Aging Of The Outstanding Loans And Leases By Class Excluding Loans Impaired At Acquisition Date

The aging of the outstanding non-PCI loans and leases, by class, at September 30, 2015 and December 31, 2014 is provided in the table below.

The calculation of days past due begins on the day after payment is due and includes all days through which all required interest or principal has not been paid. Loans and leases 30 days or less past due are considered current as various grace periods allow borrowers to make payments within a stated period after the due date and still remain in compliance with the loan agreement.
