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. Furthermore, construction loans, non-owner 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.

Regulatory Capital	6 Months Ended
	Jun. 30, 2017
Banking and Thrift [Abstract]
Regulatory Capital	(4) Regulatory Capital 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 percentages (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).

Stock Option Plans	(6) Stock Option Plans The 2015 Stock Incentive Compensation Plan (the “2015 Plan”) was approved by the Shareholders at the Company’s annual meeting of shareholders on May 20, 2015 and permits the Company to grant the Company’s key employees and directors stock options, stock appreciation rights, performance shares, and phantom stock. Under the 2015 Plan, the number 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 June 30, 2017, 11,540 stock options have been granted under the 2015 Plan. At June 30, 2017, 453,202 options are available for grant. Number Weighted- Weighted- Aggregate Outstanding at December 31, 2016 — — Granted 11,540 $ 17.03 Outstanding at June 30, 2017 11,540 $ 17.03 4.59 years $ 4,000 Exercisable at June 30, 2017 11,540 $ 17.03 4.59 years $ 4,000 The fair value of shares vested and recognized as compensation expense was $15,000 for the three and six months ended June 30, 2017. There was no share based compensation expense during the three and six months ended June 30, 2016. There was no unrecognized compensation expense related to nonvested share-based compensation arrangements granted under the 2015 Plan. The fair value of each option granted during the six months ended June 30, 2017 was estimated on the date of grant using the Black-Scholes option-pricing model with the following assumptions: Weighted average risk-free interest rate 1.48 % Expected dividend yield 0.40 % Expected stock volatility 8.54 % Expected life in years 3 Per share fair value of options issued during period $ 1.26 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. 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 Weighted- Weighted- Aggregate Outstanding at December 31, 2015 75,500 $ 10.19 Options exercised (3,300 ) 12.27 Options forfeited (7,500 ) 10.00 Outstanding at June 30, 2016 64,700 $ 10.11 Outstanding at December 31, 2016 42,200 $ 10.16 Options exercised (500 ) 10.00 Options forfeited (200 ) 10.00 Outstanding at June 30, 2017 41,500 $ 10.16 1.91 years $ 301,000 Exercisable at June 30, 2017 41,000 $ 10.16 1.87 years $ 297,000 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

Off-Balance Sheet Financial Instruments	(9) Off-Balance The Company is a party to financial instruments with off-balance-sheet interest-rate The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for available lines of credit, construction loans in process and standby letters of credit is represented by the contractual amount of those instruments. 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 Standby letters of credit are written conditional commitments issued by the Company to guarantee the performance of a client to a third party. These letters of credit are primarily issued to support third-party borrowing arrangements and generally have expiration dates within one year of issuance. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to clients. In the event the client does not perform in accordance with the terms of the agreement with the third party, we would be required to fund the commitment. The maximum potential amount of future payments we could be required to make is represented by the contractual amount of the commitment. If the commitment is funded, we would be entitled to seek recovery from the client. Some of the Company’s standby letters of credit are secured by collateral and those secured letters of credit totaled $606,000 at June 30, 2017. 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. The maximum potential credit exposure under this contract at June 30, 2017 is $73,000. The maximum potential amount of future payments we could be required to make for off-balance At June 30, 2017 (in thousands) Commitments to extend credit $ 8,556 Construction loans in process $ 11,717 Unused lines of credit $ 37,956 Standby letters of credit $ 1,676 Guaranteed accounts $ 903
