Accounting Policies [Abstract]
Nature of Business and Summary of Significant Accounting Policies	Note 1. Nature of Business and Summary of Significant Accounting Policies (in thousands, except share and per share data) Nature of Business Citizens Holding Company (referred to herein as the “Company”) owns and operates The Citizens Bank of Philadelphia (the “Bank”). In addition to full service commercial banking, the Bank offers title insurance services through its subsidiary, Title Services LLC. As a state bank, the Bank is subject to regulations of the Mississippi Department of Banking and Consumer Finance and the Federal Deposit Insurance Company. The Company is also subject to the regulations of the Federal Reserve. The area served by the Bank is east central Mississippi, along with southern and northern counties of Mississippi and their surrounding areas. Services are provided at multiple branch offices. Risks and Uncertainties The outbreak of COVID-19 COVID-19 COVID-19 Congress, the President, and the Federal Reserve have taken several actions designed to cushion the economic fallout. Most notably, the Coronavirus Aid, Relief and Economic Security (“CARES”) Act was signed into law at the end of March 2020 as an over $2 trillion legislative package. The goal of the CARES Act is to prevent a severe economic downturn through various measures, including direct financial aid to American families and economic stimulus to significantly impacted industry sectors. The package also includes extensive emergency funding for hospitals and providers. In addition to the general impact of COVID-19, The Company’s business is dependent upon the willingness and ability of its employees and customers to conduct banking and other financial transactions. If the global response to contain COVID-19 COVID-19, Financial position and results of operations The Company’s fee income has been, and could continue to be, reduced due to COVID-19. In COVID-19 COVID-19 The Company’s interest income could be reduced due to COVID-19. In COVID-19 Capital and liquidity While the Company believes that it has sufficient capital to withstand an extended economic recession brought about by COVID-19, The Company maintains access to multiple sources of liquidity. If an extended recession caused large numbers of the Company’s deposit customers to withdraw their funds, the Company might become more reliant on volatile or more expensive sources of funding. Wholesale funding markets have remained open to us, but rates for short term funding have recently been volatile. If funding costs are elevated for an extended period of time, it could have an adverse effect on the Company’s net interest margin. Asset valuation Currently, the Company does not expect COVID-19 COVID-19 non-cash Lending operations and accommodations to borrowers In keeping with regulatory guidance to work with borrowers during this unprecedented situation and as outlined in the CARES Act, the Company has been executing a payment deferral program for its commercial lending clients that are adversely affected by the pandemic. Depending on the demonstrated need of the client, the Company is deferring either the full loan payment or the principal component of the loan payment for 60 or 90 days. As of December 31, 2020, the Company had 9 loans with aggregate principal balances totaling $12,258 which were modified under this guidance. In accordance with interagency guidance issued in March 2020, these short-term deferrals are not considered troubled debt restructurings. With the passage of the Paycheck Protection Program (“PPP”), administered by the Small Business Administration (“SBA”), the Company is actively participating in assisting its customers with applications for resources through the program. PPP loans have a two Further, in sensitivity and service to its communities during this unprecedented time, the Company is waiving certain late payments and service charges. Credit The Company is working with customers directly affected by COVID-19. The COVID-19 COVID-19 Basis of Financial Statement Presentation The accounting policies of the Company and its subsidiary conform to generally accepted accounting principles (“GAAP”) in the United States of America and to general practices within the banking industry. The consolidated financial statements of the Company include the accounts of the Bank and its subsidiary (collectively, the “Company”). All significant intercompany transactions have been eliminated in consolidation. Segment Reporting We have determined that all of our lending divisions meet the aggregation criteria of ASC 280, Segment Reporting, since all offer similar products and services, operate with similar processes, have similar customers and are collectively reviewed by the chief operating decision maker. No other services are material for presentation as a separate segment. Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses and the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans. In connection with the determination of the allowance for loan losses and valuation of foreclosed real estate, management obtains independent appraisals for significant properties. While management uses available information to recognize losses on loans and to value foreclosed real estate, future additions to the allowance or adjustments to the valuation may be necessary based on changes in local economic conditions. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses and valuations of foreclosed real estate. Such agencies may require the Company to recognize additions to the allowance or to make adjustments to the valuation based on their judgments about information available to them at the time of their examination. Due to these factors, it is reasonably possible that the allowance for loan losses and valuation of foreclosed real estate may change materially in the near term. Cash, Due from Banks and Interest Bearing Deposits with Other Banks For the purpose of reporting cash flows, cash and due from banks includes cash on hand and demand deposits. Cash flows from loans originated by the Company, deposits, and federal funds purchased and sold are reported net in the statement of cash flows. The Company is required to maintain average reserve balances with the Federal Reserve Bank based on a percentage of deposits. Interest-bearing deposits with other banks mature within one year and are carried at cost. Investment Securities In accordance with the investments topic of the Accounting Standards Codification (“ASC”), securities are classified as “available-for-sale,” “held-to-maturity” Securities Available-for-Sale Securities that are held for indefinite periods of time or used as part of the Company’s asset/liability management strategy and that may be sold in response to interest rate changes, changes in prepayment risk, the need to increase regulatory capital and other similar factors are classified as available-for-sale available-for-sale The Company periodically reviews its securities for impairment based upon a number of factors, including but not limited to, length of time and extent to which the fair value has been less than cost, the likelihood of the security’s ability to recover any decline in its fair value, financial condition of the underlying issuer, ability of the issuer to meet contractual obligations and ability to retain the security for a period of time sufficient to allow for recovery in fair value. Impairments on securities are recognized when management, based on its analysis, deems the impairment to be other-than-temporary. Loans and Allowance for Loan Losses Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal amount outstanding, net of unearned income and an allowance for loan losses. The Company has no loans held-for-sale. Unearned income includes deferred fees net of deferred direct incremental loan origination cost. Unearned income attributable to loans held with a maturity of more than one year is recognized as income or expense over the life of the loan. Unearned discounts on installment loans are recognized as income over the terms of the loans by a method that approximates the interest method. Unearned income and interest on commercial loans are recognized based on the principal amount outstanding. For all other loans, interest is accrued daily on the outstanding balances. For impaired loans, interest is discontinued on a loan when management believes, after considering collection efforts and other factors, that the borrower’s financial condition is such that collection of interest is doubtful. Cash collections on impaired loans are credited to the loan receivable balance, and no interest income is recognized on those loans until the principal balance has been collected. The Company generally discontinues the accrual of interest income when a loan becomes 90 days past due as to principal or interest; however, management may elect to continue the accrual when the estimated net realizable value of collateral is sufficient to cover the principal balance and the accrued interest. Interest income on other nonaccrual loans is recognized only to the extent of interest payments. Upon discontinuance of the accrual of interest on a loan, any previously accrued but unpaid interest is reversed against interest income. A loan is impaired when management determines that it is probable the Company will be unable to collect all contractual principal and interest payments due in accordance with the terms of the loan agreement. