(1) | Under the two-class method of computing earnings per share in accordance with GAAP, income (loss) allocated to participating securities is calculated independently for each quarter and year-to-date period. Therefore, the sum of the amounts for the quarter may not agree with the amounts for the year.
​
(2) | For the three and six months ended June 30, 2020, and 2019, the participating securities have been excluded from the computation of diluted net income per share as such inclusion would be anti-dilutive.
