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, 2015 and 2014, 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 $1,114,000 and $1,026,000, respectively. Securities. held-to-maturity 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 at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not collected for loans that are placed on nonaccrual or loans that are charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all of the principal and interest amounts contractually due are brought current and future payments are reasonably assured. 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 months. This is supplemented by the risks for each portfolio segment. Risk factors impacting loans in each of the portfolio segments include any deterioration of property values, reduced consumer and business spending as a result of unemployment and reduced credit availability, and a lack of confidence in the economy. The historical experience is adjusted for the following qualitative factors: (a) changes in lending policies and procedures, risk selection and underwriting standards; (b) changes in national, regional and local economic conditions that affect the collectability of the loan portfolio; (c) changes in the experience, ability and depth of lending management and other relevant staff; (d) changes in the volume and severity of past due loans, nonaccrual loans or loans classified special mention, substandard, doubtful or loss; (e) quality of loan review and Board of Directors oversight; (f) changes in the nature and volume of the loan portfolio and terms of loans; (g) the existence and effect of any concentrations of credit and changes in the level of such concentrations; (h) changes in collateral dependent loans; and (i) the effect of other external factors, trends or uncertainties that could affect management’s estimate of probable losses, such as competition and industry conditions. Allowance for Loan Losses, Continued. Premises and Equipment. Transfer of Financial Assets. Off-Balance-Sheet Financial Instruments. 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 recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management’s judgment. As of December 31, 2015, management is not aware of any uncertain tax positions that would have a material effect on the Company’s consolidated financial statements. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. The Company recognizes interest and penalties 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. Derivative Financial Instruments. 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. Securities classified within Level 3 include certain asset-backed securities. Impaired Loans. Fair Values of Financial Instruments. Cash and Cash Equivalents. Securities. Loans Held for Sale. Loans. Federal Home Loan Bank Stock. Accrued Interest Receivable. Bank-owned Life Insurance. Deposits. Other Borrowings. Off-Balance-Sheet Instruments. Advertising. Stock Option Compensation. Comprehensive Income. Mortgage Banking Revenue. Recent Accounting Standards Update . Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, Recent Regulatory Developments. 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 to exclude accumulated other comprehensive (loss) income from regulatory capital. As of December 31, 2015, the Bank was well capitalized under the regulatory framework for prompt corrective action. To be categorized as adequately capitalized, the Bank must maintain a minimum Common equity Tier 1 capital ratio, Tier 1 capital ratio, Total capital ratio and Tier 1 leverage ratio as set forth in the table. Management believes, as of December 31, 2015, that the Bank meets all capital adequacy requirements to which it is subject. The Bank’s actual capital amounts and percentages are presented in the table: Actual For Capital Adequacy Purposes For Well Capitalized Purposes Amount Percentage Amount Percentage Amount Percentage As of December 31, 2015: Tier 1 Leverage Capital Ratio $ 23,511 9.48 % $ 9,918 4.00 % $ 12,398 5.00 % Common Equity Tier 1 Risk-based Capital Ratio 23,511 12.79 8,269 4.50 11,945 6.50 Tier 1 Risk-based Capital Ratio 23,511 12.79 11,026 6.00 14,701 8.00 Total Risk-based Capital Ratio 25,810 14.05 14,701 8.00 18,377 10.00 As of December 31, 2014: Tier 1 Capital to Average Assets 19,589 9.52 8,227 4.00 10,284 5.00 Tier 1 Capital to Risk-Weighted Assets 19,589 12.84 6,102 4.00 9,154 6.00 Total Capital to Risk-Weighted Assets 21,498 14.09 12,206 8.00 15,257 10.00

Securities with unrealized losses aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, are as follows (in thousands): Less Than Twelve More Than Twelve Gross Unrealized Losses Fair Value Gross Unrealized Losses Fair Value At December 31, 2015: U.S. Government agency securities $ (9 ) 1,616 $ 0 0 Municipal securities (14 ) 1,620 (40 ) 1,224 Mortgage-backed securities (40 ) 10,803 (50 ) 2,018 $ (63 ) 14,039 $ (90 ) 3,242 At December 31, 2014: U.S. Government agency securities 0 0 (99 ) 5,945 Municipal securities (2 ) 269 (77 ) 3,026 Mortgage-backed securities (47 ) 8,250 (48 ) 1,705 $ (49 ) 8,519 $ (224 ) 10,676 The unrealized losses on twenty-two securities at December 31, 2015 were caused by market conditions. It is expected that the securities would not be settled at a price less than the par value of the investments. Because the decline in fair value is attributable to market conditions and not credit quality, and because the Company has the ability and intent to hold these investments until a market price recovery or maturity, these investments are not considered other-than-temporarily impaired.