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or, as a practical expedient, at the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent. The amount of impairment, if any, and any subsequent changes are included in the allowance for loan losses. Troubled debt restructurings (“TDR”) are those for which concessions have been granted to the borrower due to a deterioration of the borrower’s financial condition. Such concessions may include reduction in interest rates or deferral of interest or principal payments. In evaluating whether to restructure a loan, management analyzes the long-term financial condition of the borrower, including guarantor and collateral support, to determine whether the proposed concessions will increase the likelihood of repayment of principal and interest. TDR are classified as performing, unless they are on nonaccrual status of 90 days or more delinquent, in which case they are considered nonperforming. The allowance for loan losses is established through a provision for loan losses charged against net income. Loans determined to be uncollectible are charged against the allowance for loan losses, and subsequent recoveries, if any, are credited to the allowance. The allowance represents an amount, which, in management’s judgment, will be adequate to absorb estimated probable losses on existing loans that may become uncollectible. In order to determine an adequate level of allowance, management utilizes a model that calculates the allowance for loan loss by applying an average historical charge-off Large groups of small-balance homogenous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer and residential loans for impairment disclosures. Business Combinations, Accounting for Credit-Deteriorated Purchased Loans and Related Assets Business combinations are accounted for by applying the acquisition method in accordance with ASC 805, “Business Combinations.” Under the acquisition method, identifiable assets acquired and liabilities assumed and any non-controlling Loans purchased in business combinations with evidence of credit deterioration since origination and for which it is probable that all contractually required payments will not be collected are considered to be credit-impaired. Purchased credit deteriorated loans are accounted for in accordance with ASC 310-30, 310-30”), Bank Premises, Furniture, Fixtures and Equipment The Company’s premises, furniture, fixtures and equipment are stated at cost less accumulated depreciation computed by straight-line methods over the estimated useful lives of the assets, which range from three Leases ASU 2016-02, 2018-11, Once the Company identifies and determines certain contracts are leases according to FASB ASC Topic 842, the Company classifies it as an operating or a finance lease and recognizes a right-of-use right-of-use The Company’s operating leases primarily consist of building and land leases. The Company recognizes lease rent expense on a straight-line basis over the term of the lease contract and records it as noninterest expense in net occupancy – premises for building and land leases. The Company’s amortization of the right-of-use In order to calculate its right-of-use The Company’s short-term leases primarily include automated teller machines. For short-term leases, the Company recognizes lease expense on a straight-line basis over the lease term. As previously stated, the Company has elected not to include short-term leases on its balance sheet. Other Real Estate Owned Other real estate owned (“OREO”) consists of properties repossessed by the Company on foreclosed loans. These assets are stated at fair value at the date acquired less estimated costs to sell. Losses arising from the acquisition of such property are charged against the allowance for loan losses. Declines in value resulting from subsequent revaluation of the property or losses resulting from disposition of such property are expensed as incurred. Revenue and expenses from operations of other real estate owned are reflected as other income (expense). Cash Surrender Value of Life Insurance The Company has purchased life insurance contracts on certain employees and directors. Certain of such policies were acquired to fund deferred compensation arrangements with employees and directors. The cash surrender value of the Company owned policies is carried at the actual cash surrender value of the policy at the balance sheet date. Changes in the value of the policies are classified in non-interest Intangible Assets Intangible assets include core deposits purchased and goodwill. Core deposit intangibles are amortized on a straight-line basis over their estimated economic lives ranging from 5 Trust Assets Assets held by the trust department of the Company in its fiduciary or agency capacities are not assets of the Company and are not included in the consolidated financial statements. Income Taxes Provisions for income taxes are based on taxes payable or refundable for the current year and the changes in deferred tax assets and liabilities, excluding components of other comprehensive income. Deferred tax assets and liabilities are included in the financial statements at currently enacted income tax rates applicable to the period in which the deferred tax assets and 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. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Comprehensive Income (Loss) Comprehensive income (loss) includes net earnings reported in the consolidated statements of income and changes in unrealized gain (loss) on securities available-for-sale available-for-sale, Net Income Per Share Net income per share-basic is computed by dividing net income by the weighted average number of common shares outstanding during the year. Net income per share-diluted is based on the weighted average number of shares of common stock outstanding for the periods, including the dilutive effect of the Company’s outstanding stock options and restricted stock grants. The effect of the dilutive shares for the years 2020, 2019 and 2018 is illustrated in the following table. 2020 2019 2018 Basic weighted average shares outstanding 5,577,352 5,063,736 4,889,420 Dilutive effect of stock options 2,564 2,367 9,798 Dilutive weighted average shares outstanding 5,579,916 5,066,103 4,899,218 Net income $ 6,931 $ 5,902 $ 6,673 Net income per share-basic $ 1.24 $ 1.17 $ 1.36 Net income per share-diluted $ 1.24 $ 1.17 $ 1.36 Advertising Costs Advertising costs are charged to expense when incurred. Advertising expense was $642, $551 and $640 for the years ended December 31, 2020, 2019 and 2018, respectively. Securities Sold Under Agreements to Repurchase Securities sold under agreements to repurchase are accounted for as collateralized financing transactions and are recorded at the amounts at which the securities were sold. Securities, generally United States Government, federal agency and state county municipal securities, pledged as collateral under these financing arrangements cannot be sold or re-pledged Reclassifications Certain information for 2019 has been reclassified to conform to the financial presentation for 2020. Such reclassifications had no effect on net income or shareholders’ equity. Stock-Based Compensation At December 31, 2020, the Company had outstanding grants under two stock-based compensation plans, which are the 1999 Directors’ Stock Compensation Plan and the 2013 Incentive Compensation Plan. Compensation expense for option grants and restricted stock awards is determined based on the estimated fair value of the stock options and restricted stock on the applicable grant or award date. The Company has elected to account for forfeitures in compensation cost when they occur as permitted under the guidance in ASC 718, “Compensation - Stock Compensation” (“ASC 718”). Expense associated with the Company’s stock-based compensation is included under the line item “Salaries and benefits” on the Consolidated Statements of Income. The Company recognizes compensation expense for all share-based payments to employees in accordance with ASC 718, “Compensation – Stock Compensation.” Subsequent Events The Company has evaluated, for consideration of recognition or disclosure, subsequent events that have occurred through the date of issuance of its financial statements, and has determined that no significant events occurred after December 31, 2020 but prior to the issuance of these financial statements that would have a material impact on its Consolidated Financial Statements. Adoption of New Accounting Standards In January 2017, the FASB issued ASU 2017-04, “Intangibles 2017-04”). ASU 2017-04 two-step 2017-04 ASU 2019-13 2019-13”) 2019-13 2019-13 In March 2020, various regulatory agencies, including the Board of Governors of the Federal Reserve System and the Federal Deposit Insurance Corporation, (“the agencies”) issued an interagency statement on loan modifications and reporting for financial institutions working with customers affected by COVID-19. 310-40, 310-40”), COVID-19 Newly Issued, But Not Yet Effective Accounting Standards In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments 2016-13”). 2016-13 2016-13 2016-13 2016-13 The new effective date for the Company is January 1, 2023.

