-sale debt securities will require the recognition of credit losses through a valuation allowance when fair value is less than amortized cost, regardless of whether the impairment is considered to be other-than-temporary. During 2019, the Company completed an assessment of its CECL data and system needs, and engaged a third-party vendor to assist in developing a CECL model. The Company, in conjunction with this vendor, researched and analyzed modeling standards, loan segmentation, as well as potential external inputs to supplement our historical loss history. Model validation began in the third quarter of 2019, enabling us to complete parallel runs using data beginning with the second quarter of 2019 . The new guidance had been effective on January 1, 2020. However, on March 27, 2020 in response to Congress passing the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”), federal banking regulators issued an interim final rule allowing banks the option of delaying the implementation of CECL until December 31, 2020 or when the coronavirus national emergency ends, whichever comes first. The Company has elected to delay CECL implementation, but continues to run its CECL model quarterly to accumulate data for the ultimate implementation.

Significant Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements and notes thereto have been prepared in accordance with accounting principles generally accepted in the United States of America for financial information. The accompanying consolidated financial statements include the accounts of the Company and the Company’s wholly owned subsidiaries, F & M Bancorp, Inc. and the Bank, along with the Bank’s wholly owned subsidiaries, Farmers & Merchants Investment Corporation and Farmers/Merchants Corp. Significant inter-company transactions have been eliminated in consolidation. The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of the Consolidated Statements of Cash Flows, the Company has defined cash and cash equivalents as those amounts included in the balance sheet captions Cash and Due from Banks, Interest Bearing Deposits with Banks, Federal Funds Sold which have maturity dates of 3 months or less. For these instruments, the carrying amount is a reasonable estimate of fair value.
Investment Securities	Investment Securities Investment securities are classified at the time of purchase as held-to-maturity (“HTM”) if it is management’s intent and the Company has the ability to hold the securities until maturity. These securities are carried at cost, adjusted for amortization of premium to earliest call date and accretion of discount using a level yield of interest over the estimated remaining period until maturity. Losses, reflecting a decline in value judged by the Company to be other than temporary, are recognized in the period in which they occur. Securities are classified as available-for-sale (“AFS”) if it is management’s intent, at the time of purchase, to hold the securities for an indefinite period of time and/or to use the securities as part of the Company’s asset/liability management strategy. These securities are reported at fair value with aggregate unrealized gains or losses excluded from income and included as a separate component of shareholders’ equity, net of related income taxes. Fair values are based on quoted market prices or broker/dealer price quotations on a specific identification basis. Gains or losses on the sale of these securities are computed using the specific identification method. Trading securities, if any, are acquired for short-term appreciation and are recorded in a trading portfolio and are carried at fair value, with unrealized gains and losses recorded in non-interest income. Management evaluates securities for other-than-temporary impairment (“OTTI”) on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss, and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: (1) OTTI related to credit loss, which must be recognized in the income statement; and (2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of a market adjustment is recognized through earnings.
Loans & Leases	Loans & Leases Loans & leases are reported at the principal amount outstanding net of unearned discounts and deferred loan & lease fees and costs. Interest income on loans & leases is accrued daily on the outstanding balances using the simple interest method. Loan & lease origination fees are deferred and recognized over the contractual life of the loan or lease as an adjustment to the yield. Loans & leases are placed on non-accrual status when the collection of principal or interest is in doubt or when they become past due for 90 days or more unless they are both well-secured and in the process of collection. For this purpose, a loan or lease is considered well-secured if it is collateralized by property having a net realizable value in excess of the amount of the loan or lease or is guaranteed by a financially capable party. When a loan or lease is placed on non-accrual status, the accrued and unpaid interest receivable is reversed and charged against current income; thereafter, interest income is recognized only as it is collected in cash. Additionally, cash would be applied to principal if all principal was not expected to be collected. Loans & leases placed on non-accrual status are returned to accrual status when the loans or leases are paid current as to principal and interest and future payments are expected to be made in accordance with the contractual terms of the loan or lease. A loan or lease is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due, including principal and interest, according to the contractual terms of the original agreement. Impaired loans & leases are either: (1) non-accrual loans & leases; or (2) restructured loans & leases that are still accruing interest. Loans or leases determined to be impaired are individually evaluated for impairment. When a loan or lease is impaired, the Company measures impairment based on the present value of expected future cash flows discounted at the loan or lease's effective interest rate, except that as a practical expedient, it may measure impairment based on a loan or lease's observable market price, or the fair