[1] | Our participating securities do not have a contractual obligation to share in losses; therefore, when we have a net loss, none of the loss is allocated to participating securities. Consequently, for the three months ended March 31, 2017 and 2016, the two class method did not have an effect on our net loss per ordinary share calculation, and as such, dividends paid during the year did not impact this calculation.
[2] | Net loss per ordinary share amounts were calculated from exact, not rounded net loss and share information.