Business Combinations (dollar amounts in thousands, except share and per share data) Acquisition of Charter Bank Effective October 1, 2019, the Company completed its acquisition of Charter Bank (“Charter”) in a transaction valued at approximately $19,668. The Company issued 666,101 shares of common stock and paid approximately $6,110 to Charter stockholders for 100% voting equity interest in Charter. On October 1, 2019, Charter operated 4 banking locations on the Mississippi Gulf Coast. The Company recorded approximately $10,719 in intangible assets which consist of goodwill of $9,953 and a core deposit intangible of $766. Goodwill resulted from a combination of revenue enhancements from expansion in existing markets and efficiencies resulting from operational synergies. The fair value of the core deposit intangible is being amortized on a straight-line basis over the estimated useful life, currently expected to be 7 years. The Company recorded approximately $558 in expenses related to the merger in 2019. Merger expenses were expensed as incurred and are included in other expense in the consolidated statements of income.

Non Purchased Loans (In Thousands, Except Number of Loans) “Purchased” loans are those acquired in any of the Company’s previous acquisitions. “Non purchased” loans include all of the Company’s other loans. For purposes of this Note 5, all references to “loans” mean non purchased loans. The composition of loans, net at December 31, 2020 and 2019 is as follows: 2020 2019 Real Estate: Land Development and Construction (1) $ 42,677 $ 66,428 Farmland 15,616 15,595 1-4 Family Mortgages 94,280 87,631 Commercial Real Estate 306,875 207,604 Total Real Estate Loans 459,448 377,258 Business Loans: Commercial and Industrial Loans (2) 115,679 84,611 Farm Production and Other Farm Loans 541 683 Total Business Loans 116,220 85,294 Consumer Loans: Credit Cards 1,878 1,833 Other Consumer Loans 10,929 12,060 Total Consumer Loans 12,807 13,893 Total Gross Loans 588,475 476,445 Unearned Income (1 ) (8 ) Allowance for Loan Losses (4,735 ) (3,755 ) Loans, net $ 583,739 $ 472,682 (1) Reclassifications to other loan segments due to changes in loan risk characteristics that occurred in 2020. (2) Includes PPP loans of $29,523 and $-0- as of December 31, 2020 and December 31, 2019, respectively. The Company has certain lending policies and procedures in place that are designed to maximize loan income within an acceptable level of risk. Management reviews these policies and procedures and submits them to the Company’s Board of Directors for its approval when needed, but no less frequently than annually. A reporting system supplements the review process by providing management with frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies and non-performing The Company maintains an independent loan review department that reviews and validates the credit risk program on a periodic basis. Results of this review are presented to management with quarterly reports made to the board of directors. The loan review process complements and reinforces the risk identification and assessment decisions made by the lenders and credit personnel, as well as the Company’s policies and procedures. Loans are made principally to customers in the Company’s market. The Company’s lending policy provides that loans collateralized by real estate are normally made with loan-to-value In the ordinary course of business, the Company has granted loans to certain directors, significant shareholders and their affiliates (collectively referred to as “related parties”). These loans were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other unaffiliated persons and do not involve more than normal risk of collectability. Activity in related party loans during 2020 is presented in the following table.​​​​​​​ Balance outstanding at December 31, 2019 $ 387 Principal additions 690 Principal reductions (231 ) Balance outstanding at December 31, 2020 $ 846 Loans are considered to be past due if the required principal and interest payments have not been received as of the date such payments were due.

In determining which loans to evaluate for impairment, management looks at past due loans, bankruptcy filings and any situation that might lend itself to cause a borrower to be unable to repay the loan according to the original contract terms on those loans in excess of $100. If a loan is determined to be impaired and the collateral is deemed to be insufficient to fully repay the loan, a specific reserve will be established. Interest payments on impaired loans are typically applied to principal unless collectability of the principal amount is reasonably assured, in which case interest is recognized on a cash basis. Impaired loans or portions thereof, are charged-off Impaired loans as of December 31, by class of loans, are as follows: 2020 Unpaid Recorded Recorded Total Related Average Real Estate: Land Development and Construction $ 308 $ 256 $ 52 $ 308 $ 13 $ 210 Farmland 111 111 — 111 — 182 1-4 1,016 1,012 4 1,016 1 928 Commercial Real Estate 6,021 3,323 2,504 5,827 768 7,808 Total Real Estate Loans 7,456 4,702 2,560 7,262 782 9,127 Business: Commercial and Industrial 413 54 359 413 125 279 Total Business Loans 413 54 359 413 125 279 Total Loans $ 7,869 $ 4,756 $ 2,919 $ 7,675 $ 907 $ 9,405 2019 Unpaid Recorded Recorded Total Related Average Real Estate: Land Development and Construction $ 111 $ 58 $ 53 $ 111 $ 16 $ 56 Farmland 252 252 — 252 — 261 1-4 839 740 99 839 28 996 Commercial Real Estate 11,506 5,949 3,840 9,789 566 9,337 Total Real Estate Loans 12,708 6,999 3,992 10,991 610 10,649 Business: Commercial and Industrial 144 — 144 144 72 72 Total Business Loans 144 — 144 144 72 72 Total Loans $ 12,852 $ 6,999 $ 4,136 $ 11,135 $ 682 $ 10,721 The Company did not have any new troubled debt restructurings as of December 31, 2020, 2019, and 2018, respectively.

