(a)
Amounts in table represent recorded investment and exclude loans held for sale. Recorded investment represents the face amount of the loan increased or decreased by applicable accrued interest, net deferred loan fees and costs, and unamortized premium or discount, and reflects direct charge-offs.
(b)
Past due loan amounts exclude PCI, even if contractually past due (or if we do not expect to collect principal or interest in full based on the original contractual terms), as we are currently accreting income over the remaining term of the loans.
(c)
Net of unearned income, net deferred loan fees and costs, and unamortized discounts and premiums.
(d)
Future accretable yield related to PCI loans is not included in the analysis of the loan portfolio.