value of the collateral if the loan or lease is collateral dependent. A loan or lease is collateral dependent if the repayment of the loan or lease is expected to be provided solely by the underlying collateral. A restructuring of a loan or lease constitutes a troubled debt restructuring (TDR) if the Company for economic or legal reasons related to the borrower’s (the term “borrower” is used herein to describe a customer who has entered into either a loan or lease transaction) financial difficulties grants a more than insignificant concession to the borrower that it would not otherwise consider. Restructured loans & leases typically present an elevated level of credit risk as the borrowers are not able to perform according to the original contractual terms. If the restructured loan or lease was current on all payments at the time of restructure and management reasonably expects the borrower will continue to perform after the restructure, management may keep the loan or lease on accrual. Loans & leases that are on nonaccrual status at the time they become TDR, remain on nonaccrual status until the borrower demonstrates a sustained period of performance, which the Company generally believes to be six Generally, the Company will not restructure loans or leases for borrowers unless: (1) the existing loan or lease is brought current as to principal and interest payments; and (2) the restructured loan or lease can be underwritten to reasonable underwriting standards. If these standards are not met other actions will be pursued (e.g., foreclosure) to collect outstanding loan or lease amounts. After restructure, a determination is made whether the loan or lease will be kept on accrual status based upon the underwriting and historical performance of the restructured credit. On March 27, 2020, the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was signed into law by Congress. The CARES Act provides financial institutions, under specific circumstances, the opportunity to temporarily suspend certain requirements under generally accepted accounting principles related to modifications for a limited period of time to account for the effects of COVID-19. In March 2020, a joint statement was issued by federal and state regulatory agencies, after consultation with the FASB, to clarify that short-term loan modifications, such as payment deferrals, fee waivers, extensions of repayment terms or other insignificant payment delays, are not TDRs if made on a good-faith basis in response to COVID-19 to borrowers who were current prior to any relief. Under this guidance, six months or less is provided as an example of short-term, and current is defined as less than 30 days past due at the time the modification program is implemented. The guidance also provides that these modified loans generally are not classified as nonaccrual during the term of the modification. See “Note 2 – Risks and Uncertainties” for additional information on the CARES Act and the impact of COVID-19 on the Company.
Allowance for Credit Losses	Allowance for Credit Losses The allowance for credit losses is an estimate of probable incurred credit losses inherent in the Company's loan & lease portfolio as of the balance sheet date. The allowance is established through a provision for credit losses, which is charged to expense. Additions to the allowance are expected to maintain the adequacy of the total allowance after credit losses and loan & lease growth. Credit exposures determined to be uncollectible are charged against the allowance. Cash received on previously charged off amounts is recorded as a recovery to the allowance. The overall allowance consists of three primary components: specific reserves related to impaired loans & leases; general reserves for inherent losses related to loans & leases that are not impaired; and an unallocated component that takes into account the imprecision in estimating and allocating allowance balances associated with macro factors. The determination of the general reserve for loans & leases that are collectively evaluated for impairment is based on estimates made by management, to include, but not limited to, consideration of historical losses by portfolio segment, internal asset classifications, qualitative factors that include economic trends in the Company's service areas, industry experience and trends, geographic concentrations, estimated collateral values, the Company's underwriting policies, the character of the loan & lease portfolio, and probable losses inherent in the portfolio taken as a whole. The Company maintains a separate allowance for each portfolio segment (loan & lease type). These portfolio segments include: (1) commercial real estate; (2) agricultural real estate; (3) real estate construction (including land and development loans); (4) residential 1 st The Company assigns a risk rating to all loans & leases and periodically performs detailed reviews of all such loans & leases over a certain threshold to identify credit risks and assess overall collectability. For smaller balance loans & leases, such as consumer and residential real estate, a credit grade is established at inception, and then updated only when the loan or lease becomes contractually delinquent or when the borrower requests a modification. For larger balance loans, management monitors and analyzes the financial condition of borrowers and guarantors, trends in the industries in which borrowers operate and the fair values of collateral securing these loans & leases. These credit quality indicators are used to assign a risk rating to each individual loan or lease. These risk ratings are also subject to examination by independent specialists engaged by the Company. The risk ratings can be grouped into five major categories, defined as follows: Pass – A pass loan or lease is a strong credit with no existing or known potential weaknesses deserving of management's close attention. Special Mention – A special mention loan or lease has potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or lease or in the Company's credit position at some future date. Special mention loans & leases are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification. Substandard – A substandard loan or lease is not adequately protected by the current financial condition and paying capacity of the borrower or the value of the collateral pledged, if any. Loans or leases classified as substandard have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. Well-defined weaknesses include a project's lack of marketability, inadequate cash flow or collateral support, failure to complete construction on time or the project's failure to fulfill economic expectations. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Doubtful – Loans or leases classified doubtful have all the weaknesses inherent in those classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, based on currently known facts, conditions and values, highly questionable or improbable. Loss – Loans or leases classified as loss are considered uncollectible. Once a loan or lease becomes delinquent and repayment becomes questionable, the Company will address collateral shortfalls with the borrower and attempt to obtain additional collateral. If this is not forthcoming and payment in full is unlikely, the Company will estimate its probable loss and immediately charge-off some or all of the balance. The general reserve component of the allowance for credit losses also consists of reserve factors that are based on management's assessment of the following for each portfolio segment: (1) inherent credit risk; (2) historical losses; and (3) other qualitative factors. These reserve factors are inherently subjective and are driven by the repayment risk associated with each portfolio segment described below: Commercial Real Estate – Commercial real estate mortgage loans are generally considered to possess a higher inherent risk of loss than the Company’s commercial, agricultural and consumer loan types. Adverse economic developments or an overbuilt market impact commercial real estate projects and may result in troubled loans. Trends in vacancy rates of commercial properties impact the credit quality of these loans. High vacancy rates reduce operating revenues and the ability for properties to produce sufficient cash flow to service debt obligations. Real Estate Construction – Real estate construction loans, including land loans, are generally considered to possess a higher inherent risk of loss than the Company’s commercial, agricultural and consumer loan types. A major risk arises from the necessity to complete projects within specified cost and time lines. Trends in the construction industry significantly impact the credit quality of these loans, as demand drives construction activity. In addition, trends in real estate values significantly impact the credit quality of these loans, as property values determine the economic viability of construction projects. Commercial – These loans are generally considered to possess a moderate inherent risk of loss because they are shorter-term; typically made to relationship customers; generally underwritten to existing cash flows of operating businesses; and may be collateralized by fixed assets, inventory and/or accounts receivable. Debt coverage is provided by business cash flows and economic trends influenced by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans. Agricultural Real Estate and Agricultural – These loans are generally considered to possess a moderate inherent risk of loss since they are typically made to relationship customers and are secured by crop production, livestock and related real estate. These loans are vulnerable to two risk factors that are largely outside the control of Company and borrowers: commodity prices and weather conditions. Leases – Equipment leases are generally considered to possess a moderate inherent risk of loss. As lessor, the Company is subject to both the credit risk of the borrower and the residual value risk of the equipment. Credit risks are underwritten using the same credit criteria the Company would use when making an equipment term loan. Residual value risk is managed through the use of qualified, independent appraisers that establish the residual values the Company uses in structuring a lease. Residential 1st Mortgages and Home Equity Lines and Loans – These loans are generally considered to possess a lower inherent risk of loss. The degree of risk in residential real estate lending depends primarily on the loan amount in relation to collateral value, the interest rate and the borrower's ability to repay in an orderly fashion. Economic trends determined by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans. Weak economic trends indicate that the borrowers' capacity to repay their obligations may be deteriorating. Consumer & Other – A consumer installment loan portfolio is usually comprised of a large number of small loans scheduled to be amortized over a specific period. Most installment loans are made for consumer purchases. Economic trends determined by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans. Weak economic trends indicate that the borrowers' capacity to repay their obligations may be deteriorating. At least quarterly, the Board of Directors reviews the adequacy of the allowance, including consideration of the relative risks in the portfolio, current economic conditions and other factors. If the Board of Directors and management determine that changes are warranted based on those reviews, the allowance is adjusted. In addition, the Company's and Bank's regulators, including the Federal Reserve Board (“FRB”), the California Department of Business Oversight (“DBO”) and the Federal Deposit Insurance Corporation (“FDIC”), as an integral part of their examination process, review the adequacy of the allowance. These regulatory agencies may require additions to the allowance based on their judgment about information available at the time of their examinations.
Acquired Loans	Acquired Loans Loans acquired through purchase or through a business combination are recorded at their fair value at the acquisition date. Credit discounts, which reflect estimates of credit losses, expected to be incurred over the life of the loan, are included in the determination of fair value; therefore, an allowance for loan losses is not recorded at the acquisition date.