The Company utilizes a risk grading matrix to assign a risk grade to each of its loans when originated and is updated as factors related to the strength of the loan changes. Loans are graded on a scale of 1 to 9. A description of the general characteristics of the 9 risk grades is as follows. Grade 1. MINIMAL RISK - These loans are without loss exposure to the Company. This classification is reserved for only the best, well secured loans to borrowers with significant capital strength, low leverage, stable earnings and growth and other readily available financing alternatives. This type of loan would also include loans secured by a program of the government. Grade 2. MODEST RISK - These loans include borrowers with solid credit quality and moderate risk of loss. These loans may be fully secured by certificates of deposit with another reputable financial institution, or secured by readily marketable securities with acceptable margins. Grade 3. AVERAGE RISK - This is the rating assigned to most of the loans held by the Company. This includes loans with average loss exposure and average overall quality. These loans should liquidate through possessing adequate collateral and adequate earnings of the borrower. In addition, these loans are properly documented and are in accordance with all aspects of the current loan policy. Grade 4. ACCEPTABLE RISK - Borrower generates sufficient cash flow to fund debt service but most working asset and capital expansion needs are provided from external sources. Profitability and key balance sheet ratios are usually close to peers but one or more may be higher than peers. Grade 5. MANAGEMENT ATTENTION - Borrower has significant weaknesses resulting from performance trends or management concerns. The financial condition of the borrower has taken a negative turn and may be temporarily strained. Cash flow is weak but cash reserves remain adequate to meet debt service. Management weakness is evident. Grade 6. OTHER LOANS ESPECIALLY MENTIONED (“OLEM”) - Loans in this category are fundamentally sound but possess some weaknesses. OLEM loans have potential weaknesses, which may, if not checked or corrected, weaken the asset or inadequately protect the Bank’s credit position at some future date. These loans have an identifiable weakness in credit, collateral, or repayment ability but there is no expectation of loss. Grade 7. SUBSTANDARD ASSETS - Assets classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Assets classified as substandard must have a well-defined weakness based upon objective evidence. Assets classified as substandard are characterized by the distinct possibility that the insured institution will sustain some loss if the deficiencies are not corrected. The possibility that liquidation would not be timely requires a substandard classification even if there is little likelihood of total loss. Grade 8. DOUBTFUL - A loan classified as doubtful has all the weaknesses of a substandard classification and the added characteristic that the weakness makes collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable or improbable. The possibility of loss is extremely high, but because of certain important and reasonable specific pending factors that may work to the advantage and strengthening of the asset, its classification as an estimated loss is deferred until its more exact status may be determined. A doubtful classification could reflect the fact that the primary source of repayment is gone and serious doubt exists as to the quality of a secondary source of repayment. Grade 9. LOSS - Loans classified loss are considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the asset has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may occur in the future. Also included in this classification is the defined loss portion of loans rated substandard assets and doubtful assets. These internally assigned grades are updated on a continual basis throughout the course of the year and represent management’s most updated judgment regarding grades at December 31, 2020. The following table details the amount of gross loans by loan grade and class for the year ended December 31, 2020: Satisfactory Special Substandard Doubtful Loss Total Real Estate: Land Development and Construction $ 41,775 $ 120 $ 782 $ — $ — $ 42,677 Farmland 14,801 95 720 — — 15,616 1-4 85,203 3,210 5,867 — — 94,280 Commercial Real Estate 258,339 35,769 12,767 — — 306,875 Total Real Estate Loans 400,118 39,194 20,136 — — 459,448 Business Loans: Commercial and Industrial Loans 109,525 4,409 1,738 — 7 115,679 Farm Production and Other Farm Loans 512 — 20 — 9 541 Total Business Loans 110,037 4,409 1,758 — 16 116,220 Consumer Loans: Credit Cards 1,845 — 33 — — 1,878 Other Consumer Loans 10,820 43 41 25 — 10,929 Total Consumer Loans 12,665 43 74 25 — 12,807 Total Loans $ 522,820 $ 43,646 $ 21,968 $ 25 $ 16 $ 588,475 The following table details the amount of gross loans by loan grade and class for the year ended December 31, 2019: Satisfactory 1,2,3,4 Special Mention 5,6 Substandard 7 Doubtful 8 Loss 9 Total Loans Real Estate: Land Development and Construction $ 64,112 $ 1,682 $ 634 $ — $ — $ 66,428 Farmland 14,533 331 731 — — 15,595 1-4 Family Mortgages 79,068 1,917 6,646 — — 87,631 Commercial Real Estate 169,270 21,266 17,068 — — 207,604 Total Real Estate Loans 326,983 25,196 25,079 — — 377,258 Business Loans: Commercial and Industrial Loans 80,289 128 4,194 — — 84,611 Farm Production and Other Farm Loans 669 — 4 — 10 683 Total Business Loans 80,958 128 4,198 — 10 85,294 Consumer Loans: Credit Cards 1,770 — 63 — — 1,833 Other Consumer Loans 11,907 59 53 41 — 12,060 Total Consumer Loans 13,677 59 116 41 — 13,893 Total Loans $ 421,618 $ 25,383 $ 29,393 $ 41 $ 10 $ 476,445

Accounts and Financing Receivable, after Allowance for Credit Loss, Noncurrent [Abstract]
Allowance for Loan Losses	Note 7. Allowance for Loan Losses (in thousands) The allowance for loan losses is a reserve established through a provision for possible loan losses charged to expense, which represents management’s best estimate of probable losses that will occur within the existing portfolio of loans. The allowance, in the judgment of management, is necessary to reserve for estimated loan losses and risks inherent in the loan portfolio. The allowance on the majority of the loan portfolio is calculated using a historical chargeoff percentage applied to the current loan balances by loan segment. This historical period is the average of the previous five years with the most current years weighted to show the effect of the most recent chargeoff activity. This percentage is also adjusted for economic factors such as unemployment and general business conditions, both local and nationwide. The group of loans that are considered to be impaired are individually evaluated for possible loss and a specific reserve is established to cover any loss contingency. Loans that are determined to be a loss with no benefit of remaining in the portfolio are charged off to the allowance. These specific reserves are reviewed periodically for continued impairment and adequacy of the specific reserve and adjusted when necessary. The following table details activity in the allowance for loan losses by portfolio segment for the years ended December 31: 2020 Real Business Consumer Total Beginning Balance $ 3,075 $ 371 $ 309 $ 3,755 Provision for loan losses 1,072 422 (9 ) 1,485 Chargeoffs 384 229 104 717 Recoveries 122 47 43 212 Net chargeoffs 262 182 61 505 Ending Balance $ 3,885 $ 611 $ 239 $ 4,735 Period end allowance allocated to: Loans individually evaluated for impairment $ 782 $ 125 $ — $ 907 Loans collectively evaluated for impairment 3,103 486 239 3,828 Ending Balance $ 3,885 $ 611 $ 239 $ 4,735 2019 Real Business Consumer Total Beginning Balance $ 2,845 $ 222 $ 305 $ 3,372 Provision for loan losses 231 247 95 573 Chargeoffs 115 107 138 360 Recoveries 114 9 47 170 Net chargeoffs 1 98 91 190 Ending Balance $ 3,075 $ 371 $ 309 $ 3,755 Period end allowance allocated to: Loans individually evaluated for impairment $ 610 $ 72 $ — $ 682 Loans collectively evaluated for impairment 2,465 299 309 3,073 Ending Balance $ 3,075 $ 371 $ 309 $ 3,755 2018 Real Business Consumer Total Beginning Balance $ 2,151 $ 347 $ 521 $ 3,019 Provision for (reversal of) loan