[1] | For the three months ended March 31, 2016 and 2015, the effect of certain convertible units would have an anti-dilutive effect upon the calculation of Income from continuing operations per share. Accordingly, the impact of such conversion has not been included in the determination of diluted earnings per share calculations. Additionally, there were 5,235,280 and 6,857,810 stock options that were not dilutive at March 31, 2016 and 2015, respectively.
