[1] The Global Commercial Bank segment includes direct depreciation and amortization of $4.5 million and $3.1 million for the three months ended September 30, 2012 and 2011, respectively, and $11.6 million and $8.7 million for the nine months ended September 30, 2012 and 2011, respectively.

[2] The internal reporting model used by management to assess segment performance does not calculate income tax expense by segment. Our effective tax rate is a reasonable approximation of the segment rates.
