⁽¹⁾  Loans categorized as special mention exhibit potential weaknesses that require the close attention of management since these potential weaknesses may result in the deterioration of repayment prospects in the future.

⁽²⁾  Loans categorized as substandard exhibit well-defined weaknesses that may jeopardize the liquidation of the debt. These loans continue to accrue interest because they are well secured and collection of principal and interest is expected within a reasonable time.

⁽³⁾  Loans categorized as non-accrual exhibit well-defined weaknesses that may jeopardize the liquidation of the debt or result in a loss if the deficiencies are not corrected.

⁽⁴⁾  Total special mention and substandard loans includes accruing TDRs of $854,000 as of March 31, 2016 and $862,000 as of December 31, 2015.