losses 606 (113 ) (159 ) 334 Chargeoffs 223 19 145 387 Recoveries 311 7 88 406 Net chargeoffs (88 ) 12 57 (19 ) Ending Balance $ 2,845 $ 222 $ 305 $ 3,372 Period end allowance allocated to: Loans individually evaluated for impairment $ 401 $ — $ — $ 401 Loans collectively evaluated for impairment 2,444 222 305 2,971 Ending Balance $ 2,845 $ 222 $ 305 $ 3,372 The Company’s recorded investment in loans as of December 31, 2020 and 2019 related to each balance in the allowance for possible loan losses by portfolio segment and disaggregated on the basis of the Company’s impairment methodology was as follows: 2020 Real Estate Business Consumer Total Loans individually evaluated for impairment $ 7,262 $ 413 $ — $ 7,675 Loans collectively evaluated for impairment 506,368 124,128 13,748 644,244 Acquired with deteriorated credit quality 33 305 — 338 $ 513,663 $ 124,846 $ 13,748 $ 652,257 2019 Real Estate Business Consumer Total Loans individually evaluated for impairment $ 10,991 $ 144 $ — $ 11,135 Loans collectively evaluated for impairment 449,138 100,187 15,866 565,191 Acquired with deteriorated credit quality 749 — — 749 $ 460,878 $ 100,331 $ 15,866 $ 577,075 Net chargeoffs (recoveries), segregated by class of loans, were as follows: 2020 2019 2018 Real Estate: Land Development and Construction $ (6 ) $ (18 ) $ 56 Farmland — — 3 1-4 Family Mortgages 243 32 51 Commercial Real Estate 25 (13 ) (198 ) Total Real Estate Loans 262 1 (88 ) Business Loans: Commercial and Industrial Loans 182 98 12 Total Business Loans 182 98 12 Consumer Loans: Credit Cards 39 34 36 Other Consumer Loans 22 57 21 Total Consumer Loans 61 91 57 Total Net Chargeoffs (Recoveries) $ 505 $ 190 $ (19 )

Related Party Transactions [Abstract]
Related Party Transactions	Note 15. Related Party Transactions (in thousands) The Company had, and may have in the future, banking transactions in the ordinary course of business with directors, significant shareholders, principal officers, their immediate families, and affiliated companies in which they are principal shareholders (commonly referred to as related parties). In management’s opinion, such loans are made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with unrelated parties, and do not involve more than the normal risk of collectability at the time of the transaction. Activity in related party loans is detailed in tabular form in Note 5 of the notes to the Financial Statements. Deposits from related parties at December 31, 2020 and December 31, 2019 approximated $7,190 and $5,406, respectively.

Off-Balance Sheet Financial Instruments, Commitments and Contingencies and Concentrations of Risks	Note 16. Off-Balance (in thousands) Commitments to Extend Credit In the ordinary course of business, the Company makes various commitments and incurs certain contingent liabilities to fulfill the financing needs of its customers. These commitments and contingent liabilities include commitments to extend credit and issue standby letters of credit. They involve, to varying degrees, elements of credit risk in excess of the amount recognized in the balance sheets. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. At December 31, 2020 and December 31, 2019, commitments related to unused lines of credit were $138,185 and $94,009, respectively, and standby letters of credit were $4,565 and $2,436, respectively. The fair value of such commitments is not materially different than stated values. As some of these commitments are expected to expire without being drawn upon, the total commitment amount does not necessarily represent future cash requirements. The Company applies the same credit policies and standards as it does in the lending process when making these commitments. The collateral obtained is based upon the assessed credit worthiness of the borrower. Collateral held varies, but may include accounts receivable, crops, livestock, inventory, property and equipment, residential real estate and income-producing commercial properties. Interest Rate Risk The Company is principally engaged in providing short-term and medium-term installment, commercial and agricultural loans with interest rates that are fixed or fluctuate with the prime lending rate. These assets are primarily funded through short-term demand deposits and long-term certificates of deposit with variable and fixed rates. Accordingly, the Company is exposed to interest rate risk because in changing interest rate environments interest rate adjustments on assets and liabilities may not occur at the same time or in the same amount. The Company manages the overall rate sensitivity and mix of its asset and liability portfolio and attempts to minimize the effects that interest rate fluctuations will have on its net interest margin. Legal Proceedings We are a party to various legal proceedings such as claims and lawsuits arising in the course of our normal business activities. Although the ultimate outcome of all claims and lawsuits outstanding as of December 31, 2020 cannot be ascertained at this time, it is the opinion of management that these matters, when resolved, will not have a material adverse effect on our business, results of operations or financial condition. Concentration of Risk The Company makes commercial, residential and consumer loans throughout the state of Mississippi. A substantial portion of the customers’ abilities to honor their contracts is dependent on their business and the agricultural economy in the state. Although the Company’s loan portfolio is diversified, there is a relationship in this state and our operating regions between the agricultural economy and the economic performance of loans made to nonagricultural customers. The Company’s lending policies for agricultural and nonagricultural customers require loans to be well-collateralized and supported by cash flows. Credit losses from loans related to the agricultural economy are consistent with credit losses experienced in the portfolio as a whole. The concentration of credit in the regional agricultural economy is taken into consideration by management in determining the allowance for loan losses. See Note 5 for a summary of loans by type.

Postemployment Benefits [Abstract]
Benefit Plans	Note 17. Benefit Plans (in thousands) The Company provides its employees with a profit sharing and savings plan, which allows employees to direct a percentage of their compensation into a tax deferred retirement account, subject to statutory limitations. To encourage participation, the Company provides a 50 percent matching contribution for up to a maximum of 3 percent of each participant’s compensation, plus discretionary non-matching In connection with the acquisition of Charter, the Company assumed the Charter Bank 401(k) Plan. The plan was terminated by Charter immediately prior to the acquisition where the Charter employees had the choice to rollover their account balance into the Company’s plan, rollover their account balance into another account or take a distribution. The final distribution of account balances has occurred. There was no impact on the Company’s consolidated financial statements as of and for the years ended December 31, 2019 associated with the plan. Deferred Compensation Plans The Company provides a deferred compensation plan covering its directors. Participants in the deferred compensation plan can defer a portion of their compensation for payment after attaining age 70. Life insurance contracts have been purchased which may be used to fund payments under the plan. Expenses related to this plan were $142, $173 and $194 for the plan years ended December 31, 2020, 2019 and 2018, respectively. The Company has also entered into deferred compensation arrangements with certain officers that provide for payments to such officers or their survivors after retirement. Life insurance policies have been purchased that may be used to fund all or a portion of the payments under these arrangements. The obligations of the Company under both the directors and officers deferred compensation arrangements are expensed on a systematic basis over the remaining expected service period of the individual directors and officers. Expenses related to this plan were $607, $586 and $535 for the plan years ended December 31, 2020, 2019 and 2018, respectively.

