C.3 |  | Contributed equity
Recognition and measurement Issued capital Ordinary shares are classified as equity and recorded at the value of consideration received. The cost of issuing shares is shown in share capital as a deduction, net of tax, from the proceeds. Reserved shares Reserved shares are the Group’s own equity instruments, which are reacquired for later use in employee share-based payment arrangements or the Dividend Reinvestment Plan (DRP). These shares are deducted from equity. No gain or loss is recognised in the income statement on the purchase, sale, issue or cancellation of the Group’s own equity instruments.
