Certain investment securities are valued at less than their historical cost. These declines are primarily the result of the rate for these investments yielding less than current market rates, or declines in stock prices of equity securities. Based on evaluation of available evidence, management believes the declines in fair value for these securities are temporary. It is management’s intent to hold the debt securities to maturity or until recovery of the unrealized loss. Should the impairment of any of these debt securities become other than temporary, the cost basis of the investment will be reduced and the resulting loss recognized in net income in the period the other-than-temporary impairment is identified, to the extent the loss is related to credit issues, and to other comprehensive income to the extent the decline on debt securities is related to other factors and the Company does not Certain other investments in debt and equity securities are reported in the financial statements at an amount less than their historical cost.

Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. 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 The allowance consists of allocated and general components. The allocated component relates to loans that are classified as impaired. For those loans that are classified as impaired, 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 nonclassified loans and is based on historical charge-off experience and expected loss given default derived from the Bank’s internal risk rating process. Other adjustments may not A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not Groups of loans with similar risk characteristics are collectively evaluated for impairment based on the group’s historical loss experience adjusted for changes in trends, conditions and other relevant factors that affect repayment of the loans.

All loans are assigned an internal credit quality rating based on an analysis of the borrower’s financial condition. The criteria used to assign quality ratings to extensions of credit that exhibit potential problems or well-defined weaknesses are primarily based upon the degree of risk and the likelihood of orderly repayment, and their effect on the Bank’s safety and soundness. The following are the internally assigned ratings: Pass: This rating represents loans that have strong asset quality and liquidity along with a multi-year track record of profitability. Special mention: This rating represents loans that are currently protected but are potentially weak. The credit risk may Substandard: This rating represents loans that show signs of continuing negative financial trends and unprofitability and therefore, is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Doubtful: This rating represents loans that have all the weaknesses of substandard classified loans with the additional characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. Risk characteristics applicable to each segment of the loan portfolio are described as follows. Real estate-Residential 1 4 1 4 1 4 Real estate-Construction: Construction and land development real estate loans are usually based upon estimates of costs and estimated value of the completed project and include independent appraisal reviews and a financial analysis of the developers and property owners. Sources of repayment of these loans may may Real estate-Commercial: Commercial real estate loans typically involve larger principal amounts, and repayment of these loans is generally dependent on the successful operations of the property securing the loan or the business conducted on the property securing the loan. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Credit risk in these loans may Commercial: The commercial portfolio includes loans to commercial customers for use in financing working capital needs, equipment purchases and expansions. The loans in this category are repaid primarily from the cash flow of a borrower’s principal business operation. Credit risk in these loans is driven by creditworthiness of a borrower and the economic conditions that impact the cash flow stability from business operations. Consumer: The consumer loan portfolio consists of various term and line of credit loans such as automobile loans and loans for other personal purposes. Repayment for these types of loans will come from a borrower’s income sources that are typically independent of the loan purpose. Credit risk is driven by consumer economic factors (such as unemployment and general economic conditions in the Bank’s market area) and the creditworthiness of a borrower.

Cash and cash equivalents, interest-bearing deposits and Federal Home Loan Bank stock The carrying amounts reported in the condensed consolidated balance sheets approximate those assets' fair value. Held-to-maturity securities Fair value is based on quoted market prices, if available. If a quoted market price is not Loans For March 31, 2018, December 31, 2017, Deposits Deposits include demand deposits, savings accounts, NOW accounts and certain money market deposits. The carrying amount approximates fair value. The fair value of fixed-maturity certificates of deposit is estimated by discounting the future cash flows using rates currently offered for deposits of similar remaining maturities. Federal Home Loan Bank advances The fair value of advances is estimated by using rates on debt with similar terms and remaining maturities. Subordinated debentures For these variable rate instruments, the carrying amount is a reasonable estimate of fair value. There is currently a limited market for similar debt instruments and the Company has the option to call the subordinated debentures at an amount close to its par value. Interest payable The carrying amount approximates fair value. Commitments to originate loans, letters of credit and lines of credit The fair value of commitments to originate loans is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present credit worthiness of the counterparties. For fixed-rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair value of letters of credit and lines of credit are based on fees currently charged for similar agreements or on the estimated cost to terminate them or otherwise settle the obligations with the counterparties at the reporting date.
