Convertible senior
common stock was excluded from the calculation of diluted earnings per share for the year ended December 31, 2012 because it was anti-dilutive. Had the convertible senior common stock been included in the calculation, 121,891 additional shares
would have been included in the diluted weighted average shares of common stock.
