Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(1) Summary of Significant Accounting Policies Organization. The following is a description of the significant accounting policies and practices followed by the Company, which conform to accounting principles generally accepted in the United States of America (“GAAP”) and prevailing practices within the banking industry. Use of Estimates. Principles of Consolidation. Cash and Cash Equivalents. At December 31, 2016 and 2015, the Company was required by law or regulation to maintain cash reserves with the Federal Reserve Bank, in noninterest-bearing accounts with other banks or in the vault in the amounts of $1,799,000 and $1,114,000 respectively. Securities. held-to-maturity available-for-sale. Held-to-maturity Available-for-sale held-to-maturity available-for-sale available-for-sale specific-identification Management evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. Consideration is given to (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. Loans Held for Sale. Loans. pay-off charge-offs, Commitment and loan origination fees are deferred and certain direct origination costs are capitalized. Both are recognized as an adjustment of the yield of the related loan. The accrual of interest on all portfolio classes is discontinued at the time the loan is ninety-days delinquent unless the loan is well collateralized and in process of collection. In all cases, loans are placed on nonaccrual or charged-off charged-off Allowance for Loan Losses. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of specific and general components. The specific component relates to loans that are considered impaired. For such loans, an allowance is established when the discounted cash flows or collateral value of the impaired loan is lower than the carrying value of that loan. The general component covers all other loans and is based on the following factors: The historical loss component of the allowance is determined by losses recognized by portfolio segment over the preceding thirty-six Allowance for Loan Losses, Continued. case-by-case Premises and Equipment. Transfer of Financial Assets. Off-Balance-Sheet off-balance-sheet Income Taxes. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term “more likely than not” means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not more-likely-than-not The Company recognizes interest and penalties on income taxes as a component of income tax expense. The Company files consolidated income tax returns. Income taxes are allocated to the Holding Company and Bank as if separate income tax returns were filed. Fair Value Measurements. Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities that are not active; and model-driven valuations whose inputs are observable or whose significant value drivers are observable. Valuations may be obtained from, or corroborated by, third-party pricing services. Level 3: Unobservable inputs to measure fair value of assets and liabilities for which there is little, if any market activity at the measurement date, using reasonable inputs and assumptions based upon the best information at the time, to the extent that inputs are available without undue cost and effort. The following describes valuation methodologies used for assets measured at fair value: Securities Available for Sale. Impaired Loans. Fair Values of Financial Instruments. Cash and Cash Equivalents. Securities. Loans Held for Sale. Loans. one-to-four Federal Home Loan Bank Stock. Accrued Interest Receivable. Bank-owned Life Insurance. Deposits. Off-Balance-Sheet off-balance-sheet Advertising. Stock-Based Compensation. Comprehensive Income. available-for-sale Mortgage Banking Revenue. Recent Accounting Standards Update.

The Company analyzes loans individually by classifying the loans as to credit risk. Loans classified as substandard or special mention are reviewed quarterly by the Company for further deterioration or improvement to determine if they are appropriately classified and whether there is any impairment. All loans are graded upon initial issuance. Further, construction and nonowner-occupied commercial real estate loans and commercial relationships in excess of $500,000 are reviewed at least annually. The Company determines the appropriate loan grade during the renewal process and reevaluates the loan grade in situations when a loan becomes past due. Loans excluded from the review process above are generally classified as pass credits until: (a) they become past due; (b) management becomes aware of deterioration in the credit worthiness of the borrower; or (c) the client contacts the Company for a modification.

The Company uses the same credit policies in making commitments as it does for on-balance-sheet Commitments to extend credit, construction loans in process and unused lines of credit are agreements to lend to a client as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since some of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each client’s credit worthiness on a case-by-case Guaranteed accounts are irrevocable standby letters of credit issued by us to guarantee a client’s credit line with our third-party credit card company, First Arkansas Bank & Trust. As a part of this agreement, we are responsible for the established credit limit on certain accounts plus 10%. The maximum potential amount of future payments we could be required to make is represented by the dollar amount disclosed in the table below. Standby letters of credit and commitments to extend credit typically result in loans with a market interest rate when funded. In 2016, the Company entered into an agreement with another bank. This agreement references an interest rate swap that was transacted between the other bank and its loan client (the “Counterparty”). Should the Counterparty default on its obligations under the interest rate swap agreement with the other bank, then the Company would be liable for 13.208% of all swap liabilities.

