[1] The Global Commercial Bank segment includes direct depreciation and amortization of $5.6 million and $4.5 million for the three months ended September 30, 2013 and 2012, respectively, and $16.0 million and $11.6 million for the nine months ended September 30, 2013 and 2012, 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.
