Reclassifications

Reclassifications: Certain accounts in the consolidated financial statements for 2012 and 2011, as previously presented, have been reclassified to conform to current year classifications.

Securities

We classify debt and equity securities as “held to maturity”, “available for sale” or “trading” according to management’s intent. The appropriate classification is determined at the time of purchase of each security and re-evaluated at each reporting date.

Securities held to maturity – Certain debt securities for which we have the positive intent and ability to hold to maturity are reported at cost, adjusted for amortization of premiums and accretion of discounts. There are no securities classified as held to maturity in the accompanying financial statements.

Securities available for sale - Securities not classified as "held to maturity" or as "trading" are classified as "available for sale." Securities classified as "available for sale" are those securities that we intend to hold for an indefinite period of time, but not necessarily to maturity. "Available for sale" securities are reported at estimated fair value net of unrealized gains or losses, which are adjusted for applicable income taxes, and reported as a separate component of shareholders' equity.

Trading securities - There are no securities classified as "trading" in the accompanying financial statements.

Impairment assessment: Impairment exists when the fair value of a security is less than its cost. Cost includes adjustments made to the cost basis of a security for accretion, amortization and previous other-than-temporary impairments. We perform a quarterly assessment of the debt and equity securities in our investment portfolio that have an unrealized loss to determine whether the decline in the fair value of these securities below their cost is other-than-temporary. This determination requires significant judgment. Impairment is considered other-than-temporary when it becomes probable that we will be unable to recover the cost of an investment. This assessment takes into consideration factors such as the length of time and the extent to which the market values have been less than cost, the financial condition and near term prospects of the issuer including events specific to the issuer or industry, defaults or deferrals of scheduled interest, principal or dividend payments, external credit ratings and recent downgrades, and our intent and ability to hold the security for a period of time sufficient to allow for a recovery in fair value. If a decline in fair value is judged to be other than temporary, the cost basis of the individual security is written down to fair value which then becomes the new cost basis. The amount of the write down is included in other-than-temporary impairment of securities in the consolidated statements of income. The new cost basis is not adjusted for subsequent recoveries in fair value, if any.

Realized gains and losses on sales of securities are recognized on the specific identification method. Amortization of premiums and accretion of discounts are computed using the interest method.

Allowance For Loan Losses

The allowance for loan losses is maintained at a level considered adequate to provide for our estimate of probable credit losses inherent in the loan portfolio. The allowance is increased by provisions charged to operating expense and reduced by net charge-offs. Loans are charged against the allowance for loan losses when we believe that collectability is unlikely. While we use the best information available to make our evaluation, future adjustments may be necessary if there are significant changes in conditions.

The allowance is comprised of three distinct reserve components: (1) specific reserves related to loans individually evaluated, (2) quantitative reserves related to loans collectively evaluated, and (3) qualitative reserves related to loans collectively evaluated. A summary of the methodology we employ on a quarterly basis with respect to each of these components in order to evaluate the overall adequacy of our allowance for loan losses is as follows.

Specific Reserve for Loans Individually Evaluated

First, we identify loan relationships having aggregate balances in excess of $500,000 and that may also have credit weaknesses. Such loan relationships are identified primarily through our analysis of internal loan evaluations, past due loan reports, and loans adversely classified by regulatory authorities. Each loan so identified is then individually evaluated to determine whether it is impaired – that is, based on current information and events, it is probable that we will be unable to collect all amounts due in accordance with the contractual terms of the underlying loan agreement. Substantially all of our impaired loans historically have been collateral dependent, meaning repayment of the loan is expected to be provided solely from the sale of the loan’s underlying collateral. For such loans, we measure impairment based on the fair value of the loan’s collateral, which is generally determined utilizing current appraisals. A specific reserve is established in an amount equal to the excess, if any, of the recorded investment in each impaired loan over the fair value of its underlying collateral, less estimated costs to sell. Our policy is to re-evaluate the fair value of collateral dependent loans at least every twelve months unless there is a known deterioration in the collateral’s value, in which case a new appraisal is obtained.

Quantitative Reserve for Loans Collectively Evaluated

Second, we stratify the loan portfolio into the following ten loan pools: land and land development, construction, commercial, commercial real estate -- owner-occupied, commercial real estate -- non-owner occupied, conventional residential mortgage, jumbo residential mortgage, home equity, consumer, and other. Loans within each pool are then further segmented between (1) loans which were individually evaluated for impairment and not deemed to be impaired, (2) larger-balance loan relationships exceeding $2 million which are assigned an internal risk rating in conjunction with our normal ongoing loan review procedures and (3) smaller-balance homogenous loans.

Quantitative reserves relative to each loan pool are established as follows: for all loan segments detailed above an allocation equaling 100% of the respective pool’s average 12 month historical net loan charge-off rate (determined based upon the most recent twelve quarters) is applied to the aggregate recorded investment in the pool of loans.

