The Company categorizes all commercial and commercial real estate loans, except for small business loans, into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation and current economic trends, among other factors. The Company uses the following definitions for risk ratings: Pass: Loans classified as Pass are well protected by the paying capacity and net worth of the borrower. Special Mention: Loans classified as Special Mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the Bank’s credit position at some future date. Substandard: Loans classified as Substandard are inadequately protected by the current net worth and paying capacity of the borrower or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Doubtful: Loans classified as Doubtful have all the weaknesses inherent in those classified as Substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. As of September 30, 2018 and December 31, 2017, and based on the most recent analysis performed, the risk category of loans by loan portfolio segment follows, excluding PCI loans (in thousands) is as follows:
| Pass |  | Special Mention |  | Substandard |  | Doubtful |  | Total

The Company classifies certain loans as troubled debt restructurings when credit terms to a borrower in financial difficulty are modified. The modifications may include a reduction in rate, an extension in term, the capitalization of past due amounts and/or the restructuring of scheduled principal payments. One-to-four family and consumer loans where the borrower’s debt is discharged in a bankruptcy filing are also considered troubled debt restructurings. For these loans, the Bank retains its security interest in the real estate collateral. Included in the non-accrual loan total at September 30, 2018, and December 31, 2017, were $3.6 million and $8.8 million, respectively, of troubled debt restructurings. At September 30, 2018 and December 31, 2017, the Company had no specific reserves allocated to loans that are classified as troubled debt restructurings. Non-accrual loans which become troubled debt restructurings are generally returned to accrual status after six months of performance. In addition to the troubled debt restructurings included in non-accrual loans, the Company also has loans classified as accruing troubled debt restructurings at September 30, 2018, and December 31, 2017, which totaled $24.2 million and $33.3 million, respectively. Troubled debt restructurings are considered in the allowance for loan losses similar to other impaired loans. The following table presents information about troubled debt restructurings which occurred during the three and nine months ended September 30, 2018 and 2017, and troubled debt restructurings modified within the previous year and which defaulted during the three and nine months ended September 30, 2018 and 2017 (dollars in thousands):
