The Company periodically grants concessions to borrowers experiencing financial difficulties. The Company’s troubled debt restructurings consist primarily of interest rate concessions for periods of three months to thirty years for residential real estate loans, and for periods up to one year for commercial real estate loans.

For the three months ended March 31, 2022 and 2021, respectively, the Company did not enter into any loan modifications meeting the criteria of a troubled debt restructuring.

Management performs a discounted cash flow calculation to determine the amount of valuation reserve required on each of the troubled debt restructurings. Any reserve required is recorded as part of the allowance for loan losses. During the three months ended March 31, 2022 and 2021, there were no material changes to the allowance for loan losses as a result of loan modifications made which were considered a troubled debt restructuring.

During the three months ended March 31, 2022 and 2021, there were no troubled debt restructurings that defaulted (over 30 days past due) within twelve months of the restructure date.

No additional funds are committed to be advanced in connection with troubled debt restructurings.

The Company utilizes an eight-grade internal loan rating system for commercial real estate, construction and commercial and industrial loans, as follows:

Loans rated 1 – 3B are considered “pass” rated loans with low to average risk.

Loans rated 4 are considered “special mention.” These loans are starting to show signs of potential weakness and are being closely monitored by management.

Loans rated 5 are considered “substandard” and are inadequately protected by the current net worth and paying capacity of the obligors and/or the collateral pledged. There is a distinct possibility that the Company will sustain some loss if the weakness is not corrected.

Loans rated 6 are considered “doubtful” and have all the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, highly questionable and improbable.

Loans rated 7 are considered uncollectible (“loss”) and of such little value that their continuance as loans is not warranted.

On an annual basis, or more often if needed, the Company formally reviews the ratings on all commercial real estate, construction and commercial and industrial loans. Annually, the Company engages an independent third party to review a significant portion of loans within these segments. Management uses the results of these reviews as part of its annual review process.
