______________________
1 Preferred stock dividends were excluded from diluted earnings per share for the years ended December 31, 2015 and 2014, respectively, as the assumed conversion of the outstanding preferred stock would have been anti-dilutive.
2 For the period from September 13, 2016 through December 31, 2016, less than 0.1 million potentially dilutive securities, represented by restricted stock units, had the effect of being anti-dilutive and were excluded from the calculation of diluted earnings per common share. For 2015 and 2014, respectively, approximately 30.2 million and 26.6 million potentially dilutive securities, including the Series A and Series B Preferred Stock, stock options and restricted stock units had the effect of being anti-dilutive and were excluded from the calculation of diluted earnings per common share.
