[1] The Global Commercial Bank segment includes direct depreciation and amortization of $5.4 million and $4.9 million for the three months ended September 30, 2014 and 2013, respectively and $15.4 million and $14.0 million for the nine months ended September 30, 2014 and 2013, 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.