Qualitative Reserve for Loans Collectively Evaluated

Third, we consider the necessity to adjust our average historical net loan charge-off rates relative to each of the above ten loan pools for potential risks factors that could result in actual losses deviating from prior loss experience. For example, if we observe a significant increase in delinquencies within the conventional mortgage loan pool above historical trends, an additional allocation to the average historical loan charge-off rate is applied. Such qualitative risk factors considered are: (1) levels of and trends in delinquencies and impaired loans, (2) levels of and trends in charge-offs and recoveries, (3) trends in volume and term of loans, (4) effects of any changes in risk selection and underwriting standards, and other changes in lending policies, procedures, and practice, (5) experience, ability, and depth of lending management and other relevant staff, (6) national and local economic trends and conditions, (7) industry conditions, and (8) effects of changes in credit concentrations.

Premises And Equipment

Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed primarily by the straight-line method for premises and equipment over the estimated useful lives of the assets. The estimated useful lives employed are on average 30 years for premises and 3 to 10 years for furniture and equipment. Repairs and maintenance expenditures are charged to operating expenses as incurred. Major improvements and additions to premises and equipment, including construction period interest costs, are capitalized. No interest was capitalized during 2013, 2012, or 2011.

Securities Sold Under Agreements To Repurchase

Our subsidiary bank is a member of the Federal Home Loan Bank (“FHLB”). Membership in the FHLB makes available short-term and long-term advances under collateralized borrowing arrangements with each subsidiary bank. All FHLB advances are collateralized primarily by similar amounts of residential mortgage loans, certain commercial loans, mortgage backed securities and securities of U. S. Government agencies and corporations. We had $86.1 million available on a short term line of credit with the Federal Reserve Bank at December 31, 2013, which is primarily secured by commercial and industrial loans and consumer loans. We also had $6.0 million available on an unsecured line of credit with a correspondent bank.

Stock Based Compensation

The fair value of our employee stock options granted is estimated at the date of grant using the Black-Scholes option-pricing model. This model requires the input of highly subjective assumptions, changes to which can materially affect the fair value estimate. Additionally, there may be other factors that would otherwise have a significant effect on the value of employee stock options granted but are not considered by the model. Because our employee stock options have characteristics significantly different from those of traded options and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models do not necessarily provide a reliable single measure of the fair value of its employee stock options at the time of grant. There were no options granted in 2013 or 2012.

We recognize compensation expense based on the estimated number of stock awards expected to actually vest, exclusive of the awards expected to be forfeited. During 2011, 2012, and 2013, our stock compensation expense and related deferred taxes were insignificant.

Derivative Financial Instruments

We use derivative instruments primarily to protect against the risk of adverse interest rate movements on the cash flows of certain liabilities. Derivative instruments represent contracts between parties that usually require little or no initial net investment and result in one party delivering cash or another type of asset to the other party based upon a notional amount and an underlying as specified in the contract. A notional amount represents the number of units of a specific item, such as currency units. An underlying represents a variable, such as an interest rate or price index. The amount of cash or other asset delivered from one party to the other is determined based upon the interaction of the notional amount of the contract with the underlying. Derivatives can also be implicit in certain contracts and commitments.

As with any financial instrument, derivative instruments have inherent risks, primarily market and credit risk. Market risk associated with changes in interest rates is managed by establishing and monitoring limits as to the degree of risk that may be undertaken as part of our overall market risk monitoring process. Credit risk occurs when a counterparty to a derivative contract with an unrealized gain fails to perform according to the terms of the agreement. Credit risk is managed by monitoring the size and maturity structure of the derivative portfolio, and applying uniform credit standards to all activities with credit risk.

In accordance with ASC 815, Derivatives and Hedging, all derivative instruments are recorded on the balance sheet at fair value. Changes in the fair value of derivatives are recorded each period in current earnings or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and, if it is, depending on the type of hedge transaction.

Fair-value hedges – For transactions in which we are hedging changes in fair value of an asset, liability, or a firm commitment, changes in the fair value of the derivative instrument are generally offset in the income statement by changes in the hedged item’s fair value.

Cash-flow hedges – For transactions in which we are hedging the variability of cash flows related to a variable-rate asset, liability, or a forecasted transaction, changes in the fair value of the derivative instrument are reported in other comprehensive income. The gains and losses on the derivative instrument, which are reported in comprehensive income, are reclassified to earnings in the periods in which earnings are impacted by the variability of cash flows of the hedged item.

The ineffective portion of all hedges is recognized in current period earnings.

Other derivative instruments – For risk management purposes that do not meet the hedge accounting criteria and, therefore, do not qualify for hedge accounting. These derivative instruments are accounted for at fair value with changes in fair value recorded in the income statement.

We have entered into two forward-starting, pay-fixed/receive LIBOR interest rate swaps. $40 million notional with an effective date of July 18, 2016, was designated as a cash flow hedge of $40 million of forecasted variable rate Federal Home Loan Bank advances. Under the terms of this swap we will pay a fixed rate of 2.98% for a 3 year period. $30 million notional with an effective date of April 18, 2016, was designated as a cash flow hedge of $30 million of forecasted variable rate Federal Home Loan Bank advances. Under the terms of this swap we will pay a fixed rate of 2.89% for a 4.5 year period.
