[1] The Global Commercial Bank segment includes direct depreciation and amortization of $3.6 million and $2.7 million for the three months ended June 30, 2012 and 2011, respectively, and $7.0 million and $5.6 million for the six months ended June 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.
