[1] Since these loans were already considered classified and/or on nonaccrual status prior to restructuring, the modifications did not have a material effect on the Company’s determination of the allowance for loan losses.

[2] The majority of these modifications do not fit into one separate type, such as rate, term, amount, interest-only or payment, but instead are a combination of multiple types of modifications; therefore, they are disclosed in aggregate.