Allowance for Credit Losses on Off-Balance-Sheet Credit Exposures	Allowance for Credit Losses on Off-Balance-Sheet Credit Exposures The Company also maintains a separate allowance for off-balance-sheet commitments. Management estimates anticipated losses using historical data and utilization assumptions. The allowance for off-balance-sheet commitments is included in Interest Payable and Other Liabilities on the Company’s Consolidated Balance Sheet.
Premises and Equipment	Premises and Equipment Premises, equipment, and leasehold improvements are stated at cost, less accumulated depreciation and amortization. Depreciation is computed principally by the straight-line method over the estimated useful lives of the assets. Estimated useful lives of buildings range from 30 to 40 years, and for furniture and equipment from 3 to 7 years. Leasehold improvements are amortized over the lesser of the terms of the respective leases, or their useful lives, which are generally 5 to 10 years. Remodeling and capital improvements are capitalized while maintenance and repairs are charged directly to occupancy expense.
Other Real Estate	Other Real Estate Other real estate, which is included in other assets, is expected to be sold and is comprised of properties no longer utilized for business operations and property acquired through foreclosure in satisfaction of indebtedness. These properties are recorded at fair value less estimated selling costs upon acquisition. Revised estimates to the fair value less cost to sell are reported as adjustments to the carrying amount of the asset, provided that such adjusted value is not in excess of the carrying amount at acquisition. Initial losses on properties acquired through full or partial satisfaction of debt are treated as credit losses and charged to the allowance for credit losses at the time of acquisition. Subsequent declines in value from the recorded amounts, routine holding costs, and gains or losses upon disposition, if any, are included in non-interest expense as incurred. On March 27, 2020 the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was signed into law by Congress. The CARES Act restricts the ability of financial institutions to exercise their foreclosure rights on residential and multi-family properties backed by federally guaranteed mortgage loans. The State of California has gone further and temporarily suspended all residential and commercial foreclosures. The Company is working with its borrowers when they make requests to defer payments on their mortgage loans. See “Note 2 – Risks and Uncertainties” for additional information on the CARES Act and the impact of COVID-19 on the Company.
Income Taxes	Income Taxes The Company uses the liability method of accounting for income taxes. This method results in the recognition of deferred tax assets and liabilities that are reflected at currently enacted income tax rates applicable to the period in which the deferred tax assets or liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. The deferred provision for income taxes is the result of the net change in the deferred tax asset and deferred tax liability balances during the year. This amount combined with the current taxes payable or refundable results in the income tax expense for the current year. The Company follows the standards set forth in the “Income Taxes” topic of the Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”), which clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. This standard prescribes a recognition threshold and measurement standard for the financial statement recognition and measurement of an income tax position taken or expected to be taken in a tax return. It also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. The Company accounts for leases with Investment Tax Credits (ITC) under the deferred method as established in ASC 740-10. ITC are viewed and accounted for as a reduction of the cost of the related assets and presented as deferred income on the Company’s financial statement. The Company accounts for its interest in Low Income Housing Tax Credits (LIHTC) using the cost method as established in ASC 323-740. As an investor, the Company obtains income tax credits and deductions from the operating losses of these tax credit entities. The income tax credits and deductions are allocated to the investors based on their ownership percentages and are recorded as a reduction of income tax expense (or an increase to income tax benefit) and a reduction of federal income taxes payable. When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the accompanying consolidated balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination. For the three and six months ended June 30, 2020 and 2019, the Company has no material uncertain tax positions and recognized no interest or penalties. The Company's policy is to recognize interest and penalties related to income taxes in the provision for income taxes in the Consolidated Statement of Income.
Basic and Diluted Earnings Per Common Share	Basic and Diluted Earnings Per Common Share The Company’s common stock is not traded on any exchange. However, trades are reported on the OTCQX under the symbol "FMCB". The shares are primarily held by local residents and are not actively traded. Basic earnings per common share amounts are computed by dividing net income by the weighted average number of common shares outstanding for the period. There are no common stock equivalent shares. Therefore, diluted and basic earnings per common share are the same. See Note 8 – “Dividends and Basic Earnings Per Common Share” for additional information.
