[1] $1.3 million in subsequently modified TDRs were transferred from accruing TDR classification to accrual status during the period, thus removing the TDR designation. In accordance with ASC 310-40-50-2 “Creditor Disclosure of Troubled Debt Restructurings,” an impaired loan that has been subsequently restructured in a troubled debt restructuring involving modification of terms need not be included in the disclosures in years after the restructuring if both of the following conditions exist: a) the subsequent restructuring agreement specifies an interest rate equal to or greater than the rate that the creditor was willing to accept at the time of the restructuring for a new loan with comparable risk; and b) the loan is not impaired based on the terms specified by the restructuring agreement. During the period ended September 30, 2015, three loans totaling $1.3 million met the conditions stipulated in ASC 310-40-50-2, and after a careful evaluation of well supported documentation by management, these loans were upgraded to accrual status.
