Ordinary shares Note 1 - Share consolidation of 10 to 1, which was approved by the shareholders at the Annual General Meeting on 15 November 2017, occurred in the prior financial year. Note 2 - Section 258F of the Corporations Act allows a company to reduce its share capital by cancelling any paid-up share capital which is lost or is not represented by available assets. The directors believe that $162,223,185 of the parent entity’s share capital satisfies the criteria in Section 258F of the Corporations Act and accordingly this amount of the ordinary share capital was cancelled in the prior financial year.
