[1] | The effect of the assumed conversion of certain convertible units had an anti-dilutive effect upon the calculation of Income from continuing operations per share. Accordingly, the impact of such conversions has not been included in the determination of diluted earnings per share calculations. Additionally, there were 3,255 and 3,446 stock options that were not dilutive as of March 31, 2018 and 2017, respectively, and 1,914 shares of restricted stock that were not dilutive as of March 31, 2018.