Segment Reporting	Segment Reporting The “Segment Reporting” topic of the FASB ASC requires that public companies report certain information about operating segments. It also requires that public companies report certain information about their products and services, the geographic areas in which they operate, and their major customers. The Company is a holding company for a community bank, which offers a wide array of products and services to its customers. Pursuant to its banking strategy, emphasis is placed on building relationships with its customers, as opposed to building specific lines of business. As a result, the Company is not organized around discernible lines of business and prefers to work as an integrated unit to customize solutions for its customers, with business line emphasis and product offerings changing over time as needs and demands change.
Comprehensive Income	Comprehensive Income The “Comprehensive Income” topic of the FASB ASC establishes standards for the reporting and display of comprehensive income and its components in the financial statements. Other comprehensive income refers to revenues, expenses, gains, and losses that U.S. GAAP recognize as changes in value to an enterprise but are excluded from net income. For the Company, comprehensive income includes net income and changes in fair value of its available-for-sale investment securities.
Loss Contingencies	Loss Contingencies Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there now are such matters that will have a material effect on the consolidated financial statements.
Business Combinations And Related Matters	Business Combinations And Related Matters Business combinations are accounted for under the acquisition method of accounting in accordance with ASC 805, Business Combinations. Under the acquisition method, the acquiring entity in a business combination recognizes 100 percent of the acquired assets and assumed liabilities, regardless of the percentage owned, at their estimated fair values as of the date of acquisition. Any excess of the fair value over the purchase price of net assets and other identifiable intangible assets acquired is recorded as bargain purchase gain. Assets acquired and liabilities assumed from contingencies must also be recognized at fair value, if the fair value can be determined during the measurement period. Results of operations of an acquired business are included in the statement of operations from the date of acquisition. Acquisition-related costs, including conversion charges, are expensed as incurred.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill is determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill that arises from a business combination is periodically evaluated for impairment at the reporting unit level, at least annually. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Core deposit intangible ("CDI") represents the estimated future benefit of deposits related to an acquisition and is booked separately from the related deposits and evaluated periodically for impairment. The CDI asset is amortized on a straight-line method over its estimated useful life of ten years. At June 30, 2020, the future estimated amortization expense for the CDI arising from our past acquisitions is as follows: (in thousands) 2020 2021 2022 2023 2024 Thereafter Total Core Deposit Intangible Amortization $ 312 $ 611 $ 593 $ 573 $ 549 $ 1,688 $ 4,326 We make a qualitative assessment of whether it is more likely than not that the fair value of a reporting unit where goodwill is assigned is less than its carrying amount. If we conclude that it is more likely than not that the fair value is more than its carrying amount, no impairment is recorded. Goodwill is tested for impairment on an interim basis if circumstances change or an event occurs between annual tests that would more likely than not reduce the fair value of the reporting unit below its carrying amount. The qualitative assessment includes adverse events or circumstances identified that could negatively affect the reporting units’ fair value as well as positive and mitigating events. Such indicators may include, among others, a significant change in legal factors or in the general business climate, significant change in our stock price and market capitalization, unanticipated competition, and an action or assessment by a regulator. If the fair value of a reporting unit is less than its carrying amount, an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value is recognized. The loss recognized should not exceed the total amount of goodwill allocated to that reporting unit.

Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	Recently Adopted Accounting Guidance The following paragraphs provide descriptions of recently adopted accounting standards that may have had a material effect on the Company’s financial position or results of operations. In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The ASU will require the earlier recognition of credit losses on loans and other financial instruments based on an expected loss model, replacing the incurred loss model that is currently in use. Under the new guidance, an entity will measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. The expected loss model will apply to loans and leases, unfunded lending commitments, held-to-maturity debt securities and other debt instruments measured at amortized cost. The impairment model for available-for-sale debt securities will require the recognition of credit losses through a valuation allowance when fair value is less than amortized cost, regardless of whether the impairment is considered to be other-than-temporary. During 2019, the Company completed an assessment of its CECL data and system needs, and engaged a third-party vendor to assist in developing a CECL model. The Company, in conjunction with this vendor, researched and analyzed modeling standards, loan segmentation, as well as potential external inputs to supplement our historical loss history. Model validation began in the third quarter of 2019, enabling us to complete parallel runs using data beginning with the second quarter of 2019 . The new guidance had been effective on January 1, 2020. However, on March 27, 2020 in response to Congress passing the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”), federal banking regulators issued an interim final rule allowing banks the option of delaying the implementation of CECL until December 31, 2020 or when the coronavirus national emergency ends, whichever comes first. The Company has elected to delay CECL implementation, but continues to run its CECL model quarterly to accumulate data for the ultimate implementation.