Banking And Thrift Disclosure [Abstract]
Regulatory Matters	Note 18. Regulatory Matters (in thousands) The Company (on a consolidated basis) and the Bank are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet the minimum regulatory capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material adverse effect on the Company. Under the regulatory capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company must meet specific capital guidelines involving quantitative measures of the Company’s assets, liabilities and certain off-balance The FRB, FDIC and other federal banking agencies have established risk-based capital adequacy guidelines. These guidelines are intended to provide a measure of a bank’s capital adequacy that reflects the degree of risk associated with a bank’s operations. A banking organization’s risk-based capital ratios are obtained by dividing its qualifying capital by its total risk-adjusted assets and off-balance off-balance off-balance The Dodd-Frank Act requires the FRB, the Office of the Comptroller of the Currency (“OCC”) and the FDIC to adopt regulations imposing a continuing “floor” on the risk based capital requirements. In December 2010, the Basel Committee released a final framework for a strengthened set of capital requirements, known as “Basel III”. In July 2013, each of the U.S. federal banking agencies adopted final rules relevant to us: (1) the Basel III regulatory capital reforms; and (2) the “standardized approach of Basel II for non-core Beginning January 1, 2015, the Bank began to comply with the Basel III rules, which became effective on January 1, 2019. Among other things, the Basel III rules impact regulatory capital ratios of banking organizations in the following manner: • Create a new requirement to maintain a ratio of common equity Tier 1 capital to total risk-weighted assets of not less than 4.5%; • Increase the minimum leverage ratio to 4% for all banking organizations (currently 3% for certain banking organizations); • Increase the minimum Tier 1 risk-based capital ratio from 4% to 6%; and • Maintain the minimum total risk-based capital ratio at 8%. In addition, the Basel III rules will subject a banking organization to certain limitations on capital distributions and discretionary bonus payments to executive officers if the organization did not maintain a capital conservation buffer of common equity Tier 1 capital in an amount greater than 2.5% of its total risk-weighted assets. The capital conservation buffer increases the minimum common equity Tier 1 capital ratio to 7%, the minimum Tier 1 risk-based capital ratio to 8.5% and the minimum total risk-based capital ratio to 10.5% for banking organizations seeking to avoid the limitations on capital distributions and discretionary bonus payments to executive officers. The Basel III rules also changed the capital categories for insured depository institutions for purposes of prompt corrective action. Under the rules, to be well capitalized, an insured depository institution must maintain a minimum common equity Tier 1 capital ratio of at least 6.5%, a Tier 1 risk-based capital ratio of at least 8%, a total risk-based capital ratio of at least 10.0%, and a leverage capital ratio of at least 5%. In addition, the Basel III rules established more conservative standards for including an instrument in regulatory capital and imposed certain deductions from and adjustments to the measure of common equity Tier 1 capital. As of December 31, 2020 and 2019, the most recent regulatory notification categorized the Bank as well capitalized. There have been no conditions or events that would cause changes to the capital structure of the Company since this notification. To continue to be categorized as well capitalized under the regulatory framework for prompt corrective action, the Company would have to maintain minimum total risk-based, Tier I risk-based, and Tier I leverage ratios as disclosed below, in comparison with actual capital amounts and ratios:​​​​​​​​​​​​​​ Actual Minimum Capital Minimum Capital Amount Ratio Amount Ratio Amount Ratio December 31, 2020 Citizens Holding Company Tier 1 leverage ratio $ 101,640 7.22 % $ 70,344 5.00 % $ 56,275 4.00 % Common Equity tier 1 capital ratio 101,640 7.22 % 91,448 6.50 % 63,310 4.50 % Tier 1 risk-based capital ratio 101,640 12.55 % 64,780 8.00 % 48,585 6.00 % Total risk-based capital ratio 106,375 13.14 % 80,975 10.00 % 64,780 8.00 % The Citizens Bank of Philadelphia Tier 1 leverage ratio $ 99,170 7.05 % $ 70,326 5.00 % $ 56,261 4.00 % Common Equity tier 1 capital ratio 99,170 7.05 % 91,423 6.50 % 63,293 4.50 % Tier 1 risk-based capital ratio 99,170 12.25 % 64,759 8.00 % 48,569 6.00 % Total risk-based capital ratio 103,905 12.84 % 80,948 10.00 % 64,759 8.00 % December 31, 2019 Citizens Holding Company Tier 1 leverage ratio $ 98,733 8.33 % $ 59,270 5.00 % $ 47,416 4.00 % Common Equity tier 1 capital ratio 98,733 8.33 % 77,051 6.50 % 53,343 4.50 % Tier 1 risk-based capital ratio 98,733 13.86 % 56,972 8.00 % 42,729 6.00 % Total risk-based capital ratio 102,488 14.39 % 71,215 10.00 % 56,972 8.00 % The Citizens Bank of Philadelphia Tier 1 leverage ratio $ 96,824 8.18 % $ 59,206 5.00 % $ 47,365 4.00 % Common Equity tier 1 capital ratio 96,824 8.18 % 76,968 6.50 % 53,285 4.50 % Tier 1 risk-based capital ratio 96,824 13.60 % 56,958 8.00 % 42,719 6.00 % Total risk-based capital ratio 100,579 14.13 % 71,198 10.00 % 56,958 8.00 %

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Note 19. Fair Values of Financial Instruments (in thousands) Under the authoritative guidance on fair value measurements, fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In determining fair value, the Company uses various methods including market, income and cost approaches. Based on these approaches, the Company often utilizes certain assumptions about risk and or the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated, or generally unobservable inputs. The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Based on the observability of the inputs used in the valuation techniques, the Company is required to provide the following information according to the fair value hierarchy. The fair value hierarchy ranks the quality and reliability of the information used to determine fair values. Financial assets and liabilities carried at fair value will be classified and disclosed in one of the three following categories: Level 1 Quoted prices in active markets for identical assets or liabilities; Level 2 Quoted prices in active markets for similar assets and liabilities and inputs that are observable for the asset or liability; or Level 3 Unobservable inputs, such as discounted cash flow models or valuations. The determination of where assets and liabilities fall within this hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company used the following methods and assumptions to estimate the fair value of financial instruments that are measured at fair value on a recurring basis: Investment Securities The fair values of debt securities available for sale are determined by third party matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). The following table presents investment securities that are measured at fair value on a recurring basis as of December 31, 2020: Quoted Prices Significant Significant (Level 1) (Level 2) (Level 3) Totals Securities available for sale Obligations of U.S. Government agencies $ — $ 12,061 $ — $ 12,061 Mortgage-backed securities — 561,983 — 561,983 State, County, Municipals — 104,197 — 104,197 Other securities — 508 — 508 $ — $ 678,749 $ — $ 678,749 The following table presents investment securities that are measured at fair value on a recurring basis as of December 31, 2019: Quoted Prices Significant Significant (Level 1) (Level 2) (Level 3) Totals Securities available for sale Obligations of U.S. Government agencies $ — $ 97,111 $ — $ 97,111 Mortgage-backed securities — 306,900 — 306,900 State, County, Municipals — 60,372.00 — 60,372 $ — $ 464,383 $ — $ 464,383 Impaired Loans Loans considered impaired are reserved for at the time the loan is identified as impaired taking into account the fair value of the collateral less estimated selling costs. Collateral may be real estate and/or business assets including but not limited to, equipment, inventory and accounts receivable. The fair value of real estate is determined based on appraisals by qualified licensed appraisers. The fair value of the business assets is generally based on amounts reported on the business’s financial statements. Appraised and reported values may be adjusted based on management’s historical knowledge, changes in market conditions from the time of valuation and management knowledge of the client and the client’s business. Since not all valuation inputs are observable, these nonrecurring fair value determinations are classified Level 3. The unobservable inputs may vary depending on the individual assets with the fair value of real estate based on appraised value being the predominant approach. The Company reviews the certified appraisals for appropriateness and adjusts the value downward to consider selling, closing and liquidation costs, which typically approximates 25% of the appraised value. Impaired loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly, based on the same factors previously identified. Other real estate owned OREO is primarily comprised of real estate acquired in partial or full satisfaction of loans. OREO is recorded at its estimated fair value less estimated selling and closing costs at the date of transfer, with any excess of the related loan balance over the fair value less expected selling costs charged to the ALLL. Subsequent changes in fair value are reported as adjustments to the carrying amount and are recorded against earnings. The Company outsources the valuation of OREO with material balances to third party appraisers. The Company reviews the third-party appraisal for appropriateness and adjusts the value downward to consider selling and closing costs, which typically approximate 25% of the appraised value. The following table presents assets measured at fair value on a nonrecurring basis during December 31, 2020 and 2019 and were still held at those respective dates: in Active Significant Significant (Level 1) (Level 2) (Level 3) Totals December 31, 2020 Impaired loans $ — $ — $ 2,013 $ 2,013 $ — $ — $ 2,013 $ 2,013 December 31, 2019 Impaired loans $ — $ — $ 4,576 $ 4,576 $ — $ — $ 4,576 $ 4,576 Impaired loans with a carrying value of $2,920 and $5,003 had an allocated allowance for loan losses of $907 and $427 at December 31, 2020 and December 31, 2019, respectively. The allocated allowance is based on the carrying value of the impaired loan and the fair value of the underlying collateral less estimated costs to sell. After monitoring the carrying amounts for subsequent declines or impairment after foreclosure, management determined that no fair value adjustments to OREO was necessary or recorded during the year ended December 31, 2020 and December 31, 2019, respectively.

Stock Based Compensation	Note 20. Stock Based Compensation (in thousands, except share data) The Company has a directors’ stock compensation plan and had an employees’ long-term incentive plan. Under the directors’ plan, the Company may grant options for up to 210,000 shares of common stock. The price of each option is equal to the market price determined as of the option grant date. Options granted are exercisable after six months and expire after 10 years. The employee plan expired on April 13, 2009, no options have been granted since this date and all previously granted options either expired or were exercised as of December 31, 2020. The options previously granted under the employee plan expire 10 years from the grant date. The exercise price is equal to the market price of the Company’s stock on the date of grant. The fair value of each option granted is estimated on the date of the grant using the Black-Sholes option-pricing model. No options were granted in 2020 or 2019, therefore no calculations were required in 2020 or 2019 to determine fair values. The Company has adopted the 2013 Incentive Compensation Plan (the “2013 Plan”), which the Company has used for all equity grants after the adoption and approval of the 2013 Plan. During 2020, the Company’s directors received restricted stock grants totaling 8,250 shares of common stock at a then market value of $20.49 per share and in 2019 received 7,500 shares of common stock at a then market value of $21.53 per share. These grants vest over a o n one-year one-year During 2015, 7,500 shares of restricted stock was granted to the Chief Executive Officer (CEO) that would vest according to a stock performance schedule over the next five years. The stock performance for the Company met the goal for 2016 and the CEO became vested in 20%, or 1,500 shares of the restricted stock at an expense of $32. Again in 2017, the Company met 20% of its goal and the CEO became vested in an additional 1,500 shares of the restricted stock at an expense of $37. The stock performance for the Company did not meet the goal in 2020, 2019 or 2018 and no corresponding expense was recorded. Additionally, the remaining 4,500 shares of restricted stock were forfeited as of June 22, 2020, the expiration of the five-year vesting period. During 2020 and 2019, the Company recorded expense of $167 and $163 related to all of the restricted shares. At December 31, 2020, there were 8,250 shares non-vested Following is a summary of the status of the stock options remaining under the plans for the years ending December 31, 2020, 2019 and 2018: Directors’ Plan Number Weighted Outstanding at January 1, 2018 63,000 $ 20.96 Granted — — Exercised (6,000 ) 18.00 Expired (4,500 ) 18.00 Outstanding at December 31, 2018 52,500 $ 21.55 Granted — — Exercised — — Expired (12,000 ) 21.75 Outstanding at December 31, 2019 40,500 $ 21.49 Granted — — Exercised (7,500 ) 19.26 Expired (13,500 ) 25.72 Outstanding at December 31, 2020 19,500 $ 19.42 Options exercisable at: December 31, 2020 19,500 $ 19.42 The following table presents the outstanding stock options granted in relation to the option price and the weighted average maturity.

Nature of Business	Nature of Business Citizens Holding Company (referred to herein as the “Company”) owns and operates The Citizens Bank of Philadelphia (the “Bank”). In addition to full service commercial banking, the Bank offers title insurance services through its subsidiary, Title Services LLC. As a state bank, the Bank is subject to regulations of the Mississippi Department of Banking and Consumer Finance and the Federal Deposit Insurance Company. The Company is also subject to the regulations of the Federal Reserve. The area served by the Bank is east central Mississippi, along with southern and northern counties of Mississippi and their surrounding areas. Services are provided at multiple branch offices.
