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
3.3
million and
3.4
million stock options that were
not
dilutive as of
March 31, 2018
and
2017,
respectively, and
1.9
million shares of restricted stock that were
not
dilutive as of
March 31, 2018.
 
The Company's unvested restricted share awards contain non-forfeitable rights to distributions or distribution equivalents. The impact of the unvested restricted share awards on earnings per share has been calculated using the
two
-class method whereby earnings are allocated to the unvested restricted share awards based on dividends declared and the unvested restricted shares' participation rights in undistributed earnings.
