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.

All loans are underwritten based upon standards set forth in the policies approved by the Company’s Board of Directors. The Company identifies the portfolio segments and classes as follows: Real Estate Mortgage Loans. Commercial. Residential and Home Equity. Construction. Commercial Loans. Additionally, there may be refinancing risk if a commercial loan includes a balloon payment which must be refinanced or paid off at loan maturity. In reference to our risk management process, our commercial loan portfolio presents a higher risk profile than our consumer real estate and consumer loan portfolios. Therefore, we require that all loans to businesses must have a clearly stated and reasonable payment plan to allow for timely retirement of debt, unless secured by liquid collateral or as otherwise justified. Consumer and Other Loans.

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 occupied commercial real estate loans, and commercial loan 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 creditworthiness 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 March 31, 2016, there was one loan past due thirty days or more but still accruing and two loans on nonaccrual.

Regulatory Capital

Regulatory Capital	3 Months Ended
	Mar. 31, 2016
Banking and Thrift [Abstract]
Regulatory Capital	(4) Regulatory Capital Banks are subject to regulatory capital requirements imposed by the Federal Reserve and the FDIC. Until a bank holding company’s assets reach $1 billion, the risk-based capital and leverage guidelines issued by the Federal Reserve are not applied to bank holding companies, unless the bank holding company is engaged in nonbank activities involving significant leverage, or it has a significant amount of outstanding debt held by the general public. Instead, a bank holding company with less than $1 billion in assets generally applies the risk-based capital and leverage capital guidelines on a bank-only basis and must only meet a debt-to-equity ratio at the holding company level. The FDIC risk-based capital guidelines apply directly to insured state banks, regardless of whether they are subsidiaries of a bank holding company. Both agencies’ requirements, which are substantially similar, establish minimum capital ratios in relation to assets, both on an aggregate basis as adjusted for credit risks and off-balance sheet exposures. The risk weights assigned to assets are based primarily on credit risks. A particular asset is assigned to a risk category depending upon its severity of risk. Under the guidelines, capital is compared to the relative risk related to the balance sheet. To derive the risk included in the balance sheet, risk weights (from 0% to 1,250%) are applied to different balance sheet and off-balance sheet assets, primarily based on the relative credit risk of the counterparty. The assignment of risk weightings to certain assets are also subject to qualitative judgments by our regulators. Capital is then classified into three categories, Common Equity Tier 1, Additional Tier 1, and Tier 2. Common Equity Tier 1 Capital (“CET1”) is the sum of common stock instruments and related surplus net of treasury stock, retained earnings, and qualifying minority interests, less applicable regulatory adjustments and deductions that include Accumulated Other Comprehensive Income (“AOCI”). Mortgage-servicing assets, deferred tax assets, and investments in financial institutions are limited to an aggregate of 15% of CET1 and 10% of CET1 individually. Additional Tier 1 Capital includes noncumulative perpetual preferred stock, Tier 1 minority interests, grandfathered trust preferred securities, and Troubled Asset Relief Program instruments, less applicable regulatory adjustments and deductions. Tier 2 Capital includes subordinated debt and preferred stock, total capital minority interests not included in Tier 1, and ALLL not exceeding 1.25% percent of risk-weighted assets, less applicable regulatory adjustments and deductions. Effective January 1, 2015, smaller banks, such as the Bank, became subject to the new Basel III capital level threshold requirements under the FDIC’s Prompt Corrective Action regulations. 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, the Company elected an irreversible one-time opt-out to exclude AOCI from regulatory capital in the first quarter of 2015. The following is a summary at March 31, 2016 of the regulatory capital requirements to be considered “well-capitalized” and the Bank’s capital position.

Off-Balance Sheet Financial Instruments	(9) Off-Balance Sheet Financial Instruments 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 commitments to extend credit, 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 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 creditworthiness 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. A summary of the contractual amounts of the Company’s financial instruments with off-balance-sheet risk at March 31, 2016 are as follows (in thousands): Commitments to extend credit $ 3,413 Construction loans in process $ 10,411 Unused lines of credit $ 27,276 Standby letters of credit $ 1,208 Guaranteed accounts $ 770
