The loan portfolio is comprised of four types, commercial and industrial loans, mortgage warehouse, real estate loans and consumer and other loans. The real estate loans are further segregated into owner occupied commercial real estate, commercial real estate, which includes multi-family loans, construction, land and land development, which includes both commercial construction and loans for the construction of residential properties and residential mortgage, which includes first and second liens and home equity lines.  Consumer and other loans includes various types of loans to consumers and overdrafts.  Loans are further separated between loans originated by the Company and loans acquired.
Included in the loans held for investment balance was $13.5 million of net deferred loan origination fees and unamortized premium and discount at both September 30, 2018 and December 31, 2017. Also included in loans at September 30, 2018 and December 31, 2017 was $232 thousand and $1.4 million, respectively, in nonaccretable discount on acquired credit impaired loans. Accrued interest receivable on loans was $10.8 million and $8.8 million at September 30, 2018 and December 31, 2017, respectively. Consumer and other loans include overdrafts of $42 thousand and $48 thousand as of September 30, 2018 and December 31, 2017, respectively.
The loan portfolio consists of various types of loans made to borrowers principally located in the Houston and Dallas metropolitan areas. Although the portfolio is diversified and generally secured by various types of collateral, a substantial portion of its debtors’ ability to honor their obligations is dependent on local economic conditions, including conditions affecting the energy industry. The risks created by this geographic concentration have been considered by management in the determination of the adequacy of the allowance for loan losses. The Company does not have any significant concentration to any one industry or customer. As of September 30, 2018 and December 31, 2017, there were no concentrations of loans related to any single industry in excess of 10% of total loans.
Reserved-based energy loans outstanding represented approximately 0.4% and 0.6% of total funded loans as of September 30, 2018 and December 31, 2017, respectively.  Energy-related service industry loans represented approximately 0.7% and 1.1% of total funded loans as of September 30, 2018 and December 31, 2017, respectively.  As of September 30, 2018, and December 31, 2017, $14.3 million and $19.2 million of reserved-based energy loans and $10.0 million and $17.5 million of energy-related service industry loans were impaired, respectively.

Nonaccrual and Past Due Loans — When management doubts a borrower’s ability to meet payment obligations, which typically occurs when principal or interest payments are more than 90 days past due, the loans are placed on nonaccrual status.

Credit Quality — Internally assigned risk grades for loans are defined as follows:

Grade 1 (Highest Quality — No Apparent Risk) — This category includes loans to borrowers of unquestioned credit standing which are secured by readily marketable collateral of undisputed value, with appropriate margin. It also includes loans to borrowing entities with: excellent capitalization, liquidity and earnings levels; quality management; positive financial trends; and favorable industry conditions.

Grade 2 (Good Quality — Minimal Risk) — This category includes loans to investment grade entities with: good liquidity and financial condition, nominal term debt, strong debt service capability, solid management, and quality financial information. These loans are usually secured with current assets, but may be unsecured. Alternative financing from other lenders is generally available to these borrowers.

Grade 3 (Satisfactory Quality — Acceptable Risk — Tier One) — This category includes loans to entities maintaining fair liquidity and acceptable financial conditions. The level of term debt is moderate, with adequate debt service capability. Earnings may be volatile, but borrowers in this category generally do not show a loss within the last three years. Primary debt service must be supported by identified secondary repayment sources or by guarantors with adequate and proven responsibility and capacity.

Grade 4 (Satisfactory Quality — Acceptable Risk — Tier Two) — This category includes loans to borrowers maintaining acceptable financial conditions; however, borrowers may exhibit certain characteristics of leverage or asset dependency that reflect a greater level of risk than Tier One credits. This category may also include borrowers exhibiting explainable interim losses within the previous three years and/or industry characteristics that warrant frequent monitoring.

Grade 5 (Monitored Loans) — This category includes loans with trends or characteristics which, if continued, could result in impaired repayment ability. The borrower may exhibit a low degree of liquidity and relatively high leverage, erratic earnings history (including the possibility of a reported loss in the past four years), significant term debt and a nominal cushion for debt service capacity. Loans in this category may also include financing to start-up borrowers backed by experienced management and significant capital investment or established companies in distressed industry conditions.

Grade 6 (Other Assets Especially Mentioned) — This category includes loans which have potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or a weakening of the Company’s credit position at some future date. Grade 6 loans are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification.

Grade 7 (Substandard — Accruing) — This category includes loans which are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any, or loans with identified weaknesses but where there is sufficient collateral value and/or cash flow coverage. This category includes loans that: (1)may require a secondary source of repayment (liquidation of collateral or repayment by a guarantor); (2) lack current financial information or appraisals; and/or (3) have collateral deficiencies such that the Company would be in an unsecured position with an obligor not deserving unsecured credit. This category may also include borrowers with operating losses in recent periods.

Grade 8 (Substandard — Nonaccrual) — This category includes loans with the same basic characteristics as Grade 7 loans that also meet the Company’s criteria for nonaccrual status, but do not warrant a Grade 9 or Grade 10 classification.

Grade 9 (Doubtful/Exposure) — This category includes loans with all the Grade 7 or 8 characteristics but with weaknesses that make collection (or liquidation) highly questionable and improbable.

Grade 10 (Loss) — This category includes loans which are considered uncollectible, or of such little value that they should no longer be carried as an asset of the Company.
The credit risk profile of loans aggregated by class and internally assigned risk grades as of the dates set forth were as follows:

Troubled Debt Restructurings — The restructuring of a loan is considered a troubled debt restructuring if both the borrower is experiencing financial difficulties and the creditor has granted a concession. Concessions may include interest rate reductions or below market interest rates, principal forgiveness, restructuring amortization schedules and other actions intended to minimize potential losses.

Troubled debt restructurings identified during the periods indicated were as follows:

The modifications primarily relate to extending the maturity date of the loans, which includes loans modified post-bankruptcy. The Company did not forgive any principal or interest on the restructured loans. For the nine months ended September 30, 2018, the Company did not add any new troubled debt restructuring.  For the nine months ended September 30, 2017, the Company added $9.1 million in new troubled debt restructuring and $8.9 million was outstanding on September 30, 2017

Troubled debt restructurings are individually evaluated for impairment.  The allowance for loan losses included specific reserves of $243 thousand related to $899 thousand of these loans at September 30, 2018.