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. In these circumstances, the loan is specifically evaluated for potential classification as to special mention, substandard or even charged-off. The Company uses the following definitions for risk ratings: Pass Special Mention Substandard Doubtful Loss At December 31, 2015, there was one loan over thirty days past due, no loans past due ninety days or more but still accruing and two loans on nonaccrual. Age analysis of past-due loans at December 31, 2015 and 2014 is as follows (in thousands): Accruing Loans 30-59 60-89 Greater Total Current Nonaccrual Total At December 31, 2015: Real estate mortgage: Commercial $ 0 0 0 0 57,847 0 57,847 Residential and home equity 0 0 0 0 69,817 0 69,817 Construction 0 0 0 0 17,493 0 17,493 Commercial 0 0 0 0 40,092 137 40,229 Consumer/other 0 0 0 0 3,877 0 3,877 Total $ 0 0 0 0 189,126 137 189,263 At December 31, 2014: Real estate mortgage: Commercial 0 0 0 0 52,661 0 52,661 Residential and home equity 0 0 0 0 51,858 0 51,858 Construction 0 0 0 0 15,876 0 15,876 Commercial 18 0 0 0 30,566 171 30,755 Consumer/other 0 0 0 0 2,877 0 2,877 Total $ 18 0 0 0 153,838 0 154,027 The following summarizes the amount of impaired loans (in thousands): With No Related With an Allowance Recorded Total Recorded Unpaid Recorded Unpaid Related Recorded Unpaid Related At December 31, 2015: Commercial loans $ 0 0 137 137 62 137 137 62 Consumer 0 0 7 7 7 7 7 7 Total $ 0 0 144 144 69 144 144 69 At December 31, 2014: Commercial loans $ 0 0 229 229 92 229 229 92 Consumer 0 0 8 8 6 8 8 6 Total $ 0 0 237 237 98 237 237 98 The average net investment in impaired loans and interest income recognized and received on impaired loans by loan class are as follows (in thousands): Average Interest Interest Year Ended December 31, 2015: Commercial $ 270 12 12 Consumer 7 1 1 Total $ 277 13 13 Year Ended December 31, 2014: Commercial 244 14 14 Consumer 8 1 1 Total $ 252 15 15 There were no loans measured at fair value on a nonrecurring basis at December 31, 2015.

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.

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, 2015, 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.

The associated income tax benefit recognized was $5,000 and $0 for the years ended December 31, 2015 and 2014, 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.

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 dividend 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.

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 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, 2015, that the Bank meets all capital adequacy requirements to which it is subject. As of December 31, 2015, 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.

Organization	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	Use of Estimates.
Principles of Consolidation	Principles of Consolidation.
Cash and Cash Equivalents	Cash and Cash Equivalents. At December 31, 2015 and 2014, 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 $1,114,000 and $1,026,000, respectively.
Securities	Securities. held-to-maturity 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 Held for Sale.
Loans	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 at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not collected for loans that are placed on nonaccrual or loans that are charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all of the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Allowance for Loan Losses	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 months. This is supplemented by the risks for each portfolio segment. Risk factors impacting loans in each of the portfolio segments include any deterioration of property values, reduced consumer and business spending as a result of unemployment and reduced credit availability, and a lack of confidence in the economy. The historical experience is adjusted for the following qualitative factors: (a) changes in lending policies and procedures, risk selection and underwriting standards; (b) changes in national, regional and local economic conditions that affect the collectability of the loan portfolio; (c) changes in the experience, ability and depth of lending management and other relevant staff; (d) changes in the volume and severity of past due loans, nonaccrual loans or loans classified special mention, substandard, doubtful or loss; (e) quality of loan review and Board of Directors oversight; (f) changes in the nature and volume of the loan portfolio and terms of loans; (g) the existence and effect of any concentrations of credit and changes in the level of such concentrations; (h) changes in collateral dependent loans; and (i) the effect of other external factors, trends or uncertainties that could affect management’s estimate of probable losses, such as competition and industry conditions.

Income Taxes	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 recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management’s judgment. As of December 31, 2015, management is not aware of any uncertain tax positions that would have a material effect on the Company’s consolidated financial statements. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. The Company recognizes interest and penalties 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.
Derivative Financial Instruments	Derivative Financial Instruments.
Fair Value Measurements	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:

Recent Regulatory Developments	Recent Regulatory Developments. 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 to exclude accumulated other comprehensive (loss) income from regulatory capital. As of December 31, 2015, the Bank was well capitalized under the regulatory framework for prompt corrective action. To be categorized as adequately capitalized, the Bank must maintain a minimum Common equity Tier 1 capital ratio, Tier 1 capital ratio, Total capital ratio and Tier 1 leverage ratio as set forth in the table. Management believes, as of December 31, 2015, that the Bank meets all capital adequacy requirements to which it is subject.
