The Company places all commercial loans into various credit risk rating categories based on an assessment of the expected ability of the borrowers to properly service their debt. The assessment considers numerous factors including, but not limited to, current financial information on the borrower, historical payment experience, strength of any guarantor, nature of and value of any collateral, acceptability of the loan structure and documentation, relevant public information and current economic trends. This credit risk rating analysis is performed when the loan is initially underwritten and then annually based on set criteria in the loan policy.

In addition, the Bank has engaged an independent loan review firm to validate risk ratings and to ensure compliance with our policies and procedures. This review of the following types of loans is performed quarterly:

The Company uses the following regulatory definitions for criticized and classified risk ratings:

Special Mention: These loans have a potential weakness that deserves Management’s close attention. If left uncorrected, the potential weaknesses may result in deterioration of the repayment prospects for the loans or of the institution’s credit position at some future date.

Substandard: These loans are inadequately protected by the current net worth and paying capacity of the obligor 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 institution will sustain some loss if the deficiencies are not corrected.

Doubtful: These loans have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full highly questionable and improbable, based on currently existing facts, conditions and values.

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

Loans that are considered to be impaired are individually evaluated for potential loss and allowance adequacy. Loans not deemed impaired are collectively evaluated for potential loss and allowance adequacy.

The table below presents, based on the most recent analysis performed, the risk category of loans by class of loans for December 31, 2018 and 2017.

Troubled Debt Restructurings: The Company has allocated $262 thousand and $423 thousand of specific reserves to customers whose loan terms have been modified in troubled debt restructurings as of December 31, 2018 and December 31, 2017, respectively. There were no unfunded commitments to lend additional amounts to customers with outstanding loans that are classified as troubled debt restructurings.

During the years ended December 31, 2018, 2017 and 2016, the terms of certain loans were modified as troubled debt restructurings. The modification of the terms of such loans included one or a combination of the following: a reduction of the stated interest rate of the loan; or an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk.

The following table presents loans by class modified as troubled debt restructurings that occurred during the year ended December 31, 2018:

The identification of the troubled debt restructured loans did not have a significant impact on the allowance for loan losses. In addition, there were no charge-offs as a result of the classification of these loans as troubled debt restructuring during the years ended December 31, 2018, 2017 and 2016.

There were no payment defaults on loans modified as troubled debt restructurings within twelve months of modification during the year ended December 31, 2018.

The following table presents loans by class modified as troubled debt restructurings during the year ended December 31, 2017 for which there was a payment default during the same period:

The defaults described above did not have a material impact on the allowance for loan losses during 2017 and 2016.

In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under the Company’s internal underwriting policy. The modification of the terms of such loans may include one or more of the following: (1) a reduction of the stated interest rate of the loan to a rate that is lower than the current market rate for new debt with similar risk; (2) an extension of an interest only period for a predetermined period of time; (3) an extension of the maturity date; or (4) an extension of the amortization period over which future payments will be computed. At the time a loan is restructured, the Bank performs a full re-underwriting analysis, which includes, at a minimum, obtaining current financial statements and tax returns, copies of all leases, and an updated independent appraisal of the property. A loan will continue to accrue interest if it can be reasonably determined that the borrower should be able to perform under the modified terms, that the loan has not been chronically delinquent (both to debt service and real estate taxes) or in nonaccrual status since its inception, and that there have been no charge-offs on the loan. Restructured loans with previous charge-offs would not accrue interest at the time of the troubled debt restructuring. At a minimum, six consecutive months of contractual payments would need to be made on a restructured loan before returning it to accrual status. Once a loan is classified as a TDR, the loan is reported as a TDR until the loan is paid in full, sold or charged-off. In rare circumstances, a loan may be removed from TDR status, if it meets the requirements of ASC 310-40-50-2.