Risks and Uncertainties	Risks and Uncertainties The outbreak of COVID-19 COVID-19 COVID-19 Congress, the President, and the Federal Reserve have taken several actions designed to cushion the economic fallout. Most notably, the Coronavirus Aid, Relief and Economic Security (“CARES”) Act was signed into law at the end of March 2020 as an over $2 trillion legislative package. The goal of the CARES Act is to prevent a severe economic downturn through various measures, including direct financial aid to American families and economic stimulus to significantly impacted industry sectors. The package also includes extensive emergency funding for hospitals and providers. In addition to the general impact of COVID-19, The Company’s business is dependent upon the willingness and ability of its employees and customers to conduct banking and other financial transactions. If the global response to contain COVID-19 COVID-19, Financial position and results of operations The Company’s fee income has been, and could continue to be, reduced due to COVID-19. In COVID-19 COVID-19 The Company’s interest income could be reduced due to COVID-19. In COVID-19 Capital and liquidity While the Company believes that it has sufficient capital to withstand an extended economic recession brought about by COVID-19, The Company maintains access to multiple sources of liquidity. If an extended recession caused large numbers of the Company’s deposit customers to withdraw their funds, the Company might become more reliant on volatile or more expensive sources of funding. Wholesale funding markets have remained open to us, but rates for short term funding have recently been volatile. If funding costs are elevated for an extended period of time, it could have an adverse effect on the Company’s net interest margin. Asset valuation Currently, the Company does not expect COVID-19 COVID-19 non-cash Lending operations and accommodations to borrowers In keeping with regulatory guidance to work with borrowers during this unprecedented situation and as outlined in the CARES Act, the Company has been executing a payment deferral program for its commercial lending clients that are adversely affected by the pandemic. Depending on the demonstrated need of the client, the Company is deferring either the full loan payment or the principal component of the loan payment for 60 or 90 days. As of December 31, 2020, the Company had 9 loans with aggregate principal balances totaling $12,258 which were modified under this guidance. In accordance with interagency guidance issued in March 2020, these short-term deferrals are not considered troubled debt restructurings. With the passage of the Paycheck Protection Program (“PPP”), administered by the Small Business Administration (“SBA”), the Company is actively participating in assisting its customers with applications for resources through the program.

Basis of Financial Statement Presentation	Basis of Financial Statement Presentation The accounting policies of the Company and its subsidiary conform to generally accepted accounting principles (“GAAP”) in the United States of America and to general practices within the banking industry. The consolidated financial statements of the Company include the accounts of the Bank and its subsidiary (collectively, the “Company”). All significant intercompany transactions have been eliminated in consolidation.
Segment Reporting	Segment Reporting We have determined that all of our lending divisions meet the aggregation criteria of ASC 280, Segment Reporting, since all offer similar products and services, operate with similar processes, have similar customers and are collectively reviewed by the chief operating decision maker. No other services are material for presentation as a separate segment.
Estimates	Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses and the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans. In connection with the determination of the allowance for loan losses and valuation of foreclosed real estate, management obtains independent appraisals for significant properties. While management uses available information to recognize losses on loans and to value foreclosed real estate, future additions to the allowance or adjustments to the valuation may be necessary based on changes in local economic conditions. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses and valuations of foreclosed real estate. Such agencies may require the Company to recognize additions to the allowance or to make adjustments to the valuation based on their judgments about information available to them at the time of their examination. Due to these factors, it is reasonably possible that the allowance for loan losses and valuation of foreclosed real estate may change materially in the near term.
Cash, Due from Banks and Interest Bearing Deposits with Other Banks	Cash, Due from Banks and Interest Bearing Deposits with Other Banks For the purpose of reporting cash flows, cash and due from banks includes cash on hand and demand deposits. Cash flows from loans originated by the Company, deposits, and federal funds purchased and sold are reported net in the statement of cash flows. The Company is required to maintain average reserve balances with the Federal Reserve Bank based on a percentage of deposits. Interest-bearing deposits with other banks mature within one year and are carried at cost.
Investment Securities	Investment Securities In accordance with the investments topic of the Accounting Standards Codification (“ASC”), securities are classified as “available-for-sale,” “held-to-maturity”
Securities Available-for-Sale	Securities Available-for-Sale Securities that are held for indefinite periods of time or used as part of the Company’s asset/liability management strategy and that may be sold in response to interest rate changes, changes in prepayment risk, the need to increase regulatory capital and other similar factors are classified as available-for-sale available-for-sale The Company periodically reviews its securities for impairment based upon a number of factors, including but not limited to, length of time and extent to which the fair value has been less than cost, the likelihood of the security’s ability to recover any decline in its fair value, financial condition of the underlying issuer, ability of the issuer to meet contractual obligations and ability to retain the security for a period of time sufficient to allow for recovery in fair value. Impairments on securities are recognized when management, based on its analysis, deems the impairment to be other-than-temporary.
Loans and Allowance for Loan Losses	Loans and Allowance for Loan Losses Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal amount outstanding, net of unearned income and an allowance for loan losses. The Company has no loans held-for-sale. Unearned income includes deferred fees net of deferred direct incremental loan origination cost. Unearned income attributable to loans held with a maturity of more than one year is recognized as income or expense over the life of the loan. Unearned discounts on installment loans are recognized as income over the terms of the loans by a method that approximates the interest method. Unearned income and interest on commercial loans are recognized based on the principal amount outstanding. For all other loans, interest is accrued daily on the outstanding balances. For impaired loans, interest is discontinued on a loan when management believes, after considering collection efforts and other factors, that the borrower’s financial condition is such that collection of interest is doubtful. Cash collections on impaired loans are credited to the loan receivable balance, and no interest income is recognized on those loans until the principal balance has been collected. The Company generally discontinues the accrual of interest income when a loan becomes 90 days past due as to principal or interest; however, management may elect to continue the accrual when the estimated net realizable value of collateral is sufficient to cover the principal balance and the accrued interest. Interest income on other nonaccrual loans is recognized only to the extent of interest payments. Upon discontinuance of the accrual of interest on a loan, any previously accrued but unpaid interest is reversed against interest income. A loan is impaired when management determines that it is probable the Company will be unable to collect all contractual principal and interest payments due in accordance with the terms of the loan agreement. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or, as a practical expedient, at the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent. The amount of impairment, if any, and any subsequent changes are included in the allowance for loan losses. Troubled debt restructurings (“TDR”) are those for which concessions have been granted to the borrower due to a deterioration of the borrower’s financial condition. Such concessions may include reduction in interest rates or deferral of interest or principal payments. In evaluating whether to restructure a loan, management analyzes the long-term financial condition of the borrower, including guarantor and collateral support, to determine whether the proposed concessions will increase the likelihood of repayment of principal and interest. TDR are classified as performing, unless they are on nonaccrual status of 90 days or more delinquent, in which case they are considered nonperforming. The allowance for loan losses is established through a provision for loan losses charged against net income. Loans determined to be uncollectible are charged against the allowance for loan losses, and subsequent recoveries, if any, are credited to the allowance. The allowance represents an amount, which, in management’s judgment, will be adequate to absorb estimated probable losses on existing loans that may become uncollectible. In order to determine an adequate level of allowance, management utilizes a model that calculates the allowance for loan loss by applying an average historical charge-off Large groups of small-balance homogenous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer and residential loans for impairment disclosures. Business Combinations, Accounting for Credit-Deteriorated Purchased Loans and Related Assets Business combinations are accounted for by applying the acquisition method in accordance with ASC 805, “Business Combinations.” Under the acquisition method, identifiable assets acquired and liabilities assumed and any non-controlling Loans purchased in business combinations with evidence of credit deterioration since origination and for which it is probable that all contractually required payments will not be collected are considered to be credit-impaired. Purchased credit deteriorated loans are accounted for in accordance with ASC 310-30, 310-30”),
