[1] The effect of the assumed conversion of certain convertible units had an anti-dilutive effect upon the calculation of Net income available to the Company's common shareholders per share. Accordingly, the impact of such conversions has not been included in the determination of diluted earnings per share calculations. Additionally, there were 0.3 million, 0 million and 1.2 million stock options that were not dilutive as of December 31, 2022, 2021 and 2020, respectively.
