​ In periods for which we have a loss, basic net loss per share is the same as diluted net loss per share. We have excluded from our calculation of diluted loss per share all potentially dilutive in-the-money (i) share options, (ii) non-vested restricted share awards and (iii) shares that were issued upon conversion of two different convertible notes as their inclusion would have been anti-dilutive. The weighted-average number of potentially dilutive securities that were not included in the diluted per share calculations because they would be anti-dilutive were as follows: ​
