Options granted to employees (see Note 17) are considered to be potential ordinary shares. These securities have been excluded from the determination of basic losses per shares. They have also been excluded from the calculation of diluted losses per share because they are anti-dilutive for the years ended June 30, 2018, 2017 and 2016. Shares that may be paid as contingent consideration (see Note 13(b)) have also been excluded from basic losses per share. They have also been excluded from the calculation of diluted losses per share because they are anti-dilutive for the years ended June 30, 2018, 2017 and 2016.

The calculations for the years ended June 20, 2018, 2017 and 2016 have been adjusted to reflect the bonus element in the entitlement offer to existing eligible shareholders which occurred during September 2017.
