(a)	Write-offs of PCI loans are recorded against the allowance for loan losses when actual losses for a pool exceed estimated losses that were recorded as purchase accounting adjustments at the time of acquisition. A write-off of PCI loans is recognized when the underlying loan is removed from a pool (e.g., upon liquidation).


(b)	Includes risk-rated loans that have been placed on nonaccrual status and loans that have been modified in a TDR.


(c)	The asset-specific credit card allowance for loan losses is related to loans that have been modified in a TDR; such allowance is calculated based on the loans’ original contractual interest rates and does not consider any incremental penalty rates.


(d)	The prior period amounts have been revised to conform with the current period presentation.
