[1] Represents smaller-balance homogeneous loans that are not individually considered impaired and are evaluated based on an analysis of collective borrower performance, key terms of the loans and historical and anticipated trends in defaults and loss severities, and consideration of the unamortized acquisition discount. Includes a provision for loan losses of $2.0 million for newly originated loans acquired during the year ended December 31, 2016.

[2] Represents consumer loan modifications considered to be troubled debt restructurings (“TDRs”) as they provide concessions to borrowers, primarily in the form of interest rate reductions, who are experiencing financial difficulty. As of December 31, 2016, there are $5.3 million in UPB and $4.3 million in carrying value of consumer loans classified as TDRs.

[3] Consumer loans, other than PCD loans, are charged off when available information confirms that loans are uncollectible, which is generally when they become 180 days past due. Charge-offs are presented net of $8.1 million in recoveries of previously charged-off UPB.
