______________________
1 | Net income attributable to participating securities for a given period includes both distributed and undistributed net income, as applicable. Distributed net income attributed to participating securities represents dividend and dividend equivalents declared on the participating securities that the Company expects to ultimately vest. Undistributed net income for a given period, if any, is apportioned to common stockholders and participating securities based on the weighted- average number of securities outstanding in each class during the applicable period as a percentage of the combined weighted-average number of these securities outstanding during the period. Undistributed losses are not allocated to participating securities, however, as the holders of such securities do not have an obligation to fund net losses of the Company.
