[1] The Global Commercial Bank segment includes direct depreciation and amortization of $5.3 million and $3.6 million for the three months ended June 30, 2013 and 2012, respectively, and $10.4 million and $7.0 million for the six months ended June 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.
