[1] Past due loans include loans on nonaccrual status as of the period indicated. Nonaccrual loans are presented separately in the "Nonaccrual loans" section below.

[2] As discussed in Note 4 to these unaudited consolidated financial statements, the fair value of loans acquired from OMNI and Cameron is preliminary and subject to refinement in subsequent periods. Past due information includes loans acquired from OMNI and Cameron at the gross contractual balance outstanding at June 30, 2011. Inclusion of these loans on a gross basis elevates past due balances compared to December 31, 2010 and compared to the actual carrying balance of these loans.