Stock Compensation Plans	(9) Stock Compensation Plans The 2015 Stock Incentive Compensation Plan (the “2015 Plan”) was approved by Shareholders at the Company’s annual meeting of shareholders on May 20, 2015, and permits the Company to grants its key employees and directors stock options, stock appreciation rights, performance shares, and phantom stock. Under the 2015 Plan, the amount of shares which may be issued is 500,000, but in no instance more than 15% of the issued and outstanding shares of the Company’s common stock. As of December 31, 2016, no stock options, stock appreciation rights, performance shares, or phantom stock shares had been issued under the 2015 Plan. As of May 20, 2015, no further grants will be made under the 2007 Stock Option Plan (the “2007 Plan”). Unexercised stock options that were granted under the 2007 Plan will remain outstanding and will expire under the terms of the individual stock grant. A summary of the activity in the Company’s 2007 Stock Option Plan is as follows: Number of Options Weighted- Weighted- Aggregate Outstanding at December 31, 2014 108,400 10.01 Options granted 15,000 12.50 Options exercised (30,540 ) 10.00 Options forfeited (17,360 ) $ 11.44 Outstanding at December 31, 2015 75,500 $ 10.19 Options exercised (25,450 ) 10.29 Options forfeited (7,850 ) 10.00 Outstanding at December 31, 2016 42,200 $ 10.16 2.4 years Exercisable at December 31, 2016 41,000 10.15 2.3 years $ 174,000 At December 31, 2016, there was $1,000 of total unrecognized compensation expense related to nonvested share based compensation arrangements granted under the plan. The cost is expected to be recognized over a weighted-average period of twelve months. The total fair value of shares vesting and recognized as compensation expense was $1,000 and $15,000 in the years ended December 31, 2016 and 2015, respectively. The associated income tax benefit recognized was $0 and $5,000 for the years ended December 31, 2016 and 2015, respectively. The fair value of each option granted during the year ended December 31, 2015 was estimated on the date of grant using the Black-Scholes option-pricing model with the following assumptions: Year Ended December 31, 2015 Weighted average risk-free interest rate 0.89 % Expected dividend yield — Expected stock volatility 8.13 % Expected life in years 3.0 Per share fair value of options issued during the year $ 0.87 The Company used the guidance in Staff Accounting Bulletin No. 107 to determine the estimated life of options issued. Expected volatility is based on volatility of similar companies’ common stock. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The dividend yield is based on the Company’s history and expectation of dividend payouts. In 2012, the Company’s Board of Directors and shareholders adopted the Directors’ Plan. The Directors’ Plan permits the Company’s and the Bank’s directors to elect to receive any compensation to be paid to them in shares of the Company’s common stock. Pursuant to the Directors’ Plan, each director is permitted to make an election to receive shares of stock instead of cash. To encourage directors to elect to receive stock, the Directors’ Plan provides that if a director elects to receive stock, he or she will receive in common stock 110% of the amount of cash fees set by the Board or the Compensation and Nominating Committee. The value of stock to be awarded pursuant to the Directors’ Plan will be the closing price of a share of common stock as traded on the Over-the

Equity [Abstract]
Dividend Restrictions	(13) Dividend Restrictions The Holding Company is limited in the amount of cash dividends it may declare and pay by the amount of dividends it can receive from the Bank. The Bank is limited in the amount of cash dividends that may be paid. The amount of cash dividends that may be paid is based on the Bank’s net earnings of the current year combined with the Bank’s retained earnings of the preceding two years, as defined by state banking regulations. However, for any dividend declaration, the Bank must consider additional factors such as the amount of current period net earnings, liquidity, asset quality, capital adequacy and economic conditions. It is likely that these factors would further limit the amount of dividends which the Bank could declare. In addition, bank regulators have the authority to prohibit banks from paying dividends if they deem such payment to be an unsafe or unsound practice.

Regulatory Matters	(14) Regulatory Matters The Bank is subject to various regulatory capital requirements administered by the banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s and the Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities, and certain off-balance Effective January 1, 2015, the Bank, became subject to the new Basel III capital level threshold requirements under the Prompt Corrective Action regulations with full compliance with all of the final rule’s requirements phased in over a multi-year schedule. These new regulations were designed to ensure that banks maintain strong capital positions even in the event of severe economic downturns or unforeseen losses. Changes that could affect the Bank going forward include additional constraints on the inclusion of deferred tax assets in capital and increased risk weightings for nonperforming loans and acquisition/development loans in regulatory capital. Under the new regulations in the first quarter of 2015, the Bank elected an irreversible one-time opt-out Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and percentage (set forth in the table below) of total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined). Management believes, as of December 31, 2016, that the Bank meets all capital adequacy requirements to which it is subject. As of December 31, 2016, the Bank is well capitalized under the regulatory framework for prompt corrective action. To be categorized as adequately capitalized, the Bank must maintain minimum total risk-based, Tier 1 risk-based, and Tier 1 leverage percentages as set forth in the table. There are no conditions or events since that notification that management believes have changed the Bank’s category.

The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of specific and general components. The specific component relates to loans that are considered impaired. For such loans, an allowance is established when the discounted cash flows or collateral value of the impaired loan is lower than the carrying value of that loan.
