The Company monitors loan concentrations and evaluates individual customer and aggregate industry leverage, profitability, risk rating distributions, and liquidity for each major standard industry classification segment. At June 30, 2017, one industry segment concentration, the oil and gas industry, constituted more than 10% of the loan portfolio. The Company’s exposure in the oil and gas industry, including related service and manufacturing industries, totaled approximately $208.8 million, or 16.8% of total loans. Additionally, the Company’s exposure to loans secured by commercial real estate is monitored. At June 30, 2017, loans secured by commercial real estate (including commercial construction, farmland and multifamily loans) totaled approximately $531.7 million, 51% of which are secured by owner-occupied commercial properties. Of the $531.7 million in loans secured by commercial real estate, $19.6 million, or 3.7%, were on nonaccrual status at June 30, 2017.

Allowance for Loan Losses

The allowance for loan losses is a valuation account available to absorb probable losses on loans. All losses are charged to the allowance for loan losses when the loss actually occurs or when a determination is made that a loss is likely to occur. Recoveries are credited to the allowance for loan losses at the time of recovery. Quarterly, the probable level of losses in the existing portfolio is estimated through consideration of various factors. Based on these estimates, the allowance for loan losses is increased by charges to earnings and decreased by charge‑offs (net of recoveries).

The allowance is composed of general reserves and specific reserves. General reserves are determined by applying loss percentages to segments of the portfolio. The loss percentages are based on each segment’s historical loss experience, generally over the past twelve to eighteen months, and adjustment factors derived from conditions in the Company’s internal and external environment. All loans considered to be impaired are evaluated on an individual basis to determine specific reserve allocations in accordance with GAAP. Loans for which specific reserves are provided are excluded from the calculation of general reserves.

Loans acquired in business combinations are initially recorded at fair value, which includes an estimate of credit losses expected to be realized over the remaining lives of the loans, and therefore no corresponding allowance for loan losses is recorded for these loans at acquisition. Methods utilized to estimate any subsequently required allowance for loan losses for acquired loans not deemed credit-impaired at acquisition are similar to originated loans; however, the estimate of loss is based on the unpaid principal balance and then compared to any remaining unaccreted purchase discount. To the extent that the calculated loss is greater than the remaining unaccreted purchase discount, an allowance is recorded for such difference.

The Company has an internal loan review department that is independent of the lending function to challenge and corroborate the loan grade assigned by the lender and to provide additional analysis in determining the adequacy of the allowance for loan losses.

Non-Accrual and Past Due Loans

Loans are considered past due if the required principal and interest payment have not been received as of the date such payments were due. Loans are placed on non-accrual status when, in management’s opinion, the probability of collection of interest is deemed insufficient to warrant further accrual. For loans placed on non-accrual status, the accrual of interest is discontinued and subsequent payments received are applied to the principal balance. Interest income is recorded after principal has been satisfied and as payments are received. Non-accrual loans may be returned to accrual status if all principal and interest amounts contractually owed are reasonably assured of repayment within a reasonable period and there is a period of at least six months to one year of repayment performance by the borrower depending on the contractual payment terms.

The amount of interest that would have been recorded on non-accrual loans, had the loans not been classified as non-accrual, totaled approximately $1.7 million and $757,000 for the six months ended June 30, 2017 and 2016, respectively. Interest actually received on non-accrual loans subsequent to their transfer to non-accrual status totaled $195,000 and $59,000 for the six months ended June 30, 2017 and 2016, respectively.

Impaired Loans

Loans are considered impaired when, based upon current information, it is probable the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. All loans classified as special mention, substandard, or doubtful, based on credit risk rating factors, are reviewed to determine whether impairment testing is appropriate. All loan relationships with an outstanding commitment balance above a specified threshold are evaluated for potential impairment. All loan relationships with an outstanding commitment balance below the specified threshold are assigned an allowance allocation percentage that is determined by management and adjusted periodically based on certain factors. An allowance for each impaired loan is calculated based on the present value of expected future cash flows discounted at the loan’s effective interest rate or at the loan’s observable market price or the fair value of the collateral if the loan is collaterally dependent. All impaired loans are reviewed, at a minimum, on a quarterly basis. Existing valuations are reviewed to determine if additional discounts or new appraisals are required. After this review, when comparing the resulting collateral valuation to the outstanding loan balance, if the discounted collateral value exceeds the loan balance no specific allocation is reserved.

Credit Quality

The Company manages credit risk by observing written underwriting standards and lending policy established by the Board of Directors and management to govern all lending activities. The risk management program requires that each individual loan officer review his or her portfolio on a quarterly basis and assign recommended credit ratings on each loan. These efforts are supplemented by independent reviews performed by a loan review officer and other validations performed by the internal audit department. The results of the reviews are reported directly to the Audit Committee of the Board of Directors.

Loans are categorized into risk categories based on relevant information about the ability of borrowers to serve their debt, such as: current financial information, historical payment experience, credit documentation, public information, current economic trends, and other factors. Loans are analyzed individually and classified according to their credit risk. This analysis is performed on a continuous basis. The following definitions are used for risk ratings:

Special Mention: Weakness exists that could cause future impairment, including the deterioration of financial ratios, past due status, and questionable management capabilities. Collateral values generally afford adequate coverage but may not be immediately marketable.

Substandard: Specific and well-defined weaknesses exist that may include poor liquidity and deterioration of financial ratios. Currently the borrower maintains the capacity to service the debt. The loan may be past due and related deposit accounts experiencing overdrafts. Immediate corrective action is necessary.

Doubtful: Specific weaknesses characterized as Substandard exist that are severe enough to make collection in full unlikely. There is no reliable secondary source of full repayment. Loans classified as Doubtful will usually be placed on non-accrual status. The probability of some loss is extremely high but because of certain important and reasonably specific factors, the amount of loss cannot be determined.

Loans not meeting the criteria above that are analyzed individually as part of the above-described process are considered to be Pass rated loans.

The following tables present the classes of loans by risk rating (in thousands):

Troubled Debt Restructurings

A troubled debt restructuring (“TDR”) is a restructuring of a debt made by the Company to a debtor for economic or legal reasons related to the debtor’s financial difficulties that it would not otherwise consider. The Company grants the concession in an attempt to protect as much of its investment as possible.

Information about the Company’s TDRs is as follows (in thousands):

	$	12	$	140	$	25,139	$	25,291

During the three months ended June 30, 2017, there were no loans identified as a TDR, and there were no defaults on any loans that were modified as TDRs during the preceding twelve months. During the three months ended June 30, 2016, there were no loans identified as a TDR, and there were no defaults on any loans that were modified as TDRs during the preceding twelve months. During the six months ended June 30, 2017, there was one loan relationship with a pre-modification balance of $2.0 million identified as a TDR after a reduction in payments. There were no defaults on any loans that were modified as TDRs during the preceding twelve months. During the six months ended June 30, 2016, there was one loan relationship with a pre-modification balance of $5.5 million identified as a TDR after conversion of the loans to interest only for a limited amount of time. This one TDR subsequently defaulted on the modified terms and totaled $5.5 million at June 30, 2016. For purposes of the determination of an allowance for loan losses on these TDRs, as an identified TDR, the Company considers a loss probable on the loan and, as a result is reviewed for specific impairment in accordance with the Company’s allowance for loan loss methodology. If it is determined losses are probable on such TDRs, either because of delinquency or other credit quality indicator, the Company establishes specific reserves for these loans. As of June 30, 2017, there were no commitments to lend additional funds to debtors owing sums to the Company whose terms have been modified in TDRs.
