Convertible senior common stock was excluded from the calculation of
diluted earnings per share for the three months ended March 31, 2013 because it was anti-dilutive. Had the convertible senior common stock been included in the calculation, 132,019 additional shares would have been included in the diluted
weighted average shares of common stock.
